University students' behavioral intention to use mobile learning: Evaluating the technology acceptance model

As many Korean universities have recommended the implementation of mobile learning (m‐learning) for various reasons, the number of such tertiary learning opportunities has steadily grown. However, little research has investigated the factors affecting university students' adoption and use of m‐learning. A sample of 288 Konkuk university students participated in the research. The process by which students adopt m‐learning was explained using structural equation modeling technique and the Linear Structural Relationship (LISREL) program. The general structural model based on the technology acceptance model included m‐learning self‐efficacy, relevance for students' major (MR), system accessibility, subjective norm (SN), perceived usefulness, perceived ease of use, attitude (AT), and behavioral intention to use m‐learning. The study results confirmed the acceptability of the model to explain students' acceptance of m‐learning. M‐learning AT was the most important construct in explaining the causal process in the model, followed by students' MR and SN.

Responses of endothelial cells to extremely slow flows

The process of blood vessel formation is accompanied by very minimal flow in the beginning, followed by increased flow rates once the vessel develops sufficiently. Many studies have been performed for endothelial cells at shear stress levels of 0.1-60 dyn∕cm(2); however, little is known about the effect of extremely slow flows (shear stress levels of 10(-4)-10(-2) dyn∕cm(2)) that endothelial cells may experience during early blood vessel formation where flow-sensing by indirect mass transport sensing rather than through mechanoreceptor sensing mechanisms would become more important. Here, we show that extremely low flows enhance proliferation, adherens junction protein localization, and nitric oxide secretion of endothelial cells, but do not induce actin filament reorganization. The responses of endothelial cells in different flow microenvironments need more attention because increasing evidence shows that endothelial cell behaviors at the extremely slow flow regimes cannot be linearly extrapolated from observations at faster flow rates. The devices and methods described here provide a useful platform for such studies.

An Examination of the Host Country Factors Affecting the Export of U.S. Video Media Goods

The United States is by far the leading exporter of video media goods in the world. It is also the biggest investor in theatrical films, spending over $63 million per theatrical production and leading the world in box-office receipts. This article investigates the host country factors that have influenced the export of U.S.-based video media products, including film and television programs. It was found that economic environment, geographical proximity, technological infrastructure, and market size influenced the purchase of motion pictures and video programming from the United States. In addition, countries with better economic environments, implementation of intellectual property rights, political rights, larger market size and cultural differences, and language similarity seemed to import more heavily broadcasting content products from the United States.

农业文化遗产资源旅游开发的时空适宜性评价——以贵州从江"稻田养鱼"为例

科学认定和评价资源是旅游开发利用的前提,其中资源旅游开发的时段选取和空间选定问题尤为重要.本研究以贵州从江"稻田养鱼"农业文化遗产资源为例,立足"遗产资源-旅游开发"两方面、"时间-空间"双维度构建指标体系,时遗产资源旅游开发的时空适宜性进行了定量评价.结果表明:①夏初(6月)和秋季(9月～10月)是从江县遗产资源旅游开发的最佳季节(月份);②东北部的"斗里-西山-雍里-丙蛛-高增-贯洞-洛香-庆云"是目前进行旅游开发的最佳区域;受旅辩可进入性差的影响,西南部各乡镇遗产资源的旅游开发适宜度较低;③提高下江镇遗产资源的景观优势度和完整度可贯通东北一西北部适宜区构筑旅游大区,提升全县的旅游吸引力.     

“草叶”:美国文化的产物——《草叶集》中“草叶”之意蕴研究

(半)正/负定矩阵数学符号表示的科学性分析

科学的数学符号表示方法对于科学研究工作具有很重要的意义。目前部分教材和文献中(半)正定和(半)负定矩阵的数学符号表示不够科学,易引起读者的误解,并由此导致错误的推论。因此,对这种表示方法的不科学性的指出与更正是非常必要的。本文对这种不科学的表示方法进行了深入的分析,并提出了两种较为科学的(半)正/负定矩阵的符号表示法,以弥补原来的符号表示法所存在的缺陷。这将有助于读者和编者正确地理解及恰当地应用(半)正和(半)负定矩阵于各类教学、科研与工程实践之中。
