A 65-year old male patient presented to our ophthalmology OPD for regular check up. On examination visual acuity of the right eye was 6/24 improving to 6/12p with pinhole and left eye was 6/18 improving with pinhole 6/9. On examination of anterior segment both eyes cornea showed multiple white round deposits at deep posterior stroma and Descemet membrane – endothelium complex scattered circumferentially in the peripheral cornea and the central cornea clear and lens showed Immature cataract. Fundus examination was within normal limits. A differential diagnosis of stromal corneal dystrophy or endothelial corneal dystrophy was made. By exclusion, we came to the diagnosis of macular corneal dystrophy.
Choroidal neovascularization caused by angioid streaks: seven-year follow-up
Authors: Aliyeva Aygun , Rustambayova Gunay
Published: October 2022

Angioid streaks are irregular lines that radiate away from the optic disc to the retinal periphery, lying deep into the retina. They indicate the breaks in the calcified Bruch’s membrane. The most common complication of angioid streaks is choroidal neovascularization. They appear primarily bilaterally and are asymmetrical in nature.

We report a 29-year-old man with choroidal neovascularization caused by angioid streaks. The study emphasizes seven years of follow-up of the disease treated with intravitreal bevacizumab and aflibercept injections. There were no injection related complications.

Anti-VEGF treatment can help the clinician to stabilize the disease and achieve gradual progression. Nonetheless, it cannot help to prevent significant vision loss in long-term follow-up in all cases.

Las Comunicaciones Nacionales sobre Cambio Climático (CNCC) son un mecanismo para que los países informen sus avances en mitigación y adaptación, y constituyen uno de los elementos de base para la política sobre cambio climático a escala nacional. Colombia ha emitido tres CNCC. La tercera plantea un escenario que considera las proyecciones de diversos modelos incluidos en la quinta fase del Proyecto de Comparación de Modelos Acoplados (Coupled Model Intercomparison Project, CMIP), el cual se estima como el promedio de las proyecciones correspondientes a las cuatro trayectorias de concentración representativa (Representative Concentration Pathways,RCP) presentadas en el quinto reporte de evaluación del Panel Intergubernamental sobre Cambio Climático. Cada una de estas RCP representa una trayectoria de concentración de gases de efecto invernadero (GEI) para un escenario particular de crecimiento poblacional, económico y tecnológico que conduce a una posible trayectoria de evolución del sistema climático. En este estudio se comparan las proyecciones presentadas en la Tercera CNCC con las obtenidas directamente de los modelos empleados. Nuestros resultados demuestran que al utilizarse un promedio de RCP se pierden escenarios alternos que podrían ser importantes a la hora de considerar posibles futuros diferentes y anulan la utilidad de plantear diversas trayectorias de emisiones de GEI. Más aun, una comparación entre la Segunda y la Tercera CNCC muestra proyecciones de precipitación opuestas para diferentes regiones del país, lo cual es de particular importancia, pues el escenario de cambio climático planteado en la Tercera CNCC sirve de referencia para la toma de decisiones en materia de cambio climático a nivel nacional.
Rare-earth ferrobismuthites: ferromagnetic ceramic semiconductors with applicability in spintronic devices

Published: October 2022

We report here the synthesis process of the perovskite-like complex material Bi0.5R0.5FeO3 (R=Eu, Sm, Dy) using the ceramic method, as well as its structural, optical, magnetic, and electrical characterizations. Refined X-ray diffraction data revealed that this material crystallizes in an orthorhombic structure (space group Pnma number 62). The band gap value in the optical response shown in the diffuse reflectance spectroscopy curve was typical of semiconductor materials. The magnetization exhibited a very low coercive field hysteretic behavior, which is characteristic of weak ferromagnetism, for all temperatures examined below 300 K and the various magnetic fields applied. The real and complex electric permittivity curves showed the occurrence of dielectric relaxation processes at 113 K in agreement with reports of pyroelectric and thermo-stimulated currents as a function of temperature revealing the appearance of ferroelectric polarization below 113 K with possible magnetoelectric coupling. On the other hand, we made a theoretical study of the electronic structure with and without the inclusion of a Berry distortional phase and ab-initio calculations following the density functional theory formalism and the pseudopotential plane wave method. In this formalism, the exchange and correlation mechanisms are described by the generalized gradient approach (GGA + U) considering spin polarization. The Berry phase analysis suggested the occurrence of ferroelectricity at temperatures below 113 K consistent with the experimental analysis evidencing a biferroic behavior at low temperatures given that the distortional phase introduces hybridizations between the 3d-Fe and 2p-O states favoring the appearance of Dzyaloshinskii-Moriya interactions, which, in turn, facilitate the appearance of ferroelectricity coexisting with a weak ferromagnetism. The thermodynamic properties in the presence or absence of the Berry phase by means of the Debye quasiharmonic model revealed the appearance of a ferroelectric transition at 113 K, which corroborates their magnetoelectric nature at low temperatures. The ferromagnetic semiconducting character found at room temperature enhances this material for applications in spintronics technology.

The THEMA tool to support heritage-based development strategies for marginal areas
Authors: Rossitti Marco , Torrieri Francesca
Published: October 2022

The ongoing forced reflection on the leading urbanization models' crisis has led to greater attention to marginal areas. In Italy, the scientific and media debate has focused on inner areas that, since 2014, have represented the target of an innovative national cohesion policy aimed at tackling their shrinking dynamics: the National Strategy for Inner Areas (SNAI). Indeed, Italian inner areas are endowed with extraordinary natural capital and settlement models far from urban density. Thus, they seem to respond perfectly to the new raised living needs.
However, leaving aside the optimistic rhetoric, strong political and administrative choices are necessary to trigger a `return process' based on this broader attention toward inner areas, thus countering humankind's natural tendency to concentrate on urban realities.
In this light, the paper proposes a tool to support SNAI in designing and implementing heritage-based local development strategies to address inner areas' real needs. After a critical reading of the new challenges for planning posed by the pandemic and SNAI's role within them, the contribution moves to frame the THEMA (Tool for Heritage-based Enhancement of Marginal Areas) tool, focusing on specificities of the inner areas as cultural heritage. Finally, the tool's application to a case study, an inner area in Campania Region, allows to outline and discuss its possible benefits for SNAI implementation and its limits.

Objective: N-Methyl D-Aspartate (NMDA) receptor blockers have been shown to have protective effects against ischemia/reperfusion (I/R) injury in various tissues. The aim of this study was to investigate the effects of 90 ve 135 mg/kg doses of amantadine on lung in hepatic I/R injury.

Method: The rats were randomly divided into six groups: Group Sham, Group I/R, Group Amantadine-90, Group Amantadine-135, Group I/R-90 and Group I/R-135. In I/R, an atraumatic vascular clamp was applied to the structures in the left portal triad for 45 minutes and reperfusion period was 2 hours after ischemia. Malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) enzyme levels were performed the lung tissue and tissues were examined histopathologically.

Result: A significant difference was found between the groups in terms of MDA, SOD, CAT levels (respectively; p < 0.001, p=0.008, p < 0.001). A significant difference was found between the groups in terms of lung tissue neutrophil/lymphocyte infiltration scores and alveolar wall thickening scores (respectively p=0.009, p=0.002).

Conclusion: The biochemical and histopathological results of the present study suggested that amantadine, like other NMDA antagonist agents, may have a protective effect on lung tissues against the damage caused by hepatic I/R injury. Although we observed significant improvements after the administration of both doses studied, there was no significant difference between these two doses in terms of their success in protecting against distant organ lung injury. Amantadine appears promising as a therapeutic agent in treatment.

Web 2.0 at the Heart of Myanmar’s Turmoil
Authors: Gorombolyi David
Published: October 2022

As digitalization has transformed arguably all aspects of human existence and co-existence, it has obviously made its way into the realms of politics, diplomacy and the dynamics of emerging social tendencies on all levels – global, regional and local. This study takes a look at how Web 2.0 has affected Myanmar’s public conflicts during the last two decades – and does so from the standpoint of social sciences, examining the unique nature of Burmese online development compared to other parts of the world, analyzing the interrelated nature of civil and government actions in the virtual sphere and on the streets alike. Looking at the related details of recent and partially ongoing social tragedies of Myanmar, this paper shows both how deeply Web 2.0 can infiltrate offline reality, and how obvious its limits are still in the hands of humans.

It is generally believed that a global education crisis occurs within the health care occupations. There are several reasons that cause this condition, such as the discrepancy between educational systems and basic needs of the health care system, the rapidly-changing, complicated and dangerous environment (e.g., The COVID-19 pandemic) the problems with the disability of applying students’ theoretical knowledge in a harmless clinical environment, especially in the condition of mentor’s scarcity. At least – out of date system of medical education, where the emphasis is on getting knowledge and not its practical application. The article concerns our viewpoint and the ways, medical education can be improved upon in Georgia.

Published: October 2022

This study was conducted to determine the antifungal potential of plants traditionally used in the treatment of infections. Five (5) plants were collected. The anti-candida albicans activity was evaluated by the double dilution method in tilted tubes with the aqueous and hydroethanolic extracts of the different plants. The results showed that the 70% ethanolic extracts were more active than the aqueous extracts for all plants. The 70% ethanolic extract of T. ivorensis (FMC = 1.56 mg/ml) was the most active on the tested strain. It was followed by T. superba (MFC = 3.125 mg/ml) D. benthamianus (MFC = 50 mg/mL), G. arborea (MFC= 50 mg/mL) and J. secunda (MFC ˃ 50 mg/mL). The phytochemical screening revealed the presence of seven major groups of compounds, among which saponins and catechins are the most abundant in the aqueous extracts. Polyphenols, Flavonoids, Polyterpenes and Sterols as well as Tannins are equally present in the alcoholic and aqueous extracts of the different plants at variable levels. These compounds could justify its activity and its traditional use.

Published: October 2022

Below-average performance is a characteristic that has been synonymous with many county governments in Kenya. The counties, formulate a County Integrated Development Plan as a guiding roadmap for five years. Besides the well-formulated strategies in Meru County, performance and effective service delivery have not been satisfactorily achieved. This study was designed to investigate strategy implementation and performance of the Meru County Government. The study’s specific objectives were; to determine the effects of resource allocation, organizational culture, leadership, and organizational structure on strategy implementation and performance of Meru County Government. The study targeted 291 employees of Meru County Government and a descriptive research design was used. Multiple regression analysis was used to analyze data. Findings indicated that resource allocation, organizational culture, leadership, and organizational structure had a positive and significant influence on the county government’s performance. The study recommends that; on resource allocation, the county government prioritize sufficient resource allocation on matters of strategy implementation, and create a wide and growing resource base to properly finance its activities. In organizational culture; mission and goals should be made clear at every level, and the culture should uphold goal attainment and promote easy communication during strategy implementation. In organizational leadership, the study recommends that the management should have more employees contribute to decision-making. Periodic workshops and/or training should be held for all employees. On the organizational structure; the county government can enhance its structure through participative decision-making, creating a simple and short chain of command for strategy implementation and promoting interdepartmental learning.

La Traite Cacaoyère à L’épreuve de L’insécurité dans la Sous-préfecture de Soubré (Sud-ouest Ivoirien)
Authors: St Urbain Yeboue Konan Thiéry
Published: October 2022

Le cacao représente 10 à 15% du Produit Intérieur Brut (PIB) de la Côte d’Ivoire, avec près de 40% de ses recettes d’exportation. Il est la principale source de revenus de près de 800 000 ménages de producteurs. Cependant, le secteur cacaoyer ivoirien est confronté à de nombreux problèmes qui constituent des pesanteurs à son bon développement. Cet article, mené à l’échelle du territoire de la sous-préfecture de Soubré (sud-ouest de la Côte d’Ivoire), analyse la traite cacaoyère et sa pesanteur majeure qu’est l’insécurité causée par les actes criminels. Il s’appuie sur une recherche documentaire et une enquête de terrain auprès d’acteurs tels les producteurs, les coopératives et les forces de sécurité. Il est fondé sur une théorisation de l’environnement sécuritaire de la traite cacaoyère pour aboutir à trois principaux résultats. Ces résultats indiquent d’abord que la traite cacaoyère cristallise essentiellement deux types de flux, impulsés par les activités des acteurs. Ensuite, des facteurs divers concourant à l’installation d’une atmosphère d’insécurité. Enfin, d’une campagne à l’autre, les actes d’infractions connaissent une évolution en fonction de l’intensité des activités commerciales autour de la production du cacao.

Published: October 2022

La végétation de la région de l’Ouest est essentiellement composée de savane, dont la savane arborée, qui est prédominante, constitue la principale source de bois d’énergie de cuisson des ménages. La présente étude a pour objectif d’analyser l’apport des foyers améliorés sur la préservation de la végétation à l’Ouest Cameroun. Afin d’évaluer cette contribution, l’on a en premier lieu réalisé une analyse spatiale, décrivant l’état de la végétation dans cette région, et en second lieu, évalué l’apport de l’usage des foyers améliorés sur la protection de la savane. L’étude indique qu’entre 2005 et 2015, la superficie de la savane a régressé de 818 300 hectares (8 183km2), du fait de la pression humaine. Cette régression serait ainsi en partie contenue, si une substitution d’un foyer à trois pierres par un foyer amélioré était réalisable au sein de chaque ménage. Celle-ci conduirait à une économie de 1 648Kgs de bois par ménage par an, correspondant à une superficie de 15 614,8 hectares de savane préservée par an.
Etat des Lieux de L’architecture et de L’urbanisme Bioclimatique dans L’aménagement Urbain de la Ville de Lomé au Togo
Authors: Akouété Atsou Fiéfonou , Banon Fabrice
Published: October 2022

La ville de Lomé connait depuis plus de quatre décennies une urbanisation relativement galopante qui paralyse sa durabilité. Les pratiques de construction constituent un axe important de lecture de cette entrave à la durabilité. En effet, l’on constate que la majorité des projets d’aménagement urbain de la ville de Lomé prennent des formes hétéroclites avec un mimétisme à outrance de l’aménagement urbain des villes européennes et celles des autres continents. L’on se pose alors la question de savoir en quoi les pratiques architecturales et urbanistiques de construction qui ne sont pas forcément endogènes peuvent entraver la durabilité urbaine. Pour appréhender la question, la posture méthodologique est transdisciplinaire et encré dans l’approche qualitative. Il ressort suivant une analyse chronologique que, avant et pendant la colonisation l’architecture et l’urbanisme de ces périodes prennent en compte, l’aménagement bioclimatique. Toutefois, les pratiques de construction après les années 1960 sont peut respectueuses de l’environnement et ne respectent pas les principes de l’urbanisme et de l’architecture bioclimatiques. Ces pratiques compromettent la durabilité urbaine dans la ville de Lomé.

Published: October 2022

Le bassin versant de Ogo est touché par les aléas climatiques et fait face à des défis écologiques et environnementaux considérables (montée de la désertification). Les terres agricoles sont devenues de plus en plus fragiles du fait de l’érosion hydrique. Dans cet article, la morphodynamique hydrique est étudiée par des mesures de terrain à différents sites sur des parcelles d’expérimentation. Les mesures sur les parcelles d’érosion entre 2015 et 2017 ont montré une forte variabilité des taux de ruissèlement et d’érosion entre les sites observés. Cette variabilité est liée à la pluviométrie et au type de sol. Les coefficients de ruissellement varient entre 0,8 et 0,25 sur les sites d’observation (Thiankone Hiraye, Mbélone et Danthiady). L’érosion sur les parcelles sont estimées à 18,7 tonnes par hectares en 2015, 13,4 t/ha en 2016 et 14,95 t/ha de pertes en terre en 2017.
Role of Strategic Investment Approaches on Efficient Performance of Real Estate firms in Kenya
Authors: Achieng Olivia Adhiambo , Mule Robert Kisavi , Aila Fredrick Onyango
Published: October 2022

Resources like time, organizational efforts and materials require efficient management in order to achieve greater outputs. Every organization need to reduce waste in these resources to the minimum possible so as to produce high quality services and products. The real estate industry has been evolving overtime from the traditional conventional bricks and mortar industry to be more dynamic and operational, focusing on access and outcomes rather than ownership. Investors who do not develop creative and cost-effective strategies of accessing operational experience and innovation are likely to have diminishing returns on their investments. This paper illustrates how efficiency in operations is influenced by how investors select a combination of their investment portfolio. The study reviews and analyses the concept of operational efficiency of real estate investment firms in Nairobi county and suggests ways in which it can be improved in future through strategic decision making. This article sought to establish the effect of strategic investment approaches on efficient performance of real estate investment firms in Kenya, the study period being 2018-2022. Strategic investment approaches were the independent variable and efficient performance the dependent variable thus analyzing the relationship between the two variables. Theoretical literature links strategic investment approaches to investment performance both positively and negatively with some scholars stating that there is a positive relationship between the two while other scholars contradicting. Correlational survey design and census sampling method were used to draw 231 registered real estate investment firms in Kenya's capital city of Nairobi. Primary data was gathered using structured questionnaires to collect data from 231 operations managers and analyzed by regression analysis. The findings of the study indicated that strategic investment approaches is positively correlated to efficient performance at (p<0.05) and R² of 60.3% indicating that 60.3% change in efficient performance is caused by strategic investment approaches while 39.7% will be explained by other factors. The study revealed that strategic investment approaches is a strong driver of operational efficiency thus recommends that the firm’s strategic intelligence teams should proactively integrate strategic innovation and move away from the old ways of creating and managing real estate.

Vietnam is in the process of implementing education reforms in which teachers play a crucial role in determining success. This study aims to identify the main factors influencing the perception of happiness at work of Vietnamese teachers during the period of educational reform. In any period, teachers are always considered as being the force behind the success of education. Therefore, teachers' happiness is the most vital factor to be taken into consideration when educating students. Identifying the factors that affect teachers' happiness at work is the key to improving their teaching quality and quality of life. This study was conducted to investigate the factors affecting the perceived happiness of secondary school teachers in Vietnam today, thereby objectively assessing the emotional status of teachers in Vietnam in relation to the work they are doing. The results are as follows: 1) Teachers face a lot of pressure from many sides; 2) There is still a large percentage of teachers who do not really attach importance to the teaching profession; 3) State policies have not helped teachers feel secure in their professional activities; 4) Teacher capacity still needs to be greatly improved; 5) It is necessary to strengthen the connection between teachers, educational leaders, policy makers, school administrators and colleagues. This study uses descriptive statistics to present the research results. The survey was carried out in September 2021.

Background: High sodium consumption is one of the risk factors for hypertension. Excess salt intake may be affected by an individual’s ability to detected taste. However, decreased salt sensitivity can increase consumption of salty foods. Purpose: This review aims to analyze the salt taste threshold and its relation to salt intake among hypertensive and normotensive individuals. Methods: The review was conducted using five electronic databases and fourteen articles reporting on salt taste threshold, salt intake, and blood pressure. Open access articles, original research, published over the past ten years, and subject’s age over eighteen years both healthy and with specific clinical conditions, and have blood pressure data were identified and included in the study. Results: There were fourteen studies that measured salt taste threshold through detection threshold and/ or recognition threshold. Ten studies reported salt consumption through Na-FFQ, SQ-FFQ, 24-hour food recall, discretionary salt, adding salt questionnaire, salt use behavior questionnaire, salt preference questionnaire, and sodium excretion. Most studies showed that high salt consumption is higher in the group with high salt taste threshold and high salt taste threshold tends to be more in hypertensive group. The result also showed a significant correlation between salt consumption both through self-reported questionnaire and 24-hour urinary sodium excretion. Conclusion: Although the correlation between salt taste threshold, salt intake, and hypertension can be found a matching method with adequate statistical power is needed to get more accurate results.

Background: The condition of failure to thrive in toddlers due to chronic malnutrition and making children too short for their age is called stunting. Purpose: This research was conducted to analyze the risk factors of stunting in children.  Methods: The study was conducted from mid-May to mid-August 2020. This study developed a model for maternal empowerment in preventing and managing stunting using a cross-sectional design, then implementing the model using a quasi-experimental non-randomized pre-post control group design. The population involved was all mothers with children under five years old in Posyandu Ngariboyo, Candirejo, and Plaosan, obtaining 250 mothers. Meanwhile, the study sample was 150 mothers who had children under five years old in Posyandu Ngariboyo, Candirejo, who met the inclusion criteria. Results: Mothers with good characteristics increased their knowledge of stunting prevention and control by 0.42 times (p=0.01). Mothers with good knowledge increased their maternal commitment by 0.23 (p=0.01), and mothers who had good commitment reduced stunting by 0.45 (p=0.01). Furthermore, mothers with good knowledge increased the family support by 0.24 (p=0.01). In addition, good family support also reduced stunting by 0.26 (p=0.01). Conclusion: Mother's knowledge contributes to the prevention and management of stunting. Children's physical health, family support, nutritional status, and home environment are also important factors in stunting prevention and management. Family support is needed by mothers to realize their commitment to carrying out early detection, prevention, and control stunting.

Depression and anxiety are common in cancer patients due to metabolism alteration and the side effects of chemotherapy. These mental health problems could be even worse in patients with low economy status and living in shelter houses. The aim of the research was to analyze the relationship of anxiety, depression, and macronutrient intake with nutritional status in cancer survivors undergoing chemotherapy at shelter houses. A total of 42 cancer patients aged 40-60 years old at shelter houses was recruited using consecutive sampling under a cross-sectional study design. Anxiety and depression data were taken using the Hospital Anxiety and Depression Scale (HADS) questionnaire, while energy, protein, fat, and carbohydrate data intakes were using Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ). The nutritional status data was examined based on Mid Upper Arm Circumference (MUAC). The data were analyzed using Pearson and Rank Spearman tests. Results of the study indicate that there were significant relationships between energy (p=0.040; r=0.318) and fat (p=0.001; r=0.490) with nutritional status. However, there was no relationship between anxiety and depression with macro-nutrient adequacy; also protein and carbohydrate intake with nutritional status. Anxiety and depression with nutritional also did not relate as evidenced by the value (p>0.05). To sum up, although there were no correlations between anxiety and depression with nutritional status, correlations occurred between energy and fat with nutritional status. Further research is suggested to analyze variables underlying anxiety and depression such as family support, stage, duration of diagnosis and frequency of chemotherapy so that these variables can be controlled.
DOES EMOTIONAL EATING MEDIATE THE EFFECT OF PHYSICAL ACTIVITY AND SLEEP DURATION ON FAT INTAKE IN PREGNANT WOMEN?
Authors: Fariandini Aisyah , Fanani Mohammad , Mulyani Sri
Published: October 2022

Pregnant women need nutrients, one of which is fat. High fat intake might occur due to emotional eating. Emotional eating and excessive fat intake are assumed to be caused by low physical activity and insufficient sleep duration. This study purposed to investigate whether emotional eating mediates the effect of physical activity and sleep duration on fat intake in pregnancy. This study used an analytic survey method with a cross-sectional approach. The population of this study was pregnant women in the second and third trimesters who lived in Bondowoso Regency. Sampling was conducted with a cluster random sampling technique, and 105 subjects were obtained. The research instruments included a 24-hour food recall form, Emotional Eater Questionnaire (EEQ), Pregnancy Physical Activity Questionnaires (PPAQ), and four sleep duration questions from the Pittsburgh Sleep Quality Index (PSQI) form. Statistical test used path analysis. The direct influences in this study were shown by the variables of physical activity and sleep duration on emotional eating (p-values 0.027 and <0.001), and emotional eating on fat intake of pregnant women (p-value <0.001), respectively. Emotional eating can explain the effect of physical activity and sleep duration on fat intake with the indirect effect value greater than that with the direct effect. The conclusion of this study is that there is a role for emotional eating to mediate the indirect effect of physical activity and sleep duration on fat intake. Women who are pregnant should be able to do dietary habit, regulate sleep, and physical activity.

Stunting or chronic undernutrition is a consequence of a lack of nutrition for a long time. Stunting is still a main isu in developing countries such as Indonesia. According to SSGBI 2021, the prevalence of stunting in Indonesia was decreased from 2019 to 2021 that is 27,67% to 24,4%. Government has many programs to decrease stunting. Thus, research that can present facts comprehensively about stunting prevention program is needed to make policies regarding the precise and efficient program. The research aims to identify stunting prevention program in Indonesia. This research used a systematic review method arranged based on Preferred Reporting Items for Systematic Reviews and MetaAnalyzes (PRISMA). Five databases are used for searching articles that are PubMed, Google Scholar, Portal Garuda, Perpustakaan Nasional (Perpusnas) Indonesia, and ScienceDirect. Research inclusion criteria are articles were published from 2011 to 2020 with the population in Indonesia. For articles assessing quality we used The Joanna Briggs Institute (JBI) Critical Appraisal. Form 15 articles we found that effective program for preventing stunting is nutrition education for influential parties (cadre, children’s mother, pregnant women, and mother to be), establishing a study group for children’s mother, and supplementary feeding for children. Stunting prevention program must be paying attention to input and process aspects for better outputs and must involve all parties from children’s mothers to cross-sectoral.

Tumor vaccines, a type of personalized tumor immunotherapy, have developed rapidly in recent decades. These vaccines evoke tumor antigen-specific T cells to achieve immune recognition and killing of tumor cells. Because the immunogenicity of tumor antigens alone is insufficient, immune adjuvants and nanocarriers are often required to enhance anti-tumor immune responses. At present, vaccine carrier development often integrates nanocarriers and immune adjuvants. Among them, outer membrane vesicles (OMVs) are receiving increasing attention as a delivery platform for tumor vaccines. OMVs are natural nanovesicles derived from Gramnegative bacteria, which have adjuvant function because they contain pathogen associated molecular patterns. Importantly, OMVs can be functionally modified by genetic engineering of bacteria, thus laying a foundation for applications as a delivery platform for tumor nanovaccines. This review summarizes 5 aspects of recent progress in, and future development of, OMV-based tumor nanovaccines: strain selection, heterogeneity, tumor antigen loading, immunogenicity and safety, and mass production of OMVs.

Published: October 2022

This paper presents the development and implementation of a machine learning model to estimate the future price of commodities in the Brazilian market from technical analysis indicators. For this, two databases were obtained regarding the commodities sugar, cotton, corn, soybean and wheat, which were submitted to the steps of data cleaning, pre-processing and subdivision. From the pre-processed data, recurrent neural networks of the long short-term memory type were used to perform the prediction of data in the interval of 1 and 3 days ahead. These models were evaluated using mean squared error, obtaining an accuracy between 0.00010 and 0.00037 on the test data for 1 day ahead and 0.00015 to 0.00041 for 3 days ahead. However, based on the results obtained, it can be stated that the developed model obtained a good prediction performance for all commodities evaluated.

In this paper numerical simulation of the spectral properties of xenon plasma is carried out for various parameters (temperature, density, pressure) within the framework of the Saha-Boltzmann approximation. For calculations, pre-prepared atomic databases with varying degrees of detail of ion states were used. The effect of ionization potential depression was taken into account. The spectral absorption coefficients and emissivity, as well as the spectral radiation energy flux for a homogeneous plasma in a spherically symmetric geometry, were obtained. The identification of strong spectral lines in the wavelength ranges of interest has been carried out.

Authors: Shinegi Diomi , Widjaja Anton Wachidin
Published: October 2022

The development of sharia hotels is considered as a support for tourism that is not only commercially oriented but always upholds the noble values of religion and customs of a nation. This study is a quantitative study that aims to test the influence of independent variables on dependent variables. The sample in this study was carried out by simple random sampling. The research data was obtained by spreading questionnaires to sharia hotel customers. The collected data were analyzed by path analysis assisted by the Smart PLS application. Smart PLS analysis in this study was carried out in 2 stages, namely outer model and inner model analysis. Inner model analysis for 1) testing the validity and reliability of the instrument and 2) conducting an r square test to determine the percentage of influence. The inner model analysis is carried out to test hypotheses. Based on the test results, it is known that all instruments are declared valid and flexible. Hotel Interior, Hotel Customer Process, and Hotel Design affect customer satisfaction by 94.0%, while Hotel Customer Process and Hotel Design affect customer satisfaction and customer satisfaction affects repurchase intention by 96.1%. The results of hypothesis testing show that the Hotel Customer Process, Hotel interior, and hotel design affect the company's satisfaction, and customer satisfaction can partially mediate the relationship between the hotel customer process, hotel interior, and hotel design to repurchase intention. Upcoming research is expected to add other variables because there are still many factors that affect consumer satisfaction and repurchase intentions of Islamic hotel customers. The reach for research on Islamic hotels can expand and expand widely.
