This study aimed to quantitatively analyze the risk using data from 329 safety accidents that occurred in aquaculture fisheries management vessels over the recent five years (2018-2022). For quantitative risk analysis, the Bayesian network proposed by the International Maritime Organization (IMO) was used to analyze the risk level according to the fishing process and cause of safety accidents. Among the work processes, the fishing process was analyzed to have the highest risk, being 12.5 times that of the navigation, 2.7 times that of the maintenance, and 8.8 times that of the loading and unloading. Among the causes of accidents, the hull and working environment showed the highest risk, being 1.7 times that of fishing gear and equipment, 4.7 times that of machinery and equipment, and 9.4 times that of external environment. By quantitatively analyzing the safety accident risks for 64 combinations of these four work processes and four accident causes, this study provided fundamental data to reduce safety accidents occurring in aquaculture fisheries management vessels.

We analyzed work safety risk factors, which are likely to occur during fishing in gillnet fishing vessels using the written verdict of the Korea Maritime Safety Tribunal from 2016 to 2020, and considered work safety management. Of the total of 37 fatal accidents, three cases in the East Sea, six cases in the South Sea, and 28 cases in the West Sea were very frequent. The accident rate per vessel by sea area (%) was 0.08% in East Sea, 0.12% in South Sea, and 0.40% in the West Sea. Based on the East Sea, the number of fatal accidents was 1.6 times higher in the South Sea and 5.4 times higher in the West Sea. Six cases (16.2%) occurred during departure and preparation for fishing in the fishing process, and all other 31 cases (83.8%) occurred during fishing operation. In the order of accident types, 21 cases (56.8%) of being struck by object, eight cases (21.6%) of contact with machinery and six cases (16.2%) of falls from height were found to be fatal accidents in gillnet fishery. Human factors, such as fishers’ carelessness and negligent safety management by captain accounted for 27 cases (73.0%) of the main cause, and 35 cases (94.6%) of the secondary cause. In addition to human factors such as fisher’s carelessness and negligent safety management by captain, mechanical factors, environmental factors and management factors must be improved together to reduce human casualties. These results are expected to be utilized as basic data for reducing safety accidents during the work of fishers.

어선보험 및 어선원보험은 열악한 지위에 있는 어선소유자 및 어선원을 보호하기 위하여 어선원 및 어선 재해보상보험법에 따라 운영되는 정책보험이다. 선박충돌사고가 발생하면 어선소유자는 어선보험에서, 어선원은 어선원보험에서 먼저 보상을 받고 보험자인 수산업협동조합중앙회(이하 ‘수협중앙회’라고 한 다.)는 상대선 소유자 등에 대하여 구상을 하게 되는데, 이 경우 어선보험과 어선원보험의 특성으로 인해 다른 보험과 구별되는 여러 가지 문제점들이 야기된다. 어선보험 구상의 경우 수협중앙회의 구상권 청구에 대하여 상대선 소유자가 자신의 불가동 손실과 상계를 주장할 경우 타 선박의 불가동 손실을 보상 범위에 포함하지 않는 어선보험의 충돌배상약관과 모순되는 문제, 피보험자와의 관계에서「상법」제682조 제1항 단서에 따른 보험자 대위권 행사 범위 제한 문제, 일본과 중국 등 외국적 어선과의 충돌사고에서 이루어지는 양국 어업협회 혹은 수산회를 통한 배상협의에서 불가동 손실이 그 협의대상에서 배제되어 있는 문제 등이 제시될 수 있다. 한편 어선원보험 구상의 경우 어선원보험금 산정의 기준이 되는 임금과 손해배상에서 적용되는 임금이 상이한 문제, 손해배상소송에서 통계임금이 어선원의 실질적인 임금을 반영하지 못하는 문제, 보험금 지급시의 장해등급 평가와 소송상 신체감정의 차이에서 발생하는 문제, 어선원보험의 유족보상 수급자 인 유족 순위와 손해배상의 상속권자 순위가 다른 문제, 국민건강보험공단의 구상권과의 순위 문제 등 여러 가지 문제점이 존재한다. 어선보험 및 어선원보험과 그 구상에 대하여는 위와 같이 여러 문제가 다수 존재하고 있음에도 불구하고 논의가 많이 이루어지지 않았다. 그에 따라 법원 의 선례도 거의 없는 관계로 위에서 언급한 문제들 및 그 해결책에 대한 심도 있는 연구가 필요할 것이다.

A fisher means any person employed to provide his/her labor in a fishing vessel in exchange for a wage. There is no concept of a fisher in Seafarers Act. This act shall not apply to seafarers who are in service on board a fishing vessel the gross tonnage of which is less than 20 tons. However, of the total 63,112 fishing vessels, only 2,829 fishing vessels have a total tonnage of more than 20 tons. Fishermen engaged in fishing vessels with a gross tonnage of which is less than 20 tons are not guaranteed to be paid arrears through the Wage Claim Guarantee Fund for Seafarer (Article 56). In addition, fishermen working on a fishing vessel are excluded from the Wage claim Guarantee Act. The Labor Standards Act shall apply to fishermen engaged in fishing vessels with a gross tonnage of which is less than 20 tons. Fishermen and seafarers are at a higher risk of living security than regular workers. Guaranteeing the payment of wages is essential for fishermen to improve the life and employment stability. In order to guarantee fisher wage claims, the concept of a fisher in the Seafarers Act must be realized by sources such as the Wage Claim Guarantee Fund of Ministry of Oceans and Fisheries, step by step expansion of members in the wage claim guarantee fund for seafarers and interest for delayed payment of wages, etc.

The adjudication of Korean Maritime Safety Tribunal (KMST) was analyzed to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen’s occupational accidents of the National Federation of Fisheries Cooperative (NFFC) in stow net fishing vessel from 2015 to 2019. The personnel’s carelessness was the most common in 29 out of 33 accidents (87.9%), followed by 25 cases (75.8%) of inadequacy of instructions, 24 cases (72.7%) of inadequacy of education on hazard factor, 20 cases (60.6%) of no personal protection equipment, 18 cases (54.5%) of poor guard, 17 cases (51.5%) of inadequacy of work method, 16 cases (48.5%) of absence of emergency stop button, 14 cases (42.4%) of work practice of poor safety precautions that affected more than 40% of all accidents as accident causes. These causes had a strong influence on each other, and the ratio of accident causes is high. With this relationship, accidents can be prevented or the severity of human injury can be reduced if types of accident process can be estimated with a scenario, and the key points before the accident in the scenario are switched to safe points.

The questionnaire survey was carried out to collect basic data to identify the cause of the risk that did not appear in the current data provided by the fishermen’s occupational accidents of the National Federation of Fisheries Cooperative (NFFC) to the onsite specialist, such as a fishing master, chief engineer and fisher in stow net fishing vessel from June to July 2018. The results are as follows. A total of 134 cases were surveyed, including 53 cases in Yeosu, 44 cases in Mokpo, 30 cases in Boryeong and 7 cases in Gunsan. Approximately 60% of the respondents on board the stow net fishing vessel were more than 20 years old, and the boarding experience was seasoned and suitable for the respondents. In the 4M analysis by safety accident factor during fishing work, the mechanical factors included 51 cases (25.0%) of decrepit equipment or poor maintenance and 49 cases (24.0%) of systemic error of fishing equipment. The environmental factors exhibited 71 cases (33.5%) of poor communication by mixed manning of foreign fishermen and 63 cases (29.7%) of poor environment such as heavy weather etc. The human factors showed 78 cases (37.3%) of personnel’s carelessness and 45 cases (21.5%) of unskillfulness of operating net and haulers. The management factors exhibited 59 cases (32.1%) of work practice of poor safety precautions and 56 cases (30.4%) of inadequacy of education on hazard factor. The results are expected to contribute to the creation of a safe operating environment for stow net fishery, such as a fisher boarding a stow net fishing vessel, enabling the analysis of major causes of working safety accidents by cause.

Stow net fishery is one of the fishery with high fishing work accidents in southwestern sea of Korea. We conducted to serve as basic data for improving the healthy and safe working environment of fisher using risk assessment process (ISO45001) with fishermen’s occupational accidents of the National Federation of Fisheries Cooperative (NFFC) from 2016 to 2018. The average occurrence rate of victim in this fishery was 9.04%, 16.7 times more than such rate in all industries. In addition, the average fatality rate was found to have a very serious level management to 31.06‱, 27.7 times more than such rate in all industries. The safety hazards of stow net fishery was more likely to occur by other general industrial groups, with more severe consequences after the accident. According to 4M analysis, 58.6% of all accidents were caused by human factors, 24.0% by environmental factors, 16.0% by mechanical factors, and 1.5% by managerial factors, respectively. The occurrence frequency by accident type was the highest in 187 cases (32.2%) for struck by object, 158 cases (27.2%) for slipping, and 94 cases (16.2%) for being in contact with machinery. Severity is the highest for others such as diseases etc., in the order of being struck by object, being in contact with machinery, falling from above slipping, collapsing, bumping, and burning. Being struck by object, being in contact with machinery, and slipping are high-risk groups, falling from above others, bumping, and burning are medium-risk groups based on the risk assessment using the occurrence frequency and severity of accident. The obtained results are expected to contribute to the safe operation environment subsidy for fishing crews on the stow net fishing vessel.

The Fisher House, the first Korean Legation in the USA was located at 1513 O Street in Washington, D.C. This house was a three-story brick building with a height of 12.2m(8.84m up to the eaves) and a mansard roof. Facing the street, it is 7.32m (24 feet) wide and 23.6m(77.4 feet) depth. There is a long hallway after the entrance and a parlor with a grand fireplace next to it. This long hallway leads to a central hallway with another fireplace and a central staircase connecting the 2nd and 3rd floors. After the stairs a dining room is with a fireplace in the middle, which then leads to a pantry for dishes and the kitchen. It can also be argued that The Fisher House was the first Western-style residence for Koreans who were officially dispatched from the government. On the other hand, when living in The Fisher House, Park Jung-yang, who was sent on the three premises of the Yeonjak, directly experienced how the United States sought independence from the U.K. through the Declaration of Independence, Mount Vernon, the Washington monument, the Arlington National Cemetery, and battlefields. Even though he was summoned back to Korea by China in less than a year, Park Jung-yang actively supported the independence movement when he became acting prime minister in 1896. In this regard, The Fisher House arguably is the birthplace of Korea’s independence movement.

The coastal composite fishery has the highest rate of around 30.0% in registered fishing vessels of Korea for the last three years. The risk analysis for the fisher’s safety of coastal composite fishing vessels was conducted to serve as a basic data for improving the healthy and safe working environment of fisher using fisher’s occupational accidents of the national federation of fisheries cooperatives (NFFC) from 2016 to 2018 (n = 1,105). As a result, the occupational accident occurrence rate of coastal composite fishery was 3.76% in all industries, 7.8 times the rate of that. In addition, death and missing rate was found to have a serious level management to 10.10‱. Among the accidents, 76.0% occurred at sea. The slipping, others and contact with machinery or fishing gear occurred more frequently in order in the frequency of accident occurrence pattern. In the risk assessment using frequency and severity, slipping, contact with machinery and others showed high risk during fishing. The results are expected to contribute to identification and assessment of safety hazard occurred in coastal composite fishing vessels.

This paper presents a new feature representation method, named two- dimensional orthogonalized Fisher discriminant analysis(2D-OFD). The method adopts the 2D-LDA and orthogonalization of Fisher vector. It produces the small size scatter matrix than 1D method. Therefore it can evaluate the scatter matrix accurately. In addition, it is not suffered from small sample size problem. The orthogonalization eliminates the linear dependences among Fisher's discriminant vectors. As a result, it promotes the discriminant capability of the 2D-LDA. The proposed method is tested on the ORL face image database. We test our method 10 times. For each experiment, five training images are randomly chosen each person and the other five images are used for testing. The test show that the average recognition rate is 96.2%. When the image is downsampled to 28x23 matrix to reduce the computational complexity, the average recognition rate is 95.9%.

Recently, IPTV population is growing by leaps and bounds. and We performed FGI(Focus Group Interview) with various experts related to agriculture field to establish Agriculture and Fisheries special channel. this growth has social background that is change of paradigm caused by the convergence of broadcasting, demand for Agriculture and Fisheries special channel using new media thanks to interests in Wellbeing, Green food. so we think that we need to consider the way to establish Agriculture and Fisheries special channel and its validity from all angles. that is why we are having a heated discussion with Agriculture and Fisheries marketing experts, farmer, fisher(Korean Cyber Farmer Association), broadcasting experts. Concretely, government budget is needed to establish Agriculture and Fisheries special channel, so we are just about to examine its validity and find business model. to make this discussion detailed, we made 4 subjects. First, Do we need agro-fishery products distribution channel using media? Second, After establishing of Agriculture and Fisheries special channel, how many demands will occur? Third, Should we make Agriculture and Fisheries special channel public channel? Fourth, What would be profit model of Agriculture and Fisheries special channel?

Fisher-Tropsch synthesis for the production of hydrocarbon from syngas was investigated on 20% cobalt-based catalysts (20% Co/HSA, 20% Co/Si-MMS), which were prepared by home-made supports with high surface areas such as high surface alumina (HSA) and silica mesopores molecular sieve (Si-MMS). In the gas phase reaction by syngas only, 20% Co/Si-MMS catalyst was shown in higher CO conversion and lower carbon dioxide formation than 20% Co/HSA, whereas the olefin selectivity was higher in 20% Co/HSA than in 20% Co/Si-MMS. In the effect of n-hexane added in syngas, the selectivities of C5+ and olefin were increased by comparing the supercritical phase reaction with the gas phase reaction in addition to reduce unexpected methane and carbon dioxide.

This paper reviews nonparametric statistics by Neyman-Pearson test and Fisher test. Nonparametric statistics deal with the small sample with distribution-free assumption in multi-product and small-volume production. Two tests for various nonparametric statistic methods such as sign test, Wilcoxon test, Mann-Whitney test, Kruskal-Wallis test, Mood test, Friedman test and run test are also presented with the steps for testing hypotheses and test of significance.

We analyze the dependence of the mass-to-light ratio of spiral galaxies on the present star formation rate (SFR), and find that galaxies with high present star formation rates have low mass-to-light ratios, presumably as a result of the enhanced luminosity. On this basis we argue that variations in the stellar content of galaxies result in a major source of intrinsic scatter in the Tully-Fisher relation (TF relation). Ideally one should use a 'population-corrected' luminosity. We have also analyzed the relation between the (maximum) luminous mass and rotational velocity, and find it to have a small scatter. We therefore propose that the physical basis of the Tully-Fisher relation lies in a relationship between the luminous mass and rotational velocity, in combination with a 'well-behaved' relation between luminous and dark matter. This implies that the Tully-Fisher relation is a combination of two independent relations: (i) a relation between luminosity and (luminous) mass, based mainly on the star formation history in galaxies, and (ii) a relation between mass and rotation velocity, which is the outcome of the process of galaxy formation. In addition to a 'population-corrected' Tully-Fisher relation, one may also use the relation between mass and luminosity, and the relation between luminous mass and rotation velocity as distance estimators.

We analyse the results of mass models derived from the HI rotation! curves of spiral galaxies and find that the slope of the luminous mass-circular velocity relation is close to 4. The luminous mass-circular velocity relation with a slope of about 4 can be explained by an anti-correlation between the mass surface density of luminous matter and the mass ratio of the dark and luminous components. We also argue that the conspiracy between luminous and dark matter exists in a local sense (producing a flat or smooth rotation curve) and in a global sense (affecting the mass ratio of the dark and luminous matter), maintaining the luminous mass-circular velocity relation with a slope of about 4. We therefore propose that the physical basis of the Tully-Fisher relation lies in the luminous mass-circular velocity relation. While the slope of the luminous mass-circular velocity relation is fairly well defined regardless of the dark matter contribution, the zero-point of the relation is still to be determined. The determination of the slope of the Tully-Fisher relation needs one more step: the mean trend of the luminosity-luminous mass relation determines the overall shape (slope) of the Tully-Fisher relation. The key parameter needed to determine the zero-point of the luminous mass-circular velocity relation and the slope of the Tully-Fisher relation obviously is the luminous mass-to-light ratio.

Purpose - This paper aims to verify whether the Fisher effect and the international Fisher effect are significant between China and South Korea in the long and short run, respectively. Research design, data, and methodology - The annual and monthly data, respectively, are employed to conduct an empirical estimation under the fully modified ordinary least squares(FMOLS). The nominal interest rate is treated as an independent variable. The inflation rate is treated as a dependent variable. Results - The results exhibit whenever in the long or short run, the Fisher effect exists in China and South Korea. However, the Fisher effect in South Korea is more significant than that of in China. Meanwhile, an empirical analysis is also preformed to investigate the long-run and the short-run international Fisher effect between China and South Korea. The deviation from the equilibrium relationship is that the commodity market and the Financial market have started to integrate in China. But China’s integrated level proved to be relatively lower. Conclusions - To exploit that the Fisher effect and the international Fisher effect hold between China and South Korea can help both countries deal with the sufferings from integration of the commodity market and the financial market.

본 연구는 한국 제천에서 재배된 감초(Glycyrrhiza uralensis Fisher, G. uralensis)를 대상으로 추출 조건(85% 에탄올, 추출 온도 및 시간)별로 추출한 추출물에 대하여 항산화 활성 및 항균 활성을 측정하고 이로 부터 최적의 추출 조건을 선정하여 감초 추출물을 화장품 원료로 개발하기 위한 제조 공정에 활용하고자 하였다. 실험에 사용한 시료는, 각 추출 조건에서 얻어진 추출물을 농축하여 분말로 한 시료(시료-1)와 추출물을 농축 하지 않고 추출물 원액을 그대로 사용한 시료(시료-2)이다. 항산화 활성은 라디칼 소거활성, 총항산화능, 활성 산소로 유도된 세포손상에서 세포보호효과를 측정하였다. 항균 활성은 피부 상재균에 대한 최소저해농도를 측정 하였다. 1,1,-Diphenyl-2-picrylhydrazyl를 이용한 라디칼 소거활성에서, 시료-1은 100 μg/mL에서 추출시 간이 6 h일 때가 12 h일 때보다 약 10% 정도 더 큰 라디칼 소거활성을 나타냈다. 반면에 시료-2의 라디칼 소거활성은 추출 시간에 따른 유의적 차이를 나타내지 않았다. 한편 동일 온도에서 12 h 추출한 추출물의 수율 은 6 h 추출한 경우의 수율보다 2.6배 더 컸다. 하지만 총 플라보노이드 함량은 1.1배 정도 더 크게 나타났다. 따라서 추출 시간이 길어도 총플라보노이드 함량은 거의 증가하지 않았음을 보여준다. 추출 조건별 감초 추출물 의 라디칼 소거활성, 총항산화능 및 세포보호효과가 추출물의 수율을 반영한 것이 아니라 추출물 중에 함유된 총플라보노이드 함량에 의존함을 나타내고 있다. 피부 상재균에 대한 항균 활성은 추출 조건별 동일 농도(시료 -1)에서 측정했을 때, 세 균주(S. aureus, B. subtilis, P. acnes)에 대해 25 및 40 ℃에서 추출된 감초추출물 (156 μg/mL)은 methyl paraben (2,500 μg/mL)보다 약 16배 정도로 매우 큰 항균 활성을 나타냈다. 결론적 으로 항산화 활성 및 항균 활성이 큰 감초 추출물의 최적 추출 조건은 85% 에탄올로 40 ℃에서 6 h 추출한 추출물이 최적임을 확인할 수 있었다. 본 연구 결과, 화장품에 항산화 활성 및 항균 활성이 큰 감초 추출물을 원료화하기 위해서는 추출 조건별 추출물의 수율, 활성 성분의 수율, 추출물의 농도별 활성 평가와 추출 수율이 반영된 추출물 원액 자체의 활성을 종합 평가해서 추출 조건을 선정해서 원료의 제조 공정에 반영하는 것이 중요함을 시사한다.
