According to the previous study, after 2000s, factors of the Chinese government's trade policy changes would be a significant burden on the company. However, many previous studies were limited to the response strategy by judicial analysis. Therefore, this study aims to analyze the factors that affect the export performance of Korean manufacturing companies in China. Also, by using that result, I would like to provide advises for entered the korean companies in Chinese market As the results, I knew that export performance are most heavily influenced by labor policy factor and the fallowing is exchange rate policy factor. Eventually, Most of our country companies entering in china were affected changes in the exchange rate policy factor, but many company were manufacturing-type businesses to economize labor costs. Therefore, corporate and governmental response strategies are needed for that's companies.

Since government institutions begin working 40 hours each week, public libraries in Korea face the challenge of not only enhancing the quality of life for librarians by improving their work environment, but also providing adequate information services for patrons. The purpose of this study is to examine the potential problems which could happen with the 40 working-hours each week in public libraries, and establish the strategies for resolving these problems. For this study, based on the existing research, an attempt is made to review and analyze the following facts: (1) the details of planning for 40 working-hours each week at the government institutions in Korea; (2) the current work environment and service strategies of public libraries in other countries, including the U.S., where librarians work 40 hours each week; (3) the present state of managing public libraries with 40 working-hours each week in Korea; and (4) the strategies of public libraries as a part of cultural infrastructure in preparing for 40 working-hours each week which will be fully implemented at the government institutions in Korea.

The importance of the life cycle cost analysis(LCCA) for apartment housing remodeling projects has been fully recognized over the last decade. Accordingly theoretical models, guidelines, and supporting software systems were developed for the life cycle cost analysis of apartment housing remodeling systems. However, the level of consensus on LCCA results is still low due to the lack of reliable data on remodeling activities for safety diagnosis. in order to predict the reliability based LCCA of the given case, suggested the remodeling strategies level after reviewing other related materials. Apply the real information of the economic index. And based on such analytical measures, remodeling and operation cost and LCC in remodeling strategies level have been predicted; suggests the basic information about remodeling interventions level for the apartment housing. The LCC analysis models and the fuzzy logic based safety assessment presented in this study can greatly contribute to the value-oriented design alternative selection, estimation of the economic analysis, and the allocation of budget for apartm.

This study investigates the effect of diesel combustion strategies on exhaust emissions and hydrocarbon species emissions for a 1.7 L common rail direct injection diesel engine at 1500 rpm and 3.9 bar BMEP. The first strategy is a method to adopt no EGR with a split injection composed of pilot and main injection (split injection). The second is to adopt a moderate EGR rate with main injection only (single-1). The third is to use a high level of EGR and main injection with rail pressure increase, $i.e.$ low-temperature diesel combustion (single-2). Split injection and single-1 showed a renowned phenomenon of a PM-NOx trade-off, whereas single-2 was observed of a PM-NOx trade-off to reduce PM and NOx simultaneously. HC speciation results show that the split injection produced the least amount of HC species, regardless of the carbon number bin, followed by single-1 and single-2. The ratios of methane, acetylene, and CO to THC increased as a combustion A/F ratio is richer due to reduced oxygen content in the vicinity of the combustion zone, thus enhancing pyrolysis.

The effects-based operation, which would reduce unnecessary efforts and meaningless sacrifices incurred during a war and simultaneously reach the will of the enemy leadership by strategic attacks, was discarded for the reason that it was difficult to apply it to military power except for airpower. However, cyberspace, which can be thoroughly logical and calculated, can be suitable for conducting effects-based operations. This study examined a way to carry out effects-based operations in such cyberspaces. It laid the foundation for overcoming the limitations of effects-based operations revealed in previous battle cases and executing the operations in cyber battlespace where the boundary between physical and cyberspaces gradually disappeared. Futhermore, it demonstrated that effects-based operations could be carried out in cyberspace by establishing a military strategy, which could conduct the operations through an analysis of previous cyber-attack cases.

The public Information systems for destination marketing have poorly operated and failed to satisfy tourists' needs. Public tourism website mainly offers fundamental tourism information such as transportation, lodging and prime attractions, which is mainly specialized in commercial web sites, and fails to attract tourists. For the public benefits, marketing strategy publicl DMOs have to specialize their tourism information, and attract specific target markets. Thus, this study examined the effect of tourism motivations on information search behavior to figure out the importance of tourism information. The results show that the level of escapist motivation positively to the perceived importance of fundamental informations, and the level of activist motivation effects positively to the perceived importance of objective-specific informations. These results give show problems of regional tourism information site and implications are suggested.

Stratification is a feature of the majority of field sample design. This paper considers the multivariate stratification strategy for multipurpose sample survey with several auxiliary variables. In a multipurpose survey, stratification procedure is very complicated because we have to simultaneously consider the efficiencies of stratification for several variables of interest. We propose stratification strategy based on factor analysis and cluster analysis using several stratification variables. To improve the efficiency of stratification, we first select the stratification variables by factor analysis, and then apply the K-means clustering algorithm to the formation of strata. An application of the stratification strategy in the sampling design for the Fisher Production Survey is discussed, and it turns out that the variances of estimators are significantly less than those obtained by simple random sampling.

외환위기 이후 IT는 우리 경제의 견인차로 인식되어 왔으나 2000년대 초두의 IT 버블 붕괴 이후 극심한 성장정체를 겪으면서 일부 학자 및 정책입안자를 중심으로 IT 역할에 대한 회의론적 시각이 제기되어 왔다. 그러나, 지난 2~3년간의 각종 경제지표를 볼 때, IT는 여전히 우리 경제에서 중요한 역할을 하고 있음을 확인할 수 있을 뿐만 아니라 미래사회에의 대응을 위해서도 IT에 대한 관심 제고가 무엇보다도 절실한 시점이라 하겠다. 특히, 스마트폰의 등장에 따라 스마트폰 환경에 최적화된 다양한 애플리케이션의 등장과 이를 이용한 모바일 서비스의 보급 확산으로 IT 기기 및 서비스 산업의 경쟁구조에 근본적인 변화가 발생하면서 IT 강국이라는 국가적 브랜드마저 위협받고 있는 시점이어서 더욱 그렇다. 스마트폰의 등장으로 국가경쟁력 결정 패턴이 노동과 자본 등 전통적인 생산요소에 기반한 개별 산업분야의 경쟁우위를 기초로 결정되던 형태에서 감성과 창의성 등 소프트 파워의 보유 정도에 따라 결정되는 형태로 전환되었다는 점에서 R&D전략에 있어서도 중요한 전환점을 맞고 있다고 보여진다. 또한, 산업사회와 정보사회에 이어 급격한 기술혁신에 따른 기술간 및 산업간 융합의 정도가 산업 전반의 경쟁구도에 영향을 미칠 것으로 대부분의 전문가들이 예견하고 있으나, 산업현장이나 기술분야에서 실제적으로 발생되는 융합의 양상은 그다지 신속하지 못한 것으로 나타나고 있다. 따라서, 기술간 및 산업간 융합촉진을 통한 전산업 경쟁력 제고를 위한 R&D 방향 모색이 필요한 시점이다. 이에 따라 본고에서는 스마트폰의 등장에 따른 IT산업의 경쟁구도 변화와 글로벌 기업들의 전략, 대응방향 등을 살펴보는 한편 IT의 전반적인 활용도 증가에 따라 더욱 가속화될 것으로 전망되는 기술간 및 산업간 융합시대에 대응한 IT R&D 방향을 살펴본다. 이는 궁극적으로 IT 강국이라는 국가적 브랜드 이미지의 고착화 전략인 동시에 IT 기반의 융합을 촉진시킴으로써 스마트한 IT Korea라는 국가적 미래비전을 달성해 나가기 위한 방향이 될 것이다.
