Background and Objectives : Vocal fold hemorrhage occur by blood accumulation in Reinke's space by vocal trauma. It is mostly asymptomatic, but in some cases it may cause severe dysphonia. It is often seen in patients who use their voice professionally. However, recent changes of life style affected the phonation in general population. We studied to know what are the causes and what are the major factors to affect the vocal fold hemorrhages. Materials and Methods : 19 subjects were evaluated by using of questionaire and laryngoscopic examinations. We evaluated the factors to lead the change in voice directly, underlying causes, occupations and laryngeal findings. Results : The direct causes of the vocal fold hemorrhages were clearing throat, talking, coughing and singing. Reflux laryngitis and upper respiratory infection were the underlying diseases. Vocal fold hemorrhages were developed during the menstruation in 5 patients. Accompanying functional voice disorders were seen in 13 patients, such as, vocal fold nodule, nodule with varix, vocal polyp, Reinke's edema. Patients with reflux laryngitis had the habits of clearing throat as the direct cause of the vocal fold hemorrhages and had hyperkinetic functional voice disorders. Voice abuse was the direct cause of the vocal fold hemorrhages in patients who was in the period of the menstruation. The most common site of the hemorrhage was at the membranous portion of the vocal folds. Conclusions : Authors thought the forceful laryngeal activity was the cause of the vocal fold hemorrhages. And reflux laryngitis and menstruation was the risk factors of the vocal fold hemorrhages.

Background: Ecologists continue to investigate the factors that potentially affect the pattern and magnitude of tree damage during catastrophic windstorms in forests. However, there still is a paucity of research on which trees are more vulnerable to direct damage by winds rather than being knocked down by the fall of another tree. We evaluated this question in a mixed hardwood-softwood forest within the Big Thicket National Preserve (BTNP) of southeast Texas, USA, which was substantially impacted by Hurricane Rita in September 2005. Results: We showed that multiple factors, including tree height, shade-tolerance, height-to-diameter ratio, and neighborhood density (i.e., pre-Rita stem distribution) significantly explained the susceptibility of trees to direct storm damage. We also found that no single factor had pervasive importance over the others and, instead, that all factors were tightly intertwined in a complex way, such that they often complemented each other, and that they contributed simultaneously to the overall susceptibility to and patterns of windstorm damage in the BTNP. Conclusions: Directly damaged trees greatly influence the forest by causing secondary damage to other trees. We propose that directly and indirectly damaged (or susceptible) trees should be considered separately when assessing or predicting the impact of windstorms on a forest ecosystem; to better predict the pathways of community structure reorganization and guide forest management and conservation practices. Forest managers are recommended to adopt a holistic view that considers and combines various components of the forest ecosystem when establishing strategies for mitigating the impact of catastrophic winds.
Purpose: The purpose of this study was to investigate post-traumatic stress, job stress, fatigue, and social support of nurses in direct care for COVID-19 patients and to identify the factors affecting post-traumatic stress among the nurses. Methods: The participants were 150 nurses from three hospitals. Data were collected from September 11, 2020 to September 21, 2020. The data were analyzed with SPSS/WIN/25.0 program. Results: The mean score of post-traumatic stress was 22.27±15.49 (range 0~88). The percentage of high risk group of post-traumatic stress was 35.3%, risk group was 20.0%, normal group was 44.7%. Post-traumatic stress showed statistically significant differences according to quarantined experience (t=2.15, p=.033), and provision of COVID-19 manual (t=-2.40, p=.026). Post-traumatic stress was positively correlated with job stress (r=.48, p<.001), and fatigue (r=.58, p<.001), and it was negatively correlated with social support (r=-.22, p=.005). Job stress was positively correlated with fatigue (r=.74, p<.001), and it was negatively correlated with social support (r=-.17, p=.030). Fatigue and social support (r=-.17, p=.029) had a negative correlation. The results of regression analysis showed that the factors affecting post-traumatic stress included fatigue (β=.56, p<.001), provision of COVID-19 manual (β=-.24, p<.001), and quarantined experience (β=.18, p=.006) and that the total explanatory power was 42.0%. Conclusion: In this study, fatigue, provision of COVID-19 manual, and quarantined experience were found as influential factors of post-traumatic stress among nurses in direct care for COVID-19 patients. Therefore, development of the intervention for reducing the fatigue should consider to prevent post-traumatic stress in nurses. Also, provision of COVID-19 manual for nurses and psychological intervention program for nurses experienced quarantine are necessary.
Purpose: The purpose of this study was to analyze factors influencing health-related quality of life (HRQoL) among male adults. Methods: Participants were 196 male adults who were recruited from June to July 2016. Seven variables related to HRQoL including age, perceived stress, physical activities, problem drinking, social support, self-esteem, depression were measured. Data were analyzed using the SPSS/WIN 20.0 program and Amos 18.0 for descriptive statistics, Pearson correlation coefficients and path analysis. Results: The mean for HRQoL was 80.14. The path analysis showed that depression had the greatest direct effect on HRQoL. It was found that perceived stress had direct and total effects on HRQoL. It also mediated the paths of social support and self-esteem to HRQoL. These factors account for 68% of the total variance, and the fit indices of the model satisfied the criteria of fitness. Conclusion: The results indicate that these factors influencing HRQoL should be considered when developing programs to improve HRQoL for male adults.

The paper aims to investigate auditors, auditing firms and other external factors that affect quality of information technology audit in Vietnam. We conducted 2 types of data collections including direct and on survey. For direct survey, we sent directly to auditors at the training classes organized by State Securities Exchanges Commission. An online survey was established and Google doc link was provided to the Big4 and non-Big4 auditors. We received 138 survey responses in that 90 auditors came from Big4 and 48 auditors from non-Big4 firms. The data are analyzed using a factor analysis and compare means approaches to illustrate the potential IT audit quality factors and identify differences between two groups of auditors. The results show that independence and accounting knowledge and audit skills are the most important factors. And since external auditors perform many assurance services, the independence is critical. The result also shows that the auditors need to have enough competent and professional skills when conducting an audit, especially within an IT environment that requires high quality. The findings suggest a similar pattern of two groups in the context of Vietnam and some factors of auditors and auditing firms appear to have a statistically significant impact on quality of IT audit.

The study investigates the impact of strategic planning (SP) factors on service quality (SQ) in private universities (PUs) in Oman and how they fit together in the development of higher education institutions (HEIs). The reports of the Ministry of Higher Education (MoHE) in Oman revealed that the service quality in private universities is unsatisfactory. This study employs a quantitative method. Data were collected from a sample of 730 academics and administrators. Structural Equation Modeling (SEM) based on AMOS software was applied for data analysis. The results of the structural paths showed that, among the strategic planning factors, only environmental scanning and leadership had a direct significant impact on service quality. However, mission statement and participation had insignificant direct impact on service quality. The findings suggest that environmental scanning and leadership are critical factors in predicting service quality dimensions of private universities. The findings add to the body of knowledge particularly in the Omani context, which can be useful in the neighboring countries as well. The study combines two different popular models in addressing service quality. The study also clarified the importance of each factor of the strategic planning process, which give a comprehensive picture of the university.

This study is an attempt to identify factors determining the success of international standardization and understand the relationship between the factors, such as government-driven standardization activities. Six factors were identified through factor analysis; namely, 'Direct government support', 'Indirect government support', 'Utilization of standardization bodies', 'Standardization strategy', 'Attainment of a dominant market power', and 'Adoption as an international standard.' The results showed that firstly, support from the government, whether direct or indirect, had no direct effect on the outcome of international standardization efforts, but produced an indirect influence on it through mediating factors such as the attainment of a dominant market power. Secondly, the attainment of a dominant market power proved to be the most important success factor of international standardization, suggesting that the government must direct its efforts to help boost the market power of target standards through measures like promoting a timely market entry and the development of high-quality standards, in a manner to induce market satisfaction, increasing lock-in effects and building a quasi-vertical integration system. Thirdly, direct support from the government holds the key to the success of international standardization with de jure standardization bodies, while the strategic use of standardization bodies appears the most important for the positive outcome of standardization concerning de facto standardization bodies.
This study aims to examine the educational function space of university dormitories at local universities with corridor centered structure in Honam area regions based on direct and indirect parameters on the whole satisfaction of users in residential environment factors and personal characteristics. First, according to relations among parameters, educational and cultural activities of four major activities within the dormitory had indirect influences on social activities, eating and sleeping activities had no direct influence on other activities. And social activity had direct influence on the general satisfaction as an important parameter and educational and cultural activities had indirect influence on the whole satisfaction through social activities. Detailed results show that, in the first educational activities directly affecting the lighting and air conditioning facilities (0.22), safety (0.326), Territoriality (0.327), the space density (-0.167), directions (-0.166) and yeohyang having personal characteristics and the safety of the second cultural activities (0.183), Territoriality (0.361), Aesthetics (-0.13) and the personal characteristics Sex (-0.179), the direct effect, third, and erosion has a direct impact on activity The flexibility of the space factor (-0.128) and Territoriality (0.38) and the personal characteristics grade (0.172), respectively. Fourth in social activities directly affecting the pathfinding (-0.104), and parameter, education (0.388) and cultural activities (0.445), and some of the factors affecting the indirect lighting and air conditioning facilities, safety, and Territoriality, the space density, directions, grade, they could influence through educational activities to be analyzed. That is, territoriality in educational function space is the important factor that users react very sensitively in educational, eating and sleeping activities and educational function space must secure area and division considering personal and public use as the space accommodating activity which is lacking in unit residential space. Accordingly, the safety of educational function space in university dormitory is considered as the fundamental safety matter on the fire prevention, hygiene and cleanness for users in the satisfaction of educational and cultural activities.
Consumers who purchase products from foreign countries and deliver them back to Korea are increasing. According to the Korea Fashion & Textile News (2015), overseas direct shopping reported 39% increase compared to 2013. Furthermore, clothes accounted for 19% of product category. Therefore, the service quality of overseas purchase sites is becoming more important, but studies have been limited. this research focuses on investigating the effects of consumers' shopping orientation on service quality and the effects of service quality on trust, satisfaction, and consumer loyalty. The survey was administered to consumers who had experiences in purchasing through overseas direct purchase websites. The results showed that the perception of service quality differed depending on the respondent's shopping orientation. Among the four shopping orientation groups(shopping confidence, shopping enjoyment, trend pursuit, and shopping follower groups), the shopping confidence group showed the highest mean for all service quality factors. All the groups showed the highest scores on product and trust among the factors of service quality. Next, the results revealed that service quality positively influenced consumers' trust on websites that provide overseas direct purchase services, which further improved customer loyalty. Therefore, the study gives managerial suggestions to online retailers that provide oversea shopping service. They need to provide higher site efficiency, security, product reliability, and responsiveness to cultivate international customers' trust and satisfaction. In particular, it will be important for them to offer accurate, reliable product information and various languages for overseas customers.
The purpose of the direct cortical and subcortical stimulation technique is to prevent false positives caused by transcranial electrical motor evoked potentials (TceMEP) in surgery on patients with brain tumors that have occurred around the motor cortex and to preserve the correct mapping of motor areas during surgery and the corticospinal tract. In addition, it reduces the trial and error that occurs during the intraoperative neurophysiological monitoring (INM) process and minimizes the test time, so that accurate information is communicated to the surgeon with quick feedback on the test results. The most important factors of this technique are, first, examination at a stimulus threshold of a certain intensity, and second, maintaining anesthesia depth at an appropriate level to prevent false positives from occurring during surgery. The third is the installation of a multi-level channel recording electrode on the opposite side of the area of operation to measure the TceMEP waveform and the response to direct cortical and subcortical stimulation in as many muscles as possible. If these conditions are maintained, it is possible to predict causes that may occur in other factors, not false positives, from the INM test.
