On December 26, 2022, North Korea's drone provocation resumed for the first time in eight years. The threat covered not only the Seoul metropolitan area but also the no-fly zone for the presidential office's security, and the South Korean military's response to it is not appropriate, which is a major controversy. In the midst of this, problems caused by the prohibition of small drones' flight and illegal intrusion into restricted areas are increasing in Korea, and the threat is becoming a reality, such as being used for terrorist attacks abroad. In this paper, the concept of "Counter-Drone" and related technologies were considered for these drone threats, and implications were derived through domestic and overseas small drone threats, and the direction of development of the Counter-Drone system was presented. North Korea's drone threat is expected to be more diversified, massified, and advanced, resulting in bolder attacks and provocations. Therefore, the South Korean military should push for early powering of the integrated control system and the conter drone system, joint and military cooperation in response to the threat of small drones, and the ability to carry out joint operations between South Korea and the U.S.

Objective : This study aimed to develop a Comprehensive Oro-Facial Function Scale (COFFS) that can evaluate oro-facial function in patients with dysphagia. Methods : To verify the item composition and reliability of the COFFS, preliminary items were collected by selecting and analyzing four previous studies, and the Content Validity Ratio (CVR) was derived through a second survey of experts. Cronbach's 𝛼 was calculated for the internal validity of the evaluation items, and the test-retest reliability and inter-rater reliability were calculated using the internal classification coefficients (ICC). Results : The content validity ratio of all items was 0.67; in the case of Cronbach's 𝛼 value for each domain, 0.849 for communication domain, -0.224 for the oro-facial structure and shape, 0.831 for the ability to perform orofacial movements, and 0.946 for mastication and swallowing function. The test-retest reliability was 0.974 and the inter-rater reliability was 0.937, showing high reliability. Conclusion : In this study, the evaluation tool of COFFS was finally selected from 34 items in four areas and developed on a 3-5 point scale according to the evaluation items. In future studies, additional research is needed to prove its validity through correlation with other evaluation tools that measure oro-facial function.

Mass transit information can contribute many benefits to users. Especially, transportation information technology is developing highly with information technology in Korea recently. Hereafter, it is expected to give customized transportation information to users individually with the advent of ubiquitous age in earnest. This public transportation information service can be realized by path finding algorithm in public transportation networks including travel and transfer attributes. In this research, constraints are constructed with the primary facts influencing users. Moreover, the method reducing user's path finding condition arbitrarily is proposed by making the maximum value as variables. In this study, transfer frequency, total travel time, seat confirmation, transfer time and travel time become constraint condition based on k path finding algorithm considering service time constraint condition. Moreover, case study about user customized transfer information is performed in Seoul and metropolitan subway networks.

This study aims to look for the proper directions of following and developing Gyeonggi sinawi dance in the fashion of Kim Sukja by closely examining its kinds and patterns. First, its characteristics and education reality were investigated. Second, the seven kinds of Gyeonggi sinawi dance Kim Sukja allegedly handed down (according to the 121st Report of the Intangible Cultural Assets) were concretely examined. Third, the composition of each dance pattern was studied. Fourth, various beats used in Gyeonggi sinawi dance were revealed. The late Kim Sukja had outstanding artistic talent and ability in Gyeonggi sinawi dance movements, musical composition, gayageum accompanied singing, and pansori episodes. Behind her were master singer Kim Seokchang (grandfather), father Kim Deoksun (belonging to Hwaseong Artist Board), shaman-mother Jeong Gwiseong, and great dancer Jo Jinyeong. Kim sukja's seven Gyeonggi sinawi dance types were bujeong nori, teo beollim, jinsoe, jeseok, kkaekkeum, ollimchae, and dosal puri (designated as Important Intangible Cultural Asset in 1990). Such beats as seopchae (dosal puri), mori, bal ppeodeurae, bujeong nori, ollimchae, jinsoe, and teo beollim (ban seoreum) were mainly used in Gyeonggi sinawi dance. In sum, Kim Sukja's dance was more than an individual's dance to represent the cultural types and life at that time in Gyeonggi-do and be a very important academic historic material. Therefore, it is the responsibility of the present generation to hand down and develop such invaluable traditional cultural materials.

The present study purposed to examine empirically the effects of animosity against a product's country of origin on product evaluation, attitude and purchase intention. For this study, we conducted an experiment of 316 university students in the Metropolitan area. The results of this study suggest that the negative influence of animosity against the country-of-origin on attitude and purchase intention was higher for low-typicality products than for high-typicality ones. This result suggests that the negative influence of animosity against a specific country is not equal among all products from the country, but can vary among the products. For products manufactured in a country other than the country-of-origin, the negative influence of animosity against the country-of-origin did not decrease. This result means that, even for multinational products, animosity against the country-of-origin can have a negative influence on the consumers' response to the products. Based on major findings of this study, both academic and practical issues are discussed. Suggestions for future studies are provided.

Objective : This study was conducted to confirm the effect of the oral motor facilitation technique (OMFT) on oral motor function in stroke patients. Methods : This study was conducted on 72 stroke patients with dysphagia were included. Thirty-six patients were randomly assigned to the experimental and control groups were randomly classified into 36 patients each using a random table, and a two-group pre-post test was designed. The experimental group underwent OMFT, and the control group underwent traditional dysphagia therapy for 30 min, once a day, 5 times a week for 4 weeks, for a total of 20 sessions. The Comprehensive Orofacial Function Scale (COFFS) was used to evaluate oral motor function. Repeated-measures analysis of variance (ANOVA) was performed to confirm the effect of the period, and an independent t-test was performed to analyze the difference in change between the two groups. Results : Total COFFS scores improved in both groups. The experimental group showed significant changes in mandibular and lip movements, cheek blows, and tongue movements. In addition, there were significant differences depending on the intervention period in terms of masticatory distribution, food spillage, swallowing of solid and liquid foods, and voice changes. There were significant differences in the mandibular opening and closing categories between the two groups. Conclusion : OMFT is effective in improving oral motor function in stroke patients with dysphagia and can be used as basic evidence in clinical practice.

Machine learning (ML)-based cavity detection using a large amount of survey data obtained from vehicle-mounted ground penetrating radar (GPR) has been actively studied to identify underground cavities. However, only simple image processing techniques have been used for preprocessing the ML input, and many conventional seismic and GPR data processing techniques, which have been used for decades, have not been fully exploited. In this study, based on the idea that a cavity can be identified using diffraction, we applied ML-based diffraction separation to GPR data to increase the accuracy of cavity detection using the YOLO v5 model. The original ML-based seismic diffraction separation technique was modified, and the separated diffraction image was used as the input to train the cavity detection model. The performance of the proposed method was verified using public GPR data released by the Seoul Metropolitan Government. Underground cavities and objects were more accurately detected using separated diffraction images. In the future, the proposed method can be useful in various fields in which GPR surveys are used.

The study aims to synthesize the discussion of the innovation district and suggest an alternative to the governance system of the innovation district. Cluster policies that focus on industrial specialization, networking, value chains, and industrial ecosystems have shown some problems and limits in advanced industrial economies. The innovation district, suitable for the era of urban innovation, convergence of industry, housing, leisure, and related variety, emphasizes cooperation through the convergence of various innovations, workshops and industries, and communities. It is important to build a quintuple helix based on cooperative governance through public-private partnerships, integrate the physical and cultural atmosphere, and service industries that strengthen the place prestige. Beyond the industrial aspect, innovation districts can facilitate changes in urban amenities and lifestyles and creative atmosphere, such as diversity, lifestyle, charms, and openness, and promote social vitality and economic interactions. The governance of innovative districts can promote inter-organizational exchanges, and combinations. When knowledge is created through exchanges between companies, it also affects changes in the governance system, evolving from a rigid and centralized system to an open, dynamic, and organic system. Through the innovation policy, the existing Central Business Districts (CBD) can be able to be transformed into a Central Lifestyle Districts (CLD).
