The purpose of this study was to evaluate shade selection using conventional visual assessment in vivo natural teeth and porcelain-fused-to-metal (PFM) crown. Maxillary central incisors, lateral incisors and canines of one hundred twenty four college women were used as vivo natural teeth. Fifty one PFM crown for maxillary central incisor fabricated by dental laboratory were used as experimental materials. Using Vitapan Classical Shade Guides, shade selection of natural teeth was measured by each college woman and shade selection of PFM crown was measured by three ceramists with more than ten years career. Both natural teeth and PFM crown shade selection were measured through Shade Eye-Ex. From the shade selection comparing, following results were obtained. The results were as follows: 1. The shade matching identification of natural teeth between the shade selection using Vitapan Classical Shade Guides and the shade selection using Shade Eye-Ex was 27.4% in maxillary central incisor, 13.7% in lateral incisor and 18.5% in canine. 2. Among the shade selection of PFM crown by three ceramists, the shade evaluation of three ceramists were same only in ten cases. In twenty case, those of two ceramists were same. 3. The shade matching identification of PFM crown between the shade selection using Vitapan Classical Shade Guides and the shade selection using Shade Eye-Ex was 38.6% in average. These results suggest that the shade selection using conventional visual assessment should be dealt with care in clinic and need a credible method for shade matching color.

Adoption of RFID has become widespread including logistics, drug supply-chain, and healthcare. To adopt RFID, we need to evaluate performance and feasibility of RFID S/W such as EPC Information Service (EPCIS), which demands a variety of test datasets of RFID business events. This paper proposes a novel method for creating RFID business events dataset by means of the simulation of RFID infrastructure. Proposed model provides a flexible representation capability since this is based on well-known petri-net. In addition, it can also be useful when determining adoption of RFID as it supports simulation of RFID environment.

Since 2000, there have been many changes in the residential types, such as an intelligent apartment which integrates both resting space and production space with comfort able, pleasant and safe environments based on internet systems. As the result of the rapid decrease in the birth rate and the prolonged lifespan around the world, it is expected that we will enter into an aging society by 2026. With such the expected change in the living patterns, many issues concerning the increased number of the elderly people have emerged as major social problems such as changes of family formation, its function and values, responsibility of caring for the aged, health and medical care, habitation policies and so on, and it is required to reconsider the social awareness on the living qualities of each old person. However, we have not yet satisfied such requirements with appropriate policies for the improvement of the living environment for them. It is considered, therefore, that we need to develop a new tool that, according to our goals, can give us a broad understanding on several considerations in designing the future homes for the elder people, making it possible to check the process changed by residents' needs in real time and apply it immediately to the space. As we have seen, it is required that spatial design process and design methodology should be considered in designing the homes for the aged for the pre-occupancy design evaluation.

Purpose: This study was done to compare organizational commitment, job satisfaction and job stress according to nurses' adult attachment styles. Methods: Data were collected by self-report questionnaires measuring Adult attachment style, Organizational commitment, Job satisfaction and Job stress from a convenience sample of 253 shift nurses in a hospital. Results: There were security style (31.2%), dismissing-avoidance (18.6%), preoccupation (17.8%) and fearful-avoidance (32.4%) among 4 attachment styles in these shift nurses. Their organizational commitment level (M=3.2), job satisfaction (M=2.7) and job stress (M=3.3) were revealed. Subjects who were in security attachment style showed significantly higher scores of organizational commitment (F=5.09, p=.002) and job satisfaction (F=13.02, p<.001) than subjects in fearful-avoidance attachment style. Meanwhile, this study showed that subjects who were in fearful-avoidance attachment style recorded significantly higher scores of job stress than subjects in any other attachment style (F=3.15, p=.026). Conclusion: This study demonstrated a relevant difference in organizational commitment, job satisfaction and job stress in accordance with the attachment style of shift nurses. These results indicate the need for attachment promotion program for shift nurses. And nurses' attachment styles should be considered in future interventions to enhance quality of nursing care.

Foreign body ingestions pose a significant health risk in children. Neodymium magnets are high-powered, rare-earth magnets that is a serious issue in the pediatric population due to their strong magnetic force and high rate of complications. When multiple magnets are ingested, there is potential for morbidity and mortality, including gastrointestinal fistula formation, obstruction, bleeding, perforation, and death. Many cases require surgical intervention for removal of the magnets and management of subsequent complications. However, we report a case of multiple magnet ingestion in a 19-month-old child complicated by gastroduodenal fistula that was successfully treated by endoscopic removal and supportive care avoiding the need for surgical intervention. At two-week follow-up, the child was asymptomatic and upper gastrointestinal series obtained six months later demonstrated resolution of the fistula.

Human activity recognition is widely used in smart homes, health care and indoor monitor. Traditional approaches all need hardware installation or wearable sensors, which incurs additional costs and imposes many restrictions on usage. Therefore, this paper presents a novel device-free activities recognition system based on the advanced wireless technologies. The fine-grained information channel state information (CSI) in the wireless channel is employed as the indicator of human activities. To improve accuracy, both amplitude and phase information of CSI are extracted and shaped into feature vectors for activities recognition. In addition, we discuss the classification accuracy of different features and select the most stable features for feature matrix. Our experimental evaluation in two laboratories of different size demonstrates that the proposed scheme can achieve an average accuracy over 95% and 90% in different scenarios.
