In this study, we identified wood species used in manufacturing Streetcar No. 381 from Seoul Museum of History. This Streetcar No. 381 is an important cultural heritage as one of the 2 streetcars remained in Seoul. It is important to preserve this streetcar through restoration and to maintain without any damage or degradation. The information on species of wood members should be needed for its original restoration. Thus, 6 interior and 1 exterior wood members were sampled and identified microscopically. Among the 7 wood members identified, 2 were found to be douglas-fir ($Pseudotsuga$), 2 lauan ($Shorea$), 1 exotic hard pine of ponderosa group ($Pinus$), 1 larch ($Larix$), and 1 oak of cerris group ($Quercus$), respectively.

In comparison with different mass transportation systems, the streetcar is lower, both in speed and transportation capacity. However, it has the advantage of reducing the cost of construction, because it makes infrastructure simple, by using the road. It is proper in the city, where the population is few, to raise the efficiency of traffic. The convenience is high to passengers. On time accuracy and the commercial speed is influenced by operating condition. Generally that is organized into 21m degree in 6 quantity. All passengers in a streetcar are about 180 people. The maximum speed is 40~60km/h. When road traffic is considered, the speed can be reduced to 15km/h. To enhance the speed, the construction of a priority signaling system is necessary which is integrated with the road traffic operation information system. In order to develop a better Traffic Control System which is connected to a Traffic Control Center, a Priority Signaling System which incorporates Intersection Control Technics must be included.

This paper attempts to re-read Tennessee William's A Streetcar Named Desire from a non-Aristotelian perspective, particularly focusing on the audience performativity. In Chapter 6 of the Poetics, Aristotle says that tragedy has a final purpose or end (telos) and that is to inspire a catharsis (literally "purification") of pity and fear by means of representation and to give pleasure from experiencing their relief. However, a dramatic theoretician Augusto Boal argues that Aristotelian catharsis is not to get rid of pity and fear through their vehement discharge; rather, the basic function of catharsis is the purging of antisocial elements from the social body and the restoration of order because catharsis occurs when the spectator, terrified by the spectacle of the catastrophe, is purified of his "hamartia" which looks similar to the tragic flaw of the hero in the play. Thus, Boal asserts that Aristotle's coercive system of tragedy manipulates the emotions of the passive spectator. By contrast, in non-Aristotelian aesthetics, tragedy functions not as legitimation for a particular political configuration but as the performance of ethical acts-through which all the participants, including not only the actors but also the audience, communicate more actively about practical problems and actively work in order to make sense of themselves, others, and society. Here, the audience is required to restore and reinforce his/her capacity to think and to act; thus, an unquestioning, passive, indifferent attitude is not allowed. In these contexts, this paper explores how Tennessee William's A Streetcar Named Desire involves the audience in the responsibility for what occurs on the stage, in order to urge the audience's ethical judgements and responsible acts. This paper argues that what this play asks of us is not catharsis, the purging of pity and fear, but empathy toward the other's pain, beyond pity and fear, to carry out our responsibility of sharing in and caring for the other's suffering. That is to say that it will be an ethical way to "re-member" Blanche DuBoi-the iconic Williams victim "dis-membered" by traumatic memories and open wounds and is thus unable to complete her grieving and mourning-as one of us, not as the other. It will be the only way to remember right regarding her tragedy.

Electric railway system consist of rolling stock, track, signal and streetcar line system. ATP(Automatic Train Protection) system in railway signaling system is the important one grasping the position and velocity of a train. The wayside transmitter of ATP system is installed between rails. Recently, the research about increasing train speed has been developed in total departments of the railroad systems. The study on the information transmission between on-board transmitter and wayside transmitter is required for increasing the train speed in the ATP system. When the train speed is increased as to same transmissi on distance, the problem on information transmission occurs because the transmission time is decreased. In case that the transmission distance is extended, the transmission time is decreased with respect to the train speed. Therefore, we have to define the standard magnetic intensity as to the train speed in order to transmit correctly telegram. In this paper, the transmission distance for the telegram is suggested on the basis of the train speed. Also, the standard magnetic intensity from the wayside transmitter to on-board transmitter is proposed by using transmission distance regarding the train speed in the ERTMS/ETCS system by using Matlab program.

The purpose of this study is to evaluate the influence of T-shirt as a movie costume on the modem mass fashion. The way of study is to analyze the changes of men's image with T-shirt as Hollywood actors costume in 50's and 60's. The costumes create the characters with meanings and symbols moreover they lead fashion as well as promoting artistic value of films. At the end of the 19th century, this shirt learnt the ropes in the U.S. Navy well before it won the hearts of sportsmen and workers alike, with its twin virtues of comforts and hygiene. When American soldiers returned home after World War II showing their T-shirts in the sweltering heat of the Tropics, their shirts were as heroic as they were. Furthermore the new stars of Hollywood, going by such names as Marlon Brando and James Dean, gave the T-shirt its rebel cachet and showed the whole world. Be it tom open on Marlon Brando's torso in Elia Kazan's 'A Streetcar Named Desire', or peeping out dazzlingly white from under James Dean's red jacket in 'Rebel Without a Cause', the T-shirt flaunted its sexuality and emanated the sweet smell or revolt. It would be the banner of rebellion for a whole generation. The T-shirt had finally found its way into the history of fashion and was there to stay.d was there to stay.

Electrical railway system consists of rolling stock, track, signal and streetcar line system. Track circuit system is a vital system due to checking the location of trains. Track circuits are divided by using frequency and isolated electrically. Currently, there is not a regulation for the distance between track circuits using identical frequency. In case of installing additional track circuits in large stations or marshalling yard, the problem which is that the signal is not exactly transmitted to the track circuit occurs due to the mutual interference. In other words, the track circuit properly is not operated on account of wrong induction current by the mutual inductance between track circuits. In this paper, we suggest the electrical model between track circuits and numerically calculate demanded parameters in electrical model. The distance between track circuits satisfying the mutual inductance which does not happen to the mutual interference phenomenon is presented about the distance of track circuit. It is proved by using Matlab and PSpice program as the amplitude of mutual induced current.

Recently, fast-growing up railway transportations. Because, regional traffic congestion problem solving and a period of rapid expansion to meet the demand of industries. In addition the government also suggest to new paradigm for the future 'Low Carbon, Green Growth' is presented as a new national vision. To meet the social needs and the time demands, Last of the railway increase very long tunnels and huge deep tunnels. Especially this trend accelerated high speed up in the tunnel, the revision of design criteria and research challenges are being actively improved. Mainly in the tunnel cross-section was under the control of the vehicle train speed 150km/hr by the construction of the vehicle cross-section of the tunnel. More than 200km/hr rail tunnel depending on the vehicle's speed caused the tunnel to the pressure fluctuations will be governed by the aerodynamic changes. Considering the economy to ensure the optimum cross-section of the railway tunnel to the description scheme is selected cross-section of the railway tunnel to determine the size domestic or international railway tunnel for the elements((based on fast Algorithm design criteria, the center line spacing, streetcar line, cross-sectional shape, sectoral issues, such as interface and aerodynamics) based on design practices and to review results. In this study, to propose guidelines depending on the size of a railway tunnel cross section for the size of the determining reasonable factors when designing the railway tunnel and cost-effective standards guidelines.

Trams are rail vehicles that run on tracks along public, urban streets; they also sometimes run on separate rights of way. Tram vehicles run more efficiently and their overall operating costs are lower than those of similar vehicles. In general, trams provide a higher capacity service than buses. However, when tram stops in the middle of the road do not have pedestrian refuges, trams can cause speed reductions for other transport modes (buses, cars), as in such configurations other traffic cannot pass whilst passengers are alighting from or boarding the tram. In this study we examined the qualifications of overseas tram operation. The Railway Safety Act, sub-laws, and other relevant laws were examined to determine complementary measures.
