This study explores the possibility of automated scoring for scientific graph answers by designing an automated scoring model using convolutional neural networks and applying it to students' kinematics graph answers. The researchers prepared 2,200 answers, which were divided into 2,000 training data and 200 validation data. Additionally, 202 student answers were divided into 100 training data and 102 test data. First, in the process of designing an automated scoring model and validating its performance, the automated scoring model was optimized for graph image classification using the answer dataset prepared by the researchers. Next, the automated scoring model was trained using various types of training datasets, and it was used to score the student test dataset. The performance of the automated scoring model has been improved as the amount of training data increased in amount and diversity. Finally, compared to human scoring, the accuracy was 97.06%, the kappa coefficient was 0.957, and the weighted kappa coefficient was 0.968. On the other hand, in the case of answer types that were not included in the training data, the s coring was almos t identical among human s corers however, the automated scoring model performed inaccurately.

Objectives: The purpose of this study was to examine the correlation between CSEI (The Core Seven-Emotions Inventory) and MMPI-2 (Minnesota Multiphasic Personality Inventory-2). Methods: We analyzed the correlation between students' demographic characteristics, blood type, MMPI-2, and CSEI using the SPSS (Statistical Package for the Social Science) 24.0. Descriptive Statistical Analysis, independent t-test, analysis of variance (ANOVA), subsequent analysis duncan (post hoc multiple comparison), and correlation analysis were conducted. Results: 1. According to the demographic characteristics of 91 participants in this study: 60 males (65.9%), 88 unmarried (96.7%), 58 without religion (63.7%), 54 who have experienced stress in the last three months (59.4%), and 82 in their 20s (90.1%) comprised the majority. 2. As a result of verifying correlation by subfactors of CSEI, Hui (喜) showed statistically significant negative correlation with U (憂), Bi (悲), and Gong (恐). Six emotions except Hui (喜) showed statistically significant positive correlation, except for the relationship between U (憂) and Kyeong (驚). 3. Hui (喜) of CSEI had negative correlation with eight factors of MMPI-2 Clinical Scales except Pa (Paranoia) and Ma (Hypomania), whereas Bi (悲) had positive correlation with nine factors of MMPI-2 clinical scales except Mf (Masculinity-Femininity). Sa (思), Bi (悲), and Gong (恐) had similar tendency of positive correlation with six factors of MMPI-2 Restructured Clinical Scales. Conclusions: Based on the above results, we concluded that CSEI's sub factors had consistent correlations with MMPI-2. Thus, CSEI could contribute to psychiatry clinical use.

In this study, we conducted an exploratory study for designing service science as a degree program that will lead the 21st century. In the new era, the convergence of industries is accelerating and the mobility of the profession is greatly increased, so the talents to be trained in higher education will be greatly changed. We must cultivate human resources capable of creating their own jobs through competency development and cultivate talented individuals who can demonstrate creative initiative in the ecosystem where the boundaries between industries are dismantled. To this end, it is required to switch from the existing vertical majors and systems to horizontal majors, and service majors are expected to play a key role in this transition. In this study, we designed the service science degree program reflecting the changes of the new economy and reflecting the demand of the new education. The service science curriculum provides an analysis as it can award a degree as an independent major, or may serve as a sub-major or an associate major with existing majors. Service studies are expected to play the most effective role in cultivating the capabilities defined by the 21st century human resources in the World Economic Forum.

Objectives: This study was conducted to investigate the emotional characteristics of the patients within one year after stroke using the Core Seven Emotions Inventory-Short Form. Methods: It analyzed the medical records of 39 stroke patients who had visited W University hospital and completed the Core Seven-Emotions Inventory-Short Form (CSEI-S), the K-MBI, the PWI-SF, and the HADS. Patients data were analyzed by descriptive analysis, frequency analysis, the Mann-Whitney U test, and the nonparametric test of the CSEI according to the period of stroke onset in patients and Spearman's correlation analysis using the SPSS (Statistical Package for the Social Science, IBM, United States of America) Version 23.0. Results: First, in the case of depression, all subjects were in the danger group, although more than half of the joy, anger, thinking, sadness and fear were included in the normal group in the shortening of the key seven-point scale. Secondly, in measuring the social and psychological stress and hospital anxiety and depression, social and psychological stress were indicated to be a potential danger group, while anxiety and depression were shown to be a healthy group. Thirdly, the emotional characteristics were explored according to the sub-factor of the shortening of the key seven-figure emotional scale after being classified within two months, between two and six months and over six months depending on the duration of the outbreak. As a result, statistically significant, Joy was the highest score over six months and the lowest score between two and six months. On the other hand, the case of depression was depicted to be significantly lower at over six months, and was highest between two and six months. Finally, the correlations on each scale were statistically significant. Conclusions: This study provided that the CSEI-S can be used to simply to measure the emotions of patients according to the period of the onset of stroke in the clinical scene.
