This study was carried out to raise research productivity through the analysis on the research projects and to find trends of mineral resources survey and mineral deposits of the KIGAM for 38 years since the fiscal year of 1976 to 2013. The KIGAM in the projects for mineral resources survey and mineral deposits expended 67.41 billion won for last 38 years, which is 107.07 billion won calculated using the present value in 2013 at discount rate of 5%. R&D expenditure in mineral resources survey and mineral deposits of KIGAM increased approximately 59.4 times from 108 million won in 1976 to 6,420 million won in 2013, and about 9.8 times from 657 million won in 1976, as calculated using the present value in 2013. The percentage of research projects in mineral resources survey by research sub-areas was as follows: survey, 32%(90 projects); origin of ore deposits and basic research, 19%(54 projects); exploration for ore deposits, 17%(48 projects); database and information, 13%(37 projects); mineralogy and ore analysis, 9%(25 projects); and etc., 10%(27 projects). Based on analysis of research trends over the last 38 years, to raise research productivity, the existing survey research techniques with repeated use and related technology development should be enhanced.

Telephone surveys miss, among other people, those who live in homes without telephones, people who are away from home at the time of interview and people who refuse to be interviewed. Recently, mobile phone survey has emerged as “A replacement technology” to the old telephone survey method. Mobile survey enables us to do many things we could not do or could not afford to do before, and reatly enhance the efficiency if the opinion surveys. Very specifically, the mobile survey enables us to control respondent's accessability, interviewer bias and to do incredibly fast and at a affordable costs. The authors analyze the results of mobile-phone local election polls and ELSI bio-technology attitude survey. The authors describe their results, the methods they used, including the use of demographic and propensity weighting to correct for substantial biases in the raw, unweighted data. The results show that mobile survey can predict the election outcomes with approximately equal accuracy to that of the telephone poll after weighting. This paper also cautions readers not to assume that mobile survey can be used with equal success in other elections and emphasizes the need for continuing research to improve mobile survey methods in the future.

The calibration methods of neutron-measuring devices such as the neutron survey meter have advantages and disadvantages. To compare the calibration factors obtained by the shadow cone method and semi-empirical method, 10 neutron survey meters of five different types were used in this study. This experiment was performed at the Korea Atomic Energy Research Institute (KAERI; Daejeon, South Korea), and the calibration neutron fields were constructed using a $^{252}Californium$ ($^{252}Cf$) neutron source, which was positioned in the center of the neutron irradiation room. The neutron spectra of the calibration neutron fields were measured by a europium-activated lithium iodide scintillator in combination with KAERI's Bonner sphere system. When the shadow cone method was used, 10 single moderator-based survey meters exhibited a smaller calibration factor by as much as 3.1-9.3% than that of the semi-empirical method. This finding indicates that neutron survey meters underestimated the scattered neutrons and attenuated neutrons (i.e., the total scatter corrections). This underestimation of the calibration factor was attributed to the fact that single moderator-based survey meters have an under-ambient dose equivalent response in the thermal or thermal-dominant neutron field. As a result, when the shadow cone method is used for a single moderator-based survey meter, an additional correction and the International Organization for Standardization standard 8529-2 for room-scattered neutrons should be considered.

This research presents an analysis of some of the occupations associated with Korea‘s national strategic industries. Therefore, the objectives of this paper can be summarized as follows: By classifying existing occupations and identifying potential future ones, this paper will strive to present a systematic analysis of environmental related occupations. In order to achieve the objectives of this research, related literature was examined, a Delphi Survey was conducted. In order to select potential future occupations, this research used a qualitative method that involved interviews with specialists. More specifically, a Delphi Survey was used to collect the specialists' opinions. The potential occupations were selected using a three-prong procedure involving an analysis of related literature and materials, a Delphi Survey, as well the holding of conferences with specialists and visits to those in the actual field. Through this process, 33 different potential future occupations were selected.

In order to make statistically valid inferences for survey data based on complex probability sample designs, survey researchers must incorporate the sample design in the data analysis If this in not the case the variance estimates of survey statistics derived under the usual simple random sampling assumptions from an infinite population generally underestimate the true variance, which results in high Type l error level. In this article we introduce new software packages dedicated to analyze complex survey data In particular, we summarize analysis capabilities on SUDAAN Version 7.5 and SAS Version 8.

Cyberspace permits us to more beyond traditional face-to-face, mail and telephone surveys, yet still to examine basic issues regarding the quality of data collection: sampling, questionnaire design, survey distribution, means of response, and database creation. This article address each of these issues by contrasting and comparing traditional survey methods(Paper-and-Pencil) with Internet or Personal Computer networks-mediated (Screen-and-Keyboard) survey methods also introduces researchers to this revolutionary and innovative tool and outlines a variety of practical methods for using the Internet or Personal Computer Networks. The revolution in telecommunications technology has fostered the rapid growth of the Internet all over the world. The Internet is a massive global network and comprising many national and international networks of interconnected computers. The Internet or Personal Computer Networks could be the comprehensive interactive tool that will facilitate the development of the skills. The Internet or Personal Computer Networks provides a virtual frontier to expand our access to information and to increase our knowledge and understanding of public opinion, political behavior, social trends and lifestyles through survey research. Comparable to other technological advancements, the Internet or Personal Computer Networks presents opportunities that will impact significantly on the process and quality of survey research now and in the twenty-first century. There are trade-offs between traditional and the Internet or Personal Computer Networks survey. The Internet or Personal Computer Networks is an important channel for obtaining information for target participants. The cost savings in time, efforts, and material were substantial. The use of the Internet or Personal Computer Networks survey tool will increase the quality of research environment. There are several limitations to the Internet or Personal Computer Network survey approach. It requires the researcher to be familiar with Internet navigation and E-mail, it is essential for this process. The use of Listserv and Newsgroup result in a biased sample of the population of corporate trainers. However, it is this group that participates in technology and is in the fore front of shaping the new organizations of interest, and therefore it consists of appropriate participants. If this survey method becomes popular and is too frequently used, potential respondents may become as annoyed with E-mail as the sometimes are with mail survey and junk mail. Being a member of the Listserv of Newsgroup may moderate that reaction. There is a need to determine efficient, effective ways for the researcher to strip identifiers from E-mail, so that respondents remain anonymous, while simultaneously blocking a respondent from responding to a particular survey instrument more than once. The optimum process would be on that is initiated by the researcher : simple, fast and inexpensive to administer and has credibility with respondents. This would protect the legitimacy of the sample and anonymity. Creating attractive Internet or Personal Computer Networks survey formats that build on the strengths of standardized structures but also capitalize on the dynamic and interactive capability of the medium. Without such innovations in survey design, it is difficult to imagine why potential survey respondents would use their time to answer questions. More must be done to create diverse and exciting ways of building an credibility between respondents and researchers on the Internet or Personal Computer Networks. We believe that the future of much exciting research is based in the Electronic survey research. The ability to communicate across distance, time, and national boundaries offers great possibilities for studying the ways in which technology and technological discourse are shaped. used, and disseminated ; the many recent doctoral dissertations that treat some aspect of electronic survey research testify to the increase focus on the Internet or Personal Computer Networks. Thus, scholars should begin a serious conversation about the methodological issues of conducting research In cyberspace. Of all the disciplines, Internet or Personal Computer Networks, emphasis on the relationship between technology and human communication, should take the lead in considering research in the cyberspace.

Survey environment has recently been changed along with its bad conditions. Surveyors feel difficult to meet respondents because the number of one person-household and working-together-household has rapidly increased. With a growing awareness of protecting personal information, respondents no longer want to response to a questionnaire. To get responses form an increasing number of non-response houses and respondents who are difficult to meet, Korea National Statistical Office(KNSO) has changed its survey methods and thus introduced new survey methods, free from face-to-face interviews. A telephone interview has officially been allowed for some reasonable situations and it shows a tendency that the trend of interviewing method is moving toward Internet survey. This paper focuses on how survey methods should be changed with the use of IT in response to changes in the survey environment. Survey methods combined with IT have many excellent advantages, Korea has been an enviable World IT contest for a long time. If Korea can apply such an advanced IT environment to survey methods successfully, it will make a great contribution toward improving the survey quality. This paper also reviews which survey method is most appropriate for National Statistics as the survey environment has changed.
