The purpose of this study was to investigate the images and characteristic formative elements of Korean traditional patterns. The Korean pattern image could be interpreted into visual elements of design based on the images, the characteristic formative elements of Korean traditional patterns, and their relationships. Fourteen patterns selected from 5 groups of Korean patterns were used as stimuli. An image evaluation using a 2-point sementica scale of 19 bipolar adjectives, and an impression evaluation of which results were presented by visual drawing using lines and shapes were carried out. The data were analyzed by correspondence analysis and cluster analysis. The major findings are as follows; 1. Fourteen patterns and 19 adjectives were marked on a perception map composed of two (x and y-) axes. The bipoles of x- and y axes were soft-hard and splendid-artless, respectively. 2. Four clusters semerged to account for the dimensional sturucture of 14 patterns and 19 adjectives. These were splendid image, soft image, individualistic image, and sophisticated image. However there was no pattern which belonged to the cluster, sophisticated image. The Korean pattern image was founded to be better related to the kind of patterns than the type of patterns. 3. The characteristic formative elements obtained from the impression test were contour of motif, repeated line or shape, various curved lines, and decorative elements. 4. The splendid image was related to Bongwhang patterns and detailed line and complexity. The individualistic image was related to the abstractive form of Bongwhang pattern and the decorative form of Cloud pattern both of which have the characteristics of point-symmetry and abstraction, and Turtle-back pattern. In this case, the related charac-teristic formative element was identified to be repeated lines. The soft image was related to Moran, Cloud, and Taegeuk patterns. The related characteristic elements were various types of curved lines, decorative elements, and rounded contours.

This study examined how the three major newspapers covered the press reform movement in Korea. Despite that the NGOs and Korean government keep trying to reform the market and structure of the newspapers, the targeted newspapers argue that they are unjustly accused of the dominance of the press market made by the readers' choice. Using frame analysis and discourse analysis, this study analyzed the news coverage on the press reform for 6 months and revealed that these major newspapers presumed to be targeted were totally challenging against the press reform by means of flaming of news and using news discourse. The ways of challenge were, firstly they appealed to the readers that the press reform is the press suppress so that they have to fight against this unacceptable pressure. And secondly, they report the news selectively for their own interests by elaborating, magnifying, or reducing the facts. Thirdly, they attack the government policies and major figures leading the press reform by letting the outside columnists favorable to their own standing point. And finally, they conduct the poll on and off and report what they want according to their self interests.

In recent years, the subject of remaining life assessment has drawn considerable attention in power plants, where various structural components typically operate at high temperature and pressure. Thus a life prediction methodology accounting for high temperature creep fracture is increasingly needed for the components. Critical defects in such structures are generally found in the form of semi-elliptical surface crack, and the analysis of which is consequently an important problem in engineering fracture mechanics. On this background, we first develop an auto mesh generation program for detailed 3-D finite element analyses of axial and circumferential semi-elliptical surface cracks in a piping system. A high temperature creep fracture parameter $C^{\ast}$-integral is obtained from the finite element analyses of generated 3-D models. Post crack growth module is further appended here to calculate the amount of crack growth. Finally the remaining lives of surface cracked pipes for various analytical parameters are assessed using the developed life assessment program.

This study is to consider the geographical images of Nakdong River region represented in the Modern Poetry. The findings are as follows. First, the change aspect of the poetry around Nakdong River area shows the social phenomenon of population movement, economic deprivation symptoms, the Korean War, economic development plans, the industrialization and spatial inequalities, environmental problems and environmental poetry, and various environmental issues, etc. Second, the poetry about Nakdong River can be classified by geographical area, showing a humanistic geographical image of the sense of place, natural geographical images about geomorphology and climate, and regional development and environmental pollution. Finally, the large number of poetry describes the beautiful terrain and the sense of place of poet, among ones targeting the upsteam of Nakdong River. The one in middle and downstream areas, however, reflected the reality and was social criticism mostly. This is because that, compares to the upstream, many large cities are distributed in the downstream area and the river becomes increasingly contaminated as it flows to the downstream.

The purpose of this study was to concentrate on macroscopic discussion about how the recurrence of actual case in move is accepted ideologically. When considering the characteristic that non-visual factors are embodied when movie image reflects a certain target, the issue of recurrence has always caused discussion. Regardless of its independence or dependence, one individual's experience can be similar to sensual recognition but it can't be identical. Therefore, 'the truth recurred by movie' can't be real 'truth'. When director expresses the target, the aesthetic intention gives an effect to audience's emotion and recognition, Therefore, the study tries to review whether the movie truth drawn by movie can reach the possibility of epistemology agreement.

Recently, KTX (Korean Train Express) train stoppage accidents were mainly caused by malfunctioning equipment, aging and cracking of railway vehicles, crack breakages of brake disks, and breakages of brake disks. Breakage of brake disk can cause large-scale casualties such as high-speed collision and concern about derailment by hitting lower axle and wheel. Therefore, in this study, a brake disk with solid and ventilation type, which is the brake disk of a KTX train was modeled, and a dynamometer system was constructed to operate the disk. A Rayleigh wave was used to inspect the surface of the brake disk. An ultrasonic inspection module was developed for the brake disk by using a local immersion method due to the difficulty involved in ultrasonic inspection using an existing immersion method. In addition, the surface defects of the brake disk were evaluated using a dynamometer mock-up system and an ultrasonic inspection module of the brake disk.

유도결합 플라즈마를 이용한 식각 장치에서 플라즈마 균일도 향상에 대한 수많은 연구가 이뤄지고 있다. 안테나의 디자인, 인가 전력과 주파수, 안테나와 기판간의 거리, 기판과 챔버 외벽간의 거리 등 다양한 변수들이 변화되어 왔다. 또한, 최근에는 식각 균일도뿐만 아니라 식각 속도 향상에도 많은 관심이 모아지면서 유동에 영향을 주는 GDP 구조가 다시 중요해지고 있다. 본 연구에서는 300 mm 식각장치를 형상화하고, GDP의 구조와 유량비에 따라 플라즈마의 균일도에 어떻게 영향을 끼지는지 사용 유체역학 전산모사 프로그램인 CFD-ACE+를 이용하여 예측해 보았다. 안테나는 2중 직렬방식으로 안쪽과 바깥쪽의 안테나에 각기 다른 전력을 인가 할 수 있는 구조를 사용했으며, 압력은 10에서 60 mTorr까지 변화시켰다. GDP의 구조는 안쪽 입구와 바깥쪽 입구가 있으며 역시 따로 유량을 조절할 수 있도록 설계하였다. 안쪽 입구는 수직방향을 향하고 있으며, 바깥쪽 입구는 90도 이내의 각을 갖도록 꺾여 있는 것과 수평방향으로 주입할 수 있는 구조, 두 가지를 사용하였다. 유량 비율은 안쪽 입구와 바깥쪽 입구를 2:8, 5:5, 8:2로 고정하였다. 우선 GDP의 구조가 90이내의 각을 갖도록 주입되는 구조에서는 어떤 유량비율에서도 약간의 vortex가 발생했다. 수직방향의 유량이 감소될수록 기판에서 멀리서 발생했으며 강도 또한 감소했다. 기판 표면에서의 압력분포 균일도도 8:2에서 2.8%, 2:8에서 0.6%로 향상되었다. 2:8의 유량 비율에서 압력을 10에서 60 mTorr까지 향상시키면 vortex 효과는 감소되나 기판에서의 압력 균일도가 0.8%까지 약간 나빠졌다. 여기서 발생되는 vortex는 GDP 구조를 수평방향으로 주입되기 함으로서 해결할 수 있었으며, 압력 균일도도 0.2%까지 향상시킬 수 있었다. 또한, 강한 수직방향의 유량은 중심에 발생하는 플라즈마의 중앙을 밀어내는 효과를 확인했으며, 실험적 증명이 추후 연구단계로 진행될 예정이다. 식각 균일도나 식각 속도를 예측하려면 CF계열의 복잡한 가스를 사용해야하기 때문에 유량이 플라즈마에 미치는 영향을 보기 위해서 본 연구에서는 단일종인 Ar 가스만을 사용하였다. 첫 단계로 이와 같이 최적화시킨 유동조건에서 복잡한 식각가스를 이용한 플라즈마 계산은 다음 단계로 준비 중에 있다.

This thesis is a study for the standardization of the design of ginseng cultivating facility (also known as the sun off facility) for the improvement of farming environment. The core background of this study is to propose a basic study for introducing, for the first time, the modern ginseng cultivating facility that matches the position of korea as a main nation cultivating ginseng and to secure the production and quality value of Koryo Ginseng, which is a special world-level agricultural product of Korea, under the present WTO agricultural product open system. Right now, wood, rice straw, or vinyls, which are non-standardized or are for one-time use only are used. Therefore, as a concept of the design, 1 tried to revise the fact that these materials are being used to set up the facility repeatedly every year which is creating environmental pollution and wasting of our countries labor and resource. Concrete factors to be improved are as follows: First, standardization of the form and structure of mass production system; Second, introduction of new materials such as semi-permanent resin etc., for standardization of materials; 1 tried to make the above two factors into a shape based on a Korean image. As for the design, designed a standard unit model of the ginseng cultivation facility especially keeping in mind to design it so the facility can be freely connected and assembled according to the size and shape of the cultivation area.
