Eight sweet sorghum varieties, 6 from United States and 2 from Japan, were introduced to select a higher yielding variety with high sugar content, high Brix percentage and better stem yield. Cultivation of these varieties was done at the field of Crop Experiment Station, O. R. D. in Suwon. From the data obtained in this study the following summary can be drawn. 1. All the varieties were observed to be highly adapable to the natural condition of Korea. Considering the trend in Brix percentage, 4% of Brix was measured at the stage of 70 days after seeding and there was a constant accumulation of sugar in plant, hereafter. The highest sugar content was observed on 40 days after heading but soon the sugar content kept decreasing. 2. At the early stage of 70 days after seeding, lower nodes showed higher sugar content than upper nodes but conversely at the medium stage, lower nodes from 1st to 4th one showed lower sugar content. Among these lower nodes, 2nd 3rd node was relatively lower than 1st node, and from the 4th node, there was an increase in sugar content with highest percentage at 6th, 7th and 8th node. Upper part above the 8th node indicated a decrease in the sugar contnet. 3. Correlation between Brix percentage and main quantitative characters were computed as follow; between the length of upper node and Brix, r=-0.981^*, which is significant negative correlation, and regression equation was Y=95,000-1,000X. Heading date vs Brix percentage r=0.738^*, Y=0.937Y-56,600, fresh stem weight, vs Brix percentage, r=0.737^*, Y=1.340X-316.110, sucrose content in stem vs Brix percentage, r=0.745^*, Y=1.095X-6.400. Thus, it is concluded that to select the plant with high Brix percentage and sugar content the relatively late maturing individuals with short internode in upper part and heavy fresh stem should be chosen. 4. Among the eight varieties tested, HC6028II-4, Rex orange and Ames amber were high in Birx percentage, crystalizable sucrose and purity percentage, and above varieties are considered to be sugar type. In the other hand, Tracy, Rurier Var-1, Red amber, Early sumac and Chinese amber showed high stem yield and relatively high Brix percentage but they are inferior in sugar content and purity percentage, which makes these varieties syrup type. Eight sweet sorghum varieties, 6 from United States and 2 from Japan, were introduced to select a higher yielding variety withhigh sugar content, high Brix percentage and better stem yield. It was observed that all the varietiesare highly adaptable to the natural condition of Korea. Accumulation of sugar in plant was begining at the stage of after heading, and the highest sugar content was observed 40 days after heading. The nodes of 6th, 7th and 8th showed the highest sugar content percentage and upper part above the 8th node showed a decrease inithe sugar content. Among eight varleties tested, the percentage of crystaizable sucrose in stem of HC6028II-4, Rex orange and Ames amber were 16. 84, 14. 14 and 11. 68, respectively and the percentage of the varieties was higher than those of other varieties. Correlations between Brix percentage and main quantitative characters were as follows: heading datevs Brix, r=0.738^*, fresh stem weight vs Brix, r=0.737^*, between the length of upper node and Brix, r=-0.981^*, sucrose content vs Brix, r=0.745.^*

Correct diagnosis of dementia syndromes is important to detect reversible dementias. In addition, accurate diagnosis enables the clinician to provide the patient and family with a more reliable prediction of the disease course. The clinical history should also establish the pattern of onset and the temporal course of symptoms. If dementia is identified, the cause of dementia must be investigated. This review has discussed the differential points of the dementia syndromes including Alzheimer disease, dementia with Lewy bodies, vascular dementia, frontotemporal dementia, progressive supranuclear palsy, corticobasal degeneration and prion disease.

1. For the development of stock farming in Korea, these things are to be remembered: the cultivation of imported forage crops was already tried out 50 or 60 years ago and, even if the result of cultivation was good, it did not mean the green signal for stock farming, because the stock farming can be developed only when, with the rise of the standard of living, the people demand great quantity of meat for their vital food. 2. Lespedeza, which is of korean origin, was exported to U.S.A. and cultivated widely as an important forage crops. In Korea, however, lespedeza can't be used economically as a forage crop, because difficulties in the establishment of grass land, as Korea is mountainous and lacks great plain and full of various weeds. 3. To see if pangola grass, which is very prolific and fast growing and one of the worst weed for cultivation of upland crops in Korea, but a favorite for livestocks, can be used forage crops, and its reaction against fertilizer, I fertilized the grass. The results: the grass. multiplies five times as compared to being unfertilized and reacts more favorable to three-element fertitizer than to one-element fertilizer. 4. When the seedlings of pangola grass are planted unfertilized, they lose their characteristic crawing habit and stnand upright, but, with enought nourishment, they regained the habit and the effect of the fertilizer on the grass is more remarkable than other crops.

The purpose of this study was to investigate the on-site problems that preschool teachers acknowledged related to their work places. The issues of this study began with not only the incidence, difficulty and solution of the problems perceived by preschool teachers but their level of the problems. The subjects were 151 teachers working at several preschools in the city located in Southeast of Korea, who answered the questionnaire. The results were as follows: First, regarding the incidence of the on-site problems, system was the highest problem in frequency, followed by 'time management', 'control and discipline of children', 'achievement and ability development of teachers', 'relationship with superintendent', 'facility/equipment', and 'program'. Second, regarding the difficulty level of the on-site problems, the problem of 'system' was the highest in difficulty level. Third, regarding the incidence and difficulty level of each problem', developing children's basic life' was the highest in frequency in the problem of 'control and discipline of children'. Then, regarding the difficulty level of each problem, in the problem of 'control and discipline of children', 'prevention and confrontation of children's safety accidents' was the highest in difficulty. Fourth, regarding the way of solution for the on-site problems, teachers chose to 'solve the problem with the advice of fellow teachers' for the problem of 'control and discipline of children'; for the problem of 'program'. For the problem of 'relationship with superintendent', they chose to 'try to understand, endure, and accept despite suffering'and for the problem of 'relationship with colleagues', they chose to 'try to understand, endure, and accept despite suffering'. Also, for the problem of 'relationship with parents', they chose to 'master and apply effective personal relation skills'. In addition, for the problem of 'facility/equipment', they chose to 'actively request the superintendent to repair or purchase needed facility/ equipment'.

I have researched the cultural inheritance of CHON JAE UY BAK KYU, and proposed to use his achievements practically. But there are a number of impractical contents in his works. Although there are no conspicuous characteristics in his achievements, they must be closely explored and examined. By examining his works, we can find a symbolic figure in the field of regional economy. For that purpose, we must give a great effort and wisdom to solve the problem made by misunderstanding or neglect. In this article, some of subjects related to the problem will be discussed.. At first, CHON JAE’s 3-dimensional attitude toward his period, country village, and involved persons is illuminated thoroughly. And the method for using his achievement in visual, cyber contents will be proposed. Finally his beneficial influence on his comtemporary will be discussed.

水稻早期移秧으로의 增收와 二化螟蟲 被害로 因한 收穫量差異에 關한 試驗

1. An experiment on earlier planting method of paddy has been carried out to determine its adaptability to the natural condition in the Seoul area, using five varieties of early maturing paddy. These seedlings were grown in the upland seedling beds covered with vinyl under which the lowest temperature in which paddy could be just germinated was maintained through out. Earlier planting method showed heavier infestation by rice stem borer and lower harvesting than both early and late planting methods. These results might be due to (firstly) low temperature which was unfavarable to growing seedlings, (secondly) the adult stage of rice stem borer which occured at the field, and (lastly) high temperature when it was at maturing stage, which caused insufficient maturing. However, although it is possible to have harvest in the beginning of September by earlier planting, this is not economically sound in the Seoul area, because the cost required for making upland planting, is prohibitive in the Seoul area, and because the cost required for making upland seedling beds covered with vinyl and the loss of harvest can not be compensated for by cultivating spinach and feeding crops such as radish, which can only grow in September after harvesting. 2. It is a well known phenomenon that the early planting method brings better harvest, effected by longer growing, But since it is more sound to avoid the loss of harvest caused by infestation than to increase harvest by longer growing period, the transplanting, in the Seoul area, was usually done in the middle of June in order to decrease the infestation of rice stem bore by keeping their adult stage in the seedling bed instead of paddy field. Recently, however, the control method of rice stem borer ha s well been established. Therefore another experiment was carried out on the early planting method, using control method. The paddies were sown in water seedling beds without using vinyl on 26th of April and these seedlings were transplanted on 5th of June. This result showed less infestation by rice stem borer than that of earlier planting method and heavier than that of late planting method. However, harvest was realized by this method. In considering only the foregoing results, it may be possible to adopt this method in Korea, provided that rice stem borer should be controlled with insecticide. But early planting method could be adopted only to the limited area where paddy fields had permanent water supply, which covered one half of the total paddy fields. Because every three year the rainfall comes so late that in the paddy field, where the water supply relies on the rainfalls it is impossible to transplant seedlings before late in June and, on the other hand, it is necessary to control the rice stem borer, since the results obtained on the infestation showed a heavier loss, 3,635 suk, by an uncontrolled test compared with 5,219 suk by a controlled test, and in controlling them no success could be expected with only partial control. 3. In Korea, the paddy fields where water supply relies on the rainfall were often in shortage of water for transplanting before the middle of June because of drought, so that it is not avoidable to use the tempoerary planting method of seedling and the old seedling for the late transplanting. For the purpose of avoiding these defects an experiment was done on the late planting method. These results showed that the degree of infestation by rice stem borer on both the controlled and the uncontrolled test were 0.08 and 0.48, which was negligible when the control method was applied. In comparing the degree of infestation it was quite less than both early and earlier planting methods. In the harvest it was 5,162 suk which was slightly less than 5,292 suk obtained by the early planting method. One important thing in this experiment was that there are slight differences in harvest between the uncontrolled test of late planting method and the controlled test of earlier planting method. Therefore, it may be concluded that for the paddy field without watersupply the late planting method could well be adopted, and in the southern part of Korea where precultivating before transplanting is possible, the late planting method could be also adopted, provided the precultivating with crops such as poraroes and flax for which sufficient period for the maturing should be given and cultivating crops after harvest are ensured.

This experiment was carried out to study the changing of soil physical-chemical proper ties and a good green manure crop in order to make the mature field for shortage period. The results obtained were summarized as follows; 1. In case of barnyard millet plot physical properties of soil was improved compare to control, including the bulk density and hardness. 2. Changing of soil chemical properties did not show certain tendency, but the only orgarnic matter's quantity was high in case of no lime treatment. 3. In case of lime treatment, fresh weight of lettuce was high. There was highly significant positive correlation between Root weight and Yields of lettuce. 4. the yield of green manure was highest in case of barnyard millet treatment. Barnyard millet seemed to be the best for green manure in newly reclaimed field.
