  • Understanding of chemical composition and energy contents in tree is important to develope strategies of renewable energy policy to cope with climate change. Residual biomass as renewable energy source was evaluated and focused on the bark-containing branches. Chemical analysis studies were conducted for different part of yellow poplar (Liriodendron tulipifera), which were partitioned to inner bark, outer bark, small branches, medium branches, big branches and trunk. The variations in hydrophobic extractives, hydrophilic extractives, lignin, carbohydrate compositions, energy contents (higher heating value) and the ash content were determined. The inner and outer bark had higher ash content, hydrophobic and hydrophilic extractives content, and higher energy content than those of tree trunk. Polysaccharides content in inner and outer bark was quite lower than those of stem or branches. Based on the energy content of residual biomass, replacement of fossil fuel and greenhouse gas emission abatement were calculated.

  • Socialization of doctoral students refers to the process through which they acquire various types of information about their work, department, university, and discipline for their future careers. This study aims to investigate information behaviors, with emphasis on identifying types of information exchanged in mentoring between faculty advisors and their doctoral students in library and information science (LIS). As a first step to developing a content framework for LIS doctoral mentoring, the author interviewed ten LIS doctoral students from nine U.S. universities. Based on data from these interviews, the author identified sixteen types of information exchanged: language, history, coursework, research, skills, teaching, networking, structure, politics, goals, strategies, values, norms/tradition, rules/policies, benefits, and personal life. In comparison with a content framework used, four dimensions were newly added. In addition to the identification of content dimensions, the author observed four meaningful contextual levels to which the content types can be applied: work, department/school, university, and discipline. The qualitative data also showed that interpersonal factors of advisees/advisors and contextual factors might relate to information exchange in doctoral mentoring. In a following paper, the author will present the results of a follow-up survey that tests and generalizes the findings of this study.

  • 数字内容在给公司带来机遇和挑战的同时也极大的改变了我们的生活. 创意企业整合视频, 图片, 文本和数据进行数字化过的音频, 开发新产品或服务, 创作数字经验推广自己的品牌. 大多数有关数字内容的文献是关于基本概念或者营销的发展. 其实, 比起普通产品或服务的传统价值链, 数字内容产业似乎有更多的潜在价值. 因为相当多的数字内容是免费的, 价格, 作为信息的质量或价值的指标, 不是必须被感知的(Rowley 2008). 很显然, 当前数字内容的主题是 "价值" 和关于消费者对数字内容的感知价值的研究. 本文讨论了体验价值在消费者评估数字内容时的优势. 本文在对数字内容 "价值" 的理解方面有两个不同但是相关的贡献. 第一, 基于数字内容与普通产品和服务的比较, 本文提出了两个关键特点使得体验战略适合数字内容: 无形和接近于零的再造成本. 最重要的是, 基于对公司的理想化的价值和客户的感知价值之间的差异的讨论, 本文强调了数字内容的价格和定价与普通产品和服务的不同. 无形的结果是, 价格可能并不反映顾客感知价值. 另外, 数字内容的成本处在发展阶段可能非常高但再造会大幅缩水. 而且, 由于前面提到的价值鸿沟, 这个价格政策改变因不同的数字内容而不同. 例如, 平价战略通常用于电影和音乐(Magiera 2001;Netherby 2002), 而有持续的需求的数字内容如在线游戏和杀毒软件的问题牵涉到一个更复杂的效用和极具竞争力的价格水平. 数字内容企业必须探索各种各样的策略来克服这个缺口. 对于广告, 形象, 口碑等常用的市场战略和他们对顾客感知价值的影响的研究变得至关重要. 中国数字内容产业正变得越来越国际化, 并引起了具有各自竞争优势的国家和地区的关注. 2008-2009中国数字内容产业年度发展报告(CCIDConsulting 2009)表明, 在国内需求和政府政策的大力支持下, 中国数字内容产业在2008年保持了大约30%的快速增长, 表明了这个产业在明显的初期扩张阶段. 在中国, 需要更新的杀毒软件和其他软件程序使用季度定价政策. 用户可以免费下载试用版, 用6个月或一年. 如果他们更久的使用, 连续的付款方式是必要的. 他们在试用阶段检测数字内容的优良度, 决定是否要付继续使用. 对于中国的音乐和电影工业的发展战略, 体验最初没有被广泛的应用, 虽然其他国家的公司注意到体验的重要性并探索了相关的战略(如客户在下载前有好几秒可以免费听听音乐). 由于上述原因, 杀毒软件在中国可以代表数字内容产业而且在中国杀毒市场探索了体验价值在顾客的数字内容感知价值中的优势. 为了提高调查数据的可靠性, 该研究集中在那些有使用杀毒软件经验的人群. 实证结果显示, 体验价值对顾客对数字内容的感知价值有积极的影响. 换句话说, 因为数字内容是无形的, 再造成本几乎为零, 客户的评估是根据他们的体验. 另外, 形象和口碑不产生积极的影响, 只对体验价值有影响. 这就是说, 数字内容价值链不同于普通产品或服务. 体验价值有显著的优势并调节形象和口碑对感知价值的作用. 这个研究结果有助于了解为什麽在发展中国家存在免费的数字内容下载. 客户只有通过体验它才可以感知数字内容的价值. 这也是为什么政府如此扶持发展数字内容. 其他发展中国家在起步阶段的数字内容企业可以借鉴这里的建议. 另外, 基于体验战略的优势, 公司应该更努力投资于客户的体验. 由于数字内容的特点和价值鸿沟的存在, 顾客只有经历了他们真正想要的才能感知更多的无形的数字内容的价值. 而且, 因为再造成本近乎为零, 公司可以使用体验战略, 以提高客户对数字内容的理解.

  • High Xe-content PDP characteristics are discussed. A high efficacy, up to 5 lm/W for a 50% Xe in Ne gas mixture, is realized in 4-inch color PDP test panel designs with low cost stripe-type barrier rib structures, that are powder blasted in soda lime glass. Furthermore, for a high Xe-content a high luminance can be obtained with a relatively small electrode area. Therefore the inter cell gap and the driving margin can be increased in a stripe-type barrier rib structure. Finally, for a high Xe-content the panel lifetime increases, due to increasing luminance and firing voltage stability. Clearly, these findings may direct the design development for next generation PDPs towards a high Xe-content

  • The purpose of this study is to investigate awareness of librarian's job prospects, and to do this a survey was conducted with 502 college students in 14 Departments of Library and Information Science around Korea and 753 librarians in libraries and related agencies. The study results are as follows. First, satisfaction with educational curriculum was higher in students than librarians. Second, both students and librarians regarded workplace based practical training as employment requirements and also evaluated certifications and academic performance as important requirements. Third, both groups asked that information on employment rates be available in a timely manner, and perceived that the librarian's job prospects were not bright. Therefore, in order to improve employment of librarians, it will be necessary to establish a job information system, reorganize the current educational curriculum into a practice-oriented curriculum, and introduce the national curriculum statements (NCS)-based curriculum.
