여행의 형태가 정적인 자원보다는 동적이고 체험적이고 가족형으로 변화하는 추세에 따라 축제가 매우 선호되고 있다. 특히 역사적 사건, 시대, 인물을 주제로 개최되는 역사체험축제는 자녀를 둔 가족이 교육과 체험을 동시에 경험할 수 있어서 인기가 높다. 축제의 평가는 현재의 문제점을 진단하고 개선안을 도출하기 위한 절차로서 축제의 발전에 중요한 역할을 한다. 축제를 평가하는 방법 중 중요도-실행도 분석(Importance-Performance Analysis)은 만족도와 같은 단일 기준의 평가가 아니라 중요도와 실행도를 동시에 평가하고, 복잡한 통계기법이나 전문용어가 없어도 도표를 이용하여 가시적으로 문제점을 판단할 수 있기 때문에 일선 축제 담당자에게 유용한 도구가 될 수 있다. 본 연구에서 연천전곡리 구석기축제를 대상으로 중요도-실행도 분석을 실행한 결과 '음식의 독특함', '휴게시설', '기타 편의시설', '위생', '혼잡도' 등이 집중 영역에 포함되었다. 따라서 축제의 발전을 위해서 독특한 음식을 개발하고, 휴게시설과 기타 편의시설을 확충하고, 위생에 신경을 쓰고, 혼잡도는 낮출 수 있도록 노력해야 하겠다.

Objectives : An outbreak of salmonellosis occurred among the student s and staff of D primary school in Yeongcheon-si, 2004. This investigation was carried out to prevent any recurrence of this outbreak and to study the infection source and transmission of the salmonellosis. Methods : The authors conducted a questionnaire survey among 1,205 students and staff members from D primary school about the ingestion of the school lunch and drinking water, and the manifestation of their symptoms. The author examined rectal swabs, the tap water and microorganism cultures, and we also investigated the dining facility and water supply facility. Results : The diarrheal cases were defined as the confirmed cases or the persons who had diarrhea more than one time with symptoms such as fever, vomiting and tenesmus. The diarrheal attack rate was 28.0%. Ingestion of fried bean curd with egg had a significantly high association with the diarrheal attack rate (p<0.05), and the relative risk of the fried bean curd with egg was 10.68 (95% CI=3.88-29.41), as was determined by logistic regression analysis. The bacterial counts in the tap water of the food preparation room and toilet (first floor) exceeded the maximum permissible counts. S. Enteritidis bacteria were only cultured from the fried bean curd with egg of all the supplied foods on September 3, 2004. Conclusions : The major cause of salmonellosis was presumed to be the contaminated bean curd via contaminated tap water due to a water leak of a school water pipe. This contaminated bean curd was under prepared, which allowed the S. Enteritidis to survive and multiply prior to its ingestion.

Background: This study determined current status of laboratory biosafety in Nigerian veterinary research facilities. Methods: A questionnaire was developed to obtain information from researchers across Nigeria from July 2014 to July 2015. Information regarding demographics, knowledge of laboratory biosafety, availability and proper use of personal protective equipment (PPE), any priority pathogens researched, attitude on and use of standard laboratory practices, and biosafety awareness was obtained using a numeric scoring system. Data were analyzed with descriptive statistics, and univariate and multivariate logistic regression. Results: A total of 74 participants from 19 facilities completed the questionnaire. General knowledge scores ranged from 3 to 28 (out of 28 possible points), with 94.6% of respondents receiving low scores (scores < mean + 1 standard deviation). Very few (17.6%) reported availability or use PPE. Many participants (63.5%) reported no access to biosafety level (BSL)-1-3 facilities. None reported availability of a BSL-4 facility. Knowledge scores pertaining to biosafety management practices ranged from 0 to 14 (out of 14 possible points) with 47.3% of respondents receiving good scores (scores > mean + 1 standard deviation). Only 16.2% of respondents (from four facilities) reported having biosafety officers. Rabies virus was the most researched pathogen (31.1% of respondents). The majority (71.6%) were unaware of laws guiding biosafety. Researchers [odds ratio (OR) = 18.0; 95% confidence interval (CI): 1.63, 198.5; p = 0.023], especially in BSL-2 (OR = 258.5; 95% CI: 12.71, 5256; p < 0.001) facility of research institute (OR = 25.0; 95% CI: 5.18, 120.6; p < 0.001), are more likely to have adequate access to and properly utilize biosafety devices and PPE. Conclusions: Current knowledge of laboratory biosafety is limited except among a few researchers.

Objectives: This paper aimed to provide an in-depth analysis of the factors influencing the dietary habits of male and female workers at a facility in Gwangju and their awareness of the same. Methods: A total of 32 workers were divided into eight groups based on work type, gender, and age, and focus group interviews (FGIs) were conducted. The FGIs included cognitive, behavioral, and environmental questionnaires based on dietary habits and the social cognitive theory. The interviews were analyzed by subject and sub-subject using audio recordings and transcriptions. Results: Male workers in the concerned company favored meat while female workers preferred vegetables, yet by and large, the preferences were irregular. Male workers living alone frequently ate ready meals and female workers often skipped meals. An analysis of the factors influencing the study subjects' dietary habits from the cognitive, behavioral, and environmental perspectives showed that the main factors negatively affecting their dietary habits were shiftwork, living alone, and drinking. Workers were unaware of these factors and their poor eating habits. Instead, male workers complained of poor cooking skills, while female workers complained of loneliness. Workers thus appeared to need the support of nutrition education and a counseling assistant to cope with this situation. Conclusions: The study identified the fact that the absence of nutrition education left the workers unaware of their poor eating habits. The workers would need counseling and support to help them build healthy dietary habits. It would also be necessary to focus on raising the workers' cognitive awareness of dietary habits and enhancing their behavioral ability to cope with bad eating habits through nutrition education that reflects the reality of their situation.

BACKGROUND/OBJECTIVES: South Korea is representative of countries experiencing rapid societal aging. This study aimed to understand the current status of foodservice nutrition management provided to welfare facilities for the elderly and to understand improvements after support from "the Center for Social Welfare Foodservice Management (CSWFM)" in Cheongju City. SUBJECTS/METHODS: The status of foodservice nutrition management was assessed by dietitians and hired by the CSWFM, who visited 40 welfare facilities (registered members of the CSWFM) for the elderly in Cheongju City. After visiting each facility three times from July to December 2019, the results of inspections on four areas, that is, 'menu', 'meal provision', 'cooking', and 'distribution' management for 2nd and 3rd visits (support visits) were compared with results obtained at initial visits. RESULTS: Before support as determined during 1st visits, compliance rates with 'menu', 'meal provision', 'cooking', and 'distribution' requirements were 72.1%, 75.5%, 58.3%, and 77.5%, respectively. The mean compliance rate for all 15 items on the questionnaire used was 70.8%. Items with low compliance rates were 'Is the soup provided by foodservice at the recommended salinity?' (compliance rate 37.5%) and 'Is the foodservice cooking conducted by referring to a recipe?' (42.5%). At the two support visits, mean compliance rates increased significantly (P < 0.01, P < 0.001), mean total score had significantly increased from 71.80 to 90.26 (P < 0.001), and mean soup salinity decreased significantly from 0.82% at 1st visits to 0.68% (P < 0.001) and 0.56% (P < 0.001) at the 1st and second follow-up visits. CONCLUSIONS: These results show that the status of nutrition management at welfare facilities for the elderly was much improved by CSWFM involvement, and indicate the CSWFM should continuously provide nutrition management support to facilities and that finances and opportunities for more welfare facilities for the elderly be expanded.

The purpose of this study was to determine the empirical cause-effect relationships among business ethical values and person-organization fit, job satisfaction, turnover intent, and organizational performance within family restaurants and feeding facilities. Self-administered questionnaires were completed by 459 restaurant employees. The SPSS and Amos programs were then applied to the data to perform frequency, factor, reliability, correlation and SEM analyses. The primary results are as follows. First, business ethical values had a significant positive effect on person-organization fit. Second, person-organization fit had a significant positive effect on job satisfaction, and a significant negative effect on turnover intent. Third, job satisfaction had a significant positive effect, and turnover intent had a significant negative effect, on organizational performance. Finally, upon verifying the possible direct and indirect effects of business ethical values within family restaurants and feeding facilities, it was determined that the ethical values had significant direct and indirect effects on person-organization fit, job satisfaction, turnover intent, and organizational performance. These findings have various implications. For example, an improved in-house ethical working environment leads to greaterperson-organization fit, and having employees that feel there is better in-house ethical reliability leads to greater consistency between personal and organizational values, resulting in higher job satisfaction and ultimately organizational performance.

This research suggested the hygienic spatial composition of sell-service restaurants applying HACCP(Hazard Analysis and Critical Control Point System). The circulation of the food, dishes, waste, workers and customers were each fractionated and arranged according to the hygienic sequence of cooking food in kitchen and process for eating food within the customer space. The spaces were separated by the degree of cleanness(clean area, semi-clean area, contaminated area). After that, hygiene facilities to remove contamination and pass facilities intended to control moving were added at the possible points of cross-contamination in oder to prevent the cross-contamination. For hygienic spatial composition of self-service restaurant, the following should be acknowledged: In the kitchen, spaces in which the food is handled after being heated should be located in the clean area. As of the customer space, spaces where dishes are prepared, food and water is received, and the table hall should be located in the clean area. Food circulation should flow from the contaminated area to the clean area. Food, dishes, waste should be moved through pass facilities so that workers do not have to come and go between other areas of cleanness. Also lockers for private clothes and lockers for uniforms should be separated. Hygiene facilities should be easily accessible so that workers can use them whenever they enter their working area. The contaminated area where dirty dishes are dealed with should be separated from the clean area. Waste should be thrown out without crossing cooking areas. As of customer circulation, the hygiene facility for hand washing should be located near the space where dishes for self-service are placed. The customer circulation should lead customers to leave restaurants after giving back the dirty dishes in the contaminated area.
