  • The objective of the study is to develop a GIS-based flood map. Hydraulic model (HEC-RAS) is linked with hydrologic model (HEC-HMS) for flood map. Geospatial data processors, HEC-GeoHMS and HEC-GeoRAS, are used for operating HEC-HMS and HEC-RAS. HEC-HMS was calibrated and validated at the Hwa-Ong watershed. HEC-HMS was used for calculating runoff from the Hwa-Ong watershed which consisted of Nam-Yang, Ja-An, U-Eun river sub-watersheds, and HEC-RAS was applied and validated for river flow routing at the Hwa-Ong watershed. The simulated results from HEC-HMS and HEC-RAS were reasonably good compared with the observed data. HEC-RAS and HEC-HMS were applied to simulate flooding from probability rainfall at the Hwa-Ong watershed, and the simulated result was used to develop a flood map. Flood map developed in this study will be used for mitigating and predicting the flood damages.

  • The objective of the study is to prepare input data for FIA (Flood Inundation Analysis) & FDA (Flood Damage Assessment) through rainfall-runoff simulation by HEC-HMS model. For HwaOng watershed (235.6 $km^{2}$), HEC-HMS was calibrated using 6 storm events. Geospatial data processors, HEC-GeoHMS is used for HEC-HMS basin input data. The parameters of rainfall loss rate and unit hydrograph are optimized from the observed data. HEC-HMS was applied to simulate rainfall-runoff relation to frequency storm at the HwaOng watershed. The results will be used for mitigating and predicting the flood damage after river routing and inundation propagation analysis through various flood scenarios.

  • Acquired Hallux varus is defined radiographically by a negative metatarsophalangeal angle and clinically by adduction of the hallux on the first metatarsal and most commonly occurs after hallux valgus surgery. It's the prevalence has ranged from 2% to 17%. We report a case of hallux varus resulted from weakening of support of lateral soft tissue and resection of an excessive amount of the metatarsal head during a bunionectomy after initial correction of hallux valgus. We corrected the hallux varus deformity using transfer of extensor hallucis brevis tendon with reconstruction os lateral capsule.

  • In the case of surface cracked plate specimen, we can not measure the fracture toughness of ductile materials by the ASTM E 813 standard method. In this report, using the Acoustic Emission method, we found out crack initiation point and investigated fracture toughness which was calculated by FEM. The method used in this paper shows that fracture toughnes by using AE technique is reliable.

  • The species diversity of Orchidaceae is believed to be extremely high in Myanmar. Like in other plant groups, little basic inventory work has been done thus far. During floristic surveys conducted in Popa Mountain Park (Mandalay Region), Natma Taung National Park (Chin State), and in the Ywangan area (southwestern Shan State), we encountered two interesting orchid species which were determined to be new generic records in the flora of Myanmar. Thuniopsis cleistogama was previously considered endemic to Yunnan Province (China) and was only known from the type locality. However, here the species is newly reported from two localities in central and western Myanmar. Disperis neilgherrensis is known from several widely scattered localities in tropical and subtropical Asia. This tiny orchid species was discovered in the Ywangan area in the southwestern area of the Shan State of Myanmar. These two species will be valuable additions to the updated checklist of the orchids of Myanmar.

  • Cellulitis is a infectious disease characterized by acute purulent inflammation clinically manifested by erythema, pain or heating sensation caused by palpation, chilling sign and mild to moderate fever. in western medicine most part of the treatment is focused on injecting routine antibiotics hoping for the pathogen(in the case bacteria) to be treated but instead causing the bacteria to be resistant to antibiotics and consequently leads to longer admission. In oriental medicine Cellulitis belongs to the cathegory of Ong(癰), Bal(發) or Dandok(丹毒) on symptoms. The chief cause of acute Cellulitis is the evil of wet and heat blended and the postraumatic infection evil. We experienced a case of acute cellulitis defined as Bicheonbal(비천발) and Chokbaebal(足背發). We attempted to use both methods using acupuncture, herbal medicine(Gamidangkwuijeomtong-tang(加味當歸拈痛湯)) as well as routine antibiotic treatment and as a result we have achieved remarkable results in laboratory tests though there was no difference in shortening the curing process compared to the average time that it take to cure when admitted to western medical center.

  • 이동 컴퓨팅 환경에서 이동 사용자는 무선 통신망의 협소한 대역폭을 효율적으로 사용하기 위하여 자주 데이타를 자신의 캐쉬에 저장하여 사용한다. 그러나, 이동호스트의 이동과 서버와의 통신 단절로 인하여 서버에 있는 데이타와 일관성이 위배되어 캐쉬된 데이타의 유용성이 상실될 수 있다. 기존 연구에서는 이동호스트의 캐쉬 일관성을 유지하기 위한 정책에 중점을 두었으며, 모든 이동 기지국에서 무효화 메시지를 방송하는 시점이 동일하다고 가정하였다. 본 논문에서는 이동호스트의 이동으로 인하여 발생될 수 있는 캐쉬 일관성 위배의 문제를 해결하는 캐쉬 일관성을 제안한다. 제안하는 정책은 각 이동 기지국이 무효화 메시지에 방송하는 메시지의 방송하는 시점을 다르게 함으로서 기존 정책에서 방송 시점을 일치시키기 위한 오버헤드를 줄일 수 있고, 이동 기지국이 이동호스트에게로 전송하는 메시지의 양을 줄일 수 있기 때문에 통신비용이 절감되고 무선 통신의 협소한 대역폭이 보다 효율적으로 사용될 수 있다.

  • 1. Objectives The pesent study purposed to examine Dongmu Lee Je-Ma's Sasang philosophy from the viewpoint of Che-Yong relation and to understand the effect of Che-Yong relation on Dongmu philosophy. 2. Methods First, we briefly compared the concept of Che-Yong relation in Jeongju philosophy, which has a dualistic philosophical structure, with the concept of Han Suk-Ji's harmonious Che-Yong relation, which has a monistic philosophical struaure and, based on rhe result, analyzed the characteristics of rhe concept of Che-Yong in Dongmu philosophy focused on Seongmyeong rheory, Sadan rheory and Hwakchung theory in ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3 Results and Conclusions Jeongju philosophy is different from Dongmu philosophy in irs philosophical struaure characterized by Che-Yong relation, and the concept of Che-Yong in Dongmu philosophy forms the characteristics of Han Suk-ji's monistic harmonious Ole- Y ong relation. This produces results as follows. (1) Form a universal view of human beings centering of man's autonomous will and possibility. (2) Have a philosophical structure understood nor as a partial thought but as a total thought. (3) Assert that man has a good nature fundamentally and is obliged to practice goodness. (4) Assume that all human beings are equal. (5) It is assumed that the structural characteristics of harmonious Che-Yong relation in Dongmu philosophy can be the ground of definition of Silhak (practical science) in Oriental philosophy. It can be said that the realities of the universe and human beings can be discussed in philosophical structure with the logic of harmonious Che-Yong relation based on the unity of time and space. The philosophical logic based on the tealities can be defined as Silhak.
