  • Beginning January 2005, the BTL (Build-Transfer-Lease) project was initiated by government to provide high level of public services for the upgraded quality of life. The most important process of the BTL project is operation, because the company have to operate the building about $20{\sim}30$ years after completion. But a lot of problems have been founded so far. For example, no counterplan for the risk in operation, no total control system and the vagueness in project guideline and so on. These problems will cause serious demage to the BTL project. Hence, this paper analyzes the above issues and conducts the interviews with the professionals from the diverse sectors in order to propose the improvement and deliver the successful operation in BTL project.

  • Nature-friendly river project has became common practice in Japan. In order to make it available for the conservation and rehabilitation of desirable water environment, water criteria for water environmental assessment must be established. Especially, the criteria estimating the effects on ecosystem in and around river should be constructed. In this paper, classification method for water quality has been developed using biological indices and applied to observed data in Honmyo River, Nagasaki, Japan. Modified PI method (BI') has been suggested and those of three most abundant species resulted effective estimate for an overall water quality with comparatively simple procedure. Extensive database management code was prepared for the comprehensive ecological monitoring of river basin, which includes various biota. That system enables easy access of all the ecological data for a dissemination of a sound and sustainable water environment. The result of this study could improve knowledge base, serve making consensus for citizens, and help river management plans. In Japan, citizen's realization and action are the most critical factor for nature-friendly river restoration project.

  • This study was conducted to suggest effective storage methods for the use spent mushroom (Flammulina velutipes) substrates (SMS) as animal feed. SMS was storage by deep stacking, composting and vinyl mulching after treated with 1% microbes and 0.5% formic acid. During the storage periods, all of the treatment was covered with hyphae of mushroom. The external change of SMS was shown that the storage of SMS can be improved by anaerobic condition and 1% microbial treatment. The comparatively high temperature, pH and total bacterial number was shown in the SMS treated without microbes and formic acid by composting.

  • $900^{\circ}C$이상 초고온 He-gas 분위기 또는 용융불화염 (molten salts, FLINAK) 환경에서 사용될 VHTR(Very High Temperature Reactor)의 IHX(Intermediate heat exchanger)용 열수송 구조재료로 가장 가능성이 높은 합금인 Inconel 617 및 Hastelloy X 상에 습식화학적, 물리적기상합성법(Vacuum arc-plasma과 RF magnetron sputtering) 및 pack cementation에 의한 표면개질 및 마이크로 초내열(refractory ceramics) 코팅층(TiN, TiCN, TiAlN, $Al_2O_3$, $TiO_2$)을 형성시켰다. 고온 장기사용 시 문제가 될 수 있는 고온에서의 조직변화, 미세구조와 상(phase)형성, 고온 부식 및 그에 따른 마모(wear resistance) 손상 등 이들 소재의 내열, 내식 및 내마모 물성을 개선하는 연구를 수행하였다. TiAlN 박막의 경우 공기분위기에서 N이 분해되나 치밀한 산화물($TiO_2/Al_2O_3$ layer)을 형성하여 내식성 있는 보호피막을 형성함으로 기판과의 열팽창 계수로 인한 박리가 발생하지 않아 보호피막으로 적합하였다. Pack cementation법에 의한 aluminiding(Al-Ni합금)도 He 및 공기분위기에서 고온물성의 저하를 가져오는 $Cr_2O_3$의 생성을 충분히 억제하고 있었으며 He 및 air 분위기에서 사용이 가능한 박막으로 여겨진다. 내열 및 내식성에 대한 실험을 종합한 결과, 공기분위기에서 사용할 수 없는 박막은 He-gas 및 FLINAK(LiF-NaF-KF) 용융염 분위기에서도 사용할 수 없었으며, He-gas, FLINAK 및 air 분위기에서 모두 사용이 가능한 박막으로는 Inconel 617에서는 $(TiO_2-)Al_2O_3$, TiAlN 및 Al-Ni이었고 Hastelloy에서는 Al-Ni 및 $Al_2O_3$가 가장 적당하였다.

  • After choosing twenty sluice culverts located at national rivers by detailed appearance evaluation, hydraulic response test and acoustic televiewer in addition to surface geophysical explorations were carried out to investigate the cavities which exist at the boundary of sluice culvert and ground. Tapping, GPR, 3-D resistivity surveys and acoustic televiewer imagery obtained successful results in limited conditions according to characteristics of the sites. On the other hand, hydraulic response test successfully detected cavity existing at the lower part of sluice culvert and its continuity. However, hydraulic response test can not supply the quantitative informations on the scale and the shape of cavity. Thus it is very important for accurate investigation to make comprehensive interpretation after supplying various surveys proper to site characteristics.

  • To enhance gamsulgi quality, the optimal conditions for persimmon peel powder (PPP) addition were evaluated with PPP content(10, 50), sugar content(5, 25) and water content(10, 50%) by reponse surface methodology (RSM). The statistical significanes of sugar element in gamsulgi preperation did not show. Optimal conditions for the content of PPP and water, predicted for each corresponding sensory parameter of gamsulgi, were 10∼40% and 18∼50% for consistency, 10∼32% and 11∼50% for after swallowing, 24∼50% and 14∼39% for color, 10∼40% and 31∼50% for chewiness, 14∼38% and 22∼47% for moistness, 10∼38% and 22∼50% for texture, and 10∼43% and 18∼50% for overall quality. The overall optimal conditions, which satisfied with all sensory properties of gamsulgi, were 25% for PPP content and 35% for water content.

  • It has been recently emphasized that comprehensive understanding of students' cognitive activities in the process of writing as well as final product is needed in order to develop an effective strategy for science writing. In this study, we investigated the characteristics of writing process in the situation that students wrote a composition in solving the application problem on a science topic. Seven eighth graders selected in the consideration of their science achievement and communication skills were asked to write a composition using think-aloud method. They were also interviewed after their writing work. The analyses of the results indicated that students' writing processes consisted of six distinctive components: generating, organizing, setting, translating, evaluating, and revising. It was also found that the patterns of process components for each student were different in terms of the frequency and the sequence. The patterns of process components were categorized into four types: systematic, tacit planning, trial and error, and random strategies. Educational implications were also discussed.

  • The manager of manufacturing industry just not to have known to do related to the law of Product Liability that was put into operation in July 2002. The law of PL is a public law about defective product, which was established in order to compensate consumer's damages of property and body caused by product, to make sound society by the safety products and to take international competitiveness. The economic effects by the law of Product Liability are the increase of consumers relief production cost by the lawsuits. Product liability as a process has developed significantly in the United Kingdom and the United States of America. The rapid introduction of product liability has recently been a prevalent phenomenon, as global changes arising from rapid development in science and the economy have resulted in a highly interconnected world economy. This thesis was established, based on current literature and business consulting cases in the position of companies, and is one of the operating subjects in a system for legal responsibility in manufactured products. However, there are limitations in the fact that research theories are only able to present a theoretical model and directions. In this context, managers and personnel of multiple companies cannot adequately respond to the recently enforced Product Liability Act. The major findings are summarized as Product Liability Management Activity are positively Correlation of Enterprise Value.

  • The purpose of this study is to identify theoretical basis of information literacy program in the Korea. Nine Information Literacy Program were compared with ACRL Information Standards. The result of this study is as follows: (1) The identification of information needed was included in the programs that emphasized a thesis or topic statement and formulated question, critical thinking, information technology. (2) Most programs contained mainly potential sources for information. (3) Each programs had element of Information access strategy and skills that explained to OPAC, Indexes and Abstracts, On-line retrievals. (4) Implements the search strategy using various formats was essential elements in the programs. (5) Evaluation and synthesis was included in the programs, partially evaluation for information process and satisfaction was included. (6) The writing skills for termpaper. quotations and oral presentations are important elements of information use in the programs, however. those programs didn't contain enough the ethical and legal uses of information with respect to the standard.
