The purpose of this article is to problematize the existence of a possible Ibero-American informational thinking. It was initially observed that a relative absence of Ibero-America in the international presentations and mappings of information science exists. Below, the reality of the 22 countries that compose Ibero-America is discussed, a region that can be understood from a sociocultural and geopolitical perspective. Then, a mapping of the information science research in these countries is made. The main research topics found are: epistemological studies, relationships with library science, information literacy, representation and organization, bibliometric studies, information management, user studies, technological dimensions, and relationships with archival science and museum studies. Finally, a general epistemological configuration of information science is presented at a global level, highlighting the great trends of study of information that marked the decades of the 1960s and 1970s (physical model), 1980s and 1990s (cognitive model), and the 21st century (sociocultural model), and which manifested themselves in the different subareas that make up the field. The most recent research in information science, in addition to addressing information transfer (physical dimension) and its relationship with data and knowledge (cognitive dimension), has also incorporated aspects related to the social effects of information, its role in the constitution of identities and culture, and the importance of its material conformations. Such expansion reflects attempts to address the complexity of informational phenomena. Therefore, it is concluded that it is important to place the specific contributions of Ibero-America in this context.

With the application and promotion of biometric technology, biometrics has become more and more important to identity authentication. In order to ensure the privacy of the user, the biometrics cannot be stored or manipulated in plaintext. Aiming at this problem, this paper analyzes and summarizes the scheme and performance of the existing biometric authentication system, and proposes an iris-based ciphertext authentication system based on fully homomorphic encryption using the FV scheme. The implementation of the system is partly powered by Microsoft's SEAL (Simple Encrypted Arithmetic Library). The entire system can complete iris authentication without decrypting the iris feature template, and the database stores the homomorphic ciphertext of the iris feature template. Thus, there is no need to worry about the leakage of the iris feature template. At the same time, the system does not require a trusted center for authentication, and the authentication is completed on the server side directly using the one-time MAC authentication method. Tests have shown that when the system adopts an iris algorithm with a low depth of calculation circuit such as the Hamming distance comparison algorithm, it has good performance, which basically meets the requirements of real application scenarios.

The web-based project is seriously not efficient area at software engineering. In order to develop a web-based system, UI(User Interface) designers usually first design display layout and then business logic developers bring to complete the coding of the display layout source. In the case of maintenance, it goes through the same process, This kinds of web-based software development method were proposed by the various methods same as the tag library of JSP, But there are many problems to apply them and they are low productive comparing to the CIS based software development method, WFS(Neb Form System), which is suggested on this thesis, separates UI design from business logic on a web project and offers the better environment to develop web based software, Eventually WFS will improve the productivity to develop web based software.

This paper introduces Stuxnet, a malicious ware that presently stimulates severity of the cyber warfare worldwide, analyses how it propagates and what it affects if infected and proposes a process to cure infected systems according to its organization. Malicious wares such as Stuxnet secretes themselves within the system during propagation and it is required to analyze file hiding techniques they use to detect and remove them. According to the result of the analysis in this paper, Stuxnet uses the library hooking technique and the file system filter driver technique on both user level and kernel level, respectively, to hide its files. Therefore, this paper shows the results of the Stuxnet's file hiding approach and proposes an idea for countermeasure to neutralize it. A pilot implementation of the idea afterward shows that the stealthing techniques of Stuxnet are removed by the implementation.

This article is a part of a doctoral research project on developing the faculty-librarian collaboration model to support learning and research at Vietnamese universities. The findings of this study have crucial significance in drawing a broader view of the importance of faculty-librarian collaboration and the roles of such collaborators at Vietnamese universities. Qualitative methodology was used to formulate related topics and achieve these research objectives. Semi-structured interviews were carried out at four universities in Vietnam with three key informants, including the faculty, librarian, and administrators (dean/vice dean of faculty, director/deputy director of the library). From March to April 2019, researchers conducted 29 interviews with three participant groups. The striking results of this research showed that the faculty and librarians realized the significance of a collaborative relationship and expect that Vietnamese universities will design and deploy a model to boost the effectiveness of this collaboration. Besides this, the study found that the collaborators play certain important roles within the collaborative relationship, for instance, that of reference, coordinator, special lecturer, cooperator, and information user.

본 논문은 교통 신호 제어 알고리즘들의 성능을 비교하기 위한 복합교차로 시뮬레이터를 구현하였다. 기존의 교통 시뮬레이터들은 단일교차로를 대상으로 하거나 텍스트 모드로 동작하는 경우가 많았다. 논문의 시뮬레이터는 Visual C++의 MFC 라이브러리를 사용하여 n $\times$ n 형태를 갖는 복합교차로에 적합하도록 객체지향적으로 구현되었으며, 성능 비교를 위하여 제어 알고리즘들을 별개의 윈도우에서 처리하기 쉽도록 MDI 방식을 사용하였다. 개발한 시뮬레이터는 그래프 윈도우와 맵 윈도우의 편리한 사용자 인터페이스, 논리시간 설정을 통한 다목적 시뮬레이션, 다양한 성능평가 출력 등의 특징을 갖는다. Abstract In this paper, we implemented a multiple crossroad simulator to evaluate the performance of the traffic signal control algorithms. Most of existing traffic simulators were operated in text-mode or at a single intersection. We developed the object-oriented simulator suitable for multiple crossroads with n $\times$ n intersections by using MFC (Microsoft Foundation Class) library in Visual C++. The simulator was implemented by using MDI (Multiple Document Interface) scheme in order to process both control algorithms in separate windows respectively. Our simulator has the following features: user friendly interface with graph window and map window, multi-purpose simulations by setting logical time, and various forms of performance evaluation.

As a preliminary step to build a complete superyacht hull design program, the development of superyacht profile design system is introduced. The two-dimensional hull profile is decomposed into four local zones depending upon the functionality and connecting continuity of the profile. Characteristics of each zone are investigated and used to generate the model describing the geometric shape of zone using freeform curves. A set of design parameters is derived from the established geometric model. Generation and modification of a model are is by manipulating the chosen parameters. Four zones designed are integrated to form a final profile. An interactive design system performing all the modeling and modification processes is implemented using the graphic user interface system based an Microsoft Foundation Class and OpenCASCADE, a open graphic library. The shapes of the profiles generated by the developed design system are verified with those of built superyachts. The developed design system will be used for the construction of three-dimensional superyacht hull modeling system.

In this paper, CPLD low power technology mapping using reuse module selection under the time constraint is proposed. Traditional high-level synthesis do not allow reuse of complex, realistic datapath component during the task of scheduling. On the other hand, the proposed algorithm is able to approach a productivity of the design the low power to reuse which given a library of user-defined datapath component and to share of resource sharing on the switching activity in a shared resource Also, we are obtainable the optimal the scheduling result in experimental results of our using chaining and multi-cycling in the scheduling techniques. Low power circuit make using CPLD technology mapping algorithm for selection reuse module by scheduling.

In the social information facilities with physical stacks, it is critical to arrange categories of knowledge since there should be conventional methods by which users and visitors can browse index of all sorts of media relating to their topics. The classical index system of knowledge has been developed with primitive libraries and museums and therefore the system can be addressed by analyzing typical cases of precedents. As the forth industrial revolution has emerged, there will be quite innovative approach to provide information to the public as well as the private. The coalition between knowledge and space has always been considered as essential characteristics that remind scholars of hierarchical layout of knowledge resources such as maps, books, documents and diverse specimens. This research assumes that the spatial layout of knowledge can be classified in terms of physical attributes, symbolic entities, and information media and it defines what coalition between knowledge and space is creative in order to enacting interactive dialogue among information navigators. The spaces in between the knowledges function as trasition areas where the index system informs and stimulates, where the interface between the different knowledges is optimized and therefore the library as the public facilities no longer dedicated to the text, but as an information space in which all sorts of media are distributed equally.

The article is based on a model, in the context of which there are two fundamental building blocks of basic library skills and skills in the use of information technology. The former are formed within the framework of educational programs for users of academic libraries, the latter are formed within the framework of initiatives such as the European Computer Driving License. Between the basic and the highest levels of the concept of "information literacy" there are seven heading skills and attributes, the repeated practice of which leads from the position of a competent user to an expert level of reflection and critical awareness of information as an intellectual resource. Freshmen will likely be at the beginning of the arrow, probably practicing only the first four skills, while graduate students and young scientists will be closer to the end and will use seven skills.
