최근 인공지능(AI)과 자율주행 기술의 발전으로 이동형 방범 로봇이 자율 순찰과 실시간 위험 탐지를 수행하며 기존 감시 체계의 한계를 보완하고 있다. 그러나 기존 시스템은 영상 전달과 단순 객체 인식에 의존하여 위협 상황을 정밀하게 판단하는 데 한계가 있다. 이러한 문제를 보완하기 위해 본 논문에서는 자세 추정과 객체·얼굴 인식 정보를 융합하여 무기 소지 여부를 판별하고 결과를 3차원 디지털 트윈 환경에서 시각화할 수 있는 상황인식 기반 위험인물 판별 및 디지털 트윈 연동형 방범 로봇 시스템을 제안한다. 실험 결과, 무기 탐지 정확도는 mAP50 기준 95.55%, 위험인물 판별 정확도는 1~2m 거리 구간에서 82.5%를 기록하였으며, Jetson Orin NX 기반 on-device AI 환경에서 준실시간 위협 인식이 가능함을 확인하였다. Recent advances in Artificial Intelligence (AI) and autonomous driving technologies have enabled mobile security robots to perform autonomous patrols and real-time threat detection, complementing the limitations of existing surveillance systems. However, existing systems rely on video transmission and simple object recognition, limiting their ability to accurately assess threat situations. To address these issues, this paper proposes a context-aware dangerous-person discrimination and digital twin security robot system that integrates pose estimation with object and facial recognition information to discriminate weapon possession and visualize the results within a 3D digital twin environment. Experimental results showed a weapon detection accuracy of 95.55% (mAP50) and a dangerous person discrimination accuracy of 82.5% within a 1–2 meter range, demonstrating near real-time threat recognition on a Jetson Orin NX–based on-device AI platform.

Tudor朝 Somerset公 主導下의 宗敎改革論

李東燮 漢城大學校 1986 論文集 Vol.10 No.1

The lst Duke of Somerset (1506-1552), protector of England, held virtually royal power for two years (1547-9) during the minority of Edward Ⅵ. Born Edward Seymour, he became the lst Earl of Hertford in 1537 and the lst Duke of Somerset in 1547. The son of a Wiltshire nobleman, he was the brother of Jane Seymour, Henry Ⅷ's third wife. A favoured courtier, he held a series of royal appointments and rose in the peerage. He also commanded a force in Scotland and was the most prominent man in the kingdom at the time of Henry's death in 1547. Having secured the protectorship and been created duke under the reign of Edward Ⅵ, Somerset sought to implement his own policies, notably union with Scotland and radical Protestant reforms. His religious policies including those of religious uniformity and royal supremacy and his anti-Catholic view on the Eucharist were the aspects of his protestant ideas. But his exercise of the royal supremacy of the King Edward Ⅵ to secularize church property antagonized the Catholics. Discontent over these policies, combined with agrarian unrest, led to the rise of his enemies. The Earl of Warwick had him arrested and false charge of treason in 1549. Somerset was executed on January 22, 1552. But his protestant ideas and radical reforms influenced the future development of English Reformation.

Korea Highway Corporation has been introducing hi pass system that already is running to clear a habitual traffic jam and improve a service in advanced nation. This work investigates passage time of hi pass system usage and non usage vehicles on cheonggye, pankyo, and seongnam tollgate according to traffic, vehicles sort and delay time and quantitatively compute emission of air pollutants (CO, NOx, VOCs, TSP) and fuel consumption amount using COPERTⅢ model according to vehicles sorts. Reduction rate of emission on hi pass system usage vehicles appeared more about 50% than on general tollgate usage vehicles. If whole vehicles use the hi pass system, Reduction rate of emission about CO, NOx, VOCs, TSP, total air pollutants and fuel consumption amount showed 53%, 20%, 68%, 39%, 48% and 45% respectively.

Chemical Imprints of the Upwelled Waters off the Coast of the Southern East Sea of Korea

이동섭,김일남 한국해양과학기술원 2003 Ocean science journal Vol.38 No.3

We made intensive observations on the coastal upwelling off the coast of the southern East Sea from June to August in 2001. The upwelling exhibited a weekly waxing and waning. The coastal upwelling of the year 2001 was characterized by abrupt outbreaks and the small local scale. Upwelling occurred more frequently off the coast of Ulsan and Gampo as reported by the earlier observers. The spread of freshly upwelled colder water was varied by each upwelling event. Generally cold waters were carried away northeastward off Pohang province. The upwelled cold waters were saltier than the resident surface waters. The pH and salinity-normalized alkalinity support the idea that the upwelled waters originate from the interior of the East Sea. The extraordinarily high concentration of dissolved oxygen suggests that the upwelled waters are closely connected to the southward flowing North Korea Cold Current. Although a lower primary productivity was reported for the upwelling region, underway surface fluorescence measurement revealed that the recently upwelled waters supported up to an order of magnitude higher algal biomass than the ambient waters. Because thermohaline circulation of the East Sea is so vigorous, with an estimated time scale of less than one hundred years, that the coastal upwelling should be considered not as an anomaly but as a regular component of a circulatory system. A quantitative understanding of upwelling seems to be a key to elucidate material cycling and the associated biological production in the East Sea.

This study was Designed to examine the applicability of low density ceramic filters to actual processes through long term experiment to reveal the characteristics ceramic filter, durability against thermal and mechanical shocks. The experiment was also conducted at 600℃ and 300℃. 1m long low density ceramic filter with 60㎜ outer diameter and 10㎜ thickness was tested with dust collected from cokes process of P-steel. Collection efficiency ranged 99.98∼99.99% and conditioning was completed after 150∼200hrs. Resistance coefficients of filters range 5.9×10^10 at 600℃, 1.2×10^10 at 300℃. Long term experiments show that conditioning was completed after 155 hours of test at 300℃ and 165 hours at 600℃ with high collections efficiencies. Also tested filters show mechanical stabilities at different particulate feed rates ranging 0.5g/min to 1.0g/min. Results show that tested filters can be applied to commercial processes with one year guarantee.

Mobility of structural foundations for shipboard equipments has a crucial design factor for developing advanced marine vessels, such as cruise ships, naval ships, and offshore structure, in terms of vibration and noise control. In this study, a mobility of a structural foundation for a shipboard diesel generator has been quantitatively assessed with the methods based on a finite element method and an empirical formula. For this purpose, the assessment procedures with finite element analysis and empirical formula have been summarized. Mobilities of structural foundations for a shipboard diesel generator have been numerically estimated by the methods. The results have been compared with those of impact tests for real ship structures.

Purpose: Real-time monitoring of urinary bladder volume can not only provide information on urinary bladder function more precisely in laboratories and in the setting of intravesical pressure monitoring, but can also help areflexic neurogenic bladder patients have notice of the timing for optimal urination to prevent secondary complications. Thus we introduce a new implantable bladder volume monitoring device and its usefulness. Materials and Methods: Ten male Sprague-Dawley rats were used under intraperitoneal anesthesia. Two microelectrodes produced by a micro-electrical-mechanical systems (MEMS) process were stitched onto each side wall of the urinary bladder and 25 G needles were inserted through the bladder dome. The distances between two microelectrodes converted from capacitances recorded by LCR meter were monitored in real-time during cystometry. Urinary bladder volume was estimated with its shape approximated as a sphere. Results: Estimated bladder volume correlated well statistically with infused volume in (p<0.05 regression analysis). Since the urinary bladder was filled with over 0.6 cc normal saline in each rat, estimated urinary volume was not different than infused saline volume (p>0.05, repeated measures ANOVA). Conclusions: In our animal model, an implantable volume-monitoring device produced reliable data. Therefore, we expect that it should be an excellent tool for detecting urinary bladder volume and producing more accurate and useful information during urodynamic laboratory studies with small animals. Furthermore, we expect that this study will be the foundation of research for the clinical application of bladder volume monitoring devices to areflexic neurogenic bladder patients.
