Abstract: The aim of this work is to synthesis zeolite by using coal bottom ash from power plant and used as hydrogen sulfide (H2S) adsorbent to removal H2S from synthetic biogas. The zeolite was synthesized by fusion hydrothermal process of coal bottom ash, which was source of starting materials. Moreover, the obtained zeolite products were used for preparation of polyethylene composite material by using twin-screw extrusion process, polyethylene grafted maleic anhydride (PE-g-MA) as compatibilizer at various PE-g-MA: zeolite ratio (0.5:1, 1:1, 2:1 and 3:1, respectively) and different composition of Titanium Dioxide (TiO2) (0.25, 0.5, 0.75, 1, 1.5 and 2 phr). The results showed that the optimum condition for composite material as PEg- MA: zeolite ratio of 2:1 exhibited the highest adsorption capacity. Moreover, the equilibrium time and adsorption capacity at equilibrium increased with increasing the TiO2 loading. The results suggested that the polyethylene composite material filled with zeolite

Abstract: The International Statistical Classification of Diseases and Related Health Problem 10th Revision (ICD-10) was used extensively in all public hospitals in Thailand. All outpatients and inpatient diagnosis must be coded to ICD-10. Every year 250 million ICD-10 codes were sent to the information department at Ministry of Public Health Thailand. Manual coding by clinical coders could not be completed in some hospitals. Semi-automated ICD-10 coding software is needed to overcome this obstacle. Development of diagnosis directory and algorithm to facilitate physician diagnosis mapping with concepts in ICD-10 is the first step before semi-automated ICD-10 coding software development. The diagnosis directory in this work was built upon two sources of diagnosis list. The first source is the previous diagnosis list from the author research work in 2009. The second source is the diagnosis list built from ICD-10 alphabetical index. Final check of the diagnosis directory was performed by comparison
