Animal Welfare is spreading throughout the world, but remains weak in Korean swine farms. Therefore, the aim of this study was to identify the effect of floor type and hanging type environmental enrichment on the behavior of growing pigs under the traditional feeding environment. A total of 45 crossbred pigs (Yorkshire${\times}$Landrace${\times}$Duroc; average weight, $33.35{\pm}5.5kg$) were assigned into three treatments consisting of control, hanging type(T1) and floor type(T2) with three replicates in semi-slurry pen. The hanging enrichment was suspended at shoulder height of the pigs, and the floor enrichment was fixed in the center of the pens. Growth and cortisol were estimated at the end of the experimental period. Behaviour patterns were analyzed on the first and eighth days after starting the experiment. Growth was not differed among control and treatments. However, cortisol was decreased in T2 compared to control(25.28 vs. 46.75 ng/mL; p<0.05). On the first day, movement and aggression were lower in both treatments than in control(p<0.01). On the eighth day, time and frequency of playing action were increased in T2 compared to T1(p<0.01) and both treatment groups showed more active behaviour than control(p<0.01). These results suggested that the enrichment may meet the natural action requirement of pigs. Therefore, our data can be utilized as basic information for welfare with environmental enrichments in farm animals.

This study empirically analyzes changes in production patterns of farmers by agricultural disaster insurance. The aim of this project is to achieve stability of farm management by paying insurance in case of a natural disaster. However, it causes farmers to change production patterns in the direction of increasing production, and leads the crop price to drop. This can be explained by producers' risk reduction through the disaster insurance. The empirical analysis is based on IV approach with using two stage least squares method. The first stage estimates by difference-in-differences methodology indicate that the production of insurable crops increases more about 80,000ton on average than that of non-insurable crops. In addition, to solve the endogeneity problem caused by general supply and demand model, I use the first stage estimates and find that the price index of the crops drops about 2.3% according to the production increase by 10,000ton. The credibility of these results is also attained by various robustness checks. These findings suggest that it is necessary for government to analyze the whole economy which consists of producer and consumer welfare when it determines the policy. Besides, it implies that it is essential to develop a new market to cope with the unintended effect.

The study present the findings divide into brand naming, image, positioning. The farms built trust by consumer relationship with the farm brand. The results of the study provide insights for agricultural marketers who intend to design brand stories that align with their produce. This study is a regional case study of the factor analysis which explain residents' satisfaction of the efficient rural development projects under the Block Grants System in Buyeo. This study attempted to proceed the empirical survey of 353 residents who live in one 'town(eup)' and 13 'village(meon)' in Buyeo-gun and analyzed through SPSSWIN. The results of the satisfaction analysis in the local development projects satisfied with the overall average 3.16 and then empirically verified the important factors of the 'cultural and leisure activities', 'learning environment', 'jobs and working conditions', 'transportation'. The factor analysis of 12 variables united into three factors, the first Factors are 'transportation', 'learning environment', 'social welfare', 'cultural and leisure activities', 'Information and Communication', 'Health and Medical Services'. The second factors are 'crimes and accidents', 'environmental management', 'neighbor relations and social participation', and the third factors united into 'income and consumption activities', 'job creation' which imply the economic variables, and 'residential environment' as the common category.

Equilume light masks had no impact on hastening the resumption of estrous cyclicity in mares maintained in outdoor pastures on the mainland of Korea due to the cold weather conditions. Jeju Island is a major horse-breeding site in Korea and is warmer than the mainland during the winter season. Therefore, the primary objective of this study was to explore the efficiency of the Equilume light mask on the resumption of seasonal estrous cycles in Thoroughbred mares on Jeju Island. A total of 20 nonpregnant mares were randomly divided into the Equilume light mask (n = 9) and stable lighting (n =11) groups. The experiment was performed at seven different horse-breeding farms located on Jeju Island from November 15, 2020, to February 15, 2021. The mares were exposed to the respective lights from 16:00 to 23:00. Follicle size and uterine edema were measured by ultrasound scanning. Body condition scores (BCS) were also monitored during the experiment. Statistical analysis was conducted using the SAS and SPSS software, and p-values of < 0.05 were considered statistically significant. Two of the nine (22.2%) mares in the Equilume light mask group and three of the 11 (27.28%) mares in the stable lighting group were still cycling in December and January, which were considered as all-year-round cycling mares. On February 15, there was no difference between groups in the resumption of early seasonal estrus cycle, which was determined by follicles > 25 mm in addition to uterine edema. All mares in the Equilume light mask group and five of the eight mares (62.5%) in the stable lighting group had resumed cycling. Interestingly, six of the seven mares (87.5%) in the Equilume light mask and four of eight mares (50%) in the stable lighting group had already ovulated on February 15 (p > 0.05), as determined by the presence of a recent corpus luteum. No difference was observed in BCS and uterine edema between groups (p > 0.05). In conclusion, the Equilume light mask can be an effective approach to induce early seasonal estrus cycles of mares in Jeju Island, and it also enhances the efficiency of farm management by reducing labor.

Through reorganization in 2008, The ministry of Agriculture, Food and Rural Affairs integrated management of the food industry by transferred functions which was scattered in the Ministry of Health and Welfare, and established comprehensive policies covering the primary, secondary, and tertiary industries. In the agricultural industry sector, new business concepts such as smart farm and food tech have recently emerged alongside the fourth industrial revolution. In order for the Ministry of Agriculture, Food, and Rural Affairs to develop appropriate policies for the fourth industrial revolution, it is necessary to accurately estimate the size of agricultural and livestock-related businesses. In 2017, the Ministry of Agriculture, Food, and Rural Affairs initiated research for the agriculture, livestock and food industry's special classification, which was approved by the National Statistical Office in 2020. The estimation of the agriculture, livestock and food industry's size based on special classification is crucial because it has a substantial impact on the formulation and significance of policies. In this paper, the appropriate rate was derived from samples extracted from the special classification and the Korean standard industrial classification. Proposed are a method for estimating the population of the agricultural and livestock food industry, as well as a method for calculating the appropriate rate that more accurately reflects the population than the method currently in use.

This study attempted to provide policy recommendations in promoting new cooperatives established in agriculture based on the 2012 Cooperative Act. A questionnaire survey was conducted with 195 newly established cooperatives as the policy target of this study. The new cooperatives were classified as three kinds namely as 'Business' Cooperatives', 'Consumers' Cooperatives', 'Social Cooperatives' based on their member attributes and objectives. Interesting to note that, all of these new cooperatives born by the new Act has taken the marketing business as their main stream business. Among the three types, 'Business Cooperatives' are ranked the highest amount of capital shares per person in average, having about 30 members in size. In categorization, 'Business Cooperatives' include farmer cooperatives as majority and employee cooperatives. They are usually involved in both production and marketing and even in processing activities, and have tried to secure their business performance by e-commerce and stable business contracts. Their diverse activities are highly associated with their local community. Consumers' Cooperatives include consumer cooperatives and stakeholder cooperatives in achieving welfare of members. This type has lower share in capital but has over 30 members in a cooperative, taking marketing (distribution) business as main and often take advantage of their social network and physical store. Regional relationships are less than producer cooperatives. 'Social Cooperatives' are established by public interest and have around 10 members and lowest per capital. their business and community activity is similar to the consumer cooperatives. This study recommends the needs of designing suitable business models by these three types of cooperatives in the future, while appropriating their membership size for their tangible business operations. The government policy direction should aim to develop their new business opportunities and its management stabilization, especially in conjunction with the existing agricultural cooperatives (Nonghyup). It must be rather than to provide simply policy supports for establishment. An in-depth study is recommended in this regard.
