熱處理한 ferrite matrix의 球狀黑鉛鑄鐵에서 黑鉛의 크기가 2㎜∼4㎜(100배, 以下 동일함) 程度의 경우의, 이것이 機械的 性質 즉 引張强度, 降伏强度, 伸率, 斷面收縮率, 硬度 등에 미치는 영향에 대해서 다각도로 조사 검토하여 다음과 같은 결과를 얻었다. (1) 球狀黑鉛의 크기가 커짐에 따라서 引張强度는 珪素量이 3.0% 以下에서는 직선적으로 다소의 감소를 나타내며 珪素가 3.0%에서 3.3% 程度까지는 변화가 없다. 사용 珪素量이 1.8%인 경우는 黑鉛의 크기가 0.1㎜ 커짐에 따라 引張强度는 0.4kg/㎟程度 감소한다. (2) 球狀黑鉛의 크기가 커짐에 따라 伸率은 증가한다. 珪素量이 1.8%인 경우는 黑鉛의 크기가 0.1㎜ 커짐에 따라 伸率은 0.5%程度 증가한다. (3) 同一한 基地組織과 同一한 組成을 갖는 球狀黑鉛鑄鐵의 硬度는 黑鉛의 크기에 無關하며 珪素量 1.8% 인 경우 硬度는 H_B 로 148 程度이다. In the spheroidal graphite cast iron, the effects of graphite size were studied on the mechanical properties such as tensile strength, yield strength, elongation, reduction of area and hardness. The important results obtained are as follows. 1. As the graphite size increased, the tensile strength decreased lineally little by little in case of less than 3.0% of Si and varied little in case of 3.0% and 3.3% of Si. For example, with 0.1㎜ increase of the graphite size in case of 1.8% of Si, the tensile strength decreased as much as 0.4 kg/㎟. 2. The elongation incresed in proportion the increase of graphite size. For example, with 0.1㎜ increase of the graphite size, the elongation increased as much as 0.5% in case of 1.8% of Si. 3. The graphite size did not influence the hardness of the spheroidal graphite cast iron which had the same matrix structure and composition and the Brinell hardness was about 148 in case of 1.8% of Si.

Ureteral obstruction due to appendicitis or its complications is rare in adults. We present a fifty-five year old women who showed the right-sided hydronephrosis and hydroureter on intravenous pyelography without urinary symptoms. At exploratory laparatomy, the cause for this was found to be severe inflammatory adhesions on the right mid-ureter by retrocecal appendicitis. Follow-up intravenous pyelography after appendetomy revealed complete disappearance of preoperative hydronephrosis and hydroureter.

Background/Aims: Clarithromycin resistance is a main factor for treatment failure in the context of Helicobacter pylori infection. However, the treatment regimen for clarithromycin-resistant H. pylori infection has not yet been determined. We aimed to compare the efficacy and cost-effectiveness of 14-day bismuth-based quadruple therapy versus 14-day metronidazole-intensified triple therapy for clarithromycin-resistant H. pylori infection with genotypic resistance. Methods: This was a multicenter, randomized, controlled trial. A total of 782 patients with H. pylori infection examined using sequencing-based clarithromycin resistance point mutation tests were recruited between December 2018 and October 2020 in four institutions in Korea. Patients with significant point mutations (A2142G, A2142C, A2143G, A2143C, and A2144G) were randomly assigned to receive either 14-day bismuth-based quadruple therapy (n=102) or 14-day metronidazole-intensified triple therapy (n=99). Results: The overall genotypic clarithromycin resistance rate was 25.7% according to the sequencing method. The eradication rate of 14-day bismuth-based quadruple therapy was not significantly different in the intention-to-treat analysis (80.4% vs 69.7%, p=0.079), but was significantly higher than that of 14-day metronidazole-intensified triple therapy in the per-protocol analysis (95.1% vs 76.4%, p=0.001). There were no significant differences in the incidence of side effects. In addition, the 14-day bismuth-based quadruple therapy was more cost-effective than the 14-day metronidazole-intensified triple therapy. Conclusions: Fourteen-day bismuth-based quadruple therapy showed comparable efficacy with 14-day metronidazole-intensified triple therapy, and it was more cost-effective in the context of clarithromycin-resistant H. pylori infection.
