The purpose of this study is to design and develop a digital game-based courseware on cubic net called Happy Cuber, and to explore the learning effect by using it on the spatial recognition abilities of fifth graders.

本研究的目的就是设计与发展正方体展开图的数位教材(取名为Happy Cuber)，并且透过本教材来探讨国小五年级学童使用教材后的学习成效。

This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

本系统主要包含前端脉波撷取及后端软体分析两部分，其中前端脉波撷取部份是以非侵入式的红外线量测方式，双通道同步量测受测者手指与脚趾的光容积变化描记图，同时将此讯号经类比处理电路及中央控制单元输出成为数位容积波，再传送至个人电脑中；而在后端软体分析部份，因数位容积波之特徵点皆出现於波形中急剧变化的部份，故本论文以瞬间斜率变化量来定位脉波讯号中的起搏点及主波峰顶点，并利用小波转换演算法（wavelet transformation algorithm）来分析重搏切迹与重搏波顶点；程式撰写主要以Matlab为核心，结合Visual Basic的图形化使用者操作介面，增加系统与使用者间的亲和力。

The main purpose of this research was to explore whether the 「creative digital story-telling course」 can help to improve story quality, creativity, and writing attitude, and understand the feasibilities and limitations of teaching similar courses to higher-grade students in primary schools. The researcher adopted 「nonequivalent pretest-posttest designs」 as a quasi-experimental study.

本研究的主要目的是探讨「创意数位说故事课程」对故事创作的品质、创造力、和作文态度是否有帮助，并了解此类课程应用於国小高年级作文教学的可行性及局限性。

Results In static phantom studies, the percent error of mean activity obtained by Carson's method was reduced to about 9 %, and it is less than that of image-derived method using maximum likelihood expectation maximization (about 14 %). In simulated dynamic phantom studies, the vessel component could be extracted using ICA in image and sinogram domain. In sinogram domain, the six components extracted by ICA could be obtained quickly.

在静态物理假体实验结果来看，使用Carson's method计算出感兴趣区域活性的百分比误差( 9%)比直接从影像取得活性的百分比误差( 14%)来得小；从数位模拟动态假体实验结果来看，独立成份分析法运用在影像空间或是弦波图空间上，都可以将血管分离出来，但从弦波图空间上得到各个独立成份相对於影像空间就快得多；imageICA和sinogramICA计算出的输入函数的标准化均方根误差分别是0.57和0.28。

Above all, this thesis realizes that the most important influence of digitalization to photography is "after" it. That is, most of the changes is happening in the phase of post-production but the process of photoing.

於是，本文了解到数位化对於摄影的影响应是「后於」摄影，也就是大部分都在影像处理的阶段产生了重大的变革，而在摄影的流程中则相对影响较小。

Due to the simplicities of the current signal processing and events detection methods, the CPU is idled for substantial amount of time. Thus, in the future, more advanced techniques such as adaptive filtering and wavelet analysis can be implemented for event detection to increase the accuracy and reliability.

本系统目前并未利用数位讯号处理单晶片的全部能力，往后若能将自适性滤波器及小波等更先进的讯号处理方式实现於系统中，将能更进一步增强讯号侦测的能力，同时提高本系统的可靠性。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
