  • Based on the tide gauge data from the Permanent Service for Meau Sea Level (PSMSL) collected at 23 locations in the Korean coast, the long-term sea-level trend was computed using a simple linear regression fit over the recorded length of the monthly mean sea-level data. The computed sea-level trend was also corrected for the vertical land movement due to post glacial rebound(PGR) using the ICE-4G(VM2) model output. It was found that the PGR-corrected sea-level trend near Korea was 2.310 $\pm$ 2.220 mm/yr, which is higher than the global average at 1.0∼2.0mm/yr, as assessed by the Intergovernmental Panel on Climate Change(IPCC). The regional distribution of the long-term sea-level trend near Korea revealed that the South Sea had the largest sea-level rise followed by the West Sea and East Sea, respectively, supporting the results of the previous study by Seo et al. However, due to the relatively short record period and large spatial variability, the sea-level trend from the tide gauge data for the Korean coast could be biased with a steric sea-level rise by the global warming during the 20th century.

  • This paper focused on examining the middle school students' perceptions of characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend, behavior will) of 10 global and 8 local environmental issues. Subjects(N=516) demonstrated by completing a survey that they perceived the characteristics of issues differently on global and local scales, and to a degree those characteristics are related. First, middle school students' perceptions of global and local environmental issues were above mid-point mainly, and perceptions of local environmental issues were higher than those of global environmental issues. At perceptions of characteristics, They perceived that the personal knowledge of global environmental issues were higher than those of local issues, that the human responsibility effects on global environmental issues more than local environmental issues, that global environmental issues in the future, will be more serious. For each environmental issues, the perception of global warming among the global issues was highest, the perception of yellow dust and air pollution among the local issues was highest. For perceptions of characteristics, behavior will to solve the environmental issues was lower than that of 4 characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend). Second, there was significant difference of the perceptions of two scale environmental issues for area and sex. It showed that Seoul students' perceptions were higher than Kong-ju students' perceptions according to area, and that girl students' perceptions were higher than boy students' perceptions according to sex. Third, correlations among issues were significant. Especially, it was positive relationship between knowledge and human responsibility, human responsibility and impact on personal human responsibility and predicted trend. Educators and communicators should take into account the perceived characteristics of environmental issues and choose effective information sources and teaching methods to improve students' understanding of human-induced environmental changes.

  • This study analyzes the Asian, African and Latin American cultural hybrids in modem fashion, and offers a direction for desirable cultural hybrids in modem fashion. First, the cultural hybrids have been considered in two aspect: global hybrids and structural hybrids. Second, the trends of Asian, African and Latin American cultural hybrids have been interpreted differently depending on the cultural backgrounds of each area. However, the cultural hybrid representing the change of tradition in Asia, Africa and Latin America is a common trend, and is used to describe the social changes. Third, this study examines the global hybrid trend in modem fashion based on the hybrid trend of Asian, African and Latin American culture found in the four major collections from 2000 S/S to 2005 F/W. Until recently, the exotic images have been determined in the viewpoint of Western world, and utilization by the world-renowned designers in the four major collections plays the major role in converting the regional cultural elements into global ones. Fourth, this study also examines the structural hybrids in modem fashion based on the hybrid trend found in Asian, African and Latin American designer collections between 2000 S/S and 2005 F/W. The works which are connected to the world trend, but are also rooted from the cultural and regional traditions demonstrate the globalization of the Asian, African and Latin American fashion. Fashion is a messenger of a culture, and its importance as a symbol of a cultural trend is growing.

  • In this paper, we reported that the global trend of cement production and utilization as raw materials and as a fuel. As we know, cement is one of the significant materials required for the construction industry. The recent trend of rising urbanization, both the cement and construction industry played a vital role. The cement industry is a major sustainable infrastructure for the countries. Currently, China producing cement half of the world's cement production. During the year 2018, Korea producing cements nearly 57.5 million metric tons. Waste materials are used as circular resources and also having tremendous benefits for cement production. Another important use of these circular resources is fuel for the cement industry. There is a large potential benefit of the cement industry, but it's creating a severe environmental threat. The cement industry contributes to the major emissions of CO2. This leads the global warming. As per the Paris agreement, the Korean government initiated the recycling policy of waste materials and also the utilization of circular resources for the prevention of limited natural resources and also the global warming effect.

  • Using results from an Earth System model, we investigated change in primary production in the East China Sea, under a global warming scenario. As global warming progresses, the vertical stratification of water becomes stronger, and nutrient supply from the lower part to the upper part is reduced. Consequently, so is the primary production. In addition to the warming trend, there is strong decadal to interdecadal scale variability, and it takes a few decades before the warming trend surpasses natural variability. Thus, it would be very hard to investigate the global warming trend using data of several years' length.

  • The purpose of this study is to explore the effectiveness of marketing strategies of children's clothing line for global SPA brands among Korean consumers. The following factors were evaluated as the dependent variables: benefits sought, store attributes, and brand loyalty. We employed a survey method to test our research questions. The subjects of our survey were mothers with preschool kids between 2 and 7 years who had purchase experiences of children's clothing lines of global SPA brands. The major findings are as follows: First, among the three factors of benefits sought ('trend'/'brand value'/'practicality'), the 'trend' factor only positively impacted the 'product' factor, which is part of the store attributes. 'Practicality' and 'trend' factors had a positive effect on the 'service' factor of store attributes. However, all three factors of benefits sought had no impact on the 'store' factor, and 'practicality' and 'trend' factors had positive effects on the price factor of store attributes. Second, 'practicality' and 'trend' factors among the three factors of benefits sought, had positive effects on brand loyalty. Third, the 'product', 'price', 'store', and 'service' factors had a significant positive effect on brand loyalty in decreasing order. Suggestions from our results for national SPA brands are as follows: National SPA children's clothing lines should focus more on unique designs and unique marketing strategies better reflecting Korean consumers' interest and needs in competing with their global counterparts.

  • Recently, several satellite data analyses projects and numerical weather prediction (NWP) reanalysis projects have produced the ocean surface Latent Heat Flux (LHF) data sets in the global coverage. Comparisons of these LHF data sets showed substantial discrepancies in the LHF values. Recently, the increase of LHF in during 1970s-1990s over the global ocean is shown by the LHF data that have been developed at the Objective Analyzed Air-Sea Fluxes (OAFlux) project. It is interesting to investigate the existence of the increase of LHF over a global ocean in the other LHF products. It is interesting to investigate the existence of the increase of LHF over a global ocean in the other LHF products. In this study, we assessed the consistencies and discrepancies of the inter-annual variability and decadal trend for the period 1988-2005 among six LHF products ((J-OFURO2, HOAPS3, IFREMER, NCEP1,2 and OAFlux) over the global ocean. As results, all LHF products showed a positive trend. In particular, the positive trend in satellite-based data analyses (J-OFURO2, HOAPS3, IFREMER) is larger than that in reanalysis products (NCEP1/2). Also, the consistencies and discrepancies are shown on the spatial patterns of the LHF trends across the six data sets. The positive trend of LHF is remarkable in the regions of western boundary currents such as the Kuroshio and the Gulf Stream in all LHF data sets. But, the discrepancies are shown on the spatial patterns of the LHF trends in tropics and subtropics. These discrepancies are primarily caused by the differences of the input meteorological state variables, particularly for the air specific humidity, used to calculate LHF.
