  • A study was designed to investigate the effectiveness of Korean Red Ginseng (ERG) as an oral agent for erectile dysfunction (EF), which was compared to that of placebo and trazodone. Patients who were believed to have EF of mild or non-organic etiologies, randomized into 3 groups to receive 600 mg KRG 3 times daily (group A), placebo (group B) and 25mg trazodone once a day after evening (group C). All agents were given orally. Ninety patients, composed of 30 in each group, were included and analyzed only when clinical follow-up could be achieved at the end of the study for at least 3 months. There were no significant differences(p>0.05) between each group in mean age (43.7 years), duration of EF (5.8 years), the state of marriage (married : 80 patients) and duration of marriage (18.2 years). In group A, the parameters such as rigidity and tumescence on erection, early detumescence, libido and patient's satisfaction were significantly more effective than that of other group (p<0.05). But there were no significant differences in the parameters such as the frequency of coitus, premature ejaculation and morning erection between 3 groups (p>0.05). The efficacy achieved with KGR (60%) was significantly higher (p<0.05) than that of placebo (30%) and trazodone (30%). There were no significant changes on level of serum testosterone and type of AVS-penogram in group A. No side effect was demonstrated in all patients.

  • The actuators of anti-vibration system(AVS) can be separated into several types: piezoelectric actuators, pneumatic springs, cylinders, rotating motor and linear motor. The last one has some advantages, such as low noise, low vibration, simpler configuration and possibility of direct drive. The voice coil motor(VCM) is one type of linear motor, originally used in speaker system. VCM actuators are usually used in occasions that rapid and controlled motion of devices are required. In this paper, a controller which satisfies system specification(e.g. current controller bandwidth) within whole operation range is designed. For that objective, parameters as position were initially obtained with 3D FEM analysis and motor modeling was performed. A current controller in 2-axis VCM drive system was designed and then performance of the proposed controller was verified with simulation using Simplorer and an experimental result.

  • This paper deals with the question of the origin of polo. Although it is a sport that has been mainly active in the West since the nineteenthcentury, it is well known that British troops in the northern part of Pakistan learned about the sport from the local people there. Most agree that the origin of polo is Iran. However, in this paper, rather than specifying a specific area as the birthplace of polo, it is argued that polo was a cultural phenomenon commonly found on the Silk Road. This is based on the fact that polo has been known for centuries in China, the Korean Peninsula, and Japan, as well as throughout Iran, northern India, Tibet, Central Asia, and the Uighur Autonomous Region. Yet, the transmission of polo cannot be traced chronologically according to the supposed propagation route. This cultural phenomenon has changed over a long period of time according to the local environment, and the change was caused by mutual exchanges, not by one party. Therefore, there are limitations to interpreting cultural phenomena linearly. Thus, the origin of polo could also be identified with another area, namely Baltistan in modern day Pakistan, instead of Iran. These results support the argument that to understand Silk Road civilization, a process-centric approach based on 'exchanges', not a method of exploring archetypes to find 'the place of origin', should be utilized. Polo is undoubtedly an important cultural artifact with which to read the Silk Road as a cultural belt complex, as well as an example of the common culture created by the whole Silk Road.

  • Bloody wars between Arab Muslims and Khazar Turks in the Caucasus continued for a more than a hundred years from the mid $7^{th}$ century to the end of the $8^{th}$ century CE. The Khazar state survived but had to withdraw from Caucasian Albania, the present territory of the Republic of Azerbaijan. However, the Khazars managed to expand their political control over the trade routes north-east and north-west of the Caucasian ridge. A trade partnership was established between former rival powers in the region that allows us to call the period after the end of the Arab-Khazar wars up to the time of the collapse of the Khazar state in the middle of the 10th century an era of Arab-Khazar partnership and domination of the Silk Road. This article highlights the impact made by geopolitical shifts in the regions of the time upon international trade tracks and particularly on the development of trade facilities, infrastructure, and local production in Azerbaijan, which became a major transit country of goods from the north to markets in the Muslim Near East.

  • The Silk Road usually implies a network of trade and communications that stretched from east to west and connected China and the countries of the Far East via Central Asia and the Middle East to the eastern Mediterranean, or through the northern coast of the Caspian Sea and the Volga basin to the Black Sea coast. However, at certain historical stages, a network of maritime and overland routes stretching from north to south, commonly called the Volga-Caspian trade route, also played a significant role in international trade and cultural contacts. The geopolitical realities of the early Middle Ages relating to the relationship of Byzantium, the Sassanid Empire, and the West Turkic Khaganate, the advance of the Arab Caliphate to the north, the spread of Islam in the Volga region, the glories and fall of the Khazar State, and the Scandinavian campaigns in the Caucasus, closely intertwined with the history of transport and communications connecting the north and south through the Volga-Caspian route. In a later era, the interests of the Mongolian Uluses, and then the political and economic aspirations of the Ottoman Empire, the Safavid State, and Russia, collided or combined on these routes. The article discusses trade contacts existing between the north and the south in the 15th and first half of the 17th century along the routes on the western coast of the Caspian Sea.

  • The Silk Road tied the globe together for the first time by producing an early globalization phenomenon. Some consider that the ancient Silk Road disintegrated around the $18^{th}$ century CE due to the fall of the Muslim empires and the kingdoms between Asia and Europe. However, the maritime trade among East Asia and the Spanish dominion on the American continent reactivated the ancient Silk Road on some levels, and maintained trade dynamics until the $19^{th}$ century. This was possible because of Mexican silver and trade spots. Notwithstanding its historical background, Mexico seems so far away from the new Silk Road, or the Belt and Road Initiative in the $21^{st}$ century. Thus, this paper analyzes Mexico's historic and current role concerning the Silk Road. First, I conceptualize and compare the ancient Silk Road and Belt and Road Initiative through the lens of complex interdependence theory. I propose that, unlike the ancient Silk Road, the Belt and Road Initiative is a case of an induced complex interdependence. Second, I study the Manila Galleons' dynamics in order to trace the ancient ties with the Silk Road. I emphasize Mexican silver's contribution to East Asian economies and the importance of Mexico's role in the East Asia-Spanish trade. Consequently, I analyze Mexico's position in the Belt and Road Initiative. Finally, I present some concluding remarks about Mexico's role in the Silk Road.

  • This paper is an art historical attempt to discuss the transfer and transmission of a certain visual idiom along the Silk Roads and to show the multi-dimensionality of the trans-regional, trans-cultural movement. The motifs of grapes and grapevines are discussed here for this purpose, including the grape-and-vine motif mixed with other animated figures and plants. A special emphasis is on China and its reception, but regional varieties within East Asia are also discussed. The motif is one of the most longstanding and versatile visual idioms, widely distributed along the regions of the Silk Roads. This deceptively familiar motif came to China, where grapes and viticulture were introduced far later than the West. The West developed various symbolisms ranging from manic revelry and heavenly unity with mystic beings, to royalty and power in different cultures. In China, this visual idiom was eagerly received in association with something exotic and re-interpreted in the context of Chinese culture. Without active viticulture, the motif transformed itself into beautiful design patterns and space fillers in China and East Asia. The natural appeal of jewel-like grapes acquired new meanings of fertility and happiness in the traditional East Asian cultural context. To see the cultural effect of viticulture on the visualization of this motif, the Islamic reception of the motif is briefly touched upon when countries to the West of China (서역 西域) were fully Islamized and heavily affected by the prohibition of alcoholic drinking.

  • Ali Bey $H{\ddot{u}}seyinzade$ (1864-1940) was one of the most significant Azerbaijani Turkish intellectuals in the late nineteenth and early twentieth centuries, formulating Azerbaijani national identity around its Turkish, Islamic and territorial dimensions. His solution to the ambiguities of the identity crisis among the Turkic-Muslim people of Azerbaijan was Turkification, Islamization and Europeanization for the Turkic and Muslim peoples of the Caucasus and Ottoman Turkey. Ali Bey $H{\ddot{u}}seyinzade$ was an influential Azerbaijani Turkish intellectual who had a direct impact on Turkish nationalists in the late Ottoman Empire and early Republican Turkey. $H{\ddot{u}}seyinzade^{\prime}s$ formulation of the triple processes of Turkification, Islamization and Europeanization spread among the Azerbaijani and Ottoman Turkish intellectuals in their respective countries. This article aims to discuss the ideas of Ali Bey $H{\ddot{u}}seyinzade$, especially regarding nationality, religion and Westernism and their impact on intellectuals and policy makers in the Caucasus and Turkey. His physical odyssey from Tsarist Russia into the Ottoman Empire is indicative of his ideological proclivities and his subsequent influence on the Turkish-speaking peoples in the two major empires in the late nineteenth and early twentieth centuries.

  • Transnational exchange has been an inseparable part of both the ancient and modern Silk Road. This paper shows how Rumi (1207-1273), a famous Persian Sufi poet, travels along the Silk Road in the $21^{st}$ century. With the birth of a Rumi phenomenon in the West, Silk Road artists have rediscovered and adapted him for different purposes. Elif Shafak, the Turkish-British novelist and women's rights activist, espouses feminist beliefs in her bestseller, The Forty Rules of Love (2010). Benefiting from the views of feminist theorists like Woolf, de Beauvoir and Friedan, this paper reveals how Shafak appropriates Rumi for her feminist purposes. Forty Rules of Love's protagonist, Ella Rubinstein is analyzed, compared and contrasted with her former literary counterparts Pinhan and Zeliha, heroines of Shafak's previous novels. By adapting Rumi's definition of equality, Shafak shows how egalitarianism must pervade the relationship between women and men. The adaptation of Rumi's ideas regarding the equality of sexes finds a different dimension when Shafak reveals that all humanity possesses femininity and masculinity at the same time. By means of ideas prevalent in the ancient Silk Road, the five classical elements theory, and the yin and yang principle, Shafak portrays unity within contradictions. It is concluded that although individuals might belong to different typologies of the five symbolic elements of nature, they can at the same time complement one another's inharmonious personalities peacefully. The process of integration of female and male sexes can be expedited by opening up one's heart to a universal love.

  • The family as a social institution has survived most diverse political periods and appears resilient or at least able to reconstitute itself even in the aftermath of destructive events such as wars. Age at first marriage is one possibility to systematize the strategies that families follow in times of internal conflicts (e.g., civil wars), external interventions or peaceful times. The authors found that age at first marriage correlates with socio-political events whereas perceptions of insecurity lead to a decline in marital age. This paper is based on three case studies that the authors have conducted through ethnographic methods among Tajiks in the cities Kulob, Khujand, and Mazar-e Sharif in Tajikistan and Afghanistan. Combining Grounded Theory with the genealogical methods from social anthropology in order to generate demographic data, the authors introduce the method of grounded demography as a way to generate demographic data through ethnographic methods. Grounded demography offers a way to produce statistical data grounded in ethnographic research.
