Purpose: This study aims to evaluate the risk of work-related musculoskeletal disorders (WMSDs) in 119 EMT during patient-carrying tasks using a long backboard (LBB) and a variable stretcher. Methods: Manikins were used as patients, and 45 new 119 EMT from K Fire Academy were filmed performing patient-carrying tasks on stairs. The tasks were analyzed using Ovako working posture analysis system (OWAS) and Rapid entire body assessment (REBA). Results: In using LBB, the OWAS score was Mode 3(Mean 2.37, Maximum 3), requiring as soon as possible corrective action, the REBA score was Mode 11(Mean 9.16, Maximum 11), requiring immediate improvement. In using variable stretcher, the OWAS score was Mode 1(Mean 2.33, Maximum 3), non-necessity for corrective action, the REBA score was Mode 9(Mean 8.0, Maximum 11), requiring as soon as possible. Conclusion: In conclusion, improvement was needed in one task (carrying a patient using a LBB) in the OWAS and in two tasks (carrying a patient using a LBB, carrying a patient using a variable stretcher) in the REBA. Thereby, required attention and management of WMSDs during training. In addition, it is essential to carry out objective and quantitative assessments through ergonomic analysis by occupational health professionals when designing future training programs to prevent WMSDs.

Probabilistic risk assessment (PRA) has improved its elemental technologies used for assessing external events since the Fukushima Daiichi Nuclear Power Station Accident in 2011. HRA needs to be improved for analyzing tasks performed under extreme conditions (e.g., different actors responding to external events or performing operations using portable mitigation equipment). To make these improvements, it is essential to understand plant-specific and scenario-specific conditions that affect human performance. The Nuclear Risk Research Center (NRRC) of the Central Research Institute of Electric Power Industry (CRIEPI) has developed an HRA guide that compiles qualitative analysis methods for collecting plant-specific and scenario-specific conditions that affect human performance into "narratives," reflecting the latest research trends, and models for analysis of tasks under extreme conditions.

Purpose: This study aimed to explore the essentials of psychiatric and mental health nursing by identifying the care experience of the psychiatric nurses. Methods: Eleven psychiatric nurses were recruited across five geographical areas in the Korea. Data were collected using semi-structured interviews from two focus groups, which were analyzed with an inductive content analysis. Results: Participants constructed two categories including 'nursing tasks for the client' and 'nursing tasks for the organization'. Subcategories of nursing tasks for the client are 'staying alert on crisis prevention', 'leading them to be real with eager and persistent will', 'nursing beyond role boundaries', 'tuning the needs of clients' family', 'taking journey with clients' personal life history', and 'doing invisible but recognizable nursing'. Subcategories of nursing tasks for the organization are 'working as a responsible team member', 'integrating team competencies at the center of team', and 'balancing protection and control'. Conclusion: Psychiatric nurses played professional and holistic care roles for the clients, and managerial roles for the organizations. This study provides essential data for defining psychiatric nursing and estimating the appropriate ratio of psychiatric nursing staffing.

It is essential to precisely evaluate the expected dose (collective dose) before performing high-exposure tasks in nuclear power plants because those have a high potential to cause significant radiation exposure to workers. A dose evaluation method is to design the scenarios of high-exposure tasks using computational codes, which allows for the calculation of the expected collective dose. Although these computational scenarios are useful for estimating the expected radiation dose and establishing radiation protection plans, the calculated doses may not perfectly match the actual doses that workers receive during tasks due to differences between the scenario and the actual circumstances in the radiation fields. Therefore, this study presents a methodology for calculating correction factors to improve the accuracy of dose predictions from computational scenarios. This approach aims to make the predicted collective dose before the task closer to the actual dose received by workers, thereby enhancing radiation safety for personnel performing high-exposure tasks. Additionally, these correction factors will help accurately predict doses under various working conditions in the future, contributing to minimizing radiation exposure risks for nuclear power plant workers.

산업용 실시간 시스템에서 사용되는 디지털 제어기는 상호 작용하는 주기적 태스크들로 이루어져 있다. 이러한 태스크들은 최대 수행 주기 (maximum activation periods)를 제약조건으로 가짐으로써, 요구되는 제어특성을 유지한다. 그러므로 실시간 시스템을 개발하는데 있어 필수적인 단계는 각각의 태스크에 게 자원 이용률을 최소화하면서 최대 수행 조건을 만족시킬 수 있는 고정된 주기를 할당하는 것이다.[1] 각각의 태스크간의 생산자/소비자(producer/consumer)관계를 나타내주는 태스크 그래프와 자원 요구량, 그리고 주기에 대한 범위제한이 주어진다면 주기 할당 문제는 비선형 최적화 문제가 된다. 이 논문에서는 최적해의 자원이용률의 두 배를 넘지 않는 해를 찾을 수 있는 선형 수행시간의 근사 알고리즘을 제시한다. 실험 결과에서 알 수 있듯이, 제안된 알고리즘은 대부분의 경우 최적해에 매우 근접한 해를 가지게 된다.

The purpose of this study was to examine the meaning and structure of nurses' computer using experience. To do this, we conducted a total of three interviews with 11 nurses working between the ages of 26 and 48. Interview data were interpreted using Giori method (1985) and Lincoln & Guba method (1985). As a result, 112 semantic units were derived, and then 18 sub-components were divided into 5 final components. As a result of the analysis, the computer experience that the nurses used in the hospital consisted of 'used for almost every task', 'usefulness', 'important', 'convenience', 'burden', 'anxiety', desire', simple work level', 'no problems', 'eye, muscle and movement discomfort', 'depends on task', 'more complex', 'accuracy', 'organize contents', 'simple', 'incomparable', and 'easy'. Based on the above conclusions, the nurses' experiences of using the computer in the hospital could be concluded as follows. Currently, almost all nursing jobs in hospitals are using computers. However, most of the tasks related to simple computer tasks related to the ability to use the computer was low, and because of this, the computer did not work properly, or when new programs were introduced to feel the burden and anxiety, want more systematic computer education Found. Especially, according to the career, the difference between computer and hand work was different, Nurses over 20 years said that computers can handle simple tasks that are a bit more complicated than manual tasks, whereas emotional tasks were handicapped, in the 10 to 20 years of experience, computer work was more accurate and appropriate to organize content, Nurses under 10 years were not only easy to work with computers but also have no experience in manual work, they could not compare the computer and the hand work. This study suggests that the use of computers in nurses' work is essential and that more systematic computer-based education should be provided. In addition, due to the nature of the nursing service, the professional opinions of the nurses should be reflected in the development of programs for the emotional nursing work.

Purpose: This study was conducted in order to analyze the job of school health teacher in Korea. Methods: School health teachers' roles were analyzed by DACUM job analysis. Guide of DACUM methods and workshop were directed by a DACUM job analyst. The DACUM committee identified tasks associated with each duty and completed the DACUM chart. Results: Through DACUM job analysis, the roles of school health teachers were defined; one who manages health of students and staff, and conducts health education; 11 duties and 95 tasks were identified. The committee listed required knowledge and skills, working attitude, and future trends. Emergency and common disease care were the best critical duties, followed by health education, counseling, and self-development. Conclusion: School health teacher plays the roles of nurse and health care manager, and teacher. According to the expansion of health care needs and health education, school health teachers are placed in more essential and critical areas. Their duties and tasks are various and have changed significantly, thus the School Health Act should be changed practically. The results of this study can be used in development of training programs or evaluation of the job performance of school health teachers.
