The objectives of this study were to investigate weather conditions which induced discolored grains and viviparous germination, and to evaluate yield responses following viviparous germination during mid- and late- ripening stage, the submergence during reproductive growth stage, and lodging in the yellow ripe stage. Weather conditions which caused glume discoloration at heading stage were 21.3-26.4℃ in average temperature, 75.2-98.4% in relative humidity, 19.3 in transpiration coefficient and 10.8-13.8 m/sec. in wind speed. Yield reduction was 26-27% and 10∼17%, respectively, when the glume discoloration rates were 63.2-65.7% and 38.3-45.2%, obviously due to the decrease in percent of fertile grain and ripening ratio. Weather conditions during continuous rain for 7 days were 96% in relative humidity, 18.9℃ in average temperature, 21.9℃ in maximum temperature, and 16.8℃ in minimum temperature, causing the most viviparous germination in Juanbyeo(45.5%), followed by Jinbubyeo(14.5%), Bongkwangbyeo(14.2%), and Obongbyeo(12.6%). Lateral tillers started to occur when the submergence at the depth of 1.5-2 m lasted one day during the reproductive growth stage. The submergence for 2-3 days at 3-4 m of water depth induced 269-571 lateral tillers/㎡, supporting 32-52% of the total yield. The rice yield in the paddy fields which were left under the lodging conditions until harvesting was not different compared to that of the paddy fields which were kept upright by tieing them together after lodging, but perfect grain ratio decreased about 9.1% in the transplanting culture and 12.5% in the direct seeding culture on dry paddy field because of the increase in immature grains.

The purpose of this study was to investigate the effect of forest healing program activities using natural environments on life recognition and prosocial behavior of child. Kindergarten children in Cheongju City were divided into two test groups and a control group. Test Group A participated in the forest healing program at the Infant Forest Experiences Center, while Test Group B had forest healing program activities in the classrooms of early childhood education institutions. Control group did not carry out the forest healing program but carried out the program by the Nuri Curriculum. The forest healing program was conducted once a week for a total of 12 sessions, each session lasting one hour. The forest healing program is based on physical and chemical sensory factors through the five senses. The effect of the forest healing program, and the data were analyzed by one way ANOVA and covariance analysis (ANCOVA). According to the result, the children of Test group A showed greater improvements in all sub-factors of respect for life (perspective on respect for life, knowledge of respect for life, and cooperative behavior with respect for life) than Test group B or Control group. Test group A also showed an increasing trend in all sub-factors of prosocial behavior (ability to regulate personal emotions, ability to build interpersonal relationships, and ability to adapt to kindergarten). The forest healing program using natural environments showed significant effects on the respect for life and prosocial behavior for 5-year old children.

IMPLEMENTATION OF A DECISION SUPPORT SYSTEM FOR INTEGRATED RIVER BASIN WATER MANAGEMENT IN KOREA

Shim Soon-Do,Shim Kyu-Cheoul Korea Water Resources Association 2004 Water engineering research Vol.5 No.4

This research presents a prototype development and implementation of Decision Support System (DSS) for integrated river basin water management for the flood control. The DSS consists of Relational Database Management System, Hydrologic Data Monitoring System, Spatial Analysis Module, Spatial and Temporal Analysis for Rainfall Event Tool, Flood Forecasting Module, Real-Time Operation of Multi Reservoir System, and Dialog Module with Graphical User Interface and Graphic Display Systems. The developed DSS provides an automated process of alternative evaluation and selection within a flexible, fully integrated, interactive, centered relational database management system in a user-friendly computer environment. The river basin decision-maker for the flood control should expect that she or he could manage the flood events more effectively by fully grasping the hydrologic situation throughout the basin.

본 논문은 공간의사결정지원시스템의 시범시스템으로서, 다목적 저수지군의 실시간 통합유역홍수조절 시스템에 대한 연구이다. 본 공간의사결정지원시스템은 자료관리시스템, 실시간 기상 및 수문자료 모니터링시스템, 저수지군의 모의 및 최적화를 모형기반시스템, 시스템의 효율적인 사용을 위한 사용자편의시스템으로 구성되어 있다. 홍수사상 동안에 수시로 갱신되는 홍수 수문자료의 공간적인 분포를 예측하여 제공하기 위하며, 신경망 알고리즘이 사용되었다. 예측자료는 유역 저수지군의 게이트조절을 위한 최적화 전략수립을 위한 입력자료로서 활용된다. 본 시스템은 1995년 한강유역의 홍수사상에 적용되었으며, 하류의 홍수피해를 최소화하면서 홍수기 이후의 수자원확보를 최대화할 수 있는 운영률을 제시하였다. A prototype spatial decision support system (SDSS) is presented for integrated, real-time river basin food control in a multipurpose, multireservoir system. The SDSS integrates a GIS with a database management subsystem, a real-time meteorological and hydrological data monitoring system, a model-base subsystem for system simulation and optimization, and a graphical dialog interface allowing effective use by system operators. The model-base subsystem employs an artificial neural network in a real-time flood forecasting module providing spatially distributed forecasted flows that are updated as the flood event progresses. Forecasted, basin-wide discharges are input into a dynamic programming module providing optimal gate control strategies, which are also updated in real-time. The SDSS for flood control is applied to the Han River Basin in Korea and demonstrated through simulated application to a severe 1995 flood event. Results of the case study indicate that integrated operational strategies generated by the SDSS for flood control substantially reduce downstream flood impacts, while maintaining sufficient conservation storage for water use subsequent to the flood seas.

In order to utilize the limited water resources, it is strongly desired to develop a system for optimal operation of the multipurpose reservoir system easily with visualization of inflow, storage, release, and etc. However, in the water resources management problem, the user of reservoir operation models is often trapped in an ambiguous situation because not only are most reservoir operation models very complex but also building their data is not so easy. However, this difficult problem may be approached using concepts of artificial intelligence. Expert systems, one branch of artificial intelligent programming, is used as an interface between the user and models. This fancy user interface help the user to build the data using the database, run the models, analyze the results and decide on the optimal operation rules for the reservoir operation problem. Moreover, the hybrid expert system, one concept of the expert system, lets us make the user interface easily without changing or converting the algorithmic models into an expert system programming language. Using the above concepts, a user friendly Graphical User Interface (GUI) for the Chungju, Soyang, and joint operation for the both reservoir has been developed. Not only 261 optimal operation rules but also 261 judgmental rules or heuristics for the Chungju reservoir have been collected and developed by the CJDP model. For the verification and validation of the developed GUI, a case study in Chungju Reservoir has been described. In this study, the overall concept and implementation of the hybrid expert system are described.

INTEGRATED WATER RESOURCES AND QUALITY MANAGEMENT SYSTEM USING GIS/RS TECHNOLOGIES

Shim, Kyu-Cheoul,Shim, Soon-Bo,Lee, Yo-Sang Korea Water Resources Association 2002 Water engineering research Vol.3 No.2

There has been continuous efforts to manage water resources for the required water quality criterion at river channel in Korea. However, we could obtain the partial improvement only for the point sources such as, waste waters from urban and factory site through the water quality management. Therefore, it is strongly needed that the best management practice throughout the river basin fur water quality management including non-point sources pollutant loads. This problem should be resolved by recognizing the non-point sources pollutant loads from the upstream river basin to the outlet of the basin depends on the landuse and soil type characteristics of the river basin using the computer simulation by a distributed model based on the detailed investigation and application of Geographic Information System (GIS). The purpose of this study is consisted of the three major distributions, which are the investigation of spread non-point sources pollutants throughout the river basin, development of the base maps to represent and interpret the input and outputs of the distributed simulation model, and prediction of non-point sources pollutant loads at the outlet of a up-stream river basin using Agricultural Non-Point Sources Model (AGNPS). For the validation purpose, the Seom-Jin River basin was selected with two flood events in 1998. The results of this application showed that the use of combined a distributed model and an application of GIS was very effective fur the best water resources and quality management practice throughout the river basin
