Using Blended Project-Based Learning to Teach Project Management to Software Engineering Students
Authors: Barbosa Marcelo Werneck
Published: January 2022

Project-based learning (PBL) approaches are common in software engineering (SE) and project management education. However, the blended learning modality is still little explored in this context. The application of PBL in blended learning environments is called blended project-based learning (BPBL). In order to fill in this research gap, this study analyzed the implementation of an undergraduate SE project management course carried out in a Brazilian private university using the BPBL method. In order to evaluate the outcomes of the adoption of this method, a questionnaire was administered to students who were also invited to identify some lessons learned, assessed using content analysis. In terms of student performance and satisfaction, the results of this survey showed that student opinions are mixed. However, the students considered more “blended-ready” are said to be very satisfied with the experience and looking forward to another one. The outcomes of this study can be used to better prepare teachers and students to adopt BPBL in software project management courses.
Machine Learning for Economic Modeling
Authors: Ghiassi Manoochehr , Simo-Kengne Beatrice D.
Published: January 2022

Accurate estimate of public expenditures is needed for budgetary planning and government decision making. Recent advances in machine learning offers the opportunity for modeling such problems. The paper introduces a novel modeling approach using a machine learning tool to forecast public expenditures and compare and contrast the effectiveness of this approach to traditional modeling alternatives. This research uses historical quarterly data from 1960-2016 to model public expenditures. Various accuracy measures (MAD, MAPE, and RSME) show that the machine learning model is the best alternative formulation and offers 97% forecasting accuracy. This model allows government decision makers to assess alternative policies with specific budgetary impacts. Furthermore, the study also shows that population aging is an important predictor of public expenditures; suggesting that demographic monitoring is indispensable for efficient fiscal planning and management in South Africa.

Published: January 2022

A mixed methods case study of the Government of Canada provides a lens through which the skills development and training and development challenges confronting the public sector in an era of digitization and smart technologies can be examined. Findings related to four key inter-related themes emerged from the analysis of survey and interview data: i) current skills sufficiencies will be challenged by coming demands; ii) digital transformation is recognized as critical, but requires significant cultural and organizational change; iii) employees are uncertain about the use of smart technologies; and iv) there is a demand for expanded training opportunities to address these challenges. These findings reflect the broader context, in particular the increasing importance of hybrid skill sets that transcend traditional boundaries between technical and non-technical functions and skills, and the need for more open and integrative venues for discussion of and training regarding digital initiatives.

Published: January 2022

Supply chain management is very critical for organizations and national economic development. Researchers and practitioners need to assess where nations are in terms of their supply chain management maturity level by identifying gaps in both practices and research. This paper aims to analyze the supply chain body of knowledge in the Indonesian context to contribute to the collection of knowledge of supply chain management in Indonesia. A structured content analysis was used to assess research papers published in English and Indonesian in peer-reviewed and accredited journals. The results proved the lack of research in the Supply chain management area within the Indonesian context. Future research guidelines were also presented as a result of this study.
Drivers of Employee Engagement in the Banking Industry
Authors: Sandhu Namrata , Sharma Sandhir
Published: January 2022

This study attempts to identify the factors that drive employee engagement in the banking industry. The empirical setting of the study was fourteen Indian banks. A survey with the help of a questionnaire was conducted to collect data (n=700). Data were analyzed using multivariate data analysis techniques. A model identifying the variables that drive employee engagement was developed and tested. Results of exploratory factor analysis revealed six factors that drive employee engagement: emotional satisfaction, perceived fairness, personal development, culture, clear communication, and compensation. Results of regression analysis showed that two of these factors, i.e. emotional satisfaction and compensation were significant in the overall model. Integration of the results with the reinforcement theory suggests that satisfaction of the emotional needs of the employees and system of compensation can be systematically, selectively and differentially used in banks to align employee behaviours with behaviours typically associated with high levels of engagement and organizational success.
Epistemic Democracy and Technopolitics
Authors: Marrone Pierpaolo
Published: January 2022

In this article I examine the structure of four deliberative models: epistemic democracy, epistocracy, dystopic algocracy, and utopian algocracy. Epistocracy and algocracy (which in its two versions is an extremization of epistocracy) represent a challenge to the alleged epistemic superiority of democracy: epistocracy for its emphasis on the role of experts; algocracy for its emphasis on technique as a cognitively and ethically superior tool. In the concluding remarks I will advance the thesis that these challenges can only be answered by emphasizing the value of citizens’ political participation, which can also represent both an increase in their cognitive abilities and a value for public ethics.

Published: January 2022

In response to the many social impacts of automated mobility, in September 2020 the European Commission published Ethics of Connected and Automated Vehicles, a report in which recommendations on road safety, privacy, fairness, explainability, and responsibility are drawn from a set of eight overarching principles. This paper presents the results of an interdisciplinary research where philosophers and engineers joined efforts to operationalize the guidelines advanced in the report. To this aim, we endorse a function-based working approach to support the implementation of values and recommendations into the design of automated vehicle technologies. Based on this, we develop methodological tools to tackle issues related to personal autonomy, explainability, and privacy as domains that most urgently require fine-grained guidance due to the associated ethical risks. Even though each tool still requires further inquiry, we believe that our work might already prove the productivity of the function-based approach and foster its adoption in the CAV scientific community.
Blood Glucose Management in Gestational Diabetes
Authors: Suganthi Kumaran S. , Sarkar Nikita S.
Published: January 2022

The prevalence of gestational diabetes mellitus (GDM) has been increasing globally and in India too, because of urbanization and the increasing occurrence of obesity. The management of GDM poses a clinical challenge, and this article focuses on its diagnosis and treatment. In India, screening of all pregnant women is recommended at the first antenatal visit and then repeat screening at 24–28 weeks of gestation if the initial screen is normal. Early intervention with counseling, glucose monitoring, diet, and exercise to achieve good glucose control could reduce both the maternal and fetal complications associated with hyperglycemia in pregnancy. The majority of cases of GDM may be managed by lifestyle modifications alone. Metformin may be prescribed as an alternative to insulin as per certain guidelines, though insulin remains the cornerstone of pharmacotherapy. Long-acting insulin detemir and short-acting insulin analogs such as insulin lispro or aspart are safe in pregnancy and help with control of blood glucose. Good glycemic control, achieved by lifestyle measures, monitoring, and medications when needed, may help achieve the goal of a successful pregnancy outcome.

Authors: Kulkarni Amruta S. , Kavitha Karakkattu V. , Sarkar Nikita S. , Purandare Vedavati B. , Bhat Savita , Tiwari Shalbha , Unnikrishnan Ambika G.
Published: January 2022

Background:

Hyperglycemia is a known risk factor for diabetic retinopathy (DR) but the association between glycemic variability and DR is unclear. We aim to evaluate the glycemic variability in DR through retrospective continuous glucose monitoring (CGM) and assess its effect on the clinical profile of participants with or without DR.

Material and Methods:

Retrospective observational hospital-based case-control study. We collected anthropometric and clinical data of 74 people with type 2 diabetes from our ophthalmology database whose retrospective CGM data were available. Among them, 37 had DR (cases) and 37 did not have DR (controls). The data were analyzed using SPSS version 27.

Results:

Duration of diabetes and glycosylated hemoglobin (HbA1c) was significantly higher and the estimated glomerular filtration rate (eGFR) was significantly lower in the cases compared to the controls. CGM markers, like time-above-range, average glucose, glucose management indicator, were higher while time-in-range was lower in the cases compared to the controls (P = ns). Time-below-range targets in people >65 years were met in a lower proportion (p < 0.05) of people in the cases (50%) compared to the controls (92%).

Conclusion:

Duration of diabetes, low eGFR, and high HbA1c showed significant association with retinopathy in type 2 diabetes. Although markers of glycemic variability did not show a statistically significant difference in cases compared to controls, all indices of glycemic variability were numerically higher in people with DR. Hypoglycemia in elderly participants with DR and its implications on achieving targets requires more research.
Using Outcomes-based Curricular Planning to Improve Clinical Education
Authors: Barber Renee , Clouser Sherry
Published: January 2022

Clerkships are an important part of veterinary education, but the many inherent challenges to teaching in a service-oriented setting result in widely variable, sometimes insufficient learning opportunities for students. There is a large body of literature devoted to improvement of clinical education, but there has been little focus on curricular planning as a means to improve clerkships. Here, we advocate for outcomes-based curricular planning of individual veterinary clerkships to maximize learning opportunities and overcome problems often reported with clinical education, such as a lack of clear learning objectives and inadequate assessments and feedback. We provide examples of the straightforward process and benefits gained when we utilized backward design and competency-based veterinary education frameworks to revise the neurology clerkship at our institution.
Maternal Depression and Preeclampsia
Authors: Lin Dong , Chen Yequn
Published: January 2022

Prenatal depression and preeclampsia (PE) are well-known risk factors of maternal and fetal mortality and morbidity. In recent years, there are emerging evidence suggesting that prenatal depression and PE could be environmental risk factors for several neurodevelopment disorders of offspring. Prenatal depression and PE were also found to be risk factors of each other. At present, the mechanism (s) of how prenatal depression and PE affect one another and their roles in the development of maternal and fetal adverse outcomes are uncertain. In this review, we outline the most recent clinical studies on the effects of prenatal depression and PE on the neurodevelopmental outcomes of offspring, as well as the plausible mechanism(s) of how these two maternal conditions affect each other and their roles in the neurodevelopment of offspring, including inflammation, oxidative stress, and maternal immune activation. We postulate that the overproduction of pro-inflammatory cytokines and increased cortisol levels in maternal depression can alter fetal neurodevelopment, and the autonomic nervous system dysfunction caused by maternal depression may accelerate heart rate and elevate blood pressure in mothers. Similarly, in PE, the elevated inflammation and exaggerated oxidative stress in the mothers, placenta, and fetus could negatively affect maternal depression on and impair the neurodevelopment of offspring. Further studies are needed to examine the combined effects of prenatal depression and PE on the health outcomes of mothers and offspring, to explore the mechanism of maternal depression in the development of PE and to investigate their roles in the neurodevelopment of offspring.

Authors: Jain Ayush Kumar , Kohli Nitish , Bansal Nitish , Sahni Girish , Aggarwal Hari Om , Mathur Manoj
Published: January 2022

Background:

Congenital clubfoot (congenital talipes equinovarus) occurs in approximately one in 1000 live births and is one of the most common congenital birth defects. The Ponseti method is at present a well-established method of treatment for idiopathic clubfoot deformities.

Aim:

The aim of the present study was to evaluate the results of serial casting in clubfoot deformity with Ponseti method on the basis of Pirani's scoring and radiological findings before and after completion of treatment.

Materials and Methods:

A total of 30 patients were enrolled in the study and were treated with Ponseti's casting after grading the severity of deformity clinically by Pirani's scoring and radiological assessment by calculating the talo-first metatarsal angle in anteroposterior (AP) view and talocalcaneal angle in AP and lateral views. The same clinical and radiological assessment was done at the end of treatment before putting a patient on foot abduction orthosis (FAO).

Results:

The average number of casts applied before full correction was 5.56 (range: 5–8). The average duration of treatment was about 6.65 weeks before the patient was put on FAO. Pirani score significantly improved from an average of 5.50 (range: 4–6) on presentation to 0.24 (range: 0–2) after correction of deformity.

Conclusion:

The Ponseti method is an excellent method for the correction of all four deformities associated with congenital idiopathic clubfoot, and we found that the addition of radiographic to clinical evaluation helps in the better assessment of correction. It provides statistically significant results both clinically as measured by Pirani severity score and radiologically assessed by talocalcaneal and talo-first metatarsal angle.

Authors: Patel Shweta , Halder Ajay , Dubey Pankhuri , Sanghamita R. , John Julie Hansa
Published: January 2022

Uterine perforation following postplacental intrauterine contraceptive device (PPIUCD) insertion is a rare event with a potential for serious injuries. In the present case, a young lady with a history of PPIUCD insertion presented with a mass having ill-defined margins and restricted mobility palpable in her right iliac region. Examination reported a conglomerated mass in right adnexa with an IUCD surrounded by a heterogeneous inflammatory collection to which omentum and bowel loops adherent to it. Additional imaging reported involvement of right iliac vessels and right ureter with upstream hydroureteronephrosis. Intraoperatively, ureter was found intact and away from the IUCD which was removed with a gentle pull, and a rent in the right posterolateral surface of uterus was repaired with delayed absorbable sutures. With PPIUCD services being provided on an unprecedented scale, it becomes prudent and ethically crucial to create a national repository to document post insertion outcomes and complications. Case report aims to inform and sensitize stakeholders about possible post insertion complications to help improve expansion of the PPIUCD programs.

Authors: Poftte Mosozuni , Rani Adhikari Uma
Published: January 2022

Non-communicable diseases (NCDs) are increasingly becoming the leading cause of morbidity and mortality worldwide. The objectives of the study were to identify the prevalence of NCDs, risk factors of NCDs and healthcare-seeking behaviour of the persons suffering from NCDs. Two hundred adults were selected by non-probability purposive sampling technique. After assessing the prevalence of NCDs through a structured questionnaire, healthcare-seeking behaviour was assessed for those adults suffering from NCDs. The tools were pre-tested and validated before data collection. The findings of the study revealed that 14.50% (95% confidence interval: 9.5–19.5) of the adults were suffering from NCDs. The most important risk factor, hypertension, was highly prevalent (56.5%). The study findings revealed a high prevalence of behavioural and clinical risk factors of NCDs. This study also revealed that only family history of NCDs was significantly associated with the occurrence of NCDs. In this study, 61.9% of the adults suffering from a NCD sought healthcare, and amongst them, 90.5% availed treatment from allopathy. Intervention programmes and creating community awareness are needed to modify risk factors.
Care of Patient with Desmoid Tumour
Authors: Nirmal Ida , Madan Latha
Published: January 2022

Desmoid tumours are uncommon mesenchymal neoplasms with a fibrotic band-like consistency. They are also called aggressive fibromatosis tumours which are locally aggressive with no potential for distant metastases. The important causes of morbidity and mortality are local recurrence and adjacent organ involvement. Desmoids can be of three types, namely intra-abdominal, in the abdominal wall, or extra-abdominal. Treatment options include observation, surgical resection, radiotherapy, conventional chemotherapy, hormonal agents and newer molecular-targeted agents. A multidisciplinary approach tailored to the individual patient is usually needed, depending on the location, local effects and the clinical course of the disease.

Published: January 2022

Background:

Older adults are likely to experience psychological and social problems due to decline in physical strength, increased health issues, inadequate financial resources, and family dynamics. In this context, they need psychosocial care services to handle such challenges. Particularly, inmates of old-age homes are more vulnerable to experience such challenges as they are away from the family care. In this background, knowing their views on psychosocial care needs while living in old-age homes is significant to improve old-age home-based care. The aim of this study is to explore the psychosocial care needs expressed by the inmates of old-age homes.

Materials and Methods:

Inmates of old-age homes were selected using purposive sampling. A total of twenty residents out of four old-age homes of Bengaluru Metropolitan City were interviewed using a semi-structured interview guide. The qualitative content analysis has been carried out to identify core psychosocial care needs out of the text data.

Results:

Three themes, namely “health-care needs,” “concerns regarding the behavior of the staff,” and “mental health needs,” are emerged.

Conclusion:

The current study findings provide insiders' views and highlight the importance of psychosocial care services to address their needs at every old-age home.
Potential Applications of Low-intensity Extracorporeal Shock-Wave Therapy in Urological Diseases via Activation of Tissue Resident Stem Cells
Authors: Wang Bohan , Reed-Maldonado Amanda B. , Ly Kim , Lin Guiting , Lue Tom F.
Published: January 2022

For many years, low-intensity extracorporeal shock-wave therapy (Li-ESWT) has been clinically applied as a noninvasive therapeutic method, for urological diseases. The major corresponding biological molecular mechanisms of Li-ESWT are to induce stem cell differentiation, neural regeneration, and angiogenesis. This narrative review aims to present an overview of the potential utility of Li-ESWT and its effects on stem cell therapies. Recent studies have also shown that the combination treatment of Li-ESWT and stem cell therapies can be a new option for the treatment of erectile dysfunction (ED), urinary incontinence, bladder dysfunction, and other diseases. The potential contributions of Li-ESWT on stem cell therapies for these diseases are studied, highlighting the influence of Li-ESWT on proliferation, viability, and differentiation capacity of certain stem cells. The potential mechanisms, including the increased expression of vascular endothelial growth factor, chemokine CXC motif ligand 5, and transforming growth factor-β1 are described herein. Li-ESWT can also activate many cellular signaling pathways. The combination of Li-ESWT and stem cell therapies is a promising strategy for urological diseases. However, a much greater understanding of the mechanisms by which Li-ESWT enhances the efficacy of stem cell therapy is still needed before this combined treatment can be recommended for large-scale clinical application.

Published: January 2022

Objective: This study aims to translate and validate the 'Smell Diskettes' screening tool from English into Arabic. The significance of this study stems from the lack of reliable and rapid olfaction screening tests available to Arabic speaking patients and healthcare practitioners. Methods: This is a prospective cohort, multi-center study. A forward-backward translation of the olfaction screening test was done to translate the text into Arabic. Data was collected from two groups: a control group (n=125) of which 84 percent were females (n=105) and a mean age of 22.4 of subjectively normosmic individuals from Alfaisal University and a patients group (n=82) of which 35.4 percent females (n = 29) with a mean age of 38.2, all of whom were diagnosed with olfactory disturbances related to rhinological pathologies, from King Abdulaziz University Hospital (KAUH) in Riyadh, Saudi Arabia. One of the limitations we faced due to convenience sampling and COVID-19 pandemic restrictions was the inability to perform a “test-retest” on study subjects. Results: The study included 207 subjects, out of whom 82 (40 percent) were patients from the rhinology clinic at King Abdulaziz University Hospital (KAUH) and 125 (60 percent) were recruited as controls from Alfaisal University. The average olfaction scores for the control group and the patients’ group were 7/8 and 5/8, respectively. Conclusion: This study has determined that the Arabic-language version is a valid and useful instrument used in clinical practice and for research purposes. The development of this tool will allow more patients in Arabic-speaking countries to be screened for olfactory disturbances.

Published: January 2022

ABSTRACT. In this study, five different thiourea derivatives were synthesized from aryl amines according to the reported method. 1-Benzoyl-3-(4-methoxyphenyl)thiourea (2) was confirmed with single crystal XRD analysis while 1-benzoyl-3-phenylthiourea (1), 1-benzoyl-3-(4-hydroxyphenyl)thiourea (3), 1-benzoyl-3-(2-nitrophenyl) thiourea (4) and 1-benzoyl-3-p-tolylthiourea (5) were elucidated with FTIR and NMR techniques. The geometry optimization of the targeted molecules was accomplished with density functional theory applying B3LYP function. The experimental (XRD) and calculated (DFT) bond angles and bond lengths were compared. The frontier molecular orbitals and molecular electrostatic potential were computed to determine the charge density distribution and possible sites for electrophilic and nucleophilic reactions of the crystalline compound. The synthesized compounds were evaluated as an anti-radical scavenger and enzyme (esterases and protease) inhibitor using in-vitro models. The results confirmed that the synthesized molecules have good anti-oxidant property while a moderate enzyme inhibiting activity. Docking study was conducted with acetylcholine and butyrylcholine esterase which suggested that molecules under study have a potential to inhibit these esterases and protease enzymes. On the basis of in-vitro studies, it is concluded that compound 2 is most active against all tested assays.

Published: January 2022

ABSTRACT. Dolomite minerals were collected from the Red Sea Mountains around the Sokhna region. The rock was collected, rinsed, and crushed using a ball mailing machine and used without further purification. The dolomite sample was characterized using FTIR, XRD, SEM/EDAX, and mapping to ensure their composition and homogeneity. The obtained data reveal that the presence of a homogenous crystalline structure of CaMg(CO3)2. The characterized rock was used as a catalyst in the eco-friendly synthesis of bis-indolyl methane derivatives by reacting two moles of unsubstituted indole and various aromatic aldehydes in the presence of Red-Sea Dolomite mineral as an economical, recyclable, easily obtained, and nontoxic catalyst under solvent-free conditions. The molecular docking study explained that the bis-indolyl methane can be considered as a small molecule stimulator of HIV-1 frameshifting and inhibitor of viral replication.

Published: January 2022

ABSTRACT. Secondary metabolites from natural products are potential sources of acetylcholinesterase inhibitors, which are key enzymes in the treatment of many neurodegenerative diseases. Inspired by the reported activities of alkaloids herein we report the chemical investigation on the chemical constituents from Beilschmiedia insignis and their acetylcholinesterase inhibitory activity. Isolation of the stem bark of B. insignis led to the isolation and identification of five aporphine alkaloids, namely isocorydine (1), norisocorydine (2), (+)-laurotetanine (3), (+)-N-methyllaurotetanine (4), and (+)-boldine (5), together with β-sitosterol (6), β-sitostenone (7), lupeol (8), and lupenone (9). The chemical structures of these compounds were obtained by analysis of their spectroscopic data, as well as the comparison with that of reported data. Acetylcholinesterase inhibitory activity revealed that all isolated alkaloids were found to inhibit AChE with percentage inhibition values ranged from 44.9 to 74.5%. This is the first report on phytochemicals from B. insignis.

Los problemas que más se evidenciaron en la investigación fue la poca utilización y manejo de las herramientas tecnológicas por la situación socio económica de los estudiantes y la falta de conectividad en los sectores de vivienda. Los resultados evidenciaron que el manejo de las herramientas tecnológicas y didácticas en el aprendizaje de los valores cívicos presentan complicaciones, debido a la poca utilización de las herramientas tecnológicas educativas de parte de los docentes y estudiantes. Se concluye que, si bien los estudiantes no cuentan con el manejo de herramientas tecnológicas, existe gran aceptación sobre el uso de herramientas educativas básicas, conllevando a mejoramiento del aprendizaje y estrategias didácticas en el alumnado. Los docentes deben enfatizar diversas alternativas didácticas con la finalidad que los estudiantes sigan aplicando los valores cívicos a través de las herramientas tecnológicas educativas, independientemente del área de estudio.

Evaluación de la Escuela Moderna en la didáctica de las ideas igualitarias. ¿Una primitiva educación feminista?
Authors: Nadal-Masegosa Antonio
Published: January 2022

El papel de la mujer en la Escuela Moderna, experiencia pedagógica de principios del siglo XX, y básica e internacionalmente conocida por el fusilamiento, en 1909, de su creador, Francisco Ferrer Guardia, es una temática interesante de investigación. Añadido a ello, y quizás aún más importante, es conocer cómo se transmitía -y si así realmente sucedía- una educación igualitaria, y cómo se enfrentaba a una arcaica sociedad de múltiples formas, a través de la coeducación de niñas y niños, y de publicaciones específicas dentro del Boletín de la Escuela Moderna, órgano de expresión del centro educativo.
Derechos de la naturaleza y personalidad jurídica de los ecosistemas: nuevo paradigma de protección medioambiental
Authors: Bachmann Fuentes Ricardo Ignacio , Navarro Caro Valentín
Published: January 2022

Actualmente, existe a nivel global un interesante grupo de normas jurídicas que reconocen u otorgan a la naturaleza o a determinados ecosistemas la condición de persona jurídica, con el fin de proteger y conservar el medio. A su vez, este otorgamiento o reconocimiento también se ha realizado por medio de jurisprudencia de los tribunales superiores. Las motivaciones pueden variar, según se conciba a ese ecosistema como un ser viviente o como un patrimonio protegible. En el presente artículo, se analizarán casos de América Latina, Norteamérica, Oceanía y Asia, para finalmente aportar algunas conclusiones sobre la base de un análisis comparativo respecto de los principales rasgos y sus posibles efectos.

Identification of Tar Mat in Zubair Formation of the X Oilfield, Southern Iraq
Authors: Abd Al-Aali Haneen M. , Soltan Basim H. , Al Mohsen Maher J. , Handhal Amna M.
Published: January 2022

The Zubair Formation was selected in the X oilfield to determine the tar zones via core, and wells logs including micro-resistivity and NMR. The study focused mainly on the main pay of the Zubair Formation, which contains a thick variable tar mat interval near the oil-water contact area, and it impacts reservoir productivity. Tar mat zones were distinguished using different paradigms such as descriptions of core and study borehole logs behavior. The result indicated that the tar mat thickness increases in the middle part of the X oil field due to the presence of high amounts of shale volume. Therefore, tar mats create barriers between oil columns and formation water, preventing the production of secondary oil in these regions.
Characteristics of Clay Soft Soil in the Mekong Delta of Vietnam and Improvement Result with Cement
Authors: Ngoc Binh Vu
Published: January 2022

The results of research on the characteristics of soft clay soils distributed in some provinces of the Mekong Delta show that most of the soils are contaminated with easily soluble salts, containing organic matter, pH < 7. Sandy clay, clay in An Giang, and clay mud in Tien Giang are less acidic, not salty, and contamination of salts in the form of sulfate- chloride. Clay mud in Hau Giang is less acidic, less salt, and contamination of salts in the form of chloride-sulfate. Clay mud in Bac Lieu and Ca Mau are lots of salty soil, contaminated with chloride of salts. Peat soil in Kien Giang is strongly acidic, not salty, contaminated with sulfate -chloride. All of them have a large compression coefficient, small load capacity, therefore they should be reinforced when construction works. Unconfined compressive strength of reinforced soils with cement showed that sandy clay in An Giang is the best, and then is soft clay in An Giang and clay mud in Tien Giang, Hau Giang, Bạc Lieu, and Ca Mau. Peat soil in Kien Giang has a low strength at different contents and days of age (with a concents 400 kg/m3 at 91 days has unconfined compressive strength qu = 201 kPa), only 12.8 to 23.0% compared to the soil elsewhere. The curing time process samples show that the compressive strength of the peat soil mixed cement is increased initially, then they were decreased over a period of 28 days.
