  • Carbon nanofilaments were deposited on silicon oxide substrate by thermal chemical vapor deposition method. We used $Fe(CO)_5$ as the catalyst for the carbon nanofilaments formation. Around $800^{\circ}C$ substrate temperature, the formation density of carbon nanofilaments could be enhanced by the vacuum sublimation technique of $Fe(CO)_5$, compared with the conventional spin coating technique. Finally, we could achieve the low temperature, as low as $350^{\circ}C$, formation of carbon nanofilaments using the sublimated Fe-complex nanograins with thermal chemical vapor deposition. Detailed morphologies and characteristics of the carbon nanofilaments were investigated. Based on these results, the role of the vacuum sublimation technique for the low temperature deposition of carbon nanofilaments was discussed.

  • The present work was performed to investigate the effect of coiling temperature on the annealed texture in Cu/Nb-added ultra-low-carbon steels. The ultra-low-carbon steels were coiled at 650 and $720^{\circ}C$, respectively. The result showed that the Cu-added ultra-low-carbon steel at a low coiling temperature produced a desirable annealed texture related to good formability. On the other hand, Nb-added ultra-low-carbon steel at a high coiling temperature also produced a desirable texture. This is attributed to the effect of Nb, which retards recrystallization during the coiling process.

  • To internalize climate-related external costs from agricultural production and food consumption Pigou taxes and carbon credits increase private costs for food. Voluntary GHG reduction program for carbon-neutral food can be advantageous over such policy measures since they avoid higher food prices for the poor. The pilot project of low-carbon agriculture certification system is to reduce GHG emissions from agricultural production and enhance the competitiveness of domestic agricultural products. This study examines producers', distributors', and consumers' perceptions of the low-carbon agriculture certification system and analyzes alternatives to promote the low-carbon certificated agricultural products.

  • Recently, as the concern over environmental problem has been serious all over the world, carbon has become a key issue to mitigate the problem. In the field of Architecture, various sustainable assessment systems and LCCO2 assessment strategies have been developed, guiding low carbon building while planning. However, assessment system for low carbon neighborhood, which can be more efficient strategy, is still in the stage of research. In this paper, as a research for low carbon assessment system and planning guideline for neighborhood, scope meeting domestic condition has been set and sustainable assessment system for neighborhood, which is similar to low carbon concept, have been compared. LEED-Neighborhood Development, BREEAM-Communities, CASBEE-Urban Development, and GBCC-Apartment Houses were used for comparison. As a result, it is found that those systems has many differences in judging system, aggregating method, scope of evaluation, and relations with a building assessment system. The concern about carbon is not insufficient yet. Finally, assessment system for low carbon neighborhood, which is not only for establishing the plan, but also for giving guideline at the very first state of the plan, should be developed as fast as passible. With the result of this paper, establishment of assessment criteria and the way to measure quantitative $CO_2$ should be studied forward.

The subjects were 367 high school students in the Incheon area. This cross-sectional survey was conducted using a questionnaire, and data were analyzed with the SPSS 20.0 program. According to the findings, green dietary life recognition were categorized into two sub-factors: 'Eco-friendly traditional dietary life', and 'Life of consideration and thanks'. Low-carbon green life practice was 'Low-carbon green life', and health-related dietary habits were categorized into four sub-factors: 'Vegetables-oriented traditional dietary habits', 'Balanced dietary habits', 'Life practice for health', and 'Various cereals intake'. Green dietary life recognition showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.05), whereas 'Eco-friendly traditional dietary life' had no significant effect on 'Balanced dietary habits'. Low-carbon green life practice showed a significantly positive relationship with all sub-factors of health-related dietary habits (p<0.01). Students who received green growth education showed significantly higher health-related dietary habits than those who did not (p<0.01). Girls showed significantly higher green dietary life recognitions and low-carbon green life practice than boys (p<0.01). Therefore, more green dietary life and low-carbon green life education programs targeting students are need. Voluntary activities, along with green dietary life and low-carbon green life education will help students improve their health-related dietary habits.
