In this study, we propose a methodology for predicting the movie audience based on movie information that can be easily acquired before opening and effectively distinguishing qualitative variables. In addition, we constructed a model to estimate the number of movie audiences at the time of data acquisition through the configured variables. Another purpose of this study is to provide a criterion for categorizing success of movies with qualitative characteristics. As an evaluation criterion, we used information gain ratio which is the node selection criterion of C4.5 algorithm. Through the procedure we have selected 416 movie data features. As a result of the multiple linear regression model, the performance of the regression model using the variables selection method based on the information gain ratio was excellent.

Purpose: The purpose of this study is to present a preferred parts list, establish a search tool for common parts, and propose a development plan for parts management. Methods: When selecting the preferred parts list, the weight of the selection of the military parts and the online site of the civilian parts were taken into account. By establishing a database of selected preferred parts list, we have established a system for searching common parts. Results: The results of this study are as follows; In order to establish parts management work in Korea's defense, it is necessary to improve the Defense Acquisition Program Act, Enforcement Decree (Rules), and the Regulations for Defense Acquisition Program Administration. Development of performance indicators for parts management is required, and establishment of procedures and standards for selection of preferred parts lists is required. Considerations for the selection of preferred parts list include whether they are used a lot in civilian products, whether they are used a lot, whether they are certified suppliers, whether they are national and industrial standard products, whether they perform well considering reliability, durability, and quality, and whether they can be supplied continuously. Conclusion: It is necessary to establish policies and systems related to parts management and to establish criteria for selecting preferred parts list for the development of domestic parts management tasks.

The purpose of this study is to analyze the difference of educational institutions and majors on Learning Participatory Motivation of Lifelong Education Organizations of Universities and Job Technical Colleges that are operating academic degrees on bachelor of fashion and associate of industrial arts in Academic Credit Bank System. The significance of this study is to provide basic information for educational institutions to promote efficient operation and devise a strategy for reinforcing educational competitiveness according to individual Learning Participatory Motivation and purpose of learners. In this study, educational institutions were classified into Lifelong Education Organizations of Universities and Job Technical Colleges operating academic degrees in Academic Credit Bank System. Degrees were divided into bachelor of fashion and associate of industrial arts, and majors were divided into fashion design and fashion business for bachelor of fashion and fashion design and fashion business for associate of industrial arts. Looking at Learning Participatory Motivation of learners, factors selected by learners as considerations for registration and selection of currently affiliated educational institution were found to be 'acquisition of degree at a university' and 'acquisition of degree' for Lifelong Education Organizations of Universities and fashion design major, and 'for employment' and 'acquisition of new knowledge and skill' for Job Technical Colleges and fashion business major.

The progress is widely used as a critical index for successful construction project management. In spite of the importance of progress measurement, the excessive management effort to collect and maintain detailed data has been highlighted as a major barrier to measurement of highly accurate progress. In order to reduce the required workload and to enhance accuracy, several researches have been conducted. These researches can be categorized into two groups. First group focuses on automated data collection utilizing advanced technologies only for limited construction tasks. The second group is a research area where the standard progress measurement methodologies encompassing entire construction tasks are investigated. Topics include the adjusting the level of details, standardizing work processes, and applying flexible WBS. However, the techniques for automated data collection are not fully investigated yet in the second group. Combining these two research areas can provide a solution for more effective progress management in terms of enhancing accuracy and optimizing workload. However, there has been no comprehensive research addressing these two research groups in an integrated manner. In this context, the purpose of this paper is to propose a methodology that identifies the most suitable measurement method and data acquisition technology (e.g., GPS, RFID, etc.) for entire construction tasks of a project. The proposed methodology in this paper will be able to facilitate the selection process of data acquisition technologies for entire construction tasks of a project and to support the overall enhancement of automated progress management.

This study analyzed the factors that influence menu choices through eye-tracking and questionnaires in menu design. Demographic data of subjects coincided with choosing a menu and eye-tracking data. Hot Crispy Chicken Burger is the most popular menu. The study found that regardless of the selected menu, the menu name (35.5 seconds), price (21.6 seconds), and image (16.0 seconds) were viewed the longest, followed by country of origin (8.81 seconds), calories (4.6 seconds), and special indications (p<0.05). The menu name and image were checked more frequently, while calorie information was checked less often. As a result of analyzing various factors that influence menu selection through, Consumer experience and image greatly influenced menu choices. Therefore, if you want to receive a menu selection, it is considered effective to make good use of the menu name and image. In results of principal component analysis (PCA) by gender showed. Men had the longest price in the fixation duration. But, for females, there was a significant difference in gaze fixation when they took the exam, with menu names and special indications being important selection criteria. Since the results show that selection criteria and information acquisition methods differ depending on gender, this research is thought to be able to suggest directions for menu design.

Objectives: The purpose of this study was to investigate the factors of importance in the medical field from the perspective of the consumer, using "Consumption Life Indicators in Korea." Methods: We examined the general characteristics, economic conditions, information acquisition, complaint-provoking experiences, cognitive score on dispute resolution, and factors affecting medical domain importance selection, using SAS 9.4. software. Results: It was found that "age" among general characteristics and "income" among economic conditions were important factors in selecting medical domain importance. Thus, it was possible to reaffirm the poor health of socioeconomically vulnerable people and their socioeconomic difficulties. Conclusions: The medical domain selection group needs the attention of the government, medical institutions, academia, consumer groups, community service groups and professional organizations, and needs substantial economic support and customized education.
