매실의 野生酵母를 발효 실험을 통하여 酵母의 同定, 酒精, Fusel oil 및 香氣 成分을 分析한 結果는 다음과 같다. 매실에서 발견된 野生酵母는 Saccharomyce cervisiaeSP. 5종 Pichti속 3종. Torulopsis 2종을 同定하였다. 酒精 生成力은 일발연 1호가 16%였으며 野生 酵母Ⅰ,Ⅱ.Ⅲ,Ⅳ는 각각 15.2%, 14.1%, 7.64% 및 13.5%였다. Fusel oil 生命力은 일발연 1호가 2.7%, 396호가 2.6%였으며 野生 酵母 Ⅰ,Ⅱ,Ⅲ,Ⅳ는 각각 0.5%, 0.3%, 0.3% 및 0.5%로 나타 香氣 成分은 일반연1호, 396호, 野生 酵母Ⅰ은 비슷하였으며 野生 酵母Ⅱ, Ⅲ, Ⅳ는 香氣 成分이 많은 것으로 나타났다. This study was conducted to evaluate the alcohols and flavors through fermentational using the wild yeast isolated in Mume(prunus mume s.e.t.z.)and the wild yeasts were identified, concurrently. The alcohols and flavors were analyzed by chromatography. 5 species(Sacch,cerevisiae sp.), 3 species(Pichia genus)and 2 spcecies(Torulopsis sp.)were identified. In the alcohol yielding ability test of yeasts, the yielding ability was 16% in Sacch cerevisiae, and 15.2%, 14.1%, 7.6%and 13.5% in the wild yeasts(#1,2,3,4), respectively, while in the fusel, the percentage of fusel oil was 2.7% in Sacch. cerevisiae, 2.6% in sacch. formosensis, and 0.5%, 0.3%, 0.3%and 0.8% in the wild yeasts(#1,2,3,4,)respectively. The amount of flavors made by yeasts such as Sacch cervisiae, Sacch. formosensis and wild yeast #1 was similar in each case but that of the wild yearst #2,3,4 was much more than above 3 species yeasts.

A successful therapy of community-acquired pneumonia requires appropriate empirical antimicrobial therapy. Etiology and antimicrobial susceptibility of major pathogens of pneumonia can differ by country. Therefore, an ideal treatment guideline of community-acquired pneumonia should be based on the studies performed in each country. We developed a treatment guideline for community-acquired pneumonia in immunocompetent adults in Korea. This guideline was developed by the joint committee of the Korean Society for Chemotherapy, the Korean Society of Infectious Diseases, and the Korean Academy of Tuberculosis and Respiratory diseases.

Quercus variabilis is one of the most important tree species in both utilization of forest resources and management of forest ecosystem in Korea. To obtain the basic information for the establishment of breeding strategy and efficient management of genetic resources, five populations of Q. variabilis from 89 selected plus trees were studied using POPGENE and AMOVA analysis based on DNA markers focussing on the genetic diversity and variation among populations. The overall polymorphic amplicons were 78.6% and levels of genetic diversity within 5 populations were similar each other (Shannon's Index : 0.289∼0.423 [mean 0.366]). The values of total genetic diversity (H_t) and average gene diversity within population (H_S) were 0.265 and 0.239, respectively. The degree of genetic differentiation (G_st : 0.098) was relatively high compared with those of other tree species. Based on the cluster analysis of UPGMA, genetic relationships among 5 populations were not coincided with the pattern of geographic distribution.
국내 발전소별 바텀애시를 잔골재 대체재로 사용한 모르터의 특성에 대한 실험적 연구

With the advance in industrial development and modern living comfort, the demand for electricity throughout the country is ever increasing. Also the annual consumption of coal by coal-fired power plants is increasing. The amount of ash produced in 2000 is estimated to be about 4.5 million tons. The disposal of this huge amount of ash introduces serious environmental problems. Fly ash among the ash produced is used in building industries as a substitute to cement in concrete and the concrete thus produced is said to be lighter and stronger. But bottom ash among the ash produced is not used because of its poor properties. But encouraging the use of bottom ash as a construction material is a sensible method of utilization as it avoids the problems and costs associated with disposal and provides an alternative aggregate source. This study is aimed at using bottom ash as an alternative fine aggregate source to provide a solution to disposal and insufficient fine aggregate for the production of concrete. So properties of bottom ash produced in power plants were estimated due to the difference of bottom ash produced in each plant. And mortar strength was estimated as basic data to use bottom ash in building industries.

Both placental form (GST-Pi) and basic form (GST-L) of glutathione S-transferase were studied in the epithelium of normal, tumor and tumor like lesions of female genital system. The results obtained were as follows : 1. Staining reaction of GST-Pi were moderate in normal cytotrophoblasts, mild in syncytiotrophoblasts, strong in corpus luteum, moderate to strong in salpingeal mucosa and in proliferative glands, moderate in secretory glands of indometrium and moderate in superficial squamous epithelium of cervix 2. Staining reaction of GST-L were mild in cytotrophoblasts and in syncytiotrophoblasts, of chorionic villi in corpus luteum, negative in salpingeal mucosa, very weak in proliferative glands, mild in secretory, glands of endometrium and in superficial squamous epithelium of cervix. 3. Staining reaction of GST-L were mild in cytotrophoblast and syncytiotrophoblast of choriocarcinoma, moderate in cytotrophoblasts, mild in syncytiotrophoblasts of hydatidiform mole, negative in mucinous epithelium of cust adenoma, in hyperplastia and adenocarcinoma, and mild in adenocarcinoma of cervix. 4. Staining reaction of GST-L were very weak in cytotrophoblasts and syncytiotrophoblasts of choriocarcinoma and in hydatidiform mole, negative in mucinous epithelium of cust adenoma, very weak in serous eptiethlium, negative to mild in hyperplastic and adenocarcinoma, mild in squamous cell carcinoma and adenocarcinoma of cervix. Therefore, staining reaction and distribution of GST-Pi and L isoengumes were different in normal and neoplastic cell of trophoblasts, salpinx, endometrin and cervix

The aim of this study was to investigate the influence of inorganic pigments on the physical properties of cement mortar. For this purpose, the compressive stieugth and absorption test were carried out on cement mortar mixed with inorganic pigments by changing the proportion of cement mortar, water-cement ratio, and ratio of pigment. The result of this study can be summarized as follows: The compressive strength of colored mortar rapidly increased in red and yellow mortar, as the mix ratio of pigment increased. In case of green and black mortar, however, the compressive strength decreased as the mix ratio increased. In case of red and yellow mortar, the absorption of colored mortar increased as the mixing ratio increased, if the mean particle diameter of the pigment is small. In case of green and black mortar, the absorption ratio decreased as the mix ratio increased. After investigating the overall physical properties of colored mortar, it was confirmed that the proper mix ratio of pigment securing the properties of colored mortar was below 6% of the weight of the cement to be used.
