As the VDT work constrains work postures because of its work characteristics. VDT worksta- tions should be properly designed so as to be fitted to various types of physical conditions of op- erators. Therefore, in this study, the preferred settings of VDT wrokstation dimensions of operators. Therefore, in this study, the preferred settings of VDT workstation dimensions and work postures were studied in order to determine the appropriate dimensions and the work postures for VDT operators which will alleviate the musculoskeletal troubles or visual fatigue. The scpoe of the study is as follows. 1. Measurement and analysis of the preferred settings of the height of workstation, keyboard, seat, and screen among the experienced VDT operators. 2. Anaysis of the relationship between the preferred settings of workstation height and the seat height control among the experienced VDT operators. 3. Analysis of the work postures of the experienced VDT operators.

In this paper we applied dynamic programming to determining work schedule type. In dynamic programming formulation, each day during a planning horizon represents a stage for which a decision is made. The alternatives are given by work schedule types that combine regular time, overtime, additional shift, and so on. In this case, their associated return function is labor cost. The state is defined as the amount of work time allocated to stage 1, stage 2,…, and current stage. A case study for a real manufacturing company was performed to apply dynamic programming to scheduling daily work hours during a week. The case study showed that total cost of our solution derived from dynamic programming decreased by about 6％ as compared with the solution obtained from the previous method.

The purpose of this study is to review the concept of home-based work, introduce the activities of American home economists on home-based work and propose the tasks of family resource management for home-based work. Home-based works is defined as the work which generates income at home and classified 3 types: home-based business, employed home-based work and homework. The activities of American scholars are reviewed focusing on the Coorperative Regional Research Project, NE-167, entitled "At-Home Income Generation: Impact on Management, Productivity and Stability in Rural/Urban Families"and the participants of the project. Finally the tasks of family resource management are pursued in terms of research, education and service.d service.

This study examines how practical work in science was introduced in British schools and became an important part of school science activities during the second half of the 19th century. Firstly, the establishment of a national education system in Britain is reviewed. Secondly, a general development of school science teaching is summarized with a special attention to students' enrollment in science subjects. Thirdly, the practical work in elementary schools are discussed in relation to the introduction of Object Lessons in curriculum. Then, the situations of practical work in science in secondary schools, particularly in Organized Science Schools and some famous public schools, are illustrated. Finally, the overall development until present days is critically discussed in relation to the types and aims of practical work in science.

Death disaster among the disasters in construction field is mainly occurred by crash, and the work plate is the main objects causing crash. This study was performed by interview with workers in construction field to evaluate the consciousness on safety and to analyze the type of use and the state. Finally the problems while using work plate were appeared with its requirements for the improved use. Based on the results from this study, amendments were proposed for some parts of regulation related, and further four types of development on the safe work plate were presented. It is expected that the safer construction environment could be composed by using the results.

Purpose Today, through digital services, many people enjoy a conveient and comfortable life. Nevertheless, it is easy to find people in our daily lives who are buried in work without any payment that we did not do before digital services. Such un-payed works under digital environment are called digital shadow works. The purpose of this study is to classification and dynamics of digital shadow works and to suggest research direction. Design/methodology/approach Based on two dimension, voluntary participation ('should' type and 'want' type) and work orientation (management-operation), digital shadow works were classified into four categories - chore, makeup, routine, and quest. Findings In digital shadow work there are four types of dynamics - routine and quest, makeup and chore, makeup and quest, and quest and actions in offline. According to the classification and analysis of dynamics, three research directions in digital shadow work are suggested and discussed- digital shadow works operation mechanism considering dynamics, expansion of existing user theories based on survey method by digital shadow works and social influences by digital shadow works.

Maintenance is carried out over a long period of time, and various documents are utilized in the maintenance work. In maintenance work which is progressed simultaneously in a short period of time, it is important to provide relevant information to the parties in a timely manner. As the types of work increase, manager needs more time and effort to select and utilize the documents. It is necessary to have an information system that supports the person in charge by grasping work procedures for each construction and providing the necessary documents and information for that step. This paper proposes an process based nexus model that can provide necessary documents to the parties to the work steps by linking the maintenance work process and BIM. Through the nexus model presented, manager can efficiently acquire the necessary documents and utilize them for the construction works currently being carried out.

This study classified the current work-life balance of full-time female paid workers and tested the typology by using the 2009 Korean Time Survey. The categorization demographic and psychological characteristics of women belonging to each type were comparatively analyzed. It was found that full-time female paid workers used an average of 435.7 minutes for work, 146.4 minutes for family, 104.5 minutes for leisure, and 17.7 minutes for growth. On the basis of times used in each area of work and life, individuals were classified into family-oriented type, work-leisure parallel type, work-oriented type, work-growth parallel type, and work-family parallel type. Psychological characteristics were examined by type. The work-oriented type women experienced feelings of lack of time and fatigue the most compared with women of other types. From examining the influence that the amount of time used in each area of work and life had on psychological characteristics, it was shown that the activity time relevant to leisure influenced psychological characteristics the most. Lastly, based on the limitations of this study, future assignments are discussed.

Objectives: This study was conducted to find out the prevalence and risk factors of anemia according to shift work. Methods: Data from the Korean National Health and Nutrition Survey (2016-2020) were used. 9,787 workers were divided into shift workers and non-shift workers. The work type between 6AM-6PM was defined as day work, and other work types were defined as shift work. A chi-square test was used to indicate the distribution of risk factors expected to affect shift work in both frequency and percentage. Multiple logistic regression analysis was performed to find out the relationship between anemia prevalence and shift work. Results: As a result of analysis, multiple logistic regression analysis of anemia prevalence and shift work, the OR (95% CI) of male workers on shift work was 2.186 (1.139 to 4.194) and there was a statistically significant difference. Conclusions: In conclusion, anemia in male shift workers should be considered a possibility of health problems. In the future, research based on various data collection should be conducted for research to reveal various causes or diseases of anemia in the future.
