Overcoming the ‘Fatigue’ in Retirement
Authors: Adinkrah Bernard Kofi
Published: May 2022

There comes a time when every worker in the formal sector goes on retirement and there is a need to effectively plan towards that period. Today, many retirees across the Africa live in poverty. This occurs because the average worker does not prepare adequately for retirement. This transcends to Ghana where most people work in the informal sector. Hence, there is a need to develop strategies that would help people live comfortably in their old age when they can no longer work. Retirement is a crucial stage in life that should not be taken for granted. One basically stops working for a paid income and survives on their own savings or investment proceeds. Retirement is probably the most critical period for finishing unfinished goals. These goals, whatever they may be, have crucial financial implications. Unfortunately, what is not available during retirement is a salary and that is where pensions and retirement planning come in handy. Planning for retirement prior to its occurrence will help retirees live comfortably. The purpose of writing this book is to take the ‘tire’ out of retirement. It seeks to provide a simple and yet comprehensive basic guidance for the benefit of both public and private workers on retirement planning. It is envisaged that it will serve as a handbook to be used at workshops for both public and private workers in the Ghanaian society. The book has been prepared with sufficient reference to the Ghanaian and the Western context to meet the needs of both Ghanaians and workers outside Ghana. It may also be used as an academic material, to be specific, as a textbook. Also, advanced students pursuing specialized programmes in guidance and counselling at M.Ed./M/A/MPhil/Ph.D. levels will find this book as a useful introductory material to undertake more detailed work.

Authors: Goldin Deana , Cabán-Alemán Carissa , von Harscher Heidi
Published: May 2022

Moral injury develops from enduring complex moral conflicts that occur when one's beliefs and values are violated by committing, perpetrating, failing to prevent, or witnessing acts that transgress one's deep moral compass. In response to the coronavirus disease 2019 pandemic and the extraordinary impact to patients and health care systems around the globe, telemental health has rapidly expanded as a means to optimize resource use and comply with social distancing mandates. Social determinants of health, which include financial inequity, have influences on pandemic situations, such as physical distancing and lockdowns, resulting in disproportionate delays in timely mental health diagnosis and management. The current article discusses an overview of how the demands of the pandemic have forced mental health clinicians working in telemental health to face a wide range of complex ethical and moral dilemmas.

Published: May 2022

Angiogenesis, a multistep process regulated by positive and negative soluble factors, plays an important role for tumour progression (growth, invasiveness and metastasis).A mutual stimulation occurs between tumour cells and neoplastic cells by paracrine mechanism. Host inflammatory cells can also secrete angiogenic factor. Several experimental researches suggest that Increase of mast-cells density (MCD) Is joined wlt:h Increase of microvessel density (MVD). To evaluate the putative role of MCD in the angiogenic process we studied, for the first time, a series of 16 poorly differentiated grade 3 (G3) dog mastocytomas. Mast cell tumours (MCT) are common in dog with an incidence much higher than those found In human, consequently dog MCT can be a valid model to study angiogenic process. Serial sections for each MCT were processed both wlt:h toluidine bleu specific for MC identification and immunohistochemical method using the polyclonal antibody anti FVIII - RA as an endothelial marker. Slides were evaluated using an image analysis system (Quantimet 500 LeicaJ. The three most vascular areas ••hot spots•• in each tumour tissue were selected and Individual vessels and Individual mast cells were counted at 400.x. Both MVD and MCD means and standard deviation (s.d.) were determined both for each tumour and in the global series. MVD and MCD means value were 18 ± I I and I 06 ± 97 respectively. The regression analysis (pearson-s test) between MVD and MCD failed to show any correlation (p= n.s.). On these basis we speculate that cutaneous malignant mastocytomas are low vascularized tumour and neoplastic mast cells should not playa major role in the angiogenic process.

The revolution of wireless communications regulations in Nigeria signifies enhancement in ICT innovation, investment opportunities, fair competition and inclusive growth through, strategic collaboration and partnerships to protect and empower consumers. The demand for data in the 4G (Fourth Generation networks) and 5G (Fifth Generation networks) is becoming excessively high and the solution is being investigated to effectively utilize the available spectrum at the physical layer across different protocols to speed-up bandwidth access from 2.5 to 10 times to support new high-performance applications (e.g. e-health, high definition video streaming, network gaming, e-commerce, e-government etc.) To realize the above targets the operators need to provide some form of Quality of Service (QoS) and Quality of Experience (QoE) assurance. The 8-Point Agenda of the EVC/CEO of Nigerian Communications Commission (NCC) factored upon a tripod of Availability, Accessibility and Affordability of Service, the Nigerian Communications Act 2003, the National Telecommunications Policy, the Strategic Management Plan of the Commission, the National Digital Economy Policy and Strategy and other extant regulatory provisions are utilized to regulate telecommunications services and promote universal access in Nigeria. This paper reviewed the QoS Key Performance Indicators (KPIs) like The CSSR, DCR, SDCONG, and TCHCONG CSSR, MTTR, and Power Availability for 2G, 3G and 4G according to the International Telecommunications Union Standards (ITU-T) and NCC criteria. Literature review on QoS and congestion control analysis were conducted and the research gaps were identified for the development of effective regulations and operational excellence. Recommendations were made on the way forward to explore the optimization of electricity supply to base station using hybrid system, renewable and green energy to reduce operational cost and emissions.

Authors: Chuku G.O. , Akonye L.A. , Eremrena P.O.
Published: May 2022

The Response of African Yam Bean to charcoal and calcium chloride treatment in a crude oil polluted soil was carried out. 10kg of soil was polluted with 600ml of crude oil and was remediated with 500g of charcoal; the germinated seeds were pre-treated with 25g/l of Calcium chloride for 15mins before it was sown. The different treatments were: Control, 6% pollution, 6% pollution and charcoal, Charcoal only, Pre-treatment with calcium chloride, Pre-treatment with calcium chloride and 6% pollution, Pre-treatment with calcium chloride and 6% pollution and charcoal, Pre-treatment with calcium chloride and charcoal. Results showed that crude oil pollution impacted negatively on the parameters studied, the addition of materials (Charcoal and Calcium chloride) to the crude oil polluted soil improved the growth of African yam bean. Calcium chloride pre- treatment inhibited the emergence of AYB in a polluted soil. There was a significant difference (P>0.05) in the plant height, leave area, number of leaves, carbohydrate content, stem girth and root length, while treatments had no significant difference in the chlorophyll content and number of roots. The combined treatment (CaCl2 + Charcoal + pollution) did not show any significant impact on the growth and biochemical parameters when compared to the single treatments therefore; Charcoal and Calcium chloride are very good biostimulants but are more effective when they are applied separately.

Published: May 2022

Device simulation was employed to investigate the effect of metal back contact electrodes on the performance of n-type CdS/p-CIGS thin film solar cells using varying thicknesses of absorber layer at operating temperature of 300K. The effect of working temperatures was also studied from 300K to 400K in steps of 10K. The simulations were carried out using standard solar cell capacitance simulator (SCAPS) 3.3.03 version software. The results showed better efficiencies at the optimized thickness of 3µm for all the back contact electrodes under study. The maximum efficiencies of 17.5 %, 15.5 %, 11.5 %, 3.5 % and 3 % were estimated for CIGS thin film solar cell at 300 K for platinum, gold, cobalt, silver and copper back contact electrodes respectively. The efficiency decreases as the operating temperatures increases from 300 K to 400 K. It is recommended that the optimized thickness of 3 µm is appropriate as absorber layer for efficient and cost effective CIGS thin film solar cells for economic reasons.
Human Health Risk Assessment of Heavy Metal Contamination in an Artisanal Gold Mining Community of Kogi State, Nigeria
Authors: Abutu O.M. , Shuneba I.L. , Shu E.N.
Published: May 2022

Artisanal and small-scale gold mining (ASGM) is known to improve the standard of living in the host communities and economic performance of countries involved. However, despite the positive impact on the economy, ASGM is a significant point source of uncontrolled mobilization of hazardous chemicals, notably heavy metals into the environmental media such as soil, air and water. This study assessed human health risk of exposure to heavy metals in soil around artisanal gold mining in Ike community of Kogi State. Twelve (12) soil samples obtained from the gold mining area were analysed for heavy metals (As, Cd, Ni, Pb and Zn) using Atomic Absorption Spectrometry (AAS). Measured concentrations of these metals were used to calculate health risk of children and adults using health risk assessment models. The results showed that mean values of heavy metal concentrations in the soil reflected low metal load (<1) with decreasing order of As>Pb>Zn>Ni>Cd. The results obtained from analysis of non-carcinogenic risk demonstrated that hazard index values of various heavy metals for three exposure pathways (ingestion, dermal and inhalational) were < 1 for children and adults populations. However, As recorded hazard index values > 1 for ingestion pathway for both populations. It was found that As recorded carcinogenic risk of 1.85E-03 for children and 9.86E-04 for adults and Cd recorded 4.67E-04 for children. These values exceeded the safety limit, ranging from 1E-06 to 1E-04, as stated by US Environmental Protection Agency. The study showed that As might pose carcinogenic and non-carcinogenic risks for both populations. Also, Cd might pose carcinogenic risk for children. Hence, As and Cd would be regarded as elements of serious concern in the study area.
Protective effect of dexmedetomidine pre treatment against myocardial ischemia reperfusion injury in rats
Authors: Sha Qin , Jiang Hui
Published: May 2022

Purpose: To determine the protective effect of dexmedetomidine pre-treatment against myocardial ischemia-reperfusion injury (MRI), and the involvement of ER stress and protein kinase R-like ER enzyme (PERK) signaling pathway in the process.

Methods: Sixty male Sprague-Dawley (SD) rats were assigned to three groups: sham, model (ischemia-reperfusion), and dexmedetomidine pre-treatment groups. Myocardial infarction area was measured using 2,3,5-triphenyl tetrazolium chloride (TTC) method. Changes in heart structure were examined using H & E, while myocardial cell apoptosis was determined with TUNEL assay. The protein expression levels of CHOP, glucose regulatory protein 78, ATF4, eukaryotic translation initiation factor 2-α (elf2-α), and PERK were assayed with Western blotting.

Results: RPP, myocardial infarction area, myocardial cell apoptosis rate, and the expression levels of CHOP, GRP78, ATF4, elf2-α, and PERK were significantly raised, relative to sham. The structure of myocardial cells in sham-operated rats was intact and orderly. In contrast, the arrangement of myocardial cells in the model group was disordered, and the myofibrils were broken or wavy. However, the arrangement of myocardial cells in the dexmedetomidine group was significantly improved, when compared with the model group.

Conclusion: Pretreatment with dexmedetomidine may exert a protective effect against MRI through suppression of ER stress and PERK signaling pathway. Further preclinical studies would be required to validate these findings.

Let $P$ be a set of $n\geq 3$ points in general position in the plane. The
edge disjointness graph $D(P)$ of $P$ is the graph whose vertices are all the
closed straight line segments with endpoints in $P$, two of which are adjacent
in $D(P)$ if and only if they are disjoint. We show that the connectivity of
$D(P)$ is at least
$\binom{\lfloor\frac{n-2}{2}\rfloor}{2}+\binom{\lceil\frac{n-2}{2}\rceil}{2}$,
and that this bound is tight for each $n\geq 3$.

Hydrocarbon production forecasting for the field lifetime in the short and long term is an important phase, the accuracy of this process plays a tremendous role in giving the decision of reasonable field management and development. In this article, the logistic growth models using the function MATLAB’s ‘nlinfit’ have been built to forecast oil production yield for the Oligocene C sequence, X field, Cuu Long basin. Thanks to the combination with the history matching process, the logistic growth model expressed high accuracy, the results of the model are very close to the actual production data with a relative error of 1,85%. The article analyzed and evaluated the production parameters of wells obtained when building logistic growth models such as the time at which half of the carrying capacity has been produced, the steepness of the decline of the rate, and the production rate of the wells at the forecast time. Without applying any improved oil recovery method, the decline of the rate of all wells approaches 100 bbl/d before reaching the validity period of the oil and gas contract. This is the basis for operators to establish and improve field development plans.

Published: May 2022

The aim of this study is to encourage the use of Rhododendron luteum Sweet, distributed in high altitudes in its natural habitat, in planting designs and landscape architecture and to cultivate these plants by seed propagation. In this context, the effects of different altitudes on R. luteum germination and post-germination seedling growth were investigated. The germination success of R. luteum seeds collected at 3 different altitudes, 1,586 m, 1,760 m and 2,100 m a.s.l., was investigated under greenhouse conditions at a temperature of 25 ± 2 °C and humidity of 70 ± 2% and in soil, peat, soil + peat (5:5), peat + sand (7:3), soil + sand (7:3) and soil + peat + sand (4:4:2) propagation media. The post-germination seedling height, root length, and the number of leaves of the seedlings were determined. Different altitudes had significant effects (P < 0.05) on height, root length, and the number of leaves of the seedlings. The highest germination percentage was 76.69% with the seeds collected from 2,100 m. Furthermore, seedlings that grew from these seeds possessed the best seedling growth with a greater height, longer roots, and a greater number of leaves. Keywords: landscape architecture, Rhododendron luteum, seed propagation, variation

Residual Stresses Induced while Machining Inconel-718 in Cryogenic Environment: Numerical Estimation
Authors: Kumar Gupta Suraj , Kumar Sharma Dinesh
Published: May 2022

Nickel alloys are recognized to offer great strength, good corrosion resistance, and outstanding thermal stability when compared to typical materials, these features can be utilized in aerospace and turbine sectors. Nickel alloy is one of the most difficult to cut materials since it is having a high strain hardening propensity and low thermal conductivity. But due to the outstanding qualities of Inconel-718, these types of material cannot be ruled out, and hence they are being machined in a cryogenic environment. Many studies have been conducted in recent years to quantify and predict machining-induced residual stress. It has been concluded that the residual stress can be viewed as a function of machining parameters. However, during the cutting process, the combined effect of thermal and mechanical loads has a direct impact on the stress field. Despite conducting experimental studies, there is a significant requirement to build numerical models to simulate residual stress distribution on machined surfaces in order to identify appropriate machining settings. The effect of cryogenic cooling on residual stress has yet to be modeled. In a cryogenic environment, finite element modeling has been successfully used to forecast residual stresses caused by machining. Tungsten Carbide was used as a single-point cutting tool for 2D orthogonal cutting in a cryogenic environment using Abaqus CAE/6.14. In this research work, it has been observed that the geometrical characteristics of the tool and the cutting parameters affect the residual stress. The results provide the correlation between residual stress and the above parameters.

St. Petersburg is a large, populous city. It needs a well-developed transport infrastructure. One of the main advantages of the tram is its uninterrupted operation in almost all-weather conditions.

Currently, the park of public transport in St. Petersburg is being updated, priority is given to environmentally friendly transport, the use of electric transport, gas motor fuel.

The question of the implementation of projects that would improve the ecological situation in the city is relevant. The tram has the largest carrying and throughput capacity among urban land transport and a signifi cant service life. It is an environmentally friendly type of ground urban passenger transport while ensuring a high level of passenger safety. The development of tram traffi c is analyzed.

The advantages of using this type of ground urban passenger transport are considered. The tram market in Russia has been studied and two options for updating the rolling stock have been proposed.

In order to study public opinion, a survey of more than a hundred students of the Emperor Alexander I St. Petersburg State Transport University was carried out.

A survey was conducted among residents of diff erent districts of the city, it was proposed to change some routes and add new routes within the existing tram lines.

The necessity of updating the rolling stock, contact network and traction substations is substantiated; isolation of tram lines; railroad upgrades; reforming the route network; creation of convenient infrastructure at bus stops. Options for implementing the development of tram traffi c are proposed.

Authors:   Department of Computer Science, AIUB, Morol Md. Kishor
Published: May 2022

Cloud computing is the on-demand usage of computer resources through the internet, allowing us to relocate application software and databases. Its purpose is to deliver IT services that enable clients to benefit from the pay-per-use model's substantial cost advantages and the ability to flexibly scale up or down without having to make significant investments in new hardware. On the other hand, the provider manages the data and services under this cloud architecture. Consequently, cloud clients have less control over their outsourced data and depend on cloud service providers to safeguard their data and infrastructure from both external and internal threats. In this study, we look at information security in cloud computing. It is the consideration of information on the cloud, considering security concerns. This article will go through data protection strategies utilized all around the globe to provide optimum data security by lowering risks and threats. Information accessibility is beneficial for various cloud applications, but it poses risks by exposing data to apps that already have security escape clauses. In addition, the presentation will outline information security highlights for Data in Transit and Data at Rest.

A 2022-es év rendkívüli bizonytalanságok között kezdődött el az európai gazdasági térben. Az év eleji kilátások értelmezését megnehezítette, hogy a 2020-as koronavírus- járvány miatt hirtelen leállt, majd újra beinduló konjunktúra nyomán jelentősen megváltozott a keresleti és kínálati szerkezet. A 2021-es esztendő gazdasági visszapattanást hozott, de folytatódását a nemzetközi termelési láncok zavarai világszerte lefékezték, eközben megdrágultak kritikus termékek és szolgáltatások. A gyors árnövekedés előrevetítette a meghatározó jegybankok monetáris pozíciójának módosulását, ezen keresztül az árak, kamatok, árfolyamok – térségenként eltérő ütemű – megváltozását. A fenyegető előjelek ellenére meglepetést okozott, hogy februárban kitört a háború, amely hátrányosan hat a globális növekedési kilátásokra, a leginkább érintett európai gazdaságok számára pedig új helyzetet teremtett. A magyar gazdasági folyamatokat a nemzetközi bizonytalansági tényezőkön túl a hazai politikai ciklus fejleményei és jövedelmi, költségvetési, inflációs következményei is nagyban befolyásolták. A koronavírus-járvány továbbra is kockázati tényező, noha a megelőző két évhez képest a gazdasági pálya jellegét kevésbé határozza meg, társadalmi-gazdasági utóhatásai mégis lényegesek. Legfőképpen azonban a biztonságpolitikai vonatkozások befolyásolják az európai és közelebbről a magyar gazdasági pályát. Bár 2021 végére az Európai Unió gazdaságainak többsége, így Magyarországé is elérte a pandémia kitörése előtti szintet, a kilábalási folyamatot megtörte a háború. Az infláció már azt megelőzően is tartósan emelkedett, a háború nyomán a nyersanyag- és élelmiszerárak még inkább megugrottak, a nemzetközi ellátási láncok működési zavarai fokozódtak. Az új világgazdasági helyzet Magyarországon kiigazítást indokol, arra a belső tényezők miatti egyensúlyromlás is kellő okot ad. A számított alapváltozat szerint a szükséges kiigazítást feltételezve, tovább nem romló külső viszonyok között a magyar gazdaság továbbra is növekszik 2022-ben, de a korábbi ütem megfeleződik. A GDP bővülése 9 százalékot meghaladó infláció, mérsékelt beruházási tevékenység, enyhén romló külső egyensúlyi mutatók mellett következik be. A háború elhúzódása, az uniós forráshoz való hozzáférés megnehezülése, illetve a kiigazítási folyamat zavarai esetén azonban az alapváltozatnál jóval előnytelenebb gazdasági pályák is kialakulhatnak.

Designing 10T SRAM for noise and Leakage Power Reduction using Stack Transistor Technique – A Review
Authors: Miss. Seema S. Naik  , Dr. P. B. Patil
Published: May 2022

The SRAM Semiconductor memory, utilize a bistable latch circuit to store logic 1 or 0 data. It differs from dynamic RAM (DRAM) which requires a periodic refresh operation to store logical data. SRAM power consumption varies with operating frequency, i.e., at higher frequencies, it consumes very high power, similar to DRAM. Because the cache included in the microprocessor required high-speed memory, SRAM can be used in the microprocessor for this purpose. DRAM is often used in processor main memory, where density is more important than speed. SRAM as well used in industrial, scientific electronics, and automotive subsystems. In this paper, the SRAM investigation report was studied to develop a new SRAM design for low power consumption.

Introduction

The objective of the present study was to characterize > 65-year-old patients with breast cancer according to clinicopathological, molecular and laboratory factors.

Material and methods

A total of 723 breast cancer patients, who had been diagnosed and treated during 2005–2019, were retrospectively reviewed. Patients > 65 years of age (92 patients) were compared with < 50-year-old women (306 patients). We analyzed 398 women from 723 patients.

Results

Overall survival analysis was conducted for both groups, separately and combined. Patients with BC aged > 65 years were characterized by G1-2, higher lymphocyte values, lower platelet (PLT) counts and lower NLR or PLR values than patients <50 years of age.

Conclusions

Age > 65 years is a negative prognostic factor independent of other factors.
School Problems among Left-Behind Children of Labor Migrant Parents: a study in Vietnam
Authors: Nguyen Luot , Nguyen Nhung , Truong Ha , Giang Mai
Published: May 2022

Background

Many studies have shown the effects of parental migration on the psychological and daily life of left-behind children (LBC) of labor migrant parents, but the results on school-related problems of LBC remain inconsistent. Additionally, there is a dearth of research on the factors affecting school problems among LBC, especially in the socio-cultural context of Vietnam. The purpose of this study was to confirm the school problems encountered by LBC in comparison with non-left-behind children (non-LBC). The study also aimed to examine variables of bonding of caregivers with children and resilience of children affecting school problems of LBC.

Participants and procedure

The convenient sampling approach was used in the study. The study sample included 792 Vietnamese school students (M¬age = 12.65, SD = 1.60), with 439 children of labor migrant parents and a control group of 353 children of non-migrant parents. The School Problem Questionnaire, Parental Bonding Instrument and the Resilience Scale were employed in this study.

Results

There was no difference in school problems between the LBC and non-LBC groups. Resilience by goal planning (RGP), resilience by affect control (RAC), and resilience by family support (RFS) are identified as protective variables for children to overcome difficulties encountered in schools, with regression coefficients of -.21, -.33 and -.20, respectively. Meanwhile, bonding of caregivers with children by control (BCCo), resilience by positive thinking (RPT) are considered as factors that increase school problems among LBC with the same regression coefficient of .12.

Conclusions

Activities to support LBC should pay attention to improving resilience, namely affect control, goal planning, and promoting the role of caregivers for LBC.

Introduction and Aim: Clinacanthus nutans (C. nutans) possesses antimicrobial, anticancer, and anti-inflammatory activities. The present study aimed to carry out phytochemical analyses of aqueous and ethanolic extracts of C. nutans leaves and also its cytotoxic potential on human gingival fibroblast cell line HGF-1.
 
Materials and Methods: Phytochemical analyses was conducted using Gas Chromatography Mass Spectrometry (GCMS). Cytotoxicity testing was carried out by treating the HGF-1 with different concentrations (50,100, 200, 400, 800, 1600, 3200, 6400 µg/ml) of both the aqueous and ethanolic extracts of C. nutans leaves using MTT assay. The control comprised only the cell suspension and culture medium.
 
Results: Phytochemical study revealed 53 compounds. Furfural, 2-furanmethanol, butyrolactone, phenol, benzeneacetaldehyde, 4H-Pyran-4-one,2,3-dihydro-3,5-dihydroxy-6-methyl-, vitamin E, campesterol, stigmasterol,.gamma.-Sitosterol and lupeol were the compounds identified in both extracts. Both the extracts did not exhibit any cytotoxicity on HGF-1 based on MTT assay with IC50 values of 1099 µg/ml (ethanol extract) and 2627 µg/ml (aqueous extract).
 
Conclusion: This study showed that ethanol and aqueous extracts of C. nutans leaves contained varied phytochemical compounds and were non-cytotoxic on human gingival fibroblast cell line under the present test conditions.
Influence of duration of menopause on bone turnover markers in post-menopausal women
Authors: Rai Tirthal , Rai Mayur , DSa Janice , Rai Srinidhi , Hegde Rishabh
Published: May 2022

Introduction and Aim: Osteoporosis is common among women following 10 years of cessation of menstruation, due to bone loss accelerated by menopause. The study was done to evaluate the effect of duration of menopause on bone turnover markers (BTMs).
 
Materials and Methods: The study involved 100 postmenopausal women; 50 osteoporotic and 50 non-osteoporotic. Comparison and correlation of serum calcium, phosphorus, alkaline phosphatase (ALP), serum osteocalcin (sOC) and urinary hydroxyproline (uHP) were done based on duration of menopause. Comparison of biochemical parameters was done using Independent t-test and ANOVA test for two groups and more than two groups respectively. Correlation was done using Pearson’s correlation test. Statistical significance was considered at p<0.05.
 
Results: The sOC significantly declined and uHP levels increased between quartiles of duration of menopause among study participants. (p<0.001). However, in those without fractures, sOC and uHP were higher in those with <7 years since menopause (YSM) and then plateaued after 8 YSM. The percentage of osteoporotic women having >15 YSM was 82%. Duration of menopause correlated better with sOC (r=-0.633) than uHP (r=0.575) (p<0.001).
 
Conclusion: Osteoporotic fractures were higher in more than 15 YSM. There was no difference in both sOC and uHP in those with fractures, proving non-significance of screening these markers once the fractures have occurred. As sOC correlates better with duration of menopause, monitoring of sOC in early years of menopause is required to prevent osteoporotic fractures and associated burden through prophylactic treatment.
Folklore claims of medicinal plants against sprain from the Western Ghats region of Dakshina Kannada district, Karnataka state, India
Authors: A. Yogeesha , G. Krishnakumar
Published: May 2022

Introduction and Aim: Plants form the primary source of medicinesboth in traditional and modern methods of treatment. People residing at remote and rural regions still depend on traditional herbal medicine for their primary health care needs. This study aimed to document ethnomedicinal plants used in the treatment of sprain in the Western Ghats region of Dakshina Kannada district, Karnataka state, India.
 
Materials and Methods: An ethnobotanical study was carried out in Western Ghatsregion of Dakshina Kannada district, Karnataka during 2018-2021 to document the medicinal plants used by traditional practitioners to treat sprain. Data was collected using a semi structured questionnaire and open-ended interviews with herbal healers. Data was analyzed using simple statistical methods and few quantitative parameters.
 
Results: A total of 40 plant species of belonging to 30 families have been documented. Some significant recorded plant species are Aloe vera, Litsea glutinosa, Cissus quadrangularis, Abrus pulchellus, Antidesma acidum, Holarrhena pubescens, Litsea wightiana and Ziziphus rugosa. Younger generations are ignoring the uses and cultural importance given to such ethno- medicinal practices. This knowledge is based on oral tradition often passed on to the next generation.
 
Conclusion: Practitioners of this region do not have any written documents pertaining to their precious knowledge. Hence there is an urgent requirement to document and preserve the traditional knowledge inherited by tribes and ethnic communities before it is completely lost.
