This study examines the impact of political connections of Chinese listed firms on CSR(Corporate Social Responsibilities) activities. Firms recognize the political connections as 'non-market strategy' and actively utilize various benefits obtained through them for management activities. In order to utilize these political connections, there is a need for firms to implicitly perform the government's social policy obligations in return for their benefits. In particular, CSR activities in China are one of the government-led social policies unlike in the West, and the government wants firms to solve social problems through active CSR activities. In this background, this study empirically verifies whether firms with political connections are actively carrying out CSR activities required by the government from 2013 to 2019. As a result, Chinese listed firms with political connections have a positive effect on CSR activities. Especially, those with political connections with central government carry out both government benefits and social policy obligations.

If traditional Korean villages or residential districts have formed a community on the ground of coexisting with nature, there is a different historical development process in which many European cities have created residences for multi households on the basis of roads and blocks in fortresses. Along with the modernization of society together with large-scale housing supply, the urban landscape of series of large apartment complexes has become universal views of our urban structure; thus, the viewpoint that small and medium-sized block-based collective housing, which are more common urban structures in European cities can be linked to the improvement of urbanity and neighborship is examined. Through the process, the possibility of expanding collective housing supply based on small and medium-sized blocks as an alternative method other than complex-type apartments based on superblock, I would like to make meaningful in terms of how we can change the fundamental mutual relationship with our lifestyle and the tangible change of collective housing types which has large impact on our lives.

Although the recent interest in and favor for natural burial has increased, there are still few who choose it as a funeral. The purpose of the study is to supply necessary information to promote the choice of natural burial. For this a survey of 430 students and residents was conducted in Daejeon. The result of the research is as follows. First, there is a significant difference in use intention of natural burial by age and religion. People under the age of 30 and Catholic believers recorded the highest score in use intention of natural burial. Second, there was a significant difference in information on natural burial by age or religion, in religion and philosophy by age, in physical environment by sex or age, and in conservation by sex or age. In general, the lower the age, the higher the positive perception of natural burial was. While females had a more positive perception of physical environment than males, males had a more positive perception of conservation than females. All sub factors of the perception of natural burial such as information on natural burial, funeral style, religion and philosophy, physical environment and conservation had a significant and positive effect on its use intention. However, ratio skew showed that religion and philosophy had the strongest effect on use intention of natural burial, followed by funeral style, physical environment, conservation, and information on natural burial.

As its high functional properties to be used as medicine or food, the cultivation of Agaricus mushroom has been expanded and iぉ commercialization required better storage methods that can extend its functional and nutritional value for longer period. We selected drying as the most plausible method to meet such requirement, and several drying conditions were investigated to locate the optimum drying condition that can be used to keep the quality of mushroom. Drying temperature of 50$^{\circ}C$, 60$^{\circ}C$, 100$^{\circ}C$ were selected to trace the drying time required to achieve the moisture content of mushrooms less than 10%. The drying temperature at 50$^{\circ}C$ required 29 hrs of drying time, while 100$^{\circ}C$ required only 10 hrs of drying tune. However, their quality characteristics on the following categories, on the degree of browning and color were investigated to find the optimum drying condition. In addition, sensory evaluation was conducted to evaluate the quality of dried mushrooms produced by each drying condition. The browning of the mushroom was evidently increased as the higher drying temperature was used and 50$^{\circ}C$ drying produced the most desirable quality of all in pileus or stipe. The aeon of browning intensified by drying temperature was comparable to the result of whiteness index value, which resulted lower L values as drying temperature increased. and the 50$^{\circ}C$ drying resulted the most highest L values among all drying samples. As the browning and whiteness results implied, the sensory evaluation result gathered from the present research indicated that the 50$^{\circ}C$ drying was the most favorable drying condition by scoring the most highest average scores on flavors, color, appearance, and overall acceptability conducted by the 10 evaluation panels.

Based upon the first national sample of adult men and women, the study aims to examine the prevalence of chid sexual abuse in Korea and factors related to the incidence of child sexual abuse. The results of the study show that 20.8% of the sample experienced one or more types of sexual abuse in their childhood, which indicates that Korean society is not any longer immune to child sexual abuse. With regard to how to cope with sexual abuse, "not informed to anyone and did not get any help at all" is the most major one for all types of sexual abuse. Even those who got help were reported to depend heavily upon private routes such as parents, relatives, or friends, indicating the urgency of establishing systematic intervention schemes for the problem. The results of a logistic regression analysis show that gender of the child, involvement in delinquent behaviors, economic status of the family, number of siblings, and residence in high-crime region are significantly related to the incidence of child sexual abuse. These results of the study would be expected to provide a useful guideline for developing policies or intervention programs aimed to prevent or address child sexual abuse.

부산에서 북동쪽으로 대략 25km 떨어진 지점에 위치하고 있는 일광광산 부근의 지질은 백악기 화산암ㆍ퇴적암 그리고 이를 관입한 화강암류와 이 암주 내에 발달하는 구리-중석을 함유하고 있는 각력파이프광상으로 이루어져 있다. 일광광산의 화강암류는 거의 타원형으로 felsic한 중앙부와 mafic한 양상의 주변부로 나뉘어지며, 암주 내에 수직적인 원통형의 각력파이프가 광화대를 이루고 있고, 그 주변에는 모암변질대가 발달되어 있다. 각력파이프를 충진하고 있는 vein과 화강암의 중앙부에는 전기석이 풍부하게 산출되고 있다. 일광광산에서 산출되는 전기석은 야외 관찰시 각력파이프 중심에서부터 외곽부쪽으로 전기석의 풍부함이 감소하며 산출형태도 달라진다. 파이프에서 대략반경 150m내에서 전기석은 침상형 의 방사상 모양 내지 rosettes형으로 풍부하게 산출되며, 화강암내의 mafic한 암편을 치환한 형태로 산출되기도 한다. 암주의 중앙부 주변부에서는 거의 미세한 구상형으로 산재되어 나타나고 있다. 전기석은 복잡한 화학식 {(Na, Ca)(Fe, Mg)$_3$(Al, Li)$_{6}$(BO$_3$)$_3$Si$_{6}$O$_{18}$ (OH, F)$_4$}을 갖는 붕산 규산염광물이다. 이러 한 다양한 성분은 마그마의 진화과정, 모암의 특성, 온도, 압력, 성분과 같은 물리ㆍ화학적 성질에 따라 전기석의 성분이 체계적으로 변하기 때문에 모암과 전기석 기원과의 상관관계를 파악할 수 있다. 파이프 부근의 화강암류는 현미 경상에서 전기석이 석류석과 같이 풍부하게 나타나며 장석들은 변질받은 상태로 세리사이트, 녹렴석으로 나타나고, 흑운모와 각섬석은 녹니석화되어 변질된 상태를 보이고 있다. 파이프 중심에서 외곽부로 갈수록 전기석의 함량은 줄어들고 있고 장석들이 알바이트ㆍ칼스베드 쌍정을 보이며, 흑운모가 각섬석보다는 우세하게 나타나고 있다. 전기석은 주상 결정, 자형 내지 반자형의 입자로 다색성을 보이며, 결정 중심에서 가장자리로 갈수록 파란색과 황갈색의 광학적 누대구조를 관찰할 수 있다. 일광광산에서 산출되는 전기석에 대한 현미경 관찰은 열수기원임을 지시하고 있다. 야외조사와 현미경 관찰의 예비조사에 의하면 일광광산의 전기석이 형성된 환경은 다른2가지 화학적인 저장소의 혼합 효과의 결과로 생성되어진 것으로 예상된다. 일광의 화강암류를 만든 마그마는 전기석을 형성할 만큼의 Fe-Mg성분이 충분하지 않았을 것이다. 화강암 내에 흑운모와 각섬석의 결정작용에 의해 마그마의 Fe-Mg성분이 고갈되어지고 이로 인해 그 함량이 감소하며 상대적으로 마그마 내에 남은 붕소(B$_2$O$_3$)는 열수로 용리되고 흑운모, 각섬석과 평형을 유지하며 열수에 남아있게 된다. 잔류용융체에 남은 붕소의 함량은 전기석을 만들기에 충분함에도 불구하고, Fe-Mg 함량이 부족하여 마그마 기원의 전기석 결정을 만들 수가 없다가 광맥이 형성된 시기에 또 다른 열수가 공급되면서 이전의 평형이 깨지고 기존의 흑운모와 같은 염기성 광물이 붕소(B)를 함유한 새로운 열수와 반응하여 전기석을 형성한 것으로 예상한다. 앞으로 전암과 광물에 대해 지화학적 연구를 통해 화강암류와 전기석과의 지화학적 연관성, 주성분 원소와 열수의 특성과의 상관관계, 전기석의 기원(마그마 기원인지 열수기원인지)이 보다 정확하게 파악될 것이다. 마그마 진화에 따른 전기석의 성분변화와 기원을 이용하여 일광광산의 동광화대를 형성한 마그마 계에서 열수계로 이어지는 지질학적 과정을 이해할 수 있을 것이며, 암석 성인론적 지시자로서 어떠한 중요성을 갖는지 논의되어질 수 있다.

Ten axonic isolates of Trichomonns uaginolis were subcutaneously injected to the BALB/c mice in order to assess their pathogenicity by means of so-called "mouse assay" method. All the isolates revealed neutral and acid proteinase activities both in their Iysates and in culture media, but the specific activities of both proteinases in the severely pathogenic group were significantly higher than the mildly pathogenic group (p < 0.05). In the SDS-PAGE system in which the electrophoretic gels contained 0.4% gelatin as the substrate, five different handing patterns of trichomonal proteinases were detected, and the patterns were closely related with the pathogenicity of the isolates of T. vosinalis. All five bands might be regarded as cysteine proteinases group in the inhibitor assays. The cytotoxicity of the Iysates of T. vaginalis to the target Chinese hamster ovarian (CHO) cell line was also significantly different according to the pathogenicity of the isolates, and generally lower in the Iysates treated with cysteine proteinase inhibitors than in the control Iysates. In summarizing the results, it might be considered that the proteinases of T.vaginalis showing five electrophoretic banding patterns are closely related with the pathogenicity and cytotoxicity of the isolates of T. voginolis.
