The purpose of this study is to develop an A-STEAM program using the Camera Obscura. The starting point of this study is the problems which students can encounter in real-life and it is designed to enable students to establish a research project. to integrate science, technology, engineering, and mathematics with main focus being art, and to explore all the avenues of expression using the Camera Obscura. In doing so, this study proposes possibilities of enhancement of students abilities to solve the problems and the development of artistic sensibilities. The process of developing the A-STEAM Program for art as a subject follows the PDIE process model by Jinsoo Kim. This study leaves the practice and evaluation as follow-up research and develops the teaching-learning process agenda, the paper for students' activities. and the materials for teachers' guidance by reflecting on the aspects of circumstantiation, creative design, and emotional touch. 본 논문의 목적은 카메라 옵스큐라를 이용한 미술중심 융합인재교육을 위한 수업자료의 개발에 있다. 이를 위하여 본 연구는 초둥학교 5, 6학년의 미술교과서 '관찰 표현' 단원을 재구성하고 학생자신이 실제 상황에서 부딪힐 수 있는 문제를 출발점으로 삼아 학생 스스로 과제를 설정하도록 하였다. 또한 카메라 옵스큐라를 이용한 표현 및 탐구 활동을 통해 미술 중심의 과학, 기술, 공학, 수학의 연계를 시도하였으며 시행착오를 거치는 가운데 탐구 활동을 통하여 학습자의 창의적 문제해결력과 예술적 감수성 발달의 가능성을 제시하였다. 수업자료 개발 과정은 김진수 (2012)의 초ㆍ중둥학교 STEAM 교육 수업자료 개발을 위한 PDIE 절차 모형을 따라 미술 교과용 A-STEAM 수업자료를 개발하였으며, 실행과 평가 단계는 후속 연구로 계획하고 각 차시별로 STEAM 학습 준거인 상황 제시, 창의적 설계, 감성적 체험의 요소를 반영하여 교수ㆍ학습 과정안과 학생 활동지, 교사용 자료를 개발하였다.

Cellulose is an abundant biodegradable material in nature with excellent properties, but due to its poor processability, it has been widely studied for processing through modification. Cellulose acetate propionate (CAP) is a cellulose derivative in which the hydroxyl group of cellulose is replaced by acetyl and propionyl groups. CAP has several advantages, such as excellent solubility, structural stability, light and weather resistance, and good transparency. Porous nanofibers with excellent specific surface area, which can be applied in various fields, can be easily formed by the phase separation method using highly volatile solvents. High speed centrifugal spinning is a nano/micro fiber preparation method with advantages such as fast spinning and easy alignment control. In this study, a CAP/polybutylene succinate (PBS) spinning solution with chloroform as solvent was prepared to prepare porous microfibers and the fiber morphology was examined as a function of the disk rotation speed in an high speed centrifugal spinning device.

Kim, Mi Suk,Park, Dong Hyuk,Cho, Eun Hei,Kim, Kyoung Ho,Park, Q-Han,Song, Hugeun,Kim, Dae-Chul,Kim, Jeongyong,Joo, Jinsoo American Chemical Society 2009 ACS NANO Vol.3 No.6
<P>Complex nanoparticles (NPs) of poly(2-methoxy-5-(2'-ethylhexyloxy)-p-phenylene vinylene) (MEH-PPV) NP adsorbed with Au NPs (MEH-PPV/Au NPs) were fabricated through a reprecipitation method. The formation of MEH-PPV/Au NP complexes was confirmed through high-resolution transmission electron microscopy and Fourier transform infrared experiments. The laser confocal microscope photoluminescence (PL) efficiency of the complex MEH-PPV/Au single NP dramatically increased compared with that of the MEH-PPV single NP without Au NPs, which was directly confirmed through color charge-coupled device images. The enhanced PL efficiency of the MEH-PPV/Au NP complex might have originated from the energy transfer effect in a surface plasmon resonance coupling between a MEH-PPV NP and Au NPs. The strong local field enhancement due to nanogaps between Au NPs in the background of a light-emitting MEH-PPV NP might be another origin of the PL enhancement of the NP complex, as supported by finite difference time domain calculations. We also observed the blue shift of the PL peaks of the single MEH-PPV and MEH-PPV/Au NP, compared with the solution PL peaks of those NPs.</P>

Enhancing adult neurogenesis in the brain has been suggested as a potential therapeutic strategy for AD. We developed a screening platform, ATRIVIEW®, for molecules that activate neuronal differentiation of adult mouse NSCs. The most potent hit from an FDA-approved drug library was SNR1611 (trametinib), a selective MEK1/2 inhibitor. We found that trametinib increases the levels of P15INK4b and Neurog2, suggesting a mechanism by which MEK1/2 inhibition induces neuronal differentiation. Oral administration of trametinib increased adult neurogenesis in the dentate gyrus and subventricular zone of the 5XFAD AD mouse model. Surprisingly, we also found that trametinib enhanced adult neurogenesis in the cortex. Consequently, trametinib rescued AD pathologies such as neuronal loss and cognitive impairment in 5XFAD mice. Finally, trametinib induced neurogenic differentiation of NSCs derived from AD patient iPSCs, which suggests its potential therapeutic application. Altogether, we suggest that restoration of endogenous adult neurogenesis by trametinib may be a promising therapeutic approach to AD.

<P><B>Abstract</B></P> <P>The electrical performance of organic field-effect transistors (OFETs) depends on the quality of thin-film organic semiconductors, which is significantly affected by solution-processing conditions and additional processes. We investigated the effects of post-thermal annealing on the thin-film morphologies of liquid crystalline organic semiconductors on polyimide gate insulator surface and the FET performances of the films. The active material selected for the OFETs was 2-decyl-7-phenyl-[1]benzothieno[3,2<I>-b</I>][1]benzothiophene (Ph-BTBT-C<SUB>10</SUB>), which shows a highly ordered smectic E (SmE) mesophase and polycrystalline thin films feature very high mobility.

Uniform bilayer- or monolayer-structured polycrystalline thin films were obtained on polymer gate insulator after thermal annealing at a SmE (over 148°C) and SmA (over 213°C) liquid crystalline phase temperature, respectively.

The electrospinning technique is a revolutionary template-catalyst-free method that can generate 1D nanostructure with the tunability and the potential for the mass production. This approach received a great deal of attention due to its ability to give direct pathways for electrical current and has been utilized in various electronic applications. However, the delamination of inorganic electrospun film has prevented the intense utilization due to the thermal expansion/contraction during the calcination. In this study, we propose an electrical grounding method for transparent conducting oxide and electrospun nanowires to enhance the adhesion after the calcination. Then, we examined the potential of the technique on ZnO based dye-sensitized solar cells.

Background In 2018, the World Health Organization (WHO) guidelines for the treatment of isoniazid (H)-monoresistant (Hr) tuberculosis (TB) recommend a six-month four-drug regimen: rifampicin (R), ethambutol (E), pyrazinamide (Z) and levofloxacin. However, the WHO assessed its regimen to be of very low certainty. This cohort study assessed the impact of fluoroquinolone (Fq) on treatment of effectiveness among Hr-TB patients. Methods This was a retrospective cohort study of 356 Hr-TB patients in 2010-2018. Baseline regimens were classified into 2 groups based on the duration of Z uses; 6-month REZ (6REZ) and combination of 2-month REZ and 7-month RE (2REZ/7RE). Multivariable logistic regression was performed to assess association between Fq use and negative regimen-specific outcomes, which included death due to TB, treatment failure or disease recurrence. Results Of 365 enrolled patients, 256 (71.9%) were treated with 6REZ regimen and 116 (32.6%) with additional Fq use. There were 93 (38.8%) and 39 (33.6%) cases of negative regimen-specific outcomes in patients treated without and with Fq uses, respectively. In a univariable logistic regression model comparing with and without Fq uses, there was no difference in odds of negative regimen-specific outcomes (odds ratio [OR] = 0.80, 95% confidence interval [CI] = 0.50-1.27); however, compared to 2REZ/7RE regimen, 6REZ regimen was significantly associated with negative regimen-specific outcomes (OR = 2.15, 95% CI = 1.29-3.61). Results varied minimally in a multivariable model. Among patients with positive outcomes, the median overall treatment period was 274 days and additional Fq use did not reduce overall treatment period (273 days in regimen without Fq vs. 279 days in regimen with Fq, p=0.086). Conclusions We found that additional Fq use did not show more benefits for Hr-TB patients. However, 2REZ/7RE regimen was more efficacious than 6REZ regimen. The WHO’s Hr-TB recommendation needs to be carefully re-evaluated with further prospective studies.
