Blenderized diets are not recommended because of difficulties in providing a constant content of nutrients, phoblems with viscosity and osmolarity, time needed for preparation, and increased risk of contamination. To determine the possibility of substituting commercial formulas for blenderized diets, 27 unconscious patients were randomized into two different groups : blenderized diet group(n=11) and commercial formula group(n=16). Blenderized diets were composed of food sources such as rice, milk, egg, juices and others, and its energy percentage of protein, fat, and carbohydrate was 15%, 30%, and 55%, respetively. Commercial enteral formulas provided 1 kcal/ml and the energy percentage of protein, fat and carbohydrate was 25%, 20% and 55% in greenbia(G) and 20%, 20%, and 60% in Greenbia-DM(GD), repectively. In commercial formula group, five patients with diarrhea, constipation, and high blood glucose level received GD, and the other eleven patients received G. All patients received their lipuid diet for 4 weeks through 16 French rubber nasogastric tube by bolus feeding 6 times daily. The patients in commercial formula group had a similar mean daily calorie intake to the patient in blenderized diet group, 32-34kcal/kg/d and 30-35kcal/kg/d, respectively. Patients given commercial formula gained an averge of 1.7kg in weight but those given blenderized diet lost an average of 2.6kg. There was a trend toward an increase in percent ideal body weight in commercial formula group(94$\pm$5 vs 99$\pm$6%). However, blenderized diet group showed a trend toward a decrease in percent ideal body weight(106$\pm$5 vs $101\pm$6%). The initial levels of total lymphocyte counts, serum albumin and tranferrin were below the normal rante, The mean daily protein intake was significanlty higher for commercial formula group(2.0-2.1g/kg/d) than for blenderized diet group(1.1-1.3g/kg/d). Patient fed cormmercial formula for 4 weeks showed a trend toward an increase in serum albumin(8.1%) and a significant increase in serum transferrin(32.1%) without increasing the levels of blood glucose. GOT, GPT, blood urea nitrogen and serum creatinine. In the blenderized diet group, however, no significant improvement were obseved in the concentration of serum albumin and transferin, compared to initial value. There was a trend toward a decrese in the level of hemoglobin and hematocrit in blenderized deit group but no significnat change in commercial formulas goups. All patients tolerated both diets well and no significant complications were encountered. The results indicate that the commercial enteral formulas tested in this study can be an effective substitution for blenderized diet in unconscious tube-fed patients.

In 1965, Bhatt and Pandey have obtained an analogue of the Whipple's theorem for double series by using Watson's theorem on the sum of a $_3F_2$. The aim of this paper is to derive twenty five results for double series closely related to the analogue of the Whipple's theorem for double series obtained by Bhatt and Pandey. The results are derived with the help of twenty five summation formulas closely related to the Watson's theorem on the sum of a $_3F_2$ obtained recently by Lavoie, Grondin, and Rathie.

The purposes of this paper are to investigate an effect of weight of material and gender on postural stability and to introduce formulas for those. There were five levels of weights 0, 9, 18, 27 and 36 kg, and two levels of genders were conducted. Eight male and five female subjects participated in this experiment, ten tests were performed for each level of weights to measure the postural stability by using the stability platform. The effect of the genders and the load on the postural stability were statistically analysed by the two way ANOVA test and the regression analysis. The ANOVA test showed that the effect of weights was statistically significant on postural stability to the both male and female subjects. And the postural stability of female subjects was better than that of male subjects. A linear regression formula for the balancing time and the load and a formula for the reduction rate postural stability and the relative load were introduced by the regression analysis.

Objectives: To establish the expiration date of herbal decoction pouch, the change in antimicrobial activities was measured according to storage temperature and period. Methods: Five herbal formulas, Gyeji-tang, Jakyakgamcho-tang, Saengmaek-san, Paljung-san, and Dangguisu-san, with antimicrobial activity were selected from 51 herbal formulas commonly used in traditional Korean medical institutions. Five herbal formula decoction pouches were prepared and stored at room temperature (RT) or 4℃ from 0 to 12 weeks to evaluate the antimicrobial activity against Bacillus cereus, Listeria monocytogenes, or Vibrio parahaemolyticus. The antimicrobial activities were evaluated by the disk diffusion method (disk size: 10 mm). Results: The decoction pouches of Gyeji-tang and Jakyakgamcho-tang maintained antimicrobial activity against V. parahaemolyticus from week 0 (14 mm) to week 12 (14 mm) at both temperatures. Saengmaek-san pouch had antimicrobial activities against V. parahaemolyticus and B. cereus from week 0 (19 mm and 20 mm) to week 12 (both 18 mm), respectively. At RT and 4℃, the antimicrobial activity of Paljung-san pouch was maintained week 0 (17 mm) to week 12 (both 13 mm) against B. cereus. Against L. monocytogenes, the antimicrobial activity of Dangguisu-san pouch showed 27 mm at week 0 and 23 mm (RT) and 24 mm (4℃) at week 12, respectively. Conclusion: According to increase of the storage duration, the antimicrobial activities of 5 herbal formula decoction pouches decreased slightly but remained up to 12 weeks. These results can be used as important data to establish the expiration date of herbal formula decoction pouches.

The purpose of this study is to search the effective teaching-learning program by considering how affect on formation of linear function using Excel. This study was based on qualitative case study. The teaching experiment using Excel executed with five 8th graders' students for second research content. Teaching experiment was performed for two classes. Collecting the data was conducted via observations and interviews with students. The data include audio and video recording of the students' work, students' worksheets and detailed field notes. The conclusions drawn from teaching experiment are as follows: First, when students explored relevancy content of function in Excel environment, formation of concept of function was facilitated by experiencing operation of algebraic formulas, tables and graphs. We could infer that formation of concept was effected by conjecture activity and iterative process of feedback through Excel environment. Second, the students explored the changes very interestingly making algebraic formulas and presenting tables and graphs. The students were familiarized with observation on algebraic formulas, graphs and tables concurrently. Also, they tried to look for general rules through inductive observation. According to this study, we noticed that exploration teaming environment using Excel could supplement paper-and-pencil environment.

To evaluate the effect of feeding methods on growth and zinc nutritional status of infants early in life, we monitored from birth to 36 months in 51 infants who were exclusively fed human milk (HM, n=20), casein-based formula (CBF, n=12), or soy-based formula (SBF, n=19) during the first five months of life. Zinc status was assessed by analyzing serum zinc concentrations and zinc intakes. Zinc contents in HM and formulas were measured. Zinc intake was estimated by weighing infants before and after feeding in the HM group and by collecting formula-intake records in the CBF and SBF groups. After solid foods were introduced, all foods consumed were also included to estimate zinc intake. The growth of infants in all groups was similar to that established for normal Korean infants. Human milk zinc concentrations declined as lactation progressed. Zinc concentrations in all formulas tested in this study were higher than HM and were also higher than those claimed by the manufacturers. During the first twelve months, mean serum zinc concentrations of infants were similar in all groups, although infants in the HM group consistently had the lowest zinc intake among the groups, and the overall zinc intake in infants fed SBF was highest. This finding could be explained by the difference zinc bioavailability of HM and formulas. In conclusion, infants fed HM, CBF or SBF has normal growth up to three years of age, although HM contained the lowest zinc concentration followed by CBF, then SBF.
