Obesity increases the risks of diabetes, hypertension, and cardiovascular diseases, ultimately contributing to mortality. Korean Society for Study (KSSO) was established improve management obesity through research education; that end, Committee Clinical Practice Guidelines KSSO reviews systemic evidence using expert panels develop clinical guidelines. The practice guidelines were revised in 2018 National Health Insurance Service checkup data from 2006 2015. Following these guidelines, we...
We investigated the relationships of adiponectin/leptin (A/L) ratio with cardiovascular risk factors, insulin resistance index, and metabolic syndrome (MS) in apparently healthy Korean male adults.Sixty-eight subjects were enrolled among participants an annual health check-up program (mean age, 55.1 years). Percent body fat (%) was measured using a bioelectric impedance analyzer. Serum leptin level via radioimmunoassay, adiponectin enzyme-linked immunosorbent assay. Homeostasis model...
Renal medullary carcinoma (RMC) is a rare and deadly kidney cancer in patients of African descent with sickle cell trait. We have developed faithful patient-derived RMC models using whole-genome sequencing, we identified loss-of-function intronic fusion events one SMARCB1 allele concurrent loss the other allele. Biochemical functional characterization these revealed that requires for survival. Through integration RNAi CRISPR-Cas9 genetic screens small-molecule screen, found...
Abstract Background Wound biofilm infections impact ∼2% of the United States and at-risk individuals often have underlying morbidities such as diabetes. Antibiotics topical approaches like debridement or silver dressings had limited success, underscoring a need for strategies that efficiently target pathogens in wound beds. Methods We developed hydrogen peroxide (H2O2) generating electrochemical bandage (e-bandage) composed carbon fabric electrodes separated by cotton with an Ag/AgCl...
Deep reinforcement learning (DRL) as a routing problem solver has shown promising results in recent studies. However, an inherent gap exists between computationally driven DRL and optimization-based heuristics. While algorithm for certain is able to solve several similar instances, traditional optimization algorithms focus on optimizing solutions one specific instance. In this paper, we propose approach, AlphaRouter, which solves problems while bridging the optimization. Fitting problems,...
ABSTRACT Intraluminal infection of central venous catheters, used for long‐term treatment, can result in line‐associated bloodstream (CLABSI). These infections be challenging to prevent and treat due formation biofilms within catheter lumens, which shield bacteria from the human immune response conventional antimicrobial therapies. Preventing bacterial colonization hubs is a strategy CLABSI. To address this, we developed nonantibiotic, animal‐ready electrochemical hub (e‐catheter hub),...
This paper aimed to evaluate the applicability of adiabatic humidification in heating, ventilation, and air conditioning (HVAC) systems semiconductor cleanrooms. Accurate temperature humidity control are essential cleanrooms high energy consumption steam is commonly used. Therefore, we propose an system employing a pressurized water atomizer reduce consumption. The annual three different HVAC were analyzed humidification. studied cases as follows: (1) CASE 1: make-up unit (MAU) with...
Using only a simple tube furnace, we demonstrate the synthesis of patterned graphene directly on designed substrate without need for an external carbon source. Carbon atoms are absorbed onto Ni evaporator sources as impurities, and incorporated into catalyst layers during deposition. Heat treatment conditions were optimized so that diffused out along grain boundaries to form nanocrystals at catalyst-substrate interfaces. Graphene patterns obtained under catalysts, which restricted formation...
We propose a novel photonic application as well an optical tool to verify the crystallinity of interface-grown graphene demonstrating passive mode-locked lasers. The interface growth process enables formation multi-layered at substrate and catalyst, therefore directly onto targeted without transfer process. synthesized is characterized using Raman spectroscopy x-ray photoelectron before ultrashort pulse confirm validity for high-speed applications graphene. resultant pulses have repetition...
Acute postprandial hyperglycemia is an important affector for atherosclerosis in subjects with glucose intolerance. We analyzed the relationship of brachial-ankle pulse wave velocity (baPWV) fasting and post-challenge plasma levels according to different time points during oral tolerance test (OGTT).In 663 hyperglycemia, 75 g OGTT were performed confirm tolerant status, fasting, 30-minute 120-minute measured. Anthropometric measurements done, lipid profiles baPWV measured all between 30-...
African swine fever (ASF), a viral disease caused by the virus (ASFV), is associated with high mortality rates in domestic pigs and wild boars. ASF has been spreading since its discovery boars Korea October 2019. Genomic analyses have provided insights into genetic diversity of ASFV isolated from various regions, enabling better understanding origin transmission patterns. We conducted genome analysis to evaluate mutations among during 2019-2022. compared genomes strains Korean publicly...
최근 영상 편집 기술의 발달과 더불어 시청자의 이해를 돕기 위해 인위적으로 자막을 삽입하는 경우가 늘고 있다. 삽입된 자막은 해당 장면의 내용이나 편집자의 의도를 잘 표현하고 있기 때문에 비디오 정보 검색(video information retrieval)이나 색인(video indexing)과 같은 응용에 유용하다. 기존의 자막 영역 추출 방법은 에지(edge), 색상(color), 텍스처(texture) 정보와 하위 계층(low-level) 특징을 기반으로 하기 다양한 필체나 밝기 대비를 가진 자막이 동시에 나타나거나 복잡한 배경에 포함된 영역의 경우 검출하지 못한다. 이에 본 논문은 방법과는 전혀 다른 천이 기반의 새로운 내 검출 기법을 제안하고자 한다. 먼저, 글자 주변은 시청자에게 영상으로부터의 높이 감을 주기 글자와 색으로 표현된다는 관찰 결과를 바탕으로 지도를 생성한다. 생성된 이용하여 후보 영역을 추출하고 상태 밀도 개념을 중에서 추출한다. 제안하는 알고리즘은...
PLC 시스템은 자체 모듈에 의한 부분적 확장성을 지원하고 있지만, 확장을 위한 비용이 크고, 센서 및 기타 제어기들과의 언어 호환성 또한 문제가 되고 있다. 본 논문에서는 빠르게 변화하는 기술에 대처하기 위해 텍사스 인스트루먼트 사의 DSP(디지털 시그널 프로세서)를 이용하여 PLC를 대체 보조할 수 있는 시스템을 제안한다. 이 기존 PLC의 기능을 통합적으로 구현하며, 범용으로 쓰이는 에 비해 속도가 빠르고, 약 50% 이상의 비용 절감이 가능하다. 또한, 모듈 형태의 24V의 범용디지털 I/O핀을 구성함으로써 선택적으로 입력과 출력의 용이하게 하였다. 일반적 산업장비의 제어를 널리 사용되고 모드버스 통신을 RS-485 인터페이스를 기반으로 DSP에서 구현함으로써, 장비 간 다대다 할 있도록
ABSTRACT Electrochemical bandages (e-bandages) can be applied to biofilm-infected wounds generate reactive oxygen species, such as hypochlorous acid (HOCl) or hydrogen peroxide (H 2 O ). The e-bandage-generated HOCl H kills biofilms in vitro and infected on mice. HOCl-generating e-bandage is more active against , although this distinction less apparent vivo . -generating e-bandage, than the associated with improved healing of wounds. A strategy which are generated alternately—for dual...
Abstract Chronic wound infections can be difficult to treat and may lead impaired healing worsened patient outcomes. Novel treatment strategies are needed. This study evaluated effects of intermittently produced H 2 O HOCl, generated via an electrochemical bandage (e-bandage), against methicillin-resistant Staphylococcus aureus biofilms in agar membrane biofilm model. By changing the working electrode potential, e-bandage either HOCl (1.5 V Ag/AgCl ) or (−0.6 ). The degree biocidal activity...
