Background: The COVID-19 pandemic’s transition to an endemic phase emphasizes the importance of vaccination. Despite initial strong immunogenicity, waning vaccine-induced immunity requires further investigation. Therefore, this study evaluated immunogenicity BNT162b2 vaccine in adolescents, focusing on spike-specific and neutralizing antibody kinetics following primary booster vaccinations as well impact breakthrough infections. Methods: This observational included 157 adolescents 12–17...
Concerns about the effectiveness of current vaccines against rapidly spreading severe acute respiratory syndrome-coronavirus-2 omicron (B.1.1.529) variant are increasing. This study aimed to assess neutralizing antibody activity wild-type (BetaCoV/Korea/KCDC03/2020), delta, and variants after full primary booster vaccinations with BNT162b2. A plaque reduction neutralization test was employed determine 50% dilution (ND
Tixagevimab/cilgavimab is a monoclonal antibody used to prevent coronavirus disease 2019 among immunocompromised hosts and maintained neutralizing activity against early omicron variants. Omicron BN.1 became dominant circulating strain in Korea 2023, but its susceptibility tixagevimab/cilgavimab unclear. We conducted plaque reduction neutralization test (PRNT) prospective cohort (14 patients 30 specimens). PRNT was for one- three-months after administration the average ND50 of each point...
Vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been acknowledged as an effective mean of preventing infection and hospitalization. However, the emergence highly transmissible SARS-CoV-2 variants concern (VOCs) led to substantial increase in infections among children adolescents. Vaccine-induced immunity longevity have not well defined this population. Therefore, we aimed analyze humoral cellular immune responses ancestral after two shots BNT162b2 vaccine...
Network security systems such as firewall and intrusion prevention system (IPS) have packet classification rule to allow or protect the network traffic. In addition, they are forced provide multi-gigabit speed in order deploy current Internet backbone which requires gigabit Ethernet (GbE), 10 GbE, OC-192, etc. support high-performance system, a ternary content addressable memory, i.e., TCAM accelerates flow identification with rules. The TCAM, however, matches first among multiple matched...
본 연구는 학문 목적 한국어 학습자들이 읽기 수업의 과제 수행 상황에서 다중 텍스트를 활용하는 양상을 분석하였다. 텍스트 활용은 이해하기 위해 관련성이 있는 여러 개의 다른 찾아 내용을 통합하는 활동을 의미한다. 학습자들마다 이해 수준이 같지 않고 방식이 다르다는 점에서 그 구체적인 살펴보는 것은 교육 현장에 시사하는 바가 클 것이다. 이러한 목적으로 연구에서는 활용 목적, 사용 언어, 출처, 그리고 유형이라는 4가지 기준을 바탕으로 검색한 총 63개의 학습자들은 주제 이해를 빈도가 가장 높았고, 학습자들의 모국어로 된 찾은 경우도 25%로 비교적 높게 나타났다. 또한, 사적 텍스트의 비율이 68%였으며, 양식에 있어 단일양식 83%로 상당히 분석 결과를 토대로 향후 현장에서 활용의 효율성과 신뢰성을 높일 수 교수 방안을 제안하였다.
Introduction Although the safety and effectiveness of COVID-19 vaccination during pregnancy have been proven, there is still little data explaining neonatal outcomes maternal pre-pregnancy vaccination. Methods Here, we investigated impact SARS-CoV-2 infection on maternal-neonate immune response in a cohort study involving 141 pregnant individuals, defined importance timing for its effectiveness. Results discussion Our indicate that vertically transferred hybrid immunity provides...
Nipah virus (NiV), of the Paramyxoviridae family, causes highly fatal infections in humans and is associated with severe neurological respiratory diseases. Currently, no commercial vaccine available for human use. Here, eight structure-based mammalian-expressed recombinant proteins harboring NiV surface proteins, fusion glycoprotein (F), major attachment (G) were produced. Specifically, prefusion NiV-F and/or NiV-G glycoproteins expressed monomeric, multimeric (trimeric F tetra G), or...
Chikungunya fever is a mosquito-borne infectious disease caused by the chikungunya virus (CHIKV). Recently, CHIKV has spread rapidly worldwide, raising global concerns. However, there only one approved vaccine available to prevent infection; therefore, different platform vaccines development public health priority. The genome encodes four non-structural polyproteins (nsP1-4) and structural polyprotein (capsid, envelope 3, 2, 6 K, 1). Previous studies have shown that N-linked glycans in viral...
Background: Controversy remains regarding the safety of COVID-19 vaccination during pregnancy. Here, we investigated impact and SARS-CoV-2 infection on maternal-neonate immune response in a cohort study involving pregnant individuals, defined importance maternal timing for its effectiveness.Methods: We divided 141 participants into groups according to time SARS CoV-2 infection. Maternal blood samples were collected pregnancy at delivery. Newborn from cord taken after Blood sera used PRNT...
A novel approach to describe the relation, in terms of probability, between gain obtained by multiplexing traffics packet network and link capacity for guaranteeing required quality is proposed. traffic-flow defined as on-off stream described with probability distribution lengths. With statistical flow description, loads on a after aggregating traffic flows can be predicted design based supporting becomes possible. To have model small number data, an interpolation method suggested. find...
We introduce the architecture of a multiprotocol label switching (MPLS) edge router (LER) system based on ACE2000 ATM system. implemented MPLS LER by adding service controller and interface module (MIM) with 2.5 Gbit/s throughput to also describe implementation MIM that can support ships-in-the-night mode such as Internet in designed have high-performance IP function well processing functions. It consists physical layer part, forwarding engine VC merging switch part. The most important part...
As a next generation service, immersive media is the most attractive one, which indispensable for supporting human tele-presence and virtual lab. The service requires high standards on interactive response delay synchronization among comfortable communication in users' perspective. To measure customer's experiences from network provider side, we propose new of quality experience (QoE), distortion ratio datum (DRS), by calculating how much original statistical property distorted at receiver...
In this paper, we describe the necessity of VC merging in an edge label switched router (LSR) for scalability, one important merits multi-protocol switching (MPLS). We introduce design a high-speed IP forwarding engine with virtual connection (VC) merging. This largely consists segmentation and reassembly (SAR) processing part, CAM-based look-up VC-merging physical line interface part. It provides some desirable characteristics that are described paper. also compare MPLS systems centralized...
The immunogenicity of a heterologous vaccination regimen consisting ChAdOx1 nCoV-19 (a chimpanzee adenovirus-vectored vaccine) followed by mRNA-1273 lipid-nanoparticle-encapsulated mRNA-based against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), specifically the omicron variant (B.1.1.529), is poorly studied. aim this study was to evaluate neutralizing antibody activity and prime-boost wild-type (BetaCoV/Korea/KCDC03/2020), alpha, beta, gamma, delta, variants SARS-CoV-2 in...
이 연구의 목적은 학문 목적 한국어 학습자들의 읽기 능력 향상을 위해 필수적인 글의 형식적 특징과 구조 파악을 위한 활동이 실제 교재에 어느 정도 구현되고 있는가를 분석하는 것이다. 이를 텍스트의 특징 교육 내용으로 포함하고 있는 교재 6권을 검토한 결과 학습자들에게 실제적으로 도움이 될 수 충분한 명시적으로 제시되고 있지 않음을 확인할 있었다. 특히 특징을 다루고 교재의 수는 여전히 부족하며 장르나 유형, 전략에 초점을 둔 교재임에도 및 구조의 학습을 설명과 연습이 나와 않았다. 향후 개발되는 교재에서는 파악 단원의 주제와 유기적으로 연계되어 과정 속에 제시됨으로써 내용 지식 활성화 탐색을 지원할 활동으로 구성되어야 할
The Ethernet technoglogy rapidly gains importance as becoming a dominant solution for converged transport network. Recently added features such QoS handling and OAM functions in the framework of ITU-T NGN provides means performance improvement to meet carrier-class network requirements. In addition, integration with newly developed T-MPLS by offers potential replace current SDH/SONET-based infrasctructure.
