Question: What country's social system is commented on is the K-horror film series that began with "Whispering Corridor's"?
Context: In sociology, a social system is the patterned network of relationships constituting a coherent whole that exist between individuals, groups, and institutions.  The term refers to the formal structure of role and status that can form in a small, stable group.  An individual may belong to multiple social systems at once; examples of social systems include nuclear family units, communities, cities, nations, college campuses, corporations, and industries.  The organization and definition of groups within a social system depend on various shared characteristics such as location, socioeconomic status, race, religion, societal function, or other distinguishable features. A Blood Pledge (Hangul: 여고괴담 5: 동반자살 ; RR: "Yeogogoedam 5: dongbandjasal " ; also known as Whispering Corridors 5: A Blood Pledge and Suicide Pact) is a K-Horror film, and the fifth installment of the "Whispering Corridors" series of South Korean horror films set in girls' high schools that began with 1998's film of the same name.  Aside from the setting and overall themes, it is unrelated to the other films in the series. Whispering Corridors () is a 1998 South Korean horror film.  It was part of the explosion in Korean cinema following the liberalization of censorship in the aftermath of the end of the country's military dictatorship, and makes a strong social commentary on authoritarianism and conformity in the harsh South Korean education system. The Uninvited is a 2009 American psychological horror film directed by the Guard Brothers, and starring Emily Browning, Elizabeth Banks, Arielle Kebbel and David Strathairn.  It is a remake of the 2003 South Korean K-Horror film "A Tale of Two Sisters", which is in turn one of several film adaptations of the Korean folk tale Janghwa Hongryeon jeon.  The film received mixed reviews. The knowledge gap hypothesis explains that knowledge, like other forms of wealth, is often differentially distributed throughout a social system.  Specifically, the hypothesis predicts that "as the infusion of mass media information into a social system increases, segments of the population with higher socioeconomic status tend to acquire this information at a faster rate than the lower status segments, so that the gap in knowledge between these segments tends to increase rather than decrease".  Phillip J. Tichenor, then Associate Professor of Journalism and Mass Communication, George A. Donohue, Professor of Sociology, and Clarice N. Olien, Instructor in Sociology – three University of Minnesota researchers – first proposed the knowledge gap hypothesis in 1970. The AGIL paradigm is a sociological scheme created by American sociologist Talcott Parsons in the 1950s.  It is a systematic depiction of certain societal functions, which every society must meet to be able to maintain stable social life.  The AGIL paradigm is part of Parsons's larger action theory, outlined in his notable book "The Structure of Social Action", in "The Social System" and in later works, which aims to construct a unified map of all action systems, and ultimately "living systems."  Indeed, the actual AGIL system only appeared in its first elaborate form in 1956, and Parsons extended the system in various layers of complexity during the rest of his intellectual life.  Towards the end of his life, he added a new dimension to the action system, which he called the paradigm of the human condition; within that paradigm, the action system occupied the integral dimension. The "rhetoric of social intervention" (RSI) model is a systemic communication theory of how human beings symbolically constitute, maintain, and change social systems (e.g., organizations, societies, and cultures).  The RSI model was developed in the writings of communication theorist William R. Brown.  The model provides a framework for analyzing and interpreting social system change and its side effects from a communication perspective.  It also suggests a methodology for acting as an intervener to encourage and/or discourage social system change.  The model offers an alternative approach to understanding social system change by its emphasis on communication as the driver of change in contrast to models that focus on social, political, economic, and technological forces as catalysts for change.  The RSI model is envisioned as three communication subsystems that function as starting points for interpreting or enacting social system change.  The subsystems, known as attention, power, and need, form the RSI model framework.  This entry describes the assumptive foundations of the RSI model.  Then it discusses the attention, power, and need patterns of communication that that model identifies as points for generating social system change and continuity. Joe Robot and Anthropos were social robots at Media Lab Europe.  They were developed to aid in research on anthropomorphism and to explore the illusion of life and intelligence during the development of a meaningful social interaction between artificial systems and people.  As artificial systems enter our social space, we will inherently project/impose our interpretation on their actions similar to the techniques we employ in rationalising, for example, a pet's behaviour.  This propensity to anthropomorphise should not be seen as a hindrance to social system development, but rather a useful mechanism that requires judicious examination and employment in social system research.  A fundamental balance between function and form for human-robot interaction is necessary. The UNISIST model of information dissemination was proposed in 1971 by the United Nations.  UNISIST (United Nations International Scientific Information System) is a model of the social system of communication, which consists of knowledge producers, intermediaries, and users.  These groups of people (or actors) are different kinds of professionals.  The social system also contains institutes such as research institutes, publishers, and libraries.  The actors and institutions perform information services such as writing, publishing, storing and retrieving documents and information.  The actors are communicating in both formal and informal ways and they are producing different kinds of documents such as journal articles, books, book reviews, proceedings, bibliographies and catalogues, dictionaries, handbooks, encyclopedias and review articles. In the social sciences, social structure is the patterned social arrangements in society that are both emergent from and determinant of the actions of the individuals.  On the macro scale, social structure is the system of socioeconomic stratification (e.g., the class structure), social institutions, or, other patterned relations between large social groups.  On the meso scale, it is the structure of social network ties between individuals or organizations.  On the micro scale, it can be the way norms shape the behavior of individuals within the social system.
