For the effective use of soymilk residue(SR), by-product of soymilk production, Wheat Doenjang made of Wheat flour-SR koji(WFSR koji) and soybean was manufactured. As the results, the contents of reducing sugar were increased till 50 days in all samples and decreased thereafter during aging of the mash. The contents of amino nitrogen were prominently increased till 50 days, but increasing ratio was slightly slowdowned thereafter. The higher the mixing ratio of SR was, the less the contents of reducing sugar and amino nitrogen were. The contents of total acid were also prominently increased till 40 days, but were slowdowned thereafter and the differences among all treatments were small. As the mixing ratio of SR was increased, the yellowness and the redness were increased and the lightness was decreased in 80 days aged samples. In sensory evaluation of 90 day aged samples, control [WFSR koji 100 (WF: SR ; 100 : 0), soybean 100] was the best in soy sprout Doenjang soup. As the mixing ratio of SR was increased, the taste was dropped slightly but no significant differences were obtained between control and sample A[WFSR koji 125 (WF: SR ; 100 : 25), soybean 75], sample B[WFSR koji 150(WF: SR ; 100 : 50), soybean 50] and sample C[WFSR koji 175 (WF: SR ; 100 : 75), soybean 25], sample C and sample D[WFSR koji 200(WF: SR ; 100 : 100), soybean 0].

Objective : The purpose of this study is to present the epidemiological data on patients with a stroke admitted to Department of Acupuncture & Moxibustion, Oriental Medical Hospital Kyung Hee University and to investigate the difference between preceding diseases of stroke. Methods : We reviewed medical records of 700 patients with a stroke admitted to Department of Acupuncture & Moxibustion, Oriental Medical Hospital, Kyung Hee University. Results: The incidence of cerebral infarction was 6.7 times that of cerebral hemorrhage. The incidence in males was 1.28 times of that in females. The incidence of stroke increased with aging and more cerebral hemorrhage occured in lower age group than cerebral infarction. There was higher morbidity in October, during the changing of the seasons, than any other months. Hypertension was the most common preceding disease followed by diabetis mellitus, heart disease, hyperlipidemia, and according to Odds's ratio for Male/Female, the probability of having preceding diseases was higher in females than males. In cerebral infarction, MCA territory was the most frequent lesion sites. Of the cerebral hemorrhage, basal ganglia (60%) was the most commonly involved site which was followed by thalamus(33.3%), cortex (3.3%) and subcortex (2.2%). The most common symptom accompanied by stroke was motor dysfunction which was followed by verbal disturbance, urination disorder and dysphagia. Conclusion : This study showed the trends of stroke in Oriental medical center. We expects that Multicenter cooperative and prospective study including Oriental Medicine will be inspired by this study for establishing more accurate chacteristics of stroke in Korea in the future.

In Korea, elderly population aged 65 and older are about 5.0% and 10.7% in 1990 and 2009, respectively. Since elderly people may experience physiologic changes with aging and their pharmacodynamic and pharmcokinetic parameters also have been undergone changes, several adverse drug reactions can occur more frequently than young people. Especially, neuropsychiatric adverse drug reactions such as delirium and drowsiness endanger elderly patients more. The purpose of this study is to evaluate the outpatient prescriptions using drug causing delirium and drowsiness in elderly patients aged 65 and older. We retrospectively reviewed prescriptions for elderly patients collected from four community pharmacies from January 2nd to February 1st, 2010. One pharmacy was located closed to a general hospital, and others were located closed to a internal medicine or an ENT clinic. The each number of the collected prescriptions was followings; Group A (n=496) from internal medicine department of a general hospital; Group B (n=44) from ENT department of general hospital; Group C (n=144) from internal medicine clinic; Group D (n=110) from ENT clinic. In result, in Group A, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.38 In Group B, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.09 In Group C, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.51. In Group D, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.72. Especially, in Group D, the percentage of prescription that drugs causing delirium or drowsiness per Rx prescribed more than 3 is 52.73% In all the 4 groups, over the 60% of drugs causing delirium and/or drowsiness per prescription of elderly patients were prescribed. It means elderly patients take 2 drugs causing delirium and/or drowsiness among 3 drugs, which is very serious. Frequently prescribed drugs causing delirium and/or drowsiness were followings; GI agents, antitussives & expectorants, histamine H1 antagonist, analgesics, antibiotics. Among these drugs, GI agents was high raking in all the 4 groups, and pharmacists should caution elderly patients when counseling. In the internal medicine groups (Group A,C), drugs concerning chronic diseases were prescribed frequently. In conclusion, pharmacist's role is important. Pharmacists are well informed of the drugs causing delirium or drowsiness and it is important to explain about ADRs slowly and easily to the elderly patients that receive drugs causing delirium or drowsiness. And institutional device is needed. For example, when doctors prescribe drugs for the elderly patients, message is needed that supply some informations about drugs causing delirium or drowsiness.

This study is a qualitative analysis that conducted a focus group interview to analyze the experiences of daily life of the elderly living alone and their chronic diseases management, and to explore the meaning, nature, and difficulties associated with. The subjects of this study were elder who lives alone without cognitive impairment and over 65-year-old. There were total 31 people and divided into 5 groups and they had 60 minutes interview. By this study, there were four themes of 'difficulties of daily life', 'suffering from chronic diseases', 'fear of the future', 'acceptance of life'. In conclusion, the elderly living alone felt difficulty in daily life due to physical aging and chronic illnesses, and they felt that they were accepting life at the same time while feeling the fear of the future situation. Therefore, in order to improve the life satisfaction and life quality of elderly people living alone, it is necessary to provide institutional devices that enable daily life such as meals and laundry to be maintained and to develop of an intervention program in order to maintain physical health. In addition, an intervention program should be developed to reduce the fear of future uncertainty and positively accommodate the life.

Waxes currently used as a coating material to preserve surfaces of outdoor iron sculptures tend to face lower coating strength and efflorescence due to the aging from air pollution and acid rains. Consequently, they are subjected to repeated corrosions shortly after the treatment. And the sculptures face the problem losing their original nature because of the changes of colors and lusters, so this convergence study aims at developing wax with better performance than the existing materials. For this reason, the study identified the effects of physical property using the environmental experiments such as the tests of salt spray and gas corrosion as well as the analysis of luster level and thermo-gravimetry. As this study result, the developed ISC wax showed the excellent blocking effect from salt water and coating durability more than five times compared with the existing waxes, better acid resistance by two-four times, sun block effect by 2-10 times, improved luster variance by 3-16 times, improved thermo-stability and durability by 0.5-5 times, and therefore demonstrating far better coating effect than the existing waxes. In the light of these findings, this study contributes for this new development which can replace the existing waxes used so far in order to preserve the outdoor iron sculptures.

Skin is continously exposed to ultraviolet (UV) radiation, the major cause of skin disorders including skin aging. Chlorophylls were well known as photosensitizer initiating subsequent chemical reactions such as photooxidative deterioration of cellular structures. This experiment was designed to elucidate the effects of $\beta$-carotene and ascorbic acid with chlorophylls on UVB-induced photooxidation in linoleic acid emulsion model system and skin homogenate of ICR mouse. In linoleic acid emulsion model system, the addition of chlorophyll and $\beta$-carotene accelerated the photooxidation, while high concentration of ascorbic acid prevented. The combination of chlorophylls, $\beta$-carotene and ascorbic acid, which concentrations are simplified from mustard leaf kimchi, prevented UVB-induced photooxidation. Although single treatment of $\beta$-caretene accelerated photooxidaiton, $\beta$-caretene acted as antioxidant in the combination with ascorbic acid. Similarly the addition of individual chlorophylls and $\beta$-carotene accelerated the UVB-induced photooxidation in skin homogenate of ICR mouse. 50 ppm of ascorbic acid did not show the any preventive effect, however 500 ppm of ascorbic acid effectively prevented the oxidation. Photooxidation was prevented in the combination of chlorophylls and $\beta$-carotene with 500 ppm of ascorbic acid and concentration rate of ascorbic acid plays an important role in the prevention of UVB-induced photooxidation.

The growth inhibition by nisin-Producing lactococci against Bacillus subtilis and its application to doenjang fermentation were investigated. Lactococcus lactis subsp. lactis IFO 12007, L. lactis subsp. lactis ATCC 7962 and L. lactis subsp. lactis ATCC 11454 were used as nisin-producing lactococci. All of three strain rapidly proliferated to more than 10$^{9}$ CFU/g in steamed soybeans. Only L. lactis subsp. lactis IFO 12007 was in steamed soybean without any pH decrease. In spite of the mild decrease in pH, the growth of B. subtilis was completely inhibited; no living cells were detected in a soybean sample inoculated with 10$^{6}$ CFU/g and incubated for 24 to 72h. The L. lactis subsp. lactis IFO 12007 was applied to doenjang fermentation as a starter culture. It produced high nisin activity in steamed soybean, resulting in the complete growth inhibition of B. subtilis, which had been inoculated at the beginning of the meju fermentation, throughout the process of doenjang production. Over-acidification, which is undesirable for doenjang quality, was successfully prevented simply by adding salt which killed the salt-intolerant L. lactis subsp. lactis IFO 12007. Furthermore, the nisin activity in doenjang disappeared with aging.

In our previous report, we indicated that not only BSA but also BGG played an important role in the allergenicity of beef. In this study, the effect of heat or high-pressure treatments to beef extract on the SDS-PAGE patterns was examined. The antigenicity of each treated samples was also investigated by Western blots assay with the sera of BGG-positive beef allergic patients. The BGG band and its antigenicity slightly disappeared but not generally in $100^{\circ}C$ group, indicating $100^{\circ}C$ treatment is not sufficient to totally eliminate the antigenicity of beef allergens. Compared with BGG band, BSA band significantly disappeared in SDS-PAGE with $100^{\circ}C$ treatment, indicating BSA is more heat- sensitive than BGG. When the beef extract was heated at $120^{\circ}C$, not only BSA but also BGG bands was largely disappeared in both SDS-PAGE and Western blots. High pressure (HP) treatment even at 600 MPa did not affect SDS-PAGE and Western blots pattern of BSA. On the contrary, BGG treated with HP showed visible changes in SDS-PAGE. 600 MPa treatment significantly reduced the antigencity. Interestingly, these behaviors of BGG were not found in the same experiments with pure BGG treated with HP. From these results, it was speculated that some kinds of proteolytic enzymes in beef extracts were involved in the BGG molecular degradation by HP treatment. The aging experiments of beef extracts treated with HP supported this hypothesis. Further studies are needed to clarify the function and working mechanism of enzymes associated with BGG degradation in beef extracts by HP treatment.
