<B>Purpose: </B>PET-CT is often used to differentiate benign or malignant thyroid incidentalomas. In this retrospective study, we evaluated whether the <SUP>18</SUP>F-FDG uptake pattern and PET-CT findings improved accuracy over the standardized uptake value (SUV). <B>Methods:</B> <SUP>18</SUP>F-FDG PET-CT was performed on 2,178 subjects from August, 2004, to October, 2007, in Sung-ae Hospital. PET-CT was performed on 806 patients (37%) with suspected or known nonthyroidal cancer and 1,372 healthy subjects (63%) without a previous history of cancer. We investigated the clinical characteristics of patients, history, standardized uptake value (SUV), ultrasonography, and hormone levels in blood. Thyroidal cancer was confirmed by ultrasonography-guided fine needle aspiration and pathology after thyroid operation. <B>Results:</B> The prevalence of focal thyroid lesions on PET-CT was 8.8% (191/2178). Thyroid cancer confirmation was 7.9% (15/191). The maximum SUV of malignant thyroid lesions were significantly higher than that of benign lesions (7.00±3.08 vs. 4.49±1.84, P<0.001). <B>Conclusion:</B> PET-CT image interpretation that includes 18F-FDG uptake and SUV is better than PET-CT alone for differentiating benign and malignant lesions. Thyroid cancer risk increases as SUVmax levels increase. <B>(Ko</B><B></B><B>rean J Endocrine Surg 2008;8:38-42)</B>

These studies were carried out to know the variation of needle characteristics of Abies Koreana distributed in Korea. The results are summarized as follows. The differences of needle length and number of stomata row among the population were shown one percent level but not in each individual tree. Correlations coefficients between the D.B.H. and needle length or needle width of mother trees were not correlated all populations respectively. It was found that correlation coefficient between needle length and needle width was positive in two populations. of Mt. Doukyou and Mt. Hanla, but it was not in Mt Jiri. Correlation coefficient between needle length and the number of stomata row positive correlation in Mt. Doukyou. Correlation coefficient between needly width and the number of stomata row was shown positive in all populations, but it was not that correlation coefficient between needle width and density of serrations, and between number of stomata row and density of serrations. The coefficients of variations were shown higher density of serration than needle length, needle width and stomata row.

Experiments were carried out to find the difference of resin canal numbers by tree age and topophysis of crown of black pine needles, and the results were summarized as follows. 1. The average numbers of resin canal by tree age were increased from the age of 5 years were not difference between 10 and thereafter years significantly. 2. In this observation, the range of resin canal number was 2 to 9. 3. The numbers by the topophysis of crown did not show significant differences but the individual trees showed significant variations in the canal number in younger trees.
Another EIL: Teaching English as an Intercultural Language (EIcL)
이강영 서울대학교 언어교육원 2013 語學硏究 Vol.49 No.2
The objective of this paper’s investigation is to address what “English as an intercultural language (EIcL)” is and why EIcL needs to be highlighted as a contemporary pedagogic movement of EIL, and then identify what is needed to teach EIcL. This is to claim that EIcL functions to be a contextual factor facilitating success in getting competency/proficiency among the wide variety of Englishes. For this, the paper first delves into the importance of EIcL and some essential features of EIcL. Then it moves on to delineate the core components of EIcL to teach;thus, readers of this article such as the contemporary ELT teachers along with SLA researchers, not to mention ELT examination boards,can benefit.
