In this study, the National Disaster Management System (NDMS) was analyzed to evaluate the disaster impact assessment standards for steep slopes. Problems in the assessment methods and systems were discovered, which could be reasons for poor reliability. The disaster-risk evaluation index needs improvement to evaluate various types of retaining walls, such as concrete/reinforced soil walls and reinforcing stone masonry. Additionally, using the same score for overturning, bulging, and efflorescence could be reasons for poor reliability, and different weighting factors are needed. Assessment methods are needed to subdivide the social influence evaluation index while considering environmental conditions of steep slopes, such as railroads and reservoirs. For the evaluation of steep slopes, standards for start and end points of steep slopes should be created for effective management, and disaster impact assessment needs to be performed after redevelopment from an advanced index for protection and reinforcement. These problems were derived from a current evaluation system, so a disaster impact assessment is necessary to supplement the results of this study.

In this study, we introduce the French concept of 'valorisation' of heritage which corresponds to 'utilization(활용)' of heritage in Korea. As interests on the social, economic and identity values of heritage are increasing, it is considered as not only a target of protection and preservation but also an object of utilization. Even though this global transition has been formed quickly, the concepts regarding utilisation of heritage has not been academically founded and its related foreign terms or cases were not studied in depth. In particular, modern cultural heritage requires more attention and researches on the protection and utilization as it represents a relatively large range of utilization but it doesn't have strong protection policies. We justify the needs to introduce the concept 'valorisation' in Korea while analyzing Le Havre case that shows how to promote economic and social values of heritage as well as heritage values from 'local' to 'country' and to 'world'. This case was selected as it allows to identify the meaning of valorisation and heritagization process from modernly rebuilt areas after World War II to World Heritage Site.

An emergency generator is key equipment for fire-fighting to supply power to fire-fighting facilities, which protect property and people in cases of fire accidents. A rated load test for emergency generators must be carried out by connecting an emergency load to the generator in accordance with related regulations. However, a no-load test has been performed for emergency generators in general since serious problems can occur when the main power is cut off, including the damage of customer devices and shut down of critical loads. Therefore, this paper proposes a load test method for an emergency generator using energy storage system (ESS) without the interruption of main power. The emergency power system was also modeled based on PSCAD/EMTDC software, and a 200-kW scale ESS load test device was implemented. The simulation and test results show that the load test method is useful and practical for an emergency power supply system.

In order to infer whether the Special Act on the Punishment of Child Abuse Crimes, etc. actually brought about a change in the social perception shared about child abuse in our society, we used big data to examine the change in the perception of child abuse by the public. This study selected 'child abuse' as the keyword and collected and analyzed. The results of this study are as follows. First, before the implementation of the Special Act in 2013, the words "china" are kindergarten, teacher, body, problem, reporting obligation and neglect compared to the following. After the implementation of the special law, daycare centers, incidents, eradication, campaigns, domestic violence and preventive education were newly introduced. Second, the interconnection of key words in the previous picture of 2013 shows that the left group focuses on measures to introduce to prevent child abuse while the right group consists of keyword intended to view child abuse in conjunction with domestic violence. They are still seen as a group of divorces, discipline, neglect and parental education, which they still perceive as a family problem. Since the implementation of the Special Act in 2013, it will be divided into four groups, and the top group will be highlighted by the keyword related to child abuse cases, part of suspected cases and awareness of child abuse. In addition, the Act on the Special Cases of Child Abuse and the Child Protection Agency clearly appear as a child protection system.

As the interest in the positive quality of life is increasing throughout the world, the number of people who are suffering from negative sentiments, such as depression, anxiety, or stress, is increasing, as well. Especially, the adolescence period is the period of transition from childhood to adulthood and accompanies significant changes in terms of the body and mind alike. The purpose of this study is to examine the negative sentiment of the juveniles, caused by the stress they experience in their social and personal domains and the distress tolerance that can protect the inner feelings of them at the same time, to understand how they are related to the subjective well-being of the juveniles. For this study, the researcher employed the data from 362 high school students from the high schools located in Seoul and Gyeonggi area, which were analyzed using the statistics suites SPSS 22.0 and AMOS 22.0. According to the findings of this study, first, the depression and anxiety of the adolescent population showed a significant relationship for each variable with regard to the distress tolerance and the subjective well-being. Especially, the negative correlation with the subjective well-being was highly significant. Second, the depression and anxiety of the juveniles turned out to influence the distress tolerance and subjective well-being of them in a negative manner. In both distress tolerance and subjective well-being, the influence of anxiety was higher than that of depression. Third, in the relationship between depression, anxiety, and subjective well-being, the distress tolerance turned out to have a mediating effect. Such results of this study provided the basic data for suggesting the strategies to promote the perceived psychological well-being and help the juveniles who are under stress.

Korea, which became an aging society in 2000, has made transition to an aged society more quickly than expected since late 2017 after 17 years. Despite this trend, the awareness towards elderly housing facilities has not yet been raised across in society. The primary reason is that use of elderly housing facilities has not been promoted due to lack of understanding about the construction and management of the facilities. The housing of the elderly should be considered in terms of not only residential space but also the issues of medical care and continuous care. Therefore, the trend of elderly housing is pursuing the Continuing Care Retirement Community. Thus, this study analyzed the policies of existing elderly housing facilities and existing elderly housing through comparison with policies and housing of foreign countries. Based on the results, the the government intends to present characteristics and direction of suitable housing design of senior citizens' housing facilities through maintenance of UNIT, securing convergence through changes in the use of facilities, and realising the cost of operation, and studying social welfare measures to cope with the increasing number of elderly residents.

Purpose: This study intends to determine how disaster prevention characteristics of important state-designated wooden cultural properties in Gyeongsangnam-do vary according to the surrounding environments and to examine disaster prevention measures for wooden cultural properties that fit their surrounding environments accordingly. Method: The designation status and characteristics of cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do were identified, and the damage status of cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do was reviewed based on the history of disasters. Also, the disaster prevention environments for 58 state-designated wooden cultural properties in Gyeongsangnam-do and Gyeongsangbuk-do were analyzed separately into mountainous area, rural area and urban area, topographic characteristics were drawn. Results: For cultural properties located in urban areas, it was found that security guards were arranged properly and disaster prevention training was carried out well. In addition, access condition to the cultural properties was adequate; prompt access to such properties was possible. In rural areas, flame retardant works have been undertaken properly and many cultural properties were found to be located on a flat ground. Mountainous areas had highly inadequate access condition to cultural properties and disasters occurred most frequently in these areas in the past. Conclution: First, for wooden cultural properties located in urban areas, it is necessary to secure the self-defense fire service manpower for an initial response and reinforce the disaster prevention education. Second, for wooden cultural properties located in rural areas, prevention projects such as insect control project and disaster prevention insurance should be carried out in order to protect the cultural properties. Third, as for wooden cultural properties located in mountainous areas, it is necessary to prepare establish to reinforce self-response capability.

This study, as a purpose of base study for landscape redevelopement of Seowon, pointed out problems of planting patterns in each sector and suggested an alternative through analyzing old literature, complete enumeration survey in each sector and taking aerial images. the conclusions drawn from this study are as follows. A Pilam Seowon(historic site no 242) is located in a Pyungya-Sanrok(plain and mountain) district in Jangsung-gun and has Junhak-Humyo(Study room in the front and Shirne in the back) type. 23 taxonomic group of arbor, 6 taxonomic group of shrub and 5 taxonomic group of flowers are planted high-densitily in limited flat surface. It can be classified into being planted by family and being planted through landscape redevelopement in 1980s. Korean traditional trees are planted in this area like Pinus densiflora, Juniperus chinensis L., Thuja orientalis L., Zelkova serrato Makino, Sophora japonica L., Lagerstroemia indica, Prunus mume include Ginkgo biloba which is old big tree and is registered in Jangsung-gun as protected trees. The tea tree in this area was introduced from wild tea plantation in Yonhwa moutain and was planted. From now on, we have to pay consideration a form management of planted trees in the historical area, rearrangement of plant density due to over planting, removal of alien trees like Pinus bungeana and Canna generalisa, prevention a dwarfishness of main area due to over planting in outside facilities, recovery a alienation among each planting area, and planting concept from plants drawings on wall of buildings can be suggested. The implications of this case study is that introduction of over planting can make more problems like losing sense of place. Therefore, we must do a actual state survey on traditional landscape area like Seowon from preservation point of view.
