This research analyzes results and efficiency to promote a government enterprise of A Korean public enterprise to use DEA. Especially, we were used analysis efficiency which are one is year-on-year, another is integrated, and the other is vertical analysis. As a results of integrated analysis show that Gyeonggi_2003 Gyeonggi_2004, Gangwon_2004, Chungcheon-Bukdo_2003, Chungcheon-Bukdo_2004, Cholla-Namdo_2005, and Kyongsang-Bukdo_2003 need to improve upon. Year-on-year analysis result that Gyeonggi, Gangwon, and Kyongsang-Bukdo need urgent improvement. Today, many advanced countries approach not only agricultural investment but also synthetic investment because they believe that agriculture contains living space including food control. Therefore, when the government make a strategic plan for the land and water development in the field of agriculture, they should prepare it well including the proper measures to cope with the internal and external environments.

우리나라는 세계 최고 수준의 IT 인프라를 기반으로 네트워크 및 서비스 융합, RFID 등 u-IT 서비스 확산 등을 통해 유비쿼터스 사회로 빠르게 진입하고 있다. 향후 디지털 융합이 가속화됨에 따라 시간과 공간의 제약 없이 원하는 정보의 획득 활용이 증가하고, u-Health, u-learning 등 IT가 타산업과 융합되면서 높은 부가가치를 창출할 것으로 전망 된다. 그러나 정보화의 급속한 진전에 따른 사회 전반의 편의성과 효율성이 향상하였으나, 해킹 바이러스, 개인정보 유출사고, 스팸 등 역기능으로 인한 피해도 확산되고 있다. 최근에는 네트워크 방어체계를 무력화시키는 지능화된 해킹, 대량의 고객정보 유출, 사회공학 기법을 활용한 피싱 등 이용자의 자산과 프라이버시를 침해하는 사이버범죄 증가 등으로 이용자자산과 권리 보호관점에서의 정보보호의 중요성이 부각되고 있다. 향후 시간과 장소에 상관없이 지식정보를 활용하여 편리하고 쾌적한 생활을 누리게 하는 지식정보사회는 예측 불가능한 위험이 곳곳에 산재한 정보위험사회로의 진입을 의미 할 수도 있다. 그러므로 미래사회에서 예상되는 위협을 예측하여 효과적으로 사전에 예방할 수 있는 체계를 마련하는 것은 안전하고 신뢰할 수 있는 지식정보사회를 향유하기 위한 전제조건으로 작용한다. 이에 본고에서는 미래 지식정보사회에 대비한 정보보호 전략으로 안전한 u-사회 청사진 설계 및 환경조성 선도와 국제화, 사이버위협 예방 및 대응체계의 입체적 조화와 융합, 정보보호 기술 제품 산업간 선순환 촉진과 성장 등 3대 전략을 설정하고 실행방안을 제시한다.

핵융합반응은 초고온의 플라즈마 상태에서 가벼운 원자핵들이 융합하여 무거운 원자핵으로 바뀌는 현상으로, 이 과정에서 감소된 질량이 막대한 에너지로 변환되는데 이를 핵융합에너지라고 한다. 핵융합에너지는 인류의 에너지 위기를 극복할 수 있는 최적의 대체에너지이며, 무한, 청정, 고효율에너지이다. 이에 국가핵융합연구소(NFRI)는 Green Energy 의 개발과 핵융합에너지 상용화 기술을 개발하기 위해 핵융합연구장치인 KSTAR(Korea Superconducting Tokamak Adavanced Research)를 제작하여 장치의 운전연구 및 기술 확보에 힘을 쏟고 있다. 또한 핵융합 관련 파생기술을 활용한 첨단 신사업 창출에 기여하고 있다. 본 논문에서는 KSTAR 1st Plasma 실험 시 KSTAR 장치에 전력을 공급하기 위한 전력설비 현황, 전력품질분석, 전력사용량 분석을 통해 향후 KSTAR 장치 운전을 위해 필요한 수전설비 증설, 무효전력보상장치 증설 등과 같은 전력계통의 효율화와 안정화를 위한 개선사항에 대해 기술하였다.

Recently, a new distributed grid scheme, called DS-GRID(distributed S-GRID), has been proposed to manage the location information of moving objects in a spatial network[1]. However, because DS-GRID uses uniform grid cells, it cannot handle skewed data which frequently occur in the real application. To solve this problem, we propose a dynamic distributed grid scheme which splits a grid cell dynamically based on the density of moving objects. In addition, we propose a k-nearest neighbor processing algorithm for the proposed scheme. Finally, it is shown from the performance analysis that our scheme achieves better retrieval and update performance than the DS-GRID when the moving objects are skewed.

XML is recommended by W3C(World Wide Web) and widely accepted as a standard markup language for expression and sharing data. Recently, increasing the use and the amount of XML documents, there is required that easy methods for accessing XML documents at anytime and anywhere, therefore, the distributed XML repository systems is developed. For this, distributed XML repository systems is necessary to research catalog management schemes. In this paper, we design distributed XML database model considering CPU costs, I/O costs, concurrency control, two-phase commits a protocol, queuing delay and so on. And we implement a simulator in order to execute performance evaluation centralized catalog method, fully replicated catalog method, and partitioned catalog method using reasonably setting up environments.

In recent, the Korean fisheries industry face an overall crisis. Annual fish catch is continuously decreasing for last two decades even though various programs to improve fish population. Moreover, domestic fish market is more and more occupied by imported cheap fish products from abroad due to the consequence of open economic policy, FTA and WTO/DDA entente. Under the circumstances, this study aims to examine the potential for building fisheries cluster as a policy tool to promote fisheries and fisheries-associated industries in Korea. To achieve this goal, the authors firstly reviewed the theoretical concept of Industrial Cluster in the evolutionary economics point of view, secondly, analyzed the main components of Porterian Cluster(or innovation cluster), thirdly, derived the key reasons to induce the improvement of productivity within the cluster network system and lastly evaluated fisheries capability and industrial infrastructures of each province as a basic condition to build a fisheries cluster. The result of the study demonstrates the voluntary accumulation of fish products and processing techniques in Korea, however, it is not enough to make up a Porterian innovation. Therefore, the present is most opportune for applying fisheries cluster as a strategic policy tool. Government supports to establish innovation cluster for fisheries may contribute both fisheries industry and local economy by developing the latent capacity of fisheries and helping concentrate innovation capabilities.

Purpose: The purpose of this study was to identify the predictors of Quality of Life (QOL) among workers in public health corporations. Methods: Data were composed of 213 office workers in three public enterprise in Seoul. Data were collected from February 11 to March 20, 2007. Data were analyzed with descriptive statistics, t-test, ANOVA, Pearson correlation and stepwise multiple regression using SPSS Win 12.0 program. Results: The mean QOL of the study participants was 82.60. The QOLs of the workers were significantly different according to perceived health status of workers and working hours per week. The QOL of the workers was negatively related to working hours, job stress, and depression, and positively related to the health status, self-esteem, and health promotion lifestyle (HPLS). Significant predictors of QOL were HPLS ${\beta}=.420$), depression (${\beta}=-.291$), self-esteem (${\beta}=.261$), and hours of work per week (${\beta}=-.114$), which explained 63% in the variance of QOL. Conclusion: These results suggest that strategies to enhance HPLS could improve the level of QOL. Further investigations of the direct relationship between QOL and health promotion program is warranted.

This paper provides a new approach for predicting the corrosion resistivity of reinforced concrete structures exposed to carbonation. In this method, the prediction can be updated successively by a Bayesian theory when additional data are available. The stochastic properties of model parameters are explicitly taken into account into the model. To simplify the procedure of the model, the probability of the durability limit is determined from the samples obtained from the Latin hypercube sampling technique. The new method may be very useful in designing important concrete structures and help to predict the remaining service life of existing concrete structures which have been monitored.

The objective of this study is to analyze the causal relationship among Non-profit Criteria of the Malcolm Baldrige National Quality Award(MBNQA) and to compare the casuality among company, hospital and non-profit organization field. The survey instrument consists of 94 questions from the seven categories of the MBNQA. Structural Equation Modeling (SEM) is used to analyze the empirical data and estimates the path coefficients among the MBNQA categories. The result of our research is as follows, First, the Leadership effects on as a driver of all factors. Secondly, the positive effect of the Foundation on the Direction and the System categories, Finally, the positive influence of the Direction on the System categories of the MBNQA model. In this study, most hypothesis are statistically significant.
