This study uses various methods, including media analysis, expert interviews, and large-scale surveys, to derive notable digital business trends in 2023. Most trend studies have yet to deal with digital business trends in Korea. They also often have limitations in the objectivity of the results using unclear methods. On the other hand, this study emphasizes the validity of the results by collecting opinions from Korean digital business experts in various fields. First, Korean IT news articles were collected and analyzed through topic modeling analysis. Then, based on the results, interviews were conducted with 13 academic and industrial experts to derive 16 IT business trend candidates. Then, a survey was conducted on 210 experts to finalize the list of Korean IT business trends. Finally, to compare overseas and domestic views, we conducted an additional survey using the items developed by the Society for Information Management, SIM. This study is meaningful in that it drew prospects for digital business trends in consideration of the domestic business environment by scientifically converging various opinions of Korean digital business leaders. Our study contributes to developing strategies for IT technology and IT service business markets.

This study investigates the typology of Internet business models according to revenue sources, and empirically tests how the revenue sources of each Internet business model are different each other. This study consists of the following two steps. First, AHP(Analytic Hierarchy Process) is adopted in developing the influential factors(indexes) for the profitability of each Internet business model and the weight score of each factor. The questionnaire for AHP consists of 47 questions on 9-point scales, and was distributed to 10 experts on Internet business model. Expert Choice program has been used for analysis. Second, the questionnaire to survey the current profitability of each Internet business model was developed on 5-point scale. In order to analyze the actual revenue quality and source of Internet business models, we used MANOVA and ANOVA. This study contributes to develop the desirable revenue or profit model of each Internet business model, and also provides a reference in evaluation of the revenue quality of Internet business models.

Generally, the method of the policy analysis has been used for making a policy decision of the development project of the road through the expert interview based on AHP. According to introducing PI, the study of the method of the integrating process for various opinion of the related groups is required. On this study I evaluate what is a difference between the results of integrated process and the AHP analysis on what is major considering factor in decision-making process. From the analysis, each evaluate factor is in level of significance by ANOVA. First, there is a significance level difference between Group A, C and Group B Second, there is also a significance level difference on the result of AHP analysis for each group in order to evaluate by integrated method. Finally, the method of AHP analysis which considers priority factor is expected as to be useful tool on decision-making of various group.

AHP는 원래 단일 의사결정자의 분석도구로 개발된 다속성 의사결정기법이지만 복잡한 시스템에 대해서는 여러 전문가가 참여하는 집단의사결정에 많이 쓰인다. AHP를 집단의사결정에 이용하기 위해서는 첫째, 전문가들의 의견을 종합하는 방법론의 문제와 둘째, 신속하고 정확한 의견수립의 도구문제가 해결되어야한다. 이 논문에서는 전문가들이 제시한 비교행렬들로부터 하나의 중요도(combined priority)를 구하는 베이지안 방법을 정리하고, 이를 바탕으로 웹 기반에서 AHP의사결정에 대한 설문지를 작성하여 의견을 수립하고 분석할 수 있는 의사결정 시스템을 제시한다. 개발된 시스템의 구성 및 특성을 설명하고 가상의 의사결정 문제를 통하여 시스템의 기능과 사용방법 및 화면설계 등을 예시한다.

Currently, safety management is becoming important at domestic construction sites. Despite the importance of safety management, accidents at construction sites are steadily increasing. Fire accidents among safety accidents cause not only negative effects on schedule delay or work plans at construction sites, but also huge casualties. Therefore, the purpose of this research is to extract the causes of fire at the construction site through the case of fire at the construction site, and to prioritize prevention through the analysis of the factors to contribute to the prevention of fire. As a research method, we select fire factors through case, conduct surveys through expert group, and analyze survey through AHP technique. The results of the AHP analysis of the survey of expert groups showed that the workers and their sub-item ranked high.

To keep pace with rapidly changing social and technological trends, the Department of Mechanical and System Design Engineering at Hongik University is in the process of updating teaching materials and learning methodologies while evaluating/revising our existing curriculum. In order to be better apprised of the employment needs and student aspirations, we have conducted three separate but related surveys by targeting experienced professionals and managers, alumni working in industries as practising engineers, and our current students. The surveys have furnished us with valuable insights that, we hope, will lead to a new curriculum and learning methods more in tune with needs of our students as well as their future employers. Among other findings, the analysis of the survey responses points towards expansion of integrated laboratory and design experiences, cultivation of improved written and oral communication capabilities involving individual and team efforts, and development of interdisciplinary courses encompassing related fields of engineering as well as emerging fields such as nano and information technologies.
