        姜英豪,金仁達 서울大學校 保健大學院 1968 公衆保健雜誌 Vol.5 No.2

        A study was conducted by the author in September 1968 towards the infants and young children in some underprivileged rural villages of Korea by employing such methods as clinical assessment, nutritional biometry, and biochemical tests, in an attempt to evaluate their nutritional status with possible reference to protein calorie malnutrition (PCM). The infants and young children examined totaled 232 of whom 111 were boys and 121 were girls. The results are as follows: Ⅰ. Clinical Assessment The prevalence rates of the signs suggestive of PCM turned out to be as below : 1) Cases with dyspigmented hair were observed with 4.5% of the 45 infants examined. and 18.8% of the 187 young children examined. Cases with thin and sparse hair were seen with 22.8% of the infants, 14.0% of the young children, and l5.2% of both the infants and young children. 2) Prevalence of the pale conjunctiva rated 28.6% of the infants. 32.3% of the young children, and 30.4% of both the infants and young children. 3) Keratomalacia cases were found in 0.5% of the young children only and they corresponded, in turn, to 0.4% of the whole examined. 4) Cases with angulostomatitis rated 14.0% of the young children only, who constituted 10.0% of the total examined. 5) Those with moon-face were observed only with 2.3% of the infants, rating 0.4% of the total. 6) Cases with flaky-paint dermatosis were observed with 2.3% of the infants, 0.5% of the young children, and 0.9% of both the infants and young children. 7) Those who were found to have such skin lesions as fissure of the ear lobe, tender sores, or moist groin rash rated 15.9% of the infants, 20.4% of the young children, and 19.6% of both the infants and children. 8) Rate of those with muscles wasted was 11.4% of the infants, 25.8% of the young children, and 23.0% of both the infants and young children. 9) Those with edema were observed only with 0.5% of the young children. rating 0.4% of the total. 10) Psychomotor changes (apathetic, miserable, inert, withdrawn, or anorexic) rated 7.0% of the young children only, and 5.7% of the whole examined. 11) Prevalence rate of diarrhea precipitating dehydration and such other conditioning infections as thrush was found to be 20.5% of the infants, 7.5% of the young children, and 10.0% of both the infants and young children. 12) The results of clinical assessment led the author to the following findings: (1) Those corresponding to 29.1% of the whole examined had one or two combined signs suggestive of PCM. (2) Those with three or more signs combined rated 1.3% of the total children examined. (3) No clinically obvious kwashiorkor was found, but each of the component signs which, in constant combination, characterize it (edema, muscle-wasting, and psychomotor changes) was separately observed mainly with the young children as presented in table 2. (4) Those who impressed the author with clinically obvious nutritional marasmus were 6.7% of the infants, 3.2% of the young children, and 3.9% of both the infants and young children. Ⅱ. Nutritional Biometry 1) The mean heights. weights, chest circumference, and head circumference obtained were as shown in table 3. 2) The mean triceps skin-fold thickness, upper mid-arm-circumference. and upper-mid-arm-muscle circumference were as presented in table 4. 3) Distribution of the heights by four levels of 10% intervals indicated underweights in the light of Korean general standard, as shown in table 10. 4) Distribution of the weights contrasted likewise with the Korean general standard were as shown in table 11. 5) The underweights demonstrated by cases of mild-moderate PCM computed at four levels of 10% intervals as against the Korean general standard, rated 42.2% of the infants, 42.8% of the young children, and 42.7% of both the infants and young children. by the criteria Dr. Jelliffe suggested ??. The severe PCM cases were comprised 31.1% of the infants, 7.5% of the young children. and 12.1% of both groups of them. In the light of the above rates, more than a half of the children examined were found to be affected with PCM ascribable to deficiency of both the protein and calorie. 6) The cases with "Chest circumference/Head circumference Ratio being below 1 after the first 6 months of life" suggestive of the wasting of pectoral muscles which is attributable to PCM corresponded to 57.1% of the infants, 25.1% of the young children, and 29.3% of both the infants and young children as shown in table 13. Ⅲ. Biochemical Tests 1) Hemoglobin levels were found to be anemic (level less than 10.8gm%) with 13.8% of the 80 children examined as presented in table 5. 2) Serum total protein and serum albumin levels were as shown in tables 6 and 7, respectively. The serum albumin levels turned out to be normal with 75.9%, and "low"(2.80gm%∼3.51gm%) with 24.1% of the examined. No deficiency level (less than 2.80gm%) was found among the 29 children. 3) Serum iron content and total serum iron-bindin capacity (TIBC) were as shown in table 8. The deficiency levels of serum iron content less than 50 microgram % comprised 33.3% of the 21 children examined. Those corresponding to 25% and 75% of the 16 children examined had values of TIBC within normal range (300 microgram %∼400 microgram %) and values below the normal range (less than 300 microgram %), respectively, and no case exceeded over the range of normality inspite of the low serum iron content, suggesting the possible ascription to chronic protein deficiency ??. 4) "Urinary Urea-nitrogen / Creatinie-nitrogen excretion Ratios" regarded as an approximte index of dietary adequacy related to muscle storage of protein were obtained as presented in table 9. The cases with the ratios "30 or less" (an indication of malnutrition related to dietary adequacy of protein) rated 58.8% of the 34 children examined.

        김정수,김종인,김영모 公州大學校스포츠科學硏究所 2001 스포츠科學硏究所論文集 Vol.- No.15

        I. Conclusions The purpose of this study is to analyze the kinematics variable of triple jump action. The subjects in this study were total 3 athletes of a class of national team. For this study, three-dimensional visual analysis by use of DLT method was used after making a film of a movement during a contest. As a result of calculating the mean and standard deviation by analyzing distance, time, speed, angle factor, etc. of the kinematics variables, the results has been obtained as follows: 1. It was shown that a phase distance and a phase ratio for all athletes were 37.2±0.15% and they showed a hop-dominated technique commonly, and the subject A jumped to the longest distance of 6.01m and also had the best ability to jump in step and jump distance. 2. In aspects of height of the body center, it was shown that the subject B had the highest body center at each phase take-off moment. And in height changes of the body center from a hop landing to a step take-off moment, the subject B had the highest height of 9cm, and the subject B and C had the highest heights of 22cm from step landing to jump take-off. 3. In aspects of distance from the body center to a landing lag, it was shown that the subject B had the shortest distance of 54.8cm in hop take-off moment and the longest distance of 57.5cm in hop landing moment. 4. In aspects of flying time of each phase, it was shown that the subject A had the longest time of 0.55s at hop, 0.46s at step and 0.71s at jump respectively. 5. In aspects of a horizontal speed at each phase, it was shown that the subject A had the fast time of 9.55m/s at hop, 7.94m/s at step and 6.66m/s at jump respectively. And in aspects of a vertical speed at each phase, the subject A had the slowest speed of 2.03m/s at hop, but had the fast speed of 3.25m/s at jump. In vertical speed at a moment of each phase take-off, it was shown that both subjects B and C had the speed changes in the form of middle-low-high but the subject A had the speed changes in the form of gradually increasing. 6. In aspects of take-off angle of the body center at a moment of each phase take-off, it was shown that all of the subjects had the gradually increasing take-off angle. But, the subject A had the lowest take-off angle of 12.0 at hop. This was a value similar to the international value, that is, when comparing to an overseas proceeded study, the mean value of take-off angle of a hop was shown as 12.5. 7. In aspects of changes of a coxa angle, it was shown that a coxa angle of a free leg was small as the subject C had 101 at hop, subject B 100.2 at step and subject A 100.5 at jump respectively, but for a coxa angle at a moment of hop, step and jump take-off, all of subjects had an angle more than 100. 8. In aspects of an angle of ankle joint, it was shown that the subject C had the largest ankle angle of 126.9 at take-off moment and the subject A had the largest angle of 108.8 and 115.5 at step and jump moment respectively, and the subject A had the smaller angle of 84.9 than other subjects at hop and step landing moments. II. Propositions As a result of this study, we recommend that the following proposition shall be observed for ensuring the succeeding action improvement policy and follow-up study. It is necessary that all of three subjects shall change the hop-dominated technique to the jump-dominated technique. And, maintaining the upper body to be a perpendicular posture if possible at the moment of each phase landing can result in easy and smooth transferring to the next action without any interruptions. A modeling study on the kinematics variables at the last three-step before take-off board of triple jump and phase ratio for the new phase is to be considered.

        Study objective: To compare patients with acute poisoning between urban and rural areas Design: Retrospective chart review of 217 patients with acute poisoning Setting: Two University Hospital EDs Methods: patients were divided into two groups according to hospital. The group A was 109 patients who came to ED of Asan Medical Center and the group B was patients who came to ED of Ajou University Hospital from June 1994 to February 1995. We analysed the age and sex distributions, poisoning substances. causes of poisoning and the past history of psychiatric problems in patients of the two groups. Results: Total number of patients with acute poisoning were 109 in the group A and 108 in the group B. Female was more prevalent than male in the group A and male was more than female in the group B. There was a significant difference in sex distribution between two groups. The mean age of the group A was 27.7 years which was significantly different from the mean age of the group B, 33.7 years. The age incidences in both group were highest in 2nd decade. The accidental poisoning cases were 37% in the group A and 31% in the group B. The rates of committed suicide were 7% in the group A and 22% in the group B. The most common agent of poisoning was therapeutic drug in the group A and agricultural or industrial chemical in the group B. The overall mortality was 5% in the group A and 15% in the group B. Conclusion: There were significant differences in age and sex distributions. poisoning substances, causes of poisoning and the past history of psychiatric problems between two groups.

      • 파골세포 활성에 있어 gp130과 PTH의 연관성

        김영준,류현모,김신윤,신홍인 경북대학교 병원 2002 경북대학교병원의학연구소논문집 Vol.6 No.1

        gp130,a subunit for serveral cytokine signal transducing receptors, mediates diverse activities including osteoclastogenesis. In vitro obaervations suggest that PTH also triggers the gp130-mediated signal for bone resorption by stimulating secretion of IL-6,IL-11 and LIF from osteoblast/stromal cells. Though this gp130 signaling is required for full activation of bone resporption by PTH in vitro, the relationship between PTH and gp130 signaling pathway in vitro is not yet clanified. To address the importance of gp130 as a mediator of PTH action in osteoclast activation, the blood ionized calium and blood serum PTH level was investigated in gp130-/- and wild type mice at E18.5 using a CIBA/Coming 634 Ca^+2/pH analyzer and rat intact PTH Kit, respectively.In addition, calium transport efficiency was assessed from gp130 mice at E17.5. The resorptive activity of osteoclasts from intact calvariae by a ^45Ca release assay and the osteoclastic developmental condition in tibiae were also analyzed, respectively.The gp130-/- micerevealed significantly lower ionized calcium level(1.44±0.03 vs1.77±0.03 mmol/ℓ, p<0.001)and significantly higher blood serum PTH(251.8±5.3 VS 20.5±5.3 pg/㎖,p<0.001) compared to wild type littermates.There was no remarkable pathologic change of placenta in gp130-/- and the ^45Ca transport though placenta was accelerated in gp130-/- compared to wild type littermates(%to Het 83%in -/- vs 148% in +/+).The gp130-/- embryos had small skeletons with bones containing little primary spongiosa, and large multinucleated TRAP+ cells along the lower border of the growth plate. Release of ^45Ca from prelableled calvarial bone(E18.5)in response to either 10^-7 M hpTH(1-34)or 20 ng/㎖ sRANKL was lower in gp130-/-calvarial bone compared to gp130+/+ calvarial bone (PTH 1.83±0.6 fold over basal in-/- vs 2.79±0.6 in +/+and sRANKL1.3±0.4 in -/- vs 2.79±0.6 in +/+ and sRANKL1.3±0.4 in -/- vs 2.0±0.4 in +/+,p<0.5). These result strongly support the hypothesis that PTH activates bone resortion,in part, by stimulating ostedtrophic cytokine secretiom from osteoblast/stromal cells, which tirggers gp130-mediated signaling for osteoclastic activation.

The results were as follows : 1. Soil arthropods consisted of Diptera (41 .2% ), Collembola(36%), Acarina(21.1%). and etc .. but the proportion in biomass of Diptera(90.5%) showed the highest of all, Nematodes fauna was composed of free living type(55.7 %), p.edato.5(33.') %), and plant parasites(11 .1 %). 2. Density and biomass of arthropods were highest In Ch?nmldong site(35.4 %), and of nematodes highest in the Gyehwa Ⅲ slte. 3. Arthropods(83.4%) and nematodes(65%) were found the most In the first layer. subsoil, i.e., 0-5in and 0-10 in, respectively but the density of arthropods was higher than that of nematodes 4. The population density of arthropods showed highest in April lowest In July, slightly increasing in October. And of the nematodes showed highest in October, lowest in January. 5. Density of arthropods In the first layer decreased gradually from January to July, and slightly increased in October. Of the nematodes. the highest In July and the lowest in April. 6. The correlations between arthropods and organic matter, pH, and temperature were significant , respectively but those of nematodes were significant In case of temperature only.
