This study intends to make a comprehensive inquiry about the intellectual foundation of cataloging research in Korea. Emphasis was on analyzing how both Pertinent and indigenous the Korean cataloging theory and practice have been developed to the Korean bibliographic environments. To the end, this study collected and examined exhaustively the research articles produced from the early 1950's to the Present In Korea. These articles are divided and reviewed into four periods: the period of (1) beginning research activities, (2) compiling the Korean cataloging tools, (3) applying cataloging automation, (4) introducing metadata. The focus was on investigating their intrinsic values and philosophies about information organization.

현재의 지식 사회에 대응하기 위하여 교육인적자원부, 시 도 교육청 각종 교육관련 기관은 다량의 교육용 콘텐츠를 개발하고 보급하였다. 그러나 교육용 콘텐츠에 대한 질 관리에 대해서는 개념도 불명확하고 법이나 규정도 미비하여 국가수준의 질 관리방법이나 절차도 체계성을 가지지 못하고 있어 양질의 자료 선별과 품질이 관리된 특화된 정보를 사용자에게 제공하는 기회가 부족하였다. 본 연구는 양질의 콘텐츠를 선별 탑재하기위해 기존의 정량적 평가 방법에 정성적 평가 방법을 보완하여 콘텐츠 특성에 맞는 평가를 할 수 있는 지침을 마련하였다.

This study develops composite indicators that is capable of estimating QOS (Quality of Service) of pedestrians by enhancing estimation for Level of Service in present transporting spaces for pedestrians that merely concerns quantitative indicators such as pedestrian flow rate, pedestrian stoppage. This paper conducts survey questionnaire to collect data. It utilizes AHP(Analytic Hierarchy Process) and ANP(Analytic Network Process). The main results show that: first, ANP is better analytic methods than AHP due to the fact that pedestrians feel repetition when they judge level of service. Second, qualitative factors such as pedestrian behaviors, maintenance, scenary for pedestrians and environments should be considered. Importance of qualitative factors is higher in residential area than other areas. I expect that using qualitative indicators and quantitative indicators is appropriate in order to estimate pedestrians' QOS.

The purpose of the current study was to research scientific basis and necessity of supplementary materials for field lesson out of golf swing teaching methods. As the subject of study, skillful tour pro golfers were chosen to reinterpret field lesson results for driver swing from the viewpoint of kinematics. In addition, through precise analysis, this study developed a case to verify the validity and error of field lesson. As a result, field lesson showed a slight difference among qualitative evaluation of kinematical analysis of techniques, subjects of study, and items. Accordingly, there was a little difference between two methods in view of evaluation of errors that 5 subjects of the study have shown. However, there was a significant difference in compensation to prevent causes of error and errors. Based on instructor's experience most errors could be evaluated. Therefore, feedback for error correction based on instructor's experience showed a significant difference from qualitative evaluation of kinematical analysis of techniques. In conclusion, the following are required for correct golf swing lesson; instant feedback through field lesson and qualitative evaluation of kinematical analysis of techniques to determine fundamental causes correctly.

본 연구의 목적은 토지자원의 유효한 개발과 관리를 위해 원격탐사 자료 및 지상자료를 이용하여 토지 이용의 예측 모형을 정립하고 실제로 제주도 지역에 적용하여 그 실증을 거치는 것이었다. 본 토형은 계절분석(multi-date processing) 및 다중분석 (multi-file processing)기법을 채택하고 Markov의 확률 이전 계산법 및 판별 함수 (discriminant function) 계산법으로부터 합성 출현된 공간적/시간적 토지이용 투영방법을 채택하였다. 판별 함수 계산법은 토지이용 변화상의 최다 경향치를 산출하기 위해 제주도 경관 평면(landscape plane) 전지역의 각 화소(pixel)에 적용되고, 확률 이전 계산법은 특정 미래 시간 간극상에서 상이한 토지이용으로 변화하는 이들 화소의 수량을 결정한다. 본 합성 모형은 이렇게 토지이용 변화성(정성적)과 그 화소의 수량(정량적)을 결합하여 경관 평면상에서 미래의 토지이용 예측을 가능케하는 것이다.

본 연구에서는 한강 상류의 소양댐 유역을 대상으로 SWAT-K 모형을 적용하여, 토지이용별, 하도구간별, 월별 및 연별 유사 발생을 비교 검토하였다. 모형 보정과 검증을 거쳐 대상유역에 대해 유출과 유사 모의의 정성적, 정량적 적용성을 검토하였으며, 이로부터 대상유역에서의 시공간적인 유사량 자료를 확보하였다. 확보된 유사량 자료를 이용하여 토지이용별 토양 유실량을 산정하고 기존 다른 연구자들의 결과와 비교함으로써 침식 영향을 판단할 수 있는 개략적인 평가를 하였다. 댐 상류로부터의 유입 유사량의 발생 원인 지역을 파악하기 위하여 모형으로부터 추정된 각 하도구간별 유사량을 오염원에 따라 점원, 비점원으로 구분하여 비교해 본 결과 비점원에 의한 영향이 99% 이상으로 나타났으며, 고랭지밭이 많이 분포한 자운천 상류유역을 제외하고는 대부분의 상류 소유역에서의 유사량이 작게 나타났다. 월별 유사량 분석 결과, 소양댐으로 유입되는 총 유사량의 88%가 여름철인 $7{\sim}9$월에 집중적으로 발생하는 것으로 나타났으며, 연도별 분석에서는 소양호의 고탁도가 문제가 되었던 2006년의 유사 발생이 다른 해에 비해 상대적으로 높은 것으로 나타났다.

In site investigation for tunnel designs, nowadays, geophysical exploration such as seismic exploration and electric resistivity exploration as well as drilling logging is frequently carried out. A method which can systematically make the utmost use of all available data obtained from investigation, therefore, is strongly required for the optimal evaluation of ground conditions in terms of rock mass class, etc. Many researchers have proposed using qualitative data to cope with the lack of quantitative data. In this study, an evaluation technique of rock mass classes in undrilled region was proposed based upon multiple indicator kriging method which is a geostatistical technique. It was shown that two types of data with different degree of uncertainty, for example, drilling logging data and geophysical exploration data, could be simultaneously utilized in evaluating rock mass classes for a real tunnel design.

This paper presents a method to enhance the performance of supervised classification by separating the spectral signature of the training data sets for each class. Using clustering technique, a training data set is divided into several subsets which show a pattern of the normal distribution with small value of spectral variances. Then a supervised classification is applied with the divided training data set as training data for the temporary subclasses of the original class. The proposed method is applied to a Landsat TM image of Busan area for the applicability test. The result shows that the proposed method produces better classified results than the conventional statistical classification methods. It is expected that the proposed method will reduce the effort and expense for selecting the training data set for each class in an area which has spectrally homogeneous signature.

Implementation of semi-public management system of intra-city bus achieve excellent results but there are some side effects like increase of the fatal traffic accidents. This study tries to develop decision making model of measures of reducing traffic accidents following implementation of semi-public management system of intra-city bus. And survey with traffic experts and analytic hierarchy process are used for data survey and analysis. Quantitative measures and qualitative measures are suggested as high assessment items of AHP. Quantitative measures of low assessment items composed of a raise in the number of bus and safety device installation, facility supplement of bus stop, supplement of pedestrian protection facility, traffic safety assessment and supplement. Qualitative measures composed of system organization, redesign bus route, reinforcement of education, campaign and enforcement. The results of this study are as follows. First, the result turns out more weights are calculated on quantitative measures than on qualitative measures. Second, It is turned out in order of facility supplement of bus stop and traffic safety assessment and supplement as the quantitative measures. Third, as qualitative measures, system organization and redesign bus route are in the order. The results of this study are considered to be a basic data which can be referred if measures on the decrease of traffic accident are established and implemented in other cities and provinces.

According to the survey data during the Japanese Occupation Period, the length of South Korea's coastline is about 11,542km, including the coastlines of mainland and islands. To accurately revise/renew this coastline data through site survey, it will cost great money and time. Also, various development projects such as reclamation works on public waters, constructions of ports/harbors, etc. This paper used aerial photographs, satellite image data and GPS survey data with certain intervals to monitor the change in coastal areas of Songieong, Haeundae, Kwanganri, Songdo and Dadaepo. The local area subjected for this research was limited to areas near Busan. The specific contents of this research include. Launching qualitative/time series analyses on the change of coastal areas using aerial photographs, satellite image data and RTK-GPS surveys.
