The rapid growth of investments in mobile service to reach a large and growing body of customers, coupled with low communication costs, has made user acceptance an increasingly critical management issue. The study draws upon the task-technology fit (TTF) model as its theoretical basis and its empirical findings to pragmatically explain the key factors that affect the performance and user acceptance of mobile service in medical field. A total of 110 usable responses were obtained. The findings indicate that the task, technology, and individual user characteristics positively affect task-technology fit and mobile service usage. The task-technology fit and mobile service usage are the dominant factors that affect mobile service performance. The result points out the importance of the fit between technologies and users' tasks in achieving individual performance impact from mobile service in medical arena.

A new open structure of the bird-cage RF coil is proposed. By applying in-phase or out-of-phase voltage to the two terminals of the open bird-cage RF coil, desirable level of RF field uniformity has been achieved. Theoretical resonance frequencies of the RF coil has been obtained and compared with experimental ones. The quality factor of the open bird-cage RF coil has been found to be comparable to the one of the conventional RF coil.

The Graphical User Interface (GUI) software is developed for 0.3 Tesla Permanent Magnet Resonance Imaging (MRI) system and the state of art of designing GUI system is discussed in this paper. The Object-Oriented concepts are applied for designing GUI software utilizing Interbase ODBC Database layer. Also, Multimedia concepts such as voice, sound and music are integrated in GUI system to enhance the efficiency of MRI operation.

Open MRI is a new concept in clinical application of the MRI such as interventional study. Receiving RF coils used in the open MRI must have open structures to insure convenient manipulations fur the patient. In this paper, we presented experimental study fur open head coil suitable to 0.3 Tesla vertical field MRI system with its experimental results.

Managing electronic medical record is very difficult, because the currently electronic medical system is not designed standard that is uniform and proper. In this paper, in order to overcome this situation, we propose meta-data for the management of the electronic medical record as a single system. To this end, we first analyzed the research on electronic medical records and related standards. Second, we, on the basis of the analysis result, abstracted electronic medical record and entities related on electronic medical, and we designed an entity-relationship model. And finally, we have to complete the meta-data through the setting attributes in this entity-relationship model. Through this study, it was possible that we can complete metadata highly expressive medical records, and suggest an alternative for problem of current medical records systems.

The present study aimed to compare and analyze the particulars of and difference in medical expenses and their composition ratio for 2,026 patients hospitalized at 2 types of medical institutions (443 at a clinic and 1,583 at a hospital) in Jeonju-si, Jeollabuk-do under coverage of automobile insurance during 2009. From the analysis, it became evident that there were differences in individual characters of inpatients covered by automobile insurance, and details, composition and composition ratio of medical treatment for them depending on types of medical institutions. There was no difference, however, between the total and average medical expenses per capita even when markup rate was applied to the automobile insurance by types of hospitals. The ratio of radiotherapy and physical therapy in the composition of medical expenses was found to be extraordinarily high in clinics compared to that of hospitals. The composition ratio of the fixed cost including charge for hospitalization also turned out to be fairly high in all medical institutions.

Purpose: The study investigated the effects of self-directed learning, learning flow, and academic self-efficacy variables on academic achievement. Methods: This is a descriptive correlation study to understand the effects of self-directed learning, learning flow, and academic self-efficacy on academic achievement. Results: There is a significant positive correlation between the participants' self-directed learning, learning flow, academic achievement, and academic self-efficacy. Self-directed learning and learning flow influenced academic achievement, while academic self-efficacy was found to have a partial mediating effect. As indicated above, academic self-efficacy and self-directed learning were significant predictors of academic achievement. Conclusion: The study results can be used as basic data to conduct future studies. Furthermore, results can inform the development of educational programs that enhance self-directed learning, learning flow, and academic self-efficacy to improve students' academic achievement in the department of emergency technology.

The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice by instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min, correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=.000) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).

This paper describes the design guideline, methodology and general specification of the developed 12 channel interpretive electrocardiograph. The developed 12 channel electrocardiograph consists of main module, patient module, DSP module, interface module, power/battery module, TFT color LCD and thermal recorder. The control panel of the system has full keyboard, rotate/push button, function key and unctional indicators. The graphic user interface program conveniently allows user to record, setup, store, manage ECGs. A variety of system configurations give it ability to make user favorable environment. This system also has a resting adult's ECG analysis program. The developed system and program will be continusely evolved using a database of clinically correlated ECGs.
