Increasing the user's need in the building facilities, the architects, engineers, and building managers must consider the user's opinion when they plan and construct the buildings. When planning and managing of the buildings, accepting the user's opinion is desirable and indispensible to solve the Problems about the architectural facilities between suppliers and users. To supply the efficient working environments, use the check listing tools and operate the post occupancy evaluation. The real estate and development company is selected for the evaluation. It is renovated in 2000 to fit in its working environment. The process of the evaluation is proceeded both private and group working spaces and facility and management of the buildings with 10 categories. Following the result of Post occupancy evaluation, the users of the building are mostly satisfied with their working environments after the renovation. However, the categories in thermal environment and indoor air and supply for office work need to be improved in advance.

With the development of Information Communication Technology and a way of solving problems such as productivity improvement, advanced working attitude, greenhouse gas reduction, low birth rate, aged problem, etc., the need of smart work is increasing. Getting out of legacy working types that are limited in time and space, the flexible seat system at a smart work center that supports the smart working environment is proposed. However, the seat choice based on employee's emotional judgement may cause the decline of forming cooperative space and mutual communication because of the scattered seat arrangement between employees. This paper proposed a seat recommendation method for the mutual cooperation at a smart work center. The method is based on a work similarity of employees. A prototype system also implemented to show the feasibility.

Recently, as the characteristics and production methods of the construction industry are changing, and women are actively entering the society, the view of women in the construction industry is also gradually changing. Although the government is currently improving the system to expand women's participation, nevertheless, women's participation in the construction industry is very low compared to other industries. The scope of this study was limited to presenting the actual working environment and improvement plans for male and female engineers in the design office. As a result of the survey on the insufficient part of the work environment, the item 'rest space such as lounge, bathroom, and conference room was narrow' was highly surveyed for men, and 'there was no rest space that required gender discrimination' was highly surveyed for women. As for the improvement measures, both men and women were surveyed highly in the category of 'My place for personal work'. In this study, the scope of the study has a limitation in that it only presents the actual situation and improvement measures for the working environment for male and female engineers in the design office.

Objective: This study examined the effects of working chair that was developed for farmers who work in grapevine's cluster thinning. Background: Agricultural work involves some of the nation's highest occupational risk exposures. Fruit cultivation has been recognized as one of the most hazardous crops in which to work. Grapevine cluster thinning task involve activities related to the main risk factors associated with upper limb work-related musculoskeletal disorders. Method: An experiment was designed to test the working chair. Six healthy male($25.8{\pm}4.9years$) were selected as the subjects for this study. Electromyography(EMG) was used to monitor the muscles activity, and Electro-goniometer was used to measure the ranges of motions of the elbow, trunk and knee. Subjective test was also carried out to examine discomfort body parts and their pain intensity. A grapevine's working space was built for the experiment and working chair was installed on it. In order to examine the muscle activity and range of motion, subjects used to the working chair for 30 minutes for each experimental condition. Another test without working chair was also performed for comparison. %MVC was used to quantify the level of muscle activity. Results: Decreases of muscle activity was found in all leg muscles and significant decrease of muscle activity was found in left Gastrocnemius. The range of motion of the trunk and knee also decreased when working chair used. Discomfort in lower back, thigh and shank region were reduced significantly. However, in upper limbs muscle activity tended to increase in working chair compared with conventional task. Conclusion: Improvement for cushion in seat back and pan required to reduce discomfort in buttocks. Application: Overall findings verified that the working chair might help to prevent upper limb and lower back MSDs based on the current study. These results can be practically used for work improvement for the grapevine growers to prevent MSDs.

German working hour law of 1994(Arbeitszeitgesetz) provides maximum working hour as 8 hours a day and 48 hours per week. The law provides that minimum 11 hours rest-time is required between the end of a day's work and the beginning of the next day's work. Namely, the hour that the workers are put under commanding of the user is restricted within 13 hours per day. In the meantime, article 5, 7, 14, and 15 of the law have some letting the exceptional provisions regarding the working hour and rest-time of flight crew, and 2nd administrative order for the aviation transportation business owner, which is established based on such exceptional provisions(2.DV LuftBO), provides the working hour and rest-time of flight crew quite in detail. The administrative order is detailed quite regarding block time, flight working hour, and rest-time. So, it does not need to interpret additionally. Airlines in Korea should observe the both Labor Standard Act applying to general workers and Aviation Act focused on flight crew, so it is difficult that airlines manages working hour and rest-time of the flight crew efficiently. Therefore, it is desirable that our country refers to and considers adopting this legislation method of Germany which regulates working hour and rest-time of flight crew in detail in the 2.DV LuftBO.

The objective of this research is to investigate the relation between the parenting stress, recognized by the working mothers, and associated variables systematically. For the purpose, I analyzed the demographic of the working mothers and surrounding variables at the levels of microsystem, mesosystem, and macrosystems, to relate with respect to the parenting stress problem. The research composes the sample space of working mothers having children less than 6 years old. The data were analyzed by the statistical method based on frequency, percentile, Pearson's correlation, hierachical and multiple regression. The main results of the research can be summarized as follows: According to the independent effects of diverse ecological systematic variables, there are shown that 11 independent variables can describe about 55.6% of the parenting stress of the working mothers. Among these variables, 'satisfaction about the child care' is the most significant factor, which covers about 34.5%. Additionally, the next significances are observed from such variables as 'temperament of children' (8.2%), 'satisfaction of marriage' (5.1%), 'support of spouse' (1.5%), 'level of education' (1.9%) and so on. In conclusion, it is strongly recommended to compensate and restructure the child care systems more systematically, to afford more reliable parenting environment to the dual earner mothers and fathers and children simultaneously.
