N, N-Diethyl-N-methacryIoyloxyethy1amn;onium chloride(DAMA), quaternary ammonium salt of 2-diethylaminoethylmethacrylate, was prepared Then P(DAMA) was obtained by polymerization of the DAMA. P(DAMA-co-MAA) was also obtained by copolymerization of the DAMA and MAA(N-methylolacrylamide). Antistatic agents, PDA and PDAC, were prepared by purity control to P(DAMA) and P (DAMA-co-MAA), respectively. PDA and PDAC were treated on PET textiles with and without resin. Then surface electric resistance and half life characteristics value were tested. As the results, there were no remarkable decreasing changes in antistatic abilities of the textiles treated with PDAC-2 and PDAC-4 after 30 times washing. So PDAC-2 and PDAC-4 were proved to be durable anbstatic agents. Surface electric resistance of the textiles treated with PDAC-2 and PDAC-4 before washing were iX 10 7$\Omega$ and 2 X 10 7$\Omega$, respectively, and half life characteristics values were 0.9 sec and 12 sec, respectively.

The outflow of young people from the provinces due to the concentration of Seoul metropolitan area is accelerating. Although the government has introduced numerous policies focusing on job creation and housing, the actual problems remain unresolved. There is a need to research examining who the young people settled in the region are, and why they are staying in this area. The research aims to identify the factors that enable certain young people to continue their activities in the region through a case study of ‘PAN’ cooperative in Chuncheon-si, Gangwon-do, analyze how this cooperative is addressing the issues and present policy alternatives. The findings are as follows: First, young people have chosen a self-directed life path by regaining their self-esteem through active extracurricular activities in their universities. The convergence of economic reasons, competitiveness in the region, and the pursuit of a different life style from urban areas has led these young people to decide to settle in the region. Second, they have created job opportunities for themselves in the region by starting businesses based on the trust that naturally developed through their long-term activities. The implications of the research are that positive experiences and social relationships in the local community have become one of the factors influencing the decision to settle in the region, and that even if good job opportunities are not available, the possibility of choosing the area increases when other factors are met.

최근 발생하는 자연 재난 중 홍수피해는 여름철에 집중되면서 태풍 장마로 인해 인명 피해나 재산피해로 이어진다. 이러한 피해를 줄이기 위해 많은 연구가 진행되고 있다. 본 논문에서는 이러한 돌발홍수 발생 시 최단 거리 알고리즘을 사용하여 경로를 검출하고 사용자에게 제공하는 시스템을 설계하고 구현한다. 제안하는 시스템은 QGIS를 사용하여 트랙과 포인터를 생성한 지형 데이터를 활용하여 경로를 검출한다. 또한 시나리오를 통하여 검출된 경로로 대피하는 과정에서 돌발홍수가 발생 시 다른 최단 경로를 검출하여 사용자에게 제공한다. 따라서 사용자는 제안하는 시스템을 통하여 향후 발생하는 재난 안전 사고 위험에 안전한 대피를 할 수 있을 것으로 사료한다. Among the recent natural disasters, flood damage is concentrated in the summer, leading to casualties or property damage due to the typhoon’s rainy season. Much research is being done to reduce this damage. In this paper, we design and implement a system that detects paths and provides them to users using shortest-distance algorithms in the event of such sudden flooding. The proposed system uses QGIS to detect paths using topographical data that generated tracks and pointers. In addition, other shortest paths are detected and provided to users when sudden flooding occurs during evacuation to routes detected through scenarios. Therefore, it is assumed that the proposed system will allow users to safely evacuate from the risk of future disaster safety accidents.
Research on responsible parties for shootings in the United States

미국의 총기소지권은 헌법의 규정에 따라 미국국민에게 부여한 권리이다. 총격사건이 빈번히 발생함에 따라 총기소지권이 합법화한 배경 하에 미국사회는 총기관리에 관한 곤경에 처해있다. 이에 많은 학자들이 대상문제에 대한 심도 깊은 연구가 진행되었음에도 불구하고 총격사건 이후의 책임부담에 관한 문제의 논의는 아직까지 그 상황에 맞게 부각되지 않았다. 본 문에서는 현행 미국의 총기관리제도에 입각하여 총격사건의 책임주체를 명확하게 구분하였으며, 본 문에서 나열한 책임주체로는 크게 정부, 총기양도인(매도인 및 제조상), 사고지역(지점)관리자와 총기소지자(총격자)로 한정 하였다. 총격사고 책임문제에 관한 연구의 결과로는 첫째, 정부의 보상계획을 보완하고; 둘째, 총기제조상과 매도상의 총격사고에 관한 전문배상(보상)기금을 설립하고; 셋째, 총기양도 관련 법적규제를 보완 및 강화하고; 넷째, 사고지역 관리자의 합리적인 보장의무를 부여하여야 한다는 제안을 하였다. Gun rights are the constitutional rights that the US constitution allows American citizens to hold a gun. However, frequent occurrence of shootings reveals the dilemmas of gun controls under the background of the legalization of gun rights in American society. Many expects have studied further in this hot-bottom issue but none have referred to who should bear the responsibilities of the shootings. On the basis of the existing gun law, this article divides the responsible parties of the shootings, which are government, gun"s transferors, site managers and gun holders, and finally puts forward some suggestions on perfecting government compensation plan, setting up special funds on gun manufacturers and sellers, improving the laws of transferring guns and defining the reasonable safeguard obligation of the site manager.
