  • This study is done in Shanghai area by sample survey of female college students in their lower 20s. Through direct contact survey, this study collected and analyzed information on figure to understand feature of breasts and measurements of body to provide base information to improve product of brassiere for adult female in China. Data was analyzed by using SPSSWIN 13.0 Program and SAS 9.0. 1. From a result of factor analysis on 40 items of measures to derive the components of the shape of the breast, 6 factors were derived such as the factors to show the obesity of the bust, to show the ratio of the upper and lower area of the lower bust, droop and volume, to show the internal shape and broadness of the bust, to show the location and vertical size of the bust, to show the protrusion of the bust and the eternal shape of the bust. 2. From a result of classification on the shape of the breast of the Chinese women in their early 20s, 4 types were selected. Type 1 is the protrusion type that a woman has a broad drooped breast due to the development in the upper and lower parts of the chest as well as the highest height, a high degree of obesity in the bust part, big volume and much protrusion. Type 2 is the hemisphere type that the degree of obesity in the breast is second to Type 1 and a breast is located at a region higher than Type 1 as the degree of obesity in the breast is secondly highest, the lower part of the bust is bigger than the Type 1 and the degree of being broad and drooped is second to Type 1. Type 3 is the cone type with a breast of being drooped and broad a little bit and a certain degree of a volume. Type 4 is the flat type with the smallest value in the item that shows the obesity of the bust area and with the smallest value in the R$\ddot{o}$hrer index to have the small and slender body type for the bust area, which is somewhat flat due to a low slope at the internal side of the bust.

  • Pink rot of Palm was occurred at Yeuju area in 2001 and 2003. Infected plants showed rotting at the leaf-stock bases and killing of the terminal bud. The first symptoms are dark brown necrotic areas on the stem. Bases of infected frond may be covered with pink spores and the spots produced oozing gum pockets. Oozing lesions occur on the stems, and leaves turn brown and droop. The causal agent were isolated from salmon-pink spores sporulating on the leaf sheaths and necrotic stem tissues. Pathogen were isolated from freshly infected tissues were identified as Gliocladium vermoseni based on mycological characteristics. Fungus were grown plenty on PDA culture. Temperature for mycelial grown was tested at 5 to $40^{\circ}C$ and optimal temperature was $25^{\circ}C$ and was not nearly grew at temperature above $35^{\circ}C$. Artificial pathogenicity were tested on 9 species of Palm family in the wound inoculation and symptoms showed similar to those observed in the field. This is the first report on pink rot of palm in Korea.

  • Research into underwater wireless networks that enable the monitoring and controlling of the ocean environments has been continuing for disaster prevention and military proposes, as well as for the exploitation of ocean resources throughout the world. A research group led by Hoseo university has been studying a distributed underwater monitoring and controlling network. In this study, we developed an interpolator for acoustic communication between an underwater base station controller and underwater base station, which is included in this network. The underwater acoustic communication provided by this network defines four links whose sampling rates are different. Low power consumption is one of the most important requirements. Therefore, we adopted CIC interpolators, which are known to act as filters with a low power consumption, and some CIC interpolators with an appropriate changing rate were selected depending on the link. However, these interpolators have a large passband drop and wide transition region. To solve these problems, we added a compensator and half-band filter. After verifying the algorithm by using Matlab, we designed and verified it with Verilog-HDL in a ModelSim environment.

  • UV irradiation produces free radicals and related reactive oxygen species (ROS), and these are injury to all most of organisms of skin cells and extracellular matrix (ECM). In addition, free radicals and ROS stimulate the overexpression of matrix metalloproteinases (MMPs) that can degrade most components of ECM such as collagen. Since collagen constitutes almost of skin connective tissue, their disarrangement causes wrinkle formation and droop of skin. Therefore, scavenging activity on free radicals, ROS and suppression of MMP-1 is expected to prevent skin photoaging. In this study, to investigate the relationship between photoaging and Draconis sanguis, we examined the effects of antioxidant, in vitro MMP inhibition and expression of UVA-induced MMP-1 in human dermal fibroblasts. Draconis sanguis was found to show scavenging activities of radicals and ROS with the $IC_{50}$ values of $183{\;}{\mu}g/mL$ against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical and $30{\;}{\mu}g/mL$ against superoxide radicals in the xanthine/xanthine oxidase system, respectively. Draconis sunguis inhibited the activities of MMP-1 in a does-dependent manner and the $IC_{50}$ value calculated from semi-log plots was $200{\;}{\mu}g/mL$. Also, UVA induced MMP expression was reduced $74\%$ by treatment with Draconis sanguis, and MMP-1 mRNA expression was reduced in a dose-dependent manner. Therefore Draconis sanguis was able to significantly inhibit MMP expression in protein and mRNA level. All these results suggested that Draconis sanguis may act as an anti-photoaging agent by antioxidation and reducing UVA-induced MMP-1 production.
