This paper briefly reviews the operation principles and features of mechanical sight, optical sight, electrooptical sight and integrated sight. The status of mechanical sight, traditional optical sight, lowlightlevel night vision sight, new electrooptical sight and integrated sight equipped in different nations worldwide is given. The development status and parameters of various typical electrooptical sights as well as simple day and night firecontrol systems are described. It is pointed out that mechanical sight and optical sight are still necessary for future light weapons. However, electrooptical sight shall prevail in equipment procurement, and light weapon sight equipped in the future shall be the integrated electrooptical sight.

Therapeutic horseback riding have been believed as a good media to improve balance ability. We proceeded to do a case study, by the use of a mechanical horse made by Joba EU-6441, Matsushita Electric Industrial Co., Ltd., Japan. This mechanical horse is designed according to the movement pattern of a real horse. The seat is designed to move in a pattern based on the figure of eight. Many clinics begin to adopt the mechanical horses as treatment tools, but its effectiveness in children with ADHD remains unknown.

目前对於ADHD儿童平衡能力的训练及介入成效之研究较少，本研究以骑马治疗进行个案讨论，采用的骑马机(Joba EU-6441， Matsushita Electric Industrial Co。， Ltd。， Japan)是根据真实马运动时的动作模式所设计出来的，临床上认为骑马机有可增进平衡能力的功用，目前已逐渐被临床治疗师广泛使用，但对於骑马机的确切疗效仍没有研究加以证实，尤其是骑马机是否对於平衡能力或是感觉调节能力有所帮助等。
