This study aims to provide philosophical frameworks and approaches, and practical guidelines to interview research. While there are some studies which focus on the practical guidelines, there is a lack of studies which address the philosophical and conceptual issues integral to qualitative interview research. By discussing three different but related philosophical aspects of qualitative interviewing--phenomenology, hermeneutics, and dialectics--consistency among research purpose, research method, research methodology is pursued. Based on this discussion, four stages of interviewing--designing, conducting, analyzing, and writing of qualitative interview research--are presented.

Many enterprises are interested in using the IS development methodologies as a means of increasing system performance and solving the problems of delayed delivery time, excessive budget, and failure of integrated systems. Even if previous researches showed that the system productivity and quality improvement using the system development methodologies are very poor, we tried to find that the methodologies are meaningful as an innovative means for IS performance. We defined that the IS development methodology as a technical and managerial innovation for IS department. We intended to study the relationship between the implementation process of the IS development methodology divided into four steps and IS performance. A cross-sectional field survey with IS departments of domestic companies was conducted, and we used LISREL 8.12a to perform the structural equation model analysis and hypothesis verification. We found the meaningful relationship between the development methodology and qualitative performance. We reconfirmed that the relationship between the development methodology and quantitative performance is not meaningful as expected, which is the same result with the previous researches. But the qualitative performance affects very strongly to the quantitative performance. As a results, we suggest that IS managers and developers keep the principles of the IS development methodologies to get the quantitative performance through the qualitative performance improvement.

본 연구에서는 단순한 구간대신에 구간내에 제한된 형태의 가능성 분포를 갖 는 복합구간으로 학장하는 것이다. 그리고 이러한 가능성 분포는 퍼지 집합이론에서 사용되는 것처럼 일반적인 분포형태 전체를 사용하는 것이 아니라, 가능성 분포의 무 게중심만 정의하고 이 무게중심과 구간경계만을 사용하여 시스템 변수가 갖는 정성값 을 나타낸다. 이를 바탕으로 새로운 상태변화와 그 규칙을 정의함으로써 정성 모델 링과 시뮬레이션을 할 수 있는 정성 수학을 공식화하였다.이와 같은 방식으로 구한 정성 모델과 추론방법으로 기존의 논문에 나와 있는 시뮬레이션 결과와 비교하여 본 논문에서 제시한 정성해의 논리적 건전성(soundness)을 보였다.

1998년 과천시 ITS 시범사업을 시작으로 현재까지 ITS와 관련된 수많은 사업들이 시행되고 있으며, 시행되는 사업에 대한 타당성 평가를 위해 정량적 및 정성적인 효과분석이 시행되고 있다. 그러나, ITS와 관련된 업무의 공통적인 기준을 제시하기 만들어진 ITS 업무요령에서도 정성적인 조사 및 분석방법론에 대한 체계적인 내용이 부족하다. 정성적인 조사 및 분석결과는 편익화하기는 어려우나, 이용자 측면의 조사 및 분석은 ITS사업의 현실적인 효과 및 구축목표의 도달성을 직접적으로 판단할 수 있는 장점이 있다. 따라서, 본 논문에서는 정성적인 조사 및 분석 방법론 수립의 필요성 검토는 물론, 정성적인 조사계획 수립 및 실시, 데이터분석, 그리고 최종적으로 효과를 분석하고 개선방안을 도출하는, 전체적인 방법론을 정립하였다. 향후 이를 통해 ITS 사업의 평가에서 정량적인 측면과 정성적인 측면의 적절한 균형을 유지하게 되어, 보다 정확하고 효율적인 ITS 사업의 효과분석이 지속적이고 체계적으로 이루어질 것으로 보인다.

In this paper, we dealt with substantial asset analysis methodology applied to two-dimensional asset classification and qualitative evaluation method according to the business process. Most of the existent risk analysis methodology and tools presented classification by asset type and physical evaluation by a quantitative method. We focused our research on qualitative evaluation with 2-dimensional asset classification. It converts from quantitative asset value with purchase cost, recovery and exchange cost, etc. to qualitative evaluation considering specific factors related to the business process. In the first phase, we classified the IT assets into tangible and intangible assets, including human and information data asset, and evaluated their value. Then, we converted the quantitative asset value to the qualitative asset value using a conversion standard table. In the second phase, we reclassified the assets using 2-dimensional classification factors reflecting the business process, and applied weight to the first evaluation results. This method is to consider the organization characteristics, IT asset structure scheme and business process. Therefore, we can evaluate the concrete and substantial asset value corresponding to the organization business process, even if they are the same asset type.

Purpose: Ethical behaviors become more salient when researchers utilize face-to-face interviews and observation with vulnerable groups or communities, which may be unable to express their emotions during the sessions. The present research aims to investigate ethical behaviors while conducting research have resonance due to the deep nature of observation and interview data collection methods. Research design, data and methodology: The present research obtained non-numeric (Textual) data based on prior literature review to investigate Ethical Conducts in Qualitative Research. Non-numeric data differs from numeric data in how the data is collected, analyzed and presented. It is important to formulate written questions and adopt them what the method claims for the researcher to understand the studied phenomenon. Results: Our findings show that while conducting qualitative research, researchers must adhere to the following ethical conducts; upholding informed consent, confidentiality and privacy, adhering to beneficence's principle, practicing honesty and integrity. Each ethical conduct is discoursed in detail to realize more information on how it impacts the researcher and research participants. Conclusions: The current authors concludes that five ethical conducts are important for realizing extensive and rich information during qualitative research and may be exploited in implementing research policies for researchers utilizing observation and interviews methods of data collection.

In supply chain management, supplier capacity is very important to meet the customer demand quickly. This paper studies a supplier evaluation structure and then suggests a methodology using fuzzy theory for selecting an effective supplier. Several quantitative and qualitative evaluation factors should be analyzed in the evaluation structure. The qualitative factors includes not only product and service qualities but financial condition. The methodology deals with both the quantitative and qualitative factors together through fuzzy inference. A case study is also presented to show how to choose the best one among potential suppliers.

Purpose The purpose of this study is to identify the determinants of non-use and the dynamic nature of non-use by the qualitative research methodology, grounded theory methodology, as part of identifying the nature of non-use. Design/methodology/approach We applied the grounded theory methodology to a total of 23 college students, including non-users who are not currently using them, users with low intention to use them, and users with high intention to use. We extracted the codes related to the use and proposed the non-use dynamics conversion process based on the coding results. Findings First, the use of information technology can also promote the frequency of use, but can also lead to the use of negative attitudes which would fall in the state of non-use. Second, the user may have both positive and negative attitudes toward the current information technology. Third, if usage is dominated by habits, it is not so easy to change persistent use into an unused state. Fourth, factors that determine the use of specific information technology can be a factor in determining nonuse. This study has contributed to understand the essence of non - use as well as the nature of use, overcoming limitations of quantitative research approach and confirming possibility of grounded theory method in information system research.

The purposes of the present article are to suggest pragmatism as offering a philosophical paradigm for mixed methods research, to explain the fundamental principles of mixed methodology, and to present examples of research for understanding how to apply it to family studies. Mixed methods research is the class of research where the researcher mixes or combines quantitative and qualitative techniques, methods, approaches, concepts or language into a single study. Mixed methodology has its roots in pragmatism, which is a new philosophical paradigm to criticize the traditional dualism and to endorse eclecticism and pluralism. The present article argues that mixed methods research has the potential to answer a broader and more complete range of research questions, and to provide strong evidence for a conclusion through convergence and corroboration of the qualitative and the quantitative methods.
