시설원예에 있어서 자동화는 피해서 갈 수 없는 길이다. 현재 비가림시설 등을 제외하면 인력만으로 관리할 수 있도록 되어 있는 시설에서의 생산이 충분한 이익을 올린 예는 거의 없다. 어느 정도 이상의 규모의 시설을 원활하게 관리ㆍ운영하기 위해서는 자동화가 필요하다. (중략)

식물의 광반응은 광질과 광강도에 따라 상이하며, 광은 열을 동반하게 되므로 광만을 분리하여 생각할 수 없다. 즉, 광은 식물체의 체온과 엽온을 높이고, 잎의 수증기 장력을 증가시켜 증산을 촉진하므로 기화열을 발생하는 원동력이 되기도 한다. 따라서 광은 잎속의 수분이나 기공개도 등에 영향을 주기 때문에 광합성속도에 간접적인 영향을 미치기도 한다. (중략)

Bacillus pumilus is one of the most characterized microorganisms that are used for high-level production of select industrial enzymes. A novel B. pumilus SCU11 strain possessing high alkaline protease activity was obtained in our previous work. The culture supernatant of this strain showed efficient dehairing capability with minimal collagen damage, indicating promising potential applications in the leather industry. In this study, the strain's extracellular proteome was identified by LC-MS/MS-based shotgun proteomic analysis, and their related secretory pathways were characterized by BLAST searches. A total of 513 proteins, including 100 actual secreted and 413 intracellular proteins, were detected in the extracellular proteome. The functions of these secreted proteins were elucidated and four complete secretory systems (Sec, Tat, Com, and ABC transporter) were proposed for B. pumilus. These data provide B. pumilus a comprehensive extracellular proteome profile, which is a valuable theoretical and applicative basis for future genetic modifications and development of industrial enzymes.

대부분의 과채류가 그러하듯이 신선도는 상품가치 판단기준의 가장 중요한 척도중에 하나이다. 현장에서 생산된 상태로 소비자에게 가장 빠른 유통경로를 통해서 공급되는 것이 가장 바람직하지만, 때로는 그렇지 못하는 경우도 생긴다. 따라서 가능하면 수확, 운반, 저장시에 신선도를 오래 유지할 수 있도록 만드는 것이 여러 가지 측면에서 유리하다. (중략)

최근 농업인구의 변화 및 노동력의 감소라는 현실적인 문제를 고려하여 농산물 수확에 있어서 자동화기술의 도입은 필수적이라고 하여도 과언이 아니다. 생물생산시설의 자동화를 위해서는 여러 분야에서 연구가 필요하겠지만, 그 중에서도 수확하고자 하는 대상물의 인식은 수확기 개발에 있어 가장 먼저 선행되어야 할 부분이다. 농업생산을 위한 기계화 및 자동화는 우리 나라 농업의 경쟁력확보를 위해서 가장 절실하게 요구되어지고 있으나 농산물의 수확에는 거의 자동화가 일어나지 못한 실정이다. (중략)

The chlorinated dioxins and furans have attracted considerable scientific and public concern because of their environmental persistence and super-toxicity through the foodchain. Recent dioxin scandals in several military bases have also contributed to a higher awareness on the side of food consumers as well as foodwaste combustion. However, there is continuing uncertainty over the relative importance of different sources of dioxins and furans to the soil environment. In difference to those awareness there is a main influence of potential soil contamination on the dioxin contents in groundwater. It is, therefore, important to provide a sound scientific framework and basis by which to evaluate the significance of the presence of dioxin in soils. Consequently, we have to identify the characteristics and nature of dioxin released into the soil environment, especially in agricultural aspect.

A remote controlled sprayer has designed, manufactured and experimented to spray well on pear trees with pesticides. This study was executed to automate pest management of pear trees. Types of spray nozzle, which was used on the system, were analyzed experimentally to find an optimal spray equipment configuration with several nozzles. Attributions of ultrasonic sensors were analyzed to adjust spraying distance of an unmanned sprayer system. This paper investigated shapes of pear trees and cultivating environment of pear orchard. In order to select optimal spray environment, liquid distribution was measured while angle of nozzle was changed. Additionally, liquid distribution by distance and sprayed liquid capacity by side distance were measured. According to information of shapes of pear trees and cultivating environment of pear orchard, sprayer frames of an unmanned sprayer system were manufactured and sprayer frames were suitable for interval of pear trees. The sprayer system could adjust width of sprayer frames to 2.5 m and height of sprayer frames to 1.7 m. Optimal angle of nozzle, and optimal distance between objects and nozzle were $15^{\circ}$ and 0.8 m. When side distance was placed from 1.2 m to 1.8 m, sprayed capacity reached to the highest amount.

The Norwegian coastal area is the most efficient region for fishery production in the world's oceans, the Norway is the world's top 10 fisheries countries through efficient fishing and fishing aquaculture technology and its scientific management of fisheries bio-resources, with Norwegian salmon having attained the world's highest level. In the late 1980s, fisheries resources were depleted due to overfishing and fish diseases, resulting in a crisis in the fishing industry that lasted until the early 1990s. Since the national fishery emergency, people involved in the fishing industry, including fishermen, research scientists, and government officers, have tried to overcome the challenges facing the industry and identify an appropriate management model for fisheries bio-resources in the Norwegian coastal area. First, research vessels were used to monitor water and sediment conditions and fishery species, with the long-term aim of predicting fishery resources in real time and collecting information on species diversity, abundance, and distribution. Second, a "Healthy Fish Project" was promoted to counter natural disasters and fish disease problems with the development of vaccines against viruses and bacteria, eventually allowing for a decrease in the use of antibiotics and the production of notably healthier fish in the 2000s. Third, a systematic management model was developed to help with preparations for decreases in the total number of fishermen and increases in the proportion of elderly fishermen in the fishery industry using the development of automatic fishing aquaculture systems and short-chain systems. We could learn from the Norwegian model of fisheries bio-resources, management and could adopt it for the preparation of fishery bio-resources management policy for South Korean coastal areas in the near future.
