This study examines the formation and change of relational trust among Korean adolescents using indigenous psychological perspective. Among adolescents, we examine the basis of trust of their parents, friends and teacher and also their trust in people and institutions. A total of 968 adolescents (227 elementary, 284 middle school, 213 high school, and 244 university students) completed a questionnaire that contains the Relational Trust Scale developed by Kim and Park (2004a), Generalized Trust Scale developed by Yamagishi (1998) and a scale measuring trust of people and institutions (Kim, Helgesen & Ahn, 2002). The results are as follows. First, adolescents trust their parents due to their sacrifice, followed by their counsel and advice, dependability, consanguinity and respects. They trust their teachers due to their counsel and advice, followed by respect, sacrifice, and mutual trust. They trust their friends due to their advice, followed by empathy, mutual trust, dependability, friendship and sacrifice. Second, trust of their parents are highest among the elementary school students and lowest for the middle school students and lower for older age groups. The trust in teachers are highest among the elementary school students and lowest among the middle school and university students. In contrast, trust in friends increase from elementary school students to older age groups. Third, among trust in people and institutions, they are highest for parents and family and lowest for politicians and political parties. Except for trust in friends, trust of significant others and institutions (family, teachers, neighbors, company executives and politicians) is highest among the youngest age group and it decreases with older age group. Fourth, Yamagishi's generalized trust was highest among the older age groups (high school and university students). The patterns of results for relational trust and generalized trust is different and it points to the importance of understanding trust from the indigenous psychological perspective.

Sandfill at reclaimed sites is usually formed by more than one placement method. Reclaimed sandfill often shows highly variable profiles and the cone penetration test is most commonly used for site characterization. Correlations between cone resistance and geotechnical parameters for sand are influenced by in-situ stress level and it is important to incorporate stress level effect. In this study, cone penetration tests were performed at several elevations from the top of a 10m high surcharge, which was later removed step by step. In order to establish more reliable correlations between cone resistance and geotechnical parameters for sand, different ways of normalizing cone resistance by the corresponding in-situ vertical stress were investigated.

This article examines the role and influence of educational achievement on Korean society and its future. Four major factors that associated with and influence educational achievement in Korea (i.e., trust, efficacy beliefs, quality of life, and societal transformation) are reviewed. First, the role of educational achievement on establishing a basis for trust in Korean society is examined. By reviewing studies of perception of Korean society, people and institutions, the importance of establishing trust in Korean society is outlined. Second, the role of efficacy belief in promoting educational achievement is examined. The importance of collective efficacy, at the adolescent, adult and political levels is emphasized. In addition, the concept and application of self-efficacy for teachers and parents is reviewed. Third, the role and influence of educational achievement on quality of life is outlined. Studies indicate that educational achievement plays an important role in improving the quality of life. The pressure to achieve, however, can have negative impact on stress and mental health and support systems need to be developed to alleviate their impact. Fourth, the future and prospects for Korean society through educational achievement is discussed. Through education, the importance of bridging the divide with North Korea is an important agenda for the future of Korean society. Finally, the importance of indigenous psychological perspective in understanding Korean society and providing direction for the future is discussed.

The purpose of this paper is to explain and identify how service trust about enterprise of internal employees influence on management performance by investigating relationships between service trust in internal organization of enterprise, job commitment, customer service behavior, management performance. A survey study was conducted to collect the data with sales forces of at domestic major pharmaceutical companies. Analysis of structural equation modeling with AMOS 18.0 was performed to test the research hypothesis. The results of the study are as follows: service trust in internal organization of enterprise are positively associated on both job commitment and management performance, but it was negatively associated on customer service behavior. Job commitment was positively associated on customer service behavior but it was not influences on management performance. And customer service behavior was positively associated on management performance. Therefore, service trust in internal organization of enterprise was direct influences on management performance and it was also effects on through job commitment and customer service behavior. To sum up, if employees are devote themselves in work of their organization, service behavior on their customer of employees will be higher, and then management performance will be achievement. So, it have to reinforce job commitment on employees in order to achievement high performance of management through sales.

The present study identified determinants to user acceptance of artificial intelligence(AI)-based news anchor. Our conceptual model included three constructs of ability, benevolence, and integrity to determine whether these three constructs are predictive of trust perceived from AI news anchor. This work further examined the influences of social presence, anthropomorphism, perceived usefulness, understanding as well as trust as immediate determinants to user acceptance. The conceptual model was validated on survey data collected from 513 respondents. A series of scale refinement process was conducted by the examination of data normality, common method bias, structure of latent variables as well as internal consistency. In addition, a confirmatory factor analysis was performed to assess the extent to which the sample data collected from survey study measures the constructs adequately. The results from the analysis of structural equation model indicated that, (1) two constructs of ability and integrity were found to be significantly predictive of perceived trust, and (2) anthropomorphism, perceived usefulness, and trust emerged as significant and positive predictors of user acceptance of AI-based news anchor.

The purpose of this study is to explore the factors affecting the social capital of youth and to draw implications for the policies related to development of the social capital of them. To this end, we utilized the OLS regression model and the quantile regression model exploiting the 12th year dataset of the Korean Education & Employment Panel(KEEP). First, this study shows that the effect on trust is higher than that of the counterpart when the case is a) unmarried, b) with the high level of education, c) with a large asset, d) with high self-respect and the satisfaction for financial situation, and e) social media user. On the other hand, the higher the monthly average income, the lower the trust level. In addition, when the cases are grouped into 25 quantile, 50 quantile, and 75 quantile according to the level of trust, it is revealed empirically that the factors affecting social capital formation are somewhat different. Second, this study also shows that the effect is higher in a specific condition. The effect is higher compared to the counterpart when the case is a) male, b) with children, c) metropolitan city resident, d) non-employee, e) with a large asset, f) with high level of happiness, g) with high expense of purchasing books, and h) social media user. As a result, it is found that there are no personal characteristics that have statistically significant influence on students belonging to the 25th quantile of social capital. This study suggests that, in order to support the formation of social capital of Korean youths, it is necessary to enhance their psychological satisfaction and to provide cultural support or policies. In addition, it suggests that a tailored social capital accumulation program is needed according to the level of social capital, and the support for this need to be changed according to the amount of social capital of young people.

In recent years The importance of information security management for securing information collection and analysis, production and distribution is increasing. Companies are assured of confidence in information security through authentication of information Security Management System. However, level assessment and use of domains that make up the management system is limited. On the other hand, the security maturity model is able to diagnose the level of information protection of the enterprise step by step. It is also possible to judge the area to be improved urgently. It is a tool to support goal setting according to the characteristics and level of company. In this paper, C2M2, which is an example of security maturity model, is compared and analyzed with Korea Information Security Management System certification. Benchmark the model to check the level of information security management and derive the priority among the items that constitute the detailed area of information security measures of ISMS certification. It also look at ways to check the level of information security management step by step.

The rapid changing technology and globalization allow consumers get information and new products or services faster, have more choices than before, which might be causing more competitive and more uncertain demand. The relationship quality between enterprises positively influence the relational performance. Through this research, enterprises should realize the importance of relationship learning to improve the competitive advantage. Also this research provide the strategic solutions to promote the relationship learning. this is considered to be able to present an improved directionality of the relationship between the buyer and the supplier. In addition, from the perspective of policy, this research provides implications for large enterprises and SMEs to promote their coexistence relation. The empirical model of this paper is established on basis of previous research. The empirical results show that: first, as the influence factors, relation solidarity level, environmental uncertainty, learning intension affect relationship learning, whilst special transaction assets influence information shared and relationship memory and have no effect on mutual understanding; second, relationship learning influence on relational performance and this influence relation becomes stronger if the relationship trust is higher.
