Full textAbstract:
Flexible production is a key element in modern industrial manufacturing. Autonomous mobile manipulators can be used to execute various tasks: from logistics, to pick and place, or handling. Therefore, autonomous robotic systems can even increase the flexibility of existing production environments. However, the application of robotic systems is challenging due to their complexity and safety concerns. This paper addresses the design and implementation of the autonomous mobile manipulator OMNIVIL. A holonomic kinematic design provides high maneuverability and the implemented sensor setup with the underlying localization strategies are robust against typical static and dynamic uncertainties in industrial environments. For a safe and efficient human–robot collaboration (HRC), a novel workspace monitoring system (WMS) is developed to detect human co-workers and other objects in the workspace. The multilayer sensor setup and the parallel data analyzing capability provide superior accuracy and reliability. An intuitive zone-based navigation concept is implemented, based on the workspace monitoring system. Preventive behaviors are predefined for a conflict-free interaction with human co-workers. A workspace analyzing tool is implemented for adaptive manipulation, which significantly simplifies the determination of suitable platform positions for a manipulation task.

A new kinematic design of a parallel spherical wrist with actuator redundancy is presented. A special feature of this parallel manipulator is the arrangement of co-axial actuators which allows unlimited rotation about any axis inside a cone-shaped workspace. A detailed kinematic analysis has shown that actuator redundancy not only removes singularities but also increases workspace while improving dexterity. The structure optimization has been performed with a global dexterity criterion. Using a conditioning measure, a comparison with a non-redundant structure of the same type was performed and shows that a significant improvement in dexterity has been obtained.

The purpose of this research is to explore the relationship between gender and job satisfaction, as well as its factors. The case study was conducted among academic and administrative staff at a university environment, to identify factors contributing to job satisfaction and their importance for female and male employees. Overall, there were 102 returned questionnaires and 20 interviews with academic and administrative employees.
The relationships between gender and job satisfaction factors were found for specific factors such as personal workspace and job security. T-tests identified statistical significance for differences in satisfaction with personal workspace, relationship with co-workers, and support for training and development factors. Besides, more females are concerned with flexibility at work than males.

This study intends to investigate indoor air quality of kitchen such as velocity, temperature, humidity and air contaminant (carbon monoxide and carbon dioxide). Test results show that workspace local temperature is up to 49.6°C at 12:50 due to the workload increased at the diner peak and the largest CO and CO2concentration were 14.8 ppm and 2145 ppm respectively after 2 hours cooking, which are above the acceptance criteria (CO<10ppm and CO2<1000ppm), and it gives serious impact on the staff's physical health. It is necessary to improve indoor air quality through kitchen ventilation.

Purpose Paediatric congenital esophageal atresia surgery typically requires delicate and dexterous operations in a narrow and confined workspace. This study aims to develop a novel robot assisted surgical system to address these challenges. Design/methodology/approach The proposed surgical robot consists of two symmetrical slave arms with nine degree of freedoms each. Each slave arm uses a rigid-dexterous configuration and consists of a coarse positioning manipulator and a distal fine operation manipulator. A small Selective Compliance Assembly Robot Arm (SCARA) mechanism was designed to form the main component of the coarse positioning unit, ensuring to endure large forces along the vertical direction and meet the operational demands. The fine positioning manipulator applied the novel design using flexible shafts and universal joints to achieve delicate operations while possessing a high rigidity. The corresponding kinematics has been derived and then was validated by a co-simulation that was performed based on the combined use of Adams and MATLAB with considering the real robot mass information. Experimental evaluations for the tip positioning accuracy and the ring transfer tasks have been performed. Findings The simulation was performed to verify the correctness of the derived inverse kinematics and demonstrated the robot’s flexibility. The experimental results illustrated that the end-effector can achieve a positioning accuracy within 1.5 mm in a confined 30 × 30 × 30 mm workspace. The ring transfer task demonstrated that the surgical robot is capable of providing a solution for dexterous tissue intervention in a narrow workspace for paediatric surgery. Originality/value A novel and compact surgical assist robot is developed to support delicate operations by using the dexterous slave arm. The slave arm consists of a SCARA mechanism to avoid experiencing overload in the vertical direction and a tool manipulator driven by flexible shafts and universal joints to provide high dexterity for operating in a narrow workspace.

This research explores how the open-plan office space in the Pikiran Rakyat Bandung head office influences the visual privacy preferences of the editorial staff. The aim is to find out what visual privacy is needed by the employees and the factors that might cause visual privacy disturbance on the employees of the open-plan office. The research observed several workstations with the potential of visual privacy disturbances, namely workstations that: a) is back-to-back with the walkway, b) is located at a walkway junction, c) is directly adjacent to the door, d) is adjacent to joint work facilities, e) is facing other coworkers, and f) is close to other co-workers on the right or left side. The research method was descriptive qualitative, using field observations and interviews to collect data. The result shows that: a) The interior settings of the workspace in open office space adjacent to coworkers both on the right side and left side are the most dominant factors that cause disruption to employees in visual privacy; b) Characteristics of employee’s task which need solitude condition influence visual privacy preferences the most, especially in the work layout (monitor). Thus, office space planning in an open office space at the Bandung People's Mind headquarters should consider the need for visual privacy by a) Rearranging the interior settings of the workspace with the ideal amount of workspace, b) Adding physical barriers between workspaces, and c) Arranging centralized shared work facilities for employees in open office space, hence minimalize disturbance from the conducted activities.

IntroductionSpace matters. We read space like we read people’s faces. Space is an instrument of collaboration and innovation. At the University of Michigan’s Institute for Clinical and Health Research (MICHR), a team was created to creatively and economically enhance our operating space into a flexible workspace that supports privacy, innovation, creativity, and most important, a culture of collaboration.MethodsThe team used a human-centered design process to creatively engage the staff at large into analyzing our existing space, identifying latent needs, proposing solutions, generating feedback, and economically building the rethought process.ResultsThe redesigned workspace embraces the differences among MICHR’s teams while encouraging collaboration and teamwork and keeping costs at a minimum. It has resulted in a flexible space that includes co-located teams, spaces dedicated to different work goals, an open area for collaboration, quiet zones for focused work, and better wayfinding.ConclusionsThrough our Rethink Space project, we hope to have demonstrated that, by initiating the project internally and by engaging the users of the space themselves in an empathetic, visual, and human-centered way, a space redesign can be undertaken economically while also leading to improved levels of employee and team satisfaction.

Application of hybrid robotics is a continuously developing field, as hybrid manipulators have demonstrated that they can combine the benefits of serial structures and parallel mechanisms. In this paper, a novel 5-degree-of-freedom hybrid manipulator is designed. The structure of this manipulator and its kinematics analysis are presented. An innovative closed-form solution was proposed to address the inverse kinematics problem. Additionally, the validity of the closed-form solution was verified via co-simulation using MATLAB and ADAMS. Finally, the reachable workspace of this manipulator was obtained for further optimizing the structure and motion control.

Full textAbstract:
Human–robot collaboration poses many challenges where humans and robots work inside a shared workspace. Robots collaborating with humans indirectly bring difficulties for accomplishing co-carrying tasks. In our work, we focus on co-carrying an object by robots in cooperation with humans using visual and force sensing. A framework using visual and force sensing is proposed for human–robot co-carrying tasks, enabling robots to actively cooperate with humans and reduce human efforts. Visual sensing for perceiving human motion is involved in admittance-based force control, and a hybrid controller combining visual servoing with force feedback is proposed which generates refined robot motion. The proposed framework is validated by a co-carrying task in experiments. There exist two phases in experimental processes: in Phase 1 , the human hand holds one side of the box object, and the robot gripper of the Baxter robot automatically approaches to the other side of the box object and finally holds it; in Phase 2 , the human and the Baxter robot co-carry the box object over a distance to different target positions.

Full textAbstract:
Technologies that support co-located collaboration must not only provide a shared workspace, but also support collaboration. From an observational study, some collaboration problems were identified in groups of people working in a system with a Tangible User Interface. Some of these problems could be identified and prevented with the support of Coaching System. This system encourages interactions between group members through Social Interventions. To develop a Coaching System, it is necessary to know the cohesion between the members of the group, in order to decide the appropriate Social Interventions. In this paper, a model is proposed to represent the social interactions that occur in a group of people when performing a task. Interactions can be analyzed to determine the degree of cohesiveness of a group and support the collaboration.

Full textAbstract:
Cognitive approaches to motor control typically concern sequences of discrete actions without taking into account the stunning complexity of the geometry and dynamics of the muscles. This begs the question: Does the brain convert the intricate, continuous-time dynamics of the muscles into simpler discrete units of actions, and if so, how? One way for the brain to form discrete units of behavior from muscles is through the synergistic co-activation of muscles. While this possibility has long been known, the composition of potential muscle synergies has remained elusive. In this paper, we have focused on a method that allowed us to examine and compare the limb stabilization properties of all possible muscle combinations. We found that a small set (as few as 23 out of 65,536) of all possible combinations of 16 limb muscles are robust with respect to activation noise: these muscle combinations could stabilize the limb at predictable, restricted portions of the workspace in spite of broad variations in the force output of their component muscles. The locations at which the robust synergies stabilize the limb are not uniformly distributed throughout the leg's workspace, but rather, they cluster at four workspace areas. The simulated robust synergies are similar to the actual synergies we have previously found to be generated by activation of the spinal cord. Thus, we have developed a new analytical method that enabled us to select a few muscle synergies with interesting properties out of the set of possible muscle combinations. Beyond this, the identification of robustness as a common property of the synergies in simple motor behaviors will open the way to the study of dynamic stability, which is an important and distinct property of the vertebrate motor-control system.

Full textAbstract:
Humans and robots are becoming co-workers, both in industrial and medical applications. This new paradigm raises problems related to human safety. To accomplish and solve this issue, many researchers have developed collision avoidance strategies—mainly relying on potential field approaches—in which attractive and repulsive virtual forces are generated between manipulators and objects within a collaborative workspace. The magnitude of such virtual forces strongly depends on the relative distance between the manipulators and the approaching agents, as well on their relative velocity. In this paper, authors developed an intrinsically distributed probabilistic algorithm to compute distances between the manipulator surfaces and humans, allowing tuning the computational time versus estimation accuracy, based on the application requirements. At each iteration, the algorithm computes the human–robot distances, considering all the Cartesian points within a specific geometrical domain, built around humans’ kinematic chain, and selecting a random subset of points outside of it. Experimental validation was performed in a dynamic and unstructured condition to assess the performance of the algorithm, simulating up to six humans into the shared workspace. Tests showed that the algorithm, with the selected hardware, is able to estimate the distance between the human and the manipulator with a RMSE of 5.93 mm (maximum error of 34.86 mm).

AbstractCurrent asynchronous (e. g., email) or synchronous (e. g., video-conferencing) communication methods in the workspace can be obtrusive and fail to mimic spontaneous interpersonal communication. This can cause difficulties in forming close relationships among working colleagues. To examine this problem, we conducted a needs assessment study consisting of an online survey, a focus group, and a co-design session to gather a set of system requirements and metaphors as a base for future system designs. Based on the results, we designed two metaphor-based ambient tangible systems to support awareness among working colleagues:AwareCupsandAwareHouse. Furthermore, we evaluated these systems in a short field study with 22 participants and found that both systems are highly intuitive and easy to use. We discuss the solution space for metaphor-based tangible awareness systems and the effects of the outcomes on the potential increase of awareness among colleagues.

<p class="Abstract">Co-working space is an alternative workspace, which offers
different concept and spirit from offices in general. Co-working space is aimed to workers who need a flexible
place and time to collaborate and expand their network. As a social space, co-working
space cannot be separated from the
growth of millennial generation as freelancers, who entered the labor market
since 2000’s. This research is aimed to analyze the consumption practice of co-working
space’s user. There are two chosen
users of co-working space located in
Jakarta that are used as subjects in this research by interview. Using Henri
Lefebvre’s theory about production of space,
this research shows that: 1) there is a shift in meaning of work, from duty-ethic to fun-ethic 2) millennial generation’s competence of information and
communication technology makes it possible for them to do creative work with no
limit of time. Flexibility becomes lifestyle. Blurred line between work time
and leisure time is a privilege that can’t be owned by other workers. In the
end, it is a strategy to create a social distinction, that co-working space’s users are different from workers in
general. <o:p></o:p></p>

With the increase of the weight and volume of building components, the collaborative working of multiple cranes is necessary when one crane cannot meet the lifting requirement sometimes. This paper is devoted to model and analyze a type of cable parallel manipulators for multiple cranes (CPMMCs). The CPMMCs have better lifting capability than a single crane and can be applied in complex lifting tasks. Kinematics and dynamics of the end-effector of the CPMMCs are studied and the reachable workspace is carried out additionally. Considering the requirements of large output torque, large motion scope etc. the hydraulic drive mode is adopted. The bond graph method is applied for the analysis of hydraulic systems. Subsequently, the AMESim models for the hydraulic systems are constructed. The performance of the CPMMCs and the accuracy of the models are verified by co-simulation under working conditions.

Monoxide (CO) bonds with blood are 200 times stronger than oxygen bonds with blood. When inhaled CO will be absorbed through the lungs following the blood circulation and binds to haemoglobin to form HbCO in the tissues which will block the entry of oxygen needed by the body. The purpose of this study was to determine the relationship of air CO levels with oxygen saturation (SpO2) in officers in Terminal Type B of South Kalimantan Province. This type of research is analytically using a cross-sectional design with a sample of 24 people. Data collection was carried out by interview, observation, CO measurement and SpO2 examination with Pulse Oximetry. The results showed that there was a relationship between air CO levels and the SpO2 of terminal officers with a significance value of 0.0025 (sig. <0.05). Even though the air CO level in the field is still far below the threshold, but the SpO2 level of officers is not healthy, the smoking habits of terminal officers cause it in the workspace, and the field with the number of cigarettes smoked as many as 11-20 cigarettes per day. There are more than 20 sticks per day, so prevention efforts are needed by providing and using PPE (Personal Protective Equipment) for terminal staff in the form of masks and striving for the terminal team to stop smoking.

The continuous improvement in the growth rate of urbanization in Indonesia is causing an increased need for work, limited residential land, and high prices for residential development in urban areas. This phenomenon has an impact on the low occupancy rate for the millennial generation and this makes developers offer co-living space which is considered capable of solving the problem of accommodation and its use as a living space is becoming increasingly popular in recent times. Therefore, this study aimed to identify the factors influencing the formation of habitual occupancy among millennials in the co-living space of Indonesia. The process involved using a survey method with online questionnaires to collect data from the study population which consisted of the millennial generation with a sample size of 190 respondents. The data obtained were processed using exploratory multivariant statistics to show the relationship between the latent variables used in forming habitual behavior in shared living. The results showed 10 factors which constitute the living behavior in co-living space and they include public facilities, social, place attachment, feeling of satisfaction, environment, intrinsic, extrinsic, group development, economy, and workspace availability.

In this paper, we studied the maximum inclination angles in the human shoulder girdle and compared them with the motion abilities of the humanoid robotic shoulder proposed in 1,2) We found that the extreme inclination angles of the human shoulder girdle are different when the arm is constantly stretched downward or when the arm executes an inclination co-planar to the girdle's motion. The humanoid robotic shoulder fulfills the range of the maximum inclination angles in the second type of motion but its workspace is obviously too small for the first type of motion. We also measured the working cone of the human arm and found that central axis of the human arm working cone is about 60° inclined in the horizontal plane.

An effective method is proposed to establish explicit relationships between the end effector co-ordinates and the active and passive joint variables. A simulation of the 2-Delta robot on a C.A.D. Robotics system will also be presented. This simulation will allow us to validate the cohesion of our calculations, and to show the workspace depending on the mechanical limits on passive joints variables. Finally, an approach is proposed to study the influence of small clearances of the passive joint on the precision of the position and rotation of the effector. This approach is based on a concept similar to that of Yoshikawa's manipulability.

Full textAbstract:
In this paper, two novel approaches to unmanned underwater vehicle path planning are presented. The main idea of the first approach, referred to as Constrained Optimisation (CO) is to represent the free space of the workspace as a set of inequality constraints using vehicle configuration variables. The second approach converts robot path planning into a Semi-infinite Constrained Optimisation (SCO) problem. The function interpolation technique is adopted to satisfy the start and goal configuration requirements. Mathematical foundations for Constructive Solid Geometry (CSG), Boolean operations and approximation techniques are also presented to reduce the number of constraints, and to avoid local minima. The advantages of these approaches are that the mature techniques developed in optimisation theory which guarantee convergence, efficiency and numerical robustness can be directly applied to the robot path planning problem. Simulation results have been presented.

Recently, robotic sensor systems have gained more attention annually in complex system sense strategies. The robotic sensors sense the information from itself and the environment, and fuse information for the use of perception, decision, planning, and control. As an important supplement to traditional industrial robots, co-bots (short for co-working robots) play an increasingly vital role in helping small and medium-sized enterprises realize intelligent manufacturing. They have high flexibility and safety so that they can assist humans to complete highly repetitive and high-precision work. In order to maintain robot safe operation in the increasing complex working environment and human–computer intelligent interactive control, this paper is concerned with the problem of applicant accuracy analysis and singularity avoidance for co-bots. Based on the dynamic model with load and torque sensors, which is used to detect the external force at the end of the robot, this paper systematically analyzes the causes of singularity phenomenon in the robot motion control. The inverse solution is obtained by analytical method and numerical method, respectively. In order to ensure the smooth and safe operation in the whole workspace, it is necessary for a robot to avoid singularity. Singularity avoidance schemes are utilized for different control tasks, including point-to-point control and continuous path control. Corresponding simulation experiments are designed to verify the effectiveness of different evasion schemes, in which the advantages and disadvantages are compared and analyzed.

Augmented reality (AR) technology can support collocated work enabling users to flexibly work with digital objects while still being able to use the physical space for coordination. With most of current research focusing on remote AR collaboration, less is known about collocated collaboration in AR, particularly in relation to interpersonal dynamics between the collocated collaborators. Our study aims at understanding how shared augmented reality facilitated by mobile devices (mobile augmented reality or MAR) affects collocated users' coordination. We compare the coordination behaviors that emerged in a MAR setting with those in a comparable fully physical setting by simulating the same task -of the shared physical dimension for participants' ability to coordinate in the context of collaborative co-creation. Namely, participants working in a fully physical setting were better able to leverage the work artifact itself for their coordination needs, working in a mode that we term artifact-oriented coordination. Conversely, participants collaborating around an AR artifact leveraged the shared physical workspace for their coordination needs, working in what we refer to as space-oriented coordination. We discuss implications for a AR-based collaboration and propose directions for designers of AR tools.

Air is an important component for the survival of living things, especially humans. However, air quality has decreased due to pollution. The harmful elements that enter the atmosphere are Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Particulates (PM10), and Ozone (O3). Noise is defined as unwanted sound or sound so that it disturbs and endangers health. Sources of noise are divided into moving and stationary noise sources. The method used in this research is grab sampling by installing an air sampler impinger to capture particles or pollutants as well as taking noise data using a simple method with a Sound Level Meter with a reading every 5 seconds within 10 minutes for one measurement. The results showed that the air quality in residential and workspace areas was still within quality standards. The noise level in residential areas is still acceptable, but the noise level in the production room surpasses the acceptable limit.

Gas or liquefied petroleum gas (LPG) is a chemical substance resultant from petroleum and could be dangerous in industrial places or those that deal with this substance. Gas leakage causes many health issues. So, to prevent such catastrophes and in order to maintain a clean air environment, the workspace atmosphere should be frequently monitored and controlled. The proposed monitoring gas leakage detector system is based on Internet of Things (IoT) technology. NodeMCU ESP8266 Wi-Fi is used to be the microcontroller for the whole system. The combustible gas sensor (MQ2) is used in order to detect the presence of methane (CH4) and carbon monoxide gas (CO). MQ2 sensor will detect the concentration of the gas according to the voltage output of the sensor and the ESP8266 will send the data reading from the gas sensor to Blynk IoT platform over an IOS phone; data visualization is done using Thingspeak IoT Platform. Besides, a fan will immediately work upon the leakage occurs along with an alarming buzzer.

Large interactive displays can provide suitable workspaces for learners to conduct collaborative learning tasks with visual information in co-located settings. In this research, we explored the use of these displays to support collaborative engagement and exploratory tasks with visual representations. Our investigation looked at the effect of four factors (number of virtual workspaces within the display, number of displays, position arrangement of the collaborators, and collaborative modes of interaction) on learners’ knowledge acquisition, engagement level, and task performance. To this end, a user study was conducted with 72 participants divided into 6 groups using an interactive tool developed to support the collaborative exploration of 3D visual structures. The results of this study showed that learners with one shared workspace and one single display can achieve better user performance and engagement levels. In addition, the back-to-back position with learners sharing their view and control of the workspaces was the most favorable. It also led to improved learning outcomes and engagement levels during the collaboration process.

Ability to learn human context in an environment could be one of the most desired fundamental abilities that a robot should have when sharing a workspace with human co-workers. Arguably, a robot with appropriate human context awareness could lead to a better human–robot interaction. In this paper, we address the problem of learning human context in an office environment by only using 3D point cloud data. Our approach is based on the concept of affordance-map, which involves mapping latent human actions in a given environment by looking at geometric features of the environment. This enables us to learn the human context in the environment without observing real human behaviors which themselves are a nontrivial task to detect. Once learned, affordance-map allows us to assign an affordance cost value for each grid location of the map. These cost maps are later used to develop an active object search strategy and to develop a context-aware global path planning strategy.

AbstractThis paper examines some aspects of physical-digital workspaces, focusing on multi-user, multi-touch technologies and how different workspaces impact collaboration. We introduce the concept of globally collaborative work. We chose to use case studies completed by groups of students in an engineering course to test different workspace modalities: the use of a large multi-touch table top in conjunction with a multi-touch board (vertical), the use of tablets with the multi-touch board, and finally the multi-touch board alone. The evaluation criteria are based on modes of interaction which emerge during globally collaborative work sessions: individual work, communication, coordination, cooperation and collaboration. We hypothesized that the workspaces would influence collaborative activity, expecting to see higher rates of collaboration in the table top environment than in the other two modalities studied. However, results showed less co-building and more cooperative work, as students divided their work and later attempted to negotiate a coherent product built on individual contributions. Lastly, we share a few design recommendations based on these results.

Full textAbstract:
In light of future work challenges, actual human resource management (HRM) needs to be redesigned, including long-term development, regeneration, and renewal of human resources, passing from consuming to developing human resources by incorporating the concept of sustainability. Thus, sustainable HRM is seen as an extension of strategic human resources, presenting a new approach to human resource management. The labor market is constantly changing, atypical work acquiring a significant relevance, especially in these current times of coronavirus crisis restrictions. In Romania, promoting the law of teleworking transformed labor flexibility into a topic of interest, and became an increasingly vital requirement for employment and a motivating factor for Romanian employees. In such a context, this paper aims to investigate the link between employee development and worktime and workspace flexibility as relevant characteristics of sustainable HRM, job satisfaction and job performance among Romanian employees in order to identify how to redesign HRM in the face of “future work” challenges. Additionally, the paper aims to examine the impact of different types of flexibility—contractual, functional, working time, and workspace flexibility—in order to highlight the relevance of employee development and employee flexibility as important aspects of sustainable HRM in increasing the overall level of employee job satisfaction. In order to make this possible, an “employee flexibility composite indicator,” which takes into account different types of flexibility, has been developed using feedback from Romanian employees, which was gathered by a national representative survey using multiple correspondence analysis. Furthermore, the impact of both individual and employee flexibility on overall level of job satisfaction has been quantified using binary logistic regression models. Within the research, there is a particular focus on the impact of new types of workspaces (flex office, co-working, total home office, partial home office—FO, CW, HOT, HOP) on job performance, job satisfaction, organizational performance, professional growth and development, social and professional relationships, and personal professional performance as well as on the overall level of work motivation. The empirical results revealed that these new types of workspaces are highly appreciated by employees, generating a growing interest among them. Partial home working, the mix between working from home and working in a company’s office, has been considered an optimal solution in increasing organizational performance, social and professional relationships, learning and personal development, and the overall level of work motivation. The results of the multiple correspondence analysis highlighted a medium level of flexibility among those Romanian employees interviewed, with only one third of them exhibiting high levels of flexibility. The empirical analysis of logistic regression analysis pointed out the role of functional flexibility, working time, and workspace flexibility along with the flexibility composite indicator in increasing the level of job satisfaction in employees. Therefore, if the challenge is to redesign the actual human resource management in order to include the concept of sustainability, attention needs to be on a combination of employee development-flexible time and flexible places, leading to an increase in both employee job satisfaction and organizational performance as important outcomes of sustainable HRM.

With rapid urbanization, massive amount of energy is required to compensate the electricity usage thus calls for a need to Malaysian government issuing standard MS1525:2014 for temperature settings in office buildings to meet energy efficiency goal. In co-sharing spaces, personal thermal comfort is often not met due to the different thermal sensation at different location inside office rooms. This study was conducted at four postgraduate office spaces with cooling mode in university campus located at Kuala Lumpur to evaluate the occupant’s thermal sensation. We used different set-point temperature of air conditioning ranging from 18.0°C to 28.6°C. The indoor thermal variables such as air temperature, globe temperature, relative humidity, and air velocity are measured at each respondent’s workspace and 200 responses were recorded from ten subjects. The mean value of thermal sensations votes is -0.4 and were within comfort range. 76% of responses voted ‘neutral’ humidity sensation as occupants have adapted to humid condition in Malaysia. The comfort operative temperature found in this study is 24.9°C which indicates that the minimum recommended temperature for energy conservation did not deprive occupants from comfort.

Sinergi Co-Working a place that is a collaboration of a workspace and cafe, which is located at Jl. Cendrawasih No.32b, Demangan, Yogyakarta. All inventory recording activities at this cafe are still being done manually. Starting from recording the incoming and outgoing raw materials and goods. As a result, the inventory flow is not good enough to cause inventory to become damaged or production failure. Users who can access bookkeeping are many. This also results in frequent errors in recording, reports that are not detailed or lacking and inventory becomes obstructed and accumulation occurs in the warehouse. The research objective was to create an inventory system for raw materials and goods using the First In First Out method to answer and solve problems that occurred. This research makes inventory recording better and more systematic so that the operational flow of materials and goods is always fresh. Using such a system improves the flow of inventory. And a good display will help employees or users increase their knowledge of product knowledge. The inventory system that has been successfully built was tested on 10 respondents with 11% less agreeable results. The system is needed, but it is still considered lacking by respondents. In the inventory flow that will be in the actual field. It could be that the system runs well but in the field, it doesn't, due to employee negligence. Then the biggest result is Agree 49%. The inventory system is correct and appropriate to answer all existing problems.

Full textAbstract:
Pb–Zn deposits supply a significant proportion of critical metals, such as In, Ga, Ge, and Co. Due to the growing demand for critical metals, it is urgent to clarify the different types of Pb–Zn deposits to improve exploration. The trace element concentrations of sphalerite can be used to classify the types of Pb–Zn deposits. However, it is difficult to assess the multivariable system through simple data analysis directly. Here, we collected more than 2200 analyses with 14 elements (Mn, Fe, Co, Ni, Cu, Ga, Ge, Ag, Cd, In, Sn, Sb, Pb, and Bi) from 65 deposits, including 48 analyses from carbonate replacement (CR), 684 analyses from distal magmatic-hydrothermal (DMH), 197 analyses from epithermal, 456 analyses from Mississippi Valley-type (MVT), 199 analyses from sedimentary exhalative (SEDEX), 377 analyses from skarn, and 322 analyses from volcanogenic massive sulfide (VMS) types of Pb–Zn deposits. The critical metals in different types of deposits are summarized. Machine learning algorithms, namely, decision tree (DT), K-nearest neighbors (KNN), naive Bayes (NB), random forest (RF), and support vector machine (SVM), are applied to process and explore the classification. Learning curves show that the DT and RF classifiers are the most suitable for classification. Testing of the DT and RF classifier yielded accuracies of 91.2% and 95.4%, respectively. In the DT classifier, the feature importances of trace elements suggest that Ni (0.22), Mn (0.17), Cd (0.13), Co (0.11), and Fe (0.09) are significant for classification. Furthermore, the visual DT graph shows that the Mn contents of sphalerite allow the division of the seven classes into three groups: (1) depleted in Mn, including MVT and CR types; (2) enriched in Mn, including epithermal, skarn, SEDEX, and VMS deposits; and (3) DMH deposits, which have variable Mn contents. Data mining also reveals that VMS and skarn deposits have distinct Co and Ni contents and that SEDEX and DMH deposits have different Ni and Ge contents. The optimal DT and RF classifiers are deployed at Streamlit cloud workspace. Researchers can select DT or RF classifier and input trace element data of sphalerite to classify the Pb–Zn deposit type.

The article deals with the concept of the flexible office as a modern type of workspace designed to provide a variety of places and ways to work and identifies the main design techniques used to implement the concept and philosophy of "flexibility” on the example of the interior design of the co-working centre. The purpose of the article is to define the specifics of implementing the flexible office concept in the context of the co-working center design. Research methodology. A complex of general scientific methods and methods of contemporary art history are applied: generalisation and systematisation of materials on the problems of flexible office design; the system analysis method, which facilitated the study of the characteristic features of the flexible office design as elements of a single whole; the method of structural and functional analysis, which revealed features of the flexible office as one of the most popular types of working space; classification method through which the basic principles of the flexible office concept are established and analysed through the prism of the co-working centre design. Scientific novelty. The main trends of flexible office design are theorised; the specifics of the design approach to the formation of co-working centre space are examined as an example of the embodiment of the basic principles of flexible office design. Conclusions. The study of design approaches for the co-working centre space formation proved their compliance with the main principles of flexible office design – smart space architecture, functional adequacy and ergonomic perfection of the furniture, inclusiveness, acoustics, air conditioning, natural components, maintaining the possibility of changing lighting level, colouring scheme aimed at maintaining and enhancing attention and ability to work.
It is found that although the main planning type in the co-working centre is universal, combining open and cubicle types, their design suggests adherence to the concept of a flexible office.
The key elements of flexible office design have a huge impact on the working atmosphere of the co-working center and are used by designers to support efficient work. Main design solutions to optimize the co-working center space in line with the flexible office philosophy, which includes adaptation to the residents’ needs and establishing communications, are the main driving force behind the workflow.
The concept of the flexible office in the context of the specifics of a co-working center supports the trend towards the transformation of activities and behavior, provides the resident with the space that best meets his needs and the ability to choose where he wants to work and/or rest at any moment.
The co-working center design forms a unique communicative space for inspiration, creativity, and reflection by creating interiors that inspire and reflect the visual trends of the socio-cultural space of the beginning of the 21st century. Stimulation of creative and cognitive work patterns following the main trends of the flexible office concept contributes to increased work capacity.
The subject-spatial environment of the flexible office creates a characteristic emotional state and intensifies communication in the co-working center, becoming one of the factors in mobilizing the creative process and enabling residents to make bold professional decisions.

Rationale: Depression is commonly co-morbid with vision impairment yet often remains undetected and therefore untreated. This study aimed to use a theoretical framework of behaviour change to identify issues surrounding the implementation of depression screening in a low vision rehabilitation service in Australia. Evidence-based strategies to address barriers are highlighted.Method: Twenty-two low vision rehabilitation staff, who had undergone training in using a depression screening tool, took part in semi-structured interviews covering 11 theoretical domains of behaviour change. Interviews were audio-taped and transcribed. Two researchers independently coded the transcripts from each interview and assigned a score to determine whether the transcript showed evidence of poor, partial, or good implementation within each domain.Results: Major barriers to depression screening included lack of time, face-to-face contact with clients and private workspace. Limited referral options and concerns about the efficacy of referrals to primary care services were highlighted. Negative emotions anticipated during depression screening (e.g., feeling awkward, uncomfortable or nervous) and concerns that depression screening would have a detrimental impact on the client and client relationship were also barriers to depression screening in practice.Conclusions: Enhancing knowledge and skill around depression screening is not sufficient to create change. Practical-based training needs to be combined with the development of strong referral pathways to ensure implementation success.

Abstract The paper aims to study cybersecurity correlations with the knowledge economy, focusing on its challenges in this new age of economy. The relevance of the cybersecurity concept is sustained by the academic literature that shows its important role in the business environment, where disruptive changes will become the norm. In the digital age the disruptions are happening frequently which gives organizations less time to manage the change and the fact that they are almost constrained to develop new strategies to answer the challenges of the changing business environment. The knowledge economy has evolved and with that, new concepts began to appear out of necessity and the need to secure the dynamic environment of knowledge management systems. Considering the unprecedented access to information and advancements in conducting academic research, in the present landscape of the knowledge economy and cybersecurity domain, new methods are available to structure and examine a body of literature. The text mining and scientific mapping analysis conducted with VOSviewer software version 1.6.18 is allowing us to identify meaningful insights about the knowledge economy concept, such as the (1) existing research gaps, at least on cybersecurity challenges in the knowledge economy and the (2) the research interests seen for the time period between 2019 and 2021. To achieve this, a database derived from Web of Science’s core collection has been used, and the text mining based on term co-occurrence analysis contributed to a deeper understanding of current and future workspace dynamics.

Collaborative robots cooperate with humans to assist them in undertaking simple-to-complex tasks in several fields, including industry, education, agriculture, healthcare services, security, and space exploration. These robots play a vital role in the revolution of Industry 4.0, which defines new standards of manufacturing and the organization of products in the industry. Incorporating collaborative robots in the workspace improves efficiency, but it also introduces several safety risks. Effective safety measures then become indispensable to ensure safe and robust interaction. This paper presents the review of low-level control methodologies of a collaborative robot to assess the current status of human–robot collaboration over the last decade. First, we discuss the classification of human–robot collaboration, architectures of systems and the complex requirements on control strategies. The most commonly used control approaches were presented and discussed. Several methods of control, reported in industrial applications, are elaborated upon with a prime focus on HR-collaborative assembly operations. Since the physical HRC is a critical control problem for the co-manipulation task, this article identifies key control challenges such as the prediction of human intentions, safety, and human-caused disturbances in motion synchronization; the proposed solutions were analyzed afterwards. The discussion at the end of the paper summarizes the features of the control systems that should be incorporated within the systematic framework to allow the execution of a robotic task from global task planning to low-level control implementation for safe and robust interactions.

The comparison of selected soil mechanical parameters measured on plastic soils under remoulded and structurally intact conditions may provide an opportunity to assess soil structural quality on a regional or even broader scale. This study was conducted to determine: (i) if existing pedotransfer functions developed for southwestern Ontario soils could be used outside this physiographic region, and (ii) if key mechanical parameters were sensitive to a range of land use conditions that are likely to influence soil structural quality. Soil profiles were sampled in natural (forested or grassland), agricultural and pipeline workspace areas (land use variable) located in southwestern Ontario, eastern Ontario, Alberta and Texas (mineralogy variable). Slurry consolidation and uniaxial compression tests were conducted on remoulded and structurally intact samples, the resulting void ratio-log stress [e(logσ')]data were fitted to linear or nonlinear model equations, respectively, and several key mechanical parameters were derived. The effective stresses at the liquid and plastic limits could not be adequately estimated for soils with smectitic mineralogy using existing pedotransfer functions because of the absence of a significant relationship with organic carbon content. The difference between void ratio intercepts for remoulded and structurally intact soils (e*1kPa–e0) was found to be a suitable indicator of physical soil quality because of the convergence of remoulded and structured compression lines in e(logσ') co-ordinates. Severely overconsolidated soils were identified when the (e*1kPa–e0) variable exceeded 0.40. This threshold also corresponded to soil conditions that could limit plant growth. Key words: Compression, consolidation, pedotransfer function, soil quality, Atterberg limits, remoulded, structured, pipeline, woodland

The Co-working space and Food Hall in jakarta is a facility that designed based on the needs and development of creative economy business that growing rapidly but there are no adequate facilities and support at this time. So the main design problem is how to create space that can convey identity and become an icon of the development of creative economy in Jakarta. Besides the needs for business developers to work productively, this project also raises special design issues, namely how to create social space and green space to support more productivity of users. The design approach used is a general approach and a symbolyc approach using intangible metaphor, taking from the main nature of business startup developers namely innovation. Then, the deepening of space characters is chosen to look at the completion of the needs from different workspaces according to users needs. This facility is different from the workspace in general because it prioritizes intercation space (interaction sapce) and also green space, but does not ignore the privacy needed by each user. Office and Co-working space designs are also supported by facilities such as cafetaria, gathering room, meeting room, and retail. AbstrakRuang Kerja Bersama dan Balai Boga di Jakarta merupakan fasilitas yang didesain didasari oleh kebutuhan serta perkembangan bisnis ekonomi kreatif yang kian pesat namun belum ada fasilitas yang memadai dan mendukungnya saat ini. Sehingga masalah desain utama adalah bagaimana menciptakan ruang yang dapat menyampaikan identitas dan menjadi ikon perkembangan ekonomi kreatif di Jakarta. Selain itu adanya kebutuhan para pengembang bisnis untuk bekerja secara produktif, maka proyek ini juga mengangkat masalah desain khusus yaitu bagaimana menciptakan ruang sosial dan ruang hijau untuk mendukung produktivitas lebih dari user. Pendekatan desain yang digunakan adalah pendekatan umum dan pendekatan simbolik dengan menggunakan intangible metaphore, mengambil dari sifat utama para pengembang bisnis pemula yakni Inovasi. Kemudian, pendalaman karakter ruang dipilih untuk mencermati penyelesaian kebutuhan ruang-ruang kerja yang berbeda sesuai dengan kebutuhan pengguna. Fasilitas ini berbeda dengan ruang kerja pada umumnya karena mengutamakan ruang interaksi (interaction space) dan juga ruang hijau, namun tidak mengabaikan privasi yang dibutuhkan setiap pengguna. Desain kantor dan ruang kerja bersama juga didukung dengan fasilitas seperti cafetaria, ruang berkumpul, ruang rapat, dan juga retail.

Purpose – The purpose of this paper is to explore hybrid work spaces, combining open-plan, team-based offices with virtual work and leadership, in relation to the main leadership and team challenges virtual project environments encounter. Design/methodology/approach – In a review of virtual team literature, virtuality is defined and its main challenges to project leadership are identified. Based on the literature, several semi-structured interviews with project team managers within telecom and IT-consultancy were conducted. Using an exploratory approach, the authors introduce some new leadership concepts and functional benefits of open-plan offices important for virtual project environments. Findings – The findings suggest that project managers encounter several new kinds of challenges while leading virtual projects. Co-location of the project team during certain stages in open-plan, team-based offices may meet some of these challenges. The authors claim that spatial arrangements and their embodied subjective experiences make an impact on the effectiveness of virtual project teams. Research limitations/implications – This paper develops new conceptual thinking of how office facilities may contribute to productive virtual project teams. Further empirical studies in other settings are needed to generate generalizable findings. Practical implications – The paper discusses and provides arguments for real estate and facility managers, as well as project and team leaders, for the importance of open-plan offices for virtual project teams. Originality/value – The paper combines and benefits from different discussions on workspaces, virtual team and leadership. Furthermore, the paper introduces the notion of spatial leadership beyond the mainstream leader-centric approach to point out the importance of physical workspace of virtual teams and how the workspaces can perform leadership functions.

Full textAbstract:
Background: Due to the COVID-19 pandemic, in 2020, many employees were required to work from home (WFH). During this WFH period, some employees encountered health issues related to sprains and neck or back pain owing to poor working conditions at home. As the WFH trend may continue over a prolonged period, the underlying causes and solutions to ergonomic issues must be addressed to reduce injuries. This study aims to identify the ergonomic issues encountered when working from home and suggests several solutions to minimise these issues. Methods: A qualitative ethnographic methodology was adopted. This study used focus group discussion and the panellists were among experts from the fields of higher education, healthcare, human resources (HR), and ergonomics patient in Malaysia. The most common ergonomic issues identified were based on diagnoses and observations in previous studies. Results: The panellists agreed on ergonomics issues, comprising the use of unergonomic chairs, incorrect sitting postures, irregular arrangement of key objects, improper reach distances of the laptop/keyboard/mouse, poor desk designs, footrest absence, distortion/noise, poor lighting, and poor work environment. Over time, WFH ergonomics issues may lead to burnout, carpal tunnel syndrome or other cumulative trauma disorders, high blood pressure, and stress on the cervical spine and neck. The proposed solutions include a complete WFH ergonomics and wellness checklist for employees and employers, webinar sessions on WFH ergonomics, meet-up sessions with ergonomics or HR experts, workspace rentals for co-workers, implementation of the 20-20-20 rule and job-sharing practices, and the involvement of employers or the government in procuring ergonomic equipment for WFH employees. Conclusions: This is a preliminary study and the researchers are exploring the root causes of WFH ergonomics issues and proposed solutions. While previous studies have examined workplace ergonomics, this study focuses on WFH ergonomic issues and solutions during the ongoing pandemic.

Full textAbstract:
Purpose The purpose of this paper is to further explore the relationship between new product development project teams and their workspace regarding the impact of the physical (space variety, indoor environmental quality, large meeting room, workstation) and sociotechnical environments (project commitment, IT environment) on their creativity and effectiveness. Design/methodology/approach The authors gathered data on an enterprise’s ten multidisciplinary teams operating in diverse workspaces by four means: over 40 interviews and four months of observation, secondary data and a survey with 645 responses. Findings For teams co-located on site and abroad, employees express that proximity in open space is paramount even considering the augmented density. The relationship between team effectiveness and team creativity is strong and bidirectional (correlationβ = 0.40****), but the patterns of relationship between these two variables and certain dimensions of the physical and sociotechnical environment are different. There is a positive and direct impact on team effectiveness, but to a lesser degree on creativity which, in turn, positively influences team effectiveness. Moreover, creativity intervenes (mediator variable) between project commitment, satisfaction with large meeting rooms and the IT environment on their relationship with team effectiveness. When the authors added a direct link between the variables and team effectiveness, the model explains 47.1 per cent of the variance. Research limitations/implications The scope of the data is somewhat limited by the time that the company and its teams could allocate to this paper. Practical implications The arrangement of space reinforces employees’ sense of belonging to their team as measured by project commitment which along with satisfaction with the large meeting rooms and IT environment influence both team effectiveness and creativity. Managers could consider these three elements as levers for action. Space variety (or balanced layout) is also a way to support team creativity. Originality/value Even if open spaces are frequently used, the literature on creative spaces is dedicated mainly to an individual. This paper delivers some results and evidence on the concrete and simultaneous impacts of the workspaces on creativity and effectiveness of multidisciplinary new product development (NPD) team.

Full textAbstract:
The features of digital tools and educational platforms are considered. It is noted that the Google Workspace for Education package has all the necessary functionality for the implementation of distance learning in full. The use of Digital Tools Google in the educational process at Lutsk National Technical University has been analyzed in accordance with the ranking method. It was determined that teachers most often use Google Drive to store information in cloud storage and co-edit documents (84 % of respondents), and Google Meet – to organize lectures remotely (72 % of respondents). Most teachers consider it possible to transfer lectures and consultations to a remote format, but it is advisable to conduct practical classes in a classroom layout, which involves face-to-face communication between teachers and students and the use of university educational equipment.
A functional scheme of organization of training with the help of digital tools Google has been suggested. Its use is recommended both for personal purpose in the design of the discipline, and for conducting trainings for improving teaching skills. Digital applications for organizing the educational process, preparing educational material, conducting lectures, practical classes and evaluating academic achievements have been specified. The final stage is reflection, as a result of which the teacher makes changes to the organization and content of the educational process as for certain discipline, and the student can adjust the personal level of knowledge and skills.
A SWOT analysis of the use of digital technologies in higher education institutions was carried out (on the example of Lutsk National Technical University). The number of identified strength indicators according to the outlined criteria is much greater, which is a sign of the viability and prospects of digital technologies in the implementation of the educational process in the surroundings of today’s challenges. The weak side is the lag in the digital competence of teachers from the rapid development of digital technologies. The main threats in the present and future are related, in our opinion, to two factors. The first is financial, since insufficient state funding of educational institutions significantly complicates the widespread use of licensed software products. The second factor is internal, personal, due to the low motivation of teachers (especially older ones) to develop and improve e-teaching skills.

<p>Surakarta City is designated as National Activity Center (PKN) on the National Spatial Plan (RTRWN) in the development of the creative economy sector. The determination is reinforced by Bekraf Developer Day 2017 and the Economic Census of the Central Bureau of Statistics which shows that Surakarta has more than 1250 creative workers. 65.75% of them have no place to work, so they do their work at home and or cafe. Problems that arise are how to design facilities and comfortable workspace so that the creative workers can make presentations and discussions with colleagues without being disturbed by the noise of other cafe visitors, or by family activities at home. In order to connect between start-up and creative workers, and to create a comfortable workspace to improve productivity and creativity of its users, is required collaborative working space (office) for creative industry workers and start-up in Surakarta City. The design of collaborative working space is done by collecting primary and secondary data through interviews, observation, precedent study, book literature study, local regulations, articles, and news. The data sets are then analyzed and synthesized to produce the concept of the space character criteria and the concept of the shape and appearance of the space which is then transformed into a collaborative working space design that supports the productivity and creativity of its users in Surakarta.</p>

Advanced mechanics is the sphere that arrangements with the introduction, usage, and manipulate of robots as well as tangible complaint and facts handling. In the approaching years, those advances will update people and human sporting activities. These robots can be utilized for any undertaking, however they are currently being used in sensitive conditions to identify bombs and cripple exceptional bombs, further to different matters. Mechanical generation is a place of technology and designing that joins mechanical designing, electrical designing, software engineering designing, and other designing disciplines. "Robot" is gotten from "robota," that's a slave or restricted work in Czech. Robots are given errands to finish, and they may do as consisting of thought they had been slaves. The expression "robotic" was first of all utilized in 1992 by way of Czech creator Karel Capek in his introduction of Rossum's Universal Robots (R.U.R). He guarantees that a robotic is a device with human-like expertise. Robots are likewise a worry and are step by step becoming a chunk of human life by way of supporting people in their professional and person lives in addition to shielding them from situations that may mean gambles, disquiet, redundancies, and different pessimistic feelings. Consequently, a robot operating with a selected stage of freedom might be an incredibly complicated electromechanical design whose sensible portrayal requests modern method. With the development of various technologies, the volume of tasks carried out by robots has increased, making it appealing for machines to augment human abilities and replace people with robots in temperamental and difficult situations. Robots addressing the future need to be visible as having human beauty on the subject of their plan, information, crafty, and responsiveness to finish responsibilities in human-like methods and to distinguish a actual and secure co-interest amongst human beings and robots. The main aim of industrial robot manipulator is to accomplish the desired position in the given workspace. In the present work direct kinematics mechanism is used to achieve the desired purpose. The objective of the work is to generate the end-effector trajectory for movement and to validate the same by using DH parameter. The trajectory with point to point uninterruptedness motion is the output of the robot programme associated with robot simulation model. This provides the creativity of work to satisfy the required objective. The paper also focuses to help the research scholar preparing the mathematical model for forward kinematics of customized robot for industrial application. Keywords: Robot, Simulation, DH parameter, end effector Manipulator, Direct Kinematics
