Advances in Journalism and Communication (AJC) , 2018, DOI: 10.4236/ajc.2018.62006
Abstract: In this modern digitalized world, almost everyone is attached with internet. So there is an opportunity for the advertisers to use the social apps/internet for the purpose of advertising. This study was conducted to check the impact of social media advertising on customers’ purchase intention while considering the customers’ motivation and customers’ perception as mediating variables. This is a qualitative study based on the interpretivism philosophy which is conducted on university students in China. The population for this research was the entire students of the university and the data were collected through interviews from 10 respondents. The respondents were the students of different departments of the university owning the smart phones and using Facebook and Instagram. Framework analysis approach was used to see the common responses of students regarding outcomes of social media advertising. The results have indicated that advertising on social media increases customers’ motivation and improves perception of the company for viewers which ultimately enhances customers’ purchase intention.

Abstract: Background: Chronic Heart Failure is a complex clinical conditions affecting patients’ Quality of Life (QoL) globally. Objective: The aim of the study was to identify the factors influencing the quality of life of the chronic heart failure patients. Methods: A descriptive exploratory study was carried out by face-to-face interview with structured standard questionnaire. One hundred and forty two hospitalized chronic heart failure patients were conveniently recruited from National Institute of Cardiovascular Disease and Hospital, Sher-e-Bangla Nagar, Dhaka, Bangladesh. Data were collected from January to February, 2019. Quality of life related factors were identified using Patients’ General Characteristics Questionnaire. QOL of chronic heart failure patients was measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and the World Health Organization’s Quality of Life Instrument-Short Version (WHOQOL-BREF). Descriptive statistic was used to describe the samples’ characteristics. Association between Socio-demographic characteristics and QOL of chronic heart failure patients was measured using t-test and one way of ANOVA. Relationship between continuous variables was measured by Pearson correlation test. Results: Findings reveal that mean of the total chronic heart failure related quality of life was 94.16 (SD = 3.20) out of maximum of 105. This high score indicates worsen chronic heart failure patients’ quality of life. The mean score of general quality of life of chronic heart failure patients was calculated as 41.05 (SD = 5.109) out of maximum of 130 which indicates low level of general quality of life of chronic heart failure patients. There is a significant positive correlation found between disease related quality of life and general quality of life of chronic heart failure patients. Dimensions of physical (r = 0.248, p = 0.000), mental (r = −0.180, p < 0.001) and total (r = −0.141, p < 0.001) of MLHFQ were significantly correlated with psychological dimension of WHOQOL-BREF except total two dimensions of its. Gender, marital status, education, income, smoking, residence and BMI were identified as factors having an effect on QOL of Chronic Heart Failure patients. Conclusion: Further intervention study is necessary to improve the quality of life of chronic heart failure patients.

Abstract: The current study evaluated the antioxidant, α-amylase inhibitory and anti-Staphylococcus aureus activities of the fruiting bodies of Ganoderma lucidum. Methanolic extract of G. lucidum (MEGL) was investigated for its in vitro antioxidant activity using 1,1-diphenyl 2-picrylhydrazyl (DPPH) assay and EC50 value was determined. α-Amylase inhibitory and anti-S. aureus activities were carried out by conventional methods. The mushroom extract showed maximum free radical scavenging activity at a dose of 500 μg/mL with EC50 value of 22.1399 μg/mL. EC50 value for the inhibition of α-amylase activity was found 22.6011 μg/mL. G. lucidum extracts exhibited a concentration-dependent Anti-S. aureus activity. The vast differences of this inhibition between lower and higher doses were assessed significantly (p < 0.05). This study shows that the fruiting body of G.

Abstract: The effects of conservation agriculture (CA) practices on soil properties along with crop yields of rice-based triple cropping systems have not been adequately assessed in Bangladesh. An experiment was conducted at Bangladesh Agricultural Research Institute, Gazipur, Bangladesh from 2009 to 2012 to assess the effects of tillage practices and crop residue retention on soil physical properties, soil organic carbon (SOC) and crop yields in a wheat-mungbean-rice system. Treatments consisted of three tillage practices (MT: minimum tillage; CT: conventional tillage and DT: deep tillage) and eight levels of crop residue management (S0—no residues retention, Sr—retention of 30 cm rice straw, Sm—whole mungbean stover retention, SW—30 cm wheat straw retention, Smr—whole mungbean stover & 30 cm rice straw retention, Srw—30 cm rice & wheat straw retention, Smw—whole mungbean stover & 30 cm wheat straw retention and Swrm—30 cm wheat and rice straw along with whole mungbean stover retention) were applied in split plot design with three replications. Bulk density (BD) and porosity responded positively to MT and increased residue retention of all crops (p > 0.05). Minimum tillage and Swrm also significantly accumulated SOC (p < 0.05; 0.38% higher than DT with no residue retention) and retained soil moisture (p < 0.05). Minimum tillage practice performed better in upland crops (p < 0.05; wheat & mungbean yields) and CT outperformed MT in wetland rice crop (p < 0.05). The grain and straw yields of wheat and rice were also influenced by previous crop residue retentions (p < 0.05). The results, therefore, suggested that increased residue retention with minimum tillage practices improved soil properties and yield of upland crops but with deeper tillage practices consistently maintained wetland rice production.

Journal of Electronics Cooling and Thermal Control (JECTC) , 2016, DOI: 10.4236/jectc.2016.61002
Abstract: Electromigration is a main challenge in the pursuit of power electronics, because physical limit to increase current density in power electronics is electromigration (EM), whereas much higher electrical current and voltage are required for power electronics packaging. So the effect of EM is an important issue in applications where high current densities are used, such as in microelectronics and related structures (e.g., Power ICs). Since the structure size of integrated circuits (ICs) decreases and the practical significance of this effect increases, the result is EM failure. On the other hand, in the next generation power electronics technology electrical current density is expected to exceed 107 A/cm2 which is another challenge. This review work has been carried out to identify the mechanism of EM damage in power electronics (e.g., pure metallization and solder joints) and also how to control this kind of damage.

Abstract: The major purposes of the study were to determine the extent of the problem faced by the farmers in bean cultivation and to explore the relationships between bean farmers’ selected characteristics with their problem faced. The study was conducted in four villages of two unions under Atghoria upazilla of Pabna District. Data were collected from a random sample of 106 bean farmers by using an interview schedule during 15 Dec, 2017 to 15 Jan, 2018. The highest proportion (71.70 percent) of the farmers faced medium overall problem in bean production, while 16.04 percent faced high and 12.26 percent faced low problem. Problem faced in non-availability of pesticides ranked 1st and this was followed by non-availability of fertilizers, lack of capital so on and least one lack of irrigation in bean cultivation ranked 28th. Correlation analysis indicated that education, training exposure, organizational participation, extension media contact and farmers’ knowledge had significant negative relationship with their problem faced. Age had significant positive relationship with their problem faced while family members, farm size, annual family income, bean cultivation area, and credit received by the farmers had no significant relationship with their problem faced. Overwhelming (87.74) majority of bean farmers faced medium to high problems therefore, it may be said that problem faced by the farmers in bean cultivation is a serious issue to be addressed to maximize bean production.

Journal of Information Security (JIS) , 2018, DOI: 10.4236/jis.2018.93015
Abstract: Handwritten signature and character recognition has become challenging research topic due to its numerous applications. In this paper, we proposed a system that has three sub-systems. The three subsystems focus on offline recognition of handwritten English alphabetic characters (uppercase and lowercase), numeric characters (0 - 9) and individual signatures respectively. The system includes several stages like image preprocessing, the post-processing, the segmentation, the detection of the required amount of the character and signature, feature extraction and finally Neural Network recognition. At first, the scanned image is filtered after conversion of the scanned image into a gray image. Then image cropping method is applied to detect the signature. Then an accurate recognition is ensured by post-processing the cropped images. MATLAB has been used to design the system. The subsystems are then tested for several samples and the results are found satisfactory at about 97% success rate. The quality of the image plays a vital role as the images of poor or mediocre quality may lead to unsuccessful recognition and verification.

Abstract: This study was carried out to investigate the drug resistance pattern of Salmonella spp. from diarrheal patients of under 5 years of age. Collected stool samples from the hospitalized diarrheal patients were analyzed for the presence of Salmonella spp. Among 350 stool samples from diarrheal patients, 15 (4%) were positive for the Salmonella spp. Antibiotic susceptibility test of the identified Salmonella spp. was performed according to Kirby-Bauer disc diffusion method. Eight commonly used antibiotics including azithromycin (15 μg), chloramphenicol (30 μg), Sulphamethaxole-trimethoprim (25 μg), metronidazole (50 μg), tetracycline (30 μg), doxycycline (30 μg), erythromycin (15 μg) and ciprofloxacin (5 μg) used to determine drug resistance pattern of the identified Salmonella spp. Majority of the isolates were multidrug resistant showed resistance against more than three drugs. 73% of Salmonella spp. was resistant to 2-4 drugs and 20% showed resistance to more than 5 drugs. We found that 100% Salmonella showed resistance to metronidazole and 87% were resistant to erythromycin. 7% isolates were resistant to chloramphenicol and doxycycline and 20% were resistant to ciprofloxacin. Antibiotic resistance is a serious public health problem worldwide and a leading cause of mortality and morbidity. This kind of situation, leads to great socioeconomic losses from the perspective of the patient, the hospital, and the whole society. To get rid form the drug resistance problem unnecessary, over and misuse of antibiotics should immediately prohibited and policy of judicious use of antibiotics should be strengthened. Asian J. Med.

Abstract: Intensive Care Unit (ICU) is an advanced service available in hospitals for potentially recoverable patients who have acute life-threatening single or multiple organ system failure due to disease or injury. The aim of this study is to explore the characteristics of adult ICU patients at a university Hospital in Bangladesh. A descriptive study design was carried out to conduct this study. Data were collected from 112 conveniently selected ICU patients, by observing their medical documents and interviewing patients’ attendants. The findings of this study showed that the mean age of the recruited ICU patients was 55.82 ± 19.185 years. Most of the participants were male 63.4%, Muslims 89.3%, and married 84.8%. The most common co-morbidities were DM 49.1%, HTN 47.3% and CKD 33.0%. Among the ICU patient, 50.9% was unconscious and 60.7% of patients were in mechanical ventilation. The health related characteristics such as systolic blood pressure, diastolic blood pressure, serum electrolytes, arterial blood gas analysis, etc were at the normal limit and the most common ICU related complication was septicemia 15.2%, and aspiration pneumonia 18.8%. The average length of stay in ICU was 7.73 ± 8.782 days. The outcome characteristics of ICU patients were death at 49.1% and live was 50.9%. ICU is an important component of tertiary care hospital that admits patients with severe and life-threatening conditions. This study findings show that the elderly population with DM, HTN and CKD are frequently admitted in the ICU and have been suffering from multiple ICU related complications and challenges.
