We identified a competition network which has never been studied before and investigated the relationship between centrality of participants in singing competition and their winning percentage within the competition network. We collected competition data from 'Immortal Songs: Singing the Legend', which is a Korean television music competition program, and constructed a competition network. We calculated centrality and winning percentage and analyzed their relationship using correlation analysis, regression analysis, and visualization. There are four main findings in this research. First, a competition network is a scale-free network whose degree distribution follows a power law. Second, there is a logarithmic relationship between the count of competition and closeness. Third, winning percentage converges to approximately 60% for players who have participated in more than 20 competitions. Lastly, a strength of opponents affects approximately 23% of winning percentage for players with less than 20 competitions. The academic significance of this study is that we pioneered the definition of the competition network and applied social network analysis method. Another significant contribution of this paper is that we found explicit patterns between the centrality and winning percentage, suggesting ways to improve social relationship in competition network and to increase winning percentage.

The present study investigated the relationship between adult attachment and depression and the moderating effects of social support in secondary school teachers. Survey data was collected from 231 secondary school teachers working at three middle and high schools in the Seoul and Gyung-gi areas. Correlation and hierarchical multiple regression analyses were used to test the relationships among the main variables, namely adult attachment, social support, and depression, and the three moderating effects of social support in the relationship between adult attachment and depression, respectively. The main results were as follows. First, each sub-dimension of adult attachment, namely dependent attachment, anxiety attachment, and close attachment, were significantly correlated with depression levels. All of the variables except senior support and dependent attachment were significantly correlated with depression. Second, social support had a moderating effect in the relationship between anxiety attachment and depression. Colleague and family support had moderating effects in the relationship between dependent attachment and depression though senior support did not.

Mobile phone users have diversified human factors: their channel orientations are different, and the degrees of unwillingness to communicate vary. We examined the effect of human factors on the use of mobile phone, such as the diversity of mobile phone use, the appropriateness of mobile phone, and the aversion to mobile phone as well as the interpersonal communication network through mobile phone. For our sample we surveyed college students and their family members who are older than 400. We found that the more social presence a mobile phone user gets through the mobile phone, and the more familiar to the mobile phone he/she is, (1) the more diversified is the use of mobile phone service, (2) the higher is the level of acceptance of the mobile phone as an interpersonal communication media, and (3) the lower is the level of aversion to the mobile phone. In contrast, those who have some level of aversion to the face-to-face communication, seem to form very limited interpersonal communication network through mobile phone. Their use of mobile phone is also very limited.

The purpose of this study was to examine the relationship among children's perceived parental attachment, parental happiness, and children's autonomy, and to find out in detail the influence of parental attachment and parental happiness on children's autonomy. Frequency analysis and descriptive statistical analysis were performed on data from the 12th year of the Korean Children's Panel (2019), and Pearson's moment correlation coefficient was calculated for correlation analysis between variables. Multiple regression analysis was conducted to examine the influence of parental attachment and parental happiness on children's autonomy. The research results were as follows. First, parental attachment perceived by children, parental happiness, and children's autonomy were all positively correlated. Second, among the sub-variables of parental attachment, maternal trust, paternal trust, and maternal communication were found to have an influence, and only maternal happiness was found to have an effect on parental happiness. This means that parental attachment acts as a more important variable than parental happiness. Therefore, we need constant attention and effort to support children in a more intimate and stable relationship with their parents so that they can gain life satisfaction through active and proactive choices and decisions.

Human communication researchers have suggested that good communication between husbands and wives is a key to a healthy marriage. Although interpersonal communication itself cannot "fix" all problems in one's marriage, the importance of good communication in a marital-relationship cannot be overstated. Regardless of its importance, the communication behavior between husbands and wives as a research topic has been paid little attention by human communication scholars in Korea. Because of the "intimacy" Korean couples who have been influenced with the long tradition of Confucius culture tend to overlook the communicative problems in a marital-relationship. Yet, it is "the belief" of the intimacy that creates much of the communicative problems in a marriage. This study is designed to explore the characteristics and transitional process of the communication behavior between Korean husbands and wives among generations. Married couples in their 20's, 30's, 40's, and 50's were surveyed with five levels of interpersonal communication process-open attitudes, problem-solving, expression, listening, and feedback. The study result reveals each generation's characteristics and transitional process of marital communication behavior from younger couples to older couples as their intimacy and "shared" lived-experience get accumulated.

In fast long-distance networks, TCP's congestion control algorithm has the problem of utilizing bandwidth effectively. Several window-based congestion control protocols for high-speed and large delay networks have been proposed to solve this problem. These protocols deliberate mainly three properties : scalability, TCP-friendliness, and RTT-fairness. These protocols, however, cannot satisfy above three properties at the same time because of the trade-off among them This paper presents a new window-based congestion control algorithm, called EM (Exponential Increase/ Multiplicative Decrease), that simultaneously supports all four properties including fast convergence, which is another important constraint for fast long-distance networks; it can support scalability by increasing congestion window exponentially proportional to the time elapsed since a packet loss; it can support RTT-fairness and TCP-friendliness by considering RTT in its response function; it can support last fair-share convergence by increasing congestion window inversely proportional to the congestion window just before packet loss. We evaluate the performance of EIMD and other algorithms by extensive computer simulations.

Clustering is a data mining method which help discovering interesting data groups in large databases. In traditional data clustering, similarity between objects in the cluster is measured by pairwise similarity of objects. But we devise an advanced measurement called item similarity in this paper, in terms of nature of clustering transaction data and use this measurement to perform clustering. This new algorithm show the similarity by accepting the concept of relationship between different attributes. With this item similarity measurement, we develop an efficient clustering algorithm for target marketing in each group.

The rapidly evolving social platform marketing landscape has led businesses to increasingly rely on social platform influencers for brand and service promotion. Despite growing interest in these influencers, there remains a dearth of empirical research examining the impact of their characteristics on consumer attachment and brand loyalty. This study, therefore, investigates the relationships between social platform influencer characteristics, consumer attachment, and brand loyalty. An online survey targeting Chinese consumers was conducted, and a total of 360 responses were analyzed using SPSS and AMOS software. The findings reveal that among the various social platform influencer characteristics, reliability, professionalism, and intimacy significantly influence consumer attachment. Furthermore, it was confirmed that higher attachment to a social platform influencer leads to increased brand loyalty.
