The purpose of this study was to investigate the effect of aerobic training on body fat reduction. A total of 978 high school girls participated in this study (freshmen = 365 ; junior = 300 ; senior = 313). Within each grade, subjects who showed interest in physical exercise were selected and assigned into athletes group (20 for freshmen, 22 for junior, 29 for senior). The athletes group performed aerobic exercise for 100 minutes per day, 5 days a week with 70% of a subject's maximal heart rate. Each subject agreed to participate in this study when she was freshman. Thus, the length of exercise was dependent upon subject grade. That is, senior group was on the exercise program for two and half years, junior group for one and half years, and freshman group for six months. The results are as follows : 1. The mean value of % body fat for athletes group were 21.23 for freshman, 21.57 for junior, and 21.49 for senior. These values were a bit smaller when compared to those for non-athletes groups (26.32, 24.76, 23.65 for freshman, junior and senior, respectively). The comparison of % body fat between athletes and non-athletes group showed that the largest difference was showed in freshman group, followed by junior and senior groups. 2. For the athletes groups there was no significant difference in the mean value of % body fat between 3 grades. However, this was not the case for the non-athletes groups. There was a significant difference (p<001) among the 3 grades for the non-athletes groups, the freshman group being the largest, followed by junior and senior.

The purpose of this study is to compare the relationship between physical characteristics and % body fat, using the data from senior students at a girl's high school in 1993 (three years ago) and in 1996. The subjects of this study were high school girls in Seoul and were composed of 274 persons in 1993 and 284 in 1996. Their heights, weights and % body fat were measured. The results are as follows : Analyses of t-test revealed that there was a significant difference in height between two groups (p<.001), the mean value of height in 1996 being taller (2.26cm) than that in 1993. However, that of weight between two groups were almost identical. Although the mean value of two groups were similar, examination of the data showed that the maximum value of weight was quite different between the two groups (maximum value in 1993 being 92kg, as compared to 75.5kg in 1996). Also, the comparison of % body fat showed that the mean value in 1996 was larger than that in 1993 (23.66 vs. 22.59, p<.001). In summary, the results of this study suggest that we are not necessarily faced with the state to worry about side-effect by excessive fat accumulation as a result of high school girls' high calory intake. These results may be obtained by several kind of social causes but we must consider the student's stress of S.A.T, increase of class at school, and increasing energy consumption (decrease of S.D).

We have tried this experiments about measure of Human Body Fat from transverse body scans with Magnetic Resonance Image (0.5, Tesla). Images were created with a spin echo sequence using a repetition time 500msec, echo time 20msec, and 1cm length between 10mm cross sectional slices, and gained through a whole body. In vivo quantification of body fat with MRI was measured by two healthy Females Volunteers, each cut obtained with MRI was analyzed, traced papers on the view finder, and then digitized, at last calculated for the areas of Human Body Fat. The results of this study can be summarized as follows : Through the analyses of the Ratio of Human Body % Fat with MRI and Densitiometry, in Sub.1, Sub.2, MRI is estimated higher than Densitiometry, that is, Keys & Brozek's Method (1960) has the most remarkable score gaps, 6.94% (Sub.1), 6.21%(Sub.2). Chinn & Alleys Method (1960) has showed the score getting closest to MRI, 1.67% (Sub.1), 1.36%(Sub.2). And Siri's (1956) Brozek et al's (1963), which have been used as the most popular methods, make the difference of 4% approximately. As a result of this study, such as preceding studies about it Ratio of Human Body Composition with MRI has considered to be validated and trusted. Therefore, if we estimate for Ratio of Human Body Fat with much more subjects than this experiments we can suggest that the method with MRI is possible to develope low data adaptable in every field.

Primary squamous cell carcinoma of the endometrium is exceedingly rare. To be accepted as a primary carcinoma of the endometrium, the tumor must satisfy the criteria estalished by Fluhmann: There must be; 1) no coexisting endometrial adenocarcinoma, 2) no connection between the endometrial tumor and the squamous epithelium of the cervix, and 3) no squamous cell carcinoma of the cervix. We recently experienced a case of primary squamous cell carcinoma of the endometrium covering the submucosal leiomyoma in a 68-year-old female patient. On gross examination a submucosal leiomyoma covered by an irregular, dirty endometrium was found. On histologic examination the endometrium covering the leiomyoma revealed invasive, well differentiated squamous cell carcinoma. The uterine cervix showed no evidence of malignancy. In situ PCR using a probe for HPV 16/18 was negative in the carcinoma tissue.

The purpose of this study was to investigate whether the Bone Mineral Density (BMD) in a postmenopausal women has affected by a long-term swimming exercise. Swimming exercised 9 female and non-exercised 13 female were involved in this study. All of them were accepted by selection criteria through a questionnaire and personal interviews. Experimental group performed regularly swimming exercise while over a 8 year, but control group never taken part in any activities periodically. Bone densities were measured at Lumbar 2-4 and Femur's 3 sites (neck, ward's triangle, and trochanter) with DEXA method (Lunar DPX). There are no significant differences between two groups on the ages, body weights, heights, % fats, and menopausal durations. Bone densities on the neck and ward's triangle of Femur were 1.7% and 2.7% higher in the control group than in the swimming group, not significant between two groups. In the case of Femur trochanter and Lumbar 2-4 sites, swimming group however were nonsignificantly higher 2% and 5.3% than control group, respectively. In conclusion, it was recognized that a long-term swimming exercise may be ineffective to intensify local density, stiffly lowering in a postmenopausal women.
