N/A Most authorities agree the higher incidence of gallstones among diabetic patient. Although many reports on gallstones or diabetes mellitus have been published, and actual correlation between gallstones and diabetes mellitus remains obscure. The purpose of this reports is to know the incidence of gallstone in diabetics and of diabetics in the patients with gallstone. Authors studied prospectively and clinically the diabetics in a group of 173 patients with gallstones and gallstone in a group of 98 diabetic patients who were admitted to Yonsei University Yong-Dong Hospital for the same period of April 1983 to May 1984. The results obtained are summarized as follow: The incidence of gallstone to general admission patients is 1.5% and the prevalence of diabetes mellitus to total in-patients is 0.8% The gallstone was found in 11.0% of diabetics and were diabetic 19.4% of patients with gallstones. The age of peak incidence of gallstones is 5th decade and female was more prevalent than male with the ratio of 1.37:1. The age of peak incidence of diabetes mellitus is 6 th decade and female is less prevalent with the ratio of 0.72:l.3, The most common characteristic finding of patients of gallstones with diabetes mellitus is symptomless(42.1%)4, There is no significant difference in serum levels of cholesterol and triglyceride between diabetic and non-diabetic groups or with and without gallstones. 5. Comparative study on location of stones revealed, 72.8% in gallbladder only, 12.7% in common bile duct only, 4. 6% in intrahepatic duct only, and remainders in multiple site. There is no significant difference in terms of location of stone between diabetic and nondiabetic group.

방향족 탄화수소인 tnmethylbenzene (TMB)은 그 사용량이 늘어갈 뿐 아니라 직업적으로 폭로되는 양도 증가하고 있으므로 생물학적 모니터링 및 흡수, 대사, 배설에 관한 연구가 중요시되고 있다. 일반적으로 TMB는 간의 산화효소에 의해 하나의 메틸기가 산화되고 이것은 glycine과 포합되어 배설되는 것으로알려져 있다. 본 연구에서는 1,2,4-TMB의 대사체를 합성하고, 모세관의 전기영동법으로 분석할 수 있는 방법을 개발하였다. 모세관 전기영동법으로 흰쥐의 뇨 중에서 1,2,4-TMB의 대사체인 3,4, 2,4, 2,5-dimethylbenzoic acid 및 3,4 2,4 2,5-dimethylhippuric acid를 분석하기 위하여 내경 75㎛, 총길이 35cm (검출기까지 29cm)인 용융실리카 모세관을 15℃로 유지하면서 양단에 10kV의 전압을 걸어주고, 전해질로는 15mM β-CD, 3% 2-프로판올을 포함하는 01m 인산완충액 (pH 7)을 사용하였으며, 검출신호는 UV 210nm와 254nm에서 동시에 모니터링하였다. 뇨 시료의 분석 결과 배설된 1,2,4-TMB의 대사체의 상대량은 3,4-이성질체가 56.&%, 2,4-이성질체가 30.5%, 2,5-이성질체가 12.8%였다. 이 방법은 노동자의 뇨 분석에도 적용될 수 있을 것으로 생각된다. The metabolites of 1,2,4-trimethylbenzene (TMB) were synthesized and determined by capillary electrophoresis (CE). The optimum conditions of CE for the separation and determination of 3,4-, 2,4-, 2,5-dimethylbenzoic acid and 3,4-, 2,4-, 2,5-dimethylhippuric acid from the rat wine were as following: the fused silica capillary(75μm i.d. X 36 cm length, 29 cm to detector) was used and kept at 15℃ The applied voltage was 10kV and compounds were detected at UV 210 nm and 254 nm. The running electrolyte was 0.1 M phosphate buffer (pH 7) contalI1ing 15 mM of β -CD and 3% of 2-propanol. The relative amount of the metabolite of 1,2.4-TMB in the rat urine was 56.7% of 3,4-isomer, 30.5% of 2,4-lsomer and 12.8% of 2,5-isomer. This method can be applied to the analysis of TMB-metabolites in human wine.

The aim of this paper is to derive the simple formulae which could express the position of the sun with only a function of time. Methods for determining the position of the sun by use of the existing analytic theories are discussed. The low-precision (errors within 1 minute of arc) simple formulae for the coordinates of the sun are derived by omitting higher order terms of the polynomial functions. The results may be widely used to the automatic solar setting devices with the aid of calculators or microcomputers.

This study is to evaluate the characteristics of submerged biofilter process as pretreatment of raw water and alternative advanced water treatment system(AAWTS) composed with bioflitration, post-ozonation and GAC for Nakdong River by comparison of existing advanced water treatment system(EAWS), composed with pre-ozonation, flocculation, sedimentation, sand filtration, post-ozonation and GAC. In the biofiltration process, the removal of turbidity, color, KMnO₄consumption, NH₃-N and UV254 reached 98%, 95%, 70%, 72%, 79% respectively. The stable removal efficiency was obtained by the direct biofiltration after coagulant injection thought the influent was a muddy and highly polluted. The removal efficiency of the alternative advanced water treatment(AAWTS) using biofiltration process for turbidity, color, KMnO₄consumption, NH₃-N and UV254 was reached 98.5%, 98%, 82%, 90%, 92% respectively. It is equivalent to the removal efficiency of existing advanced water treatment system(EAWTS) though the demanded area and coagulant of the alternative advanced water treatment system using biofiltration process was decreased about 60% and 70% respectively.

우리나라 재래종 벼 197품종과 생태형이 다른 자포니카 7품종, 인디카 3품종 및 통일형 5품종의 벼를 공시하여 각 품종의 이삭 특성을 밝히고 이들 형질간의 상관관계를 검토하였으며 특성에 따른 이삭형태의 분류를 실시하였다. 1. 재래종 벼 품종의 이삭 길이는 22.4 .05㎝, 현미의 천립중은 21.7 .35g로 자포니카와 비교하여 천립중은 같았으나 이삭 길이는 1.6㎝ 더 길었다. 2. 재래종 벼 품종의 1차지경 착생립수와 비율은 67.5 1.9립과 43.7 .14%이었고, 2차지경 착생립수와 비율은 91.2 0.7립과 56.3 .14%이었으며, 총립수는 158.1 5.8립으로 자포니카보다 44립 정도 더 많았다. 3. 재래종 벼 품종 현미의 장폭비는 1.70 .19로 자포니카와 유사하였으며 장립종도 몇 품종 존재하였다. 4. 1차지경 평균착생립수 각 절위별 2차지경수 및 2차지경 평균착생립수에 의한 재래종 벼 품종의 이삭형태를 분류한 결과 2차지경립 착생 하위우세형인 Ⅰ형에 2%, Ⅱ형에 10.7%, 중위우세형인 Ⅲ형에 67.5%, Ⅳ형에 18.3% 및 상위우세형인 Ⅴ형에 1.5%가 분포하였으며, 특히 1차지경 평균착생립수 5.1-5.5개의 Ⅲ형에 가장 많이 분포하였다. 5. 각 형질간의 상관관계에서 총립수와 2차지경 착생립수(0.921), 착립밀도와 평균 2차지경수(0.635)간에는 고도로 유의한 정의 상관이 인정되었다. The traits related to panicle are very important in improving the grain yield in cereals including rice. Characterization of panicle traits was conducted using 197 rice varieties of Korean landrace, 7 cultivars of Japonica, 3 cultivars of Indica and 5 cultivars of Tongil type to classify panicle types by distribution patterns of grains on panicle. In Korean landrace, average length of panicle and 1000-grains' weight of brown rice was 22.4±2.05㎝ and 21.7±2.35 g, respectively. Compare with Japonica. Iandrace was similar in 1000 grains' weight, but with a more longer panicle. Higher number of grains on each panicle (44 grains), was observed in landrace relative to the Japonica of rice. Panicle type was classified into five groups according to the number of grains on the primary rachis-branch, number of grain on the secondary rachis-branch and number of the secondary rachis-branches. According to panicle type based on distribution of grains, landrace was classified into five types. Most of the landrace grouped into panicle type Ⅲ, which is characterized as having many grains on the secondary rachis-branch in the middle position of panicle. Especially, frequency of panicle type Ⅲ which have 5.1-5.5 grains on the primary rachis-branch was higher than any other panicle type. In the case of correlation coefficient among panicle traits, highly positive significant correlations were observed in number of grain per panicle versus number of grains on the secondary rachis-branch(0.921) and in density of grain per unit panicle length versus number of secondary rachis-branch(0.635)

Cochlea is well known to have the ability to analyze a wide frequency and this ability seems to be caused to the Basilar Membrane(BM) configuration. However, the relationship between the Cochlea frequency-position map is not clear. In this paper, the three-dimensional BM model was made using the Finite Element Method. Then, an attempt was made to examine the influence of the BM configuration on the Cochlea frequency-position map.
