This study aims to categorize age groups for shoes manufacturing including shoes size and boot tree development for Koreans. In order to carry out the research, the characteristics of different parts of foot in relation to size are analyzed according to age and sex, making use of human body measurement database. As a result of statistical analysis, it was found that the measurement items such as foot length, metatarsal tibiale, foot breadth and instep circumference of a person reached the range of standard deviation and average numerical figures of an adult group (18-24) from the age of 14 in men's case, and from 12 for women's case, which indicates the time of completion of their foot growth. Based on these findings where males of 14 years old and females of 12 are within similar measurement range to adults, it is necessary to categorize the age groups for shoe sizing system into the following four groups: males 13 years old or under, males 14 years old or over, females 11 years or under, and females 12 years or over. The proportional measurement produced by dividing each measurement item of foot parts by foot length was compared in an independent samples t-test, and there were meaningful differences according to different foot shapes of the two age groups of males 13 or under - males 14 or over, and females 11 or under - females 12 or over. Also, the independent samples t-test for the age groups of males 13 or under - females 11 or under, and males 14 or over - female 12 or over, showed similar meaningful differences, which indicates the differences in foot shapes of male and female during the period of growth.

Background: In breast cancer (BC), it has been suggested that nuclear overexpression of p53 protein might be an indicator of poor prognosis. The aim of the current study was to evaluate the expression of p53 BC in Kurdish women from the West of Iran and its correlation with other clinicopathology figures. Materials and Methods: In the present retrospective study, 231 patients were investigated for estrogen receptor (ER) and progesterone receptor (PR) positivity, defined as ${\geq}10%$ positive tumor cells with nuclear staining. A binary logistic regression model was selected using Akaike Information Criteria (AIC) in stepwise selection for determination of important factors. Results: ER, PR, the human epidermal growth factor receptor 2 (HER2) and p53 were positive in 58.4%, 55.4%, 59.7% and 45% of cases, respectively. Ki67 index was divided into two groups: 54.5% had Ki67<20% and 45.5% had Ki67 ${\geq}20%$. Of 214 patients, 137(64%) had lymph node metastasis and of 186 patients, 122(65.6%) had vascular invasion. Binary logistic regression analysis showed that there was inverse significant correlation between lymph node metastasis (P=0.008, OR 0.120 and 95%CI 0.025-0.574), ER status (P=0.006, OR 0.080, 95%CI 0.014-0.477) and a direct correlation between HER2 (P=005, OR 3.047, 95%CI 1.407-6.599) with the expression of p53. Conclusions: As in a number of studies, expression of p53 had a inverse correlation with lymph node metastasis and ER status and also a direct correlation with HER2 status. Also, p53-positivity is more likely in triple negative BC compared to other subtypes.

To focus attention on milk and dairy products, we celebrate World Milk Day on the first day of June. Milk is a primary source of essential nutrients for newborn mammals, including humans. Milk and its by-products have been integral to human life since domestication of the dairy cow. Even though a large portion of the population is lactase impersistent, consumption of dairy products, including liquid milk, has been increasing over the last decade in Korea. Per capita annual consumption of dairy products in Korea increased to 61.3 kg in 2008, up from 49.4 kg in 1998. However, consumption of liquid milk has only increased marginally from 30.3 kg in 1998 to 35 kg in 2008. In 2007, the price of farm milk in Korea was the highest in the world. High dairy prices are forcing major manufacturers to find alternative, less expensive sources of milk, which has led to an increase in imported dairy products. Recently, the International Dairy Federation (IDF) published a special report containing the figures for world milk production, milk processing, and consumption. Understanding the current situation with regard to world diary production and the outlook for the industry could be useful during the present world economic crisis. The authors of this brief review summarize the status of dairy production in countries throughout the world, including Korea, along with some of the data published in the IDF annual report. The authors greatly appreciate the support of IDF Korea and the IDF for generously providing the data used in this paper.

The goal of this study is to support the children's pants construction methods that secure clothing size and fit appropriateness through proposed improvements of denim pants construction method focusing on 4-year-old boys. Depths interview on the actual condition, measurements and calculations for positions and ease of the clothing points corresponding to the body points actually worn were conducted for 47 denim pants of nine boys. "Characteristics of the areas worn" and "physical characteristics of lower body" were analyzed, and improvements of 4-year-old children's denim pants construction method were proposed. As the results, the different figures in "characteristics of the areas worn" between the existing children's pants construction methods and children's actual wearing habits were found, and identification of distinct children's lower body from adults' supports that we should avoid tracing adults' methods without reasons. Children's pants construction method on basis of actual wearing should be devised to solve fit problems. Improvements of children's method were proposed such as ease of girth by different area worn, ease of "elastic waist girth", the difference between "elastic waist girth" and "pattern waist girth", and the difference between "pattern waist girth" and "pattern hip girth" as considerations of pants girth items, and appropriate position "clothing waist girth" "pants hip length" level, "pants crotch length" level, "clothing knee length" level, and "pants outside length" level for pattern making as considerations of clothing length items.

There have been reported numberous cases of liver scanning in use of $^{198}Au$ colloid by many investigators, however, one in use of $^{113m}In$ colloid has not been reported as yet in this country. The dose of $^{113m}In$ for high diagnostic value in examination of each organ was determined and the dignostic interpretability of liver scanning with the use of $^{113m}In$ was carefully evaluated in comparison with the results of the liver scanning by the conventionally applied radioisotopes. The comparative study of both figures of liver scannings with the use of $^{113m}In$ colloid and $^{198}Au$ colloid delivered following results: 1. The liver uptake rate and clearance into peripheral blood were accentuated more in case of $^{113m}In$ colloid than in case of $^{198}Au$ colloid. 2. The interpretability of space occupying lesion in liver scanning with $^{113m}In$ was also superior to one with $^{198}Au$. 3. The figure of liver scanning with $^{113m}In$ colloid corresponds not always to the figure with $^{198}Au$. This difference can be explained by differences of phagocytic ability of reticuloendotherial system within liver. 4. In the liver scanning with $^{113m}In$ colloid, the spleen is also visualized even in normal examinee. 5. In the cases of disturbed liver function, uptake is more decreased in use of $^{113m}In$ colloid than in $^{198}Au$, in the spleen, however, the way is contrary. 6. With use of $^{113m}In$ colloid, the time required for scanning could be shortened in comparison with $^{198}Au$. 7. The filtration of $^{113m}In$ colloid for scanning prior to human administration gives an expectation for better scanning figure.

This research verified the usefulness and practicality of citrus peel extract as a natural dye. This study dyed cotton, silk, and cotton/mulberry fiber blended fabrics using citrus peel extract, and measured the dyeability and functional property to verify their usefulness and practicality. The dyeing affinity of the citrus peel extract was measured by dyeing under alkaline conditions to determine the temperature and time for optimal dyeing conditions of the solution. The results show that a temperature and time of $60^{\circ}C$ and 30 minutes were optimal for dyeing cotton fabrics with citrus peel extract, $50^{\circ}C$ and 60 minutes for silk fabrics, and $60^{\circ}C$ and 60 minutes for cotton/mulberry fiber blended fabrics, respectively. In addition the results of measuring the color fastness of the cotton, silk, and cotton/mulberry fiber blended fabrics dyed with the citrus peel extract show that the color fastness was superior for washing, friction, sweat, and water. However, the color fastness for sunlight appeared to be slightly weak. In addition, it was found that fabric dyed with the citrus peel extract showed partial antimicrobial properties. The antimicrobial property appeared the greatest in the silk fabric. The cotton/mulberry fiber blended fabrics had 90% or more Staphylococcus aureus present, but the antimicrobial properties were not high in the cotton fabric. Additionally, the heavy metal content, which is harmful to the human body, appeared to be lower than standard figures, so the dye was found to be innocuous to humans. Therefore, when the results of this study are put together, citrus peel extract is sufficiently useful and practical as an ingredient for a natural dye. Moreover, there is ample possibility to develop citrus peel dyed fabrics as environmentally friendly fashion materials.

Somatotype is human body shape and physique type which can be classified not only by the size, but also by the shape or posture of the body. Postural variations in the alignment of the back, shoulder, and neck can have an adverse effect on the fit of garments designed to hang from the shoulders. There have been some previous studies about the lateral upper torso by analyzing photographic measurements. In this study, 3D body scan images were used to classify the side somatotype of upper lateral method even though they are major data in the classification of upper torso. This study focused on following objective.; 1) To apply new and developing technology into the apparel industry analyzing 3D body scan images. 2) To classify upper laterla torso using the data through the new improver technology, 3D body scanner. 3) To propose basic materials for well fitted garments for each type of figure. The test subjects for this study were two hundreds nine female aged 19 years and up who were recruited in Cornell university body scan research team. Seventeen Variables(12 angles, 5 lengths) out of 3D body scan data were measured based on these landmarks and applied to analyze. The result of factor analysis indicated that 6 factors were extracted through factor analysis and orthogonal rotation by the method of Varimax and those factors comprise 62.5% of total variance. And the somatotype of upper body is classified into 3 types of figures according to cluster analysis; Bent forward posture, Straight posture, Swayback posture. Future study could be addressed about the somatotype of body by the age group based on the large database with wide variety of age.

A 7-year-old Jeju native boar was requested to the Veterinary Pathology Laboratory of Cheju National University with a clinical signs of anorexia, melena, lethargy and sudden death. At necropsy, four coalescing firm masses were occupied in the abdominal cavity between ventral surface of stomach and pancreas. Individual mass was a yellowish white in color and up to 6 cm in diameter. These masses were not encapsulated and bulged from the cut surface. Liver and spleen were enlarged and pale nodules were presented in these tissues. Some yellowish white nodules up to 5 mm in diameter were scattered in kidneys. Histopathologically, lymphoblastic tumor cells were occupied in the abdominal masses, multifocal areas of liver, kidneys, and spleen. Morphologically lymphoblastic tumor cells were round to oval in shape, and medium to large in size. They had round to oval nuclei, moderate amount of eosinophilic cytoplasm, and many mitotic figures. Immunohistochemistry revealed that tumor cells were CD3-positive and $CD79{\alpha}$-negative, consistent with T-cell lineage. Based on gross, microscopic findings and immunohistochemistry, this case was diagnosed as porcine multi-centric T cell lymphosarcoma. In animals, as in human, the T-cell lymphomas are generally more aggressive than B cell types and respond less well to therapy. In our best knowledge, this is the first report for porcine T cell lymphosarcoma in Korea.

Purpose: The evaluation of SUV (Standardized Uptake Values) for quantitative analysis in PET exam is the most significant. In PET exam, we make attenuation correction images by using $^{68}Ge$, $^{137}Cs$ or CT data. At this time, a distorted attenuation map affects quantitative analysis. After the exam using barium-sulfate and high density of barium contrast make attenuation map distorted. And then it brings bed influences on SUV. The aim of this study is to verify the relationship between high density barium-sulfate and SUV in PET exam. Materials and Methods By using $^{18}F$-FDG, we made barium-sulfate powder, density of 0, 1.5, 3, 5, 10 and 15% respectively and acquired PET and PET/CT images per each density. And we examined SUV variations from PET and PET/CT images according to differences of barium's density. Moreover, we finally calculated SUV causing variations in HU (Hounsfield Units) values to justify whether the differences of barium density bring any changes in PET/CT exam. Results: From PET images acquired from transmission scan with $^{68}Ge$, we got SUV figures from 6.46 to 6.8 in barium density between 0 to 15 percent. On the other hand, In PET images acquired from Tx scan that using CT, SUV was 6.77 to 23.73, derived from the same barium density. And CT HU values range from 29 to 2004. Conclusion: PET images from Tx data using $^{68}Ge$ weren't affected by barium density and had no differences in SUV. But in the PET/CT images using CT Tx data, there's considerable variations in HU and SUV values according to a difference of barium density in HU values. To perform a precise examination, barium sulfate should be removed from a human body before performing a PET exam.

This study looked at how to establish effluent limitation standards for formaldehyde, a toxic chemical widely used in industries. To this end, we reviewed Water Quality Based Effluent Limitation (WQBEL), Technology Based Effluent Limitation (TBEL), and water quality criteria for protection of human health and aquatic organism. Based on the results, we estimated formaldehyde effluent limitation standards appropriate to control water quality of industrial wastewater in Korea. However, this study has limits due to the lack of some data necessary in estimating formaldehyde effluent limitation. For example, although water quality criteria based on non-carcinogenic properties of formaldehyde were calculated, those based on carcinogenic properties were not be able to estimate because of the absence of applicable cancer potency factor q1. Without applicable factor, we calculated water quality standards for formaldehyde based on water quality criteria of advanced countries including the United States, while with no water quality standard we referred to applicable drinking water quality standards of other countries. For eco-toxicity based on water quality criteria, proper figures could not be calculated since there have been few reliable data.
