This study aims to analyze the determinants of residential location choice for the inter-urban migrants in the Seoul metropolitan area. In doing so, we have built a discrete choice model, using household sample data from the 2010 Korea Population and Housing Census. We classified households, which made a intra-urban movement during the last five years, into four groups: 1) movers from Seoul (central city) to Gyunggi-Incheon (suburban), 2) movers from Gyunggi-Incheon to Seoul, 3) Intra-Seoul movers, and 4) intra-Gyunggi-Incheon movers. The analysis findings can be summarized as follows. First, significant differences in the determinants of residential location choice were found among different types of movers. Second, movers from Gyunggi- Incheon to Seoul were likely to choose small housings with fewer rooms, indicating that their housing choices were forced rather than voluntary due to high housing prices in Seoul. Third, all types of movers have a high preference for the neighborhood with a good accessibility by public transit including subway. Lastly, neighborhood amenity was also an important attracting factors for the intra-urban migrants in Seoul.

This study was aimed at identifying the factors of creative ability influencing problem-solving skills for University students majoring in nursing science. A descriptive study was conducted with a sample of 248 students enrolled in a 4-year undergraduate academic program for nursing in one University located in an urban area of Korea. This study used: (a) 25 items of Process Behavior Survey, and (b) 35 items of the Integrative Creativity Scale. The data were collected from Nov. 8th toward Nov. 26th, 2010; the research was conducted through voluntary participation after an explanation about the research. The data were also analyzed with SPSS 18.0 program, using Pearson correlation and stepwise multiple regression methods. Mean score of the level of problem-solving process was 3.62(${\pm}.448$). Problem-solving process was significantly related to creative ability(p<.01). Problem-solving process was significantly influenced by flexibility and elaboration in account for 42.4%. These results imply that in order to foster problem-solving ability, nursing professors need to develop nursing students' creative ability and its factors.

The purpose of this study was to Identify the self-actualization level of Junior College Nursing Students and to analyze the variables that may be related to self-actualization. A convenient sample of 346 students were selected from three colleges located in Seoul and Kyungki-Province. The data were collected using a direct survey method from September17to October 2, 1992. The instrument used for this study was the self-actualization test modified by Kim & Lee(1983). The collected data were analyzed using percentages, means, 1-test, X$^2$-test, ANOVA and Pearson’s correlation coefficient, with the SPSSPC$^{+}$ Package. The results of this study are as follows : 1) The self-actualization level of subjects was moderate. The subjects showed higher scores in the areas of Self actualizing Values and Nature of Man than the standardized normal groups. The subjects showed lower scores in the areas of Inner Directed Existentiality, Self acceptance and Capacity for Intimate Contact. 2) The subjects attending day junior colleges showed higher scores in the areas of Time competent, Existentiality and Self Acceptance than those attending college in the evening. The subjects attending evening junior colleges showed higher scores in the areas of Spontaneity than those attending college by day. 3) The junior students showed higher scores in the areas of Feel-ing Reactivity than freshman. The students with no religion showed higher scores in the areas of existentiality than those who had a religion. The group who had the experience of failure on the college entrance examination showed lower scores in the areas of Nature of Man than those without this experience. Those who chose their major voluntary showed scores higher in the areas of I nor Directed, Self Actualizing Values, Spontaneity and Self regard than the unsatisfied group. The group satisfied with college life showed higher scores in the areas of Time Competent, Inner Directed, Self Actualizing Values and Self Regard than the unsatisfied group. In conclusion self actualization level depends on motivation of choice, satisfaction with nursing as a major and satisfaction with college life. Therefore, and effective guidance program is required to improve motivation and satisfaction with nursing as a major and with college life.

This study investigated the isolation hypothesis and the buffer hypothesis of Demand-Control-Support model in relation to activity satisfaction and psychological well-being. The subjects were 300 elderly women participating in productive activity for example paid work, voluntary activity, and grancdhildren care. This research tested four hypotheses concerning the DCS model. Is there support for the isolation hypothesis, such that the lowest level of activity satisfaction is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the isolation hypothesis, such that the lowest level of psychological well-being is experienced by the elderly women working in an isolation situation(high demand-low control-low support)? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on activity satisfaction? Is there support for the buffer hypothesis, i. e. interaction between demand, control, and support, indicating a buffering effect of support on the negative impact of high strain on psychological well-being? Major results of this study were as follows. and were supported. Activity satisfaction and psychological well-being of the elderly women in isolation situation was the lowest among the sample. was supported that family support level buffered the negative impact of high strain on activity satisfaction. But was not supported. Only main effect of demand level was showed on psychological well-being.

This study examines the characteristics of the online child-rearing community launched by the voluntary motivations of consumers, and the effects of those characteristics on community loyalty and the intentions to buy baby wear via community sites. The study was implemented by a descriptive survey method using an online questionnaire. The sample consisted of 212 members of online child-rearing communities. The data were analyzed by frequency, factor analysis, and regression analysis. Results are as follows. 1) It was found that there were four major factors of online child-rearing community characteristics, such as attachment/pleasure, practical/economy, interaction, and information. 2) All four factors had significant effects on community loyalty. 3) The factor attachment/pleasure had no significant effects on intentions to buy baby wear, but practical/economy, interaction and information had effects upon those intentions. 4) Loyalty to the online child-rearing community had significant effects on the intentions of community members to buy baby wear via the community site. In addition, online child-rearing community members are interested in information regarding baby wear as well as its purchase; this is why baby wear makers should perform cost efficient consumer group segmentation in a timely manner. In addition, it will be effective for their marketing activities to target such consumer groups as segmented.

Sixteen pigs from 2 distinct genetic lines (LGAH and VFIL) obtained after eight generations of divergent selection for high (H) and low (L) lean tissue growth rate with ad-libitum feeding (LGA) and voluntary feed intake (VF1), respectively, were used in this study. The objectives of this investigation were to establish appropriate working conditions for the postheparin plasma lipoprotein lipase (LPL) assay and to study relationships between fat deposition and plasma lipids, very low density lipoprotein (VLDL) lipids, VLDL-subfractions and postheparin plasma LPL activity in growing pigs. Four preliminary experiments were performed to determine the appropriate working conditions for the postheparin plasma LPL assays. Postheparin plasma preincubated with SDS (20-50 mM) at $26^{\circ}C$ for 45 minutes inhibited hepatic lipase activity. A total of $2{\mu}l$ VLDL/assay produced maximum stimulation of LPL activity. Postheparin plasma protein and increasing incubation time contributed an optimum response. LGAH pigs had a significantly higher proportion subtraction 2 than VFIL pigs. No differences were observed in postheparin plasma LPL activity and backfat thickness for two lines of pigs. There were positive correlations between backfat thickness and proportion of subtractions 2 and postheparin plasma LPL activity but the results were not statistically significant. Backfat thickness was not statistically correlated with proportion of subtraction 2 and postheparin plasma LPL activity in a multiple regression analysis. It is believed that the apolipoprotein E, which is present in higher quantities in VLDL-subfraction 2 plays an important role for clearing VLDL triacylglycerol into adipose tissue. LPL activity of pigs can be measured by using postheparin plasma technique. If the relationships of backfat thickness and VLDL-subfraction 2 and postheparin plasma LPL activity can be established, it suggests that these parameters could be used as indicators in selection programmes. Further experiments need to be conducted by using larger sample size and different breed of pigs with greater differences in backfat thicknesses to confirm these trends.

Purpose - This paper investigates whether managerial overconfidence is associated with firm-specific crash risk. Overconfidence leads managers to overestimate the returns of their investment projects, and misperceive negative net present value projects as value creating. They even use voluntary disclosures to convey their optimistic beliefs about the firms' long-term prospects to the stock market. Thus, the overconfidence bias can lead to managerial bad news hoarding behavior. When bad news accumulates and crosses some tipping point, it will come out all at once, resulting in a stock price crash. Research design, data and methodology - 7,385 firm-years used for the main analysis are from the KIS Value database between 2006 and 2013. This database covers KOSPI-listed and KOSDAQ-listed firms in Korea. The proxy for overconfidence is based on excess investment in assets. A residual from the regression of total asset growth on sales growth run by industry-year is used as an independent variable. If a firm has at least one crash week during a year, it is referred to as a high crash risk firm. The dependant variable is a dummy variable that equals 1 if a firm is a high crash risk firm, and zero otherwise. After explaining the relationship between managerial overconfidence and crash risk, the total sample was divided into two sub-samples; chaebol firms and non-chaebol firms. The relation between how I overconfidence and crash risk varies with business group affiliation was investigated. Results - The results showed that managerial overconfidence is positively related to crash risk. Specifically, the coefficient of OVERC is significantly positive, supporting the prediction. The results are strong and robust in non-chaebol firms. Conclusions - The results show that firms with overconfident managers are likely to experience stock price crashes. This study is related to past literature that examines the impact of managerial overconfidence on the stock market. This study contributes to the literature by examining whether overconfidence can explain a firm's future crashes.

Objectives : The purpose of the study was to investigate self-reported oral health attitudes and behaviors among patients receiving scaling services and provide guidelines for developing preventive programs for dental disease. Methods : The survey was administered to a sample of 462 receiving voluntary scaling service in the practice lab in the department of dental hygiene at J health college. Results : 1. Of all participants, 261(56.5%) reported that they received scaling services in the past. 134 of the women (62.6%) and 127 of the men (51.2%) received scaling services 2. Analysis of the regular scaling attendance rates showed that only 16.2% of all participants received routine scaling. 13.7% of the male participants and 19.2% of the female participants received scaling on a regular basis. 3. Participants commonly reported "self-motivation" and "suggestion by others" (37.9% and 34.1%, respectively) as the main reasons for obtaining scaling services. 4. The main reasons for not obtaining scaling services were "I did not know about scaling" (39.3%), "I don't feel it is necessary" (27.4%) and "because I am scared" (20.9%). More men (42.1%) than women (35%) reported that they did not know about scaling. 5. Of the total participants, 41.6% reported that they were concerned about oral health at a moderate level, and 30.3% reported that they were concerned about oral health at a high level. 6. Of the participants who responded "very concerned about oral health" and "extremely concerned about oral health", the majority obtained scaling service (70.2% and 84.2%, respectively). Conclusions : The study suggested that researchers and national health authorities should develop routine scaling, preventive dental care, and oral health programs for oral health promotion and disease prevention.
