Carbon emission has been considerably higher in India in the last few decades. The greenhouse gases increased to an imaginary volume, a major contributor to global warming. Chennai is one of India’s large cosmopolitan cities, contributing more Gross Domestic Product (G.D.P.) and carbon to the atmosphere. The infrastructure sector is always a booming sector in and around Chennai, which requires more construction materials. In turn, the construction of new buildings expands the city with a large area of urban and suburban Chennai, where I.T. division, automobile division, and industrial estates are available. Hence, this study deals with the carbon emission of a residential building constructed with conventional materials in and around Chennai. So, one can estimate the emission of carbon by the conventional building, which leads to global warming and climate change.

Abstract- Arabian came to Indonesia to trade and spread Islam in Indonesia. They came by sea or river. Then they stayed and grew a family with locals on an area. That area became a settlement in a form of a village that known as Arabian Village. One of the famous Arabian Villages is Al-Munawar Arabian Village in Palembang. Al-Munawar Arabian Village is the oldest village in Palembang. This village is still preserve its relics and culture nowadays. One of its remaining relics is eight buildings that decided as heritage buildings. These 8 buildings have their own unique hundreds of year historical background. Three buildings out of eight buildings are picked as object of research.These buildings are land house. These houses adapted Palembang architectural style, which is pyramid house. Land house has “kekijing” in front of its house. Kekijing is a floor with ± 30-40cm terraces. Each step of floor illustrates the depth of faith. The division of land house room follows the division of Islamic residential space. The second building is stone house with Indian architectural style. The wall thickness of this house is ± 37cm. Stone house has an increase of ± 60 cm from ground level. The floor material uses tiles imported directly from Italy. The division of stone house room also follows the division of Islamic residential space. The third building is greenhouse. Greenhouse is a residential home that has changed its function to islamic school with the same shape. This house consists of two floors, the first floor uses brick wall and the second floor uses wooden wall. The division of greenhouse room doesn’t follow the division of Islamic residential space because the building is not a residential house anymore.It’s important to study the cultural heritage buildings in this village. Considering the number of villages and traditional buildings that forgotten because of the modernization. Furthermore, there are few abandoned traditional houses and changed its shape and material became more modern.The purpose of this study is to know the shape, room and the order of the house in Al-Munawar Arabian Village on the Palembang Musi River bank.This is so that traditional buildings in the village will not extinct and become learning materials for all people.The method used is qualitative method. If judged based on the purpose of the research is descriptive research. The data collecting technique are literature study, field observation and interview to the head of neighborhood in the village. This research shows that style of a building and the material that used on the objects of research are different. In addition, the division of residential space such as stone house and greenhouses are still using the division of Islamic residential space, while the greenhouse is no longer. Key Words: Arabic village Palembang, Al-Munawar village, form, space and order.

Elements in accordance with a certain proportion and spatial arrangement constitute the microstructure of the building materials, which lead to a specific property and function in the macro. From the perspective of element chemistry, we divide common building materials into three categories: silicon-based building materials, carbon-based building materials and iron-based building materials. Then, with the knowledge of valence electron structure and electronic configuration, we systematically expound the three-element building materials system. According to that division mode, we explain the microstructural causes and macroscopic properties of the three-element building materials system through the valence bond theory, so as to provide references for the development and application of building materials.

THE SELECTION OF RESIDENTIAL BUILDING CONSTRUCTION MATERIALS USING ANALYTICAL HIERARCHY PROCESS METHODSThe selection of building materials is important in the planning process of housing construction because it will affect the quality of the building and the determination of the selling price of a building. so that an appropriate method is needed in making decisions to determine the specifications of the material to be used. The purpose of this study is to obtain efficient building materials both in terms of price and quality. so that they can support the concept of housing. The concept of housing buildings in this study uses a minimalist concept. The material limitations that will be determined in this study are materials for roof coverings, floor coverings, ceilings, window sills, and doors. The material selection process uses a analysis hierarchy process method with material selection criteria including price, specifications, design, and durability. Each criterion uses three alternatives as a comparison. Data collection was obtained through experts in a housing company with an expert as the head of the planning division. The results of data processing were obtained for the roof covering materials using concrete tiles, floor coverings using granite, ceilings using kalsiboard, window sills using aluminum, and doors using the solid wood material. This research is expected to be useful, especially for construction business actors in determining building materials.

Considerable energy resources are consumed in the production of building materials, during construction and installation works, for operation with current and major repairs, reconstruction, dismantling, utilisation and recycling. As a rule, these energy resources are non-renewable, therefore, for energy saving purposes, it is necessary to take into account the total energy consumption of capital construction facilities during their life cycle. The authors have proposed the structure of a relational database of building materials energy intensity to calculate energy costs. The proposed database contains a list of building materials and energy intensity values at all stages of the life cycle. The novelty of the database is the division of materials by building elements (replaceable, non-replaceable). The article presents fragments of energy intensity calculation of the apartment building life cycle in the Ivanovo city using the proposed database.

Full textAbstract:
The prefabricated building course is a highly theoretical and practical specialized course with strong professionalism and extensive teaching contents. The teaching of prefabricated concrete structures is a significant link in prefabricated building construction and an important direction of cultivating talents applied to prefabricated building construction. Previous teaching features single teaching models, focuses on teaching materials, and highlights theoretical teaching, resulting in students’ low learning initiatives and poor practical ability. In order to improve the teaching effect and students' practical ability, Building Information Modeling (BIM) simulation technology was integrated into the teaching and practice of the prefabricated building courses. Then, the three-stage (guidance of real-scene cases, practical operation based on division of project work, and drawing cross-review) course teaching approach was proposed. With the construction of a prefabricated concrete structure in Hefei Metro of China as an example, students were asked to perform component modeling, assembly, and construction simulation via BIM. Results show that the teaching contents are completed, and the teaching effect is evidently strengthened. Students’ abilities to understand, analyze and practice actual engineering problems are evidently improved, and their problem-solving and practical ability in the aspect of prefabricated buildings is cultivated.

The article analyzes current problems and successful practices of implementing lean technologies at Russian enterprises. The purpose of the presented research work is to develop relevant mechanisms, search for tools and technologies with the help of which the mentioned problems (general and specific) can be overcome. The novelty of the research lies in the justification of the transition to a new paradigm of resource-saving management and adaptation of project management and business analysis tools to the projects of lean technology implementation. To investigate the trends in the formation of a new management paradigm based on the active involvement of resource-saving tools, such general scientific methods as analysis of scientific and specialized literature, synthesis, logical and analytical methods were used. Materials of internal reporting of the enterprises of the machine-building division of Rosatom State Corporation are used in the work. The main problems of implementing lean technologies at Russian enterprises are formulated and ranked. The list of enterprise management techniques in accordance with the new management paradigm is presented, as well as their capabilities to improve the efficiency of management decisions. The importance of digital technologies for ensuring the effectiveness of resource-saving projects is substantiated. An approximate strategic map for nuclear power engineering enterprises, based on the balanced scorecard methodology, in the implementation of lean decisions is developed. The most effective projects of enterprises of the machine-building division of the State Atomic Energy Corporation ROSATOM were identified, which can become benchmarking objects for scaling experience among enterprises of other divisions of the State Corporation, as well as for enterprises of other industries and spheres of activity. Despite the rather high degree of development of the problem of lean technology implementation, new realities form specific factors that can make the previous scientific and practical results irrelevant. Further research of this topic should be carried out on the basis of analyzing the dynamics of the external environment leading to fluctuations in the industry and regional markets.

Full textAbstract:
The carbon emission at the embodied phase is a complex combination, extending the life cycle of the building, defining the process of the embodied phase scientifically and finding out the direct and indirect carbon emission sources in the embodied phase. Building materials have the characteristics of “low carbon surface, hidden high carbon.” Emission factor calculation method is used to establish carbon emission model for building materials. Considering the effect of design optimization on the carbon emissions of the whole life cycle of the building, a low carbon level system is set up to optimize the target of low carbon design. In the construction phase, the carbon emission sources, emission boundary, and calculation model are determined according to the subdivisional engineering division method. Through a series of process decomposition, the total amount of carbon emissions at the embodied phase can be obtained, and the carbon emission quota list at the embodied phase can be compiled to provide technical support for the carbon trading mechanism of the building.

Full textAbstract:
A novel method and description of creating diversified complex original building forms roofed with a number of transformed folded shell units developed on the basis of a novel reference polyhedral network and arranged according to a reference surface with the negative Gaussian curvature is presented. For that purpose, specific reference polyhedral networks is are defined as a complex material deliberately composed of many regular tetrahedrons that are arranged regularly to obtain original attractive complex general building forms. The proposed method is a significant extension of the previous method for shaping roof structures with the positive Gaussian curvature and fills existing gaps in current scientific knowledge. The extended method enables the designer to significantly increase the variety of the created complex shell roof forms and plane-walled folded elevation forms of buildings and to define the shapes of their rod structural systems. It allows one to overcome the existing significant geometric and material limitations related to shape transformations of nominally flat rectangular folded steel sheets into different shell forms. The developed extension is based on formation of a set of properly connected tetrahedra as a material determining different (a) inclination of elevation walls to the vertical, and (b) distribution of many individual warped roof shells in accordance with the properties of a regular surface with negative Gaussian curvature. A number of the adopted specific sets of division coefficients (parameters) is used for determining the entire network and its complete tetrahedra. The presented description makes it possible to adopt appropriate assumptions and data and then employ the innovative method to obtain the expected characteristics of the unconventional building form shaped. The presented three different special forms created with the help of the novel method and the appropriately selected diversified values of the division coefficients of pairs of the vertices of a polyhedral reference network, a polygonal eaves network and points of a reference surface confirm the innovative scientific nature of the obtained results. The method has to be computationally aided due to the complexity of mathematical operations and the need to visualize the designed forms.

Wall insulation material can save a lot of wall materials, improve the performance of the wall insulation, save resources, and reduce environmental pollution, which is a new material for interior and exterior wall insulation. In order to study the insulation performance of insulation material, according to the construction process of insulation material, we design the multi-layer insulation wall structure. In order to verify the insulation effect of energy saving, we use the FLUENT software to do numerical simulation on the wall insulation effect, and establish the heat transfer equation of the radiation and solid. We use the CAD software to design large building model, and use GAMBIT to carry on the grid division, finally get the 2D and 3D temperature distribution by means of numerical calculation. Through the finding of thermal efficiency and energy-saving efficiency, insulation wall can significantly improve the energy performance of buildings, which provides technical support to study the energy saving and environmental protection of building.

Considering the vast areas of building rooftops and the fast development of solar utilization technologies, this paper aims to analyze the regional adaptability of solar roof utilization technologies for buildings in China. All provinces and cities in China are divided into 13 zones based on their economic development, thermal climate division, and availability of solar energy resources. Over 100 buildings are investigated, and the information of 28 buildings is analyzed to finally identify 18 typical building types. A new evaluation method is developed for both solar heating systems and solar PV. An adaptability index is developed considering the energy conservation, environment effect, and economy benefit of the systems. The developed method is used to evaluate the solar utilization technologies applied on the 18 buildings across 13 zones. The result show that the average adaptability index values for solar thermal technology and solar PV technology are 2.54 and 1.63, respectively. The solar heating system has a shorter payback time than the solar PV system for most regions of China and therefore is more favored. Recommendations on supporting policies and measures are given for policy makers with an aim to promote the utilization efficiency of building roofs. This paper provides references for the selection and application of relevant solar utilization technologies on building roofs.

The problem of assessing the possible relative errors of the technical characteristics of building materials when testing samples of the correct geometric shape has been solved. The work is based on the theory of errors and on the method of linearization of functions of random variables. The technical characteristics of the materials are determined by the equations of indirect measurements through the input parameters, directly measured during the tests with known level of accuracy. Linearization of the equations of indirect measurement allowed to obtain dependences for determining the standard and probable relative errors of determining the average density, humidity, water absorption and compressive strength of building materials. Samples of the correct geometric shape of the following types are considered: cube, parallelepiped, circular cylinder. The input values of the obtained formulas are the size and weight of the samples, as well as the destructive force during compression. The accuracy of direct measurement of these values is determined by the values of division of the corresponding measuring instruments. The obtained formulas give possible relative errors of indirect measurements of the analyzed technical characteristics corresponding to the given two-way security level. The use of the obtained formulas allows you to reasonably choose the means for measuring the input parameters that provide the necessary accuracy of the results of determining the technical characteristics with the maximum ease of performing the measurements. The method for assessing the accuracy and the choice of measuring instruments for measuring the size and mass of samples is illustrated by an example of determining the average density of a mortar based on the results of testing cubic samples of different sizes. The results of the study can be used in the experimental determination of the analyzed technical characteristics of building materials of other types, as well as extended to assess the accuracy of other technical characteristics, which are determined by indirect methods.

This paper analyzed sustainable principles of vernacular architecture in Bosnia and Herzegovina featured in the Svrzo’s house complex in Sarajevo, which can serve as an example that can be utilized in contemporary architecture. An energy-efficiency analysis was performed by using DesignBuilder software. The aim was to investigate whether the building design, building’s envelope materialization, and spatial organization comply with today’s energy-efficiency standards and if such principles can be applied in contemporary design. The calculation of the energy demands for heating and cooling showed that the division of the house in winter and summer quarters is an energy-efficient approach that could be transposed into contemporary architecture. The calculations also showed that the materialization of the building envelope of the winter quarter is not energy efficient enough to be used in modern constructions, but the positive aspects of the building envelope materialization such as the use of natural, local materials with good heat capacity are important elements which could serve as guidelines for the materialization of contemporary buildings. Therefore, a new materialization was proposed on the basis of these principles. The calculations showed that the analyzed winter quarter became energy-efficient while maintaining sustainable principles borrowed from vernacular architecture.

Full textAbstract:
The division of Germany after the war led to the former Preussischer Staatsbibliothek (PSB) being split between the Deutsche Staatsbibliothek (DSB) in East Berlin and the Staatsbibliothek Preussischer Kulturbesitz (SBPK) in West Berlin. Following the country's unification, the collections are being reunified in one institution, the Staatsbibliothek zu Berlin, which will be the biggest library in Germany. Both buildings will continue to be used, since neither is large enough to hold the entire collection, both are architecturally significant, and a new building is out of the question. Reintegrating the post-war collections is much less of a problem than the treatment of post-war acquisitions of the two libraries. Large numbers of books (many of them lacking in other major Germany libraries) are duplicated, and it is difficult to achieve a sensible allocation of materials between the buildings. It has been decided to use the older building (DSB) for holdings up to 1955, for consultation only, while the other building (SBPK), which dates from 1978, will house material from 1956 and serve as a lending library. The catalogue sittuation is equally complex. The DSB had a complete record of the pre-war collection of printed books, but the major part of the collection was either in West Berlin or lost; on the other hand, in the west, where 1.7m. volumes of PSB's holdings were concentrated, the SBPK had to start without any catalogue at all. The aim is now to carry out a complete retrospective conversion of all the varied existing catalogues within the next seven years. To add to these complications, the entire older building is being restored to acceptable standards and the former central reading room is being reconstructed; during the lengthy process a storage building is having to be rented. The greatest challenge of all, however, is the integration of staff.

Architecture built in materials colloquially named ?natural? represents one of the most autonomous and most iconic branches of building practices with high ecological considerations (i.e. ?green building?). However, specific character of this architecture, its broad, consistent and coherent approach has seldom been assessed. This research pinpoints broadest conceptual, social and political positions of Natural Building movement - an informal movement. Conditions are determined in which these positions have been formed, together with reasons for which these practices have been ignored in scopes of dominant architectural discourses. Special attention is given to cultural and geographical origins (North America?s northwestern coast and its high arid continental Southwest), to integration of ethical, esthetical and lived experience, and finally to transformations of specialization, authorship and division of labour. Closing parts of the paper also offer examination and illustration of general range of explored phenomena. For this aim two specific architectural approaches are analyzed: Oregon Cob and Earthship, as well as findings and illustrations from construction of small experimental building constructed by the author in Bosnia and Herzegovina.

A strong character can be seen in the form of traditional house buildings that contain philosophical values. Residential buildings in the village of Pinggirpapas consist of three building masses bound in a Tanean or courtyard. Research with the title Identification of Traditional Residential Structures in Pinggirpapas Village, Sumenep Regency aims to recognize the structural parts of traditional residential building construction that still show traces of authenticity. The study uses descriptive rational-qualitative methods that are descriptive and exploratory, and in the selection of building samples, the purposive sampling method is used. The parameter used as a reference in this study is the suitability of secondary data (theory) with the building's empirical conditions. Data analysis was performed based on the division of building structures consisting of the lower, middle, and upper structures. The results showed that traditional houses in Pingirpapas village had a variety of structures ranging from Pandemen (foundations), tana' structures (floors), Canggha structures and Sasaka Ageng (columns), and structures to Ata (roofs). The construction of a traditional house building is made with a knock-down system to move from one place to another. The three-building masses use a combination of natural materials. Teak wood for the overall frame of the building (building and roof frame). A chunk of coral reefs for building footings and clay tile from Palembang for roofing.

This article is an insight into interdisciplinary topics in the field of civil engineering, morphology, architecture, mechanics, and computer programming. A novel method for shaping unconventional complex roofs in which regular folded units transformed into various shells are used as a complex substitute material is proposed. The original method’s algorithm for building systems of planes defining diversified polyhedral networks in the three-dimensional space by means of division coefficients of the subsequently determined vertices is presented. The algorithm is based on the proportions between the lengths of the edges of the reference network, the location and shape of the ruled shell units included in the designed complex roof structure, so it is intuitive. The shell units are made up of nominally flat folded sheets transformed effectively into shell forms whose static-strength properties are controlled by geometric quantities characteristic of ruled surfaces. The presented original approach to the shaping of the shell roof structures determining specific complex building forms allows us to go beyond the limitations related to the orthotropic structure of the folded roof sheeting and the shape transformations.

Background radiation involves the measure of the level of ionizing radiation present in the environment at a particular location. This research seek to generate data of the natural background radiation level of some selected Sections at Kabba College of Agriculture, using RadEye G20 survey meter. A total of 15 sections of the College were randomly selected and the background radiation dose rate of the sections were measured. The indoor dose rate ranged from (0.09 – 0.13) 𝜇Sv/yr, while the outdoor dose rate ranged from (0.07 - 0.10) 𝜇Sv/yr. The indoor annual effective dose were observed to be greater than the outdoor annual effective dose in all the College Sections measured. The lowest total annual effective dose 0.75 𝑚𝑆𝑣/𝑦𝑟 was found at the Academic staff block. The highest total annual effective dose of 1.09 𝑚𝑆𝑣/𝑦𝑟 was found at the livestock building, this might be due to the high-altitude nature of the area and the rocky materials used in the construction of the building. The highest total annual effective dose of the study area was slightly above the recommended limit of 1.0 𝑚𝑆𝑣/𝑦𝑟. The result obtained from this research may not constitute immediate health risk to the staff and student of the college

Introduction. The article presents a technology of erecting of high-rise building's frame structures made of B60-B100 classes high-strength concretes. This technology includes a complex of processes and considers a number of special features, the most significant of which are connected with the specific character of high-strength concretes and concreting climatic conditions.Aim. To determine the main requirements for the technology of concreting and parameters of curing the monolithic structures of high-rise buildings made of B60-B100 classes high-strength concretes, including at winter periods, at the various stages of their erection.Methods and materials. Studies were carried out on the effect of hardening temperature variations from +5 to +50 °С on the hardening kinetics of B60, B80, and B100 classes concretes. Based on the 15-year experience of the “Moscow-City” construction, the mix proportions of high-strength concretes were optimized, as well as the main technological parameters of concreting and curing the frame structures located at an altitude of up to 370 m were analyzed and summarized.Results. The mix proportions of B60-B100 classes concretes of high-workability and self-compacting mixtures with a cement consumption of 350–480 kg/m3 was optimized using standard materials and MB-type organomineral modifiers. The performed study revealed a regularity between the strength and the temperature-temporal parameter of concrete curing, which is applicable for a preliminary assessment of strength characteristics in high-strength concrete structures on the basis of their temperature measurement results. A systematic approach to concrete curing and the maintenance of building structures as a whole with the vertical division of a high-rise building into four temperature zones led to a reducing the probability of thermal cracks appearance.Conclusions. According to the results of the study, the proposed complex of technological solutions concerning compositions and properties of concrete mixtures and concretes, the technology of concreting, as well as the methods of heating and curing the concrete of structures at the various stages of their erection ensures thermal resistance to cracks at the early stage of concrete hardening, as well as the high quality and assigned rates of construction.

The fundamental aim of this study is to demonstrate the positive consequences of the COVID-19 pandemic while everyone else is talking about COVID-19's adverse effects. Researchers collected data through FGD (Focus Group Discussion) via an internet platform from April 2021 to June 2021. FGD was conducted with final-year undergraduate students from Bangladesh's Sylhet division. We purposively selected 20 students who have good knowledge about the consequences of COVID-19 and who were voluntarily involved at the university's different social clubs. According to this study, COVID-19 has positive impacts on people's life. People spent crucial time with their families, explored their interests, developed a range of new skills, and appreciated the need for sanitation, hygiene, and social separation. Nature recovers energy, and greenhouse gas emissions are significantly reduced to protect the ecosystem. Among other notable positive effects, people build religious learning's in conjunction with crime reduction notions. Researchers study a particular division (Sylhet) of a country, which may differ from that of other cultures and countries. As a result, generalizing the research findings is complex; more research in different divisions of Bangladesh, countries, and cultures is required. The study outcomes are intended to assist the community in building positive psychology to confront the covid-19 and establish a new normal and a guideline for dealing with any impending pandemic. To the best of our knowledge, this is one of the most comprehensive studies on the positive effects of covid-19, as well as a guideline for dealing with any pandemic that may occur in the near future.

Full textAbstract:
Transparent design is a reverse space processing method in architectural design that involves partially or completely removing the original division of space, thereby making the entire space more diverse. The application of transparent design methods mainly includes the processing of two-dimensional and three-dimensional spaces, and it involves aspects like building entities, design spaces, design materials, and building structures. Transparent design is a popular form of modern architectural design. It transforms the space and reflects the beauty of the space, allowing light, sight, and air to freely blend throughout the space. At the same time, architectural design is also consistent with the idea of “form follows function” advocated by contemporary architecture, so it has been gradually growing in popularity in architectural design. This article presents a detailed analysis of transparent design, including the types of transparent design, structural model design in transparent design, and the application strategies of transparent design in architecture.

The emergence of new types of structures and construction technologies related to them became the impetus for the search for new forms of buildings and structures and the development of a new understanding of space. Technical and economic calculations show that the area of coverings in buildings with large hall rooms, as a rule, exceeds the total area of other enclosing structures, and therefore the cost of coverings, taking into account installation work, is of predominant importance in construction estimates. Spatial forms of coverings of hall rooms significantly affect the architectural expressiveness of buildings, and therefore the issue of choosing forms, materials and rational constructive solutions of coverings is extremely relevant.
The most important components of the covering systems of buildings and structures are supporting structures, which have unlimited possibilities of interpretation of forms and materials, can be hidden or open and turn into architectural elements. It is obvious that in the process of designing the coverings of buildings and structures, it is necessary to consider and analyze various options for their constructive solutions.
The article analyzes the types of arches, their classification, the conditions of use as load-bearing structures of building coatings, as well as some problems of their static operation, which are related to the choice of form and conditions of their support and division into structural elements. The authors considered the problems of calculating and designing arches, choosing rational forms of arches that ensure the prevention of loss of their stability from the bending plane and a high aesthetic level. The main principles and methods of construction and static calculation of arches are presented.

This research explores the viability of bamboo as a green replacement for timber in building practices. Bamboo’s advantages lie in its renewability, sustainability, and resilience to disasters, despite possessing mechanical properties similar to timber. The study proposes using Finite Element Analysis (FEA) simulations, a potent instrument for designing and analyzing intricate structures under varying loads. The research explicitly employs FEA simulations to examine the application of bamboo in complex rooftop systems, using two commercial 3D CAD software—Rhino7 and Strand7. Rhino7 is responsible for 3D model creation and the member’s division into minuscule elements, whereas Strand7 is used to assign material properties, establish boundary conditions, carry out simulations, and analyze the outcomes. This research includes case studies of bamboo grid-shell structures and implements the suggested methodology. The study’s objective is to augment the scarce engineering data and to analyze bamboo as a material and the impact it can have on construction. The study’s results underscore the potential of eco-friendly, low-carbon materials, such as bamboo, in the construction industry. It also illustrates the effectiveness of FEA simulation in analyzing elaborate structures.

Classification processes (separation, division, sorting) take an important place in food industry where they are used, in particular, for selection of some fractions of grain raw materials (wheat, barley, rye, corn, sunflower, groats) by form, sizes, density or aerodynamic properties of particles of the material or for removal from grain of pollution particles (soil, sand, stones, metallic shaving). The separation processes are quite wide spread in other branches of economy (in chemical, processing, machine building, building, agricultural, metallurgy enterprises), so a task of improvement of classification processes and equipment for their realization is enough actual. Different installations for mechanical classification with unbalanced, hydraulic pulse, pneumatic, electromagnetic, centrifugal drive have reliable design, provide quite stable and effective working process. By our notion, the main working parameters of the mechanical classification of grain raw materials, that determine its efficiency (productivity, specific energy outlay, quality of phase separation) are the maximal speed of movement of the material particles relatively sieve surface and a maximal effort created by the executive element of the installation in the middle of the processed material. Known differential equations of movement and energy balances for determination of these working parameters are complex and unsuitable for elaboration of the engineering method of design calculation of corresponding equipment. So, there are algebraic dependencies for definition of the main working parameters of the mechanical classification under using of basic drives types presented in the article. On the basis of these dependencies, a simple computer program can be compiled to obtain and analyze graphic diagrams that allow to determine the most efficient drive option.

Women’s empowerment conduces economic growth and is crucial for empowering women. Economic freedom means that people can take economic actions independently. Yet, women remain disadvantaged in developing countries like Pakistan. The current study analyses how economic freedom fosters women’s empowerment in Pakistan. We employed time series data for 1990-2021. We employed an index of women’s empowerment (WEI) and the Women's Business and Law Index (WBLI) for economic freedom. WBLI is based on 8 distinct indicators that include diverse aspects of a woman’s life. After unit root testing, we used the ARDL approach followed by the Bound test. The long and short-run empirics have confirmed the association of women’s empowerment and economic freedom in Pakistan. There is a positive and statistically significant relationship between them. A significant ECT term with a negative sign further confirms the long-run association. Women’s mobility, women’s decision to work, rules and laws for equal pay, legal barriers to marriage for women, women’s decision to work after childbirth, restrictions for registering a business on women entrepreneurs, discrimination in the division of property and regulation for women’s pension are the factors that still impede the absolute economic freedom of women in the society.

This study sought to: (1) identify the types and sources of Non-Timber Forest Products (NTFPs) traded; (2) find the frequencyof the NTFPs trade and (3) identify the challenges in NTFPs trading in the Sunyani Municipality. The survey was carried outfrom February, 2014 to April, 2014 mainly at the Sunyani Central and Nana Bosoma Markets in the Sunyani Municipality. Thetarget population comprised NTFPs collectors (gatherers), sellers and consumers. Respondents were purposively sampled. Atotal of 100 respondents were engaged in this study. The NTFPs were grouped into six categories namely; food, medicine,building materials, packaging materials, artefacts and domestic utensils. Key informants’ interviews were also conducted atthe Sunyani Forest Services Division to triangulate the data already gathered. Statistical Package for Social Sciences was usedto analyze the data obtained. The study demonstrated that domestic utensils (37%), food (33%), medicinal products (12%),packaging materials (9%), artefacts (6%) and building materials (3%) were the types of NTFPs traded in the two market centers.The results also showed that majority of the respondents (77%) harvest their NTFPs from forest lands as against 23% whoharvest from communal lands. A significant proportion of the respondents (52%) traded in above 40 kg of NTFPs and only 4%were seen trading in 10 kg of NTFPs. The study further highlighted that food (28%) and domestic utensils (26%) were regularlybrought to the market centers on weekly basis whilst significant proportions of medicinal products (9%), building materials(3%) and artefacts (4%) were brought to the market venues on monthly basis. Cumbersome permit procedure (40%), increasedmarket demand (15%) and financial constraints (20%) were identified as some of the challenges encountered in NTFPs tradingin the Sunyani Municipality. To ensure strict monitoring and sustainability of the resource, there is the need for sensitizationprogramme on the importance of NTFPs in rural livelihood and why their conservation is vital in meeting the needs of thepresent generation whilst not undermining their potential in supplying the needs of future generations.

Wijayaperkasa Indah is a manufacturing company engaged in the processing of logs into semi-finished and finished wood materials and is included in the wood building goods industry. Human resource development applied at PT. Wijayaperkasa Indah is through training and promotion. There are obstacles in the implementation of the training in the form of employee indiscipline in participating in the training and the lack of employee awareness of the importance of the training provided so that employees are not enthusiastic in participating in the training so that many employees do not attend even though employees who attend training properly will be rewarded in the form of promotions. Employees are not disciplined in attending training because the training is not in accordance with the need to work more efficiently and effectively according to company standards so that the results of wood products produced by the production division of PT. Wijayaperkasa Indah still has high product damage. This product damage indicates that the work skills in the production division have stagnated so that the company's management develops human resources to improve employee skills through training.

Symmetrical Frequency Division Multiple Access (OFDMA) is utilized in the higher rate Wireless Communication Systems (WCSs). In the correspondence framework, a fem to cell is a little cell in building Base Station (BS), which devours less power, short range, and works in a minimal effort. The fem to cell has little separation among sender and recipient that give higher flag quality. In spite of the favorable position in fem to cell systems, there win critical difficulties in Interference Management. Specifically, impedance between the macro cell and fem to cell turns into the fundamental issue in OFDMA-Long Term Evaluation (OFDMA-LTE) framework. In this paper, the Neural Network and Hybrid Bee Colony and Cuckoo Search based Resource Allocation (NN-HBCCS-RA) in OFDMA-LTE framework is presented. The ideal power esteems are refreshed to dispense every one of the clients in the fem to cell and large scale cell. The NN-HBCCS strategy accomplished low Signal to Interference Noise Ratio (SINR), otherworldly proficiency and high throughput contrasted with customary techniques.

Considering that in each region there is at least one brick factory equipped with modern technological equipment, and the reserves of mineral raw materials (sand, clay) for making bricks are practically inexhaustible, the development of an effective structural and technological solution for insulated brickwork is an urgent task. As practice shows, today the majority of brick buildings being erected are low–rise (3-5 floors) – these are secondary schools, kindergartens, clinics, buildings for household purposes (laundries, dry cleaners, etc.), as well as administrative buildings. The floor layout of the premises of these buildings is, as a rule, cabinet (the number of window openings is significant). In this regard, it is proposed to use factory-made insulated brick panels (piers) to reduce the labor intensity of constructing the facades of such buildings. A distinctive feature of the proposed solution for insulated brickwork from those commonly used is that, to increase operational efficiency, it is made of two separate structural elements: load-bearing and heat-insulating and decorative. The paper describes in detail the organization and technology of work on the production of the main structural elements of brick insulated facade panels (piers) in factory conditions. The proposed design solution for the facade of brick buildings with a cabinet layout allows the manual technological process of constructing such buildings to be converted into a mechanized one – installation of factory-made insulated brick panels (piers), which will significantly reduce the labor intensity of constructing insulated brick walls. The division of buildings under construction into tiers, the height of which is linked to the range of technological operations and the building materials used, makes it possible to exclude from the work the use of lifting equipment (scaffolding), as well as the delivery of pallets with bricks and mortar boxes to the bricklayer's workplace.

Mathematics is an important lesson that has a role in human life. This lesson continues from the elementary school level to university, formal education cannot be separated from teaching mathematics. One of the materials in mathematics in elementary school is about geometric shapes which are analyzed to provide phenomena regarding the problems that students will face in their lives. Introducing problems as stories to provide insight to students. have options to solve a problem. This research was carried out in order to analyze what challenges or difficulties were experienced by fifth grade elementary school students when trying to solve story problems based on geometrical material. This requires knowledge of the factors that contribute to student difficulties, and solutions to the problem must be sought. This study uses a descriptive qualitative approach. This exam was guided by 4 out of 5 students at SD Tangerang. This study collected data using a purposive testing method, namely by selecting subjects who had received material about building spaces. Seeing the consequences of the text test above, it tends to be suspected that the challenges experienced by grade 5 elementary school students in solving story problems about building space material are difficulties in describing the state of geometric nets, understanding, and solving problem-based questions, calculating integers and division.

This study analyzed the factors for selecting the type of corporate divestiture for companies listed on the KOSDAQ market in Korea. The factors that led to the selection of the types of corporate spin-offs, physical divisions, were based on the hypotheses of financial motivation and corporate focusing motivation. After selecting variables related to these two, univariate difference test and binomial logistic regression analysis were performed on the 145 companies that promoted corporate divestitures between 2011 and 2020. First, according to the univariate difference test, the debt ratio(DebtR), operating cash to asset ratio (OCFA), and operating cash flow to sales (OCFS), which are variables for verifying financial motivation, all show significant results, indicating a physical division. It was confirmed that it could be a motivation to promote. However, there was no difference between the two divestiture types in the Herfindahl index (Herfin) and the operating index (OPERD), which are variables for verifying the focusing motivation. Looking at the financial motivation variables in the logistic regression analysis, the debt ratio (DebtR), the operating cash to assets ratio (OCFA) and the operating cash flow to sales ratio (OCFS) showed significant results. eanwhile, among the focusing motivation variables, the Herfindahl index (Herfin) did not show significant results, and only the number of business division (OPERD) showed significant results. Looking at the univariate difference test and logistic regression analysis together, companies that promoted physical spin-off had smaller asset size but higher debt ratio (DebtR) than companies that promoted spin-offs. In addition, the operating cash to assets ratio (OCFA) and operating cash flow to sales (OCFS) ratio were also lower than those of companies that pursued spin-offs. Therefore, companies that have pursued physical division are likely to division for financial motivation reasons rather than corporate focusing motivation.
