Introduction. Earlier studies of low-dose fibrin monomer (FM) demonstrated that low-dose FM has unique hemostatic properties in vivo.

Aim — to compare the morphological consequences of intravenous administration of tranexamic acid (TXA) and FM with the hemostatic and hemostasiological effects in hypofibrinogenemia caused by the use of streptokinase after controlled liver injury.

Materials and methods. The morphological pattern of fibrin formation in the liver injury area after spontaneous arrest of bleeding in the animals treated with streptokinase or placebo was studied in 73 male rabbits of the Chinchilla breed, split into four groups. In three groups, the study was performed under the conditions of intravenous administration of placebo, TXA, or FM against the background of fibrinolysis activation by streptokinase. Platelet count in the blood, the concentration of fibrinogen, as well as the results of calibrated thrombography, were taken into account.

Results. Sequential administration of streptokinase and TXA was accompanied by decreased fibrinogen concentration (by 29.6 %) and, at the same time, a reduction in blood loss (by 15.4 times) in comparison with animals where placebo was used instead of TXA. A decrease in blood loss was associated with increased thickness of thrombotic deposits at the edge of the wound, mainly consisting of red blood cells. These observations were combined with data on the acceleration of thrombin formation in venous blood plasma in a calibrated thrombography test (Peak thrombin 65.4 nmol/L to 109.6 nmol/L in the placebo group). Compared to the observations where placebo was administered instead of FM, however, the sequential use of streptokinase and FM also led to a decrease in blood loss (by 11.0 times) despite decreased fibrinogen concentration (by 23.3 %). A decrease in blood loss was also associated with platelet consumption in venous blood and with increased thickness of thrombotic deposits on the injury surface, where, in addition to red blood cells, the accumulation of fibrin masses was determined by the morphological pattern.

Conclusion. The mechanisms of the systemic hemostatic effect of TXA and FM are different, despite the similarity of the achieved hemostatic effects in the conditions of stimulation of blood fibrinolytic activity. These findings expand the understanding of new therapeutic possibilities for reducing post-traumatic blood loss.
The characterization and frequency of diagnosis of EBV-positive variants with a lymphoid predominance in the structure of Hodgkin lymphoma
Authors: Shupletsova I. A. , Kovrigina A. M.
Published: December 2021

Introduction. Epstein — Barr virus (EBV) plays an important role in the pathogenesis of lymphoid tumors, in particular Hodgkin lymphoma. The frequency of expression of the EBV varies in different histological variants of classical Hodgkin lymphoma and is rarely observed in nodular lymphocyte predominant Hodgkin lymphoma.

Aim — to study the pathomorphological features of the histological variants of Hodgkin lymphoma with lymphoid predominance associated with the EBV, as well as the frequency of their diagnosis in the structure of Hodgkin lymphoma.

Materials and methods. The retrospective study included 794 patients with a verified diagnosis of Hodgkin lymphoma using histological and immunohistochemical methods on biopsy material for the period 2018–2019 (age range — 18–91 years old; median — 34 years old; men : women — 1.1 : 1). The presence of EBV in biopsies was assessed by immunohistochemical reaction with antibodies to EBV (clone LMP1), or by chromogenic in situ hybridization with probes for EBV-encoded small RNAs.

Results. Classical Hodgkin lymphoma was diagnosed in 91 % (725/794) cases, nodular lymphocyte predominant Hodgkin lymphoma — in 9 % (69/794) cases. EBV-positive Hodgkin lymphoma accounted for 11 % (82/725) of all cases of classical Hodgkin lymphoma, (age range — 18–81 years old, median — 45 years old; men : women — 2.5 : 1). All cases of nodular lymphocyte predominant Hodgkin lymphoma were EBV-negative. Lymphocyte-rich classical Hodgkin lymphoma was found in 14 patients (14/725, 2 %), 4 patients showed intermediate morphoimmunohistochemical features with nodular lymphocyte predominant Hodgkin lymphoma, which were statistically significantly different from classical Hodgkin lymphoma by the presence of B-zones in the form of large nodules (p = 0.0157) and expression CD20 by tumor cells (p = 0.0404).

Conclusion. Nodular lymphocyte predominant Hodgkin lymphoma is not characterized by a connection with EBV infection, unlike classical variant — lymphocyte-rich classical Hodgkin lymphoma. The obtained data support the concept of the existence of a transient form of Hodgkin lymphoma, which has the features of nodular lymphocyte predominant Hodgkin lymphoma and classical Hodgkin lymphoma, in the pathogenesis of which the Epstein — Barr virus likely plays a role.
Clonal hematopoiesis and its role in the development of hematological diseases
Authors: Petinati N. A. , Drize N. J.
Published: December 2021

Introduction. The formation of blood cells in a healthy individual is ensured by polyclonal hematopoiesis. Recent studies have shown that with age, large clones with a common genetic marker are found in the peripheral blood, i. e. cells originating from a single progenitor cell. This phenomenon is called clonal hematopoiesis. In some cases, people with clonal hematopoiesis develop hematological diseases.

Aim — to describe and summarize current data on the relationship between clonal hematopoiesis and hematological diseases.

Main findings. This review describes the history of detection of clonal hematopoiesis, its main properties, the most frequent mutations in hematopoietic clones associated with the risk of transformation into myelodysplastic syndrome, and acute myeloid leukemia. The meaning and possible pathogenesis of tumor transformation are discussed.

Published: December 2021

A criterion of the quality of fresh frozen blood plasma (FFP) is the activity of clotting factor VIII (FVIII).

Aim — to identify technological barriers in the study of FVIII thermolability and to describe the requirements for experiments, providing new knowledge about the thermolability of this factor.

Basic information. An analysis of domestic and foreign publications devoted to the study of the mechanisms responsible for reducing the value of FVIII activity in donor blood plasma from the moment of donation to the moment of transfusion was carried out. Data on the decrease in FVIII activity at various stages of work with blood plasma are presented. An analysis of methods for preparing samples for studying changes in the values of FVIII in donor blood plasma was performed. The existence of contradictory conclusions about the infl uence on the change in FVIII at the thawing stage of various values of the effects on FFP and poor knowledge of the change in the indicator at the stage of heating to the transfusion temperature after the end of the phase transition in the samples was established. The fundamental differences in the methods of preparing and conducting experiments in previous works are determined. Methods for increasing the reliability of experimental results for studying the thermal lability of FVIII are proposed.
Women in Culture. Introduction to the Issue
Authors: Duda Krzysztof , Troitskiy Sergey
Published: December 2021

The late 1960s and early 1970s development of liberation discourses (postcolonial, racial, ethnic, gender, environmental, etc.) resulted in them turning not only and not so much into an intellectual strategy, but instead, in their entering culture as social practices, and becoming the main patterns of behavior and models of thinking. 1 In this context, the feminist discourse, 2 which initially developed as a political and legal narrative of the struggle for women’s rights, unfortunately became a world view and even an ideological discourse of opposition and competition between the sexes as it spread. In view of the above, the current cultural situation pursued by feminist activists in terms of gender can be described as a struggle for alpha leadership between an antagonist and a protagonist in the course of a liberation discourse (Gaag, 2014; Carrigan, Connell & Lee, 1985, pp. 551–604; Wood, 2011). Such a struggle is also often described in the terminology of Darwinian natural selection and, therefore, it is realized in social practices as an all-out war between the “oppressors” and the “oppressed,” justified by the criteria of biological (non)utility in nature or society.
Typologia męskiego i kobiecego portretu miniaturowego w elżbietańskiej Anglii
Authors: Troitskaya Anna
Published: December 2021

Artykuł zawiera analizę szczegółowych, semantycznych i kompozycyjnych cech miniaturowych angielskich portretów tworzonych w XVI w. Większość z tych dzieł wykazuje się stylistyczną jednolitością, ścisłym przestrzeganiem przez autorów formalnych zasad artystycznych. Porównanie wykazało jednak, iż pomimo ogólnego podobieństwa, wynikającego z ustalonej tradycji i praktyki, wyraźnie są widoczne też różnice w stylistycznym i kompozycyjnym podejściu do portretu. Opierając się na opisie wyjątkowego procesu tworzenia miniatury pozostawionym przez elżbietańskiego artystę N. Hilliarda, można zauważyć techniczne różnice w tworzeniu męskich i kobiecych obrazów. Przytoczone w artykule przykłady wskazują na możliwość zbadania angielskiej miniatury portretowej i jej typologii z pozycji „męskie – kobiece”. Charakterystyczne wyróżniające cechy przejawiają się nie tylko w rysunku i kolorystyce, ale także w stopniu indywidualizacji obrazu portretowego. Program portretu męskiego jest bardziej zróżnicowany semantycznie i świadczy o rosnącym zainteresowaniu indywidualnością u zarania nowożytności.
Feminist Mining: A Step Towards Sustainable Mininig in India
Authors: Singh Priya , Behura Ajit Kumar
Published: December 2021

Economic growth and development with least harm to the environment is one of the biggest challenges for the human. Mining which is considered to be the most inherently unsustainable industry, is at the same time, plays key role in the development process in India and across Globe. It occupy primary position in the supply chain, contributing to the foreign direct investment, exports, government taxes, GDP (National Income) and provide huge labour employment.
This paper studies industrial elimination of women, prolong industrial patriarchy, impetuous production, rising demand pressure has added to the quadrupling problems of land degradation, disposal of over burden/waste discharge, deforestation, pollution(air, water, and noise), and damage to forest flora and fauna, occupational health hazards and extreme global environmental damage in a rapid, continuous manner. These continuous and multi-layered problems are giving us reason to re-visioning steps, where we went wrong.
Theoretical foundation of eco-feminism traces that negligence and suppression of women in general and in the mining industry, is one of the probable cause that hit environment fiercely. With this in mind, this paper suggests theory of eco-feminism into male centric mining industry as a perspective which is more likely to lead to industrial sustainability, making it more responsible and may provide pro-environmental solutions to the industry. This feminist concept extending it from individualistic level into mining organisations proposes as one of the alternative to combine ecology and commerce to envision sustainability.
Financial Development and Sustainable Competitiveness in Arctic Region: A Dynamic Panel Data Analysis
Authors: Yahya Farzan , Abbas Ghulam , Hussain Muhammad , Waqas Muhammad
Published: December 2021

The present study investigates the effect of financial development on sustainable competitiveness and its components (natural capital, resource intensity, and social cohesion) in the Arctic region. We employ bank-based, stock-market based, and composite index to measure financial development. To deal with endogeneity bias, system GMM is utilized. The results show a positive and significant effect of financial development on sustainable competitiveness. The estimates also assert that financial development encourages resource efficiency and social cohesion in the region. In contrast, we find the negative effect of financial development on natural capital. This suggests that overexploitation of natural resources may provide short-term benefits to the local and regional communities but it may threaten the long-term sustainability of the Arctic. Thus, the financial sector should be guided to support financing and investing activities in alternative eco-friendly technologies and ventures for reducing excessive natural resource utilization.

Authors: Tazikhina Tatiana , Kvasha Vladimir , Solovova Yulia , Guliev Igbal
Published: December 2021

The green energy agenda has become one of the most important issues in international relations. Many island states of the Oceania have taken the course of green economy construction. The Caribbean states are in some way similar to the Oceania ones and have also made several steps towards greener future. Some of these states are tightly connected with international tourism, leading to the high dependence of their economies from touristic revenues. The article examines this interconnection, including economic component in the analysis. The major question of the article is how does (or doesn’t) tourism influence the development of green energy in the Caribbean states. The two major economies examined in the region are Cuba and Dominican Republic as the two examples of the totally different economic systems and approaches to the development of the green energy. The key findings of the article include such conclusions as the possibility of synergetic  interdependence between tourism, economy and green energy and the positive effects this interdependence has. The other finding is that the Cuban method of introducing green energy is less effective than the Dominican one. The novelty of the article includes the comparison of the two economic models in the Caribbean and the development of strategies for the green energy proliferation in the countries.
Samkhya Philosophy, Deep Ecology and Sustainable Development
Authors: Biswas Nanda Gopal , Prakash Gyan
Published: December 2021

Samkhya philosophy is one of the oldest philosophies in the Indian philosophical system. This philosophy is independent in origin and mainly known for its evolution theory.  Samkhya philosophy has accepted the two ultimate and independent realities, Nature and pure Consciousness. This paper is an attempt to comprehend the notion of deep ecology from the Samkhya’s evolution theory perspective. In this paper, firstly, we have elucidated the Samkhya philosophy of suffering and the solution to the problem. In the second part of the article, we have argued that how Samkhya’s philosophical notion of Nature demonstrates our embeddedness in Nature.  Therefore, the idea of deep ecology is always there in one or another form in Samkhya philosophy. It has also connections to the idea of sustainable development.
Observation of frequency dependent resonances in magnetic vortex core gyration using time-resolved magneto-optical Kerr microscope with pulsed semiconductor laser illumination
Authors: Ogasawara Takeshi , Yamaguchi Akinobu
Published: December 2021

Frequency dependent resonance of magnetic vortex core gyration in micrometer sized permalloy squares was observed by time-resolved magneto-optical Kerr microscope using pulsed semiconductor lasers as a light source in the stroboscopic method. Uniform and efficient laser illumination was realized by a speckle reducer consisting of an oscillating multimode optical fiber and a microbending mode scrambler. The resonance frequency of the same sized permalloy squares showed a non-uniformity of up to 15%, suggesting the flatness of the underlayer has a strong influence on the gyration motion.
Formulation of trade-off relationships between resolution, line edge roughness, and sensitivity in sub-10 nm half-pitch region for chemically amplified extreme ultraviolet resists
Authors: Kozawa Takahiro
Published: December 2021

The manufacturing of semiconductor devices using extreme ultraviolet (EUV) lithography started in 2019. A high numerical aperture tool under development is capable of resolving 8 nm line-and-space optical images and will extend the application of EUV lithography. However, resist materials have not been yet applicable to the production with 8 nm resolution. In this study, the relationships among the half-pitch of line-and-space patterns (resolution), chemical gradient [an indicator of line edge roughness (LER)], and sensitivity were investigated in the sub-10 nm half-pitch region for chemically amplified EUV resists. The chemical gradient was simulated on the basis of their sensitization and reaction mechanisms. The relationship was formulated as a function of total sensitizer concentration (the sum of photoacid generator and photodecomposable quencher concentrations) and the thermalization distance of secondary electrons. The effect of thermalized electrons was well incorporated into the trade-off relationships between resolution, LER, and sensitivity. (147/150)

Directly measuring thermal focal length is important for designing and optimizing the mode-locking oscillator, especially for a 2 μm mode-locking laser. In this paper, we propose a novel interferometric method for measuring the thermal focal length in a 2 μm mode-locking laser. This method provides a precise measurement of the thermal focal length inside a long-folded oscillator in both lasing and non-lasing operation. We also theoretically calculate the thermal focal length based on the temperature distribution inside the laser crystal, which matches well with the experimental results.

Additive Mixed Sensitivity Design of PID Controllers for Continuous-Time System with Uncertain Time-Delay
Authors: Emami Tooran
Published: December 2021

This paper presents an algorithm for all achievable coefficients of Proportional Integral Derivative (PID) controllers in an integral-derivative plane that stabilizes and satisfies additive mixed sensitivity constraint with an uncertain time delay for a continuous-time system. This algorithm solves the singularity problem of designing PID controllers in the integral and derivative plane and estimates achievable ranges of proportional gain of the PID controllers. A numerical cascaded ball and beam with unity feedback control of an SRV-DC motor and uncertain communication time delays in the system process demonstrate the application of this methodology. In this application, the additive weight bounds the additive errors for the cascaded ball and beam and the closed-loop SRV-DC motor system transfer function with the internal communication time delays
Estereotipos de género en educación física y deporte en Mozambique.
Authors: José Paticene Sandra , Muros Ruiz Beatriz , López de la Varga Sergio
Published: December 2021

Resumen: El presente estudio trata de arrojar luz sobre la construcción y perpetuación del estereotipo sexual de género ligado a la educación física y el deporte en Mozambique. El diseño de estudio obedece a una metodología de investigación fenomenológica. Las participantes fueron mujeres relacionadas con diferentes ámbitos educativos así como mujeres vinculadas con medios de comunicación deportivos y que pudieran aportar información sobre la problemática social del estereotipo de género en Mozambique. Los resultados resaltan que los estereotipos de género se manifiestan en la educación física y en el deporte, desde la prohibición del uso de pantalones cortos en las clases, las desigualdades de sueldos en los equipos deportivos, la no visibilización del deporte femenino en los medios de comunicación social. El estudio indica que se sigue la tendencia a perpetuar estereotipos patriarcales en la educación física y el deporte. Los cambios propuestos por tanto, deben ser más profundos que acciones aisladas, y que atañen a estructuras sociales que intervengan en la ideología preconcebida sobre la mujer.

Polarity in cuticular ridge development and insect attachment on leaf surfaces of Schismatoglottis calyptrata (Araceae)
Authors: Surapaneni Venkata A , Aust Tobias , Speck Thomas , Thielen Marc
Published: December 2021

The plant cuticle is a multifunctional barrier that separates the organs of the plant from the surrounding environment. Cuticular ridges are microscale wrinkle-like cuticular protrusions that occur on many flower and leaf surfaces. These microscopic ridges can help against pest insects by reducing the frictional forces experienced when they walk on the leaves and might also provide mechanical stability to the growing plant organs. Here, we have studied the development of cuticular ridges on adaxial leaf surfaces of the tropical Araceae Schismatoglottis calyptrata. We used polymer replicas of adaxial leaf surfaces at various ontogenetic stages to study the morphological changes occurring on the leaf surfaces. We characterized the replica surfaces by using confocal laser scanning microscopy and commercial surface analysis software. The development of cuticular ridges is polar and the ridge progression occurs basipetally with a specific inclination to the midrib on Schismatoglottis calyptrata leaves. Using Colorado potato beetles as model species, we performed traction experiments on freshly unrolled and adult leaves and found low walking frictional forces of insects on both of these surfaces. The changes in the micro- and macroscale morphology of the leaves should improve our understanding of the way that plants defend themselves against insect herbivores.
The Columbus Linguistics in High School experience: Fits and starts as a prelude to success
Authors: Paxton Victora , Dickerson Carly , Joseph Brian D.
Published: December 2021

We report here on our efforts to incorporate linguistics into the high school curriculum in a large midwestern metropolitan area through a university-based initiative — Linguistics in High School (LxHS) — spearheaded by the Department of Linguistics at The Ohio State University. We offer a brief history of the project, and explain our strategy of targeting non-public schools and the practical nature of the reasoning behind this decision. We chronicle the ups and downs of our efforts, ultimately reporting on our success with implementing a linguistics course and a linguistics club at a small local STEM-oriented high school. This partnership between the school and the Linguistics Department has allowed, among other things, for on-site visits by the students to phonetics and sociolinguistics labs. By presenting our challenges, strategies, failures, and successes, we hope that others may be encouraged to evaluate how they can make a difference in their locale and with the resources they have.
Contracting Forensic DNA Experts by the Defense in Hungarian Criminal Procedure
Authors: Nogel Mónika
Published: December 2021

Most of the studies published in Hungary on the judicial expert system and expert evidence in criminal proceedings do not deal with the question whether the availability of forensic DNA experts is adequate for the defense. This paper examines the current legal environment and focuses on this question. The study also gives a brief overview of the circumstances when DNA analysis plays an essential role in criminal cases. Finally, the article will show whether the defense can employ its own forensic DNA expert in criminal cases.
Tropicalismo cañí: expresiones de una nueva españolidad postmoderna en la música urbana actual
Authors: MARTÍNEZ-SÁEZ CELIA
Published: December 2021

Este artículo analiza nuevas expresiones de ‘españolidad’ originadas en productos audiovisuales de la escena de la música urbana actual. Analizando ejemplos de artistas como C. Tangana, Rosalía y Califato ¾ exploro cómo estos artistas emplean el imaginario de lo castizo para descentralizar Castilla como mito dominador geopolítico del Estadonación español. La orientalización de lo ‘español’, junto a símbolos como el flamenco, el toreo, las mantillas negras, la imaginaría católica y el discurso del subdesarrollo español aparecen resignificados con símbolos asociados con la cultura latinoamericana, guiños feministas y/o mezcla de géneros musicales como el trap, la bachata, o el rock argentino. A través del análisis de algunos productos audiovisuales, este artículo analiza la resignificación de símbolos asociados a la ‘españolidad’ a través del concepto de ‘zonas de contacto’ de Mary Louise Pratt (‘Arts of the Contact Zone’, 1991) en el que la cultura castiza se convierte en una suerte de espacio rizomático para la negociación de símbolos anacrónicos franquistas asociados con lo ‘castizo’ con un presente globalizado, imperativamente latinoamericano por las exigencias del mercado de la música urbana actual.
Nonperiodic Type I Be/X-Ray Binary Outbursts
Authors: Martin Rebecca G. , Franchini Alessia
Published: December 2021

Type I Be/X-ray binary outbursts are driven by mass transfer from a Be star decretion disk to a neutron star companion during each orbital period. Treiber et al. recently observed nonperiodic type I outbursts in RX J0529.8–6556 that has unknown binary orbital properties. We show that nonperiodic type I outbursts may be temporarily driven in a low eccentricity binary with a disk that is inclined sufficiently to be mildly unstable to Kozai–Lidov oscillations. The inclined disk becomes eccentric and material is transferred to the neutron star at up to three locations in each orbit: when the neutron star passes the disk apastron or one of the two nodes of the disk. The timing and magnitude of each vary with the disk argument of periapsis and longitude of the ascending node that precess in opposite directions. Calculating the orbital period of the RX J0529.8–6556 system is nontrivial but we suggest it may be >300 days, longer than previous estimates.

BACKGROUND: Studies in psychology often discuss adolescents with their strong self-esteem as individuals who know themselves. Self-esteem development in adolescents. These adolescents begin to understand the changes of personality development starting from the cognitive aspect or thoughts, emotion, feeling, social, and physical aspects.

AIM: This study consistently aimed at finding comprehensive evidence that positive parenting and friendship affect self-esteem in adolescents.

METHODS: The population of this study was adolescents, namely 173 senior high school students consisting of 72 males and 100 females who were involved and participated in this study. The data analysis, in this study, was the 2 predictors for linear regression analysis.

RESULTS: The results showed that parenting and friendship simultaneously influenced self-esteem formation in adolescents. Partially, the result of this study also showed that parenting affected self-esteem formation in adolescents.

CONCLUSION: In conclusion, friendship showed a significant effect on self-esteem formation in adolescents. Thus, the hypotheses in this study were accepted.

Published: December 2021

AIM: The aim of the study was to evaluate effect of silver diamine fluoride (SDF) on the shear bond strength (SBS) of glass ionomer restoration to primary dentine. MATERIALS AND METHODS: Twenty extracted primary molars with no restorations or developmental anomalies were only chosen for the study. Twenty dentine slices with 2 mm thickness were prepared and then randomly allocated into two groups (n = 10 per group). For Group 1 (experimental): Dentine surfaces were treated with 38% *SDF solution (Elevate oral care, USA) for 3 min using micro-brush, followed by a 30 s rinse with water and Group 2 (Control): Dentine surfaces were treated with distilled water for 3 min then rinsed for 30 s. The cavity conditioner was applied to flat dentin of both groups for 10 s then washed and dried gently with compressed air. All the specimens were restored with *RMGIC (Riva Light Cure, SDI, Australia). SBS was determined using a Universal Testing machine and Failure mode was evaluated using stereomicroscope. Data were collected and statistically analyzed. Independent t test was used to assess differences in SBS between study groups and mode of failure was analyzed using Fisher’s exact test. Level of significance was set at p ≤ 0.05. IBM SPSS statistical software (version 26) was used to analyze the data. RESULTS: The experimental group had significantly higher mean of shear bond (11.92 ± 3.35) strength than the control group (6.99 ± 2.98) (p = 0.003). CONCLUSIONS: Primary dentin pre-treatment with 38% SDF increases the shear bond strength between RMGIC and primary dentin according to the results of this in vitro study.

Published: December 2021

BACKGROUND: Nurses play an essential role, including being the main educator of diabetes mellitus (DM). It is necessary to reduce the barriers faced by nurses in managing patients’ self-management.

AIM: The purpose of this study was to explore the barriers faced by nurses in managing the self-management of DM patients.

METHODS: This research is a qualitative-research with a phenomenological approach. The recruitment of participants used a purposive sampling method, which was divided into two Focus Group Discussion (FGD) groups: the first group consisted of five nurses from the urban health center and the second group consisted of five nurses from the suburban area. The FGD was conducted twice for each group: 90 min for the first and 45 min for the second. The data were analyzed using Colaizzi’s method of data analysis.

RESULTS: This study resulted in two themes, namely, internal barriers within the patient and external barriers outside the patient. The barriers from within the patient theme had five subthemes including (1) fear of being exposed to the disease and stigma associated with diabetes, (2) fear and distrust of health cadres, (3) low self-awareness and feeling healthy so not seeking treatment, (4) lack of responsibility for diabetes self-management practices, and (5) time issues. The second theme of barriers external to the patients included three subthemes that were (1) limited manpower, (2) limited facilities and funds, and (3) a lot of programs or activities.

CONCLUSION: Nurses faced external barriers that arise from the puskesmas and internal barriers within the patient.
