We study galaxy evolution with the large-scale environment with confirmed galaxy clusters from multi-object spectroscopy (MOS) observation. The observation was performed with Inamori Magellan Areal Camera and Spectrograph (IMACS) mounted on the 6.5 m Magellan/Baade telescope in Las Campanas Observatory. With the MOS observation, we spectroscopically confirm 34 galaxy clusters, including three galaxy clusters discovered in Kim et al. (2016) and 11 of them have halo mass of > 10^14.5 M_◉. Among the confirmed clusters, 12 galaxy clusters are part of large-scale structure at z ~ 0.9, and their size stretches to 40 Mpc co-moving scale. In this study, we checked the 'web feeding model,' which postulates that more linked (with their environment) galaxy clusters have less quenched populations by investigating the correlation between properties of confirmed galaxy clusters and the large-scale structure environment. Lastly, we found that galaxy clusters that make up the large-scale structure have larger and widely spread values of total star formation density (ΣSFR/M_halo) than typical clusters at similar redshifts.

En realidad ningún otro cineasta español que Pedro Almodóvar ha centrado tan obsesivamente en Madrid. Casi todas sus obras se ocupan de la capital de España como espacio cinematográfico. Como uno de los protagonistas de La Movida, Almodóvar es un producto de Madrid de la Transición que dió luz a la nueva sociedad democrática. En principio, Madrid en las películas de Almodóvar se convierte en un espacio carnavalesco desde la perspectiva bajtiniana. El crítico ruso ha exaltado la plaza pública de los pueblos medievales europeos como el espacio carnavalesco en el que los contactos libres y familiares se realizan y el principio de lo corporal y lo material predomina. Para Bajtín, el carnaval es básicamente un rito político en el que el individuo parece dotado de una segunda vida que le permite establecer nuevas relaciones verdaderamente humanas con sus semejantes sin ninguna represión. Así que en el mundo carnavalesco todo lo sagrado, lo oficial y lo privilegiado se destronan, y en cambio lo grosero, lo extra-oficial y lo bajo se reivindican. Como los participantes del carnaval, los personajes de Almodóvar disfrutan de una segunda vida en un Madrid del mundo al revés. Por otra parte, la representación carnavalesca de Madrid tiene una tradición rica y larga en el arte español. Entre muchos artistas Goya, Arniches, Valle-Inclán y Buñuel son los antecedentes destacados de esta tradición. Así pues se puede concluir que la estética del cine de Almodóvar está anclada en la tradición hispánica del carnavalismo más bien que la estética global de la posmodernidad.

The $M_{BH}-{\sigma}$ relation for galaxies is a stand-out illustration of the co-evolution of galaxies and their central supermassive black holes (SMBHs); however, how this co-evolution occurs and whether this relation holds for SMBHs of the early universe is still a matter of debate. In order to study this at higher redshifts, quasi-stellar objects (QSOs) are the best targets, due to their large sample size and effective $M_{BH}$ estimation. Nevertheless, it is difficult to examine properties of their host galaxies, simply due to the sheer brightness of the QSO itself. Here, we discuss a distinctive method in studying these QSO host galaxies, via gravitational lensing (GL). GL offers a unique approach in determining the mass of the lens object, in this case the host galaxy. QSOs from the SDSS quasar catalog were searched in the Hubble Space Telescope archives, and GL features around them were visually inspected. One such candidate is SDSS J1114-00; to increase its robustness as a GL system candidate, it was observed with the Inamori-Magellan Areal Camera & Spectrograph (IMACS) on the Magellan Baade Telescope at Las Campanas Observatory, to check whether the GL features have identical colors, meaning they are likely to originate from the same source. After confirmation of such GL systems, a sufficiently large sample will enable us to examine the $M_{BH}-{\sigma}$ relation at various redshifts, and in turn, investigate the co-evolution of SMBHs and their host galaxies.

Fixed-bed adsorption of metal ions on chitosan bead was studied to remove heavy metal ions in waste water. Chitin was extracted from carb shell and chitosan was prepared by deacetylation of the chitin. The chitosan in bead was used as an adsorbent for heavy metal ions. Freundlich and Langmuir isotherm was determined from the experimental results of equilibrium adsorption for individual metal ion ($Cu^{2+}$, $Co^{2+}$, $Ni^{2+}$) on chitosan bead. Adsorption strength of metal ions decreased in the order of $Cu^{2+}$>$Co^{2+}$>$Ni^{2+}$ ion. Breakthrough curves of single and multicomponent adsorption for metal ions were obtained from the experimental results of fixed-bed adsorption. The breakthrough curves were analyzed by simulation with fixed-bed adsorption equation based on LDFA (linear driving force approximation) adopted LAS (ideal adsorbed solution) theory which can predict multi-component adsorption isotherm from individual adsorption isotherm. The behavior of fixed bed adsorption for single and multi-component system could be nicely simulated by the equation.

Macroorganisms capable of utilizing sodium dodecylbenzenesulfonate(SDBS, soft type) as a sole carbon source were isolated from nature by using SDBS agar plate technique. Iwolated bacteria were examined primarily for biodegradation ability of SDBS, and followed by testing for resistance to several kinds of metal compounds and antibiotics. Among them(152 strains), one strain showed a excellent SDBS-degrading ability with a resistance to amipicillin and rifampicin was selected. This bacterium was identified as Klebsiella sp. and harbored two plasmids of about 4 and 5 kilobases. SDBS-degrading ability was lost when the plasmids were cured by mitomycin C. It was revealed that the degradation of SDBS was controlled by the plasmid DNA encoding genes. The two plasmids were stably maintained in Escherichia coli C600.

Robert Venturi's theories like 'Complexity and Contradiction in Architecture' and 'Symbolism of Architecture' had a major impact on architects in postmodern culture and we could have his contextual understandings in those theories. In his early books, "Complexity and Contradiction in Architecture" and "Learning from Las Vegas", Robert Venturi showed theories related to context several times. But with looking at existing books or papers, we could barely see well-organized studies about his contextual understandings. So this study shows contextual approaches and thoughts with those theories, 'Complex and contradictory architecture', 'Architectural order and conventional architecture', 'Discontinuity in internal and external architecture', and 'Symbolism of architecture' in his two books. In those four theories, Venturi's contextual understandings are as fellows. To begin with, he developed contextual theories in architecture, understanding a whole building embracing each architectural factor, with architectural thoughts of complexity and contradiction. Second, he stressed architectural order to link each contradictory factor and used conventional architecture, as for existing common and ordinary things, to make available communication. Conventional factors were applied to urban viewpoints. Given the fact that contemporaries shared those factors, we could see contextual understandings in his approach. On top of that, unlike modern architects, he understood that functions of the inside and the outside were two different things. Based on contextual thoughts, he tried applying 'facade' that is one side providing an interface between in and out of a building to surroundings. Last, he wanted to express any meaningful connection between present and past, using symbolism in architecture. Presented by symbolism of architecture, architectural functions, architectural uses, historical meaning, ordinary factors, or something were also based on sharing in contemporary people. As the methodology to show these contextual factors, Venturi used an approach of symbolism.
