  • The optimum planting date, plant spacing, and harvest time for production of small-sized sweetpotato was evaluated in 2003 to 2004 at the Mokpo Experiment Station. Small-sized sweetpotato is important as snack food in Korea. Optimum planting date and plant spacing were with plastic mulch, and mid-April and $75{\times}15{\sim}20cm$ respectively, mid-June and $75{\times}15cm$ respectively without plastic mulch. Storage root yield decreased with early harvest, but the ratio of small-sized sweetpotato was higher in plots harvested after 100 days of planting (DAP) than that of 80 or 120 DAP. Considerable differences in storage root yield was noted with planting dates and plant spacings, but the use of plastic mulch resulted to smaller yield variations in plots, harvested in mid-April. Planting in mid-April and harvesting after 100 DAP increased income by about $32{\sim}61%$ compared with plantings mid-May.

  • Comparing with film-screen system, flat-panel detector has extensive dynamic range. Focusing flat-panel detector, whole body human phantom PBU-50 (Kyoto, kagaku, Japan) was used to perform comparative study of the estimate of image quality and exposure dose. the exposure condition was 81kV and 20mAs, which is used for Abdomen supine exam in clinical area. As a result of the kV change of the interpreted medical image which has over 30dB of PSNR value, the value of DAP shows the difference of 19.6 times. Moreover, the result of comparing kV change with effective dose of ICRP 103 shows that stochastic effect was increased by over exposure. Therefore, it is significantly necessary that digital radiation technical chart will be used to obtain high quality image and make the standard of dose by educating radio-technologist continually.

  • This study was performed to evaluate cardiopulmonary depressant effects of enflurane (1.0 vol%) combined with propofol(0.25 mg/kg/min) compared with enflurane inhalation, and propofol infusion, respectively, in 18 healthy dogs premedicated with acepromazine and atropine. After bolus injection of propofol 5 mg/kg for induction and tracheal intubation, they were randomly assigned to 3 groups: propofol 0.5 mg/kg/min infusion (Group I, n=6), enflurane 2.5 vol% (Group II, n=6) and enflurane 1.0 vol% combined with propofol 0.25 mg/kg/min (Group III, n=6). Mean arterial Pressure (MAP), systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) were depressed significantly in all groups, especially in Group II. MAP, SAP and DAP values of Group IIIwere higher than those of Group II, but lower than those of Group I. The changes of PaO$_2$, Pa$CO_2$and pHa were similar in all groups. Respiration rates were decreased in all groups 5 minutes after induction but maintained in normal range. Those of Group I were less depressant than those of Group II and Group III. Concentrations of $Na^+ and Cl^-$ were increased and those of $K^+$ were decreased in all groups, but their values were quitely similar. Heart rate was changed in small range and the value of Group I was higher than those of Group II and Group III. Body temperature was decreased significantly in all groups. Adverse effects like as muscle rigidity, nausea or vomiting and shivering were not appeared and apnea at induction was occured 6 dogs. From the these results, enflurane 1.0 vol% combined with propofol 0.25 mg/kg/min also could be applied for anesthesia in dogs.

  • The interfacial phenomena between intermetallic compounds and Al matrix have been studied at $680^{\circ}C$ for various holding time under argon atmosphere. Model experiments were performed using Fe, Ni and Ti wire to observe the interfacial phenomena. The interfacial phenomena between intermetallic compounds and Al matrix were analysed by optical microscope, SEM and EDX. The results of EDX and XRD showed that the interfacial zones of intermetallic compounds/Al matrix were composed of several intermetallic layers. The reaction layer was varied with holding time and heating temperature. The investigation of interfacial zones in the specimen as a function of heat treatment time at $680^{\circ}C$ indicated that the best heat treatment condition for squeeze casting was $680^{\circ}C$ for 5min.

  • $Pb_{1-x}$ $Cd_{x}$ $I_2$ (x=0.0, 0.2, 0.5, 0.7, 0.9, 1.0) single crystals were grown by using Bridgman method and their structural and optical properties were investigated from the measurement of X-ray diffraction, optical absorption and photoluminescence. As-grown single crystals have hexagonal closed packed layered structure. The values of lattice constant c decrease with increasing composition x. Direct and indirect transition optical energy band gaps are calculated from optical absorption spectra measured at room temperature. They increase exponentially from 2.3eV to 3.2 eV with increasing composition x. The energies of photoluminescence peak due to donor bound exciton measured at 6K increase with increasing composition . However, the peak energies of donor-acceptor pair (DAP) are independent of the optical energy band gaps of $Pb_{1-x}$/$Cd_{x}$ $I_2$ single crystals.

  • The purpose of this study is to reconstruct upper class women's costume of 'Mongol-pung' and 'Goryeo-yang' in a civilization-exchanged period between Mongolia and Korea, for making movie or soap opera costume and historical animation. 'Mongol-pung' was a cultural influence from Mogolia to Korea. For example, sleeveless bi-gap(比甲) and half-sleeved dap-ho(搭忽) were put on by many women at that time. On the basis of old literature, I suggest a 'Mongol-pung' costume as a set of seeran-chulrik(膝欄 terlig), em-broidered bigap, dapho of meat-red color for women. 'Goryeo-yang' was a cultural influence from Korea to Mongolia. Due to old poem of Yuan, 'Short outer Jacket with square neckline, half sleeves, and clear color(方領過腰半臂)' was a representative of 'Goryeo-yang' in Mongolian royal women's costumes. Many women were dressed in it with short inner jacket and wide skirt. In the case of making soap opera costume, the budget of broadcasting station, appearence of nowaday's actor and actress, similarity between old fabric and modern fabric must be considered altogether.

  • The Actinomycete strain KH29 is antagonistic to the multidrug-resistant Acinetobacter baumannii. Based on the diaminopimelic acid (DAP) type, and the morphological and physiological characteristics observed through the use of scanning electron microscopy (SEM), KH29 was confirmed as belonging to the genus Streptomyces. By way of its noted 16S rDNA nucleotide sequences, KH29 was found to have a relationship with Streptomyces cinnamonensis. The production of an antibiotic from this strain was found to be most favorable when cultured with glucose, polypeptone, and yeast extract (PY) medium for 6 days at $27^{\circ}C$. The antibiotic produced was identified, through comparisons with reported spectral data including MS and NMR as a cyclo(L-tryptophanyl-L-tryptophanyl). Cyclo(L-Trp-L-Trp), from the PY cultures of KH29, was seen to be highly effective against 41 of 49 multidrug-resistant Acinetobacter baumannii. Furthermore, cyclo(L-Trp-L-Trp) had antimicrobial activity against Bacillus subtilis, Micrococcus luteus, Staphylococcus aureus, Saccharomyces cerevisiae, Aspergillus niger, and Candida albicans, However, it was ineffective against Streptomyces murinus.

  • Gwa-du(裹肚), name of a garment, appears often from documentary records of Joseon Dynasty. It is assumed as one of the upper garments for men, and according to the record, it was worn as a set with Dan-ryung(團領), Dap-ho(搭胡), Chul-rik(帖裏), Han-sam(汗衫), pants and socks. After the Japanese Invasion of Korea in the 17th century, it changes to a shape of wrapping clothes with straps at four corners, and used to cover the stomach of a corpse like sash. From 16th-17th century, before the Japanese Invasion of Korea, the excavated costume shows a clothing which takes a role of Jegori, longer than Han-sam(汗衫) and shorter than Po(袍). In this study, this clothing is called Gwa-du(裹肚). This study examined the usage and shape of Kwa-du from some documentary records- "朝鮮王朝實錄-The Annals of the Joseon Dynasty", "禮書- Book of Manners", "宮中件記- Googjoonghalkee, recording court goods and commodities lists" and more with actual clothing. Kwa-du is presumed to have changed to men's Jegori So-chang-ui(小氅衣) after 17th century.

  • Rose seed shows low germination percentages (about 20%) because it has a high amount of substances that inhibit germination in the pericarp. We investigated the effect of orientation of achene, the day after pollination (DAP), and cold storage with or without half-cut in achene for the germination percentage in R. rugosa. Germination percentages of intact or half-cut achenes were investigated in a 16-hour photoperiod at $25^{\circ}C$ room on basal MS medium for two weeks. In germination percentage, maximum 100% was measured within one week when half-cut achenes were cultured on an orientation that the embryos facing to the light. Half-cut achenes at 90 DAP were germinated 100% regardless of cold storage. Various LED lights (red, blue, yellow, green, and white) were illuminated over the half-cut achenes to gain the effect of light color. Germination percentage of R. rugosa seeds under blue LED reached the greatest with 90% within one week of culture and these seedlings were the best with a steady growth rate. It is concluded that half-cut achenes would be an effective method to improve seed germination in R. rugosa without stratification or scarification. This system could be applied to breeding studies in rose cultivars.

  • Ten types of farm-made brewing vinegars were collected and four high acetic acid-producing strains (CV1, CV3, CV5, and CV6) were isolated. Among them strain CV1, exhibiting highly alcohol-resistant and acetic acid-producing properties, was selected and its taxonomic properties were investigated by phenotypic (particularly chemotaxonomic) characterization and phylogenetic inference based on 16S rRNA gene sequence analysis. On SM broth agar, cells of strain CV1 were gram-stainingnegative and formed pale white colonies with smooth to rough surfaces. Strain CV1 produced acetate from ethanol and was resistant to up to 8% (v/v) ethanol in LM broth. Strain CV1 had a G+C content of 61.0 mol%, contained meso-DAP as the cell wall amino acid, and possessed Q-10 as the major ubiquinone. A comparison of 16S rRNA gene sequences showed that strain CV1 was most closely related to Gluconacetobacter saccharivorans (≥99.0% identity). In liquid media, the optimum growth conditions for acetic acid production were 30℃ and pH >3.0 and strain CV1 produced 9.3% and 8.4% acetic acids from 10% and 9% alcohol concentrations, respectively.
