Abstract:
目的:了解台湾高雄市社区老年人的养老意愿与养老服务需求现状及影响因素,为社区养老服务提供依据。方法:采取便利抽样方法,抽取高雄市某社区100名65岁及以上的老年人,采用一般情况调查表、养老意愿、生活品质和护理需求调查表对其进行问卷调查。结果:社区老年人居家养老意愿强烈,对居家养老有需求者占66.3%,对社区养老有需求者占23.6%;养老需求多元化,主要体现在生活照料、医疗健康、精神慰藉等方面。结论:居家养老是台湾高雄地区老年人的主要养老意愿,多元化的养老护理需求是台湾高雄地区老年人的主要特点。
Objective: To understand the current situation of the elderly and community care needs of the el-derly in Kaohsiung City, Taiwan, and to provide a basis for community care services. Methods: A convenient sampling method was used to select 100 elderly people aged 65 and over from a com-munity in Kaohsiung City. The questionnaires were surveyed using the general questionnaire, pension willingness, quality of life and nursing needs questionnaire. Results: The elderly in the community had a strong willingness to support the elderly at home. 66.3% of the households had a need for home care and 23.6% of the community pensions. The diversified needs of the elderly were mainly reflected in life care, medical health and spiritual comfort. Conclusion: Home care is the main old-age pension for the elderly in Kaohsiung, Taiwan. The diversified pension care needs are the main characteristics of the elderly in Kaohsiung, Taiwan.
分布式光伏扶贫的模式比较与政策建议

 [PDF]


Sustainable Development (SD) , 2016, DOI: 10.12677/SD.2016.63020
Abstract:
本文就国家现有的光伏扶贫模式进行了比较分析,详细阐述了各方主体所关心的问题。为了使扶贫更加精准,项目更加具有可持续性和利益共生性,笔者提出了一种新的扶贫模式,即“1 + 2 + 4”,以基金为一个中心,全面、详细阐述了基金的“来龙去脉”;以增加农民受益,扩大电力需求为两个基本原则;就近发电、就近并网、就近转换、就近使用为四个基本点。最终,确保政府的扶贫目标得以实现,农民的收入得到保证,企业的投资得以有效地收回,银行的担保得以相对地降低风险,整个农网线路的改造得以完成,弃光现象得以缓解,让扶贫之路的前景充满了一片光明。
The present models of poverty alleviation in China have been compared and analyzed in the article. Also, the questions that all parties concern have been elaborated. To take targeted measures in poverty alleviation, to make the program sustainable and multi-beneficiary, I come up with a new model based on the present patterns project the “1 + 2 + 4”. “1”means that the central point of poverty alleviation project is establishing a fund, whose ins and outs are illustrated thoroughly and carefully. “2” means that the two principles are to raise peasant’s income and to expand electricity demand. “4” means that the four basic points are to generate electric power nearby, to interconnect electricity nearby, to convert electricity nearby, to use electricity nearby. When all the things talked above can be taken account seriously, the governmental goal of poverty alleviation, the long-lasting income of famers, the paid-off investment of enterprise, the lower risk of bank’s guarantee and the rural electric network alteration are only matters of time.

年龄与风险决策中框架效应间关系及其机制探析
Age-Related Influence for Framing Effect in the Risky Decision-Making Tasks
 [PDF]


Advances in Psychology (AP) , 2013, DOI: 10.12677/AP.2013.35037
Abstract: 风险决策中的框架效应是决策研究的重要部分,不同年龄段的框架效应可能有显著差异。目前年龄与风险决策中框架效应关系的实证研究主要有三类观点:一是年龄与框架效应无关,二是框架效应随年龄增长而增大,三是随年龄增长,个体决策表现出从双向框架效应向单向框架效应的转变。本文从神经基础、认知加工风格以及信息加工双通路说及其对前景理论的修正等三个视角解读了年龄与框架效应之间的复杂关系,并认为,随年龄增长,个体加工情绪情感类(尤其是积极情绪情感类)信息能力的增强可能是导致框架效应随年龄变化的重要原因。
Studies of framing effect in risky decision-making played an important role in rational deci- sion-making. There might be significant age-related changes of framing effects. Previous studies mainly had three findings: first of all, participants with different ages showed little differences in framing effect; Next, framing effect became larger with the increasing age; Finally, participants’ decision shifted from bidirectional to unidirectional framing effect with age increased. We reviewed the complicated relationships between framing effect and age, under the construct of neural correlates, cognitive processing style, dual information processes and the modified prospect theory; Moreover, we supposed that the increasing advantage of proc- essing emotional information, especially positive emotion might be the key reason of age-related changes in framing effect.

复合材料学报 , 2013,
Abstract: 为了研究铁电相BiFeO3对复合薄膜磁性能的影响,在LaNiO3(LNO)缓冲层的Si(100)衬底上旋涂制备了含有0、6、9、10层等不同厚度BiFeO3的层状CoFe2O4-BiFeO3(CFO-BFO)多铁复合薄膜。采用XRD、SEM以及TEM对其结构和形貌进行了表征,采用振动样品磁强计测量磁性,研究了不同厚度BFO对复合薄膜磁性的影响。结果表明:CFO和BFO在异质结构薄膜中共存。缓冲层LNO和铁磁相CFO薄膜具有精细微观结构及明显界面。铁电相BFO的厚度对CFO-BFO复合薄膜的磁性能产生了很大影响。在含有不同层数铁电相BFO的复合薄膜中,含有9层BFO复合薄膜的饱和磁化强度最大,达到了230emu·cm-3,相比无铁电相BFO的薄膜,饱和磁化强度提高了18.6%。初步讨论认为:随着铁电相BFO厚度的增加,CFO与BFO之间的应力传导引起了复合薄膜饱和磁化强度的提高。

Abstract: 将W粉和Se粉按一定比例混合,直接密封在石英管中加热或高能球磨、压片,在Ar气氛中加热,得到了不同形貌的WSe2纳米结构.利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM、HRTEM)分析了WSe2纳米结构的组成、微观形貌和组织形态;利用UMT-2摩擦试验机考察了WSe2作为HVI500液体基础油添加剂的摩擦磨损性能.研究结果表明:直接密封加热得到的产物为棒状WSe2纳米材料,最小棒直径为6nm;球磨、压片后加热得到WSe2纳米颗粒,颗粒的平均尺寸在50nm以下,二者都具有层状结构和良好的结晶性.添加质量分数5%的WSe2纳米材料作为基础油添加剂能够显著降低摩擦系数,减少磨损,增强了材料抗疲劳磨损能力.

Abstract: 目的研究盐酸关附甲素在大鼠尿中的代谢产物。方法大鼠iv盐酸关附甲素后收集尿,用高效液相-质谱联用方法测定。通过与标准化合物的色谱保留时间、分子离子峰、碎片离子峰对照从而鉴定i相代谢物。通过用葡糖醛酸酶和硫酸酯酶酶解鉴定其水解产物(苷元)从而确定ii相结合物。结果大鼠尿中发现i相代谢物关附醇胺和关附壬素;尿经过葡糖醛酸酶和硫酸酯酶酶解后,产生关附甲素和关附壬素。结论盐酸关附甲素在大鼠体内可以转化为关附壬素、关附醇胺、关附甲素葡糖醛酸和硫酸结合物、关附壬素葡糖醛酸和硫酸结合物。经过生物转化,代谢产物的极性增加,药效下降。
