  • 경제규모가 확대됨에 따라 전력, 통신, 가스 등 각종 사회 간접시설물이 지하에 매설되고 있으며 그 규모나 범위도 해마다 증대하고 있다. 이러한 지하매설관은 무질서하게 난립하고 관리되지 않아 사고가 빈번하게 발생하며 효율적인 지하공간을 운영할 수 없는 실정이다. 지하시설에 대한 정확한 정보 파악은 안전뿐만 아니라 공사진행에 있어서 필수적인 사항이라 할 수 있겠다. (중략)

  • Gastrointestinal stromal tumor (GIST) is a mesenchymal tumor derived from Cajal cells originating from the myotonic plexus. The expression of tyrosine kinase (KIT) membrane receptors that are active on KIT is inhibited by the KIT inhibitor imatinib mesylate. GISTs are resistant to conventional chemotherapy, and radiation therapy is not significantly beneficial for GISTs. With the development of imatinib mesylate, approximately 81.6% of patients with advanced and metastatic GIST exhibit an effect above the stabilization response, thereby increasing the survival time. However, imatinib mesylate alone is unlikely to cure metastatic GISTs. Even with a partial or stable response, imatinib mesylate may be used for a longer time period. However, resection of grossly visible lesions should be considered for patients with a stable response during surgical treatment. In this study, we present a case of GIST with liver metastasis after imatinib mesylate treatment, which was followed up without recurrence after partial resection.

The Impact of CSV on Brand Image and Consumers' Behavioral Intentions: Focussing on CSV Intentionality and Company -Consumer Identification (기업의 CSV활동이 브랜드 이미지와 소비자행동의도에 미치는 영향 : CSV의도성과 기업 -소비자 동일시를 중심으로)

  • This study examined the causal relationship between CSV and brand image and consumers' behavioral intentions by structural equation model using psychological variables such as CSV intentionality and company-consumer identification. 198 questionnaires were used to test 8 hypotheses using Smart PLS 2.0. Results are as follows: First, two hypotheses were rejected that CSV had a negative effect on CSV intentionality and CSV intentionality had a negative effect on brand image. Second, CSV has a positive effect on company-consumer identification and company-consumer identification has a positive effect on brand image, purchase intention, and willingness to pay. This study suggests the necessity of enhancing customer participation and communication for the company to establish CSV strategies.
