  • This study is for the size calculation of classroom based on the size of human body and teaching tools. The curriculum of Elementary school has been changed since 1960. It has been reflected on the size of classroom of elementary school. The new education curriculum-the 7th curriculum- demands various activities in classroom. And the Ministry of Education repealed the statute about the facilities of the schools on September in 1997. So we need to different size of unit space of the classroom in elementary school because the size of classroom will affect the quality of education. It is generally known that a part of human body-size has an invariable proportion with human's status, age and weight. In this study, regression analysis is used to find out a part of human body-size of Korean. Then the size of classroom is calculated by the part of human body-size, teaching tools and the type of desk arrangement.

  • Recently, Fishermen have required to expand the circumference of trap entrance for conger eel because it was difficult to take the catch out as well as to put the baits into. A series of fishing experiments was carried out in coastal areas of Tongyoung, Korea in 2008 and 2009 using the traps to describe the effect of the entrance size on the catch. The experimental traps (five types) were used in filed experiments with four types circumference size traps (140, 180, 220 and 260mm) with mesh size 22mm and another type was used the same one usually using in filed with mesh size 35mm (750mm circumference). The experiment results were, the conger eels of total length 35mm more or so were caught 85, 93, 142 and 176 individual by the experiment traps with mesh size 22mm as increase circumference size from 140mm to 260mm, respectively. And the small conger eels of the total length below 35mm to be prohibited to catch by law were caught 145, 160, 288 and 304 individual according to increase the circumference size of trap, respectively. In addition, in case of the trap with mesh size 22mm, bycatches were 230 - 260 individuals and much more than bycatches of the trap with mesh size 35mm. In conclusion, when we expand the circumference size of trap according to fishermen's requirement, we should review not only economic of fishery but also increasement the bycatch of non-target fishes and small size fishes.

  • Texts and icons are used to deliver the safety and health information on pesticide labels. This study surveyed the standards or guidelines regarding the presentation formats of texts and icons used in pesticides. Also, the text and icon formats being used in the 50 pesticide products in Korea were investigated in the aspects of size, font (texts only), color. From the guideline survey, it was found that while the guidelines for the text fonts and colors in pesticides were suggested, there was no detailed guidelines about the text size. For the icon presentation, it was regulated that the icon size for the pesticides should be larger than $7mm{\times}7mm$, and this size was equivalent to the size when the reading distance of 28 ㎝ was applied to other two guidelines. From the sample survey of the 50 pesticides, it was found that the small text size being used in the 50 pesticides was 1mm (3pt), and this size was considered to be very difficult to be read, particularly by old people. The minimum size of the texts for the toxicity of the pesticide, the very important safety information, was found to be 1.5 mm, which is considered to be very uncomfortable to be read. The size of icons were varied from 2 to 12 mm, and the total average size was 4.6 mm. The 149 icons from a total 187 icons (80%) were smaller than the icon presentation guideline ($7mm{\times}7mm$), and the reason for the small icon size might be the small area of the label of the pesticides. Thus, more detailed guidelines for the text size and more practical guidelines for the size of icons are required.

  • The purpose of this study is to investigate various information relating to research on the dimensions of clothing used in the sale of products via the internet that used to target global SPA((Specialty Store Retailer of Private Label Apparel) brands sold in Korea. A total of 12 SPA brands including seven global SPA brands and five national. SPA brands were surveyed in this study. Brands were chosen net sales and consumer preferences the last three years. In all SPA brands, literal size designation such as S, M, L and numeric size designation such as 0, 2, 4 or 32, 34, 36 etc. were mixed, but in case of Jean, the size codes mark waist circumference were dominant. European size codes were more common in case of European brands while literal codes were more dominantly used for American size codes with in the US brands. By reviewing the measurement information of the body and product size, the product measurement methods of UNIQLO, FOREVER 21 and TOPTEN were much more accountable and excellent than other brands. However, most of the others didn't offer proper information such as pictograms or figures about measurement methods relating body sizes and product sizes. In addition, most of global SPA brands offered size conversion chart which consumers could reference, however of none of the national SPA brands offered a conversion size chart on their website. Regardless of the type of clothing, the coverage of clothing size was higher than in global SPA brands such as H&M GAP compared to national SPA brands. In particular, 8seconds did not present apparel size ranges that fit consumers' individual clothes sizes.

  • The effect of structure size on the nominal strength of unidirectional fiber-polymer composites, failing by propagation of a kink band with fiber microbuckling, is analyzed experimentally and theoretically. Tests of novel geometrically similar carbon-PEEK specimens, with notches slanted so as to lead to a pure kink band (without shear or splitting cracks), are conducted. The specimens are rectangular strips of widths 15.875, 31.75. and 63.5 mm (0.625, 1.25 and 2.5 in and gage lengths 39.7, 79.375 and 158.75 mm (1.563, 3.125 and 6.25 in.). They reveal the existence of a strong (deterministic. non-statistical) size effect. The doubly logarithmic plot of the nominal strength (load divided by size and thickness) versus the characteristic size agrees with the approximate size effect law proposed for quasibrittle failures in 1983 by Bazant This law represents a gradual transition from a horizontal asymptote, representing the case of no size effect (characteristic of plasticity or strength criteria), to an asymptote of slope -1/2 (characteristic of linear elastic fracture mechanics. LEFM) . The size effect law for notched specimens permits easy identification of the fracture energy of the kink bandand the length of the fracture process zone at the front of the band solely from the measurements of maximum loads. Optimum fits of the test results by the size effect law are obtained, and the size effect law parameters are then used to identify the material fracture characteristics, Particularly the fracture energy and the effective length of the fracture process zone. The results suggest that composite size effect must be considered in strengthening existing concrete structural members such as bridge columns and beams using a composite retrofitting technique.

  • Purpose: Adequate nutrition is to be provided for normal growth and development during early childhood. Currently, childcare teachers provide lunch to most children in Korea. The purpose of this study was to investigate the portion size provided by teachers and examine the effect of education on food serving size. Methods: The subjects were childcare teachers (n = 120) in charge of children aged 3-5 years at a daycare center in Hanam-si. The survey was conducted through questionnaires which included questions on the general characteristics of the teachers, their nutritional education status, and the source of nutrition information. In addition, the portion sizes of items on the menu currently provided to children were measured and the data were analyzed. To assess the effectiveness of education in determining serving size, the subjects were randomly equally divided into two groups. In the first group (n = 60) theoretical education on nutrition and serving sizes was given, whereas in the second (n = 60), practical education on these topics was provided. Results: The difference between the actual portion size of rice and the serving size announced on the menu was observed to decrease along with the increase in the experience of the teacher, although the differences in the main dish and kimchi were higher. The gap between the serving size mentioned in the menu and the portion size distributed widened as the age of the teachers increased. Notably, the difference between the portion size and the serving size of food decreased after both practical and theoretical education. Furthermore, the effect of education on the serving size of the main dishes (p < 0.001), side dishes (p < 0.01), and kimchi (p < 0.01) was observed to be greater in the practical education group than in the theoretical education group. Conclusion: Regular education should be provided to teachers on the serving sizes mentioned in the menu, as the quantity of food served depends on the experience and age of teachers. In the case of rice, theoretical education alone sufficed to ensure a proper serving size. However, hands-on training on the main and side dishes, and kimchi would be much more helpful.

  • This study suggest the size designation and standard nude size in relation to upper and lower garments for casual clothing brands targeting men aged 25 to 34. The nude size designation of upper garments was set at intervals of 5cm based on the bust (97cm). The clothing industry has used different nude size and designations; therefore, the following measurements were established to correspond to each other: bust 87cm- designation 90, bust 92cm- designation 95, bust 97 cm-designation 100, bust 102cm- designation 105, and bust 107cm- designation 110. The nude size designation of lower garments was set at intervals of 2cm based on the waist circumference (omphalion) and the nude size; the clothing designations were used equally. In addition, the standard nude size for upper and lower garments was set at intervals of bust (97cm) and of waist circumference (82cm), respectively, in order to suggest a detailed size.

  • The life cycle of butterflies is closely related to the growth of food plants and, through a prolonged coevolutionary process, has undergone an ecological adaptation. So, it is important that control the egg-laying number and place to secure enough food plant by female adult to guarantee the survival of the larvae. To study whether oviposition control of the Luehdorfia puziloi takes into greater consideration food plant leaf biomass or leaf abundance, correlation among the egg cluster size, the leaf size, and the number of leaves around egg clusters was investigated. According to the results, the egg clusters size exhibited positive correlation with the leaf size of food plants on which eggs had been laid but did not do so with the number of surrounding leaves. In addition, the number of egg clusters laid exhibited positive correlation with the number of surrounding food plant leaves but not with the leaf size on which eggs had been laid. Consequently, for the Luehdorfia puziloi, the females' recognition of the leaf size seems to be the most important factor in the egg cluster size, and the number of egg clusters had positive correlation with food plant density per unit area.

  • The problem of fitting of children's clothing was researched through survey papers. The survey subjects were the mothers of elementary school students (grade 1 6) and the appropriateness of size, satisfaction with size, and fittings were asked. The survey area was divided into urban and rural areas. The following is the result: The children's clothing was mostly purchased in stores that carry lower-middle price range. The elements considered upon purchase were in the order of price, size, color and patterns. The frequency of purchase is 2 outfits a year, and the highest rate purchase was shown during the change of seasons. The size was picked through trying on the garment. The preferred indication of size was the one marked according to body size. The most popular size upon purchase was one size bigger than the proper fitting size. Mothers want their children to be able to wear one outfit for two years and actually children were able to wear them for two years. The highest degree of satisfaction upon proper fitting was bust girth and shoulder breath. The most frequent reason for a new purchase is the length. The most frequent dissatisfaction is the way buttons are sowed on.
