  • Objective: This study was conducted to investigate the effects of dietary corn resistant starch (RS) on the intestinal morphology and barrier functions of broilers. Methods: A total of 320 one-day-old broilers were randomly allocated to 5 dietary treatments: one normal corn-soybean (NC) diet, one corn-soybean-based diet supplementation with 20% corn starch (CS), and 3 corn-soybean-based diets supplementation with 4%, 8%, and 12% corn resistant starch (RS) (identified as 4% RS, 8% RS, and 12% RS, respectively). Each group had eight replicates with eight broilers per replicate. After 21 days feeding, one bird with a body weight (BW) close to the average BW of their replicate was selected and slaughtered. The samples of duodenum, jejunum, ileum, caecum digesta, and blood were collected. Results: Birds fed 4% RS, 8% RS and 12% RS diets showed lower feed intake, BW gain, jejunal villus height (VH), duodenal crypt depth (CD), jejunal VH/CD ratio, duodenal goblet cell density as well as mucin1 mRNA expressions compared to the NC group, but showed higher concentrations of cecal acetic acid and butyric acid, percentage of jejunal proliferating cell nuclear antigen-positive cells and delta like canonical Notch ligand 4 (Dll4), and hes family bHLH transcription factor 1 mRNA expressions. However, there were no differences on the plasma diamine oxidase activity and D-lactic acid concentration among all groups. Conclusion: These findings suggested that RS could suppress intestinal morphology and barrier functions by activating Notch pathway and inhibiting the development of goblet cells, resulting in decreased mucins and tight junction mRNA expression.

  • The purpose of this study was to explore the relationship between agricultural insurance, agricultural loans, and the agricultural industry and find ways to consolidate and improve the interactive development between these three systems. We collected relevant data from 2009 to 2019 in 15 provinces of China and constructed a coupled coordination model to analyze the data. The results are as follows: First, the eastern part of China was ahead of the central and western parts in terms of agricultural loans and the agricultural industry, while the western part was ahead of the central and eastern parts in terms of agricultural insurance. Second, the coupling degree of the three systems in all 15 provinces reached an extremely high level. Third, all 15 provinces showed an overall continuous rise in coupling coordination degree. In 2019, eight provinces reached the medium-level coupling coordination development, and seven provinces were in a state of barely coupling coordination development. The three systems formed a mutually reinforcing relationship and basically entered a state of coordinated development. Finally, there was a great development gap between different regions of China concerning the coordinated development of the three systems, therefore, innovative development is urgently needed to further promote the coordinated development level.

  • Bioindustry is rapidly changing. Many biologists redefine biotechnlolgy as 'reprogramming the genetic codes of living things to suit cultural and economic needs and desires.'We regarded this change as the 'paradigm shift'in bioindustry. The genome research is reorganizing agricultural and environmental industries as well as a pharmaceutical industry. By analysing patent data granted in the United States from 1997 to 1999, we tried to explore the international patterns and trends of technological innovation in bioindustry, especially in the genome research. As the result, we could find that the United States'monopolistic position in the bioindustry was consolidated by the genome research. Competitive positions in the countries such as Japan and Germany, however, have been aggravated continuously. Korean inventors weren't also active in many biotechnological areas as comparing to developed countries such as US and UK. Especially, the gaps between Korea and developed countries in genome research were greater than any other areas.

  • Purpose - This paper discusses the effectiveness of EcoFarmer in Zimbabwe. The effectiveness of EcoFarmer still needs to be established because it is a new product that is hardly a month old. Research design, data, and methodology - The paper follows a qualitative research methodology and an exploratory approach to establish the effectiveness of EcoFarmer in the promotion of productivity in the agricultural sector in Zimbabwe. Using an Internet-based literature review, the paper explored the link that exists between Econet's EcoFarmer program and agricultural development in Zimbabwe. Results - The findings are that the innovation promotes agricultural productivity. This is in line with what was established by Safaricom Foundation in Kenya. Conclusions - The paper used literature sources because the phenomenon is exploratory. This limitation could have been avoided by using a field survey. The paper shows that the EcoFarmer is an innovative project that was developed by Econet as a replication of the Kenyan program.

  • Asan city has many strengths, for examples, the distinction of innovation ability, several places with clean environmental resources, conventional-cultural resources and favorable conditions of location in regional agriculture development. But it has not devised the comprehensive development plan for regional agriculture that is integrating natural, cultural and industrial resources. So the plan linked with those resources should be to promoted to develop agricultural production, marketing and regional economy. And a development strategy is to have the system of agricultural independence within Asan. Namely, originality, identity and cooperative spirit in economic and social-cultural aspects of Asan agriculture are needed, which are a great help to settle agricultural issues in Asan itself And the governance system needs to be introduced that has the main bodies of Asan agriculture, so as to promote agricultural policy.

  • 디지털 경제로의 전환을 위해 사회 전 분야에 걸쳐 패러다임의 대전환이 이루어지고 있다. 현재 시점에서 농업도 4차산업혁명의 핵심자원인 빅데이터를 활용하여 혁신 성장을 이루고자 글로벌 농산업계는 다양한 움직임이 일어나고 있다. 국내도 정부 차원으로 빅데이터 활용 촉진을 위해 다양한 시도를 시행하고 있으나, 빅데이터 활용 핵심 주체인 농산업계의 움직임은 아직 미흡한 실정이다. 이에 본 연구에서는 농업 관련 기업 종사자를 대상으로 빅데이터 활용 시 얻을 수 있는 경제적 혜택과 실용적 혜택을 조절변수로 하여 통합기술수용이론에 근거한 성과기대, 노력 기대, 사회적 영향, 촉진조건과 혁신성향이 빅데이터 수용 의도에 미치는 영향을 분석하였다. 농업 관련 기업 종사자를 대상으로 수집한 설문지 333부를 실증분석에 사용하였다. SPSS v22.0과 Process macro v3.4를 사용한 분석결과는 첫째, 노력 기대, 사회적 영향, 촉진조건 및 혁신성향은 빅데이터 수용 의도에 정(+)의 방향으로 유의한 영향을 미치는 것으로 나타났고, 성과기대가 수용 의도에 미치는 영향은 유의하지 않은 것으로 나타났다. 수용 의도에 사회적 영향이 가장 크게 영향을 미치고 혁신성향이 가장 작게 영향을 미치는 것으로 나타났다. 노력 기대와 수용 의도 간의 경제적 혜택과 실용적 혜택의 조절 효과, 사회적 영향과 수용 의도 간의 실용적 혜택의 조절 효과, 촉진조건과 수용 의도 간의 경제적 혜택과 실용적 혜택의 조절 효과는 유의한 것으로 나타났다. 반면에 경제적 혜택과 실용적 혜택은 성과기대와 혁신성향이 수용 의도에 미치는 영향력의 크기를 조절하지 않는 것으로 나타났다. 이러한 결과를 통해 다음과 같은 시사점을 제시하였다. 첫째, 기업의 빅데이터 활용 촉진을 위해 정부는 기업 맞춤형 정책 수립을 준비할 필요가 있다. 맞춤형 지원을 통해 기업 구성원들이 빅데이터 활용에 대한 올바른 이해와 공감대를 형성해야 유의미한 성과를 만들어 낼 수 있기 때문이다. 둘째, 농업 데이터 특화된 플랫폼 구축, 표준화 방식 기반으로 데이터 연계, 데이터 접근에 대한 단일화 창구 지원을 마련해야 한다. 이러한 플랫폼 구축은 기업 간 주체적인 협력 관계를 형성하여 산업을 고도화시킬 수 있을 것이다. 마지막으로 본 연구의 한계점과 후속 과제를 제시하였다.

  • This study aimed to analyze educational satisfaction and the relationship between learning transfer and learning persistence shown after actual education targeting students who participated in the agricultural education and training. Conclusions based on the study results can be suggested as follows. First, of the factors related to learning persistence, satisfaction of educational contents turned out to be a statistically significant factor with a positive effect in the agricultural education and training. Students participating in the agricultural education and training have a conspicuous object to learn for improving ability which is necessary for and applicable to agriculture. Second, of the three factors related to learning transfer in the agricultural education and training, satisfaction of educational contents, educational facilities and satisfaction of environment turned out to have a positive effect. Third, results show that satisfaction of instructors does not affect both learning persistence and learning transfer. Lastly, in case of education and training for field practice, this study is suggesting the necessity of research by accessing in a concrete and detailed manner such as learning contents, instructors, educational facilities and satisfaction of environment from the comprehensive concept of educational satisfaction in the directivity of study related to satisfaction.

  • The ascomycete fungus Colletotrichum gloeosporioides infects a wide range of plant hosts and causes enormous economic losses in the world. The transcription factors (TFs) play an important role in development and pathogenicity of many organisms. In this study, we found that the C2H2 TF CgCrzA is localized in both cytoplasm and nucleus under standard condition, and it translocated from cytoplasm to nucleus in a calcineurin-dependent manner. Moreover, the ΔCgCrzA was hypersensitive to cell wall perturbing agents and showed severe cell wall integrity defects. Deletion of the CgCRZA inhibited the development of invasive structures and lost pathogenicity to plant hosts. Our results suggested that calcineurin-responsive TF CgCrzA was not only involved in regulating cell wall integrity, but also in morphogenesis and virulence in C. gloeosporioides.
