본 연구에서는 K리그 선수들이 팀에 대해 가지는 집단주의적 성향이 팀 성과에 미치는 영향력을 살펴보고자 한다. 특히 성과 창출 과정에서 활력 관계의 매개 역할을 규명하고자 한다. 가설 검증을 위해 국내 K리그 10개 팀 280명의 선수들을 대상으로 설문지를 배포한 후 불성실한 응답을 한 설문지를 제거하여 최종적으로 240부를 자료 분석에 사용하였다. SPSS 21.0과 Lisrel 9.0을 사용하여 빈도분석, 탐색적 요인분석, 신뢰도 분석, 상관관계 분석, 선형회귀 분석, 구조방정식 모형 분석을 실시하였으며 다음과 같은 결론을 얻었다. 첫째, 구성원들이 팀에 대해 지니는 집단주의는 활력 관계에 통계적으로 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 활력 관계는 팀 성과에 통계적으로 유의한 정(+)의 영향력을 행사하는 것으로 나타났다. 셋째, 가설에서 설정한 바와 같이 집단주의가 팀 성과에 영향을 미치는 과정에서 팀 활력 관계가 완전 매개 역할을 하는 것으로 나타났다.

The notions of hyper permeable subalgebraic value and hyper permeable idealistic value are introduced, and related properties are investigated. Given a pair of two numbers in a unit interval, conditions for the pair to be hyper permeable subalgebraic value and hyper permeable idealistic value are discussed. Given hyperfuzzy structures, conditions for their level sets to be subalgebraic energetic, idealistic energetic, right stable and right vanished are considered. Relations between hyper permeable subalgebraic value and hyper permeable idealistic value are studied.

다양한 고에너지 물질이 포함된 폭발 장치를 정확하게 해석하기 위해서는 고에너지 물질의 다양한 연소 현상과 주변을 둘러싸고 있는 고체물질에 대한 대변형 현상을 정확하게 모사하는 것이 필수적이다. 이를 위하여 본 연구에서는 다중물질 각각의 경계면을 level set 함수를 이용하여 정확하게 표현하였으며, 경계면은 ghost fluid 기법을 사용하여 나타내었다. 각각의 물질에 대하여 대변형에 적합한 구성방정식을 사용하였으며, 지배방정식을 고차의 수치해석 기법을 사용하여 해석하였다. 다양한 폭발장치 중 실험적인 데이터를 이용하여 검증이 가능한 rate stick 문제를 해석하였으며, 실험과 유사한 결과를 획득하였다.

The purpose of this study is to develop the life scale of the middle aged homemakers. The life scale are composed of spouse relation 8 items, child education relation 7 items, home economy relation 4 items, homework relation 3 items, selfish health relation 6 items, parent relation 3 items, and interest and social activity relation 4 items. The reliability coefficient of the development scale was Cronbach'α =.83 and the correlations of each demesne was high. For the better future life in this study, the middle aged homemakers are needed the improvement of conjugal relations, the child education, the health, the interest, and the enlargement of social relations. This life scale can help to evaluate their middle age, and to the planning of energetic healthful future, and useful to understanding characteristic and the developmental task of middle aged homemakers.

Recent years have witnessed renewed interest in Africa and public diplomacy has emerged as the vital tool being used to cultivate these relations. China has been leading in pursuing stronger economic partnership with Africa while middle powers such as Korea are also intensifying engagement with the continent. While previous studies have analyzed the implications of China's activities in Africa on advanced powers, none has examined them from the paradigm of middle powers. This study fills this gap by assessing China's activities in Africa, their economic engagement and implications for Korea's interest in Africa. The analysis is qualitative based on secondary data from various sources and literature. The study shows that China's public diplomacy strategy involves a high degree of innovation and has evolved to encompass new tools and audiences. China has institutionalized a cooperative model that permeates many aspects of governance institutions in Africa, enabling it to strengthen their relations. This could also be helping China to adjust faster leadership transitions in Africa. Whereas the US is still the most influential country in Africa, China is influential in economic policies and has outstripped the US in infrastructure diplomacy. This could be because African policy makers align more with China's economic model than the US' mainstream economics. Chinese aid to Africa has been diversified to social sectors that are more responsive to the needs of Africa. Trade and investment relations between China and Africa have deepened, but so does trade imbalance since 2010. China mainly imports natural resources and raw materials from Africa. But this product portfolio is not different from Korea and the US. China's energetic insertion in Africa using various strategies has significant implications for countries with ambitions in Africa. Korea can achieve its ambitions in Africa by focusing resources in areas it can leverage its core strengths-such as education and vocational training, environmental policy and development cooperation.

The compound 3-(2-Mercaptopyridine)phthalonitrile has been synthesized and characterized by IR, UV-vis, and X-ray single-crystal determination. The molecular geometry from X-ray determination of the title compound in the ground state has been compared using the Hartree-Fock (HF) and density functional theory (DFT) with the 6-31G(d) basis set. The calculated results show that the DFT and HF can well reproduce the structure of the title compound. The energetic behavior of the title compound in solvent media was examined using the B3LYP method with the 6-31G(d) basis set by applying the Onsager and polarizable continuum model. Using the TD-DFT and TD-HF methods, electronic absorption spectra of the title compound have been predicted and good agreement with the TD-DFT method and the experimental determination was found. The predicted nonlinear optical properties of the title compound are much greater than those of urea. Besides, molecular electrostatic potential of the title compound were investigated by theoretical calculations. The thermodynamic properties of the compound at different temperatures have been calculated and corresponding relations between the properties and temperature have also been obtained.

KYP 모델은 화약의 폭굉 반응속도를 기술하는 압력기반모델이다. 본 연구에서는 PETN 기반 복합 화약(PBXN-301)의 KYP 모델 및 JWL EOS의 파라미터를 결정하였다. 크기효과를 얻기 위하여 반응 막대 시험을 수행하였고 2차원 하이드로다이나믹 해석 결과와 비교하였다. 해석 결과, 정성적으로 얻어진 LLNL의 구성방정식보다 KYP 모델링을 통해 도출된 파라미터가 PBXN-301 화약의 역반지름에 따른 폭굉파속을 잘 예측하는 것으로 나타났다.

The meridians are energy pathways found in the interior organs of the body leading the bio-electrical energy the periphery of the body for its energetic supply and the meridians connect the individual acupuncture points. The acupucture points in turn serve for the interference with the bio-electric energy, thus made it measurable. It has been developed to a stage where one could stimulate the acupuncture-points in order to achieve organ effects in the body. To the contrast, Dr.Niboyet proved that the human skin contains points varing in their electrical roperties as to their surroundings. He also tried to send direct current through the skin taken from the body and derive it at other places of the skin characterized by the above mentioned meridians and acupuncture points. The body produces a potential in the organs to reach the acupuncture point via the meridians. The charge on the individual acupuncture point caused by the exactly difinable current of our mesurement device, creates a state of blance between the irritational potential, both of whcih are which are opposite to each other. The body processes the irritational current in the acupuncture point. Voll and Werner, as early as 1953, developed an instruments for applying electro-acupuncture on the skin without needle picks and the teaching from part of modern medicine after developing over recent years. Electro-acupucture is a comprechensive fterm for all procedures based on mesurements or thrapy derived from Oriental acupuncture, using modern electronics. As a result, I found the phenomena of the meridian during the disease. And It seems to be closely related between the meriduan and the disease. I think it must be researched profoundly and for the long time.
