Stress is resistance to stimuli to destroy a balance of mind and body in order to maintain an original steady state : A type of response and avoidance. Mild stress, which happens in tension, has a positive effect to improve concentration, but most of stress is likely to be a main factor to damage health. This is because it causes physical ailments and psychological diseases (e.g., depression, anger, frustration, loneliness, and anxiety). The purpose of this study is to analyze the difference between two groups, daytime and night university students, on ego-state, stressors, and stress coping types to improve their academic achievement by reducing their stress. There were 266 university students, who participated in a survey from November 30, 2015 until September 30, 2016. The study employed three measuring instruments : Ego-gram, stressor scale, and stress coping type scale. All the collected data were analyzed through regression analysis and t-test. The results of the regression analysis showed no significant differences in ego-state, stressors, and stress coping types between two groups. However, the results of t-test showed significant difference between the two groups : In terms of ego-state, a CP (Critical Parent) average of the night university students was significantly higher than the daytime university students'. Also, there is a significant difference in employment, future issues, and economic issues : the daytime university students considered employment and future issues more serious, while the night university students had more mental burdens of economic issues. When it comes to coping stress types, there was no significant difference between the two groups.
Purpose: Changes in the curvature of the vertebral columns of elderly women with increasing age causes various side effects and disorders. Therefore, this study was conducted to evaluate the effectiveness of the 8-figure scapular brace to improve pulmonary function and balance ability based on lung capacity and foot pressure by increasing the vertebral curvature. Methods: Seventeen elderly women with a forward head posture were selected. Women were asked to wear the 8-figure scapular brace and the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) were measured, as were changes in foot pressure. Measurements were conducted three times each and the mean values were used for subsequent analyses. For static evaluation, we used the paired t-test to identify differences between pre and post values. Results: There was no significant difference in FEV1 and FVC before and after use of the brace (p>0.05); however, there was a significant decrease in forefoot pressure and an increase in rearfoot pressure following application of the brace (p<0.05). Conclusion: Application of the 8-figure scapular brace to correct vertebral curvature in elderly women influenced pressure distribution change from immediate effect body arrange of cervical and thoracic. However, wearing the 8-figure scapular brace may interfere with expansion of the chest and therefore respiratory muscle activity. Accordingly, it is necessary to apply appropriate treatment when wearing a scapular brace and to allow a sufficient intervention period while also providing therapeutic interventions such as posture correction or respiration training.
The purpose of this paper is to study and propose playground facilities for physically challenged children to cultivate adaptability in society and advances the opportunity of participate in physical exercise. This study carried out site investigations by visiting and inspecting various facilities: a recreational walking path for physically challenged people, a care facility for physically challenged children, a special school for physically challenged children, and "Madel Park", a private-use playground for physically challenged children. The result of the site investigation found that, overall, play facilities are difficult to use for physically challenged children. In addition, because park space is often small and narrow, children who are restricted to wheelchairs find it impossible to access such facilities. By carefully inspecting each of the facilities, the author found suitable elements to apply for outside play space. These elements include the introduction of an essential slope way to allow for safe movement, the provision of special seats which support the body to outside play equipment and the adaptation of treatment room instruments that assist balance to outdoor playground facilities. On the basis of the site investigation the interview and the indoor education program for physically challenged children the author completed an outside play program. Each item in this program was classified as belonging to either a "sense play" program or and "exercise play" program. Finally, the author designed suitable play equipment for physically challenged children corresponding to each item in the exercise programs in order to research the appropriateness of the equipment to its intended use. This research is the first step. From this point the author expects that specific applications will be developed through a practical space plan and sufficient clinical experiments involving use of the new equipment.
The objective of this research was to evaluate the growth performance, the apparent ileal digestibility of nitrogen and energy, the retention of nutrients and the apparent metabolizable energy corrected to zero nitrogen retention (AMEn) in broiler chickens supplemented with increasing doses of a worm leachate (WL) as a source of humic substances (HS) in the drinking water. In Exp. 1, 140 male broilers were penned individually and assigned to four WL levels (0%, 10%, 20%, and 30%) mixed in the drinking water from 21 to 49 days of age. Water was offered in plastic bottles tied to the cage. In Exp. 2, 600 male broilers from 21 to 49 days of age housed in floor pens were assigned to three levels of WL (0%, 10%, and 20%) mixed in the drinking water. The WL was mixed with tap water in plastic containers connected by plastic tubing to bell drinkers. The results of both experiments were subjected to analysis of variance and polynomial contrasts. In Exp. 1, the daily water consumption was similar among treatments but the consumption of humic, fulvic, and total humic acids increased linearly (p<0.01) as the WL increased in the drinking water. The feed conversion (p<0.01) and the ileal digestibility of energy, the excretion of dry matter and energy, the retention of dry matter, ash and nitrogen and the AMEn showed quadratic responses (p<0.05) relative to the WL levels in drinking water. In Exp. 2, the increasing level of WL in the drinking water had quadratic effects on the final body weight, daily weight gain and feed conversion ratio (p<0.05). The addition of WL as a source of HS in the drinking water had beneficial effects on the growth performance, ileal digestibility of energy, the retention of nutrients as well on the AMEn in broiler chickens; the best results were observed when the WL was mixed at levels of 20% to 30% in the drinking water.
Objectives: This study was conducted to evaluate the nutrition quotient (NQ) by gender and understand which factors influence NQ in preschool children. Methods: Subjects were 245 children (110 boys, 135 girls) aged 4-6 years and their parents. The questionnaire composed of demographic characteristics, eating behavior factors and the NQ questions. The NQ consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Inbody J05, a measurement device that measures individual's body composition was used to measure children's anthropometric data. All data were statistically analyzed by SPSS program (Ver. 20) and the statistical differences in variables were evaluated by Student t-test, ${\chi}^2-test$, One-way ANOVA and Duncan's multiple range test. Results: The total NQ score of the subjects was 65.3. The NQ score of girls (67.0) was significantly higher than that of the boys (63.2) (p<0.01). The girls' average scores of NQ factors including diversity (p<0.01) and practice (p<0.05) were higher than those of the boys. The analysis of related-factors influencing NQ scores showed that there was a significant difference among the groups according to feeding methods during infancy (p<0.05), breast feeding group being the highest. Furthermore, the NQ score showed a significant difference depending on how to correct children's unbalanced diet as well as parents' nutrition knowledge. The NQ score of obesity group tended to be lower than that of underweight group although there was no significant difference. Conclusions: Overall results indicated that the girls had better quality of diet and eating habits than the boys. Children and their parents need proper nutrition education and counseling to correct children's eating habits and to improve diet quality in kindergartens and in children care centers.
The present study was conducted to evaluate the effects of dietary formulated feed additive on growth performance and carcass traits of Hanwoo steers. A formulated feed additive reported to reduce heat load in the rumen in our previous research was used (Cho et al., 2014). Total 32 herds of Hanwoo steers were assigned into two groups of control and treatment. Total mixed ration was provided as basal diet for cattle and 100 g of additive was supplemented on diet for treatment. Feeding trial was performed during 120 days before slaughter. For growth performance, 3 periods (0~90 days; 90~120 days; 0~120 days) were allotted and average daily gain, feed requirement and final body weight were determined. Loin meat between $12^{th}$ and $13^{th}$ rib was used for meat quality analysis after slaughtering. Only $1^{st}$ period showed significantly improved growth performance of treatment (P<0.05) and there were no significant difference in other periods. At $3^{rd}$ periods (overall), a trend of increased average daily gain was found at treatment (P=0.075). Carcass performance and quality did not show significant differences between treatment and control (P>0.05). In meat quality, treatment showed significant increment in all measured meat colors (P<0.05) and significantly less sharing force compared to the control (P<0.05). Although no significant difference in growth performance and carcass yield were found, remarkably improved economic status was detected in treatment group. In conclusion, it could be suggested that application of a formulated feed additive specialized in reduction of heat load in the rumen was able to increase economical balance through enhancing heat stress condition of ruminant and growth.
To know changes of the food preferences and the practice of pica during pregnancy, ninety two women in the latter half of pregnancy were interviewed in April, 1976 at ten medical centers in Seoul. They were average 27.1 years old, and mostly middle class. 83.7% of the total subjects felt the changes of food preferences due to pregnancy within the first trimester. 60.9% had vomiting as well as losing their appetite and 17.3% vomited three or more times daily which might induce difficulties of water and electrolytes balance in body. The preferences about foods, the taste of foods, and various dishes cooked during morning sickness were changed significantly and showed in lower scores of likes and higher scores of dislikes than those before pregnancy. Particularly, cooked rice and kimchi indicated the increase of more than 50% in dislikes. The preferences after the morning sickness were turned back to those before pregnancy. Desire for water through foods like soft drinks, juice, ice cream, and gamju and salty foods seemed to be spontaneous during pregnancy. A majority of the subjects had three meals and no snack had included more snacks instead of meals during losing appetite and thereafter, had more frequent meals and snacks. Superstitions about chicken, squid, and cuttlefish for pregnant women were prevalent. 11.9% tabooed chicken because of harm for fetus. On the contrary, intended higher inclusions of milk, meat and dried small sardines would be helpful to satisfy the increased recommended allowances of calcium and protein for them. The practice of pica was found in 5.4% and rice was the only real item mentioned. Pica such as amylophagia or geophagia often reported in the U.S. was not answered in this study.
Dietary peptides have recently received attention regarding their beneficial effects on nutrient metabolism since the caseinphosphoptides obtained from casein hydrolysate are generally believed to enhance the intestinal absorption of Ca. The two experiments were conducted to investigate the effects of various hydrolyzed fractions of gluten on Ca bioavailability. The gluten hydrolysate of dietary components was produced by enzymatic hydrolysis of gluten whereas gluten hydrolysate supernationt and its precipiate resulted from centrifugation. In experiment I, the rats were for 4 weeks fed the 4 kinds of diets containing same amount of nitrogen and calories and diffeing only in the forms of nitrogen sources. The diets were gluten (G), gluten hydrolysat(GH), gluten hydrolysate supernatant(GHS) and gluten hydrolysate precipitatie(GHP). Determination was made for the body weight gain, serum Ca concentration, Ca solubility in small intestinal contents, bone weight, length and stength, bone ash and Ca content, and Ca balance, respectively. No significant difference was noticed as regards growth, serum Ca, and bone dimension and Ca content among rat groups. More significant increase was observed with regard to Ca absorption and intestinal solubility in the rats receiving the GH or GHS diet which containe crude gluten peptides, than in those subjected to G or GHP diet. In experiment II, in vitro determination for Ca solubility was made to ascertain the mechanism responsible for the effects of gluten peptides on Ca absorption. The 10mM Ca in potassium phosphate buffer solution(pH 7.0) incubated for 3 hours at 37$^{\circ}C$ by the GHS fraction, was observed to be capable of increasing the Ca solubility at 5-25mg/ml concentration of gluten peptides. These observations suggest that the gluten peptides from gluten hydrolysate may enhance the Ca absorption efficiency by increasing the solubility of Ca in small intestine.
Background: The purpose of this study is to measure the amount of influence of taping and a whole body balance upon muscle strength, endurance, and flexibility. Experiments were conducted by two different groups, specially designed for this study. The choice of exercise methods for each group depends on its own idiosyncratic characteristics (or Each group employs its own idiosyncratic exercise method). Methods: The first group, with taping applied, undertook exercises three times a week; second group just took exercises three times a week. These experiments show the following outcomes. Results: The first group showed a considerable amount of difference in terms of muscle strength, endurance, and flexibility. Second group also showed similar outcome. Both the first group and the second group revealed a considerable difference. But the first group showed a bigger difference than the second group. Conclusion: Thus, the result of these experiments strongly indicates that exercise, with taping applied, turns out the most effective in promoting muscle strength, endurance, and flexibility.
