  • We proposed that is suitable network environment and wire/wireless communication network, easy of implementation, security level preservation, scalable & reconfigurable to TCP/IP protocol architecture to implement suitable smart card MS-Serpent cryptographic algorithm for smart card by hardware base chip level that software base is not implement. Implemented MT-Serpent cryptosystem have 4,032 in gate counter and 406.2Mbps@2.44MHz in throughput. Implemented MS-Serpent cryptographic algorithm strengthens security vulnerability of TCP/IP protocol to do to rescue characteristic of smart card and though several kind of services are available and keep security about many user in wire/wireless environment, there is important purpose.

  • 최근 사물인터넷 분야에서 스마트 팩토리 부분은 많은 주목을 받고 있으며 관련된 연구도 많이 진행되고 있다. 기존의 스마트 팩토리 플랫폼은 제품 생산 효율성을 높여 비용을 줄이는 것을 목표로 센서로부터의 데이터 수집과 클라우드로의 전송, 대규모 데이터 분석을 통한 의사결정 등 자동화 부분에 집중되어 있다. 본 논문에서는 웹 GUI를 활용하여 응용 개발의 편의성을 높여 개발자가 아닌 공정관리자가 직접 공정을 제어할 수 있도록 했으며 유사 환경이 구축된 다른 공장에서 기존에 만들어진 공정 프로그램을 공유하고 재수정할 수 있는 시스템을 설계하였다. 또한, 프로토타입을 구현하여 제안된 웹 GUI기반 스마트 팩토리 공정 관리 및 공유 시스템의 운용 가능성을 검증하였다.

  • The purpose of testability analysis is to estimate the difficulty of testing a stuck-at fault in logic circuits. A good testability measurement can give an early warning about the testing problem so as to provide guidance in improving the testability of a circuit. There have been researches attempting to efficiently compute the testability analysis. Conventional testability measurements, such as COP and SCOAP, can calculate the testability value of a stuck-at fault efficiently in a tree-structured circuit but may be very inaccurate for a general circuit. The inaccuracy is due to the ignorance of signal correlations for making the testability analysis linear to a circuit size. This paper proposes an efficient method for computing testability analysis, which takes into account signal correlation to obtain more accurate testability. The proposed method includes the algorithm for identifying all reconvergent fanouts in a given n circuit and the gates reachable from them, by which information related to signal correlation is gathered.

  • The purpose of the study was to show the development process of the total instructional alignment based on the 2015 revised technology home economics curriculum, and to present the detailed aspects of this task. The results of this study were as follows: First, the clarity phase of the performance established the annual evaluation plan to ensure the consistency of the achievement standard, the learning objectives and the assessment objectives through an analysis of the curriculum. Second, the development phase of the performance tasks and the grading criteria analyzed the contents area and determined the performance assessment task. The performance assessment consisted of a portfolio and project activity types, and also comprised of knowledge markets, as well as e-NIE tasks, including individual tasks and collective tasks. Third, the performance assessment and the results phase were conducted after planning the class operation according to the instructors' directions and arrangement of the schedule into block classes. Afterwards, the performance assessment tasks were revised by the teaching-learning community and class reflection on practical application. As these results demonstrate, developing performance tasks that are centered on the learner's development processes can contribute to teachers' expertise and improvement of instruction.

  • This study has been carried out to provide marketing materials concerning recognition of parents and students for operators of private cooking education institutes and useful information for the parents who are to send their children to such training institutes, by identifying the effects of the quality of educational services and educational environment of cooking education institutes on satisfaction and positive recommendation intention of trainees. Especially, educational services and educational environment of cooking education institutes that provide education to foster skilled workforce in specialized culinary area were analyzed in detail to draw effective data. Firstly, it has been studied if educational services of cooking education institutes such as educational contents, service of instructors and educational service quality had positive effects on the level of satisfaction about the institutes. Secondly, looking into effects of satisfactory environmental service of cooking education institutes, such as educational environment and quality of administration, on behavioral intention, it has been surveyed that all factors affected satisfaction of students. Thirdly, as for the effect of use intention of action of cooking education institute on positive recommendation intention of trainees, it has been shown that satisfaction with educational services and environment had an effect on positive recommendation intention as well as on intention of reregistration. Therefore, it can be suggested that marketing strategies and management strategies need to be established in a way that quality of education services and educational environment provided by cooking education institutes can render positive behavioral intention to customers of cooking education and the education market through differentiated strategy establishment.

  • 우리나라 연구소의 소규모 검색체계에서는 시소러스를 이용하지 않고 검색체계를 유지해도 별 문제가 없다는 생각을 가져온 것이 사실이다. 그러나 현실적으로는 검색효율이 극히 저조하고 잡음율이 높을 뿐만 아니라 필요한 정보의 접근이 불가능한 경우까지도 있다. 그래서 과연 현 체계대로 검색했을때 검색효율 즉 적합율과 재현율은 어느 정도 인가를 실험을 통해서 측정해 보았더니 극히 저조하다는 결론을 얻었고 그 원인을 분석해 보았다.

  • 최근 컴퓨터와 인터넷의 급속한 보급으로 인해 물리적 시공간의 한계를 뛰어 넘어 언제, 어디서나 자신에게 필요한 학습활동을 할 수 있는 기반이 조성되면서 e-러닝(e-Learning)에 대한 관심이 커지고 있다. e-러닝은 '학습 선택권의 확장'과 '학습 기회의 확대'를 통해 궁극적으로 언제(anytime), 어디서(anywhere), 누구나(anyone) 학습할 수 있는 '열린 학습'을 지향하며 기존 교육 패턴과는 전혀 다른 새로운 패러다임을 요구하고 있다[1. 즉, e-러닝의 성패는 '기존 방식과는 다른 방식으로 교육을 설계할 수 있느냐?'와 '학습자들의 학습 습관이 어느 정도 변화했느냐?'에 따라 달라진다. 또한 기업에서는 e-러닝을 조직의 비즈니스 전략과 유기적으로 연동시키는 전략이 성패의 갈림길이다 할 수 있다.
