A three-dimensional elastic blood vessel model with internal diameter variation is considered to investigate internal flow characteristics and effects of structural deformation. Also, computational analyses for both the rigid model and the fully-coupled FSI model have been conducted in order to compare the shear stress, pressure distribution, and flow velocity in detail. A 70% narrowing area of asymmetric blood vessel model was especially investigated to show the versatility of fluid-structure interaction phenomenon. The results reveal that effect of fluid-structure interaction is very important to accurately investigate the flow characteristics of the blood vessel.

The purpose of this study was to investigate the relationship between age, internal state information, and narrative structure. Another purpose was to examine how the kinds of replica play and story props affect the theme of children's narratives. The subjects were 36 4-and 5-year-olds. Children's narratives were audiotaped and analyzed accordmg to narrative structure, themes and internal state factors. The results indicated that 5-year-olds showed well organized narrative structure such as a descriptive narrative and a primary plotted narrative whereas 4-year-old presented no response and a descriptive narrative. Also, 5-year-olds used more internal state information in the narratives than 4-year-olds. The replica figures serve to remind the chiidren of story themes: the children with police props presented negative themes while children with playground props showed positive themes.

This research was to suggest the types according to structural system of the pagoda in ancient East-Asia and analyze the pagoda to the west of Mireuksaji temple site by these types. It will be possible to understand consistently the relation of the various form of the pagoda. The results of this research were described separately as follows. 1. The Buddhist pagodas founded in the ancient East Asia can be categorized according to their structural system, which provide us with insight to understand the interrelationship of categories. The pagoda is mainly classified into three categories. The first consists of two structures, an internal and an external structure. The second exposes its internal structure to the outside, and the third has the external components changing into the internal ones. 2. Although the pagoda to the west of Mireuksaji Temple Site have an internal and an external structures, it actually solves the structural problem by adopting the masonry structure in the outside as well as in the inside. Especially in this structural consideration can be found in the stylobate and the foundation structure of the pillar. The plan of the pagoda to the west of Mireuksaji Temple Site was intended to reveal the plane of the post-lintel layered construction which has a member, a main pillar, and the inner space in the cube with stones.

The purpose of this study is to examine the attributes and internal structure of fashion brand authenticity, which is a new concept of brand association. For quantitative research, a total of 591 samples of consumer survey were taken from 24th of August to 7th of September, 2009. The results of this study were as follows: 1) The scale for the fashion brand authenticity was developed, which consisted of 33 questions. These questions estimated a total of 8 dimensions, including heritage, authority, relationship to place, consistency, non-popularity, trend leading, originality, and ethics. 2) The internal structure of the fashion brand authenticity was confirmed. The internal structure was constituted into core attributes and promoted attributes. 3) The relationship between the fashion brand authenticity and consumer related variables were found. The core attributes of authenticity were putting positive influence directly on brand loyalty. However, paths through brand attachment or brand commitment were not found. The promoted attributes showed that it had a direct negative influence on brand loyalty, but it has also showed positive influence on paths, which underwent brand attachment and commitment.

The purpose of this study is to classify types of the eaves structure of buildings with the Jusimpo-type structure and to analyze the characteristics of each eaves structure. For this objective, forty buildings were selected and investigated. The results of analysis are summarized as follows. First, the main members of framework which handle a load burden on the long-rafter(長椽) are classified as the Jusim-dori(柱心道里) and the Oemok-dori(外目道里). Based on the method of handling a load, the eaves structure is classified into three types; the Jusim-processing-type(柱心中心形), the Oemok-processing-type(外目中 心形), and the Oemok-processing-variant-type(外目中心變異形). The Jusim-processing-type is the set where the internal length of a long-rafter is longer than the length of the eaves on the basis of the center of a column. The Oemok-processing-type is the set where the external length of a long-rafter is longer than the internal length of it. And the Oemok-processing-variant-type is the set where the internal length of a long-rafter is longer than the external length of it, but it is shorter than the length of the eaves which includes the extruded length of a Buyeon(浮椽). Second, the Jusim-processing-type had been generally adopted in the Jusimpo-type structure of the Goryeo Dynasty. But since the 17th century, the Oemok-processing-type had the highest application rate. Third, the change from the Jusimdori-processing-structure to the Oemokdori-processing-structure means that the long-rafter is moved to the direction of outside of the building, and thus the Jung-dori(中道里) is gradually moved to the column center. And, the change of the eaves with the Jusimpo-type structure was not a process for increasing the length of the eaves but a process for adopting the advantages of the Dapo-type structure by changing the arrangement of purlin. Fourth, the change from the Jusimpo-type structure to the Dapo-type structure could be understood as a process for moving the main point for handling a load from the Jusim-dori to the Oemok-dori.

A new non-destructive evaluation method using tapping sound is proposed. This method, named Tapping Sound Analysis, is using the difference between tapping sound data of healthy structure and defective structure as the criteria of determination of internal defect of composite structure. For the characterization of tapping sound, a feature extraction method based on wavelet packet transform is proposed. And a feature index is defined for the decision of existence of internal defects. To prove the possibility of proposed method as a non-destructive evaluation method, experimental study is performed. The tapping sound data of healthy structure and defective structure are measured and compared based on the proposed decision method. The experimental results showed that the feature index is a good indicator for the determination of internal defects.

The internal core baffle structure of a French Pressurized Water Reactor (PWR) consists of a collection of baffles and formers that are attached to the barrel. The connections are done thanks to a large number of bolts (about 1500). After inspection, some of the bolts have been found cracked. This has been attributed to the Irradiation Assisted Stress Corrosion Cracking (IASCC). The $Electricit\acute{e}$ De France (EDF) has set up a research program to gain better knowledge of the temperature distribution, which may affect the bolts and the whole structure. The temperature distribution in the structure was calculated thanks to the thermal code SYRTHES that used a finite element approach. The heat transfer between the by-pass flow inside the cavities of the core baffle and the structure was accounted for thanks to a strong thermal coupling between the thermal code SYRTHES and the CFD code named Code_Saturne. The results for the CP0 plant design show that both the high temperature and strong temperature gradients could potentially induce mechanical stresses. The CPY design, where each bolt is individually cooled, had led to a reduction of temperatures inside the structures. A new parallel version of SYRTHES, for calculations on very large meshes and based on MPI, has been developed. A demonstration test on the complete structure that has led to about 1.1 billion linear tetraedra has been calculated on 2048 processors of the EDF Blue Gene computer.
