This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in rice. In addition, correlation coefficients among yield and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May was large with coefficients of variation(C.V.) of 25.0%, but the variation of the duration of sunshine in May were relative small. No. of panicles per hill and 1,000 grains wt. of brown rice were great with C.V. of 21.1, 19.7%, respectively, brown rice yield show more or less C.V. of 5.5% and milled rice show still less variation. Correlation coefficients between temperatures in period of cultivation from May and yield were positive correlations. Correlation Coefficients between precipitation in period of cultivation from Sep. to Oct. and yield are positive correlations. Correlation coefficients amount the panicle length, no. of panicles, no. of spikelets, ratio of ripened grains, 1,000 grains wt. of brown rice, milled rice yield, brown rice yield and milled rice yield were positively significant at the level of 1 %, respectively.

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

목적: 동측의 대퇴골 경부 골절과 간부 골절이 동반된 경우에서 수술적 치료에 대해 본원에서 실시한 수술 방법들의 결과를 분석하였다. 대상 및 방법: 수술 후 1년 이상 추시 관찰이 가능하였던 11례를 대상으로 하였으며 경부 골절은 Garden 제 1형이 3례, 제 2형이 6례, 제 3형이 1례, 제 4형이 1례였다. 간부 골절은 중간부가 7례, 원위부가 4례였다. 추시 기간은 최소 1년 이상으로 평균 33개월이었고 11례 전부가 남자였으며 나이는 22세에서 54세로 평균 38세였다. 각 수술 방법에 따른 수술시간을 측정하였으며 방사선학으로 골유합의 시기, 부정유합, 불유합 등을 평가하였고 임상적으로는 골절부의 동통 및 관절 운동장애를 평가하였다. 결과: 치료 방법으로는 경부는 다발성 피고정술이 8례, 활강압방 고 나사못고정술이 1례였으며 간부의 경우는 중간부는 역행적 Ender정 고정술이 4례 , 금속판 고정술이 1례, 재건상 골수강내 고정술이 2례, 역행적 금속정 고정술이 1례였고, 원위부는 금속판 고정술이 1례, 역행적 교합성 금속정 고정술이 3례였다. 평균 수술시간은 재건상 골수강내 골종술이 180분, 다발성 핀고정술 및 금속판 고정술이 220분, 다발성 핀고정술 및 역행적 골수강내 고정술이 200분이었다. 골유합 기간은 간부 골절의 경우 평균 5개월이었다. 경부 골절에 대한 합병증으로는 간부 골절에 대해서 Ender정 고정술을 한 1례와 간부에 금속판 고정술을 한 후 지연진단되어 경부에 다발성 핀고정술을 한 1례에서 대퇴골두에 무혈성 괴사증이 병발하였으며 재건상 골수강내 금속정 삽입술을 한 1례에서 수술시 경부 골절의 정복소실이 있었으며 간부 골절에 대한 합병증으로는 역행적 금속정 고정술을 한 2례 (Ender정 1례와 교합성 금속정 1례)에서 불유합이 생겨서 금속판 고정술 및 자가골이식술로 대치하였다. 그리고 Ender정 고정술을 한 1례에서 지속적인 슬관절 주위 동통이 있었다. 결론: 대퇴골 경부 골절과 동측의 간부 골절이 동반된 경우의 수술적 치료에서 재건상 골수강내 금속 고정술은 기술적으로 어려움이 많아서 경부와 간부의 치료를 각각 하는 것이 기술적으로 쉬웠다. 수술시는 경부 골절의 수술을 먼저 하여도 고정에 어려움이 없었으며 간부 골절은 분쇄 골절이 많기 때문에 견고한 내고정이 필요하였다. Purpose: The purpose of this study was to analysis the result of operative treatment in ipsilateral femur neck and shaft fracuture. Material and Methods: Eleven cases of ipsilateral femur neck and shaft fractures were operated and followed more than 1 year. There were 11 men and mean age at index operation was 38 years (range 22~54). In neck fracture there were 3 of type Ⅰ, 6 of type Ⅱ, and 1 of typeⅢ according to Garden classification, shaft fractures were located an middle 1/3 (7 cases), at distal 1/3 (4 cases). We evaluated the operation time, union time, nonunion, malunion, and clinical evaluation with pain and joint stiffness. Result: In neck fractures treatment methods were 8 of multiple pinning, 2 of reconstruction nail and 1 of CHS, in shaft fractures 2 of DCP, 7 of retrograde nailing (3 Ender nail, 4 interlocking nail). The mean operation time was 180 minutes in reconstruction nail, 220 minutes in multiple pinning and DCP and 200 minutes in multiple pinning and retrograde nailing. The mean time for shaft union was 5 months. The complications were 1 case of neck reduction loss during operation in reconstruction nailing group, 1 of persistant pain around knee in Ender nailing group. Conclusion: The author think that reconstruction nail fixation is technically difficult, thus neck and shaft fracture be fixed individually. Neck fracture can be fixed first without difficulty and shaft fractures should be fixed rigidly due to comminution.

Nuss operation is one of the surgical procedure for pectus excavatum and it's method is the insertion of convex steel bar under the sternum through small bilateral thoracic incision. As the patients is growing, the thorax can be compressed gradually by steel bar. So Nuss bar needs to be removed two years after Nuss operation. This study was undertaken to assess the effect on the repiratory mechanics before and after the removal of the Nuss bar. Twenty patients with previous Nuss operation were allocated for the removal of Nuss bar. Lung mechanics (dynamic lung compliance, static lung compliance, and airway resistance), hemodynamic change (heart rate, systolic pressure, and diastolic pressure), and pulmonary gas exchange (arterial oxygen tension, arterial carbon dioxide tension, pulse oximeter saturation, and end tidal carbon dioxide tension) were measured before and after removal of Nuss bar. Respiratory mechanics (dynamic and static lung compliance, inspiratory airway resistance), pulmonary gas exchange and hemodynamic parameter were unchanged before and after the removal of Nuss bar. We concluded that lung mechanics were not changed before and after the removal of Nuss bar in the patients with pectus excavatum and the 95% patients were satisfied with operation.

To investigate the relationship between mucin phenotypes and prognostic factors in gastric adenocarcinoma, immunohistochemical stainings against antibodies(Muc 5AC, Muc-6, Muc-2, CD10, HMG 45M1, and p53 were performed in 104 cases of adenocarcinomas of the stomach. The most frequently expressed mucin phenotype is mixed mucin phenotype, followed by gastric mucin phenotype and intestinal mucin phenotype. In terms of invasiveness and lymph node metastasis, gastric adenocarcinoma with mixed mucin phenotype seems to be more aggressive than those with gastric and intestinal mucin phenotypes. There is no significant difference in expression of p53 protein among three mucin phenotypes. These results suggest that mixed mucin phenotype is the most frequently expressed mucin phenotype in gastric adenocarcinomas and seems to be associated with aggressiveness.
