청루(Cheng, Lu),정정희(Chung, Chung-Hee),이근영(Lee, Keun-Young) 한국어린이문학교육학회 2021 어린이문학교육연구 Vol.22 No.3

본 연구에서는 유아교사의 놀이성과 셀프리더십 및 놀이교수효능감 간의 관계를 탐색하고, 놀이성이 놀이교수효능감에 미치는 영향에서 셀프리더십의 매개효과를 알아보고자 하였다. 이를 위해 D시 소재의 유치원과 어린이집 교사 220명을 대상으로 놀이성, 셀프리더십, 그리고 놀이교수효능감에 대한 설문조사를 수행한 뒤, 수집된 자료를 분석하였다. 우선, 유아교사의 놀이성과 셀프리더십, 놀이교수효능감 간의 상관관계를 알아보기 위해 Pearson 적률상관관계 분석을 실시하였으며, 매개효과를 검증하기 위해 중다회귀분석을 실시하였다. 그리고 매개효과의 구체적인 통계적 의도를 밝히기 위해 Sobel test를 실시하였다. 연구결과에 따르면 첫째, 놀이성, 셀프리더십, 그리고 놀이교수 효능감의 총합과 각각의 하위요인 간에 유의미한 정적 상관관계가 있는 것으로 나타났다. 둘째, 유아교사의 놀이성이 놀이교수효능감에 미치는 영향에서 셀프리더십이 부분매개하는 효과를 가지고 있는 것으로 나타났다. 이를 통해 유아교사의 놀이성에 셀프리더십이 매개되었을 경우 놀이교수효능감이 더욱 높아진다는 것을 확인할 수 있었다. 이러한 결과는 놀이교수효능감을 증진시키기 위해서는 교사의 긍정적인 놀이성 뿐만 아니라 셀프리더십도 함께 고려되어야 한다는 점을 시사한다. In this study, we explored the relationship between playfulness, self-leadership, and play teaching efficacy of early childhood teachers, and we wanted to determine the mediating effects of self-leadership in the influence of playfulness on the effectiveness of play teaching efficacy. For this end, a survey was conducted on playfulness, self-leadership, and play teaching efficacy among 220 teachers at kindergartens and daycare centers located in D city, First, a Pearson moment correlation analysis was conducted to find out the correlation between the early childhood teachers’ playfulness, self-leadership, and play teaching efficacy, and multiple regression analysis was performed to verify the mediating effect. In addition, the Sobel test was conducted to reveal the specific statistical intention of the mediating effect. The main results of this study were as follows: first, there was a significant positive correlation between the overall playfulness, self-leadership, and play teaching efficacy and each of their sub-factors. Second, it was found that self-leadership had a partial mediating effect in the effect of early childhood teachers’ playfulness on play teaching efficacy. Through this, it was confirmed that when self-leadership was mediated in playfulness, play teaching efficacy was further increased. These finding suggests that not only positive playfulness of teachers but also self-leadership should be considered to enhance play teaching efficacy.

A Corpus Analysis of Temporal Adverbs and Verb Tenses Cooccurrence in Spanish, English, and Chinese

Cheng, An Chung,Lu, Hui-Chuan Institute for Corpus Research 2022 Asia pacific journal of corpus research Vol.3 No.2

This study investigates the cooccurrence between temporal adverbs and grammatical tenses in Spanish and contrasts temporal specifications across Spanish, English, and Chinese. Based on a monolingual Spanish corpus and a trilingual parallel corpus, the study identified the top ten frequent single-word temporal adverbs collocating with grammatical tenses in Spanish. It also contrasted the cooccurrence of temporal adverbs and verb tenses in three languages. The results show that aun 'still', hoy 'today', and ahora 'now' collocate with the present tense at more than 80%. Ayer 'yesterday' and finalmente 'finally' cooccurring with the simple past tense are at 84% and 69%, respectively. Then, mientras 'meanwhile' collocates with the past imperfect at 55%, the highest of all. Mañana 'tomorrow' cooccurs with the future and present tenses at 34%. Other adverbs, ya 'already', siempre 'always', and nuevamete 'again', do not present a strong cooccurrence tendency with a tense overall. The contrastive analysis of the trilingual parallel corpus shows a comprehensive view of temporal specifications in the three languages. However, no clear one-to-one mapping pattern of the cooccurrence across the three languages can be concluded, which provides helpful insights for second language instruction with natural language data rather than intuition. Future research with larger corpora is needed.

Objective: To investigate the effect of vascular endothelial growth factor (VEGF) and fibroblast growth factor 2 (FGF2) on revascularization, survival, and oocyte quality of cryopreserved, subcutaneously transplanted mouse ovarian tissue. Methods: Outbred ICR mice (n = 112) were used as the animal model. Vitrified mouse ovarian tissues were treated without (control group) or with VEGF and FGF2 before autologous subcutaneous transplantation. After transplantation for 2 or 3 weeks, grafts’ survival, angiogenesis, and oocyte quality were examined. Results: VEGF and FGF2 promoted revascularization and significantly increased the survival rate of subcutaneously transplanted cryopreserved ovarian tissues compared with the untreated grafted control. The two growth factors did not show long-term effects on the ovarian grafts. In contrast to the untreated ovarian grafts, active folliculogenesis was revealed as the number of various follicles was significantly higher or had an increased trend in the VEGF and FGF2-treated ones. Though the fertilization rate had no differences between VEGF/FGF2 and control group; however, the oocyte quality was much better in the VEGF/FGF2-treated grafts as demonstrated by the higher ratio of blastocyst development. Conclusions: Introducing of angiogenic factors such as VEGF and FGF2 may be a promising strategy to improve revascularization, survival, and oocyte quality of cryopreserved, subcutaneously transplanted mouse ovarian tissue.

The Acquisition of Spanish Clitic Pronouns as a Third Language: A Corpus-based Study

Lu, Hui-Chuan,Cheng, An Chung,Chu, Yu-Hsin Institute for Corpus Research 2020 Asia pacific journal of corpus research Vol.1 No.2

This corpus-based study investigated third language acquisition by Taiwanese college students in learning Spanish clitic pronouns at beginning and intermediate levels. It examined the acquisition sequences of Spanish clitic pronouns of the Chinese-speaking learners whose second language was English and third language was Spanish. The results indicated that indirect object pronouns (OP) preceded direct OP (case), first person preceded third person OP (person), masculine preceded feminine OP (gender), and animate preceded inanimate OP (animacy). The findings presented similar patterns as those of previous studies on English-speaking learners of Spanish. In further comparisons of the target forms in Chinese, English, and Spanish, the results suggested that L1 Chinese had strong influence on L3 Spanish, which accounts for the challenges that Taiwanese learners of Spanish face as they learn the Spanish clitic pronouns in the beginning stage.

중국 주거문화와 가정교육을 융합한 주거 공간에서의 교육행위 특성 연구

고성림(Gao Cheng Lin),노박문(Lu Bo Wen),정미선(Chung Mi Sun) 한국전시산업융합연구원 2019 한국과학예술융합학회 Vol.37 No.3

본 논문은 중국 주거문화의 교육 속성을 기초 연구대상으로 하여, 주거 공간에서의 “상(象)”(무형)과 문화적 사상, 심미(审美), 상징과 “형(形)”(유형)문의 공간을 표현, 장식적 상징성을 융합 및 연구하였다. 각 요소가 반영된 주거공간의 특성과 가정교육의 연관성을 기준으로 분석하였다. 또한 중국의 전통 주거공간(명청시대를 대표하는 삼진사합원(三进四合院)) 과 현대 주거공간(20세기 말의 공동주택)에서의 교육행위 특성을 비교하고, 주거공간 설계에서의 교육의 중요성을 강조하여 “덕육(德育)”교육과 학습 성장의 연관성, 교육의 역할, 교육 공간, 정경체험(情景体验) 특성의 차이성 등을 도출해내어 미래 주거 공간에서 가정교육 공간의 디자인 방향의 근거를 제시하고 있다는 점에서 의의가 있다. 연구과정과 내용은 다음과 같다. 첫 번째, 중국 주거문화와 가정교육의 융합성을 바탕으로 주거공간의 “상(象)”(무형)문화와 “형(形)” 문화 두 가지 측면에서 출발하여, 사상, 심미, 상징, 공간표현, 장식의 5가지 측면에서 문화적 배경에 기초한 주택공간과 교육특성의 상관성을 연구 분석한다. 둘째, 전통주거공간과 현재주거공간의 교육적 속성에 기초하여 "상(象)"문화에서는 조상 숭배, 존비유서(尊卑有序), 장유유서, 남녀유별, 좌북남조(坐坎朝离), 사법자연(师法自然:자연에서 배우다), 경중구분, 도덕품격 등의 8개 요소, 그리고 "형(形)"문화에서는 향심성(向心性), 방향성, 주거공간의 내외부, 실내공간의 방과 방, 문양 등의 5개요소를 기준으로 하여 분석하였다. 셋째, 위에서의 과정을 통해 전통과 현대 주거 공간에서의 교육적 특성을 구체적으로 비교 분석하고, 전통 주택 공간에서 가풍가규(家风家规), 학규(学规)성장, 품행 가치와 현대주택 공간에서의 가족 문화, 학습 성장, 사회적 가치 등의 6가지 측면의 통일성과 차이점을 도출한다. 네 번째, 전통과 현대 주거 공간의 6대 교육특성을 기준으로 주거공간에서의 “덕육(德育)”과 학습 성장 두 가지 측면을 비교하여 가정교육을 도출하고, 현대 주거공간 디자인에 접목 시킬 수 있는 새로운 니즈를 도출한다. 본 연구를 통해 얻은 결과는 가정교육 행위가 미래주거 공간의 디자인 및 발전에 영향을 끼친다는 것이다. 또한, 전통과 현대의 가정교육과 주거 공간의 연관성을 비교하여 주거문화와 가정교육을 융합한 주거공간에서의 교육행위 특성을 도출 및 아래 몇 가지 측면으로 정리할 수 있다. 공통점은 (1) 주거 공간 중 가정에서 “덕육(德育)”은 가정교육의 핵심이다. (2) 학습 성장은 가정교육의 주체이다. 위 두 가지로 정리 할 수 있고, 차이점은 전통 주거 공간에서의 교육 행위는 가정의 교육과 교육의 계승에 중점을 두는 반면, 현대 주거 공간에서의 교육 행위는 우수한 전통적 교육 문화 계승을 제외한다는 것에 있다. (1) 교육 역할의 갱신에 더 중점을 두고 있으며, 전통 방식의 수동적 교육행위에서 주동적 “활(活)교육”행위로 전환 되었다. (2) 탄력적인 교육공간의 확대. 주거 공간 내부의 사용은 평등하며, 명확한 공간의 경계가 없다. 또한 공공 공간이 확대되어, 자녀와 함께하며 자녀의 학습습관을 기르는 을 중시한다. (3) 정경체험(情景体验) 기능과의 융합. 현대 주거 공간은 디지털 기술 매체의 발전으로, 상황 시뮬레이션과 예술 체험 등의 보조 교육을 통해 아이들의 봉사 의식과 창의력을 키운다. 이 내용은 향후 미래 주거 공간에서의 가정교육 공간 디자인 갱신을 위한 기초와 근거로 제시될 수 있다. In this thesis, the author takes the educational attribute of Chinese residential culture as the basic research object and integrates the ideology, aesthetic appreciation and symbolization of residence space’s “XIANG” (Intangible Factor) culture and the space expression and decoration factors of “XING” (Tangible Factor) to reflect the relevance between residence space’s characters and family education, which are taken as the analysis standard. Moreover, the author makes a comparative analysis on educational behavior characteristic of Chinese traditional spacing residence space (represented by three-tier courtyard house in the period of Ming and Qing Dynasty) and modern residence space(suite residence in the late 20C). The author also emphasizes education’s importance in residence space design and highlights the correlation between “moral” education and learning growth, the differences of educational roles, educational spaces and scene experience characteristics, thus providing a basis for the design of family education space in the future residence. Firstly, from the perspective of integration between Chinese residential culture and family education, the author starts to make analysis from residence space’s “XIANG” (Intangible Factor) culture and “XING” (Tangible Factor) culture so as to discuss and analyze the correlation between residence space and educational characteristics on the cultural background from the five aspects: ideology, aesthetic appreciation, symbolization and space expression. Secondly, based on educational attribute of traditional residence space and modern residence space, the author makes an analysis on the standard of “XIANG” culture’s ancestral worship, respect for hierarchy and order, differences between man and woman, face south, learning from nature, clear distinction between the primary and the secondary as well as “XING” culture’s five factors: centrality, directionality, inside and outside of residence space, rooms of residence interior space and pattern design. Thirdly, through the process mentioned above, the author specifically makes a comparative analysis on the educational characteristics of traditional and modern residence space, thus leading out the uniformity and differences between traditional residence space’s family traditions and rules, learning rules for growth, moral value and modern residence space’s family culture, learning growth and social value. Fourthly, on the basis of six major educational characteristics of traditional and modern residence, the author makes a comparison, thus getting family education’s importance in residence space’s “moral education” and learning growth. Moreover, new requirements for modern residence space design are proposed. From this research, the author gets a consequence that family’s educational behaviors have an influence on the design and development of future residence space. In contrast with traditional and modern family education’s relevance with residence space, the author gets that the educational behavior characteristics of residence space with the integration of residential culture and family education are mainly presented as the following aspects: the similarities are: (1) Family’s “moral education” in residence space is the core of family education. (2) Learning growth is the main part of family education; The different points are: Traditional residence space’s educational behaviors place emphasis on the inheritance of education for home teaching rules; while in modern residence space’s educational behaviors, besides inheriting traditional educational culture, (1) The update of educational role is paid more attention. The educational behavior of traditional passive teaching is changed into positive “living education” behavior. (2) The flexible educational space is enlarged. Residence space’s internal use is equal without specific space limit; public space is expanded and the interactive behaviors and learning habit of parent-offs

Efficacy of the predator Mallada basalis (Neuroptera: Chrysopidae) on Tetranychus kanzawai and Panonychus citri (Acari: Tetranychidae) at different predator:prey release ratios

Ling Lan Cheng,James R. Nechols,David C. Margolies,James F. Campbell,Ping Shih Yang,Chien Chung Chen,Chiu Tung Lu 한국응용곤충학회 2012 Journal of Asia-Pacific Entomology Vol.15 No.1

Wecompared population suppression of the phytophagous mites, Tetranychus kanzawai Kishida and Panonychus citri (McGregor), on papaya by second instar larvae of the green lacewing, Mallada basalis (Walker), at various predator:prey release ratios in the laboratory. Initially, we presented M. basalis with mixed age classes of each mite species separately at a density of approximately 30 mites per seedling. After 3 days, predator:prey ratios of 1:30, 1:15, and 1:10 resulted in reductions of T. kanzawai of 66.8%, 82.6%, and 83.3%, respectively, and reductions of P. citri of 41.8%, 75.5%, and 77.2%, respectively. Predation on individual age classes was approximately equal in both species, reinforcing previous findings that this predator does not show a preference among age classes. We next presented M. basalis with mixed populations of the two mite species in which there were equal numbers of each species and the density was as in the single species tests. Total mite reduction with both mite species present was 48.5%, 71.9%, and 74.5% at ratios of 1:30, 1:15, and 1:10, respectively; T. kanzawai was reduced by 50.5%, 77.4%, and 79.5%, respectively, and P. citriwas reduced by 44.1%, 60.3%, and 63.2%, respectively. This study suggests that M. basalis has the potential for substantially suppressing populations of both T. kanzawai and P. citri on papaya at a predator:prey ratio of 1:15 or greater. However, evaluation under realistic agricultural settings is needed before specific recommendations about predator release rates can be made.

Optimization of Nominal Mixing Ratio of Mg to B in Fabrication of Magnesium Diboride Bulk

Yun Zhang,Cheng Lu,Si Hai Zhou,Kookchae Chung,Wen Xian Li IEEE 2009 IEEE transactions on applied superconductivity Vol.19 No.3

<P>In this paper bulk magnesium diboride (Mg<SUB>x</SUB>B<SUB>2</SUB>) with x varying from 0.9 to 1.3 was prepared by solid state reaction. The Mg:B mixing ratio for ideal MgB<SUB>2</SUB> is 1:2. The samples were sintered at 800degC for 60 h. Quantitative X-ray diffraction (XRD) analysis was performed to obtain the lattice parameters, the microstrain, and the weight fraction of impurities using the Rietveld refinement method. It has been found that the fraction of pure MgB<SUB>2</SUB> phase increases from x = 0.9 to x = 1.1, and then decreases with further increases in x. Mg<SUB>1.1</SUB>B<SUB>2</SUB> exhibits the highest critical current density, J<SUB>c</SUB>, over other samples in both low fields and high fields. A direct correlation between J<SUB>c</SUB> and connectivity indicates that better connectivity, caused by smaller amounts of impurities, results in the best J<SUB>c</SUB> in Mg<SUB>1.1</SUB>B<SUB>2</SUB>.</P>

Single cell gap polymer-stabilized blue-phase transflective LCDs using internal nanowire grid polarizer

Hong-Qing Cui,Zhi-Cheng Ye,Wei Hu,XiaoWen Lin,T.C. Chung,Tean-Sen Jen,Yan-Qing Lu 한국정보디스플레이학회 2011 Journal of information display Vol.12 No.3

Optically isotropic liquid crystal (LC) mixture such as blue-phase LC and nanostructured LC composites exhibit the advantages of fast response time, high contrast ratio and wide-viewing angle due to the induced birefringence along the horizontal electric field. Utilizing this mixture, a novel single cell gap in-plane switching-type polymer-stabilized blue-phase transflective liquid crystal display by embedding the nanowire grid polarizer as a polarization-dependent reflective polarizer in the R region is proposed. This device can be used as a normal black mode without any quarter-wave plate or patterned in-cell phase retarder. Moreover, the transmittance is identical to the reflectance so that it will be suitable for single gamma driving. Detailed electro-optic performances, such as voltage-dependent light efficiency and viewing angle of the proposed device configuration, are investigated.
