육상의 U-health서비스와 달리 해상이라는 특수한 지리적 요건으로 인해 사용 가능한 통신기술이 제한적이며, 선박이라는 특수한 공간에서 발생하는 진동과 소음 등 환경적 요소와 의사 및 의료팀의 부재에 따른 의료지식이 현저히 부족한 의료 관리자 및 일반인이 쉽게 시스템을 사용가능하도록 사용성을 고려하여 해상의 선박 및 플랜트 등에서 원격으로 의료서비스 지원이 가능하도록 해양환경에 최적화된 원격의료시스템을 개발하였다.

Though there were many research and development about telemedicine on land recently, not yet applied to that on the shore. In this paper, when emergency clinic situation were generated in a ship on shore, the telemedicine system was designed and implemented for transfer and clinic service to doctors on the land by measuring basic body signals of patients. Presently, wireless communication and inmarsat telephone are usually used by simple questions and clinic consults to remote doctors when emergency situation were happened in the ship. In this paper, the telemedicine system on the shore were developed for improving this problems by measuring patient's fundamental conditions such as the blood pressure, pulse, the respiratory condition, electrocardiogram, body temperature, patient image and sending these information to remote doctors on land for more accurate prescription. The developed system can supply the high level clinic service to emergency patients on the shore and cope with the emergency situation in ship.

일반 사용자가 현재 접할 수 있는 무선인터넷은 SMS를 활용한 문자 형식의 정보제공이 대부분이고 유선의 인터넷과 같이 멀티미디어 서비스 그리고 실시간 전송속도, 사용자 환경, 거기에 보안 서비스까지 유선의 인터넷 서비스와는 비교가 되지 않게 그 이용환경이 열악한 상황이다. 오늘날 원격 환경의 진료시스템이 개발되고 있는데, 이들 시스템은 미래의 원격진료 즉. 병원에 직접가지 않고 집에서 바로 혈압, 심박수 등을 검사 받을 수 있는 시스템 개발의 기본이 되고 있다. 그리고 정보통신의 발전으로 모바일 PC 즉, 개인 휴대용 단말기(PDA:Personal Digital Assistants)가 의료분야에서 PC를 대체하여 이동성, 편리성을 제공하는 전자 차트를 선보이고 있다. 그러나 PDA는 작은 몸체로 이동성 및 편리성 등이 PC보다 뛰어나지만 해상도가 큰 이미지, 높은 처리 속도를 요구하는 작업등을 처리하기에는 효율성이 낮은 문제점이 있다. 또한 정보를 공유 할 수 있는 데이터를 무선 환경으로 처리해야 하기 때문에 환자와 관련된 의료 영상 즉, MRI 사진이나 X-ray 사진 등을 의료 환경에 이용하는 데는 보안의 문제점을 가지고 있다 따라서 본 논문에서는 매우 빠르게 발전하고 있는 진단과 치료기술을 이러한 의료를 필요로 하는 사람들에게 제공하는 접근성의 보장 문제를 해결할 수 있는 대안으로 무선 환경의 의료 인증시스템을 제안 하고자 한다.

육상과 떨어져 근무하고 있는 해양근로자들은 의료접근도의 한계성으로 인해 건강관리에 많은 어려움을 호소하고 있다. 이와 같은 해양근로자들에게 U- health기반의 해양원격의료시스템 도입을 한다면, 질병예방 및 건강관리, 나아가 건강증진에 이르기까지 매우 효과적일 것이다. 따라서 이 연구는 향후 해양근로자의 원격 건강관리 서비스를 위한 원격의료 도입 및 운영의 기본 방향을 제공하는 것을 목적으로 한다.

The purpose of this study is to design and implement a maritime telemedicine system to provide the best medical service for patients who rescue and happens in sailing ship. For this purpose, INMARSAT and MVAST, which are necessary communication channels for maritime telemedicine, were examined and diversity in maritime communication path was suggested. It was implemented to enable maritime telemedicine by linking smart devices and medical devices for physical examination. The marine telemedicine system adopts the HTTP communication protocol to configure the web server and process the client request. The patient's chart information was entered using an application for AndroidPad and the patient was diagnosed using Bluetooth electronic stethoscope for diagnosis. This system enables appropriate medical treatment to emergency patients at maritime, which ultimately can improve medical services. It is expected to be a more effective medical support system through linkage with various medical equipment.

Even in recent years, treatment of first-aid patients is still often delayed due to a shortage of medical resources in marginalized areas. Research on automating the analysis of medical data to solve the problems of inaccessibility for medical services and shortage of medical personnel is ongoing. Computer vision-based medical inspection automation requires a lot of cost in data collection and labeling for training purposes. These problems stand out in the works of classifying lesion that are rare, or pathological features and pathogenesis that are difficult to clearly define visually. Anomaly detection is attracting as a method that can significantly reduce the cost of data collection by adopting an unsupervised learning strategy. In this paper, we propose methods for detecting abnormal images on chest X-RAY images as follows based on existing anomaly detection techniques. (1) Normalize the brightness range of medical images resampled as optimal resolution. (2) Some feature vectors with high representative power are selected in set of patch features extracted as intermediate-level from lesion-free images. (3) Measure the difference from the feature vectors of lesion-free data selected based on the nearest neighbor search algorithm. The proposed system can simultaneously perform anomaly classification and localization for each image. In this paper, the anomaly detection performance of the proposed system for chest X-RAY images of PA projection is measured and presented by detailed conditions. We demonstrate effect of anomaly detection for medical images by showing 0.705 classification AUROC for random subset extracted from the PadChest dataset. The proposed system can be usefully used to improve the clinical diagnosis workflow of medical institutions, and can effectively support early diagnosis in medically poor area.

To create and maintain comparative supremacy as a strategic tool of business, many organizations have introduced informational technology and system. By using this system, Some companies got a beneficial value for achieving organizational goals but others could not obtain their effectiveness and efficiency. In particular, a lot of organizations that tried to make strategic supremacy with e-commercial trade are under hard condition because of poor profit. It implies that it is essential to identify and analyse the consumer who uses e-commercial trade. This paper, therefore, focusing on internet shopping malls between business and consumer as one of areas of e-commercial trades, shows the difference between consumer expectation and performance. The results of this study are as follows: First, as for the significant difference of influencing factors to consumer satisfactions according to the types of internet shopping malls, there is a meaningful difference in consumer anxiety and internet usefulness, but not in consumer service. Prior to verify the differences in detail on consumer's anxiety and internet usefulness, we examined that there is any difference between expectation and performance. T-test was used for the variants of consumer anxiety and internet usefulness, and its meaningful probability was 0.000, which means that both showed statistically significant difference. Based on the results, we also found that regardless of the types of internet shopping malls, consumer expectation was greater than performance. although the difference between expectation and performance was not equal according to the internet shopping malls. Second, a regression analysis was performed to understand the relation between consumer service, internet usefulness, consumer anxiety, and consumer satisfaction, it was found that consumer service, internet usefulness, consumer anxiety had significantly effected on consumer satisfaction. Third, To verify the relation between consumer satisfaction and repurchase-intentions, intentions to spread out, Pearson correlation analysis was used. it was found that consumer satisfaction had positive effect on both intentions. This study has some limitations because of the shorts of money and time. since the sample of this study was consumers who have ever bought one or more products via internet shopping mall, this sample was appropriate. but the major parts of sample were college students, and the sample size was so small. therefore this results should carefully be generalized. For further study, it is required to select more precise samples and to include more variables.
