In this study, nano-micelled curcumin was produced with natural sea salt with a view to comparing the in silico molecular binding affinity of pure curcumin compound to the active site of transthyretin. Using an optical light microscope and an electron microscope, it was found that the structure of the surface and the cross-section of nano-micelled curcumin was significantly different from natural sea salt. In particular, the crystal structure and nano-components in the nano-micelled curcumin were united, and the layer was more strongly stabilized than untreated salts. In the virtual 3D structure, in silico molecular docking study, the ligand binding affinity of nano-micelled curcumin to the transthyretin active site was found to be higher than that of pure curcumin. In addition, a nano-micelled curcumin formula interacted with more amino acid residues of transthyretin domains. The pharmacophore feature of the nano-micelled curcumin also showed more condensed and constrained features than normal curcumin. These results suggest that nano-micelled curcumin may effectively bind to and stabilize transthyretin, thereby regulating transthyretin-related physiological diseases. Collectively, the nano-micelled curcumin process suggests that normal curcumin can be modified more efficiently into the novel bio-functional chemical formula to stabilize the transthyretin structure. Therefore, the nano-micelled curcumin process can be applied to the field of the regulation of Alzheimer's disease.

With the enhancements in existing major industries, cloud computing-based converging services have been created, as well as value-added industries. A variety of converging services are now provided, from personalized services up to industrial services. In Korea, they have become the driving force behind existing industries throughout the whole economy, but mainly in finance, mobile systems, social computing, and home services, based on cloud services. However, not only denial of service (DOS) and distributed DOS (DDOS) attacks have occurred, but also attack techniques targeting core data in storage servers. Even security threats that are hardly detected, such as multiple attacks on a certain target, APT, and backdoor penetration have also occurred. To supplement defenses against these, in this article, a protocol for authority management is designed to provide users with safe storage services. This protocol was studied in cases of integration between a cloud environment and big data-based technology, security threats, and their requirements. Also studied were amalgamation examples and their requirements in technology-based cloud environments and big data. With the protocol suggested, based on this, security was analyzed for attack techniques that occur in the existing cloud environment, as well as big data-based techniques, in order to find improvements in session key development of approximately 55%.

The purpose of this study was to analyze how consumers make links between convenience meat products and self-relevant consequences and value. Surveys on convenience meat product consumption patterns and hard laddering based on means-end chain theory were conducted from April 21 to April 25, 2014 and targeted 200 consumers in the US. The most preferred cooking method of convenience meat product was roast (25.9%) and the most common information medium was suggestions by friends and parents (37.1%). The main as well as desired places of purchasing were both the supermarket (33.6% and 27.3%, respectively). The most preferred promotion method was free sample events (38.5%). From analyzing means-end chains of convenience meat products, the most dominant value chain was 'taste (A)'-'good taste (C)'-'feel good (V)'. These results show that consumption of convenience meat products will increase when consumer expectations of taste and satisfaction are met. Further, results of the value measurement provide information on consumer satisfaction and needs and can be applied to set marketing strategies for Korean style convenience meat products.

In sensor networks, because sensors are deployed in an unprotected environment, they are prone to be targets of compromise attack, If the number of compromised nodes increases considerably, the key management in the network is paralyzed. In particular, compromise of Cluster Heads (CHs) in clustered sensor networks is much more threatening than that of normalsensors. Recently, rekeying schemes which update the exposed keys using the keys unknown to the compromised nodes are emerging. However, they cause some security and efficiency problems such as single group key employment in a cluster, passive eviction of compromised nodes, and excessive communication and computation overhead. In this paper, we present a proactive rekeying scheme using renewals of duster organization for clustered sensor networks. In the proposed scheme, each sensor establishes individual keys with neighbors at network boot-up time, and these keys are employed for later transmissions between sensors and their CH. By the periodic cluster reorganization, the compromised nodes are expelled from network and the individual keys employed in a cluster are changed continuously. Besides, newly elected CHs securely agree a key with sink by informing their members to sink, without exchangingany keying materials. The simulation results shows that the proposed scheme remarkably improves the confidentiality and integrity of data in spite of the increase of compromised nodes. Also, they show that the proposed scheme exploits the precious energy resource more efficiently than SHELL.

Indium tin oxide (ITO) thin films (170 nm) were grown by DC magnetron sputtering deposition on Coming glass substrates without a post annealing. The electrical transport and optical properties of the films have been investigated as a function of deposition temperature $T_{s}$ (10$0^{\circ}C$$\leq$ $T_{s}$$\leq$35$0^{\circ}C$) and oxygen partial pressure $P_{o_{2}}$, (0 $P_{o_{2}}$ $\leq$ 10$^{-5}$ torr). Films were deposited from a high density (99% of theoretical density) ITO target (I $n_2$ $O_3$: Sn $O_2$= 90 wt% : 10 wt%) made of ITO nano powders. With an increase of $T_{s}$ the electrical resistivity p of ITO thin films was found to decrease, but the mobility $\mu$$_{H}$ was found to increase. The carrier density nu shows the maximum value of 6.6$\times$10$^{20}$ /㎤ at $T_{s}$ = 30$0^{\circ}C$. At fixed Is, with an increase of the oxygen partial pressure, $n_{H}$ and $\mu$$_{H}$ were found to decrease, but p was found to increase. The minimum resistivity and maximum mobility values of the ITO films were found to be 0.3 mΩ.cm and 39.3 $\textrm{cm}^2$/V.s, respectively. The visible transmittance of the ITO films was above 80%.. 80%..

Acne vulgaris is a chronic inflammatory skin disease related to pilosebaceous unit. In acne lesions, hyperseborrhea, dysseborrhea, inflammatory event, and an imbalance in skin microflora, particularly an increase in Cutibacterium acnes (C. acnes) colonization comparing to other bacteria, have been observed. The objective of this study was to evaluate anti-acne effects of Artemisia annua extract (AAE) on antibacterial activity related to preservation of the balance in skin microbiome, inhibition of inflammation, and reduction of excessive sebum production. When C. acnes and Staphylococcus epidermidis (S. epidermidis) were co-cultured in the presence of AAE, the reduction of C. acnes growth by AAE was greater than that of S. epidermidis. In addition, when C. acnes was cultured in a medium containing AAE (C. acnes AAE), levels of cytokines such as interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and IL-6 and toll-like receptors-2 activity were decreased in comparison with C. acnes cultured in a medium without AAE (C. acnes CM). Moreover, AAE significantly inhibited excessive sebum production induced by palmitic acid. These results suggest that AAE, as a natural extract with various targets, can inhibit selective growth of C. acnes and inflammatory reactions derived from C. acnes, which are the main causes of acne, and consequently can be used as a substance to alleviate acne by reducing excessive sebum formation.

Glasswort has attracted an attention because of its interesting physiological actions. In this study, the effects of glasswort on inflammatory events including nitric oxide (NO) synthesis and arachidonic acid metabolism in cultured RAW264.7 macrophages were investigated. A series of solvent fractions, including fractions of hexane (Fr.H), ethyl ether (Fr.E), ethyl acetate, butanol, and water, were prepared from a 70% methanol extract of glasswort. Among the fractions, Fr.E showed the strongest inhibition of NO synthesis and inducible NO synthase (iNOS) expression in lipopolysaccharide (LPS)-stimulated macrophages. At a concentration of $80{\mu}g/mL$, Fr.E decreased the NO and iNOS levels by 73 and 77%, respectively, after 24 h. Fr.E showed the most potent inhibitory effects on the expressions of cytosolic phospholipase $A_2$ and cyclooxygenase-2 with $IC_{50}$ values of 33.4 and $27.9{\mu}g/mL$, respectively. Fr.H and Fr.E also significantly inhibited 5-lipoxygenase expression in LPS-stimulated macrophages. These results suggest that the hydrophobic fractions of glasswort possess anti-inflammatory activities through modulating the arachidonic acid metabolism and NO synthesis.

In modern society, the paradigm of terrorism is shifting to the form of soft targets focusing on an unspecified number of people, which is different from previous terrorist tendencies, and frequent attacks using chemicals. Therefore, this study analyzed the evacuation environment and characteristics, manual analysis of a terror response manual, and the domestic chemical management status of multi-use facilities, and proposed the following management measures for chemical terror prevention in multi-use facilities. First, a multi-use facility guideline for prompt onsite response is proposed. Second, an improvement plan is suggested through the analysis of the manual for counter terrorism. Third, integrated management is proposed through the selection of chemicals available for terrorism. Through this, it is expected that an additional improvement plan will be prepared for countermeasures against chemical terrorism in multi-use facilities. In the future, it will be necessary to analyze the problems through cases of foreign countries and take customized countermeasures.

In this study, in order to analyze the effect of the consumption value of goods on the purchase intention of corporate brand products, the model was tested using SPSS 21.0 and Smart PLS 3.0 by receiving questionnaires from 457 men and women who have purchased goods. After examining the consumption values of goods, such as limited, functional, aesthetic, hedonistic, innovative, and social ego values, and product satisfaction, the effect on purchase intention of corporate brand products was analyzed. All were found to be significant except for innovative value, and product satisfaction had a significant effect on brand attachment and purchase intention of corporate brand products. We have recently redefine goods according to the trend of the times, and put an academic significance on the first classification of goods into four categories: human brand goods, brand goods, tourism goods, and character goods. It was confirmed that there was a partial difference in consumption value and satisfaction according to the type of goods. Through research, it is intended to broaden the understanding of goods and suggest the possibility of effective and useful marketing by suggesting planning and development directions according to the target.
