The purpose of this study is to analyze the research trends and characteristics in the research subjects related to the housing for the elderly in Korea. The number of 199 studies was selected from the paper of Architectural Institute of Korea. The data of the present condition for welfare facilities are exploited from Korea National Statistical Office. The elderly welfare facilities are divided as 5 kinds of things ; housing facilities, medical facilities, leisure facilities, retired facilities and mixed facilities. And policy and statutes of welfare facilities are included in this study. The data were analysed with contents and chronological order and then the trends of research were studied by facilities. As the results of study, studying about housing facilities is well progressed but, the other parts of studying are little short. Especially, studying for retired facilities is seldom done so we need systematic survey and study.

The purpose of this study is finding the easy way of 4 categories activity level confirmation for estimated energy requirement calculation. Total of 386, 5th and 6th grade primary school students participated. The time spent on 7 kinds of activity were collected for 1 day by the internet program developed. Judged by the activity coefficient, sedentary were 6.7% and 5.1%, low active 33.2% and 40.4%, active 43.8%, and45.5%, and very active 16.3% and 9.0% for boy and girl, respectively. The highest and significant correlation coefficient between activity coefficient and time spent on activities shown were 0.339 in commute activity for boys, and 0.466 in leisure for girls. The sensitivity of the sedentary conformation by commute hour for boys was 0.79, and that of very active was 0.56. The sensitivity of the sedentary conformation by leisure hour for girls was 0.67, and that of very active was 0.63. The sensitivity of low active and active by 7 different types of activity was quite low, 0.04~0.37. The exact agreement of activity level conformed by easy way developed was 30.8% and 33.7%, for boys and girls, respectively. More accurate way to identify 4 categories activity level needs to be developed, especially sensitive to conformation of low active and active levels.

Because there is no suspension and differential devices at cart body, the deformation of the frame happened during kart driving affects the driving performance caused by the elastic deformation and the fatigue life of kart frame resulted from the permanent deformation. The dynamic behavior of kart caused by the torsional deformation during circular driving is the important factor of these two kinds of deformations. In order to analyze the dynamic behavior of kart at this curved section, GPS is used to trace the track of kart and the torsional stress at kart-frame has been measured with real time. The mechanical properties of kart-frames for leisure and racing are investigated through material property analysis and tensile test. Torsional stress concentration and frame distortion are investigated through stress analysis on frame on the basis of study result. The real karts for leisure and racing kart are also tested in each driving condition by using the driving analysis equipment. The driving behavior of kart at the curved section are investigated through this test. As the phenomenon of load movement due to centrifugal force at car is happened during circular driving, the torsional stress occurs at cart steel frame.

The purpose of this study is to make it clear that the influence the adults' work-family conflicts affect the family life satisfaction and the work life satisfaction of theirs, according to the personal backgrounds (sex, age, monthly income and whether the person works S days a week or not). The target group of this study is the selected 754 adults who are married with children that are in the employ of the various companies in Seoul and Incheon. The picked data are analyzed to factor analysis, frequencies, means, One-way ANOVA and multiple regression analysis etc..using Spss 11.5 version statistical program. Following is the result of the study: First, the level of work-family conflicts have been shown to be different as the result of verification by sex, age, monthly income and the type of duty(whether working 5days a week or not) out of the personal variables. The study shows that the level of work-family conflicts is different by the subordinate variables of work-family conflicts as the results of male and female comparison. And the older the age, the higher the level of family conflicts.'rho study shows that The level of the places of work conflicts is the highest in the 30s. The smaller monthly income, the higher the level of work-family conflicts. The study shows that the level of family conflicts is high in working 6days a week and the level of work conflicts is high in working 5days a week. Second, such factors for conflicts at home as family support, family expectations and financial difficulties affect the level of satisfaction at work, while such personal backgrounds as monthly pay, kinds of work and age level also play a role. At the same time, satisfaction in family life is influenced by such factors for conflicts at the places of work as support, involvement, expectations and work-overload at the places of work, with such personal backgrounds as monthly pay, age and sex compounding the impact. On the point how much conflicts at work and home affect the satisfaction at home, work and leisure, the study shows that family life does not have noticeable influence in the level of satisfaction at the places of work, whereas situations at the place of work have significant impact on the level of satisfaction in family lives. In other words, the lesser conflicts the work situations cause to family lives, the greater the level of satisfaction at work, home and at leisure.

Recently, design technology of has been required such as catamaran yacht with high-speed according to expand a marine leisure industry. The domestic technical development for design and production of yacht is not actively than Canada, USA, Japan etc. However, with further development of yacht design & technology, it is need to develop a key technology related to increase the value of catamaran yacht. In the present paper, new guideline is suggest for catamaran yacht as like kinds of marine leisure ship in order for fundamental structure design and structural analysis for twin-hulled ship yacht and techniques for structural analysis as sea leisure ship in this research. The class of society has not been proposed formally about regulation and methodology for estimation of strength of small hight-speed craft with satisfying two conditions as noted; length less than 50meters, ratio of length to breadth less than 12. In the present study, we were adopted DNV (Yachts, Design Principles, Design Loads, Hull Structural Design) Rule and KR (FRP rule application guide) for scantling of structural members. Furthermore, ABS rule is used for structural calculation about application of loading conditions for catamaran yacht. This study can be available feedback role to manufacture of 38ft diffusion style for catamaran yacht. It is expected that this study will be a good reference in order to design of catamaran yacht with high-speed.

Elastic deformation and fatigue damage can cause the permanent deformation of a kart's frame during turning, affecting the kart's driving performance. A kart's frame does not contain any suspension or differential devices and, therefore, the dynamic behavior caused by torsional deformation when driving along a curve can strongly affect these two kinds of deformations. To analyze the dynamic behavior of a kart along a curved section, the GPS trajectory of the kart is obtained and the torsional stress acting on the kart-frame is measured in real time. The mechanical properties of leisure and racing karts are investigated by analyzing their material properties and conducting a tensile test. The torsional stress concentration and frame distortion are investigated through a stress analysis of the frame on the basis of the obtained results. Leisure and racing karts are tested in each driving condition using driving analysis equipment. The behavior of a kart when being driven along a curved section is investigated through this test. Because load movement occurs owing to centrifugal force when driving along a curve, torsional stress acts on the kart's steel frame. In the case of a leisure kart, the maximum torsional stress derived from the torsional fatigue limit was found to be 230 MPa, and the torsional fatigue limit coefficient was 0.65 when driving at a speed of 40 km/h. Furthermore, the driving elements during the cornering of a kart were measured based on an actual auto-test after installing a driving measurement system, and the driving behavior of the kart was analyzed by measuring its vertical displacement.

The purpose of this study was to investigate the spatial composition characteristics of elderly housing facilities in Korea, in order to refer them in establishing the basic plan for elderly housing in Korea. The case study performed in this study from October 16 to October 31 is based on ten housing facilities for the elderly in KOREA. During the site visits, the interview with the custodians, survey of the space, picture taking and diagram gathering were carried out. The results of this study were as follows; 1. The type of floor plan was classified into ㅁ type, L type, and ㅡ type. And they hadn't an outside space called a garden(courtyard). 2. The kinds of common spaces could be grouped as the space for basic living, for leisure, and for convenient living. Also it was all common that the housing facility had common diningroom laundry room once, and activity room. The type of the common spaces was categorized into three types, the centralized type where the shared space was located at the center of the housing facilities, the distributed type, depending on the degree of separation between common spaces and units, and another each building type. 3. The kinds of units was classified into studio, oneroom, one bedroom and two bedroom. 4. Elevator, safety grab bar, emergency bell, and the door handle of lever or bar type were placed in these facilities.

The purpose of this study is first to examine the tendency in what kinds of activities are carried out as family rituals; what kinds of obstacles there are; and why any problems, if any, tend to arise. Second, the study seeks to discern the relationship between family rituals and wives' marital satisfaction. For this purpose, the study surveyed 251 wives who had fourth, fifth, or sixth grade children and resided in Busan, and then analyzed the data obtained from the survey. The major findings of this study can be summarized as follows: (1) Regarding the dinner ritual, it turned out that a majority of subjects had a difficult time establishing a regular ritual due to 'their busy schedule at work' and 'children's studying at academies'. For the weekend leisure ritual, in the case of difficulty in spending this kind of time it tended to be because of the wives' 'busy schedules at work' and 'lack of mutually available time for all family members'. In birthday rituals, when wives reported having trouble with her family members regarding birthdays, they explained that this was most often' because family members forget their birthday'. Finally, when the subjects reported problems related to tradition rituals, it was mainly because of 'stress from the burden of housework (2) In every dimensions including occurrence, routine, deliberateness, attendance, affect, and symbolic significance, the top-ranked group showed a high degree of satisfaction in their marriage.
