The present study investigated the changes in nutrient profile of sewage sludge during bioleaching in a batch mode of operation. The study identified the optimum bioleaching period at which maximum solubilisation of metals is achieved while maintaining the fertilising property of the bioleached sludge. The bioleaching experiments were performed using anaerobically digested sewage sludge by employing indigenous iron and sulphur oxidising microorganisms. The results showed that bioleaching using sulphur oxidising microorganisms is comparatively advantageous due to the higher solubilisation of heavy metals. However, despite its high potential in solubilisation of heavy metals from the sludge, the bioleaching process resulted in the undesirable dissolution/loss of sludge bound nutrients (nitrogen and phosphorus), thus making the sludge less attractive for land application as a fertiliser. After 16 days of bioleaching about 45% of the nitrogen and 34% of the phosphorus were leached from the sludge using indigenous iron oxidising microorganisms, whereas about 78% of the nitrogen and 56% of the phosphorus were leached using indigenous sulphur oxidising microorganisms. The findings indicated that the fertilising property of the sewage sludge can be maintained by conducting the process for a shorter duration of time (up to 10 days). The optimum bioleaching period was 10 days where about 85%Cu, 71%Ni, 91%Zn and 61%Cr were solubilised from the sludge while the loss of nitrogen and phosphorus was only 56 and 51% respectively, by using sulphur oxidising microorganisms. The heavy metals remaining in the bioleached sludge were mostly in the residual fraction ensuring the safe disposal of bioleached sludge for land application as a fertiliser.

Now, our society become 'an aged society' and then the problem of old men's life are quiet serious. At the literature, there are a few works that represents dementia nd family conflicts but there are few works the old men say their viewpoint. Around 2000th. Park-wan-seou, Choi-il-nam and Kim-won-il, they are so-called 'old men', write old men's novels. Three novelists say the age of old at the other point. Park-wan-seou try to tell just a human, better than the old men, and solve the problem family conflict. She grow old herself, recognizes her ages. Choi-il-nam express at the problems of old men's daily life and the death, always lightly. It is very interesting and fresh old men's novel style. Kim-won-il's novels are different two the works. He shows the last time four old men life. Four persons had stormy career each other. Sometimes they tried to live only theirselves, sometimes help other people, make a mistakes. Kim-won-il asks the readers what is a true life or false life. Three writers acquire a special meaning that we should be an old man and die. Key words : Park-wan-seou, Choi-il-nam, Kim-won-il, old men's novel, the death, what is a true life or false life.

This study is to analyze the trends of the formal expression of contextual attitudes about the local theme museums in Japan. Architectural design by the contextual codes has been considered as an appropriate way to build up the regional identity in these days. After a theoretical study on 'Context', a statistical analysis was processed about the correlations between the types of the locations and the types of forms related with the elevation. At the last stage of the study, the specific methods for expression were studied. The contextual attitudes of continuity characterized into two concepts like continuity and resemblance. As the result of the research, the contextual forms appeared strong with such location types as beaches or plains comparing to mountains or downtown. On the other hand, the conditions of mountains or downtown tend to make the form complicated and divided for adjustment to the context of surroundings. The various expression methods like unifying with the land, applying the configuration of the ground to the shape of the building, using the clear or reflective materials and dividing the mass were researched as helping continuity and resemblance between building and landscape.

Costume has been steadily changed and developed, not only creating the mode, but also fading it according to the social change of many historical events the French Revolution(1789) was a very meaningful on in reforming costume conspicuously as well as in establishing the modern European history. Accordingly this study aims to present how costume, headdress, hat, shoes, and ornaments, etc. from the Rococo<1714~1789> to the Empire<1789~1815>. 1. In clothes, culottes, the short trousers was changed into today's pantaloon through sans-culottes, merveilleuse clothes into highwaist, chemise into Y-shirt, cravate into necktie and veste into waistcoat. Aristocratic costume disappeared ; and the civil one led the major-style while redingote provided variant designs for women overcoat. And in colour the conventional black vanished, namely the democratization of clothes was practiced. 2. In hairdress and hat, men had short hair, and the simple formed-hat appeared, for example chapeau with high crown ;it showed the pragmatic tendency. In women's hair and hat, the archaic style titus and short curled-hair were prevalent, which was the resurrection of the old fashion. And oriental shawl and luxurious turban imported through Napoleonic external wars were in mode, which showed the influence on the costume of the political condition. 3. In shoes, men wore comfortable low-heeled pumpus and boots suiting for their clothes. Women wore escarpin comfortable in wearing and Greek styled-shoes, but in fact there was no great change in comparison with clothes or hairdress. 4. In ornaments, watchpocket, seal which hung under the watchpocket and gloves were men's major accessories. Women carried the portable folding-fan with them, and used to wear gloves becoming to shoes. 5. In clothes, practical ones such as wool and textile were favored because of the economically poor situation just after the Revolution. However, after Napoleon's accession to the thron material and colour of clothes become colourful and bright according the the internal reformation and beautification of Paris. These phenomena imply that economical conditions make materials of clothes simple or exuberant. And after the French Revolution the democratization of clothes was practiced and civil costume oriented to the new mode was fixed, while the aristocratic tendency was demolished. In short costume after the Revolution became the turning point of modernization.

This experiments were conducted to test the equations of Gas Test to predict in vivo metabolisable and net enengy values for ruminant feedstuffs. The feedstuffs for experiment were 20 compounds and 19 forages. The results obtained are as follows ; 1.The prediction error(PE%) of equations to evaluate ME valus of compound was 0.92∼1.35%, and PE% of equations for NEI was 1.10∼1.71% 2.For forages, PE% of ME equations was 0.98∼1.39% and that of NEI equations was 1.25∼1.72%
