인류가 고대로부터 물려받은 읽기/쓰기 행위는 인류의 의사소통 체계이자 지식정보 전달 체계로서 역사 속에서 끊임없이 변화하는 사회문화적 현상이다. 특히 디지털적 읽기/쓰기로 개개인의 일상사에 의미와 가치가 부여되는 시대, 그야말로 혁명적으로 일상적 담론과 대화들이 증폭된 지금 본 연구자는 이 시대의 '디지털적' 읽기/쓰기 방식과 이에 따른 의사소통 수단을 바흐친의 '일상생활의 산문'을 중심으로 점검하고, 그러한 현상이 새로운 유형의 콘텐츠로 재창조된다는 것을 이야기하고자 한다. 과거 읽기/쓰기는 '기록'의 과정을 통해 '서사의 창조'라는 지점에서 신성성을 부여받아왔다. 그러나 이는 현대로 오면서 데이터 간의 '하이퍼텍스트 링크'를 통해 변모하고 있다. 텍스트와 하이퍼텍스트를 통한 읽기와 쓰기는 선형적 서사성의 결여로 비난 받아야 할 현상이 아니라 사회문화적 변화의 한 과정이며 결과로 재평가되어야 한다. 읽기와 쓰기 방식의 변화는 콘텐츠의 층위, 지위, 의미, 가치의 변화를 수반할 수 밖에 없으며, 이에 '디지텔링'이라는 개념을 제안하여, 디지털 콘텐츠에서의 읽기/쓰기 방식을 새로운 대중문화 현상으로 접근해야 함을 주장하는 바이다.

The digital logic systems(DLS) is classified into digital combinational logic systems(CDLS) and digital sequential logic systems(SDLS). This paper presents a method of constructing the digital sequential logic systems without feedback. Firstly we assign all elements in Finite Fields to P-valued digit codes using mathematical properties of Finine Fields. Also, we discuss the operarional properties of the building block T-gate that is used to realizing digital sequential logic systems over Finite Fields. Then we realize the digital sequential logic systems without feedback. This digital sequential logic systems without feedback is constructed ny following steps. Firstly, we assign the states in the state-transition diagram to state P-valued digit dodo, then we obtain the state function and predecessor table that is explaining the relationship between present state and previous states. Next, we obtained the next-state function and predecessor table. Finally, we realize the circuit using T-gate and decoder.

The purpose of this paper is to let people know that current digital transition in digital cinema industry world wide is inevitable and radical. The parties concerned in the domestic film industry have not paid attention to this digital wave yet, In this research, we investigated about current situation of digital cinema industry and proposed digital film mastering, transport, technology, and business related models in digital cinema. To increase productivity of making a movie, we searched areas needing standards, created quality managing program, and proposed organization systems to perform those plans.

The main purpose of the study is to determine the main aspects of the problem of socio-economic development in the conditions of the digital economy. The post-industrial era is characterized by the development of the electronic environment and the transition to an information civilization. In this regard, the developed countries of the world pay considerable attention to the development of the digital economy. However, there are a significant number of problems associated with this process. The country cannot be successful in the development of the digital economy in the absence of the necessary legal framework, an economic development strategy based on digital technologies. The research methodology involves the use of several theoretical methods for analyzing and synthesizing information. As a result of the study, the key problems of socio-economic development in the digital economy were characterized.

We extended a general attack tree to apply cyber attack model for network vulnerability analysis. We defined an extended cyber attack tree (E-CAT) which extends the general attack tree by associating each node of the tree with a transition of attack that could have contributed to the cyber attack. The E-CAT resolved the limitation that a general attack tree can not express complex and sophisticate attacks. Firstly, the Boolean expression can simply express attack scenario with symbols and codes. Secondary, An Attack Generation Probability is used to select attack method in an attack tree. A CONDITION-composition can express new and modified attack transition which a aeneral attack tree can not express. The E-CAT is possible to have attack's flexibility and improve attack success rate when it is applied to cyber attack model.

The purpose of this study was to analyze the transition on architectural data such as valid indoor length, module, ratio of core, floor height, ceiling height and the type of structured cabling system according to the intelligent building grade through case study of the intelligent office buildings constructed in Korea since 1980. The results of this study were as follows. The average floor height was 3.80m, and it was higher in proportion to the IB grade. The average ceiling height was 2.57m, and it didn't have connection with the IB grade. The module of high frequency in application was $3.0{\times}3.0m$, and it showed 25% in the application frequency. The average valid indoor length was 12.27m. The average ratio of core was 24.49%. The type of high frequency in application for the structured cabling was Access Floor Type, and it showed 31% in the application frequency.

We developed a new cholesteric material for bistable LCDs. The material consists of dispersion of sub-micron ferroelectric particles in cholesteric host. We found that the doping of the cholesteric with ferroelectric particles in small concentration (< 1% by weight) strongly improved basic characteristics of the transition between poly-domain planar texture and focal conic texture. Decrease of the driving voltage, increase of the reflection contrast and the steepness of the transition is associated with giant steady dipole and dielectric constant of the ferroelectric particles.

This paper describes a CMOS data recovery circuit using oversampling technique. Digital oversampling is done using a delay locked loop circuit locked to multiple clock periods. The delay locked loop circuit generates the vernier delay resolution less than the gate delay of the delay chain. The transition and non-transition counting algorithm for 4x oversampling was implemented for data recovery and verified through FPGA. The chip has been fabricated with 0.6um CMOS technology and measured results are presented.

The core of the change in the era of the 4th industrial revolution is the change in the base of 'digital technology'. These changes are incomparably large and are expected to have a more important impact on our lives than ever before. One of the major inflection points in the transition to the digital era is the education field, and IT technology has become an essential element in the educational field. Accordingly, this study examines domestic research trends related to the educational environment based on digital technology. Then, we would like to provide implications for the establishment of a digital-based educational environment that will change in the future. To this end, Semantic network analysis has been conducted to quantitatively structure text data obtained from studies related to digital technology in the field of mathematics education over the past 10 years, and the discussion will continue based on the results.
