One of the distinctive characteristics of industrial engineering (IE) is its multidisciplinarity. This paper explores the multidisciplinary nature of IE using journal citation network analysis. Using the relatedness indexes of IE journals obtained from journal citation report (JCR), we firstly construct the IE network only composed of 26 IE journals. The resulting IE network is partitioned into three sub-networks: management engineering, manufacturing/quality, and ergonomics. We then propose the IE convergence network which includes 81 related journals in other disciplines as well as 26 IE journals. Scrutinizing the IE convergence network reveals that IE has a high degree of interactions with seven disciplines : Operations Research and Management Science, Statistics and Probability, Manufacturing Engineering, Computer Science, Engineering Design, Business Management, Human Factors and Ergonomics. We investigate the contributions of the related disciplines to IE as well as contributions of IE to the related disciplines. The role of IE journals in exchanging knowledge with related disciplines is also identified by brokerage analysis. It is shown that visualizing and analyzing the IE convergence network can provide an excellent overview of the multidisciplinary structure of IE, which can help IE researchers easily grasp the state-of-the art of IE research.

The purpose of this study was to provide a convergence suggestion of health care and social welfare services by empirically analyzing the effects of chronic diseases and quality of life on subjective health cognition in single-household women aged 60 or over. This study was based on the 2016-2019 Korea National Health and Nutrition Examination Survey, and 1,111 women who had been divorced or bereaved in single-household aged 60 or over were selected. As a result, it was arthritis that showed the largest average difference in subjective health cognition according to the prevalence of chronic diseases. And in the multiple regression analysis that was controlled for demographic characteristics, chronic disease had a negative (-) effect on subjective health cognition, and quality of life had a positive (+) effect on subjective health cognition. The negative (-) factor that had the greatest effect on subjective health cognition was diabetes(-0.084) among chronic diseases, and the positive (+) factor was mobility(+0.173) among the quality of life. Therefore, it suggests that health care services for chronic diseases should be strengthened in order to improve the subjective health cognition of single-person households over 60 years old, and social welfare policies to improve the quality of life should be considered together in a convergence.

This study was conducted to identify the impact of adolescents' dietary behavior on their stress perception and provide basic data for education programs linked to customized nutrition education by gender. In this study, the 2019 Korea Youth Risk Behavior Web-based Survey was used, and a total of 57,303 middle·high school students were selected. Controlling adolescents' age, school record, economic status, residence type, subjective health and body type perception, and the dietary life variables designed with breakfast, fresh foods(fruit, vegetables, milk, water), processed foods(carbonate beverage, energy beverage, sweet beverage, fast food) were analyzed to have an effects on the stress recognition of adolescents. Breakfast had a negative(-) effect on stress perception in all genders of adolescents, and in the case of fresh food, water for boys and fruit for girls had the highest negative(-) effect on stress perception, and in the case of processed foods, energy drink was the dietary factor that had the highest positive(+) effect on adolescents' stress perception. These results suggest that it is necessary to develop a dietary education program tailored to the gender of adolescents to improve their stress perception, and to provide continuous guidance to form a healthy diet.

Collaborative optimization (CO) is a multi-level decomposed methodology for a large-scale multidisciplinary design optimization (MDO). CO is known to have computational and organizational advantages. Its decomposed architecture removes a necessity of direct communication among disciplines, guaranteeing their autonomy. However, CO has several problems at convergence characteristics and computation time. In this study, such features are discussed and some suggestions are made to improve the performance of CO. Only for the system level optimization, genetic algorithm is used and gradient-based method is used for subspace optimizers. Moreover, response surface models are replaced as analyses in subspaces. In this manner, CO is applied to aero-structural design problems of the aircraft wing and its results are compared with the multidisciplinary feasible (MDF) method and the original CO. Through these results, it is verified that the suggested approach improves convergence characteristics and offers a proper solution.

As the significance of knowledge convergence continues to grow, universities are making efforts to develop methods that promote multidisciplinary learning. To address this educational challenge, our paper applies network theory and text mining techniques to analyze university curricula and introduces a graphical syllabus rendering method. Visualizing the course curriculum provides a macro and structured perspective for individuals seeking alternative educational pathways within the existing system. By visualizing the relationships among courses, students can explore different combinations of courses with comprehensive search support. To illustrate our approach, we conduct a detailed demonstration using the syllabus database of Yonsei University. Through the application of our methods, we create visual course networks that reveal the underlying structure of the university curriculum. Our results yield insights into the interconnectedness of courses across various academic majors at Yonsei University. We present both macro visualizations, covering 18 academic majors, and visualizations for a few selected majors. Our analysis using Yonsei University's database not only showcases the value of our methodology but also serves as a practical example of how our approach can facilitate multidisciplinary learning.

In accordance with the rapidly changing social environment, it is becoming more important to cultivate creative and convergent practical talents with flexible thinking skills and problem-solving skills. Therefore, it is necessary for universities to provide educational experiences that enable students to cooperate and converge multidisciplinaryly to carry out on-the-job projects based on what they have learned at school. Therefore, this study designed, developed, and operated with the aim of cultivating creative talents with integrated problem-solving ability through a multidisciplinary capstone design curriculum based on industry-academia cooperation. To this end, the curriculum was developed together by recruiting participating companies and forming a convergence professor team, and it was operated for 15 weeks for students majoring in cosmetics engineering at D University. After the education was over, learning satisfaction and perceived academic achievement were surveyed, and as a result of the analysis, it was found to be above average with 3.77 points and 3.86 points, respectively. And as a result of the in-depth interview on the participation experience, five themes related to the positive experience and three themes related to the negative experience were derived. This study will be able to provide basic data when operating a multidisciplinary convergence capstone design curriculum based on industry-academia cooperation in the future.

Universities that hold engineering education accreditation emphasize the importance of design education. In particular, comprehensive design courses in the engineering field are designed to produce the result reflecting the functional and limiting factors of the design. Systematic design education is also important, but the application of multidisciplinary convergence education is very high in view of the comprehensive design curriculum as a creative education program. This study describes a case study of convergence of curriculum and engineering and design, focusing on the 2019 comprehensive engineering design subject of the researcher. For the collaboration between engineering and design, the process of developing students' ideas and applying them to actual results was presented as the procedures of planning and theme selection, content design, software design, presentation and evaluation. As a result, it is meaningful that the method of convergence between engineering and design was presented without focusing only on technology in the comprehensive design subject of engineering by applying a design that considers the user in producing the work.

Recently Multidisciplinary Design Optimization Based on Independent Subspaces (MDOIS), an MDO (multidisciplinary design optimization) algorithm, has been proposed. In this research, an MDO problem is defined for design of a belt integrated seat considering crashworthiness, and MDOIS is applied to solve the problem. The crash model consists of an airbag, a belt integrated seat (BIS), an energy absorbing steering system, and a safety belt. It is found that the current design problem has two disciplines - structural nonlin- ear analysis and occupant analysis. The interdisciplinary relationship between the disciplines is identified and is addressed in the system analysis step in MDOIS. Interdisciplinary variables are belt load and stiffness of the seat, which are determined in system analysis step. The belt load is passed to the structural analysis subspace and stiffness of the seat back frame to the occupant analysis subspace. Determined design vari- ables in each subspace are passed to the system analysis step. In this way, the design process iterates until the convergence criterion is satisfied. As a result of the design, the weight of the BIS and Head Injury Crite- rion (HIC) of an occupant are reduced with specified constraints satisfied at the same time. Since the system analysis cannot be formulated in an explicit form in the current example, an optimization problem is formu - lated to solve the system analysis. The results from MDOIS are discussed.

This study was conducted to analyze with a focus on gender whether the prevalence of hyperuricemia varies depending on sitting time and high-risk drinking by occupational group. For this study, the Korea National Health and Nutrition Examination Survey data were used, and 16,366 people were selected. The chi-square independence test and logistic regression model were used as the analysis method. The prevalence and risk of hyperuricemia by sitting time were different in the 'agricultural, forestry and fishery skilled workers' only in men. On the other hand, the prevalence with high-risk drinking, both men and women showed differences in 'managers, experts and related workers' and 'office worker'. Also, only women have differences in 'service and sales workers', 'technicians, equipment, machine operation and assembly workers' and 'unemployed'. These results inform men have a higher prevalence and risk of hyperuricemia and suggest that health care policies and medical services are needed to prevent it by occupational group.
