  • This study was carried out to investigate effects of stock plant management and foliar spray of GA on the flower quality in hydroponically grown chrysanthemum 'Shinma'. In the growth and development as affected by stock plant management, cut flower length, petal number and cut flower weight were the best in the plot of long day and chilling treatment showed 114 cm, 298 and 102 g, respectively. Chlorophyll content(SPAD-value) was the highest in the plot of foliar spray of diluted Molbia(1 : 500). Flower quality according to concentration and spray time of gibberellin showed a different pattern. Cut flower length was the longest in the plot of solution diluted to 1 : 1,000 spraying before flowering at 60 days, petal number was the most in 1 : 500 at 60 days, and cut flower weight was the heaviest in 1 : 2,000 at 60 days, respectively. However, peduncle length was tended to be elongated with foliar spray of gibberellin solution diluted to 1 : 500 or 1 : 1,000 before flowering at 45 days.

  • This experiment was conducted to investigate the effect of soil moisture content on cut flower quality of Gypsophila paniculata L. 'Bristol Fairy' in spring and autumn cultivations. The soil moisture potential (SMP) set point for irrigation was either -3.2 or -10.0kPa in the vegetative growth stage, and -10.0, -31.6, or -79.4kPa after the budding stage. When soil moisture reached at each set SMP point, 10 mm water was drip-irrigated. Tendency of flowering was earlier as SMP set point was lower in both vegetative growth and after budding stages. No other flower characteristics were found among other treatments. In both spring and autumn cultivations, as SMP set point was lower, the low primary branch length and upper internode length were decreased, the stem firmness was increased, and curvature of cut flower stem was decreased. Especially, in autumn, the higher the SMP set point, the higher the low primary branch than the apex, thus the paniculate inflorescence was deeply destroyed. Yield in spring cultivation was not significantly different among treatments, while that in autumn cultivation increased as the lower the SMP value. It is thought that optimal imgation points during vegetative growth and after budding stages to produce high quality cut flowers are -10.0 and -79.4kPa, respectively.

  • This study was carried on paper mulberry bast fibers, which were cut in the length of it's chip by three kinds. And they cooked by sodium hydroxide (NaOH) and ammonium oxalate (AMOX), and pulping process was studied to inquire some properties of hand made papers. The results were as follows. AMOX pulps had $10\~17\%$ higher than NaOH, but amounts of the residual lignin of it's pulps and residual ash were high, and it surely can't be superior. In the freeness of pulps, AMOX pulps were higher than that of NaOH, but they showed tendency to opposite in view of relation of chip's length kinds. For the AMOX pulps, the physical characteristics test results were higher long fiber pulps than short fiber pulps. Specially, in folding endurance long fiber pulps were a very strong. NaOH pulp's physical characteristics test had shown results that were opposite of there of the AMOX pulps, if the length of the fiber is longer, the strengthts generally decreased. To get the optimum fiber's length according to use of paper and pulping method, they must be fractionate chip's length. The long fibers in NaOH pulps affected the paper quality greatly to length of chips.

  • Purpose : To report the 'condylar cut-off sign', a new radiographic sign in knees with discoid lateral meniscus and to report the sensitivity, specificity, positive predictive value and negative predictive value of the sign to elucidate the diagnostic significance of the sign for discoid meniscus. Materials and Methods : Fifty knees with complete discoid lateral meniscus and fifty normal knees formed the basis of this study. All of them were arthroscopically confirmed fer the discoid or normal lateral meniscus. The authors developed a method to measure the length of the medial and lateral condylar were compare and analyzed. Results : Tile average ratio was 0.716 in the discoid meniscus group, and 0.902 in the normal group. The stastistical analysis by the T-test revealed the t-value -11.13(p<0.0001). Stastistical analysis by chi-square test using cut point 0.8, also showed significant difference between the two groups, with $76\%$ sensitivity, $100\%$ specificity, $100\%$ positive predictive predictive value and $81\%$ negative predictive value. The 'condylar cut-off sign' was readily detectable in all cases of discoid lateral meniscus, suggesting that the cut off sign could serve as a simple and reliable radiographic sign fur the diagnosis of discoid meniscus. Conclusion : The condylar cut-off sign on the Tunnel view of simple radiography of the knee can serve as a good sign for the diagnosis of discoid lateral meniscus, with $100\%$ positive predictive value.

  • The Sonication method is widely used with surfactants to suspend individual single walled nanotubes in solution, and it is well known that sonication-induced tube cutting occurs. Recently, it is found out that ultrasonicated nanotubes yield simultaneous separation by tube length and diameter. Nanotubes that have been cut shortest possess the greatest enrichments of large-diameter species. In this study, we cut single walled carbon nanotubes using a ball milling method and find out similar behavior compared to the sonication process Cutting mechanisms are also investigated using continuum approaches.

  • A new hybrid variety of pasqueflower, 'Yeonhong', was derived from an interspecific cross between Pulsatilla davurica and P. koreana at the Jeollanamdo Agricultural Research and Extension Services (JARES) in Naju, Korea. The original cross was performed in 2001, and the 'Yeonhong' hybrid was established in 2003 after two years of selective breeding. 'Yeonhong' is characterized by deep pink flowers and is self-incompatible. The inherent characteristics of the variety are deep yellow anthers, a deep pink stigma, six petals, and green leaf color. 'Yeonhong' blooms twice a year. The agronomic characteristics of the variety are 26.5 flowers per plant, 58.6 cm in flower height, 46.8 cm in cut flower length, 11.5 cm in bract width, and 34.4 cm in leaf length. Flower characteristics include 8.4 days of longevity for cut flowers and 34 days of longevity for bracts. The new variety is suitable for use as a cut flower.

  • In this study, 3-D analyses were conducted while taking every construction stage into account. Then 2-D analyses were conducted which yield the same results with the 3-D results. The crown settlement normalized by the ultimate value was compared during the process to overcome the discrepancy caused by different dimensions. When a bench or a core is left uncut to give extra support to the face and eventually the whole excavation boundary, this extra supporting effect also has to be included in the analysis. In this study, this effect is also implemented in terms of the load distribution factor. When the length of the bench is very short compared to the diameter of the tunnel in such cases as in short bench cut or in mini-bench cut, the supporting effect of the face does not disappear even after the bench is completely excavated and supported since the face is still too close to the point of interest. The 4th load distribution factor was defined to stand for the advance of the face after the completion of the excavation cycle. The 4th load distribution factor turned out to be very useful in determining the load distribution factors when a tunnel is excavated by bench cut with various bench lengths under different initial conditions.

  • This study was conducted to control unseasonable flowering in a standard chrysanthemum 'Baekma' bred in Korea by 2-chloroethylphosphonic acid (ethephon) and night temperature (NT) through suppression of the transition from a vegetative to a reproductive stage under long day length caused by high NT in summer season. Ethephon was applied either once or twice at a concentration of 0, 200, 400, or $800mg{\cdot}L^{-1}$. The NT within controlled mini-plastic houses was maintained at 13, 17, or $21^{\circ}C$. The NT at $13^{\circ}C$ showed the greatest inhibiting effect of unseasonable flowering among all NTs regardless of various combinations of ethephon concentration and frequency. Moreover, the inhibition tendency of unseasonable flowering was distinctly decreased in a NT-dependant manner. Higher NTs reduced cut flower length and number of leaves, but increased the number of young leaves attached to top part of the flower. Higher ethephon concentrations and lower NTs increased cut flower length and the fresh weight of total, stem, and leaves due to the extension of vegetative growth period. Thus, if it is difficult to control the NT below $21^{\circ}C$ in greenhouses in the summer season, we recommended to spray more than $200mg{\cdot}L^{-1}$ ethephon once after planting to suppress unseasonable flowering and to ensure sufficient length of cut flowers.

  • Objective: The objective of this study was to identify polymorphism in olfactomedin like 3 (OLFML3) gene, and association analysis with meat quality, carcass characteristics, retail meat cut, and fatty acid composition in sheep, and expression quantification of OLFML3 gene in phenotypically divergent sheep. Methods: A total of 328 rams at the age of 10 to 12 months with an average body weight of 26.13 kg were used. A novel polymorphism was identified using high-throughput sequencing in sheep and genotyping of OLFML3 polymorphism was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Among 328 rams, 100 rams representing various sheep genotypes were used for association study and proc general linear model was used to analyse association between genotypes and phenotypic traits. Quantitative real-time polymerase chain reaction (qRT-PCR) was used for the expression analysis of OLFML3 mRNA in phenotypically divergent sheep population. Results: The findings revealed a novel polymorphism in the OLFML3 gene (g.90317673 C>T). The OLFML3 gene revealed three genotypes: CC, CT, and TT. The single nucleotide polymorphism (SNP) was found to be significantly (p<0.05) associated with meat quality traits such as tenderness and cooking loss; carcass characteristics such as carcass length; retail meat cut such as pelvic fat in leg, intramuscular fat in loin and tenderloin, muscle in flank and shank; fatty acids composition such as tridecanoic acid (C13:0), palmitoleic acid (C16:1), heptadecanoic acid (C17:0), ginkgolic acid (C17:1), linolenic acid (C18:3n3), arachidic acid (C20:0), eicosenoic acid (C20:1), arachidonic acid (C20:4n6), heneicosylic acid (C21:0), and nervonic acid (C24:1). The TT genotype was associated with higher level of meat quality, carcass characteristics, retail meat cut, and some fatty acids composition. However, the mRNA expression analysis was not different among genotypes. Conclusion: The OLFML3 gene could be a potential putative candidate for selecting higher quality sheep meat, carcass characteristics, retail meat cuts, and fatty acid composition in sheep.
