This study examined the influence of university students' stress in their daily lives on game addiction, and investigated whether the human relation skills has a moderating effect on their daily life stress. For this study, surveys of 222 university students were collected and analyzed with SPSS 18.0 program. The results of this study are as follows: First, the participants displayed lower human relation skills as the level of stress from the studies increased. In contrast, the participants displayed higher human relation skills as the level of stress from future plans and family relations increased. Second, as the level of game addiction increased, human relation skills were found to be lower. Third, the university students' stress from daily lives had a static effect on game addiction. The participants displayed tendency of game addiction as they had high levels of stress from their studies, financial issues, future plans, values, family relations, and human relations with people apart from their family. Among the listed factors of stress, the stress from the studies most strongly influenced the participants to be addicted to games. Fourth, among the sub-factors of stress in the university students, issues in future plans and family relations significantly control the game addiction. Studies on this area has been insufficient. From the study, it is found that in order to prevent university students to be addicted to games, they must cope well with their stress. Furthermore, this study carries its significance in finding the results that human relation skills contribute as a part of dealing with stress.

Despite that Korea has tried radical efforts in the global flow of regulatory reform in the past twenty years, the result was not radical at all, but rather disappointing. One examines the possibility of paradigm shift in regulatory reform based on new theoretic perspectives. Regulatory reform, one argues, is not just a neo-liberal approach to cut off overflowing regulation. It is a highly conflictual struggle in state order to move from industrial age paradigm to service age paradigm. In the process of the great shift states become integrated into the world of life constructed by the exercise of civil rights. The relation between the civic socio-economic life and the state apparatus became totally different. Past effort for deregulation missed this point without correct recognition of the role of civil freedom and rights in service economy. One treats three typical forms of regulation whereby conventional rules and regulations effectively damper the development of services: reciprocal perspective in contract management, industrial mind in urban and spaces design, and old way of human capital management. According these analyses a new initiative of regulatory reform is proposed to take place at the National Assembly.

The aim of this research is to find out how convergent operation of the learning coaching and compensation system affects the academic self-efficiency and learning performance of university students. In the second semester, a compensation system was prepared based on learning coaching and learning outcomes, made a notice in advance, and conducted a survey before and after operation to measure the academic self-efficacy. In addition, the MLST-II Learning Strategy Diagnosis Examination was conducted on G university students to diagnose the learning tendency. As a result, although G University students felt a reluctance by coaching the learning community and expected negative results during the course of participation in the learning community due to low motivation and low expectation of results, they showed a significant improvement in academic self-efficiency and learning outcomes. Therefore, even students with negative learning tendency will need to consider how to operate these programs in the educational field, as the expert's learning coaching and compensation systems produce positive results for students' academic self-efficiency and learning outcomes rather than leaving them to autonomy.

Film literacy comprises the process of producing a new creation through understanding the elements that make up a film, the content of a film, and a critical and creative thinking process. Film literacy is employed in fields such as composition, science, social studies, and geography, and, additionally, it is used to cultivate humanities literacy and critical thinking skills. Yet despite the large proportion of the film script in the movie, it is not easy to find literacy education cases that use film English as a teaching method. Film English is a practical and authentic material, and is suitable as an English learning material in an EFL context like Korea. However, the approach of using films to teach and learn differs according to the content and genre of a film. Thus, the teacher may have a difficult time organizing and preparing for class. This study suggests six class activities that can be commonly applied to English classes using films based on the areas of critical, cultural, and creative (3Cs) activities. Four hundred and five college students taking Movie English classes participated in the present study and frequency analysis was conducted to find out their preferences through a questionnaire survey. The results from conducting class activities in university liberal arts classes suggest that the most preferred activities of students are related to cultural, critical, and creative, in that order. Creative activities that are far beyond English instruction utilizing various digital tools or providing additional reading materials can be a burden on learners.

In order to improved treatment performance of dielectric barrier discharge (DBD) plasma, plasm + UV process and gas-liquid mixing method has been investigated. This study investigated the degradation of N, N-Dimethyl-4-nitrosoaniline (RNO, indicator of the generation of OH radical). The basic DBD plasma reactor of this study consisted of a plasma reactor (consist of quartz dielectric tube, titanium discharge (inner) and ground (outer) electrode), air and power supply system. Improvement of plasma reactor was done by the combined basic plasma reactor with the UV process, adapt of gas-liquid mixer. The effect of UV power of plasma + UV process (0~10 W), gas-liquid mixing existence and type of mixer, air flow rate (1~6 L/min), range of diffuser pore size (16~$160{\mu}m$), water circulation rate (2.8~9.4 L/min) and UV power of improved plasma + UV process (0~10 W) were evaluated. The experimental results showed that RNO degradation of optimum plasma + UV process was 7.36% higher than that of the basic plasma reactor. It was observed that the RNO decomposition of gas-liquid mixing method was higher than that of the plasma + UV process. Performance for RNO degradation with gas-liquid mixing method lie in: gas-liquid mixing type > pump type > basic reactor. RNO degradation of improved reactor which is adapted gas-liquid mixer of diffuser type showed increase of 17.42% removal efficiency. The optimum air flow rate, range of diffuser pore size and water circulation rate for the RNO degradation at improved reactor system were 4 L/min, 40~$100{\mu}m$ and 6.9 L/min, respectively. Synergistic effect of gas-liquid mixing plasma + UV process was found to be insignificant.
