AbstractBased on the ongoing techniques among control theory, communication networks, and sensor design, unmanned aerial vehicles (UAVs), unmanned undersea vehicles (UUVs) and unmanned surface vehicles (USVs) are experiencing rapid development. Research on these unmanned systems and those intelligent sectors inside has absorbed interests and investments from not only military but also civil organizations. The well-applied fields include surveillance and reconnaissance, surface warfare, antisubmarine warfare, mine countermeasures, oceanic environment monitoring, search and rescue, hydrographic survey, and so on. Comparing with those studies on UAVs and UUVs, the one focusing on USVs was started later and has been developed quickly in the past 20 years. Since 2013, USV has advanced considerably in China, particularly in the marine survey field. Owing to its characteristics of light-weighting, intelligence, and unmanned operations, USV is attractive for shallow water, extreme environments, and marine accidents. This paper comprehensively summarizes the recent progress of the marine survey USV in China. The structure of the paper is divided into three parts. First, we briefly recall the developing history and introduce several excellent USVs of China in recent years. The marine survey USVs invested by the State Oceanic Administration (SOA) are then summarized in the next section, along with the details of hydrographic survey in the South China Sea, Antarctic marine survey, and oil spill emergency response. Finally, the paper points out current deficiencies and future directions of the potential technique.

Traditional Term

Abstract Pesantren are often associated with backwardness and traditionalism in everything: facilities, technology, learning methods, and even the curriculum. For now, it seems like the traditional term for pesantren is no longer relevant enough. The pace of movement in the era of renewal marked by the rapid development of technology has demanded pesantren to make adjustments. However, on the one hand, when viewed from the direction of change, the reform efforts pursued by pesantren are not to erase the old tradition, but merely to add something new so that the old tradition and conditions can be maintained while accepting the presence of a new one. On the other hand, the reform efforts undertaken by pesantren have implications for the fact that the typical values of the pesantren are fading away. Abstrak  Pesantren seringkali diasosiasikan dengan keterbelakangan dan tradisional dalam segala hal: fasilitas, teknologi, metode pembelajaran, dan bahkan kurikulumnya. Untuk saat ini, sepertinya istilah tradisional untuk pesantren, sudah tidak lagi cukup relevan. Laju gerak pembaharuan zaman yang ditandai dengan pesatnya perkembangan teknologi telah menuntut pesantren untuk melakukan penyesuaian diri. Kendatipun demikian, di satu sisi, jika dilihat dari arah perubahan, upaya pembaharuan yang ditempuh pesantren tidaklah untuk menghapus tradisi yang lama, tetapi sekadar menambah dengan sesuatu yang baru sehingga tradisi maupun kondisi yang lama bisa dipertahankan sambil menerima kehadiran yang baru. Di sisi yang lain, upaya pembaharuan yang dilakukan pesantren ternyata berimplikasi pada kenyataan akan semakin pudarnya nilai-nilai khas yang dimiliki oleh pesantren.

The Impact

In the context of the rapid development of urbanization and increasing population mobility in China, the outbreak of COVID-19 has had a significant impact on China’s economy and society. This article uses China UnionPay transaction data and takes Hubei, the worst-hit region by COVID-19 in China, as an example, to conduct empirical analysis using the generalized method of moments (GMM) of the impact of current urbanization patterns on the spread of the epidemic and economic recovery from the perspectives of time, industry, and regional differences. The study found that during the different stages of COVID-19, including discovery, outbreak, and subsidence, the overall impact of urbanization on the economy in Hubei Province was first positive, then became negative, and finally gradually increased. This process had significant industrial and urban heterogeneity, which was mainly manifested in losses in tourism and catering industries that were significantly greater than those in the audio-visual entertainment and digital office industries. Similarly, the recovery speed of large cities was lower than that of small and medium-sized cities. The main reason for these differences is that the one-sided problem of urbanization is more obvious in areas with higher urbanization rates. COVID-19 has drawn attention to the development of urbanization in the future, that is, the development path of one-sided economic resource agglomeration and scale expansion should be abandoned, with greater attention paid to the improvement of service functions and the development of amenities. This transformation is necessary to enhance urban economic resilience and reduce public health risks.

Topological Theories

The recent progress of modern algebra in analysing, from the algebraic standpoint, the foundations of algebraic geometry, has been marked by the rapid development of what may be called ‘analytic algebra’. By this we mean the topological theories of Noetherian rings that arise when one uses ideals to define neighbourhoods; this includes, for instance, the theory of power-series rings and of local rings. In the present paper some applications are made of this kind of algebra to some problems connected with the notion of a branch of a variety at a point.

The rapid development of mobile phones and communication networks is profoundly changing the lives of people in China. With the gradual growth of Wi-Fi on college and university campuses, Chinese schools are setting off a wave of teaching reform combining online material with traditional classroom instruction. We adapted a Chinese University massive open online course physiology course into a private university online course, specifically designed for second-semester bachelor’s level nursing students at Taishan Medical University. This online course blended with classroom teaching was offered to 108 freshmen from two parallel reform classes. A third class of 55 students was offered the traditional classroom lecture-based course as a control. Impressive teaching effects were achieved in reform classes, as indicated by significant improvement in student performance on the final examination and positive student feedback. The student surveys showed that 68% of students preferred the blended course over traditional classroom courses. The most highly rated advantages of the blended course were flexible learning time (84%) and improvement of independent study skills (75%). As higher education enters the internet era, exploiting the high-quality cyber resources may be the fastest and most economical way to improve teaching efficiency and enhance students’ study experience.

The rapid development of information technologies and their penetration into various spheres of human activity cause a sharply increased demand for IT specialists, in many countries of the world far exceeding the supply on them. High rates of technological transformation contribute to the diversification of the IT segment of the labor market, on the one hand, stimulate the disappearance of some and the emergence of new IT specialties, on the other. This creates a discrepancy between the structure of IT-related education and the labor market demand for IT specialists of the required profile and determines the relevance of developing methods for assessing the demand for IT specialties. This article is devoted to the study and solution of the problem of identifying the demand for IT specialties in the absence of accurate and complete information about the situation in the IT market segment. For the assessment of IT specialties and their ranking by the degree of demand in the labor market, the tasks of making individual and group decisions in the context of fuzzy initial information are formulated and solved. The methodological basis of the tasks posed is multi-criteria decision support methods based on fuzzy relations of expert preferences. The proposed approach as a mathematical tool for minimizing the structural imbalance of supply and demand for IT specialties is one of the components of the system of intellectual management of the labor market of IT specialists. The latter is designed to support the adoption of scientifically based management decisions to eliminate the mismatch of supply and demand in the IT segment of the labor market in professional, quantitative and qualitative sections.

A fejlesztéspolitikában ma a „smart” címkével minden vonzóbb, eladhatóbb, a kifejezés sokszor a ’környezetbarát’ vagy ’fenntartható’ szinonimájaként is használatos. A városfejlesztésben az utóbbi idők egyik legfelkapottabb paradigmája, globális szintű versengést indítva mind a városok, mind az érdekelt vállalatok között a kölcsönösen hasznosnak vélt előnyök reményében. A szerzők egyrészt annak jártak utána, miért éppen most virágzott fel a smart city mint fejlesztési paradigma, és milyen tényezők indukálták gyors előretörését. Másrészt a nemzetközi példák bemutatásán keresztül arra a kérdésre keresik a választ, milyen társadalmi hatásokkal járnak ezek a fejlesztések, milyen kihívásokkal kell szembenézni a smart city fejlesztések kapcsán, és vajon a jövőben a fejlesztési szereplők képesek lesznek-e tanulni hibáikból, és tudatosan tervezni a hatások összességével. --- Do smart cities intensify social exclusion? In development policy everything seems to be more attractive and marketable when labelled ‘smart’; the expression is often used even as a synonym for ‘environmentally-friendly’ or ‘sustainable’. Considering urban development projects, smart city development is one of the most popular paradigms, triggering global competition between cities as well as the interested companies, both expecting mutual benefits from the co-operation. The article, on the one hand, tries to reveal, why the smart city paradigm has now started to thrive, and what factors played a part in its rapid development. On the other hand, through the presentation of international practices, the authors intend to answer what social impacts these developments have had, what challenges have the smart city developments met, and whether in the future the actors could learn from their mistakes and consciously take into account the complexity of impacts.

The article analyses the main provisions of the peasant reform in Georgia, which had a further impact on the socio-economic development of the landowner peasants of Tiflis and Kutaisi provinces in the last quarter of the 19th – the early 20th centuries. On the basis of archival sources and literature, the author considers the reasons for the difficult economic situation of the Georgian landowners in the period under study. An analysis makes it possible to conclude that the socio-economic relations that had been formed in Georgia determined the contradictions inherent in the capitalist mode of management. On the one hand, the peasant reform contributed to the more rapid development of the capitalist mode of production in the countryside, laying the foundation for economic development in agriculture, the introduction of commercial agriculture, the growth of agricultural productivity, and the maturation of commodity-capitalist relations. On the other hand, the main means of production were in the hands of the landlords, which led to an even greater extensive impoverishment of the landlord peasants. Thus, in Georgia, the remnants of serfdom survived even longer than in the European provinces of the Russian Empire. It is concluded that the reason for these remnants included the backwardness and relatively weak development of capitalist relations in the South Caucasus, in particular, in Georgia.

<span>Nowadays, with the advences in ICT and rapid development of mobile internet; media information shared on the various communication networks requires the existence of adequate security measures. Cryptography becoming an effective way to meet these requirements and for maintain the confidentiality. However, communicating with encrypted messages requires secret key exchange, which is a part of a complex protocol. In this paper, we propose a new method for exchanging key based on Diffie-Hellman protocol and image registration with fast fourier transform, the principle of this method consists to concealing the key in a set of transformed images. Therefore, image registration allows finding transformations between images, which become a tool for recovering the key by the receiver.</span>

On the one hand, in the environment of the Pesantren salaf community, a kind of environment and tradition is formed which shows its unique, even unique characteristics, which are only understood by the community. Gus Dur, in this case, stated that the Pesantren salaf community is a community that has its own subcultural in the middle of society with the complexity of the problems in it. But on the other hand, there is a very rapid development of science and technology, so it demands pesantren salaf to make changes to adjust to the times, both in terms of the education system, the boarding school environment, institutions, leadership patterns, and others. Therefore, the study contained in the title "Pesantren Salaf: Social Change and Sublimation of Identity (Pesantren Model in West Java)", is very important to be carried out.The purpose of this study is none other than to find the concept of changes that occur in Pesantren salaf in West Java. For more details, they are: 1) uncovering the factors that drive changes in pesantren in West Java; 2) reveal pesantren's efforts in facing the challenges of the times, and 3) find forms of changes that occur in the Pesantren salaf in West Java.This research departs from a thought that social change will occur due to four things. First, Evolution. This theory states that humans as part of a cultured society will naturally develop gradually from simple forms to complex and perfect stages. Second, Conflict. This theory strongly believes that change will only occur if there is conflict. Third. Functional Theory. Social change occurs because of the disharmony between cultural elements. Fourth, Cycle Theory. Social change by itself will occur and cannot be controlled.The method used in this research is descriptive. In the process, the data is collected and compiled. After the data is collected and arranged in such a way, the authors analyze it and provide interpretation, with a qualitative approach. So that it is expected to be able to uncover the realities of the Pesantren salaf which are changing in the community.The results of the study stated that the Pesantren salaf can adapt well to social change by bringing up certain identities. This shift in identity needs to be examined and studied through the theory of action put forward by Max Weber. First, zweckrational. This theory is known as rational-purpose. In doing something always with a good and accurate calculation. Second, wertrational or rational-values. The involvement of the subject is directly involved in matters of absolute importance. The four traditionalists. This theory of action rests on established and established customs or traditions. Traditionalist theories respect existing authority.

This article examines the basis of legal regulation and Internet censorship in China. The genesis, development and relevant regulatory basis of legal regulation of Internet in China is examined. The author comes to the conclusion that on the one hand, Internet in China is subject to tight control due to the rapid development of technologies of observation and increase of police access to user data. Currently, China is one of the leaders in engineering and export of automated instruments for monitoring social networks. The citizens face restrictions based on the control of login accounts that give access to the Internet; blockchain apps and their developers are also subject to control and must provide registration of real names of the users; international corporations, such as Apple, Microsoft, Linkedin, are forced to bend to the demands of Chinese authorities and help to determine and punish the users who do not adhere to the censorship requirements in China. On the other hand, Chinese government makes everything possible for the large scale implementation of information technologies into socioeconomic life of the country, namely industrial and commercial sectors. Usage of internet in the sphere of sociopolitical life restricted, since China justifiably sees a threat to political stability and social security of the country.
