The purpose of this study is to analyze the effects of the frequencies of family leisure activities and family meals and family closeness on the sociality of elementary school children. From October 1 to November 30, 2010, data were collected from 290 elementary school children and their parents residing in Seoul and Incheon. The major findings of this study were as follows. First, there was a significant difference between double-income and single-income families in the frequency of family meals single-income families enjoyed fewer family leisure activities and more family meals than double-income families did. Second, the levels of family closeness were significantly predicted by the frequencies of family leisure activities and family meals, and family meals more significantly predicted the levels of family closeness than did family leisure activities. Finally, the frequencies of family leisure activities and family meals significantly predicted the levels of children's sociality, as did the levels of family closeness. In conclusion, family leisure and family meals are important activities that enhance family closeness and children's sociality.

In this paper, we build a theoretical framework for quantitatively measuring and graphically representing the degrees of closeness centralization among performers assigned to enact a workflow procedure. The degree of closeness centralization of a workflow-performer reflects how near the performer is to the other performers in enacting a corresponding workflow model designed for workflow-supported organizational operations. The proposed framework comprises three procedural phases and four functional transformations, such as discovery, analysis, and quantitation phases, which carry out ICN-to-WsoN, WsoN-to-SocioMatrix, SocioMatrix-to-DistanceMatrix, and DistanceMatrix-to-CCV transformations. We develop a series of algorithmic formalisms for the procedural phases and their transformative functionalities, and verify the proposed framework through an operational example. Finally, we expatiate on the functional expansion of the closeness centralization formulas so as for the theoretical framework to handle a group of workflow procedures (or a workflow package) with organization-wide workflow-performers.

The present study investigated psychological closeness between grandmothers and their grandchildren and functional aspects of grandmothers in the Korean family. 219 grandchildren, fifth and sixth grade children of 5 elementary schools in Seoul completed questionnaires. The results showed that grandmothers in Korea are categorized in an institutional role characterized by status and role performance. Among social role theory, resource theory and system views, the social role theory best explained psychological closeness between grandmothers and grandchildren.

A hot-issued research topic in the workflow intelligence arena is the emerging topic of "workflow-supported organizational social networks." These specialized social networks have been proposed to primarily represent the process-driven work-sharing and work-collaborating relationships among the workflow-performers fulfilling a series of workflow-related operations in a workflow-supported organization. We can discover those organizational social networks, and visualize its analysis results as organizational knowledge. In this paper, we are particularly interested in how to visualize the degrees of closeness centralities among workflow-performers by proposing a graphical representation schema based on the Graph Markup Language, which is named to ccWSSN-GraphML. Additionally, we expatiate on the functional expansion of the closeness centralization formulas so as for the visualization framework to handle a group of workflow procedures (or a workflow package) with organizational workflow-performers.

A multiple criteria model for the facility layout problem considers both of the quantitative, the cost of the work flow, and qualitative, the closeness rating score, aspect. Rosenblatt, Fortenberry & Cox and Urban have developed multiple criteria models that consider both of the quantitative and qualitative aspect. Fortenberry & Cox's multiplicity model penalizes facilities with undesirable closeness rating and high work flows more than those undesirable closeness rating and low work flow between them to contribute to the objective function regardless of the closeness rating between these facilities. In this paper, it is intended to develops a improved multiple-criteria facility layout model considering the function for maintaning the distance between facilities.

This study examined the effects of young children's effortful control, maternal parenting and teacher-child closeness relationship on young children's leadership. The subjects of this study were 266, 4-5 year old children and their mothers and teachers. Young children's effortful control, maternal parenting, teacher-child relationship and leadership were assessed by mother's and teacher's report. The collected data were analyzed by means of Pearson's correlation and pathway analysis. The results were as follows: first, teacher-child closeness relationship was found to affect young children's leadership directly and indirectly through young children's effortful control. Second, maternal parenting was found to affect young children's leadership indirectly through young children's effortful control. Third, young children's effortful control was found to affect leadership directly and to have a mediating effect between maternal parenting and young children's leadership, and between teacher-child closeness relationship and young children's leadership. Additionally teacher-child closeness relationship was found to be the most important variable predicting young children's leadership. These findings suggest that teacher-child closeness relationship could be the most important means by which we could improve both young children's effortful control and leadership.

This paper implements an estimated closeness centrality ranking algorithm in large-scale workflow-supported social networks and performance analyzes of the algorithm. Existing algorithm has a time complexity problem which is increasing performance time by network size. This problem also causes ranking process in large-scale workflow-supported social networks. To solve such problems, this paper conducts comparison analysis on the existing algorithm and estimated results by applying estimated-driven RankCCWSSN(Rank Closeness Centrality Workflow-supported Social Network). The RankCCWSSN algorithm proved its time-efficiency in a procedure about 50% decrease.

From a social network of n nodes connected by l lines, one may produce centrality measures such as closeness, betweenness and so on. In the past, the magnitude of n was around 1,000 or 10,000 at most. Nowadays, some networks have 10,000, 100,000 or even more than that. Thus, the scalability issue needs the attention of researchers. In this short paper, we explore random networks of the size around n = 100,000 by Monte-Carlo method and propose Monte-Carlo algorithms of computing closeness and betweenness centrality measures to study the small world properties of social networks.

Air transport markets are composed of airlines' networks through their base airports. The analysis of an air transport market has been focusing on determining the efficiency or competitiveness of airports or airlines in the market using number of routes, number of passengers, transfer rates, revenues, costs, and other data. However, little work has been done in analyzing the airport network itself. Assuming the air transport markets of Korea, China, and Japan are integrated, this paper aims to analyze the characteristics of the resulting airport network. To that end, the degree of connectivity, the degree of closeness, and the betweenness of centrality are employed. The analysis shows that Incheon International Airport is better than most other airports in terms of the degree of connectivity and that of closeness. Airports in Japan, however, exhibit strong connectivity but weak closeness and betweenness of centrality. Although it has low connectivity, Shenyang Airport has a possibility of becoming an attractive point of the integrated market in the future due to its high degree of closeness.
