본 연구는 500병상 규모의 병원에서 PACS 도입 시 준비 작업 및 제안서에 포함 되어야 할 항목과 의료장비 도입 전 검토조서의 제시로 장비 도입 전 수익성 및 운용 부서에서 계획서에 제시 된 예상수익을 근거로 하여 장비의 이용도와 수익성을 조사하여 고가의료장비의 구입 원가, 이용도 등을 분석하였다. 연구대상 병원에서 PACS 도입 시 수가로 인하여 수익이 발생되는 것으로 나타났고, 의료장비 구입 방법은 임차 방식으로 기간은 3년에서 5년으로 나타났으며, 수익은 2년 정도이면 투자비용을 상회하여 수익이 발생 될 것으로 예상되었다. 병원의 PACS를 도입 운영에 있어서 의료장비 구매 금액은 영상의학과의 운영에서 발생되는 수익을 근거로 할 때 투자비용은 약 1.9년 정도이면 투자금액을 회수 할 수 있을 것으로 예상되었으며, 영상의학과의 재촬영 검사의 감소와 필름 및 현상 정착액을 구입하지 않아 운영비를 절감할 수 있는 것으로 나타났다. 또한, 실질적인 수익 증가 외에도 병원 마케팅 차원에서 병원의 위상 향상, 직원들의 업무절감 등에 의한 업무 환경개선 또는 업무 스트레스 감소 등 병원 직원의 업무 만족도 증가로 인한 병원의 서비스 향상에도 기여하는 것으로 나타났다. 이와 같은 결과 병원규모에서 PACS 도입 시 의료장비의 예상 수익을 작성하고 진료업무의 기여도 및 구매 후에도 수익 등을 비교 분석하여 의료장비 도입 전 제안서 작성과 도입 후 효율적인 장비 운영 계획을 수립해야 할 것으로 사료되었다.

본 연구는 보험감독규정과 보험회계준칙의 분리계정(구분계리 포함) 관련 규정을 개선하기 위한 대안을 제시하기 위해 수행되었다. 구분계리, 포괄적으로는 분리계정은 회계의 투명성을 증가시키고 보험회사의 주주와 보험계약자 사이의 이익 배분의 공정성을 높이는데 기여할 수 있다. 구분계리의 유용성을 높이기 위해서는 국제회계기준의 변화된 내용, 보험상품별 성과 구분, 보험상품별 경제적 실질이 반영될 수 있어야 한다. 분리계정이 성공적으로 정착된다면 보험계약자에 대한 공정한 이익배분 뿐만 아니라 생명보험회사 상장시의 보험계약자 이익 보호와 관련된 논쟁의 해결에도 기여할 것이다.

The purpose of the this paper is to make decision of the maintenance priority of power distribution system using Time-Varying Failure Rate(TVFR) with interruption cost. This paper emphasizes the practical use of the reliability indices and interruption cost. To make a decision of maintenance priority on power distribution system equipment, the quantification of the reliability level should be represented as a cost. In this paper, the TVFR of power distribution system equipment applied in this paper utilizes analytic method to use the historical data of KEPCO. From this result, the sensitivity analysis on TVFR of equipment was done for the priority, which represents that high priority of the equipment has more effect on system reliability, such as SAIDI or SAIFI, than other equipment. By this priority, the investment plan is established. In this result, customer interruption cost(CIC) could be extracted, and CIC is used as weighting factor to consider a importance of customer. After that, the result calculated the proposal method in this paper is compared with other priority method, such as lifetime, failure rate or only sensitivity.

Since the passing of the Personal Information Act in March 2011 and its initial introduction in September, over the one year to date diverse security devices and solutions have been flowing into the market to enable observance of the relevant laws. Beginning with security consulting, corporations and institutions have focused on technology-based business in order to enable observance of those laws competitively in accordance with 6-step key procedures including proposal, materialization, introduction, construction, implementation, and execution. However there has not been any investment in human resources in the field of education such as technology education and policy education relative to the most important human resources field nor investment in professionals in the organization for the protection of personal information or in human resources for operating and managing IT infrastructure for actual entire personal information such as special sub-organizations. In this situation, as one process of attracting change from the nature of the technology-based security market toward a professional human resource-based security infrastructure market, it is necessary to conduct research into standardization modeling concerning special organizational composition and a management system for the protection of personal information.

Comparative analysis to secure safety of Blockchain Many investors have invested in virtual currency such as bit coins as a new investment due to increased popularity of virtual currency around the world. Also, virtual currency such as bit coin has a security technology and it has been relatively proved. popularity of virtual currency is rising as a new investment alternative because of this reason. This paper focused on the block chain's transparency and security of distributed ledger technology, which is relatively safe without third party's intervention. Many governments and companies around the world are developing and working on block chain technological development to introduce due to these reasons However, there are some suggestion that block chain has minor risks to its security. In this paper, it will examine security vulnerabilities from importance of security of Blockchain which relates to transactions of Bitcoin which stored by governments and companies around the world. This paper will propose measure which will improve safety and efficiency of Blockchain technology such as the existing Blockchain method, Blockchain proposal, traceability and awareness about hacking.

The present research has been conducted on the arranged form, the number and kinds, the area, the location of the rooms and the variation on exterior designs, based on a layout and a ground plan of each step, which are general plan, VE proposal and the final negotiation, for 11 elementary and middle and high schools that are designed in the way of BTL project. In consequence, it has been found out that there are some changes in the number and position of the rooms. However, the changes are not exceeding the overall arrangement form. This could not have led to the original aim, which is to induce creativity by PFI. It can be supposed that it is because the BTL system is stick to the old process, the method of financial investment and it is true to say that there needs to be solution for that.

This research aims to propose a model to estimate the appropriate SE Cost rate to the total project cost when systems engineering applied to light rail transit project. In this research an investment cost estimation model is proposed with reference to COSYSMO (Constructive System Engineering Cost Model). This model includes four input factors such as requirement numbers, interface numbers, algorithm numbers, and scenario numbers. When 2600 requirement numbers are considered on a proposal document with 350 pages in a light rail transit specification of 500 billion~trillion won scale, COSYSMO demo version estimates 42.5 billion won of SE cost (about 5% of total project cost or about 10% of E&M cost).

India faces a formidable challenge in ensuring security of access to modern energy carriers to majority of its population. The fossil-fuel dominated centralized energy system has proved to be ineffective in creating sustainable access to energy, which suggests need for a radical and innovative approach. We present such an approach. First, the need for innovations given the implications of lack of energy access on sustainable development is assessed. Next, possible innovations with respect to technologies, policies, institutions, markets, financial instruments and business models are discussed. Finally, an economic and financial feasibility of implementing such innovations are analyzed. The results indicate that such a proposal needs an investment of US$ 26.2 billion over a period of 20 years for a GHG mitigation potential of 213Tg $CO_{2e}$. The proposition is profitable for the enterprises with IRRs in the range of 39%-66%. The households will get lifeline access to electricity and gas for cooking at an affordable monthly cost of about US$ 5.7.

Information Technology (IT) makes a great contribution towards improvement of productivity in construction industry. Because most of researches of construction industry's IT are focused on the whole field of the industry or development of information system, however, these have no regard for conditions in fields. Thus, this study proposes the requirements in order to improve the productivity and efficiency of field execution of construction industry. To achieve this aim, the surveys are conducted of the problems and conditions of IT application on site workers and managers. As a result, the followings are suggested: (1) user training should be exercised continuously, (2) infrastructure of IT constructed, (3) total management system of field execution developed, and (4) the development of IT system focused on fields. Therefore, this study provides meaningful proposal that can be set up basic direction toward IT investment and IT system development.
