The youth's rural rehabilitation movement started the crusade against illiteracy and poverty with all young educated elites including Whang Jongjin(a student of Yesan Public Agricultural High School) of the village, Shiryang-ri. Deoksan-myon. Yesan-gun. Among others, Patriot Youn(1908-1932) initiated the movement. The main projects of the agricultural extension were the Evening School(1926), Reading Club, the Woljin.Hoe(1929), Puheung.Won(1928), a Mutual Financing Association for Swine Farming, Sweet Potato Cultivation, Cooperative Planting, the Shuam.Sports Club and Consumer's Cooperative Society. The idea in Nongmindokbon (Famer's Text, 1927) is based on liberalism, equality, independence, a pioneer and cooperative spirit or realization of a physiocratical Utopia. Most references about Patriot Youn are concerned with his heroic deed in Shanghai, however the youth in Shinyang-Ri are typical agricultural extension workers or in other words, a forerunner of Saemaul Undong.

The recent listing of Preah Vihear Temple as a World Heritage Site has awakened a longtime simmering border dispute between Thailand and Cambodia over a few square kilometers surrounding the ancient Khmer Temple. While the listing of the site by UNESCO was expected to revive the economy of the impoverished border towns near the temple due to the increased tourism and funding for the preservation of the archeological site, it has had the opposite effect due to the sharp increase in violent conflict carried out by the armed forces and nationalist activists from both sides. Military skirmishes and violent protests have brought the local economy to a halt in addition to causing considerable physical damage to the local infrastructure and to the local transnational network of ethnic Kui, local business owners, Khmer and Thai villagers. This paper shows how the dispute is viewed and undertaken by three distinct communities involved in the conflict, the militaries, the metropolitan political elites and activists, and the local villagers. The three communities represent three different cultures of conflict with different interests and most importantly with differential access to the media and official representations of the dispute.

Alternate members of the Chinese Communist Central Committee are often overlooked regarding elite formation or even when assessing Chinese elites in general. This article focuses on the case of alternate members of the Central Committee from 1992 to 2007 in order to understand why some individuals will eventually be promoted and why some will never be. Through extensive quantitative testing, I argue that these non-promoted individuals differ from their counterparts in many ways, most of which can possibly be traced back to the type of formation they received early on. As such, the article concludes that Party School attendance and the age factor, through threshold analysis, are a significant factor helping us understand the difference between promoted and non-promoted houbu.

In this paper we consider three different cases and we apply Variational Approach (VA) to solve the non-natural vibrations and oscillations. The method variational approach does not demand small perturbation and with only one iteration can lead to high accurate solution of the problem. Some patterns are presented for these three different cease to show the accuracy and effectiveness of the method. The results are compared with numerical solution using Runge-kutta's algorithm and another approximate method using energy balance method. It has been established that the variational approach can be an effective mathematical tool for solving conservative nonlinear dynamical equations.

This study presents the hygro-thermo-electromagnetic mechanical vibration attributes of elastically restrained piezoelectric nanobeam considering effects of beam surface for various elastic non-ideal boundary conditions. The nonlocal Eringen theory besides the surface effects containing surface stress, surface elasticity and surface density are employed to incorporate size-dependent effects in the whole of the model and the corresponding governing equations are derived using Hamilton principle. The natural frequencies are derived with the help of differential transformation method (DTM) as a semi-analytical-numerical method. Some validations are presented between differential transform method results and peer-reviewed literature to show the accuracy and the convergence of this method. Finally, the effects of spring constants, changing nonlocal parameter, imposed electric potential, temperature rise, magnetic potential and moisture concentration are explored. These results can be beneficial to design nanostructures in diverse environments.

In this study we have considered the governing nonlinear equation of an eccentrically reinforced cylindrical shell. A new analytical method called He's Variational Approach (VA) is used to obtain the natural frequency of the nonlinear equation. This analytical representation gives excellent approximations to the numerical solution for the whole range of the oscillation amplitude, reducing the respective error of angular frequency in comparison with the variation approach method. It has been proved that the variational approach is very effective, convenient and does not require any linearization or small perturbation. Additionally it has been demonstrated that the variational approach is adequately accurate to nonlinear problems in physics and engineering.

In the current study, we consider a new class of analytical periodic solution for free nonlinear vibration of mechanical systems. Hamiltonian approach is applied to analyze nonlinear problems which occur in dynamics. The proposed method doesn't have the limitations of the classical methods and leads us to a high accurate solution by only one iteration. Two well known examples are studied to show the convenience and effectiveness of this approach. Runge-Kutta's algorithm is also applied and the results of it are compared with the Hamiltonian approach. High accuracy of the proposed approach reveals that the Hamiltonian approach can be very useful for other nonlinear practical problems in engineering.

This paper is devoted to the examination of the identity of the Sogdian descendants and their historical role in the second millennium CE. More specifically, it discusses the Sogdian connection to the later Iranic-speaking peoples of Central Asia, namely, the Sarts and the Tajiks. It then discusses the symbiotic relationship between the Sogdian descendants and the Mongols and the Mongol descendants (Chaghatays and Uzbeks) in Central Asia. In sum, this paper argues that the Sogdians did not perish after the Arab conquest of Central Asia in the eighth century CE. They survived under new exonyms Sart and Tajik. Like the Sogdians in pre-Islamic Central Asia, the Tajiks or Sarts played important historical roles in the Mongol and post-Mongol states of Central Asia, maintaining a symbiotic relationship with the nomad elites.

The paper discusses how the new EU Strategy towards Central Asia issued in May 2019 might be analyzed through the lens of the intensely debated transformations from the liberal to a post-liberal international order. The author claims that the EU's normative power is transforming from the post-Cold War predominantly liberal/ value-based approach, with democracy and human rights at its core, to a set of more technical tools and principles of good governance and effective management of public administration. The paper problematizes a nexus between the dynamics of the EU's nascent post-liberalism and the geopolitical challenges of the EU's growing engagement with illiberal regimes, focuses on direct encounters between the post-liberal EU and the illiberal elites in Central Asia, and seeks to find out the impact of these connections upon the EU's international subjectivity. In this context geopolitical dimensions of EU foreign and security policies, along with the specificity of the EU's geopolitical actorship in Central Asia, are discussed.

Afghanistan has experienced more than four decades of severe disruption, ever since the communist coup of April 1978 plunged the country into a state of disorder that was then severely aggravated by the Soviet invasion of Afghanistan in December 1979. Despite the high hopes that accompanied the overthrow of the Taliban regime in 2001, Afghanistan's path in the first two decades of the 21st century has proved to be anything but smooth, and this article highlights a confluence of challenges - political, diplomatic, and societal - that Afghanistan presently faces, challenges that in large measure account for the profound uncertainty that clouds its future. The article is divided into four sections. The first provides some context for the discussion of these three challenges. The remaining sections investigate the particular challenges - intra-elite rivalries, a fragile and defective peace process, and the underreported but grave threat to life and limb in Afghanistan resulting from the COVID-19 pandemic - in more detail. Together, these challenges highlight the dangers of wishful thinking about harsh realities.
