P^H, 燐酸施肥量이 大豆의 生育 및 收量에 미치는 影響
李宗玉 진주산업대학교 1977 論文集 Vol.15 No.-
This experiment was carried out to determine the level of soil P^H and the mount of phosphorus aplied to soybean plants, and the results are as follows. 1. There were high differences of number of pods per plant and stem diameter under treatments, but there were no differences of stem length under phosphorus treatments. 2. In the soybean yield, the level of P^H to 7 and 9㎏/10a phosphorus aplication was the hieghest yield with 136.8 of yield index, when the level of P^H to 5 and 6㎏/10a phosphorus application took 100 of yield index.

This experiment was conducted to investigate the distribution of both convention culture and photosynthesis bacterial treatments in paddy solis on growth and yield, as testing cultivar were used with daesan-bye from may to October in 2000 years at fields of chinju national University. The result were as follow : 1. In the case of growth and yield were the better treatments than non-treatment. 2. The time of good of Application to paddy soils was guess the period of culm internode elongation and heading stage which was twice application to paddy soils 3. Organic matters in paddy soils was maybe of increased for make of multiply with photosynthesis bacterial treatment.

The Search engined being used on World Wide Web are doing very important roles in search for internet information resources. But each search engine has its own characteristics and is considerably different especially in how to search the information resources. Because the retrieval effectiveness of search engine are deeply affected by which search engine are used, it is needed for the users to choose the search engine which is appropriate for job characteristics. Therefore, in this study, I intended to help the user to choose the proper search engine through the evaluation of the retrieval effectiveness of each search engine and as objects of study. I have selected three representative search engines in three search domains, which are Yahoo as the subject directory search engines, Alta Vista as the keyword search engines, and Simmany as the korean keyword search engines. To evaluate the retrieval effectiveness of each search engine, I input six search queries into the above three search engine and compared the results with each other in terms of the number of documents retrieved and that of the relevant documents retrieved, recall and precision ratios, and a couple of search queries. As a result, Yahoo showed the comparatively good performance in recall and precision ratios. Alta Vista was best in the total number of documents retrieved and rather poor in recall and precision ratio. And Simmany was good recall and precision ratio, compared to the foreign famous search engines like Yahoo, Alta Vista, but rather poor in a couple of search queries.

Purpose : Perinatal asphyxia occurring in newborn is one of the major causes of acute mortality and chronic neurological disability in survivors. We have studied the relationship between early electroencephalography(EEG) findings and clinical course and neurologic outcome in severe asphyxiated neonates. Methods : Between the period of July 1999 and June 2002, 25 neonates who were diagnosed with severe perinatal asphyxia(1-minute Apgar score of ≤3 and initial pH is less than 7.2) at NICU in Dongsan Medical Center were enrolled. An EEG was recorded and analyzed within three days of life and divided into two groups - group 1(normal or focal change on EEG) and group 2(generalized abnormal EEG). Between the two groups, clinical courses and neurologic outcomes were compared. Results : Fifteen infants(60%) were group 1 and ten infants(40%) were group 2(polyspikes, burst- suppression, generalized low voltage). Associated maternal disease, days of hospitalization, need for ventilator support, delay of oral feeding and convulsion duration are significantly higher and longer in group 2. Also, poor neurologic outcome(expire, developmental delay) was significantly higher in group 2(60%) than group 1(13.3%). Conclusion : Thus, the early neonatal EEG in asphyxiated newborn can be a predictable diagnostic tool in assessment of neurologic outcome. 목 적 : 주산기 가사 환아는 뇌손상 정도에 따라 다양한 임상 경과와 예후를 나타낸다. 이에 초기 뇌파의 소견이 저산소성 뇌증 환아의 임상경과와 예후를 예측할 수 있는지를 알아보고자 이 연구를 시행하였다.방 법 : 1999년 7월부터 2002년 6월까지 계명대학교 동산의료원 소아과 신생아 중환자실에 1분 Apgar 점수 3점이하의 중증 주산기 가사소견으로 입원했던 만삭아를 생후 3일 이내에 시행한 초기 뇌파검사 소견으로 미세 변화군(정상, 국소성 극파 혹은 서파)과 전반적 이상군(다형성 극파, 돌발-억제파(burst-suppression), 전반적 저전위파)으로 나누어서 각 군간 입원시 혈액검사소견(암모니아, 요산, 젖산, pH), 임상소견(입원기간, 산전 모성 위험인자 유무, 경련유무 및 지속기간, 기계적 환기 필요여부, 경구수유 시작시기), 예후(사망 혹은 발달장애 유무) 등을 비교하여 통계적 분석을 하였다.결 과 : 총 25명 중 미세 변화군은 15명, 전반적 이상군은 10명이었으며 양군 모두 외부 출생아가 70% 이상으로 많았다. 두 군간 성별, 평균 재태 기간, 출생 체중은 유의한 차이가 없었다. 미세 변화군에 비해 전반적 이상군에서 산전 모성 위험인자 내재(20.0% vs 60.0%), 평균 경련 지속기간(1.5일 vs 5.5일), 기계적 환기가 필요한 경우(20.0% vs 60.0%) 및 경구수유 시작시기(3.2일 vs 9.9일)가 의미있게 늦었으나 경련 동반율(66.7% vs 100.0%)은 유의한 차이가 없었다. 사망 혹은 발달장애를 동반한 나쁜 예후로의 진행은 미세 변화군 중 13.3%에 비해 전반적 이상군 중 60.0%로 의의있게 많았다(P<0.05).
