Background/Aims: Many studies have been performed to find the differences between using epinephrine injection alone and a combination therapy with hemoclip for bleeding peptic ulcer, but the results have been controversial. We retrospectively evaluated the hemostatic efficacy for epinephrine injection alone and injection combined with hemoclip for bleeding peptic ulcers. Methods: Four hundred patients were enrolled. They were assigned to one of the two groups: endoscopic hemostasis with injection of epinephrine (group I, n=156) and combined epinephrine injection with hemoclip (group II, n=244). Results: The continuous bleeding rate was significantly higher in group I than in group II. The recurrent bleeding rate was also significantly higher in group I than in group II. There were no statistical differences in the rates of death, emergency surgery and arterial embolization. The rates of continuous bleeding and the initial failure of hemostasis were higher for the patients with active bleeding on the initial endoscopy irrespective of the applied hemostatic methods. Conclusions: A combination of epinephrine injection and hemoclip is more effective than epinephrine injection alone for treating bleeding peptic ulcers. (Korean J Gastrointest Endosc 2006;32:9-14) 목적: 소화성 궤양 출혈에 대하여 다양한 지혈법이 시도되어 왔으며 그 중에서도 에피네프린 국소 주사와 지혈 클립은 효과적인 지혈법이며 가장 흔히 사용되는 지혈법 중의 하나이다. 지금까지 에피네프린 국소 주사법 단독 치료와 에피네프린 국소 주사에 지혈 클립을 병용한 치료의 효과를 비교한 연구는 많이 있어 왔지만 다양한 결과를 보여 일관된 결론을 내리기 어려웠다. 최근 이 두 가지의 지혈법을 병용함으로써 에피네프린 단독 치료보다 지혈 효과를 증가시킬 수 있다는 보고가 있어 본 연구에서는 이를 확인해 보았다. 대상 및 방법: 2001년부터 2004년까지 경북대학교병원에 상부 위장관 출혈로 내원하여 내시경 검사에서 소화성 궤양 출혈로 진단된 환자 중 에피네프린 국소 주사 단독 치료(그룹 I, 156명)를 받은 환자와 에피네프린 국소 주사와 지혈 클립의 병용 치료를 받은 환자(그룹 II, 244명) 400명을 대상으로 후향적 분석을 하였다. 결과: 영구 지혈률은 병용 치료 그룹에서 에피네프린 단독 치료 그룹보다 높았다(각각 80.7%, 70.5%, p=0.018). 재출혈은 에피네프린 단독 치료 그룹에서 병용 치료 그룹보다 높았다(각각 26.7%, 15.1%, p=0.005). 사망률과 수술이나 동맥 색전술의 빈도에 있어서는 두 그룹 간에 차이가 없었다. 내시경 소견에서 활동성 출혈이 관찰된 경우에는 그렇지 않은 경우보다 초기 지혈 실패율이 높고 영구 지혈률이 낮았다(13.5% vs. 1.4%, p<0.001; 80.7% vs. 65.4%, p=0.001). 결론: 에피네프린 국소 주사와 지혈 클립의 병용 치료는 에피네프린 국소 주사 단독 치료보다 지혈효과가 우수하였다.

A Qualitative Study on the ‘Social Distancing’Experience of University StudentsHyangri Seo & Jaemin Jung Abstract: This study is a study on the experiences of ‘social distancing’ of college students. For this purpose, a total of 10 students were selected, 5 males and females each, from a national university in Seoul, and data were collected through interviews with the participants’ consent. The transcribed material was collected through the five-step process of Colaizzi’s phenomenological research method, with 17 constructed meanings, 6 themes, and 4 themes. Finally, two categories of social distancing, ‘positive life’ and ‘negative life’ derived. Based on the results of this study, the meaning of life of social distancing that college students experience for the first time is presented, and through this, basic data necessary to prepare college students for an effective ‘social distancing’ life through another pandemic is presented.

The purpose of this study is to investigate the effect of career decision self-efficacy on career preparation behavior of male high school athletes. A survey was conducted targeting 149 male athletes in Gyeonggi Province. For data analysis, regression analysis was performed using the statistical program SPSS 25.0. As a result of the analysis, first, career decision self-efficacy of male high school athletes showed a positive correlation with career preparation behavior. Second, it was found that the career decision self-efficacy of male high school athletes had an effect on career preparation behavior. Through this, we intend to provide valuable basic data for the improvement of career decision self-efficacy and career preparation behavior of male high school athletes.

With the rapid development of science and technology and the popularization of information technology, the production environment and manufacturing processes have changed significantly, enterprises increasingly rely on machines and computer control program. The proportion of direct labor costs in the product cost structure has sharply declined, while the proportion of manufacturing cost has increased substantially. With the change of product cost structure, the focus of cost control is gradually shifted from direct material cost and direct labor cost to the manufacturing cost. In order to adapt to the new manufacturing environment, establishing a scientific cost management system has become an inevitable trend. Although the standard cost method provides a cost basis for cost control and performance evaluation, it is not easy to find out the specific link of the cost variance due to too single manufacturing cost distribution standard. Therefore, it is necessary to introduce the basic idea of activity-based costing in the process of setting product standard cost. Based on the activity, the manufacturing cost of the product is allocated by different allocation ratio to ensure the accuracy of product cost accounting. This paper which is based on the standard cost method and activity-based cost method discusses the necessity for the integration of both, and describes its application in Boiler Manufacturing X Co. Ltd. to seek a new cost management model to adapt to the manufacturing environment of modern enterprises. Through the integration of standard cost method and activitybased costing method, the enterprise management goal and the specific production operation are combined to achieve the effective control of product cost.

Arylsulphatase A was purified from the lyophilized extracts of human seminal plasma by using DEAE, P11 cellulose phosphate, and Sephadex G-200 column chromatography. The final preparation of the enzyme was free of β-N-acetylglucosaminidase and β-glucuronidase activities. The partially purified enzyme from the P11 cellulose phosphate column hydrolyzed the dipotassium 2-hydroxy-5-nitrophenyl sulphate with Km and Vmax of 0. 606mM and 12. 66nM/min. respectively. The pH optimum of the enzyme was 4. 4 and temperature optimum was 37℃. The phosphate, sulphate, sulphite, and pyrophosphate ions inhibited the enzyme activity but the silver ion and ascorbic acid activated the enzyme. The chloride ion did not affect arylsulphatase A from human seminal plasma. The molecular weight was estimated to be 100,000 at pH 7.2, and 400,000 at pH 5. 0 by Sephadex G-200 column chromatography.
