Using an exceptionally rich, standardised education assessment dataset comprising over 1800 primary schools and 31,000 grade six students from 10 francophone Western and Central African countries, this study analyses the relationship between teacher gender, student gender, and student achievement. Findings indicate that, for girls, being taught by a female teacher increases math and reading performance. For boys, however, teacher gender has no effect. Similar, but less strong effects are also fo

Urban decentralisation in the USA during the past five decades has created an automobile-dependent landscape characterised by low-densities, largely single-use zoning and disconnected street networks. Longer distances between dispersing destinations, resulting from urban decentralisation, negatively affects the mobility of socially disadvantaged groups, including women, minorities and lower-income populations. Furthermore, the urban poor and minorities in communities experiencing severe disinves

We examined butanol fermentation by Clostridium beijerinckii NCIMB 8052 using various hydrolyzates obtained from rice bran, which is one of the most abundant agricultural by-products in Korea and Japan. In order to increase the amount of fermentable sugars in the hydrolyzates of rice bran, various hydrolysis procedures were applied. Eight different hydrolyzates were prepared using rice bran (RB) and defatted rice bran (DRB) with enzyme or acid treatment or both. Each hydrolyzate was evaluated in

The purpose of this study is to investigate the removal of dimethyl disulfide (DMDS) in the olefin rich Fluid Catalytic Cracking (FCC) C4 hydrocarbon mixture with the ion-exchanged β-zeolite. Effects of Si/Al ratio, metal cations, and the ion exchange level on the removal efficiency have been accessed by performing the breakthrough experiment with a model C4 mixture of 20 ppm DMDS in 40% n -Butane/60%1-Butene. The metal ions used for the preparation of ion exchanged zeolite are Ag(I), Cu(II), Ni

Age-related hearing impairment (ARHI) is becoming a more significant issue as geriatric population increases. Sarcopenia in older people is known to have a diverse health problem in various circumstances in recent studies. We assessed whether the decrease in muscle mass is related to ARHI. We used the 2010 data of the Korea National Health and Nutrition Examination Survey (KNHANES) to examine the associations between sarcopenia and ARHI. A total number of participants was 1,622 including 746 mal

OBJECTIVE: To investigate how the visual complexity of head-up displays (HUDs) influence the allocation of driver's attention in two separate visual domains (near and far domains). BACKGROUND: The types and amount of information displayed on automobile HUDs have increased. With limited human attention capacity, increased visual complexity in the near domain may lead to interference in the effective processing of information in the far domain. METHOD: Near-domain and far-domain vision were separa

Photo cartoonization aims to convert photos of real-world scenes into cartoon-style images. Recently, generative adversarial network (GAN)-based methods for photo cartoonization have been proposed to generate pleasable cartoonized images. However, as these methods can transfer only learned cartoon styles to photos, they are limited in general-purpose applications where unlearned styles are often required. To address this limitation, an arbitrary style transfer (AST) method that transfers arbitra

다문화주의 관점에서의 고등학교 교과서 분석 연구 A Study on High School English Textbooks in Terms of Multiculturalism 이 지 은 Lee Ji Eun 국 문 요 약 외국어를 성공적으로 학습하기 위해서는 그 해당 언어의 문화적 요소를 습득하는 것이 필수적이다. 우리나라 제7차 교육과정에서도 외국어 교육에 있어서의 문화적 요소의 가르침을 강조하고 있다. 학생들은 교과서를 통해서 영어사용국가의 문화를 가장 많이 접하고 배우게 된다. 그렇기 때문에 영어 교과서에 실리는 텍스트의 내용과 등장인물의 특성은 학생들이 영어사용국가에 대한 문화를 형성하는 데 있어서 지대한 영향을 미친다고 말할 수 있다. 이러한 영어 교과서의 영향성을 고려하여, 현 영어사용국가들의 추세인 다문화주의 관점에서 우리나라 고등학교 영어 교과서 8종 총 96단원에 등장하는 500명의 인물들을 인종, 성별, 나이, 사회적 계급, 신체적 결함상태로 분석하였다.

We have reviewed 54 service industry related articles published in Korea from 2001 to 2003. Three different types of review methods such as descriptive analysis, theme focused analysis and service industry focused analysis were employed. In particular, theme focused analysis included 5 different categories: service quality and customer satisfaction, service and e-business, service and business strategy, service productivity and service process design. It was found that many researches are relate

We have found that the close proximity among aptamer conjugated gold nanoparticles due to aptamer-target-aptamer binding can occur and result in a color change on fabric pads. In this study, we used aptamer-conjugated gold nanoparticles as a colorimetric transducer and successfully performed in situ onfabric colorimetric detection of thrombin using aptamer-conjugated gold nanoparticles. Gold nanoparticles immobilized with two model aptamers, thrombin binding aptamer (TBA) 15 and TBA 29, respecti

Chemical force microscopy analyzes the interactions between various chemical/biochemical moieties in situ. In this work we examined force-distance curves and lateral force to measure the interaction between modified AFM tips and differently functionalized molecular monolayers. Especially for the measurements in gas phase, we investigated the effect of humidity on the analysis of force-distance curves and the images in lateral force mode. Flat chemical patterns composed of different functional gr

자기조절학습전략은 메타인지적, 인지적, 동기적, 행동적인 전략들을 자율적으로 선택하고 적용하여 학습자가 적극적이고 능동적으로 학습에 참여할 수 있도록 돕는 학습전략이다. 본 연구의 목적은 수학저널 쓰기학습에서 자기조절학습전략의 양상은 어떠한가를 살펴보기 위함에 있다. 수학저널은 총 13문항으로 자기조절학습전략의 하위요소별로 1~2문항씩 구성하였다. 연구의 결과 수학저널에서 메타인지전략은 학습 목표 설정, 문제해결전략탐구, 반성적 사고, 예를 들어 설명하기 등으로 표현되었다. 인지전략은 아이디어간의 구조 파악하기, 위계화하기, 핵심 내용 파악하기 등으로 표현되었다. 동기전략은 학습에 대한 만족감과 불안감, 차후 학습에 대한 자신감과 좌절감 등으로 표현되었다. 이는 수학저널 쓰기학습을 통하여 자기조절학습전략이 활용되고 있으며 효율적이고 성공적인 학습을 돕는다는 점에서 수학 교육학적인 시사점이 있다.
