Objective : Even in the patients with neurologically good outcome after intracranial aneurysm surgery, their perception of health is an important outcome issue. This study aimed to investigate the quality of life (QOL) and its predictors of patients who had a good outcome following anterior circulation aneurysm surgery as using the World Health Organization Quality of Life instrument-Korean version. Methods : We treated 280 patients with 290 intracranial aneurysms for 2 years. This questionnaire was taken and validated by 99 patients whose Glasgow Outcome Scale score was 4 and more and Global deterioration scale 3 and less at 6 months after the operation, and 85 normal persons. Each domain and facet was compared between the two groups, and a subgroup analysis was performed on the QOL values and hospital expenses of the aneurysm patients according to the type of craniotomy, approach, bleeding of the aneurysm and brain injury. Results : Aneurysm patients showed a lower quality of life compared with control patients in level of independence, psychological, environmental, and spiritual domains. In the environmental domain, there were significant intergroup differences according to the type of craniotomy and the surgical approach used on the patients (p<0.05). The hospital charges were also significantly different according to the type of craniotomy (p<0.05). Conclusion : Despite good neurological status, patients surgically treated for anterior circulation aneurysm have a low quality of life. The craniotomy size may affect the QOL of patients who underwent an anterior circulation aneurysm surgery and exhibited a good outcome.

Weld bead quality in tailored blank(TB) is critically affected by edge preparation of sheets. The edge quality of prepared sheets for TB can be classified into straightness and the cross section quality of sheared plane such as a ratio of shear face, shear plane angle, etc. In order to have a good edg quality for butt-welding sheets, precision shearing will be recommended. In this paper, the feasibility of a conventional mechanical shearing as the edge preparation for tailored blanks is studyied. It reveals that fine shearing may not be the unique solution as it is generally accepted. To obtain the good shearing condition with a conventional mechanical shearing, experiments were carried out using Tahuchi method. The major parameters affecting a sheared contour are the clearance between upper blade and lower blade, and shear angle. The optimal shearing condition yields a very good straightness along the entire length of the cut, which gives a butt joint gap less than 10% of the base material thickness. The good cross section of sheared plane is also achieved in the optimal shearing condition such as a ratio of the shear face above 65%, a cross section's shear plane angle above 85%, little burr, which is providing finally good weld beads.

Medical school students learn a lot about medical knowledge and clinical experience in the classroom. Teaching is a main focus in medical schools; therefore, it is necessary to identify the characteristics of good teaching. The aim of this study is to analyze the characteristics of high-quality education in medical schools. In this study, in-depth interviews were conducted over two weeks on twelve fourth-year medical students. Participants were asked to define high-quality education, list the general ways in which high-quality classes are delivered, mention cases where they have experienced high-quality teaching, and describe the attitude required of students to make high-quality education possible. The results showed that students want to be taught in an interactive way on the core content needed in an actual clinical setting for the goal of cultivating primary care physicians. They want their education to include not only medical knowledge, but also liberal art subjects such as politics, economics, sociology, culture and ethics education to help instill a sound value system. In particular, students stressed the importance of instructors delivering appropriate post-evaluation feedback, and they also emphasized that learner mindset and attitude is important in supporting high-quality teaching in class. This paper also summarizes the elements of high-quality teaching in terms of educational goals, content, and method, and examines cases of instructors who have delivered high-quality classes.

In this paper, we analyze quality loss function(QLF) of Taguchi. Taguchi method of QLF gives more advanced measure process capability than classic capacity(i.e. Cp). We first discuss of QLF and Cp and give one good example of QLF. Because of simplicity of QLF, it is not good fit to a, pp.y in the real field. We suggest interval quantity-loss cost function and total loss cost(TLC) which modify QLF. Also we give one example which can be obtained in the real field.

To implement total quality management(TQM), firms and institutions have strategically used quality awards models. In this paper we analyzed the national quality awards of G-20 members such as United States, Europe, Japan, Canada, Australia and Korea. There are three main points to analysis; First, "which type of model is good for Korea?", even though Korea already has adopted MBNQA model. Second, "Are the core values really different from each models?". And third, "Is there any difference in the criteria structure and value points system?" This study aims to design a National Quality Award which is good for the Korean companies and organizations. After analyzing the current quality awards models, we propose some suggestion about core value setting Korean-specific criteria development and value points system change.

Background: Shift work and/or sleep quality may affect health. We investigated whether shift work and sleep quality, separately and jointly, were associated with abnormal levels of triglycerides, total cholesterol (TC), and low-and high-density lipoprotein cholesterol in 360 police officers (27.5% women). Methods: Triglycerides, TC, and high-density lipoprotein were analyzed on the Abbott Architect; low-density lipoprotein was calculated. Shift work was assessed using City of Buffalo payroll work history records. Sleep quality (good, ${\leq}5$; intermediate, 6-8; poor, ${\geq}9$) was assessed using the Pittsburgh Sleep Quality Index questionnaire. A shift work + sleep quality variable was created: day plus good sleep; day plus poor sleep; afternoon/night plus good; and poor sleep quality. Mean values of lipid biomarkers were compared across categories of the exposures using analysis of variance/analysis of covariance. Results: Shift work was not significantly associated with lipids. However, as sleep quality worsened, mean levels of triglycerides and TC gradually increased but only among female officers (age- and race-adjusted p = 0.013 and 0.030, respectively). Age significantly modified the association between sleep quality and TC. Among officers ${\geq}40$ years old, those reporting poor sleep quality had a significantly higher mean level of TC ($202.9{\pm}3.7mg/dL$) compared with those reporting good sleep quality ($190.6{\pm}4.0mg/dL$) (gender- and race-adjusted p = 0.010). Female officers who worked the day shift and also reported good sleep quality had the lowest mean level of TC compared with women in the other three categories (p = 0.014). Conclusion: Sleep quality and its combined influence with shift work may play a role in the alteration of some lipid measures.

이 논문은 장기요양서비스의 질 향상을 위하여 서비스 목표라 할 수 있는 '좋은 돌봄'의 개념을 정립하고 그 구성요소를 찾아내며, 좋은 돌봄을 산출할 수 있는 조건에 대해 탐색했다. 또한 서비스 질을 어떻게 측정하는 것이 바람직한가에 대해서도 모색하였다. 이를 위하여 정부가 채택하고 있는 질 확보전략을 비판적으로 평가하고, 돌봄의 근원적 속성을 탐구한 선행 문헌들을 검토하고 지난 5년간 서비스 제공 경험에서 축적된 서비스 현장의 지혜를 질적연구방법을 통해 담아내고자 하였다. 연구 결과, '좋은 돌봄'은 개개인의 총체적 삶의 질(total quality life)이 가능한 최대로 보장될 수 있도록 단순히 신체적 기능적 욕구 충족만이 아니라 진정한 관심이 결합되어야 한다. 좋은 돌봄을 위한 가장 중요한 조건은 '좋은 돌봄관계'를 형성하는 것이다. 돌봄제공자와 돌봄수급자 간 관계가 시장규범에 훼손되지 않고, 상호신뢰 및 존중과 진정한 소통으로 돌봄수급자 욕구를 중심에 둔 개별화된 서비스를 제공하여야 한다. 평가체계는 전면적인 상대평가보다는 시설서비스의 핵심적 질에 대하여는 기관규모별 절대기준 인증체계를 마련하고, 인증기준 이상 부분은 기관마다 자율적으로 특성화하는 것이 바람직하다. 방문 재가서비스 평가는 이용자 만족도, 돌봄종사자 만족도, 재가서비스기관의 사례관리체계 등이 평가내용으로 구성되는 것이 적절하다.
