Recent development of information technologies produces a lot of community services. Social Network Service is one of the community services on the world wide webs. In the Social Network Service, a user can register other users as friends and enjoy communication through a virtual message. Previous researches show a few social service methods using manually generated tagging. However, the manual social tagging is not widely used in many social network services. Moreover, they do not consider ubiquitous computing environment. We propose a recommendation method for social service using contexts in ubiquitous environment. Our method scores documents based on context tags and social network services. Our social scoring model is computed by both a tagging score of a document and a tagging score of a document that was tagged by a user's friends.

Digital twins are digital replicas of objects and systems in the real world. These digital replicas in a virtual environment can be connected with smart sensors and a variety of analyses, and simulations of real-time data from these sensors enable effective the operation, rapid feedback, and future predictions of real world phenomena. Until now, digital twins have been adopted and used mainly in the field of manufacturing, especially for smart factories. As digital twins are expected to be useful not only for productivity improvement but also for social problem solving, it is predicted that they will be extended to other fields such as those of transportation and cities. Digital twins will especially help realize smart cities through real-time monitoring, operation, and predictions using virtual digital twin cities. This paper summarizes the trends in digital twins for smart cities, the concept of digital twins, their application to smart cities, the strategies of various countries, and the development status of companies.

The article examines the axiological psycho-philosophical understanding of the phenomenon of money and its value role in modern society. The traditional and virtual context of the representation of the money phenomenon is considered.Following the ideas of G. Simmel, the authors consider money not only as a purely economic, but also a psycho-philosophical, cultural and social phenomenon. Money appears as a result of cultural development of the world and gradually forms a monetary culture as a space of economic and social interaction of people. Under the influence of the monetary culture of one or another historical period, the character of a person's economic activity, values and life orientations are formed. Modern money culture is often called financial civilization. Peculiarities of modern monetary culture are studied, its main features and problems are determined in the article. The problem of the peculiarities of the constructive and destructive attitude of the individual towards money is identified; a psycho-philosophical and cultural-identification typology of people is described, which is based on clinical observations and interpreted through the prism of psychoanalytic theory. The concept of money is highlighted from the standpoint of a social-psychological approach. The theoretical foundations of money's influence on the decision-making process and human behavior are also revealed.

Companies operating in social network platforms continue to improve and expand their marketing techniques. This study examines the practice of "gating", which involves virtual barriers between social network users and company content. Gates demand mandatory user endorsements, in the form of a Facebook "Likes", Twitter "retweets" etc., to gain access to company content, such as coupons and rewards,. Gating practices demand a mandatory endorsement before any content consumption takes place. Thus, while user endorsements are assumed to arise voluntarily from trusted known sources, gating practices would appear to violate this assumption. However, whether this violation lessens the effectiveness of gating practices still requires empirical validation. We investigate this question through the use of a unique panel data set that includes data on "like" endorsements obtained from a number of real-world Facebook business pages. Results of the study show that gating practices are effective for endorsement solicitation; however, gates may interfere with more traditional marketing activities.

This paper, as a conlcusion to this special issue, presents the future work that is being carried out at NTU Singapore in collaboration with Microsoft Research and Microsoft Azure for Research. For our research team the real frontier research in world histories starts when we want to use computers to structure historical information, model historical narratives, simulate theoretical large scale hypotheses, and incent world historians to use virtual assistants and/or engage them in teamwork using social media and/or seduce them with immersive spaces to provide new learning and sharing environments, in which new things can emerge and happen: "You do not know which will be the next idea. Just repeating the same things is not enough" (Carlo Rubbia, 1984 Nobel Price in Physics, at Nanyang Technological University on January 19, 2016).

The Internet can deliver various information and services at the lowest cost without time and space constraints while targeting the world among all existing means of communication. Unlike traditional media such as TV, newspapers, and radio in the past, promotions through mobile environments allow target customers to use two-way low-cost, high-efficiency promotional strategies regardless of time and place. With the development of the Internet, social media has developed into a place to acquire information about favorite companies and their products. Social media greatly contributes to the production of text, photos, videos, and various networks, and has expanded global communication and communication media through the interaction and sharing of various information. In addition, through social media, users can communicate in various ways, reveal themselves, and share and exchange information such as knowledge and personal thoughts. In line with these changes, corporate marketers and sellers are striving to provide consumers with appropriate information more quickly. We aims to find out about social media marketing strategies useful for companies.

가상세계란 전자적 커뮤니케이션에 의해 네트워크화된 3차원 컴퓨터 그래픽 기반의 인터랙티브 환경을 말한다. 오늘날 구현된 가상세계는 기존의 매체에서는 볼 수 없었던 장시간의 몰입을 가능하게 했고, 현실의 노동에 필적할 만큼 힘들고 지루한 장시간의 플레이는 일과 놀이의 경계를 무화시키며 재미노동의 개념을 탄생시켰다. 이러한 재미노동을 '노동을 자연에 가함으로써 자연이 부여한 물리적 한계를 극복하고 자연을 자신에게 더 고유한 존재로 만드는' 인간의 본질로서의 노동으로 긍정한다면, 정보사회에서의 구조적 실업 문제를 해결할 수 있는 획기적인 거대 서비스 분야 중 하나라고 조심스럽게 가정할 수 있다. 또한 재미노동은 돈과 시간과 관심을 지불한 만큼 의미 있는 경험을 하기 원하는 사용자들의 지각 능력과 행위주체성에 부합하는 새로운 형태의 노동일 수 있다. 이러한 현상은 다양한 가상세계를 편력하는 사이버 산책자로서 정의되었던 기존의 사용자 정체성 개념에 반론을 제기하면서, 가상세계의 사용자들은 오히려 하나의 가상세계에 오래 머물며 지속적이고 발전적으로 재미노동을 행하는 존재, 즉 주민의 정체성을 형성하고 있음을 나타낸다. 이렇게 가상세계의 사용자들이 주민성을 형성함에 따라 단체 행동권과 시민참여의 새로운 양식이 확산되어 가고 있으며, 이러한 현상이 사회적으로 미치는 영향을 관찰하는 일이 매우 중요해질 것이다.

주거는 현실세계에서 중요한 의미를 가진다. 그에 비해 메타버스의 주거는 다양한 메타버스 서비스 플랫폼들에서 만들어지고 있으나 아직까지 다른 건축 유형들에 비해 관심이 부족하다. 본 연구는 주거의 의미, 유형과 특성에 기초하여 현실세계의 주거 모델을 바탕으로 메타버스 주거의 개념을 확립하고 발전 방향을 모색하고자 한다. 이를 위해 선행연구 조사, 기존 주거 모델 분석, 메타버스 주거 사례 연구 및 설문조사를 실시하였다. 또한 분석된 내용을 토대로 물리적, 사회적, 개인적 모델을 포함하는 메타버스 주거 모델을 제시하였고, 물리적 모델의 공간 꾸미기 및 피난처 특징과 개인적 모델의 자기표현 특징을 메타버스 주거를 가장 잘 나타낼 수 있는 특징으로 파악하였다. 본 연구의 결과가 향후 메타버스 가상세계 연구 및 서비스 플랫폼 개발에 도움이 될 수 있을 것이라 기대한다.
