Recently, researches for the integration and standardization of clinical data in the Western medicine and Korean medicine is in progress. If an integration of similar clinical data as well as heterogeneous clinical data is possible based on one standardization, we can able to derive implicit medical knowledge from integrated clinical data. In this paper, we implemented Korean clinical database based on internationally known CDISC standardization to efficiently store Korean clinical data and constructed E-CRF system for convenient data input in clinical sites. Furthermore, we showed example of an integration of Korean clinical data from 4 clinical sites. The results of our study will help to establish the foundation for the extraction of implicit medical knowledge from integrated clinical data. Also, our results may support efficient management through data integration, prevention of repetitive or unnecessary clinical trials, facilitation of collaborative study and convenient research through the distribution of refined clinical data.

The purpose of this study is to evaluate and compare the quality of digital X-ray imaging system. The image quality evaluation was conducted By using Modulation transfer function indicating the quantitative resolution of the image and the noise power spectrum showing the noise characteristics. Using a IEC61267 radiation quality was applied to the geometry to be used in clinical and geometry presented in IEC62220-1 and Additional filter, grid, the clinical dose and the MTF value of edge phantom was measured. Result of the MTF corresponding to each item(Grid, Filter, SID, kVp, mAs), the clinical condition 100cm, 180cm, measurements of the spatial frequency of the MTF IEC62220-1Geometry 150cm became similarly apparent, rather spatial frequency was also the case high in clinical conditions 100cm. NPS results, as the dose(mAs) is increased, NPS showed that reduced. The image quality evaluation using IEC61267 the Radiation quality, Image quality of the video using the clinical conditions Geometry than image quality evaluation using IEC62220-1Geometry was better. It shows that MTF and NPC in IEC and clinical condition were not significantly different. In order to apply the evaluation method of image quality applied with clinical conditions rather than the future method, to be presented evaluation of IEC standard, based on the results of the image characterization studies in this paper, the methods that shows good quality of spatial resolution and decrease NPS value as the least dose, used suitable parameters for whether or not using added filter, grid, change SID and clinical quality(kVp), dose(mAs) etc should be found. then It is believed to be able to properly maintain the actual quality of the image of the digital radiographic imaging system in clinical.

The purpose of this research is to analyze the psychological dynamics of the characters in the novel 'vegetarian' of the Han Gang and the relationship patterns in the system by applying object relation theory. 'Vegetarianism' has already been analyzed and reinterpreted in various angles, but if you look at it from the object relationship theory and the systematic perspective, you can understand the inevitable history of the generation through psychological analysis and relation dynamics of the person. First, we will analyze the psychological dynamics of the characters by analyzing the meanings and exploring the meaning with the object relation theory and concept. The psychological analysis and the search process of the characters based on the theory are enough evidence for the counselor to reinterpret the life story of the client in the future clinical scene. In addition, in order to realize ethical but practical clinical education, the field of clinical practice will be extended when analyzing the characters using art. It is suggested that the meaning search through various character analysis needs to be accumulated culturally.

임상도는 항공사진을 판독하여 얻어진 산림에 관한 정보를 지형도(1/25,000)에 도화 작성한 도면으로 전국 산림조사와 연계하여 10년을 주기로 순환제작 되며, 현재 제 4차 수치임상도가 제작 중에 있다 임상도는 여러 산림관련 주제도 중 가장 많이 활용되는 도면으로 산림 분야뿐만 아니라 다른 분야에서도 널리 활용되고 있다. 그러나 10년을 주기로 제작되므로 부분적으로 현실과 부합하지 않는 내용이 포함되어 있어 각종 계획수립 및 활용에 장애요인으로 작용하고 있다. 따라서 실제 임상정보를 획득할 수 있도록 지속적인 갱신이 필요하다. 그러나 임상도의 부분적 갱신을 위하여 별도의 항공사진을 촬영하는 것은 현실적인 어려움이 있으며, 최근 고해상도 위성영상이 활용 가능하게 됨에 따라 임상도의 갱신에도 활용될 수 있을 것으로 기대되고 있다. 본 연구에서는 고해상도 위성영상인 IKONOS를 이용하여 수치임상도를 갱신하는 방법을 제시하였다. 연구대상지는 제 4차 임상도의 수치화가 완료된 전라북도 완주 지역으로 1:25000 지형도의 도엽명 대아와 읍내의 일부지역이다. 영상자료는 2001년 8월 18일에 촬영된 IKONOS Multispectral 자료를 이용하였다. 영상의 기하보정을 위하여 RPC Model과 1:25000 수치지형도로부터 만들어진 DEM을 사용하였다. 기하보정된 영상을 이용하여 영상분할(Segmentation)을 실시하여 서로 중복되지 않는 동질한 지역으로 구분하였다. 이때 기존의 수치임상도를 Super-Object로 사용하여 영상을 분할할 때 형성될 수 있는 가장 큰 Segment로 제한하였으며 Super-Object의 경계를 벗어나지 않는 보다 작은 Sub-Object를 만들도록 하여 분할영상의 계층적 구조를 형성하였다. 어느 한 임상내에서 변화가 발생하면 변화가 발생한 지역은 변화가 발생하지 않은 지역과 서로 다른 분광특성을 나타내므로 별도의 Segment를 형성하게 된다. 따라서 임상도의 경계선으로부터 획득된 Super-Object의 분광반사 값과 그 안에서 형성된 Sub-Object의 분광반사값의 차이를 이용하여 임상도의 갱신을 위한 변화지역을 탐지하였다.

This study will be used as basic data to hold clinical training effective by researching and analyzing frequency, satisfaction and stress for the clinical practice of dental hygiene course students. The survey was undergone from Feb. 1, 2014 to Mar. 31 for 219 dental hygiene course juniors who had experienced clinical training in 3 year colleges located in Daejeon and Chungcheong Province. From the study, general and university hospital holds the highest satisfaction in clinical practice and dental offices in acquiring skills. Also, a significant difference is shown between the frequency and satisfaction according to clinical training sheets. The highest degree of stress is shown in dental offices for 'toothbrushing training and dental health education' and in general and university hospital for 'patient counselling'. Therefore, consideration should be made to establish the direction of education, standard criteria and evaluation method for student clinical training to raise its effectiveness.

Clinical Data Interchange Standards Consortium (CDISC) developed global and platform-independent data standards to improve ineffective processes of clinical trial studies. Regardless of its objective toward global cooperation, the current version of the CDISC standard cannot describe clinical trial data in various languages for multi-national investigators or reviewers. This problem applies not only to tabulated datasets in Study Data Tabulation Model (SDTM) but also to extensible markup language representation of the datasets in Operational Data Model (ODM) instances. In order to address this issue, we propose to extend the current version of SDTM and ODM to collect clinical data for multi-national clinical trials. SDTM needs to have new special-purpose domain for multi-language representation purpose. Additionally, ODM is recommended to extend its XML schema using subtyping or type inheritance mechanism respectively. Our extension of SDTM and ODM enable to represent any granule of study data tabulation model or XML data entities to describe in efficient languages. This result will contribute to collect multi-language data easily for multi-national clinical trials.
