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.

<P><B>Abstract</B></P><P>LiFePO<SUB>4</SUB> nanoparticles were grown on nano-graphite platelet (NGP) using a simple chemical route. The material was used as the cathode in Li-ion rechargeable batteries and exhibited excellent cyclability and rate capability because of the easy electron transport in it. The electrochemical stability of the electrode was improved by the two-dimensional conductive network of the NGP. The resulting electrodes delivered a specific capacity of about 150mAhg<SUP>−1</SUP> at a current rate of 135mAg<SUP>−1</SUP> (∼0.8C) after 100 cycles with no capacity fade. At elevated current rates, the electrodes exhibited capacities of more than 100mAhg<SUP>−1</SUP> at a current density of 2000mAg<SUP>−1</SUP> (∼12C) without further incorporation of conductivity agents or coatings.</P>

The drug repurposing strategy has been applied to the development of emergency COVID-19 therapeutic medicines. Current drug repurposing approaches have been directed against RNA polymerases and viral proteases. Recently, we found that the inhibition of the interaction between the SARS-CoV-2 structural nucleocapsid (N) and spike (S) proteins decreased viral replication. In this study, drug repurposing candidates were screened by in silico molecular docking simulation with the SARS-CoV-2 structural N protein. In the ChEMBL database, 1994 FDA-approved drugs were selected for the in silico virtual screening against the N terminal domain (NTD) of the SARS-CoV-2 N protein. The tyrosine 109 residue in the NTD of the N protein was used as the center of the ligand binding grid for the docking simulation. In plaque forming assays performed with SARS-CoV-2 infected Vero E6 cells, atovaquone, abiraterone acetate, and digoxin exhibited a tendency to reduce the size of the viral plagues without affecting the plaque numbers. Abiraterone acetate significantly decreased the accumulation of viral particles in the cell culture supernatants in a concentration-dependent manner. In addition, abiraterone acetate significantly decreased the production of N protein and S protein in the SARS-CoV-2-infected Vero E6 cells. In conclusion, abiraterone acetate has therapeutic potential to inhibit the viral replication of SARS-CoV-2.

<P>We aimed to identify prognostic factors associated with progression-free survival (PFS) and overall survival (OS) in metastatic renal cell carcinoma (mRCC) patients treated with sorafenib. We investigated 177 patients, including 116 who received sorafenib as first-line therapy, using the Cox regression model. During a median follow-up period of 19.2 months, the PFS and OS were 6.4 and 32.6 months among all patients and 7.4 months and undetermined for first-line sorafenib-treated patients, respectively. Clinical T3-4 stage (hazard ratio [HR] 2.56) and a primary tumor size >7 cm (HR 0.34) were significant prognostic factors for PFS among all patients, as were tumor size >7 cm (HR 0.12), collecting system invasion (HR 5.67), and tumor necrosis (HR 4.11) for OS (<I>p</I> < 0.05). In first-line sorafenib-treated patients, ≥4 metastatic lesions (HR 28.57), clinical T3-4 stage (HR 4.34), collecting system invasion (univariate analysis HR 2.11; multivariate analysis HR 0.07), lymphovascular invasion (HR 13.35), and tumor necrosis (HR 6.69) were significant prognosticators of PFS, as were bone metastasis (HR 5.49) and clinical T3-4 stages (HR 4.1) for OS (<I>p</I> < 0.05). Our study thus identified a number of primary tumor-related characteristics as important prognostic factors in sorafenib-treated mRCC patients.</P>

Objective: This study aims to investigate a relationship between a neural correlate of mental workload and the performance of the N-back memory task. Background: Many studies have explored neuronal correlates of mental workload by measuring the brain signal. In particular, the power of the theta rhythm (4-8 Hz) embedded in electroencephalogram (EEG) over the frontal region of the human brain has been shown to vary with mental workload. Studies have shown correlations between the frontal theta power and mental workload via various mental tasks, including the N-back task, Sternberg’s task, the multi-attribute task battery, mental arithmetic tasks and driving tasks, to name a few. However, behavioral evidence regarding the correlation between frontal theta power in individuals and their behavioral mental task performances still remains unclear. Method: Ten healthy subjects performed the N-back task with various task difficulties (0-3 back tasks), while their EEG signals were recorded using a 20-channel system. The power spectrum of the theta band (4-8 Hz) from bandpass-filtered EEG signals at the frontal channel (Fz) was calculated for each task. Results: The frontal theta power exhibited significant positive linear correlations with the error rates both in the 2-back and 3-back tasks (r > 0.68, F-test, p < 0.05), but neither in the 0-back task nor in the 1-back task. Conclusion: Individuals with poor N-back task performance showed greater frontal theta power, reflecting heavier mental workloads than those with good performance. The results indicate that one may use the frontal theta power of EEG to index individuals’ mental capacity in performing a given task.

<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.
