Dynamical Analysis of a Fractional Order HIV/AIDS Model
Authors: Perdana Putra Septiangga Van Nyek , Suryanto Agus , Shofianah Nur
Published: April 2021

This article discusses a dynamical analysis of the fractional-order model of HIV/AIDS. Biologically, the rate of subpopulation growth also depends on all previous conditions/memory effects. The dependency of the growth of subpopulations on the past conditions is considered by applying fractional derivatives. The model is assumed to consist of susceptible, HIV infected, HIV infected with treatment, resistance, and AIDS. The fractional-order model of HIV/AIDS with Caputo fractional-order derivative operators is constructed and then, the dynamical analysis is performed to determine the equilibrium points, local stability and global stability of the equilibrium points. The dynamical analysis results show that the model has two equilibrium points, namely the disease-free equilibrium point and endemic equilibrium point. The disease-free equilibrium point always exists and is globally asymptotically stable when the basic reproduction number is less than one. The endemic equilibrium point exists if the basic reproduction number is more than one and is globally asymptotically stable unconditionally. To illustrate the dynamical analysis, we perform some numerical simulation using the Predictor-Corrector method. Numerical simulation results support the analytical results.

Authors: Soraya Siti , Herawati Baiq Candra , Negara Habib Ratu Perwira
Published: April 2021

Economic growth is a measure of the welfare of the people in an area. Economic movement is characterized by the number of goods and services produced. The high amount of goods produced and the services used are of course strongly influenced by the amount of available capital, the labor involved, and the level of technology used. The measuring instrument or a reflection of economic growth is the Gross Regional Domestic Product (GRDP). The purpose of this study is to model economic growth in NTB in 2018. In this study, GRDP modeling was carried out using the Bayesian Spatial approach. Based on the results of testing the spatial dependency and spatial heterogeneity, it shows that there is a spatial dependence on the GRDP of districts / cities in NTB Province.. From the analysis conducted, it was found that  was positive and insignificant at the 10% level. The parameter estimation results show that the number of workers, the value of capital and the number of workers weighed are variables that have a significant effect on the model. Thus the GRDP of an area in West Nusa Tenggara is influenced by the number of workers, the value of capital and the total labor weight and the GRDP of other surrounding areas.

Published: April 2021

Sentiment analysis is an analysis with an objective to identify like, dislike, comments, opinion, or feedback on certain content which will be categorized into positive, negative, or neutral. In general selection, sentiment analysis widely known to be used to predict the winner on election process. This method tries to dig the people sentiment on their governor candidates during election, whether it’s positive, negative, or neutral opinion. The output of the positive sentiment is related to people acceptance towards one of the election nominee. That statement usually applied as a base reference for determining the result of the election process. In sentiment analysis, the importance of its fuzzy logics must be considered. Each of the people statement is assumed to have the level of positive, negative, or neutral percentage. The concept of fuzzy logic is developed and applied on one of this text mining method. This research is focusing on comparison analysis and fuzzy logic application in sentiment analysis method. Two method which discussed in this research are Fuzzy Naïve Bayes and Sentiment Fuzzy with convolutional neural network. This research is applied on PILKADA of Solo and Medan district case study. The data of the people opinion are acquired from twitter and collected on September 2020 to December 2020. The two methods which mentioned before are implemented on the acquired data and the output of these method application then compared. The conclusion of this research suggest that different approach will resulting in different output.

Mathematics is seen by some students as a subject which is not easy to learn. Thus, they need someone who can make mathematics easy, in this point, a teacher. Teachers as instructor are needed to be more innovative in developing instruction that can encourage students to get an ideal learning experience. Not just regarding approaches, teaching materials, and strategies, yet additionally needs to focus on the learning environment which promotes the learning process. One of the framework that offers learning which takes into a supportive learning environment is the Productive Pedagogies Framework. The purpose of this study is to look at the implementation of learning that utilized the Supportive Classroom Environment dimension of the Productive Pedagogies Framework. This study used qualitative method. There were 33 grade VII students (boys and girls) on average age of 13 years old from one of the Junior High Schools in Bandung participated in this study. The research findings revealed that (1) implementing Supportive Classroom Environment can further encourage students in upper group to achieve more optimal learning outcomes; (2) This learning can be said to encourage middle group students to get optimal learning outcomes; (3) This learning has not been able to encourage students in lower group. We concluded that implementing Supportive Classroom Environment can further encourage students in upper and middle groups.
The origins of the ukrainian economy vulnerability to negative financial-economic shifts
Authors: Drobyazko Mariya
Published: April 2021

The article is devoted to the problem of ensuring the economic’s long-term stability in respons to external and internal cyclical disturbances. Its conceptual basis is the vision of the critical importance of the human capital reproduction and accumulation of to ensure the sustainability (resistance) of economic growth, which echoes the work of D. North, D. Wallis and B. Weingast. Accordingly, the initial hypothesis underlying the article assumes that those countries that rely on a strong social sphere that has a diversified system of funding sources are more resistant to negative disturbances. In particular, the high demand for qualified personnel makes economically justified large-scale private investment in human capital, which provides a strong resource base for the development of education and medicine. Decent living standards required for normal socialization lead to high levels of social standards, which in turn supports the breadth of the competitive field, a critical parameter needed to maintain development potential (rather than just growth) in unfavorable macroeconomic conditions.

Authors: DeRobertis Michelle , Ferrell Christopher E. , Lee Richard W. , Moore David
Published: April 2021

Public, fixed-route transit services most commonly operate on public streets. In addition, transit passengers must use sidewalks to access transit stops and stations. However, streets and sidewalks are under the jurisdiction of municipalities, not transit agencies. Various municipal policies, practices, and decisions affect transit operations, rider convenience, and passenger safety. Thus, these government entities have an important influence over the quality, safety, and convenience of transit services in their jurisdictions. This research identified municipal policies and practices that affect public transport providers’ ability to deliver transit services. They were found from a comprehensive literature review, interviews and discussions with five local transit agencies in the U.S., five public transportation experts and staff from five California cities. The city policies and practices identified fall into the following five categories: Infrastructure for buses, including bus lanes, signal treatments, curbside access; Infrastructure for pedestrians walking and bicycling to, and waiting at, transit stops and stations; Internal transportation planning policies and practices; Land development review policies; Regional and metropolitan planning organization (MPO) issues. The understanding, acknowledgment, and implementation of policies and practices identified in this report can help municipalities proactively work with local transit providers to more efficiently and effectively operate transit service and improve passenger comfort and safety on city streets.

KCNN4 promotes the progression of lung adenocarcinoma by activating the AKT and ERK signaling pathways
Authors: Xu Ping , Mo Xiao , Xia Ruixue , Jiang Long , Zhang Chengfei , Xu Haojun , Sun Qi , Zhou Guoren , Zhang Yijie , Wang Yongsheng , Xia Hongping
Published: April 2021

BACKGROUND: Potassium channels, encoded by more than seventy genes, are cell excitability transmembrane proteins and become evident to play essential roles in tumor biology. OBJECTIVE: The deregulation of potassium channel genes has been related to cancer development and patient prognosis. The objective of this study is to understand the role of potassium channels in lung cancer. METHODS: We examined all potassium channel genes and identified that KCNN4 is the most significantly overexpressed one in lung adenocarcinoma. The role and mechanism of KCNN4 in lung adenocarcinoma were further investigated by in vitro cell and molecular assay and in vivo mouse xenograft models. RESULTS: We revealed that the silencing of KCNN4 significantly inhibits cell proliferation, migration, invasion, and tumorigenicity of lung adenocarcinoma. Further studies showed that knockdown of KCNN4 promotes cell apoptosis, induces cell cycle arrested in the S phase, and is associated with the epithelial to mesenchymal transition (EMT) process. Most importantly, we demonstrated that KCNN4 regulates the progression of lung adenocarcinoma through P13K/AKT and MEK/ERK signaling pathways. The use of inhibitors that targeted AKT and ERK also significantly inhibit the proliferation and metastasis of lung adenocarcinoma cells. CONCLUSIONS: This study investigated the function and mechanism of KCNN4 in lung adenocarcinoma. On this basis, this means that KCNN4 can be used as a tumor marker for lung adenocarcinoma and is expected to become an important target for a potential drug.

Published: April 2021

BACKGROUND: Altered cadherin expression plays a vital role in tumorigenesis, angiogenesis and tumor progression. However, the function of protocadherin 17 (PCDH17) in breast cancer remains unclear. OBJECTIVE: Our target is to explore PCDH17 gene expression in breast carcinoma tissues and its relation to serum angiopoietin-2 (Ang-2), carbonic anhydrase IX (CAIX) and % of circulating CD34+ cells in breast cancer patients (BCPs). METHODS: This study included Fifty female BCPs and 50 healthy females as control group. Cancerous and neighboring normal breast tissues were collected from BCPs as well as blood samples at diagnosis. PCDH17 gene expression was evaluated by RT-PCR. Serum Ang-2, CAIX levels were measured by ELISA and % CD34+ cells were assessed by flow cytometry. RESULTS: PCDH17 was downregulated in cancerous breast tissues and its repression was significantly correlated with advanced stage and larger tumor size. Low PCDH17 was significantly correlated with serum Ang-2, % CD34+ cells and serum CAIX levels. Serum CAIX, Ang-2 and % CD34+ cells levels were highly elevated in BCPs and significantly correlated with clinical stage. CONCLUSIONS: PCDH17 downregulation correlated significantly with increased angiogenic and hypoxia biomarkers. These results explore the role of PCDH17 as a tumor suppressor gene inhibiting tumor growth and proliferation.
Correlation of paretic knee extension strength with gait speed after stroke: A meta-analysis
Authors: Bohannon Richard W.
Published: April 2021

BACKGROUND AND OBJECTIVE: Numerous studies have addressed the relationship between paretic knee extension strength and comfortable walking speed after stroke. However, the correlations reported are highly variable. This review sought to summarize the correlational data using meta-analysis. METHODS: Relevant literature was identified via a search of 3 bibliographic databases. Articles were screened and perused for inclusion. Included articles were examined for information on the sample studied, procedures for measuring strength and gait speed, and correlations reported between the 2 variables. Meta-analysis was used to calculate a summary correlation. RESULTS: Of 299 unique articles, 18 met inclusion criteria. Articles were diverse in regard to samples studied, procedures described, and correlations reported. Meta-analysis using data from all included studies revealed a summary correlation of 0.51. For studies using hand-held or isokinetic dynamometry, the summary correlation was 0.46 and 0.59 respectively. CONCLUSIONS: This study provides a better indication of the correlation between paretic knee extension strength and comfortable gait speed than individual studies. The correlation is high enough to provide support for the routine measurement of paretic knee extension force for individuals who have experienced a stroke.

SEROMA AFTER TENSION-FREE INGUINAL HERNIA REPAIR – OUR EXPERIENCE
Authors: Nigam Vinod Kumar , Nigam Siddarth
Published: April 2021

Seroma Is a collection of fluid called serum that gets collected at the site of inguinal hernia surgery. It is common after inguinal hernia repair with a mesh. Usually seroma develops after 7 to 10 day of operation but can develop even earlier depending upon the amount of tissue dissection. More the dissection more the chances of development of seroma. The fluid in seroma is usually clear or straw colored. Seroma generally does not require any treatment; it disappears by absorption by body tissues within few weeks. Large seromas may require repeated aspiration. To avoid developing seroma after inguinal hernia surgery is to do minimal tissue dissection and avoid dead space formation. We operated 400 cases of inguinal hernia by a modified Lichtenstein tension-free procedure called NICH (Nigam’s inverted curtain hernioplasty) our incidence of development of seroma was 1.5% against international incidence of 7% which is a real low incidence. We have discussed the ways to avoid formation of seroma after open inguinal hernioplasty.

Keywords: dead space, dissection, inguinal hernia, Lichtenstein, mesh, NICH, seroma.

How To Prevent Inguinodynia - After Tension-Free Inguinal Hernia Repair – Our Experience
Authors: Nigam Vinod , NIGAM Dr. SIIDDHARTH
Published: April 2021

Abstract:

Inguinodynia is persistence of pain for more than 3 months after inguinal hernia operation. Chronic pain may be associated with hyperesthesia or hypoesthesia. This pain may be mild, moderate or severe. Inguinodynia may even effect quality of life. Pain may resolve on its own or after conservative treatment. Sometimes it persists and conservative methods fail then various other modalities of treatment are considered including re-exploration and neurectomy. We performed all 396 inguinal hernia repair by a modified Lichtenstein tension-free procedure. In our series of 396 cases inguinodynia happened only in 3 cases, a real low incidence. Some researchers have reported the incidence of inguinodynia as high as 19 percent 1 year after operation. No case required re-exploration, removal of mesh or neurectomy in our series.

Authors: Kandavalli Lakshmi Keerthi , Pavuluri Aravind Kumar , S Musalaiah S.V.V.
Published: April 2021

Aim: This study aimed to compare the effect of low-level laser therapy irradiation with two different wavelengths after osteotomy site preparation on the stability of dental implants.

Materials and Methods: The current study is a double-masked, randomized clinical trial. A total of seven patients of age 25 to 55 years were assigned randomly into two groups. Group I: Osteotomy site irradiated with low-level laser therapy of wavelength 940nm. GROUP II: Osteotomy site irradiated with low-level laser therapy of wavelength 660nm.

Implant stability was measured after implant placement using the Penguin RFA device. Bone formation was assessed with Cone Beam Computed Tomography.

Results: The current trial results showed that low-level laser therapy aided in bone formation around the implants, but there is no significant difference between the two different wavelengths.

Conclusion: Implant stability increased in both groups, but no difference is observed among the groups. Hounsfield units indicating bone formation improved in both the groups with no pronounced difference between the groups. All 14 implants were stable, thus indicating that low-level laser therapy aids bone formation, but the wavelength difference had no significant impact.

Keywords: Low level laser therapy, Implant Stability, Resonance frequency analysis

Background: Schizophrenia is a chronic disorder with positive and negative symptoms, and insight is involved in its prognosis. Illness management is considered a skill and strategy for patients with some mental disorders. Objectives: We aimed to investigate the illness management effectiveness on the positive and negative symptoms and insight in schizophrenic patients. Materials & Methods: This study was a quasi-experimental, controlled study with a pre-test-posttest design. The study population included all schizophrenic patients admitted to the Shafa Hospital, Guilan Province in the North of Iran, from March 2019 to April 2020. The sample included 30 schizophrenic patients selected using the convenience sampling method and was divided into 2 groups (experimental and control groups), with 15 patients in each group. For data collection, the scale for the assessment of negative symptoms, the scale for the assessment of positive symptoms, and the scale to assess unawareness of mental disorders were used before and after the intervention. Illness management was performed on the experimental group as group therapy. The control group did not undergo any concomitant intervention. Data analysis was performed in SPSS software version 24 using the univariate analysis of variance in normal distribution and the non-parametric Kruskal-Wallis test for the variable which didnchr('39')t follow the normal distribution.. Results: Results indicated that illness management could effectively alleviate the positive and negative symptoms and improve the insight in schizophrenic patients (P<0.01). Conclusion: Illness management was influential on the positive and negative symptoms of schizophrenia. Thus, this therapeutic modality can be used as an effective technique in hospitalized schizophrenic patients.

Objective: In recent decades, the relationship between personality traits and attitudes toward substance use has attracted much attention. Accordingly, evidence suggested a significant direct relationship between personality traits and the tendency to substance use. However, studies on the relationship between the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM–5) (PID-5) PID-5 model, personality pathology, and the tendency to substance use are scarce. Moreover, our survey revealed that no studies had been conducted in this respect in Iran. Drug abuse, as a prevalent condition, is of numerous etiologies, one of which is maladaptive personality traits. The present study aimed to investigate the relationship between maladaptive characteristics and the severity of personality disorders in predicting substance use tendency. Methods: This descriptive research was conducted from January 2018 to December 2019 in Tehran City, Iran. The statistical population of this study consisted of 300 healthy individuals with substance abuse disorder referring to substance dependence treatment centers who were selected by the convenience sampling method. Data gathering tools were the Personality Inventory for DSM-5-Brief Form (PID-5-BF), the Standardized Assessment of Severity of Personality Disorder (SASPD), and the Addiction Tendency Questionnaire. The obtained data were analyzed by correlation and stepwise multiple regression analysis methods using SPSS. Results: The current study results revealed that drug use tendency is significantly associated with personality traits. Among the maladaptive traits, antagonism had the highest correlation with drug use (0.45). Moreover, the obtained data indicated a low correlation (0.014) between the severity of drug tendency and personality traits, according to PID-5. Conclusion: The current study results revealed that drug use tendency is significantly associated with personality traits. Among the maladaptive traits, antagonism had the highest correlation with drug use (0.45). Moreover, the obtained data indicated a low correlation (0.014) between the severity of drug tendency and personality traits, according to PID-5.

Objective: The present study aimed to compare the effects of the non-computerized training package of Working Memory (WM) and selective attention with Captain’s Log software on the components of WM. Methods: This was a quasi-experimental study with a non-random targeted sampling method, and pre-test, post-test, follow-up, and a control group design. A sample of 150 cases aged 13 to15 years diagnosed with Temporal Lobe Epilepsy (TLE) referring to neurology clinics was selected and randomly divided into two case groups (n=15/group) and a control group (n=15). The non-computerized package was performed in 15 one-hour sessions for 4 weeks in the first case group. Besides, the computerized package was provided in 15 sessions (45 minutes each) for 4 weeks in the second case group; however, the control group received no training. All WM components were examined in the pre-test, post-test, and follow-up (3 months after post-test) steps in all study groups. Results: The repeated-measures Analysis of Variance (ANOVA) data indicated a significant difference in the mean scores of the components of WM in the first case group, compared to the second case group and the controls (P<0.05). Conclusion: The non-computerized package of WM and selective attention were significantly more effective on the WM components, compared to the Captain’s Log computerized package.

Objective: Numerous children with Obsessive-Compulsive Disorder (OCD) either have no access to its main treatment, i.e. Cognitive Behavioral Therapy (CBT), or fail to respond to it. Cognitive Bias Modification of Interpretation (CBMI) is a novel and promising intervention that targets the incorrect interpretation of intrusive thoughts and impulses, i.e. the characteristics of OCD. The present study aimed to determine the effects of CBMI in children with OCD for the first time. Besides, we evaluated the possibility of online implementation of this intervention. Methods: A sample of 35 children with OCD (aged 7-12 years) were randomly assigned to two study groups. The experimental group (n=18) received CBMI and the controls (n=17) received placebo treatment. Interpretation bias and OCD severity were assessed at pre-test, post-test, and 2-month follow-up stages, using the Obsessive Compulsive Inventory-Child Version (OCICV), Obsessive Beliefs Questionnaire-Child Version (OBQCV), and Ambiguous Scenarios Task (AST). The present study results were analyzed using two-way repeated-measures Analysis of Variance (ANOVA) and Paired Samples t-test. Results: The collected findings demonstrated that after receiving CBMI, children’s propensity to positively interpret ambiguous situations was increased, their tendency towards negative interpretation and OCD severity was also decreased. There was no such significant change in the control group. Furthermore, the effects of CBMI was sustained at the 2-month follow-up step. Conclusion: This study provided preliminary evidence that suggests CBMI is capable of modifying interpretation bias in children with OCD, can reduce the severity of their disorder, and works as an online intervention. This brief and inexpensive intervention could be considered as an auxiliary or standalone treatment for OCD in children.

Activated carbon was prepared from Terminalia catappa shells using microwave asissted KOH activation. The ratio of mass percentages of Terminalia catappa and KOH were 4:1, 4:2, and 4:3. Terminalia catappa based activated carbon was prepared by KOH activation at the room temperature for 24 hours and followed by microwave irradiation at the out put power of 630 Watt for 20 minutes. The physical properties of activated carbon i.e. surface morphology, micro structure, and BET surface area were characterized by electron scanning microscope, X-ray diffraction and N2 adsorption-desorption isotherm at 77K, respectively. The highest BET surface area was 312 m2/g with adsorption of activated carbon towards methylene blue by 84.4 mg/g. The BET surface area was directly correlated with the stack height (Lc) of the activated carbon.

A preliminary study has been conducted on supercapacitor carbon-electrode monolith prepared from teak leaf waste. The objective of this study is to know the electrochemical cell capacitance from carbon materials. The production of carbon electrode began with pre-carbonization process at 2500C for 2.5 hours, then proceeded to chemical activation using KOH activator with concentration of 0.3 M. Hydraulic Press was used with pressure at 8 ton to form the monolith. Then, the density was measured the carbonization. After that the sample was activated using CO2 gas at 8500C burning temperature. Next after the carbonization, the density was measured by collecting mass, diameter and thickness data of the electrode. The specific capacitance was measured using Physics CV UR Rad-ER 5481 which is controlled by a cyclic voltammetry software with the potential window width of 0 – 0.5 V and at a scan rate of 1 mV/s. The best density results obtained were 0.853 g/cm3 before carbonization for sample code C24 and 0.605 g/cm3 after carbonization for sample C30. The specific capacitance was found at 113.20 G/g for C32 and C38 electrodes

The fish bone waste treatment program for the application of useful products, specifically as a natural ingredient of the drinking water filter.This program works with coastal communities in terms of providing raw materials. This program is a social innovation from the transfer of knowledge of the university's inventors to the coastal communities, in the aim to maintain and improve the cleanliness of the environment, which is then applied for the purpose of developing a water filter system. The contribution of this organic product is useful for Small, Micro & Medium Enterprises engaged in the production of food and beverages, as well as donations for cosmetic and health products to industries, as well as donations to policy development, through the application of environmental physics and science development to product development, pre-commercialization and commercialization (social engineering & manufacturing). The involvement of coastal communities in utilizing their waste is to achieve the empowerment of coastal communities, emphasizing community involvement to learn and cooperate for future development goals. Prior to the formation of this program, the community who failed to take care of its waste often had the waste dumped into the sea, rivers and garbage collection sites. The disposal causes the form of pollution problems that invite various dangerous diseases and cause the community environment to be clean, smelly and diseased. The results of the research have been done, Fish bone waste can be processed to be a product of water filter system resulting from fish processing industry, which contains high calcium. Fish bones are very rich in calcium that is needed by the human body, because the main elements of fish bones are calcium and phosphorus. The use of fish bone calcium is widespread such as overcoming coastal pollution and other environments in the disposal of heavy metals such as Zinc (Zn), Copper (Cu), Lead (Pb), and Iron (Fe).

Authors: Supriyanto Amir
Published: April 2021

The electrical characteristics of cassava peel can be detected by using a pair of electrodes, Cu and Zn. Measurement of electrical characteristics is done when the cassava peel is given a 5 watt LED load and when the load is removed. Cassava peel are used in two different ways: fermented and non-fermented. The electrolyte cell used consisted of 20 cells, assembled in three different types: 20 series, 10 series with 2 parallel, and 5 series with 4 parallel. The volume of each cell's paste is 200 ml. The measurement results show that the 20 series circuit produces the greatest electrical voltage, but the electric current is small and the resistance is large. While the series with 20 cells and 5 series with 4 parallel obtained maximum power. The cassava peel which were fermented for 72 hours can increase the electrical power generated from the three types of circuits.

Published: April 2021

Synthesis of Lithium Manganese Oxide (LiMn2O4) for Lithium Ion Battery Cathodes with Solution Method has been conducted. This experiment was carried out using the solution method. In this study, the synthesis was carried out by varying the calcination temperature. The raw materials used were Lithium Acetate (C2H3O2Li), Manganese Acetate (C4H6MnO4.4H2O), Hydrochloric Acid (HCl), and Ethanol (C2H5OH) as solvents which were dissolved to become LiMn2O4 precursors. Synthesis was carried out at calcination temperatures of 600oC, 700oC and 800oC, for 4 hours then pounded with a mortar until smooth. The characterization includes: The results of the STA test at 280oC-380oC showed a mass decrease of 11.9973% due to the release of mass of water vapor and decomposition of C4H6MnO4.4H2O raw material. XRD analysis shows that the increase in peak temperature of the LiMn2O4 phase intensity is getting sharper, the peak showing the impurity Li2O phase decreases. SEM analysis results show that the higher the calcination temperature, the larger the particle size is formed, because in the calcination process the densification process occurs.
