  • This study is concerned about the comparison of accuracy between the plane table survey and the transit survey in the boundary survey. Up to the present, the plane table survey is used for the boundary survey in Korea the plane table survey usually causes both human and mechanical observational errors large enough. In this study, both the plane table survey and the transit survey using total station were used and the same points were measured from the same station. As the results, the positional error has 2~20 cm in plan table survey and 0~2 cm in the transit survey. Thus the transit survey is considerably accurate compared to the plane table survey in the boundary survey.

  • Recently, Web-based Survey has attempted to overcome the limitations of Paper-based survey. This method is more effective in costs and time use than traditional methods, also help respondents to understand and interest in the survey. Especially for the elderly, web-based survey is effective survey tool, because audio-visual material could be provied. The purpose of this study is to evaluate the effectiveness of two kinds of methods which were web-based survey and paper-based survey, focused on elderly residents' needs for ubiquitous home service. The participants were older than 60 and divided into 2 groups, web-based survey and paper-based survey, each group was controlled over by age, gender, computer skill. For this study, elderly residents conducted a survey passed through 2 steps, the first was residents' needs for ubiquitous home services, the second was an evaluation of survey methods. Finding were as follows : first, there was no difference between the two groups in needs for ubiquitous home service, so survey itself can not make a difference in survey results. Second, respondents of web-based survey were more interested in and felt easier about method that they conducted than ones of paper-based survey. Finally, Web-based survey will be more effective method to be figure out the need of the elderly who are familiar with computer.

  • Despite of many supportive research to the usefulness of slide evaluation on environment of outdoor lighting, study method of using slides have provoked many discussions of its manifestation of reality of field conditions. This study aims to compare the results of slide survey with that of field survey. Distant view and short range view of nightscape of Seoul were selected. Field measurement of luminance and chromaticity were conducted and questionnaire survey were conducted. Frequency analysis, T-test, factor analysis were conducted. Results shows that distant view and short range view of field survey have better visual atmosphere than slide survey. In addition, slide survey on distant view shows lowest values. Difference between field survey and slide survey on distant view is much bigger than the results of short range view.

  • In case of executing surveys in marine ecosystems, the most important things are scientific selection measures of survey stations that can represent various ecosystems characteristics in subjected areas. The situations show a lot of differences that understand characteristics of marine ecosystems in targeted areas according to selection methods and positions in survey stations. Investigation ranges and station numbers in marine ecosystems are classified according to project characteristics and scales. But, currently a clear divisions or objective standards are not. Therefore, this study tried to provide selection measures of survey station in scientific and objective marine ecosystems through precise analysis among environmental impact statements of coastal development projects until now. In this study, impact scopes of marine ecosystems correspond to physical impact predictions by undertaking projects. Impact ranges were divided into three(physical impact ranges) coastal waters. In case of proposing numbers of survey stations according to this survey ranges, numbers of investigation stations due to minimum survey scopes in targeted projects applied 20~30% of all numbers in survey stations. Number of survey stations due to average investigation scopes within physical impact ranges applied 60~70% of all numbers in investigation stations. Numbers of survey stations due to maximum survey ranges within physical impact scopes applied 10~20% of all numbers in survey stations. So, improvement measures were deducted. Finally, according to prediction ranges in impact of various coastal development projects, several kinds of conclusions are suggested. And, it is thought to be able to use as fundamental database to select investigation stations in marine organisms through this study.

  • This study investigates methodological implications of cyberspace and information technology for online survey research Online survey method provides useful methodological tools for collecting empirical data for the study of cyberspace, In terms of sampling frame , selection method, and questionnaire from four major types of the online survey research can be found: member survey visitor survey e-mail survey and the electronic survey. Online survey research with sample design(population specification error. sampling frame error, selection error) measurement (measurement instrument bias system-related processing error, nonrespone, and response bias) and research ethics (privacy and netiquette) pose important methodological issues for the survey. The realization of the technological possibilities of online survey will be possible only through a right consideration of these issues.

  • There are direct and indirect approaches to measure the quality of rural life with comparison of urban. One of the direct approach is to survey living satisfaction of rural residents. Survey result is also important factor for the understanding of local needs in rural development. Rural Development Adminstration(RDA) has developed a survey table with 71 survey items for measuring the satisfaction of rural residents. In rural field forum which have conducted for finding the direction of rural development, the understanding of local needs with measuring the satisfaction of rural residents is important. But developed survey table is difficult to be applied in rural field forum not only many survey items but also overlapping in survey range. The purpose of this study is to suggest a field-applicable survey table in rural field forum based on results of RDA. Survey items were selected based on the importance score of RDA survey table, and weighting values were applied to each survey items. Finally, we suggested 31 items based on results with principle component and reliability analysis.

  • The objective of this study is to investigate actual conditions of terrestrial vegetation part in Environmental impact statement, and to prepare a proposal for the efficiency of Environmental Impact Assessment. 13 E.I.S.s made out during 1996.6-1997.5. have been chosen and analysed with respect to scope of survey, item of survey, method of survey, and result of survey. Actual conditioins of terrestrial vegetation part in E.I.S. are summarized as follows : 1. The mean number of total participants in drawing up E.I.S. is 26.0 persons, that of participants in terrestrial vegetation part is 2.3 persons. 2. In case of planar project, the mean of scope of survey is 16.1 times as large as area of project . In case of linear project, the scope of survey has been determined arbitrarily. 3. The most part of survey has been dependent on literature, and field survey has been practically neglected. 4. Results of survey mostly missed the point that E.I.A. pursues. And proposals are as follows : 1. Participants in terrestrial vegetation part in drawing up E.I.S should be increased. 2. It is necessary to subdivide scope of survey in view of difference between planar project and linear project. 3. As for item and method of survey, field survey should be specially reinforced. 4. Several sheets of map as results of survey should be included in E.I.S. The vegetation map, the D.G.N. map, and the planting map should be included and drawn by smaller scale as possible.

  • There is an increasing need to use mobile Internet as a research tool as wireless technology has been developing rapidly. However, little research has been conducted to confirm methodological validity of mobile Internet survey. This study examines the possibility of using mobile Internet as a survey tool by comparing survey results of mobile and stationary Internet surveys with the same questionnaire. The results were analyzed from both economic and theoretical perspectives. Both mobile and stationary Internet survey sites were implemented with supports from domestic mobile and stationary Internet portals and telecommunication companies. The results show that there exist several differences between two survey methods. First, many respondents who use mobile Internet gave up at the early stage. However, once people continued to respond, they answered the questions to the end. Second, means and standard deviations of mobile internet respondents were higher than that of stationary Internet. Third, the results of two survey methods were significantly different by comparing construct validity that includes both discriminant validity and convergent validity. Finally, this paper ends with implications and limitations of using mobile Internet as a survey tool.
