A vásárlók az erősödő piac következtében egyre magasabb szintű kiszolgálást várnak el. A kiszállítási idők csökkenése és a termékelérhetőség maximalizálás mellett, a platformok használhatósága, a kiszolgáló személyzet kedvessége, a „fenntarthatóság” megjelenése illetőleg a fizetési lehetőségek kibővítése mintegy alapvető elvárásként jelenik meg. Ennek érdekében az ellátási láncoknak jól szervezettnek kell lennie, amelyhez az információtechnológia hatékonysága elengedhetetlen. Azon kiskereskedelmi láncok melyek „omnichannel” értékesítési formában működnek számtalan versenyelőnnyel rendelkeznek, azonban előfordulnak olyan kihívások is, melyekkel szembe kell nézniük, a több csatorna egyidejű és egy helyen történő üzemeltetése során. A tanulmányban a logisztika és az ellátási lánc folyamatait nézzük át, elsősorban a termékelérhetőséget vizsgáljuk meg egy magyarországi online élelmiszer szolgáltató esetén, hogy milyen kihívásokkal kell szembe nézni annak érdekében, hogy minél magasabb szolgáltatási színvonalat legyen képes biztosítani. Az omnichannel működési formát üzemeltető kiskereskedelmi láncok a több csatorna okán számos kihívással szembesülnek a termékelérhetőség biztosításában, a publikációnkban ezeket azonosítjuk és megoldásokat javaslunk rá.","PeriodicalId":7021,"journal":{"name":"Acta Periodica Technologica","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83835437","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}

Total phenolic and flavonoid contents were determined. HPLC was used to determine the quantity of phenolic compounds in these extracts. The results showed that the antioxidant, antimicrobial and anti-inflammatory activities were higher in the Aqueous Extract (AEC) in comparison with the ethanolic extract of chamomile. The AEC contained chlorogenic acid with a greater amount of other ingredients (2.45 mg/g). This plant had an antioxidant activity with IC50 values equal to 65.199 ?g/ml for AEC and 102.90 ?g/ml for the EEC. The AEC had an antimicrobial activity against Escherichia coli, and Candida albicans with a diameter of inhibition zone equal to 16.33 and 15.66 mm, respectively. Matricaria chamomilla was practically nontoxic with a median lethal dose (LD50) equal to 3800 mg/kg of EEC and superior to 5000 mg/kg of AEC). The Carrageenan method was used in the test of the anti-inflammatory activity which gave the best inhibition of edema, 86.30% at (100 mg/kg) after 6h of induced Carrageenan.","PeriodicalId":7021,"journal":{"name":"Acta Periodica Technologica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68412048","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}

The lipophilicity parameters were calculated using various computational approaches and computer programs. The conducted analysis is the basis for further studies aimed to define, compare and examine the influence of alkyl and cycloalkyl substituents, introduced in 6-chloro-1,3,5-triazine-2,4-diamine structure, on molecular lipophilicity and bioactivity. The chemometric methods used in the study are pattern recognition methods, such as hierarchical cluster analysis (HCA) and sum of ranking differences (SRD). The obtained ranking results indicate that the following in silico lipophilicity descriptors can be chosen as the most suitable for interpretation of lipophilicity of the studied series of s-triazine derivatives: AlogP, MlogP, WLOGP, logPKLOP and logPPHYS. The lipophilicity descriptor iLOGP was marked as the least suitable lipophilicity descriptor of the studied series of compounds. The ranking results were validated by 7-fold cross-validation approach and by comparison of ranks by random numbers (CRRN).","PeriodicalId":7021,"journal":{"name":"Acta Periodica Technologica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68412545","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}

The country’s main strategic goals were becoming a superpower with efficient economy that was able to minimise the object poverty and transform the country into upper-mid class income, economicaly developed region. According to the traditional Chineese maxim: “strong nation is a rich nation”, that used to be regarded as a tool holding the leading position around the world. The investments, realised by the private companies were encouraged in many cases by governmental initiatives as well. China has continually transformed the elements of its innovation strategy and refined them in the global direction of innovation. Despite of the growing literature on Chinese innovation, consensus as to a unique model of Chinese innovation management has yet to emerge. In this context, one of the most crucial but less discussed aspect can be the engagement of the well-educatated, experienced high quality labor work force in China. During the last decades you can observe a significant shifting toward the previous, cheap and huge amount labor workforce corporate attitude toward attracting and managing talents, providing Chineese manner “tailor made” onboarding and personal and professional development of the adequately recruited and selected labor workforce, eliminating the labor turnover but on different way compared to the Western countries methods. This review paper is aiming to reveal the specific features of Chineese-style Human Resource Management (HRM) practice linked with the Chineese traditions and cultural values.","PeriodicalId":7021,"journal":{"name":"Acta Periodica Technologica","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86832521","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}

The best removal percentage (85%) is obtained for a ratio ASAC/TEAS (1/1). Adsorbent characteristics are investigated by the Brunauer-Emmett-Teller (BET), the scanning electron microscope (SEM), infrared spectroscopy (IR), X-ray fluorescence (XRF) and X-ray diffraction (XRD). The impregnation of TEAS and ASAC produces good adsorbent properties towards PNA especially in the ratio (1/1) and an increase in the specific surface. The isotherm data are well fitted by the Langmuir and Freundlich models. The maximum PNA uptake obtained is 94.34 mg g-1. The performances of ASAC/TEAS for the PNA adsorption were compared with some adsorbents previously studied for the same purpose, and results show that the composite in the present work exhibit better performances. The adsorption behavior of the concerned material is explained on the basis of its chemical nature and porous texture.","PeriodicalId":7021,"journal":{"name":"Acta Periodica Technologica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68411896","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}
