Oral monitoring plays an essential role in preventing and diagnosing systemic diseases through saliva in the mouth. Dietary monitoring is also crucial to reduce the likelihood of chronic diseases such as hypertension and diabetes by analyzing food types, amounts and diet patterns. Therefore, the oral cavity and dietary monitoring are vital for accurate personalized healthcare management that can improve healthcare. To perform continuous oral cavity and dietary monitoring in real-time, a wearable

Abstract Mobile health (mHealth) with continuous real-time monitoring is leading the era of digital medical convergence. Wearable devices and smartphones optimized as personalized health management platforms enable disease prediction, prevention, diagnosis, and even treatment. Ubiquitous and accessible medical services offered through mHealth strengthen universal health coverage to facilitate service use without discrimination. This viewpoint investigates the latest trends in mHealth technology,

Body shape and curvature are vital criteria for judging health. However, few studies exist on the curvature of the body. We present a skin-interactive electronic sticker that digitally decodes the epidermis deformation in a hybrid cartridge format (disposable bandages and non-disposable kits). The device consists of two functional modes: (1) as a thin electronic sticker of 76 μm thickness and a node pitch of 7.45 mm for the measurement of body curvature in static mode, and (2) as a wrist bandage

Dietary monitoring is vital in healthcare because knowing food mass and intake (FMI) plays an essential role in revitalizing a person’s health and physical condition. In this study, we report the development of a highly sensitive ring-type biosensor for the detection of FMI for dietary monitoring. To identify lightweight food on a spoon, we enhance the sensing system’s sensitivity with three components: (1) a first-class lever mechanism, (2) a dual pad sensor, and (3) a force focusing structure

Obstructive sleep apnea syndrome disrupts sleep, destroys the homeostasis of biological systems such as metabolism and the immune system, and reduces learning ability and memory. The existing polysomnography used to measure sleep disorders is executed in an unfamiliar environment, which may result in sleep patterns that are different from usual, reducing accuracy. This study reports a machine learning-based personalized twistable patch system that can simply measure obstructive sleep apnea syndr

The unique oriental dietary culture, ‘chopsticks,’ has been widely distributed and used since oriental culinary arts and delights were introduced. However, few studies were there on sensing the gripping force of chopsticks while cooking and eating. Here, we report a stretchable finger-perimetric sensor that can help analyze the gripping force of food mass intake by chopsticks. Briefly, the device consists of a force sensing element to analyze finger-gripping forces and a flexible gap for the mea

목적: 본 연구 전국의 분만을 취급하는 산부인과 병의원을 대상으로 HBV 산모로부터 출생한 신생아의 백신 투여실태를 조사하는 것이다. 연구 방법: 2001년도 연간 분만 건수 100건 이상인 병의원 848곳을 대상으로 2003년 1월 15일부터 2003년 2월 15일까지 우편을 통한 설문조사를 시행하여 HBsAg 양성 산모의 신생아에게 면역글로부린 및 간염백신의 투여와 모유수유 현황을 조사하였다. 설문을 보낸 848개의 병의원 중에서 최종 회수된 설문지는 341건으로 40.2%가 회수되었다. 결과: HBsAg 양성 임신부에게 출생한 신생아에게 출생 후 면역글로부린 및 1차 간염 백신투여 시기에 대해 분포를 조사해 적기인 ‘12시간 이내에 투여하고 있는 경우가 90% 이상’이라고 보고한 병의원이 전체의 91.9%이며 분만병의원에서 현재 사용 중인 신생아 간염백신은 0-1-6방식을 가장 많이 사용하는 것으로 나타났다. 임신부의 HBsAg/HBsAb의 결과를 모르는 경우 신생아의 면역글로

Display-driven optical stimuli underpin a major class of clinically validated digital therapeutics (DTx) now expanding from neuropsychiatric disorders to chronic diseases. The display's optical characteristics-spectral power distribution, luminance, contrast, and temporal modulation-therefore define the delivered dose of these software-based interventions. In this context, blue-rich emission in the 450-480 nm band, particularly with evening exposure, can suppress melatonin via melanopsin-mediate

Objective: The purposes of this study were to investigate the types and the incidences of chromosomal abnormalities, and to provide an explanation for the genetic causations of recurrent spontaneous abortions in Korean population. Methods: Cytogenetic studies were carried out in 535 couples with at least two spontaneous first trimester abortions from January 1981 to December 2003. For karyotype analysis, we used modified Moorhead method by Giemsa staining and Giemsa-Trypsin-Giemsa banding Result

Flexible Throat Patch In article number 2400059, Wonki Hong proposes a sensory transformation approach for machine learning-based dietary analysis and voice recognition. Based on a flexible patch that converts the sense of tactile into hearing and taste, it analyzes the vibrations and movements of the laryngeal muscles to understand pronunciation and peristalsis to determine the type of food consumed.

Abstract The throat is an organ that includes the larynx, esophagus, and bronchi. Vocalization or deglutition triggers micro‐movements of muscles around the throat. In this study, based on machine learning using a flexible patch, pronunciation is identified by analyzing the vibration and movement of the laryngeal muscles, and the type of food consumed is determined through peristalsis analysis. Previously, voices are recognized through cochlea hair cells, and the type of food intake is identifie

자궁근종은 자궁에 생기는 양성 종양 중 가장 흔한 종양으로 40세 이상의 여성 40-50%에서 자궁근종을 가지고 있다. 자궁근종의 병인은 아직 알려져 있지 않지만 몇몇 연구들에서 각각의 자궁근종은 자궁근층의 평활근 중 하나의 종양 세포에서 기원하는 것으로 보고되었다. 또한 자궁근종은 드물게 자궁 바깥에서 자랄 수 있고, 골반 정맥 내로 자라기도 하며, 폐까지 전이된 예가 보고되기도 하였다. 이러한 전이성 평활근종이 90여년 전에 처음으로 알려진 이래 현재까지 이의 발생 기전이나 치료에 대한 확립된 이론은 없는 상태이다. 본 저자들은 폐 전이를 동반한 양성 전이성 평활근종 1예를 경험하였기에 간단한 문헌 고찰과 함께 이를 보고하는 바이다.

목적: 본 연구의 목적은 악성 난소암에서 quantitative real-time RT PCR과 Western blot analysis를 이용하여 HLA-G의 mRNA와 단백질의 발현 정도를 측정한 후, 이의 발현 정도에 따라 HLA-G의 발현의 의미와 난소암의 다른 예후 인자들과의 상관 관계를 조사하는 것이다. 연구 방법: 1997년부터 2005년 현재까지 난소암으로 진단받은 환자 중 43명의 난소 조직을 실험 군으로, 정상 난소 조직 5예를 대조 군으로 하여 전향적인 연구를 시행하였다. 악성 난소암 환자는 기초 검사를 시행한 후 병기 결정을 위한 개복술을 시행하였으며 수술 후 보조 항암화학요법을 시행하였다. Quantitative real time RT PCR과 Western blot analysis를 이용하여 HLA-G의 mRNA와 단백질의 발현을 측정하였다. 결과: 난소암 조직에서의 HLA-G의 mRNA 발현의 2-△△Ct의 median값은 1.21 (0-9)였고, 대조 군
