This convergent study aimed to verify the mediating effect of organizational silence and manager's inclination to reject negative feedback in the relationship between organizational justice and turnover intention of Clinical Nurses. Participants were 250 nurses working at general hospitals with 300 hospital beds or more. Examination of the mediating effect of organizational silence showed a mediating effect of acquiescent silence when procedural justice affected turnover intention. Additionally, when interactional justice affected turnover intention, prosocial and acquiescent silence mediated it. Examining the moderated mediating effect of manager's inclination to reject negative feedback showed moderated mediation effect when procedural justice mediated the acquiescent silence and affected the turnover intention. Interactional justice had a moderated mediating effect when the mediation between prosocial and acquiescent silence affected turnover intention. Therefore, it is necessary to efficiently regulate the manager's inclination to reject negative feedback when organizational justice affects organizational silence and turnover intention.

Using chemical vapor deposition(CVD), the synthesis of graphene was performed on poly and single crystalline Cu substrates. The growth behavior of graphene and its characterization were shown utilizing the optical microscopic image and its image analysis. As a result in the analysis of graphene growth, it was found out the graphene is growing always in particular direction in relation to the crystalline direction of a single grain in polycrystalline Cu substrate. With the image analysis it was possible to show the characterization of graphene, such as the growth direction and the number of layers showing single, double and triple layers, within the neighboring single grains in polycrystalline Cu. In addition, the relatively large area of graphene with about $3mm^2$ on Cu(111) having high quality, single layer, and single crystalline was shown along with its characterization.

This study aims to develop DEA model which can look into budget cost variance analysis tool based on standard cost using 68 hospital's input and output data. For accomplishing this purpose, by introducing new DEA model which can get an attainable target cost, we can decompose an actual cost difference into several meaningful sub variances. Also based on the 2008 general hospital data, this model can make variance analysis between actual cost and target cost. Total variance can be divided into technical inefficiency variance, price inefficiency variance, allocation inefficiency variance. This study introduces that by using target budget cost concept, traditional actual cost variance can be divided into a technical variance, price variance, budget variance. Finally, we can get result which confirms there does not exist favorable size effects on efficiency and cost management in running a general hospital.

This study is a descriptive study comparing the nursing work environment, job stress and turnover intention of pediatric ward nurses and general ward nurses. The subjects of this study were 174 nurses with more than one year of experience working in small hospitals, general hospitals and university hospitals with more than 200 beds in G-city. Data collection was conducted from August 2016 using structured questionnaires to measure nursing work environment, job stress and turnover intentions. Results: There were no significant differences in nursing work environment between pediatric ward nurses and general ward nurses, and there were significant differences in job stress. Especially, the more nursing work environment of pediatric ward nurses was, the higher the job stress, the higher the turnover intention. In other words, pediatric ward nurses are more likely to have higher job stress than regular ward nurses because they are stressed not only from the health problems of the child but also from the family members. Therefore, communication and self-achievement that can reduce the job stress of the pediatric ward nurse and a variety of measures are needed.

In order to analyze the variation in length of stay(LOS) of injury inpatients, we developed severity-adjusted LOS model using Korean National Discharge In-depth Injury Survey data of Center for Disease Control. Appling this model, we calculated predicted values and, after standardizing LOS using the differences from the actual values, analyzed the variation in LOS. Major factors affecting severity-adjusted LOS of injury inpatients were found to be severity, surgery(or no surgery), age, injury mechanism and channel of hospitalization. Result of analysis of the differences between the actual values and predicted values adjusted by decision tree model suggested that there were statistically significant differences by hospital size(number of beds), type of insurance and location of institution. In order to reduce the variation in LOS, efforts should be exerted in developing nationwide treatment protocol, inducing medical institutions to utilize it, and furthermore systematically evaluating it to reduce the variation continually.

The purpose of this study was to analyze regional medical utilization variation of hospital inpatients and to suggest policy for the allocation of medical service in Korea. We analyzed the relationship among medical service, city size, income level and regional medical utilization variation of hospital inpatients. The patient survey report of 2005 year in Ministry of Health and Welfare was used for this study. To adjust on the factor age and sex, we used direct standardization method. Findings of the research were summarized as follows ; First, standardization discharge rate on patient was different in the district. city type, and number of beds. Second, standardization length of stay of patient was different in region, city type, and number of beds.

This study aimed at (a) examining the effects of teamwork, demonstrating with other nurses at a care unit on nurses' job satisfaction and self-efficacy, and (b) identifying if there is the mediating effect of self-efficacy on the relationship between teamwork and job satisfaction at a hospital. A descriptive study was conducted with a sample of 304 nurses, who were caring for patients with more than one nurse at a university hospital located in Southern area of Korea. The degree of teamwork demonstraing by registered nurses was 3.78(${\pm}0.59$) in the range from 1 to 5. Teamwork at caring units affected significantly nurses' job satisfaction(F=58.26, p<.001), and explained 42.80% in the variance of job satisfaction. The degree of self-efficacy that nurses perceived played as a mediator on the relationship between teamwork and job satisfaction at significant level(Z=5.25, p<.001).

This study is a descriptive research of investigating the correlation between new nurses' nursing performance, emotional intelligence, self-resiliency and core self-evaluation. The subjects were 114 new nurses working for less than 12 months at two different hospitals with over 800 beds located in Gyeonggi-do. Between July and November, this study collected the data measured by using a structured questionnaire survey for nursing performance, emotional intelligence, self-resiliency and core self-evaluation. As a result, it was found that there was a difference in the degree of nursing performance according to new nurses' education level, job satisfaction, and working position task satisfaction, and that the higher the emotional intelligence, self-resiliency and core self-evaluation were, the better the nursing performance was. As for emotional intelligence, education level, core self-evaluation and job satisfaction, it was found that they were variables to well predict the degree of nursing performance, and explained 33% of variance in nursing performance. Accordingly, it is necessary to provide actual field-adaptive training education including emotional intelligence and core self-evaluation other than nursing performance from new nurses' orientation in consideration of education degree and job satisfaction.

e-Science Service Integration Workbench is the core tool that enables IT-based computation and engineering researchers to collaborate their research activities via data sharing, by semi-automatically supporting the activities. Workbench provides the researchers with a scientific workflow by establishing the environment that is capable of finding, registering, composing, and executing services-legacy codes wrapped with grid services or web services-they need to use. In other words, designing their scientific workflow through the workbench, they can receive or share its final result with their collegues by submitting jobs they describe to computational resources such as supercomputers or grids or requesting an experiment. In this paper, we propose an implementation architecture of e-Science Service Integration Workbench to support grid services of Grid Middleware.
