Aluminum alloy (3003) can be dissolved during hydration process with hot tap water. In order to increase the stability of aluminum alloy, it was pretreated with anodization and phosphoric acid before hydration process. The effect of pretreatment on the surface property changes was analyzed with X-ray Photoelectron Spectroscopy (XPS) and Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) and their results supported that the increase of hydroxyl group (-OH) on the surface formed during anodization and phosphorous acid treatment prevented the dissolution of aluminum alloy during hydration process at high temperature.

This study was accomplished to examine possibilities to apply Korean medicine to breamaking. Extracts of Chungpesagan-tang prepared by the prescription of Korean medicine were used for baking, instead of water among ingredients of baking. Effects of addition of extracts of Chungpesagan-tang on various baking properties were analyzed during the process of baking. Changes in pH values and volumes of doughs during fermentation and pH values of bread showed no differences among samples. Loaf volumes and specific loaf volumes were increased somewhat on addition. The values of cohesiveness, springness, gumminess and brittleness of breads, which were measured by rheometer, were increased on addition while those of hardness were decreased a little. Lightness values of sections of loaves were decreased on addition, but their color differences were increased largely on color difference meter. There were nearly little differences among samples in all the values of parameters of external and internal characteristics and eating qualities of breads by sensory evaluation. Re-purchasing attitude of pullman bread added with Chungpesagan-tang had a high in the gender and age.

In general, individuals with advanced age are often associated with a number of chronic illnesses and, thus, polypharmacy becomes therapeutic necessity for these patients. In these cases, the inappropriate prescription, a problem associated with the polypharmacy, may lead to the complication in the pharmacotherapy, the increase in the unnecessary financial burden and the increase in the number of incidence of toxic/adverse reactions. The objectives of the study are to evaluate the status of polypharmacy in patients over 65 years of age in Seoul National University Bundang Hospital, and to formulate way(s) to alleviate the problem. Using the Electronic Medical Record (EMR) system of the hospital, various demographical and therapeutic variables (i.e., the gender, age, medical department, number of medicine, frequency of prescription for a given therapeutic class and frequency of inappropriate prescription) were complied during the 6 month period (viz, January 1st 2004~June 30th 2004) for patients over 65 years of age having 4 or more medicines per each treatment. In addition, the frequency of the duplication of therapeutics in prescriptions was determined in the departments of cardiology and neurology. The number of patients in the category was 4,378, accounting for 24.2% of patients over 65 years of age. The average age was 72.4 years (range of 65 to 96 years) while 57.6% (i.e., 2,521 patients) of the group was female patients. Based on the Beers Criteria, 0.94 % of the patient group was found to receive the medications always be avoided by elderly patients. For 3,399 patients who attended both departments, 13 patients were prescribed with the therapeutic duplication. Considering the fact the elderly patients are likely to be associated with the deterioration in the physiological and psychological functions, the outcome of the toxic/adverse reaction may become significantly amplified. Therefore, these observations indicate that an early warning system has to be implemented to alleviate the incidence of inappropriate prescription such as therapeutic duplication, overdose and/or potential drug-drug interaction.
