The purpose of this study is to develop the web-based system for work performance analysis(WPAS). The need of work performance analysis system has already been suggested in many previous researches on the computerization of the performance measurement in the construction site by using the indicators such as time, cost and quality. However, they had focused on measuring or analyzing the result when the project would be over. The WPAS suggests three indicators - work reliability, work effectiveness and work efficiency - to manage the performance of the construction site. It can help the manager more easily recognize the status of on-going work in the construction site by measuring and analyzing the work reliability rate, the work effectiveness and work efficiency every day. This research includes the procedures for WPAS measurement process, database structure of WPAS which was analyzed by the IDEF0 and the data flow diagram. Finally, this research introduces the result of WAPS's case studies and validation in the Korean construction site.

Along with the logistics development, heavy-loaded warehouses and sales facilities tend to be bigger and designed as a PC structures. PC erection work of heavy-loaded structures is influenced by various factors, including the required construction duration, site and surrounding situations, safety, PC member procurement, equipment rental cost, which ultimately impact the construction cost. It requires creative efforts and a lot of time when preparing an erection plan in consideration of these factors, and the plan prepared has a great influence on safety as well as the construction duration and cost. However, many engineers do not have enough experiences on PC erection work of heavy-loaded, long span structures, making it difficult for them to set erection plans and establish simulations. The study's results will provide a knowledge to obtain a solution for engineers to establish PC erection plans of heavy-loaded, long span structures.

Porous media consist of physically and chemically different materials and have an extremely complicated behavior due to the different material properties of each of its constituents. In addition, the internal structure of porous materials has generally a complex geometry that makes the description of its mechanical behavior quite complex. Thus, classical continuum mechanics cannot explain the behavior of materials with pore spaces, such as concrete, soils and organic materials in waste landfill. For these reasons, porous media theory has been developed in the nineteenth century. Biot had the greatest influence on the development of porous media theory. Biot's work has been referred by many authors in the literature. Development of numerous fundamental equations in porous media theory were made possible due to Biot's work. His contributions made the greatest influence on porous media theory. Therefore, it is highly advantageous to review Biot's publications. This work presents a review of Biot's work. It shows how porous media theory has been developing so far and provides a chance to discuss the contribution of his work to the modern porous media theory.

Most internet companies in China are learning from Xiaomi Corporation's management model and to improving their organizational structures and human resource management practices. This study analyzed the development situation of Chinese Internet economy and the Internet thinking of Xiaomi which is a role model of Chinese Internet companies. In addition, we studied Xiaomi's organizational structure, human resource management, employee training, performance management and incentive system. In particular, Xiaomi's human resource management system has a great influence on the company's high performance and efficient service culture. Furthermore, the organization of Xiaomi is horizontally divided into three floors (7 key founders, department heads, and employees), each floor is managed by one founder. Xiaomi is interested in and considers not only the work of new employees, but also personal issues, and is concerned with the work of others in performance management and shares responsibility. Xiaomi adopts a unique and rational human resource management model, guaranteeing a lot of work autonomy for employees, and improving organizational performance.

Diagnosis and Prediction of urban industrial structure is a key subject for establishment of sustainable urban development plan. By this time, studies of industry-related urban spatial structure have been concentrated on measurement of space distribution by industry type mainly using data about urban industries or total worker numbers. Now, status of workers become an important issue so this study analyzed qualitative change of urban industrial structure in the view of space using work status classification system. For that, data for work status in 1994 and 2004 were collected in towns and villages, and space analysis units were coincided based on change data between 1994 and 2004. Then, it analyzed spatial distribution pattern of employment through qualitative standard called work status using GIS. The analysis results by work status type of Busan industrial structure in GIS circumstance were as below. First, traditional labor intensive industries met a limit and service and wholesale/retail sale industries went to be poor livelihood. Therefore, Busan's employment rate should be decreased and worker numbers were statistically increased, however, irregular and non-wage workers were suddenly increased. So, it was determined that the quality of employment in Busan area came down. Second, a traditional downtown area has dwindled; on the other hand, employment has been increased in new town or new industrial complex and in the area developed services rather than the manufacturing industry. It is expected that the result of this study may be meaningful as data to prepare for longterm industrial development plan through qualitative evaluation called work status as well as to make behavior pattern of industrial structure which is basis of urban development.

The intention of this study was: 1) to standardize the Korean version of the Dogmatism Scale, 2) to examine whether environmental structure affects value systems such as attitudes toward work, time perspective and the personality dimension of dogmatism in adolescent vocational and non-vocational trainees, 3) to examine relationships between those value systems and group differences in personality characteristics of vocational and non-vocational trainees, 4) to observe whether there are differences between high-dogmatism and low-dogmatism subjects with regard to attitudes toward work and future time perspective. The subjects for the study included 841 adolescent vocational (226) and nonvocational (615) from vocational training centers, schools and universities in Seoul. The instruments used in this study were 1) a questionnaire for attitudes toward work, 2) the Future Time Perspective (FTP) developed by Christiansen and 3) the Dogmatism Scale. The results of the present study indicated that behavior settings or environmental variables such as organization type affect the formation of attitudes and of dogmatism in adolescents. The results also showed that dogmatism relates to future time perspectives. This differs from Rokeach's theoretical statements. Dogmatism in this study was related to time perspective, the relationships were optimistic in emotional areas, long-term in direction and concrete in structure. The inconsistency between the results of the present study and Rokeach's suggests further study. A "Psycho-Environmental Model" for the formation of value systems based on the results of this and earlier research of the author were discussed.

In current complex nature of management with task-structures, a method to reach the enterprise's informationalization success is not common. To satisfy these various requirement, improving the usability of information technology (IT) is a key factor which defining the level of organizational requirement first. Imposing an IT-solution which has excess service of the organization's previous task-environment, procedure and scope is not effective to SME-level unit, which unit could not have a formal organization structure and task structure. SME level informationalization will be success if each function realizes easier on the task-employee's viewpoint. Achieving this objective, a solution provider or department must reflect their work characteristics of nature which has least level of work performing resistance. It is most useful system for SME level unit, if a provider develops single programs which based on task activities, and each program can configure network-linking.
