The purpose of this study is to investigate the inelastic behavior of hollow reinforced concrete bridge column sections with reinforcement details for material quantity reduction and to provide the details and reference data. Among the numerous parameters, this study concentrates on the shape of the section, the reinforcement details, the diameter of the transverse reinforcement and loading types. Eighteen column section specimens were tested under quasi-static monotonic loading. In this study, the computer program RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology) was used. A modified lateral confining effect model was adopted for the hollow bridge column sections. This study documents the testing of hollow reinforced concrete bridge column sections with reinforcement details for material quantity reduction and presents conclusions based on the experimental and analytical findings.:

The government of each country is making a policy of expanding recycling of wastes and waste-to-energy to mitigate the greenhouse gas emissions to cope with climate change. This paper attempts to analyze the economic effects of waste disposal & materials recycling services (WDMRS) sector using 2012 input-output (IO) table published in 2014. To this end, we deal with three sectors: waste disposal, materials recycling services, and WDMRS sectors. More specifically, the production-inducing effect, value-added creation effect, and employment-inducing effect of the WDMRS sector are investigated based on demand-driven model. The supply shortage effect and the price pervasive effect are also examined employing supply-driven model and Leontief price model, respectively. The results show that the production or investment of 1.0 won in the WDMRS sector induces the production of 1.9324 won and the value-added of 0.7217 won in the national economy. Moreover, the production or investment of 1.0 billion won, supply shortage of 1.0 won, and a price increase of 10.0% in the WDMRS sector touch off the employment of 15.2462 persons, production loss of 2.0589 won, and an increases in overall price level by 0.0699%, respectively. This quantitative information can be usefully utilized inassessment of the WDMRS sector-related investment and policy.

The aim of this study is to investigate the clinical significance of acanthosis nigricans scales and locations in order to validate the relation of hyperinsulinemia and insulin resistance in obese children. We conducted a retrospective analysis of clinical records of obese children who visited Chosun University Hospital between January 2013 and February 2014 due to their obesity. Five anatomical sites were examined for evaluation of acanthosis nigricans. Clinical characteristics were compared according to the presence and severity of acanthosis nigricans. Among 55 children, 37 children had acanthocis nigricans. A consensus score of acanthosis nigricans was calculated by summing the scores of five locations. The diagnostic categories were: No acanthosis nigricans group, mild group, moderate group, and severe group. Elevated acanthosis nigricans total score showed strong association with elevated BMI, triglyceride, and c-peptide in all groups. Elevated acanthosis nigricans total score also showed strong association with elevated fasting insulin and HOMA-IR. We also found that the neck was the most frequent location of acanthosis nigricans. However, acanthosis nigricans on axilla showed strong association with elevated fasting insulin and HOMA-IR. Estimation of scales and locations of acanthosis nigricans could be useful as a clinical alternative for determining hyperinsulinemia and insulin resistance in obese children.

‘oamibyeo’ a mid-late maturing ecotype with high amylose content in kernels, was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station(NYAES) in 2000 and released in 2001. This variety was derived from the three way cross of Milyang 95//Kimcheonaengmi/2*Ilpumbyeo (in 1992 summer) through the pedigree breeding method and designated as ‘ilyang 168’in 1997. The heading date of ‘oamibyeo’was Aug. 18 in ordinary season with culm length of 85 cm. However, ‘oamibyeo’showed susceptible to bacterial leaf blight, stripe virus and leaf blast disease. The amylose content of ‘oamibyeo’in milled rice kernels is about 26.7% with translucent and clear in chalkness. Thus, ‘oamibyeo’is expected to be used as a source grain for rice noodle industries. The milled rice yield potential of ‘oamibyeo’is about 5.38 MT/ha in local adaptability test of three years and it would be adaptable to Yeongnam plain of Korea.
