  • Human Emotion Recognition is an exciting topic that has been attracting many researchers for a lengthy time. In recent years, there has been an increasing interest in exploiting contextual information on emotion recognition. Some previous explorations in psychology show that emotional perception is impacted by facial expressions, as well as contextual information from the scene, such as human activities, interactions, and body poses. Those explorations initialize a trend in computer vision in exploring the critical role of contexts, by considering them as modalities to infer predicted emotion along with facial expressions. However, the contextual information has not been fully exploited. The scene emotion created by the surrounding environment, can shape how people perceive emotion. Besides, additive fusion in multimodal training fashion is not practical, because the contributions of each modality are not equal to the final prediction. The purpose of this paper was to contribute to this growing area of research, by exploring the effectiveness of the emotional scene gist in the input image, to infer the emotional state of the primary target. The emotional scene gist includes emotion, emotional feelings, and actions or events that directly trigger emotional reactions in the input image. We also present an attention-based fusion network, to combine multimodal features based on their impacts on the target emotional state. We demonstrate the effectiveness of the method, through a significant improvement on the EMOTIC dataset.

  • Facial expression recognition plays a significant role in understanding human emotional states. With the advancement of AI and computer vision technologies, extensive research has been conducted in various fields, including improving customer service, medical diagnosis, and assessing learners' understanding in education. In this study, we develop a model that can infer emotions in real-time from a webcam using transfer learning with TensorFlow.js and MobileNet. While existing studies focus on achieving high accuracy using deep learning models, these models often require substantial resources due to their complex structure and computational demands. Consequently, there is a growing interest in developing lightweight deep learning models and transfer learning methods for restricted environments such as web browsers and edge devices. By employing MobileNet as the base model and performing transfer learning, our study develops a deep learning transfer model utilizing JavaScript-based TensorFlow.js, which can predict emotions in real-time using facial input from a webcam. This transfer model provides a foundation for implementing facial expression recognition in resource-constrained environments such as web and mobile applications, enabling its application in various industries.

  • Acute myocardial infarction (AMI) is a multifaceted syndrome influenced by the functions of various extrinsic and intrinsic pathways and pathological processes, which can be detected in circulation using biomarkers. In this study, we investigated the secretome protein profile of induced-hypertrophy cardiomyocytes to identify next-generation biomarkers for AMI diagnosis and management. Hypertrophy was successfully induced in immortalized human cardiomyocytes (T0445) by 200 nM ET-1 and 1 μM Ang II. The protein profiles of hypertrophied cardiomyocyte secretomes were analyzed by nano-liquid chromatography with tandem mass spectrometry and differentially expressed proteins that have been identified by Ingenuity Pathway Analysis. The levels of 32 proteins increased significantly (>1.4 fold), whereas 17 proteins (<0.5 fold) showed a rapid decrease in expression. Proteomic analysis showed significant upregulation of six 14-3-3 protein isoforms in hypertrophied cardiomyocytes compared to those in control cells. Multi-reaction monitoring results of human plasma samples showed that 14-3-3 protein-zeta levels were significantly elevated in patients with AMI compared to those of healthy controls. These findings elucidated the role of 14-3-3 protein-zeta in cardiac hypertrophy and cardiovascular disorders and demonstrated its potential as a novel biomarker and therapeutic strategy.

  • The purpose of this study was to determine whether foodservice brand language localization affects consumer attitudes in terms of similar brand image recognition with an original brand. Many global foodservice companies have tried to modify their own brand identity according to local situations in order to attract more consumers. According to this study's results, consumers who similarly recognized both the original brand image and localization brand image tended to have greater purchase intention than those who did not recognize them similarly. In addition, when the original brand identity was changed to the local language, consumers more similarly conceived the original brand image and localization. And for local store marketing, foodservice companies should have a thorough marketing research plan since there can be difference results according to brand name recognition gaps or demographic characteristics. Original brand image similarity recognition by consumers affected their attitudes. In other words, the group that similarly recognized both the original brand company image and the localization brand company image tended to have greater purchase intention. Because brand language plays an important role in consumer attitudes with respect to recognizing a brand and distinguishing another brand, this study suggests that franchise foodservice companies have a local store marketing plan.

  • This study analyzes diverse factors in time poverty and quality of life in dual-earner families with preschool children that pertain to the individual, family, and occupation. Data were taken from the 17th edition of the Korean Labor and Income Panel Study developed by the Korea Labor Institute in 2014. The sample consists of 826 households who are dual-earner families with preschool children. The major findings are as follows. First, this study identified inadequacies in personal care time for dual-earner families with preschool children. Second, the results show that gender, recognition of gender role, and overall satisfaction of occupation are related to the time poverty of dual-earner families. Men are more likely to experience time poverty than women, and equal recognition of gender role and satisfaction of occupation indicate a negative relation on the time poverty of dual-earner families with preschool children. Last, quality of life in non-time-poor groups is higher than for groups who experience time poverty. Also, health state, earned income, work-family life conflict, and overall satisfaction of occupation are commonly related to quality of life in both groups. The results suggest implications for comprehensive policies to address family time issues.

  • Site-directed substitutions were made to change the Ile91 of restriction endonuclease EcoRV to either Val, Ala or Gly to identify the role of Ile91 in recognition and catalysis, since substitution of Ile91 with Leu afforded dramatic effects on the activity and properties of restriction endonuclease EcoRV. These changes alter the size of the hydrophobic side chain at position 91 and thus might have revealed the reason for the altered phenotype of Ile91Leu. However, the properties of Ile91Val and Ile91Ala mutants were much like wild type EcoRV, in both activity and metal ion preference. Ile91Gly had very little activity with either $Mg^{2+}$ or $Mn^{2+}$ as cofactors. To try to understand the unusual $Mn^{2+}$ profile of the Ile91Leu mutant, two double mutants, Ile91Leu;Asp90Asn and Ile91Leu;Glu45Met were created. Both double mutants were seriously disabled by the second amino acid change. Ile91Leu;Glu45Met had some residual activity in the $Mn^{2+}$ reaction buffer, whereas the Ile91Leu;Asp90Asn displayed no detectable activity.

  • Bakground: At our institution, We have controlled pain during vaginal delivery with epidural block since 1986. We designed a questionaire for parturients to analyze the degree of satisfaction of epidural block. Method: The self-questionaire were sent to parturients(N=200), who had epidural block to control labor pain during vaginal delivery. The questionaire covered topics dealing with motivation, fear, satisfaction and complications, of epidural block. Results: Motivation by an experienced person was 72.5%(145 parturients), fear of epidural block was 66%(132 parturients), and satisfactory response was 84%(168 parturients). Parturients who knew the role of anesthesiologist numbered 105(52.5%). Scarcely, 46 parturients displayed confidence for safety of fetus; 111 parturients experienced more than one complications. But special therapy for complications were not necessary. Conclusions: Publicity through mass-media and direct contact will improve the recognition and merit of epidural block by parturients as well as the role of the department of anesthesiology.

  • Purpose: This study examined the awareness and attitudes of parents of 5th and 6th graders toward own children smoking. Method: The participants were 766 parents of 5th and 6th graders in 11 elementary schools located in J city. Data were collected through questionnaires, which were constructed to include parents' recognition of harms to their own children cause by smoking, factors which influence their children to smoke, and parental supportive strategies to prevent smoking. Result: The percentage of parents who answered that they did not know if their children were smoking was 94.8%, while the percentage of parents who answered that they knew that their children were smoking was 3.5%. Only 30% of parents had actually spoken with their children about the dangers of smoking. The mean parental recognition of the dangers of smoking was 3.16 points. Parental strategy for preventing and prohibiting smoking with the higher mean scores included forbidding children from entering bars and nightclubs which had the highest scores at 3.55 points; forbidding the sale of cigarettes to children was next at 3.54 points. Conclusion: To prevent children from smoking, the role and attitude of parents is crucial. But the study results show that the role of parental guidance in preventing underage smoking was insufficient and under appreciated. Therefore, more systematic educational programs on preventing underage smoking are essential for parents.

  • This study examined the role of safety climate, organizational trust, job satisfaction, and organizational commitment. In addition, the study verified the mediating effect of organizational trust between safety climate, and job satisfaction and organizational commitment. Targeting population were the workers in the manufacturing sector. First, it was figured out that employees' recognition of organizations' safety climate has an effect positively on both job satisfaction and organizational commitment. Second, it turns out that individuals' safety awareness has a positive effect on the both job satisfaction and organizational commitment. Third, it was figured out that organizational trust plays a role as mediation when employees' recognition of organizations' safety climate has an effect positively on both job satisfaction and organizational commitment. Fourth, the result revealed that foreign investment company moderated the relationship between safety climate and organizational climate. Fifth, organizational trust mediates the relationship that the individuals' safety awareness are positively affected on the both job satisfaction and organizational commitment. Finally, The results of four hypotheses using intermediary variable in which organizational trust mediates the relationship between the safety climate and "work attitude" such as job satisfaction and organization commitment demonstrate significance of trust in organization in connecting safety climate and work attitude. Therefore, when trust in organization is enhanced, work attitude such as job satisfaction and organizational commitment could be improved.
