The aim of this research is to grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. And so, this writer had questionaired the 400 middle-aged couples in five gus, Taejon megalopolis -Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from April 21, 1998 to May 10, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows. 1. 145(69.37%) subjects of total 209 had experience in lumbago after their sexual lives. 2. In the number of sex life a week, one or two times of lumbago incidence rate were the most rate as 41.55% and each other had a statistically significant relation (P 0.01). 3. In age and lumbago incidence rate, their thirties was 37.75% and each other had a significant relation (P 0.05). 4. In weight and lumbago incidence rate, the level of $50kg{\sim}60kg$ was highest and each other didn't have a significant relation (P 0.05). 5. In the mean time of sexual life, the period of $11{\sim}20$ minutes was 29.47% and each other had a significant relation (P 0.01). 6. In week time zone of sexual life and lumbago incidence rate, midnight was the highest rate, 36.23% and each other didn't have a significant relation (P 0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P 0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate, 46.12% and each other didn't have a significant relation (P 0.05). Putting the abovesaid results together, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. Therefore, it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an education for lumbago prevention, etc. the key points.

The purpose of this research is to be grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. This writer had questionaired the 400 middle-aged couples in Taejon city - Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from June 1, to June 30, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows; 1. 145(69.37%) subjects of total 209 had low back pain experience after their sexual lives. 2. In the number of sexual times a week, low back pain incidence were the most rate in 1-2 times as 41.55%, each other had a statistically significant relation (P<0.01). 3. In age and lumbago incidence rate, the 30s was 37.75% and each other had a significant relation (P<0.05). 4. In weight and lumbago incidence rate, the level of 50kg~60kg was highest and each other didn't have a significant relation (P>0.05). 5. In the mean sexual time, the period of 11~20 minutes was 29.47% and each other had a significant relation (P>0.01). 6. In a day time of sexual life and lumbago incidence rate, midnight was the highest rate(36.23%) and each other didn't have a significant relation (P>0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P>0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate(46.12%) and each other didn't have a significant relation (P>0.05). According to the results of our research, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. So it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an prevention education for low back pain the key points.

The purpose of this study was to obtain and offer useful information on innerwear industry through an analysis of consumer purchasing behavior and preference of their between the 20's and 60's. From 310 questionnaires that were distributed, 310 with usable data were coded for further statistical analysis including descriptive statistics(frequency and chi-square test), by using SPSSWIN 10.0. The results were as follows: The results show that since the surveyed women's purchasing patterns were varied according to their ages it is necessary to develop new items and designs tailored for particular needs and wants of each age group. For those in their 20's, it is suggested that the innerwear design may consider reflecting the trend of the young women nowadays as characterized by a major fashion-led group who regard fashion as a way of expressing themselves and are not hesitant to wear clothing designed to be exposed their body. The innerwear products for women in their 30's and 40's should emphasize on the aspects of customizing and satisfying these women's different lifestyles. The study also reveal that for age groups of the 50's and 60's women these products should be developed in a way to intensify functions of thermal property and absorbency coupled with a classic design rather than daring styles. In conjunction with material developments it is necessary to establish a sizing system for the knitted innerwear products which reflect the specific characteristics of women's body type in their middle-and later years.

This study was to understand the basic principles of the East Asian wooden structure system research and analysis. The Korea and China ancient architecture internal structure research that the combination of girders and crossbeams position. The ancient wooden structures of eastern Asian countries, Korea and China are not much different from each other in the principles of the wooden architecture structure, combining pillars, purlins and crossbeams. However, it seems that age-division, local-division, national-division differs in detail techniques. China ancient wooden structures combination of purlin and crossbeam, and So-seul Timber(Chinese name: Chashou叉手, Tuojiao 托脚) seems to show differences according to the age of the fulcrum position, detailed approach is also different according to various historical dynasty. Before in the 15th century, Purlin and Crossbeam are coupled to each other, but since the 15th century, seems to have developed a technique combined with each other Girder and Crossbeam and to prevent buckling of the Crossbeam cross-sectional area increased dramatically. For Tuojiao in China Tang-Wudai dynasty(A.D. 618~979), can see that saw the top position Girder and Tuojiao no direct coupling, can be seen as maintaining the safety of the material than the material of the inner wooden structures prevent buckling of the purlin. Korea ancient wooden structures of Goryeo dynasty(A.D. 918~1391), So-seul Timber(Chinese name Tuojiao) why do not to use the fashion? To use Purlin Lower backing material techniques to prevent buckling is a popular trend to stable can be thought of as a preferred way to maintain. I think that with universality beyond the local-division, national-division and the two countries since the 15th century of Korea and China ancient wooden structures detailed mechanism for the purlin buckling. In middle-late Chosen dynasty, The effect of Deotgeolyi- techniques and fleeting beams reduce the purlin buckling that reduces the load transmitted from purlin and crossbeam of how to reduce the load on the roof portion of the architecture fleeting beams used, which of craftsmanship of the Chosen Dynasty building can be referred to as another technique for preventing buckling purlin. This Korea and China ancient architecture purlin beam structure and material So-seul Timber study. Seems to be able to provide a basic research study to restore and designed the old wooden architectures.
