We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.

This study investigated the inactivation effect of intense pulsed light (IPL) on various packaging films. The UV-C transmittance irradiance varied depending on the packaging materials, with the control group having an irradiance of 3.959 W/m2. For the thinnest layer of 30 mm, polypropylene (PP) had an irradiance of 3.258 W/m2, polyethylene (PE) had an irradiance of 3.193 W/ m2, and oriented polypropylene (OPP) had an irradiance of 3.200 W/m2. In contrast, polyethylene terephthalate (PET) exhibited a significantly lower irradiance of only 0.065 W/m2 for its thinnest film thickness of 100 mm. The light transmittance of the packaging materials was similar, with values of 91.3%, 89.7%, and 89.5% for PP, PE, and OPP, respectively. In contrast, PET exhibited a significantly lower light transmittance of 1.8% compared to the other packaging materials. These findings have practical implications for the food packaging industry. According to the packaging film material, the sterilization effects showed that the E. coli sterilization effect of PP was the highest, followed by PE and OPP, which were similarly effective. At the same time, PET exhibited the lowest sterilization effect. For PP film with a thickness of 30 mm, a 6.2 log reduction in the E. coli population was observed after 20 s of IPL treatment. Ultimately, inactivation was achieved after 60 seconds. Both PE and OPP films, which had a thickness of 30 mm, showed a 5.9 log reduction in E. coli after 30 s of IPL treatment, followed by complete inactivation after 60 s. The inactivation rate for PP, PE, and OPP films showed minimal variation regardless of thickness, although it gradually decreased with increasing thickness. For PET, achieving a 1 log reduction in E. coli required 180 s of IPL treatment at 100 mm thickness and 210 s at 120 mm thickness, indicating the influence of film thickness on inactivation rate. Even after 300 s of IPL treatment, the inactivation effect for PET remained around 1.5 log, the lowest among all packaging film materials.

본 연구의 목적은 도시 맥락적 관점에서 공연공간이 갖는 공공적 특성을 고찰하고 분석함으로써 추후 공연공간을 계획함에 공공성 구현을 위한 기초자료 역할과 방향을 제시하고 자 하였다. 문헌 고찰 및 선행연구, 사례조사를 통해 건축적 공공성 분석을 통해 공연공간의 공공성 분석항목을 도출하고, 도출된 공공성 요소를 토대로 사례별 공연공간의 공공적 특성을 분석하였다. 연구결과 현대사회의 변화에 따라 공연공간의 기능과 역할이 확대되고 다양해지고 있으며, 공연장을 지역 이나 도시의 커뮤니티 시설로 개방하려는 시도가 많아지고 있다는 것을 알 수 있었다. 그리고 상 업 및 편의시설 등, 다른 기능과 복합하여 이용자나 시민들에게 개방하여 접근이 쉬운 공간으로 변화하고 있음을 알 수 있었다. 본 연구를 종합해 보면 앞으로 국내의 도심 공연공간을 계획할 때 고려 요소로써 시설의 기능 다변화와 도시적 관계에 대한 고려가 중요하게 고려되어야 하겠다. 추후 연구에서는 범위를 확대하여 광범위한 국내외 사례분석과 다양한 관점에 따른 공간 분석을 통해 더 깊이 있는 연구가 필요하다고 판단된다.

에어브러시는 실용적이고 다양한 표현이 가능하므로 산업 각 분야에서 활용하고 있으며 특히 바디페인팅 아티스트에게도 필수적인 도구로 활용되고 있다. 에어브러시는 정교한 색상, 형태, 그라데이션 표현이 가능하며, 작업 시간이 단축되는 장점이 있어 바디페인팅 분야에서도 그 활용 영역이 점차 확대되 고 있다. 최근 국제적으로 인정받고 있는 월드 바디페인팅 페스티벌의 에어브러시 전용 카테고리 수상 작 품을 중심으로 디자인 구도, 색채 기획 및 배색과 표현기법을 분석하여 에어브러시 바디페인팅 작품의 최 신 디자인 경향을 제시하고자 하였다. 그 결과는 다음과 같다. 첫째, 디자인 구도에 있어서 주로 강조 (emphasis)와 균형(balance)의 원리를 사용하여 상반신의 정중앙에서 메인 이미지를 강조하고 하반신에서 는 좌, 우 대칭으로 균형이 잡힌 구도가 주요한 디자인으로 분석되었다. 둘째, 색채 기획 및 배색으로는 주 목성을 높일 수 있는 대비 배색의 활용이 주요하게 활용되었으며 셋째, 주요 수상 작품 모두 스텐실과 그라 데이션 기법을 활용하여 형태의 정확성과 입체감을 표현하였다. 이상의 분석 결과를 토대로 바디페인팅 디 자인을 기획하고 에어브러시를 활용하여 작품을 완성하였다. 이러한 작품 제작을 통해 에어브러시 바디페 인팅의 예술적 활용을 대중화하고 국내 에어브러시 바디페인팅 작품 연구에 도움이 되고자 한다.

The fatty acid composition and free amino acid content of domestic soybean cultivars were analyzed to confirm the quality characteristics of protein and fat contained in soybeans. The saturated fatty acid content of soybeans included palmitic acid at 9.47~11.15%, followed by stearic acid and myristic acid. The total saturated fatty acid content in soybeans was 12.56~14.34%, with Taekwang having the lowest content, followed by Daewon, Seonyu, Cheonga, and Jinpung. The linoleic acid content, an unsaturated fatty acid, was 45.69~58.17%, with Taekwang showing the lowest composition and Jinpung showing the highest composition. Next was oleic acid at 14.69~33.86%. Jinpung had the highest linoleic acid composition, had the lowest and Taekwang which had the least linoleic acid, had the highest. The unsaturated fatty acid content was in the order of linolenic acid, eicosatrienoic acid, eicosadienoic acid, and eicosapentaenoic acid. The total free amino acid content was 217.28~456.66 mg%, with Daewon showing the highest free amino acid content, followed by Seonyu, Taekwang, Cheonga, and Jinpung. The free amino acid content varied depending on the cultivars, but in general, the free amino acids in the soybeans used in the experiment showed higher aspartic acid, glutamic acid, and proline contents than other amino acids.
