4차 산업혁명의 핵심 성장 동력인 사물인터넷 (IoT) 기술은 자율 형으로 상호 소통하며 공간과 상황에 따른 데이터를 복합처리 할 수 있는 단계로 성장하였다. 이에 따라 IT 인프라 구조는 점점 복잡해지고 시스템을 안정적으로 유지하기 위한 모니터링 분야의 중요도가 높아지고 있다. 모니터링 기술은 과거에도 사용되었지만, 빠르게 변하는 ICT 기술에 대응할 수 있는 유연한 모니터링 시스템을 모색할 필요성이 있다. 본 논문은 오픈소스 기반 Prometheus 모니터링 시스템을 설계하고 테스트 하는 연구를 진행한다. IoT 디바이스를 기반으로 간단한 인프라를 구축하고 Exporter를 통해 디바이스에 대한 데이터를 수집한다. Prometheus는 데이터를 Pull 기반으로 수집한 뒤 Grafana를 사용하여 하나의 대시보드에 통합하고 데이터를 시각화함으로써 디바이스에 대한 정보를 모니터링 할 수 있다.

기존 모니터링 시스템들은 모니터링 대상에 따라 개별 시스템을 구현하였지만, 최근에서 Prometheus, Grafana와 같은 오픈소스를 활용하여 모니터링 시스템을 구현하고 있다. Prometheus와 Grafana를 활용하면 기존 모니터링 시스템 개발 방법에 비해서는 많은 부분이 편리해졌지만, 아직도 문제점이 남아 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 Prometheus와 Grafana를 지원하는 통합형 모니터링 시스템을 제안한다. 제안하는 시스템은 모니터링 대상 데이터의 수집, 저장, 시각화, 관리를 수행하는 세부 모듈로 역할을 구분하고 기존의 문제점을 해결할 수 있도록 각 모듈을 구현하였다. 제안하는 시스템은 이기종 데이터베이스에 저장된 모니터링 대상을 편리하게 관리하여 모니터링 할 수 있으며 단순한 조작을 통하여 대시보드를 생성할 수 있다.

With the advent and realization of Software Defined Network (SDN) architecture, many organizations are now shifting towards this paradigm. SDN brings more control, higher scalability, and serene elasticity. The SDN spontaneously changes the network configuration according to the dynamic network requirements inside the constrained environments. Therefore, a monitoring system that can monitor the physical and virtual entities is needed to operate this type of network technology with high efficiency and proficiency. In this manuscript, we propose a real-time monitoring system for data collection and visualization that includes the Prometheus, node exporter, and Grafana. A node exporter is configured on the physical devices to collect the physical and virtual entities resources utilization logs. A real-time Prometheus database is configured to collect and store the data from all the exporters. Furthermore, the Grafana is affixed with Prometheus to visualize the current network status and device provisioning. A monitoring system is deployed on the physical infrastructure of the KOREN topology. Data collected by the monitoring system is further pre-processed and restructured into a dataset. A monitoring system is further enhanced by including machine learning techniques applied on the formatted datasets to identify the elephant flows. Additionally, a Random Forest is trained on our generated labeled datasets, and the classification models' performance are verified using accuracy metrics.

Large language models (LLMs) such as ChatGPT have garnered considerable interest for their potential to aid non-native English-speaking researchers. These models can function as personal, round-the-clock English tutors, akin to how Prometheus in Greek mythology bestowed fire upon humans for their advancement. LLMs can be particularly helpful for non-native researchers in writing the Introduction and Discussion sections of manuscripts, where they often encounter challenges. However, using LLMs to generate text for research manuscripts entails concerns such as hallucination, plagiarism, and privacy issues; to mitigate these risks, authors should verify the accuracy of generated content, employ text similarity detectors, and avoid inputting sensitive information into their prompts. Consequently, it may be more prudent to utilize LLMs for editing and refining text rather than generating large portions of text. Journal policies concerning the use of LLMs vary, but transparency in disclosing artificial intelligence tool usage is emphasized. This paper aims to summarize how LLMs can lower the barrier to academic writing in English, enabling researchers to concentrate on domain-specific research, provided they are used responsibly and cautiously.

Electronic educational environments in the conditions of quarantine restrictions of COVID-19 have become a common phenomenon for the organization of distance educational activities. Under the conditions of Russian aggression, Ukrainian proof of their use is unique. The purpose of the article is to analyze the role of electronic educational environments in the process of training applicants for higher education in Ukraine in the realities of a large-scale war. General scientific methods (analysis, synthesis, deduction, and induction) and special pedagogical prognostic methods, modeling, and SWOT analysis methods were used. In the results, the general properties of the Internet educational platforms common in Ukraine, the peculiarities of using the Moodle and Prometheus platforms, and an approximate model of the electronic learning environment were discussed. The reasons for the popularity of Moodle among Ukrainian universities are analyzed, but vulnerable elements related to security are emphasized. It was also determined that the high cost of Prometheus software and less functionality made this learning environment less relevant. The conclusions state that the military actions drew the attention of universities in Ukraine to the formation of their own educational platforms. This is especially relevant for technical and military institutions of higher education.

본고의 목적은 <엑스 마키나>(2015)에서 프로메테우스 모티프 사용을 프로메테우스 신화, 프랑켄슈타인 모티프, 현대 SF영화의 층위에서 고찰함으로써 SF영화에서의 이 모티프의 변화 양상을 밝히는 데 있다. 첫째로, 프로메테우스 신화('살아있는 존재의 창조')의 층위에서 <엑스마키나>의 가장 큰 변화는 프로메테우스-에피메테우스-판도라-제우스의 인물 사각형이 네이든-칼렙-에이바의 삼각형으로 바뀌었다는 것인데, 이는 인간이 신을 밀어내고 창조주의 자리를 차지함으로써 과학기술의 발전이 불러올 문제를 풀고 해피엔드를 가져올 존재가 없어졌음을 의미한다. 둘째로, 프랑켄슈타인 모티프('금지된 지식에 대한 애호', '오만', '창조주에 대한 피조물의 증오')의 층위에서 이 영화는 칼렙이 소설 『프랑켄슈타인』의 로버트 월턴 선장처럼 창조주와 피조물의 이야기의 목격자로 남게 함으로써 프랑켄슈타인-괴물(네이든-에이바) 중심의 서사가 유지되도록 하지만 에이바의 '기계성'을 크게 부각시킴으로써 소설과 차별화한다. 셋째로, 현대 SF영화의 층위에서 다른 것들과는 달리 이 영화에서는 반란이 진압되지 않고 기계가 승리하여 그 능력이 인간의 그것을 넘어서는 것을 보여주는데, 이는 인간에게 귀속되지 않는 '새로운 종의 출현'을 제시하면서 인간과 기계의 새로운 관계 정립을 요구한다. <엑스 마키나>가 이처럼 다양한 층위에서 프로메테우스 모티프를 다루는 것은 하나의 모티프가 축적해온 다양한 내용을 활용하고 변형을 통해 새로운 요소를 추가함으로써 서사를 매우 풍부하게 한다는 의미를 갖는다. 본 연구의 의의는 그러한 다층적 모티프 사용과 그것을 통한 서사의 확장을 구체적인 사례를 통해 증명했다는 데 있다.

Written simultaneously with Prometheus Unbound, Shelley's "Julian & Maddalo" is a masterwork of dramatic poiesis, of doubling embedded in its couplets, dialogic debate on human nature and contrasted symbolic emblems. The emblems mirror each other and are themselves sites of generative paradox: the "heaven illumined" but "dreary tower" of the Maniac and the glorious sunsets on the "ever-shifting sand" of the Lido, a wasteland that is a place of self discovery but also of "abandonment" and barren mingling figured, inter alia, in its "amphibious weeds," a trope of the poem's personae. This essay also explores the poem's dramatic structure and various rhetorical devices, beginning with the Preface, a threshold of complex identity disguise that Shelley uses for veiled self-presentation, as in "Alastor," mirroring and literary references replete with nuanced ironies. I focus mainly on the complex figures of liminality Shelley uses to develop his own thoughts (as well as his ongoing debates with Byron) about man's potential for growth in thought, insight and empathy, in political reform and interpersonal and individual healing. Advancing Shelley's most optimistic ideas, Julian, escorted by Maddalo observes the Maniac, -- a living ruin whose pained eloquence reveals the link of eros to poiesis and the limits of the latter's ability to 'transform a world.' The Maniac is the core of muse-work (remembering, thinking and song) and Shelley presents him as its emblem. He also is prefigured in and reflects the quintessentially liminal Lido with its "barren embrace" of sea and land. Yet it is less the Maniac's feeling that his grief is "charactered in vain…on this unfeeling leaf" than Julian's rationales for leaving the site of pain that point to Shelley's final comment on poetry's transformative limits. As the primary haploids of the drama's meiosis re-combine and two of them, Maddalo and the maniac fall away, an analogy I briefly develop and embedded in the erotic dynamics of poiesis, Shelley suggests, as he did at the beginning of his poetic lyricism in "Alastor" and at its end in "the Triumph of Life"that images mislead and delude; that "the deep truth is imageless" and redemption is not in but beyond figuration.
