Some of scheduling systems will integrate a database for effective access of editing, viewing and recording amount of data. However, poor scheduling practices would cause undesirable time redundancy and inefficient process just to schedule a timetable for the lecturers and students. Poor scheduling also can cause a misunderstanding between lectures such as double-assignations of lectures, cancellations of presentations, clash in class schedule, prolonged postponement as well as inefficiency in terms of resources and time. A good scheduling system could generate optimal presentation of timetables and enable a direct interaction between lecturers and administration staff that will take into account all the constraints such as to check availability of time and place of events and real-time updates that will help data handling accuracy, cost effective and efficient time management.  Therefore, this study will make a comparison and execute a standard process of scheduling framework for future practice in academic industry. This paper presents a practical method for making a comparison based on the studies on existing scheduling system.","PeriodicalId":21574,"journal":{"name":"Science Proceedings Series","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81594879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A questionnaire survey is employed to collect information.  The number of usable sample of this study is 644 respondents. This study investigated trends in psychiatric disorders such as anxiety, stress, depression, and the CO19 pandemic. In addition, the study also tries to identify the course of mental disorders of the respondents. We found that lifestyle issues, job shifts, and financial problems have contributed to a rise in the respondents’ mental health. Lifestyle has a negative correlation to the degree of stress with mental illness, while education also has a significant impact on the mental wellbeing of the respondents. ","PeriodicalId":21574,"journal":{"name":"Science Proceedings Series","volume":"114 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82429276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodiesel is a promising alternative fuel derived from animal fats or vegetable oil through transesterification with methanol. Base catalyzed transesterification is the most commonly used technique as it is the most economical process. Presently, a lot of heterogeneous catalysts have been formulated that are more effective than the homogeneous catalysts. CaO/Al2O3 was synthesized using incipient wetness impregnation method. The biodiesel was developed and optimized using Box-behnken response surface methodology (RSM) design provided using MINITAP-17 statistical software. The four independent variables considered are: reaction time, methanol to oil ratio, reaction temperature and catalyst concentration. The response chosen was fatty acid methyl ester (FAME) yields which were obtained from the reaction. The result from analysis of variance (ANOVA) showed a satisfactory result. Moreover, the input variables showed greater significance on the response which are reaction time and temperature base on F and P-value. The statistical models developed for predicting biodiesel yield revealed a significant agreement between the experimental and predicted values (R = 0.9686). An optimum methyl ester yield of 93.29 % was achieved with optimal conditions of methanol/oil molar ratio of 6:1, temperature of 600C, reaction time of 120 min and catalyst concentration of 1.0 wt%.

This study tends to investigate the inadequate adoption of requirements negotiation process models. Further, it finds the acceptance criteria for the software industry to adopt requirements negotiation models. Finding shows that the software industries do not adopt the process models.

However the usage of the synthetic dyes can reduce the harmful effect to the human health and environment. The henna leaves have various advantages because it is non carcinorgenic and environment friendly. The composition of natural dyes for the dyeing process on the cotton fabrics are 10g, 20g, 30g, 40g, 50g, 60g, 70g and 80g with 40ml of distilled water.
