  • Although technological advances have allowed the efficient collection of large amounts of microbiome data for microbiological studies, proper analysis tools for such big data are still lacking. Additionally, analyses of microbial communities using poor databases can lead to misleading results. Hence, this study aimed to design an appropriate method for the analysis of big microbial databases. Bacteria were collected from the fingertips and personal belongings (mobile phones and laptop keyboards) of individuals. The genomic DNA was extracted from these bacteria and subjected to next-generation sequencing by targeting the 16S rRNA gene. The accuracy of the bacterial matching percentage between the fingertips and personal belongings was verified using a formula and an environment-related and human-related database. To design appropriate analysis, the bacterial matching accuracy was calculated based on the following three categories: comparison between qualitative and quantitative analysis, comparisons within same-gender participants as well as all participants regardless of gender, and comparison between the use of a human-related bacterial database (hDB) and environment-related bacterial database (eDB). The results showed that qualitative analysis, comparisons within same-gender participants, and the use of hDB provided relatively accurate results. This study provides an analytical method to obtain accurate results when conducting studies involving big microbiological data using human-derived microorganisms.

  • This paper is a qualitative and quantitative study. The main purpose of the paper is to diagnose what makes English communication difficult at the Korean EFL adult level. In order to obtain data, this study employed interviews and a questionnaire. We identified thirty three factors blocking pathways to oral communication. Qualitative analysis repeatedly revealed patterns such as lack of grammar, lack of vocabulary, lack of background knowledge, and peer pressure, but quantitative analysis yielded somewhat different results: lack of colloquial expressions, lack of vocabulary, lack of various topics, problems in the educational system, difficulty in using existing knowledge, and lack of grammar. Findings which were common to both qualitative and quantitative analyses suggest that lack of linguistic knowledge and lack of background knowledge are major barriers learners encounter in communication. On the basis of the results, suggestions are made for overcoming these barriers.

  • This paper takes a qualitative approach to examining liveability by analysing the participatory planning proposals delivered by the local residents in Daegu, South Korea. Drawing on the textual resources of the proposals and interview data, the perceived liveability was found to vary across different neighbourhoods, and community cohesion and community capacity building were found highly valued in the liveability discourses in the Korean context. The paper argues that our understandings of liveability should be localised and contextualised at a sub-municipal level. It also highlights that participatory planning can be useful in articulating local communities' perception and experiences of liveability of their immediate localities, particularly in the less attractive and less affluent neighbourhoods in the city.

  • In this paper, we present new methods for identifying keywords for foresight topics that utilize the internet and textmining techniques to draw objective and quantified information that support experts' qualitative opinions and evaluations in foresight. Furthermore, by applying this fabricated procedure, we have derived keywords to analyze priorities in architectural engineering. Not much difference between qualitative methods of experts and quantitative methods such as text mining has been observed from comparison between technologies derived via qualitative method from "The Science Technology Vision" (control group). Therefore, as a quantitative tool useful for drawing keywords for foresight, textmining can supplement quantitative analysis by experts. In addition, depending on the level and type of raw data, text mining can bring better results in deriving foresight keywords. For this reason, research activities accommodating Internet search results and the development of textmining methods for analyzing current trends are in demand.

  • Purpose: This article was proposed to describe and summarize the following 1) the structural hierarchy of nursing knowledge and 2) the four different methods of concept analysis and concept development, which are used most frequently in nursing literature, and 3) to demonstrate a qualitative data synthesis of situation-specific theories in Korea in order to provide an venue for developing Korean-contextualized nursing theory. Methods: A literature review and a meta-synthesis were used. An interpretive integration method for the meta-synthesis was used to incorporate incorporating the results of ten qualitative studies in Korea. Results: The normative and extended concept of the self was one of the three foremost concepts. The experiences of being detached from a group and of being unlike others were perceived with distress to Korean participants. Lastly, as a coping method, complying with a higher flow or power was used. Conclusion: Based on the three concepts elicited in this article, a substantive theory which withholds Korean nursing concepts and essences is hoped to be developed in future.

  • According to the survey data during the Japanese Occupation Period, the length of South Korea's coastline is about 11,542 km, including the coastlines of land and islands. It will be very expensive and time-consuming to revise/renew accurately this coastline data through site survey, it will cost great money and time. Also, various development projects such as reclamation works on public waters, constructions of ports/harbors, etc. are frequently changing the coastal areas and coastlines, causing many renewal projects on coastal maps. For such reason, appropriate alternatives for site survey are necessary. This paper demonstrate the utilization of RTK-GPS survey data, qualitative analysis and 3D topographic analysis for extracting the change in five coastal areas (Songjeong, Haeundae, Kwanganri, Songdo and Dadaepo). The local experimental areas subjected for this research were limited to five coastal areas near Busan.

  • Background: In Iran, there are high rates of breast cancer. It is among the five most common cancers, the first among cancers diagnosed, and is the leading cause of cancer deaths among Iranian women. Objectives: The purpose of this qualitative study was to explore perception of breast cancer screening among Iranian women who have never had a mammograph. Materials and Methods: The current study was part of a qualitative research conducted by means of content analysis method and purposive sampling of 16 women over the age of 30 years who had not undergone mammography using individual semi-structured interviews. Interviews were recorded and transcribed verbatim. The data were under continuous consideration and comparative analysis in order to achieve data saturation. Results: After codification of data, three concept categories were achieved including: i) low awareness, ii) worries, and iii) lack of motivation. Conclusions: Although there is a tendency among Iranian women to participate in breast cancer screening, there is a powerful cultural belief that breasts are sexual organs that should not be discussed publicly. Due to the incidence of breast cancer in Iranian women, it is critical that breast awareness education be performed by health care experts to explore the concepts of breast cancer and breast cancer screening.

  • Purpose: The purpose of this study was to investigate the experience of horizontal violence in intensive care unit (ICU) nurses. Methods: This is a methodological triangulation study consists of quantitative and qualitative research methods. A total of 134 ICU nurses from 5 hospitals participated in a survey on nurse to nurse horizontal violence, and the qualitative data were collected through 3 focus group interviews. Results: 94.0% of the participants have experienced horizontal violence within the past 6 months. The question with the highest mean score was "dominating senior nurses mood", and the question with the lowest mean score was "physical assaults". The qualitative data analysis revealed 17 themes on the backgrounds, types, and influence of horizontal violence. Conclusion: The survey result shows that the problem of horizontal violence in ICU nurses is serious, and the focus group interview extracts additional types of horizontal violence such as "scolding in a wrong way", "pressing to resign", "leaving out in the cold", and "burning". Further research needs to be done to build a multidimensional model of horizontal violence in the nursing workplace.
