The English language textbook for classes XI-XII, currently in use nationwide in Bangladesh, has drawn numerous reactions from multiple corners of the country. Bangladeshi teachers, major stakeholders, have been noticeably concerned about the effectiveness of the design of the textbook based on their teaching experiences (Hani & Siddika, 2018). It is important to know their perceptions of the textbook, since their perceptions have a significant influence on students’ learning English through the textbook. The current study, therefore, seeks to provide information about the participant teachers and their teaching contexts in order to judge the value of the textbook design in terms of contents selection and organization. For that research purpose, interviews were conducted with 10 teachers who were, at the time of research, teaching the textbook at different colleges in a district of the country. Based on the data, the study discusses the teachers’ first-hand experience with the textbook, providing a revealing insight into how well it facilitates students’ learning in the classroom. Finally, implications are suggested that are expected to guide the design of the next applicable version of the textbook.

가석방은 수형자의 자발적인 개선을 유도함과 동시에 재범위험성이 없는 수형자를 조기에 사회에 복귀시키는 역할을 하지만 국민의 법감정 및 사회복귀 준비 정도 등 많은 요인에 의해 영향을 받는다. 우리나라의 가석방 제도는 1996년 개정된 이래 법 무부 가석방심사위원회에서 가석방심사를 하는 시스템으로 운영되고 있다. 하지만 가 석방 심사 제도는 그동안 많은 비판에 직면해 왔다. 본 논문의 주요 목적은 그동안 제기된 가석방과 관련한 쟁점에 대한 비판적 검토를 통해 현재 운영되고 있는 가석방 제도의 실질적인 문제점과 향후 발전방향을 모색하는 것이다. 그간 제기된 가석방 제 도와 관련한 주요 비판은 가석방 제도의 소극적 운영, 가석방 심사기준의 모호성, 가 석방심사 신청기관의 재량권 통제 장치 미흡, 가석방심사위원회 심사의 형식화에 대 한 우려로 나누어 볼 수 있었다. 하지만 이에 대한 비판적 검토를 통해 기존의 이러한 비판에 대응하여 법무부 교정본부 및 법무부 가석방심사위원회에서는 최근에 가석방 을 보다 확대하고 재범예측지표를 개발하는 등 많은 개선을 이루었음을 알 수 있었다. 그리고 주된 비판 중의 하나였던 법무부 가석방심사위원회에 의한 가석방 심사는 1996년 이전 각 기관 신청 방식의 문제점을 해결하기 위해 도입된 것이며 처음 도입 취지에 맞게 전국적으로 일관된 기준에 따라 가석방 심사가 이루어 질 수 있는 효율적인 제도라고 판단된다. 하지만 향후 가석방 제도 운영의 효율화를 위해 성인과 소년수형자 가석방의 일원화, 법무부 가석방심사위원회 확대, 가석방 요건으로 수용생활 태도 등의 비중 강화, 가석방 조건의 다양화와 사회적 처우 프로그램과의 연계, 가석방 기준 완화에 따른 재범률 증가에 대한 국민의 인식전환이 필요하다.

The crystallization effects of boron (B) powder on the phase, full width at half maximum (FWHM) values, and critical properties were investigated for in-situ reacted MgB2 bulk superconductors. The semi-crystalline B powder was heat-treated at different temperatures of 1000, 1300 and 1500˚C for 5 hours in an Ar atmosphere. Then, using as-received and heat-treated B powders, the MgB2 samples were prepared at 600˚C for 40 hours in an Ar atmosphere. As the heat-treatment temperature of the B powder increased, both the particle size of the B powder and crystalline phase increased. In the case of MgB2 samples using B powders heat-treated at above 1300˚C, unreacted magnesium (Mg) and B remained due to the improved crystallinity of the B powder. As the heat-treatment temperature of B powder increased, the critical current density of MgB2 decreased continuously due to the reduction of grain boundary density and superconducting volume caused by unreacted Mg and B.

Five kinds of double stacked 385 (55 x7) filamentary Bi2212/Ag round wires and 55 filamentary tapes with different Ag ratios (silver area/superconductor area) have been fabricated via PIT method, and the effects of Ag ratio and processing factors on critical current density were studied. The effects of the maximum temperature and average filament diameter on critical current density were also studied. The wire of 0.74 mm diameter having Ag ratio 3.7 showed critical current density of at 4.2 K, 0 T.

This paper investigates key discursive practices constructed in English language teaching (ELT) in Korea and calls for the necessity of ‘criticality’ in theorizing, researching, and pedagogical practices. Utilizing a new qualitative research orientation of ‘bricolage’ (Denzin & Lincoln, 2005; Kincheloe, 2004) and critical discourse analysis (CDA; Fairclough, 1995), this paper engages in multi-methods of collecting, analyzing, and interpreting the data. More specifically, some current issues related to ELT in Korea are juxtaposed critically with various historical, political, sociocultural, and economical factors. This is to investigate how these factors influence the formation of discursive practices regarding the NS-NNS dichotomy and ownership of English, teaching English for practicality, relationships between language, culture, and power, and neutralizing and depoliticizing key concepts in ELT. This paper suggests that ELT in Korea is a site in which multiple discourses are contesting to delineate particular ways of teaching and learning. Accordingly, this paper argues that ELT practitioners should be aware of the role of English as symbolic power and understand what is implicated in current discursive practices in ELT in order to possibly engage in more progressive pedagogy in line with Freirian consciousness-raising or problematizing practices for Korean learners of English.

We fabricated YBCO film using a TFA-MOD method. In order to enhance the reaction kinetics and to control the formation of the second phases, and powders were used as precursors (the so called "211 process"). The films were calcined at and then fired at in a 12.1% humidified atmosphere. We found that the microstructure varied significantly with the firing temperature. The textures of all of the films were similar and mainly biaxial. For the film fired at , the critical current was obtained to be 39 A/cm-width (corresponding critical current density is 2.0 MA/).
