In this paper, the following facts have been reviewed: First, statistics should have the characteristics of descriptive, inferential, and applicative statistics in "information-Knowledge Society." Second, the computer has been employed in the process data collection and data analysis for producing the statistics with timeliness and efficiency. Third, we have to develop a statistical development plan which lays emphasis on the production of applicative statistics in the coming "Internet Cyber Society." In addition, we investigaated statistical survey methods. The prospects of internet surveys were also investigated here. On the basis of the above review and investigation. we suggested "an integrated system of computer-assisted statistical surveys" that can be applied to all kinds of surveys and statistics.nds of surveys and statistics.

Understanding the interplay between galaxies and dark matter in the universe is one of key challenges in modern astrophysics. This provides an important test of structure formation scenarios and cosmological models. I discuss three aspects of this test: (1) comparing the matter distribution from galaxy redshift surveys with that from weak-lensing surveys, (2) statistical comparison of large-scale structures between observations and cosmological simulations, and (3) multi-wavelength study of galaxies. These tests underscore the importance of combining photometric and spectroscopic surveys in observations along with cosmological simulations for exploring and understanding the structure formation.

This article explores the analysis of longitudinal surveys in which same units are investigated on several occasions. Multivariate exponential ratio type estimator has been proposed for the estimation of the finite population median at the current occasion in two occasion longitudinal surveys. Information on several additional auxiliary variables, which are stable over time and readily available on both the occasions, has been utilized. Properties of the proposed multivariate estimator, including the optimum replacement strategy, are presented. The proposed multivariate estimator is compared with the sample median estimator when there is no matching from a previous occasion and with the exponential ratio type estimator in successive sampling when information is available on only one additional auxiliary variable. The merits of the proposed estimator are justified by empirical interpretations and validated by a simulation study with the help of some natural populations.

Mixed-mode (or multi-mode) surveys and (volunteer) web panels were recently introduced as ways to cope with changes in the social survey environment, which is going through a rapid and massive transformation. The direction, speed, and magnitude of these changes have been clear in Korea, too. Enumerated in Figure 1 are the social surveys between 1960 and 2010 archived by the Korean Social Science Data Archive (KOSSDA) 2. The left panel shows the exponential growth in the overall volume. The other two panels, more importantly, show the changes in the composition. Mixed-mode and online surveys are rapidly increasing their shares and are fast becoming de facto standards in Korea, as in many other countries.

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.

Purpose : This study was done for reviewing problems in surveys on youth health risk behaviors in Korea and for looking for strategies to improve surveys of youth health risk behaviors through literature review. Method : This study reviewed foreign and domestic literatures. Results : The main problems were as follows; 1) lack of health risk behavior surveys focused on health behaviors, 2) differences in health risk behaviors surveyed, 3) inconsistency in the measurement on health risk behaviors, 4) lack of representativeness of the sample, using convenient sampling. Conclusions: Several suggestions were made for the future research, including establishment of systems for youth health risk behavior survey nationwide, introduction of internet survey, maintenance of consistency in health risk behaviors surveyed, investigation of relating factors relevant to health risk behaviors, and uses of survey results.

Today, as interest in the importance of urban parks increases, many citied internationally are actively creating small parks, but their maintenance systems remain ineffective. Accordingly, in this study, the limitations and problems in the operation and management of urban parks were derived by examining previous studies on overall urban park maintenance and management. Based on this, the study tried to understand the actual state of maintenance and management of small parks through data surveys and field surveys related to budget execution on case sites. Then, we sought to clarify the actual state of maintenance and management of small parks through data surveys and field surveys regarding the budget execution of case sites as a basis for research to prepare an efficient and systematic improvement plan for the maintenance management system of city parks.

From an ecological point of view, the western part of the Atlantic sector is one of the most productive areas in the Southern Ocean. Antarctic krill (Euphausia superba) and krill-dependent predators such as fish, seals, and birds are abundant there, and most krill fisheries have operated in this area since 1970s. The hottest issues for the proper management of krill resources nowadays are to determine total biomass in this area, and to identify environmental forces controlling stock fluctuation. This paper reviews and collates information on ongoing oceanographic activities in the Antarctic Peninsula region concerning these issues. To delineate the status and function of Antarctic krill population in Antarctic marine ecosystems, multinational researches along the Antarctic Peninsula area have been developing recently. Four member states of CCAMLR (Japan, Russia, UK, and USA) had conducted acoustic surveys in January-February 2000 (socalled CCAMLR-2000 survey), and krill standing stock at 120 kHz was estimated to be 44.29 million metric tonnes in the western Atlantic sector of the Southern Ocean. On the other hand, the Southern Ocean GLOBEC (SO-GLOBEC) Programme has prepared a serial winter survey to examine the factors that govern krill survivorship and distribution in relation to shelf circulation processes. Ship-based surveys using ice-breakers are being conducted by three nations (Germany, UK, and USA) around the Marguerite Bay during the austral fall and winter 2001 and 2002. In addition to these two large-scale surveys, some CCAMLR members have carried out joint oceanographic surveys near the South Shetland Islands to detect ecosystem changes since 1994. Especially from December 1999 to February 2000, in conjunction with CCAMLR-2000 survey, four nations (Japan, Korea, Peru, and USA) conducted acoustic surveys to produce time-series information on krill distribution and biomass near the South Shetland areas. Though the aims of each program and the approach to solve the scientific questions were different each other, the results from each program fill the gaps between programs. Further cooperation and exchange in these activities could be beneficial to each program.
