養鷄 主飼料인 옥수수 代置飼料로서 小麥利用에 關한 硏究 : 第 1報 옥수수 代置飼料로서 小麥의 利用水準 Ⅰ. Utilization Level of Wheat as a Substitute Feed for Corn

河正基,李炳五,郭鍾瀅,安炳弘 慶尙大學校 1972 論文集 Vol.11 No.-

初生雛 育成飼料의 主飼料인 옥수수의 代置飼料로서 밀을 이용한 代置水準을 究明하고저 本 實驗을 實施하였던 바 그 結果는 다음과 같다. 1. 增體量은 옥수수와 밀을 各各 50%씩 使用한 區와 밀보다 옥수수를 많이 使用한 區가 밀 만을 使用한 區에 비해서 增體量이 좋았다. 2. 飼料攝取量은 옥수수를 제일많이 使用한 區가 제일 적었고, 반대로 밀을 많이 사용한 區 일수록 높았다. 3. 飼料效率은 옥수수와 밀을 50%씩 使用한 區가 옥수수와 밀의 單用區 보다는 좋았다. 4. kg增體에 所要된 飼料費는 옥수수와 밀을 50%씩 사용한 區가 제일 낮아 本 試驗에 의하면 養鷄配合飼料의 穀類 60%中 밀을 30%程度 使用할 수 있다고 하겠다. To investigate the substitute level of wheat for corn used as major ration of laying hen, was carried out. The results obtained were as follows: 1. Body weight gain was higher in the treatment of Corn 50% : Wheat 50% and in used more corn than wheat in contrast with the treatment used only wheat. 2. Diet intake was least in the treatment used only corn and on the other hand, the only wheat was higher than other treatment used corn in the diet intake. 3. Feed efficiency was more improved in the treatment used 50% of wheat and corn, respectively than in the treatment used only wheat. 4. Feed cost required per kg body gain was lowest in the treatment used 50% of wheat and corn. Therefore, according to the present experiment it may be to say that s0% of wheat will be substituted for corn in the formulated ration of laying hen using 60% cereals.

옥외 라돈이 호흡기관에 주는 선량을 측정·평가할 목적으로 CR-39 비적검출기를 내장한 라돈컵을 사용하여 대기중 라돈농도를 측정하였다. 직접형 검출기 및 개방 컵과 필터 컵의 구조를 갖는 CR-39비적검출기에 대한 라돈검출인자는 공기중의 농도가 잘 알려진 표준라돈 조사시설에서 이들 검출기와 라돈컵을 일정기간 조사하여 결정하였다. CR-39를 70°c, 30% NaOH용액으로 220분간 화학부식하였을 때 직접형 거출기와 개방 컵, 필터 컵에 대한 라돈검출인자는 각각 0.273, 0.0813, 0.0371tr mm-2/37 Bqm-3·d)였다. 또한 1988년 5월에서 1989년 3월까지 대전(충남대학교)에서 측정한 대기중의 라돈농도는 개방 컵에 의한 결과는 27.4 - 135.8Bq/m3(0.74 - 3.67 pCi/l)로서 연평균 73.3 Bq/m3(1.98 pCi/l)이었으며, 필터 컵에 의한 결과는 16.7 - 143.9 Bq/m3(0.45 - 3.89 pCi/l)로 연평균 68.5 Bq/m3(1.85 pCi/)이었다. 측정한 옥외 대기중이 라돈농도와 부위별 폐선량모형으로부터 산출한 ICRP표준인의 호흡기관에 대한 실효 선량당량률은 약 520 nSv/h로 평가되었다. A study for the assessment of dose given by outdoor radon to respiratory system has been carried out by making use of radon-cups containing CR-39 plastic track detectors. Detection efficiencies were determined by irradiation of the radon-cups in a standard radon chamber of known concentration. Thus determined detection factors of CR-39 plastic track detector in bare, open cup and filtered cup geometry are found to be 0.273, 0.0813 and 0.0371 trmm-2/(37 Bqm-3 d), respectively, which are chemically etched in 30% NaOH solution of 70℃ for 220 minutes. The outdoor radon concentrations measured at Taejeon (Chungnam National University) from May 1988 to March 1989 are in the range of 27.4 - 135.8 Bq/m3 (0.74 - 3.67pCi/l) by open cup and 16.7 - 143.9 Bq/m3 (0.45 - 3.89pCi/l) by filtered cup, which yield overall annual average value of outdoor radon concentration of 70.8 Bq/m3 (1.91 pCi/l). Corresponding effective dose equivalent rate to respiratory system of ICRP standard man is assessed to be 520nSv/h.

This papers describes on the experimental consideration for the intrinsically-safe explosion-proof capability of rechargeable battery's body about main item, rechargeable battery and cellular phone battery which is selling in domestic that IEC(Intemational Electrotechnical Commission) recommend the measurement of ignition limit by short circuit of rechargeable battery and temperature increase test to use a explosion grade Group ΠC type of explosion-proof type apparatus test an object of hydrogen gas. Because of that, there are many different results for existence or nonexistence for ignition by different company and different types. It is concluded that the maximum of self temperature increasing by spark circuit of rechargeable battery is 180℃ in case of Nickel-Hydrogen, and 110C in case of Nickel-Cadmium. The reaction of cellular battery for external temperature have following processes. It is confirmed that the temperature of reaction is rise slantly as the ambient temperature rising, then exterior shape of one is swell up and change when the temperature of ambient reach to about 130~140℃, and when reach to about 160℃ the battery is blown up. Therefore, it is considered that have to be in considering selection of rechargeable battery using in itself due to different ignition limits of various rechargeable battery when the portable electric containing rechargeable battery are designed, produced and used, the characteristics and the proper safety factors of devices.

뇌실외 배액술 시행과 관련된 뇌실염 : 원인균주와 경험적 치료약제의 적절성

도병훈,김신우,오종택,손종원,하상우,이응갑,장현하,이종명,김능수 대한감염학회 2005 감염과 화학요법 Vol.37 No.2

목적 : 본 연구는 뇌실외 배액술을 시행한 신경외과 환자들에서 뇌실염 발생 빈도, 원인균주와 감수성 추이 및 경험적 치료로 사용되는 항생제인 ceftazidime과 vancomycin의 적절성 여부에 대하여 조사하였다. 재료 및 방법 : 2000년 12월부터 2003년 10월까지 EVD를 시행한 경북대학교병원 신경외과 입원환자 340명 중 뇌실염이 발생한 39명을 대상으로 후향적으로 조사하였다. 결과 : 340명 중 39예 (11.5%)에서 뇌실염이 발생하였고 이들 가운데 4명이 뇌실염과 연관하여 사망하였다(10.3%). EVD 시행일로부터 뇌실염 발생까지는 평균 8.4일이었다. 원인균은 33예(87.1%)에서 확인되었으며 Aci-netobacter (19예, 45%), methicillin-resistant coagulase negative Staphylococcus (9예, 22%), methicillin-resistant Staphylococcus aureus (9예, 22%) 등의 순이었다. 가장 많이 동정된 Acinetobacter 19예 중에서 8예(42.1%)가 ceftriaxone에 내성을 보였으며 현재 경험적으로 널리 사용되는 ceftazidime에 대해서는 11예중 3예(27%)가 내성을 보였다. 결론 : 최근 EVD 시행과 관련된 뇌실염 뇌실염 최근 그람음성 non-fermenter 특히 Acinetobacter에 의한 경우가 증가하고 있으며, 이들 그람음성 non-fermenter는 현재까지 경험적으로 사용되는 ceftazidime에 점차 내성을 보이고 있다. 경험적 치료제에 대한 성공률을 높이기 위해서는 각 병원별 내실염의 원인균주의 감수성에 대한 검사가 필요하겠다. Purpose : To investigate the etiologic microorganisms of external ventricular drain (EVD)-related ventriculitis and the appropriateness of using ceftazidime and vancomycin as an empiric therapy in neurosurgical patients with EVD-related ventriculitis. Materials and Methods : Retrospective analysis of 39 patients with EVD-related ventriculitis among 340 neurosurgical patients to whom EVD had been placed during December 2000 and October 2003 at Kyungpook National University Hospital. Results : Thirty-nine EVD-related infections (39/340, 11.5%) occurred and the attributable mortality rate was 10.3% (4/39). The average duration from the ventricular catheter placement to the development of ventriculitis was 8.4 days. All patients with EVD infection had fever and 89.7% (35/39) of the patients showed nuchal rigidity. The positive culture rate in CSF was 87.1% (34/39) and the frequency of individual organism is as follows : Acinetobacter 45% (19 cases), methicillin-resistant coagulase negative Staphylococcus 22% (9 cases), methicillin-resistant Staphylococcus aureus 22% (9 cases), Enterococcus 5% (2 cases), Streptococcus pneumoniae 3% (1 case), non-fermenting gram-negative bacilli 3% (1 case). The polymicrobial infection rate was 15.4% (6/39). Among 19 cases of Acinetobacter infection, 42.1% (8/19) of the strains showed resistance to ceftriaxone and 15.7% (3/11) to ceftazidime. However, all cases were sensitive to meropenem. Conclusion : These findings show that the major etiologic organisms causing EVD-related ventriculitis have recently changed to Gram-negative non-fermenters, especially Acinetobacter. Because Gram-negative non-fermenting rods resistant to ceftazidime are increasing, an immediate change from ceftazidime plus vancomycin, the widely accepted empiric antibiotic therapy, to meropenem plus vancomycin should be considered when clinical symptoms and signs show no improvement or even deterioration.

이라보유의 생성범위와 발색특성

To study the coloring on the range on the Irabo glaze of pine tree ash and oak tree ash, 2-and 3-components compositions are researched. And the coloring range of Irabo glaze and the coloration characteristics with the sample testing materials such as feldspar and potterystone are analyzed. As the fluxes, Pinetree ash, oaktree ash and limestone[ CaO glaze group ], beanchaff ash [ magnesia glaze group ] were used and detected the difference of the characteristics of glaze within the coloring range of Irabo. with these, the same procedure was applied to natural mineral 1imestone[CaC0_(3) ] to compare the differences with natural ash which has similar components. Iron(Fe2O_(3) ) as metal oxide and field clay and loess as the natural material were used as color formers, each of which were added with different content ratio. During the repetative process of gathering and scattering in fire, the glaze became more fluid when it was more influenced by strong alkali, which means that the generation of Irabo glaze has an intimate relation with the melting quality. We found out that the range of Irabo generation is broader whithin the feldspar-ash, potterystone-ash binary system than the fe1dspar^(+) potterystone-ash-silica ternary system. Further, the Irabo color formation and flow were more serene and soft in potterystone than feldspar. And within the ternary system, loess mixed with 5% iron and 4% fieldclay made a softer and milder galze when it was used as a break material than as a color former.
