The purpose of this study was to examine the timing and sequence of growth and development velocity curves of some physique and physical fitness aligned on age at peak height velocity. The study design, the subjects, and the method used in cross-sectional investigation reported by Ministry of Physical Education and Youth of Korea(1989). According to the reported by Ministry of Physical Education and Youth, the subjects participated in goverment study were 7 through 50 over years of age who belonged to typical primary, junior and senior high school, college and adult, and about 550 males and 550 females in each age. Thus, the total sample size were 6,316 males and 6,316 females. Grand total was 12,632. For physique measured, 2 body linearity items ; body height and sitting height, 5 body bulk items ; body weight, chest girth and 3 site skinfold thickness items were selected. For physical fitness measured, 8 items such as grip strength, sit-ups, 10m shuttle run, standing long jump, 50m dash, long distance run, eyeclosed foot balance and trunk flexion were selected. Measurements were actually worked out in April through July, 1989. The mean and the standard deviation were computed for each itesm, each age, and each sex, respectively. The growth and development velocity magnitudes of some physique and physical fitness in this study were calculated by personal computer. The conclusion obtained as follows. 1. Ages at PHV occurred earlier about 3years than males on the average. 2. Maximal annual increments (PV) in body weight, chest girth and sitting height appeared to coincide with PHV in males, but, to about 1 and 2 years after PHV in females. 3. Two occurrence of peak velocity gained in the chest girth for males and 3 site skinfold for females. In contrast, peak velocity of triceps skinfold was not appeared in males. 4. Peak velocities of grip strength and trunk flexion occurred about 1 to 2 years after PHV in both sexes. Peak velocities of 50m dash and long distance run occurred about 1 to 2 years after PHV in males. 5. Peak velocities of sit-ups, standing long jump and eyeclosed foot balance occurred about 1 to 2 years before PHV in both sexes, respectively. 6. Peak velocity of 10m shuttle run was not occurred in both sexes, peak velocity of 50m dash was not occurred in females. 7. Generally, peak velocities of physique and physical fitness occurred earlier about 1 to 3 years in females than in males.

Plasma fibronectin is an α₂-glyoprotein, which is produced by vascular endothelial cells. Raised level of plasma fibronectin has been observed in diabetic patients particularly in the presence of microvascular complications. However, no available data exist about urine level of this glycoprotein in diabetic patients. We measured urine fibronectin level by ELISA methods in 54 diabetic patients who have microvascular comlications or not. The following results were obtained. 1) Urine fibronectin level(㎍/g creatinine) in diabetic group(1740.0±678.0) is increased compaired with those in normal control group(471.0±59.0). but this results were not significantly different among two groups(P>0.05). 2) Urine fibronectin level(㎍/g creatinine) was significantly increased in patients with nephropathy (6188.0±3144.0) compared with those in normal control group(471.0±59.0) and patients without nephropathy(645.0±251.0)(P<0.001). 3) There were a significant correlation between BUN, creatinine, creatinine clearance, 24hr urine total protein and urine fibronectin level in diabetic patients. Our data suggest that urine fibronectin excretion level might be used as a sensitive guide for diabectic nephropathy.

본 연구는 2014학년도부터 2016학년도까지, 영어과 중등교사 임용시험에서 출제된 1차 문항을 분석한 것이다. 연구방법으로는 지난 3년간 출제되었던 67문항을 수집하였고, 평가영역 및 평가 세부항목, 그리고 문항 유형별에 따른 출제빈도와 배점비율을 분석하였다. 출제문항을 분석한 결과, 평가영역별 출제비율은 영어교육학이 40%가 넘는 비율을 차지하였고, 일반영어의 비중은 급격하게 축소되고 있는 경향을 보였다. 이는 우수한 영어교사의 전문성을 평가하고 선발하는 데 기본 요건을 충족한다고 볼 수 있으나, 각 영역의 출제빈도와 비중이 지난 3년 동안 매년 변화하는 것은 수험생들에게 혼란을 가져올 수 있음을 시사한다. 각 영역의 세부항목별 분석에서는 출제 내용이 일부 평가내용요소에 편중되어 있는 경향이 있어, 향후 출제에서 고려해 봐야 할 문제라고 보인다. 마지막으로 문항 유형 분석에 따르면, 서술형과 논술형 문항의 등장은 객관식 문항의 한계점을 보완할 수 있다는 점에서 긍정적인 변화이나, 단편적인 지문 이해력을 확인하는 문항보다는 수험자의 심층적인 사고력과 응용력을 평가할 수 있는 문항의 개발이 필요하다고 할 수 있겠다. 이러한 분석 결과를 토대로 영어과 임용시험의 개선안에 대해 논의를 하였다. This article examines the test items from the written component of the secondary school English teacher recruitment exam. Focusing on the years from 2014 to 2016, the analysis was based on a collection of 67 test items. A frequency count was conducted to determine the different question types as well as the representation of each field and sub-fields of English education. The results reveal that out of all fields, questions regarding English educational knowledge represented more than forty percent of the test items while questions requiring general English knowledge vastly decreased. The exam appears to fulfill the basic criteria for evaluating prospective English teachers, but the sudden changes in required content knowledge can cause confusion among examinees. The sub-fields of English education were also unevenly distributed, suggesting the need for a consistent guideline that secures balanced test content. Lastly, an analysis of the question types shows open-ended and essay-type question items as a measure for overcoming the limitations of multiple choice questions. Nevertheless, some of the questions still remained at the level of assessing simple comprehension rather than the examinees’ abilities to synthesize, critique, and apply professional knowledge.

Garlic (Allium sativum L.) is a widely distributed plant used in all parts of the world not only as a spice but also as a popular remedy for several thousand years Recent studies have shown that garlic components may regulate the many metabolism in liver. Therefore, the present work was undertaken to study the effect of garlicjuice, allicin fraction and heat-treated allicin fraction on the hepatic glutathione s-transferase and glutathione peroxidase which protect against toxic compound and lipid peroxide in liver. The results obtained were summarized as follows. By the treatment of garlic juice, glutathione s-transferase and glutathione peroxidase activity was increased in hepatic cytosolic fraction compare with control group. The enzyme activtiy is more increased by treatment with boiled garlic juice compared with fresh garlic juice in rats. The effect of allicin fraction and heat-treated allicin fraction on the hepatic glutathione s-transferase was observed that these components inhibited the enzyme activity in vitro, whereas the enzyme activity was strongly inhibited heat-treated allicin fraction than allicin fraction. These observation led us to conclude that the garlic components which are a stable substance in heat may regulate the hepatic glutathione s-transferase and glutathione peroxidase activity.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

Ozone is very effective in acute and chronic viral disease as a virucidal agent and in improving the general health of the animals. The effects of ozonized water supply against Cryptosporidium baileyi was studied in 2-day-old chicken. After oral inoculation of chicken with 1×10^6 oocysts, ozonized water(0.5ppm) and tap water were supplied to experimental and control group, respectively. The prepatent period of both group was 6 days postinoculation(PI). The patent period of experimental group was shorter(6-18 days) than that of control group(6-22 days). The number of oocysts in the feces were maximum on days 11 PI, indicating 1.99×10^6 oocysts/experimental chicken and 6.00×10^6 oocysts/control chicken. The number of discharged oocysts during experimental period was higher in control group than that of experimental group. In the view of febric bursa sections on 7 days PI, the number of endogenous development of C baileyi was smaller in experimental group that in control group. This results indicate that the autoinfected sporozoite were damaged by ozone. The ozonized water supply to chickens is alleviation cryptosporidiosis.

박규태,이상범,류근호 연세대학교 산업기술연구소 1985 논문집 Vol.17 No.1

Dataflow computers exhibit a high degree of parallelism which cannot be exploited in a conventional von-Neumann architecture framework. Among the well-established dataflow computers is an MIT machine, whose driving force is heavily based upon data-driven computation. This paper describes a new dataflow machine which further improves the relatively poor performance exhibited by the MIT machine. Our machine is designed by adding the notion of demand-driven computation to the MIT machine structure.
