  • This study was conducted to investigate the growth and physiologycal activitis of Aruncus dioicus var. kamtschaticus (Maxim.) H. Hara under the NaCl treatment conditions (0, 100, 200, 300 mM). After 30 days treatment, the growth and physiologycal activitis were investigated. In the growth of plants, the plant height, leaf width, leaf length and ion level were reduced at NaCl treatments of more than 100 mM. The total polyphenol content was decreased by NaCl in a concentration-dependent manner compared to the control group. The contents of total flavonoids did not show any difference at the concentration of 200 mM and 300 mM. However, the content of total flavonoid decreased compared with that of control. In antioxidant activity, the DPPH and ABTS radical scavenging activity and reducing power activity were decreased by NaCl concentration compared to the control. When changes in the content of NO production was monitored by ELISA, production inhibitory effect was 94.5%, 70%, 63%, 56.9% in NaCl concentration of 0, 100, 200, 300 mM, respectively. The growth, ion level, antioxidant and anti-inflammation activity of Aruncus dioicus var. kamtschaticus was reduced at NaCl treatments of more than 100 mM.

  • The present study aimed to investigate the biological activities and nutritional contents of extracts from three types of edible mushrooms (Pleurotus ostreatus, P. eryngii, and Hericium erinaceus) following different roasting treatments. Roasting by a household multi-oven (HR60) decreased the total polyphenol contents, as well as DPPH radical scavenging and nitrite scavenging activities compared with the fresh samples, and no significant difference was observed between the different roasting times. As a result of rotary drum roasting (CR) treatment, we could observe a decrease in the DPPH radical scavenging activity in all roasted mushroom samples compared with the fresh samples, whereas nitrite scavenging activity increased in roasted P. eryngii and H. erinaceus. Additionally, total polyphenol contents increased significantly in roasted H. erinaceus. In each roasted sample dried by HR60 and CR, the amount of palatable-taste amino acids (e.g., glutamic acid) and sweet-taste amino acids, including glycine, serine, alanine, and threonine, increased in P. ostreatus, whereas the amount of bitter amino acids, including leucine, isoleucine, histidine, valine, and methionine, decreased compared with the fresh samples. In P. eryngii and H. erinaceus samples, we also observed an increase in the amount of palatable and sweet-taste amino acids upon the roasting treatments; however, the amount of bitter amino acids increased simultaneously following the roasting treatments. These results suggest that CR treatment is more effective in increasing the biological activities and nutritional contents, such as palatable and sweet-taste amino acids, compared with HR60 treatment.

  • The Opuntia extract has been traditionally used to treat diabetes, inflammation, and rheumatoid arthritis in oriental medicine. The purpose of this study is to investigate characteristics of biological activity between Opuntia humifusa and Opuntia ficus-indica which is cultivating in korea using cell-free system or cell-based assay. O. humifusa extract effectively inhibited ${\alpha}$-glucosidase activity or improved the immune function, and its biological activity was more effective than O. ficus-indica extract. The scavenging activity of DPPH radical and the inhibitory effect of tyrosinase similarly showed by O. humifusa and O. ficus-indica extract, however neuroprotective effect only showed a tendency to increase compared with control in PC12 cells. Therefore the results suggest that O. humifusa can be a useful agent for treatment of diabetes and immunodeficiency.

  • In this study, the random forest approach was used to predict the national mean rice yield of South Korea by using mean climatic factors at a national scale. A random forest model that used monthly climate variable and year as an important predictor in predicting crop yield. Annual yield change would be affected by technical improvement for crop management as well as climate. Year as prediction factor represent technical improvement. Thus, it is likely that the variables of importance identified for the random forest model could result in a large error in prediction of rice yield in practice. It was also found that elimination of the trend of yield data resulted in reasonable accuracy in prediction of yield using the random forest model. For example, yield prediction using the training set (data obtained from 1991 to 2005) had a relatively high degree of agreement statistics. Although the degree of agreement statistics for yield prediction for the test set (2006-2015) was not as good as those for the training set, the value of relative root mean square error (RRMSE) was less than 5%. In the variable importance plot, significant difference was noted in the importance of climate factors between the training and test sets. This difference could be attributed to the shifting of the transplanting date, which might have affected the growing season. This suggested that acceptable yield prediction could be achieved using random forest, when the data set included consistent planting or transplanting dates in the predicted area.

  • This study aimed to develop high value-added mulberry (Morus alba) vinegar by fermenting mulberry with yeast and acetic acid bacteria, for using it in various foods. To select the optimal strain for mulberry fermentation, different strains were tested and Saccharomyces cerevisiae SRCM101756 and Acetobacter pasteurianus SRCM102419, exhibiting excellent alcohol and acetic acid production ability during mulberry fermentation, were selected for fermentation. Mulberry vinegar was prepared using mulberry wine and the selected acetic acid bacteria, and the physicochemical properties and physiological effects were measured. The pH was 2.98 and total acidity was 4.70% by day 9 of fermentation, establishing the possibility of developing them into vinegars for industrial use. The angiotensin-glucosidase inhibition activity of mulberry vinegar increased from 13.22% to 19.19% in the 100-fold dilution, and from 42.35% to 46.11% in the 50-fold dilution, from before fermentation to after fermentation, respectively. The angiotensin-converting enzyme inhibition activity of mulberry vinegar was found to significantly increase from 44.82% before fermentation to 63.88% after fermentation in the 25-fold dilution. Moreover, a significant increase in pancreatic lipase inhibition activity after fermentation was observed. Thus, mulberry vinegar can be used as a functional material in vinegar and other foods.

  • Der vorliegende Beitrag zielt darauft ab, zwei Perspektiven $f{\ddot{u}}r$ die Kunst bei Kant und Nietzsche und ihre Schlussfolgerungen zu $er{\ddot{o}}rtern$. Kants Kritik der Urteilskraft hat eine enorme Rolle in der Geschichte der ${\ddot{A}}sthetik$ gespielt. $F{\ddot{u}}r$ Kant sollen ${\ddot{a}}sthetische$ Urteile ebenso wie Erkenntnis- und Moralurteile $allgemeing{\ddot{u}}ltig$ sein, obwohl sie auf einem $pers{\ddot{o}}nlichen$ Geschmack beruhen. Die $Allgemeing{\ddot{u}}ltigkeit$ des $Sch{\ddot{o}}nen$ sei $m{\ddot{o}}glich$, weil sie nicht auf dem Gegenstand, sondern auf dem transzendentalen Subjekt basiere. Die $sch{\ddot{o}}ne$ Kunst als Kunst des Genies soll uns wie die $Natursch{\ddot{o}}nheit$ ohne Interesse wohlgefallen. Nietzsches Stellungnahme zu Kants ${\ddot{A}}sthetik$ ist sehr kritisch. Nietzsches erster Kritikpunkt richtet sich gegen das 'interesselose Wohlgefallen'. Gegen Kant behauptet Nietzsche, dass die $Sch{\ddot{o}}nheit$ sehr wohl mit Interesse verbunden ist. Grund $daf{\ddot{u}}r$ ist, dass das $Sch{\ddot{o}}ne$ wesentlich aus dem Willen zur Macht entspringt. Der zweite Kritikpunk Nietzsches liegt darin, dass in Kants ${\ddot{A}}sthetik$ die Moral im Vordergrund steht. Das $Sch{\ddot{o}}ne$ ist $f{\ddot{u}}r$ Kant durch die Moral gerechtfertigt. Nietzsche dreht diese Stellung der Moral zur Kunst um. Der dritte Kritikpunkt Nietzsches ist, dass Kant statt von der Erfahrung des $K{\ddot{u}}nstlers$ (Schaffenden) aus das ${\ddot{a}}sthetische$ Problem zu betrachten, allein vom Zuschauer (Empfangenden) aus ${\ddot{u}}ber$ die Kunst und das $Sch{\ddot{o}}ne$ nachgedacht habe. $F{\ddot{u}}r$ Nietzsche ist die Kunst $prim{\ddot{a}}r$ vom $K{\ddot{u}}nstler$ aus zu verstehen. Nietzsches Physiologie der Kunst ist mit dem Begriff 'Leib' $verkn{\ddot{u}}pft$, d.h. Nietzsche behauptet, dass physiologische und ${\ddot{a}}sthetische$ Prozesse wesentlich $zusammenh{\ddot{a}}ngen$. Die Schlussfolgerung der Physiologie der Kunst lautet: erstens, jeder Mensch ist $K{\ddot{u}}nstler$, sofern er schaffend ist, und zweitens, die Welt selbst ist nichts als Kunst. Nietzsches Physiologie der Kunst hat einen $gro{\ss}en$ Einfluss auf die $gegenw{\ddot{a}}rtige$ Kunst $ausge{\ddot{u}}bt$ und kein anderer Philosoph hat auf die $gegenw{\ddot{a}}rtige$ Kunst nachaltiger gewirkt.

  • The study of Security Martial Arts is classified into nine categories; philosophy, history, education, sociology, psychology, physiology, training science, movement dynamics, and guard practice. The study of the theory and practice of Security Martial Arts should be concerned at first, for the development and progress for the future of Martial Arts. First, theoretical research that can be utilized in the real field should be performed, and such research outcomes are needed to be published as teaching materials and to be shared through various channels. Second, collaborative research of the characteristics of martial arts should be carried out. The Security Martial Arts would achieve a further development if training methods are complemented, and strengths and weaknesses of the events are fully understood. Third, studies for the independence of disciplines should be performed. The study field is derived into nine areas, and each is needed to be developed scientifically and systematically. Accompanied by sustainable study, academic autonomy of Security Martial Arts will be achieved.

  • Purpose: The purpose of this study was to develop syllabuses of basic nursing science subjects (Structure and Function of Human Body, Pathogenic Microbiology, Pathophysiology, and Mechanisms and Effects of Drug) based on learning outcomes. Methods: We developed a 3-phase plan to develop the syllabuses. In the first phase, The Korean Society of Biological Nursing Science (KSBNS) held a workshop in May, 2013 in which professors who are in charge of basic nursing science subjects shared opinions about learning outcomes. As a result, initial prototype syllabuses came out. In the second phase, revised syllabuses based on learning outcomes were presented and discussed in the conference held by KSBNS in November, 2013. In the last phase, a research team who taught basic nursing science subjects finalized the syllabuses during the meetings. Results: Syllabuses of 4 basic nursing science subjects were developed. Conclusion: These syllabuses of 4 subjects need to be disseminated throughout nursing colleges. Further revision needs to be made according to the circumstances and context of each school.

  • Objectives: This study is to analyze Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) and to consider the direction of development. Methods: This study focuses on Acupuncture Methods(鍼法) using Five Transport Points(五輸穴) that Five Phase Theory(五行學說) has been applied as a compound and it is designated Five Phase-Five Transport Points-Acupuncture Method(FPT Acupuncture Method, 五行五輸穴鍼法). Principles, Acupuncture Points(經穴), standards of diagnosis and treatment subjects of FPT Acupuncture Methods used in practices of Korean Medicine (韓醫學) were analyzed through updated literature. Next, the theoretical issues of FPT Acupuncture Methods regarding the composition of selecting exclusively on Five Transport Points(五輸穴) and targeted treatment subjects were investigated. Based upon the investigation, the future direction of development was studied. Results & Conclusions: Firstly, pattern identification and treatment of FPT Acupuncture Methods targeted mostly on Viscera and Bowels(臟腑). However, some showed the tendency to Five Phases Reductionism(五行 還元主義) which attempts to apply Five Phase Theory(五行學說) to symptoms that were not related to Viscera and Bowels(臟腑). Secondly, Five Transport Points(五輸穴) are theoretically related to 'Viscera and Bowels in Concept of Visceral Manifestation(臟象臟腑)'. Thirdly, when the cause of the symptoms exceeds the main therapeutic range of FPT Acupuncture Methods, it is effective to add Acupuncture Points(經穴) excluding Five Transport Points(五輸穴). And also, it is efficient to use Acupuncture Methods(鍼法) that is not based on principles of Five Phase Theory(五行學說). For the accomplishment, further researches on the approaches to apply basic Korean Medical principles such as Three Yin and Three Yang(三陰三陽) into Acupuncture Methods(鍼法) and Acupuncture Points(經穴) are necessary.

  • Last year, the elderly population aged 65 years and over exceeded 14.2 percent of the total population, and Korea has entered the ageing society. At the same time, social interest in improving the health level and quality of life in the elderly has also increased. In particular, pain is one of the most common diseases experienced by middle-aged and elderly people and is one of the factors that closely affect the quality of life. The purpose of this study was to analyze the factors affecting the pain level and pain region of Korean medicine users and the use of Korean medicine in the Korean middle aged and elderly using the 6th Korean Longitudinal Study of Ageing (KLoSA) panel. As a result, the main influencing factors of Korean medical care were subjective factors such as gender, subjective health status, and education level. In particular, half of the middle-aged and elderly who used Korean medicine experienced back and knee pain, and generally complained of low level of pain. This study suggests the need for research and development of Korean medicine that can control and relieve the pain of the middle-aged and elderly.
