스마트폰과 태블릿 PC같은 스마트 기기의 보급 증가는 원격의료 서비스 분야의 활성화에 커다란 영향력을 미치고 있다. 그러나 환자와 의사가 직접 대면하지 않고 네트워크에 연결된 스마트 기기를 통해 진료 행위를 할 경우, 환자와 의사간에 상호 인식과 인증 등과 같은 보안 문제가 해결해야 할 가장 큰 걸림돌로 여전히 남아있다. 스마트 기기는 이동성과 편이성이 뛰어난 반면 각종 보안 침해 위협에 상대적으로 쉽게 노출될 수 있다는 단점이 있다. 스마트 기기를 원격의료 서비스에서 안전하게 활용하기 위해 바이오인식 (Biometrics) 기술과의 용합 시도와 관련 표준화 작업이 적극 추진되고 있다 본 논문에서는 안전한 원격의료 서비스 제공을 위해 바이오인식 기술의 융합 필요성과 기술 및 서비스 개발 사례를 분석하고, 원격의료 서비스 활성화를 위해 선결되어야 할 주요 과제를 모색하고자 한다.

The increased life expectancy of human due to the advance of medical techniques has led to many social problems such as rapidly aging populations, increased medical expenses and a lack of medical specialists. Thus, studies on improving the quality of life with the least amount of expense have been going on by incorporating advanced technologies, especially for Personal Health Devices (PHDs), into the medical service market. However, compatibility and extensibility among manufacturers of PHDs have not been taken into account in most of the researches done on the development of PHDs because most of them have been supported by individual medical organizations. The interoperability among medical organizations can not be guaranteed because each medical organization uses different format of the messages. Therefore, in this paper, an expansion module that can enable commercially-available non-standard PHDs to support the IEEE 11073, and a smart-phone-based manager that can support easy and comprehensive management on receiving and transmitting the collected data from each PHD using IEEE 11073 standard were developed. In addition, a u-health system that can transmit the data collected in the manager using the standard data format HL 7 to medical center for real-time medical service from every medical institutions that support this standard was designed and developed.

IOS/IEEE 11073 PHD 표준들은 u-헬스 측정기기와 u-헬스 게이트웨이간의 통신을 가능하게 하도록 설계되어 있다. 모바일 단말기를 데이터 취합을 위한 중계기로 활용하고 별도의 게이트웨이를 구성하여 헬스케어 의료기기를 연동하고 모니터링을 위한 인터페이스를 제공해 왔으나 스마트폰 애플리케이션 단계에서 IEEE 11073 플랫폼을 포함하여 헬스케어 의료기기를 활용하는 u-헬스케어 서비스를 제공하기에는 많은 제약이 있다. 이에 본 논문에서는 Android 4.0.x OS 스마트폰을 대상으로 Bluetooth HDP을 활용하여 u-헬스케어 시스템에서의 게이트웨이/서버 플랫폼 기능을 포함하는 헬스케어 의료기기의 모니터링 애플리케이션 시스템을 설계하였다.

This study was conducted to identify factors related to the problematic experiences of smartphone use among adolescents according to gender. The subjects of this study were 54,603 male and female adolescents. This study data was analyzed using SPSS 25.0 program. As a result of this study, the relevant factors for the problematic experiences of smartphone use among male students were academic performance, economic level, counselors, fast food consumption frequency, depression, suicidal ideation, suicide plan, happiness, subjective body image, stress, and smartphone usage time. Drinking and smoking were found to be significant related factors only for female students. Therefore, in order to reduce the problematic experience of smartphone use, an intervention considering the influence factors according to gender is required.

최근 IT기술의 발달과 의료 서비스의 증가로 웨어러블 헬스케어에 대한 관심이 높아지고 있다. 기존 원칙 진료 시스템에서는 의사와 환자의 직접적인 대면 없이 진료데이터만으로 환자를 판단함으로 인하여 의료서비스의 질이 저하되는 문제가 있었다. 또한 원격진료만으로는 사용자의 증상을 정확하게 전달 할 수 가 없기 때문에 원격진료에 대한 사용자의 만족도가 낮았다. 이를 위해 본 논문에서는 VoIP 환경에서 화상진료를 지원하는 SIP 기반 스마트폰 헬스케어 시스템을 제안한다.

도서관에 RFID 시스템을 도입함으로써 업무의 효율을 높일 수 있다. R-LIM2는 도서의 위치까지 안내하는 기능을 제공하는 RFID 기반의 진보된 도서관리 시스템이지만 위치 추정과 내비게이션에 다수의 안테나 및 별도의 PDA를 사용함으로써 경제적으로는 비효율적이었다. 이에 본 논문에서는 R-LIM2의 내비게이션 기능을 별도의 기기 없이 사용자가 휴대한 스마트폰으로 가능하게 하고, 기존에 구축되어 있는 무선 네트워크 인프라를 활용하여 위치 추정이 가능하게 함으로써 보다 경제적이고 효과적인 도서위치 검색 시스템을 개발하였다.

This study analyzed the content of use Tendency and addiction according to smartphone use of targeting radiological Technologist working in Gyeongnam area. The tool used as the data for the study is a survey. From April 21 to May 31, 2019, a total of 330 questionnaires were distributed to radiological Technologist working at medical institutions in Gyeongnam, and 300 copies suitable for the study were SPSS/PC Ver 18.0 program for Analysis was performed using. The factors of the study subject's tendency to use smartphone were communication, information, leisure, and convenience. As for the addiction factors, a total of 37 questions were analyzed, including daily living disorder, virtual world orientation, tolerance, and withdrawal. Smartphone-related characteristics were set as monthly average fee, usage time, and SNS usage time, and technical statistics, t-test, ANOVA, correlation and regression analysis were performed. The radiological Technologist tendency to use smartphones was 3.10±.55 points, which was average, and smartphone addiction was 2.34±.62 points, which was lower than the average. It was found that there was a significant correlation between the radiological Technologist Tendency to use smartphone and addiction. The effect of radiological Technologist tendency to use smartphone on addiction it was found to account for 10.8%. Through this study, it can be said that it is important to analyze the addiction factors according to the tendency use smartphone of radiological Technologist and to prepare a desirable plan for smartphone use.

The use of smart phones has had a great impact on the mobile internet business. It shows a lot of growth in the healthcare sector not only commerce, advertising, billing, games, video content, media, amd O2O business. The United States has eased the regulations for healthcare apps smart phone devices in 2015, and China has established a five-year road map to solve shortage of doctors and hospital beds by utilizing mobile devices such as wearable in the same year. The application of wearable devices in the medical field is gradually increasing in Korea too, but there is a security problem as leading challenge. Security incidents in non-ICT sectors such as financial, medical, etc. have increased by using ICT each year. Personal information leakage is also increasing in field likely occurring the potential secondary damages such as financial fraud, illegal promotions, insurance and pharmaceutical companies abuse. In this study, we analyze malwares as the mobile threats, the five risks of mobile smart phone, mobile use cases and the mobile threat countermeasures for healthcare.

스마트 폰이 출시된 이후 애플리케이션 마켓은 점점 커지고 있지만 최근 들어 마켓은 새로운 컨텐츠를 내놓지 못하고, 같은 기능을 가진 채 인터페이스만 바뀌어서 출시되고 있다. 하지만 스마트폰에 내장되어 있는 여러 센서를 이용한다면 간단한 의료기기의 기능을 가진 애플리케이션을 구현할 수 있을 것이다. 이에 본 논문에서는 안드로이드를 기반으로 한 스마트폰에서 내장되어 있는 자이로 센서를 이용하여 척추 측만정도를 자가 측정 할 수 있는 기능을 제공하며, 또한 측정된 수치를 데이터베이스를 활용 저장하여 기간별로 자신의 측만도를 쉽게 알아볼 수 있도록 그래프를 이용한 시각적으로 수치를 알려주도록 애플리케이션을 구성하였다.

APP based on the smart phone is being utilized to various scopes such as medical services in hospitals, financing services at banks and credit card companies, and ubiquitous technologies in companies and homes etc. In this service environment, exposures of smart phones cause loss of assets including leaks of official/private information by outsiders. Though secret keys, pattern recognition technologies, and single image authentication techniques are being applied as protective methods, but they have problems in that accesses are possible by utilizing static key values or images like pictures. Therefore, this study proposes a face authentication technology for protecting smart phones from these dangerous factors and problems. The proposed technology authenticates users by extracting key frames of user's facial images by real time, and also controls accesses to the smart phone. Authentication information is composed of multiple key frames, and the user' access is controlled by distinction algorism of similarity utilizing DC values of image's pixel and luminance.
