Authors: Ryadi Alberto , Siregar Iskandar , Moura Carina de Melo , Gailing Oliver , Amandita Fitri Yola
Published: March 2023

Anacardiaceae is well-known for its edible fruits and economically important species in Indonesia. Approximately 3% of Indonesia's endangered and vulnerable species belong to this family. Fast and accurate species identification is crucial to support the conservation efforts for this family, such as employing DNA sequences. Species identification using DNA sequences, known as DNA barcoding, has been widely used in many applied fields. So far, the application of DNA barcoding for Anacardiaceae plant species is limited to several genera only, such as Mangifera and Spondias. This research aimed to enrich the DNA barcode references of Anacardiaceae and to evaluate the most suitable and effective genetic marker as DNA barcodes to identify species of 35 samples representing sixteen species of the Anacardiaceae family using chloroplast markers matK and rbcL as barcode regions. When comparing the morphological identification with the molecular assignments, the barcode accuracy was 62.50% (matK), 60.61% (rbcL), and 73.33% (matK+rbcL) at the genus level. All the markers failed to show a barcoding gap, even though the t-test showed that the intraspecific and interspecific genetic distances were significantly different for matK and rbcL+matK. Among others, Gluta walichii (Hook.f.) Ding Hou and Melanochyla caesia Jack were the only species successfully resolved by all markers. Nevertheless, new DNA barcodes of six Anacardiaceae species were made available by this study, enriching the genetic references of tropical flora diversity.
Strategy Complexity of Point Payoff, Mean Payoff and Total Payoff Objectives in Countable MDPs
Authors: Mayr Richard , Munday Eric
Published: March 2023

We study countably infinite Markov decision processes (MDPs) with real-valued
transition rewards. Every infinite run induces the following sequences of
payoffs: 1. Point payoff (the sequence of directly seen transition rewards), 2.
Mean payoff (the sequence of the sums of all rewards so far, divided by the
number of steps), and 3. Total payoff (the sequence of the sums of all rewards
so far). For each payoff type, the objective is to maximize the probability
that the $\liminf$ is non-negative. We establish the complete picture of the
strategy complexity of these objectives, i.e., how much memory is necessary and
sufficient for $\varepsilon$-optimal (resp. optimal) strategies. Some cases can
be won with memoryless deterministic strategies, while others require a step
counter, a reward counter, or both.
A case study on parametric verification of failure detectors
Authors: Tran Thanh-Hai , Konnov Igor , Widder Josef
Published: March 2023

Partial synchrony is a model of computation in many distributed algorithms
and modern blockchains. These algorithms are typically parameterized in the
number of participants, and their correctness requires the existence of bounds
on message delays and on the relative speed of processes after reaching Global
Stabilization Time. These characteristics make partially synchronous algorithms
parameterized in the number of processes, and parametric in time bounds, which
render automated verification of partially synchronous algorithms challenging.
In this paper, we present a case study on formal verification of both safety
and liveness of the Chandra and Toueg failure detector that is based on partial
synchrony. To this end, we first introduce and formalize the class of symmetric
point-to-point algorithms that contains the failure detector. Second, we show
that these symmetric point-to-point algorithms have a cutoff, and the cutoff
results hold in three models of computation: synchrony, asynchrony, and partial
synchrony. As a result, one can verify them by model checking small instances,
but the verification problem stays parametric in time. Next, we specify the
failure detector and the partial synchrony assumptions in three frameworks:
TLA+, IVy, and counter automata. Importantly, we tune our modeling to use the
strength of each method: (1) We are using counters to encode message buffers
with counter automata, (2) we are using first-order relations to encode message
buffers in IVy, and (3) we are using both approaches in TLA+. By running the
tools for TLA+ and counter automata, we demonstrate safety for fixed time
bounds. By running IVy, we prove safety for arbitrary time bounds. Moreover, we
show how to verify liveness of the failure detector by reducing the
verification problem to safety verification. Thus, both properties are verified
by developing inductive invariants with IVy.

Authors: Maglapuz Sharmaine Justyne Ramos , Lacatan Luisito Lolong
Published: March 2023

Quality Assurance in local higher education institutions (LHEIs) to determine its performance based on set standards is necessary as to ensure that quality education is enforced holistically. However, due to the myriad of services that the institution is providing, this task could often be overlooked. However, with the availability of Information Technology systems, and Mathematics, the regular evaluation of the LHEIs can be managed and monitored consistently. This paper discusses the development of a basic framework to allow LHEIs monitor their performance across ten (10) areas to determine quality assurance of services in an institution. This study combines the application of Data Mining Models as well as Statistical Methods to develop a Predictive Model to determine the quality assurance levels of a local higher education institution. Moreover, it provides a model in which the institution can look into in determining whether it provides quality service to its students. The developed model was tested for accuracy using existing historical data.

Authors: Mezher Mohanad , Al Abbas Amjed Razzaq
Published: March 2023

Due to their increased functionality, robotic arms provide a well-organized method for developing assistive devices. By 2035, statistics indicate that half of Germany’s population will be over the age of fifty, and every third person will be over the age of sixty. These aging societies face numerous obstacles when it comes to performing basic activities of daily living, or ""ADLs."" A growing body of research is focusing on Ambient Assisted Living, or ""AAL,"" as a novel approach to addressing the needs of elderly people. A critical objective of AAL is to improve the quality of life for the elderly and disabled and to assist them in maintaining an independent lifestyle. Robotics and technology-enabled environments will be critical in enabling elderly and physically disabled people to maintain a self-determined, independent lifestyle in their familiar surroundings. The purpose of this article is to propose the implementation of a novel intuitive and adaptive manipulation scheme by creating a human-machine communication interface between the Leap Motion controller and the 6-DOF Jaco robotic arm. An algorithm is developed to optimize the mapping between the user’s hand movement and the Jaco arm, as tracked by the Leap Motion controller. By constantly adapting to the user’s hand tremor or shake, the system should enable a more natural human-computer interaction and smooth manipulation of the robotic arm. The implementation would significantly improve people’s quality of life, particularly those with upper limb problems, by assisting them in performing several essential Activities of Daily Living ""ADLs."" The applications of this human-robot interaction will be discussed in relation to Ambient Assisted Living, with the introduction of several use case scenarios.
An Approach of Position and Torque Estimation for Induction Motor based Sensor-less Drive
Authors: Ahriche Aimad
Published: March 2023

This paper presents a new approach with stability analysis, simulation and experimental investigation of a sliding mode based estimator for rotor-position and torque-load calculation in high performance speed-sensor-less AC motor drive. The proposed algorithm is built based on the induction motor (IM) fluxes equations for two rotationg referential frames. The First equation calculates the stator flux vector while the second gives the rotor flux vector. Moreover, the stator flux equation is linked to a stator-flux rotating referential frame and the rotor flux equation is linked to a rotor-flux rotating referential frame. Among merits of the proposed technique is no necessity to rotor-speed measurement and adaptation. Thus, it is well suitable to the fully speed-sensorless scheme. The whole observer stability is verified by using of Lyapunov’s principle. Simulations are done by using Matlab-Simulink and experimental implementation is performed in order to prove the feasibility of proposed algorithm. The illustrated results are shown by using a DS1104 controller board.

Published: March 2023

The Rumei Hydropower Station is a typical cascade hydropower development project in a plateau area. The dam site is located in an area with complex topography, lithology, and geological structure. Geological disasters are developed in the area, mainly debris flow. Thus, taking the dam site and the surrounding areas as key evaluation objects, the engineering geological characteristics, geological environment characteristics, and the susceptibility and risk of geological disasters that may be caused are predicted and evaluated. The main methods used in this assessment are the binary logistic regression model and expert evaluation. The results show that the susceptibility to geological disasters is small and medium. The results of this study could provide a scientific basis for the rationality of the general layout and site selection of the project construction in the plateau water elevator level development reservoir area.
Bioinspired Trichogenic Silver Nanoparticles and Their Antifungal Activity Against Plant Pathogenic Fungi Sclerotinia sclerotiorum MTCC 8785
Authors: Guleria V. , Saxena J.
Published: March 2023

There is a pressing need for new nanomaterials for multipurpose functions. The biological synthesis of nanoparticles is environment-friendly, least toxic, and cost-effective. An experiment was designed to use extracellular amylases in the cell-free filtrate (CFF) for the biosynthesis of silver nanoparticles (AgNPs) from the Trichoderma harzianum MTCC 801 strain. Potato dextrose broth (PDB) as general-purpose growth media and amylase production media (APM) as enzyme-specific production media have been used for sub-merged fungal cultivation and nanoparticle synthesis. AgNPs synthesized in the CFF of PDB were compared with AgNPs synthesized from the CFF using APM. The cell-free filtrate obtained upon enzyme stimulation has contributed to the reduction and capping process of nanosilver. The synthesized AgNPs showed a spectral peak at 420 nm, a characteristic feature of AgNPs. The particles were monodispersed, 50 nm in size, and spherical in shape as well as have shown an antifungal effect (100% inhibition) against Sclerotinia sclerotiorum MTCC8785. This is the first report to synthesize trichogenic AgNPs using extracellular amylases against the phytopathogen Sclerotinia strain.
The Influence of Geographical Factors on Polyploidy in Angiosperms with Cartographic Evidence from the Northwestern Himalayas: A Review
Authors: Tiwana Anupreet Singh , Thummalakunta Siva Prathap , Gupta Saurabh , Singh Vijay , Kataria Ramesh Chand
Published: March 2023

The review paper comprised the impact of geographical and environmental factors on polyploidy and vice versa. The review covers different effects of geographical factors, like spatial isolation, altitude, and local climate on polyploidy, and the behavior of polyploid(s) in abiotic factors, such as temperature and light with a few examples of northwest Himalayas. The paper concludes that polyploid plants behave differently in environmental conditions, as polyploids are more prominent in higher altitudes, colder environments, and nutrient-rich soil than diploid progenitors, but have a mixed distribution in different geographical conditions. Further, polyploidy is more common among perennials than annuals, while niche differentiation depends more on the local environment. The virtual case study results from North and North Western India have been shown with the help of ArcGIS online software. The scrutiny of spatial distribution on maps highlights the fact that polyploidy is still a complex research puzzle with interesting perspectives.

Authors: Reategui M. , Reategui D. , Morales E. , Reategui R. , Aguirre C.
Published: March 2023

The objective of the research was to evaluate the effect of geographic altitude on the carbon stock in two physiographic units of the Reserved Forest of the Universidad Nacional Agraria de la Selva, Tingo Maria-Huanuco. The methodology used was the field manual for the remeasurement and establishment of plots of the Amazon Forest Inventory Network (RAINFOR), for which 2 hectares were permanently established (one hectare in low and high hills) in which the diameter (greater than or equal to 10 cm) and the height of the trees were measured. Finally, the density of the wood was obtained from previous studies. The pantropical model formula was used to estimate the carbon stock. The results show that geographic altitude significantly affects carbon stock (p < 0.05) in low and high-hill forests, concluding that this may be due to differences in meteorological variables such as precipitation, temperature, and humidity.
Evaluation of the Energy Factor and Equivalent CO2 Gas Emission by Utilization of Industrial By-products in Concrete for Environmental Protection
Authors: Saravanan B. , Divahar R. , Sangeetha S. P. , Bhuvaneshwari M.
Published: March 2023

Climate change and global warming are two of the world’s most pressing environmental issues. With CO2 being one of the most significant greenhouse gases released into the atmosphere, and cement and concrete manufacturing accounting for roughly 10% of worldwide CO2 emissions, the construction sector must employ an environmentally sustainable substance as a substitute for cement. The CO2 emissions, energy factor, and strength qualities of concrete were investigated. Those negative reaction of conventional cementitious substances is reduced by the development of binary and ternary cementitious systems. In this study, two mineral admixtures obtained from industrial waste substances, red mud (RM) and silica fume (SF), had been used as the alternatives for cement and fine aggregate was fully replaced by manufactured sand (M-sand). An experimental examination of the compressive strength, water absorption, density of concrete, equivalent CO2 emission, and energy factor for environmental benefits with the comparison of RM on SF-based eco-friendly concrete mix of M30 grade was used. A binary and ternary blended cementitious system with RM and SM was created with twelve various mix proportions, varying from 0-20% by 5% increases. From the binary blended cementitious system (BBS), based on the observed mechanical characteristic of concrete it was found that the optimum level of RM was 15% and SF was 10 % by the volume of cement. Similarly, for the ternary blended cementitious system (TBS), the level of 10% RM and 10% SF in the cement mixture provides a much higher improvement in compression strength compared to the alternative trials. The negative sign implies that replacing cement with RM and SF reduces energy consumption (-1.91% to -6.97%) and CO2 emissions (-4.52% to -16.16%). The use of mineral admixtures such as RM and SM in supplementary cementitious materials results in a significant outcome and potential impact on the production of sustainable concrete that addresses environmental issues.
Vulnerability of Mangroves to Changing Coastal Regulation Zone: A Case Study of Mandovi and Zuari Rivers of Goa
Authors: Deshpande T. V. , Kerkar P.
Published: March 2023

Goa is a coastal State located on the west coast of India, known for its pristine sandy beaches and environment. Ministry of Environment and Forest implemented Coastal Regulation Zone Notification in 1991 for monitoring the coastal zones for unplanned developmental activities but has been just for name-sake purposes (Mascarenhas 1999, Agarwal 2019). The regulation has been changed in recent years thereby making the coastal and the riverine ecosystem more vulnerable to human interference. In the name of development, various hap-hazardous, unplanned activities have taken place which is degrading the coastal and riverine environment, especially mangroves. This paper studies the vulnerability of mangroves to the changing regulations with respect to 1991 and the 2018 CRZ notifications considering the land use land cover changes in the regulated zones of Mandovi and Zuari rivers. Spatial analysis techniques and software such as Arc GIS 10.3, and ERDAS IMAGINE 2014 have been used for analysis and results. The findings from the study can be effectively implemented in monitoring the regulated zones and protecting mangroves efficiently.
Self-Healing and Thermomechanical Properties of Activated Carbon Pyrochar Derived from Municipal Mixed Plastic Waste Pyrolysis with Self-Healing Epoxy Vitrimer Composites
Authors: Rajendran Krishna Moorthy , Lamba Bhawna Yadav , Kumar Deepak
Published: March 2023

An ecological vitrimer is being developed using activated carbon pyrochar from municipal mixed plastic waste pyrolysis into an epoxy composite. Durable vitrimeric materials may be created by adding pyrochar to polymeric composites. Due to their ductility, reusability, and recyclability, vitrimeric materials have become popular and reliable materials. As a result, the self-healing temperature of composite vitrimers is lower via disulfide exchanges than that of virgin epoxy vitrimers. Additionally, compressive studies have been used to study self-healing capacities, and modulus variations have been used to highlight changes in the healing efficiency of the materials.

Published: March 2023

Mathematical Modeling of the activated sludge process (ASP) enhances the understanding of the process and improves the quality of the effluent released. However, as the process is complex and nonlinear, mathematical modeling of the process has been a challenge. In this study, multi-layer perceptron neural networks (MLP-ANN) are investigated to predict water quality parameters for better control of wastewater treatment plants employing an activated sludge process. The study area selected was in a central district of the southern state of India. The parameters to be investigated are biochemical oxygen demand (BOD), suspended solids (SS), and pH. The model is evaluated based on statistical parameters of correlation coefficient R and mean square error (MSE). The neural network toolbox of MATLAB 2015b is used for modeling and simulation study. It has been found that effluent biochemical oxygen demand was predicted with a maximum correlation coefficient of 0.927 and minimum mean square error of 0.0022, effluent suspended solids were predicted with a maximum correlation coefficient value of 0.947 and minimum mean square value of 0.0058, effluent pH was predicted with a maximum correlation coefficient value of 0.8299 and minimum mean square value of 0.0132.
Concentration of Toxic Heavy Metals and Phytochemicals in a Medicinal Plant (Asclepias fruticosa) Collected Around Mining Areas in Brits, Pretoria
Authors: Mugivhisa L. L. , Mzimba D. , Olowoyo J. O.
Published: March 2023

The use of African traditional medicine in rural and peri-urban areas is common due to its affordability and accessibility. The study aimed to determine the levels of toxic heavy metals in the medicinal plant (Asclepias fruticosa) samples collected around three mining areas in Brits using ICP-OES. The phytochemical screening analysis was done to indicate the absence or presence of different phytochemicals in the medicinal plant. The results of the qualitative phytochemical analysis indicated the presence of flavonoids, alkaloids, proteins, and carbohydrates in Asclepias fruticosa collected from all the mining areas. The results of the heavy metals showed that the mean highest concentration for all the heavy metals was recorded for Mn from the leaves of the medicinal plants. The trend in the heavy metals accumulation was roots > leaves > stems from all the sites, and the differences were significant (p < 0.05). The range of heavy metals in the plant was in the range Mn (12.33 ± 2.31-85.33 ± 51.07 μg.g-1), Zn (10.67 ± 0.58-60.33 ± 0.56 μg.g-1), Cr (3.43 ± 0.06 -34.90 ± 0.10 μg.g-1), Cu (8.67 ± 0.12-18.8 ± 1.57 μg.g-1), Ni (5.67 ± 0.12-23.23 ± 1.7 μg.g-1) and Pb (0.53 ± 0.013-1.59 ± 0.15 μg.g-1). The values of the heavy metals Cr, Zn, and Ni in the plant exceeded the recommended limits set by WHO for human consumption. Heavy metals in the medicinal plant were accumulated in the roots and not translocated to the stems and leaves. It is therefore recommended that communities staying around the mines should be discouraged from picking and using medicinal plants growing around the mines and should be educated on the safety of medicinal plants growing around the mines.

Published: March 2023

Surface water is the primary resource for raw water in drinking water treatment processes. Therefore, the presence of microorganisms, bacteria, and viruses should be the main focus in drinking water treatment, in addition to natural organic matter, which is composed of organic carbon groups derived from aquatic biota as well as organic material, organic matter from industrial and domestic waste. This study applied coagulation-flocculation followed by adsorption as the advanced treatment with activated carbon for removing organic matter and bacteria simultaneously to know each process’s performance. The results indicated that all treatment processes have a good performance for removing dissolved organic matter in water with efficient removal of 28.35%-70.75% of TOC concentration and 26.75%-55.95% of UV254 concentration. Further, the selected processes demonstrated a high percentage of removal of E. coli, about 65.35%-96.43%. However, the effect of chlorination impacted the increasing THMs concentration up to 36.32%, while the other processes could remove THMs concentration 17.25%-51.08%. Overall, this study conjectures that all treatment processes simultaneously perform well for removing dissolved organic matter, THMs, and E. coli. However, chlorination should be managed to control the formation of THMs due to the remaining organic matter in water.
How Secure is Exponent-blinded RSA–CRT with Sliding Window Exponentiation?
Authors: Ueno Rei , Homma Naofumi
Published: March 2023

This paper presents the first security evaluation of exponent-blinded RSA–CRT implementation with sliding window exponentiation against cache attacks. Our main contributions are threefold. (1) We demonstrate an improved cache attack using Flush+Reload on RSA–CRT to estimate the squaring–multiplication operational sequence. The proposed method can estimate a correct squaring–multiplication sequence from one Flush+Reload trace, while the existing Flush+Reload attacks always contain errors in the sequence estimation. This is mandatory for the subsequent steps in the proposed attack. (2) We present a new and first partial key exposure attack on exponent-blinded RSA–CRT with a random-bit leak. The proposed attack first estimates a random mask for blinding exponent using a modification of the Schindler–Wiemers continued fraction attack, and then recovers the secret key using an extension of the Heninger–Shacham branch-and-prune attack. We experimentally show that the proposed attack on RSA–CRT using a practical window size of 5 with 16-, 32-, and 64-bit masks is carried out with complexity of 225.6, 267.7, and 2161, respectively. (3) We then investigate the tradeoffs between mask bit length and implementation performance. The computational cost of exponent-blinded RSA–CRT using a sliding window with a 32- and 64-bit mask are 15% and 10% faster than that with a 128-bit mask, respectively, as we confirmed that 32- and 64-bit masks are sufficient to defeat the proposed attack. Our source code used in the experiment is publicly available.
Some New Methods to Generate Short Addition Chains

Published: March 2023

Modular exponentiation and scalar multiplication are important operations in most public-key cryptosystems, and their efficient computation is essential to cryptosystems. The shortest addition chain is one of the most important mathematical concepts to realize the optimization of computation. However, finding a shortest addition chain of length r is generally regarded as an NP-hard problem, whose time complexity is comparable to O(r!). This paper proposes some novel methods to generate short addition chains. We firstly present a Simplified Power-tree method by deeply deleting the power-tree whose time complexity is reduced to O(r2). In this paper, a Cross Window method and its variant are introduced by improving the Window method. The Cross Window method uses the cross correlation to deal with the windows and its pre-computation is optimized by a new Addition Sequence Algorithm. The theoretical analysis is conducted to show the correctness and effectiveness. Meanwhile, our experiments show that the new methods can obtain shorter addition chains compared to the existing methods. The Cross Window method with the Addition Sequence algorithm can attain 44.74% and 9.51% reduction of the addition chain length, in the best case, compared to the Binary method and the Window method respectively.
Improved Attacks on (EC)DSA with Nonce Leakage by Lattice Sieving with Predicate
Authors: Xu Luyao , Dai Zhengyi , Wu Baofeng , Lin Dongdai
Published: March 2023

Lattice reduction algorithms have been proved to be one of the most powerful and versatile tools in public key cryptanalysis. In this work, we primarily concentrate on lattice attacks against (EC)DSA with nonce leakage via some sidechannel analysis. Previous works relying on lattice reduction algorithms such as LLL and BKZ will finally lead to the “lattice barrier”: lattice algorithms become infeasible when only fewer nonce is known. Recently, Albrecht and Heninger introduced lattice algorithms augmented with a predicate and broke the lattice barrier (Eurocrypt 2021). We improve their work in several aspects.We first propose a more efficient predicate algorithm which aims to search for the target lattice vector in a large database. Then, we combine sieving with predicate algorithm with the “dimensions for free” and “progressive sieving” techniques to further improve the performance of our attacks. Furthermore, we give a theoretic analysis on how to choose the optimal Kannan embedding factor.As a result, our algorithm outperforms the state-of-the-art lattice attacks for existing records such as 3-bit nonce leakage for a 256-bit curve and 2-bit nonce leakage for a 160-bit curve in terms of running time, sample numbers and success probability. We also break the lattice records on the 384-bit curve with 3-bit nonce leakage and the 256-bit curve with 2-bit nonce leakage which are thought infeasible previously. Finally, we give the first lattice attack against ECDSA with a single-bit nonce leakage, which enables us to break a 112-bit curve with 1-bit nonce leakage in practical time.

Authors: Tuttle Denis , Griffiths Jiranan , Kaunnil Anuchart
Published: March 2023

Thailand is one of many countries experiencing changes in the demographics of its population. People are living longer and having fewer children resulting in an increasing percentage of older adults in the general population. This presents a challenge in providing care for older adults, especially in countries where there is a culture of family caregiving. This study aims to investigate the experience of family caregivers, exploring the problems of caring for older people with physical disabilities and the needs of family caregivers. This is done to better understand ways to support caregivers. Using a descriptive qualitative approach, 15 family caregivers were enrolled who provide care to older adults with physical disabilities in a rural community in Northern Thailand. The interviews were conducted face-to-face and were analyzed by thematic analysis. Findings showed two main categories from the data: problem areas and needs. The “problem area” themes are low-income households, management of activities of daily living, and access to resources. The “needs” themes are home modifications and adaptive equipment and development of a support system. The identified themes provide guidance for long term care, home adaptation, and assistive products. Future research can be done into the impact of these interventions.

Published: March 2023

Chronic hepatitis B (CHB) is a common infectious disease that represents one of the main causes of liver cirrhosis (LC) and hepatocellular carcinoma (HCC). CHB is still difficult to treat due to the lack of drugs that completely eliminate hepatitis B virus (HBV) from hepatocytes. The study was aimed to describe the CHB clinical and laboratory features, assess the efficiency of antiviral therapy and identify the factors associated with the response to antiviral therapy. The results of clinical and laboratory assessment, instrumental examination, serological and molecular testing of the patients (n = 201) followed up between 2007–2021 in the Viral Hepatitis Diagnosis and Treatment Center at the Clinical Hospital No. 85 of FMBA of Russia were assessed based on primary sources. Most of the patients in the group were males (56.7%); the HBeAg-negative patients predominated (93%). LC was diagnosed in nine patients (4.5%), among them one patient had HCC. The HBV D genotype was determined in 95.4% of cases, А genotype in 3.1% of cases, and С genotype in 1.5% of cases. After a year of treatment with the nucleos(t)ide analogues (entecavir or tenofovir) 88% of patients showed no viremia and their biochemical parameters were back to normal (88%). The overall seroconversion rate was 41.7% for HBeAg and 3% for HBsAg. Thus, high rates of virological response and enzyme activity normalization were obtained. Low baseline viremia level is an independent prognostic factor of achieving a virological response. The HBsAg level in the end of therapy makes it possible to predict relapse after the treatment cessation.

Methodology: It utilized both qualitative and quantitative data in a mixed research methodology. Also, the data was obtained from various population parameters comprising 1 sub-county director of education (SCDE), 1 quality assurance sub-county officer (QASO), 27 principals, 237 teachers, and 3730 students. The data regarding each variable was obtained from each population parameter, hence a cross-sectional descriptive study design. The independent variables comprised the frequency of in-service training and guiding and counseling programs. On the other hand, the dependent variables comprised lesson attendance and recovery, mean grades achieved, and score on teacher appraisal. To gather data about the variables, there were interviews with principals, QASO, and SCDE, questionnaires for students and teachers, and secondary data about performance in Kenya certificate of Secondary education (KCSE). The data was analyzed thematically based on the study objectives. Only means, percentages, and standard deviations were utilized to organize data. Also, the linear regression model was used on the data to find out the relation between independent and dependent variables.

Findings: It was discovered from the data analysis that in-service training impacted teacher performance, while guidance and counseling did not impact the teacher's performance. However, from the general perspective of the principal's teacher social support strategies, the data revealed little correlation with teacher performance.

Recommendations: The study recommend that there should be consistent in-service training in schools and selective guidance and counseling especially to teachers who show extreme social maladjustments. However, it is necessary that similar research be conducted especially on the influence of principal’s strategies to guiding and counseling teachers and the impacts on teacher performance.

Novel Approaches For Colon Site-Specific Drug Delivery: An Overview Of Recent Advancements
Authors: Shubham Tyagi
Published: March 2023

Nowadays, various routes of administration have been explored for the effective delivery of the drug to the target site. The oral route is considered to be the most convenient for the administration of drugs to patients. But it has a serious drawback in conditions where localized delivery of the drug in the colon is required. The colon-targeted drug delivery system (CDDS) is a potential approach for systemic and topical drug delivery in treating inflammatory bowel diseases such as ulcerative colitis, Crohn’s disease, colon cancer, and amoebiasis. CDDS would provide direct treatment at the site of the disease, reduced dose, and reduced systemic adverse effects. CDDS should be able to release the drug into the colon, indicating that neither drug release nor absorption should take place in the stomach or small intestine, nor should the bioactive agent be degraded there. Instead, the drug should only be released and absorbed when it reaches the colon. The colon is a site for both local and systemic drug delivery. This review mainly compares the primary approaches for CDDS (Colon Specific Drug Delivery) namely prodrugs, pH and time-dependent systems, and microbially triggered systems, which achieved limited success and had limitations as compared with newer CDDS namely pressure-controlled colonic delivery capsules, CODESTM, and osmotic controlled drug delivery systems. The review is also focused on the possible benefits and issues associated with the novel colon-targeted drug delivery system. Recent advancements in various approaches for designing colon-targeted drug delivery systems and their pharmaceutical applications are covered with a particular emphasis on formulation technologies.
