The structure of the Hanwoo (Korean Native Cattle) Industry remains very weak and vulnerable to the WTO/IMF system. Considering that the majority of cattle farmers are small sized, and that marketing systems are outdated and inefficient, rapid expansion of lower priced beef imports by WTO system and rapid increasing of production costs by IMF system would lead to the deprivation of a regular source of farm income and threaten the stability of rural life. Accordingly, the Hanwoo industry should be expanded in accordance with progress in the implementation of (1) programs for the structural adjustment and (2) measures to compensate for the loss. Efforts for lowering major production factor costs needs to continue, In order to increase the supply of calves at low cost, the programs of collective cow-calf farms should be expanded, thereby reducing the cost of calf purchase, which constitutes the largest share of Hanwoo production cost. Also, feedlot operations should be encouraged for small herd farms in order to achieve a substantial saving in beef production costs by integrated operations from calf production to cattle fattening. A substantial saving would also be made by collective purchase and distribution of various inputs through the cooperatives' channels. Extension services should be strengthened for cattle farm management, cattle care and feeding, prevention of cattle disease, etc. In order to minimize cash outlays for commercial mixed feeds, utilization of far by-products as feeds should be enhanced and production of forage crops productive of resources, such as land and rural labor, during the farm o(f-season, needs to be encouraged. Also, technological development for enhancing the nutritional value of farm by-products should be encouraged. Measures for successful segregation of the Hanwoo beef market should be implemented, thereby enhancing incentive for quality beef producers and protecting consumers willing to pay higher price for quality beef. For development of the Hanwoo industry, a considerable time frame would be required in order for (1) small livestock farmers to make a successful adjustment by staying in the enterprise and achieving increased price efficiency (2) livestock farmers to acquire know-how for producing quality Hanwoo beef, (3) the ongoing Government policy of enhancing price-quality competitiveness, and for improving the quality Hanwoo beef marketing to take root. (4) consumers to increase their ability to distinguish meat quality, and others.

Each cloud service has numerous owners and tenants, so it is necessary to construct a privacy preserving identity management and access control mechanism for cloud computing. On one hand, cloud service providers (CSP) depend on tenant's identity information to enforce appropriate access control so that cloud resources are only accessed by the authorized tenants who are willing to pay. On the other hand, tenants wish to protect their personalized service access patterns, identity privacy information and accessing newfangled cloud services by on-demand ways within the scope of their permissions. There are many identity authentication and access control schemes to address these challenges to some degree, however, there are still some limitations. In this paper, we propose a new comprehensive approach, called Privacy pReserving Identity and Access Management scheme, referred to as PRIAM, which is able to satisfy all the desirable security requirements in cloud computing. The main contributions of the proposed PRIAM scheme are threefold. First, it leverages blind signature and hash chain to protect tenant's identity privacy and implement secure mutual authentication. Second, it employs the service-level agreements to provide flexible and on-demand access control for both tenants and cloud services. Third, it makes use of the BAN logic to formally verify the correctness of the proposed protocols. As a result, our proposed PRIAM scheme is suitable to cloud computing thanks to its simplicity, correctness, low overhead, and efficiency.
This study aimed to aimed to obtain some basis data for the housing consultation and information about housing through survey of needs for the housing consultation. Respondents were housewives from 395 households living in Seoul area. Questionnaire was used for survey and the collected data were classified by two items such as types of residence and age of housewives. The survey was performed during two weeks in September 1997 and analyzed by frequency mean and percentage using SAS program The finding are as follows; (1) According to the actual conditions of housing consultation the main source of information related to housing was a newspaper Those who had experience detached house had much more opportunities than those of multi-family house. The most frequent agency for housing consultation was a realty dealer showing 65.8%. However the percentage of visiting permanent housing exhibition centers was high among the people aged 20 to 30, noted 20.4%. (2) Level of understanding housing consultation showed 3.45 points among 5. This result indicated that the service system of housing consultation were required. Architects and interior designers were most preferred as specialists whom the respondents wanted to consult with . As to the contents of consultation the most required item was changing of interior space(22.6%). In case the housing information leaflet is sold the respondents were willing to pay 523 won for each of it. (3) Among leaflets related to various information leaflets about housing purchase were most preferred(21.0%) According to the result of the survey the need for the information about housing purchase indicated higher preference than about housing management. The fact could be thought that consumers' consciousness of housing should be changed. Therefore it is desirable to lead consumers to lengthen the expected life span of their house and value happiness of the house by providing them with consulting systems about housing management throug housing consultation materials and development of its programs.

This study is a basic research to apply ESD linked to SDGs to pre-service teachers majoring in earth science education. The purpose of this study is to evaluate carbon literacy by analyzing the awareness, attitude and knowledge, subjective norms, and behavioral control of the carbon footprint internalized by pre-service teachers. Pre-service teachers recognize the carbon footprint as their responsibility, but are not willing to pay the cost and accept inconveniences of the actions to reduce carbon footprint. They also support actions to reduce carbon footprint, but do not demand the actions from others. While they have sufficient knowledge about carbon mitigation actions, their conception of causes and effects of global warming is unstable. Pre-service teachers will go out to school sites and teach millions of students about global warming. It is essential to educate these teachers on the economic cost and social responsibility of reducing their carbon footprints. It is also important to find ways to bridge the gap between their thought and action. It is hoped that this study on pre-service teachers' carbon literacy will lead to realizing ESD.
Objectives: The objective of this study is to analyze factors affecting intention to use a paid health promotion service by using the health belief model. Methods: A self-administered survey was conducted with 276 health check-up participants aged ${\geq}20$ at a local medical center in Korea from November 8 to November 24, 2010. Results: 53.6% of the respondents had intention to use a paid health promotion service, and around 85% of them were willing to pay for 'less than five thousand won per month'. Factors affecting the intention to use paid the service was age, education, income, and health check-up experience. In terms of health belief model constructs, people had greater intention to use a paid the service when they perceived to be sensitive to lifestyle associated diseases and recognized advantages of health promotion services. Conclusions: Approximately half of the respondents had intention to use a paid health promotion service. Reasonable price for the service was less than five thousand Korean won per month. Health promotion service act and services should consider these findings.

The current study attempted to assess the environmental value of Geum-river estuary for rational management decision-making. To investigate the comprehensive properties of the Geum-river estuary, we applied the contingent valuation method based on multi-attribute utility theory. We surveyed a randomly selected sample of 400 and 600 households of the Geum-river estuary-neighboring area (Jeollabuk-do, Chungcheongnam-do), and other nation-wide large districts (except Jeollabuk-do, Chungcheongnam-do, and Jeju-do), respectively, and carried out person-to-person interviews with subjects on their willingness-to-pay for the estuary conservation and management program. Respondents, overall, accepted the contingent market system and were willing to contribute a significant amount, that is 1,497 won for the residents from the Geum-river estuary-neighboring area and 4,343 won for the residents from other nation-wide large districts on average, per household per year. These results implied that there were large difference between the two groups. The aggregate values of the Geum-river estuary for the estuary-neighboring area and other nation-wide large districts amount to 2.13 and 70.15 billion won, respectively, per year. This quantitative value deduced from the current study, could be a useful baseline fact for any decision-making process particularly in the establishment of management policies for the Geum-river estuary.
Government provides financial support to the 74 Home help service centers, 36 Day care service centers, and 18 Short stay service centers for the elderly. The number of service centers that receive financial support from the government is far less to meet the potential demand for the community care services. This paper applies cost-benefit analysis to evaluate the net social benefit of the services provided by the 3 types of the community care service centers sponsored by the government to justify the expansion of the government support. The benefit is calculated as community care services are provided privately in the market without financial support from the government. The potential market price is regarded as the benefit or value provided to the elderly. The price levels that potential users are willing to pay for these services are surveyed in the Census for the Elderly by the KIHASA, 1998. The market prices for the community services are generated by equating limited amount of service supply, as in number of users in one year in 3 types of community care service centers, and potential demand for the services. Market prices are multiplied to the number of users of 3 types of community centers to get the total benefit. Total operating cost of the community care service centers is regarded as cost. According to the cost-benefit analysis, Home-help service centers generated net social benefit of 137 billion Won, Day Care service centers generated 15 billion Won, and Short stay service centers generated 6 billion Won. Significant amount of net social benefit indicates that government should increase level of financial support to these service centers.
The objectives of the study were to. 1) explain the seriousness of environmental problems and the importance of environmental education in rural development , and 2) explore more effective and efficient ways of environmental education for agriculture and rural development in Korea. The world has rapidly changed and concepts such as clientele -centered, efficiency, and globalization are flowing under this change. Agriculture or rural development is not an exception. In order for agriculture as an occupation and rural communities to have competitiveness in efficiency and attractiveness, it is important to develop and execute a well-planned program for agriculture and rural development. Otherwise, farmers and rural inhabitants will continue to leave the agriculture and rural areas. Frequent recent reports of newspapers on nit and water pollution, including nutrients and pesticides have brought attention to the seriousness of environmental problems in Korea. Environmental concerns should consider in planning and executing the rural development program. People want to get contamination-free foods, water and fresh air. They can and are willing to pay their money for high quality food, water and a better living environment, as their incomes have been increasing, Agriculture and rural communities may have competitiveness in these aspects. It is irony that environmental concerns makes the possibility of changes in agriculture and rural development in Korea. Environmental education will have an increasingly important role in agriculture and rural development. Environmental problems relate to the human behavior in various aspects. Many environmental problems are mainly rooted to people's ignorance and spending-habits, and lack of technology related to environment. These human behaviors are the focus that environmental education should teach and change. Environmental education has been carried out through various subjects in school education in Korea, but "Environment" in middle school and "Environmental Science" in high school were separated as a regular subject from 1996. Environmental education still has a lot of room for development from a theoretical frame work. Environmental education should be carried out as action-oriented, student-centered programs. Various teaching materials, programs and proper supporting budget should be developed so that environmental education fulfills its necessary role well in agriculture and rural development. A textbook about the environment alone will not guarantee a high quality environmental education.

Knowledge management becomes the key point for organizations to survive and maintain competitive advantages in the knowledge economy era. E-learning plays a vital role for the organizational learning. How to share the experience of knowledge and the success of the knowledge management has great connection with the organizational culture. This study focuses on the factors of effective E-learning as well as its relation to the organizational culture. A successful e-learning system should not only aim at different statistical variables but emphasize on : course contents, variety of teaching methods and establishes a stable network environment. A stable E-learning platform and speedy bandwidth is a must to achieve the non-barrier communication and built an interactive learning environment. To achieve success in E-learning, it is not necessary to divide the organizational culture to strengthen the course content multiplication and plans the E-learning supervisory work by the sole responsibility unit. It should establish an ample teaching frequency width and platform and also must establish the appropriate study network frequency width and hardware equipment to achieve the best E-learning effect. The interaction in different organizational culture in adapting E-learning, those Ad-hoc and Marketing Culture, are mostly influence by the external environment and have more interactive content. Those in Clan and Hierarchy Culture are affected by traditional conception and lack of interaction. Meanwhile, under the cost consideration, Clan and Ad-hoc Culture on the dynamic side prefer to spend more cost on E-Learning while the stable side, Hierarchy and Marketing culture are willing to pay more expenses on E-Learning.
Objectives : To determine the prevalence, pattern. and out-of-pocket expenditure of complementary and alternative medicine (CAM) utilization in Korean adult population. Methods : We conducted a representative telephone survey of 2,042 persons aged 18 or older. Data about any health problem, details of their use of medical doctors(MDs) offices/hospitals/pharmacies services and CAM during the preceding 12 months were collected with structured questionnaire. Results : The utilization rate of CAM among Korean adults was 29% in one year. A total of 231 kinds of CAM was identified from this survey. Annual out-of-pocket expenditure associated with CAM use in 1998 amounted to ${\xi}{\S}1.88$ billion and was comparable to 40.8% of out-of-pocket expenditure paid for MDs offices/hospitals/pharmacies services. Among those(N=424) who paid for both MDs offices/hospitals/pharmacies services an d CAM, 35.8% paid more for CAM. CAM gave more satisfaction than western medicine to those who had experience of both types of therapy. About half of CAM users were willing to recommend CAM to others. Disclosure rate to physician among CAM users was not high(40.6%). Conclusion : CAM became a popular source of health care in Korea, Korean spent a substantial amount of out-of-pocket money on CAM without any public control. Because CAM use is likely to be increased rapidly through lay referral system, health policy makers and health professionals should pay more attention to CAM for making appropriate utilization of CAM.
