This study investigates the progress of obesity in men from childhood to adulthood, by analyzing the measurement references from the 5th Size Korea. It also seeks to analyze the characteristics of obese figures through the comparison of body proportions to normal-weight people, to provide a basic reference for the development of new size categories and improved pattern grading. The age range is divided into three groups: children (2-7), teenagers (13-18), and adults (19-39). The results of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows. The ratio between width and circumference for each part of the body was investigated according to body weight that was grouped into three different categories of low, normal, and obese body weights. The result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference in having a thick body shape. According to the results that compared the ratio of the circumference of each body part divided by the waist circumference, the obese group showed a low ratio that indicates that they have a bigger waist circumference than other parts of the body. Two factors are identified as contributing to obesity in analyzing the ratio of the circumference of body parts divided by waist circumference. Using the factor loadings of the upper and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; lower body obesity, abdominal obesity, and upper body obesity. The obese groups of children and teenagers were mostly in body shape with lower obesity and abdominal obesity, whereas the adults group showed the obesity present in the upper body obesity that have fewer cases in lower body obesity.

Fine needle aspiration cytology is considered as a useful diagnostic procedure in management of patients with breast lesions. This study was undertaken to evaluate the scoring system of Masood in the interpretation of breast aspirates, to establish the most useful cytologic criteria for the diagnosis of breast lesions, and to subclassify the benign breast diseases. To assess the feasibility of a cytologic grading system, 57 cases of benign breast disease, 61 cases of malignant breast disease were studied, respectively. The aspirates were evaluated for the cellular arrangement, the degree of cellular pleomorphism and anisonucleosis, and the presence of myoepithelial cells and nuceoli. Values ranging from 1 to 4 were assigned to each criterion and the sum of the individual values was made for each case. The presence of stroma, apocrine metaplasia, foamy histiocytes and inflammatory cells, background of the smear, and cellularity were also evaluated. Cut-off value of the scoring system of Masood between benign and malignant lesion was 15. Among the cytologic criteria, cellular arrangement, presence of myoepithelial cells, nucleoli, and stroma, status of chromatin pattern, and background of smear were useful criteria in the differentiation between benign and malignant lesions. Application of the scoring system of Masood does not always make the accurate diagnosis and the subclassification of benign breast disease.

This study was carried out to investigate the effects of housing system on the carcass and meat qualities of Hanwoo (Korean cattle) bulls. Fourteen 6 months-old male calves were randomly divided into two groups. The first group was individually tethered using double neck-bar tethers. The second group was collectively loose-housed in the pen. They were raised for 15 months prior to slaughter. At 24 h post-slaughter chilling, the carcasses were weighed and evaluated by official grader for carcass traits. At 48 h post-slaughter chilling, the M. longissimus at the $12-13^{th}$ thoracic vertebra from each carcass was collected and stored at $4{\pm}0.2^{\circ}C$ for 7 days for meat quality analysis. There were no significant differences in dressing percentage and carcass yield index between groups. Meat from loose bulls had lower marbling score (p<0.05) and fat content (p<0.01) but higher PUFA concentration (p<0.001) than that from tethered bulls. There were no significant differences physical and sensory properties, aroma pattern, TBARS value, metmyoglobin concentration and CIE color values during refrigerated storage between groups. Compared to tethering, loose-housing bulls produced lower fat content and healthier meat without different physical properties, acceptability, and lipid and color stabilities.

Oral tongue squamous cell carcinoma (OTSCC) is the most common oral cancer subtype with a maximum propensity for regional spread. Our objective was to study if p53 expression might have any correlation with aggressive patterns of invasion within oral tongue cancers as well as with the histologically identified degree of oral tongue dysplasia. p53 immunoexpression was studied using immunohistochemistry in early staged OTSCCs (n=155), oral tongue dysplasias, (n=29) and oral tongue normal specimens (n=10) and evaluated for correlations with histological and clinicopathological parameters. Our study (n=194) showed a pattern of p53 expression increasing with different grades of tongue dysplasia to different grades of invasive OTSCC (p=0.000). Among the OTSCC tumours, positive p53 expression was seen in 43.2% (67/155) and a higher p53 labelling index was significantly associated with increased Bryne's grade of the tumour invasive front (p=0.039) and increased tumour depth (p=0.018). Among the OTSCC patients with tobacco habits, (n=91), a higher p53 labelling index was significantly associated with increased risk of local recurrence (p=0.025) and with lymphovascular space involvement (p=0.014). Evaluation of p53 through varying degrees of dysplasia to oral tongue cancer indicates that p53 expression is linked to aggressive features of oral tongue cancers and tongue precancers entailing a closer monitoring in positive cases. Among the OTSCCs, p53 expression is associated with tumour aggressiveness correlating with increased grading of invasive tumour front and tumour depth.

Background: Esophageal squamous cell carcinoma (ESCC) is a common cancer with poor prognosis. It has been hypothesized that Oct4 positive radioresistant stem cells may be responsible for tumor recurrence. Hence, we evaluated Oct4 expression in ESCC in pre-treatment, post neo-adjuvant residual and post-surgical recurrent tumours. Materials and Methods: Endoscopic mucosal biopsies were used to study Oct4 expression and the observations were correlated with histological tumor grades, patient data and clinical background. Results: All patients presented with dysphagia with male predominance and a wide age range. Majority of the patients had intake of mixed diet, history of alcohol and tobacco intake was documented in less than half of the patients. Oct 4 expression was significantly higher in poorly differentiated (PDSCC) and basaloid (BSCC) subtypes than the other better differentiated tumor morphology. Oct4 was also expressed by adjoining esophageal mucosa showing low grade dysplasia and basal cell hyperplasia (BCH). Biopsies in PDSCC and BSCC groups were more likely to show a positive band for Oct4 by polymerase chain reaction (PCR). Dysplasia and BCH mucosa also showed Oct4 positivity by PCR. All mucosal biopsies with normal morphology were negative for Oct4. Number of tissue samples showing Oct4 positivity by PCR was higher than that by the conventional immunohistochemistry (p>0.05). Oct4 expression pattern correlated only with tumor grading, not with other parameters including the clinical background or patient data. Conclusions: Our observations highlighted a possible role of Oct4 in identifying putative cancer stem cells in ESCC pathobiology and response to treatment. The implications are either in vivo existence of Oct4 positive putative cancer stem cells in ESCC or acquisition of cancer stem cell properties by tumor cells as a response to treatment given, resulting ultimately an uncontrolled cell proliferation and treatment failure.

The objective of the study was to obtain standard sizes of body of the high school girls for designing clothes and developing pattern grading of clothes. In 1972, 342 students, selected by the stratified cluster random sampling method, at three high schools in Seoul were measured on forty-one items by the R. Martin method. Statistical techniques of mean, standard deviation, coefficient variable, maximum and minimum, range, t-test were utilized to analyze the data. The findings of the study were as follows ; 1. No differences were found among the age groups in the all measured variables. 2. Stature, bust girth, hip girth, acromion width, posterior waist girth/stature ratio of the high school girls were significantly smaller than those sizes of adult women. This result implies that those sizes will be increased as the students grow up. But upper arm girth, upper arm girth/bust girth ratio, and thigh girth/bust girth ratio were bigger than those sizes of adult women. Waist girth, thigh girth, total head height/stature ratio, acromion width/stature ratio, and foot length/stature ratio were nearly similiar to those of adult women. 3. According to the result of t-test, waist breadth, spinailiaca anterior height/stature ratio, thigh girth/bust girth ratio, and thigh/hip girth ratio of the 15 year old group were significantly different from those of the 16 year old group at the level of 0.05. Bust girth, weight, foot breadth, posterior croth length, and cervical height/stature ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.01. Hip girth, upper arm girth, waist breadth/stature ratio, and neck base girth/bust girth ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.05.

The objectives of this study were to investigate the progress of obesity in women from childhood to adulthood and to analyze the characteristics of obese figures through comparing their body proportions to normal-weight people, to provide a basic reference for development of new size categories and improved pattern grading. Body measurement was made on 6,704 women age between 7-39 in Sizekorea 2004 database. The age range was divided into three groups: children(7-12), teenagers(13-18) and adults(19-39). The result of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows: The ratio between width and circumference for each part of the body was investigated according to body weight which was grouped into three different weights of low, normal and obese body weights. And the result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference, having a thick body shape. And according to the result of comparing the ratio of the circumference of each body part divided by the waist circumference, the obese group also showed a low ratio, indicating that they have bigger waist circumference than any other body parts. By analyzing the ratio of circumference of body parts divided by waist circumference, three factors were identified as contributing to obesity. Using the factor loadings of the upper, distal and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; abdominal obesity, distal obesity and proximal obesity.

Automated visual grading system of lumber needs correct input image. In order to create a correct image of domestic red pine lumber 3.6 m long feeding on a conveyer, part images were captured using area sensor and template matching algorithm was applied to merge part images. Two kinds of template matching algorithms and six kinds of template sizes were adopted in this operation. Feature extracted method appeared to have more excellent image merging performance than fixed template method. Error length was attributed to a decline of similarity related by difference of partial brightness on a part image, specific pattern and template size. The mismatch part was repetitively generated at the long grain. The best size of template for image merging was $100{\times}100$ pixels. In a further study, assignment of exact template size, preprocessing of image merging for reduction of brightness difference will be needed to improve image merging.
