This study investigate the effect of each type of search volume on the number of Facebook fans and the number of tourists. According to the hierarchy effect model, the effect of communication appears to be the sequentiality of cognition-attitude-behavior. Applying this theory, this study predicted that when consumers who have higher involvement and knowledge on specific cities through search behavior, they will be more active in information search through Facebook fan page subscription and will lead to direct tourism behavior. To verify the prediction, we examined the influences among search volume of Seoul shown in Google Trend, the number of fans of official facebook page named 'Seoul Korea', and the number of foreign tourists. As a result, the type of search keyword was divided into four categories: tourism attraction keyword, natural environment keyword, symbolic keyword, and accessibility keyword. The regression analysis showed that tourism attraction keyword and symbolic keyword have influence on Facebook fanpage 'Like'. In addition, facebook fanpage fan size have mediation effect between search volume and number of tourists. All in all, it would be useful to appeal to foreign tourists with a message that emphasizes tourism attraction and Korea-related contents.

As a potential approach for non-destructive testing of concrete structures, we evaluate the time-of-flight (TOF) ultrasound tomography technique In conventional X ray tomography, the reconstructed Image corresponds to the internal attenuation coefficient However, in TOF ultrasound tomography, the reconstructed Image is proportional to the retractive index of the medium Because refractive effects are minimal for X-rays, conventional reconstruction techniques are applied to reconstruct the Image in X-ray tomography However, since ultrasound travels in curved path, due to the spatial variations in the refractive index of the medium, the path must be known to correctly reconstruct the Image. Algorithm for determining the ultrasound path is developed from a Geometrical Optics point view and the image reconstruction algorithm, since the paths are curved It requires the algebraic approach, namely the ART or the SIRT Here, the difference between the computed and the measured TOP data is used as a basis, for the iteration process First the initial image is reconstructed assuming straight paths. It then updates the path based on the recently reconstructed image This process of reconstruction and path determination repeats until convergence The proposed algorithm is evaluated by computer simulations, and in addition is applied to a real concrete structure.

Over the past 20 years new and small firms have been identified as significant components of economic strategies for job and wealth creation. Implicit in these strategies has been the search for policies which will increase the supply of new firms, and will encourage established firms' growth. Yet the majority firms spend the whole of their economic life within the small firm sector. The aim of this paper is to suggest a multidimensional approach to the understanding of the comparative characteristics of the small firm by providing evidence as to the factors which describe firms of different sizes, regions and industries. And I discuss in the context of policy options for regional economic development in Korea. The results from the analyses are summarized as follows. The size of the small firms in the sample measured in terms of both number of employees and sales revenue are characterized by regions, export performance and R&D. There is also some indication that growing firms may develop more complex environment. These results are based upon a multi-dimensional analysis of the strategic profile of a sample of small firms using KIS. From this observation of the firms during the data collection period, this is a conclusion that I find intuitively appealing.

This research analyzed determining factors of expenditure for processing fee by targeting trade show participants under a microeconomic approach in order to analyze determining factors of the participations of trade shows. As a result, with regard to the participation fees, income and the level of education seemed to be the socioeconomic factors that positively affected visitors in paying admission fees: and age and gender were negative elements. With regard to the participating businesses, the sales and the corporate history of the businesses were the positive elements to their willingness to pay the participation fees: however, the ratio of male and female personnel turned out to be a negative element in incurring the participation fees. The purchase of ticket was a positive mode-of participation factor to the visitors: however, distance tended to be a negative element for the visitors. For the participating businesses, the number of participation tended to be a positive element: however, distance was a negative one. The positive satisfaction factors that affected visitors' willingness to pay the participation fees included exhibited items, location, and schedules for events of the convention: for the participating businesses, the actual sales at the convention, the effects of advertisement and the level of satisfaction for location tended to play positive parts.

This study has analyzed on affecting factors of the customer's empathy toward the corporate philanthropic activities in terms of corporates and their products. From the corporate perspective, we have checked how the activities affect the perception of the customer familiarity and authenticity. Study shows that the fairness of the social contribution activities have an impact on both the familiarity and the authenticity (hypothesis 1, hypothesis 2). Social contributions reciprocity has been shown to influence familiarity (hypothesis 3) and it was not statistically significant to the authenticity (hypothesis 4). Looking at the relationship between the familiarity and authenticity from the product side, charm and familiarity (hypothesis 5), uniqueness and authenticity (hypothesis 8) showed that the impact on the definition. On the other hand charm and authenticity (hypothesis 6), uniqueness and familiarity (hypothesis 7) appeared to be not statistically significant. Finally, the relationship between familiarity, authenticity and empathy is as follows. First, the familiarity was found that it is affecting the authenticity (hypothesis 9) and for the consumer sympathetic (hypothesis 10) appeared to be not statistically significant. And the authenticity was found having a defined effect on the consumer sympathetic (hypothesis 11). It is really far more important to suggest an integrated approach to continue a sustainable and stable relationship by increasing consumer purchasing and empathy for the products and services of social enterprises. This study provides practical implications for marketing strategies of social enterprises, which can draw the consumer sympathy through the social contribution activities of social enterprise.

The purpose of this study is to examine the determinants of the number of bank relationships in Korea. Firm-specific determinants considered here include leverage, size, age, return on asset, investment grade, tangibility, liquidity, R&D expenditure. We estimate the effects of these variables, and compare the results with those from previous studies performed for other economies. Concerning the effects of business cycle, we find that the business cycle is an important factor in determining the number of bank relationships. The number of bank relationships varies over the business cycle, and we notice a counter-cyclical behavior, which means the number decreases during economic expansions and increases during contractions. This result can be interpreted as a result of firms' diversification of borrowings into multiple banks in order to reduce the liquidity risk during the recession. In the subsets, however, the number of bank relationships for large firms is stable regardless of the business cycle. Unlisted firms, non-chaebol, and low credit quality firms which have relatively limited access to alternative sources of financing show counter-cyclical behavior. Finally, such phenomena is not observed in the non-competitive credit market, while they show a counter-cyclical behavior in the competitive credit market.

In accordance with the changing of society, remarkable increase in knowledge and information, the competencies to choose and use proper information in various domains are considered as an important skill. As one of the methods in developing these competencies, it is emphasized that a problem-based learning can make student understand and use knowledge by solving the contextualized problem. However, it is skeptical of learner's development of competencies to use knowledge by solving well-defined given problem. Therefore it is required that students be allowed to develop the competency to find problem through experiences to determine and evaluate the purpose of the problem and method. The purpose of this study is to understand how undergraduate students use science or technology in finding a problem. In this line, this study articulated four cases conducted by participants who engaged in convergence teaching-learning program. And this study investigated the participants' process of problem-finding, method and reason to apply science or technology. The results were drawn by analyzing interviews and written data, including their proposal, a poster, and final reports. Participants changed the form of problem from initial ill-structured one into a concrete one, where the participant could derive a detailed solution. Science or technology applied as the detailed example to convert problem into a concrete form, or as the analyzing tool or theoretical background of problem to make a link with other domain. Their reason of applying science or technology could be summarized in 'personal interest based on prior experience' and 'alternatives to resolve a dissatisfaction.' Based on the result, this study suggests holistic approach that is included in both intuitive thinking and logical thinking and metacognitive regulation to stimulate problem-finding in problem-based learning program.

The purpose of this study was to investigate the existing theories related to overtraining syndrome and to examine the mechanism of overtraining syndrome from the viewpoint of brain science by examining domestic and foreign literature related to the relationship between overtraining syndrome and brain neurotransmitter. The aim of this paper is to provide basic data that can improve the understanding of the mechanism of overtraining syndrome and the role of neurotransmitters and neuromodulators. The results of this study and a number of hypotheses about the overtraining syndrome were proposed, each with strengths and weaknesses. Similar symptoms that occur when the concentration of serotonin in the neurotransmitter increases are related to signs and symptoms of overtraining syndrome. However, it has not been validated to date because it can not distinguish the mechanism of the mediator between the central nervous system and the peripheral nerves. This study suggests that the mechanism of overtraining syndrome will provide important basic information to understand the complex causes of overtraining syndrome through the interaction of existing theory and brain neurotransmitter. Although there has been a lack of studies on the mechanism of overtraining syndrome and brain neurotransmitters so far, we hope that this study will provide an opportunity for more and more people to broaden their understanding of overtraining syndromes.
