Researcher was interested in circumference of plane figure problem. Meanwhile, researcher found some difficulty in solving circumference problem with stair like plane figure. In this phenomenon, researcher felt to find the teaching method to help students with circumference of plane figure. For this, researcher analyzed many students' recording paper and had interview with few students. As a result researcher found that students had some difficulty in recognizing essential information and prior knowledge base was not made up. From these responses, this paper proposed teaching method for helping students about circumference related problems.

This study was carried out to evaluate degradation status of forest trails by analysis of soil physical and chemical properties in Mt. Jiri area of Gyeongnam province. Soil texture was loam in the forest area and sandy loam in the forest trails. Soil bulk density was significantly higher (P<0.05) in the forest trails (1.15 g/$cm^3$) than in the forest area (1.00 g/$cm^3$). The rates of pore space were lower in the forest trails (56.6%) than in the forest area (62.4%). Soil moisture content was significantly different (P>0.05) between the forest trails (13.3%) and the forest area (11.3%) Soil strength was higher at 5 cm of soil depth than at 10 cm of soil depth. It indicates that soil compaction by visitors could be affected at 5 cm of soil depth. Soil strength over 30 cm of soil depth was not significantly different between the forest trails and the forest areas. The content of organic matter, total nitrogen, available phosphorus, and exchangeable cations were lower in the forest trails compared with the optimum content of forest soils because of soil erosion with increasing visitors. These results indicate that it needs a counterplan to protect forest trails from overcrowded visitors.

흔히 뱃살이 나오는 것으로 표현되는 복부비만은 배에 과도한 지방이 축적된 상태로, 한국인의 허리둘레 기준으로는 남자 35.4인치(90cm), 여자 33.5인치(85cm) 이상인 경우에 해당한다. 지금까지 복부비만은 대사증후군의 일환으로서 당뇨병 발생 위험이나 심혈관계 질환의 위험을 높이는 것으로 알려져 왔으나 최근의 연구 결과에 따르면 허리둘레가 독립적으로 제2형 당뇨병 발병 위험과 밀접하게 연관된 것으로 나타났다.

Purpose: The aim of the current study was to compare body mass index (BMI) with waist circumference (WC) as a predictor of elevated intraocular pressure (IOP). Methods: The subjects were consisted of 458 adults, aged 20 year or above, of one community in Kyunggi-do. Mean IOPs were stratified jointly for BMI and WC tertiles. Multi-variate linear regression analysis was also used to compare between BMI and WC. Results: Although any BMI tertiles were not associated with IOP within each tertile of WC, WC tertiles was significantly related to elevation of IOP within the third BMI tertile (${\geq}24.9kg/m^2$). After adjusting for age and sex, only WC showed significant association with IOP. In additional adjustment for lifestyle variables, both BMI and WC were significantly associated with elevation of IOP. However, the results showed the stronger association of IOP with WC than BMI, whether they were adjusted by age and sex or additionally lifestyle variables. Conclusions: These data showed that BMI and WC were positively associated with IOP. However, WC appeared to be a better indicator for higher IOP than BMI.

This study suggests apparel sizing systems for obese women in their twenties to fifties. Size Korea body measurement data were used for sampling the obese subjects by obesity judgment indices. A total of 7 obesity judgment indices frequently used in the clothing field were inspected and the measurement data of 499 females defined as "obese" by over 5 obesity judgment indices were analyzed. The results of the study were as follows: A total of 2,212 female body measurement data for the Size Korea Project were collected. These were compared with the 499 data of the obese women in the study. Except for all heights and some lengths correlating with heights, the measurements of obese women were larger than the entire group of females. Bust girth, hip girth, and height were selected as control dimensions of the outerwear covering the upper body; waist girth and hip girth were selected as control dimensions of the outerwear covering the lower body. In each crosstabulation table, 3cm pitches and 5cm pitches by bust girth, waist girth, and hip girth were compared in the aspects of coverage and coverage efficiency. Finally, sizing charts for outerwear covering the upper body and the lower body of obese women were established in the study through the comparison of the coverage and the coverage efficiency. These Size charts were given by 5cm pitches as final sizing systems. Size number of outerwear covering the upper body was 10 and size number of outerwear covering the lower body was 9. In addition, the body measurements of control dimensions and referable dimensions for making garments are given.

내장지방을 손쉽게 측정할 수 있는 방법은 없다. 정확한 내장지방량을 알고 싶으면 병원에 가서 CT 촬영을 하는 수밖에 없다. 그러나 내장지방량을 알고자 CT 촬영을 하는 것은 소모적이다. 그렇다면 간단하게 알아보는 방법은 없을까. 있다. 바로 허리둘레를 재는 것이다.

The purpose of this study was to find out the body shape characteristics of each Sasang constitution typology. The constitution type of the subjects was determined by Sasang Constitution Analysis Tool(SCAT) and a Sasang specialist. The body circumference of the subjects and their respective proportions were analyzed. Concordance rates between SCAT and the specialist were 33.0% and 41.5% for men and women, respectively, and Soyangin had the lowest concordance rate. Forehead/neck, chest/iliac, rib/iliac, and rib/curvature circumference ratios of female subjects showed the same results in both SCAT and the specialist. In determining the constitution type, it was confirmed that the ratio between specific circumferences can be a more meaningful criterion than the circumference.
