  • 본 연구는 고등어의 지질산패에 미치는 녹차 및 연잎의 항산화 효과를 알아보기 위하여 1%와 2%의 농도의 녹차 및 연잎 열수추출물에 처리하여 28일간 $4^{\circ}C$ 냉장보관하면서 염장고등어의 품질특성에 대해 알아보았다. 수분은 대조구의 경우 저장기간 동안 점점 감소하는 현상을 보였으나 처리구에서는 14일까지 감소하였으며 조단백질과 조회분은 저장기간 동안 큰 변화는 없었다. 조지방의 경우 대조구에서는 저장기간 동안 점차 증가하였으나 처리구에서는 오히려 감소하였다. pH는 저장기간이 경과함에 따라 부패가 진행되어 처리구, 대조구 모두 상승하는 경향을 보였으며 특히, 대조구의 경우 저장 7일째 6.35를 나타냄에 따라 부패가 시작되었음을 알 수 있었다. VBN은 저장초기 대조구를 포함한 모든 실험구에서 5.1~5.3 mg%로 매우 신선한 상태를 유지하였으며 저장기간 동안 처리구는 대조구보다 완만하게 증가하는 모습을 보였다. TMA-N의 경우 대조구와 비교하였을 때 1%의 농도처리 보다는 2%, 녹차 열수추출물보다는 연잎 열수추출물로 처리한 고등어에서 낮은 값을 보였다. TBA가, 과산화물가 및 산가를 측정한 결과 모두 비슷한 경향을 나타내었는데 저장기간에 따라 대조구에서는 급격히 증가하는 반면, 녹차 및 연잎 열수추출물을 농도별로 처리한 고등어에서는 증가폭이 완만하였으며 1% 농도에서 보다는 2%에서 처리한 고등어가 현저히 낮은 값을 보였다. 본 실험결과로 종합해 볼 때 염장고등어 제조시 녹차 및 연잎 열수 추출물 처리가 고등어의 지질산패 감소하는데 효과적이었으며 특히, 열수 추출물 고등어처리에 있어서 전반적으로 1%보다는 2% 농도 처리가 효과적인 것으로 판단되었다.

  • 신선편이 연근의 갈변을 저해하기 위해 감초, 황기 추출물로 블랜칭 처리하여 색도, 경도, DPPH radical 소거능, pH 및 가용성 고형분 함량을 분석하였다. 갈변의 지표인 색도 $50^{\circ}C$ 값의 결과, 감초 또는 황기 추출물을 처리한 구에서 대조구보다 높게 나타났다. 경도의 경우 모든 구에서 유의적 차이가 발견되지 않았으며, DPPH radical 소거능은 모든 구에서 저장 기간에 따라 감소하였으나 감초 추출물 처리구의 활성이 가장 높게 유지되었다. pH는 저장 기간에 따라 모든 구에서 감소하였으나 대조구가 가장 서서히 감소하였으며, 가용성 고형분 함량의 경우 저장 기간이 증가할수록 처리구의 함량은 증가하고 대조구는 그 수준을 유지하였으며 처리구 사이의 유의적 차이는 나타나지 않았다. 이러한 연구 결과를 통해 감초와 황기 열수 추출물의 블랜칭 처리가 신선편이 연근의 품질 열화에는 영향을 주지 않으면서 갈변을 효과적으로 억제함을 확인할 수 있었다.

석가탑(釋迦塔)의 경전적인 건립시점 고찰 - "견보탑품(見寶塔品)"의 내포의미를 중심으로 - (Consideration on Scriptural Foundation Viewpoint of Seokgatap - Centering on Implication of "Gyeonbotappum" -)

  • Seokgatap and Dabotap are representing the tower patterns in "Gyeonbotappum" of the Lotus Sutra. It is very peculiar, for the description on "Gyeonbotappum" is usually made in terms of 'the two Buddhas sitting side by side'. If 'the two Buddhas sitting side by side' is describing the situation in Dabotap, the double structure of Seokgatap and Dabotap can be said to symbolize the scriptural description in a different viewpoint. Its correct comprehension is pretty important in understanding Bulguksa. For this, this paper first arranged the critical minds and flows about the faith objects in Indian Buddhism. And, it was considered how these aspects were accumulated through Saddharma-pundarika sutra. Secondly, it was considered why "Gyeonbotappum" took the typical symbolism in Saddharma-pundarika sutra(Lotus Sutra). These parts should be necessarily considered in advance in that Seokgatap and Dabotap were derived from the form of "Gyeonbotappum". Based on this approach, the author checked the actual aspects of Seokgatap that the tower was built on a natural rock ground and the stones surrounding the tower are constituting the 8-directional Lotus site. With these two aspects, we could get the clue on the foundation time of Bulguksa that its founder had intended. In that Dabotap was formed on the basis of "Gyeonbotappum", the features of Dabotap is very important in comprehending its foundation viewpoint. As a result, the viewpoint of double towers in Bulguksa can be said to be the one that the world of suffering was to change to the Pure Land after Sakyamuni preached the Lotus Sutra on the top of Mt. Grdhrakuta and Prabhutaratna-tathagata proved it. This foundation viewpoint shows us clearly that 'the Lotus Buddhist Country' existed in parallel to the Avatamska Buddhist Country. It secures an appropriate meaning in that it can complement or adjust our understanding on the 'Buddhist country (Bulguk)' of Bulguksa where the Avatamska Idea is emphasized relatively highly as shown in the whole title of Bulguksa as 'Avatamska Bulguksa.'

  • The purpose of this article is making investigation of the principal composition of the twin-pagodas in Buddhist temple through ornaments of a case preserving relics of Buddha in the east and west pagodas of Gameunsa temple. This research has an important meaning in clarifying that the concept of placement two Buddhas together with lotus sutra, which was only applied to Bulkuksa temple, has been extended to Gameunsa temple. And this observation gave us a clear explanation for the principal composition at the twin-pagodas in Buddhist temple plans. The author obtained the following conclusion from this article : The cases preserving relics of the Buddha for the west and east pagodas are globally in similar form as the type of a royal palace. But the different points between eastern and western can be seen on the existence of Buddhist statues on the base floor, set-up of the gate at railings, and 4 lion statues at a coner of the base floor. In the western pagoda, there are Buddha statues above the base-floor of the cases preserving relics. These Buddha statues are composed of a boy monks and angels with playing music for the praise of the Sakyamuni Buddha lecturing the Lotus sutra at YoungChui Mountain. On the other hand, in the eastern pagoda, Buddha statues on the cases preserving relics are composed of a the Four Devas and monks as a defending God of the nation of Buddha. In the eastern pagoda, one can see something that does not exist in the western pagoda, which is a gate located in railing of a case preserving the relics. This gate described the scene of the Sakyamuni Buddha entering into the pagoda of 7 treasures. In a corner of the case preserving relics in the eastern pagoda, there is another thing which does not exist in the western pagoda. This is a sculpture of a lion which symbols the seat of Lion supporting the Buddha in the Dabotap(the pagoda of 7 treasures). When we observe the form and structure, the descriptions at the railings, the gate, the shrine, the statue of a lion, and the accessories in jewelries, at the cases preserving the relics in the eastern pagoda, one can realize that they have the same combination structures between the ones at Dabotaps in Bulguksa temple and those in China as well as in Japan, all of which represent the Gyun-Bo-Tap-Pum of Lotus Sutra. Among the distribution rules in the twin-pagodas in Buddhist temple, the application of the ideal of lotus was known to be effected only to Bulguksa temple. But from the result of the present article, it is more clearly proved by applying the Gameunsa temple that the distribution theory in the twin-pagodas in Buddhist temple was in fact based on the ideal of lotus.

  • In this study, we fabricate a superhydrophobic surface made of hierarchical nanostructures that combine wax crystalline structure with moth-eye structure using vacuum cluster system and measure their hydrophobicity and durability. Since the lotus effect was found, much work has been done on studying self-cleaning surface for decades. The surface of lotus leaf consists of multi-level layers of micro scale papillose epidermal cells and epicuticular wax crystalloids [1]. This hierarchical structure has superhydrophobic property because the sufficiently rough surface allows air pockets to form easily below the liquid, the so-called Cassie state, so that the relatively small area of water/solid interface makes the energetic cost associated with corresponding water/air interfaces smaller than the energy gained [2]. Various nanostructures have been reported for fabricating the self-cleaning surface but in general, they have the problem of low durability. More than two nanostructures on a surface can be integrated together to increase hydrophobicity and durability of the surface as in the lotus leaf [3,5]. As one of the bio-inspired nanostructures, we introduce a hierarchical nanostructure fabricated with a high vacuum cluster system. A hierarchical nanostructure is a combination of moth-eye structure with an average pitch of 300 nm and height of 700 nm, and the wax crystalline structure with an average width and height of 200 nm. The moth-eye structure is fabricated with deep reactive ion etching (DRIE) process. $SiO_2$ layer is initially deposited on a glass substrate using PECVD in the cluster system. Then, Au seed layer is deposited for a few second using DC sputtering process to provide stochastic mask for etching the underlying $SiO_2$ layer with ICP-RIE so that moth-eye structure can be fabricated. Additionally, n-hexatriacontane paraffin wax ($C_{36}H_{74}$) is deposited on the moth-eye structure in a thermal evaporator and self-recrystallized at $40^{\circ}C$ for 4h [4]. All of steps are conducted utilizing vacuum cluster system to minimize the contamination. The water contact angles are measured by tensiometer. The morphology of the surface is characterized using SEM and AFM and the reflectance is measured by spectrophotometer.

  • 스카프는 인체의 보온 역할뿐만 아니라 여성 의복의 액세서리로서 큰 역할을 해 왔다. 오늘날 액세서리에 관한 관심이 높아지면서 스카프는 의복의 보조적 역할에서 벗어나 점차적으로 패션의 전체적 분위기를 이끌어 가는 주도적인 위치로 그 비중이 확대되었다. 그러나 우리나라의 스카프 디자인은 해외 브랜드에 대한 모방의 단계를 벗어나지 못하고 있는 실정이므로 이제는 우리만의 스카프 디자인을 개발해야만 한다. 따라서 본 연구에서는 한국적이면서 현대적인 감각을 살린 스카프 디자인을 개발하기 위하여 분청사기에 표현된 연꽃문양과 전통 조각보를 디자인 개발의 소재로 선택하였다. 분청사기에 표현된 연꽃문양의 형태는 사실적인 표현보다는 그 문양을 단순하게 또는 반추상적으로 표현한 것이 많고 조각보의 기하학적인 조형미는 현대 감각에 맞는 한국적인 이미지를 잘 표현한 소재이다. 먼저 분청사기에 나타난 연꽃문양과 조각보에 대한 자료 조사를 실시하여 기초 자료로 활용하였다. 그 중에서 현대적인 이미지를 잘 나타내는 것을 선정하여 컴퓨터 디자인 프로그램을 이용, 기본 패턴 세 가지를 구성하였다. 구성된 각 패턴을 가지고 정사각형 스카프 및 장방형 스카프를 각각 재구성하여 완성하였다.

  • This study was conducted to gather basic data on the physiological activities of flower extracts from 4 cultivars of white lotus to promote the increase of public consumption. Four cultivars of white lotus: c.v. 'Garam', 'Choeue', 'Baekhwageonryeon', and 'Seungdal' were harvested on 14, August, 2007, and the physiological activities of flower extracts obtained by hot water extraction and ethanol extraction were examined. Total phenol content was highest in the 'Garam' flower hot water extracts, $144.2{\mu}g{\cdot}mL^{-1}$, and lowest in the 'Seungdal' flower ethanol extracts, $63.4{\mu}g{\cdot}mL^{-1}$. DPPH radical scavenging activity was highest at 2,000ppm flower extract of 'Garam' obtained by hot water extraction and ethanol extraction of 90.9% and 83.0%, respectively. Total flavonoid content in the flower extracts of 'Garam' obtained by hot water extraction and ethanol extraction showed the highest levels at $34.1{\mu}g{\cdot}mL^{-1}\;and\;33.9^{\mu}g{\cdot}mL^{-1}$, respectively. Nitrite scavenging activity at 1,000ppm flower extract was highest in 'Garam'. Extracts obtain by hot water and ethanol showed 91.3% and 80.4% activity, respectively. No significant difference in tyrosinase inhibition activity was observed among the cultivars or as a result of extraction method. Overall anti-microbial activity of the flower extracts was slightly higher in 'Garam' than in the other cultivars.

  • This study was conducted to evaluate the mechanical (texture and color) and sensory characteristics of mulberry leaf sulgi (MLS) and lotus leaf sulgi (LLS) that contained different ratios of ingredients. MLS and LLS with final concentrations of 0%, 1%, 3% and 5% of powdered mulberry and lotus leaf respectively, were prepared. The texture characteristics (hardness, adhesiveness, springiness, cohesiveness, gumminess, chewiness), color values (lightness, redness, yellowness), and sensory characteristics (color, flavor, moistness, taste, brittleness, chewiness and after-taste) of the different sulgis were then measured and compared. With the exception of gumminess and chewiness, the texture characteristics of 0% MLS, 1% MLS and 3% MLS were not significantly different. The sensory characteristics of 0% MLS had the highest scores, whereas those of 5% MLS were the lowest for all factors except for brittleness. However, with the exception of chewiness, the scores obtained from 0% and 1 % MLS did not differ significantly. In addition, 1% MLS and 3% MLS were not significantly different from each other. Furthermore, the texture characteristics of 0% LLS and 1 % LLS were not different significantly, although the characteristics of 1% LLS were significantly different from those of 3% and 5% LLS when springiness, cohesiveness, and chewiness were considered. Additionally, the sensory characteristics of 0% LLS and 1% LLS were not significantly different, with the exception of brittleness, and the characteristics of 1% LLS and 3% LLS were not significantly different, with the exception of taste and after-taste.
