간호학과 졸업생들의 간호교육 성과 측정 도구를 규명하기 위하여 시행한 본 연구에서는 의사소통, 전문직관, 지도력, 비판적 사고를 측정하는 도구들을 탐색하여 타당도와 신뢰도를 규명하였다. 의사소통 능력을 측정한 지지적 의사소통 능력 측정 도구의 경우 신뢰도가 Cronbach’s=.78로 비교적 신뢰도가 좋은 것으로 나타났다. 또한 타당도에서는 수렴타당도로 본의사소통 능력과의 상관계수가 .24 (p<.001), 구성타당도로 본집단타당도에서는 다른 학년에 비하여 4학년의 평균점수가 유의하게 높아 의사소통을 측정하는 도구로 활용할 가치가 있다고 판단하였다. 아직 이 도구를 사용한 논문을 찾을 수 없었으나 대인관계를 손상시키지 않으면서 정확하고 정직하게 의사를 전달하면서, 문제를 해결하는 동안 의사소통하는 사람간의 긍정적인 관계를 보존하는 것을 측정하는(Whetten & Cameron, (1998) 본 도구는 인간관계를 중요시하는 간호학의 전인적 간호를 증진시키는 특징이 포함되어 있어 간호학 교육 성과를 측정하는 도구로 활용할 가치가 있다. 또한 수렴타당도를 측정하기 위하여 선택한 의사소통 측정도구보다 문항수가 적어 효율성도 높다. 지금까지 간호학생을 대상으로 의사소통을 측정한 연구들도 면접을 통한 질적인 자료로 측정하거나(LeBlanc et al., 2009), 연구자들이 개발한 도구(Rosenzweig et al., 2008; Yoo & Yoo, 2001)로 측정하고 있어 효율적이면서 객관적인 도구로써 유용할 것으로 생각한다.전문직관은 신뢰도가 Cronbach’s a=.87로 매우 높게 나타났다. 수렴타당도로 본 Yeun 등(2005)이 개발한 간호전문직관과의 상관계수도 .23으로 유의하였고, 구성타당도를 보기위한 집단 비교법에서는 4학년의 점수가 가장 높았으나 유의하게 차이가 있는 학년은 2학년으로 나타나 간호학 교육 성과도구로 채택하는데 큰 문제가 없는 것으로 판단하였다. 항목이 19개로 구성되어 있어 효율성 측면에서 볼 때 Yeun 등(2005)의 도구보다 활용성이 높다. 특히 주위 다른 사람들과 비교하여 자신의 태도를 측정하고 있어 일반적인 간호사에 대한 의견을 묻는 Yeun등(2005)의 도구에 비하여 개인적인 전문직관을 더 민감하게 측정할 것으로 생각한다. 지도력은 신뢰도가 Cronbach’s α=.94로 가장 높았으며 수렴타당도로 본 지도력 도구와의 상관계수도 .16으로 통계적으로 유의하였다. 구성타당도로 본 집단비교에서는 4학년의 점수가 가장 높았으나 유의한 차이가 있는 학년은 2학년이었다. 문항수가 40문항으로 다소 긴 편이어서 효율성이 떨어지기는 하나 간호 실무에서 4년제 학부 학생의 지도력 특성을 측정하기 위해 개발된 도구라는 점에서 활용할 가치가 있다. 비판적 사고를 측정하기 위하여 선택한 Yoon (2004)의 도구는 신뢰도가 Cronbach’s α=.87로 상당히 높은 편이고, 집단비교법에서도 4학년이 다른 학년에 비하여 유의하게 높아 구성타당도도 만족할 만한 수준이었다. 그런데 본 연구자들이 개발한 비판적 사고 기술 도구와의 상관관계가 유의하지 않아 수렴 타당도가 인정되지 않았다. 이는 몇 가지로 해석할 수 있는데 첫째는 비판적 사고 기술과 비판적 사고 성향이 다를 수 있다는 것이다. 즉 Yoon (2004)의 도구는 비판적 사고 성향을 측정하는 도구이고 연구자들이 개발한 도구는 비판적 사고 기술을 측정하는 도구이기 때문이었던 것으로 보인다, 이러한 해석은 비판적 사고 기술과 사고 성향 간에는 유의한 상관관계가 없다는연구 결과가 뒷받침한다(Raymond, Rachel, & Jenny, 2002). 그러나 두 개념간에 상관관계가 있다는 연구결과도 있어(Profetto-Mcgrath, 2003) 이 두 개념 간의 관계에 대한 심층적인 연구가 더 필요하다. 두 번째는 비판적 사고 성향을 측정하는 Yoon (2004)의 도구는 정답이 존재하지 않으나 비판적 사고 기술을 측정하는 도구는 정답이 있는 도구인데 자료를 수집할때 이를 설명하지 않고 측정하여 두 도구의 상관관계가 없는 것으로 나올 가능성도 배제할 수 없다. 성향을 측정하는 것과 달리 정답이 있다고 하는 경우는 본인의 생각과 다르더라도 비판적 사고 기술에 해당하는 내용을 선택할 수 있으나 정답이 없다고 생각하는 경우는 설령 비판적 사고 기술에 해당하는 내용이라고 판단하더라도 본인의 성향과는 다르기 때문에 다른 내용을 선택할 수 있기 때문이다. 또한 성향과 기술이라는 특성이 다른 측면을 측정하는 과정에서 성향은 Likert 척도로 기술은 이분법으로 측정한 것도 상관관계를 떨어뜨린 이유로 보인다. 세 번째는 Yoon (2004)의 도구는 이미 몇 연구에서 사용하여 왔으나 아직도 더 검증이 필요하고, 본 연구자들이 개발한 도구도 신뢰도가 낮아 신뢰도와 타당도를 높이기 위한 작업이 더 필요함을 나타낸다고도 볼 수 있다. 현재 가장 많이 사용하는 도구인 Facione과 Facione (1994)이 개발한 California Critical Thinking Disposition Inventory (CCTDI)를 활용하는 방법도 있으나 75문항으로 긴 편이어서 효율성이 떨어지고 사용하기 위하여 많은 비용을 지불하여야 하므로 비경제적인 측면이 있다. 결론적으로 본 연구에서 규명한 네 도구는 신뢰도와 타당도가 비교적 높게 나타나 간호교육기관에서 사용할 수 있을 것으로 판단하였다. 비판적 사고 측정 도구는 수렴 타당도가 낮게 나와 비판적 기술과 성향을 구분하여 측정하여야 한다고 판단하였다. Purpose: The purpose of this study was to identify and evaluate outcome measurement scales of nursing education such as communication, professionalism, leadership, and critical thinking. Methods: A methodological study design was used to evaluate the reliability and validity of the scales. Survey was done to the students (n=407) enrolled in baccalaureate nursing schools. Using convenience sampling method, we tried to include all grades of students. Internal consistency, convergent validity and group comparison were used to evaluate the reliability and validity of the scales. Results: All scales were reliable and valid. Only convergent validity of the scale to measure critical thinking was relatively low. It suggested that critical thinking skill and disposition might be measured separately. Also it was inefficient to measure the nursing education outcomes with separate scales. Conclusions: It is recommended to develop a new integrative scale to measure nursing education outcomes. Also it is necessary to set the norm of nursing students to evaluate nursing education outcomes for the quality control of nursing education.

Prediction of Transonic Buffet Onset for a Supercritical Airfoil with Shock-Boundary Layer Interactions Using Navier-Stokes Solver

Injae Chung 한국항공우주학회 2017 International Journal of Aeronautical and Space Sc Vol.18 No.1

To predict the transonic buffet onset for a supercritical airfoil with shock-boundary layer interactions, a practical steady approach has been proposed. In this study, it is assumed that the airfoil flow is steady even when buffet onset occurs. Steady Navier-Stokes computations are performed on the supercritical airfoil. Using the aerodynamic parameters calculated from Navier-Stokes solver, various steady approaches for predicting buffet onset are discussed. Among the various steady approaches considered in this study, Thomas’ criterion based on Navier-Stokes computation has shown to be the most appropriate indicator of identifying the buffet onset for a supercritical airfoil with shock-boundary layer interactions. Good agreements have been obtained compared with the results of unsteady transonic wind tunnel tests. The present method is shown to be reliable and useful for transonic buffet onset for a supercritical airfoil with shock-boundary layer interactions in terms of practical engineering viewpoint.

Molecular Mechanisms of Regulation of Human Cytochrome P4501A2 Gene Expression

Injae Chung 한국생약학회 2004 Natural Product Sciences Vol.10 No.5

Cytochrome P4501A2 (CYP1A2) is responsible for the metabolic activation of a number of aromatic amines and amides to mutagenic and carcinogenic moieties. Considerable variations in the level of CYP1A2 expression in humans have been reported. Thus, the level of human CYP1A2 may determine an individuals susceptibility to these chemicals. Given its importance, the molecular mechanisms of CYP1A2 regulation have been studied by many groups. Direct interactions between transcription factors with the promoters of the gene represent one of the primary means by which the expression of CYP1A2 is controlled. In this review, several important cis elements, transcription factors and the effects of deacetylation/methylation of promoter regions that play an important role in the induction by PAHs as well as constitutive expression of human CYP1A2 are discussed.

Exploring Diversity among Rice Germplasms based on Their Physiological Traits Responses to Salinity

Inja Naga Bheema Lingeswar Reddy,이숙영,박용진,권택륜 한국작물학회 2017 Journal of crop science and biotechnology Vol.20 No.2

Salinity is one of the major abiotic stresses that severely effects rice production throughout the world. Previously, there have not been many studies which focused on studying diversity among rice germplasm based on specific physiological traits for salt tolerance. Our diversity study was based on physiological traits such as Na+ concentration, K+ concentration, K+/Na+ ratio, osmotic potential, and biomass which are major components determining salt tolerance. This study has systematically analyzed phenotypic data of 191 germplasms in two different salt concentrations apart from the control. The current study identified salt tolerant germplasms based on their response to a single physiological trait as well as a combination of different physiological traits. Some of the germplasm identified outperformed known salt tolerant cultivar Pokkali. This study identifies correlation among various physiological traits. The salt tolerant germplasms can be taken forward into developingbetter varieties by conventional breeding and exploring genes for salt tolerance.

My Carbohydrate Story

Glycan-associated recognition events in cells and organisms are not only critical for diverse physiological processes, but they are also involved in various pathological processes. Therefore, elucidation of glycan-mediated biomolecular interactions and their consequences is of great importance in basic biological research and biomedical applications. In 2002, we and others were the first to employ high-density glycan microarrays in efforts aimed at the high-throughput assessments of glycan-associated recognition events. As they include many glycans attached in a dense and orderly manner to a solid surface, glycan microarrays allow for multiple parallel analyses of glycan-protein binding events by utilizing only small amounts of glycan samples. Therefore, this microarray technology has become a leading edge tool in studies aimed at elucidating roles played by glycans and glycan binding proteins in biological systems. In this presentation, I will discuss our efforts on the construction of glycan microarrays and their applications in studies of glycan-associated interactions. Immobilization strategies of functionalized and unmodified glycans on derivatized glass surfaces will be discussed. Although others have developed immobilization techniques, our efforts have focused on improving the efficiencies and operational simplicity of microarray construction. The microarray-based technology has been most extensively used for rapid analysis of the glycan binding properties of proteins. In addition, glycan microarrays have been employed to determine glycan–protein interactions quantitatively, detect pathogens and rapidly assess substrate specificities of carbohydrate-processing enzymes. More recently, the microarrays have been employed to identify functional glycans that elicit cell surface lectin-mediated cellular responses.

Unidirectional Ring Ethernet and Media Access Controller with Automatic Relaying for Low-complexity In-vehicle Control Network

Injae Yoo,Jihyuck Jo,Youngjin Ju,In-Cheol Park 대한전자공학회 2017 Journal of semiconductor technology and science Vol.17 No.5

This paper proposes an Ethernet-based invehicle control network and its hardware realization. Since modern premium-class vehicles contain nearly a hundred electronic control units (ECUs), multiple control networks needed for the ECUs become considerably complex. In order to reduce the network complexity, the proposed network connects the ECUs by employing an Ethernet-based unidirectional ring topology. In addition, a new Ethernet media access controller (MAC) is proposed to automatically relay mismatched frames. As a result, the proposed ring network can be constructed without any switching device. A hardware platform employing the proposed MAC as a network controller is implemented on a field programmable gate array to evaluate the realistic performance of the proposed network. Experimental results show that the proposed MAC increases the communication speed by 123%. Moreover, the performance of the proposed network with a large number of ECU nodes is evaluated using the OMNET++ simulation tool, which shows that the proposed network provides the ECUs with much higher communication speed than the conventional CAN and FlexRay do.

Speech Intelligibility of Korean EFL Learners : Role of Proficiency, Text Type and Text Length

Injae Lim,Jeong-Im Han,Taehwan Choi,Joo-Kyeong Lee 아시아영어교육학회 2016 The Journal of Asia TEFL Vol.13 No.4

The purpose of this study was to investigate whether and to what extent the intelligibility of Korean EFL learners’ speech at the text level is affected by their English proficiency, text type, and text length. Various speech materials produced by native English speakers and two Korean EFL speaker groups (high vs. low proficiency) were presented to native English listeners and two Korean EFL listener groups, respectively, for comparison of intelligibility scores. The results showed that the listeners’ overall proficiency played the most critical role in determining the level of speech intelligibility for all speaker groups, regardless of the type and length of speech materials. The speakers’ proficiency level in terms of pronunciation, however, had no significant effect. As for the text type, dialogue texts were consistently more intelligible than monologues to all listener groups while the effect of text length varied depending on the text type. These results suggest that L2 learners’ speech intelligibility needs to be examined within the context of natural L2 text beyond word- and sentence-level utterances in consideration of the interaction of text-related features and other learner variables. Some pedagogical implications are also discussed.
