A novel series of N0-(1-(aryl)ethylidene)-2-(5,5-dioxido-3-phenylbenzo[e]pyrazolo[4,3-c][1,2]thiazin-4(1H)-yl)acetohydrazides was synthesized. The synthesiswas carried out by thermal method as well as ultrasonicbath to reduce reaction time and to enhance product yields. The synthesized compounds were characterized by spectroscopictechniques like NMR, infrared and EIMS. Thestructure of compound 5w was elucidated by X-ray crystallography. The titled compounds were evaluated for antihumanimmunodeficiency virus type 1 (anti-HIV-1) andcytotoxic activities. Biological studies indicated thatamongst these compounds, 5a, b, j, h and i showed theactivity with median effective concentration (EC50) valuesless than 20 lM. Compound 5i exhibited the most potentanti-HIV-1 activity (EC50 = 3.2 lM) while 5h showedanti-HIV-1 activity (EC50 = 3.8 lM) with no toxicity at allin primary human lymphocytes, CEM and VERO cells.

정보 중심 네트워킹(ICN)과 그 결실인 명명된 데이터 네트워킹(NDN)은 호스트 중심 주소 기반 통신 아키텍처에서 컨텐츠 중심 이름 기반 통신 아키텍처로 패러다임의 전환을 제안하고 있다. NDN은 풀 기반 통신 모델을 따르고, 중간 노드의 포워딩 상태를 유지함으로써 소비자(최종 사용자) 모빌리티를 기본적으로 지원한다. 반면에 생산자(콘텐츠 생성자) 이동성은 NDN의 원래 아키텍처 설계에서 초기에 지원되지 않았었다. 따라서, 모바일 생산자 노드에서 발생하는 성능 저하 문제를 효율적으로 해결하기 위해, 최근 몇 년 동안 다수의 생산자 이동성 계획이 제안되어 왔다. 본 논문에서는 문헌에서 제안된 기존의 연구 노력(생산자 이동성의 맥락에서)에 대한 간략한 조사를 제공했다. 본 논문은 이동성 제도를 1) 유선 네트워크에서의 생산자 이동성과 2) 무선 네트워크에서의 생산자 이동성으로 분류하였다. 무선 네트워크에 대한 생산자 이동 체계는 VANETs(Vehicular AdHoc Networks)의 맥락에서 개략적으로 설명된다. 또한 NDN의 효율적인 생산자 이동성과 관련된 향후 연구 방향과 과제를 조명했다. Information-centric networking (ICN) and its fruition, the named data networking (NDN) is a paradigm shift from host-centric address-based communication architecture to the content-centric name-based communication architecture. NDN follows a pull-based communication model and natively supports the consumer (end-user) mobility by maintaining the forwarding states on Intermediate nodes. The producer (content-generator) mobility, on the other hand, was not initially supported in the original architectural design of NDN. Therefore, to efficiently address the degradation issues incurred by mobile producer nodes, a plethora of producer mobility schemes have been proposed over the recent few years. In this paper, we provided a brief survey on the existing research efforts-in the context of producer mobility, that have been proposed in the literature. This paper classified the mobility schemes into two main categories 1) producer mobility in wired networks and 2) producer mobility in wireless networks. The producer mobility schemes for wireless networks are outlined in the context of Vehicular AdHoc Networks (VANETS). Moreover, we also shed light on the future research directions and challenges associated with the efficient producer mobility in NDN.

This paper discusses the experiences of international students in Korea and their involvement in various educational activities. The paper begins with a brief introduction of the students and their journey to Korea, followed by an exploration of the value of religion and its role in their life as Muslim international students. The paper then delves into the events in which the students participated, including a cross-cultural activity, a walk in the KNU, a food stall at the KNU fair, a visit to the mosque, a Daehyeon-dong movie day, an international cooking program, and an Apsan observatory hiking event. The paper highlights the cultural exchange and interactions that took place during these events, as well as the significance of such activities in promoting cross-cultural understanding and appreciation. The paper also acknowledges the efforts of the organizers and the role played by the university in facilitating these activities. Overall, the paper emphasizes the importance of such events in promoting cultural diversity and understanding in today’s globalized world.
