The Korean medical device industry has increased dramatically due to various investments in the domestic medical device industry and the introduction of new technologies, but the domestic medical device usage rate in great hospital is still low. In this paper, improvement point for domestic medical device was suggested by domestic medical device usage rate and user and manager's perception survey in great hospitals in Korea. To do this, a survey on the types of medical devices and domestic medical device usage rates were conducted at four national university hospitals in Korea. From this results, the priority survey medical devices were selected. Improvements of Korean medical devices were suggested by failure mode analysis and user awareness surveys for the priority survey medical devices.

Objectives As awareness of the public about Korean medicine health care and the social demand about improvement for quality of health care service is constantly rising, the quality evaluation of Korean medicine health care service is needed to improve the quality. Through trial of Delphi method, we tried to set the priority in short, medium, long term among the disease which is the subject of quality assessment. Methods Carrying out the delphi survey to 50 experts of korean medicine who were recommended by the 41 member societies of Korean medicine and related organizations, we selected final candidates for quality assessment. It is composed with total 2 rounds, and we investigated the priority in three aspects; the importance of the matter, possibility quality assessment, potential about if there's any chance of improvement. Results By delphi method, we set the priority of quality assessment. Base on the result of the second round, we classified importance of the questions into above average, average, below average, and categorized items as short, medium, long term according on the final priority. We classified of musculoskeletal diseases and diseases of connective tissues and musculoskeletal injury as short term and cerebrovascular disease and disease of nerve system and malignant neoplasm as medium term, disease of digestive organs and diseases, symptoms and abnormal findings in clinical field or inspections which are not categorized as long term. Conclusions We set the subjects of quality assessment by delphi survey by experts, and classified into short, medium, long term. Further research is necessary for execution the Quality Assessment to each of the candidate. Also, we can send feedback to medical institution base on the result of Quality Assessment. then it would be able to induce the improvement in quality of medical institution by itself.

It is very important to evaluate the priority of prevention factors and strategies in order to minimize industrial accident. It provides decisive information for accident prevention and safety management. Therefore, this paper proposes evaluation method of the priority through statistic testing with prevention factors and strategies by the cause analysis of cause and effect models. Especially, this paper uses priority matrix criterion to justify application of rank and objectivity. This paper is based on the results of a questionnaire of workers and managers who are engaged by real manufacturing and construction industries with less than 300 workers in the central region of Korea, where most of the fatal accidents have happened. Finally, the result provides one way to implement safety management for industrial accident prevention.

Background: Breast cancer is the most common malignancy among women in both developed and developing countries. The burden is increasing in low-income and middle-income countries (LMCs) and threatens the public health of such societies. Introduction of expensive monoclonal antibodies to cancer treatment regimens poses a real challenge in the health systems of LMCs. Despite controversy of cost-effectiveness of bevacizumab in breast cancer, some studies indicate gain of patients from this drug. The present study aimed to propose a priority setting model for administration of anti-angiogenic agents in breast cancer via assessment of tumor angiogenesis by the microvessel density (MVD) method and associations with clinicopathological characteristics (including simultaneous mutations of TP53 and HER-2 genes). Materials and Methods: Age, axillary lymph nodes status, tumor size, stage and grade, estrogen and progesterone receptors status, HER-2/neu status (by immunohistochemistry and FISH test), TP53 mutation, Ki-67 (for proliferation assay) and CD34 (for angiogenesis assay) were assessed in 111 breast cancer patients. The molecular subtype of each tumor was also determined and correlations of simultaneous mutations of HER-2 and p53 genes with angiogenesis and other clinicopathological characteristics were evaluated. Results: There were significant associations between simultaneous mutations of HER-2 and p53 genes and all other parameters except tumor size. The degree of angiogenesis in the ERBB2 subtype was greater than the others. Younger patients showed a higher angiogenesis rate rather those older than 50 years. Conclusions: Our results demonstrated that patients with simultaneous mutations of HER-2 and p53 genes, those with ERBB2 molecular subtype and also younger women (often triple negative) seem more eligible for obtaining anti-angiogenic agents. These results suggest a model for priority setting of patients with breast cancer for treatment with anti-angiogenic drugs in LMCs.

This study was performed in order to contributing the conflict factors which largely affects the efficient promotion of Urban Rehabilitation Project. then, it aims to induce conflict factors which affect the business period and business expense through PLS Regression Analysis. The data was build up from union members, tenants and merchants who are living in the completed urban rehabilitation area. In the case of 'Business period', it shows the priority on conflict factors in this order such as the 'Approval and Authorization for union establishment', 'Approval and Plan for business enforcement' and 'Interruption of interest group related to service business such as business delay'. In addition, In the case of 'Business expenses', it shows the priority on conflict factors in this order such as the 'Approval and Authorization for union establishment', 'Selling contract', 'Report of Demolition and Loss' and 'Plan and Authorization of Management disposition'.

Criteria for rehabilitation priority are discussed to evaluate structural stability of deteriorated water transport and transmission pipes, in this study. For the purposes, safety factor is introduced and estimated by measuring tensile strength and by analyzing stress caused by the internal-external loads working on buried pipe body. Related informations are surveyed and collected under various conditions in the fields by digging out and the structural stability is assessed. In the evaluation results of structural safety, it is shown that steel pipe is more affected by external load than internal load. The average external load is estimated as $53.7kg/cm^2$ and total hoop stress is estimated by $2676.5kg/cm^2$. Also, Poisson effect into longitudinal direction due to internal and external loads is most influential on hoop stress. The calculated safety factors of hoop stress are ranged from 0.7 to 5.2 with average value of 2.1, considering a bending stress to longitudinal direction. The decision of rehabilitation priority by safety factors show that structural safety of CIP sample 1(S1) was assessed at the lowest order with safety factor value, 0.7 and that of DI sample 15(S15) was evaluated as the most stable in structural aspect.

Well planned rehabilitation order of pipes is essential for efficient maintenance and management of Water Distribution Systems. In this study, not only deterioration rate of pipes but also structural and nonstructural failure which causes abnormal condition of WDS is considered to determine rehabilitation order. Probabilistic Neural Network is used for calculating deterioration rate at present and the importance of pipes is computed under structural and nonstructural failure by using Pipe by Pipe Failure Analysis and Effect Index. Utopian Approach, one of the Multi-Criteria Decision Making methods, is used for assessment of final rehabilitation order based on distance measure between utopian point and alternative one. Developed model in this study shows that it gives more reliable results than existing methods considering hydraulic relative importance does in application to real networks. In this point, the newly developed model, which gives advantages over existing models, can make a credible decision and simple application.

Our government is interested in the rehabilitation for the old sewer rather than the construction of a new sewer system. However, the research work on the sewer rehabilitation is not sufficient as much as the interest on the rehabilitation is increased. There are some research works for the determination of rehabilitation time by the genetic algorithm in Korea and foreign countries. However, the previous studies have considered the simple elements for the determination of the rehabilitation time and so the complex decision-making according to the degree of sewer superannuation has not been performed. Therefore, in this study, we estimate the capacity and Ⅰ/Ⅰ of sewer and determine the priority of the optimal rehabilitation for each outfall within the draining system. Also we develop the optimal rehabilitation decision making system for the cost estimation of optimal rehabilitation using the genetic algorithm.

A CCTV inspection method has been widely used to assess sewer condition and performance, but Korea lacks a proper decision support system for prioritizing sewer repair and rehabilitation (R&R). The objective of this paper is to introduce the results that we have developed in the Sewer Condition Assessment and Rehabilitation Decision-making (SCARD) Program using MS-EXCEL. The SCARD-Program is based on a standardized defect score for sewer structural and hydraulic assessment. Priorities are ranked based on risk scores, which are calculated by multiplying the sewer severity scores by the environmental impacts. This program is composed of three parts, which are decision-making for sewer condition and performance assessment, decision-making for sewer R&R priority assessment, and decision-making for optimal budget allocation. The SCARD-Program is useful for decision-makers, as it enables them to assess the sewer condition and to prioritize sewer R&R within the limited annual budget. In the future, this program logic will applied to the GIS-based sewer asset management system in local governments.

The purpose of this study was to provide an operational model of the rehabilitation room for fire officers at disaster sites to improve the safety and resilience of fire officers. Therefore, we analyzed the operation related elements of the rehabilitation room-such as overseas rehabilitation room operation cases and previous studies- and managed different factors including, but not limited to, management and human resources, equipment and facility, and accessibility and convenience factors; afterward, the relative importance and importance of sub-layers in each field were measured. The priority of items for the operation of the rehabilitation room for fire officers at disaster sites was elucidated; after expert analysis, it was found that human resources were the most crucial factor. Finally, it was found that, in descending order, accessibility and convenience, administrative, equipment, and facility factors were also essential. Based on this, we proposed a rehabilitation room operation guideline for disaster sites.
