  • NCEP reanalysis data were analyzed in order to provide distribution of global wind resource and wind speed in the surface layer for the years 2000-2009. Wind speed at 10 m above ground level (AGL) was converted to wind speed at 80 m above the ground level using the power law. The global average 80 m wind speed shows a maximum value of $13ms^{-1}$ at the storm track region. High wind speed over the land exists in Tibet, Mongolia, Central North America, South Africa, Australia, and Argentina. Wind speed over the ocean increased with a large value in the South China Sea, Southeast Asia, East Sea of the Korea. Sea surface wind in Western Europe and Scandinavia are suitable for wind farm with a value of $7-8ms^{-1}$. Areas with great potential for wind farm are also found in Eastern and Western coastal region of North America. Sea surface wind in Southern Hemisphere shows larger values in the high latitude of South America, South Africa and Australia. The distribution of low-resolution reanalysis data represents general potential areas for wind power and can be used to provide information for high-resolution wind resource mapping.

  • This study is conducted to examine the solar radiation features of landscape in Eastern Mongolia and their space and time distribution characteristics. To many foreigners, the name Mongolia conjures up images of the vast steppes of Central Asia. And, indeed, the extensive grasslands of the steppe make up the heart of Mongolia-geographically and economically. Steppe covers nearly the entire far eastern part of Mongolia, extending west in a narrowing band just south of the Khangai and Khan Khokhii mountains all the way to the Depression of the Great lakes. Eastern Mongolia is recognized as one of the last remaining untouched grassland steppes in the world. Landscape of Eastern Mongolia divided by 19 types that belongs to High Mountain, Middle Mountain and low mountain steppe. Only 5.6% of the total land area is covered by forest. Eastern Mongolian steppe is homeland of migratory rare and endangered birds and about 2.0million freely migrating gazelles. According to Mongolian scientists, there is growing evidence of fundamental changes in the Eastern steppe ecosystems in terms of increasing aridity during the last 70 years. As estimated average annual temperature has increased by approximately 0.7oC, soil moisture, energy supply has been changing. These processes closely interrelated into water and energy cycle of steppe ecosystem.

  • The Republic of Kazakhstan is a geographically large but sparsely populated country, rich in natural resources, located in the center of the Eurasian continent. In recent years, it has begun to create a green economy, leading it among its neighbors in Central Asia. Therefore, the country has set a clear goal: by 2030, emissions should be reduced by 15-25% compared to the level of the 90s. As part of the country green economy strategy, in 2013 Kazakhstan adopted the "National Concept for the Transition to the Green Economy until 2050", which sets out the principles of the green economy as a path for future development. The goal is to bring the share of renewable energy in electricity production from zero to 3% by 2020, and then increase it to 30% by 2030 and 50% by 2050. This paper looks at what Kazakhstan has done to promote renewable energy and provider perspectives. The paper also considers Kazakhstani legislation in terms of the development of renewable energy sources and provides information on incentives and preferences for the development of renewable energy sources. Thus, it will be easier for investors to evaluate the implementation of potential projects in Kazakhstan.

  • Soy is an important food in Asia and many studies have suggested that the low incidences of chronic diseases in Asian countries are associated with diets that are rich in soy. Soy contains many kinds of phytochemicals, and soy isoflavones and soyasaponins have received considerable attention. Twelve isoflavone components have been isolated from soy: three aglycones (daidzein, genistein, and glycitein), and their respective nine glucosidic conjugates. Soy isoflavones are similar in structure to estrogen and exhibit both estrogenic and antiestrogenic activities. Soy isoflavones exhibit anticancer activity, can reduce the risk of cardiovascular disease, and are beneficial to brain and bone health. Soyasaponins are divided into three groups (A, B, and E saponins), and they exhibit hypocholesterolemic, anticancer, hepatoprotective, antioxidative, and anti-human-immunodeficiency-virus effects. Despite the abundant literature suggesting that soy isoflavones and soyasaponins have potential applications in preventive medicine, further research is needed to standardize dosages and ensure their efficacy.

  • The purpose of this research is to review historical development of Islamic finance in individual East Asian economies, including China, Japan, South Korea and Hong Kong, and examine the success factors of the Hong Kong Sukuk issuances in 2014-2017. The research is a qualitative study applying case study method. It is found that the East Asian economies do play efforts to develop their Islamic capital markets although they have very limited size of Muslim population. Their progress on this development generally remains to be slow. The Hong Kong Sukuk is a breakthrough, carrying a total issuance value of US$3 billion. The Sukuk issuances, treated as a kind of asset-backed securities with restrictions on financing purposes, are distributed to international investors by investment banks from Hong Kong, Middle East and Malaysia. Success factors of these issuances include involvement of an issuer with high credit quality, recognition by central bank for using the Sukuk in its discount facility for commercial banks, centralized clearing services for the Sukuk and global banking network for underwriting the Sukuk. The lessons from the Hong Kong Sukuk are good references for other economies to develop their regional Islamic capital markets and to integrate the markets into the global capital market.

  • The article studies the new situation in international long distance trade after the emergence of new superpower - Arab Caliphate - in Eurasian overland tracks of the Great Silk Road. The stages of Arab advancement along trade routes and outcomes of their contestation with the strong tribal confederations of Turkic nomads in Central Asia and the Caucasus are highlighted. A special focus is made upon the relationship of Arabs with Khazar Turks who have endured severe clashes with strongest army of the time in the region. Khazar kingdom survived and even expanded its control over the tracks of international trade in the western part of Eurasia. The research describes the way how trade partnership between Arabs and Turks was shaped in the aftermath of military clashes. Existing scholarly views on the role of Khazar in Silk Road are reviewed and unattended evidence of Arab sources are involved to support concluding points that Khazar state managed to consolidate various actors for maintenance of international trade such as so called Rus warriors and merchants in the west of Volga, nomadic tribes in Eurasian steppes, and Jewish trading gild named ar-rahdaniyya in Arab sources. It is asserted that Khazar state since the second half of 9th century through its decline in mid 10th century not only served as transit space for goods of exporting countries but also exported goods of its own crafts and natural resources.

  • History confirms that the eastern style was reflected in various parts of the western culture including clothing. In this paper we show some evidence that the influence of India on the French clothing during the neo-classical period(1789-1820) was substantial. Among others, the use of muslin, kashmir shawl and banyan during the period is greatly emphasized. The muslin imported from India was used as the textile for the chemise mown, a typical clothing during the period. Indian muslin was used, because it was of better quality compared to the muslin manufactured in England and France and it was not expensive. The kashmir shawl imported from kashmir in India was also a popular item in Europe not only because it matched well with simple color of chemise gown, but because it expressed the tone of Greek and Roman. Banyan which was most popular clothing worn by men in 18th century Europe originally came from India, which goes back to the Kaftan clothing in the Central Asia. Banyan was an informal home style clothing different from the conventional tight men's wear. It is true that the muslin, kashmir shawl, and banyan also became fashion items throughout the 19th and 20th century to the English and other European people. However, we limited our attention to the influence of India on France because we think the French Revolution and Napoleon's conquest of Egypt are far more important factors when considering the influence of Indian culture on Europe.

  • Rubus crataegifolius is a shrub species and is primarily distributed throughout Asia and Europe. We collected 550 representative samples of the eleven populations in Korea to estimate leaf variation within species. The 35 morphological characteristics allowed us to resolve well-supported fixed characteristics and variable characteristics. Sixteen of twenty-three quantitative characteristics and five of twelve qualitative characteristics showed significant differences among populations. We argued that the population differentiation can accounted for the variation in phenetic characteristics such as spine in this species, but were less successful in accounting for variation in other traits. Within a polystatistic leaf structure, their morphological differences could be modulated by ecological pressure such as temperature, altitude, duration of sunshine, and solar radiation. The phenogram showed two distinct clades. One was a group in central Korea and the other was a group in the southern regions of Korea. If morphological characteristics in R. crataegifolius populations reflect their ecological niche, morphology should be regarded with caution as the main criterion for population studies in R. crataegifolius.

  • The purpose of the present study was to provide an assessment of the incidence of cancer of the larynx in Kazakhstan with especial attention to ethnicity and gender, as well as age. The retrospective design covered all new cases of laryngeal cancer in 11 years (1999-2009). The total number was 4,967 cases, 4,535 (91.3%) in males and 432 (8.7%) in women, with a gender ratio of 10.5:1. Patients of Kazakh (31.2%) and Russian (51.4%) ethnicity accounted for the vast majority (82.6%), with Russians predominating in both sexes, but particularly in females. Age peak in Kazakhs was 70 years and older ($14.6{\pm}0.70/0000$), and in Russians was 60-69 years ($21.6{\pm}1.30/0000$). In the dynamics, the rates had the tendency to decrease more markedly in Russian than Kazakh men, especially in the younger groups, while increase was noted in the youngest females of both ethnicities, but again greater in Russians, presumably reflecting change in underlying lifestyle factors.

  • This research conducted a before/after naturalistic field experiment, with the early Arab Spring as the treatment. Compared to before the early Arab Spring, after the observation period the associations became stronger among the Web terms: 'Jihad, Sharia, innovation, democracy and civil society.' The Western concept of civil society transformed into a central Islamist ideological component. At another level, the inter-nation network based on Jihad-weighted Web hyperlinks between pairs of 46 Muslim Majority (MM) nations found Iran in one of the top two positions of flow betweenness centrality, a measure of network power, both before and after early Arab Spring. In contrast, Somalia, UAE, Egypt, Libya, and Sudan increased most in network flow betweenness centrality. The MM 'Jihad'-centric word co-occurrence network more than tripled in size, and the semantic structure more became entropic. This media "cloud" perhaps billowed as Islamist groups changed their material-level relationships and the corresponding media representations of Jihad among them changed after early Arab Spring. Future research could investigate various rival explanations for this naturalistic field experiment's findings.
