The importance of seismic design is greatly emphasized recently in Korea, resulting in an increase in the number of dynamic analysis being performed. One of the most important input parameters for the dynamic seismic analysis is input ground motion. However, it is common practice to use recorded motions from U.S. or Japan without considering the seismic environment of Korea or synthetic motions generated in the frequency domain. The recorded motions are not suitable for the seismic environment of Korea since the variation in the duration and energy with the earthquake magnitude cannot be considered. The artificial motions generated in frequency domain used to generated design response spectrum compatible ground motion has the problem of generating motions that have different frequency characteristics compared to real recordings. In this study, an algorithm that generates target response spectrum compatible ground motions in time domain is used to generate a suite of input ground motions. The generated motions are shown to preserve the non-stationary characteristics of the real ground motion and at the same, almost perfectly match the design response spectrum.

This study empirically analyzes the policy demand for population inflow in Hongcheon-gun, a region that has experienced population decline over the past decade. The results of this study based on the multinominal logit model provide the policy implications as follows. First, due to the differing factors influencing the demand for population inflow policies among the young and the elderly, local governments should clearly define the policy targets for population inflow. Second, in the context of policy demand for population inflow through corporate attraction, we identify statistically significant and positive effects of the length of residence for both young and old people, and the level of formal education for the elderly. These results emphasize the importance of formulating population inflow policies distinctively targeted for the young and the elderly generations, respectively, thereby increasing population inflow in the population reduction area.

The purpose of this study is to develop hybrid energy blocks with piezoelectric and electromagnetic induction method. The developed energy block is able to be applied to the housing and facilities in the city and is suitable to adjust the characteristics of facilities. To develop the hybrid energy block, we analyzed the characteristics and requirements of various energy block types and drew improvement and application method to develop energy blocks. We compared and analyzed the characteristics and performance of the prototype energy blocks and the developed hybrid energy blocks. According to result of the comparison and analysis, the developed energy block shows higher performance of 12.7 times for adding one vibration and 28.9 times for five consecutive vibrations than that of a existing prototype energy block. This is consistent with research purposes for W-level electrical energy production. Thus, the new energy block will likely be possible to apply to the housing and urban facility.

Most existing residential environment of disabled people has made them exposed to the risk of safety accidents, and therefore hinders their independent living. In this regard, the importance of desirable residential environment has emerged. Some preceding studies have addressed the characteristics of disabled people's residential environment plan; however, the information on what environmental benefits are offered through such characteristics is insufficient. This study aims to analyze the housing design guidelines for disabled people in respect of the benefit of disabled people who are actual users. In this study, essential design guidelines for disabled people verified through expert workshop panel was analyzed based on user benefit theory. According to the study results, the total guidelines have the most characteristics supporting behavioral facilitation, and mainly consist of physiological maintenance characteristics related to disabled people's health and safety. Also, it is founded that environmental affordance essentially required depending on each spatial function was different. The ratio of physiological maintenance item is high in access route, unlike living room, kitchen and bed room where behavioral facilitation is especially emphasized. These findings can be utilized as basic data for customized residential environment plan to realize residential welfare for disabled people.

The aim of this study is to empirically identify the differentiating characteristics of determinant factors on sing-person households' commuting mode choice compared to multi-person households' one in order to establish the customized police directions to decrease private car use in commuting. While the study use the 2% sample survey data on the population and housing in 2015, it employ multinomial logit models on relative choice probability of such alternative commuting modes as bus, subway or rail, and walking, rather than driving. As potential determinant factors, the study employs demographic, socio-economic, and housing and residential one for both models of single-person and multi-person households. The study finds that the behavior of commuting mode choice has distinctive difference by gender, marriage status, physical activity constraint, job type, residential period in current housing of the single-person household's workers compared to the multi-person households' ones. Based on the findings, the study deduce ten commuting policy directions customized for the single-person household.

Using youth panel data, this study attempted to diagnose the effect of residential characteristics (housing type and housing type) and various household background variables on the implementation of youth NEET (Not in Employment, Education or Training), and to suggest appropriate policy directions. As a result of the analysis, it was found that young individuals residing in unfavorable living conditions such as those who rent on a monthly basis or live in multi-household, villa, or officetel settings, had a higher likelihood of transitioning to NEET. Those who received financial support from their parents were more likely to transition to NEET. Therefore, comprehensive youth NEET support policies such as customized housing and job policies according to the characteristics of NEET should be established. In particular, even though they have reached adulthood, it is shown that the likelihood of becoming NEET is very high for youth who live together with their parents without being economically independent or who receive financial assistance from their parents. In order to mitigate and prevent these young people from NEET transition, transitioning from school to the labor market should be facilitated with policy support.
