  • The city of Mokpo suffers lowland inundation damages by sea water flooding even without harsh weather like a typhoon, due to the low level urban infrastructure facilities, oceanic environmental changes by constructions of seadike/seawall and sea level rise caused by global warming. This study performs constructing the simulation system which employs the MIKE21 software. And the system is applied to several typhoon- induced surges which had resulted in inundation at Mokpo. Virtual situation of flooding is simulated in case 59 cm of surge height, which had been occurred actually by RUSA(0215), coincides with Approx. H.H.W. Then the water level of 545 cm corresponds to the extreme high water level(544 cm) for 10 year return period after the construction of Geumho seawall. The results show rapid and broad inundation at Inner-Port, requiring additional preparations for flood protections.

  • Most developing countries are experiencing rapid urbanization and the associated growth of industry and services. Cities are currently absorbing two-thirds of the total population in the developing world. Korea has about 85 percent of urban dwellers. World population will shift from being predominantly rural to predominantly urban around the turn of the century. Although cities play a key role in development process and make more than a proportionate contribution to national economic growth, especially cities are also the main catalysts of economic growth in developing countries, they can also be unhealthy, inefficient, and inequitable places to live. Most developing countries are increasingly unable to provide basic environmental infrastructure and services, whether in the megacities or in secondary urban centers. Of particular concern is the strain on natural resources brought by the increasing number of people, cars, and factories. They are generating ever greater amounts of urban wastes and emissions. They also exceed the capacity of regulatory authorities to control them and of nature to assimilate them. The environmental consequences are translated into direct negative impacts on human health, the quality of life, the productivity of the city, and the surrounding ecosystems. Environmental degradation threatens the long tenn availability and quality of natural resources critical to economic growth. Cities, with their higher and growing per capita energy use for domestic, industrial, and transport purpose also contribute a disproportionate share of the emission leading to global warming and acid rain. An important priority is to develop strategic approaches for managing the urban environment. The design of appropriate and lasting strategic responses requires first an understanding of the underlying causes of urban environmental deterioration, it is necessary that longer tenn objectives should be set for urban area to avoid irreversible ecological damage and to ensure lasting economic development. As a means to the preventive policies against the adverse effect, environmental impact assessment (EIA) serve to identify a project's possible environmental consequences early enough to allow their being taken into consideration in the decision making process for urban planning. This paper describes some considerations of EIA for urban planning-scoping, assessment process, measurement and prediction of impacts, pollution controls and supervision, and system planning for environmental preservation.

  • Nowadays, global wedding dress companies are interested in the Chinese wedding market because of expectations in consumption patterns of the post 80's generation. Therefore, wedding behavior, selection criteria for wedding dresses, and favored image by segmented groups targeting 20's to 30's Chinese women were studied to help the Korean wedding dress industry to establish their business in China. The survey was conducted in Shanghai city and three neighboring cities-Wuxi, Zhengziang, and Hangzhou-, and the primary data were analyzed using the SPSS program. As results, Chinese women thought that the wedding ceremony should be elegant and dignified, and they wanted to choose their favorite style rather than a recommended style. The criteria of selection were classified into four factors. Overall image and well fitting with their face and body were the most important factors in the selection of wedding dress. The most favored image was unique/novel image. Several favored images for their wedding dress were significantly different by occasion (ceremony day and photo shoot day) and education level. People of higher education level preferred more luxurious and classic image during the ceremony, and a classic and gorgeous image on the photo shoot day. A white dress and a colored dress for weddings were favored more than the Chinese traditional dress on both occasions. There was also a significant difference between general consumers and the wedding business employees in the quantity of wanted wedding dress.

  • There is growing interest in solar power generation due to global warming. As a result, demand for polysilicon, which is the core material for solar cells, is increasing day by day. As the market grows, large and small accidents occurred in the production process. In 2013, hydrochloric acid leaked from the polysilicon manufacturing plant in SangJu. In 2014, a fire occurred at a polysilicon manufacturing plant in Yeosu, and in 2015, STC(Silicon Tetrachloride) leaked at a polysilicon manufacturing plant in Gunsan City. Leakage of chemicals in the polysilicon manufacturing process can affect not only the workplace but also the surrounding area. Therefore, in this study, we identified the hazardous materials used in the polysilicon manufacturing process and quantitatively estimate the amount of leakage and extent of damage when the worst case scenario is applied. As a result, the damage distance by explosion was estimated to be 726 m, and the damage distance to toxicity was estimated to be 4,500 m. And, if TCS(Trichlorosilane), STC(Silicon Tetrachloride), DCS(Dichlorosilane) leaks into the air and reacts with water to generate HCl, the damage distance is predicted to 5.7 km.

  • Vegetation carbon sequestration and regeneration are the two major parameters of forest research. In this study, we analyzed the vegetation carbon stock and regeneration of community-managed pine plantation of Kathmandu, central Nepal. Vegetation data were collected from 40 circular plots of 10 m radius (for the tree) and 1m radius (for seedling) applying a stratified random sampling and nested quadrat method. The carbon stock was estimated by Chave allometric model and estimated carbon stock was converted into CO2 equivalents. Density-diameter (d-d) curve was also prepared to check the regeneration status and stability of the plantation. A d-d curve indicates the good regeneration status of the forest with a stable population in each size class. Diversity of trees was very low, only two tree species Pinus roxburghii and Eucalyptus citriodora occurred in the sample plots. Pine was the dominant tree in terms of density, basal area, biomass, carbon stock and CO2 stock than the eucalyptus. The basal area, carbon stock and CO2 stock of forest was 33±1.0 ㎡ ha-1, 108±5.0 Mg ha-1 and 394±18 Mg ha-1, respectively. Seedling and tree density of the plantation was 4,965 ha-1 and 339 ha-1 respectively. The forest carbon stock showed a positive relationship with biomass, tree diameter, height and basal area but no relationship with tree density. Canopy cover and tree diameter have a negative effect on seedling density and regeneration. In conclusion, the community forest has a stable population in each size class, sequestering a significant amount of carbon and CO2 emitted from densely populated Kathmandu metro city as the forest biomass hence have a potentiality to mitigate the global climate change.

  • This article addresses potential errors in accounting greenhouse gas (GHG) emissions based on the International Council for Local Environmental Initiatives' (ICLEI's) International Local Government Greenhouse Gas Emissions Analysis Protocol (IEAP). The IEAP seems to provide practical guidelines for local governments so that they can measure their GHG emissions. The outcomes are immediately convertible for any national GHG inventory analysis when one is constructed based on the methodology drafted by Intergovernmental Panel on Climate Change. Further, it provides a societal foundation at the global level in order for local governments to collectively deal with 'double-counting' and 'allocation' problems. However, ICLEI's IEAP overlooks two major issues: (1) the protocol does not consider carbon dioxide emissions due to burning biological fuel as a type of GHG emission; and (2) it overlooks the possibility of indirect double-counting when producing emission factors at the local level. Thus, the limitations must be fixed so that the local governments can measure their GHG emissions more precisely, while the accurate GHG inventory will ultimately support reducing the local governments' emissions to mitigate anthropogenic climate change.

  • Purpose: This study aimed to identify a relationship between the communication competence and social anxiety in nursing students. Methods: With a cross-sectional survey, a convenience sampling of 303 nursing students was taken from P-university in Y-city. The instrument for the study was a questionnaire that is consisted of the general characteristics, an Interaction Anxiousness Scale (IAS) and a Global Interpersonal Communication Competence Scale (GICC). Data was analyzed using descriptive statistics, t-test, one-way ANOVA, Kruskal-Wallis, Pearson's correlation coefficients and stepwise multiple regression with SPSS version 21.0. Results: The mean score of the IAS was $41.89{\pm}8.74$ and the GICC was $3.51{\pm}0.34$. Communication competence significantly differed by the satisfaction of major (F=10.86, p<.001). In addition, the satisfaction of interpersonal relationships was significantly different in both communication competence (F=17.52, p<.001) and social anxiety (F=23.85, p<.001). Social anxiety had a negative correlation with communication competence (r=-.48, p<.001). Social anxiety accounted for 55.3% of the variance -social relaxation (${\beta}$=-.62), assertiveness (${\beta}$=-.18), interaction management (${\beta}$=.14) and efficiency (${\beta}$=-.13)- of communication competence's subcategories. Conclusion: It was found that communication competence has an influence on social anxiety. Therefore, education programs are needed to promote communication competence for a decline of social anxiety in nursing students.
