  • Purpose: The purpose of this study was to analyze the effects of a quit smoking program using the Web and short message service on exhaled carbon monoxide, self-efficacy, and depression according to nicotine dependency level in undergraduate students. Methods: In this study a non-equivalent control group pretest-posttest design was applied. The participants included 90 students (52 in the low nicotine dependency group and 38 in the high nicotine dependency group) who succeeded in quitting smoking. Data were collected on 3 occasions, that is, before the program, immediately after the program, and 3 weeks after the program. Collected data were analyzed using independent t-test, repeated measure ANOVA, and paired t-test with SPSS 20.0. Results: Exhaled carbon monoxide was higher in the high nicotine dependency group than in the low nicotine dependency group. Self-efficacy significantly increased 3 weeks after the program in the low nicotine dependency group and significantly increased immediately after the program in the high nicotine dependency group. Depression significantly decreased 3 weeks after the program in the low nicotine dependency group. Conclusion: Self-efficacy may be enhanced when it is dealt with during an early phase of the quit smoking program for the high nicotine dependency group. Long-term intervention and persistent intervention are needed with regard to depression during a quit smoking program.

  • In most application programs, loops usually comprise most of the computation in a program and the most important source of parallelism. When the data dependency relation is uniformin terms of distance, several compile time parallelization methods were introduced. On the otherhand,when the data dependency relation is non-uniform in distance, the compile time extraction ofparallelism is much complicated. In this paper, a general method the extracting parallelism in nestedloops is presented. This algorithm can be applicable where the dependency relation is both uniform andnon-uniform in distance. According to execution repeatedly the statements in nested loops, thealgorithm which effectively removes these kind of data dependencies is developed in order to presentthe total parallelization of nested loops.

  • Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

  • The purpose of the present study was to test the impact of depression on mobile phone dependency among elementary school students, to test the mediating effect of self-esteem between depression and mobile phone dependency, and to draw out theoretical and practical implications in terms of preventing or reducing mobile phone dependency. Based on previous studies, a longitudinal research model between the aforementioned three variables has been identified. The present study analyzed the 4th, 5th, and 6th wave data from Korea Children and Youth Panel Study 2010 (KCYPS 2010). The major results were as follows. First, depression could have a significant negative effect on self-esteem. Second, self-esteem could have a significant negative effect on mobile phone dependency. Third, the influence of depression on mobile phone dependency was not significant. Fourth, gender could be a significant moderating variable between depression and self-esteem. Finally, a number of implications of these findings were also discussed.

  • Business processes are often of long duration, and include internal worker's decision making, which makes business processes to be exposed to many exceptional situations. These properties of business processes makes it difficult to design processes to support uncertainties from internal or external environments. The behavioral properties of business processes mainly depends on the data aspects of business processes. To formalize the data aspect of process modeling, this paper proposes a graph-based model, called Data Dependency Graph (DDG), constructed from dependency relationships specified between business data. The paper also defines a mechanism of describing a set of mapping rules that generates a process model semantically equivalent to a DDG, which is accomplished by allocating data dependencies to component activities.

  • Purpose: The purpose of this study was to investigate the relationship of depression and smartphone dependency with female college students' career decision-making self efficacy. Methods: This was a descriptive study. The survey participants were 497 female college students in M City and S City. Data were collected from November 16 to December 4, 2015 using self-report questionnaires including BDI (Beck Depression Inventory), Smartphone Dependency Scale, and CDMSES-SF (Career Decision-Making Self Efficacy Scale-Short Form). Data were analyzed through descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression. Results: Career decision-making self efficacy showed significant differences according to religion. Smartphone dependency was found to have a statistically significant negative correlation with career decision-making self efficacy and a positive correlation with depression. Depression was found to have a statistically significant negative correlation with career decision-making self efficacy. Stepwise multiple regression analysis revealed that the predictors of career decision-making self efficacy were depression (7.1%), religion (1.8%), and smartphone dependency (1.3%), accounting for a total of 10.6% of the variance. Conclusion: This study suggests that interventions to promote female college students' career decision-making self efficacy should consider their depression, religion, and smartphone dependency.

  • This study examined the influence of self- efficacy for smoking cessation, depression, social support and nicotine dependency in the college male smoker. This survey design was adopted for 149 male college students in Gyeongbuk. Data were gathered from September 7 to 18, 2016. Data was analyzed for descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regression. There was a significant positive correlation between depression and nicotine dependency. There was a significant negative correlation between self-efficacy for smoking cessation and nicotine dependency and between social support and nicotine dependency. The significant factors influencing nicotine dependency were self-efficacy for smoking cessation and depression. This model explained 34% of variance in nicotine dependency. The results suggest that an intervention program is needed to reduce the depression and to increase the ability of self-efficacy for smoking cessation in the college male smoker.

  • Purpose: This study aimed to identify the level of knowledge on preventing cardiovascular disease (CVD) and nicotine dependency among smoking male college students, and to examine the predicting factors of nicotine dependency. Methods: This study was conducted as cross-sectional descriptive research using structured questionnaires. Data were collected from 411 smoking male college students ($22.5{\pm}2.59$ yr) at two universities located in two cities in Korea from September 2012 to April 2013. Logistic regression analysis was performed to estimate age-adjusted odds ratios of nicotine dependency. Results: The mean value of nicotine dependency was $4.2{\pm}1.96$ and the percentage of participants who had strong nicotine dependency (${\geq}7$) was 10.7%. Logistic regression analysis showed that, when adjustment was made for age, nicotine dependency was predicted by the frequency of alcohol drinking (${\geq}3$ times/week), knowledge on CVD prevention, the age starting drinking, and the total length of smoking. Conclusion: Nicotine dependency was strongly related to the frequency of drinking alcohol and lower knowledge on CVD prevention. Therefore, male college students who have a dependent smoking habit and drink alcohol frequently need to take more interest in health through educational counseling to modify their lifestyle behaviors and to have preventive knowledge related to CVD.

  • Objective: This study aimed to examine the moderating effect of elementary school students' perception of open communication with their parents in relationship to smartphone dependency and school adjustment. Methods: Participants included 300 fifth and sixth graders attending P and A elementary schools in Gyeonggi Province. Descriptive analysis, correlation analysis, and hierarchical regression analysis were performed to analyze data. The level of significance was set at p < .05 for all analyses. Results: The results of the present study are as follows: First, male students showed higher levels of smartphone dependency than female students, and students' smartphone dependency increased according to age. The students' smartphone dependency was negatively associated with their school adjustment and their perception of open communication with their parents. Second, the students' perception of open communication with their fathers was found to moderate the relationship between smartphone dependency and school adjustment. Conclusion/Implications: These findings indicate that open communication between parents and their elementary school-aged children can buffer the adverse effects of smartphone dependency on school adjustment. This study provides implications for parent education and counseling to improve parent-child communication and subsequently build strong, positive family relationships.
