Consumer's concerns over beef safety are increasing according to resuming U.S. beef import. And a few beef producers have converted into organic beef recently. This organic beef must have taste, nutrition and safety that consumers demand for. Korean organic beef should be gone on sale at the shop under direct management of producer's organizations or the special shop for Environmentally friendly products. So they should win consumers' confidence for beef safety and transparency in producing and marketing process.

This study focused on production and distribution situations of Korean organic beef cattle at Hongseong Chungnam. Case Farmers have raised cattle organically based on interchange between a few Consumers' Life Cooperatives(CLC) and them. CLC furnished with funding to purchase calves and bought the cattle beef. However, they have many problems related to procuring organic feed in producing organic beef. Presently, they have used organic byproducts from sowing farming and prepared grass places. But they don't breed organic beef cattle in a large scale because of the limitation of organic feed output.

Producing Korean organic beef cattle costs a great deal because it needs breeding conditions like the organic feed, an uncontaminated breeding farm and so on. So the price of Korean organic beef (KOB) is more expensive than that of Korean general beef (KGB). To overcome this adverse price condition, a case production organization in Asan will choose direct marketing routes for consumers or the shop under direct management of the organization, or franchise shops. As a result, these marketing routes are expected to narrow the price gap between KOB and KGB. And consumers will accept the price of KOB if quality of KOB is very high level, for example the first grade++.

This study examines how consumer attitudes toward food origin and health concerns influence beef purchasing behavior. Using data from the Korea Rural Economic Institute's food consumption behavior survey, we analyzed the frequency of purchasing domestic and imported beef. Results indicate that when not distinguishing between domestic and imported beef, perceptions of lower origin quality and higher health concerns are associated with an increase in purchasing frequency. However, such influences are statistically insignificant for imported beef. Further analysis reveals that for consumers exclusively purchasing domestic beef, these factors do not significantly impact purchasing frequency, while for consumers simultaneously purchasing both domestic and imported beef, these factors do significantly impact purchasing frequency.

The present study investigated the combined effects of modified atmosphere packaging (MAP) and organic acid salts on the quality and shelf-life of Hanwoo ground beef patties. The ground beef containing 500 ppm of ascorbic acid was prepared with air-packaging (Air-P), high oxygen-MAP (70% $O_2$+30% $CO_2$/OxyMAP), and nitrogen-MAP (100% $N_2$/NitroMAP), in combination with organic acid salts (1500 ppm of sodium acetate and 500 ppm of calcium lactate). The samples were stored for 11 d at $5^{\circ}C$. The pH value of ground beef patties decreased during storage in all the treatments. The ground beef patties with organic acid salts showed relatively higher level of pH during storage compared with non-added patties (p<0.05). Lipid oxidation was accelerated in OxyMAP while it was delayed in NitroMAP treated with organic acid salts. Nitro-MAP treated with organic acid salts was effective in stabilizing the color characteristics of lightness (CIE $L^*$) and redness (CIE $a^*$) during storage. Oxygen content in MAP was shown to be a more important factor affecting color stability and lipid oxidation of ground beef than organic acid salts. The aerobic and anaerobic bacterial counts were reduced both in OxyMAP and NitroMAP (p<0.05), and the lactic acid bacteria was inhibited by Oxy-MAP (p<0.05). Coliform bacteria decreased during storage as pH value was decreased in all treatments. According to the sensory evaluation, the ground beef patties in NitroMAP showed the best quality among all treatments during storage. Therefore, Hanwoo ground beef patties added with sodium acetate and calcium lactate and packed with NitroMAP showed better quality characteristics than other treatments. This packaging method is recommended and could be utilized for packaging hanwoo ground beef patties for improving quality and extending shelf-life.

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.

The purpose of this study was to assess the causal relationships among belief, subjective norm, moral feeling, attitude, and the intention to consume organic beef. A total of 326 questionnaires were completed by adult in Jeonnam area. Structural equation modeling was used to measure the causal relationships among the constructs. The structural analysis results indicated an excellent model-data fit. The covariance effects of belief and subjective norm, and belief and moral feeling were statistically significant. The effects of belief and moral feeling on attitude and intention to consume were also statistically significant. As expected, attitude had significant effects on intention to consume. Moreover, attitude played a mediating roles in the relationship between belief and intention to consume. Finally, based on structural analysis, a model was proposed for the interrelations among belief, subjective norm and moral feeling towards organic food, attitude and intention to consume. It should be noted that the original organic food consumption model was modified, and should preferably be validated by future research. Other constructs, such as perceived behavior control and consumption, may be incorporated to form models that consist of new antecedent and consequence pairs.

The Korea-US FTA was one of the most controversial FTAs Korea has ever signed and was expected to have a significant effect on the agriculture sector, especially the livestock industry. This study ex-post analyzed the impact of the Korea-US FTA on the Korean beef industry including the Jeonnam province using a dynamic partial equilibrium model. According to the scenario analysis results, if there was no Korea-US FTA, the beef imports would be reduced to as low as 0.24% to 4.19% compared to the Baseline applying existing Korea-US FTA beef tariff rates over the 2012 to 2022 periods. In addition, if there was no Korea-US FTA, the agricultural product value of Jeonnam and national Korean beef cattle would increase from 0.25% to 7.37% and 0.25% to 7.33%, respectively, compared to the Baseline. The results of the analysis are expected to be used as important information for policy establishment in preparation for CPTPP and supplementation of current FTA policies regarding Korean beef cattle not only for the central government but also Jeonnam province.
