In apartment type of housing, if resident's vehicle is registered in central control office and RFID TAG is issued, identification can be recognized from the time of entrance into parking lot and intelligent parking guide system can be activated based on the residents' profile. Parking Guide System leads a vehicle to the available parking space which is closest to the entrance gate of the vehicle's owner. And when residents forget where they parked their cars, they can query to the Parking Guide and Management System and get responses about the location. For the correct operation of this system, it is necessary to find out where the residents' cars have parked in real time and which lot is available for parking of other cars. RFID is very fancy solution for this system. RFID reader gathers the ID information in RFID TAGs in parked cars and updates the DB up to date. But, when non-residents' cars are parked inside apartment, RFID reader cannot identify them nor know the exact empty/occupied status of parking spaces because they don't react to RFID reader's query. So for the exact detection of empty/occupied status, we suggest the combined use of ultrasonic sensors and RFID. We designed a tree topology with intermediate data aggregators. The depth of tree is normally more than 3 from root (central office) to leaves (individual parking lots). The depth of 2 in tree topology brings about the bottleneck in communication and maintenance. We also designed the information fields used in RFID networks and Sensor Networks.

Recently, Korean people are more interested in leisure time as the Korean economy has enjoyed the economic growth on a continual basis. Along with it, the disabled people's demand for enjoying the beach is growing. To meet the disabled people's demand for enjoy the beaches, it is important to prepare the convenient facilities where the disabled people in the wheel chair can use comfortably, including the handicapped parking area, toilet for the disabled, shower stall room and am bathhouse. On the backdrop of this, the study has been made on the obstacles which keep the disabled people from using the convenient facilities installed on 12 beaches in the southern coat of Korea from the perspective of barrier free design. This study showed that half of the beaches in question did not have the handicapped parking places. The parking space was also so narrow that it was difficult for handicapped people to access the parking lot with their vehicles. There were also 3 beaches which did not have the toilet for the disabled. Even the beaches which have the toilet for the disabled, the size of entrance door and floor space was so narrow and there were a lot of physical obstacles such as no handles for the disabled people that it was really hard for the disabled people in wheelchair to use them.

Use of daylight in underground space interacts with physiological need for human beings and provides relief from feeling secluded. Light pipe system can deliver natural light into the space where it is needed and can be used as primary or a secondary light source with benefits of energy, productivity and health. To use light pipe system effectively under various conditions, it is important to investigate the effectiveness of light pipe system with reliable monitoring protocol. This paper presents the results of light pipe system performance used in underground parking lot under different sky conditions. Comparisons were made between the illuminance standards of underground parking lot and the monitored data. The results indicated that adequate illuminance level was shown until 4.5m distance from the light pipe under clear sky condition. However, additional lighting device showed be used under overcast sky to meet the proper illuminance level.

어둡고 한정된 지하공간의 이미지의 개선은 지하개발 성공여부에 중요한 결정요소가 되고 있다. 주거단지 지하주차장의 조명환경은 지금까지 양적 위주의 설계와 운영이 이루어졌으나 이제는 지하주차장 공간의 질적 향상이 필요한 때이다. 이를 위해서 우선 고려해야 할 두 가지는, 첫째로 주차장에서 주로 사용되는 광원에 대한 이해이며, 둘째는 균제도의 향상이다. 특히 겨울철 외기의 영향에 의한 주차장 실내의 심각한 조도저하와 균제도의 유지를 위한 방안이 마련되어야 한다. 따라서 조명기구의 간격, 배열에 대한 변화가 필요하며, 운용에 있어서는 시간에 따른 일률적인 기존의 제어방법에서 벗어나 이용패턴을 고려한 방식으로의 전환이 요구된다.

Korean urban traditional housing abandoned by the social apathy promptly disappearing form our sight, or ruining. It tells that the strategies we are using today are impossible to fulfill socio-economic needs of residents here. So it needed to find out the strategies which can change this place better to live in. Consolidating the street parking lots fer cars can be one of the important solutions to the area. By using cul-de-sac, after setting up small unit of communities, we will have chance to have a small public space, and at the same time it can help to set up our tradition of people's intimacy inside the community. Most people have their own cars, and the need of parking lots becomes more serious. So, a meeting place like public well in the past must replace parking lots. On the other hand, it is important to re-consolidate existing land to obtain appropriate land size for other uses. Today, the use of private space (house, private lots, etc..)and public space(streets, local offices) is very important. NIMBY (Not In My Back Yard) attitude should also be reconsidered. All these negative social aspects come from negative social relationship, thus we should consider them with care and deep understandings. The traditional housing of Korea should not be abandoned as slum, but this should be transformed in terms of the conservation since it is superior in its ecological and energy conservation aspect.

Traditional cars have a structure that steers the front wheels to change their direction so they have difficulties in performing parking motion, especially in a narrow space. As electric vehicles developed, robotics technology especially omni-directional mobile robot technology began to be incorporated into the automobile field. Omni-directional mobility and special turning movements are particularly useful for parking cars. In this paper, we propose a four-wheeled mobile robot. The proposed robot has a structure that can combine or separate robot body and robot wheel parts by using electric brakes. The proposed robot has omni-directional mobility and has the ability to rotate around an arbitrary point. Due to these omnidirectional and rotational characteristics, the proposed robot allows for various types of movements when applied to a car. In particular, parking is performed in a simple and intuitive manner that does not require complicated path planning. We implemented the proposed four-wheeled robot and showed its effectiveness by conducting several parking experiments.

The climate of urban area is an unstable type with considerable seasonal variation in precipitation wind speed, and temperature and it grows worse. Besides, ozone is a serious air pollutant in most of large cities. So worldwide, some of large cities are investing in forestry options to offset their climate problems, but lack of information has hindered comparisons of urban un cost effectiveness to other options. This research intends to study the economic benefits of tree shading of 19 parking lots in UCD campus. The economic benefits of tree shading are air conditioning savings, air quality, stormwater run-off, and other benefits. Especially, this study focuses how much the economic benefit of parking lot shading has been increased from 1995 to 2003 year by aerophoto. Some data on dimensions of parking lots and the number, size, tree species, and location of trees around each parking lot was inventoried. Two aerophotos(1995,2003) were used in order to analyze the increasement of tree canopy in 19 parking lots for 8 years. However, increasing coverage of trees and managing them for healthy growth would not be sufficient for avoiding adverse impacts by future climate change. Additional measures should be followed such as an increase of energy use efficiency and development of substitute energy. For example, coverage of trees help to save cooling energy by blocking solar radiation reaching parking cars and building structures through shading, and creating cool micro-climates through evapotranspiration. They also reduce heating demand by decreasing air infiltration and heat conduction out of the interior of buildings. Proper arrangement of vegetation over the parking lots can reduce cooling and heating costs. So proper planting design around hard space paving including species selection and location can significantly save cooling and heating energy. And a reduction in car and building's heating and cooling costs results in the reduction in energy demand which causes to emissions of air pollutants. Total increased tree canopy from 1995 to 2003 is $8,470.45m^2$ and the economic benefits is US$ 5,282.10. The economic benefit of one tree has been US$ 7.21 for 8 years. And an annually increased benefit is US$ 0.9 per a tree. If this kind of study is applied to studying the economic benefits of tree canopy in parking lots of Korea, it could result in guidelines of tree planting of parking lots. Because the trees selected for planting in parking lots were not suitable for an environment, the guidelines should contain a recommended list of trees. The guidelines should propose the shading percentage of parking lot when we plan a parking lot and contain the maintenance of trees in order to maximize the economic benefits of tree canopy.
