  • Two 3-month old Wistar Strain male rats (weights was 270g and 340g respectively) were used as samples in order to determine the daily excretion of thiamine contained in urine and feces by the thiochrome reaction. The results were as follows. 1. Daily excretion of urine was 5,2 cc per 100 grams of body weight and that of thiamine was $18.65\;{\gamma}$ per 100 grams of plasma. 2. Daily excretion of feces was 2.4 grams per 100 grams of body weight and that of thiamine was $7.24\;{\gamma}$ per 100 grams of plasma. 3. Daily excretion of thiamine contained in urine is about twice the amount of thiamine excretion contained in feces. Thus, it can be concluded that more of the excretion of thiamine was mainly excreted through urine.

  • The purpose of this study was to investigate and compare the biomechanical properties of orthodontic rubber elastic materials. Latex bands, nylon-covered elastic threads and polyurethane-based elastic modules, delivering $205{\pm}10$ grams force at 30mm stretching state were selected and stored separately in 3 environments-air ($22{\pm}3^{\circ}C$), distilled water ($37{\pm}1^{\circ}C$), or natural saliva ($37{\pm}1^{\circ}C$). And, the amount of remaining force and permanent elongation of each sample were measured on Instron at interval of 1 hour, 6 hours, 12 hours, 24 hours, 1 week, and 2 weeks. So the data derived were analyzed statistically. The results were as follows: 1. Force decay and permanent elongation of all materials increased with time lapsed; elastic module, latex band and nylon-covered elastic thread in that order of the amount of force decay; elastic module, elastic thread, latex band in that order of the amount of permanent elongation. 2. Among environmental conditions, force decay and permanent elongation in natural saliva, most increased, and those in air, least increased. 3. There was a negative correlation between force decay and permanent elongation. 4. Force decay and permanent elongation were most affected by the material itself, time and environments in that order. 5. After 24 hours in saliva, the percentage of remaining force in elastic module was 51.9% (107.37grams); in latex band, 83.2%(172.62grams); in elastic thread, 85.0%(179.25grams). After 2 weeks in saliva, the percentage of remaining force in elastic module was 42.9%(88.75grams); in latex band, 74.5%(154.50grams); in elastic thread, 77.6%(163.75grams).

  • Existing techniques for string similarity search first generate a set of candidate strings and then verify the candidates. The efficiency of string similarity search is highly dependent on candidate generation methods. State of the art techniques select fixed length q-grams from a query string and generate candidates using inverted lists of the selected q-grams. In this paper, we propose a technique to generate candidates using variable length grams of a query string and develop a dynamic programming algorithm that selects an optimal combination of variable length grams from a query string. Experimental results show that the proposed technique improves the performance of string similarity search compared with the existing techniques.

  • Kojedo is the second largest island in Korea and a total population of 115,500 is living on the island of 394.69 sq. km. Under the direction of three nutrition professors, nutrition surveys in two villages in Kojedo, namely Siljun Ri in Hachung Myon and Soowol Ri in Shinhyun Myon, were carried by 30 college senior students majoring in nutrition from August to 20 August 1977. From a total of 176 households of the two villages, 67 households were randomly selected and 390 family members of the households were subjcets of the nutrition surveys. The precise weighing method was used in evaluating the kinds of foods and nutrient intakes of the subjects for three consecutive days. Thirty-seven pre-school children aged between 3 to 6 years and 27 fertile women were examined for biochemical findings and physical status. The main purposes of the surveys are to provide baseline data on nutrition in Kojedo Island for the Kojedo Community Development Project and to compare the nutritional status of the villages of Siljun Ri and Soowol Ri. Siljun Ri is located in the pilot project area of the Koiedo Community Health Project sponsored since December 1970 by the Christian Medical Commission of the World Council of Churches. While Soowol Ri is a control village for comparison. The results obtained are summarized as follows: Food Intake The average food intake per person per day in Siljun Ri, 1064 grams (91.7% in vegetable foods and 7.6% in animal foods) was 90 grams more than that of Soowol Ri, 974 grams (92.8% in vegetable foods and 5.9% in animal foods). However, the food intake per pre-school child in Siljun Ri, 485 grams (92.6% from vegetable foods and 6.4% from animal foods) was 21 grams lower than that of the Soowol Ri, 506 grams (88.5% from vegetable foods and 6.5% from animal foods). The average intake of beans was 16 grams(1.5% out of the total food intake) in Siljun Ri and 21 grams(2.2% of the total food intake)in Soowol Ri. The villagers should be guided for more consumption of soybeans to improve the quality of protein intake from vegetable foods. Nutrient Intake The adult intake in Siljun Ri and Soowol Ri were 2,529 kcal and 2,511 kcal respectively. The average energy intake of pre-school childen in Siljun Ri was 948 kcal and that for adult and 1,500 kcal for childen aged between 4 to 6 years-given by the Korea FAO Association, the diets in both villages were not adequate. Average daily protein intake of the subjected adult in Siljun Ri was 78.4 grams and that of Soowol Ri was 76.2 grams, while pre-school children took 30.7 grams in the former village and 31.7 grams in the latter village per child per day. The protein intake in both villages were lower than the recommended allowances, 80 grams for adult and 45 grams for $4{\sim}6$ years childen, and animal protein intake of the all subjects was very much lower than the RDA. The main charecter of the diet has been found low in quality of protein and high in carbohydrate. The calcium intakes of the pre-school children in both villages, 251.9 milligrams in Siljun Ri and 218.8 milligrams in Soowol Ri, were very much lower than the recommended allowance of 500 milligrams per day. It is apparent that the diet for children should be supplemented with calcium. Among the vitamin group, the daily average intakes of vitamin A and $B_{2}$(thiamine), $B_{2}$(riboflavin), C(ascorbic acid), and niacin were not adequate for the children in both villages. Especially the intake of riboflavin, 0.4 milligrams in both village children, was much lower than the RDA, 0.9 milligrams per day. Physical Characteristics Average height, weight, chest and head circumference of the pre-school children in both villages were similar to those of the Korean standard given by the Korean Paediatrics Association except that the average height of pre-school boys in Siljun Ri was 8 cm higher than the Korean standard of 105 cm. The mean values of upper arm circumference and skinfold thickness of pre-school boys in both villages were the same, 15.4 cm for upper arm circumference and 6.8 mm for skinfold thickness, but the mean values of those of the girls in Siljun Ri were higher than those of pre-school grils in Soowol Ri. Biochemical Findings Avera ge hemogobin value of boys and girls in both villages was the same, 11.1 grams per 100 ml of blood. The incidence of anemia (Hb value below 11g/100ml) was similar in both viltagesr 36.4% for boys and 50% for girls in Siljun Ri and 37.5% for boys and 50% for girls in Soowol Ri. Average hemoglobin values of fertile women were 10.7g% in Siljun Ri and 10.8% in Soowor Ri. The incidences of anemia(Hb valre brlow 12g/100ml) were 100% in Siljun Ri and 86.7% in Soowol Ri. The anemia of these subjects may be caused mainty low intake of good quality protein and iron intake from vegetable food. Recommendation In general, the nutritional status of a community health pilot village is not higher than that of control village due to the lack of nutrition improvement guldance services. Nutrition education should be delivered to the villagers as a main part of the health education artivities. The emphasis should be on building better health through bttter food habits and better food production as well as on preventing malnutrition and diseasrs. It can be an invaluable part of community developnent. Since nutrition is considered to be at least one-half of MCH care, no village or home visits should be made without careful provision for teaching and demoastrating something simple and practical on nutrition. The nurse, midwife, and village health worker should be the chief promoters of nutrition.

  • LOw Frequency Analysis Recording (LOFAR) and Demodulation of Envelop Modulation On Noise (DEMON) grams are bearing-time-frequency plots of underwater acoustic signals, to visualize features for passive sonar. Those grams are characterized by tonal components, for which conventional data coding methods are not suitable. In this work, a novel LOFAR/DEMON gram compression algorithm based on binary map and prediction methods is proposed. We first generate a binary map, from which prediction for each frequency bin is determined, and then divide a frame into several macro blocks. For each macro block, we apply intra and inter prediction modes and compute residuals. Then, we perform the prediction of available bins in the binary map and quantize residuals for entropy coding. By transmitting the binary map and prediction modes, the decoder can reconstructs grams using the same process. Simulation results show that the proposed algorithm provides significantly better compression performance on LOFAR and DEMON grams than conventional data coding methods.

  • Objectives : Korea and China are applying different conversion standards for weight in traditional medicine books. This study aims to research and suggest how to convert the units of weight in old traditional medicine classics into the contemporary unit of grams. Methods : Historical documents of Korea and China were used to review the process in which weights and measures changed in each country and the manners in which the Chinese units of weight were introduced to Korea. Results : Weights and measures changed with time. They became almost standardized by the period of Song in China, when coins played the most crucial role, and it was introduced to Korea. Donggaryang, the standard container for weights and measures in ancient China, Gaewontongbo, a coin in Tang, Sangpyeongtongbo, a coin in Joseon, and a scale in Joseon were used as strong foundations for conclusion from literature review. Weight of a 1-don(coin) in the time a traditional medicine books were written was used as a unit of weight in those books. Sangpyeongtongbo, a 1-don coin in Joseon, weighs 4 grams on average. Conclusions : Since the current conversion of 1-don coin into 3.75 grams is not supported by literature review, it is suggested that 1-don(coin) as a unit of weight in traditional medicine books of Joseon, may be better converted into 4 grams, while that of China is converted to 3.73 grams.

  • Recently this writer has conducted a comprehensive survey of 38 private businesses where group feeding is practiced, with a view to determining the condition of nutrition intake by the blue collar workers of these businesses firms as well as gaining an indication of their facilities management along with their sanitary precautions. The survey has revealed, among others, a number of interesting data such as shown below. 1. There are a total of 1,054 workers being fed in groups daily at each of the above business companies, with only one nutrition specialist regardless of the number of workers to be fed or the number of times they are fed daily. The average number of cooks comes to 2.7 persons per 100 workers, while 42.2% of the companies provide four meals a day including mid-night supper, with the result that the workers are fed 3.13 times a day on an average. 2. The average feeding cost amounts to 151 won per meal per person, of which 86 won is payed by the workers themselves and 115 won by the companies involved. 3. The average fbod intake has been found to be 490 grams which can be further broken down into 44grams of animal food and 446grams of vegetable food. These figures are higher than those revealed by the 1975 investigation of the nation's average nutrition intake. 4. The survey also shows the daily calorie consumption per person to be as high as 896 calories including 37 grams of protein which is further broken down into 11 grams of animal protein and 26grams of vegetable protein. With respect to other types of nutrients excepting Vitamin-A, the companies concerned are believed to prorids more than what the survey of the nation's nutrition has revealed or the amount recommended by Korea FAO assoc!ation as desirable. 5. As for facilities management, there is still much room for future improvement. Some 97.4% of the companies surveyed are not equipped with the steam table, which indicates lack of concern along this line as well as a very how degree of equipment utilizations. Distribution of the food in the dining room is generally depedent on self-service method. 6. Speaking of sanitary precautions taken by those businesses involved, some 76.3% are found to have their compounds haunted by rats and other insects. Some 73.7% of them are dependent on boiling method for disinfection of kitchen utensils, which is conducted by 50% of those industries only two or three times a week. It seems hardly feasible to conduct disinfection everyday.

  • A white light flare was observed at the limb on 16 August 1989 in He 10830 ${\AA}$ spectra, H$\alpha$ slit jaw photo-grams, and white light filter-grams of ${\lambda}=5600{\AA}{\pm}800{\AA}$. The kernels of the white light flare are not spatially related with Ha brightenings, suggesting that the flare energy would be released at the photosphere.
