A study was made of the effects of alloying elements on microstructural factors and fracture properties of five high speed steel (HSS) rolls. Particular emphasis was placed on the role of hard carbides located along solidification cell boundary and the type of the martensite matrix. Microstructural observation, X-ray diffraction analysis, hardness and fracture toughness measurement, and fractographic observation were conducted on the rolls. Various types of carbides mostly segregated in the cell-boundary regions were dependent upon the type and amount of alloying elements, and played an important role in hardness and fracture toughness due to their high hardness. The effects of alloying elements were analyzed on the basis of the liquidus surface diagram, and indicated that the proper contents of carbon equivalent, tungsten equivalent, and vanadium were 1.9∼2.0%, 10∼11%, and 5∼6%, respectively. The roll containing a small amount of cell-boundary carbides and lath-type tempered martensite matrix had excellent fracture toughness since carbides were well spaced. For a better microstructure and fracture properties of the HSS rolls, therefore, it was suggested that the optimization of alloying elements was required to achieve the homogeneous distribution of carbides.

한류가 국가이미지, 한국관광 및 웨딩관광 행동의도에 미치는 영향
김창규,김기동,최혜정 동북아관광학회 2015 동북아관광연구 Vol.11 No.4
본 연구의 목적은 방한 중국이 한국웨딩을 경험 한 후 한류관여도, 국가이미지, 한국관광 및 웨딩관광 행동의도에 영향을 미치는 영향요인을 규명하는데 있다. 분석결과, 한류관여도가 웨딩관광행동의도에 영향을 미치는 요인으로 나타났다. 하지만 한류관여도는 한국의 국가이미지에는 영향을 미치지 않는 것으로 나타났다. 한국의 국가이미지는 웨딩관광행동의도에 영향을 미치는 것으로 나타났지만, 한국관광 행동의도에는 영향을 미치지 않는 것으로 나타났다. 한국관광 행동의도는 방한 웨딩관광행동에 영향을 미치지 않는 요인으로 나타났다. 결론적으로 중국인의 한류관여도는 한국의 국가이미지와 웨딩관광행동의도를 예측하는 변수로 적합하다고 볼 수 있다. 즉 중국인의 한류관여도는 한국의 국가이미지와방한 웨딩관광을 의도에 긍정적인 영향을 미치는 요인으로 보인다고 할 수 있다. 본 연구는 기존의 한류와 국가이미지, 관광행동의도와의 관계에서 웨딩관광행동의도를 더욱 관심있게 다루었다. 하지만 웨딩관광 행동의도는 방한 관광행동의도에 내포적으로 포함될 수 있다는 측면에 있어서 논리적 연계성에 대한 한계점을 가지고 있다. The purpose of this study was to investigate the influencing factors that affect the Korea's national image, the Intention of Korea tourism and wedding tourism after wedding tourism behavior experienced wedding targeting Chinese wedding tourists. The results are as follows: Hanllu involvement affect Korea's national image, Korea tourism behavior and wedding behavior. The result of verification is the impact on the tourism behavior of wedding appeared as a factor affecting the degree of involvement wedding Korean tourist behavior. However, Hanllu involvement was found in the national image of Korea, which had no affect. The national image of Korea appear to affect behavior in wedding tourism, tourism in South Korea has also showed behavior that has no affect. The degree of the Korea tourism actions as a factor does not affect behavior winter wedding tourism. In conclusion, it can be seen that Chinese Hanllu involvement of the appropriate parameters as Korea's national image and also to predict the behavior of wedding tourism. This study also addressed the enabling of more interested in Korea's traditional image, weddings acted in relation to the help given by tourist action. Also wedding tourist behavior has limitations for logical linkages in terms of being able to implicitly included also a visit to the tourist act.

액상/기상중 전기선 폭발법을 이용한 은 나노유체의 제조 및 특성평가에 관한 연구
김창규,이경자,이창규,Kim, Chang-Kyu,Lee, Gyoung-Ja,Rhee, Chang-Kyu 한국재료학회 2009 한국재료학회지 Vol.19 No.9
The silver nanofluids were synthesized by the pulsed wire evaporation (PWE) method in a liquid-gas mixture. The size and microstructure of nanoparticles in the deionized water were investigated by a particle size analyzer (PSA), transmission electron microscope (TEM), and scanning electron microscope (SEM). Also, the synthesized nanofluids were investigated in order to assess the stability of dispersion of nanofluid by the zetapotential analyzer and dispersion stability analyzer. The results showed that the spherical silver nanoparticle formed in the deionized water and mean particle size was about 50 nm. Also, when explosion times were in the range of 20$\sim$200 times, the absolute value of zeta potential was less than -27 mV and the dispersion stability characteristic of low concentration silver nanofluid was better than the high concentration silver nanofluid by turbiscan.
