Adaptive Image Segmentation Based on Histogram Transition Zone Analysis
Acuna, Rafael Guillermo Gonzalez,Mery, Domingo,Klette, Reinhard Korean Institute of Intelligent Systems 2016 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.16 No.4
While segmenting "complex" images (with multiple objects, many details, etc.) we experienced a need to explore new ways for time-efficient and meaningful image segmentation. In this paper we propose a new technique for image segmentation which has only one variable for controlling the expected number of segments. The algorithm focuses on the treatment of pixels in transition zones between various label distributions. Results of the proposed algorithm (e.g. on the Berkeley image segmentation dataset) are comparable to those of GMM or HMM-EM segmentation, but are achieved with significantly reduced computation time.
Public Administration Reform and Anti-Corruption: Pushing the Limits or Understanding its Dynamics?
Jairo Acuna-Affaro 연세대학교(미래캠퍼스) 빈곤문제국제개발연구원 2008 地域發展硏究 Vol.17 No.2
Is anti-corruption important to public administration reform? Or is public administration reform important for the fight against corruption? How are anti-corruption and public administration reform inter-linked? How can public administration reform areas be prioritized in order to push up anti-corruption agenda? How to prioritize and sequence reform/strategies in these two broad and complex policy areas? This paper aims to provide initial approximations on how to answer these questions. Considering corruption as a symptom of outcomes of unresolved governance and public administration, this paper argues that public administration reform and anti-corruption cannot be treated as separate processes on their own. The paper discusses the importance of data collection and highlights how some APEC economies have managed to improve both public administration and anti-corruption by way of collecting data. In addition, the fight against corruption does not happen in a vacuum and needs to be tailored down to country specifics. Therefore while public administration reform and anti-corruption are mutually reinforcing each other, attention should be paid to levels and degrees.
Effect of Ursolic Acid on Metabolic Syndrome, Insulin Sensitivity, and Inflammation
Alejandra M. Ramırez-Rodrıguez,Manuel Gonzalez-Ortiz,Esperanza Martınez-Abundis,Natalhie Acuna Ortega 한국식품영양과학회 2017 Journal of medicinal food Vol.20 No.9
To evaluate the effect of ursolic acid on metabolic syndrome, insulin sensitivity, and inflammation, a randomized, double-blind, placebo-controlled clinical trial was carried out in 24 patients (30–60 years) with a diagnosis of metabolic syndrome without treatment. They were randomly assigned to two groups of 12 patients, each to receive orally 150 mg of ursolic acid or homologated placebo once a day for 12 weeks. Before and after the intervention, the components of metabolic syndrome, insulin sensitivity (Matsuda index), and inflammation profile (interleukin-6 and C-reactive protein) were evaluated. After ursolic acid administration, the remission of metabolic syndrome occurred in 50% of patients (P = .005) with significant differences in body weight (75.7 ± 11.5 vs. 71 ± 11 kg, P = .002), body mass index (BMI) (29.9 + 3.6 vs. 24.9 ± 1.2 kg/m2, P = .049), waist circumference (93 ± 8.9 vs. 83 + 8.6 cm, P = .008), fasting glucose (6.0 ± 0.5 vs. 4.7 ± 0.4 mmol/L, P = .002), and insulin sensitivity (3.1 ± 1.1 vs. 4.2 ± 1.2, P = .003). Ursolic acid administration leads to transient remission of metabolic syndrome, reducing body weight, BMI, waist circumference and fasting glucose, as well as increasing insulin sensitivity.
