This study explores how the main variables of youth going through a transition period (parents' nurturing behavior, the youth's self-esteem and ego resilience, the peer group relationships) affect the youth's school adjustment. It also analyzes the effects of theses variables on the youth's dependence on cell phones, which are considered a necessity in modern society. This research is verified by using a structure model verification method based on data from the Korean Children Youth Panel Study. According to the research, first, 1st-year students in middle school show better adjustment to their school life and less dependence on cell phones when they have a stronger sense of self-esteem and ego resilience; further, it is revealed that cell phone dependence has an indirect influence on the school life of these children. Second, they tend to show better adjustment to their school life and less dependence on cell phones when their parents' nurturing behaviors are more positive. Third, these children tend to depend more on cell phones when they have a positive peer group relationship, Moreover, cell phone dependence has an indirect influence on their school life. When considering the impact of cell phone to youth in modern society, need to prepare proper training program for correct uses and preventing from addiction.

We propose a simple identification scheme for the causes of the violations of uncovered interest parity. Our method uses the serial dependence patterns of excess returns as a criterion for judging performance of economic models. We show that a mean reverting component in excess returns, representing a violation of uncovered interest parity, mainly contributes to generating different serial dependence patterns of excess returns: rational expectations risk premium models tend to generate negative serial dependence of excess returns, while expectational errors models tend to generate positive serial dependence.

The purpose of this study was to represent hypotheses of the interrelationship of the level of cooperation, conflict, and performance and to report the findings testing the hypotheses in car channels. This study provides some general guidance toward better cooperation, conflict, and performance management. The results indicate that noncoercive bases of power and dependence hale a positive effect on cooperation, while the proposed inverse relationship between coercive bases of power and cooperation is not statistically significant. Coercive bases of power have a positive effect on conflict, while conflict is not statistically significant for noncoercive bases of power, dependence, and cooperation. Finally, cooperation has a positive effect on dealer performance, but conflict has a negative effect on dealer performance.

It is widely confirmed that online retailers can obtain crucial resources and greater growth potential by depending on the external web portal sites as it is explained in resource dependence theory. Nevertheless, recent studies show that the effect of dependence may not always be beneficial for firms and stress the importance of finding relevant contingent factors. In this study, we identify and suggest that firms' age and niche width strategy, whether generalist or specialist, are contributing factors on moderating the positive relationship between resource dependence and firm growth. To test our hypotheses based on the theory, we have collected monthly web traffic data of online retailers and portals from March 2000 and July 2008. The empirical results lend support to our theory of the firm age having a negative interaction effect on web traffic dependence. Moreover, results verified that positive effect of depending on the portals may become greater if the online retailer is a specialist in terms of niche width.

This paper deals with the stochastic comparisons of order statistics from independent but nonidentically distributed (i.n.i.d) variates. And we consider order statistics under positive dependence, negative dependence, and exchangeability.

This study has investigated the mediating effects of dependence, goal incongruence, and conflict in processing of environmental dynamism effects on the dissolution intention in the discount store industry. As the result of hypotheses test using data collected from 180 supplier samples, environmental dynamism has the positive effects on dependence, goal incongruence, and conflict. Goal incongruence has the positive effect on conflict. Goal incongruence and conflict has the positive effects on dissolution intention. But, dependence didn't decrease dissolution intention significantly. Finally, the authors discussed the theoretical contributions, managerial implications, and limitations of this study and presented the future research directions.

The purpose of this study is to investigate the structural relationship among brand dependence, brand attitude, brand satisfaction and repurchase intention of online golf goods consumers. To achieve the purpose of this study, a survey was conducted on consumers who had experience in purchasing golf goods online by visiting golf driving ranges in Seoul and Kyeonggi area. A total of 200 people were surveyed and 197 data were used for the final data processing. SPSS 23 and AMOS 23 were used for data processing. We obtained the following results. First, brand dependence had a positive effect on brand attitude, but it did not have a significant effect on repurchase intention.Second, brand attitude had a positive effect on brand satisfaction and repurchase intention; third, brand satisfaction had a positive effect on repurchase intentionFirst, face has been shown to have a significant impact on symbolic consumption propensity. Second, symbolic consumption tendencies have a significant impact on product satisfaction and intention to purchase new products. Third, product satisfaction has been shown to have a negative impact on the intention of purchasing new products.

Lehmann [13] introduced the concept of positive(negative) dependence together with some other dependence concepts. Since then, a great numerous multivariate inequalities have been obtained. For a references of available results, see Karlin and Rinott [12], Ebrahimi and Ghosh [8] and Sampson [14]. Whereas a number of dependence notions exist for multivariate processes (see Friday [10]), recently, Ebrahimi [7] introduced some new dependence concepts of the hitting times of stochastic processes.

The asymptotic dependence between the central quasi-ranges and empirical quantiles was studied. The asymptotic dependence are obtained when the sample size is a positive integer valued random variable (r. v.). The dependence conditions and limit forms are obtained under generl conditions such as : the interrelation of the basic variables (the original random sample) and the random sample size is not restricted. In additition the normalizing constants do not depend on the random size.

Objectives: The purpose of this study is to investigate the relationship of nicotine dependence and mental health. Methods: The subjects of this study were 153 male smokers in their 20s, 30s, 40s and 50s who visited Wonmi Public Health Center. They were evaluated with Fagerstorm's test for nicotine dependence (FTND) and Symptom Checklist-90-Revision (SCL-90-R). Using the FTND score, the participants were divided into three groups; mild nicotine dependent group, moderate group and severe group. Results: In the SCL-90-R score, there were statistically significant differences in the characteristics of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Global Severity Index (GSI) and Positive Symptom Test (PST) among the three groups. Comparing the values of FTND and the amounts of Daily Smoking to the values of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression and GSI in this study resulted in positive correlations, thereby demonstrating a statistical significance. Conclusions: The above results suggest that there are significant relations between nicotine dependence and the level of mental health. These results can be used for planning the smoking cessation program and mental health promoting program based on Korean traditional medicine.
