The primary purpose of this study is to provide the managerial guidelines for the comprehensive apartment improvement planning. This plan will consider the time-serial apartment management plan. Through a questionnaire survey, residential satisfactions and demands on apartment units, apartment building and site amenities were investigated. Based on the statistical analysis, residents' demands were assessed. The resident groups were categorized into the three groups considering the apartments' life span where they were living. The results from the statistical analysis were finally compared with the long-term apartment management plan demonstrated in the Housing Code of the Ministry of Construction and Transportation. The major findings of this study were as follows. First, residential satisfaction on the equipments in apartment units was higher than that on the unit plans. Residents' satisfaction on the communal facilities in apartment sites was lower than that on the other factors. Thus, apartment unit plans and communal facilities in sites need to be improved. Second, though we had the three residents' groups, for the results of the residential satisfaction, the groups were divided into two groups: 'less than 10 years group'and 'over than 10 years group'. Considering the residents' demands for the apartment improvement according to the life span of apartment complexes, the habitability factor was demanded by 'the less than 10 years group' and the safety factor by 'the over than 10 years group'. Compared the residents' demands for apartment improvements with the long-term apartment management plan demonstrated in the Housing Code, the improvement cycles demanded by residents were shorter than those in the code. Thus, the management plan in the code should be reconsidered.

Since modern times, lack of housing had become more serious in the cities when going through urbanization process. As a countermeasure against the situation, multi-family houses raised its head at the end of 1980s. Regarding multi-family houses, which is mainly targeting low-income group, however, only quantitative supply has been focused with no enough research about space planning. For now that the supply of housing in the cities reached certain level, there is a need of planning multi-family house considering the demands of residents. Therefore, the purpose of this research is to identify and analyze the demands of owners and tenants of multi-family house in an improvement district of housing environment for housing improvement, and to extract house planning components. As a research methodology, small-group workshop panel using drawings and mock-up has been practiced to reach residents' concertized opinion. After dividing the residents group into 2 groups which include owners group(3 participants) and tenants group(3 participants), 3 times of workshops covering 2 days are conducted for each group. Actual-condition investigation of the participants' houses was ran side by side with workshop. As a result, difference in their point of view about the reasons and the direction of housing improvement was identified, on the other hand that there is similarity in their demands such as guaranteeing independency and privacy among households.

This paper investigates inelastic seismic demands of the normal component of near-fault pulse-like ground motions, which differ considerably from those of far-fault ground motions and also parallel component of near-fault ones. The results are utilized to improve the nonlinear static procedure (NSP) called Displacement Coefficient Method (DCM). 96 near-fault and 20 far-fault ground motions and the responses of various single degree of freedom (SDOF) systems constitute the dataset. Nonlinear Dynamic Analysis (NDA) is utilized as the benchmark for comparison with nonlinear static analysis results. Considerable influences of different faulting mechanisms are observed on inelastic seismic demands. The demands are functions of the strength ratio and also the pulse period to structural period ratio. Simple mathematical expressions are developed to consider the effects of near-fault motion and fault type on nonlinear responses. Modifications are presented for the DCM by introducing a near-fault modification factor, $C_N$. In locations, where the fault type is known, the modifications proposed in this paper help to obtain a more precise estimate of seismic demands in structures.

In recent years, speedy development of Taiwan's hotel industry intensifies market competition, customers' demands on hotel services quality also increase with the increase of their consumption consciousness, and their demands on hotel types diversify, therefore hotel industry should concern on their unique management services quality brought by their different hotel types. The current designed service system or service transmission process may fail to meet customers' demands owing to emphasizing degree gap in service quality. What is worse, it is difficult for hotel industry to actualize complete customer segregation and to provide customized services, therefore comprehensive understanding of customers' demands on the service quality of different types hotels would contribute to operating management improvement of Taiwan hotel industry. This paper divides Taiwan hotels into three types: international tourism commercial type, holiday type and motel, the general hotels. It studies the emphasize degree gap in service quality between the industry and the customers. Data analysis shows that service quality gap (perceived gap) of hotels of different types exists in several quality aspects; what's more, the perceived gaps, service quality aspects, and its items of different types of hotel are also different. After an integrated analysis, this paper puts forward a general and customer-oriented quality item suitable for hotel industry to shorten the perceived gap of service quality, so that the hotel industry could design a service system and service transfer system, which could meet most lodging customers' demands in the context of pluralized customer sources.

Objective: The Job Demand & Resources model suggests work characteristics are related to mental well-being and work engagement. Previous work describes the development of a combined construct 'engaged well-being at work' (EWB). To what extent changes in measures of this construct are responsive to changes in job demands and resources or associated with changes in job-related attitudes has not been established. Methods: Longitudinal employee-level data from three waves (German Linked Personnel Panel) were used. Logistic and linear fixed effects regression analyses explored longitudinal associations between changes in EWB for participants over a three-year period with changes in job demands and resources and job-related attitudes (job commitment, satisfaction, and turnover intentions). Results: While job resources were associated with increased odds for a change into a healthier and/or more engaged category of EWB, job demands reduced them. Job resources were more strongly related to higher EWB (OR_range = 1.22 - 1.61) than job demands (OR_range = 0.79 - 0.96). Especially psychological job demands showed negative associations with improved EWB (OR = 0.79). A change from the least desirable category 'disengaged strain' to any other category of EWB was associated with greater odds by up to 20.6 % for increased commitment and job satisfaction and lower odds for turnover intentions. Discussion: Improving work characteristics, especially job resources, could increase employees' EWB, emphasizing the importance of job characteristics for a healthy workplace. Because EWB seems to be associated with job attitudes, an improvement of this indicator would be relevant for employees and employers.
