Objective: Training-related injuries and attrition put an additional burden on police and military institutions. Preventing and minimizing musculoskeletal injuries is the primary concern of the Abu Dhabi Police. Therefore, this study aimed to evaluate the correlation between functional movement screen, lower-limb strength, Y-balance test, grip strength and vertical jump and the incidence of musculoskeletal injuries among Abu Dhabi police recruits. Design: Observational analytical study. Methods: An observational study was conducted on 400 male police recruits of Abu Dhabi Police Academy. Physical performance was assessed before the 16-weeks basic police training. Spearman's correlation evaluated the correlation between the performance parameters and the outcome measures and logistic regression predicted the risk factors associated with musculoskeletal injuries. Results: 149 (34.4%) participants reported at least one injury during the basic police training. Comparison between injured and non-injured participants showed significant difference in mean right Y-balance, back-leg-chest dynamometer, and vertical jump (p=0.02, p=0.02, and p=0.04, respectively). Spearman's correlation showed a significant negative correlation between risk of injury and back-leg-chest dynamometer and right Y balance (ρ= -0.11, p=0.03). Logistic regression showed that back-leg-chest dynamometer and right Y balance were significant predictors of injury (p =.036 and p=0.037; Odds ratio=0.96; 95% CI (0.92, 0.99) and Odds ratio=0.99; 95% CI (0.98,0.99). Conclusions: Our findings suggest functional movement screen and grip strength may not independently predict injury rates, balance and lower-limb strength needs to be considered in injury prevention strategies to reduce musculoskeletal injuries.

This research is conducted on temporary street furniture, which is one of the significant factors that comprise the street landscape in modem cities. The primary purpose of this research is to present the guidance on direction of planning by examining the design and installation types of construction and screen fences usually established at construction sites for buildings, roads, parks and etc. The results are as follows: 1. The construction and screen fences at construction sites of urban areas used to be a mere tentative facility to prevent noise and safety accidents but have now incremented their roles to serve not only as a functional but also as an aesthetic element with a city view and harmonization with other elements taken into consideration. In particular, it is noticeable that, based on its unique feature of tentativeness, its role has developed to serve as street furniture that adds variability to the modem city. 2. There are two different types of screen fences: blackout type and transparent type. The transparent screen turns out to be used a lot at the construction site of building a skyscraper or differentiated building in downtown city area or in places where there are buildings of similar types and shapes located along the street in the vicinity of the construction site. 3. The actual cases of adopting the tentative construction and screen fences all at the same time as a single unit have been found in historically and culturally significant architectures with the screen design used to demonstrate the view after completion of construction or the characteristics of the architecture.

Purpose: The aim of this study was to investigate correlations between the Functional Movement Screen (FMS), pain, and performance ability in professional fencing players. Methods: Fifty-six athletes participated in this study. The pain group included those who had a score on a pain-related Visual Analogue Scale (VAS) of ${\geq}$20 and an Oswestry Disability Index (ODI) score ${\geq}$10). In the non-pain group, these scores were: VAS(<20), ODI(<10). The VAS and ODI were used to measure pain throughout the study. Performance ability included motor function of the lower extremities (as assessed by a Modified Functional Index Questionnaire, MFIQ), dynamic balance (Balance system, BS and Posture med, PM), flexor and extensor muscle strength of the lumbar region was recorded as maximal isometric strength. Results: Among athletes who had pain, 5 of 15(33.33%) showed impaired functional movement. Conversely, only 2 of 41(4.88%) of those who had no pain showed such impairment (FMS ${\leq}$14score). The athletes who had pain and who had an FMS score above 14 (10/56; 17.86%) showed a significantly higher score for extensor muscle strength of the lumbar compared with those with pain and an FMS score below 14 (5/56; 8.93%) were significant correlations between the FMS and pain (r=-0.40 to -0.42, p<0.01), the MFIQ (r=-0.33, p<0.05), dynamic balance (r=-0.27 to -0.40, p<0.05-0.01), muscle strength of the lumbar (r=0.27 to 0.29, p<0.05). Stepwise multiple regression analysis showed that the dynamic balance score (${\beta}{\beta}$=-0.41) had slightly more power in predicting FMS score than pain, motor function of lower extremity, or muscle strength. Conclusion: The FMS was significantly associated with values of pain, motor function of the lower extremities, dynamic balance, and muscle strength of the lumbar. However the FMS appears to lack relevance and reasonable evidence to suggest that it is an acceptable measurement tool for functional movement analysis.

Oral screen은 가장 기본적인 기능성 장치로서, 근육의 변화를 도모하여 비정상적인 근육형태와 연관된 초기부정교합의 개선에 적합하다. 이것은 혀와 buccinator mechanism사이의 근평형을 향상시켜, 정상적인 성장이 가능하도록 한다. Oral screen은, (1) 손가락빨기 혀내밀기, 입술깨물기 등의 구강습관, (2) 기도가 열려있을 때의 구호흡, (3) 상악전돌경향을 동반한 경미한 원심교합, (4) 유치열과 혼합치열에서의 개방교합, (5) 무력순 등을 개선하는데 사용된다. Oral screen은 매일 밤, 그리고 가능하다면 낮에도 장착하여야 한다. 장치의 효과는 구순폐쇄훈련을 시행함으로써 발휘된다. 장치를 장착하는 동안, 입술은 장치의 효과를 높이고 구순폐쇄를 향상시키기 위해 항상 접촉한 상태로 유지되어야 한다. 본 증례는 구호흡과 무력순을 보이며 각각 상악절치의 순측경사와 치은비대, 개방교합 양상을 보이는 2명의 어린이환자에게 구순폐쇄훈련을 병행하면서 oral screen을 장착한 결과, 구호흡경향이 줄어들어 치은부종이 감소하였고 구순의 근력과 길이는 증가하여 구순폐쇄가 원활해졌다. 아울러 상악 절치의 경사도가 감소되어 개방교합의 치료에 효과적임을 알 수 있었다.

화소영역에서의 처리방법이 주를 이루고 있는 Multipoint Control Unit(MCU)의 화면분할(Split-Screen) 처리기능은 동영상신호의 실시간 처리에 많은 문제를 갖고 있다. 이를 해결하기 위한 방법이 일부 연구되고 있으나, 이 방법도 실제 적용하기에는 무리가 따르는 복잡한 구조를 갖거나 적용대상이 H.26I으로 한정되어 있다. 본 논문은 ISO/lEC 의 동영상 부호화 표준인 MPEG-1/2를 대상으로 하는 새로운 화면분할 방법을 제안한다. 새롭게 제안한 MPEG화면분할 방법은 완전 압축영역에서 처리를 수행하며 이에 따르는 처리지연이 거의 수반되지 않으므로 실시간 다지점 멀티미디어통신 등에 응용이 가능한 효율적인 방법이다. 또한 이 방법은 MPEG 비트 스트림의 단순 해석 및 조작으로 구현이 가능하며, 압축영역의 분할방법을 사용함으로 화질의 열화를 수반하지 않는다. 제안한 방법에 대한 소프트웨어 시뮬레이션을 통하여 기능의 검증을 완료하였으며, 기존의 방법과 구성의 용이성, 처리에 따르는 지연 그리고 분할처리된 화면의 화질 비교를 통해 제안힌 방법의 효용성을 입증하였다.
