  • To prepare alkaline degreasing agents(SADAs), tetrasodium pyrophosphate(TSPP), $Na_2CO_3$, Tetronix T-701 (T-701), Na-dioctyl sulfosuccinate(303C), Demol C, and MJU-100A were blended. The prepared degreasing agents were tested with steel specimens and the results were as follows. The degreasing powers of SADA-6($Na_2CO_3$ 50g/TSPP 25g/T-701 10g/303C 15g/Demol C 12g/MJU-100A 8g/water 130g mixture) for press-rust preventing oil were 98% and 99% degreasing at 4wt%, 70 $^{\circ}C$ and 90 $^{\circ}C$, respectively; for quenching oil, the degreasing power of SADA-6 was 92% degreasing at 4wt% and 70 $^{\circ}C$. From these results, it was proved that the SADA-6 exhibits a good degreasing power. Foam heights measured immediately after foaming by Ross & Miles method and Ross & Clark method at 6wt% and 60 $^{\circ}C$ were 16mm and 40mm, respectively. SADA-6 was proved a good low foaming degreasing agent.

  • Hasāh al-kuliya (Nephrolithiasis) is a common disease with a worldwide prevalence of about 12%. A 64 years old male patient, who visited the outpatient department of National Research Institute of Unani Medicine for Skin Disorder (NRIUMSD), Hyderabad, presented with complaints of mild dull pain in right flank region and burning micturition for one month. The ultrasonography of whole abdomen confirmed that there was one stone of 5 mm in calyceal region of each kidney. The patient was treated with the Unani regimen comprising of three formulations Majoon, Hajrul Yahood (5 gm), Jawarish Zarooni Sada (5 gm) and Habb-i-Mudir (1000 mg) for 6 months. The patient did not report any acute pain during the therapy. After 6 months of treatment the ultrasonography of whole abdomen showed absence of the stone from each kidney, ureters and bladder. There was no recurrence of the disease during next 6 months of post treatment follow up. This case report documented the successful medical treatment and prevention of recurrence of bilateral nephrolithiasis through Unani medicines. It concluded that the Unani regimen was effective and safe in the management of bilateral nephrolithiasis.

  • The dinoflagellate Alexandrium tamiyavanichii Balech, a producer of toxins causing paralytic shellfish poisoning (PSP), has recently been considered as one of main organisms responsible for toxication of shellfish in Japan. In this study, A. tamiyavanichii was subjected to a molecular phylogenetic analysis inferred from 28S rDNA D1-D2 sequences and a species-specific LSU rRNA-targeted oligonucleotide DNA probe was designed to identify A. tamiyavanichii using the whole cell-FISH (fluorescence in situ hybridization). The sequences of the 28S rDNA D1-D2 region of A. tamiyavanichii showed no difference from A. cohorticular AF1746l4 (present name A. tamiyavanichii) and formed a distinct clade from the 'tamarensis species complex'. The probe, TAMID2, reacted specifically with A. tamiyavanichii cultured cells, without any cross-reaction with other species belonging to the same genus, including A. tamarense, A. catenella, A. affine, A. fraterculus, A. insuetum and A. pseudogonyaulax. In a test of cross-reactivity with a field sample, TAMID2 reacted consistently with only A. tamiyavanichii, indicating that the present protocol involving the TAMID2 probe might be useful for detecting toxic A. tamiyavanichii in a simple and rapid manner.

  • Candida utilis can assimilate fatty acids, so it was hypothesized that the treatment of rice by Candida utilis would improve feed quality by reducing fat content and adding the yeast function that would stimulate rumen microbes. In this study, the oil assimilation ability of Candida utilis IFO1086, 0988, 0626 and the effect of treatment of Candida utilis IFO1086, IFO0626 on the nutrient contents of rice bran were examined. The effect of Candida utilis addition on the in vitro degradability of forage was also investigated. It was found that the oil assimilating ability of IFO1086 and IFO0626 was significantly (p<0.01) higher than that of IFO0988. Candida utilis treatment reduced the EE content and increased the CP, ADF and NDF percentage. The absolute amount of ether extract was decreased by 35.9% in IFO1086 and IFO0626 treatment. The absolute amount of crude protein was not changed by yeast treatment. The ADF and NDF amounts were increased. The addition of Candida utilis increased in vitro forage degradability significantly (p<0.05). Based on these results it can be postulated that treatment of rice bran by Candida utilis may improve feed quality by reducing fat content, increasing the CP content and adding the function of yeast for stimulating rumen microbes.

  • Silage is a major component of cattle rations, so the improvement of silage quality by the inoculation of lactic acid bacteria is of great interest. In this study, commercially distributed Lactobacillus plantram and Lactobacillus rhamnousas NGRI 0110 were used for ensilaging of guinea grass. The four treatments used were a control silage, a silage with cellulase addition, a silage with cellulose+L. plantram addition, and a silage with cellulose + NGRI 0110 addition. Silage quality, voluntary intake, nutrient digestibility, and the characteristics of ruminal fluid of wethers were investigated. Silage to which lactic acid bacteria were added showed low pH and acetic acid concentration and the highest lactic acid content. Dry matter and organic matter digestibility were significantly (p<0.05) increased by cellulase addition and significantly (p<0.05) higher values were observed in L. plantram- and NGRI 0110-added silage. Voluntary intake of NGRI 0110-added silage was the highest and that of control silage was the lowest. We concluded that the observed ability of NGRI 0110 to tolerate low pH and to continue lactic acid fermentation in high lactic acid concentration had also occurred in actual ensilaging. The results indicate that the addition of lactic acid bacteria might improve silage quality and increase digestibility and voluntary intake. The potential for improvement by NGRI 0110 was higher than that to be gained by the use of commercially available lactic acid bacteria.

  • A numerical simulation method has been developed to predict atmospheric flow and stack gas diffusion using a calculation domain of several km around a stack under complex terrain conditions containing buildings. The turbulence closure technique using a modified k-$\varepsilon$-type model under a non hydrostatic assumption was used for the flow calculation, and some of the calculation grids near the ground were treated as buildings using a terrain-following coordinate system. Stack gas diffusion was predicted using the Lagrangian particle model, that is, the stack gas was represented by the trajectories of released particles. The numerical model was applied separately to the flow and stack gas diffusion around a cubical building and to a two-dimensional ridge in this study, before being applied to an actual terrain containing buildings in our next study. The calculated flow and stack gas diffusion results were compared with those obtained by wind tunnel experiments, and the features of flow and stack gas diffusion, such as the increase in turbulent kinetic energy and the plume spreads of the stack gas behind the building and ridge, were reproduced by both calculations and wind tunnel experiments. Furthermore, the calculated profiles of the mean velocity, turbulent kinetic energy and concentration of the stack gas around the cubical building and the ridge showed good agreement with those of wind tunnel experiments.

  • 가무를 동반한 제사예능을 일본에서는 흔히 가구라(神樂)라고 부른다. 가구라의 어원은 가무쿠라(神座)라고 하여 신이 거하는 장소를 표현하는 것으로 제장 그 자체를 의미 한다. 그러나 현재에는 그 의미가 넓어져서 신이 거하는 자리를 마련해 놓고 마을 사람들이 한데 모여 그 앞에서 행하는 제사의 일체를 지칭하게 되었다. 본 논문은 일본의 미야자키현(宮崎縣) 북서부에 위치한 신화의 고장 다카치호(高天穗)에서 행해지고 있는 가구라를 현지조사를 통하여 작성한 것이다. 매년 벼 베기가 끝난 11월 말에서 이듬해 2월초에 걸쳐서 다카치호의 각 마을에서는 가구라가 행해진다. 일반 민가를 택하여 가구라를 연행하는 가구라야도(神樂宿)로 삼고서 밤을 새워 33번의 가구라가 봉납된다. 다카치호의 가구라는 주로 철야로 행해진다고 하여 요가구라(夜神樂)라고도 한다. 가무를 담당하고 있는 호샤동이라고 불리우는 사람들은 지극히 평범한 마을 사람들로 이들에 의해 다카치호가구라는 전승되고 있다. 다카치호가구라는 현재 20여개 마을에서 행해지고 있으며 국가지정 중요무형민속문화재로도 지정되어 있다. 다카치호가구라는 지금의 히로시마현의 동부인 이즈모의 사다대사(佐陀大社)에서 행해진 신사(神事)에 그 모범을 두고 있어서, 모리모노(採物)라고 총칭되는 사카키(柳), 고헤이(御幣), 방울(鈴), 부채(扇), 칼(太刀) 등의 무구를 들고 추는 춤이 주를 이루고 있으며, 여기에 신노(神能)라고 하는 가면놀이가 곁들어져 있다. 마을의 신사에서 수호신인 우지가미(氏神)와 야오요로즈노가미(八百万神)라고 해서 팔백만의 제신들을 맞이하여 가구라야도에 모셔놓고 순번에 따라 33번의 가구라를 연행한다. 히코마이(彦舞) 다이도노(大殿) 가미오로시(神降) 등 강신을 위한 춤으로부터 시작하여, 아마노이와토라고 하는 일본신화를 소재로 한 다지카라오(手力男) 우즈메(細女) 도토리(戶取)를 중심으로, 고풍(古風)의 귀신의 춤인 시바히키(紫引), 곡예가 혼합된 야츠바치(八鉢) 등이 있으며, 히노마에(日之前) 구리오로시(繰下) 구모오로시(雲下) 등의 송신(送神)을 위한 춤을 마지막으로 밤을 지새우며 아침까지 연행된 33번의 가구라가 끝이 난다. 본 논문에서는 다카치호가구라(高千穗神樂)를 민족지적 기술과 함께 예능론적 측면에서 살펴보았다. 다카치호가구라는 강신이나 신탁은 일어나고 있지 않으나 민가에서 행해지고 있는 가구라로서 사토가구라(鄕紳樂)의 고형을 유지하고 있다. 특히 다카치호는 천손강림의 땅으로 일본신화와 관련된 제차가 많은 부분을 차지하고 있으며 비교적 예능화가 진전되어 있다. 현지조사는 1997년 12월 6일부터 12일까지 이와토지구(岩戶地區)의 고카무라(五村)와 미타이지구(三田井地區)의 아사카베(淺部)에서 행하였으며 1999년 12월 17일부터 19일까지 그리고 2000년 12월 1일부터 10일까지 사바지역과 함게 아사카베에서 보충조사를 실시하였다.
