Purpose: This study aimed to obtain data for the examination and prescription of clinical trials. Subjects were divided into binocular vision types by the Howell card phoria method. We compared calculated accommodative convergence/accommodation (AC/A) ratio and gradient AC/A ratio by using deviations according to fixation distance and lens additions. Methods: The subjects in this study were 117 undergraduate students (84 males and 31 females) with an average age of 20.89±1.83 years. The binocular vision types were separated into seven groups by Morgan’s norm according to the Howell card phoria method and measured calculated AC/A ratio and gradient AC/A ratio. Results: In terms of phoria changes according to fixation distances and additions, as the fixation distance neared, the groups of convergence insufficiency, basic exophoria, orthophoria and divergence insufficiency moved towards exodeviation but the groups of divergence excess, convergence excess, and basic esophoria moved towards esodeviation. The calculated AC/A ratio with accommodative convergence and proximal convergence appeared larger than the gradient AC/A ratio with only accommodative convergence. The differences of calculated AC/A ratio and gradient AC/A ratio showed statistically significant differences in the divergence excess (1 m p=0.049, 50 cm p=0.047, 33 cm p=0.034, 25 cm p=0.031), basic exophoria (50 cm p=0.000, 33 cm p=0.006, 25 cm p=0.037), orthophoria (50 cm. p=0.019, 33 cm p=0.021), convergence excessive (50 cm p=0.016, 33 cm p=0.030), basic esophoria (50 cm. p=0.029, 33 cm p=0.024). Conclusions: In all binocular vision types, the calculated AC/A ratios were larger than gradient AC/A ratios. Therefore, when binocular abnormality is performed during a clinical examination, it is necessary to apply the calculated AC/A ratios and gradient AC/A ratios together.

N/A Objectives : This study was conducted to develop the oriental medicines which have hair growing effects and evaluate the efficacy of the mixture extract of Polygoni multiflori Radix, Angelicae gigantis Radix and Lycii Fructus in the rat dorsal hair growth. Methods : The oriental medicine extract was administered orally and enzyme(GOT, GPT, ALP and y -GTP) activities, lipid(total cholesterol and total lipid) contents and hormone(testosterone and dihydrotestosterone) contents were measured to see whether or not the extract has hair growth effect and the hepatotoxcitiy in rats. Results : The results of animal experiment that was investigated to search the effect of the oriental medicine extract in androgenetic alopecia are as follow : 1. The liver damage with adminstration of oriental medicine extract was investigated. As results, there was no significant differences between control and the rest two, propecia and oriental medicine extract, in serum GOT, GPT, ALP and y-GTP`s activities and total cholesterol and total lipid contents. Therefore, this demonstrated that the oriental medicine extract didn`t induce the liver damage. 2. Total (T+DHT) contents of serum and skin were measured to know the effects of the oriental medicine extract on the hair growth in rats. Total(T+DHT) content was increased significantly in propecia and the oriental medicine extract in comparison with control group. Moreover, the oriental medicine extract showed higher serum total(T+DHT) content than that of propecia. 3. Serum and Skin DHT contents were examined. Propecia and the oriental medicine extract decreased serum and skin DHT contents significantly compared with control group. The extent that propecia and the oriental medicine extract decrease DHT content was the same and this demonstrate that the oriental medicine extract has the same effect of hair growth as that of propecia. Conclusion : The mixture extract of oriental medicines has hair growth effect by decreasing serum and skin DHT contents and doesn`t have any liver damage when it was administered orally.

대추 메탄올 추출액이 B(a)P에 의해 유도된 간손상에 미치는 영향을 알아보기 위하여 흰쥐에게 1주일간 대추 추출액을 1일 1회 경구투여하고 B(a)P을 대추 메탄올 추출액을 투여한 마지막 날에 1회 복강주사하여 효소 활성도와 지질 함량 변화를 측정하고 MTT assay를 수행한 결과는 다음과 같다. in vitro 실험에서 B(a)P은 간세포에 대해 현저한 세포독성을 나타내었으며 대추 메탄올 추출액은 이러한 세포독성을 정상수준으로 유의성 있게 회복시켰다. 또한 in vivo 실험에서도 B(a)P의 투여는 효소 활성도와 지질 함량을 유의성 있게 상승시켰고 대추 추출액은 이러한 상승을 유의성 있게 감소시켰다. 따라서 대추 메탄올 추출액은 in vitro와 in vivo에서 공히 B(a)P으로 인한 간손상에 뚜렷한 보 호효과를 나타내었는데 이는 대추 추출액이 간의 저항력 및 간세포 기능을 유지시키므로써 보간작용을 한 것으로 사료된다. The protective effect of jujube methanol extract on benzo(a)pyrene (B(a)P)-induced liver injury was studied in rats in vitro and in vivo. Jujube methanol extract significantly recovered the enzyme activities (GOT, GPT, LDH and ALP) and lipid contents(total cholesterol, triglyceride and HDL-cholesterol) changed by B(a)P to normal levels in vivo. in vitro experiment jujube methanol extract didn't stimulate hepatocyte proliferation but significantly recovered the enzyme activities(GOT, GPT and LDH) in comparison to group Ⅱ administered B(a)P only. It was suggested that jujube methanol extract have a protective effect on liver injury by B(a)P.

This study considers the comfort of residents and energy use in buildings at the same time to improve the Green Building law system. Based on solar radiation control, the following conclusions were drawn by conducting experiments in apartment buildings using equipment. Indoor temperature has a direct effect on comfort. Rather than frequent control of air-conditioners, it is necessary to control Solar Radiation Control that can maintain room temperature. In the future, further studies are needed on changes in the amount of solar radiation inflows over time. The results of this study can be used as a basis for various studies for application within the Green Building law.
