An exact algorithm is presented for a parallel machine scheduling problem with additional resources constraints. Specifically, the jobs need be processed on parallel machines, and the processing of each job requires a unit of some additional resources in addition to machine resource. The variety and amount of additional resources are limited, our goal is to make the optimal schedule of the problem so that the completion time of the final completed job is minimized. This problem originates from the field of earth observation satellite data download, and has been widely used in intelligent manufacturing and information processing. The integer programming model, the lower bound of the optimal solution and the branch and bound algorithm of the problem are given. An effective branching strategy is proposed to avoid repeated branching and a bound method is designed to improve the convergence rate of the algorithm. The correctness and the effectiveness of the algorithm under different parameter configuration are verified by a large number of numerical simulation experiments and a small-sized instance example.(给出了一类加工需要额外资源的平行机调度问题的精确算法。针对在平行机上加工的工件，除需要机器资源外，还需要一个单位额外资源的问题，考虑额外资源的种类和数量有限，以给出问题的最优调度使工件的完工时间最小为目标。该问题源于地球观测卫星的数据下载，在智能制造和信息处理等领域亦有广泛应用。给出了该问题的整数规划模型、最优解下界和分支定界算法；给出了一种有效的分支策略以避免重复分支，设计了相应的定界方法以提高算法的收敛速度。通过小规模实例和大量的数值仿真实验，验证了算法的正确性和在不同参数配置下的有效性。)

Objective To provide reference for clinical pharmacists in neonatology to participate in clinical pharmacy and to promote the standardized clinical use of Meropenem through the analysis of the intervention of clinical pharmacists on the use of Meropenem in neonatology in a tertiary care women's and children's specialty hospital. Methods Retrospective analysis of 123 medical records of all Meropenem use in the neonatology department of the hospital in the six months(January-June 2017) before the clinical pharmacist did not participate in the clinical checkup of the department(pre-intervention group), and 70 medical records of all Meropenem use after the participation(January-June 2020) in the checkup of the department for medication intervention (post-intervention group). The study compared Meropenem before and after the clinical pharmacist intervention in the neonatal unit in terms of indications, dosage and dosing, pathogenetic and efficacy assessment, and co-administration of Meropenem. Results After the intervention, all the medical records of Meropenem in the post-intervention group were significantly improved in terms of indications, dosage, timing of step-downs, and combinations compared with those of the pre-intervention group, and the differences were statistically significant (P <0. 05). Conclusion The deep involvement of clinical pharmacists in the neonatal department in clinical work for medication intervention plays a greater role in promoting the standardized use and continuous improvement of carbapenem antimicrobials.

Considering that the problems of low efficiency and credibility in traditional honey traceability, this study constructed a solution that combines blockchain technology and InterPlanetary File System technology to establish a highly reliable honey traceability system after analyzing the honey traceability standards. Firstly, this study introduced a hierarchical storage strategy to enhance the efficiency of on-chain information and traceability; Subsequently, this approach employs a multi-chain architecture to isolate data. It utilizes a proxy re-encryption scheme based on external random oracles, whereby ciphertext re-encryption is executed through smart contracts. Simultaneously, message authentication codes are integrated to effectively address challenges such as low information credibility, forgery, and potential privacy data leaks. Lastly, this paper proposed a pre-commit mechanism to prevent inconsistencies in data caused by sudden loads, that is, the scheme of "high-traffic package pre-commit, low-traffic supplementary on-chain".To assess the feasibility of the proposed solution, simulations and tests were conducted using Apache Bench tools. The results demonstrate that the scheme effectively achieves the chaining of basic data, controllable supervision, and credible traceability. Furthermore, it fulfills the multi-level requirements of enterprises, regulatory authorities, and users. [ABSTRACT FROM AUTHOR]
