본 연구는 현륭원이 여러 왕조에 걸쳐 왕릉후보로 거론된 과정을 살펴보고, 정조의 풍수 인식과 함께 실패한 재혈(裁穴)에 대해 살펴보는 것을 목적으로 한다. 현륭원의 입지를 논하는 과정에서 윤선도의 논리는 중요한 의미를 가지고 인용되고 있으며 활용되는 모습이다. 그러나 현륭원의 재혈과정을 통해 정조가 이루고자 하였던 목표는 일정 정도 차질을 빚고 있는데, 여러 특징적인 모습을 확인할 수 있다. 입수룡과 좌향이 현저하게 틀어진 모습을 보이는데, ‘對珠向空’이라 해서 여의주 형상의 안산에 집착한 결과라 하지만, 입수룡과 혈처가 같은 선상에 자리하지 못하고 있다. 혈토의 출현을 중요하게 고려한 것으로 『홍재전서』에는 기록하고 있으나, 정조의 의도가 제대로 반영되지 못한 것이다. 따라서 정조의 의지에 따라 천원한 현륭원은 길지를 선정하였으나 재혈에 실패함으로써, 정조가 의도한 결과물이 완성되지 못하였다. 본인이 직접 발로 뛰고 확인한 것이 아닌, 보고에만 의지한 결과는 여러 논란의 여지를 만들었다.

With the effect that the Yipsu-ryong(入首龍) of Ju-san(主山) influenced on the layout in the view of geomantic topography(形勢), how Ahn-san(案山) affected the layout plan of the Korean academics of classical learning(書院) is researched. And how the 『Jirisinbeob(地理新法)』which had been written by Ho-sun-sin(胡舜申) was applied to the Korean academics of classical learning in the view of Li and Ch'i(理氣) is studied. In Fengshui, the method to pick out a site and to confirm the direction for building construction was divided into two, one of them was 'the geomantic topography', which included 'Ju-san following type(主山順應形)', 'Ahn-san stressing type(案山重視形)' and 'Ju-san & Ahn-san complex type(主·案山混合形)'. And the other is the 'Rule of direction(向法)'. The Korean academics of classical learning was applied by the geomantic topography of Fengshui for its layout and direction, regardless of political, regional and period factors. So when the Sa-rim(士林) needed to set direction for the Korean academics of classical learning, the ground that was appropriate to the geomantic topography of Fengshui was selected. Therefore, the Sa-rim who was abused in Neo-Confucianism had a mind of stressing geomantic topography of Fengshui and they applied it positively for building construction.

Through investigating the effects that result from the form and preference of Ahnsan (案山) and Jusan(主山) symbolizing ground in the cases of 21 of the Korean Academics for classical learning which called Seowon(書院) located in South Korea of the whole 47, to layout the Korean Academics for classical learning, what factor Sarim(士林) preferred to and how they analyzed the form of circumjacent mountains by Fengshui. While the Jusan has intrinsic attribute due to connecting with the place, Hyuljang(穴 場) , the Ahnsan has public and extrovert. It can be explained that the Sarim who established the Korean Academics for classical learning had their internal hope and external justification. To put it concretely, because of their necessity of concentrating on their study within nature and their situation as hermits apart from government through long time, they made the Korean Academics for classical learning stable and satisfactory. Therefore, they had to choose Moogocksung(武曲星) as a Jusan. And their study was essential method to take their justification. And It was attractive for them to be a public officer by their study. So they preferred to Moonpilbong(文筆峯) symbolizing their achievements on their study. So the layout of the Korean Academics for classical learning tells us that the Sarim sought internal stability and external scholarship.

Background : This study, the fraction for testing the efficacy of the Astragalus extract was concentrated active ingredient. The concentrated fraction was applied to a cosmetic material that Astragalus testing results confirmed that the improved efficacy. Methods and Results : The fractions were performed using an n-butanol solvent for increasing the efficacy of the Astragalus extract, by using the material fractions collected to compare and ultimately an increase in whitening and wrinkle efficacy. The solvent to be used in the fractions was used for the n-butanol good dissolution to the effective substance(Astragaloside, Isoflavonoid). It increased approximately 6.5 times the sample extract and the n-butanol fraction of the Astragalus as a result Astragaloside 15 ppm, 97 ppm respectively analyzed by HPLC equipment, isoflavonoid content was confirmed by an increase in the content of the fractions increased 4.5 times to 280 ppm, 1,260 ppm. Tyrosinase inhibitory effect, respectively IC50 5.70 mg/mL, IC50 1.02 mg/mL to, Collagenase producing ability is IC50 4.88 mg/mL, IC50 0.93 mg/mL with n-butanol fraction was good whitening, anti-wrinkle efficacy than the extract. Sensory evaluation was conducted in the same amount of sample, using a purified Astragalus cosmetics received high marks. Stability evaluation(MTT assay) was checked for more than 100% cell viability at the concentration 2,000 ppm. Conclusion : n-butanol fraction of Astragalus was subjected to a component analysis and In vitro test, it was confirmed an increase active ingredient content. The results of sensory evaluation and stability evaluation, it was confirmed been made to improve qualities as a cosmetic materials.

This study was performed to assess the antioxidant activities and whitening effects of Agrimonia pilosa Ledeb on melanin synthesis. The whitening effects of Agrimonia pilosa Ledeb water extracts were examined by in vitro mushroom tyrosinase assay and B16BL6 melanoma cells. We assessed inhibitory effect of Agrimonia pilosa Ledeb water extract on expression of melanogenic enzyme proteins including tyrosinase, tyrosinase-related protein 1 (TRP-1) and tyrosinase-related protein 2 (TRP-2) in B16BL6 cells. Inhibitory effect of Agrimonia pilosa Ledeb onto free radical generation was determined by measuring DPPH and hydroxyl radical scavenging activitie. Our results indicated that Agrimonia pilosa Ledeb water extract effectively inhibited free radical generation. In DPPH and hydroxy radical scavenging activity, Agrimonia pilosa Ledeb water extract had a potent anti-oxidant activity in a dose-dependent manner. They significantly inhibited tyrosinase activity in vitro and in B16BL6 melanoma cells. Also, Agrimonia pilosa Ledeb suppressed the expression of tyrosinase in B16BL6 melanoma cells. These results show that Agrimonia pilosa Ledeb inhibited melanin production on the melanogenesis. The underlying mechanism of Agrimonia pilosa Ledeb on whitening activity may be due to the inhibition of tyrosinase activity. We suggest that Agrimonia pilosa Ledeb may be useful as new natural active ingredients for antioxidant and whitening cosmetics.
