The liberated korea has the estimated population 16 million in 1945, and added 2.5 million just after an year. The korean repatriates returned by way of 2 main routes. The returnees, Wol-Nam-Min(former residents in north korea), and repatriates from Manchuria came into south korea over the 38th division line. The other repatriates from japanese islands and pacific areas came into Busan port and the vicinity. The repatriates who returned from the China and the Japanese islands made up about 80% of the total added population. However, the influx of overseas repatriates who explosively increased between 1945 and 1946, declined abruptly in April of 1946, and at last illegal re-emigration group to Manchuria and Japan Appeared, who had repatriated from those areas. This study deals with the "re-migration phenomenon of 1946" in korea, mainly focuses on 1) the motivation for those who decided to remigrate, their prospects of resettlement in Manchuria and post war japan after re-migration, 2) the structural problems of the Korean society in 1946-1947, and 3) the social recognition for the people who letf for Manchuria and Japan. This study proved the cause and background of re-migration phenomenon. The Manchuria case, the local authorities wanted farmers and peasants who could cultivate the abandoned land which had been originally pioneered and reclaimed by korean poor peasants, who repatriated to korean peninsula. On the other hand, the korean repatriates had a hard time in tenanting farmland, and so much difficulty in getting farming tools including fertilizer. That's why they left korea for Manchuria again. The Japanese case, the korean repatriates had a tough life owing to the restriction of properties left in japan, while the inflation and food shortage in korea got worse and worst. Accordingly, many koreans tried illegal entrance into post war japan. This study is a part of clarifying the universality and specificity of post war repatriation and migration issues developed in the south Korea. Through this study, we can find how difficult it is for newly liberated areas to accommodate repatriates and make them ordinary nationals in harmonic way with successful social integration. and we can observe the social aspect and administrative ability of newly liberated south korea in detail, Because the present korea has faced with so many problems connected with immigration workers and re-setting with korean communities abroad, we should introspect these historical experience of our own.

근래 통신과 인터넷과 디지털 및 그래픽 기술의 발전으로 콘텐츠 산업은 새로운 문화 창달 및 경제발전의 중요한 산업으로 부각되고 있다. 디지털 콘텐츠 기술의 발전은 콘텐츠의 생성 및 유통을 획기적으로 발전시켜 새로운 부가가치를 창출하며 거대한 유통시장으로 확대되었다. 그렇지만 디지털 기술의 특징 중 하나인 유통과 복제가 용이하다는 것은 무단으로 불법복제와 도용, 변조로 인한 불법콘텐츠의 유통량도 증대 시켰으며 이로 인한 피해도 심각한 실정이다. 현재 온라인사이트를 대상으로 하는 저작권 보호 제도는 있지만 정작 온라인에 밀려 고전하고 있는 오프라인 정품 콘텐츠를 판매하는 업체를 대상으로 시행되는 제도는 부재하다. 한류열풍 등으로 해외 관광객의 콘텐츠 수요가 급증하고 있으나 오프라인 정품 콘텐츠 업체들은 온라인 업체들과 불법콘텐츠 유통으로 상당수가 경쟁력을 잃은 상황이다. 이에 본 연구에서는 선행연구를 통해 국내와 해외의 유사한 저작권 인증제도의 사례와 현황을 분석하고 인증제도의 요인들을 도출하여 이를 기반으로 오프라인 정품 콘텐츠업를 인증해 주는 제도에 대해서 연구하였다. 사례분석과 함께 저작권 관계자들과의 심층면접을 통해 얻은 인터뷰 내용을 중점으로 정품 콘텐츠 판매 오프라인 업체 인증제도의 인증영역, 인증 방향성, 인센티브를 정하여 인증제도 프레임워크를 도출하였다. 도출된 인증방향은 윤리형, 개방형, 당락형, 매장인증형, 다소엄격형(사후평가)의 인증모델을 선택하였다. 본 연구를 통해 국내 소비자들의 정품 콘텐츠 사용인식 확산과 건전한 콘텐츠 시장의 투명한 거래질서 확립을 기대해 본다.

Tigers are the large cats with prominent, black or brawn, stripes. They are common in jungles of India and Java, but range as far as the snowy, forested mountains of Siberia. Legal and illegal killing(over-hunting, poaching for skin, and also its bones, f

Due to a number of illegal copied videos, many video content markets have been threatened. Since this copied videos have intercepted the profits of the content holders, content developers lose the will to generate new contents. Therefore, video copy detection approaches have been developed to protect the copyrights of video contents. However, many illegal uploader who generate copied videos used video transformations to avoid video copy detection systems. Among of the video transformations, rotation and flipping did not distorted the quality of video contents. Thus, these two video transformations were adopt to generate copied video. In order to detect rotated or flipping copy videos, rotation and flipping robust region binary pattern (RFR) recently was proposed. But, this RFR has a weakness according to rotated angles. Therefore, in order to overcome this problem, multi region binary patterns are proposed in this paper. The proposed method has the similar performance with the original RFR. But, it showed much higher efficiency for memory spaces.

고도의 정보화 사회에서 데이터의 내용변경, 중요한 데이터의 불법적인 유출, 순 서 변경 그리고 미확인 송신자와 수신자등에 의하여 항상 위협을 받음으로써 데이터의 안전성이 요구되고 있다. 본 연구에서는 컴퓨터 통신의 안전을 위한 다변수 Knapsack 암호시스템을 제안하였다. 이 시스템은 기존의 Knapsack 암호시스템보다도 간단하면서 높은 안전성을 갖는다. 그리고 제안된 암호 시스템은 초증가벡터의 각 요소를 변형하 여 다변수 다항식으로 표현한 것을 암호벡터로 구성한다. 암호문의 복호는 비밀의 정 수와 초증가벡터를 사용하면 평문의 구해진다. 따라서 이 암호의 안전성은 비밀의 정 수를 다변수 다항식으로 나타내는 암호벡터에 대입할 때 암호벡터가 초증가벡터로 되 는 근을 구하는 것의 어려움에 근거하고 있다. 제안된 다변수 Knapsack 암호시스템의 타당성이 컴퓨터 시뮬레이션을 통하여 입증되었다.

컨테이너 보안 장치(CSD)는 컨테이너의 문 안에 장착되어 센서를 통해 컨테이너의 문이 비정상적으로 열리는 것을 탐지하는 장치다. 이러한 CSD 장치는 컨테이너의 보안성을 제공하는 장치이기 때문에 도청이나 위조와 같은 공격에 안전해야할 뿐만 아니라 복제 되어서도 안된다. 만약 복제된 CSD를 탐지할 수 없다면, CSD는 공격자에 의해 불법적으로 복제되어 정상적인 목적과는 다른 용도로 사용되어 질 수 있다. 본 논문에서는 이러한 복제된 CSD를 탐지하기 위한 정책 기반 복제 탐지 메커니즘을 제안한다. 또한 실제 구현 결과를 통해 제안하는 기법을 검증 및 평가한다.

With rapid changes taking place in every field, the expansion and specialization of various social service activities are one of the characteristics of the modem society. However, the increase of crimes and inefficiency of public police service to cope with this situation have caused discontent and distrust on the service among the public, making people more inclined to solve safety-related problems by themselves. Private Security Service(PSS) and Private Investigation Service(PIS) were introduced to satisfy these needs. In the area of PIS, Public Investigation Service System(PISS) has been established for a quite long time in foreign countries. However in Korea, PIS is being provided by unregulated service providers such as errand service center due to the lack of legal system, causing many problems related with illegal practices by the service providers. This paper is the result of the research on how to adopt a relevant PISS in Korea and develop it in the future. This kind of research is much needed to curb the rising illegal practices of the errand service centers, complement the insufficient operation of public police service, and strengthen the competitiveness of our country by taking more efficient actions in the changing public security environment. Based on the research, this paper also examines positively the possibility of introduction of PIS in Korea. This paper also recommends a prompt enactment of PIS regulation and improvement on the legal environment for such introduction of the relevant and suitable PISS in Korea.
