韩国经济发展中教育的作用

教育与经济 2005年第1期21卷 47-49页

作者：贾金英韩国精神文化研究院

近几年中国对一衣带水的邻邦韩国越来越关注,特别是文化领域中“韩流”现象越演越热,经济领域中则纷纷去韩国学习先进的技术及管理经验。国土面积狭小,资源贫乏的韩国为什么比我们这个拥有九千六百万平方公里的资源丰富的大国更先进更... 详细信息

近几年中国对一衣带水的邻邦韩国越来越关注,特别是文化领域中“韩流”现象越演越热,经济领域中则纷纷去韩国学习先进的技术及管理经验。国土面积狭小,资源贫乏的韩国为什么比我们这个拥有九千六百万平方公里的资源丰富的大国更先进更发达呢?有关韩国经济发展原因的研究很多,但大多数是从经济及政治的角度来研究的,本文从教育的角度出发,先对韩国人的教育意识进行考察,然后按照韩国产业化阶段即以轻工业为中心的劳动集约型产业化阶段、着重培养重化工业的资本集约型的产业化阶段以及以电子产业为中心的技术集约型的产业化阶段的顺序对韩国教育在经济发展中的作用进行了论述。

Optoelectronics Letters 2025年第1期21卷 1-6页

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.

The Triple Ionosphere Photo Meter （TRIPM） is a far ultraviolet nadir-view photometer that is onboard the secondgeneration,polar-orbiting Chinese meteorological satellite Feng-Yun 3E （FY-3E）,which was launched on July 5,*** has three channels,and each is used to measure different types of emissions:（1） 135.6 nm airglow produced by the recombination of the O+ions and electrons in the absence of sunlight （nighttime channel）;（2） 135.6 nm airglow from the OI when sunlight is present （daytime/dusk-dawn 135.6 nm channel）;and （3） Airglow in the N2LBH of the TRIPM （daytime/dusk-dawn N2LBH channel）.FY-3E is a satellite operating in the early morning ***,the data are mostly distributed on the dawndusk side or at times when the solar zenith angle is relatively *** this study,combined with simulation calculations,the data are *** further explore the application value of the data products,a model is used to separate the ionospheric radiative recombination contribution from the thermosphere photoelectron impact excitation contribution in the data from the daytime/dusk-dawn 135.6 nm *** approach not only improves the accuracy of O/N2derived from the 135.6 nm channel and N2LBH channel but also provides the ionospheric 135.6 nm radiance at the same time as the *** results show that the 135.6 nm radiance originating from the combination of O+and electrons extracted from the measurement data exhibits similar equatorial anomaly peak structure characteristics and seasonal variations as the corresponding GPS total electron content （TEC） *** the other hand,the separated 135.6 nm radiance generated from the thermosphere photoelectron collision excitation does not contain radiative recombination contributions;thus,the ionosphere influence is greatly avoided when the O/N2is obtained.

为了在使用基于位置的服务时用户的位置信息不被不可信的位置服务提供商所泄漏,k-匿名位置隐私保护已被广泛研究。然而在集中匿名器被黑客控制时原k-匿名算法会泄漏所有用户的位置隐私,在进行k个最近邻目标查询时对网络的负载较重,而Space Twist算法又不能保证k-匿名。提出了一种基于经纬网格的递增KNN位置隐私保护查询算法,将经典的k-匿名算法与Space Twist算法相杂交,并引入经纬网格代替原来精确的位置上报给集中匿名器,从而解决了上述问题。实验证明基于经纬网格的递增KNN查询算法比较节省从集中匿名器到位置服务提供商的服务器之间的网络流量。
