Purpose: This study aims to prevent Smartphone addiction and provide a basic material for intervention strategy by inquiring into the correlation between interpersonal relations competency and Smartphone addiction. Methods: This study carried out a questionnaire survey oriented to 323 people who agreed to participate in this research. For the final analysis, this study selected 298 sheets of questionnaires excluding 25 sheets with insufficient response qualities. Results: According to the results of regression analysis, significant correlation between interpersonal relations competency and Smartphone addiction level was not observed. However, according to the results of correlation analysis, the subordinate factor of Smartphone addiction "directionality of virtual world" showed a significant negative correlation with "opinion expression regarding rights or refusal" of interpersonal relations competency (p<0.05), while "withdrawal," the subordinate factor of interpersonal relations competency and Smartphone addiction displayed a negative correlation with Smartphone addiction (p<0.05). Conclusion : However, the mean of the 3DP group was within the clinical tolerance suggested by the previous researchers.

This study conducts numerical analyses of a thin-walled composite cylinder under axial compression and internal pressure of 10 kPa. Numerical vibration correlation technique and nonlinear postbuckling analyses are conducted using the nonlinear finite element analysis program, ABAQUS. The single perturbation load approach and measured imperfection data are used to represent the geometric initial imperfection of thin-walled composite cylinder. The buckling knockdown factors are derived using present initial imperfection and analysis methods under axial compression without and with the internal pressure. Furthermore, the buckling knockdown factors are compared with the buckling test and computation time are calculated. In this study, derived buckling knockdown factors in present study have difference within 10% as compared with the buckling test. It is shown that nonlinear postbuckling analysis can derive relatively accurate buckling knockdown factor of present thin-walled cylinders, however, numerical vibration correlation technique derives reasonable buckling knockdown factors compared with buckling test. Therefore, this study shows that numerical vibration correlation technique can also be considered as an effective numerical method with 21~91% reduced computation time than nonlinear postbuckling analysis for the derivation of buckling knockdown factors of present composite cylinders.

Grandparent-grandchildren family adolescents(GGFAs) need to be well discussed because they tend to be more influenced by the negative surroundings than ordinary family adolescents. Over the past few years, several studies have been made on the correlation between the risk factor, the protective factor and the school resilience of GGFAs, but these studies have the limit to explain the only correlation between the one factor and the school resilience. So the purpose of this study was to examine not only the direct effect between the risk factor and the protective factor, but also the parametric path and effect that the one factor has influence on the correlation between the another factor and the school resilience of GGFAs. We investigated the 328 GGFAs in Korea, and the analytic method used was the Structural Equation Modeling(SEM). The followings are the results of this paper. It was found that the model adaptability had a considerable validity by inspecting the SEM, which showed not only the direct effect between the risk factor, protective factor and the school resilience of GGFAs, but also the mediation effect by the protective factor. The risk factors - the indifference of teacher, the negative attachment relationship, melancholy, uneasiness etc - had a negative influence on the school resilience of GGFAs. The protective factors - the supporss etteacher, self-esteem etc - had a positive influence on the school resilience of GGFAs. The protective factors were found to reduce the negative influence on the school resilience of GGFAs.

Objectives : The purpose of this study is to find out the correlation between the Vocal indicators and the 'Buzhongyiqi-Tang questionnaire' and the 'Chalder fatigue scale.' Methods : This study examined the mean value of each factor in the 'Buzhongyiqi-Tang Questionnaire,' 'Chalder fatigue scale' and the different voice indicators conducted on 81 healthy adult participants in relation to the results of the /a/ /e/ /i/ /o/ /u/ pronunciation test. Results : There was significant correlation between the pronunciation of /a/ /e/ /i/ /o/ /u/ vowels' F0 indexes and 'the Deficiency symptoms of Buzhongyiqi-Tang'. The results of the regression analysis showed the following significant findings for each pronouncing vowels: /i/ as a factor for 'the Deficiency symptoms of Buzhongyiqi-Tang'.; /a/ for 'the Consumptive fever of Buzhongyiqi-Tang'.; /i/ for 'the Vocal inflammation of Buzhongyiqi-Tang.; and /e/ as a factor of 'the Chadler physical fatigue'. Conclusions : The study showed a negative correlation between the Fundamental Frequency and the mean value of the questionnaire, which could be understood as higher the fatigue level, increased level of vocal vibration and higher pitch tone compared to the less fatigued group. We expect future studies to conduct research on methods to diagnose other illnesses using the vocal indicators based on the correlation between the vocal index and illnesses prescribed under traditional oriental medicine.

Objective: The purpose of this study was to analyze correlation effect size between Basic Psychological Needs (BPN) and factors affecting BPN. Methods: This research was reviewed and synthesized systematically by meta-analyse. Fifty-eight published studies between 2008 and 2016 were sampled and the effect sizes were acquired. Results: The major findings were as follows. In general, medium correlation effect sizes were found. Competency among sub-factors of BPN showed highest effects. Parental factor was more related to BPN than school and individual factors. Parenting behavior and family psychological backgrounds were the most crucial factors in the parental factors. School adjustment was the most critical factor in the school factors. In school grade, the elementary school was more related to BPN than junior high school and high school. Conclusion: Based on these results, we suggest a number of components for parent-education programs, and information for future research.

This paper presents the correlation on the contamination degree and weather conditions using the multiple regression of the statistic method. The cotamination is a significant factor in the insulation system. The major factor is natural contamination, and the most is the salt. The salt contamination is occured by the weather conditions. The weather contaminations are wind, precipitation, temperature, relative humidity, etc. The effects of those are different, and the correlation is showed numerically by using the multiple regression method of the statistic method. With this, the estimation of the equivalent salt deposit density(ESDD) becomes possible by the changes of the weather conditions.

In this article, a reduction method for nominal variables is presented and its use illustrated. Factor analysis model (FAM) generally enables us to reduce variables having interval or ratio scale based on their correlation coefficients. We developed an extensive method that makes FAM applicative to the case of nominal variables which does not give correlation coefficients, but only the degree of association. Cramer's V coefficient is a well-established measure that provides the strength of association for nominal variables with a range of [0,1]. When Cramer's V coefficient can logically substitute for correlation coefficient, FAM would be extensively used for reduction of nominal variables.

To analyze the skeletal characteristics of the open bite, the faces of normal occlusion and open bite were measured using a cephalogram. The factors which were greatly different from normal occlusion were selected. The effects of these factors on the incisal overbite and correlation on these factors were studied. The following results were obtained: 1. The 13 factors which comprised the characteristics of the open bite were obtained. (Table 5) 2. The cause and amount of the open bite were dependent on the skeletal angulation than skeletal length. 3. For determining the incisal overbite, most highly correlated single factor was the interincisal angle. 4. The correlation on the selected 13 factors which comprised the characteristics of the open bite was obtained. (Table 6) 5. The open bite was due to combination of various factors than due to single factor. (Table 3,4).
