Lactic acid bacteria (LAB) growth in processed meat products produces slime. In this study, 10 different biofilmforming LAB, including Leuconostoc mesenteroides, Lacticaseibacillus paracasei, Levilactobacillus brevis, Lactiplantibacillus plantarum, Leuconostoc citreum, Weissella viridescens, and Latilactobacillus sakei, were isolated from various meat products and identified based on 16S rRNA gene analysis. To inhibit biofilm formation by LABs, Eisenia bicycles methanolic extract (EB) and ethyl acetate soluble fraction (EA) were used as antibacterial and antibiofilm agents, respectively. Furthermore, EA and EB were employed to synthesize gold nanoparticles (AuNPs) such as EB-AuNPs and EA-AuNPs, which could serve as antibiofilm agents against the isolated LAB. These findings demonstrate that EA, EB-AuNPs, and EA-AuNPs exhibit significant antibacterial activity against the isolated LAB. Furthermore, EB-AuNPs reduced L. citreum biofilm production, whereas EA-AuNPs inhibited L. mesenteroides and L. brevis biofilm formation. The current results suggest that EB-AuNPs and EA-AuNPs can be used as nanomaterials to inhibit LAB that form biofilms on meat products.

한국 진주·삼천포 농악의 설장고춤과 중국 요족 장고춤의 비교연구

오도경,김미숙 영남춤학회 2013 영남춤학회誌 Vol.1 No.1

This study with focusing on the Korea Janggo dance emerging as a leading brand in the world of dance made a comparative study between Korea and Chinese Janggo dance among the dances consisting of Ak(music)· Ga(song)· Mu(dance). I felt the need to study to difference about Janggo chumsawi in the two countries' Janggo dance with common background of the farming community beyond the capabilities of the instrument as the development of dance. Analysis was focused on Jinju-Samcheonpo Nong-ak's Seoljanggo dance in Korea and Yao Zu's Janggo dance in China. Thus, I conclude it with explaining the similarities, differences and aesthetic characteristics in the two countries' Janggo dance. 이 연구는 무용에 있어 악·가·무로 어우러진 춤 중에서 한국의 대표 브랜드로 떠오르고 있는 장고춤에 주목하여 한국과 중국의 장고춤에 대해 비교 연구 하였다. 경제, 정치, 문화, 예술 등의 여러 분야의 연구가 서양에서 동양으로 관심이 향하고 있으며 그 중심에는 동북아시아의 각 나라에 대한 연구가 활발히 이루어지고 있다. 그러나 아직도 발굴되어져야 할 문화예술은 많다. 연구자는 한국과 중국의 장고 춤이 중국에서 한국으로 장고가 건너왔으며, 농경사회를 배경으로 하여 악기로 써의 기능을 넘어 춤으로 발전했다는 공통점을 알게 되었다. 양국의 장고 모양을 보았을 때 춤사위의 차이가 분명히 있을 것이라는 점에서 이 연구의 필요성을 느 꼈다. 다만, 한국에서는 장고를 가지고 춤을 추는 종류가 많았으나 중국의 경우 요족과 조선족이라는 소수민족으로 분류되어 있었다. 그래서 농경사회의 공통 점을 가지고 있는 진주·삼천포 농악 설장고춤과 중국의 요족 장고춤을 선택하여 집 중적으로 분석 연구하였다. 그리하여 두 나라의 장고춤의 복식, 소도구, 장단, 춤 사위를 비교 연구하였으며, 춤의 유사성과 차이성과 그 미적 특성을 밝혀 결론을 내렸다.

본 연구에서는 보육시설 실내공기에서 분리된 식중독 균 주의 독소 유전자 분포와 항생제 내성을 분석하여 보육시설 실내공기에 의한 식중독 발생을 사전 예방하고 식중독 발생 시 적절한 치료를 위한 기초자료를 제공하고자 하였다. 어린이집 실내공기에서 분리된 Staphylococcus aureus 16주, Bacillus cereus 37주를 실험대상으로 하였다. S. aureus와 B. cereus 독소 유전자는 PCR 방법으로 검출하였다. 항생제 감수성 실험은 Clinical and Laboratory Standard Institute의 디스크 확산법에 따라 실험하였다. S. aureus 16 균주 중 11 균주(68.6%)에서 seg와 sei 독소 유전자가 검출되었다. B. cereus 37 균주 모두에서 nheA와 nheB 독소 유전자가 검출되었다. B. cereus 독소 유전자 패턴은 총 12개로 나타났으며 nheA-nheB-nheC 독소 유전 자가 가장 중요한 패턴으로 나타났다. S. aureus 16 균주의 항생제 감수성실험 결과 ampicillin과 penicillin 항생제 에 93.8%, 87.5% 내성을 나타내었으나 methicillin resistance Staphylococcus aureus와 vacomycin resistance Staphylococcus aureus는 검출되지 않았다. B. cereus 37 균주의 항생제 감수성 실험 결과 ampicillin과 penicillin 항생제에 100% 내성을 나타냈었다. 이러한 결과를 종합하여 볼 때 보육시 설 실내공기에 오염된 S. aureus와 B. cereus에 의한 식중독을 발생을 예방하기 위하여 주기적인 환기와 공기 질 관리가 필요한 것으로 판단되었다. In this study, toxin gene and antibiotic resistance of food poisoning strains isolated from indoor air in the cafeteria were analyzed to prevent food poisoning. Staphylococcus aureus (16 strains) and Bacillus cereus (37 strains) isolated from indoor air in child care center were tested. The toxin genes of S. aureus and B. cereus were detected by PCR assay. The antimicrobial susceptibility test followed the disc diffusion method described by the Clinical and Laboratory Standard Institute. The seg and sei toxin genes were detected in 11 of 16 S. aureus strains (68.6%). The nheA and nheB toxin genes were detected in 37 B. cereus strains. In this study, a total of 12 toxin gene patterns of B. cereus were found, among which the nheA-nheB-nheC toxin gene was found to be the most frequent pattern. The result of the antimicrobial susceptibility test of S. aureus revealed 93.8% and 87.5% resistance to ampicillin and penicillin antibiotics, but methicillin resistance S. aureus and vancomycin resistance S. aureus were not detected. All 37 B. cereus tested in this study were resistant to ampicillin and penicillin antibiotics. Based on the result of this study, it was judged that regular ventilation and air quality management were necessary to prevent food poisoning caused by S. aureus and B. cereus contaminated in the indoor air of child care centers.

오도경(Do Kyeong Oh),박철현(Cheol Hyun Park) 한국피해자학회 2016 被害者學硏究 Vol.24 No.2

This study is on sexual–harassment victimizations in public transports of the woman students(N=501) of D university in Busan, S. Korea, through a victim survey. Sample was selected with quota sampling by the distribution of departments. This data was analyzed with logistic regression technique on binary response, using SAS and SPSS. All hypotheses were inferred from lifestyle theory and routine activity theory and these hypotheses were divided into the proximity and expose with criminals, target attractiveness, and the absence of guardianships. Analysis on this data shows that these three factors, related with rational choice perspective, have some significant effects on sexual harassment victimization in public transports, but their effects is very differential in their effect sizes. Some variables of the proximity and expose with criminals and some variables of the absence of guardianships have only a small effects on sexual harassment victimization. But mainly wearing a showy and sexy dress, which is a variable of target attractiveness in sexual–harassment victimization, has a strong effect on sexual harassment victimization. Also, mainly wearing a showy and sexy dress has a stronger effect on serious sexual harassment victimizations(such as a sexual contact or grouping) than mild sexual harassment victimizations(such as a verbal harassment, a leaning, a picturing a part of body, and etc..)

Oysters are a highly consumed seafood throughout Korea, but they have a short shelf life because they support rapid microbial growth due to their of high moisture content and fragile muscle tissue. We examined natural food additives including lactic acid bacteria fermentation powder, rosemary extract, and lemon juice for their ability to preserve raw oyster Crassostrea gigas quality. Samples were stored at 4℃, and microbiological and physicochemical analyses were conducted. Among the natural additives tested, lemon juice was the most effective. Lemon juice was thus applied at different concentrations (50-300 ppm) to quantitatively assess its effect on total viable cell count, pH, glycogen, soluble protein, and turbidity. 200 ppm was confirmed to be optimal, and is projected to extend shelf life by 2 days compared to the control group.

In this study, the effect of MnSO4 on the insecticidal crystal (IC) produced by Bacillus thuringiensis for a rapid detection medium was analyzed. The strains used included one B. thuringiensis reference (KCTC 1511) and nine wild-type strains. The IC in B. thuringiensis was detected following the method published by the Ministry of Food and Drug Safety in Korea. In the nutrient agar to which 0.005% MnSO4 was added, IC was observed on two of the three plates after 48 hours of incubation and on all three plates after 120 hours. In AK agar, IC was observed on one and two of the three plates after 48 and 96 hours of incubation, respectively. These results indicated that 0.005% MnSO4 nutrient agar is more appropriate than AK agar for production of IC in B. thuringiensis. The effect of various MnSO4 concentrations on IC production was studied after 24 hours of incubation. IC was produced on 1 of the 10 plates with 0.000% MnSO4 nutrient agar, 2 of the 10 plates with 0.001% MnSO4 nutrient agar, and 3 of the 10 plates with 0.002% MnSO4 nutrient agar. IC was not observed for the other nutrient agars containing 0.003%–0.009% MnSO4. These results indicated that nutrient agar with 0.002% MnSO4 led to the most rapid production of IC by B. thuringiensis after 24 hours of incubation. However, the conditions for IC production by B. thuringiensis depended on the incubation conditions and strain activity. Therefore, further studies are needed to verify the effects of 0.002% MnSO4 on the production of IC by various Bacillus thuringiensis strains.

As a result of analyzing the domestic and foreign HACCP systems, advanced countries mandated HACCP system on all foods to strengthen food safety management and USA, EU and China do not apply small-scale HACCP system. Looking at the cases of food safety accidents in Korea and the non-compliance rate of HACCP certification evaluation by size, the accident rate of companies without HACCP certification was 31.2% higher than that of companies with HACCP certification. The nonconformity rate of food inspection standards was analyzed to be 89.0% higher than that of HACCP certification companies. Based on the international trend of food safety management and the frequency of food safety accidents, it is proposed to gradually expand the mandatory application of HACCP system in Korea to all foods, and to change the small-scale HACCP standard from less than 500 million Korean won or 21 employees to less than 500 million Korean won.
