Healthy Japan 21의 목적은 삶의 질을 향상시킴은 물론 노동가능 인구집단의 유병률을 줄이고 건강수명을 연장시키기 위하여, 21세기 모든 일본인들이 더욱 건강하고 행복한 삶을 향유할 수 있도록 국가사업을 활성화하는 것이다. 구체적 목적은 조기사망을 예방하고 건강생활을 향상하는 것으로, Healthy Japan 21의 전략적 기획과정에서 건강수명의 연장을 실현하기 위하여 2010년까지 달성되어야 하는 구체적인 목적들이 또한 제시되었다. 조기사망을 감소시키기 위하여 사고, 암, 자살, 심장병 감소의 중요성을 인식하고 9개의 주요 목표로 영양, 신체활동, 휴식과 이완, 금연, 절주, 구강보건, 당뇨병 예방, 심혈관계질환 예방, 암 예방을 설정하였다. 흡연, 알콜, 식사 그리고 운동과 같은 생활양식은 스트레스, 비만, 고혈압과 같은 위험요인 및 질병관리와 관련이 있으며, 위험요인은 암, 심장병, 구강질환의 발생과 밀접한 관련을 갖는다. 따라서 질병의 발생을 예방하기 위해서는 건강증진과 일차예방이 강조되어야 한다. 일차예방에 중점을 두기 위해서 우리는 전통적인 질병관리의 중점사항인 정기적인 건강검진을 통해 질병 조기발견을 노력을 게을리 하지 말아야 할 것이다. 아울러 의료비 감소, 병상에 있는 사람들의 감소, 사회세의 감소도 또한 달성되어야 하는 사업의 결과로 설정되어 있다. 가장 최근의 Healthy Japan 2000(1998-99)의 평가에 따르면 목표들의 15%가 달성되었거나 초과 달성된 것으로 나타났다. 이 중 아동과 청소년의 사망률의 경우, 1-14세 아동의 사망률은 1987년부터 26%가 감소되어 2000년도 목표인 인구 100,000명단 28명의 사망을 초과 달성한 것으로 평가되었다. Healthy Japan 21의 두 가지 주요 전략은 일반 인구집단을 위한 전략과 고위험 집단을 대상으로 하는 전략으로 구성된다. 개인의 건강한 생활양식으로의 변화를 포함한 우리의 건강증진 노력은 사람 중심으로 개인의 선택을 기반으로 하고 있다. 이러한 노력을 지원하기 위하여, 각 개인이 정보를 갖은 상태에서 올바른 선택을 할 수 있도록 적당량의 올바른 정보를 제공하는 것이 필수적이다. 이와 같은 일본의 건강증진계획은 2000년 3월에 Healthy Japan 21이 설립되었으며, 2000-2002년 사이 모든 현이 자신의 사업계획을 설정하였으며, 2001-2005년에는 약 반수 정도의 지방자치단체들이 자신들의 사업계획을 확정하였다. 건강증진을 이루는 중요한 수단은 파트너 쉽에 있다. 정부조직 뿐 아니라 건강보험회사, 보건의료서비스 제공자, 교육단체, 대중매체, 사기업, 봉사단체 등을 포함한 건강분야의 조직들은 자신들의 전문적 기술들을 한데 모아 서로 협력하여야 한다. 또 하나의 중요한 수단은 건강 지지적인 환경이다. 개인의 건강증진 노력을 체계화함으로써 지지적인 환경을 조성할 수 있다. Healthy Japan 21에 대한 평가는 2005년에 중간평가가, 2010에 최종평가가 있을 예정이다. 평가결과들은 이후에 진행될 사업의 향상을 위한 기준으로 활용될 예정이다.

The purpose of this study is to investigate the level of mother's caregiving satisfaction of a person with mental disorder and factors influencing to it as a positive aspect of caregiving experience. A survey conducted upon 231 mothers who live together with their adult-children with mental disorder through community mental health centers, social rehabilitation facilities and day hospitals. Collected data were analysed by t-test, Oneway-ANOVA, hierachical multiple regression analysis, and so on. The results are as follows: 1) The mean of mother's caregiving satisfaction is 3.06 in 5 point scale. Among the total items of the caregiving satisfaction scale, the means of the items 'finding strength through caregiving' and 'personal growth through caregiving' are higher than any others. 2) In the final regression model, statistically significant factors influencing to the caregiving satisfaction are 'the relationship quality between mothers and the mentally disordered', 'perceived social support from family, significant others, and friends', 'marital status of mothers', and 'family income'. Better relationship quality between mothers and the adult children with mental disorder and higher social support from family, significant others, and friends explained higher caregiving satisfaction of mothers. The level of a widow or divorced mother's caregiving satisfaction is higher than married one. The less family income affected to higher caregiving satisfaction. Variables related to mental disorder of adult-children, such as social function, years of mental disorder and frequency of hospitalization were not statistically significant influencing factors to mother's caregiving satisfaction. Through this research, the implications of social work practice were suggested in many ways.

Both static pile load test with load transfer measuring system and the pile dynamic load test are performed to estimate the skin friction and behavior characteristics of a large drilled shaft. And the numerical modeling of large drilled shaft is performed by applying the FDM program. Since the magnitude of friction resistance depends on the relative displacement between soil and shaft, load and displacement at the arbitrary depth along the large drilled shaft are estimated to analyze the correlation. According to the measuring results of load transfer, unit skin friction along the large drilled shaft was fully mobilized at gravel layer in the middle of shaft and the frictional resistance transmitted to bedrock was relatively small. Also, even for the same drilled shaft, the results of PDA and static load test are different with each other and the difference is discussed.

The influences of the coupler consisting of stiffness and mass between neighboring two spans on mode localization are studied theoretically, and the results are confirmed by numerical examples. The mass of the coupler makes a structure sensitive to mode localization especially in higher modes while the stiffness does in all modes. A new type of delocalization phenomenon is observed for the first time in some modes for which mode localization does not occur or is very weak although structural disturbances are severe. A spring-mass system consisting of two substructures and a coupler connecting them is considered in the part of analytical study. As example structures for numerical analysis. simply supported continuous two-span beams with a coupler having a rotational stiffness and a mass moment of inertia on the mid support are considered.

The purpose of this study was to examine the effect for information load on perceived information quality and website quality, and the relationships among perceived information quality, website quality and behavioral intentions in online apparel shopping contexts. The information load theory provided the theoretical framework for this study. The research strategy employed an online experimentation using an apparel mock website. The total of 647 responses were used for data analyses. The model of the study was tested by MANOVA and SEM. The results of MANOVA revealed the effect of information load on perceived information quality and website quality. The medium level of information load was perceived as having more positive information quality and website quality as compared to the low or high level of information load. The findings of SEM revealed the positive effect of information quality on website quailty, the positive effect of website quality on WOM and willingness to pay more, and the negative effect of website quailty on willingness to switch. Online apparel retailers and website designers need to manage information quantity and quality by understanding the importance of information load.

To suggest a modified shallow foundation design method which can be considered the scale effect of foundation on IGM(intermediate geomaterial) soil layer, the weathered soil layer that is uniformly formed up to 8m(2B) with over 50 N-value is selected and 3 times field loading tests are performed on several sized square-shaped shallow foundations with 30, 75, 150, 240 and 400cm in width respectively. Because the soil modulus of elasticity(Es) calculated by soil investigation and 1st field test(PBT) results showed an underestimated tendency, a modified correlation is required for the reasonable estimation of Es on the weathered soil. Also, the N-value was increased with an increasing in depth. However, the N-values around the test foundations showed the different values even though the foundations on the same level because the test site was arranged by excavation. Therefore, the more detail soil investigations are required for the each test foundations respectively. Since Es based on elasticity theory is determined by the stress distribution shape of the foundation and elasticity modulus of the soil, the scale effect considered pressure-settlement curve can be clearly derived from the correlation on stress distribution shape and the variation of soil elasticity modulus with depth. Therefore, the modified correlation will be suggested to estimate a reasonable Es on the weathered soil, and the scale effect considered shallow foundation design method is also developed based on the elastic theory and field tests in this research.

In this study, centrifuge tests were performed to investigate the effect of the lateral load-moment combination on the p-y curves for 7 m-diameter monopiles installed in sand for offshore wind turbine. For the objectives, a centrifuge testing system was developed and tests were conducted at an acceleration of 68.83 g using well-instrumented model monopiles under two different lateral load-moment combinations simulated by different loading heights: 1 and 5 times monopile diameter from the ground surface. The sand was prepared as medium loose sand. Based on the centrifuge test results, the experimental p-y curves were evaluated and compared with previous literatures including API codes. The experimental results reveal that the p-y curves were little influenced by the combination of lateral load and moment. It was also found that the embedded length affects p-y curves.

The stress and deformation behavior safeties of cylindrical hollow rollers have been analyzed by the finite element method, and investigated for over design capability based on the computed results. According to the stress analysis result which is related to the strength of a hollow roller, the maximum stress of 39.8MPa in which is operated near the bearing for supporting a hollow roller structure is overestimated design as 15.9% level compared with a yield strength, 250MPa of a steel material. And the maximum deformation of 0.032mm in which is operated at the middle span of a total length of cylindrical hollow rollers is very small and sufficiently safe compared with a total length and a thickness of a hollow roller. Thus, the FEM computed results for a stress and deformation indicate that a current FEM analysis model of cylindrical hollow rollers is over designed.

The rapid spread of Internet has significant effects on changes in the distribution channel. The direct transaction between manufacturer and consumer could create the threats of dis-intermediation to existing channel members as middlemen. Air-ticket market also has changed in Internet marketing channel era. This study is mainly concerned with understanding the reaction of travel agency to Internet marketing channel. The objectives of this study is to propose and test the model that the perceived threats of dis-intermediation affect the reactions of travel agency: increasing channel competence, decreasing concentration, and deriving diversification. The model basically adopted the arguments of intertype competition, considering the arguments of re- intermediation in order to explain the reaction of using Internet. The result of survey from 158 travel agencies supported most of hypotheses. All the hypotheses are accepted except the relationship between threats of dis-intermediation and increasing channel competence.

During construction of circular lifeline pipe, the non-proper compaction along the pipe and the decrease of compaction efficiency are the main problems to induce the failure of underground pipe. The use of CLSM(controlled low strength materials) is one of the applications to overcome those problems. In this research, the numerical analysis by PENTAGON FEM program was carried out for 20 cases with the couple of combinations on bedding materials, backfill materials, and pipes. From the FEM analysis, the use of CLSM as backfill materials reduced the settlement of ground surface and the deformation of pipe employed. In case of the vertical deformation on the pipe, common soil backfill for flexible pipes showed 2 times for rigid pipes, but CLSM backfill case did less deformation than the soil backfill for rigid pipes. CLSM backfills for rigid pipes showed the similar results. Judging from the FEM analysis, the use of CLSM increases the structure capacity of the underground pipes.
