The relevance of the research involves outlining the need for modern professionals to acquire new competencies. In the conditions of rapid civilizational progress, in order to meet the requirements of the labor market in the knowledge society, there is a readiness for continuous training as an indicator of professional success. The purpose of the research is to identify the impact of various forms of application of information technologies for lifelong learning in order to provide the continuous self-development of each person without cultural or age restrictions and on the basis of rapid digital progress. A high level (96%) of need of the adult population in continuing education with the use of digital technologies has been established. The most effective ways to implement the concept of "lifelong learning" have been identified (educational camps, lifelong learning, mass open online courses, Makerspace activities, portfolio use, use of emoji, casual game, scientific research with iVR game, implementation of digital games, work in scientific cafes). 2 basic objectives of continuing professional education for adults have been outlined (continuous improvement of qualifications and obtaining new qualifications). The features of ICT application in adult education have been investigated by using the following methods, namely: flexibility in terms of easy access to ideas, solving various problems, orientation approach, functional learning, group or individual learning, integration of leisure, personal and professional activities, gamification. The advantages of application of information technologies for continuous education (economic, time, and adaptive) have been revealed. The concept of continuous adult learning in the context of digitalization has been concluded. The research provides a description of the structural principles of the concept of additional education; a system of information requests of the applicant, as well as basic technologies for lifelong learning. The research indicates the lack of comprehensive research in the relevant field. The practical significance of the research results lies in the possibility of using the obtained results for a wider acquaintance of the adult population with the importance of the application of lifelong learning for professional activities and the introduction of methods for its implementation in the educational policy of the state.

기업 기밀과 고객 정보를 적절하게 보호하고 유지하기 위해, 조직은 정보보호 관리체계(ISMS), 개인정보보호 관리체계(PIMS), 비즈니스연속성 관리체계(BCMS)와 같은 경영시스템을 도입하여 운영하기 시작하였다. 본 연구는 정보보안을 고려하는 모든 조직이 정보보호 관리체계를 유지하는 것이 바람직하며 ISMS는 정보보안 문화, 실무 및 가이드라인을 고려하는 다양한 조직 안에 각기 다른 형태를 가질 수 있다는데서 출발하였다. 산업분야에 상관없이 적용 가능하고 보편적으로 널리 알려진 국제 정보보호 관리체계 ISO27001을 도입한 조직을 대상으로, 인증 심사에 따른 부적합 사례를 통해 산업별, 조직규모별, 심사유형별 정보보호 관리체계의 주요 통제 영역을 도출하려 하였다. 국내의 경우 산업분야별 인증을 유지하고 있는 곳이 많지 않아 실증 연구를 위한 자료 확보에 어려움이 있지만, 탐색적 연구 대상으로서의 의미가 있는 것으로 보인다. 분석을 통해, 대상 업체들에서 ISO27001:2013이 발표된 2013년부터 2020년까지 각 형태별로 부적합 빈도수가 가장 높았던 요구사항을 주요 통제영역으로 도출하였다. 이를 바탕으로 3개 산업분야, 조직규모, 심사유형에 따라 ISMS의 주요 통제항목에 차이가 있다는 것을 발견하였다.

In the article of instability on the peak power level, duration and repetition period of a multifrequency space-time signal, we calculated the maximum values of the errors of the parameters of the laws of spatial-phase-frequency control. Requirements for the accuracy of the location of the phase centers of the emitters in a cylindrical phased array antenna with pyramidal horns; it is advisable to calculate the radiation field using single-stage and multi-stage distribution laws. The phase centers of individual radiation sources of a cylindrical phased array antenna have been studied; they have almost no effect on the duration and period of recurrence.

Internet of things (IoT) has emerged as the most popular technique that facilitates enhancing humans' quality of life. However, most time sensitive IoT applications require quick response time. So, processing these IoT applications in cloud servers may not be effective. Therefore, fog computing has emerged as a promising solution that addresses the problem of managing large data bandwidth requirements of devices and quick response time. This technology has resulted in processing a large amount of data near the data source compared to the cloud. However, efficient management of computing resources involving balancing workload, allocating resources, provisioning resources, and scheduling tasks is one primary consideration for effective computing-based solutions, specifically for time-sensitive applications. This paper provides a comprehensive review of the source management strategies considering resource limitations, heterogeneity, unpredicted traffic in the fog computing environment. It presents recent developments in the resource management field of the fog computing environment. It also presents significant management issues such as resource allocation, resource provisioning, resource scheduling, task offloading, etc. Related studies are compared indifferent mentions to provide promising directions of future research by fellow researchers in the field.

Vehicular Ad hoc Networks (VANET's) are gaining popularity in research community with every passing year due to the key role they play in Intelligent Transportation System. Their primary objective is to provide safety, but their potential to offer a variety of user-oriented services makes them more attractive. The biggest challenge in providing all these services is the inherent characteristics of VANET itself such as highly dynamic topology due to which maintaining continuous communication among vehicles is extremely difficult. Here comes the importance of routing solutions which traditionally are designed using strict layered architecture but fail to address stringent QoS requirements. The paradigm of cross-layer design for routing has shown remarkable performance improvements. This paper aims to highlight routing challenges in VANET, limitations of single-layer solutions and presents a survey of cross-layer routing solutions that utilize the information from the MAC layer to improve routing performance in VANET.

There are many possible ways to configure database management systems (DBMSs) have challenging to manage and set.The problem increased in large-scale deployments with thousands or millions of individual DBMS that each have their setting requirements. Recent research has explored using machine learning-based (ML) agents to overcome this problem's automated tuning of DBMSs. These agents extract performance metrics and behavioral information from the DBMS and then train models with this data to select tuning actions that they predict will have the most benefit. This paper discusses two engineering approaches for integrating ML agents in a DBMS. The first is to build an external tuning controller that treats the DBMS as a black box. The second is to incorporate the ML agents natively in the DBMS's architecture.

It is essential to satisfy class-specific QoS constraints to provide broadband services for new generation networks. The present study proposes a QoS-driven multicast scheme for wireless networks in which the transmission rate and end-to-end delay are assumed to be bounded during a multiple multicast session. A distributed algorithm was used to identify a cost-efficient sub-graph between the source and destination which can satisfy QoS constraints of a multicast session. The model was then modified as to be applied for wireless networks in which satisfying interference constraints is the main challenge. A discrete power control scheme was also applied for the QoS-aware multicast model to accommodate the effect of transmission power level based on link capacity requirements. We also proposed random power allocation (RPA) and gradient power allocation (GPA) algorithms to efficient resource distribution each of which has different time complexity and optimality levels. Experimental results confirm that the proposed power allocation techniques decrease the number of unavailable links between intermediate nodes in the sub-graph and considerably increase the chance of finding an optimal solution.

오늘날 많은 기업들이 비용절감을 위해 서버 가상화 기술의 이용 및 보급을 확대함에 따라 가상화 서버에서의 사이버범 죄도 크게 증가할 것으로 예상된다. 서버 가상화 솔루션은 각 가상화 서버에 대한 가상머신 이미지를 생성하는 기능을 기본적으로 제공하기 때문에 서버 가상화 환경에서는 기존의 디지털 포렌식 수사과정의 디스크 이미지 수집과정을 생략하고 가상머신 이미지를 법적증거로 직접 활용함으로써 보다 신속하고 효율적인 수사가 가능하다. 하지만 가상화 서버의 구조적 특징으로 인해 나타날 수 있는 보안 취약성, 그리고 서버 가상화 솔루션의 신뢰성과 증거수집 절차상의 문제들로 인해 가상머신 이미지 자체만으로는 법적증거로서의 허용성을 인정받지 못한다. 본 논문에서는 가상머신 이미지가 법적증거로서 허용성을 인정받기 위해 서버 가상화 솔루션이 갖추어야 할 보안 요구사항, 디지털 포렌식 도구로서의 신뢰성 조건들을 도출하였으며, 가상머신 이미지가 증거로서의 연계보관성을 만족시키기 위해 갖추어야할 부가요소들을 제안한다. 또한 이러한 조건들을 통해 가상머신 이미지 증거가 미국 연방증거법의 법적 허용성 기준들을 만족시키는지 살펴보고, 이를 위한 관련 기관들의 구체적인 역할 및 세부 추진계획들을 제안한다.
