Resin-modified glass ionomers were introduced in 1988 to overcome the problems of moisture sensitivity and low early mechanical strengths of the conventional glass ionomers, and to maintain their clinical advantages. The purpose of this study was to evaluate the bi-axial fracture strength of four resin-modified glass-ionomers(Fuji II LC, Vitremer, Dyract, VstiGlass), one resin composite material(Z-100), and one conventional glass-ionomer(Fuji II). Three specimens of each material and shade combination were made according to the manufacturers' instructions. Materials were condensed into metal mold with a diameter of 10mm and a thickness of 2.0mm and pressed between two glass plates. Resin-modified glass ionomers were polymerized using a Visilux II light curing unit by irradiating for 60 seconds from both sides, and conventional glass ionomer was cured chemically. After specimens were removed from the molds, surfaces were polished sequentially on wet sandpapers up to No. 699 silicone carbide paper. The specimens were thermocycled for 2,000 cycles between 5℃ and 55℃ distilled water. After thermocycling, bi-axial fracture strengths were measured using a compressive-tensile tester(Zwick 1456 Z020, Germany) with the cross head speed of 0.5mm/minute. The results were as follows: 1. Two factors of the kind and color of materials had a main effect on bi-axial fracture strength (p<0.01), and bi-axial fracture strength was influenced significantly by the kinds of materials (p<0.01). But there was no significant interaction between two variables of the kind and color of materials (p>0.05). 2. Comparing the mechanical properties of the materials, the elastic modulus of Z100 was higher than any other material, and there was no difference in the displacement at fracture among materials. The bi-axial fracture strength of Z100 was significantly higher than any other material, and that of resin-modified glass ionomers was significantly higher than that of conventional glass ionomer (p<0.05). 3. In the same material group, the color of material had little influence on the mechanical properties.

정경희(Kyung Hoi Chung),신승훈(Seung Hoon Shin) 한국사회체육학회 2010 한국사회체육학회지 Vol.0 No.42

This research aims to analyze a priority in the success factors of a mega sports event through the case of `the 2010 ISU Four Continents Figure Skating Championship in Jeonju.` To meet this aim, the Delphi Research method has been adopted for five experts. With this process, the questionnaire has been produced. Visiting during and after the Championship, the pair-wise comparison method (AHP) has been applied to the officers working in the KSU, JSU, JSC and the Jeonbuk Provincial Sports Department. The SPSS WIN Ver. 17.0, Expert Choice 2000 and Microsoft Office Excel 2007 has controlled data processing. The research result is as follows: the priority of the evaluation shows the following order; sports facility condition, efficacy of management, economic value, visitors` satisfaction and general environment condition. After applying composite weight, sports arena management and administration, ripple effect, economic efficiency are high in the priority of success factors while connectivity to other sightseeing sites, cleanness and food are low in evaluation article.

스포츠용품 브랜드 개성의 유형과 그 유형이 소비자ㆍ제품 특성요인에 미치는 영향

정경회(Chung Kyung-Hoi),유광길(Yu Kwang-Kil) 한국스포츠산업경영학회 2006 한국스포츠산업경영학회지 Vol.11 No.1

본 연구는 스포츠 용품 브랜드 개성의 유형과 소비자ㆍ제품 특성요인과의 관계를 알아봄으로써 브랜드 관리를 위한 전략수립을 모색하고자 한다. 본 연구의 대상은 조사목적과 연구범위를 고려하여 전주시에 거주하는 현재 스포츠용품을 사용하는 소비자를 조사대상으로 선정하고, 표본추출은 임의표본추출법을 사용하여 설문조사를 실시하였다. 총 300부의 자기기입식 설문지를 배포하고 수집하여 총 293부를 통계처리 하였다. 분석방법으로 브랜드 개성 항목들 속에 내재해 있는 변인들의 차원을 밝혀내는 데 적합한 주성분 분석을 실시하였다. 측정변인들 간에 내적 일관성 신뢰도(Internal Consistency Reliability)를 확인하기 위해 브랜드 개성 항목, 관여도, 합리성, 제품 친숙도 문항은 Cronbach's α 검증을 실시하였다. 브랜드 개성이 소비자ㆍ제품 특성요인에 미치는 영향을 파악하기 위하여, 변수 선택법으로는 Stepwise를 이용하였고, 선형회귀분석을 실시하였다. 본 연구의 실증분석 결과를 요약하면 다음과 같다. 스포츠용품 소비자가 인식하는 브랜드 개성은 ‘활동’, ‘예절’, ‘진실’, ‘다정’으로 나타났고 전체 설명 값은 76.456%로 나타났다. 활동이 주요인으로 추출되었다는 것은 스포츠라는 상품의 속성을 반영한 결과로 여겨지며, 예절이 스포츠 용품 브랜드 개성에 설정되었다는 것은 한국의 정서가 반영된 결과라 생각되어 진다. 브랜드 개성이 소비자ㆍ제품 특성요인에 미치는 영향은 관여도에는 ‘활동’과 ‘다정’이 큰 영향을 미치는 것으로 나타났다. 즉 활동요인과 다정요인이 높을수록 관여도가 높아진다고 할 수 있다. 【관여도 = 3.385 + 0.173 × 활동 + 0.172 × 다정】이라는 통계적으로 유의미한 회귀모형(p=0.000)이 설정되었다. 합리성에는 ‘활동’과 ‘진실’이 큰 영향을 미치는 것으로 나타났다. 즉 활동요인과 다정요인이 높을수록 합리성이 높아진다고 할 수 있다. 【합리성 =3.723 + 0.167 × 활동 + 0.131 × 진실】이라는 통계적으로 유의미한 회귀모형(p=0.000)이 설정되었다. 제품 친숙도에는 ‘다정’이 큰 영향을 미치는 것으로 나타났다. 즉, 브랜드의 다정요인은 소비자의 합리성에 유의하게 영향을 미친다고 볼 수 있다. 【제품 친숙도 = 3.358 + 0.214 × 다정】이라는 통계적으로 유의미한 회귀모형(p=0.000)이 설정되었다. Under the modern environment of enterprise it is very difficult to deal with dynamic change of market environment using conventional market strategies such as a differentiation of markets, goods, and prices due to the fierce competition among enterprise. As a result, many of those companies have shown their interests in the strategic management of brand Many of the world's leading brands have made a great effort in order to maintain the loving support from their customers. In other words, a brand has gained the momentum as a main element of competitive advantage over other competitors. Therefore, to attain a dominant position in a brand over other foreign companies, it is very crucial for domestic companies to make every endeavor to increase the monetary value of a brand and manage it. Especially, in terms of the domestic market of sport goods which has been dominated by foreign brands such as Nike or Adidas, the importance of the strategic management of brands has become apparent. As mentioned above, today, brands take up a huge part of companies' success, furthermore, the images of brands take a great roll as a sub-part of brands. Today, according to the consumer behavior theory, a brand characteristic has been highlighted and empathized by companies to distinguish their own brands form others'. Modern consumers tend to express themselves through brands, furthermore, they even identify themselves as specific brands. Above all, the strategic management of a brand is most important factor in order to manage a brand systematically. The following section is the summary of results of practical analysis of the study. The personalities of sports brands that consumers recognize appear to be activity, courtesy, sincerity, and tenderness. As for the effect which is caused by brand characteristics onto consumer-goods traits, activity and tenderness showed interrelation, and, tenderness showed correlation in product-familiarity.

Preparation of C/C composites by the chemical vapor infiltration (CVI) of propane pyrolysis

Kyung-Hoon Bang,Gui-Yung Chung,Hyung-Hoi Koo 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.1

The preparation of C/C composites by the chemical vapor infiltration (CVI) of the pyrolysis carbon from propane was studied. Pyrolysis carbon was deposited at 30 torr and at temperatures between 1,173 and 1,233 K. The rate of carbon deposition increased slightly with time. The main gas products in the exit gas were methane, ethylene,and acetylene. The fraction of ethylene decreased and that of acetylene increased with the reaction temperature and the propane concentration. The produced propyl radicals reacted further at a high temperature and at a high propane concentration. These trends were similar to those of the reported data. Changes of the shapes of deposited carbon in the pores of preform were confirmed with SEM photos. The mathematical modeling of the system with the deposition rate constant from the reference estimated experimental data well.
