  • In our time the parent's role is changing from sexually differentiated to androgynous pattern. Mother's interction with infant includes caring and father's interaction especially have play. Father and mother share the caring and play because they have complementary nature. Infants have a tendency to show more positive responses to their fathers than mothers in play situations. For that reason we can help the promotion of father's interaction with his infant through ascertaining patterns of father-infant play interaction. This study was to find out patterns of father-infant play interaction in order to improve the Interaction between father and infant. Data was video-taped from 6 fathers and infants who were healthy and first-timed and 7-11 weeks old in their houses. I used Father-Infant Play Interaction Scale that was applied to father instead of mother as a care-giver. The scale was checked up by experts in this field for content validity and the reliability was 0.95 in this study. The results were as follows : 1. Father's play behaviors were the patterns of responses about infant's cue. The mean score was 33.16(SD, 9.11), This means they come up to the standard level of responses about infant's cue. 2. Infant's play behaviors were the patterns of responses about father's cue. The mean score was 7.00(SD,3.10). This means they get the higher level of responses about father's cue. 3. The patterns of simultaneous responses occured together between father and infant. The mean score was 9.58 (SD, 3.96). This means they reach the standard level of simultaneous responses between father and infant. 4. The patterns of interactional behaviors occured interpersonally between father and infant. The mean score was 49.75(SD, 15.80). This means they interact on the standard level of play interaction. In view of the results father's play interaction seems to reveal an average level and play patterns are similar to mother's. In order to ascertain definitely patterns of father-infant play interaction we need further research which has more subjects and variables to have important effects.

  • Fashion has been analyzed and explained in diverse ways. Fashion, like every phase of culture, is a reflection of the Zeitgeist. In order to understand the changing fashion we must understand the changing society. For fashion of a period are expressions of the interrelation of the various elements of the culture, including the social and political values, the economic and industrial progress, art, the development of technology, etc... Particularly fashion is closely connected with a style of art. In a style of art, futurism focused on the "dynamism" resulting from super-speed and high-technology. This study aimed to review literatures, fashion magazines, web-site in order to know how the dynamism of futurism is expressed in modern fashion. The results of this study were as follows; 1. Dynamism was expressed by means of lines, colors, patterns through the eyesights visually. Asymmetrical oblique lines, zig-zag lines or bold cutting expressed the mechanical and offensive dynamism. In contrast, such lines as curves and spirals expressed the soft and natural dynamism. Primary colors or complementary contrast expressed energetic and rhythmical dynamism. The geometrical patterns and automobile wheels patterns expressed dynamism resulting from mechanical aesthetics. 2. Dynamism was expressed through repeat of lines, colors, patterns, and textiles. Particularly Vinyl material, fluorescent material, metallic material, beads, and spangle expressed a strong dynamism. On the other hand, natural materials, paper and other similar ones are used to signify the orientation towards a futuristic high-technology society.y society.

  • Purpose: This ethnography was performed to explore patterns and meanings of healthy life among aged women using senior centers. Methods: The informants were 21 individuals aged 65 years and older at 2 community-based senior centers. Data were collected from iterative fieldwork through in-depth interviews and participant observations and analyzed using text analysis and taxonomic methods developed by Spradley. Field notes were used with follow-up interviews and dialogue between authors to enhance interpretation. Results: Patterns of healthy life among aged women using senior centers were categorized by age groups within the context of the four cultural elements of taking care of the body, relationality, temporality, and spatiality: active and passive control, maintenance of interdependence and individuality, expansion and maintenance of the daily routine, unity of peer relations and sustenance of family relations, spending time productively and tediously, and complementary and alternative space of the family relations. Conclusion: The informants in this study demonstrated healthy life by maintaining and strengthening continuous relationships developed in the senior centers without being isolated from the family and society. Patterns of their healthy life differed across age groups within the socio-cultural context. Therefore, interventions should be tailored to address age groups and community needs.

  • The purpose of this study is to identify trends in modern Korean clothing design through investigation and analysis of the types and respective characteristics of silhouettes, colors, materials, patterns, and decorations present. To this end, research methods such as literature research and content analysis through case study research were used. The results of the wedding magazine data analysis were largely classified by design element and based on such, the conclusions are as follows. First, in the analysis of silhouettes, the appearance rate of traditional items decreased over the selected period and that of modified items increased. Second, among the same colors, adjacent colors, proximity complementary colors, contrast, and other harmonies, adjacent color harmonies showed the highest rate of appearance. Third, the cases where the same materials were used for the top and bottom elements showed a similar appearance rate as those where different materials were used. It was also concluded that traditional materials are being replaced by modern materials. Fourth, regarding the arrangement of patterns, the appearance rate of the absence of patterns gradually increases. Fifth, there were more case of decorations than those of none. This study made it possible to grasp the changes in trends of modern Korean clothing from 2011 to 2020 and provide basic data for the development of the Korean clothing market industry.

  • Dietary pattern analysis is important complementary approach for identifying associations between diet and chronic disease. A case-control study was conducted in order to examine dietary patterns and the risk of colon cancer in Korea. Data were collected from both 137 cases with either colorectal cancer or large bowl adenomatous polyps and 134 controls regarding social-demographic characteristics and food intake using a semi-quantitative food frequency questionnaire. We conducted factor analysis and identified 6 major dietary patterns: 'Well-being diet' characterized by higher intakes of potatoes, yogurt, soybean paste and vegetables, 'Meat & fish', 'Milk & juice', 'Pork & alcohol', 'Rice & kimchi', and 'Coffee & cake'. We calculated factor scores for each participant and examined the associations between dietary patterns and colon cancer risk. After adjusting for potential confounders, there was a relative risk for colon cancer of 0.16 (95% confidence interval, 0.07 - 0.34) when comparing the highest with the lowest tertile of the 'Well-being' pattern. Significant trends of decreasing risk of colon cancer also emerged with the 'Milk & juice' (OR = 0.40, 95% CI = 0.20 - 0.79). In contrast, inverse associations of the risk were found for 'Pork & alcohol' (OR = 1.92, 95% CI = 0.93 - 3.97), 'Coffee & cake' (OR = 2.18, 95% CI = 1.07 - 4.46). For the 'Meat & fish' pattern, the decreased risk of colon cancer was observed in the second tertile, but not in the highest tertile when comparing to the lowest. The 'Rice & kimchi' pattern had a nonsignificant association with the risk. These data suggest that major dietary patterns derived from the FFQ associated with the risk of colon cancer in Korea. Since foods are not consumed in isolation, dietary pattern research in natural eating behavior may be useful for understanding dietary causes of colon cancer.

  • In order to reflect traditional elements in modern design, designers should be able to creatively apply elements of traditional Chinese clothing. To understand this, a deep understanding of and insights into the traditional clothing culture are required. In this study, the characteristics of traditional Chinese women's clothing from the Wei, Jin, and Northern and Southern Dynasties of China to the Qing Dynasty were analyzed by dividing them into silhouette, color, pattern, materials, and detail. The characteristics of the silhouette were classified into A, H, X, and O types, of which types A and H were the most common. As for the color characteristics, there are relatively many five cardinal colors, and for the contrast of colors complementary colors were mainly used. As the for pattern characteristics, real patterns, animal patterns, character patterns, geometric patterns, and mixed patterns were used. Four types of materials were mainly used: silk, hemp, cotton, and wool. The detail characteristics were also anlyzed by classifying them into collar, sleeve, neckband, and gusset. Based on the results of this analysis, a satisfaction survey was conducted on the design of modern Chinese women's clothing. The result of satisfaction with design elements showed that the images of vest and suit were most preferred, H and X silhouettes, and yellow and white were the most preferred. Geometric and plant patterns were preferred, as were silk and acetate materials. Based on the result of chi-square analysis of design element preferences according to the characteristics of the subject, there was no difference according to occupation, residential area, or income, and there were differences in silhouette, color, materials, and detail according to age.

  • Viral RNA was extracted from purified Chinese cabbage strain of turnip mosaic virus (TuMV-Ca) from infected leaves of turnip. Polyadenylated genomic viral RNA was recovered by oligo (dT) cellulose column chromatography and used as a template for the synthesis of complementary DNA (cDNA). Recombinant plasmids contained cDNA ranged from about 900 bp to 2, 450 bp were synthesized. Among the selected 41 transformants, pTUCA31 and pTUCA35 had over 2 Kbp cDNA insert. Restriction endonuclease patterns of the clones examined were very similar among them. Clones pTUCA23 and pTUCA31 were overlapped with pTUA35. The longest clone pTUCA35, encoding 3'-end, showed that it contained two sites for EcoRI, and one site for BamHI, ClaI, HincII, SacI and XbaI, respectively. The restriction mapping indicated that the clone pTUCA35 contained partial nuclear inclusion body gene, complete coding region of the coat protein and 3' untranslated region of TuMV-Ca genomic RNA.
