The study area is situated between 31˚00' ~ 33˚30' N and 122˚30' ~126˚00' E as a part of the East China Sea continental shelf. The distribution of sediment in the study area can be classified three sedimentary types. Modern land derived muddy sediments consisting of silt and mud are distributed at mouth of the Changjiang River. and are also observed the southwest offshore of the Cheju Island. The sandsilt-clay miadre sediments are presented in the outer shelf area. The relict sand are distributed between the mordern and mixture sediment. The inner-shelf mud consisted of 8.89% sand. 59.05% silt. 32.06% clay and mean size of 6.90Φ. The offshore mud composed of 5.83% sand. 34.54% silt. 59.63% clay and mean size of 8.32). and also have higher water content and organic carbon. The C/N ratio showed higher in the inner-shelf mud (10.14) rather than that of the offshore mud (8.68). Most of the Changiiang River suspended matter is entrapped in the area around the Changjiang Estuary to the west of 123˚30' E. Only a small part of the suspended matter can be moved by Changjiang Diluted Plume to the southeastern and northeastern middle shelf. The higher suspended matter concentration gradient zone are observed in the northwest central region, and this plume zone separated from Changjiang Estuary by a low oncentration of less than 5 mg/ l or 15 mg/ l. The sediment accumulation rate in the inner shelf mud deposit near the mouth of the Changjiang River is 1.70 cm/yr and characterized by physical stratified mud. The sedimentation rate in the offshore mud deposit to the southwest of Cheju Island shows 0.28 cm/yr and characterized by homogenous mud. The difference in fine-scale stratigraphy is explained by the ratio of mixing rate to accumulation rate, which is much larger for the offshore mud deposit (27.34) than for the inner shelf mud deposit (1.65). these larger ratio allows biological mixing to destroy physical stratification.

수확후 전처리 및 저장온도가 절화 백합의 개화와 품질에 미치는 영향

서정근,김지희 한국국제농업개발학회 2004 韓國國際農業開發學會誌 Vol.16 No.1

전처리와 저온저장이 절화백합의 개화와 품질에 미치는 영향에서 BA 분무처리 후 20℃ 저장은 각 소화의 개화와 노화 속도가 빨랐으나 Promalin침지 처리는 개화와 노화정도가 늦게 진행되었다. 또한 수분 흡수량과 생체중에 있어서도 Promalin 처리시 증가하였으며 특히 수분 흡수량은 20℃ 저장보다 5℃ 저장에서 크게 증가하였다. 생체중은 절화수명 초기에 침지 처리후 20℃ 저장시 감소되었으며 Promalin을 침지하거나 분무 처리 후 생체중의 증가는 절화수명을 증가시키는데 크게 연관됨을 알 수 있었다. The effects of pre-treatments and storage temperature on flowering and quality of cut Lillium oriental hybrid 'Casa Blanca' were studied. The flowering and senescence degree were accelated by stored at 20℃ after BA spray treatment, but delayed with Promalin dip treatment. Water uptake was increased by stored at 5℃ as compared to that of at 20℃, especially water uptake was increased by Promalin treatment. Fresh weight was increased by Promalin treatment, and also increased in the beginning storage of vase, and then decreased gradually. When florets of cut lily was treated with stored at 20℃ after distilled water dip treatment, vase life was decreased, but increased with stored at 5℃ after Promalin dip or Promalin spray treatment. The vase life was increased when water uptake and fresh weight were increased.

This study is intended to determine the optimum marketing time for grain products; rice and barley. The farmer has been faced apparently uncertainty caused by weather variation, price fluctuation and technological changes. Hence, one of the most important functions of individual farmer is to set up an optimum strategy for marketing time for the products they produce. Moreover, nonsystematic price variation over season is found especially in the case of grain products, in the short run are affected by the time and amount of grain import, price policy, expectation of the coming products, and so on. Thus, this study is decided to provide farmers as well as grain dealers with some information about the optimum marketing time which secures a maximum profit as greatly as possible, when price uncertainty has been taken into account, under assumption of several storage cost levels including the interest, risk, and the like. In other words, the game theory models have been applied to the monthly time series data of rice and barley prices for this objective. All price series are expressed in 1965 constant price, and are converted into November and July present price for rice and barley, respectively, when the storage costs have been considered. The results can be summaried as follows; 1. Rice marketing strategy a) Maximin criterion Interest rate Strategy selected (%) Single strategy Mixed strategy 0 Sell in Aug.

These results are suggest that the governments purchasing policy is effective in the sense that price is comparatively equalized to season for rice. However, barley puchasing policy seems to weak to equalized the price level over season thus far. Moreover, rice price control policy by government caused a destruction of marketing channel which is function of merchant under the society of capitalism. As mentioned above, it would be too sweeping to say that the results are always proper to every individual farm, because selection of the strategy for a farmer will likely depend on his psychological make-up.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

Although transplantation immunology as a distinctive field began with the development of experimental models that showed the feasibility of bone marrow tranaplantation (BMT), organ engraftment was accomplished first in humans, and was though for many years to occur by drastically different mechanism. The liver, skin, and gastrointestinal tract are major target organs of acute graft-versus-host disease (GVHD), the major complication of allogenic BMT. The pathophysiology of acute GVHD involves in the dysregulation of pro-inflammatory cytokine cascade and donor T-cell responses to host alloantigens. Interukine-l8 (IL-18) was initially known as interferon-g-inducing factor with potent immunomodulatory effects. The level of IL-18 is increased in acute GVHD, but little has been known about its role in thepathophysiology of acute GVHD. It reduces the severity of acute GVHD as a Thl-inducing cytokine early after BMT to the lethally irradiated recipients. When administered to the donor, it can also reducing the severity of acute GVHD, as a Th2-inducing cytokine. Therefore, IL-18 has the remarkable capacity to modulate acute GVHD when administered either to the donor or the recipient through distinct mechanism. Here, we present our view of the concepts of transplantation immunology and the role of IL-18 in the graft rejection.

Recently large scale cooperative rice production system has been promoted. This cooperative rice production system is intended to promote introducing a set of new technology which may not be suitable for individual small scale farms to adopt. And this system is believed to be one of important public programs to achieve productivity growth policy goal in Korea. Nevertheless, there seem to exist several problems for this public program to widely introduce to over-all nation. This is one of main objectives that this study intends to investigate. In order to study comparative characteristics of the large scale rice cooperative farm in terms of resource base and organization 99 farms which are member farms and 100 farms which are non-member individual farms have been selected and interviewed from five large scale cooperative farm areas in Gyeong-Nam Province in 1974. The important findings can be summarized as follows: 1) Most of operators af both classes belong to age cohert 40∼50, but the average educational level for member farm operators is higher than that for non-member. 2) The average scale Of rice paddy for member farms, 13.1 tanbO, is larger than that for non-member, 10.6, and the same thing is true for average size of rice paddy plots which is, respectively, 805 pyeong and 690. 3) Completely irrigated paddy for member farms is 99 percent of total paddy owned whereas that for non-member is 81, and consolidated paddy for member farms is 67 percent while that for non-member is 26.4. On the other hand, technically improved paddy other than indicated above for member farms is 32 percent, but that for non-member is only 8.3. 4) Number of rice varieties adopted is 9 for both classes. The most popular variety for member farm is Akibare(36%) whereas that for non-member is Sadominori(29.3%) and Akibare (28.4%). 5) Labor used is 13.5 man per tanbo for member farms and 12.4 for non-member. More labor is used for improving soil quality and protection for member farms whereas less labor is used for preparatory works such as seed bed, sterilization, and water management in the case of the member farm. 6) In the case of member farms, the type of work which is achieved cooperatively by more than 70 percent is purchasing or exchaging seeds, sterilization, and plant protection. Despite seed bad, water management, transplanting and the like being more or less suitable for cooperative work, the proportion of those works done cooperatively is relatively small as compared to what we expected. 7) According to farmers interviewed, variety selection, plant protection, seed bed, transplanting fertilization, water management, and harvesting works are more easier for cooperation, in order importance. 8) Cooperative farmers were cultivating a leading variety, Tongil, which showed higher yields than ordinary varieties and had a desire to be released a new high yielding variety which has a characteristics of highly resistance to dsease and insect. 9) Cooperative farmers were forced to begin the nusery bed earlier than the individual farmers and to emphasize on the disease and insect control with more frequencies. 10) Cooperative farmers had benefits in the seedling transplanting earlier and higher planting density than individual farmers. 11) Cooperative farmers had an intention to apply a deep fertilization method arid to dress heavier nitrogen with a reasonable ratio of the basal fertilization to the top dressing. 12) Cooperative farmers had a convenient irrigation system and were available to adopt a summer drainage method. 13) Cooperative farmers controlled the weed with agricultural chemicals arid recognized the control effect of weedcides. 14) In general, it was recognized that there happened somewhat benefit result in disease control in the cooperative farm while a reasonable control effect was not found in heavy prevailing case. The dominant diseases found in the cooperative farm were sheath bright, strip disease and they were to he prevented with a strong efforts. 15) Rice stem borer and grass leaf roller were effelctivey controlled in the cooperative farm, however, plant hoppers was not completely controlled by the usual method because of its unexpected prevalence. 16) The most difficult thing to cooperate they indicate is to supply an adequate amount of labor at appropriate time in tire labor peak season. In this sense, it seems necessary to introduce field machinary in order to achieve the objective of large scale cooperative rice production. 17) Farmers interviewed believe that technology concerning yield increase is most important. in this respect, it is important to develop such new technology, to diseminate its results and to train good quality extension workers. 18) 42 percent of member farm operators indicate that the cooperative system was successful and 25 percent indicate failed. 29 percent of non-member farmers think that the cooperative farm system was successful and 7 percent of them think failed. Thus 55 percent of non-member farmers indicate they are willing to join to the system in the next year, 7 percent of them are not and others have not decided yet. 19) 60 percent of member farmers think that the scale and number of members of the system were too much large to successfully cooperate and 67 percent of them believe that cooperation among members were not very developed, and 42 percent of members suppose what the leader of individual active farms were not very well functioning. 20) Number of member farmers who believe that the yield level in this year is increased as compared that before joining to the system is 3,4 percent, and no one indicated that the yield level is decreased. On the other hand, 22 percent of them believe that by participating to the system the same quality of paddy could produce more rice. 21) About 93 percent of member farmers believe that the system may not lie survived without support of government and i priority must be given to yield technology. 22) About 80 percent of member operators indicate that they would partioipate to the program in the next production year and 23 percent of them indicate that they would participate with the same amount of paddy land as this year. 23) The rice yield level for member and non-member farms is, respectively, 406kg and 346 per tanbo, and the former is 17.3 percent higher than the latter. 24) The cash expenses per tanbo for member and non-member farms is, respectively, 12,311 won and 10,398. 25) The gross revenud per tanbo for both classes is, respectively, 60,024 won, and 51,303 when evaluated by the official price level, and the net income is, respectively, 47,713 won and 40,905. As seen above, the fact that the rice yield level of member farmers, hence, the income level turns out to be higher seems to stem from two basic factors; that is, on the average, the member farmers are operating farm with an improved resource base and they seem to use more the so called conventional inputs with a better yield technology and management. Thus we may conclude that it is important to invest to improve resource quality, to innovate new yield technology and diseminate this innovation. At the same time, in order to more promote the cooperative system, it seems desirable to solve the following problem areas: 1) Number of member farms and paddy area covered by one cooperaitve unit seems better not to he very large. This seems so because there is on much scale economies owing to the nature of technology available to adopt, whereas a large member unit may restrict opportunity of individual members to deeply involve in the process of decision making. Thus we recommend to continue to study finding an optimum size of the unit. 2) As implied already, quality as well as quantity of extension workers and other local officers who lead this program area crucial factor to expand number of unit of the system and hence to achieve the objective of the program. 3) In order to get rid of labor deficit, especially in the labor peak season farm mechanization seems necessary. For this matter, it is worthwhile to promote, first of all, to invent suitable field machinery, secondly, land consolidation and other land improvement projects, and thirdly to innovate a new technology system suitable to mechanized farming. At any rate, it is also necessary for the government to supply an adequate amount of credit and other administrative support.
