The Unite d'Habitation at Marseilles was an experimental project that Le Corbusier had been waiting for since 1920s in order to explore his ideals and visions in mass housing and city planning. As a leader of the first generation members in CIAM, Le Corbusier tried to give a new form and an order to the Unite d'Habitation at Marseilles in both building design and city planning level. The purpose of this research is to investigate the design characteristics of the Unite d'Habitation at Marseilles in three different levels of built environment with a particular emphasis on the process through which an original form is derived from its contextual settings. In the level of city planning, Le Corbusier aimed to reshape traditional low-rise urban housing by deploying several Unites spaciously. Le Corbusier believed that the spacious deployment of Unites would bring us both the functional economy in the city and the natural amenity in the suburbs. As Unite d'Habitation would be called frequently as vertical garden city, the influence of suburban garden city on Unite d'Habitation is apparent. In the building level, the binomial harmony of individual-collectivity was pursued by providing three different public floors and by combining 23 different family unit types in the Unite d'Habitation at Marseilles. In order to visualize the concept of object-type, family units were prefabricated and inserted into the structural frame of the Unite d'Habitation at Marseilles. Two family units are combined to make a three-story section with street corridor in the middle. This three-story section unit is very original as it has access corridor every third floor and each unit could have considerable depth with the help of the living space of two story height. In consideration of formal and plan similarity as well as contextual edivdence, it is concluded that the three-story section of the Unite d'Habitation is derived more from Narkomfin Apartments than from the monastery at Ema or Immuble Villas.

The living lab is a user-participatory innovation space where users can solve problems by themselves. Living Lab members are able to participate in all aspects of product development from technology conception. In this study, to prevent pedestrian accidents, auto-image sensing signal system was developed in Jeonju City, using the Living Lab method. In addition, we measured effectiveness of the auto-image sensing signal system with respect to pedestrian waiting time, pedestrian and driver signal violation, and pedestrian jaywalking. It was also compared the measures before installation, after installation and after applying Living Lab method. As a result, all of the three measures of effectiveness appeared to be more effective after Living Lab than after installation. Overall, this study is very significant in that it is the first case where the living lab is applied in transportation.

The evacuation simulation study was performed with the boundary condition of a fire simulator, referring to Dae-gu Subway Fire Accident which was a real station fire. The subway station was modelled from B3F station building to B2F waiting room in fire simulation. Also, a fire simulation were performed with CFAST and FLUENT. In CFAST, the total 29 zones were divided into 18 station buildings in B3F and 11 station buildings in B2F. In FLUENT, the simulated space had the same establishment as zone of CFAST. The study focused on possibility for application of fire simulation in underground station by comparing the resulted values from two simulators. For application of fire effect, the fire data were loaded directly to EXODUS in the case of CFAST and performed a passenger evacuation simulation. In the case of FLUENT, Out Data values of a fire simulation were difficult to be compatible with EXODUS. Two resulted values of passenger evacuation simulation by fire simulation were compared with the Dae-gu Subway Fire Accident in reality.

Recently the countries breeding bears such as China and Vietnam are promoting a policy that gives relief to wild animals through agreement with AAF and WSPA. Currently our country has lacking breeding space for the increased number of bred bears due to the prohibition of bear import and export from joining the CITES in 1992. There needs to be a place that treats, protects accepts breed bears in the terms of animal welfare. The bear park was hoped to be designed as a means to give relief to bears and promote harmony with the local society, and is made of parking area, waiting area, visitors center, treatment research management facilities, restaurants, food warehouse, food store, bear museum, sanitation facilities, gondola, plaza, rehabilitation area for wild animals, outdoor exhibition center, direct indirect experience area of wild animals, resting facilities and areas, photo zones, bear playground, bear experiencing facilities, fences, information facilities, tree protection facilities and more. The design can be used as a reference in examining alternative measures following the future change in breeding policy as a bear park example which reflected the ecology of a bear in the term of animal welfare.

This study aims to develop a mainline metering strategy considering queue imbalance among lanes that can reduce congestion at a toll plaza section by managing queue caused by mainline metering. The suggested strategy considers simultaneously optimizing the number of cars in merging area and managing queue by lane. This study analyzes the effectiveness of the strategy with respect to the average travel time and the occurrence rate of spillback using the PARAMICS. The results show that the suggested strategy has an effect on reducing congestion and improving operation efficiency at toll plaza. In particular, the congestion become more intensified when the length of waiting space is shorter; however, this study shows that the suggested strategy can relieve the congestion in that condition.

In this study, to improve the quality of school lunch in local colleges, we conducted a survey on students who attend 2 year colleges in Jeju region. With its own unique regional characteristics and the change of its school lunch program from direct management to consignment, there were some questions about how each factor in school lunch program affects on students' satisfaction with it and we tried to present helpful data to improve school lunch programs in each region. The survey took place from May 5 to May 10, 2005 covering the colleges only in Jeju region. There were 200 sets of questionnaires issued and distributed to the students who are currently using school lunch programs. Only 168 sets were retrieved and processed statistically. 2 sets out of 168 questionnaires had to be thrown away because there were wrong entries of some questions, which made overall retrieving rate 83%. In this study, SPSS 10.0 , one of the statistical package programs, was used as an analyzing tool to make Frequency Analysis. To verify credibility, Cronbach's Alpha Element Analysis was done and T-test and ANOVA was also made. After Recurrence Analysis for elements of satisfaction regarding main factors that is considered to be important to customers, we found that importance of following factors: appearance of food, incongruity between main and side dishes, availability of seasonal food, availability of preferred menu, absence of food stock, waiting time, accessibility of food counters, space between chairs, presentation of a menu, food tray's shape, and color of food trays. The importance of those showed high but satisfaction with the same factors was low. So the primary improvement on these factors should be made to increase satisfaction. Finally we concluded that in large extent, importance of each factor definitely affects on students' satisfaction.

This study analyzed the working conditions of the fire protection system in the Goyang Bus Terminal fire based on the fire investigation results. The results were as follows. First, extinguishing using an indoor fire hydrant was not attempted immediately after the fire burned the ceiling urethane foam. Second, a sprinkler alarm valve was turn off and did not work in the repair work space of the 1st basement. On the other hand, the sprinklers in the $2^{nd}$ basement, $1^{st}$ floor, $2^{nd}$ floor, and $3^{rd}$ floor worked and prevented the fire from moving to stories other than the $1^{st}$ basement. Third, although an exit light worked normally, it was not installed in the exit from the waiting room in the $2^{nd}$ floor to the bus stop. This resulted in many casualties. Fourth, although a fire receiver sent an electrical signal to the fan controller of the smoke control system, it was treated manually in the fan controller and the fan in the $2^{nd}$ floor did not work.

This study focuses on a job-shop scheduling problem with the objective of minimizing total tardiness for the job orders that have different due dates and different process flows. We suggest the dispatching rule based scheduling algorithm to generate fast and efficient schedule. First, we show the delay schedule can be optimal for total tardiness measure in some cases. Based on this observation, we expand search space for selecting the job operation to explore the delay schedules. That means, not only all job operations waiting for process but also job operations not arrived at the machine yet are considered to be scheduled when a machine is available and it is need decision for the next operation to be processed. Assuming each job operation is assigned to the available machine, the expected total tardiness is estimated, and the job operation with the minimum expected total tardiness is selected to be processed in the machine. If this job is being processed in the other machine, then machine should wait until the job arrives at the machine. Simulation experiments are carried out to test the suggested algorithm and compare with the results of other well-known dispatching rules such as EDD, ATC and COVERT, etc. Results show that the proposed algorithm, MET, works better in terms of total tardiness of orders than existing rules without increasing the number of tardy jobs.
