This study was performed to review applying the case management to the occupational health nursing as a cost-effective way for injured workers. The case management for injured workers is a comprehensive management system, which is composed of planning and implementing in cooperation with employee, employee' family, medical service provider team, employer and case manager, to provide high quality health services to employee and their family. The case management process for injured workers is similar to the nursing process. It thus appears that the occupational health nurse is best personnel to perform the role of case manager for injured workers in workplace. As a case manager in workplace. the occupational health nurse would be expected to get both knowledge and experiences, to get trusted from the employee and employer, and to expand professional domain in changing health care environment.

The Risk Management (RM) is applied for managing uncertainty of project. In this circumstance, the competences of RM have a direct effect on the performance of its application. Especially, as the RM, one of the project management areas, is a peopleoriented management field, the individual behavioral competences are significant for a risk manager. Therefore, this paper describes the development of individual behavioral competences for construction project risk manager. For this, the research classifies the individual behavioral competences of RM. And, the Exploratory Factor Analysis (EFA) are applied to verify a validity of the competences. Likewise, a reliability analysis using Cronbach's alpha values is performed to test internal consistency. Based on the results, the authors carry out the Focus Group Interview (FGI) on expert panels of construction RM to confirm the hierarchical model of the individual behavioral competences. It is concluded that the proposed hierarchical model of individual behavioral competences helps construction companies to diagnose the competences of their project risk manager for progressing.

For the construction safety manager, it is expected that job stress is significantly high due to lack of expertise about new technology, new construction methods, and enlargement of scale as well as due to work intensity and unstable work hours. It is probable that such an increase in job stress not only has bad effects on individual, but also the bad effects spread to construction industry at large, resulting in rise in accident rate, increase in direct and indirect loss cost, and loss of reputation. In this context, methods for controlling construction safety manager's job stress are needed at the levels of both government and company. Therefore, this study investigated and analyzed the effects of construction safety manager's job stress on job satisfaction and job commitment, and proposed methods for relieving job stress. In addition, this study was suggested policies for higher job satisfaction and job commitment at the levels of the government and companies.

Recently, owing to performance elevation of telecommunication technology, increase of wireless internet's subscriber and diffusion of wireless device, Interest about LBS (Location Based Service) which take advantage of user's location information and can receive information in concerning with user's location is increasing rapidly. So, MOMS (Moving Object Management System) that manage user's location information is required compulsorily to provide location base service. LBS of childhood such as service to find a friend need only current location, but to provide high-quality service in connection with Data Mining, CRM, We must be able to manage location information of past. In this paper, we design distributed manage system to insert and search Moving Object in a large amount. It has been consisted of CLIM (Current Location Information Manager), PLIM (Past-Location Information Manager) and BLIM (Distributed Location Information Manager). CLIM and PLIM prove performance of searching data by using spatiotemporal-index. DLIM distribute an enormous amount of location data to various database. Thus it keeps load-balance, regulates overload and manage a huge number of location information efficiently.

Vehicle and marine navigation which are currently being commercialized provide route guidance service by specifying a fixed position as a destination. In the route guidance service of existing navigation, if the destination has to be changed in the middle, a new destination must be designated again to obtain the navigation service. However, if the destination can't be designated, it is difficult to clearly use it. In this paper, in order to overcome the difficulties of directions in the existing navigation, a new navigation specifying moving targets as the destination has been developed to get the directions. A proposed system is that a group is made and a group manager is appointed as a destination and then a user can get the route guidance based on location of the group manager. In the service way, relationship between the group manager and user is one-to-many and relationship between the user and group manager is one-to-one. The proposed technology is able to provide services that the user can easily find the moving targets such as the positioning surrogate drivers, tracking routes and location among travelers and finding children.

SNMP에서는 관리정책에 따라 Manager가 특정 Object 에 대하여 MIB 값을 Agent에 요청하고 Agent가 이에 응답하는 식으로 정보를 송수신하므로 많은 네트워크 traffic이 발생한다. 특히, Traffic의 경향분석 기능 수행시 동일 Object에 대한 반복적인 정보 송수신 발생은 매우 비효율적이다. 본 논문에서는 기존의 SNMP에 시간 기능을 수용할 수 있는 새로운 PDU를 추가하고, 이를 이용하는 Manager와 Agent간에 불필요한 정보 송수신을 최소화하면서 경향 관리 정보를 수집할 수 있는 효율적인 방안을 제시하였다. 시험 결과 구현된 SNMP는 기존 SNMP와 호환성을 유지하면서 네트워크 Traffic을 크게 감소시켰다.

This study explores the reporting tendencies of project managers when sending a status reports to their respective senior managers in information systems development project. It also examines the effect of selective reporting on report quality and systems development performance. The research model is proposed based on literature survey as well as key points from Iacovou et al. [2009] which is an extension of selective reporting in information systems project. Analysis of responses from 257 project managers in information systems industry indicates that pessimistic reporting by project managers has negative effect on both report quality (mediator variable) and systems development performance, while optimistic reporting has no significant effect on systems development performance. The CEO interest has an impact on the senior manager's power, which in turn leads to optimistic reporting by project managers. The senior manager's character has an impact on the senior manager's leadership, which in turn leads to pessimistic reporting. No direct relationship exists either between CEO interest and optimistic reporting or between senior manager's character and pessimistic reporting. In addition, trust toward the senior managers is significantly related to pessimistic reporting. Finally, report tendencies are also found to be affected by the active/passive characteristics of project managers.

This study tried to confirm the mediating effect of positive psychological capital on the relationship between the communication Competence of managers who are recognized as organizational members working in the company and the adaptive performance of the members. To this end, the research hypothesis established through the final 255 data was verified as follows using the SPSS 21.00 and AMOS 21.1 version statistical programs. First, the higher the manager's communication Competence, the higher the positive psychological capital of organizational members. Second, the higher the communication Competence of the manager, the higher the adaptive performance of the members. Third, as the positive psychological capital of organizational members improved, adaptation performance improved. Fourth, positive psychological capital showed a partial mediating effect between the manager's communication Competence and the member's adaptive performance. The results of this study empirically analyzed the relationship between manager's communication Competence and members' positive psychological capital assumption (+) on the improvement of organizational members' adaptive performance ability. This study has the meaning of the most important research in that it provides additional theoretical and practical implications in the face of insufficient research on factors affecting the adaptation performance of organizational members.
