To develop good soybean varieties for sprouts. 285 indigenous lines and 16 recommending varieties were evaluated by the sprout and agronomic characteristics. The range of whole length, hypocotyl length, root length, and yield rate of sprouts was 9.5~23.0cm, 5.9~15.1cm, 3.2~9.2cm, and 121~695%, respectively. Yield rate of sprouts was the highest, 409%, in the lines of mixed seed coat color. At the same time, it was reversely proportional to seed weight : the smaller the seed weight, the higher the yield rate as in all other reports. The number of roots was significantly fewer in the lines of the black and the green seed coat color than others. Based on whole length, rate of root length, and yield rate of sprouts, many indigenous lines were evaluated much better than recommending varieties. In the hypocotyl color of sprouts, the brightness was higher in improved variety than indigenous lines but vice versa in redness and yellowness in general.

The thyroid gland is an endocrine organ which is mainly derived from endodermal cell of the primitive pharynx. It is well known that time of morphological and functional maturation of thyroid gland is so variable among the species of animal that functionl maturation of thyroid gland of the rat occurs only after birth of the animal, while the human fetal thyroid gland can secrete thyroid hormones at 10-14 weeks of gestation. In this study the author pursued the ultrastructural differentiation of thyroid follicular cells of rats in the late fetal and early postnatal lives. The fetal rats of 18th and the 20th day of gestation and rats of the 1st, the 7th, the 14th and the 21st day of postnatal life were sacrificed and thyroid glands were extracted. Rats of the 8th weeks of postnatal life were served as control group. All specimens prefixed in 2% glutaraldehyde-2.5% paraformaldehyde and postfixed in osmium tetraoxide, were dehydrated and embeded in Epon Araldite 502. Ultrathin section about 600-800 in thickness were made with LKB ultramicrotome and stained with uranyl acetate and lead citrate and lead citrate All electron microscopic preparations were observed with JEM 100cx-II electron microscope The result obtained were as follows: 1. The nucleus of the follicular cell in the rat thyroid gland was composed of euchromatin at the 18th day of gestation, some unclei with euchromatin and heterochromatin were observed at the 20th day of gestation, and all nuclei of the follicular cells were composed of euchromatin and heterochromatin after the 1st day of postnatal life. 2. Rough endoplasmic reticulum of the follicular cell in the rat thyroid gland was consisted of column shaped scant cisternae at the 18th day of gestation, and rough endoplasmic reticulum with unmerous dilated cisterne was observed at the 7th day of gestation. 3. The Golgi complex of the follicular cell in the rat thyroid gland was composed of narrow cisternae and small sized vesicles at the 18th day of gestation. Folgi complex with wide cisternae and large sized vesicles and vacuoles was observed at the 14th day of posnatal life. 4. Mitochondria of the follicular cell in the rat thyroid gland were scanty at the 18th day of gestation and number of mitochondria increased during development of thyroid gland. 5. Lysosmes of the follicular cell in the rat thyroid gland were observed from the 1st day of postnatal life. 6. Collid lumen and microvilli of the thyroid follicle were observed from the 20th day of gestation and the matured colloid lumen was observed at the 1st day of postnated life. It is consequently suggested that the thyroid follicleis are formed from the 20th day of gestation to the 1st day of postnatal life, and cytoplasmic organelles of the folliculat cell are matured morphologically between the 7th and the 14th day of postnatal life in albino rats.

The objective of the current study consists in inquiring into how Korean traditional dance and ballet majors are interested in their weight control and what preference they have for ingestion, to articulately elucidate physical management for weight control and dietary habits in those college students who major in dance. Analysis of differences between the two groups revealed findings, as follows; 1. Both the Korean traditional dance majors group and ballet majors group take the time of physical weight control fifteen days ahead of the date of their exhibition or performance, by 64.5%. The Korean traditional dance group show the period of the most interest in weight control while studying in senior high school by 61.0%, whereas the ballet major group by 51.0%. Concurrently with this they were most affected by school lessons by 45.0% or mass communication by 30.0%, and it was carried out by their own judgment by 76.5%. The number of students who think they are 'fat' wish a loss of weight by 55.0% in the Korean traditional dance majors group, and by 43.0% in the ballet majors group. For the techiques of physical weight reduction, the employ 'reduction of the quantity of food intake' by 54.5%, and 'an increase of the quantity of motion' by 20.0%, which indicates that diet and exercise are considered the most effective method. 2. They generally prefer two meals a day, one meal less than the normal number of meals, three time. The lenth of mealtime reveals '10 to 20 minute', by 64.0% in Korean traditional dance group, and by '20 to 30' by 60.0% in the ballet majors gorup, which indicates a longer time in the former group than in the latter. Almost all the dance majors eat snacks by 98.5%, and the reason for that gives the highest responses in 'habitually' by 37.0%. Most of dance majors represent irregularity in taking meals, and the reason for going without a meal is ascribed to 'no time to eat' or 'weight control'. Furthermore, mooted points on dietary habits are most reflected from 'irregular mealtime' by 39.0%, and 'the ingestion of finished food and instant food' by 30.5%. From these, they are well aware of the need to improve. 3. The highest preference for food is put on the generalized food, whereas food on a low level of recognition gives a low level of preference for that food. In general, fruit gives a high preference, for the foods that dance majors abhor include animal liver, bacon, dried slices of seasoned white bait, margarine, soybean milk, jam, etc. But a great preference is shown from yofle(yogurt) by forming 83.0%.

It needs a large capacity of equipments to test the starting performance of middle and large synchronous motors in a factory. This paper propose a new method which is the combination of single phase AC applied test and usual routine test with a small synchronous test machine and testing equipments. We can obtain the results from these proposed tests as follows ; (1) The starting performance and stabilized operation at variable speed is predicted from this results. (2) The armature winding leakage reactance is resulted from the no-load saturation curve, the short-circuit charactristic curve and the armature-reaction magnetomotive force converted to the field current. (3) This test must be performed twice, one for short-circuiting the field winding, the other for joining a resistance between the field terminals, as a result the unknown constants in equivalent circuits are identified. (4) Inverter-fed three phase voltage with variable frequency is applied to armature terminals, as a result, We show the actual armature leakage reactance and reaction of the induced harmonic voltages from rotor.

박신영,이동균,황호길 大韓齒科保存學會 2012 Restorative Dentistry & Endodontics Vol.37 No.2

Objectives: The purpose of this study was to assess the accuracy of Root ZX (J. Morita Corp.) according to the location of major foramen and open apex. Materials and Methods: 81 mandibular premolars with mature apices were selected. After access preparation, 27 teeth were instrumented to simulate open apices. 54 teeth were classified according to location of major foramen under surgical microscope (x16). The file was fixed at the location of apical constriction by Root ZX using glass ionomer cement. The apical 4 mm of the apex was exposed and photo was taken and the distance from file tip to the major foramen was measured by calibrating metal ruler on graph paper. The results were statistically analyzed using ANOVA and Scheffe test at p < 0.05 level. Results: mean distance from file tip to major foramen was 0.308 mm in Tip foramen group (Ⅰ), 0.519 mm in Lateral foramen group (Ⅱ) and 0.932 mm in open apex group (Ⅲ). Root ZX located apical constriction accurately within ± 0.5 mm in group Ⅰ of 85.71%, in group Ⅱ of 59.09%, and in group Ⅲ of 33.33%. There was a statistically significant difference between group Ⅰ and Ⅲ (p < 0.05). Conclusion: Root ZX located apical constriction accurately regardless of location of major foramen. However, Root ZX couldn't find it in open apex. Clinicians have to use a combination of methods to determine an appropriate working length at open apex. It may be more successful than relying on just electronic apes locator. (Restor Dent Endoe 2012;37(2):68-73)
