The purpose of this study was to propose the strategy for increasing the merchandising power of the SPA brand to improve the competitiveness of domestic fashion industry. A questionnaire survey was administered to 270 SPA brand customer who live in Seoul Metropolitan area and Gyeongi-do area. 240 data were analyzed by factor analysis, t-test, crosstabs analysis, and one-way ANOVA using SPSSWIN 12.0 program. The result were as follows: Importance of store attributes were categorized in five factors: store environment, service, product sales promotion, and convenience. A consumer's the importance of store attributes was significantly different depending on that consumer's demographic characteristics(major, grade etc..) and general product purchasing characteristics(purchasing expense). This result should not be interpreted by expanding to the whole group of the consumer in SPA brand, as the sample used in this study is limited to those in Seoul and GyeongGi area.

The second generation of stars in the globular clusters (GCs) of the Milky Way (MW) exhibit unusually high N, Na, or Al, compared to typical Galactic halo stars at similar metallicities. The halo field stars enhanced with such elements are believed to have originated in disrupted GCs or escaped from existing GCs. We identify such stars in the metallicity range -3.0 < [Fe/H] < 0.0 from a sample of ~36,800 giant stars observed in the Sloan Digital Sky Survey and Large Sky Area Multi-Object Fiber Spectroscopic Telescope survey, and present their dynamical properties. The N-rich population (NRP) and N-normal population (NNP) among our giant sample do not exhibit similarities in either in their metallicity distribution function (MDF) or dynamical properties. We find that, even though the MDF of the NRP looks similar to that of the MW's GCs in the range of [Fe/H] < -1.0, our analysis of the dynamical properties does not indicate similarities between them in the same metallicity range, implying that the escaped members from existing GCs may account for a small fraction of our N-rich stars, or the orbits of the present GCs have been altered by the dynamical friction of the MW. We also find a significant increase in the fraction of N-rich stars in the halo field in the very metal-poor (VMP; [Fe/H] < -2.0) regime, comprising up to ~20% of the fraction of the N-rich stars below [Fe/H] = -2.5, hinting that partially or fully destroyed VMP GCs may have in some degree contributed to the Galactic halo. A more detailed dynamical analysis of the NRP reveals that our sample of N-rich stars do not share a single common origin. Although a substantial fraction of the N-rich stars seem to originate from the GCs formed in situ, more than 60% of them are not associated with those of typical Galactic populations, but probably have extragalactic origins associated with Gaia Sausage/Enceladus, Sequoia, and Sagittarius dwarf galaxies, as well as with presently unrecognized progenitors.

The purpose of this study is to assess naturalness of each and use type for Daegu and provide the basic data for urban green space planning. The results are as follows: 1) As a result of periodic analysis, It is known that in the 1400´s that the rate of a-/oligo-/meso-hemeroby was over 90% of that area, in which naturalness was very high. By the 2020´s, the population will increase to about 3,500,000 and the occupation rae of meat-and poly-hemeroby, where naturalness is very low, is expected to increase rapidly. 2) The recent land uses of Daegu are divided ito 17 types. In the survey of a occupation rate of each land use type, a forest are occupies 48.8% of the entire area. The military installation zone is lowest with 0.07%. 3) Investigation of a dominant hemeroby grade in each land use type showed that the urban complex area in characterized by meta-hemeroby : and the space for pavement and building construction where naturalness is lowest. On the other hand, oligo-hemeroby that is worth being preserved was surveyed to be dominant in woodlands and natural forests. 4) In the analysis of hemeroby mapping in the process of a green space planning, it is clear that hemeroby will be used a s a tool that assesses the suitability for recreation activity of each sample case. For example, it enables a poly-hemeroby region to be utilized as a near-natural recreation area including $\beta$-and $\alpha$-euhemeroby region in Daegu. Besides, hemeroby can provide basic data to make a value judgement of each sample case with a view to preservation of nature.

This study is designed to identify the changes of the elderly's residential environment and life satisfaction in rural area during the past 20 years. Data from the survey of Ministry of Health and Welfare conducted in 1994, 1998, 2004, 2008, and 2014 were used for the analysis. The subjects of the study included a sample of 11,019 respondents who represent aged 65 and older in Korea rural area. The result of analysis indicated that; First, the average age of the rural elderly continuously increased and the rural elderly that hope to live with their grown-up children gradually declined. It means that the social responsibility of supporting the elderly is steadily expanding. Second, the ratio of rural elderly living with their children is decreased from 43% in 1994 to 11% in 2014, whereas the single elderly household who are living alone or living with spouse increased. And more elderly live with married children in order to help their children rather than receiving help from them. Third, the frequency of intercourse with their children tended to decline gradually, in contrast with communication frequency with them mounted steadily during the past few decades. Finally, the factors influencing the life satisfaction of rural elderly was health status, economic level, child relationship with them, and residential environment.

The purpose of this study is to analyze the characteristics and changes of elderly households in rural area. The elderly were classified as elderly living alone, elderly couple living together, and elderly living with their children. Data from the survey of Ministry of Health and Welfare conducted in 1998, 2008, 2017 were used for the analysis. The subjects of the study included a sample of 9,401 respondents who represent aged 65 or more in Korea. The result of analysis was as follows; First, over the past 20 years, there has been no significant difference in the composition of the sexes of elderly in rural area, and aging is becoming more serious. Second, elderly living with children continue to decrease, and elderly couple are increasing. The number of elderly living alone is on the increase, but it tends to decrease in 2017. Third, the proportion of houses in elderly households is still very high, but it is gradually decreasing and the proportion of apartments is increasing. Fourth, the frequency of communication with children tended to increase slightly in all household types, while the frequency of encounter decreased slightly in 2008 and then increased in 2017. Fifth, the health status and economic status of the elderly have been gradually improved over the past 20 years. Finally, the emotional support in all elderly households is maintained constantly, but the instrumental support is gradually weakened.

Purpose: This study was conducted in order to investigate the incidence and associated factors of suicidal ideation among the elderly according to residence area. Methods: This cross-sectional study used secondary data from the 2011 Korean National Health and Nutrition Examination Survey (KNHANES V-2). A representative sample of 1,464 men and women aged 65 and over was selected. Rao-scott $X^2$-test, multiple logistic regression models based on sampling scheme of the data were used. Results: Of the 1,464 respondents, 22.4% had experienced suicidal ideation during the past year. Higher incidence of suicidal ideation was observed in rural seniors (23.7%) than in urban seniors (21.1%). The incidence of suicidal ideation showed correlation with age, education level, depression, stress, lying in a sick bed, and current smoking status among elderly living in urban areas. However, among elderly living in rural areas, the incidence of suicidal ideation showed correlation with household income, depression, stress, and daily activity. Conclusion: Based on the results, nurses should manage effective and individualized nursing interventions for elders in planning suicide prevention programs with consideration for residence areas, because there were differences in the factors affecting suicidal ideation among elders according to residence area.

This study was conducted for an understanding of a threatened plant species,“Penthorum chinense”, which is a vegetation structure and environmental characteristic in the southern part of Ibaraki, Japan. We selected distribution and contiguity area where P. chinense is not distributed and we set up 69 sites by the quardrat method. The surveyed general characters in each site include mean-height, mean-coverage, moisture condition water depth coverage and depth of litter layer. We calculated the degree of succession by the survey data and grasped the main distribution area, vegetation structure, growth environment of P. chinense by TWINSPAN classification and DCA ordination. The results of this study are as follows. First, P. chinense habitat was categorized into the riverside and abandoned paddy fields. The riverside was influenced by natural disturbance caused by flooding and drought. These conditions led to a poor P. chinense growth. The abandoned paddy fields as the artificial disturbance area have high potential value, because the area can preserve P. chinense growth space by succession control and water management. second, we executed TWINSPAN analysis based on vegetation coverage data of survey sites. The vegetation types were classified into the three categories: annual plant flora(P. chinense dominates in wet state), perennial plant flora(Solidago altissima dominates in dry state), and perennial plant flora(Phragmites communis dominates in wet state). Third, the data was ordinated by DCA. The sample sequences along the first and second DCA axes effectively reflected moisture condition, number of species, mean height, coverage of litter layer and degree of succession. Especially, P. chinense flora has the high correlation with moisture condition and number of species.
