For the purpose of estimating the status of physical growth of primary school students in Busan area, the author had performed and investigation and analysis on the physical integrated value for past 6 years of random sampled 656 students (male 374, female 282). The summarized results were as follows : 1. The most rapid growth age of body-height was 7-8 years old ad 5.9cm in male and 10-11 years old in female as 6.5cm, and the growth curve of body-height was crossed at 10-11 years old. 2. The most rapid growth age of body-weight was 9-10 years old as 3.1kg in male and 10-11 years old in female as 3.9kg, and the growth curve of body-weight was crossed at 10-11 years old. 3. The most rapid growth age of chest-girth was 8-9 years old as 3.1cm in male and 9-10 years old in female as 2.9cm, and the growth curve of chest-girth was not crossed. 4. The most rapid growth age of sitting-height was 6-7 years old in both sex as 3.3cm and 3.4cm, and the growth curve of sitting-height was crossed at 8-9 years old. 5. Using the physical integrated value was much simple and desirable at comparing with the areas. And the physical integrated value of primary school students on Busan area compared to Korean standard physical status was relatively good as body-height +0.33, +0.30, body-weight +0.33, +0.35, chest-girth +0.65, +0.57 and sitting-height +0.10, +0.20 with each sex.

The use of alginate impression materials today is prevalent because of its efficiency and simplicity in clinical settings. Unfortunately, the simplicity of the procedure tends to lull the dentist into a sense of well-being, and lead him into using careless or sloppy technique. Alginate impression materials are used to fabricate diagnostic and preliminary casts, and the final cast. Incorrect use of this material is known to affect the accuracy of the final prosthesis. The purpose of this study was to compare the effect of different mixing methods of alginate impression material and tray adhesive on the accuracy of the stone cast produced by each method. A total of 30 stone casts were produced by using 3 different types of mixing methods (10 stone cast for each mixing method, respectively) The first method utilized an automatic-mixing machine to mix alginate while the second method was carried out manually, strictly following manufacturer's instructions. The third method also involved manual mixing, but did not follow the manufacturer's instructions and was done in a random fashion. Also, 20 additional stone casts were produced by using alginate with or without tray adhesives were included in the study to evaluate effects of tray adhesives on the accuracy of alginate impression. 10 stone casts were produced by adding tray adhesives to the interior surface of the impression tray prior to taking the impression. The other 10 excluded this step. A total of 50 stone casts were analyzed by the three-dimensional measuring machine to measure and compare the dimensional changes of the impression material of each group. The results are as follows. 1. No significant difference was found between the automatic mixing group and the manually-mixing group(p>0.05). 2. For the group that followed manufacturer's instructions, less dimensional changes were recorded than the group that didn't in measuring distance d4(p<0.05) 3. The group that used tray adhesives showed less dimensional changes(p<0.05). The findings revealed that mechanical methods of mixing alginate impression materials had little influence on dimensional changes. However, it is proven that following manufacturers instructions in alginate impression taking is an important step in acquiring accurate impressions and tray adhesives may play an important role in enhancing the results.

The aim of this study was to compare wear resistance of resin denture teeth opposing various restorative materials. The wear resistance of conventional acrylic resin teeth (Trubyte Biotone) and three high-strength resin teeth(Bioform IPN, Endura, SR-Orthosit-PE) opposing different restorative materials (gold alloys, dental porcelain, composite resin) was compared. Wear tests were conducted with a sliding-induced wear testing apparatus which applied 100,000 strokes to the specimen in an mesio-distal direction under conditions of 100 stroke/min and constant loading of 1Kgf/tooth. Wear resistance of the resin denture teeth was evaluated by the following criteria : 1) wear depth, 2)weight loss, and 3) SEM observation. Results were as follows. 1. When opposed to gold alloys and composite resin, high-strength resin teeth showed superior wear resistance compared to acrylic resin teeth. But, in cases opposing dental porcelain, differences between the wear of the high-strength and acrylic resin teeth were not statistically significant (p<0.05). 2. When comparing wear resistance among high-strength resin teeth, opposing gold alloys, Endura was slightly more resistant and while in cases opposing dental porcelain, SR-Orthosit-PE was showed to be slightly resistant(p<0.05). 3. The wear of high-strength resin teeth was greater by 5 to 7 times when opposing porcelain and 2 to 3 times when opposing composite resin compared to gold alloys(p<0.05). 4. SEM observations of the wear surface showed that wear of resin teeth opposing gold alloys is a fatigue type of wear and wear of resin teeth opposing dental porcelain is fatigue and abrasion type of wear. Trubyte Biotone showed more severe fatigue type of wear than high-strength resin teeth. In conclusion, the use of dental porcelain should seriously be considered as restorative material in cases opposing resin denture teeth and improvement seems to be needed on resin teeth in the areas of wear resistance.

We studied the serum electrolytes in the 727 normal persons who visited Busan University hosptial, Benedict Hospital and Maryknoll Hospital from 1970 to 1976. The results were as follows: 1. Mean value of the serum Na+ being measured in 729 normal persons was 138.7+/-6.2mEq/L and 140+/-6.5mEq/L in 450 male, while 136.8+/-6.6mEq/L in 279 female. 2. Mean value of serum Cl- being measured in 701 persons was 99.6+/-5.9mEq/L, and 99.7+/-6.0mEq/L in 437 male while 100+/-5.7mEq/L in 264 female. 3. Mean value of serum K+ being measured in 707 normal persons was 4.4+/-0.9mEq/L in 434 male, while 4.2+/-0.8mEq/L in 273 female. 4. Mean value of serum Ca+ being measured in 557 normal persons was 4.5+/-0.6mEq/L and 4.7+/-0.7mEq/l in 355 male, while 4.3+/-0.5mEq/L in 202 female. 5. Mean value of serum phosphorus being measured in 94 normol persons was 4.2+/-0.6mg%, and 4.1+/-1.0mg% in 65 male, while 4.5+/-1.5mg% in 29 female.
