Steady state flow calculations are executed for turbo-pump inducers of modern design to validate the performance of Tascflow code. Hydrodynamic performance of inducers is evaluated and structure of the passage flow and leading edge recirculation are also investigated. Calculated results show good coincidence with experimental data of static pressure performance and velocity profiles over the leading edge. Upstream recirculation, tip leakage and vortex flow at the blade tip and near leading edge are main sources of pressure loss. Amount of pressure loss from the upstream to the leading edge corresponds to that of whole pressure loss through the blade passage. The viscous loss is considerably large due to the strong secondary flow. There appears more stronger leading edge recirculation for the backswept inducer, and this increases the pressure loss. However, blade loading near the leading edge is considerably reduced and cavitation inception delayed.

This research surveys the forming process of Practical Korean Costume and its social factors and examines Hanbok reformation. The international mode of '86 Seoul Asian Games and '88 Seoul Olympic Games in the 1980's called for the modernization of Hanbok. It is necessary for us to inherit modernized Hanbok which is endowed with the traditional beauty. The purpose of this research is to develop Practical Korean Costume design for focused on functionality as well as on keeping the traditional beauty This study consist of theoretical study and positive study. Theoretical study has the esthetic characteristics(structure characteristic, formative characteristic and the characteristic of color). Grounded upon survey on brands, I have suggested designs that maintain Hanbok's superiority and functionality to fit modern life. Most of Practical Korean Costume shops could not fractionalize customer. So it need to subdivide and specialize customer and investment to improvement of design. Practical Korean Costume will have to be made to maintain dignity by using high quality materials and a coordinate goods will have to be developed.

The tidal deposits in the Haenam Bay, southwest coast of Korea, are stratigraphically divided at least into two units (Unit I of Holocene and Unit II of late Pleistocene) based on the obtained vibracoring sediments. In Unit I, clay minerals of illite, chlorite, kaolinite and smectite are observed as similar to those of the other modern tidal deposits. Of note, however, is the absence of smectite and chlorite in the upper part of Unit II compared with the clay mineral compositions of Unit I. It is concluded that the subaerial weathering and diagenetic effects rather than depositional processes are responsible for the positive and characteristic differences in clay mineral compositions between two units, that is, the upper part of Unit II was exposed subaerially and weathered diagenetically prior to the late Holocene transgression. Therefore, the bounding relationship between Unit I and Unit II is unconformable.

The purpose of this thesis is to make clear particulartity of young adult generation which leads industry in their demands so that fashion trends are foresaw, and to describe style of costume satisfied with picture of new male. This thesis is to consider young adult style of costume in terms of double root described by W$\ddot{o}$lfflin in the internal meaning and the external form, so as to analyze their unique style. In conclusion, domestic young adult style of costume is embodied in the internal meanings of individuality, aestheticism and new classicism in terms of the external forms which means body-priority-form by open-form, whole-form, integration-form, rounded-form, indeterminate-form. With these results, domestic fashion industry is demanded to be from classic to modern expressions so as to be reflected in sophisticated masculinity of young adult.

Due to the large size and high complexity of modern buildings, the interest and the studies about indoor spatial information are increasing. Previous studies related to indoor spatial information were mostly about relevant technologies, and the application of indoor spatial information has been less studied. In the present study, the public administrative work areas where indoor spatial information may be applied were identified by using a modified delphi technique. And the indoor LOD (Level of Detail) and indoor positioning accuracy for indoor spatial information applications considering user requirements was established as standards for efficiently establishing and providing services. The required LOD and positioning accuracy for services was established by reestablishing indoor LOD and positioning accuracy and classifying services with reference to those. The indoor LOD was reestablished from LOD 0 to 4 by focusing on service utilization and general recognition, and the positioning accuracy was reestablished in three levels by considering the accuracy of the present positioning technology and service utilization status.

Programming ability becomes an essential ability for elementary and secondary school students as well as computer science major students in modern information society. Thus, improving programming ability has long been a research project for computer scientists and teachers in IT areas. There have been many research works for improving programming ability in various ways. At first glance, emotional intelligence is generally known as humanistic intelligence, and nothing to do with computer areas. In the recent works, emotional intelligence has a correlation with various subjects. The purpose of this paper is to analyze correlation between emotional intelligence and programing ability. For this purpose, extensive survey works are carried out and statistical results are analyzed. Based on statistical analysis, it is concluded that there is a correlation between emotional intelligence and programming ability.

This study is to investigate the cognition and usage of traditional wedding food in Seoul & Gyeonggi area. It provides the basic suggestions for developing the best wedding culture, upholding the great wedding tradition. People usually prepared traditional wedding food only because they had to do since they thought it was a formal way to do it at a wedding ceremony. However, there should be more important things to be considered. Firstly, to understand the real meaning of traditional wedding food, we need to inform its meaning by starting campaigns on wedding culture or making booklets of traditional wedding food. Secondly, to prepare the right selections of traditional food, we need to simplify traditional wedding food and consider the modern sense of the products. Thirdly, to improve traditional wedding food, we need to develop diverse menu. By doing it, we can efficiently reduce the cost of wedding food.

The use of drug or substance for altering consciousness among adolescence is a practice in modern society, especially in Korea. The choice and pattern of use are strongly influenced by the user6s personality and expectations. The goverment and society institute must be declared the emergency of Drug abuse, for the purpose of protecting adolescence from pscychotropic agents.

Resolving of memory access latency is one of the most important problems in modern embedded system design. Recently, tons of studies are presented to reduce and hide the access latency. Burst/page data transfer modes are representative hardware techniques for achieving such purpose. The burst data transfer capability offers an average access time reduction of more than 65 percent for an eight-word sequential transfer. However, solution of utilizing such burst data transfer to improve memory performance has not been accomplished at commercial level. Therefore, this paper presents a new technique that provides the maximum utilization of burst transfer for memory accesses with local variables in code by reorganizing variables placement.
