가상인간은 가상공간(가상 현실, 혼합 현실, 메타버스 등)에서 Unity와 같은 3D Engine 전용 모델링 도구로 구현된다. 실제 사람과 유사한 외모, 목소리, 표정이나 행동 등을 구현하기 위해 다양한 가상인간 모델링 도구가 도입되었고, 어느 정도 수준까지 인간과 의사소통이 가능한 가상인간을 구현할 수 있게 되었다. 하지만, 지금까지의 가상인간 의사소통 방식은 대부분 텍스트 혹은 스피치만을 사용하는 단일모달에 머물러 있다. 최근 AI 기술이 발전함에 따라 가상인간의 의사소통 방식은 과거 기계 중심의 텍스트 기반 시스템에서 인간 중심의 자연스러운 멀티모달 의사소통 방식으로 변화할 수 있게 되었다. 본 논문에서는 다양한 대화 데이터셋으로 미세조정한 인공신경망을 사용해 사용자와 자연스럽게 대화 할 수 있는 가상인간을 구현하고, 해당 가상인간이 생성하는 문장의 감정값을 분석하여 이에 맞는 표정을 발화 중에 나타내는 시스템을 구현하여 사용자와 가상인간 간의 실시간 멀티모달 대화가 가능하게 하였다.

The concept of social capital has recently been highlighted in most fields of social science because social capital is believed to be an alternative of market and government failures. However, social capital is of high ambiguity that hinders in conceptualizing and modeling that can differs from the premises, such as whether social capital lies in individual actors or collective substances, or whether social networks are functioning by rationality or emotion. This study therefore tries to examine the concept of social capital and suggest 6 types of it following by the anthropologic concept of 'reciprocity' as well as to provide fruitful discussions on the introduction of social capital variables to System Dynamics modeling of sustainable development. Conclusively, the introduction of social capital to the integration models of environment-economy-society should be based on strongly understanding the social networks, individual identities, and local particularities of the relevant localities in order to enhance the structural validity and applicability of sustainable development models in System Dynamics.

In the era of COVID-19 pandemic, COVID related keywords, news and SNS data are pouring out. With the help of the data and LDA topic modeling, we can check out what media reports about COVID-19 and vaccines. Also, we can be clear how the public reacts to the vaccine on social media and how this is related with the increasing number of COVID-19 patients. By using sentimental analysis methodology, we can get to know about the different kinds of reports that Korea media send out and get to know what kind of emotions that each media company uses in majority. Through this procedure, we can know the difference between the Korean media and the foreign ones. Ultimately, we can find and analyze the keyword that suddenly rose during the COVID-19 period throughout this research.

비디오 데이터에 존재하는 감정을 처리하는 것은 지능적인 인간과 컴퓨터와의 상호작용을 위해서 매우 중요한 일이다. 이러한 감정을 추출하기 위해서는 비디오로부터 감정에 관련된 특징들을 검출하기 위한 컴퓨팅 모델을 구축하는 것이 바람직하다. 본 논문에서는 비디오 셧에 존재하는 저급 특징들의 확률적인 분포를 이용하여 감정 이벤트 발생에 관련된 통계학적인 모델을 제안한다. 즉, 비디오 셧의 기본적인 특징을 추출하고 그 특징을 통계적으로 모델화 하여 감정을 유발하는 셧을 찾아낸다. 비디오 셧의 특징으로는 칼라, 카메라 모션 및 셧 길이의 변화를 이용한다. 이러한 특징들을 EM(Expectation Maximization) 알고리즘을 이용하여 GMM(Gaussian Mixture Model) 으로 모델링하고, 감정과 시간과의 관계를 MLE(Maximum Likelihood Estimation)를 이용하여 시간에 따른 확률분포 모델로 구성한다. 이런 두 개의 통계적인 모델들을 융합하여 베이시안 분류법을 적용하여 비디오 데이터로부터 감정에 관련된 셧을 찾아낸다.

Airport is not only a public facility but a place where multiple cultural and ethnic groups are visiting. It has been reported though several researches that the level of emotional labor is more heavier than any other job. The more complex our society become, the more frequently emotional labor has been focused. Emotional labor became recently the issue of integrated studies above. Considering the level of emotional labor of airport employees, this paper believes their emotional labor has not been focused compared to such as tourism and service industry. This paper tried to research empirically the impact of internal marketing on airport employees' customer-oriented attitude based on their emotional labor using SEM (Structural Equation Modeling). According to the SEM results, it was proven that 'Autonomy of Airport Employee', a latent variable of internal marketing has a significant negative effect on employees' outside emotion. The outside emotion has also a significant effect on their customer-oriented attitude. It could be concluded the effort to increase decision making authority of employees should be implemented to provide them with deeper customer oriented insight.

The RT(Robot Technology) has been developed as the next generation of a future technology. According to the 2002 technical report from Mitsubishi R&D center, IT(Information Technology) and RT(Robotic Technology) fusion system will grow five times larger than the current IT market at the year 2015. Moreover, a recent IEEE report predicts that most people will have a robot in the next ten years. RCP(Robotic Cellular Phone), CP(Cellular Phone) having personal robot services, will be an intermediate hi-tech personal machine between one CP a person and one robot a person generations. RCP infra consists of $RCP^{Mobility}$, $RCP^{Interaction}$, $RCP^{Integration}$ technologies. For $RCP^{Mobility}$, human-friendly motion automation and personal service with walking and arming ability are developed. $RCP^{Interaction}$ ability is achieved by modeling an emotion-generating engine and $RCP^{Integration}$ that recognizes environmental and self conditions is developed. By joining intelligent algorithms and CP communication network with the three base modules, a RCP system is constructed. Especially, the RCP interaction system is really focused in this paper. The $RCP^{interaction}$(Robotic Cellular Phone for Interaction) is to be developed as an emotional model CP as shown in figure 1. $RCP^{interaction}$ refers to the sensitivity expression and the link technology of communication of the CP. It is interface technology between human and CP through various emotional models. The interactive emotion functions are designed through differing patterns of vibrator beat frequencies and a feeling system created by a smell injection switching control. As the music influences a person, one can feel a variety of emotion from the vibrator's beats, by converting musical chord frequencies into vibrator beat frequencies. So, this paper presents the definition, the basic theory and experiment results of the RCP interaction system. We confirm a good performance of the RCP interaction system through the experiment results.
