The expansion of the physical road in response to changes in social conditions and policy of the country has reached the limit. In order to alleviate congestion on the existing road to reconsider the effectiveness of this method should be asking. Currently, how to collect traffic information for management of the intersection is limited to point detection systems. Intelligent Transport Systems (ITS) was the traffic information collection system of point detection method such as through video and loop detector in the past. However, intelligent transportation systems of the next generation(C-ITS) has evolved rapidly in real time interval detection system of collecting various systems between the pedestrian, road, and car. Therefore, this study is designed to evaluate the development of an algorithm for queue length based real-time traffic signal control methodology. Four coordinates estimate on time-space diagram using the travel time each individual vehicle collected via the interval detector. Using the coordinate value estimated during the cycle for estimating the velocity of the shock wave the queue is created. Using the queue length is estimated, and determine the signal timing the total queue length is minimized at intersection. Therefore, in this study, it was confirmed that the calculation of the signal timing of the intersection queue is minimized.

During the 2000s there were changes in the educational facility policy having impact on school architecture, such as departmental classroom system by the 7th national curriculum and BTL projects. Especially for secondary school architecture with the new keyword of 'departmental classroom system' unlike elementary school with the well-known keyword of 'open classroom', the emergence of new school architecture was anticipated. For these reasons it is worth while to notice secondary school architecture in the 2000s and this study aims to review the architectural characteristics of middle schools as first step. Cases of 18 schools selected by EDUMAC were analyzed focused on site planning and planning characteristics of each spaces. Through the analysis, the architectural characteristics of middle schools in the 2000s are summarized and comments on some problems are made. In summary, case schools have typical characteristics of Korean school architecture in unit classrooms and block plan for daylight condition. On the other hand, they have more diversity in space organization and facility program. But it leave something to be desired in expressing urban architectural characteristics, traditionality and locality with searching for new school architecture.

Because sensing odor varies depending on each person, even if the odor is released in line with the legal emission permission concentration levels, it can still become a social issue if a civil complaint is made. The purpose of this research is to study the possibility of putting Mn-Cu metallic oxide catalysts into practical use to economically eliminate acetaldehyde which produces a odor in the industrial process. An optimal operating parameter to eliminate acetaldehyde was deduced through a performance evaluation in the research laboratory and the performance was verified by applying the parameter into an actual facility as an on-the-site experiment through a Scale-up of pilot size. The operating temperature of the metallic oxide catalysts researched so far was at the minimum close to $220^{\circ}C$, and the $220^{\circ}C$ elimination efficiency was 50% or below. However, having experimented by using a Mn-Cu metallic oxide catalyst in this research, optimum elimination efficiency showed when space velocity (GHSV) was equal to or below 6,000 $hr^{-1}$. The average elimination efficiency was 61.2% when the catalyst controlling temperature was $120^{\circ}C$, 93.3% when the catalyst controlling temperature was $160^{\circ}C$, and 94.9% when catalyst controlling temperature was $180^{\circ}C$, thereby reflecting high elimination efficiency. The specific surface area of the catalyst was $200m^2/g$ before use, however, was reduced to $47.162m^2/g$ after 24 months and therefore showed that despite the decrease in specific surface area as time passed, there was no significant influence on the performance. Having operated Mn-Cu metallic oxide catalyst systems for at least two years on a site where there was no inflow of toxins like sulfur compounds and acidic gases, we were able to confirm that elimination efficiency of at least 90% was maintained.

This study tried to analyze symbolism of the work from the title by looking into its linguistic meaning. The title not only exposes artist's thoughts but also speaks for the work subject. Also, it designates the world composed of characters in the work, and further it can be said as endowing overall meaning on the entire work by suggesting possibility of limitless meaning invention as well. As a result of reviewing the symbolism shown at the title after analyzing such points through linguistic contexts, the title named with Adam's language was used for just expressing the essence of characters in the work by transcending time and space, and the title meaning exposed relational aspects between characters and occurred accidents through the association process on 'signifiant' and 'signifie.' These relational aspects are expressed to mutual contraposition, but their relations finally show another one orientation too. In case of the title made by the arbitrary nature of language, a fact could be known that it was results of customs completely unrelated with the practical work and depended on the experience by any accident as being appeared from cultural background of the country where the work was produced. Also, the signification of language occurred in unique regulations and systems, and it was relevant to seeing things through concepts. The proper noun was disappeared, and the symbolism was given again from relational aspects accordingly. It was turn out that similarity between the work and title contained contents of entire work, and played a role of expressing greed in the narrative briefly.

The work to be analyzed in this study is an animation showed in 2006, which was made by Director Satoshi Kon on the basis of a Japanese SF novel written by Yasutaka Tsutsui. The key point is to create a new meaning through showing imaginative power of audiences from the world flying across the borderland between reality and fiction. It regarded suitable for analysis of the borderland appearing in the unconscious world of dream and reality through "abjection". Therefore, this study intends to analogize the conclusion through analysis of the animation focusing on the theory of Julia Kristeva. Abject appears as the phenomenon which cannot be disappeared and the one threatening to disunite which the subject had already organized in the symbolic. The self-feeling of characters is not stable and it keeps watch constantly on the one which may neutralize his caution. They are looking for the power to strengthen the life granting to the subjecthood by chora as the resisting power against the symbolic order. That is, the dreaming space where revengeful power of primitive libido is working and shows mother as Paprika as well as enters through DC mini, works as the semiotic chora as "maternal body". The healing of mental lack in the symbolic caused from here is connected on the borderland to divide between meaning and meaningless as well as normality and abnormality in the semiotic and this is the maternal power of the semiotic. Therefore, "abjection", "abject" and "chora" as well as care and healing of the other self appearing in the subjectivization process in the can be regarded as the one caused from the love towards the subject to be analyzed.

In the film Inception, we can see that the human dream world is depicted using Freud's psychoanalytical subconscious theory. Through the expression of the subconscious, And the ability to think and think deeply of human nature, such as presenting a new perspective to insight and expression. Based on Freud 's subconscious theory, this paper explores the expression of the dream world and the subconscious in the film and examines the meaning expression of the film through it. The main character is well described as living a chaotic life in obsession with obsessions and obsessions due to his subconscious uncontrollable through his dreams and dreams of being satisfied by the way the oppressed thoughts and desires are disguised I feel that I feel my foolishness and mood as a masturbation by dreaming and dreaming to turn back the moments of regret. In addition, conflicts and confrontations between consciousness and subconscious are expressed well in the form of confusion in reality and dreams. This application and application of humanities studies is a good example of the production of in-depth popular arts content, as we can see that it can add to the weight of depth setting, plot development, and above all creative time and space creation.

This study was conducted to analysis citizen's attitude and style to the foodwaste from l0th Sept. to 30th Sept. in 1996. The research was used questionare method and analysis was used prequency analysis and cross table method by SPSS (scientific statistics). The foodwaste of householdwaste account for 24.8%, and the magnitude by the kinds of garbage were waste from pre-cocking stage, fruitshell, foodwaste remained after eating, septic foodwaste during storage. The more the housewives'age are young, foodwaste volumne were much. Most remained foodwaste after eating were soup and pot stew. The main cause of foodwaste production was overvolumne cooking. 88.8% of answers think that a menu can be useful to reduce foodwaste. The survey showed that 87.3% of answers put into the meter-rate bag after removed wetness of garbage. 84.1% of answers thought that the recycling of foodwaste needed, but the practical housewife was only 21%. For the suitable treatment of foodwaste, Survey showed that the consistent policy of goverment and continuous publicity was needed essentially, and that the public notice of TV or radio was effective. All of answers would like to participate in recycling of foodwastes whether public-posting or personal-posting. To set up vessel of posting at household, the proper purchase price and space of institution are needed, also the solution of sanitory & aesthetic problem and the collection of composting-product must be achieved smoothly.
