The purpose of this paper is to provide the classification of Jordanian Colloquial Arabic variations and its phonological features by way of surveying the linguistic situation in Jordan. Since Ferguson(1959) first proposed the English term "diglossia" modeling it on the French diglossie, there have been several attempts to describe the diglossic situation within the Arab world. But the concept of diglossia which refers to the coexistence of the High variety (MSA) and the Low variety (regional dialects) in a society has recently changed to the triglossic situation in which three Arabic varieties(including the Middle varieties) or more than it exist. In this respect, Jordan society also does not go beyond the triglossic situation. Likewise, Jordan society has the High variety (MSA) , the Middle varieties, and the Low varieties. Chapter 2 is simply a survey of the linguistic situation in Jordan in terms of the triglossic situation, and classifies Jordanian Arabic into three varieties - Madani, Fallahi, and Bedouin according to the regional and phonological distinctions. Chapter 3 provides a linguistic analysis of each of three varieties, focusing on the phonological distinctions such as preservation of the interdentals, voiced realization of the /q/ as /g/ , and preservation of the gender distinction in the second and third person plural of pronouns and verbs. In order to attain the goal the paper is designed to investigate Jordanian Colloquial Arabic spoken by educated groups and most particularly by the university students.

The objective of this study was to compare the shear bond strengths of five adhesive systems to the enamel and dentin of primary and permanent teeth. Fifty noncarious primary and fifty permanent teeth were collected and stored in an 0.1% thymol solution at room temperature after extraction. The tested adhesives were: Adper Scotchbond Multi-purpose Plus Adhesive (SM) Adper Single bond 2 (SB), Clearfil SE Bond (SE), Adper Prompt L-Pop (PL), G-Bond (GB). For the shear bonding test, the labial and lingual surfaces of primary and permanent teeth were used. To obtain a flat surface, the labial and lingual surfaces of the teeth were sanded on SiO₂with number 600 grit and then divided into 20 groups of 10 surfaces each. All samples were theromocycled in water 5℃ and 55℃ for 1000 cycles. The results were as follows: 1. For primary enamel, shear bond strengths of SM and SB were significantly higher than that of SE and also SM, SB, and PL were higher than GB(p<0.05). 2. For primary dentin, there were no significant differences among the shear bond strengths of any other bonding systems except differnece between SE and GB. 3. For permanent enamel, SB showed significantly higher mean shear bond strength than those of any other bonding systems(p<0.05). 4. For permanent dentin, SM showed significantly higher mean shear bond strength than that of PL and GB(p<0.05). 5. Between the primary enamel and dentin, there were significant differences in SM, SB, and GB, whereas there was statistically significant difference in PL between the permanent enamel and dentin(p<0.05). 6. Between the primary and permanent teeth on enamel, there were no significant differences among all bonding systems, whereas there were statistically significant differences in SM and SB between the primary and permanent teeth on dentin(p<0.05). 본 연구에서는 최근에 개발된 치과용 접착제를 대상으로 유치와 영구치의 법랑질과 상아질에 대한 결합력을 비교 평가하여 입상에서 상아질 접착제를 적절하게 선택하는데 도움을 주고자 시행하였다. 실험재료로 Adper Scotchbond Multi-purpose Plus Adhesive (SM; 3M ESPE,USA),Adper Single bond 2 (SB; 3M ESPE,USA),Clearfil SE Bond (SE; Kuraray Medical Inc.,Japan),Adper Prompt L-Pop (PL; 3M ESPE,USA),G-Bond (GB:GC Cooperation Toyko,Japan)를 이용하여 전단결합강도를 평가하여 다음과 같은 결과를 얻었다. 1. 유치 법랑질에서 전단결합강도는 SM이 28.47±7.93 MPa로 가장 높았고 SB (28.18±6.84),PL (24.02± 6.14),SE (21.70±6.56),GB (17.70±6.68) 순이었다. SM과 SB는 SE보다 통계적으로 유의하게 높은 결합 강도를 보였으며,SM,SB,PL은 GB보다 높았다(p<0.05). 2. 유치 상아질에서 전단결합강도는 SE가 28.72±14.44MPa로 가장 높았고,PL (20.10±6.13),SM 07.72± 10.65),SB (15.48±2.66),GB (10.10±5.45) 순이었으며 SE와 GB간 에는 유의한 차이가 있었으나,다른 군 들 간에는 유의한 차이가 없었다. 3. 영구치 법랑질에서의 전단결합강도는 SB가 28.36±5.68 MPa로 가장 높았고 SM (22.77±4.63), PL(22.05 士6.57),SE (21.74±4.62),GB (15.60±6.75)순이었다. SB는 다른 접착제보다 통계적으로 유의하게 높은 결합력을 나타냈으며,GB는 가장 낮은 결합력을 보였다(p(0.05). 4. 영구치 상아질에서의 전단결합강도는 SM이 28.22±5.56 MPa로 가장 높았고,SB (21.68±7.44),SE (20.13 ±9.88),GB (14.30±6.81),PL (14.18±5.88)순이었으며,SM은 PL,GB와 유의한 차이가 있었다(p<0.05). 5. 유치의 법랑질과 상아질 간에는 SM,SB,GB에서 유의한 차이가 있었고,영구치 법랑질과 상아질 간에는 PL에서 유의한 차이가 있었다(p<0.05). 6. 유치 법랑질과 영구치 법랑질 간에는 모든 접착제에서 유의한 차이가 없었으나,유치 상아질과 영구치 상아질 간에는 SM과 SB에서 유의한 차이가 있었다(p<0.05).

최진영,최홍석,이광무,공성곤,김인수 제어·로봇·시스템학회 2010 International Journal of Control, Automation, and Vol.8 No.5
Detection, tracking, and understanding of moving objects of interest in dynamic scenes have been active research areas in computer vision over the past decades. Intelligent visual surveillance (IVS) refers to an automated visual monitoring process that involves analysis and interpretation of object behaviors, as well as object detection and tracking, to understand the visual events of the scene. Main tasks of IVS include scene interpretation and wide area surveillance control. Scene interpretation aims at detecting and tracking moving objects in an image sequence and understanding their behaviors. In wide area surveillance control task, multiple cameras or agents are controlled in a cooperative manner to monitor tagged objects in motion. This paper reviews recent advances and future research directions of these tasks. This article consists of two parts: The first part surveys image enhancement, moving object detection and tracking, and motion behavior understanding. The second part reviews wide-area surveillance techniques based on the fusion of multiple visual sensors, camera calibration and co-operative camera systems.
