VR(Virtual Reality), which provides realistic services in virtual reality, provides a similar experience using a Head Mounted Display(HMD) device. When the HMD device is worn, it can not recognize the surrounding environment and it is easy to analyze the input pattern of the user with the Shoulder Surfing Attack(SSA) when entering the Personal Identification Number(PIN). In this paper, we propose a method to safeguard the user's password even if the hacker analyzes the input pattern while maintaining the user's convenience. For the first time, we implemented a new type of virtual keypad that deviates from the existing rectangle shape according to the VR characteristics and implemented the lock object for intuitive interaction with the user. In addition, a smart glove using the same sensor as the existing input devices of the VR and a PIN input method suitable for the rotary type are implemented and the safety of the SSA is verified through experiments.

Purpose : The purpose of this study was to examine the effects of applying occupational therapy that uses motion recognition on the physical self-efficacy, visual-motor integration ability, and play skills of children who have neurodevelopmental disorder before and after treatment. Methods : This The study chose 16 children with neurodevelopmental disorder as research subjects who were randomly and evenly allocated into an experimental group and a control group. The experiment followed a pretest-posttest design. As an intervention, the experimental group received motion recognition-based occupational therapy and a separate sensory integration program. The control group only participated in the separate sensory integration program. The eight-week experiment duration included 24 intervention sessions where the a 50-minute session was implemented three times a week for eight weeks. To compare the physical self-efficacy, visual-motor integration ability, and play skills before and after the intervention, measurement tools including the Physical self efficacy, Beery VMI-6, and Penn interactive peer play scale were used. All measured variables were analyzed and expressed as mean, standard deviation and percentage. Results : The motion recognition-based occupational therapy demonstrated a significant effect on improving the physical self-efficacy, visual-motor integration ability, and play skills of the experimental group. The intervention also caused a significant difference between the experimental group and control group in terms of the physical self-efficacy, visual-motor integration ability, and play skills. Conclusion : We confirmed the possibility motion recognition-based occupational therapy could be effective in improving the physical self-efficacy, visual-motor integration ability, and play skills for patients who have neurodevelopmental disorder. Based on the study result, further future studies are expected based on this study result that prove the application effect of the motion recognition-based occupational therapy using disabled and non- disabled children as subjects are expected in the future.

Recently a drama that features a lawyer with autism spectrum disorder has attracted a lot of attention, raising interest in the difficulties faced by people with autism spectrum disorders. If the Autism spectrum gets detected early and proper education and treatment, the prognosis can be improved, so the development of the treatment is urgently needed. Drugs currently used to treat autism spectrum often have side effects, so Digital Therapeutics that have no side effects and can be supplied in large quantities are drawing attention. In this paper, we introduce 'AEmotion', an application and a Digital Therapeutic that provides emotion and facial expression learning for toddlers with an autism spectrum disorder. This system is developed as an application for smartphones to increase interest in training autistic children and to test easily. Using machine learning, this system consists of three main stages: an 'emotion learning' step to learn emotions with facial expression cards, an 'emotion identification' step to check if the user understood emotions and facial expressions properly, and an 'expression training' step to make appropriate facial expressions. Through this system, it is expected that it will help autistic toddlers who have difficulties with social interactions by having problems recognizing facial expressions and emotions.

The current situation of ports and related industries is transitioning from quantitative growth in increased cargo volume and expansion of port facilities to qualitative growth in the role of ports through the creation of high value-added. Ports are now recognized as playing an important role in economic growth and development by generating high value-added, not just by increasing the amount of cargo and expanding port facilities. This study evaluated the importance of factors affecting the improvement of the Busan Port's marine equipment industry by using the Analytic Hierarchy Process(AHP) to derive the priority of improvement measures by factor and evaluate the importance of factors affecting the marine equipment industry. The factors that should be considered when selecting improvement measures for the marine equipment industry were selected as four factors: strengthening price competitiveness, increasing government and local government interest, strengthening promotion, and establishing a global network. The main sub-factors were composed of eight detailed evaluation factors by selecting two factors for each layer. The analysis was designed by dividing the factor hierarchy for selecting improvement measures for the marine equipment industry into three levels and creating survey questions for pairwise comparison. The priority of the analysis results using AHP showed that the factor with the highest priority was strengthening price competitiveness, followed by increasing government and local government interest, establishing a global network, and strengthening promotion. According to the analysis results for the second-level sub-factors, among the factors for strengthening price competitiveness, low distribution costs and storage costs were considered most important, followed by avoiding excessive competition among marine equipment companies. Among the factors for increasing government and local government interest, improving customs procedures and tariff refund procedures were considered most important, followed by strengthening incentives from the government and Busan City. Among the factors for establishing a global network, promoting large-scale marine equipment companies was considered most important, followed by actively participating in international marine equipment-related associations. Among the factors for strengthening promotion, active use of the Internet was considered most important, followed by holding domestic and international exhibitions. Based on this study, we hope to help activate Busan Port's market by enhancing its competitiveness through revitalizing its marine equipment industry, generating water traffic, and creating new value-added.
