In this paper, we design an 8-bit eSuse OTP (one-time programmable) memory in consideration of EM (electro-migration) and eFuse resistance variation based on a $0.18{\mu}m$ generic process, which is used for an analog trimming application. First, we use an external program voltage to increase the program power applied an eFuse. Secondly, we apply a scheme of precharging BL to VSS prior to RWL (read word line) activation and optimize read NMOS transistors to reduce the read current flowing through a non-programmed cell. Thirdly, we design a sensing margin test circuit with a variable pull-up load out of consideration for the eFuse resistance variation of a programmed eFuse. Finally, we increase program yield of eFuse OTP memory by splitting the length of an eFuse link.

The evolution of transaction-based business model is upon us. The business models of many e-Marketplace in their early stages have typically been based on transaction fees. Many e-Marketplaces have even called out transaction revenues as a core element of their business plans. The transaction business represents the most simple of business models, but it does not provide a long-term sustain able advantage. For buyer's convenience, wide selection and test price hold appeal. For suppliers, the extended global market reach and direct access to customers and consortiums of customers is powerful. To maxmize leverage of these new e-marketplace, you must from both a buyer perspective as well as a supplier perspective. Also required is a strategy that takes in account all of the various e-Marketplace transaction standards and one that allows the easy accomodation to new e-marketplace as the market change. These new e-marketplace will need to be factored into the sales channel strategies. To be successful, integration with these e-marketplaces should occur at a complete business process level. This study explored independent and industry-backed current and future business models that are emerging in the B2B electronic market industry, as well as value -added service models for the Net market maker industry. E-Marketplaces will evolve into digital work environments in which real industry collaboration can occur.

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.

Environmental DNA (eDNA) is a genetic material derived from organisms in various environments (water, soil, and air). eDNA has many advantages, such as high sensitivity, short investigation time, investigation safety, and accurate species identification. For this reason, it is used in various fields, such as biological monitoring and searching for harmful and endangered organisms. To collect eDNA from a freshwater ecosystem, it is necessary to consider the target organism and gene and a wide variety of items, such as on-site filtration and eDNA preservation methods. In particular, the method of collecting eDNA from the environment is directly related to the eDNA concentration, and when collecting eDNA using an appropriate collection method, accurate (good quality) analysis results can be obtained. In addition, in preserving and extracting eDNA collected from the freshwater ecosystem, when an accurate method is used, the concentration of eDNA distributed in the field can be accurately analyzed. Therefore, for researchers at the initial stage of eDNA research, the eDNA technology poses a difficult barrier to overcome. Thus, basic knowledge of eDNA surveys is necessary. In this study, we introduced sampling of eDNA and transport of sampled eDNA in aquatic ecosystems and extraction methods for eDNA in the laboratory. In addition, we introduced simpler and more efficient eDNA collection tools. On this basis, we hope that the eDNA technique could be more widely used to study aquatic ecosystems and help researchers who are starting to use the eDNA technique.

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.

In this paper, a 5V small-area NMOS-diode eFuse OTP memory cell is proposed. This cell which is used in PMICs consists of a 5V NMOS transistor and an eFuse link as a memory part, based on a BCD process. Also, a regulated voltage of V2V ($=2.0V{\pm}10%$) instead of the conventional VDD is used to the pull-up loads of a VREF circuit and a BL S/A circuit to obtain a wider operational voltage range of the eFuse memory cell. When this proposed cells are used in the simulation, their sensing resistances are found to be $15.9k{\Omega}$ and $32.9k{\Omega}$, in the normal read mode and in the program-verify-read mode, respectively. Furthermore, the read current flowing through a non-blown eFuse is restricted to $97.7{\mu}A$. Thus, the eFuse link of a non-blown eFuse OTP memory cell is kept non-blown. The layout area of the designed 1kb eFuse OTP memory IP based on Dongbu HiTek's BCD process is $168.39{\mu}m{\times}479.45{\mu}m(=0.08mm^2)$.

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.

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.
