This study was undertaken the biochemical characteristics, serotyping and antibiotics susceptibility to 79 strans of Escherichia coli isolated from patient from march in 1993 to December in 1993. Of 79 isolates, thirty one isolates(39.2%) were idenfied by pathogenic E. coli immune sera producted by Denka Seiken. Among them, 9 isolates(11.4%) were 06, followed by 015 and 044(4 isolates, 12.9%), respectively. 018, 0114, 0119, 0125, 0146, 0153 and 0164 were identified 1 isolate(3.2%), repectively. Resistance rate of E. coli isolated from patients against 12 antibiotics were 86.1%(68 isolates). Of them, resistance rate against TC was 68.3%(54 isolates), AM 64.4%(51 isolates), CB 62.0%(49 isolates), NN and NA 8.9%(7 isolates) and PB 1.3%(1 isolate), respectively. Of 68 resistant isolates, 59 isolates(86.8%) were resistant to more than 2 drug, followed by 2 drugs-resistance pattern01 isolates, 16.2%), 3 drug and 6 drig resistance pattern(9 isolates, 13.2%). Of multipleresistance pattern, AM-CB-SM and AM-CB-SM-TE pattern were most frequent(5 isolates, 7.4%, respectively) and more than 10 drugs resistance pattern was 1 isolate. Of 68 resistant isolates, 42(61.8%) were transferred their resistance to recipient cell (E. coli ML1410Na^(r)), Of them, the most frequently multiple transferred drugs was 2 drugs(40.5%, 17isolates) and the most frequently multiple transferred pattren was AM-CB(23.8%. 10 isolates).

In this study, we measured the activity of the erythrocyte pyrimidin 5'-nuclectidase(P5N) and urinary N-acetyl-β-D-glucosaminidase(NAG) from 154 workers exposed to lead and 43 workers not exposed. We analyzed the correlation of the P5N activity and NAG activity with other biololgical exposure indices of lead such as blood lead(PbB) and zinc protoporphyrin(ZPP). The measurement was performed by using high performance liquid chromatography(HPLC), spectrophotometer and atomic absorption spectrophotometer. The results are as follows : 1. The mean value of P5N activity for workers exposed to lead was 9.50±3.13 μmol uridine/hr/g Hb and 11.60±2.2 μmol uridine/hr/g Hb for workers not exposed. The P5N activity showed a normal distribution, but the other indices of lead showed logarithmic normal distributions. 2. The P5N activity and ZPP were decreased as PbB was increased. But the NAG activity had no correlation with changes of PbB. 3. The correlation coefficients of the P5N activity with other biological exposure indices of lead such as PbB, ZPP, NAG activity were -0.72, -0.55, and 0.05, respectively. We speculated that the P5N activity can be used as a reliable biological exposure index of lead but NAG activity can be used as a biological management index of lead.

The Purpose of this thesis is to suggest objective basic data for the super graphics in the urban landscape through the quantitative visual quality analysis. For this, the image structure of super graphics have been measured mainly by questionnaries and semantic differential scale method and analyzed by the method of factor analysis, means and multiple regression. Degree of visual preference have been measured mainly by questionnaries and likert attitude scale method and finally these data have been analyzed by using the stepwise method. The data were collected by presenting 12 super graphics photographs-4 each sample pictures from the 3 each selected districts representing typical urban landscape style(central business district, shopping district, apartment complex). Observer groups were categorized as professionals, students, the others. Result of this thesis can be summarized as fallows: 1. From all 12(3×4) sample super graphics, the value of each semantic differential scale among the observer groups were presented significant group difference, But no significant difference of the S.D.scale value were observed among central business district, shopping district and apartment complex super graphics. 2. For all experimental points, 4 types of fator have been observed. Factors covering the image of super graphics were found to be the evaluation, the intimacy, the potentiality and the tidiness. 3. Main factors of the super graphics image and factors indicating the group variations yielded high significance between areas. 4. The harmony with surrounding environment, the proper selection of super graphics subject yielded high values for all groups. Especially, the good color sense with building was the most important variable determining the degree of visual preference. 5. The urban C.B.D. super graphics obtained 5∼12 ranks of regional visual preference and the shopping district super graphics obtained 2∼11 ranks, and apartment complex super graphics obtained 1∼7 ranks.

In this study, we measured the urinary excretion of the hippuric acid after ingestion of several kinds of common soft drinks. The urinary hippuric acid has been known as a sensitive and specific biomarker of toluene exposure in workplace. But it has not been known exactly that drinking some kinds of soft drinks can increase urinary hippuric acid significantly even in usual dosage. These phenomena surely can invoke problems in interpretation of urinary hippuric acid at the regular health check up of the workers exposed to toluene. We recruited 140 healthy volunteers(medical school students) and surveyed their diet history, medication, smoking and drinking habit before experiment. The persons who had eaten some kinds of food or drinks which were including benzoic acid were excluded and the rest 122 were divided into 2 groups. The Experimental group(n=88) drank the soft drinks which contained benzoic acid, and the control group(n=34) drank the soft drinks which contained not. We checked the excretion of urinary hippuric acid in 1.5hr and 3hr after ingestion of the drinks in each group. The measurement of urinary hippuric acid was performed by using high performance liquid chromatography(HPLC). The results were as follows: 1. The mean age(year) was 23.3±1.4 in experimental group, and 23.5±2.4 in control group; the number of female was 13(14.8%) and 4(11.8%) in each group. 2. The geometric mean of urinary hippuric acid before drinking soft drinks was 0.24, and 0.21g/l in experimental and control group(p=0.426). In 1.5 hour after ingestion of the drinks, the geometric mean increased 1.14g/l in experimental group, and 0.17g/l in control group, which was significantly different after adjusting the urinary hippuric acid before drinking(p<0.01). By addition some other covariates(sex, smoking in amount) in the model, the result was not changed(p<0.01). In 3.0 hour after ingestion, the geometric mean was 0.32 and 0.16g/l in each group, even the difference was much smaller than that of 1.5 hour after drinking, which was statistically different after adjusting the urinary hippuric acid of before drinking(p<0.01), sex and smoking additionally(p<0.01). 3. The mean increasement of urinary hippuric acid after 1.5 hour(Diff 1) after ingestion was 0.83 in experimental group, which was significantly different from that of control group(-0.06, p<0.01). Diff 2(the increasement after 3.0 hour) was also different from each other(p<0.01). 4. We used 7 different kinds of soft drinks in experimental group. The increasement after drinking them was different from 0.57 to 1.05g/l after 1.5 hour, from -0.08 to 0.08g/l after 3.0 hour, but statistically not significant in each other(p=0.146, p=0.849 in sequence). We concluded that the soft drinks which contain benzoic acid could increase the urinary hippuric acid excretion significantly, even over 1.0g/l without toluene exposure. It seems to be needed that check the diet and drink(at least 3.0 hour before collect the urine) history is essential in interpretation of urinary hippuric acid concentration.

體育學에서의 範疇的 基本槪念에 의한 健康槪念 定立에 關한 硏究

This study has on object to re - thesis conception or definition of health on base of the physical education. For this I grafted the general conception of health on the categorical fundamental relation, and then I can take a conclusion as following. We have known that though a definition of physical education don't refer to health, it seeks after the wholesome human with physical, mental, social soundness in the inside. Until now, we have thought of the physical education as a tool for human education more than the essence of it. This study is for soloing these problems. That is to say, not any more, we must have eyesight the participational value theories get out of the peculiar value theory for the fully fanctioning person. For these things, I intended rearranging the definifion of health on base of logic of the categorical fundamental relation. Considering the existing definition of health, we have expressed it as a state being active easily in everyday life. I have known that we quote from the general definition of health even in the physical education. But, I come to feel that the health of different dimension must be established in physical education. Especially, we emphasize the health not in the level of leisure activities but in tough physical fitness. To perform mental activities in the mechanisal civilization and the information societh, I established these logics that we must have stronger physical fitness and mental will than in the past. We can use "I am healthy" when the physical and mental health consist of one from. I learned that when the monoism health was accomplished like these, it can be grafted physical category. That is to say, the health in the category of physical education must be different from the health mentioned in generally. To approach logically, I substitute the categorical fundamental relation. I learned that although we can divide it in various forms. these category took a boundary according to the understonding subject. We told that the categorical fundamental relation was related with the category of the existance and recognition. I understand that the former possible to divided from physical, Individual and society by the concept of existion, the latter possible divided from the subject condition and physical education's condition. After all, I place the focus on taking possess of superior to rank the physical education category because of including all the former and the latter. Therefore, I come into logic that the health in physical educational category must be set up the conception in more different location than the health level asking in these lower rank. Accordingly, from now, we must express more concrete, raising level that the definition of health is " the status leading physical health mental health and positive activities in society.
