This thesis is about design spirit demanded by the 21st century vehicle design studied in consideration of city commuter. First of all, going over the transition of the last century vehicle design led to the arrangement of the changes in vehicle models. Even though the invention of vehicles brought about immense improvement in living standard of the people, it also brought about other factors that were harmful for human living. Through this realization the main fact that should be emphasized is that the vehicles in 21s1 century should not be a threat to the human life or be the main cause for the environmental pollution of the earth. With the question as to whether the vehicles development direction at the beginning of the year 2000 like the Retro design and Hybrid-Compact car development is appropriate to these demands, the development of City Commuter vehicle (the most human and environment-friendly concept which can also serve as the connecting means in transportation system) and its case studies were compared. Through this, the design spirit that should be inherent in environment and vehicle human and vehicle relationships and the design factors needed for the continuous development of the vehicles were arranged.(classified) Rather than suggesting a new direction for the specific style for vehicle design, this thesis is to emphasize that to improve the standard living of the people with vehicle as a product that will be continually produced in the 21st century, the morals and the mission of the designers about the environment and humanity recovery should be the core of the active movement and education of vehicle design.

Modernization of Korea had begun with the reformation of the Kab-o Reform in 1894, which the government had designed after the protectorate treaty with Japan in 1876. It had affected drastic changes on the formation and framework of a Han-bok by government and the main changes is found in creating new style of Gae-ryang Han-bok. During 1980's, the peoples were interested in traditional cultural heritage, and 'the campaign of wearing Woo-Ri Ot' prevailed in Korea to instill the radical sprit of Korean. A Han-bok, which was made at this time, has called a Saeng-hwal Han-bok. The purposes of this study are to defue the the words that are Han-bok, Gae-ryang Han-bok and Saeng-hwal Han-bok of meaning and characteristic based on the previous studies and historical materials and present a unified and historical opinion about Han-bok to the academic world and industry of Han-bok by the consideration. Han-bok is a traditional costume with a long skirt and long breast-tie based on the later Cho-sun and is emphasized a virtue and manner on it. Gae-ryang Han-bok is an improved Han-bok that is include with a Tong-Chima and Jeogori for making a movement and function better. Saeng-hwal Han-bok is originated by the movement of wearing Woo-ri Ot in 1984, is interpreted the traditional Korean beauty from the modem view and is a practice Han-bok for popularizing intodaily life. After investigating the 33 of previous studies, the characteristics and transitions of Han-bok are followed. First, the reason of fail about the reform of dress is a loss of traditional beauty. Second, the yes or no of the establishment of law about the reform of dress, it influenced on a reforming or wearing speed of costume. Third, after 8.15, a modem girl and girl student can not impact on a system of Korean women anymore because, the number of the group that means a high educated and active woman, was growing. So, the elevation of women's education matured the system of Korean women's costume. forth, western style clothes are popularized after the Korean War and it is set down in the system of Korean women's dress.
This study was conducted to control unseasonable flowering in a standard chrysanthemum 'Baekma' bred in Korea by 2-chloroethylphosphonic acid (ethephon) and night temperature (NT) through suppression of the transition from a vegetative to a reproductive stage under long day length caused by high NT in summer season. Ethephon was applied either once or twice at a concentration of 0, 200, 400, or $800mg{\cdot}L^{-1}$. The NT within controlled mini-plastic houses was maintained at 13, 17, or $21^{\circ}C$. The NT at $13^{\circ}C$ showed the greatest inhibiting effect of unseasonable flowering among all NTs regardless of various combinations of ethephon concentration and frequency. Moreover, the inhibition tendency of unseasonable flowering was distinctly decreased in a NT-dependant manner. Higher NTs reduced cut flower length and number of leaves, but increased the number of young leaves attached to top part of the flower. Higher ethephon concentrations and lower NTs increased cut flower length and the fresh weight of total, stem, and leaves due to the extension of vegetative growth period. Thus, if it is difficult to control the NT below $21^{\circ}C$ in greenhouses in the summer season, we recommended to spray more than $200mg{\cdot}L^{-1}$ ethephon once after planting to suppress unseasonable flowering and to ensure sufficient length of cut flowers.

As the interest in the positive quality of life is increasing throughout the world, the number of people who are suffering from negative sentiments, such as depression, anxiety, or stress, is increasing, as well. Especially, the adolescence period is the period of transition from childhood to adulthood and accompanies significant changes in terms of the body and mind alike. The purpose of this study is to examine the negative sentiment of the juveniles, caused by the stress they experience in their social and personal domains and the distress tolerance that can protect the inner feelings of them at the same time, to understand how they are related to the subjective well-being of the juveniles. For this study, the researcher employed the data from 362 high school students from the high schools located in Seoul and Gyeonggi area, which were analyzed using the statistics suites SPSS 22.0 and AMOS 22.0. According to the findings of this study, first, the depression and anxiety of the adolescent population showed a significant relationship for each variable with regard to the distress tolerance and the subjective well-being. Especially, the negative correlation with the subjective well-being was highly significant. Second, the depression and anxiety of the juveniles turned out to influence the distress tolerance and subjective well-being of them in a negative manner. In both distress tolerance and subjective well-being, the influence of anxiety was higher than that of depression. Third, in the relationship between depression, anxiety, and subjective well-being, the distress tolerance turned out to have a mediating effect. Such results of this study provided the basic data for suggesting the strategies to promote the perceived psychological well-being and help the juveniles who are under stress.
Active debris removal, a technology that approaches and removes space debris in orbit, and the on-orbit service, a technology for extending the mission life of satellites by fuel charging or by exchanging the battery, are gaining interest with the growth of the space community. SaTReC plans to develop a satellite capable of capturing and removing Korean satellites orbiting in space after the end of their missions. In contrast to the previously launched satellites by Korea, which were mainly intended to observe Earth and the space environment, rendezvous/docking technologies, as required in the future during, for instance, space exploration missions, will be implemented and demonstrated. In this paper, an orbital transition method for next-generation small satellites that will capture and remove space debris will be introduced. It is assumed that a small satellite with a mass of approximately 200 kg will be injected into the mission orbit through Korea Space Launch Vehicle-II in 2027. Because the satellite must access the target using a minimum amount of fuel, an approaching technology using Earth's J2 perturbation force has been developed. This method is expected to enable space debris removal missions for relatively lightweight satellites and to serve as the basis for carrying out a new type of space exploration in what is termed the 'Newspace' era.
The samples used in this study were collected on two occasions (April 21 and May 16, 2021) from Liobagrus mediadiposalis and spawned egg masses located under rocks in Daeseocheon, Yeongdeok-gun, Gyeongsangbuk-do. Fertilized eggs ranged in size from 3.30~3.92 (average 3.57±0.19) mm (n=30), and it took 152~155 hours to hatch at water temperatures of between 17.0 and 20.0℃. Newly hatched larvae immediately post-hatching had a total length of 6.43~6.67 (6.55±0.07) mm (n=30), and were characterized by the retention of a yolk sac and an incompletely open mouth and anus, consistent with the yolk. On the 9 days post-hatching, the postflexion larvae had grown to length of between 11.0~13.8 (12.3±0.70) mm (n=30), and the caudal bone at the tip of the tail was bent upwards at an angle of 45°, thereby indicating the transition to the late larval growth stage. On the 16 days post-hatching, the total length of juvenile had increased to between 15.8~18.2 (16.8±0.77) mm (n=30), and the number of fins reached a fixed number of 8 dorsal, 17 anal, and 8 pelvic fins. On the basis of the findings of this study, we were able to confirm differences in the size of hatching larvae and fin mottle patterns in the early life history of related species.
With transition to Knowledge society and introduction of information industry, there are many companies which have higher stock price than the suggested value from its financial information. To explain similar cases in capital markets, many researchers focus on non-financial information such as Web Traffic data or intangible assets such as intellectual property rights rather than traditional financial analysis. Besides, the relationships between financial and non-financial information with firm value are changed according to industry lifecycle. As Industry grows, financial information of company is more important for firm valuation in Capital market. We'd like to review the changes of relationships between financial information and firm valuation in Capital market especially for "Software", "Digital Contents", and "Internet" companies listed in Kosdaq market during 2000~2011. The result of data analysis shows the financial information gets more important after 2007. Inversely, it provides analytical bases that related industry gets mature. Also we show that intangible properties are more relevant to stock price of those technical based companies than others.

This Paper describes algorithm to extract license plates in vehicle images. Conventional methods perform preprocessing on the entire vehicle image to produce the edge image and binarize it. Hough transform is applied to the binary image to find horizontal and vertical lines, and the license plate area is extracted using the characteristics of license plates. Problems with this approach are that real-time processing is not feasible due to long processing time and that the license plate area is not extracted when lighting is irregular such as at night or when the plate boundary does not show up in the image. This research uses the gray level transition characteristics of license plates to verify the digit area by examining the digit width and the level difference between the background area the digit area, and then extracts the plate area by testing the distance between the verified digits. This research solves the problem of failure in extracting the license plates due to degraded plate boundary as in the conventional methods and resolves the problem of the time requirement by processing the real time such that practical application is possible. This paper Presents a power automated license plate recognition system, which is able to read license numbers of cars, even under circumstances, which are far from ideal. In a real-life test, the percentage of rejected plates wan 13%, whereas 0.4% of the plates were misclassified. Suggestions for further improvements are given.
'Creative Economy' has been announced as the new paradigm of socio-economic development strategy of newly elected President Geun-Hye Park's administration. By explicitly defining people as a major player in creative activity, it seems to depart from expert-driven or science & technology-focused development paradigms of previous administrations. Yet, its interpretation and operation in terms of government policy does not seem to show any differences. This study aims to explicate the nature of Creative Economy as a development paradigm by clarifying the differences between people's creativity and that of scientists and engineers through extensive literature review. People can contribute to the creative activity not just as users but also as living persons who make everyday yet independent choices based on their humanistic, philosophical, ethical and experiential capabilities which are clearly different from the sources of scientists' & engineers' creativity. People's creative activity does involve value judgement about life and can often accelerate the system innovation or transition by changing consumer behaviour and lifestyle, and hence destruct technological lock-in user lock-in of the existing system. People's creativity can thus present 'User/Field-driven Innovation Paradigm which clearly differs from existing expert- or science & technology-driven innovation paradigm. The Creative Economy with focus on people's creativity therefore faces new socio-economic development challenges of fulfilling the User/Field-driven Innovation Paradigm.

In this study, the efficiency of photosynthetic electron transfer according to LED color temperature was verified in order to find a way to efficiently grow trees under night illumination. The experiment was carried out with White treatment, Warmwhite treatment, and non-treatment with donarium cherry. The study uses to a method for analyzing and evaluating the color temperature of an LED light source by photochemical analysis. We found that all treatments 115 DAT of maximum fluorescence amount(P) had the lowest. In the treatment using white light and the Warm-white light, the T amount of florescence of the late stage during the transition of the J-I level was increased, and the photosystem I electron transfer efficiency was decreased. Therefore, the electron transport efficiency of $RE1_O/CS$ and RE1o/RC were reduced. Especially, compared to Warmwhite, the light intensity increased greatly in the white-light treatment, The $PI_{TOTALABS}$ of 7 DAT was the highest value, but it was decreased to the lowest value on 115 DAT. This study has shown that the white treatment was low in electron transfer efficiency and soundness. Warmwhite-light treatments showed lower stress.
