In supply chain management, the employed forecasting algorithm plays a very vital and crucial role in how a particular business performs well in the market. This study proposes a time series based forecasting model to help in designing an effective make-to-stock supply chain mechanism for tackling the large number of suppliers (suppliers diversion) and products (items diversion). The proposed technique extends the traditional ARIMA model to ARIMA Double Layering Technique (DLT) where the algorithm is implemented in two layers: first one is to obtain the number of orders level, and the other layer is implemented at the quantity level. The systematic implementation procedure of our approach is illustrated through a real case study. The accuracy evaluation and consistency of the results show that ARIMA -DLT provides superior forecasting when compared with ML-based models which provides insightful managerial views to other similar forecasting problems.

A series of all novels 4(3-(4-Fluorophenyl)2-methyl-1-(4-(sulfonamidesubtituted)phenyl)-4-oxoazitidin-2-yl)-3-methyl-1-(p-tolyl)-1H-pyrazol-5(4H) One 5a-5r poly functionalized derivatives were containing sulfonamide functionality united with 2-Azitidinone (Azitidin-2-one or β-lactam) group which designed and synthesized with moderate to good yield. The starting with 4-acyl-2-pyrazolin-5-one (APYZ) 1 which condensed with different sulfonamides 2 produced intermediate Schiff bases 4-(arylideneamino)-N-(thiazol-2-yl)benzensulfonamide 3a-r were cyclization with 2-(4-flourophenyl)chloroacetylchloride (F-CAC) 4 which produced targeted compounds 5a-5r of 2-Azitidinone versatile group in good yield. The isolated compounds were recognized by spectral and elemental investigation. The compounds 5f, 5l, 5n, and 5r showed excellent increased antibacterial activity compared to streptomycin standard drug and 5c, 5f, 5l, 5o, and 5r showed moderate to good antioxidant properties with used DPPH radical scavenging assay.

The main problems found mainly in the ferry transportation in the port of Merak-Bakauhuni in the Province of Banten, Indonesia, is the high occupational accident due to safety procedures and low ship crew competency which finally influence the company's operational performance. The aim of this research was to know and analyze the influence of safety procedures and ship crew competency on passenger safety that has impacts on the company's operational performance of ferriage at the port. This research used Structural Equation Model – SmartPLS4 with a research sample of as many as 150 ship crew. The results of this research indicated that safety procedures and ship crew competency positively and significantly influence passenger safety. Besides, safety procedures, ship crew competency, and passenger safety positively and significantly influence operational performance. These results also confirmed that passenger safety could mediate the influence of safety procedures on operational performance and the influence of ship crew competency on operational performance.

This work presents a comprehensive synthesis method for the development of a new hyperbranched unsaturated polyester resin (HUPR). The resin is synthesized by modifying dehydrated castor oil fatty acid (DCOFA) with methyl methacrylate (MMA) and styrene, dicyclopentadiene-maleate (DCPD-M), and trimethylol propane diallyl ether (TMPDE). The synthesis process involves the radical addition reaction of DCOFA with MMA and styrene, followed by the addition of DCPD-M and TMPDE to form a HUPR. The resulting resin exhibits enhanced properties, making it a promising candidate for car body putty in the polymer industry.

Supply chain plays a very important role in the socio-economic development of countries, especially in the context of the fourth industrial revolution associated with the development of the sharing economy as well as associated with the rational and optimal allocation of resources. Studying the impact of supply chain management on the development of the sharing economy in the case of Hanoi, Vietnam and using advanced quantitative analysis methods, the research results show that perfecting the supply chain helps businesses rationalize costs and thus can improve business performance and promote the sharing economy. The study also shows that the quality of human capital and technological level have a positive impact on the sharing economy. Therefore, when the economy increases the contribution of technology to production activities, it helps businesses increase their choice of the sharing economy and thus helps to allocate resources more effectively and optimally.

Vietnam is a rapidly developing country associated with changes in socio-economic activities, especially both public and private services. The service industry is making a practical contribution to economic growth and is gaining a great position. To help a society develop harmoniously, the economy must satisfy people's ability to access services, especially basic services such as education, healthcare, legality, transportation, security and safety. The aims of the study are to estimate factors affecting legal service quality, and based on the survey in three provinces in Vietnam: Lam Dong, Dak Lak, Gia Lai and through quantitative analysis, the research results show that there are five factors that positively affect service quality, which are: (1) government; (2) head of the unit; ⁠(3) influencer; (4) opinions of people around; and (5) organizations and individuals providing services. The research results also discuss some solutions to increase service quality and sustainable development of Vietnam in the coming time.

The purpose of the study is to determine how supply chain flexibility (SCF), supply chain governance (SCG), and green supply chain practices (GSCPs) affect supply chain performance (SCP). In addition to exploring whether TQM moderates the effect of SCF, SCG, GSCPs on SCP of Saudi medium-sized industrial firms. To this end, data was gathered from 312 employees in Saudi medium-sized industrial firms and analyzed using structural equation modeling (SEM) via Smart PLS 4 software. The study revealed that GSCPs and SCG have a positive, significant and direct effect on SCP, in addition to that SCF and TQM do not have a direct positive effect on SCP. The study also found that TQM modifies the relationship between GSCPs, SCF, SCG and SCP.

New analogues of pulmonarin B were synthesized from (3,5-dibromo-4-hydroxyphenyl)acetic acid derivatives, and their antibacterial and antibiofilm activities against E. coli, S. aureus, and P. aeruginosa were evaluated. The antibacterial activity of synthesized ammonium salts against the methicillin-resistant strain of S. aureus 222 depends on the length of the alkyl chain. Bisquaternary ammonium salt 5 demonstrated better activity against S. aureus 222, E. coli 311, and P. aeruginosa 449 compared to mono-alkylated derivatives. Analogues of pulmonarin B 5 and 4d reduced S. aureus 222 biofilm formation by 74.5% and 89.4%, respectively. In addition,
compound 4c turned out to be the most active against the biofilm formation of P. aeruginosa 449 (biomass decreased by 39.8%).

Future global economic stability is under significant threat from environmental risks. Rural peat areas are particularly susceptible due to their elevated levels of hazard, vulnerability, and limited capacity. Acknowledging these risks is pivotal for fostering a low-carbon development trajectory. This study analyzes the environmental risk in rural peat areas within Riau Province. The PROMETHEE method, incorporating Shannon Entropy weighting for data analysis, was employed. The findings reveal that four regencies are exhibiting favorable environmental risk conditions and five regencies facing adverse conditions. The criteria influencing the environmental risk of rural peat in Riau Province showcase various positive and negative contributions across each regency. The sensitivity analysis underscores the resilience of forest fires and the social forest program in three regencies. Recognizing environmental risk can serve as a foundation for decision-makers to formulate sustainable development policies.

One significant and elegant method for creating β-amino alcohols, which are useful intermediates for the synthesis of many different natural and synthetic pharmaceutical compounds, is to open the rings of epoxides with amines. When sulfated tin oxide catalyst (2 mol%) is present, epoxides can open their rings and react with amines to produce corresponding β-amino alcohols in good to high yields under mild circumstances. Under clean circumstances and in a short amount of time, the reaction demonstrated high regioselectivity and functioned well with both aromatic and aliphatic amines at room temperature.
