Fermentation Time

Flushing and fermentation times are the two main parameters determining the quality of black tea. In this research, the effects of different flushing and fermentation times were studied on the quality of black tea in two clones, 100 and natural Chinese hybrid. Analysis of variance showed there were the significant differences between the clone types, flushing and fermentation times for theaflavin, thearubigin, total color, brightness, tannin and caffeine. Correlation coefficients between all studied traits, except thearubigin and brightness, caffeine and brightness, and total colour and theaflavin/thearubigin ratio, were significant at 1% probability. Regression analysis indicated there was a significant linear regression between fermentation time and brightness, tannin, and theaflavin/thearubigin ratio. Also, multiple regression analysis for brightness and total colour indicated that more than 70% of the variation in brightness was explained by theaflavin, caffeine and theaflavin/thearubigin ratio, and more than 68% of the variation in total colour was because of caffeine and theaflavin/thearubigin ratio.

The Impact

The purpose of this study is to examine the impact and the electronic service quality of the national zakat management information system (SIMBA) on the national zakat collection. This paper uses a multiple regression analysis in its explorative attempt to illustrate the impact of SIMBA implementation on the national zakat collection. It shows that SIMBA is positive and significantly impact the national zakat collection as well as the human development index that is used as a proxy for the human resource management quality of zakat institutions in the respective city. Nonetheless, the population is negative and significant to the zakat collection as endemic poverty and reluctance to pay zakat are indicated as the reasons. Moreover, this study has succeeded in adapting and conducting e-service quality survey to zakat information system realm. All the tests prove that the instrument in this study has a high degree of reliability and validity. The results show that some of the demographic factors significantly impact the perceived performance of SIMBA. Multiple regression analysis that is conducted in this study shows that e-service quality dimension is positive and significant towards SIMBA’ overall quality, perceived value, and loyalty intention. This study contributes to the zakat management system literature, especially in the impact of the national zakat information system, which is pivotal in enhancing zakat collection and poverty alleviation program funded by zakat.

Abstract Backgroud: As the survival rates of cancer patients have been increasing due to early diagnosis and technological advances in treatment, their caregiver burden has also emerged as an important issue. In view of this situation, this study aims to investigate the unmet needs and quality of life of caregivers of Korean breast cancer survivors.Methods: A multicenter cross-sectional interview survey was performed among 160 caregivers of Korean breast cancer survivors. Caregivers who gave written informed consent to participate completed the Comprehensive Needs Assessment Tool for Cancer Caregivers and EuroQol-5 Dimensions. Data were analyzed using the t-test, ANOVA and multiple regression analysis.Results: The mean age of the caregivers was 46.4 years, 44.4% (71/160) were spouses of patients, and 52.5% (84/160) were personally taking care of cancer survivors. Unmet needs were highest in the ‘healthcare staff’ domain (mean ± SD: 1.69 ±1.11), and the item with the highest level of unmet needs was ‘needed information about the current status of the patient’s illness and its future courses’ (1.98 ± 1.04). Unmet needs were correlated with age, educational level, marital status, employment, religion and psychosocial status. Poorer quality of life was closely related to higher levels of unmet needs. In multiple regression analysis, age, employment, religion, and levels of stress and despair were closely associated with unmet needs.

Abstract INTRODUCTION Aims of awake surgery are considered as maximum resection and functional preservation for postoperative quality of life (QOL). However, any studies have not been focused on the fundamental hypothesis that preservation of brain functions contributes to patient’s QOL. In this study, we investigated postoperative QOL and its related factors to reveal contribution of awake surgery for maintaining QOL. METHODS A total of 63 patients who underwent awake surgery were studied. Several kinds of neuropsychological/neurological tests and SF-36 to assess QOL were performed at 6-month postoperatively. In SF-36, 3-component scores, including physical, mental, and role/social component were calculated and they were compared with healthy volunteers. Additionally, their background factors were collected from medical records. Then, influenced background and functional factors to QOL were analyzed using multiple regression analysis. Moreover, voxel-based lesion symptom (VLSM) analyses were performed to investigate relationship between resected regions and QOL. RESULTS Though physical and mental QOL scores were almost equivalent to healthy volunteers, role and social component score (RCS) were significantly declined (36.7, < .0001). Using multiple regression analysis, RCS significantly related to reinstatement among several background factors (p=0.0038). Until postoperative 6 months, 71.6% returned to professional work. Moreover, RCS correlated significantly with working memory, language, and motor function among several brain functions (p=0.019, 0.0028, 0.010, respectively). In the VLSM analysis, patients who resected following regions showed significantly low RCS; the left inferior frontal and superior to middle temporal gyri which relate to language; and right supplementary motor area and cingulate cortex which are involved in motor control or working memory. CONCLUSIONS The important factors to maintain QOL are reinstatement and preserving brain functions including language, motor, and working memory. This suggests that awake surgery aiming for preserving these functions is a benefit for postoperative QOL.

Abstract Objective: To construct a harmony box based on correlated cephalometric variables, which may serve as a valuable diagnostic tool in orthodontic treatment planning, by analyzing the harmonious relationships of existing individual craniofacial patterns among Filipinos. Materials and Methods: Eighty-one subjects, 37 females and 44 males, were selected from the student population of a University according to established inclusion criteria. Five cephalometric angular measurements were obtained and digitized. Pearson correlation coefficients described the high association among the five variables. The bivariate linear regression analysis was used to construct a harmony box, which contained the cephalometric floating norms of the five correlated variables. Multiple regression analysis and the standard error of the estimate were calculated to construct the harmony schema, which describes the individual craniofacial pattern. Results: Correlations between the five variables were significant at .001 and .05 levels. Linear regression equations with corresponding r2 and standard error of the estimate (SE) were illustrated as the harmony box. The multiple correlation coefficient R, the adjusted R2, and the SE when one of the five measured variables was predicted from the remaining four by means of a multiple regression analysis were displayed as the harmony schema. Conclusion: The cephalometric floating norms describing the individual craniofacial pattern among Filipinos were established based on five correlated variables in the form of a harmony box.

A role-conflict approach was employed to explore the impact of perceived frequency of conflict between caregiving and other obligations on the quality of relationships between daughters and their care-receiving mothers. Frequency of conflict between caregiving and responsibilities as a wife, mother, and paid and unpaid worker was assessed. Daughters reported relatively infrequent conflict between caregiving and other obligations. A multiple regression analysis revealed that daughters who reported frequent conflict between their obligations as caregivers and their obligations as wives had poorer relationships with their mothers. The findings emphasize the importance of a supportive spouse for married caregivers.
