This was aim to study the changes of components by different parts and maturity of tomato. We found that orally fed tomatine which induced a significant reduction in cholesterol in hamster in contrast to potato glycoalkaloids, the safety of tomatine was supported by our observation that pickled green tomatoes consumed widely in many countries has a high tomatine content. The tomatoes harvested during the first stage(10 days after flowering) contained tomatine $6333.49{\mu}g\;per\;100g$ and dohydrotomatine and ${\alpha}$-tomatine in a ratio of about 1:13.8. The tomatine content then decreased by about 85% during stage 2(20 days after flowering) an dehydrotomatine contene dropped to a value near zero during stage 3, 4 It on the tomatine content dropped to a value near zero during the final stage(50 days after flowering). With respect to health benefits at all stages of maturity, unripe tomato contain chlorophyll and ${\alpha}$-tomatine should consumed.

The purpose of this study is to investigate about security service history as enlightenment period from the provisional government to 1920s. This study used materials by historical facts for the regulations and books in provisional government, newspapers in 1920s. There are four parts conclusion of this study: police department of provisional government, security service agency in the provisional government, security service agents of an independence movement, the general society of Korea. Firstly, Kim Gu, a prominent Korean nationalist leader, was understand of security service which was to protect provisional government from the enemy. So, Kim Gu participated in training of security service agents in the police department of provisional government. Secondly, there was security service agency in the provisional government. In 1920s, security service agency and agents appeared for the first time in regulations of the provisional government. At the beginning of the security service agency's appearance was influenced on background and circumstances for Korean independence activist who helped the independence of Korea from Japan. Thirdly, security service agents leaded an active for independence movement of the private organizations in 1920s. They carried on an independence movement in defiance of Japanese coercion as nationalist in Korea history. Fourthly, security service came out the general society of Korea in 1920s. The security service was not just for safety, but also for its security system and peace of mind, which were influenced by the political situation, social environment in 1920s. For the this reason, now security service has safety perception in Korea despite the historical progress.

The present study was conducted to investigate the general epidemiological situations with 18-pullorum infected chickens from Kyongbuk provinces during the period from June 1995 to January 1996. On the Salmonella pullorum isolation tests by rectal swab culture method from infected chickens (386-samples), any Salmonella spp was not isolated from infected live-birds. But 2-S pullorum were isolated of 2-dead chickens(33.3% ) from 6-dead chickens which were positively reacted by serological tests. On the other hand, we could not isolated any Salmonella spp. in any parts of egg-contents ; egg-shell, egg-white and egg-yolks with 25-infected bird eggs. On the tests of antibiogram, 2-S pullorum strains were highly sensitive to GM, AM, SXT, CZ, K, FIM, ENR, C, AN, N, NN, LIN＋SP, CF, TE and PB, respectively and intermediate sensitive to the CB, CFP, CL, S, P and XNL. But 2-strains were resistant to CC, DP, E, L, OX, TLA and TyLO. In the serological tests, pullorum antibody titers of 18-infected birds was from 2.76 to 9.18 with average by the microplate test. During the 6-months, pullorum antibody average titers were not changed generally. To validate the effects of the antimicrobial agent treatments to the serological antibody titers, infected 6-chickens was medicated with 0.5%-futazolidone. The titer of premeditated birds was average 4.26 but after medication with furazolidone, the titers of treated 6-birds was average 4.08.

The Korean Musk deer (Moschus Moschiferus) is endangered due to heavy hunting and Massive destructions of natural habitat. They are included in CITES appendix II. In addition they are designated as a precious natural product in 1968 and listed as endangered species by the Government and Cultural Heritage Administration. At present, the number of musk deer in Korea is smaller than minimum viable population. Without increment of the population size, natural restoration is impossible. It is necessary to develop the artificial growth and re-enforcement methods in order to conservation Korean musk deer. Furthermore, It is necessary to ensure that we have an adequate individual group for artificial growth and re-enforcement. To ensure that we have an adequate individual group, it is necessary to know ecology of musk deer. This study is conducted to confirm and investigate of habitat of musk deer in order to capture individual musk deer. we investigated, confirmed habitats, found traces and captured using trap and decoy. Captured musk deer is male and 5.5 kg, this have canine tooth of 1.5cm, is estimated 15 months old. After capture, we measured each parts of body and tested to research of parasite infection. Strongyloides papillous was founded in the feces. It is essential to get healthy individual and establish of artificial growth technique.

The study was the second part of the research on development of consumer education program as social education program. The purpose of this study was to analyze needs fur program contents. Program contents had two parts: educational program contents and program managements. The data used contained 617 married women living in Seoul, Korea. Using SAS-PC program, Chi-square and Anova Analyses were executed. The results showed that married women had higher educational needs on housing purchase, tax avoidance, cancellation of contracts after purchase, consumer redress, etc. The differences in age, education, householder's occupation, and household income level resulted in the differences in educational needs for some specific educational items. They were likely to be educated at the highly accessible place such as women's center, community center, University extension service center, and consumer organization, etc. Also they preferred to be educated once a week fur a short time period like one to three months, and to have the lectures with discussion in the class. Some implications were mentioned for developing consumer education program as social education.

Recently, with the development of technologies for the fourth industrial revolution, convergence and complex technology are being applied to aircraft, electronic home appliances and mobile devices, and the number of parts used is increasing. Increasing the number of parts and the application of convergence technologies such as HW (hardware) and SW (software) are increasing the No Defect Found (NDF) phenomenon in which the defect is not reproduced or the cause of the defect cannot be identified in the subsequent investigation systems after the discovery of the defect in the product. The NDF phenomenon is a major problem when dealing with complex technical systems, and its consequences may be manifested in decreased safety and dependability and increased life cycle costs. Until now, NDF-related prior studies have been mainly focused on the NDF cost estimation, the cause and impact analysis of NDF in qualitative terms. And there have been no specific methodologies or examples of a working-level perspective to reduce NDF. The purpose of this study is to present a practical methodology for reducing NDF phenomena through data mining methods using quantitative data accumulated in the enterprise. In this study, we performed a cluster analysis using market defects and design-related variables of mobile devices. And then, by analyzing the characteristics of groups with high NDF ratios, we presented improvement directions in terms of design and after service policies. This is significant in solving NDF problems from a practical perspective in the company.

To vitalize the link program of Korean long-term care insurance system to community-based services for non-eligible people, we analysed the claim data from the Korean National Health Insurance Corporation (NHIC), and conducted a questionnaire survey to charging employees of elderly service department at local governments. The subjects were all 81,377 people, 57,454 of them were arranged to community-based services. The link program was more necessary among the missed subjects rather than the arranged people due to the need for physical or psychological assistance. By the result of the survey to the local government employees, 59.5% of subjects responded their proportion of link service was over 10% and under 20%, and 54.3% of them responded their job boundary are not clear. Major type of linking was notification the subject list to local government, 91.4%; proportion of periodical notification on the status of their service link were 57.1%, only 7.1% were followed to manage after the link. Difficult factors at the link process were pointed out the overload by other side work, deficiency of resources, rigidity of priority of link, and so on. Considering these results, to vitalize the community-based services to the non-eligible people, it may be essential the active participation of the subjects, construction of parts working in coordination among the institutions including NHIC, local governments, and service providers; development of various services for maintenance or promotion of the non-eligible peoples' health and functional status; and active participation of institutions from the third sector, and so on.

The perspectives of customers and providers as for the services have the same objective; however, perspectives and objective are distinctly different. But the existing methodologies have mostly pondered only based on the customer-centric perspective or separately from the perspective of providers. It would be necessary to take these two perspectives as a whole by combining them into one perspective since they not only have differences but also common points. Therefore, in this study suggested the System Journey Map in terms of internal staff based on the customer's task in service. System Journey Map is consists of four parts : a customer journey map, thus the performance of internal staff, internal staff satisfaction evaluation, and finally the performance of internal staff assessment of the senior staff. After releasing a service, with customers and internal staff made a point of contact to identify specific behavioral patterns and whether any part of the problem so that this toolkit gives us an expectation to be a useful map, which is the intangible being placed in service, not just visualize and understand for identifying problems.

Due to the numerous environmental factors, cracks and corrosion are frequently occured especially in old steel bridge, which deteriorate the structural integrity; thus bring about the problems of structural safety of the steel bridge. Therefore, repair and reinforcement are required for the damaged structure. the replacement repair welding method is spotlighted for its brilliant features, i.e. it can be achieved without incurring traffic dislocation. the method cuts the damaged parts and replaces them with new steel plate by welding under live loads. However, the mechanical behavior of the welded joints under cyclic loads due to the traffic which passes along bridge is not clarified. In this paper, the fatigue strength of the replacement repair welded joints was investigated in order to improve reliability in the repair welded joints of old steel bridge.
