<P><B>Abstract</B></P> <P>Water resources have been threatened by climate change, increasing population, land cover changes in watersheds, urban expansion, and intensive use of freshwater resources. Thus, it is critical to understand the sustainability and security of water resources. This study aims to understand how we can adequately and efficiently quantify water use sustainability at both regional and global scales with an indicator-based approach. A case study of South Korea was examined with the framework widely used to quantify global human water threats. We estimated the human water threat with both global and local datasets, showing that the water security index using global data was adequately correlated with the index for regional data. However, particularly poor associations were found in the investment benefit factors. Furthermore, we examined several different aspects of the index with the local datasets as they have relatively high spatial and temporal resolution. For example, we used cropland percentage, population and moderate water use as surrogate indicators instead of employing the approximately 20 original indicators, and we presented a regression model that was able to capture the spatial variations from the original threat index to some extent. This finding implies that it would be possible to predict water security or sustainability using existing indicator datasets for future periods, although it would require regionally developed relationships between water security and such indicators.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Strong correlations were found between global and regional indicators except for investment benefits. </LI> <LI> Three key indicators represent the majority of the spatial variation in incident threat. </LI> <LI> R25° is the most appropriate spatial resolution for regional analysis. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

The marine unicellular red algal genus Rhodella was established in 1970 by L. V. Evans with a single species R. maculata based on nuclear projections into the pyrenoid. Porphyridium violaceum was described by P. Kornmann in 1965 and transferred to Rhodella by W. Wehrmeyer in 1971 based on plastid features and the non-parietal position of the nucleus. Molecular and fine structural evidences have now revealed that Rhodella maculata and R. violacea are one species, so R. violacea has nomenclatural priority and the correct name is Rhodella violacea (Kornmann) Wehrmeyer. The status of families within Rhodellophyceae was examined. The order Dixoniellales and family Dixoniellaceae are emended to include only Dixoniella and Neorhodella. The order Rhodellales and family Rhodellaceae are emended to include Rhodella and Corynoplastis. Glaucosphaera vacuolata Korshikov and the Glaucosphaeraceae Skuja (1954) with an emended description are transferred to the Glaucosphaerales ord. nov.

소수민족집단의 문화변용은 최근에 매우 중요한 마케팅 연구분야로 각광을 받고 있다. 본 연구는 아시아계 미국인들의 민족중심적 혹은 비 민족중심적인 쇼핑선호도를 개발할 때 영향을 미치는 두 가지 변수인 문화변용과 대인영향력에 대한 민감도의 역할을 파악하는 것을 목적으로 한다. 기존의 연구들은 문화변용의 수준으로서의 민족정체성이 다양한 이민집단 간의 소비패턴의 차이를 가장 설득력 있게 설명할 수 있다는 것을 지적한바 있다. 본 연구의 결과는 민족정체성이 단일차원의 변수가 아니라고 제안한다. 민족정체성과 소비자사회화가 ‘미국인’정체성 보다는 소수민족 자체내의 문화적 배경에 의해 영향을 받는다는 것을 발견했다. 민족정체성과 민족중심적 구매선호도간에는 매우 강한 긍정적인 관계가 있는 것을 발견하였다. 반면에 소비자사회화와 민족중심적 선호도간에는 유의한 직접적 관계를 발견할 수 없었다. 마케터들을 위한 관리적 시사점들이 제안되었다. The acculturation of ethnic minorities is an increasingly important issue. This paper explores the role of two factors which may be related to Asian Americans’ development of preferences for ethnic or non-ethnic shopping: level of acculturation and susceptibility to interpersonal influence. Several prior studies have found that strength of ethnic identification (a measure of level of acculturation) accounts for differences in consumption patterns among immigrant groups. The results of this study suggest that ethnic identification is not a unidimensional construct. Instead, two construct, ethnic identification and consumer socialization are found to be relatedto the level of influence exerted by culturally consistent in-group than "American." A strong positive relationship is found between ethnic identification and ethnocentric purchasing preferences. In contrast, no significant direct relationship between level of consumer socialization and ethnocentric preferences is found. Implications for marketers are discussed.

<P>We report a graphene-based transparent conductive electrode for use in ultraviolet (UV) GaN light emitting diodes (LEDs). A few-layer graphene (FLG) layer was mechanically deposited. UV light at a peak wavelength of 368 nm was successfully emitted by the FLG layer as transparent contact to p-GaN. The emission of UV light through the thin graphene layer was brighter than through the thick graphene layer. The thickness of the graphene layer was characterized by micro-Raman spectroscopy. Our results indicate that this novel graphene-based transparent conductive electrode holds great promise for use in UV optoelectronics for which conventional ITO is less transparent than graphene.</P>
