The respiratory function is relevant to the craniofacial growth and orthodontic diagnosis. The size of the pharyngeal airway was measured in lateral cephalometric view in children visited Kyung Hee University Hospital from January 2015 to August 2017. A total of 74 healthy children (36 boys and 38 girls) aged 7 - 11 years (mean, 8.5 years) with a normodivergent facial pattern were divided into three groups according to anteroposterior jaw relation measuring A point-Nasion-B point (ANB) angle. Lateral cephalometric data were used to measure the airway dimensions. The dimensions of the middle airway were significantly lower, reducing the upper airway space, in large ANB angle group than in other children, suggesting that children with large ANB angle have narrower airway space than others. 본 연구는 소아에서 상하악의 전후방적인 골격적 위치 관계에 따른 기도의 너비를 평가하고자 하였다. 2015년부터 2017년 8월31일까지 경희대학교 치과병원 소아치과에 내원하여 측모두부방사선사진을 촬영한 소아 중 정상적인 안면골격의 수직적 성장 양상을 보이는 7세부터 11세(평균연령 8.5세) 어린이 74명(남아 36명, 여아 38명)을 A point-Nasion-B point (ANB) 각도에 따라 세 군으로 나누어 측모두부방사선사진 계측을 통해 기도 너비를 비교평가하였다. 중기도너비, 하기도너비 및 기능적교합평면상에서의 기도너비에서 통계적으로 유의한 차이를 보였으며, 큰 ANB각도를 지니는 군이 다른 군보다 기도너비가 더 작은 것으로 나타났다. 따라서 골격성 2급 부정교합을 지닌 소아들이 1급이나 3급 부정교합을 지닌 소아보다 기도너비가 더 작은 것으로 사료된다.

In order to help fresh meat processing industry, a survey on consumer`s purchasing pattern of fresh meat was carried out in the area of apartments and houses in Seoul. A total of 1,000 housewives was interviewed with questionnaires. 1. Among meat and poultry, beef was the first preference, pork was the text and the third was poultry. With the increase of income, the preference for beef increased-as the income increased by 100,000 won, the increased amount of purchase was 300g for beef, 90g for pork and 0.1 head for poultry while with 10,000 won increase of groceries expense, purchase of beef, pork and poultry increased by 1608, 40g 0.04 head respectively. Accordingly, measures to boost the preference for pork and poultry should be taken to reduce the relative preference of high-income group for beef. 2. Because 40% of participants, the highest proportion said they would buy more meat if fresh meat in sold as graded and prepackaged forms with different prices, sales volume would increase if fresh meat industry adops the grading and prepackaging system. The meat color was the main criterion of consumer`s selection of meat at retail shops. Therefore, it is important for fresh meat processing industry to watch freshness of meat, selection of packaging films and temperature control at retail shops carefully to maintain meat color red.
