Over the last 10 years, the number of disasters has been increasing in Korea. As a result, the need for temporary residences or shelters for disaster conditions is increasing. In this study, post-disaster refugees housing was developed using lightweight composite panels that are lighter than the materials that make up the existing shelter. To accomplish this, the structural performance of the lightweight composite panel was validated. Among the performance tests on the panels, the transverse load test was conducted according to the ASTM E 72 criteria. As a result of the experiment, when each specimen was subjected to a uniformly distributed load, the allowable load was determined according to the span. All the experiments were ended due to a loss of adhesive at the junction of the skin and core. Further analysis was conducted to calculate the shear stress when the junction was dropped. The mean shear stress at the adhesive surface of a specimen, 150 mm and 200 mm in thickness, was 0.0170MPa and 0.0156MPa, respectively. This suggests that similar values were obtained from panels of equal thickness. In addition, this stress provides a criterion of judgment that could be used to inspect the structural performance of the panels. The performance of the panel was evaluated based on the allowable load, but it may be possible to increase the strength of the lightweight composite panel by improving the joining method to avoid separation from the junction.

Recently, vessel hijacking by pirates has been a big issue around the world. For example, the hostages of VLCC "SAMHO Dream" were released for a large sum of ransom. On January 20, 2011 "SAMHO Jewelry" succeeded releasing all of the 21 crews on the vessel by attacking the pirates in international waters for the first time since the founding of the Naval Force. Furthermore, the "HANJIN Tianjin" crews evacuated to the Citadel promptly and were rescued by the navy. As hijacking of Korean vessels by pirates is increasing, various safety measures must be implemented. As a matter of fact, the standard for ship's facilities has been partially revised and setting up an evacuation shelter on all vessels sailing dangerous zone has been reinforced. This research aims to discuss crew Citadel installation on vessels intended for long haul. In addition, it will look at measures against potential gas flow in the event of pirate armed attacks and fire outbreak onboard a vessel. It will also assess the optimal number of crew Citadels theoretically. Lastly, the optimal number of shelters in the event of fire outbreak will be discussed based on an FDS simulation.

1990년 이후 공산체계인 구소련과 동구권이 몰락하고 세계적으로 탈냉전의 변화와 우리의 민주정부 수립 후 햇빛정책 등에도 불구하고 북한은 적화통일을 포기하지 않고 작년 11월에 연평도에 포격을 가하여 민간인과, 군이 2명이 사망하는 사건이 발생 하였다. 또한 북한의 공격은 과거의 포탄공격뿐만 아니라 미사일이나 화생방과 같은 생화학물질 탑재 가능한 공격이 예상된다. 이에 대비 정부에서는 고정시설의 화생방 방호는 일단유사시에 국민의 생명과 재산을 보호하는데 필수요소로서 집단보호개념에 도입하고 있으며, 현재 각 중요 대피시설 및 지자체의 기존 대피시설을 개인방호, 탐지, 제독, 운용절차를 포함한 실태파악 및 재래식 탄을 포함한 통합적인 조치를 마련하고 있다. 작년 2010년 11월 연평도에서의 북한 포격이후 우리는 서해5도나 접경지역 주민과 그리고 근접거리의 서울시민들이 안전하게 포격으로부터 피난 할 수 있는 민방위대피소에 대한 문제점이 대두되고 대책방안을 요구하고 있다. 소방방재청 기준에 따르면 직격(直擊) 핵폭탄을 제외한 화생방, 재래식 무기 공격에 견딜 수 있는 시설은 '1등급 대피시설'인데 서울에는 한 곳도 없다. 고층건물의 지하 2층 이하나 지하철, 터널 같은 2등급 대피시설도 폭격은 견딜 수 있지만 화생방 공격에는 취약하다. 지하상가 등 건축물의 지하층, 지하차도나 보도는 그보다 더 취약한 3등급이며 단독 주택의 지하층처럼 방호 효과가 떨어지는 곳이 4등급이다. 2등급으로 분류된 대피소의 경우 분류만 되어 있을 뿐 장기간 대피시 시민들이 사용 할 수 있는 거주공간이 아닌 임시 대피로서의 역할만 하고 있다. 본 연구에서는 민방위 기본법에 따라 지하에 $3.3m^2$ 당 4명 이상이 대피할 수 있는 규모의 공간을 갖추기만 하면 대피시설로 볼 수 있는 현 문제점과 1등급에서 4등급으로 나뉘어져있는 민방위 대피소와 대피소가 있지만 피난공간으로서의 역할과 구조적으로 안전한가에 대한 국내외 실태 분석을 통하여 분석한 결과 우리는 서해5도 대피시설의 반 이상이 무용지물이고 접경지 또한 피난시에 피난장으로서의 대피소가 난방이나, 구급품과 식구 시설 등이 구비가 되어 있지 않고 대피시설로 지정한곳이 간판이나 안내시설이 없다. 외국의 경우 스위스는 연방정부의 관리책임으로 전쟁이나 핵 확산에 따른 화생방 업무 전담팀을 두고 있으며, 방독면은 개인 방호물자로서 전국민 100% 보유하고, 각가정이나 건축, 시설물의 경우 화생방 표준 대피시설 설치관련 규정 마련 시행하고 있다. 대피시설은 화생방 방호가 가능한 지휘부용 대피시설과 일반 주민대피용 시설을 구분하여 설치운영하고 있으며, 전국에 650만개를 설치하고 있다. 결론은 대피시설이 북한 공경시 피난시설로의 활용방안을 모색 등급구분에 따른 현실적용 수정과 기존 대피소 보강과 재선별이 필요하고, 신축시 설계 표준설계안 그리고 기존의 대피소에 대한 보수, 보강방법 가이드라인과 장기간 거주에 대한 설비구축 등과 국민 대홍보등을 제안하였다.

Korea has set up a radiation emergency planning zone based on the 「Act on Physical Protection and Radiological Emergency」 to protect residents living near nuclear power plants in the event of nuclear disasters. Little research has been conducted on the appropriateness of existing nuclear evacuation facilities because of a general lack of interest in nuclear accidents. This research addresses this gap by analyzing the location adequacy of evacuation facilities in Busan's emergency protection planning area based on vulnerable populations and accessibility analyses. The Gijang-gun which has the greatest risk, shows that only 4.05% of the total urban area was included in the evacuation service area within 5 minutes while only 36.93% of Geumjeong-gu and 37.23% of Haeundae-gu were included in the evacuation-enabled area. In addition, evaluation facilities in the elderly population hotspots were lacking, and there was a wide gap between dongs within the same Gu. Thus, additional evacuation facilities need to be designated and installed considering the spatial equity between areas and safety of both the public and vulnerable populations.

It is reported that abalone, Haliotis discus hannai, was detached from shelters by commercial oxytetracycline (OTC) dissolved in hydrochloric acid (HCl). In the present study, we investigated the exfoliation effect of fouling abalone by organic acids instead of OTC or HCl. Organic acids (malic acid, citric acid, lactic acid and formic acid) of pH 2.6 and pH 2.1-2.3 exfoliated over 67.6% and 91.7% of abalone, respectively; while OTC of pH 2.6 and pH 2.1-2.3 exfoliated 25.9% and over 74.1% of abalone, respectively. These results indicate that the exfoliation effect of organic acid is better than that of OTC dissolved in HCl at the same pH. However, a lower pH and longer treatment of organic acids resulted in delayed recovery of the detached abalone; abalone immersed in pH 2.3 for 10 second was recovered within 5 min, but took 12 min to recover after 30 second immersion. Moreover, recovery period for abalone exposed to pH 2.1 for 30 second was at least 15 min 45 second. In conclusion, though acids need to be cautiously handled, organic acids may be a better candidate to detach abalone instead of OTC or HCl.

This is a study that explores the influence of self-differentiation and acculturation among married immigrant women on their feelings of marriage satisfaction by residential area. The aim was to verify the level of self-differentiation and acculturation that married immigrant women secure from multicultural marriage. To achieve this objective, the study widely distributed a questionnaire that targeted women who were participating in education and other services at health and family support centers, multi-cultural family support centers, general social welfare centers, immigrant women shelters, and Korean language classrooms which are located in Seoul, Gyeonggi, Chungcheong, Jeolla, and Gyeongsang. Data analysis involved frequency analysis, descriptive statistics, one-way-Anova, and multiple regression analysis. Based on the results of descriptive statistics, two factors, namely, (1)interpersonal-relation differentiation, a sub-scale of self-differentiation, and (2)marginalization, a sub-scale of acculturation, had the lowest average. In verifying its various hypotheses, the study achieved the following results. Firstly, among demographic characteristics, there was difference of the mean in the marriage period, average monthly income, the frequency of meetings with the married woman´s parents-in-law and her own parents, and the average cost of supporting the woman's parents-in-law and her own parents. Secondly, among demographic characteristics, the variable of influencing marriage satisfaction showed negative influence in the case of women dwelling in farming and fishing villages. This shows that women residing in cities whether small, medium or large have higher marriage satisfaction. Also, as a result of verifying whether self-differentiation has influence on marriage satisfaction, the element of interpersonal-relations differentiation had a negative influence on marriage satisfaction. Thirdly, as for influence of acculturation upon marriage satisfaction, the study showed that just integration, which is a sub-scale of acculturation had positive effect on marriage satisfaction. In other words, the study showed that the interpersonal-relation differentiation among the sub-scales of self-differentiation among married immigrant women had a negative influence, and that integration among the sub-scales in acculturation had a positive influence on marriage satisfaction. Based on these results, in order to increase interpersonal-relation differentiation, as well as marriage satisfaction among immigrant women, the study suggests the integration of the women's families with the nuclear and extended families in the communities where the women reside.

The memory of the Korean War is about the time period when people lived toughly during evacuation, due to being exposed to the natural climate such as intense cold or heat without any protection, leaving their comfortable home and living in temporary built shelters which were barely enough to avoid the wind. 'Death is concealed and only the figures of evacuation for survival were expressed, just as how the government ordered. Since the experience of the battlefield is personal and fragmentary, that is broken into pieces, it does not have compatibility. As war is a distorted experience that cannot be placed in a big picture, it is not possible to take a view of the war's big picture. Having this individualized experience as a common collective memory is an issue and it is the will that people tries to pursue. The reason why the evacuees from north to south, and as well as from the south to further south were all able to be adopted as the theme of artworks due to the military action that emptied the occupied territories of the North Korean Army under the forced removal command. In such situations, the natural state of the 'snow' was like a symbol of the 1.4 Recession. The group of people who were thrown into the intense cold displaced the war damage of loosing their base livelihood, and symbolized the obedient citizens who faithfully follow their government's command. The figure of advocating anti-communism is projected as a figure of a refugee during cold winter-time and it contains ones past which he or she obeyed its own country's commands. Evacuation, especially the evacuation during the winter is a visual device that can confirm these kinds of country's command. The consequences were same for the artists as well. Therefore, the situation being communal could be found due to the individual experiences during war are ideological. The image of the refuge shown in the picture played the role of strengthening the consciousness of defecting to South Korea into the meaning of the 'Finding Freedom.' I would like to express that the reason of them leave their home during the harsh winter is in order to avoid the oppression of the Communist Party. The evacuation that people went through was not to 'Finding Freedom', but 'To Survive'. Later, this evacuation has been imprinted as a behavior of choosing free Republic of Korea, which was an ideological issue. Anti-communism was the rule of survival in South Korea society, and people have the tendency to remember what they want to remember. As it is not the people who possesses an incident, but the memory that possesses ones, people cover their memory with disguised plots in order to forget the violence and to live a different prologue. They share the incident of violence as a hurtful memory. The tragedy of the Korean War was the result of Ideology and being in between the powerful nations' rights, but the violence during the war has been depicted as a natural disaster, which was the evacuation in heavy snow.

Exfoliation of fouling abalone, Haliotis discus hannai from shelters by commercial oxytetracycline (OTC) was observed in culture farms. In the present study, different components of OTC for exfoliation of abalone were investigated to understand how to work. Abalone were detached from shelter in 14,000 ppm of commercial OTC (main ingredients of OTC: OTC-hydrogen chloride (HCl), 50%; glucose, 49%; blue pigment, <1%), but not below 8,000 ppm. A 95% of exfoliation rate was observed in OTC-HCl (7,000 ppm, pH 2.8) but no exfoliation in OTC-HCl (7,000 ppm, pH 5.0), glucose (7,000 ppm) or blue pigment (140 ppm). Moreover 100% exfoliation rate was observed in HCl-seawater of pH 2.8. These results indicate that HCl is the component resulting in exfoliation of the fouling abalone. Abalone was detached in HCl solution (pH 2.5-3.2) within 2 min. However, a lower pH and longer treatment resulted in delayed recovery of the detached abalone. Thus, exfoliation of fouling abalone can be achieved by a low pH treatment with cautious handling.

An earthquake of magnitude 5.4 occurred on November 15, 2017 in Pohang, which caused the damage to buildings and facilities. The earthquake displaced more than 1,700 people. After the Pohang Earthquake, immediate emergency, such as the damage survey and running of shelters have been executed appropriately. However there have been issues with subsequent restoration measures, such as the provision of temporary housing and delivery of natural disaster allowance. As there was inadequate government advertisement about the natural disaster allowance, victims of the earthquake could not receive tangible help. In Japan on the other hand where earthquakes are frequent, post-earthquake restoration protocols are planned well in advance. For example, Japanese earthquake victims are provided with a guidebook outlining different types of government aids available for them so that they can rapidly access government aid. In this study, we refer to the case of Pohang earthquake to analyse the problems in the national earthquake restoration plans and propose how they can be improved by comparing it to Japanese post-earthquake case and a Korean equivalent should be developed, to aid Korean earthquake victims to return to their every life as soon as possible.
