Health is a fundamental human right and a sine qua non for happiness of people and for national development. Government has a responsibility for the provision of health services for their people. Recent changes of disease pattern, i.e. decrease of Infectious diseases and increase of chronic and degenerative diseases Including cancer and cardiovascular diseases, together with universal coverage of health insurance and improved living standard have prompted medical care utilization and skyrocketed the national health expenses. The goal of national health policy is improving the quality of life through the betterment of health level. To achieve this goal it is necessary to establish a healthcare system for lifetime, to improve the efficiency of healthcare delivery system, and to strengthen the public health services for disease prevention and health promotion. The current public health service programs are Inefficient due to an inconsistent policy for health service program, lack of health information system, irrational health program planning and evaluation, and Inadequate training of health workers. Local government has a legal responsibility for health service program planning and promoting the competence of health workers. Thus, municipal and provincial health departments should expand their roles and strengthen their function. The strategies for developing public health service programs at local level are ${\circled}1$ stipulating the goals of health policy, ${\circled}2$ promoting the ability for health program planning and evaluation, ${\circled}3$ establishing health information and surveillance system, ${\circled}4$ training of health workers, ${\circled}5$ establishing an institution for health information management and training of health workers, and ${\circled}61$ collaboration with local universities.

Recently, the medical image has been digitized by the development of computer science and digitization of the medical devices. There are needs for database service of the medical image and long term storage because of the construction of PACS(picture archiving and communication system) following DICOM(digital imaging communications in medicine) standards, telemedicine, and et al. However, it also caused some kinds of problems, such as illegal reproduction of medical image, proprietary rights and data authentication. In this paper, we propose the new digital watermarking technique for medical image based on public key encryption algorithm for integrity verification. It prevents illegal forgery that can be caused after transmitting medical image data remotely. The watermark is the value of bit-plane in wavelet transform of the original image for certification method of integrity verification. We proposed the embedding regions are randomly chosen considering ROI, and a digital signature is made using hash function of MD5 which input is a secret key. The experimental results show that the watermark embedded by the proposed algorithm can survive successfully in image processing operations and that the watermark's invisibility is good.

최근 한국사회는 국민소득향상, 생활수준의 개선, 의학기술의 발달 등으로 평균수명이 크게 연장 되어 고령화 사회로 발전되어 가고 있다. 평균수명이 짧았던 시대에는 고령화 문제가 크게 중요시되지 않았으나 수명이 연장됨에 따라 노후에 대한 경제적, 사회적 보호문제 등이 대두되고 있다. 노인들의 기본욕구는 주로 소득 보건 주택 여가 등에 관한 것으로 노후에도 자신의 능력과 적성에 맞는 일자리를 찾아 경제적 안정을 누리며 소득을 유지하고 의료보장으로 건강한 노후를 보낼 수 있으며, 가족관계가 안정이 되고 자기발전을 기하며, 사회참여와 역할을 지속하며, 휴식과 오락을 즐기고 문화를 창출하며 삶의 보람을 찾을 수 있는가 하는 것이 문제이다.(중략)

오늘날 최신 의료기술 및 과학의 발달로 인간의 수명이 연장되는 것에 비해 암 발생률은 세계적으로 증가추세에 있다. 암은 인류의 1/3을 사망하게 하는 주요원인으로 인류공동의 관심사이며 온 세계의 과학자나 의학자들에게 주어진 최대 과제이기도 하다. 암발생률과 사망률을 국가별로 살펴보면 미국의 경우 1년에 약 1백만명 정도가 암에 걸리고 그 중 약 45만명 정도가 암으로 사망하고 있는 것으로 보고되고 있으며 일본은 1981년부터 사망 원인 1위가 암으로 밝혀진 후 연간 약 22만명 정도가 암으로 사망하고 있다. 우리 나라 역시 1988년부터 암이 병인별 사망원인 1위가 된 후 최근 1995년에는 인구 10만명당 1413명이 암으로 사망하고 있는 것으로 나타났다. 암의 발병원인은 여러 가지가 있지만 유전적인 요소와 같은 내적 요인보다는 환경적 요인에 의한 발행이 더 큰 원인이 되고 있으며 환경적 요인 중에서도 매일 반복해서 섭취하는 음식물은 매우 중요한 부분을 차지하고 있다. 따라서 우리의 일상적인 식생활에 좀 더 주의한다면 암의 원인이 될 수 있는 식사를 암을 예방할 수 있는 식사로 바꿀 수 있을 것이다.
