This study establishes basic data for operations management by organizing processes and measuring time in the mini line for female jackets to improve productivity, ensure competitiveness, and maintain operator competency and the line process flow balance between apparel manufacturing companies. The results of this study are as follows. Sewing operations are divided into preparation functions, arrangement, partial tasks, and assembly that consist of 84 processes. The results from time measurement indicate that 3238.41seconds (sec) were required to produce a single jacket and that the average time required for operators was 231.32 sec. A control limit was established to increase the reliability of the measured value for net time. After outside values were removed, the operation time was measured to be 3176.35 sec. This accounted for 98.08% of the total operation time, with net time decreasing by 62.06. Skill and effort level coefficients were applied to measure the operator performance, the total real time was calculated to be 3415. The requirement for preparation and arrangement operations were 1233.35 sec, and 2182.22 sec for partial tasks and assembly operations. Process separation and organization were performed after the bottleneck operation was selected to identify the maximum line balance. Consequently, process efficiency of preparation and arrangement operations increased from 79.19% to 93.00%, and the partial tasks and assembly operations increased from 62.36% to 90.93%.

This study was conducted to offer a basic material for effective human resource management of nurses by studying correlations among inter-department rotation, job motivation and organizational commitment. For this study 159 nurses in a medical college hospital were surveyed. Organization Assessment Instrument(Van de Ven. 1980) and Organizational Commitment Questionnaire (Mowday, 1979) were used. SPSS was used to analyze the data. The results of this study are as follows : 1. Nurses who had been rotated to other departments showed higher motivation scores than those who had not. 2. Nurses who had been rotated also indicated higher organizational commitment scores than those who had not. 3. There was significant positive correlations among nurse's age, job motivation and organizational commitment of nurses. 4. There was significant positive correlations among nurse's experience, job motivation and organizational commitment of nurses. 5. Inter-department rotation times were significant positive correlation with job motivation. 6. "The sense of achievement perceived form performing one's duty" was the most important criteria that nurses consider in measuring their job motivation. As to the criteria for inter-department rotation, some respondents stated that it is needed when "current assignments are not suited for particular individuals" and such rotations would job motivation and elevate the morale of nurses involved." Many opposed using the rotations as a "means of reprimanding individuals." In conclusion, inter-department rotation has a positve effect on the nurse's job motivation and organizational commitment, so regular inter-department rotation have to be recommended to nurses who want rotation.

This study investigated the relationship between the nurse's followership, job satisfaction and organizational commitment. The sample consisted of 173 nurses of 2 private university hospitals. The instruments used in this study were the followership scale (Kelly, 1994), the job satisfaction scale (Slavitts et al., 1978), the organizational commitment questionnaire (Mowday et al., 1979) and the demographic questionnaire. SPSS/WIN program was used for descriptive statistics, ANOVA, and Pearson correlation analysis of data. The results were as follows: 1) The styles of followership were classified as pragmatist followers (73.4%), exemplary followers (19.7%), passive followers (4.6%), and alienated followers (2.3%). 2) The mean of independent/critical thinking was 3.32 (M=3.0), and active involvement was 3.04 (M=3.0). As a whole, the mean of followership was 3.18 (M=3.0), job satisfaction was 2.82 (M=2.5), and organizational commitment was 3.97 (M=3.5). 3) Significant differences were found in the degree of clinical nurses' perception of followership according to the demographic characteristics such as age, education, position, and career. 4) Significant differences were found in the degree of clinical nurses' perception of followership according to followership styles. 5) The followership was significantly related to job satisfaction and organizational commitment. In conclusion, the nurse's followership is considered as an important concept and this suggested that the concept could be used as a major variable in measuring effectiveness of nursing organization.

Background: The Functional Assessment of Chronic Illness Therapy (FACIT) for Dyspnea was developed to assess multidimensional dyspnea using two subscales (experience of dyspnea and functional limitation) and a total score. Objects: This study aimed to assess the reliability and validity of the Korean version of the FACIT-dyspnea 10-item short form questionnaire (FACIT-dyspnea-K). Methods: Subjects were 163 patients with cancer. Dyspnea-related scales (modified Medical Research Council scale [mMRC], European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 [EORTC QLQ-C30], Hospital Anxiety and Depression [HAD], and WHO Performance Scale) were used to validate the FACIT-dyspnea-K. Results: Internal consistency was confirmed by Cronbach's alpha values of 0.90 and 0.95 in factors 1 and 2, respectively. Convergence validity was determined by comparing the two factors and total score of the FACIT-dyspnea-K with conceptually related assessment tools measuring the physical and emotional effects of dyspnea, with which correlations ranged from 0.364 to 0.567. Criterion validity was established by significant differences in the FACIT-dyspnea-K score between groups when the patients were classified by performance status as assessed by the WHO performance scale. Furthermore, the FACIT-dyspnea-K showed notable correlations with other dyspnea scales (mMRC, EORTC QLQ-C30, and HAD) for cancer patients (r = 0.28 to 0.54). The test-retest reliability of the two factors and total score of the FACIT-dyspnea-K appeared to be excellent (Cronbach's alpha = 0.96 to 0.97). Conclusion: This study supports FACIT-dyspnea-K as a valid and reliable instrument to assess the dyspnea experience of cancer patients in clinical settings.
