  • This studies were carried out to investigate the effects of the management of curing barn and the use of supplemental heat on prevention of barn rot during the rainy season. The managemental methods of curing barn were combined with hanging spaces ranged from 15cm to 30cm and ventilating conditions. The supplemental heat was applied with oil burner and oil fan heater. Barn rot was reduced in the wider hanging spaces, and the effects of hanging spaces was larger with ventilating during curing. Barn rot decreased by ventilating condition than non-ventilation. The use of supplemental heat dropped to lower relative humidity in curing barn. Supplemental heat and forced-air movement greatly reduced barn rot in comparison with tobacco cured under natural conditions.

  • Corruption in public offices can lead to corruption in overall society. Moreover, it can also result in steady growth of social expense caused by distrust in direct public relations of civil society administration. In order to devise a more comprehensive measure against corruption, it is essential to evaluate internal organization. This study suggests a scheme for improvement on fire officers' inter integrity, researched by in-depth interview. According to the study, there are numerous conventional corporate cultures remaining in the organization which fire officers are mutually trying to create reasonable and democratic corporate cultures. Furthermore, it was found out that structural issues of the organization, such as guaranteed anonymity of corruption prevention system, closed budget, et cetera, are the mostly dissatisfactory factors other than individual matters of the organizational members.

  • A construction project consists of many types of contracts. In the process of selecting the successful contractor after bidding, there will inevitably be fierce competition, which may lead to corruption or bribery. Even after signing the contract, during the period of settling the amount of the contract, bribery could occur. Such corruption could harm the development of the construction industry. It is, therefore, necessary to establish a strategy to prevent corruption by strengthening the transparency of the bidding process. In this study, to prevent corruption in the construction industry, a new service is proposed in which the successful bidder is selected by a professional third party, and the introduction of diverse delivery systems for construction projects and the invigoration of alternative methods of settling disputes are also proposed in this study.

  • This study was carried out to investigate the effect of environmental conditions of air temperature and relative humidity, varieties, and water content of leaves at harvesting time on the occurrence of barn rot during curing of burley tobacco. The curing environmental condition was combined with 4 air temperatures ranging from 25$^{\circ}C$ to 40$^{\circ}C$ and 3 different relative humidities. The harvested leaves with 3 different water contents were cured during the rainy season in curing barn. Barn rot occurred the most at 30$^{\circ}C$, and reduced at 25$^{\circ}C$ and remarkably decreased at above 35$^{\circ}C$. But no barn rot was observed at 40$^{\circ}C$. In influence of relative humidity, the percentage of rotten leaves was highest at 100% RH and remarkably reduced at lower RH. Among two varieties, KB 101 was rotted smaller than Burley 21 under the all temperature and relative humidity conditions, however those considerably showed no difference. The rate of disease development increased in the lower leaves more than in the upper leaves. In the water content of leaves at harvesting time, 29.5% of the rotten leaves was observed at W.S.D. (water saturation deficit) 10.3%, but no barn rot was found at W.S.D. 6.4%.

  • This study was conducted to extend the storage period of onion. After pre-drying process of onion, its storage was investigated at room temperature during a month. When ozone was treated with the concentration of 3 ppm in warehouse, the weight loss and the rotten rate of onion were remarkably decreased compared with control. Typical odor of onion was completely removed by the ozone treation during the storage.
