A new indexing methodology so called KTH-index was developed to quantitatively evaluate a potential level for tunnel collapse hazard, which has been successfully applied to tunnel construction sites to date. In this study, an attempt is made to apply this methodology for validating an outcome of tunnel design by checking the variation of KTH-index along longitudinal tunnel section. In this KTH-index simulation, it is the most important to determine the input factors reasonably. The design factor and construction condition are set up based on the designed outcome. Uncertain ground conditions are arranged based on borehole test and electro-resistivity survey data. Two scenarios for ground conditions, best and worst scenarios, are set up. From this simulation, it is shown that this methodology could be successfully applied for providing quantitative validity of a tunnel design and also potential hazard factors which should be carefully monitored in construction stage. The hazard factors would affect sensitively the hazard level of the tunnel site under consideration.

This research explores the empirical confirmation of the Internet development including from the period of innovation to the time of social-cultural use in today. The research focused on how tradition news media rover about the Internet developed from early to today, and understanding the media characteristics on the each stages from news frame. The research Is designed to conduit content analysis from 1989 to 2004, then this research is divided four(4) stages of the Internet development: innovation, diffusion, commercial usage, social-cultural usage. The results shows that there are significant different coverage by the stages. First of all, the news coverage pattern shift from technology focused on early stages to social usage focused on the later stages. This research confirms that the ratio of the seriation(technology) coverage defined when social usage is increased, on the other hand skeumorphs(social usage and content) coverage is increased in the commercial and social usage stages. This coverage pattern among news media does not such a big different and there is no competitive coverage. Moreover, the news coverage shifted from thematic coverage on early stages to episodic coverage while the number of usage increasing. In addition, the tone of coverage has not been changed significantly.

While college students have great difficulties in preparing for their careers due to the long-term COVID-19 period and the 4th Industrial Revolution, research on positive psychological capital and self-determination factors for employment is insufficient. Based on this, this study aims to investigate the relationship between positive psychological capital and career preparation behavior through self-determination factors for college students. This study conducted a questionnaire for 350 people from April 1 to April 10, 2022, and a total of 345 copies were used for the final analysis, excluding five questionnaires for omission of records. As a result of the study, first, among positive psychological capital, hope had a positive effect on self-determination, but self-efficacy had a positive effect only on competence, and optimism had a positive effect on relationship. have been shown to affect And resilience was found to have a positive effect on autonomy and relationship. Second, among the factors of self-determination, autonomy had a positive effect on both career preparation behavior, and the relationship was found to have a positive effect only on the conversation of career preparation behavior. Using the results of this study, it is expected that it can be used as basic data for the direction and policy for college students to prepare for employment.

The objective of this study has two filds. The first is to examine the effect of native employee's psychological capital on their pro-social organizational behavior in the context of a local subsidiary in abroad. The second is to investigate the moderation effect of non-native managers' leadership type in the relationships between psychological capital and pro-social organizational behavior. The researcher provides the theoretical research model based on the pro-social capital theory and then empirically tests the model by using a valid 334-case collected from three overseas-affiliated-companies in Philippines. The results show that native employees' psychological capital positively and significantly influences to pro-social organizational behavior. Moreover, non-native managers' type of leaderships has the significant moderation effects in relationships between native workers' psychological capital and pro-social organizational behavior. Specifically, stronger relationships are identified in all of relationships when the managers show transactional, transformational and authentic leaderships. Theoretical contributions and practical recommendations are also discussed based on the results of the study.

The study of online social movements is basically concerned about the impact of the Internet on the existing social movements. More specifically, researchers have paid attention to changes in participants, leadership style and movement strategies caused by the Internet. Due to the Internet, networks of the individuals who are geographically scattered or a network of networks have emerged as new movement agents. Researchers have also analyzed a repertoire of collective action adopted by the online social movements. The increase in online social movements calls for a new interpretation of the existing social movement theories such as resource mobilization, collective identity and political opportunity structure. There are still a lot of debate about the impact of the internet on social movement and the resulting changes. Not only the early debate of cyber-optimism and cyber-scepticism, many studies done by the mid-range perspective also suggested different arguments on the impact of the Internet. This discrepancy comes from a relatively short history of online social movement study, which leads to a limited number of case studies and a shortage of date accumulations. In the future, researchers need to place more attention on the unique characteristics of different technologies and comparative studies of online social movements. The study should also extend its focus to a wide range of political systems in order to explain the impact of online social movements on political intermediary organizations and the democracy itself.
