본 연구는 포켓몬 시리즈의 남성/남성 지배 포켓몬들과 여성/여성 지배 포켓몬들의 특징을 분석하면서 포켓몬 시리즈의 성 지위에 대해 탐구한다. 1세대부터 8세대까지 802의 포켓몬 캐 릭터가 존재한다. 각 포켓몬들은 태어날 때 다른 성 비율을 지니고 있다: 하나의 포켓몬은 남 성, 여성, 동등, 무성의 “확률”을 지니고 있다. 본 연구를 이러한 포켓몬들은 3가지 기준으로 분 석 한다: 1) 출연 빈도 2) 능력 3) 종류의 다양성, 그리고 이것을 성별의 기준으로 비교한다. 포 켓몬 시리즈는 다른 비디오 게임과 다르게 다양한 캐릭터들을 제공한다. 그러므로 이는 사람들 이 비디오 게임 캐릭터들의 성 지위를 보다 깊고 의미 있게 볼 수 있도록 도와준다.

A coating system derived from the combination of a sodium and a potassium water glass was developed to apply for steel in oxidizing and humidity environments at elevated temperature. Parameters such as filler volume, viscosity or coating thickness were varied to optimize the coatings. The coated specimens were investigated by TGA, SEM/EDS, and XRD to clarify the microstructure morphology and anti-oxidation behavior. Finally, oxidation tests, adhesion tests, thermal shock resistance tests and humidity resistance tests were performed to evaluate the performance of developed coating.

소음 저감을 목적으로 설치되는 방음벽은 크게 흡음판과 방음판으로 나뉘며, 일조 및 경관을 저해하는 방음벽의 문제점을 해결하 고자 투명 방음벽을 설치하는 것이 일반적 추세이다. 방음벽에 사용되는 투명 방음판의 소재는 여러 가지가 있으나 경우에 따라서는 황변현상 과 재질변형 등으로 인해 투명도가 떨어지고 오염이 심해져 오히려 도시미관을 해하기도 한다. 따라서 이러한 단점을 보안하기 위하여 투명 방 음판의 재질을 접합강화유리로의 대체가 가능하다. 본 논문은 메트로 지하철 고가교 상에서의 열차 유발진동에 따른 접합강화유리 방음판의 진동 및 풍하중에 의한 안전성을 분석하고, 접합강화유리 시스템 및 재료에 대한 휨능력 성능시험, 압축강도 및 탄성계수 시험, 충격시험 등을 수행하여 접합강화유리의 방음판으로서의 적정성을 평가하는 데 목적이 있다.

Electrical waste, such as heavy weight waste glass, has become a global concern in terms of resource recycling. At the same time, aggregate is one of the most widely used infrastructure materials, and it is being exhausted. So, in this paper, the heavy weight waste glass is considered as aggregate due to its physical characteristics and chemical composition. From the results, when the heavy weight waste glass substitution ratio increase, the compressive strength and flexural strength decreased.

국내 태양광 시장은 정부의 주도하에 2006년 이후 연평균 50% 이상의 성장률을 보이며 급성장 하였다. 2006년에 22MW였던 태양광 시장은 2012년, 그보다 10배 이상인 279MW의 규모에 이르렀고 2013년에는 330MW가 설치되었다. 그 결과 2006년 36MW에 불과하였던 국내 태양광 누적 설치용량은 6년만인 2012년에 1GW를 돌파하였다. 기존 연구결과를 통해 유추한 결과 폐 태양광 모듈의 발생 시기는 태양광 모듈 수명이 2000년 이전의 생산제품은 10년, 2001년∼2010까지의 생산제품은 15년, 2011년 이후의 생산제품에 대해서는 20년이라고 가정할 때에 대략 2020년 정도가 될 것으로 추측된다. 생산과정에서 발생한 폐 모듈은 물론 기존에 설치된 모듈의 효율저하, 제조시의 불량 및 새로이 개발된 고효율(발전효율 18%이상)패널로의 교체로 모듈의 평균수명이 낮아져 매년 폐기되는 모듈의 양은 기하급수적으로 증가할 것으로 예상된다. 현재까지 처리된 폐 모듈의 양도 최소 5MW으로 추측되며, 2020년부터 처리해야 할 폐 모듈의 양은 백MW단위로, 많은 양의 폐기물이 배출될 것이라 본다. 아직까지 우리나라는 자원 재생에 대한 인식이 부족하여 여러 가지 문제에 당면해 있는 실정이다. 우리나라는 전국적인 회수 체계가 미흡하고 재활용 인식이 낮아 수거자체가 어려울 뿐만 아니라, 도시 광산은 서비스업으로 분류되어 있어 산업단지 내 공장설립이 제한되어 있고, 그 절차 또한 복잡하고 오랜 시간 기다려야하기 때문에 접근이 쉽지 않다. 이에 본 연구는 폐 PV모듈(Photovoltaic module)에서 추출한 저 철분 강화유리 분말을 이용한 콘크리트용 혼화재로서의 활용가능성 알아보고, 최근 환경문제로 대두되어 있는 산업폐기물의 건설 순환자원으로의 재활용방안을 제시하고자 함이 목적이다.

Insulation materials used for building save energy and can be classified into inorganic and organic materials. Organic insulation emits toxic gases in a fire annd has lower water resistance. Inorganic insulation is heavy and has poorer thermal performance than that of organic material. This study evaluated the physical properties and fire resistance of lightweight inorganic insulation foaming material made of waste glass powder. The test results showed that the inorganic material performed well with low density and low thermal conductivity for an insulation material. Foam insulation material manufactured from glass powder was sufficient as a fire-resistant product.

As the industrialization is rapidly growing, the quantities of industrial waste glass have been quickly increased. However the most of them are not recycled. Therefore, it is needed to investigate the possibility of industrial waste glass as concrete material ingredient.

본 실험 논문은 초단유리섬유(milled glass fibers)가 혼입된 PSC용 그라우트 몰탈의 강재부식성능을 평가하였다. 초단유리섬유를 함유한 배합이 PSC 그라우트 몰탈로서 소요성능을 만족시키는지를 확인하기 위하여 유하시간, 블리딩 및 압축강도를 측정하였다. 초단유리 섬유를 함유한 몰탈의 부식저항 성능은 염소이온 확산시험, 몰탈 흡수시험과 표면전기저항 측정 결과에 근거하여 수행되었다. 시험결과, 초단 유리가 혼입된 모든 배합은 OPC만 사용된 배합에 비하여 그라우트의 부식저항성능을 개선시키는 것으로 확인되었다. 다만, 초단유리섬유를 사용함으로서 유하시간은 단축되지만 블리딩이 발생하여 소요성능을 만족하지 못하는 것으로 확인되었다. 그러므로 PSC 그라우트에 적합한 초단유리섬유배합이 되기 위해서는 물-바인더비의 조정이 필요한 것으로 판단된다.

There is legal uncertainty and ambiguity with regards to the classification and disposal of sludge generated from glassetching process. Moreover, secondary effect on the environment such as corrosion of landfill construction by the sludgeproduced in glass etching process was observed in waste landfill site. As part of response to the parliament’s request forthe relevant data and local media coverage, exhaustive investigation of glass etching process was required. Accordingly,we conducted an exhaustive investigation of 8 glass etching manufacturers. Glass etching business is one of the businessesthat have seen rapid growth since 2010 with the development of semiconductor and electronics industry, and glass etchingproducers are mostly located in Gumi, Cheongju, Sejong, Gongju, and Cheonan cities. In this study, we investigated theharmful effects of wastes generated from the glass etching process, how those wastes are classified and treated, problemsarose from the process, and secondary effects on the environment observed in waste landfill site. The study found thatcyanide, lead, mercury, trichloroethene, and perchloroethene were not detected in the sludge produced from glass etchingprocess, and hexavalent chromium, copper, and arsenic were either not detected or reported at very low level, which wasbelow the threshold concentration level of designated waste. In contrast, pH of sludge produced from glass etching processwas between 1.7 and 2.3, pH of hydrofluoric acid used for glass etching showed acidic value of 1.5, which suggests thatthe classification system of such hazardous substance requires reconsideration.
