This study was to develop the indicators for understanding social inclusion exclusion of the dwellers living in permanent rental apartment, and to present a important base about priority order of national housing policy for social inclusion. The ultimate purpose of this study was to provide basic information for the development of permanent rental apartment renewal techniques. The first phase of the study was to review of the social inclusion exclusion indicators mentioned in the literature. The indicators of EU (2001, 2006), KIHASA (2005), and Jehoel-Gijsbers & Brooman (2007), which were applied in many studies about social inclusion, or included various items about dwellers' subjective attitudes, were selected to construct the framework for the study. On the basis of 3 kinds of indicators at the above, the dimensions of social inclusion exclusion were categorized as material deprivation and access to social rights in an economicstructural exclusion view, and social participation and cultural normative accommodations in a socio-cultural exclusion view. And then, the domains of social inclusion exclusion were decided as follows: income, employment, education service, housing, health, family networks and social networks. The detail contents of indicators were adopted from the prior studies as many as possible, and the dwellers' subjective attitudes and housing domains were intensified with reference to UN housing rights and the study of "residents' satisfaction of housing facilities living in permanent rental housing". The developed indicators were modified through the advisory committee that consist of the specialists from the various fields of studies. The final indicators that were overlapped or not able to be measured were eliminated, and added, in a housing domain, the standards of convenient facilities, the management condition, safety, location, crime and etc. in the apartment complex, which were required to complement in the advisory committee.

Agricultural drought is a natural phenomenon that is not easy to observe and predict and is difficult to quantify. In South Korea, the amount of agricultural water used is large and the types of use are varied, so even if an agricultural drought occurs due to insufficient precipitation, the drought actually felt in the irrigated area is it can be temporally and spatially different. In order to interpret the general drought in the past, drought disasters were evaluated using single indicators such as drought damage area, precipitation shortage status, and drought index, and a comprehensive drought management system is needed through drought diagnosis survey. Therefore, we intend to conduct research on agricultural drought assessment and diagnosis using re-evaluation of agricultural facilities and irrigation water supply network due to changes in various conditions such as climate change, irrigation canal network, and evaluation of water supply capacity of agricultural facilities. In this study, agricultural drought diagnosis was conducted on two agricultural reservoirs located in Sangju, Gyeongsangbuk-do, with structural or non-structural evaluations to increase spatiotemporal water supply and efficiency in terms of water shortages. The results of the agricultural drought diagnosis evaluation can be used to identify irrigated areas and canal network vulnerable to drought and to prioritize drought response.

Background: This study aimed to develop and assess the psychometric features of the Physical Activity at Workplace Questionnaire (PAWPQ) based on the Social Cognitive Theory (SCT) to evaluate employees' physical activity (PA) behaviors at the workplace. Methods: This psychometric cross-sectional study was conducted on 455 employees working in one of the gas refineries in Iran. The participants were selected using the proportional stratified sampling method in 2019. The data collection tools were a demographic information questionnaire, the short form of the International Physical Activity Questionnaire (IPAQ), and a questionnaire developed based on the SCT, whose psychometric features were confirmed in terms of validity and reliability. Data were analyzed using SPSS₂₂ and AMOS₂₀ software. Results: The first version of PAWPQ-SCT had 74 items. After evaluating content and face validity, nine items were removed. The results of the content validity index (0.98), content validity ratio (0.86), and impact score (3.62) were acceptable for the whole instrument. In exploratory factor analysis, after removing seven items-58-item final version of the scale-six factors could explain 73.54% of the total variance. The results of structural equation modeling showed the acceptable fit of the model into the data (RMSEA = 0.052, CFI = 0.917, NFI = 0.878, TLI = 0.905, IFI = 0.917, CMIN/DF = 2.818). Cronbach's alpha coefficient and Intraclass Correlation were 0.90 and 0.86, respectively. Conclusion: This study confirmed that the psychometric features of the 58-item final version of PAWPQSCT constructs were acceptable in a sample of Iranian employees. This questionnaire can be used as a valid and reliable tool to evaluate Iranian employees' PA behaviors and develop effective educational interventions for workers and managers.

연구목적: 최근 대형 사회재난이 발생하면서 사회재난 안전도 진단에 대한 필요성이 요구되며 행정안전부에서 지역 안전지수, 국가안전대진단 등 지역의 안전도 등급을 계산하여 매년 공표하고 있다. 기존의 안전도 진단 시스템은 등간격 혹은 정규분포를 이용해서 획일화된 방법으로 등급화를 진행하여 위험지도를 작성하고 있다. 연구방법: 하지만 등간격 기법은 위험등급을 객관적으로 분석할 수 있지만 분포가 한쪽에 치우쳐있는 경우 위험등급을 분류하는데 한계가 있으며 z-score 기법은 모집단이 정규분포를 따르지 않으면 신뢰도가 떨어지는 문제가 있다. 지표별로 통계 데이터의 분포가 상이하기 때문에 데이터 분포별로 가장 적합한 등급화를 적용해야한다. 연구결과: 따라서 본 논문에서는 재난 지표의 데이터를 분석하여 각 지표마다 최적화된 등급화를 진행하고자 기존의 등간격 기법과 네츄럴브레이크 기법을 비교 및 적합한 방법을 제시하였다. 결론: 그 결과 기존의 등급화 기법과 다르게 적용된 것은 6새 지표 중 3개에 해당하였다.

With the rapid development of highways and railways, series of traffic safety issues emerged because of mudstone disintegration. To research on the mechanism and further guarantee the stability and safety of transportation infrastructure built on or near mudstone formations, the mudstone disintegration test of mudstone was carried out based on mudstone and sandy mudstone. The element types, cementation characteristics and pore characteristics of the tested specimens were studied by means of Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and Image Pro Plus (IPP). The disintegration index of mudstone was approximately 1%, and even some specimens were difficult to be calculated, while the disintegration index of sandy mudstone is approximately 8.7%. According to the results, the two mudstones belong to grade II and III disintegration respectively, of which the sandy stone presents more extensive disintegration than mudstone. This phenomenon was distinguished that, the clay minerals of mudstone are approximately 25% more abundant than those of sandy mudstone, and the unit pore area is 20 ㎛² larger, which result in different microstructure and water absorption capacities. In the liquid phase, the ions in the mudstone specimens were exchanged and combined with water molecules in the environment during the whole disintegration process. This results in continuous spalling and fragmentation of clay minerals, the emergence of secondary fractures, and the deepening of primary fractures.

기존의 연구논문들에서는 1975년부터 1992년 사이의 OECD 국가들에서 집권정부별 국민들이 느끼는 행복감을 알아보기 위한 분석들이 주로 이루어졌다. 이러한 행복감을 알아보는 데에는 특히 인플레이션율과 실업률이 주요 변수로 활용되고 있다. 각국별로 살펴볼 때, 진보정부의 경우에 있어서는 실업률에 더 주안점을 두는 반면에 보수정부 는 인플레이션율에 더 민감하게 대처함을 알 수 있었다. 이러한 점들을 살펴보면, OECD 국가들에서 빈곤층은 진보정부를 선호하고 상대적으로 소득수준에서 상위계층 은 보수정부를 선호할 것으로 추정된다. 이 논문에서는 한국의 경우 시계열 관계상 진 보정부와 보수정부로 나누지 않고 행복감에 대하여 소비자심리지수를 대용변수로 사 용하였을 경우 경기회복에 따른 산업생산 증가와 이를 위한 정부지출이 중요한 변수 임을 알 수 있었다.

In this study, the library ESG evaluation indicators specialized for libraries were developed, and based on which, a survey was conducted targeting the actual libraries to evaluate the ESG level of libraries. As a result of the study, first, among the ESG evaluation indicators, the indicators of the social field and the governance field are demonstrating high in which field of the library's ESG evaluation indicators will appear the highest. The social area's high score of 3.70 seems to be because the protection of users' rights, occupational safety, and contribution to society and the local community are very closely related to the original role of the library. Second, it may be seen that there is a difference between the questions in the corporate governance part, while the averages are the same. In the case of library's cooperation, it turned out that it was 3.94 in the necessity evaluation of the evaluation indicators, but it was lowered to 3.61 in the actual library situation evaluation. Meanwhile, in connection with the activities of the director of library and the board of directors, it may be seen that the index evaluation increased from 3.32 to 3.58 in the actual evaluation.

This study proposes a fast estimation method of dynamic reliability indices or failure probability for SDOF structure subjected to earthquake excitations. The proposed estimation method attempts to derive coefficient function for correcting dynamic effects from static reliability analysis in order to estimate the dynamic reliability analysis results. For this purpose, a total of 60 cases of structures with various characteristics of natural frequency and damping ratio under various allowable limits were taken into account, and various types of approximation coefficient functions were considered as potential candidate models for dynamic effect correction. Each reliability index was computed by directly performing static and dynamic reliability analyses for the given 60 cases, and nonlinear curve fittings for potential candidate models were performed from the computed reliability index data. Then, the optimal estimation model was determined by evaluating the accuracy of the dynamic reliability analysis results estimated from each candidate model. Additional static and dynamic reliability analyses were performed for new models with different characteristics of natural frequency, damping ratio and allowable limit. From these results, the accuracy and numerical efficiency of the optimal estimation model were compared with the dynamic reliability analysis results. As a result, it was confirmed that the proposed model can be a very efficient tool of the dynamic reliability estimation for seismically excited SDOF structure since it can provide very fast and accurate reliability analysis results.
