BACKGROUND Studies have revealed that Children's psychological,behavioral,and emotional problems are easily influenced by the family environment.In recent years,the family structure in China has undergone significant changes,with more families having two or three children.AIM To explore the relationship between emotional behavior and parental job stress in only preschool and non-only preschool children.METHODS Children aged 3-6 in kindergartens in four main urban areas of Shijiazhuang were selected by stratified sampling for a questionnaire and divided into only and nononly child groups.Their emotional behaviors and parental pressure were compared.Only and non-only children were paired in a 1:1 ratio by class and age(difference less than or equal to 6 months),and the matched data were compared.The relationship between children's emotional behavior and parents'job stress before and after matching was analyzed.RESULTS Before matching,the mother's occupation,children's personality characteristics,and children's rearing patterns differed between the groups(P<0.05).After matching 550 pairs,differences in the children's parenting styles remained.There were significant differences in children's gender and parents'attitudes toward children between the two groups.The Strengths and Difficulties Questionnaire(SDQ)scores of children in the only child group and the Parenting Stress Index-Short Form(PSI-SF)scores of parents were significantly lower than those in the non-only child group(P<0.05).Pearson’s correlation analysis showed that after matching,there was a positive correlation between children's parenting style and parents'attitudes toward their children(r=0.096,P<0.01),and the PSI-SF score was positively correlated with children's gender,parents'attitudes toward their children,and SDQ scores(r=0.077,0.193,0.172,0.222).CONCLUSION Preschool children's emotional behavior and parental pressure were significantly higher in multi-child families.Parental pressure in differently structured families was associated with many factors,and preschool children's emotional behavior was positively correlated with parental pressure. 展开更多

As an important branch of literature, children's literature is exerting a pivotal role in social education. From the perspec-tive of reception aesthetics, English version of Cao Wenxuan's work Bronze and Sunflower is studied from four aspects:horizon of expectation, indeterminacy, aesthetic distance and fusion of horizons. In reception aesthetics, target readers-children are the center of the reading. So translation methods are to satisfy children's demand. It has also been found out that there are some features for children's literature translation include using colloquial words, concise sentence structure and the combination of domestication and foreignization. 展开更多

BACKGROUND Patient satisfaction with facial appearance at the end of orthodontic camouflage treatment is very important, especially for skeletal malocclusion. This case report highlights the importance of the treatment plan for a patient initially treated with four-premolar-extraction camouflage, despite indications for orthognathic surgery.CASE SUMMARY A 23-year-old male sought treatment complaining about his unsatisfactory facial appearance. His maxillary first premolars and mandibular second premolars had been extracted, and a fixed appliance had been used to retract his anterior teeth for two years without improvement. He had a convex profile, a gummy smile, lip incompetence, inadequate maxillary incisor inclination, and almost a class I molar relationship. Cephalometric analysis showed severe skeletal class Ⅱ malocclusion(A point-nasion-B point = 11.5°) with a retrognathic mandible(sella-nasion-B point = 75.9°), a protruded maxilla(sella-nasion-A point = 87.4°), and vertical maxillary excess(upper incisor to palatal plane = 33.2 mm). The excessive lingual inclination of the maxillary incisors(upper incisor to nasion-A point line =-5.5°)was due to previous treatment attempts to compensate for the skeletal class Ⅱ malocclusion. The patient was successfully retreated with decompensating orthodontic treatment combined with orthognathic surgery. The maxillary incisors were repositioned and proclined in the alveolar bone, the overjet was increased, and a space was created for orthognathic surgery, including maxillary impaction, anterior maxillary back-setting, and bilateral sagittal split ramus osteotomy to correct his skeletal anteroposterior discrepancy. Gingival display was reduced, and lip competence was restored. In addition, the results remained stable after 2 years. The patient was satisfied with his new profile as well as with the functional malocclusion at the end of treatment.CONCLUSION This case report provides orthodontists a good example of how to treat an adult with severe skeletal class Ⅱ malocclusion with vertical maxillary excess after an unsatisfactory orthodontic camouflage treatment. Orthodontic and orthognathic treatment can significantly correct a patient’s facial appearance. 展开更多

Purpose The paper shows the interpretive impact of different constructions of the point of view available to the reader/viewer in book and animated movie versions of a children's picture book,a novel for pre-adolescents/early teenagers,and a graphic novel for adolescents and adults.Design/Approach/Methods Excerpts from book and animated movie versions of the same story are compared using multimodal analysis of interpersonal meaning to show how the reader/viewer is positioned in relation to the characters in each version,complemented by analyses of ideational meaning to show the effect of point of view on interpretive possibilities.Findings Focusing mainly on multimodal construction of point of view,the analyses show how interpretive possibilities of ostensibly the same story are significantly reconfigured in animated adaptations compared with book versions even when the verbal narrative remains substantially unchanged.Originality/Value The study shows that it is crucial to students’critical appreciation of,and their creative contribution to,their evolving digital literary culture that in this new era of educational technology,attention in literacy and literary education focuses on developing understandings of digital multimodal narrative art,and that animated movie adaptations are not presented pedagogically as isomorphic with,or simply adjunct to,corresponding book versions. 展开更多
