When a social scientist prepares to conduct a survey, he/she faces the problem of deciding an appropriate sample size. Sample size is closely connected with cost, time, and the precision of the sample estimate. It is thus important to choose a size appropriate for the survey, but this may be difficult for survey researchers not skilled in a sampling theory. In this study we propose a method to determine a sample size under certain assumptions when the quantity of interest is measured by a Likert scale.

This study was conducted to survey of the musculoskeletal disorders of radiological technologists and prevalence rate survey tool of musculoskeletal symptoms targeting the radiological technologists working currently in hospitals or clinics. For this study, survey was conducted from July 10th, 2011 to July 31st, 2011 for about 20 days with subject of radiological technologists in private clinics, hospitals, general hospitals and University hospitals. The main results of this study are as follows : First, frequency analysis on presence of musculoskeletal symptoms in each part of body showed that neck area was 22.5 %, shoulder area was 33.1 %, arm / elbow area was 8.3 %, hand / wrist / finger area was 15.5 %, waist area was 32.4 %, leg / foot area was 16.9% (p<0.05). Second, the results from summarizing the descriptive statistics of job stress, psychosocial stress and fatigue showed that the average of job stress was 2.48 out of Likert 4 points scale, the average of psychosocial stress was 2.27 out of Likert 4 points scale. Job stress was a little bit higher than the psychosocial stress. In case of fatigue, the average was 4.57 out of Likert 7 points scale and it was a slightly higher than 'normal' (p<0.05). In conclusion, we hope this study will be helpful to systematically and efficiently manage the resources as the basic material upon deploying the preventive measures about the musculoskeletal disorders of radiological technologists in the future.

This study aims to contribute to managing the human resource of dental hygienists and qualitatively enhancing dental medical services by examining factors that affect their turnover intention. Therefore, it attempted to examine their degrees of emotional labor, job satisfaction, and social support and the effects of each variable on turnover intention. This study administered self-reporting questionnaires to dental hygienists working in dental hospitals, dental clinics, and general or university hospitals in Seoul Metropolis and Gyeonggi-do by conducting convenience sampling, from May 18, 2017 to August 4, 2017. Among a total of 224 copies that were distributed, a total of 223 copies, excluding 1 copy with poor responses, were used in the data analysis. The research tools comprised 12 questions on general characteristics, 24 questions on emotional labor (4-point Likert scale), 16 questions on job satisfaction (5-point Likert scale), 8 questions on social support (4-point Likert scale), and 4 questions on turnover (5-point Likert scale). The scores of dental hygienists were as follows: emotional labor, 2.49 out of 4; job satisfaction, 3.14 out of 5; social support, 3.04 out of 4; and turnover intention, 3.07 out of 5. Their turnover intention has a positive correlation with emotional labor, but a negative correlation with job satisfaction and social support. It was found that some factors that significantly influence turnover intention included the amount of overtime work and job satisfaction. Thus, dental medical institutes should search for measures, including improvement of the working environment, to reduce the amount of overtime work and enhance job satisfaction.
