Dealing with uncertainty has been a critical issue in demographic and population forecasting since 1980. This study reviews methodological developments in demographic and population forecasting over the last several decades. First, this study reviews the important issue of the uncertainty surrounding demographic forecasts. Several limitations of the traditional scenario approach to dealing with uncertainty are also discussed. Second, in forecasting demographic processes such as mortality, fertility, and migration, three approaches of stochastic forecasting are identified and discussed: expert judgment, statistical modeling, and analysis of historical forecast errors. Finally, this study discusses the current issues and directions for future research in stochastic demographic forecasting.

While there have been lots of researches on the use of cyber money in online business area, few studies suggested the results on relationship between individual characteristics, including demographic and cyber money usage characteristics, and quality factors of cyber money. Therefore, this study investigates which quality factors of cyber money are perceived to be important, and examines whether the perception of cyber money quality will vary by individual characteristics such as gender, age, cyber money usage frequency, and cyber money usage volume. The results show, based on the statistical analyses using survey questionnaire for cyber money users living in the Seoul metropolitan area, that there are differences in perception of required quality factors of cyber money among the respondents grouped by gender, age, and usage frequency of cyber money. This study could propose a variety of implications for future researches on the use of cyber money in online business areas of home and abroad.

This study aimed to look into a comparison of the demographical characteristics concerning behavior toward the consumption of and satisfaction with Korean foods, and intention to repurchase Korean foods by identifying the food-related lifestyles of Korean consumers. As a result of research, food-related lifestyle was divided into five dimensions, namely the pursuit of health, convenience, safety, economic efficiency, and the pursuit of taste factors. Consumers' food-related lifestyles were confirmed to exhibit a significant difference according to demographic characteristics, such as gender, residential area, age, occupation, educational background, and income, and to the characteristics of their consumption behavior of Korean foods. In detail, the food-related lifestyles of consumers in their twenties showed a higher tendency for convenience and the pursuit of taste factors, and consumers in their forties or over were likely to pursue both economic efficiency and taste factors at the same time. Overall, the pursuit of safety was discovered as being the highest tendency. Also, the food-related lifestyle that most significantly affected satisfaction with Korean foods appeared to be health and the pursuit of taste factors, and satisfaction were found to have a significant effect on the intention to revisit.

As the use of mobile devices such as PDAs and smart-phones increases, the Mobile Payment System(MPS) is widely used as a new payment method. Accordingly, domestic and foreign MPS users can conveniently purchase or use the products and services they want, free from the constraints of time and space. In this situation, the study was to investigate how the perception of MPS value varies depending on the characteristics of MPS users(demographic characteristics, MPS usage characteristics), and to analyze whether the perception of MPS value ultimately has a significant effect on user satisfaction. To accomplish these research purposes, the study conducted a statistical analysis using a questionnaire for people with experience using MPS in Korea. The analysis results of the study could be useful in seeking ways to successfully spread of MPS at home and abroad and improve user satisfaction in the future.

This paper discusses transformation of the US population census since 1990 and its future prospects by mentioning the 2000 census experience and the 2010 census plans. First, it examines the recommendations written for the 2000 census by the Committee on National Statistics, National Research Council, such as introduction of statistical estimation, response rate improvement, long form improvement, adjustment in differential undercount by race/ethnicity, alternative census methods, collection of small-area statistics in non-census years, and census frame enhancement, and describes how the US Supreme Court decision of 1998 led the Census Bureau to fail in conducting the US version of One Number Census which uses statistical estimation by matching actual enumerations from the Census main survey and post-enumeration survey. Second, it examines one key element of the 2010 U. S. census, say, the separation of long form from short form and describes the main features of American Community Survey, a rolling census which replaces long-form component of the traditional US "Decennial Census" Another element is MAF/TIGER Enhancement Program which aims to improve enumeration accuracy in the traditional short-form census and help the Census Bureau introduce a mobile computer system as part of high-tech census operation. In this paper, it is pointed out that the separation of long form from short form is not an accidental one which results from the US Supreme Court decision, but the Census Bureau at this time in 2008 worries about the accuracy of enumeration because it has failed to develop a mobile computer system and will have to canvass 115 million households by paper and pencil by hiring 600 thousand temporary census workers.
