큰 규모의 프로그램을 작성할때 겪는 함수들간의 상관 관계는 프로그램의 크기가 커질수록 이해하기가 힘들어진다. 이 경우에 프로그램을 트리 형태를 이용하여 함수가 호출되는 관계로서 표현하면 쉽게 프로그램 구조를 파악할 수 있다. 본 연구에서는 트리 구조를 사용하여 프로그램 코드를 구성해 나가면서 다른 도구의 도움을 받지 않고 손쉽게 각종 정보를 얻을 수 있도록 하기 위하여 브라우징 기법을 사용하는 도구를 설계하고 구현하였다.

The volatile odor compounds emitted form a stuffing agent production process were quantified by ATD and GC-MS, and then odor causing compounds were identified by the method of EOI using each TLV. As the results, 72 odor compounds were detected and total concentration was turned up 87.6 ppmv level. In these compounds, aldehyde group is higher 45.49 ppmv than others group, the next is turn up the order of aliphatics, alcohols, esters, ketones. The EOA of aldehyde group show up 101,720 and 97.2%, respectively, the odor causing compounds were identified each of odor 2-Octenal 28.31%, Hexanal 24.06%, Valeraldehyde 16.07%, Butyraldehyde 9.69%, Heptanal 4.97%, Propionaldehyde 4.64%, Acetaldehyde 3.31%. The TLVs of 7 major odor compounds are lower value level of 0.001∼0.0001 ppmv, odor causing even in trace level. We need to be concerned with reduction of aldehyde compounds in the odor problem by a stuffing agent production process or ironing process of the textile containing a stuffing agent.

To testify the hypothesis that BMD and serum lipid profiles might be different in women with leiomyoma, estrogen-dependent tumor, retrospective study was perfarmed in healthy women who visited Health Promotion Center in Samsung Medical center. One hundred sixty-one women with leiomyoma diagnosed by pelvic ultrasound examination were compared with 315 women with normal uterus. All women were divided into 3 groups accarding to serum FSH levels(mIU/ml)-group 1: FSH$lt;20, group 2: 20≤FSH$lt;35, group 3: FSH≥35. BMD tends to be higher in patients with leiomyoma than control. In group 1, women with leiomyoma showed higher femur BMD at trochanter and Ward's triangle(p$lt;0.05). Serum lipid profiles also seemed to be better in leiamyoma patients higher total and HDL cholesterol levels in group 1, elevated HDL cholesterol concentrations in group 2, and lower LDL cholesterol levels in group 3(p$lt;0.05). These data suggest that estrogen-sensitive markers such as BMD and serum lipid profiles tend to be improved in women with leiomyoma compared with control. A hyper-estxogenic state co-existing with leiomyoma might contribute to these differences. $quot;
