배지윤,서연희,오세욱 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.8

Polyphenols are secondary metabolites produced in higher plants. They are known to possess various functional properties in the human body. Polyphenols also exhibit antibacterial activities against foodborne pathogens. Their antibacterial mechanism is based on inhibiting bacterial biofilm formation or inactivating enzymes. Food-derived polyphenols with such antibacterial activity are natural preservatives and can be used as an alternative to synthetic preservatives that can cause side effects, such as allergies, asthma, skin irritation, and cancer. Studies have reported that polyphenols have positive effects, such as decreasing harmful bacteria and increasing beneficial bacteria in the human gut microbiota. Polyphenols can also be used as natural antibacterial agents in food packaging system in the form of emitting sachets, absorbent pads, and edible coatings. We summarized the antibacterial activities, mechanisms and applications of polyphenols as antibacterial agents against foodborne bacteria.

Background We investigated cardiovascular disease (CVD), risk factors for CVD, and applicability of the three known CVD risk equations in the Korean human immunodeficiency virus/ Acquired Immune Deficiency Syndrome (HIV/AIDS) cohort. Materials and Methods The study parcitipants were HIV-infected patients in a Korean HIV/AIDS cohort enrolled from 19 hospitals between 2006 and 2017. Data collected at entry to the cohort were analyzed. The 5-year CVD risk in each participant was calculated using three CVD risk equations: reduced CVD prediction model of HIV-specific data collection on adverse effects of anti-HIV drugs (R-DAD), Framingham general CVD risk score (FRS), and Korean Coronary Heart Disease Risk Score (KRS). Results CVD events were observed in 11 of 586 HIV-infected patients during a 5-year (median) follow-up period. The incidence of CVD was 4.11 per 1,000 person-years. Older age (64 vs. 41 years, P = 0.005) and diabetes mellitus (45.5% vs. 6.4%, P <0.001) were more frequent in patients with CVD. Using R-DAD, FRS, and KRS, 1.9%, 2.4%, and 0.7% of patients, respectively, were considered to have a very high risk (≥10%) of 5-year CVD. The discriminatory capacities of the three prediction models were good, with c-statistic values of 0.829 (P <0.001) for R-DAD, 0.824 (P <0.001) for FRS, and 0.850 (P = 0.001) for KRS. Conclusion The FRS, R-DAD, and KRS performed well in the Korean HIV/AIDS cohort. A larger cohort and a longer period of follow-up may be necessary to demonstrate the risk factors and develop an independent CVD risk prediction model specific to Korean patients with HIV.

This study attempted to analyze the effect of elementary school children's use of after-school public care services on self-care time and participation in private education, and to present policy proposals for the development of after-school public care services. To this end, the data of 716 elementary school children who responded to all 8th to 13th Korean Children's Panels were analyzed using a panel probit model, a panel ordered probit model, and a two-way fixed effect model. The research results can be summarized in three ways. First, the use of public care showed a negative effect on the self-care time. Second, the marginal effect of the use of public care in reducing the self-care time was higher than that of the use of private education. Third, the use of public care has a negative effect on participation in private education. Based on the results of the study, this study suggested that policy intervention is necessary to resolve the mismatch between demand and supply for after-school public care for elementary school children. 본 연구는 초등아동의 방과후 공적 돌봄 서비스 이용이 이들의 돌봄 공백과 사교육 참여에 미치는 영향을 분석하고, 그 결과를 바탕으로 방과후 공적 돌봄 서비스의 발전을 위한 정책적 제안을 제시하고자 하였다. 이를 위해 한국아동패널 8∼13차에 모두 응답한 초등아동 716명의 자료를 패널 프로빗 모형, 패널 순서형 프로빗 모형, 이원고정효과 모형을 활용해 분석하였다. 연구결과는 세 가지로 요약할 수 있다. 첫째, 공적 돌봄 이용은 돌봄 공백에 통계적으로 유의한 부(-)의 영향을 나타내는 것으로 여겨진다. 둘째, 돌봄 공백 경감에 있어 공적 돌봄 이용의 한계효과가 사교육 이용의 한계효과 대비 높게 나타났다. 셋째, 공적 돌봄 이용은 사교육 참여에 통계적으로 유의한 부(-)의 영향을 미친다. 연구결과를 바탕으로 본 연구는 초등아동 대상의 방과후 공적 돌봄에 대한 수요와 공급의 미스매치 해소를 위한 정책적 개입이 필요함을 제안하였다.

Purpose: Autism spectrum disorder impacts children's social, sensory, and language development, necessitating specialized educational support. Special classrooms play a crucial role in providing an appropriate learning environment for children with autism. However, there is a lack of systematic research on creating effective environments in these special classrooms. Methods: This study aims to gain a comprehensive and systematic understanding of the environmental composition of special classrooms for children with autism spectrum disorder, using the following systematic methodologies including literature review and case study. Results: Sensory spaces in special classrooms for children with autism help regulate sensory stimuli and promote sensory development. They provide stability, reducing stress from excessive stimuli, and enhance emotional stability. These spaces also promote communication and interaction among children and expand the diversity of learning activities, enriching experiences and stimulating interest in learning. Implications: Based on the results, we propose suggestions for improving the environment of special classrooms for children with autism spectrum disorder and provide direction for the design of such environments.
