The purpose of this study, which has been conducted as a government and academic joint project, is to introduce the design, production and installation of the structures exhibited to let people know the meaning the environment-friendly eco-park - Haneul Park that is located in Mapo-gu, Seoul. The exhibition was held as a part of Green Garden Panorama of Seoul Design Fair 2010 and used the stands of Jamsil Sports Complex as the exhibition space. The key contents of the exhibition consist of four elements; firstly, green plants were placed on the first and second floor stands of the complex in order to create the space inside the main stadium as a space that symbolized green environment. Secondly, the usability of the containers of food was maximized to attract the spectator's interest and induce desire to have it. Thirdly, the efforts of the Mapo-gu office for green environment were emphasized using environment-friendly materials. The process and meaning of the transformation of Nanji Island that had been a waste dump site in the past into Haneul Park - an environment-friendly eco-park were expressed by a four-stage space structure. The majority of installations placed in each stage were sold to visitors during the event so as to minimize the generation of wastes after the event.

In recent years after the Sewol Sank, the surroundings of Fire have rapidly changed and citizens need for Fire have been demanding very high. Under these situations, in order for satisfaction to all these demands, Seoul Metropolitan Fire & Disaster Headquarters(SMFDH) have made improvements of Golden Time in the field of disaster as the leader of Fire Department in Korea. SMFDH has been practicing many kinds of plans, or projects to achieve Gold Time of 55 types of disaster. However, There have been questioning about all these projects if they are working for the achievement. The purpose of this study is to scrutinize current projects for Golden Time Targeting focused on Mapo fire fighters as first responders and to cope with how to make them better for Seoul Citizens' safety by using SPSS(Statistical Package for the Social Science) Statistics 24. The result of this study presents that how we can find to be all the project for Golden Time Targeting running well. And This study will be positively applied to Seoul fire policies or helped for setting them up better.

This study was performed in order to analysis the landscape change and cause of scenic sites and surrounding environment is located in the Urban Residential Area since modern. The study was carried out using of field observations, literature review, cadaster map analysis from 1962 to 2010, and survey. It trace about Seongnagwon, Mapo Choi Sa-Young's old house, Seoul Seonjamdanji, Seoul Hanyang castle and those can be process of change per period. Also, it examine to original view of cultural assets and analysis about lots alteration with landscape alteration. Seongnagwon has original view which constructed the Songseokjeong and pond in 1954. Mapo Choi Sa-Young's old house has original view that move to Sungbook-dong and restore an old house. Seoul Seonjamdanji has it define original view that remained ruins by 1960's development. Seoul Hanyang castle has original view that stone fortress. Seongnagwon's landscape was changed by institutional factors. Mapo Choi Sa-Young house's landscape was changed by society economic factors. Seoul Seonjamdanji was changed by society economic and institutional factors. Seoul Hanyang castle was changed by technical and institutional factors. Generally cultural heritage of Sungbook-dong was changed by institutional and society economic factors. It is guessed that Seoul urban planning influenced Sungbook-dong development. The establishment of capitalistic economy system was backgrounds to it. Therefore, it expect to realized desirable landscape alteration that recognized potential value as culture resources.

Melanin plays a key role in the protection of skin from ultraviolet light that generates reactive oxygen species (ROS), such as superoxide, hydroxyl radical, singlet oxygen and hydrogen peroxide. However, the ROS leading to the oxidation of lipids, proteins and DNA are involved in the overproduction of melanin that is known to cause melasma, age spots and freckles. Among the herb medicines, Ulmus macrocarpa used in this study was reported to contain flavonoids as a main component. The aim of this study is to investigate the whitening and anti-oxidant effects of Ulmus macrocarpa ethanolic extracts (UMEE) in B16F1 cells. UMEE below $3.12{\mu}g/ml$ did not show cytotoxicity. In an anti-oxidant experiment, UMEE showed not only high reducing power and scavenging activity on DPPH, but it was also observed that UMEE exhibit an inhibitory effect on lipid peroxidation. UMEE did not display an inhibitory effect on tyrosinase activity in vitro. However, UMEE inhibited melanin synthesis in B16F1 cells. In addition, UMEE reduced the expression levels of tyrosinase and tyrosinase-related protein-2 (TRP-2), which are key enzymes in melanogenesis. These results indicate that UMEE exert a whitening effect through the inhibition of both tyrosinase and TRP-2 expressions as well as anti-oxidant activity, suggesting that UMEE could have the functional potential for a whitening effect on the skin.

Heungseon Daewonwang Lee Ha-eung was the father of King Gojong, who appointed as Daewongun in December 1863. On February 2, 1898, after the death of Heungseon Daewongun, he was buried in the Asodang in Gongdeok-dong, Mapo-gu, where he normally enjoyed. On August 24, 1907, he was promoted to Daewonwang. After being promoted to Daewonwang, the Asodang tomb was relocated to Daedeok-dong, Paju, and the tomb was promoted to Won. In the Wonchim space promoted to the facilities suitable for the original were created, and through this, it was possible to analyze the characteristics of the Wonchim and the Wonchim space of the tomb on the Heungwon. In addition, by comparing and analyzing the spatial composition between Myo and Won, it was possible to derive the spatial composition characteristics of the Joseon Dynasty Won(園), and Myo(墓). Looking at the research results derived through the analysis of 『Heungwon Cheonbong Registration』, tomb of Heungseon Daewongun, located in Asodang, Mapo-gu, was promoted to Heungseon Daewonwang, and was relocated as Jangneung in Uncheon-ri, Paju, the former tomb of King Injo. The promoted of tomb was also promoted from Myo to Won. In addition, the storehouses and facilities used in Mapo Asodang were moved to Uncheon-ri, Paju, and reused. Newly constructed monuments, Biseog, Chimgak, Jemulgo, Subokcheong, Hongsalmun, and Wells according to the promoted of the Won. It was confirmed that there is a difference in the spatial composition of Won and Myo when looking at the difference in the composition of the ornament objects and the facility.

Molecular orientation and polarity of solubilization site of dipolar azobenzenes solubilized in micellar solutions are discussed. The polarity of solubilization was estimated by using Taft $\pi$$^*$ scale with linear solvation energy relationship, $\Delta$E=$\Delta$E$_0$ + S($\pi$$^*$ + d$\delta$)+a$\alpha$ + b$\beta$. Hydrogen bonding effects were taken into account for the estimation of micropolarity. The polarity that azobenzenes experienced in the miceliar solutions was close to water which represented that the azobenzenes were mostly solubilized at the interface. For the orientations of azobenzenes were concerned, the nitro group of NPNOH faced the interface and the hydroxy group of NPNO$^-$ located at the interfacial area.

To increase the robustness of tile feedforward tracking control system, a new discrete time sliding function has been defined and utilized for the formulation of control law, In adaptive case the robustness is achieved by using both a normalized gradient algorithm with deadzone and a sliding function-based nonlinear feedback, while in nonadaptive case by using only a sliding function-based nonlinear feedback.

In order to analyze the thermal effects of the rotor models, the finite element technique was used in this study. The length of the hat was investigated as a design parameter. At the start of each brake application the disk surface temperature rapidly increases to a maximum value and then decays due to external cooling and thermal conduction to the hat. The calculated results indicate that the long length of the hat shows the minimum deformation in axial direction, which is related to the thermal problems, coned wear, vibration and noise.
