위치기반서비스(LBS)는 사용자의 위치를 기반으로 다양한 정보제공 서비스를 하고 있다. 최근 연구에서는 단순한 정보제공이 아닌 사용자의 상황인식(Context-Aware)을 통하여 사용자에게 적합한 정보를 제공해주는 지능화된 서비스를 제공하고 있다. 하지만 현재 연구들은 사용자의 기본정보와 선호도정보를 이용한 단일기준 추론을 통하여 사용자에게 정보를 제공해주고 있으며, 이것은 사용자의 다양한 기준의 의사결정을 반영하지 못하는 한계점이 있다. 이러한 한계점을 극복하기 위하여 본 연구에서는 사용자의 정보, 선호도, 공간지리선호도 정보 Ontology를 구축하고, 의사 결정 기준에 가중치를 부여하는 Cost Value Ontology를 구축하여, 다 기준 의사추론을 통해 사용자에게 적절한 추천 결과가 도출되는 Ontology 추론시스템을 제안한다. 사용자들의 개인적인 특성 지식과 공간지리 선호도 지식을 구축할 수 있으며, 이러한 특성으로 구축된 지식 기반 하에 입력된 사용자 정보와 추론을 통하여 이 시스템을 통해 사용자의 선호도 Ontology를 구축할 수 있으며 이를 이용한 추론을 통하여 사용자의 현재상황에 적합한 결과를 도출함을 보였다.

This study analyzes the key factors of 3D spatial information in accordance with the establishment of aerial and ground equipment fusion, and the quality improvement solutions are delivered from the preference survey. Furthermore, it investigates the factors affecting the quality of the individual technical elements through the establishment of three-dimensional spatial information. It is for identifying the priority which needs to be improved, and this data will be used to identify the evaluation for factors, the technology development and its application. For this purpose, the presence or absence of equality is judged by the quantitative techniques through the preference survey of the gap between the experts of spatial information and survey and the general users who have experiences on 3D spatial information.

We analyzed pedestrian preference and features of preferential space by MDS (Multi Dimensional Scaling). As the result, features of pedestrian space in dimension 1 could be interpreted as "Segregation of Pedestrian and Vehicle", and features of pedestrian space in dimension 2 could be read like "Natural-City". And as a result of vector analysis about preferential of pedestrian, a pedestrian mall between housing complex, pedestrian space in pocket park, pedestrian space in neighborhood park, and pedestrian space around public facilities was the best preferential space. On the other hand, pedestrians tended to dislike pedestrian space between detached.

This study was to research the effective use of green rooftop space, facilities and gardening, targeting members from community rehabilitation centers with disabilities. The three community rehabilitation centers studied were, Namyangju Center located in a rural area, Seoul Center located in a urban area and Siheung Center located in both a rural and urban area. We analyzed the difference in preference on the basis of each local community area. In fact, it indicated that 50% of each center knew about the green rooftop at their facilities and its use as a place for taking walks and conversation. It also showed that there was the high preference for priority objects such as a bench, pergola and trash can. Also the preference for natural visualizations like herbal or ornamental plants. The study showed a high preference to a small vegetable plot, hands on gardening and ecological wetland. It also indicated that there was a high preference for experience in nature programs on the rooftops (28.9 %) versus the rate of horticultural programs (27%). Therefore, it proves that the composition of a green rooftop at a community rehabilitation center should be differentiated so that the green rooftop can be a place not only for resting, but also great for a natural learning experience and gardening therapy for people with disabilities.

Libraries have recently sought to diversify their roles to meet the changing needs of local residents, while faithfully playing the library's original roles. The creation of a complex cultural space and the provision of services based on it are one of the ways to expand its role. In this study, a surveyed and analyzed the awareness of the complex cultural space of the library and the preference and awareness of the program operated in the complex cultural space by conducting a survey on the users of the library currently operating the complex cultural space. As a result, first, it was found that they preferred information space, education space, and rest space in space preference. On the other hand, community space and experience space showed low preference. Second, they prefer educational programs, exhibition programs, and performance programs that utilize complex cultural spaces, but experience programs and community programs have low preference. Therefore, it is necessary to operate the program by providing exhibitions and performance spaces while providing information and education spaces to users. The librarian should also promote the fact that library can be only the space of information and education, but also the space where culture, healing, experience and communication take place. In addition, libraries should strive to improve user awareness of library space.

To quantitatively measure or evaluate aesthetic factors is not easy in comparison with physical, functional, behavioral or economic factors. Yet aesthetic factors essentially play an important role in design modeling process. Despite its importance, research on aesthetic assessment or the interaction of aesthetic influential elements is insufficient. Therefore, this study is intended to find the relationships between visual preference and aesthetic variables of perceptual-cognitive dimension and affective dimension in commercial space design. According to the result of this substantiation research, aesthetic variables that give a positive effect on the preference of commercial space design are unity, order, and clarity in perceptual-cognitive dimension and 'pleasant', 'relaxing' in affective dimension. On the other side, aesthetic variables that give a negative effect on the preference are contrast, complexity, and ambiguity that is a contrary concept of clarity in perceptual-cognitive dimension and 'exciting', 'arousing' in affective dimension.

본 논문에서는 협력적 여과방식에서 고객의 특정 상품에 대한 선호도 예측의 정확도를 향상하기 위해 상품의 선호도 값에 가중치를 반영하는 전처리 방법을 제안한다. 이를 위해 고객별 상품의 선호도 값에 정보검색 분야에서 사용되고 있는 벡터 공간 모델을 이용하여 가중치를 부여하며, 이를 통하여 특정 상품을 선호하는 고객과 전체 상품을 고루 선호하는 고객간의 차별화 값을 반영하여 보다 정확한 선호도를 예측할 수 있게 된다. 전처리 과정을 수행하지 않은 기존의 협력적 여과 방식과의 실험을 통한 비교 분석을 통하여 본 논문이 제안하는 전처리 과정의 타당성과 비교우위를 검증한다.

복합 스케줄링 작업은 탐색 공간이 방대하므로 단순 스케줄링을 통한 방법으로는 최적해를 찾는 것은 쉽지 않다. 복합 스케줄링 문제를 해결하는 기법들 중에서 사용자의 선호도를 고려한 기법은 제약만족문제와 객체지향개념을 스케줄링에 적용하여 복합 스케줄링 문제를 해결하고자 하였다. 본 논문은 사용자의 선호도를 고려한 기법을 예약 문제에 적용하여 예약 시에 일어날 수 있는 문제점들을 해결하고자 하였다. 특히 고객들의 만족도를 높이기 위해서 고객들의 선호도를 고려하여 스케줄링을 한다. 고객의 선호도를 고려한 예약 스케줄링 기법은 객체 지향 개념을 기반으로 하여 각 객체들이 사건들을 가지고서, 이 사건들을 주어진 제약들에 만족하도록 보드에 배정하는 기법이다. 각 객체들은 전체적인 만족도를 고려하면서 그 객체들의 우선순위에 따라서 자원을 배정하고, 자원에 대한 객체의 선호도 차이를 가질 수 있게 하였다. 예약 스케줄링을 할 때 제약은 전역제약과 지역제약으로 구성된다. 보드에 대한 정의와 모든 사건들에 대한 정보를 전역제약으로 사용하고, 각 객체가 가지는 보드의 슬롯들에 대한 선호도를 지역 제약으로 사용한다. 사건의 배정을 실패하지 않고 백크래킹을 최소화하도록 앞을 보는(look-ahead) 백트래킹 기법을 사용하여 전체 객체들의 만족도를 높였다.
