An archives collects and manages a variety of records and archives including information reflecting the phases of the times and has a role in society as archive information center. Also, archives support that users can efficiently search and use records. Although archives has a variety of records and archives, users and non-users has low recognition on it. This study aims to find factors why people don't use archives and analyzes requirements to utilize archives activation for users and non-users. To perform the goals, questionnaires were used to collect data from 148 domestic people. Also, this study used descriptive statistics and independent t-test to analyze the collected data. With the analyzed results, this study proposed suggestions to improve user's perception and factors for activation of archives.

Green roofs are being created in various purposes to use spaces. Most of them have been built with a goal as a resting place. However, the use of the green roofs needs to be raised. Otherwise, maintenance and administration of green roofs can be loosened. In addition, budget or cost involved can be wasteful. Therefore, this study makes a proposition if the satisfaction of green roofs is higher, the use of green roofs could be increased more. We are willing to analyze how beneficial the awareness can affect for the satisfaction with regard to green roofs. The findings can be helpful to provide a foundation data for raising the use of green roofs. We believe that the awareness benefits and satisfaction could be different depending on the facility's status on green roofs. Therefore, we classified green roofs of 11 department stores, in Seoul, into four types. Among them, we paid attention to five department stores that were able to represent each type. We analyzed the awareness benefits and satisfaction depending on the type of green roofs. We analyzed casual relationships between them using Structural Equation Modeling. We expect that the landscape architecture scholars will expand research on the various determinants in using green roof. een Roof; Type of Green Roof; Benefit Awareness; Satisfaction; Structural Equation Modeling;

정부는 자전거 이용활성화에 관한 법률」을 1995년에 제정하여 지자체별 자전거이용시설의 정비계획을 수립하도록 하였지만 실제적으로 수립되고 있는 많은 정비계획들이 아직 초기단계기고, 사전에 충분한 시간을 갖고 세밀한 분석과 연구 없이 수립되다보니 상위계획과의 연계성부족과 지역적 특성에 부합되는 계획안 부족, 도로설계기술의 부족 등 많은 부분에서 문제점들이 지적되고 있다. 따라서 보다 발전한 연구내용의 계획으로 실제적으로 자전거 활성화에 기인하기 위해서 도출되는 문제점들을 진단하고 수정 분석하여 보완하는 작업이 필요하다. 본 연구에서는 1995년부터 1998년 상반기까지 내무부에서 검토된 자전거이용시설 정비계획 보고서 중 10개 도시에 대하여 각도시별 정비계획의 문제점을 현황조사부분과 분석부분 계획부분으로 분류하여 분석하고 이의 개선방향을 제시하였다.

본 고에서는 현재 서비스하려고 하는 무선데이터 통신의 방식에 대한 망 구성 및 특징들에 대해 살펴보고, 기존망을 이용한 서비스와 전용망을 이용한 서비스를 비교하였다. 또한, 전용망들(모토롤라의 DataTAC과 에릭슨의 Mobitex)을 비교하였다. 기존망을 이용한 방식과 전용망을 이용한 방식의 비교는 국내 무선데이터 통신서비스 활성화 측면, 국내 기술개발 활성화 측면, 그리고 국제 경쟁력 강화 측면에 대하여 비교하였으며, 전용망을 이용한 두가지 방식 사이의 비교는 우선 외향적인 제원, 망 신뢰성 및 확장성, 시스템 각 부분별 성능, 각 제조업체의 시스템 설치 및 지원에 관한 사항을 비교하였다.

This study deals with current use of e-books through a survey of e-book audiences and a diagnosis of the development perspective of e-book audiences. In addition, we present some effective methods to promote e-books in the future. The study shows that e-book users have increased. However, e-books are not well-known to the audience. Mainly, audiences use free web sites; consequently, the use of e-books is not well-promoted. Whether people have used e-books is statistically significant in the pattern of their use and e-book audiences prospect that the future of e-books is brighter than paper books. However, people who have used e-books prospect the brighter future for e-books than people who have never used them. Therefore, we should reconsider the accessibility to e-books, promote publicity, research the reliability of the contents, reduce the price, develop various contents, change layout for better readability, and develop the screen for the less eye fatigue to promote e-books.

The immobilization of proteins on silicon surfaces using electrochemical reaction has been studied. Chemical deposition of nitrobenzendiazonium (NiBD) cations is employed to modify silicon surfaces. Electrochemical reduction of nitro-group to primary amine-group have been conducted on the modified surfaces to activate silicon surfaces for the protein immobilization. Attachment of gold nanoparticles was used to prove the reduction. The current method was applied to selective activation of a silicon nanowire and immobilize proteins on the selected nanowire. It has been demonstrated that the use of chemical and electrochemical reaction NiBD is efficient for the selective immobilization of proteins on silicon nanowire surfaces.

In this raper, an enhanced learning method is proposed for improving the learning speed of the error back propagation learning algorithm. In order to cope with the premature saturation phenomenon at the initial learning stage, a variation scheme of active functions is introduced by using higher order functions, which does not need much increase of computation load. It naturally changes the learning rate of inter-connection weights to a large value as the derivative of sigmoid function abnormally decrease to a small value during the learning epoch. Also, we suggest the hybrid learning method incorporated the proposed method with the momentum training algorithm. Computer simulation results show that the proposed learning algorithm outperforms the conventional methods such as momentum and delta-bar-delta algorithms.

The purpose of this study is to suggest a model for increasing international use of Korean scholarly journals. Recently DOI and open access are remarkable from the standpoint of increasing the opportunity of global exposition and citation of domestic scholarly journal papers. The data used in investigation and analysis were from KAMJE, KISTI, DOAJ and SCIMAGO. The model comprising DOI service and open access is obtained through analyzing DOI and open access utilization models and investigation on both.

Purpose : To compare fMRIs of visual and auditory word generation tasks, and to evaluate the difference of its activated areas and lateralization according to the mode of stimuli. Materials and Methods : Eight male normal volunteers were included and all were right handed. Functional maps were obtained during auditory and visual word generation tasks in all. Normalized group analysis were performed in each task and the threshold for significance was set at p<0.05. Activated areas in each task were compared visually and statistically. Results : In both tasks, left dominant activations were demonstrated and were more lateralized in visual task. Both frontal lobes (Broca's area, premotor area, and SMA) and left posterior middle temporal gyrus were activated in both tasks. Extensive bilateral temporal activations were noted in auditory task. Both occipital and parietal activations were demonstrated in visual task. Conclusion : Modality independent areas could be interpreted as a core area of language function. Modality specific areas may be associated with processing of stimuli. Visual task induced more lateralized activation and could be a more useful in language study than auditory task.

Activated carbons were prepared from pine bark by steam activation, and pore structures and specific surface areas were then investigated. Three different types of kilns were used for the activation. When the stationary-vertical-or stationary-horizontal-type kiln was used for the steam activation to prepare an activated carbon from the bark, it was not possible to produce activated carbon having high specific surface areas exceeding 1,000 $m^2／g$. Using bark powder improved the specific surface area, but it was still not high enough. When the rotary-horizontal-type kiln was used for the activation, the activated carbons prepared had high specific surface areas of more than 1,000$m^2／g$, which was similar to a commercial first-grade activated carbon. The activated carbon prepared by the rotary kiln had a wide distribution of pore size ranging from microporous to mesoporous.
