Gelatin is a protein substance that is widely used in food and pharmaceutical industries. Gelatin is mainly derived from bovine and porcine sources. Fish gelatin is becoming alternative source of gelatin due to concern on health issue and religious constraints. Numerous studies for identification of gelatin sources have been reported. In this study, Fourier transform infrared (FTIR) spectroscopy was used in combination with chemometrics fuzzy autocatalytic set (c-FACS) to distinguish between bovine, porcine and fish gelatins. The gelatin spectra at Amide and 1600-1000 cm-1 regions were analyzed using c-FACS and the results were compared to principal component analysis (PCA) and linear discriminant analysis (LDA). The results obtained from c-FACS method showed that each bovine, porcine and fish gelatin possessed dominant wavenumbers at 1470-1475 cm-1, 1444-1450 cm-1 and 1496-1500 cm-1 respectively, which represent their unique signatures. Furthermore, a clear distinction for porcine gelatin was observed in coordinated FACS. The c-FACS method is rigor and faster than PCA and LDA in differentiating the gelatin sources. The novel method promises at least another chemometrics method for FTIR related analysis and the possibilities for other applications are endless.
In light of the ongoing global health crisis, the significance of leadership within the healthcare sector has intensified. Given this consideration, the significance of appropriate leadership styles cannot be overstated. The objective of this paper is to critically review published studies on leadership elements in the healthcare sector. Using Bibliometrix R package and VOS viewer, we conducted bibliometric and network analyses on publications retrieved from the Web of Science (WOS) database, with content analysis integrated throughout the paper to deepen understanding. Ultimately, 243 articles were identified as relevant. The findings revealed transformational leadership emerges as the most extensively discussed leadership style. 91% of the articles' theme focus on quantitative research methods. This study synthesizes the influencing factors of the three most frequently discussed leadership styles-transformational, authentic, and ethical leadership-emphasizing the importance of job satisfaction and organizational citizenship behavior. And provides direction for future research through thematic analysis.
Complex systems require rigorous analysis using effective method, in order to handle and interpret their information. Spectrum produced from Fourier transform infrared (FTIR) instrument is an example of a complex system, due to their overlapped bands and interactions within the spectrum. Thus, chemometrics techniques are required to further analyze the data, in particular, chemometrics fuzzy autocatalytic set (c-FACS). The c-FACS is initially used to analyze the FTIR spectra of gelatins. However, in this study, the c-FACS is generalized and implemented for analysis of Coronavirus disease 2019 (Covid-19), particularly, the pandemic outbreak in Malaysia. The daily Covid-19 cases in states in Malaysia are modeled and analyzed using c-FACS, to observe the trend and severity of the disease in Malaysia. As a result, the classification of severity of zones in Malaysia are identified. The obtained results offer descriptive insight for strategizing purposes in combating the Covid-19 outbreak in Malaysia.
