This study repeated low-frequency transcranial magnetic stimulation (rTMS) to evaluate the effects on cognitive function in chronic stroke patients. Among the chronic stroke patients, 30 patients selected by MMSE-K and BCRS-K were divided randomly into 3 groups. Group I (n=10) had only sound applied, group II (n=10) were applied 1 Hz rTMS on the damaged side and group III (n=10) were applied to 1 Hz rTMS on the opposite side for total 2 weeks, 20 minutes per a day, five times per a week. To examine the change in cognitive function, CREAD-K scores were measured before, 1 week, 2 weeks, and then 3 months after the intervention. The CREAD-K scores were measured before and 1 week, 2 weeks and 3 months after the interventions. The immediate recall memory showed a significant difference after 2 weeks and 3 months in groups II and III (p<.05), The recognition memory showed a significant difference after 2 weeks and 3 months in group III (p<.05). The delayed recall memory showed significant differences after 3 months in group III than in group I (p<.05). Therefore, the application of low-frequency rTMS has a positive influence on the cognitive rehabilitation of chronic stroke patients.

A plant diversity, which consists of indigenous plant community with Orientla thuja community (Natural monument no. 1) in Dodong, Daegu, is identified and analyzed as ecological characteristic to consider worth plants and vegetation resource of the region. The vascular plants of Thuja orientalis community were listed as 219 taxa (3.7% of all 4,881 taxa of Korean vascular plants); 67 families, 147 genera, 199 species, 16 varieties, and 4 forms. Vulnerable species (VU) and least concerned species (LC) were recorded based on IUCN standard; Koelretueria paniculata (VU), Thuja orientalis (LC), and Exochorda serratifolia (LC). Although the study site is a non-limestone area, a total of 15 taxa of calciphilous plants were identified; Cheilanthes argentea, Hypodematium glandulosopilosum, Asplenium retamuraria, Thuja orientalis, Spiraea blumei, Smilax sieboldii, etc. A total of 4 taxa endemic plants were identified; Prunus mandshurica for. barbinervis, Lespedeza maximowiczii var. tomentella, Forythia koreana (artificial origin), and Veronica pyrethrina. Among the list, 8 taxa of naturalized plants were identified; Fallopia dentatoalalta, Rumex crispus, Nasturtium officinale, Bidens frondosa, Erigeron annuus etc. Naturalization rate (NR) was 3.6%, of all 219 taxa of vascular plants and urbanization index (UI) was 2.2% of all 321 taxa of naturalized plants. Thuja orientalis occupies a lot of indigenous landscape in this study area which is the southern-limited part of a natural distribution where it can survive. The T. orientalis community, where indigenous plants have formed a characterful species composition based on habitat, has been confirmed as a worth national vegetation resource in an indigeous flora. It has been considered of plans for persistent conservation.

The fairy tale 'The King's Ass's Ears' is a simple story about a king and a barber. The king's 'Ass's ears' is discovered by the barber, who becomes sick due to his inability to reveal the secret. He eventually confesses the secret in a deep pit and covers it with soil, but a reed grows in that spot and reveals the secret when it sways in the wind. This fairy tale is registered in Stith Thompson's narrative type AT 782 as 'King Midas and His Ass's Ears', corresponding to a well-known story of King Gyeongmun in Korea, as it is published in elementary textbooks. When something becomes conscious, its automatic mechanical tendency leads to obsolete and rigid. To avoid rigidity in our conscious life, we need continuous renewal via contact with the flow of mental events in our unconscious. From the aspect of analytical psychology, the King's 'Ass's ears' enables irrational contact with the fundamental emotions lost in the flow of life. The barber symbolizes spiritual transformation, and the reed swaying in the wind symbolizes the revelation of secretive knowledge associated with the divine. The king can hear the sound of all creation and become one with it, which was the will of the divine. The Self, as the psychic totality of an individual and paradoxically also represents the regulating center of the collective unconscious, continually seeks to merge and transform with the lost primal layer of humanity, which has now become distant and discarded due to the development of human consciousness.

In order to observe an effect of the components of rice straw on the utilization of nutrient in chicks, the rice straw of 100g were digested in 800$m\ell$ of distilled water or 0.25N NaClO$_2$ at 135 C and in the pressure of 3.2kg/$\textrm{cm}^2$ by autoclave during 30, 60 and 120 minutes (water or NaClO$_2$-30, 60 and 120- RS). The contents of neutral detergent fiber(NDF), acid detergent fiber (ADF) and lignin were analysed in the washed and dried rice straw meal. Hatched single comb white Leghorn male chicks were fed with a commercial chick mash for the first 10 days and five kinds of experimetal diets for the next 8 days which contained 17.0% of wheat bran (basal), cellulose(cotton meal), nontreated RS, water-30-RS and NaClO$_2$ 30-RS, respectively. The water-30, 60 and 120-RS baa leased 9.7, 12.1 and 13.3% of dry matter, respectively, while NaClO$_2$-30-RS had similar contents of dry matter loss with those of water-30-RS, and NaClO$_2$-60 and 120-RS had tossed 1.5 times of dry matter comparing with those of water-60 and 120-RS, respectively. And the dry matter loss of the water-RS or NaClO$_2$-RS was mainly originated front the extractable cell contents and hemicellulose of the non-treated RS. Birds fed water-30-RS diets had higher body weight gain and lower feed conversion than those of birds fed non-treated and NaClO$_2$-30-RS diets during 8 days of experimental feeding. Also nitrogen balance and retention rate of birds fed water -30-RS was higher comparing with those of birds non-treated and NaClO$_2$-30-RS. And digestibility of crude fat had been shown a highering trend in birds water-30-RS. The rate of metabolizable energy (MEn) to gross energy (GE) of birds fed non-treated RS, water-30-RS and NaClO$_2$30-RS diets were 71.9, 72.9 and 70.4%, respectively, and energy intake per metaboic body size (kg 0.75) were reached to 307.3, 296.2 and 291.4 kcal per day, respectively. And daily protein retention per kg 0.75 were 1.647, 1.969 and 1.560g, respectively. Then 30.56kcal of MEn required for 1 g of protein retention in birds fed water-30-RS, which was lower thu 36.90 and 37.56 kcal of birds fed non-treated and NaClO$_2$-30- RS, respectively. The results seems to indicate that non-treated rice straw had a substance or characters which affect the energy unilization or protein retention of diets and which will be eliminated by boiling in water.

The resource plants of the Mt. Geonji was listed 354 taxa; 92 families, 242 genera, 303 species, 48 varieties and 3 forms. 354 taxa listed consists of 205 taxa of edible plants(57.1%),234 taxa of medicinal plants(65.2%), 167 taxa of ornamental plants(46.5%) and 218 taxa of the others(60.7%). Specific plant species by floral region were total 22 taxa; Trapella sinensis var. antennifera in class IV, Iris ensata var. spontanea in Class II, 16 taxa(Salix glandulosa, Alnus hirsuta, Chrysosplenium flagelliferum, Mallotus japonicus, Ilex macropoda, Grewia biloba var. parviflora, Vaccinium oldhami, Lysimachia barystachys, Fraxinus mandshurica, etc.) in class I. The naturalized plants in this site were 12 families, 23 genera, 28 species, 2 varieties, 30 taxa(Bromus unioloides, Phytolacca americana, Oenothera erythrosepala, Ipomoea hederacea var. hederacea, Aster pilosus, Erechtites hieracifolia) and naturalization rate was 8.5% of all 354 taxa vascular plants. Wild plants disturbing ecosystem like Solanum carolinense and Ambrosia artemisiifolia var. elatior have been increasing. So, it needs continuing control and conservation measures on the plant ecosystem.

Forty one samples from thirty three species of algae (19 from 15 species of Rhodophyceae, 18 from 14 species of Phaeophyceae, 3 from 3 species of Chlorophyceae, and 1 of marine Phanerogams) collected from several locations on the east, west and south coast of Korea, were analyzed for their contents of crude protein, fat, cellulose, ash, nitrogen free extract, amino nitrogen, and total amino acids. For the examination of extractability of algal protein with water, 4 species of algae, Sargassum thunberggi, Grateloupia filicina, Phyllospadix japonica, and Sargassum confusum, were analyzed. And the effect of some precipitation treatments for isolation of algal protein was also tested. As a matter of fact, Rhodophyceae showed high content in crude protein and low in crude fat while the case was opposite for Phaeophyceae and Chlorophyceae. Refering to the content of crude protein and total amino acids, the recommendable algae for protein sources were Sargassum thunbergii, Acrosorium flabellata, Phacelocarpus japonicus, Laurencia okamurai, Laurencia intermedia, Grateloupia filicina, Chondrus ocellatus, Gloiopeltis furcata, Gigartina tenella, Dictyota dichotoma, and Scytosiphon lomentaria. Methanol treatment appeared most effective in precipitation isolation of protein from water extracts whereas pH control method did not so beneficial. The precipitation rate of protein was particularity higher in the extract of Sargassum confusum ana the lowest was makted from the extract of Sargassum thunbergii.

Optimum pasture management during the summer season is an important factor to maintain good regrowth and persistence of pasture in Korea. This experiment was carried out to investigate the effects of the cutting management on the dead plant, weed appearance, regrowth and carbohydrate reserves in stubble, and dry matter yield of tall fescue dominated pasture during the mid summer season. For the test, a split plot design with 4 replications was treated with 2 different the third cutting times (July 12 and Aug. 4) as the mainplots, and 3 different cutting heights (3, 6 and 9 cm) at the third cut as the subplots, and the experiment was done at the experimental field of the Livestock Experiment Station, in Suweon, 1984. The results obtained are summarized as follows: 1. Considering the meteorological conditions during the experimental period, the temperature was a little higher by $2^{\circ}C$ than that of average year, especially the first and second decade of August were high. And the precipitation of 1984 tended to be low when compared with the average year. 2. Temperature of soil surface and underground tended to increase by $1-3^{\circ}C$ as the stubble height was low during the summer season. 3. Regrowth leaf length and leaf area after the third cut increased significantly with the high cutting height at the third cut. 4. A significant higher total nonstructural carbohydrate (TNC) content in stubble after the third cut was observed in the high stubble cut on July 12. The results indicate that the high stubble height reserves more carbohydrates for early regrowth stage after the third cut when compared with the low stubble. On Aug. 4, however, the recovery of TNC contents after the third cut was not effective due to high temperature and rainfall. 5. The percentage of dead plant after the third cut was found to be high with the low cutting height during the mid summer season (p<0.05). 6. With the low stubble height on July 12 cut, it was appeared that the percentage of weed was significantly increased (p<0.05), and main weeds appeared after the third cut were Echinochloa crusgalli>Digitaria sanguinalis>Cyperus iria>Rumex crispus, and so on. In case of cut on Aug. 4, weed appearance was no difference at three cutting heights. 7. Dry matter yield at the third cut was increased in the plot of cutting on Aug. 4 and stubble height (p<0.05). However, yields at the fourth and fifth cut were increased with high stubble height (p<0.05), regardless of harvest time. 8. In total dry matter yield after the third cut, there was no significant difference between the cutting time and forage yield. However, total yield on July 12 was increased with the high stubble height (p<0.05). 9. From the above results, it is suggested that the 9 cm cutting height during the mid summer season is the most effective for good regrowth, weed control and forage yield of tall fescue dominated pasture.
