Purpose: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. Methods: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. Results: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system ($x^2$=13.89, p<.001) were significant, while the differences in the perception of depression ($x^2$=.02, p=.891) and coping methods ($x^2$=.34, p=.558) were not statistically significant. Conclusion: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

The present study was investigated combustion characteristics of methane-air mixtures at stratified charge in a constant volume combustion chamber. The main results obtained from this study can be summarized as follows. In case of ${\phi}_s=1.0$, total burning times greatly affected rather than initial time of pressure increase and maximum combustion pressure. In case of ${\phi}_t=1.0$, initial time of pressure increase and total burning times were affected considerably in comparison with the case of ${\phi}_s=1.0$. Also, even the very lean mixture which total equivalence ratio is ${\phi}_t=0.69$(${\phi}_s=1.0$, ${\phi}_m=0.65$), by changing configuration of the critical passage-hole and using a stratified mixture, it is possible to decrease substantially the initial time of pressure increase. total burning times and NOx concentration without deteriorating combustion characteristics such as maximum combustion pressure, rate of heat release etc. in comparison with the use of single chamber(in case of ${\phi}=1.0$) only. Specifically, our trends were revealed remarkably in the case of Type D which is reduced a flame contact area of sub-chamber side of the passage-hole.

This paper aims at identifying the desirable R'||'&'||'D life cycle related to government-industry cooperative R'||'&'||'D. It is based on a case study associated with the relationship between cooperation and cooperation in information in information communications sector. It presents three types of R'||'&'||'D life cycle to achieve a technological enhancement as high as possible with limited resources. The first case of R'||'&'||'D project is of "advanced type". In the generic technology phase, government takes a leading role jointly in R'||'&'||'D activities, but, in after the applied research phase, the domestic firms take the lead. This kind of cooperation can be made when competition between domestic firms is highly intense, and the technological knowledges of participating firms are at internationally competitive levels. The second type of "less-advanced type"; the firms of a country(more often a small country) lag behind in technology level, and the penetration of foreign firms in the market is limited. In this case, government takes full charge of R'||'&'||'D activities up to the applied research phase, due to the low technology level and insufficient financial resources of private firms. Lastly, this paper presents and R'||'&'||'D life cycle of "strategic" type. This applies to the case in which domestic firm with less financial resources make an attempt to increase their technological knowledges while the government, in turn, contributes to strengthen the international competitiveness of domestic industry.

In order to investigate the fatty acid composition of Korean pumpkins, this study was designed. Three samples of Korean pumpkins, A(yellowish ripe), B(unripe, 30 days old) and C(unripe, 20 days old) were used for fatty acid analysis by gas chromatography. The results were as follows : Pumkin C, B and A showed 10, 12 and 15 kinds of fatty acids, respectively. In case of palmitic acid(C16:0), pumpkin C, B and A showed 22.5%, 22.9% and 26.6%, respectively. In case of u linolenic acid(C18:3), pumpkin C, B and A showed 22.6%, 23.6% and 44.8%, respectively. In case of palmitoleic acid(Cl6:1), pumpkin C. B and A showed 12.4%, 10.1% and 0.5%, respectively. In case of oleic acid(C18:1), pumpkin C. B and A showed 9.2%, 7.7% and 2.8%, respectively, In case of stearic acid(C18:0), pumpkin C, B and A showed B.S%, 3.7% and 3.5%, respectively. The ratio of P/S was 1.4, 1.6 and 1.9 for sample C, B and A, respectively. The ratio of w-3/w-6 was 1.1, 0.9 and 2.6 for sample C, B and A, respectively. Through this study, the ripe pumpkin(sample A) was thought to be good enough in nutritional aspects of fatty acids, particularly a-linoleic acid, Cl8 : 3(u-3) series.

In case high strength steels are applied for press-formed automotive parts, it is very difficult to secure forming accuracy due to large springback compared to moderate strength steels. In this study, a repetitive step-wise forming analyses based on secant method was proposed as the die design method for mandrel(bending tool) for the 2-axis bending equipments. A bending die with circular mandrel was designed for the DP780 blow motor case of which diameter and thickness are 70.8mm and 2.0mm respectively. Forming tests were performed to verify the validity of established die design and the results were compared with that of conventional HGI(Hot galvanized iron steel) blow motor case. For additional improvement in forming accuracy, an elliptical mandrel was proposed and its validity was verified using forming analyses based on secant method.

This study investigated the luring effect of the sardine bait, which is used to catch octopus with pot, as the preliminary study for the development of alternative bait for octopus pot. The soaking time for bait was divided into "5 days or less" and "11 days or longer" The number of times octopus entered the pot with bait and the empty pot was investigated under dark adaptation and light adaptation processes and the distribution of tank section was investigated under light adaptation process. The case of "11 days or longer" sardine soaking time showed higher rate of distribution in the section of pot with bait compared to the case of "5 days or less" In the case of "5 days or less" soaking time, the number of times the octopus entered the pot with bait was similar to that it entered the pot without it even during dark adaptation and light adaptation. However, in the case of "11 days or longer", the octopus entered the pot with bait more quickly than the pot without bait and more frequently during dark adaptation hours. There were cases where the octopus did not enter any pot. In the case of "5 days or less", with less decomposition of baits, the octopus entered the empty pot more during light adaptation process, and it appeared that the pot was used as a hideout.
