Over the past decade or so, dramatic developments in our ability to experimentally determine the content and function of genomes have taken place. In particular, next-generation sequencing technologies are now inspiring a new understanding of bacterial transcriptomes on a global scale. In bacterial cells, whole-transcriptome studies have not received attention, owing to the general view that bacterial genomes are simple. However, several recent RNA sequencing results are revealing unexpected levels of complexity in bacterial transcriptomes, indicating that the transcribed regions of genomes are much larger and complex than previously anticipated. In particular, these data show a wide array of small RNAs, antisense RNAs, and alternative transcripts. Here, we review how current transcriptomics are now revolutionizing our understanding of the complexity and regulation of bacterial transcriptomes.

Spinel thin films were prepared by the spin spray technique to develop new thermal imaging materials annealed at low temperature for uncooled microbolometer applications. The spinel thin films were deposited from $[(Ni_{0.30}Co_{0.33}Mn_{0.37})_{1-x}Cu_x]_3O_4$ ($0.1{\leq}x{\leq}0.2$) solutions and then annealed at $400^{\circ}C$ for 1 h in argon. Effects of Cu content (x) and deposition time on the electrical properties of the annealed films were investigated. With increasing deposition time, the resistivity of the annealed films increased. For the annealed films deposited for 1 min, the resistivity of x=0.15 films was lower than that of x=0.1 films due to the different grain sizes. The high temperature coefficient of resistance (TCR) of the annealed films could be obtained at temperature below $50^{\circ}C$. Typically, the resistivity of $127{\Omega}{\cdot}cm$ and TCR of -5.69%/K at $30^{\circ}C$ were obtained for x=0.1 films with deposition time of 1 min annealed at $400^{\circ}C$ for 1 h in argon.

최근 지속적으로 논의하고 있는 '지능정보사회'란? 지능정보기술을 기반으로 사회 전 영역에서 인간능력의 한계를 뛰어넘는 자동화가 보편화된 미래사회상을 의미한다. 특히, 인간의 개입을 최소화하고, 데이터(또는 빅데이터) 기반 완전 자동화로의 진화를 지속적으로 추구하는 개념이다. 예를 들어, 자율형자동화는 인공지능을 핵심요소로 무인자동차를 지속적으로 지향하고 있다. 그러나 지금까지의 지능정보 연구는 지능화 자체를 중심으로 지능화 논리를 고도화하여, 인간의 뇌와 지능을 대체하고자 하는 노력을 기울여 왔다. 또한, 다른 한편으로 인간의 노동력을 대체하기 위해서 노동자의 작업 원리를 분석하여 최적화된 단순논리를 개발하여 노동자를 로봇으로 대체하려는 노력을 지속해왔다. 본 연구는 지능정보기술 연구 전략 및 교육서비스에 관한 접근전략, 교육방법, 세부정책 로드맵 등을 제안하여, 지능정보 교육 정책 및 지능정보기술 연구 전략을 시행하는데 중요한 기준과 방향을 제시하고자 한다. 특히, 교육방법으로 기초지능교육, 지능콘텐츠교육, 지능응용교육 등의 지능정보교육의 단계적 접근 방안을 제시한다. 또한, 지능화 및 자동화가 중심이 되는 4차 산업혁명 성패를 가를 수 있는 중요한 요소로서 지능정보기술, 지능교육콘텐츠, 지능형 교육시스템 개선을 위한 교육정책 방안을 제안한다.

The knowledge-based society of the 21st century requires effective education and learning methods in each professional field because the development of human resource determines its competence more than any other factors. It is highly desirable to develop an intelligent tutoring system, which meets ever increasing demands of education and learning. Such a system should be adaptive to each individual learner's demands as well as the continuously changing state of the learning process, thus enabling the effective education. The development of a learning environment based on learner modeling is necessary in order to be adaptive to individual learning variants. An intelligent learning environment is being developed targeting the heritage education, which is able to provide a customized and refined learning guide by storing the content of interactions between the system and the learner, analyzing the correlations in learning situations, and inferring the learning preference from the learner's learning history. This paper proposes a heritage learning system of Bulguksa temple, integrating the ontology-based learner modeling and the learning preference which considers perception styles, input and processing methods, and understanding process of information.

Streaming Technology can support the real-time playback without downloading and storing multimedia data in local HDD. So, client browser or plug-in can represent multimedia data before the end of file transmission using streaming technology. Recently, the demand for efficient real-time playback and transmission of large amounts of multimedia data is growing rapidly. But most users' connections over network are not fast and stable enough to download large chunks of multimedia data. In this paper, we propose an intelligent IP streaming system based on personalized media service. The proposed IP streaming system enables users to get an intelligent recommendation of multimedia contents based on the user preference information stored on the streaming server or the home media server. The supposed intelligent IP streaming system consists of Server Metadata Agent, Pumping Server, Contents Storage Server, Client Metadata Agent and Streaming Player. And in order to implement the personalized media service, the user information, user preference information and client device information are managed under database concept. Moreover, users are assured of seamless access of streamed content event if they switch to another client device by implementing streaming system based on user identification and device information. We evaluate our approach with manufacturing home server system and simulation results.

Increase of aging population and demands for care and support systems, needs and demands for a variety of care services and housing facilities have increased. With the emergence of gerontechnology, tangible and intangible technologies and innovations have been explored and developed in many countries. Since housing environment is very important to define well-being and quality of life of the elderly, technology applications in the living environment are considered as important means. The purpose of this study is to enumerate and investigate technologies for the elderly to assist daily living and help care providers, and to explore technology applications in the built environments. This study also investigate how intelligent technologies are installed in the built environment and physical consideration for a variety of approaches. The content analysis was conducted to investigate technology developments for the elderly based on web materials and publication materials. The seven examples were chosen since they are seeking technologies especially for the elderly or aging-in place. General goals for the diffusion of intelligent homes expecially for the elderly are to be easy to install and remove, unobtrusive, redundant cueing, easy to use, and robust. The results of this study suggest application considerations for the technologies of the built environment for the elderly.

Ferroelectric SrBi2Ta2O9 (SBT) thin films of Pt/Ti/SiO2 electrode were fabricated using a sintered SBT target with various Bi2O3 content by rf magnetron sputtering. Good hysteresis loop characteristics were observed in the SBT thin films deposited with 50mol% excess Bi target. SBT thin films crystallized from 650℃ however, good hysteresis loop can be obtained in the film annealed above 700℃. pt/TiO2/SiO2 and Pt/SiO2 electrodes were also used to investigate the Pt electrode dependence of SBT thin films. SBT thin films showed random oriented polycrystalline structure and similar morphology regardless of electrodes with quite different surface morphology. A 0.2㎛ thick SBT film annealed at 750℃ exhibited the remanent polarization (2Pr) of μC/㎠ and coercive voltage(Vc) of 1V at an applied voltage of 5V.
