Published: June 2020

The purpose of this study is to examine and analyse studies on article journals on the use of social commerce and how does it stimulate buying intention which lead to compulsive buying with the incurring of credit card debts among online users. Online users were then defined as social media-network users. It has been found through the article journals reviewed first; the more active online user was in using the social media-network platform the more likely will be involved in social commerce activities. Second, the more communications (customers reviews) transferred pertaining to purchasing; the higher motivation in inducing interest to buy products which can lead to compulsive buying. Thirdly, as subsequence to customers reviews, the offers of sales and promotions among companies who were using social commerce platforms increases the use of credit card and thus, incurred higher risk of becoming in debt towards financial instituions which can lead to psychological distress and unhappiness in workplace.

Published: June 2020

Public relations practitioners play a role in preserving the image and reputation of an organization. The existence of social media presents a great challenge for public relations practitioners to escape from negative perspectives which can affect the image and reputation of the organization. This is because information disseminated on social media, if not managed effectively, can bring damage to the image and reputation of the organization and can cause crisis. Thus, public relations practitioners play an important role in making sense of the crisis that is at stake for, in crisis management, they will be able to positively impact the organization while improving the reputation of the organization. The role of public relations is also seen not only during the crisis but also in the post-crisis phase. In this regard, this article will discuss the process of sensemaking of public relations practitioners in the post-crisis era.

Published: June 2020

Rapid development leads to a high demand and increased price for the basic construction materials like cement. This led the researchers to look for possible partial cement replacement by investigating the potential use of rice husk in making concrete hollow blocks. The researchers created concrete hollow blocks (CHB) at three different percentage of rice husk (RH) powder addition from 0%, 5%, and 10%. This study was intended to evaluate which works best in terms of compressive strength and density. The researchers created a total of 36 samples but only 12 were tested at ASTEC Materials Testing Corporation. Cost analysis, compression testing, and measuring of dimensions are the methods used to gather data. Results from the testing show that the mean compressive strength of the normal CHB (0%) is 76 psi compared to only 53 psi and 39 psi for CHB with 5% and 10% RH, respectively. The density of the normal CHB is 1.4319 g/cm3 while 1.2497 g/cm3 and 1.2822g/cm3 for CHB with 5% and 10% RH, respectively. In the cost analysis, the normal CHB costs ₱11.58 per piece, for CHB with 5% RH is ₱11.48, and for CHB with 10% RH is ₱11.37. Since the compressive strength of the normal CHB is greater than that of the CHB with pulverized rice husk, the researchers have concluded that a CHB unit is stronger and more resilient than a CHB with pulverized rice husk. Likewise, the mean density of the normal CHB is also greater than that of CHB with rice husk powder, it can be established that a CHB unit is more compact and rigid than the alternative. However, the addition of rice husk powder decreases the cost of CHB, therefore, CHB with RH is a more economical building material.

Published: June 2020

The fatality rate of children from ages one (1) to four (4) years old has increased due to mosquito-borne diseases, specifically dengue. Mosquitoes may transmit deadly diseases such as Yellow Fever, Dengue, Malaria, Filarial and Japanese Encephalitis through their bites, which may affect not only people but also the animals. Due to this, repellents such as mosquito coils must be used to avoid contact with mosquitoes. However, burning one inorganic coil is equivalent to smoking up to 137 cigarettes, which shows that the usage of mosquito coils are bad for the health since it can cause lung cancer, acute chronic health risks and may transmit infectious pathogens. In order to address the urgency and importance of such health issues, an experimental study was conducted using Neem and Papaya Leaves as primary components of a mosquito coil. The researchers aimed to substantiate the effectiveness of a mosquito coil using different botanical materials. This study is designed to protect and contribute to a healthier society by way of controlling if not combatting the growing population of mosquitoes, hence, lower the probability of people, especially children, to get infected with mosquito-borne diseases. The effectiveness of an organic mosquito coil, together with other factors such as cost, longevity, flammability, odor, durability, and effectiveness are evaluated in this study.

Published: June 2020

The millennials are increasing and dominating today’s workforce at an exponential rate. They are brewing with vigor, enthusiasm and determination to bring success to various organizations. Having said that, employers should give attention to this phenomenon and find ways in meeting the needs of this rising generation cohort to motivate and retain them. The aim of the study is to determine whether or not having the right motivation strategies for millennials will guarantee motivation and engagement from them, which in turn, can lessen their turnover intent. This study also intends to know whether or not motivation strategies have any direct correlation to turnover intention. Ensuring employees’ loyalty is vital especially because millennials have the tendency to hop from one job to another. Furthermore, one-third of the Philippine workforce population is already millennials, and soon, they will compose more than half of it. A total of 350 respondents with ages 20 to 37 years old from the banking industry at the National Capital Region in the Philippines were requested to answer a 5-part questionnaire consisting of 55 questions with the following variables of "Motivation Strategies", "Employee Motivation", "Employee Engagement" and "Turnover Intention". Data gathered from the survey was processed using SPSS 22 and AMOS 24. The results from the Structural Equation Model (SEM) confirmed the study’s hypothesis that Motivation Strategies have an effect on Turnover Intention. Evidently, results also showed that Employee Motivation and Employee Engagement did not show any effect on the Turnover Intention of Millennial employees. Further studies may be conducted to explain why Employee Motivation and Engagement does not have a direct nor mediating effect on the turnover intent of millennials in the banking industry.

The objective of the study is to describe the syllable structures exhibited by Filipino-dominant speaking four-year-old children. A total of nineteen audio-recorded connected speech samples were transcribed, segmented, and analyzed to describe the syllable structures through identifying the parts of a syllable, the number of syllables in a word, and the combination of the different syllable structures exhibited by the participants. Descriptive and cross-sectional secondary data analysis was used to describe the different syllable structures. The most frequently occurring syllable structure is CV followed by CVC. Consonants Inf and/?/are the most frequently occurring onset and coda, and vowel /al for the nucleus. Furthermore, the most frequently occurring number of syllables are one-syllable and two-syllable words with syllable structure combinations CVC, CV.CV,CV.CVC and CV. As for diphthongs and clusters, the occurrence was less frequent (less than 5% of the total sample) as Filipino words primarily do not contain these. The increase in number of syllables resulted from the reduplication of the verbs and affixes. Overall, the results of the current study may serve as basis for word structure, monitoring, and regulating the expected skills and development of Filipino children.

Published: June 2020

For a number of decades, healthcare professions and organizations have utilized the recording of vital signs as a means to evaluate the physiological status of an individual. In this study, an extended framework in the analysis of the dynamics of human vital signs of individuals performing strenuous activities specifically jogging on overweight and underweight individuals with the use of deterministic approach of chaos theory in the human vital signs is presented. With the use of the Largest Lyapunov Exponent test, it was recognized in a previous study that the chaotic properties of vital signs during physical exercises of individuals with normal body mass index is present. To further examine, this study focused on the health risk of overweight and underweight individuals in their jogging sessions. The Largest Lyapunov Exponent test was used to measure the risk according to the degree of chaos in each vital sign (blood pressure, respiration rate & heart rate). The Body Mass Index are correlated to the occurrence of chaotic patterns to evaluate whether being overweight or underweight can be considered as a risk factor. This research aims to present a guideline in the reduction of risks that is associated with the irregularities in jogging patterns of overweight and underweight individuals.
Molecular Docking of Ipalbidine into Human Cyclooxygenase-2 Protein Crystal Structures
Authors: Egwolf Bernhard , Espiritu Josh David M.
Published: June 2020

Cyclooxygenase-2 (COX-2) is an enzyme responsible for the production of the prostaglandins, lipid molecules related to pain, inflammation, etc. Ipalbidine is a compound extracted from the crushed seeds isolated from Ipomea Alba L. (Moon Flower), which is a herbaceous vine usually found in tropical and subtropical areas in the world. The strength of the binding between a biomolecule and a ligand (drug or inhibitor) can be expressed in terms of binding affinity. When performing molecular docking, the binding affinity of a ligand bound to a receptor, in this case Ipalbidine bound to COX-2 structures, can be acquired. The seven currently available human COX-2 structures from the Protein Data Bank have been downloaded and prepared for molecular docking. Four programs have been used for the study: Autodock Tools, Autodock Vina, Visual Molecular Dynamics, and Chimera. After preparation, the binding affinities of the original bound ligands within the respective COX-2 structures were calculated. Next, the binding affinities of Ipalbidine and the seven crystal structures of COX-2 were acquired using molecular docking. The results show that Ipalbidine has a slightly lower binding affinity to the COX-2 structures compared to the original bound ligands, except for one. However, the rigid COX-2 crystal structures used in this study are optimized to accommodate the original bound ligands, not lpalbidine. In other words, the docking results for lpalbidine are expected to systematically underestimate binding affinities.
Molecular docking of modified ipalbidine ligands into human cyclooxygenase-2 protein crystal structures

Published: June 2020

With many negative side-effects of nonsteroidal anti-inflammatory drugs such as gastrointestinal problems and the withdrawal of most selective COX-2 inhibitors from the market due to its increased risk of heart disease, there is a demand for an alternative analgesic (pain reliever) with less adverse side-effects. Nowadays, molecular docking is a major computational tool for drug development and drug design. This study focuses on the modification of potential analgesic ipalbidine in order to optimize its binding affinity to seven human COX-2 structures using Autodock Vina as a docking tool. Two different modified ligands were successfully enclosed in the COX-2 protein structure and were able to bind to the binding site. Based on the obtained binding affinities, it was found that by increasing the amount of hydrogen atoms on the ligand by converting the carbon double bond into a single bond, the binding affinity was reduced due to the hydrophobicity of the binding site liners. The second change was ipalbidine with inverted chirality. Inverted chirality showed higher binding affinities across the board, implying improved efficacy and bond strength. However, a change in the chirality of a drug may alter the selectivity or effect of the drug as a whole, and therefore clinical trials may be required to identify possible side-effects that may arise.

Authors: Idris N N , Mustaffa Z , Ismil N N A
Published: June 2020

Carbon steel pipeline is known as the safest method to transfer a large volume of oil and gas from sources to the consumers. Carbon steel has higher tendency to fail after long time because of major hazard such as corrosion. Corrosion develops at both sides of pipeline wall; internally and externally thus the strength and integrity are affected caused by such metal deterioration. This paper emphasizes on defects interaction between external and internal walls in the radial orientation towards failure burst pressure. To date, there are no standards, codes or guidelines on radial corrosion defect to explain such behaviour. Seven types of corrosion arrangement retrieved from literature were modelled in finite element software for a pipeline in the grade API 5L X42. Von Mises distribution curve was plotted to determine the pipeline pressure limit at different corrosion arrangement. The maximum radial interaction with the lowest failure pressure was determined from the values obtained.

The results showed that all ultrasonic treated bags had shorter time for mycelium to fill-up the mushroom bags as compared to control. Ultrasonic treated bags was observed could promote and activate the pinhead emergence and fruiting bodies formation. Besides, all ultrasonic treated bags also showed higher yield and better quality in terms of the largest pileus diameter of mushrooms as compared to control. For the color of mushrooms, there was no significant different (P>0.05) observed in L* values. However, treatment of 1.5 minutes had the highest a* (redness) and b* (yellowness) values. Different durations of ultrasonic treatment did not showed any significant different in texture and moisture content of mushrooms. In summary, 1.5 minutes was the best treatment duration as it took the shortest time for different growth stages with the greatest yield of mushrooms.

This paper discusses about the charging profile of a lead acid battery used in electrical scooter. Lead acid battery is a robust and widely used in small electric vehicle because of its price tag. It can be considered to be one of the mature battery in the market thus the charger too. Each lead acid battery from different manufacturer possess different characteristic hence not all charger is suitable for any lead acid battery. The experiment was conducted to determine the charging profile of a 12 V cells lead acid battery connected in series to make 48V battery source. The charging current and voltage were logged and analysed for 3 charge rate. The measurement design of experiment is presented in detail as well. The experiment was repeated for at least four times. As the charging rate increase, the time taken for the charging process to complete became shorter. Nevertheless, we saw that the full battery capacity reduced at faster rate for a higher charger rate. The charging profile of the battery are also validated by the single-cell 12V battery to prove the series and parallel charging significance.

Porous silicon (PS) is a candidate for silicon-based optoelectronic applications. This paper presents the effect of etching time on the properties of PS deposited by a nano-thin film of a silver layer (10 nm Ag/PS) using radio frequency (RF)-sputtering technique at room temperature (RT). The PS was prepared by electrochemical etching (ECE) method for n-type (111) Si in an electrolyte solution containing hydrofluoric acid (HF) and ethanol (C2H6O) at a volume ratio of 1:4 with a direct current of 10 mA for different etching duration (30, 45, and 60 min). Structural, surface, and optical characterizations of the samples were carried out by using field emission scanning electron microscopy (FESEM), energy dispersive X-rays (EDX), X-ray diffraction (XRD), UV–Vis spectrophotometer, and photoluminescence (PL) spectroscopy. The results show that the sample prepared for 30 min demonstrated enhancement in the PL and reflectivity spectra compared to other samples which indicate a higher etching rate and a thinner wall between the pores on the surface over a larger exposed area was obtained.
