  • Jang Hyeongwang is one of the leading scholars since the era of Toe'gye and Yulgok in Korean Confucianism. Thus, this paper will summarize his schooling, i.e., education in local school(Hyanggyo), specific activities, and the meaning of moral education. Although Toe'gye and Yulgok recognized the problems of local school and their indictment revealed in 16th century, they sought different solutions to overcome the issues. Toe'gye paid attention to establishment of local academy(Seowon) and strengthening its stature in order to renew Confucian education while Yulgok kept an eye on reformation of local school as government educational institution for revitalizing schooling, fostering the talented and establishing moral discipline. In this context, I will summarize Yeoheon's perspective on schooling in terms of the difference with Toe'gye and Yulgok's ideas. Especially, I will analyze his problematique paying attention to restoration of moral order in local communities devastated since Japanese Invasion of Korea in 1592, and how it makes connection with local education and its implication. Furthermore, I will systematically examine the educational regulation of Indong local school(Indong Hyanggyo) he proposed and what its contents and real body he intended. In addition to these, I will suggest how much Yeohon's ideas on local education are meaningful in moral education and what kind of insightful things they would give us in current educational environments.

  • Purpose: Angiosarcoma of the scalp is unusual vascular tumor originating from endothelial cell. Angiosarcoma is an aggressive tumor with high propensity for both local recurrence and distant metastasis. We report 2 cases of angiosarcoma having poor prognosis recently. Methods: Case 1 was a 67 - year - old male patient. He visited the hospital with a $3{\times}5cm$ sized discolored mass in forehead. It began at one month ago from coming to the hospital. Case 2 was a 64 - year - old male patient. He visited for our hospital to remove a $4{\times}5cm$ sized scalp mass. He had a pruritis on scalp from 9 months ago before coming to the hospital. Despite of the conservative treatments, the wound was not healed and advanced necrotic lesion with hemorrhage. Results: Case 1 diagnosed as an angiosarcoma. He underwent a radical operation 5 times. But the tumor expanded multiple area in dura & frontal area of the brain. The patient rejected the treatment any more. And he died one month later. Case 2 diagnosed as an angiosarcoma and metastased to skull in MRI. He got a radical resection including cranium. Three months later, it recurred to ipsilateral Sternocleidomastoideus muscle. He got a additional operation & started radiotherapy. And now he is receiving chemotherapy, but the recurred lesion is expanding. Conclusion: Angiosarcoma is a highly malignant tumor. Especially it arises in vascularized area, it easily metastases. So it is the best to treat angiosarcoma with surgery included wide margins. Despite of the lesion is small, we remember that angiosarcoma is a tumor that consider to metastases.

  • We report a case of intracranial dissemination developing approximately 4 months after partial removal of a spinal cord anplastic astrocytoma in a 22-year-old male. He presented with paraplegia on initial admission at a local hospital. Spinal magnetic resonance (MR) images disclosed multiple intramedullary lesions at the T3-11. The tumor was partially removed. The final histologic diagnosis was anaplastic astrocytoma. Four months after the operation, he was admitted with the symptoms of headache and deterioration of consciousness. MR images showed enhanced lesions in the anterior horn of the left lateral ventricle, and septum pellucidum. He underwent computed tomography-guided stereotactic biopsy and histological appearance was consistent with anaplastic astrocytoma. The clinical course indicates that the tumor originated in the spinal cord and extended into the subarachnoid space, first the spinal canal and later intracranial.

  • We report a 18-year-old man, who has been taking antihypertensive medication for 1month in a local clinic, presented with a sudden onset headache followed by left blindness. He experienced palpitation and chest discomfort during physical exertion since 2years before admission, but unfortunately has been ignored. Brain CT showed intracerebral hemorrhage in the left temporoparietal area, but cerebral angiogram and magnetic resonance image revealed no vascular anomaly. He was managed conservatively, and headache and visual loss were improved over time. Subsequently, on the evaluation of hypertension, he was diagnosed as having extra-adrenal pheochromocytoma on left paraaortic area from the results of endocrinological evaluations, abdominal CT scan, and $^{131}I$-MIBG scintigraphy.

  • Objective: At least eight local duck breeds have been recognized and documented as national germplasm of Indonesia so far. It is necessary to genetically characterize the local duck breeds for aiding conservation and future improvement strategies. Thus, this study was carried out to assess genetic diversity and phylogenetic relationship of eight local duck populations of Indonesia using microsatellite markers. Methods: In total, 240 individuals (30 individuals each population) from Alabio (AL), Bayang (BY), Magelang (MG), Mojosari (MJ), Pegagan (PG), Pitalah (PT), Rambon (RM), and Turi (TR) duck populations were genotyped using 22 microsatellite markers. Results: The results showed a moderate level of genetic diversity among populations, with a total of 153 alleles detected over all loci and populations, ranging from 3 to 22 alleles per locus. Observed (Ho) and expected heterozygosity (He), as well as polymorphism information content over all loci and populations were 0.440, 0.566, and 0.513, respectively. Heterozygote deficiency in the overall populations ($F_{IT}=0.237$), was partly due to the heterozygote deficiency within populations ($F_{IS}=0.114$) and moderate level of genetic differentiation among populations ($F_{ST}=0.137$). The most diverse population was MG (He = 0.545) and the least diverse population was AL (He = 0.368). The majority of populations were relatively in heterozygote deficiency (except AL), due to inbreeding. The genetic distances, phylogenetic trees, and principal coordinates analysis concluded that the populations can be grouped into two major clusters, resulting AL, MG, and MJ in one cluster separated from the remaining populations. Conclusion: The present study revealed a considerable genetic diversity of studied populations and thus, proper management strategies should be applied to preserve genetic diversity and prevent loss of alleles.

  • Flange and web local buckling in beam plastic hinge regions of steel moment frames can prevent beam-column connections from achieving adequate plastic rotations under earthquake-induced forces. This threat is especially valid for existing steel moment frame buildings with beams that lack adequate flange/web slenderness ratios. As the use of fiber reinforced polymers (FRP) have increased in strengthening and repair of steel members in recent years, using FRPs in stabilizing local instabilities have also attracted attention. Previous computational studies have shown that longitudinally oriented glass FRP (GFRP) strips may serve to moderately brace beam flanges against the occurrence of local buckling during plastic hinging. An experimental study was conducted at Izmir Institute of Technology investigating the effects of GFRP reinforcement on local buckling behavior of existing steel I-beams with flange slenderness ratios (FSR) exceeding the slenderness limits set forth in current seismic design specifications and modified by a bottom flange triangular welded haunch. Four European HE400AA steel beams with a depth/width ratio of 1.26 and FSR of 11.4 were cyclically loaded up to 4% rotation in a cantilever beam test set-up. Both bare beams and beams with GFRP sheets were tested in order to investigate the contribution of GFRP sheets in mitigating local flange buckling. Different configurations of GFRP sheets were considered. The tests have shown that GFRP reinforcement can moderately mitigate inelastic flange local buckling.

  • Named Entity Recognition (NER) is always limited by its lower recall resulting from the asymmetric data distribution where the NONE class dominates the entity classes. This paper presents an approach that exploits non-local information to improve the NER recall. Several kinds of non-local features encoding entity token occurrence, entity boundary and entity class are explored under Conditional Random Fields (CRFs) framework. Experiments on SIGHAN 2006 MSRA (CityU) corpus indicate that non-local features can effectively enhance the recall of the state-of-the-art NER systems. Incorporating the non-local features into the NER systems using local features alone, our best system achieves a 23.56% (25.26%) relative error reduction on the recall and 17.10% (11.36%) relative error reduction on the F1 score; the improved F1 score 89.38% (90.09%) is significantly superior to the best NER system with F1 of 86.51% (89.03%) participated in the closed track.

  • We have identified local analogs of strong $H{\alpha}$ Emitters (HAEs) that dominate the z~4 Lyman-break galaxy population using the Sloan Digital Sky Survey (SDSS). At z<0.4, only 0.04% of galaxies are classified as HAEs with $H{\alpha}$ equivalent width larger than $500{\AA}$, comparable to that of z~4 HAEs. The $H{\alpha}$-to-UV luminosity ratio of local HAEs is consistent with that of z~4 HAEs, indicating relatively large specific star formation rate in these galaxies compared to traditionally studied UV-selected Lyman break analogs. Local HAEs are young, less evolved galaxies with low metallicity. It is still difficult to constrain whether the star formation in local HAEs is powered by minor mergers or by cosmological cold gas accretion. However, the stacked optical spectrum of local HAEs shows several strong ionization lines, for example HeII 4686 emission line, which are shown in Wolf-Rayet galaxies. Thus it is highly likely that local HAEs are galaxies with an elevated ionization parameter, either due to a high electron density or large escape fraction of hydrogen ionizing photons.
