This study aims to find out the argument structure which appears in the type of argument class (teacher- and student-centered) of the high school. The argument structure was compared and analyzed according to analyzing the study achievement and verified the academic achievement related to climate change. The results are listed below. First, the student-centered class is more effective method through the result that analyzed the class type of the teacher in argument-centered class. This result is to suggest more effective method to revitalize the argument activity of students-centered class which students plan for themselves and find more various materials. Second, teacher-centered class is more effective in contrast with argument analysis in the academic achievement test. While this is why the teacher-centered class utilizes an essential data necessary to curriculum in the argumentation, the elements to form the argument increased because students utilized the materials with their interest and concern in the process of proving in the student-centered class. Through the results of the research, it is necessary to develop the argument-centered programs for the science class and the curriculum-centered materials for argument class activity.

[PURPOSE] The purpose of this study was to identify the mediating effects of emotional regulation factors on the relationship between stress and burn-out among college athletes. [METHODS] Four hundred fifty basketball, baseball and soccer athletes registered to the Korean Sport Olympic Committee completed the questionnaires, and 419 responses were used for the analyses after the initial screening process. Using the SPSS Ver.20.0, frequency analyses, exploratory factor analyses, validity analyses, correlation analyses, multiple regression analyses, and hierarchical regression analyses were performed. [RESULTS] Results showed, first, competition stress and athletic support factors positively influenced the emotional drain factor of the burn-out. Also, the impersonalization factor was positively influenced by competition, athletic performance, and athletic support while the personal achievement factor was positively influenced by competition and athletic performance. Next, these relationships between stress and burn-out of the college athletes were reported to be mediated by emotional regulation. Specifically, the regulating effect was displayed when competition, social environment and athletic support factors of stress were interacting with the cognitive reappraisal factor of the emotional regulation. [CONCLUSIONS] These results emphasize the importance of emotional regulation ability when college athletes are in the conditions with high levels of stress and burn-out.

Release competition and development of eco-friendly vehicles have been conducted violently also automaker, it will be a high growth industry of the charger and battery, which is the driving source of the motor of an electric vehicle. Reduces the on-resistance power elements DC - DC converter for battery charger for electric vehicles, must minimize switching losses. Should have a low on-resistance power than existing products. Compare the Super Junction MOSFET and Planar MOSFET, As a result, super junction MOSFET improve on about 87.4% on-state voltage drop performance than planar MOSFET.
이산화탄소 개질 반응에서 ZrO<sub>2</sub>, CeO<sub>2</sub>, Ce-ZrO<sub>2</sub> 조촉매 첨가에 따른 Ni-MgO 촉매의 안정성 향상 연구

MgO supported Ni catalysts have been widely applied to carbon dioxide reforming (CDR) reaction due to their coke resistance. However, activation of Ni-MgO catalyst consumes considerable energy because of its very high reduction temperature. In this study, ZrO<sub>2</sub>, CeO<sub>2</sub>, and CeO<sub>2</sub>-ZrO<sub>2</sub> promoted Ni-MgO catalysts were prepared via a facile co-precipitation method and applied to the CDR reaction. Among the prepared catalysts, the ZrO<sub>2</sub>-promoted Ni-MgO catalyst showed the highest reduction degree and CH<sub>4</sub> conversion. The high catalytic performance of the ZrO<sub>2</sub>-promoted Ni-MgO catalyst is mainly due to easier reducibility, high Ni dispersion, and high specific surface area.

Efficient Investment is important for a company to achieve sustainable growth. This study focuses on high-tech industries where investment decision making is particularly important, and compares the investment efficiency of firms belonging to the high-tech industry with those that are not. Companies belonging to high-tech industries try to make optimal investment with limited resources because investment is very important. However, high-tech industries are highly uncertain and efficient investment can be very difficult. Therefore, this study has analyzed the investment efficiency of companies belonging to the high-tech industries and other industries. It also studied the influence of ownership structure as a way to improve the investment efficiency of the high-tech industries. Using Korean firms listed in KOSPI market during 2002 to 2017, we find the following results. First, firms in the high-tech industries showed lower investment efficiency than those in the non-tech industries, and this inefficiency was significant in both the over-investment and under-investment. Second, the efficiency of investment increased as the ownership of the largest shareholder, which could influence the investment decision of the company, was higher. The results of this study suggest that management investment decisions should be made more carefully in the high-tech industry. It also suggests that the largest shareholders are important for the improvement of the investment efficiency of companies. 기업이 지속가능한 성장을 하기 위해서는 효율적인 투자가 중요하다. 본 연구에서는 투자의사결정이 특히 중요한 첨단기술산업에 초점을 맞추어, 첨단기술산업에 속한 기업의 투자효율성을 분석한다. 첨단기술산업에 속한 기업은 투자가 기업의 생존과 발전에 매우 중요하기 때문에 제한된 자원 범위 내에서 최적의 투자를 수행하고자 노력한다. 그러나 첨단기술산업은 불확실성이 높아 효과적인 투자가 매우 어려울 수 있다. 따라서 본 연구에서는 첨단기술산업과 기타 산업에 속한 기업들의 투자효율성을 비교 분석하고, 첨단기술산업의 투자효율성을 제고할 수 있는 방안으로 소유지배구조의 영향을 연구하였다. 2002년부터 2017년까지 KOSPI 시장에 상장된 기업을 분석한 결과는 다음과 같다. 첫째, 첨단기술산업에 속한 기업은 그렇지 않은 기업에 비해 투자의 효율성이 낮은 것으로 나타났으며, 이러한 비효율성은 과대(과소)투자의 양 방향에서 모두 유의하였다. 둘째, 기업의 투자결정에 영향력을 행사할 수 있는 최대주주지분율이 높을수록 투자의 효율성이 증가하였다. 위와 같은 연구결과는 첨단기술산업에서 경영자의 투자의사결정이 보다 신중하게 수행되어야 함을 시사한다. 아울러, 최대주주의 역할이 기업의 투자효율성 개선에 중요함을 제시하였다는 점에서 의의가 있다.
