2.Effectiveness of the Preprocessed Foods on Productivity and Satisfaction in School Foodservices.
Journal of the Korean Dietetic Association 2009;15(3):262-277
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.

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, randomeffect 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 level and management model, promote refined management, and achieve sustainable development.

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.

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.

PACS represents the future of radiology in modern hospitals. Workstations and databases can be developed to substantially increase clinician's productivity, improve diagnostic accuracy, and make a large amount of knowledge and patient information available on-line to the physician. Currently, there are several hospitals in the process of implementing a total PACS system. They include Madigan Army Medical Center (Tacoma, Washington), VA Hosital in Baltimore, and Hammersmith Hospital in London (I) In order to provide the radiologists, the clinicians, and other health personnel in Korea with the general concept of PACS and its up-to-date status report, we describe the MDIS System being implemented in MAMC (Madigan Army Medical Center) which is the first hospital-wide large-scale PACS in the world. The major PACS components in MAMC have been installed since March 1992 and the full system implementation will be completed by summer 1993. The goal of the MDIS System in MAMC is to increase to more than 90% filmless by the end of 1993. In this paper, we discuss the introduction and background of PACS and its potential benefits, the current status of PACS installation in MAMC and the future plan, and the flow of image data and text information in MAMC.

This study was performed to suggest a new efficiency measurement indicator is necessary for evaluating management efficiency of food service operations in contract-managed foodservice companies, to distinguish efficient food service providers and inefficient ones by measuring comparative efficiency among food service operations, and to provide guidance for effective management through showing benchmarking targets for improving inefficient food service providers. The subjects of this study were the 93 B&I foodservice Operations of a domestic contract food service company. The analysis was conducted using CCR model in DEA model. A software, 'Frontier analyst', was used for the analysis. Based on the results derived from comparison of efficiency evaluation classified by providers with use of DEA, it was possible to identify efficient food providers and inefficient providers, and subsequently provide benchmarking guidelines for improvement of the inefficient groups. In analyzing the differences between the results of DEA efficiency evaluation by detailed operation status of food service providers, there was significant difference of efficiency outcomes in terms of contract types, while there was no significant difference in terms of business condition.
