When participating in problem-based learning (PBL), it is important for medical students to generate claims and provide justifications for their claims in small group discussions. This study aimed to investigate the effect of argumentation instruction on medical student learning experiences with PBL. A total of one hundred first-year preclinical students from Inje University College of Medicine, who had attended argumentation instruction, participated in this study. All of the participants completed a 5-point Likert scale questionnaire regarding their learning experiences with PBL, before and after the argumentation instruction. The questionnaire comprised 22 items with eight subcategories: argumentation activity, reflection, integration of basic and clinical science, identification of lack of knowledge, logical thinking, self-directed study, communication, and attitude toward discussion. The collected data were analyzed through a paired-sample t-test. The results of this study found that the argumentation instruction promoted the preclinical students' experiences with argumentation activities, reflection, an integration of basic and clinical science, the identification of their lack of knowledge, logical thinking, and self-directed study, and it increased positive attitudes toward group discussion. The findings suggest argumentation instruction can enhance medical student group discussions and help students achieve the objectives of PBL, including acquisition of basic and clinical science knowledge and development of clinical reasoning and self-directed learning abilities, which can highlight the meaningful learning experiences students have with PBL.

Today, the medical information system has evolved in the way of integrated healthcare IT information systems. Therefore, it is trying to build advanced U-Healthcare service. Though the U-Healthcare environments is exchanged the information between systems in many cases, however since the each system is different, the integration and exchange of data is difficult. To overcome this problem, in this paper it proposes that we suggests a possible DBaaS(DataBase as a Service) for the heterogeneous integration of medical information management and data exchange. First, the proposed system builds DBaaS cloud by integrating the meta-DB Schema level and DB Schema for each hospital. And, the mapping the schema data and the existing hospital information system is possible using the International Standard HL7. By applying the proposed method to the hospital system, it comes true the efficient exchange of information between the patients, doctors, staffs through the data mapping of the one to multi-system.

This paper proposes a fuzzy correction algorithm that can correct the distorted medical image caused by the scanning nonlinear velocity of the Digital X-ray Scanner System (DX-Scanner) using the Multichannel Ionization Chamber (MIC). In the DX-Scanner, the scanned medical image is distorted for reasons of unsuitable integration time at the nonlinear acceleration period of the AC servo motor during the inspection of patients. The proposed algorithm finds the nonlinear motor velocity modeling through fuzzy system by clustering and reconstructs the normal medical image lines by calculating the suitable moving distance with the velocity of the motor using the modeling, acceleration time and integration time. In addition, several image processing is included in the algorithm. This algorithm analyzes exact pixel lines by comparing the distance of the acceleration period with the distance of the uniform velocity period in every integration time and is able to compensate for the velocity of the acceleration period. By applying the proposed algorithm to the test pattern for checking the image resolution, the effectiveness of this algorithm is verified. The corrected image obtained from distorted image is similar to the normal and better image for a doctor's diagnosis.

Health systems science (HSS) is recognized as the third pillar of medical education. alongside basic and clinical sciences. Today's physicians must also be systems thinkers who are able to discern how social, economic, environmental, and technological forces influence clinical decision-making. This study aimed to propose strategies for structuring an HSS curriculum that is tailored to the Korean healthcare and medical education context. First, the authors of this study conducted a survey to identify the present curricular contents of HSS related education at Korean medical schools. Second, a needs assessment was performed to determine the necessity of HSS competencies, as well as the prerequisites for the seamless integration of HSS into the existing curriculum. Third, literature reviews on HSS education at 14 US medical schools and expert consultations was conducted. We would like to propose a set of strategic approaches, classified into two levels: comprehensive and partial restructuring of the current medical curriculum to incorporate HSS. The partial restructuring approach entails a gradual, incremental incorporation of HSS content, while maintaining the current curricular structure. In contrast, a complete overhaul of the curriculum may be ideal to build HSS as the third pillar of medical education, but its feasibility remains relatively limited. The partial reorganization approach, however, has the advantage of being highly feasible. Collaborative efforts between professors and students are imperative to collectively devise effective methods for the seamless integration of HSS into the existing curriculum.

Recently, introduction of the hospital information system has remarkably improved the efficiency of health care services within hospitals. Due to improvement of the hospital information system, the issue of integration of medical information has emerged, and attempts to achieve it have been made. However, as a preceding step for integration of medical information, the problem of searching the same patient should be solved first, and studies on patient identification algorithm are required. As a typical case, similarity can be calculated through MPI (Master Patient Index) module, by comparing various fields such as patient's basic information and treatment information, etc. but it has many problems including the language system not suitable to Korean, estimation of an optimal weight by field, etc. This paper proposes a method searching the same patient using MRI information besides patient's field information as a supplementary method to increase the accuracy of matching algorithm such as MPI, etc. Unlike existing methods only using image information, upon identifying a patient, a highest weight was given to physical information of medical image and set as an unchangeable unique value, and as a result a high accuracy was detected. We aim to use the similarity measurement result as secondary measures in identifying a patient in the future.

In these days, HIS(Hospital Information System) raise the quality of medical services by effective management of medical records. As computing environment was developed, it is possible to search information quickly. But, standard medical data exchange is not completed between medical clinic and another organ so far. In case of patient transfer, past medical record was not efficiently transmitted. It be feasible treatment delay or medical accident. It is trouble that medical records is transferred by a person and communicate with each other. Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML. Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere. Form in system of company product, relative organs that handle bio-signal data is each other dissimilar and integration and to transmit to supplement bottleneck this research uses XML. In this study, it is discussed about sharing of medical data using XML web technology to standard medical record between hospital and relative organization The data structure model was designed to manage bio-signal data and patient record. We experimented about data transmission and all-in-one between different systems (one make use of MS-SQL database system and the other manage existent bio-signal data in itself form in file in this research). In order to search and refer medical record, the web-based system was implemented. The system that can be shared medical data was tested to estimate the merits of XML. Implemented XML schema confirms data transmission between different data system and integration result.

고선량률 근접치료에 사용되는 상업용 선원과 치료계획 시스템들은 AAPM TG 43에서 권고하는 점 및 선 선원에 의해 선량분포를 계산한다. 하지만, 근접치료용 선원에 대한 인체 내의 정확한 선량계산을 위해서 3차원 부피의 선원을 고려하는 MC 기반의 선량계산 방법이 필요하다. 본 연구에서는 microSelectron HDR Ir-192 선원을 작은 부분으로 분할하여 계산하는 미소선원 적분법을 이용하여 기하학적 인수를 계산하였다. 또한, 범용 방사선 수송코드인 MCNPX를 사용하여 30 cm 직경의 구형 물 팬텀 내에서 선원의 선량률을 계산하여 비등방성함수와 반경선량함수를 구하였다. 그 결과를 MC 기반 광자 수송코드인 MCPT를 사용하여 계산한 Williamson의 결과와 비교 및 분석하였다. 미소선원 적분법과 선 선원 근사법에 따른 기하학적 인수는 $r{\geq}0.5cm$에서는 0.2% 이내에서 일치하였고 r=0.1 cm일 때 1.33%의 차이를 보였다. 본 연구에서 계산된 비등방성함수와 반경선량함수가 Williamson의 계산된 결과의 차이는 비등방성함수의 경우 r=0.25 cm에 서 2.33%의 가장 큰 R-RMSE를 보였고 $r{\geq}0.5cm$에서는 1% 미만의 R-RMSE를 보였다. 반경선량함수의 경우는 r=0.1~14.0 cm에서 0.46%의 R-RMSE를 보였다. 미소선원 적분법과 선 선원 근사법으로 계산한 기하학적 인수는 $r{\geq}0.1cm$에서 잘 일치하지만 3차원의 Ir-192 선원을 적용하여 계산한 미소선원 적분법이 실제 기하학적 인수를 잘 반영할 것으로 생각된다. r=0.25 cm에서 비등방성함수를 제외하고는 MCPT와 MCNPX의 몬테칼로 코드를 이용하여 얻어진 비등방성함수와 반경선량함수는 각각의 몬테칼로 코드에 대한 불확실성 이내에서 잘 일치함을 확인하였다. 따라서 MCNPX 전산모사 결과를 통해 TG-43의 선량 계산식에 사용된 인자를 Williamson 등의 결과와 비교 및 검증함으로써, 추후 다른 종류의 선원에 대해서도 Monte Carlo 기반의 연구가 가능할 것으로 기대된다.
