Background: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. Methods: We conducted a multicenter, prospective, non-interventional study. Patients with $CHADS_2{\geq}1$ and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. Results: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had $CHADS_2{\geq}2$ and 83.6% had $CHA_2DS_2-VASc{\geq}2$. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. Conclusion: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

This study examined radiation detection characteristics of spices (cumin, caper and turmeric), other small fruits (hut-gae berry and boxthorn), and pollen extract product. Each samples were irradiated at dose of 1, 5, and 10 kGy and analyzed by the thermoluminescence (TL) and electron spin resonance (ESR) methods. To compare between non-irradiated and irradiated food, all samples were irradiated with $^{60}Co$ gamma-ray source. In TL analysis, most of samples could be applied to detect irradiated foods because of showing TL ratio above 0.1. The glow curves examined by TL method were estimated in the range of $150{\sim}250^{\circ}C$ in irradiated samples. In ESR measurements, the intensity of ESR signal (single-line) increased as the increase of irradiation dose. In particular, the specific ESR signals of irradiation-induced radical were detected in hut-gae berry and pollen extract product. As a results, it is considered that TL and ESR methods can be used to detect both hut-gae berry and pollen extract product. But cumin, caper, turmeric and boxthorn irradiated with gamma ray could be detected only by TL method. It is concluded that TL and ESR methods are suitable for detection of irradiated samples and a combined method is recommendable for enhancing the reliability of detection results.

This paper analyzes the thesis classification of the "Korean Philosophy Journal" and the subject and characteristics of two representative scholars of the Research Society in commemoration of the 30th anniversary of the establishment of the 'Korean Philosophy History Research Society'. The "Korean Philosophy Journal" was published from the 1st edition in 1991 to the 55th edition until November, 2017, and introduced a total of 582 papers. In the meantime, the 'Korean Philosophy History Research Society' became a registered place after being nominated by the Korea Research Foundation. Among the 582 chapters, 297 papers deal directly with Korean philosophy, and 174 papers on Chinese philosophy. Among the Korean philosophical theses, the most popular one was the 198th issue, and the Chinese philosophical thesis was the most popular with the subject of theology. Among the Korean philosophers, Chung Yak - Yong and Chinese philosophers Chu Shi were the most studied. Among the writers who participated in the "Korean Philosophy Journal", 203 were all of them. Among them, Lee Sang Ik published the most articles with 28, and Choi Young Sung was the second with 23. Based on Lee Sang Ik 's thesis 28, Lee Sang Ik is a well - known neo - Confucianism scholar. His research is based on the theory of neo - Confucianism and the theory of secularism. On the one hand, he establishes his own moral theories and criticizes other moral theories. On the other hand he establishes his own governing theory and criticizes other governing theories. And theoretical proposals on various problems in modern society Based on Choi Young Sung 's thesis, 23, Choi Young Sung is the best researcher in the field of studying in Korea. His research focuses on correcting mistaken perceptions and descriptions in the history of study abroad in Korea, and developing the undeveloped parts. In addition, I am looking for a new perspective on the history of studying in Korea. In addition, he has been studying the philosophical thought of Choi Chih Won in order to establish a philosophical foundation for approaching the history of thought rather than just the study of the history of thought. The "Korean Philosophy Journal" has been advanced in quantity and quality, and has developed quantitatively and qualitatively. Revitalization of the SungKyunKwan university Korean Philosophy Department is indispensable for the continuous development of "Korean Philosophy Journal" and 'Korean Philosophy History Study Society' and to create excellent scholars.

Along with Hujiwara Seika(藤原惺窩), Hayashi Razan(林羅山) is called the founder of the Japanese Confucianism in the Eto(江戶) era. And it is necessary for us to grasp that how Razan understand the theory of I-Ki(理氣論), then we can investigate the characteristics of his thought. In ordinary, people understand that the theory of I-Ki, as a completed view of the world, is integration of the structure of theory of the neo-Confucianism. So a certain thinker's ideological attitude is determined according to how people understand the theory. And then we can grasp the structure of his view of the world and human. Therefore, the purpose of this paper is to study how Razan had understanded the I(理) and Ki(氣). In spite of a scholar of Zhu Xi(朱熹), Razan didn't accept Zhu's view of I-Ki, he seem to lean toward the view of Wang Yangmings'(王陽明) in the his early learning days. But that doesn't mean he is a scholar of doctrine of Wang Yangming. When he meets the logical contradiction under the process of investigating the problem of Sein and Sollen, he just only to explain it with logic of Ki(氣) which is closed by mind. Meanwhile if we suppose I(理) is pure goodness and there is no things outside of I(理), if so Razan doubts about that where is the root of evil and he try to investigate the answer. In his latter years, Razan takes Zhu Xi's doctrine again get out of the mental attitude to the view of I-Ki(理氣). The outcome of precedent study about Razan points a fact that Razan needs a little more digging into the ieda of 'Fact and Sollen' which had been the reason of ideal confusion of him. But his ideal confusion is not the point of issue. Point is that Razan had understanded I-Ki(理氣) with monistic of Shim(心) in his early years. As a result, that bring about the outcome which exclude ontological thinking, and had come to grips with aspects of Sollen of all things in understanding of the doctrine of Zhu Xi. And I think that is the clue to understanding of Razan's learning.

Fruit wine from Acanthopanax sessiliflorus(A. sessiliflorus) including many pharmacological components was manufactured and its functional properties were investigated. The fruit part of A. sessiliflorus contained 75.74${\pm}$0.49%(w/w) moisture, 12.51${\pm}$1.23%(w/w) crude protein, 4.20${\pm}$0.51.%(w/w) crude fat and 5.21${\pm}$1.64%(w/w) crude ash. Minerals of fruit were potassium(12.94${\pm}$0.08 mg/g), calcium(1.53${\pm}$0.06 mg/g) and magnesium(1.12${\pm}$0.05 mg/g). Initial soluble solid and fermentation temperature were 24-30$^{\circ}$Brix and 20${^{\circ}C}$ for manufacturing fruit wine from A. sessiliflorus. When initial soluble solid of a must was adjusted to more than 30$^{\circ}$Brix, ethanol production was suppressed slightly. The polyphenol content of the fruit wine fermented at 20${^{\circ}C}$(125.24${\pm}$1.86 mg/mL) was higher than those at 25${^{\circ}C}$(99.69${\pm}$2.11 mg/mL) and 30${^{\circ}C}$(95.55${\pm}$1.54 mg/mL). Electron donating activities of wines fermented at 20, 25 and 30${^{\circ}C}$ were 85.9${\pm}$2.3, 55.7${\pm}$2.5 and 55.2${\pm}$3.4%, respectively. The content of eleutheroside B increased up to 146.58${\pm}$4.10 $\mu$g/mL during fermentation. There was no significant effect of fermentation temperature on eleutheroside B content. The fruit part of A. sessiliflorus can be used as a valuable resource for development of nutraceutical foods.

'Younghan' (Hordeum vulgare L.), a winter barley for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute of Crop Science, Rural Development Administration in 2008. It was derived from a cross between $F_1$['YB3433-3B-5'/'YB3135-3B-2-3'] and 'YB3135-3B-2-3'. 'SB971305-B-B-B-4-4' line was selected for its earliness, resistance to disease and good agronomic characteristics. The promising line showed both high yield and lodging resistance in the yield trials in Iksan in 2004 to 2005, and designated as 'Iksan420'. The line was subsequently evaluated for winter hardiness, earliness, and yield at eight locations throughout Korea for two years from 2007 to 2008 and finally named as 'Younghan'. It has the growth habit of IV, erect plant type, green leaf and thick culm in diameter. Its heading date was April 24, and the maturing date was May 25 in paddy field conditions, which were one day earlier than those of the check cultivar 'Youngyang'. The cultivar 'Younghan' had better winter hardiness, and resistance to lodging and BaYMV than those of the check cultivar did. The average forage dry matter yield of 'Younghan' was approximately 12.0 MT/ha in adapted region. 'Younghan' also showed 8.5% of crude protein content, 27.2% of ADF, and 67.1% of TDN, including higher grade of silage quality for whole crop barley. This cultivar would be suitable for (area with daily minimum temperature in January) above $-8^{\circ}C$ in Korean peninsula.

This study was conducted to investigate the efficiency of water quality remediation and the inorganic ion removal characteristics by floating plant; water lettuce (Pistia stratiotes L.) in a batch reactor. Water lettuce can be used to remove N and P and other inorganic nutrients, by consuming them in the form of plant nutrient. The highest nutrient absorption of water lettuce was $112.5meL^{-1}\;N$ in Sonneveld-2S, $56.6meL^{-1}\;N$ in Sonneveld-1S, $31.8meL^{-1}\;N$ in sewage and P value was also the highest in Sonneveld-2S as $15.6meL^{-1}$ and in sewage as $5.0meL^{-1}$. These results indicated that using water lettuce held some promise in the context of purification of eutrophication. Also water lettuce had a preference for absorption N. Under Sonneveld-2S treatment, nitrogen percentage was the highest in plant tissue due to the highest concentration of nitrogen and removal by water lettuce. Under sewage, percentage of total N in both plant parts was high. Both above and underground parts, P percentage was less than N. It might be due to the fact that the absorption amount of P was less than N by water lettuce. It meaned that the ability of N removal by water lettuce was higher than that of P, relatively. In summary, these results show that the use of this plant was a viable option.

To investigate the characteristics of plant growth and flower quality of gerbera 'Sunny Lemon' by amount of nutrient solution, young seedling plants, 'Sunny Lemon' were transplanted to rock-wool and medium of peat moss and perlite mixed with 1 to 2 and they were acclimatized in greenhouse during about 1 month. Nutrient solution supplied to the plants is sonneveld solution of 1/2 concentration and treatments launched June 24, 2010 when average plant height was $20{\pm}1cm$. Nutrient contents as a standard for starting point of irrigation by time domain reflectometry (TDR) were determined with 60-65%, 70-75%, and 80-85%. Results of growth during vegetative growth, plant height, leaf width and leaf number increased by 10% in rockwool, but they were not significantly different. As for plant growth depending on nutrient content, 80-85% treatment showed the highest values. Leaf number increased by 60%, and leaf width and plant height had a about 40% increase than initial growth. Effectiveness for flower quality, yield and days to flowering were superior when nutrient content of media was higher than in the others. Especially, average days to flowering in 80-85% content was advanced by 7-10 days compared to the day in 60-65% treatment. The total amount of nutrient supply per plant was higher in mixed medium than in rockwool, but change patterns of EC and pH were enhanced in rockwool. Based on our results, we recommended that growth, cut flower, and yield of gerbera 'Sunny Lemon' were more effective when nutrient content of mixed medium was maintained at 80-85%.
