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.

콘크리트 지하철 구조물의 비선형 지진응답해석

이종세,최준성,박균익 漢陽大學校 工學技術硏究所 2001 工學技術論文集 Vol.10 No.-

1995년 Hyogoken-Nanbu 지진은 RC 지중 지하철 구조물에 지난 과거 전혀 경험치 못했던 심각한 피해를 일으켰다. 이같은 지진피해의 정확한 평가를 위하여, 주파수영역상에서의 지반-구조물 상호작용효과를 고려한 지하 구조물에 대한 선형지진응답해석이 수행되어왔으나, 보다 정확한 지진피해를 예측하기 위해서는 시간영역상에서 지반과 구조물의 이력감쇠와 강성변화를 고려한 비선형지진응답해석을 수행하는 것이 반드시 필요하다. 본 논문에서는 지반-구조물 상호작용을 고려한 비선형 지진응답해석을 시간영역상에서 수행하기 위하여 주파수영역상에서 지반-구조물 상호작용효과를 고려하기위해 개발된 KIESSI-2D와 유한요소 범용해석프로그램 ANSYS를 연계한 복합법을 사용하여 Hyogoken-Nanbu 지진시 피해가 많았던 고베의 가미사와 지하철역을 대상으로 비선형 지진응답해석을 수행하고 실제 발생한 피해상황과 비교 ·분석하였다. 해석시 등가 선형화기법에 근거한 대표적인 자유장 해석프로그램인 SHAKE를 사용하여 지반의 비선형성을 고려하였고, 콘크리트의 비선형성을 고려하기위해서 Hognestad 모델을 사용하였다. 해석결과 실제 발생한 중간기둥의 전단파괴를 매우 유사하게 예측할 수 있음을 보여주었다. During the 1995 Hyogoken-Nanbu earthquake, underground RC structures experienced significant damages which had never been experienced before. To evaluate these damages, a linear earthquake response analysis in frequency domain has often been used. For more accurate evaluation of the damages, however, a nonlinear earthquake response analysis in time domain must be employed by incorporating she continuous change of stiffness and hysteresis damping of soil-structure interaction systems. In this study, a hybrid method which combines a soil-structure interaction program, KIESSI-2D with a general purpose FEM package, ANSYS is developed to perform nonlinear earthquake response analysis of soil-structure interaction in time domain. As a verification of the hybrid method, nonlinear earthquake response analyses are performed on the Kamisawa subway station which was damaged severely during the Kobe earthquake and analytical results are compared with the real damages. In order to consider the nonlinearity of soil, SHAKE program is used, whereas Hognestad model is used to consider the nonlinearity of concrete. It is shown that the analytical prediction agrees fairly well with the actual damages which were caused by the shear failure of the center column of the station.

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.

Rhyparini is one of the tribes of well-known termitophilous scarabs included in Aphodiinae Leach, 1815. Several species of the tribe are known to live in association with termites, with both organisms occurring together in relatively large numbers. In extant numbers of this tribe, the larvae live inside termite nests. The tribe Rhyparini can be distinguished by the following combination of characters: clypeus usually bidentate though sometime feebly so, inflexed edge medially obtusely angulate; frons and vertex with tufts of setae or longitudinal tubercles; pronotum with six longitudinal costae equally spaced in at least posterior half of disc, lateral pronotal edge at least feebly bilobed in anterior half; elytra costae, costae varying on height, number and spacing, elytral apices frequently bulbous, epipleura narrow; posterior prosternal process hastate; antenna 9th segmented, club 3th segmented, segments of club short and compact. The tribe includes 77 species of 12 genera worldwide, and Pittino (2006) published a key to world genera in the subfamily Rhyparinae (tribe Rhyparini). In total, nine species of two genera in the tribe Rhyparini have been recorded in the Palaearctic region up to date: Rhyparus Westwood with eight species and Sybacodes Fairmaire one species, In Japan three species are known, China with one and Taiwan five. However, up to date, any has not been reported in Korea. In the present study we report on the tribe Rhyparini from Korea for the first time, based on Rhyparus azumaiazumai Nakane, 1956. Diagnosis and illustrations of detailed diagnostic characters, including male genitalia are provided.

Subgenus Achlaenius Manldl, 1992 belonging to the genus Chlaenius Bonelli (1810) of the carabid tribe Chlaeniini. This subgenus was characterized by strong densely pubescent of pronotum and elytra. This subgenus was recorded five species in Korea and Paleoarctic region : Chlaenius micans Fabricius, 1792, C. ocreatus Bates, 1873, C. sericimicans Chaudior, 1876, C. variicornis Morawitz, 1863 and C. kurosawai Kasahara, 1986. However, subgenus Achlaenius was rarely studied in Korea until now because of similar morphological patterns and difficult identification with allied species. As the results, totally four speciesof this subgenus from Korea were reviewed photos of adult and genitalia in male, key to the species of subgenus Achlaenius from Korea

Myanmar, which has a total area of 678,500 square kilometers (262,000 sq mi), is the largest country in mainland Southeast Asia, and the 40th-largest in the world. It lies between latitudes 9° and 29°N, and longitudes 92° and 102°E. Much of the country lies between the Tropic of Cancer and the Equator. It lies in the monsoon region of Asia, with its coastal regions receiving over 5,000 mm (196.6 in) of rain annually. Annual rainfall in the delta region is approximately 2,500 mm (98.4 in), while average annual rainfall in the Dry Zone, which is located in central Myanmar, is less than 1,000 mm (39.4 in). The average annual temperature is about 27℃(about 80℉). This expedition was conducted two times in two years (8.7~8.17, 2011; 2.2~2.9, 2012). As protected forest from government, these areas were almost natural conservation field. Pitfall trap, sweeping method, light trap and searching etc. were used to collect insect. As the result, totally about 30 families in Coleoptera was collected, among them Oodes species of Carabidae was highest number and species in Chrysomelidae, Cicindelodae, Scarabaeidae and Dynastidae etc., were collected. It was difficult to identification because of lack of references of this areas. Maybe lots of new or new recorded species will discover from Myanmar. Among Coleoptera species, with big sized beetles as the central figure, photos for species of dominant, rare, nominated species of new or new recorded were introduced, and also collecting sites and activities were presented.

Ik Je CHOI,Jinyoung PARK,Bong Woo LEE,Shin Young PARK,Jong Kyun PARK 한국응용곤충학회 2014 한국응용곤충학회 학술대회논문집 Vol.2014 No.04

The present study was carried out to revise the species of Chlaeniini in Carabidae from South Korea, using both classic taxonomy and molecular analysis. Another aim is to decide the taxonomic position of Chlaenius micans Fabricius of which subgeneric status in the genus has been in question. As a part of the results, Chlaenius spathulifer Bates, 1873 was newly recognized to Korean insect fauna. With this new addition Korean Chlaeniini contains now in total 34 species and two genera. Molecular analyses using CO1 sequences of representative species for six subgenera in Chlaenius were conducted to determine the position of C. micans. The result of the analyses suggested that C. micans did not belong to the subgenus Achlaenius where C. micans had been doubtfully positioned despite distinct morphological differences from the other four species of the variicornis-group (C. sericimicans, C. variicornis, C. kurosawai and C. ocreatus) in the subgenus. This study provids a key to species, photos of adult habitus, photos of male genitalia and redescriptions of 28 Korean species in Chlaeniini.
