Cryptocurrency returns and volatility spillover during an era of uncertainty: COVID-19 and VIX
Authors: Bozma Gürkan , Sercemeli Murat , Çelik Ali Kemal
Published: January 2025

This study investigates the volatility of cryptocurrencies during the
uncertainty created by COVID-19 and the Chicago Board Options Exchange
Volatility Index (VIX). Hence, the relationship between cryptocurrencies in
the pre- and post-COVID-19 era was introduced into a mean equation that
applied the VAR (1)-BEKK GARCH-M (1,1) method to the eight largest market
volume cryptocurrencies. Descriptive statistics show the Dogecoin has the
most volatility, BNB has the highest return, and BTC has the lowest
volatility. Due to the lag in its return during the pre-COVID-19 time frame,
BTC harms other coins? returns. Other coins? returns, including their own,
are increased by the Dogecoin?s one-period lagged return. Notably, only BNB,
XLM, and XRP were statistically significantly impacted by VIX spikes. This
study highlights the fact that cryptocurrencies experience first-instance
(average) volatility. Bitcoin?s long-term uncertainties statistically
significantly and favorably enhance other cryptocurrencies? long-term
uncertainties.

Validation of the pipeline for the 1.4m Milankovic telescope
Authors: Lalovic A. , Vince O. , Stojanovic M. , Marceta-Mandic S.
Published: January 2025

In this paper, we present a pipeline written in Python v3.9 that performs
reduction of CCD images, astrometric calibration, and photometric
measurements for observations made with the 1.4m Milankovic telescope,
installed at the Astronomical Station Vidojevica in Serbia. The main driver
for writing such a multipurpose pipeline lies in its intended use once the
dedicated observations of transient objects with the Milankovic telescope
start as the follow-up observations contributing to the Vera Rubin
Observatory scientific goals, but not limited to this specific need, since
other follow-up observations had been conducted and some are still ongoing.
The pipeline is run via the command line using different positional and
optional arguments depending on the required operations (reduction,
astrometry, photometry). There are also command-line arguments that allow
the user to choose how to perform a certain operation (mode), or whether to
use more PC processors to execute them. By default, only bias, dark, and
at-field corrections are performed, while other operations and modes are
optional. In the paper, we will describe in detail each of the above
mentioned operations, as well as the use of positional/optional arguments.
We will also describe in detail the output FITS files that can be used to
analyze the pipeline performance, as well as the final output tables with
photometric measurements. Finally, we compare the pipeline performance with
IRAF package procedures to test and validate the results.

Published: January 2025

Vitamin D (calciferol), i.e. its active metabolite calcitriol [1,25(OH)2D],
apart from essential participation in calcium and phosphorus homeostasis,
is an important factor in the regulation of cell proliferation,
differentiation and apoptosis, angiogenesis, imine and hormonal activity and
others processes in the human body. Hence, its optimal balance is extremely
important for adequate prenatal and postnatal growth and development, as
well as for the preservation of health in other phases of life. This article
provides a brief overview of the natural source of vitamin D, its metabolism
and physiological role, as well as current recommendations related to the
coverage of its optimal needs.
Spontaneous air leak syndrome: A very rare pulmonary complication of an eating disorder
Authors: Djurovic Marija , Rancic Nemanja , Pantic Milica
Published: January 2025

Introduction. Eating disorders are characterized by persistent body
dissatisfaction and unhealthy weight control. Spontaneous air leak syndrome
(ALS) is a rare but potentially fatal complication of a perennial eating
disorder that can lead to malnutrition with hypoproteinemia. We present a
young male suffering from anorexia nervosa who developed a severe form of
spontaneous ALS. Case report. The 25-year-old male patient was initially
treated for problems with an eating disorder of the persistent anorexia
nervosa type. He deliberately lost about 40 kg during the previous four
years. During hospital treatment, the patient suddenly developed severe pain
in the abdomen, for which he was urgently referred to a surgeon. He was
admitted to the Intensive Care Unit exhausted and afebrile, with the
abdomen below the level of the chest and diffuse painful tender-ness, with
peristalsis audible and petechiae present on the skin of the back, arms, and
thoracic wall. Computed tomography of the thoracoabdominal region was
performed, which showed air in the mediastinum, in the spinal canal, around
the stomach, in the rectum, and in the small pelvis. After an emergency
laparotomy, a drainage of the abdominal cavity and intraoperative
esophagogastroduodenoscopy were performed. The patient developed
neurological complications postoperatively. After a successful recovery, he
was treated psychiatrically on an outpatient basis and monitored for
several months. Further similar complaints did not occur. Conclusion.
Patients with nutrition-al disorders should be closely monitored because a
significant protein deficit with spontaneous ALS can occur. Timely
diagnosis and treatment can prevent further somatic deterioration and save
the patient?s life.
1-year data on patient-reported outcome is enough after surgery for degenerative cervical myelopathy: a cohort study from the Swedish Spine register
Authors: Gerdhem Lovisa , MacDowall Anna , Gerdhem Paul
Published: January 2025

Background and purpose: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Repeated follow-ups after surgery are resource consuming. The aim was to examine whether patient-reported outcome measures (PROMs) change after the first year. The purpose of this study was to investigate whether it is necessary to obtain follow-up data from patients more than 1 year after surgery for DCM.Methods: We included individuals treated surgically for DCM in the Swedish Spine registry (Swespine), with available preoperative, 1-, and 2-year PROMs, primarily the European Myelopathy Scale (EMS) and secondarily the Neck Disability Index (NDI), and the European Quality of life Visual Analogue Scale (EQ-VAS). A tertiary analysis included available 5-year data. Median, interquartile range (IQR), and Bland–Altman plots were used to compare PROM data at different follow-up time points.Results: 642 individuals had baseline, 1-, and 2-year follow-up data, of whom 347 also had 5-year data. EMS was 14 (12–16) preoperative, 15 (12–17) at the 1-year follow-up, and 15 (12–17) at the 2-year follow-up. Corresponding data for NDI was 38 (24–50), 25 (12–42), and 26 (12–42) and for EQ-VAS 50 (30–60), 60 (42–77), and 60 (40–75). Similar findings were seen in individuals who also had 5-year data. Bland–Altman plots indicated good agreement between 1- and 2-year data, and between 1- and 5-year data and were without proportional bias.Conclusion: In individuals treated for DCM no clinically meaningful change in PROMs occurred after the 1-year follow-up.

Authors: Sirola Suvi-Maria , Heikkinen Juuso , Kerimaa Pekka , Kariniemi Juho , Niinimäki Tuukka
Published: January 2025

Background and purpose: Recurrent hemarthrosis (RH) is a rare late complication of knee arthroplasty, with an unknown etiology. We aimed to evaluate the effectiveness of arterial embolization (AE) on resolution of hemarthrosis following knee arthroplasty. Additionally, we investigated pain management requirements after the procedure and related complications.Methods: 56 patients underwent AE for recurrent hemarthrosis between 2015 and 2023. The prevalence of hemarthrosis was 0.6%. The median age of the patients was 70 years (range 42–88), with 41 females and 15 males. 70 embolizations were performed, consisting of 56 initial procedures and 14 repeat procedures. Clinical success was defined as the resolution of hemarthroses.Results: Technical success was achieved in 93% of cases. Clinical success improved from 64% to 79% after the second treatment; subsequent sessions did not yield further improvement. 12 patients (21%) required 1 or more reoperations. The majority of patients (86%) relied solely on analgesics for post-treatment pain management. Complications occurred in 7% of treatments, most of which resolved spontaneously.Conclusion: AE is effective in the treatment of recurrent hemarthrosis but 21% had reoccurance. Oral analgesics are generally sufficient for managing post-embolization pain. 7% had complications.
Hydroxychloroquine-induced Sweet’s Syndrome: A Case Report and Literature Review
Authors: Almeida-Silva Gustavo , Antunes Joana , Tribolet de Abreu Inês , Monteiro Filipe , Vasconcelos Pedro , Soares-Almeida Luís , Filipe Paulo
Published: January 2025

Sweet’s syndrome (or acute febrile dermatosis) is a neutrophilic dermatosis with a characteristic presentation encompassing specific clinical (fever and erythemato-violaceous oedematous papules, plaques and nodules), laboratory (neutrophilia and increased inflammatory markers), and histological (dermal neutrophilic infiltrate without vasculitis) features. Its pathophysiology is poorly understood but there seems to be an auto-inflammatory component related to mutations in inflammasome genes. It has been subdivided into its classic form, malignancy-associated, and drug-induced, according to its aetiology. The condition usually responds rapidly to steroid therapy, but recurrences are common. This report presents an extremely rare case of hydroxychloroquine-induced Sweet’s syndrome, plus a review of the literature, which encompasses 3 previous cases of Sweet’s syndrome induced by hydroxychloroquine and 1 induced by chloroquine. Despite being relatively easy to diagnose, aetiological investigation poses challenges to the clinician, especially in the elderly population, as several confounding factors might be present. Further studies are necessary to shed light on the pathophysiology behind this entity, to further facilitate diagnostic workup and treatment strategies.
The presence of unknown polio engagement confirmed by electromyography and muscle testing
Authors: Al-Najjar Waleed , Krabbe David , Strandberg Joakim , Sunnerhagen Katharina S.
Published: January 2025

Objective: To evaluate the usefulness of electromyography at a polio clinic in identifying unperceived muscle denervation. Second, to compare people who perceived themselves as weak in 1 or both legs with those who did not.
Design: Cross-sectional study.
Subjects: The study included 542 persons with late effects of polio in Sweden. Mean age 58 at the first visit, 312 were female. Data used are from a clinical quality registry.
Methods: At the first visit patients answered sent-out questionnaires. They underwent an electromyography test, walk test, and muscle strength assessment.
Results: Electromyography identified signs of chronic neurogenic changes in lower limb muscles (n = 260) where the patient reported no previous involvement, comprising 239 of the participants. Significant differences in values shows that the group who did not perceive themselves as weak exhibited better performance, demonstrating greater speed, strength, and reduced reliance on wheelchairs.
Conclusion: Electromyography can identify signs of muscle denervation in association with weakness in people with late effects of polio who perceived themselves as healthy. This comparison suggests that those that do not perceive weakness may unknowingly overuse their muscles. These findings contribute to our understanding of the late effects of polio and importance of early detection and rehabilitation.
Research on the mechanism of ultrasonic-assisted underwater laser wet welding of 304 stainless steel
Authors: Zhou Jia , Zeng Junjie , Zhou Liao , Jiao Hui , Huang Yuxing , Ouyang Li , Zhu Ruihu , Long Yuhong
Published: January 2025

The dynamic evolution of cavitation bubbles in underwater wet laser welding significantly influences the laser beam. To mitigate the adverse effects of cavitation bubbles, an ultrasonic-assisted underwater laser wet welding method is proposed. This work reports an experimental study of ultrasonic-assisted underwater laser welding 304 stainless steel at varying welding speeds, different water layer thicknesses, and different ultrasonic powers. Additionally, the high-speed photography method was used to analyze the effect of ultrasound on the movement of cavitation bubbles, and a ray optics finite element model was employed to better understand the impact of cavitation positions on the laser beam. The results indicate that, under identical process parameters, the application of ultrasonic waves controls the movement of cavitation bubbles via acoustic flow. Consequently, the weld seam is more uniform, and the width and depth are increased effectively. In addition, without ultrasonic assistance, the weld seam width and depth decrease with higher welding speeds and decrease with the increase of the water layer thickness. With ultrasonic assistance, the weld seam width decreases while the depth increases at higher welding speeds. The weld seam width and depth increase with the increase of ultrasonic power. The weld width first decreases and then increases as the water layer thickness increases, and the weld seam depth shows a decreasing trend. These indicate that the dynamic evolution of cavitation bubbles has an important impact on the weld width and depth. This study can provide a reference for achieving better weld efficiency and geometry in underwater laser wet welding.

Authors:   Universidad de Guayaquil, Guayas, Ecuador., Diaz Robles Miguel Eduardo
Published: January 2025

La investigación en el área minera de La Pangui aborda la problemática de la contaminación por metales pesados debido a las actividades mineras, lo que representa un grave riesgo tanto para el ecosistema local como para la salud pública. La presencia de metales como cadmio, mercurio, plomo y hierro en las escombreras supera los valores recomendados y está asociada con prácticas mineras inadecuadas y la falta de control ambiental. Para el estudio, se utilizó una metodología que incluyó el análisis químico de muestras de escombreras y un análisis petrográfico mediante microscopio de luz polarizada, evaluando las concentraciones de metales y comparándolas con otras áreas mineras similares, como Ponce Enríquez, para establecer patrones de contaminación. Los resultados mostraron concentraciones elevadas de metales pesados en las muestras analizadas, con cadmio y mercurio alcanzando valores máximos de 243.55 mg/kg y 2.23 mg/kg, respectivamente, siendo estas concentraciones significativamente más altas que las reportadas en otras zonas mineras. También se halló una alta presencia de plomo y hierro, lo que se relacionó con la presencia de minerales como la galena y la pirita en las escombreras. Como conclusiones, se destacó la grave situación ambiental y sanitaria que enfrenta La Pangui debido a la alta concentración de metales pesados, identificándose riesgos significativos para la salud humana, como trastornos neurológicos, renales y óseos, derivados de la exposición prolongada a estos contaminantes.
I Abuse Myself, You Abuse Me, He Abuses Me
Authors: D Jorge Martínez
Published: January 2025

It is important to clarify right now: it is not only the
abuse one receives from others, but there is a form of abuse
that is the worst of all, the one we inflict upon ourselves. Ten
years ago, I was writing my first book, ‘Between You and Me’;
one of the chapters says: “I have known many betrayals in my
life, but the only one I cannot stand is the betrayal of myself.”
When I talk about betraying oneself, I mean setting aside
one’s essence, staying with someone one never wished to be
with even for a minute, and that is a clear example of how we
are capable of betraying ourselves, complying with mandates
from the past or from others. The origin of this is nothing but
the guilt we feel when we transgress the rules imposed on us,
the desires of others, our own fear of not being loved, or the
need for approval.
Trauma and Transference-Countertransference: Working with the Wounded Self from the Jungian Perspective and the EMDR Technique
Authors: M Conti
Published: January 2025

In this paper I will present the use of EMDR (American acronym that stands for Eye Movement Desensitization and
Reprocessing) in classical Jungian therapy. This methodology is very important, not only for treating trauma and stressrelated problems, especially PTSD, but also for speeding up the process of individuation, especially when psychic complexes
and blocks are connected to traumas. A rather close alliance between patient and psychotherapist is absolutely needed for
ensuring the validity of the setting and a powerful container for the possible strong reactions and emotions of the patients. The
integration between Analytical Psychology and EMDR technique can be a powerful instrument for Jungian analysts, interested
in contemporary methods that can be very effective for the treatment of traumas.

Decent Work for a Better Life: Unpacking the Role of Career Adaptability and Sustainability
Authors: L Faria , C Gouveia , L Florêncio
Published: January 2025

The 2030 Agenda for Sustainable Development has integrated the International Labor Organization's Decent Work Agenda
into its broader vision to promote a more sustainable future for all. As one of the Global Goals for Sustainable Development, the
concept of decent work has been widely promoted in theory, practice and research to improve people's ability to experience
freedom, fairness, security and dignity at work. However, the evidence on the impact of decent work on individuals' quality
of life and long-term career prospects is still inconclusive. In this study, the relationship between decent work and quality of
life was examined, with career adaptability and career sustainability playing an indirect role. The study involved 218 people
between the ages of 19 and 71 who worked in various roles in the tourism industry. The results show a significant positive
relationship between decent work and quality of life. Decent work improves both career adaptability and career sustainability,
which in turn has a positive impact on quality of life. Serial mediation analysis confirms that career adaptability and career
sustainability mediate the relationship between decent work and quality of life (B = 0.493, p < 0.001). These results are clear
evidence that the development of career adaptability and the promotion of sustainable career practices are crucial when it
comes to translating decent working conditions into a higher quality of life for workers.

The aims of this research were to determine the effect of temperature and duration of blanching to the characteristics of breadfruit flour and to test the level of consumer preference of cake made from breadfruit flour. Completely randomized factorial design with two factors: temperature (60°C, 70°C, 80°C) and duration of blanching (4 and 6 minutes) was conducted. The parameters measured are fineness modulus, grain size distribution, bulk density, color index and organoleptic score of cake made from breadfruit flour as a part or overall materials. The results showed that the temperature and blanching time affect the fineness modulus and of breadfruit flour granules. The higher the temperature, the longer the blanching time, and the smoother the fineness modulus, the finer the breadfruit flour granules. While, the lower the temperature and the duration of blanching, the color index of breadfruit flour is getting closer to white. The cakes made from 100% of breadfruit flour still have lower preference score compared with the cakes made from 100%  of wheat flour in terms of taste, aroma, texture and color. Keywords: Blanching, Breadfruit, Flour.

The first factor is the duration of the suppression which consists of four levels, namely 60, 120, 180, and 240 seconds. The second factor is particle size which consists of 40 mesh (fine), 30 mesh (medium), 20 mesh (coarse), and mixed. Sawdust is taken from a furniture industry in Bandar Lampung, then dried in the sun to a moisture content of about 12%, then sieved. Pellet molding was carried out with a mass of about 3 grams of material using a hydraulic press with a mold diameter of 12 mm. Sawdust is fed into the mould, then pressed by a hydraulic system at a pressure of 2 tons (172 Mpa). Parameters observed included density, moisture content, water absorption, pellet strength, pellet color, ash content and durability index. Each measurement was carried out with three replications. The results showed that the pressing duration and particle size affected the pellet characteristics. Biomass pellet made from sawdust had characteristics such as density of 0.813-0.856 g/cm3, moisture content of 8.19-12.15 %, maximum water absorption of 7.06-9.32 %, drop resistance of 99.41-99.66 %, and ash content of 1.087-2.082 %. Keywords: Density, Durability Index, Duration of Compression, Particle Size, Moisture Content.

Uni- ja lepotottumuksiin vaikuttavat hyvin monet persoonallisuuteen, käyttäytymiseen, elämäntapaan, terveydentilaan sekä ulkoisiin nukkumisolosuhteisiin yhteydessä olevat tekijät.
Tässä artikkelissa, joka on ensimmäinen osa laajemmasta tutkimushankkeesta "Elintavat, uni ja vireystila", kuvataan keski-ikäisen kaupunkiväestön käsityksiä heidän itse kokemistaan nukahtamiseen ja unen laatuun vaikuttavista tekijöistä. Tutkimustulokset perustuvat postikyselyyn, jossa nukahtamista koskevat kysymykset esitettiin avoimina. Hyvin erilaiset asiat koettiin nukahtamisen kannalta tärkeiksi. Useimmin ilmoitettuja unta edistäviä tekijöitä olivat ulkoilu ja liikunta, lukeminen ja musiikki, saunominen, suihku ja kylpy sekä säännöllinen elämäntapa.
Nukahtamista haittaaviksi tekijöiksi ilmoitettiin muita useammin työstä johtuvat syyt, huolet ja ihmissuhteisiin liittyvät vaikeudet sekä kahvinjuonti illalla. Miesten ja naisten käsitykset nukahtamista haittaavista tekijöistä poikkesivat siten, että miehet mainitsivat tärkeimmiksi unen häiriötekijöiksi työhuolet ja naiset ihmissuhdevaikeudet.
Terveydenhuollon talous sekä julkisen ja yksityisen sektorin suhde Suomessa ja muissa OECD-maissa
Authors: Häkkinen Unto
Published: January 2025

Artikkelissa tarkastellaan Kansaneläkelaitoksen sosiaaliturvan tutkimuslaitoksessa meneillään olevan tutkimuksen sekä kansainvälisten vertailujen perusteella Suomen terveydenhuollon kehitystä. Terveydenhuollon kokonaismenot ovat Suomessa kehittyneet keskimäärin yhtä nopeasti kuin muissa OECD-maissa, kun maan vauraus otetaan huomioon. Julkinen rahoitus on Suomessa samansuuruinen kuin keskimäärin muissa OECD-maissa, joskin hieman pienempi kuin muissa Pohjoismaissa. Julkisen sektorin osuus palvelujen tuotannosta on Suomessa suurempi kuin muissa maissa, ja samalla tasolla kuin muissa Pohjoismaissa Ruotsia lukuunottamatta. Kansainvälisen vertailun perusteella terveydenhuollon laajalla yksityistämisellä ei pystytä hillitsemään terveydenhuollon kustannusten kasvua. Sellaista järjestelmää, joka samanaikaisesti minimoisi kustannukset sekä olisi mahdollisimman tehokas ja tasapuolinen, ei ole olemassa. Olisi tärkeää pohtia, miten nämä tavoitteet voidaan ottaa huomioon nykyisen järjestelmän puitteissa.

Authors: Rohim Abdal
Published: January 2025

This study investigated the protection of rights, equality, and justice for people with mental disorders (ODGJ) from the perspectives of health and Islamic law. This study aimed to determine and analyze the legal protection and fulfilment of health rights for people with mental disorders. This study employed the normative juridical approach and analytical descriptive research. It relied on primary and secondary data collected through library and field research, encompassing primary, secondary, and tertiary legal sources. The collected data were subjected to qualitative and quantitative analyses using a deductive method. These findings indicate that neglected people with mental disorders face barriers to healthcare access, such as a lack of health insurance and the absence of responsible family members. The government must ensure justice in mental health initiatives for neglected people with mental disorders, as they have the same rights as healthy individuals. Social justice should be upheld without discrimination. Islamic teachings emphasize fairness as a universal principle applicable to everyone, including those with mental illnesses. The government must provide legal protection for neglected patients with mental disorders and secure their rights, as outlined in the 45th Constitution (Article 28D, paragraph 1), Mental Health Law (Article 3C), and Human Rights Law. These regulations affirm the entitlement of all citizens to legal protections.

Published: January 2025

Nowadays, pornography has spread to all circles of society. It turns out that pornography is not only a consumption of young people or teenagers, but also a problem for adults. However, most scientific journals discuss the issue of pornography in relation to young people. It is as if pornography is only a youth problem. From the data obtained, it turns out that many adults also access pornography and not a few are already at the level of addiction. Even those who are supposed to be the guardians of morality, such as educators and the clergy, have problems in this regard, as Pope Francis has stated. Therefore, pornography has become a community problem that should be a common concern and should be handled together. In this article, the author tries to raise the issue of pornography, which has become a problem for all members of society. The research method taken is by using a literature study. The data is analyzed using the Interpretative Phenomenological Analysis (IPA) approach. As a theoretical framework to help the analysis, the author uses religious, moral, and social ethics theories and touches on psychological approaches. With this, the author found the impacts caused by pornography as well as efforts to deal with it.

By conducting the toben lewo ritual, the religious community in Botung village organizes, interprets, and reconstructs their lives within the framework of achieving collective salvation. Salvation is manifested in socio-religious harmony, which is also an implication of the mainstreaming of religious moderation in Indonesia. This study elaborates on three main questions. First, how is the toben lewo ritual conducted? Second, how do the people of Botung village interpret this ritual? Third, what are the implications in promoting religious moderation in Indonesia? A qualitative method was selected with the aim of exploring the knowledge, experiences, opinions, and feelings of informants regarding the toben lewo ritual as a social salvation system in the context of religious moderation. The study was conducted in Botung village, Adonara Island, East Flores Regency. The techniques of data collection were observation, interviews, and document studies. The data collection was collected from September 2021 to May 2023. Primary data was obtained by conducting structured interviews with ritual participants and the representation of women and youth. The secondary data were from previous studies and documentary photographs. The findings revealed that by carrying out the toben lewo ritual, the village will be freed from guilt as the cause of disasters and calamities, which disrupt its relationship with the divine, ancestors, humans, and the universe. The ritual serves to restore and mend these three-dimensional relationships. The ritual brings forth and affirms harmony with the divine, ancestors, people, and the universe. This study can serve as a gateway to promote the idealism of religious moderation in Indonesia and enrich the knowledge in the fields of sociology and anthropology.
Religion, Justice and Women: the Views of Dominican Christian Mystics Meister Eckhart and Franciscan Bonaventura

Mysticism was an interesting and fascinating phenomenon in medieval times. In that century, the scientific interest and views on mysticism that experienced high intensity, especially in its literature, also became a challenge from both religious and epistemological sides. This is not surprising, since visionary stories reflecting transcendental experiences associated with forms of religious spirituality could not be understood by (modern) rationality. Even today, rationalism and empiricism are popular for determining justice that materializes from development and knowledge in a measurable way. This also creates a dilemma, where the orientation of rationalism and empiricism emphasizes results rather than the relationship between humans and the Divine. The views of Christian mystics MeisterEckhart and Bonaventure provide an overview of the relationship between mysticism and social life. This article discusses the views of Dominican mystic MeisterEckhart and Franciscan mystic Bonaventure on religion, justice and women. These two Christian mystics emphasize the dimensions of human unity with God, the position of human beings, and human relations. At a time when the development of rationalism and empiricism is massive, mystical experience becomes one of the alternative views to revisit the relationship between humans that comes from unity with the Divine in the perspective of Religion, Justice and Women. This scientific work is studied using the literature method.
