This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

폴리에스테르 纖維에 대한 스티렌, 아크릴산 단량체 그라프트 重合의 動力學的 考察

단량체농도, 개시제농도, 그라프트반응시간, 반응온도등의 그라프트중합 조건을 변화시켜 가면서 poly (ethylene terephthalate) 필름에 styrene과 acrylid acid(AA)를 각각 그라프트중합시켰다. styrene단량체의 중합에서는 0.5×10^-2M/L~20×10^-2M/L의 농도범위에서는 그라프트중합속도가 styrene의 농도에 비례하지만 그 이상의 농도에서는 그라프트중합속도 R_p는 R_p=styrene^(0.4~0.45)로 표시된다. AA의 경우는 상당한 지연시간이 존재하지만 일단중합이 개시되면 중합속도는 styrene에 비해서 크다. styrene과 AA 전부에서 일정한 개시제농도 범위까지는 그라프트중합속도가 상승되지만 그 이상의 농도에서는 그라프트중합속도가 저하된다. Graft polymerization of acrylic acid (AA) and styrene on poly (ethylene terephthalate) <PET> film using benzoylperoxide <BPO> as initiator wasinvestigated under different conditions including monomer concentration, initiator concentration, graft polymerization temperature and time. With styrene, the rate of graft polymerization increases linearly as the concentration of styrene increase in the range of 5×10^-2M/L~20×10^-2M/L. The rate, however, is proportional to the 0.4~0.5 power of the styrene concentration above 20×10^-2M /L. With AA, there is a retardation period before the polymerization starts. Once the reaction is initiated, however, the rate of polymerization becomes faster than that with styrene. In both cases, the rates increase as the concentrations increase until certain points and the, they decrease thereafter.

The purpose of this study was to investigate not only the variability in the timing and amount of the maximum pubertal spurt in cranial base and mandible, but also its interrelationship with the timing of peak height velocity. This study was carried out by analysing biannual serial lateral cephalometric radiographs of twenty-six males and twenty-one females who were taken from 8.5years to 16.5years old of mean age, according to the established land-marks and linear measurements. The results of this study were summarized as follows. 1. Prevalance fo the maximum growth spurt more than 80 percentage was occurred earlier in all measurements of cranial base and mandible, except posterior cranial base length in the female. 2. In all measurements of cranial base and mandible, the maximum spurt was occurred earlier in the female than the male while it was greater in male in all measurements except ramal height. 3. In body height measurement, the peak height velocity was occurred 2 years earlier for the female(11.0 years old) than the male(13.0 years old). 4. The timing of maximum spurt in anterior cranial base length and total mandibular length in both sexes and ramal height in the female were coincided with PHV. The maximum spurt was occurred in both sexes in all measurements 2 years before or after PHV, except mandibular body length and posterior cranial base length the in female. 5. In all ages, there was significant correlation between th etotal mandibular length and ramal height, and was also correlation between total cranial base length and anterior cranial base length(P<0.05). However, there was no significant correlation between the ramal height and mandibular body length. In addition, there was also no any correlation between the anterior cranial base length and posterior cranial base length in all ages(P>0.05).

3D CT를 이용한 파노라마 방사선 사진상 상악 매복 견치 위치 정보의 유용성 평가

김혜정,박효상,권오원 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.4

3D CT를 이용하여 파노라마에서 얻어진 상악 매복 견치 위치 정보의 유용성을 평가하기 위해, 상악 견치 매복을 주소로 경북대학교병원에 내원한 환자를 대상으로 파노라마 방사선 사진과 3D CT에서의 매복 견치의 위치를 평가하였다. 대상은 25명(남자 7명, 여자 18명)으로 평균 나이는 10.9세(범위 : 8.2 - 15.7세)이며, 35개의 상악 매복 견치 증례를 분석하여 다음의 결과를 얻었다. 첫째, 파노라마 방사선 사진은 확대되어 촬영되므로 3D CT의 계측치보다 상악 견치의 tooth length, crown width, vertical distance 그리고 lateral shift값에서 큰 값을 가졌다. 단, angulation to occlusal plane은 파노라마에서 더 작은 값으로 계측되었다. 둘째, 파노라마 방사선 사진상 상악 견치가 구개측으로 매복된 경우, angulation to occlusal plane은 3D CT보다 작게 측정되고 vertical distance는 더 크게 측정되었다. 셋째, 파노라마 방사선 사진에서 상악 매복 견치의 tooth length, crown width 그리고 순측으로 매복된 경우 상악 견치의 angulation to occlusal plane은 3D CT와 근접된 계측치를 가졌다. 또한 CT와 비교하였을 때, 치근 흡수 정도 평가에 대한 파노라마 방사선 사진의 감수성은 33.3%인 것으로 측정되었다. 파노라마 방사선 사진은 협측 매복견치의 위치는 실제와 유사하다고 생각되나 구개측 매복의 경우 3D CT보다 더 높게, 각도는 더 작게 나타나는 등 상당한 차이가 있어 CT를 이용한 추가적인 검사가 필요하다고 생각된다. Objective: The aim of this study was to evaluate the potency of panoramic radiography for the detection of maxillary impacted canines. Methods: Twenty-five patients were selected, comprised of 7 males (mean age: 10.9 years, range: 8.5 - 14.5 years) and 18 females (mean age: 10.9 years, range: 8.2 - 15.7 years). In total, thirty-five maxillary impacted canines were estimated. The position of the canine and root resorption of adjacent teeth were evaluated on panoramic radiography and 3D CT. Results: Except for angulation to the occlusal plane, the other parameters, such as tooth length, crown width, vertical distance and lateral shift showed larger values on panoramic radiography compared to 3D CT. In palatally impacted cases, the angulation of canine was smaller, and the vertical distance to the occlusal place was larger on panoramic radiography than 3D CT. For labially impacted canines, tooth length, crown width, and angulation to the occlusal plane were similar for the two methods. The sensitivity for detecting root resorption on panoramic radiography was calculated as being 33.3% of 3D CT. Conclusions: The position of labially impacted canines can be effectively estimated using panoramic radiography, but palatally impacted canines need further investigation such as 3D CT for proper diagnosis.

According to the development of the techniques for tooth movement, the research on the orthodontic wires has advanced and the Ni-Ti wire is highlighted these days. The Superelasticity of Ni-Ti wires was studied in tension. The wires were tested by universal testing machine. The elastic modulus was 20×10 exp (3)kg/㎟ in Cr-Ni wires, 21∼25×10(3)kg/㎟ in Co-Cr wires and 5∼6×10 exp (3)kg/㎟ in Ni-Ti wires. The elastic modulus of Ni-Ti wires was opproximately 1/4 of Cr-Ni wires and Co-Cr wires, and the elastic limit of Ni-Ti wires was approximately 4 times of Cr-Ni wires and Co-Cr wires. The permanent strain was approximately 0.5% in stress-strain curve of Ni-Ti wires.
