Design and Implementation of a College Graduate Employment Information Management System

随着高校的扩大招生，每年毕业人数也在不断增加，使得管理学生就业信息的工作内容变得繁重和枯燥。就业信息管理包括学生基本数据的录入和审核，毕业生就业信息录入和按系别、专业、行业、区域等方面统计毕业生的就业人数以及就业率，如果继续沿用手工方式进行处理，工作效率低下，即使经过多次校对，错误仍无法避免。因此，毕业生的就业信息管理信息化成为学校学工处就业指导中心急需解决的问题。 本系统是以河池学院就业信息管理的实际情况为基础的，依据上报教育厅数据的要求进行设计和开发。本文研究了就业信息管理系统当前开发现状，提出了适合广西高校就业管理工作特点的解决方案。通过了解高校（以河池学院为例）的就业数据管理实际情况...With the college enrollment expansion, the number of graduates each year is also increasing, so it causes that the management of the graduate job information becomes very hard and boring.

Growth Engine with a Sound Private SMEs Sector and Knowledge-based Economy: Lesson from Singapore

新加坡在过去二十多年不断鼓励民间投资和支持以科技创新为基础的创业活动产生了两个效果:一是加强了民间中小企业尤其是科技创新型中小企业创业经济成分,逐步改变了其经济对政府关联企业和大公司的过份依赖;二是科技创新使产业结构出现了从传统制造业经济为主向知识经济为主的转变。这一经济结构和产业结构的调整有效地解决了其传统经济模式中的增长“瓶颈”问题,为抵御外部经济冲击和保持长期稳定增长奠定了坚实基础。本文从经济增长动力角度分析新加坡经济发展过程中存在的动力缺陷问题,并考察其政府采取的系列应对措施。From the perspective of Growth Engine of Economy, two 揵ottle-neck?problems have been undermining the soundness of the well-known Singapore economic development model East Asian Economic Model(EAEM), which is characterized as a centralized capitalism. The first problem is the oversize of Government-Linked Companies (GLCs) and the second one is the unbalance of industrial structure with the semiconductor-led manufacturing sector. These problems became major concerns of government, industries and academy as well. Fortunately, the efforts made by government during the past two decades contributed much to the development of technology-based SMEs in private sector and the development of the knowledge-based economy as a whole. These developments help to solve the 揵ottle-neck?problems and fill up the gaps existing in economic development 揺ngine?of traditional EAEM, and consequently enhance its capability to tackle with the cycle vibration of economy and crisis. A well-balanced knowledge-based economic structure is critical to the long-term sustainable development and is the base on which recovery could be conceived without much suffering

Study on the Supersonic Degradation of the Injurant in Domastic

研究了不同空化状态下超声作用下对厦门 竹员 竹当 湖水、污水处理厂污水、啤酒废水及不同浓度的洗涤废水中有害物质的降解作用 ,从而探讨超声作用温度、时间、功率及 PH值变化对废水中有害物质降解的影响 .发现了一些超声作用与有害物质之间的基本关系 :超声作用对生活污水中洗涤剂和氨氮有明显的降解作用 ,并且其作用受 p H影响较大 ,降解程度随超声作用的功率 ,作用时间的增加而增加 ,随温度的提高先增高后降低 ,随起始 p H值降低而增高 .对超声作用降解有害物质的初步摸索结果 ,为进一步研究、开发新的降解途径作了必要的铺垫This experimental study is about the supersonic degradation of the injurant of the Yuandang Lake, the sewage factory and different concentrate sewage, in different cavitating conditions. The effects of the supersonic temperature, time, power and variation of pH on the degradation were investigated. It was experimentally found that there existed relationships between supersonic wave and poisons. The degradation effect of supersonic is obvious on the detergent and NH 4 N coming from the urban waste water. Furthermore, the pH of influent had pronounced effect. The power of the supersonic wave and the affecting time were also be found to have positive effect on the degradation degree. Raising temperature make the degradation degree increase, but decrease when the temperature was too high. A low pH value would be in faver of increasing the degradation degree. The present work would be helpful for development of new degradation ways

Study on the Condition of Oil Pollution and Self-purification at Dapeng'ao, Daya Bay

将已知浓度的污染物石油烃加入到取自大亚湾大鹏澳天然海水中，进行污染物自净能力实验室模拟试验，探讨了各种条件下微生物对有机物降解的影响，用有机物浓度、ATP、DO、BOD5、COD 描述了有机物的降解过程。根据实验结果，得出 BOD5 和 ATP 可用来指示降解过程中微生物量的变化；此外，在一定条件下，石油烃的生物降解一级反应方程可描述为 OIL＝17.442 e－0.1949d 。In this paper, petroleum hydrocarbons are added to the natural seawater sample from Dapeng'ao, Daya Bay. The simulative experiment on self-purification ability of pollutant is carried out in the laboratory, and the influence on the degradation of organic matters by microbe under several different conditions is discussed and described with the concentration of organic matters, ATP, DO, BOD and COD. According to the experimental results, BOD5 and ATP may be used to indicate the change of the number of microbe during the degradation process. Under certain conditions, the equation of first-order reaction of biological degradation of petroleum hydrocarbon can be defined by the express on: OIL=17.442e-0.194 9 d.MBRS基金项目 (S9622) 资
