The purpose of this study is to analyze the satisfaction, practical use, preference in design and recognition of the Saenghwalhanbok in the adult females living in Gyeongnam province. The data used for this study were collected by questionnaires and 420 questionnaires were used for statistic analysis. The data were analyzed by using the SPSS 8.0 to perform the ANOVA, $X^2$-test, t-test. The results of this study can be summarized as follows; Most women have Saenghwalhanbok for wearing in festive days. who showed good impression on the Saenghwalhanbok is high-educated people, and high-incommer showed positive preference as well. The color of blouse and skirt is different each other. The most preference color is soft color. The purchasing behavior on the Saenghwalhanbok was verified that there are planning of purchase because of convienience in wearing. The primary reason for not buying Saenghwalhanbok is price. So the goods of various level of price should be prepared, and the preference factors of purchasing for younger ages were color, patterns and design, and for old ages were quality of clothes, colors and patterns. Major application of the Saenghwalhanbok was found that wearing for festive days as it is Korean traditional costume.

The purpose of this study was to analyze the relationship between teachers' beliefs and instructional activities in regards to the DAP (Developmentally Appropriate Practice) of Korean and Chinese early childhood teachers. A number of both teacher variables and classroom environment variables were also examined. One hundred and ninety three Korean early childhood teachers and 385 Chinese early childhood teachers responded to the TeacherQuestionnaireas issued. The results of this study were as follows. First, Korean early childhood teachers showed higher scores in terms of teachers' beliefs about DAP than DIP (Developmentally Inappropriate Practice). Chinese early childhood teachers showed higher scores for teachers' beliefs about DIP. Second, Korean teachers' scores in terms of instructional activities for DAP showed differences depending on the degree of teaching experience and the teachers' age, and the scores for instructional activities related to DIP did not show any differences in any of the teacher variables. On the other hand, Chinese teachers exhibited different scores for the instructional activities for both DAP and DIP, again depending on the amount of teaching experience, the teachers' ages, and the ages of the children they taught. Third, a relationship between teachers' beliefs and instructional activities for DAP was found to be in evidence in Korea, but not in China.

Baroque period was fundamentally different from the previous ages in terms of various aspects. Not only the social, economical, and cultural changes, but also ways of experiencing architectural space were essentially changed. Space in Baroque architecture was no more confined in the strict medieval order and proportions, but it became more flexible and dynamic by applying many interesting spatial concepts as well as design methods. That is why Baroque architecture somehow has been re-considered in the present time. Various contemporary architects and theorists attempt to apply ideas in the Baroque architecture to enhance and rich spatial experience. This thesis aims to study the methods of constructing spatial depth in some of Baroque architecture. First of all, theoretical research on the Baroque art in terms of depth expressions compared to the previous ages based on Heinrich $W{\ddot{o}}lfflin$ was mentioned. After explaining the general concepts and methods of spatial depth in Baroque architecture, two case buildings were selected to be further analyzed. They are San Carlo alle Quattro Fontane and Cappella di Santissima Sindone. They have unique ways of expressing the spatial depth in which people experience particular spatial feelings. Based on the case analysis, this study was concluded that the ideas as well as design methods for spatial depth can be applied in contemporary architectural designs in various ways.

This research presents the effect of various ground pozzolanic materials in blended cement concrete on the strength and chloride penetration resistance. An experimental investigation dealing with concrete incorporating ground fly ash (GFA), ground bottom ash (GBA) and ground rice husk ash (GRHA). The concretes were mixed by replacing each pozzolan to Ordinary Portland cement at levels of 0%, 10%, 20% and 40% by weight of binder. Three different water to cement ratios (0.35, 0.48 and 0.62) were used and type F superplasticizer was added to keep the required slump. Compressive strength and chloride permeability were determined at the ages of 28, 60, and 90 days. Furthermore, using this experimental database, linear and nonlinear multiple regression techniques were developed to construct a mathematical model of chloride permeability in concretes. Experimental results indicated that the incorporation of GFA, GBA and GRHA as a partial cement replacement significantly improved compressive strength and chloride penetration resistance. The chloride penetration of blended concrete continuously decreases with an increase in pozzolan content up to 40% of cement replacement and yields the highest reduction in the chloride permeability. Compressive strength of concretes incorporating with these pozzolans was obviously higher than those of the control concretes at all ages. In addition, the nonlinear technique gives a higher degree of accuracy than the linear regression based on statistical parameters and provides fairly reasonable absolute fraction of variance ($R^2$) of 0.974 and 0.960 for the charge passed and chloride penetration depth, respectively.

This study was attempted in order to search for physical properties of sail cement. In this study, soil samples were specified according to soil particle analysis and used for compaction, strength, abrasion, absorption tests respectively according to different cement contents. Cement content sused in each treatment were 6%, 8%, 10% and 12% of total weight of soil-consent mixture. In the test, compressise strengths of the specimens were measured at the following ages; 3 days, 7-days, 14-days, 21-days and 28-days. Abrasion and absorption tests of the specimens were carried out at the 7-days age only. The results obtained from the tests are summarized as follows; 1. As the cement contents were in creased, the compressive strengths of soil-cement were almost proportionally increased. 2. The Compressive strength of soil-cement was not always proporportional to ages. The gradient of compressive strength of the soil-cement was steeper as the cement content was rucreased. 3. As the cement content was increased, the amount of the weight loss of the samples due to the abrasion was decreased remarkably, giving no abrasion for about 8% of the cement content. 4. As the cement content was increased, the absorption ratio of the specimens was not changed remarkably.

Based on the experiment results, the damage and fracture behavior of concrete at the ages of 1d, 2d, 7d and 28d, in three-point bending and uniaxial tensile tests, were simulated with a finite element program, ABAQUS. The critical stress intensity factor $K_{IC}^s$ and the critical crack tip opening displacement ($CTOD_C$) of concrete were calculated with effective-elastic crack approach for the three-point bending test of grade C30 concrete. Based on the crack band model, a bilinear strain-softening curve was derived to simulate the LOAD-CMOD curves and LOAD-Displacement curves. In numerical analysis of the uniaxial tension test of concrete of grade C40, the damage and fracture mechanics were combined. The smeared cracking model coupling with damaged variable was adopted to evaluate the onset and development of microcracking of uniaxial tensile specimen. The uniaxial tension test was simulated by invoking the damage plastic model which took both damage and plasticity as inner variables with user subroutines. All the numerical simulated results show good agreement with the experimental results.

The purpose of this study Is to identify factors for library space programs through user needs assessments in order to apply a library construction. Research method used was a questionnaire and subjects were residents and library users lived in Yongin where a new library was constructing. The results show that library use behavior, age, and user companions are identified as factors to influence to both functional space ratio and functional space arrangement. Heading in libraries is major activity and many subjects went to library with family so that family space is needed. Space for variable ages, also, is needed because of different needs based upon ages.

This Study is concerned with the color design of Korean and Japanese wooden architecture. The main subject of the study is to investigate the commonness and difference of color decoration between Korean and Japanese Buddhist 'Danchung' in the modern ages. In carrying this study into execution, I examined the architectural and historical backgrounds, and analysed the elements, techniques and principles of color design. The result of this study is as follows ; 1. 'Danchung' was originated from the practical functions in Chinese wooden architecture, and developed to embody sensuous beauty in Buddhist temple. The techniques and principles of color design and color tone of Korean and japanese Danchung had been similar in the ancient ages. But little by little they have differed in its function and color tone. So they are very different in modern times. 2. The dominant colors of Korean Danchung are red and green as 'Sang-nok Ha-dan(上綠下丹)', but Japanese's is only red as 'Bak-gan Juk-sun(白間赤線)' 3. Korean Danchung expresses and accentuates the important structural elements in three dimensions, on the other hand japanese Danchung takes two dimensional decoration on the unstructural elements 4. When seen in general, in Korean Danchung colors and their light and shade are simple and patternized. In the meantime, Japanese Danchung has many configurational expressions in general and is closed to paintings or picture.

The Hayabusa remote-sensing images of near-Earth asteroid (25143) Itokawa exhibited large diversity in spectral properties. The evidence suggests a various degrees of space weathering on the surface. It is known that the space weathering changes the spectra of S-type asteroids redder and reduces the depths of absorption around $1{\mu}m$. It is therefore possible to determine the surface ages through the investigation of the degree of space weathering. It is, however, reported that the scattered light components severely degrade the Asteroid Multiband Imaging Camera (AMICA) images, especially at the wavelengths > $0.86{\mu}m$. Our team came up with a technique for subtracting the scattered light components (Ishiguro 2014). Here, we upgraded the techniqu e by applying simplex algorism to correct the artifacts for all AMICA bands. This new technique enables to apply for the longest channel (i.e., zs-band at $1.01{\mu}m$) images, which was not studied so far. With the AMICA all bands data, we estimated the surface ages at the different location to be 0.6-2 Myr. Based on this data together with the geological information (e.g. gravitational potentials and local). we will discuss about the evolution of surface materials on the asteroid.

The pressure pain thresholds of head and neck muscles of patients suffering from tensiontype headache220, all female, ages ranged from 13 to 50 years (28.4$\pm$9.6) and 39 healthy controls, all female, ages ranged from 14 to 46 years (24.4$\pm$9.2) were recorded by the electronic algometer (Electyronic Algometer Type I, Somedic, Stockholm, Sweden). And the obtained results were as follows : 1. The pressure pain thresholds of patient group were lower than those of controls in superior sternocleidomastoid muscle, middle sternocleidomastoid muscle, and trapezius insertion muscle (P<0.001) 2. The pressure pain thresholds of patient group were not different from those of controls in anterior temporal, middle temporal, posterior temporal, deep masseter, anterior masseter, inferior masseter, medial pterygoid, posterior digastric, splenius capitus and upper trapezius muscle (P>0.05). 3. Seventy-one percent of tension-type headache patients had more than one muscle, of whicb pressure pain threshold was lowered significantly (less than mean of control - 1.5SD). 4. The pressure pain thresholds of head and neck muscles should be considered as a criterion for the diagnosis of tension-type headache.
