Development of a Simulator for Prediction of Urban Environmental Loads : Parameter Identification Method in Multiplier and Verification of Model
No full textWe made a long-term prediction simulator of CO_2 emissions from 1975 to 2050 for Fukuoka City with system dynamics. In this simulator, CO_2 emissions are calculated by multiplying CO_2 emission units with amounts of activities. In our past research, it took many hours to make the model because we manually adjust multiplying functions of the model. Therefore we develop a program to adjust every multiplying function of the model for reducing the simulator making hours. Moreover, we compared actual values and calculated values of the simulator by using multiplying functions that were identified by the program, and did accuracy verification of the program

Reconstruction of Hama Castle and the Castle-town of Shimabara
No full textThe 1792 earthquake in Unzen caused the eastern flank of the Mayuyama dome to collapse, and the site of the Hama Castle and the southern half of the Castle-town of Shimabara, to be buried under the earth. Due to absence of accurate maps and scarcity of documents as well as topographical data, the castle and the castle-town has not been a subject of study for quite a long period of time. This thesis is about reconstructing the plan of the Hama Castle and the Castle-town of Shimabara, by analyzing every detail of documents and maps, and by focusing on features of the early Edo period maps. The study has unearthed several facts about how the city of Shimabara had been formed before the earthquake
The Optimal Dose and Spraying Method of Chemical Pesticides for Pest Control Effects in Apple Orchards
No full textIn this study, three apple orchards in Chungnam were selected to review pesticide sprayings conditions, pesticide deposit amounts, and pest control effects while spraying different spray water volumes by the customary methods. In the first orchard, the spray water volume of acetamiprid 8% WP targeting moths used in 2014 was 372 L/10 a and the one used in 2015 was 302 L/10 a, i.e. by about 70 L smaller as compared to the previous year; however, no difference in the control value was observed. Meanwhile, for control of A. citricola, acetamiprid 2.5% wettable powder was used; the spray water volume used in 2014 was 453 L/10 a and the one used in 2015 was 378 L/10 a, i.e. by about 70 L smaller as compared to the previous year. The well–sprayed sections showed pest control effects not lower than 95%, while the poorly sprayed sections showed pest control effects of about 78%. In the second and third orchards, the control target pest was G. molesta and the spraying pesticide used was acetamiprid 8% WP. The spray water volumes used in the second and third orchards were about 349 L and 378 L, respectively, and there was no problem in the control values. For control of A. citricola, imidacloprid 10% wettable powder and flonicamid 10% water–dispersible granules were used as spraying pesticides. The spray water volumes of these two pesticides were 355 L and 380 L per 10 a, respectively, i.e. smaller than the reference volumes; however, no problem in the overall pest control was observed. Therefore, our results suggest that pesticide deposit amounts on water–sensitive papers are proportional to increases in the dose; however, the dose exceeding the appropriate concentration is not related to the deposit amounts
