Virtual view synthesis, which generates novel views similar to the characteristics of actually acquired images, is an essential technical component for delivering an immersive video with realistic binocular disparity and smooth motion parallax. This is typically achieved in sequence by warping the given images to the designated viewing position, blending warped images, and filling the remaining holes. When considering 6DoF use cases with huge motion, the warping method in patch unit is more preferable than other conventional methods running in pixel unit. Regarding the prior case, the quality of synthesized image is highly relevant to the means of blending. Based on such aspect, we proposed a novel blending architecture that exploits the similarity of the directions of rays and the distribution of depth values. By further employing the proposed method, results showed that more enhanced view was synthesized compared with the well-designed synthesizers used within moving picture expert group (MPEG-I). Moreover, we explained the GPU-based implementation synthesizing and rendering views in the level of real time by considering the applicability for immersive video service.

This study aimed to understand students' learning in elementary science classes in terms of participatory perspective. Participatory perspective is based on the participationist views on learning. Based on the participatory perspective, this study used two concepts of participationism: 'the changes of learning on commognition' of Sfard (2007) and 'the identity' of Wenger (1998/2007). Based on these concepts, four episodes of an elementary science class were analyzed. The results showed that students carried out their learning from objective-level learning to meta-level learning. And students defined who they are by identifying and negotiating scientific meaning during the learning. These results showed students become members of science community through their participations in science class.

In this study, the performance analysis was divided into the public sector and private business sector. The four perspectives of the BSC performance analysis for the private business sector can be applied to all of the enterprises as there are Logical Linkages between the four Perspectives. However, these can not be applied in the same way to the public sector. There is no Logical Linkage between public sector and private sectors. Therefore, since there is no Logical Linkage, the KIX project of the public sector has a constrained condition. With the internal and external perspective views, the BSC of the KIX identifies the quality(operation) factor, user(customer) satisfaction factor, and economic costs effects(finance) factor. Based on the linkage model in both the internal and external perspective views and the BSC performance analysis of these views, a performance analysis model was developed and then performance results were analyzed of the whole KIX project.

Purpose: To evaluate the precision of measurements of distances and angle in the cross-sectional views of linear tomogram of panorama and to assess the technique for visualizing the mandibular canal. Methods: Ten dry mandibles were radiographically examined with 3 continuous cross-sectional views of linear tomogram of panorama and 4 continuous computed tomograms. The distance between the superior border of canal and alveolar crest and the bucco-lingual width of alveolar bone at the level of the superior border of canal and the angle between the two lines above were measured. Measurements were performed by radiologist and implantologist group and compared with measurements on computed radiograms of the same areas. Results: The measurements differences for the distance of alveolar bone height between in panorama and in CT showed 0.9 mm±0.6 mm by radiologists and 1.3mm±0.8mm by implantologists. There was no statistically significant difference between two groups' measurements. The differences in measurements for the distance of alveolar bone width between in panorama and in CT showed 0.5mm±0.8mm by radiologists and 2.5mm±1.4 mm by implantologists. There was significant difference (P<0.05) between two groups' measurements. The average bucco-lingual inclination of alveolar bone above mandibular canal was average 95.8° in CT. The difference of measurements between two groups was average 1±0.9°. Three cross-sectional views of panorama could show that the mandibular canal crosses antero-lingually and slopes inferiorly from the posterior segment of the mandible. Conclusions: The measurements in the linear tomogram of panorama by radiologists gave the accurate values of the distances and the angle compared with the values in computed tomograms.

This article intends to provide a direction for reconstructing the national regime of archival appraisal in electronic record environments. Functional appraisal, which inevitably carries out for appraising electronic records, has defects in aspect of selecting archives important in a national point of views. To do so, this article discusses defects of functional appraisal, and then suggests the necessity of archival appraisal strategies that complements functional appraisal. To investigate this archival appraisal strategies, it analyzes Australia's Whole-of-Government Functional Analysis, United Kingdom's Acquisition Policy and Appraisal Policy, Germany's Cooperative Cross-Archives Appraisal and Canada's Macro Appraisal. Ultimately, this analysis is able to establish a base of the regime of archival appraisal which will harmonize primary value at current stage with secondary value at non-current stage in a national point of views.

In this study, the views and the meaning of nature between the Western world and East Asia were compared through literature analysis. In the West, it is recognized that nature and human beings are separate. Nature is understood as regular and rational. They, therefore, take the view of particle and mechanical theory. In East Asia, it is thought that nature and humans interact with each other, and take an attitude of compromise and tolerance. Since nature is recognized as an ever-changing being, they, therefore, take the position of wave theory. Scientific knowledge and concepts are accepted depending on the personal view of nature. In Korea, science education follows the view of modern western science without considering the personal pattern of cognition, though students can have various views of nature. The attitude is needed regarding the various viewpoints as rich resources in science and science education.

Nursing is a discipline that helps to understand human being, to mitigate pains in life by promoting and recovering health, and to study the basic principles in sustaining and preserving life. To understand man and thus to nurse, it is essential to take the way of life of the specific person, his/her ideas, and natural environment into consideration. This means, the temperament, geography, environment and society peculiar to Korea have formed its own culture distinguished from those of other people. Thoughts and philosophy develop as a products of the specific culture and society. Therefore, accurate understanding of the concepts of nursing in the traditional thoughts and philosophy is indispensible to define Korean nursing. Modern Korean nursing at first rooted in the westernized nursing and western nursing intervention has been applied ever since its introduction in the late 19th century under the paradigm of western natural science. However, Koreans in the past made use of alternative therapy which put its emphasis on the organic and holistic view of life as well as a means for traditional medicine and nursing. This alternative therapy has been largely ignored since the introduction of western medical science, and was considered something used only by the aged or the uneducated. Moreover, Health concerned practices and customary traditional therapy have been discarded in the clinical medicine as "unscientific" or "unsystematic". As described above, it is true that Korean nursing has developed in the quantitative aspect only adhering to western nursing intervention. Now it is the time to stop to hold ourself and to look back our past. To find and develop the originality of Korean nursing to cope with the globalization, it is necessary to rediscover nursing (alternative) therapy in Korean culture ignored so far. For this purpose, this study examines the oriental philosophy to explore alternative nursing theory now under development. Also it aims to present ways to apply alternative therapy to nursing education, research and clinical practices and ultimately to show the desirable direction of the nursing to go in the future. Yangsaeng theory of Taoism and Yin-yang, Oh-hang(five elements) and khi theory in Dongeuibogam which gave enormous influences on Korean medical culture and treatment together with Sahsang(four temperaments) emphasized in Dongeuisusebowon will be examined as conceptual framework. Concepts of nursing are categorized into views on each the universe, the human being and nursing. Views on human being is classified into subcategories of body, life, health, and disease. Also it emphasizes the necessity of including alternative therapy in nursing intervention. Views on the universe is classified into yin-yang, khi, and temperament. Nursing will be available anywhere and easily accessible with this new nursing intervention. Trying to give a new thoughts to all those traditional concepts and alternative therapy, this article suggests the necessity of developing original Korean nursing theory and nursing intervention.

The purpose of this study is to investigate pre-service elementary teachers' views of the law of action-reaction by examining their degrees of understanding and Typically-Perceived-Situations (TPS). Data were collected from 177 Grade 3 pre-service elementary teachers. The results of analyzing these data show: First, the participants did not sufficiently understand about the law of action-reaction, and their degrees of understanding were different depending on the situation provided in the questionnaire. Second, in relation to the TPSs of the law of action-reaction, the participants thought of irrelevant situations to the law of action-reaction such as "a situation generated by inertia" as well as commonly relevant ones such as "a person pushing a wall", and had somewhat biased TPSs in terms of 'action type' and 'result motion type' of action-reaction. Finally, several suggestions on the science education for promotion of understanding about the law of action-reaction were given.

Cervical cancer is one of the most frequent cancers in women worldwide. Persistent infection with a human papillomavirus (HPV) is the main cause for cervical cancer. Vaccination and Pap smear screening are the best methods for prevention of the disease. The objective of this cross-sectional study was to assess the knowledge and views of upper secondary school female students in Kuala Lumpur, Malaysia, toward prevention of cervical cancer. This study was conducted from April 2009 to September 2009 in 8 schools in Kuala Lumpur area using pre-tested and validated questionnaires. Results indicated that the respondents had low knowledge of cervical cancer and its prevention although the majority of students (80.4%) had heard about the disease. The level of knowledge of cervical cancr and its prevention was significantly higher among students from the science stream (p<0.001) compared to students from the art stream. Most students (69.3%) agreed to take the vaccination if the service was available in schools. A high percentage of students (82.2%) agreed that the vaccination should be compulsory to the students. In conclusion, most students had low knowledge of cervical cancer and its prevention but they had positive attitude toward vaccination and agreed that vaccination should be compulsory. Therefore, suitable educational programmes should be developed to improve the knowledge of secondary school students on the prevention of cervical cancer.
