Present study was conducted to improve microencapsulation process of Clostridium tyrobutyricum (Ct) by optimizing process parameters to improve its in-vitro characteristics over that of free cells. All process parameters including wall material (w/v concentration: modified starch 3-7%; gelatin 2-6%; maltodextrin 3-7%), sample flow rate (250-450 mLh-1) and inlet air temperature (105-145°C) were analysed through single factor analysis. Response surface design test was used to develop multiple quadratic regression equations to fit the functional relationship between factors and response values and to choose the optimal conditions. The optimal conditions for maximum survival rate (82.030%) of encapsulated Ct were: 4% gelatin, 5% modified starch and 5% maltodextrin concentration with sample flow rate of 350 mLh-1 at inlet air temperature of 105°C. Encapsulation reduced the survival loss of Ct from 1.990 to 1.080 lgCFUg-1 under strong acidic condition (pH1) than free Ct. Survival loss of free Ct was 31.914% more than encapsulated Ct under high temperature treatment (90°C). Similarly, protected Ct showed higher survival rate under simulated gastric condition with long storage life. Encapsulation of Ct through optimized spray drying method efficiently improved its survival rate under strong acidic or high temperature environment with safe transit through gastrointestinal tract and also eradicates the technological limitations which preventing the use of many probiotic strains

Kutatásunk célja a vállalati társadalmi felelősségvállalást befolyásoló tényezők hatásainak elemzése. Kvantitatív vizsgálatot folytattunk, melynek megalapozása során a vezetői személyiség, a vállalati kultúra és a humán menedzsment működési sajátosságait elemeztük. A kutatás 2020 őszén zajlott Magyarországon. Vállalati vezetők és HR szakemberek töltötték ki kérdőívünket, számítógéppel támogatott adatgyűjtést végeztünk. A kapott 37 választ a kismintára érvényes statisztikai szabályok szerint elemeztük. Eredményeinket a COVID-19 járvány hatásai befolyásolták, a vállalati CSR tevékenység a recesszió hatására háttérbe szorult, de a vezetők attitűdje nem változott, csak a lehetőségek szűkültek. Corporate Culture, Management Personality, HR Organization and Corporate CSR Activities I. Our research aims to analyze the effects of factors influencing corporate social responsibility. We conducted a quantitative study, in the course of which we explored the operational characteristics of the managerial personality, the corporate culture and human resource management. The research took place in the autumn of 2020 in Hungary. Company executives and HR professionals completed our questionnaires, and we conducted computer-assisted data collection. The 37 responses received were analyzed according to the statistical rules applicable to the small sample. Our results were affected by the effects of the COVID-19 epidemic. Corporate CSR activity was pushed into the background due to the recession, but the attitude of managers did not change, only the opportunities narrowed. Keywords: social responsibility, managerial personality, HR activity, corporate culture

Background: In coronary artery bypass grafting (CABG), the patency of venous sequential graft remains controversial. Hemodynamic factors have been proved to be the important factors influencing graft patency. The objective of this study is to compare the patency of sequential grafts and normal grafts by hemodynamic environment. Methods: This study used a patient’s clinical data to construct a 0D/3D coupled multi-scale model, and used this model to calculate graft’s hemodynamics under two grafting methods. Meanwhile, CABG ideal models were constructed based on grafts’ flow data of 60 patients (63 normal grafts, 19 sequential grafts) to calculate grafts’ hemodynamics. Results: Based on the multi-scale model, it was found that the sequential graft flow and time average wall shear stress (TAWSS) were higher than normal graft, which was good for graft patency. But there were a flow separation region, some regions of high oscillatory shear index (OSI) and relative residence time (RRT) in sequential graft, which could lead to intimal hyperplasia. Based on ideal CABG models, it was known that failure rate of sequential and normal grafts were 36.8% and 36.5%, and there were significant differences between them in flow rate, TAWSS and OSI (sequential versus normal: flow rate (ml/min): [Formula: see text] versus [Formula: see text], TAWSS (Pa): [Formula: see text] versus [Formula: see text], OSI: 0.[Formula: see text] versus [Formula: see text]). Conclusion: For saphenous venous graft (SVG), although the normal graft has similar patency with the sequential graft, the hemodynamic mechanism behind it is different. In flow rate and WSS, sequential grafts have an advantage over normal grafts. But there are high OSI and RRT regions in sequential grafts.

Basing on the analysis of contemporary literature sources, the category “financial behavior of population” is defined. Analysis of the factors influencing financial behavior of households under the conditions of ongoing crisis is carried out. Our quantitative study was carried out to identify the motives behind the financial strategy and the reasons limiting the financial behavior of population. Trends in the use of monetary incomes by population have been revealed, dynamics of the structure and the volume of savings has been shown. Transformations of financial strategies of households during the crisis are also demonstrated. A typology of households was developed according to the criterion of money management depending on sociodemographic characteristics, taking into account the age of the respondents, their financial standing and also their lifestyle. The purpose of this study is to determine the contents, the structure, characteristics, dynamics and other factors of financial behavior of a mass actor on the example of the Tyumen region.

The concept of E-procurement has been widely spread with the growing use of informational technology in every field. Organizations are adopting methods of procurements that are more reliable, less time consuming and relatively stronger than the traditional methods. This quantitative study investigates factors influencing e-procurement practice in Karachi, Pakistan. A sample of 319 respondents was taken to observe the influence of internal organizational support, integration with suppliers’ electronic systems, supplier willingness, perceived improvements to purchasing tasks and supplier pressure on e-procurement intention. The results information indicates that internal organizational support, supplier willingness and perceived improvements to purchasing tasks significantly influences e-procurement intentions. However, the factors integration with suppliers’ electronic systems and supplier pressure does not have any significant impact on e-procurement intention. The result recommends the use of e-procurement system for organizations to facilitate the current practices of procurement.

Background. Human immunodeficiency viruses (HIV) / Acquired immunodeficiency syndrome (AIDS) is one of the most significant public health challenges in Surabaya, Indonesia where the greatest number of people living with HIV/AIDS (PLWHA) among key populations is in areas served by Sememi Public Health Center. HIV-infected persons have a greater risk for developing dental caries, such as salivary gland enlargement, and decreased salivary glands function. Given the fact that PLWHA are at high risk of dental caries, utilization of dental health service among PLWHA are still low. Objective. This study aims to know the factors influencing dental caries in HIV/AIDS patients.Methods. This is a descriptive, cross-sectional study conducted on 16 HIV-seropositive individuals. They were asked to complete a WHO questionnaire concerning basic oral health and quality of life. Dental caries was assessed using the Decayed, Missing, and Filled Teeth (DMFT) index. Whole stimulated saliva samples were also collected.Results. Nine out of 16 respondents had low salivary flow rate (56.3%). One patient had low DMF-T score (6.3%) and eight had high DMFT score (50%). Among seven respondents who had normal salivary flow rate (43.8%), two of whom had low DMFT score (12.5%) and five of whom had high DMFT score (31.3%).Conclusion. People living with HIV/AIDS have high DMFT and low salivary flow rate.
