정보통신환경발달과 함께 지식사회에서 암호의 역할이 증대됨에 따라 OECD의 암호정책가이드라인 공표를 시점으로 각 국은 자국의 신정에 맞는 새로운 암호정책을 세우고 이에 따른 법$\cdot$제도를 정비하기 위해 본격적인 노력을 기울여오고 있다. 하지만 암호는 개인의 프라이버시를 보호할 수 있는 가장 유용한 수단인데 반해 암호의 범죄이용 등으로 인한 국가의 안녕과 법질서 혼란을 초래할 수 있다는 역기능도 상존하고 있다. 각 국의 정부는 이러한 우려 때문에 암호이용을 제한적으로 규제하려는 정책을 시도하여 왔으나 시민단체의 반대에 부딪쳐 암호의 자율이용 원칙과 국가 합법적 통제제고의 균형을 맞출 수 있는 암호정책을 세우는데 고심하고 있다. 본 교에서는 미국, 영국, 프랑스, 중국 등 주요 국가론 중심으로 암호이용을 활성화하고 암호의 역기능을 방지하기 위해 세운 암호정책 및 암호이용 관련 법제도 현황을 살펴보았다.

Due to recent growth in IT industry along with the expansion of smartphone, we came to connect to the Internet wherever and whenever we are. However, this causes negative side effects, though. One of them is a rapid increase of the financial crimes such as the Phishing and the SMishing. There have been many on-going researches about crimes such as Phishing and SMishing to protect users. However, the study about sharing knowledge on SNS to prevent such a crime can be hardly found. Based on social identity theory, we conduct the research about factors on SNS users' intention to share the information security knowledge on SNS. As a result, we found that knowledge provision self-efficacy has a significant impact on self-expression. In addition, it also found out self-expression, awareness about information security and the sense of belonging have a significant impact respectively on the intention to share the information security knowledge on SNS. On the other hand, the altruism didn't have a significant impact to the intention to share information security knowledge on SNS. With this research as a starting point, it seems necessary to expand its range to all types of online community in the future for the generalization of the hypotheses.

At present, CPTED projects are showing an effect such as reducing the anxiety of residents from crimes and improving the criminal environment about crimes through crime prevention. However, most of the CPTED programs have been implemented mainly to improve the physical environment without verifying systematically and empirically on the relationship between the program and improving the quality of life of residents and satisfaction level of residents etc. Accordingly, the objective of this study is to grope for a plan to apply CPTED to urban regeneration for improvement in the safety and life quality of residents using AHP and Visualizing The Mental Map. For this, We selected four case areas in Busan and then analyzed the dead zones of CPTED programs by visualizing the mental maps and heat maps of residents for case districts. As a result of evaluating the priority of CPTED program, installation of CCTVs and streetlights for prevention of crimes was found to be the most important elements. Result of analyzing mental map, the existing crime prevention facilities and CPTED programs were found to have resolved most of physical disorder. However, it showed that, for psychological factors which the residents feel such as social disorder, a number of dead zones exist.

UNCLOS recognizes the right of innocent passage in the ocean but grants jurisdiction and governance to the state of the flag the vessel flies. However, by granting the right to determine vessel's nationality to each country in UNCLOS and by practically consenting inconsistency with the ownership and the state of flag has made the keeping of maritime order quite difficult. Especially, acknowledging the exclusive rights of the flag state on criminal jurisdiction hinders the owner state from exercising its rights and exposes the problem of not taking into account the opinion of the affected state party. This study addresses these issues and examines international regulations on vessels and flag states, mainly UNCLOS, and provides case studies on how criminal jurisdiction is determined when accidents occur at sea. Furthermore, it takes a deeper look into the mutual assistance system in criminal matters and proposes some alternatives on how to overcome these issues.

As the technologies of the 4th industrial revolution develops, spatial information is becoming digitized. Now, even with a smartphone, we can easily identify the location of national & military critical facilities located in the mega cities. As a result, mega cities' national & military critical facilities were exposed to not only traditional threats, but also non-traditional threats such as terrorism, cyber hacking, and criminal activities. This study suggests a way to protect national & military critical facilities of mega cities from such threats. Considering limitation of time & resources, protecting perfectly all national & military critical facilities is impossible, so we should focus on their critical nodes. Specifically, We suggest ways to protect the critical nodes by converging some measures such as design & arrangement in harmony with the surrounding environment, underground construction & covering, and visual deception. Transparency of digital spatial information will further increase with the advent of urban air mobility and autonomous vehicles in the future. Therefore, in order to prepare for future threats, we should take measures to minimize the exposure of critical nodes.

Since mechanical security systems are mostly composed of electronic, information and communication devices, they have effects in the aspects of overall social environment and crime-oriented environment. Also, the importance is increasing for wireless recognition of RFID and tracing function, which will be usefully utilized in controlling the incomings and outgoings of people/vehicles or allowance, surveillance and control. This is resulting from the increase in the care for the elderly according to the overall social environment, namely, the aging society, and the number of women entering, as well as the increase in the number of heinous crimes. The purpose of this study is to examine the theoretical considerations on ubiquitous sensor network and present a direction for securities companies for their development by focusing on the technological and application areas. To present strategies of response to a new environment for security companies, First, a diversification strategy is needed for security companies. The survival of only high level of security companies in accordance with the principle of liberal market competition will bring forth qualitative growth and competitiveness of security market. Second, active promotion by security companies is needed. It is no exaggeration to say that we are living in the modern society in the sea of advertisements and propaganda. The promotional activities that emphasize the areas of activity or importance of security need to be actively carried out using the mass media to change the aware of people regarding security companies, and they need to come up with a plan to simultaneously carry out the promotional activities that emphasize the public aspect of security by well utilizing the recent trend that the activities of security agents are being used as a topic in movies or TV dramas. Third, technically complementary establishment of ubiquitous sensor network and electronic tag is needed. Since they are used in mobile electronic tag services such as U-Home and U-Health Care, they are used throughout our lives by forming electronic tag environment within safe ubiquitous sensor network based on the existing privacy guideline for the support of mobile electronic tag terminal commercialization, reduction in communication and information usage costs, continuous technical development and strengthening of privacy protection, and the system of cooperation of academic-industrial-research needs to be established among the academic world and private research institutes for these parts.

A new urban paradigm that moves from a vehicle-centric to pedestrian-centric culture should be considered to improve the quality of the pedestrian environments for women, children, senior citizens, and disabled persons as well as to promote community unification by providing general movement rights to everyone. This study was implemented to provide decent alternatives to improve street spaces. The street spaces around the Commercial and Residential Area No.1 located in the Administrative-Centered City, Sejong Special Autonomic City, were selected to analyze and define the status of the walkways and the street spaces. Satellite imagery and numerical maps were used to collect geographic data. Practical and actual surveys for the selected sites were performed to analyze the street status and the pedestrian status. Based on the all collected data, analysis results, and literature reviews, the questionnaire was made, and 315 inquiries qualified for analysis. The physical status of all four study sites was the highest level, Grade A, and green open spaces were relatively sufficient. As a result, the factors obtained from the factor analysis have an impact on the satisfaction of the pedestrian streets in the commercial area. The factors are as followed Design > Convenience > Roadside trees and rest areas > Safety > Safety protective facilities > Transportation and information facilities > Continuity > Basic state of road surfaces > Comfortability, and in the residential area: Transportation and information facilities > Basic state of road surfaces > Comfort > Convenience > Continuity > Design > Illumination and crime prevention facilities > Safety > Roadside trees and rest areas.

This study analyzed the consciousness and attitudes of local residents to the development plan of Sobaeksan Jarackgil by applying the social exchange theory to provide basic data for the establishment of the Mountainous Ecology Trail Development Plan, collecting opinions of local residents. For this, we conducted a self-administered questionnaire survey and personal interview targeting 150 residents of seven villages. Summarizing the results, first, because of analyzing the consciousness of the residents, most of the local residents turned out to be aware of the Sobaeksan Jarackgil development plan and agreed on it. Second, as a result of analyzing the consciousness of residents, for attitudes according to gender, females expected more than males of exchanging with visitors and excavation of cultural assets. Furthermore for attitudes according to age, groups aged under 60 turned out to be concerned about the increase of environmental pollutions, rise in crimes, destruction of cultures, and the induction of conflicts among residents. For attitudes according to occupations, farm workers were worried about the destruction of ecology, and for local characteristics and damages to the landscape, all of the local residents turned out to be concerned. It was shown that groups that agreed on the development plan expected positively on most of the items of economic, environmental, and sociocultural aspects, while those that disagreed on the plan were anxious for negative effects such as landscape damages and the increase of environmental pollutions from the environmental point of view, and the induction of conflicts among residents from the point of sociocultural perspective.
