  • Meteorological Joint Frequency Function required indispensably in long-term air quality prediction models were discussed for practical application in Korea. The algorithm, proposed by Turner(l964), is processed with daily solar insolation and cloudiness and height basically using Pasquill's atmospheric stability classification method. In spite of its necessity and applicability, the computer program, called STAR(STability ARray), had some significant difficulties caused from the difference in meteorological data format between that of original U.S. version and Korean's. To cope with the problems, revised STAR program for Korean users were composed of followings; applicability in any site of Korea with regard to local solar angle modification; feasibility with both of data which observed by two classes of weather service centers; and examination on output format associated with prediction models which should be used.

  • No. 1 PL(Pickling Line) and No. 1 TCM(Tandem Cold Rolling Mill) at Pohang works started up in 1977 and have been operating successfully keeping high productivity for productivity thin gauge sheat such as BP, CR and silicon steel. On the other hand, customer's requirements of quality level are rasing higher continuously, so that Pohang works has combined and revamped No. 1 PL and No. 1 TCM in order to improve labor productivity, thickness accuracy and shape control capability, and so on in the period of 1977∼1999. This paper introduce the applied facilities, technologies and recent operations after revamping.

  • Eight species of Sargassum subgenus Bactrophycus section Halochloa and Repentia were collected from the coasts of Korea: Sargassum coreanum J. Agardh, Sargassum sagamianum Yendo, Sargassum micracanthum (Kützing) Endlicher, Sargassum macrocarpum C. Agardh, Sargassum autumnale Yoshida, Sargassum siliquastrum (Mertens ex Turner) C. Agardh, Sargassum serratifolium (C. Agardh) C. Agardh, Sargassum yezoense (Yamada) Yoshida et Konno. These species were investigated on morphological variations and geographical distributions in Korea. The valuable taxonomic characters between similar species of these section were discussed with special reference to types of holdfasts, shape of main branch, leaves and vesicles.

  • 이 글은 최근 인지언어학에서 기본적인 핵심이론 중의 하나로 자리잡고 있는 '정신공간 이론'(mental space theory)에 대한 이론적인 소개와 함께 의미구성에 있어서 중요한 개념의 하나인 '사상'(mappings)의 문제를 다루고자 한다. 1994년 이후 Fauconnier와 Fauconnier & Turner 등을 중심으로 진행되어 오고 있는 정신공간 이론에서는, 언어의 의미를 궁극적으로 인지적 공간들 사이의 상호관계가 언어로 '투사'(projection)된 것으로 간주한다. 그리고 기존의 근원영역과 목표영역 사이의 직접적이고 체계적인 사상, 이른바 '두 영역 모델'의 대안으로 '다공간 모델'을 제시하고 있다. 다공간 모델 속에는 '포괄공간'(generic space)과 '혼합공간'(blending space)이 설정되는데, 그 중에서 포괄공간은 근원공간과 목표공간의 모든 개념이나 추상적인 도식 등이 반영되어 있는 반면, 혼합공간은 실제의 다양한 개념적 혼합의 결과로 나타나며, 입력된 공간에서 나타나는 상응되는 부분들 사이의 연결을 활용하고 발전시키기 때문에 그 자체가 또 다른 혼합공간의 입력공간에서 일어나는 개념적 사상의 양상은 매우 다양할 뿐만 아니라 의미구성에 있어서도 중요한 역할을 한다. 이 글에서는 합성어와 같은 어휘적 측면은 물론, 일상의 문장 표현을 통해 나타나는 개념적 사상의 다양한 양상을 고찰하고자 한다.

  • The morphology of molluscan egg capsule is generally regarded as being species specific (Turner, 1992), and form and structure of the egg capsule reflect the degree of anatomical complexity of the reproductive organs (Fretter & Hian, 1984). Ceratostoma rorifluum and Ocinebrellus inornatum are common and widespread muricid species found throughout the Korean rocky and boulder shores, and Neptunnea constricta is found frequently from continental shelf of the eastern sea of Korea. In spite of their predominance along the Korean coasts, morphology of their eggs and egg capsules is unknown so far. The purpose of the present study, therefore, is to provide descriptions and illustrations for identifying egg capsules of the foregoing 3 stenoglossan gastropod species. (omitted)

  • Damaging winds, associated with a variety of weather phenomena, are frequently experienced in New Zealand. Observations and modelling of two recent extreme wind events; the Taranaki tornado outbreak of July 2007, and the Greymouth down-slope easterly wind storm of July 2008 are described in detail here. Post-event engineering damage surveys, rare for New Zealand, were done for these storms and the results are summarized here. Finally, the issue of sampling extreme wind events is raised and the need to include detailed numerical modelling analysis to understand wind gust climatologies at observing sites and extending these to wider regions is discussed.

  • 기계 부품을 설계함에 있어 솔리드 모델링 시스템의 사용을 골격으로 하는 CAD 시스템의 사용은 삼차원 모델링된 단일 물체에 대한 물성치(mass property)의 계산, FEM 해석을 위한 유한요소의 자동생성, 곡면에 대한 NC 공구경로(NC tool path)의 자동계산, 부품의 생산을 위한 가공 정보의 도출 등의 분야에 많은 도움을 주어 설계와 생산, 관리의 전 분야에 혁신적 효율화를 도모해주었다. 한편 이렇게 설계된 단품들은 대개의 경우 조립되어 조립체를 이루게 되고, 그 상태로 혹은 부품간에 상대운동을 하면서 원하는 기능을 구현하게 된다. 단품에 대해서처럼 이 과정에서도 CAD 시스템은 조립체의 삼차원 형상을 인식하고 필요한 정보를 제공해줌으로써 설계자에게 유용한 도구로 사용될 수 있는데 이를 조립체 모델링 시스템(Assembly Modeling System)이라 부르며, 현재에는 대부분의 솔리드 모델링 시스템에 그 기능이 채택되어 있다. 조립체 모델링에 관한 연구동향을 비교적 잘 정리한 문헌으로는 Turner와 Libardi의 것을 들 수 있다. 여기서는 이러한 조립체 모델링 시스템의 연구분야와 동향에 대해 또 나름으로의 시각으로 정리하였다.

  • We have shown in Part I [1] of this study that medical needle-stick injuries are causing serious health problems to healthcare personnel and other professionals that require the attention of healthcare and textile researchers to develop new protective systems. Responding to such need, a needle force measurement device that is capable of measuring dynamic forces experienced by medical needles during needle penetration through protective articles was developed and described in part I. This paper reports the results of evaluation of protective woven fabrics from high performance fibers and standard and bifid medical needles using the force measurement system. The woven fabrics varied in cover factor, number of layers, and orientation angle. Standard and bifid needles with different gap widths were used to evaluate the resistance of the fabric to needle penetration.

  • Turner and Penn (1) from UCL have proved that Visibility Graph Analysis (VGA) can be used as a more accurate method to predict the pedestrian distribution in building spaces. However, this methodology neglects certain elements that are of special influence on pedestrian distribution in buildings, especially the entrances and exits. Based on Space Syntax, this dissertation improves on the traditional method of Visibility Graph Analysis, using three shopping centers in Shenzhen as examples, attempts to explore a new parameter - "attenuation index of pedestrians at the entrances and exits" - using relevant data of the entrances and exits of the three cases, and combines it with traditional VGA analysis through weighted calculation, in order to provide more accurate predictions of pedestrian patterns in shopping centers.

  • A 'TEXT' is a basic unit of culture. It is also the whole of culture organization which is generalizing a culture. Literary texts which are reflection of the culture could be understood as historical discourse. This thesis which is based on the 'Semiotic theory', 'Victor Turner's Performance theory', and Sung Man Lee's 'Information Model', classified the type of meaning to explain how to communicate the meaning of thing which were described in novels, for examples, background, dress, dialogue, era, etc. An interpreter (reader) should understand the culture described in novels to clarify the ambiguous significance. An interpretative theory of symbolic meaning described in text was presented in this thesis, and it was applied to analysis Myung Hee Choi's novel, 'Honbul'.
