The role of Community Health Practitioner(CHP) should be continuously adapted to the social changes and the needs for health care services. That is the reason CHP needs to be retrained through the continuing education program. This paper showed CHP's roles to be reinforced by analyzing his present . task performance and ability in seven task areas as well as the changes of the social environment. In addition, this paper presented retraining areas needed for the reinforcement of the CHP's role in the future, and the development strategy of related continuing education package. The major results are as follows: 1. CHP's main practice area is health care services and management & guidance, whereas the development of health information system is neglected. 2. As a result, CHP plays a role mainly as a health care supplier, a consultant and a health instructor. Therefore CHP's roles to be reinforced are management of the community health system, act as a spokesman and a team member, promotion, assessment, collection & maintenance of information, coordination and research. 3. The areas to be reinforced in CHP's continuing education are (]) aged people's health, (2)?drinking & smoking, (3)?young people's health(including drug and sexualissues), (4) rehabilitation, (5)?administration and management for community health, (6)?partnership & membership, (7) local residents' participation and community development, (8) collection & treatment of health information and (9) environmental issues for community health. 4. The priority in developing continuing education package should be given to the area, which is encountered often in rural area but important, and has a good opportunity to be resolved. The health management of aged people was selected as a top priority by members of the Community Nursing Academic Society. 5. It is recommended that the instruction materials be accommodated to the small scale workshop or seminar in order that CHPs can participate actively in the continuing education program.

The Systems Engineering, as a methodology for engineering and management of today's ever-growing complex system, is a comprehensive and iterative problem-solving process. The process centers on the analysis and management of the stakeholders' needs throughout the entire life-cycle of a system and searches for an optimized system architecture. There are many essential needs and requirements to be met when a system development task is carried out. Systems Engineering Management Plan(SEMP), as a specification for system development process, must be established to satisfy constraints and requirements of stakeholders successfully and to prevent cost overrun and schedule delay. SEMP defines technical management functions and comprehensive plans for managing and controlling the entire system development process, specialty engineering processes, etc. Especially. in the case of a large-scale complex system development program where various disciplinary engineering such as mechanical; electrical; electronics; control; telecommunication; material; civil engineering etc. must be synthesized, it Is essential to develop SEMP to ensure systematic and continuous process improvements for quality and to prevent cost/schedule overruns. This study will enable the process knowledge management on the subject of SEMP as a core systems engineering management effort, that is, definitely defining and continuously managing specification of development process about requirements, functions, and process realization of it using a computer-aided systems engineering software. The paper suggests a systematic SEMP development process and demonstrates a data model and schema for computer-aided systems engineering software, RDD-100, for use in the development and management of SEMP. These are being applied to the systems engineering technology development task for the next-generation high-speed railway systems in progress.

Purpose The research on the effective use of IS needs to embrace the alignment to organization learning process, which expands the limited focus on dynamic capability of IS use. In addition, it should be done in multi-level analysis with system, user, task, and organization. The current study suggests the inclusion of multi-level analysis of effective use of IS in the perspective of exploration and exploitation. Design/methodology/approach This review selected the representative studies in IS discipline which have investigated the effective use of IS, dynamic capability, operational capability, exploration, exploitation, or organizational learning. In the search of academic archives with those keywords, seventeen papers which have been most cited were chosen and validated whether the focus constructs are directly theorized or validated the suggested keywords. In addition, the level of analysis was verified whether it includes one or more levels of system, individual, task, or organization. Based on the initial analysis of dynamic capability, the further review of research on explorational and exploitational capabilities was implemented. Findings The present review study on previous literature on effective use of IS presented that it is largely implemented in the level of individual but few of them has included organization level. Similarly, the direct investigation of explorational and exploitational use of IS has not been done so much. The needs of study on effective use of IS in depth have been inquired for a decade. However, the review presented that it still lacks profound theories and empirical validations compared to those of adoption stage of IS. Based on the review, future research on the transition between explorational and exploitational use of IS is suggested.

IPv6 (IP version 6), which was standardized by the IETF (Internet Engineering Task Force) to cope with existing IPv4 problems, needs several approaches for interoperation with IPv4. The internetworking of IPv6 with IPv4 is an important key to the deployment of the next generation Internet. As the solutions to the transition mechanism, both tunneling and translator methods have been proposed. In this paper, we analyze functional elements for implementation design of a transition mechanism based on the NAT-PT (NAT-Protocol Translation), and propose an extension algorithm that uses ports for effective use of global IPv4 addresses. The algorithm presented in this paper is a method of combining NAT-PT with Port Translation mechanism. The algorithm does not assign an IPv4 address to the host that needs IPv4 address, but allocates a single temporary IPv4 address and a port number in order to identify host.

As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.

A sensor network is a special network that makes physical data sensed by sensor nodes and manages the data. The sensor network is a technology that can apply to many parts of field. It is very important to transmit the data to a user at real-time. The core of the sensor network is a sensor node and small operating system that works in the node. TinyOS developed by UC Berkeley is a sensor network operating system that used many parts of field. It is event-driven and component-based operating system. Basically, it uses non-preemptive scheduler. If an urgent task needs to be executed right away while another task is running, the urgent one must wait until another one is finished. Because of that property, it is hard to guarantee real-time requirement in TinyOS. According to recent study, Priority Level Scheduler, which can let one task preempt another task, was proposed in order to have fast response in TinyOS. It has restrictively 5 priorities, so a higher priority task can preempt a lower priority task. Therefore, this paper suggests Preemptive EDF(Earliest Deadline First) Scheduler that guarantees a real-time requirement and reduces average respond time of user tasks in TinyOS.

In this paper, we deal with robotic automation for assembling car brake modules. A car brake module is comprises of a torque member, two brake pads, and two pad liners. In the assembly process, brake pads and pad liners are needed to be inserted in a torque member. If we use a typical robotic hand for the assembly, task time takes too long. So, we propose two methods. The first method is to use an end effector that has five grippers capable of gripping five assembly parts. In the first method we attached the implemented end effector to a conventional 6 degrees of freedom industrial manipulator and performed the bake module assembly task. Experimental results show that the task time is remarkably reduced. The brake module assembly task needs the robot to change its orientation frequently, so, in the second method, we added one degree of freedom to the end effector that is used in the first method. By attaching it to a conventional 6 degrees of freedom industrial manipulator, we composed a 7 degrees of freedom redundant manipulator. A redundant manipulator has the advantage of flexible manipulation so the robot can change its orientation easily and can perform assembly task very fast. Experimental results show that the second method dramatically reduce whole task time for brake module assembly.

In this paper, we present a new generalized k-Tree-based (CU/PE) allocation model to perform dynamic resource (CU/PE) allocation/deallocation decision for the reconfigurable MSIMD/MIMD multi-dimensional (k-D) mesh-connected architectures. Those reconfigurable multi-SIMD/MIMD systems allow dynamic modes of executing tasks, which are SIMD and MIMD. The MIMD task requires only the free sub-system; however the SIMD task needs not only the free sub-system but also the corresponding free CU. In our new k-Tree-based (CU/PE) allocation model, we introduce two best-fit heuristics for the CU allocation decision: 1) the CU depth first search (CU-DFS) in O(kN$_{f}$ ) time and 2) the CU adjacent search (CU-AS) in O(k2$^{k}$ ) time. By the simulation study, the system performance of these two CU allocation strategies was also investigated. Our simulation results showed that the CU-AS and CU-DFS strategies performed the same system performance when applied for the reconfigurable MSIMD/MIMD 2-D and 3-D mesh-connected architectures.

This study investigates coping strategies of overweight or underweight males in Korea. For this purpose, the authors identify types of stress related to weight management. A qualitative method was utilized to collect the data related to successful weight management experiences of males aged 20-37 years. Data were analyzed based on a motivation theory of coping, which suggests coping strategy elements. The results of this study identified the stress related to weight: dissatisfaction with appearance, others' disapproval of appearance, health problems, weaker athletic ability, negative self-perception, passiveness about appearance, lower romantic attractiveness, others' disapproval of lower romantic attractiveness, weakened task execution capability, and negative stereo-types about task execution capability. In addition, six coping strategies were suggested: improved appearance, improved physical function, improved positive self-perception, more choices to improve appearance, enhanced romantic relationship, and enhanced job performance. This study shows that weight problems in modern society are diverse and complex. Therefore a man who has abnormal weight needs to clarify his stress first and then proposes strategies that are appropriate for each type of stress.
