핵물질 불법거래에 의해 제기되는 가장 큰 문제는 국제 핵확산 금지의 체계를 파괴하여 핵 위협을 가중시키는 것이며, 핵물질에 이해가 없는 사람에 의한 운반이나 보관 등의 책임에 의하여 방사선 방어상의 문제점을 일으킬 수 있다는 것이다. 최근에 급증하고 있는 핵물질 불법거래는 핵물질 확산금지에 커다란 문제를 야기하고 있다. 우리나라도 핵물질 불법거래 발생의 가능성이 있음을 인식해야 하며, 이에 대한 국가적 대책을 마련하여야 한다.

When illegal transactions are made with bitcoin, it's not easy to track all the bitcoins used in the transaction and seize them. Especially, if criminals distribute illegal transactions by spreading them to several bitcoin addresses, it's difficult to track hidden bitcoins other than confiscated bitcoins even if some bitcoins are confiscated. This paper proposes a method for tracking and monitoring all bitcoin transactions suspected of illegal transactions. This method estimates bitcoin addresses that are highly relevant to crime among all bitcoin addresses that dealing with the address based on the bitcoin address list of the alleged crime, and keeps track of addresses that are relevant to crime and help to investigate illegal bitcoin transaction.

문화생활을 즐기는 현대인의 증가와 함께 온라인 티켓 거래가 활발하게 이뤄지고 있다. 문화생활에 대한 수요가 증가하고, 온라인을 통한 티켓 거래가 활발해지는 만큼 불법 거래 사례와 피해 또한 커지고 있다. 이러한 불법 거래 방지를 위해 본 논문에서는 기존 모바일 티켓팅 시스템의 QR코드에 티켓 고유식별번호와 난수를 결합하고, 사용자의 지문 인식과 사용 시간 제한 등의 기능을 추가한 불법 거래 방지 티켓팅 시스템을 제안한다.

This paper examines the pecuniary effects stemming from insider trading in the equities of firms targeted for acquisition. Illegal exchanges by those having advantageous information are found to result in excessive returns to stockholders of the sought firms. However, unusual market activities are not typical immediately subsequent to the illegal trading date, suggesting that nonpublic information is synthesized by market mechanisms with sufficient speed so that others cannot profit by imitating the better informed traders. The obtained evidence does not support the contention that insider trading on nonpublic information harms the outsider stockholders of involved firms.

석유제품은 고율의 세금(특소세 및 교통세) 부과와 소비자나 거래자가 품질ㆍ상표ㆍ계량을 확인하기 어려운 특성을 갖고 있으며, 그 결과 탈세ㆍ무자료 거래 등 불법ㆍ부정유통의 가능성이 매우 크고, 실제로 이 같은 불법ㆍ부정유통이 시장에서 빈번히 발생되고 있다는 지적이 있어왔다. 특히, 1995년이후 석유산업의 전반적인 자유화 및 규제완화 추세에 따라 이동차량을 이용한 무자료 거래와 일부 수입사의 부당영업행위 등 불법ㆍ부정유통의 규모가 커지고 있다는 우려가 제기되어 왔다. 이에 따라 산자부는 2002년 5월이후 연구용역과 관련업계 및 전문가의 광범위한 의견수렴을 거쳐 이번 개선방안을 마련하였다. 2002. 12. 11(수) 규제개혁위원회 경제1분과위원회의 심의를 마쳤으며, 향후 필요한 절차를 거쳐 내년 상반기내 석유사업법령 개정을 추진, 빠른시일내 시행할 예정이다. 산자부는 이번 「석유유통구조 개선방안」과 별도로 『유류구매카드제』 도입을 추진, 정유사ㆍ수입사ㆍ대리점ㆍ주유소ㆍ판매소 및 직매처(대수요처)간의 거래를 카드로 결제하고, 그 내용이 석유공사의 석유수급전산망에 자동입력되게 하여, 석유제품거래의 투명성과 유통의 건전성을 근본적으로 제고할 계획이다.

관세법에서는 해외직구물품이 일정금액(미화 150불, 단 미국은 미화 200불)이하 또는 자기사용 물품으로 인정되는 경우에 제세를 면제토록 규정하고 있으며 관련규정을 어길시 관세법상 무신고 밀수입죄에 해당된다. 본 논문은 해외직구 리셀러(되팔이)가 증가하고 해당 사항이 사회적 이슈로 대두되기에 해외직구 물품 불법거래에 관한 모니터링시스템을 설계하고 해석하였다. 온라인 중고 사이트(e-commerce)에서 거래되고 있는 거래 내용을 크롤링을 통하여 데이터를 수집·전처리를 통해 구조화하고 데이터 정제, 텍스트 범주화, 텍스트 마이닝 등 관계 예측을 해석하였다.

International circulation of cultural assets involves numerous countries thereby making an approach based on international law essential to resolving this problem. Since the end of the $2^{nd}$ World War, as the value of cultural assets evolved from material value to moral and ethical values, with emphasis on establishing national identities, newly independent nations and former colonial states took issue with ownership of cultural assets which led to the need for international cooperation and statutory provisions for the return of cultural assets. UNESCO's 1954 "Convention for the Protection of Cultural Property in the Event of Armed Conflict" as preparatory measures for the protection of cultural assets, the 1970 "Convention on the Means of Prohibiting and Preventing the Illicit Import and Transfer of Ownership of Cultural Property" to regulate transfer of cultural assets, and the 1995 "Unidroit Convention on Stolen or Illegally Exported Cultural Objects" which required the return of illegally acquired cultural property are examples of international agreements established on illegal transfers of cultural assets. In addition, the UN agency UNESCO established the Division of Cultural Heritage to oversee cultural assets related matters, and the UN since its 1973 resolution 3187, has continued to demonstrate interest in protection of cultural assets. The resolution 3187 affirms the return of cultural assets to the country of origin, advises on preventing illegal transfers of works of art and cultural assets, advises cataloguing cultural assets within the respective countries and, conclusively, recommends becoming a member of UNESCO, composing a forum for international cooperation. Differences in defining cultural assets pose a limitation on international agreements. While the 1954 Convention states that cultural assets are not limited to movable property and includes immovable property, the 1970 Convention's objective of 'Prohibiting and preventing the illicit import, export and transfer of ownership of cultural property' effectively limits the subject to tangible movable cultural property. The 1995 Convention also has tangible movable cultural property as its subject. On this point, the two conventions demonstrate distinction from the 1954 Convention and the 1972 Convention that focuses on immovable cultural property and natural property. The disparity in defining cultural property is due to the object and purpose of the convention and does not reflect an inherent divergence. In the case of Korea, beginning with the 1866 French invasion, 36 years of Japanese colonial rule, military rule and period of economic development caused outflow of numerous cultural assets to foreign countries. Of course, it is neither possible nor necessary to have all of these cultural properties returned, but among those that have significant value in establishing cultural and historical identity or those that have been taken symbolically as a demonstration of occupational rule can cause issues in their return. In these cases, the 1954 Convention and the ratification of the first legislation must be actively considered. In the return of cultural property, if the illicit acquisition is the core issue, it is a simple matter of following the international accords, while if it rises to the level of diplomatic discussions, it will become a political issue. In that case, the country requesting the return must convince the counterpart country. Realizing a response to the earnest need for preventing illicit trading of cultural assets will require extensive national and civic societal efforts in the East Asian area to overcome its current deficiencies. The most effective way to prevent illicit trading of cultural property is rapid circulation of information between Interpol member countries, which will require development of an internet based communication system as well as more effective deployment of legislation to prevent trading of illicitly acquired cultural property, subscription to international conventions and cataloguing collections.

조달청이 입찰자 정보를 분석해 불법전자입찰을 색출해내는 '불법전자입찰 징후분석시스템'을 본격 가동한다. 조달청(청장 권태균)은 지난 7월 22일 "아직도 일부 입찰자들이 전자입찰시스템을 악용, 담함 및 공인 인증서 대여 등의 불법입찰 행위를 하고 있다"고 지적하고 "이를 체계적이고 상시 감시하기 위한 불법전자 입찰 징후분석시스템(이하 '징후분석시스템')을 본격 가동해 불법입찰 혐의가 짙은 201개 업체를 공정거래 위원회에 조사요청 할 계획"이라고 밝혔다. 이번 '징후분석시스템'의 본격가동으로 인증서 대여를 통한 불법전자입찰 행위를 뿌리 뽑아, 국가예산의 낭비방지 및 공공공사와 조달물품의 품질 제고에 기여할 것으로 기대된다.

In this paper, we propose a monitoring system for illegal overseas direct purchase based on C2C transaction between individuals. The Customs Act stipulates that direct purchases from overseas are exempted from taxation only if they are less than a certain amount (US$150, but US$200 in the US) or are recognized as self-used goods. The act of reselling overseas direct purchase items purchased with exemption from taxation online, etc., is a crime of smuggling without a report. Nevertheless, the number of re-sells on online second-hand websites is increasing, and it is becoming a controversial social issue of continuous violation of the Customs Act. Therefore, this study collects unspecified transaction details related to overseas direct purchase, refines the data in a big data method, and designs it as a monitoring system through natural language processing, etc. analyzed. It will be possible to use it to crack down on illegal transactions of overseas direct purchase goods.
