According to Hebei Province's actual situation, we choose 6 important variables, which reflect the regional economies level of development. By analysing the data collected, the 11 regions of Hebei Province are divided into fourtypes: the developed, the more developed, the medium and the backward. And there is large differ-ence between the four types of regions. To further promote and realize coordinated development of theHebei Province economy, we should take measures to narrow the gap including making distinctive economic zone and business circle, promoting the regional harmonious development, developing the coastal economic belt and improving the underdeveloped region self-development capabilities.

Programming based on OSGi can bring many advantages, such as modular, standardized, service oriented, dynamisms, and easy reuse, easy extension, easy deployment, and so on. At this issue, we integrate the OSGi and Java Web popular framework which includes Struts, Spring, Hibernate, and build an enterprise applications micro-core architecture called OSSH. Java programmers who are familiar with SSH can experience the benefits of OSGi. Keywords: OSGi; Integration Framework; Java Web; 1. Introduction As the rapid development of hardware and network technology, the software features undoubtedly become more complex, larger, and its requirements change frequently because of the changing business environment. Software companies are facing a global size of the common problems which includes real- time response to new demands, the dynamic deployment of new modules, and rapid assembly of various components of the service [1]. OSGi (Open Service Gateway Initiative) makes all these questions simple. OSGi is an application development framework which is lightweight, loosely coupled, service-oriented [2]. OSGi modules bring a standardized development of organizations and unified way. The OSGi-based systems have many benefits including hot-swappable plug-in architecture, high reusability, efficiency, etc.

PPI Tiongkok sebagai wadah pengembangan minat dan bakat mahasiswa Indonesia memegang peranan penting dalam mempersatukan para pelajar Indonesia di Tiongkok. salah satu misi kami adalah agar para pelajar Indonesia tidak lupa dengan bangsanya sendiri dan suatu saat nanti bisa pulang untuk membangun Indonesia. Oleh karena itu visi Kabinet KB (keluarga berencana) PPI Tiongkok tahun ini adalah memperkuat hubungan internal antar pengurus dan juga meningkatkan kesinergian antara PPIT Cabang. kami yakin dengan hubungan internal yang solid, bahkan hingga mampu menjadi seperti keluarga, ditambah dengan perencanaan yang matang, PPI Tiongkok dapat menghasilkan inisiatif-inisiatif yang dapat berdampak positif bagi mahasiswa-mahasiswa Indonesia yang ada di Tiongkok.

  • Research on English and American Literature and English Teaching
    2020 4th International Conference on Economics, Management Engineering and Education Technology (ICEMEET 2020) Research on English and American Literature and English Teaching Hongyan Zhou Shandong Youth University of Political Science, Jinan, Shandong, 250103, China Keywords: English and American literature, English teaching Abstract: British and American literature is an important part of the entire English teaching process and plays an important role in the entire English teaching. In the process of English teaching, with the introduction of British and American culture as the background and the appreciation of classic literary works as the teaching method, students can enhance their ability to appreciate and analyze works while reading and writing in English. By teaching the knowledge of English and American literature, it is possible to cultivate the comprehensive quality of students and comprehensively improve the quality of English teaching. 1. Introduction The status of British and American literature in English teaching is self-evident, but it has long been neglected in college English teaching. The reason is that there are few college English class hours, limited foreign language level of the students, and relatively weak teachers of college English teachers. However, the author believes that the root cause is still the education concept that emphasizes ability and light quality. Now when it comes to the reform of college English teaching, people think of strengthening the cultivation of students' listening, speaking, reading, writing and other application abilities. Our current college English education is too focused on the training of basic skills. It seems that there is nothing but listening, speaking, reading, writing and translating.

The IVPs with local fractional derivative are considered inthis paper. Analytical solutions for the homogeneous and nonhomogeneous local fractional differential equations are discussed by using the Yang-Laplace transform. 1. Introduction fractional derivative was presented [30].
