Procedural knowledge or conceptual knowledge? Developing the so-called proceptual knowledge in mathematics learning
Authors: Barumbun Mardyanto , Kharisma Dian
Published: November 2022

[English]: Some students might have the proper knowledge to use mathematical procedures where relevant, but do they actually have a solid understanding of “why or how” those procedures work?  Such an incomplete understanding of mathematics concepts can be a stumbling block in students’ success in mathematics. This paper aims to propose and elaborate a framework for developing proceptual knowledge combining both procedural and conceptual knowledge on differentiation that are constructed on existing mathematics learning theories on how we understand mathematics, besides my personal reflections from the independent learning on differentiation. The theoretical and practical perspectives proposed in this article share insight with anyone in developing a more meaningful mathematics-independent learning experience, especially on topics with complex mathematical formulas or procedures, such as differentiation.
[Bahasa]: Sebagian siswa mungkin memiliki pengetahuan yang tepat dalam menggunakan prosedur matematika secara relevan, namun apakah mereka sungguh memiliki pemahaman yang utuh tentang "mengapa atau bagaimana" prosedur matematika tersebut diperoleh? Pemahaman yang tidak utuh tersebut berpotensi menjadi penghalang kesuksesan siswa dalam memahami konsep matematika. Artikel ini mengusulkan kerangka kerja untuk mengembangkan proceptual knowledge (pengetahuan proseptual) pada materi turunan, yakni kombinasi pengembangan pengetahuan prosedural dan konseptual matematika yang dibangun di atas teori-teori pembelajaran matematika yang ada, serta hasil refleksi pribadi penulis dari proses belajar mandiri tentang konsep rumus diferensial. Perspektif teoritis dan praktis yang diusulkan dalam artikel ini dapat menjadi panduan bagi siapa saja untuk mengembangkan pengalaman belajar matematika yang lebih bermakna, khususnya pada topik dengan rumus dan prosedur matematis yang kompleks seperti pada turunan.

Defining the Minimum Completeness Criteria (KKM) is the first stage of implementing learning outcome assessment as part of curriculum development. Students are said to succeed in a subject if they achieve the minimum completeness criteria specified in the syllabus. This research aims to study the procedures and the method used to defining the minimum completeness criteria for Arabic lessons at Al-Fattah Elementary School, Batu, Malang. This study used the descriptive-qualitative method. Data collection methods include observation, interviews, and documentation. The results indicate that defining the minimum completeness criteria for Arabic lessons in Al-Fattah Elementary School follows two procedures. First, the Subject Teachers’ Consultation Council (MGMP) defines the minimum completeness criteria at the beginning of the school year, and for each basic competency (KD), its standard is 67, and Arabic language lesson have a standard of 71. Secondly, the minimum completeness criteria that have been defined are published for all Arabic teachers. The process of defining minimum completeness criteria in this school uses the value range method to assign the level of complexity, level of students’ absorption capacity, and efficiency level of auxiliary resources, and then calculates it using the appropriate formula to get the exact score.

Published: November 2022

The evidence of HPV vaccination effectiveness is overwhelming. The randomized clinical trials showed that all three vaccines currently in use, bivalent (CERVARIX), quadrivalent (GARDASIL) and nanvalent (GARDASIL9) effectively prevent HPV infection, cervical intraepithelial neoplasia (CIN) 1–3 and invasive cervical cancer. The results of clinical trials have been confirmed by real life evidence – population data from countries were vaccination of 12–13 girls started in 2006–08. HPV vaccination is safe. This is proven by long term follow up of the cohorts of vaccinated women. In 2020 the WHO Director-General has issued a call for action to eliminate cervical cancer as a public health problem. The document includes the interim targets for 2030: vaccination of 90% of girls by 15 years; HPV testing based screening at age 35 and 45 of 70% of women; treatment of 90% of women with screening detected cervical pathology; treatment of 90% of women with precancerous lesions and cancer of the cervix. Under elimination of cervical cancer WHO means the decrease in its incidence down to 4 cases per 100 000 population. This goal will be achieved by 2030 in countries that started HPV vaccination 15 years ago in 2006–2007.In Russia incidence of cervical cancer is on increase since 1993 from 10, 2 to 16, 1 in 2018. It is predicted that the increase will continue and in 2030 the age standardized incidence rate will reach 20 per 100 000 women. HPV vaccination and HPV test based screening will change the direction of the trend from increase to decrease and save several hundreds of lives

Nationality and ethnicity-based (cyber)bullying: how should we tackle this phenomenon in survey studies?
Authors: Pyżalski Jacek , Smith Peter
Published: December 2022

Nationality and ethnicity-based (cyber)bullying (NEBB) is generally understood as peer violence where the issues of nationality and ethnicity of the actors involved (mostly targets and perpetrators) come into play. Although central for this kind of bullying, the national, ethnic and cultural differences are not the only aspects that should be included in NEBB definition and measurement approach. Closer analysis of how specifically they may be involved and impact the dynamics and phenomenology of peer aggression suggests the need for establishing a set of criteria that may be implemented into operationalization strategies. This theoretical text presents the different level criteria that may be used for analysing and typologizing the phenomenon of NEBB. These include both behavioral and formal characteristics of hostile behaviours as well as specific issues concerning nationality and ethnicity of bullying actors and racist/nationalistic content. Then the impact of how aspects of the proposed criteria should be present in survey tools is discussed, in order to fully measure the specific types of nationality and ethnicity based bullying. Also the rationale is presented for including contextual aspects in both measurement strategies and interpretation of the results.

Authors: Oinam Termaric
Published: December 2022

Background
Mobile phones are extremely popular amongst young people, cutting across gender or locality, and can serve for improving efficiency of agricultural markets, promoting investment, and contributing to empowerment. As usage and application of ICT (Information and Communication Technologies) gadgets and gizmos are generally adhered to the youths compared to the old and aged personnel, a thorough understanding on the extent of mobile phones application in farming by tribal rural youth is a right paramount in such a challenging hill agricultural production and knowledge systems of Meghalaya.
Methods
A four stage sampling has been followed in the study. Snowball sampling was implemented to select respondents which brought total respondents to 240. All of the respondents were tribal rural youth farmers between 19–35 years. One of the indifferent criterions for the sample rural youth will be the farmer who possesses a smart mobile phone. Multinomial logistic regression (MLR) was used to predict the probabilities of the different possible outcomes of a categorically distributed dependent variable, given a set of independent variables.
Results
Parameter estimates showed that annual income, perceived ease of use, mobile phone service reliability, money spent on mobile phone monthly have no impact on the use of mobile phone application in farming whilst agricultural land holding, decision making, perceived usefulness and education have significant bearings on the extent of mobile phone application in farming.
Impaired Hip Strategy in Multiple System Atrophy (MSA) and Spinocerebellar Ataxia (SCA)
Authors: Wang Yuzhou , Liu Churong , Ma Gengmao , Lv Xiao , Ye Jinlong , Xu Yan , Li Zhong , Li Xiaodi
Published: December 2022

Background: Postural sway could be separated into several components according to frequencies. Higher frequency sway is indicative of hip strategy but how is it impaired in ataxia patients is still unknown.Methods: Static posturography examination were administered to 37 patients with spinocerebellar ataxia (SCA), 58 patients with the cerebellar type of multiple system atrophy and 53 healthy controls. Energy value trajectory during the four-step sensory organization tests were evaluated by generalized additive mixed model (GAMM). Repeated measures correlation analysis between energy value/proportions and postural performance (total postural sway, fall and tremor occurrence) were also performed.Results: GAMM analysis revealed that the middle frequency band proportion did not increase with test difficulties in MSA and SCA, indicating a failure of frequency shift. Repeated measures correlation analysis revealed that the highest correlation coefficient between energy values were found between MFV and HFV in healthy controls, illustrating components of a complete hip strategy, which was not found in SCA or MSA. In normal adults, there is a significant and positive relationship between MFP and HFP with total energy values, illustrating frequency shifts of normal stance. However, MFP was negatively related with total energy values in SCA (p>0.05) and MSA (p<0.05) patients.Conclusion: Hip strategy was not complete in SCA while it was completely disrupted in MSA, which explains why there were more falls in MSA patients. High frequency band postural sway (>2Hz) is an important component of a complete hip strategy and its origin needs further investigation.
Segments arrangement effect on improvement of self-centering PPS piers seismic performance
Authors: Anzabi P. Poorahad , Shiravand M. R.
Published: November 2022

In bridge engineering, the use of precast post-tensioned segmental (PPS) piers is increasingly expanding due to the Accelerated Bridge Construction viewpoint. Recent experimental and numerical researches have studied general seismic performance and nonlinear behavior of PPS piers without much attention to segment arrangements or joint openings. The aim of this paper is to utilize innovative segment arrangements to reduce the residual deformation, and also enhance the energy dissipation capacity of PPS piers with internal energy dissipation (ED) bars. For this purpose, nonlinear rocking dynamics of a multiple-block assembly of tied rigid rocking blocks equipped with ED bars at joints are firstly developed so that uplift moment for each joint is derived to obtain the threshold joint opening height (height above which no joint opens). Then, nonlinear static, quasi-static, and dynamic analyses are conducted on different segment arrangements of finite element models of PPS piers. It is proposed to place more segments within the threshold joint opening height by using unequal segments so that the total rotation is shared among critical joints (joints that open), and the nonlinear extent of ED bars at the bottom joint is reduced, resulting in the reduced residual deformation. It is also proposed to place a lower ratio of ED bars at the critical intermediate joints or place ED bars of a lower yield stress there so that the intermediate joints can be more effective even with small rotations. Results indicate that using the proposed segment arrangement, enhances both seismic and post-seismic performance of PPS piers.

Authors: Saka Nagavali , Krishna S. Murali
Published: December 2022

In this paper, develop Efficient Feature Extraction Based Recurrent Neural Network (EFERNN). Initially, the databases are gathered from the open-source system. After that, the pre-processing technique is developed for correcting missing values by the normalization technique of min-max normalization. The pre-processed data is utilized for feature extraction by using feature extraction techniques such as Two-Level Feature Extraction (TLFE) techniques. In level1, the ranked filter feature set technique is utilized to rank the features based on doctor recommendations. In order to execute the label-driven validation, ranking measures are used. In level 2, features are ranked and selected using a variety of metrics, including info gain, gain ratio, chi-square, and relief. In level 2, the effective features are chosen from the feature set using a fuzzy-based composite measure. In order to categorise thyroid disease from the databases, the Optimized Gated Recurrent Unit - Recurrent Neural Network (GRU-RNN) is used. In the GRU-RNN, the weight is selected with the assistance of the COOT Optimization Algorithm. The suggested method is put into practise in MATLAB, and its effectiveness is assessed by taking into account statistical measurements like kappa, accuracy, precision, recall, sensitivity, specificity and F Measure. To validate the proposed technique, it is compared with conventional techniques such as Deep Belief Neural Network (DBN). Artificial Neural Network (ANN) and Support Vector Machine (SVM).
New experimental model of chronic renal failure
Authors: Shadmanov A.K. , Okhunov A.O. , Abdurakhmanov F. M.
Published: December 2022

Background.

As is known, the modeling of chronic renal failure against the background of diabetic nephropathy is associated with the need to maximally approximate the conditions for its reproduction to the clinical one. Based on the foregoing, the priority in the reproduction of chronic renal failure should come from the modeling of diabetes mellitus, in particular diabetic nephropathy.

Purpose

To develop an experimental model of chronic renal failure against the background of diabetic nephropathy.

Methods.

Experimental studies were carried out on rabbits with the choice of the optimal method from 5 series of experiments. The evaluation was carried out according to the abortive course of the process, the development of hyperglycemic coma, the presence of angiodillation and the reproducibility of the model. For morphological studies, tissue samples in the form of pieces of kidney tissue were taken by performing an operation under ether anesthesia.

Results.

The 3 stages of nephropathy identified by us during the experiment (I - minor, II - moderate and III - severe) testified to the choice of terms for modeling chronic renal failure. The main criteria for a possible period of transition from nephropathy to the development of chronic renal failure is the presence of hyalinosis of microvessels with thickening of the membranes, which indicated the occurrence of irreversible angiogenic changes. This period is defined by us as 40 days of modeling diabetic nephropathy.

Conclusion.

In the development of chronic renal failure in a model with diabetic nephropathy, both the lack of expression of the angiogenic factor VEGF by podocytes and tubular epithelial cells and the increased expression of the antiangiogenic factor thrombospondin-1 in the renal glomeruli and interstitium play a certain role in the disruption of angiogenesis. Thrombospondin-1 inhibits the proliferation of endothelial cells stimulated by VEGF and oFRF, causing their apoptosis. As a result, the density of glomerular and peritubular capillaries decreases, glomerulosclerosis and interstitial fibrosis develop.
A Survey on Computational Intelligence Applications in Information Retrieval
Authors: Ibrahim Osman Ali Sadek
Published: December 2022

Computational Intelligence (CI) techniques have been widely employed in information retrieval (IR). CI approaches include everything from evolutionary computation and metaheuristics to machine learning techniques. These methods may be classified based on the problem domain for which they are employed in conjunction with the IR dataset representation formats. When utilizing these methods, the Vector Term Model (VTM) and Vector Feature Model (VFM) are the data representation methods that were used. The VTM represents the document and the query as vectors of term-weights. CI approaches are commonly used in VTM in conjunction with the classical Vector Space Model (VSM), while Term-weights are substituted by feature-weights in the VFM to yield feature vectors of query-document pairs. These features represent the query-document similarity matching values (such as cosine similarity and BM25), the query-document term-weights (such as TF-IDF, Okapi, and Language Models), and the document's online reputation. This paper reviews some of the research works on applying CI approaches to the VTM and VFM.

Assessment tools and strategies used by Jamaican secondary school teachers
Authors: WİLLİAMS-MCBEAN Clavia
Published: November 2022

There is an increasing understanding that assessment is an integral part of teaching and learning and that teachers are largely not adequately prepared for their assessment responsibilities. Consequently, there is a need for research on what teachers need to improve their assessment practices. To determine what Jamaican secondary school teachers need, this mixed methods study was conducted to describe the assessment tools and strategies used by secondary school teachers of various subjects and in different types of schools as the basis for future interventions. Data was collected from a survey of 1088 secondary school teachers of varying subjects and school types and further explored through interviews and observations of 32 teachers of English. Analysis of the data using descriptive statistics and ANOVA in the quantitative phase revealed that secondary school teachers primarily used traditional assessment tools and strategies, particularly tests, despite school type. Pattern coding and pattern matching in the qualitative phase confirmed these results. The findings also revealed statistically significant differences in the frequency of use of traditional and alternative assessment tools and strategies based on the subject the teachers taught. Qualitative explorations revealed that school policies that require a quota of grades and state or express positive attitudes towards tests influenced teachers despite school type to use traditional methods. The findings imply that school administrators need to implement supportive school-level policies and display positive attitudes toward alternative assessments to maximize the use of assessment to improve learning.

Published: November 2022

The present investigation is concerned with the development of non-power series solutions for the unsteady state nonlinear thermal model of a radiative-convective fin having temperature-variant thermal conductivity using Laplace transform-Galerkin weighted residual method. In the study, it is demonstrated that the symbolic solutions do not involve a large number of terms, complex mathematical analysis, high computational cost, and time as compared to the power series solutions in previous studies. The solutions allow effective predictions of the extended surface thermal performance over a large domain and time. The results of the non-power series solutions are verified numerically, and very good agreements are established. Parametric studies are carried out with the aid of the symbolic non-power solutions. It is found that as the conductive-convective and conductive-radiative increase, temperature distribution decreases since the rate of heat transfer becomes augmented and hence, the fin thermal efficiency is improved. Additionally, when the thermal conductivity of the fin increases, the temperature distribution in the passive device increases. The temperature increases with time at the different positions in the fin. Following the time histories of the solution, it is shown that unsteady state solutions converge to a steady state as time progresses. It could therefore be stated the developed non-power series analytical solutions provide a good platform for comparison of the nonlinear thermal analyses of fins in thermal systems.

Published: November 2022

Aiming at the complex electromechanical coupling effect at the joints of RP (rotating parallel) flexible robot, the electromechanical coupling dynamics and vibration response characteristics driven by AC servo motor, as well as the dynamic starting characteristics of the motor are studied. The physical model including electromagnetic and mechanical system coupling is established, and the dynamic model of the whole system is derived based on the overall electromechanical coupling effect and Lagrange Maxwell equation. With the help of Matlab/Simulink, a virtual simulation platform is built to analyze the output speed characteristics of the motor drive end and the motion of the moving base. Finally, through the joint simulation of Matlab/Simulink dynamic simulation model and Adams/controls virtual prototype model, the vibration characteristics of flexible manipulator under electromechanical coupling are obtained. The simulation results show that the electromechanical coupling effect of the motor drive end has a significant impact on the dynamic characteristics of the flexible manipulator. The conclusions obtained are of great value for improving the chiral energy of flexible machinery.

This study aims to produce a vertical dynamic load transformation model, FDV of medium weight vehicles that burden the road structure, the form of suspension work characteristics on vehicle wheels that experience disturbances and vertical loading, and the relationship between vehicle vertical dynamic loads and road structure strength, FA0  in the form of a dimensionless parameter. The experiment was carried out at the Pneumatic and Hydraulics Laboratory of the State Polytechnic of Ujung Pandang using pneumatic actuators as a substitute for vehicle weight. The dynamic load fluctuation of the medium weight category vehicle is equivalent to a pressurized air setting from 1 bar to 6 bar which puts a direct load on the suspension system on the vehicle’s wheels. The deviation, Y (cm) that occurs when there is compression on the Spring and Shock Absorber can be measured using a distance sensor, while the vertical dynamic load, FDV which burdens the road surface using a Load Cell. The data were analyzed using the vehicle dynamic load equation with pressure variable, P2 (bar), spring constant, k2 and damping fluid coefficient, c. A mathematical study of the vibration characteristics of the vehicle suspension was obtained using the Mat Lab program. The results showed that the vibration characteristics of the vehicle body experienced an overshot at a deviation of Y is 0.534 m for 0.131 seconds. The role of the shock absorber in the suspension mechanism can reduce 26.43 % of the vertical dynamic load FDV (N), and in the time interval, t is 3 seconds with acceleration deviation, is 0.25 m/s2 begins to feel comfortable. The relationship between vehicle dynamic load, FDV and road structure strength, FA0  is 0.0178. The data from the comparative analysis is then recommended as a consideration for road construction planners to determine the strength and service life of the road.

Herbal Therapy for COVID-19
Authors: Bhadoriya Upendra S. , Jain Ankit , Jain Sachin Kumar
Published: December 2022

The Covid-19 epidemic is presently ravaging the world, claiming the lives of countless people. This health crisis is well recognised to be caused by SARS-CoV-2 infection, and the problem has yet to be remedied. Many modern doctors and researchers feel that a person's disease resistance ability is critical in battling viral infections. If used appropriately, herbal therapy can be a game changer in this case, since herbal drugs significantly boost or modify immune function, enhancing resistance to microbial infections. These drugs alter the cellular immune response, enhance immunity, impart antioxidant effect, raise IgG antibody production, activate macrophages, have anti-inflammatory and analgesic properties, and so relieve symptoms and reduce viral infection pathology development. Herbal medicine can also aid in the prevention of viral infections by blocking virus entrance and replication in the host cell. Due to their vast therapeutic capabilities, Curcumin, Shunthi, Bhumiamalki, Guduchi, Yashtimadhu, Pippali, and Haritaki, among other drugs, can be examined for their efficiency and safety against viral infection. The potential uses of herbal medicine as a supplementary and alternative treatment for SARS-CoV-2 illness were reviewed in this chapter. However, further research into the effects of herbal treatment in COVID-19 is needed.

Nitric oxide (NO) donors are chemical agents that produce NO-related activity in biological systems, mimic endogenous NO-related responses, or compensate for NO deficiency. NO donors have been increasingly studied as promising therapeutic agents for insulin resistance and type 2 diabetes (T2D). Here, we provide evidence, which investigated the effects of the most frequently studied and implemented NOreleasing compounds, including sodium nitroprusside (SNP), S-nitrosothiols [RSNOs, i.e., S-nitrosoglutathione (GSNO), S-nitroso-N-acetyl-penicillamine, (SNAP)], and NDiazeniumdiolates (NONOates, i.e., spermine NONOate, diethylamine NONOate) on glucose and insulin homeostasis. Available evidence could not draw a clear conclusion regarding therapeutic applications of NO donors in T2D due to different methodological approaches (i.e., in vitro vs. in vivo) and different doses and formulations used to assess the potential effects of NO donors on carbohydrate metabolism. Considering key properties and different kinetic behaviors between various classes of NO donors, targeted compound selection, defining optimum doses, and appropriate use of NO-releasing platforms (topical vs. systemic delivery mode) seem to be critical issues that can accelerate the bench-to-beside translation of NO donors in T2D.

Household food security is an important concern for the government because it can describe food security in the smallest unit, namely household consumption. One of the government's policies regarding food security on the side of food absorption is through the Law of the Republic of Indonesia Number 18 of 2012 namely the fulfillment of diverse, nutritious, balanced, and safe food consumption patterns. The research objectives are (1) To analyze the food security of horticultural farmers' households in terms of the Energy Adequacy Rate (EAR) in Probolinggo Regency, (2) To analyze the food security of horticultural farmers' households as seen from the Desirable Dietary Pattern (DDP) in Probolinggo Regency, and (3) To analyze the factors that influence the Desirable Dietary Pattern (DDP) in Probolinggo Regency. The results showed that food security in terms of quantity and quality still did not meet the recommendations. The actual EAR of horticultural farmers in Probolinggo Regency is 1867.76 kcal/capita/day, which is still below the normative or recommended EAR of 2,100 kcal/capita/day. The actual DDP score is 74.15 which states that the actual DDP is still below the normative DDP of 100. Two parameters have a significant effect on the dependent variable, namely farm income (X1) and dummy nutrition knowledge of housewives (DX2), while dummy education head of household (X3) has no significant effect.
Inovasi Pelayanan Publik: Pengalaman dari Kota Cilegon, Indonesia
Authors: Mahpudin Mahpudin
Published: December 2022

Inovasi sektor publik menjadi penting untuk meningkatkan kualitas pelayanan sehingga berdampak pada tingginya kepuasan dan kepercayaan masyarakat terhadap lembaga pemerintah. Namun, inovasi yang tersedia justru seringkali tidak selalu efektif memberikan perubahan yang lebih baik dalam tata kelola pemerintahan. Artikel ini berupaya menganalisa hambatan apa saja yang menyebabkan sebuah inovasi sektor publik kurang bekerja optimal dengan mengambil kasus spesifik di Kota Cilegon, Indonesia. Metode kualitatif-deskriptif dipilih sebagai pendekatan penelitian. Sementara, data diperoleh melalui data primer dan sekunder. Hasil penelitian menunjukkan dua temuan utama. Pertama, inovasi pelayanan publik di Kota Cilegon tidak terlembaga secara mapan sehingga cenderung sekedar formalitas untuk memenuhi tuntutan institusi. Kedua, inovasi lebih banyak mengandalkan melalui pendekatan top-down tanpa pelibatan masyarakat yang massif, sehingga inovasi yang tercipta belum berdasarkan analisa kebutuhan publik. Hambatan yang ditemukan diantaranya: rendahnya komitmen dan political will pimpinan daerah, skema dukungan finansial tidak jelas, dan minimnya reward terhadap inovator.

BACKGROUND

Hypertension is known as one of the major causes of premature death worldwide. Therefore, controlling blood pressure becomes essential for reducing the burden of high blood pressure-related disorders.

OBJECTIVE

The study aimed to determine the impact of telemonitoring and self-care management mobile application of controlling blood pressure among patients with hypertension in Indonesia.

METHODS

This study was conducted using a queasy experiment. The intervention group received self-management and telemonitoring mobile application. They were followed by both groups for 2 months. Patients eligible for eligibility if they were 35–65 years of age, diagnosed with two or less antihypertensive drugs for hypertension, had a blood pressure of more than 140/90 mmHg. Estimated difference-in-differences (DID) for intention-to-treat (ITT) was used to measure the effect of intervention on outcome overtime.

RESULTS

A total of 64 patients with hypertension in each group joined in this study. The telemonitoring application and self-management mobile application improved outcomes relative to the control at T1 across four outcomes: 1) systolic blood pressure decreased 2.57 (95% CI (1.32 to 5.52), 2) diastolic blood pressure score saw a modest decreased 2.13 (95% CI (1.57 to 4.68). At T2, improved outcomes relative to the control were observed in systolic blood pressure (DID coefficient 2.57, 95%CI (1.32 to 5.52), diastolic blood pressure (DID coefficient 3.57, 95%CI (1.89 to 6.60).

CONCLUSIONS

The telemonitoring and self-care management mobile application has promising results on controlling blood pressure among patients with hypertension in Indonesia. Healthcare policy may need to integrated application of telemonitoring on self-management intervention and facilitate for future development to help patient’s hypertension could manager their disease and reduce mortality.
