  • The purpose of this study is to construct a GIS / DB by grasping a small but ecologically valuable village wetland distribution, and to propose conservation management and wise use plan. The study area is Seocheon-gun, a typical farming village. Firstly, based on the digital topographical map (1:5,000), the Arc-GIS tool was used to identify the provisional(draft) village wetlands. In addition, for the management of village wetlands, wetlands with an area of more or less than $625m^2$ each were derived and according to ecological regions study area was classified into urban areas, inland areas and coastal areas. And finally, according to the wetland identifying indicators, the village wetlands were identified as the final village wetlands through indoor and field trips. The results of the study show that there are 570 village wetlands in Seocheon - gun province, which are 74 in urban areas, 220 in inland areas, and 276 in coastal areas. The case study for village wetland identification was conducted in one out of two urban areas (Seocheon - eup), two of four coastal areas (Biin - myeon and Seo - myeon), and three of seven inland areas (Masan - myeon, Hansan - myeon, and Sicho - myeon). The distribution of village wetlands was found mainly to be a village wetland with an area of less than $625m^2$. In addition, compared with inland areas, the discrimination rate of village wetlands in coastal areas and urban areas was relatively low, indicating that inland areas were still less disturbed, and land use in urban areas and coastal areas is changing rapidly. Especially, land with less awareness such as village wetlands is relatively easily damaged, and management strategy is urgent.

  • This paper examines how democracy is being taught in secondary school level of Indonesian civic education. For this purpose, this study analyses the textbook contents concerning democracy. First, this study sets the freedom, the right, the unity and the stability as key words and analyzes the characteristic of describing democracy by looking at how each keyword is explained in the textbook. The result of analysis shows that democracy of Indonesia can be described as "Pancasila democracy" and textbooks have tendency to relatively emphasize 'the unity', and 'the stability' by differentiating themselves from "liberal democracy" and "liberalism." The freedom in textbook can be interpreted in the context of organic-statism that state and interests of state have the ascendancy over individuals. This viewpoint is based on the historical contexts of Indonesia. However, when textbook describes about Indonesian democracy and its values, they deal with contents of democratic principles, "the freedom of opposition", "the negative freedom", and natural rights. And the study interprets the existence of the two contrasting concepts - relative emphasis on the unity of state and the statement about the importance of individual rights and the freedom - in the textbook as a logical tension in transitional process of traditional organic-statism. Second, the study examines educational contents in accordance with the method of description in textbook. It has been found that there are logical tension and fallacy in describing the principle of fundamental concepts and applicate that concepts into Indonesia case. Also, when describing Marsinah and Munir case, there are some parts distorted and overlooked the facts. On the other hand, the gaps between the explanation in textbook and reality can be pointed out. This study which examined textbook and contents of the rights of the individual is an introductory study on textbook, education and democracy for development of Indonesia and their education.

  • In order to secure sustainable financial resources and to attract more key supporters, today's art museums are trying to further develop individual sponsorship. The purpose of this study is to explore the direction of membership programs by considering membership as the first step for the development of individual supporters for art museums. Although it is not easy to generate substantial profits within a short period through membership, art museums can secure supporters who empathize with and participate in their mission and activities by developing individual supporters through membership. The new trends of support, which has emerged as a stream of "new philanthropy" since the 1990s, indicate that the needs and motivations of individual supporters are changing. This has great implications for the direction of the development and operation of membership programs at art museums. This study investigated the role, method, and direction of the development of individual supporters through membership by conducting a theoretical review and a case study on the membership programs and individual sponsors of art museums. In addition, the study analyzed the cases of the Cleveland Museum of Art, the Art Institute of Chicago, and the Museum of Modern Art in the United States, which have continuously attempted new approaches and improved membership programs based on a long history of membership operation and individual support, by centering on the new attributes of philanthropy, including participation and involvement, accountability, and transparency. Based on the results, implications and suggestions for Korean art museums were derived. Amid the lack of art museums' membership programs and academic research, this study has significance in exploring the direction and prerequisites for membership for the development of individual supporters.

  • Mathematics is a way of thinking. To do mathematics means to think mathematically. In other words, mathematics education and mathematics literacy are related. In elementary and secondary school mathematics education in many countries, teaching of mathematics using textbooks is conducted mostly in their native language. So mathematics education takes place while reading, writing, listening, and speaking mathematics. Analysis of mathematics textbooks for the lower grades of undergraduate mathematics shows that most advanced countries in mathematics use excellent undergraduate mathematics textbooks written in their native language. However, the ratio of using imported textbooks from foreign countries is particularly high in the case of textbooks for mathematics majors at Korean universities. In this article, the effect of language used in university mathematics education is analized. In particular, the importance of high-quality leading-edge university mathematics textbooks in native language is introduced by analyzing the case of Bourbaki in France and 'War of language' at the Israel Institute of Technology. The innovation of French university mathematics education in the 20th century began with Bourbaki's 'Fundamentals of Mathematics', a French textbook written in his native language. Israel's Technion and the Hebrew University of Jerusalem continue to teach all subjects in their mother tongue. This has led to produce many Nobel Prize and Fields medal winners in these two countries. This study shows that textbooks and languages used in university mathematics education has affected mathematical literacy.

  • This study intends to suggest the cooperative, win-win collaboration, as methods for settling disputes with the existing self-employed people over back-street business areas and disputes and conflicts between a franchiser and franchisees. In addition, it intends to analyze the Dunkin' Donuts purchasing cooperative in the US, where the franchising industry has been well developed; and to find the implications of cooperation strategies between Dunkin' Donuts and its franchisees that may be helpful for the South Korea's franchising industry. This study tries to discover a new model of the Korean-style franchise cooperative out of the basic principles and practice guidelines of cooperatives ranging from an early American franchise cooperative in 1955 to ARCOP, KFC, and Dunkin' Doughnuts in the late 1970s. Further, it looks into successful programs of a purchasing cooperative at Dunkin' Donuts such as TDP (Total Distribution Program), SFP (Shortening Futures Program) and DCP (Distribution Commitment Program). The case of the US Dunkin' Donuts, which operates the purchasing cooperative, suggests the following for the improvement of franchisees' profitability. First, relations of cooperation rather than of power are necessary between a franchiser and franchisees. Second, mutual solidarity of franchisees is necessary. Third, problems proper to the Korean franchise system should be improved. Fourth, an entrepreneurial spirit of going together rather than going fast is required. Fifth, complete satisfaction management is required. Considering different system environments between the two countries such as quantitative expansion within a short franchising history of 30 years or so and franchise profit models, there is a limit to generalizing down to a successful model of the win-win partnership cooperative. It is hoped that the sustainable management of the domestic franchising industry will be promoted in the future through the in-depth analysis of successful cooperatives.

  • The burden of medical expenses and the loss of social capital due to chronic diseases are becoming problems worldwide, and comprehensive and inclusive measures across various fields are required to prevent and manage their impacts. Social prescriptions have been shown to be effective in resolving the fundamental causes of health problems in patients with chronic diseases and in supporting existing treatments. In particular, green prescriptions that utilize the healing effects of nature and green spaces based on social prescriptions are being introduced in many countries overseas. Green prescription is the practice of a healthcare provider recommending activities in green spaces or experiences in the natural environment to patients for the prevention and management of chronic diseases. This study analyzed cases focusing on the policy system, the cases of the United Kingdom and the United States, which have introduced and operated green prescriptions under a national system. For this purpose, this study compared the background of green prescription introduction, related policies, and operation methods. Based on this, four implications were proposed to establish an effective plan for introducing green prescriptions in Korea. First, prior to establishing a policy for green prescriptions, interest in and research on green prescriptions are essential. Second, an implementation plan that fits the national health care system should be established, and policies should support the plan. Third, the introduction of green prescriptions from a long-term and gradual perspective is required. Fourth, comprehensive cooperation is required for the introduction and implementation of the green prescription system. This study can be used as basic data for discussion before introducing green prescriptions in Korea in the future.

  • Innovation means the creation of new value by changing existing things. Dyson's Cyclone vacuum cleaner, a representative innovative product, eliminated the dust filter that had existed in vacuum cleaners for over 100 years. Instead of directly improving the dust filter that reduces suction power, this product was invented by asking the essential question, 'How do we separate dust in the air?' Creative innovation happens when the essence of the problem is properly understood. TRIZ(Theory of Inventive Problem Solving) analyzed numerous invention patents and discovered that innovative results in problem solving appear depending on the existence of contradictions in the problem and how to creatively overcome the contradictions. Based on this, it was systematized into a methodology along with other powerful principles of problem solving. Therefore, TRIZ is a powerful tool for creative and innovative problem solving. However, for creative innovation, it is not easy to properly identify the contradictions in the problem and apply them to solve the problem. However, for creative innovation, it is not easy to properly identify the contradictions in the problem and apply them to solve the problem. In addition, depending on which contradiction is selected, not only the direction of problem solving but also the final solution varies, but researches on this are very lacking. To overcome these difficulties, this study first introduced the concepts of existence contradiction and state contradiction, presented a new problem-solving process, and verified its validity by applying it to toothbrush patent cases. Although there are limitations in applying it to various cases, we hope that the new concept of contradiction presented for the first time in this study and the problem-solving process through it will contribute to producing innovative results.
