This study analyzes the public lecture conducted by a university in Seoul and examined how a public lecture on the emergence of a new media environment could influence the actual field of engineering education. The current public lecture is changing away from past patterns which have been conducted on a daily, irregular and offline basis. Online lectures such as Mooc programs, as well as broadcast programs in the Internet media environment, are becoming increasingly popular with mainstream education. This study focuses on exploring how public lecture experiences of engineering professors have affected the improvement of learner centered education and their communication skills. It also examines how public lecture in the field can affect to enhance public understanding of engineering. The advent of a new media environment is likely to inject new vitality into a college lecture that seems to fall behind in the past. It is highly likely that the reliance on the teaching capabilities of professors become higher according to the emphasis on active learning environment. The genre of public lecture is expected to greatly helpful to expand future engineering education methodologies.

Globalization of the industry induces the internationalization of any given manufacturing company's supply chain. Development of e-Commerce and Information Technology (IT) changes the logistics structure, making logistics information systems essential. Web-based connectivity and supply chains based on new technologies are becoming essential in the logistics industry. Customers are driving the implementation of systems to ensure timely, thorough, and accurate information, often with immediate access; in response, the Internet has propagated tracking and tracing systems. Value-added services are the key to successful intermediary activities. The nationwide Integrated Logistics Information System (ILIS) aimed to utilize existing and future information infrastructure and knowledge bases to build an integrated logistics information network that would provide comprehensive logistics information services for shippers and carriers in order to improve the efficiency of both inventory and information flows in their supply chains. The ILIS, as one of the seven national information networks, has provided various services, particularly services related to import/export and clearance. Though a survey concerning logistics information services shows rather positive results, shippers and carriers still require better services and reductions in EDI prices. Therefore, the role of the ILIS needs to be re-defined. Short-term plans for the ILIS contain ICD services and XML/EDI services, which are described in detail.

By the early 20 century, "workman" introduced by SONY was the leading portable analog sounder. However, at the same century, workman was pushed out from the portable sounder by iRiver developed by MPMAN.COM. This portable digital sounder is called MP3-Player (MP3P), and has become the most popular portable digital sounder in the current market. This study combined two customer satisfaction models, mobile internet customer satisfaction model (Yu, 2002), and portable communication customer satisfaction model (Bae, 2003), in order to empirically test consumption of MP3P and its satisfaction. The proposed model tested four constructs, company's image, product price, product design and product function, influencing customer satisfaction, which leads to affect customer loyalty. 267 survey responses were analyzed by using structural equation modeling (SEM). The results show that all constructs had significant impact. This study suggests a good understanding of consumer satisfaction and loyalty of MP3P and the future direction of MP3P research regarding to consumer satisfaction.

In the future, smartphone convergences are not only based on the on/offline integration, but also with the integration between mobile communications and broadcasts. Therefore, there is a need to search for new direction of mobile device that enables variety user applications that are different from the existing size and application issue. The aim of this research is to improve user interface of smartphone's functional attribute. We study on the analysis of smartphone's functional attribute by AHP. The survey results in this paper showed that the most preferable attribute of smartphone among the 8 was the wireless internet 25.3%, followed by messaging 20% and application 19.8%, which totaled to 62.5%. But the samples used were mostly limited to those aged 20 through 30. So the results are not considered as a representative preference of all smartphone users, and should be considered otherwise before materializing them to a product. Therefore, for the more liable results the further research should be conducted to gather data from a variety of users of all ages, and the functional attribute should be analysed through QFD.

21세기 산업 분야의 근간은 정보통신 산업이며 그 정보통신 기술의 두 축은 인터넷과 무선통신이다. 무선인터넷은 인터넷의 즉시성과 휴대전화와 개인정보단말기(PDA)의 이동성을 합한 개념으로 무선단말기를 통해 인터넷을 이용하거나 전자상거래를 할 수 있는 서비스이다. 무선인터넷은 사용자가 이동 중에도 무선망을 통해 인터넷에 접속, 원하는 서비스를 제공받을 수 있는 환경과 기술이라고 할 수 있다. 이처럼 무선인터넷의 핵심은 모바일 즉, 단순히 선이 없다는 의미가 아니라 이동중이라도 언제 어디서라도 인터넷에 접속이 가능하다는 것이다. 현재 국내 무선인터넷 시장은 각종 사업 제휴, 사업설명회, 세미나 등 무선인터넷과 관련해 활발히 움직이고 있고, 막대한 투자와 기술 개발 또한 지속적으로 진행되고 있다. 이처럼 이동통신사업자, 콘텐츠, 솔루션, 단말기 등의 거의 모든 사업자가 초기 시장 선점을 위한 경쟁이 치열하다. 무선인터넷은 이동통신과 인터넷 서비스의 결합으로 이동중에 무선으로 인터넷 정보를 송, 수신할 수 있는 서비스로서 이는 단순문자정보서비스(SMS)방식과 WAP 또는 ME 브라우저를 탑재한 무선인터넷 서비스 방식으로 구분할 수 있다. 무선인터넷은 차세대 이동통신(IMT-2000)과 접목되면서 기존 IT산업 자체를 전면 재편하게 될 것으로 전망되고있다. 하지만 무선인터넷 활성화를 위해서는 사업자들의 지속적인 기술 개발, 콘텐츠 개발, 요금 체계 개선 등도 중요하지만 정부의 정책적 배려와 무료에 익숙해져 있는 사용자들의 인식 변화 등 다양한 차원에서의 노력이 필요하다.

In this paper, we introduce an AES-based security chip for the embedded system of Internet of Things(IoT). We used Verilog HDL to implement the AES algorithm in FPGA. The designed AES module creates 128-bit cipher by encrypting 128-bit plain text and vice versa. RTL simulations are performed to verify the AES function and the theory is compared to the results. An FPGA emulation was also performed with 40 types of test sequences using two Altera DE0-Nano-SoC boards. To evaluate the performance of security algorithms, we compared them with AES implemented by software. The processing cycle per data unit of hardware implementation is 3.9 to 7.7 times faster than software implementation. However, there is a possibility that the processing speed grow slower due to the feature of the hardware design. This can be solved by using a pipelined scheme that divides the propagation delay time or by using an ASIC design method. In addition to the AES algorithm designed in this paper, various algorithms such as IPSec can be implemented in hardware. If hardware IP design is set in advance, future IoT applications will be able to improve security strength without time difficulties.
