본 연구에서는 EDI감사 의사결정지원시스템을 개발하였다. 이를 위해서 기존의 EDP감사 의사결정지원시스템 및 감사전문가시스템분야의 연구를 고찰했다. EDI감사를 위한 의사결정지원시스템은 통계, 위험, 회사의 개요, 테스트 항목등의 데이타를 저장한 데이타베이스 시스템이다. 시스템 개발을 위해서 E/R(Entity Relation)이나 DFD(Data Flow Diagram)분석을 통해서 논리적인 설계를 하였다. 시스템 개발은 개인용 데이타베이스팩키지인 FoxPro를 사용하였다. 이 시스템을 통해서 감사인이 필요한 테스트 결과를 조회하거난 저장할 수 있고 통제, 위험, 회사등의 상호조회를 통한 필요한 통제나 위험정도를 쉽게 조회해 볼수 있다. 회사마다 필요한 통제, 위험, 테스트 항목등의 체크리스트가 달라지는 경우에 이 시스템을 통해서 입력 저장하여 각각의 회사에 대해 다른 체크리스트를 저장하여 놓을수 있다. 본 시스템은 EDI감사뿐만 아니라 일반 EDP감사분야에도 적용가능할 것이다. 종이를 사용한 감사증적이 없음으로 인해 수작업에 의한 EDI감사는 어려움이 있고 EDP감사시스템분야의 국내 연구가 전무한 실정에서 EDI감사를 지원하는 시스템의 연구는 의의를 갖는다고 생각된다. 본 시스템을 통해서 EDI의 보안 및 감사업무의 효율성이 높아지고 EDI에 대한 위험에 효율적으로 대처할수 있게 될 것이다. 그리고 이러한 보안 및 감사기법과 통제모형을 지식베이스로 구축해서 실제의 위험노출상황에서 가능한 보안을 위한 통제방안이 여러가지가 있는 경우에 비용/편익 분석, 효율성, 회사방침 및 법률적인 문제등을 고려해서 최적의 보안통제 및 감사기법을 선택하는 것을 지원할 수 있을 것이다.고리듬을 개발 함으로써 내부점 선형계획법의 수행속도의 개선에 도움이 될 것이다.성요소들을 제시하였다.용자 만족도가 보다 높은 것으 로 나타났다. 할 수 있는 효율적인 distributed system를 개발하는 것을 제시하였다. 본 논문은 데이타베이스론의 입장에서 아직 정립되어 있지 않은 분산 환경하에서의 관계형 데이타베이스의 데이타관리의 분류체계를 나름대로 정립하였다는데 그 의의가 있다. 또한 이것의 응용은 현재 분산데이타베이스 구축에 있어 나타나는 기술적인 문제점들을 어느정도 보완할 수 있다는 점에서 그 중요성이 있다.ence of a small(IxEpc),hot(Tex> SOK) core which contains two tempegatlue peaks at -15" east and north of MDS.

In recent years, industrial convergence centered on ICBM (internet of things (IoT), cloud, big data, mobile) has been experiencing rapid development in various fields such as agriculture and the financial industry. In order to prepare for cyber threats, one of the biggest problems facing the convergence industry in the future, the development of the industry must proceed in tandem with a framework of information security. In this study, we analyze the details of the current industrial development policy and related information protection policies using cross impact analysis and present policy priorities through the expert questionnaire. The aim of the study was to clarify the priorities and interrelationships within information security policy as a first step in suggesting effective policy direction. As a result, all six information security policy tasks derived from this study belong to key drivers. Considering the importance of policies, policies such as improving the constitution of the security industry and strengthening of support, training of information protection talent, and investing in the information security industry need to be implemented relatively first.

The security law and security industry of Japan have a great impact on Korea. In a modern sense, there are little large disparities between the two nations in the history and development of private security. However, the way they look at private security is not the same in large part. In Japan, private security companies are highly regarded by Japanese people as organizations that guarantee their safety, owing to the efforts of private security companies themselves, the National Security Association and civic groups. Private security has especially been approved and supported since it was decided in the anticrime cabinet council in December, 2003, in line with the action plan for the realization of anticrime society to boost private security as an industry to ensure people's safety in daily routine life by curbing crimes that might pose a threat to peaceful life. Afterwards, there has been a dynamic collaboration between the Japanese police and private security in terms of education, crime prevention, disaster prevention/restoration and everyday life safety. As for Korea, the necessity of cooperation between private security and the police is increasingly stressed, and it's required to strengthen their partnership to ensure successful crime prevention in consideration of Japanese partnership cases. In Japan, the police, civic groups, the security association and security companies make every effort to satisfy Japanese people's safety needs in diverse ways and take disaster-prevention measures as well.

Recently, many domestic and foreign corporates are concentrating in investment to wearable devices and users are provided with various service based on wearable devices 26% more than compared to last year. It is widely used in previous healthcare, smart work, smart home environment, and it is now introduced to get connection to fused service environment. However, as products of G company are commercialized, the security issue of personal information is causing dispute in society, and the danger of data management and security regarding telecommunication is increasing. Also, because the password system used in previous wireless environment is still in use, there are possible vulnerability considering the new and mutant security threat. This thesis conducted study about protocols that can exercise safe telecommunication in the basis of wearable devices. In the registration and certification process, the signature value is created based on the code value. The telecommunication method is designed to conduct safe telecommunication based on the signature value. As for the attack method occurring in the wearable device environment, the safety was analyzed and conducted performance evaluation of previous password system and proposal system, and verified about 14% of efficiency.

As the security system using facial recognition, the recognition performance depends on the environments (e. g. face expression, hair style, age and make-up etc.) For the revision of easily changeable environment, it's generally used to set up the threshold, replace the face image which covers the threshold into images already registered, and update the face images additionally. However, this usage has the weakness of inaccuracy matching results or can easily active by analogous face images. So, we propose the genetic algorithm which absorbs greatly the facial similarity degree and the recognition target variety, and has excellence studying capacity to avoid registering inaccuracy. We experimented variable and similar face images (each 30 face images per one, total 300 images) and performed inherent face images based on ingredient analysis as face recognition technique. The proposed method resulted in not only the recognition improvement of a dominant gene but also decreasing the reaction rate to a recessive gene.

Our country is a nation accomplished the economic growth and democracy at the same time on the bases of human capitals. However, the laborers as human capitals are aging as well due to the population aging. These aging phenomena are impacting on our country's economy, society, and through the culture. It seems to increase the proportion of the elderly in the labor market of private security caused by continuously increasing the number of elderly employees in long-term trend and their preferences for the security services. These changes of labor market trend may result various problems including relevant laws and systems, the changes of laborers' ability, increase of crimes and so on. To prevent such potential problems, firstly the limits of maximum working hours of elderly private guards have to be set up, and the rest times for them must be secured. Furthermore, the declines of elderly laborers' abilities have to be reduced through the systematic educations relevant to their jobs to cover the rapidly declining elderly laborers' physical abilities. Lastly, the increase of crimes should be reduced through the education contents to be able to arouse their attentions by extending the time of job training and informing of criminal cases.

The trend of business work that is related to supply chain changed into e-business using the electronic document However, the small and medium enterprise organizations still use huge volume of paper document, especially in private sector. Recently, the need for eco-friendly and low cost logistics becomes increasing. For this, it has expanded to exchange or to use e-document rather than the paper or manual processing in supply chain business. Therefore, this paper proposed the electronic access system for supply chain by business process modeling. If it is using the proposed system, it can be saving the exchanged or the scanned document to system, and user can utilize that document on just accessing system whenever they need the document. We believe it might reduce the burden of each organization because they don't need to save large volume data to their system or place. Furthermore, the benefits will effect across the national as well as global.

The U.S. security regulation is under the influence of each state's law; however, they are mostly similar. Among many states which has the longest history of security regulation in the U.S., state of New York has been shown security regulation for a long time. The state of New York has been emphasized the importance of security significantly because it is economically, culturally, and internationally important place at the same time. New York's state law of security business includes: 1. private investigators and bail enforcement agents and watch, guard or patrol agencies license law. 2. Security guard act of 1992~,3. Title 19 New York State's code of rules and regulation (NYCRR). The law of New York City's private security could inspire Korean private security law in many ways. First, administration of professional law and variety of licensure could be an inspiration to the Korean security services. Second, there are intimate partnership between police and private security in the U.S. New York police's private security partnership has been started since 1986 by Area Police/Private Security Liaison (APPL program) and there are about 1,300 of security companies participating. This program provides not only the simple partnership but also giving essential information for promoting public safety.
