The PISA(Program for International Student Assessment), an international comparative study supervised by OECD, aims at producing reliable and internationally comparable indicators of students' literacy in reading, mathematics, and science. In mathematical literacy, Korean students ranked the 2nd out of the 32 participating countries in PISA. This result is very encouraging in the sense that the scores in the mathematical literacy are a forecasting indicator for the mathematical level of future citizens who are supposed to lead their countries in every field. However, Korean students showed the largest gender difference in mathematical literacy, indicating that male students achieved significantly higher scores than female counterparts. With the consideration that mathematics plays a key role in determining the overall achievement level and influences on the long-term career opportunities, it is necessary to pay more attention to the gender difference in mathematical literacy, and make an effort to reduce it to enhance the overall intelligence level of Korean human resources.

The global process of transition from industrial to information society, as well as socio-economic changes taking place in Ukraine, require significant changes in many areas of state activity. It is especially connected with the reforms in the sphere of education. Today, national programs provide for the development of education on the basis of new progressive concepts, the introduction of the educational process of new pedagogical technologies and scientific achievements, the creation of a new system of information education, entrance of Ukaine into the transcontinental computer information system. Information technologies are qualitatively changing the key resources of development: this is no longer a space with fixed production, but primarily mobile finance and intelligence. They have a direct impact on the formation of personal growth, professional content and self-organization, emotional and psychological maturity and consciousness, and so on. One of the main factors in ensuring the stability and social education of the country's citizens is the culture of security, the formation and development of which is an urgent problem today. Comprehensive and systematic development of security culture will significantly increase the readiness of the population, the level of environmental, labor and patriotic education, reduce human losses, material damage from emergencies. Ecological education can be carried out more successfully only gradually and in accordance with the socio-psychological periods of one's development: kindergarten - school - college - university. The creation of such a system of environmental education should be enshrined as the basis of state environmental policy as a constitutional norm with the usage of information technology. Graduates of universities, who are the future of our country, after mastering the skills of basic environmental education must have a high level of environmental culture, which is, in turn, part of general human culture, and investigate environmental issues from the standpoint of their profession. It is known that with the help of environmental education the collective intelligence of society is formed, which can predict human activities and processes occurring in nature, and in some way to help with the elimination of crises. It is through environmental education that another system of human values is being formed, which places great emphasis on intangible wealth and solidarity, and great responsibility of humanity for the ecological state of the native country; provides a higher standard of living as a result of sustainable development, through the introduction of information technology in this system. To improve the quality of life, we need better knowledge, which must be implemented through information technology at the international level.

구문 트리의 구조적 정보는 문장 수준 관계 추출을 수행하는데 있어 매우 중요한 자질 중 하나다. 기존 관계 추출 연구는 구문 트리에서 최단 의존 경로를 적용하는 방식으로 관계 추출에 필요한 정보를 추출해서 활용했다. 그러나 이런 트리 가지치기 기반의 정보 추출은 관계 추출에 필요한 어휘 정보를 소실할 수도 있다는 문제점이 존재한다. 본 논문은 이 문제점을 해소하기 위해 개체 중심으로 구문 트리를 재구축하고 모든 노드의 정보를 관계 추출에 활용하는 모델을 제안한다. 제안 모델은 TACRED에서 F1 점수 74.9 %, KLUE-RE 데이터셋에서 72.0%로 가장 높은 성능을 보였다.

With the steady development of Artificial Intelligence (AI), online stores are adopting chatbot services as virtual shopping assistants. This study proposes the concept of para-social presence to explore the undiscovered role of fashion chatbots' emotional and relational characteristics on service acceptance. Based on the Technology Acceptance Model (TAM), this study investigates the effect of a chatbot's para-social presence on service acceptance intention through consumers' beliefs. The web-based experiment was conducted on adult consumers who experienced chatbot services in an online shopping situation. A total of 247 responses were analyzed using confirmatory factor analysis, structural equation modeling, and multi-group SEM by AMOS 21.0 and SPSS 23.0. The findings illustrate that the chatbot's intimacy positively influenced consumers' perceived enjoyment, while the chatbot's understanding had a significant effect on perceived usefulness and ease of use. The chatbot's involvement had a positive effect on all consumer beliefs. Moreover, perceived ease of use had a positive influence on usefulness. A greater level of perceived usefulness and enjoyment positively heightened consumers' service acceptance intention. This study also verifies the moderating role of a need for human interaction. Consumers with a high need for human interaction have a relatively low tendency to perceive chatbot services as useful.

The Avatar robot, which is one of the teleoperation robots, aims to enable users to feel the robot as a part of the body to intuitively and naturally perform various tasks. Considering the purpose of the avatar robot, an end-effector identical to a human hand is advantageous, but a robotic hand with human hand level performance has not yet been developed. In this paper we propose a new 3-finger robotic hand with human-avatar hand posture mapping algorithm which were integrated with TOCABI-AVATAR, one of the teleoperation system. Due to the flexible rolling contact joints and tendon driven mechanism applied to the finger, the finger could implement adaptive grasping and absorb the impact force caused by unexpected contacts. In addition, human-avatar hand mapping algorithm using five calibration hand postures propose to compensate physical differences between operators. Using the TOCABI-AVATAR system with the robotic hands and mapping algorithm, the operator can perform 13 out of 16 hand postures of grasping taxonomy and 4 gestures. In addition, using the system, we participated in the ANA AVATAR XPRIZE Semi-final and successfully performed three scenarios which including various social interactions as well as object manipulation.

As Daniel Bell says, that modern society is an information society. In contrast to earlier days, modern society has placed a high value on information and knowledge. Therefore, modern civilization depends largely on information and knowledged, which is the most valuable sources of all intelligence activities. By coordinating a large number of human action, the information creates a powerful social tool. It combines its personnel with its resources and new materials at various level. At the same time, It continually evaluates how well it is performing and tries to adjust itself accordingly in order to achieve social goals. As we shall see, all this allows information to sew the various needs of society. In connection with above mentioned problem consciousness, the study is designed to sew the following purposes. As its title indicates, and perhaps most significant. This study is to review and reinterpret the existing literature on local telecommunication system, networks, and policy direction in order to arrive at a somewhat more general approach to understanding them. In local telecommunications service, the service exploitation and promotion and database development must be accomplished by establishing local telecommunications. If we develop local telecommunications toward the progressing direction, we would dissolve the regional information disparity and could also make the local policy suited for high-intelligence society. It is true of any science that knowledge is never complete. It is also true of a science that knowledge should grow, through systematic reexamination of the body of findings. There are certainly true of this study on the developmental direction for local telecommunication system.
