A 2(pedagogical agent: with vs. without) × 2(on-screen text: with vs. without) between-subject design was used in this study to investigate the effects of pedagogical agent and redundant on-screen text on video learning. In the case of the educational video without redundant on-screen text, there was no difference in social presence, satisfaction, and intention to continue learning regardless of the presence of a pedagogical agent. However, when the educational video contained redundant on-screen text, participants who watched educational video with pedagogical agent perceived higher social presence, satisfaction and intention to continue. In terms of academic achievement, no difference was found whether redundant on-screen text was contained or not. It supports some of the previous studies on the reverse-redundancy effects, suggesting that the inclusion of redundant text does not necessarily cause the reduction of learning outcomes. Video learning shows a higher dropout rate than face-to-face learning. Therefore, it is particularly important to understand how to strengthen interactions with learners and motivate them to keep themselves engaged in learning. This study discussed whether pedagogical agent and on-screen text are factors that induce continuous participation of learners in video learning.

Recently, drones have been used as a major means of attack drones in major wars around the world, and it seems likely that they will evolve into game changers in the future. Recently, drones have been used as a major means of attack drones in major wars around the world, and it seems likely that they will evolve into game changers in the future. In the major wars of the 21century, attack drones are used for precision fire-guided or self-destruct attacks, For the purpose of cognitive warfare, its territory is expanding not only to land and air, but also to sea and water. These attack drones will perform multi-domain operations, and for this purpose, the level of autonomy will be improved and High-Low Mix We will continue to develop by strengthening concept-based scalability. North Korea has also been making considerable efforts to operate attack drones for a long time, and activities such as third-country-level self-explosive drones, artificial intelligence-based clustered self-explosive drones, and self-destructive stealth unmanned semi-submersible are expected. In addition to North Korea's provocations and attacks, it is hoped that there will be a need for active follow-up research on our military's countermeasures and utilization plans.

After participating in the Second Boer War in 1899, the Australian Army participated in world wars such as World War I, World War II, the Korean War, and the Vietnam War. To overcome the decline in the social recognition of soldiers and the continuous shortage of troops caused by the protracted war, the status and role of female personnel were expanded. The use of female manpower, which started as medical support during the Second Boer War, expanded to combat support missions such as communications, maintenance, driving, secret document management, and radar surveillance during World War II. After the Vietnam War, the Chiefs of Staff of the Australian Army, Navy and Air Force established a committee to expand women's participation in the military, improved service conditions for female personnel and supplemented regulations so that they were treated as soldiers, not women, and reached a turning point in expanding the role of female personnel in the Australian military. As a result, all combat positions, including special forces, were opened to women in 2014, and a plan was established to increase the proportion of women in each service by 2030. As a result, all combat positions, including special forces, were opened to women in 2014, and the Australian Armed Forces set a plan to increase the proportion of women by 2030. Like the Australian military, South Korea is also experiencing a demographic cliff and shortage of troops due to the continuing low birthrate problem. Through the history and current state of the use of female personnel in the Australian military, we would like to draw implications for the direction our military should go.

This study investigates why Korean English speakers misunderstand the English article system, which article Korean EFL learners use more accurately in their English writings, and implications for English writing instruction from Korean EFL learners' utterances. There have been numerous studies on the acquisition of English article system by non-native English speakers. Those studies agree that acquiring English articles is difficult for learners of English as a second language. As a result, in this study, many English learners use the definite and indefinite articles a/an. Many wrote articles from their writings, and occasionally, errors of excessive use of definite articles occurred. Through this, this paper investigates how a Korean English learner whose native language has no articles chooses the English article system in speech. It is based on the elicited production of the Korean English learner and suggests some implications for teaching English writing in the classroom. When English instructors teach Korean English learners to write English, it is more important than anything else to practice the correct usage of definite articles or indefinite articles.

Object detection technology that accurately recognizes the road and surrounding conditions is a key technology in the field of autonomous driving. In the field of autonomous driving, object detection technology requires real-time performance as well as accuracy of inference services. Task offloading technology should be utilized to apply object detection technology for accuracy and real-time on resource-constrained devices rather than high-performance machines. In this paper, experiments such as performance comparison of task offloading, performance comparison according to input image resolution, and performance comparison according to camera object resolution were conducted and the results were analyzed in relation to the application of task offloading for real-time object detection of autonomous driving in resource-constrained devices. In this experiment, the low-resolution image could derive performance improvement through the application of the task offloading structure, which met the real-time requirements of autonomous driving. The high-resolution image did not meet the real-time requirements for autonomous driving due to the increase in communication time, although there was an improvement in performance. Through these experiments, it was confirmed that object recognition in autonomous driving affects various conditions such as input images and communication environments along with the object recognition model used.

This study aimed to investigate factors influencing depressive symptoms among middle-aged women based on walking and nonwalking. The participants of the study were 56,007 women aged 40-64 years. A complex sample statistical analysis was conducted. Notably, 48.9% of middle-aged women were in the walking group and 51.1% were in the nonwalking. In the nonwalking group, relative to the walking group, more people had high school diploma as their highest level of education, and were 40-49 years old, unemployed, and public assistance recipients than in the walking group. In addition, in the nonwalking group, more people had sleeping durations of less than 7 hours, perceived stress, and depressive symptoms than in the walking group. Factors influencing depressive symptoms were identified as less than 7 hours of sleeping duration and high perceived stress in both the walking and nonwalking groups, and the degree of influence was higher in the walking group than in the non-walking group, suggesting than further studies are needed to identify the cause. The results confirmed that perceived stress and depressive symptoms in middle-aged women could be reduced by walking. Therefore, if middle-aged women continue to engage in walking practices appropriate for them, it will enhance their walking rate, reduce stress, and improve their depressive symptoms.

With the development of IT, mobile apps and the expansion of contactless services due to COVID-19, "smart orders" have recently been activated in the food and beverage service. Even in recent years, when sales have declined, the number of orders made by smart orders has been steadily increasing, and this ordering method can accumulate customer data, enabling effective customized services in the future. In the present study, satisfaction with smart orders and continuous use intention were studied based on the technology acceptance model (TAM). And it focused on whether there is a difference in personality when using smart orders. For this purpose, a survey was conducted on 317 smart order users, and the hypothesis was verified by structural equation model analysis. Perceived benefits had a significant effect on satisfaction; also, satisfaction had a significant effect on continuous use intention. There is a significant disparity between introvert and extrovert type. As a consequence, the introverted type has a greater intention to perceive usefulness of smart orders and continuously use them. These results suggest that the customer's personality type should be considered in future customer customization strategies.

The purpose of this study is to propose a method for evaluating the similarity of Show gardens using Deep Learning models, specifically VGG-16 and ResNet50. A model for judging the similarity of show gardens based on VGG-16 and ResNet50 models was developed, and was referred to as DRG (Deep Recognition of similarity in show Garden design). An algorithm utilizing GAP and Pearson correlation coefficient was employed to construct the model, and the accuracy of similarity was analyzed by comparing the total number of similar images derived at 1st (Top1), 3rd (Top3), and 5th (Top5) ranks with the original images. The image data used for the DRG model consisted of a total of 278 works from the Le Festival International des Jardins de Chaumont-sur-Loire, 27 works from the Seoul International Garden Show, and 17 works from the Korea Garden Show. Image analysis was conducted using the DRG model for both the same group and different groups, resulting in the establishment of guidelines for assessing show garden similarity. First, overall image similarity analysis was best suited for applying data augmentation techniques based on the ResNet50 model. Second, for image analysis focusing on internal structure and outer form, it was effective to apply a certain size filter (16cm × 16cm) to generate images emphasizing form and then compare similarity using the VGG-16 model. It was suggested that an image size of 448 × 448 pixels and the original image in full color are the optimal settings. Based on these research findings, a quantitative method for assessing show gardens is proposed and it is expected to contribute to the continuous development of garden culture through interdisciplinary research moving forward.
