일본 학습장애아교육의 동향 : 일본 문부과학성 정책문서 분석을 중심으로

홍정숙 한국학습장애학회 2005 학습장애연구 Vol.2 No.2

본 연구는 문부과학성 정책문서의 분석을 통해 일본의 학습장애아교육에 대한 논의와 동향에 대해 파악하고자 하였다. 일본에서는 1990년을 기점으로 학습장애와 그 교육에 대한 논의가 공식적으로 이루어지기 시작하였다. 현재 일본은 특수교육으로부터 특별지원교육으로의 전환기에 있으며 이는 학습장애아교육과 밀접하게 관련되고 있다. 기존의 특수교육 대상에 더해 학습장애, 주의력결핍과잉행동장애, 고기능 자폐증의 아동을 새로운 교육지원의 대상으로 확대한 점이 특별지원교육의 중요한 골자이기 때문이다. 현재 일본에서는 학습장애에 대한 교육지원체제의 정비를 위한 모델사업이 문부과학성 주도하에 전국적으로 실시되고 있다.

Influence of clay particles on microfluidic-based preparation of hydrogel composite microsphere

홍정숙 한국유변학회 2016 Korea-Australia rheology journal Vol.28 No.2

For the successful fabrication of a hydrogel composite microsphere, this study aimed to investigate the influence of clay particles on microsphere formation in a microfluidic device which has flow focusing and a 4.5:1 contraction channel. A poly alginic acid solution (2.0 wt.%) with clay particles was used as the dispersed phase to generate drops in an oil medium, which then merged with drops of a CaCl2 solution for gelation. Drop generations were observed with different flow rates and particles types. When the flow rate increased, drop generation was enhanced and drop size decreased by the build-up of more favorable hydrodynamic flow conditions to detach the droplets. The addition of a small amount of particles insignificantly changed the drop generation behavior even though it reduced interfacial tension and increased the viscosity of the solution. Instead, clays particles significantly affected hydro-gelation depending on the hydrophobicity of particles, which produced further heterogeneity in the shape and size of microsphere.

홍정숙,표윤희,옥민욱 한국특수교육학회 2023 특수교육학연구 Vol.58 No.3

본 연구의 목적은 장애학생 교육권 보장과 통합교육 지원을 위한 정당한 편의 제공 지표를 개발하는 것이다. 현재까지 교육 분야에서 정당한 편의 제공을 위한 기준과 지침 마련은 부재한 상황이었다. 이에 본 연구는 정당한 편의 관련 문헌연구와 전문가 20명을 대상으로 델파이 조사를 실시하여 정당한 편의 제공의 지표를 개발하였다. 델파이 조사지 문항은 문헌분석 및 예비문항 작성과 전문가 협의로 추출되었다. 1차와 2차 델파이 조사 결과 정당한 편의의 지표가 5가지 하위영역(지원체제, 적절한 교육 및 평가, 인적 지원, 학습보조기기 및 보조공학기기・보조견 지원, 시설・설비)의 51개 지표로 최종 개발되었다. 이 지표는 통합교육환경에서 장애학생의 정당한 편의 제공을 위한 최소한의 기준과 지침으로 적용될 수 있다. 본 연구는 통합교육환경에서 장애학생이 의미 있는 교육을 보장받기 위한 정당한 편의 제공이 무엇인지 구체적 기준을 국내에서 처음으로 이끌어낸 의의가 있다. 국내 통합교육의 질 제고에 본 연구 결과가 기여할 수 있기를 기대한다.

Drop formation of Carbopol dispersions displaying yield stress, shear thinning and elastic properties in a flow-focusing microfluidic channel

홍정숙,Justin Cooper-White 한국유변학회 2009 Korea-Australia rheology journal Vol.21 No.4

The drop formation dynamics of a shear thinning, elastic, yield stress (τo) fluid (Carbopol 980 (poly(acrylic acid)) dispersions) in silicone oil has been investigated in a flow-focusing microfluidic channel. The rheological character of each solution investigated varied from Netwonian-like through to highly non-Newtonian and was varied by changing the degree of neutralization along the poly (acrylic acid) backbone. We have observed that the drop size of these non-Newtonian fluids (regardless of the degree of neutralisation) showed bimodal behaviour. At first we observed increases in drop size with increasing viscosity ratio (viscosity ratio=viscosity of dispersed phase (DP) / viscosity of continuous phase (CP)) at low flowrates of the continuous phases, and thereafter, decreasing drop sizes as the flow rate of the CP increases past a critical value. Only at the onset of pinching and during the high extensional deformation during pinch-off of a drop are any differences in the non-Newtonian characteristics of these fluids, that is extents of shear thinning,elasticity and yield stress (τo), apparent. Changes in these break-off dynamics resulted in the observed differences in the number and size distribution of secondary drops during pinch-off for both fluid classes, Newtonian-like and non-Newtonian fluids. In the case of the Newtonian-like drops, a secondary drop was generated by the onset of necking and breakup at both ends of the filament, akin to end-pinching behavior. This pinch-off behavior was observed to be unaffected by changes in viscosity ratio, over the range explored. Meanwhile, in the case of the non-Newtonian solutions, discrete differences in behaviour were observed, believed to be attributable to each of the non-Newtonian properties of shear thinning, elasticity and yield stress. The presence of a yield stress (τo), when coupled with slow flow rates or low viscosities of the CP, reduced the drop size compared to the Newtonian-like Carbopol dispersions of much lower viscosity. The presence of shear thinning resulted in a rapid necking event post onset, a decrease in primary droplet size and, in some cases, an increase in the rate of drop production. The presence of elasticity during the extensional flow imposed by the necking event allowed for the extended maintenance of the filament, as observed previously for dilute solutions of linear polymers during drop break-up.

17세기 네덜란드의 茶무역이 영국문화에 미친 영향

홍정숙 한국차학회 2011 한국차학회지 Vol.17 No.4

Tea culture begun in the East began to be introduced to Europe through trades with Netherlands in the 17th century. As culture of the 17th century has formed a lot of networks with maritime expansion, ruling by imperialists was the chance to introduce tea into the West with spices exploited from the colony, silk, jewel and precious metals from several regions of Asia including India through the Age of Discovery. Therefore, this study is to examine the process from the influx of tea to its settlement as taste beverage for Europeans through maritime expansion in Portugal,Espana and Netherlands, explorers' activities and their literatures.

Sedimentation and Rheological Study of Microalgal Cell (Chlorella sp. HS2) Suspension

홍정숙,신원식,남효린,윤진호,김희식,안경현 한국생물공학회 2022 Biotechnology and Bioprocess Engineering Vol.27 No.3

Microalgae (Chlorella sp. HS2) have a high potential as a new biomass filler resource. Microalgae suspension is investigated depending on pH condition, focusing on microscopic sedimentation and a rheological behavior in order to understand in-depth the behavior of Chlorella sp. HS2 for harvesting process design. In terms of sedimentation analysis, it is found that Chlorella sp. HS2 cells settle down due to high density of 1.56 gcm-3. Meanwhile due to its small size and dilute concentration, the settling velocity is too slow for harvesting by natural sedimentation. Chlorella sp. HS2 cells undergo weak aggregation in the medium depending on pH condition. When the Chlorella sp. HS2 suspension (pH 5.4) is adjusted at pH 2.5, the surfaces of the microalgal cells turn neutral and cells are aggregated by van der Waals force between cells, leading to relatively faster sedimentation compared to Chlorella sp. HS2 cells without pH adjustment. The aggregation of Chlorella sp. HS2 cells depending on pH condition is reflected in rheological properties of the suspension. At pH 2.5, shear viscosity of the Chlorella sp. HS2 suspension increases and the suspension shows shear thinning behavior, meaning that the neutralized surface of Chlorella sp. HS2 makes cells aggregation. However, the aggregation of microalgal HS2 cells is easily dissociated and aligned along shear flow. Therefore, for the successful harvesting of biomass Chlorella sp. HS2, the flow and colloidal condition must be considered along with coagulation for rapid harvesting of cells.
