Fresh-cut foods have been widely used in the school foodservice industry due to their convenience and saving effects of labor and working hours. This study evaluated the effectiveness of using fresh-cut foods in school foodservice with respect to cost efficiency, customer satisfaction, employee satisfaction, and productivity. First, in terms of cost efficiency, the cost of the fresh-cut food per meal price significantly increased by 2.6% via the new production plan. Meanwhile, the costs of labor and food wastes significantly decreased by 3.0% and 0.3%, respectively, after implementing the new plan. Second, customer satisfaction towards foodservice significantly increased, from 2.94 points prior to the new plan to 3.45 points. Third, foodservice productivity such as of the number of meals per full-time equivalent employee increased by 5.7 meals, from 143.0 meals to 148.7 meals after intervention. The productivity index of work hours for producing a meal also increased and was reflected by a work time reduction of 0.77 minutes, specifically from 4.25 minutes to 3.48 minutes. The labor cost per meal also decreased by 29.9 won, from 331.91 won to 301.97 won, but there was no significant difference. Through these results, we identified that using pre-process foods in school foodservice has positive effects on labor saving, customer satisfaction, and employee work satisfaction.

BACKGROUND: This paper presents the findings of a pilot research survey which assessed the degree of balance between safety and productivity, and its relationship with awareness and communication of human factors and safety rules in the aircraft manufacturing environment. METHODS: The study was carried out at two Australian aircraft manufacturing facilities where a Likert-scale questionnaire was administered to a representative sample. The research instrument included topics relevant to the safety and human factors training provided to the target workforce. The answers were processed in overall, and against demographic characteristics of the sample population. RESULTS: The workers were sufficiently aware of how human factors and safety rules influence their performance and acknowledged that supervisors had adequately communicated such topics. Safety and productivity seemed equally balanced across the sample. A preference for the former over the latter was associated with a higher awareness about human factors and safety rules, but not linked with safety communication. The size of the facility and the length and type of employment were occasionally correlated with responses to some communication and human factors topics and the equilibrium between productivity and safety. CONCLUSION: Although human factors training had been provided and sufficient bidirectional communication was present across the sample, it seems that quality and complexity factors might have influenced the effects of those safety related practices on the safety–productivity balance for specific parts of the population studied. Customization of safety training and communication to specific characteristics of employees may be necessary to achieve the desired outcomes.

In vitro fruiting bodies were produced from ten different isolates of Cordyceps militaris EFCC C-5736, EFCC C-5941, EFCC C-5976, EFCC C-6040, EFCC C-6849, EFCC C-7268, EFCC C-7342, EFCC C-7992, EFCC C-8027 and EFCC C-8549. Single ascospores were isolated from in vitro grown fruiting bodies and used for fruiting body production in brown rice medium by both intra-strain crossing and out-crossing. Length and dry wt. of stromata grown in vitro were measured. Strains producing highest dry wt. of stromata were selected. Both intra-strain crossings and inter-strain crossings of single ascospore strains were found to produce profuse fruiting bodies of C. militaris.

Objective. To determine operating room efficiency for elective ophthalmologic surgeries requiring general anesthesia in a public tertiary institution based on standard efficiency parameters. Methods. Prospective observational cross-sectional study of randomly selected elective cases requiring general anesthesia from April 2019 to June 2019 in the Department of Ophthalmology of the Philippine General Hospital. A single third-party observer recorded operating room milestones from which efficiency parameters were determined and compared with local and international guidelines and efficiency benchmarks. Results. A total of fifty cases from the Retina, Plastic, Orbit, Glaucoma, and Motility services were observed. None started on the specified start time of 6:30 a.m., with surgeries starting an average of 52 ± 11.90 minutes after. Across subspecialties, median surgical preparation time was statistically significant (χ2: 12.01, p: 0.02), with the Retina and Orbit services having the most extended duration. Across age groups, pediatric cases had lower mean anesthesia preparation times (t: 2.15, df: 48, p: 0.04) and median trans-out lag times (χ2: 4.56, p: 0.03) than adults. Overall, more than 60% of cases reached targets for induction and surgical lag time. Turnaround for adult and pediatric patients was 75 ± 22.77 minutes and 71 ± 14.91 minutes, respectively. Benchmarking analysis showed that the first case on time, entry lag, and exit lag were below the 50th percentile while the room turnover time was above the 95th percentile. Conclusion. Ensuring efficiency requires a multidisciplinary team approach. This research can guide administrators in determining interventions to increase operating room efficiency.

OBJECTIVE: To evaluate the comprehensive technical efficiency of the tertiary public hospitals in Beijing between 2006 and 2015 and explore its influencing factors, so as to propose corresponding policy suggestions. METHODS: The data envelopment analysis was employed to evaluate the comprehensive technical efficiency, pure technical efficiency and scale efficiency of the tertiary public hospitals in Beijing. Malmquist index model was used to analyze the changes of the above three dynamic efficiencies. Finally, randomeffect panel tobit model was utilized to analyze the influencing factors of the comprehensive technical efficiency. RESULTS: The average comprehensive technical efficiency and pure technical efficiency of the tertiary public hospitals in Beijing were relatively high, and they had respectively increased from 0.44 and 0.51 in 2006 to 0.62 and 0.68 in 2015, and the highest proportion of two kinds of efficiency values was between 0.5 and 0.8. Most of the scale efficiency values distributed between 0.8 and 1.0, and the majority of hospitals were in a state of decreasing returns to scale. The total factor productivity of hospitals had been increasing at an average rate of 5.78% per year due to the double progress of technical efficiency and technology at annual rates of 3.77% and 1.94% respectively, further decomposing technological efficiency change, and the pure technical efficiency change increased at the speed of 3.21% per year, and the annual average rate of progress in scale efficiency was only 0.53%. The comprehensive technical efficiency was positively correlated with the turnover rate of beds, annual visits per doctor, the ratio of doctors to nurses, and negatively correlated with the number of beds, the ratio of outpatients to inpatients, the proportion of medical technical personnel, and the proportion of drugs. CONCLUSION Future health policies should strictly control the scale of tertiary public hospitals, pay attention to the innovation and application of hospital technology, change the hospital internal management level and management model, promote refined management, and achieve sustainable development.

PURPOSE: The purpose of this study was to identify the levels of customer orientation in nurses whose work experience was between 1 and 5 years and to examine factors associated with customer orientation and nursing productivity. METHODS: For this descriptive correlational study, nurses (N=164) were recruited from a University Hospital in B city, from November 1 to 23, 2012. Questionnaires included measures of customer orientation, nursing productivity, organizational commitment, job stress, and turnover intention. Data were analysed with the SPSS/WIN 18.0 program using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and stepwise multiple regression. RESULTS: The mean age of participants was 25 years, 96% were single, and 54.9% had a bachelor degree. Organizational commitment (beta=.387) and job stress (beta=.280) significantly explained the variance in customer orientation (R2=15.8). Customer orientation (beta=.479), education level (beta=.196), and turnover intention (beta=-.184) significantly explained the variance in nursing productivity (R2=35.3). Customer orientation was the most important factor in explaining the variance in the nursing productivity. CONCLUSION: This study highlighted the relationship between customer orientation and nursing productivity. Improving the customer orientation could result in increasing nursing productivity. Future managerial intervention to improve customer orientation is warranted.

PURPOSE: This study is to investigate the job stress and presenteeism of nurses with work shift. METHODS: The data were collected through questionnaires from 281 clinical nurses working for a university hospital located in D city from 13 to 28 of February, 2009. The data were analyzed by descriptive statistics, t-test, ANOVA, Scheffe verification test, Pearson correlation coefficient and multiple linear regression using SPSS/WIN 16.0. RESULTS: The mean score of job stress was 3.47. Work overload and psychological burden scored the highest point as the sub-category of work stress factor. Work performance loss out of presenteeism showed 26.89 and perceived productivity, 79.79. Also 94.7% of respondents answered they had health problems. A significantly positive correlation was found among job stress, work performance loss and health issue. To determine the factors affecting persenteeism, work performance loss was associated with work overload and perceived productivity with interpersonal relationship conflict. CONCLUSION: Based on the findings of the study, job stress is positively correlated with work performance loss, and health problems. Therefore, health problems of nurses with work shift need to be considered and plans to manage their job stress affecting presenteeism need to be developed at an earlier stage.

BACKGROUND: Job stress and job satisfaction are important factors affecting workforce productivity. This study was carried out to investigate the job stress, job satisfaction, and workforce productivity levels, to examine the effects of job stress and job satisfaction on workforce productivity, and to identify factors associated with productivity decrement among employees of an Iranian petrochemical industry. METHODS: In this study, 125 randomly selected employees of an Iranian petrochemical company participated. The data were collected using the demographic questionnaire, Osipow occupational stress questionnaire to investigate the level of job stress, Job Descriptive Index to examine job satisfaction, and Hersey and Goldsmith questionnaire to investigate productivity in the study population. RESULTS: The levels of employees' perceived job stress and job satisfaction were moderate-high and moderate, respectively. Also, their productivity was evaluated as moderate. Although the relationship between job stress and productivity indices was not statistically significant, the positive correlation between job satisfaction and productivity indices was statistically significant. The regression modeling demonstrated that productivity was significantly associated with shift schedule, the second and the third dimensions of job stress (role insufficiency and role ambiguity), and the second dimension of job satisfaction (supervision). CONCLUSION: Corrective measures are necessary to improve the shift work system. “Role insufficiency” and “role ambiguity” should be improved and supervisor support must be increased to reduce job stress and increase job satisfaction and productivity.
