Colonialism heretofore described merely as a political economic phenomenon denotes another aspect, namely, an ecological imperialism that accompanies the biological implantation of human beings, crops, weeds, domestic animals, and pathogens onto colonized lands. Foremost, the Korean Peninsula during the colonial period served as a testing ground for the transplanted Japanese varieties of rice. Near the mid-1940s, the new varieties came to dominate over 90% of cultivated rice paddy. The speedy diffusion of transplanted rice was attributable to the aggressive promotion of agricultural institutions led by the Institute of Agricultural Tests and Experiments. Various policies and tactics were also instrumental to the nationwide distribution of new varieties, and they included naming recommended varieties, sponsoring rice contests, establishing crop inspection offices, educating young farmers at training camps, and publishing newsletters for agricultural societies. The forward and backward linkages that came along with the new varieties of transplanted rice helped to consolidate colonial status quo and to create hybrid agricultural landscapes in the Korean countryside.

The Iymphoproliferative disease after the organ transplantation is more commonly seen with the increase according to the increasing number of the organ transplantations and it occurs more frequently in the cases of heart and lung transplantations that needs more aggressive immunosuppression. It demands urgent evaluation and management because of poor prognosis. We transplanted left lung of a man to the woman who suffered from severe dyspnea due to terminal pulmonary emphysema in discrepancy of ABO blood type. Postoperatively, We used triple regimen immunotherapy(cyclosporin, azathioprine, prednisolone) and followed up in the out patient clinic. During the follow up, we found abnormal mass lesion on the transplanted lung and performed gun biopsy. We confirmed malignant lymphoma on the pathollgic examination and two cycled chemotherapy was given after reducing dose of immunosupression. The patient died of sudden onset of pulmonary edema of the transplanted lung.

This experimental Study was designed to investigate the effects of Acanthopanacis Cortex Extract(ACE) on the immunity, anti-cancer and obesity in mice. The results were as follows; ACE was significantly increased in the proliferation of thymocytes and splenocytes, and NO production from peritoneal macrophages in normal mice. ACE was significantly increased in the proliferation of thymocytes and splenocytes, and NO production from peritoneal macrophages in L1210 cells transplanted mice. ACE was significantly decreased in the proliferation of L1210 cells in L1210 cells transplanted mice. ACE was significantly inhibited body weight and tumor weight in S-180 cells transplanted mice. ACE was significantly increased in the mean survival days in S-180 cells transplanted mice. ACE was significantly decreased in the body weight in rats fed high fat diet. ACE was significantly decreased in the serum total cholesterol level, free fatty acid level, total lipid level, phospholipid level in rats fed high fat diet. According to above results, the authors suggest that ACE is able to be used for the herb of physiological-action.

Seed production of italian ryegrass has a problem of lodging during ripening and a decrease in quality due to difficulty in drying seeds during harvest. Therefore, in order to produce high-quality Italian ryegrass in paddy fields, it was carried out to reduce the density and solve the lodging problem through transplanting. In this experiment, Lolium multiflorum cv. Kowinearly was transplanted in autumn from a paddy field in Sindong-ri, Gwansan-eup, Jangheung-gun, Jeollanam-do. var. Kowinearly was made into a bed at 90 g/box and stacked in boxes. It was transplanted on October 27th after 2 days of germination at 30℃ and 15 days of seedling and greening. When transplanting, they were transplanted at intervals of 30×14cm. The existing cultivation method, drill seedling, was sowed at a level of 50 kg/ha, and both transplanting and drilling were carried out at a nitrogen fertilization rate of 45 kg/ha. The number of ears during transplant cultivation was 1,016/m² and the drilling tended to be higher at 2,278/m², but this was probably due to the difference in seeding amount. The seed number of an ear tended to be 56% higher in transplantation, which had a significant impact on yield. The seed yield was 2,096 ka/ha in transplantation, which was 21% higher than that of drilling. When looking at the relationship with weed occurrence, there were areas where all the weeds, such as amul foxtail, occurred due to the low density. Even in the same transplanting area, the seed yield was about 1,000kg/ha less in the area where the weeds were abundant. It seems that weed management is important in paddy cultivation. Therefore, it seems necessary to develop an exclusive herbicide for Italian ryegrass cultivation.

Therapeutic efficacy of mesenchymal stem cells (MSCs) is determined by biodistribution and engraftment in vivo. Compared to intravenous infusion, biodistribution of locally transplanted MSCs are partially understood. Here, we performed a pharmacokinetics (PK) study of MSCs after local transplantation. We grafted human MSCs into the brains of immune-compromised nude mice. Then we extracted genomic DNA from brains, lungs, and livers after transplantation over a month. Using quantitative polymerase chain reaction with human Alu-specific primers, we analyzed biodistribution of the transplanted cells. To evaluate the role of residual immune response in the brain, MSCs expressing a cytosine deaminase (MSCs/CD) were used to ablate resident immune cells at the injection site. The majority of the Alu signals mostly remained at the injection site and decreased over a week, finally becoming undetectable after one month. Negligible signals were transiently detected in the lung and liver during the first week. Suppression of Iba1-positive microglia in the vicinity of the injection site using MSCs/CD prolonged the presence of the Alu signals. After local transplantation in xenograft animal models, human MSCs remain predominantly near the injection site for limited time without disseminating to other organs. Transplantation of human MSCs can locally elicit an immune response in immune compromised animals, and suppressing resident immune cells can prolong the presence of transplanted cells. Our study provides valuable insights into the in vivo fate of locally transplanted stem cells and a local delivery is effective to achieve desired dosages for neurological diseases.

In order to find out better cultivation practices in mid-mountainous area to produce high quality rice, an experiment involving four transplanting times and four varieties was carried out, during past three years $(2002\~2004)$. There was no significantly different on palatability of rice between transplanting time, but an interaction effect was between transplanting time and variety, The palatability of milled rice of Sangmibyeo, Hwayongbyeo and Junambyeo transplanted at May 10th were higher than Samcheonbyeo. The palatability of milled rice grown by May 20th day's transplanted, Sangmibyeo and Junambyeo were higher than Samcheonbyeo. The palatability of milled rice grown by May 30th day's trans-planted, Sangmibyeo and Hwayongbyeo were higher than Samcheonbyeo and Junambyeo. And the palatability of milled rice grown by June 9th day's transplanted, Sangmibyeo and Samcheonbyeo were higher than Hwayongbyeo and Junambyeo. It can infer that Sangmibyeo is one of the best option over the transplanting times in term of palatability, Amylose content of milled rice was showed without a significant difference between transplanting time, but there was an interaction effect between transplanting time and variety. The amylose content of grown by May 20th day's transplanted, Sangmibyeo and Samcheonbyeo were lower than Junambyeo. The amylose content of milled rice grown by June 9th day's transplanted, Sangmibyeo and Samcheonbyeo were lower than Hwayongbyeo and Junambyeo. And the amylose content of milled rice grown by May 10th day's and May 30th day's transplanted, was showed without a significant difference between variety. The protein content of milled rice grown by later season transplanted was lower than grown by earlier, The head rice yield wasn't different significantly between the treatment of transplanting times and varieties. But the yield of milled rice grown by transplanted at May 20th day was high most in between the treatment of transplanting time. In a conclusion gathering all above the results, 20th May day's transplanting time and Sangmibyeo was one of the best option for producing high quality rice among the treatments in considering with head rice yield, palatability, amylose${\cdot}$protein content and productivity, at Mid-mountainous area.

In mid-April, 2000, hundreds of thousands of fish floated dead on the Chungnang River, one of the small branches of the Han River in Seoul. We examined the causes of the accident in detail, through analysis of monitorinq data from the Han River Monitoring Project, which employed the transplanted aquatic moss, Fontinalis antipyretica. This allowed investigation of another possible cause of the fish kill: release of trace metals into the river from industrial sources during the rainfall event. In addition, we aimed to verify the usefulness of aquatic mosses as bioindicators of the event. Water samples collected 48 h after the fish kill exhibited low pH and high Total-N and Total-p, indicating that acidic compounds rich in nitrogen and phosphorus might be a major contaminant. BOD and COD were also very high. On the whole, the conditions of the river water were degraded at that time. Distinct trends were not observed in the chlorophyll phaeophy-tinization quotient and photosynthesis rate of transplanted mosses. How-ever mosses sampled soon after the accident exhibited the lowest values for those variables (P < 0.01), suggesting that stress factors in the river were diluted out over time. Heavy metals with characteristics of industrial effluents (Cr, Pb, Zn, Fe, Cu, and Cd) increased (p ＜ 0.01), indicating that they were unlikely to be major causes of the accident.

Purpose: This study was aimed to investigate the health related quality of life and related factors of organ transplant recipients. Method: The participants were 188 people who had liver(86), kidney(81), or heart(24) transplanted. Data on the demographic characteristics, transplantation-related characteristics, symptom frequency or discomfort measured by Transplant Symptom Frequency and Symptom Distress Scale by Lough et al(l987), and health related quality of life measured by SF-36(version 2) were collected. Result: Overall health related quality of life score was 492.1 for 100scoring and, 344.9 for norm based. Physical functioning showed the highest quality of life score (77.5) and vitality showed the lowest(51.l). The kidney transplanted showed the highest quality of life (504.4) and the heart transplanted showed the lowest(426.7) Quality of life was related with occupation(p=.016) and symtom discomfort(p < .0001). Conclusion: The health related quality of life of transplated patients was lower than the norm of American. Further studies need to be done to identify the norm of Korean and to investigate the effect of releving symptom discomfort on the increasing the health related quality of life.
