  • The objective of this paper is to introduce on a mobile APP called MAMIS(Marine pollution Accident response Mobile Information System) and it's functions. MAMIS was developed by Korea Coast Guard for marine pollution responder in 2012. Users can get information on marine pollution response easily without being restricted by time and place. MAMIS can be operated by smart phones with Android OS and iOS, both of which are the most popular mobile operating systems in Korea. And it has been developed in the form of hybrid APP which combined the functions of mobile APP and mobile WEB. MAMIS is composed of 9 menus, 5 mobile-based ones and 4 web-based ones. The mobile-based menus are on substance information, clean-up skills, response measures, QR code scanning, and volunteer's safety, and the web-based ones on weather information, response equipment, clean-up materials, and SNS.

  • A country is acutely needed to establish a marine salvage & oil spills response in order to prepare for a large accidents. Although our country depends on a foreign technique when a large marine accidents occur, insufficiency of facilities and technique. With these problems, because of the damage of accidents expands due to not taking proper actions, Accordingly, in case of marine accidents, this paper will suggest a various scheme of infrastructure in salvage & oil spills response system in order for quick and effective salvage & oil spills response, investment of facilities, technical development of salvage & oil spills response, and improvement of ability etc

  • With an entering into force of OPRC-HNS started in June 14th 2007, establishment of response system in a nationwide scale to take care of accidents is required to respond rapidly and effectively. This necessities drove us to analyze national contingency plan for chemicals including national response system against accidents, which is in operation in the US. Main characteristics of the system are well described as an integrated incident command system with a cooperation of responsibilities facilities, manpower, and technical support. In addition, state anψor local authorities tend to have responsibilities on management of disaster with its response activities. Polluters are also charged to pay expenses 3 times expensive provided state or local authorities are conducted. In general, response activities are conducted by private sectors. However, the government will take action with Superfund if the response capacity is over than the polluters can. However, safety are regarded as a primary factor to be considered in the response activities, and try not to recover any pollutants. Personals belonging to USCG and EPA are required to complete specialized courses to promαe professional skills, and are also welcomed to participate in "certification program"

  • The purpose of this study is development of the sprayer that can effectively control pathogens. Image processing was used to analyze the sprayer. Experimental paper in the form of $5{\times}7$ 10 m intervals total of 35 sheets were installed. Experiment used binarized image data obtained by sprayed pigment, to analysis spray volume and distance. The experimental results show that 60 m distance was available to the spray. And spray rate was high up to 30 m. It can be used in livestock farms are expected.

  • This study was prevent the decrease in crop output by insect pests and spraying by application uniformity. A flight level 4 m height and 4-5 m/sec. speed are difficult to maintain with a agricultural drone for aerial application, which has been affected by the methods or environmental factors, such as changes in the wind. Therefore, which can allow a controlled application width and spray rate automatically and verified experimentally using drone. The sprayed particles began to decrease from about 3.75 m on the left and right sides of the spray nozzle. According to the number of particles, the effective spraying width was observed to be about 7.5 m, and it was verified that the proposed spraying system was effective in uniform control system.

  • 9$\cdot$10월은 중$\cdot$만생종의 수확기이다. 이제까지의 고된 작업과 병해충과의 씨름도 어느정도 마무리 단계에 접어들게 되나 아직까지도 자칫 방심하면 다지어 놓은 농사를 망치기도 하고 조기낙엽에 의하여 내년도의 개화결실에도 나쁜 영향을 미치게 된다. 따라서 작업의 선후를 잘 계획하여 한 해의 농사를 마무리 지어야한다. 9$\cdot$10월의 중요한 과수원작업은 착색관리, 적기수확 및 저장, 추비시용인데, 병해충이 많을 때에는 약제방제도 소홀히 할 수 없으며, 태풍의 피해가 우려되는 과수원에서는 이에 대한 대비도 하여야 한다.

  • Control drones, which are recently classified as smart agricultural machines in the agricultural field, are striving to build smart control and automatic control systems by combining hardware and software in order to shorten working hours and increase the effectiveness of control in the aging era of rural areas. In this paper, the characteristics of the nozzle dedicated to the control drone were analyzed as a basic study for the establishment of management control and automatic control systems. In order to consider various variables such as the type of various drone models, controller, wind, flight speed, flight altitude, weather conditions, and UAV pesticide types, related studies are needed to be able to present the drug spraying criteria in consideration of the characteristics and versatility of the nozzle. Therefore, to enable the consideration of various variables, flow analysis (CFD) simulation was conducted based on the self-designed nozzle, and the theoretical and experimental values of the droplet distribution were compared and analyzed through water reduction experiments. In the future, we intend to calculate accurate scattering in consideration of various variables according to drone operation and use it in management control and automatic control systems.

  • 당근은 미나리과에 속하는 직근성 채소로서 비타민A가 다량 함유된 건강식품으로 우리나라에 6,000㏊ 내외로 재배되고 있다. 재배지역은 우리나라 전체 재배면적 중에서 남제주군 지역이 44.5%, 경남 김해, 양산지역이 16.1%, 강원 평창지역이 11.1%를 점유하고 있으며 총 재배면적의 70% 이상이 주산단지 화되어 있어 기계화가 용이한 작목이다. 당근재배에 있어서 10a당 작업단계별 노동투하시간을 보면 전체 100.2시간으로 경운정지, 방제작업만 기계화가 이루어지고 대부분 인력에 의존하고 있는 실정이다. (중략)
