As the terrorist act inflicted on the American Ambassador to Korea, Mark Lippert on March 5, 2015, the hunting rifle case in Sejong-si in which 3 persons were killed on February 25, and the hunting rifle murder case in Hwaseong-si Namyang-dong on February 27 occurred in succession, there is growing concern that our country is no long safe from firearm violence. Internationally, there is growing concern that our country is no longer safe from international terrorist organizations such as Islamic State (IS), the Sunni Muslims fundamentalists' Islamic militia group, which an 18-year old Korean boy Kim voluntarily joined in January 2015. The police crisis negotiation of our country was established and operated to prepare for the 1988 Olympic Games mainly for counter-terrorism purposes, and due to the characteristics of the prohibition of the use of guns, not a counter-terrorism incident has occurred, so the skepticism about its existence and the development directions are actively being discussed. Our country still prefers the traditional use of force such as SWAT team to resolve crisis case, such as such as murder, terrorism, robbery, and is reinforcing tactical capabilities. However, to perform the primary mission of the police to protect the people's lives and properties, it is necessary to establish the system in which crisis negotiations are possible in the initial stages no matter what incidents may occur by expanding the education for crisis negotiations techniques which are emphasized in the advanced countries such as the United States. In this research, the police department's internal education materials and media are analyzed so that the new police officers who work hardest on the forefront can carry out the roles as basic negotiators of crisis negotiations, and the measures for the development directions of the police crisis negotiations are presented.

The police is responsible for protecting nation's property and life. Protecting nation from crime among the core duties is the most important activity of the police. But the big problem on reported crime system of the police was founded in the recent Suwon incident. Unfortunately, the unprofessional response made a toll of human sacrifice. Taking this opportunity, we need to consider closely the problems of the reported crime and system of the police and the solutions on the problems. This study analyzes the reported crime system of the police from the law and institutional and try to seek the solutions. This study searches the management status of the police system and arranges the problems in legal and institutional terms. And then, it arranges the solutions on the problems.

연명의료결정법의 정식 명칭은 '호스피스 완화의료 및 임종 과정에 있는 환자의 연명의료 결정에 관한 법'이다. 이 법은 호스피스 완화의료에 대한 것과 환자의 연명의료 결정에 대한 것을 규정하고 있다. 특히, 후자의 연명의료결정에 관한 부분은 법제정 과정에서 법 종교 의료 윤리 등 다양한 분야에서 논박이 있었지만 2018년 2월 4일부터 시행되고 있다. 법학에서는 이 법이 생명이라는 법익과 관련되어 있어 형사법적, 민사법적으로 중요한 의미를 갖는다. 이 법이 탄생되기 위해 두 번의 변곡점이 있었다. 첫째, 1997년 '보라매병원 사건'에서 의사를 작위에 의한 살인방조죄로 판결한 사건 둘째, 2009년 '김 할머니' 사건에서 회생할 수 없을 경우 가족 등이 진술한 환자 의사에 따라 연명 의료를 중단할 수 있다는 대법원 판결이다. 연명의료결정법은 헌법상 생명권과 자기운명결정권이라는 기본권 충돌이 발생한다. 두 기본권이 서로 상충 할 때에는 어떠한 기본권을 우선해야 하는지가 실질적으로 문제되는데, 이익형량을 통한 규범의 조화로운 해석을 통해 해결해야 한다. 또한 이 법의 흠결과 문제점을 고찰하여 개정작업이 진행되어야 한다.

The law enforcement agencies in the worldwide are confiscating or retaining computer systems involved in a crime/civil case, if there are any, at the preliminary investigation stage, even though the case does not involve a cyber-crime. They are collecting digital evidences from the suspects's systems and using them in the essential investigation procedure. It requires much time, though, to collect, duplicate and analyze disk images in general crime cases, especially in cases in which rapid response must be taken such as kidnapping and murder cases. The enterprise forensics, moreover, it is impossible to acquire and duplicate hard disk drives in mass storage server, database server and cloud environments. Therefore, it is efficient and effective to selectively collect only traces of the behavior of the user activities on operating systems or particular files in focus of triage investigation. On the other hand, if we acquire essential digital evidences from target computer, it is not forensically sound to collect just files. We need to use standard digital evidence container from various sources to prove integrity and probative of evidence. In this article, we describe a new digital evidence container, we called Xebeg, which is easily able to preserve collected digital evidences selectively for using general technology such as XML and PKZIP compression technology, which is satisfied with generality, integrity, unification, scalability and security.

The Serial murder is a serious social phenomenon that gives a shock to community and society, because of it's habituate and scheme. We could identify a happening of serial killing crime at Western society, especially in U. S, but hardly to find many cases in Korea except some of cases. We can easily prospect the happening of serial killing crime at Korea in the future, at least it exists that home and social disorganization cause by divorcing and hasty economic development. There will be a reserve criminal who have distorted personality effected by undesirable surrounding, therefore he may become a serial murder. This study examines criminal psychological analysis of On Bo Hwan's serial murder case in 1994 at Korea, according to criminal records and press report and his statement and confession. This paper also show his domestic background and growing atmosphere and human relation between his parents.

본 현대사회는 문명적, 기술적, 산업적으로 발전함에 따라 그에 상응하는 절도, 폭행, 살인 등 중대범죄의 범위를 벗어나 이념과 국가, 종교, 등 가치관과 사상에 따른 테러 사건 등 국제적인 범죄도 증가하고 있는 추세이며, 국제사회는 중대범죄 및 전쟁의 공포보다 예측 불가능, 막대한 대량 피해를 불러오는 테러에 의한 공포심을 더 비중 있게 대하는 현실에 직면했다. 테러범죄는 개인을 넘어 다중에게 피해를 입힐 수 있는 범죄인만큼 대중에게 경각심과 위험성을 알리기 위해선 구체적이고 손쉽게 이해할 수 있는 명확성이 필요하다. 테러는 수년간 다양한 방식과 개념들이 증식했으며 피해 또한 더 이상 소규모인원, 특정인을 향한 계획적인 범행에서 불특정 다수를 향한 뉴테러리즘식의 테러로 발전하고 있어 안보의 개념에도 영향을 미치고 있다. 따라서 대한민국 역시 언제까지나 테러의 위험성으로부터 안전을 확신할 수 없기 때문에 국내 정서에 맞는 테러 대응방안과 시스템 구축을 통해 뉴테러리즘의 발생 가능성을 염두 하고 대비할 필요가있다.

In this paper, we study an algorithm that automatically determines the orders of past observations and conditional mean values that play an important role in count time series models. Based on the orders of the ARIMA model, the algorithm constitutes the order candidates group for time series generalized linear models and selects the final model based on information criterion among the combinations of the order candidates group. To evaluate the proposed algorithm, we perform small simulations and empirical analysis according to underlying models and time series as well as compare forecasting performances with the ARIMA model. The results of the comparison confirm that the time series generalized linear model offers better performance than the ARIMA model for the count time series analysis. In addition, the empirical analysis shows better performance in mid and long term forecasting than the ARIMA model.

Hwaseong serial murders are not now having any significant concern either with Hwaseong City or Dongtan New Town, a region in Hwaseong City, both spatial and temporal manners. However, despite that, people have come to see Hwaseong City with negative ideas as the mass media drove the people to do so. In this study, how films and newspaper articles have created those negative images of Hwaseong City was investigated and afterwards, residents and students living in Dongtan New Town had interviews on what they think about the negative regional images. The study, then, worked on a mental map and others based on what it learned from the interviews. Regional identity confusion is now being discovered out of the people's resistance against the negative images of the city and through such research process described before, the study discussed this regional identity confusion caused by living as residents in Hwaseong and living as residents in Dongtan New Town. In addition, the study revealed sense of place of Dongtan New Town and aspects of the regional identity confusion with this Dongtan New Town growing both with symbolic meanings as a place of murders, an awful crime, and spatial meanings as another place of dynamic developments and improvements.
