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.

바이오플라스틱은 탄소중립적이며 생분해가 가능하다는 점에서 기존 플라스틱의 대체재로 주목받고 있다. 이 연구는 일국 축차동태 연산가능일반균형 모형을 사용하여 석유 기반 플라스틱산업 규제와 바이오플라스틱산업 육성에 따른 경제적 환경적 파급효과를 추정하였다. 분석결과, 플라스틱산업 규제 시 온실가스 감축과 폐기물 감소 효과가 나타나 긍정적인 환경적 파급효과가 발생한 반면, GDP는 감소하여 경제적으로는 부정적인 파급효과를 확인할 수 있었다. 한편 플라스틱산업 규제와 바이오플라스틱산업 육성이 동시에 이루어지는 경우, 플라스틱 산업 규제만 시행하는 시나리오와 비교하여 유사한 수준의 온실가스 감축과 폐기물 감소효과가 발생했으나 바이오플라스틱산업 생산 확대가 기존의 경제적 손실을 상쇄시켜 GDP를 증가시키는 것으로 나타났다. 따라서 바이오플라스틱 생산 확대를 통해 석유 기반 플라스틱을 대체해 나간다면 온실가스 배출 및 플라스틱 폐기물 발생과 같은 환경문제를 개선하면서 경제성장을 가능하게 하는 탈동조화(decoupling)에 기여할 수 있을 것으로 판단한다.
