This study aimed to investigate predictors of turnover intention of home visiting nurses at 16 public health centers in Busan. There are two groups of independent factors: non-work related(i. e., age, educational level, working duration as nurses in hospitals, and certificate), and work related factors(i. e., working duration as nurses in public health centers, working duration as home visiting nurse, position, number of households visited per week, workload, cooperation among staff, support by supervisors, supply of vehicles, and supply of materials). Data were collected with self-administrated questionnaires which consisted of 4 items of non-work related factors, 9 items of work related factors, and 1 item of turnover intention to other department. Data were analyzed using an univariate logistic regression and multiple logistic regression. According to the results, heavy workload (Yes vs No, OR=4.31, $95\%$ CI=1.16-16.04) was the most powerful predictor on the turnover intention. In conclusion. this result was similar to those of other studies on the predictors of turnover intention of clinical nurses at hospitals. To decrease the turnover intention among home visiting nurses at public health centers in Busan, alleviating the workload is needed.

Objective: The purpose of this study is to examine the effect of the childcare environment on childcare efficacy of childcare teachers. Methods: The participants in the study were 274 childcare teachers working at childcare centers. The childcare environment was divided into physical environment and the work support environment. Results: The results of this study are as follows. First, there was a significant difference in childcare efficacy depending on the age and career of the childcare teacher. Second, the childcare environment of the childcare center showed a static correlation with the childcare efficacy of the childcare teacher in both the physical environment and the work support environment. Third, the physical environment of the day care center had an affect on child care efficacy. Among the subfactors, furniture for routine care, play and learning had a significant impact. Fourth, the work support environment of the childcare center had an affect on childcare efficacy of the childcare teacher. Among the subfactors, staff interaction and cooperation, and opportunities for professional growth had a significant impact. Conclusion/Implications: In order to enhance childcare efficacy of childcare teachers, a high quality childcare environment should be established.

Purpose: The purpose of this study was to observe office workers' postural behaviors during computer work to identify the risk factors for head and thorax postural behaviors. Methods: The participants included 57 office workers who worked longer than 20 hours on a computer. Postural behaviors during computer work were measured using 3-D wearable motion sensors on the forehead and sternum. A multivariate linear regression model evaluated the association between various risk factors (neck pain, demographics, and environmental factors) and non-head and thorax postural behaviors. Results: The participants maintained their head and thorax in neutral postures (defined as 10° extension~10° flexion and 5° extension~10° flexion, respectively) for 24.7% and 39.3% of the total recorded time. Those who reported neck pain at the measurement of postural behaviors showed less time spent in thorax postures. Current neck pain, high desk height, and the distance between the keyboard and the edge of the desk (cm) were found to be related to less time spent in a neutral thorax posture. Conclusion: Office environment factors and current neck pain might affect workers' thorax postures, which might also determine the orientation of head postures during computer work.

In the modern market economy, where the consumers are increasingly seeking pleasure rather than convenience, a variety of retailers are making every effort to promote sales records. In order to achieve this goal, the division of work needs to be effectively performed and the allied enterprises need to cooperate with each other. Consequently, the Customer Relationship Management(CRM) system should be established through the research and analysis on brands and consumers. It is also necessary that the enterprises should cooperate mutually, using the PRM system which makes it possible to share the information from the CRM system. This report is going to propose a desirable cooperation which is reguaired in Retail Shop Design. And it will be done by describing the relation between CRM & PRM and the marketing based on brands and consumers.ere it examines closely the vibrating unit of the elevator and propose the countermeasure of it.

In this paper, we classify web-based social network into two types: open and community, and model user behavior in social activities. After that, we also propose the combination of instant messaging and web system as the method of support asynchronous/synchronous social activities. Furthermore, we introduce ImCoWeb prototype system that supports both asynchronous social activities (ex. social bookmark, comment, rate, and data share) and synchronous ones (ex. real-time communication, file transfer, co-browsing, and co-work). Because it is built on the existing instant messaging, it reduces costs by reusing the facilities such as session management, user management, and security of instant messaging.

This work presents field-dependent Bingham and response characteristics of MR fluids under shear and flow modes. Two different types of magneto-viscometers are designed and manufactured for the shear and flow modes. respectively. For the MR fluid to be tested, MRF-132LD of Lord co. is employed. The field-dependent yield stress is experimentally distilled at various temperatures using the magneto-viscometers. Time responses of the MR fluids to step electric fields are also evaluated under two operating modes.

The paper presents the development of separating system from the slash with solid and liquid. The materials of filter are used rice chaffs, which are widely found in the agricultural village. The performance of separator is experimentally shown through new developed measurement apparatus. The flow rates of the system are evaluated by changing the inlet pressure of slash, thickness of filter and size of particle concentration of rice chaffs. In this work the optimal design parameters can be obtained for the separator for solid and liquid. And in the results rice chaffs filter improve the performance of separator solid and liquid.

In this paper, Solidworks was used to do a conceptional design of an box of an electric saver in order to manufacture an electric saver having a different performance and model. Based on this, analysis was made considering weight concentrated on an box. 3-dimensional finite element analysis code, ANSYS was applied to obtain stress, strain and deformation in order to secure durability and these data was reflected to a detailed drawing.

In order to educate and train proper work forces who can satisfy the industry demands, Human Resource Development Korea had developed the Korean National Occupational Standards. Following to the competency-based-curriculum and the guide lines which were developed based on this standard, the training program fur a machine design has been developed. It has been applied in several colleges and some typical examples which were carried out by students as term project are presented to show the effectiveness of the developed program.
