In recent years, many countries have invested enormous efforts to tackle increasingly harsh environmental problems, especially the greenhouse effect. The addition of biomass into coal is regarded as a promising technology to mitigate CO2 emissions. However, the costs related to retrofitting injection systems and unstable combustion inhibit this option. Therefore, this thesis developed a two-in-one fuel that impregnates molasses into the holes of low-rank coal(LRC), which can be directly applied...

영국은 2010년 보수당 정부가 출범한 이후 교원의 질적 제고를 위해 지속적인 교원양성체 제 개혁들을 추진해 왔다. 본 연구는 영국의 교원양성체제의 내용과 특징을 살펴보고 한국의 교원양성정책과 체제에 대한 시사점을 도출하고자 한다. 본 연구에서 분석한 영국의 교원양 성체제의 특징은 다음과 같다. 첫째, 영국의 교원양성체제는 다양한 양성 모델을 운영하고 있 지만 현장중심 교원양성 모델을 중심으로 단위학교와 양성기관 간의 긴밀한 협력 체제를 강 화하고 있다. 둘째, 교원양성 재구조화의 원리로서 영국은 교원양성경로의...

In recent years, a number of CEOs of big Korean conglomerates are being prisoned or sentenced longer period than ever before. Legally, since executive officer system was introduced, executive function of BOD has been separated and appeared to more focus on supervisory function. In addition, in terms of directors’ responsibility, legislative policies, which strengthen, alleviate or decrease that responsibility by taking account of the specialty of position of directors, have been considered....

Financial regulation can be referred to "an authority puts limit in certain activities and enforces compliance in order to maintain market order in trade among financial institutes, producers of financial products, and financial customers. Changes of financial regulation systems in Korea have been accelerated mainly by the foreign exchange crisis, the global financial crisis and FTA(Free Trade Agreement between Korea and Unites States of America, KORUS). Especially, ‘market regulation...

The paper aims to research kindergarten student teachers’ perceptions of reflective journal writing and its role in fieldwork placement within the context of Hong Kong. To respond to their professional growth, student teachers use reflective journal writing as an essential assignment in early childhood education because it gives them the opportunity to explore the understanding they have gained in a specific context of fieldwork placement practices. Nevertheless, the quality of reflection is...

본 연구는 남·북한의 보훈정책을 비교하기 위하여 다음과 같은 연구의 목적을 설정했다. 첫째, 남·북한의 보훈정책을 비교하기 위한 연구방법으로서 기존의 문헌의 접근방법에 대한 검토를 통해 내재적·외재적 접근방법을 통합하여 상징주의적 관점에 의한 분석방법의 유효성을 검증해보고자 했다. 둘째, 남·북한 보훈정책의 목적(이념)과 수단의 상징성을 분석하고자 한다. 즉 기존의 연구들이 상징성 또는 실질정책에 대한 소개에 근거하고 있다면 본 연구는 그러한 상징들이 사용되는 맥락을 분석하여 남·북한의 체제유지에...

drilled for the next 20 holes with the same drill bit. CFRP holes and CFRP-Ti stack holes were evaluated in terms of machined hole quality. The main tool wear mechanism of PCD drills is micro-fractures that occur when machining the Ti plate of the stack. Tool wear increases the instability and the operation temperature when machining the Ti plate. This results in high drilling forces, large hole diameter errors, high surface roughness, wider CFRP exit thermal damage, and taller exit Ti burrs.

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy...
