A Understanding of Dietary Supplements and Functional Foods in the Occident
서민준,박진한,Seo, Min-Jun,Park, Jin-Han Research Institute of Oriental Medicine 2008 東國韓醫學硏究所論文集 Vol.11 No.-
Dietary supplements are used by more than one-half of the adult US population. By contrast, herbal products in Germany are carefully regulated by the same standards as drugs, and efforts are under way to standardize their regulation in the entire European Union. Most herbal users do not inform their physicians that they are taking these supplements, and most physicians do not inquire. Although some herbal products have clinically proven benefits, it is increasingly apparent that many contain potentially toxic substances, particularly in relation to interactions with drugs. Hence, it is essential that practicing physicians develop a working knowledge of herbals-specifically, about claims for their usage and potential or proven efficacies and toxicities-and that they incorporate such knowledge into the evaluation and management of their patients. By contrast, functional foods-integral components of the diet that are understood to contribute added health benefits-are the subject of intense and widespread research in food and nutritional science. Examples include many polyphenolic substances, carotenoids, soy isoflavones, fish oils, and components of nuts that possess antioxidant and other properties that decrease the risk of vascular diseases and cancer. Practicing physicians are advised to stay abreast of these emerging findings in order to best advise their patients on the value of health-promoting diets in disease prevention.

Objective : In the present study, we assessed the enhancing effect of the fermented Angelicae Gigantis Radix on memory and cognitive function in scopolamine induced amnesia mice. Method : The memory and cognitive enhancing effect of the fermented Angelicae Gigantis Radix was investigated using a passive avoidance test, the Morris water maze test and Y-maze test in mice. Drug-induced amnesia was induced by treating animals with scopolamine. Result : The fermented Angelicae Gigantis Radix significantily reversed the scopolamine-induced cognitive impairments in the passive avoidance test. Moreover, the fermented Angelicae Gigantis Radix also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze. On the Y-maze test, fermented Angelicae Gigantis Radix also significantily reversed the scopolamine-induced cognitive impairments in mice. Conclusion : The fermented Angelicae Gigantis Radix possesses the anti-amnestic and cognitive-enhancing activities related to the memory processes, and these activities were parallel to treatment duration and dependent on the learning models.

Objective : The purpose of this study was to provide the information about Bojungikki-tang by domestic papers and theses. Method : Domestic papers related to Bojungikki-tang were reviewed and analyzed. These papers were classified by year, research method, experimental method, and subject. Result : The following results were obtained in this study. 1. The study of Bojungikki-tang started from 1984 and continued steadily. 2. The domestic papers about Bojungikki-tang were 47 volumes. Among them, there were 26 volumes since 2000. 3. Classified by research method from the year 2000, 20 experimental studies, 4 clinical experiments, and 2 documentary researches. 4. Classified by experimental method from the year 2000, 10 studies used mouse in vivo experiment and 4 studies used rat in vivo experiment and 6 studies used each cell in vitro experiment. 5. Classified by subject from the year 2000, papers related to immune enhancing effect, nerve and mental system, radiation protection effect, anti-allergy, anti-inflammatory, anti-cancer, remedy of diabetes, skin protection and so on. Conclusion : Many papers of experimental studies, clinical experiments and documentary researches related Bojungikki-tang are included in domestic journals. Bojungikki-tang is being researched variously in immune enhancing effect, nerve and mental system, radiation protection effect, anti-allergy, anti-inflammatory, anti-cancer, remedy of diabetes, skin protection and so on. However, more clinical studies on Bojungikki-tang are needed.
태양 에너지 발전 효율 증대를 위한 PVT 패널 내부 유동에 관한 실험적 연구

Renewable energy generation has increased and will increase about 10 times in 30 years. Since solar energy accounts for a significant part of renewable energy production, increase of efficiency is important. There are 2 ways to use solar energy, photovoltaic and solar thermal panel. The combination of those ways is called photo voltaic thermal (PVT) panel which simultaneously obtains electricity and thermal energy from the sun. This study deals with a PVT panel composed of a phase change material (PCM) and a heat exchanger in PV panel. The water is used as heat exchanger fluid and change in flow rate causes change in thermal energy output. In this experiment, by comparing between 30LPM and 60LPM flow rate, 60LPM flow rate results in 7.3 % high in thermal energy output.
