Objectives: The focus of the analysis was laid on changes in research pertaining to bee venom in regards to time progression. Methods: We collected 365 articles on Bee venom study result from OASIS system using the Keyword ``bee venom, apitoxin, apitherapy, bee sting``. We figured out number and percentage of theses according to year, study method, journal, subject. Results: Bee venom papers published in the journal of korean medicine from 1976. The classification of papers associated with bee venom, clinical studies outnumbered the other study types by a ratio of 1.3 to 1, followed by 138 for experimental papers, and 22 for literature studies. Proportion of Experimental Papers Classified According to the Theme, 16 for pain-killing, 14 papers concentrated on apoptosis, anticancer, 13 for anti inflammatory, 11 for arthritis, and other disorders were followed. Type analysis of papers associated with bee venom in clinical trials, lumbar disorders comprised 38 out of 205 papers, 35 papers concentrated on upper limb disorders, 34 papers concentrated on systemic disease, followed by the effect on body. Conclusions: Bee venom is a treatment method based on the unique theory of Korean traditional medicine. Its effort and academical approach on bee venom are expected to receive positive evaluation through numerous research works.

This paper investigates cutting qualities after laser dicing and predicts the problems that can be generated by laser dicing. And through 3 point bending test, die strength is measured and the die strength after laser dicing is compared with the die strength after mechanical sawing. Laser dicing is chiefly considered as an alternative to overcome the defects of mechanical sawing such as chipping on the surface and crack on the back side. Laser micromachining is based on the thermal ablation and evaporation mechanism. As a result of laser dicing experiments, debris on the surface of wafer is observed. To eliminate the debris and protect the surface, an experiment is done using a water soluble coating material and ultrasonic. The consequence is that most of debris is removed. But there are some residues around the cutting line. Unlike mechanical sawing, chipping on the surface and crack on the back side is not observed. The cross section of cutting line by laser dicing is rough as compared with that by mechanical sawing. But micro crack can not be seen. Micro crack reduces die strength. To measure this, 3 point bending test is done. The die strength after laser dicing decreases to a half of the die strength after mechanical sawing. This means that die cracking during package assembly can occur.

ObjectivesWe will provide basic information on bee venom clinical tests and aid the practical use of bee venom in such tests, through examination of RCT research related to bee venom that was reported domestically. MethodsWe collected 365 articles on Bee venom study result from the OASIS system using the Keyword ‘bee venom, apitoxin, apitherapy, bee sting’. The initially selected theses were primarily screened for clinical research. Out of these, case studies and non randomized controlled trial (non-RCT) were ruled out. As a result, 39 studies of randomized controlled trial (RCT) research were chosen as the subjects of study. ResultsRCT research related to bee venom was first presented in 2003, and 39 studies have been published until 2012. 18 studies were tests to confirm the effectiveness of bee venom, 7 studies were comparisons between SBV and BV, and 13 studies were comparisons with other types of treatment. Research conducted through appropriate randomization methods were 20 studies, and inappropriate randomization methods were used in 19 studies. In therms of Jadad score, 12 studies received 4~5 points, 15 studies received 1~3 points, and 12 studies received zero point. ConclusionsIn order to assure good quality RCT research, appropriate guidelines should be provided, and proper evaluation standards should be established. In-depth study is needed concerning the difference of responses to treatment according to the types of treatment received. A standardization of treatment should be reached as a result.
