  • Today, facilities are composed of many complex components or parts. Because of this characteristics, the frequency of failures is decreasing, but the strength of failures is increasing; therefore, the failure analysis about many complex components or parts was needed. In the former research about Fault Tree Analysis, failure data of similar facilities have been used for forecasting about target system or components, but in case that the system or components for forecasting failure is new or qualitative and quantitative data are given simultaneously, there are many difficulty in using Fault Tree Analysis with this incorrect failure data. Therefore, this paper deal with the Fault Tree Analysis method which be applied with Fuzzy theory in above case. In case that , therefore, if there is no the correct failure data, it is represented a system or components as qualitative variable. subsequently, it converted to the quantitative value using fuzzy theory, and the values used as the value for failure forecast.

  • Purpose: In the highly competitive franchise market, the perceived entrepreneurial passion and emotions of customers are very important, because it impacts on the success of companies. Thus, the purpose of this paper is to suggest how the impact of the franchise entrepreneurial passion and positive emotions on the brand trust and loyalty of customers. Research design, data and methodology: This study analyzes data was collected through questionnaires on customer(n=480) who had visited franchise restaurants. Analysis of used collected data was based on the mix method using quantitative and qualitative comparative analysis. Results: The quantitative analysis results showed inventing passion, developing passion, positive emotions that perceived by customers have a positive impact on brand trust. On the other hand, founding passion did not have an impact on loyalty in quantitative analysis. but when combined with developing passion in qualitative comparison analysis, but when combined with developing passion in qualitative comparison, that became the sufficient condition of high loyalty of customers. Conclusions: The franchisor of the Korean franchise industry is indiscriminately overusing the founding franchisees, causing social problems. In this situation, founding passion can have a negative impact on customers. Therefore, the franchisors must have management capabilities by strictly managing the founding rules of the franchisee and disclosing the corporate vision.

  • The focus of this study is to represent a methodology of analysis for integrated logistic system by means of the Evolution Strategies and Data Envelopment Analysis(DEA). The integrated logistic system is composed of AS/RS (Automated Storages and Retrieval System), AGVs(Automated Guided Vehicle System) and Conveyor System. We design the simulation alternatives with choosing the qualitative critical factors for the each subsystem. Evolution Strategies is used to optimize the quantitative critical factors and responses of each alternative. DEA is applied to measure the efficiency of the alternatives in order to select the optimal operation efficiency scheme. The method of analysis which combines Evolution Strategies with DEA can be used to analyze the qualitative and quantitative critical factors in the integrated logistic systems.

  • Purpose: The purpose of this qualitative research was to investigate chronically ill patients' perception of hospital nurses. Methods: Individual in-depth interviews and qualitative content analysis were used for data collection and analysis respectively. Participants were 13 chronically ill hospitalized patients or outpatients in three universities hospitals. All interviews were recorded and transcribed verbatim. Data were analyzed using the qualitative content analysis suggested by Graneheim and Lundman (2004). Results: Three themes emerged from the 10 sub-themes, which were categorized from the 21 condensed meaning units by interpreting the underlying meanings. The three themes were "person giving comfort and support by caring", "person facilitating the process of healing", and "person taking the initiative in power relations". Two themes involved positive experiences of patients and the other included negative ones. Conclusion: The results showed that the participants perceived the hospital nurses as devoted to caring for patients and facilitating treatments, but authoritative in performing their duty. Based on these results, it is recommended that hospital nurses improve their nursing knowledge, skills and humanistic attitude.

  • Purpose: The purpose of this study is to compare and analyze the enterprise's score index calculated from atypical data and corrected data. Research design, data, and methodology: In this study, news articles which are non-financial information but qualitative data were collected from 2,432 SMEs that has been extracted "square proportional stratification" out of 18,910 enterprises with fixed data and compared/analyzed each enterprise's score index through text mining analysis methodology. Result: The analysis showed that qualitative data can be quantitatively evaluated by region, industry and period by collecting news from SMEs, and that there are concerns that it could be an element of alternative credit evaluation. Conclusion: News data cannot be collected even if one of the small businesses is self-employed or small businesses has little or no news coverage. Data normalization or standardization should be considered to overcome the difference in scores due to the amount of reference. Furthermore, since keyword sentiment analysis may have different results depending on the researcher's point of view, it is also necessary to consider deep learning sentiment analysis, which is conducted by sentence.

  • This paper introduces a branch of qualitative method, called an in-depth interview method. By collecting data from the stories of Korean middle school students and a 9th grade American girl who used Geometer's Sketchpad and various software respectively for their mathematical problem solving, the qualitative analysis leads us to understand how such software affect their lives with mathematics subject. The unique characteristics and strands of each student's utterances reflect how software plays a role of learning aid for their mathematics learning. The arm of this study is both to get a good picture of each student's self-perceived relationship to mathematics as well as to explore external and objective parameters and factors in each student's internal situations. The qualitative descriptions of the collected data help us guide the students to the points where they could develop their interests and satisfaction with subject matter better. In this way, teachers may have more realistic understandings of how students become interested and motivated by mathematics, so that they are better able to find out ways of grasping the totalities of how the use of technology is interwoven into the school curricular.

  • The purpose of this study was to investigate the relationship between the quantitative analysis of biomechanical movement and the qualitative analysis of video software in order to evaluate for the walking movement. The fourteen collegiate students who agreed with the purpose and method of this study participated as subjects. The slow walking and fast walking of the subjects in the place of experiment were photographed, and calculated several mechanical factors. This empirical evidence from the experiment indicated the significant difference(p<.001) between each distant factors of the walking movement for both analyses methods, but there was no statistically significant difference between the spacial factors observed in the experiment. For more detail, no significant difference between the walking ratios that expressed the coordination between stride length and stride frequency was found. The findings also indicated the high coefficient of correlation(over r=.9) which supports higher explanation force for the biomechanical method and the Dartfish video software method. Therefore, if the data was gathered by using the proper experimental method, the video software method could be used just like the quantitative data of biomechanical method.
