This study aims to prevent the serious threat from dangerous person or group by responding or blocking or separating illegal activities by use of SNA: Social Network Analysis. SNA enables to identify the complex social relation of suspect and individuals in order to enhance the effectiveness and efficiency of investigation. SNS has rapidly developed and expanded without restriction of physical distance and geo-location for making new relation among people and sharing large amount of information. As rise of SNS(facebook and twitter) related crimes, terrorist group 'ISIS' has used their website for promotion of their activity and recruitment. The use of SNS costs relatively lower than other methods to achieve their goals so it has been widely used by terrorist groups. Since it has a significant ripple effect, it is imperative to stop their activity. Therefore, this study precisely describes criminal and terrorist activities on SNS and demonstrates how effectively detect, block and respond against their activities. Further study is also suggested.

This study was carried out utilzing ability of sole carbon sources in soil microbial communities used by Biolog GN microplate. Cluster analysis showed that soil microbial cornmuties were categorized into three groups as forest, non-forest soil and naked soil of microbial group. Soil microbial commutites in a forest soil of Qirercus mongoIica was divided into another group microbial communites in Qirercus dendata vegetation soil and Pinus dnzsqlora vegetation soil by Multidimensional scaling(MDS). Generally, sole carbon utilzing abilties were higher in order of polymer, amino acids and carboxylic acids, but it was lower in amides substrates carbon group. From the result: it was supposed that metabolic diversity of microbial communities was corresponded to vegetation succession.

As a rapid rate of social change and competitive, paradigm of industry environment manufacturing products and services is shifted. Engineers design, develop, manufacture the products and services are strongly asked competency of different new creative practices. This means while industrial structure has been shifted from mass production to various allied production and social engineering based production, qualifications of engineers are required to individual creative competency as alternatives. In order to improve the competency, engineer become the creative people have ability to develop the professional knowledge competency and expand the competency to convergence the new product and services with sensing the life and social structure shift, human engineering, psychology, and emotion. For the competency, we develop the training program "improving convergence, creativity through Art." we intend that the program should be composed of creative engineering mechanism combined creative arts mechanism. It has been operated to the engineers for 17 weeks. we will discuss the program result and research direction and utilization in depth.

This study aimed to explore the trajectories of economic preparations for the aging among people with physical disabilities and to identify the determinants according to the Andersen model. For this study, data were drawn from Panel Survey of Employment for the Disabled (PSED). A total of 1,847 samples were used from the second to the eighth wave. Latent class growth model was conducted to explore the longitudinal change classes for the disabled, and the multinominal logistic regression analysis was conducted to examine the influence of the determinants. As a result, four classes were identified: preparation decrease group, continuous non-preparation group, preparation increase group, and continuous preparation group. Each group was found to be associated deferentially with education level, family income, socioeconomic status, employment, home ownership, national basic livelihood security recipient status, and ADL. These findings proposed the practical and political implications for the strategies concerned with facilitating the economic preparations for the aging among the disabled.

These days, increasing information and communication ethics related crimes frequently covered by mass media are calling for information and communication ethics education. Education scholars have been doing a lot of studies on the measure to practice information and communication ethics education. There is a need for the courseware that can integratedly use information and communication ethics education methods, and this study aims to present courseware in case-based way as an alternative. This study aims to develop and apply a case-based program for information and communication ethics education amongst elementary schoolers, and to verify the effect. For this purpose, two groups that turned out to be homogeneous through a pre-test with information-listing courseware and case-based courseware were chosen and given education. And then, the two groups were compared though a post-test, and the effects of the programs was verified through pre- and post-paired test on each group.

This study examines the effects of mindfulness training on job stress, burnout, and teacher efficacy for middle school and high school teachers. For this study, twenty-four middle school and high school teachers were divided into experimental and control groups. Data analysis was performed using a Mixed ANOVA for teacher's job stress, burnout, and teacher efficacy according to pre-training, post-training and delayed post-training periods. As a result, we found support for time interval and between-group interaction effects for all the dependent variables. In order to investigate any delayed effects, a t-test was performed to analyze measurements taken one month after the completion of training period. The delayed post-training results indicated a significant effect between pre and post scores, meaning the program effects were sustained. Therefore, this study indicates that the mindfulness training program implemented in this research is an effective method for preventing job stress and burnout, as well as influencing the efficiency of work performance for middle school and high school teachers.

For the last 70 years, the U.S.-led bilateral security system, or "Hub-and-Spokes" system, has been applied to Northeast Asia, and the system has been successfully settled in terms of stability and economic achievements of the region. Given the increasing complexity of the security environment of East Asia, it is plausible to consider the possibility of a security system shift from bilateral alliances to collective security. In order to analyze the driver of collective security system, this study developed three factors of formation and development of collective security system - main threat, intensity of the threat, and confidence among countries in the system - by reviewing international political theories related to security cooperation. Comparing the formation, development, and achievements of NATO and SEATO, the study figures out that the existence of the main threat, the high intensity of the threat, and the strong confidence among countries in the security system are the primary drivers for a successful collective security system. Based on the result, the study also analyzed the possibility of a security system shift in East Asia. Considering contemporary international conflicts such as U.S.-China strategic competition, Russia-Ukraine War, and growing threats posed by North Korean nuclear and missiles, the study anticipates that the necessity of a collective security system that will replace the current security system of the region would arise. Still, although some issues between countries should be overcome, the growing intensity of the threats will promote cooperation among countries by improving their confidence.

This study was a non-equivalence-based Quasi experimental study comparing the difference in communication ability, emotional intelligence (EQ), self-esteem, and interpersonal abilities between an experimental group with communication training and a non-control group. The subjects of the study were nurses working for D university hospital located in C city and comprised an experimental group of 21 people and a control group of 21 people. From April to May 2017, the experimental group took communication training programs, which were designed to improve communication capacity, emotional intelligence, self-esteem, and interpersonal ability for a total of four sessions (for 2 hours a week), and pre-post examination was conducted for the validity of the study. For data analysis, the SPSS for Windows 23 was used for the mean and standard deviation of pre-post tests, and U-test of the independent sample Mann-Whitney and the Wilcoxon code order test of the corresponding sample were carried out. The study results indicate that, compared with the control group, the experimental group showed communication capacity (Z=-3.361, p<.05), emotional intelligence (Z=-2.209, p<.05), self-esteem (Z=-1.633, p<.05), and interpersonal relationship (Z=-2.577, p<.05). After the communication training program, scores of communication capacity, emotional intelligence (EQ), self-esteem, and interpersonal competence of the experimental group increased significantly, and all hypotheses were supported. These results suggest that nurses' use of communication training experience in performing nursing work in a clinical setting would improve communication skills, emotional intelligence (EQ), self-esteem, and interpersonal skills and provide therapeutic communication and effective nursing, thereby enhancing patients' satisfaction and contributing to the improvement of nursing quality.
