  • Quantitative risk levels must be presented by analyzing the causes and consequences of accidents and predicting the occurrence patterns of the accidents. For the analysis of marine accidents related to vessel traffic, research on the traffic such as collision risk analysis and navigational path finding has been mainly conducted. The analysis of the occurrence pattern of marine accidents has been presented according to the traditional statistical analysis. This study intends to present a marine accident prediction model using the statistics on marine accidents related to vessel traffic. Statistical data from 1998 to 2021, which can be accumulated by month and hourly data among the Korean domestic marine accidents, were converted into structured time series data. The predictive model was built using a long short-term memory network, which is a representative artificial intelligence model. As a result of verifying the performance of the proposed model through the validation data, the RMSEs were noted to be 52.5471 and 126.5893 in the initial neural network model, and as a result of the updated model with observed datasets, the RMSEs were improved to 31.3680 and 36.3967, respectively. Based on the proposed model, the occurrence pattern of marine accidents could be predicted by learning the features of various marine accidents. In further research, a quantitative presentation of the risk of marine accidents and the development of region-based hazard maps are required.

  • The purpose of this study is to develop and validate a scale for measuring digital literacy by identifying the factors consisting of digital literacy and extracting items for each factor. Preliminary items for the Delphi study were developed through the analysis of previous literature and the deliberation of the research team. As a result of two rounds of the expert Delphi study, 65 items were selected for the main survey. The validation of the items was carried out in the process of exploratory and confirmatory factor analyses, reliability test, and criterion validity test using the data collected in the main survey. As a result, a 4-factor structure composed of 31 questions(factor 1: digital technology & data literacy- 9 questions, factor 2: digital content & media literacy- 8 questions, factor 3: digital communication & community literacy- 9 questions, factor 4: digital wellness literacy - 5 questions) was confirmed. Also, the goodness of fit indices of the model were found to be good and the result of reliability test revealed the scale had a very appropriate level of Cronbach's alpha(α=.956). In addition, a statistically significantly positive correlations(p<.001) were found between digital literacy and internet self-efficacy and between digital literacy and self-directed learning ability, which were predicted in the existing evidence, therefore the criterion validity of the developed scale was secured. Finally, practical and academic implications of the study are provided and future study and limitations of the study are discussed.

  • Je Baek-seok, who is well versed in poetry, calligraphy, painting, and sculpture, has established himself as the most outstanding painter and pavilion in the history of modern and contemporary Chinese art. During the Ming and Qing Dynasties, the art of the pavilion was developed greatly during the enlightenment period, with the emergence of many masters of the pavilion, including Jeonggyeong, Hwanghwangseokyeo, Oyangji, Jo Ji-gyeom, Hwang Mok-bo, and Oh Chang-seok. Je Baek-seok formed an original ritual under this social background. Je Baek-seok's tactics were formed by imitating works from the Hanwi period, and he harmonized Jin Kwon, Sopan, and Janggunin while using the penmanship of the Cheonbal Shinchambi based on the "Sasam Gongsanbi." In addition, by boldly using the Danipdo method, it is possible to use the human face as much as possible while fully exhibiting the artistry of calligraphy and adding to the atmosphere of gold stone. This paper mainly analyzed and reviewed the process of Je Baek-seok's transcription transformation and humanities practice from two aspects. First, it is planned to summarize the process of Je Baek-seok's transformation into a Jeonseo. Second, Je Baek-seok's humanities practice was analyzed. This paper will further understand Je Baek-seok's humanistic ideas and practical search by clarifying the originality of Je Baek-seok's engraving art with examples of Je Baek-seok's works, and it is believed that this will provide future scholars with learning paths and rich experiences.

  • This research investigated category-based feature inference when category features were connected in common cause and common effect causal networks. Previous studies that tested feature inference in causal categories showed unique inference patterns depending on causal direction, number of related features, whether the to-be-inferred feature was cause or effect, etc. However, these prior studies primarily focused on inference pattens that arise from causal relations, and few studies directly explored how the effects of causal relations vary depending on causal strength. We tested feature inference in common cause (Expt. 1) and common effect (Expt. 2) causal categories when casual strengths were either strong or weak. To this end, we had participants learn causal categories where features were causally linked and then perform feature inference task. The results showed that causal strengths as well as causal relations had important impacts on feature inference. When causal strength was strong, inference for common cause feature became weaker but that for the common effect feature became stronger. Moreover, when causal strength was strong and common cause was present, inference for the effect features became stronger, whereas the results were reversed in common effect networks. In particular, in common effect networks, casual discounting was more evident with strong causal strength. These results consistently demonstrate that participants consider not only causal relations but also causal strength in feature inference of causal categories.
