Las Áreas Naturales Protegidas (ANPs) constituyen la principal estrategia para la conservación de la biodiversidad en Colombia y en el mundo. Una de las formas de evaluar la efectividad y el impacto de las ANPs es a través de las especies que protegen, especialmente de aquellas especies cuyas poblaciones están en declive (amenazadas). El objetivo de este trabajo fue evaluar la riqueza de especies de vertebrados amenazados y endémicos amenazados dentro de las ANPs de la región Pacífico de Colombia, así como describir las zonas de mayor riqueza de especies en la región. Usando información disponibilizada por la UICN y Birdlife-International, se diseñaron mapas de riqueza de especies a nivel general y a nivel de grupo biótico. Encontramos que más del 80 % de las especies de vertebrados amenazados y endémicos amenazados se distribuyen dentro de las ANPs de la región Pacífico de Colombia. Se sugiere que las ANPs del Pacífico colombiano cumplen un rol fundamental para la conservación de especies amenazadas de la región. Se presentan implicaciones de los resultados obtenidos en términos de los acuerdos internacionales a los cuales Colombia está subscrita, así como algunas recomendaciones para futuros estudios relacionados.
Total Cinema, Total Theatre, Total World: From Set as Architecture to Set as Virtual Performer
Authors: Gottwald Dave
Published: December 2022

Sets are a construction within André Bazin’s “recreation of the world in its own image.” During the 1920s, advances in film stock (which improved image clarity) and better lenses (which expanded depth of field) meant that the visual fidelity of sets had to increase. Most critical was more sophisticated camera motion. Cranes could now take the camera into sets, which required more complete environments. Sets have mutated and spread ever since. Architects began working in the movie industry and movie people began working as architects. With the introduction of the first Disney theme park, this practice became codified and thematic placemaking has since proliferated globally. Sets later provided the blueprint for digital games, and as embodied in the game engine have reached virtual holism. Today, Industrial Light & Magic’s StageCraft pairs LED display walls with game engine technology on a soundstage called the Volume. StageCraft replaces both CGI and the traditional set with mixed reality, photorealistic digital environments. Filmmakers can also make design changes in real time and move these virtual backgrounds around the players. This article posits a new history of the spatial philosophy of set design in which the experiential mode of themed spaces, video games, and virtual reality each become a unified recombination of Bazin’s rigid theatre/ cinema dichotomy.
Introduction : Total Cinema: Film and Design
Authors: Bakk Ágnes Karolina , Gyenge Zsolt , Horváth Olivér
Published: December 2022

The movie screen is up in flames and the audience flees in panic, thinking an atomic bomb has just been dropped. The director rubs his hands: film and the outside world have blended into one—at least in Joe Dante’s Matinee (1993), set in the 1962 Cuban Missile Crisis. May this be the “myth of total cinema” described by André Bazin in 1946, according to which the art of film was never really driven by its accidental technological history but by a desire to grasp reality in its entirety, to reconstruct “a perfect illusion of the outside world in sound, color, and relief”? Dante’s larger than life director pays homage to B-movie showman William Castle, who shied away from little when it came to engagement, be it narrative, visual, or somatic. Castle appeared on screen offering the audience a (faux) choice between alternative endings, used 3D illusionism, and installed “buzzers” in the seats and skeletons flying over the auditorium—not unlike Eisenstein’s Proletkult theatre which included tightrope-walkers over the viewers’ heads and firecrackers under their bottoms. Is it possible to unite the effects of agitprop theatre, the illusion of agency in American trash films and the immersive formats of our time into a single conceptual framework? And if it is, would that be cinema? Film theorist Andrew Dudley already claimed in 1997 that “[t]he century of cinema offered a fragile period of détente during which the logosphere of the nineteenth century with its grand novels and histories has slowly given way—under the pressure of technology, of the ascendance of the image, and of unfathomable world crises—to the videosphere we are now entering.”
Remanences and Futurities : Jonathan Rozenkrantz: Videographic Cinema
Authors: Török Ervin
Published: December 2022

Jonathan Rozenkrantz’s book, Videographic Cinema analyses the now obsolete medium of video from a refreshing and exciting perspective. The book focuses primarily on the emergence of analogue video images in theatrically released feature films. Rozenkrantz’s approach to the archaeology of video images is carefully balanced between the refusal of ontological idealism on the one hand (exemplified by works of André Bazin and D. N. Rodowick, among others), and on the other, the refusal of the reduction of video images to mere textual signifiers.
Domain Structure Formation in Designing of the Opened Informative Measuring Systems
Authors: Knyazev M. A.
Published: December 2022

The opened systems possess an increasing significance and possibilities of applying in designing of measuring devices. Now an essentially nonlinear models are used for such systems. The perturbation approach is not enough for these purposes. Models of new types have solutions in a form of soliton or kink and similar objects. The equation of Fisher–Kolmogorov–Petrovskii–Piskunov is one of such equations. This equation is used for description of convection-reaction-diffusion processes. Such processes are used for studying of a self-organisation and formation of a structure in non-equilibrium opened systems. The aim of this work was to construct of a new solution for the modified equation of Fisher–Kolmogorov– Petrovskii–Piskunov in which a space inhomogeneity is accounted.To solve this problem the direct Hirota method for nonlinear partial differential equation is applied.Some modifications into this method were introduced.The new topologically non-trivial solution of the modified Fisher–Kolmogorov–Petrovskii–Piskunov equation is constructed explicitly. This solution has a kink-like form. Some arguments on the stability of such solution are considered.A possibility of domain structure formation in the systems which describe by the Fisher–Kolmogorov– Petrovskii–Piskunov equation is demonstrated.
Concept of Vector Multicomponent Physical Quantities, Models and Measurement Method
Authors: Nesterov V. N.
Published: December 2022

The paper presents a new view of vector physical quantities as multicomponent quantities. Each of the components of the mentioned multicomponent quantities can carry important and even unique information about the sources and causes of their occurrence. Looking at the vector quantity as the multicomponent quantity led to the need to form the corresponding conception. There are three positions of this conception in this paper, which are formulated as follows: vector multicomponent physical quantities are considered as functions of the set of their constituent information components; the communication functions of the specified information components in the models of multicomponent physical quantities are determined by the laws of vector algebra; information models of vector multicomponent physical quantities allow an alternative representation of information components depending on the selected coordinate system.

The mathematical model of the vector multicomponent physical quantity is presented. This model is fundamental and directly follows from the positions of the conception formulated above. This model can be applied to describe multicomponent displacements and deformations that both simple and complex objects undergo. An example of the complex object can be the manipulator of the universal industrial robot. The space for modeling multicomponent displacements of simple objects was shown in the paper. Information models of vector multicomponent physical quantities allow one to alternatively represent informative components. And the task of constructing such models is complex and ambiguous. Therefore, the formal apparatus for the synthesis of such models, which is based on certain rules and conventions, was proposed in the paper. The theoretical foundations of the method of optical measurements of informative components of multicomponent displacements and deformations of simple objects, which involves the use of multidimensional test objects, are presented.
Application of Waves with Circular Polarization in Magnetotelluric Sounding
Authors: Plotkin V.V. , Pospeeva E.V. , Potapov V.V.
Published: December 2022

—We consider the possibility of using circular polarizations, which make the field vector in a wave rotate clockwise or counterclockwise, as independent polarizations of the primary wave during magnetotelluric sounding (MTS). This approach has been proposed for the first time to search for possible manifestations of the Hall effect under natural conditions during MTS; in this case, if the effect is small, waves with circular polarization become normal modes in a horizontally layered medium located in the constant magnetic field of the Earth. Standard impedance relations are replaced by the corresponding apparent resistance impedances and curves for waves with circular polarization (mode). In the search for manifestations of the Hall effect during MTS, it becomes necessary to determine differences in the mode apparent resistivity curves due to the presence of lateral inhomogeneities of the medium. This study deals with the specific features of MTS in the case of representing the primary source field by circular polarization waves. Results of the theoretical analysis of mode impedances are demonstrated. Numerical simulation is used to investigate the differences in the mode impedances and curves depending on the nature of the distribution of lateral inhomogeneities in the medium. Mode apparent resistivity curves obtained by processing the experimental data of the MTS in Gorny Altai are presented. It is shown that, in comparison with standard curves, mode curves are subject to less distortion by lateral inhomogeneities of the medium owing to the specific features of distributions of the charges and currents excited by circular polarization waves in them.

Published: December 2022

La trashumancia es una práctica ganadera ancestral que lucha por pervivir mientras se apuntala su consideración como patrimonio inmaterial. Su conocimiento en el ámbito universitario se ha ceñido tradicionalmente a los estudios de veterinaria, pero las implicaciones culturales y patrimoniales que subyacen en la misma hacen que pueda ser foco de atención de otras áreas. Ello es lo que se pretende demostrar en el presente trabajo, donde se analizan los resultados de una propuesta práctica, basada en la conjugación de metodologías cuantitativas y cualitativas, desarrollada para vincular con el patrimonio de esta actividad los contenidos teóricos de la asignatura de “Patrimonio Cultural” del Grado en Ciencia y Tecnología Geográficas de la Universidad de Murcia. Las conclusiones obtenidas han puesto de relieve que impulsar ejercicios sostenidos en la educación patrimonial facilita la comprensión y aplicación de las competencias que un futuro geógrafo debe dominar en este campo de trabajo.
An Integrated Multi-modal Learning Method for Early-stage Knee Osteoarthritis Disease Classification
Authors: Liu Liangliang , Chang Jing , Ma Qingzhi
Published: December 2022

Background: Osteoarthritis (OA) is a progressive and chronic disease. Identifying the early stages of OA disease is important for the treatment and care of patients. However, most state-of-the-art methods only use single-modal data to predict disease status, so that these methods usually ignore complementary information in multi-modal data.
Methods: In this study, we develop an integrated multi-modal learning method (MMLM) that uses an interpretable strategy to select and fuse clinical, imaging, and demographic features to classify the grade of early-stage knee OA disease. MMLM applies XGboost and ResNet50 to extract two heterogeneous features from the clinical data and imaging data, respectively. And then we integrate these extracted features with demographic data. To avoid the negative effects of redundant features in a direct integration of multiple features, we propose a L1-norm-based optimization method (MMLM) to regularize the inter-correlations among the multiple features.
Results: MMLM was assessed using the Osteoarthritis Initiative (OAI) data set with machine learning classifiers. Extensive experiments demonstrate that MMLM improves the performance of the classifiers. Based on MMLM, the accuracy of SVM and DT are 83.45% and 81.27%, respectively, which are much higher than other feature fusion method. In addition, the visual analysis of the important features in the multi-modal data verified the relations among the different modalities.
Conclusion: MMLM uses the internal correlations among different modalities to enhance the efficiency of feature extraction and fusion, which improves grade classification of early-stage knee OA.

Design and Implementation of Elliptical Mantle Cloaks for Polarization Decoupling of Two Tightly Spaced Interleaved Co-Frequency Patch Array Antennas
Authors: Masoumi Reza , Kazemi Robab , Fathy Aly E.
Published: December 2022

In this paper, the method of mantle cloaking is utilized to decouple/isolate two densely interleaved patch array antennas operating at the same frequency but with orthogonal polarizations. To reduce the mutual coupling between the adjacent elements, vertical strips, as a type of elliptical mantle cloaks, are located at close proximity to the patches. At the operating frequency of f0 = 3.7 GHz, the edge-to-edge spacing of the elements of the two interleaved arrays is less than λ0/80 (1 mm) and the center–to-center spacing of each array elements is 0.7 λ0 (57 mm). The proposed design is implemented using 3D printing technology, and its performance in terms of return loss, efficiency, gain, radiation patterns, and isolation is measured for evaluation. The results show the radiation characteristics of the arrays are perfectly retrieved after cloaking similar to the isolated arrays. Decoupling of tightly spaced patch antenna arrays on a single substrate paves the way to achieve miniaturized communication systems with full duplex operation or dual polarization communication.

Molecular diodes are of considerable interest for the increasing technical demands of device miniaturization. However, the molecular diode performance remains contact-limited, which represents a major challenge for advancement of rectification ratio toward commercial availability. Here, we demonstrate that high-quality ultrathin organic semiconductor can be grown on several classes of metal substrates via solution-shearing epitaxy, with well-controlled number of layers and monolayer single crystal over 1 mm. The crystalline films are atomically smooth and free pinhole, providing a native interface for high-performance molecular diodes. As a result, the molecular diodes show record-high rectification ratio up to 5 × 108, ideality factor close to unity, aggressive unit conductance over 103S/cm2, reverse breakdown electric field～1.1 × 108V/cm, excellent electrical stability and well-defined contact interface. We further fabricate large-area molecular diode arrays with 100% yield and excellent uniformity in the diode metrics. Our results suggest that monolayer crystalline films have great potential to build reliable, high-performance molecular diodes and deeply understand their intrinsic electronic behavior.

Published: December 2022

[Purpose] Inflammatory bowel disease (IBD) is closely related to stress and fatigue. Human herpesvirus 6 (HHV-6) is reactivated by stress and fatigue and associated with IBD. This study aimed to clarify the relationship between IBD and HHV-6.
[Methods] Antibody titers to SITH-1, a protein specific to HHV-6 latent infection, were measured in 163 patients with IBD (107 with ulcerative colitis [UC] and 56 with Crohn's disease [CD]); clinical scores and depression scores of UC and CD were analyzed to examine the relationship between SITH-1 and IBD.
[Results] In patients with UC, CRP level was significantly higher (1.5 mg/L vs. 0.3 mg/L; P = 0.006) and disease relapse within 6 months after entry was significantly more common in the SITH-1 (+) group (20% vs. 0%; P = 0.0006). In patients with CD, there were no significant differences between the two groups in CRP levels and disease relapse within 6 months after entry.
[Conclusion] SITH-1 (+) patients with UC have significantly higher CRP levels, frequent disease relapse, and high disease activity. Therefore, SITH-1 may be a predictor of relapse in UC.

Authors: El-Hallag Ibrahim S , Ghanem Mohamed A , El-Mossalamy Elsayed H , Tartour Ahmed R
Published: December 2022

The electrochemical behavior of catechol was examined using convolutive cyclic voltammetry and numerical simulation at the ordinary platinum electrode and nanostructured mesoporous platinum film deposited electrochemically from the hexagonal liquid crystalline template of C16EO8 surfactant. The mesoporous platinum electrode has shown excellent electrocatalytic properties and reversibility toward the oxidation of catechol in 1.0 M HClO4. It was found the peak potential separation (ΔEp) has been lowered from 430 to 75 mV vs. SCE at ordinary and mesoporous platinum electrodes, respectively. Cyclic voltammograms of catechol on ordinary Pt electrode exhibit one anodic peak in the forward scan of potential but on the reverse scan the corresponding cathodic peak disappears and a new peak is observed at a less positive potential. But for the mesoporous platinum electrode, the voltammogram exhibits one anodic peak in the forward scan of potential and its corresponding cathodic peak in the reverse scan. On the basis of the electrochemical behavior, we propose an ECEC mechanism for the electrochemical oxidation of catechol in 1.0 M HClO4 at both electrodes. Numerical simulation was used to confirm the proposed electrode reaction.

Published: December 2022

Purpose: To identify risk factors for detection of infectious foci on 18F-fluorodeoxyglucose-positron emission tomography in combination with computed tomography(FDG PET/CT) among patients with Staphylococcus aureus bacteremia (SAB).
Methods: Cohort study of patients with SAB who underwent FDG PET/CT as part of an interventional study that was conducted at Rambam Health Care Campus, between July 1, 2015 to February 1, 2019. The primary outcome was an infectious focus detected by FDG PET/CT. Independent risk factors for detection of focal infection were identified using univariate followed by a logistic regression multivariate analysis.
Results: We included 149 patients with 151 separate episodes of SAB who underwent FDG-PET/CT. Focal infections were detected in 107 patients (70.8%). Independent risk factors for focal infection detection were community acquisition of bacteremia with odds ratio (OR) 3.03 [95% confidence interval (CI) 1.04-8.77], p-0.042 and C reactive protein (CRP) with OR 1.09 [ 95% CI 1.04-1.14], p<0.001. Primary bacteremia was inversely associated with focal infection detection with OR 0.27 [0.10-0.69], p=0.007, as were the pre-scan blood glucose levels OR 0.9 [0.98-0.99], p-0.004. The latter stayed significant in the subgroup of patients with diabetes mellitus.
Conclusion: Patients with community-acquired bacteremia or high CRP levels should be carefully investigated for focal infection. Patients who present with primary bacteremia seems to be at low risk for focal infection. Further studies should evaluate whether high glucose levels may result in false-negative infectious findings on FDG PET/CT.
Influences of Structural and Friction Parameters on Transformation of Contact State in Friction-Induced Vibration
Authors: Wang Peng , Yu Zhenliang , Deng Yongsheng , Luo Haitao , Wu Nan
Published: December 2022

To investigate the effects of friction operation conditions and vibration system parameters on the friction states transformation during vibration, the friction-induced vibration (FIV) mathematical model of a single-degree-of-freedom (SDOF) system in the direction of friction is introduced. The vibration response is solved by an iterative method combining kinematics and vibrology. The velocity and direction changes of the friction force caused by the sliding of the moving plate on top of the mass will lead to the ‘rebound’ phenomenon and the transformation of contact states. Numerical simulation and parameter studies were used to investigate the effects of stiffness constant, mass, normal force, velocity, damping ratio, and friction coefficient on the conversion of friction state, vibration response, and friction history. The numerical results show that the time of mass block and plate staying on stick status increases with normal force, static friction coefficient, the delay rate of relative sliding velocity control coefficient, and decreases with the increment of stiffness, velocity, mass, the lower limit of static friction coefficient and damping ratio. In the absence of general quantitative definitions and conclusions, the trend of this paper is to show the change of friction state during FIV through an accurate physical system.

Published: December 2022

The aim of this paper is to characterize some equations of structures for gradient almost η-Ricci Bourguignon solitons which generalize the equivalent for gradient η-Ricci-Bourguignon solitons. We prove that a gradient almost η-Ricci-Bourguignon soliton is gradient almost 1/ωu-traceless Ricci soliton with a well defined potential function f. Moreover we investigate that an Einstein manifold of constant scalar curvature is isometric to a space form with a well defined potential function f. Finally, we derived an integral formula for gradient compact case. We show that a compact nontrivial almost 1/ωu-traceless Ricci soliton with constant scalar curvature or conformal potential vector field, is isometric to a standard unit sphere, hyperbolic space and Euclidean space.
Theory of Machine Learning with Limited Data
Authors: Sapir Marina
Published: December 2022

Application of machine learning may be understood as deriving new knowledge for practical use through explaining accumulated observations, training set. Peirce used the term \textbf{abduction} for this kind of inference. Here I formalize the concept of abduction for real valued hypotheses, and show that 14 of the most popular textbook ML learners (every learner I tested), covering classification, regression and clustering, implement this concept of abduction inference. The approach is proposed as an alternative to Statistical learning theory, which requires an impractical assumption of indefinitely increasing training set for its justification.
Improved database security using cryptography with genetic operators
Authors: Devara Sandeep Reddy , Azad Chandrashekhar
Published: December 2022

Data integrity, confidentiality and authenticity, are the most valuable resources in today's digital world. As technology advances and data are being exchanged via the internet, several measures are being created to prevent unauthorised access to data. Various security models have been developed for databases, each concentrating on a different part of the database security challenge or exploring alternative conclusions about what defines a secure database. Database security refers to the measures that protect the database from intentional or unintentional risks, unauthorised users, hackers, and IP snoopers. Because the organisation requires the safety of the data in the database, a security method to protect the database is required. This paper proposes a hybrid concept known as cryptography with a genetic algorithm to provide greater security for the database. The encryption part uses a genetic algorithm along with the default authentication, which has a user id and password for the database. The database securely encrypts data in every field, stored in encrypted form. Therefore, when accessing encrypted data, the database asks for the key value to decrypt the data. So this acts as dual protection for the database, which makes the proposed technique more secure than the traditional technique. Deleting and updating the records can be done, creating new records or even database operations.

Published: December 2022

The accurate measurement of acid concentration, including hydrogen chloride (HCl) and ferrous chloride concentrations (FeCl2), is a critical part of ensuring the quality of strip steel pickling. In this study, a multi-task attention convolutional long short-term memory (MACL) neural network model was proposed to predict hydrogen ion and ferrous ion concentrations simultaneously. Firstly, in order to extract significant information from the input sequence, an attention mechanism was added to the model to calculate the correlation between the input features and the acid concentration at each time step. Next, multi-task learning explores the connections between the two tasks and exploits hidden constraints to improve prediction accuracy. Finally, deep features were extracted through convolutional long short-term memory (CLSTM) neural network, and the acid concentration was predicted. The proposed MACL model was compared with other popular prediction models. The experimental results show that proposed MACL model generally outperforms other models, indicating that proposed model has excellent predictive performance and effectiveness.

Published: December 2022

Background
Acute febrile diseases transmitted by mosquitos are a diagnostic challenge for pediatricians working Sub-Sahara-Africa. Misclassification due to the lack of rapid, reliable diagnostic tests leads to the overuse of antibiotics and antimalarials.
Methods
Between April 2016 and March 2018, 751 children presenting with acute fever and suspected of having malaria were examined at healthcare facilities located in Mwanza Region, Tanzania. Sociodemographic data and medical histories were obtained. The sensitivity and specificity of blood smear microscopy and malaria rapid diagnostic tests were compared to multiplex-RT-PCR-ELISA.
Results
One hundred thirty-seven of 698 (19.6%) pediatric patients meeting the inclusion criteria and presenting with acute fever had Plasmodium falciparum infections confirmed by PCR. 22,8% received antibiotics and 22,6% antimalarials prior to admission. No evidence of arboviral infections was found. Blood smear microscopy exhibited 33.3% sensitivity and 93.2% specificity. Malaria Rapid Test NADAL® provided 86.6% sensitivity and 98.2% specificity in detecting acute malaria infections. Only 7.2% of malaria-negative children received antimalarials at Sengerema Designated District Hospital when treatment was guided by the results of the rapid test.
Conclusions
Misclassification and premedication of non-malarial, febrile illnesses contribute to the emergence of antimalarial and antimicrobial resistance. Rapid, reliable diagnostic tests could reduce the number of antimalarial prescription significantly. This occurred when Malaria Rapid Tests were incorporated into the clinical routine and the results were translated into adequate treatment.

Published: December 2022

This review summarises medical schools’ efforts to develop social accountability (SA) determinants and indicators in the Eastern Mediterranean Region (EMR). The review used the Arksey and O’Malley framework to examine the literature on indicators and/or determinants of SA published in 1995–2021. As part of a broader project on SA, a first screening of various databases yielded 162 articles on SA in the region, and further filtering identified six articles specifically addressing the determinants/indicators of SA in two countries in the region. The Global Consensus for Social Accountability (GCSA) of Medical Schools was used to analyse the quality and content of the articles, which were assigned scores according to specific criteria of how comprehensively the medical schools addressed the 10 areas of the GCSA. The six identified publications describe the development of SA determinants and indicators in a country-specific context, but, while they make a positive contribution to measuring SA, they do not satisfactorily address some matters, including measuring impacts on local populations, the social determinants of health, primary health care approaches, policies for recruiting students, and indicating the quality of graduates in relation to community needs. This review makes recommendations on how to address these shortcomings. While SA is gaining momentum in the EMR, only a handful of countries have shared their experiences. Researchers are making efforts to turn SA guidelines into standards, but more focus and elaboration are required.

Background: Individuals with chronic ankle instability (CAI) have poor postural stability, functional limitations and low quality of life. Although nine-square exercise can improve postural control, there is limited evidence demonstrating whether it can function as an alternative CAI rehabilitation programme. This study aimed to determine the effects of nine-square exercise on postural stability and self-reported outcomes in individuals with CAI. Methods: Eighteen male collegiate athletes with CAI participated in either a 6-week nine-square exercise or a control group (n = 9 per group). At baseline and post-intervention, the participants undertook clinical tests to measures dynamic and static postural control, and self- reported outcomes regarding ankle stability and function. Results: Within-group differences, the nine-square exercise group experienced improved dynamic postural control (P = 0.004), static postural control (P = 0.001) and self-reported outcomes (P < 0.05). For the control group, only static postural control improved (P = 0.018). Post- intervention, the nine-square exercise group experienced significant improvements in dynamic postural control (P < 0.001), ankle stability (P = 0.002) and functional ability (P < 0.05) relative to the control group. Conclusion: These findings suggest that the nine-square exercise can offer an alternative rehabilitation programme for improving postural control, self-perceived ankle stability and functional ability in CAI.

This paper discusses the concepts of standard of living, modest incomes and suggests the methods of calculating their values Stakeholders involved in the production and management of social housing are identified and their roles within the sector are defined.The two economic models that can be used for the production and management of social housing are also presented and it can be seen that, while one of the models is based solely on bank loans, the other relies mainlyon public funding. For its implementation, the bank lending business model requires the existence of a strong financial market that underpins a network of successful banking institutions. While this is true in most industrialized countries, this is not the case in developing countries where this network of institutions is embryonic or non-existent. The second economic model, based on public funding alone, appears to be a reliable alternative for producing and managing social housing in developing countries. However, an economic crisis materialized by the scarcity of public financial resources could lead to a deadlock in the functioning of this model. A careful examination of the economic models for financing the production and management of social housing that have been implemented in the world, presents at least three (03) realities: First, (i) Cameroon chose the economic model basedsolely on public financing second, (ii) some countries in Europe have opted either for the economic model based on bank loans or the one based on public financing and finally, (iii) a third group of countries that have opted for a hybrid economic model based on a mixture of bank loans and partial or total use of public financing.

Background:The aim of this research was to obtain thebest concentration of liquid organic fertilizer at each dose of NPK fertilizer on the growth and yield of sweet corn. Methodology:This research was conducted at the Academic Garden, Agriculture Faculty, Tadulako University from August to November 2021.The first factor was the NPK dose consisting of 3 levels, i.e., 200 kg ha-1, 300 kg ha-1, and 400 kg ha-1. The second factor was the concentration of liquid organic fertilizer consisting of 3 levels, i.e.,without POC, 10% POC, and 20% POC. There were 9 combinations of treatments with 3 tests. The data were analyzed using the Analysis of Variance (ANOVA), then followed by the 5% level. Results : The results showed that 20% POC administration resulted in a larger cob at each dose of NPK. The administration of 400 kg ha-1NPK resulted in a larger cob at each POC concentration. Feeding of 400 kg ha-1NPK achieved better growth and yield characterized by higher plants, larger stems, longer and heavier cobs. Conclusion : The result showed that 20% liquid organic fertilizers obtained better results characterized by longer and heavier cobs.

Objectives: The objective of this study was to estimate the occurrence of Vitamin B12 deficiency in patients with type 2 diabetes mellitus treated with metformin, and the clinical and biochemical profile of vitamin B12 deficiency in them. Materials and Methods: This was a cross sectional study. Type 2 Diabetics over the age of 18 years were recruited for the study. Patients were divided into two groups - one groupof 62 patients who were on metformin for more than 6 months and the other group of 62 patients who were on other oral hypoglycemic agents or insulin. Patients were interviewed using a questionnaire. Relevant blood investigations were done. Results: The mean (+SD) age of study population was 57 (Ã‚Â±9.8) years with an age range of 35 to 79 years. There was high prevalence of vitamin B12 deficiency in patients with type 2 diabetic mellitus treated with metformin (22.6%)(p-value<0.001). This study showed a statistically significant inverse relationship between duration of metformin use and vitamin B12 levels (p-value 0.01). There was a statistically significant correlation between the dose of metformin and vitamin B12 deficiency Ã¢Â€Â“ the higher the dose, the lower the average vitamin B12 level (p-value 0.02). The study revealed significantly increased neuropathic symptoms in Type 2 Diabetic patients on metformin with B12 deficiency than with normal B12 levels (p-value<0.001). Conclusions: This study demonstrated a high prevalence of vitamin B12 deficiency in patients with type 2 diabetic patients treated with metformin (22.6%). Hencethe measurement of vitamin B12 should become an essential part of the annual review in all patients with type 2 diabetic patients on metformin therapy. The study revealed significantly increased neuropathic symptoms in Type 2 Diabetic patients on metformin with B12 deficiency than with normal B12 levels.
