In Korea, the apartment buildings have been constructed recently in large quantities to provide housing due to the gravitation of population towards large cities. However, because of this trend toward high-rise apartment, a number of problems are occurred such as the deterioration of comfort in the dwelling environment and the lack of solar access right in apartment buildings. In the building law, the sunshine hour and the minimal separated distance between apartment buildings as regulated as the criteria for the site planning. Most of site planners, however, designed the apartment site only following minimum separated distance. As a result, the problem of sunshine hours lack is caused and legal dispute concerning solar access right is also arisen. The purpose of this study is to improve solar access right regulation and to help site design of apartment planning. Accordingly, we execute empirical analysis based on computer simulation in order to find suitable separated distance between typically designed apartment buildings. First, we estimated sunshine hours according to independent building orientation, height, and length. Second, we calculated sunshine hours in various case of apartment arrangement; parallel type, courtyard type, tower type and etc. with various separated distance.

In this study, an examination and an analysis are carried out on the forms and components of the access spaces of hotel entrances from the front gate of five star hotels in Jejudo, Korea. The results of the study are as follows. In terms of the arrangement of the hotel, city hotels with a relatively narrow site area are influenced by site shape, while resort hotels with a relatively wide site area are affected by the environment. However, the location of the front gate was determined by the access road from the outside. Therefore, forms of access space are related to the front gate, which is governed by the access road, and to the entrance, which is determined by the hotel arrangement. If the front gate is in line with the hotel entrance, a straight line and the hotel are arranged vertically to the front gate(side arrangement) or the hotel is arranged horizontally to the front gate, but if the entrance is not in line with the front gate, it appears as a curved shape. However, those who use their own cars have a variety of choices for access route depending on the location of the parking lot.

Visitors to a Web site leave access logs documenting their activity in the site. These access logs provide a valuable source of information about the visitors' access patterns in the Web site. In addition to the pages that the user visited, it is generally possible to discover the geographical locations of the visitors. Web servers also records other information such as the entry into the site, the URL, the used operating system and the browser, etc. There are several Web mining techniques to extract useful information from such information and visualization of a Web log is one of those techniques. This paper presents a technique as well as a case a study of visualizing a Web log.

Ethernet Passive Optical Networks (EPON) are an emerging access network technology that provide a low-cost method of deploying optical access lines between a central office (CO) and a customer site. This paper shows that subscriber unit manages traffic data between a central office (CO) and a customer site in economic solution.

Transradial access is a widely accepted method for percutaneous coronary diagnostic and interventional procedures, and it has dramatically reduced access site vascular complications compared to transfemoral access. Arteriovenous fistula formation at the access site is an especially rare complication in transradial access. We report an extremely rare case of delayed radial arteriovenous fistula that developed one year after transradial coronary angiography, which was successfully treated by surgical repair.

Along with the changing pattern that the construction project is getting complicated, large-scaled and up-to-dated, necessity of efficient management of manpower and resources of the construction site is being increased. In particular, considering that the construction site requires a lot of labor force and in terms of the construction cost, labor cost shares 30-40%, labor management has become a very important factor. In this study, in order to support a stable and successful construction project implementation and supplement the existing system being utilized at the current site, construction site access management automation system based on hand vascular pattern, a biometrics system, is intended to be developed. Relevant theory for the system development and the problem of existing RFID system were evaluated and based on this findings, a system design and DB composition chart were envisaged. In addition, by applying this developed system to a number of sites, its result was analyzed

The term 'Grid' refers to systems and applications that integrate and manage resources and services distributed across multiple control domains. Resource sharing is, necessarily, highly controlled, with resource providers and consumers defining clearly and carefully just what is shared, who is allowed to share, and the conditions under which sharing occurs. In this paper, we design and implement a grid access control system, called PGAM. This system works on heterogeneous resources, can be applied to the additional service development and its service, provides template account management mechanism, and tries to ensure site autonomy. This system is implemented to increase portability and to be tit tll any kind of economic model.

As the construction site becomes larger, more complex and more special, the information of construction is expanded in quantity and specialized in quality. Therefore the computing system is necessary to effectively manage the construction schedule management. At present, main office at construction site bring in the computing system to perform the schedule management, so the data input and access for schedule management is performed by engineer on foot between construction site and main office. Therefore in this paper, we arrange wireless communication system between construction site and main of office and develop application program for data input and access of schedule management immediately using PDA at construction site. Through the our system we can improve the schedule management at construction site, and we can look forward to reduction of manpower, equipments, time, and money in whole construction.

This study was conducted to establish a management plan for the Sangrim Woodlands restoration by analyzing the vegetation survey and the site characteristics of the Sangrim Woodlands Natural Monument (Natural Monument 154) in Hamyang-Gun, Gyoungsangnam-Do, Korea. According to the vegetation analysis, the species diversity by the location of Sangrim was higher near forest (1.000) than near urban (0.358) areas. Although forest occupied 53% of the Sangrim woodlands area, it is still insufficient, requiring to transform arable land, lawn, or house areas to the forest within the woodlands. Soil bulk density was increased in access areas frequently used by public, while it was decreased in closed areas. Soil hardness at 0-10 cm soil depth was generally improved in the closed areas, while became worse in the public access areas compared with the soil hardness in 2004.

Currently, many people have been researching diverse mechansmims related to a resource access control in Grid environment. Mostly Grid user's resource access control was designed to authorize according to their attributes and roles. But, to provide Grid with resources continuously, a resource access based on utility computing must be controlled. So, in this paper we propose and implement mechanism that intergrates Grid accounting concept with resource access control. This mechanism calcuates costs of Grid service on the basis of accounting, and determines based on user's fund availibility whether they continue to make use of site resources or not. Grid jobs will be controlled according to a site resource access control policy only if the amount of available fund is less than its costs. If Grid job completed, resource consumer pays for the costs generated by using provider's idle resources. Therefore, this paper provides mechansim to be able to control user's resource access by Grid accounting, so that it is evaluated as the research to realize utility computing environment corresponding to economic principle.
