Recently the number of rural development plans are increased and projects supported by government are various. These makes rural plans important. But there are many gaps between proposed plan and implementation. These gaps were wasteful in terms of resource management. This study examines differences between plan and implementation and the reasons why they are occurred. For this purpose, we did a case study which is focused on the four-year implementation of 2004-2006 "Unique Experience Village Master Plan" of Seochon, Chungbuk. As a result, we verified facts of gaps and causes, and two major causes were detected : one is the absence of operating and managing body(such as promoter of project, village leader, residences), and the other is inadequate master plan.

In this manuscript, a modified single sampling plan is proposed for the inspection of products in which the nonconforming items can be classified in to two categories namely critical and non-critical; and explained with the help of industrial example. The operating procedure of this plan is also proposed and the performance measures such as the probability of acceptance, average sample number, average total inspection and average out going quality are also derived. The optimal parameters are determined which will have minimum sample size. The efficiency of the proposed plan is also discussed over the conventional single sampling plan. The extensive tables for selecting a modified single sampling plan based on AQL and LQL are provided for both Binomial and Poisson distributions and explained with the help of industrial data.

Traditional acceptance sampling plans have focused on the proportion of nonconforming items as an attribute criterion for quality. In today's modern quality management under high quality production environments, the reduction of the deviation from a target value in a quality characteristic has become the most important purpose. In consequence, various inspection plans for the purpose of reducing the deviation from the target value in the quality characteristic have been investigated. In this case, a concept of the quality loss evaluated by the deviation from the target value has been accepted as the variable evaluation criterion of quality. Further, some quality measures based on the quality loss have been devised; e.g. the process loss and the process capability index. Then, as one of inspection plans based on the quality loss, the rigorous design procedure for the variable sampling plan having desired operating characteristics (VS-OC plan) indexed by the quality loss has been proposed by Yen and Chang in 2009. By the way, since the estimator of the quality loss obeys the non-central chi-square distribution, the rigorous design procedure for the VS-OC plan indexed by the quality loss is complicated. In particular, the rigorous design procedure for the VS-OC plan requires a large number of the repetitive and complicated numerical calculation about the non-central chi-square distribution. On the other hand, an approximate design procedure for the VS-OC plan has been proposed before the proposal of the above rigorous design procedure. The approximate design procedure for the VS-OC plan has been constructed by combining Patnaik approximation relating the non-central chi-square distribution to the central chi-square distribution and Wilson-Hilferty approximation relating the central chi-square distribution to the standard normal distribution. Then, the approximate design procedure has been devised as a convenient procedure without complicated and repetitive numerical calculations. In this study, through some comparisons between the rigorous and approximate design procedures, the applicability of the approximate design procedure has been confirmed.

Purpose: Recently, the operating unit remodeling compititon has been increasing rapidly in Korea, but there are no design infomation for spatial planning of sterile supply storage. Therefore, the propose of this study is to present area composition of the operating unit after remodeling. Methods: For literature review, the 6 studies and guidelines of operating unit(guidelines in the U.S, Australia, UK and Korea and 2 studies in Korea) conducted surveys and analysis. Room and space composition and zone of operating unit are redefined for this study. For obtaining area, to conduct masuring and calcuating of document of operating unit before and after remodeling in 3 cases. There are some patterns of plan in operaing unit by sterile supply storage. This study derived data for attributes of area composition of sterile supply storage. Results: The results of this study are as follows: First, Reviewing previous studies and Guidelines, for this study the suggested model was 5 zones(Operating zone, Support zone, Patient zone, Staff zone, Circulation zone) and redefined each room and space. Second, For infection control, sterile supply storage was provided to directly accessible to the operating room. Third, According to ralation of operting room and sterile supply storage, there are two types : 'double loaded type' and 'single loded type'. Sterile supply storage shall increase area of ciculation zone. Implications: This study can be used as primary data on remodeling of operating unit. In addition, it suggests that for infect control sterile supply storage is functional area.

Four dimensional(4-D) trajectory modeling is conducted based on flight plan. The flight plan is divided into several segments which represent certain operating flight modes. Thrust, drag and fuel consumption rate of an aircraft are calculated using BADA provided by Eurocontrol. The trajectory is modeled with the rate of climb/descent calculated with Total-Energy Equation. The simulation results with a typical aircraft and its flight plan indicate that the trajectory modeled corresponds well with the suggested flight plan. The performance profiles including total endurance time and time history for speed, thrust, drag and fuel consumption were also appropriately generated.

It is inadequate to compare operating costs between some logging machines with a low rate of utilization of them except the effect of operating time. The operating volume to maximize the utilization of the logging machines is different from each other, thus it is important to choose the proper logging machines and operating system according to the size of logging management. This study presents one of the methods to choose the economical optimum logging machines according to the operating volume to promote the economical efficiency of the machines. In order to go ahead with the Korean forestry mechanization plan, it should be considered which machine or operating system has the economical priority and if it can be suitable to the effect of wage increment.

In the 4th Industrial Revolution, the competitiveness of the software industry is important, and as a solution to fundamentally secure the competitiveness of the software industry, education classes should be provided to educate high quality software personnel in educational institutions. Despite this social situation, software-related classes in universities are largely composed of competitive or individual learning structures. Cooperative learning is a learning model that can complement the problems of competitive and individual learning. Cooperative learning is more effective in improving academic achievement than individual or competitive learning. In addition, most learners have the advantage of having a more desirable self-image by having a successful experience. In this paper, we apply a pair check model, which is a type of cooperative learning, in operating system classes. In addition, the class procedure and instruction plan are designed to apply the pair check model. We analyze the test results to analyze the performance of the cooperative learning model.

Purpose: This study was done to evaluate the operating status of community-based home health center for revitalization of the centers. Method: In this study performance data including organization plan and service utilization plan were evaluated according process theory. Target of evaluation was the community-based home health care center. Results: The vulnerable part of the organization was the information system and financial resources. The home health center introduced PDA (Personal Digital Assistants) in 2005, however home health care nurses did not make full use of it. This service received full support from Seoul city and local government and there were no other sources of income. The vulnerable part of service utilization was service expansion and standardization due to vulnerability of organizational aspects. Conclusions: The home health care center provides high quality services to underprivileged people. In the future, these services should be provided with equity for continuous health care for this population.

This paper focuses on production planning and scheduling problems in an assembly system operating on a make-to-order basis. Due dates are considered as constraints in the problems, that is, tardiness is not allowed. Since the planning problem is a higher-level decision making than the scheduling problem, the scheduling problem is solved using a production plan obtained by solving the planning problem. We suggest heuristic procedures in which aggregated information is used when the production planning problem is solved while more detailed information is used when the scheduling problem is solved. Since a feasible schedule may not be obtained from a production plan, an iterative approach is employed in the two procedures to obtain a solution that is feasible for both the production planning and scheduling problems. Computational tests on randomly generated test problems are done to show the performance of these algorithms, and results are reported.
