  • A four-node plate finite element for the analysis of laminated composites which is developed using strain gradient notation is presented. The element is based on a first-order shear deformation theory and on the equivalent lamina assumption. Strains and stresses can be calculated at different points through the thickness of the plate. They are averaged values due to the equivalent lamina assumption. A shear correction factor is used as the transverse shear strain is taken to be constant over the plate thickness while its actual variation is parabolic. Strain gradient notation, which is physically interpretable, allows for the detailed a-priori analysis of the finite element model. The polynomial expansions are inspected and spurious terms responsible for modeling errors are identified in the shear strains polynomial expansions. The element is corrected by simply removing the spurious terms from the shear strains expansions. The element is implemented into a FORTRAN finite element code in two versions; namely, with and without spurious terms. Results are compared to show the effects of the spurious terms on the solutions. It is also shown that a refined mesh composed of corrected elements provides solutions which approximate very well the analytical solutions, validating the procedure.

  • This study aims to review the problem of East Asia notation and location in the world geography textbook. Major findings from this study are follows. First, Eastern Asia is used to denote the area where the Korea, China and Japan are located in world geography textbook, while Eastern Asia area covers Korea, China, Japan, Taiwan, and Mongolia on the map. Second, East Asia is appeared in textbook from the 2th national curriculum, as a cultural region shares same cultural tradition. It is recommended that East Asia might be the suitable place name to designate Northeast Asia and Southeast Asia, Northeast Asia can be use for the area where Korea, China, Japan, Taiwan and Mongolia are located.

  • This paper focuses components interactions which is important factor in designing software components. We classified several types of interaction between components and suggested appropriate graphical notation to extend UML and design process with extended method. Suggested notation and process was verified by practical experiment which is performed in travel agent component application. Representing interaction between components is not same to representing association between classes. UML in current version needs to be extended for representing this kind of components interaction. This research covers UML extension for components interaction and experiment for showing effectiveness.

  • UML is a standard language that models an analysis and design process in the development of an application system or components, CORBA, COM+, EJB and others are the techiniques that are realized reuse of components. After it is distinguished between reusable components and new components on the components development process and is developed, the developing cost of components or application system can be reduced and the components of superior in quality can be created. This paper defines the extended UML notation that needed in modeling of the products created from the development process of components. Also, this paper introduces a modeling of components and UML application method that needed in development of an auction system based on Web.

  • 안전필수 소프트웨어는 다양한 분야에 걸쳐 개발과 인증을 위한 표준들이 정의되어 있고, 대부분 프로세스 중심의 인증 방식을 채택하고 있다. 프로세스 중심의 인증 방식의 단점은 제품 소프트웨어의 검증 속성을 보장할 수 없고, 표준에 따라 관점과 관심 속성이 달라서 상호연관이 있는 속성사이의 관계를 기술하는데 적합하지 않다. 본 논문에서, 안전필수 소프트웨어의 표준들의 비교를 통해 특성을 살펴보고, 안전성과 보안 속성을 함께 갖는 안전필수 소프트웨어 개발을 위해, 보증 문서(assurance case) 구성을 목표 설정 표기법(goal structuring notation)으로 작성하고 결과를 고찰한다.

  • For a rule-based conversion of Hangout into the Roman alphabet rather than a word-for-word conversion, one must come up with a faultless model for the Korean standard pronunciation rules, which are the basis of the Romanization. It is on this foundation that the Korean-Roman alphabet conversion table can be created. For linguistic modeling using PetriNet, modeling boundary and notation of modeling can be defined. In order to describe PetriNet, which is a dynamic modeling tool, as a static one, one can model the standard Korean pronunciation rules and the Hangout-Roman alphabet notation by conversion into incident matrix Thus, this research attempts to develop a mathematical modeling tool for a natural language using PetriNet, and create a Korean-Roman alphabet conversion table.

Some Notational Problems of the translation of Japanese stops[k, t] and affricates[t s ,$t{\int}$] into Korean (일본어 파열음[k, t]과 파찰음[t s , $t{\int}$ 의 국어 표기상의 문제점)

  • The purpose of this paper is to show that the current notation of Japanese proper names in Korean has some problems. It cannot represent the different sounds between the voiced and voiceless. The purpose of this paper is also to give a more correct notation which is coherent and efficient. After introducing some general knowledge about the phonemes of Japanese language, I measured the Voice Onset Time of the stops[k, t] at the beginning, in the middle and at the end of a word, and compared the spectrogram of affricates with that of fricatives. In conclusion, Japanese voiceless [k, t ,$t{\int}$] should be written as [ㅋ,ㅌ,ㅊ] and voiced [g, d $d_3$] as [ㄱ,ㄷ,ㅈ] and the affricate[ts] as[ㅊ] in Korean.

  • Although various music composition programs for PCs have become commonplace, the reasons why people think it is hard to make music are the lack of experience with musical instruments, the lack of knowledge of music or composition, and the fear of learning MIDI software. In this paper, we propose an effective method to solve this problem by using plain text based method which makes it easy for the general people who do not know MIDI, have little experience of musical instruments, and cannot even read music to make their own music. As a result, many people who like music but have not been able to produce their own music may produce and distribute music, and collaborate with others to produce better quality music.

  • The purpose of this is to evaluate the contents through the anal us is of the merits and demerits, and its special quality of the Cutter-Sanborn Three-figure Author Table. table. The abstract of this study is as follows : With the results of the analysis of Cutter-Sanborn's Tabls, several advent-age were found in the area of enumerative-ordinal numbering system, mixed notation, and information retrieval. A defect is that each corporate author and serials and reference book's titles are difficult to be numbered, and there is serious diviation in percentages of the numbers assigned to each letter because each letter apportion rate was applied without any criteria. Such phenomenon decrease the effectiveness as author notation in several letters. The separation of headings are seriously unbalanced because the separation of heading is not consistent with actual publishing trends. This phenomenon made difficult individualization of materials in several letters.
