  • Happiness research has primarily been conducted based on the American model of happiness. The agentic concept of happiness in the West emphasizes the positive feeling state stemming from individual achievement and positive interpersonal relationships. However, previous studies on lay theories of happiness in other East Asian countries, such as China and Japan, have suggested that these meanings of happiness differ from those of the Western cultural context. The present study examined the lay theory of happiness among Koreans using qualitative and quantitative approaches. Furthermore, the authors compared the Korean model of happiness with that of the Japanese and Americans from Uchida and Kitayama (2009). The findings from the present research indicate that the Korean model of happiness involves both positive and negative states and consequences of happiness, unlike the uniformly positively connoted happiness in Western cultural contexts. The paper concludes with a discussion of the implications of the current findings on happiness research in the Korean culture.

  • This paper proposes a method to improve the performance of ship identification through lofargram analysis of ship noise by applying the Hough Transform to a Convolutional Neural Network (CNN) model. When processing the signals received by a passive sonar, the time-frequency domain representation known as lofargram is generated. The machinery noise radiated by ships appears as tonal signals on the lofargram, and the class of the ship can be specified by analyzing it. However, analyzing lofargram is a specialized and time-consuming task performed by well-trained analysts. Additionally, the analysis for target identification is very challenging because the lofargram also displays various background noises due to the characteristics of the underwater environment. To address this issue, the Hough Transform is applied to the lofargram to add lines, thereby emphasizing the tonal signals. As a result of identification using CNN models on both the original lofargrams and the lofargrams with Hough transform, it is shown that the application of the Hough transform improves lofargram identification performance, as indicated by increased accuracy and macro F1 scores for three different CNN models.

  • As a core area of the new computing paradigm, the Ubiquitous Sensor Network Technology utilizes a wireless sensor networking which can be applied to the Context Information Monitoring System. When the technology is used in a poor user-environment for monitoring purposes, it can cost-effectively gather the context data on real-time basis, analyze the information gathered, effectively response to the user situation, and execute orders to create environmental factors desired by the user. This study structures a system able to monitor information in regards to a user-environment based on wireless-node sensor technology coupled with the Ubiquitous Sensor Network Technology. In this paper, the protocol in which it manages the wireless sensor network as the zone based by using the management protocol standardized at the smart home with a profile is proposed. The proposed system requires a minimal collection of data without continuous monitoring. Monitoring periodically, it can sense the user-environment more efficiently than the existing monitoring technologies based on the wire-communication technology.

  • TRIZ was developed and refined in the Soviet Union between 1946 and 1985 by Genrich Altshuller. Its primary application has been for solving inventive problems in the areas of engineering. But, recently the elements of TRIZ began to be applied non-technical areas by Darrell Mann. TRIZ theroy was brought into South Korea in 1995 and it is used by the LG, SAMSUNG, POSCO. TRIZ is simply not the tool for technical problem solving, covering many areas of comprehensive approach is being recognized. TRIZ is a methodology for defining problem, finding root cause through RCA(Root cause analysis), defining technical contradiction and physical contradiction. TRIZ overcomes contradiction and purses problem solving method through innovation. TRIZ is a problem solving method in this study using the principles of non-technical fields applied to the improvement of the logistics area study. The method to overcome contradiction is 40 principles. It is possible to generate idea by using 40 principles. This study was applied to logistics field of non-technical area by using TRIZ principle.

  • As the main carrier of information, digital image is becoming more and more important. However, with the popularity of image acquisition equipment and the rapid development of image editing software, in recent years, digital image counterfeiting incidents have emerged one after another, which not only reduces the credibility of images, but also brings great negative impacts to society and individuals. Image copy-paste tampering is one of the most common types of image tampering, which is easy to operate and effective, and is often used to change the semantic information of digital images. In this paper, a method to protect the authenticity and integrity of image content by studying the tamper detection method of image copy and paste was proposed. In view of the excellent learning and analysis ability of deep learning, two tamper detection methods based on deep learning were proposed, which use the traces left by image processing operations to distinguish the tampered area from the original area in the image. A series of experimental results verified the rationality of the theoretical basis, the accuracy of tampering detection, location and classification.

  • Despite the great significance we attach on culture, only a handful of researches focus on the characteristics and practices of cultural journalism. This study has aimed to unravel the changes in the trajectory of cultural journalism of Korean major newspapers, through content analysis and qualitative interpretation of the cultural contents they report. The results show that the number of cultual items have decreased compared to that of 10 years ago, although the entire number of pages has meanwhile increased. News items focused on 'products(advertisement)' and 'life(style)' have increased, whereas those on 'knowledge refined' and 'leisure entertainment' have decreased. 'Critique review commentary', 'academics' and 'performance exhibition art music' items turn out to have decreased significantly; soft contents such as mass culture, tourism, fashion and beauty, on the other hand, have increased considerably. Moreover, the demographic characteristics of news contributors remain almost the same, except that the proportion of ordinary readers/audience has slightly increased. Similarly, although there were no difference regarding the sources of direct quotation, the frequency of quotes from ordinary readers has increased. Consequently, these results imply how the cultural journalism of Korean newspapers are limited in encompassing diverse types of content, differentiating constitution, and presenting critical viewpoints.

  • This study systematically analyzed computer-based driving intervention programs for seniors, to provide the academic background for driving intervention for seniors. Articles published from January 2009 till December 2018 were researched and analyzed. 'PubMed, Google Scholar, and Science Direct' were used to search articles published overseas, and 'RISS, KERIS, and KISS' searched for articles published in Korea. Based on the inclusion and exclusion criteria, totally 359 papers were retrieved, and 10 articles were finally analyzed; 8 articles (80%) were evidence level I, and 2 articles (20%) were evidence level III. Amongst the computer-based interventions, driving simulators (70%) were the most common, followed by two video image training (20%) and one Nintendo Wii program (10%). In most studies, driving simulators trained the cognitive and visual abilities of seniors and enhanced their abilities to cope with risk situations under various simulated circumstances. Other interventions were also reported to have a positive effect. For evaluating elderly drivers, the driving performance evaluation using a driving simulator was the most common; in addition, evaluations of attention, space-time ability, cognitive function, risk perception, depression and anxiety were also commonly used. We believe that it is appropriate to employ computer-based driving intervention programs for seniors to train and evaluate various domains. We expect that these interventions can be used as an effective tool for safe driving.

  • The purpose of this study was to identify the emotional and stress factors of the stroke victims living in the community and to investigate the effect of these factors on the level of social participation. Data collection collected data on the level of emotional awareness, stress, and social participation in welfare centers, public health centers, and stroke disabled people using community services. The level of social participation according to general characteristics was analyzed by descriptive statistics and one-way ANOVA. Emotional factors, stress factors, and social participation levels were analyzed by pearson correlation analysis and multiple regression analysis. As a result, there were no statistically significant factors in the sub-domains of emotional factors that affect social participation performance and satisfaction. In the sub-areas of stress factors, personal internal stress and interpersonal stress were statistically significant variables. The explanatory power showed social participation accomplishment was 34% and satisfaction was 33%. Therefore, various approaches should be made considering stressful factors to achieve rehabilitation into the local community, and additional research is needed to identify psychosocial variables that affect social participation.

  • In an era where AI artificial intelligence converges into each field, design of AI-CARE function and UI UX design are in the spotlight. The application of shape design and the trend of color are important for visual effects to match new features. In this paper, we would like to use this to present an example of the arrangement and application of form trends and to present design directions. In the introduction, the latest design environmental factors were analyzed and studied in the direction of the new proposal. In the text, the design direction and consideration of the design in the planning were studied by separating the functional design form, and the direction of the design work was presented. At the stage of form and color, a plan was proposed to match the flow of minimalism, universal design, and affordance design. A study method based on case practice is a consideration of how to consider content on shapes and colors specialized in the partial design work, and proposed to enable graphic production of new areas of UI UX in content images to be feasible. Through this study, the design direction and planning of the derivative method of shape and color was reached by suggesting design directionality and validity for each AI CARE bed PART.

  • This study empirically identified and sought implications for the degree of desire by film crews to participate in overseas production and the factors affecting them, based on the recognition that the active participation of skilled film crews in overseas production and joint ventures can be an alternative to the poor treatment of domestic film industry sites and the reduction of job losses due to problems with career barriers. In order for respondents to verify research questions, binomial logistic and marginal effects analysis using SPSS and STATA, the data obtained by surveying 402 film crews operating in various areas. The notable findings are as follow: First, about 65%(263 people) of the respondents expressed their desire to participate in overseas activity, indicating that a considerable number of film crews are looking forward to opportunities with overseas productions. Second, major factors that have a positive effect on film crews' need to participate in overseas activities have been found to be professionality, artistic identity, Korean Wave persistence, and career barriers. In other words, the higher the professionality, the more clearly the identity of the artist, the more positive expectations of the possibility of the Korean Wave continuing, and the more serious the problem of career disability, the clearer was the desire to participate in overseas production and joint-work activities.
