Purpose - This is a comparative study of the market development and characteristics of Ulsan in South Korea, Fukuoka in Japan, and Yanji in China, which are major East Sea Rim cities with adjacent areas of similar natural characteristics of the sea and the country. Particularly, it considers these aspects while focusing on the evolution of networks that appear in the distribution system and at the same time examining the institutions of market activation and regulations that are handled by the central and the local government and the changing logistics due to the development of transportation and the concern of food safety, using a meso-analysis approach. Research design, data, and methodology - The study used a historical and comparative approach with a focus on case studies. It made use of various materials such as local newspaper articles, reports, literature, interviews with experts, discussions with local merchants, discussions with customers, and so forth. Results - In the case of Fukuoka, from the 1960s, due to the entry of supermarkets, supermarkets expanded and they have now come to a dominant market position in the current market. They offer a convenient and comfortable environment while providing a large mall offering a variety of educational and cultural activities for customers to meet the customers' needs, such as the preferences of Korean tourists, who appear to prefer Japanese foods. The Fukuoka City Central Wholesale Market has been exporting fruits and vegetables as well as seafood products to Korea, China, and so forth. In the case of Ulsan, as in the early 2000s, due to the expansion of supermarkets, the traditional markets have been shrinking and further, the modernization of traditional markets was conducted under the auspices of the Small Business Administration. In addition to the large discount malls, the expansion of SSM is expected to further drive the small trader bay. Shopping malls, department stores, and traditional markets contend with each other in Yanji, China, but a large number of citizens appear to prefer traditional markets and imported milk in the supermarket after the melamine scandal in China. Recently, the WanYuan (萬源) wholesale market has been partially completed and made an attempt to become a logistics hub in Northeast Asia. Conclusions - For the development of Korea's retail industry, it is important to offer the government with proposals regarding desired regulation. On the other hand, in order to enable the business of traditional markets, it requires an association for cultural tourism. At present, it would be better to provide a venture fund for the youth rather than infrastructure support. This study emphasizes the importance of institutions and policy to develop networks in the East Sea Rim. Future studies should conduct a survey on customers, managers, and merchants more carefully and systematically to understand the market situation while considering the size of the city and its evolution of markets, as well as policies and institutions.

This study analyzed the latent profile for identifying the difference in the dependence on smartphone use among middle school students in the 1st grade using the Korean Children and Youth Panel Survey (KCYPS). From the result of this study, first the latent class was separated according to the type of dependence on smartphone use. Class 1 included the students (from fifth grade in elementary school) whose level of reliance on smartphone use was low. Class 2 was selected as the group whose level of reliance on smartphone was high. Secondly, in comparing class 2 to class 1, it was found that the students who have a high probability of being in class 1 were those whose fathers are high achievers, have high early self-esteem and less age attachment. Thirdly, the students in class 1 had a higher sense of neglect than those in class 2. Furthermore, the self-determination of the students in class 2 mediated the effect of neglect on the adolescents' dependence on smartphone use both directly and indirectly.

The purpose of this study is to examine the importance of entrepreneurs' well-being, and to propose several ways to improve it. First, the factors influencing entrepreneurs' well-being were explored via previous literature review, and positive psychological capital based on positive psychology was selected as the main factor. In addition, the hypotheses were formulated and the research model was constructed by selecting authentic leadership, mastery goal orientation, and social support as the antecedents predictably associated with positive psychological capital. To empirically analyze the proposed model, a questionnaire survey was conducted for the entrepreneurs who fulfilled the training/coaching/consulting programs offered by the Youth Startup Academy. By using the collected 133 responses, PLS-Structural Equation Analysis, PLS-Multi Group Analysis(MGA), and PLS-Importance-Performance Map Analysis(IPMA) were performed. As a result, it was found that positive psychological capital had a high causal relationship with the well-being of entrepreneurs; and authentic leadership and mastery goal orientation had a positive effect on positive psychological capital. However, the statistical significance of the impact of social support has not been verified. While differences in causality between early and growing stages of start-ups only acted as sub-factors of positive psychological capital, the aforementioned three antecedents showed a significant difference for hope and optimism, respectively. This study expanded the topic of entrepreneurship-related research, which mostly focuses on identifying the performance factors of start-ups. It is meaningful in that it empirically verified the causality model constructed by exploring the factors with respect to the mental well-being of entrepreneurs, which is a main theme in the entrepreneurship-related research. These results found in the current study will render practical insights to entrepreneurs, researchers, and educators.

The purpose of this study were to identify the effect of thesis-writing activity based project method on the ability of girl's middle school student's self directed learning(SDL) and learning attitude. To achieve above study purpose, the subject of this study were selected 60 from second-grade students of reading club(thesis-writing activities participants 30, non-participants 30), applied a program based project method to experimental group, to carry out a pre-post examined targeting two-group with early making a SDL ability and learning attitude inventory, and the results of the data were analyzed by t-test using the SPSS(Ver. 18). The results were as follows: In the aspect of SDL ability development by thesis-writing activity, the student participant showed somewhat significant differences compared to the non-participants. First, a openess, inner-motivation, autonomy, self-conception of SDL ability was significantly higher than those non-participants. Second, confidence, success expert, attention, effectiveness, affection of learning attitude was significantly higher than those non-participants. These results represent that various programs, which can develop SDL ability and learning attitude, can be provided for youth when they join any thesis-writing activity based project method in general and those programs are also very effective in developing SDL ability and learning attitude of juveniles. Furthermore, It is suggested that thesis-writing activity based project method are a necessary element at the school education fields.

Aggressive driving is a major cause of car accidents. Previous studies have mainly analyzed young driver's aggressive driving tendency, yet they were only done through pure clustering or classification technique of machine learning. However, since elderly people have different driving habits due to their fragile physical conditions, it is necessary to develop a new method such as enhancing the characteristics of driving data to properly analyze aggressive driving of elderly drivers. In this study, acceleration data collected from a smartphone of a driving vehicle is analyzed by a newly proposed ECA(Enhanced Clustering method for Acceleration data) technique, coupled with a conventional clustering technique (K-means Clustering, Expectation-maximization algorithm). ECA selects high-intensity data among the data of the cluster group detected through K-means and EM in all of the subjects' data and models the characteristic data through the scaled value. Using this method, the aggressive driving data of all youth and elderly experiment participants were collected, unlike the pure clustering method. We further found that the K-means clustering has higher detection efficiency than EM method. Also, the results of K-means clustering demonstrate that a young driver has a driving strength 1.29 times higher than that of an elderly driver. In conclusion, the proposed method of our research is able to detect aggressive driving maneuvers from data of the elderly having low operating intensity. The proposed method is able to construct a customized safe driving system for the elderly driver. In the future, it will be possible to detect abnormal driving conditions and to use the collected data for early warning to drivers.

Objectives: The purpose of this study was to identify the related factors of dental caries and periodontal disease in adolescents from Korean multicultural families, thereby helping to reduce the prevalence rate of oral disease. Methods: The subjects were 710 multicultural adolescents recruited using a web-based survey, National 2015 Korean Youth Risk Behavior, from the Korean Center for Disease Control. A multicultural family was defined in this study as one having an immigrant mother or father. Oral symptoms included dental caries and periodontal disease. Toothache was defined as a symptom of dental caries. Tender or bleeding gums were defined as symptom of periodontal disease. For statistical analysis, Statistical Package for Social Sciences (SPSS) Version 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to determine the factors associated with general characteristics, health behavior, and oral health behavior. Finally, to investigate the associations among oral disease symptoms, logistic regression analysis was performed. Results: Toothache was significantly higher in female 1.52 (95% CI; 1.45-1.60), high school 1.23 (95% CI; 1.18-1.28), women school 1.10 (95% CI; 1.05-1.16), individuals with poor economic status 1.45 (95% CI; 1.30-1.52), and participants who consumed alcohol 1.32 (95% CI; 1.27-1.37). Toothache related to perceived health status was significantly lower in the healthy group 0.69 (95% CI; 0.64-0.75), and was higher in usual stress group 1.65 (95% CI; 1.57-1.74). Gum bleeding was significantly higher in female 1.32 (95% CI; 1.27-1.37), high school 1.15 (95% CI; 1.10-1.19), and individuals with poor economic status 1.38 (95% CI; 1.27-1.50). Gum bleeding related to perceived health status was significantly lower in the healthy group 0.68 (95% CI; 0.63-0.74), and was higher in usual stress group 1.54 (95% CI; 1.46-1.62). Conclusions: Taking into account of social and economic levels, and dietary habits in the multicultural families adolescents, further education and support will be needed for oral disease prevention and early treatment.

This study sought to identify developmental trajectories of bullying victimization from late elementary school through early high school, and to examine internalizing and externalizing problem outcomes associated with the trajectory group membership. Data from Seoul Panel Study of Children were collected annually over a 7-year period from 5th grade of elementary school through 2nd grade of high school (2005~2011). Latent class growth analysis yield three trajectory classes corresponding to stable low (81.2%), stable high (3.5%), and declining bullying victimization (15.6%). Findings from analysis of covariance indicated that students in both stable high and declining trajectory groups reported significantly higher means in internalizing behavior (withdrawal, depression/anxiety, and suicide ideation), compared to those in the stable low group. For externalizing behavior such as aggression and juvenile status offense, students in the stable high group showed higher means, compared to those in the stable low and declining trajectory groups. Developmental pattern of bullying victimization over multiple development stages and associated internalizing and externalizing outcomes are discussed as are the implications for the bullying prevention.

Objectives : Parental behavior is related to personality development and ego resilience in the childhood. The objective of this study was to identify the influence of parental behavior on ego resilience in Korean middle school student. Methods : Subjects were selected based on stratified multi-stage cluster sampling in Korea youth panel study 2013(Boy : N=1,075, Girl : N=1,033). We used Parental behavior inventory(PBI) to estimate parental behavior and the Ego resilience scale to estimate ego resilience. The data were statistically analyzed using a Pearson correlation analysis and regression analysis with the statistical package for the social sciences(SPSS). We considered differences to be significant when p<0.05. Results : A regression analysis showed that rational explanation, affection, Interest and inconsistency of the parental behavior domains influence ego resilience. Also rational explanation, affection and Interest of the parental behavior domains showed a significant positive correlation with ego resilience(r=0.24, r=0.31, r=0.22, p<0.01). In contrast to early childhood studies, inconsistency showed no significant correlation. Conclusions : Adolescents who had taken more rational explanation, interest and affection from their parents were more likely to have higher ego resilience. However, inconsistency of parental behavior showed no correlation with ego resilience of adolescents, which means that they are affected by several other factors than parental behavior. This study would be a basic research that could be a help to psychosocial approach in pediatric psychiatry.

The purpose of this study was to prepare basic data to set the support direction for low-income households in a socioeconomic crisis situation. The study examined the effect of socioeconomic deprivation experience on the longitudinal changes in family conflict and family relationship satisfaction of low-income households. Using five-year data from the 10th to 14th sessions of the Korean Welfare Panel, we examined the longitudinal changes in family conflict and family relationship satisfaction, and the effect of socioeconomic deprivation experience from the reponses of 803 low-income households. We found that the family conflict of low-income households decreased to a weak level with the change of time, and the rate of change in family relationship satisfaction was not meaningful. In the case of families who experienced early socioeconomic deprivation, their initial value of family conflict was higher than that of inexperienced households, and the rate of change was not significant. The results of this study show that when low-income households experience socioeconomic deprivation, they feel psychological pressure and an increase in family anxiety, resulting in high family conflict and low family relationship satisfaction. On the basis of the study results, we recommend extending economic and social assistance to low-income households in the current socioeconomic crisis. The state is also encouraged to help families manage conflicts on their own and resolve problems.

Russian anarchist thinker P. A. Kropotkin had a significant impact on the school of thought, the literary field and the anarchist movement in East Asia in the early 20th century. This paper examines the history of the translation of Kropotkin in terms of the routes and paths of translation in colonial Korea in comparison with those in Japan and China. It is a known fact that the acceptance of Kropotkin in colonial Korea is owed to pioneering translation works in Japan, but it appears that there have been various transformations and magnetizations in the process of translating the texts into the Korean language. Despite a disturbing censorship, the works of Kropotkin, such as "I appeal to the youth ("Aux Jeunes Gens" in French)", were imported, translated and distributed by various routes throughout the 1920s and there were various versions of translated Korean texts. At this point, it is noteworthy that there are works which were translated from Chinese texts about Kropotkin, such as the works of Yu Seo (柳絮), and it can be said that there is a relationship between Korean translations and Chinese original texts. Since the 1930s, the phenomenon of the appropriation of Kropotkin as a litterateur and critic rather than an anarchist thinker is particularly apparent, and this allows us to understand that Kropotkin became a major pathway to interpret Russian literature in East Asia. In colonial Korea, translations of Kropotkin were generally via Japan and China, but the process of translation also showed the struggle to accept and adapt 'the foreign text' into the Korean language.
