  • As rural landscape is considered important elements of rurality, there are many concerns about management and conservation. Rural development administration have performed rural amenity resources survey project in South Korea from 2005 for verifying states and efficient management of rural amenity. There are some problems about ambiguous definition of rural landscape range and data overlap. In this research, we reviewed rural amenity resources survey focusing rural landscape and analysized elements of 50 complex landscape resources in 2008 rural amenity selection 100. Finally, we suggested landscape viewpoint resource table in place of rural landscape because it can minimize data overlap in survey project.

  • A gravity survey is a base of research earth gravity field determined, perception of the vertical motion, change of Geoid, sea-level changes, climate change etc. Recently, FG-5 was adopted in NGII. NGII has completed 4 points of absolute gravity survey and 1,400 points of relative gravity survey in 2009 to aim to observe 20 points of absolute gravity survey and 6,000 points of gravity control point by 2013. Using results of gravity survey, NGII will provide citizen with data for research about renewal of geoid model and geophysics. This study aims to go over examples of utilization of absolute gravimeter & method of utilization in korea.

  • Questionnaire survey on performance requirement of ship’s speed such as not only accuracy but also response and robustness were carried out, and the experiments to survey the GPS performances of static and dynamic characteristics were carried out simultaneously. In this paper, the questionnaire survey focusing on docking maneuvering, some analytic results of the survey, the results of GPS performance, and the possibility of adaptation for docking maneuvering on SDME and GPS are discussed. Consequently, from the results of questionnaire survey the performance requirement of ship’s speed in docking/anchoring maneuvering have need under 1cm/sec on the standard deviation, and speed information from GPS was adopted to use maneuvering information in docking/anchoring.

  • Work platform is temporary material that many workers use in construction field, but many workers construct and use the work platform without considering safety standards, workers who have not the knowledge of safety standards construct the work platform in weakness and use the work platform in unstable, According to the statistics in 2009, 1230 people were injured at the work platform. Among them, victims by falling account for about 77% and mostly lead to fatal injuries. we have studied and survey about the safety or danger of the work platform(set limits to duble scaffold) in construction field and about how many workers observe safety standards of the work platform. According to the result of this survey, 24%~100%(average : 68%) of the work platform in survey is not observe the safety standards.

  • This study aims to analyze the usefulness of the survey procedures developed for telephone surveys using a random sampling method. We conducted a telephone survey of residents in a local area from October 26 to November18,2009. We applied random sampling procedures with five call-backs. Particular attention was given to the conversion of refusals. Out of 2,454 phone numbers, we succeeded in getting responses from 637 numbers. The absence of residents was the primary cause of non-response. We received responses from 45.7% of those with whom we successfully made contact. One finding of this study is that, contrary to our initial expectations, call-backs do not significantly increase the percentage of responses from young people. Also we cannot find any significant differences in responses to various questions between the responses received from the first round of calls and later responses. However, these results are not conclusive; another survey may produce different results. Therefore, further research is needed.

  • The purpose of this study is to evaluate the opinion survey data quality used in theses and to suggest the data quality evaluation model. We used 16 items which were suggested by KASR(Korean Association for Survey Research) as a standard of survey data quality evaluation in thesis. According to the result, the data quality used in the theses is very poor level not to be accepted. And we tried difference tests between two proportions in order to find there were significant differences among stochastical variables. The result showed that there were some significant differences in sampling error and number of analyzing method between doctor and master. we suggested a model that was weighted by 9 special items for a survey data quality evaluation in a thesis by observing them from KASR's principles.

  • This study is an attempt to explore the perceptions of the public on women in higher education and employment, using data from the World Value Survey, had 90,350 respondents, of which 48.03% are male (N=43,391) and 51.87% are female (N=46,878). This study indicated that women, younger people, upper class people, religious people, and married people are more likely to have strong views against women's education and employment.

  • In business survey. cut off sampling is usual. The contribution from cut off part of the population is at least small in comparison with the remaining population. In this study. the population have been separated as three stratum, cut-off. take-some, take-all, and we will estimate cut-off part.

  • 지난 4월 13일 실시된 16대 총선에서 방송사와 조사기관들이 공동으로 조사하여 발표한 선거예측조사에서 많은 오류가 발생하고 이로 인해 표본조사에 대한 신뢰성에 큰 문제가 제기되었다. 이에 향후 선거계측조사의 신뢰성을 회복하고 보다 정확한 예측을 위해 기 발표된 예측 조사내용을 다각도로 심층분석하고 조사의 오류가 발생한 원인과 이를 해결하는 방안을 제시하였다. 아울러 이번에 처음으로 실시된 출구조사에 대한 문제점과 개선 방안도 함께 살펴보았다.
