To clarify the apparent hypoplasia of the descending aorta in infants with atrioventricular septal defect[AVSD] patients, we reviewed the catheterization data and angiograms of 34 consecutive patients with AVSD less than 1 year of age who underwent repair at our institution since 1985. We compared them to 10 patients with Atrial Septal Defect[ASD] and 10 patients with Ventricular Septal Defect[VSD] who were matched for age, size and Qp/Qs. The Descending Aorta Index [DAI] of the AVSD group was not different from the VSD or ASD groups, [147.9$\pm$ 34.8 mm2/m2 versus 158.6$\pm$ 31.5 mm2/m2 and 153.2$\pm$ 43.1 mm2/m2].However, the Pulmonary Artery Index [PAI] of the AVSD group was significantly larger than the other groups [684.3$\pm$ 170.7 mm2/m2 versus 454.1$\pm$ 109.1 mm2/m2 and 534.9$\pm$ 148.4 mm2/m2][p<0.05], as was the ratio of PAI/DAI in the AVSD group [4.99$\pm$ 1.77 versus 2.89$\pm$ 0.81 and 3.6$\pm$ 0.92][p<0.05]. Despite similar Qp/Qs ratios, both the mean PA pressure and the Rp/Rs in the AVSD group was higher than the VSD and ASD groups: 43.1$\pm$ 15.6 mmHg versus 29$\pm$ 11.6 mmHg and 24$\pm$ 18.1 mmHg [p<0.05], and 0.27$\pm$ 0.22 versus 0.14$\pm$ 0.03 and 0.11$\pm$ 0.05 [p<0.05] respectively. The apparent hypoplasia of the descending aorta in infants with AVSD is an illusion created by the abnormally large pulmonary arteries, which are significantly larger than in patients with ASDs or VSDs.

Acute pulmonary edema was induced by intravenous injection of epinephrine, intravenous infusion of dextran and intratracheal instillation of acid solution index was determined from pressure volume curves in excised lungs. Surface activity was also investigated with measurements of maximum and minimum surface tension and stability index on saline extracts of same lungs. The results were as follows. 1. The expansion index of excised lung in which pulmonary edema was induced by intravenous injection of epinephrine, intravenous infusion of dextran and intratracheal instillation of acid solution was ignificantly decreased as compared with the normal control of $0.86{\pm}0.017$ to $0.74{\pm}0.03$, $0.71{\pm}0.081$and $0.76{\pm}0.02$, respectively. 2. The deflation curves of excised lungs in which pulmonary edema was induced were significantly decreased as compared with the normal controls. 3. The minimum surface tension of excised lung in which pulmonary edema was induced was significantly increased in each groups and stability index was significantly decreased as compared with the normal controls 0.78 to $0.35{\pm}0.039$, $0.29{\pm}0.02 $ and $0.31{\pm}0.083$, respectively. 4. The decrease of pulmonary surface activity in acute pulmonary edema was in proportion to the degree of pulmonary edema regardless of their etiology.

This study was designed to determine blood glucose responses to some cereals produced in Korea. The levels of blood glucose were measured over 2 hours after feeding healthy vounteers with 50g carbohydrate portions. The glycemic index(GI)k and glycemic index-rice(GI-rice) of a food has been defined as : GI=mean of (blood glucose response area of test food/ blood glucose response area of glucose taken by the same indicidual) $\times$100 and GI-rice=mean of (blood glucose response area of test food/blood glucose response area of rice taken by the same individual) $\times$100. The area under the curve is taken to be the area above the fasting value calculated geometrically from blood glucose increments. The GI of barely to glucose as the standard(57$\pm$7) was significantly (p<0.05) lower than those of other cereals whereas the GI of glutinous rice (110$\pm$8) was significantly (p<0.05) higher than other those of cereals. The GI values to rice as the standard were 63 $\pm$6 for barley, 79$\pm$5 for buckwheat, 85$\pm$6 for foxtail millet, 90$\pm$12 for unpolished rice, 100$\pm$0 for rice, 102$\pm$7 for glutinous rice, 106 $\pm$6 for unpolished glutinous rice, 115$\pm$13 for glutinous millet, 116$\pm$13 fro job's tear, and 122 $\pm$ 4 glutinous sorghum. The mean GI-rice was identical to the mean of the adjusted GI values, with a correlation coefficient of r=0.964(p<0.0001). This finding suggests that white rice could be used as standard food for the determination of GI.

This study was aimed for evaluating the validity of relative-productivity index on the basis of working hour(RPHW index) designed by author as new productivity index and drawing up a plan of bettering productivity to cope with financial difficulty of dental laboratories. Fortyeight dental laboratories extracted by cluster-sampling method form all the dental laboratories in Seoul were subjected for this study. And in each of them, the term of establishment which was divied into three group as short-term, mid-term and long-term group, the scale of dental laboratory which as divided into two group by number of dental technician as small-scale group and large-scale group, the salary system which was composed of salary criteria, pay according to ablility criteria and collectiveagree, the salary level, simple labor productivity index(SLP index), relative-productivity index on the basis of worker number(ROWN) and relative-productivity index on the basis of working hour(RPWH index) were surveyed through the self-administractive questionaires. The results as follows : Most of dental laboratories(93.6%) were managed by non-professional managers. The establishment rate per year of dental laboratory was the increase. The mean number of employees of dental laboratories was $7.00{\pm}3.90$ person. The ratio of smallscale group(under the 5 employees) was 42.6% and as the term of establishment was shorter, the ratio of small-scale group was higher. The mean establishment area of dental laboratories was $24.49{\pm}10.97$ unit and the mean establishment area per head of dental laboratories was $4.05{\pm}3.90$ unit. The estabilshment area and area per head were not significantly associted with the term of establishment, but as the term of establishment was shorter, the estabkishment area per head was slightly wider. The establishment area per head in small-scale group was significantly wider than large-scale group(over the 6 emplayees) The salary criteria(54.4%), pay according to ability(79.2)m ability criteria(77.1%) and collectiveagree(79.2%) as salary systems were used in the most of all dnetal laboratoies. The all salary systems were not significantly associated with the term of establishment and the scale of dental laboratories. The monthly mean salary level of dental laboratoies was $125.64{\pm}31.06$ milion won. The monthly salary level was not significantly associated with the term of establishment and the scale of dental laboratores. But the monthly salary level in the short-term group and the small-scale group were slightly lower than others. The SLP index, the RPWN index and the RPWH index of dental laboratories were $132.16{\pm}48.41$, $382.41{\pm}128.76$ and $76.06{\pm}25.11$, respectively. The SLP, the RPWN and the RPWH of dental laboratories were not significantly associated with the term SLP, the RPWN and the RPWH of dental laboratories were significantly associated with the area of dental laboratory and the salary level. Except for only the association salary criteria among salary system with RPWH of dental laboratories, all other salary system were not associated with the SLP, the RPWN and the RPWH of dental laboratories.

The purpose of this study was to investigate nutrients intake, Rohrer index, serum cholesterol level, blood pressure and others for clinical and nutritional study on school children in Taejon. This survey was carried out in October, 1995. The subjects were 362 children, 6 to 11 years old. The results were summarized as follows. By Rohrer index, 4.6% of the children was lean, 69.6% was normal, 17.4% was overweight and 8.6% was obese group. Systolic blood pressure, diastolic blood pressure and skin fold thickness of all subjects were 111.7$\pm$15.7mmHg, 69.8$\pm$14.9mmHg and 14.5$\pm$7.3mm respectively. Systolic blood pressure and skin fold thickness were increased with Rohrer index. Total cholesterol, urea nitrogen and creatinine levels in blood were 160.8$\pm$23.9mm/dl, 11.5$\pm$3.5mm/dl and 0.71$\pm$0.12mm/dl respectively but not significantly different among groups. These levels have a slight tendency to increase in obese group but not significantly different among groups. Hematocrit and hemoglobin levels were 41.3$\pm$4.7%, 13.1$\pm$1.6g/dl. These levels of 11 years old girls were lower than same aged boys. Composition ratio of total energy intakes were 65% of CHO, 13% of protein and 22% of fat. Energy and most nutrients intakes were insufficient except for P and vitamin C. Especially the amount of vitamin A, Fe, Zn and folate intakes were lower than halves of RDA'S. Most nutrients intake were not significantly different among groups. Pearson' correlation in Rohrer index with nutrients intakes were all negative correlation significantly different of K, Na and Thiamin.

Thirteen sternocosal elevations for pectus excavatum were performed on twelve patients between Jan 1989 and Sep. 1991. Eleven among the twleve patients were male. The subjects ranged in age from 2 years to 20 years, with a mean age of 8.33 years[SD=4.80 years], Eleven patients were below 15 years. The early postoperative evaluation by Humphreys` criteria except keloid formation was excellent in all the patients. The lower vertebral index[LVI], configuration index[CI], and upper vertebral index[UVI] were measured on the lateral chest roentgenogram. The LVI and CI improved significantly from 0.31$\pm$0.06 and 1.14$\pm$0.06 preoperatively to 0.25$\pm$0.03 and 0.78$\pm$1.10 postoperatively. The degrees of depression, flatness, and asymmetry and funnel index were measured at the most deformed portion on the computed tomgram performed pre- and postoperatively. The degrees of depression and funnel index improved significantly from 3.32$\pm$0.73 and 5.77$\pm$1. 54 preoperatively to 1.85$\pm$0.14 and 2.96$\pm$0.43 postoperatively, There was no significant change in the degree of flatness however, Six postoperative morbidities occurred in five patients Three were superficial wound infection, two hemopneumothorax, and one reoeration, Reoperation was performed due to forward displacement of the distal sternum below the posterior sternotomy, The findings of this study suggest that the sternocostal elevation is an excellent primary method for the pectus excavatum of children and young adolescents.
