This experiment was carried out to elucidate the effect of the midsummer drainage times and some growth regulators on lodging characters, lodging and yield in puddled-soil drill seeding in rice. Dongjinbyeo, the mid-late maturing rice variety was seeded at May 11 by seeding machine with 4cm of furrow depth. Experimental plots were divided two main treatment without midsummer drain and two time drains (30 and 50 days after seeding), Inabenfide(IBF) was applied 40days before heading(DBH) and IBP was applied at 30DBH, respectively. Culm length was shorten, the wall of N$_4$ was thicken, and the breaking weight was increased at two time drainage and growth regulators applied in order of Inabenfide, IBP, and Control. Lodging wasn't occurred at two time drainage but it was occurred at none drainage in the order of Control, IBP, and Inabenfide applied. Yield was higher at two time drainage compared with none drainage and higher in order of Inabenfide, IBP and Control in none drainage but wasn't significantly different among growth regulators applied in two time drainage. Therefore, two times midsummer soil drying is recommendable management method for puddled -soil drill seeding of rice.

The growth, size and morphology of leaves, which foliated on the same shoot and time in the early growth season, were studied in 12 woody species in temperate deciduous forests of Korea, and the equation for the index of heteromorphism of leaves was fonnulated. The numbers of leaves per shoot were from 3 to 7 in early growth season and the numbers of synchronous leafing were from 2 to 6. All the leaves on a shoot were reached maximum values of specific leaf arells at the SIlme time nearly. The differences of the length (L) and breadth (B) of leaves along leaf rank (plastochron) were conspicuous, except for Quercus variabilis. Especially, in 10 species, the ~fferences of the neighbouring leaves were significant at 0.001 or 0.05 level. The index of leaf heteromorphism was calculated from the data based on $L\;{\times}\;B$ and LIB, and similar to differences of actual leaves along leaf rank. The values of index of heteromorphism were high in Carpinus tschonosldi, Styrax obassia, Ulmus davidiana, Rhamnus yoshinoi and Symplocos chinensis for. pilosa, and low in Sorbus alnifolia and Tilia amurensis. The index of heteromorphism had no relation to other characters of the leaf or life fonn of the species. It was thought that the differences along leaf rank were related to the degree of adaptation to environment, especially to changing air temperature in early growth season.season.

The growth characteristics, forage yields and nutritive values of heading and headless types of sorghum $\times$ sudangrass(Sorghum bicolar L.) hybrids were examined to evaluate the adaptability of new cultivars at Suwon and Chunahn for two years from 2000 to 2001 in a randomized complete block design with three replications. Eleven cultivars of heading type and 4 cultivars of headless type were used in this study. The dry matter(DM) yield of AG 2501 was highest in the heading type cultivars, and PAC F8350 in the headless type cultivars, respectively. The DM yields of heading types were slightly higher than those of headless types but there were not significantly different. Early growth and regrowth characteristics of heading type was highest in AG 2501 and GW 9110G, respectively. GW 9110G and DMD were early heading types, and AG 2501 and GW 9161F were middle heading types. AG 2501 was longest and GW 9161F was shortest in plant height. Cultivars with long leaf length were appeared to be larger fur leaf width and stem diameter. Brix content was highest in DMD as 9.7%, and disease and insect resistances were not significantly different among the heading types. Early growth of headless type cultivar, PAC F8350 was slightly lower than that of Jumbo but stronger in regrowth, wider in leaf width and stem diameter, and stronger in lodging. Comparisons of growth characters between heading and headless types of cultivars were not easy in general but between them, brix contents of heading types ranging from 6.7 to 7.9% were greatly higher than those of headless types ranging from 3.6 to 3.9%. Nutritive values such as crude protein, ADF, NDF and digestibility of headless type cultivars were higher than those of heading types. In conclusion, of heading type cultivars, GW 9110G, AG 2501, DMD and GW 9161F, and of headless type cultivars, Jumbo and PAC F8350 were recommended as high yielding cultivars with good adaptability in domestic environment.

To select the superior clones of Populus alba ${\times}$ Populus glandulosa $F_1$, growth and some growth-related physiological characters were examined for thirteen, one-year-old and fifteen, two-year-old clones, respectively at the Seoul National University nursery in Suweon, Clonal differences in growth (total dry weight per tree), leaf area per tree and leaf chlorophyll content per tree at tow-year-old plots were highly significant at the 1% level, but not at one-year-old plots, Highly significant correlation was found between leaf area per tree and total dry weigh per tree (r=0.865), between leaf chlorophyll content per tree and total dry weight per tree (r=0.888), and between photosynthetic ability per tree and total dry weight per tree (r=0.745). The photosynthetic ability and leaf chlorophyll content per unit leaf area of one-year-old plant increased with increasing leaf order number from top. reached maximum value in the twenty-eithth and thirty-third leaves, respectively, and then decreased gradually from those leaved to base, Clones 68-1-54, 66-26-55 and 65-22-11 showed test growth based on leaf area per tree, leaf chlorophyll content per unit leaf area and photosynthetic ability of leaf tissue per unit area. Growth yield of populus alba ${\times}$ P. glandulosa $F_1$ clones could be estimated from either leaf area per tree of leaf chlorophyll content per tree. Therefore, measurements of leaf area and leaf chlorophyll content appear useful to select superior populus clones early growth.

The experiment was carried out to make clear the root characters and relationships among some quantitative characters of soybeans. The results obtained are summarized as follows: 1. Stem diameter was shown the greater growing in thickness after one month from sowing than the earlier stage, and the greater growing was shown in fertile bed soil than in sand soil. 2. The elongation of plant top in soybean plant was also shown the greater rate in bed soil than in sand soil 3. The length of plant root was longer than the length of plant top in the earlier stage of growing, and the length of root was much greater in sand soil than in fertile bed soil. 4. Weight of plant top was shown more in bed soil than in sand soil, but this tendency was shown more greater rate in the length of plant top than in weight of plant top. 5. Weight of root was more compared with weight of plant top in the earlier stage of growth, and also more greater rate was shown in sand soil than in fertile bed soil. 6. Highly significant correlations were shown among five quantitative characters, namely stem diameter, length of top, weight of top, length of root and weight of root, etc.

The Pancreatic islet are the clusters of endocrine cells scattered through out the exocrine pancreas. Transplantation of a sufficient pancreatic islets can normalize blood glucose level so that may prevent devastating complications of type I diabetes(IDDM) and other side effects of the IDDM. Recently, there are several approaches to transplant sufficient pancreatic islet, and it was comprised in increase or regeneration of the endogenous $\beta$-cell mass from donor's pancreas, but relatively few studies have been devoted to the morphological characters of the isolated and 3 day cultured pancreatic islets. We investigated morphological pattern of intracellular structure of isolated and 3 day cultured pancreatic islets. The morphological characters of the pancreatic islets were observed by scanning electron microscope and transmission electron microscope, and insulin distribution of the each islets were observed by transmission electron microscope, and were labeled with insulin antibody. Intracellular structures including nuclei, mitochondria, RER, Golgi complex and many secretory granules were normally appeared in the isolated pancreatic islets which was extracted immediately dornor's pancreas, however, There is a significant morphological changes between the 3 day cultured pancreatic islets and isolated islets. 3 day cultured pancreatic islet's $\beta$-cells had normal nuclei but increased cytoplasm mass and RER and developed Golgi complex. Insulin secretory granules were decreased in numbers rather than isolated pancreatic islet. In this study, the pattern of intracellular structure variation was examined during pancreatic islet culture. Most distinct features are variation of the insulin secretory granules, and developed RER, and dilated golgi complex. Therefore, we suggested that the various change of the morphological characters on cultured pancreatic islets were responsible for the function(biosynthesis and secretion of insulin) and growth. These results were also cultured islets have greater ability to recover and maintain normoglycemia than isolated islet transplantation.

This study aims to study the relationship and narrative structure through types of conscious shown through characters of animation. Regardless of professional knowledge, animation viewers are able to decide sympathy cognitively during watching. There are previous studies examining elements regarding the sympathy felt by viewers, "how much sympathy one feels about the story" conveyed by character is one of the most significant element. "Sympathizing" is reacting to the emotion of character, which does not concentrate on visual phenomenon revealing from appearance and mise en scene, but from "conscious" establishing relationship from behavior and practice. In other words, it starts from in-depth insight regarding the types of conscious and relationship between characters. Therefore, this thesis aims to analyze the types of conscious of main character Simon of Japanese animation which was aired in Korea in 27 episodes, and analyze how it conducted meaning structuralization of relationship with surrounding characters in the growth process of every episode. When analyzing the animation, the study concentrated on analyzing the conscious formation process of character, completeness of relationship and structure rather than the plot or power of delivery of direction, to insist that animation should not only convey humor or fun but secure the in-dept self discernment.

The correlation and combining abilities related with plant spreading characteristics of plant height, plant width, stem length, internode length, number of stem, number of leaves, and number of flower were studied in the $F_1s$ of 10 crosses from the partial five-parent diallel cross in Petunia hybrida. The plant width showed highly positive correlation with internode length, and number of flower. The mean squares of general combining ability(GCA) and specific combining ability(SCA) were highly significant for plant width, number of stem, number of leaves, and number of flowers. The mean square values of GCA were greater than those of SCA for all the characters, showing preponderance of additive gene actions for these characters. The lines of D and I for plant width and length of stem showed relatively high GCA effects. The crosses of $D{\times}I$, $F{\times}I$, and $G{\times}I$ exhibited high SCA effects on plant width, especially $G{\times}I$ effected in internode length and number of flower. The broad sense heritability was generally high compared to narrow sense one. Plant width and stem length, and internode length related to spreading growth showed the higher heritability than the other characters in the broad and narrow sense.

GL(Girls' Love), which deals with romance between women, is considered a small, minor culture in the sub-culture market. Nevertheless, recent 'reboot feminism' in the voice of women in the epic that appears to be the central protagonist is increased, and interest in naturally glIncreasing. It encourages those who declare "post BL" to consume GLs featuring female characters instead of male characters. In an atmosphere where female creators consume female dictionaries who write women's stories and argue that they should expand the scope of their female counterparts, "Her Simcheong," a webtoon that won the 2018 Our Comics Award, explores the possibility of female epic through rewriting myths. Gender norms given to women, such as filial piety and nirvana, all get new names in . A good daughter is a liar, and a good wife has a woman she loves. Besides Simcheong, hit-and-run mothers, Jang Seung-sang's wife and Jang Seung-sang's daughter-in-law also focus on female characters' stories, highlighting solidarity among women to survive in a male-dominated society. In this process, solidarity among women naturally leads to GL imagination. Her Simcheong describes direct sexual contact, such as kissing and hugging among women, as beautiful illustrations, and shows romance between women in a manless world. While solidarity among women is always regarded as 'undangerous' friendship or girlish sensibility, the romance between women in breaks the cultural rules of women's growth novel and women's trade. This reveals the inconsistency of the conspiratorial male solidarity, which has been trading women around hegemony.

Selection of oat variety according to cultivation period is an important to increase productivity of forage crop. To investigate the growth characters and dry matter productivity of oats according to cultivation period, early-maturing oat(EM0) and medium-maturing oat(MM0) variety were sown in spring and autumn at central district of Korea. When oats were cultivated in spring, MMO variety was longer 8 cm in leaf length and wider 5 mm in leaf width than 25 cm and 12 mm of EM0 variety, rexpectively. but in autumn, those were not different between maturities of oat varieties. Plant length of MMO variety was longer 7 cm than that of EM0 Variety in spring cultivation, but in autumn, plant length of EM0 variety was longer 14 cm than that of MMO variety. Heading dates were 20th to 22th May in EM0 variety, and 30th May to 10th June in MMO variety in spring cultivation, and ear of EM0 variety emerged 30th Oct. to loth Nov. but that of MMO variety did not emerge at harvesting day in autumn cultivation. In Spring cultivation, dry matter(DM) yield of EM0 variety was 7,349 kg/ha that was less 56% than 11,466 kg/ha of MMO variety, but In Autumn, was more 15% than 6,575 kg/ha of MMO variety. In conclusion, selection of oat variety in spring and autumn cultivation can be different with cropping system of forage crop, and this trial is suggesting that oat variety could be sown MMO variety in spring and EM0 variety in autumn at central district of Korea.
