Natural killer (NK) cell-based immunotherapy has been considered a promising cancer treatment strategy with low side effects for early tumors and metastasis. However, the therapeutic efficacy is generally in established solid tumors. Ex vivo activation of NK cells exogenous cytokines often essential but ineffective to generate high doses functional treatment. Image-guided local delivery also suggested therapy. there lack noninvasive tools monitoring cells. Herein, magnetic nanocomplexes are...
Biological dosimetry is an essential analytic method to estimate the absorbed radiation dose in human body by measuring changes biomolecules after exposure. Joint response a network mass-casualty incidents one way overcome limitations of biological dosimetry, sharing workload among laboratories. This study aimed investigate current performance, collaborative activities and technical advances Korea biodosimetry (K-BioDos), suggest future directions toward successful joint response.
The dicentric chromosome assay is a gold standard method to estimate radiation exposure by calculating the ratio of chromosomes existing in cells. objective this study was propose an automatic discrimination based on deep convolutional neural networks using patient data. From 45 patients with exposure, conventional Giemsa-stained images 116,258 normal and 2800 were confirmed. ImageNet used pre-train VGG19, which modified fine-tuned. proposed VGG19 demonstrated performance, true positive rate...
Fine ordered stripe patterns are developed through the evaporative self-assembly of a PMMA-toluene solution and O2 plasma for applications to optical waveguide devices. The were formed by repeating "stick-slip" motion contact line in restricted geometry. High-quality patterned lines obtained removing residue pattern's sidewall using an asher.
A simple route to intriguing patterns for optical waveguides was demonstrated by controlled evaporative self-assembly (CESA) of confined microfluid. Silica ridge were fabricated applying wet and dry etching based on stripe formed CESA. The mode the resulting confirmed exposing them 1064 nm transmission light.
Highly ordered reduced graphene oxide (RG-O) micro-patterns were crafted by an efficient method capitalizing on the self-assembled polymer template. Central to this strategy is fabricate template over a large area via controlled evaporative self-assembly (CESA), and treat templated glass substrate with O2 plasma render favorable interaction between RG-O platelets substrate, thereby yielding well-defined microscopic patterns scale.
목적: 본 연구는 4차 산업혁명 시대 스마트 융합의 첨단 기술을 언어치료 현장에 적용해보고자 한다. 이를 실현하기 위해 동적 움직임을 표현할 수 있는 증강현실 기반 프로그램의 매체 개발을 통하여 자폐성장애 아동의 의문사 습득 중재에 대한 효과를 알아보는데 그 목적이 있다. 방법: 연구의 대상아동은 10~16세 아동 3명으로 주 2~3회기, 총 18주(33회기) 기초선, 중재, 일반화, 유지 단계로 중재를 실시하였다. 매 회기 개별적으로 연구자와 아동이 1:1로 진행하였으며, 중재는 기반의 프로그램을 태블릿 PC를 이용하여 그림카드 인식이 가능한 어플리케이션 구현으로 68개의 장면 제시를 통한 145개의 문항으로 습득의 평가는 매회기 12개의 문항에 대하여 ‘누가 3문항, 무엇(뭐) 6문항, 어디 3문항’으로 구성하여 정반응률로 살펴보았다. 결과: 대상아동 모두 기초선 단계와 비교하여 중재 단계에서는 회기가 진행될 때마다 정반응률이 증가하였으며, 일반화 단계에서 또한 향상된...
A surface sensor rendering an extended detection range was proposed and demonstrated, taking advantage of a Y-branch structure. The sensing reference waveguides, comprising the structure, were overlaid with TiO 2 films different thicknesses; thus, they show unequal sensitivities. phase change experienced by two waveguides in situ monitored through birefringence analyzer. interference number for waveguide derived from response waveguide. implemented evaluated varying concentration glucose...

Foot drop can occur as a manifestation of number pathological and clinical conditions is fairly common disability encountered in electrodiagnostic clinics. This report describes two cases atraumatic foot drop. Both were electrophysiologically diagnosed peroneal neuropathy around the fibular head. Radiographic surgical findings confirmed intraneural ganglion cyst nerve resection was performed. Although radiographic compatible with lesion nerve, precise analysis electrophysiologic could...
High sensitivity biosensors were investigated in an attempt to improve the surface morphology of polymer waveguides using chemical mechanical polishing technology. The waveguides, based on fluorinated polyethers, fabricated by a combination photo-lithography and reactive ion etching, then their surfaces polished under variety processing conditions. root means square roughness (RMS) waveguide decreased from 12.8 3.7 nm with increasing time after dry-etching process. detection evanescent field...
