  • In GIS area, many line simplification algorithms are studied among generalization methods used for making the building data in the form of digital map from the original line data. On the other hand, there are few studies on the simplification algorithm considering the drawing rules of the digital map in Korea. In this paper, the line simplification algorithm based on the drawing rules is proposed as the methodology to create or update the building data of digital map by extracting the building outline from the CAD data used in construction. To confirm the usefulness of the algorithm, this algorithm and four other effective and general line simplification algorithms (e.g., Douglas-Peucker algorithm) are applied to the same building outlines. Then, the five algorithms are compared on five criteria, the satisfaction degree of the drawing rules, shape similarity, the change rate of the number of points, total length of lines, and the area of polygon. As a result, the proposed algorithm shows the 100% of satisfaction degree to the drawing rules. Also, there is little loss in four other mentioned criteria. Thus, the proposed algorithm in this paper is judged to be effective in updating the building data in digital map with construction drawings.

  • Latest modernism shows general idea of phenomenal space through nature of place motility and experience sinceded from standard form and it has general idea of space. therefore this study presents the tension and the relaxation as a method looking for spatal change and value that in spatial experience. For the analysis of work the Conference Pavillon of Tadoa Ando in the furniture company in Vitra Fire Station of Zaha Hidid is analyzed in spatial experence. As the result the result the systematic straight mixture that has a superrimotion with long retangle which the space acts independently and is shown in the drawing of absolutism is formed and collapses theregularity of construction form by decomposition annexation mixing collision and ambivalence. The spatial experiance in this unstable form changes the grade of rank of space by opposite phenomenon by the change of spatial flowing the disorted and vague space that is occurred by superrimotion which has no direction and change of lirht and place and consolidates dynamic strain makes possible to construct against the gravity. And it also creates experienced space thatis reaxed with maintenance of organization of unity harmony, and stsbility.

  • While prior work has conducted individuals' password security behavior, there is a relatively neglect to examine individuals' affect and feelings of password fatigue in password change context. Therefore, this study explicated individuals' affective response to the feelings of password fatigue by drawing on several theoretical lens. Survey data collected from 267 users were used to test the model using partial least square analysis. This study found that feelings of password fatigue positively affected the negative password fatigue-induced affect, and also both the feelings of password fatigue and the negative password fatigue-induced affect were negatively related to attitude toward changing passwords, which in turn, leads to the intention to change passwords. Furthermore, this study found that shadow work recognition negatively moderated the relationship between attitude and behavioral intention. This study could offer a new theoretical perspective to understand an individual's security behavior and provide empirical evidences for practitioners in charge of IT security in organizations.

  • The effects of air-gap distance on properties of cellulose fiber spun from the 6 wt% solution of cellulose in monohydrate N-methylmorpholine N-oxide (NMMO) were investigated. The diameter of fiber spun was drastically reduced in 10 cm of air-gap distance at fixed drawing speed, however, no great change was observed beyond 40 cm. As the distance lengthened, the Cellulose II structure was first appeared and followed by Cellulose II and IV mixed morphology. Also the degree of crystallinity and the size of crystals were tending to decrease.

  • Classification and Coding(C&C) systems as a core of design information management have been accomplished by many studies in terms of design and manufacturing attribute based on Group Technology. Those are very difficult to apply in make-to-order(MTO) manufacturing because the environment of MTO has various characteristics of product, many licensors, engineering change, insufficiency of integrated management system for codes and so on. This paper presents a suitable C&C system to MTO manufacturing which consider management level and drawing.

  • 1950년 Poly(ethylene terephthalate)(이하 PET)의 상업화 이후 Poly(trimethylene terephthalate)(이하 PTT)는 동종의 Poly(methylene terephthalate)계열의 고분자 중에서 Poly(butylene terephthalate) (이하 PBT)와 함께 최근 가장 주목받는 섬유 중의 하나이다. PTT 섬유는 얼마 전까지만 해도 주원료인 1,3-propanediol(이하 PDO)의 가격이 너무 높아 지난 60년 간 상업화 및 학문적 연구가 거의 이루어지지 않다가 최근 미국의 Shell사와 독일의 Degussa(미국의 Dupont)에 의해 PDO가 대량 생산되면서 상업화에 대한 연구가 활발히 이루어지고 있다. (중략)

  • The trend towards employee involvement (EI) has redefined the employer-employee relationship and, for many organizations, has brought about a fundamental change in organizational performance. This paper begins with a review of EI concepts and typologies. It goes on to elaborate need for the adoption of EI practices and discuss the factors affecting the adoption. The main theme of the quality management (QM) literature will then be presented addressing its concepts, principles and elements. Drawing on the theoretical and practitioners' perspectives, the paper also discusses the significance of integrating EI/QM practices to sustain organizational performance improvement.

  • Ray drawing in geometrical optics is an effective method for visible imagery of light. In this study, we developed peer instruction materials for in-service teachers' training concepts on the refraction of light including drawing rays. And then we applied these programs to 29 pre-service teachers and 21 in-service primary teachers and evaluated the degree of conceptual change in correct points from the pretest and the post one. As a result of pretesting, in spite of experiences for learning this topic in elementary and secondary education courses, most participants in the study did not well understand the path of refracted light before instructions. However, the result of post testing after the application of peer instruction materials shows that they have practiced ray drawing, which is helping visible imagery. Accordingly, in learning geometrical optics, we suggest that peer instruction with ray drawing activity for teachers' training program would be effective. We also suggest that similar approaches would be applied to other context.

  • In this paper, we present a new algorithm which imitate real pencil strokes. The purpose of research on NPR(Non-Photorealistic Rendering) is simulating automatically manmade artistic expressions such as pen-and-ink illustrations, watercolor paintings, pencil sketches and pastel drawings with computers. Recently, there has been a great deal of research works on NPR. One of them is researching in pencil illustration methods for NPR, and a lot of researchers have investigated into the LIC(Linear Integral Convolution) techniques which would change the initial images into the output images by directional vector field images for generating effects of pencil. However, the LIC techniques can not be applied to real-time drawing tools because they are post processing techniques. This paper presents a real-time pencil strokes algorithm which is based on an observation of how pencils(from 6B to 6H) draw lines. Although this algorithm using some pencil variables and noise generation is simple, it is fast and also can draw real-time pencil strokes similar to real manmade pencil strokes in a GUI drawing tool.
