Background: Thyroid nodules may harbor cancer in 5% to 15% of cases. Specific clinical and sonographic features predictive of malignancy have been investigated in various populations, but due to differences in epidemiology, risk factors and iodine nutrition status, these predictors may not be valid in the Philippines. This study determined the clinicopathological, biochemical, and sonographic features of thyroid nodules predictive of malignancy among adult Filipino patients at the University of the Philippines-Philippine General Hospital (UP-PGH). Methods: We reviewed the medical records of Filipino patients ≥19 years of age who underwent thyroid surgery in UP-PGH from 2008 to 2011. Results: A total of 837 of 1,670 patients (50.1%) were enrolled in the study, which included 417 benign and 420 malignant tumors. The mean age at diagnosis was 38±11 years, with female predominance. Multiple logistic regression analysis showed that the presence of a hard or firm nodule (odds ratio [OR], 58.8, P<0.001; OR, 12.8, P<0.001), presence of microcalcifications (OR, 11.1; P<0.001), irregular margins on ultrasound (OR, 4.5; P<0.001), and absence of associated symptoms (OR, 2.3; P<0.002) increased significantly the likelihood of thyroid malignancy. Conclusion: Similar to international data, the absence of associated symptoms, firm to hard thyroid nodules, and the presence of microcalcifications and irregular margins were significant predictors of thyroid malignancy.
CAN THE MASSES OF ISOLATED PLANETARY-MASS GRAVITATIONAL LENSES BE MEASURED BY TERRESTRIAL PARALLAX?
Freeman, M.,Philpott, L. C.,Abe, F.,Albrow, M. D.,Bennett, D. P.,Bond, I. A.,Botzler, C. S.,Bray, J. C.,Cherrie, J. M.,Christie, G. W.,Dionnet, Z.,Gould, A.,Han, C.,Heyrovský,, D.,McCormick, J. IOP Publishing 2015 The Astrophysical journal Vol.799 No.2
<P>Recently Sumi et al. reported evidence for a large population of planetary-mass objects ( PMOs) that are either unbound or orbit host stars in orbits >= 10 AU. Their result was deduced from the statistical distribution of durations of gravitational microlensing events observed by the MOA collaboration during 2006 and 2007. Here we study the feasibility of measuring the mass of an individual PMO through microlensing by examining a particular event, MOA-2011-BLG-274. This event was unusual as the duration was short, the magnification high, the source-size effect large, and the angular Einstein radius small. Also, it was intensively monitored from widely separated locations under clear skies at low air masses. Choi et al. concluded that the lens of the event may have been a PMO but they did not attempt a measurement of its mass. We report here a re-analysis of the event using re-reduced data. We confirm the results of Choi et al. and attempt a measurement of the mass and distance of the lens using the terrestrial parallax effect. Evidence for terrestrial parallax is found at a 3 sigma level of confidence. The best fit to the data yields the mass and distance of the lens as 0.80 +/- 0.30 M-J and 0.80 +/- 0.25 kpc respectively. We exclude a host star to the lens out to a separation similar to 40 AU. Drawing on our analysis of MOA-2011-BLG-274 we propose observational strategies for future microlensing surveys to yield sharper results on PMOs including those down to super-Earth mass.</P>
Jeju World Peace Island Korean Peninsula Cruise: Planting the seeds of the Jeju King
Cherry Grant McCall 세계환경사회거버넌스학회 2022 World Environment and Island Studies Vol.12 No.2
The proposal in this paper outlines an idea for a Korean Peninsula focused Peace Cruise starting from Jeju World Peace Island and going up the eastern coast of the peninsula , taking in a port or two in Japan (such as Fukuoka) to accommodate potential Korean-descended passengers there and ending at Wonsan, where a grove of Jeju King Cherry (Prunus Yedoensis var. Nudiflora) trees could be planted progressively as a welcome avenue for those on the peace cruise ship. This grove of Jeju King Cherry trees will grow each time a Jeju World Peace Island Peninsula Cruise arrives. Wonsan has been a holiday place for the DPRK for some time and with the permission of that country could become a limited and controlled international destination for Peace and, perhaps, other cruise tours. There are precedents internationally for special zones to be declared for specific activities. Such places frequently become economic development zones for the host country. After successful itineraries have been shown, the Jeju World Peace Island ship could extend its cruise north to ports on the Kamchatka Peninsula and west to Chinese ports interested in the concept
