본 연구는 부산의 16개 자치구 중 해운대구를 대상으로 브랜드 슬로건의 이미지 요인이 브랜드 연상 및 태도와 어떤 관계를 가지는 지를 분석함으로서 표적시장의 잠재고객에게 지역을 효과적으로 알릴 수 있는 브랜드 슬로건의 개발과 평가에 대한 실증적 연구를 수행하였다. 본 연구의 결과는 다음과 같다. 첫째, 브랜드 슬로건 이미지 평가항목의 타당성과 측정항목의 신뢰도를 검증하였다. 브랜드 슬로건 이미지 요인의 타당성 분석결과 친밀성, 차별성, 의미성 및 이해가능성의 네 개 요인으로 묶여졌다. 신뢰도 분석 결과 Cronbach의 α 계수는 모두 0.8 이상을 나타내어 측정척도는 신뢰할 수 있었다. 둘째, 브랜드 슬로건 이미지가 브랜드 연상 및 태도에 영향을 미치는 과정에서 지역친숙도, 지역인지도 및 브랜드 슬로건 인지도의 조절변수가 어떤 영향을 미치는지를 조절회귀분석을 이용하여 분석하였다. 연상을 종속변수로 하고 지역친숙도와 조절변수의 상호작용 효과를 검증한 결과 1%의 유의수준에서 모두 유의한 결과를 나타내었다. 지역인지도의 상호작용 효과검증 결과 조절변수인 의미성이 1% 수준에서 조절효과가 있었다. 브랜드 인지도의 상호작용효과 검증 결과 의미성×브랜드 인지도는 1% 수준, 차별성×브랜드 인지도는 5% 수준에서 통계적으로 유의하였다. 태도를 종속변수로 하고 브랜드 슬로건 이미지 항목들과 지역친숙도의 상호작용 효과를 검증한 결과 태도에 미치는 영향은 의미성×지역친숙도만이 5% 수준에서 음(-)의 영향을 미치는 것으로 나타났다. 브랜드 슬로건 이미지 항목들과 지역인지도의 상호작용항이 태도에 미치는 영향은 의미성×지역인지도만이 5% 수준에서 유의하였으며, 음(-)의 영향을 미쳤다. 브랜드 슬로건 이미지 항목들과 브랜드 인지도의 태도에 대한 영향은 의미성×브랜드인지도는 1%, 차별성×브랜드 인지도는 5%, 친밀성×브랜드인지도는 10% 수준에서 유의하였다. 이와 같은 연구결과는 도시 브랜드 전반에 대한 브랜드 슬로건 이미지의 전략적 방향을 제시하는 데 크게 기여할 것으로 기대된다. Urban managers need to have as much knowledge as possible on all dimensions that affect the city, in order to make informed decisions and draw up a good city plan. To create healthy communities and to understand the costs and benefits of different of different development patterns, they need to know the present city image, to then design the image that they want to get and define the actions to improve it. The study of the city image is important part of diagnostic for the city`s strategic planning process. The objective of this study is to define the brand slogan and find out components of it. In addition, the study focused on relations among components of brand equity of brand slogan adopting the concept of brand equity. Literature review indicates that few studies have been conducted in the korea and oversea for this subject. Final purpose of the study is to analyze recognition or attitude toward a autonomous district as a moderator variable in the relation among the components of a brand slogan. Frequency analysis, ANOVA, reliability analysis, validity analysis, factor analysis, moderated regression analysis were used. The results are as follows; The brand slogan image was divided into four factors as a result of exploratory factor analysis. Brand slogan image influences on brand association and brand attitude. Therefore, findings of this study could be utilized a fundamental guide line for a brand slogan`s development. However, this study is exploratory in nature. Thus more studies which elaborate various aspects of research design are expected.

Antineoplastic activity against human gastric and colon carcinoma cell lines was tested in eighty-three species of Korean plants including Korean medicinal plants which have been frequently used in oriental herb prescriptions. The plant materials were extracted with methanol and the cytotoxic activity was tested using a calorimetric tetrazolium assay (MTT assay). Twenty-six plant extracts against gastric carcinoma cell line, eighteen extracts against colon carcinoma cell line and fourteen plant extracts against both carcinoma cell lines showed antineoplastic activity at the concentration of less than $100{\mu}g/ml$. The effective components from four species have been isolated and reported.

Air pollutants nitrogen oxides are inevitably generated in the combustion reaction. Its amount trend is steadily increasing because the rapid modern industrialization and population growth. For this reason, NOx is controlled to reducing the harmful components in the exhaust gas. So Marine Environment Protection Committee (MEPC) take effect ‘Tier I’, ‘Tier II’ of air pollution regulation in 2005 and 2011 respectively. According to NOx emissions are strictly regulated management of the vessel through them. In addition, since 2016 the regulation enter into force in the next step ‘Tier III’ was confirmed by MEPC 66th committee. It``s 80% enhanced emissions limits than the ‘Tier I’ Alternatively these emission regulation, research is actively being carried out about exhaust gas after-treatment methods through the vessel application of Selective Catalytic Reduction(SCR). Therefore depending on the basic specification of cell density according to the Area velocity, Space velocity, Linear velocity is studied the effects of NOx removal efficiency

WO₃ 첨가에 의한 TiO₂계 SCR 촉매의 상전이 및 입자성장이 고온안정성에 미치는 영향

윤상현,김장훈,신병길,박삼식,신동우,이희수,Yoon, Sang-Hyeon,Kim, Jang-Hoon,Shin, Byeong-Kil,Park, Sam-Sik,Shin, Dong-Woo,Lee, Hee-Soo 한국결정성장학회 2011 韓國結晶成長學會誌 Vol.21 No.4

$WO_3$ 첨가가 $TiO_2$계 SCR 촉매의 고온안정성에 미치는 영향을 구조적, 형상학적 분석을 통해 규명하였다. 순수한 $TiO_2$시편과 10 wt%의 $WO_3$를 첨가한 $WO_3-TiO_2$ 시편을 제조하여 $800^{\circ}C$에서 5시간 동안 열적 스트레스를 인가하였다. FT-IR을 이용하여 촉매의 산점 변화를 확언한 결과 $WO_3-TiO_2$ 시편의 경우가 순수한 $TiO_2$ 시편에 비해 열적 열화로 인한 산점의 감소가 상대적으로 적었다. 반면 $WO_3-TiO_2$ 와 $TiO_2$의 anatase에 서 rutile로의 상전이 정도는 각각 28.4%와 22.9%로 오히려 $WO_3-TiO_2$ 시편에서 rutile 상이 더 많이 증가한 것을 확인하였다. 형상학적 분석 결과 $WO_3-TiO_2$ 시편은 고온에서 $TiO_2$에 고용되어 있던 amorphous 상태의 $WO_3$가 $TiO_2$ 입자 표면에 석출되며 결정화가 일어나게 되고 이로 인해 촉매의 입자성장을 억제함을 확인하였다. 따라서 SCR용 $TiO_2$ 촉매에 첨가된 $WO_3$는 anatase에서 rutile로의 상전이를 촉진시켜 고온에서의 촉매 활성을 저하시킬 수 있지만, 입성장 억제에 대한 영향이 커 결과적으로 고온안정성을 향상시킴을 확인하였다. Thermal stability of the $TiO_2$ SCR catalyst with W03 loading was investigated in terms of structural and morphological analyses. The $TiO_2$ catalysts with 10 w% $WO_3$ content and without $WO_3$ were prepared. which were heat-treated at $800^{\circ}C$ for 5 h. It was found that the catalytic acidity was decreased by thermal degradation in the $WO_3-TiO_2$ specimen that relatively less than the $TiO_2$ specimen from FT-IR analysis. The phase transition of the $TiO_2$ catalyst from anatase to rutile was increased by heal-treatment, and the percentage of the rutile phase was 28.4 % in the $WO_3-TiO_2$ and 22.9 % in the $TiO_2$. A shell region of $WO_3$ distinguished from a $TiO_2$ particle was also observed in the grain boundary region, and the $WO_3$ led to the suppression of grain growth. It could be confirmed that the suppression of grain growth can contribute to the improvement of catalytic properties for thermal stability more than the increase of anatase-rutile phase transformation which cause the reduction of the catalytic activity in the $TiO_2$ SCR catalyst by the presence of $WO_3$.

본 연구에서는 plate-type의 V₂O₅-WO₃/TiO₂ SCR 촉매의 열적 비활성화 특성을 고찰하였다. 이를 위하여 plate type의 촉매를 500~800 ℃의 온도에서 3 h 동안 열처리하였다. 촉매의 특성 변화를 고찰하기 위하여 XRD, N₂ adsorption-desorption에 의한 비표면적과 기공특성, SEM-EDS 등을 측정하였으며, 열처리 온도에 따른 NOx 전환율을 측정하였다. NOx 전환율은 열처리 온도가 증가함에 따라 감소하였는데 700 ℃ 이상인 경우에 크게 감소하였다. 이는 TiO₂의 결정상이 anatase에서 rutile로 변하고, TiO₂의 입성장 및 CaWO₄와 같은 결정상이 생성되어 촉매의 비표면적과 기공부피가 감소하였기 때문이다. 또한 700 ℃ 이상의 온도에서는 촉매 활성물질인 V₂O₅가 승화/기화되었으며, 촉매의 담지체로 사용되는 금속 지지체는 Cr 탄화물 형성에 따른 입계 부식과 산화가 발생하는 것으로 나타났다. In the present paper, the thermal deactivation characteristics of plate-type commercial V₂O₅-WO₃/TiO₂ SCR catalyst were investigated. For this purpose, the plate-type catalyst was calcined at different temperatures ranging from 500 ℃ to 800 ℃ for 3 hours. Structural and morphological changes were characterized byXRD, specific surface area, porosity, SEM-EDS and also NOx conversion with ammonia according to the calcine temperature. The NOx conversion decreased with increasing calcine temperature, especially when the catalysts were calcined at temperatures above 700 ℃. This is because the crystal phase of TiO₂ changed from anatase to rutile, and the TiO₂ grain growth and CaWO₄ crystal phase were formed, which reduced the specific surface area and pore volume. In addition, V₂O₅, which is a catalytically active material, was sublimated or vaporized over 700 ℃, and a metal mesh used as a support of the catalyst occurred intergranular corrosion and oxidation due to the formation of Cr carbide.
