산뽕잎, 은행잎 및 혼합차의 침출시간에 따른 항산화 활성을 DPPH 라디칼 소거 활성과 FRAP 방법으로 조사하였으며, 총 페놀 화합물의 함량은 Folin-Ciocalteu법, 플라보노이드 함량은 HPLC로 분석하였다. 침출시간에 따라서 DPPH 라디칼 소거활성과 FRAP 활성은 은행잎차, 혼합차, 산뽕잎차 순으로 높게 나타났다. 총 페놀 성분 함량은 은행잎차, 혼합차, 산뽕잎차 순으로 높았으며 산뽕잎에 은행잎을 2:1로 혼합하였을 때 항산화 활성이 증가하였다. 침출시간 3분 정도에서 산뽕잎차 및 혼합차는 비교적 항산화 활성이 높았으며 은행잎차는 6분 까지 활성이 증가하였다. HPLC로 분석한 플라보노이드 성분 함량은 quercetin이 모든 차에서 가장 함량이 높았으며, 은행잎차, 혼합차, 산뽕잎차 순으로 플라보노이드의 총 함량이 높게 나타났다. 제조한 침출차 들의 항산화 성분 함량과 항산화 활성의 상관계수는 0.87 이상으로 상관성이 상당히 높았다. The antioxidant activities and flavonoid contents of the mulberry leaves and the ginko leaves teas were investigated. The antioxidant activities were examined by FRAP and DPPH radical scavenging assays, and total phenolic content and the flavonoid contents by HPLC were also determined. The ginko leaves tea showed the highest antioxidant activities and antioxidant contents, while the wild mulberry leaves tea showed the lowest. The antioxidant activities of the mixture tea of wild mulberry leaves and ginko leaves were increased more than the wild mulberry leaves tea. The flavonoid contents of the leaves(ginko, wild mulberry and mixture) powders were higher than those of infusion teas. Compared with wild mulberry tea, the mixture tea showed a little increase of flavonoid contents. The total phenolic contents and the flavonoid contents of the teas showed good correlations with their antioxidant activities, such as FRAP and DPPH radical scavenging activities(). The antioxidant capacities of wild mulberry leaves tea could be enhanced by the addition of the ginko leaves.

This is a survey on farming activities of intensive major course's graduates of Korea National College of Agriculture and Fisheries(KNCAF). Above all, major characteristics of graduates of intensiv major course cases are as follows. First, They make an effort to secure of agriculture competitiveness through an increase in farm size, and then strive for their specialty. Second, They are leading value based agriculture through an innovations in techniques. According to analysis results, intensive major course's examples have the following features: aim at environmentally-friendly agriculture, actively introduction of new technology, continued research activity, community reinvigoration and leading development of agriculture through active network. Finally, This result in various certifications and awards(environment friendly certification, HACCP certification, non antibiotic/pesticide-free certification, organic certification etc.). Therefore, there are necessity of various intitutional and political supports in order that they grow the core people and leader of farm village.

삶의 참된 끝맺음, 웰엔딩(Well-ending)에 관한 이해 - 유가사상을 중심으로

황인욱 경기대학교 인문학연구소 2012 시민인문학 Vol.23 No.-

최근에 부각되고 있는 현대인들의 관심사 중 하나는 죽음의 질적 차원을 드높이는 데 있다. 이는 삶을 어떻게 살아가는지에 대한 관심이 아니라, 죽음을 어떻게 맞이할지에 관한 고려로부터 비롯된다. ‘웰다잉(Well-dying)’, 또는 ‘웰엔딩(Well-ending)’이라는 문화 운동 코드의 출현은 삶의 질 못지않게 죽음의 질까지도 고려하고자 하는 관심이 반영된 것이다. 유행처럼 번졌던 웰빙 운동처럼, 이들 구호는 사람들의 시선을 끌만큼 충분히 매력적이다. 하지만 이러한 매력적인 구호가 지닌 취지에 비해 아직까지 실천을 진지하게 유발시킬 만 큼의 견고한 이론적 토대가 마련되지 않은 것은 사실이다. 유가 사상의 죽음관은 이러한 이론 내용들 중 하나일 수 있다. 특히, ‘웰엔딩’의 뜻을 엄밀하게 이해해 본다면, 유가 사상 에서 파악하는 좋은 죽음과의 부합점을 찾을 수 있다. 이는 군자의 죽음을 끝맺음의 ‘종 (終)’이라 지칭하는 점에서 드러난다. 이렇게 지칭하는 이유는 유가 사상이 죽음을 삶의 끝 맺음과 완성으로 간주하기 때문이다. 하지만, 주목해야 할 부분은 이러한 끝맺음이 단순한 육체적 생명의 시간적인 끝맺음을 가리키는 것이 아니라, 정신적 삶의 가치가 완성됨을 지 시한다는 점에 있다. 다시 말하면, ‘인(仁)’으로 상징되는 인간다움의 완성, ‘성인(成仁)’을 의미한다. 이를 일종의 사명처럼 여겨 완수하고자 노력한 이후에 맞이하는 죽음이 바로 ‘종 (終)’이라 지칭할 수 있으며, 바로 이러한 관점에서 삶의 참된 끝맺음이라 해석할 수 있는 ‘웰엔딩’과의 접목 지점을 찾을 수 있다. One of the interesting subjects in modern times is to improve the quality of death. The emergence of cultural movements, called 'well-dying' or 'well-ending' is the social phenomenon to reflect this interest in the quality of death as well as life and involve the question of how to prepare my death. It is true that these attractive slogans are not carried on with theoretical contents enough to motivate the action solidly, comparing to their intentions. The viewpoint of death in Confucius thoughts could provide a way to fulfill these movements. Focused specifically on the word of 'well-ending' with close understanding of it, it can be found that the good one among death evaluated by Confucius thoughts possibly correspond to the meaning of 'well-ending'. This aspect can be revealed in the explanation that the death of man with virtue should be called 'the ending'. This is because the death is usually regarded as the ending, or completion of life. However, there is an noticeable opinion that should not be ignored. The ending in the Confucius' viewpoint of death does not indicate the end of physical and temporal meaning, but mean the accomplishment of virtuous value in spiritual life. To be more specific, this is the accomplishment of 'Humane love(仁)', representing the concept of true humanity in Confucius thoughts. If someone would take it as the mission and put his continuous effort on this mission to be complete, he could face on the death that can be called 'the ending'. Therefore, the meaning of 'well-ending' can meat the corresponding aspects to it.

Medical Costs and Healthcare Utilization among Cancer Decedents in the Last Year of Life in 2009

황인욱,신동욱,강경희,양형국,김소영,박종혁 대한암학회 2016 Cancer Research and Treatment Vol.48 No.1

Purpose The purpose of this study was to evaluate the cancer care cost during the last year of life of patients in Korea. Materials and Methods We studied the breakdown of spending on the components of cancer care. Cancer dece- dents in 2009 were identified from the Korean Central Cancer Registry and linked with the Korean National Health Insurance Claims Database. The final number of patients included in the study was 70,558. Results In 2009, the average cancer care cost during the last year of life was US $15,720. Patients under age 20 spent US $53,890 while those 70 or over spent US $11,801. Those with leukemia incurred the highest costs (US $43,219) while bladder cancer patients spent the least (US $13,155). General costs, drugs other than analgesics, and test fees were relatively high (29.7%, 23.8%, and 20.7% of total medical costs, respectively). Analgesic drugs, reha- bilitation, and psychotherapy were still relatively low (4.3%, 0.7%, and 0.1%, respectively). Among the results of multiple regression analysis, few were notable. Age was found to be negatively related to cancer care costs while income level was positively associated. Those classified under distant Surveillance, Epidemiology, and End Results stages of cancer and higher comorbidity level also incurred higher cancer care costs. Conclusion Average cancer care costs varied significantly by patient characteristics. However, the study results suggest an underutilization of support services likely due to lack of alternative accommodations for terminal cancer patients. Further examination of utilization patterns of healthcare resources will help provide tailored evidence for policymakers in efforts to reduce the burdens of cancer care.

Association of mitochondrial haplogroup F with physical performance in Korean population

황인욱,김기철,최은지,진한준 한국유전체학회 2019 Genomics & informatics Vol.17 No.1

Athletic performance is a complex multifactorial trait involving genetic and environmental factors. The heritability of an athlete status was reported to be about 70% in a twin study, and at least 155 genetic markers are known to be related with athlete status. Mitochondrial DNA (mtDNA) encodes essential proteins for oxidative phosphorylation, which is related to aerobic capacity. Thus, mtDNA is a candidate marker for determining physical performance. Recent studies have suggested that polymorphisms of mtDNA are associated with athlete status and/or physical performance in various populations. Therefore, we analyzed mtDNA haplogroups to assess their association with the physical performance of Korean population. The 20 mtDNA haplogroups were determined using the SNaPshot assay. Our result showed a significant association of the haplogroup F with athlete status (odds ratio, 3.04; 95% confidence interval, 1.094 to 8.464; p = 0.012). Athletes with haplogroup F (60.64 ± 3.04) also demonstrated a higher Sargent jump than athletes with other haplogroups (54.28 ± 1.23) (p = 0.041). Thus, our data imply that haplogroup F may play a crucial role in the physical performance of Korean athletes. Functional studies with larger sample sizes are necessary to further substantiate these findings.
