본 연구는 예비유아교사의 학업적 자기효능감과 그릿이 행복감에 어떠한 영향력을 미치는지 확인하는 데 목적이 있다. 이를 위해 부산광역시, 울산광역시, 경상남도 내에 소재하고 있는 대학교의 유아교육과에 재학 중인 예비유아교사 300명을 임의표집하여 연구대상으로 선정하였다. 예비유아교사의 학업적 자기효능감을 측정하기 위해 김아영, 박인영(2001)이 개발하고 타당화한 후 김병만, 김정주, 윤정진(2017)이 수정하여 사용한 학업적 자기효능감 검사도구를 사용하였다. 고, 그릿을 측정하기 위해 Duckworth, Peterson, Matthews와 Kelly(2007)가 개발한 Original Grit Scale(Grit-O)를 이수란(2014)이 한국실정에 맞게 번안한 척도를 사용하였으며, 행복감을 측정하기 위해 Seligman(2011)의 웰빙에 대한 PERMA 이론을 토대로 Butler와 Kern(2014)이 개발하여 김미진(2015)이 번안한 다차원적행복척도(Multidimensional Measure of Flourishing: MMF)를 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감에 대한 인식에 대한 결과로 모든 변인에서 보통 이상의 긍정적인 인식 정도가 나타났다. 둘째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감 간의 상관관계에는 유의미한 정적 상관관계가 있음을 알 수 있다. 셋째, 예비유아교사의 학업적 자기효능감은 예비유아교사의 행복감에 영향을 미치는 변인으로 나타났으나, 그릿은 예비유아교사의 행복감에 영향을 미치지 않는 변인으로 나타났다. The purpose of this study is to investigate the influence of pre-service early childhood teachers academic self-efficacy and grit on happiness. For this purpose, 300 Pre-service early childhood teachers in preschool education at universities located in Busan, Ulsan and Gyeongsangnam province were randomly sampled and selected. In order to measure the pre-service early childhood teachers academic self-efficacy, I used the academic self-efficacy test tool modified by Kim Byung-man, Kim Jung-ju and Youn Jung-jin (2017) after the development and validation of Kim Ae-Young and Park In-Young (2001). The original Grit Scale (Grit-O) developed by Duckworth, Peterson, Matthews and Kelly (2007) was used to measure grit. And to measure happiness, we used the multidimensional happiness scale developed by Butler and Kern (2014) and developed by Kim Mi-jin (2015) based on the PERMA theory of wellness in Seligman (2011). The results of this study are as follows. First, as a result of pre-service early childhood teachers perception of academic self-efficacy, grit, and happiness, positive perceptions were more than usual in all variables. Second, there is a significant positive correlation between the pre-service teacher s academic self-efficacy, grit, and happiness. Third, the academic self-efficacy of pre-service early childhood teachers was a factor affecting the happiness of pre-service early childhood teachers. Specifically, it was found that task difficulty preference, self-regulated efficacy, and self-confidence affect the happiness of pre-service early childhood teachers among the sub-variables of happiness. However, the sub-variables of Grit did not affect the pre-service teachers happiness.

Recently, variety of organic and inorganic hybrid materials have recently investigated as alternative routes to SiOC, $SiO_2$ thin film formation at low temperatures for applications in electronic ceramics. Specially, silicon based polymers, such as polycarbosilane, polysilane and polysilazane derivatives have been studied for use in electronic ceramics and have been applied as dielectric or insulating materials. In this study, Polycarbosilane(PCS), which Si-$CH_2$-Si bonds build up the backbone of the polymer, has been investigated as low-k materials using a solution process. After heat treatment at 350$^{\circ}C$ under $N_2$ atmosphere, chemical composition and dielectric constant of the thin film were $SiO_{0.27}C_{1.94}$ and 1.2, respectively. Mechanical property measured using nanoindentor shows 1.37 GPa.

1. Objectives Benign Paroxysmal Positional Vertigo (BPPV) is thought to be due to debris which has collected within a part of the inner ear. It is best characterized by true vertigo and geotropic nystagmus that occur a few seconds after specific head movements. The symptoms of BPPV include dizziness or vertigo, lightheadedness, imbalance, and nausea. The vertigo usually lasts no more than a minute. This study is reported to evaluate the effect of Geopung-san(祛風散) to patient with vertigo. 2. Methods This patient was treated by Geopung-san(祛風散) and Acupuncture, who was diagnosed as Soeumin interior disease. We used Visual analogue scale(VAS) for the assessment of vertigo. 3. Results This patient's main symptom is vertigo according to head movement with nausea and vomiting. So she was treated by Geopung-san(祛風散) in "Dongyisasangsinpyun(東醫四象新編)" and showed a positive response about her problems. 4. Conclusions We suggest that Geopung-san(祛風散) is effected significantly to patient with vertigo, but then we consider that studies about the case like this are more needed.

Effect of Tween 20 on the Penetration of Ketoprofen through Excised Rat Skin

김정주,지상철,심창구,김종국,Kim, Jung-Ju,Chi, Sang-Cheol,Shim, Chang-Koo,Kim, Chong-Kook 한국약제학회 1992 Journal of Pharmaceutical Investigation Vol.22 No.2

The effect of Tween 20 on the penetration of ketoprofen in aqueous vehicles through excised rat skin has been evaluated. The addition of Tween 20, up to 2%, in water containing ketoprofen decreased the penetration of ketoprofen through the skin compared with the reference vehicle without this surfactant. However, the addition of Tween 20 in ketoprofen aqueous vehicle increased diffusion parameter significantly which was compensated with the lowered partition parameter.

1. Objectives : There are many studies on the ordinary symptoms based on Sasang constitution. But there are not quite satisfactory between the types of Sasang constitution. So This study is for learning the characteristics of ordinary symptoms depending on Taeyangin Soyangin(the rest Yangin) and Taeumin Soeumin(the rest Eumin) of the Sasang constitution. 2. Methods : We classified them into the each type of Sasang Constitutional Medicine(SCM) by the well-trained SCM specialist, and assessed their ordinary features by the questionnaire. Binary logistic regression analysis was applied to evaluate the influence of ordinary features to the diagnosis of SCM. 3. Results : There are a result of the binary logistic analysis on the observed questionnaire. 1) Regarding sleeping, Yangin do not dream much as Eumin do when they sleep. The time they are sleeping is not longer, and they usually do not sleep well. 2) Regarding stools, Yangin go to stool more than Eumin do. The constipation does not occur when they are not in a good condition, and they do not feel uncomfortable when they do not go to stool for a day. The length of time taken for emptying the bowels is much longer, and the hardness of their stools is much more, but the hardness does not mean that they have the constipation. 3) Regarding urine, Yangin have much more foam than Eumin. 4. Conclusions: We found that Yangin and Eumin have characteristics of ordinary symptoms, but partly there are not in accordance with ones what Lee Je-ma said in his book. So in future we hope clinical studies are required steadily.

WRAN 응용을 위한 하향링크 무선전송 방식 : OFDMA 상황인식 시스템에서의 적응 부채널 할당 및 고정 빔 형성 기법

김정주,고상준,장경희,Kim Jung-Ju,Ko Sang-Jun,Chang Kyung-Hi 한국통신학회 2006 韓國通信學會論文誌 Vol.31 No.3A

In this paper, we analyze functional requirements of the IEEE 802.22 WRAN, and propose a downlink 프레임 structure satisfying the requirements. The proposed downlink 프레임 structure maximizes e transmission efficiency by adopting the cognative radio to assign the sub-channel by reflecting the channel environment of WRAN. We also calculate the signalling overhead for both downlink and uplink, and analyze the performances of time synchronization, frequency synchronization and cell identification based on the 프리앰블 in downlink and suggest the channel estimation method tough 프리앰블 or pilot. As a final result, e stationary beamforming (SBF) algorithm with dynamic channel allocation(DCA) is proposed. The proposed OFDMA downlink 프레임 structure with channel adaptive sub-channel allocation for cognitive radio applications is verified to meet the requirements of IEEE 802.22 WRAN, by computer simulations. 본 논문에서는 현재 진행 중인 IEEE 802.22 WRAN의 Functional Requirements를 분석하고, 제시된 Requirements를 만족시키는 하향링크 프레임 구조를 제안한다. 제안된 하향링크 프레임 구조는 WRAN 각 채널 환경하에서의 상황인식 적응 Traffic Channel에 의한 Rate Control을 수행하여 전송 효율을 극대화시키며, 이를 위한 하항링크와 상향링크의 Signaling Overhead를 계산한다. 그리고, 하링링크의 프리앰블을 이용한 시간, 주파수동기 및 셀 ID 탐색 성능을 분석하고, 프리앰블 또는 Pilot에 의한 환경 적응적 채널 추정 방법과 동적채널할당(Dynamic Channel Allocation)을 결합한 고정 빔형성(Stationary Beamforming) 알고리즘을 제안한다. 또한, 모의실험을 통하여 이와 같이 제안된 무선 채널 환경에서 적응 부채널 할당 기능을 고려한 상황인식 하향링크 프레임구조가 IEEE 802.22 WRAN 시스템의 요구사항을 만족시킴을 검증한다.
