This study was conducted to investigate the incidence rate of metabolic syndrome, and the related factors were examined. 620 persons who had participated in both initial and second survey were selected. Initial survey was performed at the year of 2006 and second survey was performed at the year of 2010. Among them, 460 persons who didn't initially have a metabolic syndrome were selected as the final study subjects. They were classified into 2 categories; stationary normal group (352, 76.5%), and metabolic syndrome incidence group (108, 23.5%). The incidence rate of metabolic syndrome for the subjects was 25.2 per 1,000 person years. Sex, obesity, and smoking had significant effect on the incidence of metabolic syndrome. In multiple logistic regression analysis,after controlling variables, obesity index was found to be major factor in the incidence of metabolic syndrome. The risk of metabolic syndrome was increased by overweight or obesity. The strategy to control body weight should be emphasized for prevention of metabolic syndrome.

본 연구의 목적은 농산물 이력추적 시스템을 사용하는 생산자들의 시스템에 대한 만족과 지속적인 사용의도에 영향을 주는 요인을 파악하여 농산물 이력추적 시스템의 활성화를 위한 기초자료를 제공하는 것이다. 실증적인 검증을 위하여 재사용의도와 관련한 선행연구들을 검토하여 TAM과 ECT를 결합시킨 Extended ECT 모델을 제안하고 실제 농산물 이력추적 사업에 시범참여하고 있는 생산자 100명을 상대로 설문조사를 실시하였다. 분석 결과, 지각된 유용성 및 용이성, 수익성은 시스템 만족에 긍정적인 영향을 미치며 이는 지속적인 사용의도로 연결되었으나 지각된 용이성과 유용성이 직접적으로 지속적인 사용의도에 영향을 미치는 것은 아닌 것으로 나타났다. 이 결과는 농산물 외의 식품 이력추적 시스템에도 포괄적으로 적용이 가능하다.

The tracking and analysis of cell activities in time-lapse sequences plays an important role in understanding complex biological processes such as the spread of the tumor, an invasion of the virus, the wound recovery and the cell division. For automatic tracking of cells, the tasks such as the cell detection at each frame, the investigation of the correspondence between cells in previous and current frames, the identification of the cell division and the recognition of new cells must be performed. This paper proposes an automatic cell tracking algorithm. In the first frame, the marker of each cell is extracted using the feature vector obtained by the analysis of cellular regions, and then the watershed algorithm is applied using the extracted markers to produce the cell segmentation. In subsequent frames, the segmentation results of the previous frame are incorporated in the segmentation process for the current frame. A combined criterion of geometric and intensity property of each cell region is used for the proper association between previous and current cells to obtain correct cell tracking. Simulation results show that the proposed method improves the tracking performance compared to the tracking method in Cellprofiler (the software package for automatic analysis of bioimages).
