  • The purpose of this study was to figure out visual character and preference of roadscape for the main entrance road in Chongju. We took 9.6km which was from the Chongju interchange of Kyungbu expressway to Sangdang park and was thought to have a peculiar characteristics. This main entrance road was seperated into 4 parts according to arranging patterns of roadside trees and buildings. To investigate the visual characters, the sementic differential scale experiment was used. The visual characters, the sementic differential scale experiment was used. The visual preference was examined by analyzing visual volume of 4 factors. The results of the study based on these analyses were as below : 1. Factors that compose the visual characters of roadscape were classified by the emotional factor, the individual factor and the physical factor. These 3 factors showed a64.14% total variance. Among 3 factors the emotional factor which represented psychological reaction was appreciated to be the highest and the physical factor was assessed to be the lowest. 2. 24 items in total 14 adjectives showed the following ranking of mean values in sementic differential experiment : Road I -->RoadIII-->RoadII-->RoadIV. The mean values between Road I and RoadIV showed a significant difference, which can be explained to be a contrast between the natural factor and the artificial factor. 3. The mean value of the visual preference was the highest at Road I and the lowest at Road IV. While Road II and Road III showed 3.51 and 4.71, respectively. 4. The effect of 4 factors on visual preference was analyzed by regression as follows : Visual preference =1.2983+0.0627 + 0.0230+0.0203, R-Square=0.5

  • In this work, epoxy/carboxyl-terminated butadiene acrylonitirile (EP/CTBN) composites were prepared by employing a reinforcing filler, silica treated with silane coupling agent in different ratio by dry and wet method. Their curing characteristics, surface free energy, interface morphologies and mechanical properties such as tensile strength and impact resistance were carefully investigated. Differential scanning calorimetry(DSC) results showed that curing temperature was lowered with the increase of silane coupling agent because of the increase of relative curing agent cotent by filling the pores of silica. Wet method was proved to be more effective for lowering curing temperature of EP/CTBN composite. In general, surface free energy and impact resistance were increased with the increase of silane coupling agent in this work. Tensile strength, however, was observed to be decreased at 4 wt% of silane coupling agent. It was found that the dry method was proved to be preferable for pretreatment of silica with coupling agent.

  • The development of pale chub oocyte from the immature oogonium to mature oocyte was investigated by light and electron microscope. The cytoplasm of pale chub oogonia was acidic and many vesicles were located at inner side of nuclear membrane. In primary oocytes, yolk vesicles were distributed in cytoplasm. Also, fibrous materials and protuberances were distributed on the surface of zona radiata. The nucleus of secondary oocyte was enlarged and yolk vesicles in cytoplasm migrated to zona radiata. In early egg, yolk mass are formed and yolk vesicles were located at inner side of zona radiata. Three-layered zona radiata was about $3{\mu}m$ in thickness. The three layers were an outer fibrous material layer, a middle nurse cell layer in which microvilli of early egg cytoplasm contact with processes of nurse cells, and an inner layer with high electron density. In mature egg, euchromatin and a germinal vesicle were developed, mitochondria, free ribosomes, and yolk mass were distributed in cytoplasm. But, yolk vesicles were disappeared. Specially, zona radiata of matured eggs were better thin than the one of immature eggs In conclusion, it is summerized that the oogenesis of pale chub were the increase of cell size, the formation and accumulation of yolk, the decrease in nucleat electron density, changes of zona radiata, and the development of microvilli.

  • A novel 200 MHz CMOS transconductor using translinear cells is proposed. The proposed transconductor consists of voltage followers and current followers based on translinear cells and a resistor. For wide applications, a single-input single-output, a single-Input differential-output, and a fully-differential transconductor are systematically designed, respectively. The theory of operation is described and computer simulation results are used to verify theoretical predictions. The results show that the fully-differential transconductor has a linear input voltage range of ${\pm}2.7$ V, a 3 dB frequency of 200 MHz, and a temperature coefficient of less than 41 $ppm/^{\circ}C$ at supply voltages of ${\pm}3$ V. In order to certify the applicability of the fully-differential transconductor, A ladder-type 3th-order cllitic low pass filter is also designed based on the inductance simulation method. The filter has a ripple bandwidth of 22 MHz, a pass-band ripple of 0.36 dB, and a cutoff frequency of 26 MHz.

  • This landscape design is a work for which we selected the square of Sejong Center for the Performing Arts as a object area, drew inhuman factors, and tried to restore them to human environment. This plan assumes that excessive urban environment results from disorder and man can keep it in order and restore it to human environment through the progressive process of speculation. In this plan, we included the least parking space and nearby roads in the object area to maximize the location feature and the symbol of cultural space, and planned that the object area may play its role of open space in the downtown. To grant the symbol of culture space, we established the progressive process of speculation and the relationship of mu, heaven and earth, and culture, geometrically diagrammatized it, combined the circular and rectangular lines derived from it, and suggested a plan. Urban environment will continue to change in the future. However, as long as it is not ensured that the change will progress upward, city would be far from human environment anyhow. Effects to display inhuman space overlooked in the downtown and restore it to human environment for citizen and location for man, should continue.

  • The Seomoon Bridge, a new planning site, is located in Sangdang-Gu Seomoon-Dong, Chongju and is the oldest bridge built during the rule of Japanese imperialism. As the name implies, Seomoon Bridge is located on the site adjacent to west gate. The Seomoon Bridge is an important bridge as an historical trace of the vanished town of Chongu. However, as new roads and bridges are built, the Seomoon Bridge is losing its functional aspects and has become an area crowed by many street stalls. Closely located newer to Sajic Fountain, the Seomoon Bridge, which has symbolically significant meaning, now faces many problems such as non-practical use of bridge, indifferent management and non-locality, which creates a negative effect on the surrounding cityscape. given this situation, in 2001, 2, Chongju city published an appeal for public subscription of a practical use plan which may design a new, landmark and establish resting spaces for the public. The basic direction of this planning is designed to be place as the symbolic space representing Chongju, and integrated with the surrounding environmental elements such as Moosim-Cheon(stream) and Sajic Fountain, and as a recreational, resting and leisure space of the public. Especially nightscape of the bridge inspires a fresh impact on many people. Because of the widespread influence of developed cities, diverse spaces which already exist or have disappeared may be reclaimed. By establishing appropriate use plans rather than negligence, this project will propose the improved quality of cityscape and show the possibility of bublic´s outdoor living space, and our team will find out the meaning in these approach methods.

  • The characteristics of Peyssonnelia capensis Montagne (Peyssonneliaceae, Rhodophyta) from Jeju Island were investigated in order to clarify the species entity and re-evaluate taxonomic position. The morphological variations of the Peyssonnelia capensis from Jeju Island were divided into two types, the thin thallus type and the thick thallus type. The thin thallus type is characterized by thin, soft, orbicular, slightly lobed thallus with entire to undulate margin, and compact rhizoids. The thick thallus type has thick and stiff thallus with sinuate margin and scattered rhizoids, and has more branches than the thin thallus type. The basal layer and the epithallium of thin thallus type are similar to those of thick thallus types in their structure. However, the hypothallial cells of the thick thallus type are longer than those of the thin thallus type. The erect filament of thick thallus type has more cells than those of the thin thallus type. Tetrasporangial nemathecia are distinctly protruded. Mature tetrasporangia of this species are divided cruciately into four spores as those of other Peyssonneliaceae. In addition to their morphological and anatomical distinctness between two types, the nucleotide sequence analyses of SSU and ITS2 region make no differences among populations from Jeju and other localities in Korea. Therefore these two morphological variation may not base on genetic variation.

  • Modern companies are trying to find out the core value of companies' competition to survive at the suddenly changing market by finding several kinds of consumption. This is also getting more serious in the case of the department stores and their mutual relationships are seen getting more warlike. On the occasion of the department stores, the reduction of the cost and the expansion of profits are the methods of short survival, however these have some danger that depreciate the quality level of the service produced to clients. Therefore, for the department stores, the establishment of strategic plans for the service can be said that the most important strategy of superior achievements of competitions. At this point, the purpose of this study is to abstract the service quality facts for the diversified customers' needs and find for possibilities of application at the service marketing strategy through an actual analysis by examining department stores in Chongju.
