Domestic exoteric construction market by opening of world construction market with recent FTA of rapidly change. On these time, need quality increase of construction to possess government official and international competitiveness of customer satisfaction by offering consumer building of good quality. Therefore, must establish direction to inspects and must advance forward formation government official's present actual conditions for building company's QI. This study is as following if summarize studying result of formation government official to improve quality in construction spot. First, formation's CEO will for QI need side improvement the formation government official enemy by important thing. Second, at checking activity and systematic action that participate of responsible persons cooperation enterprise space-time by complete charge department organization should be achieved. Third, complete charge department for quality control operation large size construction firm substantially formation Organizational well operate, but heavy hydrogen building company was construed by greatly unprepared misgovernment. AHP analysis result complete charge department is serious necessity, and the CEO under direct control organizational structure was construed by thing which can bring excellent effect in operation management side of quality business side and formation. Therefore, heavy hydrogen building company should does to occupy competitive power high position with tissue at active quality complete charge deputy.

Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

본 연구는 QI부서 근무자들의 의료기관인증제관련 인식이 직무스트레스 및 이직의도에 미치는 영향을 파악하기 위해 시도된 서술적 조사연구이다. 연구기간은 2016년 6월1일부터 2016년 6월15일까지 이루어졌으며, 조사대상자는 의료기관 인증평가에 참여한 경험이 있는 QI부서 근무자 154명이다. 자료분석은 SPSS Win 21.0 프로그램을 이용하였고 영역별 분석은 평균과 표준편차, t-test와 ANOVA, 다중회귀분석으로 하였다. 연구결과에서 의료기관인증제에 대한 QI부서 근무자들의 인식은 5점 만점에 3.35점, 직무스트레스는 3.66점, 이직의도는 3.32점으로 나타났으며, 일반적 특성에 따른 의료기관인증제에 대한 인식도는 성별, 연령, QI부서 근무기간, 직위, 직무 만족도에 따라 유의한 차이가 있었다. 직무스트레스는 직위에서 유의한 차이가 나타났으며, 이직의도는 연령, QI부서 근무기간, 직위, 직무만족도에서 유의한 차이가 있었다. 의료기관인증제에 대한 인식과 직무 스트레스간의 관계는 유의한 양의 상관관계를 보인 반면 이직의도는 유의한 음의 상관관계를 보였다. 따라서 조사대상자의 의료기관인증제 관련 인식이 높을수록 직무스트레스는 높아지고, 이직의도는 감소하였으나 직위와 연령이 낮은 군과 QI부서 근무기간이 10년이상인 군, 직무만족도가 낮은 군일수록 이직의도에서 더 큰 영향을 받는 것으로 나타났다. 그러므로 QI부서 일부 근무자들의 이직의도를 낮추고, 직무 스트레스를 감소시키기 위해서는 업무 부담감을 줄이고 다양한 지원을 위한 노력이 필요할 것으로 사료된다.

Background : To evaluate the frequency and cause of return to the emergency department within 48 hours and to identify the nature of the problem. Methods : We reviewed the medical records of 76 patients who returned to the emregency department within 48 hours from September 1998 to February 1999. Results : Overall revisit rate within 48hours was 2.6%. Of 76 patients, 5(6.6%) had planned return, 64(84.2%) had unplanned return and 7(9.2%) had incomplete documentation. The causes of unplanned return were inadequate medical management (11.8%), discharge against medical advice (27.6%), return after scheduled ambulatory care (22.4%), and unavoidable revisit due to symptom aggrevation or development of new symptom (22.4%). Conclusion : The study provided a basic information for us to improve the quality of emergency care by reducing unnecessary return to the emergency department. It is necessary to monitor continuously the quality of emergency care and to develop the standard of emergency return rate.

Purpose: The objective of this study was to obtain improved susceptibility weighted images (SWI) of the cervical spinal cord using respiratory-induced artifact compensation. Materials and Methods: The artifact from $B_0$ fluctuations by respiration could be compensated using a double navigator echo approach. The two navigators were inserted in an SWI sequence before and after the image readouts. The $B_0$ fluctuation was measured by each navigator echoes, and the inverse of the fluctuation was applied to eliminate the artifact from fluctuation. The degree of compensation was quantified using a quality index (QI) term for compensated imaging using each navigator. Also, the effect of compensation was analyzed according to the position of the spinal cord using QI values. Results: Compensation using navigator echo gave the improved visualization of SWI in cervical spinal cord compared to non-compensated images. Before compensation, images were influenced by artificial noise from motion in both the superior (QI = 0.031) and inferior (QI = 0.043) regions. In most parts of the superior regions, the second navigator resulted in better quality (QI = 0.024, P < 0.01) compared to the first navigator, but in the inferior regions the first navigator showed better quality (QI = 0.033, P < 0.01) after correction. Conclusion: Motion compensation using a double navigator method can increase the improvement of the SWI in the cervical spinal cord. The proposed method makes SWI a useful tool for the diagnosis of spinal cord injury by reducing respiratory-induced artifact.

영상의학과에서 검사한 환자들의 불편사항을 사전설문조사를 통해 개선사항을 조사하고 팀원과 Brain storming을 실시하여 가장 많은 답변인 촬영대기시간단축을 주제로 선정하여 QI활동을 효율적으로 수행할 수 있는 방안을 제시하고자 한다. 2006년 9월부터 2007년 11월까지 세부원인 분류에 따라 각 항목별로 3개월간 QI 실행전과 후의 환자건수를 비교하였다. 환자건수는 환자 한 명 당 촬영한 검사 한 건으로 하였으며 QI실행 후는 QI실행 전 대기건수를 QI팀 회의를 걸쳐 1개월간 개선방안을 모색한 후 개선방안에 따라 시행 하면서 같은 방법으로 1개월간 측정하여 QI활동 전후의 차이를 각각 백분율로 비교하였다. 1. 재촬영원인에 대한 QI활동 전 후 환자촬영 대기건수 비교하였을 때 3.9%의 감소효과 2. 안내부족 원인에 대한 QI활동 전 후 환자촬영 대기건수 비교하였을 때 1.1%의 감소효과 3. 처방착오입력 원인에 대한 QI활동 전 후 환자촬영 대기건수 비교하였을 때 1.1%의 감소효과 4. 응급환자, 통증이 심한 환자, 몸이 불편한 환자 등의 원인에 대한 QI활동 전 후 환자촬영 대기건수 비교하였을 때 12.0%의 감소효과 5. 외래와 병동환자의 촬영중복시간 원인에 대한 QI활동 전 후 환자촬영 대기건수 비교하였을 때 4.7%의 감소효과 환자의 촬영대기건수를 단축하기 위해서는 많은 요인들이 존재한다. 이 요인들을 QI를 통해 영상의학과의 많은 문제점을 찾아내 수정하고 개선하는 것이 QI의 첫걸음이며 영상의학과 QI팀이 결성되어 QI활동을 실행하는 이유라고 할 수 있다.
