The paper aims to evaluate the quality of fisheries census statistic and to provide some desirable directions and improvements for the future fisheries census, conducted by the Government. For the quality diagnosis of fisheries census statistic, specific processes of fisheries census and statistical qualities of each dimension are surveyed and evaluated by a Government's practician, two external examiners and a research group. Results show that census design, data analysis and quality control are evaluated relatively low in specific processes, and accessibility and comparability are evaluated relatively lower than relevance, accuracy, timeliness and consistency in statistical qualities. For minimizing the sampling errors, the probability proportion method should be employed in sampling methods from currently simple sampling method. In addition, fisheries census statistic is desirable to include and compare with those of different countries for consumer oriented data system.

The purpose of this research is to define the problems of the Fisheries Census of Korea and to make better policies for improvement. In order to complete the purpose, the research team has firstly conducted a survey in the six regions to reinvestigate the yes or no for accuracy of the primary data related to the Fisheries Census. Moreover, the team has defined the problems of the Fisheries Census through conducting a survey for the experts and users of the fisheries statistics. Also, the team has derived the short/long term improvement of Fisheries Census through out this survey. This study has proposed that the name of census should be changed from the Fisheries Census to the Fishing Industry Census, the owners of distribution & processing companies, and their employees should be included in order to figure out the total size of the fishing industry and to plan right policies. In addition, the right information can evaluate the long-term planning for the fishing industry. The proposals from this study require a lot of changes on the Fisheries Census; so, it is impossible to adopt the proposals right from the Fisheries Census of 2015. Therefore, the changes should be adopted from the next Fisheries Census.

The empty houses' problem is important in the local revitalization and local sustainability, and these phenomenon caused by various factors of the region. The population and housing census data are the most effective data available to study this phenomenon by small regions. In this study, logistic regression and multiple regression analysis were performed to understand the effects of population, household, and housing characteristics on empty houses using population and housing census data. Also, the scale and direction of the effect of each characteristic in large cities, small cities, and rural areas were compared. As results, there was a slight difference between cities and province regions in the district and housing characteristic variables. In the comparison of Eup-Myeon-Dong, the affected variables were different in the Dong and Myeon areas. The significance of this study is to examine the effect of the characteristics of population and housing on the vacant houses and to confirm that the factors affecting different regions.

It is important to obtain the information of population center for establishing the balanced development policy of a nation. In this note, the population center of Korea is obtained using 2010 Census data and compared with the past population centers. The weighted average method is used for calculating the population center. The results of this note will be able to contribute in the regional population distribution policies.

인구주택총조사는 국가기본통계조사로서의 중요성과 필요성에도 불구하고 여러 가지 조사실행의 현실적인 어려움에 직면하고 있다. 많은 조사비용과 수집되는 정보의 양의 감소, 그리고 긴 조사 주기 등이 현행 총조사에 제기되는 문제점들이다. 이러한 문제점을 해결하는 전통적인 총조사의 대안의 하나로 순환총조사가 대두되었다. 순환총조사에서는 국가 전체를 여러 해에 걸쳐 조사하므로 조사결과를 자주 생산하여 시의성이 개선되고 조사비용을 균등 분배할 수 있는 장점이 있다. 반면, 한 순간에 국가 전체를 조망하는 특성이 상실되고 현장조사에서 외부의 영향이 증가할 수 있는 단점이 있다. 이 논문에서는 순환총조사의 사례로 프랑스 순환총조사와 미국지역사회조사를 구체적으로 살펴보았다. 그리고 현행 총조사의 대안으로 순환총조사를 도입할 때 검토해야 하는 사항 중, 순환표본 선정, 모집단 갱신, 합성추정, 순환표본 실행에 대하여 고찰하였다.

One of the main objectives of the U.S. Census Bureau is the proper estimation of median household income for small areas. These estimates have an important role in the formulation of various governmental decisions and policies. Since direct survey estimates are available annually for each state or county, it is desirable to exploit the longitudinal trend in income observations in the estimation procedure. In this study, we consider Fay-Herriot type small area models which include time-specific random effect to accommodate any unspecified time varying income pattern. Analysis is carried out in a hierarchical Bayesian framework using Markov chain Monte Carlo methodology. We have evaluated our estimates by comparing those with the corresponding census estimates of 1999 using some commonly used comparison measures. It turns out that among three types of time-specific random effects the small area model with a time series random walk component provides estimates which are superior to both direct estimates and the Census Bureau estimates.

Recently, the importance of livestock statistics is increasing because of the food consumption pattern in Korea is changing. We compare the old sample design based on the 1995 National Agriculture Census with the new sample design based on the 2000 National Agriculture Census. We present some considerations to improve the efficiency of the sample design in livestock sector survey.

본 연구의 목적은 센서스자료를 수치지도와 결합하여 도시 환경분석에 활용하기 위하여 이들의 보완 및 활용에 대한 기초연구를 수행하는데 있다. 센서스자료의 보완을 위하여 가구소득과 주택가격을 조사항목에 첨가할 것과 미국의 PUMS와 같은 1~5%의 표본조사를 제안하였으며, 센서스 최소분석단위를 현재의 읍 면 동 단위에서 이를 5~10지역 정도로 세분화한 인구 5,000명 정도를 기준으로한 센서스트랙을 제안하였다. 수치지도의 빠른 제작과 원활한 활용을 위해서는 지자체들이 1:1000 혹은 1:1200 축척 수치지도들을 자체 제작하려고 노력하는 대신에 국립지리원 제작의 1:5000 축척의 수치지도를 기본도로 활용하여 재정상의 부담을 줄이면서 빠르게 TIGER File화 할 것을 제안하였다.

The purpose of this study is to maintain the existing characteristics of the city by utilizing the physical decline status and floating population in small and medium cities residential areas. In addition, it intends to present the direction of flexible urban regeneration and maintenance by reflecting regional characteristics and current status. A total of three data were used in this study. Building data, floating population data, and census output area data were used. Building data and floating population data were classified into five classes. The graded data were joined to the census output area data and analyzed by overlapping the two data. As a result of analysis of 17 residential areas in 5 small and medium cities in Jeollanam-do, 4 types, 2 management models, and 4 indicators could be presented by grade and regional characteristics. This study is meaningful in that it is possible to plan regionally customized urban regeneration/maintenance management plans and projects through the typology of the current status and characteristics of the region, which is an important step in the bottom-up form.

Epidemic models are used to analyze the spreading of epidemic diseases, estimate public health needs, and assess the effectiveness of mitigation strategies. Modeling scope of an epidemic model ranges from the regional scale to national and global scale. Most of the epidemic models developed in Korea are at the national scale using the equation-based model. While these models are useful for designing and evaluating national public health policies, they do not provide sufficient details. As an alternative, individual-based models at the regional scale are often used to describe disease spreading, so that various mitigation strategies can be designed and tested. This paper presents an individual-based epidemic spreading model at regional scale. This model incorporates 2005 census data to build the synthetic population in the model representing Daejeon in 2005. The model's capability is demonstrated by an example where we assess the effectiveness of several mitigation strategies using the model.
