Purpose: The purpose of this study was to identify a model based on f the learning objectives in adult health nursing curriculums. The model can be eventually reflected in Korean National Nurse's Licensing Examination (KNNLE). Methods: The model was developed through a series of practical analysis by the task force team from June to October, 2011. The research team conducted the data synthesis and analysis from the learning objectives of adult health nursing drawn from selected national and international universities, from the adult health nursing areas in KNNLE, and from the current disease prevalence from clinical data in the representative university hospitals in Korea. Results: The current disease prevalence and mortality rates are on the increase especially for malignant neoplasm, heart diseases, suicide and diabetes. The items on the KNNLE of adult nursing are categorized by body systems into digestive system (15%), introduction (13.8%), respiratory system (11.3%), and cardiac system (11.3%). While the current system-based learning objectives covers extensive areas of adult health nursing, the core items are required to be selected based on core competences and core learning objectives to restructure the items of KNNLE. The first revised model is to consolidate and restructure the items microscopically in the subjects of adult health nursing by system. The second proposed model from macroscopic perspective is to build a comprehensive scheme of nursing curriculum by encompassing 8 subjects under current KNNLE and adjust the number of items accordingly. Conclusion: The items of KNNLE need to be gradually redesigned by considering the intervention need at clinical practice and the modified learning objectives of adult health nursing. Based on the job analysis on core competences for newly employed nurses performed by the Korean Accreditation Board of Nursing, it is necessary to establish the core learning objectives of adult health nursing and set up standards for core items in KNNLE.

Objectives: To develop the smart sensor to protect worker's health from chemical exposure by adopting ICT (Information and Communications Technology) technologies. Methods: To develope real-time chemical exposure monitoring system, IoT (Internet of Things) sensor technology and regulations were reviewed. We developed and produced smart sensor. A smart sensor is a system consisting of a sensor unit, a communication unit, and a platform. To verify the performance of smart sensors, each sensor has been certified by the Korea Laboratory Accreditation Scheme (KOLAS). Results: Chemicals (TVOC; Total Volatile Organic Compounds, Cl₂: Chlorine, HF: Hydrogen fluoride and HCN: Hydrogen cyanide) were selected according to a priority logic (KOSHA Alert, acute poisoning statistics, literature review). Notifications were set according to OEL (occupational exposure limit). Sensors were selected based on OEL and the capabilities of the sensors. Communication is designed to use LTE (Long Term Evolution) and Wi-Fi at the same time for convenience. Electronic platform were applied to build this monitoring system. Conclusions: Real-time monitoring system for OEL of hazardous chemicals in workplace was developed. Smart sensor can detect chemicals to complement monitoring of traditional workplace environmental monitoring such as short term and peak exposure. Further research is needed to expand the scope of application, improve reliability, and systematically application.

기후변화 연구 및 이산화탄소($CO_2$) 지중저장 분야 등에서 $CO_2$ 가스의 탄소안정동위원소비(${\delta}^{13}C_{CO2}$)는 주요한 인자로서 인식되고 있다. ${\delta}^{13}C$는 주로 안정동위원소질량분석기(Isotope Ratio Mass Spectrometry: IRMS)로 분석하지만, 최근 분석비용 및 현장적용성의 문제로 레이저흡광분석기(Laser Absorption Spectrometry: LAS)의 사용이 확대되고 있다. 본 연구는 LAS를 이용한 ${\delta}^{13}C_{CO2}$ 분석 시 분석적합성을 판단하는데 필요한 표준가스의 실질적 확보 방안과 주의사항을 제시하는 것을 목표로 하였다. 실험실 표준가스는 분석할 농도범위로 $CO_2$ 가스를 조제한 후, 한국인정기구 인증시험기관에서 $CO_2$ 농도를 측정한 후에 IRMS로 ${\delta}^{13}C_{CO2}$를 측정하여 사용하였다. 장시간 측정 시, 농도가 상대표준편차 1.0% 이하로 변이하면 ${\delta}^{13}C$는 최대 ${\pm}10$‰까지 변동할 수 있으므로, 표준가스를 주기적으로 측정하여 분석 적합성을 판단하고 필요 시 보정을 하여야 한다. ${\delta}^{13}C_{CO2}$는 $CO_2$ 농도에 의존성을 나타내므로, 분석하고자 하는 영역의 최소 및 최대 농도를 갖는 표준가스의 혼합실험을 통해 보정식을 산출하였으며, 보정 후 ${\delta}^{13}C_{CO2}$는 IRMS 측정값에서 ${\pm}0.52$‰ 이내의 편차를 나타내었다.
