  • This thesis is to investigate the sliding behavior of cantilever retaining wall by using the commercially available program of FLAC to simulate its behavior numerically. Cantilever retaining walls with flat base, sloped base and base with shear key, uniform surcharges being applied on the surface of backfill, were investigated to figure out appropriate location of shear key beneath the base of wall and, thus, its applicability to field condition was assessed by comparing the analyzed results to each other. On the other hand, previously performed centrifuge model test results (Eum, 1996) were analyzed numerically with FLAC to compare test results with respect to characteristics of load-settlement of surcharges and load-lateral movement of wall. Based on the failure mechanism observed during centrifuge tests, limit equilibrium method of finding the ultimate load inducing the sliding failure of wall was used to compare with values of the ultimate load obtained from conventional method of limit equilibrium method. Therefore, appropriate location of shear key was determined to mobilize the maximum resistance against sliding failure of wall.

  • Purpose: The purpose of this study was to investigate the subjectivity of undergraduate students about happiness. Methods: Q methodology, which scientifically measures individual subjectivity, was used. Thirty-four Q-statements selected from 40 participants were classified into a shape of normal distribution using a nine-point scale. The collected data were analyzed using a PQMethod PC program. Results: Type I: Self-directed, growth-seeking type. This group of people searches for their objectives and direction in life while consistently making efforts to realize their goals. Type II: Oriental and wealth-seeking type. This group of people sympathizes with the oriental worldview and believes in having luck such as wealth or health. Type III: Realistic and pleasure-seeking type. This group of people tries to think positively but while rooted in reality, searches for pleasure and satisfaction in their surroundings. Type IV: Altruistic and relationship-seeking type. This group of people stresses the importance of religious life, small happiness in life, and relationship with friends or neighbors. Conclusion: The results of this study provide the foundation for understanding college students' perception about their happiness. Furthermore, these results suggest the necessity of specific and integrated education to improve happiness.

  • Dancing along with mankind has existed in various ways form old age to the present. This dancing combined with artistic meaning is called the art of dancing. This study is mainly about the functions decorations and expressions of dancing costume and the claracteristics of the costumes by the 20th century designers Leon bakst Oskar Schlemer Pablo Picasso. The dancing costume were not so much different from those of the public from old age to middle age. In 18th and 19th centuries the length of the cotstumes become short from the knee to the thigh. The functions have much to do with the development of dancing for example the appearance of toeshoes. The costumes are designed not to prevent the movements of dancers smooth line in old age and ladylike vend high-blown line in the 18th and 19th centuries. Cotton and hemp textiles are turning into the transparent forms such as lace and gauge. The personal ornaments earings and necklaces have change into the pattern with wings and tassels. The dancing costumes of Leon Bakst Oskar Schlemer and Pablo Picasso are designed after the due consideration of body shape. Bakst focused on the beauty of smooth lines with splendid colors and decorations. Schlemer analyzed the body abstractly and metaphysically and expressed it with detaile and simple lines. Picasso emphasized cubic forms with cubism and expressed the characteristics of costumes with clear colors and smooth curved line. Bakst Schlemer and Picasso made the early 20th century the age of functional dancing costumes putting a light on the concept of space and foundation for the modern dancing costumes.

  • The new paradigm of the 21st century demand an openly different world of formative ideologies in respect to art and design. The purpose of this study is focused on trying to comprehend aesthetic essence of clothing as an, with the investigation of artistic theories manifested by art philosophers. Art to Wear was categorized into style to understand its artistic meaning as well as to analyze its character. Upon the foundation of semiotics theory, the feature of Art to Wear and its analysis category were argued in the context of Charles Morris three dimension of semiotics analysis. The conclusion to the research is like so. The feature and analysis category of Art to Wear upon a semiotics perspective was divided into syntactic dimension, semantic dimension and pragmatic dimension. The analytical categorization upon the perspective of syntactic dimension fell into the category of topology, shape and color. The semantic dimension of Art to Wear was divided into categories of denotation and connotation. In addition, the pragmatic dimension of Art to Wear analytical categorization was divided into a delivering function and common function.

  • Nucleate pool boiling experiments were performed using pure R11 for various surface angles under constant heat flux conditions during saturated pool boiling. A 1-mm-diameter circular heater with an artificial cavity in the center that was fabricated using a MEMS technique and a high-speed controller were used to maintain the constant heat flux. Bubble growth images were taken at 5000 frames per second using a high-speed CCD camera. The bubble geometry was obtained from the captured bubble images. The effects of the surface angle on the bubble growth behavior were analyzed for the initial and thermal growth regions using dimensional scales. The parameters that affected the bubble growth behavior were the bubble radius, bubble growth rate, sliding velocity, bubble shape, and advancing and receding contact angles. These phenomena require further analysis for various surface angles and the obtained constant heat flux data provide a good foundation for such future work.

  • Air foil bearing supports the rotating journal using hydrodynamic force generated at thin air film. The bearing performance, stiffness, damping coefficient and load capacity, depends on the rotating speed and the performance of the elastic foundation, bump foil. The main focus of this study is to decide the dynamic performance of corrugated bump foil, structural stiffness and Coulomb damping caused by friction between bump foil and top foil/bump foil and housing. Structural stiffness is determined by the bump shape (bump height, pitch and bump thickness), dry-friction, and interacting force filed up to fixed end. So, the change of the characteristics was considered as the parameters change. The air foil bearing specification for analysis follows the general size; diameter 38.1 mm and length 38.1mm (L/D=1.0). The results show that the stiffness at the fixed end is more than the stiffness at the free end, Coulomb damping is more at the fixed end due to the small displacement, and two dynamic characteristics are dependent on each other.

  • In the present study, a new kind of multivariable Reissner-Mindlin plate elements with two kinds of variables based on B-spline wavelet on the interval (BSWI) is constructed to solve the static and vibration problems of a square Reissner-Mindlin plate, a skew Reissner-Mindlin plate, and a Reissner-Mindlin plate on an elastic foundation. Based on generalized variational principle, finite element formulations are derived from generalized potential energy functional. The two-dimensional tensor product BSWI is employed to form the shape functions and construct multivariable BSWI elements. The multivariable wavelet finite element method proposed here can improve the solving accuracy apparently because generalized stress and strain are interpolated separately. In addition, compared with commonly used Daubechies wavelet finite element method, BSWI has explicit expression and a very good approximation property which guarantee the satisfying results. The efficiency of the proposed multivariable Reissner-Mindlin plate elements are verified through some numerical examples in the end.
