Purpose: The most previous works on designing accelerated life tests (ALTs) are focused on the application of a single stress. Because of the difficulty to obtain the sufficient information in a reasonable duration using single stress only, there is needed in practice to use multiple-stress ALTs frequently. This paper presents new practical plans with two stresses for Weibull distribution. Methods: The four-level practical plans based on rectangle test region are proposed and compared with the corresponding three-level statistically optimal plans. Sensitivity analyses for assumed design parameters and life-stress relationship are conducted. Results: A procedure to choose practical ALT plans is illustrated with a numerical example and guidelines for planning two-stress ALTs are provided. Conclusion: The proposed two-stress ALT plans on practical constraints to assess a quantile of Weibull lifetime distribution at the use condition are efficient and robust.

Currently, China's urban landscape is undergoing a gradual shift from incremental development to stock renovation. Furthermore, the planning and development objectives of urban communities have evolved from solely focusing on physical space construction to promoting sustainable development within a humanistic society. The current approach to community planning and construction, which emphasizes a singular dimension of residential life, overlooks the multifaceted aspects of community life and production. This oversight leads to a lack of attention to interpersonal relationships within the community, difficulties in establishing a connection between people and their environment, and numerous other issues. Consequently, this paper seeks to redefine the concept of sociality within community spaces by considering the continuum of time and space within communities. It aims to delineate the roles of "power" and "rights" within the community context, with a particular focus on everyday life, in order to reevaluate strategies and methods for fostering dynamic community development.

Recently, the architecture remodeling is rising as new alternative for activating the construction market as the interest toward life cycle of buildings has increased. But the reality is that current remodeling business is suffering various types of difficulties in its performance due to the absence of general management technology and factor technology in systematic performance procedure or evaluation, etc toward remodeling effect, evaluation on performance, imperfect system for reflecting user requirements and remodeling life cycle ; planning, $feasibility ^{\circ}\hat{E}designing^{\circ}\hat{E}construction^{\circ}\hat{E}management$ along with lack of overall understanding on remodeling. Accordingly, this research has attempted to search for an effective management method through overall understanding in project performance by presenting work procedure of remodeling project and analysis items for decision making, etc centered on early planning stage out of three stages called planning, designing and construction.

Recently, due to the growing concern of the public in rural amenities and hobby farming works, much more urbanites, especially near-retirees, have been interested in rural life style than before. However, in spite of popular preference to ruralities, little has been known about their demand on retired rural life. Therefore, this study examined urbanites' attitude to preparatory works for out-migration, preferred residential site conditions and life style in the countryside. For this purpose, data were collected from a survey with the sample of 386 urban residents aged 40 to 65 rho hoped moving into the countryside after retirement, through structured questionnaires. Descriptive statistical works were performed using SPSS/PC windows program. The major findings of this study were as follows; (1) Host of urbanites, who answered in this study, planned to prepare ex-urban movement in their fifties and to put into practice in their sixties. (2) Key factors of location decision on movement were proximity/accessibility to centre city, medical service level, and distance to their family or friends. And about a half of respondents wanted second home in the countryside. (3) Most favoured rural life styles were nature-friendly well-being and hobby/healthy firming. Generally, the respondents of this survey had the positive attitude to do works in their later life, especially preferred to farming and volunteering in their communities.

This study is an experimental study that examines the policy attributes that local governments should choose to manage the quality of life of rural residents. The analysis data used raw materials for the survey of the welfare status of farmers and fishermen surveyed by the Rural Development Administration. The analysis method used Quantile Regression. The policy attributes of public services were interpreted on the basis of Peterson (1981)'s theory of policy types and the discussion of Holland (2015). According to the analysis results, the higher the quality of life, the greater the importance of the relationship between the safety sector and the neighbors. The effective policy attributes for improving quality of life in rural areas are the policies of local governments where policy benefits can directly go to individuals, or lead to social improvement. It shows that the higher the level of safety and the quality of life of our neighbors, the greater its importance.

Using the life cycle cost concept, optimum maintenance and retrofit planning for reliable seismic performance is suggested the overall life cycle cost to be minimized including the initial cost, the costs of inspection, repair, and failure. Limit states of the bridges are defined. And failure probabilities are computed through crossing theory. The effect of maintenance and retrofit is represented using the probability of damage detection and event tree analysis. Optimization of maintenance and retrofit planning method proposed from this research was applied to numerical examples. The analysis incorporates the acceleration and site conditions prescribed in the code, and the quality of inspection methods.

Data were collected from questionnaire with 772 married women who were residents of Jeonju. The major finding were as follows; (1) The levels of financial management and financial goal attainment on housing purchase and children's educational expenditure were middle. (2) The variables which exerted direct effects on financial goal attainment on housing purchase were time orientation of consumption life, asset, income stability, easiness in extending credit, financial planning, and financial implementing. the most powerful predictor of financial goal attainment on housing purchase was asset. (30 The variables which exerted direct effects on financial goal attainment on children's educational expenditure were time orientation of consumption life, asset, children's presence on the camp8us, easiness I extending credit, financial planning, and financial implementing. The most powerful predictor of financial goal attainment on children's educational expenditure was financial planning.
