Authors: Contreras-Velásquez Julio César , Bernal Omaira Suárez , Arias José Alban Londoño , Arenas Luis Eduardo Rodríguez , García-Navarro Jorge Isaac , Parias Carlos Hernán González , Sandoval Jessica Manosalva 
Published: September 2024

Objective: The article analyzes whether there is an association between the different levels of the BoP and the area of residence with the variables of access to essential utilities in a region of Colombia.

Theoretical Framework: The literature review addresses the concepts of access to essential utilities and the BoP Population.

Method: The data analyzed comes from 2,394 homes in the Norte de Santander region (Colombia), which were segmented by poverty conditions, resulting in 1,521 in the BoP. To establish the association between variables, the Mann Whitney U test was used; the magnitude of the association has been determined using Cramér's V coefficients.

Results and Discussion: Results show that cooking fuel, excreta disposal, and urban waste management services have a high association with the socioeconomic levels at the BoP; while the drinking water service has a moderate association, yielding a Cramer V value of 0.47. Regarding the area of residence, the independence between the variables Access to essential utilities and Area of residence is rejected; that is, they are associated. Little interest was evident on the part of public and private organizations in the essential services sector in serving this market segment, by not including it in their marketing targeting strategies. The finding was also that people from the BoP in Norte de Santander, Colombia, who reside in urban areas, have better access to these services than those in rural areas, confirming the hypotheses raised based on similar studies carried out in regions from Asia.

Research Implications: These results leads to recommending that companies in the essential services sector that have the BoP as their target market make a distinction in marketing strategies between the urban and rural markets of the BoP.

Originality/Value: The study uses an innovative socioeconomic level classification method that facilitates comparison with other regions by not using income level as the only variable.

Objective: The article analyzes whether or not there is an association between the different levels of the BoP and their area of ​​residence with the variables of access to ICT services in a region of Venezuela.

Theoretical Framework: The literature review addresses the concepts of access to Information and Communication Technology services, as well as the concept of BoP population.

Method: The data analyzed comes from 1,398 households in the Táchira region (Venezuela), which were segmented by poverty conditions, resulting in 675 in the BoP. To establish the association between variables, the Mann Whitney U test was used; The magnitude of the association has been determined using Cramér's V coefficients.

Results and Discussion: The results show that access to landline telephone and cable TV services present a moderate association, with respect to socioeconomic levels; while in cell phone service, television ownership and internet service, the association is low. Little interest was evident on the part of public and private organizations in the internet services sector in serving this market segment, as they did not include it in their marketing strategies.

Research Implications: These results allow companies in the ICT services sector that have the BoP as a target market to make a distinction in their marketing strategies between the levels of the BoP, since heterogeneity is evident.

Originality/Value: The study uses an innovative method of classifying socioeconomic levels that facilitates comparison with other regions by not using income level as the only variable.

One of the ways used by the Indonesian government so that people living in and around the forest can participate in managing the forest while getting economic and environmental benefits is through Social Forestry (Perhutanan Sosial) with five schemes offered according to the characteristics of the community. One of the schemes implemented by the people of Intu Lingau and Sembuan Villages is the Village Forest (the so-called Hutan Desa-HD). The Village Forest is still in the initial stages of implementation; of course, it is interesting to study how the community manages the village forest, what the benefits are, what problems they face and how they are resolved. The aim of this research was to examine the implementation of Village Forests, the problems or conflicts that arise and the mechanisms for resolving the problems.
This research was carried out in Intu Lingau and Sembuan Villages, East Kalimantan Province, Indonesia, from 2023 to 2024 with a focus on Village Forest management, which is operationally carried out by the Village Forest Management Board (so-called LPHD-Lembaga Pengelola Hutan Desa). Data was collected using direct field surveys, focus group discussions (FGD) with LPHD and in-depth interviews with key respondents. The information and data collected were analyzed using the descriptive qualitative method. The Sustainability principles of Ostrom and Successful Principles of Agrawal were also used for validation of the implementation of Village Forest.
The results of the research showed that the implementation of the Village Forest that has been carried out by the LPHD includes taking steps to secure the Village Forest area by making boundary marks around the area, carrying out area patrols, and operationally managing the Village Forest through five Social Forestry Business Groups (so-called Kelompok Usaha Perhutanan Sosial-KUPS) in Intu Lingau and seven KUPS in Sembuan. In the implementation of Forest Village, there were several internal and external conflicts. The conflict resolution mechanism used is negotiation and consensus because it depends on the intensity and who was involved in the conflict. It is recommended that the management board strongly support KUPS in running the Program for the benefit of the community.
Invasive pituitary adenoma presenting with cerebrospinal fluid rhinorrhea and meningitis – A case report
Authors: Javed Zanib , Saeed Zunaira , Khan Sibgha , Ali Laghari Altaf 
Published: September 2024

Background:
Most pituitary neuroendocrine tumors are benign, except some adenomas that show invasiveness and are called invasive pituitary adenomas. These are challenging and rare pathologies.

Case Description:
We present a case of a 40-year-old male who presented to the emergency with seizures, rhinorrhea, headache, and drowsiness. Radiology images showed a sellar mass with supra-sellar extension and pneumocephalus. The pituitary profile was within normal limits. The patient underwent bifrontal craniotomy and maximum safe resection of the lesion with cerebrospinal fluid (CSF) leak repair and lumbar drain insertion. Histological examination and immunohistochemical stain were consistent with pituitary adenoma. Postoperatively, there was no CSF leak, and the patient’s Glasgow Coma Scale improved.

Conclusion:
Rhinorrhea is a unique presentation for pituitary adenoma. According to the current literature, surgery is the only effective treatment as part of the management of invasive pituitary adenomas, along with a multidisciplinary approach.
Spontaneous spinal epidural hematoma in infants: A case report and review of the literature
Authors: Hammoud Marouane , Mohammed Hmamouche Oualid , Chakour Khalid , Chaoui Mohammed El Faiz 
Published: September 2024

Background:
Spontaneous spinal epidural hematomas (SSEHs) are exceedingly uncommon, especially in infants, with only two reported cases. Diagnosis can be delayed due to the nonspecificity of presenting symptoms.

Case Report:
We present a case of SSEH in a 10-month-old boy admitted to the pediatric emergency department with a 5-day history of progressive lower extremity motor weakness. There was no history of prior trauma. Magnetic resonance imaging of the spine revealed a posterior epidural hematoma extending from C7 to L4. After hematoma evacuation, the patient’s neurological status gradually improved, and no sensorimotor deficit was present 3 weeks postoperatively.

Conclusion:
Our case suggests that surgical intervention can lead to an excellent prognosis for SSEH in infants, even if the diagnosis is delayed.

Published: September 2024

Рассматриваются вопросы рационального распределения функций между звеньями комплекса управления беспилотными летательными аппаратами и оптимизации режимов их загрузки для повышения автономности и надежности. Функции распределяются между тремя системными составляющими (звеньями) комплекса управления: наземными автоматическими станциями командно-измерительных систем, бортовыми системами управления летательных аппаратов и операторами. Часть функций назначается однозначно без альтернатив, а функции, которые могут существенно пересекаться и выполняться разными элементами системы управления, требуют специального рассмотрения. В ряде случаев распределение функций, установка режимов загрузки и вложение средств в построение многофункционального комплекса управления допускают постановку оптимизационных задач, что представляет существенный интерес. Приведены примеры возможных постановок некоторых оптимизационных задач в общем виде, даны обобщающие выводы.
The article considers the issues of rational distribution of functions between the links of the unmanned aerial vehicles control complex and optimization of their loading modes for increasing autonomy and reliability. Functions are distributed between the three system components (links) of the control complex: ground automatic stations of command and measurement systems, onboard control systems of aircraft and operators. Some functions are assigned definitely without any alternatives, and functions that can significantly overlap and be performed by different elements of the control system require special consideration. In some cases, the distribution of functions, the installation of loading modes and investment in the construction of a multifunctional management complex allow the formulation of optimization problems, which is of considerable interest. The examples of possible statements of some optimization problems in general form are given, as well as general conclusions are made.

В статье приводятся результаты теоретического обоснования метода идентификации сложных динамических объектов при штатных условиях эксплуатации на основе запасов работоспособности и результатов статистических испытаний (метод Монте-Карло). Доказано, что имеет место монотонная зависимость вероятности выполнения заданных ограничений на допустимые отклонения невязок между результатами летных испытаний и расчетов по методу Монте-Карло и предложенной формой запасов работоспособности. Определяется случайная реализация, которая ближе всего по вероятности идентификации подходит под летные испытания и которая однозначно определяет весь перечень возмущенных параметров, внешних и внутренних возмущений. На примере применения разработанной методики и программного обеспечения идентификации к анализу пуска ракеты-носителя «Союз-2» (Л/И № 2) с космическим аппаратом «Метеор-М2.1» с полигона «Восточный» 28.11.2018 г. показана эффективность метода, позволившая выявить ряд важных неточностей математической модели системы по сравнению с результатом летных испытаний.

The proposed approach based on efficiency margins and the results of probabilistic tests (Monte-Carlo method). It is proved that there exists the monotonic dependency of fulfillment probability of feasible errors deflection specifi ed constraints between flight test results and Monte-Carlo estimations, and provided efficiency margins form. In this method we determine the random realization, which is closer in terms of identifi cation probability to fl ight tests and which is explicitly defi nes full list of disturbed parameters, internal and external disturbances. The effi ciency of the approach is shown on the example of application of this approach and corresponding identifi cation software to the analysis of carrier rocket «Soyuz-2» launch (flight tests № 2) with the spacecraft «Meteor-M2.1»… from the «Vostochny» space center 28/11/2018. This application allows us to detect the number of signifi cant inaccuracies of mathematical model versus the flight test results.

На основе системного подхода разработана информационно-технологическая модель кислородного баланса водотоков при загрязнении нефтяными выбросами от аварийных разрушений подводных переходов нефтепроводов. Разработаны алгоритмы решения дифференциальных уравнений системного кислородного баланса в одномерном приближении в зависимости от времени для оценки динамики биохимической потребности, дефицита и концентрации кислорода в воде, реализованные в прикладной среде MathСad. Решена практическая задача по вычислению расстояния от створа аварийного выброса нефти до створа максимального дефицита кислорода в водотоке при равномерной и постоянной скорости течения. Полученные результаты могут быть использованы при разработке автоматизированных имитационных моделей оценки ущерба окружающей среды при аварийных разливах нефти от аварийных разрушений подводных переходов нефтепроводов.
In this paper, based on the system approach, an information and technological model for the oxygen balance of watercourses was developed in the event of pollution by oil spills from accidental destruction of underwater oil pipeline crossings. Algorithms for solving the differential equations of the system oxygen balance in the one-dimensional approximation as a function of time have been developed to estimate the dynamics of the biochemical demand, oxygen deficiency and concentration in water, realized in the MathСad application environment. A practical problem was solved for calculating the distance from the emergency discharge line to the maximum oxygen defi cit in the watercourse with a uniform and constant fl ow velocity. The obtained results can be used in the development of automated simulation models for assessing environmental damage in emergency oil spills from accidental destruction of underwater oil pipeline crossings.

Authors: Хрущева М.Л. , Цирлина Г.А. 
Published: September 2024

В работе рассмотрены направления исследований основателя известной электрохимической школы акад. А.Н. Фрумкина в конце 20-х–начале 30-х гг. XX века, после его переезда в Москву. Этот начальный период становления школы был отмечен награждением А.Н. Фрумкина премией имени В.И. Ленина (1931). Доминирующая тематика работ по сорбционным процессам на углях указывает на то, что премия была присуждена именно за эти исследования, имеющие высокую практическую значимость. Научные биографии соавторов работ А.Н. Фрумкина по «угольной» тематике (Р.Х. Бурштейн, Б.П. Брунс, С.Д. Левина, С.С. Васильев) показывают, что генетически школа Фрумкина связана с выдающимися представителями более раннего периода развития электрохимии в России и Украине (в том числе И.А. Каблуковым, В.А. Плотниковым, В.А. Кистяковским).
We consider the research topics of academician A.N. Frumkin, the founder of a famous electrochemical school, at the end of 1920th and beginning of 1930th (shortly after he moved to Moscow). During this starting period of Frumkin school its founder had been awarded the Lenin Prize (1931), the highest USSR state award. As the articles devoted to sorption processes on the coals dominated during this period, one can conclude that the Prize was awarded just for this coal research, being of high interest for applications. Scientific biographies of coautors of Frumkin’s coal articles (R.Kh. Burshtein, B.P. Bruns, S.D. Levina and S.S. Vasil’iev) demonstrate that Frumkin school is genetically linked to the outstanding Russian electrochemists of the previous period, including I.A. Kablukov, V.A. Plotnikov, and V.A. Kistyakovskii.

В статье рассматривается начало миссионерской работы в Корее представителя Русской православной церкви архимандрита, а в дальнейшем епископа Хрисанфа (Щетковского). Содержится материал, раскрывает особенности православной миссионерской деятельности среди местного населения Кореи. Говориться о тех трудностях и с чем пришлось столкнуться на начальном этапе в деятельности миссии. Автор приходит к выводу о том, что успехи деятельности нашей миссии были менее впечатляющими, чем успехи западных миссий, в виду того, что Русская православная миссия исполняла роль только лишь своеобразного «проводника» религиозно – культурного влияния и не стремилась вмешиваться во внутренние дела этой страны в отличии от западных миссий.
The article deals with early missionary work in Korea, the representative of the Russian Orthodox Church Archimandrite and later Bishop Chrysanthus (Shatkovskogo). It contains material that reveals the peculiarities of Orthodox missionary activity among the local population of Korea. The difficulties encountered and the diffi culties encountered in the initial phase of the mission are described. The author comes to the conclusion that the success of our mission was less impressive than the achievements of the Western missions, in view of the fact that the Russian Orthodox mission played the role only a kind of «conductor» of the religious and cultural infl uence and did not seek to interfere in the internal Affairs of this country in contrast to the Western missions.
