  • 우리국민의 영양소섭취상태는 실제의 영양량섭취상태조사로나 또는 식량수급표로보나 곡류, 그중에서도 백미의 섭취량이 가장 많고 그다음이 맥류이며 기타 잡곡류의 섭취량이 적으며 동물성 식품의 섭취는 매우 적다. 이와 같이 곡류위주의 식생활구조는 영양학적으로나 양곡정책 나아가서는 국제 경제적으로 많은 문제점을 제기하고 있다.

  • The distribution characteristics of incised meander river are analysed concerning topography, geology, stream order and altitude. Additionally geomorphological development of the Korean peninsular is considered with incised meander. The main findings are as follows: 1. The incised meander is intensively distributed on the west and north slope of T'aebak and Sobaek mountain range, but sparsely distributed on the opposite slopes. 2. Geologically, the occurrence rate of incised meander is high orderly as follows: Joseon supergroup, Pyeongan supergroup, Daedong supergroup metamorphic rock, Gyeongsang supergroup, and granite. The incised meander is developed well on the following conditions: hard rocks against weathering, stratified structure, geologic arrange across the river channel and contacting zone of geological formations. 3. The higher stream orders are, the higher occurrence of incised meander is. 4. Comparing the altitude of present river bed with the summit level of restored map, it is supposed that the incised meander rivers have been dissected about 300-500m down ward. 5. Considering the distribution characteristic of incised meander, it is suggested that not only T'aebak mountain range but Sobaek mountain range is the axis of asymmetrical up-warping in the Korean peninsular. 6. Considering the distribution characteristic of incised meander on the restored map and the stream order, it seems that present incised meander channel was inherited from antecedent meander river that had flowed on High and Middle level erosion surface. But the channel pattern has been modified.

  • Photostimulated luminescence (PSL) analysis was applied to determine whether some agricultural commodities of Korean and Chinese origins have been irradiated or not. Cereals (brown rice and buckwheat) and legumes (soybean, peanut, fed bean and mung bean) were exposed to gamma irradiation at 0.5 ∼4 kGy The Korean garlic was irradiated at 0.05 ∼0.5 kGy. Cereals and mung bean were tool applicable to the PSL measurement, showing the intermediate values between the lower (700 photon counts, negative) and the upper threshold values (5,000, positive), however PSL values determined for soybean, peanut, red bean and garlic were suitable for being discriminated between nonirradiated and irradiated samples. There was no significant difference in PSL properties accgrding to the sample origins.

  • A curd yogurt was prepared from milk added with skim milk powder or four kinds of cereal. Addition of cereals markedly stimulated acid production by Leuc. mesenteroides. The acidity significantly increased during fermentation by Leuc. mesenteroides for 30 hours while pH significantly decreased during fermentation. The number of viable cells markedly increased until the first 12 or 18 hours of fermentation by Leuc. mesenteroides. Acetaldehyde, acetone, ethanol, diacetyl, butanol and acetoin in curd yogurt were detected by gas chromatographic analysis. Among these compounds, acetaldehyde, ethanol, diacetyl and acetoin were produced during fermentation by Leuc. mesenteroides.

  • A curd yogurt was prepared from milk added with skim milk powder of four kinds of cereal. The effect of cereals at 2%(w/v) level on acid production by lactic acid bacteria in milk was investigated. The effect of cereals on quality of curd yogurt (apparent viscosity, sensory property) was also examined. Addition of cereals markedly stimulated acid production by lactic acid bacteria. Among three organisms tested, L. acidophilus produced more acid than others. Apparent viscosity of curd yogurt added with corn was the highest while that with barley was the lowest. Curd yogurt fermented with L. acidophilus showed characteristics of thioxotropic flow. Apparent viscosity of curd yogurt added with cereal markedly increased between 6 and 24 hours of fermentation. Sensory property of curd yogurt added with wheat was judged as better than reference sample, but that with barley was lodged as the worst among all samples.

  • In this study, dietary fiber contents in cereals and pulses were determined by Mongeau-Brassard method to compare those to the AOAC officied method. The average total dietary fiber (TDF) contents by AOAC official method were 3% for cereals and 21% for pulses. The average ratios of soluble dietary fiber contents to TDF contents were 40% for cereals and 43% for pulses. The differences between TDF values (dry matter basis) by two methods were 0.1%-1.0% for cereals and 1.0-7.0% for pulses. The differences between two methods were caused by residual protein in fiber by Mongeau-Brassard method and by residual starch in fiber by AOAC official method. TDF\\error boundary values by Mongeau-Brassard method were little higher than those by AOAC official method. But seven foods except highly milled rice, brown rice and mungbean were F/Fc>1. Therefore, Mongeau-Brassard method was evaluated as precise as AOAC official method.

  • In order to evaluate their possible subacute toxicity, the male and female of SD rats were given to 30 kGy irradiated cereal powders for three months. During the experimental periods, appearance, behavior, mortality, body weight, organ weight, and food consumption of rats fed the 30 kGy cereal powders were not affected compared to the non-irradiated control. In urine analysis, histopathological examination, hematological as well as in serum biochemical findings, no significant differences were found between the rats administered with non-irradiated control and 30 kGy cereal powders for three months. These results indicate that cereal powders irradiated at 30 kGy did not show any toxic effects under these experimental conditions.

  • The contributing ratio and type of carbohydrate supply as an energy source were investigated for the period from 1974 to 1984. The major component of energy in food groups was cereals, but the cereals and potatoes were decreased almost steadily. The share from sugars, meats, oils, milk and eggs has been doubled with per capita income increase. Vegetable foods were consisted of 90% of total energy supply. In 1984, approximate 70% of the energy supply of cereals was provided by rice. The type and composition of carbohydrate supply were influenced by per capita income and food processing technology. Less carbohydrate intake and the ratio of complex carbohydrates to refined sugar and simple sugars also decreased.

  • The aim of this study is to investigate distribution characteristics of incised meander cutoff in Gyeonggi and Gangwon Provinces of Central Korea. The density of meander cutoff is highest in the mountain rivers including Naerin and Dongdae flowing on Jeongseon-gun and Inje-gun of Gangwon Province. Most of meander cutoff process has been occurred repeatedly during the Quaternary period, especially concentrated in the period of climatic change between glacial and interglacial stages. In the aspect of the lithology, the density of cutoff is highest in sedimentary rock, but lowest in igneous rock. As for geological structure, its frequency is high at $11{\sim}20km$ westerly away from the Taebaek Mountains, at subsequent channel, lower part of resequent channel, and channels crossing the fault line. The relation between distance from the Taebaek Mountains and altitude is very obvious at the western side of the Taebaek Mountains. The values of altitude, height from riverbed, and stream order are highest at sedimentary rock and lowest at volcanic rock.
