        Clinicopathological, Biochemical, and Sonographic Features of Thyroid Nodule Predictive of Malignancy among Adult Filipino Patients in a Tertiary Hospital in the Philippines

        Edwin Jadulco Cañete,Cherrie Mae Sison-Peña,Cecilia Alegado Jimeno 대한내분비학회 2014 Endocrinology and metabolism Vol.29 No.4

        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

        HIGH YIELD PREPARATION OF FULLERENE NANOWHISKERS AND NANOTUBES BY THE SOLUTION ROUTE

        CHERRY L. RINGOR,KUN'ICHI MIYAZAWA 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2008 NANO Vol.3 No.5

        The effect of ultraviolet, visible and near-infrared irradiation on the yield and morphology of single crystalline C60 fullerene nanowhiskers (FNWs) and nanotubes (FNTs) was investigated in an effort to produce large-scale quantities of FNWs and FNTs. These fullerene nanomaterials were synthesized by the liquid–liquid interfacial precipitation method using pyridine and isopropyl alcohol (IPA) as solvents. The C60–pyridine solution was illuminated using different wavelengths for 24 h at ambient pressure and temperature before addition of IPA. High yields (30–38 mg/L) were obtained upon irradiation using wavelengths in the ultraviolet region in accordance with the increased photoabsorption signal of solid C60 and C60 dissolved in pyridine acquired by a UV-VIS-NIR spectrophotometer. However, elevated yields (21–27 mg/L) were also obtained in the 600–800 nm regions, where C60 absorption is particularly weak. Such an enhanced yield of FNTs and FNWs is probably related to the reported rise in transient absorption of the triplet excited state of C60 in the 740 nm region formed by the decay of the photoexcited singlet C60 through intersystem crossing. The formation of photopolymerized fullerene nanofibers was also observed by Raman spectroscopy, it is attributed to ultraviolet and visible light irradiation. SEM and TEM observations suggest that preparation of FNWs and FNTs by irradiation using different wavelengths of light does not produce apparent morphological transformations on the surface of these fullerene materials.

        비지정문화재 보호의 모색 : 프랑스 법제와의 비교를 중심으로

        권채리 梨花女子大學校 法學硏究所 2016 法學論集 Vol.21 No.2

        우리가 흔히 논의하는 문화재가 ‘보호되는’ 문화재라면, 보호에서 소외된 즉 비보호문화재에 대한 고찰이 본 논문의 연구대상이다. 비보호문화재는 문자 그대로 보호되지 않는 문화재를 가리키나, 지정제도를 취하고 있는 한국에서는 이를 비지정문화재로 간주할 수 있을 것이다. 주지하다시피, 문화재는 역동적인 분야가 아니기에 일단 국가 또는 지방자치단체의 보호제도의 체계로 편입되면, 문화적 가치를 잃지 않는 한 공법인의 보호 아래 놓이게 된다. 그러나 특히 지방에는 국가나 지방자치단체의 관심에서 벗어난 상당한 수의 문화재가 존재한다. 프랑스에서는 이러한 문제점을 인식하여 ‘비보호 농촌문화재’(Patrimoine Rural Non-Protégé)의 보호를 목적으로 재단을 설립하고 예산을 배정하는 등 지정되지 않았으나 실질적으로 문화재적 가치를 지닌 기념물 및 건조물의 복원을 지원하고 있다. 이에 반해 우리나라에서는 비지정문화재로서 매장문화재, 일반동산문화재, 등록문화재를 규정하고 있으나 그 체계가 일관적이지 않다. 더욱이 동산 문화재는 그 이동성으로 말미암아 보다 정교한 규정이 요구됨에도 불구하고 현재 문화재보호법의 실정은 이를 뒷받침하지 못하고 있어 비지정문화재의 도난 내지 불법반출 등 많은 문제점이 제기되고 있다. 우리나라에서 비지정문화재에 관한 관심은 주로 ‘근현대’라는 시대성에 주목하여 나타나는 바, 2000년에 도입된 등록문화재를 비롯하여 근래에는 서울시의 미래유산, 그리고 예비문화재 등의 제도가 마련되었다. 본 연구에서는 보호대상인 문화재의 범위 및 보호를 위한 법적・행정적 수단을 프랑스와의 비교법적 관점에서 고찰한다. 비지정문화재에 대한 개입을 통해 문화재 보호의 외연을 넓히는 방안을 강구하는 것이 본 연구의 궁극적 목표이다. Recognizing that the term cultural heritage commonly refers to the historical assets that are “protected”, this study seeks to shed light on the unprotected heritages that linger in the legal apathetic. Unprotected cultural heritage denotes a social property that is literally unprotected, however, in Korea where the government has adopted the designation framework, the unpreserved assets may classify under the undesignated cultural heritages. A considerable number of cultural heritages in the regional province exist without legal protection. In this connection France, for instance, recognized the seriousness of this problem and showed their interests in the “Unprotected Rural Cultural Heritages” (Patrimoine Rural Non-Protégé) program, and supports the restoration of edifices that are not designated but pose a substantial cultural value through establishing foundations and allocating budget. On the other hand, the Korean framework of undesignated cultural properties do exist, which are buried cultural properties, registered cultural properties, and general movable cultural properties, but nevertheless it ails from its systematic inconsistency. Moreover, as the regulations on the import and export of general movable cultural properties are not as sophisticated as to our French counterparts, theft and illicit export now poses as a social problem. Understanding that the Korean interest on the undesignated cultural heritage mainly stems from the conceptual view of the “the modern age”, new classifications as the future heritages and Seoul preliminary cultural assets were introduced since the year 2000. This paper performs a comparative analysis on the legal and administrative measures to compare the scope regarding designation boundary of protected cultural heritages through comparative analysis on the aforementioned the French framework. The ultimate goal of this research is to develop methods to expand the scope of protection through some kind of intervention on the undesignated cultural assets.
