Objectives: The development of internet programs for smoking cessation was motivated to quit smoking in the large group of smokers. This personalized program consisted of tailored message to consider the smokers characteristics, and contain the informations on the outcomes of smoking cessation and the skills to be used in the quit attempts. The purpose of this study was to develop the internet management program and information push-delivery system for smoking cessation to encourage the personal intention to quit smoking. Methods: We conducted in 3 steps as developing push service to encourage intention of smoking cessation, analyzing problems of smoking cessation program through the pilot test and suggesting improvements by implication stages. Results: This program is delivered for 30 days. if the participants do not fail to quit smoking. The contents consisted of 13 stages which were divided on starting period. practical period, maintenance period and success period. And push service afforded the tailored message to participants using their e-mail. According to the evaluation of pilot test, the problems of internet information push-delivery service for smoking cessation were the over-tasks per visiting time, recording style of participants, difficulty of terms and sentences, lack of visual effects, absence of follow-up module and unsuitable link with main homepage. Improvements were divided on 3 stages by implication period. The first stage included the immediate improvements as improving link with homepage, modifying menu of smoking information and upload file of notice part. The second stage included the short term improvements as alleviating condition of withdrawal, coordinating start stage of retrial, modifying errors of information push-delivery service and addition of educational materials. The third stage included the long term improvements as development of follow-up module, cost-effectiveness evaluation, reducing contents quantity, introduction of checking style, compensation of graphics effect and review for SMS utilization. Conclusions: This program contribute to improving smoking cessation rate. Therefore this program should be tested in a community to evaluate the effectiveness. To promote the effectiveness, this program should be developed the contents and the strategies for various targets, and established the follow-up system for ex-smokers.

The rapid aging is increasing as the shortage of medical facilities and the resulting of decline in the quality of public health. In order to ease the burden of rising medical expenses, advanced medical institutions are expanding their remote medical care to lower the cost of services. U-healthcare detects the changes in physical and chemical phenomena occurring in the human body and converts them into electrical signals that can be processed and feeds back to the results through analytical and visualization processes to select only the desired information from the measured signals. The service is provided through a process of providing an alarm to a user. However, traditional biometric methods of attaching sensors directly to the body can be annoying and rejected in daily life. Therefore, there is a need for a method of continuously measuring biometric information without causing inconvenience to daily life. In this paper, we propose an IR-UWB-based non-contact and non-responsive respiratory measurement system that can continuously monitor biological information without any inconveniences to daily life.

국가 보건의료체계(health care system)가 올바르게 기능하기 위해서는 의료체계를 구성하는 각 요소들간의 유기적인 상호 작용이 대단히 중요하다. 정보체계는 이러한 유기적인 상호 작용을 위해 보건의료체계의 각 영역에서 꼭 필요한 시스템이다. 보건의료 서비스를 효율적으로 생산하기 위해서 투입하는 자원의 개발과 배치 체계는 물론 생산된 보건의료 서비스를 소비자가 효과적으로 이용할 수 있도록 하는 서비스 전달체계(delivery system)의 전과정에서 보건의료정보체계는 중요한 인프라가 되고 있다. 정보체계는 궁극적으로 보건의료체계가 지향하는 목적을 달성할 수 있도록 짜여져야 한다. 다시 말해, 의료체계의 각 하부영역에서 의료이용의 접근성(accessibility), 형평성(equity), 서비스의 의과학적 질(scientific technical quality), 포괄성(comprehensiveness) 등 보건의료체계가 추구하는 가치를 정보체계에서도 그대로 담아 낼 수 있어야 한다. 또한 정보체계를 구축하기 위한 요건으로 각 사업 영역별 표준화, 사업 영역간의 상호관계, 공공과 민간의 역할 분담, 정보 관련 시선과 인력, 정보기술 등의 인프라, 각 사업 영역별 정보화에서 담아야 할 정보 내용(contents, DB) 등에 대한 사전 기획이 수립되어야 한다. 그 동안 보건의료분야의 정보화사업은 1996년부터 보건소기관의 행정, 진료, 보건 업무지원을 위한 보건소정보화사업과, 1995년부터 초고속공공응용서비스 사업의 일환으로 추진해 온 전염병, 혈액유통, 장기이식, 외래진료예약, 원격진료, 응급의료, 원격치매진료 시스템 구축사업 등이 있으며, 응급의료, 혈액관리, 장기이식, 전염병정보, 외래진료예약시스템을 통합한 보건의료정보통합서비스시스템(1998년) 구축사업 등이 있었다. 이러한 사업들에 대해 현재 평가되고 있는 문제점들로는 정보화 사업에 대한 전략과 비젼이 부재한 상태에서 지나치게 정보기술 중심으로 추진되다 보니 보건의료 정보의 공유나 활용이 전혀 이루어지지 않거나 매우 제한적이었고, 시범사업의 경우는 초기 사업을 추진하기 위한 주체가 명확하지 않았고, 관련 인력의 훈련과 양성이 안 되었으며, 사업 확대를 위한 법적 기반의 취약, 정보화 사업이 부실한 데 대한 평가 기준과 대안 제시 등이 매우 취약한 것이 문제점으로 나타났다. 특히, 정보 내용과 DB 구축을 위한 표준화 등에 대한 사전 설계 부재는 개발된 정보시스템의 운영을 결정적으로 어렵게 만든 요인이 되고 있다. 전반적으로 기존의 정보화사업은 사업 추진을 위해서 꼭 필요한 비젼 수립, 비젼에 따른 목표 설정, 전략 개발, 관리체계 구축, 운영방안 수립 등 단계적인 정보화 계획이 부재한 것으로 평가되고 있어 보건의료정보체계 구축을 위한 종합 비젼 기획(ISP)이 시급한 실정이다.

A total of 35 hospitals throughout Korea were surveyed for the assessment of the educational function of dietitians. The current situation and the depth of practices were diagnosed in such areas as: 1. The continuing education for the hospital dietitians 2. The characteristics of patient consultation performed by the hospital dietitians 3. Systems and methods of patient instruction practiced by the dietitians, and 4. Prospectives in establishing the nutrition education center for the in-and out-patients. The major findings are: 1. Approximately half of the hospital dietitians feel positive about the practicality of their college education for the job. Extremely small number of them are on any kind of continuing education program 2) The monthly average of only 20 patients at one hospital receive diet consultation or nutrition education service from dietitians. The 50% of the consultation cases is taken up by the patients with diabetes and various circulartory diseases followed by the tube feedings, liver and renal diseases with less frequencies 3) Not even a single hospital has an office for the diet consultation and nutrition education for the in-or out-patients. Very few hospital dietetics have educational aids and/or any feedback system to evaluate the effect of the consultation. Charting is not practiced by most dietitians leaving no record of their contributions to the patient care. 4) Although the necessity of the nutrition education center in the hospital is strong1y recognized among dietitians the progress has been blocked by such obstacles as the poor system in the hospital administration in general, short in funds, lack of preparation in the dietetics and the lack of recognition both by the hospital administration and by the dietitian themselves.

The introduction of genetically modified crops has raised concerns regarding safety issues over the insertion of foreign genes into plant genomes using recombinant DNA technology. Since 1991 in Japan, 29 foods and 6 food additives have been evaluated, based on the "Guideline for Safety Assessment", before these foods were marketed. The MHW, however, decided that safety assessment of such foods and food additives should be legally imposed. because soon such foods and food additives are expected to circulate globally and a new system for assessing safety of such foods and food additives at a pre-market stage is necessary, in order to avoid the distribution of any genetically modified foods that have had no safety assessment. The MHW published relevant announcements to amend existing regulations on 1 May 2000. "Standards for safety assessment of seed plant" is established based on a concept of substantial equivalence, and applicable to the products which are regarded as equivalent to the existing products used as foods and food additives. The characterization of the food products entails consideration of the molecular characterization. phenotypic and compositional characteristics, key nutrients and toxicants, and toxicity and allergenicity of the introduced proteins, and if there are indications of unintended effects of the modification, whether further safety testing (animal studies etc.) is needed should be considered. Safety and wholesomeness studies with whole foods should be care fully designed in order to avoid nutritional imbalances causing artifacts and uninterpretable results as was the case of Dr. Pusztaiis report. A case study of genetically modified soybeans (glyphosate-tolerant soybeans) on the immune system of rats and mice is shown. Chemical compositions were also compared with those of the non-GM soybeans. The studies failed to detect any differences in immuno-toxic activity.muno-toxic activity.

Background: The purpose of this study was to ascertain the effects of core program exercise on balance in patients with chronic low back pain. Thirty-four subjects participated in this study, these subjects were assigned into two groups, a control group(n=17) and an experimental group(n=17). Methods: The subjects in the control group were received a conservative physical therapy and in the experimental group carried out the core program exercise for 30 minutes per day, three times a week during 6 weeks. In order to evaluate the progresses of balance ability, corresponding variables were measured at two times, pre and 6th week. The balance ability was assessed using GOOD BALANCE system. The collected data were analyzed by using the paired t-test and ANCOVA. In all statistical analyses, significance level, ${\alpha}$ was set by 0.05. Results: The results of this study were as follows: 1) In the position of left standing eye closed, there were significant difference of Y in the control group and X, Y, V in the experimental group. 2) In the position of right standing eye closed, there were significant difference of Y in the control group and X, Y, V in the experimental group. 3) In the position of dynamic balance 1, there were significant difference APV in experimental groups. 4) In the position of dynamic balance 2, there were significant difference MLV in experimental groups. 5) There were significances between the two group of X, V in static balance and APV in dynamic balance. Conclusion: The above results indicated that a core program exercise improved balance abilities in patients with chronic low back. The further studies should be focused at development of various modified forms of the core program exercise in keeping up the improvement effect of this exercise.

The purpose of study is to understand human-technology integration mechanism by using the study model that takes the core concept and motivation assumptions of technology acceptance model(TAM) into account. This study identifies three motivation mechanisms in adopting or using computer mediated communication(CMC) tool for work. The mechanism comprises with extrinsic, extrinsic motivation, and subjective norm pressure. One hospital with 430 beds and 367 human power was identified and we administered the questionnaire during their work hours. There is 32.4% response rate. The fitting index of the study model surpass the acceptable level, GFI = .980 for none-users, GFI =.986 for users, NNFI = .973 for none-users, and NNFI = .989 for users. In the case of none-users, perceived ease of use determines perceived usefulness that explains behavioral intention to use. As a result, adotpers' usage motivation is based on extrinsic motivation that does not consider their affective factor, attitude, in use of CMC. Users considers their attitudes as the mediating factor of all behavioral beliefs for using CMC continually. Thus, users are likely to depend their adoption behaviors on their affective factor. Moreover, users' behavioral intention is subject to pressures of use from other persons who are important to them, such as supervisor, director, or boss. Achieving human-technology integration in a hospital may cause cost saving and work efficiency. However, the success of information system should base on a profound understanding of employees' adoption behaviors in rejecting, adopting, using, continually using of IT, and organization culture in using IT.
