Helicobacter pylori are known as a causative agent of gastritis, gastric duodenum and peptic ulcer, and gastric cancer, and multiple drug use is associated with various side effects in patients. The discovery of antibacterial substances against H. pylori from Korean resource plants is an important substitute for antibiotics. 52 species of Korean resource plants were collected and extracted with 50% ethanol, and antibacterial activity against H. pylori was measured using the disk diffusion method. The toxicity of plant extracts to human gastric adenocarcinoma(AGS) cells was measured by MTT assay, and the level of IL-8 secreted when gastric epithelial cells were inoculated with H. pylori was measured. As a result of measuring the antibacterial activity of H. pylori, antibacterial activity was confirmed in 38 plant extracts. The plant species with the strongest antibacterial activity were Chrysanthemum indicum, Rheum rhabarbarum, Patrinia scabiosaefolia and Petasites japonicus. C. indicum was not cytotoxic to H. pyroli-infected AGS cells and showed anti-inflammatory effects. This study's results can be used to develop healthy, functional foods and medical materials.

The chemical composition of 86 species of native plants in Korea, including plants to be afforestation, was analyzed. The chemical composition of the species analyzed was different. The species with the highest extractable content was Viburnum dilatatum (3.91%), and the species with the lowest extractable content was Ligustrum lucidum (0.11%). The lignin content ranged from 12 to 39%, with an average of 25%. The species with the highest lignin content was Chaenomeles lagenaria (39.37%). Hemicellulose content ranged from 18 to 52%, with the highest species being Thuja occidentalis (51.22%) and Eucommia ulmoides (48.84%). Cellulose content ranged from 25 to 58%, and the species with the highest content were Prunus serrulata (57.67%), Diospyros kaki (57.14%), Aesculus turbinata (53.29%), Albizia julibrissin (53.02%), and Zelkova serrata (52.29%). The chemical composition was different for each use taxon of 86 plant species. The lignin content was the highest in the fruit group and the lowest in the group other than recommended species for afforestation. Cellulose content was highest in non-reforestation-recommended tree species and lowest in fruit trees. In classification according to tree height, lignin content was higher in shrubs than in tall trees, and cellulose content was highest in tall trees. Between deciduous and evergreen trees, the lignin content was high in deciduous trees (26.46%), and the cellulose content was also high in deciduous trees (44.01%). As a result of analyzing the correlation between each compound, there was a difference. There tended to be a positive correlation between extractives and lignin content. There was a negative correlation between extractives and holocellulose content, hemicellulose and cellulose. The higher extract content affected the cellulose content much more than hemicellulose. Also, the higher the lignin content, the lower the cellulose content. The species with low lignin content and high cellulose content were Diospyros kaki and Prunus serrulata var. spontanea. This result is expected to be primary data for bioenergy, pulp industry and bioindustry.

Background: The grading of Hanwoo (Korean native cattle) is based on four economic traits, and efforts have been continuously made to improve the genetic traits associated with these traits. There is a technology to predict the expected grade based on the 4 economic genetic SNP characteristics of Korean cattle calves using single nucleotide polymorphism (SNP) technology. Selection of highly proliferative, self-renewing, and differentiating satellite cells from cattle is a key technology in the cultured meat industry. Methods: We selected the Hanwoo with high and low-scored of genomic estimated breeding value (GEBV) by using the Hanwoo 50K SNP bead chip. We then isolated the bovine satellite cells from the chuck mass. We then conducted comparative analyses of cell proliferation, immunocytochemistry, qRT-PCR at short- and long-term culture. We also analyzed the differentiation capability at short term culture. Results: Our result showed that the proliferation was significantly high at High scored GEBV (Hs-GEBV) compared to Low scored GEBV (Ls-GEBV) at short- and long-term culture. The expression levels of Pax3 were significantly higher in Hs-GEBV bovine satellite cells at long-term culture. However, there were no significant differences in the expression levels of Pax7 between Hs- and Ls-GEBV bovine satellite cells at short- and long- term culture. The expression levels of MyoG and MyHC were significantly high at Ls-GEBV bovine satellite cells. Conclusions: Our results indicated that selection of bovine satellite cells by Hanwoo 50K SNP bead chip could be effective selection methods for massive producing of satellite cells.

To improve the quality of jujube (Zizyphus jujuba Miller var. hoonensis), which is a fruit of health functional, the effect of polyphenol preparation treatment on the fruit characteristics of two cultivars (cv. Bokjo and cv. Sangwang) of jujube was investigated. There was no difference in the height and breast diameter of jujubes tested between the polyphenol treatments and non treatment. Jujube trees treated with polyphenol preparation produced significantly more fruit than untreated in both cultivars. In cvultivar of Bokjo, the polyphenol preparation treatment increased the fruit's fresh weight and dry weight more than two times, respectively, compared to the untreated treatment. Polyphenol preparation tr eatments also changed the leaf characteristics of jujube trees. In the polyphenol-treated trees, leaf thickness tended to be thickest at the top and thinnest at the bottom. Polyphenol preparation treated jujube trees showed no difference in chlorophyll content. Moisture content was slightly higher in the untreatment than in the treatments. Visually, the polyphenol preparation treatment had a dark green color. Jujubes treated with polyphenol preparations showed differences in polyphenol content in fruits. The polyphenol content in both peel and flesh of the treatments were much higher than that of the untreatment. Reducing sugar was contained more in the peel than in the flesh and was higher in the untreatment than in the polyphenol preparation treatments. Treatment with polyphenol preparation showed differences in fruit appearance. As described above, it was found that the treatment of polyphenol preparation changed the leaves, fruit shapes and components of jujube trees. In particular, jujubes treated with polyphenol preparations are expected to contribute significantly to eco-friendly and highly functional jujube cultivation, as they appear to produce many fruits and increase the content of polyphenols and sugars.

In weapon assignment studies to defend against threats such as ballistic missiles and long range artillery, threat assessment was partially lacking in analysis of various threat attributes, and considering the threat characteristics of warheads, which are difficult to judge in the early flight stages, it is very important to apply more reliable optimal solutions than approximate solution using LP model, Meta heuristics Genetic Algorithm, Tabu search and Particle swarm optimization etc. Our studies suggest Generic Rule based threat evaluation and weapon assignment algorithm in the basis of various attributes of threats. First job of studies analyzes information on Various attributes such as the type of target, Flight trajectory and flight time, range and intercept altitude of the intercept system, etc. Second job of studies propose Rule based threat evaluation and weapon assignment algorithm were applied to obtain a more reliable solution by reflection the importance of the interception system. It analyzes ballistic missiles and long-range artillery was assigned to multiple intercept system by real time threat assessment reflecting various threat information. The results of this study are provided reliable solution for Weapon Assignment problem as well as considered to be applicable to establishing a missile and long range artillery defense system.

The purpose of this study was to assess the changes in balance and proprioception of adults with limited ankle joint dorsiflexion, after the application of talocrural joint mobilization. The subjects of this study included 23 college students in their twenties with limited ankle joint dorsiflexion. The students were randomly assigned to the ankle joint mobilization group (AJMG, n=12) and the control group (CG, n=11). After 2 weeks of intervention using grade III talocrural joint mobilization in the anterior-posterior movement, the balance and proprioception of the subjects were assessed. Static/dynamic balance capabilities and ankle proprioception were analyzed using paired t-test and independent t-test. The dynamic balance and proprioception of AJMG were significantly improved after intervention (p<.05), In the comparison between the groups after the intervention, the dynamic balance and proprioceptive sense of AJMG were significantly improved compared to the control group (p<.05). This study suggests that AJMG can help improve the dynamic balance and proprioception.

Insect peptides have been extensively studied due to beneficial effects in the treatment of infectious diseases. Melittin, a fundamental component of honeybee venom produced by European honeybee Apis mellifera, has applied to prevent various inflammatory disease and bacterial infections in human. However, the therapeutic application of melittin is limited due to its low stability, hemolytic activity and expensive manufacturing costs. In this study, we aimed to discovery unknown peptides from the Apis mellifera and evaluate its antibacterial activity against Escherichia coli KACC 10005. A total 15,853 peptide sequences were diciphered using Illumina HiSeq 2500 next-generation sequencing (NGS) platform and analyzed based on the Apis mellifera official Gene Set Version 3.2 (amel_OGSv3.2) and the Collection of Anti-Microbial Peptides (CAMPR3) database. All the peptide sequences and annotation data sets were combined and sorted by physicochemical features of antimicrobial peptides (AMPs), such as short peptide length <=50, positive charge, isoelectric point (8.0<=pl<=12), and aggregation propensity (in-vitro: <=500, in-vivo: –40<= Na4vSS <=60). Among the screened peptides, four unknown peptide candidates, named AMP1-4, were chemically synthesized and tested for antimicrobial activity in comparison with a reference peptide, melittin. Inhibition of bacterial growth was observed in the AMP4 treated group from 6 hours to 48 hours post-treatment against E. coli. These results suggest that honeybee-derived peptide sequences can be applied as natural resources to acquire novel AMPs and the peptide sequences derived parameters are enough to recognize antibacterial peptides. In addition, the selected novel peptide candidate, AMP4, has antibacterial activity.

Corporations, governments, and non-profits across the world have implemented proenvironmental campaigns to promote sustainable practices. To better understand crosscultural differences in environmental persuasion, we draw on research on self-conscious emotion (Tangney & Dearing, 2002), construal level theory (Trope & Liberman, 2010), and cultural psychology (Ratner, 2000). The current research examines how the emotions of guilt and shame cause people from Eastern and Western cultures to differently perceive green advertising messages that are framed concretely or abstractly. Two hundred fifty-five undergraduate students were randomly assigned to a 2 (emotion priming: guilt vs. shame) x 2 (construal message frame: abstract vs. concrete message) x 2 (nationality: Americans vs. Koreans) between-subjects design. The results indicate that message concreteness effect is present among guilt-primed Americans and shame-primed Koreans (culturally relevant), but absent among shame-primed Americans and guilt-primed Koreans (culturally irrelevant). Theoretical and practical implications are discussed for developing global green advertising message strategies.

The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

This study aims to identify the effects of extracorporeal shock wave therapy and stretching technique on flexibility, muscle tone and pressure pain threshold of a shortened hamstring. A total of 40 patients with hamstring shortening was randomly assigned to either the extracorporeal shock wave therapy group (n=20) or extracorporeal shock wave therapy with stretching technique group (n=20) to identify the effects of the two different forms of physical therapy intervention. All the participants underwent extracorporeal shockwave therapy twice a week for 3 weeks, and the extracorporeal shockwave therapy with stretching technique group performed stretching techniques with the same frequency for 3 weeks. To measure hamstring flexibility before and after intervention, the passive straight leg raising test was performed, and muscle tone and pressure pain threshold were assessed. The flexibility of the hamstrings significantly improved, while the pressure pain threshold increased in both groups. These findings suggest that the effective in improving hamstring flexibility, reducing muscle tone, and increasing pressure pain threshold in adults with hamstring shortening.

The recent developments of artificial intelligence (AI), such as Google AlphaGo and IBM’s Watson, defeating human experts in public game venues, have instigated much surprise and awe among us. We are now genuinely curious about the true growth potential of AI into the future. Some of us are already imagining a darkening future where all human managerial positions can be replaced by machines leaving humans in a marginalized place after the point of singularity where machine intelligence achieves intellectual superiority over us and becomes a truly autonomous being. Likewise, the potential of AI has been overestimated or underestimated; rarely has it been addressed in the open context where marketing academics serve the role of an architect of future marketing AI, to provide valuable insights. We are enlightened about a possibility that the future of and marketing can greatly benefit from advanced forms of artificial intelligence. But how and where can this new technology be integrated in the every-day lives of consumers, to optimize business functions and create much higher levels of collective value for consumers, companies, and machines altogether? In this talk, we will discuss the following three points related to the AI and its potential future in the field of marketing. First, for consumers, we will discuss how marketing AI can help consumers to make better decisions about their eating, health, and consumption to enjoy better life, do more, and be happy. Second, for business, we will discuss the roles of AI and design a collaborative work process that can employ both human ingenuity and machine accuracy. Third, we suggest ethical issues related to marketing AI, delineating its boundaries and suggest governing policies to prevent potential danger spots. The purpose of talk is not to present a definitive answer, but to instigate an open discussion among the marketing academics, about the future of marketing, where AI will be an indispensable partner in the value creation process.

A newly recorded species, Nereiphylla hera Kato and Mawatari, 1999 which was originally described from northern Japan, was collected from East Sea in Korea. Our Korean materials of N. hera are distinguished from it congeners by the following characteristics that agree well with the original description of the species: the tentacular cirri are flat and spatulate with a narrow and distinct tip, reaching to segment 4-6, and boarder than their cirrophores; the parapodia possess elongated dorsal cirri. We provide a key for distinguishing the species of genus Nereiphylla from Korean waters.

A newly recorded glycerid polychaete collected from mud of the tidal flat in the southwestern coast of Korea is identified as Glycera fallax Quatrefages, 1850 based on the morphologies of papaillae and ailerons on proboscis, parapodial postsetal lobes, and branchiae. In this paper, we provide a detailed description and illustration of Korean materials of this species and a key to the species of the genus Glycera from Korean waters.

A harpacticoid species, Paramphiascella fulvofasciata Rosenfield and Coull, 1974, belonging to Miraciidae Dana, 1846 is newly reported from Korean waters. The species is mostly related with P. pacifica Vervoort, 1962, however, it is easily distinguished by the typical structure of male P2 in having 1 large spine and 2 setae on P2 enp-2. Korean materials represented some discrepancies from the original description of P. fulvofasciata in the detailed structures of mouth parts. The present study is a first record of the genus Paramphiascella Lang, 1944 from Korean waters.
