This research is studied for investigative purposes of preparation status for healthcare telematics service enforcement via making an analysis of understanding & expectation effect about healthcare telematics introduction. The study is investigated with two groups, professional medical persons (doctors, nurses, pharmacists) and medical demanders (customers), to analyze the recognition difference between two groups. Questions are carried in face to face interviews by using structured questionnaire & Delphi technique. The survey result shows medical demander's expectation level is higher than the other's at all items such as social changes, medical service provider, medical service users, national and government agencies, medical system suppliers.

As the concept of well-being has become proliferated and an aging society has set in, there is a great demand for checking health condition of oneself as needed. Therefore, there is a growing interest in ubiquitous health systems all over the world, which can monitor health condition of oneself and transmit the monitoring results to the related medical institutes anytime anywhere. In this paper, some activities of ubiquitous health system developments all over the world are surveyed, and Medical Telematics project, one of ubiquitous health system projects being carried out currently in Daegu area, is introduced. The Medical Telematics project in Daegu area is carried out as one of RIS(Regional Innovation System) projects. An regional university, medical institutes, Technopark, and regional companies are organized into a consortium in order to construct a testbed for ubiquitous health industry in the future.

통신(Telecommunication)과 정보과학(Informatics)의 합성어인 텔레매틱스는 ‘의료 텔레매틱스 (Medical Telematics 또는 Medical Informatics)’와 같이 응용분야에 따라 상이하게 정의되고 적용될 수 있다. 그러나 공통적으로는 원격 장치나 시스템 (remote devices or systems)을 모니터 링하고 조정하는 제반 응용분야에 적용되는 개념으로 볼 수 있다. 텔레매틱스 응용분야 가운데 교통 분야는 시장 규모가 가장 크고 급성장하는 분야로서 특히 차량과 관련된 분야는 자동차산업과 정보통신기술 발전에 편승하여 최근에 가장 각광을 받고 있다.

Many hospitals have been considering new technology such as wireless sensor network(WSN). The technology can be used to track the location of medical devices needed for inspections or repairs, and it can also be used to detect of a theft of an asset. In an asset-tracking system using WSN, acquiring the location of moving sensor nodes inherently introduces uncertainty in location determination. In fact, the sensor nodes attached to an asset are prone to failure from lack of energy or from physical destruction. Therefore, even if the asset is located within the predetermined area, the asset-tracking application could "misunderstand" that an asset has escaped from the area. This paper classifies the causes of such unexpected situations into the following five cases: 1) an asset has actually escaped from a predetermined area; 2) a sensor node was broken; 3) the battery for the sensor node was totally discharged; 4) an asset went into a shadow area; 5) a sensor node was stolen. We implemented and installed our asset-tracking system in a hospital and continuously monitored the status of assets such as ventilators, syringe pumps, wheel chairs and IV poles. Based on this real experience, we suggest how to differentiate each case of location uncertainty and propose possible solutions to prevent them.

Until recently the German and the South Korean medical associations reacted cautiously to the introduction of telemedicine between doctor and patient which is exclusively on the platform conducted. But the General Assembly of German Physicians voted to lift the ban on remote treatment with the amendment to Section 7 (4) MBO-Ä(Medical Association's Professional Code of Conduct) in 2018 and the situation has been fundamentally changed in Germany. From then until now 16 of 17 rural medical associations have changed their professional code to allow telemedicine. In addition the legislature started to prepare the basis for the introduction of the electronic health card (eGK) and the telematics infrastructure. So far, various laws such as Medicinal Products Act, Drug Advertisement Act and Social Code have been changed to support legalization of telemedicine and digitalization of health care. Unlike in Germany, the social circumstances such as excessive centralization of the big hospitals in Seoul and the resulting concern of small medical practices for profitability are the main obstacles to the introduction of telemedicine. However the German approach how to legalise the telemedicine and to prepare for legal and technical infrastructure is also interesting in South Korea. The discussions for and against the changes in the law and the telematics infrastructure attempted by the German government for several years indicate that not only lifting the ban on remote treatment, but also harmonization of all the related legal system could guarantee successful implementation of telemedicine.

A wireless LAN medical information transmission system is useful for patients who need mobility in a local area environment. This paper proposes a method using WLAN(wireless local area network) and implements a stand-alone system with MAC(meidum access control) layer protocol referenced IEEE 802.11 draft standard. The system consists of a 8bit-microprocessor which handles media access control protocol and a WL100(GEC Plessey) chip which takes care of phsical layer specific routines and uses a RF module DE6003(GEC Plessey). The major features of the implemented system are the CSMA/CA protocol used a consecutive DATA-ACK trasmission method which yields more effective bandwidth allocation for asyncronous traffic transmission and the modified PCF protocol for time-bounded traffic transmission, which operates in ad-hoc network topology apart from IEEE 802.11 draft standard confirm PCF mode operate in infrastruture topology.

Most open magnetic resonance imaging systems have used the planar gradient coils whose inductances were minimized through the magnetic energy minimization procedure in the spatial frequency domain. Though the planar gradient coils have smaller inductance than conventional gradient coils, the planar gradient coils often suffer from their poor magnetic field linearity. Scaling the spatial frequencies of the current density function designed by the magnetic energy minimization, magnetic field linearity of the planar gradient coils can be greatly improved with small sacrifice of gradient coil inductance. We have found that the figure of merit of the planar gradient coils, defined by the gradient strength divided by the linearity error and the inductance, can be improved by proposed technique.

The goal of enhancement is to improve the perceptual aspect and visual appearance of images for human viewers. The objectives of image enhancement vary according to its specific application and an image enhancement algorithms used for a specific objective may not be accepted in some other applications. In this paper we review some of conventional enhancement techniques, such as global histogram equalization(GHE), local histogram equalization(LHE), clipped histogram equalization(CHE). We also describe some modified version of these algorithms. The proposed method is to detect detail information. We distinquish edge from nonedge and apply histigram equalization respectively. Simulation results demonstrate the performance of the proposed method for medical image.

In this paper, linear octree is used to reconstruct and to modify the 3-dimensional image from 2-dimensional cross sections provided by computed tomography. Linear octree introduces a considerable data saving of the memory storage required by small computer system. This structure allows the hidden surface removal utilizing the spatial presortedness of hierarchical octree structure and implementation of graphical operations that include viewing transform and shading. An actual human organ is used to illustrate this technique and its implications for theraphy and surgical planning.
