Newly developed orthochromatic film HR series have many different types according to high speed, high resolution and special latitude. And now authors have practiced various screen-film combinations, those were usual regular type Fuji new RX film-LT screen and orthochromatic type HR films-rare earth G3, G4 screens. As a result of the experiment, we obtained high speed with high resolution and expansion of diagnostic range on the following combinations compared with usual new RX/LT series. Those combinations were RXO-G and HR-L films to skull, HR-G films to knee joint and hand part, HR-L film to abdomen. Therefore it may be desirable to select adquate kinds of HR series films according to investigated parts.

Objectives: The purpose of this study is to present the needs for New Health Technology in Korean medicine field and suggest the strategy to raise the application and selection rate. Methods: In this study, we reviewed the application status of New Health Technology application from April 27, 2007 to June 30, 2016. And we analyzed the assessment methods, procedures, and failure factors through the two Research stage technologies reports in Korean medicine field. Results: In Korean medicine field, the application status of New Health Technology is very small as 2% of the whole applications. Moreover, 62.9% of the applied technology were either an existing technology or an early technology, so did not enter the assessment process. Two technologies categorized as Research stage technology also had failed to adopt New Health Technology because they were lacking evidences or need more research to prove effectiveness. Conclusions: In order to develop New Health Technology in Korean medicine, more efforts should be made to activate research that can prove the safety and effectiveness of medical technology, and to create a quantitative or qualitative basis for the results of the research. Also, it is necessary to increase researchers' awareness of New Health Technology. And the strategy to positively utilize the "Limited Approval" to promote clinical studies.

Additive manufacturing (AM) is an alternative metal fabrication technology. The outstanding advantage of AM (3D-printing, direct manufacturing), is the ability to form shapes that cannot be formed with any other traditional technology. 3D-printing began as a new method of prototyping in plastics. Nowadays, AM in metals allows to realize not only net-shape geometry, but also high fatigue strength and corrosion resistant parts. This success of AM in metals enables new applications of the technology in important fields, such as production of medical implants. The 3D-printing of medical implants is an extremely rapidly developing application. The success of this development lies in the fact that patient-specific implants can promote patient recovery, as often it is the only alternative to amputation. The production of AM implants provides a relatively fast and effective solution for complex surgical cases. However, there are still numerous challenging open issues in medical 3D-printing. The goal of the current research review is to explain the whole technological and design chain of bio-medical bone implant production from the computed tomography that is performed by the surgeon, to conversion to a computer aided drawing file, to production of implants, including the necessary post-processing procedures and certification. The current work presents examples that were produced by joint work of Polygon Medical Engineering, Russia and by TechMed, the AM Center of Israel Institute of Metals. Polygon provided 3D-planning and 3D-modelling specifically for the implants production. TechMed were in charge of the optimization of models and they manufactured the implants by Electron-Beam Melting ($EBM^{(R)}$), using an Arcam $EBM^{(R)}$ A2X machine.

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.

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.

Recently, South and North Korea summits agreed to implement the cooperation and promotion of medical healthcare at the third inter-Korean summit in Pyeongyang on September 18, 2018. Therefore, the South Korean government and its affiliated organizations have been looking for ways to establish a specific plan for support and exchanges in the field of healthcare and medical technology. In the background of the above new policy, radiation medicine technology can also contribute to the exchange in the field of healthcare and science & technology for the peaceful coexistence of one Korea. In this review, we analyzed and showed the status of healthcare and radiation medicine infrastructure in North Korea in order to further develop a plan to share the benefits of radiation medicine with North Korea in the exchange of healthcare and science & technology.

인터넷을 통한 의료 마케팅은 전문성과 공익성의 문제로 소비자에게 어떻게 마케팅 활동을 펼칠 것인가 하는 문제가 제기되며, 모든 진료과목에서 동일하게 적용되는가, 혹은 진료과목의 특성에 따른 맞춤 전략을 세워야 하는가의 선택도 중요하다. 본 연구는 이 문제의 접근을 위해 인터넷 의료마케팅을 소비자들이 받아들일 것인가 하는 점을 비보험적용 진료과 목과 상대적으로 인터넷 마케팅 활동이 저조한 보험적용 진료과목들을 상황변수로 나누어 기술수용모델(TAM)을 통해 접근하였다. 본 연구 결과 비보험진료과목 의료서비스 마케팅 활동에 대해 소비자들은 용이성을 통해 유용성을 느끼며 그 결과 인터넷 마케팅을 받아들일 의도가 있고 더 나아가 만족한다는 것을 알 수 있으나 보험진료과목 분야의 인터넷 마케팅은 소비자들에게 유용성보다는 용이성이 마케팅의 수용의도에 우선적으로 영향을 미치고 있음이 밝혀졌다. 이를 통해 필수의료나 응급의료 부문을 담당하고 있는 보험적용 진료과목의 경우 공격적인 마케팅 활동 보다는 보다 더 소비자들이 유용성을 느낄 수 있는 마케팅 전략을 수립해야 하며 피부미용성형, 건강 검진, 건강증진 프로그램 등의 부문을 담당하고 있는 비보험적용 진료과목 의료서비스 제공자들은 마케팅 활동으로 시장 자체의 크기가 커질 가능성이 많으므로, 의료서비스의 전문성의 부각과 함께 서비스 자체의 이미지를 제고 시키는 마케팅 활동에 중점을 두어야 한다는 결론을 도출하였다.
