The purpose of this study is to evaluate the economic value of an urban landscape. The site of this study was Independence Park in Seoul. Before measuring economic valuation, an amount of view analysis was performed to learn the visual characteristics of the landscape. As a result, the green space ratio of the park is approximately 64%. This study estimates the intrinsic value of an urban landscape that might be included in housing prices using a hedonic price model. The hedonic price model is a statistical analysis that is often used to estimate intrinsic values of certain attributes of a product. The Box-Cox model was adopted as an analysis tool while the housing price for $3.3m^2$ was used as a dependent variable and housing and landscape features as independent variables. Results show that the value of the landscape of the Independence Park is approximately 2.2% of the housing market price. The Landscape variables of the park is the second most significant of the 8 variables. This shows that residents perceived the view of the urban landscape as one of the most significant factors in their living environment. The study also indicates that urban landscapes play important roles in improving quality of life and in influencing housing prices. The implication of the study can be said to be the potential of the urban landscape as a significant urban infrastructure. These results can be used to help make policy decisions to preserve and/or develop urban landscapes.

This study aims to identify negotiation alternatives related to Post-2012 reducing emissions from deforestation (RED) and enhancement of forest carbon stock (EFCS) activities. It also aims to recommend a negotiation strategy considering environmental integrity and national interest on the basis of estimating reduction potentials of each alternative on the assumption that tradable carbon credits play an important role as positive incentives. In order to estimate greenhouse gas (GHG) reduction potentials and income potential from RED and EFCS activities, 99 countries were selected by the Global Forest Resources Assessment of the Food and Agriculture Organization of the United Nations. A 'baseline and credit' method was applied to estimate RED activities. Gross-net and net-net methods were applied for EFCS activities. According to the results, Brazil, Indonesia, and the Democratic Republic of Congo have more potential to get positive incentives through RED, while China, Chile, and the Republic of Korea have more potential to get positive incentives through EFCS. This study suggests including both RED and EFCS activities in the boundary of policy approaches and endowment of positive incentives to consider GHG reduction potentials in the global scale and equity among developing countries. Making a discount rate application of forest management activities can be also recommended to factor out the effects of human-induced activities by EFCS activities.

This study is aimed to investigate microbiological contamination of Angelica gigas Nakai. A total of 111 samples including root, soil, and irrigation water were collected from farms and market to detect aerobic bacteria, Bacillus cereus, coliform, Escherichia coli, Listeria monocytogenes,. Salmonella spp., and Staphylococcus aureus. The contaminations of aerobic bacteria, coliform, and Bacillus cereus in the root during cultivation were found 6.71 log CFU $g^{-1}$, 4.13 log CFU $g^{-1}$, and 3.54 log CFU $g^{-1}$, respectively. The contamination of coliform and B. cereus were detected in all steps from harvesting to processing, with the highest count recorded from the cutting step. In marketing, the contaminations of aerobic bacterial, coliform, and B. cereus were 5.5~6.0 log CFU $g^{-1}$, 2.4~2.6 log CFU $g^{-1}$, and 3.5~4.0 log CFU $g^{-1}$, respectively. Listeria monocytogenes, Salmonella spp, and Staphylococcus aureus were not detected in any of samples. This result indicated that hygienic soil management and post harvest management should be performed to reduce the contamination of hazard microorganisms and to produce safe agro-products.

Rice yield of South Korea in 2015 was the highest in last 30 years. The future direction of food policy in South Korea can be determined depending on whether the historically highest yield in 2015 can be continued or just one-off event. Therefore, it is necessary to understand whether such a high yield as 2015 can be reoccurred and how often it can occur. This study used the yield monitoring data from National Institute of Crop Science, Rural Development Administration and the meteorological data provided by Korea Meteorological Administration to identify the weather conditions, which could cause high yield, and how often these conditions occurred in the past. Our results showed that significantly high yield in 2015 could occur only when the mean sunshine hours of July and the mean sunshine hours from the end of August to early September are 5.1 hours and 6 hours, respectively. The probability of satisfying these weather conditions was 8/35 (23%) over the past 35 years. And the probability of successive high yield for two years was 1/35 (2.9%). The probability of recurrence of high yield within the next 5 years or 10 years after high yield was 4/35 (11.4%).

Purpose - This is a comparative study of the market development and characteristics of Ulsan in South Korea, Fukuoka in Japan, and Yanji in China, which are major East Sea Rim cities with adjacent areas of similar natural characteristics of the sea and the country. Particularly, it considers these aspects while focusing on the evolution of networks that appear in the distribution system and at the same time examining the institutions of market activation and regulations that are handled by the central and the local government and the changing logistics due to the development of transportation and the concern of food safety, using a meso-analysis approach. Research design, data, and methodology - The study used a historical and comparative approach with a focus on case studies. It made use of various materials such as local newspaper articles, reports, literature, interviews with experts, discussions with local merchants, discussions with customers, and so forth. Results - In the case of Fukuoka, from the 1960s, due to the entry of supermarkets, supermarkets expanded and they have now come to a dominant market position in the current market. They offer a convenient and comfortable environment while providing a large mall offering a variety of educational and cultural activities for customers to meet the customers' needs, such as the preferences of Korean tourists, who appear to prefer Japanese foods. The Fukuoka City Central Wholesale Market has been exporting fruits and vegetables as well as seafood products to Korea, China, and so forth. In the case of Ulsan, as in the early 2000s, due to the expansion of supermarkets, the traditional markets have been shrinking and further, the modernization of traditional markets was conducted under the auspices of the Small Business Administration. In addition to the large discount malls, the expansion of SSM is expected to further drive the small trader bay. Shopping malls, department stores, and traditional markets contend with each other in Yanji, China, but a large number of citizens appear to prefer traditional markets and imported milk in the supermarket after the melamine scandal in China. Recently, the WanYuan (萬源) wholesale market has been partially completed and made an attempt to become a logistics hub in Northeast Asia. Conclusions - For the development of Korea's retail industry, it is important to offer the government with proposals regarding desired regulation. On the other hand, in order to enable the business of traditional markets, it requires an association for cultural tourism. At present, it would be better to provide a venture fund for the youth rather than infrastructure support. This study emphasizes the importance of institutions and policy to develop networks in the East Sea Rim. Future studies should conduct a survey on customers, managers, and merchants more carefully and systematically to understand the market situation while considering the size of the city and its evolution of markets, as well as policies and institutions.

This study was conducted to investigate the factors related to smoking and smoking differences among adolescents who have experienced smoking using data from the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data used in this study were from 5,347 middle and high school students who had cigarette smoking and electronic cigarette smoking experience among 68,043 respondents to the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data were evaluated by frequency analysis, the ${\chi}^2$ test and logistic regression analysis using weighted composite sample analysis. Overall 20% of the total smoking adolescents were dual users and 85.6% of the users of electronic cigarettes used nicotine. The results from multinomial regressions show that: male students (OR 1.63; 95% CI 1.15-2.31), living in the metropolitan area (OR 1.76; 95% CI 1.32-2.33), an average consumption of fast food of once or twice a day (OR 2.48; 95% CI 1.33-4.64), first started smoking during high school (OR 0.76; 95% CI 0.58-0.98), having experience with passive smoking (OR 1.24; 95% CI 1.07-1.44), experience drinking alcohol (OR 2.03; 95% CI 1.65-2.48) and those with higher weekly allowances were more likely to be at risk than dual users. This study provides basic data regarding the dual use of electronic cigarettes and cigarettes by adolescents. The results presented herein will facilitate development of a smoking cessation program and policy.

BACKGROUND/OBJECTIVES: Sodium intake is positively associated with blood pressure, which may increase the risk for cardiovascular disease (CVD). Therefore, we assessed the disease burden of CVD attributable to sodium intakes above 2,000 mg/day and prospectively investigated the association between dietary/urinary sodium levels and the risk of all-cause and CVD-mortality using the Korea National Health and Nutrition Examination Survey (KNHNES). SUBJECTS/METHODS: A total of 68,578 and 33,113 participants were included for comparative risk assessment (CRA) analysis and mortality analysis, respectively, and mean follow-up time for mortality was 5.4 years. CRA analysis was used to quantify attributable incidences of stroke, ischemic heart disease (IHD), and deaths attributable to sodium intake between 1998 and 2016. Cox proportional hazard regression model was used to determine the association between sodium intake and all-cause and CVD-mortality. RESULTS: Mean dietary sodium intake decreased over time, reaching 3,647 mg/day in 2016. Similarly, the population attributable fractions of stroke and IHD, and the number of CVD-associated deaths attributable to high sodium intake/excretion also decreased. In terms of association with mortality, when participants were grouped into quartiles (Q) by energy-adjusted sodium intake, those in Q2 had a lower risk of all-cause mortality than those in Q1 with lower intakes. The risk of CVD-associated mortality was higher only in females with high sodium intake in Q4 than those in Q1. CONCLUSIONS: This nationwide data indicates that, in line with previous studies of multiple cohorts, both low and high sodium intakes may be associated with an increased risk of mortality; therefore, the optimal sodium intake for Koreans needs to be revised.

The decreased body, liver, kidney, spleen and testis weights of guinea pigs by TCDD (2,3,7,8-tetracholorodibenzo-${\rho}$-dioxin) treatment (TT) were statistically significantly increased after treating red ginseng saponin fraction (SF) (p>0.01). After treated with SF, the decreased hematocrits values and numbers of RBC and platelet, activity of amylase and lactate dehydrogenase, levels of uric acid, total protein and albumin by TT were increased, and the increased numbers of WBC, levels of triglyceride, total cholesterol (TC), LDL-cholesterol, HDL-cholesterol, creatinine, blood urea nitrogen, calcium and phosphorus, activities of creatinine kinase, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were decreased after treated with SF. And they all had a statistical significance (p>0.01) except for RBC, WBC, platelet, blood glucose, TC, calcium and albumin. From these results, we knew that SF mollified the acute toxicity induced by TCDD in guinea pigs.

Objectives: As a newcomer to the medical tourism industry, Korea needs to differentiate itself from the leading competing countries to vitalize its early-stage medical tourism industry. This study aims to introduce a strategic plan to vitalize the Korean integrated medical tourism so that Korea can differentiate itself from competing countries and create high added value. Methods: The concept and actual conditions of medical tourism and Oriental medical tourism were examined. A plan to differentiate Korea from the competing countries in the medical tourism industry was studied to create high added-value through strategic vitalization of its medical tourism industry. Results: Korean integrated medical tourism must be developed differently from those of other South-East Asian countries in order to strategically promote the cash-cow medical tourism industry. In order to develop such medical tourism, Korean medical practice, which integrates Western and Oriental medicine, is to be developed through mutual understanding and fusion of other disciplines among medical doctors and Oriental medical doctors who are working in local healthcare for health promotion of local residents and disease prevention and control. This will play a key role in developing a unique medical tourism product of Korea by means of strategic alliances as an integrated medicine. Manpower specialized for integrated medicine is to be specially supplied for Oriental medicine-related business lines at city, county and borough levels, among local governments, that are enthusiastically carrying forward Oriental medical tourism with an interest to promoting more active and strategic business development and raise the effectiveness and efficiency of public health centers handling related medical tourism. Manpower specialized for Korean integrated medical tourism is to be specially supplied for the Ministry of Culture, Health and Tourism, a policy control tower to develop and vitalize high value-added fusion (theme) tourism products such as the Korean integrated medical tourism, in order to discover, promote and support Korean integrated medical tourism's differences from existing medical tourism. Conclusions: The differentiated integrated medical tourism that only Korea can offer in a variety of forms, in order to create a key area of high value-added medical tourism, should be strategically vitalized through a liaison between integrated medicine and tourism and the realization of patient-centered health care services with medical technology developed based on mutual understanding of Western and Oriental medicine.

The demand for livestock and poultry products including beef, pork, chicken, egg and milk whose income elasticities are relatively higher than other staple foods, has been increased significantly during the past two decades in response to the remarkable increase in per capita GNP. This trend will be continued during the fifth and the sixth five year economic development plan period beginning with 1982. The annual GNP growth rate will be 7.5% on the average during the next 10 years. It is greatly needed to estimate the demand for beef, pork, chicken egg and milk and to study the feasibilities of domestic production of livestock products for the formulation of adequate policies in order to equate the consumption and the production during the 1980s. So this study reviewed the possible changes in the food consumption patterns during the 1980s, estimated the demand for beef, pork, chicken, egg and milk by using empirical demand functions and finally made suggestions for the formulation of long term price stabilization policies for each livestock, poultry and dairy products through the equilibrium of the quantity of demand for and supply of the products. There are many factors affecting the demand for meats, but this study considered own price, prices of supplements and substitutes and per capita income as the independent variables in the demand equations. It was found that it's own price and income were most significantly affecting factors among others and the degree of substitution effects were remarkably different among the products. According to the meat demand derived in this study, per capita consumption of beef, pork and chicken in the base year 1982 was 11.2kg for total meat, 2.5kg beef, 6.0kg pork and 2.5kg chicken, 106 pieces egg, 15.1kg milk respectively, while those in 1991 were 19.3kg for total meat, 4.8kg beef, 9.6kg pork, 4.9kg chicken, 133pieces egg and 44.1kg milk. It is also predicted through this study that, when the level of production costs be maintained, the domestic production of pork and chicken will meet the demand for them during the fifth and sixth five year economic plan period. However, there will be chronic shortage of beef supply during the coming years. The annual import requirement will be 30,000tons to 40,000tons during the period. In order to stabilize the domestic livestock and poultry and dairy products market, the government should introduce measures to curb the increase in beef consumption by encouraging the consumption of pork and chicken. For this, the livestock production policy measures should be concentrated on : 1) the improvement of infrastructures of beef production by introducing advanced feeding and management technology, subsidies for the establishment of facilities and price support programs for farmers : 2) the development of dairy beef : 3) the reinforcement of the forecast systems for pork and chicken production and consumption.
