This article illustrates the temperature dependent spreading and receding characteristics of a Newtonian and a non-Newtonian droplet impact on a heated solid surface at different Weber numbers with surface temperatures. To make non-Newtonian droplets, a xanthan gum solution was used with different concentrations. From a high-speed camera images, spreading and receding diameters were captured during the impact process. For impact velocity and solid surface temperature, distinct differences in spreading and receding motions were found between Newtonian and non-Newtonian droplets. If a solid surface temperature increases, the maximum spreading diameter slightly increased at DI-water droplet whereas the maximum spreading diameters of xanthan gum droplets were similar for all surface temperatures. This is due to viscosity change on thin liquid lamella contact with heated surface. The receding phenomena could be clearly distinguished on the heated surface. The retraction rate of a xanthan gum droplet increased by increase Weber number whereas DI-water droplets were constant. Because both shear thinning and heat affected liquid lamella influenced a droplet receding, shear viscosity of the xanthan gum droplets decreased faster than the DI-water.

생산원가의 절감을 위해서 육티탄산칼륨 섬유는 융제법으로 원료물질을 금홍석, 공업용 K₂CO₃, 그리고 공업용 K₂MoO₄를 사용하여 제조하였다. 이 육티탄산칼륨 섬유를 얻기 위한 최적 조건은 반응온도 1050℃, 반응시간 5hrs, K₂CO₃에 대한 금홍석의 몰비 5.5 그리고 K₂CO₃와 TiO₂ 혼합물에 대한 flux의 몰비 4.0이었으며, 적절한 해섬처리 조건은 40배수의 물에 대해 8시간이었다. 이상의 조건으로 합성한 육티탄산칼륨 섬유는 평균 직경 0.5㎛, 평균길이 17㎛였다. 또한 육티탄산칼륨 섬유는 1N HCl에서 60일 후에도 안정하였다. Fibrous potassium hexatitanate whisker was produced through the flux method using a mixture of the natural ruble ore, industrial K₂CO₃ and industrial K₂MoO₄ in an attempt to reduce the fabrication cost. The optimum condition for the synthesis of potassium hexatitanate whisker was the reaction temperature of 1050℃, reaction time of 5 hrs, ruble ore mole ratio to K₂CO₃ of 5.5, and flux mole ratio to mixture (K₂O+nTiO₂) of 4.0. Also the proper water leaching condition for removing of K component was a multiful of 40 for water quantity and 8 hrs for leaching time in boiling water. In this condition, synthisized potassium hexatitanate whisker was a fibrous crystal of 17㎛ of average length and 0.5㎛ of average diameter. Potassium hexatitanate whisker was stabilized after 60 days at 1N HCl.

Urinothorax is rare cause of pleural effusion. Urinothorax should be considered when pleural effusion occurs in patients with urinary tract obstruction accompanied by retroperitoneal urinoma. It has been reported in patients with trauma, malignancy, kidney biopsy and renal transplantation. Most cases are diagnosed retrospectively by promt resolution of symptoms after relief of urinary obstruction. But dia- gnosis can be made based on clinical suspicion, radiological findings and biochemical analysis of the effusion and most important finding is the pleural level of creatinine is higher than the serum level. We experienced right pleural effusion in autosomal dominant polycystic kidney disease hemodialyzed. The patient had right urinoma in the retroperitoneal space before pleural effusion developed. After 3month, he complained acute dyspnea. There was no effect in resolving effusion by lowering dry weight. We thou- ght alternative diagnostic possibility, urinothorax and checked the pleural fluid to serum creatinine ratio. Finally concluded that pleural effusion was urinothorax secondary to remnant left polycystic kidney rup- ture and tried left nephrectomy. The patient showed reduction of pleural effusion. It is important to alert physician to this condition and to avoid the other invasive diagnostic study.

The consumer awareness concerning coffee beverages has increased in Korea. The objective of this study was to optimize the roasting conditions of coffee bean for consumer`s attribute. The optimal roasting conditions for Colombian coffee beans were analyzed by using a central composite design with a quadratic polynomial model by response surface methodology (RSM). The experimental conditions for coffee bean roasting were 194.82℃~250.00℃ and 7.93~22.07 minutes. The responses of sensory attributes, physicochemical and physical properties were analyzed with RSM. The width, length and height of green beans increased when the beans were roasted. The higher degree of roasting gave the higher pH and solid contents but the lower total acidity and total phenolic compounds. In sensory tests, the roasting temperature and time had a significant effect on the flavor score. The optimum roasting condition of Colombian coffee bean predicted for maximizing the length, width, solid contents, total phenolic compounds and flavor score were 20 minutes at 225℃ by RSM.
