This study investigates the effect of in-law relationship on the marital adjustment of married couples by considering family-oriented Korean culture. Previous in-law studies did not consider the influence of another party who did not attend the survey due to sampling limitations. However, the marital adjustment of married couple and the satisfaction of the relationship with parents-in-law are two-way relationships that affect each other and are not one-sided relationships. By considering the non-independence of the couple's data, Actor-Partner Interdependence Model (APIM) was utilized to examine the structural relationship between marital adjustment (marital satisfaction and marital stability) and in-law relationship quality (relationship satisfaction between mother-in-law and daughter-in-law for wives, relationship satisfaction between mother-in-law and son-in-law for husbands) of 203 married couples. Results indicated that a high satisfaction of wives' in-law relationship increased personal marital adjustment as well as husbands' marital adjustment. The husbands' positive relationship with in-laws also increased personal marital adjustment and their wives' marital adjustment. The results of this study can be used as basic data for program development and counseling for healthy in-law relationship as well as educational data for couples intending to marry.

The central government has implemented policies to strengthen the competitiveness of small and medium sized cities for balanced development at the national scale. However, since it is often difficult to enhance the competitiveness through partial projects of each jurisdiction, many local governments collaborate at the regional scale. This suggests that a regional approach is important for the management of small and medium sized cities. On the one hand, the concept of network city suggests that various functional networks can affect the growth of small and medium sized cities. Given this background, the purposes of this study are to delineate regional boundaries at national scale and identify their relations of growth by using functional network and Moran's I index. The study uses the Markov-chain model and cluster analysis to delineate the regions, and Moran's I is employed to identify the relations of growth. The results show that interactions between jurisdictions through networks could be crucial factors for growth of small and medium sized cities, while the networks based on passenger travel and freight movement have different implications. The results suggest that policy makers should not only consider local level investments, but also take the characteristics of networks between cities into account for achieving balanced development and developing regeneration policies.

The purpose of this study was to examine actor and partner effects among infertile couples in determining whether self-esteem affects the degree of infertility-related stress via perceived spousal support. The sample comprised 219 couples who experienced infertility, each of whom completed an online survey. To analyze the data, descriptive statistics, t-test, correlation analysis and APIM (Actor-Partner Interdependence Model) were performed using SPSS 25.0 and Mplus 7.3 program. The main results were as follows. First, the actor effect of spousal support on self-esteem was significant in both husbands and wives. Second, the actor effects of spousal support on infertility-related stress and self-esteem on infertility stress were significant only in husbands. Third, in the association between husbands' and wives' spousal support and infertility-related stress, three mediating pathways via husband's self-esteem were found to be significant. Based on these results, the necessity for a couple-level analysis in infertility research, psycho-emotional interventions for infertile couples, and implications for follow-up studies were discussed.

The purpose of this study was to evaluate the effect of parenting stress on marital conflict in dual earner couples with children in early childhood. Actor and Partner Interdependence Model (APIM) was conducted in order to identify how parenting stress affect husband and wife, respectively and how this make the actor effect as well as the partner effect regarding the marital conflict. The research was conducted with 629 married couples from the forth wave of the Panel Study of Korean Children (PSKC) data. In order to examine the relationships between the variables and to evaluate the appropriateness of the research model, structural equation model was used. The results showed that the parenting stress had significant positive effect on the marital conflict. The partner effect of parenting stress was significantly positive. This result implies that the mutual dependence in dual earner couple's marital conflict and parenting stress should be considered in the process of intervention. In other words, to improve the effectiveness of intervention, practitioners should treat couples together rather than being focused on individuals.

Strategic decisions related to the design of a physical distribution system can be classified into three basic components : facility location, transportation, inventory decisions. In this research the interdependence of those decisions are expressed in a mathematical model such that the total relevant cost of the system is minimized. We suggested a heuristic technique for solving the model. In broad terms, our solution technique combines a heuristic method for determining which candidate DCs to open and an exact method for minimizing costs given a set of open DCs. And we also developed a decision supporting package for the design of a physical distribution system.

This study investigates factors that impact dating relationship stability(DRS) among college students by applying two key concepts from the Interdependence Theory suggested by Kelly & Thibaut (1978; Thibaut & Kelly, 1959), the comparison level(CL) and comparison level for alternatives($CL_{alt}$). This study also examined mediating effects of commitment on the relationship between CL and DRS and $CL_{alt}$ and DRS. The research used a survey data set drawn from 327 college students currently involved in a dating relationship. The collected data set was then analyzed using SPSS software ver. 23.0 and AMOS software ver. 25.0, to produce the descriptive statistics, Pearson's correlations, and path analysis with bootstrapping. First, both CL and $CL_{alt}$ had a significant direct impact on DRS. In terms of effect size, CL's effect size was comparatively larger than $CL{_{alt}}'s$. The mediating effects from the commitment were evidenced. In the model, the commitment partially mediated the relationships between CL and DRS, and $CL_{alt}$ and DRS. The findings suggest that commitment still plays a key role in dating relationships among college students who currently have a romantic partner. The findings of this study show the possibilities in applying the concepts and theory of interdependence to explain current dating relationships among young adults.

The purpose of this study is to explore the mediating effect of violence justification, including actor-effect and partner-effect, in the process where the offense motive affects dating violence. The subjects of this study were 135 unmarried male and female couples aged 19 and over who were dating for more than 3 months, and each couple was subjected to a self-report scale on motives, justification of violence, and dating violence. Based on these paraphrasing, as a result of analyzing the path model using the Actor-Partner Interdependence Model, Men and women's motivations showed a direct effect on their dating violence, while women's motivations showed a significant partner effect on men's violence. The male's motivation also had a significant impact on his dating violence and partner's abuse of dating violence as a mediator for justification of his violence. On the other hand, the mediating effect of justifying violence in women was not significant. These results show that there is a gender difference between the motives for violence and the paths for justifying violence in the sex violence of men and women. Finally, the implications and limitations of this study, and suggestions for follow-up studies were discussed.

This paper shows a empirical results by adopting Kauffman' NK model. First, we find interdependence parameter K is nine in the technological ecosystem Landscape. According to principal component analysis, our technological ecosystem landscape is based on K=N-1 technology structure. Second, to Kauffman NK model, our technological ecosystem landscape is completely uncorrelated each other and contains a large number of local optima. As additional technology rises, the number of local optima rises rapidly. Our results mean that the more complexity in the technological ecosystem landscape, the less effective technology innovation will be in our country's technology system.

The purpose of this study was to examine the effect of the actor and partner effects of the parental sex-role attitude on the parent-child relationship by using the Actor-Partner Interdependence Model (APIM). Specifically, this study focused on the examination of the actor and partner effects of the parental sex-role attitude in married couples with immigrant women who have children under 5 years old. For the analyses, a total of 5,531 couples who participated in the National Survey on Multi-cultural Families were included and the major findings are as follows. First, the couple's sex-role attitude had a statistically significant actor effect on the parent-child relationship. Parents who were more conscious of gender equality displayed a better parent-child relationship and this effect was greater in the case of the father's attitude than the mother's. Second, the father's sex-role attitude had a statistically significant partner effect on the mother-child relationship, whereas the mother's attitude did not. Third, the couple's actor effects were greater than their partner effects and this means that the personal sex-role attitude has a greater impact on the parent-child relationship than the partners' attitude. The implication and limitations derived from these empirical-scientific database results and related studies in educational program of gender equality attitude for multi-cultural families.

In a dynamic business environment, the enterprise mobility solution for a mobile office (EMS) has been adopted to increase the competitive edge of organizations. By using an EMS, performance is expected to be enhanced. However, the related literature has paid little interest to the impact of system quality in an EMS on the information quality produced by the system. On the basis of socio-technical theory, we posited that the system quality in an EMS influences information quality. In addition, we investigated the relationships between the above two qualities, use and job performance by considering task mobility and task inter-dependence as control variables. Survey respondents were from many industries using EMSs. The result of structural equation modeling shows that system quality positively affects information quality, and other relationships in the model are proven statistically significant. We also found that system quality has stronger impacts on use and job performance than information quality does in EMS. However, system quality does not affect use in case both task mobility and task inter-dependence exist. The theoretical and practical implications of the result are discussed in the paper.
