With the rapid development of global industry and increasingly frequent product circulation, the separation and detection of chiral drugs/pesticides are becoming increasingly important. The chiral nature of substances can result in harm to the human body, and the selective endocrine-disrupting effect of drug enantiomers is caused by differential enantiospecific binding to receptors. This review is devoted to the specific recognition and resolution of chiral molecules by chromatography and membrane-based enantioseparation techniques. Chromatographic enantiomer separations with chiral stationary phase (CSP)-based columns and membrane-based enantiomer filtration are detailed. In addition, the unique properties of these chiral resolution methods have been summarized for practical applications in the chemistry, environment, biology, medicine, and food industries. We further discussed the recognition mechanism in analytical enantioseparations and analyzed recent developments and future prospects of chromatographic and membrane-based enantioseparations.

Recent developments related to the emergence of pottery in East Asia and neighbouring regions are presented. According to a critical evaluation of the existing evidence, the oldest centres with pottery in East Asia are situated in South China (dated to c. 18 000 calBP), the Japanese Islands (c. 16 700 calBP), and the Russian Far East (c. 15 900 calBP). It is most likely that pottery-making appeared in these regions independently of each other. In Siberia, the earliest pottery now known isfrom the Transbaikal region (dated to c. 14 000 calBP). However, it did not influence the more westerly parts of Siberia in terms of the origin and spread of pottery-making.

A restrained relationship between the Soviet Union and Japan great military and economic powers and geographically close neighbors in Northeast Asia -is an international anomaly of considerable magnitude. Resolution of this anomaly has been delayed for the last 40 years by several factors, some bilateral and others involving third parties. Yet, it would be surprising if the two nations were anything but restrained and suspicious of each other. Historically they fought each other in East Asia since the turn of the century. The two countries have very little in common in social, political, and cultural spheres. For this and other reasons, the Soviet image in Japan is extremely unfavorable. Yet the growth of both nations' power -militarily for Moscow and economically for Tokyo - has gradually and steadily increased the mutual necessity for improving relations. Given Soviet military strength in the Pacific, Tokyo has attempted, without much success, to have its relations with Moscow in a "self-confident and unhostile" manner.f Moscow's policy toward Tokyo was somewhat inactive, if not negative, resulting in more damage to itself than to the Japanese. Recently this policy appears to be changing. This essay examines the probable causes of this change, actual processes of improvement, remaining obstacles, and future prospects.
