This research aims to examine whether depression has mediating effects in the effects of socioeconomic deprivation, especially of lower variables of socioeconomic deprivation on life satisfaction of the elderly. For this purpose, the 12th year(2017) data of the Korea Welfare Panel Study were used. The mediated effect analysis method of Baron and Kenny(1986) were used, and mediating effect of depression was validated through Sobel Test. The results of this research are as follows. Firstly, the lower variables of socioeconomic deprivation of the elderly -deprivation of housing, deprivation of dietary life, social deprivation, deprivation of employment, and deprivation of healthcare- had partial mediating effects of depression in life satisfaction. It was verified that as the elderly experienced deprivation of housing, deprivation of dietary life, social deprivation, deprivation of employment and deprivation of healthcare, depression increased and life satisfaction was lowered. Therefore, it was suggested that to enhance the living satisfactions of the elderly, policies and services reflecting the personal characteristics of socioeconomic deprivation and depression must be made, and that criteria to identify the multidimensional poverty and deprivation experienced in everyday life must be prepared in addition to poverty focusing on income.

This study aims to investigate the mediating effect of outcome expectation in the relationship between strengths knowledge and career adaptability for nursing students. The participants of this study were 284 nursing students in three Universities in G City, J Province. Data analysis used descriptive statistics, t-test, ANOVA, Pearson correlation analysis. Also mediation analysis was performed according to the Baron and Kenny method and Sobel test.. Career adaptability is positively correlated with strengths knowledge(r=.61, p<.001), outcome expectation(r=.55, p<.001), and strengths knowledge is positively correlated with outcome expectation(r=.41, p<.001). The outcome expectation showed a partial mediating effect between the strengths knowledge and the career adaptability(Z=3.85, p<.001). The positive the strengths knowledge(𝛽=.44, p<.001), the higher the outcome expectation(𝛽=.33, p<.001), the higher the career adaptability level, and the explanatory power to explain career adaptability was 50%. Therefore, in order to improve the career adaptability of nursing students, it suggests that it is necessary not only to recognize strengths with positive thinking about individuals, but also to improve attitudes to form desirable outcome expectations at the same time.

This paper presents a novel algorithm for nighttime detection of the lane markers painted on a road at night. First of all, the proposed algorithm uses neighborhood average filtering, 8-directional Sobel operator and thresholding segmentation based on OTSU's to handle raw lane images taken from a digital CCD camera. Secondly, combining intensity map and gradient map, we analyze the distribution features of pixels on boundaries of lanes in the nighttime and construct 4 feature sets for these points, which are helpful to supply with sufficient data related to lane boundaries to detect lane markers much more robustly. Then, the searching method in multiple directions- horizontal, vertical and diagonal directions, is conducted to eliminate the noise points on lane boundaries. Adapted Hough transformation is utilized to obtain the feature parameters related to the lane edge. The proposed algorithm can not only significantly improve detection performance for the lane marker, but it requires less computational power. Finally, the algorithm is proved to be reliable and robust in lane detection in a nighttime scenario.

The purpose of this study was to examine the mediating effect of the adult attachment in the relationship between the family of origin functioning and fear of intimacy. Data were collected through a questionnaire from 557 university students in the Jeollabuk-do of South Korea. The collected data were analyzed by basic descriptive statistics, Pearson's correlations and multiple regression analysis. Baron and Kenny's method was used and examined, and the Sobel test was performed to determine the mediating model's significance. It was adapted to SPSS ver. 18.0 for Windows. The major findings were as follows: first, the functioning of family-of-origin was negatively related to the fear of intimacy. In addition, younger students and students with less past dating experience were more likely to fear of intimacy. Second, fear of intimacy was influenced by the family-of-origin through the intermediate effect of attachment avoidance and attachment anxiety. Attachment avoidance and attachment anxiety had partial mediating effects on the relationship between family-of-origin functioning and the fear of intimacy. That is, family-of-origin functioning was shown to have not only a direct effect, but also an indirect effect through attachment avoidance and attachment anxiety, on the fear of intimacy. The results of this study suggest that the importance of family-of-origin functioning in order to improve Korean college students' intimacy abilities.
