This survey was performed to investigate the distribution of specialities which cultivated importantly in Jeollabukdo area in order to understand food culture of this area. Foods in speciality were divided into 4 groups, agricultural, aquatic, animal and the others products. Total number of 93 species of specialities, including 40 species of agricultural products, 29 species of aquatic products, 8 species of animal products and 16 species of the miscellaneous products, were identified from Jeollabukdo area. Especially, there were various fruits and vegetables among agricultural products and fishes among aquatic products in this region. Rice, pepper, pear, Mandarin fish, beef, pine mushroom, lentinus edodes and honey were determined as specialities in Jeollabukdo area. Various aquatic products were specialities in Gochang, Gunsan, Buan and Gimje region. Fruits, mushrooms, wild edible greens and animal products were specialities in Muju, Jangsu, Jeongeup and Jinan. Sweet fish, cat fish and freshwater crab were caught off in Sumjin river region only such as Namwon, Sunchang and Imsil, Recently, pumpkin(Cucurbita maxima) and paprika were determined as specialities in Jeollabukdo. In case of aquatic products, mushrooms and wild edible greens, their wild type products decreased, while cultivated type increased Commercialization by brand naming of agricultural and animal products were rapidly increasing. The kinds of specialities in Jeollabukdo area were changing by the influence of geographical, religious and social factors.

This treatise deals with chronic state of famine and exploitation of famine relief food in the later half of Chosun Period and especially in relation with socio-economic changes. There with the impact of socio-economic factors on the chronic state of famine and exploitation of famine relief food is studied mainly with a literary approach. The influential factors which lead to the chronic state of famine were not only climatic restrictions such as flood and drought but socio-economic factors such as foreign invasion (Japanease invasion and Ching's invasion), frequent breaking out of revolt and technological development of agriculture (rice transplantation). And disorder of land system and cultivation of cash crops by the richer peasantry, lowering the economic status of the poorer peasantry who were a major constituents of the population, aggravated the famine state. Because the poorer peasantry were under the shortage of food, they had to seek something edible in the fields and mountains. In this process various kinds of famine relief foods were exploited by the poorer peasantry. The majority of famine relief foods were wild vegetables. Consequently the Chronic state of famine was a cause to introduce various edible wild vegetables into Korean food, which influenced modern vegetarian food habits and firmed the Korean's favorite taste to be hot and salty. These wild vegetables couldn't have a marvelous effect on the relief of starved people. Potatoes and sweet potatoes, which were newly introduced foreign crops, were encouraged to be cultivated for famine relief. But these tubers, unable to be staple food, didn't contribute to an increase in population.

Background: Several studies have reported that wild mushrooms contain high amounts of radioactive cesium (137Cs). After the Fukushima Daiichi Nuclear Power Plant Accident, a significantly high concentration of 137Cs has been detected in wild mushrooms, and their consumption may be the cause of the chronic internal exposure of local consumers to radioactivity. Therefore, an accurate evaluation of the internal radioactivity resulting from mushroom ingestion is needed. Materials and Methods: The 137Cs elution rate through the cooking and digestion stages was evaluated using in vitro experiments. The edible mushroom Pleurotus djamor was taken as a sample for the experiments. The mushrooms were cultivated onto solid media containing 137Cs. We evaluated the internal dose based on the actual conditions using the elution rate data. For various cooking methods, the results were compared with those of other wild edible mushrooms. Results and Discussion: From the elution experiment through cooking, we proved that 25%-55% of the 137Cs in the mushrooms was released during soaking, boiling, or frying. The results of a simulated digestion experiment after cooking revealed that almost all the 137Cs in the ingested mushrooms eluted in the digestive juice, regardless of the cooking method. The committed effective dose was reduced by 20%-75% when considering the dissolution through the cooking process. Conclusion: We found that cooking lowers 137Cs concentration in mushrooms, therefore reducing the amount of radioactivity intake. Besides, since there were differences between mushroom types, we demonstrated that the internal exposure dose should be evaluated in detail considering the release of 137Cs during the cooking stages.

With well-being boom recently, the common people, but not experts, are increasingly taking in them directly by picking wild herbs. However, only experts can distinguish between edible vegetables and poisonous herbs from the wild herbs. Especially, it is not even easy for experts to distinguish them only by looking into buds in spring without flowers or fruit. So, sometimes many patients are being carried into the emergency room by the toxic symptom after taking by misunderstanding the poisonous herbs as edible vegetables. For herb intoxication as well as drug intoxication, what kinds of vegetables patients took in, and when and how much they took in them are important information for curing. Of course, in the case of intoxicating in the wild herbs, the patients can have a lot of symptoms and sings-hemodynamic alteration and abnormal neurologic sign as well as gastrointestinal symptoms-according to the kinds of herbs which they took in. Therefore, it is difficult to find the kinds of herbs which they took in through the specific symptoms. Recently we experienced a case with showing typical anticholinergic symptoms after ingestion of Scopolia japonica. As a result, the publicity activities about the wild plants needs because if the person without their previous knowledge take in the poisonous herbs, serious side effects can be produced..

This study was performed to provide reference materials for the vegetable cultivating farmhouses by investigating profit and marketing situation for the folk vegetables. The survey areas covered 10 cities and counties including Kumsan, 72 farmhouses, and 8 crops including buffterbur and wild rocambole. As a result, the cultivated area of folk vegetables was increased as much as 13.7%, however, marketing cost was higher than that of horticultural crops, because they were not accessed to wholesale market. It was that the optimal period to sell the folk vegetables was shown like Jan. - Feb. for butterbur and day lily, Nov. - Dec. for wild rocambole, and Oct. - Nov. for kind of lettuce respectively. As the result of analyzing economical efficiency, the net profit per 0.1 ha was amounted to 3,438,000 won for butterbur, 3.291,000 won for wild rocambole 1,712,000 won for day lily, and 1,464,000 won for fatsia shoots. Besides, these four crops occupied more than 60% in cultivation area, and their profit was high. Therefore, it is necessary to foster them with special crops in Chnugnam area. The crops that require more labor time were such crops as 632.9 hours for day lily, 584.3 hours for butterbur, and 409.2 hours for fatsia shoots, whereas the crops that required less labor time were such field crops as 219.2 hours for fragrant edible wild aster and 233.8 hours for kind of lettuce.

This study was designed to compare the lipid components between wild and cultured snakehead, Channa argus. The lipid components of cultured snakehead were analyzed and compared with that of wild snakehead. In both edible portion and viscera, the lipid content in cultured, snakehead was higher than that in wild one. In the fatty acid composition of neutral lipid in edible portion, percentages of $C_{14:0},\;C_{16:0},\;C_{18:1},\;C_{20:5},\;C_{22:5}\;and\;C_{22:6}$ in cultured snakehead were higher than those in wild one, while percentages of $C_{18:0},\;C_{16:1},\;C_{18:2},\;C_{18:3},\;C_{20:4}\;and\;C_{22:4}$ lower. In the case of phospholipid in edible portion, percentages of $C_{16:0},\;C_{18:1}\;and\;C_{22:6}$ in cultured snakehead were higher than those in wild one, while percentages of $C_{16:1},\;C_{18:2},\;C_{18:3},\;C_{20:4},\;C_{22:4}\;and\;C_{22:5}$ lower. The unsaturation (TUFA/TSFA) and w3 highly unsaturated fatty acid content (w3 HUFA) of neutral lipid in cultured snakehead were higher than those in wild one, while those of phospholipid lower. The essential fatty acid contents (TEFA) of both neutral and phospholipids in wild snakehead were higher than those in cultured one. In the ratio (A/B) of fatty- acid content (A) in cultured snakehead to that (B) in diet, the A/B ratios of $C_{18:2\;w6},\;C_{18:3\;w3},\;C_{20:5\;w3}\;and\;C_{22:6\;w3}$ were 0.3 to 2.5 times, and it is considered to be related to the biosynthesis of polyenoic acids and growth rate of cultured snakehead.

The study was performed under the various conditions, such as the edible parts and particle sizes of Allium, the concentrations, the temperatures, and the pH of heavy metal solutions to investigate their adsorption capacity of heavy metals by genus Allium. The adsorption amount of Cd by Allium in the aqueous solution was apparently higher than that of Zn by them. The larger the particle size of welsh onion and shallot was, the higher the adsorption of Cd was. But the adsorption ratio was not different. As the temperature increased, the amount of heavy metal adsorption increased in general, but the adsorption of Cd by wild garlic, Zn by garlic decreased. Adsorption of Cd and Zn to Allium was not affected by the various pH. The correlation between the amount of components in edible putts of Allium and that of adsorption of heavy metals was significantly high in amino acids containing sulfhydryl radical (-SH) and vitamin B2.

This study was conducted to obtain the basic information of edible resources among plant species. Potentials of resource plants were important in various usages, healthy food, medicinal materials, and breeding materials. Through our investigation 609 species of resources plants were considered as edible resources. These species belong to 74 families in which Asteraceae, Poaceae, Fabaceae, and Rosaceae were major families. Brassicaceae, Liliaceae, and Asteraceae contained large numbers of edible plants because plants belonged to these families were mainly used as vegetable. But Cyperaceae and Poaceae had relatively small numbers of species in the category of edible plant because plants belonged to these families have not been used directly as vegetables, common usage of edible plant. But Poaceae have a potentials as genetic donor for resistance-breeding strategies in major cereals. Although Poaceae can not be used as food directly, Poaceae should be investigated intensely in future for improvement of major cereals or application as fodder plants. The beneficial traits of edible plants as breeding materials have not been studied yet and development of new crop from plant resources requires the information about current situation in occurrence of resources plants genetically related to current crop species. Our results do not cover all plant species in Korea but this classification and identification about edible resources will provide primary information about plant resources. The collected seeds of resource plants showed wide spectrum in germination rate among plant species. The germination rate would probably be affected by collecting times, collected stage, and stored period. The proper methods about improving germination rate have to be elucidated to propagate the resource plants.

This study was carried out to establish a proper cultivation condition and diagnose the drought-tolerance of three wild edible greens belonging to genus of Ligularia by using pressure-volume curves methods. The result of the original bulk osmotic pressure at maximum turgor ${\Psi}_{\circ}{^{sat}}$ was -0.8 MPa in Ligularia fischeri and L. stenocephala, which was somewhat lower than the value, -0.7 MPa, in L. fischeri var. spiciformis. In addition, the values of the osmotic pressure at incipient plasmolysis ${\Psi}_{\circ}{^{tlp}}$ in L. fischeri and L. stenocephala, both of which were -0.9 MPa, These were slightly lower than that of -0.8 MPa in L. fischeri var. spiciformis. On the other hand, it appeared that the values of maximum bulk modulus of elasticity $E_{max}$ of L. fischeri and L. stenocephala were approximately two times higher than that of L. fischeri var. spiciformis. However, There was a distinct difference between the values of the relative water contents in these three species. Therefore, Ligularia spp, occurring incipient plasmolysis in the high water contents, have a relatively low property of drought-tolerance, suggesting that growth of those Ligularia spp. are appropriate for relative moisture forest.

This experiment was carried out to select some herbicides for edible wild greens, Album monanthum, Petasites japonicus, and Aster scaber. The herbicides tested were napropamide 21.8% EC, nitralin 50% WP, and pendimethalin 31.7% EC. Dorminant weeds in the field were Echinochloa crus-galli, Digitaria sanguinalis, Persicaria hydropiper, Chenopodium album, and Siegesbeckia pubescens. Simpson's index was calculated to 0.26~0.30, which showed that weed occurrence in the field was quite various. Control efficacy in the field treated with napropamide EC 872g(ai/ha)., nitralin WP 1,000g(ai/ha), and pendimethalin EC 634g(ai/ha) were 81.4%~85.6%, 79.4%~82.8%, and 86.8%~92.2%, respectively. The typical phytotoxic symptoms to herbicides were germination inhibition, growth retardation, and malformation.
