As a way to serve housing information providing on internet will be a useful method in the near future in Korea. This study was planned to review the housing information on internet network which provided by U. S. .University CES(cooperative extension service) Comparative analysis was used as a Research method in terms of contents and items about housing information on internet provided by U. S. university CES during two weeks each in August 1997 and July 1998. Findings are as follows; Universities providing housing information and information items had been remarkably increased during one year since August 1997. Most of housing informations except one university CES were free to use in 1997 but three university CES among 12 universities showed only the title of items with charge amounts in 1998. Informations about 'Housing Management' and 'Environment' items were the large parts of the housing information in 1997. In 1998. 'Environment' items were remarkably increased. Items bout insects and mildew removing were large portion of the 'Housing Management'. Items about energy saving water and air quality were large portion of the 'Environment' These findings will be useful to develop items of housing information on internet network with Korean language which should be compensated by the survey research.

The first purpose of this paper was to investigate whether wives' income contributions affect the time spent on housework by dual-earner couples. The second purpose was to investigate period interaction effects on the effect of wives' income contributions. For this, Korean Time Use Survey data 2004-2019 was analyzed. The analysis target was dual-earner couple aged 20-59 years. The dependent variable was time spent on housework, and the analysis method was tobit regression. According to the results, there were three findings: First, there was a U-shaped relation between wives' income contributions and wives' housework time. Second, this relationship became stronger as time progressed. Third, although wives' income contributions positively affected husband housework time, husband housework time was actually zero before 2019. These results demonstrated that not economic perspective, but gender perspective, is more useful for understanding dual-earner couples' division of housework.

Objectives: This study aimed to evaluate the oral symptoms experiences of Korean adolescents among multicultural families. Methods: Data on 985 participants from the 16th Korea Youth Risk Behavior Web-based Survey were collected and analyzed using complex sample descriptive statistics. Results: The foreign-born mother, foreign-born parents, and foreign-born father rates were 77.2%, 17.3%, and 5.4%, respectively. The toothache, gingival bleeding, tooth fracture, and tooth sensitivity experience rates were 21.3%, 18.8%, 13.3%, and 30.4%, respectively. The tooth fracture rate was highest in the foreign-born parents group (24.6%). The toothache odds ratio (OR) was 1.71 (95% CI: 1.24-2.37) times higher in girls. The foreign-born mother group was 2.47 (95% CI: 1.09-5.60) times higher than that of the foreign-born father or both parents foreign-born groups. The smoking group was 2.03 (95% CI: 1.20-3.43) times higher than that of the non-smoking group. The gingival bleeding OR was 5.11 (95% CI: 1.80-14.53) times higher in the lowest economic status group. The tooth fracture OR was 3.44 (95% CI: 1.01-11.70) times higher in the lowest economic status group. The tooth sensitivity OR was 1.53 (95% CI: 1.14-2.04) times higher in girls. Conclusions: It is necessary to establish a program to promote oral health of adolescents from multicultural families.

There have been several studies on the key issues in information systems (IS) management. This study replicates the Society for Information Management (SIM) survey done in U.S.A. to investigate the key issues in IS management in Korea. This survey focused especially on the professions in financial institutions. A three-round Delphi method was employed to collect the opinions of participants and obtain a reasonable level of consensus about the key IS management issues of financial institutions in Korea. The number one issue identified was top management support, followed by recruitment and development of IS human resources. This article also compares the key IS management issues of financial institutions and those of manufacturing industries in Korea.

The objective of this study is to analyze the relationship between organizational capacity and the use of firefighter volunteers by volunteer fire departments within local/county governments. The study is based on a nonrandom sample of 213 U.S. volunteer fire departments within local governments. The fire chief of these fire departments responded to an annual survey conducted by Firehouse Magazine in 2010 and 2011. This study uses OLS regression analysis to assess the impact of organizational capacity (measured as annual budget) on the number of firefighter volunteers used by the volunteer fire department. There is evidence to suggest that organizational capacity has a positive and statistically significant effect on the number of volunteers used among U.S. volunteer fire departments. This study extends current literature on public volunteerism by analyzing factors that explain variation in the use of volunteers by local governments, specifically fire departments. Findings suggest that fire departments with greater resources in terms of revenue are more likely to use volunteers.

We have made a topological study of cosmic microwave background (CMB) polarization maps by simulating the AMiBA experiment results. A ACDM CMB sky is adopted to make mock interferometric observations designed for the AMiBA experiment. CMB polarization fields are reconstructed from the AMiBA mock visibility data using the maximum entropy method. We have also considered effects of Galactic foregrounds on the CMB polarization fields. The genus statistic is calculated from the simulated Q and U polarization maps, where Q and U are Stokes parameters. Our study shows that the Galactic foreground emission, even at low Galactic latitude, is expected to have small effects on the CMB polarization field. Increasing survey area and integration time is essential to detect non-Gaussian signals of cosmological origin through genus measurement.

Since mountainous area has access restrictions for field work, assessors need to establish a conceptual model of the contamination prior to the field investigation. In this study we established a conceptual model of the contamination based on site inspection and geological survey, followed by the field investigation for the petroleum spill site. In the conceptual model, we estimated that tile contamination should have spread by groundwater and topographical characteristics within the top soil layer. The spread of contamination through rock was not considered in the conceptual model due to impermeable characteristics of metasyenite. The contaminated environmental media of the petroleum spill site include soil and groundwater. According to the analysis result of the contamination, the volume of contaminated soil is estimated approximately 4, 150 cubic meters (7, 055 ton) with most contaminants existing along the groundwater flow within top soil layer.

We investigate the latent stage-sequential patterns of drinking behaviors of U.S. adolescents who have started to drink by age 14 years (seven years before the legal drinking age). A multiple-group latent transition analysis(LTA) with logistic regression is employed to identify the subsequent patterns of drinking behaviors among early-onset drinkers. A sample of 1407 early-onset adolescents from the National Longitudinal Survey of Youth(NLSY97) is analyzed using maximum-likelihood estimation. The analysis demonstrates that early-onset adolescents' drinking behaviors can be represented by four latent classes and their prevalence and transition are influenced by demographic factors of gender, age, and race.

In U.S.A., minimum wage of New Jersey in April 1, 1992 rose from $4.25 to $5.05. At this assession, there was survey by 410 numbers related back and pro minimum wage in New Jersey and eastern Pennsylvania.. At stores of New Jersey and eastern Pennsylvania, comparison of the increase of employment at constant minimum wag is with estimative effect of increase of minimum wage. Through comparison of stores of low wage and high wage above $5, employment volatility in New Jersey was studied. In U.S.A., increase of minimum wage was not caused to reduce to employment. Contrary to this, result of Korea was not consisted after timing of IMF bailout of 1997. It is because drop of revenue was caused to decrease employees of part-time and full-time job at the viewpoint of cost minimization.
