基于DOI 系统的中日韩三国之间科技信息共享

为促进亚洲各国之间的科技信息资源共享和科研合作,在这些区域内,通过一站式服务获取相关信息至 关重要。3 年前,基于谅解备忘录（MOU）,中国科学技术信息研究所（ISTIC）、日本科学技术振兴机构（JST）及韩国 科学技术信息研究院（KISTI）建立了基于现有DOI 系统的长期合作机制。首先概要介绍分别由三机构运行管理的各自 国家的DOI 系统,以及三国之间的国际合作进展。然后,通过引入云服务平台的概念,提出未来的合作框架,以进一 步促进资源共享。     

Factors Affecting International Students’ Decisions on Destination for Studying Abroad: A Case Study in China

This qualitative study explores how to better attract international students as perceived from the viewpoints of both international students and university administrators. The 7Ps marketing mix conceptual framework and thematic analysis were utilized to analyze qualitative data solicited from both focus group discussions involving 75 international students and in-depth interviews with four administrators at two public universities in Yunnan province, China. The results indicate that two factors mainly affect students’ decisions on an international education destination: geographical location (Place) and cost of study (Price). Furthermore, the study recommends applying the 7Ps as a totality in university recruitment practices.     

Habitual rowing exercise is associated with high physical fitness without affecting arterial stiffness in older men

The present study elucidated the effects of habitual rowing exercise on arterial stiffness and plasma levels of the vasoconstrictor endothelin-1 and the vasodilator nitric oxide (NO) in older men. Eleven rowers (68.0 ± 1.6 years) and 11 sedentary control older men (64.9 ± 1.1 years) were studied. Peak oxygen uptake (36.0 ± 1.7 vs. 27.7 ±1.9 ml · kg(-1) · min(-1)), leg press power (1346 ± 99 vs. 1077 ± 68 W), and HDL-cholesterol (75 ± 5 vs. 58 ±3 mg · ml(-1)) were higher and triglyceride (78 ± 9 vs. 120 ± 14 mg · ml(-1)) was lower in rowers than in control participants (all P < 0.05). Arterial stiffness indices (carotid β-stiffness and cardio-ankle vascular index) and plasma endothelin-1 and NOx (nitrite + nitrate) levels did not differ between the two groups. These results suggest that habitual rowing exercise in older men is associated with high muscle power and aerobic capacity, and favourable blood lipid profile without affecting arterial stiffness or plasma levels of endotheline-1 and NO.     

老年体质的异质性及生命历程中累积的影响

人的体质异质性是客观存在的,它是生物学因素以及社会学因素作用的结果。生命历程中的许多事件对体质产生正或负的效应,这些效应不断累积叠加,加大了体质的异质性分化。老年期则是众多事件累积性效应的集大成阶段,同时也是成年之后体质异质性分化程度最高的时期。在人生历程中重大生活事件以及个人的能动性对体质的影响最为重要,因此加强与体质有关事件的干预以及调动人的主观能动性是提高体质水平、保证进入老年期后有一个较高体质平台的有效措施。
