The purpose of this study was to investigate depression, daily stress and resourcefulness in female high school students and to identify variables influencing resourcefulness. Data were collected 152 female high school students. Data were treated statistics using ANOVA, t-test, Pearson's correlation coefficient, Scheffe's test and Stepwise Regression Analysis. The mean score of depression was 7.29±8.38. There was statistically significant difference in depression on factors such as relationship with parental rearing attitudes, school fellow, satisfaction of school life. The mean score of daily stress was 105.88±19.63. There were statistically significant difference in daily stress on variables such as relationship with school fellow, parental rearing attitudes. The mean score of resourcefulness was 21.68±33.50. There was statistically significant difference in resourcefulness on factors such as academic achievement, satisfaction of school life. Resourcefulness was negatively correlated with depression and daily stress. Depression was positively correlated with daily stress. Factor influencing resourcefulness were daily stress, academic achievement, which explained 35.7%. Further researches with careful sampling will be needed to reinforce the resourcefulness of high school students.

This study was designed to evaluate the effect of pelvic floor muscle exercise using biofeedback and electrical stimulation after normal vaginal delivery. The data were collected from November 1999 to April 2000 at a university hospital located in Seoul, Korea. Out of 49 women with normal vaginal delivery, 25 of experimental group(with exercise) and 24 of control group(without exercise) were questioned about lower urinary symptoms, discomfort during sexual intercourse and daily life. The maximum pressure of pelvic floor muscle contraction(MPPFMC) and duration of pelvic floor muscle contraction(DPFMC) were measured at pre-treatment, the end of treatment and 8 weeks after a treatment program. The pelvic floor muscle exercise program(using biofeedback and electrical stimulation) was applied to the experimental group twice a week for 4 weeks at the incontinence clinic and the pelvic floor muscle exercise at home for that time and more 8 weeks. Data were analyzed by t-test, $x^2$-test, Fisher's exact test and the repeated measures ANOVA. The results were as follows; 1) MPPFMC(p=0.000) and DPFMC(p=0.021) were significantly increased in the experimental group. 2) In the lower urinary symptoms, daily frequency(p=0.001), nocturia(p=0.002), incontinence episode(p=0.016), stress incontinence(p=0.012), quantity of incontinence(p=0.026), straining(p=0.041), and strength of stream(p=0.009) were significantly decreased in the experimental group. 3) Discomfort during sexual intercourse had not a significant difference between the two groups, which was not significantly decreased as time passed. 4) In the discomfort during daily life, activity restriction(p=0.042), exercise restriction (p=0.008), interpersonal relationship restriction(p=0.046), and discomfort of general life(p=0.027) showed a significant difference between the two groups, which were not significantly decreased as time passed. In conclusion, it is suggested that the pelvic floor muscle exercise using biofeedback and electrical stimulation might be a safer and more effective program for the improvement of postpartum pelvic muscle contraction.

The purpose of this study is to investigate the effect of the multimodal cognitive intervention focusing on instrumental daily life on the cognitive function, depression and quality of life of the elderly with high-risk of dementia. This study was conducted on 24 elderly people with high-risk of dementia who participated in cognitive rehabilitation program from March to June, 2018 in Chungbuk A region. The intervention was applied to cognitive training and creative activities related to instrumental daily life. MMSE-DS, Subjective Memory Complaints Questionnaire, Short Geriatric Depression Scale-Korean version and Geriatric quality of life - Dementia were performed before and after the intervention. We confirmed that the subjects showed significant improvement in Subjective Memory Complaints and Quality of Life, but showed no significant changes in cognitive function and depression after the intervention program. Through this study, it was confirmed that this program which can affect the real life of the elderly can be usefully applied in the community. In the future, it will be necessary to develop a program that utilizes more diverse instrumental activities of daily living.

From an analysis of the daily consumption per capita (g/capita/day) in the existing dataset of the Korea National Health and Nutrition Examination Survey 2008, the top seven fruit and vegetable juices (apple, grape, mandarin, orange, pineapple, pomegranate and tomato) commercially available on the Korean market were selected and analyzed. These juices showed a wide range of levels of total phenolics, total flavonoids, and antioxidant capacities. The daily per capita intake of total phenolics from juice consumption was 11.70 mg gallic acid equivalents and that of total flavonoids was 1.65 mg catechin equivalents. The daily per capita intakes antioxidant capacities were 10.42 mg vitamin C equivalents (DPPH assay) and 13.21 mg vitamin C equivalents (ABTS assay). Daily per capita intakes of total phenolics, total flavonoids, and antioxidant capacities were influenced by the compositional content and the daily consumption of fruit and vegetable juices.

Catecholamine levels were determined in the submandibular glands of new born rats treated with physiologieal saline solution or large doses of sodium fluoride (10mg/kg) for verying periods of time. In control group, catecholamine levels were gradually increased from fifth day of life until twenty-fifth day of life. When fluoride treatment was started on the fifth day after birth and continued daily to the thirty-fifthday of life, decreased catecholamine levels were obsrved on the fifth, through all experiments, and thirth-fifth day. Daily fluoride treatment from the fifteenth through the thirty-fifth day after birth induced the decreased catecholamine levels which were higher than the levels in submandibular glands of rats treated from the fifth day to the thirty-fifth day after birth with NaF. These experiments suggest that fluoride may be affecting catecholamine biosynthetic mechanisms which were duveloping during the fifteenth to twenty-fifth day of life.

Objective: We have tested our hypothesis that inclusion of purified glycerol as a replacer of portions of dried distillers grain with solubles (DDGS) would affect growth performance, rumen fermentation and blood parameters, carcass and sensory traits, reducing sugar and glycogen contents, and volatile compound profiles in longissimus thoracis (LT) in Korean cattle steers. Methods: A total of 20 Korean cattle steers (27.0±0.2 months old; 647±10.5 kg body weight [BW]) were assigned to a conventional control group or a glycerol group (3.17% purified glycerol addition as a replacement for DDGS and molasses). The steers were individually allowed to receive the experimental concentrate at the daily amount of 1.5% of their individual BW and a total 1.0 of kg/d of rice straw twice daily. The feeding trial was conducted for a period of 20 weeks. Results: Glycerol supplementation (GS) increased (p = 0.001) concentrate intake. However, GS did not affect (p>0.05) average daily gain, feed efficiency, and ruminal volatile fatty acid concentrations. GS tended to increase (p≤0.10) serum glucose concentrations at the 16th and 20th weeks. GS decreased (p = 0.001) LT pH. GS did not affect (p>0.05) carcass traits and the chemical or physicochemical compositions, reducing sugar or glycogen contents, sensory traits, and most of volatile compounds in the LT. Conclusion: The inclusion of purified glycerol as a replacement for DDGS in the finishing diet did not affect growth performance, rumen fermentation parameters, and carcass quality in Korean cattle. The purified glycerol could be used as a substitute for other energy sources such as DDGS in beef cattle, depending on the price.

This paper has analyzed the problem of the inequality unit in 7th National curriculum 8-Ga stage from the following points. First, in respect to the written questions of the inequality unit over every textbook of 7th National curriculum, how are they allocated according to subject matters and what are their weak points? Second. how many of them are related to the authentic daily life or other subjects and what kind of subjects are they? Third, what are the problems related to the authentic daily life situation or what are the problems that have some inter-sentential errors, and what kinds of measures for their improvement can be taken? In keeping with view points above, we have analyzed the contents in current 16 different textbooks on th basis of their subject matters and especially put the emphasis on the relation to daily life and other subjects. Consequently, we found there are many textbooks that do not include various subject matters and that can not be related to various other subjects. It is necessary to connect mathematics to various daily life matters and other subjects to improve students' creativity and to make students understand the practicality of mathematics.
