Professor Ji Hun Kim's research lab specializes in neurodegenerative disease mechanisms, with a focus on Lewy body dementia (LBD) and alpha-synuclein pathology. The lab investigates how ultra-low-intensity ultrasound (ULIUS) modulates astrocyte reactivity through the TRPA1 ion channel, aiming to develop non-invasive therapeutic strategies. Using primary astrocyte cultures, neuron-glia co-cultures, and transgenic mouse models, the lab explores the role of glial activation in neuroinflammation and disease progression. Their work highlights the potential of ultrasound-based neuromodulation as a precision tool for targeting glial and neuronal dysfunction in synucleinopathies.

Polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), especially the 2,3,7,8-substituted congeners, are extremely toxic, persistent, and recalcitrant to remediation. Dechlorination of PCDD/Fs by zerovalent iron (ZVI) is thermodynamically feasible, but useful rates of reaction have not been previously reported. Here we show that ZVI (both micro- and nanosized ZVI, without palladization) dechlorinates PCDD congeners with four or more chlorines in aqueous systems, but the reaction is too slow to
A novel spectroscopic method is proposed for the measurement of electron density and temperature in atmospheric pressure dielectric barrier discharges using nitrogen gas. Simplified collisional-radiative models for the electronic and the vibrational states yield two separate continuity equations as a function of the electron density and the temperature with the coefficients expressed in terms of rotational temperature, vibrational temperature, and emission intensity ratio between the first posit
AIP patients seem to have a higher risk of UC compared with the general population. The increased IgG4-positive cellular infiltration in the colonic tissue suggests that UC may be an extrapancreatic manifestation of AIP.
Abstract This study provides an in‐depth examination of the relationship between environmental, social, and governance (ESG) performance and the idiosyncratic volatility of Korean companies. In line with the risk‐mitigation view, the study finds that strong ESG performance is associated with a reduction in a firm's idiosyncratic volatility. The impact of ESG performance on reducing firm volatility was particularly evident during the COVID‐19 pandemic, highlighting the role of ESG performance in
The purpose of this study was to investigate the combined effect of mechanical and chemical treatments on the shear bond strength (SBS) of metal orthodontic brackets on zirconia restoration. The zirconia specimens were randomly divided into 12 groups (<i>n</i> = 10) according to three factors: AL (Al<sub>2</sub>O<sub>3</sub>) and CO (CoJet™) by sandblasting material; SIL (silane), ZPP (Zirconia Prime Plus), and SBU (Single Bond Universal) by primer; and N (not thermocycled) and T (thermocycled).
본 연구의 목적은 간호대학생의 비판적 사고성향, 공감능력, 간호전문직관, 셀프리더십이 문제해결능력에 미치는 융복합적 영향을 확인하는 것이다. 연구대상자는 편의표집방법을 사용하여 서울, 충남, 울산에 소재한 4년제 대학교의 간호학과에 재학 중인 학생224명으로 2013년 3월 6일부터 4월 20일까지 자료수집이 이루어졌다. 자료는 SPSS/WIN 21.0을 이용하여 분석하였다. 본 연구결과 연구대상자의 문제해결능력은 비판적 사고성향, 공감능력, 간호전문직관 및 셀프리더십과 정적 상관관계를 보였으며, 학점과 대인관계가 좋은 경우가 그렇지 않은 경우보다 문제해결능력이 높았다. 위계적 회귀분석을 실시한 결과, 간호대학생의 문제해결능력에 영향을 미치는 요인은 비판적 사고성향, 공감능력, 간호전문직관, 셀프리더십, 학점, 실습만족도이었으며, 그 중 가장 큰 영향력을 가진 변수는 비판적 사고성향이었다. 본 연구의 결과는 간호대학생의 문제해결능력을 향상시키기 위해서는 비판적 사고성향과 공감능력,
This is the first report of a Korean family that carries a PDGFRB mutation potentially responsible for supernumerary premolars. Our results demonstrate the power of next-generation sequencing in rapidly determining the genetic aetiology of numerical tooth abnormalities.
The effect of Y addition on the glass forming ability (GFA) of in Fe70TM(TM=Mn, Mo, Ni)13B17 alloys have been examined in the present study. Substitution of 3-10 at% Fe with Y improves the GFA. Fe70−xMn13B17Yx (x = 5) and Fe70−xMo13B17Yx (x = 3) alloys exhibit high Trg (=Tg/T1)(>0.55) and γ (=Tx/[T1 + Tg]) (>0.37) values enabling fabrication of 1 mm diameter bulk metallic glass. The GFA improves when addition of Y decreases the melting temperature, and, at the same time, increases the crystalliz
Chinese middle-school history textbooks emphasize that China's engagement in Korean War was justified, and blames the U.S.A. for the outbreak of the war. Chinese textbooks state that Korean War was triggered by South Korea's aggression on North Korea according to American plans. In addition, in an effort to emphasize China's win of Korean War over the U.S.A, the textbooks do not intentionally highlight the existence of South Korea or South Korean troops. Regarding the result of the war, they als
