  • 약 4억만년 전에 출현하였을 거미류의 진화를 생태학적인 측면에서 수중생활, 낙엽층 속에서의 생활, 토양틈사이에서의 생활, 땅속에서의 생활, 동굴에서의 생활, 지표위에서의 배회생활, 공중에서 거미그물을 치면서의 생활하는 과정과 그에 속하는 거미류의 종류와 형태변화 등에 관해 진화적인 측면에서 조사연구하여 정리 보고하고자 한다. 우리나라에 존재하지 않는 거미과명의 국명은 Kim (1998c)의 방식에 따랐다.

  • Quantity Surveying Profession is a new breed with a history of only less than seven years in S. Korea' s Construction Industry. In this paper, the research aims to investigate the background of the market entrance of this profession in Korean Construction Industry, and the current market direction and future market demands. The research concludes that climate changes in Real Estate markets in relation to Project Financing practices caused by economic crisis of late 1997's, enabled the UK originated QSP sustainable in S. Korea. Moreover it was pointed out that the services of QSP current available in S. Korea's market attributed the different aspect compared to traditional quantity surveying services prevailed in UK. Finally it was apparent that the evolutional direction of the future quantity surveying market in S. Korea is most likely toward multidisciplinary skilled services profession processing not only broader architectural knowledges but cost consciousness, specialty in construction costs and construction contract aspects and transparency in ethical manner.

  • The contemporary South Korean landscape is characterised by a massive display of modern apartment buildings. They are omnipresent in their monotonous manifestation and represent the dream of the Korean population. Serial mass housing is a typology that has had a great diffusion all over the world, but how has modern housing developed in South Korea? To this end, what are the resulting local adaptations?. This paper retraces these key evolutional aspects. Methodologically, it draws on a scholarly literature review as well as on-site photographic surveys, developed in connection with an educational program at the Korea Tech University. The result is the analysis of both the urban and architectural transformation from the early modernisation period to the present condition of contemporary housing. A historical background introduces Korean traditional urban houses, to be used as a context to describe the contemporary modern city that has developed since the 1960s. The main emphasis is then placed on the urbanisation process that fully matured during the 1980s together with a focus on the mass housing typology as the main pivot in the urban transformation. Finally, the paper will draw a parallel between modern Western theories and Korean applications.

  • Reconstructive surgery in the management of head and neck cancer has evolved to include structure-specific approaches in which organ-specific treatment algorithms help optimize outcomes. Tongue cancer management and reconstruction are surgical challenges for which well-executed reconstructive plans should be completed promptly to avoid delaying any subsequently planned oncologic treatment. Crucial considerations in tongue cancer resection are the significant functional morbidity associated with surgical defects, particularly in terms of speech and swallowing, and the consequent negative impact on patients' quality of life. With the evolution of microsurgical techniques and the development of the perforator flap concept, flap options can be tailored to the characteristics of various tongue defects. This has allowed the implementation of pliable flaps that can help restore tongue mobility and yield subsequent functional outcomes. Using an evolutional framework, we present this series of reviews related to tongue reconstruction. The first part of the review summarizes flap options and flap-related factors, such as volume and tissue characteristics. Related functional aspects are also presented, including tongue mobility, speech, and swallowing, as well as ways to evaluate and optimize these outcomes.

  • Interests in the field of rapid methods and automation in microbiology have been growing steadily on an international scale in recent years. International meetings concerned this problem have been held in elsewhere in the world countries since the past twenty years. But, unfortunately in the field of microbial examination in food hygiene, this problem have not yet been developed so much as in the field of clinical microbiology. Today, I would like to introduce you here present aspects of rapid and automation technologies, those which are manly carrying in milk and meats industries. My illustration will be given recent improved technologies using automatic apparatus and instruments along with process of microbial count procedure. Recent direct microbiological counting system (ChemeScan \ulcorner) as real time ultrasensitive analysis created by Cheminex Ltd., France is now most evolutional instrument to provide direct microbial counts, down to one cell, within 30 minutes. The results from these evaluations how a good correlation between the ChemScan system and the standard plate count method. This system will be successful application for not only in the field of pharmacology but also food microbiology. In addition, current identification of microbes by sophisticated instruments suitable for food microbiology, one of which Biology is manual system (BIOLOG\ulcorner), provides reference-level capability at a modes price. For the manual system, the color reactions in the microplate are read by eye and manually keyed into personal computer. Species identification appears on the computer screen within seconds, along with biotype patterns, a list of closely related species, and other useful statistics. In present this is useful application for microbial ecology and epidemiological survey. RiboPrinter system newly produced by DuPont is now focusing among microbiologists in the world, and is one of the biggest microbial characterization system using a DNA-based approach. The technology analyzer is bacterial culture for its genetic fingerprint or riboprint pattern. Finally Bio-cellTracer system for automatic measurement of fungal growth and Fukitori-Maseter, a Surface Hygiene Monitoring Kit by using swabe procedure in food processing environment are briefly illustrated in this presentation.
