이 논문에서는 현재 그 진위가 한국 고대사 연구의 초미의 관심이 되고 있는 화랑세기 등 고대사 저술의 진위를 판단하는 과학적 방법론을 제안하는 데 있다. 이런 방법론의 전통은 성서의 바울서한의 저자의 진위 논쟁, 세익스피어 작품의 진위논쟁 등 세계적 관심이 되는 것에서부터 정치적 사건 및 개인의 송사에까지 다양한 스펙트럼에서 논구될 수 있으며 이런 결과들은 현재 우리의 인문학계 특히 고대사학과 민족 정체성에 대한 거대 담론들에 대한 여러 형태의 유용한 실증적 전거를 마련해주게 될 것이다. 또한 다학문적, 학제적 연구의 새로운 모멘텀이 될 수 있을 것이다.

텍스트 특성을 인식하는 방법적 접근은 텍스트의 기본적 특성을 이용하는 것에서부터 다변량 기법까지 다양한 방법이 제안되고 이용되고 있다. 이 논문에서는 이런 여러 기법들 중 클러스터링 기법을 이용하여 텍스트의 특성을 인식하고 그 인식능력의 효과성을 확인하고자 하였다. p 개의 변수로 구성된 N 개의 개체들은 p-차원 공간에 흩어진 N 개의 점으로 생각될 수 있으며 이들이 어떤 의미의 조밀성을 가지고 cluster를 이루고 있는지에 대한 정보는 자료의 구조를 이해하는데 매우 중요한 의미를 가지게 된다. 이런 결과들은 현재 우리학계의 도작사건논쟁, 인문학계 특히 고대사학과 민족 정체성에 대한 거대 담론들에 대한 여러 형태의 유용한 실증적 전거를 마련해주게 될 것이다.

This paper try to provide basic insight of the changing functions of urban parks for the future direction of the maintenance and management of the urban parks using the results of the case study done for the city of Osaka, Japan. To accomplish this purpose this study considers the behavior characteristics of the elderly within the parks in Osaka, Japan. Based on the findings of the study authors propose the chaining meaning of urban parks in the users perspective and summarize the results of the study. Study results show high values on the environmental factors of the park, such as the fresh air and the shadow of trees and low values on noise and stairways in it. The multidimensional quantitative III classifies the purposes of the elderly using the parks into 3 types: a multi-use type, a walking type and a sightseeing type.

Desalting methods for chloride ions from the excavated iron objects were studied. These methods were compared with room temperature and heating condition of treating solution. During the Desalting treatments the $Cl^-$concentration of the solution were measured regularly and the plotted for $Cl^-$concentrations the square root of time, heating methods showed that the $Cl^-$ ions are more extracted. For the desalting treatments these plots were found to be flattening line, it was showed the changing second solution. Also, the changing solution in the room temperation detected less $Cl^-$ ions of heating treatment solution. As the examination for the relative humidity has compared for desalting objects during 8 days, it was showed a re-corroded appearance of R.H90%. As it did not detected a $Cl^-$ ions of re-corroded section, these phenomena were showed the naturally occuring corrosion of the objects in the high relative humidity.

This is the second of two part series on experimental studies of grout type transverse joints. In this paper, grout-type transverse joints between precast concrete slabs are tested to study the fatigue behavior. The tests are per-formed with loading equipment designed and constructed especially in the lab to introduce shear fatigue failures on the joints of the test specimens with repeated loads. Non-prestressed as well as prestressed specimens are selected based on static tests and these specimens are studied to identify the effect of prestress on the fatigue strength of the grout type joint. A comparison between prestressed and non-prestressed specimens indicates that longitudinal prestressing is an effective method to increase fatigue strength of the transverse joints. Based on the fatigue test, a rational estimation of the fatigue strength is proposed to aid design of the grout-type transverse joints.

This article begins by exploring recent developments in the use of the world wide webs in language testing about what a Web-based language test (WBT) is and how they are used in language testing. After a brief review of computer-based testing, WBTs are defined and categorized as low-tech or high tech. Since low-tech tests are the more feasible, they will constitute the focus of this paper. Next, item types for low-tech WBTs are described, and validation concerns that are specific to WBTs are discussed. After a brief overview of the combination of computer-adaptive and Web-based tests, the general advantages as well as design and implementation issues of WBTs are considered before examining the role that testing consequences play in deciding whether a WBT is an appropriate assessment instrument. It is argued that WBTs are most appropriate in low-stakes testing situations; but with proper supervision, they can also be used in medium-stakes situations although they are not generally recommended for high-stakes situations. Some possible ideas for future research are suggested.(169)

The porvision against earthquakes and aseismic design of nuclear power plants (NPPs) in Korea are composed of four stages: site-selection, design, construction, and operation stages, Since regulatory criteria are strictly applied in each stage, the NPPs in Korea are believed to have a sufficient safety against maximum potential earthquakes. However, it has been recognized that those regulatory criteria borrowed from U.S. should be replace by Korea-specific ones by using earthquake data obtained from earthquake observation at and around NPP sites. Also, the government made a plan after the Yongwol and th Kyongju earthquakes that the regulatory body operates an independent earthquake network in order to reinforce the earthquake preparedness of NPPs. In compliance with the government's plan, this project is aiming at deployment of an earthquake motoring network composed of four seismic stations at NPP sites to record earthquake ground motions at NPP sites, to derive attenuation formulas of various ground motions and site-specific response spectra, and to develop structural intergrity assesment program.

Topology processing is indispensable basic function as it generate a real-time BUS-BRANCH model in Energy Management Systems because most application softwares such as state estimation, power flow, etc., require BUS-BRANCH circuit data. This paper propose an expert system to generate BUS-BRANCH circuit model using Artificial Intelligence technology and it is applied to 154kV distribution substations.

For the study of the pigments on lacquer with wooden for comparing a characteristics and chemical structures have been selected samples from tombs at Tanwol-dong, Ch′ungch′ong-do, Hwang-namtaech′ong, Anapchi Lake in Kyongju-shi and Miruksa Site. Analysis showed that red pigments on the lacquer with wooden from Anapchi Lake and Tomb at Tanwol-dong was found to Cinnabar, and those sample sexcavated from Hwang-namtaech′ong have been analyzed to calcite, maghematite and kornelite. In general, red pigments have two components like cinnabar and hematite. Hematite was found that red lacquer at Hwang-namtaech′ong was to beidentified Maghematite caused by their environment air pollution. Cinnabar was handled more valuable than hematite for unchanging characteristics for their colour under same condition since old times.
