정교화가능성모형과 기술수용모형에 의해 정보기술 수용의 설득과정을 시도한 연구들이 이론적으로 미친 영향은 매우 크다. 그러나 이들 연구의 대부분은 횡단면적 접근에 기반한 정적 모형을 사용했기 때문에 시간 흐름에 따른 변수 간의 관계 변화를 적절히 설명하지 못하고 있다. 가령, 교육 프로그램을 통한 정보기술 수용은 일정기간의 시간을 요하는데 설득경로가 유용성의 지각에 미치는 영향력은 달라질 수 있다. 따라서 정보기술 수용과정을 충분히 규명하기 위해서는 기존의 연구모형은 종단적으로 확장되어 시간 흐름에 따른 시스템 사용을 평가해야 한다. 한편 정보기술수용 연구에서 내재적 동기의 중요성이 강조되고 있음에도 불구하고 수용 설득과정에서 내재적 동기에 대한 고려는 별로 없었고 대부분의 연구는 유용성과 같은 외재적 동기를 중심으로 이루어졌다. 본 연구의 목적은 정보기술수용 설득과정의 이해를 넓히기 기존 연구에서 제시된 연구모형에 내재된 동기에 관련된 변수를 포함하고 전체적인 모형을 종단적으로 확장했고, 실증적 검증을 위해 정규 대학과정 과목의 학생들을 대상으로 두 번에 걸친 표본 조사를 하였다.

The purpose of this study is to explore the relation among mother's rearing attitude in infancy, children's self-concept and the relationship with friends in childhood by using the longitudinal data originated by the Korean Institute for Research in the Behavioral Sciences(KIRBS). Specifically, using Structural Equation Modeling(SEM), the causal relation among the mother's rearing attitude in infancy, children's self-concept and the relationship with friends in childhood were examined across a 8-year-period. The subjects were 68 children(38 boys and 30 girls) from the KIRBS longitudinal data. The results showed that mother's rearing attitude in infancy can be consequential environmental variable factor, and children's self-concept do not play an essential intermediate role between mother's rearing attitude in infancy and the relationship with friends in childhood. This study used a newly attempted method in the field of Human Development.

This study explores how married migrant women in Korea create social capital in their everyday lives, and how their social capital influences cultural acculturation. This study performs a structural equation model, using two-year data of female migrant women. The results suggest that network elements, including official supports from public organizations and unofficial supports from personal ties, contribute to creation of perceptual elements, including social trust, community involvement and relations. Also, these two elements of social capital have positive impact on acculturation of married migrant women in Korea. The longitudinal analysis provides a basic understanding of the creation of social capital and the relationship between social capital and acculturation of married migrant women and also clearly suggests the importance of public supports rather than personal supports from family or friends.

Using the 3rd to the 6th wave data from the Korean Children and Youth Panel Survey(KCYPS), we examined the effects of academic characteristics and social relations on the trajectories of the life satisfaction among adolescents. OLS results showed that male students were more satisfied with their lives than female students in the 3rd grade of middle school. As academic characteristics, academic achievement and the level of class adjustment improved life satisfaction but the amount of learning time spent had a negative effect on life satisfaction. However, the effect of academic achievement lost its statistical significance after including variables of social relations. Relationships with parents, teachers, and friends had positive effects on life satisfaction. The longitudinal analysis using the fixed effect estimation also showed a similar result of the associations among the variables to that in the OLS analysis. The life satisfaction gap between male and female students narrowed over time from the 3rd grade of middle school to the 2nd grade of high school. The effects of relationships with parents and friends showed significant effects on both female and male students, but the relationship with their teachers was significant only for female students. Based on the results, we discussed the issues of Korean education related to the life satisfaction among adolescents.

The purpose of this study is to describe how the structural and functional features of social network change among widowed middle and older adults and to examine the effect of personal predictors of the social network change. Data was obtained from men and women between 45 to 98 years of age(N=118) who were bereaved by the death of their spouse since the first wave survey and participated in the second wave survey of the Korean Longitudinal Study of Ageing(KLoSA). The main findings are as follows: First, their social network after the bereavement was strengthened centered around children; for example, the number of adult children living in proximity to the parent, frequency of contact with children, and the financial and non-financial support from children generally increased. Second, the social network change pattern was categorized into four types such as "overall increased type," "children-centered increased type," "children/close relationship-centered increased type," and "stagnation type." Finally, the health condition of the widowed middle and older adults was a strong predictor of the social network change.

This study examined the longitudinal relationship between depressive symptoms and alcohol use based on the tension reduction hypothesis and the intoxication hypothesis considering for path of depressive symptoms on alcohol use and vice versa simultaneously. And this study examined the effect of psychosocial behavior factors (i.e. smoking level, self-esteem, satisfaction with family relationships, and satisfaction with social relationships) on depressive symptoms and alcohol use. Using the data on the Korea Welfare Panel Study for the 1st, 2nd, and 3rd years, this study were estimated using the Latent Growth Curve Model which is helpful for examining differences between the two. The results are as follows: the initial level of alcohol use had a positive impact on the rate of change in depressive symptoms, thereby supporting the intoxication hypothesis. Second, self-esteem and satisfaction with family relationships act as variables with the biggest effect on the initial level and the rate of change in depressive symptoms, whereas other psychosocial behavior factors such as smoking level and satisfaction with social relationship exert the largest influence over the initial level and the rate of change in alcohol use. This study has implications in that it clarified the confused relationship mechanism between alcohol use and depressive symptoms the two. Based on the finding of the study, political and practical implications were discussed.

Customer participation in the service encounter plays an important role in the interaction process. In addition, customer participation is affecting the development of relationships between customer-service provider. Previous researches revealed the role of customer participation through a fragmented and cross-sectional approach, however, given the dynamics of the relationship, it is necessary to identify the role of customer participation from a longitudinal perspective. In addition, it is necessary to determine the cause of the overlap between the antecedent variables and consequent variables. This study aims to identify the relational role of customer participation by clarifying how customer participation affects relationship development from a longitudinal perspective, focusing on trust and commitment variables which are keys to relationship marketing. The related role of customer participation is analyzed through a regression analysis through long-term data. The results of the study showed that commitment(t1) directly had a positive effect on customer participation. However, trust(t1) has been shown to have a direct positive effect on the sub-dimensions of customer participation, such as personal interaction and responsible behavior. Customer participation(t2) affected by this trust(t1) and commitment(t1) again turned out to have a positive effect on trust(t3) and commitment(t3). In conclusion, although customer participation is affected by the relational variables, it can be seen that customer participation is a major factor that can improve the relational variables again through the interaction process. For this reason, a service firm can seek to develop relationships with customers by drawing and utilizing their needs to exchange information and to interact in the service encounter.

Data were collected by peer nomination and sociometric nomination when children were in 4th grade and again two years later, Concurrent results of peer nominations were that prosocial children were more accepted while overtly/relationally aggressive children were more rejected by peers. Peer acceptance of males at Time 1 affected peer acceptance at Time 2. Peer rejection of females at Time 2 wasn't affected by overt aggression at Time 1. Cross-sectional results of social status were that rejected and controversial children showed higher levels of overt aggression than any other group. Popular children were most prosocial; rejected children were least prosocial. In the prospective view, aggressive males remained more rejected than any other group. Rejected children remained least prosocial.

This study aims to investigate peer socialization processes on early adolescents' prosocial behaviors in friendship networks. A longitudinal social network model (SIENA) was used to disentangle socialization process in prosocial behavior. Participants were fourth and fifth graders in South Korea from 39 elementary school classrooms (N=1,040, 48% girls). According to results, students select friends based on similarity in prosocial behavior (peer selection) was found in both prosocial behaviors. Peer influence effects were also observed in prosocial behaviors. Also, moderating effect of social relatedness was significant. In classes with high social relatedness, influence effect of prosocial behavior was significant. As a contrast, prosocial behavior was not socialized in classes with the low social relatedness. Results suggest that peernetwork play a critical role in the co-evolution of friendships, and prosocial behaviors. Findings yielded the importance of the socialization process and promoting healthy peer socialization environment.
