As modern society set in, lifestyle has been changing largely; leisure activity has been expanded and family activity became important. Changes in the lifestyle caused big changes even in fashion industry. Instead of suits, coordination using clothes easy to wear was extended and the need of family look was also raised. Despite the need and marketability of family look, however, family look style clothes depend on the manufacture by orders on the Internet and few brands have been developed unlike the activation of family restaurants or family fast-food restaurants. Thus, this study examined design of family look style T-shirts applying Korean image as one of measures to activate fashion brands of family look. This study purposed to find out self-conceit and identification of our culture by recreating family look as cultural tourism products applying Korean traditional patchwork wrapping-clothes and natural dying techniques and to globalize the products as high value-added ones containing differentiated Korea-style originality. In particular, as Interest in natural dying has been raised because of serious environmental problems and extension of wellbeing culture, products applying natural dying have been developed actively. At this point of time, the development of family look style T-shirts applying natural dying will contribute largely to planning globalization of our brands by developing products with more polished and globalized design.

Power conversion systems used in large gas turbine power plant can be divided into two main part. Because of the initial start-up characteristic of the gas turbine combustor, the gas turbine must be accelerated by starting device(LCI : Load Commutated Inverter) up to 10%~20% of rated speed to ignite it. In addition, the ECS(Excitation Control system) is used to control the rotor field current and reactive power in grid-connected synchronous generator. These two large power conversion systems are located in the same space(container) because of coordination control. Recently, many manufactures develop high speed controller based on function block available in the LCI and ECS with the newest power semiconductor. We also developed high speed controller based on function block to be using these two system and it meets the international standard IEC61131 as using real-time OS(VxWorks) and ISaGRAF. In order to install easily these systems at power plant, main controller, special module and IO module are used with high speed communication line other than electric wire line. Before initial product is installed on the site, prototype is produced and tests are conducted for it. The performance results of Integrated controller and application program(SFC, ECS) were described in this paper. The test results will be considered as the important resources for the application in future.

General phannacological properties of IH-901, a new pharmacological composition as an intestinal metabolite formed from ginseng protopanaxadiol saponins, were investigated in experimental animals administered orally and in vitro test system. IH-901 had no effects on general behavior, pentobarbital sleeping time, spontaneous motor activity, motor coordination of mice, normal body temperature, chemoshock produced by pentylenetetrazole and writhing syndromes induced by 0.8％ acetic acid at the dose of 25 and 250 mg/kg. Gastric secretion of rats and intestinal motility in mice were not also influenced by the administration of IH-901 at doses of 25 and 250 mg/kg. IH-901 (25 and 250 mg/kg) did not change the mean arterial blood pressure and heart rate in conscious rats. IH-901 had no effect on the respiratory rate at the same doses when it was given to anesthetized rats. In in vitro experiments, IH-90l at the concentration of 25$\mu\textrm{g}$/L did not show any direct effect and inhibitory or augmentative action on the histamine-or acetylcholine-induced contractions in the isolated ileum of guinea-pig. Based on these results, it was concluded that IH-901 did not induce any adverse effects in experimental animals.

General pharmacological properties of ADP, a new pharmaceutical composition, which contains a mixed water extract obtained from the mixture of Phellodendron cortex (Phellodendron amurense) and Anemarrhena rhizoma (Anemarrhena asphodeloides), as the active ingredients, were investigated in experimental animals administering orally and in vitro test system. ADP had no influences on general behavior, pentobarbital sleeping time, spontaneous motor activity, motor coordination of mice, normal body temperature, chemoshock produced by pentylenetetrazole and writhing syndromes induced by 0.8% acetic acid at the dose of 150 and 1500 mg/kg. Gastric secretion of rats and intestinal motility of mice were not also influenced by the administration of ADP at doses of 150 and 1500 mg/kg, with the exception of the significant decrease of free HCI concentration at a dose of 1500 mg/kg in rats. ADP (150 and 1500 mg/kg) did not alter mean arterial blood pressure and heart rate in conscious rats. ADP given to anesthetized rats showed no effect on respiratory rate at the same doses. In in vitro experiments, ADP at the concentration of 150 mg/L did not show direct effect and inhibitory or augmentative action on histamine- or acetylcholine-induced contractions in the isolated ileum of guinea-pig. Taken together, these results indicate that ADP does not induce any adverse effects in experimental animals.

This study was conducted to evaluate the nutrition quality of the commercial infant formulas and to seek the solution to the establishment of the standard of nutrient requirements for infant formula in Korea. Nutrition informations were obtained from the labels of nineteen commercial infant formulas manufactured by 3 different companies, and the actual amounts of some nutrients were analyzed and compared to the labeled amounts. In addition, the nutrient composition of the commercial infant formulas was compared to the composition of breast milk, RDA for infants, and Codex standard for infant formula. The kind of minerals, vitamins and special components added to the commercial infant formulas were the major differences among 3 manufacturers. For some nutrients, the analyzed amounts were lower than the labeled amounts. In addition when different batches of the same kind of infant formula were analyzed, the large variations in the amounts of certain nutrients were noted. These data suggest that the nutrition labeling informations need to be validated, and nutrients added to the formulas are to be homogenized thoroughly. In order to solve these problems, therefore, like other countries, we need to establish the standard of nutrient requirements for infant formulas. Considering the available data on breast milk composition, RDA for infants and coordination with the international standard, we suggest the adoption of the Codex standard for infant formula may be the best way to manage the nutrition quality of commercial infant formulas at the present time.

In order to understand the variation of air quality and the concentration of atmospheric particulates in Chengdu Second Ring Road renovation project, this paper starts to investigate the surrounding residents' opinions on the influenced environment and their daily lives via questionnaires. Then the study numerically simulates the change rule of atmospheric particulates in terms of time and space by using the Gaussian dispersion-deposition model and the compartment model. The optimized scientific scheme is selected by the improved fuzzy analytical hierarchy process(FAHP) to help decision making for the future urban reconstructions. Finally, the reduced emissions of atmospheric particulates are measured when the improvement scheme is provided. According to the study, it can be concluded that the concentration of atmospheric particulates increases rapidly in central Chengdu city during the renovation project, which results in worsening air quality in Chengdu during March 2012 to March 2013. Taking related measures on energy saving and emission reduction can effectively reduce the concentration of atmospheric particulates and promote economic, environmental and social coordination.

We are developing a biomimetic robot based on the Sea Lamprey. The robot consists of a cylindrical electronics bay propelled by an undulatory body axis. Shape memory alloy (SMA) actuators generate propagating flexion waves in five undulatory segments of a polyurethane strip. The behavior of the robot is controlled by an electronic nervous system (ENS) composed of networks of discrete-time map-based neurons and synapses that execute on a digital signal processing chip. Motor neuron action potentials gate power transistors that apply current to the SMA actuators. The ENS consists of a set of segmental central pattern generators (CPGs), modulated by layered command and coordinating neuron networks, that integrate input from exteroceptive sensors including a compass, accelerometers, inclinometers and a short baseline sonar array (SBA). The CPGs instantiate the 3-element hemi-segmental network model established from physiological studies. Anterior and posterior propagating pathways between CPGs mediate intersegmental coordination to generate flexion waves for forward and backward swimming. The command network mediates layered exteroceptive reflexes for homing, primary orientation, and impediment compensation. The SBA allows homing on a sonar beacon by indicating deviations in azimuth and inclination. Inclinometers actuate a bending segment between the hull and undulator to allow climb and dive. Accelerometers can distinguish collisions from impediment to allow compensatory reflexes. Modulatory commands mediate speed control and turning. A SBA communications interface is being developed to allow supervised reactive autonomy.

This paper proposes a core technology for a micro river monitoring terminal device suitable for flood monitoring in small rivers and valleys. Our proposed device is basically equipped with a 77GHz radar, gyro and accelerometer sensors. To measure the flow velocity and water level, we proposed a signal processing technique that extracts pure water energy components from the observed Doppler velocity and reflection intensity from the radar. And to determine the stability of the river structure equipped with our device, we constantly monitor the displacement of the measured values of the gyro and accelerometer sensors. Experimental result verified that our method detects pure water energy in various river environments and distinguishes between flow velocity and water level well. And we verified that vibration and position change of structures can be determined through a gyro sensor. In future research, we will work to build a secure digital twin river network by lowering the cost of supplying RF-WAV devices. Also we expect our device to contribute to securing a preventive golden time in rivers.

Using murine immortalized microglial cells (BV-2), we examined the regulation of RANTES production stimulated by lipopolysaccharide (LPS), focusing on the role of mitogen-activated protein kinase (MAPK) and nuclear factor $(NF)-{\kappa}B.$ The result showed that RANTES (regulated upon activation of normal T cell expressed and secreted) was induced at the mRNA and protein levels in a dose- and time-dependent manner in response to LPS. From investigations of second messenger pathways involved in regulating the secretion of RANTES, we found that LPS induced phosphorylation of extracellular signal-regulated kinase (Erk), p38 MAPK and c-Jun-N-terminal kinase (JNK), and activated $(NF)-{\kappa}B.$ To determine whether this MAPK phosphorylation is involved in LPS-stimulated RANTES production, we used specific inhibitors for p38 MAPK and Erk, SB 203580 and PD 98059, respectively. LPS-induced RANTES production was reduced approximately 80% at $25\;{\mu}M$ of SB 203580 treatment. But PD 98059 did not affect RANTES production. Pyrrolidine-dithiocarbamate (PDTC), $(NF)-{\kappa}B$ inhibitor, reduced RANTES secretion. These results suggest that LPS-induced RANTES production in microglial cells (BV-2) is mainly mediated by the coordination of p38 MAPK and $(NF)-{\kappa}B$ cascade.
