研究室紹介

Professor Cheol-hwan Kim's research lab focuses on aging-related health disparities, particularly the interplay between physical frailty, cognitive decline, and chronic disease progression in older adults. The lab investigates modifiable health factors such as grip strength, mobility, depression, and urinary incontinence to identify early markers of frailty and improve geriatric care. Additionally, the lab contributes to sustainable energy solutions through advanced battery modeling for electric and plug-in hybrid vehicles, emphasizing performance under real-world conditions. The integration of geriatric health and energy technology reflects a unique interdisciplinary approach to improving quality of life and societal sustainability.

김준혁, 김철환, 이순정, 김응상, Seul-Ki Kim, László Prikler

As environmentally friendly energy takes center stage, interests for Electric Vehicles/Plug in Hybrid Electric Vehicles (EVs/PHEVs) are getting increase. With this trend, there is no doubt EVs will take large portion to penetrations of total cars. Therefore, accurate EV modeling is required. Battery is one of the main components with the power system view of aspect. Hence, in this paper,reviews and discussions of some types of batteries for EV are contained by considering energy density and weig

SJR Q1Australasian Journal on Ageing

OBJECTIVE: The purpose of this study was to investigate the associations between urinary incontinence (UI) and physical frailty (PF). METHODS: The study participants (n = 404) who visited the geriatric clinic were divided into two groups according to the presence or absence of UI based on questionnaire results. We analysed the relationship between each factor associated with PF and the risk of UI according to the number of factors associated with PF. RESULTS: Urinary incontinence was associated

The association between cotinine-measured smokingintensity and sleep quality

SJR Q2Tobacco Induced DiseasesOA

Elevated urinary cotinine levels were associated with poor sleep quality in relatively young and middle-aged South Korean adults. Higher odds for poor sleep quality among cotinine-verified smokers who self-reported as never smokers also demonstrate the value of quantitative measurement of urinary cotinine. Prospective studies are warranted to clarify the cause-effect relationship between smoking and sleep quality.

Effects of Brief Smoking Cessation Education with Expiratory Carbon Monoxide Measurement on Level of Motivation to Quit Smoking
Wonyoung Choi, Cheol-Hwan Kim, Ok-Gyu Lee
SJR Q2Korean Journal of Family MedicineOA

BACKGROUND: Smoking rates among Korean adult males is still high despite multifaceted efforts to reduce it. In Korea, there have been several studies on the effectiveness of smoking cessation education for inpatients, health check-ups, and smoking cessation clinics. However, there haven't been any studies on the effectiveness of smoking cessation education conducted outside the hospital. This study investigated effectiveness of brief education on smoking cessation with an expiratory carbon monox

Smart EVs Charging Scheme for Load Leveling Considering ToU Price and Actual Datas
김준혁, 김철환

With the current global need for eco-friendly energies, the large scale use of Electric Vehicles (EVs) is predicted. However, the need to frequently charge EVs to an electrical power system involves risks such as rapid increase of demand power. Therefore, in this paper, we propose a practical smart EV charging scheme considering a Time-of-Use (ToU) price to prevent the rapid increase of demand power and provide load leveling function. For a more practical analysis, we conduct simulations based o
