This study examined 316 soldiers in the South Korean Army and the mediation effects of social support on bullying and frustration. Bullying, social support, and frustration showed average scores of 2.23, 3.60, and 2.75 points, respectively. There was a positive correlation between bullying, social support, and frustration. All of the subordinate variables of bullying showed significant impacts on frustration (p<.05), with psychological harassment showing the greatest impact (${\beta}=.340$), followed by bullying in interpersonal relationships (${\beta}=.149$) and bullying at work (${\beta}=.130$). In all the interaction items of the subordinate variable bullying ${\times}$ social support, bullying had a significant impact on frustration at p<.01, while the highest impact was shown in the interaction item of bullying ${\times}$ member support (${\beta}=.456$). The results imply that intangible combat power and solidarity among soldiers can be guaranteed only when superiors and peers provide full support for soldiers who are victims of bullying.

The aim of this study was to identify the influences of sleep quality, depression and fatigue on job stress of geriatric hospital workers. The subjects were 175 workers from 6 geriatric hospitals. Data were collected on March, 2015 using a structured questionnaire. The data were analyzed by using SPSS/WIN 21.0 program. The job stress was negatively correlated with sleep quality(r=-.364, p<.001), positively correlated with depression(r=.376, p<.001) and fatigue(r=.646, p<.001). The multiple regression analysis revealed that the most powerful predictor of job stress was fatigue(${\beta}=.581$, p<.001). These results indicate that fatigue affect job stress of the geriatric hospital workers. Therefore, it is necessary to prepare tailored fatigue management program and working conditions that can reduce job stress.

The purpose of this study was to develop a communication simulation and evaluate its applicability of curriculum of community health nursing for nursing students. This study used one- group pretest-posttest design and participants were 35 junior nursing students. Data was collected through self-reported questionnaires of communicative competence and satisfaction and analyzed using paired-t test and descriptive statistics. There was no change of overall mean score of communicative competence, though the simulation program related to communication of community health nurses was developed and the score of satisfaction after the simulation was 4.4 out of 5. In the categories of communicative competence, the score of role competence was increased after simulation(p<.001) but interpretive competence was decreased(p=.029). And others were not significant changes. As these results, the developed simulation program was applicable to community health nursing course, but further consideration is needed about strategies of simulation to increase communicative competence.

The aim of this study was to examine the effect of self-esteem, life satisfaction and quality of life of older people's in an elderly school program. A cross-sectional descriptive study was conducted with a survey of 269 older people in 3 elderly schools at G city from November 29, 2013 to 18. The data was analyzed using a t-test, ANOVA, Pearson's correlation coefficients and multiple regression using the SPSS WIN 20.0 program. As a research finding, an analysis of the quality of life between of the self-esteem (r=-.338, p<.001) and life satisfaction (r=-.507, p<.001) revealed significant correlations. The life satisfaction was the significant factor influencing the quality of life (${\beta}$=-.512, p< .001) and this variable explained 25.1% of the quality of life. The findings of this study should be integrated into elderly health and care services in the community and older people in elderly school programs to improve the quality of life through the systematic developments of intervention programs for health care.

In this paper, we propose a method for multi-touch tracking using MRF-based particle filters and gesture likelihood estimation Each touch (of one finger) is considered to be one object. One of frequently occurring issues is the hijacking problem which means that an object tracker can be hijacked by neighboring object. If a predicted particle is close to an adjacent object then the particle's weight should be lowered by analysing the influence of neighboring objects for avoiding hijacking problem. We define a penalty function to lower the weights of those particles. MRF is a graph representation where a node is the location of a target object and an edge describes the adjacent relation of target object. It is easy to utilize MRF as data structure of adjacent objects. Moreover, since MRF graph representation is helpful to analyze multi-touch gestures, we describe how to define gesture likelihoods based on MRF. The experimental results show that the proposed method can avoid the occurrence of hijacking problems and is able to estimate gesture likelihoods with high accuracy.

Recently, researches to improve a quality and a color of a display are being actively studied because of the prosperous growth of the flat panel displays such as LCD, PDP and OLED. Automatically adjusting color temperatures based on user preferences is the one of the researches to provide the optimum display color. In this paper, along with defining the problems of prior methods, the user preferences against the priori defined ranges proposed by the MPEG-7 color temperature descriptor are inspected. Based on the analysis of user preferences, an optimal color temperature conversion curve is proposed. As a result of an analysis by ANOVA, tendencies of the user preferences against each range are proven to be similar to the prior research results. The repetition of the color temperature conversion against an image is not statistically significant.

The social-democratic ideas which define the modern national Swedish idea have had an important influence on Swedish modern design during this century. Swedish designers found humanistic and democratic values in the traditional design style and they tried to create a modem style that was based on handcraft traditions as well as modern industrial aesthetics. Issues raised by Swedish designers of that time induded how Sweden was achieving a national identity through design and how design retlected changes within society. The purpose of this study is to investigate the social reformation policy of the Swedish government during the 1930-1970 period and its influence on Swedish modern design. This paper, it is hoped, will provide an opportunity to place contemporary Swedish design in a social and aesthetic context.

This study was aimed to identify the effects of social intelligence and burnout on the turnover intention in nurses as a descriptive study. The data were collected between August 3 and September 1, 2015. A total of 188 nurses working at university medical centers and general hospitals located at J city and D city were participated. The collected data were analyzed using frequency, mean and standard deviation, t-test, ANOVAs, Pearson's correlation coefficients and hierarchical regression analysis. In turnover intention, there were significant differences in education, age, job preference of nurse, work period and position. Burnout showed significant effect in social intelligence and turnover intention. Social intlligence did not have control effect between turnover intention and job burnout. This findings suggested that to prevent the nurse's turnover intention, the education for social information, social skill and social awareness has to be programmed for the development of social intelligence.
