Working processes in the technological sewing process are performed on machine systems characterized by machine-manual work, where the worker and the machine work simultaneously. Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.

Technological processes differ from each other. Accordingly, the devices on which these technological processes are implemented also differ. As a rule, the optimal solution is to select the right machine or device for each process. This facilitates the entire process even in the event of a breakdown of any device on the production line. Such a machine can be replaced by another machine, manual labor, or the operation can be completely excluded. And if all technological operations are carried out on one machine, then its failure will lead to a complete stop of the entire technological process. The issue of processing the Caucasian rhododendron is considered and an innovative technology is presented, according to which its leaves are shock-frozen, crushed, freeze-dried and the product gets a light smoke aroma. It is shown that the use of different devices for each operation of this technological process can lead to microbiological clogging of raw materials, significant loss of cold and complicate the design of all equipment. Therefore, this process is best carried out in one universal device. A schematic diagram of a new device for processing rhododendron is presented, which ensures all technological operations (shock freezing, frozen leaf grinding, freeze-drying and giving the final product smoke aroma and bitter taste) without contact of the raw material with ambient air.

Prospects and trends of this kind are especially important to be known and taken into account at the stage of the preliminary design of the considered human-machine interfaces.

Purpose The purpose of this paper is to improve the operation and maintenance intelligence of power systems, and summarize the transmission line robots and their key technologies. High-voltage power cables are important channels for power transmission systems. Their special geographical environment and harsh natural environment can lead to many different faults. At present, such special operations in dangerous and harsh environments are performed manually, which have not only high labor intensity and low work efficiency but also great personal safety risks. Design/methodology/approach For maintenance works that are far away from the tower, power outages are required. With the increasing evaluation of transmission quality and operational safety, and the urgent need for automation and operation of modern power systems, the contradiction between this manual operation and modern high-quality power transmission has become increasingly prominent. An effective method to replace the manual maintenance work is to use the mobile robot to carry the operation manipulator and its end tool, that is, the live maintenance robot. Findings Some achievements have been made in the key technologies of live maintenance robots, the work to be done to meet the basic requirements of complex and changeable line environment and practical application. Based on the existing research results of live overhaul robot, the follow-up research will focus on the practical application needs and the frontier of scientific and technological development, and truly realize the human–machine integration between live overhaul robot–human working environment. Only in this way can the robot better serve the operation and maintenance of the power system. Originality/value This paper reviews the system platform, operation function, structural characteristics and key technologies involved in the power cable robot, and the combination of live maintenance robots and modern high-tech such as big data and cloud computing is also given, and finally, the future development direction of the special operation robot is pointed out.

This paper puts forth an overall plan of integrated control system based on PLC and touch screen according to the technological requirements of wire ropes cleaning and detection line. It introduces an automation control system composed of two parts by touch screen and PLC automation control system. The core of the control system is the PLC which uses I/O to achieve the control of the switch. Touch screen communicates with PLC by means of RS232 to complete all parameters input and actuators operations. First, it designs various modules of the hardware circuit according to the general scheme. PLC controls rough brush motor, high-pressure water cleaning motor, water drying valve, oil drying valve through I/O module. PLC controls take-up motor by D/A output module. It uses temperature controller to realize automatic heating control in the process of water heating and oil heating. At the same time the temperature controller communicates with PLC by means of RS485. Then, it designs the software of PLC control system which adopts the idea of modular design. As to the software of PLC control system, many programs are designed such as manual control function, automatic control function, communicating function and so on. Finally, it designs the Human Machine Interface system which completes many functions such as manual control operation, automatic control operation, parameter setting, system diagnosis, historical records and help system. The system makes the automation and intellectualization to be realized. It can monitor parameters real-time and improves production efficiency.

The article envisages the increase in the efficiency of NC machine tool due to the use of an upgrades design of turning table for installation and fixing of workpieces, the use of which will lead to improved productivity of machining. With the help of a turning table it is possible to perform machining of workpieces of different shapes from several sides without resetting, and to rotate the workpiece in different coordinates to carry out other technological transitions. Such tables are widely used un multi-position hole machining, milling planes on drilling and milling machines. The workpiece is fastened to the turning table by T-shaped longitudinal seams, and the table can take vertical or horizontal position. Ways to reduce the cost of CNC equipment for small enterprises are analyzed. One possible way is to modernize turning tables by replacing the manual drive. When upgrading the table for replacement of the manual drive a stepper motor is installed, which transmits the movement through the coupling and worm-and-worm gear to the faceplate. Modern stepper electric motors provide movement of the work part with an accuracy of 0.01 mm. In addition, the have good operational life due to the lack of a collector unit (in comparison with servo drives), which is subject to considerable wear during operation. Due to the simplicity of design stepper motors have relatively low cost, which is of great importance in today’s production realities. The analysis of operating life and accuracy of modern stepper motors and the choice of motor was carried out. For integration of the modernized table into the system of CNC metal-cutting machine tool the function of command reading sent from the machine control rack and converting them into the direction (DIR) and pitch (PULSE) is proposed to solve this problem. The effect of changing the design of the positioning mechanism on accuracy control is also shown.

Manual skill degradation is a common problem that production managers face in assembly lines due to frequent changes in batch styles. Since the advancement in automated machinery, reliance on manual machines has been reduced. However, due to the high cost of fully automated machinery, it is still not available on a large scale in apparel manufacturing setups as most of the setups are in developing countries. Few related studies regarding the effects of automation on manual skills have been conducted in aviation and other emerging technological advanced fields; little focus was given on the effects of automation in apparel manufacturing. This exploratory study examines automation-induced performance degradation in the apparel production line. Sixty-seven sewing machine operators were initially trained on manual sewing machines to learn a complex production operation. Then, participants were divided randomly into three groups to experience varied amount of automation exposure. The manual machine group (MMG)kept working on the manual machines after the initial training and skill development. In contrast, the automation group (AG) shifted to automated pocket setting machines after skill development. Finally, the refresher training group (RTG) rotated between manual and automated machines after the skill development. The skill retrieval assessment was carried out after six weeks in the production line. The result of an independent t-test showed no significant differences among performances of the three groups after the initial training stage. A significant increase in the average single cycle time (ASCT) and decrease in the right-first-time percent (RFT %) was found in the AG while the ASCT decreased and the RFT% increased among the MMG after the retention interval. The RTG almost maintained its production output and the ASCT due to refresher training drills. Relevance to industry: Production managers usually maintain a skill set among the operators to run the production line smoothly. Therefore, capacity development drills of sewing operators are essential to maintain an efficient required skill set.

Purpose This paper aims to present a comprehensive analysis of deburring effectiveness and surface layer properties after deburring process by wire brushing from milled 7075 aluminium alloys objects. Edge states (rounding, chamfering), surface roughness around the edge, microhardness and residual stress distribution were analyzed. Design/methodology/approach During the machining process, undesirable phenomenon occurs, which is the formation of burrs at the edges of workpieces. They occur in most elements formed by machining. There are many methods that can be used for deburring, but in the case of large components, typical of aerospace industry, using certain methods becomes difficult or uneconomic. Taking advantage of the fact that a part is mounted on the machine, it is advisable to make deburring operation the last action. This operation can be carried out by wire brushing. Findings On the basis of conducted studies, it was demonstrated that it was possible to choose such technological brushing conditions as to ensure an effective process of deburring, form appropriate edge state and generate the desired surface layer properties. Practical implications The method presented in the article allows for efficient, automatic deburring, especially for large components made of 7075 aluminium alloy. This eliminates manual, time-consuming methods of removing burrs by locksmiths. Moreover, the results allow to evaluate changes occurring in the surface layer after brushing process. Originality/value Results of brushing experiment provide full information on selection of technological parameters to obtain the required surface roughness and edge state. Moreover, analysis of surface layer properties (microhardness, residual stress) allows to assess the degree of impact hitting fibre on the workpiece.

Fruits and berries are valuable foods that provide the necessary for human consumption: sugars, proteins, fats, mineral salts, organic acids,pectin, tannins and other substances, vitamins. Also raw materials for the food industry, which are used to make juices, jams, marmalades, jams. Due to the crisis, which covered all areas of human activity in Ukraine, the average annual consumption of fruits and berries per unit of population is less than 50% of the biologically justified norm; the area of orchards is 2.7% of the total area of agricultural land (0.8 million hectares), of which 60% is apple orchards. Improving the situation is possible through the intensification of horticulture - obtaining maximum annual yields through the introduction of the latest advances in science and technology, including in the field of mechanization of fruit production. The most time-consuming operation in the technological process of fruit production is harvesting, which, in particular for apples, accounts for 15-40% of the total cost of garden care. It can be emphasized that the cost of growing apples is 92 times higher than for a similar area of cereals. The solution to this problem is possible through the introduction of fruit harvesters, the use of which allows to increase productivity by 3.7-12.6 times, to release an average of 50 people. per day from the use of one machine and reduce operating costs by 30-50% compared to manual assembly. The most widespread at present for fruit harvesting, as evidenced by the trends of the world agricultural machinery industry, are stem vibrating machines of positional action with inertial linear working bodies. At the same time, the use of serial fruiting means, due to the impersonal process of removal, causes damage to trees and fruits, which are suitable mainly for technical processing or urgent sale in fresh form; the productivity of serial fruit harvesters is relatively low.

When foreign companies supply equipment for production of class A500 and B500 cold rebars to the Russian market, the manufacturer as a rule estimate its production indices by generally accepted parameters: machine utilization index (MUI), drawing speed and bars diameter (sometimes with specific differentiation). Usually, MUI and drawing speed are presented as the highest reached parameters without accounting particular conditions of operation at a customer, and sometimes – without configuration of the equipment. With a high price of equipment, a customer often gets low efficiency coefficient of correspondence between the high production parameters announced by the manufacturer and those being realized in practice. It was shown that drawing lines for production rebars of the class mentioned above, are typical by equipment content, for example unreeling and power segments. The difference can be only in coiling equipment segment. Such an equipment refers to equipment of cycling products discharge, which is done only at a coil change (a full coil for an empty one). Accumulation of tonnage is provided by a number of coils, which as a result (of a shift, day, month and a year) makes a production program of such drawing lines. If the change of coils at any coiler configuration (automatic, semi-automatic or manual) requires halt of the drawing line, then such halts must be accounted in the time balance of line operation and down times. Accounting of them can considerably change the announced production indices. Per se the production program of such drawing lines should be made taking into consideration actual MUI, but not the advertising one. Results of monitoring of contractual data of some foreign companies presented, to evaluate actuality of the announced by them indices of the equipment production program, supplied at the Russian market. The calculations of down times accounting change time and coils tonnage, as a relative index of drawing lines productivity and their analysis showed that the advertising data presented in the analyzed contracts, cannot be considered as representing and reference ones for making commercial production program of a customer. A method of calculation proposed and recommendations presented, which any customer can use when making inquiry for purchasing drawing equipment from any manufacturer. Also, the method can be used for internal monitoring of in-house production under conditions of particular state of engineer infrastructure and level of automation and mechanization of basic technological operations.

Faults in electrical facilities may cause severe damages, such as the electrocution of maintenance personnel, which could be fatal, or a power outage. To detect electrical faults safely, electricians disconnect the power or use heavy equipment during the procedure, thereby interrupting the power supply and wasting time and money. Therefore, detecting faults with remote approaches has become important in the sustainable maintenance of electrical facilities. With technological advances, methodologies for machine diagnostics have evolved from manual procedures to vibration-based signal analysis. Although vibration-based prognostics have shown fine results, various limitations remain, such as the necessity of direct contact, inability to detect heat deterioration, contamination with noise signals, and high computation costs. For sustainable and reliable operation, an infrared thermal (IRT) image detection method is proposed in this work. The IRT image technique is used in various engineering fields for diagnosis because of its non-contact, safe, and highly reliable heat detection technology. To explore the possibility of using the IRT image-based fault detection approach, object detection algorithms (Faster R-CNN; Faster Region-based Convolutional Neural Network, YOLOv3; You Only Look Once version 3) are trained using 16,843 IRT images from power distribution facilities. A thermal camera expert from Korea Hydro & Nuclear Power Corporation (KHNP) takes pictures of the facilities regarding various conditions, such as the background of the image, surface status of the objects, and weather conditions. The detected objects are diagnosed through a thermal intensity area analysis (TIAA). The faster R-CNN approach shows better accuracy, with a 63.9% mean average precision (mAP) compared with a 49.4% mAP for YOLOv3. Hence, in this study, the Faster R-CNN model is selected for remote fault detection in electrical facilities.

The importance of the fishing industry as one of the backbone industries in the economic activity of the Far Eastern region is noted. The orientation of fish processing enterprises in the region to the processing of salmon fish is shown. The average catch of salmon fish in the Far East is presented; the share of caviar products from this valuable water body in the volume of catch is shown. The expediency of modernization of the technological process in the processing of salmon fish in order to increase the yield of food products and their biological value has been substantiated. An assessment of the chemical composition of wastes generated during the production of salmon caviar at the operation of punching ovaries is given, confirming their nutritional value, as well as the expediency of collecting and using this secondary raw material. The composition of the generated waste is described. Their relative biological value was determined by the biotesting method using the ciliate Tetrahymena pyriformis. Two types of punching of salmon ovaries are considered: manual and machine, as well as technical design of the technological process, which affect the yield of punched eggs and the amount of waste generated in this case. A device for punching salmon caviar is presented, and the principle of its operation is described. It is indicated that the collection of the studied waste is difficult due to the design features of the technological line. The developed automatic aggregate-technological scheme of the line for collecting waste from punching salmon ovaries is presented, which includes a device for punching eggs, a liquid ring vacuum pump, a vacuum barrel, a magnetic float level switch, a sluice gate, a waste container with a water separating grid and a control cabinet. It is shown that the proposed aggregate-technological scheme provides an opportunity to accumulate valuable waste with different water content, differentiating them according to this feature. It is concluded that the proposed technical solution for the automatic collection of waste generated during the punching of salmon ovaries will make it possible to obtain biologically valuable secondary raw materials for further use in the production of food products.

This paper describes the procedures used in a technologically orientated numerically controlled (NC-) system to determine the optimum culling conditions automatically for turning, drilling, grooving, threading and parting-off operations. In rough turning, the optimum depth and feed combination is determined using a direct search procedure on the allowable depth/feed region for chip control. The system determines the optimum depth of cut, feed and velocity for each pass in multi-pass turning on the basis of a user-selected objective criterion and a number of technological limitations that may apply to the process, such as machine power, dynamic instability, allowable range of depths and feeds for the tool and workholding limitations which include axial slip, circumferential slip and component throw-out. A user-friendly manual option is also provided which allows the user to specify the cutting parameters. Examples are given to illustrate how these procedures determine the optimum cutting conditions. A comparison between the machining costs and times using cutting conditions obtained from handbooks and the aforementioned procedures shows that for all the operations considered, there are cost and time savings when the cutting conditions obtained by the latter are used.

For the past decade, Industry 4.0 has become the basis for building competitive advantage for business operations. The key technologies of Industry 4.0 are implemented in enterprises of various industries. This paper focuses on presenting the results of research on the influence of the Industry 4.0 concept on the operations of enterprises that are implementing smart manufacturing (SM) projects. The paper analyses the following areas of influence of projects on the enterprises’ operations: productivity, agility and speed, quality, competitiveness and enterprise value, profitability, staff reduction, delivery improvements, vertical and horizontal integration, resource savings, reduction of operating costs, technology adaptability and quality of machine operations. The paper belongs to the research paper category. The research tool was a questionnaire. The research was carried out in the segment of steel enterprises in Poland. The results of the presented research belong to pilot research of a segment of steel industry in Poland. The main conclusion of the study is that implementation of Industry 4.0 in the Polish steel sector had a positive influence on many factors strictly connected with the innovativeness of the company. Especially, the implementation of this conception in the steel sector leads to an increase in the quality of the product and the possibility to achieve a good level of customization of the product. Those factors are very important for the steel sector potential to succeed on the competitive market. The individual SM projects that were evaluated were a form of case study. The participants of the research were employees in managerial positions and operating technological installations in steel sector enterprises. In the opinion of the surveyed (79 people), depending on the type and scope of changes implemented in the company in the direction of Industry 4.0, decision-makers expect a higher quality of processes and products, the ability to meet customer requirements—the direction of the personalization of products and services, agility and flexibility of performed operations with the use of smart technology and accuracy and precision of performance higher than in the case of manual human activities.

This research aims to establish the influence of different factors on the dimensions accuracy in laser cutting. Samples with different thickness were made of DC01 EN 10130 steel. On each sample 32 round or square holes were cut in 4 rows by different laser beam movement schemes linear, zig-zag and random. The tests were made by pulse CO2 laser with regimes, recommended for each sheet thickness, by the machine operating manual. The diameters of the round holes and the dimensions of the square holes along the laser head and the table axes were measured by a projector. The varying intervals of the dimensions and the shape deviations were calculated. It was established that three groups of factors influence on the dimensions accuracy in laser cutting: factors, related to the machine, laser parameters power, laser cutting speed and focus distance, determining the technological process parameters, and the material characteristics thermal physical properties and sample sizes. Factors, related to the machine, exert effect mainly on the intervals of dimensions varying, while the laser parameters and the material properties influence on the dimensions value independently of the cutting scheme. In the all laser cutting schemes the increasing of the sample thickness leads to the larger interval of the dimensions varying and increasing of the shape deviation. Nomenclature

The paper describes the developed automated device for the formation of electrocatalytic layers used in electrochemical systems, and the issues of development of the sputtering technology, which allows to obtain the best parameters of the formed active layers. The general scheme of the automated device includes a system of automatic positioning of the spraying head according to two coordinates, driven by stepper motors controlled by a personal computer, an ultrasonic mini-disperser, a spraying head, ultrasonic generators for the ultrasonic mini-disperser, and the ultrasonic spraying head. Stepper motors were controlled by microprocessor system based on 8-bit Atmel AT90S2313 single-chip microcontroller and standard buffer microcircuits. The key actuating element of the device and the process is the developed atomizing head with an integrated ultrasonic homogenizer that prevents sedimentation of the catalytic composition. The overall automation circuit designed and reproduced to control all electronic devices was described in detail. It differed by application of Attiny2313 microprocessor for the control, availability of communication with personal computer via RS-485 interface that allowed not only to switch the disperser on/off, but also to control its working frequency directly from the personal computer. It was envisaged both manual control of stepper motor controller via control buttons and control from external personal computer, which had the opportunity to control spraying program step by step. In this case all the sequence of steps is contained in the personal computer memory, it is transmitted to the stepper motor controller step-by-step as the program is being executed. Algorithms for moving the spraying head that provide the best drying of catalytic composition in the process of its application have been developed. The effectiveness of the developed automated device has been shown by comparing it with manual application by a specialist according to such criteria as the rate of application of electrocatalytic layers and their quality. The created device, algorithms of its operation, software and scientific and technological advance, in general, can be used for the formation of various coatings both in electrochemical technologies and in other fields.

An essential prerequisite for the success of students' independent work with textbooks should be considered their sufficient awareness of the existence of textbooks. It is unacceptable to hope that the student himself is orientated in this. Therefore, in the introductory lessons, each teacher should familiarize students with the school's books and drawings in the school library with textbooks, give them an exhaustive description, pay attention to the advantages and disadvantages of each of them.Experience shows that, having such knowledge, students experience difficulties working with the content of the manual in the drawing. The educational literature in the drawing reflects the peculiarities of technical knowledge, and the formation of the ability to obtain knowledge from it without these features is impossible. The reason for this, in our opinion, is that the material of any tutorial in the drawing is rather heterogeneous. Therefore, the usual drawing up of a plan, abstract or abstract will not help to realize it. It is for this reason that the need arises to take into account when developing the skills of independent work with educational material from the drawing, the nature and specificity of those concepts that are present in the training manual of the drawing.The ability to independently work with the text is actually a complex skill, which is based on a variety of perception and thinking operations. The analysis of the content of the manual in the drawing shows that it has a rather complex structure (theoretical information, alternating with normative materials, technical and technological information), includes a heterogeneous purposeful material informative and descriptive. Acquiring such educational material requires abstract, figurative and visual-action thinking, the ability to imagine in the dynamics of specific graphic actions or transformations.One of the important and complex tasks that students have to do in the process of mastering the contents of the school curriculum of the drawing, is the use of knowledge from various fields of knowledge: materials science, technology of processing structural materials, the basis of standardization and technical measurements, machine parts, etc. For independent work with the theoretical material of the manual, the drawing requires skills that make it possible without the help of the teacher to understand and remember the unknown material previously.First of all there is a need to teach students to use the book orientation apparatus, that is, to understand its structure - content (titles of sections, paragraphs, etc.).An important place in the study to independently elaborate the theoretical material of the textbook, we devote to the formation of the ability to answer the questions asked, because it is well known that emotional and cognitive attitude to learning occurs when it is organized as a search for the answer to the question.

Степень технологической и технической зависимости отечественных производителей овощных культур от зарубежных производителей с.-х. техники, а также их техническая оснащенность специализированными машинами объясняется высокими затратами на производство овощей, особенно на уборку, что при общем дефиците ручного труда приводит к сокращению площадей, нарушению технологии выращивания и соответственно снижению урожайности. Цель исследований – определить современное состояние технологического и технического обеспечения производства овощных культур в Российской Федерации. Для достижения поставленной цели использовали методологию системного анализа и синтеза, математической статистики, численные методы решения аналитических зависимостей. Статистические исследования современного состояния технического обеспечения производства овощей в России могут служить основой для построения модели и разработки концептуальных принципов модернизации технологического и технического обеспечения работ в овощеводстве. Определена потребность товаропроизводителей в современных высокотехнологичных комплексах машин для производства овощных культур. Проведенные статистические исследования позволили оценить современное состояние с.-х. машиностроения по выпуску необходимого для товаропроизводителей количества машин. Повышение объемов производства овощной продукции неразрывно коррелирует с уровнем технического обеспечения отрасли овощеводства в целом, что подтверждает уровень локализации с.-х. машиностроения РФ, а также Беларуси и Казахстана, где с.-х. машиностроение представлено широкой номенклатурой предприятий, выпускающих комплексы машин от предпосадочной обработки почвы до послеуборочной обработки товарной продукции. Для возрождения с.-х. машиностроения и развития рынка средств механизации аграрного производства определены основные механизмы обновления парка сельхозтехники – преимущественно привлечением кредитных ресурсов коммерческих банков и лизинговых компаний. Кроме того, интенсивность ведения сельского хозяйства в современных условиях производства невозможна без высокого уровня насыщения машинно-технологических комплексов средствами интеллектуализации. Получать качественную конкурентоспособную продукцию можно только при использовании современных высокопроизводительных машин, обеспечивающих совмещение технологических операций, в конструкциях которых заложены системы автоматизированного управления технологическими процессами, учета почвенного плодородия, обеспечения экологической чистоты агроландшафтов. The degree of technological and technical dependence of domestic producers of vegetable crops on foreign producers of agricultural machinery, as well as their technical equipment with specialized machines, is explained by the high costs of vegetable production, especially for harvesting, which, with a general shortage of manual labor, leads to a reduction in area, disruption of cultivation technology and, accordingly, a decrease in yield. The purpose of the research is to determine the current state of technological and technical support for the production of vegetable crops in the Russian Federation. To achieve this purpose, we used the methodology of system analysis and synthesis, mathematical statistics, numerical methods for solving analytical dependencies. Statistical studies of the current state of technical support for vegetable production in Russia can serve as a basis for building a model and developing conceptual principles for modernizing technological and technical support for work in vegetable growing. The need of commodity producers for modern high-tech complexes of machines for the production of vegetable crops is determined. The conducted statistical studies made it possible to assess the current state of agricultural engineering for the production of the number of machines necessary for commodity producers. The increase in the production of vegetable products is inextricably correlated with the level of technical support for the vegetable growing industry as a whole, which confirms the level of localization of agricultural machinery in the Russian Federation, as well as in Belarus and Kazakhstan, where agricultural machinery is represented by a wide range of enterprises that produce complexes of machines from pre-planting tillage to post-harvest processing of commercial products. For the revival of agricultural machinery and the development of the market of agricultural production mechanization tools, the main mechanisms for updating the agricultural machinery fleet are determined-mainly by attracting credit resources from commercial banks and leasing companies. In addition, the intensity of agriculture in modern production conditions is impossible without a high level of saturation of machine-technological complexes with means of intellectualization. It is possible to obtain high-quality competitive products only with the use of modern high-performance machines that ensure the combination of technological operations, in the designs of which there are systems for automated control of technological processes, accounting for soil fertility, ensuring environmental cleanliness of agricultural landscapes. Key words: vegetable growing, vegetable seeders, transplanters, vegetable harvesting equipment.

В статье рассматривается комплекс вопросов, способствующих повышению безопасности рыбных консервов как важнейшего показателя качества пищевого продукта и оптимизации расхода ресурсов. Показана целесообразность замены традиционного метода орошения блоков замороженной рыбы на электроконтактный способ, который существенного повышает производительность и улучшает качество размороженного сырья. Уменьшение ручного труда в рыбоконсервном производстве может быть достигнуто использованием роботов и робототехнических комплексов на стадиях приемки и порционирования сырья, фасования продукта, проверки герметичности и удаления негерметичных консервов. Применение системы технического зрения позволяет организовать непрерывный дистанционный контроль закаточного шва и изменять параметры настройки закаточной машины с целью достижения необходимой герметичности. Показано, что безопасность производства консервов может быть повышена облучением рабочих поверхностей продукта и оборудования ультрафиолетовым излучением. На безопасность консервов оказывают влияние практически все технологические операции рыбоконсервной линии.

The article deals with a set of issues that contribute to improving the safety of canned fish as an important indicator of food quality and the resource consumption optimization. The utility of replacing the traditional method of irrigation of frozen fish blocks with an electric contact method is shown, the latter significantly increasing productivity and improving the quality of thawed raw materials. Reduction of manual labor in fish canning production can be achieved by using robots and robotic systems at the stages of acceptance and portioning of raw materials, product packaging, leak testing and removal of leaky canned food. The use of a technical vision system allows to organize continuous remote control of the sealing seam and change the settings of the sealing machine in order to achieve the necessary tightness. The safety of canned food production is shown to be increased by irradiating the working surfaces of the product and equipment with ultraviolet radiation. The safety of canned food is influenced by almost all technological operations of the fish canning line. The analysis of investigations into the technology of products from hydrobionts and the development of automated canning lines has allowed to identify measures to further improve the production and storage of canned fish.

Savings and Credit Co-operative Societies (Saccos) in Kenya have realised a tremendous growth in the subsector and are investing huge amount of their scarce financial resources in digital technology to enhance services delivery and offer a wide variety of products and services range, increased membership mobilisation and size, ensure better structure and effective financial performance. Digital financial Services as used in the Saccos industry is as a result of Information Communication Technology revolution commonly referred to as digital commerce. Many Saccos are steadily changing from manual banking system of operations to providing digital Financial (e-banking) services that include internet banking, M-banking and Automated Teller machine support. The adoption of digital financial Services by the Saccos is a strategic attempt to deal with increased cut throat competition from traditional banking institutions and non-banking financial institutions, to cut costs and add value to their services in order to optimise benefits to the shareholders. Despite the fact that Saccos have rapidly adopted digital financial services to provide services, and that they drive a huge section of the financial sector savings of the economy, they have experienced various challenges such as uncertainty and risk due to digital financial services. The study sought to establish the influence of digital financial services on the financial performance of SACCOs in Kakamega County, Kenya. The specific objectives was to determine the effect of the mobile banking, internet banking, use of credit cards and digital funds transfer on the financial performance of SACCOs in Kakamega County, Kenya. The research was guided by three theories of innovation and technology: Diffusion of Innovation Theory, The Theory of Task-Technology Fit Theory and the Technological context, Organisational context and Environmental context Theory.The study used a descriptive research design. The population of study were staff at the three SACCOs operating in Kakamega County. This consisted of 162 respondents who are the staff of the SACCOs. A sample of 49 respondents was taken which forms 30% of the target population which shall be evenly spread across the three SACCOs. The primary data was collected by use of self-administered semi-structured questionnaire.Collected data was analysed through descriptive and inferential statistics by the use of SPSS. Findings were presented by use of tables, frequencies, percentages, means and standard deviation.The study found that the financial performance of the SACCOs was significantly influenced by the digital financial services instituted by the SACCO managements. They demonstrated to have reliable mobile banking system where most of their customers had enrolled on the mobile banking platform and most of customer queries and updates were sorted via the mobile platform.Given the limitations and findings of this study, the researcher recommends that since there exists a positive relationship between digital financial services and bank performance and that e-banking has brought services closer to bank customer’s hence improving banking industry performance, SACCOs must also enhance the dynamics of the sector and embrace digital banking fully and extensively. Mobile banking faces various challenges among them being, system delays by the mobile money transfer service providers, slow processing of transactions, high transactions costs, limit on the amount of money that can be withdrawn in a day and fraud.

Abrasive reinforced wheels in combination with the use of manual and stationary grinding machines are widely used in construction and installation work and are among the most common types of hand tools. Domestic and foreign manufacturers of abrasive tools offer products for cutting, cleaning and grinding operations with different design and physical and mechanical properties for processing various materials. The optimal choice of technological and technical parameters of machines, combined with the correct selection of the required abrasive working tool, allows to reduce labor intensity and increase productivity and quality of work with the desired effect [1 ... 4]. It should be noted that the work of such machines is often carried out in an awkward position, at the cost of large additional and unreasonable efforts at high speeds of operations. The process of working with manual grinding machines (including those with abrasive reinforced wheels) has a number of features, they include: instability of the supply in size and direction; continuous change within the allowable power of the drive intensity of the work process; limiting the forces arising at the point of contact of the working tool (abrasive reinforced circle) with the working environment, both the power of the drive and the individual physiological data of the operator. The task of improving working conditions, improving the efficiency of the use of machines for construction and installation work and ensuring the safe operation of the operator requires a comprehensive assessment of the production environment of operators, taking into account the principles of ergonomics. With a clear shortage of manpower during construction and installation and repair work, such a factor in increasing labor productivity as maximum use of labor resources through the creation of comfortable working conditions and the involvement of ergonomically sound tools and its mode of operation can no longer be ignored. -ся. The analysis carried out by the authors [5, 6] of interaction in the system "operator - machine - working environment" when working with angle grinders equipped with cutting and cleaning abrasive reinforced working bodies shows a close relationship between the load on the working body and effort which are perceived by the machine operator, due to the significant influence of the operating parameters. Determining the load on the working body, based on technological conditions is an urgent task, as in the process of abrasive reinforced wheels torque on the spindle and rotation of the working body is created by the drive of the machine, and all other functions - longitudinal and transverse feed, maintenance of the car and general management - are carried out by the operator. When working with hand grinders, the operator can hold it in any position and ensure a sufficiently precise feed direction of the wheel.

The purpose of the research: comprehensive assessment of the individual milking unit of the company "Kurtsan" (Turkey) during operation. Methods of research: Analysis of the structural features of the individual milking unit performed by the observation method given to test sample, the quality of the machine was evaluated by standardized methods: the quality of the technological process and operational-technological indicators in accordance with the SOU 74.3-37-273, energy indices according to DSTU 2331, economic Indicators according to DSTU 4397, safety indicators and ergonomics according to DSTU IEES 60335-1, DSTU EN 60335-2-70. Research Results: The conducted research confirms a sufficiently high quality of the technological process of selection of milk in cows in the conditions of use of milking installation in a personal economy, which provides favorable conditions for the milking of the cow, taking into account its physiological features. Performance per hour of basic time is 10 heads. Milking installation works on the principle of a closed milking system, thanks to which milk does not contact the environment and immediately from the basin enters a sealed can. Such system protects milk from the possibility of bacterial and physical contamination. Milk obtained during milking by milking installation according to quality indicators (acidity, density, content of somatic cells, mass fraction of dry matter, mass fraction of fat) meets the requirements for the first grade according to DSTU 3662. Milking installation is equipped with a dry vacuum pump. Power consumption during installation does not exceed 0.54 kW. Specific electricity consumption for milking of one cow is 0.05 kWh / head. Annual operating expenses for milking of two cows in the farm are 1591.90 UAH / head. Conclusions. According to the testing of the individual milking plant manufacturing company "KURTSAN", it has been established that this installation reliably performs the technological process of machine milking of cows in milking can for their tethered maintenance and allows you to get milk of the first grade. The total duration of visiting one cow is 5.75 minutes. The average intensity of milk is 1.0 kg / min. Milking machine provides complete bodies of cows. The magnitude of the control manual feed is 50 ml. The milking machine is equipped with an adjustable pulsator of pairwise milking, which creates a manual milking process and works for a working vacuum of 40 ± 1 kPa, which prevents injury to dies and diseases of mastitis. In the cover the "Stop-Milk" system is installed, which prevents milk from entering a vacuum pump during the overflow of the poor, or water while washing All items are compactly assembled on a single cart. However, a small diameter of wheels on an unequal surface creates some inconvenience to the operator during the transportation of the machine with a filled milk capacity. The application of the installation increases the amount of milk received. Its gentle work does not harm the emotional and physical health of the cow: the dysfunctions during operation are not pushed, and light vibration creates a massage effect. Milking installation allows you to significantly reduce the labor of service personnel in an economy with a maintenance of 1 to 10 cows.

Off-site construction constitutes a paradigm shift in construction promoting improved sustainability. At present, North Americaäó»s building construction sector is still dominated by conventional stick-built construction, which is prone to excessive material waste, longer cycle times, high labour costs, and lower quality. In contrast, inspired by the manufacturing industry, off-site construction is an approach in which building components are prefabricated in factories and transported to the construction site for on-site assembly. As the concept of off-site prefabrication gains momentum within the domain of construction, some home builders are bringing the traditional industry practice into a factory setting, thus resulting in stick-building- under-a-roof. This paper describes the development of simulation models for the automated light gauge steel framing process using discrete-event simulation mimicking real-time machine production capacity and cycle time. At present, the literature on the development of such models for automated construction machinery is lacking; in this context, this paper aims to showcase the advantages of simulation as a decision-making support tool. Construction of such models provides a useful tool for understanding bottlenecks in machine operations that can be addressed to meet local demands. Since the steel framing process primarily consists of manual assembly and fastening of cold-formed steel (CFS) frames, these models showcase the potential to increase the level of automation through the addition of various mechanical and control modifications to an existing prototype steel framing machine. The results show that cycle time reductions of 13 percent or greater are possible by applying the proposed modifications.

Manual massage and foam rolling are commonly used by athletes for warm-up and recovery, as well as by healthy individuals for well-being. Manual massage is an ancient practice requiring the intervention of an experienced physiotherapist, while foam rolling is a more recent self-administered technique. These two topics have been largely studied in isolation from each other. In the present review, we first provide a deep quantitative literature analysis to gather the beneficial effects of each technique through an integrative account, as well as their psychometric and neurophysiological evaluations. We then conceptually consider the motor control strategies induced by each type of massage. During manual massage, the person remains passive, lying on the massage table, and receives unanticipated manual pressure by the physiotherapist, hence resulting in a retroactive mode of action control with an ongoing central integration of proprioceptive feedback. In contrast, while performing foam rolling, the person directly exerts pressures through voluntary actions to manipulate the massaging tool, therefore through a predominant proactive mode of action control, where operations of forward and inverse modeling do not require sensory feedback. While these opposite modes of action do not seem to offer any compromise, we then discuss whether technological advances and collaborative robots might reconcile proactive and retroactive modes of action control during a massage, and offer new massage perspectives through a stochastic sensorimotor user experience. This transition faculty, from one mode of control to the other, might definitely represent an innovative conceptual approach in terms of human-machine interactions.

This article analyses discourses around procedural content generation (PCG) as automation of creativity in the games industry. PCG refers to techniques for creating game content algorithmically, by manipulating data through sets of computational operations and parameters. By producing scalable results with combinatorial diversity, procedural generation is touted as the future of content, yet flouted as the harbinger of technological unemployment in game art production. Critical scholarship on automation suggests that the real danger is not job loss per se, but the constitution of an underclass of artists whose vital work of conditioning algorithmic outputs is denigrated as derivative and ‘manual’. Framed by liberal humanist ideas of agency, PCG naturalizes trade-offs where the autonomy of generative machines is contingent upon the automatism of its human conditioners. This qualitative analyses of talks on PCG at the Game Developers Conference (2015–2020) shows how procedural systems bifurcate the creative work of algorithmic cultural production into affective and mechanical forms of conditioning that map onto stratifications of racial capitalism. Affective tuning resists documentation and is reserved for artists with technomasculine forms of cultural capital; mechanical tuning is relegated to automatable and outsourced labour and relies on replicable technique that is considered artistic but not creative. This article argues that PCG’s reclassification of creativity through racialised dialectics of human agency and machine automaticity overlooks the autonomy of procedural systems. PCG pipelines are organised less around the agency of human toolmakers and more around the autonomy of systems that assimilate tasks in the management of complex networks of dependencies. Instead of pitting artists against machines, this analysis politicises automation’s racial stratifications by examining the momentum of more-than-human systems in which toolmakers and tool users negotiate granularities of control and degrees of concession.

Digital culture, as we know it, owes much to space exploration. The technological pursuit of outer space has fuelled innovations in signal processing and automated computing that have left an impact on the hardware and software that make our digital present possible. Developments in satellite technologies, for example, produced far-reaching improvements in digital image processing (Gonzalez and Woods) and the demands of the Apollo missions advanced applications of the integrated circuit – the predecessor to the microchip (Hall). All the inventive digital beginnings in space found their way back to earth and contributed to the development of contemporary formations of culture composed around practices dependent on and driven by digital technologies. Their terrestrial adoption and adaptation supported a revolution in information, mediation and communication technologies, increasing the scope and speed of global production, exchange and use of data and advancing techniques of imaging, mapping, navigation, surveillance, remote sensing and telemetry to a point that could only be imagined before the arrival of the space age. Steadily knotted with contemporary scientific, commercial and military endeavours and the fabric of the quotidian, digital devices and practices now have a bearing upon all aspects of our pursuits, pleasures and politics. Our increasing reliance upon the digital shaped the shared surfaces of human societies and produced cultures in their own right. While aware of the uneasy baggage of the term ‘culture’, we use it here to designate all digitally grounded objects, systems and processes which are materially and socially inflecting our ways of life. In this sense, we consider both what Michael Hardt and Antonio Negri describe as “those results of social production that are necessary for social interaction and further production, such as knowledges, languages, codes, information, affects, and so forth” (viii), and the material contexts of these products of the social. The effects of digital technologies on the socio-material ambits of human life are many and substantial and – as we want to suggest here – evolving through their ‘extraterrestrial’ beginnings. The contemporary courses of digital cultures not only continue to develop through investments in space exploration, they are themselves largely contingent on the technologies that we have placed in outer space, for instance, global telecommunications infrastructure, GPS, Google maps, weather and climate monitoring facilities and missile grids all rely on the constellation of satellites orbiting the earth. However, we have been increasingly witnessing something new: modes of social production that developed on earth from the technical demands of the space age are now being directed, or rather returned back to have new beginnings beyond the globe. Our focus in this paper is this outward momentum of digital cultures. We do not aim to overview the entire history of the digital in outer space, but instead to frame the extraterrestrial extension of human technologies in terms of the socio-material dimensions of extra-planetary digital cultures. Hannah Arendt described how the space age accelerated the already rapid pace of techno-scientific development, denying us pause during which to grasp its effects upon the “human condition”. Our treacherously fast technological conquest of outer space leaves in its wake an aporia in language and “the trouble”, as Arendt puts it, is that we will “forever be unable to understand, that is, to think and speak about the things which nevertheless we are able to do” (3). This crisis in language has at its core a problem of ontology: a failure to recognise that the words we use to describe ourselves are always, and have always been, bound up in our technological modes of being. As thinkers such as Gilbert Simondon and Bernard Stiegler argued and Arendt derided (but could not deny), our technologies are inseparably bound up with the evolutionary continuum of the human and the migration of our digital ways of life into outer space still further complicates articulation of our techno-logic condition. In Stiegler’s view the technical is the primordial supplement to the human into which we have been “exteriorising” our “interiors” of social memory and shared culture to alter, assert and advance the material-social ambits of our living milieu and which have been consequently changing the idea of what it is to be human (141). Without technologies – what Stiegler terms “organised inorganic matter” (17), which mediate our relationships to the world – there is no human in the inhuman extraterrestrial environment and so, effectively, it is only through the organisation of inert matter that culture or social life can exist outside the earth. Offering the possibility of digitally abstracting and processing the complexities and perils of outer space, space technologies are not only a means of creating a human milieu ‘out there’, but of expediting potentially endless extra-planetary progress. The transposition of digital culture into outer space occasions a series of beginnings (and returns). In this paper, we explore extra-planetary digital culture as a productive trajectory in broader discussions of the ontological status of technologies that are socially and materially imbricated in the idea of the human. We consider the digital facilitation of exchanges between earth and outer space and assign them a place in an evolving discourse concerned with expressing the human in relation to the technological. We suggest that ontological questions occasioned by the socio-material effects of technologies require consideration of the digital in outer space and that the inhuman milieu of the extraterrestrial opens up a unique perspective from which to consider the nascent shape of what might be the emerging extra-planetary beginnings of the post human. Digital Exurbias The unfolding of extra-planetary digital cultures necessitates the simultaneous exteriorisation of our production of the social into outer space and the domestication of our extraterrestrial activities here on earth. Caught in the processes of mediated exploration, the moon, Mars, Pluto and other natural or human-made celestial bodies such as the International Space Station are almost becoming remote outer suburbs – exurbias of earth. Digital cultures are reaching toward and expanding into outer space through the development of technologies, but more specifically through advancing the reciprocal processes of social exchanges between terrestrial and extraterrestrial space. Whether it be through public satellite tracking via applications such as Heavens-Above or The High Definition Earth Viewing system’s continuous video feed from the camera attached to the ISS (NASA, "High Definition") – which streams us back an image of our planetary habitat from an Archimedean point of view – we are being encouraged to embrace a kind of digital enculturation of extraterrestrial space. The production of social life outside our own planet has already had many forms, but perhaps can be seen most clearly aboard the International Space Station, presently the only extraterrestrial environment physically occupied by humans. Amongst its many landmark events, the ISS has become a vigorous node of social media activity. For example, in 2013 Chris Hadfield became a Twitter phenomenon while living aboard the ISS; the astronaut gathered over a million Twitter followers, he made posts on Facebook, Tumblr and Reddit, multiple mini-vids, and his rendition of David Bowie’s Space Oddity on YouTube (Hadfield) has thus far been viewed over 26 million times. His success, as has been noted, was not merely due to his use of social media in the unique environment of outer space, but rather that he was able to make the highly technical lives of those in space familiar by revealing to a global audience “how you make a sandwich in microgravity, how you get a haircut” (Potter). This techno-mediation of the everyday onboard ISS is, from a Stieglerian perspective, a gesture toward the establishment of “the relation of the living to its milieu” (49). As part of this process, the new trends and innovations of social media on earth are, for example, continuously replayed and rehearsed in the outer space, with a litany of ‘digital firsts’ such as the first human-sent extraterrestrial ‘tweet’, first Instagram post, first Reddit AMA and first Pinterest ‘pin’ (Knoblauch), betraying our obsessions with serial digital beginnings. The constitution of an extra-planetary milieu progresses with the ability to conduct real-time interactions between those on and outside the earth. This, in essence, collapses all social aspects of the physical barrier and the ISS becomes merely a high-tech outer suburb of the globe. Yet fluid, uninterrupted, real-time communications with the station have only just become possible. Previously, the Iinternet connections between earth and the ISS were slow and troublesome, akin to the early dial-up, but the recently installed Optical Payload for Lasercomm Science (OPAL), a laser communications system, now enables the incredible speeds needed to effortlessly communicate with the human orbital outpost in real-time. After OPAL was affixed to the ISS, it was first tested using the now-traditional system test, “hello, world” (NASA, "Optical Payload"); referencing the early history of digital culture itself, and in doing so, perhaps making the most apt use of this phrase, ever. Open to Beginnings Digital technologies have become vital in sustaining social life, facilitating the immaterial production of knowledge, information and affects (Hardt and Negri), but we have also become increasingly attentive to their materialities; or rather, the ‘matter of things’ never went away, it was only partially occluded by the explosion of social interactivities sparked by the ‘digital revolution’. Within the ongoing ‘material turn’, there have been a gamut of inquiries into the material contexts of the ‘digital’, for example, in the fields of digital anthropology (Horst and Miller), media studies (Kirschenbaum, Fuller, Parikka) and science and technology studies (Gillespie, Boczkowski, and Foot) – to mention only a very few of these works. Outside the globe material things are again insistent, they contain and maintain the terrestrial life from which they were formed. Outer space quickens our awareness of the materiality underpinning the technical apparatus we use to mediate and communicate and the delicate support that it provides for the complex of digital practices built upon it. Social exchanges between earth and its extra-planetary exurbias are made possible through the very materiality of digital signals within which these immaterial interactions can take place. In the pared down reality of contemporary life in outer space, the sociality of the digital is also harnessed to bring forth forms of material production. For example, when astronauts in space recently needed a particular wrench, NASA was able to email them a digital file from which they were then able print the required tool (Shukman). Through technologies such as the 3D printer, the line between products of the social and the creation of material objects becomes blurred. In extra-planetary space, the ‘thingness’ of technologies is at least as crucial as it is on earth and yet – as it appears – material production in space might eventually rely on the infrastructures occasioned by the immaterial exchanges of digital culture. As technical objects, like the 3D printer, are evolving so too are conceptions of the relationship that humans have with technologies. One result of this is the idea that technologies themselves are becoming capable of producing social life; in this conception, the relationships and interrelationships of and with technologies become a potential field of study. We suggest here that the extra-planetary extension of digital cultures will not only involve, but help shape, the evolution of these relationships, and as such, our conceptions and articulations of a future beyond the globe will require a re-positioning of the human and technical objects within the arena of life. This will require new beginnings. Yet beginnings are duplicitous, as Maurice Blanchot wrote – “one must never rely on the word beginning”; technologies have always been part of the human, our rapport is in some sense what defines the human. To successfully introduce the social in outer space will involve an evolution in both the theory and practice of this participation. And it is perhaps through the extra-planetary projection of digital culture that this will come about. In outer space the human partnership with the objects of technology, far from being a utopian promise or dystopian end, is not only a necessity but also a productive force shaping the collective beginnings of our historical co-evolution. Objects of technology that migrate into space appear designed to smooth the ontological misgivings that might arise from our extra-planetary progress. While they are part of the means for producing the social in outer space and physical fortifications against human frailty, they are perhaps also the beginnings of the extraterrestrial enculturation of technologies, given form. One example of such technologies is the anthropomorphic robots currently developed by the Dextrous Robotics Laboratory for NASA. The latest iteration of these, Robotnaut 2 was the first humanoid robot in space; it is a “highly dexterous” robot that works beside astronauts performing a wide range of manual and sensory activities (NASA, "Robonaut"). The Robonaut 2 has recorded its own series of ‘firsts’, including being the “first robot inside a human space vehicle operating without a cage, and first robot to work with human-rated tools in space” (NASA, "Robonaut"). One of the things which mark it as a potential beginning is this ability to use the same tools as astronauts. This suggests the image of a tool using a tool – at first glance, something now quite common in the operation of machines – however, in this case the robot is able to manipulate a tool that was not designed for it. This then might also include the machine itself in our own origins, in that evolutionary moment of grasping a tool or stealing fire from the gods. As an exteriorisation of the human, these robots also suggest that a shared extra-planetary culture would involve acknowledging the participation of technologic entities, recognising that they share these beginnings with us, and thus are participating in the origins of our potential futures beyond the globe – the prospects of which we can only imagine now. Identifiably human-shaped, Robonauts are created to socialise with, and labour together with, astronauts; they share tools and work on the same complex tasks in the same environment aboard the International Space Station. In doing so, their presence might break down the separation between the living and the nonliving, giving form to Stiegler’s hypothesis regarding the ontology of technical objects, and coming to represent a mode of “being” described as “organized inert matter” (49). The robonaut is not dominated by the human, like a hand-held tool, nor is it dominating like a faceless system; it is engineered to be conducted, ‘organised’ rather than controlled. In addition to its anthropomorphic tendencies – which among other things, makes them appear more human than astronauts wearing space suits – is the robonaut’s existence as part of an assemblage of networked life that links technical objects with wet bodies into an animate system of information and matter. While this “heralds the possibility of making the technical being part of culture” (Simondon 16), it also suggests that extra-planetary digital cultures will harness what Simondon formulates as an “ensemble” of “open machines” – a system of sensitive technologies toward which the human acts as “organizer and as a living interpreter” (13). In the design of our extra-planetary envoys we are evolving toward this openness; the Robonaut, a technical object that shares in digital culture and its social and material production, might be the impetus through which the human and technological acquire a language that expresses a kind of evolutionary dialectic. As a system of inclusions that uses technologies to incorporate/socialise everything it can, including its own relationship with technical objects, digital culture in outer space clarifies how technologies might relate and “exchange information with each other through the intermediacy of the human interpreter” (Simondon 14). The Robonaut, like the tweeting astronaut, provides the test signals for what might eventually become points of communication between different modes of being. In this context, culture is collective cumulative memory; the ‘digital’ form of culture suggests an evolution of both technologic life and human life because it incorporates the development of more efficient means of storing and transmitting memory as cultural knowledge, while recognising the experience of both. Social learning and memory will first define the evolution of the Robonaut. Digital culture and the social expressed through technology – toward a shared social life and cultural landscape established in outer space – will involve the conservation, transmission and setting of common patterns that pool a composite interplay of material, neurobiologic and technologic variables. This will in turn require new practices of enculturation, conviviality with technologies, a sharing, incorporation and care. Only then might this transform into a discussion concerning the ontologies of the ‘we’. (Far from) Conclusions Hannah Arendt wrote that technologic progress could not find full expression in “normal” (3) language and that we must constantly be aware that our knowledge, politics, ethics and interactions with regard to technologies are incomplete, unformulated or unexpressed. It could be said then that our relationship with technologies is constantly beginning, that this need to keep finding new language to grasp it means that it actually progresses through its rehearsal of beginnings, through the need to maintain the productive inquisitive force of a pleasant first meeting. Yet Arendt’s idea emerges from a kind of contempt for technology and her implied separation between ‘normal’ and what could be called ‘technical’ language suggests that she privileges the lay ‘human’ tongue as the only one in which meaningful ideas can be properly expressed. What this fails to acknowledge is an appreciation of the potential richness of technical language and Arendt instead establishes a hierarchy that privileges one’s ‘natural’ language. The invocation of the term ‘normal’ is itself an admission of unequal relations with technologies. For a language to develop in which we can truly begin to express and understand the human relationship with ever-changing but ever-present technologies,, we must first allow the entrance of the language of technology into social life – it must be incorporated, learnt or translated. In the future, this might ultimately give technology a voice in a dialogue that might be half-composed of binary code. Digital culture is perhaps a forerunner of such a conversation and perhaps it is in the milieu of outer space that it could be possible to see advances in our ideas about the mutually co-constitutive relationship between the human and technical. The ongoing extra-planetary extension of the digital cultures have the productive potential to sculpt the material and social ambits of our world, and it is this capacity that may precipitate beginnings which will leave lasting imprints upon the prospects of our shared post-human futures.

Introduction Curation-related discourses have become widespread. The growing public profile of curators, the emergence of new curation-related discourses and their proliferation beyond the confines of museums, particularly on social media, have led some to conclude that we now live in an age of curation (Buskirk cited in Synder). Curation is commonly understood in instrumentalist terms as the evaluation, selection and presentation of artefacts around a central theme or motif (see O’Neill; Synder). However, there is a growing academic interest in what underlies the shifting discourses and practices. Many are asking what do these changes mean (Martinon) now that “the curatorial turn” has positioned curation as a legitimate object of academic study (O’Neill). This article locates an exploration of the curatorial turn in journalism studies since 2010 within the shifting meanings of curation from antiquity to the digital age. It argues that the industry is facing a Foucauldian moment where the changing political economy of news and the proliferation of user-generated content on social media have disrupted the monopolies traditional news media held over the circulation of knowledge of current affairs and the power this gave them to shape public debate. The disruptions are profound, prompting a rethinking of journalism (Peters and Broersma; Schudson). However, debates have polarised between those who view news curation as symptomatic of the demise of journalism and others who see it as part of a wider revival of the profession, freed from monopolistic institutions to circulate a wider array of knowledge and viewpoints (see Picard). This article eschews such polarisations and instead draws on Robert Picard’s argument that journalism is in transition and that journalism, as a set of professional practices, is adapting to the age of curation but that those traditional news providers that fail to adapt will most likely decline. However, Picard’s approach does not address the definitional problem as to what distinguishes news curating from other journalistic practices when the commonly used instrumental definition can apply to editing. This article aims to negotiate this problem by addressing some of the conceptual ambiguities that arise from wholly instrumental notions of news curation. From “Cura” to the Curatorial Turn and the Age of Curation Modern instrumentalist definitions are necessary but not sufficient for an exploration of the curatorial turn in journalism. Tracing the meanings of curation over time facilitates an expansion of the instrumental to include metaphoric conceptualisations. The term originated in a Latin allegory about a mythological figure, personified as the “cura”, translated literally as care or concern, and who created human beings from the clay of the earth. Having created the human, the cura was charged by the gods with the lifelong care of the human (Reich) and at the same time became a symbol of curiosity and creativity (see Nowotny). “Curators” first emerged in Imperial Rome to denote a public officer charged with maintaining order and the emperor’s finances (Nowotny) but by the fourteenth century the meaning had shifted to that of religious officer charged with the care of souls (Gaskill). At this point the metaphorical associations of creativity and curiosity subsided. Six hundred years later souls had been replaced by artefacts valorised because of their contribution to human knowledge or as a testament to exceptional human creativity (Nowotny). Objects of curiosity and originality, as well as their creators, were reified and curation became the specialist practice of an expert custodian charged with the care and preservation of artefacts but relegated to the background to collect, evaluate and archive artefacts entrusted to the care of museums and to be preserved for future generations. Instrumentalist meanings thus dominated. From the 1960s discourses shifted again from the privileging of a “producer who actually creates the object in its materiality” to an entire set of actors (Bourdieu 261). These shifts were part of the changing political economy of museums, the growing prevalence of exhibitions and the emergence of mega-exhibitions hosted in global cities and capable of attracting massive audiences (see O’Neill). The curator was no longer seen merely as a custodian but able to add cultural value to artefacts when drawing individual items together into a collection, interpreting their relevance to a theme then re-presenting them through a story or visuals (see O’Neill). The verb “to curate”, which had first entered the English lexicon in the early 1900s but was used sporadically (Synder), proliferated from the 1960s in museum studies (Farquharson cited in O’Neill) as mega-exhibitions attracted publicity and the higher profile of curators attracted the attention of intellectuals prompting a curatorial turn in museum studies. The curatorial turn in museum studies from the 1980s marks the emergence of curation as a legitimate object of academic enquiry. O’Neill identified a “Foucauldian moment” in museum studies where shifting discourses signified challenges to, and disruptions of, traditional forms of knowledge-based power. Curation was no longer seen as a neutral activity of preservation, but one located within a contested political economy and invested with contradictions and complexities. Philosophers such as Martinon and Nowotny have highlighted the impossibility of separating the oversight of valuable artefacts from the processes by which these are selected, valorised and signified and what, at times, has been the controversial appropriation of creative outputs. Thus, a new critical approach emerged. Recently, curating-related discourses have expanded beyond the “rarefied” world of museum studies (Synder). Social media platforms have facilitated the proliferation of user-generated content offering a vast array of new artefacts. Information circulates widely and new discourses can challenge traditional bases of knowledge. Audiences now actively search for new material driven in part by curiosity and a growing distrust of the professions and establishments (see Holmberg). The boundaries between professionals and lay people are blurring and, some argue, knowledge is being democratized (see Ibrahim; Holmberg). However, as new information becomes voluminous, alternative truths, misinformation and false information compete for attention and there is a growing demand for the verification, selection and presentation of artefacts, that is online curation (Picard; Bakker). Thus, the appropriation of social media is disrupting traditional power relations but also offering new opportunities for new information-related practices. Journalism is facing its own Foucauldian moment. A Foucauldian Moment in Journalism Studies Journalism has been traditionally understood as capturing today’s happenings, verifying the facts of an event, then presenting these as a narrative that reporters update as news unfolds. News has been seen as the preserve of professionals trained to interview eyewitnesses or experts, to verify facts and to compile what they found into a compelling narrative (Hallin and Mancini). News-gathering was typically the work of an individual tasked with collecting stand-alone stories then passing them onto editors to evaluate, select, prioritise and collate these into a collection that formed a newspaper or news programme . This understanding of journalism emerged from the 1830s along with a type of news that was accessible, that large numbers of people wanted to read and that, consequently, attracted advertising making news profitable (Park). The idea that presumed trained journalists were best placed to produce news appeared first in the UK and USA then spread worldwide (Hallin and Mancini). At the same time as there was growing demand for news, space constraints restricted how much could be published and the high costs of production served as a barrier to entry first in print then later in broadcast media (Picard; Curran and Seaton). The large news organisations that employed these professionals were thus able to control the circulation of information and knowledge they generated and the editors that selected content were able, in part, to shape public debates (Picard; Habermas). Social media challenge the control traditional media have had over the production and dissemination of news since the mid-1800s. Practically every major global news story in 2010 and 2011 from natural disasters to uprisings was broken by ordinary people on social media (Bruns and Highfield). Twitter facilitates a steady stream of updates at an almost real-time speed that 24-hour news channels cannot match. Facebook, Instagram and blogs add commentary, context, visuals and personal stories to breaking news. Experts and official sources routinely post announcements on social media platforms enabling anyone to access much of the same source material that previously was the preserve of reporters. Investigations by bloggers have exposed abuses of power by companies and governments that journalists on traditional media have failed to (Wischnowski). Audiences and advertisers are migrating away from traditional newspapers to a range of different online platforms. News consumers now actively use search engines to find available information of interest and look for efficient ways of sifting through the proliferation of the useful and the dubious, the revelatory and the misleading or inaccurate (see Picard). That is, news organisations and the professional journalists they employ are increasingly operating in a hyper-competitive (see Picard) and hyper-sceptical environment. This paper posits that cumulatively these are disrupting the control news organisations have and journalism is facing a Foucauldian moment when shifting discourses signify a disturbance of the intellectual rules that shape who and what knowledge of news is produced and hence the power relations they sustain. Social media not only challenge the core news business of reporting, they also present new opportunities. Some traditional organisations have responded by adding new activities to their repertoire of practices. In 2011, the Guardian uploaded its entire database of the expense claims of British MPs onto its Website and invited readers to select, evaluate and comment on entries, a form of crowd-sourced curating. Andy Carvin, while at National Public Radio (NPR) built an international reputation from his curation of breaking news, opinion and commentary on Twitter as Syria became too dangerous for foreign correspondents to enter. New types of press agencies such as Storyful have emerged around a curatorial business model that aggregates information culled from social media and uses journalists to evaluate and repackage them as news stories that are sold onto traditional news media around the world (Guerrini). Research into the growing market for such skills in the Netherlands found more advertisements for “news curators” than for “traditional reporters” (Bakker). At the same time, organic and spontaneous curation can emerge out of Twitter and Facebook communities that is capable of challenging news reporting by traditional media (Lewis and Westlund). Curation has become a common refrain attracting the attention of academics. A Curatorial Turn in Journalism The curatorial turn in journalism studies is manifest in the growing academic attention to curation-related discourses and practices. A review of four academic journals in the field, Journalism, Journalism Studies, Journalism Practice, and Digital Journalism found the first mention of journalism and curation emerged in 2010 with references in nearly 40 articles by July 2015. The meta-analysis that follows draws on this corpus. The consensus is that traditional business models based on mass circulation and advertising are failing partly because of the proliferation of alternative sources of information and the migration of readers in search of it. While some of this alternative content is credible, much is dubious and the sheer volume of information makes it difficult to discern what to believe. It is unsurprising, then, that there is a growing demand for “new types and practices of curation and information vetting” that attest to “the veracity and accuracy of content” particularly of news (Picard 280). However, academics disagree on whether new information practices such as curation are replacing or supplementing traditional newsgathering. Some look for evidence of displacement in the expansion of job advertisements for news curators relative to those for traditional reporters (Bakker). Others look at how new and traditional practices co-exist in organisations like the BBC, Guardian and NPR, sometimes clashing and sometimes collaborating in the co-creation of content (McQuail cited in Fahy and Nisbet; Hermida and Thurman). The debate has polarised between whether these changes signify the “twilight years of journalism or a new dawn” (Picard). Optimists view the proliferation of alternative sources of information as breaking the control traditional organisations held over news production, exposing their ideological biases and disrupting their traditional knowledge-based power and practices (see Hermida; Siapera, Papadopoulou, and Archontakis; Compton and Benedetti). Others have focused on the loss of “traditional” permanent journalistic jobs (see Schwalbe, Silcock, and Candello; Spaulding) with the implication that traditional forms of professional practice are in demise. Picard rejects this polarisation, counter-arguing that much analysis implicitly conflates journalism as a practice with the news organisations that have traditionally hosted it. Journalists may or may not be located within a traditional media organisation and social media is offering numerous opportunities for them to operate independently and for new types of hybrid practices and organisations such as Storyful to emerge outside of traditional operations. Picard argues that making the most of the opportunities social media presents is revitalising the profession offering a new dawn but that those traditional organisations that fail to adapt to the new media landscape and new practices are in their twilight years and likely to decline. These divergences, he argues, highlight a profession and industry in transition from an old order to a new one (Picard). This notion of journalism in transition usefully negotiates confusion over what curation in the social media age means for news providers but it does not address the uncertainty as to where it sits in relation to journalism. Futuristic accounts predict that journalists will become “managers of content rather than simply sourcing one story next to another” and that roles will shift from reporting to curation (Montgomery cited in Bakker; see Fahy and Nisbet). Others insist curators are not journalists but “information workers” or “gatecheckers” (McQuail 2013 cited in Bakker; Schwalbe, Silcock, and Candello) thereby differentiating the professional from the manual worker and reinforcing the historic elitism of the professions by implying curation is a lesser practice. However, such demarcation is problematic in that arguably both journalist and news curator can be seen as information workers and the instrumental definition outlined at the beginning of this article is as relevant to curation as it is to news editing. It is therefore necessary to revisit commonly used definitions (see Bakker; Guerrini; Synder). The literature broadly defines content creation, including news reporting, as the generation of original content that is distinguishable from aggregation and curation, both of which entail working with existing material. News aggregation is the automated use of computer algorithms to find and collect existing content relevant to a specified subject followed by the generation of a list or image gallery (Bakker; Synder). While aggregators may help with the collection component of news curation, the practices differ in their relation to technology. Apart from the upfront human design of the original algorithm, aggregation is wholly machine-driven while modern news curation adds human intervention to the technological processes of aggregation (Bakker). This intervention is conscious rather than automated, active rather than passive. It brings to bear human knowledge, expertise and interpretation to verify and evaluate content, filter and select artefacts based on their perceived quality and relevance for a particular topic or theme then re-present them in an accessible form as a narrative or infographics or both. While it does not involve the generation of original news content in the way news reporting does, curation is more than the collation of information. It can also involve the re-presenting of it in imaginative ways, the re-formulating of existing content in new configurations. In this sense, curation can constitute a form of creativity increasingly common in the social media age, that of re-mixing and re-imagining of existing material to create something novel (Navas and Gallagher). The distinction, therefore, between content creation and content curation lies primarily in the relation to original material and not the assumed presence or otherwise of creativity. In addition, curation outputs need not stand apart from news reports. They can serve to contextualize news in ways that short reports cannot while the latter provides original content to sit alongside curated materials. Thus the two types of news-related practices can complement rather than compete with each other. While this addresses the relation between reporting and curation, it does not clarify the relation between curating and editing. Bakker eludes to this when he argues curating also involves “editing … enriching or combining content from different sources” (599). But teasing out the distinctions is tricky because editing encompasses a wide range of sub-specialisations and divergent duties. Broadly speaking, editors are “newsrooms professionals … with decision-making authority over content and structure” who evaluate, verify and select information so are “quality controllers” in newsrooms (Stepp). This conceptualization overlaps with the instrumentalist definition of curation and while the broad type of skills and tasks involved are similar, the two are not synonymous. Editors tends to be relatively experienced professionals who have worked up the newsroom ranks whereas news curators are often new entrants ultimately answerable to editors. Furthermore, curation in the social media age involves voluminous material that curators sift through as part of first level content collection and it involves ever more complex verification processes as digital technologies make it increasingly easy to alter and falsify information and images. The quality control role of curators may also involve in-house specialists or junior staff working with external experts in a particular region or specialisation (Fahy and Nisbett). Some of job advertisements suggest a growing demand for specialist curatorial skills and position these alongside other newsroom professionals (Bakker). Whether this means they are journalists is still open to question. Conclusion This article has presented a more expansive conceptualisation of news curation than is commonly used in journalism studies, by including both the instrumental and the symbolic dimensions of a proliferating practice. It also sought to avoid confining this wider conceptualisation within unhelpful polarisations as to whether news curation is symbolic of a wider demise or revival of journalism by distinguishing the profession from the organisation in which it operates. The article was then free to negotiate the conceptual ambiguity surrounding the often taken-for-granted instrumental meanings of curation. It argues that what distinguishes news curation from traditional newsgathering is the relationship to original content. While the reporter generates the journalistic equivalent of original content in the form of news, the imaginative curator re-mixes and re-presents existing content in potentially novel ways. This has faint echoes of the mythological cura creating something new from the existing clay. The other conceptual ambiguity negotiated was in the definitional overlaps between curating and editing. On the one hand, this questions the appropriateness of reducing the news curator to the status of an “information worker”, a manual labourer rather than a professional. On the other hand, it positions news curators as one of many types of newsroom professionals. What distinguishes them from others is their status in the newsroom, the volume, nature and verification of the material they work with and the re-mixing of different components to create something novel and useful.
