This paper presents the results of a numerical investigation on load carrying capacity of geogrid-encased stone columns to use as load carrying column(s) supporting a foundation load. A validated 3D stress-pore pressure coupled model that can effectively show rapid drainage capability of stone columns and encasement effect of geogrid was adopted and a parametric study was carried out on a number of influencing factors. It is shown that the geogrid encased stone columns can be effectively used as foundation load supporting columns in soft ground. The results of numerical investigation were presented so that the relationship between the load carrying capacity of geogrid-encased stone columns and the influencing factors can be identified. Practical implications of the findings are also discussed.

This study explored how peers influence on adolescents' game over-indulgence. More specifically, it was examined the effects of emotional support, subjective norm of game use, peer stress, and friends' attitude toward gaming on game over-indulgence. Results showed that the higher level of subjective norm of game use and peer stress one received the higher level of game over-indulgence one reported. However, lower emotional support caused higher game over-indulgence. Meanwhile, friends' attitude toward gaming was not significantly related to game over-indulgence. The meaning and the importance of peer in terms of game over-indulgence and limitations of the study were discussed.

Objectives: Bipolar disorder is characterized by repetitive relapses that result in psychosocial dysfunctions. The functioning of bipolar disorder patients is related to the severity of symptoms, quality of sleep, drug compliance, and social support. The purpose of this study was to investigate the association between sociodemographic and clinical factors and functional status in bipolar disorder patients. Methods: A total of 52 bipolar disorder patients participated in the study. The following scales were utilized: Korean version of personal and social performance scale (K-PSP), Korean version of Hamilton rating scale for depression (K-HDRS), Korean version of young mania rating scale (K-YMRS), Korean version of pittsburgh sleep quality index (PSQI-K), Korean version of drug attitude inventory (K-DAI), mood disorders insight scale (MDIS), and multidimensional scale of perceived social support (MSPSS). Results: The K-PSP score showed a negative relationship with K-HDRS score (r = -0.387, p = 0.005), but not with K-YMRS score (r = -0.205, p = 0.145). The K-PSP score showed a negative relationship with global PSQI-K score (r = -0.378, p = 0.005) and overall sleep quality (r = -0.353, p = 0.010). The K-PSP scores were positively associated with the KDAI score (r = 0.409, p = 0.003) and MSPSS score (r = 0.334, p = 0.015). The predictive factors for K-PSP were overall sleep quality and social support from family. Conclusion: Our study showed that depressive symptoms were related to overall function in bipolar disorder. Also, our study suggested that improving sleep quality is important in maintaining functional status. Appropriate social support and positive perception toward the drug may lead to the higher level of functioning. This study is meaningful in that the functional status of bipolar disorder patients is analyzed in a multivariate manner in relation to various variables in psychosocial aspects.

The purpose of this study was to investigate the influence of SNS addiction tendency, pathological narcissism, social support, and stress among university students. Data were collected via questionnaires from 385 students and were analyzed by descriptive statistics, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficients, and Stepwise multiple regression analysis using SPSS/WIN 19.0 program. The levels of SNS addiction tendency depended on gender, SNS usage time, SNS over-usage, health problem, and household economic status. SNS addiction tendency was significantly correlated with pathological narcissism, social support, and stress. Influential factors that affect SNS addiction tendency were pathological narcissism, SNS usage time, SNS over-usage, gender, social support, and academic performance, which explained about 39.4% of the variance. The results of this study indicate that nursing interventions are necessary to improve SNS addiction tendency, and also suggesting that such variables should be carefully considered in intervention programs for university students.

Association rule of data mining techniques is the method to quantify the relevance between a set of items in a big database, andhas been applied in various fields like manufacturing industry, shopping mall, healthcare, insurance, and education. Philosophers of science have proposed interestingness measures for various kinds of patterns, analyzed their theoretical properties, evaluated them empirically, and suggested strategies to select appropriate measures for particular domains and requirements. Such interestingness measures are divided into objective, subjective, and semantic measures. Objective measures are based on data used in the discovery process and are typically motivated by statistical considerations. Subjective measures take into account not only the data but also the knowledge and interests of users who examine the pattern, while semantic measures additionally take into account utility and actionability. In a very different context, researchers have devoted a lot of attention to measures of confirmation or evidential support. The focus in this paper was on asymmetric confirmation measures, and we compared confirmation measures with basic association thresholds using some simulation data. As the result, we could distinguish the direction of association rule by confirmation measures, and interpret degree of association operationally by them. Futhermore, the result showed that the measure by Rips and that by Kemeny and Oppenheim were better than other confirmation measures.

This study was conducted to investigate the prevalence, severity or impact of symptoms in hemodialysis patients and its relationship with self efficacy and family support to identify factors influencing their symptoms. A cross-sectional design was used and the subjects were 243 patients undergoing hemodialysis at local units. The patients were Dialysis Symptom Index (DSI), a questionnaire about the presence and severity of symptoms. The data were analyzed by descriptive statistics, independent t-test, Pearson coefficient correlation and multiple regression. There were significant differences in the total score of symptoms according to age and duration of hemodialysis. Symptoms score had significant negative correlations with family support (r=-.35, p<.001) and self-efficacy (r=-.16, p=.006). Family support explained 16.0% of the variance in symptoms score. Hemodialysis patients experience many distressing symptoms, which have negative effects on quality of their life. Promoting family support can help to reduce and control distressing symptoms in hemodialysis patients.
