The study of bioproduct production, such as bioethanol and biochemicals, from inexpensive biomass has recently attracted considerable attention. Compared to land biomass, marine biomass can be grown rapidly and is easily cultivated without the need for expensive equipment. In addition, annual...

Crude canola oil (CCO) contains about 100–300ppm of phospholipids, which have shown negative effects on biodiesel/buffer solution phase separation, resulting in low biodiesel production yield. Therefore, phospholipids should be removed before transesterification by a degumming process for...

This study compares the efficacy of soaking and percolation pretreatments with alkaline solutions for lignocellulosic biomass. The pretreated biomasses underwent enzymatic hydrolysis. Various biomasses such as rice straw and barley were pretreated by soaking processes in various alkaline...

In this study, pre-biodiesel-production lipid extraction from microalgae (Chlorella vulgaris) was performed. The yield-enhancing effects of ionic liquid blends on the lipid extraction were investigated. The initial fatty acids content of the C. vulgaris was 292.2 mg/g cell. The lipid...

Red algal biomass is a promising alternative feedstock for bioethanol production, due to several advantages including high carbohydrate content, growth rate, ethanol yield, and CO2 fixation ability. However, it has been known that most yeast strains can not utilize galactose, the major sugar of...

Purpose The purpose of this paper is to identify the root cause of low yield problems in the semiconductor manufacturing process using sensor data continuously collected from manufacturing equipment and describe the process environment in the equipment. Design/methodology/approach This paper...

With the concept of “creative economy” emerging as a new paradigm of economic growth in Korea, the frequency of debates over related topics are being held, including the meaning and aims of the concept, as well as policy measures needed to realize it. While there is no consensus yet on the...

Citizens' economic perceptions can shape their political and economic behavior, making those perceptions' origins an important question. Research commonly posits that media coverage is a central source. Here, we test that prospect while considering the alternative hypothesis that media coverage...

Korean Abstract: 일본은 2013년 들어서부터 TPP, 일·EU FTA, RCEP, 한·중·일 FTA 등 메가 FTA 협상을 대대적으로 전개하고 있다. 한국이 이미 한·EU FTA와 한·미 FTA를 발효시킨 것에 비하면 일본의 미국, EU와의 FTA 체결은 늦는 대신 TPP...
