Proprotein convertase subtilisin/kexin type 9 (PCSK9) and clinical outcomes in dialysis patients.

Proprotein convertase subtilisin/kexin type 9 (PCSK9), a factor accelerating the degradation of LDL receptors, was associated with a gender-dependent risk for cardiovascular (CV) events in the general population and with all-cause and CV mortality in two relatively small studies in black Africans and South Korean haemodialysis patients. The effect modification by gender was untested in these studies. The study enrolled 1188 dialysis patients from the Prospective Registry of The Working Group of Epidemiology of Dialysis Region Calabria (PROGREDIRE) cohort. PCSK9 was measured by colorimetric enzyme-linked immunosorbent assay. The primary outcomes were all-cause and CV mortality. Statistical analysis included Cox regression analysis and effect modification analysis. During a median 2.9-year follow-up, out of 494 deaths, 278 were CV-related. In unadjusted analyses, PCSK9 levels correlated with increased all-cause (HRfor1ln unit increase: 1.23, 95% CI 1.06-1.43, p =.008) and CV mortality (HRfor1ln unit increase: 1.26, 95% CI 1.03-1.54, p =.03). After multivariate adjustment, these associations were no longer significant (all-cause mortality, HRfor 1 ln unit increase: 1.16, 95% CI .99-1.36, p =.07; CV mortality, HRfor1ln unit increase: 1.18, 95% CI .95-1.46, p =.14). However, in fully adjusted interaction analyses, a doubling in the risk of this outcome in women was registered (Women, HRfor1ln unit increase: 1.88, 95% CI 1.27-2.78, p =.002; Men, HRfor1ln unit increase: 1.07, 95% CI .83-1.38, p =.61; p for effect modification: .02). PCSK9 levels are unrelated to all-cause mortality in haemodialysis patients but, like in studies of the general population, independently of other risk factors, entail a doubling in the risk of CV events in women in this population.

Impact of the COVID-19 Pandemic on Obesity, Metabolic Parameters and Clinical Values in the South Korean Adult Population

This study aimed to evaluate the effects of the COVID-19 pandemic on obesity, metabolic parameters, and clinical values in the South Korean population. Data from the seventh and eighth National Health and Nutrition Examination Surveys were analyzed, comprising 3560 participants in 2018 (pre-COVID-19) and 3309 participants in 2021 (post-COVID-19). The study focused on adults aged 19 years and older who were overweight (BMI ≥ 25 kg/m2). The results showed a significant increase in waist circumference (approximately 2 cm), BMI (approximately 0.11 kg/m2), systolic blood pressure, fasting blood sugar (1.76 mg/dL higher), and glycated hemoglobin (0.14% higher) in the post-COVID-19 group compared to the pre-COVID-19 group. Additionally, the prevalence of hypercholesterolemia increased by 4% after the COVID-19 pandemic. These findings suggest an increased risk of obesity, abdominal obesity, and metabolic disorders, such as blood sugar disorders, in the post-COVID-19 period. Urine analysis revealed abnormal findings, including occult blood, urobilinogen, hematuria, proteinuria, ketone urea, glycosuria, and bacteriuria. The study highlights the negative impact of lifestyle changes, such as reduced physical activity and social gatherings, on physical vital signs and clinical values during the COVID-19 pandemic.

Empty old graves of the Korean War Hill Fight

The Hill Fight of the Korean War constitutes an important chapter of the formative military conflict of the mid-twentieth century where the South Korean and other UN forces confronted the Chinese and North Korean forces. Currently, it has become a vital site of contested memory, especially in relation to the growing contest of power between the United States and the People’s Republic of China. Describing South Korea’s recent initiative of missing in action (MIA)/killed in action (KIA) accounting activities on these old battlegrounds since 2000, this article looks at how public actions concerning the remains of war are intertwined with changing geopolitical conditions. This will be followed by a reflection on the limits of the prevailing art and technology of war-remains accounting.

Where’s the beef?: the politics of health care reform in South Korea

Background: In February 2024, the South Korean government released a policy proposal for healthcare reform, with one of the main pillars being increased medical school admissions. This policy has sparked intense opposition from the physicians’ top association. Most importantly, interns and residents—the bedrock of the medical workforce in Korean hospitals—began to leave en masse. Consequently, a medical crisis emerged, in which many medical and surgical procedures were delayed.Current Concepts: According to studies on comparative health policy and systems, the crisis could be attributed to the unique characteristics of the Korean healthcare system, in which the administration and doctors have failed to establish a substantive dialogue through which policy options are examined and deliberated. These dynamics necessitated the establishment of an institutional space for interest group politics, causing both to suffer from a lack of action repertoires. The stalemate we witness reflects the enduring patterns of the same issue.Discussion and Conclusion: To ensure the success of the current initiative, institutional arrangements must be established in which policymakers and physicians make a credible commitment to each other. Alternatives, for instance, include reactivating and regularizing the Health and Medical Services Policy Deliberation Committee, which could pave the way for establishing a venue where key stakeholders can discuss future agendas, such as how to ensure improved accessibility to “essential” care and mitigate its subnational variation, thereby creating a long-term vision for new health system governance in South Korea.

Clinicopathological Differences between Right and Left Colorectal Cancer by Sex

Background: Until now, studies on colorectal cancer (CRC) have focused on clinicopathological characteristics based on location without considering sex differences. However, as men and women have fundamentally different physiological characteristics, research results in the clinical field are limited. We aimed to elucidate the differences in the clinicopathological characteristics between right-sided CRC (RCC) and left-sided CRC (LCC) according to sex. Methods: We classified 1492 South Korean patients with no history of colon surgery between July 2005 and June 2015 based on tumor location and sex. For these patients, differences in the clinical characteristics according to sex were compared using univariate and multivariate analyses. Results: Of the 1269 patients, 951 (74.9%) had LCC, and 318 (25.1%) had RCC, making LCC approximately three times more common than RCC. When sex was not taken into account, patients with RCC had significantly higher rates of anemia and undifferentiated cancers than the rates in those with LCC. Even considering sex, anemia and undifferentiated cancer were more prevalent in RCC than in LCC in both men and women. In contrast, age over 65 years and abnormal white blood cell count differed between RCC and LCC only in women. Conclusions: The clinicopathologic characteristics of CRC vary according to the location and sex. Therefore, sex must be considered as a fundamental characteristic of personalized treatment.

Deconstructing subjective unmet healthcare needs: a South Korean case study with policy implications

BackgroundDespite widespread efforts by many countries to reduce the prevalence of unmet healthcare needs within their populations, there remains a scarcity of research systematically exploring the components of these needs.ObjectivesThis study aims to deconstruct subjective unmet healthcare needs into two distinct components: the experience of subjective healthcare needs (the “Needs” component) and the experience of unmet needs contingent on those healthcare needs (the “Unmet” component).MethodsThis analysis utilizes data from 13,359 adults aged 19 or older, collected through the 2018 Korea Health Panel survey, with the aim of minimizing the influence of the coronavirus disease 19 pandemic. The two dependent variables are the experience of subjective healthcare needs and whether these needs have been met. The independent variables include 15 socio-demographic, health, and functional characteristics. The study employs both a population proportion analysis and a multivariable bivariate probit model with sample selection.ResultsIn South Korea, 11.6% (CI [confidence interval] = 11.0–12.3%) of the population experienced subjective unmet healthcare needs. Upon deconstructing these, 96.7% (CI = 96.2–97.1%) of the population exhibited the Needs component, and 12.0% (CI = 11.4–12.7%) displayed the Unmet component. Each independent variable showed different associations between the two components. Furthermore, effective interventions targeting the characteristics associated with each component could reduce the proportion of the population experiencing subjective unmet healthcare needs from 11.6 to 4.0%.ConclusionSouth Korea faces a significant challenge due to the considerable prevalence of subjective unmet healthcare needs. To address this challenge effectively, the universal healthcare coverage system should adapt its approach based on the characteristics associated with both the Needs and Unmet components of subjective unmet healthcare needs. To achieve this goal, it is highly recommended that the government prioritize strengthening community-based primary healthcare, which currently suffers from insufficient resources.

Prevalences and Interrelationships of Post COVID-19 Fatigue, Sleep Disturbances, and Depression in Healthy Young and Middle-Aged Adults

Background: An evaluation of the persistence of symptoms following COVID-19 in economically active young and middle-aged adults is crucial due to its significant socioeconomic impact resulting from compromised work performance. Methods: A prospective, multicenter study at 12 South Korean hospitals from January to December 2022 involved telephone interviews along with validated questionnaires. Results: Among 696 participants with a median age of 32 and no prior diagnoses, 30% of participants experienced persistent fatigue, while 21.4% suffered from sleep disturbance at 6 months following infection. Additionally, approximately 25% of the participants exhibited depression that endured for up to 6 months. Symptomatic individuals at 3 months exhibited a significantly higher prevalence of persistent fatigue, sleep disturbances, and depression at 6 months compared to those who remained asymptomatic. Notably, sleep disturbance and persistent fatigue at 3 months emerged as significant independent predictors of the presence of depression at 6 months. Conclusions: Even among young and middle-aged healthy adults, prolonged fatigue, sleep disturbance, and depression exhibit a significant prevalence and persisted for up to 6 months. Therefore, implementing a workplace management protocol for these symptoms is essential to mitigate the socioeconomic burden caused by the impairment of work efficiency.

Cumulative effect of unemployment on suicide mortality in South Korean workers (2018-2019).

While unemployment is known to increase the risk of suicide, its cumulative effect remains underexplored. This study investigates how unemployment affects suicide mortality and whether the effect varies based on the number of unemployment spells using two years of nationwide data. Using the data from the National Statistical Office and Employment Insurance Database for 2018 and 2019, we identified an average of 2365 cases of suicide over two years among 7.76 million workers aged 25-64 years who had been employed within one year before their suicide. The number of unemployment spells was counted using the employment history of the past five years. We calculated crude suicide mortality rates per 100 000 population, age- and sex- standardized mortality rates (SMRs), and proportionate mortality rates (PMRs) for suicide. Over the two years, the crude suicide rate was 30.0 per 100 000 among the general population and 30.5 among workers. Workers with no unemployment spells in the past five years had a significantly lower SMR (0.44; 0.42-0.46), while those with four or more unemployment spells had a significantly higher SMR (3.13; 2.92-3.35) than the general population. These findings were consistent across all sex and age groups. Additionally, workers with four or more unemployment spells had a significantly higher PMR than the general population. The impact of unemployment on suicide mortality intensifies as the number of unemployment spells increases. These results underscore the necessity for additional social and psychological support along with economic assistance for individuals facing recurrent unemployment.

Planned Behavior in the Use of Dating Apps by Women in Korea

While South Koreans tend to quickly adopt new technologies, such as mobile apps, without facing technological difficulties, this population uses dating apps at a relatively low rate compared with Western countries. The current study employes the Theory of Planned Behavior (TPB) to examine psychological factors, as opposed to technological factors, to explain why South Koreans—particularly female young adults—rarely use dating apps to find potential romantic partners. Participants were 309 women who completed an online survey assessing their attitudes toward dating apps, subjective norms regarding dating apps, and perceived risks. As for behavioral control, factors of the original TPB were collected, and the relationships among these factors were analyzed. The results indicated that the initially suggested model did not show an acceptable fit of the data. Among the three factors, attitude towards dating apps was the most important in predicting intention, while actual usage of the apps negatively affected future intentions. Implications and future research directions are discussed.

Differences in Exercise Stress, Job Satisfaction, Intention to Quit Exercise, and Quality of Life According to the Psychological Abuse Experiences of Elite Male Athletes

This study aimed to further understand psychological abuse in sports and contribute to the development of elite sports and athletes’ persistent performance by identifying the causal effects of psychological abuse on elite athletes’ exercise stress, job satisfaction, intention to quit exercise, and quality of life (QOL). Data were collected from 363 elite South Korean male athletes (ages ≥ 20 years) from August to September 2023. The independent variable for comparative analysis was the presence or absence of psychological abuse in elite male athletes by coaches. The participants were divided into two groups: a non-abuse-experienced group (Group 1) and an abuse-experienced group (Group 2). Participants’ demographic and athletic background information (e.g., career and sport) were also collected. This study showed that the three factors (exercise stress, intention to quit exercise, and QOL) were higher in Group 2 than in Group 1. These findings provide a meaningful analysis of the impact of psychological abuse on the mental health, persistence, and overall QOL of elite male athletes that can be used to develop countermeasures and policies against psychological abuse that threatens the mental health of elite athletes.

Sanxingdui in the Historiography of the Republic of Korea

Тhe purpose of this article is to analyze the degree of archaeological and scientific knowledge on the territory of the Republic of Korea of the site and culture of Sanxingdui, discovered in 1986 in the Sichuan province of the People’s Republic of China. The Sanxingdui site entered world historiography due to the finds of magnificent bronze objects – such as face masks, human statues and “sacred trees”. The sources of the work were 28 printed works published in the Republic of Korea, the authors or translators of which were South Korean specialists. As a result of the analysis of South Korean publications that used materials from the Sanxingdui site or culture, the following conclusions can be drawn. The site and culture of Sanxingdui did not go without deserved attention in South Korean historiography. The main types of publication of Sanxingdui materials are chapters in general works on the history and culture of ancient China, as well as articles on Chinese and East Asian mythology and linguistics. A whole series of research projects under the leadership of Professors Kim Hyunja and Kim Seonja is devoted to the reflection of mythological images in the Sanxingdui culture. Also in the Republic of Korea, two Masters thesis were defended in which materials from the Sanxingdui site were used to solve applied problems. The site and culture of Sanxingdui have left a clear mark on South Korean historiography, though not always original.

The growth patterns of firms in the industrial value chain using the hidden markov model: Evidence from the Korean semiconductor industry

Having steadily grown over the last 40 years, the semiconductor industry in South Korea has emerged as one of the leading industries in the world. However, it has recently entered a period of great change because of the volatility in the global value chain caused by trade conflicts and protectionism in the pursuit of technological sovereignty by countries. To cope with these changes, the South Korean government has endeavoured to strengthen the competitiveness of domestic materials and equipment segments, which are the backbone of the semiconductor industry. Nevertheless, most previous studies on the semiconductor industry in South Korea focused on the downstream of the value chain (which means the manufacturing of finished components). However, only a few attempts were made to investigate the upstream part of the industry, that is, materials and equipment segments. Therefore, this study analyses the growth patterns of firms engaged in the Korean semiconductor industry value chain, including finished components, materials, and equipment. For this objective, we applied the Hidden Markov Model to time-series sales data collected from 1998 to 2019 for 1,259 firms in the value chain. The analysis results indicated that the growth of these firms could be modelled using six stages, based on which nine patterns of growth were identified. This study proposes a novel data-driven approach for tracking firm growth across the domestic industry value chain from a longitudinal perspective. Thus, we provide valuable policy insights for nurturing the domestic industry’s value chain.

South Korean Nurse Residency Program for New Graduates: A Posttest Study.

Turnover rates among newly graduated nurses are high, increasing the workload for other nurses and hampering organizational productivity. This study investigates the effects of a nurse residency program (NRP), examining clinical competence, job satisfaction, organizational socialization, turnover intention, and turnover rates. This study was conducted among newly employed graduate nurses in South Korea. Participants (N = 167) included nurses with less than 6 months of experience (NRP group, n = 52; control group, n = 115). The current results were measured 1 year after initiation of the NRP. The NRP group showed significantly lower turnover intention and turnover rates and substantially better clinical competence, job satisfaction, and organizational socialization. Even when applied in the unique South Korean cultural and medical context, the NRP improved job performance and satisfaction as well as organizational socialization and reduced turnover rates and turnover intention among new nurses. Therefore, a systematized NRP should be actively used when new nurses are onboarded. [J Contin Educ Nurs. 202x;5x(x):xx-xx.].

Genetic and Environmental Influences on Perceived Stress in South Korean Twins.

Researchers have proposed that culture significantly influences perceived stress (PS). To date, however, twin studies on PS have been conducted mostly in western, individualistic cultures, which demonstrate that PS due to controllable (personal) life events is more heritable than PS due to uncontrollable (network) life events. This study aimed to investigate genetic and environmental influences on PS in South Korean twins. South Korea practices a dominant collectivist culture. In total, 1372 twin individuals (mean age = 22.4 ± 2.5 years) completed an online survey on PS, which consisted of the scales, Friendship, Academic Stress, Future Career, Family Conflicts, and Family Financial Difficulties (FFD). Friendship, Academic Stress, and Future Career can be considered PS due to personal life events, and Family Conflict and FFD, PS due to network life events. The general sex-limitation model-fitting analysis revealed the absence of qualitative or quantitative sex differences in genetic and environmental influences. Specifically, additive genetic influences were predominant for Friendship (63%), Academic Stress (67%), and Future Career (57%) for both sexes, with the remaining variance attributable to nonshared environmental influences. In contrast, shared environmental influences were largest for Family Conflict (47% for both genders) and FFD (64% for males, 63% for females) with no significant genetic effects. Despite known cultural differences in the means and variances of PS, South Korean twins exhibited significant genetic effects in PS due to personal life events and large shared environmental effects in PS due to network life events, which is similar to western samples.

The role of cooperative R&D in innovation performance of SMEs: evidence from South Korean materials, parts, and equipment firms

ABSTRACT Can cooperative R&D between SMEs and other organisations enhance innovation performance? This study utilises a mixed-methods approach to examine the impact of voluntary cooperative R&D and gain an improved understanding of the mechanisms that facilitate innovation outcomes. The analysis uses a firm-level secondary dataset from South Korea’s M-P-E industry for the period between 2005 and 2020, as well as in-depth expert interviews. The findings indicate that collaboration between SMEs, universities, and government research institutes (GRI)s positively impacts innovation performance. The expert interviews confirm that partnerships with academic institutions and research organisations help bridge the gap between creating key innovations and their commercialisation. The results also show that government R&D support facilitated collaborations between suppliers and buyers, which in turn led to improved innovation outcomes. This implies that providing R&D subsidies to SMEs could be a useful strategy for governments seeking to bolster their technological innovation. Policy implications are further discussed in the conclusion.

Association of the Type of Public Pension With Mental Health Among South Korean Older Adults: Longitudinal Observational Study.

As income and health are closely related, retirement is considered undesirable for health. Many studies have shown the association between pension and health, but no research has considered the association between contribution-based public pensions or their types and health. This study investigates the association between the type of contributory public pension and depressive symptoms among older adults. We analyzed the data of 4541 older adults who participated in the South Korea Welfare Panel Study (2014-2020). Depressive symptoms were measured using the 11-item Center for Epidemiologic Studies Depression scale. Public pensions in South Korea are classified into specific corporate pensions and national pensions. For subgroup analyses, pensioners were categorized according to the amount of pension received and the proportion of public pension over gross income. Analyses using generalized estimating equations were conducted for longitudinal data. Individuals receiving public pension, regardless of the pension type, demonstrated significantly decreased depressive symptoms (national pension: β=-.734; P<.001; specific corporate pension: β=-.775; P=.02). For both pension types, the higher the amount of benefits, the lower were the depression scores. However, this association was absent for those who received the smaller amount among the specific corporate pensioners. In low-income households, the decrease in the depressive symptoms based on the amount of public pension benefits was greater (fourth quartile of national pension: β=-1.472; P<.001; second and third quartiles of specific corporate pension: β=-3.646; P<.001). Our study shows that contributory public pension is significantly associated with lower depressive symptoms, and this association is prominent in low-income households. Thus, contributory public pensions may be good income sources for improving the mental health of older adults after retirement.

Abstract PO3-08-12: Oncologic Safety and Preventive Impact of Nipple-Sparing Mastectomy in BRCA1/2 Mutation Carriers: A Multicenter Retrospective Study of the Korea Robot-Endoscopy Minimal Access Breast Surgery Study Group (KoREa-BSG)

Abstract Purpose: Nipple-sparing mastectomy (NSM) is known for its excellent cosmetic results and acceptable oncologic safety. However, evidence supporting NSM in breast cancer (BC) patients carrying pathogenic variant (PV) or likely pathogenic variant (LPV) in BRCA1/2 genes is still limited. This study aims to evaluate the oncologic safety of NSM in BC patients and examine its preventive effect in unaffected individuals with BRCA1/2 PV/LPV. Methods: In this multicenter, retrospective study was conducted by the Korea Robot-Endoscopic minimal access Breast Surgery study Group (KoREa-BSG). We evaluated data from women who underwent NSM and BRCA1/2 genetic testing across 19 South Korean institutions. This study included BC patients aged between 20 and 80 years who had NSM and BRCA1/2 genetic testing between January 2008 and December 2018. Patients with distant metastasis at the initial diagnosis were excluded. Results: A total of 786 women, encompassing 906 NSM cases, were included. This population comprised 120 patients who underwent bilateral NSM, 666 with unilateral NSM for unilateral BC. Among them, 214 who received neoadjuvant chemotherapy. The median follow-up period was 62 months, with an age range of 26-74 years (median 44). Sentinel lymph node biopsy was carried out in 74.7% of cases. In the bilateral NSM cohort (n=120), 36 were bilateral BC patients, 41 were unaffected carriers of BRCA1/2 PV/LPV who underwent bilateral risk-reducing NSM (RRNSM), and 33 presented with unilateral BC with BRCA1/2 PV/LPV. In the subset of 33 patients who underwent contralateral RRNSM for unilateral BC, incidental ductal carcinoma in situ (DCIS) was discovered in two cases. In comparing NSM outcomes according to BRCA status, we found no significant difference in local recurrence (LR) between BC patients with BRCA1/2 PV/LPV (n=172) and those without BRCA1/2 PV/LPV (n=592) (LR rates: 11 in BRCA1/2 PV/LPV vs. 45 in non-carriers; p = 0.7965). Of the 172 BRCA1/2 PV/LPV carriers who did not undergo RRNSM, contralateral BC occurred in 11 patients (6.4%), while no recurrence was recorded in the RRNSM group. Conclusions: NSM appears to be a feasible option in BC patients with BRCA1/2 PV/LPV. While the long-term impact of NSM on breast cancer prevention in BRCA1/2 PV/LPV carriers requires further investigation, current evidence suggests that NSM could serve as an effective risk-reducing strategy.

Economic effects of the hydrogen fuel cell sector in South Korea: An input-output analysis

The South Korean government plans to deploy approximately 200–300 MW of hydrogen fuel cells (FCs) annually from 2023 to 2036, all of which will be connected to the national power system, not used for self-consumption. The government is requesting quantitative information on the economic effects of the FC sector. In response to this request, this study delves into the four economic effects of expanding FC use in South Korea adopting the input-output (IO) approach for the first time in the literature. More specifically, it investigates how much investment or production in the FC sector affects other sectors. Economic performance, such as production, value-added, jobs, and wages, is the subject of investigation. The FC sector is dealt with separately as the FC-manufacturing (FC-M) sector and the FC-equipping and operating (FC-E&O) sector. The 2019 IO table, 34-sector classification, demand-driven model of the IO approach, and exogenization of the FC sector are used. The results show that each unit of investment or production in the FC-M and FC-E&O sectors triggers 2.328 and 1.793 units of production, 0.785 and 0.967 units of value-added, and 0.346 and 0.575 units of wages, for each sector, respectively, across the economy. KRW 1 billion of production or investment in the two sectors creates approximately 7.7 and 3.8 jobs, respectively. These figures can be useful for exploring the economic effects of FC deployment in the future on the South Korean economy.

Attitudes of South Korean consumers toward the prudent use of antimicrobials in livestock animals

Antimicrobial resistance (AMR) in livestock is a complicated and multi-sectoral risk that threatens public health in the interactions between humans, animals, and environment. Through their increased awareness of AMR issues, consumers can make a significant impact on regulations and strategies to reduce or eliminate the use of antimicrobials use. This study aims to provide evidence-based data for promoting the prudent use of antimicrobials (PUA) in the livestock industry to reduce the risk of AMR and increase animal welfare by identifying consumers' intentions to support PUA practices in livestock farming. An online survey was conducted on 1000 respondents in South Korea to examine their intention to pay more for PUA practices in livestock farming at state and individual levels against their pro-animal attitude, risk perception of antimicrobial overuse, trust in antimicrobial overuse control, and perceived value of PUA practices. The survey data was analyzed using multiple linear regression to identify the determinants of Korean consumers' support for PUA practices. Approximately 86.3% of the respondents supported government-level spending for PUA in livestock farming, and the same portion of respondents intended to pay more for livestock products that complied with the PUA principle. The four attitudinal variables—pro-animal attitude, consumers' risk perception, trust in antimicrobial resistance control, and perceived value of PUA—positively affected both state- and individual-level support. Overall, our findings highlight the Korean consumers' demand for reducing the risk of AMR and their perceived universal value of PUA for humans and animals.
