본 연구에서는 일상생활에서 에너지 용어가 사용되는 맥락을 알아보기 위하여 온라인 과학 기사를 수집하여 언어 네트워크, 토픽 모델링 분석 기법을 활용해 에너지 관련 기사에 사용된 용어의 빈도, 용어 네트워크, 기사의 주제를 분석하였다. 분석에 사용된 자료는 2018.3.1.부터 1년간의 온라인 과학 분야의 기사 중 에너지를 검색어로 하여 10개의 국내 중앙지에서 검색 및 선정된 2,171편이다. 이 기사들을 자연어 처리하여 51,224개의 문장과 507,901개의 단어로 데이터를 구성하였다. R 프로그램을 활용하여 용어 빈도수 분석 및 언어 네트워크 분석을 실시하였고, 에너지 용어 사용의 맥락 탐색을 위해 구조적 토픽 모델링 분석을 적용해 기사의 주제를 도출하였다. 기사에 사용된 용어 중 빈도수가 유난히 높은 용어는 기술, 연구, 개발로 새로운 소식을 알리는 기사의 특성을 반영한 것으로 나타났다. 한편, 기사 2편당 한 번 이상의 빈도로 사용되는 용어에는 산업 관련 용어(산업, 제품, 시스템, 생산, 시장)와 '전기', '환경'과 같이 에너지 관련 용어로 충분히 기대되는 용어들이 있었다. 한편, 에너지 관련 과학 수업에서 자주 사용되는 '태양', '열', '온도', '발전'도 빈도수 상위에 속하는 용어로 드러났다. 용어 네트워크 분석에서는 산업 및 기술과 관련된 용어와 기초과학 및 연구 관련 용어들이 약한 강도이지만 서로 군집을 이루는 것을 확인하였다. 한편, 에너지와 쌍을 이루는 용어의 분석에서는 '에너지 효율'을 비롯해 '에너지 절감', '에너지 소비' 등과 같이 에너지의 사용에 관한 용어들이 다수를 이루고 그 사용 빈도가 가장 높았다. 에너지 용어가 사용되는 맥락은 16개의 주제를 분류한 4가지 영역으로 '첨단산업', '산업', '기초과학', '환경 및 건강'으로 나타났다. 에너지 사용 관련 용어가 상당히 많이 사용된다는 결과는 에너지 수업의 시작점으로 에너지 저급화 개념의 도입이 효과적일 수 있음을 시사한다. 또한, 첨단산업이나 환경 및 건강의 맥락을 에너지 학습에 도입할 필요성도 보여준다. 본 연구에서 드러난 16개 주제에서 보이는 다양한 에너지 용어가 사용되는 맥락을 재구성해 에너지 관련 수업에 활용한다면 학생들이 학교에서의 에너지 학습과 일상적 상황을 통합적으로 인식하는 데 도움이 될 것이다.

Since 1973, the competition on the development of fuel saving type internal combustion engines has become severe by the two times oil shock, and new type engines are reported every several months. Whenever these new type engines are developed, new designs are required and they will be offered in the market after performing the endurance test for a long time. But the engine market is faced with a heavy burden of finance, as the developing of a new engine requires tremendous expenses. For this reason, the computer simulation method has been lately developed to cope with it. The computer simulation method can be available to perform the reasonable research works by the theoretical analysis before carrying out practical experiments. With these processes, the developing expenses are cut down and the period of development is curtailed. The object of this study is the development of simulation computer program for the small naturally aspirated four-stroke diesel engine which is intended to product by the original design of our country. The process of simulation is firstly investigated for the ideal engine cycle, and secondly for the real engine cycle. In the ideal engine cycle, each step of the cycle is simulated by the energy balance according to the first law of thermodynamics, and then the engine performance is calculated. In the real cycle imulation program, the injection rate, the preparation rate and the combustion rate of fuel and the heat transfer through the wall of combustion chamber are considered. In this case, the injection rate is supposed as constant through the crank angle interval of injection and the combustion rate is calculated by the Whitehouse-Way equation and the heat transfer is calculated by the Annand's equation. The simulated values are compared with measured values of the YANMAR NS90(C) engine and Mitsubishi 4D30 engine, and the following conclusions are drawn. 1. The heat loss by the exhaust gas is well agree with each other in the lower load, but the measured value is greater than the calculated value in the higher load. The maximum error rate is about 15% in the full load. 2. The calculated quantity of heat transfer to the cooling water is greater than the measured value. The maximum error rate is about 11.8%. 3. The mean effective pressure, the fuel consumption, the power and the torque are well agree with each other. The maximum error is occurred in the fuel consumption, and its error rate is about 7%. From the above remarks, it may be concluded that the prediction of the engine performance is possibly by using the developed program, although the program needs to reform by adding the simulation of intake and exhaust process and assumping more reliable mechanical efficiency, volumetric efficiency, preparation rate and combustion rate.

순환골재는 건설폐기물을 재활용함으로써 자원절약 및 대체자원의 개발과 환경보호의 측면에서 국가 사회적으로 많은 이점을 가지고 있다. 하지만 낮은 밀도와 높은 흡수율을 가지는 저품질 순환골재는 구조용 콘크리트 골재로 사용되지 못하고 주로 저부가가치로 사용되고 있다. 따라서, 이를 위하여 폐콘크리트 파 분쇄 후 발생되는 순환골재의 재료적 특성을 규명하기 위하여 물리적인 주요성질인 시멘트함유량, 절대건조밀도, 흡수율, 등을 검토하고, 2차 제품 생산을 위한 배합설계(안)을 도출하여 이를 적용한 배합으로 생산된 시제품의 휨 강도, 흡수율, 동결 융해 후 휨 강도, 압축강도, 기건비중 등에 대한 성능평가를 실시하여 품질기준 GR규격과 비교 검토 하였다. 실헌결과 순환골재 대체율 50~90%로 증가함에 따라 GR F 4007의 성능기준 보다 우수한 품질로 나타났으며, 순환골재를 사용한 콘크리트 2차 제품의 제조 및 활용할 수 있는 소정의 물리적 특성을 확보함에 따라 각종 건설공사에서 다양하게 사용이 가능 할 것으로 판단된다.

Companies build the factory automation system to improve management effectiveness and productivity as prime strategies for sustainable growth. But most companies undergo various trials and errors while carrying out the project without elaborate preparation stage for factory automation. In this study, we tried to verify what factors are critical to effectively building distribution automation system, which is a branch of factory automation system. A consulting model for setting up a Material Handling Automation System by utilizing the Stage-Gate Process, which is product development process was studied. 29 material handling automation projects carried out between the year 1990 to 2013 at K-Company were selected. Interviews with the project managers, operators and maintenance personnels, various records and current status of the projects were used as data for structural equations based on the Milan consulting model and existing researches of factory automation, CIM for material handling automation. Creating effective basis of production, material handling system and energy saving system with expert review, when preparing a material handling automation project, help promote the project planning thus contributing to the performance of the resulting system, which appears though rather weakly in our data. Also the effect of material handling automation can be enhanced through sufficient and effective links to the relevant environments such as production logistics management and automated warehouses. More detailed planning characteristics of project promotion or some time-series data of effective Material Handling Automation System could enhace furthur studies. We propose a consulting model for setting up an efficient material handling automation system.
