With the advent of the "age of video" due to the simplification of video content production and the convenience of broadcasting channel operation, review videos on various products are drawing attention. We proposes RASIA, an integrated reliability analysis system based on verbal and nonverbal sentiment analysis of review videos. RASIA extracts and quantifies each emotional value obtained through language sentiment analysis and facial analysis of the reviewer in the video. Subsequently, we conduct an integrated reliability analysis of standardized verbal and nonverbal sentimental values. RASIA provide an new objective indicator to evaluate the reliability of the review video.

The purpose of this study is to classify customer experience components using Bernd H. Schmitt's Strategic Experiential Modules and explore the relevance between fashion lifestyle and customer experience components. A survey was conducted on 400 adults between the ages of 20s to 50s who had experience in sportswear stores. The results obtained are as follows. First, according to fashion lifestyle, the respondents were divided into an individuality-valued pragmatic group, a trend-oriented brand-seeking group, a fashion-interested group, and a conservative pragmatic group. Second, customer experience components were divided into sensory experience, emotional experience, cognitive experience, behavioral experience, and relational experience. Third, on analyzing the relationship between customer experience and fashion lifestyle, it was found that a fashion-interested group has the highest value in all experiences; therefore, it can be considered that the higher the interest in fashion, the more important is the customer experience. On the other hand, the conservative pragmatic group represented generally smaller values than the other three groups in all customer experiences. Fourth, there were significant differences in the customer experience components that were considered to be important depending on the fashion lifestyle type. An individuality-valued pragmatic group valued cognitive experiences, a fashion-interested group valued all experiences, and a conservative pragmatic group showed low scores in all customer experiences. The results of this study will allow companies to build more customer-friendly experiences and enable consumers to engage in satisfactory purchasing activities through better customer experiences.

Animation is a popular art in the form of enlightenment that intimately approaches people of various ages and makes them reconsider the social problems they have ignored. Therefore, this paper analyzes how the character setting and formative symbolism in "The Willoughbys" raise awareness of social agendas. The previous studies found that the modern society needs to be aware of child abuse and various types of family, and examined that color and formativeness of animation induce psychological and behavior change from the audience. The work shows emotional abuse and neglect as characters, and presents the subdivided form of the family. The rainbow symbolizes diverse family members. The agents with visual characteristics express the modern principle-based secondary perpetrator along with apathetic neighbors to urge a change in audience perception. This paper insists the value of animation when it is essential to raise public awareness prior to the construction of a welfare society and support system.

Stock prices are influenced by a number of external factors, such as laws and trends, as well as number-based internal factors such as trading volume and closing prices. Since many factors affect stock prices, it is very difficult to accurately predict stock prices using only fragmentary stock data. In particular, since the value of a company is greatly affected by the perception of people who actually trade stocks, emotional information about a specific company is considered an important factor. In this paper, we propose a deep learning-based stock price prediction model using sentiment analysis with news data considering temporal characteristics. Stock and news data, two heterogeneous data with different characteristics, are integrated according to time scale and used as input to the model, and the effect of time scale and sentiment index on stock price prediction is finally compared and analyzed. Also, we verify that the accuracy of the proposed model is improved through comparative experiments with existing models.

In this study, the author applied the service design methodology to the university library to maximize the service value provided by the university library. To this end, the 'Double Diamond Model', a service design model, was applied to the university library, and service design tools such as Persona, Customer Journey Map, and Touch Points were utilized. To reflect on the service design in the university library, the author first reviewed the literature related to the subject and researched the previous studies. Then, the issue was discovered by questionnaire surveys, interviews with users and librarians, and field investigations. Based on this, Persona and situation scenarios were derived. In addition, after synthesizing Persona's situational behavior and user's emotional change, the study visualized the Customer Journey Map and suggested service improvement plans for 11 items in 3 areas. This study is focused on the process of deriving service improvement plans rather than improving a specific service. The purpose of this study was to improve university library service and to suggest new service plans. The significance of this study is that the practical service improvement plans were applied to the university library.

This study Research is physical in times of great social and cultural influence in adolescence. In terms of spirit, growth is accelerated, developmental and situational stress is experienced in the process of finding identity, and crisis management ability is also insufficient for emotional confusion and frustration. Therefore, it has the characteristic of falling into anxiety and depression for no reason or showing strong hostility or aggression against minor stimuli. By understanding the impulsiveness, which is an important determinant of suicide in adolescents, the seriousness of suicide is recognized through the current status and reality of suicide in adolescents, and stress, which is a risk factor for suicide.It is meaningful to analyze the effectiveness of youth suicide prevention by practicing the value of life respect through life respect education programs to reduce depression and improve self-esteem as a protective factor.

Food upcycling has emerged as an effective approach to sustainably utilize the food waste generated within the food supply chain. This review article examines upcycled food with respect to its definition, consumers' knowledge and perception on it, and the process by which by-products from the food supply chain are utilized for the creation of upcycled food products. The definition of upcycled food varied among manufacturers, research institutions, and the Upcycled Food Association, depending on the specific values and objectives of each sector. This has resulted in the use of different keywords to highlight the distinctive characteristics of their respective interpretations of upcycled food. This review also summarizes the various consumer traits that can influence the awareness and acceptance of upcycled food, encompassing functional, empirical and emotional, symbolic and self-expressive, and economic benefits. Additionally, the review presents strategies to utilize by-products produced in large quantities in Korea, while also addressing the control of hazardous components to ensure biological or chemical safety and the changes in nutritional value that may occur during the utilization of these byproducts.

Background: The concept of high-impact chronic pain (HICP) has been proposed for patients with chronic pain who have significant limitations in work, social life, and personal care. Recognition of HICP and being able to distinguish patients with HICP from other chronic pain patients who do not have life interference allows the necessary measures to be taken in order to restore the physical and emotional functioning of the affected persons. The aim was to reveal the risk factors and predictors associated with HICP. Methods: Patients with chronic pain without life interference (grade 1 and 2) and patients with HICP were compared. Significant data were evaluated with regression analysis to reveal the associated risk factors. Receiving operating characteristic (ROC) analysis was used to evaluate predictors and present cutoff scores. Results: One thousand and six patients completed the study. From pain related cognitive processes, fear of pain (odds ratio [OR], 0.92; 95% confidence interval [CI], 0.87-0.98; P = 0.007) and helplessness (OR, 1.06; 95% CI, 1.01-1.12; P = 0.018) were found to be risk factors associated with HICP. Predictors of HICP were evaluated by ROC analysis. The highest discrimination value was found for pain intensity (cut-off score > 6.5; 83.8% sensitive; 68.7% specific; area under the curve = 0.823; P < 0.001). Conclusions: This is the first study in our geography to evaluate HICP with measurement tools that evaluate all dimensions of pain. Moreover, it is the first study in the literature to evaluate predictors and cut-off scores using ROC analysis for HICP.

This study was conducted to explore the factors that affect youth life satisfaction in order to find ways to increase their life satisfaction. For this purpose, we utilized data from the National Youth Policy Institute's '2021 Youth Socio-Economic Survey' to study 2,041 youth aged 18-34 as of 2021. The randomForest method was applied to explore various variables that affect youth life satisfaction. A total of 21 variables were analyzed, including demographic and socio-demographic factors and psychological and emotional factors.The results of exploring the variables affecting youth life satisfaction using randomForest are as follows. First, all 21 predictors were found to have an impact on young adults' life satisfaction. Second, the most significant impact on youth life satisfaction was found to be 'work values'. Third, it can be seen that young people's perceptions of society, such as 'political effectiveness' and 'perception of older generation', are also variables that affect youth life satisfaction. Based on these findings, the variables affecting youth life satisfaction are explained and discussion points are presented.

This dissertation discusses the formulation of a nonlinear storytelling board that preserves the contextual perspective of characters. Storytelling encompasses the director's creative intention by leveraging the interaction of various elements to construct a logical narrative that explores cause and effect. Its primary objective is to enhance viewers' empathy. Consequently, there is a pressing need for comprehensive research on differentiating storytelling from storyboarding. Moreover, the integrated approach to storytelling and storyboarding holds scholarly value in understanding the process of narrative composition and visualization. Thus, a study proposes a method for constructing nonlinear storytelling boards considering the discrete camera perspective and contextual scene continuity, ultimately contributing to visual complexity and correlation comprehension. This approach enables a careful and simultaneous consideration of the correlations that deepen cognition, including the physical, emotional, and event rhythms mentioned in Karen Perlman's theory.
