The purpose of this study is to explore the effects of difference in urban tree plantings on microclimate amelioration, and to suggest essential information for quantifying urban energy budgets and energy savings. This study was focused on measuring and analyzing air temperature and relative humidity in summer. Daytime air temperatures at places with 8%, 24%, 44%, 79%, and 100% cover of woody plants were, respectively, $0.6^{\circ}C,\;1.3^{\circ}C,\;2.4^{\circ}C,\;3.5^{\circ}C,\;and\;4.8^{\circ}C$ cooler, compared to a place with 0% cover. A 10% increase of woody plant cover was estimated to reduce the temperature by approximately $0.55^{\circ}C$. The temperature reduction effects were relatively greater between places with lower cover of woody plants than between those with higher cover. Woody plant cover and crown volume were the appropriate indicators which quantified the effects of tree plantings on air temperatures, based on the correlation analysis. Regression equations to estimate temperature change ($Y:^{\circ}C$) using woody plant cover ($X_1:%$) or crown volume ($X_2:m^3$) as independent variables are as follows: $$1nY=3.3233-0.0018X_1\;(r^2=0.99,\;p<0.0001)\;Y=27.5297-0.0019X_2\;(r^2=0.96,\;p=0.0007)$$

Glabridin, a compound of the flavonoid, has shown outstanding skin-whitening and anti-aging properties, but its water insolubility limits its wide application. Therefore, glabridin liposome (GL) has been developed to improve its poor bioavailability, while there are few studies to evaluate its amelioration of UVB- induced photoaging. This study is performed to investigate the amelioration of GL against UVB- induced cutaneous photoaging. The prepared GL has a spheroidal morphology with an average diameter of 200 nm. The GL shows lower cytotoxicity than glabridin, but it has a more effective role in inhibition of melanin. Moreover, the application of GL can effectively relieve UV radiation induced erythema and leathery skin, associated with the down-regulated expression of inflammatory cytokines (TNF-α, IL-6 and IL-10). Taken together, these results demonstrate that GL has potentials as topical therapeutic agents against UVB radiation induced skin damage through inhibiting inflammation.

The oral administration of deer horn extract was proved to cause a considerable amelioration to the impairment of hepatic oxidative phosphorylation and to the decrease of ATP content in liver tissue induced by cholesterol ingestion. Deer horn extract was shown to accelerate considerably incorporation of acetate-1-C$^{14}$ into cholesterol in liver tissue and it tends to restore a decrease of GOT activity of liver tissue, caused by cholesterol administration. Histological examination showed that deer horn extract had a remarkable preventive effect against fatty infiltration of organs such as liver, heart, spleen, and adrenal gland of cholesterol given rabbits.

This study was carried out to find the problems of assessment on terrestrial ecosystem part in environmental impact analysis(EIA) and to suggest the proper amelioration measures by analyzing 19 environmental impact statements(EIS) published during the period from 1991 to 1994. The results obtained from this study were as follows. Field survey for the investigation of fauna and flora in project areas should be conducted at least 3 times a year and name of investigator should be written on the EIS clearly. Increase or decrease in degree of green naturality and productivity cannot be an absolute criteria for expressing the amount of changes in ecosystem. Evaluation for the ecosystems and their composition in project area is more important than presenting merely the increase or decrease in degree of green naturality and productivity. Alleviation measures in 19 EISs analyzed in this study were summarized into 6 types: They are establishment of landscape plan, transplanting of useful trees preservation of big tree and protected species, restoration and preservation of existent vegetation, establishment of soil conservation measures and diminution of the impact on animal. However, they were somewhat insufficient because they wouldn't suggest the alleviation measures in detail. The more positive counter-proposals are needed to decrease the impact of the project on terrestrial ecosystem.

본 고에서는 우리나라 폐 석탄광 광산배수의 자연정화처리시설현황과 향후 광산배수 수질개선을 위한 기술수요를 전망하였다. 우리나라 폐 석탄광에서는 현재 약 8만톤의 갱내수가 유출되고 있으며 약 50톤/일 이상 갱내수에 대해서 자연정화시설을 설치하여 갱내수 수질개선사업을 추진하고 있다. 13개 광산에 설치된 자연정화시설의 현장수질분석 및 설계내용을 검토한 결과 SAPS 공정이 Fe의 재용출 현상이 없고 성능면에서 편차가 적어 광산배수의 중화 및 금속 정화에 핵심 공정으로 파악되었다. SAPS 의 정화성능 및 수명에 미치는 물리적 영향은 슬러지 누적에 의한 투수 계수 감소와 체류시간 등이었다. 향후 자연정화시설의 성능을 지속시킬 수 있는 기술개발과 오염부하가 큰 갱내수 처리기술과 채굴적 현장 수질개선 연구가 필요할 것으로 판단된다.

Homoeopathically prepared Condurango 30C is traditionally used in amelioration of certain types of cancer by homeopathic practitioners. In this study, ability of Condurango 30C in amelioration of the conventional benzo[a]pyrene (BaP)-induced lung cancer in rat has been tested. After one month of scheduled oral feeding of BaP, lung cancer is routinely developed after four months in rats. Tumorbearing rats were then treated with Condurango 30C for the next one ($5^{th}$), two ($6^{th}$) and three ($7^{th}$) months, respectively, and sacrificed. Efficacy of post-cancer treatment by Condurango 30C was evaluated against controls (placebo) by different study parameters like: body and lung weights, number and diameter of lung tumour nodules, lung architecture, DNA damage, anti-oxidant activity and reactive oxygen species (ROS) accumulation. Administration of this homeopathic remedy caused increase of body weight and decrease of lung weight, decrease in number and diameter of lung tumour nodules, particularly after one and two months of drug treatment. BaP intoxication significantly increased lipid peroxidase (LPO) with concomitant decrease in activities of different antioxidants, while Condurango 30C administration certainly reduce their levels than normal and cancerous groups, notably after one and two months' of drug treatment. Condurango 30C showed capability to induce ROS-mediated cell death evidenced from the study of ROS activities at different time-points. Further, the remedy possibly achieved its anticancer goal through mediation of DNA-nicks that possibly led cancer cells to the apoptotic pathway. Thus, Condurango 30C has anticancer potential in BaP-induced lung cancer of rats via tissue damage recovery and ROS-mediated programmed cell death.

This study was conducted by the questionnaires to 323 undergraduate students in fashion related departments. Questionnaires were designed to ask total 23 questions including possibility of halfway dropouts, establishment of goals, self-improvement, entrance motives, satisfaction ratings of academic subjects, job prospects and path planning, amelioration of ways to instruct, desires for the integrated lessons and intense academic courses, wishes of field project education carrying out tasks, desired lecturers, and others. Results in this research were summarized as follows. To begin with, it was appeared that respondents with possibility of halfway dropouts showed considerable percentage (25.4%) and the reasons left out were various including joining the army, the poor economic conditions in family, a major not corresponding with one's aptitude. Secondly, in the extent of establishing goals and improving oneself, there was the difference between people with possibility of halfway dropouts and people without that, and it was judged that the extent of establishing goals and improving oneself as good parameters could explain halfway omission. Thirdly, the ways to teach for getting classes interesting were to make instruction according to one's capabilities, to progress systematically, and to take lessons with specific goals. Fourth, many respondents answered to want the integrated lessons, intense academic courses, and field project education carrying out tasks. Fifth, an overwhelming majority of respondents hoped instructors with a outstanding ability in business. For improvement of the ways to instruct and the role of professors, it is suggested as follows. First, students are given intelligible lessons focused on fundamental subjects fitted to their levels and also need gradual intense academic courses classified by their way directions and interests. Second, creative and individualized teaching methods depending on the majors and levels are developed to help students have strong interest in schoolwork. Third, professors are constantly to learn practical techniques and skills related to industries in step with the education goals of college. Fourth, it is desirable to adopt instructors with practical business talents rather than theoretical capabilities.
