This study was conducted to evaluate the influence of dried swine excrement on the germination of Pinus thunbergii seeds, the growth response of seedlings of Pinus thunbergii and the uptaken of nitrogen and phosphorous by seedlings of Pinus thunbergii. The germination rate of seeds of Pinus thunbergii tends to decrease according to the increasing of application amount of dried swine excrement and the application amounts of dried swine excrement which is more than 3%(w/w %) makes the rate of germination to much more decreased. Contents of nitrogen and phosphorus are much higher in a way that the dried swine excrement was treated in nursery soil. 179 days after seeds of Pinus thunbergii were sowed, nitrogen contents in soil was decreased more than 70% and phosphorus was decreased 20 to 45%. Growth response of Pinus thunbergii was much higher in treatment of dried swine excrement than in control. But growth response was not affected by increasing of application amounts of dried swine excrement. Growth response of Pinus thunbergii was the highest in 2%(w/w %) application but its growth response was decreased in treatment more than 3% (w/w %) of dried swine excrement.

This paper briefly charts the history of excrement as part of the late 20th-century art and explores ways in which excrement functions in the realms of 'High' art. From Piero Manzoni's to David Hammons' performance , excrement has taken a small yet distinctively important part in the development of contemporary art. In an attempt to challenge the hegemony of 'high' art, on the one hand, and resist the commercialization and fetishization of art, on the other, Manzoni allegedly offered his own "shit" preserved in a tin can and sold it at the price of gold of the same weight. Andy Warhol took the legendary Abstract-Expressionist painter Jackson Pollock as the object of parody, simulating Pollock's dripping action by pissing onto the canvas that had been primed with copper-based paint. Warhol's urination produced splashes and stains of iridescent colors just as the patterns on ordinary abstract paintings. In contrast to Pollock's masculine action, Warhol's pissing alludes to the artist's homosexuality. Excrements in art also provoked controversies, debates, and even acts of vandalism against the artworks. The works of Andres Serrano and Chris Ofili infuriated many Christians for the blasphemous use of excrement with religious icons. Politicians engaged in the heated debates on the use of public and national funds in support of some of the 'politically incorrect' contemporary art. In the midst of media sensation and criticisms, these works challenged the conventional understanding of artistic beauty. The preexisting artworks were also targeted. African-american artist Hammons assumed the role of spectator in by urinating on Richard Serra's sculpture in the street of New York City. It was an act condemnation levelled at the racist pattern of the way in which large portions of funds and commisions of "public" art tended to promote established 'white' artists, whose work or creative process often failed to reflect the actual public. The use of excrement in art is not unusual in contemporary art practices. With its subversive power, excrement plays an important critical roles in the shaping of contemporary art.

Prunus serrulata var. serrulata f. spontanea (E. H. Wilson) C. S. Chang was treated with dried swine excrement at various concentration levels, and their growth reactions and the contents of total kjeldahl nitrogen and total phosphoric acid were analyzed. The result is as follows; 1. When the plants were treated with 0.25% of dried swine excrement, the seed germination rate of Prunus serrulata var. serrulata f. spontanea was higher than that of the control. However, it showed a tendency to decrease when the treatment concentration got higher than 0.25%. 2. The growth rate of species was highest when they were treated with 0.25% of dried swine excrement. It tended to decrease with higher treatment concentration than 0.25%. Significant difference was clear between the control and the experimental plants of Prunus serrulata var. serrulata f. spontanea. 3. The contents of nitrogen and phosphoric acid in Prunus serrulata var. serrulata f. spontanea also got higher as the concentration of dried swine excrement increased. However, the content of total kjeldahl nitrogen was highest in the leaves, and followed by the roots and stems. In contrast, the content of total phosphoric acid were highest in the roots, and followed by the leaves and stems. Therefore, stems had the lowest contents of both nitrogen and phosphoric acid. 4. The contents of total kjeldahl nitrogen and total phosphoric acid in the soil were measured before and after the growth experiment of Prunus serrulata var. serrulata f. spontanea treated with dried swine excrement. The contents of nitrogen and phosphoric acid significantly decreased after the experiment. In conclusion, the contents of total kjeldahl nitrogen and total phosphoric acid accumulated in the plants increased as the concentration level of dried swine excrement got higher. The seed germination and plant growth rates were best at 0.25% treatment of dried swine excrement. The treatment of dried swine excrement may bring high effects on increasing the plant growth rate but could damage the plants with higher concentration than they need. Different optimal concentration levels of dried swine excrement for different plants should be found before it is used as fertilizer.

Management of Swimming pool is focused on Swimming pool samitation in relation with chlorination of swimming water and potable water, disposal of waste and excrement within the boundry of swimming pool that may be summerised as follows: 1. Chlorination of Swimming Water Residual chlorine must be kept within the range of $0.4\~0.6 mg/l$ and in case of chloramine should be $0.7\~1.0mg/l$ while swimming pool is in operation 2. Chlorination of potable Water Residual chlorine must be kept within the rangs of $0.2\~04 mg/l$ at all time 3. Disposal of litters must be kept in the water tight waste bin with fitted lid, and waste should not be overflow -out of the bin. When waste in landfilled, the sufficient amount of cover material should be used daily. 4. Disposal of excrement Toilet must be water-flush type. However, The establishment of pit latrine is unavoidable the excrement must be covered with lime or dirt so that excrement should not be exposed to air.

This study was on a recyling system of food waste using poultry and earthworms. Food waste was fed to the egg-raising hens(Gallus gallus) or ducks(Anas platyrynchos). And the excrement of poultry after ingestion of food waste was mixed with other organic waste such as paper mill sludge or night soil sludge, aged and then provided to the earthworms(Eisenia andrei). An egg-raising hen and a duck ate up 0.40kg and 0.79kg of food waste per day, respectively. And the percental rate of exctretion(the amount of excrement/the amount of food waste eaten up) of an egg-raising hen and a duck was 71.0% and 53.7%, respectively. The excrement of poultry that had been mixed with paper mill sludge and aged was vermicomposted more easily than the excrement that had been mixed with night soil sludge and aged. The excrement of poultry aged for more than 21 days was more suitable to vermicompost than the excrement of poultry aged for less than 21 days. Even though, the earthworm lost its biomass on the mixed feeds regardless of their aging periods, which was supposed to be caused by high salinity in poulty's excrements.

In this paper, we propose a integrated real-time monitoring system for recycling agriculture resourcing based on USN. We design and implement the monitoring system so that we can integrate the quality control of farmyard and liquid manures, barn environment monitoring, and positioning information control into a total management system performing recycling of excrement and manure. Selection of sensors and sensor-node construction and requirements, structure of wire/wireless communication networks, and design of monitoring program are also presented. As a result of operating our system, we can get over various drawbacks of conventional separated system and promote the proper circulation of excrement up to the farmyard. We confirm that these advanced effects arise from the effective management of the total system integrating quality control of farmyard/liquid manure, barn/farmhouse information, and vehicle moving monitoring information etc. Moreover, this monitoring system is able to exchange real-time information throughout communication networks so that we can construct a convenient information environment for agricultural community by converging IT technology with farm and stockbreeding industries. Finally we present some results of processing using our monitoring system. Sensing data and their graphs are processed in real-time, positioning information on the v-world map offers various moving paths of vehicles, and statistical analysis shows all the procedure from excrement occurrence to recycling and resourcing.

Laying hens' excrement from eating food wastes was mixed with paper mill sludge, aged for 21 days and then provided to the juvenile earthworms(Eisenia fetida) for 10 weeks. Biomass of earthworm population decreased by 5.7% of initially introduced population. Very few juvenile earthworms developed into the clitellates and clitellated earthworms could not produce cocoons at all, which was supposed to be caused by inhibition effects of salts in laying hens' excrement upon the sexual development of Eisenia fetida. But there was no significant effect on the survivorship of earthworm population.
