Myanmar is located in the south-east Asia peninsular and it is flanked by five neighboring states: Bangladesh, India, China, Laos and Thailand. It is located 10~22 degree north latitude, to 92~101 degrees east longitude. Myanmar has a tropical climate with three seasons in Myanmar. Hot season (March through April), rainy season (May through October) and the cool season (November through February). The coastal regions can get very hot and humid, especially before the rainy season. Myanmar has a monsoon season from May to October when there are heavy rains and often flooding. The investigation was carried out during the dry season(2013) in Nat Ma Taung National Park and Popa Mountain Park. Popa Mountain Park is located in Kyawpadaung Township, Myinchan district, Mandaly Division. The area is 49.63 square miles. Its coordinates are 29°31'60" N and 27°43'60" E. Nat Ma Taung National Park, Myanmar treasure is in Mindut District of Chin State and its area of 279 square miles. It is the third highest mountain in Myanmar with the height of 10,500 feet. Its coordinates are 21°14'00" N and 93°54'00" E. As the result, butterflies(Lepidoptera) collected in the two regions were about 60 species of 7 familys. Collecting dates, expedition activities, photo of main specimen and information of Myanmar were provided.

Kyoung In Yun,Min-Kyu Park,Myung-Kyun Park,Je Uk Park 대한구강악안면외과학회 2012 대한구강악안면외과학회지 Vol.38 No.6

Objectives: This study sought to evaluate fixation methods and determine the best method for the postoperative stabilization of maxillary osteotomy. For our analysis we performed a three-dimensional finite element analysis of stress distribution on the plate, screw, and surrounding bone, as well as displacement onto the plate. Materials and Methods: We generated a model using synthetic skull scan data; an initital surface model was changed to a solid model using software. Modified anterior segmental osteotomy (using Park’s method) was made using the program, and four different types of fixation methods were used. An anterior load of 100 N was applied on the palatal surface of two central incisors. Results: The Type 1 (L-shaped) fixation method gave stresses of 187.8 MPa at the plate, 45.8 MPa at the screw, and 15.4 MPa at the bone around the plate. The Type 2 (I-shaped) fixation method gave stresses of 186.6 MPa at the plate, 75.7 MPa at the screw, and 13.8 MPa at the bone around the plate. The Type 3 (inverted L-shaped) fixation method gave stresses of 28.6 MPa at the plate, 29.9 MPa at the screw, and 15.3 MPa at the bone around the plate. The Type 4 (I-shaped) fixation method gave stresses of 34.8 MPa at the plate, 36.9 MPa at the screw, and 14.9 MPa at the bone around the plate. The deflection of the plates for the four fixation methods was 0.014 mm, 0.022 mm, 0.017 mm, and 0.018 mm, respectively. Conclusion: The Type 3 (inverted L-shaped) fixation method offers more stability than the other fixation methods. We therefore recommend this method for the postoperative stabilization of maxillary osteotomy.

An amperometric biosensor has several advantages such as, among others, low production cost, simple measurement scheme over other types of biosensor. Up until now, research activities in amperometric biosensors have mainly been focused on the liquid-phase analysis. However, efforts are required to be directed towards newly developing the capability of analyzing gas-phase samples for wide and extensive applications of amperometric biosensors. In this work, we have successfully fabricated a thick-film amperometric biosensor with the capability of effectively and sensitively sensing ethanol vapor, demonstrating that even gas-phase sample can be effectively detected using a simple amperometric biosensor.

We have examined the relaxational reponse to the water extract of Angelica gigas Nakai (AG), A. sinensis(Oliv.) Diels (AS), A. acutiloba Kitagawa (AA), and Four-Substance Decoctions (AG-FSD, AS-FSD, AA-FSD) in isolated thoracic aorta from sprague dawley(SD) rat in the presence and absence of endothelium. Rat thoracic aorta was investigated in vessel segments suspended for isometric tension recording by polygraph. Responses to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD were investigated in vessels precontracted with 5-hydroxytryptamine(5-HT) were compared in vasodilation effect. We found that the thoracic aorta segments responded to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD with a dose-dependent vasodilation. The 5-hydroxytryptamine induced contraction at 10-4M were inhibited by 26.3%, 2.7%, 2.1% and 24.6%, 1.1%, 3.2% after addition of the 0.1 g/㎖ water extract of AG, AS, AA and AG-FSD, AS-FSD, AA-FSD. The 5-hydroxytrptamine induced contraction at 10^-4M with and without endothelium were inhibited by 24.6% and 6.9% after addition of the 0.1 g/㎖ water extract of AG-FSD. In conclusion, AG, AS, AA and AG-FSD, AS-FSD, AA-FSD-induced relaxation in the isolated rat thoracic aorta were composed of dose-dependent relaxation. AG-FSD has very potent vasodilation.

이강신,김태한,김승렬,신민철,이원용,박제균 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1

Interdigitated array (IDA) electrodes were fabricated using silicon technology for highly sensitive biosensing. Thin-film platinum and gold IDA electrodes were fabricated with 10 μm band width and 7 μm gap between the bands using photolithographic techniques. The IDA electrode has 100 fingers consisting of 50 finger anodes and 50 finger cathodes. By applying both the oxidation and the reduction potentials of a reversible redox couple, ferrocyanide, to the pairs of the IDA electrode, an increased current generation can be observed. In our experiment, the collection efficiency of IDA electrode was 46% and amplification factor was 12.6. This preliminary experiment implies that the IDA electrode could be applied to biosensor fabrications as the sensitive electrochemical transducer when a lower detection limit is needed such as phenol sensor for drinking water analysis.

Myanmar is located in the Southeastern region of Asia. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. The bordering countries are China on the northern side, Thailand and Laos on the eastern region, Bangladesh on the western side and India on the northwestern region. Myanmar has a total area of 678,500 square kilometers (262,000 sq mi). The rainy season exists primarily during the months between June and September. Whiledry season stays during the months between December and April. Northern regions of the country are the coolest, with average temperatures of 21 ℃ (70 ℉). Coastal and delta regions have an average temperature of 32 ℃ (86.9 ℉). This expedition was conducted four times for three years. Among them we explored three area including Popa Mountain, Alaungdaw Kathapa National Park and Nat Ma Taung National Park[Popa Mountain(8.7~8.17, 2011; 7.24~8.3 2012; 2.18~2.28 2013), Alaungdaw Kathapa National Park(2.2~2.9, 2012) and Nat Ma Taung National Park(2.18~2.28 2013)]. Collecting methods was sweeping net, lignt trap, burket trap, pitfall trap with other method, and collected especially mainly Coleoptera and Lepidoptera. As the result, totally about 30 families in Coleoptera and 7 families in Lepidoptera were collected, among them Carabidae and Nymphalidae was revealed most diversity species. Main collect specimens, expedition activities and collections data etc. were provided herein.
