MEMS(micro electro mechanical systems) is a technology for the manufacture hyperfine structure, as a micro-sensor and a driving device, by a variety of materials such as silicon and polymer. Many study for utilizing the MEMS applications have been performed in variety of fields, such as light devices, high frequency equipments, bio-technology, energy applications and other applications. Especially, the field of Bio-MEMS related with bio-technology is very attractive, because it have the potential technology for the miniaturization of the medical diagnosis system. Bio-MEMS, the compound word formed from the words 'Bio-technology' and 'MEMS', is hyperfine devices to analyze biological signals in vitro or in vivo. It is extending the range of its application area, by combination with nano-technology(NT), Information Technology(IT). The LOC(lab-on-a-chip) in Bio-MEMS, the comprehensive measurement system combined with Micro fluidic systems, bio-sensors and bio-materials, is the representative technology for the miniaturization of the medical diagnosis system. Therefore, many researchers around the world are performing research on this area. In this paper, the application, development and market trends of Bio-MEMS are investigated.

Human fungal infections are uncommon in normally healthy persons, being confined to conditions such as candidiasis (thrush) and dermatophyte skin infections such as athlete's foot. However, in the immunocompromised host, a variety of normally mild or nonpathogenic fungi can cause potentially fatal infections. Furthermore, the relativeease with which people can now visit 'exotic' countries provides the means for unusual fungal infections to be imported into this country. Mycoses appear in many different forms and areas. Fungal infections or mycoses are classified depending on the degree of tissue involvement and mode of entry into the host. These are Cutaneous, Subcutaneous, Systemic, and Opportunistic. Cutaneous mycoses specially appears symptoms on the skin. They are treated by amphotericinB, nystatin, grycelfulvin, micronazole and ketaconazole, etc, but these medicines are been careful about using, because most of them have serious side effects and toxicities. So, on the purpose of finding safe novel medicines, we have researched oriental medicines and search them to treat mycoses. In oriental medicines treating mycoses, we pay attention to orient applications that directly have an effect on disorder lesions. Oriental applications consists of various herbs and have a lot of forms, so we try to classify them as herbs and forms

의약품의 치료 효과와 유사한 치료활성 기능을 갖는 화장품(코스메슈티컬)의 개발이 증가함에 따라 화장품법에서 규정한 기능성 화장품의 용도인 피부 미백, 주름개선, 자외선 차단 또는 피부를 곱게 태워주는 기능이외의 항염증, 탈모 방지, 비만 개선 등과 같은 의약품의 치료 효과와 차별화되지 않는 다양한 기능을 화장품의 용도로서 특허청구범위에 기재하여 특허출원하는 경우가 증가하고 있다. 그러나 상기와 같은 의약품의 치료 효과와 차별화되지 않는 기능을 화장품의 용도로서 화장품 발명에 기재한 경우 특허요건 판단에 있어서 심사과 및 심사관에 따라 차이를 보이고 있어 심사의 일관성에 대한 요구가 제기되어 왔다. 위와 같은 요구에 부응하기 위하여, 본 논문에서는 국내 기능성 화장품의 특허등록 현황, 심사관들의 견해 및 미국, 유럽, 일본의 화장품 관련 발명의 심사 실무를 파악하여 일관성 있는 특허 심사를 위한 대응방안을 제시하고자 하였다.

Nowadays, the whole world is putting in the knowledge information society by the internet which is connecting the global network. The internet enable us to see the life of the other people in real time. Most of health care professional obtain and update their new knowledge and skills through continuing education. EMTs who works five or ten shifts per day are not easy to attend continuing education session usually offered during their off-times. One of solutions to this problem would be to develop a education program which does not limit time and place. There has been increasing interest in the use of computers in medical education, but all designated facilities and teachers have no sufficient preparations for the education and training of EMT. There has been less attention to the rationale for the use and selection of applications. This article discusses an approach to the selection of medical informatics applications for the undergraduate medical curriculum. The aim of this study is to develop and evaluate a web-based continuing education program, to help EMT improve their knowledge of transfusion therapy and medical law, and to enhance their ability to contribute to the quality of patient care. The program generally was well received by EMTs. The program is a useful adjunct to the existing continuing education program. It also could be used in EMT student education and other health sciences.

Background : The purpose of this study is to review our experience with the variable applications of the facial artery muscolomucosal(FAMM) flap for oral cavity reconstruction following treatment for head and neck malignancies. Methods : We performed retrospect medical record review from January 2012 to June 2013. This flap technique was applied in 3 patients to reconstruct the defects of oral cavity induced by treatment for head and neck malignancies. Results : The defects and fibrosis occurred due to variable causes related to previous treatment for head and neck malignancies such as tumor resection and chemoradiation. Two patient suffered from defect on hard and soft palate and one patient suffered from trismus related to fibrotic scar band. We performed oral cavity reconstruction using FAMM flap even though these all patients had history of neck dissection surgery or radiation therapy. Conclusion : FAMM flap is an ideal option for reconstruction following treatment not only for primary tumor resection but also for defects induced by variable causes. Preoperative radiation and neck dissection surgery, which are previously considered as some challenges, are no longer contraindication in our cases.

In this paper, we propose a downlink power control scheme to apply in the unequal error protection multi-code CDMA mobile medicine system. The mobile medicine system contains (i) blood pressure and body temperature measurement value, (ii) ECG medical signals measured by the electrocardiogram device, (iii) mobile patient's history, (iv) G.729 audio signal, MPEG-4 CCD sensor video signal, and JPEG2000 medical image. By the help of the multi-code CDMA spread spectrum communication system with downlink power control scheme and unequal error protection strategy, it is possible to transmit mobile medicine media and meet the quality of service. Numerical analysis and simulation results show that the system is a well transmission platform in mobile medicine.

NIRS (Near-infrared Spectroscopy) and DOI (Diffuse Optical Imaging) are relatively new, non-invasive, and non-ionizing methods that measure or image optical properties (Scattering and Absorption Coefficient) and physiological properties (Water Fraction, concentration of Oxy-, Deoxy-Hemoglobin, Cytochrome Oxidase, etc) of biological tissues. In this paper, three different types of NIRS systems, mathematical modeling, and reconstruction algorithms are described. Also, recent applications such as functional brain imaging, optical mammography, NIRS based BMI (Brain-Machine Interface), and small animal study are reviewed.

In this paper, two kinds of advanced powder processing techniques Metal Injection Molding (MIM) and Direct Laser Forming (DLF) are introduced to fabricate complex shaped Ti alloy parts which are widely used for medical and aerospace applications. The MIM process is used to strengthen Ti-6Al-4V alloy compacts by addition of fine Mo, Fe or Cr powders. Enhanced tensile strength of 1030 MPa with 15.1% elongation was obtained by an addition of 4 mass%Cr because of the microstructural modification and also the solution strengthening in beta phase. However, their fatigue strength was lower compared to wrought materials, but was improved by HIP. Subsequently, the effect of feeding layer height (FLH) on the characteristics of the DLF compacts was investigated. In the case of 100 ${\mu}m$ FLH, surface roughness was improved and nearly full density (99.8%) was obtained. Also, tensile strength of 1080 MPa was obtained, which is higher than the ASTM value.

Covalent attachment of 1, 4-dimethylnaphthalene (DMN) based endoperoxide forming subunits to a polyvinyl butyral (PVB) backbone has been achieved. The functionalized polymer materials prepared and characterized here can serve as biocompatible carrier systems for studying cellular uptake, intermediate storage and delayed release of singlet oxygen, which opens up new doors for optimizing a variety of medical applications of photogenerated DMN-endoperoxides such as antiviral, antibacterial, antiplasmodial and antitumor activity.
