The challenge for sustainability educational programs lies in how to imbue students with the strong motivation necessary to move the world in a more sustainable direction. Five universities in Japan have mutually collaborated in the design and development of a unique curriculum and education system for sustainability science since 2008. Specifically, they have developed a common and remote lecture system called the “Frontier of sustainability science” (FSS). This paper discusses the concepts and challenges of FSS and how it was organized to teach students to actively learn how to work with people of various disciplines to realize interdisciplinarity. 相似文献

Reduction of dioxin emission by a quench reactor with lime spray was investigated in relation to post furnace formation pathways. Results showed that the quench reactor performed to supress post furnace reaction of precursor molecules to form selected congeners of PCDD and PCDF. 相似文献

Removal experiments of phenol,aniline,2,4-dichlorophenol,nonylphenol and bisphenol A(BPA) using Spirodela polyrrhizabacterial associations revealed that all compounds but BPA underwent accelerated removal.The mechanisms differed depending on the substrates.It was found that S.polyrrhiza has a great ability to release phenolic compound-rich root exudates,and the exudates seem to stimulate bacterial degradation of a variety of aromatic compounds. 相似文献

Green construction is gaining increasing attention in the global context. However, the construction of sustainable green buildings
and environments involves different tools and systems and diverse perspectives. Therefore, the development of environmental
assessment tools is an important task for managing green housing and green building projects. In this paper, we discuss the
benefits, limitations, and future directions of the assessment framework. There are four characteristics of building environmental
assessment, i.e., comprehensiveness, design guideline, signaling, and communication tools, which afford both benefits and
limitations. We illustrate the role of the assessment framework as a hub promoting integration of diverse knowledge, as a
design guideline encouraging better design and action, as signaling environmentally friendly design and action, and as a communication
tool. On the other hand, there are limitations, such as the use of a mixture of quantitative and qualitative measures, ambiguity
of weighing, lack of financial evaluation, and lack of involvement of diverse disciplines and stakeholders. To develop an
effective assessment framework, the following three factors must be considered: knowledge, power, and implementation. We propose
that knowledge innovation, a credible approach for a salient solution, and collective action represent the future challenges
of the assessment framework. 相似文献

Humanity faces an increasing possibility that unusual and extreme natural disasters will increase, compounded with climate
change, including global warming. These compound events are designated as compounded natural hazards in this study. A methodology
must be developed for predicting what events and risks will confront future societies, to propose countermeasures and adaptation
strategies against these events, and to evaluate the influences of compound disasters on infrastructure which is particularly
situated near coasts and rivers. Based on the above-stated background and demands, this study was undertaken with the intention
of upgrading the methodology for estimating effects on infrastructure of compound events such as increased typhoon and rainfall
severity caused by global warming occurring concurrently with a great earthquake in Japan. Such a methodology is expected
to contribute to progress in the fields of natural disaster mitigation and land preservation, particularly benefiting coastal
and river areas in Japan. Additionally in this study, risk and economic loss analyses for the possible occurrence of compound
disasters for coastal infrastructure and foundations are produced for establishing environmental strategies at the governmental
level. The authors further propose adaptation strategies and techniques as countermeasures against these events. 相似文献

Human breast milk samples collected in 2007–2008 from four countries, Vietnam (Hanoi), China (Beijing), Korea (Seoul) and Japan (Sendai, Kyoto and Takayama), were analyzed for persistent organic pollutants (POPs) such as dichlorodiphenyltrichloroethane and its metabolites (DDTs), chlordane-related compounds (CHLs), hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). Comparing with previous surveys, the present study indicates that the DDTs in breast milk from China and Vietnam had gradually decreased during the last decade, but were still 5–10 times higher than those in other nations. The ratios of p,p′-DDE/p,p′-DDT and o,p′-DDT/p,p′-DDT were higher in Beijing than in the other countries, suggesting that there is less fresh intake of commercial DDT products and a possible exposure to dicofol in China. CHL and PCB levels were relatively higher in mothers from Japan, whereas β-HCH and HCB were more common in Chinese women. In Japan, it is suspected that mothers in the urban/coastal area (Sendai) were more continuously exposed to organochlorine pesticides (OCPs) than mothers in the rural/inland area (Takayama). In addition, OCP levels in primiparae were significantly higher than those in multiparae from Japan and Korea. These indicate that both parity and regional factors are major determinants of the levels of OCPs and PCBs in human milk. On the other hand, higher concentrations of PBDEs were observed in mothers' milk from Korea. The congener was dominated by BDE-47 (43–54%), followed by BDE-153 (23–33%) in all regions except for Beijing where BDE-28 (23%) was relatively abundant. In Japanese breast milk, regional and parity-dependent distributions were not observed for PBDEs. Among PBDE congeners, age-dependency was observed for BDE-153, which was negatively correlated (p < 0.05) to the age of mothers in Kyoto (17 participants were housewives), while it increased with age in Sendai (10 participants were clerks). No such correlation was seen for BDE-47, indicating that BDE-47 was ingested and assimilated via different kinetics or routes from BDE-153 in Japan. 相似文献

Cosmic-ray-produced (CP) nuclides with half-lives shorter than 21h were measured in rainwater by ultra-low-background gamma spectrometry at Ogoya Underground Laboratory. As levels of CP nuclides are extremely low and their half-lives are very short, quick sampling methods for a large volume of rainwater and rapid chemical separations by ion exchange method were developed. The nuclides measured were short-lived (24)Na, (28)Mg, (38)S, (38)Cl, (39)Cl, as well as nuclides with longer half-lives (7)Be and (22)Na. The number of atoms of CP nuclides in rainwater were evaluated to range from 30 to 1500L(-1) for (24)Na (n=16, mean; 520 [6.7mBqL(-1)]), 80 to 600L(-1) for (28)Mg (n=13, mean; 260 [2.4mBqL(-1)]), 400 to 1900L(-1) for (39)Cl (n=6, mean; 1200 [250mBqL(-1)]), 1x10(6) to 4x10(7)L(-1) for (7)Be (n=16, mean; 7x10(6) [1.05BqL(-1)]) and 2x10(3) to 1x10(5)L(-1) for (22)Na (n=9, mean; 2x10(4) [0.2mBqL(-1)]). 相似文献
