Yongdam multipurpose dam is under construction to divert a part of Geum riverflow to Mankyung watershed and to supply the domestic water to the Chunju region and produce the hydro-electricity. Generally, construction of dam by the method of inter-regional water transfer affects the quantity and quality of water in the down streams and reservoirs. The impact of operation plan of Yongdam dam on the quantity and quality of water in the Geum river and Daechung dam was investigated. It was recommended that the discharge of water transfer from one watershed to another should be minimized as much as possible.

Background: This study was designed to analyze the current emergency department(ED) medical records of teaching hospitals in Korea. Methods: The five-item questionnaires were mailed to the EDs of 40 hospitals. Among them, 27 questionnaires and 35 ED medical records were returned for reply rates of 67.5% and 87.5%, respectively. Results: 1) The actual number of data elements in the ED medical records used by each hospital varies widely. It ranges from 1 to 15 data elements with an average of 7.5 data elements. 2) Thirteen data elements, signature of nurse, checklist style in review of systems, checklist style in physical examination, neurologic examination, figure of face, Glasgow coma scale, trauma scale, treatment plan, mode of transfer, condition on transfer, documents sent with patient, condition on discharge or discharge instruction, use of pediatric chart and vaccination history are used by less than 50% of the medical records examined. 3) There was no difference in the total number of data elements or in redesign and computerization of ED medical record based on the location of the hospital, the type of hospital administration, or the number of years since the start of EM residency program. 4) There was a statistically increased number of data elements in redesigned medical records. 5) In the survey, 89% of the residents replied that medical records needed to be redesigned. With respect to uniformity, 58% of the residents disagreed. A well-designed checklist chart rather than a descriptive chart was preferred by 89% of the residents. Conclusion: The currently used ED medical records have much room for improvement. The age of the ED had little impact on the quality of ED medical records. More attention and effort in this field are needed. In addition, The Korean Society of Emergency Medicine should provide guidelines for ED medical records.

The results of the study on the effect of extending the freshness maintenance period by controlling the growing environment such as growth temperature and humidity of Pleurotus eryngii for export are as follows. The temperature in the growth room was maintained at 17°C from the time of scratching P. eryngii until the formation of young mushrooms, then at 16°C and 12°C untill 2 days before harvesting. However, the control was maintained at 16 ℃ until the completion of the harvest. Relative humidity is maintained at 90% until 2 days before harvesting and then lowered to 85% from 2 days before harvesting (T2). A treatment group (T3) that was controlled as low as 80% from 2 days untill harvesting. Control (T1) was maintained at 90% until the end of the harvest. Growth days were 15 days in the control group, while 16 days in the T2 and T3 treatment groups took 1 more day. There was no difference between the amount per bottle and the pin-heading rate. The hardness of the fruiting body was harder than the T2 and T3 treatments than the control. When stored at a low temperature of 1 to 2°C, freshness was maintained for control (T1) for 50 days, but freshness was maintained for T2 and T3 treatment for 60 days. In addition, when stored at room temperature at 20°C for 8 days after low temperature storage at 1∼2°C for 10 days, 20 days, and 30 days, freshness was maintained at room temperature (20°C) for 8 days after T3 treatment was stored at room temperature for 30 days.

This study was performed to develop a soil loss reduction skill through estimating soil loss from each type of sloping upland by using GEOWEPP model based on GIS Interface. Experimental watershed is located at Yongsan-ri Doam-myeon, Pyeongchang-gun, Gangwon-Do and include a very typical sloping upland fields in Alpine area. Dem(5m×5m), Soil type map(1:5,000), land cover map were used as input data for GEOWEPP model. for the making more detailed topology map and land cover map, GPS and Total station survey was done. 6 Water level gauges and 1 Rainfall gauge were installed for the monitoring run off discharge, sediment load and hourly rainfall amount occurred from each event of storm. other weather data was obtained from Daegwallyeong weather station. Ultimately, Estimated results of GEOWEPP simulations for Experimental site was reasonably satisfactory. This study indicated that GEOWEPP model could be applicable to estimate soil losses from Sloping Upland Field.
Characteristics of a new oyster mushroom variety 『Gongi-2ho』for the bag culture
Jong-In Choi,Dae-Hoon Jeon,Tai-Moon Ha,Young-Cheol Ju 한국버섯학회 2010 한국버섯학회지 Vol.8 No.4
‘Gongi-2ho’a new variety of oyster mushroom, fitting for the bag culture, was bred and by mating between monokaryons isolated from GMPO35338 and Jangpug. In the major characteristics of fruit body, the pilei were thick and dark-gray and the stipes were thick and long with softness. It was great in elasticity and cohesivness of tissue as compare to Suhan-1ho. The optimum temperature for the mycelial growth was around 26~29℃ and that for the pinheading and growth of fruitbody was around 14~18℃. In the bag culture, it was required around 20 days in incubation period and 5 days in primordia formation. The fruit body was grew vital and uniform. The yield were shown by 323.3g/1kg bag. This variety has high yielding capacity, cultivation stability and the resistance to the bacterial brown blotch disease.
방동저수지 유역의 토지이용에 따른 비점오염 부하발생 원단위 산정
문종필,김태철,안병기 충남대학교 농업과학연구소 1999 농업과학연구 Vol.26 No.2
1. 방동저수지 상류 5개 토지이용별 유출수량과 수질조사를 실시하고 비점오염원 원단위를 산정하였다. 산지에서 SS 84㎏/ha년, BOD 4.2㎏/ha/년. COD 15㎏/ha/년, T-P 0.1㎏/ha/년, T-N 1.1㎏/ha/년으로 배출부하원단위가 가장 작았다. 거주지역에서 SS 319㎏/ha/년, BOD 34㎏/ha/년, COD 98㎏/ha/년, T-P 5.6㎏/ha/년, T-N 8.7㎏/ha/년으로 배출부하 원단위가 가장 많았다. 2. 비점오염원은 강우-유출과 관련이 있어 전체 비점오염원의 약 46%가 7~8월에 유출되며, 건기인 10월에서 4월까지는 연간 총량의 약 20%, 5월에서 9월까지는 약 80%가 유출된다. 3. 유기물질은 SS, BOD, COD는 거주지역에서, 영양물질인 T-N은 논·밭지역에서 T-P는 논·밭·거주지역 및 방목지에서 많이 유출되고 있다 . 4. T-N, T-P등 영양물질이 농지에서 많이 유출되어 저수지와 같은 폐쇄수역에 부영양화로 인한 수질악화의 원인이 된다. 비점오염원이 우기에 집중배출되어 공공수역에 큰 오염원으로 작용하므로 도시하천을 이용한 비점오염원 관리방안과 비점오염원 발생원 저감방안을 적극 추진하여야 한다. The water quality of river has been deteriorated mainly by both point source pollution and nonpoint source pollution from the watershed. Techniques to cut point source pollutants down to the level required have been developed. But, techniques of best management practices to catch the nonpoint source pollutions and to control the routine of pollutants were not successively developed. The quality of closed water system such as reservoir, lake and farm pond is irresistable to being polluted mainly by nonpoint source pollutions. In this study, the population, land use, runoff coefficient, amount of rainfall, and runoff discharge in the watershed were surveyed to investigate the characteristics of water quality such as BOD, COD, SS, T-N, and T-P. After studying the changes of water quality in the viewpoint of land use such as paddy land, residential area, upland, forest and meadow, load factors of nonpoint source pollutant were calculated in Bangdong reservoir watershed. Residential area was more severe than other land use as far as BOD, COD and SS concerned T-N and T-P released from the paddy and upland were higher than other land use. The 45.9% of total load of nonpoint source pollution was occured during the rainy season.
