With the diversified and enlarged softwares, the issue of software maintenance became more complex and difficult consequently, the cost of software maintenance took up the highest portion in the software life cycle. At the same time, in order to develop or use software for general computers the development environment will be changed to incorporate user-friendly 4GL (Fourth generation Language). Therefore, it is required to take a closer look at the languages such as COBOL, C, FORTRAN, PASCAL which have source code comprised of 4GL and investigate the method of analysis and reuse for program understanding since a lot of research has been done with these languages in program maintenance. The purpose of this paper is to propose reverse engineering tool in 4GL and find an effective way of understanding and maintaining the program by transforming source code comprised of 4GL to meta language and designing and implementing Document Generator, Report Generator, Module Generator, Code Translator for program understanding.

This study is to suggest the improving methods for rural community centers by analysis of 30 community centers in Samnangjin-eup, Miryang city, Gyeongnam. To fulfill this purpose, the facilities, usable condition and management system were examined. The user needs and level of satisfaction were also investigated through the interviews with 858 citizens. The average size of the centers is $96m^2$, and 73% of them are one-story buildings. Women use the community center more frequently than men in ratio of 6:4. 43.4% of interviewees visit the center 1 or 2 times a month, but on the other hand 27.4% of them use the center almost every day. Recess is surely the main purpose, and health care and community meeting are next two reasons. 67.8% and 72.4% of them are not satisfied with the inside and outside of the community center respectively. The interview results demonstrate that the most important issue is the lack of facilities. To improve the community centers in Samnangjin-eup, first of all, various kinds of indoor and outdoor facilities must be equipped. Secondly, considering the center is the core of rural community life, the qualitative improvement in accommodation is also needed as well as facility diversification. The efficiency of space utilization is another issue. A small piece of land or abandoned space must be utilized. Moreover, it is very critical that the users are mostly seniors and elders, so improvements of facilities will be executed in terms of safety and convenience. Finally, administrative and financial support should be made for the people, so as to maintain the the rural community center on their own.

Autonomous knowledge service, a fully-automated and pervasive service for knowledge acquisition and support based on the power of recent ITs is gaining tremendous interest more and more, as not only the level of users' intelligence increases but also the maturity of IT infrastructure improves. Conventional approaches of knowledge service, however, could not satisfy users because they usually provided undesired knowledge which had been acquired without considering users' want. In other words, knowledge acquisition and distribution were separately performed. This research, therefore, suggests an amended autonomous knowledge service framework by fully-automating the whole phases of knowledge life cycle, from knowledge acquisition to distribution. ASKs, the prototype system of this research, is also implemented by defining and specifying component technologies which constituently compose suggested framework. More user-friendly and applicable way of knowledge service will be derived and facilitated through this research.

For successful projects, Project Management Information System(PMIS) using the formal systematic processes is necessary. Because the existing PMIS focuses on low-level project management, the life-cycle administration of the projects is required. In this dissertation, I describe not only the processes for managing a project with the top-down approach(a hierarchical goal setting of the project outcome), but also PMIS which can control whole processes of R&D projects. The PMIS described in this dissertation can reduce the workload of project management by providing user-adaptive environments and linking with related systems, so can be helpful to enhance the efficiency of the project management. And, it is expected that these processes can be the standard project management processes which are adaptive to various types of projects.

Objective: This study carried out base research to build an agricultural safety monitoring system through ICT convergence to reduce safety accidents and enhance welfare in life in the agricultural field. Background: The functions and values of rural villages as the space of living are recognized anew, but occupational accident rate due to farm work accidents is on the rise each year. Therefore, the seriousness of such a problem emerges. The convergence technology combining ICT is recently applied to industries overall, and therefore better services are offered. However, studies on ICT convergence has not yet been applied to the agricultural safety field. Method: This study identified ICT convergence service technology trends and representative serious accident types mainly occurring in agricultural activities. This study defined the major factors of farm work accidents and ICT to solve those accident factors including the sensor technology, wired/wireless communication technology and location information service, and applied them to prototype PCB for the development of an agricultural safety monitoring system. Results: This study proposed an emergency monitoring system for farmers and a harmful environment monitoring system. The ICT technology to prevent farm work accidents can be summarized as sensing technology, ICT and network technology and user interface technology. This study also designed PCB module configuration and situation judgment algorithm as basic research for proposed monitoring system development. Conclusion: The ICT-based agricultural safety monitoring research proposed in this study is expected to become the basis to build a future real time monitoring system, and also is expected to contribute to social safety and welfare service improvement for farmers.

Objective: The purpose of this study is to extract GOMS manual operator, except for an experiment with participants. Background: The GOMS model has advantage of rapid modeling which is suitable for the environment of technology development which has a short life cycle products with a fast pace. The GOMS model was originally designed for desktop environment so that it is not adequate for implementing into the latest HCI environment such as small touch screen device. Therefore, this research proposed GOMS manual operator extraction methodology which is excluded experimental method. And flick Gesture was selected to explain application of proposed methodology to extract new operator. Method: Divide into start to final step of hand gesture needed to extract as an operator through gesture task analysis. Then apply the original GOMS operator to each similar step of gesture and modify the operator for implementation stage based on existing Fitts' law research. Steps that are required to move are modified based on the Fitts' law developed in touch screen device. Finally, new operator can be derived from using these stages and a validation experiment, performed to verify the validity of new operator and methodology by comparing human performance. Results: The average movement times of the participants' performance and the operator which is extracted in case study are not different significantly. Also the average of movement times of each type of view study is not different significantly. Conclusion: In conclusion, the result of the proposed methodology for extracting new operator is similar to the result of the experiment with their participants. Furthermore the GOMS model included the operator by the proposed methodology in this research could be applied successfully to predict the user's performance.

In this study, POE(Post Occupancy Evaluation) evaluation indexes were selected into six categories through the consideration of theories and prior research. Therefore, qualitative supply can be achieved through POE according to the aspect of residential environment after the quantitative supply of mixed-use apartment complex by the population concentration in Seoul due to industrialization and urbanization. As the evaluation elements, detailed survey contents were selected for livability, convenience, comfort, safety, economy, and sociality. Based on the survey contents, six elements were evaluated and analyzed using Data coding and Likert scale after surveying 12 complexes (Urban areas and non-urban areas) in Seoul. As a result of the study, six categories selected as the POE showed that importance of quality of life and safety was developed in high recognition according to high satisfaction with convenience and safety. Sociality showed the lowest satisfaction in the following order : livability, comfort, economy and sociality. Residents' sense of community, interaction with neighborhood, etc., showed low satisfaction, and it seems that it is necessary to improve and supplement the system for the development of mixed-use apartment complex in the future. The detailed characteristics of livability showed high satisfaction of the living room, the front door and the main room which are main uses of housing, and low satisfaction in storage size. The analysis of convenience is that convenient public transportation was the highest, and educational environment and additional facilities were the lowest, showing the advantages and disadvantages of location characteristics. As a result of the analysis of comfort, satisfaction with the landscape area was low and it seems that green space is needed for the development of mixed-use apartment complex in the future. Lastly, regarding the safety, the satisfaction of the access control, the location of security office, etc. were high, however separation of circulation was low. Therefore, it is necessary to clearly separate the circulation between the residence and other facilities in the mixed-use apartment complex.
