The digitalization of our society has brought on the digitalization of housing design and human life. Thus, the concerns for developing digital home have increased. However, most of them has focused on digital technology, not human. This study was intended to examine the residents' housing needs for digital home and to suggest the design guidelines of digital home. The subjects were 400 housewives who lived and used internet in $85m^2$-sized housing unit in the new apartment complex, Busan. The important aspects in digital home design, the residents' needs for digital home design, and the needs for digital system in digital home were examined. The subjects were relatively young in their ages. Also, they had relatively high educational level and middle income. On the base of their housing needs for digital home, the design of digital home like as followings would be desirable: 1) the safe and secure design and digital system, 2) the design to improve residents' health and encourge family interaction, 3) human, warm, and soft interior mood, 4) space composition different from the existing one.

Re-auction happens when a bid winner defaults on the payment without making second in-line purchase declaration even after determining sales permission. This is a process of selling under the court's authority. Re-auctioning contract price of real estate is largely influenced by the real estate business, real estate value, and the number of bidders. This paper is designed to establish a statistical model that deals with the number of bidders participating especially in apartment re-auctioning. For these, diverse factors are taken into consideration, including ratio of minimum sales value from the point of selling to re-auctioning, number of bidders at the time of selling, investment value of the real estate, and so forth. As an attempt to consider ambiguous and vague factors, this paper presents a comparatively vague concept of real estate and bidders as trapezoid fuzzy number. Two different methods based on the least squares estimation are applied to fuzzy regression model in this paper. The first method is the estimating method applying substitution after obtaining the estimators of regression coefficients, and the other method is to estimate directly from the estimating procedure without substitution. These methods are provided in application for re-auction data, and appropriate performance measure is also provided to compare the accuracies.

With the fast growing number of skyscrapers and large ultrahigh apartment complexes, the concerns on fire caused by electricity also grow. Among about 30,000 fires recorded annually, roughly one third of them are hewn to be caused by electricity. If one of such high and densely populated buildings or apartments catches a fire, the consequence can potentially be quite catastrophic. However, with the rapid development of the techniques in the fields of communications and computers, electric power distribution systems for such buildings and apartments have been largely digitalized in recent years. More detailed informations on the operating status are now available, which enables more sophisticated monitoring and early detection of potential fire caused by electricity. In this paper, we present an inference technique that can be used as one of the basic techniques in building intelligent distribution panel systems that can effectively monitor, prevent and detect the occurrence of fire caused by electricity. The technique can accommodate production rules in linguistic expressions on high abstraction levels. Fire finding strategies can be easily modified to provide more effective countermeasures. Simulation results show that inference capabilities and thus the capability of fire monitoring in power distribution panel systems can be significantly enhanced with our approach.

본 논문은 전력회사와 수용가가 실시간으로 상호 협력하면서 효율적으로 여름철 냉방부하를 관리하여 첨두부하를 저감하기 위한 기법에 대하여 기술한다. 전력회사가 필요 관리량을 수용가 측에 요청하면 부하관리 요청을 받은 수용가, 예를 들면 대규모 아파트 단지의 중앙 지능관리 서버(Central Intelligent Management Server: CIMS)가 자율적인 관리를 통하여 요구받은 관리전력 이내로 부하율을 조정하도록 한다. 부하율을 관리하기 위한 수단으로CIMS는 필요 관리 부하전력에 따라 냉방기를 가동할 수 있는 권리에 해당하는 적정 수의 토큰(Token)을 발행하고 각 세대내의 냉방기를 제어할 수 있는 다수의 로컬 지능관리 서버(Local Intelligent Management Server: LIMS)들이 각 집안의 상황에 따라 냉방기를 가동하기 원할 경우에 전체 관리 서버에게 냉방기를 가동할 수 있는 권리에 해당하는 토큰을 요청하도록 한다. CIMS는 LIMS들의 토큰 요청을 관리하기 위한 큐(Queue)를 구성하여 관리하고 토큰을 요구한 각 LIMS들은 토큰을 할당받는 대로 자신이 담당하는 세대내의 냉방기를 가동하고 일정조건이 만족되면 자율 또는 타율로 토큰을 반납하여 큐에서 기다리는 다른 LIMS들에게도 토큰이 할당될 수 있도록 한다. 큐 운영 정책에 다양한 냉방기 운용 환경 정보를 반영하고 CIMS와 LIMS간에 원만한 상호 협력을 위하여 지능형 멀티 에이전트(Multi-Agent) 시스템으로 구성하고 이들을 계층구조의 네트워크로 연결하였다. 제안하는 기법을 서울의 한 아파트단지의 여름철 전력수요 데이터를 예로 하여 예상되는 대기 시간과 지원 받을 수 있는 전력요금 규모를 산정해 보았으며, 비교적 적은 수용가의 불편으로 큰 부하관리 효과를 얻을 수 있는 것을 알 수 있었다.

This study conducted a visual impact assessment of an apartment complex project proposed in Jungkye-dong, Seoul. Three design alternatives of the project-alternatives 1, 2, and 3-which differed in form, color, scale, and arrangement of buildings were simulated with computer image processing technique. The simulations were presented to the public who were mainly residents in the project area, and visual impact resulted from the alternatives was assessed by them. Their responses were then statistically analyzed. It was found that, in terms of compatibility with the surrounding landscape, alternative 1 was the most favourable because it was more traditional, natural, and diverse than alternatives 2 and 3. At the same time, the alternative was most preferred by the public because it was more plain, natural, and diverse than other alternatives. It was suggested that the visual impact assessment with public participation conducted in this study would help both planners and the public to make more intelligent decisions.

최근 건설업체는 주택상품 기획시 홈네트워크를 차별화 요소로 사용하고 있으나 공급자로서의 역할만 하고 있을 뿐 앞으로 창출될 거대한 규모의 홈네트워크 시장에 대한 적절한 수익모델을 발견하지 못하고 있는 실정이다. 관련업계에서는 유비쿼터스(Ubiquitous)시대를 대비하여 국가성장동력으로 삼으려는 정부의 정책하에 관련 가전, 통신, 방송업계의 시장선점을 위한 각축이 진행중이다 한편 인구구조 및 라이프스타일의 변화 등으로 인해 디지털화된 주거환경에 대한 소비자의 요구도 높아지고 있다 그러나 현재 거주자들에게 제공되고 있는 대부분의 홈디지털 서비스는 정책적 뒷받침의 부족과 분양가상승 우려 등으로 초보적인 수준에 머물러 있는 것으로 조사되었다. 미래주거환경을 선도해야할 건설사들에게 고객특성별 수요분석을 통한 품목 개발과 적극적인 수용의지가 요구되고 있다.

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.

In this paper, a self-propulsive and small concrete floor finishing trowel robot with twin trowels is proposed. Due to the small size and omni-directional moving capability, it is adequate for small space such as apartment. By adjusting the posture of trowels, it can move in any direction without wheels. We used cheap PIC processor for the cost saving design of the modules and adopted mode processors for easy operation of control stick. For the position control of the robot, we made a motion control algorithm appealing to the stepping motor driver module and the wireless communication module between the robot and PC (or control stick). In this paper, we discuss the control problem of the floor finishing robot in order to move to the right position. By comparing experimental result with simulation, we show the validity of the robot mechanism, sensors, and the control system.

Since 2000, there have been many changes in the residential types, such as an intelligent apartment which integrates both resting space and production space with comfort able, pleasant and safe environments based on internet systems. As the result of the rapid decrease in the birth rate and the prolonged lifespan around the world, it is expected that we will enter into an aging society by 2026. With such the expected change in the living patterns, many issues concerning the increased number of the elderly people have emerged as major social problems such as changes of family formation, its function and values, responsibility of caring for the aged, health and medical care, habitation policies and so on, and it is required to reconsider the social awareness on the living qualities of each old person. However, we have not yet satisfied such requirements with appropriate policies for the improvement of the living environment for them. It is considered, therefore, that we need to develop a new tool that, according to our goals, can give us a broad understanding on several considerations in designing the future homes for the elder people, making it possible to check the process changed by residents' needs in real time and apply it immediately to the space. As we have seen, it is required that spatial design process and design methodology should be considered in designing the homes for the aged for the pre-occupancy design evaluation.
