Los nuevos frutos de oro. Aparato productivo de piña y naranja en la Zona Norte, Costa Rica (1974-2015)

Se analiza la evolución piñera y naranjera en la Zona Norte Norte, mediante la construcción del aparato productivo mediante la prosopografía y la metodología relacional de los derechos humanos. El modelo de desarrollo implementado desde los ochenta ha facilitado la instalación de compañías agroindustriales para la exportación, con unos US$101 millones de naranja y unos US$800 millones de piña para 2015, principalmente en el norte, y acumuladas en pocas élites-personas con gran influencia política y económica. Esto incide para que esta sea una de las zonas agroindustrialmente más productivas y, al mismo tiempo, una de las de mayor desigualdad y pobreza. Se vuelve necesario enfrentar las adversas situaciones con acompañamientos alternativos ligados a la autonomía alimentaria y laboral.

마티스의 이국취미와 작품에 나타난 색채

The purpose of this study is to extract the color chip from the works of Matisse with the exotic tastes, to analyze the characters of adjacent colors, and to suggest the color coordination of artistic character. The research method is based on the literature study which analyzes visual materials. The results are as follows. Considering the colors of Japanese taste, He employs vivid and strong tone in red, yellow, and blue, light tone in pink, purple, and green and deep tone in green, purple, blue and black. His color scheme is very bold and splendid. In his Algerian taste, red is very popular, but an attention should be paid in his development of orange and blue tones. In general, the usage of various tones brings colors into less relief and make the contrast of tones more conspicuous. His Spanish taste, based on red and orange, attracts attentions with strong impressions, but sometimes, dark or adjacent pale tones creates strong, mild and murky atmosphere. The Moroccan taste, based on the development of blue tones which have strong attraction implies the lightness but represents silent and calm. The Rumanian taste, represented in primary colors of red, yellow and blue and achromatic colors is bright and clear. In addition, its light tone in various colors represents peace and romance. The coordination of the exotic colors with the unique adjacent colors created by Matisse is not based on the established color coordination theory, but extracts colors in the aspect of culture borrowing. Therefore, it can double the effects of the color scheme expressed in the existing designs and be used as the global and multi-cultural design sources.

Spectrophotometric Determination of Some Catecholamine Drugs Using Metaperiodate

A rapid spectrophotometric procedure for the determination of isoprenaline salts, levodopa, dopamine hydrochloride, and dobutamine hydrochloride, either in the drug substances or in pharmaceutical formulations, is described. The method is based on the development of orange, red, or violet products with sodium metaperiodate in an aqueous alcoholic medium. The reaction is suggested to proceed via oxidative cyclization of the catecholamine to form an aminochrome. The wavelengths of maximum absorption range from 465 to 520 nm. The structure of the cyclization product was confirmed by ultraviolet, infrared, and nuclear magnetic resonance spectroscopy and microanalysis data.
