Authors: Li Yiming , Liang Xitao , Xie Wenwu , Zhu Juan
Published: March 2023

As a new communication technology, Intelligent Reflecting Surface (IRS) can intelligently reconfigure the wireless propagation environment by integrating many passive/active reflective elements on the plane. According to the characteristics that IRS can adjust the propagation channel intelligently, this paper applies IRS to wireless security communication, and studies how to make the security rate reach the optimal security capacity from the perspective of optimization technology. In this paper, two schemes of passive/active IRS are considered, and the corresponding safety rate maximization algorithm is proposed. In view of the nonconvexity of the objective function, on the one hand, in the passive IRS scheme, the Dinkelbach method is used to transform the objective function into a form that is easy to handle, and the original problem is transformed into a convex problem through the continuous convex approximation method; On the other hand, under the active IRS scheme, aiming at the complexity of the original problem, the first order Taylor expansion is used to obtain the lower bound of the optimization problem, and a minimax optimization algorithm is proposed. Finally, the performance of the proposed algorithm is verified by simulation. The simulation results show that the algorithm designed with active IRS has better security rate than the algorithm designed with passive IRS under the same parameter settings.

The study aims to avoid the phenomenon that thousand cities seem the same in the construction of smart cities and the efforts of all walks of life are jointed to implement the construction of smart cities and the creation of city brands. First, the basic theory of smart city construction is introduced. Second, the restricting and promoting factors influencing smart city construction and development are analyzes, and the evaluation system of smart city development is established. Then, the model for smart city construction and development based on the neural network is implemented. Finally, some domestic cities are selected as the dataset to build a training model, and the city brand optimization strategy is proposed. On this basis, an evaluation system for smart city development based on the intelligent neural network and Grey relational analysis Back Propagation Neural Network (GRA-BPNN) is obtained. The entropy weight method (EWM), grey relational analysis (GRA) method and the evaluation method based on Technique for Order Preference by Similarity to an Ideal Solutionv (TOPSIS) are regarded as the members of the control group, and the results of different methods for evaluating the development of smart cities are compared. The results show that the modeling of smart city construction based on neural networks can help to implement an evaluation model for smart city construction and development, and it can help evaluate smart city construction and development accurately. And then the corresponding strategies are proposed to speed up the construction of smart cities with its local characteristics, and then city brands are built. Compared with other evaluation algorithms, the performance of the algorithm proposed is better and more stable and the evaluation results are more reasonable than those of the others, which can prove that the evaluation algorithm is feasible and scientific. This study provides a new idea for the application of deep learning to smart city construction and city brand building.

Authors: Lu Chang-Ling , Hu Zhao-Fei , Kang Xiao-Rong , Zheng Ke-Long
Published: March 2023

Based on the traveling wave reduction method with a perturbed initial
solution and the F-expansion method, a class of explicit exact solutions of
the (2+1)-dimensional CDGKS equation are obtained through the symbolic
computation. Moreover, both the interaction behavior between parameters and
the perturbation degree of periodic wave and Gauss wave to rational pulse
wave, and the correlation of parameters to the superposition degree of the
interaction energy between solitary wave and rational pulse wave are
discussed. Finally, numerical simulations are shown to demonstrate the
mechanism of the above solutions.

Authors: Shi Xiao-Jun , Li Jia-Nan , Li Cong , Wang Jiu-Quan , You Zhen-Xi
Published: March 2023

The zero-sum game between the strength of deep in-situ thermal insulation
coring structures and the performance of passive thermal insulation
materials seriously restricts the exploration and development of deep
resources. In this paper, an innovative thermal insulation coring structure
based on passive thermal insulation material is designed, and a strength
analysis of thermal insulation material is carried out based on the elastic
theory of multilayer cylinders, which reveals the stress distribution and
deformation law of thermal insulation material in a deep in-situ
environment. The reliability of the results is verified by comparisons
between the numerical simulation and theoretical derivation. The results
show that for deep coring environments of 150?C and 140 MPa, the wall
thickness and diameter of the corer can be greatly reduced by directly
coating the insulation material on the surface of the core barrel. This
paper can provide a reference for the design and engineering application of
deep rock in situ thermal insulation coring systems.

Published: March 2023

Background/Aim. The radial inclination (RI) and volar cortical (VC) angle values used in the treatment of radial distal end fractures may vary depending on factors such as the age and gender of the patient. That raises the question of the compatibility of the standard anatomical plates, which are frequently used in the surgical treatment of these fractures. The aim of the study was to evaluate the VC and RI angles depending on the age and gender of subjects and determine the correlation between these two angles. Methods. A total of 121 individuals (59 females and 62 males) aged 10?65 years were included in the study. The individuals were divided into two groups: a group of 60 adolescents (31 females, 29 males) 10?20 years old and a group of 61 adults (28 females, 33 males) aged 20?65 years. The subjects were also evaluated between themselves, independently, within each age group. Radiographic images were evaluated by using the 3.0.1.55 version of the KarPacsViewer application. Measurement points were determined, and angles between these points were measured. Statistical analyses were made using the SPSS 15.0 program. Results. When the correlation for 121 individuals was assessed independently of their gender, no statistically significant relationship was found between the RI angle and age (p = 0.616; r = -0.046). A statistically negative (or opposite) relationship was found between the VC angle and age (p < 0.001; r = -0.396). When women and men were compared in terms of the RI and VC angles, no statistically significant difference was found (p = 0.958, p = 0.165, respectively). The VC angle decreased as the age increased in females (p = 0.004; r = -0.365), while both the RI and VC angles decreased with increasing age in males (p = 0.032, r = -0.273; p < 0.0001, r = -0.445, respectively). Conclusion. Our findings regarding the RI and VC angles offer an advantage in terms of determining which plate designs are most appropriate for planning surgical procedures and treatment processes.
Tambach, Economic Change and Keiyo Struggle for the School, 1902-1939
Authors: KIPKOSGEI EVELYN , Kipsang Tarus Isaac
Published: March 2023

The establishment of African Government School, Tambach in 1927, epitomised Keiyo and Marakwet struggle for what they considered a valuable asset to their society. Missionary enterprise had neither converted the two communities to Christianity nor created a school for them, as was the case in other parts of Kenya. Responsibility fell on the Local Native Council (LNC), which had become operational in 1925. The LNC wanted a secular education geared towards literacy for the Keiyo and Marakwet as opposed to the government and missionary type of education which was technical oriented and evangelical. While missionaries viewed western education as a vehicle for spreading the gospel, the colonial state demanded that African education meet the needs of the Uasin Gishu settler labour market. Both, however, were desperately handicapped by lack of resources and each Keiyo adult and Marakwet had to contribute two shillings each in the form of taxes to construct Tambach School. The colonial government reluctantly facilitated the infrastructural and curriculum development as part of their control and domination strategy. This essay builds on „the struggle for school‟ paradigm elaborated by John Anderson that Africans in Kenya played a major role in the early development and control of schools in Kenya. But for a start, such a history cannot be complete without a brief narrative of colonial economic change and of Tambach enclave as a hill station that was scenic and exotic, situated at mountain range of the picturesque Elgeyo escarpment.

Published: March 2023

The COVID-19 pandemic has increased inflation and poverty rates in many cities, thus requiring considerable attention from the government as a policymaker. Therefore, this study aims to cluster regencies/cities that need mitigation priorities from the Indonesian government based on inflation and poverty rates in 2021. Four machine learning methods, namely k-Means (KM), Partitioning around medoids (PAM), Ward, and Divisive analysis (Diana) are utilized and compared to achieve that purpose. Clustering 90 regencies/cities in Indonesia produced five optimal clusters. Furthermore, the clustering results were validated using the Silhouette width (SW) and Dunn index (DI). The results showed that the k-means method produced the most compact cluster. Hence, this study's results can be utilized as a reference for the government in determining the steps and priorities of economic policy in Indonesia.

Published: March 2023

Introduction: Uterine prolapse grade III and IV or advance stage uterine prolapse manifest in symptoms that reduces the quality of life of women. Sacrouterine ligaments are the main support of the uterus in preventing advanced stage uterine prolapse. Remodeling process occurs in the extracellular matrix and there are many genes that are involved in the process. One of the gene that is involved is the HOXA13 that upregulates the components of extracellular matrix. This study focuses on the expression of HOXA13 in the sacrouterine ligament as a risk factor in occurring advanced stage uterine prolapse.

Methods: We designed an unmatched case-control study to include 44 cases of women that was performed hysterectomy in Prof I. G. N. G Ngoerah Hospital. 22 cases are with advanced stage uterine prolapse and the 22 controls are with non-uterine prolapse. Sacrouterine ligaments samples were collected, and immunohistochemistry was performed. Chi-square test was done to find the odds ratio of the low expression of HOXA13 with advanced stage uterine prolapse.

Results: We found 16 (72%) women in this case group had a low HOXA13 expression, while only 5 (22%) women in the control group had a low expression of the gene. Low expression of HOXA13 in sacrouterine ligament has 9 times risk of having advanced stage uterine prolapse (OR = 9.067; 95% CI = 2,3-36.65; p =0,001) compared with the high expression.

Conclusion: Low expression of HOXA13 increases the risk of advanced stage uterine prolapse and subsequently may become a possible predictor for uterine prolapse.

Wind turbines are one of the machines that are currently still used to convert wind kinetic energy so that they can be used by humans such as to drive pumps in agriculture and produce electrical energy. Savonius turbine is a vertical axis turbine that is currently widely used as an electrical energy generator, this wind turbine is a type of drag type wind turbine that has a simple design that is in the form of a semicircular curved blade side. Therefore, the author is interested in researching the resulting performance including turbine rotational speed, power generated, and wind turbine efficiency against the variation of the blade radius. The method used is experimental, the stages of this research are in the form of literature studies, making savonius turbines, testing savonius turbines with variations in blade radius as well as data retrieval, data processing, and analysis. Based on the data obtained, the rotating speed of the turbine is influenced by variations in the radius of the blade. The larger the blade radius, the smaller the turbine rotational speed. The maximum turbine rotation speed at blade radius 63 is 173 rpm, while at blade radius, 88 is 118 rpm and at blade radius 113 is 115 rpm. So the highest turbine rotating speed at a radius of 63.

Advances in technology have an impact on increasing the population of vehicles as a means of transportation. Currently the vehicle's work system to produce energy still uses internal combustion. The fuel used as an energy source is still dominated by fuel oil. If exploitation continues without using alternative fuels, it is predicted that there will be a fuel crisis in the future. Therefore, efforts are needed to conserve fossil fuels. One way to do this is by adding bioethanol. This research was conducted by adding bioethanol from cassava to gasoline type fuel with an octane rating of 92. This study aims to determine the performance and fuel consumption. Tests varied the fuel composition by 5%, 10%, 15%, 20% with engine speed of 1,000 to 8,000 rpm. The test results show that the composition of Pertamax 80% with 20% bioethanol produces the highest power and torque of 8.87 hp and 8.32 N.m, but for the lowest fuel consumption the fuel composition is Pertamax turbo 100% with a fuel consumption value of 38.8 ml/min.

Abstrack: The success in learning is the hope of the implementation of education. One of the success keys factors is the professionalism of the teacher. Lesson plans need to be made by a teacher before teaching. This will determine what kind of learning activities are designed by the teacher so it can facilitated the skill development of the students. This ability is an obligation and becomes part of the professionalism of the teacher. There needs to be habituation and training for a teacher to be able to do this, of course this can be done when they are at the teacher education level (prospective teachers). Their experience while undergoing the process of becoming teachers will certainly determine it, for this reason lectures that train teacher professionalism need to be updated in presenting it in order to facilitate prospective teachers to be able to diligently and carefully make learning plans. Through the use of digital learning media, it can be a way of updating in lectures to train the professionalism of prospective teachers so that in the future they become competent teachers, especially lesson plan. This article discusses studies regarding efforts to train teacher professionalism, especially in making lesson plans from an early age through lectures that use digital learning media.

Published: March 2023

This research aims to remove the moisture (latent load)  generated by the occupants of the space due to the addition of water vapor resulting from the natural breathing process, the perspiration that evaporates in the air of the space. In sum, the dehumidification system (DS) reduces the amount of latent load or removes it completely to reduce the load on the air conditioner. In this study, adsorbent materials, such as silica gel-Blue and sawdust were used and their effectiveness was compared when used in dehumidification. The results of these experiments for June showed that the adsorption rate and temperature of the blue silica gel - Blue were 20% and 34°C, while the humidity and temperature increased to 52% and 36°C when using sawdust (when rotating the dehumidifying system hourly).  Moreover, for July, the adsorption percentages of silica gel-Blue were 8%, while the moisture content of sawdust increased to 49%, while the adsorption percentage in August when using silica gel - Blue was 10% and the relative humidity increased until it reached 39% when using sawdust. While the temperatures in July and August reached their maximum value when using silica gel - Blue and sawdust at 35°C and 36°C, respectively.  The water vapor absorption rate in June, July, and August is 83.39 g, 70.82 g, and 65 g, respectively.  While the drying process increased during these months due to the increase in solar radiation.  Therefore, silica gel - Blue has proven its effectiveness by absorbing moisture more efficiently than sawdust.  However, when drying sawdust, it was more effective and faster drying than silica gel - Blue.

Excess and malnutrition in adulthood are serious problems that increase the risk of disease. Nutritional status can be influenced by several factors, one of which is coffee consumption and screen time. Coffee consumption and screen-time can be impactful to a person's length of sleep. The purpose of this study was to clarify the relationship between screen time and coffee consumption with length of sleep and nutritional status in the population aged 20 to 45 years who lived in Buttu Sawe Village, Pinrang District. This type of research is observational research with a cross-sectional research approach. The sample is the entire adult community aged 20-45 years in Buttu Village, Pinrang Regency. The sampling technique was carried out using the purpossive sampling method of 100 people. Bivariate analysis using pearson correlation test. The results showed that there was no relationship between coffee consumption (r = 0.150, p = 0.136) and nutritional status (r = -0.087, p = 0.388), there was no relationship of screen-time with sleep length (r = -0.020, p = 0.847) and there was a screen-time relationship with nutritional status (r = -0.434, p = 0.000).

The presence of the heavy metal lead (Pb), which accumulates in water and sediment, will enter into the life of organisms which can have a toxic effect on the organisms in it. This study aimed to analyze the health risks of consuming Mujair fish (Oreochromis Mossambicus) which contains the heavy metal Pb in the river flow of Soyoan Village, Ratatotok District, Southeast Minahasa Regency. The research method was descriptive with an environmental health risk analysis (ARKL) approach. Determination of lead levels in fish, water, and sediments used the Atomic Absorption Spectrophotometer method with a graphite furnace. The results showed that the average Pb in Mujair fish was 0.23 mg/kg, the average Pb in water was 1.48 mg/liter, and the average in sediment was 52.98 mg/kg. Pb concentrations in aquatic fish and sediments had exceeded the threshold. The Risk Quotion (RQ) value wasstill below 1 (RQ < 1), meaning that Mujair fish (Oreochromis Mossambicus) in the Soyoan river was still safe for consumption. The ECR value ≤ 10-4 indicated that making risk management was not something that needs to be prioritized. However, the presence of high concentrations was an indicator so that the rate of intake and frequency of exposure can be reduced. In Islamic teachings, it has been explained that damage to the environment due to human actions has an adverse effect on the biota and threatens the surrounding community's health.

Transgender is a group with a high risk of HIV AIDS transmission due to the large number of base areas for transgender to conduct sexual transactions with sex partners. Changing behavior among transgender sex workers is still complicated because of the low use of condoms among transgender women. The study aimed to analyze the relationship between perceptions of vulnerability to contracting HIV with the consistency of using condoms among transgender sex workers to prevent HIV AIDS in the city of Makassar. This type of research was mixed methods research with a quantitative and qualitative approach using a sequential explanatory design (combination model). The quantitative data collection technique used a cross-sectional research design. The qualitative data used in-depth interviews with a research design using case studies to strengthen the quantitative results obtained from HIV-positive transgender sex workers. The number of respondents in this study was 60 people. The results showed a relationship between perceived vulnerability to contracting HIV and the consistency of condom use among transgender sex workers. Islam explicitly states that homosexual and lesbian behavior is a form of deviant sexual behavior contrary to human nature. Sex in Islam is not just to satisfy lust but has an important goal regarding the continuity of life, namely continuing offspring/ reproduction so that same-sex relations are unlikely to produce offspring, so this is not in line with the purpose of sex in Islam.

Exudative enteropathy is a clinical syndrome characterized by excessive loss of proteins through the gastrointestinal tract and is a rare complication of various gastrointestinal diseases. One of the rarest causes of protein malabsorption is Langerhans cell histiocytosis, which occurs as a result of inflammatory neoplasia of myeloid precursor cells caused by mutations in the mitogenactivated protein kinase pathway. Abnormal proliferation and accumulation of Langerhans cells in the intestinal wall leads to a violation of the outflow of lymph, and causes clinical manifestations characteristic of enteropathy. Given that the lesion of the gastrointestinal tract with histiocytosis from Langerhans cells occurs in 2–3% of cases, and the clinical signs are not highly specific, timely diagnosis is difficult. Delayed verification of the diagnosis and late initiation of adequate treatment are risk factors for multisystem lesions and lead to an unfavorable outcome. The literature describes a few observations of the onset or manifestation of the disease with symptoms of protein malabsorption. We present a rare clinical case of diagnosing histiocytosis from Langerhans cells in a young child with severe manifestations of exudative enteropathy at the onset. The patient's parents gave their consent to the use of their child's data, including photographs, for research purposes and in publications.Refractory gastrointestinal symptoms require mandatory endoscopic and histological examination to identify rare causes of malabsorption. Timely initiation of targeted therapy with vemurafenib in combination with subsequent chemotherapy provided the child with a favorable prognosis and stable remission of the disease.

This article discusses the potential of droplet digital polymerase chain reaction (PCR) for the diagnostic detection and monitoring of the allelic load of the BRAF V600E mutation in circulating cell-free DNA and myeloid progenitor cell population in the bone marrow of patients with Langerhans cell histiocytosis (LCH). Droplet digital PCR may serve as a useful tool for the monitoring of minimal residual disease and improve our understanding of the pathogenesis of Langerhans cells histiocytosis. The study was approved by the Independent Ethics Committee and the Scientific Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology.
A case report of mast cell leukemia in a child and literature review
Authors: Boychenko E. G.
Published: March 2023

Mast cell leukemia (MCL) is a very rare form of aggressive systemic mastocytosis accounting for < 1% of all mastocytosis. Mastocytosis is a broad term used for a group of clonal disorders characterized by accumulation of mast cells in the skin with or without extracutaneous involvement. The clinical spectrum of the disease varies from only cutaneous lesions to highly aggressive systemic involvement such as MCL. Mastocytosis can present from birth to adulthood. In children, mastocytosis is usually benign, and there is a good chance of spontaneous regression at puberty, unlike adult-onset disease, which is generally systemic and more severe. Individuals with systemic mastocytosis may be at risk of developing hematologic malignancies. MCL diagnosis requires the presence of SM criteria with additional features including leukemic infiltration of bone marrow and/or blood by at least 20% high-grade MC as well as the infiltration of extracutaneous organs by neoplastic MC. Genetic aberrations, mainly the KIT D816V mutation, play a crucial role in the pathogenesis of mastocytosis and are detected in most patients. To date, there is no approved standard therapy. For MCL, few options are available for treatment and because of the rarity of the disease very few clinical trials address the question. Even if SM occurs occasionally, all children with mastocytosis require planned follow-up over time. We present an overview of literature on MCL and a rare case of MCL diagnosed in a 4-year-old girl who had had cutaneous mastocytosis since early childhood. A bone marrow examination revealed MCL. She ultimately died despite chemotherapy. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.
