This paper is one of Korean towns in the period of Korean-Modern, which play an important role in shaping the present cities of Korea. In the concrete, this study deals with the urban form of the Japanese Concession at Womsan where is the second Open Port in Korea. By the way, both of the Open Port and the Concession were the town that not exist before the period of Korean-Modern, and the town that symbolize the historical characters of the period of Korean-Modern. On this study, it is intended to analyze the situations of establishment, the process of the urban form, and the meanings of Concession, from 1880 to 1910, the period when had been kept up the nature of the Concession mainly. The Japanese Concession at Wonsan was urged it's establishment by Japan Government that is conscious of the purpose of foreign trade and military importance. But, it was slow in progress of developing town because of the distance from the capital 'Han Yang', today we called it Seoul, and lack of the background towns. However, after both the wars of 1895 and 1904, Japanese residents were incresed and urban aspects were advanced. The urban form of Japanese Concession was devided two territories by the natural circumstances, so that was made a difference on the period of the development. And finally, it had double axis on the form of district. Furthermore, by increasing of residence, it was occured that new Japanese resident arwa was occupied and expanded illegally between the road which is toward the existing Korean village 'Womsan-Jin(元山津)'. This indeed is the illegal extension of the Japanese Concession at Wonsan. Conclusively, Concession fumed out the primary factor that Korean towns are altered with the heterogeneous ones in the period of Korean-Modern.

Pegmatite is a coarse-grained intrusive igneous rock rich in rare elements such as uranium, tungsten, and tantalum with Ca, K, Mg, Fe, Se, Ge, and Ho. We tested in vitro and in vivo assays for the anti-inflammatory activity of pegmatites. We firstly evaluated the suppressive effects of pegmatite on macrophage cell line RAW 264.7 cells stimulated with proinflammatory stimuli lipopolysaccharide (LPS) to determine nitric oxide (NO) production and TNF-$\alpha$ and IL-6 release. The $IC_{50}$ values of pegmatite exceeded $5,000\;{\mu}g/mL$. Treatment of RAW 264.7 cells with pegmatite significantly inhibited LPS-stimulated NO production and proinflammatory cytokines such as TNF-$\alpha$ and IL-6 secretion in a dose-dependent manner (P<0.05). In vivo studies were tested with two animal models of arachidonic acid-induced mouse ear edema and an acetic acid-induced increase in capillary permeability. The pegmatite significantly attenuated ear edema induced by arachidonic acid and reduced the acetic acid-induced increase in capillary permeability in mice (P<0.05) when the pegmatite was administered topically (10 mg per ear) for 24 h. Therefore, pegmatite potentially shows an anti-inflammatory activity in the in vitro and in vivo mice and in the development of newer anti-inflammatory agents as mineral materials.

The present study investigated the habitats of Korean fir trees (Abies koreana E. H. Wilson) on Mt. Baekwun (Baekwun-san), determined the current distribution, quantified the contribution of biological and nonbiological environmental factors affecting the distribution, derived actual and potential habitats, presented a plan for the establishment of protected areas, applied RCP 8.5 climate change scenario to analyze the effects of climate change on the future distribution of Korean fir trees, and predicted future potential habitats. According to the results of the study, 3,325 Korean fir trees (DBH >= 2.5 cm) inhabited Mt. Baekwun, and their distribution area was approximately 150 ha. Populations of Korean fir trees were confirmed to exist at an altitude of 900 m above sea level and were distributed up to 1,200 m. Based on potential distribution, areas appropriate for habitation by Korean fir trees were analyzed to be 450 ha, three times the current distribution area, with a focus on Sang Peak (Sang-bong), Eokbul Peak (Eokbul-bong), Ddari Peak (Ddari-bong), and Dosol Peak (Dosol-bong). The forest stands near Sang Peak, the main peak, were evaluated as those with the most appropriate potential for the habitation of Korean fir trees, and populations of the trees tended to prefer the northern slope rather than the southern slope. When climate change scenario RCP 8.5 was applied and future potential distribution was analyzed, the habitats were expected to decrease in area to 20 ha by 2050, with a focus on Sang Peak, and areas appropriate for habitation were predicted not to exist by 2080. Judging from such results, as global warming accelerates, the habitats of Korean fir trees are clearly expected to move from lowlands to highlands.

The weld scallop has been used for joining T-bars. There are a lot of weld scallops in shipbuilding. It is difficult to perform scallop welding due to the inconvenient welding position. This results in many problems such as porosity, slag inclusion, etc. In this study, a new method is devised to remove weld scallops by incorporating a Ceramic Backing Material (CBM). The weld scallop is removed by an elongation of the v groove. In order to insert a CBM into the groove without a weld scallop, a wedge-shaped CBM is developed. The top side of the developed CBM is similar to the shape of a general back bead. The bottom surface has a saw-toothed shape for cutting at a suitable length. This can be attached to the root side of a face plate using adhesive tape, just like a general CBM. Welding experiments in normal and abnormal conditions are carried out and the possibility of burn-through is examined. This CBM"s applicability to shipbuilding is verified.

<P>The thalamocingulate tract between the anterior thalamic nuclei and the cingulate gyrus is a part of the Papez circuit. Using diffusion tensor tractography, injury of the thalamocingulate tract was investigated in patients with mild traumatic brain injury. Two patients (patient 1: a 58-yr-old woman and patient 2: a 49-yr-old man) with head trauma resulting from a car accident were enrolled. They were classified as mild traumatic brain injury and no specific lesion was observed on brain magnetic resonance imaging. These patients complained of memory impairment after head trauma. The entire Papez circuits, including thalamocingulate tract, fornix, mammillothalamic tract, and cingulum, were reconstructed in both hemispheres except for the left thalamocingulate tract: patient 1, it was thinner and discontinued compared with the right thalamocingulate tract; and patient 2, it was not reconstructed. The injury of the left thalamocingulate tract appeared to be related to the memory impairment in these patients.</P>

The C-repeat/dehydration-responsive element binding transcription factors (CBF/DREBs) are involved in an important pathway for abiotic stress-response in plants. We have identified CBF/DREB1 gene family from Brassica rapa whole genome sequence and designated them as BrDREB1s. They contain conserved nucleus localization signal, AP2/EREBP domain, and CBF/DREB1 signature, as other known plant CBF/DREB1s. By comparative genomics, we found that nine of ten BrDREB1 genes were present in seven macro-synteny blocks co-linear to four Arabidopsis counterpart blocks and also genomic organizations of their flanking regions were very similar to those for co-linear Arabidopsis CBF/DREB1 genes. In particular, three genes, BrDREB1A, BrDREB1B1, and BrDREB1C1, were closely located within a 59 kb genomic sequence, which was similar to that of their Arabidopsis counterpart genes. However, the genomic regions of those BrDREB1 genes contained additional sequences, compared to their co-linear regions in A. thaliana. The expression of BrDREB1 genes under abiotic stresses were examined by searching microarray database and by RT-PCR analysis. All of eight genes tested were highly up-regulated during cold treatment and some of them were also responsive to salt, drought, and ABA treatment. Taken together, these results indicate that CBF/DREB1-mediated stress signaling pathway is also functioning in B. rapa. On the other hand, differences in genomic organization and gene number for CBF/DREB1 are thought to cause different response to stress between B. rapa and A. thaliana. In this presentation, we will introduce more detailed results for CBF/DREB1 gene family in B. rapa.
