Aged apartments lack parking space and are suffering from severe parking difficulties due to the increase in the supply of private cars due to the economic improvement. Efficient remodeling technology is required as a way to solve the problem of a shortage of parking spaces, but there is a lack of establishing a technology for remodeling plans that can reflect the characteristics of various parks. This study was conducted to analyze the functions of the parking lot expansion technology using the technology tree and to derive the final technology through the function deployment. As a result of functional deployment of the plan to expand the parking lot, the fifth function was deployed and a total of 22 technologies were derived. Four types of technologies are categorized, four technologies for underground expansion, 12 technologies for underground and ground expansion, two technologies for ground expansion, and four technologies for ground-based expansion. As a result of the functional deployment of the main entrance plan, the fifth function was deployed and derived with 22 technologies. The total technologies were grouped into four categories, four technologies for direct underground entry, 11 technologies for indirect underground entry, three technologies for direct access to ground, and four technologies for indirect entry to ground. Through case verification, the detailed technologies applied to the semi-industrial complex of remodeling were identified and expert surveys and interviews were conducted to verify the adequacy of the technology tree.

As public interests and demands on the library space and library goods increase, the role of librarians dealing with this issue has become more important. This research develops lists of core and non-core goods in space managements of public libraries, children's libraries, and school libraries. The lists will make the librarian's tasks effective and maximize user satisfaction. For public libraries, the space is divided into nine main areas, and a total of 80-90 goods(50-60 core and 20-30 non-core goods) are identified. The space of children's libraries is divided into four main areas(space for reading, books, entry, and special activities) with a list of 60-70 library goods(30 core and 30-40 non-core goods). School libraries consist of seven distinctive spaces, including spaces for books, multi-media, reading, and teaching, and it requires 90 goods in total(30-40 core and 50-60 non-core goods). The findings of this study can be utilized in listing up library goods. Further research should be conducted to develop such tools as guidelines, standards and manuals for space management.

The royal tombs of the Joseon Dynasty are divided into the entrance space of the inner and outer spirits in accordance with the characteristic of the ritual act. In each space, the ritual facilities are arranged and managed according to the characteristics of ritual acts and space. In the case of the Joseon royal tombs listed in the World Heritage List in 2009, further conservation and management of the original form is required, and the need to restore the original form is required. Especially, Yungneung and Geolleung requires landscape management in accordance with the World Heritage site management regulations, for example, management of horizontal 60 degrees view. This study aims to propose a prototype verification, preservation and restoration plan for the landscape around the core area of the damaged source. Through the verification of the old literature and field investigation, conservation and restoration plan is proposed for the landscape of the ridge, the water system, the scenery around the ridge line, and the historical scenery.

The number of households old over as much as 20 years is expected to get increased rapidly more than 1,000,000(1 million). As a measure to this fact remodeling is being revitalized over the country. parking lots expansion actually takes up a great deal of weight among the requirement for remodeling. When constructing a parking lot for enlargement, the way of going into the main building determines such construction features as selection of Retaining Wall Method, installation of an elevator, parking measure of capacity, etc. This study derived the affecting factors for selecting the way of going into the main building when constructing an underground parking lot. In a research way, we examined the features on each method of going into the main building in an apartment complex through an in-depth interview with some experts after investigating the method of enlarging an underground parking lot and going into the main building. After that, we derived the affecting factors for selecting the way of going into the main building. The affecting factors include constructability, convenience, economic efficiency as a high level as well as existence and nonexistence of basement and removal, safety of current building, parking measure of capacity, amenity, inhabitant traffic line, construction expenses and construction duration as a low one. This study will be applied as a reference for selecting the way of going into the main building when constructing an underground parking lot especially targetted on an old apartment house.

전통적으로, 토양은 식생의 분포를 결정짓는 중요한 변수로서, 생태 시스템의 보존과 관리를 위해서는 토양의 성질과 그 공간적 분포에 대한 이해가 선행되어야 한다고 알려져 왔다. 특히, 기질(substrate)이 사질 입자로 구성된 해안사구 생태 시스템은 영양소의 자체적인 생산이 충분하지 못하므로, 외부로부터 유입되는 영양소가 식생의 진입과 서식을 위한 필수적인 요소이다. (중략)

It is expected that the number of apartment complexes in Korea that are over 20 years old will rapidly increase to more than 3,500,000. Consequently, the remodeling of these buildings is being revitalized throughout the country. Among the requirements for such remodeling, the expansion of parking lots has considerable weight. When enlarging a parking lot, the access route from an underground floor to the main building (i.e., the means of entry into the main building) determines the possibility of vertical enlargement for elevators, the size of the parking lot, the construction period, and construction expenses, etc. When enlarging an underground parking lot of an apartment complex, the access between the main building and the parking lot, as well as the inhabitants' requirements for entering the main building, are generally determined based on the designer's experience, rather than on the exact estimation of the peculiarity of the complex. In order to resolve such a problem, when enlarging an underground parking lot, a systematic and rational method is needed for selecting the means of entry into the main building. In this study, a selection model is derived for the method of selecting an access route into the main building when constructing an underground parking lot, in order to provide a reasonable decision-making process. A research method was investigated for determining the access route into the main building when enlarging a parking lot. On the basis of research carried out through in-depth interviews with experts, the characteristics for each means of entry into the main building were analyzed and the factors affecting the selection of the access route were deduced. The affecting factors selected were construction efficiency, convenience efficiency and economic efficiency. Weight values were then estimated for the selected affecting factors by applying the AHP method. Results showed that convenience efficiency, which gained the highest value, is the most important factor in selecting the means of entry into the main building. The most suitable means of entry into the main building was also suggested after estimating the applicability of the site by selecting complexes with remodeling possibility. This study will be applied as a reference for selecting the means of entry into the main building when constructing an underground parking lot particularly for older apartment complexes.

This paper describes the real-time system which, through analyzing a sequence of images, can extract motional information on a moving object and can contol servo equipment to always locate the moving object at the center of an image frame. An image is a vast amount of two-dimensional signal, so it takes a lot of time to analyze the whole quantity of a given image. Especially, the time needed to load pixels from a memory to processor increase exponentially as the size of an image increases. To solve such a problem and track a moving object in real-time, this paper addresses how to selectively search the spatial and time domain. Based on the selective search of spatial and time domain, this paper suggests various types of techniques which are essential in implementing a real-time tracking system. That is, this paper describes how to detect an entrance of a moving object in the field of view of a camera and the direction of the entrance, how to determine the time interval of adjacent images, how to determine nonstationary areas formed by a moving object and calculated velocity and position information of a moving object based on the determined areas, how to control servo equipment to locate the moving object at the center of an image frame, and how to properly adjust time interval(${\Delta}$t) to track an object taking variable speed.
