Korean local collected strains or varieties of perilla analyzed on their protein and oil content and fatty acids composition in the seed. The strains analyzed were 90 of which grown in the experimental field of Chungbuk Agricultural Research and Extension Services at Cheongwon and Umseong from 2001 to 2002. The seed protein contents of 90 perilla varieties ranged from 19.1% to 29.0% and the average content was 22.8%. There differed by the seed coat color showing 1.9% higher content in light gray than that of dark brown, which may suggest that the seed coat color could be used as a marker gene for breeding high protein varieties. Oil content of medium and late varieties in maturity showed higher as compared to early varieties, and appeared differences by seed coat color, and small seed varieties showed higher seed oil content than in large seed varieties by seed size. Linoleic and linolenic acid content of which major fatty acids in perilla seed were 74.4% in average of tested varieties. Fatty acid composition of perilla varieties were not significantly different by maturity, seed coat color and 1,000 seed weight. Oil content showed high positive correlation, with stearic and linolenic acids and negative correlation with linoleic acid.

This study was conducted to establish the cultural techniques of the puddled-soil drill seeding of race (Oryza sativa L.), which is one of the efficient labor saving cultural methods, in the central part of Korea. Seoanbyeo was seeded at three times from April 10 to May 20 with the 20 day interval in 1994. The number of seedling stands per m2 at each seeding date were 50, 90, 130 and 170. The tillering characteristics, lodging characters, dry matter production, yield components and yield were investigated. The number of days to the maximum tillering stage was reduced at the later seeding date. It was 70, 55 and 25 days in seedings on April 10, April 30 and May 20, respectively. The critical effective tillering stage was also shortened at the delayed seeding. The higher the number of seedling stands was, the higher number of tillers, the shorter duration to the maximum tillering stage and the earlier critical effective tillering stage were resulted. The number of tillers was higher at the earlier seeding date. The number of tillers was increased in the order of 50, 90, 130 and 170 seedling stands per m2. The ratios of effective tillers were 53, 61 and 63% at seeding on April 10, April 30 and May 20, respectively. The ratios were not significantly different at April 10. But the ratios in seeding on April 30 and May 20 were reduced as the number of seedling stands was increased. The weight of stem base related to lodging was the highest with 2.01g/10 plants in the optimum seeding on April 30, while it was 1.59g/10 plants in the late seeding on May 20. It was also decreased as the number of seedling stands was increased. The dry weights at 30 days before the heading stage were increased at the later seeding, while the dry weight at the heading stage was the highest at seeding on April 30 which is considered as the adequate seeding time. The dry weights at 30 days before the heading stage were increased as the number of seedling stands was increased and they were increased up to 130 seedling stands per m2 at the heading stage. The length of panicle exsertion was shortened at the later seeding. The length of panicle exsertion was increased up to 130 seedling stands. but it was shorter at 170 seedling stands. The heading dates were later at seeding on April 30 and May 20 than at seeding on April 10. They were not remarkedly different among seeding dates at 50 seedling stands, it was earlier at the higher number of seedling stands over 90. The number of spikelets per panicle was decreased at the higher number of seedling stands. The ratio of ripened grains was higher at earlier seeding than at later seeding. It was not significantly different among the number of seedling stands at the same seeding time. Yields at seeding on April 30, April 10 and May 20 were 644, 624 and 551kg/10a, respectively. The seeding on April 30, the optimum seeding time, resulted the highest yield. Rice quality was decreased due to the increase of the green kerneled rice as the seeding date was delayed.

This experiment was carried out to obtain indispensable information to establish comprehensive cultural method of rice in direct seeding on dry paddy at Chungbuk Agricultural Research and Extension Services. Effect of seeding date on dry matter production, yield components and yield were studied. Seeding on May 5 ensured the highest maximum number of tillers, while transplanting on May 20 gave the highest rate of effective tillers. Number of effective tillers was greater in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. Lengths of upper three leaves were increased at later seeding, but leaf width was not affected by seeding date. Ratio of leaf blade weight was higher in earlier seeding during 30 days before heading but was higher in later seeding during 30 days after seeding, and was higher in the order of Hwajinbyeo, Hwaseongbyeo, Daekwanbyeo. CGR, RGR and NAR were not significantly different among seeding dates during 30 days before heading, but were lower in later seeding during 30 days after seeding. LAR was not affected by seeding date during 30 days before heading, but was higher at seeding on May 5 in heading date and during 30 days after heading. Dry weight of leaf blade, leaf sheath and culm, ear and total biomass during 30 days before heading and heading were highest in May 5 seeding. Daekwanbyeo and Hwaseongbyeo in May 5 seeding and Hwajinbyeo in April 20 seeding brought the highest yield with greater number of spikelets, higher ripening ratio and greater 1,000 grain weight, and harvest index and grain/straw ratio were Increased at earlier seeding. There were significantly positive correlations between number of panicles per m2 and LAI at 30 days before heading and heading, dry matter weight of leaf blade and total mass at heading. On the other hand, there were significantly negative correlations between seeding date and ripened grain ratio. 1,000 grain weight and yield, and between 1,000 grain weight and leaf length of 2nd, respectively.

Background: Pulmonary paragonimiasis is caused by consumption of raw or improperlycooked crustacea infected with the laval stage (metacercaria) of Paragonimus westermani. The most characteristic symptoms were rust-colored sputum and cough. Paragonimiasis causes pleural thickening or effusion in 48% of the patients. Pleuro-pulmonary paragonimiasis can be easily overlooked by physicians who do not suspect this disease in the differential diagnosis. Method: We compared the outcomes of 11 patients with paragonimus empyema managed either through thoracotomy or pig-tail catheter drain. These patients were confirmed by food history, clinical and radiological findings, and laboratory data. Results: The male and female ratio was 1.75 : 1, and mean age was 40.0 ± 13.5 years. AII patients had pulmonary symptoms such as cough or chest pain. Serum-ELISA for paragonimiasis were all positive (mean titer was 0.57). AII patients had pleural effusion in radiological findings( 2 patients had bilateral pleural effusion). All patients received praziquantel (75 ㎎/㎏/day for 3days). Two patients were treated with thoracotomy and nine patients were treated with pig-tail drain. Hospital stay were 14.5 days in thoracotomy group and 5.6 days in pig-tail group respectively, Conclusion: Compared to the conventional thoracotomy grouP, the patients with paragonimus empyema who received pig-tail catheters had a significantly-decreased period of drain in situ, were clinically improved earlier, and were discharged earlier.
