This paper focuses on the Bijombon Haerampeon written by Lee Eonjin The analysis of the paper is associated with the following: i) the career of Lee Eonjin ; ii) the manuscripts and collected works of Lee Eonjin ; iii) Haerampeon ; iv) Lee Yeonghyu and Nam Ok ; v) and the comparison of the Bijombon Haerampeon and Haerampeon carried in Songmokkwanjip and Songmokkwansinyeogo. Lee Eonjin(1740-1766) was a great poet and better known as one of the four great interpreters in Chosun dynasty. Woosangingbok was the only manuscripts handed down up to now among the works of Lee Eonjin. Woosangingbok ran the Bijombon Haerampeon, 6 pieces of itinery, 3 pieces of poem, 5 pieces of letter. Lee Eonjin visited Japan from the 6th of October, 1763 to the 20th of June in 1764 as a member of Tongsinsa in attendance upon Cho Om. He wrote Haerampeon vividly with five characters what he observed during his stay in Japan. It was composed on board of Ilkido from the 28th of May to the 8th of June in 1746. After Lee Yeonghyu and Nam Ok reviewed Haerampeon, Lee Yeonghyu placed a blue point and circle and Nam Ok placed a red point and circle. Ultimately the result raised the value of Haerampeon. Haerampeon is to be divide into four parts. Four parts are described below: the first part, the geographic features and products of Japan; the second part, the grow of Osaka city and the cityward tendency of world products; the third part, the racial prejudice, religion, and life; and the fourth part, the good neighborly relations with Japan. Finally, as compared with the proofing and difference of three kinds of text, namely, the Bijombon Haerampeon and Haerampeon carried in Songmokkwanjip and Songmokkwansinyeogo, it is approved that the Bijombon Haerampeon is the most correct text and has the value of cultural properties as a national treasure. The Result of this research will be contributed for research Lee Eonjin and utilized as information resources in the field of bibliographic science, Korean language and literature, and historical studies, etc.

This experiment was conducted at National Yeongnam Agricultural Experiment Station in 1995 to identify effects of early flooding in dry seeded rice on rice growth and weed occurrence. The early flooding of emergence date and the 2-leaf stage were not differed significantly on seedling stand, seedling growth of rice and plant characteristics associated with lodging compared to flooding of the 4-leaf stage. However, weed occurrence resulted in 39-61% suppression. Most predominant weed regardless of flooding times was Echinochloa crus-galli, followed by Aneilema japonicum. The Aneilema japonicum, in general, was higher occurrence with earlier flooding, while dry land weeds such as Digitaria sanguinalis, Stellaria alsine etc. reduced. Grain yield of early flooding at emergence date and the 2-leaf stage was higher by 2-5% than that of the 4-leaf stage due to better grain filling ratio and heavier 1,000 grain weight.

To supply seeds with a good quality as plant materials for herbicide screening and to know whether the germination characteristics could be associated with a differential response to herbicides, germination characteristics and differential responses to herbicides were investigated with 3 species of a genus Setaria ; Yellow foxtail(Setaria glauca P. Beauv, SETGL), Giant foxtail(Setaria faberi Hetrm, SETFA), and Green foxtail(Setaria viridis P. Beauv, SETVI). Degree of dormancy was high in the order of SETGL, SETVI and SETFA. The dormancy of SETGL seed was relatively well removed by room temperature and drying storage, but SETFA and SETVI by low temperature and wetting storage(stratification). For breaking dormancy of SETGL, SETVI and SETFA, it was necessary for being kept under the above storage conditions for at least 2, 4 and 4-5 months, respectively. When the dormancy-breaked seeds were transfered to low temperature($4^{\circ}C$) and drying condition, SETGL showed germination rate of 96% even after 2 month storage. However, SETVI and SETFA showed a decreased germination of 54% and 69%, respectively, with a decreased velocity of germination, indicating that secondary dormancy might be induced. On the other hand, a significant change in germination rate was not observed as the seeds were transfered to room temperature($25^{\circ}C$) and drying condition. The germinability of SETGL seed began to decline from 6th year after storage in room temperature and drying condition. All of 3 species showed relatively high germination rate at alternating temperature of $30^{\circ}C$/$20^{\circ}C$(14hr/10hr) and their germination were not increased by light. All of 3 species exhibited similar responses to cycloxydim, sethoxydim and primisulfuron in greenhouse experiment. In contrast, SETVI and SETFA were relatively susceptible to fenoxapropethyl, SETFA to fluazifop-butyl, SETGL and SETFA to clorimuron-ethyl, and SETGL to EK-2612. The difference in herbicidal response among 3 species was the highest in the treatment of EK-2612. These results suggest that there is no a consistent tendency in responses of 3 species to herbicides which have the same target site. And the relationship between germination characteristics and differential responses to herbicides was not found.

It is assumed to be an efficient method for keeping a germinability of weed seeds as long as possible, if a secondary dormancy is not induced by transferring the seeds of which dormancy was broken in wetting condition into drying condition. To investigate its validity, two experiments were carried out on seeds of 9 weed species ; to find out the most effective storage condition in breaking the dormancy of each weed species and to know whether there is a decrease in the germinability by transferring into drying storage condition. The dormancy of Chenopodium album and Stellaria aquatica was released well under the drying condition, but that of Echinochloa crus-galli var. oryzicola by soaking in water. Other weed species were released from dormancy by storage in wetting condition. When the seeds stored in the wetting or soaking condition, are air-dried and then restored at room or low temperature, a decreasing tendency of germinability which might cause a trouble in using them practically, was not observed except on the seeds of Persicaria vulgaris. In the case of Persicaria vulgaris, the low germination since 3 month-storage seemed not to be caused by drying, because a decrease of its germinability was observed with increasing storage period in all of the storage conditions. In contrast, high germination was induced as the seeds of Echinochloa crusgalli var. oryzicola, which were not germinated during the storage in low temperature and wetting condition, were transferred into the room temperature and drying condition. These results suggest that this approach can be one of the efficient methods for keeping a good germinability as long as possible in most weed seeds.

Ten-day-old seedlings of the oxyfluorfen-tolerant and -susceptible rice cultivars with barnyardgrass, a typical susceptible weed were soaked in oxyfluorfen at $10^{-6}M$ for 2 hrs kept for 24 hrs in the dark, and exposed to light for 0, 2, 4, or 6 hrs to investigate changes in the activity and isozyme of antioxidative enzymes. The activities of antioxidative enzymes of APOX, CAL, POX, NR, GR, MDAR and SOD in the tolerant and susceptible rice cultivate themselves didn't show any difference but the activity in the susceptible barnyardgrass was very low in comparison with rice cultivars. The activity of lipoxygenase tended to be some slightly higher in the susceptible rice cultivars and barnyardgrass than in the tolerant rice cultivars. The activities of MDAR, POX, GR and SOD, antioxidative enzymes, were higher in the tolerant rice cultivars than in the susceptible rice cultivars and barnyardgrass after the treatment of oxyfluorfen. After the treatment of oxyfluorfen, in the change of POX isozyme, the activity of C band in the tolerant rice cultivars increased with increased concentration but it didn't in the susceptible rice cultivar. The activity of B band decreased slightly at $10^{-4}M$ in the susceptible barnyardgrass. Isozyme of GR, SOD and AO by the treatment of oxyfluorfen, the activity of each band between the tolerant and susceptible rice cultivars showed no difference but GR isozyme C band was disappeared in the susceptible barnyardgrass at $10^{-4}M$. In the change of esterase isozyme resulting from the treatment of oxyfluorfen, the activities of B, C and D bands decreased more in the susceptible rice cultivars than in tolerant rice cultivars, and A band was disappeared in the susceptible barnyardgrass at $10^{-4}M$.

This study was carried out to investigate the optimal condition for multiple propagation through leaf tissue culture and to apply anther culture techniques to Pulsatilla koreana Nakai breeding. Leaf and anther of Pulsatilla koreana Nakai were cultured on MS, MT, LS and $B_5$ media supplemented with several growth regulators and nitrogen sources under various conditions. For callus induction and differentiation from the Pulsatilla koreana leaf segments were more effective in the combination of zeatin and auxin than auxin alone. The color of the callus was green when treated with IBA alone. Shoot differentiation was more effective when treated with zeatin than auxin alone, especially the best hormoal combination for shoot differentiation was zeatin 1.0mg/l +NAA 0.1mg/l, while 2,4-D inhibited shoot differentiation. The appeared rate of S pollen was 35% in vivo, while that of S pollen by low temperature$(4^{\circ}C)$ pretreatment for 4 days was increased by 53% and the optimum culture time for callus induction from anther was uni-nucleate stage. $B_5$ basal medium supplemented with NAA 0.5mg/l and zeatin 1 mg/l was the most effective on callus formation and the best results of plant regeneration were obtained from combination of NAA 0.5mg/l and zeatin 0.5mg/l in anther culture. $NH_{4}NO_3$ as more effectives as the nitrogen source than $KNO_3$ and the combination with zeatin 2.0mg /L was the best effective. The best combination for plant regeneration in callus induced from anther was $NH_{4}NO_3$ 1650mg/l + $KNO_3$ 3800mg/l + zeatin 2.0mg/l. Ploidy level of anther-derived plants appeared 28% haploid, 47% diploid and the others were triploid, tetraploid and mixploid. In compare with E.S.T, M.D.H and P.X banding patterns were distinguished among callus, haploid and diploid plants in electrophoresis.

Diabetes mellitus is the fifth leading cause of death among Koreans. Control of hyperglycemia and dyslipidemia is strongly correlated with decrease in risks for cardiovascular diseases, the most common and fatal diabetic complication. The effects of chronic feeding of a mixture of Chinese herbs on blood lipid profile were measured in an animal model of type 2 diabetes mellitus, db/db mice (C57BL/Ks). The Chinese herb mixture was composed of Panax ginseng C. A. Meyer,Astragalus membranaceus, Glycyrrhiza uralensis, Lycium chinense, Morus, Pueraria thunbergiana, Prunella vulgaris var. lilacina, Acanthopanax sessiliflorus, Schizandra chinensis, Scutellaria baicalensis, Dioscorea batatas, Polygonatum doratumvar. pluriflorum, Paeonia lactiflora, and Rehmannia glutinosa in a ratio of 1 : 0.7 : 0.4 : 0.7 :0.4 : 0.7 : 1.1 : 0.9 : 0.4 : 0.4 : 0.7 :0.7 : 0.9 : 0.9. Methanol extract of the Chinese herb mixture was tested for the inhibitory activity against yeast ${\alpha}$-glucosidase in vitro. The Chinese herb mixture extract inhibited ${\alpha}$-glucosidase by 25.2% at the concentration of 0.5mg/mL. Four weekold male db/db mice (n = 14) were fed AIN-93G semipurified diet or diet containing 10% powder of the Chinese herb mixture for 6 weeks after 1 week of adaptation period. Body weight (39.5 ${\pm}$ 1.6 g) and food intake (4.3 ${\pm}$ 0.6 g/day) of the Chinese herb group were not significantly different from those of the control group (40.4 ${\pm}$ 2.6 g and 4.5 ${\pm}$ 0.6 g/day). Consumption of Chinese herb mixture significantly decreased plasma glucose level (442.5 ${\pm}$ 36.0mg/dL) compared with the control group (489.8 ${\pm}$ 34.6 mg/dL, p < 0.05). Plasma cholesterol level (159.2 ${\pm}$ 18.4 mg/dL) of the Chinese herb group was significantly lower than that of the control group (185.4 ${\pm}$ 13.7 mg/dL, p < 0.05). Blood glycated hemoglobin (6.3 ${\pm}$ 0.8%) and plasma triglyceride levels (99.4 ${\pm}$ 15.0mg/dL) of the Chinese herb group were not significantly different from those of the control group (6.7 ${\pm}$ 0.7% and 108.8 ${\pm}$ 11.0mg/dL). Thus, the Chinese herb mixture could be useful in the treatment of diabetes and cardiovascular complications of diabetes.

This study was performed to investigate the enhancement of UV-protection activities and skin-whitening effects from Angelica gigas Nakai extracts on ultra high pressure extraction process. Extraction at $60^{\circ}C$ treated by ultra high pressure for 15 minute and associated with ultrasofication (HPE15) was showed more than double yield, compare conventional extraction, as 12.24% (w/w) from A. gigas. Extracts of HPE15 reduced expression of MMP-1 on UV-irradiated CCD-986sk cells as 122.2% and revealed high inhibitory potency on tyrosinase as 69.4% by adding samples. Extracts of HPE15 from A. gigas showed strong inhibition effect on melanin production test by Clone M-3 cells as 82.4% by adding extracts. From the preliminary observations, we considered that the extracts from A. gigas could be potent natural materials for skin-whitening agent, and could be used as a potential anti-aging agent for the photo-damaged skin.

This study aimed to examine the operation of the Home Economics education courses in the graduate schools of education, and to find out how graduate students perceive them. Data were collected with the use of handbooks issued by 11 graduate schools of education located in Seoul, and through telephone conversations with the administrative staff. To determine how graduate students majoring in Home Economics perceive their Home Economics courses, a survey was conducted among the graduate students in 10 graduate schools of education, and a total of 131 accomplished questionnaires were used for data analysis. The results of the study are as follows. First, all 11 graduate schools aimed to retrain their teachers, enhance their professionalism, and produce home economics education experts. The Home Economics Education courses come in two strands; a teacher's course and a major course. Most of the schools require a total of 30 credits. All Schools lack professors. Only 3 graduate schools have a home Economics Department in the College of Education. All graduate schools are offering a teacher's course based on a teacher's certification system. In a major course, Home Economics education has the largest number of subjects, with Clothing and Textiles and Food and Nutrition being given greater emphasis, and Consumer Economics, Home Economics Management, Child Care, and Family and Housing Studies being given less emphasis. Second, they mostly regard the graduate school of education as producer of experts, followed by producers of teachers and teacher re-trainers. Those who were majoring in Home Economics Education in college, and the teachers, are more interested in teacher re-training, while the non-teachers and those who were not majoring in Home Economics Education are more interested in producing teachers. They are less satisfied with the operation of the graduate school of education. But they are generally satisfied with the Home Economics Education course. Graduate students registered the lowest satisfaction with a major course, especially experimental subjects. For a teacher's course, the graduate students who are not teachers exhibited higher satisfaction, whereas the teachers showed lower satisfaction. But teachers registered more satisfaction with the practical use of major subjects in the educational field, thinking that their major was a big help in their work at a school. As for what has to be improved with regard to the Home Economics Education course, many cited the necessity of securing a good faculty and expanding the major subjects.

Background : Many diseases like lung cancer and tuberculosis can involve cervical lymph node. Fine needle aspiration cytology(FNAC) was known as a useful screening test for the evaluation of enlarged lymph node. But the usefulness and limitations of FNAC according to disease category or physical characteristics of lymph node were not yet fully established. Methods : Retrospective analysis of three hundred forty two adult patients who performed FNAC due to enlarged cervical lymph nodes at the Seoul Municipal Boramae Hospital during the period from January 1999 to December 2002 and final diagnosis could be made by surgical biopsy, microbiology or clinical observation. Results : Among the 342 cases, 176(51.5 %) were finally diagnosed as benign nature ncluding reactive hyperplasia, Kikuchi's disease and acute suppuration. Eighty eight(25.7 %) were diagnosed as tuberculous lymphadenitis, 66(19.3 %) as metastasis, and 12(3.5 %) as lymphoma. Tuberculosis, metastasis, and lymphoma all showed significantly larger diameter, longer duration of lymph node enlargement. There were higher frequency of supraclavicular involvement in the cases of tuberculosis and metastasis. The overall diagnostic sensitivity of FNAC was 88.0 %, and 88.6 % in benign nature lesion, 77.3 % in tuberculosis, 90.1% in metastasis and 58.3 % in lymphoma. The diagnosis of tuberculosis was made by FNAC in 68 cases (77.3 %) among 88 cases. Lung cancer(43.9 percent) was most frequent cause of cervical lymph node metastasis. Diagnostic sensitivity of FNAC was significantly lower in the supraclavicular than other cervical lymph node(80 % vs. 91.3 %) and not correlated with disease nature, node size or number. Conclusion : Though FNAC was a reliable screening test for enlarged cervical lymph node enlargement, the diagnostic sensitivity was low in the case of lymphoma or when the enlarged lymph node was located at the supraclavicular area.
