Authors: Rahman Md Sydur , Ahmed Boshir
Published: September 2022

Psychiatry is an interdisciplinary field that focuses on a major public health concern. The following threats represent a significant risk to the mental health of anyone who is exposed to them. Various things might have an impact on both a person's physical and financial health. Psychiatric treatment can raise the likelihood of getting a mental disorder. Schizophrenia is a devastating mental condition that predominantly affects women. It is more prevalent in both male and female. Mentally sick individuals are more likely to engage in antisocial behavior which results in social behavioral distortion. As a direct result, societal concerns that were already evident have grown considerably more prevalent. According to global data, anxiety, drugs misuse, hazardous behavior, arrogance, suicidal thoughts, depression, disorientation, and consciousness are widespread among 20 to 30 years adults. These individuals are continuously searching for something new, which can be detrimental to their mental health because it makes them less stable. 

A machine learning classifier has been predicted to classify the appropriate extracted features after applying Support Vector Machine (SVM) classifiers for various no-linear kernels, taking into account all the critical elements for psychiatry that have been stated. An unequal history of mental diseases has climbed from 10.5 percent in 1990 to 19.86 percent in 2022, according to Adult Prevalence of Mental Illness (AMI) 2022, and psychiatry currently accounts for 14.3 percent of yearly global mortality (approximately 8 million).

Published: September 2022

The macrofungi diversity in Akwa Ibom State, Nigeria has been inadequately sampled and never documented; this situation makes the status of macrofungi in the State unclear. It is from this reason that this study was necessitated. A total of 60 species of wild macrofungi belonging to 25 families we documented during the period of this study (April to July 2021).  Agaricaceae family recorded the highest number of species (12), followed by Polyporaceae (10), Psathyrellaceae (5), Marasmiaceae (4), Amanitaceae (3), Gomphaceae, Lycophyllaceae, Physalacriaceae, Hymenochaetaceae, Gamodermataceae andStrophariaceae recorded 2 species each. Pluteaceae, Stereaceae, Bondarzewiaceae, Schizophyllaceae, Entolomaceae, Cortinariaceae, Pleurotaceae, Dacrymycetaceae, Auriculariaceae, Tricholomataceae, Hygrophoraceae, Hydnangiaceae, Tubiferaceae and Lycoperdaceae recorded 1 species respectively. Out of the 60 macrofungi recorded, 36 species (60.00%) were non-edible, 13 species (21.67 %) were edible, 2 (3.33%) were choice edible and 2 (3.33%) edible but not recommended respectively. 1 species (1.67%) each were poisonous, psychoactive, edible while young, not recommended, non-poisonous but leathery, edible but shows allergic reactions in some individuals and unknown edibility status. Analysis on the growth substrate of the macrofungi species found revealed that; 32 species (53.33%) grew on dead wood, 25 species (41.67%) on soil, 2 species (3.33%) on living tree trunk and 1 species (1.67%) on decaying organic matter. The list and inventory provided by this study will give baseline information that will be needed in the assessment of changes that may occur in wild macrofungi diversity in Akwa Ibom State, Nigeria. The rich diversity of wild occurring macrofungi in Akwa Ibom State offers huge economic life for the local inhabitants in terms of nutriton, health and medicine as well as ecosystem stability at large. Inclusion of macrofungi biodiversity conservation in Akwa Ibom State and Nigerian forest management policies will be an appropriate step towards conservation of these wild macrofungi.

Published: September 2022

The human epidermal growth factor receptor-2 (HER2), which is expressed in large amount in 20%-30% of breast cancer patients, is associated with disease recurrences, shortened disease survival, and bad prognosis. The aim of this study is to evaluate the expression of (Her2/neu) receptor as a diagnostic and prognostic marker in Invasive Ductal Breast cancer in Sudanese female patients. The study was performed on 35 archival paraffin blocks previously diagnosed as invasive ductal breast cancer (IDC), then a second diagnosis was done using IHC staining (Her2/neu). The obtained information is arranged in a standard master sheet, then analyzed using a statistical package for social science (SPSS) version 20 computer program. The age 30-45years was the most frequent age group 48.6% (17/35), followed by 46-60 years 40% (14/35). The majority of samples were grade III 74.3% (26/35) and the samples of grade II were 25.7% (9/35). the majority of TMA results were positive for Her2/neu receptor 65.7% (23/35) and the negative results were 34.3% (12/35) the majority of TMA score were (+) 31.4% (11/35), followed by (++) 17.2% (6/35), then (+++) 11.4% (4/35), then (++++) 5.7% (2/35), and the negative result were, 34.3% (12/35). There was a significant relation between H&E diagnosis with TMA result for Her2/ neu diagnosis that the P-value (0.0002). There was an insignificance relation between H&E diagnosis of grades with TMA results for Her2/ neu diagnosis that the P-value (0.08). In conclusion, HER2 is over-expressed in 65.7% of the patient while internationally it is over-expressed in 15-30%. This provides valuable prognostic and predictive implications in order to choose the suitable treatment for the patients.

Project Investment Analysis: Case Study of Installation Additional Offloading Pump at B-Field to Recover Oil Production
Authors: Mahfudz Mochamad Sholahudin , Prasetyo Ahmad Danu
Published: September 2022

Oil and gas production in Indonesia keeps declining while consumption increases, resulting in Indonesia being a net oil importer since 2004. The problem that is faced by many producers right now is the mature field with an aging production facility with frequent unplanned shutdowns that could jeopardize production. If not responded to promptly and adequately, the field could lose its production. This is one of the challenges that PT ABC are facing. This study will present an investment project analysis to procure additional permanent offloading pumps at Field-B PT ABC to help revitalize the field after an unplanned shutdown. The additional offloading pump is intended to speed up wells' potential recovery and minimize potential loss after shutting down. Two scenarios are evaluated for the additional offloading pump: buy case or lease case. The investment study is performed by exercising the business situation analysis and then using discounted cash flow (DCF) method for the financial feasibility. From the business situation analysis of PESTEL for external and VRIO method for internal analysis, both analyses suggest the external and internal aspects support the investment project of having the additional offloading pump. The DCF analysis is performed using the Production Sharing Contract (PSC) scheme applied to PT ABC. For the buy case, the Net Present Value (NPV) is 0.89 million $ with Monte Carlo Simulation showing the possibility of having a negative NPV is 7%. For the lease case, the NPV is 2.32 million $ with Monte Carlo Simulation showing the possibility of a negative NPV of 0%. Based on the DCF parameter analysis then, it is suggested to the management of PT ABC to invest in additional offloading pumps at Field-B by using the lease option, which shows better NPV.
Impact of Total Quality Management (TQM) on the Competitive Priorities of Lebanese Industries
Authors: Jbeily Ahmad Houssami
Published: September 2022

Total Quality Management (TQM) techniques significantly impact the competitive priority in terms of cost, quality, time, and innovation of Lebanese businesses. Changing an organization's operational strategy is highly dependent on top management commitment as changing employees' behavior is challenging without the cooperation of the business's senior management. Both descriptive and cause-and-effect methods were used in this research, and data was gathered from Lebanon's businesses in May 2022 via a questionnaire. The survey was sent to more than 200 managers and supervisors, but only 184 answered. First, a correlation between variables was established and then a hypothesis was evaluated using multiple regressions to determine the tool's validity and reliability. According to the findings, Lebanese enterprises strongly apply TQM and competitive priority factors, and these variables have significant correlations. The competitive goals of Lebanese enterprises are also influenced by top management commitment, employee training, engagement, and continuous improvement.
Project Investment Plan Valuation Using Discounted Cash Flow Analysis (Case Study of LLP Compression Project Investment Plan at Tango Field, Mehacca Block)
Authors: Primasari Indah
Published: September 2022

This article performs a valuation analysis of LLP Compression in project investment plan at Tango Field in Mehacca Block. The LLP Compression investment project plan is currently under consideration for a Final Investment Decision (FID). The analysis is conducted by using quantitative methodology approach to evaluate 2 project scenario based on its cash flow. The outcome of financial valuation could assist decision maker in the company, in determining whether the project is economically profitable, whether it should be executed, what scenario can generate maximum economic profit for the company, and also what financial factor affecting LLP Compression Project cash flow that should be managed to avoid negative financial results and to forecast project likelihood of success.
For DCF analysis, with company discount rate at 10.2%, the Net Present Value (NPV) result is 1.12 Million USD for Scenario 1 and 0.91 Million USD for Scenario 2. Internal Rate of Return (IRR) for both scenarios are higher than company’s discount rate. Payback Period for both scenarios are also the same in year 2026, or 2 years after production. Profitability Index (PI) for Scenario 1 is slightly higher than Scenario 1 amounting at 1.07, while PI for scenario 2 is 1.03. All of the parameters from DCF gives positive result more than expected return, with scenario 1 that provide better value than scenario 2.
Monte Carlo simulation is also used to provide a likelihood of having a negative NPV. The result is that both scenarios have probability negative NPV amounting 28% for scenario 1 and 30% for scenario 2. Based on Monte Carlo Simulation result, scenario 1 has slightly lower probability of generating negative NPV than Scenario 2.
Sensitivity analysis is also being used to look how large NPV project varies if the parameter inputs are changed. Four parameters tested with assumption change at ± 25% from original condition. Based on sensitivity analysis, it is observed that Gas Production, Gas Price are the most sensitive parameter for both scenarios of LLP Compression project.
In summary, the LLP Compression Project investment plan is feasible to be executed for both scenarios, with scenario 1 provides higher economic profit than scenario 2, and it also generates slightly lower probability negative NPV than scenario 2. Since LLP Compression Project has probability of gaining negative NPV based on Monte Carlo Simulation Result, hence several strategies to minimize project risk exposure are required to be determined before project execution.

Authors: Syahrial Teuku Riza , Nusraningrum Dewi
Published: September 2022

Soekarno-Hatta International Airport is one of the airports managed by PT Angkasa Pura II as the airport operator. At Soekarno-Hatta Airport there are several PLTS (Solar Power Plant) facilities, one of which is located at Terminal 3 of the Airport. There are 2 PLTS locations in Terminal 3, namely PLTS with a capacity of 2Å~60 KWp in Domestic Terminal 3 and a capacity of 2Å~60 KWp in International Terminal 3. Technically, based on the report on the activity, the PLTS production value has decreased in performance and production in 2020. The purpose of this paper is to calculate the OEE value, identify Six Big Losses, and analyze maintenance and repair data as an effort to implement the TPM (Total Productive Maintenance) concept for improve the performance and production of PV mini-grid. The method used in this paper uses the calculation of the value of OEE, Six Big Losses and causal analysis using a fishbone diagram. Based on the results of calculations at international terminal 3 the OEE value is 95.59% and in domestic terminal 3 it is 94.56%. At the airport, the expected availability value is above 99.18%, but at the domestic Terminal 3 it has an availability value of 96.93%. Regarding the calculation of the value of Six big losses, the largest percentage is in Reduce Speed Losses, where the value for International Terminal 3 is 95.71% and Domestic Terminal 3 is 94.35%. Reduce Speed Losses related to the operation function of PLTS not running well so that the performance and electricity production produced by PLTS is not as expected.

Authors: Jabak Hasan
Published: September 2022

In recent years, the global economy has been going through a severe downturn, which has led to the failure of several banks and corporations as well as a wide range of other financial problems. During those difficult times, its financial reports received a great deal of attention in many nations. The greatest worry was over the quality of such reports as well as the volume of their reporting and to what extent do they impact the worth of a particular firm or organization. The reporting of financial information has a significant impact, not only on the global financial markets but also on the financial information of firms. This is where the audit committee comes in; it is the body that is responsible for the reporting of financial information. The data will be gathered during the distribution of the survey via the use of google forms with a sample size of three hundred and fifty respondents for the purpose of data collection. For the sake of statistical analysis and the validation of hypotheses, the data that was obtained will be evaluated using google forms. It was determined in this study how many different features of AC impact financial reporting made by Lebanon-based firms. A survey was administered to 350 people as part of this study in order to gather data. Statistical software was used to examine the relationship between the independent variables (size, experience, and independence of the AC) and their dependent variable (quality of financial reports of companies) on the one hand.

Iron Deficiency Anemia Treatment in Pregnancy
Authors: Mahayasa Putu Doster , Winata I Gde Sastra , Setiawan William Alexander
Published: September 2022

Around 1.5 billion people worldwide, iron deficiency anemia affects about 50% of the anemia cases. Anemia in pregnancy often occurs due to iron deficiency which can affect the condition of both the mother and the fetus. Serum ferritin measurements have the highest sensitivity and specificity for the diagnosis of IDA unless there are underlying inflammatory conditions. In pregnant women, the lower threshold value for hemoglobin (Hb) is <11 g / dL in trimester I and III, and <10.5 g / dL in trimester II. A Hb concentration <10 g / dL indicates clinically significant anemia during the puerperium. Oral iron therapy is given as a first-line treatment for iron deficiency anemia. Although current data are limited, intravenous (IV) iron therapy is an alternative therapy option in patients who do not respond to oral iron therapy, develop side effects, do not adhere to oral iron treatment, have very low Hb concentrations and require immediate treatment for severe anemia cases. Apart from giving iron, red blood cell transfusion is also an option for treating iron-deficiency anemia in pregnancy.
Magnesium Sulphate and Nifedipine in Management of Preterm Premature Rupture of Membranes
Authors: Aryana Made Bagus Dwi , Winata I Gde Sastra , Setiawan William Alexander
Published: September 2022

Premature rupture of membranes (PROM) is defined as rupture before delivery that can occur at any gestational age. If it occurs before 37 weeks of gestation, it’s called Preterm Premature Rupture of Membrane (PPROM). PROM is a condition that still occurs in both developed and developing countries and cause a serious threat to the fetal and maternal well-being if not managed properly. Conservative management is chosen in PPROM until the fetus is viable, consist of hospitalization, assessment of sign of infection, well-being of the fetal and maternal. Spesific treatment includes the administration of corticosteroid, antibiotics, and tocolytics. Tocolytic agents that are widely used as first-line agents are magnesium sulphate (MgSO4) and nifedipine, one of the Calcium Channel Blocker (CCB) groups. MgSO4 and nifedipine both have an effect in reducing myometrial contractility. MgSo4 also has a neuroprotective effect in PPROM less than 31 weeks if there is a threat of delivery within 24 hours. Meta-analysis related to the use of these two agents in PPROM is still subject to differing result. Some studies have shown nifedipine is considered to have milder side effect than MgSO4, more easily tolerated by oral administration, and more affordable. However, some studies have shown that the two agents have the same efficacy. Other studies have shown no significant benefit in administering nifedipine to neonates or prolong pregnancy in women with PPROM without contractions.
Orbit of an Extended Body in a Repulsive Field: Toward an Electromagnetically Bound Nucleus
Authors: Selke David Lloyd
Published: September 2022

The point particle assumption is unjustified. Inspired by Randell Mills’ classical extended electron model, we ask whether an asymmetrically positively charged ring can orbit a positive point charge in a stable manner. We numerically simulate this system up to five million time steps and find that the point remains inside the ring. The ring and point represent two simplified protons that orbit under repulsion, a behavior inconceivable with point charges, but which may occur in nature. The simulation source code is provided.

This study aims to determine whether cash turnover and receivable turnover have effects on profitability. The research was conducted at manufacturing companies listed on the Indonesia Stock Exchange in 2017-2019. This study used a purposive sampling method, with the number of 55 companies each year, therefore the total sample is 165. The statistical method uses multiple linear regression analysis with t statistics hypothesis testing. The results of this study state that cash turnover has a significant positive effect on profitability. That states, company’s effectivity in managing its cash to generate revenue or sales is very impressive. Contrariwise, receivable turnover has a negative and significant effect on profitability. That states, high levels of receivable can reduce the profitability because the amount of receivable owned is small, which means the credit sales made are low, thus sales volume and profitability will decrease as well.

The purpose of this study is to investigate the impact of government trade barriers, consumer behaviours, and market demand on the business performance of small and medium-sized enterprises in Malaysia during the COVID-19 pandemic. The pandemic outbreak and subsequent lockdowns took a heavy toll on SME’s, affecting the economy, society, health, and the life cycle. SMEs have faced problems such as a labour shortage, a drop in demand, a shortage of raw materials, changes in consumer behaviour, and trade barriers imposed by governments through the movement control order (MCO). The data is gathered through the distribution of questionnaires, and the sample size is 107 respondents in the most affected states by the COVID19 pandemic. This study employs a quantitative approach, and it is analysed using regression. According to the findings of this study, changes in market demand have had a significant impact on the business performance of SMEs. It demonstrates that a drop in customer demand has resulted in a decrease in profit. The implications of this research are to encourage business actors to shift their market focus to satisfy demand and requirement changes, as well as to urge more severe measures to improve the performance of SMEs.

Para comprender las disputas entre los trabajadores de las ERTs argentinas sobre qué finalidad atribuyen a su empresa, abordamos la trayectoria de IMPA, una emblemática metalúrgica porteña. Nuestra investigación se basa en el trabajo etnográfico realizado por un período de tres años (2011-2013) en IMPA. Mostraremos que esas disputas condicionan la forma como cada ERT enfrenta sus tensiones y establece sus relaciones con el mercado o con el Estado.

Nowadays, electrically conductive polymer plays some important roles in the modern electronic devices because the crucial importance in telecommunication and biosensors. This type of materials offers an obvious decrease in the weight of the devices and it also has an environmental compatibility. A conductive polymer composite is promising alternative materials that has several advantages in the electronic applications currently. Polyester was used as a matrix, and copper –Tin /Zink inform of particulates with Copper short wires were considered electrically conductive fillers. The study prepared two groups (A and B) using different filler materials (Cu- Tin /Zink - Polyester and Cu- Tin /Zink –Cu- short wires / Polyester) with a weight fraction percentage of up to 50%. A composite processing method was slip casting to produce rectangular and cylindrical samples; after that samples were cured at room temperature for 48 hrs. Produced samples from both mixed were tested for density, ultimate tensile strength and scan electron microscope. AC conductivity test were performed for all samples using a frequency range from 50 Hz to 50 MHz to measure the dielectrically loss factor and electrical conductivity.  From the study, it has been found that filler powder almost proved better ultimate strength behavior, and the peak value was determined at 30% wt., while short wires above 40 % wt. can cause a dramatic reduction in tensile strength. The results revealed that short wires filler van improves the electrical conductivity by approximately 50%; when compared with using particulate filler only. The result from the microstructure showed that short wires with metals powder could provide a connected network for improving the conductivity in the polymer matrix.
“One might tweet just for money”: Organisational and institutional incentives for researchers’ social media communication and public engagement practices
Authors: Koivumäki Kaisu , Wilkinson Clare
Published: September 2022

The changing media landscape and proliferation of social media potentially increase agency amongst researchers to communicate individually. It also points to a need for studying science communication at an organisational level to understand how science communication activities can be collectively organised to have a substantial impact. Despite these changes, there are ongoing questions regarding the perceived value of science communication and the ways in which it can receive institutional support in credit-driven academic cultures. Therefore, this study set out to explore how incentives relate to researchers’ communication activity and how these can be influenced by digital communication contexts. This article presents a qualitative analysis of semi-structured interviews with 17 researchers and 15 communication professionals in Finland. Results indicate that academic leaders are in the key position to support organisational science communication culture, and their acknowledgement for science communication can be more effective than encouragement from in-house communication staff. This suggests that there may be a key gap vis-à-vis training in science communication and engagement which is targeted towards scientific and organisational leaders. The results also imply there is enduring value in communication activities featuring in periodical performance evaluation and that analytic data from digital media endeavours can form an intrinsic reward.

OBJECTIVE

To establish reference intervals for radial joint orientation angles in the frontal and sagittal planes in small-breed dogs and to compare them to those previously reported for medium- and large-breed dogs.

ANIMALS

Antebrachii of 30 skeletally mature, nonchondrodystrophic small-breed dogs were evaluated radiographically.

PROCEDURES

Orthogonal radiographs were retrospectively assessed to determine the anatomic medial proximal radial angle, anatomic lateral distal radial angle, anatomic cranial proximal radial angle (aCrPRA), and anatomic caudal distal radial angle (aCdDRA). The frontal plane angle, θ angle, and procurvatum were also calculated. The radial joint orientation angles determined were compared to those previously reported for medium- and large-breed dogs via a 1-sample t test.

RESULTS

Mean and SD values for anatomic medial proximal radial angle, anatomic lateral distal radial angle, aCrPRA, and aCdDRA were 80.86 ± 2.86°, 85.60 ± 1.74°, 87.99 ± 2.79°, and 83.08 ± 3.14°, respectively. The mean and SDs for frontal plane angle, θ angle, and procurvatum were 4.75 ± 2.46°, 11.88 ± 1.76°, and 16.79 ± 4.13°, respectively. aCrPRA and aCdDRA were significantly different when compared to previously reported radial joint angles for medium- and large-breed dogs.

CLINICAL RELEVANCE

Reference intervals for small-breed dog radial joint orientation angles were reported. Significant differences were identified for some joint orientation angles when compared to medium- and large-breed dogs. This small-breed reference interval reported can be utilized in planning of radial angular limb deformity corrective surgery, particularly when dogs are bilaterally affected.
Determinant Of Cash Holding

Published: September 2022

This study examines the effect of investment opportunity sets, net working capital, and profitability on cash holding. Cash holding is a liquid asset that has the benefits of supporting the company in the company's routine operational activities. The application of cash holding in a company can be influenced by investment opportunities, net working capital, and profitability. From 2016 to 2021, the research population consists of food and beverage companies listed on the Indonesia Stock Exchange. The research sample uses purposive sampling, so there are 15 companies. The study uses secondary data by collecting the company's annual report—the data analysis method used in Panel Data Regression utilising the Eviews version 9 application. The results indicate that the investment opportunity set, net working capital, and profitability simultaneously affect cash holding. Partially, only the location of investment opportunities affects cash holding. Meanwhile, net working worth and profitability do not affect cash holding.

Published: September 2022

This research aims to determine determinants of financial shenanigans and the differences in indications of the occurrence of financial shenanigans before and during the Covid-19 pandemic. Data of manufacturing industry listed on the Indonesia Stock Exchange (IDX) during 2019-2020 analyzed using descriptive statistical and logistic regression. The results show that financial targets, characteristics of the chief financial officer, and financial stability were simultaneously determinants of financial shenanigans. Partially, financial targets were the only determinants of financial shenanigans and no significant differences in indications of financial shenanigans before and during the Covid-19. Results of this study can be utilized by external auditors in detecting indications of financial fraud through changes in financial targets and can be an inform for investment decisions. Future study should consider continuing testing variables that do not have an effect by bringing up other calculation indicators and extend the time span either sample to predict financial shenanigans.

Estudio teórico/comparativo entre narración corta y microrrelato. Aportaciones desde la perspectiva narratológica
Authors: Álamo Felices Francisco
Published: September 2022

Partiendo de la concepción de la narratología de T. Todorov, en tanto que ciencia que abarca y sistematiza los conocimientos de la teoría del relato en sus diferentes aspectos, este estudio aborda un modelo de “representación/comparación” y análisis de los rasgos constitutivos y diferenciadores del cuento -esto es, sus estratos narrativos o los distintos planos de elaboración, organización y presentación que el texto viene a ofrecer- para plantear una precisa visión teórica y estructural de la relación textual cuento/microrrelato.
