Results & conclusions : 1. Disharmony between yin and yang, disharmony between organs, disharmony of essence, qi, spirit, blood and body fluid are the main features of aging. 2. ST36, BL18, BL10, CV24, ST1, BL23 have been most frequently used for acupuncture to treat blurred vision caused by aging. For moxibustion, ST36 has been most frequently used. 3. GB2, TE21, TE17, SI19, TE3 are the mainly used points for acupuncture to treat tinnitus and deafness caused by aging. For moxibustion, LI1 and BL15 have been most frequently used. 4. CV3, CV7, CV4, BL67, LR8, LR4 have been most frequently used to treat difficulty in urination caused by aging. 5. LI11, GB34, GB30, LI4, ST36, TE10, TE5, Sama (extra point) have been most frequently used to treat numbness, paralysis and bi syndrome caused by aging.

전세계 국가는 21세기 메가 트렌드인 기술 융합(Technology Convergence) 추세에 발 맞춰 정보통신(IT)분야 미래비전 및 전략수립에 몰두하고 있다. 그리고, 자국의 국부 증대 및 신산업 창출을 위해 WWRF (Wireless World Research Forum), AmI (Ambient Intelligence), and mITF (mobile IT Forum)등의 공학적 시나리오를 기반으로 한 연구를 하고 있다. 하지만 국내의 경우 비전연구 및 전략수립에 대한 연구가 초보단계로 미래전략 수립에 능동적으로 대처하기에는 미흡하다는 지적이다. 따라서, 본 논문에서는 시나리오 기법을 활용한 선진국의 공학적인 미래전략연구 사례를 분석하고, 공학적인 시나리오 비전연구 방법을 제시한다.

Automatic Vision Inspection (AVI) systems automatically detect defect features and measure their sizes via camera vision. It has been populated because of the accuracy and consistency in terms of QC (Quality Control) of inspection processes. Also, it is important to predict the performance of an AVI to meet customer's specification in advance. AVI are usually suffered from false negative and positives. It can be overcome by providing extra information such as 3D depth information. Stereo vision processing has been popular for depth extraction of the 3D images from 2D images. However, stereo vision methods usually take long time to process. In this paper, retro optical system using reflectors is proposed and experimented to overcome the problem. The optical system extracts the depth without special SW processes. The vision sensor and optical components such as illumination and depth detecting module are integrated as a unit. The depth information can be extracted on real-time basis and utilized and can improve the performance of an AVI system.

본 연구에서는 두 가지 읽기 방법으로 저시력인과 정상시력인의 문장 맥락효과를 비교하였다. 실험 1에서는 자기조절읽기(self-paced reading) 방법을, 실험 2에서는 신속순차제시(rapid serial visual presentation) 방법을 사용하여 문장과 무선단어열에서 정상시력 참가자와 저시력 참가자의 읽기속도를 비교하였다. 두 실험 결과에서 저시력 참가자의 읽기속도는 정상시력 참가자에 비해 현저히 감소하였으나, 맥락효과는 읽기 방법에 따라 상반된 양상을 보였다. 자기조절읽기를 사용한 실험 1에서는 정상시력보다 저시력에서 맥락효과가 컸고, 신속순차제시를 사용한 실험 2에서는 저시력보다 정상시력에서 맥락효과가 컸다. 본 결과는 맥락 정보가 처리될 시간이 충분히 허용되는 읽기 상황에서는 정상시력에 비해 저시력 읽기에서 맥락의 역할이 증가하나, 시간적 제약이 주어지는 읽기 상황에서는 반대로 정상시력에 비해 저시력 읽기에서 맥락의 역할이 감소함을 시사한다.

The visual sensing of human hands plays an important part in many man-machine interaction/interface systems. Most existing visionbased hand detection techniques depend on the color cues of human skin. The RGB color image from a vision sensor is often transformed to another color space as a preprocessing of hand detection because the color space transformation is assumed to increase the detection accuracy. However, the actual effect of color space transformation has not been well investigated in literature. This paper discusses a comparative evaluation of the pixel classification performance of hand skin detection in four widely used color spaces; RGB, YIQ, HSV, and normalized rgb. The experimental results indicate that using the normalized red-green color values is the most reliable under different backgrounds, lighting conditions, individuals, and hand postures. The nonlinear classification of pixel colors by the use of a multilayer neural network is also proposed to improve the detection accuracy.

This paper addresses photometric distortion problems of a compact 3D scanning sensor which is composed of a micro-size and inexpensive camera-projector system. Recently, many micro-size cameras and projectors are available. However, erroneous 3D scanning results may arise due to the poor and nonlinear photometric properties of the sensors. This paper solves two inherent photometric distortions of the sensors. First, the response functions of both the camera and projector are derived from the least squares solutions of passive and active calibration, respectively. Second, vignetting correction of the vision camera is done by using a conventional method, however the projector vignetting is corrected by using the planar homography between the image planes of the projector and camera, respectively. Experimental results show that the proposed technique enhances the linear properties of the phase patterns that are generated by the sensor.

The spread of cloud computing, digital computing, and the popular social media platforms have led to increased growth of data. That growth of data results in what is known as big data (BD), which seen as one of the most strategic resources. The analysis of these BD has allowed generating value from massive raw data that helps in making effective decisions and providing quality of service. With Vision 2030, Saudi Arabia seeks to invest in BD technologies, but many challenges and barriers have led to delays in adopting BD. This research paper aims to search in the state of Big Data Analytics (BDA) in Saudi higher education sector, identify the barriers by reviewing the literature, and then to apply the design-reality gap model to assess these barriers that prevent effective use of big data and highlights priority areas for action to accelerate the application of BD to comply with Vision 2030.
