This book primarily addresses various game theory phenomena in the context of management practice. As such, it helps readers identify the profound game theory principles behind these phenomena. At the same time, the game theory principles in the book can also provide a degree of guidance for solving practical problems. As one of the main areas in management research, there is already an extensive body of literature on game theory. However, it remains mainly theoretical, focusing on abstract arguments and purely numerical examples purely. This book addresses that gap, helping readers apply game theory in their actual management or research work.

Representatives of the Hezhe people (Nanai people) live in Russia and China. This article is about fish in their traditional culture. Fish and everything related to it can be considered a cultural symbol of the Hezhe people. This is due to the peculiarities of the culture of the region located along the Amur, Sungari and Ussuri rivers. Analyses of historical documents and artistic works show the great importance of working with fish skin in the life of the Hezhe. Material production and spiritual life of the Hezhe have been closely connected with fish for many generations. It has been revealed that the high fertility of fish, one of the main sources of food and material for sewing clothes, caused the Hezhe people to revere fish in ancient times. It has been established that the Hezhe people had a rich culture. Fish became one of the most widespread zoomorphic motifs of Hezhe ornamental art. The image of fish on the products was given a high cultural meaning. This image left a vivid trace in both Chinese and Russian culture — from totemism to decorative items. The article presents an analysis of fish as a cultural symbol based on the materials of Chinese and Russian museum collections. The study of fish in the traditional culture of Hezhe will expand the existing knowledge about the nature and specificity of ethno-cultural interaction between China and the peoples of the Amur region for many centuries. An attempt is made to tell about the specifics of Chinese cultural meaning of decorative items based on fish skin. For the first time the authors treat the ornamentation of fish patterns in the traditional culture of Hezhe in a systematized form. This will allow researchers to familiarize themselves with information from Chinese sources to identify typical images of fish in Hezhe for further study of the topic of fish skin processing as art in Russia.

IntroductionThere is no doubt that highly active antiretroviral therapy (ART) has decreased the total mortality of HIV‐infected populations drastically, and HIV has become a chronic and manageable condition. However, complications after long‐term treatment of ART tarnished the great efforts. We aimed to study the effects of add‐on lipid‐lowering agents on ART for patients who developed hyperlipidemia after HIV treatment. The risk factors for failure to normalize lipid profile were analyzed.Materials and MethodsHIV‐infected patients who visited outpatient clinics of Taoyuan General Hospital between July 2013 and January 2014 were retrospectively reviewed. Subjects who needed the management of dyslipidemia were enrolled. Total cholesterol (TC), triglyceride (TG), high‐density lipoprotein (HDL) and low‐density lipoprotein (LDL) were regularly followed up for at least 6 months. ART modification and add‐on lipid‐lowering agents for dyslipidemia were analyzed.ResultsThere were 926 HIV‐infected patients undertaking ART in the hospital during the study period. Among them, 23.2% of patients undergoing lopinavir‐based regimen, 8.4% efavirenz‐based regimen, 4.2% darunavir‐based regimen, 3.3% nevirapine‐based regimen, 2.4% raltegravir‐based regimen and 2.3% atazanavir‐based regimen developed dyslipidemia. There were 76 patients (8.2%) who needed management of dyslipidemia (Table 1). Among them, 97% received lipid‐lowering agents, and 17% switched to lipid‐friendly ART (atazanavir, boosted atazanavir, boosted darunavir, nevirapine or raltegravir) despite statins or fibrates used. Mean values (mg/dL) of TC/ TG/LDL were, respectively, 279/422/139 before enrolment, 209/270/114 at 4–12 weeks and 206/250/121 at 48 weeks (p<0.05 for baseline compared to 4–12 weeks and 1 year, respectively). No obvious changes in HDL were noted. In Cox proportional hazard model, patients who received lopinavir (adjusted hazard ratio [aHR], 0.293; 95% confidence interval [CI], 0.110–0.784; p=0.015) or efavirenz (aHR, 0.185; 95% CI, 0.072–0.447; p=0.005) were less likely to achieve normalization of TC (<200 mg/dL) and TG (<200 mg/dL). Modification of ART (aHR, 1.807; 95% CI, 0.828–3.944; p=0.137) did not change the outcome (Figure 1).ConclusionsEfavirenz and lopinavir were independent factors for the persistence of dyslipidemia despite adding lipid‐lowering agents. ART associated with a favourable lipid profile would be considered in the modern era, and this certainly leaves the question of cost versus benefit.

abstract: The activities of Mongolic-speaking populations, a large group of people in eastern Eurasia, have important impacts on the history of East Asia and other parts of Eurasia. Most previous genetic research of East Asian populations, including ancient DNA studies, has involved samples from Mongolic-speaking populations or their ancient relatives. This review summarizes frequency data of paternal Y-chromosome haplogroups from all available literature about Mongolic-speaking populations from 1999 to 2019. Fourteen paternal components were identified, and six of them are proposed as major and common components in ancestor groups of Mongolic-speaking populations. The article thoroughly discusses the possible origin, migration patterns, and the roles of these six components in the evolutionary history of Mongolic-speaking populations, as well as implications of present achievements in human genetics for future multidisciplinary research in ethnology, history, archaeology, and linguistics.
