New limits are presented on the cross section for weakly interacting massive particle (WIMP) nucleon scattering in KIMS $\mathrm{CsI}(\mathrm{T}\ensuremath{\ell})$ detector array at Yangyang Underground Laboratory. The exposure used these results is $24\text{ }524.3\text{ }\text{ }\mathrm{kg}\ifmmode\cdot\else\textperiodcentered\fi{}\mathrm{days}$. Nuclei recoiling from WIMP interactions identified by a pulse shape discrimination method. A low energy background due to alpha emitters crystal...
The Reactor Experiment for Neutrino Oscillation (RENO) has been taking electron antineutrino ($\overline{\nu}_{e}$) data from the reactors in Yonggwang, Korea, using two identical detectors since August 2011. Using roughly 500 live days of through January 2013 we observe 290,775 (31,514) reactor $\overline{\nu}_{e}$ candidate events with 2.8 (4.9)% background near (far) detector. observed visible positron spectra both show discrepancy around 5 MeV regard to prediction current model. Based on...
Motion blur is a common photography artifact in dynamic environments that typically comes jointly with the other types of degradation. This paper reviews NTIRE 2021 Challenge on Image Deblurring. In this challenge report, we describe specifics and evaluation results from 2 competition tracks proposed solutions. While both aim to recover high-quality clean image blurry image, different artifacts are involved. track 1, images low resolution while compressed JPEG format. each competition, there...
Abstract This article analyzes structural changes in the information industries including publishing, broadcasting, film, cable, telephony, software and data processing, Internet era of "convergence" before after 1996. The cross-industry network structure was mapped using annual on mergers acquisitions among industry firms obtained from Journal Mergers Acquisitions. A comparative analysis these ownership transactions indicated that consolidating 1996 affected by both deregulation...
The Korea Invisible Mass Search (KIMS) Collaboration has been carrying out WIMP search experiment with CsI(Tℓ) crystal detectors at the YangYang Underground Laboratory. A successful reduction of internal background was done and a good pulse shape discrimination achieved. We report first result on obtained 237 kg days data using one full-size 6.6 mass.
Whole device printing is presented for realizing full colour displays with red (R), green (G) and blue (B) organic light emitting diodes (OLEDs). In this process, the whole OLED structure transferred from a patterned mould to glass substrate. Therefore, simple step repeat of transfer each R, G B RGB pixels completes fabrication display over given area. A difference in work adhesion at two interfaces enables transfer. 'rigiflex' used printing. It rigid enough allow sub-100 nm resolution yet...

소셜 네트워크 게임이란 서비스 플랫폼을 기반으로 하여 사용자 참여 및 관계 맺기를 활용한 사회적 인맥 기반 형태의 게임을 말한다. 본 연구는 HCI 분야에서 제시하는 가치모형을 중심으로 SNG의 지속적 사용의도에 영향을 주는 기능적, 유희적, 사회적, 개인적 가치 요인을 검토하였다. 분석 결과 유희적 가치와 기능적 가치가 것으로 나타났으며, 가치, 가치는 유의한 주지 않는 나타났다. 이는 서비스에 있어서 게임의 재미적 요인과 쉽고 편리한 인터페이스는 주요한 요소이지만, 이용자들의 사회관계적 동인은 큰 의미가 없음을 의미한다. Primarily working on SNS(Social Network Service) platform, the SNG(Social Game) utilizes friends and neighbors for invitation play. Based value model of HCI, this paper purports to discover how...
This study aims to investigate the effects of market commonality and resource similarity on price competition recursive consequences in Korean lodging market. Price comparison among hotels same geographic has been facilitated through development information technology, rendering little search cost consumers. While literature implies heterogeneous attack response hotels, a limited number empirical researches focus asymmetric pattern competitive dynamics. empirically examines interactions...
The results of a search for solar axions from the Korea Invisible Mass Search (KIMS) experiment at Yangyang Underground Laboratory are presented. Low-energy electron-recoil events would be produced by conversion into electrons via axio-electric effect in CsI(Tl) crystals. Using data an exposure 34,596 kg · days, we set 90 % confidence level upper limit on axion-electron coupling, g ae , 1.39 × 10 −11 axion mass less than 1 keV/c2. This is lower indirect neutrino bound, and fully excludes QCD...
이 연구는 인간성의 개념과 구성 요인들을 스마트 홈 맥락에서 대화형 에이전트에 적용하여, 의인화의 수준과 인터랙션 유형이 사용자 감성 경험과 향후 이용 의도에 미치는 효과를 알아보고자 하였다. 실험연구를 통한 분석 결과 고-저 인터랙션의 음성-채팅 유형은 친밀도, 호감도, 영향을 것으로 나타났다. 즉, 의인화 수준이 높고, 음성 인터랙션인 경우 에이전트를 더 친밀하고 호감이 가며 향후에도 계속해서 이용하고 싶은 대상으로 평가하였다. 또한, 관계없이, 채팅에 비해 인터랙션이 심리적 저항감이 낮았다. 대해서 유형의 상호작용 효과가 발견되었다. 채팅 인터랙션은 나타나지 않은 반면, 따라서, 스마트홈 에이전트는 수준을 높이는 방향으로 설계가 되어야 사용자들의 지속적 이용을 기대할 수 있다.

기존의 전자책 연구들이 이용과 충족 이론과 기술수용모형 중심으로 이루어졌던 반면, 본 논문은 전자책의 확산을 어렵게 만드는 원인을 혁신저항모형을 토대로 분석하였다. 따라서 연구에서는 혁신특성으로 상대적 이점, 적합성, 복잡성을, 사용자특성으로는 혁신에 대한 태도, 기존제품(종이책)에 태도를 변수로 도출하여 연구모형을 설정하였다. 온라인 설문조사를 실시해 각 변수들이 혁신저항에 미치는 영향을 알아보고 혁신저항과 수용의도의 관계를 검증하였다. 연구결과, 복잡성과 태도가 결정 요인이었고, 혁신저항은 수용의도에 부정적인 미쳤다. 구매에서부터 독서 경험 전 과정의 용이성을 높이는 데 주력해야 하며, 종이책의 사용경험과 차별화 되는 고유의 상호작용적 기능과 특성을 개발하고 부각해야 한다. While past studies on e-books have mainly focused the uses and gratifications (UG) technology acceptance...
