The number of fire and explosion accidents caused by pyrolysis oil and gas at waste plastic pyrolysis plants is increasing, but accident status and safety conditions have not been clearly identified. Therefore, the aim of the study was to identify the risks of the waste plastic pyrolysis process and suggest appropriate safety management measures. We collected information on 19 cases of fire and explosion accidents that occurred between 2010 and 2021 at 26 waste plastic pyrolysis plants using the Korea Occupational Safety and Health Agency (KOSHA) database and media reports. The mechanical, managerial, personnel-related, and environmental problems within a plant and problems related to government agencies and the design, manufacturing, and installation companies involved with pyrolysis equipment were analyzed using the 4Ms of Machines, Management, Man, and Media, as well as the System-Theoretic Accident Model and Processes (STAMP) methodology for seven accident cases with accident investigation reports. Study findings indicate the need for establishing legal and institutional support measures for waste plastic pyrolysis plants in order to prevent fire and explosion accidents in the pyrolysis process. In addition, ensuring safety from the design and manufacturing stages of facilities is essential, as are measures that ensure systematic operations after the installation of safety devices.

The construction industry remains serious accidents, injuries, and fatalities due to it's unique, dynamic, and temporary nature. On workplace sites, Safety pre-task planning is one of the efforts to minimize injuries and help construction personnel to identify potential hazards. However, the working conditions are complicated. Many activities, including tasks or job steps, are executing at the same time and place. It may lead to an increase in the risks from simultaneous tasks. This paper contributes to addressing this issue by introducing a safety risk interaction analyzing framework. To accomplish this objective, accident reports of the Occupational Safety and Health Administration (OSHA) are investigated. The pairs of task incompatibility, which have time-space conflicts and lead to incidents, are found. Ontology technology is applied to build the risk database, in which the information is acquired, structuralized. The proposed system is expected to improve pre-task planning efficiency and relieve the burdens encountered by safety managers. A user scenario is also discussed to demonstrate how the ontology supports pre-task planning in practice.

With recent emphasis on evidence based medicine, clinical practice guidelines are seen as a potential mechanism by which unify various managerial and professional approaches to improving the quality of care. The development process of guidelines has been the subject of much research. and it is need translating the medical evidence of research into a clinical practice guidelines. the gathered evidence needs to be interpreted into a clinical, public health, policy, or payment context. The term 'clinical practice guidelines' can evoke a diverse range of responses from healthcare personnel. Clinical practice guidelines are increasingly used in patient management but some clinicians are not familiar with their origin or appropriate applications. Understanding the limitations as well as benefits of CPG could enable clinicians to have clearer view of the place of guidelines in every practice. In the context of increasing complaints and litigation in healthcare, the legal implications of clinical practice guidelines are of increasing importance. Clinical practice guidelines could, in theory, influence the manner in which the courts establish negligence by suggesting the doctor breached the duty of care by failing to provide the required standard of medical care. In several studies, the CPGs were relevent to and played a pivotal role in the proof of negligence. Much depends on the quality of guidelines and the tools developed and the authoritativeness of a guideline. Recently, there are several opinions the court also should review the validity and reliability of expert testimony including medical evidence. and widespread use of guidelines in malpractice lawsuit could lead the physicians to greater compliance with guidelines in the long term. In conclusion, Health care reformers, physicians as well as guidelines developers should understand that guidelines have both medical and legal aspects as a double-edges sword. so clinicians, legal representatives and decision-makers should not defer unduly to guidelines.

Background : As parking problem caused by increasing owner-driver and patients concentrating to a general hospital is becoming one of the dissatisfactions in medical care. It is time that a general hospital should solve the parking problem in a desirable way. The purpose of this survey is to let the clients understand the basic motivation of the pay parking and develop the better parking system. Methods : Clients of a tertiary care hospital in Chon-ju were surveyed by means of a questionnaire. All in all, 193 subjects answered the questionnaire. Results : In relation to previous experiences, 39.6% of the subjects experienced inconvenience with confused parking lot and the shortage of parking space. Under the current parking system, the subjects who felt the available parking space was enough were more than those who didn't 62.7% of the subjects answered that they could find the parking lot easily. 33.2% of the subjects mentioned that it was not easy to drive in the parking area ; The reasons were pointed out the shortage of space, disordered parking, and insufficient guide. 12.8% of the subjects satisfied with the current administering system of parking lot. The outpatients were more affirmative than the admitted patients about the charging system. As for the parking fee, 64% of the subjects answered that it is expensive, and 89.5% of the subjects thought imposing of parking fee is irrational. Conclusion : To say as a whole, the basic purpose of the charging system are more or less accepted. However, the management details like parking facilities and payment method are dissatisfactory, so it is necessary to improve the management system. It is also noted that the inpatients showed more negative attitude than the outpatients with the charging system. To secure a more convenient parking, the parking system should be considered in relation to the information service, kind guidance, improve facilities, personnel cooperation, fix outpatient scheduling system, etc.

This study was designed to investigate the impact of a 12-week nutrition education program on 32 male industrial workers (average age: $44.5{\pm}3.8$ yrs, work duration period: $20.1{\pm}5.6$ yrs) diagnosed as having dyslipidemia in a medical checkup at their workplace. This program was implemented with a conceptual framework on strengthening self-efficacy for the improvement of the health conditions of the workers. Most of all, the study exhibited benefits in the industrial workers by ameliorating the risk factors associated with dyslipidemia via changes in dietary behaviors, nutritional knowledge, and attitudes, as well as anthropometric and biochemical parameters. After the nutrition education, overall lifestyle, including the ratios of smoking (P<0.05) and drinking (P<0.01), significantly improved. Exactly 65.6% of the subjects reported that their dietary habits changed. Body weight, BMI, percentage of body fat, and waist circumference all significantly decreased (P<0.001). The systolic (P<0.01) as well as diastolic blood pressures (P<0.001) decreased. Moreover, the degree of increase in serum HDL-cholesterol was appreciable (P<0.001), and the atherogenic index also decreased (P<0.01). Further, risk factors related to metabolic syndrome in subjects significantly decreased (P<0.001). The average scores for nutrition knowledge increased from 9.3 to 17.7 points (P<0.001). All of the participants agreed on the need for a nutrition education program at their workplace. Further, it should be pointed out that the participants strongly indicated the need for continuing nutrition intervention.

Purpose: The purpose of this study was to investigate work performance and calling as determinants of job satisfaction among nurse midwives. Methods: The participants of this study were registered nurse midwives who had worked in the delivery room for more than 6 months. Data were collected by face-to-face interviews, postal mail, and mobile devices. Subjects completed self-report questionnaires from July to August 2017. The dataset was analyzed using descriptive statistics, the independent t-test, analysis of variance, the Pearson correlation coefficient, and multiple regression. Results: The mean score for job satisfaction was 3.42±0.45. Among the sub-factors, income had the lowest score (2.67±0.72) and management of delivery had the highest score (3.81±0.66). Job satisfaction was significantly different according to marital status (t=2.25, p=.028), residential area (t=2.43, p=.016), and cause of job satisfaction (F=4.54, p=.012). Job satisfaction showed a significant positive correlation with work performance (r=.29, p<.001) and calling (r=.57, p<.001). The correlation between work performance and calling was also positive and statistically significant (r=.32, p<.001). Purpose and meaning (β=.48, p<.001) and marital status (β=-.15, p=.025) significantly influenced job satisfaction. The model developed in this study explained 45% of variation in job satisfaction. Conclusion: Nurse midwives' job satisfaction may be enhanced by entrusting them with professional roles and tasks. Above all, it is necessary to develop and provide programs that help nurse midwives connect their jobs with the meaning and purpose of their lives.

Background: Medication errors are common but most often preventable events in any health care setup. Studies on medication errors involving chemotherapeutic drugs are limited. Objective: We studied three aspects of medication errors - prescription, transcription and administration errors in 500 cancer patients who received ambulatory cancer chemotherapy at a resource limited setting government hospital attached cancer centre in South India. The frequency of medication errors, their types and the possible reasons for their occurrence were analysed. Design and Methods: Cross-sectional study using direct observation and chart review in anmbulatory day care unit of a Regional Cancer Centre in South India. Prescription charts of 500 patients during a three month time period were studied and errors analysed. Transcription errors were estimated from the nurses records for these 500 patients who were prescribed anticancer medications or premedication to be administered in the day care centre, direct observations were made during drug administration and administration errors analysed. Medical oncologists prescribing anticancer medications and nurses administering medications also participated. Results: A total of 500 patient observations were made and 41.6% medication errors were detected. Among the total observed errors, 114 (54.8%) were prescription errors, 51(24.5%) were transcribing errors and 43 (20.7%) were administration errors. The majority of the prescription errors were due to missing information (45.5%) and administration errors were mainly due to errors in drug reconstitution (55.8%). There were no life threatening events during the observation period since most of the errors were either intercepted before reaching the patient or were trivial. Conclusions: A high rate of potentially harmful medication errors were intercepted at the ambulatory day care unit of our regional cancer centre. Suggestions have been made to reduce errors in the future by adoption of computerised prescriptions and periodic sensitisation of the responsible health personnel.

Purpose: This study compared nursing frequency, nursing time, and nursing intervention priorities depending on the method of neonatal induced hypothermia. Methods: We observed 15 neonatal subjects receiving therapeutic hypothermia for 3 days each. Forty-five nurses experienced with nursing neonatal patients under therapeutic hypothermia provided responses about nursing intervention priorities. Analyses with the chi-square, the Fisher exact test, the paired t-test, the Wilcoxon signed rank test, and the Wilcoxon rank-sum test were performed on the data using SAS version 9.4. Results: The frequency of nursing activities was higher for selective head therapeutic hypothermia (SHTH) than for systemic therapeutic hypothermia (STH), and nursing time was also significantly longer. In terms of nursing intervention priorities, there were priority differences in "risk for ineffective thermoregulation" and "risks for impaired skin integrity" for SHTH compared to STH. Conclusion: Since SHTH for neonatal therapeutic hypothermia requires more nursing time and frequent nursing activities than STH, STH is therefore recommended if the therapeutic efficacy is similar. Appropriate nursing personnel should be allocated for neonatal SHTH nursing. Nurses should be aware of nursing interventions for therapeutic hypothermia as the priorities are different for different methods of neonatal therapeutic hypothermia.

Purpose: This study identified the influence of hotel workers' emotional labor and social support on their intentions to change jobs. Methods: Study participants were 437 workers from seven hotels in Korea who consented to the survey. Among them, insufficient responses from 21 participants were excluded, as well as 107 responses from workers with workloads of under one hour of face to face work. Thus, 309 hotel workers were included in the final analysis. A multivariate regression analysis was used to identify factors influencing the hotel workers' intention to change jobs. Results: The intention to change jobs was high when external behavior was shown, and workers who received social support from a superior exhibited low intention of changing jobs. Conclusion: The study results show that the most influential variables of turnover intention are external behavior and the support of a superior. It is therefore important to educate managers on personnel management methods for reducing external behaviors so that the rate of job changes by hotel workers can be reduced. It is also necessary to prepare and manage measures for strengthening the support system by workplace superiors.
