The factors adopted in this experiment are volume fraction and the diameter and aspect ratio of fiber. The levels of factors are determined by existing studies. The effects of the diameter and mixing volume fraction and the aspect ratio for maximum strength, strain and tangent modulus are analyxed based on the linear multiple regression and we obtained regression equations as follows ; Maximum stress : σ_max=298.59820+95.78361φ-6.36043V_f+0.62067Ar Maximum strain at maximum stress : ε_max=0.021336+0.15746φ+0.05519V_f+0.00181Ar Tangent modulus : E=208209.80+87132.84φ-17286.69V_f-464.9181Ar where φ : diameter V_f : volume fraction Ar : Aspect Ratio

노인의 활동량이 체형 및 영양필요량에 미치는 영향(III) : 활동량에 따른 영양상태를 중심으로 Nutritional status and habitual physical activity

임화재,윤진숙 啓明大學校 生活科學硏究所 1990 科學論集 Vol.16 No.-

This study was intended to investigate the relationship between habitual physical activity and nutritional status of elderly women over 60 years in Tae-gu area. Past and current physical activity of subjects were classified by activity questionnaire and daily energy expenditure. Dietary intake was measured by convenient method and N balance was calculated from urinary urea nitrogen content and protein intake. The results were as follows : 1. Environmental factors such as participation in elderly club, pocket money, resident type were significantly related to the intensity of physical activity. 2. Anthropometric indicators such as height, weight, skinfold thickness, and arm circumference were significantly lower in the group with more past physical activity. 3. Dietary intake of all the nutrients except fat was significantly higher in groups with more current physical activity. Our data suggested that recommended energy intake of elderly women would be 1400-1750 Kcal according to their activity level and protein intake would be followed by Korean recommended dietary allowance. It is also suggested that maintaining habitual physical activity moderately is beneficial for optimal nutrition intake.

잔골재 입도 및 배합조건이 모르타르의 작업성능에 미치는 영향

정재동,최영화 대구대학교 과학기술연구소 1996 科學技術硏究 Vol.3 No.1

Recently, the mortar crack on floor is very serious in construction field, e.g. the crack due to plastic shrinkage and the crack due to drying shrinkage. To prevent this kind of crack, optimum mix proportions not only satisfying the required workability but also minimizing the unit water content were selected. And the expansion admixtures were used to compensate the shrinkage of mortar. This study shows that water/cement ratio used in construction field is about 64%. Even if we reduce water/cement ratio of mortar by the appropriate use the fine aggregate with high fineness modulus and supezplastizer, floor mortar can have the required workability. The equations between mortar flow and water/cement ratio, sand/cement ratio, fineness modulus of fine aggregate were proposed in this study. And this equation may provide available mix proportions of floor mortar.

Effect of Coating mulberry leaves with ginseng solution on the weight of larva and cocoon, the cocoon layer ratio, the activities of GOT and GPT that are known to be important in amino acid metabolism. the activity of amylase. and the contents of cholesterol, triglyceride and sugar was investigated. The results are summerized as follows 1. Ginseng solution coated mulberry leaves were more effective in increasing the weight of larva and cocoon layer, and the cocoon Layer Ratio than non-coated leaves. 2. The activities of GOT and GPT in silkworms feeded with ginseng solution coated mulberry leaves decreased, and were inversely related with the concentration of ginseng. 3. The activity of amylase in silkworms feeded with ginseng solution coated mulberry leaves decreased, and was inversely related with the concentration of ginseng. 4. The contents of total cholesterol and triglyceride in silkworms feeded with ginseng solution coated mulberry leaves decreased. 5. The content of sugar in silkworms feeded with ginseng solution coated mulberry leaves decreased and appeared not to be inf1uenced by the concentration of ginseng.

각종 악성종양질환에서의 세포면역 기능에 대한 연구 : 말초 혈액 T 임파구 아형 분포 및 지연형 과민반응에 대한 검색 Delayed Cutaneous Hypersensitivity and Peripheral Blood T-lymphocyte Subsets

The author studied delayed cutaneous hypersensitivity and peripheral blood T-lymphocyte subpopulations in 54 patients with malignant tumors. 1. The number and total score of positive reactions in delayed cutaneous hypersensitivity were significantly decreased in cancer patients(p<0.005, p<0.05). 2. Percent OKT4^+ T-lymphocyte in cancer patients were significantly decreased compared to normal control subjects (p <0. 05), and it had positive correlation with total score of delayed cutaneous hypersensitivity reactions(r=0.768). 3. Percent OKT8^+ cells were not different from that of normal control subjects. 4. The ratio of OKT4^+/OKT8^+ in cancer patients were not different from that of normal control subjects except in patients with colorectal carcinoma and malignant lymphomas. 5. Markers of activated T-lymphocyte, OKT10^+ and OKIal^+ cells were increased in all the patient groups. 6. Leu7^+ cells, reflecting natural killer cells, were not different from normal control subjects These results suggest that the cancer patients have depressed cellular immune functions, which mainly results from the decrease of helper T lymphocyte number. Short of functional assays of cellular immunity, the author concluded that the testing of delayed cutaneous hypersensitivity and enumeration of peripheral blood lymphocyte subsets, especially OKT4^+ cells and activated T cells provide useful informations on cellular immune reactivity in cancer patients. Further studies on prognostic value of these parameters should be pursued.

Despite intensive investigation into paraquat toxicity, neither the final cytotoxic mechanism nor a clinically useful antidote has been discovered. The mechanism of paraquat cytotoxicity is also debatable, but it is generally accepted that a redox reaction occurs between reduced paraquat and molecular oxygen. The intracellular reduction of paraquat occurs by various enzymes, such as DT-diaphorase, xanthine oxidase and glutathione reductase. In present study, we investigated that the effects of allopurinol, a xanthine oxidase inhibitor, and dicumarol, a DT-diaphorase inhibitor, in paraquat-intoxicated rats. The survivals of paraquat-intoxicated rats were increased by allopurinol treatment compared to paraquat-treated control rats , but not effected by dicumarol treatment. The activity of xanthine oxidase in the liver of allopurinol-treated rats was decreased and DT-diaphorase activity in liver of dicumarol treated rats was also decreased compared to normal control rats. The contents of glutathione in liver of paraquat treated rats was decreased but in paraquat+allopurinol treated rats, the decrements of glutathione contents was reduced but in paraquat+dicumarol treated rats, liver glutathione level was not changed compared to paraquat-treated rats. These results suggest that paraquat toxicity maybe reduced by administration of allopurinol but dicumarol did not have such effects .

We investigated in the contents of TIBC, SI and UIBC in the mouse blood after treatment with paraquat and/or ginseng extracts. Blood TIBC were mild decreased less than 10% both of 24 hours and 96hours paraquat group than control group. And administration of lipophilic extracts were highest elevated effect on TIBC level. Lipophilic extracts were best increased(p<0.01) on SI level. But alcohol soluble extract were rapidly normalization stabled by crisis of paraquat on SI level. And total saponine were not appeared specific effect on blood TIBC, SI, and UIBC than other ginseng extract in rats. Water soluble extract were highest increase(p<0.01) on UIBC. And blood UIBC were increased p<0.05 in 24 hours paraquat group but after 96 hours late were decreased p<0.01. That the result of SI were very intensely reacted decrease until 50% SI(p<0.01) in initial 24 hours paraquat but 96 hours later were too much increased about 306%(p<0.01) on serum level than 24hours initial paraquat.
