The aim of the Department of Chemistry is to have major scientific achievements and to teach chemistry majoring students. The students shall be highly qualified so that after graduation they would be experts for their future work and contribute to the local society and the country by developing cutting-edge scientific methods and source technologies for industry. The undergraduate program of the Department of Chemistry was established in September 1948. The M.Sc. program and the Ph.D. program were established in 1954 and 1963 respectively. In 1993, both the undergraduate and the graduate programs of the Department of Chemistry of Pusan National University were recognized as outstanding among the 64 chemistry departments in the whole country by the Korean Council for University Education. The Department is proud to be one of the leading chemistry departments among the universities outside of Seoul, the capital of this country. In addition, the Functional Substance and Chemicals Research Center organized within the Department of in 1998, the New Concept Bio·Physio Sensor Technology Research Center in 2002, and the Plastic Information Materials Research Center in 2003 have considerably promoted the University’s research collaborated with industry, and research institutes in Busan and South Gyeongsang area. A task force on the Functional Material and Chemicals, which is part of the Brain Korea 21 Project designated by the Korean government in 2006, and the Department is engaged in pragmatic education and research activities linked with new technologies such as nano technology, information technology, bio technology, and environmental technology. The study of Chemistry is divided into the five fields of Physical Chemistry, Organic Chemistry, Inorganic Chemistry, Analytical Chemistry, and Biochemistry. Students learn general chemistry, which encompasses all five fields and other individual areas of study through experiments and lectures. Physical Chemistry is the basis of chemistry, and it deals with the relation between heat and energy, reaction velocity and equilibrium and changes of chemical substances. As such, the study of physical chemistry is essential in all areas that involve chemistry. Organic Chemistry deals with the properties, synthesis, structure, and reaction of organic compounds, and plays a considerable role in almost all aspects of the phenomenon of life and our modern existence. It is an essential field in Semiconductors, Electronic Materials Chemistry, Nano Chemistry, Polymer Chemistry, Pharmacology, Medical Science, Molecular Biology, and Food Science. Inorganic Chemistry deals with the structures, properties, characteristics, and reaction of inorganic compounds related to metals. The study of inorganic chemistry is essential in Solid State Physics and Material Engineering. Analytical Chemistry deals with basic principles for the quantitative and qualitative analysis of substances, the methods of analysis, and the principles and application methods of analysis equipment. The study of analytical chemistry is essential in all areas requiring analysis, particularly for those who wish to major in Environmental Engineering, Atmospheric Science, Food Science, Geology, and Marine Science. Biochemistry is a field that attempts to understand the phenomenon of life at a molecular level. It deals with the characteristics and structure of substances that are closely related to the living body, and with the reaction of the body to these substances. The study of Biochemistry is essential for those who wish to major in Biology, Molecular Biology, Genetic Engineering, and Food Science.
