  • We survey 3,857 journal articles published on the four domestic academic journals in the industrial engineering field during 1975~2012. Titles, abstracts, and keywords of the papers are searched by means of text mining technique to draw the information on the methodologies and techniques adopted in the papers, and then we aggregate and merge similar ones to obtain final 38 representative methodologies and techniques. Trends of these methodologies and techniques are studied by analyzing frequencies, clustering, and finding association rules among them. Results of the paper can shed a light to choose tools in the future education and research in the industrial engineering related area.

  • Objective : To make comprehensive feature of previous researches on moxibustion, then build a basis of strategy for development of moxibustion-derived therapeutics. Methods : Surveyed 326 abstraction-containing literatures from total 467 of moxibustion-related papers in PubMed and 29 papers in Korea. Analysis was performed according to distribution by study subject, number by year, nation, research method, and its efficacy. Results : Moxibustion-related researches have been rapidly increased since 2001. The main contributive country for moxibustion research was China whileas few researches was done by Korea. The main subjects of moxibustion research are associated with immunity, inflammation, neurosystem, and digestive function. The most therapeutic roles of moxibustion were on pain control, modulation of immunity, anti-fatigue and anti-stress. Conclusion : This study will help Korean Oriental medical doctors to systematically review the moxibustion researches, and to develop more competitive therapeutics using moxibustion in global CAM field.

  • Objectives: The purpose of this study was to review the studies of the wild ginseng complex pharmacopuncture related to obesity treatment. Methods: We searched the papers with key words of 'wild ginseng complex pharmacopuncture', 'wild ginseng pharmacopuncture', 'obesity', 'fat', 'weight' in Oriental medicine Advanced Searching Integrated System, KRpia, Koreanstudies Information Service System, Research Information Sharing Service, KoreaMed and PubMed, Scopus. We classified the papers by year, content and study type. Results: There were 7 studies about the wild ginseng pharmacopuncture related to obesity treatment. Cell studies were excluded because they were not related to obesity. Analysis of 3 animal experiments and 4 clinical studies were conducted to describe each research subject, method, and research results. Conclusion: More interest and further research will be needed on wild ginseng pharmacopuncture related to obesity treatment in the Korean medicine to achieve clinical application and to develop treatment protocols for the obesity disease.

  • Since its first appearance in the late 1970s and early 1980s, executive information system (EIS) has been reported to improve executives' productivity in line with the rapid growth of the EIS market. In this paper, we aim to provide both researchers and practitioners with a comprehensive bibliography on EIS. this bibliography consists of papers which were extracted from (1) INSPECT commercial database service, (2) previous surveys in books and journals, and (3) major conference proceedings. A total of 227 papers, published between 1983 and 1992, were identified and categorized by topic, and journal or conference. The major findings indicate that EIS has been widely used in both profit oriented organizations and non-profit oriented organizations and that the nature of system has been the most active topic among the researchers and practitioners. However, the survey suggests that further research should be focused on development and implementation methodologies of EIS, especially requirement analysis and EIS planning.

  • This study investigates the effects of online English writing instruction on university students' writing performance and their anxiety. A total of 34 participants completed the pre- and post- writing tests as well as the surveys regarding perceived anxiety toward English writing. Reflection papers and interviews were employed to triangulate the results of the questionnaires. Quantitative analysis of learners' writing outcomes and surveys revealed that online writing instruction helped improve students' writing skills and reduce writing anxiety. The interviews and reflection papers demonstrated that learners found the writing instruction helpful in reducing somatic anxiety, avoidance behavior, and cognitive anxiety. The current study suggests that adopting non-face-to-face online writing instruction aids EFL students in developing their writing and alleviating writing anxiety.

  • Evidence-based papers on the treatment of some chronic tendinopathy or ligament lesions using an injection in foot and ankle disorders have been reported, but there are few reports on the treatment of acute ankle ligament injury. On the other hand, some papers have reported a faster return to play for injection therapy that combines RICE (Rest, Icing, Compression, and Elevation) treatment and rehabilitation. Injection therapy can be used as an additional treatment for ankle ligament injury. Rather than having narrow-minded thinking about these treatments, it is important to make efforts to verify the safety and precautions of treatment and recognize them as a category of normal treatment. Continuous analysis and monitoring of these treatments can satisfy patients whose needs are changing rapidly.

  • This study is concerned with suggesting a new clustering algorithm to evaluate the value of papers which were supported by research grants by Korea Research Fund (KRF). The algorithm is based on an extended version of a conventional PSO (Particle Swarm Optimization) mechanism. In other words, the proposed algorithm is based on integration of k-means algorithm and simulated annealing mechanism, named KASA-PSO. To evaluate the robustness of KASA-PSO, its clustering results are evaluated by research grants experts working at KRF. Empirical results revealed that the proposed KASA-PSO clustering method shows improved results than conventional clustering method.
