남다른 철학과 포부로 육용종계를 사육하는 충북 보은 소재 한국농원(대표 이순구) 이성욱 관리이사를 만났다. 한국농원은 2006년 계사 4동의 농장을 인수하여 계사를 확장, 현재 2만평 부지에 150m와 143m 계사 12동(수탉계사 1동) 규모로 육용종계 12만수를 사육하고 있다. 중추는 전량 외부에서 들여오며, 농장에서는 성계만 사육하고, 부화 역시 위탁을 하고 있다.

출판인 구속사태가 잇따르고 있다. 출판계에서는 문민정부 출범 이후 처음 있는 이같은 출판인 구속이 점차 그 범위가 확대되고 있는 게 아닌가 의아해 하고 있다. 특히 지난 4월 15일 대검찰청이 '좌익출판물에 대한 일제단속'을 전국 검찰과 경찰에 지시한 바 있어, 앞으로 출판물에 대한 국가보안법 적용이 어떤 식으로 진행될지 그 귀추가 주목된다.

The isothermal reduction on $Pt/MoO_3/SiO_2$ at $50^{\circ}C$ demonstrates that the rate of hydrogen spillover is increased as calciantion temperature increases. That is due to the overlayer formation over the surface of Pt crystallites, investigated by TEM and CO chemisorption. It is known that reaction mechanism of skeletal isomerization of 1-butene into iso-butene is composed of 2 step such as formation of carbonium ion and isomerization of methyl group. It is expected that the increase of i-butene yield after calcination at $250^{\circ}C$ is due to increased rate of hydrogen spillover coming from first, overlayer formation over Pt surface and second, chlorine lessoning from $PtCl_x$ precursor.

The flash point is one of the most important physical properties to charaterize fire and explosion hazard of liquid solutions. The maximum flash point of liquid mixture is larger than those of the individual components. In this study, the flash points of 2-pentanol+acetic acid system were measured by Seta flash closed cup tester. This system exhibited the maximum flash point behavior. The flash points were estimated by the Raoult's law and the optimization methods using the van Laar and Wilson equations. The calculated values by optimization methods were found to be better than those based on the Raoult's law.

The flash point is one of the most important properties for characterizing the fire and explosion hazard of liquid solutions. In this study, a Tag open-cup apparatus was used to measure the flash points of two flammable binary mixtures, n-decane + n-octanol and acetic acid + n-butanol. The flash point temperature was estimated using the UNIFAC (Universal Functional Activity Coefficient) group contribution model and optimization method. The experimentally derived flash point was also compared with the predicted flash point. The two methods can estimate the flash point fairly well for the n-decane + n-octanol and acetic acid + n-butanol systems.
