  • The purpose of this study is to introduce the concept of community resilience to rural society and build an index suitable for the reality of rural areas. Furthermore, by calculating the importance of evaluation factors, it was attempted to present priorities and alternatives for each evaluation factor. By stratifying the derived indicators, a survey was conducted targeting 20 researchers, practitioners, and public officials, three groups of experts working in rural areas who were well aware of the realities and problems of rural areas. In the survey, a pairwise comparison was performed to compare factors 1:1 to calculate the importance, and for rational and consistent decision-making, decisions were made in the 9-grade section. Using the collected data, consistency analysis that can evaluate reliability in the decision-making process and the relative weight of evaluation factors were calculated through AHP analysis. As a result of the analysis, as a result of examining the priority of final importance by summarizing the importance of all evaluation factors, 'Income creation using resources' > 'Population Characteristics' > 'Tolerance' > 'External Support' > 'Social Accessibility' > 'Physical Accessibility' > 'Community Competence' > 'Infrastructure' > 'Leader Competence' > 'Natural Environment' was derived in the order. In the study dealing with urban community resilience indicators, social aspects such as citizen participation, public-private cooperation, and governance were presented as the most important requirements, but this study differs in that the 'income creation' factor is derived as the most important factor. This can be seen through the change in the income difference between rural and urban areas. The income structure of rural areas has changed rapidly, and it is now reaching a very poor level, so it is necessary to prepare alternatives to 'income creation' in the case of rural areas. Unlike urban indicators, 'population characteristics' and 'tolerance' were also derived as important indicators of rural society. However, there are currently no alternatives to supplement the vulnerability by strengthening the resilience of rural communities. Based on the priority indicators derived from the study, we tried to suggest alternatives necessary for rural continuity in the future so that they can be supplemented step by step.

  • The purpose of this study was to analyze usage frequency and importance of competencies which are required to restaurant industry professionals. For this purpose, opinions of restaurant industry professionals on the competency were surveyed using questionnaires. To develop a questionnaire, a total of 27 competency variables which are required to restaurant industry professionals were drawn through literature review. Questionnaires were distributed to 300 professionals in restaurant industry with different positions using random sampling. Out of 300 questionnaires, 221 questionnaires were used for analysis. Statistical analysis was conducted using SPSS 10.0, including descriptive analysis, ANOVA and t-test. Reliability test and factor analysis were also conducted to evaluate the reliability and validity of the questionnaire. As a result, 'attitude and personality' factor was recognized as the most frequently used and the most important competency factor of restaurant industry professionals. Therefore, the competency such as 'sincerity', 'responsibility', 'sense of honesty', 'positive attitude', 'tolerance and justice', should be more emphasized in restaurant management education. The level of current usage and importance of each competency were different according to age, education level, working experience, position, number of employees, type of restaurant and type of management.

  • Business analysis is a key factor of project success or failure in information systems. However, there are few studies on business analysis competencies. The objective of this paper is to identify which competencies a business analyst (BA) needs, and analyze the importance weights and priorities of business analysis competencies. Literature review yielded 6 competency dimensions and 30 competencies. Based on interviews with 12 experts and analytic hierarchy process analysis, the relative importance weight and priority of each business analysis competency were analyzed. Moreover, an importance-perception gap between stakeholders in different positions was identified. This result can be used as selection and development criteria for superior BAs that are responsible for solving business problems using information systems solutions.

  • Food is widely accepted as very important factor in tourists' experiences by researchers. However, few studies revealed tourists' importance of food for their travel. Therefore, through a case study in Busan (South Korea), this study aims to critically assess the importance of food tourism from domestic tourists' perspectives. In particular, this study assess the relationship between food tourists' value, nutrition information, behavioral intention of tourists' food experiences during their travel. Using SmarPLS program, a quantitative research methodology involving a structured questionnaire has been adopted. The results reveal that food tourists' value and importance of nutrition information plays different roles in food tourism. Food tourism value and nutrition information has shown its importance for increasing revisit intention in Busan. In light of these findings, marketing strategies can be identified to accelerate the development of food tourism at a destination.

  • Purpose: The purpose of this study was to investigate the importance of nurses' caring behaviors and to identify the factors influencing of nurses' caring behaviors. Methods: The participants were 404 nurses who were caring the chronically sick elderly in five H university hospitals. Data were collected through self-reported questionnaires on the importance of caring behaviors, nursing professional value and job satisfaction. Data were analyzed with descriptive statistics, t-test, ANOVA, Scheffe-test, Pearson's correlation coefficient and stepwise multiple regression with SPSS/WIN 16.0. Results: The average score for importance of nurses' caring behaviors was 3.38 and the 'professional knowledge and skill' factor was the highest level. The mean score of nursing professional value was 7.53 and job satisfaction, 3.18. Importance of nurses' caring behaviors had a significant positive correlation with nursing professional value, job satisfaction, nurse's age and work experience among demographic variables. Two significant variables influencing importance of nurses' caring behaviors were nursing professional value and job satisfaction. But characteristics of nurses did not influence. Conclusion: The findings of this study indicate that importance of nurses' caring behaviors can be improved by intervening factors affecting this importance. Based on the findings of this study, further nursing practice and nursing research for nurses caring the sick elderly should be focused on their nursing professional value and job satisfaction.

  • In this paper, the importance of input factors of a DNN (Deep Neural Network) PM2.5 forecasting model using LRP(Layer-wise Relevance Propagation) is analyzed, and forecasting performance is improved. Input factor importance analysis is performed by dividing the learning data into time and PM2.5 concentration. As a result, in the low concentration patterns, the importance of weather factors such as temperature, atmospheric pressure, and solar radiation is high, and in the high concentration patterns, the importance of air quality factors such as PM2.5, CO, and NO2 is high. As a result of analysis by time, the importance of the measurement factors is high in the case of the forecast for the day, and the importance of the forecast factors increases in the forecast for tomorrow and the day after tomorrow. In addition, date, temperature, humidity, and atmospheric pressure all show high importance regardless of time and concentration. Based on the importance of these factors, the LRP_DNN prediction model is developed. As a result, the ACC(accuracy) and POD(probability of detection) are improved by up to 5%, and the FAR(false alarm rate) is improved by up to 9% compared to the previous DNN model.
