The purpose of this study is to investigate the current conditions of the domestic and foreign curricula in the field of chemical engineering and to draw implications. The results of the study are as follows. Most of the domestic research universities (including non-certified universities) have curricula organized within the scope of the ABEEK certification, which is the minimum standard guide for chemical engineering curricula. However, we are concerned that chemical engineering education in some domestic universities may lack in education quality and program relevance. Graduates from these universities may not have equivalent qualifications as international graduates. It is considered that most of the 12 domestic universities organize their subjects according to the certificate of accreditation standard and to the traditional subjects of chemistry in the 'Department of Chemical Engineering' or 'Department of Chemical and Biological Engineering Chemical and Biological Engineering'. However, due to the increase in the number of overlapping subjects with other majors because of the movement towards academic diversity, the integrity of the chemical engineering curricula is at risk. In addition, after surveying the major and research areas of the department professors, it has been found that there is a shortage of professors who have majored in chemical engineering. Therefore, there is a concern that students may lack understanding of the core principles of chemical engineering. The results of the analysis of the curricula of overseas research universities (including non-certified universities) are as follows. Although the chemical engineering industry in developed countries like the United States and Europe is advancing and changing very quickly, the chemical engineering education in these countries is highly focused on traditional subjects and other related subjects in order to cultivate traditionally trained chemical engineers. The Department of Chemical Engineering at overseas universities still maintains the academic integrity of the chemical engineering field. This is a significant suggestion for our country. On the other hand, domestic universities are changing the name of their chemical engineering major, or even if the name is maintained, they are fusing their curriculum with other majors such as material engineering. Therefore, it is very necessary at this point to start a discussion regarding the integrity of the department of chemical engineering in Korea. We hope that the departments of chemical engineering in domestic universities maintain the integrity of traditional chemical engineering while operating the curriculum within the scope of the standards of the engineering education certification system.

Faculty of engineering, Niigata University has been executing start-up engineering education programs for the first-year students to educate his or her ability to solve engineering problems. They are divided into teams and tackle a task that they expect to easily accomplish. The expected results are hardly obtained. Then they try to seek the gap between the results and their knowledge. They analyze the phenomena and improve the approach. They evaluate the results of second trial and the effectiveness of the measures. That is, the project requires so-called PDCA cycles for students to solve engineering problems. The start-up engineering project is one of the compulsory subjects and seven departments have given the students several tasks based on their technicality. The students exchange their knowledge, ideas and learn how to use knowledge to solve the problems. Their reports and questionnaire survey proved that the projects are highly effective to improve his or her ability to solve engineering problems and give them strong motivation to learn engineering. We introduce the some tasks and the outcomes of the projects set by seven departments; mechanical and production engineering, electrical and electronic engineering, information engineering, biocybernetics, chemistry and chemical engineering, civil engineering and architecture, and material science and engineering.

This study investigated various attributes that contributed to successful employment in order to develop employment support programs, especially for female engineering students. We surveyed engineering students who graduated between 2006 and 2011. The 401 employed graduates participated in an online survey. The surveys inquired about their attachment towards their major, participation in various academic and non-academic activities, and their participation's contribution to their successful employment. In regards to their majors, women, in general, had lower levels of satisfaction, confidence, attachment, and motivation to succeed in their fields when compared to their male counterparts. These results show that engineering colleges still need to work on empowering female engineering students to gain confidence in their engineering major and attachment. The graduate school experience was highly rated by both men and women, whereas double majors exhibited somewhat lower scores. Among academic activities, part-time work experience and major-related internships were rated as the most helpful, and among extracurricular activities, study-abroad for language training and participation in student council or clubs received high scores. There was little difference between men and women in study-abroad participation, and women participated more actively in student councils. However, women had much less major-related work experience, reaffirming that colleges need to expand internship and field experience programs for female students.

Abstract Glycolysis has a main function to provide ATP and precursor metabolites for biomass production. Although glycolysis is one of the most important pathways in cellular metabolism, the details of its regulation mechanism and regulating chemicals are not well known yet. The regulation of the glycolytic pathway is very robust to allow for large fluxes at almost constant metabolite levels in spite of changing environmental conditions and many reaction effectors like inhibitors, activating compounds, cofactors, and related metal ions. These changing environmental conditions and metabolic reaction effectors were focused on to understand their roles in the metabolic networks. In this study, we have investigated for construction of the regulatory map of the glycolytic metabolic network and tried to collect all the effectors as much as possible which might affect the glycolysis metabolic pathway. Using the results of this study, it is expected that a complex metabolic situation can be more precisely analyzed and simulated by using available programs and appropriate kinetic data.

Streptomyces venezuelae YJ028, bearing a deletion of the entire biosynthetic gene cluster encoding the pikromycin polyketide synthases and desosamine biosynthetic enzymes, was used as a bioconversion system for combinatorial biosynthesis of glycosylated derivatives of tylosin. Two engineered deoxysugar biosynthetic pathways for the biosynthesis of TDP-3-O-demethyl-D-chalcose or TDP-L-rhamnose in conjunction with the glycosyltransferaseauxiliary protein pair DesVII/DesVIII were expressed in a S. venezuelae YJ028 mutant strain. Supplementation of each mutant strain capable of producing TDP-3-O-demethyl-D-chalcose or TDP-L-rhamnose with tylosin aglycone tylactone resulted in the production of the 3-O-demethyl-D-chalcose, D-quinovose, or L-rhamnose-glycosylated tylactone.
