  • This study aims at establishing a sizing system required for producing ready-made clothes which can fit the body shape of disabled men using wheelchair. It measured the bodies of 178 adult men using wheelchair and compared the sizing system of German adult men using wheelchair (1984) with KS system(KS K0050, 2004) in order to establish standards of the sizing system. AS a result, in terms of classification of body shapes, KS system cover more types of disabled men's body shapes and especially, A types (Drop 15.6) showed the widest coverage with 32%. In classification of heights, the widest range of height was 170 cm, and Korean men's four sizes between 158 cm and 176 cm covers 88.2% of disabled men's body shape. For chest size, 91.1% of disabled men's chest sizes were included in seven sizes, which are 4 cm intervals between 88 cm and 112 cm with 100 cm standard. In consideration of the ranges of height and chest, the general sizes (A types; 11 sizes, B types; 3 sizes, Y types; 5 sizes) are selected to present the standardized measurements. Basic parts of the upper garment sizing system for disabled men using wheelchair were height-chest-waist size.

  • This study investigates the construction management selection methods for fair competition within the construction management market by analyzing the current status of domestic construction management, the 2010 publication on the status of construction management, and the construction management evaluation criteria. Also, the 2009 publication of top CM service establishments, the average proportion of tender for 120 CM services from 2002 to 2010, and six assessment results which are open to the parties directly involved were statistically analyzed to review the adequacy of the evaluation criteria. This analysis shows that the evaluation criteria for the CM service impedes the development of the construction management industry and companies, since the criteria are decided by the service payment, and the technical skills assessed by technical proposals have no ties with contract prices. Therefore, this study proposes an improvement of the selection methods in accordance with the project characteristics and the technical requirements. However, more research is still needed to derive a detailed classification method of the technical requirement, the owner's evaluation criteria selection, and the preparation of an institutional foundation for the construction manager's post-evaluation.

  • Corrosion of brass coated steel cords in the acetonitrile solution of sulfenamide derivatives, N-Cyclohexylbenzothiazole-2-sulfenamide (CBTS), N,N'-Dicyclohexylbenzothiazole-2-sulfenamide (DCBS), N-tert-Butylbenzothiazole-2-sulfenamide (TBBS), N-tert-Amylbenzothiazole-2-sulfenamide (TABS), and N-Oxydiethylbenzothiazole-2-sulfenamide (OBTS) was investigated by potentiostatic anodic and cathodic polarization (Tafel plot), DC polarization resistance, and AC impedance measurements. The corrosion current densities and rates are 1.236 ${\mu}A /cm^2$ and 0.655 MPY for CBTS; 1.881 ${\mu}A/cm^2$ and 0.988 MPY for DCBS; 2.367 ${\mu}A/cm^2$ and 1.257 MPY for TBBS; 3.398 ${\mu}A /cm^2$ and 1.809 MPY for TABS, respectively. OBTS among derivatives under study shows the lowest corrosion density (0.546 ${\mu}A /cm^2$) and the slowest corrosion rate (0.288 MPY). Also, the charge transfer resistances and the double layer capacitances are 275.21 $k{\Omega}{\cdot}cm^2$ and 7.0 ${\mu}F{cdot}cm^{-2}$ for CBTS; 14.24 ${\mu}F{\cdot}cm^2$ and 26 ${\mu}F{\cdot}cm^{-2}$ for DCBS; 54.15 $k{\Omega}{\cdot}cm^2$ and 26 ${\mu}F{\cdot}cm^{-2}$ for TBBS; 0.96$k{\Omega}{\cdot}cm^2$ and 83 ${\mu}F{\cdot}cm^{-2}$ for TABS, respectively. The weaker the electron donating inductive effect of derivatives is and the smaller the effect of steric hindrance is, the more the corrosion of brass coated steel cords in the acetonitrile solution of sulfenamide derivatives is prevented. The above results agree with that observed in the field of tire industry.

  • This study develops 1/2 dress forms for draping. This study investigated the production status of domestic and foreign products in order to model their shape using CLO 3D. In addition, it developed torso-type and torso-crotch-type products that allowed for draping using a 3D printer. This study analyzed shape and size compared to developed ones after referring to the Size Korea 7th Survey data as well as seven domestic and foreign company websites. The results are follows. First, an investigation of the production status of the products for the size of most of the domestic ones (except K-4) indicated that the waist circumference was slimmer than Size Korea. Bust, waist, and hip circumferences ranged from 42.0 cm, 32.0 cm, and 45.0 cm - 49.0 cm, respectively, in Chinese products; 42.0 cm - 43.0 cm, 30.5 cm - 31.5 cm, and 46.0 cm - 46.5 cm in Japanese products; 43.0 cm, 35.0cm, and 46.5 cm in American products (Japanese body shape applied). Second, an avatar was produced on a 3D software with the average size of 20-24year-old women, and its file modified as a dress form for 3D printing with PLA filament to produce dress forms for draping, workable with pins, using quilting cotton and cotton cloth. Third, the comparisons of the form and flattening between the developed dress forms and the selling ones indicated that flattening was bigger in the waist part of the former than the latter. The waist is produced too slim in the existing dress forms; therefore, it is necessary to correct the waist circumference. Unlike existing dress forms, the developed ones were produced in proximity to the average size of 20-24 year-old women in the Size Korea 7th Survey.

  • For the effective use of red seabream, the texture between red seabream muscles cultured by feeding and starving were compared. Moisture and crude lipid contents of red seabream muscle cultured by starving (RCS) were 72.7% and 3.7%, respectively, which was 3% higher in the moisture compared to that of red seabream muscle cultured by feeding (RCF), while 3% lower in the crude lipid. The hardness of RCS was $0.93\;kg/cm^2$, which was higher than that ($0.47\;kg/cm^2$) of RCF. No differences in total collagen content, acetic acid-solublized collagen content, its thermal denaturation temperature and SDS-PAGE patterns between RCS and RCF were found. The results suggested that the difference in muscle texture between RCS and RCF was probably due to the difference of lipid content.

  • Molybdenum silicide films have been prepared by sputtering from a single composite MoS$i_2$ source on both P, B$F_2$respectively implanted (5${\times}10^{15}ions/cm^2$ single crystal and P implanted (5${\times}10^{15}ions/cm^2$) polycrystalline silicon substrates followed by rapid thermal annealing in the ambient of argon. The heat treatment temperatures have been varied in the range of 600-l20$0^{\circ}C$ for 20 seconds. The properties of Mo-silicide and the diffusion behaviors of dopant after the heat treatment are investigated using X-ray diffraction, scanning electron microscopy(SEM) , secondary ions mass spectrometry(SIMS), four-point probe and $\alpha-step.$ Annealing at 80$0^{\circ}C$ or higher resulted in conversion of the amorphous phase into predominantly MoS$i_2$and a lower sheet resistance. There was no significant out-diffusion of dopants from both single crystal and polycrystalline silicon substrate into molybdenum silicide layers during annealing.

  • Total 418 Yellow Croaker Larimichthys polyactis were examined and the range of total length (TL) was 12.0~27.5 cm and average total length was 19.6 cm. The most important prey component in the diets of L. polyactis was Pisces that constituted 46.5% in %IRI (Index of relative importance). Euphausiacea was the second largest prey component. The result of analysis in ontogenetic and seasonal changes significantly exhibited. The proportion of Pisces increased as increasing body size, whereas the consumption of Macrura decreased gradually. The diets also were different among seasons, with the difference particularly being evident between warm (summer and autumn) and cold (winter and spring) seasons. Permutational multivariate analysis of variance (PERMANOVA) revealed significant dietary differences by seasons (P=0.001).

  • Domestic CM market has continued to grow since the enactment of CM policies in 1996. In addition, future CM market is forecasted to have potential high growth. Therefore, it is necessary to apply various CM business models reflecting the owner's requirements and characteristics in order to improve in the CM industry and to strengthen the competitiveness in the overseas construction market. In this context, the purpose of this study is to suggest strategies of various CM applications based on comparison of 4 cases analyzed by 'business weight' and 'business depth' in terms of business function as well as by the types of 'CM market' and 'CM practice'. Result of this comparative analysis shows that each case presents differences in terms of type, business weight, and business depth of CM practice. However, domestic public CM services are currently being challenged to strengthen capability throughout the project life-cycle against the limitation of government's CM policies focused on the construction supervision. In order to address this problem, this study proposes the strategies of various CM applciations from several different perspectives

  • Knitted fabric using acrylic/wool blended yarn (A/W) is increasingly used in the knit industry; subsequently, research on knitted fabric using A/W has increased. This study presents an scientific database from evaluating physical properties of $1{\times}1$ rib stitch using A/W. In this study,$1{\times}1$ rib stitch using A/W were made at various knitting tensions (dial no. 2-6) and the number (4-6) of ply yarn. The physical properties of $1{\times}1$ rib stitch using A/W were measured and analyzed. The density was in the range 5.5-6.4 wales/cm and 4.0-5.6 courses/cm, respectively. The density increased when less plying yarns and more knitting tension were added during knitting. The thickness was in the range of 1.592-2.362 mm and the tensile strength was in the range 32.75-53.63 Kgf/mm. The burst strength was in the range 107.8-139.2 $N/cm^2$. Thickness, tensile strength, and burst strength increased as the number of ply yarn and the knitting tension increased. The elongation and the recovery extension rate were in the range 102.29-112.13% and 96.4-97.7%, respectively. The heat retention rate was in the range 59.3-65.1%. There was no difference of the elongation and the recovery extension rate and the heat retention rate by the knitting tension and the number of the ply yarn. The permeability was in the range 170.5-396.3 $cm^3/cm^2/sec$. Air permeability decreased as the number of ply yarn and the knitting tension increased. The pilling properties were excellent for all $1{\times}1$ rib stitches.

  • The feeding habits of Lateolabrax japonicus were studied based on an examination of the stomach contents of 344 specimens collected monthly from January to December, 2005 in coastal waters off Dolsan-do, Yeosu. The standard length (SL) of specimens ranged in 8.7~52.8 cm. L. japonicus is a piscivore that consumes mainly teleosts such as Engraulis japonicus, Trachurus japonicus, and Acanthogobius flavimanus. Its diet also includes Macrura, Amphipoda, Cephalopoda, Polychaeta, Mysidacea, and Branchyura. Small individuals (<25 cm SL) consume mainly Amphipoda and Macrura. The proportion of these prey items decreases with increasing fish size, and this decrease paralleled the increased fish consumption.
