  • This paper investigates the current status of Jeju special self-governing province (JSSGP)'s water infrastructure and recommends directions for improvement. JSSGP relies on groundwater for most of its water resources. Recently, water usage has been steadily increasing due to the increase of residents and tourists while the quality of groundwater has been steadily worsening. Deterioration in water quality of groundwater can be seen through the increase in concentration of nitrate nitrogen and microorganisms. To overcome such problems, water consumption must be reduced by water demand management in all fields including residential and agricultural water use. The quality of water resources should be preserved through the management of pollutants. For efficient management of water resources, great efforts should be made to reduce the leakage rates in household and agricultural water, which is currently at the highest level in the country. Furthermore, diversification of water intake sources other than groundwater is needed, especially for agricultural water supply. For water and sewerage facilities, compliance with drinking water quality standards and discharge water quality standards must be achieved through the optimization of operation management. This process requires recruiting professionals, improving existing workers' expertise, and improving facilities.

  • Purpose: The aim of this study was to investigate the current status of the use of neglect test tools and the awareness for egocentric neglect (EN) and allocentric neglect (AN). Methods: A survey questionnaire was distributed to occupational therapists attending continuing education at the Daegu-Gyeongbuk branch on April 16. A total 143 responses were collected, and with the exception of 5 incomplete responses, 138 of them were analyzed. Results: The most commonly used unilateral neglect test tools were the line bisection test (86 responses, 62.3%), cancellation test (35 responses, 25.4%), copy and drawing test (7 responses, 5.1%). In a follow-up survey of 86 respondents who used line bisection tests as the most commonly used test, the majority (82 responses, 95.3%2) were found to use the 20-line test paper. In question about the familiarity and education experience for test manual, only 20 responses (23.2%) and 3 responses (3.5%) answered 'Yes'. In a question about the experience of a manual and the article for the manual, 25 responses (29.1%) answered 'Yes'. In the question regarding the separation of EN and AN on the unilateral neglect test, 44 responses (31.9%) were 'distinction' and 94 responses (68.1%) were 'no distinction'. Conclusion: Information on the guidance and interpretation of the line bisection test is lacking and the concept of EN and AN was insufficient.

  • Recently, most vehicles has the Automatic transmission system as their transmission system. The automatic transmission system operates with fixed shift patterns. In the opposite of manual operation, it is easy and convenient for driving. Though these merit, the system can not evaluate the driver's intension because of usage of firmed shift pattern. Especially, when the load has declination the AT system must operate for engine break effect. Namely, if the vehicle drives on the load of decrease, the acceleration of the vehicle goes to high then. At that time, the shift goes to down position the vehicle has some negative acceleration with the resistance of engine. To consider driver's intension in this case, we must consider both the driving intensity of driver and the status of load. In this paper, we developed flexible automatic transmission system by using the proposed moduled neural networks which can learn the status of the load and driver's intensity As a result, we compare the transmission system using firmed shift pattern and the proposed transmission system and show the good performance in the change of shift position.
