전통적인 면대면 교수-학습 환경에 대한 대안으로 인터넷을 통해 학습자의 학습 환경을 촉진하고 지원하며, 학습자가 자기 주도적(Self-Directed)으로 학습하도록 도와주는 e-러닝이 빠르게 확산되고 있다. e-러닝이 활성화 되면서 관련 분야의 연구도 활발하게 진행되고 있다. 한국과 마찬가지로 중국에서도 e-러닝 분야가 급속하게 성장하고 있으며 특히 대학 고등교육을 e-러닝으로 실시하려고 노력하고 있다. 그러나 중국 대학이 e-러닝을 효과적으로 실행하는 비율은 한국보다 낮고 e-러닝에 대한 연구도 충분히 이루어지지 않고 있다. 이에 본 연구는 한국과 중국 간의 대학 e-러닝의 학습 성과에 영향을 미치는 학습자 특성 및 교수자 특성 요인에 대한 인식도 차이를 알아보고자 한다. 이를 통해 e-러닝을 활용하고자 하는 중국 대학이나 기업에 국가별 특성에 적합한 e-러닝을 도입, 활용, 확산 등에 관련된 유용한 시사점을 제공하고자 하였다. 본 연구는 김희정･이석준･김종인(2011)의 연구에서 제시한 e-러닝의 학습자 특성 및 교수자 특성 요인을 도출하여 한국과 중국의 인식도 차이를 분석하고자 하였다. e-러닝 학습 경험이 있는 중국 대학생을 대상으로 설문지를 이용하여 자료를 수집하였으며 총 94부를 분석하였다. 간단한 기초통계를 비롯하여 신뢰도 분석과 한국과 중국 간 차이를 분석하기 위해 독립표본 T-검정 실시하였다. 분석 결과 한국과 중국 간 e-러닝의 학습자 특성과 교수자 특성의 인식에는 모두 차이가 있는 것으로 나타났는데 총 22개의 세부 요인 중 12개의 요인에서 한국과 중국 간 인식 차이가 있는 것으로 나타났다. E-learning is spreading rapidly as an alternative for traditional face-to-face ‘teaching-learning’ environment and as a tool for helping learners to study in a self-directed way by promoting and supporting their learning environment through the Internet. As e-learning is vitalized, its relevant researches are also proceeding briskly. China, like Korea, is enjoying swift growth of the e-learning sectors and especially trying to universities educations with e-learning. However, the rate of Chinese Universities’ effective use of e-learning is lower than that of Korea, and their e-learning related researches are not being achieved enough. Hence, this study will examine the perception differences in characteristic factors of learners and teachers, which influence the universities e-learning’s learning achievements in Korea and China. This will be able to help provide Chinese universities or companies with useful implications regarding the introduction, application, and diffusion of e-learnings suitable for the country’s characteristics. This study tries to analyze the perception differences between Korea and China, by deducting the characteristic factors of e-learning learners and teachers suggested in the study by Kim Hee-jung, Lee Seog-jun, and Kim Jong-in (2011). The data was collected by questionnaires targeting Chinese universities students who were having experience in e-learning use, and a total 94 of them were analyzed. Including the reliability analysis with simple basic statistics, the study conducted independent samples t-test in order to make analysis for differences between Korea and China. The analyses results indicate that the perception differences of learners and teachers exist there in all sectors between Korea and China. Out of a total of 22 detail factors, it was revealed that 12 of them show the perception differences between Korea and China.

Background: Otitis media with effusion(OME) is one of the most common disease in childhood. Patient suffers from OME in many quarters. For example hearing loss, effects on speech, language, learning, behaviouralchanges etc. But the diagnosis of OME is difficult using only medical history and otoscopy. So, many other diagnostic tools are developed and tympanometry is one of them. When OME is treated by oriental medical Tx, tympanometry would be useful instrument. Objectives: To gain insight into the usability of tympanometry in F/U of OME treated by oriental medial Tx. Methods: Data was collected from 123 ears of 74 children who was treated by oriental medical Tx. Data includes sex, age, period of Tx, elapsed time to be improved, tympanograms and accompanied symptoms. The relationship between items was analysed by statistical methods. Results: There is no relationship between age, sex and period of Tx/elapsed time to be improved. When cough and phlegm is accompanied, the period of treatment and elapsed time to be improved are expanded. When improvement was seen on tympanogram, the period of treatment is expanded but the improvement was seen within 30days, the period of treatment is reduced. Conclusion: The application of tympanometry in oriental medical treatment of OME would provide us many informations about the status of patient so it will be helpful to predict the history of a case and to make a decision whether keep up treatment or not.

방사선치료계획시스템의 MU계산 결과를 포괄적이고 독립적으로 검증할 수 있고 빔데이터 관리를 위한 사용자 친화적인 프로그램을 개발하였다. 선량계산의 정확성을 향상시키기 위해서 축이탈 인자, 빔 경화효과, 비균질성 보정 등의 요소를 계산 알고리듬에 포함하였고 상시적 정도관리 결과로 측정된 빔데이터로의 경신이 용이하도록 하였다. 기준깊이, SSD 등의 측정조건이 다를 때에 보정하는 알고리듬을 구현하였다. 상용 스프레드시트의 워크시트 함수를 빔데이터베이스 접근에 사용하였고, Visual Basic for Application (VBA) 개발환경을 사용하여 graphic user interface (GUI)를 구현하였다. 프로그램의 정확도를 평가하기 위하여 동일한 빔 데이터를 가진 치료계획 시스템을 이용하여 213개의 경우에 대한 팬톰의 선량을 계산하고 비교하였다. 또한 3차원 입체조형방사선 치료를 받은 17명의 환자데이터로부터 108개의 MU계산 기록을 추출하여 본 프로그램에서 계산된 MU와 비교하였다. 가상의 팬톰을 대상으로 계산을 수행한 결과, 과도한 비균질 영역계산을 제외하면 계산된 MU가 치료계획시스템과 3% 이내에서 잘 일치하였고, 환자 데이터를 이용한 계산에서도 과도한 비균질 영역 계산을 제외한 모든 계산에서 최대오차가 5% 이하로 나타났다. VBA 및 Microsoft Excel 워크시트 인터페이스를 이용하여 임상에 이용될 빔데이터 자료의 자동 생성 및 빔데이터 비교 템플릿 등의 용이성이 판명되었다. 본 프로그램을 이용하여 치료계획시스템의 정확성을 포괄적으로 검증할 수 있으므로 치료계획시스템의 정도관리 및 환자의 독립적 선량검증을 효과적으로 수행할 수 있다. 빔데이터베이스 생성 기능을 이용하여 빔데이터의 주기적 관리 경신 및 대단위 빔데이터베이스의 모니터링을 효율적으로 수행할 수 있다. We developed a user-friendly program to independently verify monitor units (MUs) calculated by radiation treatment planning systems (RTPS), as well as to manage beam database in clinic. The off-axis factor, beam hardening effect, inhomogeneity correction, and the different depth correction were incorporated into the program algorithm to improve the accuracy in calculated MUs. A beam database in the program was supposed to use measured data from routine quality assurance (QA) processes for timely update. To enhance user's convenience, a graphic user interface (GUI) was developed by using Visual Basic for Application. In order to evaluate the accuracy of the program for various treatment conditions, the MU comparisons were made for 213 cases of phantom and for 108 cases of 17 patients treated by 3D conformal radiation therapy. The MUs calculated by the program and calculated by the RTPS showed a fair agreement within ${\pm}3%$ for the phantom and ${\pm}5%$ for the patient, except for the cases of extreme inhomogeneity. By using Visual Basic for Application and Microsoft Excel worksheet interface, the program can automatically generate beam data book for clinical reference and the comparison template for the beam data management. The program developed in this study can be used to verify the accuracy of RTPS for various treatment conditions and thus can be used as a tool of routine RTPS QA, as well as independent MU checks. In addition, its beam database management interface can update beam data periodically and thus can be used to monitor multiple beam databases efficiently.

The purpose of this study is to find a solution to effectively nurse elderly people in the aging society of next generation by analyzing relationship among the social problem of elderly people in the future society, their preferred life style, and their understanding level of an asylum for the aged. Data for this study were collected by questioning 316 persons(257 visitors at C University hospital and 59 residents in Chun - Ra Nam Do) from December 1996 to March 1997. The results were as follows: The assumption that an individual's preferred life style at old age depends on his /her understanding level of the social problem of elderly people was verified ($X^2=9.75$, p<0.00). The assumption that one's understanding of an asylum for the aged depends on his /her understanding level of the social problem of elderly people was verified ($X^2=4.40$, p<0.05). The assumption that one's understanding of an asylum for the aged depends on his/her pre-ferred life style at old age was verified($X^2=34.51$, p<0.01). Among those who want to live together with children when they get old, the following differences in their conception were noted: Elderly people who has lost his /her wife /husband should marry again(p<0.01). Children should take care of their parents(p<0.01). Children should live with their parents(p<0.01), A desirable living style for an elderly people. An undesirable living style for an elderly people. Among those who want to live alone when they get old, the following differences were observed: It is okay for children to live separately from their parents as long as they provide financial support(p<0.01). Any child, regardless of the distinction of sex or the order of birth among siblings, can take care of his/her parents(p<0.05), It is desirable for an elderly people to live alone (p<0.01). It is undesirable for an elderly people to live in an asylum for the aged(p<0.05). It was verified that those who view an asylum for the aged in a negative way believe that children should take care of their parents. Also, it was verified that those who view an asylum for the aged in a positive way believe that children should provide financial support to their parents even though they do not live together(p<0.01). Regardless of the subjects' opinions on seriousness of the social problem of elderly people, the assumption that any child, regardless of the distinction of sex or the order of birth among siblings, can take care of his/her parents was verified(p<0.01) (p<0.05). Regardless of the subjects' view on asylum for the aged, the assumption that it is undesirable place for an elderly people to live was verified (p<0.01). The assumption that one's understanding of an asylum for the aged depends on the distinction of sex among general characteristics such as sex, age, educational background, occupation, and religion was verified(t=-2.82, p<0.01). The assumption that an individual's preferred life style at old age depends on the distinction of sex among general characteristics such as sex, age, educational background, occupation, and religion was verified(t=l.68, p<0.l).
