The purpose of this study was to examine the relationship between mothers' smartphone dependency(MSD) and their children's problem behavior and how children's smartphone dependency(CSD) mediates this relationship. A survey was conducted in the Seoul and Gyeonggi of 300 mothers having children from two to six years old. The results showed that MSD was directly related to both CSD and children's problem behavior, and in particular, had greater effects than CSD on children's problem behavior. CSD was found to mediate the relationship between MSD and children's problem behavior. The results suggest that mothers and their children should be provided with education on the proper usage of smartphone to prevent problem behavior in children, and that the development of preventive programs for smartphone addiction is needed.

Ant-based routing methods belong to a class of ant colony optimization algorithms which apply the behavior of ants in nature to routing mechanism. Since the topology of mobile ad-hoc network(MANET) changes dynamically, it is needed to establish paths based on the local information. Subsequently, it is known that routing in MANET is one of applications of ant colony optimization. In this paper, we propose a routing method, namely EPMAR, which enhances SIR in terms of route selection method and the process upon link failure. The performance of the proposed method is compared with those of AntHocNet and SIR. Based on he analysis, it is proved that the proposed method provided higher packet delivery ratio and less critical link failure than AntHocNet and SIR.

With concerns for consumers' return behaviors affecting internet shopping malls' profits and product management in the internet clothing market, this study is designed to investigate determinants affecting return and path models for return behaviors. For an empirical study, questionnaires are prepared and respondents in their 20s and 30s with internet clothing purchase experience are selected using the convenience sampling. A total of 517 questionnaires are used for the final analysis. Data are analyzed by using SPSS 12.0 software and descriptive statistics, $x^2$-test, discriminant analysis, regression analysis, and path analysis is conducted. The results are as follows. First, ones who have returned after purchasing clothing items in internet shopping reached 63.4% of the total consumers. Respondents returned items with price at 50 thousand won or less stood at 67.2%, and the most frequent return shopping malls are open markets with their return rate at 51.1%. Second, variables such as risk perception, information search, impulse buying, buying experience, and age have a positive effect on return experience. Impulse buying and buying experience turn out to have a significant effect on the degree of return, but risk perception, information search, age, and gender to have an insignificant effect. Return intention is significantly affected by risk perception, gender, and age. Third, the analysis of path model for return experience shows that perceived risk has a positively effect, and information search has a direct effect as well as an indirect effect through buying experience or impulse buying. The analysis of path model for the degree of return shows that risk perception does not have effect, but information search has indirect effect through buying experience or impulse buying. This study is thought to find consumers' return behavior characteristics in online shopping, and help businesses operating online shopping malls to efficiently manage returns and set up strategies against returns.

The purpose of this study was to investigate the determinants of total payment for mental and behavioral disorders patients admitted through the emergency room. Study data was selected from the Korean National Health Insurance sample data in 2009. This data was consisted of 753 inpatients who are 331 inpatients with only main sick(F31-F39) and 422 inpatients with main sick codes(F31-F39) and sub sick(F00-F99) admitted through the emergency room. SPSS v.18 was used for the statistical analysis such as descriptive analysis, t-test, ANOVA, and multiple regression analysis. In multiple regression analysis, significant variables affecting total payment of main sick patients were gender(p<.01), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). Also, main sick patients with sub sick were gender(p<.01), age(p<.001), treatment result(p<.001), path of the emergency room(p<.001), and length of stay(p<.001). These findings implied that it is necessary to build short, middle, and longterm program and system for high risk mental and behavioral disorders groups.

본 연구는, 그 동안 간과되어 왔던 의류 상품의 판촉에 초점을 맞추어, 판촉의 여러 방법 별 소비자들의 반응 정도를 알아보고, 그 반응 경향이 소비자의 인구통계적 특성, 판촉에 대한 태도, 의복 쇼핑 성향, 기타 의복 구매 행동과 연관성을 가지는지를 규명함을 목적으로 한다. 수도권 거주 여성 444명을 대상으로 수집한 자료를 이용해 분석이 이루어졌다. 실증적 연구를 통해 다음과 같은 결과를 얻었다. 첫째, 판촉의 각 방법에 대한 소비자들의 반응 정도는 가격 할인이 가장 높았고 그 다음은 디스플레이, 쿠폰, 사은품, 백화점 패션쇼, 경품의 순서로 나타났다. 가격 할인, 디스플레이, 사은품, 쿠폰, 백화점 패션쇼 등 5가지 판촉 방법에 대한 소비자 반응 정도를 기준으로 군집분석한 결과 판촉에 대한 반응 유형에 있어 차이를 보이는 5개 집단을 규명할 수 있었다. 각 집단의 인구통계적 특성들 중에서는 소비자 자신의 학력과 자녀의 연령만이 집단간에 유의한 차이를 보였으며, 각 집단의 판촉 태도는 집단 간에 유의한 차이를 보였다. 둘째, 각 집단은 의복 쇼핑 성향 및 의복 구매 관련 정보원 이용에서 차이를 보였다. 결론에서는, 실증적 연구의 결과 판촉에 대한 소비자 반응 유형별로 인구통계적 특성, 판촉 태도, 의복 쇼핑 성향, 기타 의복 구매 행동에 차이가 있음을 알 수 있었으므로 의류 상품의 판촉 전략 수립시 표적 집단의 특성에 따라 판촉 방법 선택이나 판촉 정보 전달 경로 등을 조절하는 것이 필요함을 제언하였다. 예를 들어, 신중/경제적 쇼핑 성향을 가지며 판촉에 대한 태도가 호의적인 소비자들에 대해서는 다양한 정보 전달 경로를 통해 가격 할인이나 쿠폰을 제공하는 것이 좋은 판촉 방법이 될 것이며, 쾌락/유행 지향적이고 상표/품질을 중시하는 소비자들에 대해서는 잡지, 인적 정보, 카탈로그 등을 정보 전달 경로로 하여 디스플레이나 패션쇼를 통해 판매 촉진을 할 수 있을 것이다.0.10 $h^{-1}$과 0.09$h^{-1}$h-1이었고, 반감기는 각각 6.93 및 7.70시간으로 측정되었다. 각각의 농도에서 12시간 및 8시간 이후에는 g당 0.19$\mu\textrm{g}$ 및 0.18$\mu\textrm{g}$이하로 떨어짐을 알 수 있었다. Phosphamidon과 profenofos의 급성어독성은 profenofos가 높았고, BCF profenofos가 phosphamidon보다 약 100배 정도 높게 나타났으며, 배설속도는 phosphamidon이 profenofos보다 약 2배 정도 빨랐다.
