지난해 우리나라 기생충 감염율이 1.5%인 것으로 집계되었다. 변화의 추이를 보면 회충등 토양매개성 기생충은 감소하는 반면 요충, 간흡충 등의 감염율은 크게 감소하지 않은 실정인 것으로 밝혀졌다. 이 자료를 토대로 기생충 관리의 새롭고 구체적인 방향을 모색해 보기로 한다.

The aim of this study is to represent the residential population distribution in Seoul, Korea more precisely through the dasymetric mapping method. Dasymetric mapping can be defined as a mapping method to calculate details from truncated spatial distribution of main statistical data by using ancillary data which is spatial data related to the main data. In this research, there are two types of data used for dasymetric mapping: the population data (2010) based on a output area survey in Seoul as the main data and the building footprint data including register information as ancillary spatial data. Using the binary method, it extracts residential buildings as actual areas where residents do live in. After that, the regression method is used for calculating the weights on population density by considering the building types and their gross floor areas. Finally, it can be reproduced three-dimensional density of residential population and drew a detailed dasymetric map. As a result, this allows to extract a more realistic calculating model of population distribution and draw a more accurate map of population distribution in Seoul. Therefore, this study has an important meaning as a source which can be applied in various researches concerning regional population in the future.

It is important to scrutinize spatial patterns in crime analysis since crime data has geographical attribute in itself. We focus on the development of ¨Crime Analysis GIS¨ prototype which can discover spatial patterns in crime data by integrating mapping functions of GIS and spatial analysis techniques. The structure of this system involves integration of DBMS and GIS, and the major functions of the system include (i) exploring spatial distribution of point data, (ii) mapping hot-spot, (iii) clustering analysis of crime occurrence, and (iv) analyzing aggregated areal data. The process of design and implementation of this system is based on object-oriented methodologies. A web-based extension of the prototype using 3-tier architecture is currently under development.

국제연합은 매년 정기적으로 세계각국의 인구, 산업, 경제, 무역 기타에 관한 상당히 광범한 통계를 발표하고 있다. 그 중에서도 우리에게 가장 관계가 깊은 전력 및 에너지의 생산과 소비에 관한 새로운 통계자료가 최근에 발표되었다. 이 자료는 비종 통계가 발표되기 시작하면서부터 제10회째의 것으로서 전세계의 약 170 개국의 1965년까지의 실적이 국가별로 상세하게 분류되어 기재되어 있다. 비종 통계는 그 통계가 매우 힘이 드는 일일 뿐만 아니라 특히 공산권 제국의 수치는 파악하기가 상당히 어려운 실정이어서 결국 전체를 집계하는데는 1년 이상이나 걸리는 매우 힘든 사업이라고 할 수 있다. 아래에서 이 자료를 중심으로 하여 전력 및 일차에너지의 생산과 소비에 관한 세계 주요국의 개황을 소개하기로 한다.

Intelligent interpolation methods such as dasymetric mapping are considered to be the best way to disaggregate zone-based population data by observing and utilizing the internal variation within each source zone. This research reviews the advantages and problems of the dasymetric mapping method, and presents a geographically weighted regression (GWR) based method to take into consideration the spatial heterogeneity of population density - land cover relationship. The locally adaptive intelligent interpolation method is able to make use of readily available ancillary information in the public domain without the need for additional data processing. In the case study, we use the preclassified National Land Cover Dataset 2011 to test the performance of the proposed method (i.e. the GWR-based multi-class dasymetric method) compared to four other popular population estimation methods (i.e. areal weighting interpolation, pycnophylactic interpolation, binary dasymetric method, and globally fitted ordinary least squares (OLS) based multi-class dasymetric method). The GWR-based multi-class dasymetric method outperforms all other methods. It is attributed to the fact that spatial heterogeneity is accounted for in the process of determining density parameters for land cover classes.

During major elections, three terrestrial broadcasting stations in Korea have covered the progresses of election results by announcing the simple sum of ballot counts of all ballot counting stations. The current approach, however, does not properly reflect the actual ballot count differences by ballot counting location, leading to cause unnecessary but possible confusions. In addition, the current coverage approach restricts the broadcasters from using regional poll data gained through exit polls by letting them to use the significant information on a one-off purpose to announce the initial prediction of the poll results and to fully disregard the exit poll results during the ballot counting process. Based on the understanding, this paper is designed to suggest a Bayesian approach to consolidate the exit poll results with the progressive ballot counting results and announce them as such. The suggested consolidation approach is expected to mitigate or avoid the possible confusions that may arise in connection with the different ballot counting paces by ballot counting station.

Freight flow data in Korea has been collected for a variety of purposes by various organizations. However, since the representation and format of the data varies, it has not been substantially used for freight analyses and furthermore for freight policies. In order to increase the applicability of those data sets, it is required to bring them in a table and compare for finding the differences. Then, it is shown that the raw data can be aggregated by a particular criterion such as mode, origin and destination, and type commodity. This study aims to examine the freight data issue in terms of three different points of view. First, we investigated various freight volume data sets which are released by several organizations. Second, we tried to develop formulations for freight volume data. Third, we discussed how to apply the formulations to network models in which particular OR (Operations Research) techniques are used. The results emphasized that some data might be useless for modeling once they are aggregated. As a result of examining the freight volume data, this study found that 14 organizations share their data sets at various aggregation levels. This study is not an ordinary research article, which normally includes data analysis, because it seems to be impossible to conduct extensive case studies. The reason is that the data dealt in this study are diverse. Nevertheless, this study might guide the research direction in the freight transport research society in terms of data issue. Especially, it can be concluded that this study is a timely research because the governmemt has emphasized the importance of sharing data to public throughout 'government 3.0' for research purpose.

인쇄카드 시장은 지난해와 비교, 전반적으로 비슷했지만 내수시장에서의 경쟁은 가속화되는 가운데 수출실적이 소폭 증가한 것으로 나타났다. 또한 고급화되고 다양해지는 추세에 따라 수입물량은 다소 큰 폭으로 증가했다. 관세청이 집계한 자료에 따르면 올해 9월말 기준의 인쇄된 엽서 및 카드의 수출실적은 393만5천달러를 기록, 지난해 동기의 354만2천달러에 비해 11.1% 증가했고 수입실적은 204만8천달러에 달해, 전년 동기 149만5천달러보다 무려 37.0%가 늘었다.

한국제지공업연합회(회장 이종대)에서 집계한 자료에 따르면 양면아트지를 필두로 한 고품질 인쇄물에 활용되는 고급 인쇄용지의 생산 및 출하량은 지속적인 증가추세에 있는 반면에 교과서, 일반 책자, 공책 등에 사용되는 백상지나 중질지의 사용량은 주춤하거나 점차 감소하는 경향을 보이는 것으로 나타났다. 이러한 현상은 인쇄.출판물의 고급화 경향에 의한 것으로 이에 따라 제지업계들의 고품질 인쇄용지 개발 노력도 지속되고 있다.

It has been widely known that there are so many factors making travel demand errors in transportation forecasting steps. One of the reasons may stem from the level of aggregation of zone and network in analysis process. This paper investigates the effect of level of aggregation considering with number of zones in travel demand forecasting by expanding or reducing the zone and network gradually. Numerical results show that the aggregation could not make a significant impact on the travel demand, while disaggregation does. These results imply that a careful manipulation is required to add or to reduce zones and links in transportation planning process.
