Objectives : To analyze medical expenses by cancer site and survival time among cancer patients in their last year of life. Method : The study subjects were 45,394 people that had died of cancers in 2002, were registered by the Korea Central Cancer Registry and received National Health Insurance benefit in the last year (360 days) of life. Personal identification data, general characteristics, dates of death and cancer incidence, and site of cancer were collected from the National Statistical Office and the Korea Central Cancer Registry, and merged with the data of the individual medical expenses of the Health Insurance Review Agency. Results : Average monthly cost curves were U-shaped with high costs near the time of diagnosis and death, and lower costs in between. Medical expenses in the last year of life were around 30.3, 16.7, 13.0, and 12.1 million won among leukemia, lymphoma, ovarian cancer, and breast cancer patients, respectively. Digestive organ cancers including stomach, esophagus, liver, pancreas, and colorectal cancers had relatively low medical expenses. Medical expenses in the last year of life were inverse U-shaped with high expenses near one year of survival. Average monthly cost in the 12 months before death among the patients who had survived $10{\sim}15$ years were more than two-fold greater than the cost before diagnosis among those who had survived for less than one year. Conclusions : Leukemia was the most expensive cancer. It is possible that once diagnosed as cancer, medical expenses do not return to the level before diagnosis. Further research will be needed to understand the magnitude and change of the medical expenses among cancer patients with long term follow up data.

무선 센서 네트워크는 언제, 어디에서든, 때와 장소를 가리지 않고 사용자가 원하는 서비스를 제공해주는 시스템이다. 특히, 바이오 센서를 이용한 의료센서네트워크는 생명공학, 의료공학 분야에서 활발하게 활용이 되고 있다. 의료센서네트워크에서는 사용자가 시간적이나 공간적 제약을 받지 않고 집에서 건강을 모니터링 할 수 있는 환경이다. U-healthcare환경에서 긴급 상황이 발생 했을 때 빠르게 환자를 도와줄 수 있으며, 병원에서도 손쉽게 환자를 관리 할 수 있다는 장점을 갖는다. 이 환경에서는 개인의 건강과 생명에 직결된 데이터가 송수신되므로 개인의 프라이버시 보장과 데이터의 보안이 가장 중요한 요소이다. 본 논문에서는 휴대폰을 이용한 사용자 인증 방안과 데이터의 종류에 따라 긴급모드와 일반모드의 구분을 두어 안전하면서도 빠르게 데이터를 전송하는 방안을 제안하였다.

최근 병원정보 시스템은 의료서비스의 질과 효율성을 제고하기 위해 스마트폰 및 태블릿 PC를 활용한 스마트 진료서비스가 대형병원을 중심으로 도입되고 있으며 개인의 진료정보를 PC, 스마트폰 등을 통해 관리하는 개인건강기록(PHR) 서비스에 대한 관심 및 기술개발이 활발히 진행 중에 있다. 이러한 차세대 병원정보 시스템을 구축하기 위해서는 상이한 병원정보 시스템 간의 데이터 연동과 다양한 사용자 기기 간의 UX 일관성이 보장되어야 한다. 따라서 본 논문에서는 이러한 멀티플랫폼 환경 하에서 의료정보를 통합하여 연동할 수 있는 게이트웨이 시스템을 설계하기 위해 개인의 진료정보 표준과 성능 향상을 위한 연구를 수행하였다. 본 연구를 통해 게이트웨이 시스템의 핵심 기능인 데이터 간의 매핑 방법에 있어서 CCR 표준을 적용하고 다중 테이블 기반 매핑 방법을 사용하여 시스템 설계를 하였다. 이에 대한 성능 평가를 위해 실험을 한 결과 응답속도가 약 20% 향상된 결과를 얻을 수 있었다.

The purpose of this study is to examine the factors that influence school life satisfaction based on personal variables, self-esteem, interpersonal relationships, and perception of the educational environment at a medical school in Korea. The data were collected from 228 medical students who agreed to participate in the study at a medical school. The Dundee Ready Medical Environment Measure (DREEM) and the self-esteem scale by Rosenberg were used. Questions measuring satisfaction of medical school life and interpersonal relationships (with professors, with senior/junior students, and with friends) were asked using a 5 point Likert scale. The data were analyzed by t-test, analysis of variance, and multiple regression analysis. The satisfaction of medical school life of male students was significantly higher than female students and increased with years of schooling. In DREEM, the students' perception of teachers decreased by school years. The relationship with senior and junior students of third year students was higher than other school years. The result of the regression analysis to determine the variables that affect satisfaction of medical school life showed that interpersonal relationships with senior and junior students, the students' social self-perception, and the students' perception of learning were significant. The results of this study will help medical schools in their plans to improve the level of satisfaction for the happiness and successful academic achievements of their students.

The first survey were conducted from March 20 to April 2. The second survey were conducted from August 8 to September 5 on same group. The data were analyzed by pecentage, mean, t-test using SAS program. The result of this study were as follows : 1. The average item score for the health promoting was 2.35 at freshman. 2. The average item score for the health promoting was 2.59 after one year on same group. In the subcategories, the highest degree of performance was personal relationship support, self-actualization, stress management, nutrition and health responsibility and the lowest degree was sports. 3. Hypothesis that the EMT student who get health education will have a higher degree of health promoting behavior than the freshman EMT student was accepted.

요즈음, 원격 처방전 및 원격 진료가 시범적으로 운영되고 있다. 그러나 대부분의 원격지 병원에서 환자 생체 데이터를 암호화 하지 않고 전송하는 경우, 해커가 환자 처방전 데이터를 해킹해서 처방전 약물을 바꾸면 환자는 심각한 장애를 받을 수 있다. 따라서, 본 논문에서는, 이러한 문제점을 해결하기 위해 원격 처방전과 의료 정보시스템에 환자의 비밀번호, 개인 식별 정보, 바이오 정보 등을 암호화하는 알고리즘과 안전한 보안 구현 방안이 제시되었다.

고령화 사회로 인한 만성질환자의 증가로 그들의 질병 예방과 관리가 시급하다. 이러한 문제를 해결하기 위한 생체인증 방법과 원격의료시스템들이 소개되고 있으나 의료정보와 개인인증의 보안성 문제를 해결하는데에는 어려움이 있다. 스마트 헬스케어는 대상자의 개인 의료정보를 포함하고 있으므로 무엇보다 개인정보의 보안이 중요한 분야이다. 따라서 본 논문에서는 프라이빗 블록체인 환경에서 손목 밴드 형태의 스마트 웨어러블 디바이스 ECG와 얼굴 개인인증을 활용한 원격의료시스템을 제안하고자 한다. 이 시스템에서는 다양한 의료인과 전 지역 만성질환자를 대상으로 하였으며, 데이터의 무결성과 투명성을 높일 수 있는 프라이빗 블록체인을, 위변조가 어렵고 개인식별성이 높은 ECG와 얼굴인증을 활용하여 보안성과 신뢰성이 높일 수 있는 시스템을 구성하였다. 이를 통해 재가 만성질환자의 질병 예방과 건강관리에 힘써 만성질환 관리의 효율성을 높이는데 기여하고자 한다.

Purpose: The aims of this study were to describe the levels of personal coping resources, perceived organizational supports, and job stress, and to examine factors that affect job stress in hospital-based home care nurse practitioners. Methods: A cross-sectional survey was conducted. Data were collected from 170 subjects with a structured questionnaire from April to July, 2016 and analyzed using descriptive statistics, t-tests, One-way ANOVA, Pearson's correlation, and multiple regressions. Results: The means for personal coping resources, perceived organizational supports, and job stress were $3.7{\pm}0.43$, $3.4{\pm}0.55$, and $3.4{\pm}0.55$ out of 5, respectively. Personal coping resources and perceived organizational supports were significantly correlated. However, both had no associations with job stress. In the multiple regression analysis, the experiences of home care nursing and hospital location were found to be predictors of job stress. Both personal coping resources and perceived organizational supports were not statistically significant predictors of job stress. Conclusions: It is necessary to carry out organization-based educational programs and support systems aimed at enhancing personal abilities to cope with stress at work. Additionally, further studies are needed to identify other hospital-related characteristics that can lead to job stress in home care nurse practitioners.

Background: Interest in digital medical information has increased because it allows doctors to easily access a patient's medical records and provide appropriate medical care. Blockchain technology ensures data safety, reliability, integrity, and transparency by distributing medical data to all users over a peer-to-peer network. This study attempted to assess pediatricians' thoughts and attitudes toward introducing blockchain technology into the medical field. Methods: This study used a questionnaire survey to examine the thoughts and attitudes of 30- to 60-year-old pediatricians regarding the introduction of blockchain technology into the medical field. Responses to each item were recorded on a scale ranging from 1 (never agree) to 7 (completely agree). Results: The scores for the intentions and expectations of using blockchain technology were 4.0 to 4.6. Pediatricians from tertiary hospitals responded more positively (4.5-4.9) to the idea of using blockchain technology for hospital work relative to the general population (4.3-4.7). However, pediatricians working in primary and secondary hospitals had a slightly negative view of the application of blockchain technology to hospital work (p=0.018). Conclusion: When introducing the medical records of related pediatric and adolescent patients using blockchain technology in the future, it would be better to conduct a pilot project that prioritizes pediatricians in tertiary hospitals. The cost, policy, and market participants' perceptions are essential factors to consider when introducing technology in the medical field.
