In this paper, the flowability, strengths, impact resistance and sulfuric acid resistance of steel fiber reinforced high performance concrete (SFHPC) for the steel fiber content and fly ash and blast furnace slag as admixtures were presented. For evaluating flowability particularly, tests of slump flow, box-type passing ability and L-type filling ability were performed. The slump flow of SFHPC was some decreased with increase of the steel fiber content. At the box-type passing ability, the difference of box height of SFHPC is greatly increased with increasing the fiber content. The L-type filling ability of SFHPC was not excellent above $0.75\% of the steel fiber content. Also, the compressive strength of SFHPC was decreased with increase of the steel fiber content, but the flexural strength of SFHPC was much higher than that of the concrete without the steel fiber. At the impact resistance, drop number of SFHPC for reaching final fracture was increased with increase of the fiber content. Also, the drop number for reaching initial fracture of lmm was increased with increase of the fiber content. At the sulfuric acid resistance, 4-week weight change of SFHPC with the steel fiber was almost similarity that of HPC without the steel fiber and was in the range of 73.6 to 81.5.

Objectives: Stress is the cause of several illnesses, in older people, stress may also cause various social problems. The oral health of older adults is closely related to the quality of life, and chewing ability is particularly important for their general health. The purpose of this study was to investigate the relationship between stress, the number of teeth remaining, and the chewing ability, which reflects the oral health status among older adults. Methods: This study evaluated the stress level and chewing ability of adults older than 65 years using the 6th (2014-2015) Korea National Health and Nutrition Examination data. The total number of remaining teeth was determined based on the data of the teeth conditions. Results: There was an association between stress and chewing ability among older adults. The odds ratio of chewing function increased by 2.67 times (crude OR=2.67; 95% CI=1.88-3.79) with increased stress. After adjusting, the odds ratio increased to 2.74 times (adjusted OR=2.74; 95% CI=1.88-3.98). Conclusions: Reducing stress may facilitate effective oral health management and improve the overall quality of life in older adults. The findings of this study may help in the discovery of various approaches s to reducing stress in older adults and provide relevant information for oral health education.

PURPOSE: Cerebral palsy is a common cause of disability in children, requiring constant rehabilitation. Improving balance in children with cerebral palsy helps to alleviate daily movement and the quality of life. This study examines a program that combines Resistance Exercise and Group Exercise, and investigates the effect on trunk control ability, balance ability, maximum grip strength, and quality of life of children with cerebral palsy. METHODS: Totally, 9 children with cerebral palsy participated in this study. Resistance exercise was performed for 8 weeks, 40 minutes every day. Group Exercise was conducted for 8 weeks, 40 minutes each Sunday. All participants were evaluated by the Korean version of the trunk control measurement scale, pediatric reach test, grip strength test, and KIDSCREEN-52. RESULTS: The trunk control ability was significantly improved in all subcategories (p < .05). In the pediatric reach test, the left and right directions were significantly improved (p < .05). Maximum grip strength was significantly improved in both hands (p < .05). The quality of life significantly improved in total score, physical well-being, general moods, self-perception, autonomy, relationship with parents, and home life (p < .05). CONCLUSION: Considering the encouraging results, we propose to use Resistance Exercise and Group Exercise as programs other than rehabilitation treatment in hospitals, to improve motor function and quality of life of children with cerebral palsy.

This study aimed to investigate the mediating effect of the screen media time of young children on the relationship between mothers' reasons for allowing young children to use screen media and their children's ability to regulate screen media. The participants consisted of 614 children aged 5-6 (312 boys and 302 girls), and all the survey questions were answered by their mothers. Descriptive statistics, Pearson's correlation, structural equation modeling, and bootstrapping analysis were employed to analyze the data using SPSS 25.0 and Mplus 8.6. The results were as follows. First, mothers' educational and ritualized reasons for allowing young children to use screen media and children's screen media time directly affected young children's ability to regulate screen media. Second, children's screen media time mediated the relationship between mothers' educational and ritualized reasons for allowing their children to use screen media and children's ability to regulate screen media. When mothers permitted their children to use screen media for educational purposes, their children were likely to spend less time on screen media usage which, in turn, increased their ability to regulate screen media. Conversely, the more mothers allowed their children to use screen media for ceremonial purposes, the more time their children spent on screen media and the less ability they had to regulate screen media usage. These outcomes suggest that, to improve children's screen media regulation ability, mothers must not routinely allow their children to use screen media and should manage their children's screen media time.

Clinical Observation was made on 29 cases of Hypertensive intracerebral hemorrhage patients in the ICU of In-Chon Oriental Medical Hosptital of Dongguk University from October in 1994 to June in 1996. The observation are ability in daily life(ADL) of patients by Location and Type of Hemorrhage, Amounts of Hematoma, Graeb's Score, Intraventricular Hemorrhage, States 4th Ventricle, Surrounding Edema around the Hematoma, Middle Line Shift, Age, Level of Consciousness. Pupillary Light Reflex and Treatment Modalities. Our conclusions on Prognostic Factors using Computerized Tomographic Findings and Ability in daily Life(ADL) Evaluation in patients with Hypertensive Intracerebral Hemorrhage Patients are as follows. A variety of prognostic factors that influence ADL5+6(%) were observed. 1. ADL5+6($\%$) of total cases was 34.9%. The prognosis were unfavorable when high Graeb score(P<0.05), dilated 4th ventricle(P<0.01), much surrounding edema around the hematoma (P<0.05), unilateral unreactive or both unreactive pupillary light reflex(P<0.05). 2. There was no difference of ADL5+6(%) in both hypertensive basal ganglionic and thalamic intracerebral hemorrhage. 3. The prognosis gets poorer as the volume of hematoma is more than 16cc. But there was no difference of ADL5+6(%) in each group. 4. The prognosis gets poorer in cases with IVH than without IVH. But there was no difference of ADL5+6(%) in each group. 5. The prognosis gets poorer as the middle line shift is more than 6mm. But there was no. difference of ADL5+6(%) in each group. 6. The prognosis gets poorer as the level of consciousness is more than drowsy. But there' was no difference of ADL5+6(%) in each group.
