온라인 쇼핑몰에서의 리뷰 속성이 브랜드 태도, 구매결정 및 온라인 구전의도에 미치는 영향

김준성,Kim, Joon-Sung 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.7

본 연구는 온라인 쇼핑몰에서 리뷰의 속성을 평점, 댓글의 양 및 이미지정보로 분류하여 브랜드 태도와 구매결정 및 온라인 구전의도에 미치는 영향을 검증하였다. SPSS 23.0을 이용하여 빈도분석, 요인분석, 회귀분석 등을 실시하였다. 분석 결과, 리뷰 속성이 브랜드 태도, 구매결정 및 온라인 구전의도에 정(+)의 영향을 미치는 것이 확인되었으나 댓글의 양은 구매결정에 영향을 미치지 않은 것으로 나타났다. 브랜드 태도는 구매결정에, 온라인 구전의도에 정(+)의 영향을 미치는 것이 확인되었다. 더불어 평점, 이미지정보와 구매결정 간의 영향관계에서, 또한 리뷰 속성과 온라인 구전의도 간의 영향관계에서 브랜드 태도의 매개효과가 확인되었다. 이와 같은 결과는 소비자가 무조건 댓글의 양이 많은 것을 선호하지 않으며, 리뷰를 작성할 때 최대한 높은 평점과 포토후기에 초점을 맞출 수 있도록 해야 함을 시사한다. This study classifies review attributes into ratings, number of comments and image information in online shopping mall to verify their impact on brand attitude and purchase decision and e-WOM intention. Use SPSS 23.0 for frequency analysis, factor analysis and regression analysis. The results showed that review attributes have a positive effect on brand attitudes, purchase decision and e-WOM intention, but the number of comments has not affect on purchase decision. Brand attitude has a positive effect on purchase decision and e-WOM intention. Brand attitude has media effect in the relationship between ratings, image information and purchase decision, and in the relationship between review attributes and e-WOM intention. As these results, consumers don't always like to have a lot of comments. and should allow to focus on high ratings and photo reviews as much as possible when writing reviews.

상부 위장관 출혈

김준성,Kim, Joon Sung 대한소아소화기영양학회 2008 Pediatric gastroenterology, hepatology & nutrition Vol.11 No.suppl2

소아에서의 급성 상부 위장관 출혈은 흔하지는 않지만 잠재적으로 심각한 위험을 초래할 수 있는 문제이다. 상부 위장관 출혈의 원인은 환아의 연령에 따라 다양하기 때문에 소아 환자를 평가할 때는 각 연령대 별로 흔한 특정 원인들을 미리 염두에 두는 것이 필요하다. 환자의 상태가 위중할 때는 신속한 병력 청취와 활력 징후 측정, 정맥 확보 및 특정 검사 등이 빠른 시간내에 이루어지는 것이 중요하다. 응급 상황에서는 기도 확보, 호흡, 순환 등 초기 심폐소생술을 먼저 시행한 후에 자세한 병력 청취, 신체 검사와 함께 상부 위장관 출혈을 일으킨 기저 질환을 확인하기 위하여 더 자세한 특수한 진단적 검사 등이 필요하고, 이를 근거로 각각의 원인에 따른 적절한 치료가 시행되어야 한다. Upper gastrointestinal bleeding (UGIB) is defined as bleeding in the gastrointestinal tract where the source of bleeding is proximal to the ligament of Treitz. UGIB is uncommon, but a potentially serious lifethreatening problem in children. The clinical manifestation of UGIB in children ranges from asymptomatic microcytic anemia to hypovolemic shock. As the etiology of UGIB varies with age, it is important to be aware of the specific etiologies at different ages when assessing children with UGIB. It is imperative that each child with UGIB be evaluated carefully, including an assessment of the patient's cardiorespiratory status along with other diagnostic studies for determining the underlying cause of bleeding.

궤양성 대장염에 동반된 간정맥 혈전증 1예

Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.

The data mainly used for the model are as follows: the personal information, the information of insurance product, etc. With the data, we suggest three types of models: content-based filtering model, collaborative filtering model and classification models-based model. The content-based filtering model finds the cosine of the angle between the users and items, and recommends items based on the cosine similarity; however, before finding the cosine similarity, we divide into several groups by their features. Segmentation is executed by K-means clustering algorithm and manually operated algorithm. The collaborative filtering model uses interactions that users have with items. The classification models-based model uses decision tree and random forest classifier to recommend items. According to the results of the research, the contents-based filtering model provides the best result. Since the model recommends the item based on the demographic and user features, it indicates that demographic and user features are keys to offer more appropriate items.

Lesch-Nyhan syndrome is an X-linked recessive disorder characterized by hyperuricemia, choreoathetosis, spasticity, mental retardation, and compulsive, self-injurious behavior. This disorder results from a complete deficiency of the purine salvage enzyme, hypoxanthine-guanine phosphoribosyl transferase(HPRT). We report here on a case of Lesch-Nyhan syndrome in a 1-year, 7-month-old male who presented with frequent vomiting, failure to thrive, and developmental delay. The diagnostic work-up revealed hyperuricemia, hyperuricosuria, and medullary nephrolithiasis. The HPRT activity in the erythrocytes was undetectable with a biochemical assay. We also identified de novo mutation which was a deletion of the 649th base, adenosine, in HPRT gene(649delA) by analysis of cDNA using RT-PCR technique coupled with direct sequencing.

Crohn`s disease and ulcerative colitis are well known risk factors of intestinal cancer in relation to the extent and duration of disease. Rarely, small bowel cancer can develop after a longstanding inflammation of Crohn`s disease with a relatively higher incidence than the general population. Signet ring cell carcinoma is a rare condition among intestinal cancers, and the diagnosis or detection is more difficult if the cancer originates from the small bowel. We report a case of a 30-year old female in whom signet ring cell carcinoma of ileum was diagnosed after a 15-year history of Crohn`s disease. (Korean J Gastroenterol 2007;50:51-55)

I explicate the standard theory of probabilistic causation and the average theory of probabilistic causation and define the relation between the two theories. I also eliminate the ambiguity of causal claims by explicating the two theories. First, I introduce the two theories and discussions about them. Second, I explicate the relation between the two theories in detail and reveal the case in which the standard theory helps an agent make a rational decision. Third, I argue that the standard theory does not render the Surgeon General`s warning about hazards of smoking meaningless. Fourth, I point out that the average theory is too limited to guide agents` many different decisions.
