The purpose of this study is to analyze the structure, status and economic ripple effects of the fisheries processing industry in Korea using interindustry analysis. Five input-output tables published over the past twenty years have been reclassified with a focus on the fisheries processing sector. Through these multi-period tables, we analyzed changes in the inducing effects in production, value added and employment as well as the backward-forward linkage effects. As a result of the analysis, it was found that the industrial scale of the fisheries processing industry is very small compared to other food manufacturing industries. The backward linkage effect of the fisheries processing industry was greater than that of other industries, but the forward linkage effect was rather low. This means that the fisheries processing industry can be greatly affected by industrial depression of the downstream industries such as fishery and aquaculture. Production and employment-inducing effects of the fisheries processing industry have shown a decreasing trend in recent years. This reflects the reality that intermediate inputs are gradually being replaced by imports from domestic production due to the expansion of market opening and the depletion of fishery resource. In the future, it is necessary to prepare a strategy to increase the value-added productivity of the fisheries processing sector and foster it as an export industry.

한반도 남해안 지역의 여름철 대기 안정도 특성을 분석함으로써, 한반도 특성에 맞는 강수 예측을 위한 대기 안정도 지수의 정량적인 임계값을 도출하고자 하였다. 보성 표준기상관측소에서 관측한 2019년도 여름철 라디오존데 집중관측자료를 분석에 사용하였으며, 총 관측자료는 243개이다. 강수 유무 및 중규모 대기 현상에 대한 대기 안정도를 분석하기 위해서, 대류가용잠재에너지(Convective Available Potential Energy, CAPE)와 폭풍지수(Storm Relative Helicity, SRH)를 비교하였으며 특히 SRH 분석은 고도별로 총 4개의 층으로(0-1, 0-3, 0-6, 0-10 km) 세분화하였다. 강수 유무에 따른 분석은 강수가 없는 경우, 강수발생 전 12시간, 강수 발생 시로 구분하여 수행하였다. 그 결과, 2019년도 보성에서 발생한 여름철 강수 예측에는 CAPE 보다 SRH가 더 적합하며 0-6 km SRH가 약한 토네이도가 발생 가능한 기준과 같은 150 m 2 s−2 이상일 경우 강수가 발생한 것으로 분석 된다. 또한, 장마와 태풍 기간의 대기 안정도를 분석한 결과를 보면, 일반적으로 SRH는 대기 깊이가 두꺼워질수록 값이 커지는데 반해서 0-10 km SRH 평균값 보다 0-6 km 의 SRH 값이 더 크게 나타났다. 따라서, 2019년도 보성에서 발생한 태풍에 의한 강수를 판별하는 데는 0-6 km 의 SRH 값이 더 효과적이라고 할 수 있다.

This study was conducted to investigate the intake status of beverages and water in Korean adults using data from the 8th National Health and Nutrition Examination Survey. The ‘total water’ intake was 2,250.6 g for men and 1,871.2 g for women. Men and women consumed an average of 314.9 g of ‘total beverages’, of which ‘coffee’ was the largest at 107.5 g, followed by ‘others’(65.4 g), ‘milk’ (44.8 g), ‘soda’ (44.1 g), ‘teas’ (20.9 g), and ‘fruits and vegetables’ (18.5 g). The intake of ’plain water’ was 1,059.9 g, and the intake of ’water from food’ consumed was 547.3 g. The ‘total water’ intake decreased with increasing age in males and females (p<0.001). Both men and women showed a tendency toward increased ‘total water’ intake as income levels increased. ‘Plain water’ intake accounted for 51.4% of the ‘total water’ intake in males and females. The intake of all nutrients significantly increased from the Q1 group to the Q4 group by quartile ranges of total water intake. The results of this study showed that the intake of healthy water should be considered, and care and educational programs are needed, especially for older people, to ensure adequate water intake.

This study discusses the representation of women and the use of discriminatory language expressions regarding them in movies. This study analyzed female characters and the language expressions used in relation to these female characters in the films between 2014 and 2019. Considering features of each character, the following types of discrimination were observed: “treating women as sexual objects” and “subordinating wife to husband” on the subject of right and violence, “treating women as men’s subordinates” for labor and in positions of leaderships, “excluding women” in terms of race and disabilities, “restricting women to gender-specific roles such as housewives” in motherhood and image of women, and “treating women’s behavior or personality differently’ in abilities and occupations. In the result of discriminatory language expressions, “degrading of women” was most frequently observed. And “treating women’s behavior or personality differently” was observed in few movies, exhibiting the lowest frequency. “Treating women as subordinates to men” and “excluding women” were expressions of discrimination in public spheres against social advancement, and “restricting women to gender-specific roles such as housewives” and “subordinating wife to husband” can be considered expressions of patriarchy.

In this study, data from the 7th (2016~2018) and 8th (2019) Korea National Health and Nutrition Examination Surveys were used, which included 5,325 subjects. Health behavior, dietary and nutrient intake status, physical measurement and biochemical characteristics, and risk factors for elderly related chronic diseases were classified and analyzed according to the changing composition of single households and other households in the current society. As a result, the ratio of current smokers and drinkers in young adult single households, walking less than 30 minutes per day, subjective health status was poor, breakfast rate less than three times per week, eating out frequency more than once a day, lipid intake ratio to total calories, saturation fatty acid intake were significantly higher. In addition, waist circumference, and diastolic blood pressure were significantly higher. However, dietary fiber intake level was significantly lower. The results for hypertension, which is the representative chronic disease that causes old age-related chronic diseases, were significantly higher in single households (ORs=1.400 (95% CI: 1.095, 1.791), p=0.007). Although young adults may not have showed particularly serious health problems yet, education is believed as important to recognize and prevent age-related disease risk factors.

Since the first detection of African swine fever (ASF)-infected wild boar in October 2019, the ASF virus has been circulating among wild boars in the Republic of Korea. The priority for ASF control is to understand the epidemic situation correctly. The basic reproduction number (R0) can be used to describe the contagious disease epidemic situation since it can assess the contagiousness of infectious agents by presenting the average number of new cases generated by an infected case. The current study estimated R0 for the 2019/20 ASF epidemics in wild boars in the Republic of Korea using the reported number of ASF cases and a serial interval of the ASF virus. The estimated mean R0 was 2.10 (range: 0.06 – 10.24) for the 2019/20 ASF epidemics, 2.94 (range: 0.43 – 9.89) for the 2019 ASF epidemics, and 2.00 (range: 0.06 – 11.10) for the 2020 ASF epidemics. In addition, the estimated mean R0 was 3.82 (range: 1.16 – 8.78) in winter, 1.39 (range: 0.16 – 6.30) in spring, 4.82 (range: 0.26 – 17.08) in summer, and 2.21 (range: 0.51 – 5.86) in fall. Even though the Korean government has applied ASF control measures, including hunting or fencing, the ASF epidemic situation in wild boars has intensified. For ASF control in wild boars, tailor-made hunting, wild boar management, or active searching for carcasses are required to reduce the ASF virus. For ASF prevention in domestic pigs, no contact between wild boars and domestic pigs and a biosecurity plan by veterinarians are needed to decrease the risk of ASF virus transmission from wild boars to domestic pigs.

This study employed a bibliometric method to visualize the evolution of corpus-based discourse studies between 1995 and 2019, with a total of 2,174 English-language documents and their 83,184 references collected from Scopus, the Social Science Citation Index, and the Arts & Humanities Citation Index. Co-citation analysis of the predominant authors, references, and publication sources disclosed that the field has expanded over the past 25 years from primary pattern analysis of descriptive and functional grammar to principal investigations of interdisciplinary issues, some of which are central to pragmatics and sociolinguistics. This shift of research focus is also evidenced by keyword analysis. Scholars have been progressively more fascinated by such social issues as news discourse, business discourse, gender and language, and identity. Some emerging topics like social media, media discourse, legal discourse, and the metadiscourse interpersonal model may represent research hotspots and trends in this area. Bibliometric approaches play an important role in providing hands-on evidence-based comparisons and visualizations of previous research outputs using different time bands.

Feral cats are widely considered to be leading the potential impacts on public health. This study aimed to provide estimates of vital data for feral cats relating Trap-Neuter-Return (TNR) to establish strategies effectively to manage feral cats in Pyeongtaek. Thus, this study focused on estimating feral cat population in Pyeongtaek and conducted a comparative analysis of the data for feral cats in Seoul (2013). The number of feral cats was estimated from 23,069 to 26,655 in Pyeongtaek, 2019. In relation to human population, when comparing the number of feral cats of Pyeongtaek and Seoul, it ranged from 4.57% to 5.28%, and from 1.97% to 2.55% respectively. This showed that Pyeongtaek was higher than Seoul. Fewer kittens were found in high-density areas, which the TNR project is believed to be generally effective in controlling the number of feral cats. In conclusion, in urban and rural complexes such as Pyeongtaek City, the number of feral cats compared to the population was higher than that of Seoul City, and the TNR program is believed to be somewhat effective in controlling the number of feral cats. When implementing TNR, it is necessary periodically to investigate the population and reflect them in policymaking.

화상병균(Erwinia amylovora)에 의해 발생하는 과수 화상병은 주로 사과, 배 등의 장미과 식물에서 발병한다. 과수 화상병은 국내에서 금지 병원균으로 지정되어 있으며, 2015년 경기도 안성의 배과수원에서 최초 발견되었다. 그러나, 현재까지 근본적인 방제약제가 없는 상황으로 발생지는 매몰이 최선의 방법으로 여겨진다. 따라서 본 연구에서는 2019년을 기준으로 충북지역의 과수 화상병 발생 원인 분석을 통하여 발생 경로 차단을 위한 역학조사를 실시하였다. 1. 충주시 등 3개 시군의 전체 221농가 141ha에서 과수 화상병이 발생하였으며, 세부적인 연도별 발생현황은 2015년(2농가 1ha), 2018년(74농가 51.5ha), 2019년(145농가 88.9ha) 로 나타났다. 2. 과수 화상병의 발생시기는 주로 5월부터 8월 사이로 나타났으며, 특히 6월(73.8%)이 가장 많이 발생하였으며, 7월 (17.2%), 5월(7.6%), 8월(1.4%)순으로 나타났다. 3. 과수 화상병 발생 의심 신고 후 확진 매몰까지 소요기간은 11.9일이었고, 발생에서 매몰까지의 기간은 최단 5일에서 최장 19일로 조사되었다. 4. 병원균의 최초 발생지로부터의 확산 거리는 평균 21 km로 나타났으며 가장 먼거리는 음성군 비산면으로 34 km였다.

Rabies is a zoonotic disease that is caused by rabies virus and transmitted only in mammals. Domestic dogs are the most common reservoir of the virus, which is associated with more than 99% human deaths caused by dog-mediated rabies in the world. Rabies is one of the most fatal diseases, but it is fully preventable in animals by vaccination. Serological test of rabies virus antibody for samples collected from dogs and cats in Seoul during 2017–2019 was carried out in this study. To investigate antibody seroprevalence of rabies virus for dogs and cats, 2,769 serum samples were taken from 2,408 dogs and 361 cats in various regions of Seoul during 2017– 2019. Antibodies to rabies virus were detected by an indirect ELISA. Of 2,769 tested animal sera, 934 (33.7%) were positive; 886 (36.8%) of 2408 dogs and 48 (13.3%) of 361 cats. Of 990 companion animals, 547 (55.3%) was positive and 387 (21.8%) of 1779 stray animals was positive. These results indicate that antibody seroprevalence to rabies virus is still not enough to prevent rabies and rabies vaccination is required to enhance the antibody seroprevalence for rabies. To improve the situation, much public awareness and policy is needed to prevent the rabies. In addition, reducing stray animals and keeping companion animals from contact with wild animals are indispensable for the prevention of rabies.
