The biodiversity of wetland ecosystems has received scant attention in Mongolia. We measured amphibian and macroinvertebrate species diversity at a complicated land-water ecotone of a pond within a wetland complex in Shaamar during July 2005. From our study area (0.5-ha grassland and an adjacent pond), we sampled 4,926 animals including 1 mammal, 4 amphibian, and 26 aquatic macroinvertebrate (>2 mm) species with a biomass of 4,444 g. Among these, a backswimmer (Notonectidae sp. 1) was a dominant species, representing 65% of the total number of animals collected (3,209) and 22% of the mass (999 g). Our study area was small but contained 4 amphibian species (Hyla japonica, Rana amurensis, Bufo raddei, and Salamandrella keyserlingii) in a mixed community with Shannon Diversity Index (H′) of 1.678 and Pielou's Evenness Index (J′) of 1.211. No larvae or tadpoles of any amphibian species were found in the pond, indicating their early metamorphosis. H′ and J′ with 26 macroinvertebrate species were estimated to be 1.828 and 0.561, respectively. This suggests that low macroinvertebrate species diversity relative to high species richness is due to low evenness resulting from considerable numbers of a backswimmer. In 6 sites sampled in the pond, mean water pH revealed high alkalinity (range 9.01-10.45). The presence of our taxa in a highly alkaline environment indicates that they may be alkaliphilic. © 2010 The Japanese Society of Limnology. Source

The competitiveness of a service organization is expressed through service quality (Lewis 1989). Good quality services or high client satisfaction is very important to contemporary service organizations (hung 2003). The service quality is important both for public and private businesses and service sectors (Zahari 2008). Therefore, we used SERVQUAL model in our study which looks at the gap between the expectations of the trainees or clients and the perception of actual services they received in order to define and evaluate quality. As the higher education system is rapidly developing in the increasingly globalized world, The universities of highly developed countries like European Union, US, Japan and even China, South Africa, Malaysia, Greece and Iran, are using SERVQUAL model to evaluate their training service quality. Therefore, the purpose of our research was to evaluate quality of training ser vices provided by public nursing schools using SERVQUAL (Model of Service Quality), which is widely used throughout the world. The survey was conducted using random sampling among 545 students studying in 4 urban and rural nursing schools or medical colleges in 2011. all indicators of SERVQUAL model showed in overall negative gap results and the lowest gap result or the least scored dimensions of service quality was empathy(-0.07) and tangibles (-0.08). Total service quality was (0.10) or posi tive. there was a significant gap (p < 0.001) between the students' expectations and perceptions in all five indicators of SERVQUAL. The needs and socio-economic status of students enrolled in the nursing schools differ widely depending on the location, whether it is the capital city or rural areas. That is why the expectations of nursing students are different which leads to diverse and contrasting perception gaps on the services they receiver service quality. © Borgis. Source

The first (M1) and the second (M2) Zagreb indices, as well as the first (M̄1) and the second (M̄2) Zagreb coindices, and the relations between them are examined. An upper bound on M1(T) and a lower bound on 2M2(T) + 1/2M1(T) of trees is obtained, in terms of the number of vertices (n) and maximum degree (Δ). Moreover, we compare the Zagreb indices and the Zagreb coindices of trees. Source

The aim of this study is to conduct urban mapping and analyze the land use changes of Ulaanbaatar city, Mongolia using very high resolution remote sensing (RS) and geographical information system (GIS) data sets. For the study, the changes that occurred before 1990 are compared with the changes that occurred after 1990 and the socio-economic reasons for the changes are described. For the development of the primary digital database, a large scale topographic map and historical description of the land use elements are used. To generate land use information from the fused RS images, a visual interpretation is applied. Overall, the study demonstrates that during the market economy the central part of the capital city is urbanized very rapidly and became very dense.

The aim of this study is to investigate the city management in Ulaanbaatar, specifically in the district-13 area, using modern game theory and a GIS. Initially, a primary digital database is developed using available (spatial and attribute) data sets, and then updated through processing of a very high resolution satellite image. Applying "The Tragedy of the Commons" framework we have found that the private incentives among the construction companies drove the supply of apartments higher. We estimated that if the construction companies cooperated instead of competed with each other, it would have been socially optimal. Source
