Purpose - This paper empirically investigates the effect of a rise in the global value chain (GVC) on the industry-level efficiency of resource allocation (based on plant-level inefficiency measures) in Korea, with a focus on various channels through which a rise in the GVC can increase competition among firms and thus induce resources to be allocated more efficiently across firms. Design/methodology - We empirically investigate the relationship between the industry-specific importance of GVC and the industry-level allocative inefficiency that is measured as the dispersion of the plant-level marginal revenue of capital (MRK) as in Hsieh and Klenow's (2009) influential model. We compute MRK dispersion for industries sorted by various characteristics that are closely related to firm/industry sensitivity to the GVC. In other words, we compute the average industry-level MRK dispersion for industries sorted by industry-specific importance of GVC and compute the difference between the two groups of industries (higher vs. lower than the median GVC); we also calculate the difference between industries sorted by industry-specific export (import) intensity. This is our difference-in-difference estimate of the MRK dispersion associated with the GVC for the export (import)-intensive industry versus the non-export (non-import)-intensive industry. This difference-in-difference estimate of the MRK dispersion conditional vs. unconditional on firm-level productivity is then calculated further (triple-difference estimate). Findings - A rise in GVC is associated with a decrease in the MRK dispersion in the export-intensive industry compared to the non-export-intensive industry. The same is true for industries that rely heavily on imports versus those that do not (i.e., import intensive vs. non-intensive). Furthermore, the reduction in the MRK dispersion in the export-intensive industry associated with an increase in the GVC is disproportionately greater for high-productivity firms. In contrast, the negative relationship between GVC and MRK dispersion in the import-intensive industry is disproportionately smaller for high-productivity firms. Originality/value - Existing studies focus on the relationship between GVC and aggregate output, exports, and imports at the country level. We investigate detailed firm/industry-level mechanisms that determine the relationship between GVC, trade, and productivity. Using the plant-level data in South Korea, we investigate how GVC is related to the cross-firm MRK dispersion, an important measure of allocative inefficiency, based on Hsieh and Klenow's (2009) influential economic theory. This is the first study to provide plant-level evidence of how GVC affects MRK dispersion. Furthermore, we examine how the relationship between GVC and MRK-dispersion varies across export intensity, import intensity, and firm-level productivity, providing insight into how GVC can affect firms' exposure to competition in the global market differently depending on market conditions and thus generate trade-related productivity gains.

The main purpose of the research was to prove, in a practical sense, the relationship among perceived equity, role stress and life satisfaction of employed wives working in sales departments. The subjects were employed wives working in sales departments who have at least one child and a spouse, living in Seoul and the Metropolitan area. The final data analysis used 487 out of 668 questionnaires. Statistical analyses were carried out using SPSS/PC WIN which included frequencies, mean, percentages, Pearson's correlation, Cronbach's ${\alpha}$, factor analysis, multiple regression analysis. The findings of the study were as follows: 1) As their education level was low, the education level of their spouse was high, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived emotional relationship was equal. As they were old, the communication level between couples was high, and the self-oriented perfectionism was low, their perceived position in sharing household chores was equal. On the other hand, as they were younger, the education level of their spouse was high, the reason for getting a job lay in supporting the family, and overtime hours worked, there was a higher level of role stress. 2) The influential variables which affect the life satisfaction, in order of importance, were communication level between couples, mother's role stress, age, non-financial reason of getting a job, and sharing household works. For relative contribution degree about life satisfaction, psychological variables among independent variables were revealed as the most influential ones. Thus, efficient communication between couples affected the life satisfaction to a great degree. Furthermore, the study proved that not only role stress variables but also perceived equity variables contributed to the life satisfaction.

Objectives: The purpose of this study was to examine the state of ADHD disposition among college students and the impact of their self-esteem on ADHD in an effort to provide useful information on the prevention of ADHD in adults. Methods: A survey was conducted from April 4 to June 30, 2015, on 264 selected students at two different universities that were respectively located in the Daegu and Gyeongsan city. As for data analysis, a statistical package SPSS WIN 18.0 was employed. Results: The findings of the study were as follows: There were significant differences in overall ADHD disposition according to academic year, religion and academic standing, and self-esteem varied with gender, presence or absence of a friend of the opposite gender, academic year and academic standing. There were differences in inattention-memory problems scores, one of the sub factors of adult ADHD, according to presence or absence of a friend of the opposite gender, academic year and academic standing. Self-esteem had a negative correlation with inattention-memory (r=-0.463), hyperactivity(r=-0.269) and impulsiveness(r=-0.233). When a regression analysis was made to determine influential factors for inattention-memory, religion(${\beta}=0.121$), academic standing(${\beta}=-0.153$) and self-esteem(${\beta}=-0.422$) were influential. Conclusions: Adult ADHD disposition and self-esteem of college students seems to be relationship. There was a positive correlation among inattention-memory, hyperactivity and impulsiveness that were three subfactors of adult ADHD.

With regard to urban culture this study aims to essential understanding and systematic approach to the culture. The "2012 Seoul Survey" report has been used to find out causality among the related variables. In the first place 'satisfaction of cultural condition' was operationally selected as a dependent variable for regression. For the purpose of controlling the third factors for ceteris paribus effect correlation analysis was previously done between the dependent variable and all other variables respectively, which resulted in two groups of variables: group (1) - 2 variables of very significant correlations(p-value<0.01) and (2) - the other 6 variables of significant correlations(p-value<0.05). Then hierarchical regression was adopted to these 2 groups to analyse statistical significance of independent variables, and multicollinearity(VIF; variance inflation factor). Additionally to OLS robust and bootstrapping regressions were done to confirm the validity of this model specification. At last a regression model specified by group (1) as independent variables(they are 'community spirit caring for women, the disabled, the poor and the old,' 'satisfaction of bicycle riding condition' shows that the variables have statistically significant and substantially strong effect on 'satisfaction of cultural condition.' This finding implies the following understanding; (1) urban festivals are regarded as the main of the urban culture as of now and this results from the low level of today's culture, (2) culture is telling and hearing stories but the influential relationship between urban culture and community spirit on the weak is negative, which says that the cultural perception among citizen is somewhat selfish and far from the essential understanding of the urban culture. In spite of restrictive external validity this finding can be used as a direction for promoting culture and a basis for related policy choice in cities.

The purpose of this study was to evaluate the current status of dietary habits and dietary life competency of elementary school parents, who are influential to the dietary life of their children and family. A survey was conducted with 362 elementary school parents living in Seoul and Gyeonggi province by using a self-administered questionnaire consisting of 53 questions on dietary habits, dietary life competency, home cooking frequency, and dietary education needs. The results were as follows: The scores of dietary habits and dietary life competency were 76.35 and 74.51 out of 100, respectively, suggesting a need for improvement. Parents with higher monthly income, demonstrated higher scores of both dietary habits and dietary life competency (p<0.001). As expected, female parents showed higher scores of dietary life competency than male parents (p<0.01). there was also a close relationship between the scores of dietary habits and dietary life competency (r=0.58). The parents with high scores for dietary habits and dietary life competency showed a significantly higher frequency of home cooking (p<0.001) compared to medium- or low-scored parents. Most parents answered that dietary education need to be started earlier, and that their main source of dietary life information was mass media. They also showed a preference for real experience and practice for dietary education. The above results showed that there is a close relationship between dietary habits and dietary life competency, and suggest that continuous education is necessary to improve the dietary habits and dietary life competency of elementary school parents. Because monthly income appeared to be the most influential socioeconomic factor for the parents' dietary habits and dietary life competency, continuous efforts on dietary education are necessary to reduce the score gaps in these categories.

This study aims to measure in-patients' willingness to choose the same hospital, and to define the related factors. The willingness was measured by the fact whether in-patients would return to the same hospital for their future hospitalization and can be said as the essence of ascertaining patients' satisfaction. Data was collected from 236 patients hospitalized in two hospitals selected according to its superiority, one being superior in medical technique, the other being superior in facility and equipment. To enhance the comparability between the two hospitals, the department and the diagnosis were matched, and structured questionnaires were self-fill-up. The main findings are as follows. Hospitals were analyzed by their superiority : medical services, facility and equipment. In case of hospitals with superior medical services, the willingness was proportional to positive doctor-patient relationship, to satisfaction with the medical level, and to the acknowledgement of utility in cure. In case of hospitals with superior facility and equipment, the willingness was proportional to the satisfactory state of overall facility. Two types of hospitals were combined and analyzed. The willingness for choosing hospitals with superior medical services was stronger than that for choosing the other hospitals. The satisfaction with overall facility, satisfaction with medical level, acknowledgement of utility in cure, positive doctor-patient relationship, and better consultation produced higher willingness to choose the same hospital. The willingness for the option shows to what degree the hospital suffices patients' expectation. Patients' understanding views were obviously influential. The satisfaction level for medical aspect was more influential than the level for non-medical aspect.

최근 소셜 네트워크의 2가지 주목할 만한 특정은 바로 정보의 홍수와 정보 소비의 과부하 문제이다. 1990년대부터 상황 인지 기반의 개인화 기법들이나 추천 시스템을 통하여 이러한 문제들을 해결하고자 하였는데, 특히 커뮤니티 멤버간의 신뢰도나 친밀도를 기반으로 개인화 정보를 발견하기 위한 접근방법이 최근 소셜 네트워크가 거대화됨에 따라 그 중요성이 부각되고 있다. 그러나 이러한 대부분의 접근법들은 현실이 아닌 온라인 세계에서의 상호 신뢰도(또는 친밀도)만을 고려하는 경향이 있어 보다 더 높은 개인화 성능(적절성)을 가지기 위해서는 현실 세계까지 고려할 필요가 있다. 본 연구에서는 높은 적절성을 가지는 개인화 정보를 식별하는 새로운 방법을 제시하며, 이러한 개인화 정보를 발견하기 위하여 현실 세계와 온라인 세계에서 정보 제공자와 수신자의 상호 신뢰도를 측정하고 이를 기반으로 정보의 중요도를 판단한다. 그리고 본 기법은 개인에게 신규로 제공되는 정보가 아닌 과거에 소비하지 못하고 놓친 정보들을 대상으로 적용한다.

Purpose : This descriptive research study aimed to investigate the relationship among academic self-efficacy, sleep quality, and quality of life(QoL) and to identify the factors that affect quality of life(QoL) in nursing students during the COVID-19 pandemic. Method : A total of 214 nursing students from three South Korean colleges were included in the study. Collected data were analyzed using the SPSS/WIN 21.0 program. Independent t-test and one-way analysis of variance were used to analyze the differences in academic self-efficacy, sleep quality, and quality of life(QoL) according to general characteristics. In addition, post-hoc Scheffè test and Pearson's correlation coefficient were used to examine the relationship among the three parameters. Stepwise multiple regression analysis was conducted to identify influential factors on the nursing students' quality of life(QoL). Results : The average academic self-efficacy, sleep quality, and quality of life(QoL) scores were 3.15±0.27, 32.28±7.54, and 81.12±13.11, respectively. Quality of life(QoL) positively correlated with academic self-efficacy but negatively correlated with sleep quality. Academic self-efficacy negatively correlated with sleep quality. Sleep quality, satisfaction with major, sex, average income, and academic self-efficacy influenced quality of life(QoL), whose explanatory power was 34.9 %. Conclusion : Sleep quality was the most influential factor of quality of life(QoL). However, further studies to validate our findings and studies focusing on developing intervention programs to improve nursing students' sleep quality and quality of life(QoL) are warranted.
