A quantitative analysis was conduct on the economic effect of electronic commerce according to the method of constructing the internet. As a consequence, it was information retrieval cost that had the most cost retrenchment effect in connecting the internet by telephone, which saved about 353,700 won. And it was found that the dedicated line to electronic commerce saved 420,600 won of information retrieval cost and a considerable amount of 319,900 won of brokerage expenses and physical distribution expenses. In terms of value, it was found that the telephone line reduced the time of order process by 8.25%, whereas the dedicated line did so by 9.41% and therefore saved more time than the telephone line. It was found that the dedicated line convenient to use had the higher effect by about 1.2%, respectively than the telephone line in terms of the effective construction of corporate image and the increase of potential buyers. In terms of business management, the intensification of corporate competitiveness improved by 10.00% in case of less than 10 times and by 11.53% in case of 50 to less than 50 times. And it was found that the effect of profit increase as the number of inquiries was large. That is, it was found that the effect of profit increase was 10.88% when the number of inquiries was less than 10 times but it increased to 14.00% in case of 50∼1ess than 100 times. The limitation of this study is that because the size of samples through mail, interview and E-mail was not large, its results have some limitation in applying them to every firm. That is, since the improvement effect of the intrafirm business method, unnecessary repeated manual paperwork and the use effect of being able to maintain the close relationship with to the parties to trades in the process of prompt receipt and delivery of documents are long-term and indirect effects, they have some limitation in that they can not be measured as coefficients but only as scales. Thus, firms using electronic commerce have difficulty enjoying a uniformly identical effect. Therefore, to revitalize electronic commerce, it is thought that government, the academic community and the business world all need to make much research into and sustained investment in electronic commerce.

This study was attempted to generate a monoclonal antibody against human $\alpha$-fetoprotein (AFP) and to produce an immunoassay, recognizing AFP in plasma and amniotic fluid. AFP was purified from human amniotic fluid and used to immunize mice. Spleens were taken from the mice and the cells were fused with mouse myeloma cells (Sp2/0-Ag-14) for the production of monoclonal antibodies by employing the hybridoma technology. As a result, a hybridoma cell line producing anti-AFP monoclonal antibody was cloned out and designated as MabF22. From isotyping analysis, it was found that monoclonal antibody MabF22 was IgG type with IgG1 heavy chain and k light chain. The binding specificity of MabF22 was analyzed by immunoblotting as well as by ELISA. MabF22 was highly specific, reacting with only AFP-containing samples. The binding affinity was determined by ELISA (free-capture mode) and Scatchard analysis. As a result, the value of Kd was 0.8$\times$10$^{-10}$M. The validity of the MabF22 for AFP assay was examined by two kinds of ELISAs, i.e., non-competitive and competitive ELISA. Both assays revealed that MabF22 reacted well with AFP in sample in a concentration-dependent manner. Standard curve and antibody titration curve were obtained by using purified AFP and MabF22. These results indicate that the monoclonal antibody produced in this study would be useful not only for research purposes but also for further development of immune-diagnostic kit for the measurement of AEP concentration.

The purpose of this study was to investigate the change of clothes in modem Korean women in terms of a socioeconomical background, the introduction to western clothes, and the improvement of clothes between the opening period of ports in the early 1900's and 1960's. In addition, the study investigated how western clothes became popular in a Korean society along with the traditional' Korean clothes, Hanbok. The radical social change since the opening of ports motivated the change in the way of Korean women's thinking, and consequenty the improvement of Hanbok which developed into the clothes-improvement-movement. It was not until 1905 that the improvement of clothes was hotly debated particularly in the matter of abolishing Jangeui and the extreme length of Jeogori and Chima. The Tongchima-Jeogori style which lengthened Jeogori and shortened Chima was widely accepted as everyday wear until the western clothes substituted them after the Independence from Japanese Conquest. As the length of Chima shortened, there occurred a change in Boson and Jipsin as well. There appeared shoes and Gomoosin in place of Jipsin, socks in stead of Boson and were popularized until after the Liberation in 1945. The popularity of Gomoosin diminished markedly with the diversification of shoes styles, due to the improvement of the standard of living with economic development in the 1960's. The traditional Hanbok was gradually differentiated according to the social status, for instance student, teachers, ordinary women, girls and Kisaeng. Especially since the white clothes caused much trouble in washing and sewing, there came into being the movement of wearing colorful clothes. The Movement of abolishing white clothes and promoting of wearing colorful clothes was enforced during the period of Japaness conquest from the 1920's to the Liberation, which consequently stimulated an interest for colors of clothes. The period under the war between 1937 and 1945 was especially noted for the extreme regulation over the clothes. The Japanese government forced each group of women, e.g., girl students, a young women's association, school teachers, and ordinary women and girls, to wear their own uniforms. Also, It recommended the use of Tongchima in stead of long skirts, and buttons in place of Coreum so as to conserve textile encouraging the use of other substitutes to save resources. The western clothes, a model of clothe's improvement was deemed as a symbol of modernization and enjoyed general popularity. The supply of relief clothes after the Korean war accelerated the expansion of western clothes even further and the trend of westernization along with economic progress in the 1960's resulted in wearing of western clothes as everyday dress. The expansion of western clothes as casual wear rapidly diminished wearing of Hanbok which in turn took the position of ceremonial dress worn in special cases only. Hence the Korean women's clothes were dualized into traditional Hanbok and western clothes and the western clothes that stems on its convenience was settled as everyday wear where as the Hanbok appeared as ceremonial dress stressing on ornamental features. As mentioned aboved, we are able to discovered an orientation in the course of transitional process of modern Korean women's clothes admist diversified changes, which is a consistent pursuit of convenience and practicality based upon progmatism. The trend such as this carne into a finale' as women's dress became dualistic in forms of Hanbok and western clothes, and the change since then is supposed to proceed in two forms of dress featuring its own style.

Background: Oversight on the bioethical compliance of national R&D projects or research personnel is currently conducted exclusively by IRB (Institutional Review Board) within the relevant research institute. Considering current state of affairs in Korea, there is an imperative to establish a national oversight system for bioethical compliance, conduct comprehensive oversight on bioethical compliance of national R&D projects, and enhance subject protection system. Methods: We examined opinions from researchers and IRB personnels regarding ethical oversight system on R&D projects. Additionally, we looked at IRB assessment by KAIRB (Korea Association of Institutional Review Board) in order to identify status and problems with current IRB system in Korea. Assessment was also done for four other countries (US, UK, Germany, Singapore) through in-person visits as well as surveys in writing for a total of 6 months (2012.12.1~2013.5.31). The research comprised of two aspects: system management and R&D project audit. Based on this, we examined current status and problems of the existing system in Korea and made recommendations for improvement. Results: Regulatory objectives and backgrounds of biomedical researches are different from each country due to different characteristics of bioethical oversight system. This shows that each country sets up its own regulations and procedures to fit each situation. Bioethical compliance oversight system greatly varied between the countries. From this study, it can be seen that improvement of existing procedures and oversight system or establishment of new ones are essential in Korea. Conclusion: In terms of system management, a dedicated government organization need to be established for bioethical compliance, subject protection, IRB inspection, training, evaluation, and certification of systems, and also support for IRB e-system. Regarding R&D project oversight, it is essential to confirm IRB review results before start of a research, to conduct a review on ethical aspects of research plans, and to carry out continued oversight on bioethical compliance through interim reports.

Recently EA(Enterprise Architecture) has been receiving growing attentions again from the public sectors. It is because EA maturity result is reflected to the organization's informatization level and EA maturity ratio has been enlarged. There has been more participation from the Chief Information Officers of the public sectors. EA research in the public sectors has influenced IT environment since the research started in late '90, the legislation work done in '05, and the maturity model developed in '06. However, there are some remaining tasks to solve. EA policy is introduction oriented, its contribution to the consecutive the best UN e-Government rank is limited, and its user-friendly responding system is still lacking. Related research outcomes are rather microscopic focusing only on the models and maturity than implicating on the public policy in a macroscopic manner. In this respect, this study will provide the implication on how EA policy should be. Requirements derived from EA stakeholders and the tasks will be arranged in accordance with its domain, then the performance and tasks will be demonstrated. As guiding EA stake holders and information related officers to setup the EA policy with these results, this study is expected to support information the policy drivers.

This experiment was conducted to determine standardized ileal amino acid digestibility (SIAAD) of commonly used feed ingredients in poultry diets in Pakistan. These feed ingredients included corn, rice broken (RB), rice polishings (RP), wheat bran (WB), sunflower meal (SFM), cottonseed meal (CSM), guar meal (GM), soybean meal (SBM) from India and Argentine and fish meal (FM). The SIAAD of each ingredient was determined in triplicate using 21-days-old broilers. Day-old male broiler chicks (Hubbard${\times}$ Hubbard) were reared on corn-SBM based diet from 1 to 13 days and thereafter birds were fed experimental diets from day 14 to 21. Each diet was fed to 36 birds kept in six replicate cages, each cage had six birds. In cereals, the SIAAD of corn's amino acid (AA) (90.1%) was similar (p>0.05) to RB (89.0%). Isoleucine (97.8%) and lysine (96.9%) were highly digestible AA in corn and RB, respectively. Among cereal-by products, WB's SIAAD (76.9%) was same (p>0.05) as RP (71.9%). Arginine from WB (82.5%) and RP (83.2%) was highly digestible. However, threonine in WB (72.7%) and leucine in RP (69.6%) were the lowest digestible AAs. In plant protein meals, AAs from Argentine-SBM (85.1%) and Indian-SBM (83.4%) had higher (p<0.5) SIAAD than other protein meals. However, SIAAD of SFM (77.1%) and CSM (71.7%) was intermediate while GM (60.3%) exhibited the lowest (p<0.05) SIAAD among all ingredients. Arginine from GM (76.9%), CSM (85.8%), SBM-India (89.5%) and SBM-Argentine (91.5%) was highly digestible from indispensable AAs. In SFM, methionine (91.4%) SIAAD was the greatest. The average SIAAD of FM was 77.6%. Alanine from FM had the highest (84.0%) but cysteine (62.8%) had the lowest SIAAD. In conclusion, cereals i.e. corn and RB had higher (p<0.05) SIAAD of the cereals by-products. The SIAAD of RP and WB was same (p>0.05). The SBM from plant protein meals had higher (p<0.05) SIAAD than other studied feed ingredients. However, the GM had the lowest (p<0.05) SIAAD among protein meals.

There is under restructuring of whole distribution market in Mokpo recently. Large-Scale Discount Stores such as E-mart, Lotte Mart, Homeplus and Nonghyup Hanaro Mart entered successfully in the distribution environment in Mokpo. However, the small and medium distributors are falling rapidly, and traditional market is depressed. This status gives some positive effects to make one-stop, good price, good quality and great variety of shopping for saving the time and effort through changing the customers' life-style. This change, however, made the traditional market worse that played as the core channel for trading the local special products and an important role for local economic in retailing market. It is a threatening factor for that traditional market to recover the recession. The decline of traditional market and the bankruptcy of small retailing dealers accelerate the stagnation of local economic and commercial power. Therefore, it need a systematic and synthetical study to solve the negative factors for improving life of the local resident. This paper looked into the concept, issues and development strategy of traditional market that affect local economic development directly. It studied the customers' awareness for traditional market that was recently modernized the facilities in Mokpo. Particularly, based on the research material that was published last academic symposium, it looked about the issues and development strategy that could happen in traditional market not the market of a specific region but all over the country. Therefore, the purpose of this paper is that the central and local government and retailers get a help to make the efficient and useful development strategy through analyzing the effects of customers for modernizing the facilities of traditional market.

Typically, closed-circuit television (CCTV) monitoring is mainly used for post-processes (i.e. to provide evidence after an incident has occurred), but by using a streaming video feed, machine-based learning, and advanced image recognition techniques, current technology can be extended to respond to crimes or reports of missing persons in real time. The multi-CCTV cooperation technique developed in this study is a program model that delivers similarity information about a suspect (or moving object) extracted via CCTV at one location and sent to a monitoring agent to track the selected suspect or object when he, she, or it moves out of range to another CCTV camera. To improve the operating efficiency of local government CCTV control centers, we describe here the partial automation of a CCTV control system that currently relies upon monitoring by human agents. We envisage an integrated crime prevention service, which incorporates the cooperative CCTV network suggested in this study and that can easily be experienced by citizens in ways such as determining a precise individual location in real time and providing a crime prevention service linked to smartphones and/or crime prevention/safety information.
