The purpose of this study is to estimate the housing area per capita for verifying if the public Big Data, of the building ledger and resident registration ledger, can be used as well as the National Census and Housing Survey. The Mankiw and Weil (MW) model was constructed by extracting samples of general detached houses and flat houses from the public big data, and compared with the result from traditional survey method. Then, the MW models of 25 municipalities in Seoul was established. As a result, it can be confirmed that it is possible to establish MW models comparable to regular surveys using public big data, and to establish a model for each basic localities which was difficult to use as a regular survey method. Public Big Data has the advantage of expanding the knowledge frontier, but there are some limitations because it uses data generated for other original purposes. Also, the difficult process of accessing personal information is a burden to carry out analysis. It is expected that continuing research should be needed on how public Big Data would be processed to complement or replace traditional statistical surveys.

The purpose of the study was to examine the restaurant workers' understanding of food hygiene and safety regulations using SPSS. From October 10th to 31st, 2008, a survey was conducted to those who work at family restaurants in Seoul and Gyeonggi-do. This program analyzed total 149 copies of the questionnaire. 79.9 percent of the respondents have completed college education; 76.7 percent out of them were domestic company workers and 82.9 percent were foreign company workers. The total average points turned out to be 14.03 points out of 20, 3.95 out of 5 for food poisoning, 2.37 out of 3 for personal hygiene, 6.41 out of 9 for food hygiene and environment, and 1.86 out of 3 for food safety. Foreign company employees scored higher points(14.3) compared to those of domestic companies. When comparing the points between domestic company workers and foreign company workers, the score of kitchen staff(p<0.001) and the score of a restaurant assistant(p<0.05) have influenced the overall points. In conclusion, people scored low points in areas as understanding of 'dangerous temperature level', 'bacterial multiplication', 'safe defrosting methods', 'cooling methods' and 'temperature control', indicating the necessity of the training on 'time/temperature control'.

This study finds a way to increase the usability of a subway commuter pass. Usability of the commuter pass on a probabilistic statistical model is calculated when the pass is allowed to used in a different mode(bus). A sunk cost of commuter pass is used to reduce the vehicle travels from public transit. 324 people aged 25 to 35 were surveyed and utilized to build a Nested Logit Model on STRADA 3.5 platform. Main results are as follows. First, commuter passes were issued in various forms. Second, the model turns out to be statistically significant in four explanatory variables (discount rate, inter-usablity between modes, forms of payment and periods). Lastly, the more valid on different modes, the more increased of the rail commuter pass.

황해의 대기환경을 종합적이고 체계적으로 조사하기 위해 한국과학기술연구원 지구환경연구센터를 중심으로 1998년 12월부터 황해종합조사사업의 일부로 "해양-대기 조사 연구"가 수행되었다 (이승복 등, 2002). 황해 전반의 대기오염 현황을 파악하기 위하여 본 연구팀에서는 황해상 도서인 덕적도에 고정 측정소를 구축하여 대기오염물질을 측정하고 있으며, 거의 직선적으로 황해를 가로지르며 항해하는 정기 여객선에 탐승하여 매년 대기오염물질을 측정하였고, 순회 조사선에 탑승하여 황해의 넓은 영역을 순회하면서 대기오염물질의 측정을 시도하였다(이승복 등, 2002; 김용표 등, 2000).

사전조사.분석은 사후분석 및 조치에 비해 매우 효과적이며 불필요한 예산의 낭비를 막을 수 있는 첩경이다. 전력증강에 종사하는 담당자들이 사전조사.분석의 중요성을 제대로 인식하지 못하고 소홀히 해 왔던 것이 사실이며, 이제는 전력투자사업에 대해 사업착수 전에 늦어도 사업추진 초기에 군 내부뿐만 아니라 외부의 전문가들과 종합적이고 전문적인 사전조사.분석을 수행하도록 해야 한다.
