In an industrial Era, OJT(On-the-Job Training) has been accepted as the field learning. But in a breaking up era, traditional field training needs to change and make an evolutionary model. Also, we need to make evolutionary model for various changing ways and means and need means to maximize the transformation of learning by operating learning organization. In knowledge based society, as people work and learn new knowledge in order to pass the experience knowledge and capabilities, they are not the traditional relationship between trainer and trainee but maximize work and learning, development and performance through several different ways. So, the study about new learning model is needed because the learning is creating the value and makes low cost and high efficiency about the elements of cost and time. We study the evolutionary model, OJF(On-the-Job Facilitating) - new learning methodology - through operating learning organization in S Electronics and its application practices.

The purpose of this study was to investigate food sanitation status in elderly welfare facilities and assess the performance of food sanitation practices. Twenty elderly welfare facilities out of 85 located in Seoul with a capacity of fewer than 50 persons participated. The food sanitation status of worktable, kitchen utensils (knives, cutting boards, ladles, spoons), and tableware and bowls were examined by ATP bioluminescence. The results found that the ATP value of knife was the highest. Those of ladles appeared relatively higher than others. Meanwhile, the tableware and bowls, although washed everyday after meals, had the lowest ATP value. This study also conducted a survey on the food sanitation practices of 32 cooking employees in the 20 facilities. Fifty-six percent were in their 40s, and 53% had graduated from high school. More than half (66%) of them had no certification of cooking. Half of the respondents had worked for at least 5 years in food service facilities, and had received food sanitation training. Among them, 31% said they applied food sanitation training while working, and 47% responded the training was very helpful. The foodservice employees demonstrated good food sanitation practices. The results show that food sanitation performance of the workers significantly differed according to their age, education level, total work experience in food service facilities, chef certification, and prior food sanitation experience.

Background: In this study, the association of work and demographic characteristics with different traffic offenses committed by food delivery riders in Greece was examined. Previous research has identified various factors related to risky driving however, there is a need for exploring the complex interrelationship of work-related factors underlying risky driving behavior. Materials and Methods: A 2-items uestionnaire was used exploring delivery riders demographic characteristics, terms of employment, issues of concern during work and type of traffic offenses committed. In total, uestionnaires were analyzed using logistic regression in order to identify characteristics independently associated with serious traffic offenses, namely, red-light running and helmet non-use. Results: The analysis showed that: (i) typical health and safety measures had no effect on serious traffic offenses, (ii) young age was related to both offenses however (iii) different sets of work conditions were associated with reports of red-light running (i.e. low work experience, use of personal vehicle for work, and payment by hour) and helmet non-use respectively (i.e. intense work pace, high tip income per day and low concern about vehicle condition). Conclusion: The above findings provide evidence that serious traffic offenses are manifestations of underlying conflict experienced by the riders between safety and various performance criteria. Each one of the two offenses is related to different rider profiles aiming to satisfy different goals, namely, those mainly trying to maximize profit non-helmet users and those, mostly inexperienced ones, trying to cope with work pressure red light runners. Potential regulatory measures to alleviate risky practices are discussed.

Purpose: Prior studies regarding ethical management on worker's performance have primarily focused on specific industries or regions, potentially limiting the generalizability. This gap in knowledge underscores the need for a comprehensive investigation that considers a diverse range of industries and thoroughly examines the multifaceted aspects of ethical management. Research design, data and methodology: The academic search platform used for this study was 'Google Scholar', 'Scopus', and 'Web of Science' indexes various scholarly articles, including peer-reviewed journals and books. By utilizing specific search terms such as "corporate ethical management" and "employee performance," a vast pool of relevant studies was identified. Results: The findings indicated four effects: first, a positive correlation between ethical management practices and heightened employee motivation and engagement; second, an augmentation in organizational commitment and job satisfaction among employees; third, a reduction in turnover rates, indicating enhanced employee retention; and fourth, an elevation in overall productivity and performance outcomes. Conclusions: In sum, this study offers actionable insights, advocating for adopting and reinforcing ethical management strategies as a potent means to foster a high-performance work culture. These encompass fostering a robust ethical framework, cultivating a culture of transparency and open communication, and providing avenues for employees to voice ethical concerns without fear of retribution.

Purpose - The purpose of this study is to examine the impact of leader-member exchange (LMX) on employees' behaviors as well as to test the mediating roles of feeling trusted in the relationships. Research design, data, and methodology - Survey data were collected and analyzed from 285 sales people who work for various organizations in eastern China. The corresponding research models were verified using SPSS 22 and Amos 22. Results - The empirical results show that LMX plays a positive role in job performance and is positively related with subordinate's feelings of trust. However, the study was shown to have negative correlations between LMX and workplace ostracism. Feeling trusted by superiors mediated the relationship between LMX and job performance, resulting in employees being more motivated to do better, creating a positive synergetic effect. However, this relationship did not show to have significant mediating effects on the relationship between LMX and workplace ostracism. Conclusions - This study further enriches the relevant theory of LMX and has significance for management practices such as distribution sectors, guiding leaders to create a suitable team atmosphere. Leaders need to pay attention to build a high quality LMX with employees based on the empirical results of this study.

A survey was implemented to suggest basic data for assuring the safety of cooked foods in foodbank operations. A questionnaire consisted of total 48 items including general characteristics, basic inputs and perceived importance/performance of sanitary management. One hundred twenty-eight responses among the 267 nationwide foodbanks were used for the statistical analysis. About forty-one percent of foodbanks was operated a period of 1-3 years and 43.0% of them were managed by social welfare organizations. The number of staff was only 0.5 person per operation with the whole responsibility and 1.0 with additional work, and thus most of the work was managed by volunteers. Job satisfaction was shown to be moderate and was affected by specialty and salary mostly. The facilities and equipment in foodbanks were not enough to operate and freezers/refrigerators were the top priority to supplement. Most of the respondents attended a nationwide level sanitary education program (79.7%); but complained not enough frequency of education (90%). The sanitary status of the donated foods was considered as satisfactory but some safety practices had to be improved, including personnel expenses and operating costs in the district level, a sanitary awareness of the donors and a general management of the facilities arid equipment. An assessment on sanitary management resulted in an overall average of 4.45 out of 5 points in importance and 3.85 in performance showing the high level of sanitation perception in foodbank managers. From the IPA analysis, the fields found to be improved were sanitation management during cooking and temperature control as well as cleanliness and sanitation of both transport vehicle and refrigerator/freezer. To secure the food safety in foodbanks, consequently, personnel support, supplement of facilities and equipment, intense sanitation education and development of sanitation management program is needed.

Objectives: The aim of this study was to investigate sodium reduction practices in school foodservice in Daegu. Methods: The survey included 199 nutrition teachers and dietitians working at elementary, middle and high schools in Daegu. The survey topics included the following: the frequency of salinity measurement, workers in charge of the measurement, average salinity of the soup and stew served, frequency and difficulties of offering low-sodium meals, Importance-Performance Analysis (IPA) of sodium reduction methods in school foodservice and the need for political support in encouraging sodium reduction. Results: The mean salinity of the soup and stew was higher in high school foodservice than in elementary and middle school foodservice. Middle and high schools have difficulties in offering low-sodium meals due to concerns of decreasing satisfaction for the meals. The results of the IPA of programs to reduce sodium in school meals showed that most of the items in the cooking and serving stages were in the 2nd quadrant (Keep up the good work), and all purchasing and menu planning stages occupied the 3rd quadrant (Low priority). To reduce sodium in school meals, government support is required in developing low-sodium recipes for school foodservice, encouraging education on sodium reduction for school foodservice officials and developing low-sodium food for institutional foodservice. Conclusions: To encourage sodium reduction in school meals, the priority is to make low-sodium recipes available. Also, it is necessary to develop a program that calculates the sodium content in menus and processed foods through National Education Information System and to establish standards for sodium levels in school foodservice.

Background: The aims of this study were to determine hippuric acid levels in urine samples, airborne toluene levels, acute and chronic neurological symptoms, and to describe any correlation between urinary hippuric acid and airborne toluene. Methods: The hippuric acid concentration in the urine of 87 paint workers exposed to toluene at work (exposed group), and 87 nonexposed people (control group) was studied. Study participants were selected from similar factories in the same region. Urine samples were collected at the end of a shift and analyzed for hippuric acid by high performance liquid chromatography. Air samples for the estimation of toluene exposure were collected with diffusive personal samplers and the toluene quantified using gas-liquid chromatography. The two groups were also interviewed and observed about their work practices and health. Results: The median of the 87 airborne toluene levels was 55 ppm (range, 12-198 ppm). The median urinary hippuric acid level was 800 mg/g creatinine (range, 90-2547 mg/g creatinine). A statistically significant positive correlation was found between airborne toluene exposure and urine hippuric acid levels (r = 0.548, p < 0.01). Workers with acute symptoms had significantly higher hippuric acid levels than those who did not (p < 0.05). It was concluded that there was a significant correlation between toluene exposure, hippuric acid levels, and health (p < 0.001). Conclusion: There appears to be a significant correlation between workers exposure to toluene at work, their urine hippuric acid levels, and resulting symptoms of poor health. Improvements in working conditions and occupational health education are required at these workplaces. There was good correlation between urinary hippuric acid and airborne toluene levels.
