This study was conducted to identify consumer's beef and pork demand system using consumer panel data of RDA. According to LA/AIDS analysis of beef and pork by region of origin, all parts of meat was significant in expenditure weight and elasticity. In addition, all of the items analyzed as having significant price elasticity were negative and classified according to the law of general demand. Alternative relationships were found in domestic beef tenderloin, strip loin and brisket, domestic beef shoulder and domestic pork hind foot, imported and other beef tenderloin, strip loin and imported and other pork ribs, domestic beef topround and imported and other pork forefoot. The purpose of this study is to provide information necessary for more rational production and consumption activities by grasping the substitution relationship between meat parts by estimating the demand system of each region of beef and pork origin. In addition, the identification of consumer demand by region and country of origin can also influence the systematic goal of raising livestock.

The purpose of this study is to analyze the complementarities among expected progeny difference(EPD) traits of Hanwoo steers. Data on 38,819 Hanwoo steers slaughtered from 2015 to 2016 were used. Four EPD traits are carcass weight(G1), eye-muscle area(G2), back-fat thickness(G3), and marbling score(G4). The results show that G1 and G3 always act as complements, except when G2 and G4 are used at the same time. when G2 is used, G1 and G4 are complementary. Additionally, G2 and G3 are complementary when G2 is used. G1 and G4 are complementary when G2 or G4 is used. G2 and G4 are complementary when G2 is used. However, G1 and G2 are subadditivity, when G3 and G4 are not used. The results also indicate that the revenues were higher in spring and lower in autumn and winter than in the summer. Furthermore, the carcass weight and rearing period were increased, the revenues were increasing. The results of this study may contribute to the government's policy for Hanwoo breeding and provide useful information on Hanwoo rearing management.

As the number of companion animals increases, the pet food industry is growing rapidly in Korea. The objective of this study is to identify consumers' preferences for companion animal feed attributes by using choice experiments. It was analyzed that the feed consumers are more satisfied with the following factors: lower price, organic materials, functional food materials, domestically produced feed, non-allergic and meat-based ingredients. According to the results of measuring consumers' WTP for feed attributes, feed using organic material is the highest at KRW 7,438. Allergen-free feed is KRW 6,058, and domestic feed is KRW 2,459. Functional feeds are lower than other attributes of KRW 1,491, and KRW 3,581 and KRW 5,039 are more likely to be paid than seafood and vegetables when the main ingredient of the raw material was composed of meat. As a result of the estimation of latent class models, Group 1 prefers the lower feed price and the mixed ingredient. On the other hand, groups 2 and 3, which are relatively low in age, prefer feeds with various attributes, and Group 2, in particular, has the characteristic of purchasing high quality feeds even at higher prices.

The effect of the enactment of Improper Solicitation and Graft Act on Hanwoo industry was analyzed by using the VAR model. We analyzed the out of sample prices that were not affected by the Act, and compared them with the actual prices. Drops were found for both farmgate and wholesale prices, which can negatively affect the management performances of farms. The retail prices, however, were not directly correlated with the farmgate and wholesale prices due to the elevated marketing costs, which in turn can shrink the Hanwoo market drastically. Overall the enactment of the Act resulted in a great reduction of the Hanwoo demand. However, the data studied was collected over only 1 year, and therefore further observation is necessary to provide more authoritative conclusion on the effect of the Improper Solicitation and Graft Act on the Hanwoo market.

The government introduced the Non-pesticide Processed Food Certification System with three alternatives to activate eco-friendly processed food market. This study investigates consumers' and processed food companies' perceptions on the three alternatives. And we analyze the effect of Non-pesticide Processed Food Certification System on the non-pesticide and organic processed markets using partial equilibrium analysis. As a result of the analysis, the first option was most suitable considering the opinions and benefits of stakeholders; The first option is to certify and logos only if the raw material content of non-chemical agricultural products is over 95%, and less than 95% should apply the limited labeling. The results show that the adoption of first option would result in an average increase of 49.9% in consumer WTP and an 26.4% in production cost, increasing sales of existing non-pesticide processed food by 20.0%. We suggest the following measures to settle the Non-pesticide Processed Foods Certification System: Improvement of consumer awareness about non-pesticide raw materials and promotion, patriotism marketing, promotion for negative recognition of vendor's certification system, the establishment of a stable agricultural supply management system for non-pesticide raw materials etc.

We analyze the relationship between Internet activity and egg purchases following the incident of egg pesticide detection in 2017. For the purpose, we collected the internet search index provided by NAVER Data Lab and consumers' sentiment indices (negative, positive, and neutral) generated from hundred thousands of texts extracted from cafes and blogs of NAVER and Daum, and consumers daily egg purchases which are obtained from the Agri-food Consumers Panel Survey conducted by the Korea Rural Development Administration. The main results are as follows. First, the Internet search index and negative sentiment index of 1 days ago had significant effects on the purchasing amount of eggs, while their purchase amounts did not affect Internet activities. Second, the 1% increase in the internet search index and the relative negative sentiment index decreases the egg purchase by 0.053% and 0.17%, respectively, while the relative positive sentiment index does not affect the egg purchase. These findings show that social media usage data such as Internet search volume, sentiment index can be more efficient and quicker measures (or tools) than existing alternatives to identify food consumption issues or to predict short-time trends of food products. Therefore, all data related to internet and social media usage could serve as a tool to provide useful information in terms of making marketing strategy of food producers and food processing companies, and establishing the crisis management policy of agricultural policy authorities.

This study analyzes the option value of flexible cropping system of smart farming with information and communication technology (ICT), which have been adopted for alternatives to traditional farming. In the study we consider two crops, paprika and tomato, that have very similar facilities in smart farming, thus no additional cost is required for switching crops. A simulation based real options approach is adopted to get the option value of flexible cropping system under uncertain market condition. Market prices of two crops are assumed as stochastic variables and proven to follow Mean Reverting Process. Results shows that the probabilities of cultivating paprika and tomato are fifty one percentage and forty nine percentage, respectively, when flexible decision making for crop selection is reflected. Farmers with smart farming change crops about 7.8 times for thirty years of business period. The option value of flexible cropping system of smart farming is 118,588 thousand won for thirty years, which is the difference between the flexible system and the system with paprika only. This implies that profit- ability analysis with option value may have positive impact on farmers' adoption of smart farming.

This study measures the fertilizer value of livestock manure and analyzes the impact of livestock manure management policy on the utilization of livestock manure as a resource. Fertilizer value of livestock manure was estimated using the amount of fertilizer components contained in livestock manure and the price of chemical fertilizer. The effect of the policy on the utilization of livestock manure was estimated using the seemingly unrelated regression technique and the system of linear equations representing the relations between livestock manure utilization and the government financial support(subsidy and loan). The result indicated that the average fertilizer value of livestock manure is about KRW 405 billion per year over the last five years (2013-2017). The increase in the financial support by KRW 100 million increased the amount of livestock manure utilized as a resource by 5,884 tons.

The positive effects of green care on human health are well acknowledged. As one of the green care types, care farming is novel practice, which combines agricultural production and providing care to people with different types of disabilities. In South Korea, care farming is relatively new. Initiatives have been taken by innovative farmers and social workers. This study provides a comprehensive understanding of the current status of care farming in South Korea and suggestions for further development of the field. The characteristics of care farming, and the experiences and perceived challenges of care farmers in South Korea were studied through 10 semistructured interviews. The majority of South Korean care farm users are people with intellectual disabilities. Financial problems are one of the crucial challenges threatening the sustenance of care farming. Care farming in South Korea lacks a clear orientation and description. Respondents indicated that proper regulations and agreements on the focus of care farming would significantly contribute to the development of care farming. The successful development of horticultural therapy in South Korea can serve as an inspiration.

The objectives of this study were to review the policies of environmentfriendly agriculture to establish a virtuous cycle in production, distribution, and consumption based on consumer trust and to suggest implications for what is needed to foster environment-friendly agriculture in the future along with the diagnosis of related policies and projects. To achieve these objectives, this study examined relative weights and priorities of the evaluation factors for environment-friendly agriculture policies. Moreover, this study conducted an importance-performance analysis (IPA) on environmentfriendly agricultural policies and projects targeting farms. The results of AHP analysis on the relative importance and priority of the key criteria (1st hierarchy) revealed that the magnitude of importance was in the order of distribution system and public plate (0.391), human resource and governance (0.233), promoting environment-friendly consumption (0.218), and enhancement of production structure (0.157). These results can be interpreted that policy measures are needed for securing a stable market and increasing consumption in the public sector. It is necessary to improve the constitution of local agriculture by securing manpower than can lead to agriculture and establishing governance among subjects. The results of the IPA showed that the areas that should be maintained and strengthened are policies and projects for stable production, stable market, and consumption promotion. Secondly, it was also found that the areas that should be mainly invested are policies and projects for infrastructures such as manpower, technology, and processing. Thirdly, the areas that should be improved gradually are mainly policies and projects to diversify governance and sales channels. Lastly, areas to be maintained are policies and projects for traceability, monitoring, and local foods. Environment-friendly agriculture policies and projects should be concretely promoted in the long term by clarifying the goals of policies such as providing safe food to consumers, securing competitiveness in rural areas, and preserving ecological environment.
