关键词： AIS   航标标识   符号   助航   标准  

摘要： 自20世纪90年代开始将AIS作为一项新技术引入航运业以来,这种有别于雷达的、可获取实时海上交通信息的新型助航系统已经被证明在航海领域具有良好的应用前景,在航标上设置AIS便是其中之一。尽管国际社会做出大量努力,有关AIS航标标识符号一直没有一个国际标准,AIS航标在AIS、MKD、ECDIS、雷达和VTS上显示符号各不相同,严重影响了AIS航标的使用。AIS航标标识符的统一制定对我国影响面较大。我国应积极加强AIS航标符号的研究,以保护我国的利益,并提升我国在海事技术领域的话语权。

摘要： 数字对象惟一标识符（digitalobject identifier，DOI）是对包括互联网信息在内的数字信息进行标识的一种工具。在传统的出版物中，书刊、磁带、光盘都有国际标准编号（ISBN、ISSN、ISGN）及其条形码，作为出版物的惟一标识。这些标识使出版物得到有效的管理，便于读者查找和利用。而网上的文档一旦变更了网址便无从追索。数字信息标注DOI如同出版物的条形码，是一个永久和惟一的标识号。

关键词： Liquid solutions   Mars   GIMS technology   Spectroellipsometers  

摘要： A human mission to Mars requires the solution of many problems that mainly linked to the safety of life, the reliable operational control of drinking water as well as health care. The availability of liquid fuels is also an important issue since the existing tools cannot fully provide the required liquid fuels quantities for the mission return journey. This paper presents the development of new methods and technology for reliable, operational, and with high availability chemical analysis of liquid solutions of various types. This technology is based on the employment of optical sensors (such as the multi-channel spectrophotometers or spectroellipsometers and microwave radiometers) and the development of a database of spectral images for typical liquid solutions that could be the objects of life on Mars. This database exploits the adaptive recognition of optical images of liquids using specific algorithms that are based on spectral analysis, cluster analysis and methods for solving the inverse optical metrology tasks.

关键词： administrative data   fuzzy matching   linkage   Medicare   program evaluation  

摘要： In community-based wellness programs, Social Security Numbers (SSNs) are rarely collected to encourage participation and protect participant privacy. One measure of program effectiveness includes changes in health care utilization. For the 65 and over population, health care utilization is captured in Medicare administrative claims data. Therefore, methods as described in this article for linking participant information to administrative data are useful for program evaluations where unique identifiers such as SSN are not available. Following fuzzy matching methodologies, participant information from the National Study of the Chronic Disease Self-Management Program was linked to Medicare administrative data. Linking variables included participant name, date of birth, gender, address, and ZIP code. Seventy-eight percent of participants were linked to their Medicare claims data. Linking program participant information to Medicare administrative data where unique identifiers are not available provides researchers with the ability to leverage claims data to better understand program effects.

关键词： Small-scale fisheries   Fisheries -- Research   Fishery technology   Fishing techniques  

摘要： Fishing gear losses remain a serious problem for marine life;these losses are also the source of an invisible fishing mortality. This study is an analysis of this problem within the artisanal fisheries of Istanbul. From September 2009 through May 2010, face-to-face interviews were conducted in 27 fishing ports for a total of 282 questionnaires. Estimates of lost fishing gear were 229.48 km of set nets, 2700 m of longlines, and 14 fish traps. Turbot nets had the highest loss ratio (54.73%), followed by bonito nets (16%), red mullet nets (7.36%), and encircling trammel nets (4.83%). The four major causes of net loss were: conflicts with other gear types (trawl and purse seine), conflicts with cargo vessels, bottom structure hindrances, and bad weather conditions. Bottom structures were the single factor in net losses for longlines and fish traps. The study observed that large quantities of nets had been lost, and that each net type showed a positive relationship between the number of nets used and the number of nets lost. Separate zones for artisanal and industrial fisheries are recommended as a realistic approach to reduce the losses of fishing gear and the impact of 'ghost fishing'.
