Texture electron diffraction pattern을 이용한 결정구조 해석 이론은 러시아어로 씌여졌거나, 영문판 저서의 일부에 간단히 소개 되어있어 이해에 어려움이 있다. 이들의 이론은 벡터의 이론과 관련된 여러 관계식을 이용해서 설명될 수 있으며, 이로서 몇 개의 식에 포함된 오류를 수정하였다.

이 논문에서는 초등학교 4학년 수학과 교육과정에서 제시하는 '무늬 만들기'의 교수학적 변환과 각색의 실제를 비판적으로 검토한다. 무늬 만들기에서의 그 무늬는 일반적으로 벽지무늬가 아니다 그것을 만드는 방식도 벽지무늬를 만드는 방식과 같지 않다. 벽지무늬 만들기가 아니라는 점에서 보면, 새로운 무늬 만들기의 맥락은 '투명 스티커 붙이기'라고 할 수 있다. 이 논문에서는 이 특정을 전제로 해서 단위조각의 모양, 새로운 무늬 만들기의 방법, 단위조각 이어 붙이기의 규칙에 관해 비판적으로 논의하고 있다 단위조각의 모양은 실질적으로 정사각형이 아니면 안된다. 주어진 단위조각을 사용하여 새로운 무늬를 만들 때, 만드는 방식의 규칙성만 제시할 수 있으면 실제로는 어떤 규칙이라도 무방하다. 주어진 단위조각으로 만드는 새로운 무늬와 벽지무늬 사이의 관계는 분명하지 않지만, 그 둘이 서로 무관하다고 보기 어렵다는 점에서, 무늬 만들기가 '잘못된 초등화(Freudenthal, 1973)'의 한 모습일 수도 있다.

This study analyzed the relationships among the components of home management system. Through this it make to explain relationship between values and planning exactly and partially to test empirically system model to home management 650 housewives were adapted as data. Cluster analysis \chi$2 and ANOVA were used as statistical analysis. The resultes are summarized as follows 1) Goal-centered planning level was higher than that of resource-centered By 2 plannings subjects were classified into 4 planning styles : active morphogenic resource-reorganized demand-reorganized passive morphostatic style. 2) A difference between terminal value patterns and planning styles was no significant but a difference between instrumental value patterns and planning styles was significant. Family life satisfaction showed significant differences by not value patterns but planning styles. Because of high family life satisfaction as output of management active morphogenic style was successful. For succ ssful planning, it was suggested that homemarkers should possess values related broadminded loving and forgiving.

This study aims to evaluate and identify the patterns of the technological competitiveness of the Korean industry. Such statistics as R&D expenditure and R&D manpower as input indexes, US patent registrations and export sales as output indexse were used. It was turned out that such industrial types as specialized-suppliers industries, scale-intensive industries and science-intensive industries showed relatively strong technical competitiveness. However, resource-intensive industries and labor-intensive industries which had maintained a competitive advantage in the 1970s and the 1980s appeared to be gradually losing their technological competitiveness. These results are by and large in accordance with the trends of export performance. This study conducted the canonical discriminant analysis in order to test the correctness of the patterns displayed in the technological competitiveness of the Korean industry. The result of the analysis showed that the five patterns of technical strength of the Korean industries are significantly independent each other for four respective variables which are used to distinguish industries. This implies that the ex ante industrial classification into five types was correct in terms of the ex post statistics, and that the patterns of technological competitiveness discovered in this study are also statistically correct.

The Intrsuion Detecion Systems(IDS) are required the accuracy, the adaptability, and the expansion in the information society to be changed quickly. Also, it is required the more structured, and intelligent IDS to protect the resource which is important and maintains a secret in the complicated network environment. The research has the purpose to build the model for the intelligent IDS, which creates the intrusion patterns. The intrusion pattern has extracted from the vast amount of data. To manage the large size of data accurately and efficiently, the link analysis and sequence analysis among the data mining techniqes are used to build the model creating the intrusion patterns. The model is consist of "Time based Traffic Model", "Host based Traffic Model", and "Content Model", which is produced the different intrusion patterns with each model. The model can be created the stable patterns efficiently. That is, we can build the intrusion detection model based on the intelligent systems. The rules prodeuced by the model become the rule to be represented the intrusion data, and classify the normal and abnormal users. The data to be used are KDD audit data.

The purpose of this study is to analyze Phenomenon of the residential movement and important factors in the city of Seoul. First, The patterns of residential location during 1975-1994 in terms of macro aspects are to be investigated. Second, Residential patterns among households based on the literature survey data in terms of micro aspects are to be indentified. Methodology applied to the study is regression analysis using 1975-1994statistical data and content analysis based on the literature survey. The results of this study are as follows : 1) The factors of residential movement in the city of Seoul are explained by the changes of the economic structure, residential environment, individual characteristics, and housing policy. That is. the development of transportation systems, the number of homeownership scheme holders, crime rates, increase of residential areas effect on the decrease of the population in the city center of Seoul 2) According to the income groups and resident characteristics, Residential location patterns are different in residential location choice and the scope of spatial migration.

In this paper, the radiation pattern of the monopole antenna mounted on the portable phone is analyzed. The analyzed model consists of a rectangular conductor box and a monopole antenna. Even though the radiation pattern of the monopole has been well known, the monopole antenna mounted on the portable phone has not been fully studied. Because of the conductor box, portable phone acts as an unbalanced dipole antenna whoe radiation patterns deviate fro those of th econventional isolated monopole antenna. Therefore, the analysis of the radiation patterns of unbalanced dopole antenna is necessary. Using the moment method, its radiation patterns are analyzed and the numerical results are verified through the measurements. In addition, the radiation patterns depending on various length of the conductor box and the monopole antenna are also presented and the dimension of the portable phone which gives excellent radiation characteristics are derived from the analyzed results.

The DGA (Dissolved Gases Analysis) technique has been widely using for fault diagnosis of the power transformers. Some electric power utility company establishes the criteria of DGA to improve reliability, because of difference of operation environment and design of power transformer. In this paper, we introduce intelligent diagnosis system for DGA result of KEPCO (Korea Electric Power Cooperation). This system can classify patterns type of gases ratio that frequently occurs in recent result of gases analysis using Fuzzy Inference. The classification of Patterns let us know that major causes of gases generation based on type of patterns. Finally, Neural Network based on patterns diagnose transformer. NN was trained using result data of DGA of actually faulted transformers recently. Result of intelligent diagnosis system is right well in comparison with actual inner inspection of transformers.
