The measuring rule Is to extimate a size of a physical solid and its standard was each part of body since the beginning of the world. Korean traditional measuring rule was "Kyul Boo Sok Pa Bob". It bases on wreth of farm land and means a handful and a bundle. It was the real Korean traditional measuring rule though it was a influence on Chinese rule. And in Koguryo it had an effect on Japanese′s. In Chosun dynasty the King Sejong imprived the measuring rule and regylations in such a way to meet the realistic needs of civil lives. He put in good order by a proportions of the musical scale. It was one of fille correct ways to preserve the measuring rule and based on "Kyul Beo Sok Pa Bob"too. So ill that time the measuring rule for Korean traditional costume′s length was 46.703cm. In king Soonjo it′s length was 49.254cm and in 1926 it changed 50cm by the metric system. In 1990s the standard length has a difference in regions, 30cm, 45cm, 50cm, 54.5cm, 55cm and 60cm. As a result of the actual object investigation by regional measuring rule for Korean traditional costume it can reduce an accidental error when use the standard measuring rule, 50cm.

This study was conducted to analyze the difference in mechanically improved properties by distinguishing α-chitin and β-chitin for Poly(L-lactic acid)(PLLA). First, dissolution of chitins was established by mixing polar solvents hexafluoroisopropanol (HFIP) and trifluoroacetic acid (TFA) in appropriate proportions. Under these conditions, the dissolved chitin was used for electrospinning with other polymers. The electrospun nanofibers of the PLLA and chitins were successfully produced. Compared to the pristine state, when chitin was added to PLLA, the tensile strength increased 1.41 times (α-chitin), by 1.61 times (β- chitin), respectively. Based on this, it was confirmed that α- and β- chitin could be strategically used for different polymers. The results also suggest that chitin can be applied to various fields as good reinforcing material as well as electrospinning.

To evaluate the influence of burrowing substrate on the rearing performance and ambicoloration of cultured flounder, Paralichthys olivaceus, we compared the daily food intake (DFI), feed efficiency (FE), survival, growth, proportion of pigmented skin on the blind side, and proportion of ambicolored fish. We reared juvenile flounders [total length (TL) $4.46{\pm}0.06cm$, body weight (BW) $0.77{\pm}0.03g$] in dark-green fiberglass-reinforced plastic (FRP) aquariums without (control) or with gravel substrate at a density of 200 fishes/ton for 120 days. While there was no difference in survival rate or growth, the DFI was lower and FE higher in the group raised with substrate than in the control. The proportions of pigmented area on the blind side and ambicolored fish were significantly higher in the control tank. Therefore, the supplement of substrate on the aquarium bottom positively affects the feeding efficiency, and inhibits abnormal pigmentation on the blind side in flounder farming at high density.

The purpose of this study was to investigate the range of variation for commonly accepted ease in a business jacket and thus to find solutions to the problem of fit and ease in ready-to-wear jackets. This study was based on anthropometric measurements, pattern measurements, which were used to calculate ease amount according to each jacket part. The survey subjects were 493 males, between 25 to 59 years old, buying a jacket at stores in Seoul. In the results, the aesthetic purpose of a business jacket(custom-fit jacket) was clearly observed by the means of controlling the ease amount at chest, waist and hip. The ease at chest and waist(ready-to-wear) clearly revealed a difference among prototypes. This result can be explaned by the regular drops and the similar length-width proportions between sizes in ready-to-wear Jackets. Therefore, customers with varying body drop differences, who had to choose a homogeneous jacket drop, experienced too much ease at the Waist and Hip compared with custom-fit customers. In addition, the height could be an integral factor to affect the ease of jacket length and sleeve length. The ease at these parts was significantly different among height groups and showed negative relationships.

Purpose: This study was conducted to identify activities of daily living, depression and self-rated health and related factors for Korean Elderly. Methods: Data from the survey for the Korean Longitudinal Study of Aging in 2010 were used. The data were analyzed using frequencies, weighted proportions, and hierarchical multiple logistic regression. Results: Significant difference was observed in health status induced by socioeconomic status between men and women, but not among age groups. Socioeconomic status was strongly associated with self-rated health among male and female elders. Being unschooled and low net family asset were significantly related with dependency in activities of daily living and depressive symptoms among men. Only low net family asset was significantly related with depressive symptoms among women. Family support provides a slight decrease to the negative relationship between socioeconomic status and health status, especially depressive symptoms. Conclusion: This study suggests that interventions to reduce health inequalities should target elderly with lower socioeconomic status and with poor family support, using a gender-specific approach.

The author made a periodontal survey on 2,000 Korean adolescents in Seoul special city and Kyoungki-Do, to detect periodontal conditions and treatment needs. The obtained results were as follows: 1. 1.20% of adolescents had healthy periodontal tissues. 2. 11.95% showed only the gingival bleeding on probing, 66.55% had the calculus. 3. The proportions of adolescents with pocket depths about 4 to 5mm and over 6mm were 19.95% and 0.35% respectively. 4. Periodontal treatment need proportion showed 98.80% in oral hygiene instruction and 86.65% in oral prophylaxis; mean number of sextants affected was 2.96. 5. 0.35% was needed complex periodontal treatment. 6. In the sex and regional distribution, girls were slightly higher than boys in periodontal treatment needs and seoul than Kyoungki-Do; but the difference was not significant statistically.(p<0.05) 7. In the age distribution, periodontal treatment needs did not increase evidently with age; but comparing those for 15 years old with 19, the latter was slightly higher than the former.(p<0.05)

This study was conducted to develop an improved method for oocyte pick-up(OPU) with finger-sensibility using ultrasound-guidance from ovarian follicles in Holstein heifers. Oocytes were aspirated from ovarian follicles of clear-outline (>2mm), obscure-outline and invisible($\leq$ 2mm) on ultrasound images with 3 different vacuum pressure(40, 80, 120mmHg). Total number of oocytes recovered/follicles were 309/237(130.4%). 113/80(141.3%) and 107/74(144.6%) with 40, 80 and 120 mmHg of vacuum pressure, respectively. Mean number of oocytes recovered was higher in 2 OPU/week (18.3$\pm$5.3) than 1 OPU/week(14.5$\pm$4.1), but this difference was not statistical1y significant. The recovery rates were not affected by the number of OPU as 135.6%(282 oocytes/208 follicles) in 1~20 OPU, 137.7% (168/122) in 21~40 OPU and 148.4%(92/62) in 41~60 OPU, respectively. The proportions of good oocytes (Grades I) recovered were not significantly different by the number of OPU until 40 OPU(12.4% in 1~20 OPU vs 16.7% in 21~40 OPU). However, a significantly(P<0.05) lower recovery rate resulted from more than 40 OPU compared to less than 40 OPU(7.6%). These results imply that more fertilizable oocytes can be produced from invisible-immature follicles by transvaginal aspiration with finger-sensibility from Holstein heifers.

Purpose: This study was conducted to compare the degree of depression between men and women and to identify factors influencing their depression. Methods: Participants in this cross-sectional descriptive study were 263 persons over 65 years old (men: 103, women: 160). Data were collected through face to face interviews using questionnaires and were done in two urban areas in 2010. Research instruments utilized in this study were SGDS, MMSE-K, SRH, FILE, sleep pattern scale, family and friend support scale, and social support scale. Multivariate regression analysis was performed to identify factors influencing depression in elders. Results: The proportions of participants with depression were significantly different between men and women (52.4% vs. 67.5%). Regression model for depression in elderly men significantly accounted for 54%; disease stress (32%), economic stress (10%), perceived health status (4%), and family support, educational level, age, and hypertension. Regression model for depression in elderly women significantly accounted for 47%; disease stress (25%), perceived social loneliness (8%), friend support (5%), family stress (4%), and sleep satisfaction, and family support. Conclusion: Results demonstrate that depression is an important health problem for elders, and show gender differences for factors influencing depression. These results could be used in the developing depression prevention programs.
