In this paper, we conducted an empirical study to investigate the design and weighting effects on descriptive and analytic statistics. The design and weighting effects were calculated for estimates produced from the 1998 small firm survey data. We considered the design and weighting effects on coefficients estimates of regression model using the design-based approach and the GEE approach.

It is well known that vital statistics is of great importance as basic data for establishing various range of national policies. Especially, vital statistics is important among demographic information for monitoring and evaluating the population policy, for constructing life table, for making population projection, and for studying various aspects of the society. In principle, the production of vital statistics is based on the registration system. It is, however, still observed that there are some limitations in utilizing fully the registration system due to the inherent problems such as problems in its coverage, accuracies and timeliness. Thus, as an alternative, many countries conduct survey on vital statistics in order to supplement the registration system and obtain in-depth data. Korea is no exception in this aspect. The National Bureau of Statistics carries out the so-called Continuous Demographic Survey. This is a kind of multi-round retrospective survey, covering 32, 000 households and having reference period of one month. The survey has also characteristics of multi-subject sample. Thus, surveys on economic activity status of population, house-hold income & expenditure, and social indicators are together conducted with the same sample. It is, however, found that the survey itself tends to have some quality problems. Especially, the quality problems connected with field data collection are summarized as coverage error, non-response error and response error. Although it is inevitable not to be free from these errors, we should make all our efforts to reduce the errors. The probable schemes pointed out in this paper are as follows : 1) the strengthening formal quality control activities, 2) the review of the survey method, i. e., the combining interview method with mail-sending and mail-back method or pick-up method, 3) well documentation for various cases found in every stage of data collection, and 4) the strengthening the analytical activities. It is, also, emphasized that sincerity of planners and interviewers is the most important factor among other things.

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.

Homelessness is recognized as a problem of lack of housing as well as a social problem entangled by complex problems such as unemployment, family breakdown, social exclusion, health and suicide. In order to search for the specificity of any particular addiction type, we conducted a survey on the addiction and mental health status of the homeless. One of our findings indicated that alcoholism was mainly found more in older homeless; however, internet game and smart phone addiction was found more in younger generations. We hope that our study is meaningful as a typification work at the current stage because there have been few studies in Korea on homeless youth and no study about homeless people's addiction problems other than alcoholism.

Purpose: Over the past two years, most Korean nursing students had to go through distance learning due to the COVID-19 pandemic. During the pandemic, amental health crisis has emerged among nursing students in South Korea. The study aimed to examine the relationships among social contact, depression, loneliness, and suicidal ideation. Methods: A cross-sectional survey design was used to collect data from nursing students. The survey was conducted onlinein South Korea. A total of 184 nursing students were recruited from December 2021 to April 2022. For data analysis,the frequency, percentage, mean and standard deviation of the general characteristics of the subjects were calculated using IBM/SPSS Statistics 25.0. To examine the mediating effect of depression and loneliness on the relationship between social contact and suicidal ideation, multiple linear regression was used to analyze associations among social contact, depression, loneliness, and suicidal ideation. Results: The average age was 22.69±5.66 years (range=18~54), and the sex distribution was 155 females among 184 nursing students. Lower social contact among nursing students was significantly associated with higher depression and loneliness. Loneliness significantly mediated the relationship between social contact and suicidal ideation innursing students. Conclusion: The findings suggest that strategies for enhancing social contact and reducing depression and loneliness should be considered to improve suicidal ideation among nursing students.

This study aims to discuss the role and function of social capital in explaining social risk perception among female-headed households. This study analyzed the level of social risk perception and its determinant factors of female-headed households using 2020 Social Survey data from Statistics Korea. The analysis revealed that socio-demographic factors and social capital influenced the perception of social risk. In addition, the social capital related to social safety was associated with the level of social risk perception. Even after controlling for various factors, the social risk perception level among female-headed households was higher than among male-headed ones. Among female-headed households, social capital such as compliance with regulations or ability to cope with risk; demographic factors such as age, residential area, and health status; and economic factors such as income level and housing type were found to affect social risk perception. Based upon the findings this study devises ways to accumulate social capital that can be obtained in cooperative relationships between families and communities.

The purpose of this study was to investigate the differences in time use between Korean and American high school students. The data sources were the '2009 Time Use Survey' conducted by Korea National Statistical Office and the '2009 ATUS (American Time Use Survey)' conducted by Labor Statistics Division in the U.S.. 1,734 Korean diaries (1,311 on weekdays and 423 on Sundays) and 321 American diaries (208 on weekdays and 113 on Sundays) from high school students of 15 to 18 years of age were analyzed. Descriptive statistics and t-test were used for the statistical analysis. The time use patterns of Korean students on weekdays and Sundays were different than those of their American counterparts. On weekdays and Sundays, the sleeping time of Korean students was 2 hours less than the time of their American counterparts. Koreans studied more, nearly double the time of their American counterparts on weekdays and five times more on Sundays. The study-oriented time allocation of Korean students resulted in less leisure time than the American students. Korean students spent their leisure time of more than 30 minutes participating in social activities, media, and hobbies, and their time allocation to volunteer work and religious activities were nil. On Sundays, the time for studying by Korean students was more than five times longer than that spending by their American counterparts. Koreans used their leisure time of 6 hours and 47 minutes mainly for media, hobbies and social activities. The participation rate of volunteering by Korean students was only 0.5%, though it was 31.0% for the Americans. For a study-life balance for Korean students, it was recommended that trends toward time management and social policy should increase the time allocation to sleeping, housework, work, sports, and volunteering and decrease the time use in studying and hobbies.
