Although previous studies on social commerce have provided much insight, more studies in the perspective of social network are needed because social commerce happens within online communities or virtual groups, where buyers connect and interact with each other by sharing information. So, the purpose of this study is to investigate how transactive memory as network characteristic can affect social commerce behavior through social support and relationship quality. We verified the relational effect among social support, relationship quality, and social commerce intention in the Korean market context. Moreover, we found transactive memory capability also played an essential role in the field of social commerce. Specifically, we found consumer's transactive memory capability plays a significant moderating role in the relation between social support and relationship quality.

In this paper, an improved one-against-one support vector machine algorithm is used to classify multiple power quality disturbances. To solve the problem of parameter selection, an improved particle swarm optimization algorithm is proposed to optimize the parameters of the support vector machine. By proposing a new inertia weight expression, the particle swarm optimization algorithm can effectively conduct a global search at the outset and effectively search locally later in a study, which improves the overall classification accuracy. The experimental results show that the improved particle swarm optimization method is more accurate than a grid search algorithm optimization and other improved particle swarm optimizations with regard to its classification of multiple power quality disturbances. Furthermore, the number of support vectors is reduced.

The purpose of this study was to examine the impact of family support and social support on the hopelessness of rural elderly people in an effort to provide some information on the improvement of elderly people's quality of life. The rural elderly people investigated didn't think that they were given lots of support from their families and society, and they didn't feel hopeless a lot, either. The hopelessness of the elderly people was under the negative influence of emotional support and instrumental support among the subfactors of family support, and that was affected in a negative way by affective support among the subfactors of social support. Therefore it could be said that the rural elderly people felt hopeless less when they were provided with more emotional support, more instrumental support and more affective support. Overall, social support had a negative impact on the hopelessness of the rural elderly people. The findings of the study suggest that in order to step up the improvement of rural elderly people's quality of life, a well-functioning model should be developed and applied in collaboration with local community, and the construction of a social support network is required as well.

The purpose of this study was to test the multiple mediating effects between attachment and life quality among university freshmen, regards on positive and negative affect, stress, social support and mental health as mediating factors. 200 freshmen were selected for the questionnaire study in a university in Busan. There were significant correlations among positive and negative affect, stress, social support, mental health and life quality with attachment. The maximum likelihood estimation revealed that attachment had no direct link with life quality. Attachment had indirect effects on life quality, mediated by positive affect and mental health. The results and limitations of this study were also discussed, from the perspective of attachment theory and previous studies.

Recent improvements in the standard of living, national income and medical care, and a decline in the infant death rate which have occurred related to economic growth and modernization, have led to a longer average life-span and a higher ratio of elderly people in the total population, Therefore, not only in the field of nursing science, but also in the field of many other discipline, issues concerning the elderly have been given increasing interest. A great deal of effort has been spent on increasing the quality of life for elderly people. This study was conducted to analyze the correlation between social support and quality of life. The sample consisted of III subjects residing at home and 107 subjects residing in institutions all of whom were over 65 years of age. The data collection period was from October 23, 1990 to January 26, 1991. Social support was measured using the Norbeck social Support Questionnaire developed by Norbeck, translated by Oh, Ka Sil and quality of life was measured using the QOL scale developed by No, You Ja. Data were analyzed using pereentages, t-test, Pearson Correlation Coefficient and ANOVA. The results of this study are as follows : 1. There was a statistically signifivant difference in the level of social support between the two groups (t＝-8.83, p＜.001), The elderly at home reported a much higher level of social support. 2. There was a statistically significant difference in the level of QOL between the two groups (t＝-5.77, p＜.001) . The elderly at home reported a much more positive quality of life. 3. There was a positive correlation between social support and QOL for the elderly at home ard it was statistically significant (r＝.32, p＜.001). 4. There was a postitive collealtion between social support and QOL for the elderly in institutions and it was also statistically significant (r＝.19, p＜.05). 5. The relationship between the general characteristics of the elderly at home and the variables of social support and of QOL were as follows ; 1) according to sex(t＝10.57, p＜.01) and the number of offspring(F＝6.19, p＜.01), there was a statistically significant difference in social support. 2) according to amount of Pocket money, there was a statistically significant difference in QOL(F＝2.98, p＜.05). 6. The relationship between the general characteristics of the elderly in institutions and the two variables were as follows ; 1) according to sex(t＝6.24, p＜.05), the number of offspring(F＝6.16, p＜.001) and religion (F＝2.58, p＜.05), there was a statistically significant difference in social support. 2) according to religion, there was a statistically significant difference in QOL(F＝2.90, p＜.05). In conclusion, it can be said that social support is an important variable related to QOL in the elderly and that social support levels are higher for the elderly residing at home. Therefore, more specific and objective approaches and efforts are needed to effectively use resources to maintain the elderly at home and to enhance social support available to the elderly in institutions and thereby increase QOL regardless of residence.

The automated part quality inspection poses many challenges to the engineers, especially when the part features to be inspected become complicated. A large quantity of part inspection at a faster rate should be relied upon computerized, automated inspection methods, which requires advanced quality control approaches. In this context, this work uses innovative methods in remote part tracking and quality control with the aid of the modern equipment and application of support vector machine (SVM) learning approach to predict the outcome of the quality control process. The classifier equations are built on the data obtained from the experiments and analyzed with different kernel functions. From the analysis, detailed outcome is presented for six different cases. The results indicate the robustness of support vector classification for the experimental data with two output classes.
