  • Purpose: The purpose of this study is to provide reference points for the improvement work of churches' convenience facilities for the elderly. To do this, the study generates survey results, showing that the perception to significance of churches' convenience facilities is different among survey constituents. Method: The survey method was utilized. The study population for survey includes the aged believer over 65 years old, pastors, and architecture and/or interior design experts. The questionnaire was devised while consulting existing regulations regarding convenience facilities in general. Results: It is found that the perception to significance of installation standards for convenience facilities is different among survey constituents. Specifically, while the older believer group is perceived that installation standards for the small group meeting room of 'other facility' is comparatively more important, the pastor group and the expert group perceive that the 'intermediate facility' and 'inner facility' are more important. Implications: Participants involved in an improvement project of churches' convenience facilities may have a different perception about their importance due mainly to the degree of usage and the difference of perspectives. This study, therefore, can be used as a reference point for prioritizing improvement works of churches' convenience facilities for the elderly.

  • To manage national territory and cadastral data efficiently, accuracy and cost-efficiency in cadastral boundary surveying is inevitable. The efficient management of cadastral data is a very important element in national land management. Survey techniques are being introduced. Recently, improvements in survey techniques have been made with the development of satellite surveying, Allowing accurate and fast surveys. If we can calculate the output accurately in real-time in survey fields, it will open a new method in cadastral detail surveying. According to the classification on Law of cadastral surveying, Cadastral surveying can be divided into cadastral control point surveying and cadastral detail surveying. The control point survey can be divided into cadastral triangulation surveying and cadastral traverse surveying. The detailed survey is usually perform by plane surveying. Among these, cadastral detail surveying will be reviewed in this study. In this study, the combination of the satellites, such as US managed GPS and Russian managed GLONASS was used. In the satellite survey in downtown, data interruption symptoms arose(according to the mask angle of the satellite). Therefore; we combined the satellites to get date more accurately. A block of Haewoondae New City in Busan, Korea, which has Numerical Cadastral Law was selected as the sample area for this study. Block II and III are surrounded by high rise apartments. One side of Block I and IV is level ground and the other side is full of high rise apartments. Especially, Block II is surrounded by high rise apartment houses with 20 meters width. In the results of the study Block II did not satisfy the allowable precision, while Block I, II and IV satisfied the allowable precision of the enforcement regulations of Cadastral Law. Therefore, it is judged that the traditionally used Total Station method should be used for supplementary survey on Block II, in stead.
