On October 7, 2023, Hamas launched a large-scale surprise attack against Israel and war broke out. On this day, in addition to supplying rockets, they directly invaded Israeli territory in multiple areas using parariders and motorcycles. Considering the security situation on the Korean Peninsula, it is meaningful to consider why Israel allowed Hamas to attack and why it failed to deter the war in advance. Deterrence can only be successful if it is supported by capability, will, communication, and credibility. Although the capability and will were sufficient, and the communication through punitive deterrence had been sufficiently communicated, the failure to deter this war was problematic in terms of credibility. In order to increase deterrence against North Korea's threat, we need to improve customized extended deterrence, convey the will of both Korea and the United States to deter, and increase credibility in deterrence capabilities and execution ability.

Special judicial police officer are exercising their right to investigate areas that require expertise that is difficult for ordinary police to investigate. The fire special judicial policer are also like this, and since they investigate the specialized field of fire offenders, they require not only expertise in the firefighting field but also professional capabilities in the investigation. To achieve this, there must be improvements in the selection process for fire and special judicial police officers to secure excellent investigative personnel. There is a lack of educational facilities and training content that can systematically educate selected investigative personnel and strengthen their expertise, so improvements are needed. must also be done. Laws on controversial areas surrounding the fire and special judicial police must be reorganized and poor investigative conditions must be improved so that the fire and special judicial policer can properly perform their role.

This study propose the educational potential of an activity that solves the task of one-stroke drawing of complex figures using a drag-and-drop type educational programming language such as Scratch. The problem of determining whether a given shape is capable of one-stroke drawing is a separate problem from actually finding the path of one-stroke drawing and implementing it through programming. In particular, finding a path that allows one-stroke drawing of complex shapes with regularity and implementing it through programming requires problem-solving capabilities based on the convergence of various mathematical knowledge. Accordingly, in this study, problems related to one-stroke drawing concerning polygon-related shapes, tessellation-related shapes, and fractal shapes were presented, and the results of one-stroke drawing programming of the shapes were exemplified. In addition, the mathematical knowledge and computational thinking elements necessary for the solution of the illustrated problem were analyzed. This study is significant as a new example of the mathematics education that combines mathematics and information.

Recent developments in the use of drones on battlefields, extending beyond reconnaissance to firepower support, have greatly increased the importance of technologies for early automatic drone identification. In this study, to identify an effective image classification model that can distinguish drones from other aerial targets of similar size and appearance, such as birds and balloons, we utilized a dataset of 3,600 images collected from the internet. We adopted a transfer learning approach that combines the feature extraction capabilities of three pre-trained convolutional neural network models (VGG16, ResNet50, InceptionV3) with an additional classifier. Specifically, we conducted a comparative analysis of the performance of these three pre-trained models to determine the most effective one. The results showed that the InceptionV3 model achieved the highest accuracy at 99.66%. This research represents a new endeavor in utilizing existing convolutional neural network models and transfer learning for drone identification, which is expected to make a significant contribution to the advancement of drone identification technologies.

This study analyzes the impact of core competencies of technology innovation startups-namely technological development capability, organizational management capability, and digital transformation capability-on financial performance through the mediation of innovativeness. Previous research has focused on the non-financial performance of startups, with a lack of studies examining financial performance, which is a crucial indicator of actual business success. Therefore, an online survey was conducted targeting domestic technology innovation startups, and data from 213 responses were used for the final analysis. The results of the structural equation modeling indicated that technological development capability, organizational management capability, and digital transformation capability positively influence innovativeness. Additionally, higher levels of innovativeness were associated with improved financial performance, and innovativeness was found to play a significant mediating role between core competencies and financial performance. These findings suggest which competencies technology innovation startups should focus on to achieve financial goals.

The current society characterized by knowledge-based information technology and multiculturalism put more emphasis on problem-solving skills, creative thinking, and communication skills than any other periods did. In response to the demand of the current times, multidisciplinary, or convergence courses and majors are being created and conducted in college education, yet, with the lack of specific teaching and learning model for the convergence courses. In this context, this study aimed to examine PBL as an instructional model for the convergent approaches in classroom, since PBL has been regarded as a model for fostering the 21st century learning capabilities for student coupled with the learning principles of authentic tasks, learner-centeredness, collaborative learning. This study, after conducted a PBL course for the general art education during the summer semester of 2014, analyzed the result using data collected from students' reflective journals, in-depth interviews, and SNS posts among the students. The result presented students' enhanced self-respect, increased interest in their learning and communication skills, and their recognition of the value on diversity and empathetic attitudes toward each others. In conclusion, PBL showed its potential as an alternative instructional model for the multidisciplinary and convergent learning in college education.

Network security performance evaluation is a complex and diverse system environments, a single, specific performance measurements alone performance evaluation measure itself and the meaning of the reliability of the evaluation results do not limit the number of days only. In this paper, we propose a method to measure the security features of security, QoS measurement techniques using MOS satisfaction. MOS(Mean Opinion Score) Rating specifications for network security, QoS satisfaction and how to operate the development and operational model for future customer's satisfaction for information systems that can be used to evaluate the QoS measurement/analysis be utilized in the field. Objectified in the form of standards and performance measurement system provider (supplier development) and consumers(users) all the results available so that how to develop a system. Development is the development of information security features, the performance of these two features networking capabilities and a comprehensive evaluation of a three-gaeyoungyeok Correlating performance measurement methodology. Systematic measurement environment designed using the proposed methodology of this study, when the operating system is on the satisfaction of the security, QoS can be calculated. Forward In addition, a variety of performance metrics and performance measurement methods by extending the network security system satisfaction rating upgrade by the way will be.
