The present study was conducted to elucidate the relationship between parent's verbal control modes and children's social competency. Two questionanires were developed by the authors for this study. The questionnaire for measuring parent's verbal control modes was composed of 84 and 87 items for mother and father, respectively, which assesses three types of verbal control modes; imperative control position-oriented control and person-oriented control. The questionnaire for measuring children's social competency perceived by mothers was composed of 27 items, which assesses four areas of social competency; initiative sociability responsibility and self-disclosure. the subjects of this study were 436 mothers and their children of fifth and sixth grade in elementary schools located in Seoul. The results of this study were as follows: 1) Parents control their children mostly by position-oriented mode and least by imperative mode. 2) There were significant correlations between father's verbal control mode and children's social competency. children's social competency was related positively to the person-oriented and position-oriented modes but negatively to the imperative mode. The best variables explaining boy's social competency were father's imperative and position-oriented modes whereas that for girl's was position oriented mode. 3) Mother's verbal control mode was not significant in explaining children's social competency. 4) The negative impact of father's imperative mode in combination with the mother's person-oriented mode on the children's social competency was greater than other combinations of father's and mother's verbal control modes.

The result of studying the pathogenicity of Salmonella typhimurium and S enteritidis isolated from domestic animals in Gyeongbuk province were summarized as follows. In Congo-red binding test, S typhimurium had much more rough types than S enteritidis. In colicin production test, 4 strains of S typhimurium were positive but all of S enteritidis were negative. In hemolysin production test, all of S typhimurium and S enteritidis were negative. In Guinea pig serum resistant test, all of S typhimurium and S enteritidis were positive. As a result of pathogenicity test to mice, 54.4% of mice were died. Therefore, S typhimurium and S enteritidis were considered as highly pathogenic. S typhimurium DT104 and S enteritidis PT4 were more pathogenic to mice than other phage types of same serovar. S typhimurium and S enteritidis were considered not so pathogenic for 6-day-old chickens. The recovery rates of Salmonella stains from mice and chickens inoculated were 96.8%, and 54%, respectively. In chickens, proportional to the time from 2 weeks after challenge inoculation, the recovery rates were noticeably decreased.

The purpose of this study was to investigate the effects of mother's neuroticism and parenting stress, and young children's stress on internal and external problem behaviors. The participants of this study consisted of 236 mothers, who had children aged 5-7 in Chungbuk area. Mothers responded to questionnaires and data analyzed using SPSS program(version 12.0) and AMOS program(version 5.0). The results of this study were as follows.: First, a mother's neuroticism, parenting stress, and young children's stress directly influenced on young children's internalizing problem behaviors. The effect of mother's neuroticism on young children's internalizing problem behaviors was mediated by mother's parenting stress and young children's stress. Second, mother's parenting stress influenced young children's externalizing problem behaviors directly, but mother's neuroticism and young children's stress did not. The effect of mother's neuroticism on young children's externalizing problem behaviors was mediated by parenting stress.

Water dispersible ZnS based nanocrystals: ZnS (blue), ZnS:Cu (green) and ZnS:Mn (yellow-orange) were synthesized by capping the surface of the nanocrystals with a mercaptopropionic acid (MPA) molecule. The MPA capped ZnS based nanocrystal powders were characterized by using XRD, HR-TEM, EDXS, FT-IR, and FT-Raman spectroscopy. The optical properties of the colloidal nanocrystals were also measured by UV/Vis and photoluminescence (PL) spectroscopies in aqueous solvents. The PL spectra showed broad emission peaks at 440 nm (ZnS), 510 nm (ZnS:Cu) and 600 nm (ZnS:Mn), with relative PL efficiencies in the range of 4.38% to 7.20% compared to a reference organic dye. The measured average particle sizes from the HR-TEM images were in the range of 4.5 to 5.0 nm. White light emission was obtained by mixing these three nanocrystals at a molar ratio of 20 (ZnS):1 (ZnS:Cu):2 (ZnS:Mn) in water. The measured color coordinate of the white light was (0.31, 0.34) in the CIE chromaticity diagram, and the color temperature was 5527 K.

The purpose of this study was to research grading work according to the targets of women's wear manufacturers in Korea. For the questionnaire, 91 women's wear brands, which were in higher ranking of sales, were selected, and the age groups were separated into 3: 20's, 30's, and 40's & 50's, according to their customers. The graders of each brand were questioned about 20 items for this research. The results of the questionnaire were as follows: 1 The brands for older women manufactured more sizes and cared more about somatotypes fur grading than other brands did. 2. For upper garments on the basis of bust girth, the numbers of dimensional increments were different depending on the age groups: 9 for 20's, 7 for 30's, and 7 for 40's & 50's. 3. For lower garments on the basis of hip girth, the numbers of dimensional increments were different depending on the age groups: 9 for 20's, 6 for 30's, and 5 for 40's & 50's. 4. As a model size of grading, many brands used the smallest size, but the brands for 40's & 50's also used the second size. 5. The parts needed to be corrected after grading were sleeve ease, armhole, shoulder line, neckline, crotch curve, etc. The grading with CAD system had more correction after grading than hand grading.

This study was conducted on 878 retired women in their 50s and 60s across the country using the 7th data from the National Pension Service's KReiS. We used SPSS WIN 18.0, and the analysis results are as follows. First, there were many highly educated people in their 50s or older and those in their 60s and undereducated. Second, families in their 50s had the largest number of members with more than three, while households in their 60s had the largest number of two. Third, both age groups chose themselves and their spouses as responsibilities for preparing for retirement. In addition, more people in their 60s chose the government as their responsibility for preparing for retirement than in their 50s. Both people in their 50s and 60s say they are "not prepared" to prepare for retirement expenses, raising concerns about elderly poverty. Fourth, economic strength, health, and medical care were important for retirement in both age groups as part of their preparations for retirement, and they chose economic strength, health, medical care and job as the things to do in society. Fifth, both people in their 50s and 60s have very low public and private pension subscription rates, requiring special attention from the government and society to their old age. Judging from the above results, both women in their 50s and 60s have retired, but preparations for retirement are very insufficient. Therefore, the government and society need to strengthen the public pension system and create jobs for the elderly.

Since the emergence of a philosophical theory called deconstructivism, intertextuality has been promote the hybrid phenomenon amongst other jenres in arts. Various research efforts in intertextuality, however, have been more focused on the fields of literature and philosophy, rather than of architecture. This study aims to clarify the intertextuality between architectural design, music and literature as the following analysis of James Joyce's Finnegan's Wake, John Cage's music and Bernard Tschumi's early works. Joyce's Garden of Bernard Tschumi's project and some of John Cage's music works had borrowed from Finnegan's Wake, a novel James Joyce. Hence, the commonality between Bernard Tschumi and John Cage can naturally be related through Finnegan's Wake. Also, Finnegan's Wake had been contextualized by Jacques Derrida before it was used as a mediation by Bernard Tschumi. In this viewpoint, the paper will be able to identify the possibility of intertextuality between musical text and architectural one with a medium of literature. Major findings of the study are as follows: First, Finnegan's Wake played a guiding role to deconstruct the existing formalism and to construct a new concept in John Cage's music and Bernard Tschumi's architecture. Second, John Cage's music and Bernard Tschumi's works are included commonness with indeterminacy concepts. Third, the both artists share a drawing concept as found in John Cage's graphic notation of the 1950s and Bernard Tschumi's early architecture where grids, dots, and curves are used in common. As s result, intertextuality could be possible to make sure between others. Like this interdisciplinary research of relationships among different fields will be of great help in constructing creative design methods in architecture. With continuous research attempts, it is hopeful to intertextualize architectural texts with related art fields.

In the upcoming 5-generation mobile communication system, various techniques for improving the power efficiency and spectral efficiency have been proposed. 5G mobile communication system also have been studied a lot of multi-carrier-based modulation techniques like the 4G mobile communication system. In this paper, we analyzed the conventional system structure of the Zero-tail DFT-s-OFDM and UW (Unique Word) -DFT-s-OFDM system based on DFT-s-OFDM system in these techniques. UW and zero are added and used each system, and CP is removed. the result of quality of systems for simulation, OOB(Out of Band) power of Zero-tail DFT-s-OFDM and UW-DFT-s-OFDM use the less time resource as long as CP length, also both systems are reduced about 11dB than DFT-s-OFDM system. In these result, Zero-tail DFT-s-OFDM and UW-DFT-s-OFDM system are more effective than DFT-s-OFDM system.

From February through March 2002, sixteen rockfishes representing three species were collected from Oregon Coast Aquarium and Newport fish market and examined far nematodes. During this study, a total of 157 Anisakis type larvae were recovered from Sebastes spp. and parasitized for an average infection prevalence of 50.0%. The yellowtail rockfish, S. flavidus, darkblotched rockfish, S. crameri, and canary rockfish, S. pinniger examined were infected with 110 Anisakis simplex larva, 30 Contracaecum spp. larva and 17 Pseudoterranova decipiens larva. Of the rockfishes examined, 75.0% carried Sebastes crameri, and 12.5% S. flavidus and S. crameri, respectively. The sites of infection far Anisakis type larvae were the intestine, omentum, and stomach walls. A. simplex larvae infected 60.0% on S. crameri and 33.3% on S.flavidus and S. pinniger respectively. The prevalence of Contracaecum sp. larvae and Pseudoterranova decipiens larvae on S. pinniger was 33.3%. The intensities of A. simplex larvae ranged from 1 to 87 in S. flavidus, S. crameri, and S. pinniger. The intensity of Contracaecum spp. larvae and P. decipiens larvae ranged from 0 to 30 in S. pinniger.

The provision of spatial data is a key infrastructural requirement for the promotion of economic growth, environmental quality, social progress, etc. 4S technology integrates 4 kinds of systems that process spatial data: GIS (Geographic Information System), GNSS (Global Navigation Satellite System), ITS (Intelligent Transport System), and SIIS (Spatial Imagery Information System). Spatial data processing field is expected to get synergy effect and overcomes development limit of individual unit technology via 4S technology. This paper discusses both the development of 4S-kernel technology and the construction of 4S-based framework, In the development of 4S kernel technology, we will concentrate on the following issues: the development of 4S base components for reciprocity integration among GIS, SIIS, GNSS and ITS technologies, the development of 4S-Mobile S/W and H/W, 4S-Van components, and national LBS technologies. And in the construction of 4S-based framework, we will especially concentrate on the ISP for overall 4S technologies, the international cooperative research center, and the guide model deduction for supervision and certification of 4S projects. Finally, we examine about how the construction of 4S-baed framework affects 4S industry.
