Information is a necessity for the interests of government, the economy, social culture, as well as defense and security in the era of industrial revolution 4.0. Since 1976, the Indonesian government has been working on developing a satellite communication system starting with the Palapa A1 Satellite, followed by its subsequent generations. However, this system has limitations, particularly in providing coverage to rural areas in Indonesia. To address this issue, the government has started the procurement of the Wahana Dirgantara Super or High-Altitude Platform Station (HAPS) in Indonesia. HAPS are stations positioned at altitudes of 20 to 50 km above the Earth's surface. Given Indonesia's geographical location, HAPS is seen as the most suitable solution as it utilizes non-ground terrestrial technology to improve information and communication technology coverage in rural areas. However, the location on which the HAPS is positioned might trigger new issues, particularly with regard to state sovereignty and disruption of flight traffic. The operation of HAPS also needs further consideration so that the protection of personal data in Indonesia will not be disrupted. This article employs normative juridical research as a methodology. The research collected and analyzed primary sources in the form of law, regulation, and policy at the national and regional levels, as well as secondary sources that are available in textbooks, journal articles, and website content. This article aims to explain the development of HAPS regulations based on international law and national law and to examine the legal issues related to the procurement of HAPS in Indonesia . At the end, this article suggests that it is necessary to regulate HAPS in Indonesia with reference to aviation safety, security, and liability issues as well as maintaining state sovereignty and ensuring personal data protection.

Authors: Ojha Rajdeep , Singh Abhinav , George Jacob , Chandy Bobeena Rachel 
Published: August 2023

Objectives:
Suprasacral spinal cord lesions are prone to have neurogenic detrusor overactivity leading to urinary incontinence. Current medical management has known side-effects and often surgical managements are irreversible. Electrical stimulation to modulate spinal reflex pathway having same nerve root as urinary bladder is reported in the literature. This study aimed to reduce detrusor overactivity in patients with spinal cord injury (SCI) using surface electrical stimulation of medial plantar nerve at the sole of foot.

Materials and Methods:
Twenty adults with SCI having episode of at least 1 leak/day due to detrusor overactivity as diagnosed by cystometrogram (CMG), were on clean intermittent catheterization and ankle jerk was present consented for the study. Participants were asked to maintain bladder diary a week before and during 2 weeks of treatment. CMG was done on day-0 and day-14. cmcUroModul@tor®, an inhouse developed electrical stimulator was used for ½ h daily for period of 2 weeks. Patient satisfaction feedback questionnaire was taken on completion of treatment. CMG data were analyzed using Wilcoxon signed-ranked test while bladder diary was analyzed using binomial distribution. P < 0.05 was considered as statistically significant. Institutional Review Board (IRB) and ethics committee of Christian Medical College, Vellore, approved the study (CMC/IRB/11061).

Results:
Statistical significant improvement in maximum detrusor pressure (P = 0.03) and cystometric capacity (P = 0.04) was observed. Of 20 subjects, 18 showed improvement in bladder diary.

Conclusion:
Neuromodulation of medial plantar nerve at sole of foot by surface electrical stimulation is non-invasive, cost-effective, and alternative simple treatment modality for urinary incontinence due to detrusor overactivity.
MUSICALIZATION OF THE NOVEL “NOCTURNE B-MOLL” BY Y. KOSACH AND “THIRST FOR MUSIC” BY V. PETROV (DOMONTOVYCH)
Authors: Zviahina Hanna , Pototska Olena 
Published: August 2023

The article is devoted to the musicalization of the novel “Nocturne b-moll” by Y. Kosach and “Thirst for Music” by V. Petrov (Domontovych). It was noted that both the studied authors became the founders of the Artistic Ukrainian Movement (MUR). This is an organization of Ukrainian émigré writers, founded in Germany in 1945. Small prose, which prevailed in the mentioned period, was distinguished by a variety of themes and writer techniques. Common and distinctive modern trends are defined using the comparative aspect. For example, fragmentation, the splitting the world into visual sensations, including color, graphic and olfactory, fixation by the characters of individual details of the interior, clothing, and appearance of other characters, film coating method. Among the linguistic features, we find direct speech and improper direct speech in Kosach novel, and indirect speech in Domontovych novel. Attention is paid to determining the sources of musicality of the works of the specified authors. Ways of displaying music in works are highlighted. The considered novels of Kosach and Domontovych have an organic combination of musical and theoretical positions with the views of the writers on literature. The tendency towards musicalization is reflected in the title, borrowed elements of “musicality” are used in fragments interpreting listening or performing music (in Domontovych) and a certain subtext. For Kosach, music shapes reality, replaces words and actions, expresses emotions. It was concluded that the constant discussion of music is the same in both authors. The authors treat it as something sacred, completely incomprehensible to people.
CONCEPTUALIZATION OF THE LOCAL SPACE OF KYIV IN THE LANGUAGE OF ARTISTIC PROSE OF THE 20TH CENTURY
Authors: Holikova Nataliia 
Published: August 2023

The article examines the linguistic features of the conceptualization of the local space of the “Kyiv” mindset in the language of artistic prose by two outstanding Ukrainian writers of the 20th century. – V. Pidmohylnyi and P. Zahrebelnyi. Emphasis is placed on the fact that the local-spatial constant of the linguistic-cultural concept of the proper name “Kyiv”, reflected in the artistic discourses of artists, captures many urban and natural objects, which partially reflect the extremely complex topographical and coordinate grid of the real city. The system of urbanonyms, which represent the specifics of the individual and linguistic pictures of the world of novelists in terms of fixing the realities of the same city in different historical periods of its life, is studied. From the point of view of linguistic stylistics, a comparative analysis of expressive and figurative means of addressing the “Kyiv” mindset in the novel “The City” by V. Pidmohylnyi and in a number of historical novels and works about modernity by P. Zahrebelnyi was carried out. It is noted that the study of the verbalized constant of the local space of the city is an important issue not only for integrative linguistic stylistics, but also for cognitive linguistics, conceptology, linguistic and cultural studies, etc. The semantic-stylistic and logical-cognitive transformations of the internal forms of a number of proper names, which in P. Zahrebelnyi's artistic discourse have consistently evolved from an urbanonym to a concept have been traced. It was concluded that V. Pidmohylnyi, having “immersed” Stepan Radchenko, a rural man, in the urbanized space with its anthropogenic landscape, was one of the first Ukrainian writers of the beginning of the 20th century. conceptualized the city as a determining factor in the civilizational and historical development of society. In the artistic discourse of P. Zahrebelnyi, numerous linguistic units that nominate the real landscape of the city reflect the philosophy of the author's vision of Kyiv as a unique, originally Ukrainian city, as it appears in the national-linguistic picture of the world.

Aim. To test the hypothesis that early detection of clinically significant patients with high risk of developing intra-abdominal hypertension in cardiac surgery may be based on an increase in the level of fatty acid-binding protein.Material and Methods. Concentrations of fatty acid-binding protein (I-FABP) were measured in urine samples taken from 82 patients after cardiac surgery with cardiopulmonary bypass. The data were compared with clinical manifestations of the perioperative period, as well as changes in pH and lactate levels in arterial blood.Results. Statistically significant differences were revealed between the study groups in the cases of increased intra-abdominal pressure, duration of ventilation, and the number of cases of intestinal failure. The level of I-FABP increased in the patients of both groups after removal of the aortic clamp in 2 hours, 12 hours, 24 hours after surgery. Conclusions. The I-FABP level can be a valuable marker for early detection of patients with the development intra-abdominal hypertension of after cardiac surgery. The measurement of I-FABP can serve as a guideline not only for the identification of patients with intra-abdominal hypertension, but also for the initiation of therapeutic measures aimed at minimizing further deterioration of intestinal function.

Between Separation and Integration: Moldova’s Bulgarian Minority and the Collapse of the Soviet Union
Authors: Harrington Keith 
Published: August 2023

Abstract
This article investigates how the Bulgarian community of southern Moldova experienced the collapse of the Soviet Union. It questions why Moldova’s Bulgarian population refused offers from the Gagauz and Ukraine’s Bulgarian minority to join them in their quest for autonomy. The fact they chose not to is somewhat puzzling, as Moldova’s Bulgarian minority shared many of the same grievances as the Gagauz and Ukrainian Bulgarians, and they were offered considerable concessions to join each movement. I argue that there were several reasons for this. Firstly, Bulgarians in Taraclia distrusted the Gagauz and Ukrainian Bulgarians. Secondly, local political elites quickly realised they could extract greater concessions from Chișinău by aligning with the central government during such a tumultuous period. Finally, relations between Taraclia and Chișinău were characterized by a high degree of pragmatism.
