A total of 30 cases of the peptic ulcer in children, who underwent operations from January 1981 to December 1995 because of complications at Department of the Surgery, Chonbuk National University Medical School, is reviewed. Twenty-three were males (76.7%), 7 females (23.3%) and male was preponderant at 3.3:1. There were 25 cases (83.3%) age 10 to 15 years, 3(10.0%) between 2 and 9 years, and 2 (6.7%) below 2. The ulcer was located at duodenum in 27(90.0%), and at stomach in 3 cases (10.0%). Complications were perforation in 19 cases (63.3%), pyloric obstruction in 9 (30.0%) and bleeding in 2 (6.7%). For perforation, truncal vagotomy with pyloroplasty was done in 11 cases, truncal vagotomy with hemigastrectomy and gastrojejunostomy in 6, and simple closure in 2 cases. For obstruction, truncal vagotomy with hemigastrectomy and gastrojejunostomy was done in 5, and truncal vagotomy and pyloroplasty in 3 cases. For bleeding lesions, truncal vagotomy and pyloroplasty was performed in 2 cases. Ten postoperative complications developed in 9 patients: adhesive ileus in 5, recurrence in 2, pneumonia 2, and wound seroma 1 case. One patient developed a primary duodenal perforation and another a recurrent obstruction. Both of patients had symptoms for more than 3 years and were treated with truncal vagotomy and pyloroplasty for the primary operations. Hospital stay was 11.5 days for the patient with perforated ulcer, 11.0 days for the patient with pyloric obstruction, and 14.5 days for the child with bleeding. Average hospital period was 11.6 days. To reduce recurrences after operation, extensive procedure such as distal gastrectomy with vagotomy at the first operation should be considered in case with severe complication or with patients who have been symptomatic for long periods.

수도(水稻)의 생육(生育)과 수량(收量)에 미치는 볏짚과 규회석(珪灰石)의 효과(效果)를 규명코져 볏짚은 무시용(無施用)과 88g/pot(1000kg/10a)로 2수준, 규회석(珪灰石)은 무시용(無施用)(50ppm), 27(150ppm), 85(300ppm), 135g/pot(450ppm조절량) 4수준을 각각 다르게 처리하고 pot 시험(試驗)을 한 결과(結果)는 다음과 같다. 1. 볏짚이나 규회석(珪灰石) 단용(單用)을 수도(水稻)의 초기생육(初期生育)을 억제(抑制)시켰으나 이들의 병용구(倂用區)에서 이상적인 초형(草型)으로 발달(發達)되어 특히 최고분운기(最高分芸期) 이후(以後)에 효과(效果)가 매우 커서 정조수량(正租收量)이 증가(增加)되었다. 2. 볏짚 무시용구(無施用區)는 규회석(珪灰石) 27g/pot구(區)에서 모두 정조수량(正租收量)이 많았고 볏짚 시용구(施用區)에서는 시용당년(施用當年)에는 규회석(珪灰石) 85g/pot구(區), 그리고 다음해의 잔효구(殘效區)에서는 규회석(珪灰石) 135g/pot구(區)에서 정조수량(正租收量)이 가장 많아 볏짚시용(施用)은 규산(硅酸)의 요구량(要求量)을 증가(增加)시키는 것으로 나타났다. 3. 처리간(處理間)에 최고수량(最高收量)을 낸 구(區)는 시비년도(施肥年度)에는 볏짚+규회석(珪灰石) 85g/pot구(區)로서 대조구(對照區)보다 25%의 정조수량(正租收量)이 증대(增大)되었다. 볏짚과 규회석(珪灰石)의 잔효(殘效)를 본 익년도(翌年度)에서는 볏짚+규회석(珪灰石) 135g/pot구(區)가 대조구(對照區)보다 30%의 증가(增加)를 보여 볏짚이나 규회석(珪灰石) 단용(單用)보다 병용효과(倂用效果)가 컸었다. This study was conducted to find out the effect of rice straw and wollastonite applied to the paddy soil on the growth and yield of the rice plant. The soil was treated with two level of straw 0 and 88gr per pot, of which respectively combined with 4 levels of wollastonite, 0 (Avail $SiO_2$: 50 ppm), 27 (Avail. $SiO_2$: 150 ppm), 85 (Avail. $SiO_2$: 300 ppm) and 185 (Avail. $SiO_2$: 450 ppm) gr per pot. The results for two years experiment were as follows. 1. Application of rice straw and wollastonite, respectively, suppressed the growth of the plant at early stage. As a consequence the hight and number of tiller of the plant were comparatively smaller, but the combined effect of rice straw and wollastonite treatment on the plant growth appeared after the maximum tillering stage and got a better yield as compared with single treatment of rice straw or wollastonite. 2. At the pot of no rice straw and 27 gr wollastonite treatment, and also pot of rice straw and 85gr (in the year of 1983 experiment) as well as 135gr wollastonite treatment (in the year 1984 experiment), the yield of total dry material and unhulled rice of the plant were respectively higher than other pots in different treatment and the plant height showed similar tentency. Application of rice straw in paddy soil appeared to require more wollastonite for growth of the rice plant as compared with no rice straw application. 3. The highest yield was obtained at the pot with rice straw and 85gr of wollastonite treatment in the year of 1983 experiment, were its yield had 25% increament as compared with the control pot, while being studied for residual effect of rice straw and wollastonite application in the next year, the highest yield was obtained at the pot with rice straw and 135gr wollastonite treatment, where its yield had 30% increament as compared with the control pot.

음식물쓰레기 퇴비 시용이 담수 조건의 벼 생육과 수량, 체내 양이온 균형 및 토양의 Na 집적 등에 미치는 영향을 밝히고자 폿트 실험을 하였다. 처리로는 무처리, NPK, NPK에 NaCl을 3수준(300, 600, $900kgha^{-1}$)으로 시용한 처리, 음식물쓰레기 퇴비와 돈분발효 퇴비를 각각 3수준(30, 60, $90Mgha^{-1}$)으로 한 처리 등을 두었다. 음식물쓰레기 퇴비는 $Na_2O$ 함량이 2.2%로 높았다. 이앙 직후 활착기간 중 음식물쓰레기 퇴비 $40Mgha^{-1}$ > NPK+NaCl $900kgha^{-1}$ > 음식물쓰레기 퇴비 $20Mgha^{-1}$ 순으로 심한 위조 현상을 보였으며, 그 원인으로 판단되는 토양용액 중의 EC와 유기산 함량이 음식물쓰레기 되비 $40Mgha^{-1}$ 처리에서 매우 높았다. NaCl을 $900kgha^{-1}$까지 시용하여도 대조구인 NPK구에 비하여 유의성 있는 수확기 건물중의 감소가 일어나지 않았다. 음식물쓰레기 퇴비 시용은 시용량에 관계없이 수확기 건물중을 감소시킨 반면, 돈분발효퇴비는 $40Mgha^{-1}$까지 시용량이 증가될수록 건물중을 증가시켰다. NPK + NaCl처리들과 음식물쓰레기 퇴비 처리들에서 Na 시용량이 증가될수록 수확기 식물체 중 Na 함량이 직선적으로 증가되었다. Na 당량비도 Na 함량과 같은 경향이었으며, Na 당량비와 K 당량비 사이에는 고도의 유의성있는 부의 상관관계를 보였다. Na와 K의 당량비 및 Na/K 당량비 비율은 처리간 편차가 매우 컸던 반면, Na+K 당량비 합은 편차가 적어 상당부분 Na의 K에 대한 생리적 대체가 인정되었다. Na 이용률은 NaCl과 음식물쓰레기 퇴비 처리들에서 12~22%를 나타내었다. High sodium contents in food-waste compost(FWC) is the greatest limitation to recycle it to arable lands in Korea. The effects of the FWC application to paddy soil on the growth of rice plants, cationic balance in plants, and the sodicity of soil have been studied in pot trials. The effects of FWC application were compared with those of NaCl compound and swine manure compost(SMC) application. $Na_2O$ contents of FWC were high as 2.2%. Immediately after transplanting, rice plants in three treatments showed severe wilting in the order of 40Mg FWC $ha^{-1}$ > NPK+900kg $NaClha^{-1}$ > 20Mg FWC $ha^{-1}$. The high EC value and volatile acid contents of soil solution were regarded as the cause of severe wilting of young rice plants. Increase of NaCl application rate upto $900kgha^{-1}$ showed no significant reduction of dry matter yield at harvesting stage. Regardless of application rates FWC reduced the dry matter yield at harvesting stage, while SMC increased it with increase of application rates upto $40Mgha^{-1}$. In NPK+NaCl and FWC treatments, Na contents and equivalent ratio in plants increased linearly with increase of Na application rates. Between Na and K equivalent ratio negative correlation with high significance was shown. In contrast to much difference of Na, K, and Na/K equivalent ratio among treatments, little difference of Na+K indicated the physiological substitution of Na for K in rice plants. Na use efficiency in NPK+NaCl and FWC treatments showed 12-22%.
