The production of abalone seed has grown and been specialized since the 2000s with the growth of the abalone farming industry. Despite the increase in the production of abalone seeds, the sales volume of abalone seeds remained flat and competition among producers increased. This paper will analyze the management efficiency of abalone seed production fishery to diagnose the management status and improve the abalone seed production efficiency. In addition, this study is the result of the basic research on the abalone seed industry and it is meaningful to prepare a platform for further research since the management status survey and the management efficiency survey of abalone seed production fishery have not been conducted until now. The data on the farmed fish prices of abalone seeds were collected from surveys of sample fish as part of the fish seed observation project conducted by the Fisheries Outlook Center (FOC) of Korea Maritime and Fisheries Development Institute (KMI). Management efficiency analysis utilizes DEA (Data Envelopment Analysis) model. The DEA model was analyzed by classifying into CCR (Super-CCR), BCC, and SBM (Super-SBM) models according to the assumptions taking into account the characteristics of the industry. The slack considered in the SBM model was judged as possible decreases in input variables and increase in output variables. The average efficiency from the CCR model was analyzed to be 69%. The BCC model was classified into input and output orientations, and the average efficiency was 79% and 75%, respectively. There were seven production fisheries with an SE value of 1 or more, which remained unchanged in terms of size and could be benchmarked. The average efficiency of the SBM model was 59% for CRS and 66% for VRS. Under the VRS assumptions, the variable increase/decrease efficiency analysis shows that labor costs can be reduced by 37.3%, facility capacity by 18.8%, and operating costs by 8.5%. In order to improve management efficiency, Wando needs to reduce labor and management costs. In Jindo region, sales increase as well as labor cost reduction is urgent. In other regions, reduced facilities and increased sales are recommended.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. Among u-City elements, the u-City Management Center has its own meaning and importance in roles which are crucial to the u-City developments, and its legal establishment is one of the core u-City realization factors. The purpose of this study is to analyse its overall problem issues regarding the function and location of u-City Management Center and then to suggest the basic direction and enforcement strategies to form its legal basis. As a result, in order to enhance the possibility of successful realization of u-City Management Center, the classification and standardization of function type, allocation of detailed functions based on u-City project hierarchy, and practical definition and relationships among basic u-City components such as u-City Service and Infrastructure were suggested. Also, practical execution devices on revenue sources and private sector participation, as well as the legal basis stipulating the mandatory inclusion of u-City Management Center development for u-City projects, were suggested.

Understanding of the social perception of biotechnology would facilitate the public awareness and debate over the social implications of biotechnology, leading to strengthened basis for social consensus. As a part of the ELSI (Ehical, Legal and Social Implications) project in Korea, the authors have launched a series of social surveys on the social perception of biotechnology. This article is based on the analysis of the first survey, conducted in October 2001. The data were collected through telephone survey on 500 adult respondents nationwide selected by a stratified sampling method. The survey addresses the following questions: What is the present state of public awareness and attitude toward a variety of medical and social applications of biotechnology, such as genetic testing, prenatal genetic screening and testing, xenotransplant, genetic screening for employment, central collection and management of genetic information, and GM food? What factors are related with this perception? The analysis shows that a majority of respondents are in favor of the medical applications. Concerning the social applications and GM food, however, the respondents express a high level of negative attitude a with significant portion of 'do not know' responses. The public perception of the biotechnology is not crystallized in coherent manner yet. The public perception is strongly influenced by mass media, which tend to deliver rather positive information on biotechnology. The analysis suggests that the production and dissemination of diverse information should be activated to reach a sound decision on controversial issues surrounding the development of biotechnology both at individual and societal level as well.

The purpose of this study was to explore the implications of the integrated support through the 'health - medical - welfare' network and the specific context of the operation through the experiences of the users who participated in the 301 network project of Seoul northern municipal hospital. To do this, In-depth interviews were carried out with 10 research participants. The data was analyzed by general qualitative research methods. As a result of analysis, users lost their willingness because of living in a vicious cycle of poverty and illness before participating in 301 network services, but through the participation of the service, they were able to receive the integrated support of 'cure-care-life stability'. These experiences ultimately led to the regeneration of the will of their lives. At the basis of this experience were operating strategies and conditions such as the formation of a diverse professional team, the establishment of a linkage system within and outside the hospital, the establishment of a treatment linkage system through the acquisition of treatment subsidies, and the linkage of resources at mediation level. As the attempt to integrate 'health, medical and welfare' with well-coordinated strategies and conditions showed the possibility of complementing the limitation of the health welfare support system in Korea, the extension of the related business was suggested. For this, it suggested the more stable stabilization of the linkage system and the improvement of the institutional aspect.

As the first comprehensive attempt at a national implementation, this study aims at assessing the external costs of major electricity generation technologies in Korea, particularly an evaluation of the impacts on human health resulting from exposures to atmospheric radiological emissions from nuclear power plants, and a monetary quantification of their damages. The methodology used for the assessment of the externalities of the selected fuel cycles has been developed by the International Atomic Energy Agency (IAEA), namely the SimPacts Model Package. The model is internationally recognized as a tool which can be applied to a wide range of fuels, different technologies and locations, for an externalities study. In this study, the relevant emissions are quantified first and then their impacts on human health are evaluated and compared. The study focused on all the nuclear power plants for the last 6 years ($2001{\sim}2006$) in Korea. With respect to nuclear power, the impact analysis only focuses on a power generation, however the front- and back-end nuclear fuel cycles are not included, namely uranium mining, conversion, enrichment, reprocessing, conditioning, etc., because these facilities are not present in Korea. The analysis results show that nuclear power in general, generates low external costs. The highest damage costs from the nuclear power plants among the 4 sites in Korea were estimated to be 3.9 mills/MWh, which is about 1/20th of the result for a similar case study conducted in the U.K., implemented through the ExternE project. This difference is largely due to the number of radionuclides included in the study and the amount of released radioactive emissions based on up-to-date information in Korea. In this study, the sensitivities of the major factors for nuclear power plants were also calculated. The analysis indicates that there was around a ${\pm}3%$ damage costs variation to a ${\pm}15%$ change of the reference population density and a ${\pm}1%$ damage cost variation to a $1{\sim}30$ meters change of the effective release height, respectively. These sensitive calculations show that there is only a minor difference when the reference costs are compared.

This study attempts to extract the necessary criteria as a secondary school home economics teacher through the factor analysis, and to analysis the teacher's and student's perceptions for the requirement criteria of home economics teacher(RCHET) thereof to confirm the necessary criteria as a secondary school home economics teachers. This research was based on the requirement criteria of home economics teacher developed by Korea Institute for Curriculum and Evaluation(KICE) Korean Home Economics Education Association(2008)(KHEEA) collected from secondary, upper secondary school home economics teachers and students in Jeollabuk-do. RCHET encompasses the six areas : (l)'Expert of lesson related to evaluation' (2)'Efficient manager of diverse materials for study', (3)'Student advisor equipped with a teaching sense of duty and sound humanity', (4)'Curriculum expert equipped with a expertise knowledge', (5)'A fair and democratic schoolroom environment promoter'. (6)'Career path counselling expert understanding student's characteristics and environments'. Through the factor analysis, six RCHET factors are more important to teachers than students. According to importance perception for RCHET, home economics teachers' qualification for minor second subject and participation of training program showed similar differences statistically in all RCHET factors. Thus, effort for expertise improvement of teacher had important influence on expertise improvement of teacher. As a result of examining the differences from importance evaluation for RCHET, similar differences from frequence of home project, preference of home economics teacher, manual training and home economics score, interest of home economics showed statistically.

Failure Mode and Effects Analysis (FMEA) has been used by Dynamic Positioning (DP) system for risk and reliability analysis. However, there are limitations associated with its implementation in offshore project. 1) since the failure data measured from the SCADA system is missing or unreliable, assessments of Severity, Occurrence, Detection are based on expert's knowledge; 2) it is not easy for experts to precisely evaluate the three risk factors. The risk factors are often expressed in a linguistic way. 3) the relative importance among three risk factors are rarely even considered. To solve these problems and improve the effectiveness of the traditional FMEA, we suggest a Fuzzy-FMEA method for risk and failure mode analysis in Dynamic Positioning System of offshore. The information gathered from DP FMEA report and DP FMEA Proving Trials is expressed using fuzzy linguistic terms. The proposed method is applied to an offshore Dynamic Positioning system, and the results are compared with traditional FMEA.

As the Fundamentals of Construction Business Act was revised in December 2004 and its implementing ordinances and enforcement regulations were adjusted in June 2005, the screening system of low price subcontracting has been an obligation to the public owners, having brought about arguments for and against since it enacted in 1983. The statutes for low price subcontracting have been reinforced from this year; for example, it underlines to submit to a project and builds an information network of subcontracting works. The system's original intention was that prevents shoddy and fraudulent constructions caused by low price subcontracting and precludes disturbances of fair trade by screening that whether it satisfies the conditions or not in advance. But, the criterion for the existing low price subcontracting has several issues having held up a true mirror to the real situation. It is arguable to discharge an important task with the primary purpose. This dissertation have researched the problem with a deposit of subcontract and the low price subcontracting basic rate are being used by the criteria for deciding whether it is a low price subcontracting or not, so showing the plan of reformation based on the findings, it wishes to contribute toward making the most of the system's essential intent.
