  • Purpose - With the technology of the 4th industrial revolution, business models of agricultural sector are changing rapidly toward convergence and high value-added business models due to the 6th industrialization of agricultural. Our goals is to examine the 6th industrialization of agriculture, and then to apply the technology of the 4th industrial revolution to the 6th industrialization of agriculture, suggesting the possibility of future agriculture, and then linking the export competitiveness of agricultural products. Research design, data, and methodology - As the methodology, case studies and empirical analyzes were conducted as well as literature studies. The case analyses included tomatoes, pig breeding farms, and an empirical analysis was conducted using the AHP analysis by experts of the 6th industrialization. In addition, using 124 survey data, this study examined and analyzed the items of the 4th industrial revolution technology for the 6th industrialization of agriculture and the strengthening of export competitiveness. Results - Results showed that the technology of the 4th Industrial Revolution helped "6th industrialization of agriculture" and "the strengthening of export competitiveness" using two successful cases. The AHP analysis was also carried out, and it was found that the improvement of the technology in the 4th industrial revolution could contribute to the future industrialization as well as the 6th industrialization of agriculture. First of all, we looked many conditions were important and urgent. Among the technologies of the 4th industrial revolution, the mobile, big data were important. Moreover, it was recognized that linkage and convergence related efforts would greatly contribute to strengthening export competitiveness of agriculture such as price and quality competitiveness. Conclusions - The 4th industrial revolution such as hyper-connectivity, hyper-intelligence and hyper-predictability contribute greatly to the 6th industrialization of agriculture, and therefore it is essential to improve the competitiveness of the agricultural sector by using the technology of the 4th industrial revolution. In particular, based on analyses of the diamond model, the "demand conditions" was the most important factor for the activation of the 6th Industrialization, and then "related and supporting fields", "factor conditions" and "business context" were followed in order. The results of this study can be useful for policy, practical and academic sectors.

  • 본고에서는 농서 6종류에서 나타나는 축산관련 전통농업기술을 가축위생, 사육관리, 사료급여, 기타 4개 분야로 나누어 261개를 도출하였다. 축산전문가가 이들 항목 중 개발가치를 인정한 228개 기술을 대상으로 델파이기법을 이용하여 평가영역별로 우수항목(3.0이상)을 도출한 결과, 유용성 영역이 35항목, 과학성 영역이 31항목, 경제성 영역이 18항목으로 나타났다. 이들 3개 영역 모두에서 3.0이상의 평가를 받은 우수기술18개와 전문가가 추천한 5개를 합하여 최종적으로 현대화 가능 기술 23개를 선정하였다. 한편 이들 농업기술을 유형별로 목록화하여 상응분석을 실시한 결과는 '지속영농기술', '과학성 검증', '현대화 기술 개발', '지식재산권화' 는 모두 가까이 위치해 있고, '경제성 고려' 요인만 별도로 떨어져 있다. 이러한 분석결과는 전통농업기술이 지속가능한 영농기술로 현대화, 지식재산권으로 보호받기 위해서는 현대과학의 과학적인 검증과 '경제성'을 고려한 검토가 필요하다는 것을 시사하는 것이다.

  • This study analyzes the factors affecting farmers' recognition and acceptance of sustainable agriculture. To accomplish the objectives of the study a farm survey was conducted using target respondents which were made of the local correspondents and reporters of Korea Rural Economic Institute. The Heckman's model was employed for an empirical analysis on determining the extent of farmers' acceptance of sustainable agriculture. The analysis results show that the more farmers think it is important for Korea to adopt sustainable farming practices, the more they adopt sustainable agriculture. It is also shown that the high incomes farmers earn, the more interest they have in the environment and thus the more likely they are to adopt sustainable agriculture. Based upon the empirical results it is suggested that an adoption of economic incentive instruments, education of sustainable agriculture, research and development of sustainable agriculture technology, and an establishment of sustainable agriculture infrastructure to expand the scale of sustainable agriculture.

  • Leuconostoc mesenteroides is a heterofermentative Grampositive bacterium that plays key roles in fermentation of foods such as kimchi, sauerkraut, and milk, leading to the production of various organic acids and aromatic compounds. To study the microbiological and genomic characteristics of L. mesenteroides, we have developed a new chemically defined minimal medium by using the single omission technique. During the exponential cell growth, this species required glutamine, methionine, valine, and nicotinic acid as essential nutrients and 8 amino acids (arginine, cysteine, histidine, leucine, phenylalanine, proline, threonine, and tryptophan), 5 vitamins (ascorbic acid, folic acid, inosine, calcium panthothenate, and thiamine), and others (manganese, magnesium, adenine, uracil, and Tween 80) as supplemental nutrients. This medium is useful to study the metabolic characteristics of L. mesenteroides and to explain its role in food fermentation.

  • This study focused on the measurement of the actual charging state of ambient aerosol particles, which is important for understanding the intricate process of adverse health effects caused by particulate matter (PM). The net electrostatic charging state of $PM_{2.5}$ collected on filter media was measured in this study. The Faraday cage method and surface potential measurements were used in this study. The results showed that the polarities of the net charging state measured using these two methods were in agreement for 42 out of 48 samples (87.5%), and 36 samples (75%) were negatively charged. The filters were not significantly charged by friction between the filters and air not containing PM. Charge addition to or leakage from the filters was not observed over a two-month storage period. Net charging state of $PM_{2.5}$ collected on the filters was concluded to be negative in most cases, based on data's support of the assumption that aerosol charging state is not altered by the process of PM collection using filter.

  • The objective of this study were to assess rooftop urban agriculture and analyze the differences in soil, growth, physiology, and productivity to elucidate the effect of companion planting with various plants, including lettuce (Lactuca sativa), rosemary (Salvia rosmarinus), marigold (Tagetes patula), Korean perilla (Perilla frutescens), and garlic chives (Allium senescens). Measurements were taken every other week from May to August 2023, totaling eight measurement. Regarding the characteristics of the soil planted with lettuce and aromatic plants, the combined planting of lettuce and garlic chives created a favorable soil environment for plant growth. Consequently, the best growth was observed when lettuce and garlic chives were companion planted. Companion planting of lettuce and garlic chives appears to be the most efficient concerning growth and physiology. The productivity of companion planting lettuce and aromatic plants also showed high-quality lettuce when lettuces and garlic chives were companion planted. Therefore, companion planting of lettuces and garlic chives in rooftop urban agriculture is suitable for growth, physiology, and productivity.
