본 연구는 개별 국가 혹은 지역 단위 배출권 거래제도의 국제적 연계 가능성에 대비하기 위해 한 중 일 3국간의 배출권 거래제도 연계 시 예상되는 경제 환경적 영향을 분석하기 위해 수행되었다. 이를 위해 연산가능 일반균형모형을 통해 3국간 배출권 거래제 도입의 경제 환경적 영향을 분석하였다. 분석결과 한 중 일 3국간 탄소시장의 연계는 국가별로 다양한 측면에서 복잡한 영향을 미치게 됨을 확인할 수 있다. 한 중 일 배출권 거래제 연계 시행은 3국 전체의 실질 GDP를 증가시키는 긍정적 효과가 있음에도 불구하고 연계로 인한 이익의 국가간 분배가 불균형적임은 물론 실질 소비나 고용 등의 측면에서는 탄소시장 연계가 3국 전체적으로도 오히려 부정적인 영향을 초래할 수 있다는 점에서 반드시 긍정적인 효과만을 담보하는 것은 아니다. 특히 배출권 매입국인 한국과 일본의 소득 소비 고용 감소 및 에너지 의존도 증가, 배출권 매출국인 중국의 생산 감소 및 해외 이전 가능성은 3국간 탄소시장의 연계의 장애요인으로 작용할 수 있다. 3국간 탄소시장 연계를 통한 긍정적 효과를 최대한 유지하면서 예상되는 부정적 효과를 최소화하기 위해서는 배출권 수입 관세나 수입배출권 할인과 같은 보완적 정책수단의 개발 적용이 필요하다.

Aflatoxin contamination in rice has been documented in a number of studies, and has a high incidence in Asian countries, and as such, there has been a growing interest in alternative biocontrol strategies to address this issue. In this study, 147 strains of yeasts and yeast-like fungi were screened for their potential to produce volatile organic compounds (VOCs) active against Aspergillus flavus strains that produce aflatoxin B₁ (AFB₁). Five strains within four different genera showed greater than 50% growth inhibition of some strains of A. flavus. These were Anthracocystis sp. DMKU-PAL124, Aureobasidium sp. DMKU-PAL120, Aureobasidium sp. DMKU-PAL144, Rhodotorula sp. DMKU-PAL99, and Solicococcus keelungensis DMKU-PAL84. VOCs produced by these microorganisms ranged from 4 to 14 compounds and included alcohols, alkenes, aromatics, esters and furans. The major VOCs produced by the closely related Aureobasidium strains were found to bedistinct. Moreover, 2-phenylethanol was the most abundant compound generated by Aureobasidium sp. DMKU-PAL120, while methyl benzeneacetate was the major compound emitted from Aureobasidium sp. DMKU-PAL144. On the other hand, 2-methyl-1-butanol and 3-methyl-1-butanol were significant compounds produced by the other three genera. These antagonists apparently inhibited A. flavus sporulation and mycelial development. Additionally, the reduction of the AFB1 in the fungal-contaminated rice grains was observed after co-incubation with these VOC-producing strains and ranged from 37.7 ± 8.3% to 60.3 ± 3.4%. Our findings suggest that these same microorganisms are promising biological control agents for use against aflatoxin-producing fungi in rice and other agricultural products.

Disposal of construction wastes poses major challenge to the municipal administration in the developing countries. At the same time new developments in these countries are unscrupulously exploiting the natural resources. The sustainable development requires judicious and careful utilization of natural resources. In this context, reuse of construction and demolition waste can save the global natural resources to greater extent. In this work the bricks and concrete waste from construction sites were crushed to the desired sizes and mixed in various proportions to study its properties in the concrete both in fresh and hardened states. Six mixes of natural and recycled aggregates were used to make the coarse aggregates for the concrete. From each mix nine cylinders were cast, which were tested at 7,14 and 28 days. The properties of concrete with recycled aggregates were compared with the control mix having natural aggregates. The nominal ratio of cement sand and coarse aggregates were kept at 1:2:4 by weight for all mixes. The tests have shown that concrete with recycled aggregates made from old concrete and brick bats provide greater opportunities for reuse of construction wastes in concrete.

The huge amount of demand for feedgrains from this region could not possibly be met by producing countries from the other regions. In order to fulfill this increasing demand for conventional raw materials, an alternative for the conventional raw materials produced in the Asia and Pacific region is becoming increasingly more important. A potential alternative is concentrates or non-conventional concentrates produced locally in relative abundance in this region. These feedstuffs include feed grains, by-products from the milling, sugar industries, brewing and distilling industries. Vegetable, citrus, and animal by-products from abattoir, feather meal and blood meal are also possibilities. In addition to more widespread use of unconventional feed sources, the following approach is recommended to improve utilization and performance. These include establishing the nutritive value of non-conventional feeds, quality control to minimize variability, proper storage and processing to assure the nutritive value and prevent mycotoxin contamination, properly balance amino acids with protein sources, supplementation with synthetic amino acids and the use of enzymes to increase digestibility. Currently, practical applications for these resources in feed formulation are negligible despite the potential. The socio-economic aspects will dominate the use of these non-conventional concentrates. In the future, the feed industry will resolve the problems in using locally available raw feed materials.

Purpose - These days, Korean society with more than 2 million foreigners has made multi-cultural society quickly. Multi-cultural society has become popular and anti multi-cultural phenomenon has grown up gradually against Korea's traditional habits. Research design, data, and methodology - European countries that were said to be multi-cultural society had suffered from terror, riot and other social conflicts. The study examined Koreans' racism and anti multi-cultural emotion to investigate the conditions and causes of anti multi-cultural emotion. Further, this study investigates a prevention of the worst case such as Norway terror and the countermeasures compared to each country's social customs. Results - Koreans are not generous to the foreigners. Foreign countries' cases after failures in multi-cultural society might give future implications on multi-cultural society in Korea. Conclusions - Korean society have not produced new one by introducing another races, nationality and culture not cognizing failure experiences of multi-culturalism like Europe. Nonetheless, Korean society shall not give up multi-culturalism. Korean society shall prepare for multi-culturalism society to lessen social conflict as much as possible and not to neglect anti culturalism emotion producing social conflict, and shall investigate the related causes to lessen anti multi-culturalism emotion and to integrate Korean style of multi-culturalism society for Korea as a tool of nation management.

The main reason that drives many developing countries to pursue waste-to-energy (WtE) technologies is that it produces energy while eliminating build-up of large quantities of wastes, at a time, when oil and gas reserves are declining. The rate of generation of municipal solid wastes (MSW) in any given country depends on many factors including economy, population, and modernization of industry and infrastructure developments. The United Arab Emirates (UAE) is a federation of seven emirates that has grown to be one of the Middle East's most important economic centers. UAE has also become one of the highest waste producing countries due to fast development and growth; thus, UAE pursue modern technologies to covert generated wastes into energy. In this communication, the status of on-going waste to energy projects and WtE plants that are currently under design and construction in UAE are discussed. The need for development of WtE technologies is presented based on the literature, reports, economics and the environmental regulations.

Traditional medicine in Asian countries show similarity according to geography, building up their own medical tradition upon indigenous cultural background. Mongolian medicine, in particular, displays district fusion of several medical systems accepted from neighboring countries adding to their traditional system. Those are Mongol Dhom medicine, acupuncture and moxibustion medicine, medicine of "Four Medical Tantras (四部醫典)", and combined system of Mongolian and biomedicine. Compared to East asian medicine, this is a different kind of diversity or hybridity resulting from idiosyncrasy of nomadic culture. Each current of Mongolian medical tradition has its own origin of historical backdrop. Mongol Dhom originated from ancient nomadic life, and medicine of "Four Medical Tantras (四部醫典)" was formed along with transmission of Tibetan Buddhism. Acupuncture and moxibustion is directly related to Chinese medical tradition, however, moxibustion is also referred to be regional origination. Lastly, biomedicine was transplanted during the modernization era, encouraging scientific approach toward Mongolian traditional medicine and producing combined medical practice. It is effective to derive each particular aspects of Mongolian medicine and analyze its specificity, in order to properly understand current Mongolian medical system. This paper aims at discovering socio-cultural meanings of each current and their nomadic feature beneath the diversity.

Circumvention refers to the situation in which exporters try to circumvent import restrictions by setting up factories in third countries and assembling and producing parts locally. Circumvention dumping eliminates the impacts of existing anti-dumping measures, and major countries are introducing anti-circumvention dumping laws to address this problem. If the act of the exporting country is recognized as a circumvention dumping activity, anti-dumping duties are applied retroactively to the imported goods or components. Evasion is an act of importation that results in the reduction or non-application of cash deposits, securities, or anti-dumping or countervailing duties, in a manner that is substantive or false, substantive or omission. In this article, we reviewed the contents and examples of the anti-circumvention measures by the US Department of Commerce (DOC), the International Trade Commission (ITC), and the Anti-Evasion measures by the CBP. The CBP examples show how much inference can be made about which parts of the CBP's investigations, and in what ways. The enactment of the EAPA created an environment in which the role of the CBP was directly guaranteed, and it was possible to apply adverse inferences to those who did not respond to requests for information, resulting in stronger CBP's authority. Therefore, it is advisable for Korea to examine the introduction of domestic laws, such as the bypass anti-dumping system, in order to cope with unfair trade practices that undermine and neutralize the effects of anti-dumping measures.

Background: This study used bibliometric analysis of articles published about the topic of regional anesthesia from 1980-2019 with the aim of determining which countries, organizations, and authors were effective, engaged in international cooperation, and had the most cited articles and journals. Methods: All articles published from 1980-2019 included in the Web of Science database and found using the keywords regional anesthesia/anaesthesia, spinal anesthesia/anaesthesia, epidural anesthesia/anaesthesia, neuraxial anesthesia/anaesthesia, combined spinal-epidural, and peripheral nerve block in the title section had bibliometric analysis performed. Correlations between the number of publications from a country with gross domestic product (GDP), gross domestic product (at purchasing power parity) per capita (GDP PPP), and human development index (HDI) values were investigated with the Spearman correlation coefficient. The number of articles that will be published in the future was estimated with linear regression analysis. Results: Literature screening found 11,156 publications. Of these publications, 6,452 were articles. The top 4 countries producing articles were United States of America (n = 1,583), Germany (585), United Kingdom (510), and Turkey (386). There was a significant positive correlation found between the GDP, GDP PPP, and HDI markers for global countries with publication productivity (r = 0.644, P < 0.001; r = 0.623, P < 0.001, r = 0.542, P < 0.001). The most productive organizations were Harvard University and the University of Toronto. Conclusions: This comprehensive study presenting a holistic summary and evaluation of 6,452 articles about this topic may direct anesthesiologists, doctors, academics, and students interested in this topic.
