The purpose of this study is to compare the estimates of housework time by gender using two representative methods of time use study: Time Diary and Stylized Survey Questionnaire. Our analysis is based on the data from the Lifetime Use Survey(2004), which used time-diary questions, and the Korean Labor & Income Panel Study(KLIPS 2004), which used stylized questions on housework hours. The results show that men over-report their housework time in the stylized time use questions. In contrast, women under-report their housework time, which is unusual in the previous studies on response errors and reporting gap. Subgroup analysis shows that widowed/divorced men tend to over-report their contribution to housework more than other groups whereas among women, groups burdened with employed work, caring and housework underestimate their housework time. This reporting gap is explained by gendered norm and perception of time pressure. The theory to explain under-reporting of the housework time has been undeveloped in the previous studies. Our study suggests that perceptions of time pressure be an important factor to explain women's reporting gap of housework estimates.

How much do people living in different communities vary in their survey responses? A few studies have examined the effect of the social environment on survey response. Making generalizations from these studies by looking at the effect of social environment on survey response is complicated due to differences in survey dimensions, including incentives, survey mode, types of response rates, and geographic levels. Using the 2000 Census Final Response Rates(CFRR) and the 2002 General Social Survey Response Rates(GSSRR) linked with the 2000 Census in the United States, we attempt to understand how community characteristics associated with survey cooperation vary between data sets. We found that people living in poor area are less likely to cooperate with the Census but more likely to cooperate with GSS, while people living in an area with more minors under 18 is more likely to cooperate with both Census and the GSS. By using two data sources with contrasting survey dimensions within the United States, our findings have implications for survey field operations and hopefully will invigorate studies about response rates in a Korean context.

The purpose of this paper is to examine the effect of income-mix on place attachment as civic pride in Seoul. Place attachment and social mix are considered important in urban planning. However, place attachment is frequently thought to form more strongly in the homogeneous area. On the other hand, social mix policy is aimed to form more heterogenous area. So, the two concepts are thought to be incompatible. This paper focused on the income-mix which is kind of social mix, and used the 2013 "Seoul Survey" and 2010 "Household Travel Diary Survey" data. Based on the review of the literature, we used the civic pride in Seoul as the indicator of place attachment. The results of this paper indicate that the degree of income-mix increases, place attachment in Seoul also increases. Also, it appears that as regional income levels get higher, the effects of income-mix on place attachment decrease.

For a survey research in which the characteristics of the population of interest are investigated from a sample, representativeness of the sampling frame is one of the most important part to be considered. If the sampling frame fails to represent the population properly, statistical procedures based on the even efficient sampling design result in significant nonsampling biases and thus the statistical validities of the results could be damaged. But the construction of the reliable sampling frame that covers the population properly costs money and time and thus the sampling frame based on a census or a large scale survey is often used in practice. For example, the sampling frame based on the population households census is used for many household surveys in Korea. But due to the time difference between the census and a survey of interest, the sampling frame constructed from the census is expected to fail to cover the population of interest. Especially, one could expect a large amount of population and household movement in a large city like Seoul. Thus in our research, we considered the construction of new sampling frame and the procedure of sample selection for 2008 Seoul survey. We analyzed the sampling frame based on 2005 population households census and found that it does not represent the population properly. Thus, we proposed a new sampling frame based on resident registration DB for 2008 Seoul survey. We also proposed the sampling weights and estimator of the population mean based on the sample selected from the newly constructed sampling frame.

최근 인터넷 사용자의 급속한 증가와 더불어 인터넷 설문조사가 많이 시행되고 있다. 인터넷 설문조사는 적은 비용, 편리성, 짧은 설문기간 등의 장점을 갖고있지만, 전통적인 설문조사방법과 매우 다른 매체특성을 가지며 리서치 도구로서의 문제에 대한연구가 부족한 상황이다. (중략)

본 연구는 S/W 불법복제율 추정에서 미국의 IPR사가 제시한 방법에 대한 소개, 문제점등을 제시하고 그 대안으로 설문조사를 이용한 S/W 불법복제 추정 방법을 제안하였다. 연구결과 인터넷 설문조사를 이용한 S/W 불법복제 추정에는 4가지 방법이 가능하였으며 각각의 방법은 장단점이 있었다. 추후 연구에서 이러한 인터넷 서베이 방법들과 IPR사의 방법을 직, 간접적으로 비교하는 연구가 이루어질 것으로 기대된다.
