In adaptive designs important components of clinical trials may be changed based on the results of interim analysis. Several international guidelines point out that such interim analysis should be performed by independent experts who do not participate in clinical trials when adaptive designs are used in therapeutic confirmatory clinical trials, and if not, it may cause bias. The international guidelines recommend the establishment of independent data monitoring committee for conducting interim analysis independently.

Students enrolled in Department of Radiologic Science were surveyed on satisfaction of clinical practice. Purpose of the survey was to cultivate field-oriented talents capable of changing medical environment. Total 302 students in three-year and four-year school system were surveyed withSPSS/PC+ Win 13 version. Firstly, frequency analysis was used for distribution of general characteristics and clinical practice characteristics. Secondly, one-way analysis of variance was used to identify difference in the level of satisfaction based on variables. Thirdly, simple product-moment co-relation was used to analyze relations between variables. Among other variables, which include support to clinical practice class, instructors' expertise, practice subjects, practice environment, practice time, evaluation after practice and overall practice, students were most satisfied with overall practice, which was followed by practice subjects and time. This indicates high co-relation between factors affecting satisfaction of clinical practice education.

Quantitative electroencephalography (QEEG) has been widely used in research and clinical fields. QEEG has been widely used to objectively document cerebral changes for the purpose of identifying the electrophysiological biomarkers across various clinical symptoms and for the stimulation of specific cortical regions associated with cognitive function. In electroencephalography (EEG), the difference in quantitative and qualitative analyses is discriminated not by its measurement methods and relevant clinical or research environments, but by its analysis methods. When performing a qualitative analysis, it is possible for a medical technologist or experienced researchers to read the EEG waveforms to exclude artifacts. However, the quantitative analysis is still based on mathematical modeling, and all EEG data are included for the analysis, leading the results to be affected by unexpected artifacts. In the hospital setting, the case that the medical technologists in charge of the EEG test perform academic research has been little reported, compared to other clinical physiological measurement-based research. This is because there are few laboratories specialized in clinical physiological research. In this respect, this study is expected to be utilized as a basic reference material for medical technologists, students, and academic researchers, all of whom would like to conduct a quantitative analysis.

In this study, forest types in Chungheongnam-do were analyzed using Landsat satellite images and digital forest type map as a means to estimate forest carbon stocks. NDVI and Tasseled Cap, ISODATA, and supervised classification among others were used to analyze the forest types. The forest carbon stocks of Chungcheongnam-do were estimated utilizing forest statistical data derived from the classified results. The results indicate that the analysis of forest types through supervised classification yielded the highest overall accuracy in analyzing forest types using satellite images. Coniferous forests(49.3%) accounted for the highest proportion in all the forest types of Chungcheongnam-do, followed by deciduous forests(28.0%) and mixed forests(22.7%). The results of a comparative analysis between forest carbon stocks estimates made using the modified digital forest type map and other estimation methods showed that the method using Tasseled Cap and unsupervised classification yielded the most similar forest carbon stock estimates. The most significant difference, though, was made when only the digital forest type map was used. It is expected that if carbon stocks are estimated by integrating satellite images and digital forest type maps in the future, more accurate results can be derived in estimating forest carbon stocks at a national level.

The purpose of this study is to empirically examine how much the electronic clinical trial data management system actually enhances its efficiency. While the development of clinical trial markets highlights the significance of data management with increasing rate of adoption of electronic systems, its effects have not been fully supported with rigorous evidences. Particularly, the adoption rate of electronic clinical trial systems is low in domestic clinical trials markets. This study attempts to analyze the effect of the systems for reminding the importance of e-data management in clinical trials. The measurement indicator is experimented with the time related data collected from a multi-center clinical trial case. The result showed that the speed of the electronic clinical trial processes can be improved. The implication of this study lies in its first attempt to empirically analyze the effect of electronic clinical data management systems. Furthermore, application of the indicator in conjunction with electronic clinical trial processes is expected to facilitate strategic data management.

This study was intended to investigate differences in the recognition of the importance and performance of clinical nutrition management by using IPA. For the study, 100 clinical nutritionists working at medical institutions were analyzed. In all 17 categories of nutritional management, significant differences were observed in awareness of performance and importance. The categories with the greatest difference in importance and performance awareness were the nutritionist's participation in clinical nutrition education and related job development activities(1.38), and the lowest categories were the provision of therapeutic meals(0.69). Since IPA analysis results showed that participation in clinical nutrition education and related task development were both low in importance and performance, it should be improved first. A way to improve is for nutritionists to receive internal and external education. Above all things, for effective treatment, policies to include clinical nutritionist in the category of medical personnel, and cooperation between the medical sector and nutrition service management are necessary.
