Purpose: The purpose of this study was to investigate the influence of perceptions of death, end-of-life (EOL) care stress, and emotional intelligence on attitudes toward EOL care among nurses in the neonatal intensive care unit (NICU). Methods: The participants were 111 nurses working in a NICU who had experienced EOL care at least once. Data were analyzed using the t-test, Pearson correlation coefficient, and stepwise multiple regression analysis in SPSS for Windows. Results: The mean score for perceptions of death was 3.16 out of 5, the mean score for EOL care stress was 3.61 out of 5, the mean emotional intelligence score was 4.66 out of 7, and the average score for EOL care attitudes was 2.77 out of 4. The factors affecting attitudes towards EOL care were academic degree, anxiety regarding death, negativity towards death, experiences of patient death, and emotional intelligence. The explanatory power of these variables for attitudes towards EOL care was 24.7%. Conclusion: The results of this study are expected to serve as a basic reference for the development of nursing education programs and EOL care protocols to improve attitudes toward EOL care among NICU nurses.

유비쿼터스 컴퓨팅 환경에서는 사용자의 다양한 요구에 부응하기 위하여 지식을 활용한 서비스의 필요성이 증가하고 있다. 온톨로지는 이같은 분산 컴퓨팅 오브젝트들 사이에서 지식 공유를 위한 표현 방법으로 많이 사용되고 있다. 이러한 온톨로지를 표현하고 처리하기 위해 본 연구에서는 Description Logic 기반 지식 표현 언어인 EOL을 바탕으로 지식을 활용하기 위한 추론 엔진을 구현하였다. EOL 은 간결하고 직관적인 문법으로 비전문가도 EOL을 사용해 지식을 쉽게 표현 및 활용할 수 있다. 본 논문에서는 이러한 EOL 로 표현된 지식을 보다 효율적으로 처리하기 위해 지식의 표현 범위에 따라 각기 다른 추론 알고리즘을 사용하는 추론 엔진을 구현하였다.

Purpose: This study aimed to identify the view of life and death among ICU nurses and to analyze the problems related to end-of-life care in the current ICUs. Methods: A descriptive study design was used. The participants were 975 nurses working in the intensive care units of 16 general hospitals. Using a descriptive survey design, data were collected from August to December in 2016 and were analyzed using descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression analysis. Results: As a result of a correlation analysis of the data, Death perception had a significant positive correlation with EOL of nursing attitudes(r=.100, p=.002), and negative correlation with EOL stress care(r=-.221, p=<.001). The regression model explained for individual characteristics in the model, age(${\beta}=.126$, p<.001) and death perception(${\beta}=.182$, p<.001), Satisfaction of the EOL care(${\beta}=.173$, p<.001), Healing training needs on the EOL(${\beta}=-.144$, p<.001) were the most influential factors for EOL stress. Conclusion: Results reveal that ICU nurses have a moderate level of EOL stress, and that individual, age, death perception, Satisfaction of the EOL care, Healing traning needs on the EOL relevant in ICU nurses' EOL stress. Programs or interventions to reduce EOL stress and to should be developed taking into account these multidimensional factors.

We successfully fabricated 4.7-inch organic thin film transistors array with $640{\times}480$ pixels on flexible substrate. All the processes were done by photolithography, spin coating and ink-jet printing. The OTFT-Electrophoretic (EP) pixel structure, based on a top gate OTFT, was fabricated. The mobility, ON/OFF ratio, subthreshold swing and threshold voltage of OTFT on flexible substrate are: 0.01 ^2/V-s, 1.3 V/dec, 10E5 and -3.5 V. After laminated the EP media on OTFT array, a panel of 4.7-inch $640{\times}480$ OTFT-EPD was fabricated. All of process temperature in OTFT-EPD is lower than $150^{\circ}C$. The pixel size in our panel is $150{\mu}m{\times}150{\mu}m$, and the aperture ratio is 50 %. The OTFT channel length and width is 20 um and 200um, respectively. We also used OTFT to drive EP media successfully. The operation voltages that are used on the gate bias are -30 V during the row data selection and the gate bias are 0 V during the row data hold time. The data voltages that are used on the source bias are -20 V, 0 V, and 20 V during display media operation.

This paper shows a whole noise quality checking system for the new developed 6th speed automatic transmission manufactured in USA. Due to demand for manufacturing of the high NVH quality transmissions in the mass product line, some special checking system called EOL is adapted. This EOL system is using vibration analysis technologies. Through adapting vibration analysis technologies and functions likewise RMS, Crest Factor, Harmonics, Peak, Band, and Order tracking, various noise problems caused by wear, nick, and deformations could be successfully detected and predicted. Therefore, automatic transmissions manufactured in the USA could get high NVH quality.

Fuel temperature coefficient (FTC) of PuO₂+ZrO₂ (ROX) fueled LWR cell is analyzed neutronically with reactor- and weapons-grade plutonium fuels in comparison with a U-free PuO₂+ThO₂ (TOX), and a conventional MOX fuel cells. The FTC value of a ROX fueled LWR is smaller compared to a TOX or a MOX fueled LWRs and becomes extremely positive especially, at EOL. This is because when fuel temperature is increased, thermal neutron spectrum is shifted to harder, which is extreme at EOL in ROX fuel than that in TOX and MOX fuels. Consequently at EOL, ²³⁹Pu and ²⁴¹Pu contributes to positive fuel temperature reactivity (FTR) in ROX fuel, while they have negative contribution in TOX and MOX fuels. The FTC problem of ROX fuel is mitigated by additive ThO₂, UO₂ or Er₂O₃. In ROX-additive fuel, the atomic density of fissile Pu becomes more than additive free ROX fuel especially at EOL, which is the main cause to improve the FTC problem. The density of fissile Pu is more effective to decrease the thermal spectrum shifts with increase the fuel temperature than additive ThO₂, UO₂ or Er₂O₃ in ROX fuel.

생산자 폐기 책임 규제 강화로 인하여, 제조업 영역이 제품 제조(BOL) 뿐만 아니라 사용, 보수(MOL)와 폐기(EOL)까지 확장 수명주기로 확대 되고 있다. 또한 EOL상에서 개별 제품에 대한 제품 복원 관리 시스템 (PRMS: Product Recovery Management System)에 관한 연구가 활발히 진행 되고 있다. 그러나 BOL, MOL과 EOL간의 정보 단절 문제, MOL상의 정보를 저장하고 사용할 수 없었던 문제는 EOL관리의 자동화를 저해한 큰 요인이다. 최근 유비쿼터스 기술의 발달로 개별 제품 추적이 가능해 졌지만, EOC 등의 식별부호(ID)만으로는 PRMS에 필요한 제품 정보를 얻을 수 없다. 본 논문에서는 제품 ID로부터 MOL상의 정보를 연결하고, 국제표준 기반 정보모델을 이용하는 PRMS를 개발한다. 이를 위해: (1) PRMS에 필요한 정보를 국제표준(ISO10303-239 등)을 기반으로 모델링하고, (2) 제품 ID를 통해 MOL상의 정보를 수집하여 제품 복원에 대한 의사결정을 수행할 수 있는 PRMS를 설계하고, (3) 시제품 구현을 통해 제안된 데이터 모델 및 시스템의 유효성을 검증한다.
