Background: Recent cases of spinal cord infarction combined with cerebral infarction have demonstrated improved walking ability through pharmacological treatment and rehabilitation. However, studies on the efficacy of multidisciplinary approaches remain limited. Objectives: This study aimed to investigate rehabilitation strategies and establish a foundation for clinical practice, focusing on physical and occupational therapy for patients with spinal cord and cerebral infarctions. Design: A case study. Methods: A 70-year-old woman with combined spinal cord and cerebral infarction underwent 20 weeks of rehabilitation. Functional outcomes were assessed using Grip Strength, Manual Muscle Test (MMT), Trunk Impairment Scale (TIS), Manual Function Test (MFT), Berg Balance Scale (BBS), 10-Meter Walking Test (10MWT), and Korean Modified Barthel Index (K-MBI). Results: Over 20 weeks, Grip Strength improved to 6 kg (left) and 13 kg (right), MMT increased from 97 to 103 points, and TIS improved from 2 to 10 points. MFT scores increased to 18 (left) and 25 (right). BBS improved from 1 to 23 points, and the 10MWT time decreased to 19.84 seconds. K-MBI scores rose from 12 to 39 points. Conclusion: A multidisciplinary approach, including robotic therapy, significantly improved functional recovery, facilitating reintegration into daily life.

This study investigates the cognitive characteristics and transition flow of team mental models in virtual reality environments (VRE) compared to Zoom-based collaboration during fashion design problem-solving processes. Using the VRE platform Spatial.io as a case study, the study examines how virtual reality technologies influence the formation of shared mental models among collaborators. The objective is to identify key cognitive features that VREs offer to support problem-solving in multidisciplinary fashion design collaborations. The study employed a comparative experimental design, involving professionals from fashion design, marketing, and production. Participants completed the design concept generation tasks in both VRE and Zoom environments, all interactions were recorded and coded, with the analysis focusing on cognitive transitions, verbal dynamics, and collaborative behavior patterns across both environments. The results reveal that VRE fosters higher frequencies of environmental interaction (EI-EI), cognitive integration (CIM-CI), and planning to execution transitions in team interactions (PP-PIM), forming multidirectional feedback loops. These features enhanced dynamic adaptation to environmental stimuli. In contrast, Zoom-based collaboration relied heavily on linear verbal communication, with fewer cognitive transitions and limited structural feedback loops, thereby reducing efficiency in idea evaluation and execution in team interaction. The study highlights the potential of VREs to transform collaborative practices in fashion design by enabling immersive and multidimensional interactions, contributing to advancing digital collaboration strategies in creative industries, with implications for education and interdisciplinary innovation.

Multidisciplinary Design Optimization(MDO) method that considers principles in various fields affecting big scale structure and system design at the same time is used. Because most variables are connected many engineering phenomena under the classic optimized design method(all-in-one design approach), it is hard to judge the meaning of final design solution obtained, and there are cases where all variables converge before reaching the optimal design value in large-scale design problems with many variables. Collaborative Optimization (CO) method, the most advanced MDO approach, is used to efficiently solve these optimum problems, to efficiently analyze design problems involving numerous design variables and constraints and in which various engineering phenomena occur. However, the application of the MDO problem to CO introduces a number of numerical problems by destroying the numerical properties of the original optimal design problem. Therefore, this study researches one solution by listing the problems of CO after organizing various approaches of MDO.

The most important aspect of the imaging role for indeterminate bile duct stricture is to make a differential diagnosis on whether the stricture is highly likely to be malignant or benign. Compared to benign stricture, malignant stricture is longer, thicker, and has indistinct outer border and irregularity of the lumen in contrastenhanced computed tomography and magnetic resonance (MR). Also, in the contrast-enhanced portal phase, malignant stricture has a stronger enhancement than the liver parenchyma. There are studies to differentiate between malignant and benign stricture in diffusion weighted image, a functional MR image, but there remains controversial. Sometimes, malignant biliary stricture may be caused by bile duct invasion of gallbladder cancer, pancreatic cancer, hepatocellular carcinoma, biliary metastasis, and lymphoma. Among the potential causes of indeterminate biliary stricture, the characteristics of multifocal biliary stricture mainly suggest benign sclerosing cholangitis, and various external compression factors that cause biliary stricture can be differentiated by radiologic imaging. There are causes of biliary dilatation without obstructive lesion, radiologic diagnosis can be made by considering various characteristics.

In system design, it is not always possible that all decision makers can cooperate fully and thus avoid conflict. They each control a specified subset of design variables and seek to minimize their own cost functions subject to their individual constraints. However, a system management team makes every effort to coordinate multiple disciplines and overcome such noncooperative environment. Although full cooperation is difficult to achieve, noncooperation also should be avoided as possible. Our approach is to predict the results of their cooperation and generate approximate Pareto set for their multiple objectives. The Pareto set can be obtained according to the degree of one's conceding coupling variables in the other's favor. We employ approximation concept for modelling this coordination and the mutiobjective genetic algorithm for exploring the coupling variable space for obtaining an approximate Pareto set. The approximation management concept is also used for improving the accuracy of the Pareto set. The exploration for the coupling variable space is more efficient because of its smaller dimension than the design variable space. Also, our approach doesn't force the disciplines to change their own way of running analysis and synthesis tools. Since the decision making process is not sequential, the required time can be reduced comparing to the existing multidisciplinary design optimization. This approach is applied to some mathematical examples and structural optimization problems.

The cosmetic industry has been rapidly expanding over the last decades. The industry itself generates about $230 billion each year and is consumed daily by 90% of female consumers. Despite its weight in the economy, consumer research has largely neglected the specificity of beauty products and consumption. The first aim of this paper is thus to offer an integrative conceptual framework to better understand beauty consumption from a consumer psychology point of view, incorporating findings from evolutionary, cognitive and cultural psychology. The second aim is to encourage consumer research on the topic by offering a research agenda taking into consideration different dimensions of beauty perception. This working paper is based on a critical and systematic literature review conducted on the topic of beauty in cognitive, evolutionary and cultural psychology. Whilst the beauty industry is booming, a gap exists in the consumer research literature in terms of understanding the applications of traditional evolutionary, cognitive and crosscultural research on the topic. This working paper introduces a framework and agenda to understand, frame, and study beauty in consumer research. On the basis of the literature reviewed, we propose a model with two decision-making systems related to beautyrelated cognition and behaviors: an impulsive decision-making system and a socially constructed decision-making system. In the impulsive decision-making system, sexual selection and cognitive mechanisms function simultaneously. We expect impulsive buying behavior to occur when consumers are exposed to highly aesthetic packaging of beauty products. In the socially constructed decision-making system, consumers choose certain brands depending on the brand image being aligned with the consumer’s cultural perception of beauty. We argue that decision-making behavior is reflective, as opposed to impulsive. Finally, we argue that both systems are mutually reinforcing and need to be better integrated into further studies looking at beauty consumption.
