  • Anthers of three cross combinations of hot-pepper(Capsicum annuum L.) were cultured on Dumas De Vaulx medium supplemented with some growth regulators. The embryo production efficiency and the diversity for agronomic traits in $A_2$ lines were investigated. The embryo production frequencies of hybrid combinations were ranged from 16.4% to 43.4%, the highest embryo induction combination was DGSH $\times$ C-NH with 43.4% embryogenic efficiency. Among total 275 $A_2$ lines, phenotypic variants were found in six lines, 2.1% variant frequency. The diversity of $A_2$ lines derived from anther culture was different according to the cross combinations. Fruit color was within parental range, no transgressive variation was observed. However leaf color showed transgressive variation. In fruit length, fruit width and fruit weight, one C-HC $\times$ DGSH and DGSH $\times$ C-NH showed great diversity compared with doner parents while Cheokjo 1 $\times$ C-NH crossed with Cheokjo 1 with big fruit shape showed small diversity. Stem length to 1st branch was relatively similer to or longer than donor parents. Stem thick exhibited remarkable diversity. Node number to 1st branch distributed alomost within the range of donor parents in C-HC $\times$ DGSH combination, however great transgressive variations were observed in DGSH $\times$ C-NH and Cheokjo 1 $\times$ C-NH combinations.

  • Colors in the film can communicate with the audiences without a dialogue as deep as possible, and then colors make a audiences sympathy as a role playing like a main character. The movie that I chosen by this thesis is The mother(UK film, 2003). This movie is so powerful imagetelling movie I've ever seen in the meaning of tool as a character-narrative film. This imagetelling in the movie is so useful and powerful, and then image is more important than any other things in the movie as a narrative tool and storytelling.

  • Regim-8(TIBA), a Chemical pinching agent, was applied to soybean plants of 6 varieties at 6 leaf stage in oder to develop a chemical pruning method. The results are summarized as follows: 1) The more inhibition in plant height and rare lodging were abserved at 2, 000ppm level of treatment (50cc of Regim-8 diluted in 100ι of water). 2) Number of branches and grains per plant were increased by Regim-8 treatment, while number of main stem nodes were decreased. 3) It appeared that photosynthetic efficiency of the soybean plant community treated by Regin-8 were improved. This increased number of pod per plant and hence soybean yield increased by applying Regim-8. 4) Antilodging effects of Regim-8 were also appeared to result in better filling of pods and higher yield per unit area.

  • In metropolitan area, intersections having turn Prohibitions are often found and it is important to consider them in path planning. This Paper presents a new path planning method road networks having turn prohibitions. A new road network model is proposed in which an alter-native route for each turn-Prohibition is constructed in off-line using U-turn or P-turn and then Put into road network database. The proposed network model is efficient since it requires no virtual nodes that are usually used in the conventional road networks to represent turns at intersections. In order to find a shortest path with the proposed network, a new shortest path algorithm is proposed. A knot for the turn-Prohibited node is newly defined and is used in comparing the cost of the alternative route with that of the other path.

  • This experiment was carried out to analyze the effects of substrate reuse on the growth and yield of summer paprika in cyclic hydroponics. The test group was divided into a new coco slab, one year reused coco slab two year reused coco slab based on 30% nutrient solution reuse, and was performed from April 18 to November 31, 2016 for 30 weeks. As a result, plant height of early growth was that the 2 year reused slab was longer than the new slab but the final growth period was 56.58 cm shorter. First group flower position was that reused slab was shorter by 2.92 cm than the new slab and the second group flower position was 0.31 cm long. The relative internode length of early growth, when the reused slab was used, the imbalance in the late growth stage was increased compared with the use of the new slab. The number of growth nodes in the 1 and 2 year reused slab was the smallest with 27.4 nodes. However, the number of harvested nodes did not show the difference in the test group, and the ratio of harvested that the 2 year reused slab was the highest at 26.8%. The ratio of unmarketable fruit tended to increase as the growth progressed. Fresh weight was 227.7g for new slab, 219.2g for 2 year reused slab and 21.2g for 1 year reused slab. The dry weight of the new slab increased with the reuse of the slab. It was 17.13g for new slab, 18.26g for 1 year reused, and 19.28g for 2 year reused. The average water content of the entire growth period was smaller as the slab was reused, and the 1 year reused slab was about 20g less than the 2 year reused slab. This trend was steadily occurring throughout the entire growing season. Especially, the reused slab for 1 year was less than 60g after 3 groups compared to other test groups. In conclusion, If will control seriously occurrence of unmarketable fruits by weakening after medium growth in summer-cultivated paprika in EC-based recycling hydroponic cultivation with reused cocopeat substrate, It is not what I have to worry that decrease of the yield and deterioration of the quality due to the change of physical and chemical properties of the slab and the pathogenic bacteria infection.

  • The ant fauna in Mt. Gariwangsan was composed of 39 species 24 genera 5 subfamilies. The collected ants in Mt. Gariwangsan were Subfamily Myrmicinae(16 species 11 genera), Subfamily Formicinae(15 species 5 genera), Subfamily Ponerinae(6 species 4 genera), Subfamily Amblyoponinae(1 species 1 genera), and Subfamily Dolichoderrinae(1 species 1 genera). Ant fauna by vegetation in Mt. Gariwangsan, 36 species 23 genera were collected in broadleaf tree areas in which Quercus mongolica, Fraxinus rhynchophylla, Tilia amurensis, and Cornus controversa were dominant species. Paratrechina flavipes and Myrmica kotokui were dominant species. 13 species 12 genera were collected only in broadleaf tree areas. In the coniferous tree areas where Pinus densiflora, Pinus korainensis, and Larix kaempferi were dominant, 24 species 15 genera of ants in total were collected. Pachycondyla chinensis and Paratrechina flavipes were dominant species. 4 species 3 genera were collected only in the coniferous tree areas. Paratrechina flavipes was dominant even in the areas in which Camponotus japonicas and Formica japonica had been assumed to be dominant. Specifically, the higher the land was, the rarer Ponerinae and Dolichoderinae were observed. The common species observed in both areas were 20 species 13 genera. Of these ants, Paratrechina flavipes(Subfamily Formicinae) and Myrmica kotokui(Subfamily Myrmicinae) were distinctive ants. With regard to the current state of colony of these species, Paratrechina flavipes was dominant in lowland areas. Myrmica kotokui, on the other hand, was dominant in highland areas.

  • Multiple shoots obtained in MS medium suppler with 5.0 mg/L BA though shoot-tip culture. The frequency of vitrified shoot was lower on Bacto-agar medium than on Gelrite as gelling agent. Addition of activated charcoal at concentrations of 0.1~0.3% reduced vitrification and markedly increased shoot growth, and formation and growth of roots, but significantly reduced the number of shoots formed. The ratio of fresh weight to dry weight was decreased by increasing light intensity and agar concentration. Eight-tenths times of macroelement of MS medium was observed to be effective for shoot formation. Addition of IAA effectively promoted shoot formation in both shoot tip and node-bud explants. Supplement of 5.0 mg/L BA, 0.3 mg/L IAA to MS medium was most effective in shoot proliferation on shoot tip and node-bud explants.Multiple shoots obtained in MS medium suppler with 5.0 mg/L BA though shoot-tip culture.

  • RAPD test and the observation of morphological, cultural characteristics of fourteen selected entomogenous fungi were conducted to investigate the analysis of their internal relationships. Paecilomyces tenuipes showed snow flower form attached to numerous white conidiophores, produced globular and semi-egg types on the club types of phialides. Cordyceps militaris formed globosely conidiophores, dark yellow fruiting body on pupa. The phialide as on Acremonium-type in global conidiophores. Beauveria bassiana covered with conidia was not formed fruiting body and adhered conidia on conidiophore of zigzag type. The PDA and SDAY medium were confirmed as an optimum growth of them. P. tenuipes showed to velvet and plane types in several media whereas C. militaris was belong to centrally raised and floccose in the morphological type. In contrast, B. bassiana covered with conidia on velvet shape. The size of amplified products were analyzed by RAPD using URP primer and were from 100 bp to 2.0 kb with $10{\sim}14$ geuomic DNA. Total similarities of two groups were by dendrogram of UPGMA analysis. The homology of P. tenuipes groups was 94.8 to 100%. It also showed 70.1 to 96.6% in C. militaris group and B. bassiana was higher similarity than any other. The internal change of C. militaris, produced telemorph fruiting body, was higher seperated in species than P. tenuipes and B. bassiana in the RAPD.

  • Herbicides were classified by two-dimensional ordination analysis based on the weed flora which was not controlled by application of a particular herbicide. The number of herbicide group was varied depending upon the weed community type and the experiment site. The technique of the two-dimensional ordination analysis gave more comprehensive informations about selecting of herbicides for increasing the herbicidal efficacy, for increasing the weed spectrum and for reducing the herbicide cost by mixing of herbicides. The two-dimensional ordination analysis could be used not only herbicide classification and selecting effective herbicide or herbicide combination but also can be used for the evaluation of systematic application of herbicides.
