Purposes: The purposes of this study were to examine knowledge related to child abuse, attitudes toward child abuse, and intention to report child abuse and to identify the predictors of nurses' intention to report child abuse. Method: A descriptive-correlational study was conducted. Participants were 171 nurses who worked in the pediatric or emergency rooms in G city. Self-administered questionnaire was used for data collection. Descriptive statistics, t-test or ANOVA, Pearson correlation, and stepwise multiple regression analysis were used for data analysis. Results: Nurses had a limited knowledge related to child abuse. Nurses had negative attitudes toward child discipline, were inclined to punish the abuser, and had positive attitudes about professional responsibility for reporting child abuse. Nurses perceived difficulty in the actual behavior of reporting child abuse. Nurses' intention to report child abuse was predicted by nurses' attitudes to professional responsibility for reporting child abuse. Conclusions: Based on the findings of this study, educational programs need to be developed, implemented, and evaluated. The conclusion of this study is that supplementary education is needed for multidisciplinary decision making concerning the role of the nurses within the context of child abuse. Implications for nursing practice, education and research are discussed.

This paper examines the trends of recently developed human-care robots and social interaction technologies. As one of the solutions to the problems of an aging society, human-care robots have gained considerable attention from the public and the market. However, commercialized human-care robots do not meet user expectations for the role as companions. Current robot services based on short-term interaction and fragmentary pieces of intelligence have encountered difficulty in eliciting natural communication with humans. This results in the failure of human-robot social bonding. Social interaction is being actively investigated as a technique for improving robots' natural communication skills. Robots can form a natural bond with humans through social interaction, which consequently increases their effectiveness. In this paper, we introduce recent human-care robot-related issues and subsequently describe technical challenges and implications for the success of human-care robots. In addition, we review recent trends on social interaction technologies and the datasets required.

With the competitive pressure and the development of information and communication technology, many organizations have introduced various kinds of enterprise-wide systems like enterprise resource planning (ERP) systems as strategic tools for the purpose of improving organizational performance. Despite their promised strategic benefits, however, their implementation has suffered from a high failure rate and difficulty in realizing the anticipated benefits. Previous studies have indicated that one of the most critical failure reasons is the lack of knowledge sharing and utilization across organizations. As a consequence, many information systems (IS) researchers have paid attention to examining the effect of absorptive capacity closely associated with knowledge sharing and transferring on IS usage performance. ERP systems implementation involves changes not only in systems but also in processes and other social dimensions, which can be related to organizational citizenship behavior (OCB) requiring appropriate communications and interactions among organizational members. A lack of communications and interactions due to a lack of OCB might lead to weak absorptive capacity and thus negatively influence knowledge sharing across organizations, because OCB facilitates a successful collaboration among functional units and positively impacts individual's attitude toward radical organizational change. With this motivation, this study has two research objectives. First, it introduces and tests a theoretical model accounting for the relationships among performance of ERP system usage, absorptive capacity, and OCB. Second, it examines a mediating role of absorptive capacity between OCB and performance of EPR system usage. Theoretical and practical implications of the study ware discussed, along with its limitations.

This study was conducted to identify instructor's experience on simulation education. The subjects were nine instructors in simulation education of EMT students. Data were collected through documents and in-depth interview from participants. It was analyzed by phenomenological method, using Colaizzi's method. The results of this study were as a follows. From the protocol, significant statements were organized into formulated meanings. The formulated meanings were identified 28 themes, 9 theme clusters, and 4 categories. The 4 categories were as follows; discomfort of forming the learning environment; burden of instructor's role; difficulty from insufficient education condition; possibility of new education. This study suggested that improvement of simulation education can be accomplished by providing opportunities to learn the simulation technology, using the pre-programmed scenarios, having technical support from specialist or additional operator, and adjusting the current paramedic curriculum.

The purposes of this study were to investigate the creative science problem solving (CSPS) process amongst scientifically-gifted students and average students through the qualitative think-aloud research method, and to compare the differences in their CSP, scientific knowledge, scientific process skills, creative thinking, and finally, the affective domain used in their CSPS. For the purposes of this study, two scientifically-gifted 6th grade students and one average student were selected. The results show that one gifted student with good creative thinking skills exhibited better performance in CSPS than the other gifted student, who had the highest level of scientific knowledge. In the case of the average student, in spite of her high level of factual knowledge, she had difficulty in proceeding in CSPS due to her shallow scientific knowledge along with her low level of understanding of the given problem. This study highlights the importance of considering the factors which influence successful CSPS and which can play an important role in the education of scientifically-gifted children. These factors were identified as scientific knowledge, understanding of the scientific process, creative thinking, the affective domain, and science problem solving skills.

This study has examined how residents view the remodeling process of their old apartment and the actual conditions of apartment remodeling case in Yonggang-dong, Mapo-gu, Seoul, in Korea. The questionnaire survey has been conducted to apartment residents in Seoul who want to have their houses remodeled in order to specifically find out how they view remodeling process. Furthermore, interviews have been conducted with persons who were in charge of remodeling operations, and related data have been analyzed by conducting on-the-spot survey on apartment in Yonggang-dong. The major findings were as follows 1. The residents pointed out the biggest problem is the lack of information in the remodeling process. Therefore, education and PR on remodeling to residents should be kept on in order for them to play a key role in remodeling operation. 2. In Yonggang apartment remodeling process several problems have been found such as the difficulty of obtainning unanimous consent from residents, the lack of the active and positive participation of residents and the absent of the drawing. Therefore, to activate remodeling of the apartment complex, it needs not only to induce the residents to participate positively, but also to make a practical adjustment on current special repairing allowance.

Nanometal alloy catalysts have been found to significantly increase catalytic efficiency, compared to the monometallic counterparts. This enhancement can be attributed to various alloying effects: i) the existence of uniquemixed-metal surface sites [the so called ensemble (geometric) effect]; ii) electronic state changes due to metal-metal interactions [the so called ligand (electronic) effect]; and iii) strain caused by lattice mismatch between the alloy components [the socalled strain effect]. In addition, the presence of low-coordination surface atoms and preferential exposure of specific facets [(111), (100), (110)] in association with the size and shape of nanoparticle catalysts [the so called shape-size-facet effect] can be another important factor for modifying the catalytic activity. However, mechanisms underlying the alloying effect still remain unclear owing to the difficulty of direct characterization. Computational approaches, particularly the prediction using first-principles density functional theory (DFT), can be a powerful and flexible alternative for unraveling the role of alloying effects in catalysis since those can give us quantitative insights into the catalytic systems. In this talk, I will present the underlying principles (such as atomic arrangement, facet, local strain, ligand interaction, and effective atomic coordination number at the surface) that govern catalytic reactions occurring on Pd-based alloys using the first-principles calculations. This work highlights the importance of knowing how to properly tailor the surface reactivity of alloy catalysts for achieving high catalytic performance.

The coding of video sequences has been the focus of research in recent years. High Definition TV(HDTV), video conferencing and video on demand(VOD) are some of the well known applications. In the moving picture compression, motion estimation algorithm plays a very important role, but due to its high computational complexity, there has been many approaches to overcome this difficulty. We propose a new block matching criterion that uses modified cost functions. This new block matching criterion classifies pixels into 2-levels, 4-levels and 8-levels with a suitable thresholding method. We also show that our new proposed algorithms can easily be combined with many other fast motion estimation algorithms with good performance.

Human melanocortin-4 receptor (hMC4R) has a critical role in part of energy homeostasis, and their heterozygous mutations related in genetic cause of severe human obesity. In order to study the structure and function of these membrane proteins, it is important to prepare the samples. However, the preparation of transmembrane peptide is seriously difficult and time-consuming. Overexpression and purification of membrane proteins was reported to be difficult due to their innate insoluble and toxic properties. Among the many difficulties, the most important is the difficulty in obtaining sufficient quantities of purified protein. Recently, we succeed to produce large amounts of the second transmembrane domain from the wild-type hMC4R (wt-TM2) and D90N mutant hMC4R (m-TM2) and proposed the structural difference of them in membrane-like environments. In this paper, we demonstrate the optimization procedures to express and purify wt-TM2 or m-TM2 peptides, and solution NMR studies in different detergents to get high-resolution spectra were also described.

The surgical removal of solid deep-seated hemangioblastomas remains challenging, because treatment of these lesions is often complicated by severe bleeding associated with the rich vascularity of this tumor, and by severe neural tissue injury associated with the difficulty of en bloc resection, especially when the tumor is located at the cervicomedullary junction. Therefore, preoperative embolization of deep-seated solid hemangioblastomas may play an important role in successful surgical removal by reducing major bleeding and neural tissue damage. A 24-year-old woman, 28-weeks pregnant, was admitted to our hospital for the evaluation of quadriparesis, and brain magnetic resonance imaging[MRI] revealed intra-axial mass lesion in the cervicomedullary junction. After delivery, her neurologic symptoms became aggravated, and we decided to operate. Preoperative angiography revealed a hypervascular tumor in the posterior fossa, and embolization of the main feeding artery using gelfoam and microcoil, resulted in marked reduction of tumor vascularity. She underwent a midline suboccipital craniotomy involving the removal of the arch of C-1. The tumor was totally removed through a midline myelotomy, and at her 6-month follow-up she walked independently. We report on the combined use of the preoperative embolization of feeding vessels and subsequent operative resection in a patient with a solid hemangioblastoma at the cervicomedullary junction immediately after delivery.
