As the vehicle performance continues to evolve, research is being conducted to utilize image information for more accurate vehicle positioning. In a multi-object vehicle, it is possible to perform more accurate positioning by combining the different image information captured by each vehicle. In this paper, we introduce a technology that integrates image information captured by each aircraft using ROS. OpenCV's Image Matching Algorithm (Stitcher) is used to implement a system that combines image information from cameras attached to each vehicle.

The study to deliver data faster and more safely from 5G Mobile Communication has been made. The current TCP communication has structural problems, so it‘s not suitable for ultra-speed, ultra-low latency, and hyper-connectivity. IETF has standardized QUIC to deliver faster and more safely, but further study on security is needed. It has verified the possibility of attacks by writing and experimenting attack scenario for the three items out of 11 security considerations presented by IETF QUIC Draft - Handshake Denial of Service Attack, Amplification Attack, Version Downgrade Attack.

It is very important to understand and interpret the meaning of the sigma level correctly through the Six Sigma project. Especially, the confusion over the relation between sigma level from the short-term point of view and defective proportion or DPMO from the long-term point of view may make a big gap between expected results of the Six Sigma project and real results in the field. The one-tail approximation is commonly used to calculate the sigma level both in most literatures introducing Six Sigma and actual cases of the Six Sigma project. Since the one-tail approximation undervalues the sigma level of the fields such as business and service of which the sigma level is generally low, however, there can be misleading results of the explanation of the sigma level and inappropriate project evaluation. This paper describes the relation between sigma level and defective proportion in detail and clears the difference between the one-tail and two-tail approximation.

Until the mid 1900’s, Costume Jewel교 was lead by Gabriel Coco Chanel or the same fashion designers like her in France. Chanel made a new vogue by a fashion attaching importance to the women’s movement, and she filled up the simplicity of her garments. Dior made a huge success by showing the feminine beauty which was concealed under the military look of women who worked instead of men during the war. His design was more sensual and showy than those of Chanel. Schiaparelli, who presented a remarkable and endless changing ornaments under surrealism when the core was moving to the United States because of the World war, Gustavo Trifari of Napoli, who succeed by processing materials and technology development, Coppola e Toppo from Milan who was famous for a spectacular biz necklace, Hatte Carnegie, Fernand Steinberger from Austria, who made colorful animal shaped custom jewels Lea stein, made of synthetic resins, Stanly Hangler from U.S. who is famous for his ornaments made by colorful glasses braided densely lead the time. At that time America could have prosperous days because of the cheap manpower from different countries, the technology of ornament industry and a capital for it from the Jews who avoided the Nazi. However, in the later 20th century, as the industries of U.S grew, the economic structure changed from manufacturing industry to service industry and financial business, and the U.S began to produce by outsourcing, and during the 1980’s and 1990’s, Korea was an important outsourcing country. However, these days, the China, which is led by cheap labor, is a representative jewel producer. Our Costume Jewelry enterprises have enough technology and knowledge accumulated by an old OEM export system, and Korea is throwing up the largest amount of ornament majored University graduated students in the world every day because of enthusiastic education, having the largest labor. Therefore, now we also should make our own high classed brand in the custom Jewel industry.

Acute rhinosinusitis is a rare cause of abducens nerve palsy. Most reported cases with VIth cranial nerve palsy associated sphenoid sinusitis are fungal sphenoid sinusitis, mucocele, or severe bacterial sinusitis. In this report, we present a patient with acute mild sphenoid sinusitis presented as abducens nerve palsy associated with prominent sphenoid pneumatization to the Dorello’s canal.

Isolated brainstem invlovement of neurocysticercosis is rare. We present the clinical and radiological features of a patient with a solitary cysticercus granuloma in the brainstem confirmed by MRI and CSF ELISA test. Good response was obtained from conservative treatment, using praziquantel. We believe that patients from regions where cysticercosis is endemic, who have no systemic disease, who present with nonprogressive symptoms and signs of brainstem involvement, and display a solitary ring-enhancing mass in the brainstem measuring less than 20mm on neuroimaging may be managed conservatively.

Post-shunting subdural hemorrhages are usually small and self-limited, and they can be recognized on the routine post-operative CT examinations. However, delayed subdural bleeding may occur without any clinical symptoms or signs. Thus the hematoma remains undetected, and it can be increased in size and sometimes become calcified with time. We experienced a case of 15-year-old male with a large calcified subdural hematoma who had undergone shunt operation 10 years previously. With pertinent review of the literatures, we discuss the possible mechanism of calcification and the proper way of treatment in calcified chronic subdural hematoma.
