치아는 식사 등의 일상생활에서 중요 역할을 하는 부위로 구강 건강을 지속적으로 관리하는 것이 중요하다. 최근 모바일에서는 의료 영상을 얻을 수 있을 만큼의 해상도를 갖춘 이미지를 얻을 수 있으며 디지털 의료기기로의 가능성을 보여준다. 본 연구에서는 스마트폰을 사용한 가시광선 영역의 파장대를 이용하여 치아의 초기 우식병소 진단에 도움을 받고 효율적인 관리를 할 수 있도록 하는 형광영상기반 치아분석시스템을 개발하였다. 시스템은 405 nm 파장대의 가시광선과 515 nm 이하의 단파장을 차단하는 필터를 고정하는 장치를 3D 프린터를 기술을 통해 고안 및 제작하여 스마트폰으로 치아의 영상을 얻고, 병소를 검출하여 정량적인 데이터를 제공한다. 제안한 시스템은 사용자의 시간적, 공간적 제약 없이 객관적인 데이터를 기반으로 사용자의 구강위생관리상태를 제시하여 조기진단 및 예방이 가능하다.

본 연구는 서울 열린데이터 광장의 공공 데이터를 활용하여 의료 복지 서비스 지원 방안을 조사한다. '올해 의료비로 인한 가계 부담 정도' 데이터를 분석하여, 의료비 부담이 일반 가구에 미치는 영향을 깊이 있게 조사하였다. 이 데이터는 응답자들이 느끼는 의료비 부담의 다양한 정도(전혀 부담 안 됨, 부담 안 됨, 보통, 약간 부담됨, 매우 부담됨)를 포함하고 있으며, 이를 통해 지역별, 성별, 연령별, 소득별 의료비 부담 차이를 분석하였다. 연구 결과는 각 그룹별로 상이한 의료비 부담감을 보여주며, 이는 향후 의료 서비스 접근성 개선과 정책적 지원을 위한 근거 자료로 활용될 수 있다. 본 논문은 의료비 부담을 완화하기 위한 다양한 정책 제안을 포함하며, 공공 데이터를 활용한 의료 자원의 최적화를 목표로 한다. 이러한 분석은 보다 효율적인 의료복지 서비스 제공에 기여할 것으로 기대된다.

Objectives: The purpose of this survey was to investigate the need for new medical devices based on opinions of members of the Korean medical society. Methods: We distributed two independent questionnaires sequentially over two-week intervals to 16,510 doctors via the Korean Medical Society, and received replies from 888 and 928 doctors, respectively. The survey was carried out through a web-based questionnaire system. The first questionnaire focused on demand for new diagnostic and therapeutic medical devices that are specific for Korean medicine (KM). In contrast, the second questionnaire focused on demand for new hybrid medical devices which are useful both in Western medicine (WM) and KM. Results: In purchase intention of Korean medical devices (KMDs), demand for diagnostic devices was greater than for therapeutic ones. Among diagnostic devices, the purchase intention of 'imaging devices' ranked the highest and was followed by 'musculoskeletal diagnostic devices'. Among therapeutic KMDs, the purchase intention of 'musculoskeletal treatment devices' ranked the highest, followed by 'cranial nerve rehabilitation devices'. In the purchase intention of hybrid medical devices that can be used both in WM and KM, 'ultrasonic-based medical device' ranked the highest, followed by 'MRI-based medical device'. Conclusions: There is increasing demand for clinically useful medical devices among Korean medical doctors. Within demand for new devices, hybrid devices that can be used in both WM and KM were most strongly desired. This survey will be useful in establishing strategic plans for the development of medical devices in KM. Keywords: Korean medicine, medical device, demand survey, questionnaire.

[ $Sr_2Ta_2O_7$ ], a layered perovskite compound, has been reported to possess most excellent photocatalytic properties among the layered perovskite materials. Recently, we have demonstrated that $Ba_5Ta_4O_{15}$ that was prepared under a mol ratio of Ba: Ta=1:1 has high photocatalytic performance as well as $Sr_2Ta_2O_7$. In this study, the photocatalyst samples with a mol ratio of Sr: Ba: Ta = (1-x): x: 1 were prepared. The maximum photocatalytic performance was obtained for x= 0.2, which is three times as high as that of undoped $Sr_2Ta_2O_7$.

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.

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.

Endoscope image is the shape that a doctor sees inside of patient through endoscope. The characteristics of these images are much effected by the light source of endoscope, specially areas in short distance from a light have much light source and look clear, but areas in long distance from a light look dark relatively because of little light quantity. So we developed a new level adaptive image enhancer for the dark area in a endoscope image. The algorithm we made consists of three parts ; 1) Classification of histogram in segmented area 2) Smoothing and Adaptive Histogram Equalization 3) Adaptive Histogram Modification.
