For sustainable and responsible development of nanomaterials technology, the establishment of ethical system for sound social acceptance of the technology as well as the development of the technology itself is necessary. In this paper, global efforts to identify and resolve the ethical issues regarding nanotechnology is reviewed, in particular the environmental, health and safety issues in nanomaterials, and the tools such as communication and engagement of stakeholders, regulations, certifications and workplace guidelines are scrutinized. Finally the policy recommendations for the establishment of ethical systems for safe usage of nanomaterials.

Sicard, Yves ;
Journal of the Korean Vacuum Society, volume 19, issue 6, 2010, Pages 408~414
DOI : 10.5757/JKVS.2010.19.6.408
For sustainable and responsible development of nanotechnology, the risk issues in nanomaterials must be properly addressed despite the lack of relevant knowledge and regulations. In this paper, `Nanosmile` as an example of web-based tool for education and dialogue for the risk issues, is introduced. First developed at Atomic Energy Commissary (CEA) for in-house training, Nanosmile was integrated to European project NanoSafe2 in 2006 and evolved into an interactive website opening to the public at large. The feedback during the training process, perspectives and limitations of the website are also presented.

Lee, Jung-Won ;
Journal of the Korean Vacuum Society, volume 19, issue 6, 2010, Pages 415~422

Recently as the reports on toxicity of some nanomaterials and the nanoproducts containing these nanomaterials are rapidly increasing, the safety management issues about nanomaterials and nanoproducts are emerging hot. Especially safety in the workplace and that of consumers and the protection of environment, in other words safeties throughout the life-cycle of nanomaterials and products become core issues. Despite the importance of such a safety management, however, it is very difficult to construct the hard regulatory framework for safety, owing to uncertainties and potentialities of nano-risk. In this paper I will look around the ethical principles and guidelines for safety management which are preferentially required before going into the discussion on the construction of hard-regulation such as law and something like that. Under the circumstance that hard-regulations for safety management are not implementable, these principles and guidelines are expected to play a leading part in building the responsible risk-governance framework for nanomaterials and nanoproducts, and finally to become a cornerstone of the hard risk-governance framework.

In order to teach the accumulated knowledge of nanoscience, nanoengineering and nanotechnology to graduate school students and young scientists with the sense of public engagement, Osaka University started from 2004 to prepare and offer various kinds of education and training programs such as trans-disciplinary graduate-school minor program, evening course refresher program, short-term international research training program, etc. It offers a series of lectures, partly broadcasted live to satellite classrooms. In addition, the students can join intensive hands-on training programs using modern facilities, allowing them to design, fabricate, measure, characterize and functionalize nanomaterials and nanodevices. In addition, there are four specially designed lectures and research training programs aimed for nanocommunication including social, legal and ethical relationship: "Nanotechnology Career-up Lectures", "Social Engagement on Nanotechnology", "Road Map Design on Nanotechnology", and "Project-Aimed Learning and Training Programs (PAL)". The outline of the whole programs is described together with the specialized programs for nanocommunication.

The Center for Nanotechnology in Society at Arizona State University (CNS-ASU) is a Nano-scale Science and Engineering Center (NSEC) funded by the US National Science Foundation (NSF). It implements an agenda of "real-time technology assessment" (RTTA) in pursuit of a strategic vision of the "anticipatory governance" of nanotechnologies. To achieve this vision, CNS-ASU unifies research programs not only across several universities but also across three critical, component activities: foresight (of plausible future scenarios), integration (of social science and humanities research with nano-scale science and engineering), and engagement (of publics in deliberations). CNS-ASU also performs educational and training activities as well as public outreach and informal science education. This paper elaborates the Center`s strategic vision of anticipatory governance and its component activities, especially in the context of extending the concerns of societal dimensions research beyond the traditional risk paradigm.

Our team carried out a new program for public engagement on nanotechnology in Korea. We chose 22 monitors, who majored in science or technology and graduated from universities long time ago. Most of them were married and housewives. This `focus group` had not only general knowledge about science or technology but also much interest in social activities. The 167 nanoproducts to be monitored were for daily life, e.g. home appliances (washing machine, refrigerator, water purifier, etc), clothing, cosmetics, food, toy, and others. And the period of it was one month. The monitors had a sheet with 10 questions, and filled them out in essay form. All of them submitted 2~3 sheets every weekend to our team. Before monitoring, our team had a meeting for introduction and explanation about the potential risk of nanotechnology as well as benefits from it. Another meeting was held after finishing monitoring to share their experience one another. The main results of the monitoring were as follows: the number of nanoproducts describing both the definition of `nano` and the size of nanomaterials was just 2 (1.2%) the number of them explaining the technical methods enough was 15 (9/0%) the number of them accounting for the reason of functional improvement enough was 14(8.4%); the number of them doubtful as if there would be exaggeration or false knowledge was 27 (16.2%); the number of them commenting potential hazards to human health or environment was almost zero; the number of them describing about safety certification acceptable was 9 (5.4%). The monitors made a proposal containing recommendation to Government and industry. The contents were as follows: industry should make the manual in detail and correctly, Describe Certificate detailed and correctly, Do research on risk and toxicity continually, Educate employee about nanoproducts at consumer`s center; Government should make indication of nanoproducts compulsory, Appoint Certificate Authority and make Certificate Mark guaranteeing the safety on nanoproducts, Make detailed explanation about nanoproducts compulsory.
Risk and Risk Perception of Nanotechnology
Yi, Sang-Wook ;

Nanotechnology is now widely believed to be one of the most influential techno-sciences of the future. Or at least it is believed that way in most of industrial countries including South Korea. Naturally, the governments of these industrial countries are currently investing a sizable portion of their human and material resources in order to go ahead in this prominent area of research. Consequently, nanotechnology in these countries has become one of the social sectors where reasonable accountability is normally called for. I claim that reasonable accountability of nanotechnology should take into account the risk-perception of citizens as regards nanotechnology as well as its risk itself. Risk-perception could be variable, changeable, and prone to be polarized; still we should pay more attention to public risk-perception because it is clearly effective in mobilizing public movements, objective in the intersubjective way, and legitimate in a democratic society.
Magnetic Permeability Measurement of Stainless Steels in Vacuum Chamber Fabrication
Hong, M.S. ; Park, C.D. ;
Journal of the Korean Vacuum Society, volume 19, issue 6, 2010, Pages 460~466
DOI : 10.5757/JKVS.2010.19.6.460
We measured the magnetic properties of stainless steels type 304 and 316L to see if those materials can be used for the applications where non-magnetic materials are required. The results show that the relative permeability of samples was greatly increased during manufacturing processes. After full solution annealing, however the permeability could be reduced to less than 1.02. Thus, the materials may be employed in the low-permeability applications.

Wang, S.J. ; Won, M.S. ; Lee, B.S. ; Kim, S.H. ; Kwak, J.G. ; Jeong, S.H. ; Kim, S.K. ; An, C.Y. ;
Journal of the Korean Vacuum Society, volume 19, issue 6, 2010, Pages 467~474
DOI : 10.5757/JKVS.2010.19.6.467
Packet propagation and absorption for the 28 GHz superconducting ECRIS under developing by KBSI Pusan center is analyzed with limited parameter range. The microwave power generated by 28 GHz gyrotron is axially injected to the plasma cavity through waveguide system. According to the analytical ray tracing calculation, the wave packet launched quasi-longitudinally at a high magnetic field side changes its direction from outward to inward as it is approaching resonance layer. Therefore, initially diverging wave does not likely hit a conducting surface before absorbing by electron cyclotron resonance. Also, absorption by plasma with moderate electron density is so strong that reflection by an extraction plate may not be expected.

ZnO nano-fibrous thin films with various precursor concentrations ranging from 0.2 to 1.0 mol (M) were grown by spin-coating method and effects of the precursor concentration on surface and optical properties of the ZnO nano-ribrous thin films were investigated by using scanning electron microscopy (SEM) and photoluminescence (PL). ZnO nuclei were formed at the precursor concentration below 0.4 M and the ZnO nano-fibrous thin films were grown at the precursor concentration above 0.6 M. Further increase in the precursor concentration, the thickness of the ZnO nano-fibrous thin films is gradually increased. The intensity and the full-width at half-maximum (FWHM) of the near-band-edge emission (NBE) is increased as the precursor concentration is increased. The deep-level emission (DLE) is red-shifted as the precursor concentration is increased.
The Characterization of Nb
Ge by Slow Positron Annihilation Spectroscopy

Enhance signal-to-noise ratio, slow positron coincidence Doppler Broadening method has been applied to study of characteristics of
superconductor film, which were performed from 20 K to 300 K sample temperature near Tc of it. In this investigation the numerical analysis of the Doppler spectra was employed to the determination of the shape parameter, S, defined as the ratio between the amount of counts in a central portion of the spectrum and the total counts of whole spectrum. The S-parameter values between 0.598 and 0.594 were decreased while the temperature were decreasing, that indicated the voids into the samples. The temperature dependence came from specific positron trapping rate into the vacancy-type defects. It is believed that the positrons annihilate with normal-electrons instead of super-electrons in the Nb3Ge superconductor.

In this study,
films was deposited on to PES (poly(ethersulfon) substrate by using atomic layer deposition as functions of deposition temperature and plasma power. The density and carbon contents of
films was changed by varying process conditions. High density thin films was achieved through optimizing the process conditions. Buffer layer was deposited prior to the processing of upper thin films to avoid PES surface destruction during the high power plasma process and to enhances the tortuous path for water vapor permeation for the defect decoupling effect. The water vapor transmission rate by using MOCON test was investigated to analyze the effect. Water vaper permeation properties was improved by using the inorganic multi-layer passivation layer and activation energy of the water vapor permeation was increased.
