Purpose: This study was conducted to provide baseline data to develop work patterns for nurses that are suitable to Korean hospitals. Shift work patterns and nurses' preferences for working condition were examined. Methods: Questionnaires for nurse departments and nurses were mailed to 478 hospitals from June 1 to July 30, 2012. Nurse departments of 174 hospitals and 1,409 nurses responded to the questionnaire. Data were analyzed using SPSS statistical program. Results: Of the nurses, 89.4% were working three shifts. Of the hospitals, 17.3% had implemented fixed night work. Although 80% of nurses preferred fixed time work, only 24.9% of hospitals had fixed working hours. Of the nurses, 57% agreed with night work as fixed but potential night nurses accounted for only 17% of the respondents. Sixty-three percent of the nurses agreed on short time work during busy hours. There were preference differences according to age, marital status and clinical career. Conclusion: As many nurses reported a preference for various flexible working patterns rather than three shift work, there is a need for new decisions on hospital policy to ensure improved working conditions for nurses and enhanced job security. Legal requirements also need to be considered for various work patterns.

As Indonesia determines to increase its marine fishery production, the development of tradi-tional boatyards has to be included in the agenda as it will give the local fishing communities a better chance to compete with large capital intensive fishing companies. It will also spread job opportunities evenly throughout the country instead of concentration fishing vessel con- struction in a few large shipyards located primarily on the highly populated island of Java. However development every single boatyard in indonesia would not only be prohibitively ex-pensive, but it would also create social tensions as the introduced technology would not be immediately accepted by the rural societies whose own traditions are still culturally signif-icant. Both these problems can be reduced by developing a collaborative scheme between traditional boatyards and a larger shipyard. The shipyard, with modern facilities, can develop work packages containing knock down components which are then assembled in the tradi-tional boatyards. The work packages are planned and designed so that every component can be assembled with relatively simple tools. Radical changes can be avoided as new techniques can be introduced gradually, responding to the boatyard\\`s own requirements and aspirations. While this manufacturing procedure is conceptually straightforward its efficient implemen-tation is in practice complicated by the fact that each traditional boatyard has unique char-acteristics in terms of labour resources, technological capability, and transportation links. By developing a computer model to simulate the interaction between the main shipyard and small traditional a computer model to simulate the interaction between the main shipyard and small traditional boatyards work packages can be designed that ensure that activities at all manufacturing locations are efficient.

Purpose: The purpose for this study was to identify the present working status and tasks of nurse administrators in response to requirements of expanding nurses' roles in hospitals. Methods: The design of the study was descriptive-exploratory. The participants were 338 registered nurses who were working in hospital administrative departments. The data were collected from January 17, to March 20, 2011, and analyzed with descriptive statistics. Results: The majority of nurse administrators worked in quality assurance departments while no nurse administrators assigned in finance/taxation departments. Duties of nurse administrators were developed as 117 tasks in 11 divisions. Conclusion: These results suggest that expanding nurses' roles require developing job descriptions, nursing curricula emphasizing hospital administration, positive relationships with other health professions and a supportive system.

The printing process can have to print various colors with a limited capacity of printing facility such as ink containers that are needed cleaning to change color. In each container, cleaning time exists to assign corresponding inks, and it is considered as the setup cost required to reduce the increasing productivity. The existing manual method, which is based on the worker's experience or intuition, is difficult to respond to the diversification of color requirements, mathematical modeling and algorithms are suggested for efficient scheduling. In this study, we propose a new type of scheduling problem for the printing process. First, we suggest a mathematical model that optimizes the color assignment and scheduling. Although the suggested model guarantees global optimality, it needs a lot of computational time to solve. Thus, we decompose the original problem into sequencing orders and allocating ink problems. An approximate function is used to compute the job scheduling, and local search heuristic based on 2-opt algorithm is suggested for reducing computational time. In order to verify the effectiveness of our method, we compared the algorithms' performance. The results show that the suggested decomposition structure can find acceptable solutions within a reasonable time. Also, we present schematized results for field application.

Background: In the United States, the dairy product manufacturing industry has consistently had higher rates of work-related nonfatal injuries and illnesses compared to the national average for industries in all sectors. The selection and implementation of appropriate safety performance indicators are important aspect of reducing risk within safety management systems. This study examined the leading safety indicators implemented in the dairy product-manufacturing sector (NAICS 3115) and their perceived effectiveness in reducing work-related injuries. Methods: Perceptions were collected from individuals with safety responsibilities in the dairy product manufacturing facilities. OSHA Incident Rate (OIR) and Days away, restricted and transferred (DART) rates from 2013 to 2018 were analyzed. Results: The perceived most effective leading were safety observations, stop work authority, near miss reporting, safety audits, preventative maintenance, safety inspections, safety training attendance, and job hazard analysis/safety analysis, respectively. The 6-year trend analysis showed that those implementing all eight top indicators had a slightly lower rates than those that did not implement all eight. Production focused mentality, poor training, and lack of management commitment were perceived as the leading causes of injuries in this industry. Conclusion: Collecting leading indicators with the unique interest to meet the regulatory requirements and to document the management system without the actual goal of using them as input to improve the system most probably will not lead to an effective reduction of negative safety outcomes. For leading indicators to be effective, they should be properly selected, executed, periodically evaluated and actions are taken when necessary.

This study investigated small and medium-sized hospital workers' knowledge of COVID-19, the infection-control-related fatigue and stress levels, and the factors that impacted their performance during the COVID-19 pandemic. Using a cross-sectional design, data were collected from 137 hospital workers from four small and medium-sized hospitals in S and C cities. Data were analyzed using descriptive statistics, a t-test, analysis of variance(ANOVA), Pearson's correlation coefficient, and multiple linear regression analysis. Small and medium-sized hospital workers' knowledge of COVID-19 revealed a correct answer rate of 66%. An average of 3.00 points out of 4 for infection control performance and 3.32 and 3.17 points out of 5 for infection-control-related fatigue and stress, respectively, were found. The level of knowledge regarding COVID-19 significantly differed by age and marriage (p<0.05), while infection control performance significantly differed by age, marriage, and infection control education experience (p<0.05). Infection-control-related fatigue and stress differed depending on the COVID-19 control education experience, economic and social prejudice, and fear of discrimination. There were positive correlations between knowledge and infection control performance, and infection control performance and infection-control-related fatigue and stress (p<0.001). This study showed that the factors that affected small and medium-sized hospital workers' performance included knowledge of "environmental management," "difficulties due to new role requirements," "presence or absence of infection education experience," "job type," and "age." These results suggest that practical and detailed education programs should be systematically developed and implemented for effective infection control.

Background: In modern society, rapid changes in the medical environment have required medical staff to access various information and be competent in active and effective problem-solving through collegial interactions. In line with these changes, universities are aiming to connect education. This study aimed to provide basic data of connected-convergence education by survey the awareness and needs of college students in health-related fields. Methods: This study included 122 college students from the health field. A survey regarding "the awareness and need of connected-convergence education" was conducted and general characteristics of the participants were collected from June to July 2022. Results: The awareness of connected-convergence education was low at 19.7%, but the intention to participate was high at 74.6%. Subject requirements were 18.0% for medical psychology, 13.5% for communication and counseling, 13.5% for medical artificial intelligence technology convergence, and 10.4% for sports health management. In the group showing high satisfaction with the major curriculum, the demand for connected education was also high. For efficient operation, it was investigated that it was necessary to secure specialized training courses, recognition of liberal arts credits, the right to register for courses equal to those of major students, and secure dedicated classrooms. Conclusion: Although the awareness and experience of connected-convergence education among the participants were low, the intention to participate was high. As such a plan to revitalize the university curriculum was required. It is timely to discuss the nurturing of convergence-type talents and multidisciplinary thinking skills. It is meaningful to provide basic data necessary for connected-convergence education in health-related fields at university. Universities should strive to enhance job competency in the health field by providing connected-convergence education based on student demands.
