Fermented halla gold kiwifruit (FHK) was prepared with Lactobacillus plantarum CK10, a bacterium derived from kimchi. We investigated the quality characteristics and antioxidative activity of madeleine added with FHK. The madeleine dough was prepared by mixing flour, sugar, baking powder, and then followed by adding salt, rum, different amount of the FHK (0, 1, and 3%) and butter. The total titratable acidity of madeleine increased significantly with the amounts of added FHK (p<0.05), while the pH value and total soluble solids showed the reverse trend. The color of madeleine became substantially redder with increasing amounts of FHK (p<0.05), and it appeared darker and less yellow at the same time. The total polyphenol contents of madeleines increased significantly with increasing amounts of FHK (p<0.05), but there was little difference in the total flavonoid content. When the antioxidant activities were measured in terms of 2,2-diphenyl-1-picrylhydrazyl (DPPH)- and 2,2’-azino-bis-3-ethylbenzothiazoline- 6-sulfonic acid-diammonium salt (ABTS)- radical scavenging, both measured activities of madeleines increased dramatically with added FHK in a dose-dependent manner. Our results suggested that the acidity, color, polyphenol content, and antioxidant activities of madeleines can be improved by adding the fermented gold kiwifruit.

Purpose - The purpose of this study is to investigate the relationship among narcissism, usage motives, usage behaviors, satisfaction with and continuance intention to use fashion social media. Research design, data, methodology – A questionnaire survey was used to collect data after conducting a pilot test. Based on the reliability test of the preliminary questionnaire used for the pilot test, the questionnaire was revised. The final questionnaires were administered to 238 fashion social media users and 216 were used for the data analysis. To assess the validity of these measures, exploratory factor analysis and the confirmatory factor analysis were performed. Structural equation modeling analysis were employed for data analysis. Results - Five factors of the usage motivation of fashion social media were extracted: information-seeking, relationshipseeking, practicality-seeking, enjoyment-seeking and self-expression motives. The statistical analysis confirmed the influence of the narcissism tendency on all of the usage motives of fashion social media, three of the fashion social media usage motives influencing information diffusion behavior, and the influence of the information diffusion behavior on users' satisfaction and continuance intention to use fashion social media. Narcissism exerted the highest influences on self-expression motive followed by information-seeking, enjoyment-seeking, relationship-seeking and practicality-seeking motives in order. Factors affecting fashion information diffusion behaviors are practicality-seeking motive, self-expression motive, and relationship-seeking motive. The greater the diffusion of information, the higher the satisfaction with using fashion social media. The consumers with higher satisfaction intended to use fashion social media and share information more frequently. Conclusions - The results indicate that narcissism is an important factor in fashion social media usage motivation. The main motives for narcissistic people to spread information is for the practical purpose at the most, and then to express their personality and style, and to build relationship with others. The satisfaction through active information sharing behaviors seems to play a key role to lead high continuance intention of fashion social media. These implies that marketing strategies to satisfy consumers’ narcissism and motives to use social media, and to stimulate the information diffusion behaviors can be used to meet their needs for higher satisfaction with fashion social media.

Pumpkin has long been used as traditional health materials in oriental medicine, pharmacy, medicine, and food industries in many countries. In this study, the water extract and two active components from tendril of young C. moschata Duch. were investigated on inflammation inhibitory activity. The water extract of young C. moschata Duch. showed high cell viability over 95% and it decreased the production of interlukin 6 (IL-6) and tumor necrosis factor (TNF-α) in the capacity of mouse bone marrow-derived macrophages (BMDM) upon lipopolysaccharide (LPS) stimulation. Also, isolated fraction (B4) suppressed the secretion of IL-6 and TNF-α. Among the domestically cultivated pumpkins, B4 fraction contained in the tendril part of them and it comprised of the order of tendril from Cucurbita pepo var. cylindrica, old of C. moschata Duch., and young of C. moschata Duch. These results suggest that water extracts of C. moschata Duch. and purified active compound, rutin, show anti-inflammation activity by suppression of the secretion of IL-6 and TNF-α. It can be applicable as pharmaceutical materials.

Hyperlipidemia is an increase in one or more of the plasma lipids, including triglycerides, cholesterol. Ginseng has been used as a valuable tonic and for the treatment of various diseases. The objective of this study was to evaluate the effects of Jinan red ginseng (JRG) water extract on the blood and serum in rabbits with hyperlipidemia induced by poloxamer 407 when supplied in drinking water. JRG treatment was performed for 20 weeks. We evaluated the effects of the JRG treatment on diabetes through hematological and biochemical analysis before and after JRG treatment were performed. Our results indicate that LDL, total cholesterol, and triglycerides were significantly decreased compared prior JRG supply. CRE, BUN, CK and UA levels indicating renal functions are significantly reduced when compared to those prior to the JRG supply. In addition, AST, ALT, ALP, and LDH were significantly reduced indicating hepatoprotective effect. Blood electrolytes deteriorated in HL rabbits were improved when JRG supplied. In conclusion, Biochemical and hematological analysis demonstrate that the JRG is effective to alleviate the hyperlipidemia signs.

Light is very important for plant growth and a major limiting factor in indoor plant cultivation, such as in balconies. This study was conducted to investigate the light intensity and lettuce (Latuca sativa L.) growth in an apartment balcony affected by the direction of balcony. Photosynthetic photon flux (PPF), air temperature, and relative humidity in the east-, south-, or west-facing balcony were measured for a year. The lettuce was grown in the east-, south-, or west-facing balcony. The time and amount of light entering into the balcony differed according to the direction of the balcony window. Whereas light entered into the east-facing balcony from sunrise to noon, it entered into the west-facing balcony afternoon before sunset. The temperature and humidity in the balcony also varied according to the direction of the balcony window. Daily Light Integral (DLI) in the south-facing balcony was 20~50% of outdoor and DLI in east- or west-facing balconies was 10~20%. Also, the environmental characteristics of the balconies were affected seasonally. In the spring (from March to May), the DLI was around 10 mol･m-2･day-1 and the average temperature was around 25°C. But the DLI was below 10 mol･m-2･day-1 and the average temperature and relative humidity were around 30°C and over 60%, respectively, in the summer (from June to August). In the balcony, the average temperature was maintained around 10°C even in winter, which is a condition of freezing outdoor. Growth of the lettuce in the south-facing balcony was better than that of the other directions. This is attributed to better environmental conditions of south-facing balcony. Therefore, considering the environmental characteristics of the balcony, selection and management of crops with relatively low light demand like leafy vegetables are required. It is also recommended to cultivate crops from autumn to spring.

Backgrounds : Pomelo (Citrus grandis Osbeck) is the kind of citrus fruit which is Dicotyledoneae belongs to Rutaceae and special product in Jeju island. According to the previous researches, coumarin, eliocitrin, naringin are identified and these kinds of constituents revealed to be effective as anticancer, antioxidant, and antidiabetic. Until recently, there are many investigations about its functional properties were reported, but investigation about biological activities depend on extraction conditions are not sufficient. Methods and Results : 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was performed by the method of Blois with minor modification. After adding DPPH radical to each sample solutions, the mixtures were incubated in 30 minutes at aphotic place. Then, the degree of scavenging activity was recorded by microplate reader at 490 nm. The scavenging activity was expressed by RC50, which is the concentration of sample solution necessitated to scavenge 50% DPPH radical against negative control. For α-glucosidase inhibitory activity, the method using p-nitrophenyl-α-D-glucopyranoside (pNPG) was applied. To each samples, α-glucosidase and pNPG were mixed and incubated, consequently, Na2CO3 was added to terminate the reaction. Finally, absorbance was read at 450 nm. The same as DPPH radical scavenging activity, the inhibition was explicitly expressed by the amount of sample solution to inhibit 50% α-glucosidase, IC50. The 80% MeOH extract demonstrated the highest radical scavenging activity with 74.32±8.45 μg/ml. α-Glucosidase inhibitory activity was carried out to evaluate the inhibitory activity of sugar digestion and absorption and 60, 80% MeOH extract exhibited 416.35±11.07 μg/ml and 336.57±2.03 μg/ml, respectively. Conclusion : The DPPH radical scavenging and α-glucosidase inhibitory activity were evaluated in this study. The highest DPPH radical scavenging activity was seen in 80% Citrus grandis Osbeck MeOH extract, following 60% MeOH extract exhibited the second highest scavenging activity. Also, 80% MeOH extract showed 336.57±2.03 μg/ml, which was the highest α-glucosidase inhibition among all extracts.

Background : Curcuma longa L., in the family Zingiberaceae, is distributed in tropical and/or sub-tropical regions mainly in India and China. This species is commonly called turmeric, powder is used as medicinal herbs and/or flavor enhancer. It has been cultivated in southern region mainly Jindo. However, it might be possible to extend cultivation regions due to rise in average temperature. In order to select superior lines based on agronomic characteristics, we analyzed multivariate and estimated selection effects from C. longa germplasm. Methods and Results : The C. longa germplasm were cultivated in an experimental field located in Eumseong, NIHHS, RDA. The harvested roots were investigated in agronomic characteristics included in yield and then considered its relationship among the 9 germplasm by multivariate analysis method. Results from principal component analysis (PCoA) showed that it represented 70.00% and 80.44% accumulated explanation from four and five principal compounds (PC). PCoA was conducted from 9 agronomic characteristics and then correlation coefficient has been showed by analysis between each main component value and agronomic characteristics. Value of the first PC was 2.25, 24.96% explanation of total dispersion, plant height, number of rootlet and weight of rootlet were correlated with a somewhat higher level as 0.41, 0.43 and 0.52. Value of the fifth PC was 0.94, 10.43% explanation of total dispersion, the number of shoots was correlated with a higher level as 0.87. Selection effects with outstanding candidate lines including higher lines were estimated at 126.13% in yield. Conclusion : These data on multivariate based on agronomic characteristics will be give us invaluable breeding information by selection of superior lines.

The purpose of this study was to develop a supplemental healthy food that can help prevent high blood pressure-related diseases caused due to the excessive consumption of sodium in salt. This was achieved by using ion-displacement techniques to produce mineral salt with lower sodium content by using fermented brown rice by-products rich in minerals. Mineral salt containing 2019.2 mg/100 g of potassium, 678.5 mg/100 g of magnesium, 48.7 mg/100 g of calcium, and 19.5 mg/100 g of sodium was obtained by fermenting brown rice by-products to create a culture medium for the mineral salt. Mineral salt containing 1769.7 mg/100 g of potassium, 573.6 mg/100 g of magnesium, 35.3 mg/100 g of calcium, and 19.5 mg/100 g of sodium was obtained by filtering and refining the by-product extract of fermented brown rice. The results showed that when the stream velocity of the instrument used for electrolysis was 200 mL/min and the current and the concentration of the reactive liquid in the purified water chamber were higher, the effect of electrolysis was greater. Ion hot water extraction of the fermented brown rice by-products improved by up to 95% and was collected as purified water within 90 min of the reaction time. Chloride ions with pH 7.4 were produced by mixing sodium hydroxide in a purified saline water chamber with electro-analyzed water. The salt produced in this study contained low sodium, 5.7~30%, as compared to 40% sodium content of the normal salt.

피부는 낮 동안 태양빛과 인공 빛에 끊임없이 노출되어 있으며, 그중 5%는 UV 영역, 50%는 가시광선, 나머지 45%는 적외선 영역으로 구성되어 있다. 이중 자외선의 피부에 대한 영향은 많은 연구가 되어 왔으나, 나머지 영역에 대한 연구는 미진한 실정이다. 이에, 가시광선에서 적외선 사이의 파장이 피부 섬유아세포에 어떤 영향을 미치는지 연구하고자 하였다. 광처리에 의한 효과는 광파장, 처리 시간, 광세기, 광조합 등 다양한 파라미 터들의 조합에 의해 그 효능이 결정되므로, 본 연구에서는 섬유아세포의 성장 및 콜라겐 합성과 관련된 기능을 촉진시킬 수 있는 광처리 조건을 찾아내고자 하였다. 가시광선과 적외선 영역 사이의 6개의 파장을 처리한 결과, 레드(630 nm)와 그린(520 nm) 파장에 의해 섬유아세포의 증식이 증가함을 확인하였다. 광처리 시간은 콜라겐 합성량 증가를 위해서는 10 min의 광처리가 30 min의 광처리 보다 적합한 조건이었다. 광세기는 0.05 ∼ 0.75 mW/cm2에서 6개의 광세기로 분할하여 실험한 결과, 레드 0.3 mW/cm2와 그린파장 0.15, 0.3 mW/cm2 세기가 type I collagen의 mRNA의 양을 증가시킬 수 있었다. 마지막으로 두 개 파장을 순차적으로 조합 처리하였을 때의 효과를 확인한 결과, 레드와 그린파장의 조합 조건은 섬유아세포의 수적증가를 목적으로 할 때 효율적인 방법이며, 콜라겐 합성에는 레드 단독처리가 보다 효과적인 방법이었다. 따라서 본 연구에서 제시하는 광처리 조건을 이용시 피부 세포의 성장이나 콜라겐 합성에 긍정적 영향을 유도할 수 있으며, 재생 및 피부 미용 등에 활용할 수 있는 가능성이 클 것으로 기대된다.

New observations for the times of minimum lights of a well-known apsidal motion star CW Cephei were made using a 0.6 m wide field telescope at Jincheon station of Chungbuk National University Observatory, Korea during the 2015 observational season. We determined new times of minimum lights from these observations and analyzed O-C diagrams together with collected times of minima to study both the apsidal motion and the Light Time Effect (LTE) suggested in the system. The new periods of the apsidal motion and the LTE were calculated as 46.6 and 39.3 years, respectively, which were similar but improved accuracy than earlier ones investigated by Han et al. (2002), Erdem et al. (2004) and Wolf et al. (2006).

Different biotic agents such as bacteria, fungi, nematode and virus interact with plants, and causes significant annual crop loss. The plants interact with these pathogen and undergo various changes at physiological, biochemical and molecular levels. The omics technique is a powerful way which provides important information related to molecular changes occurring during plant-pathogen interaction. Several studies have been conducted and revealed either up or down-regulation of many genes involved in metabolism, energy, photosynthesis, signaling, defense and ROS upon pathogen interaction. In this review, we highlight recent progress in proteomic studies of plant-pathogen interaction, which could be useful for controlling disease and development of molecular markers for early detection of different diseases.

Koji (Aspergillus oryzae) is used to ferment crude cereals of wheat to make a traditional alcoholic drink called Makkolli and industrial materials. It’s quality varies depending on the wheat quality. Four domestic wheat varieties (Kosomil, Jokyungmil, Geumgangmil, Baegjungmil) were characterized. They were found similar in pH (6.02 to 6.08) and total acid (0.105 to 0.120%) contents. However, amino acid content of Gemgangmil was the highest (4.46%) and that of Baegjungmil was the lowest (3.72%). The total bacillus number was highest in Kosomil (333×103CFU/ml) and lowest in Gemgangmil (60×103CFU/ml). On the other hand, the fungus number was 47×105CFU/ml in Gemgangmil and the other varieties had similar quantity. The content of Alpha-amlyase was the highest (500.01unit/g) in Kosomil followed by Jokyungmil and Gemgangmil, and the lowest was in Baegjungmil (353.32unit/g). The content of Glucoamlyase was the highest in Geumgangmil (5105.0unit/g) followed by Jokyungmil and Kosomil, and the lowest was in Baegjungmil (3880.0unit/g). Acid protease was the highest in Kosomil (3515.15unit/g) followed by Geumgangmil and Baegjungmil, and the lowest in Jokyungmil (1280.5unit/g). From the result, Koji made from Kosomil was found to be of superior quality.

Potato glycoalkaloids(PGAs) are potentially toxic to humans at high levels and current safety regulations have recommended that PGAs content in tubers of potato cultivars should not exceed 20 mg/100g·FW. Accordingly, it is important to determine the PGAs composition and levels on potato cultivars for food safty and the breeding for new cultivars with low levels of PGAs. The main aim of this study was to evaluate α-chaconine, α-solanine and total PGAs content in the peel and cortex portions in 24 cultivars including ‘Haryoung’, ‘Goun’, ‘Hongyoung’ and ‘Jayoung’, recently released by Highland Agricultural Research Institute. The total PGAs ranged from 3.1 to 10.1 mg/100g·FW. 75-94% of total PGAs was existed in the peel part of all cultivars. We selected two cultivars, which can be eaten wth the skin on tubers, and so used for soy sauce braised potatoes and baby potatoes for the rest area. These results will provide consumers and breeders with fundamental information about the content of PGAs in Korea major cultivars.

Rice blast caused by the fungal pathogen, Magnaporthe oryzae, is a serious disease affecting yield loss and decreasing its quality in rice production. Rice breeders in Korea have developed many japonica varieties showing resistance to blast. However, the blast resistance in most japonica varieties has broken down within a few years after they were released to farmers because of the spread of new virulent races of M. oryzae. There is the most effectiveness to look for novel resistant gene(s) that can express the resistance to broad-spectrum races in diverse environmental conditions. We identified a major QTL, qLB4.1 linked tightly to RM6352 and RM3643 in 52.6 cM region on chromosome 4 related to the resistance for isolate inoculation and nursery test, and neck blast from a Korean weedy rice, Geumleungaengmi33. This QTL explained 26.1∼28.6% and 45.3∼53.1% of total phenotypic variation by the allele of GL33 for isolate inoculation and nursery test, respectively. A line SR30058(52)-1-1 (Suweon545) that containing the QTL qLB4.1 was developed from Ilpum*4/GL33 by marker-assisted backcross method. This line showed resistant reactions to blast nursery test across regions and years, and resistance to neck blast at the hot-spot field in Jecheon. Suweon545 showed also durable resistance of lower 10% of diseased leaf areas (DLAs) in sequential planting method. This line screened by graphical mapping using 136 SSR markers that evenly distributed on 12 chomosomes. Suweon545 contained GL33 alleles of donor parent in a total of 12 loci (8.8%) including QTL region on chromosome 4. In future, Suweon545 would be useful to develop the broad-spectrum resistance variety in japonica rice breeding program.

A 67-year-old man visited our hospital with anorexia and abdominal discomfort after taking herb for 3 months. Abdominal computed tomograpy showed splenomegaly. Blood test showed elevation of serum alanine aminotransferase level, thrombocytopenia, and there was no viral or autoimmune hepatitis. Liver biopsy showed comprehensive fibrotic changes and necrosis on iver parenchyma. He recovered within 1 week after stopping the herb. There was no disease recurrence for 1 year. No case of toxic hepatitis by taking Fritillaria thunbergii Miquel has been reported. Thus, this case proved for the first time that Fritillaria thunbergii Miquel could cause drug induced liver injury.

Transposon elements are widely distributed in the plant genomes. Maize genome consists of various transposable elements that constitute as much as 80% of the genome. Transposon display (TD) is a modified from AFLP, and can be used to generate and display hundreds of genomic fragments affixed to transposons, consequently tagging transposons. We developed maize specific transposon insertion- sequence characterized amplified regions (Ti-SCAR) using Isaac and CACTA transposons. Currently, we have developed 58 dominant Ti-SCAR markers. Validation of the Ti-SCARs is being carried out using a various maize germplasm. Since AFLP is tedious and unsuitable for large scale application in MAS, the Ti-SCAR markers displayed simple binary presence or absence pattern. Thus, the Ti-SCARs can provide a fast, cheap and reliable PCR based assay. A pipeline in developing the Ti-SCAR will be presented in the poster.

xBrassicoraphanus, a new synthetic intergeneric hybrid between Brassica rapa L. ssp. pekinensis and Raphanus sativus L., also locally known as ‘Baemoochae’, is an interesting subject for studying polyploidy and genome plasticity in the family Brassicaceae, but very few genomic and cytogenetic information. Here, we analysed the chromosome complements and pairing of the most fertile lines, BB1 and BB5, using dual-color fluorescence in situ hybridization (FISH) and genomic in situ hybridization (GISH) to check their chromosomal segregation stability. The somatic chromosome complement of B. rapa was confirmed to be 2n=20 (2.8~4.8μm), of R.sativus, 2n=18 (2.0~3.3μm), and of xBrassicoraphanus, 2n=38 (2.2~5.0μm). There were eight, eight, and seventeen metacentric pairs and two, one, and two submetacentric pairs in B. rapa, R. sativus, and xBrassicoraphanus, respectively. Additionally, three, two, and five pairs of 5S rDNA and five, three, and eight pairs of 45S rDNA were observed in B. rapa, R. sativus, and xBrassicoraphanus, respectively. This suggests that both B. rapa (AA) and R. sativus (RR) genomes, particularly the rDNA arrays, co-exist in xBrassicoraphanus (AARR) genome. In meiosis I, nineteen bivalents were most frequent, and GISH analysis showed ten bivalents from the A genome. This study would provide a useful information for further genomic study of xBrassicoraphanus and its improvement as a new promising breeding variety.
