Purpose: The purpose of the study was to understand and describe the team manager's experience in relation to the team system in the hospital organization. Methods: In-depth individual interviews for collection of data were conducted from October to November 2011. Participants were chosen purposely among team managers who had worked as team managers under the team manager system in Seoul for more than three years. Content of all interviews was recorded and transcribed according to information collected by interviewers. Data were analyzed using Colaizzi's analysis. Results: Six categories were derived from the analysis: 1) Strengthening of team manager's authority; 2) Sharing of multifaceted leadership role; 3) Demonstrating people-oriented leadership; 4) Complete interpersonal relationship and communication; 5) Self-empowering with web-like plans and practices; and 6) Going through rigorous commitment for team performance. Conclusion: Results of the study demonstrate various positive factors in association with the team system in spite of the short period of time since its introduction in the hospital organization; however, some negative aspects of the team system need to be reevaluated.

Purpose: This study was conducted to determine the effect of the performance of Workplace Health Manager at the workplace on presenteeism in the workers. Methods: Three months before this study, between June 2010 and September 2010, a self-reporting survey of 316 employees in 136 workplaces in each of each hired a Workplace Health Manager was performed at their workplace with explanations of the purpose and methods of this study after their consent was obtained. Results: The average performance score of the Workplace Health Manager as graded by the employees was 3.8 out of 5 points. The duties of the Workplace Health Manager which received higher grades were posting of the Material Safety Data Sheets (MSDS), health education, and future management with respect to the results and procedure of health care-related work. According to the employees' survey, the score for presenteeism was evaluated as 14.3 out of 30 points. Based on the presenteeism analysis results, when (1) the employee was a male, (2) the workplace was established and managed by Industry Safety and Health Committee, (3) the employees were aware of the role of Workplace Health Managers, and (4) Workplace Health Manager fulfilled his/her role actively and successfully, presenteeism was observed to a lesser extent. Conclusion: According to the results of the study, presenteeism was observed to a lesser extent when the Workplace Health Manager actively performed his/her role.

Purpose: The Purpose of the study was to suggest how the health manager use to be easy return-to-work of injured workers. Method: The data were collected by the health managers working at the 103 companies over medium size in Incheon, Gyoung-gi and Seoul through interview and report by themselves and analyzed by SAS V8 through t-test. Result: 1. The health managers are consisted of 2 kinds, one is health manager such as physician(10%) or nurse(81%) and the other is safety manager. The former works at the manufacturing company(62.9%), the latter at the service one(42.4%). 2. Management and counseling of occupational and non-occupational diseases, and high risk workers, health education, emergency care, worksite rounding, guidance of personal protector use, and health promotion services were highly performed by health managers. Comparing to these, safety managers performed guidance of job safety, safety management. The difference of two kinds of manager was significant statistically not only the aspect of general job but also related job to the workers of return-to-work after accident. Conclusion: This result shows that health manager can function as a care manager to the workers after return-to-work for adaptation to their job and rehabilitation bio-psycho-socially. But health managers don't have any regulations of encouraging injured workers to get their job again officially.

This study analyzed the effect of manager's ability on compensation policy (compensation level and performance-reward sensitivity). To this end, the final 14,150 company-year data were used for KOSPI and KOSDAQ listed companies excluding the financial industry from 2012 to 2019. As a result of the empirical analysis, the higher the manager's ability, the higher the next reward level (the manager's ability hypothesis), but the performance-reward sensitivity decreased. This confirms the manager ability hypothesis through a positive (+) relationship between manager ability and compensation, and means that high compensation for manager ability may be additional compensation for manager ability other than performance, rather than due to performance. This study differs from previous studies and has contributions in that it examines the more complex effects of managerial ability and compensation system.

This paper presents the development of intelligent performance management of computer communication networks for larger-scale integrated systems and the demonstration of its efficacy using computer simula- tion. The innermost core of the performance management is based on fuzzy set theory. This fuzzy perfor- mance manager has learning ability by using principles of neuro-fuzzy model, neuralnetwork, genetic algo- rithm(GA). Two types of performance managers are described in this paper. One is the Neuro-Fuzzy Per- formance Manager(NFPM) of which learning ability is based on the conventional gradient method, and the other is GA-based Neuro-Fuzzy Performance Manager(GNFPM)with its learning ability based on a genetic algorithm. These performance managers have been evaluated via discrete event simulation of a computer network.

This paper focuses on development of a performance manager for IEEE 802.4 token bus networks to serve large-scale integrated systems. In order to construct the management algorithm, the principles of fuzzy logic, genetic algorithm, and neural network have been combined to represent human knowledge and to imitate of human inference mechanism. Through the simulation experiments, it is shown that the proposed performance manager is capable of improving the network performance without a priori knowledge.

A spatial index is necessary to support an efficient search in a geographical information system (GIS) that is important in these days. In this paper, we design and implement a geographical data manager, called GOOD (Geo-object Oriented Data Manager) 2.0, by extending GOOD 1.0 with a spatial index processing module. That is, R-tree and R*-tree are used as a spatial index in this paper to make an efficient search possible. In addition, this paper conducts a performance evaluation to measure the improvement in search efficiency and analyzes the results of the performance evaluation. When the performance evaluation is carried out, we consider various environment factors to allow an GIS administrator to use the results as a basic data in selecting an appropriate spatial index.

Companies are building and utilizing their own data analysis systems according to business characteristics in the distributed cloud. However, as businesses and data types become more complex and diverse, the demand for more efficient analytics has increased. In response to these demands, in this paper, we propose an unsupervised learning-based data analysis agent to which reinforcement learning is applied for effective data analysis. The proposal agent consists of reinforcement learning processing manager and unsupervised learning manager modules. These two modules configure an agent with k-means clustering on multiple nodes and then perform distributed training on multiple data sets. This enables data analysis in a relatively short time compared to conventional systems that perform analysis of large-scale data in one batch.

The purpose of this article is to analyze the structure and characteristics of the care manager systems of the long term care insurance in Japan's social welfare institution. In order to realize such purposes, this paper develops the discussion process as follows. Firstly, this paper examines the developmental processes and contents of the long term care insurance system and the care plan services which are the services to aid the utilization of long term care services. Secondly, this paper describes the care manager which conducts the role of care plan services intentively. Thirdly, this paper makes the research framework which is formulated as the legislative views about the care manager on the long term care insurance act, task systems, recruitment and retraining systems, and research data of care manager. Summarizing the contents of care manager's circumstances and characteristics about the long term care insurance, the results are explained as follows. that is to define care manager's status as the components of care plan center, to control indirectly the activities of care manager's care plan by operating care service center and care plan center in equal corporate, to set role and task ambiguously, to recognize care manager's role as the attributed role of care service center, to give licence and qualification in local government. Therefore, it's difficult to realize care plan depending on speciality and neutrality for the service user. The essential parts for the reform of care manager systems may be to separate care service center and care plan center and to redefine the task and role of care manager, the role and task of which should be put on care plan services.

Recently, although there are strong requirements to manage multimedia data, there are a few researches on efficient storage and retrieval of multimedia data. In this paper, we design an object storage engine which can store and retrieve various multimedia objects efficiently. For this, we design an object manager for storing a variety of multimedia data and an inverted file manager for indexing unformatted text objects. In addition, we implement the objects storage engine which can support concurrency control and recovery schemes of DBMS by integrating the object manager and the inverted file manager with the SHORE low-level storage system. Finally, we develope a TIROS(Thesis Information Retrieval using Object Storage engine) system in order to verify the usefulness of our object storage engine.
