This study aims to understand Korean students’ motivations for studying in US graduate schools. For this purpose, I conducted in‐depth interviews with 50 Korean graduate students who were enrolled in a research‐centered US university at the time of the interview. In these interviews, I sought to understand how their motivations are connected not only with their family, school, and occupational backgrounds, but also with the stratification of global higher education. Theoretically, this paper att

Uranium–organic framework solids, in which uranium building units are connected by bidentate dicarboxylate anions such as succinate, glutarate, and isophthalate, were synthesized; the glutarate and isophthalate compounds contain cavities, in which occluded water and organic templates reside.

The thermal conductivity of layered metal chalcogenides such as <TEX>$MT_2$</TEX> (M = Mo, W; T = S, Se) shows a marked decrease after exfoliation and subsequent restacking process. Random stacking of two-dimensional crystalline sheets circumvents thermal conduction pathways along a longitudinal direction, which results in a reduction in thermal conductivity. <TEX>$WS_2$</TEX> and <TEX>$WSe_2$</TEX> compounds retain p-type conducting behavior after exfoliation and restacking with decreased elect

We believe [(Th2F5)(NC7H5O4)2(H2O)][NO3] is the first three-dimensionally connected, actinide-organic framework solid. The structure is composed of thorium oxyfluoride chains, each of which connected to pyridinedicarboxylate groups to give a 3D cross-linked network with cavities containing nitrate anions.

This study analyzes the learning and cultural experiences of Korean graduate students in the United States. Based on 50 qualitative interviews, the study focuses on how global knowledge and the power relations of language determine their education in a transnational system. At a theoretical level, the study criticizes both the functionalist approaches that limit analysis to socialization processes and the pragmatic analyses that seek to solve problems of adaptation. Rejecting these perspectives,

Macromolecular nanoplatelets of the ferroelectric oxide Bi4Ti3O12 were synthesized by exfoliation reaction for the first time. Formation of the exfoliated nanoplatelets was confirmed by atomic force microscopy (AFM) and high-resolution transmission electron microscopy (HRTEM).

Herein, we report on a scalable synthesis of Au nanodot (Au-ND)/Bi₂Te₃ nanotube (BT-NT) nanocomposites by the bottom-up synthesis of hybrid raw materials and subsequent spark plasma sintering, and their thermoelectric properties were systematically compared with those of Au-doped Bi₂Te₃ compounds.

Four new uranium isonicotinate framework solids were synthesized in the UO 2 (CH 3 CO 2 )·2H 2 O/HF/isonicotinic acid system under hydrothermal conditions. The isolated uranium isonicotinates span a range of dimensionalities from zero-dimensional UO 2 (C 5 H 5 NCO 2 )(CH 3 CO 2 ) 2 ( 1 ), one-dimensional [UO 2 F 2 ][C 5 H 5 NCO 2 ] ( 2 ) and [UO 2 F 3 ][C 5 H 6 NCO 2 ]·0.5H 2 O ( 3 ), and two-dimensional [UO 2 F 2 ] 2 [C 5 H 5 NCO 2 ]·H 2 O ( 4 ). Regions of phase stability were determined using

As a doctoral student at the University of Illinois, I have been studying the sociology of science technology. One of main themes in the field is how society and technoscience co-produce each other generating a new assemblage among heterogeneous factors and forces. In the field of sociology cyberspace is increasingly viewed as a locus in which social life and interaction achieve new meanings and patterns. For the past 20 years computer-mediated communication (CMC) researchers have tried to under

미국 유학은 교육, 직업, 사회적 위신과 관련하여 한국사회에서 첨예한 문제로 대두되고 있으나 이 주제에 대한 경험적인 연구는 드물다. 이 논문은 미국의 한 연구중심대학에서 석사와 박사 과정을 밟고 있는 한국 유학생 총 50명을 심층 면접하여, 왜 이들이 유학을 선택했으며 이러한 교육적 포부가 그들의 가족, 학력, 직업 배경과 어떻게 연결되는지를 분석한다. 심층 면접을 통한 이들의 유학 동기는 (1) 사회적 지위의 상승 수단 (2) 글로벌 학문의 중심에서 배움 추구 (3) 학벌차별, 성차별, 대학문화의 비민주성으로부터 탈출 (4) 코스모폴리탄 엘리트가 되고픈 욕망, 이렇게 네 가지로 분류된다. 이론적으로 필자는 부르디외의 문화자본론을 글로벌 영역으로 확장시켜 글로벌 문화자본의 개념을 제시한다. 여기서 필자는 미국 유학 현상을 글로벌 문화자본의 형성과 대학과 학계의 글로벌 위계 속에서 분석하는 동시에 이를 한국대학과 학문생산의 구조, 한국사회에서 학력과 사회지위구조, 그리고 학문수행에

Herein, we report on a scalable synthesis of surfactant-free Bi2Te2.7Se0.3 nanocrystals by chemical exfoliation and subsequent spark plasma sintering to fabricate nanostructured thermoelectric bulk materials. The exfoliated n-type Bi2Te2.7Se0.3 nanoplatelets were shown to transform into nanoscroll-type crystals (∼5 nm in diameter, ∼50 nm in length) by ultrasonication. The thermoelectric performance of the Bi2Te2.7Se0.3 nanocrystals was found to be recoverable by minimizing surface oxides by chem

이 논문은 2008년 미 쇠고기 수입으로 촉발된 촛불운동에서 정부의 논리에 반하는 대항지식이대항전문가들(oppositional experts)의 혼성적 연대를 통해 어떻게 구성되는지를 분석한다. 촛불사태에서 광우병에 대한 과학적 지식과 정책이 논란의 중요한 쟁점으로 떠올랐으며 이는 전문지식의 정치화로 이어졌다. 광우병 논쟁은 절대적 과학적 준거점의 상실 하에 발생하였으며실재주의/구성주의, 현재/미래, 과학적 합리성/사회적 합리성, 사실/가치가 뒤섞여서 진행되었다. 정부의 논리와 대항지식 간의 대결 과정에서 대항전문가들의 역할은 촛불운동을 구성하는중요한 힘으로 작동했으며 이들이 생산한 대항논리들은 촛불운동의 정당성을 제공하고 미 쇠고기 재협상을 위한 구체적인 논거로 작동했다. 이론적으로 이 논문은 지식사회학(좁게는 과학기술사회학)과 사회운동론을 결합시켜 전문지식의 정치화, 전문가-시민의 연대, 사회세계-자연세계의 잡종화, 과학기술의 불확실성과 같은 개념들을 건설적으로 수용한다. 경험적
