손대호 ( Daeho Son ),서현아 ( Hyunah Seo ) 사단법인 아시아문화학술원 2021 인문사회 21 Vol.12 No.1
본 연구는 유아교사의 조직문화 및 조직건강성과 삶의 질 간의 관계를 인식하고 재미 지각의 매개 효과를 알아보려는 목적으로 실시되었다. B시 및 G도에 소재한 유아교사 255명을 대상으로 조직문화, 조직건강성, 재미지각, 삶의 질과 관련한 척도에 설문 응답하도록 하였다. 수집된 자료는 Jamovi 1.1.7.0버전를 활용하여 Pearson의 적률상관분석, 경로관계와 매개효과 검정을 실시하였다. 연구결과는 다음과 같다. 첫째, 조직문화와 조직건강성이 높을수록 재미지각이 높아졌다. 둘째, 조직문화와 조직건강성이 높아질수록 삶의 질이 높아졌다. 셋째, 재미지각이 높아질수록 삶의 질이 높아졌다. 넷째, 조직문화 및 조직건강성과 삶의 질 간의 관계에서 재미지각은 각각 부분매개효과를 나타내었다. 유아교사 삶의 질에 영향을 미치는 조직 차원의 변인과 개인 차원의 변인 간의 구조적 관계를 밝힘으로써 유아교사의 삶의 질 개선을 위한 기초자료로 제공될 것으로 기대한다. The purpose of This study was conducted with the aim of recognizing the relationship between organizational culture and organizational healthiness and quality of life of early childhood teachers and the mediating effect of fun perception. 255 early teachers in B city and G province were asked to respond to measures related to organizational culture, organizational healthiness, perception of fun, and quality of life. The collected data are based on the Jamovi version 1.1.7.0 to perform Pearson’s aptitude correlation analysis, path relationships and mediated effects tests. The results of the study are as follows. First, the higher the organizational culture and organizational healthiness, the higher the perception of fun. Second, the higher the organizational culture and organizational healthiness, the higher the quality of life. Third, the higher the perception of fun, the higher the quality of life. Fourth, in the relationship between organizational culture and organizational healthiness and quality of life, the perception of fun has shown a partial-mediated effect, respectively. It is expected that it will be provided as a basic data for improving the quality of life of early childhood teachers by revealing the structural relationship between organizational and individual-level variables that affect the quality of life of early childhood teachers.

<P>An aluminum-antimony alloy (Al-Sb) composite with a novel nanostructure was fabricated by high-energy ball milling (HEBM), and the composite was explored as an anode material for lithium-ion (Li-ion) and sodium-ion (Na-ion) batteries. HEBM treatment of Al and Sb in the absence of carbon generated the pure AlSb alloy. On the other hand, when the nanocomposite was prepared with carbon, the final product was Sb@AlxCy-C, where Sb nanocrystallites were dispersed in a hybrid matrix consisting of amorphous AlxCy and carbon. Comparison of the electrochemical performances of the AlSb and Sb@AlxCy-C electrodes showed that the composite with the hybrid matrix exhibited better cyclability and rate capability in both the Li-ion and Na-ion batteries. Specifically, the use of the Sb@AlxCy-C anode in the Li-ion and Na-ion batteries resulted in stable specific capacity, corresponding to similar to 400 mAh g(-1) and similar to 160 mAh g(-1), respectively, at the 100th cycle, and also gave rise to a high rate capability of similar to 60% for the Li-ion battery and similar to 70% for the Na-ion battery at 3,000 mA g(-1). This enhanced performance can be attributed to the hybrid matrix comprised of AlxCy-C, which acts as an effective buffer for large volume expansion during lithiation and sodiation.</P>
Hydrogen-Affected Tensile and Fatigue Properties of Ti-6Al-4V Sheets by Superplastic Forming

Abstract: Mill-annealed Ti-6Al-4V (Ti64) sheets were formed into rectangular shaped pans with two square recesses by the superplastic forming (SPF) technique under high pressure using commercial grade argon gas. The SPF process induced a significant decrease in the tensile ductility and high cycle fatigue (HCF) resistance of the Ti64 alloy. The fractographic analysis of as-fabricated Ti64 sheets showed a hydrogen-affected layer on the surface, possibly incurred by a small amount of water vapor in the commercial grade argon gas. This hydrogen-affected layer with a depth of approximately 60 μm tended to decrease tensile ductility and the resistance to HCF, by encouraging easy crack initiation on the surface. The effect of hydrogen on the mechanical properties of the SPF processed Ti64 sheets was discussed based on fractographic and micrographic observations. (Received May 8, 2017; Accepted May 19, 2017)

We have studied nonvolatile memory properties of MOSFETs with double-stacked Si nanoclusters in the oxide-gate stacks. We formed Si nanoclusters of a uniform size distribution on a 5 nm-thick tunneling oxide layer, followed by a 10 nm-thick intermediate oxide and a second layer of Si nanoclusters by using LPCVD system. We then investigated the memory characteristics of the MOSFET and observed that the charge retention time of a double-stacked Si nanocluster MOSFET was longer than that of a single-layer device. We also found that the double-stacked Si nanocluster MOSFET is suitable for use as a dual-bit memory.
