Purpose: The purpose of this study was to investigate nursing students' awareness and performance on standard precautions and to provide meaningful information for nursing students' education regarding hospital infection control. Method: Four hundred forty seven nursing students at 6 universities in D-city participated in this study. Data collection was conducted from March to April 2011. Students' awareness and performance on standard precautions of infection control in hospitals were measured using the modified 2007 CDC standard precautions guidelines. Data analysis was performed using the SPSS WIN 18.0 program, descriptive statistics, t-test, and ANOVA. Results: The level of students' awareness in the standard precautions was higher than performance. The higher levels of students' awareness and performance on standard precautions included patient care equipment, safe injection practices, and worker safety. The lower levels of students' awareness and performance on standard precautions included hand hygiene and personal protective equipment. There was no difference in the students' awareness and performance of standard precautions according to their characteristics. Conclusions: Based on the findings of this study, hand hygiene and personal protective equipment need to be stressed more within the program to improve nursing students' infection control techniques.

The purpose of the study was to investigate the relationships between dietitian’s job satisfaction and perception of barriers to HACCP implementation and food safety/sanitation management performance in school food service. An e-mail survey was conducted to 144 dietitians in Gyeongbuk Province. A response rate was 57.6%(N=83) and data were analyzed using SPSS Windows(ver. 10.0). Dietitians were more satisfied with ‘supervision’ and 'co-workers' than 'pay' and 'promotion.' Dietitians perceived 'lack of teachers' support on student education' and ‘limited availability of facilities/equipment' as the biggest challenges in implementing a HACCP system. A total score of sanitation/safety management performance evaluated by school districts was 92 out of 100. By category, 'safety management' and 'personal hygiene' were rated the highest whereas 'facilities/equipment' and 'HACCP system' categories were rated the lowest. The food sanitation/safety management performance scores were not correlated to dietitian’s job satisfaction, but significantly correlated to dietitian’s perceptions of barriers to HACCP implementation. As dietitians perceived facilities/equipment-related barriers greater, the scores of 'facilities/equipment(p<.01),' 'production process(p<.05),' and 'total score(p<.01)' were significantly lower. The findings suggest that more investment on facilities/equipment are needed for food safety improvement and successful HACCP implementation in school food service. Proper facilities and equipment will make employees monitor CCPs and take corrective actions more easily.

The purpose of this study was to investigate the foodservice employees' awareness and performance in sanitation and customers' satisfaction with sanitation in large sized restaurants in Korea. Sanitation inspections were carried out in 200 large Korean, Western, Chinese, and Japanese style restaurants, and in buffet-style restaurants in Daegu and Gyeongbuk province. Foodservice employees' awareness of sanitation and customers' satisfaction with sanitation were investigated by interviewing 317 foodservice employees and 205 customers. Results of the inspection of restaurants showed low performance in food handling, employees' hygiene (hygienic) practices, and in cleaning food processing equipment. Scores of the foodservice employees' awareness in Chinese style restaurants were significantly lower than scores of workers in western restaurants. Foodservice employees had low awareness of sanitation procedures used for food storage and cleaning of equipment in Korean, Chinese, and Japanese style restaurants. Foodservice employees had low awareness of equipment cleaning, inspection and food distribution in western style restaurants and of equipment cleaning and food handling in buffet-style restaurants. Foodservice employees at all restaurants had the lowest performance in terms of HACCP. This shows that HACCP application and recording have not yet been properly carried out at restaurants in Korea. Foodservice employees had low performance scores in food handling, vegetable disinfection and disinfection after hand washing. Research on customers' satisfaction with sanitation revealed a low rating of kitchens and foodservice employees at all restaurants. Customers had low satisfaction with servers and kitchen environments in Korean style restaurants with food, tableware, utensils and servers in western style restaurants; with food and kitchen environments in Chinese style restaurants with servers, tableware, and utensils in Japanese style restaurants and with kitchen environments and servers in buffet-style restaurants. Therefore, cleanliness of kitchen facilities and equipment, and hygienic food handling procedures by workers in restaurants are urgently needed.

Purpose: The research aims at examining the impact of marketer capabilities and persistence on marketer performance and distribution of agricultural product facilities. Research design, data, and methodology: The research employs quantitative methods using a cross-sectional design survey by analyzing the marketer of agricultural production facilities. Sampling was done using the purposive sampling technique and data were taken from 235 respondents. The data were then processed using SEM-PLS. Results: The findings reveal that both marketer capabilities and marketer persistence significantly impact the performance of agricultural product facility marketers. Notably, marketer persistence exerts a more dominant influence on marketer performance than marketer capabilities. Effective communication and coordination between the sales team and the distribution center emerge as crucial factors determining the success of distributing agricultural equipment to reach farmers' land at the optimal time. Conclusions: The findings offer valuable managerial insights for agricultural product facility companies seeking to enhance marketer performance. To achieve this, companies should focus on increasing marketer persistence, with an emphasis on nurture-focused persistence rather than closure-focused persistence. Additionally, improving marketer capabilities is crucial, starting with relationship development, followed by trust building, customer retention, responsiveness, and acquisition. These strategies can collectively contribute to boosting marketer performance within the organization.
