There are some limitations in the existing bibliometric methods to satisfy the various requests of the interest parties including researchers, managers, policy makers to identify 1) which research group or researcher is the key player, and the overall trends of the particular technological sub-fields, 2) which research groups, institutions or countries mainly use their research outputs, 3) what are the spin-offs from research outputs to some scientific and technological fields, 4) in which levels they are when comparing their quantitative and qualitative research outputs to those of other competitive institutions. It is essential to develop new informetric indicators and methodologies in order to satisfy stakeholder's various demands and to strengthen qualitative analysis in measuring research performance. This study suggested informetric indicators such as article quality index, citation impact index, international cooperation index, excellent article production index and methodologies including citation analysis, text mining.

Objectives : The results from randomized controlled trials on traditional medicine have been negative or ambiguous. The appropriateness of the research methodology started to be questioned. However, the research methodology appropriate for studying traditional medicine has not been well-established. This study aims to explore the appropriate research methodologies for clinical studies on acupuncture. Methods : Clinical researches evaluating the efficacy and effectiveness of acupuncture for back pain were systematically searched and evaluated focusing on research methodology. The acupuncture treatment protocol is evaluated by 9 items which is individual treatment based on diagnosis, combining proximal and distal acupoints, exact location of acupoint, De Qi, adequate stimulation, duration of acupuncture, treatment sessions, treatment interval, and establishing relationship between patients and doctors. Results : Systematic review of acupuncture researches on low back pain suggested that observational studies and pragmatic trials rather than explanatory studies could incorporate these elements. Qualitative studies also could help understanding complex characteristics of acupuncture treatment which could not be evaluated by quantitative studies. Conclusions : In designing clinical researches on acupuncture, various study designs, especially observational study and pragmatic study, should be considered according to research objectives and subjects. The efforts to incorporate the core characteristics of acupuncture practiced in everyday clinical setting are also essential.

The paper discusses application of soft OR methodologies, which have been developed for last decades centered in European OR communities, to strategy formation process. It is shown that there is strong similarity in understanding of strategy formation between descriptive school of strategy and the research trend of soft OR. The focus and philosophical background of cognitive school of strategy, in particular, share much in common with soft OR school. The analysis and overview of several soft OR methodologies are introduced. It is also proposed that SODA can be utilized more directly to the strategy formation process. However, it is also noted in this paper that the epistemological issues should be considered and resolved for fluent investigation of soft OR methodologies in relation with existing rich strategic research works, for soft OR adopts interpretative research methods while strategy research generally lies on positivistic approaches.

Purpose: The goal of this study was to identify the current status of research on job stress conducted in Korea and to suggest directions for future nursing research. Methods: A total of 395 articles (76 nursing science, 100 health science, 219 social science) selected from 'Korean Research Foundation Registered Journals' were reviewed. The papers were classified by criteria, focusing on research frameworks, topics and methodologies. Results: There has been a rapid increase in the number of articles since the 1990s. However, the following issues were discovered: lack of theoretical frameworks about factors related to job stress, a paucity of attention to sophisticated methodologies including the development of strong measurement tools, and incoherence among the level of theory, level of measurement, and/or level of statistical analysis. Conclusion: Based on the key findings of this study the following are proposed: increased efforts to develop theoretical framework to guide empirical investigations, improvements in methodological rigor, research conduct with various job groups with different approaches such as qualitative or experimental research, and encouragement for interdisciplinary approaches to the study on job stress.

We propose a series of methodologies that can evaluate relative efficiency of logistics units(centers) in three categories; managerial, cost, and operational efficiency. Inputs and outputs of logistics systems are first defined. Appropriate quantitative and qualitative measures for the three categories are then selected. Employed also are Analytic Hierarchy Process, Weighted Scoring Method, Stochastic Frontier Model, and Data Envelopment Analysis for the development of a comprehensive assessment scheme. Our scheme not only assesses the degree of relative efficiency of logistics units but also identify the sources of inefficiency in each unit The methodologies are applied to a large telecommunications company which operates 12 distribution centers nation wide. Relative efficiencies of the centers are compared using 1995-1997 performance data. Summarized are the level of efficiency of each distribution center for each of the three categories. The degree and sources of inefficiency of each distribution center are also discussed.
