In the context of the massive spread of coronavirus disease 2019 (COVID-19), the development of a COVID-19 vaccine is urgently needed. The Pfizer-BioNTech COVID-19 vaccine has been widely applied across global populations. Herein, we report a case of acute interstitial nephritis with acute kidney injury in a young healthy subject after administration of the COVID-19 vaccine. A 20-year-old man was admitted with abdominal discomfort and nausea. He had received the Pfizer-BioNTech COVID-19 vaccine 6 days before. At 9 days after vaccination, his kidney function was decreased, with serum creatinine levels of 1.8 mg/dL. Even with supportive care with hydration, his kidney function worsened, and he underwent a kidney biopsy. The pathology findings revealed diffuse interstitial infiltration of inflammatory cells, predominantly comprising lymphocytes, with preservation of the glomerulus. No abnormal findings were noted by immunofluorescence or electron microscopy. Based on a diagnosis of drug-related acute interstitial nephritis, we treated the patient with high-dose prednisolone. After administration of prednisolone, kidney function slowly improved. A close linkage between COVID-19 vaccination and acute interstitial nephritis should be considered in the clinic, despite the low incidence.

본 연구를 통해 개발된 청소년 식생활·영양 실천 평가 항목은 총 22개의 문항으로 청소년들이 개인의 전반적인 식사의 질 및 식행동, 식환경을 영역별로 평가 가능하며, 향후 청소년의 식생활 개선을 위한 평가 도구로 활용될 수 있다. 한국인을 위한 식생활 지침을 기반으로 청소년의 다양한 식생활, 식문화와 관련된 선행연구, 국민건강영양조사자료, 국가 정책 및 지침에 대한 검토와 전문가 대상 타당도 평가를 진행하여 58개의 수도권단위 예비 조사용 체크 리스트 평가항목을 우선 선정하였다. 수도권단위 조사는 중·고등학생 403명을 대상으로 진행되었고, 조사 자료의 탐색적 요인분석 결과 식단의 질 평가항목을 식품섭취, 식행동, 식생활 환경 세 영역으로 분류하였다. 식사섭취실태와의 상관관계 분석을 통해 수렴타당도를 분석하고 최종 모형으로 총 22개의 평가항목이 도출되었다. 최종적으로 청소년 식단의 질 평가도구는 식품섭취 영역 10개 항목 (채소류, 황색채소, 생과일, 계란 및 육류, 콩과 견과류, 우유·유제품, 다양한 식품군, 가당음료, 가공육류, 튀김류), 식행동 영역 4개 항목 (유산소, 체중유지, 끼니섭취 횟수와 규칙적인 식사), 식생활 환경 영역 8개 항목 (유통기한, 덜어먹기, 로컬푸드, 친환경식품, 가정 내 신선한 과일채소, 유제품의 비치와 부모님의 식사준비 여부 및 건강한 간식 섭취의 격려)으로 구성되었다. 본 연구의 청소년 식생활·영양 실천 평가 항목은 22개의 간단한 문항으로 청소년들이 개인의 전반적인 식사의 질 및 식행동, 식환경을 영역별로 점수 평가하는데 용이하다는 점에서 청소년의 식생활 개선을 위한 도구의 활용이 기대된다. Purpose: A comprehensive evaluation item was developed to assess adolescent dietary habits and nutritional practices, considering food intake, eating behaviors, and food culture, such as social support and food environment. Methods: The 59 candidate items of the evaluation checklist were obtained based on the results of the eighth Korea National Health and Nutrition Examination Survey data, Korea Dietary Reference Intakes, dietary guidelines for adolescents, Youth Risk Behavior Survey data, national nutrition policies and dietary guidelines, and literature reviews. Four hundred and three middle and high school students residing in metropolitan areas participated in a survey using the 58-item checklist, which was selected through expert evaluation and content validity ratio analysis. The construct validity of the assessment tool for the quality of adolescent diets was assessed by exploratory factor analyses to determine if the checklist items were organized properly and whether the responses to each item were distributed adequately. Results: The Bartlett sphericity test was significant for each area (p <0.001), and the eigen values were greater than one. The Kaiser-Meyer-Olkin and cumulative proportions by areas were food intake (0.765 and 56.8%, respectively), eating behaviors (0.544 and 64.8%, respectively), and food environment (0.699 and 62.4%, respectively). Twenty-two checklists were determined for the final evaluation items for the adolescents’ dietary habits and nutritional practices and were categorized into three distinct factors: food intake (10 items), eating behaviors (4 items), and food environment (8 items). Conclusion: The evaluation items for adolescent dietary habits and nutritional practices is a useful checklist for easily and quickly assessing the dietary qualities and reflecting Korean adolescents and their food environmental factors related to a sustainable diet.

Correlation method for high speed size determination of nanoparticles using ICP-MS

Jimin Shim,Y. H. Park,H. B. Lim(임흥빈) 한국분석과학회 2021 학술대회논문집 Vol.2021 No.11

ICP-MS has a lot of potential to detect nanoparticles owing to its outstanding capability for reliable quantification, size distribution and particle concentration. Recently developed single particle ICP-MS (sp-ICP-MS) has been demonstrated remarkable performance to various fields with limited applications. The limitations are clear in the viewpoints of analytical figures-of-merits, i.e., lack of reliable information such as reproducible size distribution, particularly, for the sizes near quantification limit and low particle concentration, and requirement of many parameters to be experimentally determined or assumed. And those eventually make practical application difficult. In this concept, the size estimation model was recently developed in our lab and showed excellent demonstration for the nanoparticles of NIST standard Au, and SiO₂. The model established the correlation of the integrated area of the peak to the cubic of particle radius through the data treatment based on Window Peak Selection and Gauss Fitting. Since the model greatly relies on the trueness of the correlation curve, sample preparation, peak selection, and the fittings are carefully controlled throughout the data handling process. Finally, iron oxide (Fe₂O₃) nanoparticle was studied for further proof and practical application to semiconductor process. In summary, the developed method showed reliable performance for high speed analysis of nanoparticles which enable to do on-line monitoring of nanoparticles in the various manufacturing processes.

Jimin Cheon,Youngcheol Chae,Dongsoo Kim,Seunghyun Lim,Inhee Lee,Hyoung-Ki Lee,Dong Jo Kim,Gunhee Han IEEE 2009 IEEE transactions on electron devices Vol.56 No.11

<P>Light-section (LS)-based range finders are commonly used for obstacle recognition in home service robots and autonomous vehicles. This paper proposes a smart CMOS image sensor for LS-based range finding. The proposed sensor can detect the laser light, even under very strong ambient-illumination levels by using a multiple-capture frame-correlated double sampling (F-CDS), which is realized with an inverter-based switched-capacitor F-CDS accumulator. The proposed sensor also includes on-chip winner-take-all circuits that significantly reduce the software and hardware complexity of interpolation for the subpixel resolution. The prototype chip was fabricated using a 0.35-mum CMOS process. The measurement results show that the proposed sensor can detect a laser line with an intensity that is 56.5 dB lower than that of the ambient illumination, providing a spatial resolution of plusmn0.16 pixels.</P>

Jimin Yoon,Shan Lim 국제문화기술진흥원 2021 International Journal of Advanced Culture Technolo Vol.9 No.4

Since the late 20th century, various projects in the public domain where local communities and art organizations collaborate have been attempted in miscellaneous ways. In terms of anticipating an active attitude of the community, socially engaged project focuses on proactively changing everyday life and environment of people. An art collective, Assemble who won the Turner Prize in 2015 for one of their projects named Granby Four Streets (2013) has been admitted as an exemplary of this phenomenon, and it appears frequently in discussions about community-led projects. We investigate Granby Four Streets, as well as the documentation formed by the perspective of third parties based on the surveillance and criticism aspects. It asserts that the limitation of socially engaged projects that are kept ephemerally and easily forgotten could be overcome with the concept of documentation and its practice.

도시화와 기후변화는 기저유출이 하천유량에 미치는 계절적 변동성을 야기시킨다. 이러한 기저유출의 변동성은 수생태의 영향을 줄 뿐만 아니라 불안정한 수자원 관리를 초래 할 수 있다. 또한 토지이용변화는 하천유량과 기저유출에 영향을 주며, 이로 인해 다른 수문순환 요소들에게 미치게 된다. 이에 본 연구에서는 갑천(602km²) 유역을 대상으로 SWAT(Soil and Water Tool)모형을 이용하여 기후변화 및 토지이용변화의 따른 직접유출과 기저유출 상관관계를 분석하고자 하였다. 모의 시 1995년과 2009년 사이의 토지이용변화를 이용 하였으며, 기후변화의 시간적 경향은 1990-2017년의 기간으로 설정하여 SWAT 모형에 다양한 시나리오를 적용하여 분석하였다. BFlow program을 통해 alpha factor를 산정한 후, 적용하여 SWAT 모형 보정 결과의 유량 예측의 정확성을 향상시켰다. 이를 통해 기저유출을 산정하는데 있어 중요한 특성인 감수부 부분도 SWAT 모형 보정시 반영 하였으며, BFlow program을 이용하여 기저유출을 산정하였다. 갑천유역의 토지이용변화 분석결과는 1995년부터 2009년 동안 유역면적이 약 29.53 km² 가 농업지역에서 도시화로 되었다. 이러한 도시화는 갑천 유역 유량과 기저유출 분포도 변화의 영향을 주는 것으로 나타났다. 특히, 기저유출 측면에서는 토지이용 변화의 따른 영향보다 기후변화의 대한 영향이 수문학적으로 영향을 더 크게 미치는 것으로 나타났다. 본 연구를 결과를 통해 수문환경조건 변화에 따른 수자원을 정량적으로 파악 할 수 있으며, 수자원 관리계획 정보를 제공할 수 있을 것으로 기대된다.
