This study was taken place to find out the psychological change with comparing before and after the experience of installation of indoor garden with 55 of subjects out of 62 subjects. More than 50% of subject answered that the garden management would be difficult before they experience the installation but the pressure was decreased while the interest of plants and landscape increased, however, the burden of management decreased and the interest in the kinds of plants and landscape design tended to increase after the experience of the installation. The psychological effect of indoor garden of workers was significantly increased with the question of “Indoor garden improves effect of air cleaning.” after the experience of installation and the loyalty was statistically increased with the question of “Intend to invest more fund to purchase indoor plant” (p <.05). As a result of the comparison of two psychological indicators, the recovery index of the state according to experience of indoor gardening was significantly higher after experiencing the indoor garden than before the indoor gardening experience. As the result of sensibility evaluation of pleasant, natural and calm with semantic differential method, workers feel more of them with the indoor garden. In addition, the loyalty was statistically significantly higher in the question “I would be willing to invest more in plant purchase” after experiencing the composition indoor garden (p <.05). This result is similar to the result that the resident’s recovery index, pleasantness, calm feeling, and emotional index are higher the indoor garden in public resting area with indoor garden than without indoor garden. With this study, the perception of indoor garden changed as a result of the worker’s experience of indoor gardening in the workplace and the view of the indoor garden created by the workers. As the psychological healing effect of indoor garden increased, increase in the cost investment for the emotional health promotion of the workers is expected to have a positive effect on the increase of the indoor garden.

Background : Cordyceps militaris is a non-toxic, medicinal mushroom, which is known to possess anti-inflammatory and immunomodulating activities. And also, Glycyrrhiza uralensis is widely used as a crude drug in oriental medicine. However, the effects and mechanism of action of C. militaris and G. uralensis on Herpes simplex virsu (HSV), which is a serious skin disease. This study aimed to evaluate the effect of C. militaris and G. uralensis on Herpes simplex virus. Methods and Results : The results showed that the extracts and major compounds C. militaris and G. uralensis increased the TNF-α product on RAW 264.7. And also, these extracts and major compounds inhibited TNF-α product in RAW 264.7 induced by LPS. Querceitn, which was identified from G. uralensis, was showed Anti-virrus effect of Herpes simplex virus (HSV). Conclusion : Taken together, these results indicate that the anti-stomach cancer effect of C. militaris and G. uralensis in xenograft model implantated Epstein-Barr virus positive-stomach cancer cell line.

Background : Undulatum Rhubarb, commonly produced in domestic, is rhizome of Rheum undulatum L. that belongs to the family Polygonaceae. It also can be used as a substitute of R. palmatum L., R. tanguticum Maximowicz ex Balf., and R. officinale Baillon which completely depend on import system. However, there should be clear clarification among Undulatum Rhubarb and Rhubarb, because Undulatum Rhubarb contains rhaponticin as marker compound that is not indicated at Rhubarb. Some of the recently imported Undulatum Rhubarbs have been found to be Rhubarb. Also, it is known that only Undulatum Rhubarb is cultivated at domestic environment. But some plant origins of Rhubarb are grown in Korea, too. Further study are needed to clarify clear origin between Undulatum Rhubarb and Rhubarb. Thus, we collected some domestically cultivated samples and identified them. Methods and Reseults : Rheum undulatum L., Rhubarb, Rheum tanguticum Maximowicz ex Balf. which were cultivated in Gangwondo Agricultural Research and Extension Services in Cheorwon were collected and anayzed the DNA sequences. We also compared DNA sequences in Rhubarb collected from England and R. rhabarbarum L., R. undulatum L., and R. franzenbachii on NCBI. As a result, two kinds of rhubarb cultivated in the test plantation were identified as R. rhabarbarum and R. officinale. In addition, R. undulatum (plant origin of Undulatum Rhubarb) was identified as Rhubarb (Rheum rhabarbarum) in England with 99 - 100% identical in nuclear ITS gene region. Conclusion : R. undulatum, plant origin of Undulatum Rhubarb, is reported as synonym of R. rhabarbarum, R. franzenbachii. Rheum speices which are cultivated as tester in Gangwondo Agricultural Research and Extension Services in Cheorwon are estimated as R. undulatum and R. officinale. Therefore, not only Undulatum Rhubarb but Rhubarb could be grown in Korea.

최근까지 ChromameterⓇ CR-400, MexameterⓇ M18 그리고 육안평가는 피부색 평가를 위한 주된 평가방법으로 이용되어 왔다. 하지만 본 연구를 통해 피부색의 변화를 평가할 수 있는 객관성 있는 평가방법으로 이미지 분석을 제안하고자 한다. 본 연구에서는 세 가지의 기존 평가방법의 변수들과 이미지 분석을 통해 얻은 V (Value) 값을 이용하여 미백 인체 효능평가를 수행하고 변수들 사이의 상관성을 분석하여 이미지 분석의 신뢰성을 확보하고자 하였다. 효능 평가를 위해 과색소침착으로 고민하는 34명의 시험 대상자를 모집하였고 선정된 시험 대상자들은 8주간의 시험기간 동안 vitamin C가 함유된 5 종류의 미백 화장품을 사용하는 동시에 일주일에 1회 전기이온영동(iontophoresis) 시술을 받았다. 제품 사용 및 시술 전과 8주 후 기존 평가 변수들과 V 값 측정결과를 비교하고 각 변수들 사이의 상관성을 분석한 결과, 제품 사용 및 시술 8주 후 V 값은 ChromameterⓇ의 L* 값의 경향과 유사하게 증가하였으며, L* 값과는 양의 상관관계를 보이는 것을 확인하였다(r = 0.494, p < 0.01). 또한, MexameterⓇ의 MI 값(r = - 0.683, p < 0.01)과 육안평가 측정 값(r = - 0.549, p < 0.01)은 V 값과 음의 상관관계를 나타내었다. 따라서 이미지 분석의 V 값의 활용은 기존의 평가방법과 더불어 주관적인 육안평가의 한계를 보완할 수 있는 신뢰성 있는 미백평가 방법의 하나라고 생각된다.

UDP-glucose 4-epimerase (UGE) catalyzes the reversible conversion of UDP-glucose to UDP-galactose. To understand the biological function of UGE from Brassica rapa, the gene hereinafter referred to as was cloned and overexpressed into Japonica rice cv. Gopum. Transcriptional profiling showed that the is specific to stem of rice plant. Morphological evaluation of the overexpression lines revealed altered phenotype characters particularly in panicle length, number of productive tillers and filled spikelets which account for an increase in yield. This remarkable agronomic performance was ascribed to higher photosynthetic rate complemented with higher CO2 assimilation. Interestingly, BrUGE1 did not only improve plant fitness under optimal condition but also under water deficit stress. The enhanced drought tolerance may be due to the induction of soluble sugar which may act as osmolyte to compensate dehydration during drought stress.

Glutamine synthetase (GS) is an enzyme that plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine. Exposure of plants to cadmium (Cd) has been reported to decrease GS activity in maize, pea, bean, and rice. To better understand the function of the GS gene under Cd stress in rice, we constructed a recombinant pART vector carrying the GS gene under the control of the CaMV 35S promoter and OCS terminator and transformed using Agrobacterium tumefaciens. We then investigated GS overexpressing rice lines at the physiological and molecular levels under Cd toxicity. The GS activity along with mRNA expression were found higher in transgenic than in wild type plants. And this is validated by the low malondialdehyde contents observed 10 days after treatment. GS overexpression in rice resulted in the modulation of expression of enzymes responsible for membrane peroxidation, which may result in the sudden death of plants. Our results thus describe the features of a transgenic rice plants with enhanced tolerance to Cd toxicity.

Safflower (Carthamus tinctorius L.) is a herb primarily distributed throughout in the world. We have used the inter-simple sequence repeats (ISSR) technique to investigate the phylogenetic relationships and genetic diversity of C. tinctorius. Of all germplasms, 88.7% were polymorphic among all germplasms. Mean genetic diversity within germplasms was very low (0.048). The Turkey germplasm had the highest expected diversity (0.082) and Australia germplasm was the lowest (0.020). These values indicate that most of the genetic diversity of safflower is found among germplasms and there is a high among-germplasm differentiation. We found eight phenetic bands for determining the specific marker of germplasm with SCAR markers. The regions of the Mediterranean Sea and India may be the most probable candidates for the origin of safflower. The tree showed four major clades: (1) European germplasms, (2) Azerbaijan, Egypt, and Ethiopia, (3) Australia, and (4) America.
