The purpose of this study is to propose prototypical plans for a dwelling unit applying the concepts of 'open housing' and 'aging in place' for senior citizens living in cities focusing on specific life patterns with chronic disease. Especially, a unit was designed for diabetes patients because diabetes, a representative disease of elderly people, often accompanies complications such as arthritis and Alzheimer disease. A unit design suitable for the convenient life of the elderly people with diabetes will provide a guideline for the similar unit designs of the senior citizens with other diseases. In this study, three types of unit plan are proposed. A-type plan is for type-1 diabetes patients, B-type alt.1 for the independent seniors of type-2 diabetes patients, and B-type alt.2 for the dependant seniors of type-2 diabetes patients. And a support design for a unit plan with the exclusive area of $60\;m^2$ is proposed. The same support design is used for all three unit types. Although the locations of bathroom and storage room are fixed and the location of the kitchen is changeable only in wet-zone. In conclusion, senior residents with diabetes can choose one of three unit types before occupation and the chosen unit type can be renovated by replacing infill systems as the health condition or life style changes.

Heat waves are not new, but due to climate change, the probability of occurrence and severity of heat waves increases, which results in more adverse impacts and damages on local community. Accordingly, the need to tackle heat waves in a more comprehensive and precautionary manner increases. Our study therefore lays emphasis on 1) a long-term plan which not only includes short-term plans in response to the observed damages, but also incorporates relevant sectors to deal with potential impacts in longer term perspective; and 2) a mechanism to manage and adjust the plan in a sustainable manner. In doing so, it examines the impacts of heatwaves and existing plans to tackle them. Based on that, two key conceptual frameworks, namely policy integration and adaptive management, are applied to provide strategies for the development and management of a long-term adapting heatwave plan addressing climate change.

Clothing is high-involvement products which is closely related with human being both physically and psychologically. It is the prod-uct bought by consumer repeatedly and needs lots of information according to the changing of modes. The comsumer is very sensitive to the advertisement when they purchase the clothing products. Therefore the importance of the advertising is remakably emphasized in these days. According to the qualitative and quantitat-ive growth of advertisement the unique mar-keting strategy must be deviced that is differ-ent from the past. This thesis focuses onthe importance of afection which is more pre-ferred when consumer contacts the advertise-ment. And this study purposes on the provid-ing the basic data to plan effective clothing advertisement by way of analyzing how atti-tude-forming affects the purchase intend of the comsumer. The findings of the study are as follows. 1. Sense-pursuit tendency is strongly ap-peared among the low-age not-married groups. 2. By the factor analysis of consumer re-sponse in each advertisement 5 factors proved to be valid ones 3. There were significant differences be-tween the brand-used and advertisement ex-perienced customers according to the adver-tisement/brand attitudes. 4. There were no significant differences be-tween the application of clothing advertise-ment and demographic character. 5. The affective response more affects on cognitive response and purchase intend in 4 modes of advertisement. 6. From the pathes of the brand-used experi-enced to purchase intend the characteristics showed up in each advertisement.

Due to earthquakes, many structures suffered extensive damages that were attributed to the torsional effect caused by mass, stiffness or strength eccentricity. Due to this type of asymmetry torsional moments are generated that are imposed by means of additional shear forces developed at the vertical resisting structural elements of the buildings. Although the torsional effect on the response of reinforced concrete buildings was the subject of extensive research over the last decades, a quantitative index measuring the amplification of the shear forces developed at the vertical resisting elements due to lateral-torsional coupling valid for both elastic and elastoplastic response states is still missing. In this study a reliable index capable of assessing the torsional effect is proposed. The performance of the proposed index is evaluated and its correlation with structural response quantities like displacements, interstorey drift, base torque, shear forces and upper diaphragm's rotation is presented. Torsionally stiff, mass eccentric single-story and multistory structures, subjected to bidirectional excitation, are considered and nonlinear dynamic analyses are performed using natural records selected for three hazard levels. It was found that the proposed index provides reliable prediction of the magnitude of torsional effect for all test examples considered.

The main purpose of this work is to compare different criteria for the seismic strengthening of RC framed buildings in order to find the optimal combinations of these retrofitting techniques. To this end, a numerical investigation is carried out with reference to the town hall of Spilinga (Italy), an RC framed structure with an L-shaped plan built at the beginning of the 1960s. Five structures are considered, derived from the first by incorporating: carbon fibre reinforced polymer (FRP)-wrapping of all columns; base-isolation, with high-damping-laminated-rubber bearings (HDLRBs); added damping, with hysteretic damped braces (HYDBs); FRP-wrapping of the first storey columns combined with base-isolation or added damping. A three-dimensional fibre model of the primary and retrofitted structures is considered; bilinear and trilinear laws idealize, respectively, the behaviour of the HYDB, providing that the buckling be prevented, and the FRP-wrapping, without resistance in compression, while the response of the HDLRB is simulated by using a viscoelastic linear model. The effectiveness of the retrofitting solutions is tested with nonlinear dynamic analyses based on biaxial accelerograms, whose response spectra match those in the Italian seismic code.

This study analyzed the isolation effect for a 15-story reinforced concrete (RC) building with regard to changes in the beam-column stiffness ratio and the difference in the vibration period between the superstructure and an isolation layer in order to provide basic data that are needed to devise a framework for the design of isolated RC buildings. First, this analytical study proposes to design RC building frames by securing an isolation period that is at least 2.5 times longer than the natural vibration period of a superstructure and configuring a target isolation period that is 3.0 s or longer. To verify the proposed plan, shaking table tests were conducted on a scaled-down model of 15-story RC building installed with laminated rubber bearings. The experimental results indicate that the tested isolated structure, which complied with the proposed conditions, exhibited an almost constant response distribution, verifying that the behavior of the structure improved in terms of usability. The RC building's response to inter-story drift (which causes structural damage) was reduced by about one-third that of a non-isolated structure, thereby confirming that the safety of such a superstructure can be achieved through the building's improved seismic performance.

Recently, natural disasters happened to the Korea frequently. Disaster in the present society has been changed and increased it impacts and extent of danger as the society develops. So, Korean people feel uneasy about the unpredictable disaster. Therefore the capability of administration system, and cooperation and support between related organization become more necessary. This study aims to find out better ways of disaster management system which can protect people's lives and fortune from all sort of national disasters. To research policy reform, it is necessary to analyze disaster response organization(national disaster prevention countermeasures headquarters and so on), interorganizational relationship, law system etc. Especially, in this study, role appreciation of government was analyzed to get the rational policy reform measure. Suggestion : First, it is necessary Establishing a consolidated organization for disaster managing and united response organization is necessary such as Federal Emergency Management Agency(FEMA) which controls an over all aspects of disaster management. And it is necessary to develop Integrated Administrative Control System based on comprehensive plan. When the accidents happen, it needs to be many equipments and various specialized personnel. So, to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. Also, as soon as the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, All the citizens have to keep safety rules, and also to take a safe action in ordinary daily life.

Time domain response analysis for vibro-impact nonlinear behavior of multi-span tube with loose supports was performed using commercial FEA code and user subroutine. Support geometry of multi-span tube with a finite gap is realistically modeled by analytical rigid surface. Model of hydrodynamic force is based on the Qusai-steady model which accounts for the inclined angle of relative flow velocity and time delay between flow force and resulting tube motion. During tube vibration from flow loading, impact and friction at the support location is simulated using commercial FEA code with master slave contact algorithm. Analysis results has reasonable agreement with those of references and test experience. Plan of further refinement of analysis model and future test verification is briefly introduced.
