Recently reliability Improvement and certification are considered as important issues by world-wide leading and highly qualified companies in advanced countries. In Korea, from a few years ago, the policy for reliability certification newly has been driven to improve product competitiveness in part and material industry. As yet the reliability certification is local and domestic, it is necessary to develop local certification system to global certification system. Reliability certification system is composed of accreditation body, testing laboratory and reliability assurance. In this paper, we review the reliability certification system and its application in Korea and the current research trends in advanced countries. Finally we propose some suggestions for the eliability certification system to be an international standard.

The paper aims to facilitate a discussion around how big data technologies and data from citizens can be used to help public administration, society, and policy-making to improve community's lives. This paper discusses opportunities and challenges of big data strategies for government, society, and policy-making. It employs the presentation of numerous practical examples from different parts of the world, where public-service delivery has seen transformation and where initiatives have been taken forward that have revolutionized the way governments at different levels engage with the citizens, and how governments and civil society have adopted evidence-driven policy-making through innovative and efficient use of big data analytics. The examples include the governments of the United States, China, the United Kingdom, and India, and different levels of government agencies in the public services of fraud detection, financial market analysis, healthcare and public health, government oversight, education, crime fighting, environmental protection, energy exploration, agriculture, weather forecasting, and ecosystem management. The examples also include smart cities in Korea, China, Japan, India, Canada, Singapore, the United Kingdom, and the European Union. This paper makes some recommendations about how big data strategies transform the government and public services to become more citizen-centric, responsive, accountable and transparent.

Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

최근 공익 마케팅은 브랜드 포지셔닝의 주요 전략으로 활용되고 있다. 본 연구에서는 공익 마케팅 유형에 따른 소비자 반응의 상이함과 이에 영향을 주는 요인들에 주목하였다. 실제 브랜드의 공익 마케팅 활동과 이에 참여하는 소비자를 대상으로 조사를 시행한 결과, 자발적으로 참여하는 형태와 기업이 주도하는 형태는 공익 마케팅 대상 브랜드에 대한 진정성 지각에 상이한 영향을 주었으며, 이는 브랜드 인지도에 의해 조절되었다. 구체적으로, 자발 참여형에서 기업 주도형 보다 구매의도와 브랜드 진정성이 높았다. 유형별로 살펴본 결과, 기업 주도형은 브랜드 인지도가 낮을(vs. 높을) 때 브랜드 진정성을 통한 구매의도에 미치는 영향이 커졌다. 하지만 자발 참여형은 브랜드 인지도에 따라 구매의도와 브랜드 진정성에 미치는 영향이 상이하지 않았다. 이는 공익 마케팅의 효과를 높이기 위해서는 기업 주도형 보다는 자발 참여형이 더 유의함을 밝히는 결과이며, 기업 주도형 공익 마케팅을 진행하는 경우에는 브랜드 진정성을 높게 지각하게 할 수 있는 방안에 대해 모색하는 것이 공익 마케팅의 성공을 담보하는 길임을 시사한다.

Because of explosive growth in demand for web-based multimedia applications, proper proxy caching for large multimedia object (especially video) has become needed. For a video object which is much larger in size and has different access characteristics than the traditional web object such as image and text, caching the whole video file as a single web object is not efficient for the proxy cache. In this paper, we propose a proxy caching strategy with the constant-sized segment for video file and an improved proxy cache replacement policy. Through the event-driven simulation under various conditions, we show that our proposal is more efficient than the variable-sized segment strategy which has been proven to have higher hit ratio than other traditional proxy cache strategies.

This study aimed at the analysis, from the perspective of rationality, of policy making process in the separation of prescribing and dispensing. This study is to identify the characteristics and problems of the policy process to introduce the new durg-prescription system, and make policy recommendations. In terms of separation of prescribing and dispensing, the development of policy making process can be divided into two periods; periods before and after the inauguration of the govemment of people. In the period before the govermment of poeple, one of the major characteristics of policy decision on the new system was the poweful influence of interset groups. At that time, the ministry lacked the problem-solving ability and commitment on the policy. Consequently, during the former period, the policy making process had been driven by interest groups. Therefore, the original purpose of the policy to secure the pulic health was lost. During the latter period, there was also the strong influence of interst groups, complexity of interest, the ministry's inability of problem solving. However, in this period, it is notable that this has drawn nation-wide attention, severl civic grouos have participated in the policy making process, and that the number and voice of these groups have remarkably increased. With regards to rationality, incrementalish model is highly sutable to explain the policy making process in the former period. But in the latter period when the new drugperscripition system became a national issue and civic groups began to participte in this matter more actively, rational model is more explanatory that incrementalism to understand the process. During the latter period, the original goal of this policy was not distored by a few interest groups thanks to the rapid development of civil movement and therebly a big influence of civic groups on the policy making. For that reson, a jigh level of rationality is found in the policy-making process of the latter period. Some suggestions to achieve the rationality in the policy making process based on the results of this study are as follows; Frist, the public's participation should be enered in the policy making process. Second, the govermment should make contiuns efforts to enhance its ability of long-term planning and policy implementation, and increase rationality of policy making process. Third, balance among interset groups should take place in the process of policy making. Forth, sound, constructive, and logical activity of interest groups is necessary to express and promote their interests.

대학도서관은 구성원이 교육과 연구를 수행하는 데 있어 필요수적인 자료를 선정하여 구입할 필요가 있다. 따라서 이용자의 정보 요구를 장서 개발에 반영하는 방법으로 희망도서 제도를 운영하고 있다. 본 연구는 10년간의 장기적 관점에서 희망도서 신청 과정과 결과를 분석하였다. 희망도서는 단행본에 대한 강력한 정보 요구이기 때문에 주제 분야별 이용자의 정보 요구 패턴을 파악할 수 있었다. 대학 구성원으로서 이용자는 전공하는 학문 분야에 대해서는 전공 도서를 선정하면서도 다른 주제 분야의 교양 도서를 적절히 선정하여 장서 구성에 기여하고 있었다. 결과적으로 희망도서는 소수의 이용자에 의해 선정이 이루어지지만 도서관 전체 이용자의 정보 요구를 충족시키고 있어 효율적인 장서 개발 정책으로 운용되고 있다고 볼 수 있다.

본 논문은 지표분석법을 활용하여 중국 정부의 소프트웨어 지원정책이 소프트웨어 수출액에 미치는 영향을 분석하였다. 2008년부터 2014년까지 기술개발, 인력양성, 품질관리, 마케팅강화 측면에서 분석한 결과, 연도별 정책영향력과 소프트웨어 수출액이 비슷한 모양으로 증가하였으며, 이것은 중국 정부의 소프트웨어 지원정책이 소프트웨어 수출액에 정비례적인 효과가 있음을 의미하고 있다. 다만, 중국 소프트웨어 수출액이 소프트웨어 총생산액에서 차지하는 비중은 매년 하락했으며, 이것은 중국 소프트웨어산업이 내수시장 위주로 성장하고 있음을 시사하고 있다. 이러한 중국의 소프트웨어 지원 정책과 시장추이를 고려하여 한국 정부는 빅데이터, 사물인터넷 등 미래전략산업의 경우 국내 활성화를 바탕으로 중국 시장 진출을 확대하고, ICT와 제조업, 서비스업간 융합 신사업의 경우 한 중 양국의 비교우위를 결합하여 상호이익이 될 수 있는 적합한 모델구축이 필요하다고 본다.

The purpose of this empirical study is to test hypotheses in order to identify the cost drivers that drive indirect costs in general hospitals in Korea. In various cases' studies, it has been suggested that overhead costs are driven by volume and complexity variables, how they are structurally related and how the cost impacts of these variables can be A unique feature of the research is the treatment of complexity as an endogenous variable. It is hypothesized that level of hospital complexity in terms of the number of services provided(i.e., “breath" complexity) and the intensity of individual estimated in practice. overhead services(ie., “depth" complexity) are simultaneous determined with the level of costs needed to support the complexity. Data used in this study were obtained from the Database of Korean Health Industry Development Institute, Health Insurance Review Agency and analyzed using simultaneous equation model, path model. The results found those volume and complexity variables are all statistically signi-ficance drivers of general hospital overhead costs. This study has documented that the level of service complexity is a significant determinant of hospital overhead costs, caution should be exercised in interpreting this as supportive of the cost accounting procedures associated with ABC. with ABC.

Bluetooth is an emerging technology expected to provide users with short range, low cost, pico-cellular wireless connectivity. The access to the medium for Bluetooth is based on a Master driven Time Division Duplexing (TDD) scheme. A slave transmits packets in the reverse slot only after the master polls the slave (or transmits a packet to the slave) in a forward slot. The master transmits packets to a slave in even slots while the slave transmits packets to the master in an odd slot. The way in which the master schedules packets transmission to slaves or polls them determines system performance. In this paper. we propose a traffic adaptive MAC scheduling scheme for Bluetooth. The proposed scheme adopts the ISAR (Intelligent Segmentation and Reassembly) policy, which adjusts the packet size to the traffic patterns, to adapt the polling frequency to the traffic conditions. Also for achieving fairness among master-slave connections our scheme includes a priority policy assinging prioritised service tlimes to each connection. By considering a scenario where a Bluetooth master is used as wireless access point to the Internet, we show that our scheme improve the system throughput and average queue delay with regard to a naive Round Robin (RR) scheme.
