This study aimed to clarify the effects of nursing students' major selection motivation on their career decision making self-efficacy and major satisfaction. For the goal, the study made a questionnaire survey of 300 nursing students in their 3rd or 4th year of a college in J City. 285 sheets were finally analyzed using the SPSS 25 Program. The findings of this research are as follows. Concerning general characteristics, there's a significant difference in influence on the abovementioned self-efficacy between personality and school satisfaction. Major satisfaction significantly varied depending on school satisfaction. There were significantly positive correlations existed between major selection motivation, and major satisfaction. Either intrinsic or extrinsic motivation affected the foresaid self-efficacy and major satisfaction in a significant, positive way. Regarding the influence of factors of major satisfaction on those of major selection motivation, curriculum and perception satisfaction had significant effects on intrinsic motivation as well as extrinsic one, while relationship satisfaction had such effect only on intrinsic motivation. These findings suggest that strategies for raising nursing students' major selection motivation should be taken, resultantly improving their career decision making self-efficacy and major satisfaction.

This research aims to analyze the process of selecting, maintaining, and changing the method of learning mathematics by middle school students from the perspective of self-regulated learning ability, in order to help students to select a rational method of studying. For this purpose, we defined 'assisted-learning' as all kinds of education that education demanders receive to supplement their regular school studies. As results of the research, it was found as follows. First, the students with high self-regulated learning ability selected, maintained, and changed their assisted-learning based on their concrete decision and rational reasons regarding the effect of their learning process and assisted-learning to themselves. Second, the students with high self-regulated learning ability had tendency to be very active participation in class than the students with low ability. Third, the students with high self-regulated learning ability felt the effect of assisted-learning on their learning mathematics, and felt the enhancement of their interest and confidence. Also, it is notable that the students selected 'their own willingness to study' as a major factor for the success of assisted-learning.

The purpose of this study is to understand student's reading motivation by laying out self-selected reading program and running it at school libraries. The self-selected reading program based on self-determination theory ensures the autonomy of book selection. The self-selected reading program in this study provided a number of scope and recommended book lists in order to ensure the autonomy of book selection and developed integrated reading and writing. After finishing this program, the author measured 6 domains of reading motivation with participated students who completed this course. As a result, it turned out that autonomous motive domains excessively surpassed heteronomous motive domains. Such autonomy of book selection, one of the key features from self-selected reading programs, is expected to help making the best use of school library collections by recommended book lists and stimulating stable and sustainable reading habits driven by self-motivation.

How an individual construes one's future influences everyday decisions. For example, savings and impulsive purchasing, which is highly familiar with our life, are related to future time perception. Drawing on the idea of future self-continuity, the perceived connectedness between the current and future self, this study demonstrated whether media images with various age ranges influence a sense of connectedness with one's future self as well as impatience. Furthermore, the study measured whether these relationships were moderated by the positivity of older adults and an individual's dispositional optimism in general. Results showed that watching various images of people with a wide range of age (from the 20s to 90s) in social media increased young adults' (the 20s) self-continuity and decreased their intention of impatient consumption. This effect was also moderated by the degree to which the participants perceive aging positively.

자기정렬구조의 실리콘-게르마늄 이종접합 트랜지스터에서 $f_{max}$를 높이기 위한 방안으로 베이스의 저항 값을 감소시키고자 외부 베이스에 실리콘 및 실리콘-게르마늄 박막을 저온에서 선택적으로 성장할 수 있는 방법을 연구하였다. RPCVD를 이용하여 $SiH_{2}Cl_{2}$과 $GeH_{4}$를 소스 가스로 하고 HCI을 첨가하여 선택성을 향상시킴으로써 $675\sim725^{\circ}C$의 저온에서도 실리콘 및 실리콘-게르마늄의 선택적 에피성장이 가능하였다. 고온 공정에 주로 이용되는 $SiH_{2}Cl_{2}$를 이용한 실리콘 증착은 $675^{\circ}C$에서 열분해가 잘 이루어지지 않고 HCl의 첨가에 의한 식각반응이 동시에 진행되어 실리콘 기판에서도 증착이 진행되지 않으나 $700^{\circ}C$ 이상에서는 HCI을 첨가한 경우에 한해서 선택성이 유지되면서 실리콘의 성장이 이루어졌다, 반면 실리콘-게르마늄막은 실리콘에 비해 열분해 온도가 낮고 GeO를 형성하여 잠입시간을 지연하는 효과가 있는 게르마늄의 특성으로 인해 선택성이나 증착속도 모두에서 유리하였으나 실리사이드 공정시에 표면으로 게르마늄이 석출되는 현상 등의 저항성분이 크게 작용하여 실리콘-게르마늄막 만으로는 외부 베이스에의 적용은 적절하지 않았다. 그러나 실리콘막을 실리콘-게르마늄막 위에 Cap 층으로 증착하거나 실리콘막 만으로 외부 베이스에 선택적으로 증착하여 베이스의 저항을 70% 가량 감소시킬 수 있었다.

바이오센서는 효소(enzyme), 생분자(biomolecule), 항체(antibody), 세포(cell) 등의 biological agent를 인지 물질(recognition material)로 하여 측정하고자하는 분석 대상(analyte)과 높은 선택성으로 반응을 일으키게 하여 그 결과를 기존의 물리, 화학센서로 감지 해내는 방식이므로 기존의 의료용 화학센서를 대체하는 추세이다. 바이오센서가 기존의 센서와 구별되는 점은 생물질의 선택적인 반응 및 결합을 이용하는 것이므로 바이오센서의 실용화에 있어서 가장 중요한 것은 생체 반응 물질의 고정화 기술과 고정화막의 선택이라 할 수 있다. 일정전압법을 이용한 요소센서는 많이 연구되어 오고 있으나 낮은 농도에서의 감도저하에 따른 단점으로 상용화에 이르지 못하고 있다. 본 논문은 요소센서의 이용하기 위한 고정화막으로 3-mercaptopropionic acid 자기조립 단인층의 전기화학적 특성을 고창하였다. 자기조립 단일층은 직접적인 전자전달로 인하여 낮은 요소 농도에서 뛰어난 강도와 빠른 반응 시간을 보였으며, 특히 다공질 실라콘을 기질로 사용한 경우 평면 전극 보다 약 3배의 감도 증가 효과를 가져왔다. 자기조립 단일층의 표면 분석은 X-ray photoelectron spectroscopy(XPS)를 이용하였다.

In this paper, the wage equations of local labor markets for college graduates in Korea are estimated by Dahl(2002)'s methodology to correct for selection bias. The results suggest that the variations of coefficients in wage equations across the local labor markets are mostly remained after correcting for selection bias. The gender wage gap is hardly affected by selection bias. The variations of return to education and the major premium are reduced about 18% and 11% respectively. Meanwhile, the selection bias is negligible in the national capital region, which suggests that college graduates prefer the national capital region regardless of their gender, level of education, and major.

Vector autoregressive (VAR) models in high dimension suffer from noisy estimates, unstable predictions and hard interpretation. Consequently, the sparse vector autoregressive (sVAR) model, which forces many small coefficients in VAR to exactly zero, has been suggested and proven effective for the modeling of high dimensional time series data. This paper studies coupling measures to select non-zero coefficients in sVAR. The basic idea based on the simulation study reveals that removing the effect of other variables greatly improves the performance of coupling measures. sVAR model coefficients are asymmetric; therefore, asymmetric coupling measures such as Granger causality improve computational costs. We propose two asymmetric coupling measures, filtered-cross-correlation and filtered-Granger-causality, based on the filtered residuals series. Our proposed coupling measures are proven adequate for heavy-tailed and high order sVAR models in the simulation study.
