The purpose of this study was to determine the satisfaction and return impact of the Festival visitors visiting the food and art festivals in Suncheon city. which successfully hosted the Suncheon Bay Garden Expo.. In order to carry out this research, hypothesis was set up, and after the questionnaire survey was conducted for the visitors participating in the festival, empirical analysis was conducted through the survey. Also, I would like to present the implications for the tourism development process and the convergence research of the fourth industry for the garden and food tourism of the tourists coming back again in the future due to the festival. The effect of factors on festival satisfaction was found to be influential in order of tourism product, food, guide and public event program. Also products and food facilities. It was confirmed that the guide and publicity part had an influence on the revisit of the festival and also the recommendation of the festival. As a result, the attributes of satisfaction factor of Suncheon Food & Art Festival were confirmed and causality was derived because visitors' satisfaction had positive influence on behavior intention. However, the limitations of the study remain in that it does not reveal the subdivision factors of the satisfaction and perceived satisfaction in measuring the festival satisfaction.

This study analyzed the related factors affecting to perceived gastritis or perceived enteritis for 11,753 Korean high school seniors who participated in the 2009 Korea Youth Risk Behavior Web-based Survey (KYHRBWS). Of the subjects, 5,685 (47.6%)were male and 6,068(52.4%) were female and 8.7% of the students responded that they had suffered from gastritis or enteritis for a long time and the females had a slightly higher attack rate of gastritis or enteritis. Survey logistic regression models and decision tree analysis were used to calculate odd ratios and 95% confidence intervals. As a result, there was affecting to their stress and health behaviors in the risk of gastritis and enteritis, and that their lower level perceived health, smoking, heavy drinking or starting drinking before they were 13 years old and a higher level of perceived stress significantly affected the risk of gastritis or enteritis in the subjects(p<.001).

The development and operation of the MASS (Maritime Autonomous Surface Ship) is being actively discussed for more efficient and safer maritime transportation solutions. The autonomous navigation technology has positive aspects such as the prevention of marine accidents, improvement of fuel efficiency of ships and cost reduction, and negative aspects such as job loss, task change, and security problems. It is expected that there will be new human element issues such as the situation awareness of remote operators, because the shore-based control will be conducted when fully autonomous ships are in operation. In this paper, we consider major human element issues that should be factored in the development and operation of MASS, and suggest a method of HRA (Human Reliability Analysis) for P IFs (Performance Influencing Factors) of the remote operators that are expected according to the shore-based control.

The ICT industry has been the main driver of Korea's economy with international competitiveness and is expected to be the growth engine that will revitalize the currently depressed economy. A broad range of different perspectives and opinions on the industry exist in Korea and overseas. Some of these are stereotypes, not all of which are based on objective evidence. Stereotypes refer to widely-held fixed opinions on a specific group and do not necessarily have negative connotations. However, they should not be viewed lightly because they can substantially affect decision-making process. In this regard, this study sought to review the stereotypes of ICT industry and identify objective and relative stereotypes. In the study, a decision-tree analysis was conducted on a survey result of 3,300 small and medium-sized enterprises (SMEs) in order to identify Korean ICT companies' characteristics that distinguish them from other technology companies. The decision-tree analysis, a data mining process based on machine learning, took a total of 291 variables into account in 10 subjects such as: corporate business in general, technology development activities as well as organization and people in technology development. Identifying the variables that distinguish ICT companies from other technology companies with the decision-tree analysis, the study then came up with a list of objective stereotypes of ICT companies. The findings from the stereotypes of Korean ICT companies are as follows. First, the companies are in need of technology policies that help R&D planning and market penetration. Second, policies must better support the companies working to sell new products or explore new business. Third, the companies need policies that support secure protection of development outcomes and proper management of IP rights. Fourth, the administrative procedures related to governmental support for ICT companies' R&D projects must be simplified. It is hoped that the outcome of this study will provide meaningful guidance in establishment, implementation and evaluation of technology policies for ICT SMEs, particularly to policymakers or researchers in relevant government agencies who determine R&D policies for ICT SMEs.

This research takes a user-centered approach to define relevance, the core concept in information retrieval. The literature on relevance has identified numerous factors affecting such a judgment. We examined the model of user relevance judgment that describes the relationship between user relevance criteria and different types of relevance with information search task. We consider 7 criteria of user relevance-topicality, novelty, reliability, understandability, specificity, richness, and interest-and 3 type of user relevance-cognitive relevance, situational relevance, and affective relevance. Data were collected from a semi-controlled survey and analyzed by a structural equation modeling. As a result, topicality and reliability were found to be the essential relevance criteria in all information retrieval tasks. In the fact search task, topicality, reliability, novelty, richness, and interest were found to be significant. In the problem solving search task, topicality, reliability, understandability, and specificity were found to be significant. In the decision making search task, topicality, reliability, novelty, understandability, richness, specificity, and interest were found to be significant. In addition, the relationships between types of user relevance were determined. This research made theoretical and practical contributions to the field of information retrieval by identifying a definite model of user relevance judgment.

Since 2002, Korea Government has introduced Green Standard for Energy and Environmental Design Certification for reducing GHG emission in building area. However, total number of G-SEED Certification is only around 1% of total number of approved apartment buildings despite the various boosting policies. In this situation, most boosting policies and policy improvement researches are leaning toward the supplier's aspect. However, comprehensive relation and dynamics between consumer and supplier has to be considered because housing market is operated by market participants' mutual interaction. Therefore, this research presents system dynamics models based on decision making analysis of consumer and supplier in G-SEED Certification apartment building market. Then, this research evaluate the validity of boosting policies using the model. The proposed analysis can assist government to make next G-SEED Certification boosting policy.

This paper purports to explain the conflicts and compromises between supra-national authority and national welfare state in an era of globalization. For this purpose this paper, first of all, examines if Community law(EU) is directly applicable to member states(direct applicability), and subsequently, if Community law is superior to national law(supremacy). It duly claims that Community law is de facto applicable to member states and thus is superior to national law, but de jure the direct applicability and supremacy of Community law are still ambiguous in practice. Secondly, it briefly describes the development of EU social policy from 'The Rome Treaty(1957)' to 'The Amsterdam Treaty(1997)', and ascertains clear limitations of social dimension of EU. Thirdly, it explains why CEU(Commission of European Union) sequently fails to achieve uniform harmonization policy in the making of social Europe. This paper concludes that 'downward harmonization thesis' or 'convergence thesis' which commonly stresses that globalization seriously impinges on nation-state's policy autonomy and policy capacity is not evidenced at least in the case of EU social policy.

Global warming due to increased carbon dioxide is perceived as one of the factors threatening the future. Efforts are being made to reduce carbon dioxide emissions in each industry around the world. In particular, environmental loads and impacts during the life cycle of SOC structures and buildings have been quantitatively assessed through a quantitative method called Life Cycle Assessment (LCA). However, the construction sector has gone through difficulty in quantitative assessment for several reasons: 1) LCI DB is not fully established; 2) the life cycle is very long; 3) the building structures are unique. Therefore, it takes enormous effort and time to carry out LCA. Rather than estimating carbon emissions with accuracy, this study aims to present a simplified estimation model that allows owners or designers to easily estimate carbon dioxide emissions with little effort, given that rapid and rough decisions regarding environmental load reduction are to be made. This study performs the LCA using data from 25 road construction projects across the country, followed by multiple regression analyses to derive a simplified carbon estimation model (SLCA). The study also carries out a comparative analysis with values estimated by performing a typical LCA. The comparison analysis shows an error rate of less than 5% for 16 road projects.

This study used age, education, major, working period as CEO's characteristics and examine relationship between these characteristics and R&D Investment. Furthermore this study examined how CEO should react in terms of R&D investment, which is effected by CEO's characteristic in the market. The empirical results are following. (1) When CEO's age are young, they spend much money for R&D investment. And R&D investment which is determined by young CEO has a positive effect on relation of firm value. (2) A higher educational background has a positive effect on R&D investment and will create higher firm value. (3) When CEO's major is competitive in the same industry, it has a positive relationship with R&D investment and its firm value is bigger than though. (4) When CEO working period is long, they showed active to R&D investment. On the other hand, the firm value decreased. This study focused on analyzing the relationship between characteristics of CEO and R&D Investment, furthermore, how R&D investment which effected by CEO's characteristic is contributing in creating the firm value. This results indicate that CEO's characteristics reflect R&D investment and value of venture business. Therefore, CEO's characteristics should be considered financial information and firm value in the market.
