This study was performed to see ground reaction force with different soccer studs with twelve players in Human Performance Laboratory(University of Calgary). Running speed was $4.0{\pm}0.2m/sec$ in straight running as well as vcut running. By using four different kinds of shoes; three different pairs of soccer shoes and one pair of jogging shoes, I reached a conclusion as following. In case of right and left ground reaction force, on the assumption that the positive magnitude of power is inversion and the negative is eversion, vcut running did not occur any inversion, which in the aspect of kinetic mechanics, thought to be decelerating movement. Because when eversion happens, it arises component force of power on heading direction about 8.6 times more than in the movement of straight running. In case of front and rear ground reaction, on the assumption that the positive magnitude of power is suspension power and the negative is propulsion, vcut movement is thought to be decelerating movement in the aspect of kinetic mechanics. Because on heading direction, this movement occurs component force of power about 1.8 times more suspension and 2.2 more propulsion than in the straight running movement. In case of vertical ground reaction, on the assumption that the first peak is the magnitude of power in impact and the second peak is the magnitude of power in active, we judged that the straight running movement performed more efficiently than the vcut movement in the aspect of kinetic mechanics. On the next study, I suppose that vcut running would make up an interesting subject in the aspect of improving kinetic performance ability.

Cryposporidium species have a wide host range. These coccidian parasites are found in close association with epithelial cells of many species of animals including mm. The gastrointestinal tract is most commonly affected in young ruminants and this parasite is thought to be considerable importance in calf diarrhea complex. Major outbreaks of cryptosporidiosis have been reported in calves, lambs, pigs and others including avian species. Cryptosporidiosis is transmitted by oocysts of Cryptosporidium species. Because cryptosporidiosis is common infection among animals, early literature considered it a zoonosis. Human infections contracted from calves, cats, and horse feces. However, the resrvoir host is longer considered the major source of infection. Mild cases of disease have been reported in farm workers. Immunosuppressed, very young and very old persons should avoid contact with this parasite because it may cause severe diarrhea. In order to detect of Crytosporidium sp infection from feces of cattle and pigs at Chonbuk Iksan and Kunsan area, sedimentation and modified acid fast stain were applied. The positive rate of Cryptosporidium sp infection from 1, 176 of cattle and 267 of pigs were 0.5 % and 16.8%, respectively. According to area in Iksan and Kunsan, the positive rates were 0.4% and 0.9% from cattle, and 18.9% and 12.1% from pigs, respectively. In cattle, positive detection rate was 0.6% in milking cows but not in Korean cattle.

Hair style is an expression of beauty for individuals and at the same time a clear social representation. It may be regarded as a means of knowing social recognition about social values and groups of the moment. The hair style clearly discriminated so-called the new woman, emerged during Chosun's modernization, and the old woman. Thus the purpose of this study is to examine changes in social recognition about the behavioral style of the new woman by relating them with women' s movements and with changes in female education policies. Results of the study can be described as follows. First, the new women in the 1920s were evaluated positive as those who were leading struggles against Japan and enlightenment campaigns. But between the 1920s and the 1930s, those women were thought to be negative in that they were appearance-oriented, extravagant and sticking themselves to reality. Second, how a variety of social figures recognized short-hair was determined here through reviewing the mass media of the 1920s. At that time, some men were positive about short-hair like feminists while others denied the convenience of the hair style in life and were negative about the new women's individualism and pursuance of luxurious appearance. Third, there were both positive and negative social recognitions about short-hair in the 1930s. which were supported by the mass media of that time.

Pseudomembranous colitis, thought to be uncommon in children, is a bacterial, toxin-mediated inflammatory process resulting in acute or chronic diarrhea and is characterized by colonic pseudomembranes. It is mediated by toxins produced by Clostridium difficile and is increasingly recognized in pediatric population. Diagnosis is based on positive culture of C. difficile in selective media and positive test of C. difficile toxin. Oral metronidazole or vancomycin are the main treatment options but avoidance of further antibiotics should also be encouraged where possible. We have experienced a case of pseudomembranous colitis in a 4-year-old female presented with septic shock and colitis. This case was diagnosed with positive test of C. difficile toxin B and confirmed by isolation of the organism on cultire in selective media. Symptoms have been ameliorated by discontinuation of antibiotics and administration of metronidazole and oral vancomycin, and ICU care.

The objective of this study was monitoring of genetically modified soybean by PCR and ELISA. We collected 60 soybean samples from the open markets located in Western Gyeongnam (Sacheon, Hamyang, Hadong, Sanchung, Uiryung, Geochang, and Hapcheon). A total of 60 soybeans was examined and 14 genetical modified soybean (GMS) were detected by PCR. The GMS rate of selling soybean in Uiryung, Hadong, Sacheon, and Hapcheon was 50.0%, 37.5%, 33.3% and 25%, respectively. The 7 of 14 GMSs were positive by ELISA and most of positive samples were below 3% GMS but 1 (Uiryung 1) of the positive samples was over the 3% which is maximum permit limit in Korea. These results mean that merchants of open market did not express for selling soybean mixed with GMS, so consumers did not recognize GMO. Therefore, we thought that education of GMO for merchant of open market need to recognize about GMO maximum permit limit.

This study was performed to know about the conformity tendencies of adolescent and adult groups based on lectures of the expert on the topic 'the cicada'. Characters of each lecture were 'he pure natural science', 'positiveness', 'negativeness' and 'neutrality,' and then attitude changes on the cicadas were investigated with a questionnaire. Consequently, half of the adolescent and adult groups thought of the cicadas' sounds as 'noise' through mass communications respectively. They had a neutral attitude, neither positive nor negative, on cicadas' sounds in the beginning. Attitudes of the people on the cicada, however, were changed positively only with a pure natural science lecture. In this case, the adolescent group was more prevalented by the lecture than the adult group. In other words, the positive-based lecture affected them positively, while the negative-based lecture affected them negatively. The conformity tendencies of adolescent groups participating in the positive-based lecture were substantial. In conclusion, as we can see from the so-called Kohlberg's 'stages of moral development', conformity tendencies of attitudes towards cicadas' sounds were generally much more prevalent in the adolescent group, compared with the adult group, even though there are some differences in subcategories.
