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.

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.

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.

본 논문은 한·중·일 고전 문학 속에 등장하는 음식을 만드는 여성들의 모습을 살 펴보고자 하였다. 여성이 음식을 만드는 행위는 사랑과 정성의 실천이자, 누군가를 치유하는 수단이 되기도 하였다. 그리고 이러한 여성들의 음식 만드는 행위는 신을 감동하게 하여 복을 받거나 기적을 이루는 통로가 되기도 하였다. 한편 여성이 어떤 음식을 만들고 먹는가에 따라 자신의 전통적 신분과 사회적 지위가 드러나기도 하였 으며, 일부 낭만과 운치를 아는 여성들은 음식을 만드는 행위를 자연과 조화를 이루 는 예술, 새로운 창조의 경지로까지 승화시키기도 하였다. 마지막으로 봉건적 가부장 사회에서 여성이 음식을 만드는 행위는 단순히 음식을 만든다는 것을 넘어 현모양처 의 기준이었고, 여성의 정체성을 보여주는 척도가 되거나, 여성존재의 이유가 되기도 하였다. 이처럼 한·중·일 고전문학 작품 속에서 여성들이 만든 음식은 사랑하는 가족 을 먹여 살리고, 공동체와 사회를 키워냈으며, 자신을 치유하기도 하며, 죽은 이에게 는 최고의 봉양이며, 신에게 헌신으로 바치는 고귀한 제물이었다. 인간은 누구나 이 세상에 태어나서 엄마의 가슴에 안겨 먹는 젖으로부터, 사후 귀신이 되어 먹는 제사 음식에 이르는 기나긴 인생의 여정을 어머니, 아내, 그리고 딸과 며느리가 만든 음식 을 먹으며, 그녀들의 손을 잡고 함께 걸어갔던 것이었다.

꽃노랑총채벌레(Frankliniella occidentalis)와 오이총채벌레(Thrips palmi)는 경제적으로 오이의 중요한 해충이며 이들의 방제를 위해 사용 되는 화학약제는 효과적일 수 있으나 생식용으로 소비되는 오이에서 자주 사용하는 것은 바람직하지 않다. 따라서, 이들의 방제를 위해 화학농약 을 대체할 수 있는 천적인 미끌애꽃노린재(Orius laevigatus)의 방제효율을 증대시킬 수 있는 방법으로 미끌애꽃노린재의 천적유지식물을 선발하 였다. 실험실 조건에서 4가지 식물종에 대한 미끌애꽃노린재 부화율, 출현율, 생존률, 생식력을 조사하였고 오이 재배시설 내에서 선발된 2종의 천적유지식물에 대하여 미끌애꽃노린재 밀도를 조사하였다. 미끌애꽃노린재 알 부화율은 채송화가 92%로 가장 높았고 출현율은 바질이 81.4% 로 가장 높았으며, 생존률은 채송화와 바질이 각각 70.8%와 69.1%로 통계적 차이를 보이지 않았다. 미끌애꽃노린재 생식력과 산란기간은 모두 채송화가 각각 209.8개와 20.2일로 가장 좋았고 바질은 각각 160.2개와 15.8일이었다. 식물체 꽃의 개화시기는 화밀을 대체먹이로 하는 미끌애 꽃노린재의 생존에 중요한 요소이기 때문에 채송화와 바질의 개화시기를 조사한 결과 채송화는 7월에서 10월 개화하는 반면 바질은 4월부터 9월 까지 개화하였다. 시설 오이에 미끌애꽃노린재의 천적유지식물로 바질과 채송화를 투입하고 미끌애꽃노린재 밀도를 조사한 결과 바질이 투입된 곳에서 밀도가 높게 조사된 반면 채송화를 투입한 곳에서는 거의 보이지 않았다. 따라서, 바질은 미끌애꽃노린재의 천적유지식물로서 잠재적 가 치가 가장 높았으며 총채벌레 방제를 위해 미끌애꽃노린재를 이용할 경우 바질을 천적유지식물로 동시에 사용한다면 미끌애꽃노린재의 생물적 방제효과에 대한 효력을 증대시킬 수 있을 것으로 기대된다.

This study investigated associations between healthy dietary practices and the odds of prediabetes among Korean adolescents. The data of 1,624 adolescents aged 12 to 18 who participated in the 2017-2021 Korea National Health and Nutrition Examination Survey were analyzed. Healthy dietary practices were defined according to Health Plan 2030 criteria, and prediabetes was defined as a fasting blood glucose level of 100-125 mg/dL. After controlling for confounders, adjusting odds ratios and 95% confidence intervals (CIs) for prediabetes were determined for different healthy dietary practices using multivariable logistic regression analysis. Compared with adolescents who engaged in healthy dietary practices, those who did not had a 1.63-fold (95% CI: 1.12-2.37) higher odds of prediabetes. In addition, adolescents who did not consume ≥500 g of fruit and vegetables daily and those who refrained from reading nutritional fact labels, which are both subindicators of healthy dietary practices, had a 1.66 (95% CI: 1.05-2.62) and 1.58-fold (95% CI: 1.06-2.37) higher odds of prediabetes, respectively, than those who did. Increasing the proportion of adolescents engaging in healthy dietary practices, such as consuming ≥500 g of fruit and vegetables daily and reading nutritional fact labels when selecting food, is imperative.

In this study, we estimated the distribution density of giant jellyfish in coastal waters of Korea in 2023 and compared the occurrence of giant jellyfish over four years. In May, the giant jellyfish were mainly distributed in the waters of the Yangtze River outflow, and in July, they were highly distributed in the west of Jeju Island and near the south coast of Korea. In addition, when comparing the distribution densities of giant jellyfish in Korea over four years, both acoustic and sighting surveys showed that the highest density of jellyfish occurred in 2021.

To produce super sweet corn sikhye, substituted for sweetener, the ratio of rice and super sweet corn was adjusted and processed with complex enzymes during saccharification, and their physicochemical and sensory properties were analyzed. The soluble solid content of the control and Corn-5 showed significantly high content at 13.50 °Brix, and the reducing sugar content of Corn-5 showed the highest content at 9.45%. The control showed the lowest free sugar content among all the experimental groups, excluding maltose content. In the enzyme-treated corn sikhye group, as the amount of super sweet corn increased, the content of sucrose decreased and the contents of glucose and fructose increased. The content of ascorbic acid and polyphenol compounds increased as the amount of super sweet corn increased. DPPH and ABTS radical scavenging abilities increased with increasing ratio of super sweet corn and enzyme treatment compared to the control. In the case of sensory evaluation, Corn-3, which substituted 30% of super sweet corn for rice and treated with enzymes, showed higher evaluations in taste, sweetness, and overall preference than those of the control.

This study examined the power consumption of angling boats during entry, departure, and fishing operations using a black box-type storage device. Through this analysis, it determined the energy consumption and carbon emissions of small fishing boats used for catching the largehead hairtail. The energy consumption and carbon emissions were calculated using formulas provided by the Korea Energy Agency, which incorporated updated emission coefficients from 2022. The findings revealed that the average power consumption of small fishing boats for the largehead hairtail was 546.3 kWh, with a total energy consumption of 0.1164 TOE and carbon emissions of 24.057 CO2. The average energy consumption was calculated at 0.0006 TOE per kilogram, and the carbon emissions were determined to be 0.135 CO2/kg.
