This paper aims to analyze the influence of innovation capabilities on the relationship between strategic orientation and the performance of women small and medium entrepreneurs (SMEs). The strategic orientation in this study used three constructs, namely market orientation, learning orientation, and technology orientation. The method of data collection was the survey method and was collected from 149 SMEs in the typical culinary industry in Indonesia using probability samples. The data analysis method uses path analysis. The results showed that the influence of strategic orientation on business performance has strengthened previous studies. However, in this study strategic orientation that directly affects business performance is market orientation and learning orientation, while technology orientation has no direct effect. The existence of innovation capability as a mediation variable strengthens the influence of strategic orientation on business performance. The results of this study also showed that the ability of innovation has a positive and significant effect on the performance of women entrepreneurs in Indonesia. The contribution of this research pays special attention to the strategic orientation of women entrepreneurs engaged in the culinary business in Indonesia.

One of the most fundamental challenges when designing controllers for dynamic systems is the adjustment of controller parameters. Usually the system model is used to get the initial controller, but eventually the controller parameters must be manually adjusted in the real system to achieve the best performance. To avoid this manual tuning step, data-driven methods such as machine learning were used. Recently, reinforcement learning became one alternative of this problem to be considered as an agent learns policies in large state space with trial-and-error Markov Decision Process (MDP) which is widely used in the field of robotics. However, on initial training step, as an agent tries to explore to the new state space with random action and acts directly on the controller parameters in real systems, MDP can lead the system safety-critical system failures. Therefore, the issue of 'safe exploration' became important. In this paper we meet 'safe exploration' condition with Control Barrier Function (CBF) which converts direct constraints on the state space to the implicit constraint of the control inputs. Given an initial low-performance controller, it automatically optimizes the parameters of the control law while ensuring safety by the CBF so that the agent can learn how to predict and control unknown and often stochastic environments. Simulation results on a quadrotor UAV indicate that the proposed method can safely optimize controller parameters quickly and automatically.

The purpose of this study was to investigate the effect of academic self-efficacy, task value, behavioral participation, cognitive participation, emotional participation, and initiative participation on learning satisfaction in 462 college students who took a flip learning class. Results, As for the direct effect of variables affecting learning satisfaction, behavioral participation was the largest factor, followed by initiative participation, task value, emotional participation, and academic self-efficacy. These variables explained 86% of learning satisfaction. Academic self-efficacy and task value had an indirect effect on learning satisfaction through behavioral, emotional, and proactive participation. In the multi-group moderating effect with the upper-middle class (B+ or higher) and the lower-middle class (below B) group as the moderating variables, there was a partial moderating effect because the path coefficients of leading participation and learning satisfaction differed between the groups. It is necessary to seek various ways to increase the degree of participation in learning and to develop an intervention strategy through a program tailored to each individual.

This study aimed to investigate the current utilization and implications of digital learning support media in the field of French studies, and to explore future research directions. To achieve this, we conducted a comprehensive review of the use of digital media in various learning processes within French studies. Additionally, we examined the direct application of ChatGPT, an emerging technology, to learning by extending its use to foreign language and education fields. Our findings indicate that the application of digital learning support media in French studies is somewhat limited, with selective use in processes such as online class support media, pre-class learning, efficient learning and interaction, and self-directed learning. In the case of ChatGPT, our research found that no studies have been conducted within French studies, and very few studies have been conducted on its practical application in other educational fields. While ChatGPT has a wide range of applications and has shown positive effects on learners, ethical concerns have been raised regarding the quality, source, and reliability of information. Therefore, future research in French studies should focus on educational application and effectiveness verification in university teaching and learning situations, as well as interdisciplinary convergence with digital learning support media.

This article is to advance the connection between students' achievements and meditation and to explore the direct relationship between two factors by performing meditation in class, which has not been researched. As a result of study, I am convinced that meditation has a positive relation with achievements and many further experiments and researches (This article suggested many kinds of meditation.) will surely confirm this fact.

An extension of interaction matrix formulation to the problem of system and disturbance identification for a plant that is corrupter by both process and output disturbances is presented. With only an assumed upper bound on the order of the system and an assumed upper bound on the number of disturbance frequencies, it is shown that both the disturbance-free model and disturbance effect can be recovered exactly from disturbance-corrupted input-output data without direct measurement of the periodic disturbances. The rich information returned by the identification can be used by a performance-oriented model-based loaming or repetitive control system to eliminate unwanted periodic disturbances.

In this paper, a DLC method is suggested for linear feedback systems to improve the tracking performance when the task of the system is repetitive. DLC can generate the desired control input directly from the previously teamed control inputs corresponding to other output trajectories. It is assumed that all outputs considered in this paper have some relations called "proportionality. " To show the validity and tracking performance of the proposed method, some simulation are performed for the tracking control of a linear system with a PI controller.

Food is a fundamental aspect of human life, encompassing the cultural essentials of clothing, shelter, and sustenance. Experiencing the culture of individuals who speak the language one is learning through food has proven to be an effective means of enhancing learners' motivation. It can be presumed that direct exposure to Korean cuisine, either through consumption or preparation, will exert a profoundly positive psychological impact on Korean learners, contributing to psychological healing, indirectly evidenced by stress reduction. Therefore, this study conducted a survey among Korean learners in Japan to investigate the potential for psychological healing through engagement with Korean food.

This study is to evaluate the effectiveness of problem-solving ability by applying a team-based learning model to the classes of humanities and social science students, and to conduct a structural model analysis on the relationship between sub-factors. Team-based learning was conducted six times in six teams with 30 students in the second and third grades of the humanities and social sciences. The problem solving ability score of the target students was significantly higher after team-based learning and was statistically significant. There was no problem in normality with the latent variables, which are the sub-factors of problem solving ability, and the factor load value was statistically significant at the .001 level in the confirmatory factor analysis of the observed variables for the latent variables, which was a valid model. A good level of fitness was also shown in the verification of the fitness of the research model. As a result, it was analyzed that latent variables of cause analysis, problem clarification, planning execution, performance evaluation, and alternative development had an indirect or direct influence on each other.
