The carmine spider mite, Tetranychus cinnabarinus (Boisduval), is a serious phytophagous mite damaging importantcrops and can rapidly develop resistance to acaricides. Mitochondrial ATP synthase (F1F0 ATP synthase)is an important target site of acaricides. The role of ATP synthase in acaricide resistance remains unclear at themolecular level. In this study, twelve full-length cDNAs of ATP synthase genes were cloned and characterizedfrom T. cinnabarinus and their expression levels were determined for both progargite-resistant and susceptiblestrains. The effect of propargite exposure on gene expression was also evaluated. Analyses of gene expressionrevealed that TcATPsynU-2, TcATPsynF0-2 and TcATPsynF0-4 were significantly down-regulated in the progargite-resistant strain. TcATPsynF0-2 and TcATPsynF0-4 had a strong response to progargite exposure. Theresults suggest that lower levels of TcATPsynU-2, TcATPsynF0-2 and TcATPsynF0-4 expression might be related topropargite-resistance observed in the resistant T. cinnabarinus. This is the first attempt to identify specific ATPasegenes involved in propargite resistance in T. cinnabarinus.

This study is attempted to research on the factor of flexibility and Touch of Handspring, and measures 12 sophomore students on Department of physical Education in Won Kywang Univ. The results of this study are as follows; 1. It is the best point 30cm(8.92points) of Touch the others(0cm∼7.92, 15cm∼8.48) 2. There are the more shorter of Touch-distance the more higher Correlation of the factor of flexibility (0cm∼0.64, 15cm∼0.49, 30cm∼0.42) 3. Bending to left (0cm∼0.74, 15cm∼0.54, 30cm∼0.52) is the higher correlation the other on the factor of flexibility and each Touches. 4. There are significance on increasing results in Touching on the analysis of Variance. 5. There are significance on increasing results in exercising on the analysis of Variance.

This paper addresses a study of inner-tank sloshing effect on motion responses of a Floating Liquefied Natural Gas (FLNG) system, through experimental analysis and numerical modeling. To investigate hydrodynamic characteristics of FLNG under the conditions of with and without LNG-tank sloshing, a series of numerical simulations were carried out using potential flow solver SESAM. To validate the numerical simulations, model tests on the FLNG system was conducted in both liquid and solid ballast conditions with 75% tank filling level in height. Good correlations were observed between the measured and predicted results, proving the feasibility of the numerical modeling technique. On the verified numerical model, Response Amplitude Operators (RAOs) of the FLNG with 25% and 50% tank filling levels were calculated in six degrees of freedom. The influence of tank sloshing with varying tank filling levels on the RAOs has been presented and analyzed. The results showed that LNG-tank sloshing has a noticeable impact on the roll motion response of the FLNG and a moderate tank filling level is less helpful in reducing the roll motion response.

This study aims to explore the potential use of ultrasound in locating the second posterior sacral foramen acupuncture point, quantifying depth of insertion and describing surrounding anatomical structures. We performed acupuncture needle insertion on a study team member. There were four steps in our experiment. First, the acupuncturist located the acupuncture point by palpation. Second, we used an ultrasound machine to visualize the structures surrounding the location of the acupuncture point and measure the depth required for needle insertion. Third, the acupuncturist inserted the acupuncture needle into the acupuncture point at an angle of 30°. Fourth, we performed another ultrasound scan to ensure that the needle was in the desired location. Results suggested that ultrasound could be used to locate the acupuncture point and estimate the depth of needle insertion. The needle was inserted to a depth of 4.0 cm to reach the surface of the sacral foramen. Based on Pythagoras theorem, taking a needle insertion angle of 30° and a needle insertion depth of 4.0 cm, the estimated perpendicular depth is 1.8 cm. An ultrasound scan corroborated the depth of 1.85 cm. The use of an ultrasound-guided technique for needle insertion in acupuncture practice could help standardize the treatment. Clinicians and students would be able to visualize and measure the depth of the sacral foramen acupuncture point, to guide the depth of needle insertion. This methodological guide could also be used to create a standard treatment protocol for research. A similar mathematical guide could also be created for other acupuncture points in future.
