  • The article discusses the dead reckoning of the traveled path based on the analysis of the video data stream coming from the optoelectronic surveillance devices; the use of relief data makes it possible to partially compensate for the shortcomings of the first method. Using the overlap of the photo-video data stream, the terrain is restored. Comparison with a digital terrain model allows the location of the aircraft to be determined; the use of digital images of the terrain also allows you to determine the coordinates of the location and orientation by comparing the current view information. This method provides high accuracy in determining the absolute coordinates even in the absence of relief. It also allows you to find the absolute position of the camera, even when its approximate coordinates are not known at all.

  • Beckett's life-long struggling with death may be illuminated in terms of the Western tradition of thanatology as well as Philippe Ariès's anthropological classification of death. Among the Western tradition, Beckett's oeuvre incarnates memento mori, timor mori, nihilism, theatrum mundi, life as afterlife, and the transsubstantiation of the self. Among the five views of death Ariès suggests, Beckett appears to foreground the death of the self and the invisible dirty death. In a world devoid of transcendental Signified, Beckett's resident is "a poor player/That struts and frets his hour upon the stage." Our contemporary vision of death is dominated by the dirty death and timor mori resurrected from the cultural icon of danse macabre in the late Mediaeval age as vividly dramatized in W;t by Margaret Edson. Beckett stands in no man's land: Lucky complains of divine aphathia as well as scopes at the possibility of God's existence like Hamm. Beckett's way of getting out of the dilemma is laughing a mirthless and dianoetic laugher. To bourgeois class who shudder at the sight of Grim Death after forgettable years of indulgence and addiction to capitalist consumption, Beckett seems to preach, your life is a death-in-life, you are not born yet until you are baptized with existential awakening as Gregor Samsa in Kafka's Verwandlung, or Tolstoy in Confession.

  • 본 연구는 기호학적 분석과 해석을 통해 아파트브랜드 명명(命名)에 담긴 의미와 가치를 살피고, 브랜드가 지향하는 조경적 관점의 설득 메시지가 무엇인가를 밝히고자 시도되었다. 명명 조어분석 결과, 조합과 접합 그리고 혼성방식의 경향이 강한데, 이는 주거문화의 다양한 가치를 담기 위한 시도로 판단된다. 명명 발상법은 문자의 상징성 강조 방식이 강하며, 다의적 메시지를 전달하고자 하는 중의법적 경향과 건물에 인격을 부여하기 위한 의인화, 고유어 및 한자를 적절히 섞어 이용함으로써 자연과 인간의 조화 및 전통적 주거관을 현대적 감각으로 되살리고자 하는 실험성도 동시에 발견된다. 어휘소의 빈도 분석 결과, ville, nature, beauty(미(美)), human, park, hi, green, palace(궁(宮)), nobility, centre(tra) 등의 순으로 설득언어의 등장 비중이 높음을 알 수 있는데, 이는 대부분 조경 및 전망, 자연성 그리고 품격 등을 설명하는 어휘소로 판단된다. 또한 아파트브랜드 포지셔닝 등 기존 연구동향을 바탕으로 한 분석틀에 의한 어휘소 유형화 결과, 국내 아파트브랜드의 지향점과 가치를 좌우하는 가장 비중 있는 외적 개념 축은 '환경지향성'과 '감성지향성'이며, 내부적으로 '기능지향적' 특성이 강화되는 추세로 볼 수 있다. 또한 '환경지향성'을 표출하는 대표적 설득언어이자 브랜드 어휘소의 순위가 정원 및 공원, 전망 그리고 자연성 등임을 볼 때 '조경적 설득 메시지'가 브랜드 명명에 팽배되어 있음을 엿볼 수 있다. 또한 palace, nobility, class를 주요 어휘소로 하는 '품격축'과 human I, you 등을 어휘소로 하는 '자부심축' 등의 감성지향적 설득언어 역시 브랜드의 차별화와 고급화를 선도하는 중요 가치개념이자 설득언어로 활용되고 있다. 더불어 환경지향적 관점으로 유형화한 전망축의 어휘소 중 hi, hill, tower, view, mark, heights 등의 어휘소는 주상복합아파트 등 조망을 주요 가치개념으로 한 초고층아파트가 지향 트렌드와 중복되고 있음을 비추어볼 때, 당분간 고층지향적 설득언어 역시 국내 아파트브랜드의 동향을 지배하는 요인이 될 것으로 예견된다.

  • Purpose : This study was performed to determine the proper reference line for taking axial computed tomograms from which the good cross-sectional views can be reformatted by multiplanar reconstruction. Methods : Three dry mandibles with implanted gutta percha cones in the extracted socket were scanned axially according to 6 reference lines of 2 mandibular positions with computed tomogram Hitachi W550. The accuracy of measurements of the lengths of implanted gutta perch a cones in the each cross-sectional view reformatted from axial computed tomogram by multiplanar reconstruction was evaluated. Results: The difference between the measurements and the real length of implant was smallest in the bucco-lingual views reformatted from the axial views scanned according to the reference line of group V-a. The smaller the angle difference between reference line and occlusal line was, the smaller the difference between the measurements in the bucco-lingual views reformatted from axial views and the real length of implant. The majority of measured widths of implants in the bucco-lingually reformatted views were larger than the actual values. Conclusions : When the mandible is inclined within the limitation of gantry angle and scanned with the reference line coincident with occlusal plane, the bucco-lingual view can be reformatted without deformation of images from the axially scanned images.

  • This study examines the children's wear purchasing behavior of younger generation women (the missy group) and in the new-silver generation (retired). The data collected in the study were examined with a view to establish effective marketing strategies within the children's wear market, a market where the age and characteristics of the actual purchasers of the products have become more diverse. A descriptive survey method using a self-administered questionnaire was employed. The sample consisted of 398 females between the ages of 28 and 64 residing in Seoul and the Gyeonggi-do area. Data collected were analyzed by frequency, t-test, ANOVA, factor analysis, cluster analysis, and Cronbach's alpha coefficients. Respondents were classified into 4 groups by their clothes shopping orientation: conformable/brand conscious purchasing type, planned purchasing/enjoy shopping type, store/brand loyal impulse-oriented type, and dependent/low shopping interest type. There were differences between the missy and the new- silver generations under consideration. It is clear from the study that, even though some individuals of the missy group and of new-silver group belonged to the same shopping orientation type, individuals still showed differences with regard to children's wear purchasing behavior.

  • Architectural color would be understood as a essential tool to be reflected the architect's value criteria, thinking process and the specific methodology. This study was established the characteristics of color use correlated with Eisenman's architectural features based on his point of view. At first, it could be organized with data and use the color in view points with the becomming process. Especially it would be expressed the color as a trace of unsynchronized formation. Second, it was introduced the color by graphics engaged with form, to be expressed the dividing, folding, reiteration for deliver of escape from graphic thinking process. Third, it was analyzed to be imported the color to have a multi-lateral space experience in center of user's space recognition and behavior by introduction of color. Finally, it could be inducted the consistent color by viewpoint of interfacial between interior and exterior environment, communicated with strong meaning by conversion from interior elements to color from these processes. A characteristics of Eisenman's architecture color is reflected his thinking process in architecture color as it is and can be understand of 'becomming process use of color' as a tool that is corresponded in form creation. Specially, it would be kept continuous viewpoint of interior and exterior space, giving user color as a viewpoint of linking space, enable many-sidedness experiences through space.

  • The purpose of this thesis is to analyse modem urbanization process and the morphological transformation of the urban tissues in Kunsan between the you 1899 and 2001, The method of this study is to investigate the transformation process of morphological elements such as plot structure, building layout, building facades, land use, exterior space structure and their use, with actual field surveys, the analysis of land registration maps in 1912, and various topological map. Morphological analysis on modern Kunsan is progressed by three steps-typo-morphological analysis of urban tissue in old-town area, interpretation of morphological process, and transformation process, of morphological structure in Japanese concession in view of plots system. As a result, it is found that there is cyclical relationship among the morphological transformation processes of morphological elements, plots, buildings, land-uses, and access space to buildings. From the view of town plan change, the period of restoration of war damage in 1950s and compressive growing period in 1960s have important meaning in the morphological process of old-town area. Particularly the first building plan and layout type together with plot form and structure is acted as the main factor to decide the subsequent plot transformation system, exterior space system and the particular streetscape in Kunsan.

  • A portable clip-type pulsimeter equipped with a magnetic sensing Hall device has been developed to raise the accuracy of oriental disease diagnosis and therapy by convergence of magnetism and oriental medicine. To improve accuracy and reliability of conventional pulsimeter due to subjective analysis of the pulse wave and measuring position dependency of the arterial pulse sensor, the fuzzy algorithm was applied to analyze the strong- and weak-pulse wave symptom. Optimal time for electronic acupuncture was calculated using fuzzy rules and interference were drawn from objective data in view of pre-treatment. Moreover, the electrical characteristics of the pain parts that respond to acupuncture point were applied in view of post-treatment to propose the scientific pulse wave algorithm and simulation experiment.
