Purpose: We aimed to analyze the frequency of eosinophilia-associated diseases and to search for possible markers that may be useful for their differential diagnosis. Methods: We retrospectively reviewed the medical records of 148 patients with peripheral blood eosinophil count of more than 500/μL who visited the Allergy Department of Chonnam National University Hospital for the first time from January to December 2016. Blood eosinophilia was categorized as mild (<1,500/μL), moderate (1,500–5,000/μL), and severe (>5,000/μL). Results: Blood eosinophilia was mostly caused by allergic diseases (41.9%), parasitic infestation (23.6%), and drug allergy (19.6%). Eosinophil count was higher in patients with parasitic infestation (P<0.01), drug allergy (P<0.01), hypereosinophilic syndrome (HES, P<0.001), or eosinophilic granulomatosis with polyangiitis (EGPA, P<0.001) than in those with allergic diseases. The eosinophilic cationic protein level was higher in patients with HES than in those with allergic diseases (P<0.05) and parasitic infestation (P<0.05). The total IgE level was lower in patients with HES than in those with parasitic infestation (P<0.05) and EGPA (P<0.05). The vitamin B12 level was higher in patients with HES than in those with parasitic infestation (P<0.05). There was no statistically significant difference in tryptase levels between the groups. The most common cause of mild eosinophilia was allergic diseases (59.8%), followed by parasitic infestation (22.7%) and drug allergy (13.4%). The common causes of moderate eosinophilia were drug allergy (37.8%), parasitic infestation (29.7%), and allergic diseases (10.8%). The common causes of severe eosinophilia were EGPA (28.6%), HES (21.4%), parasitic infestation (14.3%), and drug allergy (14.3%). Conclusion: Common causes of blood eosinophilia in patients who visit the allergy department are allergic diseases, parasitic infestation, and drug allergy. Several markers, including eosinophil count, total IgE, and vitamin B12, may be useful for the differential diagnosis of eosinophilia-associated diseases.
스마트교육 환경에서 학습자의 미디어 리터러시, 자기조절학습능력, 협력지향성이 초등학생의 인지된 학업성취에 미치는 영향

본 연구는 스마트교육 환경에서 초등학생의 인지된 학업성취에 영향을 미치는 학습자 특성을 파악하기 위하여 기존에 학업성취에 영향을 미치는 것으로 알려졌던 변인 중 스마트교육 환경의 특징을 반영할 수 있는 학습자 특성으로 미디어 리터러시, 자기조절학습능력, 협력지향성을 선정하였다. 연구 결과 본 연구에서 선택된 독립변인은 모두 초등학생의 인지된 학업성취와 영향관계를 갖는 것으로 나타났으며, 기여도는 자기조절학습능력, 미디어 리터러시, 협력지향성 순이었다. 변인별로 분석한 결과 미디어 리터러시 영역에서는 스마트기기 활용 능력, 자아표현, 비판적 이해, 자기조절학습능력에서는 자기조절 영역이 선택되었다. 협력지향성은 초등학생의 인지된 학업성취에 영향을 주는 요인으로 밝혀졌으나 다른 요인과 달리 부적인 관계를 갖는 것으로 나타났다. 본 연구의 시사점은 다음과 같다. 첫째, 스마트교육 환경에서 학업성취를 높이 기 위해서는 학습자의 자기조절 능력을 증대하기 위한 환경을 조성할 필요가 있다. 둘째, 스마트교육 환경에서는 고차원적 사고 능력을 증진하기 위한 새로운 학습전략의 개발이 필요하다. 셋째, 스마트기기 사용에 관한 정의적 접근이 포함된 교육이 실시되어야 한다. 넷째, 학습자가 수업에서 자연스럽게 미디어 리터러시 능력을 키울 수 있도록 창의적 수업 전개가 필요하다. 마지막으로 스마트교육 환경에 맞는 새로운 평가 체계가 구축될 필요가 있다.

This study attempted to investigate the influence of quality of human services quality by eyelash experts on consumers’ switching costs and willingness to pay and analyze the mediating effects of service satisfaction. For this, a survey was performed against a total of 392 young adult women in their 20s who had eyelash treatment in Seoul and Gyeonggi-do, and data were collected using measuring instruments. The collected data were analyzed by normality testing, confirmatory factor analysis, correlation analysis and structural equation modeling (SEM). In addition, mediating effects were examined, using bootstrapping, and the results found the followings: First, human service quality had a positive influence on service satisfaction with statistical significance so that Hypothesis 1. was supported. Second, human service quality revealed a positive effect on willingness to pay with statistical significance so that Hypothesis 2. was accepted. Third, human service quality showed no statistically significant influence on switching costs so that Hypothesis 3. was rejected. Fourth, service satisfaction had a positive effect on willingness to pay with statistical significance so that Hypothesis 4. was supported. Fifth, service satisfaction revealed a negative influence on switching costs with statistical significance so that Hypothesis 5. was adopted. Sixth, service satisfaction showed a partial mediating effect in the influence of human service quality on willingness to pay so that Hypothesis 6. was accepted. Seventh, service satisfaction revealed a full mediating effect in the influence of human service quality on switching costs so that Hypothesis 7. was supported. .
