본 연구는 한국농수산대학 전공심화과정 졸업생들의 영농활동 실태에 대한 분석이다. 분석 결과 한농대 전공심화 졸업생들의 영농활동 특징으로는 규모화 전략을 통한 농업경쟁력 확보에 노력하고 있으며, 이를 기반으로 전문영농에 힘쓰고 있다. 또한 다양한 농업기술혁신 전략을 통해 가치창조 농업(예를 들면, 친환경농업, 신기술의 적극적 도입, 지속적인 연구 활동, 지역사회 활성화에 견인, 전문가 및 동문 등과 적극적인 네트워크 활동 등)에 앞장서고 있다. 그리고 이러한 노력들은 다양한 인증 및 수상(무농약 인증, 무항생제 인증, 우수농가 수상, 우수농산물(GAP), HACCP 인증)등의 결과로 나타나고 있다. 이렇듯 전문 고등교육기관에서 농업에 대한 체계적인 교육을 받은 한농대 졸업생들의 역할은 향후 우리나라 농업발전에 있어 매우 큰 역할을 수행할 것으로 예상된다. 따라서 이에 대한 학교 측의 다양한 제도적·정책적 지원이 수반되어야 할 것이다.

This study was conducted to investigate the seed storage method and seed germination characteristics of Synurus deltoides (Ait.) Nakai, a kind of wild vegetables. Several parameters affecting seed germination, such as germination temperature, chilling duration, imbibition duration, and storage method were evaluated. The seed germination of Synurus deltoides showed the highest germination rate (GR), promptness index (PI), germination performance index (GPI), mean daily germination (MDG) at 25℃. This implies that the optimum germination temperature was 25℃. And also, Seeds stored at -4℃, after 150 days showed relatively high germination rate about 98%. Therefore, The optimum germination temperature of Synurus deltoides was 25℃ and to increase the germination rate over 98% of Synurus deltoides, cold-wet storage 20 days treatments at 4℃ were effective in the improvement of seed germination.

This study was conducted to develop the hanging type circular-patterned system that at maximizing the spatial efficiency of strawberry cultivation to increase yields, while also reducing labor and improving energy efficiency. The system consists of a cultivation bed units, longitudinal moving device, bed lifting device, front and rear transfer devices, lateral transfer device, nutrient supply device, and control unit. Performance testing revealed that the operational motor for longitudinal movement should have a torque of at least 0.1Nm based on the design weight and traction force of the cultivation bed unit. The power consumption required to move one cycle was calculated to be approximately 149Wh when performing harvesting or maintenance tasks for all 10 cultivation beds. Vibration angles measured during bed movement showed that the lateral transfer resulted in a roll angle ranging from -0.62° to 0.68° and a pitch angle ranging from -3.79° to 5.26°. For longitudinal transfer, the roll angle ranged from -3.37° to 3.36°, and the pitch angle ranged from -0.45° to 0.49°.

In this paper, we surveyed the service system disclosed by the government and self-governing province to analyze the status of IoT data service. Survey conditions were focused on data generated from objects such as sensors, OpenAPI that can utilize the generated data and data having a data update cycle of less than 1 month. As a result of the survey, the ratio of IoT data to data released by the government, self-governing province and the private sector was only 1.2%. Therefore, in order to increase the utilization with the development of IoT technology, a dedicated organization that can manage the IoT data service is needed.

This study was carried out to establish a proper cultivation site and to diagnose the drought tolerance of Oplopanax elatus leaves by using pressure-volume curves. As a result of analysing data measured, the leaf of Oplopanax elatus showed the osmotic pressure at full turgor(Ψosat) was -0.77 MPa, and the osmotic pressure at incipient plasmolysis(Ψotlp) was -0.90 MPa. Then, the value of maximum bulk modulus of elasticity Emax was 3.7 MPa, showing that slightly lower drought tolerance of Oplopanax elatus. Furthermore, the values of relative water contents RWCtlp and RWC^* were above 80%, showing that the function of osmoregulation is somewhat better. Thus, responses to water relations such as Ψosat, Ψotlp, Emax, RWCtlp and RWC^* of Oplopanax elatus showed relatively lower drought-tolerance property indicating that those growth are appropriate in high moisture soil sites.

The pollution in the coastal sea is being aggravated because of frequent happening of red tide and oil leakage from tankers. The Exclusive Economic Zone is being drawn in the seas surrounding Korean Peninsula. Therefore, the fisheries in Korea is under a great change in their production base. On the other hand, the fisheries have been considered as a part of agriculture in policy making and financial support. The thesis compares agriculture with fisheries in the fund demands and financial supports. It tries to find a way in the efficient allocation of fund for the two industries. The fund demand of a typical fishing household is greater than that of a typical farm household. The fund used by a fishery household is more dependent on debt than that of a farm household. Therefore, the internal financing ability of a fishery household is weaker than that of a farm household. The repaying ability of a fishery household is weaker than that of a farm household because a fishery household's income is less than a farm household's. When we analyze the uses of fund, the fishing industry has some disadvantage in fund uses. The financial support for the fisheries' structural change is weaker than that for agriculture. The fishing industry has some disadvantage in the investment and subsidy rates. Also, the loan period for fisheries is shorter on average than that for agriculture. When we analyze the sources of the fund, the fisheries' banking sources are greater than the government's sources, which is relatively stable. Therefore, the fisheries will be more heavily affected by the liberalization of banking industry and system than the agriculture will. The government needs to change the shortcomings in the sources and uses of fund. First, it needs to use the fund, considering the characteristics of the industry and producers' financing ability. Second, it needs to adjust the sources of fund to the liberalization of financial system.

Research and technology has been transforming the agriculture to agribusiness which encompasses all operations with all the connections from faming per se, to manufacture & distribution of production supplies and farm commodities. Further, with the revolutionary development of information technology in the last two decades, we cannot talk about agribusiness process alone without considering the information technology embedded in the artifact, process, and structure. Despite the emergence of precision agriculture (PA) which is supported by IT based innovations which can not only improve efficiency in farming operations but also contribute to environmental sustainability, the adoption of IT among farmers and in agriculture industry are rather low than expected. Thus, Korean government has been seeking to converge IT into food, agriculture, forestry and fisheries to improve the competency of the agribusiness, and much progress has been made. This paper investigated the status quo of the current IT convergence with Food, Agriculture, Forestry and Fisheries in Korea, and further proposed future policy directions.
