The experimental method, when carried out properly, is the most powerful way of seeking answers to research questions. The purpose of this study is to provide practical and theoretical insights as well as to discuss technical skills needed to design and implement the experimental research in library and information science. The levels of empirical research methods, the logic and types of the experimental designs, the application status of the experimental methods through content analysis of the published papers, and strategies to plan the research and to collect and analyze data are examined. This study also brings suggestions how experimental research can be made more meaningful and puts emphasis on the need of the research method education in library and information science field.

Purposes: The purpose of this study was to identify recent trends of experimental research by analyzing doctoral dissertations in all colleges of nursing in Korea. Methods: The areas of research, the content, methodological and intervention characteristics used in this study were explored in experimental research on doctoral dissertations (n=132) published from 2006 to 2010. Results: In the issues of research, practice/clinical issues were most frequently used. As to outcome measurement, physiological variables increased more than psychological/emotional variables. Most theory applied in the research was taken from other disciplines, and nursing theory was only Roy's adaptation theory. A large majority of the research was quasi-experimental designs and the number of true-experimental designs was very low. In more than half of the dissertations, internal validity was not described, and the described external validity rate was very low. There were more single intervention programs than bundle ones and education/exercise programs were most frequently used as the source of intervention. Conclusion: Doctoral dissertations need to increase and encourage more high quality experimental research to expand nursing knowledge and to develop evidence based nursing practice.

Purpose: The purpose of this study was to summarize trends and status of nursing research utilizing experimental designs in the Journal of Rheumatology Health over the past 10 years. Method: The Journal of Rheumatology Health published 37 experimental research articles between 1994 and 2004. These articles were included in a retrospective descriptive analysis. A checklist was utilized for data collection. Results: Qoasi-experimental researches were more frequent than pre-experimental research, but there were 8 research studies which had no hypothesis. The most frequently used nursing interventions were exercise/movement, and cognitive, followed by sensitive, and social interventions. There were very few research studies that used random assignment for internal validity. The rate of effectiveness of self-help interventions was lower than socio-psychological, cognitive, or motor-physical interventions. There was no research regarding families of patients with rheumatoid disease. Conclusion: Rigorous experimental research design is needed for internal and external validity in future research. Generalizing the effects of nursing interventions that are the results of rigorous experimental designs will contribute to promote the quality of life of patients with rheumatism and their families.

Objective : This study aimed to analyze a comprehensive feature of experimental research on Insamyangyoungtang and develop a strategy that can be used for experimental studies on Insamyangyoung-tang in the future. Method : The journal search was performed using six databases : PubMed, Chinese database (China Network Knowledge Infrastructure, [CNKI]), Japan database (Japan Science and Technology Information Aggregator, Electronic, [J-STAGE]) and three Korean databases (Oriental Medicine Advanced Searching Integrated System [OASIS], Research Information Service System [RISS], and Korean Studies Information Service System [KISS]). We used limited keywords and analyzed studies by publication year, experimental models, and the subjects of biological activities. The mechanism of pharmacological activity in accordance with the therapeutic effects of Insamyangyoung-tang was noted. Results and Conclusion : A total of 43 studies (6 domestic studies and 37 foreign ones) were examined according to the inclusion criteria of the experimental study. Research on the pharmacological activities of Insamyangyoung-tang showed its therapeutic effects on the nervous and immune systems, as well as its anti-aging, anti-fatigue, and hematopoietic effects. Additional efficacy and safety assessments and experimental and clinical studies should be performed to evaluate the mechanism of Insamyangyoung-tang. The present review has provided preliminary information for further studies on Insamyangyoung-tang.

Purpose: The purpose of this study was to identify the trend of research on the nursing research in the journal of rheumatology health and to suggest future perspective for nursing research. Method: In this study, we reviewed the contents of 131 researches published in this journal from its beginning year 1994 to year 2003. Result: In the 85.5% researches, type of the research subjects was patient. research that subject is patient' family was none. An analysis of the research design showed, non-experimental research was 67.2%, experimental research was 26.7%, qualitative research was 5.3%, triangulation research was only one. In the experimental design types of nursing intervention were movement intervention 38.4%, cognitive intervention 38.4%. and true experimental research was none. Among non-experimental researches, 93.2% was survey method, methodological research was two, concept analysis research was two, a-method was one. Conclusion: There has been a lack of qualitative research, true experimental research, research using vary nursing intervention. Further research need nursing intervention development that intervention can be use in actual nursing care area.

Purpose: The objective of this study is to analyze systematically the trends of experimental researches in the area of community health nursing. Methods: This is a study based on literature review, which analyzed 137 experimental research papers in the Journal of Korean Academy of Community Health Nursing, from the first issue in 1989 to those in 2012. Results: 1) The proportion of experimental researches in the total published papers was 14.9%. 2) The mainly used research method was quasi-experiment, which was 60.6% of them, and there was no RCT. 3) Convenient sampling was used in 95.6% of the researches. 4) Only 5.1% were reviewed for keeping the ethical standards for the study objects by the IRB. 5 When classified by the Omaha Classification System, psycho-social researches were most frequent, which were followed by physiological, health-related behavioral, and environmental ones in order of frequency. Conclusion: This study found that the proportion of experimental research papers was increasing in the 2000s and ethical standards were required more rigorously. However, it was suggested that the research design be more elaborated and sampling methods be manifested to reduce research bias and errors.
