The purpose of this research was the comparative study of 3 kinds of black soybean on murine immune cells. The 3 kinds of black soybean are Glycine max Merr. with inner color-yellow (GY), Glycine max Merr. with inner color-greenish (GG) and Rhynchosia volubilis Lour. (RV). All of the black soybean increased the viability of murine thymocytes in vitro. The combined treatment of GY or GG and mitogen did not affect the viability of splenic T- and B-lymphocytes compared with mitogen-treated group, but the combined treatment of RV and mitogen increased their action compared with mitogen-treated group. Also, the 3 kinds of black soybean were given p.o. once a day for 7 days, respectively. RV increased the population of thymic-$CD8^+$, splenic-$CD8^+$ and $B220^+$ cells in vivo. Furthermore, GY and GG did not affect the phagocytic activity and the production of nitric oxide in peritoneal macrophages in vitro, but RV enhanced their action. These results suggest that immunopotentiative action of Rhynchosia volubilis Lour. is more potent than their of Glycine max Merr.

In order to investigate the pharmacological action of the combined preparation of crude drugs, 'Saengkankunbi-Tang' were studied. These studies were conducted in an attempt to investigate the effect of 'Saengkankunbi-Tang' on activities of the liver enzyme, protein contents and the excretory action of bile juice in the serum of $CCl_4-intoxicated$ rabbits. The results of this investigate were summarized as follows; GOT, GPT activities and total cholesterol contents in the serum of rabbits induced by $CCl_4$ were shown to the remarkable decrease with the passage of the time in the oral administration of the sample. Albumin contents in the serum of rabbits induce by $CCl_4$ were noted to the significant increase with the passage of the time. Serum total protein contents were noted to the significant increase only the 4th and 6th day. BSP accumulation contents in the serum of rabbits induced by $CCl_4$ showed the remarkable decrease with the passage of the time.

This paper suggests the new technology to control metal flow in order to reduce the number of preforming and the machining for the cold forged product with complex geometry. This technology is the combined forming that consists of bulk and sheet forming with double action dies. To analyze the process, finite element simulation has been performed. The proposed technology is applied to hub model that is part of air conditioner clutch. The purpose of this study is to investigate the material now of hub through the relative-velocity control of punch and mandrel using the flow control forming technique.

We report a 29-year old female who developed bilateral femoral neuropathy combined with multiple abscesses in both thigh muscles. She was present with weakness in both lower extremities for 15 days and intermittent chilling sense for 3 months. Nerve conduction study showed complete absence of compound muscle action potentials in bilateral femoral nerves when stimulated at inguinal area. Electromyographic examination revealed no motor unit action potentials in both rectus femoris and vastus medialis muscles. CT revealed multifocal abscesses in bilateral thigh muscles. After antibiotic treatment, the patient's neurologic symptoms were improved.

In order to further improve the accuracy and time efficiency of behavior recognition in intelligent monitoring scenarios, a human behavior recognition algorithm based on YOLO combined with LSTM and CNN is proposed. Using the real-time nature of YOLO target detection, firstly, the specific behavior in the surveillance video is detected in real time, and the depth feature extraction is performed after obtaining the target size, location and other information; Then, remove noise data from irrelevant areas in the image; Finally, combined with LSTM modeling and processing time series, the final behavior discrimination is made for the behavior action sequence in the surveillance video. Experiments in the MSR and KTH datasets show that the average recognition rate of each behavior reaches 98.42% and 96.6%, and the average recognition speed reaches 210ms and 220ms. The method in this paper has a good effect on the intelligence behavior recognition.

Experiments were performed to explore the hysteretic performance of steel reinforced concrete (SRC) cross-shaped columns. Nine specimens were designed and tested under the combined action of compression, flexure, shear and torsion. Torsion-bending ratio (i.e., 0, 0.14, 0.21) and steel forms (i.e., Solid - web steel, T - shaped steel, Channel steel) were considered in the test. Both failure processes and modes were obtained during the whole loading procedure. Based on experimental data, seismic indexes, such as bearing capacity, ductility and energy dissipation were investigated in detail. Experimental results suggest that depending on the torsion-bending ratio, failure modes of SRC cross-shaped columns are bending failure, flexure-torsion failure and torsion-shear failure. Shear - displacement hysteretic loops are fuller than torque - twist angle hysteretic curves. SRC cross-shaped columns exhibit good ductility and deformation capacity. In the range of test parameters, the existence of torque does not reduce the shear force but it reduces the displacement and bending energy dissipation capacity. What is more, the bending energy dissipation capacity increases with the rising of displacement level, while the torsion energy dissipation capacity decreases.

The extract of Mawhang-tang showed considerable inhibition of 70.7 and 57.2% at oral doses of 200 and 400mg/kg, respectively, on carrageenin edema in rat paw. In case of combined oral administration of the extract at each dose of 100, 200 and 400mg/kg with 100mg/kg of aspirin, the inhibition percentages were 78.2, 87.2 and 72.5%, respectively. The combined oral administration of 200mg/kg of the extract with 200mg/kg of aspirin exhibited 87.6% inhibition of the edema. On the writhing syndrome induced by 0.7% acetic acid solution, the oral administration of 200mg/kg of the extract with 200mg/kg of aspirin showed remarkable inhibition of 90.3%. In the inhibitory effect of the leakage of dye into peritoneal cavity were shown to be 51.9, 56.6 and 58.1% at the combined administration of the extract at the doses of 100, 200 and 400mg/kg with 100mg/kg of aspirin, respectively.

In this study, the accelerated corrosion test by combined deteriorating action of salt damage and freeze-thaw was investigated. freeze-thaw cycle is one method for corrosion testing; corrosion initiation time was measured in four types of concrete samples, i.e., two samples mixed with fly ash (FA) and blast furnace slag (BS), and the other two samples having two water/cement ratio (W/C = 0.6, 0.35) without admixture (OPC60 and OPC35). The corrosion of rebar embedded in concrete occurred most quickly at the $30^{th}$ freeze-thaw cycle. Moreover, a corrosion monitoring method with a half-cell potential measurement and relative dynamic elastic modulus derived from resonant frequency measures was conducted simultaneously. The results indicated that the corrosion of rebar occurred when the relative dynamic elastic modulus was less than 60%. Therefore, dynamic elastic modulus can be used to detect corrosion of steel bar. The results of the accelerated corrosion test exhibited significant difference according to corrosion periods combined with each test condition. Consequently, the OPC60 showed the lowest corrosion resistance among the samples.

This paper presents a model for evaluating the contribution by arch action to shear resistance in shear-critical RC beams. Based on the relationship between shear and bending moment in beams subjected to combined shear and bending, The behavior of a beam is explicitly divided into two base components of the flexural action and the tied arch action. The compatibility condition of the shear deformation that deviates from Bernoulli bending plane is formulated utilizing the smeared truss idealization with an inclined compression chord. From this shear compatibility condition in a beam, the shear contribution by the arch action is numerically decoupled.
