This study quantitatively analyzes risks of industrial incidents to fisher on overseas tuna purse seiners and long liners. A Bayesian network is employed to analyze 478 cases of industrial incidents, comprising 401 cases from purse seiners and 77 cases from long liners, reported from 2019 to 2022. The highest risk of industrial incidents on purse seiners is attributed to diseases. Excluding diseases, risks are the highest during fishing: 5.31 times higher during catch handling, 2.05 times higher during maintenance, and 2.38 times higher during loading and unloading. The risk of industrial incidents caused by the hull is 9.50 times higher than those caused by fishing gear, 4.59 times higher than those caused by machinery, and 3.61 times higher than those caused by the caught fish. Among the types of industrial incidents, slips are the highest: 2.58 times higher than industrial incidents caused by being bump, 3.74 times higher than those caused by hit, and 3.94 times higher than those caused by imbalance and overexertion. For long liners, most industrial incidents are concentrated in diseases, with dental, musculoskeletal, skin, and respiratory diseases being the primary types of industrial incidents identified. This study aims to propose reduction measures for reducing the high-risk form of industrial incidents, specifically slips, and to present health management strategies for preventing diseases among fisher on overseas tuna fishing vessels. By addressing these aspects, this study seeks to contribute to the safety and sustainability of the overseas tuna fishing industry.

In this study, samples of sea anchor canopy cloth mainly used in Korean jigging fishing vessels were collected and tested for performance evaluation. The canopy cloth of sea anchor is a basic element of form composition that is known to have the greatest influence on anchor performance. In order to evaluate the performance of sea anchor canopy cloth, five types of samples were tested for new metric count, tensile strength, water vapour transmission rate and drying speed according to the national standard (KS), and some correlations were identified. As a result of the test, the new metric count of cloths was 335.5-443.4 denier in warp and 217-447.6 denier in weft, and the minimum tensile strength was 860 N in warp direction and 430 N in weft direction. The apparent number and tensile strength of cloth were proportional, the water vapour transmission rate of the sample was 206.8 g/m 2 h, and the drying speed was 90-100 min. This study partially confirmed the performance evaluation based on speculation by the standard test method, and further research is needed on the clear relationship between the research results and the performance of the sea anchor.

Fishery sea anchor is widely used for many fishing vessels. However, standardization of the dimension and terminology of the fishery sea anchor has not been achieved, reducing the reliability of the performance and safety of the fishery sea anchor. Therefore, this study researches the reality of usage of fishery sea anchor and then attempts to suggest the development direction of the standard draft as basic data. As a result of the survey on the reality of usage show that various terms were used for each part of the fishery sea anchor (including the incorrect form of non-standard words derived from Japanese) and that the production of this product in the fishery sea anchor market was concentrated on one specific manufacturer. In addition, the main specifications of the fishery sea anchor are set and manufactured based on conventional experience without standards. In the field, there was no standardized drawing for fishery sea anchor and users had low awareness of the main specifications of fishery sea anchor. Therefore, this study suggested the following regarding the fishery sea anchor: standard terms for each part including Korean and English names and standard drawing of sea anchor. It is hoped that this study will contribute to research for the standardization of fishery sea anchor, which will increase in reliability and lead to increased interest in standardization in the fishery field.

국내 콩에서 발생하는 세균병해인 불마름병, 들불병, 세균점무늬병, 세균갈색점무늬병의 다중 진단을 위한 PCR 방법을 요약하면 다음과 같다.1. 콩에 발생하는 각각의 세균들은 서로 다른 박테리오신(bacteriocin) 이나 파이토톡신(phytotoxin)을 생산하는데 이와 관련한 유전자를 목적으로 하여 진단프라이머를 설계하였다.2. 불마름병은 glycinecin A, 들불병은 tabtoxin, 세균점무늬병은 coronatine과 세균갈색점무늬병은 syringopeptin을 목적유전자로 하여 다중 진단프라이머 조합을 설계하였다.3. 1차 선발로 각각의 균주에 대한 단일 진단 프라이머를선발하였으며, 여기선 선발된 21개의 프라이머들을 조합하여 4종 다중진단프라이머 선발을 위한 2차 선발에 이용하였다. 최종적으로 280 bp의 불마름병, 355bp의 세균갈색점무늬병, 563 bp의 들불병과 815 bp의세균점무늬병으로 구성된 다중진단 프라이머 조합이개발되었다.4. 선발된 4종 다중 진단 프라이머 조합의 경우 다른 세균들과의 비특이적 반응이 있는지 확인하기 위한 3차선발을 거쳐 그 특이성을 검증하였다.

들깨는 전국 재배면적 28,000ha로 충북, 충남, 강원 지역이 주요 재배지역이다. 주로 간작, 후작용으로 재배되고 있으며, 특히 강원지역의 경우 옥수수 후작으로 재배되고 있으나, 적합 품종 및 재배법 연구가 미흡한 상태이다. 본 시험은 옥수수 후작 들깨 재배시 이식기에 따른 수량 및 주요성분인 지방, 지방산, 단백질을 비롯한 2차 대사산물의 주요성분 변이를 분석하고 비교하고자 수행하였다. 2009년 강원도 화천군 농가 포장에서 실시하였으 며, 시험재료로는 안유, 다유, 대유를 사용하였으며, 3엽기 묘를 6월 15일, 6월 30일, 7월 15일 각각 이식하였으 며, 들깨 표준재배법에 준하여 재배하였다. 그 결과로 이식기별 수량은 품종마다 조금씩 차이가 있었으나, 대체로 6월 15일이 가장 높았고, 다유가 전 시기별로 가장 수량이 높게 나타났으며, 수량구성요소인 분지수와 화방군수가 다른 품종에 비해 높게 나타난 결과로 판단된다. 지방 및 이차대사산물의 함량을 조사한 결과 안유의 아피제닌 함량을 제외하고 전반적으로 파종기가 늦어질수록 성분의 함량이 줄어드는 경향을 보였 으며, 파종기-성숙기의 생육일수가 길어질수록 기름함량 및 이차대사산물의 함량 또한 높아지는 것으로 판단 된다.
