  • The purpose of this research is to improve exhibition effectiveness by implementing hands-on exhibition technique that best provides adults with cultural resting place and children with outdoor education which simply supports school curriculum. By completing this research, the museum of natural history will become defined innovative as a place that enables people actively develop creativity For this sake, some of domestic natural science museums were selected as the samples in this study, such as Seodaemun of Natural History, Incheon Standing Science Pavilion and Daejeon National Science Museum, Which all produce experience-based exhibition in relatively brisk manner. First of all, this study attempted to identify the traffic line and behavioral characteristics of spectators who used experience-oriented exhibition through follow-up and observational study Then it divided samples into adults and children group to compare and analyze the ratio of using exhibitions, the ratio of spectators and the sojourn time according to the type of experience-oriented exhibitions. In addition, this study attempted to collect available data about spectators who were in conversation with one another on the other hand, it also attempted to determine any effects on using experience-based exhibition by performing a questionnaire survey, so that it might set up an index for behavioral characteristics the spectators who visit such exhibition.

Beyond Alan Colquhoun's Architectural Hermeneutics of Tradition - from 'conceptural displacement of the past' to 'the reactivation of the past'- (앨런 코쿤(Ahin Colquhoun)의 전통건축 해석학을 넘어서 -'과거를 개념으로 대체(displacement)하기'에서 '과거를 재활성화(reactivation) 하기'로-)

  • The first aim of this paper is to investigate and analyze Alan Colquhoun's architectural hermeneutics of tradition, 'conceptual displacement of the past.' The second aim is to overcome the limit of it, and to suggest new architectural hermeneutics of tradition, 'the reactivation of the past.' The architectural work is reduced by Colquhoun to typology or arbitrary language because he believes that without arbitrary language natural language is not able to work effectively. However, he ignores that two languages cannot be separable. When they are separated the key to natural language is understood to be an unverifiable similarity between a sense perception and its correspondence in the architectural object, while the key to arbitrary language becomes mere artificial agreement on the value and function of the linguistic sign. Therefore, natural language is appropriate only when it permits spontaneous combinations of sensory data within complex structures which emerge from, and support, complex human interaction and communication(the shining of the world and of the possibility of creative being in each individual thing). Only when architecture is translated into this kind of language, can it reactivate the world's past, and become poetic.

  • In the present investigation, experiments on the melting of a phase change material were performed to research heat transfer phenomena generated by means of conduction and natural convection in the vertical tube at inward melting. The phase change material used in the experiments is 99 percent pure n-Docosane paraffin which is measured melting temperature of $42.5^{\circ}C$, latent heat of 37.5 cal/g, heat conductivity of $0.1505W/m^{\circ}C$. Experiments were performed both in the no-subcooling which is initiating it at melting temperature of phase change material, and in the subcooling which means to initiate it under melting temperature of phase change material, in order to compare and investigate the horizontal temperature history, vertical temperature history, ratio of melting and melted mass, figure of the melting front in the vertical tube. In the experimental results, heat transfer from tube wall to phase change material were due to conduction at early stage and due to natural convection with the passage of time, and then occurred melting downward from surface by volumetric expansion. Natural convection affects temperature distribution in the tube, ratio of melting and melted mass, figure of the melting front and then progress rapidly in case of nosubcooling compared to subcooling.
