  • The focus of this study is to analyze between South Korea and China in terms of diversity in Management Information Systems research. As a result, there is herding phenomenon regarding researches in both of the countries compared to other previous studies. There also seemed to be lack of in-depth study of basic theories and connection to related field of study considering the broad topics of management information, unlike other international journals that pursue diversity in control referencing various methodologies, analysis units and many citations. Therefore, both South Korea and China should stabilize theoretical base of MIS through securing independent field of MIS along with founding the fundamentals by searching in diversified fields, methodologies and analysis units with focused topics. The upshot here is that with respect to diversity in MIS from both countries, to alleviate herding phenomenon, enforcing accuracy of data collection and reducing convenience pursuit should be implemented. Also as criteria to select a topic, different kinds of consulting concepts and taking social issues into consideration that helps tool development and analysis power should be done. Through varied methodologies, tool development and analysis power should be assisted and analysis unit should be shifted to organization unit for Korea and team or individual for China only to augment the accessibility. As a limitation for the paper is that the data used in this analysis is secondary data. In addition, although time period used in both countries were the same, object of analysis had homogeneity in Korean case while Chinese one having heterogeneity from 19 different journals. For the future studies, multicultural comparison or time series analysis and their comparison in deeper approach with regard to object of analysis and methodologies can contribute to further MIS diversity.

  • To detect individual vehicular speed, double loop detection technique has been widely used. This paper investigates four methodologies to measure individual speed using only a single loop sensor in a traveling lane. Two methods developed earlier include estimating the speed by means of (Case 1) the slop of inductance wave form generated by the sensor and (Case 2) the average vehicle lengths. Two other methods are newly developed through this study, which are estimations by measuring (Case 3) the mean of wheelbases using the sensor installed traversal to the traveling lane and (Case 4) the mean of wheel tracks by the sensor installed diagonally to the traveling lane. These four methodologies were field-tested and their accuracy of speed output was compared statistically. This study used Equality Coefficient and Mean Absolute Percentage Error for the assessment. It was found that the method (Case 1) was best accurate, followed by method (Case 4), (Case 2), and (Case 3).

  • Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone.

  • Based on my attendance at the CIPA International Symposium(CIPA2023) organized by the International Scientific Committee on Heritage Documentation(ICOMOS), this paper explored research cases applying digital technologies, including BIM, to architectural heritage. The researches presented at this symposium were categorized into specific areas: data acquisition, data management, data sharing&experience. Through this classification, an analysis of research cases in architectural heritage utilizing digital technology was conducted. By categorizing the 43 academic papers from the CIPA2023 based on research themes, trends in the digital architecture field were analyzed, providing insights into future research directions for the digital acquisition, management, sharing, and experiential aspects of Korean architectural heritage. In conclusion, it is deemed necessary to reference and supplement the methodologies, including algorithms, workflows, and approaches developed in each study, to effectively apply methodologies suitable for the characteristics of Korean architectural heritage and its data.

  • The domestic food industry intends to expand overseas market. In order to succeed, in-depth research on local consumers is essential. This paper examined consumer research methodology and case studies based on sensory and consumer science for developing products targeting overseas market. Consumer research should be prece ded by overseas consumer panel construction. Then, this can be followed by application of various consumer research methodologies on new product development process. The most important consideration in this case is that application of same research methods or criteria as for domestic market could lead to significant errors in terms of reliability of results. Therefore, in order to develop successful products that accurately meet the needs of overseas consumers, careful study and consideration of the differences between markets would be essential from consumer researcher and decision-maker's sides.

  • The purpose of this study is to develop an efficient exact algorithm for the problem of scheduling n in dependent jobs on m unequal parallel processors to minimize makespan. Efficient solutions are already known for the preemptive case. But for the non-preemptive case, this problem belongs to a set of strong NP-complete problems. Hence, it is unlikely that the polynomial time algorithm can be found. This is the reason why most investigations have bben directed toward the fast approximate algorithms and the worst-case analysis of algorithms. Recently, great advances have been made in mathematical theories regarding Lagrangean relaxation and the subgradient optimization procedure which updates the Lagrangean multipliers. By combining and the subgradient optimization procedure which updates the Lagrangean multipliers. By combining these mathematical tools with branch-and-bound procedures, these have been some successes in constructing pseudo-polynomial time algorithms for solving previously unsolved NP-complete problems. This study applied similar methodologies to the unequal parallel processor problem to find the efficient exact algorithm.
