        This study aims to classify R&D activities related to the nuclear fuel cycle using the deep learning methodology. First, R&D data of the Republic of Korea were collected from the National Science & Technology Information Service (NTIS) for the years 2021, 2022, and 2023. We use keywords such as ‘nuclear,’ ‘uranium,’ ‘plutonium,’ and ‘thorium’ to find nuclear-related R&D projects in the NTIS database. Among the numerous R&D projects found through keyword searches, overlapping and medical-related R&D projects were excluded. Finally, 495 R&D projects conducted in 2021, 430 R&D projects conducted in 2022, and 296 R&D projects conducted in 2023 were obtained for analysis. After that, Safeguards experts determine whether the R&D projects are subject to declaration under the AP. The values of the content validity index (CVI) and content validity ratio (CVR) were used to verify whether the experts’ judgments were valid. The 1,218 collected and labeled data were then divided 8:2 into training and test datasets to see if deep learning could be applied to classify nuclear fuel cycle-related R&D activities. We use the Python and TensorFlow packages, including RNN, GRU, and CNN methods. First, the collected text information was preprocessed to remove punctuation marks and then tokenized to make it suitable for deep learning. After 20 epochs of training to classify the nuclear fuel cycle-related R&D activities, the RNN model achieved 97.30% accuracy and a 5.85% error rate on the validation dataset. The GRU model achieved 96.53% accuracy and a 9.06% error rate on the validation dataset. In comparison, the CNN model achieved 94.61% accuracy and a 2.57% error rate on the validation dataset. When applying the test dataset to each model, the RNN model had a test accuracy of 83.20%, the GRU test accuracy of 82.79%, and the CNN model had a test accuracy of 85.66% for the same dataset. This study applied deep learning models to labeled data judged by various experts, and the CNN model showed the best results. In the future, this study will continue to develop an optimum deep learning model that can classify nuclear fuel cycle-related R&D activities to achieve the purpose of safeguards measures from open-source data such as papers and articles.

        In a rapidly changing environment, it is essential for companies to develop their capabilities for sustainable growth. To this end, informal learning at work plays an important role for small and medium-sized enterprises that are having difficulties in human resource development. If the GRIT of workers and the spiritual leadership of leaders are maintained at an appropriate level, the effect of informal learning will increase. This study derived the following results through a survey of workers participating in the Work-learning Dual System in Korea. First, experience and feedback among informal learning activities have a significant positive effect on competency development. Second, the higher the level of the GRIT of workers, the greater the magnitude of the positive effect of experience and feedback on competency development, showing a positive moderating effect. Third, in the case of workers with high GRIT, capacity development is strengthened as experience or feedback increases, and the higher the level of spiritual leadership, the greater the scope of reinforcement. On the other hand, it can be seen that in the case of workers with low GRIT, competency development weakens as experience or feedback increases, and the higher the level of spiritual leadership, the greater the extent of the weakening.

        This study aims to analyze the types of cognitive process required to perform vocabulary learning activities in Middle School English textbooks. For this purpose, 26 middle school English textbooks were examined, including 13 for the first year and another 13 for the second year of middle school. The results indicated that vocabulary learning activities emerged in the phase of reading, and then were categorized into pre-reading vocabulary activities and post-reading ones. Eight types of cognitive process emerged in the pre-reading phase and three types in the post-reading phase. That is, the number of vocabulary activities in pre-reading phase was larger than that in the post-reading phase. In addition, the diversity of vocabulary activities in the pre-reading phase was higher than that in the post-reading phase. Based on these results, this study suggests a new model of vocabulary learning activity in middle school English textbooks. A few implications on how to teach new words in English classrooms are discussed.

        This study investigated the relative effects of input-based versus output-based activities on the learning of English unaccusative constructions. A total of 73 high school students were randomly assigned into two experimental groups and one control group. Of the two experimental groups, the input-based input enhancement group (IE group) experienced a reading passage with the learning targets visually enhanced. The output-based dictogloss group (DG group) performed the dictogloss task with the identical passage given to IE group. The control group (CG group) did not experience the learning targets at all. Results showed that IE group statistically significantly outperformed CG group both at the immediate and the delayed posttests, while there was no significant difference between IE group and DG group. In terms of the generalizability of the learned knowledge, however, it was DG group that outperformed CG group at the immediate posttest. Again, there was no difference between IE group and DG group. More detailed findings are provided, along with some implications for English classrooms in Korea.

        This study analyzed variations of learning stress by comparing the salivary cortisol levels of students who participated in Earth Science inquiry activities. The cortisol concentrations between the pre- and post-inquiries of the sample of 34 university students, who had taken the course of ‘Basic Earth Science and Experiments’, were analyzed. The Earth Science inquiries consisted of geology and astronomy activities. The observational geology activities consisted of a session of ‘structure contours and map patterns’ and the cognitive astronomy activities consisted of a session of ‘representations of horizontal and equatorial coordinates’. These Earth Science inquiry activities were found to cause students to have anxiety, and the thought processes that these activities involved were found to cause learning stress. The variations in cortisol concentrations of students increased by 1.6±5.9 ng mL−1 after conducting observational activities in geology compared with 2.1±6.2 ng mL−1 after doing cognitive activities in astronomy. The analysis of the observational activities in the geology inquiry activities indicated that they were consistent with low levels of learning stress. Conversely, the analysis of the cognitive activities in the astronomy inquiry activities showed significant individual variations in cortisol concentrations. Furthermore, individual differences in cognitive ability were reflected in the astronomy inquiry activities. While students, who received high scores, exhibited low levels of stress in the geology inquiry activities, they showed high levels of stress in the astronomy inquiry activities. It was concluded that, in the case of students with high scores in the study, the level of learning stress increased due to the raised anxiety in cognitive inquiry activities. In contrast, students, who received low scores in the study, exhibited high levels of stress in the geology inquiry activities, and low levels of stress in the astronomy inquiry activities.

        This study examined how three task activities with receptive (R) reading, cloze (CZ) and receptive-productive (RP) integration differently lead to L2 idiom recall and retention by Korean EFL adult learners when they are enhanced with bolding, L1 glossing and three repetitions. It further looks into what features of the enhanced input tasks influence L2 idiom gains. The theories of input enhancement, receptive and productive task input are the basis for the present study. The results revealed that overall the three tasks contributed to high score of L2 idiom gains in immediate receptive, productive recall and delayed receptive retention, except delayed productive retention. There was no significant difference in idiom recall and retention by the three tasks. The descriptive analysis showed R group performed better on immediate receptive recall, while CZ group led the highest score of immediate productive recall. In terms of retention gap between immediate and delayed tests, the three tasks yielded high percentage of receptive idiom retention. The CZ task yielded the highest percentage of receptive retention but relatively low percentage of productive retention, while the R group retained most memory of productive knowledge. The results suggest some implications for effective L2 idiom teaching materials using input enhanced tasks such as bolding, L1 glossing and repetition.

        The study aims to investigate the effect of post-reading question-generation activities on Korean middle school students’ English reading abilities with respect to cooperative learning. Two groups of students read the same reading materials; however, one group as an experimental group generated questions of three types, literal, inferential, and evaluative questions, while the other group as a control group answered comprehension questions. Each group was further divided into two sub-groups by cooperative and individual learning. A statistical analysis of the recall test scores reveals a positive effect of post-reading question-generation activities and cooperative learning on English reading abilities. The reading test scores by the three question types further illustrated variations across the question types: the experimental group outperformed the control group in the inferential and evaluative questions and individual learning was detected to be more effective than cooperative learning in the evaluative questions. Interactional effects were observed between post-reading activities and cooperative learning in the literal and evaluative questions. The findings suggest question-generation activities as a beneficial post-reading task, though their effectiveness can vary by question types and learning context.

        The purpose of this study is to investigate the effects of two different types of vocabulary activities on Korean EFL learners’ vocabulary learning and perceptions. The participants of the study were 30 Korean middle school students in Seoul, and they were divided into two groups (typography and web-based authoring). The former employed the word meaning and spelling image association technique and the latter used a multimedia vocabulary authoring tool for 42 target words. The major findings of the study are as follows: (1) Both the typography and the web-based vocabulary authoring groups showed significant improvement on the posttest of vocabulary test, which indicated the equal effectiveness of the two vocabulary activities; (2) with respect to different English proficiency levels, the low-level group showed much higher improvement of the mean difference between pre and post tests than the higher group; and (3) the participants’ perceptions turned out to be more positive when they participated in creating English word spelling image than authoring multimedia vocabulary learning materials. The results suggest the beneficial effects of active student involvement in the vocabulary learning process. Pedagogical and practical suggestions are made on the effective teaching of English vocabulary in Korean classroom settings.

        This paper deals with an empirical analysis of the structural relationship among the factors such as quality management activities, organizational learning and firm performance of manufacturing corporations. The findings of the analysis are expected to make lots of contribution to manufacturing corporations establishing strategies for quality management activities and organizational learning. From the analysis, following conclusions and suggestions could be drawn: First, an analysis of the relationship between quality management activities and organizational learning showed that most activities of quality management turned out to exercise great influence upon the factors of organizational learning. This means that the activities of quality management will prompt the members of an organization to actively engage in learning activities individually, by team and organizationally, motivating them to spread such activities across the whole organization, leading ultimately to fundamental renovation of the very organization. Second, from an analysis of the relationship between organizational learning and firm performance, that is, financial and non-financial performances of a company, it was found that most factors of organizational learning have tremendous impact upon financial and non-financial performances of the company. Such result implies that decision and management of the things to be performed in the process of organizational performances are essential to determining firm performance because firm performance depend largely on the outcomes of organizational learning.
