Professor Hyunjung Kim's research lab focuses on interdisciplinary studies at the intersection of health, urban planning, and data-driven decision making. Her work explores the physiological impacts of exercise on metabolic health, particularly through myokines like irisin, while also investigating the role of environmental factors—such as walkability—in shaping urban living and public health outcomes. Additionally, the lab examines the integration of big data and business intelligence for sustainable policy and industry development, especially in response to global challenges like the COVID-19 pandemic. The lab emphasizes evidence-based solutions that bridge biological, urban, and technological domains.

The novel myokine irisin has been reported as a therapeutic target for metabolic disease. The objective of this study is to reveal the effects of aerobic training (AT) and resistance training (RT) on circulating irisin levels and their associations with change of body composition in overweight/obese adults. Twenty eight overweight/obese adults (BMI>23 kg/m(2)) were included in this study and compared before and after 8 weeks of exercise program (60 min/day, 5 times in a week). The subjects, in b
Epstein-Barr virus (human herpesvirus-4) is very common virus that can be detected in more than 95% of the human population. Most people are asymptomatic and live their entire lives in a chronically infected state (IgG positive). However, in some populations, the Epstein-Barr virus (EBV) has been involved in the occurrence of a wide range of B-cell lymphoproliferative disorders (LPDs), including Burkitt lymphoma, classic Hodgkin's lymphoma, and immune-deficiency associated LPDs (post-transplant
Efficient decision making based on business intelligence (BI) is essential to ensure competitiveness for sustainable growth. The rapid development of information and communication technology has made collection and analysis of big data essential, resulting in a considerable increase in academic studies on big data and big data analysis (BDA). However, many of these studies are not linked to BI, as companies do not understand and utilize the concepts in an integrated way. Therefore, the purpose o
This study aims to examine the relationship between the level of walkability and housing prices in Seoul, Korea. The average transaction price per square meter for each apartment complex was set as a dependent variable and the walkability score was used as an independent variable. This study divided a total of 5986 apartment complexes into areas with high and low housing prices for analysis. Based on the strong spatial autocorrelations of housing prices, this study employed spatial regression mo
Since walkability plays an important role in active commuting, several cities are actively promoting its integration into urban and environmental planning policies. This study examined the association between walkability and active commuting in Seoul, Korea. A multilevel logistic regression model was used to examine the correlation between Walkability Score and the probability of active commuting after controlling for individual variables. The analysis used 129,044 individual samples nested with
The COVID-19 outbreak has restricted international travel, halting tourism globally. Thus, travel demand has shifted from international to domestic destinations. The prolonged travel restriction has changed travel trends and travelers’ behaviors, adversely affecting the tourism industry worldwide. This study attempted to understand and examine the changes in travel preferences, such as choice of destinations, activities, and transportation modes, following the COVID-19 outbreak. This study used
This study compared first responders' cardiopulmonary resuscitation (CPR) performance when a dispatcher provides audio instructions only and when both audio and video instructions are given. In the simulation, an automatic external defibrillator (AED) was delivered via drone in response to a cardiac arrest occurring outside a hospital setting. Participants' qualitative experiences were also explored.An exploratory sequential mixed methods design was used. AEDs were delivered to college students
A walkable environment is a crucial factor for promoting active transportation. The purpose of this study is to examine the association between neighborhood walkability and active transportation for noncommuting purposes (leisure and shopping) in Seoul, Korea. The Walkability Score is used as a measure of walkability, and a multilevel logistic regression model is employed to measure the odds of active transportation (i.e., walking and cycling; nonmotorized trips) at two levels: individual (level
Automatic floor plan analysis has gained increased attention in recent research. However, numerous studies related to this area are mainly experiments conducted with a simplified floor plan dataset with low resolution and a small housing scale due to the suitability for a data-driven model. For practical use, it is necessary to focus more on large-scale complex buildings to utilize indoor structures, such as reconstructing multi-use buildings for indoor navigation. This study aimed to build a fr
The study of environmental sustainability in the aviation industry mainly focuses on research targeting specific regions such as the United States, Europe, and China. However, for the environmental sustainability of the aviation industry, global airlines on all continents around the world must implement efficient environmental management. This study divides the world into six continents and attempts to verify environmental efficiency for airlines belonging to each continent. Using data from 2014
Since the dawn of the 21st century, Japan has switched its national industry strategy from traditional industries—manufacturing and trading—toward tourism. Regional revitalization is a particularly important issue in Japan, and by uniting regions as an integrated tourism zone, the government expects an increase in visits to tourism zones. This study quantitatively evaluates whether the regions that contain a tourism zone experience a significant increase in visitors by using a quasi-experimental
The dorsolateral medullary syndrome (Wallenberg's syndrome) is produced by infarction of a wedge of lateral medulla posterior to the inferior olivary nucleus, and is usually caused by vertebral artery occlusion. Ipsilateral axial lateropulsion as an initial symptom of vertebral artery occlusion is rare, and the responsible anatomical structure is still uncertain. Here we describe a patient presenting with ipsilateral axial lateropulsion as an initial symptom of vertebral artery occlusion.
본 연구의 목적은 병원 간호사의 직장 내 괴롭힘이 이직의도에 미치는 효과를 확인하기 위함이다. 연구대상자는 병원 근무 간호사 500명이었다. 자료 수집은 구조화된 설문지를 통해 자가보고 형식으로 2014년도 3월 1일부터 20일까지 수집하였고, 통계분석은 SPSS/PC+ ver. 18.0을 이용하여 위계적 다중 회귀분석으로 분석하였다. 연구결과, 이직의도는 직장 내 괴롭힘과 양의 상관이 있었고, 간호근무환경, 감성지능 및 직무만족과 음의 상관관계가 나타났다. 또한 직장 내 괴롭힘은 이직의도에 정적인 영향을 주었고, 간호근무환경, 감성지능 및 직무만족은 이직의도에 부적인 영향을 주었다. 감성지능은 직장 내 괴롭힘과 이직의도와의 관계에서 조절효과가 나타나지 않았지만 직무만족은 직장 내 괴롭힘과 이직의도와의 관계에서 조절효과가 있었다. 이러한 결과는 직장 내 괴롭힘, 간호근무환경, 감성지능, 직무만족이 간호사의 이직의도에 강하게 영향을 주는 요인이었다. 따라서 직장 내 괴롭힘을 예방할 수
