To enhance success probability of a system development project, its overall risk level should be minimized through systematically managing schedules, costs, and technical performances. However, Attempts to manage technical performance compared to numerous efforts to control costs and schedules in such projects are deficient. Particularly, a space launch vehicle, a large complex system, development project is much less likely to meet its technical performance objectives due to its technological difficulty, along with schedule delay and cost overrun. The technical performance management (TPM) is a method for tracking and managing technical progress in order to achieve technical performance targets within schedule and budget. In this paper, we investigate applications of the TPM in several space launch vehicle development projects. Then we propose and validate the TPM process to achieve a successful mission in such projects.

This study aims to examine the operating status of the Farmer's Health Center Project and the validity of its business using the benefit-cost analysis. As the pilot project of the Rural Development Adminstration from 1996, a total of 884 Farmer's Health Centers were established until 2004. Internal information of the RDA management unit was used for the analysis. A questionnaire with an interview was also performed with 70 over 468 Centers that had been established from 2001 to 2004. Results were as follows. 1) The Center was mainly used by elderly over 60 years, which took 71.4%. Winter was the most popular season for visiting. 2) Approximately 71% of the manager of the Center pointed out the deficiency of fuel cost as the most difficulty in operating the Center. 3) Users were moderately satisfied with facility and the effect of its use, which took 3.5 point over 5 scale. 4) For the cost-benefit analysis on the Centers, both 5% of social discount rate and 15 years of use term were assumed. Subsequently, the Net Present Value was 3,134 million won, which certified the validity of the business.

This thesis analyzed the uniqueness of a toilet plane structure, centering on a case of Beautiful Public Toilet Construction Project under a project by Chungcheongnam-do and drew a conclusion as followings. Most of public toilets, constructed under a project by Chungcheongnam-do, were located in remains, tourist resorts, parks, and the outskirts of traditional markets. They were constructed at the selected location within an easy access of most user and plane structure was also designed so that the persons, in charge of management and maintenance, and the users could use them without difficulty. But some public toilets didn't establish the handicaps' toilet or made them difficult to sue due to location or size. The plane structure style was various such as a rectangular, stream line, or circle in accordance with location or building size. A circle-styled toilet offered a good view but didn't offer a good access or an effective space for users. In addition, when a handicapped person enters a toilet, he or she has to enter or go out of it through a sliding dor. So a constructor has to make progress of a work in accordance with this point.

Recently, the construction industry is increasingly in need of securing safety rights due to repeated serious accident. Accordingly, the government enacted the "Serious accident Punishment Act" to strengthen punishment for serious accident and expand the scope of punishment. However, safety managers in the construction industry are still vulnerable to safety accidents due to the heavy workload. The purpose of this study is to increase the efficiency of performance tasks and reduce serious accidents in the construction industry through analysis of performance tasks by stages of construction projects. The tasks derived through domestic research and domestic and foreign system analysis were classified step by step to analyze the correlation between difficulty and preventive effect, and inefficient tasks were discovered and improved. This can be used as basic data for identifying safety management tasks and preparing effective safety prevention measures, and it is expected to be a preventive measure against industrial accidents in the construction industry by using it for efficient work reorganization by safety managers.

This paper discusses issues faced by individual building industry clients. These form the majority of clients but, because they do not possess high purchasing power, they attract less attention in the industry. Given that key decisions on project definition and procurement strategy are made at the pre-project stage, the industry would benefit from knowing relevant aspects of its clients' attitudes and behaviors, so that it can support them. There is a lack of research on this subject, and so we first describe a theoretical framework and research methodology that were developed for this specific group of clients. Theory adopted from consumer behavioral research was introduced to develop a general behavioral model of individual clients. In this model, individual clients are assumed to seek and then process information after acknowledging normative activities. To validate our model, a field survey was conducted using randomly selected individual clients. Their opinions on the importance and difficulty of 12 normative activities were analysed to establish a general attitude. Information seeking behaviour was investigated by measuring the frequency and type of source that they contacted to conduct the normative activities. The attitudes and information seeking behaviour presented in this research will contribute to the development of project tools for supporting these clients.

The purpose of the research was to find out the difference in students' academic achievement in Technology Education between students with a lecture, those who perform a content-related project after a lecture, and those who carry out a content-related project without a lecture. The results of this study are as follows. First, taking advantage of both a lecture and project-based lesson led to better achievement than using only a project in Technology Education subject of an academic high school in academic achievement in 'knowledge' area. I infer that it is because they reviewed what they had learned in a lecture and the preparation and practice of the project caused them to memorize it. Second, there was not a meaningful difference in academic achievement in 'understanding' area among the group with a lecture, the one with both a lecture and a project, and the one with only a project. However, considering the comparison of averages and the p-value of F-test, I can deduce that the test outcome influences students with a lecture and a project positively in terms of academic achievement. Third, there was not a meaningful difference in the academic achievement in 'adaptation' area among the group with a lecture, the one with a lecture and a project, and the one with a project. I can conclude that those results are because the difficulty level of evaluation was high and they produced a model just by copying textbook contents.

Usually, processing whole project or a part of frame work delays due to acceleration, changing orders, management, characters of project. overtime, worker crowding, early occupation in the field of construction. Through a whole project, these factors cause decreasing construction labor-productivity which is the most dependent in business of construction. These kind of decreasing of construction labor-productivity cause many negative effects, just as extension of time, increasing cost in project of construction. Regardless of characters of construction or decreasing labor-productivity, extension of time is a incident which needs acceleration, also it cause a high possibility of claim and dispute. The productivity has just a broad meaning in business of construction. That's why it's difficult to apply in the field of construction. Especially, factors increasing or decreasing labor-productivity is defined by analysis of working as qualitative and outlined evaluation. However, study of the each factor decreasing construction labor-productivity analysis has not researched, because of difficulty of systematic measurement and management. The existed studies about management of productivity are just focused on estimation of productivity, not on evaluation of productivity. It was true that I couldn't examine clearly about the analysis of how much important per each the factor which have influence on labor-productivity because of the characteristic as qualitative that the labor productivity have On this study, i tried to get the factors decreasing of labor- productivity with gathering opinions of panels of expert's studies about the factors decreasing of labor-productivity on project of construction through Delphi method and i evaluated the result factors as quantitatively and subjectively about importance of factors decreasing construction labor-productivity Analysis, using AHP Method by Saaty. Also, using Delphi and AHP method, 1 suggest substantiated method qualitative factors are measured by quantitative criteria.
