Earticle

When an induced voltage by an aerial power distribution line is calculated, there would happen a very large error according to the position of induced section because the current calculation method described in the national specification does not reflect the effect of leakage current through the each pole ground and uses just a predetermined value for a shielding effect of neutral line. The methodology of this paper is based on the splitted formulae for a calculation of neutral line shielding effect with the accumulated earth return current of leakages on each pole. And it has introduced the integration concept to equalize various terminal line distance as an one same distance utilizing a factorized composition form of leakage current rate against total unbalance current flowing in a neutral line at the start point of induced section. This method enhanced an efficiency of calculation which results into an increase of accurate rate as 93 % than the one of existing method, compared to real measured values.

This research introduces an innovative approach in implementing Know Your Customer (KYC) on blockchain technology as a means of using data, hybrid robust m-estimation, and the iteratively reweighted less squares (IRLS) method to optimize CLV data. This approach aims to improve the accuracy and reliability of CLV predictions by ensuring the security and reliability of customer data. This tool can help companies manage and increase CLV more effectively, meeting data security and compliance standards. The R-squared validation test results are close to 1, so the model can explain data variations well. RMSE and MSE have small values, ??so the model has good performance in predicting the target value. With these achievements, this approach contributes to the development of better marketing strategies and business decisions in an increasingly complex and rapidly changing digital environment.

Canine induced Pluripotent Stem Cells (iPSCs) can provide great potential for regenerative veterinary medicine and may assist in the development of new therapeutics and pre-clinical studies for both dogs and human. To date, there have been several reports on the generation of canine iPSCs using retroviral or lentiviral transduction of Yamanaka’s factors. However, there is no report of canine iPSCs generated by genomic integration-free methods. According to previous studies, a polycistronic and synthetic self-replicating RNA system was developed for generating human iPSCs by the RNA replicon of Venezuelan Equine Encephalitis (VEE) virus. The VEE replicon is a positive-sense and single-stranded RNA which is similar with cellular mRNA containing a 5’ cap and poly (A) tail. It is no potential for genomic DNA integration problems because it does not use a DNA intermediate. Here, we investigated to generate canine iPSCs by a single transfection of the VEE-reprogramming factor (VEE-RF) RNA. To generate integration- free canine iPSCs, the VEE-OKS-iG RNA that expresses four reprogramming ORFs (hOct4, hKlf4, hSox2 and hGlis1) was transfected. Also, B18R mRNA was co-transfected to reduce immune response by VEE replicon. Putative canine iPSC colonies first appeared between day 15-25. Interestingly, they have two distinct types of initial canine iPSC colonies. They were identified by immunohistochemistry of live cells using TRA-1-60 antibody and also showed clear alkaline phosphatase (AP) activity. Further study will be required to analyze the characterization for a clinical application, and the non-integrating and self-replicating VEE RNA replicon system has the potential to make a great contribution to generating clinically applicable canine iPSCs.

Robots equipped with artificial intelligence technology include learning functions. Purely inductive learning methods formulate general hypotheses by finding empirical regularities over the trainning examples. Purely analytical methods use prior knowledge to derive general hypotheses deductively. Therefore, when the physical environment of a robot is complex, there is a problem of increased computational time required for information processing. In particular, when a large number of robots transmit information, more computational time is required for information processing. The distance-based topological method proposed in this paper first constructs the topology based on the distances between robots, and then generates information weights according to the stages of the topology. The technique proposed in this paper has been experimentally confirmed to have excellent performance in environments with a large number of robots and complex physical conditions.

Purpose: Through recent improvements to the national contract system, safety evaluation has been mandated across public construction projects. However, the current evaluation framework is limited to legal compliance checks and formal document reviews, which restricts its effectiveness in practical disaster response and construction continuity. This study aims to propose an integration model between the National Contract System safety evaluation and the Business Continuity Management System (BCMS) based on ISO 22301. Method: This study conducted a literature review and case analysis to identify limitations of the existing safety evaluation system. Core BCMS elements—risk assessment (RA), business impact analysis (BIA), recovery strategies, and training and exercise systems—were analyzed and mapped to safety evaluation items to develop an integrated evaluation framework. Result: The results indicate that incorporating BCMS elements into the national contract system safety evaluation enables a shift from a compliance-oriented assessment to a comprehensive evaluation system that strengthens disaster response and recovery capabilities in construction projects. Conclusion: The proposed integration model enhances construction safety management by improving continuity and resilience beyond legal compliance. The findings can serve as foundational data for institutional improvement and practical application, including future revisions to the Enforcement Decree of the Special Act on Construction Safety and the National Contract Act.

Objective : This study presents guidelines for setting up a sensory integration room by applying the Delphi method. Methods : The Delphi method was applied in a survey of 22 expert panels asked to review sensory integration therapy from May to June 2020 to collect expert opinions. The survey was conducted in two rounds. The first round involved the collection of opinions based on prior research that used a total of 40 assessment tools, 23 closed questions about treatment tools, and 10 questions about the physical environment. Based on the results of the first round, the second was conducted using a process of item deletion and modification. Results : A total of 59 items were selected in the first round of the survey. In the second the contents of these 59 items were analyzed: each item scored .42 or higher, so no items were deleted. The stability of the survey was also calculated and found to be less than 0.5, so no further testing was required. The average content feasibility ratio of the final Delphi survey was .92, stability .15, convergence .36, and consensus .80, showing high agreement. Conclusion : This study is expected to help institutions and clinical therapists who want to create a sensory integration therapy room in their facilities by examining the physical environment, treatment tools, and evaluation tools used in sensory integration therapy rooms and understanding the views on such environments obtained from the clinical site to sensory integration therapists.

Indoor evacuation model can provide scientific guidance for security solution design and emergency plan making in indoor environment, and virtual 3D scene can make the evacuation simulation more intuitive. An integration method of multi-grid evacuation model in 3D virtual indoor environment is proposed here. It maps 3D scene to 2D plane and establishes the grid table first, and then for each grid, calculates the shortest distance to accessible exits. After that, using the route selection method of multi-grid model to calculate the target position for each pedestrian in one time-step and matching the position to 3D scene, and invoking the action library to simulate the movement. Besides, the effect of ground slope is taken into account on pedestrian velocity. Experiment shows that the method is feasible and effective.

In recent conflicts, such as those in Ukraine and the Middle East, the critical importance of advanced combined air-defense missile systems for combat effectiveness has become increasingly apparent. These integrated systems are tasked not only to detect and engage a spectrum of enemy threats but also to adapt swiftly and reliably to dynamic, rapidly changing circumstances, especially after missile launch. To verify advanced combined air-defense missile system's functionality after missile launch, it is ideal to conduct comprehensive system tests using various scenarios and actual flight tests. However, due to limitations such as high cost and lengthy setup time, this approach is often difficult to implement in reality. In the past, system verification after missile launch has mainly relied on component-level inspections and HILS tests. While these methods can partially check individual system functions, they are not sufficient to fully verify all system functions as a whole. This paper proposes a system integration test method that uses a system integration simulator capable of simulating various combat scenarios and a missile beacon equipped with a missile flight model. Missile flight model uses the same algorithm as the guidance control method employed in actual missiles. Through the adoption of the proposed system integration test method, it was confirmed that a majority of previously limited and difficult-to-verify missile engagement-related test items can now be comprehensively validated. Furthermore, this method allows for comprehensive verification of the system's performance after missile launch, including its interoperability and response capability from a systemic perspective. It also contributes to increasing the reliability of the combined air-defense missile systems.
