International organizations have continued to promote policies that conserve the importance of water in the natural ecosystem. Crisis of the global environmental ecosystem and water are leading to large-scale natural disasters such as climate crisis and loss of biodiversity. Due to these, water management problems due to development, industrialization, and urbanization are emerging around the world, and international organizations such as the UN, OECD, UNEP, and FAO are promoting integrated water management policies as a new method for sustainable use of water. It is recommended. Korea government accepted the recommendations for integrated water management and enacted the Framework Act on Water Management in 2018 as legislation for a new integrated water management system over the existing water management system. The Framework Act on Water Management established a response plan for new climate crisis water management through the Water Management Committee, and was given the authority and role to promote the transition from the country to the watershed. After the National Water Management Basic Plan, the statutory deadline was exceeded by about a year, and the Four Major Rivers Basin Water Management Comprehensive Plan was completed on November 3, 2023, laying the foundation for the integration of the plan. Although the new system has begun, there are a lot of problems that need to be supplemented, such as basic concepts, systems, and procedures such as integrated water management and conformity review system. In particular, there are concerns about the level of integration of water management plans, which reach 250 per year, given the status and level of support of the Water Management Committee under the current Framework Act on Water Management. Although it may not be possible to fill the water from the first drink, we must lay the foundation for an integrated water management policy as soon as possible.

광원에 따른 국화의 화아분화 억제 효과를 보기 위 하여 형광등과 LED로 암중단 장일처리를 하였다. 청색 LED광원에 의한 광중단 처리시 ‘백마’는 평균초장 이 약 20 cm 정도 신장되고, 평균 생육일수가 약 20.1일 정도 되었을 때 조기에 발뢰되어 화아분화가 억제되지 않았다. 광원에 따른 개화소요일수는 형광등 55.5-61.0일에 비하여 혼합 LED처리에서는 약 0.7-4.6 일, 적색 LED처리에서는 약 5.6-9.3일 개화소요일수가 감소하였다. 따라서 화아분화억제 효과는 형광등과 혼 합 LED처리가 가장 크며, 적색 LED처리에 의해서도 어느정도 화아분화 억제 효과가 있는 것으로 나타났으 나, 청색 LED처리는 오히려 조기발뢰가 되는 것을 알 수 있었다. 형광등과 혼합 LED처리에 따른 절화장은 두 광원에서 우수하였으며, 통계적으로 비슷한 결과를 보였다. 절화중은 품종에 따라 다르게 나타났으며 ‘백 마’와 ‘핑크프라이드’는 형광등처리에 비하여 혼합 LED처리시 가장 무거웠으며, ‘신마’는 형광등에 비하여 가벼웠고, ‘일월’은 같은 경향을 보였다. 꽃목길이는 스 탠다드와 스프레이 국화 모두 적색 LED처리시 가장 짧았으며, 오히려 스프레이국화에서는 청색 LED처리 에서 긴 것으로 조사되었으며, 특히 ‘핑크프라이드’는 10.0 cm로 매우 길었다. 화아분화억제를 위해 36일간 4시간씩 심야에 조명한 전력소모량은 형광등 792.0 kw 에 비하여 혼합 LED에서는 234.7 kw로 70.4%가 절 감되었다. The experiments were conducted to determine the most efficient light source to prevent flower bud initiation during the vegetative stage in chrysanthemum cultivars. Light sources such as fluorescent lamp (control), red LED (light-emitting diode), blue LED, and red and blue LED (red/blue LED) were used for night-break during 4 hours (22:00-02:00) per day for 36 days. Blue LED showed early flower bud initiation and especially, it was emerged within 20.1 days after night-break treatment in ‘Baekma’. Days to flowering after short-day treatment were decreased by 0.7-4.6 days under red/blue mixed LED, and by 5.6-9.3 days under red LED compared with those under fluorescent lamp in 4 chrysanthemum cultivars. Therefore, prevention of flower bud initiation was the most effective under fluorescent and red/blue LED, and also under red LED up to a certain level, but under blue LED. The length of cut flower of red/blue LED was similar to the fluorescent lamp and that of red LED was smaller, and of blue LED was smallest because of early flower bud initiation. Compared to fluorescent, the weight of ‘Baekma’ and ‘Pink Pride’ was heavier, but of ‘Zinba’ was lighter, and ‘Ilweol’ showed similar weight under red/blue LED. Flower stalk length of standard and spray chrysanthemums was short under the red LED. Under the blue LED that of spray one was largely increased especially in ‘Pink Pride’ up to 10 cm. Electric power consumption for night illumination with 4 hours for 36 days for the prevention of flower bud initiation was 792 kw in the fluorescent lamp. Therefore, 70.4% of electric power was saved by red/blue LED.

In this paper, the four-pole elliptic function microstrip filter at 2.4GHz band with fractional bandwidth of 4% is realized using compact miniaturized hairpin resonators. The parallel algorithm FDTD method is used to analyze S-parameter of hairpin resonator filter more accurately, and to calculate the electric coupling and magnetic coupling among the hairpin resonators. Absorbing boundary conditions for mesh termination used Sulivan's simplified PML and the FDTD code was paralleled by MPI for IBM SP2 which had enhanced calculation speed. The experimental measurements are performed by HP8720D vector network analyzer. Measured results on fabricated hairpin type cross coupled bandpass filters show good agreements with theoretic results.

본 연구는 노인운전자용 자가 보고식 평가 SAFE-DR 개발 프로젝트의 일환으로 운전위험성 선별을 위한 기준점수를 확인하고 평가의 타당성을 검증하기 위해 수행되었다. Driver 65 Plus평가를 통해 노인운전자 132명을 58명의 위험성 운전자와 74명의 안전성 운전자로 구분하고, 이를 기준으로 SAFE-DR 평가의 위험성 예측 기준을 분석하였다. 또한 SAFE-DR 평가의 구성 타당도, 내용 타당도, 예측 타당도를 검증하였다. SAFE-DR 평가의 운전위험성 예측을 위한 기준점수는 74.5점으로 분석되었으며, 이 기준의 양성 예측도는 88.6%, 음성 예측도는 86.3%로 판별력은 훌륭한(excellent) 수준으로 확인되었다. 또한 집중타당성, 법칙타당성, 내용타당성이 적절한 것으로 판정되었다. 따라서 본 연구를 통해 SAFE-DR은 위험한 노인운전자를 선별하는 용도로 활용할 수 있는 적절한 평가임을 확인하였다. This study was conducted to test the assessment validity and examine the cut-off scores for driving risk as a part of the Self-report Assessment Forecasting Elderly Driving Risk (SAFE-DR) development project. The 132 senior drivers were categorized as either risky of 58 or safe of 74 drivers through the Drivers 65 Plus. Based on this initial assessment, we analyzed the risk prediction cut-offs. Furthermore, we tested the construct, content, and predictive validity. The cut-off score for the prediction of driving risk was found to be 74.5 points. The positive predictive value was 88.6%, and the negative predictive value was 86.3% about the cut-off score, signifying an excellent level of discrimination. Convergent validity, nomological validity, and content validity were found to be appropriate. Therefore, this study confirms that SAFE-DR is an appropriate assessment that can be used to screen dangerous elderly drivers.
