This work was done to investigate problems of cashew coating in a wooden-art industry such as ritual vessels and to improve a curing property of cashew film. The main problem in the cashew coating industry was a small-scale business, insufficiency of facilities, lack of knowledge about cashew resin and painting, and lack of a technology of productivity improvement by accelerated drying time of cashew film. In present, cashew coating for ritual vessels mostly used the petroleum as a thinner. The time of set to touch of cashew film thinning with petroleum on glass plates was increased with the increasement of the thinning proportion, but retarded from 3 to 11 times compared to that of an exclusive thinner according to thinning level. The addition of 20% aceton to petroleum contributed to the high reduction rate up to about 60% at the thinning level of 100%, which was effective to accelerate the drying time of cashew film. Even though only the petroleum or the petroleum-aceton(20%) mixture was used as a thinner, it did not exhibit any distinguishable differences in crack and appearance of cashew-film coated on Frexinus rhynchophylla after 5 cycles of soak under the vacuum-drying treatment.

Purpose - objective of this research is to investigate individual, organizational and environmental factors influence tacit knowledge sharing among healthcare professionals. The transmission of Tacit Knowledge is crucial for organizations to ensure that TK will be passed throughout organization, rather than stored in single employee. Research design, data, and methodology - In this study investigate organizational, individual and environmental factors that influence on TK sharing. To test hypothesizes, the survey method was chosen. Sample size was 100 but 74% of questioners returned. Results - The main findings of this research are related to influence of personal, social cultural and behavioral factors on tacit knowledge sharing. According to extracted data all factors have influence on tacit knowledge sharing except Emotional stability that was found to be negatively related to tacit knowledge sharing. That may means anxiety and stress level of workplace applies negative enhance on tacit knowledge sharing. And finally results show that social environment, team oriented culture and organizational commitment have strongest influences on tacit knowledge sharing. Conclusion - the findings of this study shows that personal, social cultural and behavioral factors influence on tacit knowledge sharing. And also indicates that, social and organizational factors enhance strongly on tacit knowledge sharing.

The installation of light oil facilities or delayed cokers seems to be inevitable in the oil refinery industry due to the heavy crude oil reserves and the increased use of light fuels as petroleum products. Petroleum coke is a byproduct of oil refineries and it has higher fixed carbon content, higher calorific value, and lower ash content than coal. However, its sulfur content and heavy metal content are higher than coal. In spite of disadvantages, petroleum coke might be one of promising resources due to gasification processes. The gasification of petroleum coke can improve economic value of oil refinery industries by handling cheap, toxic wastes in an environment-friendly way. In this study, $CO_2$ gasification reaction kinetics of petroleum coke, various coals and mixing coal with petroleum coke have investigated and been compared by using TGA. The kinetics of $CO_2$ gasification has been performed with petroleum coke, 3 kinds of bituminous coal [BENGALLA, White Haven, TALDINSKY], and 3 kinds of sub-bituminous coal [KPU, LG, MSJ] at various temperature[$1100-1400^{\circ}C$].

Petroleum industry produces one of the popular hazardous waste known as Petroleum Sludge. The treatment and disposal of petroleum sludge has created a major challenge in recent years. This review provides insights into various approaches involved in the treatment, and disposal of petroleum sludge. Various methods used in the treatment and disposal of petroleum sludge such as incineration, stabilization/solidification, oxidation, and bio-degradation are explained fully and other techniques utilized in oil recovery from petroleum sludge such as solvent extraction, centrifugation, surfactant EOR, freeze/thaw, pyrolysis, microwave irradiation, electro-kinetic method, ultrasonic irradiation and froth flotation were discussed. The pros and cons of these methods were critically considered and a recommendation for economically useful alternatives to disposal of this unfriendly material was presented.

Bioplastics are attracting attention as a substitute for conventional petroleum-based plastics because they are carbon neutral and can be biodegradable. This study estimated economic and environmental impact of regulating the petroleum-based plastics industry and fostering the bioplastics industry using a Recursive Dynamic CGE Model of the Korean Economy. Results show that the regulation of the conventional plastics industry exhibits a positive environmental impact by reducing greenhouse gases and plastic waste and a negative economic impact with a decrease in GDP. Meanwhile, fostering the bioplastics industry with regulation on conventional plastics industry has similar levels of greenhouse gas and waste reduction effects when there is only regulation on the conventional plastics industry. It is also shown that expanding the production of bioplastics industry offsets existing economic losses as a form of increased GDP. If petroleum-based plastics are replaced through the expansion of bioplastics production, it can contribute to the decoupling of greenhouse gas emissions and plastic waste from economic growth.

General aspects of deepwater petroleum exploration and production were identified and related technical challenges were addressed. Historical perspectives, insight, processes, and engineering applications are reviewed to enhance the design capability of the domestic offshore industry. The technical challenges and unique aspects of deepwater exploration and production were identified. The assessment of deepwater exploration, drilling, and production systems is a key stage for performing the front end engineering design (FEED). The global trends in deepwater development, including the feasibility for Korea, were reviewed.
