研究室紹介
Professor Ji Hyun Kim's research lab specializes in regenerative medicine and bioengineering, focusing on the development of advanced tissue-engineered constructs for clinical applications. The lab pioneers 3D bioprinting technologies to create functional, implantable skeletal muscle tissues that mimic native physiology, with an emphasis on enhancing tissue integration and neuromuscular functionality. Additionally, the lab investigates metabolic regulation and neurovascular mechanisms in disease models, including obesity and ischemic stroke, using preclinical and molecular approaches. These interdisciplinary efforts aim to bridge tissue engineering with translational medicine for regenerative therapies.

15PURPOSE: Previous neuroimaging studies provide growing evidence that patients with juvenile myoclonic epilepsy (JME) have both structural and functional abnormalities of the thalamus and frontal lobe gray matter. However, limited data are available regarding the issue of white matter (WM) involvement, making the microstructural WM changes in JME largely unknown. In the present study we investigated changes of WM integrity in patients with JME, and their relationships with cognitive functions and
This study examined the effects of maternal parenting behaviors, children's social information processing, daily hassles, and emotional regulation on school-age children's aggressive behaviors using Structural Equation Modeling(SEM) analysis. Subjects were 589 children in 4, 5, 6th grade and their mothers from three elementary schools in Seoul, Korea. Data were analyzed with descriptive statistics and SEM analysis by SPSS 12.0 and AMOS 4.0. The SEM shows differences between overtly aggressive an
GCC loss in the NTG group was more localized compared with diffuse GCC loss in the POAG group. Perimacular GCC parameters could be a good alternative or supplement to peripapillary RNFL measurements for diagnosis and research in patients with NTG.
PURPOSE: The purpose of this study was to investigate the prevalence and characteristics of glaucoma in the population of the rural Korean town, Sangju. METHODS: Residents of Sangju aged greater than 50 years old were included in this study. Participants completed an interview examining their medical and ophthalmic history Information was collected on the participants' uncorrected and best corrected vision scores, slit lamp examination results, angle width measurements using the Van Herick techn
본 연구는 코로나19 상황에서 개인이 겪은 어려움과 변화들이 가족관계 만족도에 어떠한 영향을 미쳤는지 2020년 9월에 수집된 서베이 자료를 활용하여 분석하고자 한다. 코로나19로 인해 경제, 돌봄, 관계 단절 모든 면에서 여성이 남성보다 더 많은 피해를 경험한 것으로 나타났다. 돌봄공백을 경험한 부부의 23%만이 일가정양립제도를 사용하였으며, 여성의 제도 사용 비율이 남성보다 높았다. 코로나19 확산 이후 가족들은 더 많은 시간을 함께 보내게 되었고 이는 가족관계 만족도에 긍정적 영향을 미쳤지만, 남성의 가사분담 여부에 따라 그 영향력이 조절되는 것으로 나타났다. 일가정양립제도 사용은 긍정적 영향을, 가구소득 감소, 돌봄부담 증가, 본인 가사 증가 등은 부정적 영향을 미쳤다. 본 연구는 재택근무가 활성화될 가능성이 높은 현실에서 사회의 기초단위인 가족이 평안과 안정의 공간이 되기 위해서는 젠더평등이 중요하며, 이를 증진시킬 정책이 중요함을 제시하였다.
Purpose: To compare corneal sensitivity and recovery of corneal innervation between temporal and superior clear corneal incisions in cataract surgery. Methods: We compared the change in corneal sensitivity in patients with cataract who had received phacoemulsification using either temporal clear corneal incisions (group 1) or superior clear corneal incisions (group 2). The changes were measured at 1 week, 1 month, and 3 months after surgery using the Cochet-Bonnet esthesiometer. For a different
PURPOSE: Overactive bladder (OAB) is a manifestation of urgency, regardless of urge incontinence, due to involuntary bladder contraction during the storage period. There is a close association between constipation and OAB, but constipation cannot be readily diagnosed. The aims of this study were to evaluate the prevalence of constipation in OAB and the consequent therapeutic effects according to the diagnostic criteria for constipation. METHODS: We collected clinical data from 40 children (mean
본 연구는 공직자들을 연구대상으로 하여 인사관리에 대한 공무원의 공정성 인식이 공공봉사동기에 미치는 영향 을 탐색하고, 이러한 영향 관계에서 업무자율성과 상사피드백이 가지는 조절효과를 분석하였다. 특히 인사관리에 대한 공정성을 분배공정성, 절차공정성, 상호작용 공정성으로 나누어 분석한 결과, 인사관리에 대한 절차공정성 인 식이 공무원의 공공봉사동기에 통계적으로 유의미한 정(+)의 영향을 끼치는 것을 확인하였다. 또한 업무자율성과 상사피드백의 조절효과를 검증한 결과, 업무자율성이 높아질 때 분배공정성과 상호작용 공정성이 공공봉사동기에 미치는 영향력을 증가시켰고, 상사 피드백이 높을 때 절차공정성과 상호작용 공정성이 공공봉사동기에 미치는 영향 력을 증가시킨다는 것을 볼 수 있었다. 본 연구결과는 공공봉사동기의 선행요인으로 조직 차원에서의 공정성 가치 를 다루고, 공공봉사동기에 영향을 미치는 업무자율성과 상사피드백의 긍정적 역할을 조명하는 정책적 함의를 제공 했다는데 연구의 의의가 있다.
In this study, we examined whether melatonin promotes apoptotic cell death via p53 in prostate LNCaP cells. Melatonin treatment significantly curtailed the growth of LNCaP cells in a dose- and time-dependent manner. Melatonin treatment (0 to 3 mM) induced the fragmentation of poly(ADP- ribose) polymerase (PARP) and activation of caspase-3, caspase-8, and caspase-9. Moreover, melatonin markedly activated Bax expression and decreased Bcl-2 expression in dose increments. To investigate p53 and p21
In Brief Purpose: To estimate the prevalence of asteroid hyalosis (AH) in Seoul, Korea, and to identify risk factors for the condition. Methods: A cross-sectional study with review of fundus photographs of subjects who received a health check-up between January 2006 and December 2006 at the Yonsei Medical Examination Center yielded 9,050 available cases (aged 40 years or older). AH was diagnosed retrospectively by the presence of cream-white spherical bodies within the vitreous, as seen in the f
Unilateral BoNT-A injection appears to be an effective esthetic treatment for patients with muscle-induced facial asymmetry.
Sialyllactoses (SL) are an abundant component of human milk. There have been many studies on the biological effects of SL in humans. SL can be produced using an economical method of enzyme synthesis. Although the European Food Safety Authority has published the human safety and appropriate intake dose of 6'-SL sodium salt as a novel food, it has suggested that the appropriate dose for particular medical purposes be judged on a case-by-case basis. Also, as revealed in the same report, there are n
