Background and Objectives: As shown in previous studies, pentraxin 3 (PTX3) can be a useful inflammatory marker for metabolic syndrome and central obesity.Serum PTX3 levels are also an independent factor associated with visceral fat area.The aim of this study was to assess the role of PTX3 as an inflammatory maker in patients with central obesity undergoing primary percutaneous coronary intervention (PCI) following an ST-segment elevation myocardial infarction (STEMI).Sub- jects and Methods: From December 2007 to June 2008, 40 subjects (mean age: 61±11 years, M : F=34 : 6) with STEMI who underwent primary PCI were enrolled.We determined waist circumference, waist/hip ratio, body mass index (BMI), and visceral and total fat area via fat computed tomography (FAT-CT), and compared them with serum PTX3 concentrations.Results: The serum PTX3 concentration was closely related to FAT-CT-estimated visceral fat area (r=0.41,p<0.01) and total fat area (r=0.38,p=0.01), respectively.The serum PTX3 concentration was not related to waist circumference (r=0.27,p= 0.20), waist circumference/hip ratio (r=0.25,p=0.16),BMI (r=0.04,p=0.80) and lipid profiles, respectively.Among the parameters determining metabolic syndrome, an increasing visceral fat area had the strongest association with PTX3 concentrations. Conclusion:In patients with STEMI, PTX3 is associated with central obesity and it is significantly and independently correlated with visceral fat area.FAT-CT-estimated visceral fat area is the most reliable factor associated with serum PTX3 levels in patients with STEMI and central obesity.

This study examined the expectations and attitudes toward retirement, and financial planning for retirement among paid workers aged 20s and 30s. It compared paid workers' socio-economic, and retirement-related characteristics between those who had retirement planning and those who did not, and identified factors important to retirement planning decision. Data for this study were from a questionnaire completed by paid workers in age 20s and 30s (n=227), and were analyzed by t-tests, chi-square tests, and a logistic regression model. The findings of this study were as follows: First, the paid workers' expected retirement age was 56, and their ideal age for retirement was about 60. More than 85% of workers agreed that the retirement planning should begin before age 40, but just 51 % of the workers had retirement planning. Second, the workers aged 30s, married, and those who had higher incomes and home ownership were more likely to prepare financially for their retirement. Third, as their expected retirement age increased, the probability of decision to retirement planning increased. Those who expected that the economic status of retirees' living would be same as their current economic status were more likely to have retirement planning. The positive attitudes toward retirement had significant effect on the decision to have retirement planning.
서울시도의 경우 자치구 관할 도로에 비해 관리상의 중요도에 차이가 있고, 교통량 및 포장두께가 다르며 도로파손으로 인한 포장상태 저하율이 상이하기 때문에 기존 서울시도의 엄격한 관리기준을 자치구도에 적용하는 것은 바람직하지 않다. 본 연구에서는 서초구의 한정된 도로포장 유지보수 예산으로 보다 합리적이고 효율적인 포장상태 평가 및 관리를 위해 서울시도 PMS(Pavement Management System) 체계인 SPI(Seoul Pavement Index) 평가방법에 기반 하여 자치구도 포장평가방안을 제시하였다. 기존 시도SPI의 주요 변수인 균열율(Crack), 소성변형(Rutting), 평탄성(IRI)에 대한 관리기준을 구청 도로관리 기준에 맞도록 완화시키고, 제안한 각각의 포장파손 공용성 모형에 적용하여 포장상태계수를 산정하였으며, 또한, 설계시 공용성과 실제 공용성과의 차이점과 함께 준공 시 도로포장 상태도 반영되도록 수정하였다. 최종적으로 서초구 포장종합평가 모형식은 서울시의 모형식과 동일하게 각각의 공용성능 항목인 균열, 소성변형, 평탄성을 동등한 비율로 설정하여 도로포장의 전체 공용성에 영향을 주도록 설정된 제안 SPI를 개발하였다. 따라서 시도SPI보다 완화된 기준 및 설계와 시공현장상태를 반영한 구도SPI를 활용한다면 보다 합리적인 서초구도 포장의 합리적인 유지보수를 시행할 수 있을 것이다. Adapting the maintenance criteria of Seoul City pavement is not applicable for borough pavement due to differences between the pavement of Seoul city and the borough, such as priority of maintenance, traffic volume, thickness of pavement, and pavement deterioration rate by distresses. To develop an efficient and reasonable evaluation method of the Seocho borough pavement condition within a limited budget, this study suggested the borough pavement condition evaluation model based on the PMS (Pavement Management System) of Seoul Metropolitan SPI (Seoul Pavement Index). The SPI was modified to predict the remaining life and determine the proper maintenance method for the pavement in Seocho borough. This was suggested to reflect the rate of the designed performance life and field performance life of pavement as well as the pavement condition at the stage of the completion of construction. Primary variables, such as crack, rutting and IRI in the final model affect the overall performance life due to their even composition. Therefore, the suggested model considering the lowered criteria, design performance factor, and construction factor can be used for the more efficient maintenance of Seocho borough pavement.
