C의 含量은 短果枝가 많았고 N의 含量은 長果枝가 많았으며, C/N율은 短果枝가 높았다. 長果枝는 果實이 크고 果形指數가 높았으며 短果枝는 硬度가 높았다. 果實 部位別 硬度는 頂部가 側部보다 높았다. Effects of tree vigor of 'Fuyu' persimmon on growth of branch, fruit enlargement growth and sun scald injury were examined, and the results obtained are as follows. The stronger tree vigor was, the higher tree height was and the weaker tree vigor was, the longer tree spread than tree height was. Number of fruit, leaf and number of leaf per a fruit were increased with strong tree vigor. Ratio of sun scald injury fruit was decreased with strong tree vigor and increased with weak tree vigor. In direction, ratio of sun scald injury fruit was south, west, east and north in order and north was low without relation of tree vigor. In elongation of shoot, both long fruiting branch and short fruiting branch are slight and leaf number seemed to decrease. Nevertheless, diameter of shoot increased continually. The content of C was high in shorting fruiting branch, the content of N was high in long fruiting branch and in C/N ratio, short fruiting·branch, was high. Fruit transverse was long and shape index of fruit was high in long fruiting branch and fruit firmness was high in short fruiting branch. In fruit firmness at parts, apex part was higher than side part.

Background : This study was carried out to investigate the differences of growth characteristics, photosynthetic rate and ginsenoside content of Panax ginseng C. A. Meyer according to the covering materials during house cultivation. Also the results of this study will be used as basic data for the standardization of ginseng house cultivation. Methods and Results : This experiment site was conducted from March to October, 2017 in the house located in Jinan - gun, Jeollabuk-do. The ginseng cultivar used in the experiment was a violet stem variant of 4-years-old. There are three kinds of covering materials used in the experiments: polyethylene (PE) film, scattering film, and blue-white film. PE film and the scattering film were first coated with 85% of light shielding net after the first installation, and then secondly coated with 75% and 30% of the light shielding net respectively in the middle of May when the house temperature reached 25℃. The blue-white film was cultivated after the initial installation without further treatment. The light transmittance of each covering materials were in the order of scattering film (14.5 ± 1.5%), blue-white film (10.0 ± 1.0%) and PE film (6.7 ± 1.0%). The average photosynthetic rate of each treatment was in the order of scattering film (2.94 μmol CO2/㎡/s), blue film (2.71 μmol CO2/㎡/s) and PE film (2.34 μmol CO2/㎡/s). Aboveground growth characteristics of ginseng were good in a scattering film and blue-white film. Root weights were found in the order of scattering film (47.1 g/plant) > blue-green film (41.3 g/plant) > PE film (37.6 g/plant). Conclusion : In order to select proper covering materials for ginseng house cultivation, the growth and photosynthetic characteristics of each treatment were compared with each other in order of scattering film, blue-white film and PE film. The photosynthetic rate of each treatment was measured according to the growing season. PE film was relatively low during the entire growth period. In the case of scattering film and blue-white film, the rate of photosynthesis was higher in the scattering film with high light transmittance until May, but showed a similar tendency after July. As a result, the difference in the growth characteristics of ginseng is thought to be due to differences in photosynthesis and assimilation according to the coating materials.

Specimens of 89 cases of pterygia in adult patients were thoroughly examined with light and electron-microscope. In addition to H & E staining, PAS, Masson trichrome, Goldswithch's and Verhoeff's special stainings were conducted. Interpretation of histopathological findings on the abnormal tissues in relation to the patients age groups ad the duration of disease course enabled to conclude as follows: 1. Histopathological alterations in the pterygia were encountered throughout the tissues of the conjunctival epithelium, immediate subepithelial layer and deep layer of substantia propria as well. 2. The concept of "senile elastosis" as the compatible term of the specific finding of pterygium was deniable since the process of tissue alteration in patient did not concurrently progress with aging. 3. Relatively early occurrence of elastodysplasia in deep layer of substantia propria lead to indicate the possibility of primary lesion in combination of activity of fibrocytes in vicinity induced by various factors including the hereditary disposition. 3. Histopathological changes in epithelial and subepithelial hyalinization appeared to be secondary alterations.

Experiments on the 1eaf characteristics have been carried out in sweet persimmon cultivars. The results obtained are as followings : Mikado and Daean-Dangam were the largest for leaf length, leaf width, leaf area and leaf weight in all cultivars, while Suido was the smallest for leaf width, leaf area and leaf weight. Suruga was the thickest for the leaf thickness, but Johongsi was the thinnest. The largest leaf stalk diameter was observed in Mikado and Ichimogkei-Jiro, but the smallest was Hana-Gosho. For the leaf stalk length, Kyara was the longest and Zenjimaru the shortest. For the index of leaf shape, RO-19 showed the largest as 66.5% for the south-facing leaf and 68.3% for the north-facing leaf, but Kyara and Suido showed smallest. The south-facing leaf showed large values in lcaf shape index, leaf thickness, leaf stalk diameter and leaf stalk length, but the north-facing leaf was relatively large in leaf length, leaf width, leaf area and leaf weight. For the content of chlorophyll, Hana-Gosho and RO-19 cultivars contained higher, but Yido and Bang-Gosho contained lower. In average for all cultivars, the contents of N, Ca and B were low, that of P seemed in sufficient and those of K and Mg were difficient. However, the contents of Na, Cu, Zn, Fe and Mn were moderate. The content of Al in particular, were high(81-148ppm) for all cultivars.

PURPOSES: This study suggests the application of glow line marking technology for reducing traffic accidents at nighttime. METHODS: In this study, using a statistical analysis, we analyzed the characteristics of traffic accidents occurring at nighttime. Next, the strength, weakness, opportunity, and threat (SWOT) factors were derived based on a current-status analysis of glow line marking technology and road environments. An SO strategy, ST strategy, WO strategy, and WT strategy were established in accordance with the four SWOT factors. RESULTS : This study suggests that the following strategies should be promoted to apply glow line marking technology to a road environment: 1) an activation strategy for the technological development of glow line markings for a new paradigm in reducing traffic accidents, 2) a benefit enhancement strategy applying glow line marking technology in places where nighttime traffic accidents frequently occur, 3) a strategy for the expansion of glow line marking by replacing streetlights, and 4) a strategy for enhancing road applications through the development of various line marking methods in consideration of both performance and costs. CONCLUSIONS : The application of glow line markings in a road environment can contribute to a reduction of traffic accidents at nighttime, and aid energy savings from the replacement of streetlights.

生長調節制 處理, 低溫貯臟 및 出庫后의 條件이 단감 品質變化에 미치는 影響

李容門 건국대학교 1987 論文集 Vol.24 No.1

This experiment was carried out to investigate change of vitamin C and composition of fatty acids in persimmon fruits by treatment of various growth regulators and effect of the low-temperature storage of the fruits bagged in polyethylene-film on the fruit quality. The results obtained were as followers; 1. In general, the in sloe temperature of the bags showed a slight decrease within one day after the fruit transfer from the storage temperature to the room temperature. Two days later after the transfer, the temperature increased rapidly, thereafter gradually decreased. 2. Treatments of ethrel only and 50ppm ethrel plus 2000ppm SADH (F block) enhanced the fruit coloring whereas a little enhancement of the coloring was found in the treatment of 2000ppm SADH plus 50ppm GA3 (H block). 3. The fruit firmness was relatively lower in the fruits from the ethrel treatment only and the F block than from the others. In contrast, the firmness of the fruits from the treatments of 25ppm ethrel plus 75ppm GA3 (E block) and H block was relatively higher. Especially a most efficient result for the long-term storage of the fruits was obtained by the treatment of 2000ppm SADH plus 50ppm GA3. 4. In sugar contents, there was generally no significance among the treatments. However, slight difference were found after the fruit transter from the storage temperature to the room temperature: One day after the transfer, the contents in the fruits from the F block showed relatively higher ones; four days after the transfer, the ones in the fruits from the H block and the D block (50ppm ethrel plus 50ppm GA3) were relatively higher. 5. The values of the coerrelation coefficients between the fruit coloring and the fruit firmness were obtained from œ0.73toœ0.85 according to a lapse of the fruit transfer. 6. The chlorophyll contents were relatively higher in the fruits from the two blocks of H and E, while lower from the F block. Generally the contents decreased four days later after the fruit transfer and there was also a similar trend in the contents of chlorophyll a and b. 7. The contents of vitamin C were highst in the fruits from the B block, whereas lowest from the F block. There was a slight decrease in the contents during the fruit storage. However, after drying the fruits at the high temperature, the contents showed a rapid decrease. 8. The major fatty acids of the fruits were myristic acid, palmitic acid and oleic acid Especially hexaoctadienoic acid in the fruits from the two blocks of E and H showed relatively higher contents with 15.36% and 19.82%, respectively. The fruits from no chemical treatment showed relatively higher contents of linolenic acid (21.7%) than ones of the other acids. 9. An unexpected result in the fatty acid composition was obtained from the treatment of paclobutrazol compared to the other treatments: The contents of myristic acid were 97.7%, the ones of palmitic acid 2.3%. It was difficult to explain the result, therefore, a further investigation for the interaction between them in the fruits is needed.
