본 논문에서는 아날로그 트리밍용으로 사용되는 $0.18{\mu}m$ generic 공정 기반의 EM(Electro-Migration)과 eFuse의 저항 변동을 고려한 8bit eFuse OTP (One-Time Programmable) 메모리를 설계하였다. eFuse OTP 메모리는 eFuse에 인가되는 program power를 증가시키기 위해 external program voltage를 사용하였으며, 프로그램되지 않은 cell에 흐르는 read current를 낮추기 위해 RWL (Read Word-Line) activation 이전에 BL을 VSS로 precharging하는 방식과 read NMOS transistor를 최적화 설계하였다. 그리고 프로그램된 eFuse 저항의 변동을 고려한 variable pull-up load를 갖는 sensing margin test 회로를 설계하였다. 한편 eFuse link의 length를 split하여 eFuse OTP의 프로그램 수율 (program yield)을 높였다.

e-Marketplace는 B2B 거래의 한 종류로서 인터넷상에서 불특정 다수의 공급자와 수요자(N:N)간 비즈니스 거래를 유발시켜 주는 가상의 시장인데 전세계적으로 특정 산업에 한정된 수직적인 e-Marketplace와 특정 산업과 관계없는 수평적인 e-Marketplace형태로 발전되고 있다. e-marketplace는 구매자와 판매자에게 제공하는 이점들 때문에 놀라운 속도로 증가하고 있다. 구매자입장에 e-marketplace는 새로운 공급업체를 물색하는 과정에서 들어가는 구매비용을 낮출 수 있다. 공급업체의 경우 e-Marketplace는 판매비용을 낮추고 새로운 고객에게 물품을 납품할 수 있는 기회를 제공한다. 이에 e-marketplace 기업들도 분명한 비즈니스모델로서 경쟁력 있는 업체만이 생존할 것이다. 이러한 생존에서 살아남기 위해서는 치열한 경쟁을 이겨내야 한다. 이에 대한 구매자와 판매자의 역할이 무엇인지를 살펴 보는 것이 본 연구의 목적이다.

환경유전자(eDNA)는 다양한 환경(수중, 토양, 대기)에 존재하는 생물체로부터 유래된 유전물질을 의미한다. eDNA는 높은 민감도, 짧은 조사시간 등 많은 장점들이 존재하며 이로 인해 생물 모니터링 및 유해생물과 멸종위기 생물을 탐색하는 분야에 다양하게 활용되고 있다. 이러한 eDNA를 채집하기 위해서는 대상생물 및 대상유전자뿐만 아니라 현장 여과방법 및 eDNA 보존방법과 같이 매우 다양한 항목들을 고려해야 한다. 특히 환경에서 eDNA를 채집하는 방법은 eDNA 농도와 직결되는 항목으로서 적절한 채집방법을 사용하여 eDNA를 채집할 때 정확한 분석결과를 얻을 수 있다. 또한 현장에서 채집한 eDNA를 보존하고 추출하는 과정에서도 정확한 방법을 사용하였을 때 현장에 분포하는 eDNA의 농도를 정확하게 파악할 수 있다. 특히 eDNA 연구를 시작하는 연구자들에게 eDNA 분야는 초기 진입 장벽이 매우 높은 기술로서 이를 위한 기초 자료가 매우 절실하다. 본 연구에서는 본 연구는 eDNA가 수생태계를 연구하기 위한 도구로서 보다 널리 이용되며, eDNA를 이용하기 시작하는 연구자들에게 도움을 주고자 수생태계에서 eDNA를 채집하고 및 운반하는 방법과 실험실에서 eDNA를 추출하는 방법을 소개하고, 보다 간편하고 효율적인 eDNA 채집 도구와 방법을 제시하였다.

The purpose of this study was 1) to understand the job transfer in education & training(E&T) programs & organizational situational characteristics, and 2) to analyze the effects of the E&T programs & organizational situational characteristic groups on each of the levels of job transfer. There is intimate relationship between E&T programs characteristics & organizational situational characteristics and job transfer, so we can't think of them separately. With this point of view the most frequently discussed problem is how to apply the theory in actual job, but in reality it's true that the improvement of job transfer can't reach the expectations of the E&T programs. In literature view study, the concepts of job transfer in E&T, the general theory on E&T, and the actual condition and points at issue of the existing E&T practices in the medium and small-sized hospitals were defined. As the results from empirical analysis, we could find followings: First, in evaluation of the job transfer, demographic characteristics (seniority, occupational category, position) variables have a significant different. Second, in degree of the job transfer, E&T programs characteristics(contents of E&T, design of E&T, conditions of E&T, teaching ability of lecturer, methods of E&T) variables have a different influence upon each of the evaluation levels of E&T. Third, support of CEO variables have a different influence on the job transfer according to contents, design, conditions of the E&T programs. Fourth, support of co-works variables have a different influence on the job transfer according to design, conditions, method of the E&T programs. Fifty, support of organizational atmosphere variables have a different influence on the job transfer according to contents, design, conditions of the E&T programs.

This study identified the effectiveness of e-learning by comparing learning outcome in conventional face-to-face lecture with the selected e-learning methods. Two e-learning contents (animation based and video based) were developed based on the rapid prototyping model and loaded onto the learning management system (LMS), which is http://www.enaged.co.kr. Fifty-four Korean agricultural high school students were randomly assigned into three groups (face-to-face lecture, animation based e-learning, and video based e-learning group). The students of the e-learning group logged on the LMS in school computer lab and completed each e-learning. All students were required to take a pretest and posttest before and after learning under the direction of the subject teacher. A one-way analysis of covariance was administered to verify whether there was any difference between face-to-face lecture and e-learning in terms of students' learning outcomes after controlling the covariate variable, pretest score. According to the results, no differences between animation based and video based e-learning as well as between face-to-face learning and e-learning were identified. Findings suggest that the use of well designed e-learning could be worthy even in agricultural education, which stresses hands-on experience and lab activities if e-learning was used appropriately in combination with conventional learning. Further research is also suggested, focusing on a preference of e-learning content type and its relationship with learning outcome.

본 논문에서는 PMIC 칩에 사용되는 BCD 공정기반에서 5V NMOS 트랜지스터와 기억소자인 eFuse 링크로 구성된 저면적의 5V NMOS-Diode eFuse OTP 셀을 제안하였다. 그리고 eFuse OTP 메모리 IP가 넓은 동작전압 영역을 갖도록 하기 위해서 VREF 회로와 BL S/A 회로의 풀-업 부하 회로에 기존의 VDD 파워 대신 voltage regulation된 V2V ($=2.0V{\pm}10%$)의 전압을 사용하였다. 제안된 VREF 회로와 BL S/A회로를 사용하므로 eFuse OTP IP의 normal read 모드와 program-verify-read 모드에서 프로그램 된 eFuse 센싱 저항은 각각 $15.9k{\Omega}$, $32.9k{\Omega}$으로 모의실험 되었다. 그리고 eFuse OTP 셀에서 blowing되지 않은 eFuse를 통해 흐르는 읽기 전류를 $97.7{\mu}A$로 억제하였다. 그래서 eFuse OTP 셀의 unblown된 eFuse 링크가 unblown 상태를 그대로 유지되도록 하였다. 동부하이텍 130nm BCD 공정을 이용하여 설계된 1kb eFuse OTP 메모리 IP의 레이아웃 면적은 $168.39{\mu}m{\times}479.45{\mu}m(=0.08mm^2)$이다.

The construction of the students knowledge in e-Learning systems, namely the student modeling, is a core component used to develop e-Learning systems. However, existing e-Learning systems have many problems to share the knowledge in a heterogeneous student model and a distributed knowledge base. Because the methods of the knowledge representation are different in each e-Learning systems, the accumulated knowledge cannot be used or shared without a great deal of difficulty. In order to share this knowledge, existing systems must reconstruct the knowledge bases. Consequently, we propose a new a Case Markup Language based on XML in order to overcome these problems. A distributed e-Learning systems fan have the advantage of easily sharing and managing the heterogeneous knowledge base proposed by CaseML. Moreover students can generate and share a case knowledge to use the communication protocol of agents. In this paper, we have designed and developed a CaseML by using a knowledge markup language. Furthermore, in order to construct an intelligent e-Learning systems, we have done our research based on the design and development of the intelligent agent system by using CaseML.

To date most of the research concerning e-service quality in the context of online apparel settings has had a female or a generalized for gender and age focus. To expand the scope of understanding of online consumers, this study focuses on the key dimensions of e-service quality which affect male Generation Y consumers' e-satisfaction which in turn may affect their e-loyalty. A convenience sample of male college students was recruited from a Korean university. The findings of this study showed that privacy, personalization, efficiency, and website design were the key dimensions that have significant positive relationships with e-satisfaction. The positive relationship between e-satisfaction and e-loyalty was also confirmed. Managerial implications and suggestions for further research are further discussed.

The purpose of this research is to investigate the current state of e-commerce for corporations in the steel industry and to analyze the factors that led failure in active use of e-commerce. Data from 51 companies are col looted. Factors that affect the e-commerce adoption and use of were analyzed. The influence of e-commerce utilization on corporate performance was also examined. It was found that several factors known to influence e-commerce use in the steel industry such as transact ion methods, preferences, and the level of information-orientation, did not actually have a significant impact. Rather items such as the maturity of e-commerce experience and perceptual compatibility between product characteristics and e-commerce turned out to have a significant influence on the utilization levels of e-commerce. The level of e-commerce utilization in system had a significant impact on each of the three performance dimensions : internal performance, external performance and financial performance.
