The purpose of this thesis is to study the formative characteristics and symbolism shown in Rock stars' hairstyles through rock music to have influenced youth culture. There were a D.A style and a mop top style which included the youth characteristic to seek a new desire and value as the hairstyles of Rock & Roll stars, along with the characteristics of Rock & Roll music to represent the feeling of teenagers in 1950's at that time unlike the previous music due to high beats mixed with Rhythm & Blues (R & B) and Country music, and use of electronic guitars. We can see the desire for challenge and freedom against the then present regime, shouting love and peace, and resistance in the Psychedelic Rock music stars' hairstyle, which are untrimmed and disheveled, that is, natural. We can find explosiveness in Mohican and Spike style of Punk Rock stars playing fierce and aggressive music, along with words including indignation and assertion against the society's regime. The Artistic characteristic is implied in the following hairstyles: Glam Rock stars' hairstyle, a man's long-haired but a little long crew-cut style to reduce the bulky feeling and to give a bisexual, visible shock with hair dyed in orange to emphasize magnificence, and Punk Rock stars' hairstyle showing beauty in their own way with expression of anti-beauty to intentionally look ugly. Like this, the 20th Century's Rock music and youth culture are closely associated each other, and showed a new style, and played a leading role in street fashion, which became a momentum to much influence high fashion as a look of the 20th century modern fashion.

The small wind generator with existing mechanical control system has a frequent failure and malfunction, and its maintenance is difficult. In this paper, an electric control method using a boost converter for small wind generator was suggested. The suggested 2-level boost converter control device was manufactured and its experimental operation were conducted on a wind generator with 200 [W] capacity. As a result of experimental device, the control by a boost converter was executed at the point that the output voltage of a wind generator became 36 [V] so it could be identified that the output voltage of a wind generator diminished and then it became 0 [V] after 5 [sec]. Besides, in case of applying the method suggested in this paper to a small wind power generation facility for street lights, it is expected to reduce its maintenance by preventing a frequent failure of a generator and to improve its utilization rate.

The width of sidewalk is one of the important factors constructing a pleasant pedestrian environment. The procedure for sidewalk width design based on the Level of Service is suggested in Korea Highway Capacity Manual. However, this manual does not give a difference between the sidewalk on the street with the passage of the subway, therefore, the different flow characteristic of these places is not appropriately reflected. Though the pedestrian flow in the subway encounters a frequent stop and go situation as like the platoon of vehicles, the similar condition is rarely observed at the urban streets. The new measure of LOS for sidewalk is in need. The study reviewed the prominent measure of LOS and carried out the outdoor experiment to evaluate the new measure. Particularity, GPS was used to collect the pedestrian foot path trajectory for the quantitative evaluation and the results from quantitative and qualitative are compared.

This paper proposes a new noise suppression method using the Wavelet transform analysis. The noise suppressor using the Wavelet transform shows the more effective advantages in a babble noise than one using the short-time Fourier transform. We designed a new channel structure based on spectral subtraction of Wavelet transform coefficients and used the Wavelet mask pattern with more higher time resolution in high frequency. It showed a good adaptation capability for babble noise with a non-stationary property. To evaluate the performance of proposed noise canceller, the informal subjective listening tests (Mos tests) were performed in background noise environments (car noise, street noise, babble noise) of mobile communication. The proposed noise suppression algorithm showed about MOS 0.2 performance improvements than the suppression algorithm of EVRC in informal listening tests. The noise reduction by the proposed method was shown in spectrogram of speech signal.

Location awareness is one of the key functions to build U-city. Recently, many of works for location-aware systems are emerging to commercially apply to on-going large-scale apartment complex. As dwellers or cars being attached with active tags are moving in the U-city complex, the active tags periodically broadcast their own identifiers mu routers fixed along the street or in a building use those information to calculate location of thorn. There are several issues to be considered for such an environment. In this paper we propose i) a new architecture for location-aware system considering such issues ii) technical issues to implement it using active tags, and iii) a mathematical analytic model to investigate overall performance and verify it by comparing with actual experimental results. Through mathematical analysis, we can show that it is more efficient for the routers to send location signals than the tags do. We also show that there are several additional services available in the apartment complex. We conduscted several experiments hi a real ease parking lot to show that our system can locate the location of dwellers or cars.

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 purpose of this study is to assess residents' perception of the revitalization projects of the rural center and to evaluate their views of the projects' importance and their levels of satisfaction with how they have been carried out. In this study, we measured the residents' perceptions and preferences regarding these projects by using Importance-Performance Analysis (IPA). Results showed that residents' perceptions and satisfaction were the highest for the projects providing welfare facilities, even though this project has little relevance to the overall project goal. Residents were dissatisfied with construction projects such as the building of cultural facilities and urban parks, even while recognizing their importance. It is necessary to establish what problem the people perceive and to manage them appropriately. Next, the residents did not appreciate the community empowerment projects, nor did they evaluate the contents of the program positively. It can therefore be seen that the community empowerment projects have not been carried out well. Finally, the street landscape improvement project was not successfully implemented compared to other projects. The residents have negatively perceived the installation of facilities that they do not want, rarely use, or are poorly operated. this shows that the evaluation of residents is significant. They become the users of the revitalization project for the rural center. It is necessary to overcome problems such as project items chosen by professionals without local consultation and obvious design in the revitalization project of the local center. There is a need to ascertain the residents' opinion of each project and to encourage them to participate directly in the management operation.

The purpose of this study is for consideration of the flapper fashion (1924-1928) in Jazz Age (1919-1929) of America and the influences of it on modern fashion. This study is started from the latest fashion trend which is pursuing it's inspiration into the Jazz Age, the 20s. The etimology of 'flapper' was based on mines is 'flap' such as 'flutter of skirt hemline', 'hands', 'arms', 'wings' and a slang which was applied to young women from 1830. In 20th century it has meant not only new American women but also their fashion and attitude. The designs of flapper fashion were expressed by simplicity, functionality, nudity and rhythm. Simplicity was the best value of this time and the simple image was considered the smartest. Functionality was represented by straight boyish style and loose baggy silhouette that was related to free dome. Nudity was expressed by revealing of legs, arms, backs in shapes and see-through by materials. It was related to sexual attraction and point to youth. Rhythm of flapper fashion expressed optical effect of movement. Using of light material was deep related to freedom of flappers, speed, rhythmical Jazz and dancing. The influences of flapper fashion were giving an opportunity that changed fashion leader from high class to young popular group and simple design of flapper fashion effected to modernization and popularization of American apparel business. And it influenced American casual fashion which was known as brightness, youth and openhearted mood. So flapper fashion can be reganded as the starting point of the street fashion of the 20th century.

The travel behavior should be analysed microscopically for the traffic management of urban street. The car following theory which found out the correlation between the lead and the following vehicles is being widely used as basic data in many fields. As the vehicle position and its speed information can be received by GPS, this technique is recently applying to the various fields. For the case study the travel data were collected with two vehicles equipped with GPS receiver. The moving distance was calculated by the collected location data every 2 seconds and the speed variation was checked. And this study analysed and compared the acceleration and deceleration speed between the lead and the following vehicle. Finally, Regression model about the relationship between the acceleration and deceleration speed and the acceleration and deceleration distance was constructed. This model could be helpful for the road design and the regulation for the safe traffic management.

This study is to develop cultural products based on 'Jeju Choga', which means the traditional houses in Jeju. For the product development, old literature review, field surveys, and consumer surveys were employed. Through old literatures and field surveys, the unique and visual characteristics of Jeju Choga were confirmed: A thatched roof with lattice pattern, a side wall and fences with porous stones, a 'Jungnang' serving as a gate, and a 'Pungchai' preventing strong sola radiation and 'Ollai' meaning a narrow street in front of the Choga. As a results of consumer survey conducted before the development of products, consumers highly recognized and associated Jeju Choga as Jeju representative image. The six basic patterns of Jeju Choga were drawn and eight textile designs were created through the repeated arrangements of the basic patterns. Using the created textile designs and digital printing method, the eleven new fabrics with the patterns of Jeju Choga were developed. The various kinds of ten bags and tow wallets made with the new fabrics. As a result of consumer evaluation for the twelve products made in this study, the scores of preference and purchase intention were above the average work for the most products of them. In particular, the preference and purchase intention of the square shoulder bag, the big-size shopper bag, and the small-size cross bag were very positively evaluated. Therefore, it is confirmed that Jeju Choga could be very useful as a motif for the development of cultural products focusing on Jeju tourism souvenir market.
