  • This study was carried out to investigate the nutritional and physical status of children, aged 11 and 12 years, living in Haenam Koon (living at home) and in Mokpo City (living in an orphan asylum) located in Chonnam during the period of August 2 nd to 9 th in 1984. The mean values of height, chestgirth, arm circumference and head circumference between both groups of living in the rural area and in the city orphan asylum were not statistically different and similar to Korean Growth Standard. Exceptionally, the values of height and weight of male living at home in the rural area were lower than Korean Growth Standard (p<0.01). The weight of male living in the city orphan asylum was higher han that of male living at home in the rural area (p<0.01), and the skin fold thickness of female living at home was higher than that of male living at home (p <0.01). The physical indices of children living in the city orphan asylum were more or less higher than those of living at home in the rural area, but the relative weight of male was only significant (p<0.05). The animal protein intake was $8.4{\sim}8.6%$ of total food intake of living at home in the rural area and 6.2% in living in the city orphan asylum. The intake of legumes of children living in the city orphan asylum was more two times than that of living at home in the rural area, but overall fruit intake of living at home was more about two times than that of living in the city orphan asylum. The average intake of all nutrients except thiamine and niacin was lower than RDA. Especially the calcium intake of children in both groups was the lowest of all nutrients ($28.9{\sim}40.6%$ of RDA). Children living at home in the rural area had significantly higher intake of fat and ascorbic acid than children living in the city orphan asylum (p<0.01).

  • The aims of this study were to determine the effects of feeding medium-roasted soybean meal (SBM) and corn dried distiller's grains with solubles (CDDGS) in dairy cows on milk production and income over feed costs. A randomized complete block design experiment was conducted with 24 crossbred multiparous Holstein Friesian dairy cows in early- and mid-lactation. Four dietary treatments were as follows: basal diet without feed substitute (Control), 7.17% dry matter (DM) roasted SBM replaced for concentrate (R-SBM), 11.50% DM CDDGS replaced for concentrate (DDGS), and 3.58% DM roasted SBM plus 5.75% DM CDDGS replaced for concentrate (SB-DG). The roasted SBM was produced using a medium-heated treatment at $100^{\circ}C$ for 180 min. Dry matter intake was not affected by feeding high rumen undegradable protein (RUP) sources, but the replacement of roasted SBM and CDDGS for concentrate significantly improved (p<0.001) RUP intake (0.90, 0.86, and 0.88 kg/d corresponding to R-SBM, DDGS, and SB-DG) compared to the control (0.61 kg/d). Feeding roasted SBM and CDDGS alone or in combination had no significant effect on milk composition of dairy cows (p>0.05), whereas milk yield was significantly increased by 3.08 kg/d in the SB-DG group relative to the control group (p<0.01). Net income was meaningfully increased (p<0.05) from 4th week post feeding, the SB-DG group reached the greatest net income ($3.48/head/d) while the control group had the lowest value ($2.60/head/d). In conclusion, the use of CDDGS alone or in combination with medium-roasted SBM as substitute for concentrate in lactating dairy cattle diet led to improved milk production and net income over feed costs without affecting total dry matter intake and milk composition, while feeding medium-roasted SBM seemed to show intermediate values in almost parameters.

  • To evaluate the unit load generation and discharge, pig cage test was conducted. Feed intake, drink amount, and urine generation increased growth stage (heavy weight) of the pig more great. However, the sum of the urine and manure did not show a significant difference in the growth stages of pigs. Because of the limit of the experiment, e.g., research period, high pigpen temperature, breed-related stress and etc., it could not be derived the results of the four seasons. Therefore, in order to generalize the results, the feed intakes were calibrated using a NRC (National Research and nutritional requirements of pigs from the Commission) standards. The finalized unit load generation and generation amounts of manure and urine were estimated at BOD 104.1 g/head/d, T-N 21.2 g/head/d, T-P 4.9 g/head/d, manure 0.96 L/d, urine 1.66 L/d with consideration of revised feed intake. Compare to the former research results of MOE (Ministry of Environment, 1999) and NIAS (National Institute of Animal Science, 2008), the generation amounts of manure and urine were similar to the NIAS's values. In case of unit load generation, BOD and T-N were almost similar in all of them. However, the T-P unit load generation of MOE was more difference, e.g., 2.5 times high, compare to this study.

  • Background and Objectives: This study aimed to analyze risk factors for positional vertigo (PV) and the influence thereof on daily life and subjective quality-of-life (QoL). Subject and Methods: A cross-sectional study was conducted using data of the 2010 Korea National Health and Nutrition Examination Survey. The study population consisted of 1,274 individuals aged >40 years for whom complete dizziness-related data were available. Blood and urine tests were performed, and nutritional intake, QoL, and subjective health status were measured using a questionnaire. The associations between PV and blood/urine test data and nutritional intake were evaluated via multiple logistic regression analysis. Results: A history of PV within the previous year was reported by 98 individuals (7.7%). Advanced age and female gender were both significantly associated with such a history. Serum hemoglobin, creatinine, and triglyceride levels correlated significantly with a history of PV. Carotene, vitamin A, and vitamin B2 intakes were significantly lower in individuals with PV. Multivariate analysis revealed that only age was significantly associated with a history of PV (p=0.003). Although subjective health status score was not significantly lower in subjects with PV, subjective impairments in mobility, self-care, the performance of usual activities, and anxiety/depression were more prominent in individuals with PV. A fall history and limitations of activity were also significantly higher in individuals with PV (p<0.001 and p=0.003, respectively). Conclusions: Age was a risk factor for PV, which affected most QoL parameters, fall frequency, and the performance of normal activities.

  • Objectives : In $CO_2$ laser surgery for supraglottic cancer, neck dissection is generally done in second stage. We investigated simultaneous neck dissection with primary resection could be available in laser supraglottic surgery. Material and Methods : We analyzed 13 patients with supraglottic cancer who were treated with transoral supraglottic laryngectomy and simultaneous neck dissection from 2001 to 2007. Tumor stage, extent of laser surgery, histological results, survival rate, local control rate, complications, and functional results were reviewed. Results : 5-year local control rate, survival rate and disease specific survival rate from the neck was 100%, 69.9%, 100% respectively. Tracheotomy was done in all 13 cases. One patient had a long tracheotomy indwelling (191 days). In the rest of 12 patients average decanulation time was 7.4 days(1-22 days). Nasogastric tube was inserted in 5 cases, and average oral intake was possible in 3.5 days(1-16 days). Average hospital days was 29.7 days. There was no serious complication associated with neck dissection. Conclusion : Simultaneous neck dissection with primary laser resection for supraglottic cancer is oncologic sound and can be performed without significant surgical morbidity.

  • The swirl ratio of a charge in the cylinder was estimated by calculating the ratio of the rotary speed of charge which could be simulated from the rotary speed of paddle in the swirl measurement apparatus, to the engine speed which could be calculated by measuring intake air flow rate. The automation of the swirl ratio measurement for cylinder head was achieved by controling both valve lift in cylinder head and a suction pressure of surge tank using two step-motors. The number of measurement position for calculating mean swirl ratio was varied by adjusting the interval of valve lift. The mean swirl ratio with varying the number of measurement position showed nearly constant value. Two measurement methods for measuring the swirl ratio were compared, one was to control the suction pressure of the surge tank with PID (proportional, integral, differential) mode with by-pass valve controlled by the step motor and the other did not control the surge tank pressure by fixing the by-pass valve. The difference of the mean swirl ratio between the two measurement methods showed nearly constant value with varying the number of measurement position. This means that the w/o PID control method could be preferred to the PID control method which has been used, due to the simpleness of the swirl measurement.

  • A nutrition survey of 128 perschool children, 4 to 6 years old, in the Saemaul Youlgok day care center, located in one uplane, overpolulated, poor area of the city of Seoul, sponsered by the Korean Red Cross Society, was undertaken between August 21 and 31, 1984, to investigate dietary and nutritional status. RESULTS: Mean values of height, weight, arm circumference, girth of chest, and head circumference ranged from 95 to 100% of KIST mean. However, 4.8~14.2% of the subjects were assessed as undernourished in terms of 'weight for height'. Mean hemoglobin vcalue was 12.1±0.7gm%, and mean hematocrit value was 38.5±2.2%; 4.1% of the subjects were proven to be anemic according to the criterion of hemoglobin established by the ICNND. Mean urinary urea nitrogen/creatinine ratio was 11.4±3.8. Regarding mean energy and nutrient intake, the following percentages had intakes below two-thirds of the 1985 RDAs: 28.8% of children, for protein; 48.8% of children, for iron; and 28.8% of children, for calcium. About 25% of children had vitamin A intake below one-third of the recommended allowance. Carbohydrate provided 71% of total energy intake; protein accounted for 13%; fat provided 16%. Energy intake was divided among breakfast, lunch, dinner and snacks in a percentage ration of 19:26:21:34. The lunch, and snacks which were served at the day care center provided 36.5~79.1% of daily energy and nutrient intake. The survey clarified that the day care feding largely supplemented the inadequate dietary intakes of these young children at home. According to factor analysis of energy and nutrient intake, there were two factor groups : the first factor group, for energy, protein, carbohydrate, iron and niacin, mainly provided by grains; and the second factor group, for calcium, vitamin A, thamin, riboflavin and ascorbic acid, provided by vegetables, fruits, milk and milk products. The survey also revealed significant correlation coefficients between family factors such as family income, educational level of parents, and number of children; and dietary or nutritional status of the subjects.

  • A nutrition survey of 152 children , in the kindergarten attached to a proivate elimentary school of Pusan, was undertaken between Dec. 1 and Dec.14, 1993, to investigate dietary intake and nutrition status. The results are summarized as follows. 1) Compared with the Korean child development standard, their development conditions showed 113.1% , 102.2% , 103.3%, 101.75 in weight, height, head and chest, respectively. 2) By the standard of WLI(Weight Length Index) , proper to the children between age 4 and 6 , there proved to be 25% overweight and 4% obesity, 25% overweight and 19% obesity , 28 overweight and 26% obesity in 4-year-old, 5 year-old, and 6 -year-old children, respectively. 3) The children between age 4 and 6 averaged 37.6% in hematocrit and 12.4-12.8 5 in hemoglobin. these values were higher than those of the Korea child development standard. but the numbers of erythocyte, leucocyte and platelets were normal . Only a single child was considered suffering from aenmia . The 8% of them were over 200mg/이 in cholesterol, dangerously approaching the atherosclerosis. The 31% averaged 120mg/이 in triglyceride . And the 6% proved 100mg/이 in blood glucose when hung교. So it came out that not a few children had some factors dangers to diabetes, atherosclerosis and heart diseases : complications arising from obesity. 4) The intake of nutrients , except the 4-year-old children , ranged 108.4% to 2665 from the recommended value. The rates of carbohydrate, fat and protein to be much correlation among total intake of nutrients, development , results of blood test and WLI. The degree of obesity was proportionate to the intake of nutrients.

  • Most of the intake facilities of small agricultural reservoirs are conduits and they are regarded as serious defects due to the structural weakness that penetrates the body of the dam, and countermeasures are needed. This study suggests the application method of siphon type water intake facility by hydraulic model test and physical scale model test of siphon type water intake facility which has high safety and easy maintenance. Experimental results show that sufficient flow rate can be secured for the purpose of intaking water according to the differential head between the reservoir and the discharge part, and the flow rate can be controlled by the valve. The negative pressure was -31.5 kPa, and vibration and noise did not occur during the operation of the siphon. The maximum flow velocity in the discharge outlet was 1.11 m/s which meets the criterion for irrigation canals. Therefore, scour risk would be very low. As a result of the inflow distribution experiment, even if the inflow part is separated by only about 0.8 m, the flow velocity is remarkably decreased, so that the clogging by debris would not appear. When the pump was operated only once for the first time and the inside of the siphon was filled with water, continuous operation was possible by only valve operation. The results of this study are expected to be used for the design guidelines of the water intake facilities and improve safety and maintenance convenience of agricultural reservoirs.
