Although the Korean government is making great effort to prevent the redundancy in IT investment and efficiently allocate the IT budget, actual achievements are quite limited because of the variety of IT resources and different architecture description among organizations and projects. Thus, a standardized description model of the system architecture is strongly needed to identify the common resources and improve the efficiency of IT investment. Therefore, in this paper, we have developed the function-network matrix model which can be used as the basic template for a standard for architecture description of e-Government systems. The function-network matrix model integrates the function tiers and the network areas into a single unified framework, which enables the functionality of each component and the flow of information clearly visible. Moreover, we described the architectures of Korean e-government’s citizen service systems using our model, resulting in clear demonstration of the similarities and differences between different systems, and easy identification of the common resources. Using the architecture description model developed in this research, the consolidation of national IT resources can be promoted, and non-expert IT users can easily recognize the architecture of their systems. In addition, more efficient and systematic IT resource management can be achieved using our model. 정보화에 대한 꾸준한 정책적 지원과 투자를 통하여 우리나라의 전자정부는 세계 6위 수준으로 평가되는 등 괄목할 성과를 이루었으나, 각 부처별로 정보시스템을 구축 운영함으로써 중복투자 및 정보자원 공동 활용 미흡 등의 문제가 발생되고 있다. 따라서 전자정부 시스템 정보자원에 대한 통합적 관리노력을 추진 중이나, 현재 시스템 아키텍처에 대한 서술 방식이 상이하여 이해관계자간의 의사소통을 저해하는 요인으로 작용하고 있다. 이에 따라 공동활용 가능한 정보자원을 명확히 식별할 수 있는 시스템 아키텍처의 표준적인 서술(standardized architecture description) 방안 수립이 절실히 요구된다. 본 연구에서는 전자정부 시스템 아키텍처의 표준적 서술 기반을 제공하는 기능-네트워크 매트릭스 모형(function-network matrix model)을 제안하였다. 기능-네트워크 매트릭스는 기능계층 구분을 열로, 네트워크 영역 구분을 행으로 나타내어, 기능계층과 네트워크 영역을 통합하여 표현할 수 있는 모형이다. 기능-네트워크 매트릭스를 활용하여 전자정부 민원행정시스템 및 행정업무시스템을 대상으로 적용한 사례를 제시하였다. 이를 통하여 서로 다른 시스템간의 아키텍처의 공통점과 차이점을 명확히 파악하고, 시스템간 정보자원의 공동활용 및 시스템 통합을 위한 정보자원 식별의 가능성을 확인하였다.

컴퓨터가 인간처럼 문제를 풀 수 있기 위해서는 불확실한 지식을 표현하고 추론(reasoning)할 수 있어야 한다. 최근 인공 지능 분야에서는 일차 논리를 확장시키는 방향으로 이에 대한 연구가 활발히 진행되고 있다. Ginsberg에 의해 제안된 MVL(Multi Valued Logic)에서는 사용자가 진리값과 논리적 연산을 지정해 줌으로써 일차 논리의 제약성을 해결하고 있다. 본 논문에서는 MVL에서의 논리 체계 환경 설정을 위하여 사용자가 양격자 구조를 그림으로 표현하고 이로부터 그에 해당하는 리스프 프로그램을 자동 생성함으로써 논리 체계 설정을 용이하게 하는 그래픽 인터페이스 시스템을 제안하였다.

We made densified wood pellet by hemp woody core as replacing wood resource. Hemp was separated into the bast fiber and the woody core by hot steaming treatment. The hemp woody core had a similar lignin content and carbohydrate composition with hardwood. Also, the hemp had a low ash content, which resulted in a low ash formation in pellet burning. Heating value of the hemp pellet had a very similar to the pellet made by hardwoods. The hemp woody core can replace hardwood for densified wood pelletmaking.

The electron beam irradiation was applied as a pretreatment of the enzymatic hydrolysis of yellow poplar with doses of 0sim450 kGy. The higher irradiation dose resulted in the more degradation of hardwood biomass not only from carbohydrates but also from lignin. This changes originated from the irradiation resulted in the better response to enzymatic hydrolysis with commercial cellulases (Celluclast 1.5L and Novozym 342). The more improvement on enzymatic hydrolysis by the irradiation was found in the xylan than in the cellulose of yellow poplar.

In second step of concentrated acid hydrolysis, part of xylose and glucuronic acid was converted to furfuraldehyde and formic acid. Formation of furfuraldehyde was come from xylose, which highly sensitive to reaction temperature. Formation of formic acid was come from both xylose and glucuronic acid, which supposed to main inhibitor in biobutanol fermentation.

The purpose of this study was to examine enhancement of English reading motivation as university students utilized self-reflective journals and web-based learning in an EFL classroom. 20 university students who took a reading course as the required course during their freshmen year participated in this study. The data were collected through the course of an academic semester. In order to gain an in-depth understanding of participants` reading motivation, the interview and self-reflective journals were analyzed by using an open-coding and content analysis. The results showed that the students increased their intrinsic motivation in reading facilitated by interest and curiosity of reading through self-reflective journals as well as web-based learning. And the students` self-reflective journals positively affected their self-directed learning which provided the students an opportunity to be student-centered and take responsibility for their own learning that enhanced students` motivation. Through writing self-reflective journals, the students became aware of their learning process, as well. Self-reflective journals enabled the students to utilize language strategies, especially a meta-cognitive strategy. Finally, the study suggested some considerations for future research on how to utilize a reflective journal effectively in order to increase students` reading motivation.
