RFID/USN은 유비쿼터스 컴퓨팅을 위한 핵심 기술로써 다양한 센서기술과 프로세서 집적기술 그리고 무선 네트워크 기술을 이용해서 실제 물리적 환경 정보를 원격에서 손쉽게 수집하고 모니터링 하는 것이 가능하다. 특히 의료분야는 U-Healthcare와 결합된 보건의료산업과 서비스에서 국제적인 경쟁력을 확보한 수 있을 것으로 기대되고 있다. 하지만 USN은 RFID의 표준 관리 시스템인 EPCglobal 아키텍처와 갚은 표준 프레임워크의 부재로 상호 운영 및 글로벌 센서 네트워크 구현에 문제점이 있다. 따라서 본 논문에서는 USN의 센서 노드를 관리하는 시스템인 SIP 기반의 USN 관리 시스템 (UMS)을 제안한다. UMS는 세션 관리 기능 및 이동성 지원을 제공하는 SIP(Session Initiation Protocol)라는 인터넷 표준 프로토콜에 기반을 두고 있다. UMS 아키텍처는 기존의 SIP 아키텍처에 UUA(USN User Agent)와 UNS(USN Name Server)를 추가함으로써 이동성을 고려한 센서 노도의 위치 및 상태를 관리하게 된다. UUA는 제한된 능력의 센서 노드를 대신해 위치 등록과정을 수행하고 UNS는 센서 노드의 위치 추적을 위해 이름 변환 서비스를 제공한다. 제안하는 관리 시스템은 하나의 통일된 규격이 존재하지 않는 현재의 센서 네트워크를 통합 및 연동을 쉽게 히여 인터넷을 기반한 글로벌한 센서 네트워크 구축을 가능하게 한다. 또한, 인터넷 표준 프로토콜인 SIP를 사용하기 때문에 다른 서비스 및 프로토콜과의 연동이 쉽고 SIP 기반의 기존 자원을 재활용 활 수 있는 장점을 가진다. 본 논문에서는 제안하는 UMS를 기반으로 혈액관리 시스템의 시나리오를 통해 타당성을 검증한다.

The purpose of this study was to evaluate the accuracy of a mobile wireless digital automatic blood pressure monitor for clinical use and mobile health (mHealth). In this study, a manual sphygmomanometer and a digital blood pressure monitor were tested in 100 participants in a repetitive and sequential manner to measure blood pressure. The guidelines for measurement used the Korea Food & Drug Administration protocol, which reflects international standards, such as the American National Standard Institution/Association for the Advancement of Medical Instrumentation SP 10: 1992 and the British Hypertension Society protocol. Measurements were generally consistent across observers according to the measured mean ${\pm}SD$, which ranged in $0.1{\pm}2.6mmHg$ for systolic blood pressure (SBP) and $0.5{\pm}2.2mmHg$ for diastolic blood pressure (DBP). For the device and the observer, the difference in average blood pressure (mean${\pm}$SD) was $2.3{\pm}4.7mmHg$ for SBP and $2.0{\pm}4.2mmHg$ for DBP. The SBP and DBP measured in this study showed accurate measurements that satisfied all criteria, including an average difference that did not exceed 5 mmHg and a standard deviation that did not exceed 8 mmHg. The mobile wireless digital blood pressure monitor has the potential for clinical use and managing one's own health.

Purpose : The information of mental health facilities in Korean law is so unclear that people hardly enable to understand what sort of proper mental health service is prepared for them. Futhermore, there is not enough regulation and standard to classify each type of facilities in the law. Therefore the purpose of this study is to provide data on the basis for classification and facility standards by analysing Korean law and policies. Methods : This study was conducted by a research on law and regulation of mental health facility. Results : The result of this study can be summarized into three points. The first one, current law and policy do not reflect a change in community mental health services paradigm. The second one, the classified facility should be designed to fit the community mental health services. The third one, overall, it requires more detailed guidelines to enhance the quality of mental health services. Besides, the treatment as well as the function of the prevention and rehabilitation are necessary criteria that can also be enhanced. Implications : This study looked at the classification and facility standard of mental health facility by the change in community mental health services paradigm. Forward according to these changes, there is a need for specific guidelines for mental health facility.

Background: The purpose of this study is to construct a job-exposure matrix for lead that accounts for industry and work processes within industries using a nationwide exposure database. Methods: We used the work environment measurement data (WEMD) of lead monitored nationwide from 2015 to 2016. Industrial hygienists standardized the work process codes in the database to 37 standard process and extracted key index words for each process. A total of 37 standardized process codes were allocated to each measurement based on an automated key word search based on the degree of agreement between the measurement information and the standard process index. Summary statistics, including the arithmetic mean, geometric mean, and 95th percentile level (X95), was calculated according to industry, process, and industry process. Using statistical parameters of contrast and precision, we compared the similarity of exposure groups by industry, process, and industry process. Results: The exposure intensity of lead was estimated for 583 exposure groups combined with 128 industry and 35 process. The X95 value of the "casting" process of the "manufacture of basic precious and non-ferrous metals" industry was 53.29 ㎍/m³, exceeding the occupational exposure limit of 50 ㎍/m³. Regardless of the limitation of the minimum number of samples in the exposure group, higher contrast was observed when the exposure groups were by industry process than by industry or process. Conclusion: We evaluated the exposure intensities of lead by combination of industry and process. The results will be helpful in determining more accurate information regarding exposure in lead-related epidemiological studies.

The respiratory medical device is a medical device that delivers optimal oxygen or a certain amount of humidification to a patient by delivering artificial respiration to a patient through a machine when the patient has lost the ability to breathe spontaneously. These include respirators for use in chronic obstructive pulmonary disease and anesthesia or emergency situations, and positive airway pressure devices for treating sleep apnea, and as the population of COPD (chronic obstructive pulmonary disease) and elderly people worldwide surge, the market for the respiratory medical devices it is getting bigger. As the demand for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, the boundaries between the items are blurred due to the purpose, intended use, and method of use overlapping similar items in a respiratory medical device. In addition, for both airway pressure devices, there is a problem that the ventilator standard is applied because the reference standard has not been established. Therefore, in this study, we propose clear classification criteria for the respiratory medical devices according to the purpose, intended use, and method of use and provide safety and performance evaluation guidelines for those items to help quality control of the medical devices. And to contribute to the rapid regulating and improvement of public health. This study investigated the safety and performance test methods through the principles of the respiratory medical device, national and international standards, domestic and international licensing status, and related literature surveys. The results of this study are derived from the safety and performance test items in the individual ventilator(ISO 80601-2-72), the International Standard for positive airway pressure device (ISO 80601-2-70), The safety and performance of humidifiers (ISO 80601-2-74) and the safety evaluation items related to home healthcare environment (IEC 60601-1-11), In addition, after reviewing the guidelines drawn up through expert consultation bodies including manufacturers and importers, certified test inspection institutions, academia, etc., the final guidelines were established through revision and supplementation. Therefore, in this study, we propose guidelines for evaluating the safety and performance of the respiratory medical device in accordance with growing technology development.
