원적외선의 이용은 에너지절약을 목적으로한 효율이 높은 열전파형태로서 주로 응용되고 있다. 따라서 방사체의 적외선 방사특성과 피가열체의 적외선 흡수특성과의 관계가 먼저 명확하게 규명되어야 한다. 그러면, 그 흡수특성과 정합된 원적외선 방사세라믹스의 제작도 가능하게 되어갈 것이므로 원적외선의 작용효과가 각종 분야에서 이용되어 갈 것이다. 예를들면 의료분야에서 과거에는 인체의 일부를 가온할 필요가 있을 때에는 고주파전류, 마이크로파 또는 환부를 유동 파라핀속에 넣어 환부를 따뜻하게 하는 방법 등이 있지만 만약 어떤파장의 원적외선이 인체의 피부 깊숙이 투과가 가능하다면 마이크로파 방생장치 대신에 원적외선의 발생장치가 값이 저렴하고 기온부를 국소로 제한 할 수 있으므로 널리 사용되어질 것이다. 또 식품분야에서는 에너지절약의 관점에서 뿐만아니라 조리의 관점에서도 원적외선의 이용이 진전되어 갈 것으로 생각된다. 한편 원적외선센서의 진전은 놀랄만하여 앞으로 초전도세라믹스를 이용한 원적외선 검출의 죠셉슨센서는 더욱 진전되어 질것으로 생각된다. 어떻든 각종 원적외선방사 세라믹스의 개발과 원적외선 영역에서의 파장 특성에 대한 측정법이 확립되어짐에 따라서 원적외선 이용은 앞으로 각종방면에 진전되어질 것이다.

최근 의료, 보건, 헬스케어 분야에 대한 관심이 증가함에 따라 질병의 조기 진단 연구가 각광 받고 있다. 특히 표면증강 라만 산란 (Surface Enhancement Raman scattering)은 고분자 검출을 위해 가장 유용한 물리 화학적 기법으로 SERS를 활용한 특정물질 검출 기술 개발에 대한 연구가 많이 이루어지고 있다. 나노구조의 국부적 표면 플라즈몬의 공명조건 (Surface Plasmon Resonance, SPR)으로 유도된 전자기장은 우수한 SERS 신호를 나타낸다. 따라서 표면 플라즈몬 공명 효과는 귀금속 나노입자의 종류, 크기 및 형태, 기판의 형상 및 구조 등에 의해서 달라지게 되므로 이들을 조절하여 보다 민감한 SERS 신호를 얻을 수 있다. 본 연구에서는 고감도 SERS-Active 기판을 제작하기 위해 SERS 기판 표면의 나노구조를 최적화 하였다. SERS 기판 표면을 제어하기 위해 공정파워, 공정압력, 기판의 온도 등의 증착공정 변수에 변화를 주어 표면의 나노구조를 형성하였다. 이를 분석하기 위해 SEM 분석을 통해 피라미드형 실리콘 기판 표면의 Au 나노구조 금속 박막을 확인하였고, XRD를 이용하여 결정성 및 결정크기를 확인하였다. Rhodamine 6G를 이용한 라만 분석을 통해 SERS 신호의 강도를 알 수 있었다. 금속 나노구조의 형태, 온도 제어를 통해 SERS 신호강도가 우수한 나노구조 기판을 제조 할 수 있었다.

As the use of radiation for medical purposes increases, the exposure dose of medical workers is also increasing. To reduce this dose, various studies on changing the shielding material have been conducted. Recently, a new method to reduce the dose at the entrance of the radiation treatment room was proposed by using the photoelectric effect that occurs when the radiation is scattered. Because this method is particularly effective for low-energy photons, in this study, a slit-type structure was proposed as a excellent shielding structure against scattered x-ray in a general photography room, and was evaluated the shielding effect by Monte Carlo simulation. As a result of the calculation, this study found that in the case of a structure in which steel plates with a thickness of 2 mm and a width of 5 cm are stacked at 2 mm intervals, a shielding effect was approximately 99.9% or more, excluding the heights of the floor and the patient where scattering occurs directly.

In the tele-medical system, the broadband network for multimedia telecommunication and the multimedia terminal equipment for the remote access of the tele-medical information are essential. Especially, the tele-medical terminal equipment should provide the multimedia GUI environment in order to support the similar medical process by the tele-medical system. In this paper, we present a multimedia GUI (Graphic User Interface) for a Multimedia Tele-Medical System (TeleMedi_GUI) based on ATM/B-ISDN. In the tele-medical system, one workstation is used for the multimedia data server that is supporting multiple client terminals that are connected by the ATM network. The client terminals are based on Multimedia Personal Computers, and provide the remote access environment of the tele-medical database. We also developed the remote access protocols among the clients and the server to access multimedia medical information of the multimedia server. With using the TeleMedi_GUI, the doctors can examine and treat patients efficiently, using image data like X-ray/CT and voice data such as the S-ray diagnosis. The result of this paper can be applied to the following areas: 1) the implementation of the advanced medical service system interconnecting the small-scale health center and general hospitals, 2) the development of a fully computerized medical information system within the hospital.

Due to the concern of regional unbalance relating to healthcare resources, the government has set up a plan to expand public healthcare services and a policy to manage the supply of hospital beds. However, it is not clear what standards are needed to measure the degree of unbalance, and to what extent the gap needs to be narrowed. Unlike the previous methodology comparing the proportions of patients who move out from their administrative district to receive medical services, this study examines the inconvenience gap patients experience when they have to move out from their actual living area. The logit and multinomial logit models are employed. The regional unbalance decreases when the degree of movement is measured based on the living area. This result implies that essential standard for achieving regional balance relating to medical services need to be based not on the even distribution of medical resources, but the complications of regional people that require proper medical services.
