Despite the importance of the needs assessment activities and the necessity of the systematical investigation on the features of the needs assessment in the social service agencies, it has been observed that the recent NA studies have ignored an important study area of NA, the utilization of needs assessment results in social service agencies. Therefore, this study was undertaken to investigate salient features of the utilization of community needs assessment results, particularly, in the social welfare centers located in Seoul city. A questionnaire was constructed with seven parts, including a dependent variable and 6 independent variables, and 67 questionnaires were collected from 90 agencies during two months. As the result of the descriptive analyses, the five noticeable features were found; (1) the needs assessment results in the agencies was not highly utilized; (2) the attitude on the NA activities was not highly positive because the responders thought that NA activities require too much time from agency staff; (3) agency staff was more actively involved in the NA process than agency directors; (4) the responders thought that quality of NA influences on the utilization of NA; (5) the respondents were confident in carrying out NA although they did not have many opportunities to learn the technical skills of NA research. Multiple regressions were applied to analyze the relationship between independent variables and three kind of dependent variables - conceptual utilization, instrumental utilization, total utilization. The result showed that the conceptual utilization was critically influenced by social workers' confidence on NA, attitude on NA, and directors' involvement in NA. The institutional utilization was influenced by the directors' involvement. The total utilization was influenced by social workers' attitude on NA, confidence on NA, and directors's involvement. Major findings were discussed and several suggestions were made for future research and improvement of the utilization of needs assessment result in social welfare centers.

The control of stem length is most important external quality aspect in cut chrysanthemum. The present work in conducted in growth chamber and aims at investigating the effect of light intensity on the photosynthesis capacity and stem elongation in cut chrysanthemum. To evaluate the effect, different level of assimilation lighting (LEDs) was given to canopy level 60, 100, 140, and $180mol{\cdot}m^{-2}{\cdot}s^{-1}$, individually, under short-day conditions, and the light treatments were initiated from 7days after planting. There was a positive linear-regression relationship between the light intensity and the net assimilation rate. On the other hand, there was not significant difference in flower buds induction. The growth of stem length, leaf area, and dry weight was increased by increasing the light intensity, whereas the plants grown under 140 and $180mol{\cdot}m^{-2}{\cdot}s^{-1}$ was not differences in those of growth. It indicates that the increased net assimilation rate is not continually coincided with the maximized growth in cut chrysanthemum. It might be considered that the optimal light intensity for stem elongation of cut chrysanthemum is $140mol{\cdot}m^{-2}{\cdot}s^{-1}$ under short-day condition.

In order to research the effects that indoor plants of apartments in Seoul have on the happiness index, we tried to analyze relationships between indoor plants which are nearest to the residents and happiness which is the final goal of the residents, and for this 200 residents who live in apartments in the Seoul city area were sampled. This study was based on the precedent studies of the facts that horticultural therapy and function of plants had already proven the affirmative roles of plants to people. The results were as follows. Residents reported that they were happiest when the plants were blooming(57%), when the plants were sprouting(33%), when repotting(2%), when distributing(2%) and others(7%). The residents exposed to indoor plants were in direction proportion to the happiness index within 1hour. Happiness indexes of the residents who cared for potted plants were by themselves was 67.90, when family members cared for the plants, 65.09, and when others cared, it was 64.79. The preference of indoor plants and the happiness index according to the scale of interior gardens were in direct proportion. Lastly, the happiness index of residents according to the number of potted plants, was in direct proportion: the more potted plants, the greater the happiness index.

China's independent college approved private education investment, and facilitates the use of funds to support individual investors, corporations, and society. In contrast to China's public universities, the college guarantee private school method of operation. Its bachelor's degree, admission to students, the establishment of a separate corporation, and the recognition of scholastic achievements, was established with the aim of ensuring the diversity of higher education institutions in China. However, since the early 1990s, the independent college, which has emerged as a new way of higher education in China, has achieved quantitative growth over the past 30 years, but the quality of education has not yet grown. The reason why the independent college in China is interested is that it receives support from the facilities and professors of the original public college, and the major in which it is established and shares the reputation of the university. This study tried to analyze the policy of independent college which is a unique higher education institution in China. For this purpose, we use Four-Dimensional Framework to analyze the problem of China's independent colleges. It examines the profitability and non-profitability of independent college as a normative dimension and analyzes the Chinese society that have the old "guanxi" culture core in China. On the structural dimension, we analyzed the structure of the relationship in educational administrative institution. On the constituentive dimension, we observed that the various stakeholders who are interested in the independent college policy. Finally, we searched for future directions of the independent college centered on the process of legalization of independent colleges in technical dimension. The results of this analysis suggest the implications of the direction of China's independent college policy.

To continue the growth of use of 5-star hotels by Koreans, who have recently shown the consumption trends pursuing the empirical value of a consumption process, and have turned into core customers of 5-star hotels in Seoul, it is necessary to study factors of experience value pursued by Koreans. As a result, fantasy is identified as a major leading factor in usage satisfaction among experiencial values. So it is important to reflect special concepts and atmospheres for emotional values, such as other world experience, new experience, and high-quality experience. And consumer return on investment was identified as a leading factor in positively affecting usage satisfaction. So it is important to develope a proper products that can enough benefits with reasonable prices. In the relationship between usage satisfaction and continuous usage intention, gender characteristics and occupational characteristics were found to play a moderating role. Male customers, and those with professional and self-employed occupations, were found to have higher continuous usage intention than females and other occupational customers. This is a result of the fact that customers with an economical power are likely to be continuous repeat customers of 5-star hotels, so the necessity of strengthening marketing activities such as research on the development of more differentiated and specialized products, service creation and atmosphere production for excellent consumers group.

This study conducted a sediment culture experiment to investigate the effects of sediment oxygen demand (SOD) and environmental factors on sediment and water quality. We installed a leaching tank in the laboratory, cultured it for 20 days, and analyzed the relationship between P and Fe in the sediment. As a result, the dissolved oxygen of the water layer decreased with time, while the oxidation-reduction potential of the sediment progressed in the negative direction to form an anaerobic reducing environment. The SOD was measured to be 0.05 mg/g at the initial stage of cultivation and increased to 0.09 mg/g on the 20th day, indicating the tendency of increasing consumption of oxygen by the sediment. The change is likely to have caused by oxygen consumption from biological-SOD, which is the decomposition of organic matter accumulated on the sediment surface due to the increase of chl-a, and chemical-SOD consumed when the metal-reducing product produced by the reduction reaction is reoxidized. The correlation between SOD and causality for sediment-extracted sediments was positive for Ex-P and Org-P and negative for Fe-P. The analysis of the microbial community in the sediment on the 20th day showed that anaerobic iron-reducing bacteria (FeRB) were the dominant species. Therefore, when the phosphate bonded to the iron oxide is separated by the reduction reaction, the phosphate is eluted into the water to increase the primary productivity. The reduced substance is reoxidized and contributes to the oxygen consumption of the sediment. The results of this study would be useful as the reference information to improve oxygen resin.

In order to examine cause-specific mortality in Korea by comparing mortality of Japan, various mortality indicators are calculated using 1995 of ficial statistics of twonations. The mortality measures are cause-specific mortality rate by sex, age, andmarital status, cause-specific age-standardized death rate and potential years of lifelost, and their ratios by sex and nation. Items of major causes of death include allcauses (total deaths),tuberculosis, malignant neoplasm, diabetes mellitushypertensive diseases, heart diseases, cerebrovascular diseases, liver diseasestransport accidents, and suicide. Major characteristics of mortality in Korea are asfollows . (1) Death rates from most causes except suicide are higher in Korea thanJapan and especially death rates from tuberculosis, hypertensive diseases, liverdiseases, and transport accidents are higher for economically active Koreans : (2)Death rates from tuberculosis, liver diseases, transport accidents, and malignantneoplasm are salient for Korean children (3) Sex-differentials in mortality fromliver diseases, tuberculosis , and transport accidents are large for economically activeKoreans, because male mortality is higher than female mortality : (4) Suicide ratesare lower for economically active males, and higher for females aged 10s and 20s inKorea than Japan : (5) Death rates are highest f3r divorced or widowed under 45years of age depending on causes, but death rates from all causes are highest fornever-married of the age 45 and over in Korea : and (6) Sex-differentials inmortality are greatest for widowed in Korea and for divorced in Japan.

This study was aimed to understand the recognition of care robots which would enhance the medical quality of life under the 4^th industrial revolution in the university students majoring in health and engineering who would lead the development of the future medical industry and to find out the differences of their digital literacy and empathic ability. This was a descriptive correlation study to analyze the recognition of university students on care robots, their digital literacy and empathic ability. Both students majoring in health and engineering recognized the needs of care robots, while their education experiences were not sufficient. Moreover, statistically fewer university students majoring in health heard about care robots than those in engineering, and their need of taking classes was lower, too. No statistically significant differences were found in digital literacy and empathic ability between the two majors, while significant difference was found in the relationship bundling capability out of behavioral empathy, a sub-domain of empathic ability. The study results are anticipated to suggest the future educational direction in the medical field according to the 4^th industrial revolution and to be the fundamental data for understanding and preparation of the students depending on the majors.

Hanwoo and Chikso are classified as Korean native cattle breeds that are currently registered with the Food and Agriculture Organization. However, there is still a lack of genomic studies to compare Hanwoo to Chikso populations. The objective of this study was to perform genome-wide analysis of Hanwoo and Chikso populations, investigating the genetic relationships between these two populations. We genotyped a total of 319 cattle including 214 Hanwoo and 105 Chikso sampled from Gangwon Province Livestock Technology Research Institute, using the Illumina Bovine SNP50K Beadchip. After performing quality control on the initially generated datasets, we assessed linkage disequilibrium patterns for all the possible SNP pairs within 1 Mb apart. Overall, average $r^2$ values in Hanwoo (0.048) were lower than Chikso (0.074) population. The genetic relationship between the populations was further assured by the principal component analysis, exhibiting clear clusters in each of the Hanwoo and Chikso populations, respectively. Overall heterozygosity for Hanwoo (0.359) was slightly higher than Chikso (0.345) and inbreeding coefficient was also a bit higher in Hanwoo (-0.015) than Chikso (-0.035). The average $F_{ST}$ value was 0.036 between Hanwoo and Chikso, indicating little genetic differentiation between those two breeds. Furthermore, we found potential selection signatures including LRP1B and NTRK2 genes that might be implicated with meat and reproductive traits in cattle. In this study, the results showed that both Hanwoo and Chikso populations were not under severe level of inbreeding. Although the principal component analysis exhibited clear clusters in each of the populations, we did not see any clear evidence that those two populations are highly differentiated each other.
