임병훈,송영택,정재희,Yim, Byung-Hun,Song, Young-Tack,Chung, Jae-Hee 대한소아외과학회 2008 소아외과 Vol.14 No.2

To evaluate the long-term prognosis of biliary atresia after Kasai operation, a total of 14 patients (of the 41 patients operated upon from 1982 to 1997), who had been followed up for more than 10 years, were included in this retrospective study. Eleven out of 14 patients survived with their native livers, and their data analyzed for age at operation, clearing time of jaundice, histological outcome, postoperative complications, effectiveness after the application of an intussusception anti-reflex valve, and quality of life. Average age at surgery was 62.8 days. Serum bilirubin was normalized within three months in all patients. Six among the eleven long-term survivors had ascending cholangitis as one of the postoperative complications. The application of an intussusception anti-reflux valve did not show any statistical significance in long-term survival. Most of long-term survivors appeared to enjoy good quality of life. Kasai operation might not be the definitive treatment for biliary atresia; however, Kasai operation made it possible to achieve long-term survival for patients with biliary atresia when the patients were detected and treated as early as possible.

The purpose of this study is to investigate the behavior and ductility of reinforced high-strength concrete beams using fly ash artificial lightweight aggregate. All of 10 specimens have the same cross sectional dimensions (180mm×220mm×2790mm) and are tested in condition of simply supported beam under an two-point loading. Five reinforced high-strength lightweight concrete beams and five reinforced high-strength normal concrete beams with different tensile reinforcement ratio () were tested to investigate their behavior. Test results indicate that the ratio of flexural strength between experimental results and those by ACI 318 is 1.00 in case of normal concrete beams and 1.01 in case of lightweight concrete beams. The reinforced high-strength concrete beams using fly ash artificial lightweight aggregate behave more brittly than high-strength normal concrete beams with equal reinforced ratio after maximum strength. When concrete compressive strength is 40MPa in reinforced high-strength lightweight concrete beams, the ratio of longitudinal reinforcement to balanced reinforcement needs to be limited to 0.5 in order to obtain 3 in ductility factor. 본 실험연구는 석탄회 인공경량골재를 사용한 고강도콘크리트 보의 거동 및 연성을 규명하기 위해 수행하였다. 10개의 시험체 크기는 모두 180mm×220mm×2790mm이며 단순 지지상태에서 2점 가력하였다. 석탄회 인공경량골재를 사용한 고강도콘크리트 보 5개와 천연골재를 사용한 고강도콘크리트 보 5개는 다른 인장철근비 비율()로 보강되었다. 실험결과 휨강도는 ACI 318 기준에 의한 계산값 대비 천연골재를 사용한 시험체의 경우 1.00, 석탄회 인공경량골재를 사용한 시험체의 경우 1.01의 값을 보였다. 석탄회 인공경량골재를 사용한 시험체가 보통골재를 사용한 시험체보다 취성적인 거동을 보이는 것으로 나타났다. ACI 규준은 석탄회 인공경량골재를 사용하고 콘크리트강도가 40MPa일 경우 콘크리트 보의 연성지수 3을 확보하기 위해 인장철근비 비율을 0.5 이하로 제한되어야 할 것으로 판단된다.

임병훈 우송대학교 2000 우송대학교 논문집 Vol.5 No.-

The purpose of this study is to verify the waterproofing properties of membrane coating to the Autoclaved Lightweight Concrete (ALC). ALC have basically high water absorbtion and low strength in its physical properties. These properties incite several types of troubles. In these study three kinds of experiment, those are watertight test, adhesion test and application test, are executed. It can be concluded as follows (1) Water content rate of ALC is not related to the performance of membrane coatings. (2) Membrane coatings, which is composed of epoxy resin, is inferior to another resin coating. And so it is necessary that epoxy resin coating is attend to use on the ALC material. (3) It is clear that synthetic resin except epoxy is superior to waterproofing properties such as flow and hardness of coating material.

가전제품의 주요 국가 간 제품품질 경쟁력 비교에 관한 연구

임병훈,엄기홍 한국기업경영학회 2012 기업경영연구 Vol.19 No.3

본 논문은 특정 산업 또는 제품 수준에서 품질경쟁력 수준을 측정할 수 있는 평가모형을 개발하고, 이를 국가별로 비교하려는 시도로, 한국표준협회와 산업연구원(2007)에서 개발한 품질경쟁력 모형을 기반으로 실증적으로 적용 가능한 모형을 개발하였다. 이를 위해 먼저 국가간 경쟁력을 비교하는 WEF의 국가경쟁력 평가 모형, Global Manufacturing Competitiveness Index, 국가산업의 품질경쟁력 수준지수, 한국사용품질지수 (KS-QEI)를 포함하는 6개 경쟁력지수 모형을 비교, 시사점을 도출하였다. 또한 품질을 구성하는 다양한 요소들을 기업과 사용자 측면에서 검토하고, 경쟁력 평가의 대상을 최종 제품만이 아니라 제품을 생산하는 기업의 내부적 요인과 국가의 인프라 수준 등을 반영하여 모형을 구축하였다. 도출된 모형은 5개 국가(한국, 미국, 일본, 독일, 중국)에서 생산되는 4개의 주요 생활가전제품(TV, 냉장고, 세탁기, 에어컨)을 대상으로 일반 소비자와 전문가를 대상으로 설문조사와 2차 자료 조사를 통해 품질경쟁력 수준을 평가하였다. 연구 결과, 전반적으로 중국을 제외한 비교 대상 국가들 간의 차이는 크지 않은 것으로 나타났으며, 한국제품의 품질경쟁력은 기술선진국들로 알려진 독일, 일본, 미국 제품들에 근접한 품질경쟁력을 갖는 것으로 나타났다. 현재 한국의 생활가전제품에 대한 사용자평가는 다른 선진국가들과 큰 차이가 없이 개선되어졌으나 가전제품 전문가들의 인식과 평가는 아직 개선되지 않은 것으로 나타났다. 특히, 전문가 평가가 중심을 이루는 생산품질과 경영품질 부분에서 상대적인 평가가 낮게 나타났다 This study tries to develop a practically applicable product quality competitiveness model based on the model by Korean Standards Association and Korea Institute for Industrial Economics and Trade (2007). For this, 6 models comparing product quality or competitiveness across diverse countries including WEF, Business Competitiveness Index, Global Manufacturing Competitiveness Index, KS-QEI and National Design Competition Power Index are reviewed. Based on the review, an evaluation model that measures quality competitiveness of products or particular industries among countries is developed. Here, quality competitiveness is defined, as shown in <Table 1>, to include four dimensions, design quality, production quality, usage quality, and management quality. It is also designed to incorporate various factors which constitute quality dimension in the area of both firms and consumers. Finally, variables for both end-products, internal factors of manufacturers, and the infrastructure of a country are included in the model as variables of competitiveness level. The model is applied to 4 major home appliances (TV, refrigerator, washing machine, air conditioner)among 5 countries (Korea, US, Japan, Germany, China). For this, 3 types of data are collected and analyzed. First, consumer survey of 1,200 respondents with product usage experience is performed using online research firms. Secondly, online survey targeting experts in consumer electronics is implemented using the expert panel of research firms in each of 5 countries. Relative importance of 4 quality dimensions is measured and calculated based on the AHP method from experts survey. Thirdly, secondly data for market share and the number of patents are collected for each product and country. Based on the AHP evaluation by experts, relative weight of four quality dimensions is calculated. For all product categories, usage quality is found to be the most important factor, followed by production quality. Results of this study show that except China, no significant difference in quality exists among the evaluated countries. The quality competitiveness score of Korean products is 67.3 and is similar to Germany (69.0), Japan (68.5), and US (67.8), which are known to have high reputation for quality competitiveness. The score of China is found to be low at 60.9. However, in the evaluation by experts, the gap between Korea and other developed countries is larger. Among 4 quality dimensions, usage quality is found to be very high for Korean products, followed by design and production quality. Out of 4 product categories surveyed, the quality of Korean TV is evaluated highest, second to Japan. For AC, the quality of Korean products is ranked as second with US and Japan. The evaluation for Korean refrigerator and washing machine is relatively lower compared to other countries.
