Impact of Online Video Advertisement on Impulsive Buying Tendency with the Mediating Effect of Attitudes (Evidence from University Students in Sri Lanka)

Purpose: TikTok is a growing video-sharing application that allows users to make and share short videos on any topic. At present, young consumer’s impulsive decisions have been increased steadily, due to higher exposure to TikTok on online context. Thus, this research was carried out to examine the factors impacting on impulsive buying tendency of young consumers with a particular focus on attitudes toward online advertisements. Design/methodology/approach: Through a comprehensive survey conducted among 200 undergraduates at University of Ruhuna, data was collected based on a convenient sampling technique. Further, the collected data was analyzed using Smart PLS 4 software. Findings: The findings indicated that informativeness, personalization, and credibility of online video advertisements positively affect attitudes toward online video ads. Additionally, the mediating effect was proved revealing that young consumers make impulsive purchasing decisions based on the attitude formation through informativeness, personalization, and credibility. Originality: Although, the application of Tik Tok is important as a marketing tool, research on the TikTok platform is still scarce and inadequately documented. Implications: The study provides practical advice for marketers and brand managers to focus on improving consumers’ perceptions through the video ad’s informativeness, entertainment, personalization, and credibility to encourage consumers to purchase impulsively.

Comparing the effectiveness of oral montelukast versus cetirizine in the management of allergic rhino-conjunctivitis and its effect on quality of life among children: A randomized, double-blind clinical trial

Background: Allergic rhino-conjunctivitis (AR) is a common disorder in children, which causes significant morbidity and impact on learning and day-to-day activities. Objectives: To compare effectiveness of montelukast versus cetirizine in AR and its effect on the quality of life (QoL) among children aged 6-12 years, attending Asthma Clinic, Faculty of Medicine, University of Ruhuna, Sri Lanka. Method: This was a randomized, double-blind, parallel-group trial; 'Group A' was given montelukast with a cetirizine dummy; 'Group B' was given cetirizine with a montelukast dummy. Primary endpoint was to compare improvement of nasal, eye and night symptom scores. Secondary endpoint was to compare the QoL between the groups. Total symptoms were assessed at baseline, one month, two months and three months. Results: There were 176 children (62.5% boys) with a mean age of 8.82 ± 1.79 years. Fifteen children were lost to follow-up, 7 from the montelukast and 8 from the cetirizine group. There was a significant reduction in all symptoms (p<0.05) every month in both treatment groups. Whilst montelukast group had more improved day and night symptom scores than cetirizine group, statistically significant improvement was seen only in the 3rd month (t-4.10 p <0.001). Mean QoL score showed no significant difference between the two groups at onset (montelukast 9.01±9.4 and cetirizine 15.9 ± 10.4; t-0.369; p=0.712). Both groups showed a statistically significant improvement in all domains of QoL by completion of treatment (p<0.05). Upon completion, the montelukast group showed a significantly better QoL than the cetirizine group. Conclusions: Both cetirizine and montelukast showed remarkable improvement in the symptoms and better QoL in children. Study outcomes in all clinical domains and QoL were more significantly improved in montelukast group than in cetirizine group when treatment was continued for 3 months.

Variation in plant morphology and leaf essential oil composition of a representative <em>Cinnamomum verum</em> collection from Sri Lanka

Sri Lankan cinnamon germplasm is an underexploited genetic resource of high breeding potential. A representative collection of a cultivated cinnamon germplasm with 48 accessions, is established at the University of Ruhuna, Sri Lanka. From that collection, 40 three-year-old vegetative-propagated accessions, were used in this study to study the variations in plant morphology and leaf oil composition. Flush colour was determined as four main categories of pink, red, brown, and green in all 48 accessions. Leaf length, leaf width, leaf length to width ratio and petiole length varied from 7.9 to 14.5 cm, 3.8 to 7.3 cm, 1.8 to 3.07 cm, and 1 to 2.2 cm, respectively, in the selected 40 accessions. Both the good fragrant aroma category of bark fragrance and the sweet pungent category of bark taste were recorded in 21 of the 40 accessions. Twenty (20) accessions from above collection were selected for leaf oil analysis. Gas chromatography-mass spectrometry (GC-MS) of leaf oil revealed the presence of 146 chemical compounds. Eugenol was the major compound of 17 accessions (52.2% to 79.5%). Two accessions with zero eugenol contained 86.8% and 91.9% of benzyl benzoate (BB), in contrast to that of 0%-0.65% from other accessions. One accession produced 16.6% eugenol and 22.3% BB. A green flush colour associated with a higher BB percentage suggested a potential morphological marker for BB. The PCA for 20 accessions explained 88.11% of total variance. The cinnamon accessions with high BB, KA11 and GB17, were clustered together, and HB12 was isolated on a different cluster. Positive correlations were detected between linalool and β-caryophyllene (0.649), linalool and BB (0.770) (p < 0.01), and negative correlations between eugenol and linalool (-0.630) and eugenol and BB (-0.886) (p <0.01).

Knowledge in identifying venomous snakes and first aid methods of snakebites among nursing students: A cross-sectional study.

Snakebites are a dangerous and significant medical emergency that occurs worldwide. The World Health Organization has recommended that teaching and training in the prevention and management of snakebites be included in the curriculum of nursing schools and other educational activities. Identification of venomous snakes and first aid would be more critical in the prevention of occupational danger worldwide. This study aims to assess the knowledge in identifying venomous snakes, snakebites, and first aid methods of snakebites among nursing students in the Southern Province of Sri Lanka. A descriptive, cross-sectional study was performed among 425 nursing students who were studying in different educational settings: undergraduates at the University of Ruhuna, and nursing students in the three schools of nursing in Galle, Matara, and Hambantota. Data were gathered by incorporating a pre-tested self-administered questionnaire after obtaining institutional permission. The total score of whole knowledge ranged from 0 to 34 for the identification of venomous snakes. Data collection was performed after obtaining ethical clearance from the Ethics Review Committee, Faculty of Allied Health Sciences, University of Ruhuna, Sri Lanka. Most of the students (82.6%) were in the 24-26 age category and the majority were females. Most of the sample (64.7%) had low knowledge of identifying venomous snakes. A higher percentage of students (57.4%) had a sufficient level of knowledge about first aid methods associated with snakebites and 169 participants (39.8%) had a high level of knowledge regarding first aid methods. Further, a significant impact on students' knowledge and knowledge of first aid methods was reported. The overall knowledge of identifying venomous snakes among the nursing students was inadequate. However, the knowledge about the first aid methods was at a moderate level. Strategies are needed to improve knowledge in identifying venomous snakes and first aid methods of snakebites amongst nursing students in both educational settings.

A comparison of environmental performance of electronic and bound-thesis using life cycle assessment

Dematerialization through information technology aids in advancing environmental sustainability. Replacing a bound thesis with an e-thesis for a university dissertation will be a complementary paradigm shift for higher environmental performance. Hence, the study intended to determine and compare the environmental performance parameters of conventional paper-based bound-thesis and e-thesis. Moreover, the study aimed to identify the activities causing higher environmental burdens during the production of bound and e-thesis. Open LCA 1.11 was employed for a conventional bound thesis with its e-version submitted by the undergraduates of the Faculty of Agriculture, University of Ruhuna, Sri Lanka. The study utilized U.S. EPA life-cycle inventory data. The analysis demonstrated that the overall global warming potential of a 40-page hard cover thesis was 4,839,000.00 kg CO2-eq to which paper and cover import and paper manufacturing stages contributed more than 99% (4,830,000.0 kg CO2-eq). In comparison, a 0.084 MB soft copy of an e-thesis reported a negligible (0.09936 kg CO2-eq) global warming potential value. Ozone formation-human health, ozone formation-terrestrial ecosystems, terrestrial acidification, fine particulate matter formation, and marine eutrophication potential were 265,584.31 kg NOx eq, 265,583.21 kg NOx eq, 177,451.5 kg SO2 eq, 52,948 kg PM2.5 eq, and 29,041.0 kg N-eq for bound thesis production system. Except for the stratospheric ozone depletion impact and water consumption, environmental performance indicators of e-thesis were superior to the conventional-bound thesis. The study recommends the preparation of e-thesis as an environmentally sound approach. Switching to renewables, extended lifespan, and material recycling of devices at the end of use, sustainable forestry practices, process optimization, and cleaner production technologies can further enhance the environmental performance of e-thesis.

Effect of the Presence of Pus Cells in Seminal Fluid Samples on Sperm Motility and Morphology in a Group of Males Attended Subfertility Clinics in Galle District, Sri Lanka

Background: The quality of seminal fluid is one of the main determinants of male fertility. The quality of seminal fluid is determined by several parameters such as volume, sperm concentration, percentage of normal morphology, motility, viability, progressivity, etc. The objective of the study was to assess the effects of the presence of pus cells in seminal fluid samples on normal morphology and motility. Methods: A cross-sectional study was conducted among a sample of 107 men who attended subfertility clinics in Galle district, Sri Lanka. Consecutive (convenience) sampling method was used. After obtaining the informed consent, semen samples were collected. Pus cell count, sperm motility and normal morphology were evaluated based on the WHO guidelines (2010). Ethical approval was obtained from the Ethics Review Committee, Faculty of Allied Health Sciences, University of Ruhuna. Results: The majority of samples had pus cell count less than 5 per high power field (n=75, 70.1%). Only 32 (29.9%) had a pus cell count of 5 or above per high power field (/HPF). 32 samples (42.7%) out of 75 samples with pus cell count <5 (/HPF) had a percentage normal morphology of more than 30%, while only 3 samples (9.4%) with pus cell count ≥5 (/HPF) had a percentage normal morphology of more than 30%. The mean and standard deviation (SD) of normal morphology were 26.88% and 8.69% for samples with pus cell count <5 (/HPF) while 21.39% and 7.00% for samples with pus cell count ≥5 (/HPF). Z value was 3.124 and the level of significance was 0.05. Therefore, the finding was highly significant (p= 0.002). 32 samples (42.7%) out of 75 samples with pus cells <5 (/HPF) had normal motility (≥50%). However, only 6 (19%) of 32 samples with pus cells ≥5 (/HPF) had normal motility (≥50%). The mean and standard deviation (SD) of normal motility were 46.32% and 11.30% for samples with pus cell count <5 (/HPF) while the mean and standard deviation (SD) of normal motility were 41.25% and 10.37% for samples with pus cell count ≥5 (/HPF). Z value was 3.124 and the level of significance was 0.05. Therefore the finding was highly significant (p = 0.032). Conclusions: The obtained results demonstrated that the pus cell count can be a factor inversely associated with sperm morphology and motility.

Career Perception on Banking Industry among Management Undergraduates

Career perception especially among management graduates is a vital phenomenon that is under exploration among academics. However, no previous research has been done on exploring this phenomenon in Sri Lankan context. Thus, addressing the knowledge gap in the literature, the main purpose of this study is to identify the significant factors determining career perception on banking industry among state university management undergraduates in Sri Lanka. Based on the extant literature four independent variables namely social status, physical working conditions, financial benefits, career growth were identified to address the research question of the study. The sample was derived from 152 third and final year management students from university of Ruhuna. Self-administered questionnaires were used to collect the necessary data. Multiple regression analysis was used to test the hypotheses. The study found that social status, physical working conditions, and financial benefits are significant factors explain the career perception on banking industry among respondents. These findings particularly would be beneficial to undergraduates and career counseling institutions as well as for the society at large.

Psychological disturbances encountered by selected undergraduates studying at the University of Ruhuna, Sri Lanka during the Covid-19 pandemic: a cross-sectional study

University undergraduates are increasingly recognized as a vulnerable population with a higher level of psychological disturbances. During the Covid-19 pandemic, universities closed all over the world, resulting in the psychological well-being of this population being severely affected across the globe. This study examined the prevalence of stress, anxiety, and depressive symptoms encountered by undergraduates of the selected five faculties at the University of Ruhuna in Southern Sri Lanka due to the Covid-19 pandemic, its associated factors, and the correlations between stress, anxiety, and depressive symptoms. An online, cross-sectional, descriptive study was conducted among undergraduates using pre-tested, self-administered questionnaires from the randomly selected five faculties: Allied Health Sciences, Engineering, Humanities and Social Sciences, Management and Finance, and Medicine. Undergraduates were invited to complete the Google Form. Socio-demographic details and a 21-item Depression, Anxiety, and Stress Scale (21-DASS) were used for data collection. Stress, anxiety, and depressive symptoms were evaluated using a Sinhala version of the 21-DASS scale. Ethical permission was granted by the Ethics Review Committee of the Faculty of Allied Health Sciences, University of Ruhuna. Among the 359 undergraduates, the majority were represented by females (62.1%). The mean age of the sample was 23.67 years (SD ± 1.6). Stress, anxiety, and depressive symptoms were found to be prevalent in 53.7%, 41.8%, and 63.8% of undergraduates respectively. Younger and female undergraduates had more impact on psychological issues than their counterparts. It revealed a significant positive correlation between anxiety and depressive symptoms (r = 0.646, p < .001), anxiety and stress (r = 0.868, p < .001), and stress and anxiety (r = 0.786, p < .001). Most undergraduates experienced considerable levels of stress, anxiety, and depressive symptoms during the Covid-19 as increasing stress, anxiety, or depressive symptoms, tend to increase all types of psychological disturbances. The development of mental health among undergraduates is essential and needs innovative strategies to improve the psychological well-being of undergraduates. The initiation of a stress management programme and expanded available counseling services are also important. Further studies are needed to be conducted on the extended topic of how the Covid-19 era is affecting the psychological well-being of undergraduates from different universities (state/non-state), locations, and different study departments.

Knowledge regarding Human Papilloma Virus, Related Diseases and Preventive Measures Among Female Undergraduates of a Selected University in Sri Lanka

Background and objective: Increasing awareness of human papilloma virus (HPV), its related diseases and preventive measures among young female population play a major role in reducing the associated health risk This cross-sectional study was aimed to assess knowledge and associated factors regarding human papilloma virus, related diseases and preventive measures among female undergraduates at the University of Ruhuna (UoR), Sri Lanka. Methods: Female undergraduates (n=400) from five Faculties (Medicine, Allied Health Sciences, Engineering, Management and Finance and Humanities and Social Sciences) of UoR were included in the study through one-stage cluster sampling. The data were collected using a pre-tested, self-administered questionnaire with 45 statements to assess knowledge. The knowledge score was calculated by assigning one point to a ‘true’ answer and zero point to a ‘false’ and ‘no idea’ answers. The level of knowledge was divided in to three categories as Poor (0 – 15), Average (16 – 30) and Good (31– 45). Descriptive statistics and Chi square/Fishers’ exact test were used for analysis with SPSS Version 25. Results: The mean±SD knowledge score was 18.49±11.97. Only 38.3% (n=153) of undergraduates had good knowledge while 31.8% (n=127) had average and 30% (n=153) had poor knowledge. Level of knowledge was associated with age (p&lt;0.001), faculty (p&lt;0.001) and academic year (p&lt;0.001). Comparatively high proportion of female undergraduates aged 24-30 years, studying in Faculty of Medicine and Allied Health Sciences in their final academic years had good level of knowledge compared to the counterparts. Conclusions: Inadequate knowledge regarding HPV, related disease and preventive measures was seen among female undergraduates of UoR. Level of knowledge was associated with the age, faculty of studying and academic year of the female undergraduates. Educational programmes on HPV and cervical cancers could be promoted among female undergraduates to popularize the related awareness.

Effect of Plant Growth Regulators on Growth of Wallapatta (&lt;em&gt;Gyrinops walla&lt;/em&gt; Gaertn.) Seedlings

Gyrinops walla Gaertn belongs to family Thymelaeaceae is the only agarwood producing plant species naturally found in Sri Lanka. With the recognition of its ability to produce highly valuable agarwood, the species is under threat due to illegal harvesting from the natural habitats. Commercial cultivation of the species is yet to be started due to lack of information on relevant cultural practices. The present study was therefore aimed at evaluating the effect of Plant Growth Regulators (PGRs) on growth of G. walla seedlings. The experiment was conducted at the Faculty of Agriculture, University of Ruhuna from August 2019 to May 2020. Different combinations of Gibberellic acid (GA3) and 6-Benzylaminopurine (6-BAP) were tested as foliar applications in an experiment arranged in Randomized Complete Block Design with 3 replicates. Stem height, stem diameter, fresh and dry weight of shoot and root were measured as growth parameters. The combination treatment of GA3 and 6-BAP at 50 ppm and 100 ppm respectively resulted in significantly (p&lt;0.05) higher stem height, stem diameter, leaf area, fresh and dry weight of shoots and roots compared to those of the control which did not receive any growth regulator. Furthermore the treatment significantly (p&lt;0.05) increased the shoot: root ratio also compared to the control. Based on the results, foliar application of GA3 (50 ppm) along with 6-BAP (100 ppm) can be recommended to enhance the seedling growth of G. walla.

Growth Performances of Cocoa (&lt;em&gt;Theobroma Cacao&lt;/em&gt;) Varieties under Mature Oil Palm with Palm Oil Mill Effluent as Growing Media

Oil palm (Elaeis guineensis) is a leading edible oil-producing plant established in tropical countries which cause many negative impacts. Poor productivity of monoculture plantations and land and aquatic pollution caused by haphazard release of Palm Oil Mill Effluent (POME) are critical concerns. As a remedy, oil palm can be intercropped with cocoa by using POME as a potting media. In this study, we evaluated the growth of two different cocoa varieties with POME as the potting media under 20 years old oil palm shade. Two cocoa varieties (SCA6 x ICS6, and NA32 x ICS1) and three potting media (topsoil only, 40% topsoil with 60% POME, and 60% topsoil with 40% POME) were factorially combined in a randomized complete block design with three replicates under 40% shade, Faculty of Agriculture, University of Ruhuna. Growth parameters of the cocoa seedlings such as plant height, number of leaves, chlorophyll value, stem girth, root and shoot dry weights, root length, number of lateral roots per plant were measured using destructive and non-destructive sampling methods. The potting media consist of 40% topsoil with 60% POME showed significantly the highest plant height, number of leaves, chlorophyll value, stem girth, fresh and dry weight of shoot and roots and length of roots. Hence, potting media with 40% topsoil with 60% POME was recognized as the best potting media for the growth and development of cocoa seedlings of both varieties. Growth of cocoa seedling was well compatible under oil palm shade at full light condition with the use of POME as the potting media.

Lessons in personal change; how a book helped me to be an effective leader

In the aftermath of the December 2004 Asian tsunami, as the newly elected Dean of the Faculty of Medicine, University of Ruhuna, I had to face many challenges. A self-help book, titled “The 7-Habits of Highly Effective People” authored by Dr. Stephen R Covey, had a profound positive effect on my life, empowered me and helped to overcome these challenges. The unique feature of this book is that it advises on character building rather than achieving success as in most self-help books. The 7-habits that are recommended by Dr. Covey are: be proactive; begin with the end in mind; put first things first; think win-win; seek first to understand, and then to be understood; synergize; sharpen the saw. Each habit is discussed, followed by an example of project/activities for which I gave initiative and leadership.
