김채원,박미현,Kim, Chaewon,Park, Mihyun 한국가정간호학회 2021 가정간호학회지 Vol.28 No.3
Purpose: This study investigated the degree of, and factors influencing the spiritual care among home healthcare nurses. Methods: The subjects were 168 advanced practice nurses working in 94 hospital-based facilities for home health care located in Seoul, Gyeonggi-do, and Incheon Metropolitan City. Data were collected from January 14, 2019, to March 7, 2019, using structured questionnaires on spiritual care and related variables based on the literature. Data were analyzed by t-test, one-way ANOVA, Pearson correlation, and multiple regression analysis (stepwise) using SPSS Version 23.0 program. Results: The results showed that the degree of spiritual care of home health care nurses was 3.44 points out of a possible 5 points. Factors affecting nurses' spiritual care were spiritual well-being(𝛽=.36, p<.001), recognition of spiritual care as the nature of nursing(𝛽=.17, p=.016) and role of nurses(𝛽=.22 p=.002), regular-based education for spiritual care(𝛽=.23, p<.001), patients' discomfort with spiritual discussion(𝛽=-.18, p=.001), and nurses' experience in home health care area(𝛽=.14, p=.010), which explained 57.2% of the observed variation in spiritual care. Conclusion: This study suggests the need to develop regular-based education programs for facilitating spiritual care and strengthening home health care nurses' spiritual well-being and their positive perceptions toward spiritual care.

김채원,Kim, Chai-Won 한국자동차공학회 2007 한국 자동차공학회논문집 Vol.15 No.2
This paper studied performance characteristics of hybrid automotive to replace existing fossil fuel vehicles. Specially, about power split type HEV that is T-HEV's drive system when a vehicle drives at steady speed, monitored both output of each engine, motor and generator and battery SOC (state of charge) and analyzed performance characteristic of power transmission system and electricity power parts. This study shows those that acquired and analyzed information from signals between HCU and each controller of actual T- vehicle. From this study, it is confirmed that each conditions of EV and HEV drive can be a improvement with respect to the fuel efficiency of vehicles.

A new series of 3-allylseleno-6-alkylthiopyridazines6a–6g was synthesized by two synthetic routesfrom 3,6-dichloropyridazine to develop new anticanceragents. These new compounds showed antiproliferativeactivities against breast cancer (MCF-7) cells in CCK-8assays, and could be promising candidates for chemotherapyof carcinomas. Compound 6e (3-allylseleno-6-pentylthiopyridazine)showed higher potency than 5FU forinhibiting the growth of these cell lines. This suggests thepotential anticancer activity of compound 6e.
자동차에서 PDM 도입을 위한 Process 구축방법론
김채원,Kim, Chai Won 한국시스템엔지니어링학회 2006 시스템엔지니어링학술지 Vol.2 No.2
It was difficult that each enterprise clearly defines PDM in domestic vehicle manufacturing industry and decides investment for the successful foundation in the mid-90s. Also, it was true that most investments to success repeat a process of trial and error even if they decide and propel. Now, PDM is not a luxurious system. Because the company is operated well even if it manages business manually, the company may not be interested in PDM introduction. Problem is business efficiency and product competitiveness. Now, we must consider that introduction and drive of PDM became necessary as instrumentation for Re-Engineering of business process concerning innovative dimension restructuring that is not reorganization, development and improvement of business for enterprise's survival. This indicates that now is when level of infra construction for an IT technology dominates competitiveness of business management. Enterprise can expect effects of PDM by implementation that manages Intellectual Properties through administration of knowledge and information finally.

본 논문에서는 잡음 제거 회로를 이용하여 공급 전원 제거 비를 향상시킨 LDO(Low drop-out) 레귤레이터를 제안하였다. LDO 레귤레이터 내부의 오차증폭기와 패스 트랜지스터 사이에 잡음 제거 회로를 두어 전압 라인에서 들어오는 노이즈에 패스 트랜지스터가 받는 영향을 줄일 수 있게 설계하였으며, 기존의 LDO 레귤레이터와 동일한 레귤레이션 특성을 갖도록 했다. 제안한 회로는 0.18um 공정을 사용하였고 Cadence의 Virtuoso, Spectre 시뮬레이터를 사용하였다. In this paper, A low dropout (LDO) regulator that improves the power supply rejection ratio by using a noise canceling circuit is proposed. The noise rejection circuit between the error amplifier and the pass transistor is designed to reduce the influence of the pass transistor on the noise coming from the voltage source. The LDO regulator has the same regulation characteristics as the conventional LDO regulator. The proposed circuit uses 0.18um process and Cadence's Virtuoso and Specter simulator.
Sweet Bee Venom과 일반 봉약침 병행 시술 후 발생한 Anaphylaxis에 대한 증례보고
김채원,이연희,이광호,Kim, Chae-Won,Lee, Yeon-Hee,Lee, Kwang-Ho 대한약침학회 2011 Journal of pharmacopuncture Vol.14 No.4
Objectives: The purpose of this case report are to introduce an Anaphylaxis occurred when using Sweet Bee Venom (SBV) and common Bee Venom (CBC) at the same time and a risk when used SBV and CBC together without skin test. Methods: A patient, an Anaphylaxis occurred when treated her with SBV and CBC at the same time without additional skin test, we observed the progress of the Anaphylaxis with care for her. Results & Conclusions: The Anaphylaxis in the patient was taken a turn for the better by emergency response. Based on this case, Sometimes the use of SBV and CBC at the same time without skin test can be dangerous, and to avoid the risk when used CBC together, in advance allergy test should be conducted.

김채원(Chae-Won Kim),기진영(Jin-Young Ki),김규연(Kyu-Yeon Kim),김지연(Ji-Yeon Kim ),전소영(So-Young Jeon),유제설(Je-Seol Yu) 한국콘텐츠학회 2017 한국콘텐츠학회논문지 Vol.17 No.4
법광원(Forensic Light Source)은 증거물을 훼손하지 않는 비파괴적 방법으로 증거물을 증강하기 위해 주로 사용된다. 현장에 유류된 지문 증거는 사건 해결과 개인 식별을 하는데 있어 매우 중요하다. 다양한 파장 대역의 광원을 사용하면 형광분말이 처리된 지문과 형광시약이 처리된 지문을 증강할 수 있어 실무에서 널리 활용되고 있다. 본 연구에서는 널리 사용되고 있는 아미노산 반응 형광시약인 DFO(1,8-Diazafluoren-9-one)와 1,2-IND(1,2-Indanedione)을 처리한 표준 지문에 레이저 광원과 LED광원을 조사하여 증강 효과를 비교하여 보았다. 비교 결과, 전반적으로 레이저 광원이 LED 광원에 비해 더 나은 지문 증강 효과를 보였다. 하지만, 각 광원은 성능과 휴대의 측면에서 장단점을 가지므로 연구자들은 감식환경과 상황에 따라 레이저 광원과 LED 광원을 상호 보완적으로 사용하는 것을 권고한다. Forensic light source is commonly used for enhancing evidence in a nondestructive way. Latent fingerprints play an important role in an aspect of crime scene investigation. In this study, researchers compared enhancement of standard fingerprints treated with DFO and 1,2-IND in accordance with laser and LED light sources. As a result, laser light source has a better effect rather than LED light sources. However, each light source has strengths and weaknesses in terms of performance and portability. Therefore, researchers that crime scene investigators need to use laser and LED light sources depending on the situation.

본 연구에서는 CFD모사와 실험을 통해 저압막이 병렬 배열된 막모듈로 유입되는 구조를 가진 다지관을 대상으로 수리구조를 개선하여 각 모듈로 유입되는 유입유량을 균등하게 분포시킬 수 있는 방안을 제시하고자 하였다. 모듈로 유입되는 유입유량을 균등하게 분포시킬 수 있는 방안을 CFD로 설계한 결과, 헤더 배관 내에 오리피스 배관을 하나 더 설치하는 이중배관원리를 적용함으로써 다지관에서 막모듈로 유입되는 유입유량의 변동계수가 약 76% 감소됨을 확인 하였다. 또한 CFD의 결과를 검증하기 위한 실험에서도 변동계수가 약 50% 감소함으로써 내부에 요철이 있는 오리피스 내관을 설치하는 것이 효과가 있다는 것을 확인하였다. This study was conducted to suggest the hydraulic modification for improving evenness of inlet flow distribution into the manifold pipe having a structure in which the treated water flows in parallel arranged membrane modules using CFD (Computational Fluid Dynamics) simulation and experiment. From a result of CFD simulation, it was confirmed that the standard deviation of the inlet flows into each membrane module from the manifold pipe was reduced by about 76% by installing other orifice pipe inside header pipe (double piping header). In addition, the experimental results showed that the coefficient of variation was reduced by 50% in the case of double piping header compared to the case of single piping header. Consequently, the design concept of doubling header pipe with rough internal pipe is much effective to improve the evenness of the flow distribution rate in parallel arranged membrane modules.
