  • Five free-living nematode species belonging to the order of Rhabditida are described for the first time in Korea. Two unrecorded species of Rhabditidae, Cruznema tripartitum (Linston, 1906) Zullini, 1982, and Poikilolaimus oxycerca de Man, 1895, and one species of Peloderidae, Pelodera strongyloides Schneider, 1860, were collected in Korea. C. tripartitum has nine pairs of genital papillae arranged in 2+2+1+4 differently from similar species of C. scarabaeum which has ten genital papillae arranged in 2+1+4+3. Poikilolaimus oxycerca has shorter tail (shorter than anal body diameter) compared to similar species of P. regenfussi which has longer tail(longer than anal body diameter). Pelodera strongyloides has shorter tail(1-1.5 times anal body diameters long) than P. punctata (4 anal body diameters long). Two unrecorded species of Panagrolaimidae, Panagrolaimus apicatus Schuurmans Stekhoven & Teunissen, 1938 and Panagrolaimus rigidus (Schneider, 1866) Thorne, 1937 were collected in Korea. P. apicatus has rounded and lower lip compared to similar species, P. margaretae Massey, 1964 which has finely pointed lip. P. rigidus has slender tail and lips rounded and flat barely separated when compared to similar species, P. subelongatus(Cobb, 1914) Thorne, 1937 which has plumper tail and lips are well separated.

  • In order to investigate the effectiveness of Osmose process for the practical treatment of wood this study has been made using water soluble preservatives such as Malenit and chromated zinc chloride. The results obtained in this investigation are as follows: 1. The penetration of Malenit in sapwood has been observed deeper than that of chromated zinc chloride for all species tested in this investigation. 2. The penetration of preservatives applied in soft wood, ie. Pinus densiflora and Larix leptolepis has been observed better results than that of hard wood, i.e., Quercus accutissima and Carpinus laxiflora. 3. The longer stack covering, despite of preservatives applied and size of wood tested, has given better penetration for all species tested, and the fastest diffusion has been occured in 15 days from they day started. Following after 15 days diffusion had gradualy become slower. 4. The length of time needed for effective penetration has taken 45 days for all species tested, reaching twenty millimeters (20mm) in depth in case of Malnit, that means also more than 50% of penetration into sapwood portion. However it has taken 45 days fer Pinus densiflora and Larix leptolepis, reaching fifteen millimeters (15mm) and 60 days for Quercus accutissima and Carpinus laxiflora, reaching same fifteen millimeters in case of chromated zinc chloride, that means also less than 50% (except 50% for Larix) of penetration into sapwood portion. 5. Deeper penetration of preservatives from the wood surface has been observed in the larger wood than the smaller wood for all species tested, although the penetration ratio between the width of sapwood and the length penetrated has been observed smaller in larger wood than smaller wood. 6. The relation between moisture content of wood and the penetration of preservatives into wood tested has shown the linear regression, that is, the more moisture content brought the deeper penetration. 7. Following the result obtained at this investigation osmose process with Malenit applied has indicated as a useable process for the none pressure treatment of wood.

  • Objective : Based on the immunological dysfunction in RA and the immunological feature of Clematis mandshurica Maxim. herbal acupuncture solution (CM-HAS), this study examined whether subcutaneous (s.c.) administration of CM-HAS has anti-inflammatory effects on adjuvant arthritis (AA) in the rat. Methods : Complete Freund's adjuvant was used to induce AA in rats. Secondary paw swelling of AA rats was measured, and polyarthritis index was scored. The administration of CM-HAS (2, 5, 10 mg/kg) to the Sinsu-hyul (BL 23) acupuncture point subcutaneously (s.c.) inhibited the inflammatory response and restored the weight of body and immune organs of AA rats. In this study. inhibitory effect of CM-HAS on cyclooxygenase-2 (COX-2) was evaluated. The plant material selected for this study has been used in Korean medicine for the treatment of various diseases that are considered as inflammatory in nature, e.g. asthma, arthritis, rheumatism, fever, edema, infections, snakebite and related inflammatory diseases. Results : There were significant secondary inflammatory reactions in AA rats, accompanied with the simultaneous decrease of body and immune organs weight. The administration of CM-HAS (2, 5, 10 mg/kg, s.c.) improved the above changes significantly. CM-HAS showed inhibitory activity against COX-2, which supports their traditional uses. In this study, aspirin and indomethacin were used to contrast with CM-HAS as the COX-2 inhibitors. Conclusion: The findings of this study may explain at least in part why CM-HAS has been traditionally used for the treatment of inflammatory conditions in traditional Korean and Chinese medicine.

  • The major purpose of this paper is to examine two closely related issues. An attempt is made here to examine internationally high land price in Korea from the perspectives of market fundamentals (MF) and bubble theory, respectively. Another theoretical issue, whether land speculation can result in market failure, is also examined. It has been concluded that the primary causes for the rapid increases in land prices in Korea, could be found in the perspective of MF. (1) The financial intermediaries has been controlled by the government since 1960s. Real Interest rates in the commercial banks has been controlled at the level of zero or sometimes negative; scarce financial resources has been rationed by the government. The governmental control of the bands has also resirained the development of securities market. Money, which can not find the appropri opportunity for saving in financial market, moves to land market. (2) Socially created land value, based on rapid economic gorwth and big public investment, has been appropriated mainly by the private: The effective tax rate of land holding tax has been under 0.02 percent; Real Estate Capital Galns Tax has, in fact, affected few persons, mainly because examptions and preferential taxation have been widely permitted. (3) The government has ploaced severe limitations on rural-to-urban land conversion, although the demand for urban uses has repidly grown. All factors above caused the cyclical land speculation. This, in turn, created the myth that land prices will inevitably continue to rise. Based on the myth, the growing bubble in land price has been created. This is the secondary reason for high land price relative to income in Korea. It is also shown that it is possible that speculation in land results in market failure because land is fixed in quantity and can be used for production and speculation purposes simultaneously.

  • Most of the software reliability models are based on black box approach and these models consider the entire software system as a single unit. Present day software development process has changed a lot. In present scenario these models may not give better results. To overcome this problem an improved additive model has been proposed in this paper, to estimate the reliability of software with modular structure. Also the concept of imperfect debugging has been also considered. A maximum likelihood estimation technique has been used for estimating the model parameters. Comparison has been made with an existing model. ${\chi}^2$ goodness of fit has been used for model fitting. The proposed model has been validated using real data.
