This paper selects two cities in Beijing, China and Seoul, South Korea as the research object. Based on the data of the Internet, this paper analyzes the guest house with high satisfaction of customers in the two regions. Through the investigation of the basic conditions of the guest house of two city ,we can compared the differences of the two city guest house. In order to achieve the advantages of reference, the deficiencies to be rectified. There are many similarities in the culture and geographical location between China and South Korea. As a combination of family homes and accommodation facilities, guest house has valuable research significance in interior design. However, the current number of related studies on guest house in the two countries is obviously insufficient. Most of China’s research focuses mainly on rural areas, while Korea’s related research focuses on marketing research. This survey refers to the themes related to Korean and Chinese guest house. The research on the previous two countries" guest house was organized and summarized. After a survey of the basic conditions, a simple analysis was performed on the interior design of the two city guest house.

In recent years, with the change of learning methods, the theory of informal learning has risen. The study of informal learning spaces has also become a topic of concern to scholars in various fields. This article mainly studies whether the internal space of Chinese university libraries as a representative informal learning space has regularity. Through literature review, comparative analysis and case studies, the development status and trends of informal learning and library space planning are discussed. Based on the theoretical investigation, a new library space composition benchmark based on the informal learning space theory is proposed. Through the space syntax, floor plans of 33 target Chinese university libraries were analyzed to determine the changes in the informal learning space of Chinese libraries. By analyzing the data, it can be seen that with the development of time, there are differences and correlations in the connectivity, total depth, integration, and choice of informal learning spaces in Chinese university libraries. This type of change is specifically explained in the conclusion section of the article.

Customers" online reviews have important business value in the age of big data. Especially in the accommodation industry, online review analysis has become one of the important data sources for researchers to understand customer behavior and investigate customer satisfaction. Based on 5715 online reviews of airbnb in Lijiang, China, Dec, 2020. This study analyzes the attractive factors of homestays in Lijiang, China, and explores consumers" views and attitudes towards Lijiang homestays. Through keyword analysis, hierarchical clustering analysis and Critical Incidents Technique, 15 attractive factors of Lijiang Airbnb were extracted from the corpus. The research results show that room and location are the most important attributes in consumer reviews, followed by environment and service. In addition, in the accommodation experience, the host as a service provider plays an important role in all aspects. These factors have an important impact on consumer satisfaction and booking propensity. Combined with the content of the comments, it explains how each factors affects the consumer"s living experience. This research expands the attributes that affect the airbnb consumer experience and provides marketing advice to homestay operators to help them better understand customer online review behavior and to help operators understand how to get a positive word-of-mouth evaluation in online reviews. Methodologically, this research has contributed to how to use and visualize big data in the P2P accommodation industry.

본 논문에서는 유비쿼터스 센서 네트워크 환경에서의 공간 영역 질의를 효과적으로 처리하는 공간 영역 집계 인덱스 기법을 제안한다. 새로운 정보화 패러다임인 네트워킹과 컨버전스 기반의 유비쿼터스 환경의 중요성이 부각되면서 유비쿼터스 센서 네트워크 환경에서의 에너지 효율적인 실시간 공간질의에 대한 연구가 활발히 진행되고 있다. 센서 네트워크에서 공간영역질의는 사용자가 지정한 일정한 시간 동안의 특정 지리적 영역의 온도, 습도 등 스칼라 데이터를 감지한다. 공간 질의를 효과적으로 수행하기 위하여 Rectangle 기반의 SPIX기법 등 공간 인덱스 기법들이 많이 진행되었지만 기존 연구에서는 공간 영역질의의 질의 결과 값 전달 경로를 질의 전달 경로의 역방향으로 지정하였다. 센서 네크워크의 공간 영역 질의에서 질의 영역 내의 센서들은 대부분이 인접되어 있지만 질의 전달 경로가 틀리면 질의 영역 내에서 집계되지 못하고 전달되므로 불필요한 에너지를 낭비하게 된다. 본 논문에서는 유비쿼터스 센서 네트워크에서 공간 영역 질의를 수행 할 때 질의 영역 내에서 센서 노드들 간의 통신거리를 고려하여 질의 결과 값 전달 경로를 재선정하고, 적응적으로 집계 영역 내에서 집계연산을 하여 질의 결과 값을 전달하는 인덱스 기법을 제안한다. 성능평가를 통하여 제안 기법이 기존 기법보다 우월함을 보여주었다. In this paper, an adaptive range aggregation spatial index method is proposed for spatial range query in ubiquitous sensor networks. As the ubiquitous sensor networks are the new information-oriented paradigm, many energy efficient spatial range query methods in ubiquitous sensor networks environment are studied vigorously. In sensor networks, users can monitor environment scalar data such as temperature and humidity during user defined time and spatial ranges. In order to execute spatial range query efficiently, rectangle based index methods are proposed, such as SPIX. But they define the return path as the opposite of its query transmit path. However, the sensor nodes in queried ranges are closed to each other, they can't aggregate the sensed value in a queried range because their query transmission paths are different. As a result, the previous methods waste energy unnecessarily to aggregate sensing data out of the queried range. In this paper, an adaptive aggregation index method is proposed that can aggregate values in a user defined range adaptively by using its neighbor information. It is shown that sensor power is saved efficiently by using the proposed method over the performance evaluation.
