Purpose : To know how much weight bearing on left and right leg on 14 different positions. The second is to know how about different the weight bearing ratio on same positions of ages group. Methods : The third is to know how about changes the weight bearing ration between exercise group and non exercise group. The group of age is divided 20s, 30s, 40s, 50s, over the 60 years. The subjects are 93 males(44), females(49). Results : The ordering of ratio of weight bearing on one side leg is as follows: The position of the highest weight bearing ratio is one leg standing with the other leg on chair(right 0.82, left 0.81) and the position of lowest weight bearing ratio is hooklying with natural leg position(both legs 0.08). There are statistically significant difference between right and left leg of weight bearing ratio on the 6 positions among the 14 positions. As for the ages, there are statistically significant difference on 5 different positions of 20 ages body weight bearing ratio between right and left leg. But as for the 50 ages there are no statistically significant difference on all of 14 positions between right and left leg body weight bearing. As for the exercise group there are statistically significant difference on only one position of one leg standing with the other leg on chair between right and left weight bearing ratio. But as for non exercise group there are statistically significant difference on 4 positions between right and left weight bearing ratio. Conclusion : When the therapist exercise with patient's always considerate of patient's position and weight bearing ratio.

Objectives : I'd like to mimic JunChenZuoShe Theory as Herb weight ratio grade. And than analyze the characteristics of the prescription based on the Herb weight ratio grade from Taepyeonghyeminhwajegukbang, Somunsunmyungronbang and Nansilbijang. Methods : At first, we have changed herb informations to Herb weight ratio. The second we have decided the ranking of herb weight ratio. The third we have entered herb weight ratio grade. Finally we have counted frequency of first grade herb from the Taepyeonghyeminhwajegukbang, Somunsunmyungronbang and Nansilbijang. Results : We could use a new search function to find prescription by herb weight ratio grade. And than we could find out prescription efficacy rate of the ancient documents. Conclusions : We have entered herb weight ratio grade values by herb weight ratio ranking of top 10%, 30%, 60%. So we could find out that buqi(補氣) efficacy is used most often in the Taepyeonghyeminhwajegukbang, Somunsunmyungronbang and Nansilbijang. In the rate of qingrezaoshi(淸熱燥濕) efficacy, fasanfengre(發散風熱) efficacy, fasanfenghan(發散風寒) efficacy, Nansilbijang is higher than Taepyeonghyeminhwajegukbang. In the rate of qingrezaoshi(淸熱燥濕) efficacy, gongxia(攻下) efficacy, Somunsunmyungronbang is higher than Taepyeonghyeminhwajegukbang.

The present study was undertaken to establish the decision standard of builds for the insured by using the ratio of weight-for-height as build index. Materials being examined were the ratio of weight-for-height being calculated from the actually measured heights and weights of a total of 15,838 insured persons who were examined medically at Honam Medical Department of Dong Bang Life Insurance Company, Ltd. from June, 1979 to September, 1985. The ratio of weight-for-height is calculated by the following formula. The ratio of weight-for-height(%)=$\frac{weight(kg){\times}100}{\{height(cm)-100\}{\times}0.9(kg)$ The results were as follows: 1. The distribution of the ratio of weight. for-height of the 15,838 insureds follows Log normal distribution being skewed to the left(the direction of underweight). 2. The ratio of weight-for-height were Log transformed to lead to a sym metrical pattern of distribution in which statistical rules are known to be applied more exactly. Thereafter, the establishment of dicision standard of builds was undertaken by using the log of the ratio of weight-for-height as build index. Through all ages in male, the ratio of weight-for-height indicating the range of standard lives including slight overweighted and underweighted lives besides normal lives is 80-130%, and corresponds to $"M-2{\delta}"-"M+1.5{\delta}"$ and to $M{\pm}20%$ ; in female, 85-135%, and corresponds to $"M-2{\delta}"-"M+1.5{\delta}"$ and to $M{\pm}20%$. Through all ages in male, the ratio of weight-for-height indicating the initial level of super-overweighted and super-underweighted lives is 130-150% and 75-80%,and corresponds to $M+3{\delta}\;and\;M-3{\delta}$ and to M+40% and M-25% respectively;in female, 140-160% and 75-80%, and corresponds to $M+3{\delta}\;and\;M-3{\delta}$ and to M+40%-+50% and M-25% respectively. 3. Author's rating table model for builds(a table of weight per height) is proposed. On the table, the ratings for builds, i. e. standard, super-weighted and super-underweighted lives, are listed.

This study aims at examining the correlations between waist-hip ratio, body fat, BMI, relative body weight and serum lipids by men and women in 40's and 50's. The subjects were 412 adults, who had regular health examinations between January and December of 1996 at S-Hospital in Seoul. The data were analyzed using unpaired t -test and Pearson correlation coefficient. The results were as follows : 1. The group of men had higher levels in waist-hip ratio, BMI, body weight , triglyceride, total cholesterol /HDL-cholesterol ratio , LDL-cholesterol /HDL-cholesterol ratio than the group of women. The group of women had higher levels in body fat and HDL-cholesterol than the group of men. 2. In the group of men, waist-hip ratio was more significantly correlated to serum lipids than body fat and BMI. In the group of women, body fat, BMI and relative body weight was more significantly correlated to serum lipids than waist-hip ratio.

A study on the standard cardiothoracic ratio calculated from the photofluorography film of chest in a total of 8,030 insured persons(3,449 men and 4,581 women) was undertaken. The results were as follows: 1) The linear regression equations were formed from the 99% confidence ilmits of actually measured average cardiothoracic ratio by weight index. The cardiothoracic ratios by weight index estimated by above mentioned equations, namely theoretic values of cardiothoracic ratio, should be regarded as the standard cardiothoracic ratios. 2) It seems that the standard cardiothoracic ratio${\pm}10%$ deviation should be regarded as the normal limits of cardiothoracic ratio. 3) The tables of standard cardiothoracic ratio by weight index and the normal limits of cardiothoracic ratio by weight index were presented. 4) The average weight index and cardiothoracic ratio in all males and females were 0.993 and 43.3%, and 0.997 and 46.3% respectively. 5) In order to evaluate the cardiothoracic ratio more accurately, the establishment of the standard cardiothoracic ratio by build is considered to be reasonable.

The National Fisheries Research and Development Institute (NFRDI) conducted a circle hook experiment to compare the catch rates of target and bycatch species between J hook and circle hooks in the tuna longline fishery of the Eastern Pacific Ocean, which is located between $9^{\circ}13'S-1^{\circ}36'N$ and $126^{\circ}00'-138^{\circ}21'W$. Sampling was conducted from September 20 to October 23, in 2006. In this survey, we collected shark data to obtain the ratio of fin weight to body weight of sharks. Overall, 413 sharks belonging to 9 species were caught on 62,464 hooks. The total weight of the sharks caught was 11,093 kg. The ratio of wet fin weight to body round weight of sharks by species ranged from 3.7% to 7.7%, while the mean was 5.4%. The total ratio of wet fin weight to the dry fin weight of sharks ranged 0.38 to 0.70 and the mean value was 0.53. The ratio of dry fin weight to the body round weight of the sharks was estimated to be 2.86%.

In recent years, the light-weight aggregate has widely been used to reduce the weight of construction structures, and to achieve the thermal insulation of building structures. The purpose of this study is to evaluate the heat resistance of polymer concrete composites with light-weight aggregate made by binders as resin and cement with polymer dispersion. The light-weight polymer concrete composites are prepared with various conditions such as binder content, filler content, void-filling ratio, light-weight aggregate content and polymer-cement ratio, and tested for heat resistant test, and measured the weight reducing ratio, strengths and exhaustion content of gas such as CO, NO and $SO_2$. From the test results, the weight reducing ratio of light weight polymer concrete using UP binder after heat resistance test increase with an increase in the UP content irrespective of the filler content. The weight reducing ratio of polymer cement concrete is considerably smaller than that of UP concrete. In general, the strengths after heat resistance of polymer concrete composites are reduced about 40 to 65% compared with those before test. The exhausted quantity of CO, NO and $SO_2$ gases in polymer concrete composites is less than EPS(Expanded poly styrene). From the this study, it is confirmed that the many types gases discharge according to binder type of polymer concrete composites, its amount is controlled by selection of the binder type and mix proportions.
