현재 컴포넌트 기반 소프트웨어 엔지니어링의 접근은 소프트웨어 컴포넌트 인터페이스 디자인과 실행에 중심을 둔 경향이다. 컴포넌트 기반 소프트웨어 개발을 하기 위하여, 전체 시스템을 분석하는 것은 복잡하고, 이해하기 어렵다. 이를 위하여 aspect 기반 컴포넌트 개발방법을 도입한다. Aspect 기반 개발에서는 필요로 하는 컴포넌트를 표현하기 위하여 provide 와 require 를 사용한다. 또한 Aspect 기반 컴포넌트 엔지니어링을 위하여 컴포넌트 사이의 provide/require 서비스에 대한 분류와 추론을 위하여 다른 컴포넌트와 함께 이용할 수 있는 방법을 제안한다. 이 방법은 개발자들은 전체 시스템 개발을 위해 필요로 하는 적합한 컴포넌트의 provide/require 을 사용하여 접근하기 때문에 컴포넌트 검색, 합성, 재사용에 도움을 줄 수 있다. 컴포넌트 aspect 정보의 확장을 위하여 XML 문서 포맷을 사용함으로써 서로 다른 환경에서도 사용할 수 있도록 명세 하였다.

This study aims to find out the way of revitalizing of natural riverfront space in terms of ecological aspect. At the first part, theoretical made in terms of concept, planning aspects and techniques which were main bases for the study. It begins by explaining the concept of ecological riverfront space, the main aspect and techniques of its planning. After this, it analysis eight cases(four cases in Korea, Swiss, Germany, America and Japan) in terms of the objects, planning techniques and the results of development. It continues by making detailed analysis according to four objectives like 'protection from flood', 'quality of the river', 'ecological preservation' and 'active usage of riverfront space'. It ends by evaluating the relationship between objectives and the planning which will be adapted to the future development of riverfront space with ecological aspect. In conclusion, hereafter will propose desirable design-direction for revitalization about riverfront space about ecological aspect design in urban.

The composites of insulating polymer filled with conducting carbon-fiber were fabricated by molding press method. To understand the fiber aspect-ratio dependence of electrical conductivity the aspect ratio was varied from 4 to 10 The percolation thresholds of transition from the insulator to the conductor de-creased as the fiber aspect ratio increased. The percolation threshold of fiber-segregated composite in this study was smaller than that of fiber-random composite shown in other study. When the electrical con-ductivity curves were fitted by general effective medium equation morphological variable(t) decreased as the fiber aspect-ratio increased.

Experiments were performed by using PF-5060 and water to investigate the influence of an aspect ratio of a horizontal rectangular channel on the cooling characteristics from an in-line $6{\times}1$ array of discrete heat sources which were flush mounted on the top wall of the channel. The experimental parameters were aspect ratio of rectangular channel, heat flux of simulated VLSI chip, and channel Reynolds number. The chip surface temperatures decreased with the aspect ratio at the first and sixth rows, and decreased more rapidly at a high heat flux than at a low heat flux. The measured friction factors at each aspect ratio for both water and PF-5060 gave a good agreement with the values predicted by the modified Blasius equation within ${\pm}7%$. The Nusselt number increased as the aspect ratio decreased, but the increasing rate of Nusselt number reduced as the aspect ratio decreased. A 5:1 rectangular channel yields the most efficient cooling performance when the heat transfer and pressure drop in the test section were considered simultaneously.

The aspect ratio of a hole is defined as the ratio of the thickness to the diameter of the sheet metal. Most holes in the sheet metal industry are made by piercing. However, for thick sheets, which have an aspect ratio greater than 2, a machining process like drilling instead of piercing is usually used to make holes. In the current study, piercing, which is a shearing process, is evaluated to punch a hole with a high aspect ratio by using a newly designed die set-up. The piercing die was manufactured to prevent the punch from buckling and also to improve the alignment between the die components. An aluminum alloy sheet was selected for the experiments. The influence of several process parameters such as sheet thickness, clearance and stripping force were investigated. Experimentally, a hole with an aspect ratio of 5 was pierced. The resulting hole had a clean surface and the dimensional accuracy of pierced hole was considerably improved with decreasing clearance between punch and die. It is also shown that the larger penetration depth of the effective sheared surface can be achieved for high aspect ratio piercing relative to conventional piercing with a low aspect ratio.

Young's modulus of composite has been predicted by Eshelby's equivalent inclusion method modified with Mori-Tanaka's mean field theory, where short fibers of aspect ratio distribution are assumed to be aligned. Young's modulus of the composite is predicted with the smallest class interval for simulating the actual distribution of fiber aspect ratio, which is compared with that computed using different class intervals. Young's modulus of the composite predicted with mean aspect ratio or the largest class interval is overestimated by the maximum 10%. As the class interval of short fibers for predicting Young's modulus decreases, the predicted results show good agreements with those obtained using the actual distribution of fiber aspect ratio. It can be finally concluded from the study that if and only if the class interval of short fiber normalized by the maximum aspect ratio is smaller than 0.1, the predicted results are consistent with those obtained using the actual distribution of aspect ratio.

Besides dorsal-aspect target strength (TS) of the fish, side-aspect TS information is also acoustically important parameter in fisheries acoustics. In this study, the side-aspect TS of 11 black sea bream (Acanthopagurus schlegeli) were measured using a split beam echosounder of 120, 200, and 420 kHz; total length of the fish ranged from 12.4 to 23.7 cm, and wet weight from 27.5 to 229.8g. For the precise TS measurement with side-aspect angle, we used anesthetized and tethered specimens of known size while being rotated through $360^{\circ}C$ by means of a carousel structure. The side-aspect TS measurements of the fish were conducted by rotating the fish in the horizontal plane at 50 interval. The ping interval was 0.2 second and elapsed time at each angle was 30-60 second. As a result, the measured side-aspect TS data were fitted by sinusoidal function. The relationships between fish length and near full side-aspect TS were as follows: $TS_{120kHz}= 21.46 log (TL)-67.5 (r = 0.70), \;TS_{200 kHz}= 31.03 log (TL)-76.9 (r=0.83),\;TS_{420 kHz}= 30.79 log (TL)-72.2 (r = 0.77)$. For comparison, theoretically estimated side-aspect TS from the Kirchhoff ray mode (KRM) model, which based on swimbladder and body morphology, were compared with the measured TS.

The purpose of this study was to analyze the within-group verbal interaction according to leader's personality in Thinking Science activities. For this study, 2 homogeneous small groups by cognitive level selected from one class of sixth grader. Each group was comprised of four students. Leaders of two groups selected from the results of NEO personality assessment and teacher's observation. One who got high scores in extraversion and agreeableness is named a sociable leader, the other who got low scores in extraversion and agreeableness is named a taciturn leader. Verbal interactions during small group activities were audio/video taped and students' interactions were classified into on-task and off-task. On-task included cognitive aspect and affective aspect. Interactions of cognitive aspect were divided into low and high level, also interactions of affective aspect were divided into positive and negative interaction. The results of this study showed that the verbal interactions in the sociable leader group were more activated than those in the taciturn leader group. Also, interaction level of the sociable leader group in cognitive aspect was higher than those of the taciturn leader group. In affective aspect, interaction pattern of the sociable leader group was similar to those of the taciturn leader group. The characteristics of leader's interaction are as follow. The rates of cognitive aspect in the sociable and the taciturn leaders' interactions were much higher than those of affective aspect. This tendency was especially remarkable in the taciturn leader's interactions. However, interaction level of the sociable leader in cognitive aspect was higher than those of the taciturn leader. In affective aspect, positive interaction rate of the sociable leader and the taciturn leader were higher than negative interaction rate.
