최훈성,민대환,이한진 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.8

Technological advancements have created the fourth industrial revolution, accelerating the digital age. This transformation has led to the replacement of human labor with digital power, and the decreasing population and aging society have made efficiency more crucial. Additionally, the COVID-19 pandemic has made remote environments a new-norm, ultimately increasing the need for automation and unmanned operations. In this study, we aim to explore the technical characteristics of KIOSKs, the most representative Self-Service Technology (SST) in a remote environment. We examined the technical features of ATM and hospital KIOSK, which are most commonly used, based on the 28 items of the Persuasive Systems Design (PSD). We have been conducted a survey with 304 respondents, respectively, based on the extracted 11 items. The analysis shows that for hospital KIOSK, men recognize the credibility item of the PSD better than women, and the 50s and above demographic recognizes the technical features better than the under 50s. For ATM, the 50s and above demographic recognizes the technical features better than the under 50s demographic in the reduction and tunneling items of the PSD. Based on these results, future technical and policy implications related to the design and operation of public KIOSKs are proposed.

최훈성,김진택,이홍규,Wook-Ha Park,Youngmi Kim Pak,이성우 대한내분비학회 2021 Endocrinology and metabolism Vol.36 No.6

Background: Mitochondrial dysfunction is strongly associated with several kidney diseases. However, no studies have evaluated the potential renal hazards of serum mitochondria-inhibiting substance (MIS) and aryl hydrocarbon receptor ligand (AhRL) levels. Methods: We used serum level of MIS and AhRL and clinical renal outcomes from 1,511 participants of a prospective communitybased cohort in Ansung. MIS was evaluated based on intracellular adenosine triphosphate (MIS-ATP) or reactive oxygen species (MIS-ROS) generation measured using cell-based assays. Results: During a mean 6.9-year follow-up, 84 participants (5.6%) developed a rapid decline in kidney function. In the lowest quartile group of MIS-ATP, patients were older and had metabolically deleterious parameters. In multivariate logistic regression analysis, higher MIS-ATP was associated with decreased odds for rapid decline: the odds ratio (OR) of 1% increase was 0.977 (95% confidence interval [CI], 0.957 to 0.998; P=0.031), while higher MIS-ROS was marginally associated with increased odds for rapid decline (OR, 1.014; 95% CI, 0.999 to 1.028; P=0.055). However, serum AhRL was not associated with the rapid decline in kidney function. In subgroup analysis, the renal hazard of MIS was particularly evident in people with hypertension and low baseline kidney function. Conclusion: Serum MIS was independently associated with a rapid decline in kidney function, while serum AhRL was not. The clinical implication of renal hazard on serum MIS requires further evaluation in future studies.

최훈성,이향아,김상욱,조은희 대한내분비학회 2018 Endocrinology and metabolism Vol.33 No.2

Background: Despite the beneficial effect of fibroblast growth factor 21 (FGF21) on metabolic disease, there are concerns about adverse effects on bone metabolism, supported by animal studies. However, a recent human study showed the positive association between serum FGF21 level and bone mineral density (BMD) in healthy premenopausal women. We undertook this study to examine the association between FGF21 level and BMD in healthy postmenopausal Korean women who are susceptible to osteoporosis. Methods: We used data of 115 participants from a cohort of healthy postmenopausal women (>50 years old) to examine the association between serum FGF21 level and BMD. The clinical characteristics were obtained from the participants, and blood testing and serum FGF21 testing were undertaken. BMD of the lumbar spine, femoral neck and total hip area, and bone markers were used in the analyses. Results: The mean age of the participants was 60.2±7.2 years. Serum FGF21 levels showed negative correlation with BMD and T-scores in all three areas, but there were no statistically significant differences. Multivariate analyses with adjustment for age and body mass index also did not show significant association between serum FGF21 level and BMD. In addition, serum FGF21 level also showed no correlation with osteocalcin and C-telopeptide levels. Conclusion: In our study, serum FGF21 level showed no significant correlation with BMD and T-scores.

Background: Dry sauna treatments improve the quality of life for chronic pain, congestive heart failure, and type 2 diabetes patients. This study aimed to determine whether dry sauna therapy improved the quality of life of obese people. Methods: A total of 38 consecutive participants aged over 20 years with a body mass index of ≥25 kg/m2 were recruited for the study. The participants were treated with a 90°C dry sauna for 15 minutes, twice daily for 4 consecutive days. To assess the quality of life, all participants completed the 5 level EQ-5D questionnaires and the EQ-Visual Analog Scale. Study parameters were measured on the same day prior to commencing the sauna sessions in a fasted state and 2 days after the last sauna session. Results: The average age was 62.3±9.5 years; 84.2% of the participants were female. The mean body mass index was 28.5±2.4 kg/m2. Dry sauna significantly improved the mean 5 level EQ-5D index scores from 0.83±0.12 to 0.89±0.11 and increased the mean EQ-Visual Analog Scale from 79.0±15.2 to 91.1±9.7. However, there were no significant changes in body mass index, blood pressure, heart rate, or body composition before and after the 8-session sauna therapy. Conclusion: Dry sauna improved the health-related quality of life of obese patients without adverse events. Further clinical studies in larger study populations are needed to verify these findings and provide concrete evidence for obesity treatment.

Acute suppurative thyroiditis (AST) is a rare disease of the thyroid gland that results from anatomical abnormalities, such as pyriform sinus fistula. However, in some case reports, patients with AST did not have anatomical abnormalities, including a report in which children with acute leukemia developed AST after chemotherapy. We report a case of AST in an adult with a hematologic disorder treated with chemotherapy. Although he was initially treated with parenteral antibiotics, surgical intervention was performed due to progressive worsening of AST. He recovered after surgical intervention and had no anatomical abnormality.

Serum Preadipocyte Factor 1 Levels Are Not Associated with Bone Mineral Density among Healthy Postmenopausal Korean Women

최훈성,김상욱,조은희 대한내분비학회 2017 Endocrinology and metabolism Vol.32 No.1

Background: Multipotent mesenchymal stem cells can differentiate into adipocytes or osteoblasts through closely regulated lineagecontrolprocesses. However, adipocyte precursor cells release preadipocyte factor 1 (Pref-1), which inhibits the differentiation ofmesenchymal stem cells into mature adipocytes and osteoblasts. Previous studies have also reported an inverse association betweenPref-1 levels and bone mineral density (BMD) among patients with anorexia nervosa. Methods: In this retrospective study, we examined the correlations between Pref-1 levels and BMD among 124 healthy postmenopausalwomen (>50 years old). The patients had provided information regarding their clinical characteristics, and underwent bloodtesting and serum Pref-1 testing. Results: The subjects’ mean age was 59.9±7.1 years and the median time since menopause onset was 9.1 years. A history of osteoporoticfracture was identified in 23 subjects (19%). Serum Pref-1 levels were not significantly correlated with BMD values at thelumbar spine (R2=0.038, P=0.109), femur neck (R2=0.017, P=0.869), and total hip (R2=0.041, P=0.09), and multivariate analyseswith adjustment for age and body mass index also did not detect any significant correlations. Subgroup analyses according to a historyof fracture also did not detect significant associations between Pref-1 levels and BMD values. Conclusion: In our study population, it does not appear that serum Pref-1 levels are significantly associated with BMD values andosteoporosis.
