As modern society has become specialised and complex in all areas of politics, economy and society, it has reached a point where it is difficult to control crime with the general public power. Private security, which began to fluctuate after the 19th century, has expanded its scope to subsidise public power in various areas, sometimes beyond public power. Among these private security activities, the private investigate system has long been used to provide private investigate services that are safe from personal human rights protection and crimes. This study investigate the private investigation system in the United Kingdom and South Korea focusing on the missing person investigation system by using the qualitative content analysis of research methods. First, the results of the qualitative content analysis are described through methods such as literature reviews and interviews on how the British private investigation system and the missing persons search system are implemented. Next, the results of the content analysis are presented through the methods of literature reviews and questionnaires on how the implementation of the civilian survey in Korea and the search for missing people is proceeding. It is a very important field in both countries, and there is a very limited study, especially from a Korean perspective. Therefore, it is expected that this study will not only facilitate discussions for the successful legalisation of the private research system, but also provides a basic foundation for future research. The study of the private research system should be ongoing and periodic, not temporary. In addition, in order to introduce Korea's private survey system, the private investigation system should be developed by discovering the problems of the Private Investigation Law mentioned in this study and collecting opinions from citizens, academics and related institutions. The introduction of the private investigation system requires the connection of the efforts and interests of citizens, academia and related institutions.

Based on the results of preceding researches that the uncertainty perceived by the private security guards about their roles exerts direct effects on the business performance of the security industry, it needs to preferentially examine the degree of authority that the private security guards have. The suitability of the psychological empowerment criteria for measuring this for private security guards, however, has not yet been established up to the present, so it can be said that the validity of the information has not yet been established. Accordingly, as the psychological empowerment criteria of private security guards, this research examined the suitability of items, reliability of items, the level of difficulty of items, and the item goodness of fit from the viewpoint of the appropriateness of category of responses, and it is summarized as follows. First, in the self-determinism factor of the psychological empowerment criteria, Item 11 was found to be an unsuitable item, so it is proper that Item 11 should be deleted when examining the psychological empowerment of private security guards from now on. Second, the item reliability of the psychological empowerment criteria was high, so the consistency of the results is shown even if the data are collected from the other private security guards. Third, they feel that it is hard to respond to Item 12 while they perceive that Item 1 is the easiest, and the level of items of the psychological empowerment criteria is evenly distributed. Fourth, it was established that the 5-point categories of the psychological empowerment criteria were suitable to the private security guards.

Current business environment asks the fundamental changes about business security. The essences of these changes are that the security management of today's global business is important task of managers and the security practitioner is professional who needs very specialized education and training with business thinking. Rapid process of globalization of global village tore down the business limit that was restricted on the geological areas' limitation. Rapid business environments' change that is driving depends on development of science and technology with globalization needs new paradigm to keep business continuity. With the process of globalization, Korea, which importance is gradually increasing in the national economy, has trade dependent economic system, which keeps power of national economy through trade, so Korean economic tendency is accelerating. To keep competitiveness in global market, new strategy that is different with existing domestic business management is necessary. That is, capacity of coping with outside risk in domestic business management is established in some degree, but business activities in foreign countries faces at numerous unexpected risks that differ from country to country such as difference with the custom, changes of corporate governance etc. To cope with these new risks effectively, new paradigm for business risk is necessary. Especially, flexibility of thinking like new paradigm is necessary to cope with new security risk effectively. To cope with security risk that occurs in the new business environment effectively and competes against international company in global market, company management and members' changes of cognition about security and innovative changes in security policy is necessary. In the basement of these changes, there is expansion of business security tasks, improvement of report line, enhancement of professionalism and status of security officers, variation of hands-on workers and increasing of investment to the security etc.

To develop the tourism industry, which is a 'no smoking environment-friendly green industry' and can contribute to creating jobs, it is the goal of top priority to resolve foreign tourists' discomfort and fear by allowing them to look around the country satisfactorily without fear and return to their home and inducing them to naturally promote tourism in South Korea to people around them. No matter how great tourist attractions a country has, there is not many foreign tourists who will go on a tour trembling with fear of crimes such as thefts, frauds, threats and blackmail. Therefore, it is necessary to prepare the conditions of tourism free from various illegal acts and inconveniences for domestic and foreign tourists, and for this, it is urgently necessary to make efforts to improve laws and institutions. Domestic tourists can report their complaints themselves through the Tourist Complaint Center of Korea Tourist Service, Inc. or Korea Consumer Agency, or to the police through the 112 Crime Report. In contrast, there are a lot of cases in which foreign tourists cannot receive compensation as it is not easy for them to report due to the differences in language, culture and the criminal justice system though they have suffered illegal acts or inconveniences. This, consequently, has an adverse effect that would disturb the tourism in South Korea as the tourists may spread its bad images to people around them after they return to their home countries with discomfort, so it is urgently necessary to establish a foreign tourist-centered tourist police system.

During the recent years, cyber attacks have been increasing both in the private sector and the government. Those include the DDOS cases in 2009, the Blue House cyber attack, bank hackings etc. Cyber threats are becoming increasingly serious. However, there is no basic law related to cyber security at present, and regulations related to cyber security are scattered in various domestic laws. This can lead to confusion in the application of the law and difficult to grasp the regulations related to cyber security. In order to overcome this situation, the bill on the prevention and countermeasures against cyber crisis was initiated in 2006, but it has been abrogated. Since then, it has been repeatedly proposed, but it has been abrogated repeatedly due to the overlapping of existing laws and concerns about infringement of personal information. The most recent initiative was the National Cyber Security Act, which was initiated by the government in January 2017. The act focuses on resolving the absence of a basic law related to cyber security, strengthening its responsiveness in the event of a cyber security crisis, and fostering security strength. Therefore, this study seeks to contribute to the establishment of National Cyber Security legislation as a basic law of cyber security by examining the necessity of National Cyber Security legislation through comparative legal analysis with existing domestic laws related to cyber security and suggesting policy implications.

Due to the development of technology and popularization of drone, the so-called "dirty drone" that exploits drones for crimes and terrorism has become a social problem, and it is time to seriously consider the "revenge of drones." Indeed, the cases of threats posed by drones are expanding not only to threats to ground facilities, but also to aviation safety threats, more recently to large-scale events, demonstrations and crimes targeting specific personnel, and terrorism. This research clearly defined the concept of anti-drone when it emerged as a new type of social safety threat as it was abused in crime and terrorism, while response to it was not enough yet. Through this process, it was intended to present an effective anti-drones system. We analyzed the major controversial elements of anti-drone, and defined them as "comprehensive response activities at the legal, institutional and technical levels performed by law enforcement agencies, related technology and industrial entities in a way that prevents, detects, and blocks acts that violate public well-being and order, such as crimes and terrorism caused by the drones." To effectively respond to dirty drones, the authority of law enforcement agencies and the enactment of relevant laws were proposed. In the future, a comprehensive and systematic follow-up study of the anti system should be conducted.

This study is trying to analyse the correlation between the crime behavior and the social alteration or development. Capitalism reposes on economic competition, and the impact of capitalism is according to crime behavior. Then the type of crime and the diversity of crime are transformed by the social environment and the social development. So this study is divide into 3 parts. The first is the correlation between industrialized and crime. It means that the industrialized is accompanied with the urbanized and arouse a material desire, these social phenomenon are a high correlation with increase of violent behavior and the crime. The second party is explain and analyse the correlation between the information and the crime. The information causes other type crime by contrast with the industrialized age and society. If the industrialized has caused the violent behavior and the crime, the information is too clever by half and break out the crime in the companionship of innumerable unspecifiness. So, the crime of the information age is a very wide scope and casualties, especially has a concealment of crime. And the third party describe in conclusion the social alteration and the extension of crime. Social alteration or social development is according to economic development. Competitive economic development include many complication and friction in a society, these factors are expressed in various crime. In the result the occurrence and the type of crime is a high correlation between the social alteration or development.

손목관증후군(CTS)이란 장기간에 걸쳐 여러가지 의학적, 생리학적, 직업적 요인들에 기인 하여 발생하는 누적외상병(Cumulative Trauma Disorders: CTD)의 대표적인 한 형태이다. 이 증 후근은 1960년에 국제노동기구(ILO)에 의해 직업병으로 인정되었으며 미국을 비롯한 구미각국에 서는 산업체에서 발생하는 작업손실시간및 산업재해보상으로 인한 경비손실에 중요한 요인의 하 나로 규정되어 이에 대한 예방책의 연구가 정부기관, 대학, 연구소, 그리고 산업체를 중심으로 활 발히 이루어지고 있으나, 우리나라에서는 아직 이에 대한 인식및 예방책에 관한 연구가 미흡한 실정이다. 본 논문에서는 직업적 요인을 중심으로 손목관증후군(CTS)의 발병가능성이 높은 직업 및 그 작업조건들을 고찰하고 이의 예방을 위한 연구방안을 다음과 같이 모색하였다. 첫째, 손목 관증후군에 관련된 문헌조사를 통하여 어떠한 직업들이 보다 높은 발병위험에 직면하고 있으며 어 떤 작업조건및 환경적 요인들이 손목관증후군(CTS)을 발병시킬수 있는가에 대하여 고찰하였다. 둘째, 미국등의 대학및 연구소에서 여러가지 작업조건들을 통제한 실험을 통하여 얻어진 이 증후군 의 발병율을 감소시키기 위한 여러가지 안전한 작업기준들을 검토하고 정부기관(NIOSH, OSHA)의 정책방향을 검토하였다. 세째, 미국의 연구소및 경영자문회사등에서 산업체를 대상으로 시행하고 종합적인 누적외상병(CTD)의 예방프로그램을 검토하였다. 마지막으로, 현재 우리나라의 손목관증 후군(CTS)을 중심으로한 누적외상병의 현실을 검토하고 앞으로의 예방을 위한 연구방향및 방법과 정책적 대응방안등에 대하여 연구검토하였다. 결론을 제시하고자 한다.기서 사용된 아이콘에 대해서만 타당한 것으로 이것을 모든 아이콘에 대해 일반화시키기는 어려우나 이후에 행해질 Icon-based User Interface 분야의 많은 연구들의 기초가 될 것이다. 더불어 아이콘과 관련된 많은 요인들(문화적 영향, 아이콘 색깔, 크기, 아이콘의 위치등이 인식에 미치는 영향)에 대해서도 연구가 행해져야 할 것이다. 확인하고 각각의 기능을 분명히 했다.가 수월하게 하였고 메모리를 동적으로 관리할 수 있게 하였다. 또한 기존의 smpl에 디버깅용 함수 및 설비(facility) 제어용 함수를 추가하여 시뮬레이션 프로그램 작성을 용이하게 하였다. 예를 들면 who_server(), who_queue(), pop_Q(), push_Q(), pop_server(), push_server(), we(), wf(), printfct() 같은 함수들이다. 또한 동시에 발생되는 사건들의 순서를 조종하기 위해, 동시에 발생할 수 있는 각각의 사건에 우선순위를 두어 이 우선 순위에 의하여 사건 리스트(event list)에서 자동적으로 사건들의 순서가 결정되도록 확장하였으며, 설비 제어방식에 있어서도 FIFO, LIFO, 우선 순위 방식등을 선택할 수 있도록 확장하였다. SIMPLE는 자료구조 및 프로그램이 공개되어 있으므로 프로그래머가 원하는 기능을 쉽게 추가할 수 있는 장점도 있다. 아울러 SMPLE에서 새로이 추가된 자료구조와 함수 및 설비제어 방식등을 활용하여 실제 중형급 시스템에 대한 시뮬레이션 구현과 시스템 분석의 예를 보인다._3$", chain segment, with the activation ener

This research addressed improvement directions and problems of regional science and technology(S&T) policies in Daegu and Gyungbuk regions in terms of 'Creative Economy' which was a new paradigm of Park Gunhye Government. Creative Economy stressed the construction of an ecosystem in regional research and development activities, and thus it was deeply associated with building a regional innovation system(RIS). There were several problems to strengthen RIS with regional S&T policies of the regions as follows: limits in meeting regional needs due to excessive attraction of central government's projects into regions; the high ratio of programs for future basic research potentials; the lack of programs assessing and coordinating the policies; and the lack of experiences and expenditure of research institutes and firm supporting organizations. Due to these problems, the role of the policies in building RIS did not seem to be effective. Therefore, the policies need to be improved through the following measures: the expansion of regional own policies focusing regional needs; the enhancement of policy coordination by shifting to systematic approach; the expansion of soft supporting programs for constructing innovation systems; and the enhancement of stability and ability of research institutes and firm supporting organizations.
