Purpose : This study was undertaken to evaluate the effects of the different administration duration of Epimedium Herb extract solution on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase. Methods : We used the 2-month-old mice and administered the extract solution of Epimedium Herb 0.3 ml/g/day for 30, 60, 90 and 120 days. The control group was administered the normal saline as the same way. We examined the number of total, motile and normal sperm from the cauda epididymis, the activities of sperm hyaluronidase. Also we observed changes of isolated testis before and after administration of Epimedium Herb extract solutions in the mice. And we compared the testicular tissue especially seminiferous tubules with the control and treated group by histochemical methods. Results : The significant differences were observed in the concentration of total sperm and normality of spermatozoa of the Epimedium Herb extract solution administered groups compared to the control group in 60, 90 and 120 days groups. The significant differences were observed the motility of the Epimedium Herb extract solution administered groups compared to the control group in 60 days group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Epimedium Herb extract solution administered groups compared to the control group, respectively. And the activity of hyaluronidase was significantly increased in the Epimedium Herb extract solution administered groups compared to the control group. Conclusion : This study shows that Epimedium Herb has the beneficial effect on the concentration, morphology and motility of sperm, the testicular tissues and the activities of sperm hyaluronidse in 60 days administration group. We can suggest that Epimedium Herb extract solution be useful for the treatment of male sexual dysfunction and infertility.

Nowadays according to the complexity of our daily life due to the development of industry and transportation various kinds of injuries happen. Since 1993 the death rate among 5-14 age children by injuries amount to about 57%. Furthermore, the injury of children can give a direct damage to their own family and it can also bring a serious loss to the country as well as the community where they live in accord with degree of an injury. From this reason, the importance of safety education has been increasing. In this study, it is aimed to clarify the effect of injury preventive behaviors on injury incidence of the 6th grade students in the elementary school. This study is accomplished by the survey sampled from 9 elementary schools in seoul, each of which belong to different district. The survey took for 15 days from the date of september 10th 1996 to september 25th 1996 and the results were as follows; 1. For demographic characteristic, sexual distribution was 48.7% of male students and 47.1% of female students. The required time from home to school was 10-19 minutes(51.8%), and the most way of their going to school is to walk(89.7%). Mothers who graduated from high school were 46.6% and 49.4% of fathers were above university graduated level. The most vocation of mothers was housewife as 56.7%. 2. The results of analysis on the injury rates, 75.8% of children experienced more than one injury and the most was play injury. With regards to sites where injuries happened, the room, the kitchen, and the living room in the house ranked first(38.3%) and then injuries at school such as on the playground, in the classroom, and on the stairs was 34.1%. 3. Considering the rate of injury incidence in accordance with demographic characteristics, male students experienced more injuries than female students(p〈0.05). For the way from home to school, children who went to school by bicycle experienced the most injuries and then on foot, by bus in order of which differences were statistically significant(p〈0.05). 4. From the comparison of parents' safety education practice and the injury incidence, the less often parents practice safety education, the more often children experience injuries(p〈0.05). 5. The results of analysis on the effect of injury preventive behaviors on accidents children who didn't act injury preventive behaviors experienced much more injuries than those who did injury preventive behaviors of which differences were statistically significant(p〈0.01). 6. From the results of analysis of factors effecting on the elementary school children's injuries, children without injury preventive behaviors had more effect on accidents than those who had injury preventive behaviors as odds ratio 2.06(p〈0.01), and the odds ratio of male students compared with female students was 1.47(p〈0.05).

Three studies were conducted to determine the effect of sex on pre- and post-weaning performance of pigs. These studies were conducted in response to observations that female pigs appear to grow faster than male pigs after weaning. In addition, female pigs have been found to grow faster than male pigs when supplied with supplemental milk before weaning. The aims of the present work were to further characterise the ontogeny of sex differences growth of nursing and growing pigs. In the first study, piglets sucking 32 sows were crossfostered to produce litters of 10 boars (n=9), 10 gilts (n=l 1) or 5 boars and 5 gilts (n=12). Liveweight of the sucking pigs was then measured weekly until weaning at 4 weeks of age. In the second study, 80 boars and 80 gilts were weaned at 26 days of age and growth performance measured until 21 days post-weaning. In the third experiment, 40 boars and 40 gilts were weaned into groups of 5 pigs at either 17 or 25 days of age and pigs were weighed until they were approximately 90 kg liveweight. All-boar litters grew more slowly than the all-gilt and mixed litters such that by 14 days of age the all-boar litters were 10% lighter than the all-gilt or mixed litters (39 vs. 43.8 kg, p=0.050). The proportional difference in litter weight appeared to be maintained at 21 days of age (53.9 vs. 59.4 kg, p=0.063) but was diminished by 28 days of age (66.5 vs. 70.8 kg, p=0.28). In the second study, gilts grew more quickly than boars over the first 7 and 21 days post-weaning and as a consequence were 10% heavier than boars at 21 days after weaning (13.7 vs 12.48 kg, p=0.001). In the third study, gilts grew more quickly than boars in the immediate 7 days post-weaning (40 vs. 5 g/day, p=0.014) whereas from 7 until 35 days post-weaning there was no significant difference in growth rate (381 vs. 360 g/day, p=0.19). Gilts also grew more quickly than boars over the 14 days after being moved into the grower (631 vs. 570 g/day, p=0.013) and finisher (749 vs. 688 g/day, p=0.038) sheds. However, these differences were not maintained over the entire period in each shed. These data support the hypotheses that gilts handle the stresses of weaning and other transitions better than boars.

Objective : This study examined the socioeconomic differentials for the health and health related behaviors among South Korean middle school students. Methods : A nationwide cross-sectional interview survey of 3,449 middle school second-grade students and their parents was conducted using a stratified multi-stage cluster sampling method. The response rate was 93.3%. The socioeconomic position indicators were based on self-reported information from the students and their parents: parental education, father's occupational class, monthly family income, out-of-pocket expenditure for education, housing ownership, educational expectations, educational performance and the perceived economic hardships. The outcome variables that were measured were also based on the self-reported information from the students. The health measures included self-rated health conditions, psychological or mental problems, the feelings of loneliness at school, the overall satisfaction of life and the perceived level of stress. The health related behaviors included were smoking, alcohol drinking, sexual intercourse, violence, bullying and verbal and physical abuse by parents. Results : Socioeconomic differences for the health and health related behaviors were found among the eighth grade boys and girls of South Korea. However, the pattern varied with gender, the socioeconomic position indicators and the outcome measures. The prevalence rates of the overall dissatisfaction with life for both genders differed according to most of the eight socioeconomic position indicators. All the health measures were significantly different according to the perceived economic hardship. However, the socioeconomic differences in the self-rated health conditions and the psychosocial or mental problems were not clear. The students having higher socioeconomic position tended to be a perpetrator of bullying while those students with lower socioeconomic position were more likely to be a victim. Conclusions : The perceived economic hardships predicted the health status among the eighth graders of South Korea. The overall satisfaction of life was associated with the socioeconomic position indicators. Further research efforts are needed to explore the mechanisms on how and why the socioeconomic position affects the health and health related behaviors in this age group.

The culture includes every possible objective forms created by humans and their shared aspects of ideas, feelings, and behaviors, beliefs and etc. The dress and its ornaments are part of the culture that expresses the relationships in objective ways and in formless immaterial ways. The school uniform represents significant meanings to the students in their school years, and it is the way of expressing their individuality and full filling their needs for self-presentation. Therefore, understanding and analyzing youth culture means understanding students' school uniform along with fast changing twenty first century civilization. Korea and Japan are very close nations to each other. Both Korean and Japanese girls' school uniform style were adopted western clothing style and went through many changes based on cultural differences between two countries. They are affected by different peculiarities between two nations and youth cultures from different cities. Therefore, this research is on analyzing how different visual values of girl's high school uniforms in Seoul and Tokyo and understanding youth cultures through macro-analysis. The youth cultures in Korea and Japan are mostly similar but there is special development on animation in Japan and possibly can find many styles of girl's high school uniform. Both nations are varying to be opened to sexual culture of adolescents but Japan is more uninhibited than Korea. In Japan, sailor-uniform can be found in fetish way in public culture. On one hand, because of most private girl's high schools in Tokyo takes an entrance examination, top-ranking students are very proud of their school uniforms and even students from other public high schools get private high school uniforms to attend school festival. This analysis showed that private girl's high school uniform in Seoul appealed as slim fitted silhouette which is close to modem woman's suit style while in Tokyo appealed as boxy style matched with short pleated skirt or sailor-uniform style. Comparing that to school uniform photos taken on the street, we can find that alikeness or more extreme styles as examples. These are influenced by different youth cultures in Seoul and Tokyo and cultural differences stands for different aesthetic norm being accepted or rejected.

배경 및 목적 : 신체화 장애의 병인은 잘 알려져 있지 않으나 우울증, 감정표현불능증, 심리적 문제에 대한 미숙한 방어기제로 다양한 신체 증상으로의 신체화, 그리고 사회문화적 영향 등의 결과로 신체화가 생긴다는 이론 등이 있어 왔으나, 이런 이론들만으로 신체화의 기전을 완전히 설명할 수 없으며, 해리의 기전이 일부 작용하는 것으로 최근 국외의 연구들에서 알려지고 있다. 본 연구에서는 신체화 장애를 나타내는 환자에서 실제로 어느 정도 해리가 정신병리적으로 작용하는지를 조사해 보고자 하였다. 또한, 신체화 장애 환자에서의 성적, 신체적 학대 또는 신체 증상과 우울증과의 관련성도 조사해 보고자 하였다. 대상 및 방법 : 다수의 신체 증상을 호소하는 52명의 환자 중에서 DSM-IV의 선체화 장애의 진단 범주를 만족하는 25 명의 환자군과 부산 일 지역에 거주하는 51 명의 일반인 대조군을 대상으로 하였다. 양 군에게 한국어판 해리경험척도(Dissociative Experiences Scale-Korean Version)와 해리장애면담양식(Dissociative Disorders Interview Schedule ; 이하 DDIS)을 시행하였다. DDIS의 문항 중에 신체화 장애 설문지는 46개의 문항으로 구성되어 있으며 이를 기준으로 신체화 장애 환자를 선별하였다. DDIS의 학대에 대한 문항 중에서 본 연구에서는 신체적 혹은 성적 학대 여부만을 선택하였다. 양 군간에 연령, 성별, 결혼 상태, 종교 유무 및 교육 연한 등의 사회인구학적 특성에서는 유의한 차이가 없었다. 결과 : 신체화 장애 환자군이 일반 대상군에 비해 DES-K 총점에서 유의하게 높게 나타났다. 한국인의 신체화 장애 환자군에서도 일반 대상군에 비해 해리장애의 유병율이 높을 것으로 추정되었다. 신체화 장애 환자군이 일반 대상군에 비해 소아기 학대의 과거 병력이 높게 나타났다. 신체화 장애 환자군에서 신체화 장애와는 인과 관계가 없는 것으로 추정되는 주요 우울 장애의 동반 유병율이 높았다. 결론 : 신체화장애 환자는 일반인에 비해 해리 경향이 높고, 소아기 학대의 경험이 비교적 많으며, 또한 동반된 우울 장애의 유병율이 높게 나타났다. 한국인의 신체화 장애에서도 해리 경향은 이 장애에 흔히 동반되는 증상이며, 신체 증상의 발생 기전으로 작용하는 것으로 추정되었다. 신체화 장애 환자에서 소아기학대의 병력을 알아 볼 필요가 있으며, 해리장애의 이중 진단도 고려해 볼 필요가 있다고 생각되었다.
