Abstract
Purpose
The purpose of this study is structural stability evaluation of umbilical winch. In accordance with the recent trend for developing natural resources, high-technology equipment on exploration ships is becoming more technologically advanced. One such piece of high-technology equipment is the umbilical winch. In this study, the umbilical winch is divided into two parts (drum and winch), where each is respectively designed with three dimensional models using CATIA, and dynamic simulation and structural analysis are performed using ANSYS.
Design/methodology/approach
In this paper, the winch is divided into two parts for finite element analysis, the drum and whole winch model, and the parts are designed as three-dimensional models except for some small parts, such as bolt holes. Dynamic simulation and structural analysis are then performed using ANSYS. The analysis results ensure the reliability of the design methods and will be used in the domestic localization of remote operated vehicle (ROV) launch and recovery systems (LARS).
Findings
The strain is identified from the results, but it is very small. Some stress is concentrated at the lower corner of the drum, but the maximum stress value is lower than the allowable stress; therefore, the structure has no impact on the strain and stress. Thus, it is determined that the designed structure is safe. The results ensure the reliability of the design methods and will be used in the domestic localization of ROV LARS.
Originality/value
Previous studies focus on the static and mechanic problems of the winch by considering winch and drum breakage in the umbilical winch system. However, ships have a nonlinear motion characteristic with six degrees of freedom according to the constant influence of the external environment. In addition, from a design perspective, the dynamic characteristics (e.g. the ship’s motions) are more important than the static characteristics. Thus, the authors focus on winch stability securement with variable loads, such as ships moving, wave disturbance and other such important environment conditions.

Abstract
Purpose
This study aims to understand the reasons for individuals switching from traditional banks to Internet-only banks and examine how switching intentions differ between Generation X and Generation Z. Notably, Generation Z, being digital natives, exhibits distinct characteristics compared to Generation X, who often referred to as digital immigrants. Given the technology-driven nature of Internet-only banks, a multi-group analysis between these two generations was conducted.
Design/methodology/approach
This study utilizes Bansal’s push–pull–mooring model as a framework to analyze switching intention. The study collected survey data from 383 Korean participants, consisting of 198 participants from Generation Z and 185 participants from Generation X.
Findings
The findings indicate that low satisfaction and discomfort are factors that push people to leave traditional banks. Specifically, Generation Z shows a significantly higher inclination to leave traditional banks due to discomfort. On the other hand, relative advantage, compatibility, observability and trialability are factors that pull people to switch to Internet-only banks. Generation X is more likely to consider adopting Internet-only banks when compatibility is high and complexity is low.
Originality/value
This study is the first to explore unique motivators for Generation Z, such as their discomfort with interpersonal interactions in the retail banking sector. These findings challenge earlier research emphasizing human interaction’s importance in technology adoption, offering insights into their future adoption of contactless services.

Abstract
Purpose
Communication plays an important role in health decisions and behaviors. Friends and family exert influence through communication and, when considering smoking, this is particularly salient among those friends and family who smoke. Guided by primary socialization theory and integrated behavioral model, the present study examined the effects of having smoking friends and family on smoking beliefs (e.g. negative consequences, positive reinforcement and negative reinforcement), cultural normative beliefs, pro-smoking injunctive norms, smoking intentions and recent smoking behaviors.
Design/methodology/approach
Cross-sectional online survey data were collected from college students (N = 227). Multivariate analysis of covariance and path analysis were performed.
Findings
College students who reported having smoking friends were more likely to report higher levels of positive reinforcement, cultural normative beliefs, pro-smoking injunctive norms, positive attitudes, smoking intentions and recent smoking behaviors than those without smoking friends. Frequent communication with smoking friends was significantly related to cultural normative beliefs, pro-smoking injunctive norms, positive attitudes and smoking intentions. The analysis, however, did not yield statistical support for the associations between frequent communication with smoking family and smoking perceptions, norms and behaviors.
Originality/value
The present study highlights the vital roles of friends' influence for college students' smoking behaviors. Communication-based intervention can help better equip college students with communication strategies that prevent tobacco use by promoting more effective conversations with friends.

Abstract
Purpose
As interventions are disseminated widely, issues of fidelity and adaptation become increasingly critical to understand. This study aims to describe the types of adaptations made by teachers delivering a school‐based substance use prevention curriculum and their reasons for adapting program content.
Design/methodology/approach
To determine the degree to which implementers adhere to a prevention curriculum, naturally adapt the curriculum, and the reasons implementers give for making adaptations, the study examined lesson adaptations made by the 31 teachers who implemented the keepin’ it REAL drug prevention curriculum in 7th grade classrooms (n=25 schools). Data were collected from teacher self‐reports after each lesson and observer coding of videotaped lessons. From the total sample, 276 lesson videos were randomly selected for observational analysis.
Findings
Teachers self‐reported adapting more than 68 percent of prevention lessons, while independent observers reported more than 97 percent of the observed lessons were adapted in some way. Types of adaptations included: altering the delivery of the lesson by revising the delivery timetable or delivery context; changing content of the lesson by removing, partially covering, revising, or adding content; and altering the designated format of the lesson (such as assigning small group activities to students as individual work). Reasons for adaptation included responding to constraints (time, institutional, personal, and technical), and responding to student needs (students’ abilities to process curriculum content, to enhance student engagement with material).
Research limitations/implications
The study sample was limited to rural schools in the US mid‐Atlantic; however, the results suggest that if programs are to be effectively implemented, program developers need a better understanding of the types of adaptations and reasons implementers provide for adapting curricula.
Practical implications
These descriptive data suggest that prevention curricula be developed in shorter teaching modules, developers reconsider the usefulness of homework, and implementer training and ongoing support might benefit from more attention to different implementation styles.
Originality/value
With nearly half of US public schools implementing some form of evidence‐based substance use prevention program, issues of implementation fidelity and adaptation have become paramount in the field of prevention. The findings from this study reveal the complexity of the types of adaptations teachers make naturally in the classroom to evidence‐based curricula and provide reasons for these adaptations. This information should prove useful for prevention researchers, program developers, and health educators alike.

Abstract
Purpose
The purpose of this paper is to develop a commercialization model based on gaining economic benefits through the transfer of technological capabilities in the oil and gas industry. Since commercialization models are mostly based on the implement of technology to produce and sell new products, this study focuses on developing a specific independent technology commercialization model.
Design/methodology/approach
The method of this research is qualitative based on the grounded theory. For this purpose, general variables with content analysis were extracted by reviewing documents (Literature review) and then for identifying special components, interviewing experts in the Iranian oil and gas industry. Participations were selected using snowball sampling for semistructured interviews.
Findings
The findings of this research were extracted based on grounded theory with data analysis in MAXQDA software. In this research, first, 210 open codes were identified based on qualitative content analysis of relevant documents and results of interviews with experts. Then the classification of open codes was done, and 46 subcategories (variables) were determined in the commercialization model. Finally, 46 subcategories were classified into 10 categories as axial codes in grounded theory as components of the commercialization model.
Research limitations/implications
The results of this research have led to the creation of new practical and theoretical implications. In this research, a new perspective of commercialization with the aim of transferring technology and obtaining its economic benefits for oil and gas industry companies was discussed. Also, based on the practical implications explained in this research, policymakers can use the suggested model to effectively implement independent technology commercialization to acquire economic benefits.
Originality/value
This study is purely original and the outcome of the research conducted by the authors. The research findings are the outcome of in-depth study on technology commercialization in the Iranian oil and gas industry.
