Background: Nasopharyngeal carcinoma(NPC) is a commonly diagnosed cancer in Southeast Asia. Many studies have examined the risk factors for NPC, yet the roles of some risk factors remain inconclusive. The purpose of this study was to examine associations between modifiable lifestyle factors and the risk of NPC in the Singaporean ***: We conducted a case–control study in Singapore with 300 patients and 310 controls who were recruited between 2008 and 2012. Each control was selected and individually matched to each patient based on sex, ethnicity, and age(±5 years). A total of 290 pairs of cases and controls were matched successfully. We examined lifestyle factors such as tobacco smoking, alcohol drinking, various salted and preserved food consumption, and weaning ***: After adjusting for covariates, multivariate analysis showed that those participants who were current smokers and had ever smoked tobacco had a higher risk of NPC than participants who had never smoked, with odds ratios(ORs) of 4.50(95% confidence interval [CI] 2.58–7.86; P < 0.001) and 2.52(95% CI 1.54–4.12; P < 0.001), respectively. Those who consumed salted vegetables at least once a week also showed a significantly increased risk of NPC than those who never or rarely consumed salted vegetables, with an OR of 4.18(95% CI 1.69–10.38; P = 0.002).Conclusion: Smoking(currently and ever-smoked) and consuming salted vegetables once a week or more were lifestyle risk factors for NPC, and changes of these factors for the better may reduce the risk of NPC.

背景与目的鼻咽癌(nasopharyngeal carcinoma,NPC)是东南亚地区一种常见的癌症。许多研究已经对NPC的风险因素进行了研究,但一些风险因素的作用仍无定论。本研究旨在探讨新加坡人可改变的生活方式因素与NPC风险之间的关系。方法我们在新加坡进行了一项病例对照研究,在2008年至2012年期间招募了300例患者和310例对照。根据性别、种族和年龄(±5岁)对各例对照进行选择并分别与每一例患者匹配。共有290对病例和对照成功匹配。我们对多个生活方式因素,如吸烟、饮酒、各种腌制和罐头食品消费以及断奶习惯进行了研究。结果调整协变量后多因素分析显示,现行吸烟者和有既往吸烟史的参与者比从未吸烟的参与者患NPC的风险更高,优势比(odds ratios,ORs)分别为4.50 [95%置信区间(confidence interval,CI):2.58–7.86;P <0.001]和2.52(95%CI:1.54–4.12;P <0.001)。每周至少吃1次腌制蔬菜的人也比那些从不或很少食用腌制蔬菜的人表现出NPC风险显著增加,OR值为4.18(95%CI:1.69–10.38;P=0.002)。结论吸烟(现行和经常吸食)和每周1次或多次食用腌制蔬菜是NPC的生活方式风险因素,戒除这些不良因素可以降低NPC的风险。

Operational Implementation of the ATOVS Processing Procedure in KMA and Its Validation

Advances in Atmospheric Sciences 2003年第3期20卷 398-414页

作者： Myoung-Hwan AHN Mee-Ja KIM Chu-yong CHUNG Ae-sook SUH RemoteSensing Research Laboratory/Meteorological Research Institute RemoteSensing Research Laboratory/Meteorological Research InstituteRemoteSensing Research Laboratory/Meteorological Research InstituteRemoteSensing Research Laboratory/Meteorological Research Institute Seoul 156-720KoreaSeoul 156-720KoreaSeoul 156-720KoreaSeoul 156-720Korea

The Korea Meteorological Administration (KMA) has processed the data from the advanced TOVS (ATOVS) onboard NOAA-16 satellite since May 2001. The operational production utilizes the AAPP (ATOVS and AVHRR Processing Package) of EUMETSAT and IAPP (International ATOVS Processing Package) of the University of Wisconsin. For the initial guess profiles, the predicted fields (usually 6 to 12 hour forecasted fields) from the global aviation model of NOAA/NCEP are used. The average number of profiles retrieved from the ATOVS data is about 1,300 for each morning and afternoon orbit at about 18 and 06 UTC, respectively. The retrieved temperature and dew point temperatures are provided to forecasters in real time and used for initialization of prediction models. With the advanced microwave sensor (AMSU; Advanced Microwave Sounding Unit), accuracy of the ATOVS products is expected to be better than that of the TOVS products, especially in cloudy conditions. Indeed, the preliminary results from a validation study with the collocated radiosonde data during a 8-month period, from May to December 2001, for the East Asia region show an improved accuracy of the ATOVS products for cloudy skies versus the TOVS, especially for higher altitudes. The RMS (Root Mean Square) difference between the ATOVS products and radiosonde data is about 1.3°C for both clear and cloudy conditions, except for near the ground and at higher altitudes, at around 200 hPa. There is no significant temporal variation of the error statistics at all pressure levels. In case of the water vapor mixing ratio, the largest difference is shown at lower altitudes, while the accuracy is much better for the clear sky cases than the cloudy sky cases. The bias and RMSE at lower altitudes is about 0.557 g kg−1 and 2.5 g kg−1 and decrease significantly with increasing altitude.

Comparative analysis on homogeneity of Pb and Cd in epoxy molding compounds

Transactions of Nonferrous Metals Society of China 2011年第A01期21卷 160-164页

作者： Kyun-Gmee LEE yong-Keun SON Jin-sook LEE Tai-Min NOH Hee-Soo LEE Department of Chemistry Sungkyunkwan University Department of Chemistry Yonsei University School of Materials Science and Engineering Pusan National University

Reference materials for quantitative determination of regulated heavy metals, such as Pb and Cd in electronic components, were designed and investigated in terms of stability and homogeneity. Reference materials with two concentration levels of heavy metals were prepared by spiking Pb and Cd compounds to epoxy molding compounds made by mixing silica powders and epoxy resin. The concentration changes of the reference materials during stability test for 1 a were not observed. In the homogeneity assessment, the as-prepared reference materials were studied by using three different analytical tools, inductively coupled plasma atomic emission spectrometry (ICP-AES), X-ray fluoroescence spectrometry (XRF) and laser ablation ICP mass. The results show different homogeneities by the characteristics of analytical tools and the materials.

作者： Shin-Heon Lee Myeong-Jin Ko Taek-Kyun Nam Jeong-Taik Kwon yong-sook Park Department of Neurosurgery College of MedicineChung-Ang UniversitySeoul 06973South Korea

Background: The relationship between physical and psychopathological features in complex regional pain syndrome(CRPS) has been a subject of constant interest, but no data are available in adolescents. Therefore, we aimed to identify the factors associated with psychopathology in adolescents with CRPS ahead of military ***: We retrospectively reviewed all conscription examinees who had completed a Military Personality Inventory(MPI) during a period between February 2013 and December 2016. A total of 63 persons with a history of CRPS(19-years of age for all) were enrolled. Basic demographic and pain-related data were analyzed to examine their association with MPI results. The mean FGR score as well as the 8 subdomain scores were compared between those with pain duration at <15 months(n=30) vs. ≥15 months(n=33). Binary MPI results(normal-abnormal) were also compared between the two ***: In multivariate analysis, abnormal MPI was associated with pain duration, with an odds ratio(OR) at 1.05 for every 1-month increase [95% confidence interval(CI) 1.02–1.08;P=0.002]. Subjects with pain duration at ≥15 months have lower faking good response score(P<0.001 vs. those with pain duration at <15 months), and higher abnormal MPI result rate, faking bad response, inconsistency, anxiety, depression, somatization, paranoid, personality disorder cluster A, and personality disorder cluster B scores(P<0.05). Pain duration was significantly associated with the MPI ***: Pain duration is associated with psychopathology in adolescents with CRPS. Psychopathologic features increased as the disease duration increased. A comprehensive understanding of time-dependent psychopathological factors could support the planning of multimodal approaches for managing adolescent CRPS.
