Mathematical models based on decision hypergraphs for designing a storage cabinet

We study the problem of designing a cabinet made up of a set of shelves that contain compartments whose contents slide forward on opening. Considering a set of items candidate to be stored in the cabinet over a given time horizon, the problem is to design a set of shelves and a set of compartments on each shelf, and select the items to insert into the compartments. The objective is to maximize the sum of the profits of the selected items. We call our problem the Storage Cabinet Physical Design (SCPD) problem. The SCPD problem combines a two-staged two-dimensional knapsack problem for designing the shelves and compartments with a set of temporal knapsack problems for selecting and assigning items to compartments. We formalize the SCPD problem and formulate it as a maximum cost flow problem in a decision hypergraph with additional linear constraints. To reduce the size of this model, we break symmetries, generalize graph compression techniques and exploit dominance rules for precomputing subproblem solutions. We also present a set of valid inequalities to improve the linear relaxation of the model. We empirically show that solving the arc-flow model with our enhancements outperforms solving a compact mixed integer linear programming formulation of the SCPD problem.

A decentralized solid compound storage facility managed by a centralized electronic platform at a growing drug discovery company

Within a growing drug discovery company, scientists acquire (either through in house synthesis or purchase) then store, retrieve, and ship solid compound samples daily between multiple locations. The efficient management and tracking of this entire process to support drug discovery is a significant challenge. This article describes a decentralized and cost-effective inventory facility that simplifies the solid compound storage and retrieval process. Standardized storage cabinets from the market are utilized, providing a cost-effective physical infrastructure. The cabinets can be distributed across storage rooms at multiple sites and arranged into spaces with a variety of dimensions, allowing the system to be retrofitted into existing facilities and scaled up easily. We can provide storage close to work areas at each location, minimizing both unnecessary movement of staff and transportation of substances. We have applied a systematic barcoding method to the compound batch identifier that correlates with its compound location. This simplifies the compound registration process as well as the process of finding and returning compounds. Additionally, a centralized electronic platform has been employed to store, update and track solid compound information, such as properties, location and quantity. Compound shipment may be initiated from different sites, and a centralized electronic platform assists the information retrieval process, ensuring each location possesses up-to-date information. The electronic platform we present streamlines the management of compound registration, location tracking, weight updates and shipment information, facilitating seamless record sharing among all stakeholders. Every step of the process can be tracked in real time by the project team. The platform can be flexibly configured to adapt to an evolving set of storage locations, with all information and processes being audited.

Efficacy of Essential Oil Vapours in Reducing Postharvest Rots and Effect on the Fruit Mycobiome of Nectarines.

Nectarines can be affected by many diseases, resulting in significant production losses. Natural products, such as essential oils (EOs), are promising alternatives to pesticides to control storage rots. This work aimed to test the efficacy of biofumigation with EOs in the control of nectarine postharvest diseases while also evaluating the effect on the quality parameters (firmness, total soluble solids, and titratable acidity) and on the fruit fungal microbiome. Basil, fennel, lemon, oregano, and thyme EOs were first tested in vitro at 0.1, 0.5, and 1.0% concentrations to evaluate their inhibition activity against Monilinia fructicola. Subsequently, an in vivo screening trial was performed by treating nectarines inoculated with M. fructicola, with the five EOs at 2.0% concentration by biofumigation, performed using slow-release diffusers placed inside the storage cabinets. Fennel, lemon, and basil EOs were the most effective after storage and were selected to be tested in efficacy trials using naturally infected nectarines. After 28 days of storage, all treatments showed a significant rot reduction compared to the untreated control. Additionally, no evident phytotoxic effects were observed on the treated fruits. EO vapors did not affect the overall quality of the fruits but showed a positive effect in reducing firmness loss. Metabarcoding analysis showed a significant impact of tissue, treatment, and sampling time on the fruit microbiome composition. Treatments were able to reduce the abundance of Monilinia spp., but basil EO favored a significant increase in Penicillium spp. Moreover, the abundance of other fungal genera was found to be modified.

Implementation of the 5S work culture (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) in the engineering department of PT X, Sidoarjo

Work culture is closely related to the norms, beliefs, values, and attitudes formed in a company. One of the important work cultures owned by the company is the 5S culture or housekeeping whose application needs to be done as a form of self-protection of workers to stay safe in carrying out work activities so as to increase company productivity. PT X is one of the companies in Sidoarjo engaged in animal feed. The purpose of this study is to analyze in depth the implementation of the 5S work culture (Seiri, Seiton, Seiso, Seiketsu, and Shitsuke) in the Engineering Section of PT X, Sidoarjo. This research is a qualitative study with a descriptive approach, namely by providing a description of the actual conditions related to the implementation of 5S in the company. Data collection techniques are carried out by means of observation, interviews, and documentation studies. Based on the results of the study, the 5S work culture at PT X Engineering Section is still not optimally implemented. This is evident from the condition of the workplace that has not been well maintained, many unused items are in the workplace, and there are storage cabinets that are not labeled with information. The lack of awareness of workers regarding 3S habituation and the lack of supervision from management are inhibiting factors in implementing 5S optimally.

Improvement of heating and cooling performance for thermoelectric devices in medical storage application

Thermoelectric devices provide several advantages over typical refrigeration systems, including compact size, quiet operation, minimal energy use, and environmentally friendly. By harnessing these benefits, we have developed a blood storage system that has the potential to transform the way blood products are preserved and safeguarded. Thermal performance was evaluated using a variety of scenarios, including thermal fin material and emissivity, voltage operation, heat sink type (I, U, O type), and tube load. This research used thermoelectric devices, Styrofoam materials, thermal fin and the heatsink to design the thermoelectric storage cabinet with heat insulation function. The aims to improve the performance of thermoelectric devices by optimizing the thermal fin design during heating/cooling storage mechanisms. Our findings emphasize the importance of thermal radiation, particularly in circumstances with low natural convection and high surface emissivity. Thermal performance is optimized when heating storage elements are incorporated into aluminum finned tubes and run at an input voltage of 8V in a 25 °C ambient temperature. In addition, using U-shaped cooling fins in cooling conditions results in superior cooling performance. The outcomes of this study highlight the possibility and potential benefits of using thermoelectric devices to heat and cool medical storage, notably blood storage applications. The insights gained here contribute to advancing the efficiency and sustainability of medical storage systems, ultimately benefiting healthcare and the environment.

Information System for Collecting Customer Collateral Using PHP and MySQL (Case Study BPR BKK, Giritontro, Wonogiri Branch)

Rural Credit Bank of Giritontro District (BPR BKK Giritontro) is a financial institution engaged in savings and loans in the Giritontro District of Wonogiri. BPR BKK's customers provide collateral when applying for loans, and once the loans are repaid, the collateral is returned. However, the current collateral retrieval process at BPR BKK Giritontro is done manually through recording in a logbook maintained by administrative staff, leading to issues such as vulnerable and easily lost storage media. Additionally, there can be delays in the retrieval process if the administrative staff is absent, as only they have access to the storage cabinet key. The logbook system also hinders data search efficiency for collateral retrieval verification. This research aims to develop an information system for customer collateral retrieval to assist the administrative department in managing collateral retrieval. The author adopts the System Development Life Cycle (SDLC) waterfall model for system development and utilizes PHP programming language and MySQL database for the information system implementation.

Experimental investigation on thermal performance of self-service cold storage cabinet based on the orthogonal test

Self-service cold storage cabinets (SCSCs) are widely used in the delivery end of cold chain logistics for fresh agricultural products, to maintain the freshness of the products in a low temperature environment. Based on the three-factor and four-level orthogonal test, this paper first analyzed the impact of pure geometric structure factors on the thermal performance of SCSC. The priority of the geometric structure factors of the SCSC on the thermal performance is determined by means of four evaluation metrics. Then, two operating factors including air supply velocity and temperature are added to the consideration, and a five-factor and four-level orthogonal test is conducted based on the aforementioned five factors. The priority and optimal level of various factors were determined based on the test results. By comparing the results of two sets of orthogonal tests, it is found that the optimal level of the structure is affected by the change of air supply conditions. After optimizing the SCSC, the temperature range, temperature inhomogeneity coefficient, and velocity inhomogeneity coefficient decreased by 1.316 ℃, 21.16%, and 2.18% respectively, while the average temperature increased by 2.028 ℃, and the power consumption decreased by 4.81% compared to the original level of factors (test plan 1).

SISTEM KEAMANAN LEMARI PENYIMPANAN BARANG MENGGUNAKAN PASSWORD SEBAGAI KENDALI AKSES DAN SENSOR ULTRASONIK SEBAGAI PENDETEKSI BARANG

A sense of security in storing items and ease of finding storage cabinets in public places such as shopping centers is absolutely necessary, but this may still not be fulfilled because storage cabinets still use conventional locks or still use cards to store items, plus it requires a time-consuming process to look for an empty storage cabinets. Therefore, the creation of a storage cabinets model in this research aims to implement a security system for a storage cabinets with access control using a password and to know whether there are items in the storage cabinets or not so that users can find out which storage cabinets are available/empty. This storage cabinets security device uses a solenoid as a lock, a servo motor to actuate the cabinets door, an ultrasonic sensor to detect items in the cabinets and control it via keypad and LCD to display the condition of the cabinets use. This tool uses an Arduino Mega microcontroller as the main controller and password storage medium, thereby producing output automatically where the solenoid will open/close and the servo motor moves to open/close the cabinets door. The tool can function to detect items in cabinets and based on item detection using an ultrasonic sensor the user can find out which cabinets are empty and the cabinets door will open based on a password determined by each user to ensure the security of the items stored.

Transcribing the Sacred in the Printing Era: A Study of Handwritten Buddhist Canon during the Northern Song Dynasty

In an era marked by the advent of advanced printing technology during the Northern Song period, the tradition of transcribing the Buddhist canon endured rather than promptly fading away. This persistence is particularly noteworthy in the 10th to early 12th centuries when handwritten copies of the canon coexisted with the emerging prevalence of block-printed versions. Notably, the monasteries in the Jiangnan 江南 region remained prolific producers of handwritten copies. This article adopts a socio-political perspective to elucidate the coexistence of handwritten and block-printed copies. It delves into the dynamics of canon replication within a specific temporal and geographical context, unveiling a broader tableau of handwritten copies in the printing era. This exploration necessitates an examination of the intricate interplay between the state, the canon, and Jiangnan society. This study contends that the state’s printing policies before the Xining 熙寧 period (1068–1077), which rigorously regulated the production and dissemination of canonical texts, constituted a pivotal factor in sustaining the tradition of handwritten copies. Furthermore, it identifies a sustained societal demand for possessing the canon for constructing the zhuanlun zang 轉輪藏 (revolving wheel storage cabinet), which was most pronounced in the Jiangnan region. This persistent societal need fortified the enthusiasm for transcribing the canon within Jiangnan monastic communities.

The Analysis Of Blood Supply Chain Performance Based On Supply Chain Operation Reference Model And Causal Loop Diagram Approach

This study evaluates the effectiveness of the blood supply chain and determines potential causes of substandard supply chain performance. Unfulfilled demand for blood at UDD PMI Indragiri Hilir in 2021 reached 970 bags, or 14.1% of all orders. The method used is SCOR (supply chain operation references) and CLD (cause loop diagram). The novelty of this research is applying the SCOR model to holistically measure the blood supply chain's performance and determine the leading causes of low performance. The total value of supply chain performance is 77.78, which is a good category. The results show that Five matrices fall into the low-performance process on the Production attribute (28.24), Capacity Utilization Screening (37.50), Capacity Utilization of Blood Quarantine Storage Cabinets (39.01), Capacity Utilization of Healthy Blood (44.44), and Capacity Utilization Crossmatch (33.3). Based on CLD analysis, potential root causes of the low performance of the supply chain with the CLD model are five low-performance matrices on production attributes influenced by voluntary donors and replacement donors, the number of donors, and blood tapping.

Evaluation model for modular children's wooden storage cabinet design

The design evaluation method of furniture products was explored for modular children’s wooden storage cabinets. An evaluation model consisting of the Kano model, hierarchical analysis, and grey relational analysis is proposed. A 25-member panel of experts was involved in the development of the evaluation guidelines and the scoring of the program. The expert group used the KJ method to obtain evaluation guidelines for modular children’s wooden furniture that met the requirements of the hierarchical analysis method and screened the functional indicators through 103 validated questionnaires for the Kano model. The evaluation guidelines of modularized children’s wooden storage cabinets were thus obtained, which are both comprehensive and targeted. Then, hierarchical analysis and grey relational analysis were combined to select the solution with the highest grey weighted correlation result as the best solution. The feasibility of the grey comprehensive evaluation method, which combines subjective preference and objective empowerment, in the field of furniture was confirmed through the practice of selecting the best of the three modular children’s wooden storage cabinet design solutions, and the evaluation preference of the modular children’s wooden storage cabinet was uncovered. The design model provides an innovative evaluation tool for children’s furniture manufacturers to optimize their sales strategies.

Iatrogenic Injury During Intraoperative Transesophageal Echocardiography: Implications for Medical Equipment Storage.

Medical equipment failure is an underappreciated source of iatrogenesis. The authors report a successful root cause analysis and action (RCA2) to improve compliance and decrease risks to patients during cardiac anesthesia care. A quality and safety team of five content experts performed an RCA2 after an iatrogenic injury with transesophageal echocardiogram (TEE) probe insertion. The team used a fishbone diagram to identify causes and performed a Gemba walk to discuss probability of the different causes with key stakeholders. The team reviewed hospital policies and procedures as well as manufacturer manuals regarding best practices for maintenance and storage of TEE probes. The team created a corrective action plan centered on purchasing larger TEE storage cabinets, education of those who handle TEE probes, and implementing standard operating procedures. Effectiveness of the intervention was evaluated by analyzing frequency of TEE probe maintenance. The study period ranged from July 2016 to June 2021. TEE probes required maintenance 51 times, of which 40 (78.4%) occurred prior to the larger storage cabinet purchase, and 11 (21.6%) afterward. The number of TEE probes requiring maintenance per quarter was 4.4 (standard deviation [SD] 2.5) during the preintervention period and 1.0 (SD 1.0) during the postintervention period (mean difference 3.4, 95% confidence interval 1.0-5.9, p = 0.0006). An extensive RCA2 resulting in a corrective action plan centered on compliance with manufacturer recommendations for storage of TEE probes resulted in fewer maintenance requests, which decreased the risk of iatrogenic patient injury from TEE probe failure during cardiac anesthesia care.
