Objective: Seoul City has implemented the Safe Pharmacy in 2013. This study aimed to ascertain the success factors of the smoking cessation service of the Safe Pharmacy. Methods: The data for the smoking cessation registration cards were obtained from the pharmacies which participated in 2014 Safe Pharmacy. The sample included 289 smokers in 6 districts who participated at least one sessions of smoking cessation service. the service included both behavioral intervention and nicotine replacement therapy. In order to identify the effectiveness of the smoking cessation service, logistic regression analysis was used. The dependent variable was the success of quitting smoking at the 4th week. The independent variables included age, sex, employment, chronic disease, district, smoking amount, registration path, supporters for quitting smoking and number of service sessions. Results: Fifty eight point eight percent of the sample successfully quit smoking at the 4th week. Unemployment, higher smoking amount, and less service sessions were negatively related to the success of quitting smoking. There were differences in the success rate across districts. Age, sex, chronic disease, registration path, and anti-smoking supporters were not related to the success rate. Conclusion: Pharmacy can be an effective community resource for smoking cessation. Factors that could increase the effectiveness of smoking cessation service of the Safe Pharmacy and possible ways to enhance the participation of pharmacies in smoking cessation services were also discussed.

Twelve patients underwent surgical interventions for aortic aneurysms consecutively from September 1986 to September 1990 in the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. They were all men ranging in age from 25 to 68 years with the mean age of 48 years. Five patients of them had aneurysms involving ascending aorta, one aneurysm involving both ascending and descending aorta, four aneurysms involving descending thoracic aorta, and the others had aneurysms involving abdominal aorta. According to morphological classification, six cases of them were in dissection and the others in fusiform aneurysms. All the cases were pathologically true aneurysms and four of them were in acute status. According to causal classification, seven patients of them had atherosclerosis, three cystic medial necrosis, and the others had syphilis and trauma respectively. Six patients with ascending aortic aneurysm had annuloaortic ectasia with aortic regurgitation and underwent ascending aortic graft and aortic valve replacement[Bentall`s operation]. The others with descending thoracic and abdominal aortic aneurysms underwent Dacron graft replacement. Both hemorrhage necessitating reopening of the chest and wound dehiscence were observed in three patients and hoarseness in one patient. Cerebrovascular accident occurred three and a quarter years postoperatively in one patient and he died two days later. The others were followed up via OPD and have been doing well postoperatively.

The paper presents the experimental investigations into the effect of ground granulated blast furnace slag (GGBFS) on the time-dependent tensile strength of concrete. The splitting and flexural tensile strength of concrete was determined at the ages of 3, 7, 28, 56, 90, 150 and 180 days using the cylindrical and prism specimens respectively for plain and GGBFS concrete. The amount of cement replacement by GGBFS was 0%, 40% and 60% on the weight basis. The maximum curing age was kept as 28 days. The results showed that the splitting and flexural tensile strength of concrete containing GGBFS has been found lower than the plain concrete at all ages and for all mixes. The tensile strength of 40 percent replacement has been found higher than the 60 percent at all ages and for all mixes. The rate of gain of splitting and flexural tensile strength of 40 percent GGBFS concrete is found higher than the plain concrete and 60 percent GGBFS concrete at the ages varying from 28 to 180 days. The experimental results of time-dependent tensile strength of concrete are compared with the available models. New models for the prediction of time-dependent splitting and flexural tensile strength of concrete containing GGBFS are proposed. The present experimental and analytical study will be helpful for the designers to know the time-dependent tensile properties of GGBFS concrete to meet the design requirements of liquid retaining reinforced and pre-stressed concrete structures.

Experimental investigation was undertaken to determine early-age strength development and the relationships between the mechanical properties of type I, V and V/fly ash cement concrete with different curing temperature. The tests for mechanical properties, i.e., compressive strength, splitting tensile strength and modulus of elasticity were carried out for type, I, V and V with 15% replacement with fly ash cement concrete. For this purpose 480 concrete cylinders cured at isothermal conditions of 10, 23, 35 and 5$0^{\circ}C$ were tested at ages of 1, 3, 7 and 28days. According to the experiments, the concrete subjected to high temperature at early age got greater strength at early age, however eventually lower strength at late age. The derived relationships between compressive strength and splitting tensile strength and elastic modulus of elasticity appeared to be identical for all types of cement.

Prolapse of the aortic valve is the main cause of insufficiency of the aortic valve as a complication of ventricular septal defect. Aortic insufficiency gets worse by the progress of prolapse of aortic valve due to lack of support of the valve and the hemodynamic effect of blood flow through the ventricular septal defect. This produces typical clinical picture, that may be serious and threatening when it is untreated. Type and timing for the surgical treatment of the ventricular septal defect with aortic insufficiency is considered. Among 113 ventricular septal defect, 9 patients of ventricular septal defect with associated aortic insufficiency were experienced from June. 1983 to June 1988 at the Department of Thoracic and Cardiovascular Surgery, Chon-Buk University Hospital. Male was 6 patients and female was 3 patients. Ages were from 7 years to 24years. 5 patients were from 10 to 19 years age. 3 patients were below 10 years age. The ratio of pulmonary blood flow to systemic f low [Qp/Qs] was 1.53 and in pulmonary vascular resistance, normal or slight increase was 7 patients, moderate 1 patient, and severe 1 patient. Ventricular septal defect was subpulmonic in 5 patients and infracristal in 4 patients. Prolapse of right coronary cusp was 7 patients, right and non coronary cusp 1 patient and non coronary cusp 1 patient. Teflon patch closure of ventricular septal defect was undertaken in 3 patients and primary closure in 1 patient. Among the 4 patients of defect closure alone, one patient performed valve replacement 7 months later due to progressive regurgitation and cardiac failure and the result was good. The other 3 patients were good result. Closure of ventricular septal defect and aortic valvuloplasty performed in 4 patients. 2 patients of these required valve replacement for the sudden intractable cardiac failure and died due to low cardiac output. The cause of intractable cardiac failure was tearing of repaired valve at the fixed site. The other 2 patients were good result. Closure of ventricular septal defect and valve replacement performed in 1 patient with good result.

Purpose: Continuous renal replacement therapy (CRRT) has become the preferred dialysis method to support critically ill children and neonates with acute kidney injury. Using CRRT on neonates has increased, but reports about experience are limited. The aim of this study is to describe the clinical application, outcomes, and complications of CRRT in children and neonates. Methods: A retrospective review was performed in 135 children and 36 neonates who underwent CRRT at a tertiary hospital from 2008 to 2015. Results: At the initiation of CRRT, the median age of children was 72 months and the corrected age of neonates was 37.1 weeks. Median body weight of neonates was 3.2 kg. In neonates, initial degree of fluid overload [FO%], blood flow rate [BFR] and ultrafiltration rate [UFR] rate during CRRT were higher than in children. Median real time of CRRT was 90.5 and 53.5 hours in children and neonates, respectively. Downtime of CRRT was 0.7 and 1.3 hours/day. Median mortality rates (44.4% vs.47.2%) and complication rates were similar between the groups. Conclusion: CRRT can be used for a wide range of critically ill children and neonates. Different application methods of CRRT can contribute to increased survival of neonates.

본 연구에서는 산업부산물인 TDFA를 혼입한 콘크리트에 대하여 초기재령의 공학적 특성을 분석하였다. 물-결합재비 0.5, FA 치환율 20%인 콘크리트를 대상으로 TDFA를 3~12%치환하여 경화 전 및 경화 후의 특성을 분석하였다. TDFA 혼입율 6% 이후의 배합에서는 작업성이 현저하게 감소하였고 공기량 확보가 어려웠으며, 이로 인해 감수제 및 공기연행제를 추가하여 작업성을 개선시켰다. TDFA 혼입율 6~12%까지는 콘크리트의 강도에 큰 영향은 없었으며, 탄산화저항성 및 염해저항성에서는 FA 20% 치환 배합보다 우수한 성능을 나타내었다. 그러나 공기량이 부족한 TDFA 혼입율 6%배합에서는 동결융해 저항성이 크게 감소하였다. 공기량 및 작업성이 확보된다면 FA를 12%수준까지 TDFA로 치환해도 공학적인 성능을 확보할 수 있을 것으로 판단된다.
