Performing Cache Timing Attacks from the Reconfigurable Part of a Heterogeneous SoC—An Experimental Study

Cache attacks are widespread on microprocessors and multi-processor system-on-chips but have not yet spread to heterogeneous systems-on-chip such as SoC-FPGA that are found in increasing numbers of applications on servers or in the cloud. This type of SoC has two parts: a processing system that includes hard components and ARM processor cores and a programmable logic part that includes logic gates to be used to implement custom designs. The two parts communicate via memory-mapped interfaces. One of these interfaces is the accelerator coherency port that provides optional cache coherency between the two parts. In this paper, we discuss the practicability and potential threat of inside-SoC cache attacks using the cache coherency mechanism of a complex heterogeneous SoC-FPGA. We provide proof of two cache timing attacks Flush+Reload and Evict+Time when SoC-FPGA is targeted, and proof of hidden communication using a cache-based covert channel. The heterogeneous SoC-FPGA Xilinx Zynq-7010 is used as an experimental target.

Évaluation des impacts d’une infrastructure de données satellitaires

Cet article propose un cadre exploratoire d’évaluation des impacts économiques des Infrastructures de Données Géographiques et Spatiales (IDGS) à partir de l’exemple de GEOSUD et des cartes de coupes rases relatives à la gestion des forêts. L’évaluation est réalisée à partir d’une enquête en ligne auprès des services du ministère de l’Agriculture chargés du contrôle des coupes rases réalisés par les exploitants forestiers. L’approche développée croise deux points de vue complémentaires. Elle s’inscrit, d’une part, dans une logique économique pour estimer certains effets à l’échelle de la chaîne de valeur concernée par la fabrique et l’usage de l’information satellitaire, des produits et services thématiques dérivés. Les effets mesurés portent sur les économies de coûts et de productivité, la valeur ajoutée créée à l’échelle de la chaîne de valeur liée à ces cartes de coupes rases. Au total, il apparaît que pour un euro dépensé pour le fonctionnement de l’IDGS (hors investissement initial), la valeur ajoutée créée directement et indirectement s’élève au maximum à 63 € et les coûts de transactions évités à 24 €. Elle s’inscrit, d’autre part, dans une logique gestionnaire pour appréhender les effets des IDGS liés aux processus d’innovation à l’échelle d’une communauté de pratiques. Elles permettent en effet des gains de coordination et de mutualisation pour co-construire des connaissances conduisant à de nouveaux produits et/ou procédés. L’étude montre que près des deux-tiers des structures enquêtées ont observé des effets qualitatifs en termes de mise en réseau et un renforcement des compétences lié aux formations et aux services d’accompagnement offerts par la plateforme GEOSUD. Des effets qualitatifs sur les propriétés des politiques forestières et plus généralement sur les dynamiques de développement territorial ont aussi été appréhendés.

App for smartphone for detecting fungus diseases of plant leaves

The symptoms and biophysical processes occurring in garden strawberry plants when they are affected by the dominant type of disease (up to 80%) caused by pathogenic fungi have been described. The ineffectiveness of the visual assessment of the degree of damage to strawberry diseases by a conventional 5-point scale or as a percentage of the leaf plate area affected by fungi, with the involvement of qualified specialists, has been shown. To create diagnostic tools that allow early detection of fungal diseases of garden strawberries, one of the methods of computer vision was proposed by counting image pixels in the space of color channels of red, green and blue (R, G, B), which makes it possible to determine the degree of fungal diseases affecting an individual plant leaf. The algorithm includes capturing an image with a digital camera by focusing on a plant leaf placed on a substrate with a uniform background providing a contrasting selection of the object; converting a color image to black and white; dividing the image between areas with necrotic spots and healthy areas of the plant leaf by masking and removing pixels; counting the number of pixels in these two areas and calculating their ratio. Information about a computer software for determining the degree of damage to a strawberry leaf by garden fungal diseases has been given. Java programming language (operating system Android Studio 3.4.1) was used as a language for the development of the logical part of the information system. In order to build a graphical interface, the software facilitating the development and integration of various modules of the LibGDX software project was used. The proposed algorithm is implemented for a personal computer and can be installed on a smartphone in the form of a software application, with the help of which any agricultural producer can carry out early diagnosis of fungal plant diseases.

Mutation of the Seaside Architecture in Algeria and its Impact on Coastal Landspace. A Case Study: Ain El Turc, Algeria

The sea strongly contributes to the identity of coastline areas. Moreover, it has been demonstrated that the coastline is a geographical entity which calls for specific organization. From an architectural point of view, design elements have been associated with the assets (or constraints) of the site. Thus, the view is associated with the bow window, protection against the climate with canopies and protruding roofs, and quality of the soil and bedrock. Integration into the site is also highly desirable, both in form (ship) and in construction materials. The urbanization of coastal areas in Algeria is a colonial fact. In pre-colonial times, little importance was given to these areas, whereas later they became a priority: port sites, the speed of communications with Europe, rich agricultural plains, a mild climate and welcoming beaches. The developments and seaside constructions carried out during this period were part of the logic of attractiveness to welcome more European settlers and promote the sedentarization and growth of those already living in Algeria. After independence, political and economic choices did not unfortunately take into account the geographical and climatic specificity of Algeria’s coastal zones. Thus, population growth and rural depopulation have led to a sharp increase in the demand for real estate, which has resulted in unbridled urbanization, regardless of the seaside vocation of these territories. In this article, based on the case of the seaside resort of Ain El Turc, which has colonial architectural production of an exceptional quality that takes into account the specificities of the coastline and the presence of the sea, the aim is to assess and verify if this architecture was perpetuated after independence. To this end, we have highlighted, through bibliographic research, the characteristics of seaside architecture from the 19th and 20th centuries and those of the contemporary time. An analysis of all the dwellings located in the Saint Rock district in the municipality of Ain El Turc consisted in identifying these characteristics and establishing a classification of these constructions.

Evaluation of Covid-19 vaccines: Pharmacoepidemiological aspects

The marketing authorization granted to SARS-Cov-2 vaccines was accompanied by reinforced safety monitoring plans. These plans’ implementation was part of the usual logic of post-marketing surveillance of new and innovative health products. It was especially adapted to the context of post-marketing monitoring of drugs developed according to the usual scientific quality standards but in an accelerated schedule. In Europe, the reinforced surveillance system relies on the complementary strengths of pharmacovigilance and pharmacoepidemiology. If the performances of pharmacovigilance monitoring are incomparable for the detection of safety signals relating to rare events of atypical presentation, it needs to be completed with pharmacoepidemiology activities for more common events, either multifactorial or frequently classified as idiopathic. The pharmacoepidemiological monitoring developed in Europe was elaborated before the first SARS-Cov-2 vaccines where marketed, taking into account the lessons learned from the vaccination campaign against 2009 A (H1N1) influenza. It includes numerous academic studies as well as studies performed within vaccines risk management plans. In terms of safety, those defined a priori mostly concerns a list of pre-established health events of specific interest. Aside of these planned activities, ad-hoc studies will be latter developed on purpose to investigate safety signals or potential signals that could be identified as the result of pharmacovigilance activities. Aside of these regulated activities, as for today, very few studies have been published regarding SARS-Cov-2 vaccines; most of the existing consist in preprints that should be considered with caution. Pharmacoepidemiology of vaccines is thought to allow near-real time monitoring that needs sufficient time to provide with valid results. In the constant urge for information that accompanies COVID-related science, it is important not to make haste the enemy of speed and to let pharmacoepidemiology provides with what it is expected to do: rock-solid scientific information contributing to evidence-based decision-making.

Automatic adjustment of tire inflation pressure through an intelligent CTIS: Effects on the vehicle lateral dynamic behavior

The paper investigates the effect of tire inflation pressure on the lateral dynamics of a passenger car, and presents a possible control-oriented methodology aimed at adapting tire pressure to the current vehicle loading condition targeting a reference characteristic. Starting from the tire characteristics at several inflation pressure levels, the paper investigates the effect of changing selectively tire pressure on each of the two axles, through theoretical calculation of the curvature gain based on the computation of the derivatives of stability, and compares the obtained sensitivity to the results of a multibody simulation model validated through on-track tests. Finally, the work presents a possible algorithm that could be implemented on-board vehicle ECU to provide, for the current loading condition of the vehicle, a tire pressure combination that targets a specific lateral dynamics characteristic. The algorithm is intended as part of the control logic of an intelligent Central Tire Inflation System (CTIS) able to adjust automatically tire pressure according to the actual vehicle working conditions.

High Level Synthesis Optimizations of Road Lane Detection Development on Zynq-7000

In this work, we proposed High-Level Synthesis (HLS) optimization processes to improve the speed and the resource usage of complex algorithms, especially nested-loop. The proposed HLS optimization processes are divided into four steps: array sizing is performed to decrease the resource usage on Programmable Logic (PL) part, loop analysis is performed to determine which loop must be loop unrolling or loop pipelining, array partitioning is performed to resolve the bottleneck of loop unrolling and loop pipelining, and HLS interface is performed to select the best block level and port level interface for array argument of RTL design. A case study road lane detection was analyzed and applied with suitable optimization techniques to implement on the Xilinx Zynq-7000 family (Zybo ZC7010-1) which was a low-cost FPGA. From the experimental results, our proposed method reaches 6.66 times faster than the primitive method at clock frequency 100 MHz or about 6 FPS. Although the proposed methods cannot reach the standard real-time (25 FPS), they can instruct HLS developers for speed increasing and resource decreasing on an FPGA.

A Low-Power 12-Bit 20 MS/s Asynchronously Controlled SAR ADC for WAVE ITS Sensor Based Applications.

A low power 12-bit, 20 MS/s asynchronously controlled successive approximation register (SAR) analog-to-digital converter (ADC) to be used in wireless access for vehicular environment (WAVE) intelligent transportation system (ITS) sensor based application is presented in this paper. To optimize the architecture with respect to power consumption and performance, several techniques are proposed. A switching method which employs the common mode charge recovery (CMCR) switching process is presented for capacitive digital-to-analog converter (CDAC) part to lower the switching energy. The switching technique proposed in our work consumes 56.3% less energy in comparison with conventional CMCR switching method. For high speed operation with low power consumption and to overcome the kick back issue in the comparator part, a mutated dynamic-latch comparator with cascode is implemented. In addition, to optimize the flexibility relating to the performance of logic part, an asynchronous topology is employed. The structure is fabricated in 65 nm CMOS process technology with an active area of 0.14 mm2. With a sampling frequency of 20 MS/s, the proposed architecture attains signal-to-noise distortion ratio (SNDR) of 65.44 dB at Nyquist frequency while consuming only 472.2 µW with 1 V power supply.

PUF-RAKE: A PUF-Based Robust and Lightweight Authentication and Key Establishment Protocol

Physically unclonable functions (PUFs) bind a device's identity to its physical hardware and thus, can be employed for device identification, authentication and cryptographic key generation. However, PUFs are susceptible to modeling attacks if a number of PUFs’ challenge-response pairs (CRPs) are exposed to the adversary. Furthermore, many of the embedded devices requiring authentication and inter-device communication in a real-time environment/system have stringent resource and low latency requirements, and thus require a lightweight authentication and key establishment mechanism to quickly realize an authenticated and secure connection. We propose PUF-RAKE, a PUF-based lightweight, highly reliable authentication and key establishment scheme. The proposed scheme enhances the reliability of PUF as well as alleviates the resource constraints by employing error correction in the server instead of the device as well as removing cryptographic hashing required by earlier PUF-based protocols. The proposed PUF-RAKE is robust against masquerade, brute force, replay, and modeling attacks. In PUF-RAKE, we introduce an inexpensive yet secure stream authentication scheme inside the device which authenticates the server before the underlying PUF can be invoked. This prevents an adversary from brute forcing the device's PUF to acquire CRPs essentially locking out the device from unauthorized model generation. Additionally, we also introduce a lightweight CRP obfuscation mechanism involving XOR and shuffle operations. The security of PUF-RAKE has been formally verified. A prototype of the protocol has been implemented on two Xilinx Zynq 7000 system-on-chips with one present on Xilinx zc706 evaluation board and the other present on the Avnet Zedboard. Observations, security analysis and results verify that the PUF-RAKE is secure against a probabilistic polynomial time adversary under both the unauthenticated link and authenticated link adversarial models while providing ∼99% reliable authentication. In addition, PUF-RAKE provides a reduction of 60 and 72 percent for look-up tables (LUTs) and register count, respectively, in the programmable logic (PL) part of the Zynq 7000 as compared to a recently proposed approach while providing additional advantages.

Korean diaspora as the subject of ethnic policy of the Republic of Kazakhstan (1991 – 2020)

This article examines Korean diaspora as the subject of ethnic policy of the Republic of Kazakhstan. The manifestations of the growing importance of national and ethnic affiliation as the identity important markers of the individuals and groups in the modern Kazakh society actualized the need for taking special measures and development of the doctrine of interaction of peoples within the multinational state. The research of the ethnic policy of the Republic of Kazakhstan through the prism of Korean diaspora allowed considering the crucial aspects and mechanisms of implementation of the state strategy of interethnic regulation. Comparison is conducted on the the legal and factual components of the work of the Assembly of People of Kazakhstan &amp;ndash; the central body for ethnic affairs. The author reviews the humanitarian initiatives of the Association of Koreans of Kazakhstan as a structural part of the Assembly. The article analyzes not only domestic legal documents, but also the report of the United Nations Independent Expert on Minority Issues. The work is divided into the following logical parts: familiarization with the key principles and principal bodies of the ethnic policy of Kazakhstan; overview of the activity of ethno-cultural Korean societies; coverage of the topics of national language; examination of representation of the diaspora in different government branches and structures. This work is first to conduct a systematic historical research on the place and role of Koryo-saram in the ethnic policy of Kazakhstan. It is demonstrate that Korean diaspora, or Koryo-saram, is a vivid example of positive experience of the state strategy aimed at harmonization of interethnic relations. Using all necessary legal and infrastructural resources, Koreans manage to maintain and cultivate interest to their native culture, while being an organic part of Kazakhstan's democratic society.

Legal paradigm of the institutions of notarial acts in Ukraine: theoretical and practical dimensions

In the article the author studies some legal paradigms of the notary system in Ukraine as a separate institution of natural and legal entities’ rights and interests protection. It has been substantiated that the notary system of Ukraine plays an important part in law-enforcement function of the state, that protection of rights and legal interests of natural and legal entities is the main objective of the notary system. This requires improvement of the legal regulation of notary activities which is becoming more and more objective and complicated, and the development of electronic technologies should provide notary’s exercising vested powers efficiently, as well as securing legal documents ensuring timeliness and impeccable quality of notarial acts. Nowadays, the legal regulation of notarial activities is under continuous reforms. Studying the issue of transferring «paper» notary system into electronic one as well as the current development of institutions of notarial acts in Ukraine is a logical part of the notary activities research and an integral part of the notary legislation perfection allowing to give scientific evaluation of both the present legal regulation of notary activities and to outline the guidelines of its reformation. The author specifies that the use of electronic technologies in notarial activities is a complicated issues author specifies involving numerous factors of legal, organizational and technical nature. Considering the subject significance of notary institution functioning, taking into account the use of electronic technologies in notarial activities, the Ministry of Justice of Ukraine launched in 2020 the Concept of the great notarial reformation providing for: implementation of the electronic form of notariat (E-Notariat); abolition of state notaries public and transition to a uniform notary system; development of up-to-date institutions of notarial acts and self-regulation of notarial activities. It has been specified that the novel e-notarial reformation will not only broaden the authority of notaries public but also will enlarge both their scope of duties and the degree of notary institutions responsibility, as well as it will ensure the development of institutions of notarial acts . The author suggests that while reforming the Ukrainian notary system it is necessary to take into account the current development of the institutions of notarial acts in Ukraine and let the notaries public, as an independent area of notarial activities, participate in mediating conflict management; collect documents necessary for registration of legal persons; participate in meetings of legal persons’ management bodies on election (assignment) and asset management as well. The author substantiates the necessity to obsolete the quasi-notarial system. It has been suggested, besides an individual insurance of a notary public, to start the collective insurance by the Notary Chamber of Ukraine and to create the Compensation fund of the Notary Chamber of Ukraine. The author outlines the further development of the notary activities in Ukraine, their introduction into the national ideology of the country and the increase in amount and quality of notary services. Key words: notary system, notary activities, electronic technologies in notary activities, qualified electronic signature, amount and quality of notary services, notarial reformation, e-notariat.

Applications of Vedic mathematics in Algebra

Vedic mathematics is an interesting, speedy, simple logical & integral part of our ancient Indian culture using traditional mathematics, which finds its origin in our Vedas especially “Atharva Veda” and is mainly based on 16 principles called “Sutras” & 13 Sub-Sutras. Applied to almost every branch of mathematics.

Here, discuss some applications of Vedic mathematics in one of its field i.e. Algebra and see how it saves a lot of time & efforts in solving the problems.

Introductory classes for newcomer primary school students in Sweden: Pedagogical principles and emotional understanding

ABSTRACT Through the study of pedagogic discourse and practice in introductory classes (ICs) aimed at new migrant students at a linguistically diverse primary school in Sweden, we discuss pedagogic principles and power dynamics, drawing on Bernstein’s conceptual frame. Our ethnographic data consist of teacher interviews and observational fieldnotes. A compound set of pedagogic principles was found, where the acknowledgement of the students’ prior languages differs from previous research. Furthermore, the teachers’ accommodations to the students’ needs through a collaborative practice of care formed an important part of the inner logic of discourse and practice. We find this multilingual and emotional support to be contingent upon the IC teachers’ multilingual competencies and long-term experience with ICs, multilingualism and migration, and support from school management. We welcome interrelated discussions of underpinning logics based on research within different educational contexts comprising migrant students.

Organization and Management of Digital Education in Uzbekistan During the COVID-19 Pandemic

The meaning of a word is an expression of a thing in an objective being, an event and a reflection of reality in a subject. In addition, the word also has a logical part, in a figurative sense, it expresses the relationship of the subject to the object.&#x0D; The article reveals the methodological meaning of “mucha” (sema) in artistic speech, which creates a subjective attitude to the object in the figurative sense of the word, the achievement of clarity and attractiveness of speech due to the expressive and stylistic coloring in this sense. Moreover, expressive-stylistic painting is based solely on the fact that a word is expressed through a certain meaning. In artistic discourse, they also talk about the phenomena of migratory speech.&#x0D; The article analyzes existing ideas, which also focus on the study of artistic speech, as well as the author's own views on the subject.&#x0D;

КОММУНИКАТИВНЫЕ ЧАСТИЦЫ КАК СРЕДСТВА РЕПРЕЗЕНТАЦИИ АКТУАЛЬНОЙ ИНФОРМАЦИИ В ХУДОЖЕСТВЕННОМ ДИСКУРСЕ (НА МАТЕРИАЛЕ АНГЛИЙСКОГО, ИСПАНСКОГО И РУССКОГО ЯЗЫКОВ)

This article examines one of the issues of fiction discourse and communicative syntax that has not yet been sufficiently studied, i.e. the role of limiting particles in the communicative and syntactic organization of a sentence in the English, Spanish and Russian literary discourse. These particles are considered with rhetorical means which are of particular importance in literary discourse. Various lexical and syntactic constructions can be used as rhetorical means (for example, word order, lexical repetitions, inversion, etc.), as well as literary figurative forms. It is worth noting that one of the relatively understudied issues of actual syntax remains the question of communicative pragmatic functions of limiting particles, which occupy a special place in the system of linguistic means of expressing the actual division in literary discourse, and their role in the communicative and syntactic organization of a sentence in the English, Spanish and Russian languages. Communicative (actual) division is one the most important aspects of the utterance which marks, according to the particular speech situation and communicative and pragmatic intentions, logical parts of the utterance – theme and rheme, determining the meaning of the utterance as a speech unit.Actual division is seen as an individual speech act, relating to a particular situation and defined by the communicative intent of the speaker, as a phenomenon that is not subject to standardization and generalization. Several methods of actualization are simultaneously involved in forming the communicative (actual) division of a sentence, some of them being the main and others being auxiliary means which can replace, supplement or reinforce each other. Thus, each language has a fairly rich system of communication-oriented means that have received a stable and standardized character, designed specifically for expressing the communicative division of a sentence and providing the speaker (writer) an opportunity to choose the necessary ways of its implementation in accordance with a specific speech situation and the purpose of the utterance.

КТО НА КОГО ОХОТИТСЯ? ЛЕКСИЧЕСКИЙ И СЮЖЕТНЫЙ АНАЛИЗ АВЕНТЮРЫ XVI "ПЕСНИ О НИБЕЛУНГАХ"

The present article discusses the situation of a hunt in the aveture XVI of the Nibelungenlied and provides a lexical and semantic analysis of certain lexis related to the hunt. The aventure (chapter) 16 marks the border between two logical parts of the poem, the first of which ends with the murder of Sigfried (Sigird of the Norse Völsunga Saga). Burgundian royal court initiates the hunt in order to get an opportunity to murder Siegfried after the conflict between Kriemhild (Siegfried’s wife and Gunther’s sister) and Brunhild (Gunter’s wife). With the hunt being merely a pretence to bring Siegfried out of the city of Worms and leave him without his armour, the episode of the hunt does not provide many details on the of chasing the game. The armour and weapons draw more attention from the author. The murder in the forest is a mark of the German version of the tale, while the Norse one has him killed in a bedroom. However, the author of the forest episode followed an older text which had described Siegfried killing the dragon. It is possible to presume that the author have used this disappeared episode to create the hunting episode and Siegfried’s murder as it is depicted in the Nibelungenlied

The article considers the method for describing program modeling where predicates are used to create a model in the form of a nondeterministic finite automaton. A format of the description of predicates with the division of their semantic and conditional parts is offered in the paper. Arithmetic operators, parentheses, standard functions, as well as temporal logic operators U and N should be used to describe the content of the predicate. For the logical part of predicates, in addition to their logical functions, it is proposed to use relation operations, arithmetic operators, parentheses and standard functions. The formation of the description of each state of the pro-gram automaton model should be completed by dividing into different branches of the model. To describe the models of parallel programs, the following special states have been introduced: a state-monitor for the access of various processes to shared resources and a state-protocol for the description of independent parallel branches. The model is created in the process of its de-scription, so it does not require further verification. If the description of the model is performed correctly and the optimal algorithm of the future program is selected, such model will fully cor-respond to its description. Unlike MODEL CHECKING technology, which requires verification, it eliminates the need for model verification. The graph of the obtained model is processed by its sequential traversal on all branches with returns to the previous states and subsequent soft-ware implementation. Consecutive traversing should be performed for each branch of the model either to its final state or to the state that has already been processed during the traversal. Model processing includes transmission of the model description into an internal representation for subsequent conversion into a program in the target procedural programming language. In this case all actions in the substantive parts of the predicates, as well as the conditions of the branches in the process of transmission are converted into an internal representation of the pro-gram. This technology provides a direct conversion of the description of the program model in-to the program itself.

The EU–China Comprehensive Agreement on Investment: A Model for Investment Coverage in the World Trade Organization?

Historically, foreign investment policies have been a fiercely contested issue for the international trade regime. The launch of discussions on investment facilitation under WTO auspices suggests greater willingness among some WTO members to discuss investment issues. The China-EU Comprehensive Agreement on Investment (CAI) provides a possible basis for negotiating investment policy disciplines in the WTO on a plurilateral basis. While the prospects for ratification of the CAI by the EU are uncertain, the CAI provides a baseline for possible investment rules in the WTO. Investment rules anchored both against the CAI outcomes and structured on a plurilateral basis are a logical part of a WTO resuscitation strategy.

2000년 이후 독도관련 역사학 분야 연구의 성과와 향후 과제

The purpose of this study is to understand the overall tendency of Dokdo research in Korea and then to examine the current status and tasks of Dokdo research in the field of history for about 20 years since 2000. While more than 200 research institutes and related organizations in Dokdo are establishe d, Japan shows only a few research centers, and the number of researchers in Korea is about 10 times than Japan the research results are remarkably high. Nevertheless, Japan has been pushing our loopholes in terms of researc h, spreading the distorted logic of rhetoric that &quot;Dukdo is a unique territory of Japan that is obvious historically and internationally, and that Korea is currently illegally occupied&quot; in Japanese society generalizing their logic. Altho ugh more than 100 studies on Dokdo have been poured out every year, Japan's distortion claims and fictions have not been clearly objectively neutral ized over various issues. First, the Dokdo study in Korea has resulted in the research result that denies the &quot;unique territorial discussion&quot; that the Japanese government claims since 2000. This is the influence of the study by conscientious scholars in Japan and the recently increased research based on Japanese historical record. Second, there is no clear basis for criticizing the claim of the Japanese Ministry of Foreign Affairs in &quot;10 Points to understand the Takeshima proble m&quot; in relation to the issue of Dokdo sovereignty. This is a part of Japan's logic that gradually complements the blind spot, but it is necessary to complet e the logic that clearly neutralizes historical and geographical international law. Third, in the Dokdo study, it is too concentrated on specific issues such as the Ahn Yong-bok case and the time of Dokdo in 1905. In order to prove the unfairness of Japanese logic and the fiction of &quot;unique territorial debate&quot; and &quot;Terra Nullius - unpreemption theory&quot; claimed by Japan, we should find the evidence of our effective control of Dokdo as more empirical. Fourth, despite the active progress of many new studies, it is necessary to point out the problems following the existing studies and the indiscriminate citation of existing previous studies. Many studies still depend on the recopyi ng the materials from previous or existing researchers, which is a part to be self-reliant, and, it is time to study toward a new viewpoint to overcome the limitations of previous studies. This is not only the responsibility of our research climate, which is evaluate d by short-term performance and quantitative scale, but at least the Dokdo study with national pride should be directed toward a new study method out of repeating past research results. It is necessary to change the existing research and analysis method only to say the same words, or to avoid indiscri minate citation and speculative analysis on raw material interpretation.
