Objectives: Breast cancer patients in Korea need to care about symptoms with complementary medicine including acupuncture. We reviewed the randomized controlled studies using acupuncture in breast cancer patients to establish a basic knowledge of clinical practice guidelines. Methods: We searched the following databases through July 2015: the Cochrane Central Register of Controlled Trials, Ovid-Medline, Ovid-EMBASE, the Allied and Complementary Medicine Databases and OASIS. The articles of RCTs using acupuncture in breast cancer for all symptoms were selected and analyzed. The acupoints, treatment period, inclusion criteria of participants, follow-up period and effectiveness were extracted. Results: Three hundred fifty five records after duplicate were screened, and 14 RCTs were selected. RCTs of Hot flush, pain, fatigue were reviewed. The adverse symptoms using medical treatment in breast cancer patients were targets of acupuncture in RCTs. The acupuncture treatment was decreased the hot flush, pain and fatigue. However, the effect was not confirmed due to various study design. Conclusions: The analysis of the research would be conjugated to establish a basic knowledge of clinical practice guidelines. Well designed studies in Korea are needed to confirm the efficacy and safety of acupuncture in patients with breast cancer.

BSR(Buzz, squeak and rattle) is the key factor that makes decision of quality of product, which should be eliminated and various efforts for that have been done by developer. Especially, unlike the conventional methods that are done after production such as adding tapes or sponges, some recent techniques have been focused on predicting BSR at design stage using finite element method. In this study, methods to detect rattle based on the frequency response analysis(FRA) are introduced, which are applied on simple structure composed of two cantilever beams and results are compared with that from simulation. In addition, probabilistic approaches are developed to consider the variation that parameters used for FRA have. More efficient probabilistic analysis techniques including response surface and sensitivity analysis are used to reduce computational costs, which are carried out on numerical example to determine their validity by comparing with Monte-Carlo simulation. Program to conduct procedure of probabilistic analysis is established using MATLAB, which can be used for NASTRAN limitedly.
