In response to the growing focus on products utilizing character IP in retail, this study investigated the impact of consumers' recollection of character IP fashion products on brand relationship formation. Furthermore, it explores the moderating effect of consumer preferences for collaboration series on this relationship. Participants were consumers who recalled character IP fashion products, and the analysis was conducted using PLS-SEM. The findings show that consumer recollection associated with character IP in fashion products positively affects brand attachment, leading to a positive impact on brand attitude and brand loyalty. The study also highlights the effectiveness of repeated exposure to similar products as an effective marketing strategy. Furthermore, a positive synergy between brand attachment and preferences for collaboration series enhances brand loyalty by influencing consumer attitudes. The study suggests that collaboration series marketing strategies affect consumers' perceptions of novelty and alter their expectations. This research has significant academic and practical implications, demonstrating the effectiveness of marketing through collaboration series and revealing how character IP in fashion products, commonly used by fashion brands, shapes brand-consumer relationships. The findings provide a robust theoretical foundation for marketing strategies leveraging character IP.

The stabilization control of inverted pendulum (IP) system is difficult because of its nonlinearity and structural unstability. In this paper, an Evolving Neural Network Controller (ENNC) without Error Back Propagation (EBP) is presented. An ENNC is described simply by genetic representation using an encoding strategy for types and slope values of each active functions, biases, weights and so on. By an evolutionary programming which has three genetic operation; selection, crossover and mutation, the predetermine controller is optimally evolved by updating simultaneously the connection patterns and weights of the neural networks. The performances of the proposed ENNC(PENNC)are compared with the one of conventional optimal controller and the conventional evolving neural network controller (CENNC) through the simulation and experimental results. And we showed that the finally optimized PENNC was very useful in the stabilization control of an IP system.

A practical application of a supercapacitor energy storage system in a polarization instrument is proposed on the basis of the energy storage requirements of an induced polarization (IP) transmitter for geophysical exploration. We focused on the energy storage system of a supercapacitor, the topology of the power converter, and the system control strategy as key technologies, and we performed theoretical research and experimental tests on the system and developed an experimental platform. The experiments validated the theoretical research on the key technologies of the supercapacitor energy storage system and demonstrated the effectiveness of the innovation. Results showed that the storage system is efficient and satisfies the energy storage needs of the IP transmitter.

Automatic Repeat reQuest (ARQ) is a very effective technique against transmission error at the medium access control (MAC) layer. An erroneous MAC protocol data unit can be typically retransmitted within a given limit. In order to improve the IP-level performance, which directly affects the user-perceived quality-of-service (QoS), we propose a new truncated ARQ strategy, called MAC service data unit-based ARQ (S-ARQ), where the finite number of opportunities for retransmissions are shared by multiple fragments out of an IP datagram. We describe how SARQ can be implemented in a practical system, and then propose another variant of S-ARQ employing a functionality called early detection of failure. Basically, we evaluate the performance of SARQ in two different manners. First, assuming i.i.d. error process, we analyze both the probability of the delivery failure and the average delay of IP datagram. Then, we assess the performance of S-ARQ via simulation over a 2-state Markov channel.

Breast cancer is the first or second malignancy among women worldwide. Illness perception (IP) and quality of life (QoL) are major issues considering breast cancer management. An attempt was here made to inspect the predictive variables influencing IP and their impact on QoL in cancer patients. The key predictors adapted from previous studies including life satisfaction, perceived social support, self-esteem, hope, optimism, and spiritual well being were taken into account. Our sample included 200 female volunteers suffering from breast cancer applying exclusion criteria. The data were collected using various questionnaires and statistically analyzed by means of path analysis and structural equation modeling. The results revealed that of the six predictors, spiritual well being and social support had direct effects on QoL and IP. The only path with significant indirect correlation with IP was social support. Spiritual well being had the second significant direct effect on IP. Self-esteem occupied the third rank in direct effects on both QoL and IP. In conclusion, here in Iran and most likely in other strongly religious communities, spiritual intervention is an effective strategy to raise QoL. Also social support helps women suffering from breast cancer to experience better conception and coping strategies.

The development of liquid CO₂ storage tanks and liquid CO₂ handling technology are key for liquid CO₂ carriers, and it is necessary to extract core patents of competitors that may lead to patent disputes in the future, establish response strategies, and strengthen the IP portfolio by creating new IPs. As a result of patent analysis for this purpose, patent applications and technology development are being led by the three large domestic shipbuilding companies(Hyundai, Samsung, and Hanwha) and the large Japanese shipbuilding company(MHI), and the handling of liquid CO₂ storage tanks and liquid CO₂ (prevention of dry ice formation) Technology-related patent applications and technology development are actively taking place, so there may be concerns about patent infringement. Currently, It has been confirmed that there are no core patents that are likely to cause patent disputes in the future. However, the technology concept in question lacks patentability as it is a combination of known technologies, so the creation of new IP is necessary to establish exclusive rights. Accordingly, through this project, four new IP creations and patent applications based on competitors' patents were completed. ① Technology to prevent the release of dry ice during unloading using filters, ② Technology to prevent the creation of dry ice in the unloading piping during unloading, ③ BOG reliquefaction technology to respond to CO₂ emission ban regulations, and ④ Technology that can utilize BOG within ships.

LED (Light Emitting Diode) lighting is gaining more and more market penetration as one of the global warming countermeasures. LED is the next generation of fusion source composed of epi/chip/packaging of semiconductor process technology and optical/information/communication technology. LED has been applied to the existing industry areas, for example, automobiles, TVs, smartphones, laptops, refrigerators and street lamps. Therefore, LED makers have been striving to achieve the leading position in the global competition through development of core source technologies even before the promotion and adoption of LED technology as the next generation growth engine with eco-friendly characteristics. However, there has been a point of view on the cost compared to conventional lighting as a large obstacle to market penetration of LED. Therefore, companies are developing a Chip-Scale Packaging (CSP) LED technology to improve performance and reduce manufacturing costs. In this study, we perform patent analysis associated with Flip-Chip CSP LED and flow chart for promising technology forecasting. Based on our analysis, we select key patents and key patent players to derive the business strategy for the business success of Flip-Chip CSP PKG LED products.

The stabilization control of Inverted Pendulum(IP) system is difficult because of its nonlinearity and structural unstability. Futhermore, a series of conventional techniques such as the pole placement and the optimal control based on the local linearizations have narrow stabilizable regions. At the same time, the fine tunings of their gain parameters are also troublesome. Thus, in this paper, an Evolving Neural Network Controller(ENNC) which its structure and its connection weights are optimized simultaneously by Real Variable Elitist Genetic Algorithm(RVEGA) was presented for stabilization of an IP system with nonlinearity. This proposed ENNC was described by a simple genetic chromosome. And the deletion of neuron, the according to the various flag types. Therefore, the connection weights, its structure and the neuron types in the given ENNC can be optimized by the proposed evolution strategy. And the proposed ENNC was implemented successfully on the ADA-2310 data acquisition board and the 80586 microprocessor in order to stabilize the IP system. Through the simulation and experimental results, we showed that the finally acquired optimal ENNC was very useful in the stabilization control of IP system.
