Park Chan-kyong is the second artist selected for the \"MMCA Artist Studies\" series. Since the late 1980s, Park has been a member of a community of critics writing art and organizing exhibitions through forums such as the Research Society for Art Criticism (misul bipyeong yeonguhoe), Forum A, BOL. Park took his first steps as an artist with the solo exhibition Black Box: The Memory of Cold War Images, held at the Kumho Museum in 1997, and has since continued to produce film and video works critically examining the Cold War, Korean modernity, and colonialism. Under the title Red Asia Complex, this book examines, from various perspectives, the nearly thirty-years trajectory of Park Chan-kyong's art and writing.--Gallery Website.

The objective of this study was to investigate the prevalence, management, and comorbidities of diabetes among Korean adults aged 30 years and older. This study used 2013 to 2016 data from the Korea National Health and Nutrition Examination Survey, a nationally-representative survey of the Korean population. Diabetes was defined as fasting glucose ≥126 mg/dL, current use of antidiabetic medication, a previous history of diabetes, or glycosylated hemoglobin (HbA1c) ≥6.5%. In 2016, 14.4% (approximately 5.02 million) of Korean adults had diabetes. The prevalence of impaired fasting glucose was 25.3% (8.71 million). From 2013 to 2016, the awareness, control, and treatment rates for diabetes were 62.6%, 56.7%, and 25.1%, respectively. People with diabetes had the following comorbidities: obesity (50.4%), abdominal obesity (47.8%), hypertension (55.3%), and hypercholesterolemia (34.9%). The 25.1%, 68.4%, and 44.2% of people with diabetes achieved HbA1c <6.5%, blood pressure <140/85 mm Hg, and low density lipoprotein cholesterol <100 mg/dL. Only 8.4% of people with diabetes had good control of all three targets. This study confirms that diabetes is as an important public health problem. Efforts should be made to increase awareness, detection, and comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

Chronic regional pain syndrome (CRPS) is an inflammatory and neuropathic pain disorder characterized by the involvement of the autonomic nervous system with sensory, autonomic, motor, skin, and bone changes. At present, universally accepted consensus criteria for CRPS are not yet established, despite the diagnostic criteria proposed by the International Association for the Study of Pain (IASP). Various hypotheses for the pathophysiology of CRPS have been proposed; as a result, current therapeutic modalities are varied. General epidemiological data on CRPS are necessary for effective management. However, recent data on the epidemiology of CRPS in Korea are scarce. The aim of this study was to evaluate the incidence and other epidemiological features of CRPS in the general population in Korea. In this study on the epidemiology of CRPS in Korea, population-based medical data acquired from 51,448,491 subscribers to the National Health Insurance Service (NHIS) from 2011 to 2015 were analyzed, including the incidence, distribution by the CRPS type, regional distribution, monthly distribution, medical costs, and healthcare resource-utilization. The findings indicated that the incidence of CRPS in Korea was 29.0 per 100,000 person-years in 2015 and was correlated with patient age and sex. CRPS types included type I (63%) and type II (37%); moreover, the number of individuals with CRPS I have shown a growing trend since 2011. There was no monthly distribution, but there was regional variation according to the province. The medical departments managing CRPS I the most were orthopedics, internal medicine, anesthesiology and pain medicine, in order; however, patients with CRPS spent more money per visit in the departments of rehabilitation medicine, and anesthesiology and pain medicine. The incidence rate of CRPS in Korea was 29.0 per 100,000 person-years with an increasing trend, which was correlated with patient age in the 70s and female sex. CRPS type I was more common than CRPS type II; in addition, constant increase in medical expenses, regional imbalance, and differences in medical expense among medical specialties should be considered for early management of patients to reduce the disease burden in Korea. Sharing of knowledge about the diagnostic criteria of CRPS are also needed.

Clear aligners have transformed orthodontic treatment; however, they exhibit limited effectiveness in closing extraction spaces due to cumulative movement errors and excessive tipping. This proof-of-concept study introduces an innovative multi-step finite element method (FEM) for simulating sequential clear aligner applications in extraction space closure. A compensation protocol, incorporating an adaptive iterative FEM, was compared with a conventional protocol, and movement precision and unintended tipping were analyzed. The results demonstrated that the compensation protocol significantly reduced tipping (≤ 1°) compared to the conventional approach (> 6°) and minimized the mismatch between crown and root movements. Additionally, the compensation protocol consistently maintained a high achievement rate, preventing the progressive loss of movement efficiency typically observed with conventional protocols. It also provided a more controlled vertical displacement, thereby reducing unwanted extrusion. Furthermore, synchronized crown-root movement contributed to more stable bodily movement, ensuring that teeth followed the intended trajectory more accurately. These findings highlight the potential of the compensation protocol in improving treatment predictability and accuracy in extraction cases. This approach enables systematic adjustment of aligner design based on actual tooth movement, offering an optimized strategy for clear aligner biomechanics and potentially enhancing clinical outcomes in orthodontic treatment.

In this study, the causes of the increase in global mean tropical cyclone translation speed (TCTS) in the post-satellite era were investigated. Analysis reveals that the global-mean TCTS increased by 0.31 km h−1 per decade over the last 36 years, but the steering flow controlling the local TCTS decreased by −0.24 km h−1 per decade in the major tropical cyclone (TC) passage regions. These values correspond to a change of 5.9% and −5.6% during the analysis period for the mean TCTS and steering flow, respectively. The inconsistency between these two related variables (TCTS and steering flows) is caused by relative TC frequency changes according to basin and latitude. The TCTS is closely related to the latitude of the TC position, which shows a significant difference in mean TCTS between basins. That is, the increased global-mean TCTS is mainly attributed to the following: (1) an increase (4.5% per decade) in the relative proportion of the North Atlantic TCs in terms of global TC's position points (this region has the fastest mean TCTS among all basins); and (2) the poleward shift of TC activities. These two effects account for 76.8% and 25.8% of the observed global-mean TCTS trend, respectively, and thus overwhelm those of the slowing steering flow related to the weakening of large-scale tropical circulation, which leads to a global mean increase in TCTS. Given that TC activity in the North Atlantic is closely related to the Atlantic Multi-decadal Oscillation and a poleward shift of TC exposure is likely induced by global warming, the recent increase in the global-mean TCTS is a joint outcome of both natural variations and anthrophonic effects.

This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data. This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated. In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of <6.5%. Moreover, only 11.5% of subjects with diabetes met all three targets of glycosylated hemoglobin, blood pressure, and LDL-C. The percentage of energy intake from carbohydrates was higher in diabetes patients than in those without diabetes, while that from protein and fat was lower in subjects with diabetes. The high prevalence and low control rate of diabetes and its comorbidities in Korean adults were confirmed. More stringent efforts are needed to improve the comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

The goal achievement rate of patients' low-density lipoprotein cholesterol (LDL-C) levels and prescribing pattern of statin potency should be continuously monitored in a real-world clinical setting. This study aimed to describe the comprehensive status of LDL-C management. Patients first diagnosed with cardiovascular diseases (CVDs) between 2009 and 2018 who were followed for 24 months. LDL-C levels, its changes from baseline, and intensity of statin prescribed were evaluated four times during follow-up. Potential factors associated with goal achievement were also identified. The study included 25,605 patients with CVDs. At diagnosis, the goal achievement rates of the LDL-C level were 58.4, 25.2, and 10.0% for targets of < 100, < 70, and < 55 mg/dL, respectively. The proportion of moderate- and high-intensity statin prescription significantly increased over time (all p < 0.01). Nevertheless, LDL-C levels significantly decreased at 6 months and increased at 12 and 24 months following therapy compared with baseline values. Glomerular filtration rate (GFR) (15 - 29 and < 15 mL/min/1.73m ) and accompanying diabetes mellitus were significantly associated with the goal achievement rate. Despite the need for active LDL-C management, the goal achievement rate and prescribing pattern were insufficient after 6 months. In cases with severe comorbidities, the goal attainment rate significantly increased; however, a more aggressive statin prescription was needed even in patients without diabetes or with normal GFR. The prescription rate for high-intensity statins increased over time, but was still low. In conclusion, physicians should aggressively prescribe statins to increase the goal achievement rate in patients with CVDs.

In this study, we sought to isolate Salmonella Enteritidis-specific lytic bacteriophages (phages), and we found a lytic phage that could lyse not only S. Enteritidis but also other Gramnegative foodborne pathogens. This lytic phage, SS3e, could lyse almost all tested Salmonella enterica serovars as well as other enteric pathogenic bacteria including Escherichia coli , Shigella sonnei , Enterobacter cloacae , and Serratia marcescens . This SS3e phage has an icosahedral head and a long tail, indicating belong to the Siphoviridae . The genome was 40,793 base pairs, containing 58 theoretically determined open reading frames (ORFs). Among the 58 ORFs, ORF49, and ORF25 showed high sequence similarity with tail spike protein and lysozyme-like protein of Salmonella phage SE2, respectively, which are critical proteins recognizing and lysing host bacteria. Unlike SE2 phage whose host restricted to Salmonella enterica serovars Enteritidis and Gallinarum, SS3e showed broader host specificity against Gram-negative enteric bacteria; thus, it could be a promising candidate for the phage utilization against various Gram-negative bacterial infection including foodborne pathogens.

The bidirectional relationship between low high-density lipoprotein cholesterol (HDL-C) and glucose intolerance is well established. Recent studies suggested an association of lipid variability with various health outcomes. To investigate the combined effect of HDL-C levels and their variability on the risk of diabetes. A population-based cohort study. In all, 5,114,735 adults without known diabetes in the Korean National Health Insurance System cohort who underwent three or more health examinations from 2009 to 2013 were included. Visit-to-visit HDL-C variability was calculated using variability independent of the mean (VIM) and the coefficient of variation (CV). Low mean and high variability groups were defined as the lowest and highest quartiles of HDL-C mean and variability, respectively. Newly developed diabetes. There were 122,192 cases (2.4%) of incident diabetes during the median follow-up of 5.1 years. Lower mean or higher variability of HDL-C was associated with higher risk of diabetes in a stepwise manner, and an additive effect of the two measures was noted. In the multivariable-adjusted model, the hazard ratios and 95% CIs for incident diabetes were 1.20 (1.18 to 1.22) in the high mean/high VIM group, 1.35 (1.33 to 1.37) in the low mean/low VIM group, and 1.40 (1.38 to 1.42) in the low mean/high VIM group compared with the high mean/low VIM group. Similar results were observed when modeling the variability using CV and in various subgroup analyses. Low mean and high variability in HDL-C were independent predictors of diabetes with an additive effect. Both elevating and stabilizing HDL-C may be important goals for reducing diabetes risk.
