만화는 21세기 고부가가치 산업 혹은 문화산업의 첨병이라 부리우고 있다. 그렇지만 정작 만화가 어떤 커뮤니케이션 경로를 거쳐서 고객인 독자에게 전달되어지는지에 대한 연구는 거의 전무한 상태이다. 만화가 어떤 커뮤니케이션 경로를 거치는지 분석하고 이해함으로서 효과적이고 성공적인 커뮤니케이션 전략을 수립할 수 있을 것이다. (중략)

This paper is about design broadband impedance matching circuit for Coupler to improve power transfer efficiency in the power line communication (PLC) system. The Tchebycheff gain function algorithm is represented to design broadband matching circuit. A practical PLC Coupler impedance matching circuit is designed, and the characteristics for S11 and S21 of PLC coupler are enhanced comparing with unmatched one. This is done by maximizing the power transfer gain from modem to the load.

This paper represents design broadband impedance matching circuit for Coupler to improve power transfer efficiency in the broadband power line communication(BPLC) systems. The Butterworth gain function equalizer is used to design broadband matching circuit. A practical PLC Coupler impedance matching circuit is designed, and the characteristics for S11 and S21 of PLC Coupler are enhanced comparing with unmatched one. This is done by maximizing the power transfer gain from modem to the load.

In this paper, we propose the method to improve the performance of the antenna system that contains three bands, such as Lte3G, WLAN and Lte4G. This antenna has an advantage that can cover the three different frequency bands 2.1GHz, 2.4GHz and 2.6GHz through one antenna design. The design and simulations are done using CST Microwave Studio 2014 program. The antenna is designed by using the FR-4 (lossy) substrate with the dielectric constant of er=4.3 and dielectric loss tangent 0.025. The substrate dimensions are the following; Thickness[h] is 1.6mm, Length is 90mm, and Width is 40mm. The ground is designed by using the PEC material with h=0.035mm. The patch is designed by using the copper with h=0.035mm. In the near future, we will fabricate the antenna, which we have designed, and then apply this antenna to the mobile communication system. And we will test this mobile communication system for the diverse environments.

China's intangible cultural heritage at the national level amounts to more than 1,500 species, and it is also the country with the largest number of items on UNESCO's intangible cultural heritage list, so the intangible cultural heritage of the country and mankind is very much treasured and cared for. However, with the development of the times, many intangible cultural heritages are facing a dilemma due to the problem of a single form of communication. However, at the same time, the efficient and convenient way of information visualization provides innovative ideas and new opportunities for the visual communication of Chinese intangible cultural heritage. This paper examines the formal characteristics of infographic visual expression on the theoretical basis of books and related papers and analyzes the application cases and advantages of infographics in the communication of Chinese intangible cultural heritage in the context of the present era. It aims to explore a fast and novel visual presentation method for the communication of Chinese intangible cultural heritage through infographic design methods, to promote the inheritance and development of Chinese intangible cultural heritage in the new era.

COMS (Communication, Ocean and Meteorological Satellite) is a geostationary satellite and has been developing by KARI for communication, ocean observation and meteorological observation. Conventional thermal control design, using MLI (Multi Layer Insulation), OSR (Optical Solar Reflector), heater and heat pipe, is utilized. Ka-band components are installed on South wall, while other equipment for sensors are installed on the opposite side, North wall. High dissipating communication units are located on external (surface) heat pipe and are covered by internal insulation blankets to decouple them from the rest of the satellite. External satellite walls are covered by MLI or OSR for insulation from space and for rejection internal heat to space. The ocean and meteorological sensors are installed on optical benches on the top floor to decouple thermally from the satellite. Single solar array wing is adopted in order to secure clear field of view of radiant cooler of IR meteorological sensor. This paper presents principles of thermal control design for the COMS.

This study explored the literature review for intending to make contemporary furniture expressed as postmodern aesthetics accessible to the broadest possible public, particularly through an examination and realization of art and everyday life, using qualitative analysis about the related literature as the principal methodology. The postmodern furniture aesthetics of communication expressed through double-coding, which was seen by Charles Jencks as the defining element of Post-Modernism, is characterized by the use of ideas from the traditions of craft. Hence, I dealt with pre-Modern furniture and Modern-furniture aesthetics as the background of postmodern furniture called New design furniture. As a result, contemporary furniture called New design furniture represented the use of ornament, craftsmanship, or beauty from the traditions of craft, which was a main source for communication value in postmodern furniture aesthetics.

The purpose of this study was to investigate the effect of brainwriting instruction on students' experimental design and scientific communication ability in elementary science class. For this purpose, a brainwriting learning for science class was developed and applied. The objects of this study were the 4th graders of both an experimental class (24 students) and a comparative class (24 students) at the N elementary school located in Incheon city. The results of the study were as follows; First, as a result of examining the difference in the experimental design ability between experimental group and comparative group, the experimental group showed higher than the comparative group, it was statistically significant difference(p<.05). Second, a scientific communication ability of the experimental group after applying this program was higher, it was statistically significant differences (p<.05).

In this paper, we described a design and implementation of a sensor node for environmental monitoring. The main focus of design for sensor nodes is to isolate MCU for treating sensors from the RF module for considering various communication environment. The second is to make the interface between MCU and varity of sensor. In addition, we choose a narrow band communication module, cc1020, for the admittance of Korea government communication law. We also use a uC/OS-II as an operating system which is famous for 8bit MCUs. We showed that the communication performance is sufficient to use the communication module in a out-door environment through several experiments in that it is possible to transmit between 100m distance through experiments in a mountain.
