Objective: This study aimed to evaluate the immediate psychological effects of coordination exercises on women in Japan. Methods: The subjects were 17 adult women (height, 160.1 ± 5.1 cm;weight, 54.3 ± 10.5 kg;age, 57.8 ± 8.3 years) living in the community and attending a fitness club. The subjects performed a coordination exercise called Life Kinetik®. The subjects responded to the Two-Dimensional Mood Scale–Short Term before and after performing 30 minutes of Life Kinetik®. The results were tabulated and four psychological states were calculated (i.e., vitality, stability, pleasure, and arousal). The pre- and post-implementation results were statistically analyzed using a corresponding t-test. Results: Significant differences were found in activation and arousal levels, but not in stability and comfort levels. Conclusion: The coordination exercise, Life Kinetik®, was found to be an exercise program with potential psychological benefits, as it could change women’s psychological condition to active and excited states.

AIMTo elucidate the effect of antithrombotic therapy （ATT） on bleeding and thromboembolic complications during or after laparoscopic digestive *** articles or internationally accepted abstracts between 2000 and 2017 were searched from PubMed, Cochrane Database, and Google Scholar, and studies involving laparoscopic digestive surgery and antiplatelet therapy （APT） and/or anticoagulation therapy （ACT） were included after careful review of each study. Data such as study design, type of surgical procedures, antithrombotic drugs used, and surgical outcome （both bleeding and thromboembolic complications） were extracted from each *** published articles and two internationally accepted abstracts were eligible for inclusion in the systematic review. Only one study concerning elective laparoscopic cholecystectomy in patients with peri-operative heparin bridging for ACT showed that the risk of postoperative bleeding was higher compared with those without ACT. The remaining 14 studies reported no signifcant differences in the incidence of bleeding complications between the ATT group and the group without ATT. The risk of thromboembolic events （TE） associated with laparoscopic digestive surgery in patients receiving ATT was not signifcantly higher than those with no ATT or interrupted *** T et al . Laparoscopic digestive surgery and antithrombotic therapyCONCLUSIONLaparoscopic digestive surgery in ATT-burdened patients for prevention of bleeding and TE showed satisfactory results. The risk of hemorrhagic complication during or after these procedures in patients with continued APT or heparin bridging was not signifcantly higher than in patients with no ATT or interrupted APT.

The purpose of this paper is to estimate total factor productivity （TFP） growth in China by industry. As well as reviewing some previous studies on TFP growth in China, the authors present their estimation of TFP growth in China for two periods, 1987-1992 and 1992-1997. During both periods, output growth was as high as double digits. However, the differences in TFP growth between these two periods were remarkable. In the first period, wide-ranging TFP growth was observed, whereas in the latter period, high TFP growth was concentrated in industries such as ＂transportation equipment＂ and ＂electric machinery＂, which are known for actively introducing foreign capital and technologies. In fact, positive relations were confirmed among TFP growth, export performance, and the introduction of foreign capital. Foreign capital made a large contribution to China＇s exportled growth.
