Nuclear factor kappaB (NF-kappaB) is associated with the transcriptional activation of genes encoding chemokines, adhesion molecules, cytokines, and anti-apoptotic proteins, which are key components in immune responses viral infection. Many viruses modulate NF-kappaB through numerous gene products to allow productive infections escape. Here we report that herpes simplex virus-1 infected cell protein 27 (HSV-1 ICP27), an immediate early HSV-1, represses activity binding inhibitor...
In this study, we developed a fiber-optic humidity sensor (FOHS) system for the monitoring and detection of coolant leakage in nuclear power plants. The FOHS includes an FOHS, spectrometer, halogen white-light source, Y-coupler. is composed humidity-sensing material, metal tube, multi-mode plastic optical fiber, subminiature version A (SMA) connector. material synthesized from mixture polyvinylidene fluoride (PVDF) dimethyl sulfoxide (DMSO) hydroxyethyl cellulose (HEC) distilled water. We...
This study suggests an optimization method for the life cycle cost (LCC) in economic feasibility analysis when applying energy saving techniques early design stage of a building. Literature and previous studies were reviewed to select appropriate LCC techniques. The simulation (Energy Plus) computational program (MATLAB) linked provide automated process. From results, it is suggested that this process could outline model with which possible minimize LCC. To aid understanding model, case on...
Ipsilateral breast tumor recurrence (IBTR) remains a concern despite standard treatments. Advances in early detection have shifted surgical paradigms towards less invasive approaches. While repeat sentinel lymph node biopsy (rSLNB) emerges as viable option according to the 2023 National Comprehensive Cancer Network (NCCN) guidelines, its efficacy uncertain. This study aimed assess lymphatic drainage patterns IBTR and evaluate feasibility of rSLNB, along with analyzing oncologic outcomes.
In order to provide appropriate practical training for quality nursing care, it is necessary evaluate performance competencies in terms of clinical careers. Using convenience sampling, this cross-sectional study aimed identify the and education needs operating room nurses by evaluating nurses’ The participants were 182 working rooms four general hospitals Seoul, Korea. Data came from self-report questionnaires regarding needs. results showed that participants’ differed significantly across...
Objectives The purpose of this study is to analyze secondary school teacher’s subjective perceptions online classes through the Q methodology and categorize results. Methods In study, data were collected literature review individual surveys. From data, 138 Q-populations extracted using in-depth interview 31 Q-samples established an expert process. Subsequently, a P-sample 30 teachers from Chungnam region was organized, Q-sorting conducted. Results analyzed PQ Method program, resulting in...
본 연구의 목적은 코로나19 사태 이후 시작된 온라인 수업에 대한 교사의 경험을 확인하고 앞으로의 교육 방향을 모색하기 위한 것이다. 이를 위해 서울 소재 초등학교 교사 6명을 대상으로, 2020년 7월에서 8월 초에 걸쳐 포커스 그룹 인터뷰(Focus Group Interview: FGI)를 실시하였다. 인터뷰 후 자료를 질적 내용분석(qualitative content analysis)으로 조직화(organizing)하였다. 분석 결과, 첫째 환경적 경험은 지침에 따른 학교 운영의 변화, 구성원에 의사결정, 동료교사와 협업구조 형성으로 나타났다. 둘째, 심리적 감염병에 두려움, 변화에 당황스러움, 부담감, 콘텐츠 제작 관련 기대감, 뿌듯함과 부러움으로 드러났다. 셋째, 실천적 프로그램 사용 방법 습득, 수업 제작, 집단지성의 발휘, 열린 구조로의 변화였다. 넷째, 학생 학생의 학력 저하 파악, 역량·성실성의 판별, 참여 동기 및 주의력 확인이었다. 다섯째, 학부모 공교육의...
Based on the results of previous trials, de-escalation axillary surgery after neoadjuvant chemotherapy (NAC) has increased in patients with lymph node (ALN) metastasis at presentation. This study aimed to review trends by time period and molecular subtype ALN metastasis.We analyzed rates sentinel biopsy (SLNB) dissection (ALND) based subtype. The was divided into 3 subperiods determine rate type over (period 1, from 2009 2012; 2, 2013 2016; 3, 2017 July 2019).From 2019, 2,525 breast cancer...
본 연구는 코로나 19로 인한 사상 최초로 벌어진 교육과정 전 과목 온라인 수업에 관한 연구로 온라인수업으로 진행함에 따른 학과별 문제점과 한계점을 설명하고 대안점을 모색한다.<BR> 고등학생 대상으로 FGI와 설문조사로 학습효과 및 적절성에 논의를 하여, 수업의 다학제적인 방안을 모색하고자 시작되었다.<BR> 해외 학교 설립과 공개수업(MOOC)에 이슈를 반영하여 K-MOOC, 즉 수강인원이 제한 없이(Massive), 수강 가능한(Open,) 웹 기반(Online) 강좌(Course)를 2015년부터 2017년까지 130억 예산을 들어 사업에 착수했다. 그러나 수업을 이용하는 학생과 이수율은 저조했으며, KOCW(Korea OpenCoursWare, 대학 공개강의 공동 활용 서비스)사업 강좌와 중복 사용되는 점 등을 예산과 효율성에 관해 문제가 대두되었다.<BR> 인해 교과과정을 수업으로 진행에 유형과 특징이 있을 것으로 보고, 적용했을 때에 공통되는 살펴보았다. 공통적인...
Purpose: Immunohistochemical (IHC) evaluation is important for the management of breast cancer. Cold ischemic time (CIT) may result in inaccurate IHC results. The aim this study was to investigate effect CIT on results invasive ductal carcinoma (IDC). Methods: We retrospectively reviewed records 316 patients diagnosed with IDC from February 2013 June at a single hospital Korea. clinicopathological characteristics and positivity estrogen receptor (ER), progesterone (PR), Ki-67, human...
In this study, we fabricated a dual type fiber-optic radiation sensor (DFORS) system using spectroscopic technique to measure alpha and beta particles simultaneously separately. The DFORS is composed of sensing probe, plastic optical fiber (POF), photomultiplier tube (PMT)-amplifier system, multichannel analyzer (MCA). As probes, ZnS(Ag) film CaF2(Eu) crystal were used for spectroscopy. And, measured the energy spectra proposed discriminate species radioisotopes emitting or particle. From...
본 연구는 세계 각국의 데세코 프로젝트 결과를 근거하여 교육정책 및 과정 그리고 혁신적인 교육(학습)역량이라는 범위를 연구하는 과정에서 시작되었다.<BR> 학습역량을 특정 영역에 대한 복합적인 지식, 인지적, 실용적, 기술, 태도, 정서, 가치, 동기 등 다방면을 이용하여 성공적인 해결능력을 키우기 위한 융합적인 모형의 틀로 보고 있다.<BR> 다시 말해, 다학제적인 성격을 가진 학습역량이 중요한 만큼 개발된 자료와 학생들 간의 실질적인 차이와 인식에 요소를 파악할 필요가 있다고 본다.<BR> 학습역량의 자료에서 융합 부분과 그 외 의미를 구분해 보았다.<BR> 연구자료를 살펴본 결과, 연구자들의 영역으로 학습동기 학습심리로 보았고, 학습환경에 따는 구분했다.<BR> 이 부분에 학생들의 의견 인식을 파악하기 위해 전공이 다른 대학생 대상으로 소그룹을 구성하여 2회에 걸쳐 인터뷰를 진행했다.<BR> 질문내용은 문헌 정보 토대로 내용축약과 질문유형으로 1차 인터뷰에서는 총...
