Conducting a large-scale survey to tenants of domestic business incubators(BI) in diverse growth stages, this study investigates the level of importance, satisfaction, and expectation-fulfillment perceived by tenants on various services of BI. Results of the study show that highly ranked BIs' support services in terms of importance and satisfaction levels perceived by tenants in various growth stages are quite different than highly ranked BIs' support services in terms of the expectation-fulfillment level which is measured by the gap between the level of perceived importance and satisfaction. Such findings should help BI formulating effective support and resource allocation strategies.

Recently, interest in virtual money has been growing. There is also a view that it is safe to pursue traditional assets, and some wealth experts are expecting positive changes in the financial society that can be diversified due to virtual money. Since the virtual money market is an immature situation and the stability of the virtual money is not yet secured, the potential risk of the transaction of the virtual money is highly likely to occur. In this study, we try to derive important priorities by deriving the evaluation factors that can contribute to the stabilization of the virtual currency in the market transaction. The main evaluation factors were selected from the viewpoint of the transaction environment, the technical viewpoint, and the profit viewpoint, and the importance of the subordinate factors was analyzed by applying AHP.

As the resources of cloud computing are essentially heterogeneous and jobs have various characteristics, resource allocation to jobs is one of important problems. We define this issue as a multi-criteria decision-making problem. This paper proposes a priority-based job scheduling algorithm based on analytic hierarchy process (AHP). On the first step, jobs are classified based on their preferences. On the second step, response time, system utilization, and load becomes decision criteria based on the AHP algorithm. Jobs are allocated to adequate resources through their priorities that are calculated by the AHP algorithm. Through analysis and experiment of the proposed algorithm, we are to confirm that the scheme can schedule jobs as well as utilize its resource efficiently.

Risk ranking must be determined for various hazards/food combinations to conduct microbial risk management effectively. Risk Ranger is a simple, easy-to-use calculation tool developed in Microsoft Excel and designed to rank the risk (low, medium, and high) for semi-quantitative microbial risk assessment. The user is required to answer 11 questions in Risk Ranger related to 1) severity of the hazard, 2) likelihood of a disease-causing dose of the hazard being present in the meal, and 3) the probability of exposure to the hazard in a defined time. This study determined the risk ranking for twenty three combinations of foodborne pathogens/potentially hazardous foods (PHFs) using a Risk Ranger. In this study, pathogenic E. coli in fresh cut produce salad was scored as 79, which was the highest rank among the 23 combinations of the foodborne pathogens and PHFs. On the other hand, zero risk was obtained with V parahaemolyticus in sushi, Salmonella in meat products and E. coli O157:H7 in hamburger patties. Although Risk Ranger is very simple method to rate the risk of foodborne pathogens and PHFs combination, the accuracy of result was mainly affected by the availability and accuracy of data in the literature. According to the result of literature review, the data are needed for contamination rate of raw materials, consumption amount/frequency of PHFs, and the effect of processing on pathogen. Risk ranking must be continuously revalidated with new data.

본 연구는 농천어메니티의 개념을 토대로 농촌주민과 도시민의 가치라고 할 수 있는 정주기능으로서의 생활자원화와 방문가치로서의 관광자원화로 구분하고, 이를 토대로 도시민과 농촌주민, 전문가들을 대상으로 농촌자원의 중요도와 순위적 관계를 분석하였다. 구체적인 연구결과를 살펴보면 다음과 같다. 첫째, 농촌자원을 자연적 자원과 문화적 자원, 사회적 자원으로 구분하여 37개 자원을 설정하였다. 이러한 농촌자원은 농촌어메니티를 형성하거나 형성에 영향을 미치는 대상이라고 볼 수 있다. 둘째, 이러한 농촌자원은 농촌주민과 도시민이 지닌 가치에 기초하여 생활자원적 가치와 관광가치적 가치를 동시에 혹은 차등적으로 지닐 수 있다. 이러한 관점은 농촌자원에 대한 중요도 평균에 대한 차이검증(t-test)을 수행한 결과 전체 자원의 56.8%에 해당하는 21개가 유의미한 차이를 보인 결과에 의해 지지를 받는다. 셋째, 농촌자원에 대한 순위적 상관관계분석에서도 전문가와 전체집단에서 생활자원과 관광자원에 대한 순위상관관계가 의미가 없는 것으로 나타나 위의 두번째 결과를 지지하고 있다. 이러한 결과는 농촌자원의 개발 방향과 가치부여가 자원의 속성에 따라 차등적으로 진행되어져야 함을 보여준다. 다섯째, 농촌자원의 유형을 생활자원화와 관광자원화에 대한 중요도의 표준화 점수에 기초하여 4개 유형(유형 I~IV)으로 구분하였다. 이러한 유형별 자원중요도를 고려하여 농촌마을의 개발목적에 비추어 생활자원형이나 관광자원형과의 연계를 통해 마을의 정체성과 특성화에 기여할 수 있도록 해야 할 것이다.(요약 및 결론에서 발췌)를 고지도와 지리지.읍지를 통하여 살펴봄으로써 변한 것과 변하지 않는 것을 분석하여 시대상의 복원과 지역사회의 정체성 확립에 일조하고자 한다.곡물의 여러 줄기가 합수하고 물이 역류하지 않으며 잘 감아도는 곳으로 표현할 수 있다 이러한 명당의 기본적인 원리는 장풍(藏風)과 득수득파(得水得破)이다. 장풍과 득수란 '국'(局), 즉 산줄기와 수계로 이루어진 일정한 범위 속에 만물이 생태계 속에서 살아가는 모습인 '체형(體形)'의 의미가 나타나야 한다는 것이다. 그러나 이러한 의미는 시대에 따라 달라질 수 있는 것이다.면적의 52%를 점유하여 감자 재배지의 핵심지를 이룬다. 4. 한국 감자 재배지역 중심지의 지리적 특징은, 높은 산지지역의 산록완사면에 밭작물로 재배된다는 점과 교통이 불편한 지역으로서 도시화와 산업화 지역의 그늘 지역이 대부분이다. 강원도의 감자 재배지는 감자재배에 적합한 자연환경과 화전농업의 전통, 감자 재배기술의 전파, 중앙정부와 지방정부가 지원하는 각종 연구소 분포와 영농지도, 씨감자 생산과 협동조합의 판로 개척, 도로 개설과 포장 등의 인문지리적 요인이 영농조건을 개선하고 감자 판매를 위한 시장접근을 용이하게 하여, 남한 최대의 감자 재배지역을 형성하였다. 제주도는 산지지형과 따뜻한 기온으로 2기작이 가능하고, 감자가공 공장설립과 교통발달에 따른 육지 시장과의 접근이 용이해졌기 때문에 남한에서 2번째로 큰 감자재배지역이 되었다.(요약 및 결론에서 발췌)그람양성균에서 효과적이었으며, 농도별 항균력시험 결과 농도가 증가할수록 비례하여 저해율도 증가함을 알 수 있었다. 첨가농도를 달

The present study investigated individuals' perception of important social issues in Korea. Based on previous research(Hahn, 1994; Hahn & Kang, 2000), a checklist containing 370 social issues was created. This checklist was administered to 1600 Koreans(812 college students, 788 adults) residing in 5 regional areas in Korea during the period of December 2004 and February 2005. Data were analyzed by the respondents' age, sex, and residing areas, and findings were compared to those of the two previous studies conducted in 1994 and 1999. Major findings of the study are as follows. First, across the three surveys, over 50% of the respondents consistently indicated the following four items as important social issues in the Korean society: political corruption, environmental pollution, the education system that is driven too much for college entrance, employment difficulty for local college graduates. Second, more than 50% of the respondents in the current survey indicated the following 12 items as important social issues that must be resolved: high unemployment rate, political corruption, environmental pollution, education system, overall difficulty of getting jobs, the nation's distrust in politics, hardships of life among the working classes, political incompetence, people with defective personal credit standings, employment difficulty for local college graduates, political instability, corruption of public servants. Third, analyses on the top 30 social issues across the three surveys revealed a positive and significant rank-order correlation for a five-year period(i.e., 1994-1999, 1999-2004), but not for a ten-year period(i.e., 1994-2004). Implications of the study and directions for future research are discussed.

In this paper, we propose an efficient real-time scheduling method of multimedia tasks for decoding frames of MPEG-2 video streams. In our task model, each frame is decoded by a separate multimedia task. The decoding task for each frame is assigned to the priority according to the precedence and importance of frames in a video stream. We use a priority-based scheduling policy in order to effectively allocate the CPU bandwidth to multimedia tasks for MPEG-2 decoding. We show how to dynamically control the fraction of the CPU bandwidth allocated to each multimedia task according to the priority. The primary purpose of our scheduling method is to enhance the real-time performance of the multimedia system by minimizing the number of decoding tasks that have missed their deadlines while reducing the decoding times of these multimedia tasks. The performance of this scheduling method is compared with that of similar mechanisms through simulation experiments.

Risk management activity for successful defense R&D project should be done anticipatorily and consistently over the entire project period and there should be a priority for management depending on importance of the risk factors. In this study, we verified the reliability and validity through factor analysis for the risk factors selected by the Delphi technique. We also obtained the relative importance of risk factors with analytic hierarchy process (AHP) and decided to prioritize for comparison of domestic and overseas research. According to the study, we found that it is important to settle the requirements and to classify the scope of R&D. It is also considered significant to have reasonable schedule for completion and secure the necessary resources in the early stage of project. Unlike previous studies, it appeared the technical factors are critical elements as well for defense R&D project.

In most of mobility enhancing plans for the transportation disabled, decisions for the investment priorities are firstly made by the facilities that have lower installation rate or lower satisfaction rate; the decisions are made without analyzing the importance factor (path loading factor) between the facility installation rate and the satisfaction rate together. In this study, a novel method of finding causality between the exogenous latent variables and the endogenous latent variables is provided by using the Structural Equation Model (SEM). The results show that the most influential facilities for the transportation disabled are bus stops, crosswalks and sidewalks in order. Also, a curb height around bus stops, a smoothness of sidewalks and installation of crosswalks traffic light are identified as an important facilities for the Transportation disabled.
