Online shoppers are not able to try clothing on. Therefore, the pictures of clothing on the website play a significant role when shoppers make decision on their purchase. There are generally three different ways to show clothing at online shops. The first one is showing only clothing images, and the second one is showing the pictures that have actual fitting models wearing clothing on (In this case, Model's face is mostly not shown in the picture.), and the third is showing the pictures of professional fitting models who wear goods. The shopping malls adopt each of the different ways but little is known about affect on purchasing from these three ways. The aim of this study is to figure out how the online shopper's emotional status is affected by these three ways of presenting pictures of clothing. At first, we developed a set of adjective words of human emotion to set up the evaluation criteria for user's emotional status. Those adjectives are originally from the precedent research on human emotion. To cut 99 adjectives down to a proper number for the criteria, we conducted a preliminary survey, and finally, 5 adjectives are selected as appropriate criteria for evaluating users' emotional status while they are shopping. Those five adjectives are 'possess','sensual', 'unique', 'tasteful', and 'stylish'. Then, we conducted the main survey showing 10 kinds of cloth (each cloth was consist of 3 ways). And in the page of model images, we measured the model's preference for understanding the relation with customer's emotion criteria of the product. As a result of the test there was statistically significant difference between product only images and anonymous images, but there was no significant difference between anonymous images and model images. And the preference of the model and value of the emotion criteria have large correlation except 'unique' criteria. It is expected that the result in this study will help to build new marketing strategy which satisfy customers' emotion.

The purpose of this study was to find out any difference and correlation between the cardiac structure and its function according to the level of obesity as evaluated by waist measurement and BMI (body mass index) in healthy adults. For research subjects, the study selected a final 519 subjects excluding 198 subjects aged 55 or over out of 717 subjects who received echocardiography through a medical checkup at J General Hospital. For the criteria for obesity, men were defined as being obese in case their waist measurement was over 90 cm, whereas women were defined as being obese in case their waist measurement was over 80 cm. Also, regarding the BMI criteria, in case a person's BMI was 30 kg/$m^2$, the subject was classified as belonging to an obese group, and in case a person's BMI was between 25 kg/$m^2$ and 30 kg/$m^2$, the subject was classified as belonging to an overweight group. Concerning the evaluation of cardiac structure and function, they were evaluated using two-dimensional, M-mode, doppler echocardiography. According to the stage of obesity in accordance with waist measurement and BMI, the cardiac structure showed both eccentric and centripetal changes, and the cardiac function was also discovered to show differences according to the stage of obesity. In addition, also in the overweight group, which is a prior stage to obesity, out of the criteria for obesity classification according to BMI, there were differences in the cardiac structure and function. Also, both the waist measurement and BMI were found to have a correlation with cardiac structure and diastolic function. Consequently, cardiac structure and function are correlated with BMI and waist measurement, which are anthropometrical variables, and obesity is assumed to induce not only structural change but also functional change of the heart.

This study was performed to investigate the physical, chemical and microbial characteristics of Gwamegi to provide basic data for the standardization of marine processed foods and for the improvement of the quality of commercial Gwamegi. The acid values of commercial Gwamegi were 5.8, 5.3 and 5.2 mg KOH/g for fillet type (F-type), "two divide" type (T-type) and whole type (W-type), respectively, and the peroxide values were 51.6, 51.5 and 53.2 meq/kg for each. There was a positive correlation between the acid value and the peroxide value (r=0.555) at confidence intervals (CI) of 99%. Trimethylamine (TMA) content of F-type, T-type and W-type products were 2.9, 2.6 and 3.6 mg%, respectively, while volatile basic nitrogen (VBN) contents were 22.4, 21.5 and 21.8 mg%. There was a strong positive correlation between TMA and VBN (r=0.961) at a CI of 99%. The histamine content was detected to be as much as 122 mg/kg, with about 36 % of the samples exceeding the CODEX criteria for histamine of 100 mg/kg. The total microbial count of 4 products exceeded 5 Log CFU/g and coliform group of 11 products exceeded the criteria of less than 1 Log CFU/g. Staphylococcus aureus in 27% of the samples exceeded the criteria of less than 2 Log CFU/g.

Objective: Polycystic ovary (PCO), a diagnostic component of polycystic ovary syndrome (PCOS), requires either an ovarian volume (OV) criterion or a follicle number per ovary (FNPO) criterion. This study investigated the association of OV and FNPO criteria with various manifestations of PCOS. Methods: This cross-sectional study was conducted at a university hospital among 100 patients newly diagnosed with PCOS (according to the revised Rotterdam criteria). Fasting blood samples were collected to measure glucose, total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), lipid, insulin, and hemoglobin A1c levels. An oral glucose tolerance test was performed. Transabdominal or transvaginal ultrasound of the ovaries was done, depending on patients' marital status. All investigations were conducted in the follicular phase of the menstrual cycle. OV >10 mL and/or FNPO ≥12 indicated PCO. A homeostasis model assessment of insulin resistance (IR) value ≥2.6 indicated IR, and metabolic syndrome (MS) was defined according to the international harmonization criteria. Results: Seventy-six participants fulfilled the OV criterion, 70 fulfilled the FNPO criterion, and 89 overall had PCO. Both maximum OV and mean OV had a significant correlation with TT levels (r=0.239, p=0.017 and r=0.280, p=0.005, respectively) and the LH/FSH ratio (r=0.212, p=0.034 and r=0.200, p=0.047, respectively). Mean OV also had a significant correlation with fasting insulin levels (r=0.210, p=0.036). Multivariate binary logistic regression analysis showed that IR (odds ratio [OR], 9.429; 95% confidence interval [CI], 1.701 to 52.271; p=0.010) and MS (OR, 7.952; 95% CI, 1.821 to 34.731; p=0.006) had significant predictive associations with OV alone, even after adjustment for age and body mass index. Conclusion: OV may be more closely related to the androgenic and metabolic characteristics of PCOS than FNPO.

The critical condition of the onset of buoyancy-driven convective motion of uniformly heated horizontal fluid layer was analysed by the propagation theory which transforms the disturbance quantities similarly. The dimensionless critical time, $\tau$$\sub$c/, is obtained as a function of the Rayleigh number and the Prandtl number. Based on the stability criteria and the boundary-layer instability model, a new heat transfer correlation which can cover whole range of Rayleigh number was derived. Our theoretical results predict the experimental results quite reasonably.

A total of 20 soybean recommended varieties which were developed until late 1980's in Korea was evaluated at Suwon. Comprehensive evaluation and correlation analysis were conducted on the agronomic characters. Great variations were found in these genotypes for branch number, pod number, and grain yield per plant. The variation in number of pods/plant ranged from 53 to 164, and in grain yield from 25.9 to 68.8 g. The coefficient of variation for most of the characters had a wide range. In correlation coefficient, grain yield per plant showed a positive phenotypic association with weight of pods, pod number of branches, and weight of stem. Multiple regression analysis was done to formulate selection criteria. It indicated that stout and medium-stature genotypes with more branches, resulting in varieties with more pods per plant but with medium-size seeds are available to obtain high-yielding varieties.

Background and Objectives There was no clinical data except literary study on mutual correlation with autistic disorder in Western medical diagnosis and five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in Oriental medical diagnosis. This study was performed to investigate the correlation of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) to the children with autistic disorder and to set the time table for clinical diagnosis of developmental retardation by making a comparative study of normal developmental children so we can treat the children with autistic disorder in good time. Method We made the comparative study of interview sheets recorded by parents of total 163 children who were diagnosed as autistic disorder who visited HaeMa Oriental Medical Clinic with interview sheets recorded by parents of generally accepted normal developmental children(263) and then we took statistics. Results : 1. There was significant correlation with speech and walking among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) in autistic disorder statistically and clinically in comparison with normal children. 2. There wasn't significant correlation with growth time of tooth among five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) on diagnosis of autistic disorder in comparison with normal children. 3. There was significant correlation with retardation of times going to toilet by oneself (it does not consist in five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲).) in both of autistic disorder. Conclusion Autistic disorder was significantly correlated with the faculty of speech(語遲), retardation in walking out(行遲) of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲). We need to concrete the index of diagnosis, because it is so difficult to measure times and register retardation in tooth eruption(齒遲), retardation in hair-growing(髮遲), debility of neck and nape(頭項軟), flaccidity of extremities(手軟) and flaccidity of muscle(肌肉軟). And we can also use times going to toilet by oneself as one of diagnostic criteria because of its significant correlation. It is required to make early diagnosis of five kinds of flaccidity in infants(五軟), five kinds of retardation(五遲) using these criteria, and to treat them early by oriental medicine.

This study was made to find out the relationship between the eating attitude influenced by an eating disorder and nutritional knowledge among 441 female college students. A self-report questionnaire was used, and the summary of the results are as follows : Almost all of the surveyed female college students were in criteria of standard weight, however they regard themselves more obese than what their actual body shape normally shows. The correlation between perceived body shape and the eating attitude influenced by an eating disorder turned out to be high(p<0.001). The significant level of correlation between the perceived body shape and the eating attitude test-26(EAT-26) scores showed much higher than that obtained between actual shape, degree of obesity and eating attitude test-26(EAT 26) scores(p<0.001). There was no significant level of correlation between the defree of obesity and the average score of nutritional knowledge obtained out of the total questionnaire, however it showed significant level of correlation between macronutrient and roughage(p<0.05), fat and calorie requirement(p<0.01). There was significant correlation among perceived body shape, actual weight and eating attitude influenced. by an eating disorder. Thus the correct perception of body shape turned out to be an important factor in obtaining the desirable eating attitude and adequate nutritional knowldege.
