In this study, the purpose is to verified the feasibility to develope Hybrid x-ray detector in order to resolve problems of direct and indirect x-ray detectors. The properties of X-ray detector depend on absorption of X-ray, charge generation by x-ray photon, leakage current. In this study, CdS was used as photoconductor, and $Y_2O_2S:Tb$ as x-ray phosphor was formed on CdS in order to embody Hybrid structure. And Screen printing was used to form Muli-layer. Characteristics of this specimen were analyzed by using SEM, and XRD. And Photoluminescence spectrum of $Y_2O_2S:Tb$, leakage current, with respect to applied voltages, output charge with respect to applied voltages, and X-ray sensitivity were measured. Also, linearity with respect to dose was measured. Leakage current was similar with direct digital x-ray detector, but sensitivity of the hybrid structure is much better than the single-layer structure.

Post COVID-19, the medical legacy system will be transformed for utilizing medical resources efficiently, minimizing medical service imbalance, activating remote medical care, and strengthening private-public medical cooperation. This can be realized by achieving an entire medical paradigm shift and not simply via the application of advanced technologies such as AI. We propose a medical system configuration named "Medical AI Hub" that can realize the shift of the existing paradigm. The development stage of this configuration is categorized into "AI Cooperation Hospital," "AI Base Hospital," and "AI Hub Hospital." In the "AI Hub Hospital" stage, the medical intelligence in charge of individual patients cooperates and communicates autonomously with various medical intelligences, thereby achieving synchronous evolution. Thus, this medical intelligence supports doctors in optimally treating patients. The core technologies required during configuration development and their current R&D trends are described in this paper. The realization of the central configuration of medical AI through the development of these core technologies will induce a paradigm shift in the new medical system by innovating all medical fields with influences at the individual, society, industry, and public levels and by making the existing medical system more efficient and intelligent.

For the purpose of profound comprehension of the Current education of Oriental medical classics in Korea, I investigated the results of direct survey of the Current education of Oriental medical classics from each professor, and came to following conclusions. 1. The education of Oriental medical classics mainly lasts for 2 years. Students have average 6.59 hours of lecture every week. The rate of full service professor reaches 74.4%. But the department of Oriental medical classics in every college takes charge of many subjects which are related to Oriental medical classics, so the appointment of large number of full service professor is essential for the improvement of educational environment of Oriental medical classics. 2. After the publishing of the common textbook of Oriental medical classics, it gradually became the main textbook. But it is necessary that we should complement the textbook and it is also necessary that we should develop another textbook for Nangyeong(難經). 3. Most professors emphasize on the cultivation of the ability which enables Oriental medical thought through precise comprehension of original text. By the way, for the purpose of motivation of studying Oriental medical classics, it is necessary to develop a lecture which is related to clinical medicine. From the same context it is also necessary to read clinical original text such as Dongui-bogam(東醫寶鑑) and Uihakimmun(醫學入門) in class.

Purpose: This study was done to help provide patients with information on medical insurance cost through medical insurance education for nurses, to increase effective management, check on omissions in treatment and appropriateness and accuracy of fees, and to contribute to the economic growth of hospital by providing nurses with necessary knowledge about medical insurance cost. Method: The participants in this study were clinical nurses in general hospitals. The study instrument was a questionnaire developed by the researcher through reference to data for medical insurance education. The data were analyzed with percentages, means, ANOVA, and Duncan method using SPSS PC+10. Result: The results on knowledge of medical insurance according to general characteristics of the nurses showed that there were significant differences according to age: (p=.0036) highest level of education (p=.0007), position (p=.0010) and place where education on medical insurance was received (p=.0093). Conclusion: Continuous in-service education for clinical nurses is reflected in increased knowledge about medical insurance costs but special attention needs to be given to younger nurses and nurses with less education, as well as staff nurses, and those nurses who only received education on medical insurance during their schooling. Accordingly, in-service education is necessary for nurses at the time of orientation so that they have knowledge on standards for recuperation allowance, guidelines to calculate material costs, and guidelines to calculate drug rates. In addition, as medical insurance cost frequently change, all nurses need continuous in-service education.

The Korean people are all the beneficiaries of medical insurance or medical aid. It is important and needful to develop the preventive health program such as health examination and health education for disease prevention and health promotion of the beneficiaries. This paper diagnoses the status and problems of the current preventive health services to the beneficiaries and recommends how to develop the preventive health program in the medical insurance. This paper suggests that the government should strengthen the political support and supervision in order to develop the preventive health program in the medical insurance. In addition to the above suggestion, the following are recommended ; 1) to designate the large number of qualified hospitals for health examination. 2) to use the supplementary methods such as the health questionnaires in order to give the accurate health examination services. 3) to combine the health examinations by both laws of medical insurance and industrial health. 4) to arrange the manpower in charge of health education and to establish the health promotion centers. 5) to develop the effective mass media and materials for health education by use of TV, radio, VTR and slide projector.

This study analyzes the effects of hospital caseload on medical charges and length of stay for inpatients. Hospital caseload, representing the level of concentration of patients, was measured with the Internal Herfindal Index for three diagnosis related group (DRG) codes (appendectomy, operations on anus, and operations on uterus and adnexa). Ordinary least squares regression was used for analysis. Results showed that medical charges per inpatient and average length of stay significantly differed with respect to hospital concentration indices, and that hospital caseload was inversely related to operational performance for appendectomy and operations on uterus and adnexa. The significant negative relationship between concentration index and length of stay may decrease the total medical charges. The results imply that the expansion of the DRG payment system to hospitals will have a negative influence on their gross sales.
