The Relationship of Socioeconomic and Behavioral Risk Factors With Trends of Overweight in Korea
Shin, Jin Hee,Dupre, Matthew E.,Ostbye, Truls,Murphy, Gwen,Silberberg, Mina The Korean Society for Preventive Medicine 2015 Journal of Preventive Medicine and Public Health Vol.48 No.6
Objectives: Previous studies have shown that overweight (including obesity) has increased significantly in Korea in recent decades. However, it remains unclear whether this change has been uniform among all Koreans and to what extent socioeconomic and behavioral factors have contributed to this increase. Methods: Changes in overweight were estimated using data from the 1998, 2001, 2005, 2007-2009, and 2010-2012 Korea National Health and Nutrition Examination Survey (n=55 761). Results: Overweight increased significantly among men but not among women between 1998 and 2012. Changes in socioeconomic and behavioral factors over the time period were not associated with overall trends for both men and women. However, we found significant differences in the prevalence of overweight relative to key risk factors. For men, overweight increased at a significantly greater rate among the non-exercising (predicted probability [PP] from 0.23 to 0.32] and high-calorie (PP from 0.18 to 0.37) groups compared to their active and lower-calorie counterparts, respectively. For women, overweight increased only among the non-exercising (PP from 0.27 to 0.28) and low-income (PP from 0.31 to 0.36) groups during this period. Conclusions: These findings suggest that programs aimed at reducing overweight should target Korean men and women in specific socioeconomic and behavioral risk groups differentially.

Traction Control Using HTD10-40 Torque Divider

Controlling traction in hydraulic propel applications can be a slippery situation. Good traction demands all driving wheels take an equal share of propulsion loads, without slipping, scuffing, or cavitating. There are a wide variety of hydraulic propel circuits and products available to today’s vehicle designer including both closed and open circuit pumps and motors. Economical series circuits are prone to cavitation as inside and outside turning radii differ. Parallel circuits consume energy in the flow dividers and still require additional accommodation for differing wheel speeds. This paper details the approach leading to the development of a multifunctional cartridge valve that divides torque between loads in a series circuit. It discusses the strengths and weaknesses of traditional traction control circuit configurations and the benefits of the new approach. HydraForce HTD valves control traction, accommodate differential flows for cornering, save component cost, and save energy when compared to traditional flow dividing valves.

Purpose: This study aimed to assess the performance of the Ebel standard-setting method for the spring 2019 Royal College of Physicians and Surgeons of Canada internal medicine certification examination consisting of multiple-choice questions. Specifically, the following parameters were evaluated: inter-rater agreement, the correlations between Ebel scores and item facility indices, the impact ofraters’ knowledge of correct answers on the Ebel score, and the effects of raters’ specialty on inter-rater agreement and Ebel scores. Methods: Data were drawn from a Royal College of Physicians and Surgeons of Canada certification exam. The Ebel method was applied to 203 multiple-choice questions by 49 raters. Facility indices came from 194 candidates. We computed the Fleiss kappa and thePearson correlations between Ebel scores and item facility indices. We investigated differences in the Ebel score according to whethercorrect answers were provided or not and differences between internists and other specialists using the t-test. Results: The Fleiss kappa was below 0.15 for both facility and relevance. The correlation between Ebel scores and facility indices waslow when correct answers were provided and negligible when they were not. The Ebel score was the same whether the correct answerswere provided or not. Inter-rater agreement and Ebel scores were not significantly different between internists and other specialists. Conclusion: Inter-rater agreement and correlations between item Ebel scores and facility indices were consistently low; furthermore,raters’ knowledge of the correct answers and raters’ specialty had no effect on Ebel scores in the present setting
Experimental and numerical study of the load distribution in a ball-screw system
Romuald Bertolaso,Mohammed Cheikh,Yoann Barranger,Jean-Christophe Dupré,Arnaud Germaneau,Pascal Doumalin 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.4
In this work, load distribution on ball-screw systems (BSS) is determined by experimental techniques. Two optical techniques areused: photoelasticity for stress-field measurement and the mark-tracking method for displacement-field determination. In parallel to theexperimental study, finite element method (FEM) and analytical solutions are used to calculate the loads applied on each ball of the BSS. Experimental results are used to validate the choice of boundary conditions and contact conditions between ball-screw and ball-nut in theFEM solution. The validation criterion is the correspondence between numerical and experimental fringes representing the differences ofprincipal stresses. In addition to the study of load distribution, this paper presents the influence of the angle of contact direction on thestress distribution in BSS.
Charge and spin dynamics in the electron-doped high temperature superconducting cuprates
G. V. M. Williams,S. Kramer,R. Dupree 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
We show that the63Cu and17O NMR spin-lattice relaxation rates from the electron-doped high temperature superconducting cuprates (HTSC), Sr0:9La0:1CuO2 and Pr1:85Ce0:15CuO4 are consistent with antiferromagnetic spin uctuations in the CuO2 planes.However, unlike the hole-doped HTSC, there is no normal-state pseudogap or spin-gap. Furthermore, there is no evidence for aslowing down of the spin dynamics that is observed in underdoped and hole-doped HTSC and attributed to electronic phaseseparation. We also nd that the normal-state static spin susceptibility in Sr0:9La0:1CuO2 is only . 15% of that observed in the hole-doped HTSC.

Xylan is the major hemicellulose. The main chain is consisted of xylose residues, whereas the side chain differs by the plant species. For instance, xylan from hardwood is substituted by glucuronic acid and acetylated. In nature, fungi degrade xylan, producing various enzymes. In general, xylan main chain is degraded into xylooligosaccharides by xylanase. Thus, its substrate recognition is a crucial for the efficient digestion of xylan. Ample studies have reported about xyalanases’ substrate specificities towards xylan and xylooligosaccharides substituted with glucuronic acid. On the other hand, little is known about the effect of acetylation due to difficulty in extracting acetylated xylan. The basidiomycetes Phanerochaete chrysosporioum is a model organism for white rot fungi. P.c degrades hardwood in nature and has various enzymes. P.c has three xylanases belonging to GH family 10 and 11. In general, wood decay fungi have GH family 10 xylanases and mold has GH family 11 xylanases. Therefore, this study prepared substrates, investigated the reaction property of two xylanases from the P.c and compared GH family 10 and 11 xylanases’ characteristics. Finally, we proposed xylan degradation system using each xylanase.
