Vinca alkaloids from plant Vinca minor have been investigated for their effects of tyrosinase inhibition, stimulation of ROS generation and increasement of cell migration activity. The methanolic crude extract and the water-soluble fraction exhibited IC50 value of 3.1 mg/mL and 2.1 mg/mL. Vinca minor extract treatment significantly increased ROS levels in HaCaT cells, in a concentration-dependent manner. Treatments of Vinca minor extract led to increase wound closure when compared with non-treatment. Low dose (0.1% or 0.3%) of extracts have not significantly affected, compared with that in controls. By contrast, 0.5% extract have dramatic effect on wound healing activity of keratinocytes. Effects of Vinca minor extract in a filter-based cell mobility assay appear similar to that of wound closure assay, which suggests that the Vinca minor extract have wound healing effects on skin.

This study aimed to reveal the designer’s creative process in the development of clothing designs. The researcher has taken roles both as a design practitioner and an observer. The full process of design development was concurrently documented while working to solve a specific problem. This included noting down the concept, keywords, and detailed scratch ideas, as well as refining the design by collecting sketches and taking photos. Integrated data from the captured design process were analyzed based on Lamb and Kallal’s apparel design framework, which included problem identification, construction of preliminary ideas, design refinement, prototype development, and evaluation. The functional, expressive, and aesthetic (FEA) criteria of the entire process were thus assessed. Additionally, five professional apparel reviewers evaluated the design project based on FEA criteria. The results showed the processes for identifying targets and intentions, extracting the main elements from sources, developing the major visual concepts, and making final adjustments. Ultimately, this study revealed how a designer manages each stage of the creative design process. Sharing such detailed observations of the design process can help refine the knowledge involved in each stage of the creative process, and provide guidance for instructors in design education.

We present analyses of 1250 variable sources identied in a 20 square degree eld toward NGC 2784 by the KMTNet Supernova Program. We categorize the variable sources into three groups based on their B-band variability. The rst group consists of 31 high variability sources with their B- band RMS variability greater than 0.3 magnitudes. The second group of medium variability contains 265 sources with RMS variability between 0.05 and 0.3 magnitudes. The remaining 951 sources belong to the third group of low variability with an RMS variability smaller than 0.05 magnitudes. Of the entire 1250 sources, 4 clearly show periods of variability greater than 100 days, while the rest have periods shorter than 51 days or no reliable periods. The majority of the sources show either rather irregular variability or short periods faster than 2 days. Most of the sources with reliable period determination between 2 and 51 days belong to the low-variability group, although a few belong to the medium-variability group. All the variable sources with periods longer than 35 days appear to be very red with B􀀀V > 1.5 and V 􀀀I > 2.1 magnitudes. We classify candidates of 51 Cepheids, 17 semi-regular variables, 3 Mira types, 2 RV(B) Tauri stars, 26 eclipsing binary systems and 1 active galactic nucleus. The majority of long-term variables in our sample belong to either Mira or semi-regular types, indicating that long-term variability may be more prominent in post-main sequence phases of late-type stars. The depth of the eclipsing dips of the 26 candidates for eclipsing binaries is equivalent to 0.61 as the average relative size of the two stars in the binary system. Our results illustrate the power of the KMTNet Supernova Program for future studies of variable objects.

Arsenic (As) is a toxic element that easily taken up by plants root. Several toxic forms of As disrupt plant metabolism by a series of cellular alterations. In this study, we applied annealing control primer (ACP)-based reverse transcriptase PCR (polymerase chain reaction) technique to identify differentially expressed genes (DEGs) in alfalfa roots in response to As stress. Two-week-old alfalfa seedlings were exposed to As treatment for 6 hours. DEGs were screened from As treated samples using the ACP-based technique. A total of six DEGs including heat shock protein, HSP 23, plastocyanin-like domain protein162, thioredoxin H-type 1 protein, protein MKS1, and NAD(P)H dehydrogenase B2 were identified in alfalfa roots under As stress. These genes have putative functions in abiotic stress homeostasis, antioxidant activity, and plant defense. These identified genes would be useful to increase As tolerance in alfalfa plants.

As the global cosmetics market becomes more competitive, cosmetics firms need to be more market-oriented. Consumers purchase cosmetics products not only based on product-related attributes (e.g., function) but also for non-product-related reasons such as novelty and a pursuit of variety. They are exposed and have access to a variety of choices imported from other countries, which further complicates decision-making. Globalization offers great opportunities for marketers as it may help expand the horizon of the market beyond the domestic boundary. Given that the market is becoming more competitive, it is imperative to understand what influences purchase decisions of global consumers. This study considers and examines extended susceptibility to global consumer culture (Extended SGCC) and its effect on affective commitment, which in turn influences behavioral commitment and loyalty. We consider four elements of extended SGCC: conformity to consumer trend, social prestige, quality perception, and corporate social responsibility. In addition to examining the structural relationships among the variables, we test whether country of origin (COO) moderates the proposed relationships. In order to test the model, we collected data from the purchasers of botanical cosmetics products that came from several different countries. A total of 798 users participated in the survey (425 users of domestic brands and 373 users of foreign brands). We performed several analyses related to the measurement model such as reliability analysis (Cronbach’s alphas), confirmatory factor analysis, and correlations analysis. Using SPSS 21.0 and AMOS 21.0, we estimated the structural model. The overall model fit indices include: χ2=1118.934 with df=239, p=0.000; GFI=0.884; AGFI=0.855; NFI=0.924; CFI=0.934; RMSEA=0.068; RMR=0.069. The study finds that all elements of SGCC, with the exception of social prestige, have a significant influence on affective commitment. Specifically, conformity to consumer trend is found to have a significant effect on affective commitment. This means that consumers who conform to the global trend tend to have a higher level of commitment. One implication is that cosmetics firms may want to communicate to the consumers that their products fit the lifestyle corresponding to the global trend. Contrary to our expectation, social prestige is not found significantly related to affective commitment. It seems that social prestige is not an important factor in choosing botanical cosmetics products. This is understandable because, unlike some prestige products that consumers wear or use to be associated with their image or perceived quality (e.g., car, handbag), consumers may not purchase botanical cosmetics products to upgrade their social status. As expected, quality perception has a significant positive effect on affective commitment. The study shows that quality perception has the most significant impact on affective commitment. Corporate social responsibility (CSR) is also found to have a significant impact on affective commitment. The finding suggests that companies should be or remain active in taking initiatives that advance social welfare. Our study shows that both affective and behavioral commitments are positively related to customer loyalty. Behavioral commitment, which consists of items representing purchase tendency, has a greater influence on loyalty than affective commitment. We anticipated that country of origin (COO) would moderate the proposed relationships. We find no significant moderating effect of COO. This can be interpreted that the structural relationships are upheld regardless of COO. It seems that global consumers evaluate foreign brands in the same manner as they do domestic brands. This suggests that cosmetics firms may want to be careful in differentiating their strategies based on countries as the return on investment may not be as handsome as they thought and global consumers may have more similarities than differences with respect to how they evaluate and purchase cosmetics products.

The cabbage whitefly Aleyrodes proletella L. (Hemiptera: Aleyrodidae) is a specialized insect that uses its mouthparts(stylets) to feed from the phloem of its host plants, which are found among the Brassicaceae and Asteraceae. Female whiteflies lay their eggs in circular patterns embedded in wax on the underside of the leaves. These were collected from the leaf of triangular lettuce, Crepidiastrum sonchifolium throughout the whole Chungnam province, 2013. We reared the cabbage whitefly on the egg-plant. The elongate-oval eggs are laid upright in a semicircle on the underside of Brassica leaves but didn’t in lab. Initially pale and translucent, the eggs become darker. Nymphs are scale-like and covered with wax; their color is white with two yellow spots on the abdomen. On the dorsal surface of the last abdomial segment is the vasiform orifice charactersitic of the group. The fourth instar is called the “pupa”. The pupa is thicker, immobile, and pale in color with red eyes. The adults are tiny, about 1.5 mm long, and moth-like. The head and thorax are dark. The abdomen is yellow and covered by a conspicuous white waxy layer. The forewings have a faint, dark bar. If disturbed, the adults fly readily. The duration of development of immature stages of Aleyrodes proletella decreased with increase in temperature, the mortality was higher below 16 ℃ and above 28 ℃.

The master plan of forest land management proposes forest watershed management that considers regional characteristics in order to overcome the problem of uniform forest land management. In order to manage the forest watersheds in Gyeonggi-do, this study classified 1,823 forest watersheds in Gyeonggi-do and attempted to understand their characteristics. It conducted a factor analysis and cluster analysis from the perspective of conservation value and development pressure using forest land indicators. In terms of conservation value, three factors were drawn: the topography factor, vegetation factor and public service factor, while in terms of development pressure, three factors were drawn: the easiness of development factor, economic benefits factor and development activity factor. Using these factors, forest watersheds were divided into three clusters in terms of conservation value while they were divided into three clusters in terms of development pressure. Using the results of the cluster analysis from a conservation-development perspective, the forest watersheds were classified into nine different types, and the characteristics were identified by each type. It is judged that the factors and clusters drawn as a result of the research accurately reflect the present conditions of Gyeonggi-do, and the nine types of forest watersheds have clear characteristics according to each type, which are judged to be utilized in forest management in the future.

Dictyophora indusiata (Vent.) Desv., “Queen of the mushroom”, is a mushroom in family Phallaceae of Basidiomycota, which is commonly used as edible and medicinal mushroom in China and Korea. This study initiated to evaluate the anti-cholinesterase, skin anti-wrinkle and melanogenesis inhibitory of 80% methanol extract from fruiting body of D.indusiata. In the anti-cholinesterase experiment, acetyl-cholinesterase and butyryl-cholinesterase inhibitory activities were performed. The extract were inhibited acetyl-cholinesterase and butyryl-cholinesterase 44.09% and 49.14% at the concentration 1 mg/mL, respectively. The skin anti-wrinkle effect of the extract were determined by measuring anti-collagenase and anti-elastase activities. While melanogenesis inhibitory activities were performed by tyrosinase, DOPA inhibitory and melanin synthesis inhibitory activities. The tyrosinase inhibitory activity of the extract were from 37.60~68.96%, while DOPA inhibitory activity were from 15.43 ~ 29.58% at the concentration ranged from 0.125~2.0 mg/mL. In addition, cellular tyrosinase activity was tested with result of the enzyme activity reduced from 99.09% to 72.91% against 25~500 μg/mL of the extract. The methanol extract of D.indusiata was inhibited melanin synthesis activity 41.86% at the concentration 500 μg/mL. The collagenase inhibitory activity of the extract from D.indusiata were 34.87%, which was comparable with the positive control, EGCG ( 45.31%). While the extract showed good inhibition of elastase enzyme (46.64%). The experiment results suggested that fruiting body of Dictyophora indusiata could be used as natural anti-cholinesterase and skin care agents.

Calocybe indica (Purkayastha, 1974), Milky mushroom, is a relatively new to the world of mushroom industry, which is belong to Lyophyllaceae of Basidiomycota, and commonly used as edible mushroom in India and Southern Asia country. This study was conducted to investigate the free radical scavenging, skin whitening and anti-collagenase activities of methanol extract from fruiting body of C.indica cultivated in Bangladesh. In addition, the polyphenol compounds of the extract were analyzed by HPLC. The mushroom extract showed good activity in lipid peroxidation which ranged from 29.35% to 55.39% at the concentration 0.125~2.0 mg/mL. The scavenging activity of the extract on 1,1-diphenyl-2-picrylhydrazy radicals were from 20.22~83.93% at the same tested concentration, which were comparable with the positive control BHT. The hydroxyl radical scavenging activity of the extract was 76.24~93.92%. The skin whitening effect of the mushroom extract was performed with UV light protecting, tyrosinase and DOPA inhibitory activities. The methanol extract absorbed UV-B wavelength with maximum level of 0.356 at 280 nm. The tyrosinase and DOPA inhibitory activities of the extract were ranged from 30.36 ~ 66.25% and 7.13 ~ 30.25% at the concentration 0.125~2.0 mg/mL, respectively. Furthermore, anti-collagenase activity were determined by measuring collagenase and elastase inhibitory activity. The collagenase and elastase inhibitory activity of the extract were 42.77% and 51.08% at the concentration 1.0 mg/mL, respectively. The experiment results suggested that fruiting body of Calocybe indica could be used as natural skin care and antioxidant agents.

Several Mites are currently the most serious threat to the world bee industry. The ectoparasitic honey bee mites was originally confined to the Asian honey bee(Apis cerana etc.). Varroa destructor and Tropilaelaps clareae has plagued European honey bees, Apis mellifera. Differences in mite tolerance are reported between two honey bee species A. mellifera and A. cerana. We were amplified antimicrobial peptide cDNA genes (Defencin, Abaecin, Royalisin, Apidaecin and Hymenoptaecin) by RT-PCR. We explored the transcriptional response to mite parasitism in A. mellifera 4th instars larvae which differ in susceptibility to V. destructor and T. clareae, comparing parasitized and non-parasitized 4th instars larvae (worker and Drone) from same hive. Differential gene expression of worker bees and Drone bees induced by mites (V. destructor and T. clareae) infection was investigated by northern blot. Mites (V. destructor and T. clareae) parasitism caused changes in the expression of genes related to sex distinction. Bees tolerant to mites (V. destructor and T. clareae) were mainly characterized by differences in the expression of genes regulating antimicrobial gene expression. It provides a first step toward better understanding molecular expression involved in this differential sex distinction host-parasite relationship. We were detected bee virus in A. mellifera, comparing parasitized and non-parasitized 4th instars larvae (worker and Drone). Therefore, this result was demonstrated that mites were another possible route of horizontal transmission, as several viruses were detected in mites and their hosts.
