The purposes of this study were to identify the contents, frequency of use, and the rationales of folk remedies frequently used for first aid at home for stomachache, vomiting, strain, food poisoning, vaginal bleeding, or wounds of snake or dog bite, or bee sting. As the method of the study, data were collected by conducting a questionnaire of 185 persons, who filled it out or who were interviewed from May to August in 1998. The collected data was analyzed by using frequency and the rationales for the contents of the folk remedies were described base on literatures. The results were as follows,. 1. The folk remedies for stomachache in frequency order were 'warming the abdomen', 'rubbing the abdomen with a hand', or 'pricking a finger to bleed', which have the rationals. 2. The folk remedies for vomiting in frequency order are 'drinking water of watery radish' and 'pricking a finger to bleed', which have the rationales. 3. The folk remedies for strain in frequency order are 'soaking the affected area into cold water or applying an ice pack' and 'after soaking jasmine in water, making a dough with flour, and then attaching it on the affected area', which have the rationales, Additionally, although the frequencies are low, 'drinking brewed Achyranthis Radix' and 'applying brewed leaves and stalks of Sambuci Cortex' have the rationales. 4. The folk remedies for food poisoning in frequency order are 'drinking black beans and licorice brewed together' and 'eating mung beans', which have the scientific grounds. 5. The folk remedies for bloody discharge in frequency order are 'drinking brewed lotus root' and 'eating boiled chicken stuffed with root of bell-flower'. However, 'drinking brewed Thujae orientalis Folium' has the rationales. 6. The folk remedy for snake bite wounds that has the scientific grounds is 'sucking blood by a person without hurt in the mouth'. However, quite a lot of people apply alum or soy paste, which has no rationales. 7. The folk remedies for the bee sting in frequency order are 'after removing the sting, applying soy paste or sauce' and 'applying saliva'. No rationales for 'applying saliva' have been found. 8. The folk remedy for the dog bite wound that has the rationales is 'applying juice of leaves or stalks of Xanthii Fructus'. However, 85% of surveyed people use remedies that have no scientific grounds, such as 'applying burnt dog hair mixed with (sesame) oil' and 'applying soy paste or sauce'. Various materials are used in folk remedies for first aid treatment as shown above. Some of the folk remedies have the rationales since their medicinal actions have been found. However, the medicinal actions of the majority have not been found, but only known that they are effective, Especially for the materials except botanical drugs, they are used without knowing the effects since their components and pharmacognosies have not been described in any literature. The results of this research may be used for materials to educate the surveyed people or to consult them. Accordingly, the folk remedies that have the rationales are required to continue to study to find out the effects.

This study is based on data from the nutritional and clinical survey in Chung Nam area, namely Myl-Yang-Ri, Yoon-Gok-Myon, Chyung Yang Koon. Under the direction of two Nutrition professors and two clinical pathology professors it was carried by 35 Dae Jeun medical Junior College students majoring in nutrition and clinical pathology from 18 July to 25 July 1978. The nutrition surveys were carried out with subjects in village from a total 67 households, 36 of them were randomly selected. The clinical surveys were carried out with subjects in village from a total 382 inhabitant, 154 inhabitant were randomly selected and 109 peoples were subjected to stool examination. The results obtained in this study are summarized as follows. 1) Nutritional survey a) Food Intake The average food intake per person per day in survey area was 929.9 grams (95.5% in vegetables and 4.5% in animal foods). The average consumption of the basicfood groups per person per day was 965g for meats and legumes (10.4% of the total food in take). 268.9g for fruits and vegetables (29% of the total food intake), 559.1g for cereals and potatoes(60.1% of the total food intake), 5.2g for milk and small fishes and 0.2g for fats and oils. b) Nutrient Intake The average daily consumption of calories and nutrients was 2054.1 kcal and 61.2g for total proteins, 223.2mg for calcium, 9.5mg for iron, 4914.4 IU for vitamin A, 1.5mg for thiamin, 1.2mg for riboflavin, 19.9mg for niacin and 54.7mg for ascorbic acid. When these figures are compared with the recommended allowances for Korean, the calories and nutrients intakes were insufficient. Especially the intakes of the calcium were lower than the recommended allowance which are 500 milligrams per day. c) Kinds of food stuffs consumed The kinds of food stuffs consumed by the subjects were 47 figures total. Generally these kinds of food were vegetables food. 2) Clinical Survey a) The mean value of hemoglobin from 72 males was 13.2g/dl, that of 82 females was 12.3g/dl. b) The proportion of low hemoglobin (<12.2g/dl for male and <11.3g/dl fo female) for male was 20.8%, females was 11.0% and from 24 male & female (both sexes) were 15.6% c) The mean value of Hematocrit of males was 39.6%, that of females was 37.4%. d) The mean value of MCHC of males was 33.9%, that of females was 33.6%. e) The ABO blood group was distributed as following; 30.5%, for group O, 29.2% for group A, 24.0% for group B, and 16.3% for AB group.

Fermented medical herbs using Lactobacilli have attracted significant attention due to their enhanced biological activities. A traditional medicinal plant, Artemisia annua L., was fermented using a probiotic strain, L. plantarum SK3494. The strain was isolated from Artemisia princeps var. orientalis and molecularly identified through sequence similarities and phylogenetic tree analysis. The antioxidant activity of L. plantarum-fermented A. annua L. (LFA) was determined using the DPPH free radical scavenging assay. Cellular antioxidant activity of LFA was examined using the superoxide radical reduction assay in MAT-C cells. Total polyphenol contents (TPC) and flavonoid contents (TFC) of LFA were determined. The antibacterial activity of LFA against fish pathogens was also determined in this study. The viable cell number (9.38 log10 CFU/ml) and pH (4.1) results showed good adaptive ability of the selected strain during fermentation. LFA was found to have enhanced antioxidant activity compared to non-fermented A. annua L. (NFA) based on the DPPH assay. Cellular antioxidant activity was present in both LFA and NFA. After 24 hr and 48 hr of fermentation, the LFA also showed antibacterial activities against fish pathogens Photobacterium damselae subsp. damselae and Vibrio ichthyoenteri. These results suggest that L. plantarum-fermented A. annua L. may have potential as a feed additive in aquaculture.

This study, as a purpose of base study for landscape redevelopement of Seowon, pointed out problems of planting patterns in each sector and suggested an alternative through analyzing old literature, complete enumeration survey in each sector and taking aerial images. the conclusions drawn from this study are as follows. A Pilam Seowon(historic site no 242) is located in a Pyungya-Sanrok(plain and mountain) district in Jangsung-gun and has Junhak-Humyo(Study room in the front and Shirne in the back) type. 23 taxonomic group of arbor, 6 taxonomic group of shrub and 5 taxonomic group of flowers are planted high-densitily in limited flat surface. It can be classified into being planted by family and being planted through landscape redevelopement in 1980s. Korean traditional trees are planted in this area like Pinus densiflora, Juniperus chinensis L., Thuja orientalis L., Zelkova serrato Makino, Sophora japonica L., Lagerstroemia indica, Prunus mume include Ginkgo biloba which is old big tree and is registered in Jangsung-gun as protected trees. The tea tree in this area was introduced from wild tea plantation in Yonhwa moutain and was planted. From now on, we have to pay consideration a form management of planted trees in the historical area, rearrangement of plant density due to over planting, removal of alien trees like Pinus bungeana and Canna generalisa, prevention a dwarfishness of main area due to over planting in outside facilities, recovery a alienation among each planting area, and planting concept from plants drawings on wall of buildings can be suggested. The implications of this case study is that introduction of over planting can make more problems like losing sense of place. Therefore, we must do a actual state survey on traditional landscape area like Seowon from preservation point of view.

Background: The composition of wild bird populations in temperate zones greatly varies depending on phenological changes rather than other environmental factors. Particularly, wild birds appearing in wetlands fluctuate greatly due to the crossover of species arriving for breeding during the summer and for wintering. Therefore, to understand the changes to species composition related to phenology, we conducted this basic analysis of populations to further the cause of the protection of wetland-dependent wild birds. Methods: It is wrong to simply divide a wild bird population investigation into seasons. This study identifies species composition and indicator species that change along with seasons. Wetlands to be surveyed are protected by natural monuments and wetland inventory and are in a state close to nature. In order to identify as many species as possible in wetlands, a survey was conducted in both shallow and deep wetlands. The water depth varied in these areas, ranging from 0.2 to 2.0 m, allowing for both dabbling and diving ducks to inhabit the area. Surveys were conducted using line-transect and distance sampling methods and were conducted at intervals of 2 weeks. The survey was conducted under the following three categories: the eco-tone and emergent zone, the submergent zone, and the water surface. The survey was conducted along a wetland boundary by observing wild birds. A PC-ord program was used for clustering, and the SAS program was used to analyze the changes in species composition. The data strongly indicates that day length is the main factor for seasonal migration periods, despite the fact that climate change and increasing temperatures are often discussed. Results and conclusions: The indicator species for determining seasons include migrant birds such as Ardea cinerea, Alcedo atthis, Anas penelope, and Poiceps ruficollis, as well as resident birds such as Streptopelia orientalis and Emberiza elegans. Importantly, increases in local individual counts of these species may also serve as indicators. The survey results of seasonal fluctuations in temperate zones shows that spring (April to June), summer (July to September), autumn (October), and winter (November to March) are clearly distinguishable, even though spring and summer seasons tend to overlap, leading to the conclusion that additional research could more clearly identify fluctuation patterns in species composition and abundance in the study area.

To determine the status of Korean molluscs infection and relation with climate change of Korean peninsula, references were reviewed. Wild animals serve as intermediate, reservoirs and paratenic hosts to zoonotic parasites of human beings. Trematode are common parasites of molluscs and almost all trematodes infect mollusks as the first host in the life cycle, and most have a complex life cycle involving other hosts. The significance of auxiliary hosts to the ecology of the parasite has not been proper discussion. There is increasing concern as to the impact of climate change on the epidermiology of many parasitic diseases. A total of 21 species for snail transmitted parasites from Korean molluscs has been reviewed. Among them, 15 species was aquatic mollusks and 6 species for marine mollusks. Maximum infections belonged to Semisulcospira livertina had 11 kind of parasite pathogenic organisms, including Paragonimus westermani, Metagonimus yokogawai, Centrocestus armatus, Notocotylus magniovatus, Centrocestus formosanus, incerte cercaria, nipponensis cercaria, Yoshidae cercaria, cristata cercaria, innominatum cercaria and Metagonimus sp. And 11 in Parafossarulus manchouricus including Clonorchis sinensis, Asymphylodora japonica, Cyathocotyle orientalis, Exorchis oviformis, Notocotylus attenuatus, Echinochasmus japonicus, Loxogenes liberum, Cercariae of Loxogenes liberum Type I, Cercariae of Loxogenes liberum Type II, Furcocercus cercariae (Family Sanguincolidae) and Cercaria of Mucobucaris, 10 in Semisulcospira sp. including Paragonimus westermani, Metagonimus yokogawai, Centrocestus armatus, Echinochasmus redioduplicatus, Notocotylus magniovatus, Cercaria incerte, Cercaria nipponensis, Cercaria yoshidae, paludinarum cercaria and Metagonimus sp., 7 in Koreanomelania globus including Pseudexorchis major, Cercaria of parapleurolophocercous type, Metagonimus sp. (A & B), Cercaria nipponensis, Cercaria inserta and Cercaria yoshidae. Also, Tapes philippinarum have 3 pathogenic organisms including Cercariae tapidis, Cercariae furcocercus and Parvatrema sp. In particular, under climatic extremes such as floods and drought, aquatic molluscs may play a more prominent role in parasite transmission in the future.

Hibiscus hamabo, called "Hwang-geun", growing about 3m in height is a deciduous shrub or subtree of Malvaceae. Because the number of these species is very limited in the world, the Ministry of Environment has designated H. hamabo as a preserved plant. The Korea Forest Service also protects it strictly by law since H. hamabo is an out-of-the-way plant and possibly may be exterminated soon in Korea. Investigation for distribution and ecological characteristics of the habitat for H. hamabo was carried out on Soan Island. Two wild H. hamabo were found at the forest edge (equation omitted) along the sea coast located in the southern part of Soan Island and this was the first report in the Korean academic world. These two wild H. hamabos were growing in a naturally inhibited area. The diameters at the base were 12cm and 15cm. The Tree heights were 150cm and 210cm and the number of branches of each wild H. hamabo was 4 and 7. However, the present condition of these plants was not good. Environmental conditions of the naturally inhibited area of H. hamabo were very mild because it is located at the edge of the forest and is always sunny during the daytime since the slope of the inhibited area is facing South. The ground drained very well since the soil was made of gravels and sand. Because the percent of vegetation of the subtree layer where H. hamabo was growing was 40%, the cover degree and sociability of flex crenata trees and Eurya japonica were found to be high. In the naturally inhibited area of H. hamabo, a dominant value of Rubus parvifolius in the lower part of the herb layer was very high and many plants in Compositae, such as Artemisia princeps var. orientalis and Erigeron annuus, were also present. A dominant value of liana, such as Vitis thunbergii var. sinuata, Rosa multiflora, Clematis terniflora and Hedera rhombea, and Gramineae plants that rhizomes were well developed and aggressively propagated, such as Miscanthus sinensis var. purpurascens, Phragmites communis, Spodiopogon cotulifer and Oplismenus undulatifolius which were surveyed as high, too. These results imply that H. hamabo might be exterminated soon through a natural selection if the proper management of the naturally inhibited area of H. hamabo is not conducted continually.

This study was evaluated about the seasonal variations of ecosystem in Nammae Reservoir based on the interrelation of physico-chemical characteristics, nutrients, chlorophyll a, b, c and standing crops of phytoplanktons. The amounts of chlorophyll a, b, c were respectively maximum (295 mg/, 9.5mg/l and 48mg/l) at station 1 in June and the standing crop of phytoplanktons was the highest ($1.7{\time}10^5$ cells/1) at stations 3 in July. The range of temperature was $7{\sim}37.4^{\circ}C$. The maxium of pH was $9.9{\sim}10.1$ at all stations in August, the minimum was 7 in September. SS was maximum (308 mg/1) at station 1 in June, while it was minimum (4 mg/l) at the same station in November. The maximal COD and DOC were 33 mg/1 and 16 mg/1 respectively at station 1 in June. As for phytoplanktons, Microcystis aeruginosa, blue-green alga in July${\sim}$August, Scenedesmus acutus, green alga in March${\sim}$May and November${\sim}$January and Cyclotella orientalis, Diatoms in October were dominant species. The amounts of P and Si were generally high in summer, they were low in autumn and winter. Nammae Reservoir assessed by trophic state index was eutrophicated and overtrophicated. These results indicated that Nammae Reservoir was faced with heavy water pollution. As preceding management for the basin of the Reservoir, it will have to be continually studied for an ecosystem reservation.

The authors observed the ultrastructure of the mucous glandular epithelial cells in the amphibian skin by mean of electron microscope. The specimens from the experimental animals were fixed in 2.5% glutaraldehyde-oaraformaldehyde fixative in phosphate buffer at pH 7.2 prior to fixation in 1% osmium tetroxide, dehydrated in graded ethanol and acetone, embedded in Epon 812 mixture, and sectioned with Sorvall MT-2 ultramicrotome. The ultrasections were contrasted with uranyl acetate and lead citrate and observed with a JEOL-100B electron microscope. The results were as follows: 1. The cutaneous mucous glands in amphibia consisted of the glandular epithelial and the myoepithelial cells. 2. Several different cells in ultrastructure were observed in the mucous glandular epithelium of the adult amphibian skin. a. The dark and the light cells were observed in Hynobius leechi. b. The mitochondria-rich and the round secretory granule-containing cells were observed in Bombina orientalis. c. The round secretory granule-containing and the foam-like granule mass-containing cells were observed in Kaloula tornieri. d. The cutaneous mucous gland of Rana nigromaculata were divided into two types: A and B-type glands. In the A-type mucous gland, the mitochondria-rich and the round secretory granule-containing cells and in the B-type mucous gland, the mitochondria-rich, the secretory granule-containing and the ER-rich cells were observed. 3. Based upon the above findings, the authors infer that the mucous granular epithelium of the amphibian skin consists of the mitochondria-rich undifferentiated, the secetory granule-containing and mature, and the ER-rich evacuated cells.

The present study was conducted as part of basic research for selecting species of street trees with historical value in Seoul. It also made up a list of traditional landscape trees for a variety of alternatives. The following results are shown below. As to the history of street trees in Korea, records on to-be-estimated street trees are found in historical documents written in King Yangwon during the second year of Goguryeo Dynasty (546) and King Myeongjong during 27 year of Goryeo (1197). However, it is assumed that lack of clarity is found in historical records. During the 23 year of King Sejong in the early Joseon Dynasty (1441), the record showed that the state planted street trees as guideposts on the postal road. The records revealed that Ulmus spp. and Salix spp. were planted as guidance trees. The street tree system was performed in the early Joseon Dynasty as recorded in the first year of King Danjong document. Pinus densiflora, Pinus koraiensis, Pyrus pyrifolia var. culta, Castanea crenata, Styphnolobium japonicum and Salix spp. were planted along the avenue at both left and right sides. Morus alba were planted on streets during the five year of King Sejo (1459). As illustrated in pieces Apgujeong by painter Jeongseon and Jinheonmajeongsaekdo in the reign of King Yeongjo, street trees were planted. This arrangement is associated with a number of elements such as king procession, major entrance roads in Seoul, place for horse markets, prevention of roads from flood and indication. In the reign of King Jeongjo, there are many cases related to planting Pinus densiflora, Abies holophylla and Salix spp. for king procession. Turning king roads and related areas into sanctuaries is considered as technique for planting street trees. During the 32 year of King Gojong after opening ports (1985), the state promoted planting trees along both sides of roads. At the time, many Populus davidiana called white poplars were planted as rapidly growing street trees. There are 17 taxa in the Era of Three Kingdoms records, 31 taxa in Goryeo Dynasty records and 55 taxa in Joseon Dynasty records, respectively, described in historical documents to be available for being planted as street trees in Seoul. 16 taxa are recorded in three periods, which are Era of Three Kingdoms, Goryeo Dynasty and Joseon Dynasty. These taxa can be seen as relatively excellent ones in terms of historical value. The introduction of alien plants and legal improvement in the Japanese colonial period resulted in modernization of street tree planting system. Under the six-year street tree planting plan (1934-1940) implemented as part of expanding metropolitan areas outside the capital launched in 1936, four major street trees of top 10 taxa were a Populus deltoides, Populus nigra var. italica, Populus davidiana, Populus alba. The remaining six trees were Salix babylonica, Robinia pseudoacacia, platanus orientalis, Platanus occidentalis, Ginkgo biloba, and Acer negundo. Beginning in the mid- and late 1930s, platanus orientalis, Platanus occidentalis were introduced into Korea as new taxa of street trees and planted in many regions. Beginning on 1942, Ailanthus altissima was recommended as street trees for the purpose of producing silks. In 1957 after liberation, major street tree taxa included Platanus occidentalis, Ginkgo biloba, Populus nigra var. italica, Ailanthus altissima, Populus deltoides and Salix babylonica. The rank of major street tree species planted in the Japanese colonial period had changed. Tree planting trend around that period primarily representing Platanus occidentalis and Ginkgo biloba still holds true until now.
