Market Based Anti-American Sentiment A Study of Non-Resident Copyright Protection

( James D. Thayer ) 서울대학교 아시아태평양법연구소 2003 Journal of Korean Law Vol.3 No.2

With more than 60 percent of all Korean households having high-speed Internet access, Korea is one of the world``s most wired countries.1) According to the United States Trade Representative (USTR), and others, many Koreans use this high-speed access not only to surf the web but also to trade in pirated goods.2) Many U.S. companies alleging harm from this piracy currently lobby the Korean Government - often through the USTR - to continue to improve the enforcement and establishment of non-resident copyright protection in Korea.3) At a general level, this international struggle between United States producers and Korean consumers is the same struggle that exists between producers and consumers within the United States itself. For example, in the U.S., domestic producers of goods protected by copyright laws lobby the United States government for increased copyright protection. Simultaneously, domestic consumers lobby the same government for increased access to protected goods. This struggle is inherent in the United States constitutional authority that allows for copyright protection in order [t]o promote the progress of science and useful arts.4) That is to say, the constitutional authority behind copyright protection seeks to encourage creativity without unduly hindering the public``s access.5) One difference in this international arena is that Korea``s copyright policy is being heavily influenced by an outside source. The outcome of the struggle between incentive and access in Korea is being largely decided by the United States. Such a model can lead to neglect of domestic Korean consumer interests. Instead of the Korean market dictating Korean copyright policy, U.S. producers of videos, music, and software are. As this paper will discuss, one result of this structure is an increase in anti-American sentiment in Korea.

Marble wastes as amendments to stabilize heavy metals in Zn-Electroplating sludge

Riahi, Khalifa,Chaabane, Safa,Thayer, Bechir Ben Techno-Press 2017 Advances in environmental research Vol.6 No.1

Powdered marble wastes (PMW) generated by Utique marble cutting industries (North of Tunisia) with abundant amounts were used in this study as low-cost materials to investigate the stabilization of heavy metals (Pb, Zn, Fe) in sludge generated from a local Zn-Electroplating factory. Powdered marble wastes were evaluated by means of chemical fractions of heavy metals in sludge and concentrations of heavy metals in leachate from columns to determine their ability to stabilize heavy metals in contaminated sludge. Results indicated that chemical fractions of heavy metals in sludge were affected by application of the PMW mineral materials and pH, however, the effects varied with heavy metals. Application of the powdered marble wastes mineral materials reduced exchangeable metals in the sequence of Pb (60.5%)>Fe (40.5%)>Zn (30.1%). X-ray diffraction and hydro-geochemical transport code PHREEQC analysis were successfully carried out to get a better understanding of the mechanisms of reactive mineral phases involved in reduced exchangeable heavy metals in sludge after PMW material amendments. Therefore, metal immobilization using powdered marble wastes materials is an effective stabilization technique for industrial metallic hydroxide sludge.

Emissions of Glyoxal and Other Carbonyl Compounds from Agricultural Biomass Burning Plumes Sampled by Aircraft

Zarzana, Kyle J.,Min, Kyung-Eun,Washenfelder, Rebecca A.,Kaiser, Jennifer,Krawiec-Thayer, Mitchell,Peischl, Jeff,Neuman, J. Andrew,Nowak, John B.,Wagner, Nicholas L.,Dubè,, William P.,St. Clair, American Chemical Society 2017 Environmental science & technology Vol.51 No.20

<P>We report enhancements of glyoxal and methylglyoxal relative to carbon monoxide and formaldehyde in agricultural biomass burning plumes intercepted by the NOAA WP-3D aircraft during the 2013 Southeast Nexus and 2015 Shale Oil and Natural Gas Nexus campaigns. Glyoxal and methylglyoxal were measured using broadband cavity enhanced spectroscopy, which for glyoxal provides a highly selective and sensitive measurement. While enhancement ratios of other species such as methane and formaldehyde were consistent with previous measurements, glyoxal enhancements relative to carbon monoxide averaged 0.0016 +/- 0.0009, a factor of 4 lower than values used in global models. Glyoxal enhancements relative to formaldehyde were 30 times lower than previously reported, averaging 0.038 +/- 0.02. Several glyoxal loss processes such as photolysis, reactions with hydroxyl radicals, and aerosol uptake were found to be insufficient to explain the lower measured values of glyoxal relative to other biomass burning trace gases, indicating that glyoxal emissions from agricultural biomass burning may be significantly overestimated. Methylglyoxal enhancements were three to six times higher than reported in other recent studies, but spectral interferences from other substituted dicarbyonyls introduce an estimated correction factor of 2 and at least a 25% uncertainty, such that accurate measurements of the enhancements are difficult.</P>

센서-구조 일체형 복합재료 구조물 제작 방법

한대현 ( Dae Hyun Han ),강래형 ( Lae Hyong Kang ),( Jordan Thayer ),( Chales Farrar ) 한국복합재료학회 2015 Composites research Vol.28 No.4

본 연구는 복합재료 구조물에 전기-기계 변환 기능을 융합한 센서-구조 일체형 복합재료 구조물 제작 방법에 관한 것으로 복합재료 구조물 자체가 센서 역할을 수행할 수 있도록 하여 구조 스스로 충격이나 진동 신호를 감지하고 손상 위치 또는 손상 정도를 실시간으로 모니터링 할 수 있는 다기능 복합 구조물에 관한 연구이다. 복합재 구조물에 전기-기계 변환 기능을 부여하기 위해 복합재 제작에 사용되는 에폭시 수지 대신 전기-기계 변환기능을 갖는 Pb(Ni1/3Nb2/3)O3-Pb(Zr, Ti)O2 (PNN-PZT) 분말과 에폭시 수지를 1:30 wt% 혼합하여 제작된 스마트 수지를 사용하였다. Hand Lay-up 공법과, VARTM(Vacuum Assisted Resin Transfer Molding) 성형 방법을 이용하여 유리섬유에 스마트 수지를 함침시켜 센서-구조 일체형 복합재료 구조물을 제작하였다. 구조물을 센서로 사용하기위해 시편의 윗면과 아랫면에 전도성 도료를 사용하여 전극을 제작하였고, 고전압 앰프를 이용하여 상온에서 30분간 4kV/mm의 전계로 분극 처리를 수행하였다. 이후 충격망치를 사용하여 시편에 충격을 가했을 때 출력되는 전기 신호와 충격망치 신호를 비교하여 충격 신호 감응 및 감도를 측정하고 그 결과를 기술하였다. A composite structure was fabricated with embedded impact detection capabilities for applications in Structural Health Monitoring (SHM). By embedding sensor functionality in the composite, the structure can successfully perform impact localization in real time. Smart resin, composed of Pb(Ni1/3Nb2/3)O3-Pb(Zr, Ti)O2 (PNNPZT) powder and epoxy resin with 1:30 wt%, was used instead of conventional epoxy resin in order to activate the sensor function in the composite structure. The embedded impact sensor in the composite was fabricated using Hand Lay-up and Vacuum Assisted Resin Transfer Molding(VARTM) methods to inject the smart resin into the glass-fiber fabric. The electrodes were fabricated using silver paste on both the upper and bottom sides of the specimen, then poling treatment was conducted to activate the sensor function using a high voltage amplifier at 4 kV/mm for 30 min at room temperature. The composite’s piezoelectric sensitivity was measured to be 35.13 mV/N by comparing the impact force signals from an impact hammer with the corresponding output voltage from the sensor. Because impact sensor functionality was successfully embedded in the composite structure, various applications of this technique in the SHM industry are anticipated. In particular, impact localization on large-scale composite structures with complex geometries is feasible using this composite embedded impact sensor.
