먹거리 地域祝祭에서의 飮食購買行動에 대한 계획된 行動理論적용: 사전지식의 역할
조태영 청운대학교 관광산업연구소 2011 관광산업연구 Vol.5 No.2
This study was implemented to present implications in terms of marketing to sponsors of local food festivals by investigating behavioral patterns of tourists visiting a local food festival on purchasing foods based on theory of planned behavior. Results and implication of the study were summarized as follows:First, by implementing factor analyses, the following factors were drawn: attitude,subjective norm, recognized behavioral control, and prior knowledge. Second, as feasibility analysis of the final model showed some incompatibilities in some indices, the model was modified by applying corrective indices and obtained the following values: χ2=436.017(p=.000),df=230, Q=1.896, GFI=.894, AGFI=.861, RMR=.048, NFI=.907, TLI=.944, CFI=.953, and RMSEA=.055. As these values showed that the model could satisfy the general evaluation criteria of structural equation, it seems that the model was valid. Third, Assumption 1: “Attitude will exert significant impacts on behavioral intention” was rejected. Fourth,Assumption 2: “Subjective norm will exert significant impacts on behavioral intention” was accepted. Fifth, Assumption 3: “Recognized behavioral control will exert significant impacts on behavioral intention” was accepted. Sixth, Assumption 4: “Recognized behavioral control will exert significant impacts on behavior” was accepted. Seventh, Assumption 5: “Prior knowledge will exert significant impacts on behavioral intention” was rejected. Eighth,Assumption 6: “Prior knowledge will exert significant impacts on behavior” was rejected. Ninth, Assumption 7: “Behavioral intention will exert significant impacts on behavior” was accepted.

This study presents distribution of carbonic anhydrase (CA) isozymes Ⅳ and Ⅸ, membrane associated forms, and CA Ⅰ and Ⅱ, cytoplasmic forms, in rat parotid and submandibular glands using Western blot analysis and immunohistochemical staining. Western blot analysis demonstrated that CAs Ⅰ, Ⅱand Ⅸ were found to be abundantly expressed, but CA Ⅳ was weakly expressed in parotid gland. Submandibular gland expressed abundant CAs Ⅰ and Ⅱ, weak CA Ⅸ, and undetectable level of CA Ⅳ. In hematoxylin-eosin staining, parotid gland was entirely composed of serous acini and their ducts while submandibular gland was mixed population of serous and mucous lobules. Most of lobules (submandibular gland proper type) contained mostly serous acini and their ducts with granular convoluted duct. Some lobules (sublingual gland type) contained mostly mucous acini with serous demilune and their ducts without granular convoluted duct. In parotid gland, CAs Ⅳ and Ⅸ were immunolocalized in duct cells and not in serous acinar cells. Immunoreactivity for CAs Ⅰ and Ⅱ was also detectable in duct cells. Serous acinar cells were positive for CA Ⅱ, and negative for CA Ⅰ. In submandibular gland, CAs Ⅳ and Ⅸ were immunolocalized in duct cells but not in acinar cells of both types of lobules. Immunoreactivity for CAs Ⅰand Ⅱ was also detectable in duct cells of both types of lobules. Cells of serous acini and serous demilune were positive for CA Ⅱ, and negative for CA Ⅰ. Mucous cells were negative for both CAs Ⅰ and Ⅱ. These results demonstrate the distribution of CA isoenzymes in parotid and submandibular glands of the rat, and suggest CAs Ⅳ and Ⅸ as well as CAs Ⅰ and Ⅱ are related to electrolytes metabolism of saliva in duct cells. 침샘에서 carbonic anhydrase (CA) 동위효소의 발현 여부를 관찰하고자 흰쥐 귀밑샘과 턱밑샘을 대상으로 CAs Ⅰ, Ⅱ, Ⅳ 및 Ⅸ 동위효소에 대한 항체를 사용하여 면역조직화학 염색을 시행하였고, 이들 조직에서 각각의 CA 동위효소 단백발현을 Western blot 분석을 시행하여 확인하였다. Western blot 분석 결과 귀밑샘은 CAs Ⅰ, Ⅱ와 Ⅸ는 강하게 발현되었고 CA Ⅳ는 미약하게 발현되었다. 턱밑샘에서는 CAs Ⅰ과 Ⅱ는 강하게 발현되었으나 Ca Ⅸ는 미약하게 발현되었고 CA Ⅳ는 발현되지 않았다. H-E 염색에서 귀밑샘은 장액샘꽈리와 도관으로 구성되어 있었으며 턱밑샘은 샘의 대부분을 차지하는 고유턱밑샘형 소엽과 점액샘꽈리와 장액반달로 구성된 혀밑샘형 소엽으로 되어 있었다. 면역조직화학 염색에서 귀밑샘은 CA Ⅳ, Ⅸ 및 Ⅰ의 반응은 사이관, 줄무늬관 및 소엽사이관 같은 도관세포에서 양성을 보이고 샘꽈리세포에서는 음성이었다. CA Ⅱ 반응은 도관세포와 샘꽈리세포에서 양성이었다. 턱밑샘의 고유턱밑샘형 소엽에서 CA Ⅳ, Ⅸ 및 Ⅰ의 반응은 도관세포에서는 양성반응을 보였으나 샘꽈리세포에서는 음성이었다. CA Ⅱ 반응은 도관세포와 장액샘꽈리세포에서 모두 양성이었다. 턱밑샘의 혀밑샘형 소엽에서 CAs Ⅳ, Ⅸ 및 Ⅰ 반응은 도관세포에서는 양성을 보였으나 샘꽈리세포에서는 음성이었다. CA Ⅱ 반응은 도관세포와 장액반달세포에서 양성이었으나 점액샘꽈리세포에서는 음성이었다. 이상의 관찰로 흰쥐 귀밑샘과 턱밑샘에 분포하는 CA 동위효소의 분포를 확인하였으며, 침 도관세포에서의 전해질 대사는 CAs Ⅰ과 Ⅱ뿐 아니라 CAs Ⅳ와 Ⅸ도 관여할 것으로 추측되었다.
