고려시대 정부조직에 관한 고찰

유석영 한국행정사학회 2000 韓國行政史學誌 Vol.9 No.1

高麗王朝의 行政組織을 中央과 地方으로 나누어 그 주요 행정조직을 요약하면, 먼저 중앙행정조직은 건국이후 泰封의 9관등을 주축으로 하고 신라의 제도를 참작한 독자적인 官階를 제정하였고 그 뒤에 왕권이 확립된 成宗 · 文宗 때에 이르러서는 唐 ·宋의 제도를 도입하여 관제를 완비하였고, 몽고 지배를 받은 충렬왕 이후의 관제는 많은 변혁이 있었다. 다음 地方行政組織에는 文官制度面에서 12牧 (뒤에 8牧) · 3京 · 5都護府 · 5道 · 兩界 · 肅畿 등의 제도로서 변천되어 지방행정을 수행하였다. 武官制度面에서 地方軍制를 두었는데, 지방군은 947년(靖宗 2)에 조직된 光軍으로 시작되어 뒤에 그것을 개편한 것이 州縣軍이었다. 州縣軍 중에서 兩界의 각 鑛에 배치된 군사는 항상 유사시에 대비할 수 있도록 상비군의 태세를 갖추고 있었다. 高麗王朝의 行政組織을 고찰한 것은 이것으로 시작된 것이며, 앞으로 연구할 가치가 있고, 연구해 나아갈 것을 생각하며 韓國行敵史 연구에 일조가 되고자 한다.

Korean red ginseng (KRG), a highly valuable medicinal herb in oriental societies, has biological activity similar to that of Panax ginseng. Recently, it has been discovered that the biological activities of red ginseng can vary according to heating and steaming processes under different conditions that change the principal components of KRG and result in changes in biological activity. This study evaluated and compared the effects of high temperature- and high pressuretreated red ginseng (HRG) and commercial red ginseng (RG) on β-oxidation in C2C12 myotubes. HRG enhanced the phosphorylation levels of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC), but RG did not affect the phosphorylation of AMPK in C2C12 myotubes. HRG also promoted the nuclear translocation of forkhead box protein O1 (FoxO1), and the translocation exerted an increase in the protein expression of adipose triglyceride lipase (ATGL). As a consequence, HRG increased the mRNA expression level of carnitine palmitoyltransferase 1 (CPT-1) compared to the control. Taken together, our results indicated that HRG promotes the lipolysis of triglycerides and mitochondrial b-oxidation of fatty acids in C2C12 myotubes, suggesting that alterations to the principal components by high temperature and pressure may positively influence the nutraceutical functions of HRG.

본 연구에서는 오가피순 추출물의 항산화 효과를 평가하였다. 오가피순 추출물의 총 페놀 함량과 플라보노이드 함량은 각각 $116.33{\pm}6.09mg\;GAE/g$, $65.07{\pm}4.10mg\;RE/g$으로 나타났다. 오가피순 추출물의 항산화능은 다양한 항산화 모델(DPPH, FRAP, Reducing power, ABTS, ORAC assay)을 이용하여 평가하였다. ORAC assay를 제외한 위의 항산화 모델에서는 0.1, 0.5 및 $1.0mg/m{\ell}$의 농도로 측정한 결과, DPPH 라디칼 소거능은 오가피순 추출물의 농도가 증가함에 따라 $23.3{\pm}0.8$, $28.8{\pm}1.3$ 및 $33.7{\pm}3.7%$로 평가되었고, ABTS 경우에는 6.42, 12.47 및 16.69%로 측정되었다. 또한, FRAP 활성은 0.081, 0.160 및 0.259로, Reducing power는 0.034, 0.097 및 0.180으로 나타나 추출물의 농도가 증가함에 따라 항산화활성도 증가하였다. 한편 $0.1mg/m{\ell}$에서의 ORAC value는 $103.4{\pm}3.6{\mu}M\;TE/g$으로 나타났고, 아질산염 소거능은 0.1, 0.5 및 $1.0mg/m{\ell}$의 농도에서 각각 3.6, 9.0 및 13.2%로 나타났다. 최근 건강기능 식품의 관심도가 증가하는 것을 고려해 볼 때, 오가피순 추출물은 기능성식품 또는 천연 항산화제의 소재로써의 이용 가능성을 보였다. This study was conducted to examine the antioxidative effect and nitrite scavenging ability of extract from Acanthopanax cortex shoot. The total phenolic compound and flavonoids contents of extract from Acanthopanax corex shoot were $116.33{\pm}6.09mg\;GAE/g$ and $65.07{\pm}4.10mg\;RE/g$, respectively. Antioxidative activities were measured by various in vitro models such as DPPH radical scavenging activity, FRAP, reducing power, ABTS radical scavenging activity, ORAC assay. This results showed that the extract of Acanthopanax cortex shoot was effective in scavenging radicals and protecting oxidation when assessed various in vitro systems. Similarly, the nitrite scavenging ability of extract was increased in a dose-dependent manner. Moreover, ORAC value at a concentration of $0.1mg/m{\ell}$ was $103.4{\pm}5.6{\mu}M\;TE/g$. Considering high consumer demand beneficial health effects, Acanthopanax cortex shoot can be utilized to develop functional food health-promoting and natural antioxidant agents.

麗 ·鮮王朝의 人事制度에 관한 現代的 照明

柳錫永 水原大學校 1992 論文集 Vol.10 No.-

The purpose of this dissertation is to perspective on public personnel system in the Koryo and Chosun Dynasty. 1. The similarities between the Gwageu systems of Koryo and Chosun Dynasty may be break down as follows: 1) Both Gwageu systems were not related to the school examinations. 2) Both Gwageu systems were closely related to the social class status. 3) In both systems, such principles as the equality of opportunity, equity, and strictness were regared as of great impotance. 4) The government official examination was as more important than the military examination as in China. 5) Two Gwageu systems were introduced from China. 6) Two Gwageu systems were closely related to 'Hanpumje'(the limit of qualification). 7) Two Gwageu systems were the important means of recruiting government officials. 2. The dissimilarities between the Gwageu systems of Koryo and Chosun Dynasty may be break down as follows: 1) The subjects of the examinations Kory : The main subjects of the examination were the Five Confucian Classics, poetry, and prose. Chosun : The subjects of the examination were selected from four classic literature of Ancient China and some books on Chinese classics and history. 2) In Koryo, literature, military arts, and some other miscellaneous studies were taught at Kukjagam, and such subjects as literary composition, recitation of the Conbfucian Classics(Myongkyong), miscellaneous articles were the important contents of the examination which was taken at Dongdanggamsi. On the other hand, in Chosun, the office responsible for the examination consisted of several departments. The offical examination was taken at Yejo(the ceremonies board), and the miscellaneous article examination at each related government office. And the participants in the offical and the military examination wee limited to decendants of the Yangban(the two upper classes of old Korea) and the participants in the miscellaneous article examination were limited to the technicans. 3) In Koryo, Hyangli(lower class officals in the rural community) were not aoolwed to participate in Gwageu examination, but in Chosun, they were allowed. 4) Jigongger system which only examiner had been in charge of, and Dongdanggamsi which had consisted of single test system were transformed in early days of Chosun into an official system which many examiners were in charge of, and a three-grade-test system which consisted of three step examination. 5) In Koryo, Kukjagam examination and Seungbo examination were closely related to Kukhak(one of the government school), but in Chosun, Saengwon and Jinsa examination were not related to government schools. 6) In Koryo, the military examination was taken iregularly, but in Chosun was taken regularly. 7) In Koryo, the sons of the Five Evil Conducters(the persons who killed their king, mother, grandfather, or grandmother), the five rabbles, the persons of disloyalty and filial impiety, the court musicans of Hyangbuak(one of the three parts of court music), and other low types of persons were not allowed to participate in Gwageu examination, but in Chosun, the offsprings born of concubines, and the sons of the remarried women were also not allowed to take part in the examination by the confinement law on the child born of a concubine and the discriminating treatment law on the sons of remarried women, which had not ever been Koryo or China. 8) In Koryo, pass of the Gwageu examination meant mainly that one person could become one of the government officials for the first time, but in Chosun, it meant not only a person could become a government official but also that he could rise above an official post. 9) In Koryo, noly Hyanggong-Jinsa, the students of Kukhak, or the persons in offices could take part in Gwageu examination, but in Chosun, all young students are allowed to takd. 10) In Koryo, the system of studying under the senior person in a seated group(Jwaju-Moonsaeng system) was kept strictly, but it was abolished in the early dasy of Chosun Dynasty. 11) In Koryo, the Gwageu system was put into practice in order to strengthen the sovereign power and the bureaucracy for the aristocratic class, but in Chosun, it was applied to strengthen the bureaucracy for the Yangban class. The Gwager system should not be regarded as a mere relic of the past. It is not only worth enough being reflected in the present personal administration system which is taking a serious view of the only actual result but also very helpful to enrich historical knowledge of the personal administration in the past, if we are wise enough to review the old and learn the new, to adop and reject.

This study verified the effect of the shading device having different materials on front and back sides. This shading device has high reflectivity materials on front side, so it can reflect the direct solar effectively and prevent the solar from heating up the room during summer. On the other hand, it has high absorptance materials on back side, so it can prevent diffuse solar from penetrating the room during summer. This study suggested the proper operating method of shading devices through energy simulation.
