The Electronic Shelf Label (ESL) is an alternative to the paper price label attached to merchandise shelves and is attracting attention as a retail IoT infrastructure that will lead the innovation of offline retail outlets. In general, when introducing a substitute product, the company tends to consider the financial factors such as the efficiency of the investment cost compared to the existing product or the reduction of the operating cost. However, considering only financial factors in the decision-making process, it may not properly reflect the various values associated with corporate strategy and the requirements of stakeholders. In this study, 8 evaluation items (Investment Cost, Operating Cost, Quality Level, Customer Management, Job Efficiency, Maintenance, Functional Expandability, and Store Image) based on BSC's 4 perspectives (Financial, Customer, Internal Business Process, Learning & Growth), and using AHP (Analytic Hierarchy Process) to measure the priorities of evaluation items for domestic small supermarket employees. As a result of the research, priority was given in order of Customer, Learning & Growth, Internal Business Process, and Financial aspects among the evaluation items for adopting the price label, and the electronic price label was supported with higher importance than the paper price label. In contrast to the priorities of the financial aspects of most prior studies, the items of Learning & growth and customer perspectives have relatively high priorities. In particular, respondents classified by job group, The priorities of the 8 evaluation items were different among the groups. These results are expected to provide implications for both companies (retail outlets) and ESL providers (manufacturers and service providers) who are considering the introduction of ESL.

There is various points that should be improved in Fairness such as our contract practice to propose construction projects, project managing and the stakeholders' way of thinking and culture. We consider that the revision of construction related provisions and systems is required but even more, an overall change in business management through the implementation of Integrated Construction Information Management System that will enable the owner, which drives the project, and contractor sharing construction information is required. To mange construction related information in an integrated manner, designing information should be smoothly transferred to purchasing information, and changes are required in order to move ahead to process-oriented work system. Finally information created from various construction organizations should be delivered in an aligned and standardized manner as well. The domestic Nuclear Power Plant Construction has been accepting various technology transfers from U.S, France, Canada and UK, which enabled us to self-support technology and recently even proceeded to the phase exporting our technology to others. However, continuous effort is required to improve internal business efficiency and to respond to external environmental change such aselectricity market deregulation. Recently, in accordance with the result in number of CEO's intention to make progress in IT and improve business efficiency, the number of enterprises introducing Enterprise Resource Planning is increasing. ERP is an innovative tool which changes the way of performing work from organization and department orientation to process-orientation in order to optimize the resources, such as human and material resources, through out the Enterprise by performing BPR which will maximize overall business efficiency of the enterprise, such includes not only construction management, but also business management. KHNP continued to performing large scaled construction projects such as nuclear power plant construction for past 30 years and took the initiatives of large scale project management and Quality management ability in domestic industry by having independent capability of over all construction planning, purchasing and, construction and start up management etc. To maintain our leading position of improving construction management technology based on our accumulated project management experience and technology, KHNP included construction into our ERP project in purpose of innovating construction business. We would like to discuss the characteristics of nuclear construction business, project management system, information system infrastructure and information sharing system among construction related entities, and implementation practices for information system, and consider how to resolve our practice that should be improved in this thesis.

Financial industries have operated internal and external network with an unified system for continual business process of customers and other organizations in the past. The financial supervising authority requires more technical and managerial protecting policy to financial industries related to the exposure as danger of external attacks or information leakage. Financial industries performed network separation into internal business and external internet networks for protecting IT assets from malware infection accessing internet or hacking attacks and prohibiting leakage of customers' personal and financial information following financial supervising authority and redefine security policy to fit on network separated-condition. In this study, effectiveness for network separation policy was examined on malware inflow and verified that malware inflow in all routes can be blocked by the policy with analyzing operration data of a financial company, estimating network separation. Result of this study proves that malware infection route by portable storages was not completely blocked even on adapting network-separated condition. As a solution for this, efficient security policy would be suggested in this paper as controlling portable storages for maximizing effectiveness of network separation.

그 동안 지속적인 경제성장을 바탕으로 한국의 생명보험산업은 양적으로 성장하였다. 그러나 내면을 살펴보면 외형을 떠받칠 만큼 내실있게 성장했는지에 대해서는 많으 의구심을 갖게 한다. 현실적으로 경제성장을 바탕으로 한 외형성장은 한계를 맞을 수 밖에 없으며, 이제는 질적인 내실을 기하기 위해 그 동안 소홀히 했던 보함산업의 전반의 체질개선이 필요하다. IMF이후 경영이 부실한 보험사들이 퇴출되면서 전면적인 개편이 이루어졌고, 또한 보험사 내부에서도 전반적인 개혁의 필요성을 인식하여 여러 방면으로 방안을 구체화하고 있다. 본 논문은 이러한 상황하에서 생명보험산업의 기존 문제점 개선방안의 일환으로, 보험산업의 가장 핵심분야라 할 수 있는 언더라이팅 분야의 국내현황을 살펴보면서 보험선진국의 제도 및 운영현황과 비교 분석하여 부문별 문제점을 도출하고, 그에 따른 개선방안을 제안하게 되었으며, 본 논문에서 제시된 개선방안을 요약해 보면 다음과 같다. 첫째, 언더라이팅을 신속 정확하게 수행하고 도덕적 위험을 배제하기 위하여 개선된 정보교환시스템 제도를 구축해야 하며, 사정자료의 수집업무를 전문기관에게 아웃소싱함으로써 비용절감을 기하여야 한다. 이와 아울러 모집인의 전문성을 제고시켜 보험계약 청약서와 모집인 보고서가 정확하게 작성되도록 하고 언더라이팅 실적과 연계한 인센티브제도에 의하여 모집수당이 지급되도록 하여 언더라이팅이 효과적으로 수행되도록해야 할 것이다. 둘째, 언더라이팅기법의 선진화를 기함으로써 위험에 상응하는 보험료를 부가하여 위험에 노출되어 있는 가망고객의 보험가입율을 높이고, 보험사고 발생시 실질적인 보험혜택을 누리도록 하여야 한다. 이를 위한 실천방안으로 의적 직업적 재정적 언더라이팅 선진기법을 도입하여 각 부문의 역량을 강화해야 할 것이다. 특히 제도적으로 개인신용정보의 언더라이팅 활용이 제한되어 있는 현실에서 이를 법제도 내로 흡수하면서 개인의 사생활 유지라는 목적을 동시에 달성되도록 하는 재정적 언더라이팅 기법의 강화가 특히 중요하리라 생각된다. 아울러 언더라이팅 업무를 효과적 효율적 수행을 통해 일관성 있는 의사결정이 이루어질 수 있도록 지원하는 언더라이팅 시스템구축을 통해 정형화된 인수과정은 결정시스템화하고, 복잡한 위험의 경우 자문 시스템으로 운영하여 간단한 언더라이팅 업무는 구축된 시스템을 통해 즉각 해결함으로써 시간을 절약할 수 있고, 언더라이팅 인력은 보다 전문적인 부문에 집중하도록 해야 할 것이다. 마지막으로, 비표준위험시장의 활성화를 위해서는 현재의 제약조건인 생명보험 상품개발을 세트형에서 조립형으로 전환하고, 재보험으로 위험을 분산하여 비표준위험의 인수를 증대하여야 할 것이다. 이와 더불어 언더라이팅 과정에서 얻어진 피보험자의 사정자료를 활용하여 고객에게 필요한 의료정보 등을 제공함으로써, 피보험자와 유대관계를 돈독히 하여 기존계약이 계속 유지되도록 하며, 추가계약이 이루어지도록 해야 할 것이다. 이상과 같은 비표준위험의 언더라이팅 개선방안이 보다 효과적으로 수행되고 발전하기 위해서는 통계축적 및 관리, 전문 언더라이터 양성, 전산을 이용한 언더라이팅 확대 등이 이루어져야 하므로 향후 이에 대한 집중적인 연구가 있어야 할 것이다.

Wireless networks make the users' work more convenient and efficient, but such networks can impair the availability of network resources and can cause leakage of important corporate information when there are security threats. In particular, damage has increased because of security attacks that take advantage of the vulnerabilities created by a wireless AP (Access Point). Public organizations and companies have gradually selected the WIPS (Wireless Intrusion Prevention System) to block wireless security threats and protect the internal network. However, it is very costly for other organizations and companies to introduce the WIPS solution. This paper proposes implementing a WIPS Sensor by using Raspberry Pi to reduce these costs and to block the various wireless LAN security threats. This implementation would protect corporate information and provide consistent services at a relatively reasonable price.

The fire accident is a representative type of disaster that can largely impact on business. Therefore, precautionary measures and rapid initial response is very important when a disaster occurs. The storage of porous combustibles is inevitable in coal yard, plywood processing industry, and others that are currently operating. Initial fire fighting of fire and identifying the ignition point in such a porous combustible storage space are so difficult that if the initial response is failed, being led to deep-seated fire, surface fire is likely to result in secondary damage. In addition, deep-seated fire can cause personal injuries and property damage due to a large amount of toxic gases and reignition. Therefore damage reduction measures is required around the storage space to handle a porous flammable. Improving the penetration performance of the concentration of the surfactant is carried out as underlying study, which is about an deep-seated fire extinguishing efficiency augmentation when using wetting agents. The porous materials used in the experiments is radiata pine wood flour, which occupies more than 75% of the domestic wood market. Fire fighting water is selected as Butyl Di Glycol (BDG), which is being used for infiltration extinguishing agent, and the experiment was carried out by producing a standard solution. The experiment was carried out on the basis of the Deep-Seated Fire Test of NFPA 18. The amount of watering, porous material to the internal amount of penetration, and runoff measurement out of the porous material was conducted. According to experimental results, as the surface tension is reduced, the surfactant concentration macroscopic penetration rate decreases, but infiltration to a porous material is shown to have growth characteristics.

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.

The purpose of this article was to propose improvement of countermeasure for missing person cases. While current related other studies examined practice of the countermeasure from inner viewpoint of police authorities itself, this study focused on and analyzed concern or criticism expressed through mass media, outside of the authorities. For this purpose, we analyzed newspaper articles dealing with missing person issued during past 5 years with qualitative data analysis software. The analysis revealed that civil community demands immediacy of coping with missing, phased expertise, systemicity of the countermeasure, improvement of relating policy, and active liaison with community. According to the needs, we proposed advancing risk assessment procedure, enlarging dedicated team for missing case, improving profiling-input system, adding duty for family of missing person, and enhancing of function of control tower.
