RESUMEN

This study investigates the impact of a minority language on international trade. Using the distance to Hunchun as an instrumental variable, and transaction-level customs data from 2000 to 2015, we investigate the causal impact of common Korean language on international trade between Chinese counties and South/North Korea. The results suggest that a 1% increase in the proportion of population speaking Korean will increase value share and transactions share in trade by 1.8% and 2.3%, respectively. These effects are more pronounced in trade with North Korea and in higher trade share regions. Furthermore, we show that the common Korean language exerts its influence through reducing communication barrier. The impact is mainly observed at the extensive margin rather than the intensive margin. These findings highlight the potential of leveraging minority languages to boost bilateral trade in developing countries.

RESUMEN

The use of observation-dependent methods for crop productivity and food security assessment is challenging in data-sparse regions. This study presents a transferable framework and applies it to North Korea (NK) to assess rice productivity based on climate similarity, transferable machine-learning techniques, and extendable multi-source data. We initially divided the primary phenological stages of rice in the study region and extracted dynamic rice distributions based on Moderate Resolution Imaging Spectroradiometer products and phenological observations. We compared the performances of four representative environmentally driven models (Linear Regression, back-propagation Neural Network, Support Vector Machine, and Random Forest) in simulating rice productivity using an extensive dataset that included multi-angle vegetation monitoring, climate variables, and planting distribution information. The framework integrated an optimal environmentally driven model with agricultural management practices for transferability to predict rice productivity in NK over multiple years. Additionally, two crop growth scenarios (whole growth period (WGP) and seeding-heading period (SHP)) were compared to assess pre-harvest forecasting capabilities and identify dominant factors. Finally, independent datasets from the Food and Agriculture Organization, World Food Program, and Global Gridded Crop Models were used to validate the magnitude and spatial distribution of the predicted results. The results showed that phenological identification based on remote sensing can accurately capture rice growth characteristics and map rice distribution. Random Forest outperformed other models in simulating rice productivity variation, with r-squares of 0.87 and 0.83 in the WGP and SHP, respectively. The solar-induced chlorophyll fluorescence, maximum temperature, and evapotranspiration collectively determined approximately 40 % of the variation in yield simulated using Random Forest. Conversely, planting areas contributed over 42 % of the variation in rice production. Compared to Food and Agriculture Organization statistics, the environmentally driven framework explained 78.72 % and 76.89 % of the production variation and 69.42 % and 71.15 % of the yield variation in NK under the WGP and SHP, respectively. Moreover, the environmental management-driven framework captured over 90 % of the yield variation. The predicted spatial pattern of rice productivity exhibited significant concordance with the World Food Program and Global Gridded Crop Model reports. In summary, the proposed transferable framework for crop productivity assessment contributes to early warnings of production reduction and has the potential for scalability across various crops and data-sparse regions.

RESUMEN

INTRODUCTION: Adolescent North Korean defectors are vulnerable due to harmful environments during defection, limited access to sex education in North Korea, and exposure to different sexual norms in South Korea. The purpose of this study was to investigate the sexual knowledge, attitudes, and sex education needs of North Korean refugee adolescents. METHODS: A cross-sectional, descriptive survey was administered to 102 North Korean refugee adolescents. RESULTS: The correct answer rate for questions on genital anatomy, physiology, masturbation, and contraception was less than 20%. The participants exhibited conservative attitudes toward female contraception, masturbation, and having friends of the opposite sex. A significant positive correlation was found between knowledge and the need for sex education. DISCUSSION: These results highlight the importance of tailored sex education in providing accurate information, improving sexual knowledge, fostering positive attitudes, and enabling healthy behaviors among adolescent North Korean defectors.

RESUMEN

Sika deer inhabiting South Korea became extinct when the last individual was captured on Jeju Island in Korea in 1920 owing to the Japanese seawater relief business, but it is believed that the same subspecies (Cervus nippon hortulorum) inhabits North Korea and the Russian Primorskaya state. In our study, mt-DNA was used to analyze the genetic resources of sika deer in the vicinity of the Korean Peninsula to restore the extinct species of continental deer on the Korean Peninsula. In addition, iSCNT was performed using cells to analyze the potential for restoration of extinct species. The somatic cells of sika deer came from tissues of individuals presumed to be Korean Peninsula sika deer inhabiting the neighboring areas of the Primorskaya state and North Korea. After sequencing 5 deer samples through mt-DNA isolation and PCR, BLAST analysis showed high matching rates for Cervus nippon hortulorum. This shows that the sika deer found near the Russian Primorsky Territory, inhabiting the region adjacent to the Korean Peninsula, can be classified as a subspecies of Cervus nippon hortulorum. The method for producing cloned embryos for species restoration confirmed that iSCNT-embryos developed smoothly when using porcine oocytes. In addition, the stimulation of endometrial cells and progesterone in the IVC system expanded the blastocyst cavity and enabled stable development of energy metabolism and morphological changes in the blastocyst. Our results confirmed that the individual presumed to be a continental deer in the Korean Peninsula had the same genotype as Cervus nippon hortulorum, and securing the individual's cell-line could restore the species through replication and produce a stable iSCNT embryo.

RESUMEN

Emerging pathogenic tick-borne viruses (TBVs) have attracted a great deal of attention due to their significant impact on human and animal health. A novel orthonairovirus named Dadong virus (DDV) was isolated from Haemaphysalis concinna ticks in the Changbai Mountain region on the China-North Korea border. DDV can induce cytopathic effects in mammalian and human cell lines. Phylogenetic analysis showed that it belongs to the genus Orthonairovirus, family Nairoviridae, exhibiting 72.4%-81.3% nucleic acid identity to Tofla orthonairovirus, known to cause lethal infection in IFNAR KO mice. The first serological evidence of DDV circulating in cattle and mice was also obtained, with 4.0% (1/25) of cattle and 2.27% (1/44) of mice seropositive for DDV. Further investigations, including serological surveys using human samples, are required to assess the public health risk posed by DDV.

RESUMEN

North Korean refugees exposed to traumatic events often experience a high recurrence of post-traumatic stress disorder symptoms. However, a post-traumatic growth programme has the potential to transform these traumatic events into increasing post-traumatic growth, reduced emotional stress and enhanced well-being. This study investigated the effects of a post-traumatic growth promotion programme on post-traumatic stress disorder recovery among North Korean refugees. Using a non-equivalent control group non-synchronised pretest-posttest design, 60 North Korean refugees who have been in South Korea for 6-8 or 12-13 years were assigned to the experimental (post-traumatic growth promotion programme; n = 30) or control group (post-traumatic growth promotion education brochure; n = 30). The programme comprised group sessions and discussions, each lasting 120 min/session, conducted twice a week for 5 weeks. Mindfulness, anxiety, depression, blood cortisol and post-traumatic growth were assessed at baseline, immediately after intervention and 4 weeks after intervention. The findings showed the programme was effective in significantly increasing post-traumatic growth and decreasing anxiety, depression and cortisol level. The two-way analysis of variance showed a significant interaction between groups and time. Consequently, this post-traumatic growth promotion programme can be utilised as a non-invasive, cost-effective and safe intervention for promoting post-traumatic growth and well-being among North Korean refugees.

RESUMEN

BACKGROUND: Amidst the COVID-19 pandemic, striking a delicate balance between sustaining economic activity and safeguarding public health has become a crucial concern. The border closures for COVID-19 prevention have further intensified concerns for North Korea, which conducts over 90% of its trade with China and Russia, countries sharing its borders. METHODS: This study aims to scrutinize North Korea's response to these competing imperatives by examining the impact of border closures on the country's trade dynamics with China and Russia. This study employed the difference-in-difference (DID) method to analyze transformations in North Korea's economic activity before and after the border closures, utilizing trade data and nighttime satellite imagery captured in 2019 and 2020. RESULTS: The results reveal that North Korea actively reoriented its trade priorities towards Russia and accorded precedence to its epidemic prevention system over its economy during the pandemic. A noticeable increase in imports of food and pharmaceuticals was observed, indicating a significant rise in the inflow of these essential commodities. CONCLUSION: The findings of this study suggest that during the early stages of the COVID-19 pandemic, North Korea placed significant policy emphasis on preserving public health. However, due to economic hardships and food shortages, if the pandemic persists in the long term, it indicates the possibility of partial or complete lifting of border closures to mitigate these challenges.

RESUMEN

As extensive as the concept of and the resources required for 'Health for Korean Unification' are, and due to the limited access to information on the state of health and medical care in North Korea, discussion on 'Health for Korean Unification' has tended to be intermittent and lacked concrete action plans. In this article, we specifically distinguished areas of cooperation and selected five executable agenda that meet the goals of international development cooperation: 1) Health security; 2) Easing the burden of major diseases; 3) Resilient healthcare system; 4) R&D cooperation; 5) Sustainable cooperation system. Then we provided corresponding strategic priorities and operative directions, in consideration of future military and political sanctions against North Korea. The strategies we outline are sustainable, preemptive for problems that might affect lives of South and North Korean citizens, and satisfy the unmet needs of the North Korean health system. Throughout the process, we utilized a special platform, the 'Korean Peninsula Healthcare Cooperation Platform,' designed to enable continual communication across sectors engaged in public health and medical care. By doing so, we take the first step to actually carry out the 'Health for Korean Unification,' which tended to have remained on the discussion agenda.

RESUMEN

The circular economy is emerging as an economic form to solve economic, environmental, and social problems around the world. In this regard, various countries and regions of the world are making every effort to establish and implement circular economy strategies and action plans. This paper discusses the Recycling Law adopted in the Democratic People's Republic of Korea and its characteristics. To this end, this paper examines the cases of legalization in various countries and regions around the world related to the circular economy and recycling and explains the contents and characteristics of the Recycling Law in the Democratic People's Republic of Korea concerning it. The findings are that (a) the more science and technology develop and the more complete the economic structure becomes, the more complete the legal environment related to the circular economy should become and (b) if the transition to the circular economy is to be implemented with strong obligations, the planning lever must be regulated as a legal obligation, and the state needs to use the planning lever to thoroughly implement circular economy-related goals and strategies. These findings can be used as a reference to prepare a legal environment for promoting the circular economy in countries pursuing the realization of a circular economy in a top-down way, and it will also help fill the gap in research on the legal environment for promoting the circular economy.

RESUMEN

Loneliness negatively predicts post-traumatic growth (PTG) among North Korean defectors (NKD), one of the representative groups of refugees. Additionally, evidence also suggests that females, who account for 70% of NKDs entering South Korea, are vulnerable not only to past trauma but also to the current acculturation stress and loneliness affected by neighborhood social cohesion. This study explores whether the mediating effect of loneliness on the relationship between acculturation stress and PTG was moderated by the neighborhood social cohesion among female NKDs. In this study, the data of 166 female NKDs who completed an online survey regarding acculturation stress, PTG, loneliness, and neighborhood social cohesion were used. Moderated mediation analysis was conducted using SPSS PROCESS macro program. Loneliness was associated with PTG (B = - 1.896, p < 0.001), and mediated the association between acculturation stress and PTG (indirect effect = - 0.278, 95% LLCI - 0.403, 95% ULCI - 0.166). Neighborhood social cohesion moderated the mediation effect of loneliness on the association between acculturation stress and PTG (B = - 0.016, 95% LLCI 0.001, 95% ULCI 0.035). The indirect effect of acculturation stress on PTG through loneliness was notably high for those with low neighborhood social cohesion. Therefore, increasing neighborhood social cohesion would reduce loneliness caused by acculturation stress and support the positive growth among female NKDs. This represents the most effective approach to aiding female NKDs in achieving growth, even after suffering trauma.

RESUMEN

BACKGROUND: This study aimed to investigate the prevalence rate of hepatitis C virus (HCV) infection and identify the demographic, and sociological characteristics and changes in awareness of HCV infection by participating the study for North Korean defectors residing in South Korea. METHODS: This study prospectively enrolled participants. Demographic, sociological and clinical data, and questionnaire surveys focused on awareness of HCV infection were collected. RESULTS: In total, 211 North Korean defectors participated in this study from September 2020 until June 2021. There were 174 women (82.5%), and the overall mean age was 48.9 years (range, 20 to 80 years). Of these participants, 112 (53.1%) had immigrated to South Korea since 2011. The overall prevalence of anti-HCV antibody among North Korean defectors was 1.9%. Thirty participants (14.2%) had hepatitis B surface antigens. A huge lack of awareness regarding HCV infection has been observed among North Korean defectors. CONCLUSION: This is the first prospective study to investigate the prevalence rate of HCV infection among North Korean defectors residing in South Korea. As North Korean defectors are a vulnerable group concerning HCV infection, they may benefit from HCV screening policies and educational interventions for HCV infection.

RESUMEN

BACKGROUND: This longitudinal study examined risk factors for future suicidality among North Korean defectors (NKDs) living in South Korea. METHODS: The subjects were 300 NKDs registered with a regional adaptation center (the Hana Center) in South Korea. Face-to-face interviews were conducted using the North Korean version of the World Health Organization's Composite International Diagnostic Interview to diagnose mental disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Subjects were also asked about sociodemographic and clinical factors at baseline. At follow-up after three years, the NKDs (n = 172 respondents) were asked to participate in an online survey, responding to self-questionnaires about suicidality. Logistic regression analyses were used to explore associations between baseline variables and future suicidality among NKDs. RESULTS: Thirty (17.4%) of the 172 survey respondents reported suicidality at follow-up. The presence of health problems over the past year, any prior suicidality at baseline, a higher score on a trauma-related scale, and a lower score on a resilience scale at baseline were associated with greater odds of suicidality at follow-up after adjusting for age, sex, and educational level. Of all mental disorder categories, major depressive disorder, dysthymia, agoraphobia, and social phobia were also associated with significantly increased odds of suicidality at follow-up after adjusting for age, sex, educational level, and prior suicidality at baseline. CONCLUSION: Resilience, a previous history of suicidality, and the presence of lifetime depressive disorder and anxiety disorder should be given consideration in mental health support and suicide prevention in NKDs.

RESUMEN

OBJECTIVES: Details regarding the management of COVID-19 in North Korea are unknown. The aim of this paper was to analyse media programmes in North Korea in order to understand public health measures and policies concerning COVID-19. SETTING: State-run news agency in North Korea. PRIMARY AND SECONDARY OUTCOME MEASURES: The classification of television programmes on COVID-19 broadcast in a state-run news agency, from January 2020 to May 2022, and public health measures introduced in the programmes. RESULTS: A total of 2671 programmes concerning COVID-19 were included in the study. These programmes provided detailed clinical guidelines to laypeople without medical expertise, including instructions for the usage of medication and preventive measures. An association between the media concern regarding COVID-19 and trade volume, as a proxy of border closure according to the concern of the authorities, provided hints to understand the priorities and aims of the authorities. CONCLUSIONS: The research outcomes provided significant insights into the effort to understand an impaired healthcare system and prevalent drug abuse behaviours in North Korea. Findings from further studies on the recently collected data might suggest additional implications on the North Korean policies on COVID-19.

RESUMEN

BACKGROUND: Effective health interventions for North Korean refugees vulnerable to metabolic disorders are currently unelucidated. OBJECTIVE: This study aimed to evaluate the effects of digital health interventions in North Korean refugees using a wearable activity tracker (Fitbit device). METHODS: We conducted a prospective, randomized, open-label study on North Korean refugees aged 19-59 years between June 2020 and October 2021 with a 12-week follow-up period. The participants were randomly assigned to either an intervention group or a control group in a 1:1 ratio. The intervention group received individualized health counseling based on Fitbit data every 4 weeks, whereas the control group wore the Fitbit device but did not receive individualized counseling. The primary and secondary outcomes were the change in the mean daily step count and changes in the metabolic parameters, respectively. RESULTS: The trial was completed by 52 North Korean refugees, of whom 27 and 25 were in the intervention and control groups, respectively. The mean age was 43 (SD 10) years, and 41 (78.8%) participants were women. Most participants (44/52, 95.7%) had a low socioeconomic status. After the intervention, the daily step count in the intervention group increased, whereas that in the control group decreased. However, there were no significant differences between the 2 groups (+83 and -521 steps in the intervention and control groups, respectively; P=.500). The effects of the intervention were more prominent in the participants with a lower-than-average daily step count at baseline (<11,667 steps/day). After the 12-week study period, 85.7% (12/14) and 46.7% (7/15) of the participants in the intervention and control groups, respectively, had an increased daily step count (P=.05). The intervention prevented the worsening of the metabolic parameters, including BMI, waist circumference, fasting blood glucose level, and glycated hemoglobin level, during the study period. CONCLUSIONS: The wearable device-based physical activity intervention did not significantly increase the average daily step count in the North Korean refugees in this study. However, the intervention was effective among the North Korean refugees with a lower-than-average daily step count; therefore, a large-scale, long-term study of this intervention type in an underserved population is warranted.

RESUMEN

THE AIM OF THE STUDY: Compare the properties of different dental implants depending on the design, shape and surface area in the experiment. MATERIALS AND METHODS: Dental implants with similar sizes (5.5×10 mm) were selected: Vitaplant VPKS, Mega Gen AnyRidge and Alpha Dent Superior Active. The calculation of the total area of the implants was performed and the implants were immersed in a ferromagnetic substance. RESULTS AND DISCUSSION: The small number of turns and their small length of the Vitaplant implant cannot create a large surface area (this size of the implant has an area of 174.7 mm2). On the thin, slightly conical body of the MegaGen implant (North Korea), the developer placed 10 turns of thread with wide blades. Due to the data design features, this implant has the largest surface area (276.5 mm2), which is an advantage in implant integration. The same number of turns (10) and a very similar frequency bring Alpha Dent implants (Germany) closer to the implant described above, but the design implements an innovative anti-rotation system. This implant size has a total surface area of 210.5 mm2. CONCLUSIONS: The implant Vitaplant VPKS is inferior in efficiency of the geometry of the implant Mega Gen AnyRidge by 24%, and the implant Alpha Dent Superior Active in turn ahead of the efficiency of the representative of the Korean company by 8.9%. The shape of the geometry of the implant affects the effectiveness of counteracting the masticatory load more than its surface area.

RESUMEN

OBJECTIVES: North Korean Refugees (NKRs) undergo defection, and this has been shown to impact their current health status in South Korea. However, little is understood about how the defection process is related to metabolic syndrome (MetS). This study regarded the defection process to be a quasi-measurement of traumatic experience and investigated whether defection was a risk factor for MetS among NKRs living in South Korea. STUDY DESIGN: This cross-sectional study obtained data from the Korea University Anam Hospital in Seoul. NKRs (N = 847) voluntarily completed questionnaires and underwent at least one medical examination between October 2008 and July 2021. METHODS: Multivariable logistic regression models were used to evaluate whether the number of countries transited by NKRs was associated with MetS by controlling for covariates. RESULTS: The prevalence of MetS among male and female NKRs in South Korea was 12.3% and 13.3%, respectively. The highest prevalence of MetS (33.4%) was among NKRs who had transited two countries. The number of months in transit countries (mean: 49.9 ± 51.7) and period of residence in South Korea (mean: 40.9 ± 40.9 months) were also considered. NKRs who transited three countries had a higher probability of MetS (odds ratio [OR] 2.660, 95% confidence interval [CI] 1.161-6.097) than those who travelled directly to South Korea. NKRs who transited three countries and had only resided in South Korea for a short period had a higher probability of MetS (OR 3.424, 95% CI 1.149-10.208) than those who have lived in South Korea for a longer period. CONCLUSIONS: Considering the social vulnerability of NKRs and consequential health problems, there is an urgent need for appropriate support from the government and society.

RESUMEN

The psychological impact of indirect trauma is unknown among North Korean (NK) refugees. We aimed to investigate the effects of direct and indirect trauma on the mental health of NK refugees in South Korea and evaluate the potential moderating effect of acculturative stress in this association. Using respondent-driven sampling, we recruited 323 NK refugees for this retrospective study. We measured exposure to direct and indirect trauma as independent variables, and posttraumatic stress symptoms (PTSS) and symptoms of depression and anxiety as dependent variables. After implementing multivariate imputation using chained equations, the associations between trauma type and psychological outcomes were assessed using ordinary least squares regression analyses, controlling for demographic covariates; the potential effect modification of acculturative stress was studied by adding an interaction term to the analyses. PTSS and symptoms of depression and anxiety were significantly associated with exposure to both direct, Bs = 0.24, 0.16, 0.19, respectively, p < .001s, and indirect trauma, Bs = 0.13, 0.08, 0.07, respectively, ps < .001. Although we did not observe significant effect modification, the magnitude of association between indirect trauma and PTSS significantly differed between the high, B = 0.18, p < .001, and low acculturative stress groups, B = 0.08, p = .024. These findings suggest that indirect trauma is associated with a more severe mental health consequence among NK refugees who experience high acculturative stress. Efforts to mitigate acculturative stress may reduce the mental health consequences of indirect trauma exposure.

RESUMEN

We isolated a new orthonairovirus from Dermacentor silvarum ticks near the China-North Korea border. Phylogenetic analysis showed 71.9%-73.0% nucleic acid identity to the recently discovered Songling orthonairovirus, which causes febrile illness in humans. We recommend enhanced surveillance for infection by this new virus among humans and livestock.

RESUMEN

PURPOSE: This study aimed to investigate the quality of medical care in North Korea using data from North Korean medical research. MATERIALS AND METHODS: This study included publications containing the keyword "medical" among North Korea's consecutive publications and selected 415 papers related to heart disease, brain disease, and emergency medical care published at The North Korean Data Center of the Ministry of Unification (https://unibook.unikorea.go.kr). Among 40 research articles, we reviewed ten with representative epidemiological data for cardiovascular treatment, and the latest medical materials were selected and analyzed in detail. RESULTS: Few studies reported the experience of large-scale medical facilities or verified professional performance. Proof of the efficacy of the latest drugs was rare, although the treatment results of interventional therapy and conventional heart surgery were reported. Efforts to improve emergency medical care and innovation of treatment materials using new technologies were being actively studied. However, careful interpretation is required due to the lack of objectivity in research data and some deviation in the composition of patients included in the data. CONCLUSION: Research of cardiovascular disease in North Korea is conducted at a very limited scope, although treatment results appear to be recorded. The management of cardiovascular disease and the establishment of an emergency medical system warrant global attention and cooperation for further improvement.

RESUMEN

North Korean (NK) refugee women report a disproportionately high rate of suicide compared to the general South Korean (SK) population. NK refugee women's exposure to gender-based violence (GBV) is a risk factor for adverse mental health symptoms. However, the association between GBV exposure and mental health has received less scholarly attention. This study examined NK refugee women's exposure to GBV (i.e., sexual violence, human trafficking, and forced sex work) and explored whether it is associated with an increased risk of depression, alcohol misuse, and suicide attempts. A three-way interaction between depression, alcohol misuse, and suicide attempts among GBV-exposed NK refugee women was examined. Data from a snowball sample of 180NK refugee women were analyzed for this study. Findings show that 47.8% experienced GBV in either NK or intermediary countries. Multivariate analyses revealed that depression (OR = 1.13, p < .05) and alcohol misuse (OR = 3.01, p < .01) was significantly associated with suicide attempts in GBV-exposed groups. Results from the three-way interaction (GBV victimization × Depression × Alcohol misuse) suggest that GBV exposure and higher levels of depression were significantly associated with suicide attempts among NK refugee women with greater severity of alcohol misuse (OR = 1.75, p < .05). The findings indicate that NK refugee women with GBV exposure, depression, and alcohol misuse are at increased risk for suicide attempts. Study limitations included the use of snowball sampling and cross-sectional data. This study discusses implications for future research and targeted, trauma-informed treatments focused on GBV and mental health symptoms among NK refugee women.
