This study attempted to undertake comparative analysis of woman's jacket pattern and details based on the Crinoline and Bustle style of the 19th century, comprehend the relation and differences between the two styles. And it also presented the resultant characteristics and attempted reproducing the original dress of the past for the development of modern woman's jacket design. Larger portion was occupied for the breast front width than the back width for both Crinoline and Bustle style, which indicated the remarkable difference between these styles and modern jackets in terms of pattern size. Circumferences also showed that both styles had larger size for the front region than for the back. Divided by two types of pattern shape. The Crinoline style has a waist line and flare. On the other hand, the Bustle style does not have a waist line and has pleats. These two styles shows distinct differences of patterns even if they seem similar. It was essential to undertake the designing of models by giving a consideration to the characteristics of patterns of the two styles. With respect to how to sketch the study models which will be applied for the reproduction to modern body sizes were as follows: the front bust circumference; B/4 +1+1 cm, the back bust circumference; B/4 +1-1 cm, front waist circumference; W/4 +1+1 cm, back waist circumference; W/4 +1-1 cm, the height of sleeve crown; AH/3, armhole line; B/4, the back width /2; 17.5 cm, the breast front width /2; 16.5cm. And for the rest parts, sizes reflecting the characteristics of the patterns of two styles have been applied.

With a view to developing male dress forms for educational purposes, human body measurement was made for male adults in their twenties residing in Busan, Korea. Based on the results, the following conclusion was obtained: 1. Comparison d the measurement in Busan and the data of the 5th Korean physical dimensions(Size Korea) In the comparison of the Busan male adults in their 20s with national physical dimensions(Size Korea) by way of the Mollison relational deviation line, all the 28 items revealed differences less than 0.7. As the Busan sample reflects the body type d the average Korean men in their 20s, Busan's measurement results can be safely used as the data for dress form development. 2. Results of front body type classification According to the factor analysis, seven factors of the front body type were produced to explain 77.25%. The factors were shoulder angles, waist height, hip shapes, chest shapes, proportion of body(chest, waist, hip)width to shoulder width and so on. Cluster analysis brought about three somatotype groups. First, the body type with the least differences in hip-waist width, shoulder-waist with, and hip angles (24,23% in appearance) was named Type H. Second, the body type with the most chest-waist width and hip angles (38.66% in appearance) was called Type Sam X Third, the body type with the greatest shoulder-chest width, shoulder-hip width, and shoulder angles (37.11% in appearance) was termed Type Y.

Purpose : The purpose of this study was to compare the fracture resistance of the IPS Empress ceramic crown with 1.0mm width rounded shoulder, which is usually recommended in all ceramic crown. and 0.5mm width chamfer finish lines on the maxillary central incisor. Material and method : After 15 metal dies were made for each group, the IPS Empress all ceramic crowns were fabricated and cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. LTD., Japan) on the metal die. The cemented crowns were mounted on the positioning jig and the universal testing machine(Zwick Z020, Zwick Co. Germany)was used to measure the fracture strength with loading on the incisal edge. And also, three-dimensional finite element stress analysis was used to measure the stress distribution with the various types of the finish lines(1.0mm width rounded shoulder, 0.5mm width chamfer), the loading site(incisal edge, incisal $\frac{1}{3}$) and the type of loading(concentration loading, distribution loading). Results and conclusion : 1. In the fracture resistance experiment according to the finish line, the mean fracture strength of rounded shoulder(876N) and the mean fracture strength of chamfer(882N) did not skew any significant difference between each other(p>0.05). 2. The stress distribution of all ceramic crown in three dimensional finite element analysis showed concentration aspect at loading point and cervical area or labial surface. 3. In metal die, there were no differences in stress distribution between finish lines, but in natural teeth model, chamfer finish line showed higher stress than rounded shoulder finish line. 4. When force was loaded on the incisal edge the stress was concentrated on the incisal edge and the cervical area of labial surface. When force was loaded on the incisal $\frac{1}{3}$, the stress concentrated on the cervical area of labial surface and the cingulum area. 5. Generally, natural teeth model showed higher and various stress than the metal die.

Small RFID tag antenna were fabricated on Si substrate and their physical and electrical properties were evaluated. With decreasing the size of tag antenna on Si substrate, small SMD-type RFID tags could be fabricated, which is very useful for various applications including PCB tracking. Firstly, electromagnetic properties on tag antenna pattern were simulated with HFSS. The setup frequency was 13.56 MHz of HF-band RFID. The line-width and line-gap were modeled in the range of $50{\sim}200{\mu}m$. S parameters, SRF, and Q value were calculated from the model. When the line-width and line-gap were 100 urn and the loop-turn was 10, the SRF was 80 MHz and the Q value was ca. 9. When the microstrip antenna pattern of aluminum was fabricated by using DC sputtering, Vpp of ca. 1.6 V was obtained when the reader-tag distance was 40 mm.

In this paper, transmission lines with low and high characteristic impedance (Z$_{0}$) are fabricated and analyzed. The transmission lines are fabricated on the benzo-cyclo-butene (BCB) films of a low dielectric constant. For the low Z$_{0}$, two types of coplanar waveguide (CPW) structures are fabricated, which include bottom-ground and double-ground type. Measurement shows that Z$_{0}$ values for each CPW type are 7.3 and 9.4$\Omega$, respectively, at a signal line width of 100 #m. Whit the ratio between the spacing of bottom-ground and the signal line with becomes greater than 2.5, the Z$_{0}$ is nearly saturated. In addition, thin film microstrip lines fabricated using the BCB insertion layers show very low Z$_{0}$ of 25.5$\Omega$, and this impedance is ~64 % of the values obtained from the BCB-based CPW structures of the same line width. Measurement result of CPW on BCB layer is 100.5 Ω.s 100.5 Ω.

In this paper, the dependence of interconnect line-induced delay time on the size of CMOSFET gate width is characterized. In case of capacitance dominant interconnect line, the total delay time decreases as transistor size increases. However, there exists a transistor size for minimum total delay time when both of resistance and capacitance of interconnect line become larger than those of transistor. The optimum transistor size for minimum total delay time is obtained using an analytic equation and the experimental results showed good agreement with the calculation.

The purpose of this research was to investigate the differences in the ski carving turn motion according to level of expertise. The posture and movement of 6 skiers nearby the fall-line was evaluated with a biomechanical approach focusing the rotational mechanics. The slope was at an angle of $9^{\circ}$ and the following variables were measured and calculated: tangential velocity, change of COM height after passing fall-line, width between feet, angle between upper body and thigh, trunk angle, average radius of curvature and average centripetal force. The expert skiers minimized their center of mass height movement and maintained the width of between their feet after the passing the fall-line in comparison with the beginners and intermediate skiers. The experts restrained themselves from pushing their upper body downward after the turn to maximize the centripetal force. The experts in comparison with the beginners and intermediate skiers during the turn didn't have to reduce their radius of curvature to maintain a high centripetal force. It was concluded, that the most important factor affecting the centripetal force, was for the beginners and intermediate skiers, to minimize their movement while using the appropriate amount of edging.

Points of sharp variations in image are the most important components when we analyze the features of image. And they include a variety of information about image's shape and location etc. So a lot of researches for detecting edges have been continued. Edge detection operators which were used at the early stage of the research were to utilize relations among neighboring pixels. These methods detect edge at all boundaries, therefore they perform edge detection twice about curves below some width such as line-edge. In the meantime, wavelet transform which is presented as a new technique of signal processing field provides multiscale edge detection and is being applied widely in many fields that analyze edge-like characteristic. Therefore, in this paper we detected line-edge with new 2-D wavelet function which is independent of line's width.
