  • There have been various studies on measurements of flood risk and forecasting models. For river and dam region, PDF and FVI has been proposed for measurement of flood risk and regression models have been applied for forecasting model. For Bo region unlikely river or dam region, flood risk would unexpectedly increase due to outgoing water to keep water amount under the designated risk level even the drain system could hardly manage the water amount. GFI and general linear model was proposed for flood risk measurement and forecasting model. In this paper, FVI with the consideration of duration on GFI was proposed for flood risk measurement at Bo region. General linear model was applied to the empirical data from Bo region of Nadong river to derive the forecasting model of FVI at three different values of Base High Level, 2m, 2.5m and 3m. The significant predictor variables on the target variable, FVI were as follows: ground water level based on sea level with negative effect, difference between ground altitude of ground water and river level with negative effect, and difference between ground water level and river level after Bo water being filled with positive sign for quantitative variables. And for qualitative variable, effective soil depth and ground soil type were significant for FVI.

  • During a flood season, Bo region could be easily exposed to flood due to increase of ground water level and the water drain difficulty even the water amount of Bo can be managed. GFI for the flood risk is measured by mean depth to water during a dry season and minimum depth to water and tangent degree during a flood season. In this paper, a forecasting model of the target variable, GFI and predictors as differences of height between ground water and Bo water, distances from water resource, and soil characteristics are obtained for the dry season of 2012 and the flood season of 2012 with empirical data of Gangjungbo and Hamanbo. Obtained forecasting model would be used for keep the value of GFI below the maximum allowance for no flooding during flooding seasons with controlling the values of significant predictors.

  • East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

  • The purpose of this study is to investigate on the water quality of the upper region of Wonchun stream located in Suwon city by chemical analysis and EROD-microbioassay methods using rat hepatoma cell line H4IIE. The water samples were collected at 6 sampling sites from sept. to Nov. 1999 and determined the quantitative toxic effects. Higher levels of BO $D_{5}$, CO $D_{Cr}$ and CO $D_{Mn}$ were determined at M6 site where the influent contains domestic and industrial wastewater. EROD activity of water samples was ranged from 3.43$\pm$0.08 to 9.05$\pm$0.10 pmol/mg protein/min. High correlation with EROD activities and COD values was observed. From the results, the upper region of Wonchun stream water area was presumed to be highly polluted with various persistent organic chemicals.s.

  • Botulinum toxin type A (BoNT/A) has been proven to be a safe and effective treatment for wrinkles in human. As well as the anti-wrinkle effects, the anti-pruritic effect of BoNT/A has been revealed from several researches for new therapy. The aim of this study was to investigate the anti-pruritic effect of BoNT/A against histamine-induced pruritus on canine skin. Five clinically healthy beagles were included in the study. All dogs were received 0.05 ml (5 Unit) of BoNT/A on the right dorsal thoracic region as an experiment and the same volume of saline solution was injected on the left dorsal thoracic region as a control, respectively. Intradermal histamine injections were performed four times (before treatment and days 1, 3 and 7 after BoNT/A injection). The severity of pruritus, the diameter and thickness of wheal, the erythema index and cutaneous temperature were assessed. The severity of pruritus was reduced on BoNT/A treated sides, compared with saline treated sides (p < 0.05). BoNT/A decreased wheal size, in both diameter and thickness (p < 0.05). Although, erythema index of both sides were increased after first histamine injection, BoNT/A treated sides showed the low-value as compared with saline treated sides. Cutaneous temperature was decreased significantly on BoNT/A treated sides. These results indicates that BoNT/A reduce histamine-induced pruritus on canine skin and suggested a possibility of application of BoNT/A for local intractable dermatologic problem in dogs.

  • Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.

  • Botulinum neurotoxin (BoNT) injection for the treating plunged nose, post-rhinopasty and hyaluronic filler migration is common procedures in clinical settings. However, the lack of thorough anatomical understanding makes it difficult to locate the nose region muscles. The anatomical considerations concerned with BoNT injection into the nasalis, levator labii superioris alaeque, and depressor septi nasi muscles were reviewed in this study. The injection spots have been presented for the nasalis, levator labii superioris alaeque, and depressor septi nasi muscles, with the recommended injection technique for each muscle. We have suggested the ideal injection sites in association with outer anatomical landmarks of the nose region. Moreover, these proposals would support a more accurate procedure of BoNT injection in relieving plunged nose, preventing post-rhinoplasty deviation, and migration of the hyaluronic acid filler.

  • The electrochemical behavior of dissolved hydrogen (H2) was investigated at a Pt electrode in a high temperature LiOH-H3BO3 solution. The diffusion current of the H2 oxidation was proportional to the concentration of the dissolved H2 as well as the reciprocal of the temperature. In the polarization curve, a potential region in which the oxidation current decreases despite an increase in the applied potential between the H2 oxidation and the water oxidation regions was observed. This potential region was interpreted as being caused by the formation of a Pt oxide layer. Using the properties of the Cl- ion that reduces the growth rate of the Pt oxide layer, it was confirmed that there is a correlation between the Cl- ion concentration and the transient current of the H2 oxidation.
