The purpose of this study is to probe into student teachers' understanding of mathematics content knowledge and to identify the features of knowledge which is required to be emphasized in the elementary teacher education. For this, student teachers attending teacher preparation courses in Korea and Hong Kong were interviewed on tasks encompassing the 'what', 'why' and 'how' aspects of elementary mathematics. It was found that for the student teachers in the sample, their understanding of the concepts behind elementary mathematical topics was not very thorough. They were unable to retrieve the advanced mathematics that they learned in their advanced mathematics courses. It is suggested that for student teachers in mathematics, it is essential that the advanced mathematics they learn be explicitly related to the elementary mathematics they have learned in school.

The prevention of cancer is one of the most important public health and medical practices of the $21^{st}$ century. We have made much progress in this new emerging field, but so much remains to be accomplished before widespread use and practice become common place. Cancer chemoprevention encompasses the concepts of inhibition, reversal, and retardation of the cancer process. This process, called carcinogenesis, requires 20-40 years to reach the endpoint called invasive cancer. It typically follows multiple, diverse and complex pathways in a stochastic process of clonal evolution. These pathways appear amenable to inhibition, reversal or retardation at various points. We must therefore identify key pathways in the evolution of the cancer cell that can be exploited to prevent this carcinogenesis process. Basic research is identifying many genetic lesions and epigenetic processes associated with the progression of precancer to invasive disease. Many of these early precancerous lesions favor cell division over quiescence and protect cells against apoptosis when signals are present. Many oncogenes are active during early development and are reactivated in adulthood by aberrant gene promoting errors. Normal regulatory genes are mutated, making them insensitive to normal regulatory signals. Tumor suppressor genes are deleted or mutated rendering them inactive. Thus there is a wide range of defects in cellular machinery which can lead to evolution of the cancer phenotype. Mistakes may not have to appear in a certain order for cells to progress along the cancer pathway. To conquer this diverse disease, we must attack multiple key pathways at once for a predetermined period of time. Thus, agent combination prevention strategies are essential to decrease cancer morbidity. Furthermore, each cancer type may require custom combination of prevention strategies to be successful.

Purpose: The aim of this study was to develop a new course entitled 'Clinical Research Management' to enhance nursing students' clinical competency in handling clinical trials. Methods: The goals and content of the existing current education program for clinical research professionals such as clinical research coordinators and clinical research associates provided by the Korea National Enterprise for Clinical Trials were analyzed to identify the core educational concepts. A focus group interview was performed to investigate essential competency levels for the professionals who were to begin their career in the area of clinical trials after graduating from the college of nursing. Through these initial processes, we identified the core competency required for clinical research professionals and the related course content. Goals and objectives based on the specified four competencies were set and confirmed by expertise review. Results: We developed a new course entitled Clinical Research Management, a 16-week elective subject consisting of various teaching and learning strategies based on four core competencies: basic knowledge on clinical trials, communication, risk management, and ethics. Conclusion: The results of this study will contribute to enhancing nursing students' clinical competency, including knowledge, skills, and attitudes relevant to clinical trials.

The criterion of 'void space' in this paper is based on the sense of unusual experiences to afford the improvement of the value of cultural life with the sense of Healing. The more chances to spiritual converse with nature and oneself, the higher the value of healing experiences that one has will grow. This analysis has been done on the premises that this is derived from the inner conversation with 'nature' and 'oneself', as well as among 'others'. In other words, while the 'community void' affords programmatic aspect in relations between humans, the 'ecological void', systemic aspect in relations between human and nature, the 'meditation void', the aspect of image in relations between human and human's inside. Jong-soung Kimm and Hyo-sang Seung are Korean architects who have consistently expressed contrastive essential characteristics of the 'void space' in their contemporary works. While the void space of contemporary Korean architectures have shown various external forms, there has been a trace deeply rooted from the absolute and neutral concepts of the masters of Modern architects and 'Madang'of Korean traditional space. The integrated composition in the works of Jong-soung Kimm suggested integrated characters and healing affordances of 'Madang', but it hardly showed the poetic simplicity that could be seen from the image of traditional 'Madang'. On the other hand, the works of Hyo-sang Seung represented the simple and silent image of 'Madang', but showed fragmented characteristics that didn't sufficiently afford the integrated healing functions of 'Madang'.

International organizations related to air transport such as ICAO, IATA, ACI are forecasting that the number of passenger will grow about 4.4% annually up to 2015. Therefore, the innovation of given system technology and operation procedure is required in global scale to cope with the increase of air traffic demand. CNS/ATM infrastructure based on satellite is considered to play key role in order to solve the problems due to the dramatic increase of air traffic demand over the world. Free flight concept in the air transport operation has been proved with CNS/ATM infrastructure especially in USA and Europe. Therefore, it is necessary to develop key technologies to overcome technology gap and to secure international competitiveness in Korea. ADS-B is an important issue, and new element technologies should be considered as essential items which were shown in Capstone project. Nowadays, the free flight concept is combined to Air Transport Road Map such as NextGen project in USA, SESAR in Europe. In this process, free flight is included in the concepts such as ATM(Air Traffic Management), aviation security and safety, environmental protection and economy development, wide area weather variable reduction service, information integration and application between the related authorities (civil/military) etc. The purpose of research is to establish mid-term and long-term infrastructure plan and strategy for free flight realization in Korea. The analysis of action target and equipment construction status, phase construction plan of infrastructure has been performed by considering mid-term and long-term free flight plans of USA and Europe.

3D models in urban areas are essential for a variety of applications, such as virtual visualization, GIS, and mobile communications. LIDAR (Light Detection and Ranging) is a relatively new technology for obtaining Digital Terrain Models (DTM) of the earth's surface since manual 3D data reconstruction is very costly and time consuming. In this paper an approach to extract ground and non-ground points data from LIDAR data by using filtering is presented and the accuracy for generating DTM from ground points data is evaluated. Numerous filter algorithms have been developed to date. To determine the performance of filtering, we selected three filters which are based on the concepts for height difference, slope, and morphology, and also were applied two different data acquired from high raised apartments areas and low house areas. From the results it has been found that the accuracy for generating DTM from LIDAR data are 0.16 m and 0.59 m in high raised apartments areas and low house areas respectively. We expect that LIDAR data is used to generate the accurate DTM in urban areas.

Gist-based message design is essential in the Internet in which a lot of health messages are created and shared constantly. This study intended to identify the characteristics of health messages in a webzine and explore a way to design gist-based health messages. A total of 72 webzine articles published in Korean Ministry of Food and Drug Safety were selected, and text and visual messages of the articles were analyzed in terms of content types, the frequency and position of gists, and intuitive expression. The articles were also categorized regarding the characteristics of health messages through cluster analyses. This study found that most texts of the health articles consisted of facts and methods, while most visual messages represented concepts. In addition, both text and visual messages had limitations in presenting a gist effectively. It was also necessary to explore an effective way to improve an intuitive understanding of jargon and quantitative information in health messages. Based on these findings, this study provided suggestions for the design of gist-based health messages in the Internet.

The purpose of this study is to introduce the new regional geography approaches that have been lively discussed in English speaking countries since 1980s. The discussion of the new regional geography is based on intellectual interchange between geographers and social theorists. The new regional geographers regard a space as a more active thing. A space is not a merely passive container. It is not a outer settings, but a essential dimention of the human being. The new regional geography has been discussed in four perspectives: structuration theory perspective, spatial division of lavour theory perspective, world-systems theory perspective, and post-poststructuralism perspective. The new regional approaches well provide a new direction to regional studies. However, it is so abstracted in concepts for the empirical examinations that it is necessary to introduce a meso-level of concept.

In this paper we have provided an extensive survey of the databases and other resources related to the current research in bioinformatics and the issues that confront the database researcher in helping the biologists. Initially we give an overview of the concepts and principles that are fundamental in understanding the basis of the data that has been captured in these databases. We briefly trace the evolution of biological advances and point out the importance of capturing data about genes, the fundamental building blocks that encode the characteristics of life and proteins that are the essential ingredients for sustaining life. The study of genes and proteins is becoming extremely important and is being known as genomics and proteomics, respectively. Whereas there are numerous databases related to various subfields of biology, we have maintained a focus on genomic and proteomic databases which are the crucial stepping stones for other fields and are expected to play an important role in the future applications of biology and medicine. A detailed listing of these databases with information about their sizes, formats and current status is presented. Related databases like molecular pathways and interconnection network databases are mentioned, but their full coverage would be beyond the scope of a single paper. We comment on the peculiar nature of the data in biology that presents special problems in organizing and accessing these databases. We also discuss the capabilities needed for database development and information management in the bioinformatics arena with particular attention to ontology development. Two research case studies based on our own research are summarized dealing with the development of a new genome database called Mitomap and the creation of a framework for discovery of relationships among genes from the biomedical literature. The paper concludes with an overview of the applications that will be driven from these databases in medicine and healthcare. A glossary of important terms is provided at the end of the paper.

Objectives: The purpose of this study is to consider the concept of Meridian Points(經穴) and to establish the directions in further research. Methods: First, based on the latest results from the researches of Meridian and Collateral(經絡), it was to infer the original concept of Meridian Points(經穴). Second, the meaning of Meridian Points(經穴) has been investigated and its directions in further research was studied founded upon Symbolic Mathematical Study(象數學). Results ＆ Conclusions : Firstly, Meridian Points(經穴) are considered to be the source of information that contains 365 numbers of human physiological information which includes physiological information of Viscera and Bowels(藏府) and Meridian and Collateral(經絡). Secondly, advanced researches are required further to clarify the meaning of Meridian Points(經穴) as Symbolic Mathematical Study(象數學) has established the systems of Meridian Points(經穴). In addition, the efficacy of each Meridian Points(經穴) needs to be revised through literature studies. Clinical studies are essential to practically verify the results from the former theoretical research. Thirdly, the contention to oppose the presence of Meridian and Collateral(經絡) and Meridian Points(經穴) was acknowledged to be incorrect. Lastly, for broadening the theoretical systems of Korean Medicine(韓醫學) with integration of Western scientific knowledge, a paradigm shift is necessary to revise the concepts of Viscera and Bowls(藏府), Meridian and Collateral (經絡) and Meridian Points(經穴) in Korean Medicine(韓醫學). In order to accomplish the shift, the ambiguity in theories of Korean Medicine(韓醫學) should be clarified through the study of Symbolic Mathematical Study(象數學).
