  • The fruit and seeds of Butea monosperma (Lam) Kuntze (Fabaceae) are useful in piles, anthelmintic, eye diseases, and inflammation in the Indian system of medicine. Hence, we have evaluated the anti-inflammatory activity of the fixed oil, mixed fatty acids, and unsaponifiable matter of B. monosperma against carrageenan-induced paw oedema and cotton pellet-induced granuloma in rats. The fixed oil, mixed fatty acids, and unsaponifiable matter of the oil exhibited significant anti-inflammatory activity on the tested experimental animal models. The unsaponifiable matter of the oil produced higher protection compared to fixed oil and mixed fatty acids. Phytochemical analysis of the fixed oil revealed the presence of steroids and terpenoids while unsaponifiable matter of the oil showed the presence of ${\beta}-sitosterol$. Also, four fatty acids were identified in the fixed oil by gas liquid chromatography. The anti-inflammatory activity of the fixed oil may be due to unsaponifiable matter or combination of unsaponifiable matter and mixed fatty acids.

  • It's a tendency to strengthen related international laws as the importance on marine oil pollution recently becomes the issue. According to the regulation of IMO, oil discharge from ships is allowed under 15 ppm only and oil filtering equipment is essential. However, for large ships using heavy fuel oil of over S.G 0.98 and viscosity 380 cSt and system oil, it has been in difficulty to process with existing filtering type of oily water separator. Oily water pre-separator of laminated plate type which is one of gravity type separator has very simple structure and it also makes easier to maintain and repair. In another words, it fits well to process large amount of rich oil with high specific gravity. In this paper, oily water pre-separator of laminated plate type has been studied. The function of emulsified oil and 4 different types of oil have been analyzed and each character has been investigated and proved by experiments. As the result of it, the efficiency of separating oil water has been advanced by 10% in case equipped with pre-separator. In addition, the higher temperature is and the more laminated plate has, it turns out to be getting more effect.

  • A shell-and-tube oil cooler with plate fins was suggested to improve the defect of the conventional shell-and-tube oil cooler. Experiments were conducted to evaluate the heat transfer performance on the shell side of shell-and-plate finned tube oil cooler with three different tube numbers(9, 13 and 19). Oil flowing on the shell side was cooled by cold water flowing inside the tubes. A shell-and-tube heat exchanger of an oil cooler consisted of one shell pass and two tube passes with the inner tube diameter of 8.82 mm and the tube length of 575 mm. From the experiment of shell-and-tube oil cooler, it was found that the heat transfer coefficient of oil cooler with 9 tubes, as oil flow rate was increased, was approximately 140% and 250% higher than that of 13 and 19 tubes, respectively. The heat transfer coefficient at the water flow rate of $3m^3/h$, also was 120% and 140% higher than that of 2.4 and $1.8m^3/h$, respectively.

  • The present study analyzed and compared the mutual information obtained by stimulating saleswomen with 6 natural fragrances 100% basil oil, Lavender oil, lemon oil, jasmine oil, ylang-ylang oil (KIMEX Co., Ltd.), and skatole. When stimulated with basil and skatole, which were less favored fragrances, the women produced a greater amount of mutual information than when not stimulated with any fragrance. In addition, a comparison among the effects of the fragrances revealed that the subjects tended to produce more mutual information regarding less favored fragrances than regarding more favored ones. This is because the amount of mutual information in the cerebrum is linked to the women's preference regarding fragrances. Consequently, less favored fragrances have been demonstrated clearly to produce more mutual information among the subjects.

  • There has been no specific test available for identifying the sesame oil among common edible oils. As the contents of sesamin and the ratio of sterols allowed the estimation for the genuine sesame oil, the author investigated to establish some instrumental methods for verification of genuine sesame oil and its distribution in the market. The sesame oil was saponified and the sesamin and sterols were isolated from the unsaponiable fraction by Florisil column chromatography. The individual components were determined by gas- chromatography and sesamin standard (purified sesamin) was obtained by silicagel column chromatography. The gas- chromatographic condition using Flame Ionization Detector supported on 10% OV-101 with di-(2-ethylhexyl) sebacate as an internal standard was suitable, and quantitation of sesamin and sterols, including campesterol, stigmasterol and ${\beta}-sitosterol$ was carried out. The results of this study showed that contents of sesamin in genuine sesame oil were 0.3-0.5% and the ratio of stigmasterol to compesterol was 0.3-0.6 and ${\beta}-sitosterol$ to campesterol 3.0-3.8. The 50 samples from the markets in Seoul were composed of 70% genuine sesame oil, and others were mixed with palm oil, rape seed oil and soybean oil.

  • Many investments and works being continued to preserve green ocean in each countries of the world. Especial1y, the researches on the prevention of marine oil pollution being strengthened. It is not easy to disclose sludge oils that were produced necessarily in the ships operation, so that they are transferred to shore treating facility after collected inside the ship's sludge tank mostly. However, this shore transferring method is not only costly and time consuming but also entails risk of oil pollution. In this regard, it will be the best way to manage the sludge oils inside ship itself. The purpose of this study is to device an ultrasonic breaking systems which recycle the sludge oil from ships into usable oil to be burnt. In this paper, the first place, matrix structures of sludge fuel oil(SFO) and sludge lubricating oil(SLO) with the irradiation time for ultrasonic vibrator were interpreted. And, erosion damage for vibrator horn tip which is one of important part of ultrasonic breaking systems was examined under such an environment of the sludge oils. The material for horn tip is being made of SS41 steel and its erosion phase was investigated with variation of the vibration amplitude of 50${\mu}{\textrm}{m}$ and 24${\mu}{\textrm}{m}$ as well as the change of temperature in the oil environments. It is suggested that the experimental results can be helpful to the development of sludge oil disposing systems for the vessel.
