  • Emotion recognition is an essential component of complete interaction between human and machine. The issues related to emotion recognition are a result of the different types of emotions expressed in several forms such as visual, sound, and physiological signal. Recent advancements in the field show that combined modalities, such as visual, voice and electroencephalography signals, lead to better result compared to the use of single modalities separately. Previous studies have explored the use of multiple modalities for accurate predictions of emotion; however the number of studies regarding real-time implementation is limited because of the difficulty in simultaneously implementing multiple modalities of emotion recognition. In this study, we proposed an emotion recognition system for real-time emotion recognition implementation. Our model was built with a multithreading block that enables the implementation of each modality using separate threads for continuous synchronization. First, we separately achieved emotion recognition for each modality before enabling the use of the multithreaded system. To verify the correctness of the results, we compared the performance accuracy of unimodal and multimodal emotion recognitions in real-time. The experimental results showed real-time user emotion recognition of the proposed model. In addition, the effectiveness of the multimodalities for emotion recognition was observed. Our multimodal model was able to obtain an accuracy of 80.1% as compared to the unimodality, which obtained accuracies of 70.9, 54.3, and 63.1%.

  • The relevance of the published study lies in the fact that since the introduction of the first Global Distribution System, new information and communication technologies have constantly been changing the tourism industry. In the context of a current digital environment, travel agencies can't avoid participating in digital transformation processes aimed at rethinking operational models, skills, and organisational structures in the regions. This publication aims to present and provide a critical overview of digitalisation processes in tourism development in the regions of the Russian Federation, as well as to reflect on the challenges to the widespread digitalisation processes in the regional tourism sector. The subject of research is digitalisation processes, as they radically transform the modern tourism industry, in the regions as well. The pragmatic research paradigm was considered the most appropriate for the study of tourism digitalisation processes in the regions, as it does not require the selection of a specific theoretical basis for data collection. The pragmatic approach forms an alternative to classical theoretical approaches and serves as a particular type of grounded theory, combining both inductive and deductive methods. No software was used for the inductive part of the analysis. The deductive part was conducted using the qualitative data analysis software Nvivo 11. Given the wide diversity of interested parties in the regional tourism digital area, a stratified purposive sampling method was preferred due to its ability to adequately represent the full picture of the phenomenon under study. The selection and stratum criteria were chosen to maximise the representation of different perspectives in the regional tourism digital area. The novelty of the study is due to the digitalisation processes, with an implication of new needs, while opening up promising opportunities for more productive tourism business in the regions of the Russian Federation. Currently, e-tourism in the Russian Federation has become a subject of lively debate among scholars and practitioners. However, the involvement of advanced digitalisation technologies in the field of information processes in the regions of the Russian Federation is of a very sporadic character.

  • Nuclear Power Plants (NPP) are widely utilized around the globe from different base forms as it is one of the most dependable renewable resources that technological advancements have offered. However, different perceptions of the usage of NPPs emerged from different generations. The purpose of this study was to investigate the acceptance of nuclear energy as an alternative source of energy among Generation Z in the Philippines by utilizing an extended Theory of Planned Behavior (TPB) approach. An online questionnaire which consisted of 31 items was distributed using a purposive sampling approach and 450 respondents of Generation Z voluntarily answered. Structural Equation Modeling (SEM) showed that the knowledge regarding NPP had significant effects on risk perception and benefit perception which subsequently led to subjective norms. In addition, perceived behavioral control and subjective norms had significant effects on behavioral intention which led to nuclear acceptance. Interestingly, the respondents perceived the benefit of NPP as slightly higher than the perceived risk. With these, it was clear that the commissioning Nuclear Power Plant must consider as an alternative source of electric energy in the Philippines. Moreover, this study is one of the first studies that investigated the acceptance of NPP among Generation Z. Lastly, the model could be a basis to strengthen the acceptance strategy of opening NPP among Generation Z, particularly in developing countries.

  • As one of the most popular forms of electronic commerce, cross-border e-commerce provides numerous consumer benefits, such as broad and deep product assortments at low prices. However, consumers tend to exhibit high involvement in cross-border e-commerce purchases due to high risks associated with such purchases. The paper focuses on identifying causal relationships between e-commerce website traits (i.e., website trustworthiness, interactivity and convenience) and consumer satisfaction and along with loyalty. We proposed a reflective-reflective hierarchical model (first-order reflective and second-order reflective model) and used the Partial Least Square Analysis Statistical method to test the hypotheses. The results demonstrated that website trustworthiness, convenience and interactivity were all positively related to consumer satisfaction. Also, higher satisfaction led to stronger customer loyalty, which may well increase revisit intentions. We also compared the strength of each path from a website trait to satisfaction. Results illustrated that the path from website convenience to satisfaction is the strongest among the three website traits. In addition, we separately examined differences within Korean group and Chinese group. No statistically significant difference among website traits was found within Korean group. However, within Chinese group, we found that website convenience is the most important predictor of satisfaction. This indicates that Chinese consumers are more concerned about the website convenience than interactivity and trustworthiness when they make cross-border e-commerce purchases. Moreover, this study investigated possible differences between Korean and Chinese group. We used multi-group analysis of Smart PLS 3.0 to test the results. It was shown that the two groups do not display statistically significant difference in trustworthiness, interactivity, or convenience in influencing customer satisfaction. Finally, we presented further implications which are useful for understanding of the proposed model. Limitations and improvements of this research were presented, too.

  • Hepatitis C virus (HCV) is a major cause of chronic liver disease and is highly dependent on cellular proteins for viral propagation. Using protein microarray analysis, we identified 90 cellular proteins as HCV nonstructural 5A (NS5A) interacting partners, and selected telomere length regulation protein (TEN1) for further study. TEN1 forms a heterotrimeric complex with CTC and STN1, which is essential for telomere protection and maintenance. Telomere length decreases in patients with active HCV, chronic liver disease, and hepatocellular carcinoma. However, the molecular mechanism of telomere length shortening in HCV-associated disease is largely unknown. In the present study, protein interactions between NS5A and TEN1 were confirmed by immunoprecipitation assays. Silencing of TEN1 reduced both viral RNA and protein expression levels of HCV, while ectopic expression of the siRNA-resistant TEN1 recovered the viral protein level, suggesting that TEN1 was specifically required for HCV propagation. Importantly, we found that TEN1 is re-localized from the nucleus to the cytoplasm in HCV-infected cells. These data suggest that HCV exploits TEN1 to promote viral propagation and that telomere protection is compromised in HCV-infected cells. Overall, our findings provide mechanistic insight into the telomere shortening in HCV-infected cells.

  • This thesis is a study of content development utilizing media outlets to date through digital humans. The trend of global content is that the video content industry, including the character business, is growing. Lil Michela, who was selected as one of the 25 most influential people on the Internet by Time magazine in 2018, Nasua, who appeared in a SK Telecom commercial, and Rosie, who appeared in a Shinhan Bank commercial, are representative. Digital humans, which are driving new content, are computer-generated human characters with various characteristics and are referred to as virtual humans, metahumans, and cyber humans. With the rise of the metaverse after COVID-19, digital humans are being utilized in various forms such as media and marketing as an element of visual content. In the form of media, we can see that the boundaries between the offline and digital worlds are converging, and in the form of marketing, we can see that digital humans connect consumers and products more naturally. In the form of interaction, it is possible to achieve two-way communication through various methods of operation, and through these factors, it is possible to go beyond behavioral communication in the form of memorialization to emotional communication through AI technology. What can be seen through these processes is that through the currently developing digital human production methods and AI functions, not only experts but also non-experts can create quality contents, and new directions of contents will appear, and contents that can provide immediate feedback by bringing consumers and creators closer together have been studied.

  • 20세기 초 모더니즘 예술의 다양한 실험은 필름과 카메라의 발명과 함께 애니메이션을 탄생시켰다. 초창기에는 영화, 사진, 미술 등 예술가들에 의해 이미지와 시간을 접목한 다양한 분야의 이미지 실험이 이루어졌다. 그러나 이후 애니메이션이 상업적으로 성공을 거두면서 점차 흥미위주의 작품이 주류로 자리 잡아 갔으며, 초기 애니메이션의 실험적 특성은 소위 비주류 애니메이션으로 명맥이 유지되었다. 디즈니 애니메이션 역시 상업적인 작품을 제작하면서 초기작품의 실험적 형태, 움직임의 표현, 그리고 초현실주의적 관점이 반영돼 모더니즘 예술로 긍정적인 평가를 받아왔었지만, 점차 영화적 리얼리즘을 표방하여 3차원적 영상 이미지 표현에 몰두하였다. 그 예로 애니메이터들에겐 드로잉과 라이브액션 푸티지(liveaction footage)를 연구하는 클래스를 열어 사람과 동물의 움직임을 재현하는 테크닉을 발전시켜갔다. 또한 2차원 원급법의 표현적 한계를 극복하고자 기술적으로 멀티플레인 카메라(multiplane camera), 3D컴퓨터그래픽스와의 합성 등 이미지의 입체감을 강화시켜갔다. 더욱이 내용면으로 대중적인 동화 소재의 선택과 월트 디즈니 개인의 실사영화에 대한 관심은 애니메이션 연출에서 헐리우드 영화적 내러티브의 관습과 이미지 재현의 사실성을 강화시켜 초기 작품들이 갖고 있던 고유의 특성이 변질되면서 디즈니 애니메이션은 하위 영상문화 또는 아동적인 것으로 인식되는 원인이 됐다. 그러나 사라진 듯 보인 초기 모더니즘의 특성들은 이미지 표현에 있어 현재에도 디즈니 애니메이션에 계승되고 있다. 여전히 장르의 특성상 내러티브의 범주에서 디자인의 대상성은 중요시되지만 그 표현에 있어서는, 모더니즘 회화가 추구했던 이미지의 단순화와 과장으로 형태와 색이 줄 수 있는 심리적작용은 애니메이션 디자인에 활용되어 과거에 비해 그 특성은 더욱 강화됐다. 먼저 간단한 도형의 형태로 단순화된 모더니즘 회화의 특성은 캐릭터 디자인에 차용되고, 색은 대상의 장식이나 고증적 재현의 일차원적 목표를 넘어 카메라와 인물의 움직임으로 한 하면에서 배치가 바뀌면서 충돌 상쇄하여 관객에게 내적 경험을 유도하게 한다. 추상회화에서 색의 해방이 평면성으로 귀결된 것과 같이 캐릭터의 단순화된 개념적 색상의 사용은 캐릭터를 평면적으로 보이게 할뿐더러 이와 대조되는 공간은 더욱 평면적으로 나타나게 된다. 또한 카메라 움직임에 따라 드러나는 배경의 다중시점은 다양한 각도에서 대상의 본질을 표현하려한 모더니즘 회화를 연상시키기에 충분하다. 이러한 특성들이 초기 모더니즘 회화가 줬던 경험을 환기시킨다는 점에 입각하여 본 연구는 현대 작품들 사례를 중심으로 단순화 또는 과장된 형태, 내적표현의 색, 그리고 공간 사건의 배경의 역할을 유지하면서 움직임이 주는 경험을 20세기 초 모더니즘 회화의 특성과 비교 분석한다.

  • Despite prologed business stagnation of both international and domestic economy, hotel business as well as tourist industry has continuously been keeping growing, owing to increase of surplus income and world flowing population. During recent 4 years, growth rate of yearly mean in domestic hotels reached 9.9% and especially that of the superior class hotels 15.2%. In the composition of domestic tourist hotel's revenue, the earnings of guest rooms form 37.4%, on the other hand those of food & beverage 39.9%. This result is that our hotel business is concentrated on its interest in FOOD & BEVERAGE of which productivity per unit dimension can be increased to an unlimited extent and extent and superior class hotels strengthened in F&B are increasing in comparison with European or American hotels which are focused on guest rooms in their management. For value added rate of F&B is low as compared with increase of their earnings, they are interested in the management techniques which focus on rising the rate. As for the cost of Food & Beverage, personnel expenditure forms 36.5% and the direct materials 31.5%. Therefore how to manage personnel and materials costs which compose as much as 68% of total revenue will greatly affect net profit. We can say that an effective management technique in cost of Food & Beverage is one of the most important know-hows in hotel management. Especially management know-how for the Kitchen Department where the most of foods come out makes a great effects on various expenses, productivity and it is the achievement from hotel management. For the most of the hotel's top managers, they don't seriously take the fact that KITCHEN SYSTEM affects greatly total expenditure. This study starts from the point of recognizing the question of fundamental cause affecting tow largest cost elements incurred in Food & Beverage and trying to present an effective kitchen system. To settle the questions raised, I compared and analyzed productivity and cost of food & beverage and unit kitchen centered around superior class hotels in Seoul, which vary in Kitchen Systems. In order to attain the aforementioned study effectively purpose of this study, I compared Room-Service and Coffee-Shop Menu, flow of basic food in the kitchen, extent and result of division of labor and integration in the kitchen, scale of outlet kitchen, productivity, the turnover rate of food in store, food cost rate one another which all vary in Kitchen Systems. All these elements are compared and analyzed each other being divided into two main groups such as①. Main Production kitchen and Banquet Kitchen, and ②. coffee-shop kitchen and Room-service Kitchen. Therefore this study is to point out the problems in managing kitchens of superior class hotels which are different in systems. An effort was made to find out the better Kitchen System for superior deluxe hotels. I emphasize the followings on the proper scale of division of labor and integration of unit kitchen and a disposition plan for outlet kitchens of restaurant. First, KITCHEN SYSTEM as a sub-system of Hotel Management System is composed of sub-systems of outlet unit kitchen. Basic food materials are cooked and served for the guests while support kitchen and out restaurant kitchen interact organically each other. So Kitchen should be considered as a system composed of integrated sub-systems. Second, support and banquet kitchens should be integrated to be managed. And these unit kitchens have to be designed to be placed in the back of banquet rooms area. Third, coffee-shop kitchen and room-service kitchen should be integrated to be managed. Fourth, several unit business kitchens should be place on the same floor. Fifth, main production kitchens ought to be located near the loading duck, food store and large refrigerator. Sixth, considering the limits of supervision, duties should be adjusted as 12-20 cooks in two shifts a day for a sub-kitchen, and 18-30 cooks in three shifts a day so that labor division can be made. Last, I would like to two points for direction and task of future study. Firstly, I compare the effective income and increasing costs each other, which are incurred by increasing the use rate of the second processing materials for foods perched outside and through the results. I can find out the better points of the processing production and circulation system, and then I study this effects made on hotel kitchen system. Secondly, I can point out that more efficient kitchen system shall be established through comparing and analyzing the matter of amount of indirect costs and flow of food in different kitchen systems.

  • 플랫폼(platform) 개념은 제품 플랫폼, 거래 플랫폼에서 산업 플랫폼에 이르기까지 다양한 형태로 기업의 경영활동에 활용되어 왔다. 모든 플랫폼은 공통적으로 자주 재사용 되는 핵심과 재사용이 적고 자주 변경되는 주변부로 구성된다. 기업은 플랫폼을 사용하여 제품군, 거래, 그리고 혁신을 보다 효율적으로 개발 및 창출할 수 있다. 이러한 플랫폼은 제품을 중심으로 한 전통적 산업구조에 변화를 가져옴으로써 많은 중소기업에게 새로운 기회를 제공한다. 한국의 서비스용 로봇 산업은 협소한 시장 규모로 인해 주로 기술 중심의 중소기업으로 구성되어 있다. 이들 중소기업들은 기술개발에 성공하더라도 제품을 판매하기 위해 시장을 창출하고 확장하는데 어려움을 겪는다. 따라서 본 연구는 한국 서비스용 로봇 산업의 특성 및 문제점을 조명하고 중소기업인 로보프린트가 어떻게 서비스용 로봇 시장을 확장하고 지속적으로 성장하였는지를 플랫폼 이론을 적용하여 분석하였다. 분석결과, 로보프린트는 제품과 거래 플랫폼 개념을 적용한 것으로 나타났다. 첫째, 로보프린트는 초기에 개발한 아트봇의 핵심 기술을 기반으로 페인팅 로봇, 건물 외벽 청소 로봇 및 맞춤형 로봇을 개발하였다. 또한, 직접 로봇을 이용한 아파트 벽화 서비스를 제공하고 이를 방음벽, 지하통로, 옹벽 등 다양한 지역으로 확장하였다. 뿐만 아니라 가상현실 기술을 개발하는 등 새로운 서비스를 지속적으로 추가했다. 둘째, 로보프린트는 벽화 서비스 구매자와 벽화 디자이너를 매개하였다. 이는 벽화 서비스를 의뢰하는 구매자들이 디자이너를 탐색해야 하는 번거로움을 줄여주었고, 벽화 디자이너들에게는 벽화사업의 참여 기회를 열어주었다. 마지막으로 로보프린트는 플랫폼의 범위를 지속적으로 넓히고자 노력하였다. 내부에서만 재사용되던 로보프린트의 기술을 외부 기업과 공유하기 위해 대구광역시 '신기술 플랫폼 서비스'에 참여하였다. 뿐만 아니라 로봇을 외부 기업에 임대하여 서비스 플랫폼을 공유하고자 노력하고 있다. 본 연구는 중소기업이 다양한 플랫폼을 이용하여 시장을 창출하고 지속적으로 확장할 수 있음을 보여주어 기존 플랫폼 이론에 기여하며 실무자들에게도 유용한 시사점을 준다.

  • 소셜네트워크서비스(SNS)의 성장과 함께 다양한 형태의 SNS가 등장했다. 상호작용성, 정보 교류, 엔터테인먼트 등 다양한 이용 동기를 바탕으로 SNS 이용자 또한 빠르게 증가하는 추세이다. 그중 페이스북은 대표하는 SNS 채널로서 기업에서도 페이스북 페이지를 활용해 홍보 채널로 활용하기 시작했다. 이를 위해 운영 초기, 기업은 팬 수 확보에 나섰고 그 결과 최근 기업 페이스북 팬 수는 많게는 수백만에 이를 정도로 늘어났다. 기업의 목표는 팬 수 확보를 넘어 콘텐츠를 통해 고객에게 기업 브랜드 이미지를 재고하고, 나아가 소통하는 수단으로 활용하고 있다. 이를 평가하는 주요 수치가 바로 본 연구의 종속변수에 해당하는 페이스북의 '좋아요', '댓글', '공유', '클릭 수' 등이다. 해당 수치 달성을 위해 콘텐츠 제작에 대한 고민이 선행되어야 하는데, 본 연구에서는 콘텐츠 제작 고려 사항을 3가지로 나눠 독립변수를 구성하였다. 콘텐츠 소재, 콘텐츠 구조, 메시지 스타일 등이 페이스북의 이용자 행동에 미치는 영향을 회귀분석을 이용해 분석하였다. 종속변수의 경우, 콘텐츠상에 모든 이용자의 행동 '전체 클릭 수'로 설정하였다. 본 연구에서는 각 독립 변수를 기존 연구 문헌을 통해 정의하고, 종속변수에 미치는 영향을 분석하였는데, '전체 클릭 수'의 경우, '자사연관', '실생활 관여도', '격식 x 관여도' 등의 변수가 유의미한 영향을 갖는 것으로 나타났다. 연구 결과를 통해, 콘텐츠 목적에 따른 최적화된 콘텐츠 전략을 제시함으로써, 기업 페이스북 운영자와 콘텐츠 제작자의 운영, 제작 전략에 기여할 수 있을 것으로 보인다.
