The Internet has made a huge impact on the way we, as humans, communicate. During the last decade a series of new communication mediums have emerged and communication protocols have come and gone. This puts new requirements on the development process and architecture of the communication platforms, operated by communities, in order to proactively ensure support for future communication protocols. Even further, additional requirements are added when the software itself will be maintained by a community. In this paper we explore the world of Open Source Software. We present our suggestions of usable design-principles and our process in developing a sustainable information system.

지금까지 전통음악분야의 현대적 구현은 민간 연주자들에 의하여 음악을 계승 발전시켜왔다. 특히 농악놀이에 현대적 해석을 가미한 사물놀이는 전통음악 현대화의 일등공신이다. 그러나 전통문화에 대한 공학적 분석은, 에밀레종의 맥놀이 분석, 징의 RIM깊이에 따른 음향의 변화 등 다양한 분야에서 이루어지고 있으나, 전통문화와 IT의 융합은 접근하는 사례가 전무한 실정이다. 본 논문에서는 전통음악을 현대화시킨 사물놀이를 사물놀이 고유의 풍모를 살린 전통인형과 함께 임베디드 시스템으로 제작하고, 사물놀이 연주가 수록된 정간보를 디지털악보로 변환하여 악보 내용을 바탕으로 사물놀이 인형들이 각각 사물놀이 악기를 연주하여 사물놀이 본연의 조화를 이룰 수 있는 시스템을 구현하였다.

The number of people using the information communication have being rapidly increased owing to promote a national information policy. The rate of teenager using the information communication are over 90 percent. We can communicate quickly and easily owing to the rapid increment of the information communication. But there are adverse effects because of the rapid increment of the information communication. Specially, teenagers have been quickly influenced by the adverse effects. We must consider a counterplan for the adverse effects. Therefore, in this paper, I will survey the present status of ethics education for information communication which have been taught in school and the actual condition using information communication of teenagers. And I will analyze the connection of them. In addition, I will propose the desirable direction of ethics education for information communication.

In recent years, future information and communication technology (ICT) has influenced and changed our lives. Without various ICT-based applications, we would have difficulty in securely storing, efficiently processing, and conveniently communicating information. In the future, ICT will play a very important role in the convergence of computing, communication, and all other computational sciences and application. ICT will also influence various fields including communication, science, engineering, industry, business, law, politics, culture, and medicine. In this paper, we investigate the latest algorithms, processes, and services in future fields.

This paper presents a 6 Gb/s 4-channel arrayed transimpedance amplifiers (TIA) with the gain control for 4-channel passive optical network in $0.13{\mu}m$ complementary metal oxide semiconductor (CMOS) technology. A regulated cascode input stage and inductive-series peaking are proposed in order to increase the bandwidth. Also, a variable gain control is implemented to provide flexibility to the overall system. The TIA has a maximum $98.1dB{\Omega}$ gain and an input current noise level of about 37.8 pA/Hz. The die area of the fabricated TIA is $1.9mm{\times}2.2mm$ for 4-channel. The power dissipation is 47.64 mW/1ch.

It has become topic continuously at MEMS or semiconductor process to form three-dimensional multilayer structure. In this paper, we devised the new polymer pattern method that has multilayer structure. This is method that uses different kind of polymeric material. Specially, polymers used in this study that we propose became all pattern by photolithography, prevented that process increases. Here, polymer that we use used polymer of epoxy order called "SU-8" and polymer of novolak resin called "AZ-1518". The result, "SU-8" was formed pattern to 3.5um thickness, and "AZ-1518" about pattern 3um thickness. Also, It was been 6um thickness at same pattern area.

This paper describes two methods to assess the output speech, quality of vocoders for telephone conferencing in digital mobile communication networks. The proposed methods are the sentence discrimiantion method and the modified degraded mean opinion score (MDMOS) test. We apply these two methods to Qualcomm code excited linear prediction (QCELP), vector sum excited linear prediction (VSELP) and regular pulse excited-long term predictin (RPE-LTD) voceders to evaluate which vocoding algorithm can process mixed voice signal from two speakers better for telephone conferencing. From the experiments we obtain that the VSELP vocoding algorithm reveals superior output speech quality to the other two.
