주방세제의 진딧물 살충효과와 분국화 생육에 미치는 영향 을 알아보기 위해 실험을 수행하였다. 복숭아혹진딧물과 목화 진딧물을 대상으로 주방세제 100, 200, 400배액 단용처리와 주방세제 400배액 100mL에 소주 10mL 또는 20mL를 혼용 하여 분무 처리하였다. 그 결과 주방세제 400배 이하의 모든 농도에서 복숭아혹진딧물은 85%, 목화진딧물은 90%의 살충 률을 보였다. 주방세제와 소주 혼용처리에 의한 살충효과 상 승은 보이지 않았다. 하우스안에서 진딧물이 많이 발생한 분 국화 잎에 400배액 이하의 농도로 3일 간격으로 2회 처리함 으로써 90% 이상의 진딧물이 감소되는 효과를 얻을 수 있었 다. 또한 분국화를 재배하면서 3~4일 간격으로 5주간 지속적 으로 주방세제를 처리했을 때, 대조구에서는 90% 잎에서 진 딧물이 발생한데 비해, 모든 주방세제 단독 처리구에서는 발 생율이 15% 이하로 낮게 유지되었다. 또한 국화의 생체중, 초 장, 엽수는 주방세제 농도가 높아질수록 조금씩 낮아지는 경 향이었으나, 초폭이나 분지수에서는 차이가 없었다. 그러나 주방세제 200배 이하의 농도에서는 국화의 잎이 갈변되거나 꽃잎 끝이 백화되는 약해가 관찰되었다.

이끼의 분쇄번식 시, 가장 적합한 배양토, 광, 온도를 구명 하기 위해 날개양털이끼(Brachythecium plumosum)와 쥐꼬리이끼(Myuroclada maximowiczii)를 이용하여 실험을 수행하였다. 실험 개시 4주 후에 사진을 찍어 Photoshop에서 이끼 면적과 녹색 평균값을 구하여 이끼의 생육 정도를 나타내었다. 배양토의 경우, 두 이끼 모두 다스란 상토에서 생육이 가장 좋았고, 상토:마사토(50:50), 원예상토, 마사토:피트모스(50:50) 에서는 비슷한 수준이었다. 버미큘라이트 단용에서는 생육이 부진하였다. 광도실험에서는 날개양털이끼는 25umol･m-2･s-1 에서 100umol･m-2･s-1까지 광도가 높아질수록 생육이 조금씩 좋아지는 경향이었으나, 쥐꼬리이끼는 3개의 광환경에서 비슷한 수준이었다. 온도 실험에서는 두 이끼 모두 23℃에서 면적과 녹색값이 가장 높아 생육도 좋았다. 이러한 결과를 종합 하면, 건조한 이끼를 분쇄하여 번식할 때, 배양토로는 보습력이 좋은 다스란 상토나 원예용 상토가 무난하며, 광도는 25~100umol･m-2･s-1 범위, 온도는 20~23℃가 적당할 것으로 판단된다.

Chamaecyparis obtusa is one of the economical conifers planted in Korea due to its good quality timber and wood characteristics. Individuals of C. obtusa containing high terpenes (HT) and low terpenes (LT) were selected for by colorimetric method. The HT of C. obtusa was delayed in wilting against various abiotic stresses compared to the LT plants. The HT group exposed to UV did not significant influence the chlorophyll content, and the chlorophyll value was higher in the HT group than the LT group. Also, chilling treatment (5℃) did not significant influence on the chlorophyll content. However treatment at -4℃ showed relatively low chlorophyll content in the LT group than the HT group. Plants exposure to high temperature was not a difference between the HT and the LT group. However, treatment at 38℃ influenced the chlorophyll content that was increased exposure time-dependently. In salt treatments, chlorophyll in the HT group was lower at high concentrations (300 and 500 mM) of NaCl. However, chlorophyll content increased to slightly in treatment time-dependently, which is 6.7% to 40%. H2O2 treatment has been a negative effect on the chlorophyll content in the HT group. All concentration of H2O2 decreased the chlorophyll content of 5% to 35%. Plants containing high terpenoids were resisted against some abiotic stress such as salt and H2O2. Our results implied that terpenoids could cause various abiotic stress resistance. These results could be utilized for efficient management and biomass production during forest silvicultures.

Digital and social media has become an indispensable channel of promotion and marketing to the enterprises. For example, compared to other means of promotional channels, such as television advertising, newspapers, social network services (SNS) are more competitive, more convenient, and lower-cost. Because individuals compose or share those posts anytime, anywhere, information spreads fast and wide on social media. SNS posts can affect people's perception, thus affecting their purchase intention and behavior. A large number of researchers investigated academic issues involved SNS, such as the influence of eWOM in social media on consumers' purchase intentions (Erkan & Evans, 2016). According to Lin and Lu’s research (2011), which suggests that gender difference also exists in social media. In addition, a study identified attributes of social media messaging activities and examined the relationships among those perceived activities, value equity, relationship equity, brand equity, customer equity, and purchase intention through a structural equation model (Kim & Ko, 2012). In this study, we focus on the motivational antecedents of digital buzz on digital and social media. Among many performance metrics of digital marketing, the most important one that really matters to advertisers is click-through. Click-through is believed to reflect viewers’ interest in the product contents that are being shown on screen, and based on that assumption, it opens a new navigation tab, such as the advertiser’s web site that can provide information about products and services of an advertising company. However, there is a caveat here. Since advertisements in digital and social media are often placed on top of the contents that the viewers have already been reading, viewers can accidentally click on the internet advertisements in which they have no interests. Viewers are only annoyed by intrusive re-routing during their digital activities. Hence, it is important that the digital media marketer to be able to distinguish between the click-throughs, knowing the difference between the clicks that are genuinely reflective of a viewer’s interest, or the rest of clicks that are not. For this purpose, we propose consumer curiosity and anticipation as drivers of click-through that are meaningful to digital markers. Consumer curiosity is an important variable that results in click-through behavior, digital propagation or buzz, and further stimulates consumers' consumption activities. In recent years, there are many studies to verify this theory. Online atmospherics have an impact on customer emotions, and perceptual curiosity has a moderating effect existed in the two variables (Koo & Ju, 2010). However, the research about curiosity’s mediation effect on purchase intention aroused by SNS contents is still limited. In addition, the neural research in this field is still limited. The research seeks to understand how the SNS contents affect customer’s curiosity toward the product which the content mentioned. Furthermore, to find the relationship between curiosity and the purchase intention by using neuromarketing methodology. Our goal is to discover the neural signatures of consumers’ motivational state that leads to click-through, exploration of contents, and finally digital buzz behavior. EEG and fMRI are commonly research approaches used in the neuroscience field. EEG detect electric activities in the brain waves and fMRI measures hemodynamic events to discover individuals’ cognitive and motivational states. After content-analyzing top 10 most shared posts in the fashion brands Facebook official account which included luxury brands such as GUCCI, Luis Vuitton, and Hermès), we extract the attractive posts’ content attributes to be the level of accuracy, graphic quality, and information value. Then, we create two different simulations of social media activities that instigates viewer curiosity at differing levels. By designing an online experiment that examines how different arrays of information can create different levels viewer curiosity in user posts, and by measuring viewers’ intention to propagate the posts, we are able to discover neural signatures of digital buzz. Potential implications to digital marketing of this research in establishing meaningful performance metrics for digital marketing are discussed.

현재 농가에서 이용되고 있는 보광등과 난방등의 특성을 조사하고 하우스내 기상 환경과 절화장미의 개화와 품질에 미치는 영향을 알아보기 위해 실험을 수행하였다. 보광등으로는 LED등(light emitting diode lamp, LED), 메탈할라이드등(metal halide lamp, MH), 고압나트륨등(high pressure sodium lamp, HPS)을, 난방등으로는 나노탄소섬유 적외선등(nano-carbon fiber infrared lamp, NCFI)을 절화장미 재배상 위에 설치하였다. 그 결과 LED와 NCFI의 광도는 각각 6.8μmol·m-2·s-1과 0.4μmol·m-2·s-1으로 매우 낮은 반면, MH와 HPS는 79 ~ 100μmol·m-2·s-1 범위로 높은 편이었다. 또한 LED와 MH는 적외선역에 파장이 없어 발열량이 거의 없었으나, HPS와 NCFI는 적외선역에 파장이 많아 발열이 많은 것으로 나타났다. 동일한 공간에서 칸막이로 실험구간을 나누어 실험이 수행되었음에도 불구하고 MH, HPS, NCFI에 의해 온도는 2°C 정도 상승되는 결과를 얻었으나, 습도에서는 처리간 차이가 보이지 않았다. 광도에 상관없이 모든 전등들은 절화장미의 개화를 촉진시켜 무처리구에 비해 적게는 5 ~ 7일, 많게는 12 ~ 14일 개화가 촉진되는 것으로 나타났다. 광량이 충분한 봄철에는 전조처리에 의해 개화소요일수가 짧아지는 만큼 절화장도 대조구보다 짧아졌지만, 광량이 부족한 겨울철에는 전조처리에 의해 절화장이 길어져 품질이 향상되는 결과를 얻을 수 있었다.

The aim of this study was to investigate the effects of foot position adjuster on body alignment and weight loads in chronic stroke patients. The subjects were 15 chronic stroke patients who were admitted to KHospital in Daegu, South Korea. The study compared the body alignment and weight load changes on flat ground with the foot position adjuster using Foot scan and Dartfish video analysis software. In the results of this study, posterior superior iliac spine (PSIS) alignment decreased significantly after use of the foot position adjuster and center pressure was significantly increased after use of the foot position adjuster. This study suggests that foot position adjuster influences body alignment and weight distribution.

Chrysanthemums (Dendranthema grandiflorum ‘Iwanohakusen’) were grown in a greenhouse with complete nutrient solution system to investigate the effect of silicon (Si) supplement on salt induced deleterious effects in chrysanthemum plants. The experiment was conducted in plastic pots supplemented with a mixture of upland soil : leaf mold : river sand (3:3:4, v:v:v). Si and salinity were treated in combination with two levels of NaCl (0 and 100 mM) and two sources of silicon (K2SiO3, KSi and silicate fertilizer, SiF) at the same concentration (1.8 mM Si) by weekly-drenching for 12 weeks. Chrysanthemum plants supplemented with Si increased in fresh and dry matter enhancing water content and salinity tolerance. The plants grown under salt stress produced less fresh and dry matter than control plant. However, Si supplement to plants under salt stress ameliorated negative effects of salt stress. In soil, EC and NaCl increased by salt stress were mitigated by Si supplement. Salt stress significantly decreased the contents of K and P in leaf, but Si supplement under salt stress significantly recovered the decreased contents with enormous desorption of K and P in soil. Added Si significantly increased content of available SiO2 with its adsorption by salt stress in soil, which was directly related to Si accumulation in leaf. However, Si uptake by roots was suppressed by salt stress irrespective of Si supplement. Si supplement did not ameliorated the negative effects of salt stress on chlorophyll content and membrane integrity in leaf of chrysanthemum plant although significantly increased Si content in leaf, but reversed pest (Liriomyza trifolii) resistance to above-control level.

We have used bulked segregant analysis to screen the strain-specific DNA marker associated thermophilic strain of Pleurotus eryngii. Bulked genomic DNAs of Pleurotus eryngii were amplified by randomly amplified polymorphic DNA (RAPD) using OP-A, OP-B, OP-L, OP-P, OP-R and OP-S primers to screen the strain-specific DNA marker. A unique DNA fragment of 500 bp was amplified with OP-A11 primer from the psychrophilic strain and sequenced. A sequence characterized amplified region (SCAR) marker was designed on the basis of the determined sequence and named as OP-A11-1. The PCR analysis with the OP-A11-1 primer showed that this SCAR marker clearly distinguish the psychrophilic strains from the control strains.

Ampelopsis brevipedunculata, a porcelain berry that is a kind of Korean domestic wild berry (Viticeae), has been known to be resistant to diseases and insects. A total of 2,622 unigenes containing 912 contigs and 1,710 singletons were obtained by sequencing 5,839 expressed sequence tag (EST) clones derived from the cDNA library of wild grape, A. brevipedunculata. In the gene ontology analysis, 1,175 genes related to biological process, 1,516 genes related to molecular function, and 1,413 ones related to cell components were annotated. Among the genes showing molecular function, 17 clones were classified into defense-related genes, and 102 were known to be related with responses to stress in plants. Domains, such as leucine-rich repeat, Serine/threonine protein kinase-related, WD40 repeat, EF-hand calcium-binding, pentatricopeptide repeat, and pathogenesis-related transcriptional factor were highly expressed. Genes encoding defense related proteins, such as chitinase, catalase, protein-serine/threonine kinases, were also clustered into an abundant group in cDNAs from A. brevipedunculata. Approximately, 80 simple sequence repeats with 2~5 nucleotides were detected in the cDNAs of A. brevipedunculata. These data could provide useful information for the genetic analysis of wild grapevines and in programs for breeding grape cultivars.

Haemaphysalis longicornis (Hl) as members of the ixodid tick inhabits lots of grass thicket of field and mountain. Ticks are blood-feeding ectoparasites that can mediate a variety of diseases to human and animals, causing Lyme disease, Rocky Mountain spotted fever, and human monocytic ehrlichiosis. Particularly, ticks can trigger an inflammatory response representing symptoms about swelling and itching in human. The aim of this study is to investigate the effect of H. longicornis extract (HlE) on production of inflammatory cytokines and their mRNA in human monocytic THP-1 cells. In a time- and dose-dependent manner, human monocytic THP-1 cells was treated with HlE. Supernatants were analyzed for the production of cytokines using enzyme-linked immunosorbent assay (ELISA). mRNA level in the culture cells was measured by a reverse transcriptase-polymerase chain reaction (RT-PCR). As a result of this study, HlE significantly induced secretion of IL-6, IL-8, and MCP-1 in THP-1 cells. These results suggest that HlE increase the release of proteins and mRNAs level of inflammatory cytokines in THP-1 cells. HlE may play a role in contributing to inflammatory diseases through stimulation of immune cells. Further research of H. longicornis is needed to better understand the elucidation of the pathogenic mechanism.

Spent mushroom substrate (SMS) is a by-product remaining after a crop of mushrooms. The fresh SMS was sample within 24 hours of removal from the production facility in DOJUN farm located in Jinju. About 11 bacterial species were isolated from fresh SMS on TSA medium. Among of them, one isolate, designated YJ02, showed the antifungal activity against Aspergillus flavus and Aspergillus ochraceous producing mycotoxin on PDA medium, potentially. The strain YJ02 was produced cellulase, xylanase, mannanase as hydrolase. The strain YJ02 was identified as members of the genus Bacillus by biochemical characteristics using Bacillus ID kit and VITEK 2 system. Comparative 16S rDNA gene sequence analysis showed that strain YJ02 formed a distinct phylogenetic tree within the genus Bacillus and was most closely related to Bacillus amyloliquefaciens with 16S rDNA gene sequence similarity of 98.7%. On the basis of its physiological properties, biochemical characteristics and phylogenetic distinctiveness, strain YJ02 was classified within the genus Bacillus, for which the name Bacillus amyloliquefaciens YJ02 is proposed.

This study was conducted to evaluate the feeding value of the spent mushroom (Pleurotus eryngii) substrates (SMS) in laying hens (Hy-Line Brown). The fresh spent mushroom (Pleurotus eryngii) substrates collected from the DOJUN farm were fermented with Bacillus subtilis EJ3 for 2 weeks. A total of twenty-four laying hens were fed corn-soy based experimental diets containing 0% (control), 5% (T1), 10% (T2) and 15%(T3) fermented SMS for 7 weeks. There were no significant differences among the treatments in egg production, egg weight, egg mass, feed conversion and viability during the experimental period. Feed intake was significantly lowered in control (118.3 g) than T1 (121.9 g), T2 (120.3 g) and T3 (122.4 g). There were no significant differences among the treatments eggshell breaking strength, thickness and haugh unit, whereas the yolk color of T1, T2 and T3 were significantly heavy than T0. The palatability of boiled meat was significantly better in the T3 laying hens than in the T0 laying hens. In conclusion, fermented SMS can be used as resource of feed in laying hen feed at 5.0-15% level without effect on performance and egg qualify.

Chronic inflammatory diseases such as Crohn′s disease and ulcerative colitis are associated with increased risk of colon adenocarcinoma. Apoptic induction of colon cancer cells by cytokines and death receptors is an important anti-cancer therapy. We observed that co-administration of TNFα and IFNγ in human colon cancer cell line, HCT116, resulted in cell death and expression of IL-32. Cleavage forms of caspase-3, caspase-9, and PARP were increased in TNFα / IFNγ-treated HCT116. mRNA expression of death receptors, including TNFR1 and Fas were not changed and NO generation was not induced by combination of TNFα and IFNγ. However, mRNA expression of IL-32α, β, and γ was increased in TNFα / IFNγ-treated HCT116. To determine the effect of IL-32 in HCT116 cell apoptosis by TNFα / IFNγ stimulation, IL-32 siRNA-transfected HCT116 cells were cultured with TNFα / IFNγ and cell proliferation was measured. IL-32 siRNA induced slight recovery of cell viability of TNFα / IFNγ-stimulated HCT116. These results suggest that IL-32 is not directly related to apoptosis of HCT116 by TNFα / IFNγ stimulation. However, IL-32 expression by TNFα or TNFα / IFNγ in a colon cancer cell line is very interesting because of the unknown effect of IL-32 in colon cancer. Our study will contribute to development of studies for IL-32 function in human colon cancer and anti-cancer therapies using cytokines.
