  • Background: As the Positive List System (PLS) is implemented in broad application to agricultural products, attention to the correct use of pesticides is also needed in the production of mulberry leaves and fruit. In this regard, three types of pesticides against mulberry popcorn disease were applied 2 - 3 times both in the field and greenhouses to prepare safety standards. Residual pesticide analysis was conducted on mulberry fruits and leaves. Methods and results: Three pesticieds, thiophanate-methyl, thiophanate-methyl·triflumizole and fluopyram registered as PLS pesticides for mulberry popcorn disease, were sprayed in the Wanju and in Buan regions, after which residual pesticide analysis was conducted using high-performance liquid chromatography (HPLC). As three pesticieds were either undetected or below the permissible level in mulberry fruit, demonstrating that they were suitable for safe spraying. However, 5.6 mg/kg of thiophanate-methyl was detected in the greenhouse after three application, which was slightly above maximum residue limit (MRL). Furthermore the level of thiophanate-methyl·triflumizole was higher than 0.2 mg/kg ("Gwasang No. 2" variety, spraying twice) or similar to 0.09 mg/kg ("Daesim" variety, spraying thrice) the permissible level (0.1T mg/kg) as the thiophanate-methyl was detected in mulberry leaves in the greenhouse. Conclusions: The spraying frequency for controlling mulberry popcorn disease in greenhouses should be limited to two times or less, especially when mulberry leaves are treated with thiophanate-methyl·triflumizole careful consideration is required if the leaves are to be used as food materials.

  • The Fintech services provide innovation to financial services users using various mobile devices and computers in wired and wireless communication environments. In this study, we develope a theoretical research framework to explain the psychology of Fintech services users based on a cognitive, affective, and conative framework. Using this framework, this study analyzes the relationships between the cognitive characteristics (i.e., innovation, relative advantage, ease of use, and usefulness), emotional characteristic (i.e., attitude), and behavioral characteristic (i.e., actual use) toward Fintech services users. This study conducted an online survey of people who have experienced using Fintech services. And the data of the collected Fintech services users was analyzed using structural equation model software (i.e., SMART PLS 2.0 M3). The results of the empirical analysis show the relationships between innovation, relative advantage, perceived usefulness, perceived ease of use, attitude, and actual use of Fintech service users. The results of this study provide useful information to improve the practical use of Fintech services users in the Internet of Things (IoT) environment.

  • This study examines the level of port service quality based on $Gr{\ddot{o}}nroos$(1984)'s Two-Dimensional Model: we investigated service-environment quality and service-delivery quality, and added service-product quality as a process quality. This study focused on a service user like a llner, forwarder, shipper, or a logistics firm using port service in the Port of Busan. We investigated relationships among the following vairables: service quality, customer satisfaction and port image; we also analyzed the path coefficients using Smart-PLS 3.0. The results and suggestions of this study are summarized as follows. First, all of the service quality variables influenced customer satisfaction but service-delivery quality didn't have an impact on port image. Secondly, there is correlation between customer satisfaction and port image; customer satisfaction had a positive effect with port image. Lastly, customer satisfaction and port image influenced the Relation Continuity Intention.

  • This study aims to examine the impact of service recovery in building customer loyalty through the mediating role of customer satisfaction and corporate image. This study also aims to examine the reciprocal relationship between customer satisfaction and corporate image in building customer loyalty. This study uses data from 126 consumers who have received recovery for a service failure in five logistics companies which operates in Southeast Sulawesi in Indonesia, namely; JNEs; J&T Express; Pandu Logistics; MEC; and TiKi. Data was collected using a questionnaire which was then distributed to all respondents via google form. The distribution of respondents at each logistics company provider was as follows: 19 respondents were customers of JNEs; 17 respondents were customers of J&T Express; 32 respondents were customers of Pandu Logistics; 21 respondents were customers of MEC; and 37 respondents were customers of TiKi's. The structural model developed in this study was tested using Partial Least Squared (PLS) method. The research found that service recovery has a direct effect on customer satisfaction and corporate image as positive and significant. Customer satisfaction and corporate image have a reciprocal relationship which then roles in building customer loyalty. Service recovery has an indirect effect on customer loyalty through the mediating role of customer satisfaction and corporate image.

  • The purpose of this study is to examine the relationship between POS, JR, and Innovation, and to explore the role of job psychological empowerment as a mediator in this relationship. A structured questionnaire was distributed to 25 companies in the petrochemical industry. PLS-SEM 4 was used to analyze the data of 100 valid responses. These findings suggest that employee empowerment (EMPOW) fully mediates the relationship between job resourcefulness (JR) and Innovation (INNOV). The total effect of JR on INNOV is also significant, with a beta coefficient of 0.234 and a t-value of 3.375. However, when the mediating influence of EMPOW is taken into account, the effect of JR on INNOV is no longer significant, with a beta coefficient of 0.100 and a t-value of 1.610. This suggests that EMPOW plays a key role in the relationship between JR and INNOV and that JR may not have a direct impact on Innovation. The study informs the development of interventions or strategies for promoting Innovation in organizations by identifying key factors that facilitate or inhibit the innovation process. The study further contributes to the development of new theories or models on the relationship between perceived organizational support, job resourcefulness, psychological empowerment, and Innovation.

  • Purpose: The beauty market is growing rapidly and becoming more competitive as new shops enter the market and offer similar products and services. The way for industries such as beauty shops to succeed in market competition is to understand customer needs and provide a marketing mix appropriate for those needs. Research design, data, and methodology: The survey was conducted for a total of 4 days from October 4 to October 7, 2023, and a total of 2,431 copies were distributed and 463 copies were returned. Excluding 2 copies with insincere responses, 461 copies were used for analysis. The data were analyzed with SPSS 25.0 and SamrtPLS 4.0. Result: Product, price, promotion, people, and physical evidence influence perceived value, but place and process didn't. Product, process, and physical evidence influence reputation, but price, location, promotion, and people didn't. Perceived value influences revisit intention but did not reputation. Reputation influences revisit intention. Conclusions: First, beauty shops must develop beauty services that can satisfy customers' needs. Second, beauty shops must continue to invest in external facilities and interior design. Third, intangible service processes can help the beauty shop's reputation. Fourth, beauty shops need to maintain a balance between price and perceived value so that customers can be satisfied with the service experience.

  • Contemporary organizations strive for customer agility through the deployment of digital technologies on customer-focused operations to build enduring customer relationships, with mobile apps being one of its prominent examples. Drawing on prior agility and ECT literature, this study proposes a model to examine customers' view of a firm's customer agility. Our empirical test of conceptual model from data collected in a field study from 128 customers demonstrated that the conceptual model offers good explanation for customers' view of a firm's customer agility through relationships among customer expectations-customer perceived firm's responsiveness-satisfaction. Data were analyzed using PLS, polynomial modeling, and response surface methodology to examine the relationships between customers' digital interactions with the firm, influence of digitized interactions on customer expectations, customers' evaluation of firm's responsiveness, and subsequent customer satisfaction.

  • The vacuum gauge control system has been designed and implemented using multi-serial communication controllers (MSCC) for the 2.5 Gev storage ring at the Pohang Accelerator Laboratory (PAL). There are 20 Balzers vacuum gauges and 17 Granville-Phillips vacuum gauges at the storage ring. A MSCC have two RS485 (max speed 460.8Kbps) field network port, 8 channel serial communication ports (max speed 460.8Kbps) connected to gauge controller for serial communication control. 12 MSCCs are connected to a personal computer (PC) through the RS485 field network. The PC can automatically control the MSCCs by sending set of commands through the network. The commands specify the duration of the MODBUS protocol. Upon receiving a command from a PC running under Windows2000 through the network, the MSCC communicate through the serial output ports to gauge controller. In this paper, we describe control structure and scheme of the vacuum gauge control system.

  • This study adopts organismic integration theory (OIT) to classify and contrast the predominant roles of five motivations (i.e., economic incentives, self-presentation, information acquisition, altruism, and enjoyment) in fostering three levels of behavioral engagement on brand-related social media content. This study further examines the moderating effect of personality (thinkers vs. feelers) on these relationships. The results of PLS-SEM reveal the greater impact of autonomous motivations on content consumption (enjoyment and information acquisition) and content contribution and creation (altruism and information acquisition), compared with controlled motivations (self-presentation and economic incentives). This study also finds that thinkers mostly engage on brand-related content for information acquisition and economic incentives, whereas feelers are mostly driven by enjoyment for content consumption and by altruism for content contribution and creation. This study addresses the inconsistency in prior research findings and provides practical implications to social media marketers.
