Owing to the large number of video programs available, a method for accessing preferred videos efficiently through personalized video summaries and clips is needed. The automatic recognition of user states when viewing a video is essential for extracting meaningful video segments. Although there have been many studies on emotion recognition using various user responses, electroencephalogram (EEG)-based research on preference recognition of videos is at its very early stages. This paper proposes classification models based on linear and nonlinear classifiers using EEG features of band power (BP) values and asymmetry scores for four preference classes. As a result, the quadratic-discriminant-analysis-based model using BP features achieves a classification accuracy of 97.39% (${\pm}0.73%$), and the models based on the other nonlinear classifiers using the BP features achieve an accuracy of over 96%, which is superior to that of previous work only for binary preference classification. The result proves that the proposed approach is sufficient for employment in personalized video segmentation with high accuracy and classification power.

Purpose - The effect of regional culture has been acknowledged for decades. However, very little research takes it as an important issue in the medical tourism service decision process. This study focuses on regional culture to identify customers' preference for medical tourism in the international environment. It is proposed that regional culture may work as an critical moderator in the international medical tourism destination choice process. Especially, the destination attributes may vary according to regional culture. Research design, data, and methodology - By the questionnaire survey, the sample is collected from 2,041 potential Chinese residents in different regions of China. Regression analysis is constructed to test the effect of regional culture on Chinese customers' destination preference. Results - Results imply that regional culture plays a critical moderating role in the destination choice process. Results also indicate that destination attributes including medicine and travel characteristics are the important predictors of destination preference. Conclusions - This study provides the fundamental base to use regional culture as a descriptive variable for segmentation when establishing an effective marketing strategy. Furthermore, this research suggests that different strategies relied on destination attributes should be made to attract more Chinese customers for the development of medical tourism industry.

The purpose of this study is to develop the relationship model among subjective texture and preference of weft knit according to fiber contents of wool/rayon and loop length by integrating previous research work. SPSS and SEM method using AMOS program were used to analyze data which used to correlation matrix to be standardized. The texture of weft knit were classified into 4 categories: irregularity, flexibility, bulkiness, extensibility. The fiber contents of wool/rayon had effect positively on irregularity, bulkiness and extensibility and that had little effect on preference. The loop length had effect positively on irregularity, flexibility and extensibility and that had effect negatively on preference. This measurement model will be input for testing causal research model that can explain how fiber contents of wool/rayon and loop length of weft knit influence on subjective texture.

The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middle and high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.

In real life, a decision-maker can assign multiple values for pairwise comparison with a certain confidence level. Studies incorporating multi-choice parameters in multi-criteria decision-making methods are lacking in the literature. So, In this work, an extension of the Best-Worst Method (BWM) with multi-choice pairwise comparisons and multi-choice confidence parameters has been proposed. This work incorporates an extension to the original BWM with multi-choice uncertainty and confidence level. The BWM presumes the Decision-Maker to be fully confident about preference criteria vectors best to others & others to worst. In the proposed work, we consider uncertainty by giving decision-makers freedom to have multiple choices for preference comparison and having a corresponding confidence degree for each choice. This adds one more parameter corresponding to the degree of confidence of each choice to the already existing MCDM, i.e. multi-choice BWM and yields acceptable results similar to other studies. Also, the consistency ratio remained low within the acceptable range. Two real-life case studies are presented to validate our study on proposed models.

Functional, aesthetic and symbolic working uniforms in the industrial complex are demanded by employees and employers. The purpose of this research was to find out the actual wearing condition and preference of the working uniform design in the industrial complex. The research selected 7 enterprise subjects located in the Changwon National Industrial Complex and adopted a questionnaire method. 912 workers categorized into 4 work groups according to their work posts replied in total. The data and the degrees of satisfaction/preference of the working uniforms were analysed into descriptive statistics and F-tests by using the SPSS S/W package. The results were as follows: First, the style of the working uniform was the standard two-piece style. Second, the degree of the satisfaction with the entrepreneurial image implied to the working uniform was 2.83 throughout the 5-scale evaluation. In addition, the degree of the satisfaction with the working uniform colors was in between 2.94 and 2.96. Third, unsatisfied parts of the upper and lower uniform garments were: sleeve > pocket > collar; and waist belt loop > hip pocket > hem line respectively. Fourth, beige was the most preferred color for the working uniform top and bottom both. The most preferred color images were the calm and safety and the bright and light in order. Especially, the demand on the safety factors and soil proof colors of the outside field workers was much higher than the clerical workers. Fifth, the blouson type jacket with shirts collar or soutien roll collar was more preferred to than the casual style; and the straight formal pants were more preferred to than the casual/sweat sports pants styles. Sixth, inner pockets to keep the mobile phone and pens were required for upper garment details specially by manufacture workers. Increase of the waist belt loop numbers was required by all work groups.

In this paper, We focused the issue of creating a socially problematic nurse schedule. The nurse schedule should be prepared in consideration of three shifts, appropriate placement of experienced workers, the fairness of work assignment, and legal work standards. Because of the complex structure of the nurse schedule, which must reflect various requirements, in most hospitals, the nurse in charge writes it by hand with a lot of time and effort. This study attempted to automatically create an optimized nurse schedule based on legal labor standards and fairness. We developed an I/O Q-Learning algorithm-based model based on Python and Web Application for automatic nurse schedule. The model was trained to converge to 100 by creating an Fairness Indicator Score(FIS) that considers Labor Standards Act, Work equity, Work preference. Manual nurse schedules and this model are compared with FIS. This model showed a higher work equity index of 13.31 points, work preference index of 1.52 points, and FIS of 16.38 points. This study was able to automatically generate nurse schedule based on reinforcement Learning. In addition, as a result of creating the nurse schedule of E hospital using this model, it was possible to reduce the time required from 88 hours to 3 hours. If additional supplementation of FIS and reinforcement Learning techniques such as DQN, CNN, Monte Carlo Simulation and AlphaZero additionally utilize a more an optimized model can be developed.

The Purpose of this study is to analyze the impact of telecommuting-the use of telecommunications technology to perform work from remote sites- on the transportation system. It examined the effects of telecommuting on commuter travel. After reviewing case studies of foreign countries and their telecommuting characteristic, two types of survey, RP(Revealed Preference) and SP (Stated Preference), were carried out in order to analyze the impact of telecommuting on traffic. The RP survey examined respondents'attitudes toward information technology and the characteristics of their work. The SP survey asked respondents what conditions would make them want to become a telecommuter. It was found that higher salaries and communication subsidies would induce more people to telecommute. Overall, it was found that if telecommuting were to be executed in Seoul, 49.1% of workers would become telecommuters, which would result in a 14,407 billion won reduction in direct and indirect transport costs per year. This research proves that traffic congestion can be reduced effectively by instituting telecommuting as an option for workers.
