[연구목적] 본 연구는 현행 교양회계 교과과정을 교양교육적 측면에서 재검토하고 심층적으로 분석하여 문제점을 발견하고 이를 개선할 수 있는 구체적인 교과과정을 제시하였다. 본 연구의 주요한 목적은 교양회계의 교양교육적 의미를 재검토하고 향후 4차 산업혁명의 흐름에 대학이 능동적으로 대응하기 위한 교양교육을 재정립하는 데 있다. [연구방법] 현행 교양회계 교육과정이 지니는 문제점을 분석하기 위하여 교양회계 교재를 무작위로 선정하고 교재의 구성과 세부 내용을 실용적 측면과 자유교양적 측면에서 검토하였다. 그리고 발견된 문제점을 개선하는 설계원리를 제시하였고, 이에 기초한 개선된 교양회계 교과과정을 설계하는 방향으로 연구를 수행하였다. [연구결과] 연구결과 개선된 교양회계 교과과정은 기존의 회계원리 교재 목차에서 탈피하여 회계핵심원리를 기초로 구성하였다. 그리고 핵심원리에 인성원리를 결합한 교과과정을 설계하였다. [연구의 시사점] 현행 교양회계 교과과정을 구체적으로 분석하여 문제점과 구체적인 개선방안을 시도하였다는데 연구의 시사점이 있다. 특히 기존의 교양회계의 교과 구성에서 과감하게 벗어나 회계핵심원리 중심으로 새롭게 설계한 점은 중요한 의의를 가지는 것으로 판단된다. [Purpose] This study has reviewed the current liberal arts accounting curriculum in terms of liberal arts education and suggested a specific curriculum that can improve the problems found. The main purpose of this study is to rediscover the meaning of liberal arts education in liberal arts accounting and to build a curriculum for the university to actively respond to the 4th industrial revolution. [Methodology] In order to analyze the problems of current liberal arts accounting curriculum, liberal arts accounting materials were randomly selected and the composition and details of the textbooks were examined in terms of useful arts and liberal arts. In addition, we reviewed the design principles that can improve the problems found and presented a new liberal arts accounting curriculum. [Findings] As a result, the curriculum of the liberal arts accounting improved from the contents of the existing accounting principles textbooks and composed based on the key accounting principles. The curriculum combines the principles of personality with the key principles. [Implications] This study is meaningful in that it analyzes the current liberal arts curriculum in detail and finds problems and tries to improve them. In particular, the redesign of the liberal arts accounting process centered on the core principles of accounting seems to have a important significance.

Over 30% of domestic soil contamination has occurred via petroleum products and complex oil. Moreover, contamination by complex oil is more intense than it is by a single petroleum product species. In this study, we analyzed sectional TPH (total petroleum hydrocarbon) pattern and sectional ratio of current domestically distributed petroleum products, such as kerosene, diesel, bunker C, and lubricant and complex oils, to determine pollution characteristics of the soil. In the TPH pattern, kerosene, which is a light distillate, had an early retention time, and lubricant oil, which is a heavy distillate, had a late retention time in the gas chromatogram. In addition, we obtained a complexly contaminated soil via diesel and lubricant oil from the Navy and inspected it for its ratio of complex oil species. The inspection results showed that this soil was contaminated with 85% diesel and 15% lubricant oil. The method developed in this study could be used to determine complex petroleum sources and ratios at sites with accidentally contaminated soil.

It rains heavily, such as long rain and typhoons, during a typical rainy season in Korea. In this season, several fuel contamination accidents by water and vehicular problems caused by water contaminated fuel occur. Many research groups have studied the effects of water contaminated fuel on vehicles and environment. However the characteristics of water contaminated fuel have not been studied. In this study, we prepared diesel samples with a constant ratio of water (0~30 volume %) using an emulsifier. Then, we analyzed these diesel samples for their representative fuel properties. In the analytical results, diesel with 30% water showed an increase in fuel properties such as density (823→883 ㎏/㎥), kinematic viscosity (2.601→6.345 ㎟/s), flash point (47→56℃), pour point (-22→2℃), CFPP (cold filter plugging point) (-17→20℃) and copper corrosion number (1a→2a). The low temperature characteristics, such as low pour point and CFPP, blocks the fuel filter in the cold season. In addition, water contaminated diesel decreases lubricity (190→410 ㎛) under high frequency reciprocating rig (HFRR) and derived cetane number (54.81→34.25). The low lubricity of fuel causes vehicle problem such as pump and injector damage owing to severe friction. In addition, the low cetane diesel fuel increases exhaust gases such as NOx and particulate matters (PM) owing to incomplete combustion. This study can be used to identify the problems caused by water contamination to vehicle and fuel facilities.

The Study of Fuel Properties for Biodiesel Derived from Duck's Oil
임영관(Lim, Young-Kwan),이천호(Lee, Cheon-Ho),정충섭(Jung, Choong-Sub),임의순(Yim, Euisoon) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.11
Biodiesel was well known for eco-friendly alternative fuel for petrodiesel. But biodiesel have disadvantage such like it was derived from food resource which was high price. In this study, We synthesized the biodiesel from duck's oil which was food trash via transesterification under base catalyst. After analytic result of density, kinematic viscosity, cold temperature characteristics, lubricity and cetane number which were main fuel characteristics, this duck's biodiesel have enough to fuel specification for except of domestic winter season.
