In this study, in order to understand contents and ranges of design for the EGR Valve test system for improving quality and performance of EGR Valve, engine performance and exhaust gas characteristic of 3L-class diesel engine was analyzed. Experimental operation of engine performance test was performed with 50% engine load and 20% and 100% opening ratio of EGR Valve. From test of performance and exhaust gas characteristic of engine, torque output of engine and temperature and pressure of inlet and outlet of EGR Valve were measured. As a result, for design of EGR Valve test system, input fluid flow of EGR Valve must be set the same amount with exhaust gas flow that was below of engine speed of 2,500 rpm, and temperature of inlet of EGR Valve must be set under about $510^{\circ}C$. And the difference of temperature between inlet and outlet of EGR Valve must be over than about $200^{\circ}C$. Exhaust gas of inlet and outlet of EGR Valve were under 1 bar that was not considerable, and the difference of pressure between inlet and outlet of EGR Valve were under 1 bar that could not effect on mechanical operation of EGR Valve.

충남의 도청이전이 추진되어 지역의 균형발전을 기본이념으로 하여 지형적으로 충남의 중심부인 홍성과 예산지역에 '내포신도시'가 조성 중에 있다. 2단계의 종료연도인 2015년의 목표달성이 거의 20%의 수준에 머무르고 있다. 그 원인은 매우 복잡하겠지만, 중앙정부의 중앙정부기관이전과 세종특별자치시를 건립하면서 충남이 정책적 지원 대상에서 제외된 것이 가장 큰 원인이 된 셈이다. 이런 문제점을 해소하기 위해서는 중앙정부차원의 혁신도시건설에 준하는 지원이 필요하다. 또한, 자체적으로 국 내외의 지역도시들이 축제를 통하여 지역의 브랜드와 경쟁력을 만드는 것처럼, '내포신도시'만의 정체성과 첨단산업단지를 안고 있는 글로벌 지역의 첨단기술이 아우르는 축제를 핵우산으로 삼아 위기를 기회로 전환하는 전기를 마련하여야 한다. 본 연구는 이런 전략의 뒷받침이 되는 분석과 실질적으로 추진가능한 혁신전략과 축제의 방향성에 대해서 제시하여 '내포신도시'의 현안문제를 해결하는데 도움을 주고자 한다.

Background: Medication errors are common but most often preventable events in any health care setup. Studies on medication errors involving chemotherapeutic drugs are limited. Objective: We studied three aspects of medication errors - prescription, transcription and administration errors in 500 cancer patients who received ambulatory cancer chemotherapy at a resource limited setting government hospital attached cancer centre in South India. The frequency of medication errors, their types and the possible reasons for their occurrence were analysed. Design and Methods: Cross-sectional study using direct observation and chart review in anmbulatory day care unit of a Regional Cancer Centre in South India. Prescription charts of 500 patients during a three month time period were studied and errors analysed. Transcription errors were estimated from the nurses records for these 500 patients who were prescribed anticancer medications or premedication to be administered in the day care centre, direct observations were made during drug administration and administration errors analysed. Medical oncologists prescribing anticancer medications and nurses administering medications also participated. Results: A total of 500 patient observations were made and 41.6% medication errors were detected. Among the total observed errors, 114 (54.8%) were prescription errors, 51(24.5%) were transcribing errors and 43 (20.7%) were administration errors. The majority of the prescription errors were due to missing information (45.5%) and administration errors were mainly due to errors in drug reconstitution (55.8%). There were no life threatening events during the observation period since most of the errors were either intercepted before reaching the patient or were trivial. Conclusions: A high rate of potentially harmful medication errors were intercepted at the ambulatory day care unit of our regional cancer centre. Suggestions have been made to reduce errors in the future by adoption of computerised prescriptions and periodic sensitisation of the responsible health personnel.

이 연구는 2017년부터 고령사회에 진입한 우리나라의 국내 노인복지시설, 특히 경로당이 어떠한 서비스를 제공하고 있는지 알아보고 차후 발전 방향을 제시하였다. 발전 방향 제시를 위해서 독일, 스웨덴, 일본, 3곳의 사례를 조사하였고 12명의 고령층을 대상으로 심층인터뷰를 진행하였다. 심층인터뷰와 사례조사에 따르면 첫째, 많은 프로그램으로 사람들이 많이 참여할 수 있도록 하는 것, 둘째, 경로당이 결코 나이가 많은 노인들만 이용하는 곳이 아니라는 분위기로 만들어야 한다는 것, 셋째, 노인들이 스스로 사회에 참여하고 자립할 수 있도록 프로그램을 제공하는 것이 중요하다. 현재 경로당은 지역별로 다른 프로그램을 적용하고 있어 어떤 방식으로 프로그램이 진행되는지 알지 못했다는 점이 이 연구의 한계점이다. 향후 연구에서는 국내의 경로당 사례를 조사하여 국내의 특성에 맞고 지역 차이 없이 공통으로 진행될 수 있는 프로그램의 구체적인 제안이 필요하다.

Purpose - In general, large companies have larger organizations, funds, and systems to provide more effective and efficient services in the market. However, development needs to support the livelihood of ordinary citizens who work for small businesses as well. This research suggests that a new distribution channel, called a "foothold style Kosa mart," that cooperates jointly with a distribution center and a large discount mart can provide direct solutions to small and mid-size distributors. This new distribution channel can achieve a limited type of "Nadle shop (small supermarket) foster project" related to building a joint distribution center and improvement in wholesale supply. Research design, data, and methodology - Data about the Korea distribution situation, the Nadle stores, and the logistics centers were collected from literature, Statistics Korea, journals, and reports. Specifically, we investigated information about Kosa Mart and Nadle stores. We focused on the redesign of the distribution center for the Nadle store. Results - The Kosa Mart distribution center now includes 18 warehouses, and has been handling 2000-3000 items. Most of the warehouses have been simply designed and items loaded and stored without refrigeration; thus, it is possible to store only products of certain manufactured goods. The current logistics center has no wholesale function because it failed to resolve the joint purchasing and product supply issues of competitively priced products. Conclusions - This study aimed to identify ways to strengthen the competitiveness of small- and medium-sized retailers. A Kosa Mart redesign aims to unifying the logistics center, stores, and customers. First, the joint wholesale logistics system, equipped with an integrated ordering system, needs to process customer orders and store orders at the same time. Second, excellent small business product development has to connect with production. Third, the store composition needs to support a shipping hub. Fourth, the Mart differentiates itself from convenience store goods by supplying regional and specialized products to customers. Fifth, a service buying agent and direct transactions between producers and consumers need to be established, and exhibits and displays of goods need to be improved.
