ABSTRACT
As a novel interdisciplinary subject of information science and ethics, informational ethics first originated in the 1970s in western world, and has a short history of over 30 years. Besides computing ethics and network ethics, its research components still include all the ICT-induced ethical issues, such as ethical issues caused by tele-information, satellite technology, network technology, and ethical issues induced by mass media, news, libraries, and files, etc. As an example of the prosperity of informational ethics, library ethics emerged and develops rapidly recently. As a component of social libraries and scientific libraries, hospital libraries face a series of new issues, including hospital library ethics and the professional ethics of hospital librarians. This paper explores the ethical self-discipline of hospital librarians.
ABSTRACT
The changes of parathyroid hormone (PTH),calcitonin(CT)of three different anesthesia methods were observed perioperatively in 38 patients who were divided into two age groups (22 ~ 50 and 51 ~ 60). Postoperative serum Ca, P levels decreased as compared with preoperative values,espe.cially in the old. age groups with no statistic significance. These results indicate that during anesthesia and operative stress the CDS is inhibited and the regulation of the autonomic nervous system is affected, with obscure the relationship between parathyroid hormone, calcitonin and Ca, P with the alteration of Ca,P metabolism. Serum Ca may increase to the baseline by supplement of calcium gluconate during and after operation, but the operation after 4 ~ 5 days, serum Ca may also return to normal without any intervention.
