  • Meat products such as ground meat and freshly packaged meat are known to be one of the primary food sources for foodborne illnesses. While 17 countries internationally allow irradiation treatment to ensure the hygienic safety of these products, Korea currently has no such regulations. In this study, a survey was performed targeting 1,000 individuals from the general public and 70 employees from the industrial sector about the need to establish domestic irradiation treatment regulations for meat products and the perception of food irradiation technology. The results showed that 78.4% of the general public and 81.4% of industrial employees responded that it is necessary to establish irradiation treatment regulations for meat products. The main reason for this was that irradiation treatment can help prevent food poisoning by ensuring the microbiological safety of the products. Besides, 94% of the general public responded that they would purchase irradiated meat products if the regulations were activated, and 66% of industrial employees expressed their intention to use irradiation treatment technology. This response indicates positive public acceptance and industrial applicability of food irradiation technology. In addition, this study suggested that continuous research to ensure safety, promotion, and education through various media had to be conducted as the supplementation for food irradiation technology before its application.

  • 본 논문은 삼동선의 선형특성에 대한 간략한 소개와 삼동선의 주선체 좌우에 설치되는 보조 선체의 위치가 조파저항성능에 미치는 영향과 그 최적위치선정을 위한 연구 결과를 보인다. 조파저항 계산기법을 이용하여 보조선체의 길이방향과 횡방향의 위치 변화에 대한 조파저항을 계산하였으며, 그 유용성을 검증하기 위하여 모형시험결과와 함께 비교하였다 본 연구를 통하여 보조선체의 횡방향 위치가 삼동선의 조파저항성능에 미치는 영향은 작으나, 길이방향 위치는 그 성능에 커다란 영향을 미치는 것으로 나타났다. 그리고 주선체의 선수부에서 발생된 커다란 파도의 파저에 보조선체의 선수가 놓이는 것이 저항성능에 가장 유리하며, 선속이 빨라짐에 따라서 그 최적위치는 선미쪽으로 옮겨가는 경향을 보였다.

  • 선박설계에 컴퓨터를 이용하는 기술이 보편화되면서 선형에 대한 많은 기하학적 모델링 기법이 개발되어 왔다. 그러나 종래의 방법은 일반 선형에 대하여 자유곡면을 부분별 곡선 또는 곡면으로 표현하는 방법이다. 본 논문에서는 기하학적 원형요소들의 인스턴싱과 접합을 이용하여 비 정규 선형에 대한 간편하고 정확한 기하학적 모델링 기법을 개발하였다. 또한 정의된 선형에 대한 기하학적 특성치와 유체정역학, 복원력 등 기본계산을 수행하는 프로그램을 작성하였다.

  • DB Integration website(tentatively named Food Processing Aptitude Information Center, FPAIC) has been designed through a "high-value products development project(2013)". Basically, the project aims to secure connections between food raw materials and processing industry, a variety of information sources, and users's convenience. It also aims to build the industry-university-based mutual growth in the food industry through sharing of processing suitability and material research on food raw materials. FPAIC consists of raw material story, information of sample characteristics, food processing study, preceding research data, food industry trends, and understanding of food processing. The major database of research on Food Processing is provided on information of sample characteristics, and food processing study. Currently the web site has 36 raw material stories, 380 information on sample characteristics and food processing studies, 1,600 preceding research data about 31 food raw materials. The web site also provides information on 70 useful web sites, as well as 77 food industry trends, 27 basic information about food processing.

  • Human Powered Vessel Festival (HPVF) hosted by the College of Engineering of Chungnam National University, the Society of Naval Architects of Korea and the Korea Ocean Research & Development Institute has been held annually in Daejon since 1999. Solar boat powered by solar energy appeared for the first time in 2006, and it is expected that more new teams will enter this competition in the coming years. In this paper it is described that design procedures and manufacture processes of the solar boat named EPISODE. Firstly, It is aimed to understand compositions of the electric system and their performance properties and to show the design procedures using commercial design packages line WAVIS, CATIA, HCAD etc. Through the trial test, we confirmed ship speed, maneuverability, durability and operation condition of the electric system and found some problems. We plans to make reported problems go away and install hydrofoils for more improved speed performance.

  • An approach to model a high-speed monohull vessel is introduced. The high-speed monohull form belonging to the category of multihull is drawing new attention, due to the rapidly growing trend of fast passenger ships and military purpose. Multihull forms are much thinner in their overall shape, compared to those of the conventional commercial vessels. Moreover, the parent hull forms are not readily obtainable when a new design is intended, which makes it hard to perform various technical calculations in terms of hull optimization, hydrodynamic computation, structural design, and so forth. In this paper, a parametric technique is used to design a high-speed hull form. To model a hull form, NURBS (Non Uniform Rational B-Spline) representation is used. The goal of research is to provide a fast and convenient tool to design an initial hull form with fewer parameters available in the early design stage. The technique employed in this paper will be applied to the design of multihull forms, such as catamaran, trimaran, and semi-swath.
