Data mining is an information extraction activity to discover hidden facts contained in databases. Using a combination of machine learning, statistical analysis, modeling techniques and database technology, data mining finds patterns and subtle relationships in data and infers rules that allow the prediction of future results. Typical applications include market segmentation, customer profiling, fraud detection, evaluation of retail promotions, and credit risk analysis. Law enforcement agencies deal with mass data to investigate the crime and its amount is increasing due to the development of processing the data by using computer. Now new challenge to discover knowledge in that data is confronted to us. It can be applied in criminal investigation to find offenders by analysis of complex and relational data structures and free texts using their criminal records or statement texts. This study was aimed to evaluate possibile application of data mining and its limitation in practical criminal investigation. Clustering of the criminal cases will be possible in habitual crimes such as fraud and burglary when using data mining to identify the crime pattern. Neural network modelling, one of tools in data mining, can be applied to differentiating suspect's photograph or handwriting with that of convict or criminal profiling. A case study of in practical insurance fraud showed that data mining was useful in organized crimes such as gang, terrorism and money laundering. But the products of data mining in criminal investigation should be cautious for evaluating because data mining just offer a clue instead of conclusion. The legal regulation is needed to control the abuse of law enforcement agencies and to protect personal privacy or human rights.

To promote the commercialization of high technology based start-up company, it is essential to activate technology trading for the Innovative Small & Medium companies which eager to acquire technology competitiveness through technology trading and facilitate financial system which provide Small & Medium companies with technology commercialization money. This study focus on enhancing credibility of technology valuation solutions through the improvement of the existing technology valuation solutions. The existing technology valuation solutions in practice have deficiency in reasonable valuation because of subjective technology factor's calculation. And the commercialization risk of high technology based start-up companies cannot be fully reflected in the existing valuation solutions. The high risk of technology commercialization acts as a hurdle in the facilitation of providing money for the start-up companies. The improved new model will have more acceptable objectivity and reasonably reflect the commercialization risk of start-up companies. The new model has two distinctive features compared to existing solutions. The new model newly adopts commercialization success factor which reflects the risk of high technology based start-up company. And the new model excludes technology factor which is controversial among interested parties. The exclusion of technology factor will improve the objectivity of technology valuation and the adoption of commercialization success factor will solicit investor and capitalist who concern the high risk of technology based start-up companies. In conclusion, the improved new model is expected to activate technology trading and facilitate the money market through which high technology based start-up companies raise commercialization money.

This study analyzes the current state of entrepreneurship education and start-up foundations by country in order to find ways to improve the domestic entrepreneurial environment and to promote the recognition of desirable entrepreneurship practices. It also investigates the relationship between entrepreneurship, entrepreneurial will, and the level of opportunity-based entrepreneurships, by using data from the 2016 Global Entrepreneurship Trend Report (GETR). First, the results show the urgent need for the expansion of entrepreneurship education in Korea. In the GETR category of 'experience of entrepreneurship education in elementary, middle and high schools', Korea was ranked very low (19th place), among the 20 countries. In the 'college' and 'lifelong entrepreneurship education' categories, it procured a mid-level ranking (15th). While entrepreneurship education for all ages is being promoted globally, entrepreneurship education for middle-aged individuals in Korea is relatively weak. This implies that the expansion of entrepreneurship education to lifelong education and education for employees and retirees is required. Second, the individual's entrepreneurial intention in Korea was 3.8 points, implying a mid-level ranking (15th), and it ranked the lowest in terms of opportunity-based entrepreneurship (20th). In comparison to China (4.55) and the United States (4.01), the entrepreneurial intention of Koreans was found to be low. The level of opportunity-driven entrepreneurship was also found to be very low, compared to China (4.35), Japan (4.04) and the United States (4.59). In general, the proportion of the level in opportunity-driven entrepreneurship, increases from the factor-driven and efficiency-driven, to the innovation-driven type. In Korea, the percentage of entrepreneurial ventures centered around involuntary entrepreneurship and small businesses is high. It is also interpreted that opportunity-based entrepreneurships are low in number because of this high proportion of involuntary start-up and small businesses. Last, the entrepreneurial intention in all types (factor-driven, efficiency-driven, and innovation-driven) was exceptionally high. It has been confirmed that exposure to all entrepreneurship education (elementary, junior high, university, and lifelong education) in innovation-driven countries, greatly increases entrepreneurial intention. In the case of Korea, which is an innovation-driven country, qualitative improvement based on quantitative expansion of entrepreneurship education is expected to be a major driving force for individuals' entrepreneurial intention to obtain a mid-level ranking (15th).

Purpose: The purposes of this study were to investigate eating behavior of university students through social commerce and to analyze factors affecting university students' attitude regarding social commerce. Methods: Questionnaires were distributed to 445 university students in Changwon, Korea from March 28 to April 28, 2013. A total of 339 questionnaires were used for the final analysis, which excluded improperly-completed questionnaires. Results: The major factor considered for eating behavior through social commerce was price (37.2%). Purchasing experiences of foodservice products according to types of foodservice were 64.9% for coffee shop, 59.3% for fast food restaurant, 53.4% for family restaurant, 46.0% for specialty restaurant, 35.7% for pizza restaurant, 35.4% for buffet, and 31.9% for bakery. Factors affecting satisfaction with social commerce for purchasing foodservice products were 'service quality of foodservice company', 'communication of social commerce', and 'discount rate of social commerce'. Factors affecting repurchasing intention of foodservice products through social commerce were 'service quality of foodservice company', 'site design of social commerce', and 'discount rate of social commerce'. Conclusion: In order to increase satisfaction with social commerce, 'service quality of foodservice company', 'communication of social commerce', and 'discount rate of social commerce' should be increased. And, to increase repurchasing intention of social commerce, 'service quality of foodservice company', 'site design of social commerce', and 'discount rate of social commerce' should be increased. In addition, two factors 'service quality of foodservice' and 'discount rate of social commerce' were found to have an effect on satisfaction and repurchasing intention of social commerce. For development of social commerce and foodservice industry, cooperative relationship between social commerce and foodservice industry is needed, and a reasonable price strategy should be established. The university students considered price as a major factor of eating behaviors and did not consider menu and taste as a major factor. From a longer perspective, such an eating behavior would have an effect on university students' dietary life and it would cause nutrition and health problems for university students. Thus, it implied that further studies from the perspectives of nutrition and health regarding eating behavior through social commerce service should be conducted.

This study was performed to develop menu satisfaction index in Business & Industry (B&I) food service and to survey customer's menu satisfaction using the index. The menu satisfaction index included 16 items with Likert 5 point. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8917, which indicated highly reliable. Construct validity was assessed by principal components analysis and then four factors explaining 65.964% of the total variance were found. Among the 15 items of menu satisfaction, the average scores of all items were above 3.0 out of 5. As a result of analysis on menu satisfaction factors, 'propriety of food temperature' (3.52 out of 5) was the highest consideration followed by 'sufficiency of format' (3.46), 'excellence in food' (3.35) and 'well-being orientation' (3.31). It could be said that customer's perception on the menu quality was very positive. Four factors were correlated with overall menu satisfaction positively. Especially, 'excellence in food', and 'well-being orientation' and 'sufficiency of format' affected significantly on overall menu satisfaction. It concluded that customers were satisfied with portion size, temperature, price but their needs for taste and health/nutrition-related service would be increased. The menu satisfaction developed in this study should be applied to other B & I food service operation by type.

This paper attempts to investigate how the cultural phenomena associated with 'Wuyi-Doga(武夷棹歌)' and 'Wuyi-Gugok (武夷九曲)' was introduced to Joseon. The icon and code of 'Gugok' cultural text which was observed in the process of transmitting the culture through repetition and imitation were examined. With regard to research methodology, an 'analysis and discussion framework' was designed based on the literature review, field survey and the seven textuality criteria proposed by Dressier. Then the textuality of 'Wuyi-Gugok' was analyzed in terms of the dependent relation of text, the relationship between the creator and user, repetition, imitation and the spread process. Since ZhouHee(朱熙)'s 'Wuyi-Doga' and 'Wuyi-Gugok' were introduced to Joseon through literature and paintings, they became a part of the cultural Phenomena with unprecedented popularity. As a result, a great number of imitations can be found. In addition, governors would even take care of political affairs in a scenic mountain valley as described in this literature. Regardless of the writer's intentiot 'Gugok' settled in Joseon as new culture in harmony with Taoism and Sung COnfucianism. In other words, Joseon's Gugok-Wonlim(九曲園林) accepted the nature-appreciation aesthetic consciousness in 'Wuyi-Doga' and 'Wuyi-Gugok' on the basis of Taoism and Sung Confucianism. In terms of the text-based dependent relation only, however, the geographical coherence was somewhat loosened while the Gugok Culture that was dependent on Taoism or elegance in life dominated the internal structure of the textuality. Meantime, the internal factors that dominated the textuality of 'Wdyi-Gugok' were interpreted as 1) 'Aesthetics of Bending, Water Whirls', 2) 'Territoriality Expression Carve letters,' 3) 'Cultural Landscape seeing through the Speculation of Meaning,' 4) 'The Pursuit of Oddness and Presentationism' and 5) 'Transcendental Landscape of Taoism and Topos.'

In this study, the landscape of Insa-dong was interpreted from the viewpoint of a social construction of landscape, which regards the dynamic process of landscape change as more important than landscape visibility. This viewpoint also regards landscape as the result of its interaction with certain actors. From a review of previous studies on the same subject, it was found that the physical environment, institutions, and images are essential factors influencing landscape change. Insa-dong, which was Kwanindaing and Daesadong during the Joseon Dynasty, acquired symbolic meaning as a traditional area during the Japanese colonial period because of its many antique shops and Korean-style buildings. In 1970, the establishment of modern galleries in the district added to its image as a haven of the traditional Korean culture. Insa-dong thus eventually came to be referred to as "the street of traditional culture" by the people of Korea. Thanks to global festivals like the Asian Games, the Olympics, and the World Cup, Insa-dong's reputation as a cultural tourist destination has become stronger as these festivals created a need for a place in Korea where the country's traditional culture can be showcased to foreign tourists. After the mid-1990s, the merchants of Insa-dong began to cash in on the district's image as a showcase of traditional Korean culture due to the economic depression that emerged then. The people of Insa-dong and those outside it, however, came to feel that this trend damaged the district's image. Therefore, the people of Insa-dong and the district's local government started a movement to restore the aesthetic value and symbolic meaning of the district's landscape. This effort induced institutional change. Insa-dong used to be a natural haven of traditional Korean culture. Its landscape has recently been reconstructed so that this image could be restored. This process was made possible by the active interaction of diverse people: merchants, users, administrators, and NGOs.

The purpose of this study is to examine the roles of the forest-land registry system in the Forest Law of 1908 and the effects this system had on the colonial forest-land policy used in Korea under the influence of Japanese Imperialism. This was started under the Profit-sharing Forest System which was one of the policies for disposing of the Korean national forests. The purpose of this system was to establish forest-land ownership, a fundamental human right. This system was enforced by the Japanese Colonial Government without regard to the customary and important right of Koreans to use the forests, and without considering the distinction between national and private forests. Koreans understood that this system was a warning sign of a tax being imposing on forest-land owners. Furthermore, Koreans thought the Japanese were using this system to deprive them of their forest-land. The strata of Koreans reporting ownership were very limited and included the intellectual(upper-middle) class, higher officials in counties and townships, relatives and relations of these officials, and survey agents. In particular the actual owners could not submit a report registering their land in this system because the required survey cost more than the value of the forest-land. Within the time period specified by the Japanese Colonial Government, about 520,000 registries were reported involving 2.2 million Jung-bo(.9917 hectare) with most of these coming during the last five months of reporting period. Koreans made a reasonable request to extend the deadline, but it was refused. After the reporting period expired there were no follow-up measures such as verification of the reported registrations nor establishment of boundaries between national and private forests. According to Article 19 in the Forest Law of 1908 about 14 million Jung-bo, which was not registered within the reporting period was nationalized. The colonial forest-land policy used in Korea by the Japanese Colonial Government was as follows : (1) to create a large number of national forests in the early period of their rule, (2) to divide these national forests into indispensible national forests and dispensible national forests, and (3) to transfer ownership of the dispensible national forests to colonial Japanese. To achieve the latter, the occupational government needed a method to insure ownership. They devised a tree-planting scheme in which the national forests classified as disposable were "loaned" and then transferred to these Japanese. The actual Korean owners claimed title to this forest-land and asked for the eviction of the new owners but the Japanese occupation government rejected these suits using the excuse that previous Korean owners did not submit the required registration report within the specified time period. In short the Principle of Forest-land Registry was used as a means to consolidate the forest-lands of Korea and distribute large portions of it to Japanese citizens after seizing it from the rightful Korean owners.
