Abstract
Purpose
This study suggest the development of a wearable orthotic device pattern that can reduce pain and deformation, and help in the normal development of children with cerebral palsy. Such a pattern enables daily wear before hip subluxation occurs, to prevent hip dislocation and subluxation.
Design/methodology/approach
This study set the design line by carrying out cell work on the actual model, then proceeded with the first pattern design. The final version of the second orthotic device was designed by conducting discussions with experts and the patient's guardian, with the device fitted to the child patient. The evaluation of the second orthotic device used the virtual model to check the pressure area and level through virtual fitting. An evaluation was then conducted with the device fitted to the child patient, to verify the functionality and suitability of the final pattern.
Findings
Following the initial fitting evaluation, the second pattern was presented after modifying and supplementing issues such as movement suitability with posture change, position change of the great trochanter when wearing a diaper, pressure control of the X-shaped band on the genital area and thigh abduction. The master pattern of the final version of the second orthotic device was proposed after confirming that the femoral head of the hip joint was stably fixed, and the compression was applied through a verification based on the virtual fitting using the virtual model, and with the device fitted to the child patient.
Originality/value
With this study, it is expected that the process and design plan for the development of wearable orthotic device patterns for the persons with disabilities impaired mobility can be used as a basic resource to create devices that merge the clothing and medical fields.

Abstract
With the increase in population, the energy needs of countries are also increasing. These countries have difficulties in meeting these increasing needs. Countries that cannot meet this need have to import energy from abroad. This situation adversely affects the current account balance of countries. Nuclear energy investments allow countries to obtain their own energy, although there are some criticisms. In this framework, while some countries in the world increase their nuclear energy investments, some countries do not have any nuclear power plants (NPP). There are 32 such countries where nuclear energy projects are running till date. Therefore, it is very important to determine the socio-economic variables of countries that have nuclear energy investments. In this context, a detailed literature analysis will be made first to determine socio-economic criteria. Then, the importance weights of these factors will be calculated using the Decision Making Trial and Evaluation Laboratory (DEMATEL) method. The profiles of the countries that make nuclear energy investments demonstrate that education level is the most essential socio-economic factor for the improvement of nuclear energy investments. Also, income inequality is another important variable in this regard. However, consumption behaviour and saving behaviour have the lowest weights.

Abstract
Purpose
As the center of the fourth industrial revolution, artificial intelligence (AI) has marked its presence in various disciplines including the education field in the form of AI-powered learning applications. The purpose of this study is to build a research model capturing the relationships among use contexts, user gratification, attitude, learning performance and continuous intention to use an AI-powered English learning application.
Design/methodology/approach
Using the use and gratification theory, use contexts and the belief-attitude-intention theory, this paper uses a quantitative approach based on a survey method for data collection and structural equation modeling for analysis. A total of 478 students from an international university in Guangdong, China, participated in the survey after using Liulishuo for two weeks.
Findings
The results showed that perceived use contexts affected all variables associated with gratifications-obtained and gratification-opportunities. With the exception of social integrativeness, all other gratification-based factors significantly affected attitude. The attitude in turn significantly influenced learning performance and continuous use intention.
Originality/value
Mobile AI-powered learning applications are at the center of research on technology-enhanced learning in the age of media and technology convergence. The study is timely and contributes to the discussion of the roles of use context and gratifications on technology users’ attitudes and behavioral intentions.

Abstract
Purpose
A variety of collaborative technologies have been developed to support design communication among members of design teams, and understanding the affordances of these technologies is critical to effective design collaboration. This research explores the potential of social networking as a collective medium that encourages design communication among student designers at the conceptual stage of design in a studio course.
Design/methodology/approach
For one semester, the student participants used different social networking services to communicate with their team members, and the authors analysed how they collaborated when solving a given problem using the collaborative tools.
Findings
The results show that various social networking platforms support students' communication of design and exploration of problems differently by affecting their clarification of ideas and information sharing. Collective discussion and online support are useful for framing problems and ideation in collaborative design.
Originality/value
This research proposes that social networking services appropriate to the activities needed to be chosen and provided to enable design communication to promote students' active learning through team collaboration.

Abstract
A lot of recent research has been focused on developing network mobility management to support the movement of a mobile network consisting of several mobile nodes. The IETF NEMO working group proposed the NEMO basic support protocol that defines a methodology for supporting such network mobility using bi‐directional tunneling between the home agent and the mobile router. However, this protocol has been found to suffer from the so‐called ‘dog‐leg problem’, and despite alternative research efforts to solve this problem, there are still limitations in the efficiency of real time data transmission and intra‐domain communication. Accordingly, the current paper proposes a new route optimization methodology that uses unidirectional tunneling and a tree‐based intra‐domain routing mechanism. As such, the proposed scheme can provide faster signaling and data transmission and be easily extended to support micro‐mobility without any additional extensions. The performance of the proposed scheme is also evaluated to demonstrate its efficiency.

Abstract
This chapter analyzes how institutional pressures have allowed for continuities as well as brought about changes in modern police organizations in Korea. When facing a legitimacy crisis, the Korean law enforcement system has typically responded with organizational restructuring. Strong myth-building patterns compensate for the lack of moral legitimacy of the police, particularly under authoritarian-military regimes that suppress democratization movements in Korea. Even after seemingly radical organizational changes aimed at placing the police under democratic control, highly institutionalized core structures of the police remain in place. Performance reform after the economic crisis, which was proceeded from reformers’ shared belief in the market-driven solutions, diagnosed the Korean police as a big, inefficient, and self-serving bureaucracy, a diagnosis that eventually caused gradual deterioration in the taken-for-grantedness of policing activities. The internet and social media made the Korean police even more vulnerable to external challenges and a questioning of its legitimacy.

Abstract
Purpose
Rapid prototyping (RP) technology has been widely applied in biomedical research. The purpose of this paper is to describe how a scaffold composite drug delivery system (DDS) was fabricated using a nano composite deposition system (NCDS).
Design/methodology/approach
A biocompatible and biodegradable thermoplastic polymer (poly(DL‐lactide‐co‐glycolide acid)) was used as the matrix, and a mixture of anti‐cancer drug (5‐fluorouracil) and bio‐ceramic (hydroxyapatite – HA) was added to the polymer to form a bio‐composite material for the DDS. An in vitro drug release test showed that the release rate of the drug composite could be controlled by the amount of HA for 50 days.
Findings
Faster release was observed for the DDS with higher weight percent of HA. The relationship between release rate and the amount of HA showed a bi‐linear manner, and bi‐linear drug release models were developed based on the experimental results.
Originality/value
Cylindrical scaffolds were fabricated with polymer/drug/additive using an NCDS. A series of in vitro drug release tests was performed to evaluate the effectiveness of the additive, HA. Drug release models were developed based on the experimental results.

Abstract
Purpose
The purpose of this study is to investigate the effect of brand experiences through cafés or art spaces in luxury fashion flagships on consumers’ buying behavior toward authorized shopping channels.
Design/methodology/approach
Online questionnaires are used by adapting measurements from prior research. We test whether positive relationships exist between multi-faceted (i.e. sensory, emotional, intellectual, and relational) experiences, consumer’s revisiting intention toward the experiential spaces, and the purchase intention of luxury fashion goods from authorized channels, especially focusing on the mediation effect of the intention to revisit. We also include the experiential space type (cafés vs. art exhibitions) as moderator.
Findings
The results confirm that sensory, emotional, intellectual, and relational experiences in cafés or art exhibitions of luxury fashion flagships have a positive impact on the intention to revisit. This revisit intention to experience space has a significant effect on purchase intention from authorized shopping channels. Specifically, sensory experiences in an art space could lead to a positive revisit intention for consumers. Furthermore, relational experiences in cafés could create positive revisit intention in consumers.
Originality/value
This is the first study to compare consumers' perceptions by categorizing extended brand spaces and assessing experiential marketing for authorized shopping channels.

Abstract
Purpose
Mobile technologies have recently come to serve as the primary reservation option for the hospitality industry. This study examines the role of online experience in determining potential consumers' perceived hotel brand image, through a three-stage model based on the stimulus–organism–response (SOR) framework.
Design/methodology/approach
A dual-stage analytical procedure, including structural equation modeling (SEM) and an artificial neural network (ANN) approach, was adopted to test the hypotheses.
Findings
Online experience of mobile applications (apps) can be influenced by perceived usefulness. As the indivisible component of consumers' cognitive beliefs, perceived ease of use exerts a positive impact on online experience. The online experience of mobile apps positively influenced brand awareness and satisfaction, further contributing to potential consumers' brand image formation.
Research limitations/implications
This study empirically verified the relationships among potential hotel consumers' perceptions of official hotel mobile app quality, online experience and brand image.
Practical implications
This study reiterates the importance of official hotel apps in implementing online marketing strategies, suggesting that hoteliers should pay attention to enhancing the quality of their official apps.
Originality/value
This study is one of the first to combine machine learning techniques with the traditional SEM approach to assess linear and nonlinear relationships in consumers' perceptual models. Additionally, the findings provide theoretical insights into the online experience of mobile apps and reveal the perceived brand image formation process of potential consumers.
