The purpose of this study is to identify the moderate effect of Ego gram between perceived stress and depression from university student according to smokers/non-smokers. The result of study shows the strong association between stress and depression. On the other hand, the moderated effect of Ego gram was different in the smoking and non-smoking groups. In the non-smoker group, the CP tendency which is pursued strictly control by oneself had a moderating effect on depression, and in the smoker group, the A tendency, which had excellent adaptability, creativity, and autonomy, reduced depression. On the other hand, in the smoking group, the AC tendency also showed a significant moderating effect. It is reported that a high AC tendency may cause a feeling of helplessness about the situation and cause negative emotions to conform to reality. This suggests that the individual's ego state to approach emotional state such as stress and depression should be considered together.

The purpose of this study is to determine the moderating effect of counseling class experience on the relationship between an undergraduate's personality characteristics, emotional intelligence, and empathic ability. As a result of verification, having course experience has a moderating effect on empathic abilities, reversing agreeableness from positive into negative. It also has a moderating effect on the influence of empathic concern, making that of an extravert positively significant. The experience of taking a course did not show a moderating effect on emotional intelligence that can be improved by learning. This demonstrates that education in counseling as carried out in universities is inappropriate, and course experience enhances empathic concern only when the student tends to be an extrovert. This implies that the current counseling system is a curriculum suitable for extroverted people. Also, when students have a friendly, amicable tendency, the experience of taking a course lowered empathic ability. This means that an amicable tendency is not a variable influencing educational experience, and that the present curriculum needs to be diversified. Although it is hard to provide a curriculum customized for each individual's characteristics, this study holds significance in emphasizing diversity in the curriculum to allow students to choose a small-group class or the lecture method based on personality or individual tendency.

Transgenic animal을 응용할 수 있는 분야에서는 이식유전자의 기능을 정확하게 규명하고 이를 바탕으로 실질적인 유전적인 개량을 이루기 위해서 이식유전자의 발현을 조절할 수 있는 정교한 system이 필요하다. 유전자의 미세주입법에 의해 transgenic animal을 생산할 수 있는데 이용되고 있는 tissue-specific promoter에 의한 이식유전자의 발현조절은 필요로 하는 시기나 양 등을 인위적으로 조절하고자 하는데 한계점을 갖고 있다. 이러한 이식유전자 발현의 문제점을 극복하기 위해 효모의 recombinase나 미생물의 repressor 단백질과 이들의 binding site인 operator sequence를 이용하여 인위적으로 이식유전자의 발현을 조절할 수 있는 system이 개발되고 있다. Cre/loxP system은 site-specific recombination에 의해 DNA sequence를 제거함으로서 이식유전자의 발현을 조절할 수 있다. 이식유전자 발현의 장소와 양을 조절하기 위해서는 미생물이 이용하고 있는 repressor와 이들의 operator sequence를 적용하여 ligand binary system이 개발되었다. Lac repressor system에서는 isopropyl-$\beta$-D-thiogalactoside (IPTG)가 이식유전자 발현을 조절할 수 있는 positive regulator로서 작용하고, tetracycline-VP16 system에서는 tetracycline이나 유사물질들이 negative regulator로서 이용할 수 있다. 이러한 binary system은 transgenic animal에서 이식유전자 발현의 장소와 시기 또한 양을 효과적으로 조절하는데 적용할 수 있는 것으로 나타났다. 따라서 기존의 binary system과 함께 새로운 regulatory system의 장점을 이용하여 보다 완벽한 이식유전자의 인위적인 조절 system을 이룩함으로서 transgenic animal technology의 실용화를 앞당길 것으로 기대된다.

다양하고 복잡한 기전에 의하여 정교히 조절되고 있는 면역 체계의 비정상적인 기능에 비롯된 자가 면역 질환을 개선, 치료하기 위하여 지금까지 많은 면역 조절제가 개발되어 온 바 있으며, 이들의 면역 조절 기전은 약물에 따라 그 효능에 있어 차이가 크고 독성등의 부작용등으로 인해 그 사용이 현저히 제한되고있는 경우가 많아 보다 안전하고 효능있는 새로운 면역 조절제의 개발은 아직도 매우 중요한 의의를 지니고 있다. 이러한 관점에서 본 연구실에서는 천연물로부터의 새로운 면역 조절제의 검색을 수행하여 온 바 있으며, 그중 Brazilin이 Low-dose Streptozotocin의 반복 투여에 의해 유도되는 당뇨병 상태의 면역 조절 기능에 미치는 영향에 대해서 검색하고자 하였다. 실험의 결과를 종합하여보면, Brazilin은 외부항원 (SRBC)의 유입시 정상 대조군에 비해 현저히 저하되어 있는 T cell의 기능을 정상 대조군 혹은 그 이상으로 증가시키는 효과를 나타내었으며, B cell의 기능 역시 활성화 시키는 것으로 관찰되었다. 이로부터 Brazilin은 Streptozotocin 유도 당뇨병 상태의 면역기능을 정상화시키는 면역 조절활성을 갖는 것으로 판단되었다.

본 논문은 태양광 발전 시스템 중 차동 전력 조절기가 다루는 전력을 최소화하기 위한 LPPT (Least Power Point Tracking) 에 관한 것이다. 두 개 이상의 태양광 모듈에서 그늘짐 등으로 인해 발생 하는 전력 차이를 양방향 차동 전력 조절기를 통해 다루게 되는데, 이 때 태양광 모듈을 입력으로 하는 부스트 컨버터의 스트링 전류를 조절하게 되면 차동 전력 조절기가 담당하는 전력이 최소가 되도록 할 수 있다. 차동 전력 조절기의 용량이 줄어듦에 따라 시스템 크기를 줄일 수 있고, 이와 함께 단가도 감소하는 효과를 낼 수 있다. 본 논문에서는 차동 전력 조절기의 전력이 최소가 되게 하는 LPPT 방법을 PSIM 시뮬레이션과 실험을 통해 입증 하고자 한다.

The purpose of this study is to examine sidedness effects of political Ad message and moderating roles of consumers' persuasion knowledge. To test these research hypotheses, this study conducted experimental designs. 125 undergraduate students were assigned to one of the two experimental groups. The data demonstrate that message types have a significant effect on both reliability toward Ad message and acceptance intention. In addition, consumers' persuasion knowledge plays a significant moderating role between the message types and the dependent variables. The results of this study suggest various implications by indicating political Ad message as an important factor which can enhance customers' positive responses but has been passed over by the previous research. We also indicated the limitations of this study, and suggested the future research directions.

The aim of this article is to examine the relationships between authentic leadership and job satisfaction and to test the moderating effects of co-workers undermining on that relationship. Data were collected from 24th companies in Korea. The sample included 490 employees chosen randomly. Moderated hierarchical regression was used to examine the moderating role of co-workers undermining on the authentic leadership and job satisfaction relationship. The results show that authentic leadership is positively and significantly correlated with job satisfaction. In addition, the results of the hierarchical multiple regression analyses support the moderating effects of perceived employee co-workers undermining with regard to the relationship between authentic leadership and job satisfaction. This study contributes to suggesting the role of co-worker's undermining as a key moderator of their relationship. The theoretical as well as practical implications of the results were discussed with the suggestion for future research.
