In recent years, e-learning system has been adopted as a training tool in many firms, as it can help employees to complete training in a short time and at a low cost. Within this context, since 2003 the Industrial Development Bureau （IDB） of the Ministry of Economic Affairs （MOEA） in taiwan sponsored more than 50 enterprises each year to help them implement customized e-learning systems. Past research on e-learning mostly focused on one criterion and adopted regression approach, such as examining the relationships between satisfaction or continued usage intentions and various antecedent factors. Although the regression method could uncover the significant factors of e-learning adoption, they can not show the can （weighting） of each factor, and thus firms cannot allocate the optimal levels of resources. To overcome this problem, this study collected factors related to finns implementing customized e-learning systems from a review of the literature and expert opinions, and then constructed a hierarchical factor table. Based on the appropriateness and independence of factors, and as assessed by experts in the project promotion office of the IDB, e-learning solution providers and project leaders of the IDB sponsored enterprises, this paper then designed an Analytical Hierarchy Process （AHP） format questionnaire and sent it to these same experts to gather their responses. The factor weightings were derived based on the Fuzzy Analytic Hierarchy Process （FAHP） method. Finally, analysis of key factors was performed and recommendations provided. Based on the results for this work, service industry firms with limited resources can achieve proper resource allocation and more quickly and successfully adopt customized e-Learning systems.

A Petrographic and Mineralogical Study of Volcanic Rocks from the Mayaxueshan Area, North Qilian Fold Belt, NW China

引用

Acta Geologica Sinica(English Edition) 2002年第1期76卷 15-30页

作者： HSU ta-Wei(徐达伟) SHAU Yen-Hong(萧炎宏) Department of Marine Resources National Sun Yat-Sen University Kaohsiung 80424 China Department of Marine Resources National Sun Yat-Sen University Kaohsiung 80424 China

The Ordovician volcanic rocks in the Mayaxueshan area have been pervasivelyaltered or metamorphosed and contain abundant secondary minerals such as albite, chlorite, epidote,prehnite, pumpellyite, actinolite, titanite, quartz, and/or calcite. They were denoted as spilitesor spilitic rocks in terms of their petrographic features and mineral assemblages. The metamorphicgrades of the volcanic rocks are equivalent to that of the intercalated metaclastic rocks. Thisindicates that both the spilitic volcanic rocks and metaclastic rocks in the Mayaxueshan area haveformed as a result of caledonian regional metamorphism. We suggest that the previously denotedspilitic rocks or altered volcanic rocks should be re-denoted as metabasalts or metabasaltic *** metamorphic grade of the volcanic rocks increases with their age: prehnite-pumpellyite faciesfor the upper part of the Middle Ordovician volcanic rocks, prehnite-pumpellyite to lowergreenschist facies for the lower part of the Middle Ordovician volcanic rocks, and lower greenschistfacies for the Lower Ordovician volcanic rocks. The P-T conditions are estimated as T = 240 - 290deg C and P = 1.5-4.5 kbar for the lower part of the Middle Ordovician rocks, and T = approx 300 degC for the Lower Ordovician rocks. The variations of mineral assemblages occurring at differentdomains of the volcanic rocks were controlled by the variations of the effective bulk composition inthose domains during metamorphism. The geochemical characteristics of Mg-Al chromite in theMayaxueshan volcanic rocks are consistent with an origin of island arc environment.

To control water impairment in urban storm- water, it is important to evaluate changing patterns of water quality parameters in stormwater runoff. Thus, the authors performed a series of experiments to investigate the dynamics of common water parameters during storm events in semi-arid areas, with multiple samples collected and analyzed in field stormwater applications. At this field monitoring site within Mcauliffe Park, Mcallen, Texas, in the United States, a storm event increased the concentra- tions of Escherichia coli （E. coli）, but this event represented a decreasing trend over the entire event period. Besides, peak intensity of different pollutants in the stormwater runoff occurred at different times other than at any peak flows, representing a complexity of the temporal and spatial measurements. Multi-sample per- event approaches recommended based on the complexity of the hydrograph and different peak intensity times of pollutants. In addition, high bacteria and total suspended solids （TSS） concentrations in the initial stage of the storm event should be considered when designing Best Manage- ment Practices （BMPs） and Low Impact Developments （LIDs）. New strategies and solutions for addressing ecohydrological challenges should be proposed to avoid collateral damages to their both common wealth in ecosystems and human well-beings.

Frontiers of Computer Science 2017年第3期11卷 429-443页

作者： Yang-Yen OU ta-Wen KUAN Anand PAUL Jhing-Fa WANG An-Chao TSAI Department of Electronic Engineering Cheng Kung University Talnan 701 China Department of Computer Science and Engineering Kyungpook National Univeristy Daegu 702-701 Korea Department of Digital Multimedia Design Tajen University Pingtung 741 China

This work presents a spoken dialog summariza- tion system with HAPPINESS/SUFFERING factor recognition. The semantic content is compressed and classified by factor categories from spoken dialog. The transcription of au- tomatic speech recognition is then processed through Chinese Knowledge and Information Processing segmentation system. The proposed system also adopts the part-of-speech tags to effectively select and rank the keywords. Finally, the HAPPINESS/SUFFERING factor recognition is done by the proposed point-wise mutual information. Compared with the original method, the performance is improved by applying the significant scores of keywords. The experimental results show that the average precision rate for factor recognition in outside test can reach 73.5% which demonstrates the possi- bility and potential of the proposed system.

在越南的工业化和现代化过程中,能源产业扮演着非常重要的角色。作为拥有丰富的自然资源以及大量的原油储备的国家,越南在这方面的开拓及发展有许多优势。然而,有限的科技水平己为原油开采及加工带来不少困难。虽然近几年来越南已建设了三个炼油厂,但其产量未能满足国内需求。因此,越南石油进出口活动仍值得关注。本文的研宄目的主要是探讨2010-2017年阶段越南燃料贸易、越南与贸易伙伴国的燃料进出口的影响因素。本文所使用的数据来自于世界综合贸易方案(WITS)、国际货币基金组织(IMF)、越南海关(Vietnam Customs)以及CEPII等数据库,反映了越南国内及贸易伙伴国的市场规模、越南与贸易伙伴国之间的距离、过去的殖民关系以及亚洲太平洋经济合作组织(APEC)成员国之间的关系。通过采取引力模型的定量研究方法,本文测量经济规模、市场规模、越南与贸易伙伴国之间的关系、越南作为APEC的正式成员国、过去的殖民关系等各种因素对越南燃料贸易、越南与贸易伙伴国的燃料进出口的影响。研宄结果表明,越南国内经济规模对越南的石油进口量有正面影响,而贸易伙伴国的经济规模对越南石油对外出口量有正面影响。越南国内市场规模对越南石油贸易进口量和贸易总量有着重要影响,而国外市场规模则对越南石油出口量有影响。另外,越南与贸易伙伴国之间的距离对越南燃料贸易、越南燃料进出口有着负面影响。与此同时,成为APEC的成员国与过去的殖民关系也对其有影响。本文在搜集数据之后使用Statal4和Excel进行统计分析。本文的研宄框架和研宄步骤如下:第一章简单概述研究背景及越南目前燃料贸易情况。在东南亚地区,越南是个燃料用量较高的国家。根据越南工商部的报告表明,消费水平在未来几年会有快速提升的趋势,越南将要进口燃料。同时在该地区,越南也有较大的原油出口量,但这几年来,由于国内生产量不能满足国内不断增加的需求,出口金额大幅下降,直接影响到居民生活和设备的运行。因此,越南需要有一个具体的战略,大量投资于生产、分配及出口。从此,需要更加关注燃料出口,避免成为燃料进口国的可能,换言之,需要严格监督越南的燃料贸易活动。近几年来所颁布和修改的相关政策己为企业的发展提供良好条件,越南的进出口活动也随之而快速发展。政府一般会要求相关部门审查并简化各种规定和手续,为企业提供更好的生产和经营环境。另外,对于一些重点发展领域,银行贷款利率也比较低。根据越南海关总局2017年12月12日公布的数据表明,越南进出口金额达4000亿美元,预计2017年全年达4200亿美元。因此,在世界贸易组织(WTO)的排行榜当中,越南的进出口排名有所上升。具体而言,2007年越南的出口金额排在第50位,但到2017年已挤到第27位,同时2007年排在第41位的越南进口金额到2017年已挤到第25位。在该章节也呈现了越南近几年的燃料贸易情况。本研究主要确定越南燃料贸易、越南与贸易伙伴国燃料进出口的影响因素。通过对燃料贸易总量,尤其是燃料进出口现状的分析,本研宄将基于2010-2017年阶段的数据来测算越南和贸易伙伴国的人口、经济发展的区别、距离、作为经济组织的成员国、殖民关系等因素对贸易关系的影响。同时本文也提出推动越南国内能源行业发展的建议。第二章主要梳理关于进出口、两国双方贸易以及引力模型应用的文献。该章节主要涉及到贸易绝对优势理论、比较优势理论、H-0模型(赫克歇尔-俄林)等等。同时也涉及到越南国内外的相关研究。第三章具体阐述研宄方法及数据搜集步骤,同时也提到研宄过程中所遇到的困难及研究的局限。本文采用定量的方法来揭示经济规模、人口数量、距离、作为经济组织成员国、殖民关系等因素对越南燃料贸易、越南与贸易伙伴国燃料进出口的影响。本文使用二手数据进一步统计分析来测算并验证燃料贸易总额、越南与贸易伙伴国燃料进出口总量之间的关系。数据来源于2010-2017年阶段世界综合贸易方案(WITS)、国际货币基金组织(IMF)、越南海关(Vietnam Customs)以及CEPII等数数据库。通过引力模型揭示了越南国内及贸易伙伴国的市场规模、越南与贸易伙伴国之间的距离、过去的殖民关系以及亚洲太平洋经济合作组织(APEC)成员国对燃料贸易及进出口的影响。根据越南的实际情况,引力模型公式如下:lnTotal=α+r In(GDP)+α In(GDP)+α In(POP)+α In(POP)+α In(Distance+αAPEC+αCol)+ε在搜集2010-2017年阶段越南和40个贸易伙伴国的相关数据的过程中,有些国家在所观察阶段初期并没有得到相应数据,因此,本研宄只能呈现316个相应数据(理论上讲,研究对象包括40个国家,时间段为8年,就有320个相应数据)。然而,考虑到这些国家对越南燃料贸易总额所占的比例,他们仍然被放在研究范围之
