An increasing number of hospitals are seeking for new or mixed compensation strategies to improve the productivity of their medical staff in the struggle to provide high quality medical services at low costs amid the economic hardship. To motivate physicians toward the right direction, it is necessary to effectively evaluate their performance that provides a basis for compensation. However, productivity has been historically difficult to measure, particularly for physicians in academic medical centers who are expected to engage in research, education, and patient care simultaneously. The objectives of this study were to define performance measures of physicians and clinical departments in academic medical centers. to examine correlations between the measures. and to investigate factors affecting the measures. The performance data of 212 faculty physicians in 17 clinical departments in two university teaching hospitals affiliated to one medical school during the fiscal year 1994 was used for analyses. Patient care revenue, net profit. and adjusted number of patients were defined to measure the performance in patient care. and number of articles published in academic journals and research grant were defined for research activities. Both individual physicians' performance measures and per physician measures of clinical departments were analyzed. All measures defined to evaluate individual physicians' performance were positively related to each other. Clinical department and rank of faculty position were statistically significant predictors of revenue. and hospital. clinical department. and rank were significant predictors of net profit. journal publication. and research grant. Patient care measures defined to evaluate clinical departments were related to each other. so were research measures. and no significant correlations were found between patient care measures and research measures. Also found were large differences in department. ranks when clinical departments were evaluated by absolute per physician performance measures and evaluated by annual rate of changes in performance measures. These findings suggest that departmental performance measures opposed to individual performance measures are relatively free from problems of factors affecting the performance measures that are not in control of clinical departments or individual physicians. Results from the correlation analysis of departmental performance measures indicates that measures of research performance should be included in the evaluation to promote research activities in academic medical centers.

Purpose: This study was to explore factors affecting musculoskeletal symptoms of the child care centers' teachers in Korea. Methods: This study was a descriptive research, using a cross-sectional survey. Convenience samples of 230 child care centers' teachers aged 20 to 65 were selected. A self-administered questionnaire was used to measure general characteristics, job-related characteristics, exercise habit, fatigue and musculoskeletal symptoms of the body parts. The data were analyzed with the SPSS/WIN 21.0 program. Results: Shoulder pain (73.5%), low back pain (72.6%) and wrist/hand pain (57.8%) were the most common musculoskeletal symptoms. Shoulder pain significantly differed depending on the age of children in charge at the child care center (p<.047). The exercise habit was related to low back pain (p<.028) and the career was linked to wrist/hand pain (p<.046). The logistic regression analysis revealed exercise habit and fatigue were the risk factors on musculoskeletal symptoms of many body parts. Conclusion: These results suggest that interventions targeting the child care centers' teachers should be considered job-related characteristics and fatigue in order to prevent musculoskeletal disorder. Thus, there continues to be a need to develop exercise program for the child care centers' teachers.

Objective: This study aimed to determine the effect of a teacher professional learning environment at workplace day care centers on the professionalism of beginning teachers and also to verify the mediating effects of the beginning teachers'work task motivation on that relationship. Methods: The participants were 129 new teachers currently employed at workplace day care centers. The Current Status for Professional Competence was used to measure the teachers' professionalism. The Professional Learning Environment Inventory assesses the professional learning environment of day care centers. To measure the work task motivation, the Work Tasks Motivation Scale for Teachers was used. Results: Firstly, positive relationships were identified between a professional learning environment and their intrinsic motivation and identified motivation. However, there were also negative relationships between the professional learning environment and their introjected motivation and amotivation. Secondly, this study partially verified the mediating effects of the beginning teachers'work task motivation on the relationship between the professional learning environment and teachers' professionalism. Conclusion/Implications: The relationship between the professional learning environment and the professionalism of beginning teachers was mediated by the teachers'own intrinsic motivations, identified motivations, and amotivation.

This study was aimed to validate the Infant/Toddler Environment Rating scale (ITERS). The rating scale was translated and adjusted appropriately by two researchers majoring child studies. An item-by-item comparison of the ITERS with criteria of NAEYC was conducted as the measure of content validity. 88% of the items of the ITERS was covered on the NAEYC criteria. Criterion validity was assessed by comparing ITERS scores and the Assessment Profile for early childhood Programs scores. The total correlation of two scores was .87. The sample for the inetrater reliability and internal consistency studies included 30 infant/toddler classes in 30 day care center in Inchon city. Two observers independently rated each class on the ITERS during a single visit. The Spearman's correlation coefficient for interater reliability on the overall scale was .74. For the measure of internal consistency, the Cronbach's Alpha score on the overall scale was .93. The rating results show that national/public child care centers have better quality in Adult Needs and Learning Activities subscales than private child care centers have.

When constructing a high-speed railroad, the reduction of the distance between track centers and the width of track bed will save the construction cost. However the shortening the distance between track centers may cause the stability problems due to higher wind pressure. Therefore the extensive technical review and aerodynamical study should be performed to determine the adequate distance between track centers. In this study, the impact that the increase in wind pressure due to the change of aerodynamic phenomena with the change of the distance between track centers may have on two trains passing by each other was predicted, and the stability of train operation was analyzed in order to review the distance between track centers suitable to Honam HSR trains. And we estimated the aerodynamical effects by the results of the field test.

The objective of this study is to investigate financial integrity strategies for sustainable development of local public medical centers, and particularly focus on seeking ways to enhance its financial efficiency and publicness. The data which was collected from 33 local public medical centers was analyzed by Data Envelopment Analysis to measure its financial efficiency. Then, Matrix Analysis was used to examine the association of financial efficiency and publicness of local public medical centers with related factors. In the aspects of facilities and location, according to the results, the local public medical centers which have larger number of available hospital beds or located in bigger cities were examined to have higher degree of publicness. In the aspect of human resources, greater number of doctors made both financial efficiency and the degree of publicness decreased, whereas higher participation rate of educational program for doctors affects increasing its financial efficiency and publicness. Lastly, in the aspect of costs, higher labor, material, and administrative cost diminished financial efficiency, but enhanced the degree of publicness. Based on these results, this study concluded that enhancing the publicness of local public medical centers should be pursued by increasing the accessibility with better facilities and location, and also concurrently organizing rational expenditure structure with appropriate cost investment to the resources of local public medical centers. Also, it is necessary to enhance both financial efficiency and publicness simultaneously by improving the quality of health care services through the educational programs for medical staffs.

Gravitational centers of precise spinning components must coincide with the rotational centers of those to reduce noise and vibration and to extend those lift as well. Therefore quality control should be performed in the manufacturing process, in which the unbalance moments are accurately measured. In this paper 3-point weighing method is adopted to measure the unbalance moment of small-sized precision spinning elements using electronic scales with 0.1 mg resolution. Firstly methods to eliminate the fixture error and to reduce the effects of frictional force that is known as side effect, are proposed. A measuring system is developed and various experiments are performed to verify the proposed approach. The measured and calculated values are analysed in statistical methods, and this provides the errors of the measuring system. The results show that the proposed theory and test procedures gives reliable unbalance moments and gravitational centers.

The purpose of this study was to examine the maintenance of an evaluation accreditation indicator according to child care center teachers' participation in decision making. The subjects of this study were 139 teachers from 12 accredited national, public, private, and corporate child care centers in Seoul and North Gyeongsang Province. The TIP-2 (Teacher Involvement and Participation Scale V.2) and Accreditation Indicator for Child Care Centers were used to measure teachers' participation in decision making and accreditation indicator maintenance. Frequency, mean, standard deviation, one-way ANOVA and scheffe test were used for data analyses. The results revealed that the teachers who rated middle and high level in terms of their participation in decision-making showed higher levels of maintenance of the evaluation accreditation indicator than those with low levels of participation. This finding suggests that teachers' participation in decision making is an important factor for maintaining the quality of child care centers.

In this paper, we propose a modified fuzzy clustering algorithm which can overcome the center deviation due to the Euclidean distance commonly used in fuzzy clustering. Among fuzzy clustering methods, Fuzzy C-Means (FCM) is the most well-known clustering algorithm and has been widely applied to various problems successfully. In FCM, however, cluster centers tend leaning to high density clusters because the Euclidean distance measure forces high density cluster to make more contribution to clustering result. Proposed is an enhanced algorithm which modifies the objective function of FCM by adding a center-scattering term to make centers not to be close due to the cluster density. The proposed method converges more to real centers with small number of iterations compared to FCM. All the strengths can be verified with experimental results.
