Integrated management of Korea national and environmental planing for sustainable development is suggested, and basic research is needed. In this study, national and regional plans were assessed using 'integrated management index of Korea national planning and environmental planning' to grasp the current status of integrated management on Korea national planning and environmental planning. As a result of the assessment, it was found that both national and regional plans need to improve considering the natural ecology part and water resource and quality part. In addition, it was derived that the detailed contents of the indicator can not be reflected according to the characteristics in the higher-level plan. Therefore, it has been found necessary to include proclamatory contents so as to be able to establish a detailed plan that reflects environmental goals in the lower-level plan.

The knowledge about drought propagation is very important in accurate estimation of hydrological drought characteristics and efficient development of early warning system. This study investigated a probabilistic relationship of drought propagation based on Bayesian network model for historic period and for future projection under climate change scenario RCP 8.5 over the Han River basin. The results revealed that the propagation rate and lag time have increasing and decreasing trends from the historic period of 1967-2013 to the future periods of 2014-2053 and 2054-2100 under climate change, respectively. The probabilistic results of Bayesian model revealed that the probability of occurrence of lag time varied spatially and decreased when the intensity of meteorological drought changed from moderate to severe and extreme condition during 1967-2013. The values of probability increased in the first future period of 2014-2053 in several sub-basins and slight decreased in the second period of 2054-2100. The proposed probabilistic results will be useful for the decision makers to develop related policies with an appropriate insight toward the future drought status.

A bake-out process using auto switchgear for five days was performed to evaluate the reduction effect of the concentration of volatile organic compounds (VOCs) and formaldehyde in a newly-built elementary school gymnasium. Reduction rates of VOCs were observed as followings: 38.2, 64.2, 86.3, 80.2, and 71.5% for benzene, toluene, ethylbenzene, xylene, and styrene, respectively, which satisfies the indoor air quality standards of newly-built apartment houses in Korea. The reduction rate of total VOCs and formaldehyde were 67.0 and 24.7%, respectively. Those results proved that the bake-out process using auto switchgear was effective for reducing indoor air pollutants.

This study explores fire prevention measures for single-person households on the phenomenon of an increase in single-person households due to changes in the family structure due to low birthrate and aging population, full marriage, non-marriage, separation, bereavement, and returning to farming villages, and increased flexibility in the labor market. The factor that affects the fire of single-person households is the residential environment problem at the structural level. In terms of behavior, there is an increase in fire occurrence due to the rearing of companion animals. In order to prevent fires in single-person households, safety regulations without exceptions are needed to improve the residential environment at the structural level. At the behavioral level, it is necessary to expand the prevention and safety guidance of related organizations. In addition, as a measure to prevent fire caused by companion animals, manufacturers of electric ranges should develop safety devices to prevent fires caused by companion animals, such as an automatic power-off device or power supply using a timer. It can also be an important means to create and distribute promotional videos of measures necessary to safely raise companion animals, or to develop and distribute disaster preparedness programs implemented in virtual reality.

This study aims to understand the community sense and need for community programs for large scale cooperative rental housing residents, and to set the direction of the construction plan. To this end, a survey was conducted on visitors and contractors of the model house in Westaybyeolnae. As a result of the analysis, the most visitors to the model house were in their 20s and 30s, while the number of contractors in their 30s was the most. Most of the model house visitors currently do not participate in community activities, but the contractors wanted to interact with neighbors about once a week. The contractors had high demands for sports facilities and child-rearing facilities, and the most demanded for living cooperatives and child care services. However, the range of neighbors required by age, the degree of meeting, common facilities and programs required were different.

Since the village maintenance type public housing project was introduced in 2015, the resident needs for regional revitalization and pleasant living conditions are not being met due to the poor performance of the public housing complexes that reflect the surrounding area maintenance plan (village plan) and regional characteristics. The purpose of this study is to suggest a plan to revitalize the village maintenance type public housing project in consideration of regional characteristics as a result of analyzing the needs of local residents through the problems of the village maintenance type public housing project being promoted so far and resident satisfaction. As a result of the analysis based on the public housing project implementation status analysis and resident satisfaction, the plans to activate the village maintenance type public housing project are as follows. First, in order to secure the effectiveness of the village plan, it is desirable to promote the public housing project and the village plan at the same time. It is necessary to secure a budget according to the selection of public offering projects in the village plan, such as promoting public housing projects without setbacks by prioritizing land purchases for public housing sites and establishing specialized strategies considering regional characteristics. Second, a public housing project that responds to local demand is required. The evaluation factors such as continuous promotion of the urban architecture integration plan and strengthening of regional linkage plans such as specialization of regionally tailored designs should be supplemented so that regional resources and village plans are linked with the public housing specialization plan. Third, surrounding area maintenance plan (village plan) should be secured by the strengthen of the legal status or establishing related provisions. It is also necessary to promote system improvement for area maintenance plan (village plan) when selecting a publicly funded public project.

In this study, we analyzed the current situation of court libraries and aimed to propose a future-oriented strategy for preserving and managing their collections. Based on literature and status analysis, the study presents the future preservation strategy of court library collections in three main categories: First, securing space for the long-term preservation of court library collections; second, establishing a system for collecting and preserving court library collections; and third, performing digital archiving for the permanent preservation and utilization of court records, valuable legal volumes, administrative materials, and other judiciary-specific resources. Through this, court libraries, including those in various courts, should resolve the issue of insufficient collection storage space, preserve holdings systematically and efficiently, and activate library use.
