This study was conducted to investigate wintering ecology and habitat using pattern of cranes for sound protection and management of the birds and their habitat near the Demilitarized Zone(DMZ) of Cheolwon, South Korea. Distribution of cranes seemed to be affected by road construction and human activity. Dried rice paddy was mainly habitat type of cranes in Cheolwon area. Gleaning was dominant behavior during day time. Ratio of alert was increased in afternoon. There was difference in time budget of behavior between red-crowned and white-naped cranes. For the stable wintering of cranes, minimum change of habitat, decrease of human disturbance and stable food maintenance would be needed in Cheolwon area.

저자등은 인슐린의존형 당뇨병환자에서 임신중에 병발한 당뇨병성 케톤산증을 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. IDDM is an autoimmune disease resulted from beta cell destruction and insulin deficiency, and developed mostly in children and puberty. Ketoaddosis remains one of the most senous complications that can occur in the pregnant diabetic. A 26-year-old woman, gravida 1, para 0, was admitted at 32 weeks gestation because of fever lasted for 6 days. She had been treated with insulin pump during the pregnancy. Blood sugar was well controlled before admission, and the etiology of her ketoacidosis was urinary tract infection and no insulin-intake. DKA was treated with fluids and intravenous insulin. Urinary tract infection was treated with antibiotics, based on culture test. Healthy newbom was later delivered by cesarean section due to fetal distress. We experienced a case of DKA in pregnant woman and report it with a review on literature.

The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test, and construction of simple silhouette figures. Then, camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection, which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

PKI core basic architecture for securing informations have to minimize client's burden to generations of authentication paths. Also, It must be solved the lack of timing and managements in the CRL, inter-operations among PKI domains according to its environment. To remove problems in the existing PKI, the validation server solves problems of timing for validating authentications and CRL using OCSP, supports inter-operation of PKIs, arid manages the authentication strategy of inter-domain. This paper proposes fast and effective the generation method of authentication path in the validation server. Because it generates previously and saves the authentication path, it can give the authentication path fast on requiring a validation. With saving the used path, it provides effective the authentication path by reusing the saved path.

Intake of soy protein may decrease the risk factors associated with cardiovascular disease in postmenopausal women. This study was designed to investigate the effects of isoflavone supplementation on serum lipids in 16 hyperlipidemic postmenopausal women. For this purpose, an intervention study was conducted for 12 weeks. Subjects were healthy, free-living women consuming habitual diets with 0.3 g/d of isoflavone. Food and nutrient intake was obtained by 24-hr recall method and anthropometric measurements were made. Systolic and diastolic blood pressure, total serum cholesterol, HDL-cholesterol and LDL-cholesterol were determined before and after the isoflavone supplementation. The results were summarized as follows. The average age, height, weight and BMI of the subjects were 65.3 years, 151.4 cm, 62.2 kg and 27.1, respectively. The systolic blood pressure and diastolic blood pressure were not reduced significantly with isoflavone supplementation. Total cholesterol (p < 0.001), HDL-C (p < 0.05), and LDL-C (p < 0.01) were significantly increased after isoflavone concentration. In conclusion, isoflavone supplementation was not effective to modify risk factors for cardiovascular disease.

李宗炫,安辛根,金學信 全北大學校 1988 論文集 Vol.30 No.-

In order to study the change of properties in Fe-13.3% Cr-0.37%C martensitic stainless steel for precision measuring gauge with the various heat treatments and plastic working, the change of micostructure, hardness and wear resistance were investigated. The results obtained in this experiment are as follows: 1. The high Cr alloy of 13% Cr martensitic stainless steel has selfhardening property which is not remarkably affected by the cooling rate, and also the hardness of this alloy was the highest value in the case of oil quenching after austenitized at 1000℃ for 1/3 hour. 2. The hardness and the corrosion resistance of low temperature tempering treatment are superior to high temperature tempering, especially the hardness of 200℃×2hr tempering treatment are superior to high temperature tempering, especially the hardness of 200℃×2hr tempering treatment in the case of air cooling after austenitized at 1050℃ for 1/3 hour is excellent. 3. The amount of retained austenite hardly existed in the case of air cooling after austenitized at 1000℃ for 1/3 hour, and the increase of hardeness with subzero-treatment is very small. 4. The property of hot working is good but the property of cold working is poor. And then, the secondary hardening with reheating treatment appeared at 400~450℃. 5. Bainite trasformation was occurred in the isothermal heat treatment, and the hardness and the wear resistnace of marquenching treatment are higher than martempering treatment. 6. The elevation of the wear resistance is proportional to the increase of the hardness obtained from the various heat treatments, especially the wear resistance of 200℃×2hr tempering treatment after air cooling is effective than after oil quenching and the wear mechanism is mainly a grinding abrasion.

The quality of childhood educare teacher is the most important element in evaluation of the quality of childhood educare. However, the current curricula for the childhood educare in colleges are operated individually without a standard curriculum and there are many problems in the certification system of childhood educare teacher. So, it is hard to discuss about the specialty of the childhood educare teachers. Hence, an immediate development of a standard curriculum which fully reflect the needs of the field is necessary to meet the demand of the times and to enhance the quality of childhood educare service by producing qualified teachers. To fulfill the aforementioned needs, the procedure of the DACUM Method which is useful in developing vocational training course is used in this study. And based on the results, a field centered curriculum of the Dept. Child Care and Education is developed by the job analysis of the childhood educare teachers and by collecting the needs of the field. Educare planning and activities, development and evaluation of the educare program, consultation and education of the family, utilization of the regional resources, and after-class guidance of the children were found to be the principal jobs of the childhood educare teachers.

Haeng-Shin Lee,Sohyun Park,Mi-Hyun Kim 한국영양학회 2014 Nutrition Research and Practice Vol.8 No.1

Water is essential for life and plain water instead of sugar-sweetened beverages is one approach for decreasing energy intake. Due to limited data on characteristics associated with water intake among Korean adolescents, this study examined associations of demographic and behavioral characteristics with plain water intake by using nationally representative sample of South Korean adolescents. The data (2007-2010 Korea National Health and Nutrition Examination Survey) for 1,288 high school-aged adolescents (15-18 years) were used. Multivariable logistic regression was used to calculate adjusted odds ratios (OR) for factors associated with low water intake (< 4 cups/day) and very low water intake (< 2.5 cups/day). Nationwide, 38.4% and 19.0% of adolescents reported drinking water < 4.0 cups/day and < 2.5 cups/day, respectively. The mean plain water intake was 5.7 cups/day for males and 4.1 cups/day for females. Females had significantly higher odds for drinking water < 2.5 cups/day (OR = 2.2) than males, whereas adolescents with low milk consumption had significantly lower odds for drinking water < 2.5 cups/day (OR = 0.7). Factors significantly associated with a greater odds for drinking water < 4 cups/daywere being female (OR = 2.8) and not meeting physical activity recommendations (≥ 20 min/day on < 3 days/week) (OR = 1.6). Being underweight, overweight, and obese were significantly associated with reduced odds for drinking water < 4 cups/day (OR = 0.7, 0.4 and 0.5, respectively). However, intake of soda, coffee drinks, fruits, vegetables, and sodium and eating out were not significantly associated with low or very low water intake. These findings may be used to target intervention efforts to increase plain water intake as part of a healty lifestyle.

This study was carried out to elucidate the relationship among exercise, bone mineral density and antioxidant enzyme activity of postmenopausal women. 60 women residing in the Iksan, Korea area were recruited. The questionnaires were designed to find out exercise habits. Bone mineral density (BMD) was measured by dual energy X-ray absorptiometry. Parameters of antioxidative capacity, including the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and total antioxidant capacity (TA) were analyzed in fasting blood. The mean age, height, weight, and BMI of subjects were 65.0 years, 151.1 ㎝, 59.5 ㎏ 26.0 m/㎏², respectively. The mean BMDs of subjects were 0.85 g/㎠ (lumbar spine), 0.6 g/㎠ (Femoral neck), 0.49 g/㎠ (trochanter), and 0.40 g/㎠ (Ward's triangle). There was a significant difference in BMD among different age groups (50's, 60's and 70's) showing lower value with increasing age (p<0.05). The mean SOD, GPx, and CAT activities were 138.5 U/mL, 1,273.8 U/mL and 314.3 kU/L respectively, and TA was 1.16 m㏖/L. TA of the group which exercised 3~4 times a week was significantly higher than those of the other exercise groups (p<0.05). The subjects with higher SOD activity also have a higher the T values in the lumbar spine, femoral neck, trochanter, and Ward's triangle. In conclusion, this study revealed that the levels of antioxidant enzyme activity were closely associated with the exercise status and bone mineral density in postmenopausal women.
