To evaluate the effect of dopaminergic activity on aldosterone secretion, the plasma renin activity, serum cortisol and aldosterone were measured by radioimmunoassay in 6 normal controls and 12 patients who had hyponatremia and generalized edema or ascites with possible condition with secondary aldosteronism before and after(15, 30, and 60 min) 15 mg of metoclopramide by iv bolus injection and same method with 500 mg of L-dopa by per oral in 6 normal controls and 12 patients with edema ascites. The result were as follows; 1) The basal level of PRA was higher in patients rather than normal controls but PRA was not influenced by MC or L-dopa administration on both normal controls and patients group. 2) The serum cortisol level was significantly elevated at 30 min after MC injection compared with basal level in normal controls but no significant change was noted in patients group. After L-dopa administration the serum cortisol level was not changed in both normal controls and patients group. 3) The serum aldosterone level was significantly elevated in 15, 30 and 60 min after MC injection in normal controls, and there also same tendency of aldosterone secretion was noticed in patients group. On the other hands, there was no changes in aldosterone level in both normal controls and patients group with L-dopa administration. Above result means that MC stimulate aldosterone secretion by dopaminergic antagonist and aldosterone secretion in normal subject is controlled by maximal tonic dopaminergic inhibition. In edematous patients, however, both of the dopaminergic inhibitory and stimulating effect of PRA, ACTH etc on the aldosterone secretion seems to be variable.

The purpose of this study is to investigate the perspective of pre-service chemistry teachers on the learning situations of visually impaired students through scientific inquiry in a darkroom and to propose a teaching and learning method for students with visual impairments. Twenty-one pre-service chemistry teachers from college of education in Gyeongbuk were encouraged to explore individually hands-on model for the molecular structure of ice freely, and had a discussion with a one of the researchers during the activity. All the conversation and discussion were audio-taped and transcribed for analysis. As a result, pre-service chemistry teachers realized that learning situation of the visually impaired students was quite different with their perception while exploring and figuring out hands-on model of the molecular structure of ice in the darkroom. They already learned and could see this model by themselves but also recognized that visually impaired students had inconvenience and difficulty in learning science concepts. Based on these reflections, some pre-service chemistry teachers suggested directions for modification to fit visually impaired students' needs more.

Pt-Ru and Pt-Ni bimetallic catalysts were prepared and tested for heavy hydrocarbon reforming. Metals were supported on CGO($Ce_{0.8}Gd_{0.2}O_{2.0-x}$) by incipient wetness method. The prepared catalysts were characterized by Temperature programmed reduction(TPR). Oxidative steam reforming of n-dodecane was conducted to compare the activity of the catalysts. The reforming temperature was varied from $500^{\circ}C$ to $800^{\circ}C$ at fixed $O_2$/C of 0.3, $H_2O$/C of 3.0 and GHSV of 5,000/h.Reduction peaks of metal oxide, surface CGO and bulk CGO were detected. Reduction temperature of metal oxide decreased over the bi-metallic catalysts. It is considered that interaction between metals leads to decrease interaction between metal and oxygen. On the other hands, reduction temperatures of surface CGO were dectected in the order of Pt-Ru > Pt-Ni > Pt. low reduction temperatures of surface CGO indicates the low activation energy for oxygen ion conduction to metal. Oxygen ion conduction is known as de-coking mechanism of ionic conducting supports such as CGO. In activity test, fuel conversion was in the same order of Pt-Ru > Pt-Ni > Pt. Especially, 100% of fuel conversion was obtained over Pt-Ru catalysts at $500^{\circ}C$.

The Jeungsan(1871-1909)'s revelation is the important meaning. Jeungsan hands down the two revelation for solution of Chosun postscript problem and presentation of Utopia. One time Suwun(1824~1864) is handed down and afterwords Jeongsan(1895-1958) after Jeungsan's Hwachon at 1917. Two revelations accomplish the day of the Jeungsan in public but the character is the countenance. The Jeungsan's revelation to Suwun solves present generation problems, the Jeungsan revelation to Jeongsan is continuously to do the day of the Jeungsan even after Hwachon. The Jeungsan stepped on the failure of the Donghak and on the upper lifestyle with the Cham-Donghag it opened the different side. The Cham-Donghag is concerned about the future Chosun to be the first-class country and Chosun Haewon is related with Danju Haewon. Danju Haewon is to be a fifty years religous study of Jeongsan. The Jeungsan's Gangse is to accomplish the Sungsajaein and it actualizes the appearance of Dotonggunja. Jeongsan is trying to do the religious activity about Sungsajaein and Dotonggunja as the Daedumok. The Jeungsan starts from revelation to the Suwun, to accomplish thought of the Cham-Donghag after Hwachon. The Jeungsan continuously has handed revelation led from religion activity, let Jeongsan do fifty years religious study. In the long run, it completes the fact that it accomplishes the outer space and the Chosun society of new setup, and a sacred religious work has been arranged the advocate of the Cham-Donghag through the Jeongsan by Woodang(1917-1996)'s Daesoonjinrihoe(1969).

A glutathione S-transferase (GST) related to the phi (F) class of enzymes only found in plants has been cloned from the Oryza sativa. The GST cDNA was cloned by PCR using oligonucleotide primers based on the OsGSTF5 (GenBank Accession No. $\underline{AF309382}$) sequences. The cDNA was composed of a 669-bp open reading frame encoding for 223 amino acids. The deduced peptide of this gene shared on overall identity of 75% with other known phi class GST sequences. On the other hands, the OsGSTF5 sequence showed only 34% identity with the sequence of the OsGSTF3 cloned by our previous study (Cho et al., 2005). This gene was expressed in Escherichia coli with the pET vector system and the gene product was purified to homogeneity by GSH-Sepharose affinity column chromatography. The expressed OsGSTF5 formed a homo-dimer composed of 28 kDa subunit and its pI value was approximately 7.8. The expressed OsGSTF5 displayed glutathione conjugation activity toward 1-chloro-2,4-dinitrobenzene and 1,2-epoxy-3-(p-nitrophenoxy)propane and glutathione peroxidase activity toward cumene hydroperoxide. The OsGSTF5 also had high activities towards the herbicides alachlor, atrazine and metolachlor. The OsGSTF5 was highly sensitive to inhibition by S-hexylGSH, benastatin A and hematin. We propose from these results that the expressed OsGSTF5 is a phi class GST and appears to play a role in the conjugation of herbicide and GPOX activity.

It was revealed that leaching of elements were partly inhibited because seawater contains plenty of dissolved ions than fresh water. On the other hands, the low activity coefficient and the formation of complex with chloride and sulfate play roles in enhancing element leachability. However, the pH buffaring capacity of seawater is the most important factor that makes the leaching of elements and its chemical behavior in the seawater system different from those in the fresh water environments. In general, the leaching from the weathered ash was smaller than that from the fresh ash. However, it was revealed that the leaching of Si, Fe, Al, Mn, phosphate, and some other elements were independent of ash weathering. They were dependant only on the pH of the solutions.
