It is well known that there is an inverse relationship between the strength of Indian summer monsoon Rainfall (ISMR) and extent of Eurasian snow cover/depth in the preceding season. Tibetan snow cover/depth also affects the Asian monsoon rainy season largely. The positive correlation between Tibetan sensible heat flux and southeast Asian rainfall suggest an inverse relationship between Tibetan snow cover and southeast Asian rainfall. Developments in Regional Climate Models suggest that the effect of Tibetan snow on the ISMR can be well studied by Limited Area Models (LAMs). LAMs are used for regional climate studies and operational weather forecast of several hours to 3 days in future. The Eta model developed by the National Center for Environmental Prediction (NCEP), the Fifth-Generation NCAR/Penn State Mesoscale Model (MM5) and Regional Climate Model (RegCM) have been used for weather prediction as well as for the study of present-day climate and variability over different parts of the world. Regional Climate Model (RegCM3) has been widely . used for various mesoscale studies. However, it has not been tested to study the characteristics of circulation features and associated rainfall over India so far. In the present study, Regional Climate Model (RegCM-3) has been integrated from 1 st April to 30th September for the years 1993-1996 and monthly mean monsoon circulation features and rainfall simulated by the model at 55km resolution have been studied for the Indian summer monsoon season. Characteristics of wind at 850hPa and 200hPa, temperature at 500hPa, surface pressure and rainfall simulated by the model have been examined for two convective schemes such as Kuo and Grell with Arakawa-Schubert as the closure scheme, Model simulated monsoon circulation features have been compared with those of NCEP/NCAR reanalyzed fields and the rainfall with those of India Meteorological Department (IMD) observational rainfall datasets, Comparisons of wind and temperature fields show that Grell scheme is closer to the NCEP/NCAR reanalysis, The influence of Tibetan snowdepth in spring season on the summer monsoon circulation features and subsequent rainfall over India have been examined. For such sensitivity experiment, NIMBUS-7 SMMR snowdepth data have been used as a boundary condition in the RegCM3, Model simulation indicates that ISMR is reduced by 30% when 10cm of snow has been introduced over Tibetan region in the month of previous April. The existence of Tibetan snow in RegCM3 also indicates weak lower level monsoon westerlies and upper level easterlies.

This study has been made to examine the symbolic meaning of our traditional costume colours based on the theory of yin-yang Wu-hsing the interaction of yin and yang with the rotation of the five agents wood firt earth metal and waters. Presenting the spirt and the life of our race the costume culture has been keep-ing its own systematic symbol. Being sensible the colour has to be under-stood as the colour sense therefore the cos-tume colour has begun to have the symbolic meaning with the feeling or the mental value. According to the theory of yin-yang wu-hsing the costume colour has presented our racial sprit way of thinking and way of life for a long time and it has become the tra-ditional culture at last. Based on the doctrine of cosmic harmony through the motion of yin and yang or the passive and active elements are their five agents form the material force of everything. The order of nature has its counterpart in five symbolic costume colours wood-blue ; fire-red: earth-yellow; metal-white: water-black. The five colours are called the primary colours. which produce the next compound colours. Accepted in the social system as well as the social stats the costume colour has set up systematically. The theory of Yin-yang Wu-hsing has given the five colours the symbolic meanings and its mainstream has been the function of Sangsaeng and Sangeuk which are genera-ted by the power of virture. The former is mu-tually beneficial while the latter destructive. The colour as a costume colour has been made distinction between the colour of the up-per classes and the colour of the middle and lower classes and the specific colour has presented the symbolic meanings. The yeollow the red and the purple have been regarded as the colour of king queen and upper classes Being the colour recognition the costume colour has been established by the society and the race generally Implied the spiritual elements the colour recognition could select the lucky colour in accordance with one's des-tiny. Besides the colour recognition has begun to appear as the racial costumes to protect the society and to pray for good fortune. According to the theory of Yin-yang Wu-hsing the costume colour has been forming through our long history and has become our costume culture. Therefore the colour of the costume has signified not only the colour sense but also the important symbolic meanings.

The importance of energy saving technology for managing greenhouse was recently highlighted. For practical use of energy in greenhouse, it is necessary to simulate energy flow precisely and estimate heating/cooling loads of greenhouse. So the main purpose of this study was to develope and to validate greenhouse energy model and to estimate annual/maximum energy loads using Building Energy Simulation (BES). Field experiments were carried out in a multi-span plastic-film greenhouse in Jeju Island ($33.2^{\circ}N$, $126.3^{\circ}E$) for 2 months. To develop energy model of the greenhouse, a set of sensors was used to measure the greenhouse microclimate such as air temperature, humidity, leaf temperature, solar radiation, carbon dioxide concentration and so on. Moreover, characteristic length of plant leaf, leaf area index and diffuse non-interceptance were utilized to calculate sensible and latent heat exchange of plant. The internal temperature of greenhouse was compared to validate the greenhouse energy model. Developed model provided a good estimation for the internal temperature throughout the experiments period (coefficients of determination > 0.85, index of agreement > 0.92). After the model validation, we used last 10 years weather data to calculate energy loads of greenhouse according to growth stage of greenhouse crop. The tendency of heating/cooling loads change was depends on external weather condition and optimal temperature for growing crops at each stage. In addition, maximum heating/cooling loads of reference greenhouse were estimated to 644,014 and $756,456kJ{\cdot}hr^{-1}$, respectively.

Senior citizens' new life style has appeared according to the massive retirement of the baby boom generation since 2010. Consequently, Senior Welfare Centers, the provider of elderly leisure programs, has been asked for the programs and spaces which are able to meet the changing life style of the elderly. This study focuses on the survey for current status of leisure programs in accordance with the changing life style and on the investigation for sensible usage of space in senior welfare centers in Gwangju Metropolitan city. The result shows the portion of the programs which every center provides is quite different according to the life style. The program types for challenge and utility are provided 192 times a week and the program types for health and sociality 133 times a week. Both types shows high frequency of supply and use of the program especially 85 times of information-oriented education, 64 times of musical instruments, and 42 times of foreign language are supplied vividly. On the contrary, the program types for fashion and self-management and the program types for volunteer work and achievement are insufficient, so It should be reconsidered to establish the programs and to supply the space for the program from now on. The current status for spatial usage shows that most of the centers share a space for several programs. It means that the space of the Senior Welfare Center is limited and various programs should be run in the narrow space. High frequency programs like the program types for challenge and utility secure sufficient spaces not to miscarry the use for the programs. The center of case B has well equipped and large space and provides proper space for each programs to meet the demand of the senior citizens. Like these, Senior Welfare Centers in Gwangju Metropolitan city have supported Senior citizens' Life Style by supplying various leisure programs to meet the demand for it. This research could be used as the basis for the programs about the spatial utilization in accordance with various future life style of Senior citizens'.

The technologies related to the development of cultural contents we known as cultural technology (CT). CT should evolve with the changes in the cultural contents market. Currently there are five major trends in cultural market change. First, consumers are seeking more and more sensible quality from products. Second, consumers are becoming less sensitive to the cognitive quality of products. Third, consumers demand more than what contemporary technology can offer. Fourth, as the cultural products market grows, the goal of content developments has shifted from producing a 'big hit product' to producing a product which will maintain market share. Fifth, cultural products are diversifying. All these trends make the cultural products developer's job more challenging. Sensation & emotional engineering (SE engineering) can be a useful tool for cultural products developers. SE engineering is a study of the somatic sensation and the aesthetic sensation for both fundamentals and applications aspects. By quantifying the physiological and psychological responses of consumers, it studies the physical nature of stimulants, providing basic knowledge for future applications and industrialization. One widely spread myth is that a sparkling idea from a talented individual will make a difference in the cultural products industry. The careful examinations of many successful cultural products prove this is not correct. Many successful cultural products are the result of a substantial amount of investment and employment of well polished marketing technology. A scientific approach is highly required for this matter and the SE engineering is an answer

In order to manage a large number of devices connected to the Internet of Things (IoT), the Internet Engineering Task Force (IETF) proposed the IPv6 Routing Protocol for Low Power and Lossy Networks (RPL). The route of the RPL network is generated through the use of an Objective Function (OF) that is suitable for the service that is required for the IoT network. Since the route of the RPL network is conventionally simply chosen only by considering the link quality between the nodes, it is sensible to seek an OF that can also provide better Quality of Service (QoS). In previous studies, the end-to-end delay might possibly be sub-optimal because they only deal with problems related to the reduction of energy consumption and not to the link quality on the path to the sink node. In this study, we propose a scheme that reduces the end-to-end delay but also gives full consideration to both the quality on the entire route to the destination and to the expected lifetime of nodes with bottlenecks from heaped traffic. Weighting factors for the proposed scheme are chosen by experiments and the proposed scheme can reduce the end-to-end delay and the energy consumption of previous studies by 20.8% and 10.5%, respectively.

In underground spaces including nuclear waste repository, prediction of air quantity, temperature/humidity and pollutant concentration is utmost important for space construction and management during the normal state as well as for determining the measures in emergency cases such as underground fires. This study aims at developing a model for underground space environment which has capabilities to take into account the effects of autocompression for the natural ventilation head calculation, to find the optimal location and size of fans and regulators, to predict the temperature and humidity by calculating the convective heat transfer coefficient and the sensible and latent heat transfer rates, and to estimate the pollutant levels throughout the network. The temperature/humidity prediction model was applied to a military storage underground space and the relative differences of dry and wet temperatures were 1.5 ~ 2.9% and 0.6 ~ 6.1%, respectively. The convection-based pollutant transport model was applied to two different vehicle tunnels. Coefficients of turbulent diffusion due to the atmospheric turbulence were found to be 9.78 and 17.35$m^2$/s, but measurements of smoke and CO concentrations in a tunnel with high traffic density and under operation of ventilation equipment showed relative differences of 5.88 and 6.62% compared with estimates from the convection-based model. These findings indicate convection is the governing mechanism for pollutant diffusion in most of the tunnel-type spaces.

With entering the 21st century, modern people's dark inside and panic are emerging as the talking point on the theater stage. Even in the field of stage costume, the necessity of a research is being demanded through analyzing on psychological anguish and structure of characters. Accordingly, this study aims to allow the stage costume design to be expressed a human being's Doppelg$\ddot{a}$nger Image, which was elicited through analyzing a work of the play titled Le Grand C$\acute{e}$r$\acute{e}$monial by a playwriter Fernando Arrabal, who draws the conflictory and contradictory duplicity, which positions in a human being's deep inside by having chaos as catalyst. A research subject is 'Le Grand C$\acute{e}$r$\acute{e}$monial,' which was staged as the winter performance in commemoration of the 50th anniversary for the foundation of Dept. of Theater, Chung-Ang Univ. in November 2009. Psychology of characters in a play, which varies dimensionally, could be delivered, as nonverbal element called costume, by applying costume design of Cavanoza, Syl, Nice to Doppelg$\ddot{a}$nger Image such as Innocence vs Cruelty, Purity vs Superficiality and Restraint vs Freedom, which were elicited through analyzing characters. Through this study, the costume, which was expressed by visualizing a human being's Doppelg$\ddot{a}$nger Image, could be known to function as important dramatic factor of allowing character's psychology to be understood through costume as well as functioning as visual and sensible language, which is important for communication with the audience. A research on costume design, which reflects a character's complex inside, is expected to be likely continued through in-depth analysis on a playwriter's intention and on the appearing characters at the current point of time when an active research is being performed on stage costume in the wake of this study.

This study is what tried to examine the importance of material in industrial design. Then, if planning is to start of product design, the use of material is the last step to complete design. Design material has existed from the time before mankind were born, and the new material which is useful for human beings is developing rapidly. It is no exaggeration to say that our environment is the aggregation of material which was surrounded with us. Then, material has the timely, spatial and cultural feature as well as physical feature. Besides, all sorts of functions of communicating information are being contained in accordance with the character of material. The outside surface of material has the function to develop the sense organ of human beings. This study examines 4 kinds of cultural features in design materials and shown by findings is as follows : Rrst is the technical progressivity to lead new Design form. Second is the symbolic nature to perform the communication function. Third is the sensible attribute to develop surface effect of Design material. Fourth is the future-oriented nature to convince the future such as new material and technology etc. Thus, so as to perform the competitive product design, it is important to grasp the harmony between material and design, structure and processing, and the substantial meaning that the material has and apply them properly, above all. Because the discovery of material will be the measure to forecast future design.

Both competent authorities and private entrepreneurs face plenty of risks when negotiating BTO(Build Transfer Operation) methods of PPI(Private Participations in Infrastructures) projects. Also, success and failure of projects largely depend on the concession agreement contract. In this study, for more efficient negotiation, major issues are examined, and quantitatively analyzed to find out not only the relationship but also the characteristics of which these issues share. Questionnaire research was conducted through both research and by experts who were divided into an ordering agency, design company and constructor. Characteristics of major issues were quantitatively analyzed using the Likert index method, ANOVA(ANalysis of VAriance) and AHP(Analytic Hierarchy Process) analysis. Case studies were examined in order to estimate construction cost, rates of return, government finance support, level of operation-revenues guarantees, estimating operational costs and usage fees. With these 6 items, relative priority, relative impression which is sensible to risk and extent of difficulty in presenting data which is objective were quantitatively analyzed by the ordering agency, design company and constructor groups. From the analysis, there were some similarities between the design company and constructor groups while there was less of similarities between the ordering agency and design company or constructor. The government is diversifying the methods of project promotion, and PPI project from infrastructure-centered to public culture facilities are being expand. The current study will provide not only supporting efficient negotiation but also revitalizing PPI projects.
