Plaque Patterned Cutaneous Candidiasis on the Lower Legs: A Case Report
성재영,임지원,김창용,조영아,이양원,최용범,유다애 대한의진균학회 2023 대한의진균학회지 Vol.28 No.4
Diabetes mellitus (DM) is a metabolic disorder that causes chronic hyperglycemia, leading to immune dysfunction and increased vulnerability to infections. As a result, patients with DM are more susceptible to fungal infections, including Candida species, due of their weakened immune systems. Cutaneous candidiasis is a fungal infection that appears as a red plaque with peripheral satellite papules and pustules around the periphery. Patients with chronic mucocutaneous candidiasis may have erythematous plaques and thickened skin thickening with an overlying scale, which can mimic plaque psoriasis. Therefore, fungal infections should be considered when assessing chronic refractory psoriasiform lesions that are difficult to treat, especially in patients with DM. This report describes a case of cutaneous candidiasis in both lower legs, which was initially misdiagnosed as psoriasis.
SONOS NAND 플래시 메모리 소자에서의 lateral charge migration에 의한 소자 안정성 연구
성재영,정준교,이가원 한국반도체디스플레이기술학회 2019 반도체디스플레이기술학회지 Vol.18 No.4
As the NAND flash memory goes to 3D vertical Silicon-Oxide-Nitride-Oxide-Silicon (SONOS) structure, the lateral charge migration can be critical in the reliability performance. Even more, with miniaturization of flash memory cell device, just a little movement of trapped charge can cause reliability problems. In this paper, we propose a method of predicting the trapped charge profile in the retention mode. Charge diffusivity in the charge trapping layer (Si3N4) was extracted experimentally, and the effect on the trapped charge profile was demonstrated by the simulation and experiment.
Extraction of Effective Charge Diffusivity in the Charge Trapping Layer of SONOS Flash Memory
성재영,정준교,남기령,이가원 한국전기전자재료학회 2021 Transactions on Electrical and Electronic Material Vol.22 No.4
In this study, the effective electron diffusivity in a silicon nitride is extracted experimentally explaining the lateral charge migration in Silicon-Oxide-Nitride-Oxide-Silicon memory device whose charge trapping layer is formed continuously along the memory string. The diffusivities were compared in two types of silicon nitride by changing the deposition conditions. The enhanced charge loss is found to be related with the Si–O–N bonding which shows 5.28% versus 23.72%, analyzed by X-ray photoelectron spectroscopy and larger shallow trap density by the thermal activated electron retention model. The analysis results show that less oxygen bonds are more favorable in data retention properties suppressing the lateral charge migration and this can be represented by lower diff usivity about 3.8 × 10 –11 –5.1 × 10 –10 cm 2 /s.
Molecular Co-evolution of Gonadotropin-releasing Hormones and Their Receptors
성재영,권혁방 한국통합생물학회 2007 Animal cells and systems Vol.11 No.2
Gonadotropin-releasing hormone (GnRH),synthesized in the hypothalamus, plays a pivotal role in theregulation of vertebrate reproduction. Since molecularisoforms of GnRH and their receptors (GnRHR) have beenisolated in a broad range of vertebrate species, GnRH andmolecular co-evolution of a peptide ligand-receptor pair.Vertebrate species possess multiple forms of GnRH, whichhave been created through evolutionary mechanisms suchas gene/chromosome duplication, gene deletion andmodification. Similar to GnRHs, GnRH receptors (GnRHR)have also been diversified evolutionarily. Comparativeligand-receptor interaction studies for non-mammalian andmammalian GnRHRs combined with mutational mappingstudies of GnRHRs have aided the identification of domainsor motifs responsible for ligand binding and receptorGnRHR co-evolution, particularly the structure-functionrelationship regarding ligand selectivity and signal transductionof mammalian and non-mammalian GnRHRs.
