Qualitative research methodology has been applied with increasing frequency in various fields, including in healthcare research, where quantitative research methodology has traditionally dominated, with an empirically driven approach involving statistical analysis. Drawing upon artifacts and verbal data collected from in-depth interviews or participatory observations, qualitative research examines the comprehensive experiences of research participants who have experienced salient yet unappreciated phenomena. In this study, we review 6 representative qualitative research methodologies in terms of their characteristics and analysis methods: consensual qualitative research, phenomenological research, qualitative case study, grounded theory, photovoice, and content analysis. We mainly focus on specific aspects of data analysis and the description of results, while also providing a brief overview of each methodology's philosophical background. Furthermore, since quantitative researchers have criticized qualitative research methodology for its perceived lack of validity, we examine various validation methods of qualitative research. This review article intends to assist researchers in employing an ideal qualitative research methodology and in reviewing and evaluating qualitative research with proper standards and criteria.

The possibilities of non-linear analysis of reinforced-concrete structures are under development. In particular, current research areas include structural analysis with the application of advanced computational and material models. The submitted article aims to evaluate the possibilities of the determination of material properties, involving the tensile strength of concrete, fracture energy and the modulus of elasticity. To evaluate the recommendations for concrete, volume computational models are employed on a comprehensive series of tests. The article particularly deals with the issue of the specific properties of fracture-plastic material models. This information is often unavailable. The determination of material properties is based on the recommendations of Model Code 1990, Model Code 2010 and specialized literature. For numerical modelling, the experiments with the so called "classic" concrete beams executed by Bresler and Scordelis were selected. It is also based on the series of experiments executed by Vecchio. The experiments involve a large number of reinforcement, cross-section and span variants, which subsequently enabled a wider verification and discussion of the usability of the non-linear analysis and constitutive concrete model selected.

세계적으로 해양산업은 크루즈산업에 많은 관심과 연구가 대폭적으로 이루어지고 있고 우리나라도 미래의 잠재력 있는 국가동력산업의 하나로 인식하고는 있으나 크루즈산업의 연구동향 분석 연구는 국내외에 활발히 이루어지고 있지 않다. 따라서 우선 세계 크루즈산업을 연구하고 이해하기 위해서는 최근에 다양한 산업에 대한 연구동향을 분석한 방법을 활용하여 크루즈산업에도 적용할 필요가 있다. 본 논문의 목적은 외국 유명저널에 발표된 크루즈산업과 관련된 학술논문에서 제시하고 있는 키워드와 논문을 매개로 한 키워드 네트워크를 구축하여 복잡계의 네트워크 분석에서 사용하는 연결 중심성과 매개 중심성 분석방법으로 시대별로 나누어 시각화하여 살펴봄으로써 세계 크루즈산업의 연구동향을 심층적으로 관찰하여 논의하는 것이다. 본 연구에서 제시된 키워드 빈도는 Zipf의 법칙을 따르고 노드의 연결정도는 멱함수 분포를 보여주고 있어 언어네트워크에서 분석하는 키워드 네트워크와 동일함을 관찰한다. 연구방법론으로는 키워드 네트워크 분석을 위하여 사회연결망 프로그램인 넷마이너 4.0을 사용하여 여러 가지 중심성 측정방법 중 키워드 상위 20개의 빈도순위를 비교하여 빈도순위와 가장 가까운 중심성 측정방법을 선택하여 크루즈산업의 연구동향을 분석한다. 특히 크루즈산업의 연구동향이 연도 기간별로 어떠한 변화를 가져왔는지를 살펴보기 위해 2000년 이전과 2000년 이후로 크게 대별하여 나누고 2000년 이후에는 5년 주기로 각 기간별 공통적으로 나타나는 연결 중심성이 높은 최상위의 키워드인 cruise와 tourism 노드를 중심으로 매개 중심성이 높은 것들의 키워드 네트워크를 시각화하여 논의한다. 연구결과에서 흥미롭게도 2010-2014의 기간에 새로운 노드로 China가 등장하여 최상위의 키워드들을 연결하고 있는 것은 최근 급성장하고 있는 중국의 크루즈산업의 발전 양상을 보여준다. 그러므로 본 연구에서 사용하는 키워드 네트워크 분석은 각 연도 기간별 네트워크의 다른 종류의 숫자와 크고 작은 중심축 군집 네트워크의 숫자의 증감뿐 아니라 중심축 군집 네트워크의 중심에 있는 키워드 간의 연결 분석을 용이하게 해주어 기간별 연구동향을 파악하는데 유용한 방법임을 확인할 수 있었다.

The object of this article is to assess the factors affecting the behavioral intention of young retail customers to use digital banking services in Vietnam. In this article, multivariate data analysis techniques including Cronbach's Alpha, Exploratory factor analysis (EFA), Confirmatory factor analysis (CFA), Structure equation model (SEM), and Bootstrapping are used to analyze the data collected from 525 young respondents under the age of 35 who are using or having opportunities to experience digital banking services. The people taking part in the survey were mainly University students with incomes of most of them under VND 5 million. The result from the analysis illustrates that (1) perceived ease of use positively affects intention to use, (2) social influence positively impacts intention to use, and (3) customer support has a positive impact on the intention of young people to use digital banking services. While technology self-efficacy, convenience, and perceived security were found to have an impact on intention to use services in former studies, the influences of these factors on intention to use digital banking services are found insignificant in this research. From these results, the author provides implications for commercial banks to increase the intention to use digital banking of young people in Vietnam.

Objectives : The aim of this review was to summarize and assess researches reporting thermal properties of moxibustion. Methods and Materials : We searched one electronic database(PubMed) and two journals(The Journal of Korean Medicine and The Journal of Korean Acupuncture & Moxibustion Society) and for the articles published until Nov. 2012. The articles reporting thermal characteristic of moxibustion were selected and reviewed. 31 articles were included and assessed in this review. The type of moxibustion, the material beneath moxbustion, main outcome and the amount of information were reviewed. The amount of information was defined as 1 for one main outcome reported in each article. Results : Direct moxibustion were used in 15 articles and indirect moxibustion were used in 19 articles. 11 researches used anti-heating plate for the material beneath moxibustion, one article used steel ring, agar with anti-heating plate, six articles used skin and another six articles used heater. Two articles used animals and another two articles used metals. The mean value of the amount of information was $4.41{\pm}2.94$(SD). Conclusions : Research articles assessing properties of moxibustion have been consistently published since 1993, and employed various methodologies. The amount of information has been associated with four section analysis and is currently decreasing. Research assessing properties of moxibustion with clinical effectiveness is needed.

This article identifies factors affecting successful ERP systems by focusing on the stages after stabilizing ERP systems and overcoming temporary performance dip by introduction of ERP systems, and suggests change management tactics to control those identified factors. We can not expect that every users are familiar with the usage of an ERP system even after they are informed about the expected advantage of the newly implemented ERP system and trained intensively for changed business process and system usage while implementing a new ERP system. Moreover, even after more than six months usage of the system, the users may still have some trouble due to the reason why they have insufficient information about the expected advantage of the system (recognition gap) and insufficient knowledge about the changed usage of the system (knowledge gap). Hence, this article diagnoses by conducting a case study that those recognition and knowledge gap would have a severe bad influence upon the users' trust and satisfaction on ERP systems. This article suggests an appropriate change management tactics to overcome those recognition and knowledge gap by considering the relationship with the efforts for change management before, during, and after the introduction of ERP systems and performing an in-depth analysis on the users' dissatisfaction and request for update during the stages after the stabilization of the ERP systems. This article also shows a corroborative evidence that these efforts of change management consequently contributes to the solution of users' distrust and dissatisfaction. In sum, this article identifies the factors influencing badly on the magnitude and seriousness of knowledge and recognition gap, and suggests a conceptual research model which says that the satisfaction of ERP users could be uplifted by the solution of their knowledge and recognition gap if we keep making efforts on appropriate change management considering those identified factors during the stages after the stabilization of an ERP system.

Due to the nature of fashion design that responds quickly and sensitively to changes, accurate forecasting for upcoming fashion trends is an important factor in the performance of fashion product planning. This study analyzed the major phenomena of fashion trends by introducing text mining and a big data analysis method. The research questions were as follows. What is the key term of the 2010SS~2019FW fashion trend? What are the terms that are highly relevant to the key trend term by year? Which terms relevant to the key trend term has shown high frequency in news articles during the same period? Data were collected through the 2010SS~2019FW Pre-Trend data from the leading trend information company in Korea and 45,038 articles searched by "fashion+material" from the News Big Data System. Frequency, correlation coefficient, coefficient of variation and mapping were performed using R-3.5.1. Results showed that the fashion trend information were reflected in the consumer market. The term with the highest frequency in 2010SS~2019FW fashion trend information was material. In trend information, the terms most relevant to material were comfort, compact, look, casual, blend, functional, cotton, processing, metal and functional by year. In the news article, functional, comfort, sports, leather, casual, eco-friendly, classic, padding, culture, and high-quality showed the high frequency. Functional was the only fashion material term derived every year for 10 years. This study helps expand the scope and methods of fashion design research as well as improves the information analysis and forecasting capabilities of the fashion industry.
