The purpose of this study is to propose evaluation factors for elementary school facility in terms of educational adequacy. The focal point of this study is to clarify the proper measure of educational facility evaluation in the light of specific characteristics of facility. In order to improve the level of educational adequacy, more information is needed regarding school facility design and various factors which affect to the design. This is important works because such information is essential in implementing facility design to meet the needs of the new educational policy. To get the goal, first, it is attempted to analyse the meaning of design information which deeply affect on the school facility design. The design information is classified into three main aspects, such as human aspect, social aspect and physical aspect. The design information regarding the physical space verses human psychology and behavior belongs to category of human aspect. Pedagogic ideology which varies depend upon the time and regions is classified into the category of social aspect. The Physical aspect means efficient equipment performance of space to support educational activities effectively. Secondly, as for the educational adequacy evaluation concern, it is attempted to select more items which usually has been neglected by the existing evaluation criteria which mainly emphasized functional performances only. With the premise of the above, in this paper, it is attempted to propose proper evaluation factors in terms of educational adequacy for school facilities. As the research methods, researching of literature on this subject, field trip, interview, site analysis, and survey is used.

The aim of this research is to analyse the dynamic characteristics of the hot upper smoke layer in case of fire in a tunnel. In order to get the result, computer simulation technique has been used. The fire scenarios were set on the basis of standard cross section of national and express highways through NIST's FDS. As the area of a tunnel increased, the influence of the wind velocity decreased. Furthermore, the influence of the slope of a road was reduced as the wind velocity increased. On the other hand, as the wind velocity increased, the influence of the slope of a road decreased. This phenomena is believed to be caused by the cooling effect of wind which is over 1 m/s in speed, hence, reducing the influence of the effect of slope.

On marine vessels, delicate instruments such as navigation radars are normally mounted on ship masts. However the vibrations at the top of mast where the radar is mounted often cause serious deterioration in radar-tracking resolution. The most serious problem is caused by the rotational vibrations at the top of mast that may be due to wind loading, inertial loading from ship rolling and base excitations induced by the running propeller. This paper presents a method of semi-active vibration control using magneto-rheological (MR) dampers to reduce the rotational vibration of the mast. In the study, the classical optimal control algorithm, the independent modal space control algorithm and the double input - single output fuzzy control algorithm are employed for the vibration control. As the phenomenological model of an MR damper is highly nonlinear, which is difficult to analyse, a back- propagation neural network is trained to emulate the inverse dynamic characteristics of the MR damper in the analysis. The trained neural network gives the required voltage for each MR damper based on the displacement, velocity and control force of the MR damper quickly. Numerical simulations show that the proposed control methods can effectively suppress the rotational vibrations at the top of mast.

Bioimaging that can be imaging phenomena within cells of a molecular size have been advanced in technology. We can observe clearly DNA and proteins using a confocal microscope. Currently biological fluorescent imaging area is used essentially for diagnosis and treatment in health and clinical care field. In this paper, we developed an integration management system of analyzing fluorescence images on smart phone. It can support a user to analyse fluorescence images anytime anywhere. And our system is based on client-server configuration and has functions that can figure intensity of fluorescence images and manage many imaging data. Proposed system can be a mean of ubiquitous health because it helps a doctor diagnose by analyzing fluorescence images of emergency patients without time and space restrictions.

We can see various cultural elements appeared in modern fashion, of which Korean traditional cultural elements are being reinterpreted in many different ways. This study is to analyse on the basis of togetherness concept Korean traditional elements, which have been considered difficult to interpret by postmodernism and find the ways how to carry on our traditional culture practically in order to prepare the foundation for globalization of our tradition. Togetherness means 'with' or 'simultaneously', which also conveys the meaning of common cause and result, addition and annex, opposition and juxtaposition, or accumulation and integration. Characteristics of the togetherness appeared in Korean fashion are as follows. First of all, it shows the aspect of mixing and integration of different cultural fashion elements around the globe, which have been made possible in the course of globalization and development of information technology. The second characteristic is crossing and synchronization, which means that many different individual fashion elements in terms of time and space are being crossed over and integrated these days. Thirdly, continuation meaning 'without cease' and 'keep going' shows that togetherness is to create a whole new fashion trend by mixing postmodern revivalism and past clothing elements. Togetherness makes it possible for us to find reasons why tradition aspects are expressed so vividly in the modern clothing, gives us a standard to classify the reasons, establishes an identity and offers theoretical background for globalization of traditional clothing in the course of modernization of our tradition.

The study investigated an area of sustainable structural design that is often overlooked in practical engineering applications. Specifically, a novel method to simultaneously optimise the cost and embodied carbon performance of steel building structures was explored in this paper. To achieve this, a parametric design model was developed to analyse code compliant structural configurations based on project specific constraints and rigorous testing of various steel beam sections, floor construction typologies (precast or composite) and column layouts that could not be performed manually by engineering practitioners. Detailed objective functions were embedded in the model to compute the cost and life cycle carbon emissions of the different material types used in the structure. Results from a comparative numerical analysis of a real case study illustrated that the proposed optimisation approach could guide structural engineers towards areas of the solution space with realistic design configurations, enabling them to effectively evaluate trade-offs between cost and carbon performance. This significant contribution implied that the optimisation model could reduce the time required for the design and analysis of multiple structural configurations especially during the early stages of a project. Overall, the paper suggested that the deployment of automated design procedures can enhance the quality as well as the efficiency of the optimisation analysis.

This thesis aims to consider theories of job information on foodstylist, conduct a survey among culinary arts science high school students who are in the most critical period of decision-making for the future career, and analyse the survey results on foodstylist by using SPSS10.0. The analysis shows that culinary high school students mainly get their job information on foodstylist through mass media. Thus, it can be deduced that use of mass media and the Internet can be the most effective to promote the awareness level of foodstylist. Culinary high schoolers' parents were positive about female students' being foodstylists, and those going to college showed more interest than job seekers about being foodstylists. In addition, the result of Bonferroni post-hoc test according to parents' monthly income showed that those with higher monthly income were positive about their children's being foodstylists. However, given that culinary high schoolers' overall satisfaction is low, provision of the information through a variety of information channels is necessary. It is expected that promotion of the information provision will serve a turning point in awareness.

High resolution spectroscopy of the yellow symbiotic star AG Draconis is performed with the Canada-France-Hawaii Telescope to analyse the line profiles of Raman scattered O VI broad emission features at $6825{\AA}$ and $7082{\AA}$ with a view to investigating the wind accretion process from the mass losing giant to the white dwarf. These two spectral features are formed through inelastic scattering of O $VI{\lambda}{\lambda}32$ and 1038 with atomic hydrogen. We find that these features exhibit double-component profiles with red parts stronger than blue ones with the velocity separation of ~ 60 km s-1 in the O VI velocity space. Monte Carlo simulations for O VI line radiative transfer are performed by assuming that the O VI emission region constitutes a part of the accretion flow around the white dwarf and that Raman O VI features are formed in the neutral part of the slow stellar wind from the giant companion. The overall Raman O VI profiles are reasonably fit with an azimuthally asymmetric accretion flow and the mass loss rate ~ 4 ${\times}$ 10^{-7} M_sun yr^{-1}. We also find that additional bipolar neutral regions moving away with a speed ~ 70 km s^{-1} in the directions perpendicular to the orbital plane provide considerably improved fit to the red wing parts of Raman features.

The purpose of this study was to analyse the runoff characteristics of non-point pollution sources in an urban watershed and determine the effectiveness of newly installed riverwater treatment system to reduce water pollution caused by storm runoff in the urban watershed. The results of this study showed that the levels of BOD5 and suspended solid were highly influenced by first-flush effect and the pollutant load of those two parameters were also very high in the urban watershed. Meanwhile, the effectiveness of riverwater treatment system to reduce the levels of BOD5 and suspended solid was relatively high, but those to reduce the levels of T-N and T-P was low, which needs some additional unit treatment process such as filtration and coagulation. Nonetheless, the riverwater treatment system tested was relatively simple in installation and operation, effective in removing many water pollutants and, most importantly, does not require much space as other treatment systems, so it could be an attractive alternative option to reduce riverwater pollution caused by storm runoff in urban watersheds.
