Objective : Recently the number of health functional food (HFF) made with Traditional Korean Medicine (TKM) herbs have been increasing. However, there was a lack of the functional and safety information on HFF. Thus, this study was performed to investigate perceptions and consumptions of the HFF in Daegu area. Method : We used the data of 'Survey in Daegu' in 2010 and analyzed characteristics of perceptions and intake conditions of HFF of 1,208 participated inhabitants. Result : Among the 1,208 respondents, 30.4% were male and 63.5% were female. Most respondents (69.3%) were between 30's and 50's decade. The recognition rate of HFF made with TKM herb appeared to 86.2%. The major route of acquiring HFF information was 'mass-media' (49.8%) ; the primary reason of using HFF was 'For health promotion and anti-aging' (69.2%). On the other hand, the recognition rate of adverse effects was 53.3%. As for intake effect, 41.5% were satisfied at HFF consumption, while 56.0% did not feel special effects through the HFF consumption. In regards to purchase place, 'HFF store' was most selected by 38.0%. 69.1% of respondents selected to TKM decoction, the reason is that it made according to TKM physician's diagnosis considered their health condition. Conclusion : HFF intake was purpose to health promotion, but HFF made with TKM was consumed without any information about that. In order that HFF be used properly to promote health, the scientific and reasonable information of HFF made with TKM herb is need for consumers.

방선균에서 DNA 전사 억제인자로써 작용하여 이차대사산물의 생산뿐만 아니라 형태분화를 조절하는 $\gamma-butyrolactone$ autoregulator receptor를 암호화하는 유전자(scaR)를 clavulanic arid 생산 균주, Streptomyces clavuligerus로부터 클로닝하고 in vitro에서 ScaR의 특징을 연구하여 보고한 바 있다. 따라서 본 연구에서는 ScaR의 in vivo 기능을 분석하기위해 상동재조합방법을 이용하여 scaR이 제거된 변이주를 제작하고 야생균주와 표현형을 비교해 보았다. 그 결과, Streptomyces clavuligerus의 형태분화에서는 큰 차이를 나타내지 않았지만 clavulanic acid의 생산에 있어서는 scaR 파괴 변이주가 야생균주에 비해 생산이 증가된 경향을 보였다. 그러므로 ScaR이 S. clavuligerus의 형태분화에는 영향을 미치지 않지만 clavulanic acid 생합성에는 negative regulator로 작용한다는 것을 본 연구를 통해 명확하게 확인할 수 있었다. A $\gamma-butyrolactone$ autoregulator receptor has a common activity as DNA-binding transcriptional repressors controlling secondary metabolism and/or morphological differentiation in Streptomyces. A gene (scaR) encoding it was cloned from Streptomyces cravuligerus, a clavulanic acid producer, and was in vitro characterized in a previous report. In this study to clarify the in vivo function of ScaR, a $\gamma-butyrolactone$ autoregulator receptor of Streptomyces clavuligerus, we constructed a scaR-deleted strain by means of homologous recombination. No difference in morphology was found between the wild-type strain and the scaR-disruptant, but the scaR-disruptant showed higher clavulanic acid production. This indicates that the ScaR in S. clavuligerus acts as a negative regulator of the biosynthesis of clavulanic acid, but plays no role in morphological differentiation.

Objective : Solar ultraviolet (UV) light can cause photoaging of human skin. Many researchers have focused on effective prevention to mitigate the aging process. This study was aimed to investigate anti-wrinkle effects of pomegranate concentration solution (PCS) using photoaged hairless mouse model. Method : To clarify the protective effect of PCS against UVB-induced photo-damage, water capacity was measured with transepidermal water loss (TEWL) in SKH-1 hairless mice. In addition, image of skin replicas was analyzed. Results : Our results showed that the PCS treatment protects skin against UVB-induced photoaging, based on the parameters including moisture capacity and TEWL. According to visual assessment of skin replica, application of 1 ml/kg PCS inhibited UV-induced wrinkle formation in mice skin as compared to the vehicle-applied control mice. Conclusion : Taken together, these results indicated that PCS could improve skin wrinkle formation induced by UVB irradiation in SHK-1 hairless mice. PCS could be applied as an anti-wrinkle agent.

구양수의 <육일거사전(六一居士傳)>의 수용 양상에 대한 소고(小考)

강수진(Kang, Soo-jin) 한국고전연구학회 2017 한국고전연구 Vol.0 No.38

본고에서는 구양수의 <육일거사전(六一居士傳)>을 변용하여 창작한 집에 대한 기(記)를 대상으로 하여, 조선 후기에 자아 또는 개인을 나타내는 양상의 한 단면을 고찰하고자 하였다. 구양수의 <육일거사전>은 구양수가 말년에 관직에서 물러난 이후의 삶을 계획하며 지은 자전이다. <육일거사전>을 변용하여 집에 대한 기(記)를 쓴 경우, 자전(自傳)에 집이라는 공간성을 부여하고 그 공간에 있는 물(物)을 통해 자아 또는 개인의 정체성을 규정하였다. 본고에서는 <육일거사전>을 변용한 기를 분석하여 공간에 대한 기의 한 양상을 밝히고, 이러한 현상이 조선 후기에 나타난 이유를 살펴보았다. 구양수의 <육일거사전>을 변용하여 창작된 기는 개인과 그 소유물이 공존하는 공간을 통해 개인의 정체성을 드러냈다. 이러한 현상이 나타난 것은 조선 후기의 도시문화와 밀접한 관련이 있다. 당시 도시문화 속에서의 문인들은 글이나 그림을 통해 자신이 소장하고 있는 고동서화를 설명하거나 묘사하였는데, 이 경우 그들의 취향을 드러내는 데에 초점이 맞춰져 있다. <육일거사전>을 변용한 기는 여기에서 더 나아가 애호하는 물(物)을 통해 자아 또는 개인의 정체성을 나타내고자 하였다. 이는 조선 후기 개인을 서술하는 방식의 한 단면을 나타내고 있다는 점에서 의의가 있다고 할 수 있다. This study aimed to investigate a pattern of the self or an individual in the late Joseon Dynasty, based on Gi of a house created by transforming The Biography of the Six to One Layman by Ouyang Xiu. The Biography of the Six to One Layman is the biography that Ouyang Xiu wrote when he planned his life after his retirement from office. When the Gi of a house was created by transforming The Biography of the Six to One Layman , the space of a house was given to the biography and the identity of the self or an individual was defined through things in the space. This Gi appeared after the 18th century. This study analyzed the Gi, created by transforming The Biography of the Six to One Layman, to find out a pattern of Gi of space. By doing so, it investigated the reason why this phenomenon appeared in a specific period. The Gi created by transforming Ouyang Xiu’s The Biography of the Six to One Layman showed its identity of an individual through a space, where the individual and his possessions existed together. The reason why this phenomenon appeared in the late Jeseon Dynasty was closely related with the urban culture of that time. At that time literary men in the urban culture explained or described their antiquarian paintings and calligraphic works they had through their writings and paintings, most of which were focused on exposing their taste. However, the Gi transforming The Biography of the Six to One Layman , going further, tried to show the identity of the self or an individual through things loved by the writer. That is to say, He set a space where the possessions were put like a house or a study, and exposed the identity of an individual through Gi of the space. The Gi transforming The Biography of the Six to One Layman was to define an individual through things, in which a way of expressing an individual along with the urban culture was shown through a genre of Gi. It is significant because it shows a pattern of the way that describes an individual in the late Joseon Dynasty.

강수진(Soojin Kang),이관수(Kwan-Soo Lee),왕세명(Semyung Wang),심호경(Hokyung Shim) 대한기계학회 2007 대한기계학회 춘추학술대회 Vol.2007 No.5

In this paper, thermo-flow characteristics of an outer-rotor type of a BLDC motor are numerically analyzed using three-dimensional turbulence modeling. In an advance design of BLDC motor, cooling blades and holes are preferred for the enhanced cooling performances. Rotating the blades and holes generates axial air flow passing through stator slots, which cools down stator by forced convection. For the present study, a new design of the BLDC motor has been developed and major design parameters such as the arrangement of cooling holes, the area of cooling holes, and cooling blades and the cooling blade angle, are analyzed for the enhanced convective heat transfer rate. It is found that the convective heat transfer rate of the new BLDC motor model is increased by about 8.1%, compared to that of the reference model.
