본 연구의 결과를 중심으로 결론을 제시하면 다음과 같다. 한식을 이용한 스타 마케팅에서 배용준의 사랑을 주제로 한 퓨전화가 이영애의 대장금을 주제로 한 전통한식보다 선호도가 높은 것으로 나타났으며, 국가별 차이는 없었다. 이는 한국의 전통음식에 대한 낮은 인지도와 전통성을 현대적 관점에서 조화롭게 개발하는 것이 그만큼 한계가 있음을 의미한다. 또한 한식 퓨전화를 통한 국제표준 메뉴로서 정착시키기 위해서는 서비스의 일정한 균형과 믿음을 줄 수 있는 신뢰가 우선시됨을 알 수 있고, 이러한 요인이 뒷받침될수록 현지 국제적으로 상승 효과를 안고 성공적인 정착과 활성화에 기여할 수 있음을 시사해 주었다.

Section 39(5) of Marine Insurance Act 1906 concerns the case where with the privity of the assured, the ship is sent to sea in an unseaworthy state. The underwriters argue that the assured had"blind-eye knowledge" of the particular respect in which the ship was unseaworthy. Blind-eye knowledge requires a conscious reason for blinding the eye. There must be at least a suspicion of a truth about which one do not want to know and which one refuse to investigate. What has caused greater difficulty is the broad provision in s.17 which appears to be unlimited in its scope. The expression "utmost good faith" appears to derive from the idea of uberrimae fidei, words which indeed appear in the sidenote. The concept of uberrima fides does not appear to have derived from civil law and it has been regarded as unnecessary in civilian systems. S.17 raises many questions. But only two of them are critical to the decision of the present appeal-the fraudulent claim question and the litigation question. It is however necessary to discuss them in the context of a consideration of the problematic character of s.17. In the Star Sea Case, for the defendants to succeed in their defence under this part of the case the defendants have to show that claim was made fraudulently. They have failed to obtain a finding of fraud. It is not enough that until part of the way through the trial the owners failed to disclose to the defendants would have wished to see in order to provide them with some, albeit inadequate, evidential support for their alleged defence under s.39(5). The defence under s.17 fails. The Purpose of this work is to analyze the Star Sea Case, and to explore problems of the MIA relating to the judgement of this case.

세계는 지속가능개발에 대한 관심을 가져왔고, 지속가능의 3가지 가치(환경보전성, 경제성장성, 사회발전성)를 중요시 여겼다. Rio+20 회담은 "녹색경제"에 대해 주목하고 지속가능개발을 위한 방안을 모색하려 했지만, 결론적으로 Rio+20에서 제시한 "The Future We Want"에 대한 답을 찾지 못하여 많은 아쉬움을 가지고 있다. 또한 지속가능개발의 3가지 가치만으로는 지속적인 발전에 한계가 있다고 판단되고, "The Future We Want"에 대한 해답과 지속가능개발의 발전을 위한 방안으로써 5가지 가치 즉, 녹색별(환경보전성, 경제성장성, 사회발전성, 과학기술성, 자율자발성)을 제안한다. 그리고 4대강사업의 결과를 녹색별로 검증함으로써 녹색별 모델을 지속가능발전을 위한 새로운 패러다임으로 제시하고, 대한민국의 안녕강국을 기대한다.

Echinodermata use saponins in chemical defense against pathogens and predators. The molecular mechanisms of antimetastatic effects of brittle star saponins are still unknown. The present study examined antioxidant capacity and invasive ability in HeLa carcinoma cells exposed to brittle star crude saponins. Discolorating methods with DPPH and ABTS and expression of SOD-2 with RT-PCR were used to estimate the antioxidant activity. The anti-invasive activity of extracted saponins was examined through adhesion of HeLa cells to extracellular matrix, wound healing and evaluation of the mRNA levels of MMP-2 and MMP-9 by real time-PCR. The results showed that extracted saponins had cytotoxicity against cervical cancer cells and ABTS and DPPH scavenging properties with $IC_{50}$ values of 604.5, $1012{\mu}g/ml$, respectively. Further, we found that, in wound healing assay, brittle star saponins could prevent invasion of HeLa cells in a concentration dependent manner. Furthermore, cell adhesion assay demonstrated blockage of cell attachment to extracellular matrix with an $IC_{50}$ concentration of $16.1{\mu}g/ml$. The significant dose dependent down regulation of MMP-2 and MMP-9 in treated cells demonstrated that isolated saponins can decline tumor metastasis in vitro. The brittle star saponins remarkably prevented cervical cancer invasion and migration associated with down regulation of matrix metalloproteinase expression. Therefore, saponins could be suggested as an anti-invasive candidate against cervical cancer and an antioxidant as well.

We will present a discovery of an elliptical jellyfish galaxy in Abell 2670 (Sheen et al. 2017, ApJL, 840, L7). Our MUSE IFU spectra revealed a rotating gas disk in the center of the galaxy and long ionised gas tails emanating from the disk. Its one-sided tails and a tadpole-like morphology of star-forming blobs around the galaxy suggested that the galaxy is experiencing strong ram-pressure stripping in the cluster environment. Stellar kinematics with stellar absorption lines in the MUSE spectra demonstrated that the galaxy is an elliptical galaxy without any hint of a stellar disk. Then, the primary question would be the origin of the rich gas component in the elliptical galaxy. A plausible scenario is a wet merger with a gas-rich companion. In order to investigate star formation history of the system (the galaxy and star-forming blobs), we derived star-formation rate and metallicity from the MUSE spectra. Photometric UV-Optica-IR SED fitting was also performed using GALEX, SDSS, 2MASS and WISE data, to estimate dust and gas masses in the system. For a better understanding of star formation history and environmental effect of this galaxy, FIR/sub-mm follow-up observations are proposed.

Star forming dwarf galaxies in various environments are attractive objects for investigating the environmental effects on chemical evolution of dwarf galaxies. Using SDSS DR7 spectroscopic data and GALEX ultraviolet (UV) imaging data, we study the chemical properties of star forming dwarf galaxies in various environments of the Virgo cluster, Ursa Major group, and field. We derived gas-phase abundance, galaxy mass, and UV specific star formation rate (sSFR) of subsample, early-type (ETD) and late-type star forming dwarf (LTD) galaxies, which are divided by visually classified galaxy morphology. We found no O/H enhancement of LTDs in cluster and group environments compared to the field, implying no environmental dependence of the mass-metallicity relation for LTDs. LTDs in the Virgo cluster and Ursa Major group have similar sSFR at a given galaxy mass, but they exhibit systematically lower sSFR than those in isolated field environment. We suggest that LTDs in the Virgo cluster are an infalling population that was recently accreted from the outside of the cluster. We found that ETDs in the Virgo cluster and Ursa Major group exhibit enhanced O/H compared to those in the field. However, no distinct difference of N/O of galaxies between different environments. The chemically evolved ETDs in the Virgo cluster and Ursa Major group also show similar mass-sSFR relation, but systematically lower sSFR at a fixed galaxy mass compared to the field counterparts. We suggest that ETDs in the Virgo cluster and Ursa Major group have evolved under the similar local environments. We also discuss the evolutionary path of ETDs and LTDs with respect to the environmental effects of ram pressure stripping and galaxy interaction/merging.

Turbulence is a phenomenon which largely determines the density and velocity fields in molecular clouds. Turbulence can produce density fluctuation which triggers a gravitational collapse, and it can also produce a non-thermal pressure against gravity. Therefore, turbulence controls the mode and tempo of star formation. However, despite many years of study, the properties of turbulence remain poorly understood. As part of the Taeduk Radio Astronomy Observatory (TRAO) Key Science Program (KSP), "apping Turbulent properties In star-forming MolEcular clouds down to the Sonic scale (TIMES; PI: Jeong-Eun Lee)", we have mapped two star-forming clouds, the Orion A and the ${\rho}$ Ophiuchus molecular clouds, in 3 sets of lines (13CO 1-0/C18O 1-0, HCN 1-0/HCO+ 1-0, and CS 2-1/N2H+ 1-0) using the TRAO 14-m telescope. We aim to map entire clouds with a high-velocity resolution (~0.05 km/s) to compare turbulent properties between two different star-forming environments. We will present the preliminary results using a statistical method, Principal Component Analysis (PCA), that is a useful tool to represent turbulent power spectrum.

This review article summarizes results of recent viscoelastic and dielectric studies for entangled cis-polyisoprene (PI) chains. The PI chains have the so-called type-A dipoles parallel along the chain backbone, and their slow viscoelastic and dielectric relaxation processes reflect the same global chain motion. However, this motion is differently averaged in the viscoelastic and dielectric properties, the former representing the isochronal orientational anisotropy of individual entanglement segments while the latter detecting the orientational correlation of the segments at two separate times (0 and t). On the basis of this difference, the viscoelastic and dielectric data of the entangled PI chains were compared to elucidate detailed features of the chain dynamics. Specifically, the molecular picture of dynamic tube dilation (DTD) incorporated in recent models was tested for linear and star PI chain. The comparison revealed that the DTD picture was valid for linear PI chains but failed for the star PI chains in the dominant part of the terminal relaxation. The failure for the star chains was related to the pre-requisite for the DTD process, rapid equilibration of successive entanglement segments through their constraint release (CR) motion: For the star chains, the dilated tube diameter expected in the terminal regime was considerably large because of a broad distribution of motional modes of the chains, so that the CR-equilibration required for DTD could not occur in time. The terminal relaxation of the star chain appeared to occur through the CR process before the expected DTD process was completed. The situation was different for the linear chain exhibiting narrowly distributed motional modes. The dilated tube expected for the linear chain was rather thin and the required CR-equilibration occurred in time, resulting in the success of the DTD picture. These detailed features of the chain dynamics was revealed only when the viscoelastic and dielectric properties were compared, demonstrating the importance of this comparison.

We present wide-field $JHK_s$-band photometric observations of the three compact H II regions G48.9-0.3, G49.0-0.3, and G49.2-0.3 in the active star-forming region W51B. The star clusters inside the three compact H II regions show the excess number of stars in the $J-K_s$ histograms compared with reference fields. While the mean color excess ratio $(E_{J-H}/E_{H-K_s})$ of the three compact H II regions are similar to ${\sim}2.07$, the visual extinctions toward them are somewhat different: ${\sim}17$ mag for G48.9-0.3 and G49.0-0.3; ${\sim}23$ mag for G49.2-0.3. Based on their sizes and brightnesses, we suggest that the age of each compact H II region is ${\leq}2\;Myr$. The inferred total stellar mass, ${\sim}1.4{\times}10^4M_{\odot}$, of W51B makes it one of the most active star forming regions in the Galaxy with the star formation efficiency of ${\sim}10%$.
