Performance assessment is recognized as a proper evaluation method to integrate the teaching and learning process into the evaluation one and as an essential means to produce meaningful evaluation results. However, it has deteriorated into a teacher-centric evaluation method with the students excluded due to the cost and time issues and the heavy workload on the teachers. Those changes have affected the reliability of the assessment results. This study developed and applied a web-based performance assessment system by using Moodle, open source software, to help the teachers efficiently run performance assessment in school and the students increase their learning effects. As a result, it lifted the burden of system development from the shoulders of the teachers trying to do web-based performance assessment and solved the reliability issue raised in the old peer evaluation approach through diverse strategies offered by Moodle.

The intent of this study is to develop system dynamics model for assessment of organizational and human factors in nuclear power plant which can contribute to secure the nuclear safety. Previous studies are classified into two major approaches. One is engineering approach such as ergonomics and probability safety assessment(PSA). The other is social science approach such like sociology, organization theory and psychology. Both have contributed to find organization and human factors and to present guideline to lessen human error in NPP. But, since these methodologies assume that relationship among factors is independent they don't explain the interactions among factors or variables in NPP. To overcome these limits, we have developed system dynamics model which can show cause and effect among factors and quantify organizational and human factors. The model we developed is composed of 16 functions of job process in nuclear power, and shows interactions among various factors which affects employees' productivity and job quality. Handling variables such like degree of leadership, adjustment of number of employee, and workload in each department, users can simulate various situations in nuclear power plant in the organization side. Through simulation, user can get insight to improve safety in plants and to find managerial tools in the organization and human side. Analyzing pattern of variables, users can get knowledge of their organization structure, and understand stands of other departments or employees. Ultimately they can build learning organization to secure optimal safety in nuclear power plant.

Purpose: To identify the need to reform in the crisis response of Health Teacher, School Nurse, in elementary school during epidemic outbreak of influenza H1N1. Methods: 139 elementary health teachers, school nurse, in seoul elementary school responded in the questionnaire, and we analysed by using frequency and percent, t-test, and paired t-test. Results: The Job status became 121% more 'during influenza H1N1 (flu) outbreak' than Job status of 'before outbreak'. The proportion of the flu-related duty among their daily workload was up to 77.5%. The administration-related workload of the flu-related duty was 30.8%. and students' health assessment including temperature measurement 18.7%. Furthermore, an impediment of usual daily work due to an increaed flu-related workload was 95.7%, and no alternative plan such as disposition of assistant labor force was 86.1%. Especially, an impediment of health education was 61.0%, so the major concern was the loss of health education. We compared average scores (a five-point Likert scale) of health teachers' work motivation, exhaustion, work relationship and Job management of 'during' with 'before' flu-outbreak. The difference range of 'during' minus 'before' work motivation score was from -0.4 points to -0.9; work exhaustion range from 1.8 to 1.9; the difficulty of relationship between students, school personnel, parents of students, and health teachers from 1.4 points to 1.3 points; and the consideration of changing Job, taking time off from the Job and retirement from 1.4 to 1.6 points. Conclusion: The health teachers had a heavy workload due to flu-outbreak. They also experienced the impediment of usual work implementation. However, there was a shortage of alternative plan such as disposition of an assistant labor force. Under their Job status like this, the health teachers' motivation score was decreased and work exhaustion was increased. Furthermore, they had a lot of relation difficulty with students and school personnel. Therefore, we suggested that in contrast to the usual Job status, there is a need to have a prepared response during school crisis like flu-outbreak such as improved response system in seoul metropolitan education office, simplification or dispersion of administrative work, and temporary call-center for simple inquiries or advices.

Cytotechnologists evaluate and analyze disorders of cells that constitute the human body, and are involved in the primary assessment of diverse diseases, including cancer. However, the employment conditions and workload of cytotechnologists are poorly understood. This study was undertaken to provide basic data for establishing the criteria for quality control certification factors based on the scope of effective task performance of cytotechnologists, and to provide results of their workload analysis according to the type of medical institution. The study was conducted by enrolling certified cytotechnologists working at various nationwide medical institutions. Our analysis revealed that 178 personnel (72.7%) were involved in primary screening of samples. On an average, the daily number of primary screening of samples performed per cytotechnologist (76 respondents) was determined to be 75.4 chapters (16.8 chapters/hours) at the university hospital level, 72.4 chapters (18.6 chapters/hours) at the general hospital level, and 231 chapters (32.6 chapters/hours) at professional trust institutions. Our results indicate the necessity to establish a consultant with the Korean Cell Pathology Association, to enable finding solutions to solve existing issues by establishing accurate standard guidelines for assessing cell screening.

Purpose: This study defines a vulnerable group in a community that has become the main target of a national health project also, it is descriptive research to suggest an evidence-based direction to meet their deficit health-related needs, Method: This research examined 833 families and 1,835 family members of the financially vulnerable class that was registered in a home visiting program of a public health center. Among them, 892 persons who had health problems, and their family members were examined in detail to find out their characteristics of vulnerability and health needs by assessment during a nurses home visit. Frequency distribution, stepwise-regression and factor analysis were used to analyze the data. Result: The vulnerable group that was defined with social indexes set as standards, involved substantial characteristics of vulnerability. The characteristics of demand showed tendencies of being clustered in 5 factors needs of intensive nursing care, chronic nursing care problems and helplessness, maintenance of family functioning with a disability, deficient problem solving ability, and simple financial fragility. Conclusion: Categorization of needs is an evidence-based estimator of workload in nurse home visiting services, and can be used as a basic resource for direction to meet the deficit needs of a vulnerable group.

Purpose: This study aimed to identify the concrete educational needs of visiting nurses working in a community health setting in Korea. Methods: We conducted four focus group interviews from October 7 to October 18, 2021. Twenty-five visiting nurses who worked in public health centers were recruited through purposive sampling. A qualitative content analysis was used to analyze the interview data. Results: The demands of educational contents for visiting nurse safety management practical training were: (1) coping with physical and verbal violence, (2) coping with sexual violence, (3) infection control for infectious diseases with a high prevalence in the community, and (4) preventing and coping with animal bites during home visits. In addition, visiting nurses suggested training programs that comprised: (1) case-based learning, (2) short video clips, and (3) recurrent integrated education. Conclusion: Safety management training programs for visiting nurses should be implemented to the extent that they add no burden on their workload and are easily accessible at any time. In addition, training programs should be based on actual cases and be focused on contents that can be applied in home visit situations. A practical safety management training program should be developed based on the educational needs of visiting nurses, as identified through this study.

Touch screen phone which is expected to play a big part of the mobile market for the next few years, has many merits but demerits of inaccurate feedback. It offers audio and tactile feedback to strengthen the weak point. This study aims to see if audio feedback and vibration feedback react upon each other under realistic conditions. We had a qualitative research in perception after using touch screen phone feedback. The result showed that with any feedback users were satisfied more than without any feedback and there was diversity in response. We ran the study again to see the performance level and the projective workload between the kind of feedback and interrupting feedback environment Performance rates were faster with audio feedback and according to the projective workload assessment users felt that task was easier and less annoying with audio-vibration feedback. The results suggest that audio feedback could be more effective than vibration feedback. A future study will figure out the relationship between the factors of qualitative-controlled feedback and learning time and the performance, and the main cause to make people prefer one feedback over another in a realistic world.

Importance of the work-related musculoskeletal disorders (WMSDs) has been increasing in the hospital industry such as health care industry and financial industry. This study investigated in order to identify the factors like general, occupational and ergonomically characteristics of the subjects related to musculoskeletal disorders (MSDs) of physical therapists (PTs). Ergonomic tools of rapid upper limb assessment (RULA) were used for evaluation workload of the tasks. Prevalence of MSDs were 13 PTs (26.0%) for neck, 31 PTs (62.0%) for shoulder, 9 PTs (18.0%) for arm/elbow, 27 PTs (54.0%) for hand/wrist, 28 PTs (56.0%) for back, 14 PTs (28.0%) for leg/foot. The analysis of the rate of the pain intensity showed that 53.5% subjects experience moderate pain and 14.0% subjects experience severe pain. Factors which were general characteristics, for example, height, ergonomically characteristics such as 'Posture Score A' were related musculoskeletal subjective symptoms in logistic analysis (p<.05). Among physical therapists, action level of RULA were action level 2 (6.0%), action level 3 (52.0%), action level 4 (42.0%). Physical therapists were estimated one of the highest risk factor in this study. This study suggested that the need of preventive education and program for PTs (physical therapists). Comprehensive and systematic management plans should be established to include both ergonomic and sociopsychological aspects.
