All social insects defend their colony from predators, parasites, and pathogens. In Oster and Wilson's classic work, they posed one of the key paradoxes about defense in social insects: Given the universal necessity of defense, why then is there so much diversity in mechanisms? Ecological factors undoubtedly are important: Predation and usurpation have imposed strong selection on eusocial insects, and active defense by colonies is a ubiquitous feature of all social insects. The description of diverse insect groups with castes of sterile workers whose main duty is defense has broadened the purview of social evolution in insects, in particular with respect to caste and behavior. Defense is one of the central axes along which we can begin to organize and understand sociality in insects. With the establishment of social insect models such as the honey bee, new discoveries are emerging regarding the endocrine, neural, and gene regulatory mechanisms underlying defense in social insects. The mechanisms underlying morphological and behavioral defense traits may be shared across diverse groups, providing opportunities for identifying both conserved and novel mechanisms at work. Emerging themes highlight the context dependency of and interaction between factors that regulate defense in social insects.

Immediately after the liberation, the health care system debate was studied focusing on the orientation of the American and Soviet medical systems, roughly divided into Lee Yong-seol and Choi Eung-seok. However, the existence of people who are not explained in the American and Soviet health care systems’ orientation led to the need to reconsider the existing premise. Therefore, this study identifies the characters that were not explained in the perspective of existing studies, and reevaluates the arguments of Lee Yong-seol and Choi Eung-seok. This paper raises the following questions: First, what is the background of the policy orientation that Lee Yong-seol and Choi Eung-seok had? Second, if there are people who made different arguments from Lee Yong-seol and Choi Eung-seok, what direction did they set and argue? third, how the orientations of Lee Yong-seol and Choi Eung-seok and etc. converge into the answer to the Joint Soviet-American Commission? In response to theses questions, this study confirms the following: first, Lee Yong-seol’s and Choi Eung-seok’s health care policies were established based on realism and empiricism. As a policyholder, Lee Yong-seol emphasized withholding medical state administration and raising the level of medical education and medical systems according to the condition at that time, although the American system was mobilized by Lee as the basis for his judgment and administrative assets. On the other hand, Choi Eung-seok aimed for a Soviet-style systems in health care but this was realistically put on hold. Choi insisted on the establishment of the Medical Service Associations and rural cooperative hospitals that appeared in Japan’s medical socialization movement. In summary, immediately after the liberation, Lee Yong-seol’s and Choi Eung-seok’s policy arguments were based on policies that could be implemented in Korea, and the American system and Soviet system served as criteria for the policy resources. Second, Jeong Gu-chung and Kim Yeon-ju show that the topography of the health care debate immediately after the liberation was not represented only by Lee Yong-seol and Choi Eung-seok. Both Jeong and Kim were consequently led to medical socialization, which was the implementation of a health care system that encompasses social reform, but the context was different. Jeong drew the hierarchy of the health care system, which peaked in the United States, from the perspective of social evolution based on his eugenics, but the representation suitable for Korea was the Soviet model absorbed into his understanding. On the contrary, Kim argued that representations suitable for Korea should be found in Korea. As national medical care, Kim’s idea aimed at a medical state administration that provides equal opportunities for all Koreans. Third, the aspect of convergence to the Joint Soviet-American Commission reply proposal was complicated. Among the policies of Lee Yong-seol, the promotion of missionary medical institutions and the gradual planning of medical institutions converged into the three organizations’ proposal, and Choi Eung-seok’s policy was almost the same as that of the Democracy National Front and the South Korean Labor Party. However, the medical system of Japan, the colonial home country, appears to have been based on Lee Gap-soo, chairman of the Korean Medical Association in the colonial period, and the plan was in line with the use of the union system of the left-wing organizations’ proposal in the south. It was in accordance with a common task to expand health care from colonial conditions to different status.

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon (attribute) and as a cultural phenomenon (sign). Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested.

In order to survive and develop, organizations need to create structures able to anticipate tendencies of economic and social evolution. Therefore, the strategic planning of the organization, the human resources included, represents the most important managerial activity of long run effects. Sadly, the Covid-19 pandemic changed and continues to change the human resources organization. Thus, the organization itself has to assess permanently. The organization needs to assess its own structure, the efficiency of the information and resources, the ability of the organization’s adjustment to the external conditions. The organization has to assess the personnel’s abilities to make use of the new technologies, the capacity of investing in improving and re-training the personnel etc.

The anthropoid primates are known for their intense sociality and large brain size. The idea that these might be causally related has given rise to a large body of work testing the ‘social brain hypothesis'. Here, the emphasis has been placed on the political demands of social life, and the cognitive skills that would enable animals to track the machinations of other minds in metarepresentational ways. It seems to us that this position risks losing touch with the fact that brains primarily evolved to enable the control of action, which in turn leads us to downplay or neglect the importance of the physical body in a material world full of bodies and other objects. As an alternative, we offer a view of primate brain and social evolution that is grounded in the body and action, rather than minds and metarepresentation. This article is part of the theme issue ‘Systems neuroscience through the lens of evolutionary theory’.

Cognitive variation is proposed to be the fundamental underlying factor that drives behavioral variation, yet it is still to be fully integrated with the observed variation at other phenotypic levels that has recently been unified under the common pace-of-life framework. This cognitive and the resulting behavioral diversity is especially significant in the context of a social group, the performance of which is a collective outcome of this diversity. In this review, we argue about the utility of classifying cognitive traits along a slow-fast continuum in the larger context of the pace-of-life framework. Using Tinbergen’s explanatory framework for different levels of analyses and drawing from the large body of knowledge about honeybee behavior, we discuss the observed interindividual variation in cognitive traits and slow-fast cognitive phenotypes from an adaptive, evolutionary, mechanistic and developmental perspective. We discuss the challenges in this endeavor and suggest possible next steps in terms of methodological, statistical and theoretical approaches to move the field forward for an integrative understanding of how slow-fast cognitive differences, by influencing collective behavior, impact social evolution.
