We develop some evaluation tool and indicators for the scores for medical equipment replacement in hospital. There has been no research for Korean hospitals although there are many for foreign medical institutions. In this paper, among many variables that were obtained from the previous studies, eleven variables are selected as indicators and tied as three groups. And then we obtain scores of medical equipments based on the weighted values of those indicators. We can make decisions whether we replace medical equipments or not by ranking the medical equipments based on the scores. This paper shows that we can make decisions to replace medical equipments very objectively and effectively using the evaluation tool and indicators we develop.

In Canada Deuterium Uranium (CANDU)-type nuclear power plants, the reactor is composed of 380 fuel channels and refueling is performed on one or two channels per day. At the time of refueling, the fluid force of the cooling water inside the channel is exploited. New fuel added upstream of the fuel channel is moved downstream by the fluid force of the cooling water, and the used fuel is pushed out. Through this process, refueling is completed. Among the 380 fuel channels, outer rows 1 and 2 (called the FARE channel) make the process of using only the internal fluid force impossible because of the low flow rate of the channel cooling water. Therefore, a Flow Assist Ram Extension (FARE) tool, a refueling aid, is used to refuel these channels in order to compensate for the insufficient fluid force. The FARE tool causes flow resistance, thus allowing the fuel to be moved down with the flow of cooling water. Although the existing FARE tool can perform refueling in Korean plants, the coolant flow rate is reduced to below 80% of the normal flow for some time during refueling. A Flow rate below 80% of the normal flow cause low flow rate alarm signal in the plant operation. A flow rate below 80% of the normal flow may cause difficulties in the plant operation because of the increase in the coolant temperature of the channel. A new and improved FARE tool is needed to address the limitations of the existing FARE tool. In this study, we identified the cause of the low flow phenomena of the existing FARE tool. A new and improved FARE tool has been designed and manufactured. The improved FARE tool has been tested many times using laboratory test apparatus and was redesigned until satisfactory results were obtained. In order to confirm the performance of the improved FARE tool in a real plant, the final design FARE tool was tested at Wolsong Nuclear Power Plant Unit 2. The test was carried out successfully and the low flow rate alarm signal was eliminated during refueling. Several additional improved FARE tools have been manufactured. These improved FARE tools are currently being used for Korean CANDU plant refueling.

1990년대 이후로 객체 지향과 관련된 기술이 학계 및 산업계 전반에 정착됨으로써 소프트웨어의 생산성과 재사용성 향상에 큰 도움이 되고 있다. 다양한 관점에서 연구되고 있는 객체 지향 기술 중에서 객체 지향 기술의 구체적인 응용 분야로 언급될 수 있는 한가지 분야가 CASE 도구에 관련된 것이며 또 다른 하나가 컴포넌트 기술에 관한 것이다. 본 논문에서는 이러한 컴포넌트 기술을 CASE 도구에 적용한 예를 다룬다. 본 논문에서는 기존에 개발되었던 객체 지향 CASE 도구인 OODesigner에 COM/OLE 기반의 복합 문서 지원 기술을 지원하도록 추가로 개발한 연구 결과를 제시한다. 본 연구의 결과로 구현된 OLE 컨테이너 기능을 갖는 OODesigner는 윈도우 시스템에서 OLE 서버로 작동될 수 있는 응용 프로그램들과 상호 협동 작용을 하며 수행될 수 있기 때문에 기존의 CASE 도구가 지원하지 못하는 유용한 문서화 기능을 제공할 수 있다. 즉 객체 지향 관련 설계 문서의 내용을 OODesigner로 편집함과 동시에 OLE 서버 기능을 지원하는 녹음기, 엑셀과 같은 소프트웨어들을 연결하여 수행함으로써 일관성 있고 막강한 문서화 작업을 수행할 수 있다.

본 논문은 선원 훈련을 보다 효율적으로 수행하기 위한 가상현실 기반 선원 훈련 플랫폼을 위한 저작도구를 제안한다. 제안하는 저작도구는 훈련의 효율도를 높이기 위해 실 선박 환경을 3D 스캔하여 가상현실 환경으로 불러오는 가상환경 구축부와 다양한 시나리오 기반의 훈련 내용을 소화할 수 있는 드래그-앤-드롭 기반의 스크립트 편집부를 지원한다. 본 저작 도구에서는 가상현실 장비들을 지원하고 실환경을 3D 스캔을 통해 가상 현실로 변환하기 때문에 피훈련자는 훈련이 필요한 실환경 내에서 요구되는 동일한 훈련을 이행하게 됨으로써 피훈련자의 몰입감과 훈련 효과를 높인다. 또한 다양한 선박 환경에 대한 훈련 시뮬레이션을 빠른 시간 내에 제작할 수 있게 함으로써 제작에 필요한 비용을 줄인다. 본 저작도구는 시나리오 편집부를 통해 다중 참여형 훈련 시나리오의 편집과 임무 평가를 가능하게 한다.

Purpose: This study was conducted to develop standards to ensure nursing process-based care of oxygen therapy and airway suctioning and to develop a performance measurement tool to evaluate the care applied according to the standards, and finally to determine validity of the standards and the tool. Methods: The standards and the tool were reviewed by a panel of experts and refined based on the panel's suggestions. Validity of the standards and the tool were examined through surveying a total of 366 hospital nurses. Results: The mean validity scores of the performance measurement standards and the tool were 3.58 and 3.55, respectively, out of 4.00. So the performance measurement standards and the tool in this study were found to be acceptable in evaluating quality of nursing care provided at patient admission and discharge. Conclusion: This result indicates that the performance measurement standards and the tool developed in this study are valid instruments to monitor and improve quality of nursing care for oxygen therapy and airway suctioning.

고속 가공과 저중량 설계에 대한 수요가 증가함에 따라, 공작기계 주축의 진동 발생 가능성이 증가하고 있다. 또한 초정밀 가공에서 주축의 진동은 공작물 표면 형상에 큰 영향을 끼치게 된다. 다양한 가공 공정의 가공 정밀도를 향상시키기 위해, 공작기계 주축 진동 문제를 해결하여야 한다. 이 논문에서, 공작기계 주축의 진동 억제를 위해 TiC-SKH51 금속 기지 복합재가 사용되었다. TiC-SKH51 복합재의 동적 특성을 확인하기 위해 충격 망치 시험을 수행하였다. FEA의 모드 분석 결과와 충격 망치 시험 결과를 비교하여 FEA의 신뢰성을 확인한 후, 공작기계 주축 모델의 해석이 실행되었다. FEA 결과로부터 진동 발생 억제를 위해 TiC-SKH51 복합재를 적용한 공작기계 주축이 사용될 수 있음을 확인하였다.

Purpose: The purposes of this study were to develop the constipation assessment tool for identifying their bowel movement patterns, and to provide basic information for the assessment and intervention protocol on constipation for patients with terminal cancers. Methods: The study followed the steps: the first step was to build a conceptual framework based on literature review; the second step was to develop a tentative instrument by analyzing the conceptual framework and existing instruments; the third step was to test content validity and reliability; and the final step was to apply the tool to patients with terminal cancers (N=112). Results: The constipation assessment tool was consisted of total nine items; under the categories of subjective and objective data for diagnosis had 4 items, and under the initial assessment category which includes stool type, physical examination, and abdomen X-ray had 5 items. Conclusion: The constipation assessment tool developed in this study is very easy to use and useful in nursing practice, especially in hospice and palliative care setting. Particularly this tool has items on patient assessment which would be considered as an evidence for choosing nursing interventions. Based on the constipation assessment tool, the development and application of intervention protocol on constipation for patients with terminal cancers is warranted in future research.
