As a follow-up study of the study conducted by Kim Hye-ryeon (2016), As for dance teaching style preference measurement tool, First, results show that questions 25~30 of validity based on the contents of test are considered inappropriate. Second, validity evidence based on the reality turned out to be appropriate. Third, this study confirmed that validity based on the internal structure has a sufficient condition. Fourth, as for the validity based on the generalization, this study also confirmed through analysis of differential function that there are questions functioning differentially according to the grade (the lower grades, the higher grades) and major (Korean dance, ballet, modern dance).

유아교육에서 미적교육에 관한 이론적 고찰 : Schiller의 『미학 편지』를 중심으로
양혜련,임부연 부산대학교 영유아보육연구소 2007 영유아보육연구 Vol.13 No.-
There is a growing interest in the arts and aesthetic education as a critical alternative for reason-centered modem education. Schiller who had already forecasted the dark aspects of human reasoning in modern society, insisted paying more attention to the aesthetic education. In the book, 『The Aesthetic Education of Man』 which includes his speculation about beauty and the naturc of man, Schiller emphasized perfect coexistence and unification of sensuous drive and formal drive human mind. In terms of Schiller, Play drive that is a combination of sensuous and formal aspect can foresee completion of man, and it is only possible through beauty and aesthetic education by the arts. Schiller's aesthetic education gives suggestions to early childhood education that is abundant with the beauty, art, imagination, and play as those are also core part in Schiller's theory too. Especially, this article explored how beauty and arts are connected to the essence of early childhood education. Finally, this study also discussed educational implication of Schiller's aesthetic theory and direction of today's early childhood education that is asked more careful consideration about aesthetic appreciation and art education.

New vinyl derivatives of furan and pyrrole, such as (E)-4-methyl-1-(2-pyrryl) penten-3-one(6d),(E)-1-(2-furyl)-3-(p-ethylphenyl)propen-e- one(6b'),(E)-1-(2-furyl)-3-(p-chlorophenyl)propen-3-one(6c'), (E)-1-(2-furyl)-3-(p-methoxyphenyl)propen-3-one(6d'),(E)-1-(2-furyl)-3-(m-nitrophenyl)-propen-one(6e') and (E)-1-(1-methyl-2-pyrryl)buten-3-one(12a) were prepared by the condensation of furfural and 1-methyl-2-formylpyrrole with the corresponding compounds having active methylene group. The reduction of compound(6d) with NaBH₄gave only (E)-4-methyl-1-(2-furyl) penten-3-ol(9d). In the application of the Huang-Minlon modification under the same condition, the reduction of vinylpyrrole deribatives gave 1-(1-methy1-2-pyrryl) butane(13a)and 1-(1-methyl-2-pyrryl)-3-phenylpropane(13a'), but vinylfuran derivatives were not reduced to the corresponding alkyl derivatives of furan because of their easy polymerization at low temperature.

Substituent effects on the electron delocalizability of derivatives of vinylpyrrole and pyrrole imine have been examined in MeOH solution by ultraviolet spectrophotometry. The effects did not appear to be additive, but longer wavelength shift due to conjugation and electron withdrowing group. Specially, the significant difference in ?? for derivatives of pyrrole imine was seem to be caused by the conjugation effect and the position of the substituents.

본 연구에서 고투과도를 갖는 실리카 분리막은 콜로이달 실리카 졸과 고분자형 실리카 졸 두 가지를 DRFF법과SRFF법으로 다공성 금속 지지체 위에 코팅하여 제조되었다. 실리카 졸은 졸-겔법으로 테트라에톡시실란(TEOS)에 의하여 제조되었고, 각각의 졸은 동적광산란법(DLS), 전계방사 주사전자현미경(FE-SEM), 질소 흡착법 등을 이용하여 그 특성을 평가하였다. 다공성 금속 지지체위에 콜로이달 실리카 졸로 중간층을 형성하여 치밀한 구조의 실리카 층을 형성한 후 그 위에 분리층으로 고분자형 실리카 졸을 코팅하여 핀홀을 줄이는 방법으로 기체분리용 분리막을 제조하였다. FE-SEM으로 분리막의코팅 층을 분석한 결과 분리층은 중간층보다 침밀한 구조를 가지고 있음을 확인하였고 기체투과 결과 수소 투과도 (6.63-9.21) × 10-5 mol⋅m-2⋅s-1⋅Pa-1 분포를 보였다. Silica membranes with high permeability were prepared using colloidal and polymeric silica sols on a porous stainless steel-tube support by a DRFF and SRFF method. Silica sols were derived with tetraethylorthosilicate (TEOS) by sol-gel method and analyzed with DLS, FE-SEM, and N2 adsorption. The coating of the intermediate layer with colloidal silica sol on the stainless steel-tube support led to a denser surface morphology of the membrane along with a considerable reduction in the number of surface defect. As the polymeric silica sol enclosed the colloidal silica sol with spherical par-ticles during the SRFF method, the separation-layer-coated silica membrane showed a denser surface than the intermediate layer. Moreover, the silica membranes showed high hydrogen gas permeability of (6.63-9.21) × 10-5 mol⋅m-2⋅s-1⋅Pa-1 with low H2/N2 perm-selectivity (2.9-3.1) at room temperatures.

소셜미디어는 사회적 상호작용의 중요한 부분이 되고 있다. 소셜미디어가 심리적 안녕감에 미치는 영향을 이해하기 위해서는 소셜미디어를 이용하는 개인의 동기를 살펴보는 것이 중요하다. 개인들이 소셜미디어 이용에서 무엇을 추구하는지에 따라 이들의 소셜미디어 이용 정도 뿐만 아니라 그에 따른 심리적 결과 또한 달라질 수 있기 때문이다. 이에 본 연구는 미국(N= 564)과 한국(N= 565)의 대학생을 대상으로 한 설문조사를 통해 소셜미디어 이용동기와 심리적 안녕감 간의 관계를 탐색했다. 더불어 이러한 관계에서 문화적 차이가 나타나는지를 한국과 미국의 데이터를 비교하여 고찰했다. 연구결과, 소셜미디어 이용동기가 소셜미디어 이용(즉, 소셜미디어 사이트 이용 개수)에 미치는 영향은 동기의 종류에 따라 다르게 나타났다. 또한 소셜미디어는 두 가지 매개변인 - 사회적 지지와 자아 존중감 - 을 통해 심리적 안녕감에 영향을 미치는 것으로 나타났다. 이러한 관계의 양태는 미국과 한국에서 차이를 보여, 문화가 이 관계에서 중요한 영향력을 행사함을 제시한다. 이러한 결과가 제시하는 함의 또한 논의되고 있다. Social media has become an important part of social interaction. To understand how social media influences psychological well-being, it is important to examine the motivations behind how people use social media. What individuals seek to gain from social media may influence not only the nature and extent of their use of social media but also the type of psychological outcomes they obtain from it. The present study used survey data from the U.S. (N=564) and Korea (N=565) to investigate cross-cultural differences in the relationship between psychological well-being and six different motivations and outcomes of social media use. The study further investigated cross-cultural differences in the relationship between psychological well-being and social media use by comparing American and Korean college students. The results showed that different motivations exerted varying levels of influence on the number of social media sites used. Moreover, the number of social media sites used was shown to influence psychological well-being through two different outcomes: perceived social support and self-esteem. The pattern of the relationship also differed for the U.S. and Korea, thus demonstrating that culture exerts an influence on the observed relationship. The implications of these findings are discussed.

A glucose sensor electrode was prepared with multi-walled carbon nanotubes (MWNTs) because of its effect on surface modification through oxyfluorination. The oxyfluorination of MWNTs was carried out with F2:O2 ratios of 7:3, 5:5 and 3:7, which are labeled F7O3-MWNT, F5O5-MWNT, and F3O7-MWNT,based on the oxyfluorination conditions. The hydrophilic functional groups were introduced effectively on the hydrophobic carbon surface. In addition, the amorphous area of the MWNTs was affected by oxyfluorination. The reactivity of the glucose sensor was affected by the oxyfluorination treatment and the existence of amorphous on MWNTs. The optimum O/F percentage was approximately 50%. Therefore, the oxyfluorination conditions are important with amorphous MWNTs. The sensitivity was improved based on the effects of improved interface affinity between the enzyme and the carbon electrode. In addition, the presence of an amorphous area on MWNTs seems to be beneficial for efficient glucose oxidase immobilization, which results in high-performance glucose sensing.
