公司社会责任背景下的公司对消费者的社会责任问题

我们拟通过《公司法》总则性的规定，根据《消费者权益保护法》与《产品质量法》等现有的立法规范与司法实践，制定相关的配套法规与实施细则来更好地保障消费者权益。在社会公众权利意识不断加强的条件下，从立法上完善消费者的监督权，提升社会公众的监督意识，通过激励的方式来促使公司内部自身社会责任意识的强化与制度化，从而促进公司将社会责任融入企业的经营与发展过程之中，更好地保障消费者权益，构建诚信与和谐的市场环境，促进社会经济的发展。     

我国高等院校本科生导师的定位与基本职责——以笔者本科生导师实践为例

本科生导师制起源于英国牛津大学,2002年起我国高等院校开始引进本科生导师制。本科生导师应从德才兼备的专业课教师中遴选。导师应为本科生教育教师系统中极为重要的不可替代、不可或缺的组成部分,他们应当成为本科生做人、做学问的引路人。导师应当与辅导员等各种类型的教师团结协作,各司其职,共担人才培养大任。导师的基本职责有二:一是导师应当注重"育人",通过与本科生的思想交流,培养具有健全和高尚人格的人才;二是导师应当充分发挥其独特的专业优势,"传道、授业、解惑",培养出优秀的专业人才。     

Simultaneous analysis of d-3-methoxy-17-methylmorphinan and l-3-methoxy-17-methylmorphinan by high pressure liquid chromatography equipped with PDA

d-3-Methoxy-17-methylmorphinan (Dextromethorphan, DXM), which is a structural analog of morphine and codeine, has been widely used as a non-narcotic antitussive agent. It is a safe drug in therapeutic dose and does not produce analgesic effects, while its enantiomer, l-3-methoxy-17-methylmorphinan called levomethorphan (LXM) is a potent narcotic analgesic. DXM has been widely abused in Korea due to its hallucinogenic effect in large doses; therefore, the health authorities have regulated its use as a psychotropic agent since 2003. As its abuse has been serious, a possibility that DXM would be smuggled into Korea has also increased. Moreover, it has been suspected that there was the possibility of the adulteration or substitution of DXM with LXM due to their chemical similarities. Therefore, it was necessary for us to establish the enantiomeric separation of DXM and LXM. In this study, a liquid chromatographic method using a chiral column capable of separating stereoisomers of DXM as well as analyzing the major metabolites of DXM, 3-methoxymorphinan, 3-hydroxymorphinan, and 17-hydroxymethylmorphinan was developed. The validation of a method was studied through repeatability of retention times. Using this method, 32 confiscated DXM samples were analyzed to identify the enantiomers of DXM. As a result, DXM was detected in all samples and there was no evidence of the adulteration or substitution of DXM with LXM. Nevertheless, the stereochemical analysis of DXM and LXM is important not only to identify starting materials for illegal drug manufacture but also to understand the trends of abused drugs.     

大鼠急性心肌缺血动物实验模型的改进

目的改进大鼠急性心肌缺血动物实验模型时,提高手术的成功率和动物成活率。方法比较传统方法与改进方法动物试验的成功率。结果传统方法成功率只有60%,改进方法成功率达到90%以上。结论改进后的方法能大大降低手术难度,减少实验费用,优于传统方法。     

血液和脑脊液中利多卡因的气相色谱-质谱检测研究

目的建立血液和脑脊液中利多卡因的气相色谱-质谱联用定性、定量检测方法。方法血液或脑脊液盐酸酸化后,氢氧化钠碱化(pH=9),乙醚提取,氮气流下挥干,乙醇定容,气相色谱-质谱联用仪分析,选择离子监测模式检测(86,58,72,87),定性、定量检测血液和脑脊液中利多卡因。结果血液和脑脊液中利多卡因的线性范围为1.0～60.0μg·mL-1(r=0.9999),检出限为0.02μg·mL-1(S/N=3),加样回收率为85%～103%,麻醉致死犬血液和脑脊液中检出利多卡因,结果满意。结论该法选择性好,干扰少,灵敏,准确,可用于生物体液中利多卡因的定性和定量检测。     

公安院校“两课”教学中运用CAI现代教育技术手段的思考

在当前公安院校的“两课”教学改革中,运用现代教育技术手段对教学形式进行大胆创新,是深化“两课”教育教学改革的一个重要途径。对此,公安院校“两课”教师应充分认识运用多媒体辅助教学的优越性;在CAI课件的设计与制作中,找准多媒体技术辅助教学手段与公安院校“两课”教学目标的结合点;在CAI教学主体——教学工具——教学客体的有机互动中,增强公安院校“两课”教学的生动性和实效性。     

信息的定义及哲学本质

21世纪是信息科学蓬勃发展的时期,但人们对信息及其本质还存在不同认识,现有的信息定义均有不足之处。信息的哲学本质可以从四个层面进行分析:信息是客观实在的,信息是一切物质都具有的显示物质存在方式和状态的客观属性,信息是物质间接存在性的标志,信息是物质自身显示自身的属性。     

绵绵不绝"乡愁"路——读《归乡》
