Chromosomes of gonadal tissues from Fasciola spp, Eurytrema pancreaticum and Calicophoron calicophorum occurred Korean cattle were egamined using modified air-drying method. To compare their phenotype with three different genotypes among Fasciola spp, the adult and egg si2e were measured since they have been known as important taxonomical characters. The results obtained were as followed; Cattle liver fluke, Fasciola spp were classified into three types based on their chromosomal complements such as individual with 2o chromosome(diploid), 30 chromosome(triploid) and 20/30 mosaic constitution(mixoploid). The propotions of appearance of three types were 40.00%, 54.29% and 5.71%, respectively. The frequency of three types in type I which was regarded as F gigantica were 58.82% for diploid, 35.29% for triploid and 5.88% for mixoploid, but in type II which was regarded as F hepatica were 72.2% for triploid, 22.22% for diploid and 5.56% for mixoploid. Egg length of triploid forms was significantly larger than that of diploid forms and egg size of mixoploid forms was similiar to that of triploid forms. Worm size of triploid forms was larger than that of diploid forms and was more similar to that of mixoploid forms, but the statistical data were not significant. Diploid chromosome consisted of one pair of metacentric chromosome(m), four pairs of submetacentric chromosomes(sm), five pairs of subtelocentric chromosomes(st), while triploid chromosome consisted of one pair of metacentric chromosome, seven pairs of submetacen.tric chromosomes, one pair of subtelocentric chromosome and telocentric chromosome(t), respectively. In mixoploid chromosome, constitution of the chromosomes of diploid or triploid cell was consistent with that of diploid or triploid. Chromosomes of gonadal tissues from pancreatic fluke, Eurytrema pancreaticum consisted of 13 pairs of homologs(2n=26, n=13). The mitotic and meiotic divisions were observed frequently. In the mitotic metaphase, Karyotype consisted of five pairs of metacentric chromosomes, four pairs of submetacentric chromosomes, three pairs of subtelocentric chromosomes and one pair of telocentric chromosome. Chromosomes of gonadal tissues from stomach fluke, Calicvphoron calicophorum consisted of 9 pairs of homologs(2n=18, n=9). The meiotic divisions was frequently observed, but mitotic divisions was rare. In the mitotic metaphase, Karyotype consisted of two pairs of metacentric chromosomes, three pairs of submetacentric chromosomes and four pairs of subtelocentric chromosomes. Karyotype of Calicophoron calicophorum differed from that of Japanese C calicophorum which was similar to that of Paramphistomum cervi of Korean cattle. Though that of Calicophoron calicophorum of Korean cattle was similar to that of Paramphistomum explanatum of Korean cattle, that have been recognized to be a different species of fluke.

The exercise of police power for danger prevention gives top priority to the prevention of injury occurrence. However, the controversy over the concept of danger has hitherto focused on the limit establishment, namely which scope is to be a target of prevention in the danger prevention area of the Police Law. After all, the police's duty for maintaining public peace and order is forced to be peformed through individual measures for danger prevention, and the preventive police action, which aims at the prevention of danger against the protection interest in the Police Law, can be performed on the premise of a precise understanding of danger in order to carry out a legitimate preventive police action. In addition, it examines the legal meaning in each constitution element by dividing the minimum common components of danger into loss, sufficient probability and time accessibility, and the interpretation problem of danger as uncertainty concept.

In modern society, the enterprises or the public organization have devised consistent means and methods with keen competition in high intelligence, high specialization and high competition for surviving in the struggle for existence. In the rapidly changing modern society like that, guard services are not free any more in the simple business. It will be survived only with consistent self-development and various abilities. Recently, it is on a trend that the enterprise including venture business requires the man of ability having many-sided thought, knowledge and capacity. That is, the era of a man with multi-function has come. The guards engaged in their present posts have to make efforts self-development consistently. And they have to work for self-development with theoretical knowledge acquirement about the expert knowledge escaping from simple function and business. The constitution including universities that train the guard should not adjust to the demand of quantitative manpower required in the enterprise organization with the training of the guard with simple functions only. It needs settlement as a curriculum with technology like ideology and knowledge breaking from short curriculum centered on function only in order to come to stay the recognition about guard services as expert services that the industrial society requires. The education centered on simple function should be replaced in the use of a high school, private academy and special guard institution. In addition, it requires a quality as the auxiliary, division, decision-making and spokesman according to the business role. Also, it requires the martial arts capacity, the communicative capacity, the sports or reports capacity, the guard driving capacity, the policy and assistant capacity and the information and analysis capacity, etc in individual. Lastly, it need each guard's change of cognition most of all. As part of the guard's adaptive plan according to the social change, it was enumerated like the mentioned above. It is important for the guard to prepare for the change of era and to build up quality and capacity before anything else.

The Sasang constitutional medicine classifies the mankind into four constitutional types according to the individual psychological and physical traits. Differences in the Sasang constitutional medicine may be explained by the genetic factors. In order to determine the association of Sasang constitutional classification and interleukin-1 receptor antagonist (IL-1Ra) in genetic susceptibility to ischemic stroke, we classified the four constitutional types in ischemic stroke patients (n = 125) and the healthy control subjects (n = 107), and genotyped for IL-1Ra polymorphism by polymerase chain reaction (PCR) methods. The distribution of the $IL1RN^*1/IL1RN^*2$ genotype in the ischemic stroke patients was significantly different from the healthy controls (OR = 6.09; P =0.0134). And the prevalence of $IL1RN^*1/IL1RN^*2$ genotype was increased in Taeum-in ischemic stroke patients, as compared to Taeum-in healthy controls (OR = 14.71; P = 0.0144). These results suggest that $IL1RN^*1/IL1RN^*2$ genotype in Taeum-in might be associated with the increasing risk for ischemic stroke. Furthermore, this relationship could provide the basis for a new approach in the investigation of the etiology of ischemic stroke.

he current VaR model based on the J.P. Morgan's RiskMetrics structurally can not reflect the future economic situation. In this study, we propose a One-factor model resulting from the Wiener stochastic process decomposed into a systematic risk factor and an idiosyncratic risk factor. Therefore, we are able to perform a preemptive risk management by means of reflecting the predicted common risk factors in the model. Stocks in the portfolio are satisfied with the independence to each other because the common factors are fixed by the predicted value. Therefore, we can easily determine the investment in each stock to minimize the variance of the portfolio. In addition, the portfolio VaR is decomposed into the sum of the individual VaR. So we can effectively implement the constitution of the portfolio to meet the target maximum losses.

Glutathione S-transferase polymorphisms (GST) were examined in 98 cases with cerebrovascular disease (CVD) to test the hypothesis that GST polymorphisms confer a risk to an individual to develop CVD. Tobacco smoke is a major cause of both cancer and vascular disease. We therefore were stratified the subjects with CVD for smoking status, and then examined whether polymorphisms in this detoxification enzyme gene, GST, influence risk of CVD. Neither GSTM1 nor GSTT1 genotypes in the CVD group was significantly different from the control group (n=230), even in smokers. We attempted the combined analyses for GSTM1 and GSTT1 genotypes in CVD for smoking status. No significant association observed between the combined genotypes and CVD. We also classified the subjects and control group into four types according to Sasang Constitutional Medicine, Korean Traditional Oriental Medicine, and investigated the association among GST genotypes, CVD, and Sasang constitutional classification. Our observations do not confirm the effect of the GSTM1 and GSTT1 genotypes as a risk factor for CVD, even in smokers. Furthermore, we first attempted to evaluate the efficacy of Sasang Constitutional Medicine, and to find an association with CVD.

The purpose of this study was to investigate the status of recognition and intake of Saeng shik among housewives in Seoul, Busan, Daegu, Kwangju and Daejeon during February, 2002. Saeng shik is an uncooked freeze dried powdered food made from grains and vegetables. We interviewed 800 housewives, aged 30 to 49 years, living in urban areas. The survey was conducted using individual interviews on demographic characteristcs, status of recognition of Saeng shik, and the intake of Saeng shik. The data was analyzed using a SPSS program. The results were summarized as follows: Forty percentage of the subjects were well acquainted with Saeng shik. More than 60% of the subjects understood that Saeng shik is ‘the thing of grains and vegetables in the form of freeze-dried powder without heating process’. Saeng shik was taken by 16.9% of subjects. There was a significant regional and economic level difference in Saeng shik intake (p<0.05). Among the reasons given for Saeng shik intake, meal substitution ranked the highest. Other reasons were prevention of adult diseases, or it being a low calorie food. The survey questioned which the subjects considered before buying Saeng shik, taste, effect, constitution, sanitation and safety, satiety. ‘Taste’ ranked the highest. Among the subject who had experienced taking Saeng shik, 35.6% answered that they would continue taking Saeng shit. The reasons given for stopping taking Saeng shik included its high cost and taste. The subjects recognized it not only as a meal substitute, but also as a nutrient supplement. Based on these results on urban housewives' status of recognition of Saeng shik and their intake of it, more research is needed to improve Saeng shik.
