Background. The natural course of Legg-Calve-Perthes disease (LCPD) in children with subtotal or total lesion, which correspond to group III-IV according to the Catterall classification, it often leads to hip subluxation. Any changes in the vertebral-pelvic complex lead to mutual transformation and aggravation of existing deformities. In the Russian literature, there are no data on the assessment of the state of the frontal and sagittal spino-pelvic ratios in children with hip subluxation in LCPD. Purpose to evaluate the radiological parameters of the frontal and sagittal spino-pelvic relations in children with hip subluxation in LCPD. Materials and Methods. The study is based on the results of radiometry of 20 patients (20 hip joints) at an average age of 8.90.6 years with LCPD. Radiometry of the main frontal and sagittal spino-pelvic indices was performed and the type of vertical posture was determined according to P. Rousoully, as well as correlations between the studied parameters. Results. All patients had a pelvic distortion in the frontal plane. The values of PI had insignificant changes in comparison with similar values in the asymptomatic child population, the values of SS and SSA exceeded them, and the values of PT were significantly lower, which indicates the presence of excessive pelvic anteversion. The GLL values significantly exceeded the average statistical indicators. The global sagittal balance indicator (SVA) had negative values. The correlation analysis showed the presence of a strong positive relationship between PI and SS, SS and GLL, SSA and SS, a moderately pronounced positive relationship between PI and PT and a moderately pronounced negative relationship between PO and SS, PO and GLL. Conslusion. In children with LCPD in the fragmentation stage with subtotal or total epiphysis lesion (Catterall group III-IV) and hip subluxation, excessive pelvic anteversion is characteristic, which is expressed in an increase in the angle of inclination of the sacrum (SS) in combination with hyperlordosis of the lumbar spine and negative imbalance, as well as a pelvic distortion towards the affected limb. The totality of these changes corresponds to the IV type of vertical posture according to R. Roussouly, which can contribute to the development of degenerative-dystrophic processes in the lumbar spine.

Massively Multiplayer Online Game (MMOG) dependency has been widely studied but research results suggest inconclusive antecedent causes. This study proposes and empirically tests three predictive models of MMOG dependency using a survey of online gaming participants. It finds multimedia realism for social interaction serves as an original antecedent factor affecting other mediating factors to cause MMOG dependency. These mediating factors derive from Uses and Gratifications theory and include: (1) participation in a virtual community, (2) diversion from everyday life, and (3) a pleasant aesthetic experience. Of these, participation in a virtual community has a strong positive relationship with MMOG dependency, and aesthetics has a modest negative relationship. Moderator analyses suggest neither gender nor “frequency of game playing” are significant but experience playing online games is a significant moderating factor of MMOG dependency.

Objective. To develop a quick, simple, bedside test for determining continuous positive airway pressures (CPAP) for obstructive sleep apnea (OSA) patients.Study Design. Prospective case series at a tertiary medical center.Methods. The Five-Minute Awake Snoring Test for Determining CPAP (Five-Minute CPAP Test) was developed and tested. Patients wear a soft-gel nasal triangle mask while holding a tongue depressor with the wide section (1.75 cm) between the teeth. Fixed pressure nasal CPAP is applied while the patient simulates snoring at 4 centimeters of water pressure. The pressure is incrementally titrated up and then down to determine the lowest pressure at which the patient cannot snore (Quiet Pressure).Results. Overall, thirty-eight patients participated. All could simulate snoring. Correlation coefficients were statistically significant between Quiet Pressures and body mass index (rs=0.60[strong positive relationship],p=0.0088), apnea-hypopnea index (rs=0.49[moderate positive relationship],p=0.039), lowest oxygen saturation (rs=-0.47[moderate negative relationship],p=0.048), and oxygen desaturation index (rs=0.62[strong positive relationship],p=0.0057).Conclusion. This pilot study introduces a new concept, which is the final product of over one year of exploration, development, and testing. Five-Minute CPAP Test is a quick, inexpensive, and safe bedside test based on supine awake simulated snoring with nasal CPAP.

This study examines the relationship between liquidity, growth and profitability of non-financial firms listed on the Bursa Malaysia. Specifically, this study examines the relationship between liquidity and growth on profitability for 50 non-financial public listed firms in Malaysia. Using panel data technique on 250 observations across a five-year period, this study shows that liquidity has a strong positive relationship with profitability in terms of return on asset of the firms. However, liquidity in terms of quick ratio has no impact on profitability. This study also shows that firm growth in terms of sales growth has a negative relationship with profitability. However, this study shows that liquidity and growth in general do not influence profitability in terms of return on equity, although the result shows that sustainable growth rate has a positive relationship on profitability. This study highlights the importance of these measures in measuring performance. The findings in this study provide guidelines to the firms on the measures that best to be used in evaluating performance so that appropriate strategies can be adopted to increase performance.

The main objective of the paper is to analyze the influence of microfinance on entrepreneurial success of Zimbabwean SMEs. Adopting explanatory research design with a sample that constitutes 120 business owners of SMEs in Gweru district data collection was through questionnaire administering that used Likert scale-type questions. The hypotheses are analyzed using Spearman's correlation and regression analysis in order to empirically establish the influence of microfinance on entrepreneurial success. The main regression results show a strong positive relationship between microfinance and entrepreneurial success, a weak negative relationship between the business owner's age and entrepreneurial success, and a positive relationship between the level of studies and entrepreneurial success of Zimbabwean SMEs.

AbstractThe notion that Paleoindians used bifaces as “mobile cores” is widespread in Late Pleistocene lithic research, although it can be difficult to test empirically. Here, we use experimental replication to establish two quantitative predictions that would be indicative of biface-core transport. If bifaces are being used as mobile cores, then we should see among a group of sites of varying toolstone procurement distances (a) a negative relationship between toolstone procurement distance and the mean unifacial tool maximum-thickness value from each site; and (b) a negative relationship between toolstone procurement distance and the variability (standard deviation) of maximum flake thickness values from each site. We then test these predictions against data from six Clovis sites of varying toolstone procurement distance in the Lower Great Lakes region. The results show that both sets of data possess a strong, positive relationship with increasing toolstone procurement distance, which is inconsistent with the notion that biface-cores were transported. Since the Clovis presence in the Lower Great Lakes is widely acknowledged to be a colonization pulse, we conclude that the lack of biface-core transport there is an economizing and risk-mitigating behavior consistent with the models of Kuhn (1994) and Meltzer (2002, 2003, 2004).

In this article the authors examine the effects of allocentrism and consumer ethnocentrism (CET) on intentions to purchase domestic versus imported products, focusing on the current phenomenon of the “Korean Wave” in Taiwan. Results based on data collected from 433 mall intercept interviews in Taiwan indicate that there is a strong positive relationship between allocentrism toward parents and CET. However, a significantly negative relationship between allocentrism toward friends and CET was also found. It was also found that friends' in-group attitude toward Korean television dramas has a mediating effect of allocentrism toward friends on CET and CET on intention to buy Korean products. In this study, it was found that CET played a mediating role between allocentrism toward parents and friends and purchase intention. This ethnocentric effect was attributed to parental and friends' in-groups which significantly enhanced and reduced, respectively, the impact of intergroup discrimination, making national identification a less obvious and important social category. These findings have significant implications for domestic and foreign marketers.

The analysis of the College Board's Advanced Placement (AP) enrollment focused on marginalized populations' (i.e., African American, Hispanic, and poor students) limited access and the schools' efforts to bridge the gaps. Little research has been done on marginalized populations' AP passage rates. The researchers of this correlational study investigated AP enrollment and passage rates in public and charter high schools in Florida (n = 355) by comparing the enrollment and passage proportions amongst Caucasian, African American, and Hispanic students as well as the proportions of students who received free or reduced lunch. The results showed a weak, positive relationship between proportions of Hispanic, African American, and Caucasian students passing AP exams and the proportion of AP students enrolled. There was a strong, positive relationship amongst the proportions of African-American, Hispanic, and Caucasian students who passed the exam. However, a weak, negative relationship was found between the proportions of students who were enrolled in AP classes and those who received free or reduced lunch. There was also a negative relationship between Hispanic, African American, and Caucasian students passing the AP exam and the percentage of the school's population enrolled in free or reduced lunch. The findings suggest that schools with high poverty rates have a low enrollment rate of students in AP courses. The focus on AP enrollment rates for minority students has led to increased rates of minorities successfully completing advanced coursework, but there is still a need for similar focus on high poverty schools.

Area of the Study As a significant determinant of career success of employee, this study is discussing the relationship between Personality Five Factor theory and the Career Success of executive workers in the apparel sector organizations in Sabaragamuwa province Sri Lanka.Problem of the Study There is an empirical knowledge gap in the context of the impact of personality five factor theory on the career success of employees in Sri Lanka. therefore, the problem of the study is: Does Five Factor Theory of personality affect to the career success of executives in the apparel sector organization in Sabaragamuwa province.Method of the study The data were collected from a selected sample of 122 executives in the apparel industry in Sabaragamuwa province Sri Lanka by administrating a structured questionnaire, which consisted of 63 questions/ statements with 5 points scale. The data analyses included the univariate and bivariate analyses.Findings of the Study The authors found that some of the factors have strong positive relationship and some have negative relationship and some haven’t any relationship with career success of executives in apparel sector organizations in Sabaragamuwa province, Sri Lanka. Extraversion and Conscientiousness have strong positive relationship with career success of the executives and Agreeableness and Neuroticism have negative relationship with the executives of the apparel sector organizations. However, there is no any relationship in Openness to experience with career success of the executives.Conclusion of the Study Future research based on the current theoretical model can investigate the relationship of personality with other work related behaviors and outcomes. The empirical confirmation of this conceptual model is another area of future research. Future research should attempt to replicate these results and develop process models that may explain why conscientiousness and Extraversion have such apparently enduring associations with career success.Keywords: Personality Five Factors, Career Success, Executives, Apparel Sector Organizations

In order to establish a future engagement of the Indonesian market in terms of coconut flour, awareness of the product is needed for the consumer decision making to purchase the product which will lead to future engagement. This study aims to examine the effects of product and awareness and consumer decision making towards future engagement in Indonesia. By employing SmartPLS, we prove that existence of product has a relatively strong negative relationship with awareness (.55); while awareness has a relatively weak relationshipwith consumer decision making to purchase a product (.37) and the decision made by customer to purchase healthy product have a relatively strong positive relationship towards engagement of the product in the future (.66). Further implications are discussed.
