This study was conducted to investigate the efficacy of freshwater alga, Chlorella fusca on the improvement of growth and qualities in organic spinach and Chinese chives farm. The average height of Chinese chives treated with the chlorella was 3.7 cm smaller than that of the untreated. The leaf width and fresh weight of Chinese chives treated with the chlorella was 0.5 mm wider and 30.3 g heavier than that of the untreated. The commercialization and yield of Chinese chives treated with the chlorella was 11.9% and 18.3%, respectively higher than that of the untreated. Also, the disease severity of gray mold disease of Chinese chives treated with the chlorella was reduced by more than 24.2% when compared with the untreated. The thickness and number of spinach leaves treated with chlorella was 27.9% and 41.8%, respectively higher than that of the untreated. The fresh weight and yield of the spinach treated with the chlorella was 63.6% and 31.5%, respectively higher than that of the untreated. Moreover, the mineral content of K, Ca, Mg, P, Fe, and Mn were recorded higher in the spinach treated with chlorella compared with that of untreated. The results indicated that the freshwater alga, Chlorella fusca is efficient and economical biostimulant in improving plant growth and quality of Chinese chives and spinach in organic farm.

본 연구는 HACCP 제도를 적용하고 있는 소규모, 중규모, 대규모 양돈농장의 HACCP 제도 도입 목적, 효과, 그리고 문제점 등을 비교분석하기 위한 목적으로 실시하였다. 소규모와 중규모 양돈농장은 HACCP 도입 목적의 1순위를 정부의 예산을 지원받기 위함이라고 하였으나 대규모 농장은 농장의 경쟁력 향상이라고 답하였다. HACCP 적용 효과는 소규모 농장의 경우 체계적인 농장관리를 1순위로 응답하였으나 중규모와 대규모 농장은 농장의 위생관리 수준 향상이라고 답하였다. 아울러 HACCP 적용에 따라 발생되는 가장 큰 문제점으로는 직원의 의식향상의 어려움(소규모 농장)과 HACCP 도입에 따른 기록관리(중규모, 대규모 농장)인 것으로 조사되었다. 이러한 문제점을 개선하기 위해서는 양돈농장 HACCP 평가항목 수의 조정과 종업원을 대상으로 HACCP 교육을 실시할 필요성이 있을 것으로 판단된다.

Intensive farming methods that do not guarantee animal welfare can induce stress in pigs. Stress, in turn, can reduce their disease resistance and influence their hormones and metabolites in such a manner that productivity is negatively affected. This study was conducted to compare the stress related factors and blood characteristics of pigs raised on conventional farms and those raised on animal welfare farms. We measured the levels of cortisol, epinephrine and norepinephrine, biochemical parameters in blood and glycogen, L-lactate and heat shock protein 70 (HSP70) in muscle, as physiological markers of indicating the stress in conventional farm pigs (Control, n=10) and animal welfare farm pigs (Welfare, n=10). We found that there was a significant difference in the albumin-globulin ratio (A/G ratio), as well as the albumin (ALB), blood urea nitrogen (BUN) and aspartate aminotransferase (AST) levels between the two farms. Epinephrine was significantly higher in conventional farm, while level of norepinephrine was higher in animal welfare farm. There was no significant difference in cortisol, which is known as a stress hormone, across the two groups of farms. Muscular glycogen content was significantly high in animal welfare farm pigs. While L-lactate tended to be low in the animal welfare farm pigs, the difference between them and the conventional farm cohorts was not significant. HSP70 showed high levels of expression in conventional farm. Thus, we suggested that blood parameter results showed a stress response in the livers of conventional farm, and that catecholamine hormones, glycogen, L-lactate and HSP70 can be used as physiological factors of assessing animal welfare.

In the development of policies and projects for regional development, consolidating region's organization and organizational leadership that could establish and operate voluntary developmental plans along with active participations by regional people are important. There have been successful cases of regional agricultural products emphasizing regional characteristics by strengthening functions and autonomy of the local government based on the premise of increasing mealable relationship among local industries and maximizing the characteristics of local resources and local resource utilization. However, effective pursuing is difficult due to lack of organization and leadership. Centering around local units with their importance recognized playing the core role in the development of rural areas, other important issues are activating civic organizations essential for local development based on town units and agricultural amenity resources in rural areas by seeking methods of rearing organizational leadership, improving rural incomes by strengthening local competitiveness through environmentally-friendly agricultural products based on local units, and developing and activating farm experience related with green tour. The types of organization and leaders are analyzed by investigating approved cases of farm experience. According to the results of the analysis, we seek the methods of promoting organizations and leaders for promoting farm experiences in villages and methods of constructing support organizations for promoting farm experience centering around local government units (such as city, Kun, Eup, Myun and village).

Objective: The aim of this study was to examine the use of outcome-based observations within Assured Dairy Farm scheme (ADF), Soil Association Organic Standards (SA), and cross compliance (CC) farm assessment reports. Methods: A total of 449 ADF reports, 37 SA reports and 26 CC reports were analyzed and their objective comments categorized as either resource-based or outcome-based. Results: A mean of 61.0% of ADF questions were responded to with comments, in comparison to 25.0% of SA and, 21.0% of CC report questions. The SA and CC reports had significantly more outcome-based comments than the ADF (p<0.001). The assessors' tendency of choosing resource-based approach was revealed in the questionnaire results. Conclusion: Generally, the comments were comprehensive and contained professional judgements. Large numbers of comments provided in the ADF reports were mostly compliant and resource-based evidence, which serves as proof of assessment rather than aiding the certifying process. The inclusion of specific welfare outcome measures in the SA inspection likely increased the use of outcome-based comments in the reports, irrespective of whether the farm achieved compliance with a given standards. The CC scheme, on the other hand, focused on providing outcome-based evidence to justify noncompliant decisions.

The Coronavirus disease (COVID-19), first identified in China in December 2019, has widely spread worldwide and is an ongoing pandemic. It is expected that the ripple effect of COVID-19 on the global economy including the agricultural sector will increase substantially if not properly controlled shortly. This study examines the potential impact of COVID-19 on the Korean beef cattle sector and farm labor demand for Korean beef cattle using a dynamic partial equilibrium model. The agricultural production value and farm labor demand for Korean beef cattle in the scenario assuming pessimistic GDP growth rate (-1.2% in 2020) with no direct supply shocks fell by up to 4.00% and 0.67%, respectively, compared to the baseline which represents the future without COVID-19 outbreak. On the other hand, the agricultural production value and farm labor demand for Korean beef cattle in the scenario assuming both pessimistic GDP growth rate and supply shocks (-12.7% beef imports and + 2.4% feed cost in 2020) increased by up to 12.08% and 1.99%, respectively, compared to the baseline.

This study determined the economic impact of environment-friendly cultivation and the optimal cultivation area of Omija (Korean for Schisandra chinensis Baillon) for full-time farmers by analyzing the management performance of existing Omija cultivators. The study divided the target income into urban household income and Omija farm income, and estimate the optimal cultivation area by substituting the target profit from the cost-volume-profit analysis model. The optimum cultivation area was 1.4 ha for general cultivation, 1.08 ha for organic cultivation, and 1.18 ha for pesticide-free farming cultivation considering the average urban household income as the target, and 0.81 ha for general cultivation, 0.63 ha for organic cultivation, and 0.69 ha for pesticide-free farming, considering the average 2012 farm household income as the target. Therefore, the study reached conclusion that it is necessary to secure the price of Omija farm and stable support for income increase. Therefore, the support plan for income stabilization of Omija farm should be considered. Especially, the central government should provide various policies and financial support to help the optimal cultivation area of Omija Farm.
