  • 최근 초대형화 되어 나타나고 있는 이상홍수와 지진 등에 의한 저수지 붕괴와 같은 대규모 비상상황 발생으로 하류지역 주민의 생명과 재산의 피해가 발생하고 있다. 국내의 경우 1996년 이후로 지속적으로 발생하고 있는 이상홍수로 인해 1998년에는 40개,1999년에는 5개의 소규모 저수지가 붕괴되었으며 최근 2013년과 2014년에도 저수지가 붕괴되는 상황이 발생했다. 댐붕괴의 원인은 구조물의 자연적 노화, 극심한 강우나 홍수, 지진, 제체전도, 파이핑, 침윤발생, 월류 및 파랑 등에 의한 자연적 상황 등이 요인이 될 수 있으며, 시공결함, 사고 또는 전쟁과 같은 인위적인 요인으로 발생할 수도 있다. 과거에 설계 및 시공기술이 부족하였거나 경제적인 이유로 부실하게 건설되어 있는 댐이 세계적으로 산재되어 있어 잠재적인 위험을 상당수 내재하고 있는 실정이다. 본연구는 댐의 점진적인 파괴에 의해 발생하는 유출수문곡선을 구하고 파괴의 성질을 예측 및 홍수파를 수리학적으로 추적하기위해 BREACH 모형과 DAMBRK 모형을 사용했으며 극한홍수(PMF)조건과와 최대지진발생(MCE)조건을 적용하여 원주시 관내 저수지 붕괴 모의 시나리오를 구축했다. 저수지 붕괴에 따른 유출수문곡선을 유도하기 위해서 본 연구에서는 기존의 EAP보고서 자료를 참고하여 붕괴지속시간, 붕괴부 평균폭, 붕괴부 측벽면 경사의 변화에 따라 다양한 모의를 수행함으로써 발생되는 붕괴부 유량 수문곡선을 도출하여 각각의 조건들이 붕괴파 형성에 미치는 영향에 대한 분석을 실시하였다. 그 결과 저수지의 붕괴시 첨두유출량에 민감한 영향을 주는 인자는 붕괴지속시간과, 붕괴부 평균폭으로서 이들 값이 붕괴유출량 변화에 많은 영향을 주는 것으로 나타났다. 최대지진발생(MCE)조건 해석결과 홍수류의 범람으로 인해 홍수파가 하류측으로 진행할수록 완만히 감소하며, 하천 중·상류부 인근 제내지로 홍수류의 범람이 발생하는 것으로 검토되었으며, 극한홍수(PMF)조건 해석결과 최대지진발생(MCE)조건과 같이 홍수파가 하류측으로 진행할수록 완만히 감소하는 특성을 보이며, 하천 전체 구간에서 인근제내지로 홍수류의 범람이 발생하는 것으로 검토되었다. 본 연구는 침수구역 피해규모 산정 및 비상대처계획도를 작성시 기초데이터가 되어 상황별 피해예상지역에 대해 응급행동요령, 주민대피계획비상대처계획을 수립하여 지역 주민생활에 안정을 기여하고자 한다.

  • The study sought to find out the actual process of adapting to social life through interviews with college students and adult women living as defectors in the South, and to find out how it would be desirable to move forward in terms of education in order for all of our lives to be happy. The method of research consisted of semi-structured interviews. The interview period was four months. Based on the results of the interview, the following conclusions are given. First, it is necessary to establish a direction for strengthening cooperation rather than conflict in education, and restoring homogeneity of the same people. It is also true that real challenges are not easy at a time when the fratricidal war like the 6.25 conflict has deepened the conflict. However, at this point, 65 years later, the nation cannot stay only in the past. Second, the perception that they disapprove of economic aid to North Korean defectors also exists in part among adults. Third, negative thoughts about reunification among South Koreans also appear relatively high. This is believed to be due to the argument that the growth of social welfare and economic growth is offset by the increase in unification costs. Fourth, the content of living in real life such as culture and art, along with knowledge-oriented education in school education, should be treated with the same weight. This should create an environment in which North Korean defectors can enjoy the same happiness as South Koreans.

  • This study is to carry out literary study about the subject of Martial Study in Song Dynasty which was in charge of military strategy education. Martial Examination and Martial Study were related to military officials in China, and also have important value of historical materials in physical education dealing with martial arts as traditional physical activity. To be a military official would be possible to correspond with such requirements as knowledge that sports experts should have, leadership as a leader, and ability reinforcement through physical training, and the effort to pass Martial examination as the chance of status rise contributed to developing sports and culture because the necessity of training military arts was emphasized in social situations. Martial Study establishment became a clue of creating and spreading the notion that General should have virtue and justice as an ideological style of new-Confucianism (neo-Confucianism and Sung Confucianism) in Song Dynasty. After founded in 1043 and equipped with a formal aspect in 1072, Martial Study got the political effect and improved national competitiveness while its function of cultivating and selecting excellent capable persons was going on smoothly. Educational contents in Martial Study were understanding and flexibly applying the skills of infantrymen, cavalrymen, and bowmen and the meanings and theories of confucian classics, testing problem solutions of reality, and teaching the measures of the problem. Martial Study included three aspects of military capable persons, war, and weapons and took charge of the function of education, selection, and promotion, steadily supporting development and continuance of Martial examination institution.

  • This study aims to explore the direction and tasks of Christian unification education as peace education. To this end, after examining the historical trend of peace education and unification education in Korea, the tasks of peaceful unification education are reviewed. Peace education has expanded with the activation of peace movements and educational discourse starting from civil society, while unification education has been planned in accordance with the government's unification and North Korea policy and is moving toward the field of education practice. However, due to the nature of unification education that aspires for peace, the combination of the two fields has continued steadily, and research on peace unification education has been continuously conducted. The direction and tasks of Christian unification education as peace education were proposed based on the tasks of peace unification education derived through prior research analysis and the trend of the times in the two areas to carry out the research purpose. For the sustainability of peace on the Korean Peninsula, Christian unification education as a peace education should aim to foster peaceful citizens who take the lead in transitioning from a culture of violence to a culture of peace. To this end, first, it is necessary to seek the direction of Christian education for the dissolution of the antagonist image. Second, activities that guarantee learners' subjectivity and autonomy should be carried out away from the top-down method in teaching and learning. Third, a curriculum connected to daily life should be formed.

  • Despite much discussions on cyber-terrorism in South Korea, several missing issues could be addressed. This paper attempts to deal with such missing but important issues. In South Korea, there has been little attentions on cyber-terrorism with the respects of national security strategy development under macro framework responding to future security environment. This article focuses on such issues. In other words, the purpose of this paper evaluates the meaning of national security threats raised from cyber-terrorism as a mode of security threats and proposes the matter of cyber-terrorism within the development of national security strategy in the future security environment. several issues in this discussion pass some important messages for the construction of national security strategic approach framework within the future security environment adding cyber-space. in the future environment, a new space called cyber is added as an important external condition which might determine the security of individuals, societies, and nations. Therefore, the fundamental strategic framework should be prepared. After that, the trend and direction of future technological advancement should be understood and the identity, nature, and types of threat should be analyzed. Also, after that, various responses and countermeasures are together constituted in the aspect of function and system regarding various anticipated threats of the future human society including cyber-terrorism.

  • The latest slogan put forth by the international space community is the safety, security, and sustainability of outer space activities. The security of outer space activities, in particular, would be defined as the secure state from space-based threats. The latter comprises passive threats (such as collision with other satellites and space debris) and aggressive threats (such as electromagnetic interference, arms race on the earth or in outer space, and military attacks). Has outer space been used for military purposes in practice? If so, does international law regulate the military space activities it? The use of outer space for military purposes is referred to as space militarization and space weaponisation. Satellites has been used in Gulf War, Kosovo War, and Afghan War, recently, and research and development on space weapons are under way. Since only the placement of weapons of mass destruction on orbit around the earth is prohibited in accordance with 1967 Outer Space Treaty, it may be asked whether other weapons may be placed on orbit. It will be necessary to analyze the stance of on the above question, by studying UN space-related treaties including UN Charter. New international space norms represented by PPWT, ICoC, and UN GGE Report are at the center of progressive development of international law. In conclusion, the author will signpost the various points on international norms to be codified on the use of outer space for military purposes.

  • Today each country in the world goes beyond the narrow concept of national security that was limited to national defense and ideology and are entering multi-dimensional global system mainly based on economic profits. Nevertheless, conflicts between nations due to religious and ideological reasons have brought unprecedentedly intense disputes Security services for head of states have been an important national mission in every era and society. However, they are becoming a main target for assassination and attacks by terrorists. Attacks on the head of state and other VIPs can cause aftermath ranging from war to conflict situation, political crisis, and economic loss. Therefore this study aims to draw insights by comparing protective security units of Korea, the U.S., and Japan which have different legal basis and sociocultural characteristics. Especially in South Korea, which faces difficult diplomatic stance due to the tension with North Korea and relationship with other countries such as the U.S., China, and Russia as well as polarization between classes, generations, regions, and ideologies, cohesion among members of society has weakened and hatred toward the head of state has been brought, which emphasizes the important of national security services. Therefore the study of protective security units and its operation by comparison between neighboring countries will be able to bring insights on the promotion of the security service.

  • In a recent period, it becomes more and more important to keep the cutting-edge industrial technology secured. This is because competitive technology appears to be a cornerstone of national power. Although the industrial espionage must be an illegal behavior or a kind of white-collar crime, there has been few researches on industrial espionage from a criminological perspective. This study investigates the relationship between industrial espionage, self-control, and organizational commitment. The hypotheses of this study were found to be statistically significant. The hypothesis 1 that the high self-control reduces the possibility of industrial espionage was accepted, and the hypothesis 2 that the high organizational commitment reduces the possibility of industrial espionage was also accepted. This results showed that self-control and organizational commitment were the key factors to prevent industrial espionage, which eventually reinforces industrial security. This study used a convenient sampling, which might be the limits of this study. By using a convenient sampling, the result of the study could not depend on representative sample. Nonetheless, this study was trying to explore the relationship between industrial espionage, self-control, and organizational commitment which was not researched yet. The purpose of this study is to contribute to find out the criminological causes of industrial espionage and eventually to prevent it.

  • 개념적으로 존재하던 클라우드 컴퓨팅의 사용이 본격적으로 심화되면서 기업들의 클라우드 컴퓨팅에 대한 개념과 생각에도 많은 변화가 생기게 되었다. 클라우드 컴퓨팅 구축이 더욱 가속화되는 가운데, 그로 인한 비용절감이나 투자수익 창출 효과에 대한 검증이 활발해질 것으로 예측됐다. 시대를 뒤바꾸는 혁신적인 기술도 잇달아 등장할 것이란 기대도 높다. 2013년은 클라우드 컴퓨팅의 발전에 또 한번의 변곡점이 될 것으로 전망된다. 본 고에서는 2013년 클라우드 컴퓨팅에 관한 예측 몇 가지를 살펴보고자 한다. 첫째, 중소기업에서의 클라우드 컴퓨팅 사용 및 정착이 가속화될 것으로 보인다. 대기업의 경우에는 기존에 구축되어 있는 IT 시스템에 대한 거버넌스 체계를 완성해 나가고 있는 상황 속에서 중앙집중형과 사용자 편의성이 강화된 클라우드 컴퓨팅을 도입하기 위해서는 아직 추구 해야 할 과제가 많다. 하지만 중소기업은 예산을 문제로 대기업과 같은 수준의 IT 인프라를 갖추지 못하고 있기 때문에 클라우드 컴퓨팅 도입으로 비용대비 고효율의 IT 인프라를 갖출 수 있다. 둘째, CSP, CSB와 통합허브가 성장할 것이다. 플랫폼 전쟁이 시장 점유율 '횡령' 싸움임을 CSP들이 깨닫게 됨에 따라 이러한 가격 경쟁들은 더 잦아질 것으로 전망된다. 그리고 2013년 클라우드 벤더들은 클라우드 가격 책정이 비용-수익 관리(costyield management)의 연장선에 있음도 알게 될 것이다. 핵심은 효율적 설계와 저비용 운영, 그리고 무엇보다 높은 사용률에 있다. 또한 기업들이 점점 많은 애플리케이션을 소프트웨어 형태로 구매하고 있기 때문에 애플리케이션 자체를 통합하는 문제, 애플리케이션에 대한 보안과 감사 프로세스개발 등의 문제가 제기되고 있다. 시스템 통합 서비스와 통합 허브는 이런 문제를 해결하기 위해 노력하게 될 것이다 셋째, 2013년은 하이브리드 클라우드 컴퓨팅이 급부상할 것으로 전망된다. 앞으로는 클라우드 컴퓨팅 시장에서 공급업체끼리 경쟁하는 것은 의미가 없으며 기업들은 절대 한 가지 클라우드 기술이나 공급자에 안주하지 않을 것이다. 이것은 곧 2013년에는 하이브리드 및 이종 클라우드 컴퓨팅이 각광 받을 것을 의미한다. 이러한 하이브리드 클라우드 컴퓨팅을 도입하기 위해서는 클라우드 컴퓨팅의 단점과 문제 해결을 위해 하나의 목적을 가지고 다양한 산업체들이 모여 경쟁업체이면서도 협력관계를 이루는 것이 중요하다. 넷째, 멀티 디바이스를 이용한 클라우드 사용이 폭발적으로 증가될 것으로 보인다. 1인당 여러 대의 단말 보유, 이동성 향상 요구, 4G 확산 등 모바일 시장을 중심으로 한 환경 변화로 인해 이전보다 한층 진화된 클라우드 기반의 서비스가 다양하게 등장할 것으로 예상된다. 또한 4G 시대가 본격적으로 개막되면서 데이터 및 앱을 저장하는 것뿐만 아니라 앱을 실행하는 프로세싱까지도 모두 인터넷 상의 서버에서 이루어지는 방식인 클라우드 스트리밍(Cloud Streaming)이라는 신기술이 상용화될 것으로 기대된다. 다섯째, 2013년에는 'XaaS(Everything as a Service)' 개념이 보다 확장될 것이다. 클라우드 컴퓨팅의 사용이 확산됨에 따라 하드웨어의 도입, 소프트웨어 및 데이터베이스 개발과 구축, IT 서비스 등 IT 인프라 스트럭처의 토대에 많은 변화가 생겼다. 인프라스트럭처는 더 이상 고정불변의 자산으로서가 아니라 유연성과 확장성을 강조하는 서비스로서의 특징으로 점점 부각되고 있다. 따라서 모든 IT 인프라스트럭처가 Ondemand화 서비스로 제공되는 비즈니스 모델들이 부상하고 있으며 플랫폼, 하드웨어 데이터베이스 등 모든 IT 요소를 서비스 형태로 제공하는 XaaS가 2013년 새로운 개념으로 떠오를 것으로 기대된다. 여섯번째로 스토리지를 둘러싼 가격 경쟁이 더욱 심화될 것으로 보인다. 업체들의 가격 인하는 앞으로도 계속될 것이며 사용자들에게도 큰 혜택으로 돌아갈 것이지만 사람들은 가격만으로 서비스를 선택하지 않을 것이기 때문에 가격보다는 차별화된 기능 및 서비스 전략이 필요할 것이다.

  • The 1920s and 1930s ushered in "the golden age" of Chinese comics when the comics flourished. Satirical cartoons in modern Chinese comics were popular due to emotional instability and war caused by foreign powers. Among many popular comics, this paper analyzes in the 1920s and in the 1930s which were made into films and dramas. Chapter Two shows that China in the Republican era of China expanded its consumer culture into some sectors like films, novels, magazines and fashion in the 1920s and 1930s. However, more than any other things, this chapter considers from the historical perspective "the golden age" of comics including comic magazine in the 1930s and a history of comic magazines that gained popularity with conventional and common story. Chapter Three explains that social satire cartoons were in vogue since the May Fourth Movement and anti-imperialistic and semi-feudalistic stories in the 1920s were realized in life. It also says that comics that describes the negative sides of its society were popular. Ye QianYu, a cartoonist, portrayed many facets of Shanghai through : the daily life of the middle and lower classes, bureaucratic corruption and sympathy for the working class. drawn by Zhang LePing describes the unfair social system between the bourgeoisie and the proletariat and the gap between the rich and poor through the main character, the powerless and poor orphan. and lampooned the reality of its time in an objective, witty and humorous way in terms of ethics and economy respectively. The researcher chooses to study and which are very familiar to us, because good cartoons, animations and movies stimulate the feelings about our surroundings.
