Archaeological evidence shows that cotton fibres of the genus Gossypium were first used for textile production at Mehrgarh, Pakistan in the Neolithic period ($6^{th}$ millenium BC). Eventually the cotton plant and textiles found their way to Egypt and through there, to Greece. However, the chronological origins of the cultivation and/or use of cotton fibres in textile production in ancient Greece are ambiguous. The main sources of information are ancient written texts and excavated textile finds. Both indicate that the introduction of cotton in Greece can be placed in the mid-first millenium BC. However, it is not clear whether the cultivation of the plant and consequently the production of cotton textiles was established in that period or whether another cotton species was produced and used locally in Greece or whether isolated examples of cotton textiles had been imported in Greece before the cotton plant. A more comprehensive analytical study of surviving textile finds coupled with archaeological research for plant production and cultivation would provide the answer to these questions.

Cotton waste is usually used for cultivating agaric mushroom after outdoor fermentation for a few months. Electron beam was used to break down the polymer chaims of cotton waste for increasing low molecular weight soluble sugars, which may enhance the agaric mushroom cultivation. By increasing electron beam radiation, alpha cellulose content of the cotton waste was decreased while beta cellulose content and hot water solubles were increased. Electron beam radiation over 240 kGy on cotton waste caused significant increase of mushroom yield without lowering mushroom quality.

Main materials used as media for oyster mushroom cultivation are pine sawdust, beet pulp, cotton seed pomace. Increases in the price and the unbalance of demand and supply of cotton seed pomace was often damage to oyster mushroom cultivation farm, so we investigated agricultural by-product to replace the cotton seed pomace for bottle cultivation of oyster mushroom. Treatment of coconut oil meal or coconut pomace delayed incubation period about 3 days compared with cotton seed waste treatment(control), but yield and income index showed similar to each other in three treatment. Consequently coconut oil meal and coconut pomace could select for cotton seed pomace substitute.

This study investigated the characteristics and changes of cotton and silk textile production in Honam district, especially in Gurye, Jella Province from the 1930s to the 1980s. To do this, research method in this study was both literature and fieldwork research and results were as follows. First, in terms of cotton fiber cultivation of Gurye, Chinese Cotton(在來綿) has been substituted for America Cotton(陸地綿) and additionally, Yellow Cotton (黃綿) has been cultivated in the 1930s. Also, in terms of silk fiber cultivation of Gurye, Joseon Silkworm has been substituted for Japanese Silkworm by inflowing the Japanese mulberry tree. Second, in terms of spinning method, cotton spinning has been conducted at every house by an individual tool from the 1930s to the 1950s and has been gradually changed to mechanization by market shop equipped with mechanized cotton gin and cotton whipping tool. However, there have been no changes in silk spinning method from the 1930s to the 1980s. Third, loom type has been changed from the traditional Korean back-strap loom to the treadle loom between the 1930s and the 1940s. Fourth, dyeing was conducted by chemical dyestuff after weaving. The circulation of textile was done through the joint market by Japan in the 1930s~1950s and has changed to the market sales by producers since the 1950s. Fifth, since the 1970s, the outputs of cotton and silk textile of Gurye have been reduced. This was connected with the westernization and the inflow of the synthetic fiber and cloth in cotton and was related to the changes of the nation policy and silk fiber inflow from the china to the Korean farm villages.

This paper introduces the probable regional and long distance trade of cotton goods among the pre-Hispanic Mesoamericans during the Classic (A.D. 200-900) period through the comparison of the available documentary sources. Based on the ethnohistoric data and the archaeological evidences it was found that cotton was used throughout the Mesoamerica by the elite ruling class. However, because cotton could not be grown at elevations above 6,000 feet it was obvious that nations such as Teotihuacan which flourished in the highland of present day Mexico City had to import cotton from the tropical coastal hotlands either through trade or tribute. Several ethnohistorical and archaeological data suggest that urban center in highland Mexico had people employed in weaving the textiles rather than cultivating or spinning cotton. Archaeological evidences such as the workshops used by the craft specialists seemed to be associated with weaving of cotton. Because of the similarity in climatic conditions for marine shells and cotton cultivation, Kolb's model seems to be applicable to the cotton trade of the classic Teotihuacan. Based on Kolb's model, it could be hypothesized that Teotihuacan-Kaminaljyyu-Maya was the indirect trade route connecting the Basin of Mexico and the Mayan regions.

The effects of aeration through lid filters on the hyphal growth of Lentinula edodes (oak mushroom) in sawdust cultivation bags were investigated. The aeration treatment levels were traditional 27 mm hole cotton plugs, cotton balls and combinations of seven hole sizes ${\times}$ two hole positions (up and under) in the lids covering plastic bags containing 1.4 kg sawdust medium at 63% moisture that had been autoclaved for one hour and inoculated with sawdust spawn of L. edodes strain 921. Aeration treatment effects were measured based on the $CO_2$ concentration at the 15th wk, as well as the hyphal growth rate and degree of weight loss of bags every 14 days for 15 wk. In bags with traditional cotton plugs, the $CO_2$ concentration was $3.8{\pm}1.3%$, daily mean hyphal growth was $2.3{\pm}0.6mm$ and daily mean weight loss was $0.84{\pm}0.26g$. In the bags with 15 mm diameter holes, the $CO_2$ concentration was $6.0{\pm}1.6%$, daily hyphal growth was $2.8{\pm}0.2mm$ and daily weight loss was $0.86{\pm}0.4g$. The bags with 15 mm holes had a higher $CO_2$ concentration and lower water loss than bags with other hole sizes, but the hyphal growth was not significantly different from that of other bags. The weight loss of bags increased proportionally relative to the lid hole sizes. Taken together, these results indicate that traditional cotton plugs are economically efficient, but 15 mm hole lids are the most efficient at maintaining hyphal growth and controlling water loss while allowing $CO_2$ emissions.

U.S. had given large amount of cotton to Korea as food aid program since 1945. This cotton aid had negative impact on cotton culture in Korean agriculture. Korean government used counterparts funds (sale proceeds of food aid) not for investment to agriculture sector, but for military budgets. And food aid on program type had influenced general economic policies, which neglected agricultural sector too. Anti-agricultural policy which was helped by U.S. food aid, had caused cotton cultivator an economic loss. So this economic loss had made many farmers abandon cotton culture. But in our times, cotton is cultivated for the purpose of domestic consumption in a few rural villages. The purposes of this study are 1) to analyze the process of spatial reduction of cotton culture since 1945 in regional contexts in Korea, and 2) to identify the function and meaning of cotton culture which does not pay off in agricultural region. Materials for acreage of cotton culture are acquired through the agricultural statistical year book(1952-1989) and census. To clarify the meanings of cotton culture, field survey are conducted in a rural village which is identified as only one where cotton was cultivated in 1993. In these contexts, this study has come to the following conclusions. In the period of under the rule of Japanese Imperialism (1910-1945), G. arboreum, species of cotton which was traditionally cultivated since 1364, had been driven out. And G. hirustun species, which is suitable for the production of highly qualified textile, has been hierarchically diffused by policy. In these period, regional structure of Korean agriculture was reorganized for the provision with food to Japan. Crops leading this dependent spatial structure were rice and cotton. So agricultural region, specialized with cotton, were distributed in the hinterland of the area which is specialized with rice. U.S. cotton aid to Korea began in 1947. U.S. took an interest in agricultural export because of her domestic surplus of cotton. Cotton aid is one mechanism by which U.S government developed agricultural market in recipient countries, Specially in the exchange rates, up-valuation of won to the U.S. dollars made domestic cotton more expensive than cotton imported, Production cost of domestic cotton is higher than Government's purchasing price of cotton which was also more expensive than price of cotton imported. Korean farmer could not help abandoning the cultivation of cotton, and this gave rise to spatial reduction of cotton culture. Spatially, cotton culture was abandoned in early stage of reduction in regions where stand at a disadvantage climatically, and in next stage in regions where other up-land crops which paid off in urban market, eg, fruits, could be cultivated. In the stage of extinction, cotton was cultivated only in area where G. hirustun species was originated in Korean peninsula. This region is not only suitable climatically for cotton culture, but is far away from urban market. Use of cotton produced is not for spinning, but for fillings of comforter. The main purpose of cotton culture in rural village is not for cotton yields, but for increase of production of seasame, which is grown together with cotton as mixed crops. Cotton product are used for domestic consumption and sold out to gin house. Though cotton culture is not paid off, farmer wanted to cultivate continuously for the cultural purpose, and they wanted the cotton culture promotion policy with the goverment subsidy.

This study was carried out to find optimum condition through sterilization methods for cultivation of Neutaribeosut (Oyster mushroom). 1. Yield of additive culture of pine sawdust, cotton and rice hulls at bag­cultivation of Neutaribeosut. was similiar to additive culture of pine sawdust, cotton and pulpe as conventional methods. 2. Yield of Neutaribeosut at low temp. sterilization method as 50 to 6$0^{\circ}C$ and 7days treatment was higher about 18 to 19％ than that of high temp. as 121$^{\circ}C$ and 90 minutes treatment. 3. In case of farmer­cost, low than high temperature sterilization method appeared lowly about 12％. So this method will be of advantage to farmers in both yield and farmer­cost.

This study investigated the characteristics of cotton production of Damyang-gun & Hwasun-gun, Yeongsan River compared with that of Gurye-gun, Seomjingang River in modern times. To do this, research method was both literature and fieldwork research, results were as follows. First, as for cotton fiber cultivation in Damyang-gun & Hwasun-gun, Chinese cotton (在來綿) has been cultivated during Japanese Colonial era unlike Gurye-gun. Especially, Yellow cotton (黃綿) has been cultivated in Hwasungun. Second, as for spinning in Damyang-gun, Hwasun-gun and Gurye-gun, some of cotton spinning process have been gradually changed to mechanization by market shop equipped with mechanized cotton gin and cotton whipping tool since Japanese colonial era. Third, the loom types also, like spinning tools, have been changed from the traditional Korean back-strap loom to the treadle loom in Damyang-gun, Hwasungun and Gurye-gun. Chemical dyeing with chemical dyestuff also has been done since Japanese Colonial era. Fourth, since the 1970s, the outputs of cotton production have been reduced in both Damyang-gun & Hwasun-gun. For Damyang-gun, this has been connected with bamboo craft since the Joseon Dynasty period. So, Damyang-gun has more concentrated on bamboo craft than cotton production. For Hwasun-gun, since Japanese Colonial era, sericulture has been very important. So, Hwasun-gun also has more concentrated on sericulture than cotton production. The main reason to discontinue cotton production in Damyang-gun, Hwasun-gun and Gurye-gun was related to the local choice like economic added value.

Researches on industrial crops in Korea before 1962 were concentrated on fiber crops such as cotton, kenaf, hemp, ramie and flax. Then research works on oil crops, sugar crops and other high income crops were followed. However, no land is shared for the production of kenaf, flax, sugar beet, sweet sorghum and sunflower at present in Korea, while the cultivation of cotton, hemp, ramie and mat rush is decreasing continuously to the marginal point. At present researches are emphasized on oil crops such as seasame, peanut and perilla and high income medicinal herbs of which cultivating acreages are increasing. Numerous varieties were released as a result of active breeding works on industrial crops since 1962, i.e. 3 sesame varieties including "Suweon 21", 3 peanut varieties including "Seoduntangkong", and 6 rape varieties including "Yudal" in oil crops, one cotton variety "Mokpo 7", one hemp variety "MS4-1", and one kenaf variety "Suweon 2" in fiber crops, and two stevia varieties "Suweon 2" and "Suweon II" in sugar crops. Quality improvement of rape seeds and development of hybrid rapes utilizing male sterile lines are the most significant results of breeding works, while the establishment of vinyl mulching cultivation of sesame and peanut are the most successful results in agronomic researches during the last 20 years.re the most successful results in agronomic researches during the last 20 years.
