  • Production of biodegradable polymer polyhydroxyalkanoates (PHAs) from industrial wastes exhibits several advantages such as recycle of waste and the production of high valuable products. To this end, this study aimed at isolating from the sewage treatment plant a PHA producing bacterium capable of utilizing wastes generated from biodiesel and food industries. A Bacillus cereus strain capable of producing poly(3-hydroxybutyrate) [P(3HB)] was isolated, which was followed by confirmation of P(3HB) accumulation by gas-chromatographic analyses. Then, the effects of nutrient limitation on P(3HB) production by B. cereus was first examined. Cells cultured in a minimal medium under the limitation of nitrogen, potassium and sulfur suggested that nitrogen limitation allows the highest P(3HB) accumulation. Next, production of P(3HB) was examined from both waste of biodiesel production (crude glycerol) and waste from food industry (spent coffee grounds). Cells cultured in nitrogen-limited minimal medium supplemented crude glycerol and waste spent coffee grounds extract accumulated P(3HB) to the contents of 2.4% and 1.0% of DCW. This is the first report demonstrating the capability of B. cereus to produce P(3HB) from waste raw materials such as crude glycerol and spent coffee grounds.

  • This study is an analysis of the life of Max Planck (1858-1947), the in view of engineering literacy education. Some expressions describing Planck include "the father of German science", "the namer of Quantum". Furthermore, he is the scientist who permanently engraved his name in a scientific invariant called the Planck Constant. Planck had already made remarkable scientific achievements in his mid-ages, which became the springboard of quantum mechanics, but he went on to achieve much more in his old age. Between 1910s and 1930s, he was the director of the Kaiser-Wilhelm Gesellschaft, the Berlin Academy, and the German Physics Society, which is the German core research group. In the 1910s, he endured the terrible personal suffering of losing his three children and then succeeded in rebuilding German science in the 1920s in his golden age of 70s. His achievement was great not only as a scientist but also as a science administrator. His life was contradictory in several ways. While fundamentally being a conservative, he initiated a great scientific revolution. While making efforts to preserve traditional values, he was in the center of great many upheavals and destruction. While being the incarnation of honesty, he was also given to extremely delicate political positions. In his long career, Planck lived with all his might as a leader of the German science organizations and permanently left his name on the institute representing Germany. Planck succeeded in his work for the institutional development of science, philosophical understanding of science, and as a role model of exemplary scientist. His long life was accompanied by both achievements and failures, intangible and difficult to judge. Today, as research and development management and scientific leadership have become increasingly important, Planck's life may be a good example of engineering literacy education.

  • This study attempted to test not only the influence of transformational leadership(TFL) on employees' unethical pro-organizational behavior(UPB), but also the mediating effect of organizational identification(OID) between TFL and employees' UPB. This study employed two research methods: literature review and empirical testing of the developed hypotheses. Data were collected through online questionnaire instruments from 229 employees working at companies in Korea. To test the hypotheses, structural equation modeling was employed. The model is shown as adequately fitting to the data. The results showed that there was not a positive and statistically significant relationship between TFL and employees' UPB, and OID played as a mediator in the relationship between TFL and employees' UPB. These findings provide a meaningful implication that the positive impact of TFL is linked to employees' UPB through OID.

  • Despite its remarkable socioeconomic development, South Korea underperforms in terms of female labor force participation and women in leadership positions. As women appear to avoid nuclear engineering, we aim to evaluate its relative performance in attracting women to its labor force compared to other college majors. Using college-major level information from 2000, we test whether the female faculty share in nuclear engineering is lower than its counterparts. Although nuclear engineering has one of the lowest female faculty shares, its share exceeds that of agricultural science, business and economics, chemical engineering, chemistry, civil engineering, and industrial engineering once we properly control for gender composition among students and other compounding factors. In other words, once female students major in nuclear engineering, they are less likely to leave their fields compared to their counterparts in other disciplines. This result implies that if the nuclear engineering field aims to attract more women to its workforce, it is important to target them from the early stage of their careers.

  • Before the financial crisis of 1997 in Korea, many industrial sectors across the country have achieved remarkable economic growth since the 1970s because of the development of large-scale equipment industries such as civil engineering, steel, construction and chemical industries. However, after the financial crisis, the economic growth rate has slowed down. Also, the global recession and the rise of China in the global business environment have led to a long-term recession in the national industry as a whole. In current economic environment, it is not easy for the companies even having excellent resources to continue its competitive advantage. Moreover, the chemical industry, which has an influence as a basic industry of other industries, misses the point of transformation into a high value-added industry, as shown in previous research. In order to meet the rapidly changing global business environment, Korean chemical companies should have a dynamic capabilities which to rapidly reallocate and consolidate the resources and capabilities they possess. The dynamic capabilities to convert, rearrange and develop the resources possessed by the company in the direction of creating high added value and to promptly search for, absorb, transform and fuse newly required capabilities and resources should be continuously applied to Korean chemical companies. It is the core competence to secure competitive advantage. In order to secure the dynamic capabilities of the company, the dynamic capabilities of individual employees should be strengthened and employees should be able to demonstrate their own leadership so that they can proactively work and self-manage in a positive direction. Previous studies have focused mainly on the dynamic capabilities of firms. However, the competence of the human resources that make up the enterprise leads to the capabilities of the enterprise, and the human resources themselves are also important corporate resources. This paper focuses on the dynamic capabilities of individuals and strives to clarify the causal relationship between dynamic capabilities, self-leadership, and organizational effectiveness which have direct or indirect effects on management outcome. The reasons for choosing the chemical industry are based on the fact that a domestic chemical companies are in a long-term recession, and they lacks a innovation and value creation capabilities. Also, chemical industry has a large impact on the national economy.
