대학교수 직무발명에서 논문발표나 대회출품으로 인한 개시 제한 문제점 연구

Korea has the patent law regulating the terms of the novelty of inventions like other countries. If all elements of disclosed objects are the same as(or similar to) those of applied claims, the secrecy of the application of the above applied claims is considered to be cracked, the result of which is the failure of patent acquisition. However if the his(or her) self disclosure time is no later than 1 year before the his(or her) self filing time, his(or her) self application could be accepted to be valid on the premise that any other people should not interfere with the application before the filing time. This situation is very dangerous in terms of secrecy keeping. Anybody is willing to(or is ready to) interfere with the application no later than 1 year before his(or her) self filing time. In other words, the destiny of the applicant is at stake of anybody`s arbitrary decisions. Therefore professors should not disclose employee inventions(service inventions) in the public such as thesis papers or conference materials before the notification of their employers` OK decisions within four months of the date of employees` reports. Furthermore until the arrival of their employers` OK decisions should professors not file their applications. If professors` filing actions before their employers` OK decisions would be detected, professors could become criminals. Accordingly, for example, professors can not apply for students` invention contests together with their fellow students. Co-works by a professor and his(or her) fellow students could become the clues of the intents of employee inventions(service inventions) disclosures, which are crimes in Korea.

Objective: We aimed to identify the effects of proprioceptive neuromuscular facilitation (PNF) stretching on pain, hip range ofmotion, and functional disability in patients with chronic low back pain. Design: Randomized controlled trialMethods: In total, 45 patients with chronic low back pain were randomly divided into a conventional stretching group (n=22) and a PNF stretching group (n=23). Both interventions were performed three times per week for 6 weeks. Assessments were madeusing the visual analog scale, Flexion-Abduction-External Rotation test, modified Thomas test, prone hip extension test, andOswestry disability index before and after the 6-week intervention period. We conducted a paired t-test to compare thewithin-group findings before and after the intervention. An independent t-test was used to compare the between-group differences. The statistical significance level was set at α=0.05, for all variables. Results: Both groups showed significant improvements in pain, hip range of motion, and functional disability after theintervention (p<0.05). A significant difference was observed in pain, hip range of motion, and functional disability in patientsbelonging to the PNF stretching group (p<0.05). Conclusions: This study provides evidence that the application of PNF stretching can effectively reduce pain and improve hiprange of motion and functional disability in patients with chronic low back pain.

The night vision that notifies obstacles in front of the car to support driver`s vision at night driving has been developed. The conventional infrared ray night vision system is weak to noise and has low contrast. To overcome the problem of infrared ray night vision system, the researching of the night vision using digital camera image is in processing. In this paper, we propose an image enhancement algorithm for the night vision. The proposed algorithm consists of three methods, YCbCr color space conversion , noise reduction and saturation and contrast improvement.

NFC는 135.56MHz 주파수 대역의 비접촉 근거리 무선통신 기술로서 다양한 모드에서의 자료교환, 스마트포스터, 결제 등 다양한 서비스를 지원한다. 특히 NFC 기술의 결제 환경은 이전의 RFID 환경이 가지는 보안 위협이 그대로 존재한다. 따라서 본 논문에서는 NFC 결제 환경에 대한 보안 기법으로 두 가지 방식의 RF통신을 함께 이용하고 보안성을 강화한 프로토콜을 제안한다.
선형 MSR을 이용한 역광 영상의 명암비 향상 알고리즘

In this paper, we propose a new algorithm to improve the contrast ratio, to preserve information of bright regions and to maintain the color of backlight image that appears with a great relative contrast. Backlight images of the natural environment have characteristics for difference of local brightness; the overall image contrast improvement is not easy. To improve the contrast of the backlight images, MSR (Multi-Scale Retinex) algorithm using the existing multi-scale Gaussian filter is applied. However, existing multi-scale Gaussian filter involves color distortion and information loss of bright regions due to excessive contrast enhancement and noise because of the brightness improvement of dark regions. Moreover, it also increases computational complexity due to the use of multi-scale Gaussian filter. In order to solve these problems, a linear MSR is performed that reduces the amount of computation from the HSV color space preventing the color distortion and information loss due to excessive contrast enhancement. It can also remove the noise of the dark regions which is occurred due to the improved contrast through edge preserving filter. Through experimental evaluation of the average color difference comparison of CIELAB color space and the visual assessment, we have confirmed excellent performance of the proposed algorithm compared to conventional MSR algorithm.
좌회전 감응제어를 통한 중앙버스전용차로 운영 효율 개선

서울시 주요 간선도로에 중앙버스전용차로가 2004년 설치 및 운영된 이후 2007년 4월 현재 9개축으로 확대 운영되고 있다. 중앙버스전용차로 구간 중 실시간신호제어시스템이 적용되고 있던 구간에서는 검지체계 손실/버스 전용신호 미설치, 신호운영알고리즘 미개선 등으로 인해 신호운영은 정주기방식으로 제한되어 운영되고 있다. 중앙버스전용차로가 점진적으로 늘어나 대중교통 이용자의 면익이 증가되는 반면, 현재 해당분야의 개선이 없어 신호운영 탄력성은 지속적으로 제약되고 있다.
