  • The purpose of this study is to propose a strategy to educate the core contents of various major fields in practical and convergent ways in universities in order to prepare for the 4th industrial revolution era. First, convergence field is established in the university curriculum in addition to the existing major and the liberal arts field. Second, convergence courses are created in connection with job ability, which are major curriculum but only for students in other departments. Third, convergence courses are organized in the form of module curriculum, which is a small-sized and independent curriculum consisting of 4 courses. D University, one of the local private universities in Korea, has provided such convergence module education since 2016, and satisfactory results have been obtained in the course enrollment rate and the course evaluation, etc. By combining these convergence modules in various ways, it is possible to easily create customized majors required and designed by local companies at low cost.

  • A Small-Sat Power System Design and Development should be depend on space environment such as solar wind with Electromagnetic field by hurdle of techniques. It is surmount solution of trend that will unitize and converge with power module in these days. The level of modularize means that applying Universal Middleware for payload power module requirements. The scope of target system is a main power provider module and operational subunit that can be implemented with the final power module distribution loads to consume for continuous process. A Universal Middleware strengthen to build power module from satellite power system should be accuracy and consuming data. A Power Service Module and dynamic system drive interactive management between power distribution and consumer module by Range Control. Consequently, suggesting evaluation, unexpecting payload system power consumer that makes fine variable resources in the development design process and efficiency.

  • In this paper, we design an intelligent agent system with the data mining module and information fusion module as the core components of the system and investigate the possibility for the medical expert system. In the data mining module, fuzzy neural network, OFUN-NET analyzes multi-view data and produces fuzzy cluster knowledge base. In the information fusion module and application module, they serve the diagnosis result with possibility degree and useful information for diagnosis, such as uncertainty decision status or detection of asymmetry. We also present the experiment results on the BI-RADS-based feature data set selected form DDSM benchmark database. They show higher classification accuracy than conventional methods and the feasibility of the system as a computer aided diagnosis system.

  • The purpose of this study was to evaluate the effects of an ESP module program which combines Keller's ARCS model for the $1^{st}$ grade nursing students. Students' learning motivation and academic achievement were compared between an intervention group and a control group and their perception and subjective effects on the module program were identified. Quantitative data showed that the overall level of learning motivation in the intervention group was significantly higher than that in the control group (t=2.391, p=.019). No significant difference was found on the level of academic achievement between two groups (t=0.116, p=.098). Contents analysis on the qualitative data showed that ESP module program was interesting, effective, helpful for understanding clinical settings, and giving confidence and satisfaction. According to the result, it is assumed that the ESP module program which combines ARCS model can be effective in motivating the $1^{st}$ grade nursing students to learn nursing contents and English.

  • This paper analyzes vulnerability of each service protocol used in ICT convergence industry, smart factory, smart grid, smart home, smart traffic, smart health care, and suggests technologies that can overcome security vulnerabilities. In addition, we design a service-oriented protocol security framework that allows us to quickly and easily develop security functions in an open environment by defining a security element common to protocols and designing a security module for each protocol layer including the corresponding elements. Service protocol independent security module and specialized security module, it will be possible to develop flexible and fast security system in ICT convergence industry where various protocols are used. The overall security level of the ICT service network can be improved by installing the necessary security modules in the operating system, and the productivity can be improved in the industrial security field by reusing each security module.

  • The purpose of this research is to develope and implement a convergent educational contents based on theoretical background of integrated education using agent based modeling in the ubiquitous learning environment. The structure of this contents consists of three modules that were designed by trans-disciplinary concept and situated learning theory. These three modules are: convergent problem presenting module, resource of knowledge module and learning of agent based modeling and IT tools module. After the satisfaction survey of the implemented content, out of 5 total value, the average value was 3.86 for effectiveness, 4.13 for convenience and 3.86 for design. The result of the survey shows that the users are generally satisfied. By using this u-learning contents, learners can experience and learn how to solve the convergent problem by utilizing IT tools without any limitation of device, time and space. At the same time, the proposal of structural design of contents can be a good guideline to the researchers to develop the convergent educational contents in the future.

  • 본 논문에서는 Ambipolar 실리콘 나노와이어 FET (SiNW FET)의 빛을 통한 모듈래이션을 분석하였다. Ambipolar SiNW FET를 얻기 위해서는 나노와이어가 저농도로 도핑된 실리콘이어야 한다. 실리콘의 비등방성 습식식각 이후, 산화 공정을 통한 나노와이어 제작을 통해 보론의 확산을 통해 저농도로 도핑된 실리콘 나노와이어를 제작하였다. 빛이 조사될 시에 생기는 Ambipolar SiNW FET의 모듈래이션 특성에 관해 분석하고 간단한 응용 실험을 통하여 검증하였다. 응용 실험 결과 pH 센싱의 감도는 빛을 10000 lux 조사할 경우 8.84 배 증가하였다.

  • 본 논문에서는 블루투스 장비 간 암호화를 위해 사용되는 암호화 모듈의 설계 및 구현에 관한 내용을 다룬다. 암호화 모듈은 기저 대역내에 암호화 키 생성 모듈과 암호화 엔진 모듈로 구성된다. 암호화 키 생성 모듈은 Cylink사에서 제안한 공개 도메인인 SAFER+(Secure And Fast Encryption Routine) 알고리즘을 사용하여 128bit 키를 생성한다. 그 구성은 키 치환을 위한 치환 함수(key-controlled substitution)와 선형 변환을 위한 PHT(Pseudo-Hadamard Transform)와 Armenian Shuffle 변환기로 구성된다. 암호화 엔진 모듈은 전송 패킷내의 페이로드 데이터와 생성된 사이퍼 키 스트림 데이터와 XOR연산을 통하려 암호화를 행하며 그 구성은 LFSR (Linear Feedback Shift Register)와 합 결합기로 구성된다. 이 중 암호화 키 생성 모듈은 LM(Link Manager)의 PDU(Protocol Data Unit) 패킷을 통해 상호 정보가 교환되므로 암호화키를 생성하는데 있어 시간적 제약이 덜 하다. 따라서 본 논문에서는 변형된 SAFER+ 알고리즘 구현하는데 있어 치환 함수의 덧셈과 XOR, 로그, 지수연산을 바이트 단위의 순차 계산을 수행함으로써 소요되는 하드웨어 용량을 줄이도록 설계하였다. 본 논문에서 제시한 모듈은 블루투스 표준안 버전 1.1에 근거하여 구현하였으며 시뮬레이션 및 테스트는 Xilinx FPGA를 이용하여 검증하였다.

  • This paper presents a fusion approach to sentiment detection that combines multiple sources of evidence to retrieve blogs that contain opinions on a specific topic. Our approach to finding opinionated blogs on topic consists of first applying traditional information retrieval methods to retrieve blogs on a given topic and then boosting the ranks of opinionated blogs based on the opinion scores computed by multiple sentiment detection methods. Our sentiment detection strategy, whose central idea is to rely on a variety of complementary evidences rather than trying to optimize the utilization of a single source of evidence, includes High Frequency module, which identifies opinions based on the frequency of opinion terms (i.e., terms that occur frequently in opinionated documents), Low Frequency module, which makes use of uncommon/rare terms (e.g., "sooo good") that express strong sentiments, IU Module, which leverages n-grams with IU (I and you) anchor terms (e.g., I believe, You will love), Wilson's lexicon module, which uses a collection-independent opinion lexicon constructed from Wilson's subjectivity terms, and Opinion Acronym module, which utilizes a small set of opinion acronyms (e.g., imho). The results of our study show that combining multiple sources of opinion evidence is an effective method for improving opinion detection performance.
