In addition to protocol adjustments during CT examinations, the height of the CT table can also affect image quality. Therefore, this study aimed to investigate the change in image quality depending on the height of the table in brain CT, which accounts for a large proportion of CT examinations, by measuring signal to contrast to noise ratio (CNR) and noise power spectrum (NPS) using the head phantom and evaluating them. The head phantom images were acquired using Philips Brilliance iCT 256. When the image was acquired, the table height was adjusted to 815, 865, 915, 965, 1015, and 1030 mm, respectively, and each scan was performed 3 times for each height. The CNR result showed the highest value at 965 mm, which is the height adjacent to the center of the head phantom. NPS showed the lowest NPS at 915 mm, the center of the head phantom in the low frequency region. From these results, it can be seen that the height of the table in CT examination is closely related to the image quality, and it can be seen the characteristics of image quality according to CT table through quantitative evaluation methods such as CNR and NPS.

Purpose: This study was conducted to exam the effect of a biomedical ethics education program on the consciousness of biomedical ethics, moral sensitivity and critical thinking disposition in nursing students. Method: A quasi-experimental research design and repeated measured ANOVA were used. The participants were divided into an experimental group (n=148) and a control group (n=169). Each group underwent freshman university nursing training in two major cities. The mean age was 21.3 years and the time of providing the biomedical ethics education program was 15 hours for 15 weeks. The experimental group was provided biomedical ethics education during the semester; the control group was not provided any biomedical ethics education. Results: The consciousness of biomedical ethics was increased significantly in the experimental group (t=-4.724, p<.001). Moral sensitivity was increased significantly in the experimental group (t=-2.021, p<.004). Critical thinking disposition was increased significantly in the experimental group (t=-5.775, p<.001). Conclusion: The results of the study show that providing biomedical ethics education to nursing students is an effective method to increase the consciousness of biomedical ethics, moral sensitivity and critical thinking disposition.

Recently, inn the ubiquitous home where a variety of home devices and sensors are inter-connected, various services can be provided through wired and wireless networks invisibly. The convenience of users can be maximized by using intelligent and adaptive interoperability technologies in the home. In this paper, it is designed u-apartment that connected parking system of intelligental form and medical service system based on USN environment with existing apartment. Intelligental form parking system is designed specific structure architecture for effective improvement of parking space and medical service system propose a design about health management of future. In this paper, we propose integrated u-apartment design with parking system and medical equipment using RFID system in ubiquitous environment.

The pixels used in a digital X-ray detector have different sensitivities and offset values. A non-uniform image is consequently obtained. Flat-field correction was introduced to resolve this problem and carried out image preprocessing in a digital imaging system. Nevertheless, the non-uniform images caused by several reasons have been being occasionally acquired. In this study, the non-uniform images acquired in digital imaging systems were applied to flat-field correction, and NPSs were calculated and analyzed with those images before and after correction. It was confirmed that low frequency noise were effectively eliminated.

Purpose : The main objective of this paper is, to assess a body of research evidence that articulates the impact of environment-related factors on wayfinding for people with dementia who reside in Long-term care Facilities. The study also aims at identifying design implications that can be incorporated into design process and design decisions to improve wayfinding abilities for people with dementia. Methods : Comprehensive literature review has been conducted to identify empirical studies and carefully investigated peer-reviewed articles published in many different fields including architecture, psychology, nursing to gerontology. Results : The review found a growing body of studies that identified environment-related factors that improve wayfinding of people with Dementia living in long-term care facilities. Implications : The findings of the review can be considered as design guidelines to support the wayfinding abilities of people with dementia living in long-term care Facilities.

Purpose: This paper's main objective is to provide a systematic review of research evidence that articulates the impact of environment-related factors on wandering for people with dementia in the Long-term Care Facilities. Another objective of this study is to identify design implications that can be incorporated into design process and decisions to positively improve wandering abilities for people with dementia. Methods: Comprehensive literature review has been performed to investigate empirical studies and peer-reviewed articles published in many different fields including psychology, architecture, nursing to gerontology. Results: The review found studies that identified environment-related factors, affecting wandering for people with Dementia living in Long-term Care Facilities. Implications: The findings can help us understand wandering behavior and the recommendations in this research can serve as parts of considerations in practice that can help efficiently manage wandering abilities of people with dementia living in Long-term Care Facilities. Further studies with larger samples and various environmental conditions are required to confirm the findings in this study.

According to the 2005 Korean census, the 65 and over population now exceeds 9.5% of the total population and is growing rapidly. Meeting elderly environment and care needs of this rapidly growing segment of the population becomes a major challenge for public policies and planners. Since great deal amount of elderly will reside in their houses, aging in place concept becomes important. For the success of aging in place, the quality of individual house unit, community support systems, and quality of senior center of the community are crucial. Since elderly environments and facilities serve not only medical and/or care programs but also social activity program in aging society, senior centers need to promote social activities and other care programs. The purpose of this study is to analyze characteristics of environmental affordance of a well received senior center in Tokyo, Japan. In order to analyze the characteristics, Murtha & Lee user benefit criteria and Lawton's environmental affordance approaches were used. As results, design characteristics and interior elements which provide environmental affordance were enumerated by type of space. Based on needs and user benefit criteria, those features were analyzed. This study shows design characteristics, elements, and attributes which are well received and utilized by elderly users.

본 논문은 의료 영상을 효과적으로 분류하고 검색 하기 위한 새로운 알고리즘을 제안한다. 의료 영상 중 X-Ray 영상은 어두운 배경에 반해 밝은 전경을 갖고 있기 때문에, 전경의 두드러진 부분에서만 시각 기술자로 추출한다. 우선, 색 구조 기술자(H-CSD)에서 해리스 코너 검출기로 검출한 관심 포인트들에서 색상 특징을 추출하고, 경계선 히스토그램 기술자에서 영상의 전역 및 지역적 질감 특징을 추출한다. 추출된 특징 벡터는 멀티클래스 SVM 에 적용되어 각 영상을 위한 멤버십 스코어를 얻는다. 이후, H-CSD와 EHD 에 대한 SVM 의 멤버십 스코어를 앙상블 결합하여 하나의 특징 벡터로 생성하고, K-nearest Neighborhood 방법을 이용하여 상위-K 개의 영상을 검색을 하도록 하였다. imageCLEFmed2007 을 이용한 실험 결과에서 다른 전역적 속성 또는 분류 기반 검색 방법에 비교하여 보다 개선된 검색 성능을 나타냄을 확인하였다.
