해외 정보 - 신규 원전이 채택하고 있는 휴먼 시스템 인터페이스(HSIs) 기술
Hugo, Jacques,Gertman, David 한국원자력산업회의 2016 원자력산업 Vol.36 No.2
최첨단 휴먼 시스템 인터페이스(Human System Interfaces, HSIs) 기술을 연구 분석하여 설계를 거쳐 채택하는 것이 원전 공학 기술의 중요한 요소 중 하나로 자리를 잡고 있다. 미국 아이다호 국립 에너지안보연구소의 Jacques Hugo와 David Gertman은 기술의 사용 환경, 기술 성숙도, 유용성, 인적 성과가 필요한 직무를 기반으로 한 이 새로운 기술이 원전업계가 선택해야 할 바람직한 방안이라고 제안하고 있다.

The question of why leading states recognize other states’ sovereignty hasattracted increasing attention in the IR literature. I analyze the important historicalcase of the sovereign recognition of Japan by the West in the 1890sand in particular by Great Britain, the most important Western power at thattime. I argue that Britain’s decision to fully recognize the sovereignty ofImperial Japan is best explained by a theoretical synthesis of English Schooland rationalist approaches. Britain’s recognition decision was driven by acombination of genuine respect for legal propriety and its perceived materialself-interest. In other words, Britain recognized Japan upon realizing that itwould do well by doing good.

Activated carbon (AC) obtained from peanut shell, chitosan (CH) obtained from crab shell, and prepared chitosan/activated carbon (CH/AC) composite were studied in a batch system for the adsorption of indigo carmine (IC) from aqueoussolution. Characterizations of AC, CH, and CH/AC were investigated by FTIR, SEM, XRD, zero-point charge pHpzc,thermal analysis, surface area BET, and pore-size distribution. Adsorbent weight (0.01-0.1 g), initial pH solution (2-10),initial indigo carmine concentration (10-50 mg/l) and contact time (0-60 min) were used as parameters in the adsorptionequilibrium experiments. Pseudo-second-order kinetic model was found to describe the adsorption process better thanpseudo-first-order kinetic model. Langmuir, Freundlich, and Temkin isotherms applied to the adsorption data reveal that ACand CH/AC best fitted Langmuir and Freundlich models when CH data fitted Temkin model with maximum adsorptioncapacities of 82.64 mg/g for AC, 96.15 mg/g for CH, and 208.33 mg/g for CH/AC at 30 oC. Thermodynamic parameters suchas standard Gibbs free energy (ΔGo), standard enthalpy (ΔHo), and standard entropy (ΔSo) were -23.42 kJ/mol, 10.66 kJ/mol,and 112.40 J/K/mol, respectively for CH/AC. The negative value of ΔGo and a positive value of ΔHo indicate that theremoval of indigo carmine by CH/AC is spontaneous and an endothermic process.
