  • We have previously obtained a representative isolate KU101 of the predominant Penicillium species from rice under indoor storage conditions. In this study we attempted to characterize isolate KU101 using its morphological and molecular characteristics. When the micro- and macroscopic characteristics of isolate KU101 were compared with the P. islandicum reference isolate KCCM 34763, isolate KU101 was generally identical to those of isolate KCCM 34763, however, isolate KU101 grew faster and produced more orange to red pigments than isolate KCCM 34763. In a molecular-based identification, the nuclear sequence of the ITS1-5.8S-ITS2 region of isolate KU101 was most closely related to that of P. islandicum. Therefore, these results indicated that isolate KU101 from stored rice could be identified as P. islandicum, some isolates of which are known to produce mycotoxins.

  • Nalita wood (Trema orientalis), one of the fastest growing woods in the world, is characterized anatomical, morphological and chemical properties at annual growth ring level in order to investigate as papermaking raw material. The proportion of fibers and vessel was increased with an increase of growth ring (from pith to bark). The fiber length of Nalita was increased with increasing growth ring, and an average fiber length was about 817 um. The average basic density of Nalita was about 0.38 g/cc. The total lignin & holocellulose in Nalita were increased and ash & alcohol-benzene extract decreased from pith to bark. These values were about 23.5 - 24.4 %, 78.1 - 80.1 %, 1.04 - 0.92 % and 2.1 - 1.8 %, respectively. The xylan was the predominant sugar in the hemicellulose of Nalita.

  • The authors made a clinical study of 107 cases of empyema who were treated at Department of Thoracic Surgery of Chungnam National University Hospital during the period of Jan. 1976 through Aug. 1982 and compared the empyema of infant and children with that of adults. Following was the remits: 1. Male was predominant to female with the ratio of 2.5 to 1 and adult to infant was 2.6 to 1. 2. The cardinal symptoms were dyspnea, coughing, chest pain and fever. 3. Positive remit of bacteriological culture study was reported in 57% and the most common causative organism was staphylococcus in infant and childhood, E. coil in adult. 4. Most frequent predisposing factors of thoracic empyema in infant and childhood was pneumonia [53%], and in adult was pulmonary tuberculosis [40%]. 5. Treatment were combined with antibiotics therapy and several surgical procedures for empyema. 24 cases [22.4%] required open thoracotomy. 6. The mortality rate was 7.4% [8/107]. 86 cases [80.4%] were discharged with recovery and improvement.

  • General components and detergency of commercial shampoos have been investigated and the results are summerized in the following. Shampoos were analyzed for surfactants and additives by KS method and surfactants were confirmed by T.L.C. Considerable differences in amounts of non volatiles and surfactants were found. Three of them contain either lanoline or sterols as additives and in the three. propylene glycol was found in their liquid part. It was shown that predominant sufactant was anionic and in all, except one. a little ampholytic surfactant was detected. But, contrary to forecast, in only one a little of non ionic surfactant was detected. Detergency of shampoos was examined using artificially soiled wool muslin. Considerable difference was found, and all shampoos showed higher detergency than a synthetic powder type detergent for textiles. There were no significant correlation between detergency and amount of surfactants or suspending power of detergents.

  • In order to get abundant germplasm for develop- ing new corn varieties, major morphological characteristics of ear were evaluated with a total of 210 Korean indigenous maize lines collected from various parts of Pusan City and Kyungnam Province, Korea. The ear shape of Korean indigenous maize was mainly cone type or similar to cone type. Cylinder type or similar to cylinder type of corn was collected from the north-west mountainous. region of Kyungnam Province, whereas cone type or similar to cone type was collected from the plain region. In the kernel colors of each ear, ears with mono colored kernels were 55.7% of the total, and ears with two to four mixed colors were 44.3%. Among the mono colored ears, brown was the most abundant at 16.8%. There was an average of 12∼14 rows per ear. Kernal rows per ear varied from 8∼20. Waxy corn was predominant at 67.2%, mixed corn with waxy kernel and common kernel at 11.0%, and common corn at 21.8%.

  • The purpose of this study was to classify the cultural traits of Korean pilots who worked in two airlines in Korea. This study measured the typology of preferring value(horizontal-collectivism, horizontal-individualism, vertical-collectivism, vertical-individualism) with thirty two items developed by Triandis(1995), and analysis based on the target of 135 samples using SPSS 8.0. The result of this study shows that horizontal-collectivism were to predominant overall. It was also founding the captain had the collectivism oriented behavior, and the first officer had the individualism oriented behavior. Another finding of this study is that vertical oriented behavior were majority among the former military trained pilots, and horizontal oriented behavior were majority among the civilian trained pilots.

  • The injection molding process is a predominant method for producing plastic parts. In order to maximize productivity and molding quality in a injection mold, it is important that each cavity in a multi-cavity injection mold is identical. This requires that cavity dimensions should be identical and delivery system of melt to each cavity have to be the same. Despite the geometrically balanced layout in multi-cavity injection mold more than 4 cavities, it has been observed that the filling in each cavity results in imbalances. Most of cases, this phenomenon of filling imbalances have a bad effect on dimension accuracy, warpage, molding appearance and strength of molding parts. In this study, experiment were conducted to investigate the effect of filling imbalances on the molding quality(surface gloss, shrinkage, tensile strength) in the multy-cavity injection mold.

  • German furniture design had been downward in trend after Bauhaus closed and through the War. Meanwhile Italy emerged as a center in furniture industry after the Second World War. After the Unification in 1989, however, German furniture still play predominant role in the world since they have their own unique quality and territory. This study explores the significance of German furniture design by three different eras-Post-war recession (1946-1965), Arising times (1966-1989), Contemporary (1990-2005)-and categorized the major characteristics are summarized as in the below. First, function oriented design Second, pursuing perfection of technology Third, simplicity and purity of design.

  • The flavin-containing monooxygenases (FMOs) (EC 1.14. 13.8) are NADPH-dependent flavoenzymes that catalyze oxidation of soft nucleophilic heteroatom centers in a range of structurally diverse compounds including foods, drugs, pesticides, and other xenobiotics. In humans, FMOl appears to be the predominant form expressed in human fetal liver. cDNA-expressed human FMO and human liver microsomal FMO have been observed to N- and S-oxy-genate nucleophilic nitrogen- and sulfur-containing drugs and chemicals, respectively. In the present study, FMOl can be expressed in the baculovirus expression vector system at level of 2.68 nmol FMOl/mg of membrane protein. This isoform was examined for its capacity to metabolize methimazole to its S-oxide using thiocholine assay. Kinetic studies of its S-oxide by recombinant human FMO1 result in Km of 7.66 $\mu$M and Vmax of 17.79 nmol/min/mg protein.

  • Recently, there are widely needs of small scale electrostatic precipitator(ESP) in machine shop and other factories. Since the space of such factories is limited, the improvement of collection efficiency is predominant subject. In this study, we examine the influence of distribution of wind velocity and oil mist concentration inside the ESP in order to improve the performance of the ESP. The distribution of wind velocity and mist concentration is measured respectively in a cross-sectional plane of the ESP. The former is controlled by using a louver which is placed in front of an ionizer and the latter is controlled by lengthening the pipe of entrance of the ESP in order to have plenty of time that mist is dispersed evenly. It is shown that the uniformity of distribution of wind velocity and mist concentration inside the ESP can be getting by adopting a louver with proper shape and lengthening the pipe of entrance and is also contributed to collection efficiency considerably.
