Cross-border shopping represents an important concept for online cross-border e-commerce in 2020. We took place in mainland China with the covid-19 in 2019, which led to a large number of consumers buying masks globally. Many consumers will go to other countries to buy medical products such as masks and alcohol through online cross-border means. Consumers' purchase cognition, impulse purchase and illness information all lead to consumers' purchase intention and satisfaction. The public medical event caused consumers to buy masks, alcohol and other medical products in large quantities to prevent the epidemic. The results of this study show that consumers' expected purchase of goods, mainly due to the shortage of masks, indirectly leads to consumers' expected purchase of goods on online foreign e-commerce platforms. We found that consumers' expectations and perceptions lead to impulsive online purchases and ultimately to an understanding of consumer satisfaction.

Tooth impaction occurs when a tooth is prevented from erupting into the oral cavity which is their functional position within an expected time. The mandibular third molars are the most frequently impacted tooth in the oral cavity. Some studies have reported a higher frequency in females than males. A search through the literature shows that no study has been done to ascertain the socioeconomic status of patients presenting with third molar impaction in Nigeria. This study is therefore aimed at determining the pattern of presentation and socioeconomic distribution of patients presenting at the Lagos state University Teaching Hospital for extraction of impacted third molar. 337 patients with impacted third molar who had indication for extraction and had met the inclusion criteria were included in the study after obtaining a signed consent. The positions of impacted third molar teeth on the panoramic radiographs were documented. Associated disorders and every other indication for surgical extraction was documented. Patients were stratified into three socioeconomic classes using the modified version of questionnaire by chukwuonye et al and Balogun et al. Data were analyzed using a Pearson chi-square test, performed using the Statistical Package for the Social Sciences (version 20; SPSS, Inc, Chicago, IL). A total of 337 patients met the inclusion criteria within the two year study period. The sample consisted of 129(40.9%) male and 208(59.1%) female. The difference between male and female was statistically significant (P= 0.04). Most third molar extraction that was recorded in the third decade of life where 172 (51.0%) cases were recorded. The most prevalent type of impaction recorded was the mesio-angular position (49.9%). The most common pathology associated with impacted third molars was pericoronitis which was recorded in 135cases out of total of 337 patients. Majority of the patients who had third molar extraction belong to the middle socioeconomic class (42.7%) followed by patients in high socio-economic class (40.9%).Third molar impaction was commoner in females than males with mesio- angular impaction being the most common type. It was most commonly found in the third decade of life and pericoronitis was the most common associated pathology. Majority of the studied subjects belong to the middle socioeconomic class.

Study of dividend policy and stock prices in the capital market has attracted considerable interest in corporate finance literature. Theoretical postulates and empirical evidence from country specific and cross-country studies are divided across lines, as some support the existence of a positive significant implication while others submit entirely negative and non-significant implication on the studied topic. Thus, this paper examines Nigerian context of dividend policy impact on market value of quoted commercial banks with study range of 2004-2018. The study is hinged on the theoretical postulates of dividend relevance theory and Efficient Market Hypothesis (EMH). The study employed model stability test and Error Correction Model (ECM) after determining the stationarity status of the time series data employed in the study, using ADF test, while Johansen Co-integration test was used to predict the existence of two long-run co-integrating relationships among variables. The empirical result reveals a significant dividend policy impact on market value of quoted commercial banks in Nigeria. The study therefore, recommends that Central Bank of Nigeria (CBN), Securities and Exchange Commission (SEC) and the established Financial Regulatory council (FRC) to step up regulatory oversight functions to ensure transparency, business ethics and good corporate governance in the banking industry particularly quoted commercial banks in Nigeria, as this will help curtail the anxiety of investors and relatively reduce the practices of declaration of huge paper profits, insider trading, manipulation of stock prices and other nefarious acts.

Background: Reports suggest that HIV-infected patients have elevated D-dimer levels that may be related to chronic inflammation and coagulation abnormalities. Levels of D-dimer have also been reported to be higher in HIV treatment-naïve patients compared to treatment- experienced patients. Methods: Eighty (80) subjects attending HIV clinic at the University of Port-Harcourt Teaching Hospital, Port Harcourt, Rivers state who satisfied the inclusion criteria were enrolled into the study. A commercial assay kit; ELISA Kit for D-Dimer (D2D) (manufactured by Uscn Life Science IncorporatedR USA) was used with a TC96+ ELISA microplate reader (manufactured by Ceco diagnosticR USA) to determine the D-dimer level. CD4 + T-cell count was evaluated using the Partec Cyflow counter-1, a single-platform, three-parameter (SSC plus two-colour fluorescence) desktop volumetric flow cytometer (manufactured by Sysmex PartecR Germany).Full blood count was carried out on the EDTA anticoagulated sample using the Horiba Abx Micros 60 Haematology Analyser (manufactured by Horiba instruments incorporatedR USA). Results: The D-dimer level was found to be lower in HAART- experienced subjects (288.35 ± 129.12 ng/ml) than HAART-naïve subjects (389.85 ± 217.61ng/ml.) (P= 0.013).There was no increase in haematocrit, while the mean WBC count showed increase in the HAART-experienced compared to HAART-naïve subjects. Platelet counts were also increased in the HAART-experienced subjects in comparison to HAART-naïve subjects. Conclusion: This study suggests that D-dimer levels are higher in HIV treatment-naïve patients compared to treatment- experienced patients.

We report a case of assessment of haemodynamics of myocardial bridging (MB) of the right coronary artery using myocardial perfusion imaging (MPI). Although most patients with MB are asymptomatic, some may present with ischemia and related complications, including myocardial stunning, infarction, arrhythmia, AV block, transient LV dysfunction and sudden death and hence it becomes necessary to evaluate the hemodynamics of these patients with MB whether symptomatic or not using MPI which is effective and noninvasive. The index case was a 61 year old man found to have myocardial bridging of the right coronary artery. He had no preceding symptom of ischaemia. Myocardial perfusion imaging however established the presence of inferior wall ischaemia in the absence of any coronary artery lumen narrowing.

Globalization and internationalization has an intense impact on the students’ inclination towards the foreign environment. This research paper focuses on the factors influencing the decision of students to study or work abroad. The factors examined are: level of general knowledge (GK), attraction towards foreign study and work (AT), familiarity with the foreign environment (FM), business informative questions (BA) and repulsive factors that hold him back or create negative image of foreign society (RP). The study is conducted on 201 Saudi male undergraduate students of the Jazan University, Jazan, KSA. The result shows the propensity of students towards the foreign environment. The findings can be generalized to the majority of areas and could be used to create more focused mindset of the students for better prospects.

The general problem of this study was that certain stock market sectors can benefit more than other sectors from seasonality’s (Halloween indicator). It was unclear how seasonality of stock markets impact risk stock strategies while controlling for stock market sectors, when constructing U.S. security portfolios. The purpose of this quantitative, comparative study was to test the influence of a summer and winter effect on the profitability of risk stocks strategies for Standard and Poor’s (S&P) 500 stock portfolios. The research question was: How does seasonality impact the profitability of risk stock strategies while controlling for stock market sectors for U.S. security portfolios? For the analysis a comparison was conducted, while computing the Betas (B), Idiosyncratic Volatility (IV), Capital Asset Price Models (CAPM), annualized returns, and Sharpe ratios for an analysis. A key result of the study was that during the winter months high B and medium B&IV until highB&IV stock selections were the most profitable risk stock strategies and for the summer months low IV, B, IV&B stock selections were most profitable risk stock strategies to trade. The sector selection and the stock selection brought higher returns as reported by other studies, of for example (rStrategy1 = 108.40% annualized return) in this study. Seasonality’s were present in the U.S. stock markets and the investor could capitalize on this effect through a risk stock strategy switch, which is further described in this study and can improve the previous form of investing (i.e., of buying all stocks during winter and changing to Treasury Bill during summer).

The purpose of this study is to examine the balance and attention characteristic of dance exercise. 200 university students with a mean age of 20.63+1.59, who studied at the Faculty of Sport Sciences at Muğla Sitkı Koçman University in the 2016-2017 academic year participated in the study. University students participating in the study were taught 3 hours of Latin dance (salsa, bachata) once a week for 12 weeks. The "d2 attention test", which validity and reliability was performed in Turkish by Çağlar and Koruç [1], developed by Brickenkamp [2], was used to determine students' attention attributes related to dance exercise. Data analysis, frequency analysis, Impulsive statistics. Kolmokorov-Smirnov test, t-test, Mann-Whitney U test were used. As a result, there was no significant difference between the experimental and control groups of the body weight pretest and posttest values of the students participating in the research. A significant difference was found between the experimental and control groups in the balance posttest value. A positive change was determined in the attention, error, and concentration post-test values of the students who participated in the dance study. It has been determined that dance work positively affects balance and attentiveness.

The purpose of this study is to explore the influence of reliability and brand image on purchase intention of sports brands endorsed by entertainers. A questionnaire survey is conducted in this study, and the students from Hsin Sheng Junior College of Medical Care and Management are taken as research objects. A total of 300 questionnaires are sent out; after the deduction of 5 invalid questionnaires, a total of 295 valid questionnaires are collected. In this study, SPSS20.0 for Window Chinese package statistical software is used as the analysis tool. After the verification of descriptive statistics, reliability analysis, independent sample t test, Pearson product difference correlation analysis, and regression analysis, the results obtained are as follows: The reliability of entertainer endorsement has a significant impact on purchase intention, in which the influence of reliable image is greater than the influence of the attractiveness on purchase intention; Brand image has a significant influence on purchase intention, in which the effect of functionality in brand image is greater than the effect of symbolism in brand image on purchase intention; The reliability, brand image, and purchase intention of entertainer endorsement are significantly correlated. According to the results of this study, it is suggested that the selection of endorsers for sports brand companies must be consistent with the positive image of sports brand and have the popular impression, so as to attract consumers’ recognition and expectation of products and provide references for relevant manufacturers.

Oral health services assessment is an ongoing global challenge for improvement of services, quality enhancement and preventing oral diseases. One strategy is to investigate the utilization and access to dental care, and exploring the underlying factors. In Saudi Arabia, only few published studies explored the utilization of dental care services. Hence, this review attempt focusing on the findings of utilization, including manner of use and the associated factors. Only certain possible causes have been studied, and there is limited evidence of the utilization of dental care in Saudi Arabia. Even larger, well-designed studies are needed in order to be a baseline evidence for potential evaluation of progress in dental services after adopting the necessary acts.

Background: Reports suggest that HIV-infected patients have elevated D-dimer levels that may be related to chronic inflammation and coagulation abnormalities. Levels of D-dimer have also been reported to be higher in HIV treatment-naïve patients compared to treatment- experienced patients. HIV infection has also been associated with a decrease in the number of both CD4+ and CD8+ T-cells resulting primarily from a combination of increased apoptosis and decreased lymphopoiesis. Methods: Eighty (80) subjects attending HIV clinic at the University of Port-Harcourt Teaching Hospital, Port Harcourt, Rivers state who satisfied the inclusion criteria were enrolled into the study. A commercial assay kit; ELISA Kit for D-Dimer (D2D) (manufactured by Uscn Life Science IncorporatedR USA) was used with a TC96+ ELISA microplate reader (manufactured by Ceco diagnosticR USA) to determine the D-dimer level. CD4 + T-cell count was evaluated using the Partec Cyflow counter-1, a single-platform, three-parameter (SSC plus two-colour fluorescence) desktop volumetric flow cytometer (manufactured by Sysmex PartecR Germany).Full blood count was carried out on the EDTA anticoagulated sample using the Horiba Abx Micros 60 Haematology Analyser (manufactured by Horiba instruments incorporatedR USA). Results: The D-dimer level was found to be lower in HAART- experienced subjects (288.35 ± 129.12 ng/ml) than HAART-naïve subjects (389.85 ± 217.61ng/ml.) (P= 0.013).The mean CD4+ T-cell count of HAART–naïve subjects was 379.33±287.25 cell/ul and for HAART–experienced subjects was 387.55±334.85 cell/ul. Their mean difference was not statistically significant (P=0.906). Conclusion: It was observed that there was no correlation between D-Dimer and CD4+ T-cell count in HAART-naive and experienced subjects.

Introduction: Sepsis is one of the most common causes of morbidity and mortality in newborns, causing about 46% of global under-five child mortality. In sepsis, C - reactive protein (CRP) is elevated and Phosphate levels are low in blood and severity of hypophosphatemia also relates with poor outcome. The present study aims to measure levels of CRP, calcium (Ca), phosphate (P) and Ca:P ratio in cord blood of neonates with or without sepsis. Methods: Cord blood samples of 60 neonates were enrolled for the study. Samples were divided into two groups on the basis of presence or absence of sepsis in first 24 hrs of birth as decided by pediatrician. Measurement of CRP, calcium, phosphate, Calcium: phosphate ratio (Ca:P ratio) was done. Data so collected was analyzed with SPSS 20 software. Results: Neonates with sepsis had significantly high CRP and low phosphate levels in the cord blood. Ca:P ratio showed significant correlation with increasing CRP levels. Factors which did not show any significant correlation between the two groups were serum calcium levels, gestational age, birth weight and mode of delivery. 81.8% of neonates in group 2 (sepsis group) had phosphate level < 8.8 mg/dl(median level). Conclusion: Elevated CRP levels and Hypophosphatemia is present in neonates with sepsis. There is a negative correlation between serum phosphate and CRP levels. CRP has also been proposed as a diagnostic tool being easily measurable, affordable and convenient. Decreased Ca:P ratio should be taken care of while dealing with parenteral nutrition in such neonates. Phosphate levels must be carefully monitored in such cases.

The research work investigated the effect of leachate sludge waste materials from fish rearing pond on the geotechnical properties of soils from dumpsites. Results of investigations conducted on the control sites at 30m away from each dumpsite of bulk unit weight have incremental percentage values over control sites. Percentage (%) passing BS sieve #200 is higher in dumpsites over control with percentile value increase. Obtained results showed the presence of leachate material affects the physical properties of soil as percentages passing sieve #200 are higher in dumpsite materials. The consistency limits of the control sites of Liquid over plastic limits are summarized into the plastic index (LL-PL=PI), the obtained results indicated reductions values over dumpsites, this indicated that dumpsites leachate materials affected consistency limits of soils with higher values recorded in dumpsites. The entire results of grain size distribution showed that leachate percolation from waste materials affected the distribution properties of soil with dumpsites samples in dominants over control sites. Results indicated reductions in Unconfined compressive strength of control sites, these results showed that the presence of leachate materials has a great effect on soil properties of tested. The California bearing ration results of unsoaked and soaked of dumpsites have higher values over control sites. Results of California bearing ratio obtained showed that the presence of contaminants from waste dumpsites affected the geotechnical properties of tested soil with higher percentage values of dumpsites over control sites. The entire results showed that the presence of fish pond waste sludge has great negative effects on the geotechnical properties of soil.
