Office workers at the architectural design office are under job stress for various reasons such as excessive working hours, friction with the site, and unpredictability of work. This can increase not only the negative image of office workers in the construction industry, but also the avoidance of young manpower in the future. This study investigated the specific purpose of each activity as a problem of job stress relief activities in the architectural design office, and the specific purpose and goal setting of each activity as a way to improve job stress relief activities.

This Paper analyzed simultaneous activities of the time use survey by Korea National Statistical Office to use data mining's association rule. The survey of National Statistical Office in 1999 considered general analysis for main activities like that personal care(eating), employment and study, leisure, travel by purpose. But if we use the association rule, we can found the ratio of simultaneous activities at the same time. And also we can found the probability that another activities practise if we act one particular activity. Using this association rule of data mining we can do more developed and analytical sociological study.

The purpose of this study is to analyze elementary school students' class contents and activities between the invention class for the gifted under the local education office by the 'Gifted Education Promotion Act' and that under the invention classroom by the 'Invention Promotion Act'. For this study, the survey was conducted to 1,788 elementary school students who attended the invention class for the gifted both under the local education office and under the invention classroom. The analysis of the survey showed that the students of the invention class for the gifted under the local education office had higher motivation and participation rate in class, higher interest in invention, and stronger significantly in a future oriented will than those under the invention classroom. The parents of the invention class for the gifted under the local education office showed more enthusiastic attitude to support their students, and had significantly stronger recognition that the participation of the students in the invention education for the gifted helped enter an advanced school than those under the invention classroom. However, the class contents of the invention class for the gifted under the local education office such as 'understanding the influence of the invention history and products on society', 'scientific inquiry skills for problem solving', 'technological and engineering abilities for creating an invention', 'developing knowledge and abilities about business and management by using a new invention' were not different from those under the invention classroom. In addition, discussion and presentation were not active in the class activities of the invention class for the gifted under the local education office. Therefore, the researchers should compensate and develop a program which can apply strategically differentiated class contents and class activities to the students who participate in the invention class for the gifted under the local education office by the 'Gifted Education Promotion Act'.

Background : Evaluation of patient's satisfaction is one of the most important aspects of quality improvement. If the patient highly satisfies with the medical service provided in the hospital, he/she will be likely to visit the same hospital again. Patient's satisfaction of a particular hospital is directly correlated with hospital profits as well as reputation in the community. For this reason, various kinds of survey measuring satisfaction level have been performed and many kind of QI activities for enhancing the profits as well as reputation in the community. For this reason, various kinds of survey measuring satisfaction level have been performed and many kind of QI activities for enhancing the patient's satisfaction. This study is to find the effect of hospital QI activities on the patent's satisfaction level. Methods: After questionnares were developed, survey of measuring satisfaction level was performed in August, 1998. On the basis of survey results, QI activities were carried out to attain the target point of 4.0 and subsequent survey was done in November, 1998. Results: With three main principles of "problem solving approach with kindness". "helping patient to participate in medical procedure with sufficient information", and "putting employees into practice of attitude with human respect", the average level of satisfaction was enhanced from 3.45 to 3.55 level. Also kindness level of employees was increased from 3.71 to 3.82. Level of dissatisfaction about insufficient explanation and unkind attitude was dropped from 69% to 48% and from 82% to 46% respectively. Conclusion: With the result of this study overall satisfaction level was enhanced. In order to keep these advantages a operation of Quality Improvement Task Force Team in each subject will be required.

The purpose of this paper is to investigate office location dynamic in Seoul and to analyze comparatively the office activities of emerging office centers. Since mid 1980s, the expansion of office employment and spatial differentiation of the office-type jobs have changed the employment and spatial structure of Seoul. The major employment centers are CBD, Kangnam district and Youido. Among these, CBD and Kangnam have developed as the two leading centers of Seoul. Youido, the typical office-oriented center, shares CBD functions especially specializing security business. Selective decentralization of offices made qualitative differences among the centers. In spite of vigorous office decentralization, CBD has kept the principal offices of finance and insurance, travel agencies, advertising agencies, management consulting firms, major public institutions and headquarters of upper 100 companies in Korea. But the offices of producer services such as law, architects, engineering and computer consulting and real estates and headquarters of upper 5000 companies in Korea have been decentralized dominantly to Kangnam.

This study based on DeLone and McLean's IS success model aims to identify mobile office service factors affecting user satisfaction. The result of analysis showed that user satisfaction was positively related to job performance, and mobility and information quality affects user satisfaction. In addition to that, we carried out separated hypotheses test to investigate mobile office service factors depending on usage(frequently used functions) and job characteristics classified generally as either primary or support activities. As a result of this research, somewhat different results were derived. The main results of this study are that mobility is the most important factor affecting user satisfaction, and mobile office services should be more strictly guaranteed in quality especially if it supports primary activities of customer companies such as sales.
