After an earthquake, information regarding potential damage to buildings close to the epicenter is very important during the initial emergency response. This study proposes the use of crowdsourced measured acceleration response data collected from smartphones located within buildings to perform system identification of building structures during earthquake excitations, and the feasibility of the proposed approach is studied. The principal advantage of using crowdsourced smartphone data is the potential to determine the condition of millions of buildings without incurring hardware, installation, and long-term maintenance costs. This study's goal is to assess the feasibility of identifying the lowest fundamental natural frequencies of buildings without knowing the orientations and precise locations of the crowds' smartphones in advance. Both input-output and output-only identification methods are used to identify the lowest fundamental natural frequencies of numerical finite element models of a real building structure. The effects of time synchronization and the orientation alignment between nearby smartphones on the identification results are discussed, and the proposed approach's performance is verified using large-scale shake table tests of a scaled steel building. The presented results illustrate the potential of using crowdsourced smartphone data with the proposed approach to identify the lowest fundamental natural frequencies of building structures, information that should be valuable in making emergency response decisions.
Purpose: Previous research has found that organizational performance pressures and barriers have an effect on the long-term viability of Micro, Small, and Medium Enterprises (MSMEs). Furthermore, MSMEs' intellectual capital and strategic orientation, according to recent research findings, have an impact on this. The goal of this study is to see how intellectual capital and strategic orientation affect MSMEs' performance. Research design, data and methodology: The performance of MSMEs is the dependent variable, with intellectual capital, market orientation, learning orientation, and technical orientation as independent factors. With a sample size of 113 respondents, this research focused on information technology-based MSMEs in Indonesia's Solo Raya area. Data was analyzed use Confirmatory Factor Analysis for the reliability test and path analysis SEM. Results: The interaction between intellectual capital and strategic orientation in respect to MSMEs' performance reveals that innovation capability serves as a partial mediator in the relationship between intellectual capital and technical orientation and organization performance. Conclusions: In general, intellectual capital and strategic orientation have a positive substantial influence on innovation, according to the findings. Furthermore, they have a considerable favorable influence on the performance of MSMEs. It's just that intellectual capital has no discernible impact on knowledge sharing.
In the age of 100 years, it had become very important to prepare for unexpected dangers. This study was conducted to analyze the factors affecting the sales performance of financial planners. We analyzed the influence relationship of sales training, sales management, and customer orientation on sales performance, and furthermore, analyzed the impact of these influence relationships. To this end, sales training was subdivided into customer development, sales competency, and learning agility. Customer orientation was subdivided into the use of customer management system, SNS use, and customer service provision. Sales management was subdivided into goal orientation, manager leadership, and compensation system. The effect of these detailed variables on sales performance was empirically analyzed. To this end, a survey was conducted targeting currently active financial planners. The survey was conducted for a month in January 2023, and 250 valid samples were analyzed. The results of the empirical analysis were as follows. Customer development and learning agility had a significant positive (+) effect on sales performance. Sales competency were not tested for significance. Among customer orientations, SNS use and customer service provision had a significant positive (+) effect on sales performance. The use of the customer management system was not tested for significance. Among sales management, goal orientation and compensation system had a significant positive (+) effect on sales performance. Manager leadership was not tested for significance. The influence of variables that significantly affect sales performance was in the order of goal orientation, customer service provision, compensation system, slearning agility, customer development, and SNS use. Based on these research results, academic and practical implications were presented.

The purpose of this study is to contribute to the development of the women's fashion field with the goal of creating creative and experimental fashion styles through the categorization of cases of women's fashion design expressed with Maximalism, a type of expression used in modern fashion, as well as analyzing and examining the formativeness of this style. Qualitative research was conducted through a literature review and design case analysis. The scope of this research was from 2011 S/S to 2016 F/W, and the regional scope included the women's collections from Paris, Milano, London and New York. The results acquired are as follows. Initially, exaggeration was expressed through excessively exaggerating the overall silhouette of clothing or exaggeratedly distorting certain parts of the overall silhouette. Secondly, decoration was expressed through the use of the same colors and materials and the addition of excessive details and trimmings to express an exaggerated style of clothing as well as to express a luxurious and handcrafted style of clothing. Thirdly, fusion was expressed through integrating multiple items from different cultures, deconstruction, which destroys the concept of gender and use of clothing, and fashion style that transcends time and space. Fourthly, non-structurality was expressed through differentiating multiple weight feelings applied to the left/right sides of clothing or expressing a structural designs that is asymmetrical to the upper/lower/left/right directions to create a silhouette that displays a creative avant-garde style. As examined above, it was found that the maximalism expressed in fashion after 2011 created new images and expressed maximized emotional orientations through the exaggerated use of multiple silhouettes and decorations or through the integration of colors, patterns, ages and images. Through this process, maximalism is expected to not only provide an infinite possibility to the modern fashion that pursues diversification and multiplication, but also serve as an example that represents diversified post-modernism fashion trends in the future.
Perforated plates with cutouts (or holes) are widely used in structural members. These cutouts provide stress concentration in plates. Extensive studies have been carried out on stress concentration in perforated plates, which consider cutout shapes, boundary conditions, bluntness of cutouts, and more. This study presents stress concentration analyses of perforated plates with not only various cutouts and bluntness but also different cutout orientations. Especially, the effect of cutout orientation on stress concentration is emphasized since structural members have become more complicated recently. To obtain stress concentration patterns, a finite element program, ANSYS, is used. For the designated goal, three parameters are considered as follows: the shapes of polygonal cutouts (circle, triangle, and square), bluntness (a counter measure of radius ratio, r/R), and rotation of cutouts (${\theta}$). From the analyses, it is shown that, in general, as bluntness increases, the stress concentration increases, regardless of the shape and rotation. A more important finding is that the stress concentration increases as the cutouts become more oriented from the baseline, which is the positive horizontal axis (+x). This fact demonstrates that the orientation is also a relatively significant design factor to reduce stress concentration. In detail, in the case of the triangle cutout, orienting one side of the triangle cutout to be perpendicular to the applied tensile forces is preferable. Similarly, in the case of the square cutout, it is more advantageous to orient two sides of square cutout to be perpendicular to the applied tensile force. Therefore, at the design stage, determining the direction of a major tensile force is required. Then, by aligning those polygon cutouts properly, we can reduce stress concentration.
The objective of this study is to develop the blind control strategy and method which reduce negative effect of incoming daylight on visual comfort of occupants, minimize psychological anxieties caused by frequent motions of a blind, and maximize positive effect of incoming daylight and solar irradiation by opening/closing of a blind. As previous researches on blind controls have limited outdoor environmental conditions to those in specific regions, orientations and dates, these resulted in problems at various conditions for general-purpose application. Major problem is that the time interval and amount of blind movement do not meet the control objective at the end of control zone and discontinuous curve. To overcome these limitations revealed in the previous researches, following tasks were performed in this study. 1) To establish the control objective to accomplish the goal of this study. 2) To develop the control methods and algorithms which prevent glare on the work-plane at any time and which control the time interval and amount of blind movement to follow the control objective at various profile angle curves. 3) To validate the general-purpose applicability and performance of the developed control methods and algorithms by simulation and its data analysis at various conditions. It was found that the proposed methods and algorithms can prevent the direct glare on the work-plane at all the time and also increase the incoming daylight and solar irradiation.

The purpose of this paper is to examine the effect of entrepreneurial self-efficacy on entrepreneurial intention. Further, the paper aims to study the moderating effect of regulatory focus in the relationship between entrepreneurial self-efficacy and entrepreneurial intention. As per regulatory focus theory, individuals have different goal attainment approaches and underlying motivations; this posits two distinct orientations: promotion focus and prevention focus. Consequently, we hypothesize that the effect of entrepreneurial self-efficacy on entrepreneurial intention would differ depending on the individual's regulatory focus, either promotion or prevention. In order to test the hypotheses, we select a random sample of 494 entrepreneurship students at six universities across the country. The analysis includes a survey of 309 students. The results indicate that students' entrepreneurial self-efficacy has a positive effect on their intention to become entrepreneurs. Further, regulatory focus moderates the relationship between entrepreneurial self-efficacy and entrepreneurial intention. Specifically, the impact of entrepreneurial self-efficacy on entrepreneurial intention is greater in promotion-focused students than in prevention-focused students. The results highlight the need for education methodology that enhances students' entrepreneurial self-efficacy and specialized entrepreneurship education for prevention-focused students.

This study aims to explore latent classes in terms of changing patterns in achievement motivation among the samples from elementary school to middle school students in multicultural families and to investigate factors to predict latent groups and their relationship with academic achievement. 1254 pairs of mother and child from the 1st to 6th years of Multicultural Adolescents Panel Study (MAPS) was utilized for the Latent Class Growth Analysis (LCGA), One-way ANOVA, Multinomial Logistic Regression. The results showed that there were four distinct subgroups within the samples in terms of achievement goal orientations (i.e. very-high changing group, average changing group, low stable group, very-low stable group) at all six time points, and students who reported high achievement motivation were likely to have higher academic achievement. Four groups were extracted based on parent's efficacy, students' self-esteem, and teacher's support. Suggestions and practical implications for understanding the types of subgroups for the achievement motivation of multicultural families were discussed.
Purpose - Nowadays, more than ever before, fierce competition, deep market segmentation, short product life cycles, and intensifying customer needs are putting increasing pressure on franchise's organizations to satisfy their customers by creating market-oriented relationships with and enhancing their market knowledge of them. One way that this might be achieved is by establishing deep ties (i.e., job commitment and job satisfaction) with their employees. Therefore, the purpose of this study is to examine how two important constructs of franchises' strategic efforts, LO (learning orientation) and RMO (relationship marketing orientation), affect job satisfaction, given the mediating role of job commitment. A franchise system comprises a set of contractual arrangements by which mutual obligations are performed. An organizational learning goal motivates employees to improve their abilities and master the tasks they perform. Relationship marketing, in addition, is to identify, establish, maintain, and enhance relationships with customers and other stakeholders to ensure that the objectives of all parties are met and this is done through the mutual exchange of promises. In a relationship marketing orientation, then, a firm creates, maintains, and enhances a strong relationship with its customers by sustaining long-term ties. This study was designed to examine the evolution of various theoretical approaches to franchise systems in order to determine whether theories about firms have significantly affected the franchise system. To this end, the authors developed a structural model consisting of several constructs. Previous studies have suggested that franchises' learning and relationship marketing orientations are important occupational immersion dimensions driving job satisfaction. Research design, data, methodology - We empirically tested a process of how the learning orientation and the relationship marketing orientation influence job commitment and job satisfaction using survey data drawn from 150 responding franchisees who were interviewed about their individual tendencies. Results - The results of this study provide empirical evidence that learning orientation, relationship marketing orientation, and job commitment all influence franchisees' job satisfaction. The results of this study indicate that, first, learning orientation had a significant effect on job satisfaction; second, relationship marketing orientation was positively related to job commitment; third, job commitment had a significant effect on job satisfaction. We also found that relationship marketing orientation and job satisfaction were mediated by job commitment. Conclusions - The findings of this study confirm the importance of learning orientation and relationship marketing orientation in maintaining a positive marketing relationship between franchiser and franchisee from to the perspective of the market. This indicates that franchiser support such as educational programs provided by the franchiser will help franchisees attain higher business management achievement and satisfaction. Moreover, a positive relationship between franchisees and consumers can be maintained through tie effects. Our findings also suggest that learning orientation plays a critical role in job satisfaction within the franchise system.

The aim of this study was to examine the impacts of pre-briefing using structured video simulations in the pre-hospital trauma care simulation-based education on simulation immersion, simulation confidence, and simulation satisfaction. For both the experimental group and the control group, orientations were conducted on the simulation environment. Subsequently, the experimental group watched a video of about 8 minutes, similar to the scenario situation, in which the goal and result of the training were presented. The control group, on the other hand, conducted a classical way of orientation related to the scenario during the same time period. In addition, the experimental group and the control group underwent simulation practice in the same situation for 12 minutes, and debriefing was performed for 40 minutes by the same research assistant. Afterwards, we measured the simulation immersion, confidence, and satisfaction of the participants. Data were analyzed using χ2 and independent t-test using the SPSS 22.0 program. It was found that the experimental group that conducted the pre-briefing using video had higher immersion and confidence than the control group. On the other hand, satisfaction was not significantly different between the two groups. The results indicate that pre-briefing using structured video was an effective educational method to increase simulation immersion and simulation confidence.
