Purpose: This study was to determine the current trend of nursing research as exploring both quantitative and qualitative methodologies, and to provide the explicit direction to improve the quality of published papers. Methods: Total of 366 articles published between 2004 and 2006 was reviewed using the criteria of analysis. Results: There was more number of quantitative studies than qualitative studies. More studies were conducted with subjects who had health problems, and studies that targeted women and elderly population have been significantly increased. In quantitative methodology, utilization of experimental and quasi-experimental designs has been increased, however descriptive study was dominant as yet. In qualitative methodology, studies using grounded theory and phenomenology were frequently published. It was noted that theoretical framework and rational for sample size were rarely presented in quantitative study. Philosophical position and the process of preparation for study, which guided the research, were not clearly described in qualitative study. Conclusion: The findings of this review suggest that published studies have been improved and diversified, however, detailed and clear evaluation tool that assesses study process and method should be developed as a way to further improve the quality of published papers.

How to measure technological level has concerned research analysists for a long time. Many methods exist, and they all have their advantages and disadvantages according to how they are used. The purpose of this study is to develop qualitative indicator to measure industrial technological level, in particular manufacturing capacity. In this indicator, the two basis of technology classification and the concept of the technology competitiveness were introduced. First, the types of technology are classified as three classes : material technology, processing technology and product technology. Second, the characteristics of technology are divided into the three categories : core technology, peripheral technology and sprouting technology On this basis, the qualitative technological level was made in terms of the competitiveness of it's manufacturing capacity. This study should be a practical approach for application of measuring of technological level.

Objectives: The study was performed to investigate job-seeking stress for university students who have a major in healthcare. Methods: For the analysis, 10 fourth-year students who are willing to get a job were interviewed. Interviews were conducted from October 2011 to November 2011 for 2 weeks. The data were collected with semi-structured open-ended questions and analysed by the method of Consensual Qualitative Research(CQR). Results: The main reasons for the job-seeking stress for students were insufficient preparation for getting a job, uncertainty, anxiety, pressure, and age. A reinforcing factor for stress was family. Conclusions: Universities should provide educational, psychological, and economic supports to job-seeking students majoring healthcare because of their relatively fewer opportunities for getting a job compared to those who have a major in non-healthcare.

In quantitative contexts, data mining is widely applied to the prediction of stock prices from financial time-series. However, few studies have examined the potential of data mining for shedding light on the qualitative problem-solving knowledge of experts who make stock price predictions. This paper presents a GA-based data mining approach to characterizing the qualitative knowledge of such experts, based on their observed predictions. This study is the first of its kind in the GA literature. The results indicate that this approach generates rules with higher accuracy and greater coverage than inductive learning methods or neural networks. They also indicate considerable agreement between the GA method and expert problem-solving approaches. Therefore, the proposed method offers a suitable tool for eliciting and representing expert decision rules, and thus constitutes an effective means of predicting the stock price index.

Objectives: The study was performed to investigate job training stress for university students who have a major in healthcare. Methods: For the analysis, 11 fourth-year students who have experienced job training at healthcare-related agencies were interviewed. Interviews were conducted from May 2016 to June 2016 for 3 weeks. The data were collected with semi-structured open-ended questions and analysed by the method of Consensual Qualitative Research(CQR). Results: The main reasons for the job training stress for students fell into two personal and environmental domains. And the domains were analyzed by 12 categories in-depth. Students felt stress by tasks, personal relationship, and burden of duties. Conclusions: To deal with job training stress, students took emotional and behavioral treatments such as positive thinking, communication, and so on. Universities should provide sufficient information on the characteristics of training agencies and training programs to lighten the stress for students.

Purpose: Tinnitus, which is often described as the conscious awareness of a sound without an external auditory stimulus, is one of the most common symptoms in the general population. This study aimed to explore the experiences of individuals living with tinnitus. Methods: In this qualitative exploratory study, data were collected from November 2017 to January 2018 through in-depth individual interviews with 11 tinnitus patients. Verbatim transcripts and field notes were analyzed using content analysis. Results: The extracted content was classified into three core categories of tinnitus experiences: "suffering from constant sound," "being imprisoned surrounded by persistent noise," and "efforts to overcome." Conclusion: This study shows that tinnitus had a severe negative impact on patients' lives. The finding will help healthcare providers understand their patients more deeply.

This paper presents a model and algorithm for solving the multi-factor plant layout problem. The model can incorporate more than two factors that may be either quantitative or qualitative. The algorithm is based on simulated annealing, which has been successfully applied for the solution of combinatorial problems. A set of problems previously used by various authors is solved to demonstrate the effectiveness of the proposed methods. The results indicate that the proposed methods can yield good quality for each of eleven test problems.

Purpose: This study attempted to describe the essential structure of nursing students' experiences as observers of human body dissection. Methods: The research was undertaken as qualitative research. The data was collected through written sources of 169 students majoring in nursing. The analysis of data was made using the phenomenological analytic method suggested by Colaizzi (1978). Results: In this study, five categories of themes emerged. They were: 'unfamiliar wait','standing at the edge of chaos','growth through reflection', 'be immersed in practice', 'winging to be a nurse'. Conclusion: This study will prove helpful not only in understanding nursing students' observation experiences of human body dissection but also in describing their needs for systematic and emotional support.
