The wall painting and Relief type sculpture were a part of an architecture. Therefore they had better to be preserved in situ, differing with other works of arts. But we confronted inevitable cases to transfer them in appropriate place to conserve. And considering their fragility and a potential danger such as a vibration and shock in process of transfer, we had to do the preventive treatments to prohibit unexpected deteriorations. In this paper, I mention the transferring process when Kwon's 'Relief' was faced to be removed by reconstruction program. A preventive treatment and packaging method were referred in priority.

오는 4월 13일은 임시정부수립기념일이다. 이에 상하이의 인쇄사에서 잠시 근무했던 이봉창 의사와 독립선언서를 인쇄했던 보성사에 대해 알아본다. 이봉창 선생은 1932년 1월 8일 일본제국주의의 심장부인 도쿄에서 삼엄한 경호를 받으며 궁성으로 돌아가던 일왕에게 수류탄을 투척, 일본인의 간담을 서늘케 하고 전 세계 피압박 민족에게 큰 충격을 준 인물이다. 이 선생이 터뜨린 한발의 수류탄은 당시 침체일로에 있던 상해임시정부에 새로운 전기를 마련해 주었다. 정부는 지난 62년 선생의 장거를 기리어 건국훈장 대통령장을 추서했다. 보성사터 기념비는 지금의 조계사 좌측 수송소공원에 있는데, 천도교에서 경영하던 인쇄사로 보성학교 뒷마당에 자리 잡고 있었다. 1919년 당신 최남선이 경영하던 신문관과 함께 최대 인쇄사로 꼽혔다. 보성사는 1919년 6월 28일 일본의 방화로 추정되는 화재로 전소됐다.

This study was conducted to identify acculturative stress in foreign workers in Korea. The data of 123 subjects were collected from January to May, 2010, and analyzed using the SPSS WIN 18.0 program to compare demographic characteristics and acculturative stress. The results: The highest score among 7 subcategories of acculturative stress was homesickness, followed by discrimination. Subjects who had high school diploma were more likely to have acculturative stress than those who were middle school graduates or lower. Those who did not have the community with their homeland people experienced acculurative stress more than those who had. The 7 subcategories showed that those who had homesickness, the sense of being discriminated, culture shock, the homeland community, and the experience of unfair treatment in public had acculturative stress more than their counterparts. Those who did not live with their spouses had homesickness more than the counterpart. Male subjects, those with high school diploma, and those who did not live with their spouses appeared to have guilty feelings more often than their counterparts. The results of this study suggested further studies on foreign workers so that they could adjust themselves well to the Korean society.

Decay or large cavities inside trees are the main causes of trees overturning and broken branches, and structurally weakened trees are more vulnerable to strong winds and heavy snowfall. Recently, as strong winds and typhoons increase due to climate change, the damage to human life and property due to trees overturning continues to increase, and cultural assets are in a similar situation. In particular, old big trees are structurally vulnerable to external shocks such as strong winds and heavy snowfall. This study was aimed at providing a scientific basis for preventive protection measures by conducting a structural stability diagnosis of seven retusa fringe trees designated as natural monuments. For the structural stability diagnosis, tree risk assessment and internal tree defect measurements were performed. As a result of the tree risk assessment, the Retusa Fringe Trees in Sinjeon-ri, Yangsan and Gwangyangeupsu had the highest risk of broken branches due to weak branch attachment strength. As a result of the diagnosis of internal defects of cross sections of measured trees, there were suspected cavities or severe decay in all except two trees of the population of Retusa Fringe Trees in Pyeongji-ri. Natural disasters due to climate change are increasing, and the scale is getting larger, so it is very important to preemptively manage large old trees through scientific structural safety diagnosis to manage trees that are vulnerable to environmental changes.

The purpose of this study was to analyze the life experiences of fifteen marriage immigrant Asian women who went through running away from their home countries, marrying with Korean men, divorcing from their husbands, and coping with many difficulties after their divorce in Korean society. In order to conduct this study grounded theory methods have been employed. The central phenomenon digged out from this study was 'resistance to baffled reality' (i. e. dislocation). The causal conditions which brought about the central phenomenon were 'escaping for survival' and 'experiencing the gap between reality and expectation. 'The intervening conditions included 'getting to know the reality of their husbands,' 'losing hope,' and 'not being able to pull themselves together.' The contextual conditions consisted of 'being treated as maids,' 'becoming victims of family violence,' 'making up their minds to survive,' 'securing future life,' 'being marginalized,' and 'being aware of themselves as strangers.' The action/interaction strategies on the central phenomenon were 'building support systems,' 'building up will for new life,' and 'reconstructing social identity.'The final outcome was 'arranging places of new settlement.' The divorce was classified as four types: 'coping and growth,' 'emancipation and settling down,' 'being overwhelmed by livelihood,' and 'continuous wandering.' Based on these results, this study provided a few political and practice suggestions to prevent family violence and divorces among multi-cultural families, and also to bumper the impacts of divorce.

COVID-19 is hitting the world. In order to bring about new ways of innovation in the space sector, we need to analyze changes in the space sector and design new challenge strategies. COVID-19 exposes inherent vulnerabilities in the space sector. In particular, COVID-19 is causing supply chain shocks in the space industry, resulting in delays in the supply of systems, subsystems and parts due to a complete or partial interruption of a manufacturing unit. As the overall impact of New Normal on the industry is overall, we continue to look at it in the space sector. COVID is causing supply chain shock in the space industry. It causes a delay in the supply of systems, subsystems and parts due to a complete or partial interruption of a manufacturing unit. In the supply of launch services, the launch schedule is being delayed, but the main launch is still taking place. Demand for major applications such as environmental monitoring is soaring in the earth observation utilization sector. Analyzing the impact on manufacturing, the vendor-based contraction is bringing delays in the supply of systems, subsystems and components, and launch service providers are trying to minimize delays in the launch schedule.

Host rock of Cheonjeon-ri petroglyph is shale belonging to the Daegu Formation of Cretaceous Gyeongsang Supergroup. The rocks were hornfelsified by thermal alteration, and shows high density and hardness. The petroglyph forms weathered zone with certain depth, and has difference in mineral and chemical composition from the unweathered zone. As the physical deterioration evaluations, most of cracks on the surface appear parallel to the bedding, and are concentrated in the upper part with relatively low density. Breakout parts are occurred in the upper and lower parts of the petroglyph, accounting for 6.0% of the total area and occurs to have been created by the wedging action of cracks crossing. The first exfoliation parts occupying the surface were 23.8% of the total area, the second exfoliations covered with 9.3%, and the exfoliation parts with three or more times were calculated as 3.4%. It is interpreted that this is not due to natural weathering, and the thermal shock caused by the cremation custom here in the past. As the ultrasonic properties, the petroglyph indicates highly strength in the horizontal direction parallel to bedding, and the area with little physical damage recorded mean of 4,684 m/s, but the area with severe cracks and exfoliations showed difference from 2,597 to 3,382 m/s on average. Physical deterioration to the Cheonjeon-ri petroglyph occurred to influence by repeated weathering, which caused the rock surface to become more severe than the inside and the binding force of minerals to weaken. Therefore, it can be understood that when greater stress occurs in the weathered zone than in the unweathered zone, the relatively weathered surface loses its support and exfoliation occurs.

The urban railway sleeper floating track, the subject of this study, is an anti-vibration track to reduce vibration transmitted to the structure. currently, the replacement cycle of resilience pad for sleeper floating tracks is set and operated based on load. however, most previous studies were conducted on load-based structural safety aspects, such as fatigue life evaluation of sleeper anti-vibration pads and increase in track impact coefficient and track support stiffness due to increase in spring stiffness. therefore, in this study, we measure the vibration acceleration of the ballast for each analysis section and use the results of 7 million fatigue tests to calculate the spring stiffness of the resilience pad for each section. the spring stiffness of the resilience pad calculated for each section was set as the analysis data and the concrete vibration acceleration was derived analytically. the adequacy of analysis modeling was verified as the analyzed concrete bed vibration acceleration for each section was within the field-measured concrete bed vibration acceleration range. using the vibration acceleration curve according to the derived spring stiffness change, the spring stiffness of the resilience pad is estimated from the measured vibration acceleration. therefore, we would like to present a technique that can estimate the spring stiffness of resilience pad of a running track using the vibration acceleration of the measured concrete bed.

Specific techniques and materials in conservation of traditional lacquer has not been transmitted. This study aims to compare the basic characteristics of the filler which used in the base layer of lacquer conservation. Tohoe(a mixture of lacquer and Clay) and the three kinds of additives which is mixed with Tohoe and Goksu(a mixture of lacquer, wood powder and rice starch) are estimated in drying rate, impact resistance, abrasion. Among those samples, the more amount of clay causes fast dryness speed and worse cracks on the surface. The impact resistance is weakened at high amount of clay. There is no significant differences of impact resistance between both additives that is mixed with the samples and additives. The samples that are mixed with Goksu and additives show high impact resistance. In the polishing test, the more amount of filling powders show higher grinding degree and the sample that are mixed with wood powder and charcoal show higher degree as well. The highest grinding degree is Maekchil and Goksu but the lowest one is the sample of the rooftile powder mixture.
