  • 미생물 연구에서 대량의 마이크로바이옴 데이터를 효율적으로 얻는 기술이 발전해왔지만, 마이크로바이옴 빅 데이터를 적절하게 분석하는 도구는 여전히 부족하다. 또한 빈약한 데이터베이스를 사용하여 미생물 군집을 분석하면 잘못된 결과를 초래할 수 있다. 따라서 본 연구는 대량의 미생물 데이터베이스 분석을 위한 적절한 방법을 설계하고자 하였다. 박테리아는 개인의 손끝과 개인 소지품(휴대 전화 및 랩탑 키보드)에서 수집되었다. 박테리아로부터 게놈 DNA를 추출하고 16S rRNA 유전자를 표적으로 하여 차세대 시퀀싱을 실시하였다. 손끝과 개인 소지품 간의 박테리아 매칭 비율의 정확성은 공식과 함께 환경 및 인간관련 데이터베이스를 사용하여 확인하였다. 적절한 분석을 설계하기 위해 다음 세가지 범주를 기준으로: 정성적 분석과 정량적 분석 비교, 성별에 관계없이 모든 참여자뿐만 아니라 동일 성별 참여자 내 비교, 환경(eDB) 및 인간 관련 데이터 베이스(hDB)를 이용하여 샘플간 비교하였다. 결과는 정성적 분석과 동일 성별 참가자 내에서의 비교 및 hDB의 사용이 비교적 정확한 결과를 제공하였다. 우리의 연구는 인간 유래 미생물을 사용하여 대량의 미생물학적 데이터를 포함하는 연구를 수행할 때 정확한 결과를 얻을 수 있는 분석 방법을 제공한다.

  • 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.

  • 현재 남한의 해안선 길이는 일제시대 측량한 자료에 의하면 육지해안과 도서해안을 합하여 총연장이 약 11,542km에 달하는 것으로 알려져 있다. 해안선에 대한 정확한 자료를 얻기 위해 현지측량으로 이를 수정 갱신하게 되면 엄청난 예산과 시간이 소요될 것으로 추정되고 있다. 아울러, 공유수면 매립과 간척사업 및 신항만 건설 등 크고 작은 각종 개발사업으로 인해 연안해역과 해안선이 수시로 변화되어 연안해역도의 갱신작업이 빈번해지고 있어 현지측량에 대한 대안이 필요하다. 본 논문에서는 연구대상의 지역적 범위를 부산지역5개 해안(송도, 해운대, 광안리, 송도, 다대포 해안)으로 정하였고, RTK-GPS 측량을 실시한 뒤 정성적 분석과 3차원 지형분석을 실시하였다.

  • 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 the study was to identify and describe the caregiving difficulties that mothers of children with spina bifida experience from their own perspectives. Methods: A qualitative descriptive study was designed. Data were collected from five mini-focus group interviews and four individual interviews using open-ended questions. Nineteen mothers of children with mild spina bifida participated in the study during 2014-2015. Data were analyzed using qualitative content analysis to identify major difficulties perceived by the mothers. Results: Five domains were identified with 12 subdomains. "Daily routine continence management" describes difficulties arising in bladder and bowel management for the child with spina bifida. "Management of school life of child" deals with difficulties in relation to the school facilities, such as the toilets, as well as teachers and friends. "Relationship with family and neighbors" illustrates problems in relations with their spouse, normal children, relatives and neighbors. "Maintaining physical and psychological health" includes physical and psychological problems of the mothers. "Finance" describes economic burden that the mothers face in the management of child's illness. Conclusion: The findings from this study provide insight into the practical issues related to the management of chronic conditions of children with spina bifida from the mothers' perspectives.

  • 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.
