研究室紹介
Professor Yxk12's research lab specializes in cardiovascular and geriatric health, focusing on patient-reported outcomes, self-management in chronic diseases, and physiological stress responses. The lab investigates health-related quality of life, cardiac self-efficacy, and perceived health status among elderly and cardiac patients, with an emphasis on psychosocial and behavioral factors influencing health outcomes. Key research directions include the impact of chronic conditions like atrial fibrillation and coronary artery disease on daily functioning and psychological well-being, as well as biomarkers of stress such as salivary alpha-amylase and catecholamines.

15INTRODUCTION: Atrial fibrillation is the most common sustained cardiac rhythm disturbance encountered in clinical practice. Despite its high prevalence and the associated high number of hospital admissions, few studies document the actual impact of atrial fibrillation on the patient. PURPOSE: The purpose of this study was to describe the health-related quality of life (HRQOL) and to examine the impact of seriousness of illness on HRQOL in patients newly diagnosed with atrial fibrillation. METHOD
This study aimed to identify the associated factors of the perceived health status of the elderly in Korea and to provide basic data for developing nursing interventions for the elderly’s health management. Methods: This study used a descriptive correlational research design. The subjects of this study were 335 elderly people over 60 yr living in an urban city. Data were collected through personal interviews using questionnaires from September 2006 to March 2007. Empirical indicators of perceive
The aim of the study was to examine the relationships among salivary alpha-amylase, plasma catecholamines, blood pressure, and heart rate during psychological stress. This study used a pretest-post-test experimental design with a control group, using repeated measures. A total of 33 participants was divided into the experimental group (n = 16) that underwent a college academic final test as the psychological stress and the control group (n = 17) that did not undergo the test. The levels of saliv
AIMS AND OBJECTIVES: To investigate cardiac self-efficacy and its predictors among patients with coronary artery diseases. BACKGROUND: Patients with coronary artery diseases must perform the health behaviour to prevent recurrent cardiac events. It has been already well known that self-efficacy is a vital factor in both initiating and maintaining health behaviours. DESIGN: Descriptive correlational and cross-sectional survey design. METHODS: Subjects were interviewed using structured study questi

PURPOSE: To investigate the effect of cardiac knowledge and cardiac self-efficacy on health behaviors after controlling for influences from associating factors of health behaviors in patients with coronary artery diseases (CADs). METHODS: A descriptive correlational and cross-sectional design was used. Subjects with CADs were recruited from outpatient clinics of three academic medical centers. The cardiac knowledge, cardiac self-efficacy, and health behaviors were measured by Coronary Heart Dise
Nurses are the largest group of healthcare workers in the world, and during the COVID-19 pandemic, nurses have been recognized worldwide as frontline warriors working hard to stem suffering, infection rates and deaths. Korean nurses experienced the effects of the pandemic earlier than in most other countries, and the work of our nurses has been recognized as a successful model in responding COVID-19. In this paper, we share the experiences of Korean nurses, including their experiences of workloa
The behavioral and psychological symptoms of dementia (BPSD), which appear in all dementia patients, demand sizable commitments of time and effort from nurses. This study aims to identify issues related to the workloads of nurses who provide care for dementia patients via qualitative meta-synthesis. Eleven articles were selected using a systematic review flowchart, which were then evaluated for their quality using the Critical Appraisal Skills Program checklist. Collected data were analyzed usin
AIM: This study explored nurses' experiences of communicating with patients with aphasia. DESIGN: A naturalistic paradigm approach was adopted to describe the phenomenon of interest. METHODS: Participants were neurological nurses employed in various neurological departments and recruited using purposive sampling. Group interviews were conducted for 1 hr and 30 min using semi-structured open-ended questions. The Consolidated Criteria for Reporting Qualitative Research checklist was followed. RESU
This cross-sectional survey study aimed to determine the effects of uncertainty on depression through the appraisal within the "uncertainty in illness" model. In 81 subjects with atrial fibrillation, individuals with greater symptom severity perceived more uncertainty. Uncertainty was appraised as a danger rather than an opportunity. While the appraisal of opportunity had a negative relationship with depression, the appraisal of danger was positively associated with depression. The indirect effe
OBJECTIVES: The aim of the study was to examine the relationships between uncertainty and its antecedents, including education, social support and symptom frequency in Korean patients with atrial fibrillation. BACKGROUND: The antecedents of uncertainty were theoretically identified from Mishel's theory of uncertainty in illness. There is a need to examine empirically whether theoretically driven antecedents of uncertainty work in a way that the theory proposed. DESIGN: Descriptive correlational
Based on the secondary data analysis, this study aimed to identify quality of life and factors that affect quality of life among Korean elderly with mild cognitive impairment. Demographic characteristics, physical factors, and psychosocial factors as well as quality of life of the elderly with mild cognitive impairment were comprehensively measured. The research subjects consisted of 348 home-resident elderly and their quality of life scores were relatively high at 29.86. Their quality of life v
