최근 IT 기술이 발전함에 따라 실시간 심전도 모니터링이 가능해 졌으며, 이는 의료정보교환을 위한 HL7 표준의 전도 유망한 응용 중 하나로 인식되고 있다. 하지만 HL7 메시지 내 데이터 중복으로 인한 메시지의 크기 및 생성시간의 증가로 인해 HL7 표준을 실시간 심전도 모니터링에 바로 적용하기에는 무리가 있다. 이에 본 논문에서는 실시간 심전도 모니터링에 적합한 HL7 메시지의 간소화 전략을 제안한다. 다양한 형식의 심전도 데이터를 Feature Scaling을 거쳐 정형화된 포맷으로 조정하고 HL7 규약에 순응하는 메시지를 생성한다. 또한 HL7 ORU 메시지 내의 중복되는 OBX 필드를 제거하기 위해 De-Duplication 알고리즘을 수행한다. 이를 통해 기존의 HL7 표준 적용 대비 메시지의 생성시간은 최대 51%, 크기는 최대 1/8로 줄일 수 있음을 실험적으로 확인하였다.

정보통신과 산업기술의 급속한 발전으로 인간과 모든 프로그램 그리고 사물들이 인터넷을 통해 연결되는 초연결사회(hyper-connected society)가 구현되고 있다. 초연결사회를 구현하기 위한 정보의 수집은 사물과 사물 그리고 사물과 인간을 연결하는 사물인터넷(IoT: Internet of Thing)이 그 역할을 담당하고 있다. (MQTT: Message Queuing Telemetry Transport)는 이런 사물인터넷의 제약된 통신환경에 최적화되어 개발된 푸시 기술(push technology) 기반의 경량 메시지 전송 프로토콜이다. 초연결사회를 지향하면서 IoT가 담고 있는 정보는 센서의 환경정보에서 이제는 사람의 질병과 건강관리까지 담당하는 광범위한 정보가 되었다. 이런 MQTT에 대한 보안 문제는 환경정보 유출뿐만 아니라 개인의 정보 침해에까지 이르게 되었다. 우리는 이런 MQTT의 보안의 문제점을 해결하기 위해 혼돈계의 초기치 민감성, 유사 난수성을 무결성과 기밀성에 적용하여 새로운 보안 MQTT통신방법을 설계하였다. 우리가 설계한 혼돈계를 이용한 암호화 방법은 구조가 간단하고 계산량이 적기 때문에 IoT와 같은 제한된 통신환경에 적합한 통신방법이라고 생각된다.

Purpose: This study examined the correlation between satisfaction with major, academic self-efficacy, and academic persistence with the general characteristics of students in a health-related field, to determine factors that affect academic persistence. Methods: The study was conducted on third- and fourth-grade health-field students at Daejion. The questionnaire consisted of a self-report, and a URL was sent by text message to students who agreed to participate after reading the purpose and necessity of the study. Results: Major satisfaction was 4.23 on average, academic self-efficacy was 4.15, and academic continuity was 4.25. Grade and school life satisfaction were the factors correlated with a significant difference in academic persistence. Significant positive correlations were seen between satisfaction with major (r=.637, p<.001) and academic self-efficacy (r=.563, p<.001); higher major satisfaction and academic self-efficacy led to higher academic persistence. Conclusion: A more systematic management approach needs to be conducted by developing active learning participation and applying customized counseling management and support programs by grade to improve the academic self-efficacy and academic persistence of students in health-related fields.

Introduction: Mobile learning enables users to interact with educational resources while in variable locations. Medical students in residency positions need to assimilate considerable knowledge besides their practical training and we therefore aimed to evaluate the impact of using short message service via cell phone as a learning tool in residents of Obstetrics and Gynecology in our hospital. Methods: We sent short messages including data about breast cancer to the cell phones of 25 residents of gynecology and obstetrics and asked them to study a well-designed booklet containing another set of information about the disease in the same period. The rate of learning derived from the two methods was compared by pre- and post-tests and self-satisfaction assessed by a relevant questionnaire at the end of the program. Results: The mobile learning method had a significantly better effect on learning and created more interest in the subject. Conclusion: Learning via receiving SMS can be an effective and appealing method of knowledge acquisition in higher levels of education.

Purpose: This study was to identify the persuasive effects of exercise promotion advertisements for obesity prevention according to the source types( ordinary people, experts, celebrity endorsers) and advertising message types(slices of life, testimonials). Method: Gender, height, body weight, BMI, attitude toward obesity(Aob) and exercise(Aex), and intention to exercise(Iex) were collected from 626 elementary school students in a pretest. After 2 months, six advertisements type attached to a questionnaire were provided for 20 minutes and then Aob, Aex, lex, source credibility and attitude toward advertisements(Aad) were collected in posttest. Result: 1) In posttest the lex of 6 the groups increased significantly compared with that of the pretest, 2) Source credibility of the Ordinary+Testimonial group was lower than the Celebrity+Testimonial, Celebrity+Slice of life, Ordinary+Slice of life, and Expert+Testimonial groups, Aad of the Celebrity+Testimonial group was higher than the Ordinary+ Testimonial group. 3) The Main effect and interaction effect of source types and advertising message types were significant in source credibility and Aad, Conclusion: Persuasive effects of exercise promotion advertisements in elementary school students was found to be the most effective in Celebrity+Testimonial. This study suggests that selection of health education advertisements according to demographic characteristics is important to promote persuasive effects.

Internet websites are excellent resources for younger people to gain information related to breastfeeding. So in this study, we evaluated the breastfeeding knowledge of university students, as well as the currently available website information on breastfeeding. Among the criteria, the six most important evaluation categories for the breastfeeding information on websites were selected and identified. The study participants completed the modified Williams and Hammer's tool, in order to evaluate their breastfeeding knowledge. An additional tool took into consideration the website breastfeeding information criteria, to evaluate the Korean websites. This 34 item tool was categorized into milk supply, comfort during breastfeeding, health of the baby and mother, social support, presentation of message, and products or financial motivation. Thirty-seven websites related to breastfeeding were evaluated, and the results were then discussed by nursing students. The students in this study were not knowledgeable on breastfeeding management with regard to the expression and storage of breast milk, the prevention and care of sore nipples, or use of breastfeeding aids. The breastfeeding information found on the Korean websites received positive evaluations for milk supply, comfort during breastfeeding, and health of the baby and mother. However, the educational content on social support, the message presentation, and the product areas on websites were rare or required additional information from breastfeeding specialists. In conclusion, based on our empirical survey, we need to design websites and evaluation tools for accurate website information regarding the social and economic benefits of breastfeeding, so that Korean women are better motivated to breastfeed by the information they obtain through the Internet.

건강정보의 교환, 통합, 공유, 검색의 표준을 개발하는 Health Level Seven(HL7)에서 발표된 표준들은 글로벌한 의료정보 서비스에 성공적으로 사용되고 있다. 그러나 V2.x Message와 V3 Clinical Document Architecture(CDA)는 습득하고 개발하는 데 많은 시간이 소요되는 문제점이 있다. 개선된 Fast Healthcare Interoperability Resources(FHIR)를 사용함으로써 이러한 문제점을 해결할 수 있는 방법인지 모색한다. 개인건강기록이 사회적인 관심을 끌고 있고, 스마트폰 보급률이 급격히 증가하는 점을 반영하여 스마트폰으로 접속 가능한 개인건강기록 프로파일링 시스템을 개발한다. Furore에서 개발한 FHIR Profile editor tools을 통해 profile의 생성, 변경의 개선점을 찾아본다. 이와 같은 시스템을 구축하기 위해서 Electronic Medical Record(EMR) 시스템과 Personal Healthcare Record(PHR) 시스템 간의 정보교류를 FHIR Open API로 구성한다. PHR 프로파일링 시스템에서는 이들 트랜잭션을 RESTful 서비스로 제공한다. 본 연구에서는 FHIR를 통해 PHR 프로파일링 시스템 개발의 효율성을 검증한다.
