The similarity of the software is extracted by the verification of comparing with the source code. The source code is the intellectual copyright of the developer written in the programming language. And the source code written in text format contains the contents of the developer's expertise and ideas. The verification for judging the illegal use of software copyright is performed by comparing the structure and contents of files with the source code of the original and the illegal copy. However, there is hard to do the one-to-one comparison in practice. Cause the suspected source code do not submitted Intentionally or unconsciously. It is now increasing practically. In this case, the comparative evaluation with execution code should be performed, and indirect methods such as reverse assembling method, reverse engineering technique, and sequence analysis of function execution are applied. In this paper, we analyzed the effectiveness of indirect comparison results by practical evaluation . It also proposes a method to utilize to the system and executable code files as a verification results.

Public officials are volunteers for the people, and the police are in charge of the safety of the people. In particular, the marine safety of Korea, which has three sides of the sea, is very important. The education of maritime police is a very important factor due to the specificity and risk of the sea. In particular, since the new curriculum is linked to the job while in office, factors related to educational performance are more important. In this study, the relationship between personality characteristics and academic burnout was examined for 200 new maritime police officials. Among the five factors of personality characteristics, extroversion factors, neurotic factors, and emotional exhaustion factors were extroversion factors, neurotic factors, and cynicism factors, and extroversion factors, neurotic factors, and integrity factors. In particular, the five factors of personality characteristics that have the greatest influence on academic burnout were neurotic.

PURPOSE: This study sought to investigate the change in the satisfaction levels of healthcare students regarding clinical practice before and after the coronavirus disease 19 (COVID-19) outbreak. METHODS: This was a longitudinal survey using a structured questionnaire. The first survey was conducted before the COVID-19 outbreak in April 2018, and the second survey was conducted after the outbreak from May to June 2022. The questionnaire used before and after COVID-19 had the same content and was categorized into the following six factors to determine clinical practice satisfaction: practice guidance, practice environment, practice time, practice evaluation, interpersonal relationships, and effectiveness of practice. Before the COVID-19 pandemic, a total of 153 healthcare students (average age: 22.43 ± 1.47 years old), participated from 4 departments: nursing, physical therapy, occupational therapy, and dental hygiene. After COVID-19, 84 students (average age: 22.75 ± 2.87 years old), from the physical therapy, occupational therapy, nursing, and dental hygiene departments participated in the survey. RESULTS: Clinical practice satisfaction was evaluated considering the factors of practical guidance, practice environment, practice time, interpersonal relationships, and practical effects. It was observed that the satisfaction with clinical practice increased in nursing, physical therapy, occupational therapy, and dental hygiene students after COVID-19 compared to the situation before the outbreak. There was no difference seen in the practice time and practice evaluation factors in the occupational therapy department and in the practice time factor in the dental hygiene department before and after COVID. CONCLUSION: In clinical practice under the extremely constrained circumstances imposed by the COVID-19 pandemic, it seems that the emotional internal response is greater, and the satisfaction with clinical practice appears to be relatively higher than before the outbreak.

This paper presents an analytical hyperbolic theory based on the refined shear deformation theory for mechanical stability analysis of the simply supported advanced composites plates (exponentially, sigmoidal and power-law graded) under triangular, trapezoidal and uniform uniaxial and biaxial loading. The developed model ensures the boundary condition of the zero transverse stresses at the top and bottom surfaces without using the correction factor as first order shear deformation theory. The mathematical formulation of displacement contains only four unknowns in which the transverse deflection is divided to shear and bending components. The current study includes the effect of the geometric imperfection of the material. The modeling of the micro-void presence in the structure is based on the both true and apparent density formulas in which the porosity will be dense in the mid-plane and zero in the upper and lower surfaces (free surface) according to a logarithmic function. The analytical solutions of the uniaxial and biaxial critical buckling load are determined by solving the differential equilibrium equations of the system with the help of the Navier's method. The correctness and the effectiveness of the proposed HyRPT is confirmed by comparing the results with those found in the open literature which shows the high performance of this model to predict the stability characteristics of the FG structures employed in various fields. Several parametric analyses are performed to extract the most influenced parameters on the mechanical stability of this type of advanced composites plates.

Objective: Internal injuries and consumptive disease have different causes, yet they can affect each other. The relationship and combination of prescription drugs in the clinical practice of internal injuries and consumptive disease were analyzed for various diseases of "Donguibogam" through network analysis. Methods: The prescriptions used in consumptive disease and internal injury were established by conducting a full survey on the papers extracted from Donguibogam. The R version 4.0.3 (2020-10-10) and the igraph and arules package were used to perform network analysis and association rule relationship mining analysis in the first and second prescription compositions. Results: The herb frequently used for internal injury was Glycyrrhizae Radix, while the herb combination frequently used was Citri Pericarpium-Glycyrrhizae Radix. For centrality, the main factor was generally Glycyrrhizae Radix. In the case of consumptive disease, the herb most frequently used was Angelicae Gigantis Radix, and the combination most frequently used was Rehmanniae Radix Preparata-Angelicae Gigantis Radix. In terms of centrality, it was Angelicae Gigantis Radix. As a result of the network analysis of herbal prescription frequency, each group was divided into three. Conclusion: The interrelationship between internal injury and consumptive disease prescription drugs may reveal the differences and similarities between internal injury and consumptive disease and may serve as a basis for the development of new drugs or materials that can enhance mutual effectiveness in the treatment of internal injury and consumptive diseases.

Purpose: The purpose of this study was to identify the factors affecting readmission in stroke patients. Methods: A retrospective study design was used. Participants were 3,675 adult cerebral stroke patients in the inpatient wards of the Department of Neurology and Neurosurgery of G University Hospital located in C city. Data were collected from January 1, 2016 to December 31, 2021 and data were analyzed using χ² test, independent t-test, and multivariate logistic regression with SPSS/WIN 24.0. Results: After discharge for stroke, the readmission rate was 23.7%, and the mortality rate was 0.3%. The variables with significant differences between the readmission group and non-readmission group were age, type of stroke, surgery, ICU treatment, mRS score, blood pressure, diabetes, and heart disease. Factors influencing an readmission in stroke patients were Age 65-74 (OR 1.30, 95% CI=1.03-1.64), ≥ 75 (OR 1.28, 95% CI=1.02-1.62), mRS score 2points (OR 2.50, 95% CI=1.99-3.13), HTN status (OR 1.26, 95% CI=1.07-1.50), CVD status (OR 1.38, 95% CI=1.01-1.90), TC (OR 1.60, 95% CI=1.05-2.44). Conclusion: To lower the readmission rate of stroke patients, it is essential to control lifestyle, including whether or not to take treatment drugs, after diagnosing risk factors such as high blood pressure, diabetes, and heart disease, hyperlipidemia. Nursing interventions that can provide information on risk factor management and coping strategies are urgently needed as symptoms change. In addition, research is needed to develop and implement an intervention strategy that can improve the function of stroke patients as much as possible at home or in society so that they can lead an independent life without the help of others, and verify their effectiveness.

This paper presents a vibration displacement measurement and damage identification method for a space truss structure from its vibration videos. Features from Accelerated Segment Test (FAST) algorithm is combined with adaptive threshold strategy to detect the feature points of high quality within the Region of Interest (ROI), around each node of the truss structure. Then these points are tracked by Kanade-Lucas-Tomasi (KLT) algorithm along the video frame sequences to obtain the vibration displacement time histories. For some cases with the image plane not parallel to the truss structural plane, the scale factors cannot be applied directly. Therefore, these videos are processed with homography transformation. After scale factor adaptation, tracking results are expressed in physical units and compared with ground truth data. The main operational frequencies and the corresponding mode shapes are identified by using Subspace Stochastic Identification (SSI) from the obtained vibration displacement responses and compared with ground truth data. Structural damages are quantified by elemental stiffness reductions. A Bayesian inference-based objective function is constructed based on natural frequencies to identify the damage by model updating. The Success-History based Adaptive Differential Evolution with Linear Population Size Reduction (L-SHADE) is applied to minimise the objective function by tuning the damage parameter of each element. The locations and severities of damage in each case are then identified. The accuracy and effectiveness are verified by comparison of the identified results with the ground truth data.

Objectives : Alcohol-induced liver disease advances as to reactive oxygen species (ROS) and cellular lipid peroxidation increase. We examined the hepatoprotective effects of Zingiber officinale Roscoe rhizome extract (ZR), Pueraria lobata Ohwi flower extracts (PF), and a newly developed herbal juice (HJ), which was a combination of ZR and PF extracts, against ethanol-induced hepatotoxicity. Methods: The study utilized the human hepatoma cell line HepG2 cells to validate the hepatoprotective effect of HJ (50~200 ㎍/mL) against ethanol (EtOH, 700 mM)-induced liver damage. Results: HJ effectively reduced the protein expression of sterol regulatory element-binding transcription factor 1, adiponectin, and AMP-activated protein kinase in EtOH-induced HepG2 cells. The levels of ROS, total cholesterol, and triglycerides, which are the result of various synthesis and lipogenesis processes induced by EtOH in the liver, were reduced by HJ. Furthermore, the activities of alcohol dehydrogenase and aldehyde dehydrogenase, enzymes linked to alcohol degradation, were more effectively downregulated by HJ treatment compared to treatment with ZR and PF alone, all without causing cytotoxic effects. Conclusions: HJ protects the liver by inhibiting EtOH-induced lipogenesis, lowering ROS generation, and improving alcohol degradation, which is more effective than ZR and PF alone. Further, in vivo experiments can offer additional evidence regarding the effectiveness, safety, and underlying mechanism of action of HJ.
