The Korean Academic Multimode Open Survey (KAMOS) is a national survey first conducted in 2016. Stratified cluster random sampling was used in an initial face-to-face survey during which panel members were recruited. The second survey allowed invited panel members to answer online or by phone. KAMOS includes both longitudinal items and omnibus items, i.e., researchers can propose questions to include on KAMOS. This paper seeks to establish that KAMOS is representative of the South Korean adult population. The demographic variables from the first survey were comparable to demographic variables from two well-respected surveys in South Korea: the KOSTAT Social Survey and the Gallup Korea Omnibus Survey. To ensure that there was no substantial difference between those who answered the first survey and those who answered the second survey, we compared the results of 22 items from the first survey. The 2,000 panel members who were invited to participate in the second survey had similar responses to the 1,008 of those who responded to the second survey. Based on our findings, KAMOS can be considered a representative sample.

Traditional Korean Medicine Information Portal OASIS has been upgraded continuously from the beginning of it's service. It builds up more contents and adds more functions to provide rich information for TKM's researcher. But it's improvement strategy is not systematic and not supported from objective data. So we did online survey and analyzed the results to get insight for improving and activating the OASIS. Also we compared the survey with the previous one conducted in 2009. From the analysis of survey, we can get the 4 results. First OASIS have aged users than young users. Second 39.0% users are using OASIS 2-3 times in a month. Third 18.8% users want OASIS to provide the conference paper in TKM. Finally 21.7% users want paper map analysis system. We must do information strategy planning to get the insight for the improvement. And this survey analysis result will be most important material to our planning. Also we will use this survey analysis result to satisfy the users' needs.

This paper considers whether random sampling always produces more accurate survey results in the case of South Korea. We compare information from the 2010 census to the demographic variables of three public opinion surveys from South Korea: Gallup Korea's Omnibus Survey (Survey A) is conducted every two months by Gallup Korea; the annual Social Survey (Survey B) is conducted by Statistics Korea (KOSTAT); the Korean General Social Survey (KGSS or Survey C) is conducted annually by the Survey Research Center (SRC) at Sungkyunkwan University (SKKU). Survey A uses quota sampling after randomly selecting the neighborhood and initial addresses; Survey B uses random sampling, but allows replacements in some situations; Survey C uses simple random sampling. Data from more than one year was used for each survey. Our analysis suggests that Survey B is the most representative in most respects, and, in some respects, Survey A may be more representative than Survey C. Data from Survey C was the least stable in terms of representativeness by geographical area and age. Single-person households were underrepresented in both Surveys A and C, but the problem was more severe in Survey A. Four-person households and married persons were both over-represented in Survey A. Less educated people were under-represented in both Survey A and Survey C. There were differences in income level between Survey A and Survey C, but income data was not available for Survey B or the census, so it is difficult to ascertain which survey was more representative in this case.

When surface Concrete Face Rock fill Dam constructs than existent center core type rock fill dam, it is much prevalent form in domestic these day by quality control of that is profitable and weather condition etc. of coreZone. C.F.R.D is less research about seismic survey(Refractional Seismic Prospectin, Resistivity Prospecting) of levee body than fill dam. Thus as C.F.R.D seismic survey is less, safety of that consist is short most development flue is high reason. That is not checking target of minuteness safety diagnosis and so on by short operation period. Wish to analyze inquiry incidental and difference with center core type dam and acquire C.F.R.D preservation administration upper necessary inquiry condition forward hereafter.

Objectives : The aim of this study is to estimate traditional Korean medicine (TKM) practitioners' awareness and attitudes about acupuncture clinical study toward evidence based medicine (EBM). Methods : We conducted two surveys before and after the workshop. First survey, about the awareness and attitudes toward EBM was carried out with questionnaire. Second survey, about their changes in the attitudes toward EBM after the workshop was carried out with on-line questionnaire. Results : 70.0 % of respondents shows interest in the trends of clinical research. In contrast, 26.0 % of respondents used to search papers by themselves. 30.3 % of respondents reported that they apply the result of researches to their practice. 41.0 % of respondents thought that case study is needed for their practice, whereas 29.5 % responded that randomized controlled trial is most important. In the second survey, the attitudes toward EBM were changes positive. fair number of respondents usually get information from data regardless of EBM for their practice, but 23.5 % of respondents refer to the journals. Conclusions : The awareness and needs for education on the attendees toward EBM is quite high, and the effect of education is possibly influential. We expect the improvement on the refresher and the extension of education course for practitioners, and undergraduate curriculum.

Objectives: Sample surveys have been increasingly used by Korean medical doctors for many studies. We present how to conduct higher quality sample surveys in Korea. Methods: According to the 11 principal steps for sample surveys, the concrete issues that academic researchers tend to overlook are illustrated and a variety of methods for improving survey quality are discussed. Results: The survey statistics produced by some researchers could be subject to large errors. This would be mainly due to misunderstandings about the system of principles called survey methodology. The best strategy for avoiding these errors will be to follow the suggested guidelines. Conclusions: For the development of traditional Korean medicine, the role of survey studies is important. Conducting surveys of a better quality based on survey methodology will be beneficial to researchers.
