The Chinese Culture University is a private Taiwanese university located in Yangmingshan in Shilin District, Taipei, Taiwan. CCU was established in 1962 and is one of the largest universities in Taiwan with an enrollment of about 32,000 students. Satellite campuses are located in the Jianguo, Ximending, and Zhongxiao East Road areas of Taipei City.Originally founded as Far East University in 1962 by Chang Chi-yun, the school was renamed College of Chinese Culture by President Chiang Kai-shek in 1963 and finally became Chinese Culture University in 1980. CCU is now organized into twelve academic colleges: Liberal Arts, Foreign Language and Literature, Social science, Science, Engineering, Business Administration, Journalism and Communications, Arts, Environmental Design, Law, Agriculture and Education.

Two sets of lateral vibration equations for a spinning axially loaded twisted Timoshenko beam have been studied. The compressed axial load is assumed to be normal to the shear force and tangential to the axis of the beam for the two systems, respectively. A quadratic eigenvalue problem of a real gyroscopic system is formulated and utilized to investigate the free vibration and buckling stability of various twisted Timoshenko beams. Some typical results are compared with numerical results in the published literature to validate the accuracy of the presented analysis. The influence of thickness-to-width ratio, twist angle, spinning speed and axial load on the natural frequency and buckling load of Timoshenko beams has been investigated and discussed. Comparisons between the results of the two sets of system equations are also made to justify the effect of the axial load for various Timoshenko beams. © 2010 Elsevier B.V. All rights reserved.

Green roofs have multiple environmental benefits and are widely used around the world. In keeping with this mainstream movement, the use of green roofs has been increasing in Taiwan in recent years. This paper reviews policies promoting green roof development in Taiwan, and compares the environmental and economic performance of green roofs in Taiwan to those in East Asian countries and worldwide. National and regional government policies have stimulated the development of green roofs by establishing goals for reducing carbon emissions of cities, promoting green construction, mitigating heat island effects, and increasing urban flood control. Local studies of green roof performance are few, other than thermal investigations. These studies have shown that green roofs significantly contribute to thermal reduction and moderate temperature variations around buildings. One study sampled stormwater runoff from green roof sites and found that sediment and nutrient concentration on these roofs are up to ten times higher than on conventional bare roofs; however, acid rain can be neutralized by green roofs. Hydrographs have shown that reductions in runoff from green roofs are not as great as expected because retention and detention are affected by high rainfall intensity, which is the typical precipitation pattern in Taiwanese cities. Without additional maintenance, green roofs can contribute to nonpoint source pollution in urban cities in wet and hot weather zones, because of high runoff and associated mass loading. Moreover, the environmental benefits of green roofs in Taiwan may not be as significant as those in other countries in which utility costs are higher, where decreasing energy consumption and CO2 emissions would be of greater benefit. © 2012 Elsevier B.V.

Currently, lots of enterprises widely use social network site for marketing campaigns, however, there are still limited literature in the related fields. This study investigated the determinant factors for the successful implementation of Facebook marketing by enterprises. Using the marketing communication model developed by Hoffman & Novak [20] as well as source credibility, social ties, consumer value and the involvement theory, this study tested the impact transferring messages through media on the message receiver's decision-making behavior. A total of 256 smart phone Facebookers were selected as research samples, and the hypotheses was tested using regression analysis. The research findings suggested that advertising messages provided by close friends only affect consumer brand attitudes, but advertising messages provided by commercial sources affect both consumer brand attitudes and purchasing intentions. Utilitarian and recreational advertising messages affect consumer advertising attitude, brand attitudes, purchasing intentions and involvement. Lastly, consumer involvement partially mediates the effects of utilitarian advertising and recreational advertising on advertising attitude, brand attitudes and purchasing intentions. Source

Most existing adaptive neural controllers ensure semiglobally uniform ultimately bounded stability on the condition that the neural approximation remains valid for all time. However, such a condition is difficult to verify beforehand. As a result, deterioration of tracking performance or even instability may occur in real applications. A common recourse is to activate an extra robust controller outside the neural active region to pull back the transient. Such an approach, however, has been restricted to dynamic systems with matched uncertainty. We extend it to strict-feedback systems with mismatched uncertainties via multiswitching-based backstepping methodology. Each virtual and actual controller of the proposed design switches between an adaptive neural controller and a robust controller, with the switching algorithm being sufficiently smooth and, hence, able to be incorporated with the backstepping tool. The overall controller ensures globally uniform ultimate boundedness while simultaneously avoiding the possible control singularity. Simulation results demonstrate the validity of the proposed designs. © 2012 IEEE. Source

Peng, H-T. Changes in biomechanical properties during drop jumps of incremental height. J Strength Cond Res 25(9): 2510-2518, 2011-The purpose of this study was to investigate changing biomechanical properties with increasing drop jump height. Sixteen physically active college students participated in this study and performed drop jumps from heights of 20, 30, 40, 50, and 60 cm (DJ20-DJ60). Kinematic and kinetic data were collected using 11 Eagle cameras and 2 force platforms. Data pertaining to the dominant leg for each of 3 trials for each drop height were recorded and analyzed. Statistical comparisons of vertical ground reaction force (vGRF), impulse, moment, power, work, and stiffness were made between different drop jump heights. The peak vGRF of the dominant leg exceeded 3 times the body weight during DJ50 and DJ60; these values were significantly greater than those for DJ20, DJ30, and DJ40 (all p < 0.004). The height jumped during DJ60 was significantly less than that during DJ20 and DJ30 (both p = 0.010). Both the landing impulse and total impulse during the contact phase were significantly different between each drop height (all p < 0.036) and significantly increased with drop height. There were no significant differences in the takeoff impulse. Peak and mean power absorption and negative work at the knee and ankle joints during DJ40, DJ50, and DJ60 were significantly greater than those during DJ20 and DJ30 (all p < 0.049). Leg, knee, and ankle stiffness during DJ60 were significantly less than during DJ20, DJ30, and DJ40 (all p < 0.037). The results demonstrated that drop jumps from heights >40 cm offered no advantages in terms of mechanical efficiency (SSC power output) and stiffness. Drop jumps from heights in excess of 60 cm are not recommended because of the lack of biomechanical efficiency and the potentially increased risk of injury. © 2011 National Strength and Conditioning Association.
