The present study aims at developing standardized patterns of ready-made Korean traditional costume for women in twenties and at suggesting classified standards so that consumers can buy high quailty clothes easily without dissatisfaction on unsuitable measurments. It was found from the dressing experiment results that new-concept patterns of Korean jackets onsidering women's bodies were seriously required because jackets fabricated by conventional patterns were not properily fitted to their bodies. During the processes of patten development, dressing experiment, and subsequent pattern adjustment, measurment standards classified by women's bodies were established, and new standardized patterns were developed in accordance with characteristics of women's bodies. These findings suggested that future studies on the pattern modification should be achieved continuously in consideration of ages, tastes, and fashions of modern women consumers.

The purpose of this study is to find differences in dietary patterns through menu analysis by economic status. The data was obtained from the 1998 and 2001 National Health and Nutrition Survey of Korea. The main variables were economic status, sex, and area by urbanization. The economic status was classified into low, middle, high, and top classes using a poverty line based on the 1998 and 2001 minimum standard cost of living. The areas were divided into metropolis, small city, and rural areas. The dishes of 3 meals were classified into 29 categories by cooking method. The most frequent pattern was "rice + soup + kimchi". The frequency of this Korean basic dietary pattern was the lowest in the top income class and metropolis areas, while the highest in the low income class and rural areas. The frequency of Korean recommended dietary pattern, that is, "rice + soup or stew + kimchi + side dish" was the highest in the top income class. The metropolis group preferred side dishes using meat and a cooking method that saved time, but the rural group preferred side dishes using vegetables and cooking methods that take a longer time. In comparison of dietary pattern between male and female by economic status, the higher economic status, the male's dietary patterns showed more side dishes than those of female. But the main side dish was kimchi in male low class. Consequently, the major dietary pattern in Korea is rice-style, though the western pattern is increasing in the top income class, especially in metropolis areas. Therefore, to make a better dietary pattern, we should develop and spread low-priced recipes of various side dishes and teach financial skills such as ability to make a food budget for lower income classes. Also, we should emphasize the importance of the balance between meat and vegetables and traditional diet and western diet for the top income class, especially in the metropolis areas.

It is well known that tire tread pattern has much influence on the tire pattern noise. The paper describes the method of pattern noise reduction by using the pitch sequence, both on the smooth asphalt roads and on the trenched concrete roads. The noise of tire is classified as either airborne or structure borne noise. Pattern noise through the airborne is considered as a major noise source at high speeds. As block impacting and air pumping by tread patterns are major noise source, tire pattern noise can be greatly influenced by optimal pitch sequence. The goal of this paper is to provide tire engineers with pitch sequence to reduce pattern noise effectively.

Protective coveralls are very uncomfortable to work in comparison to ordinary top and bottom separated clothing. A pattern maker has to consider the size of the human body and human motion range when designing protective coverall patterns. It is difficult to produce well-fitted coveralls because of the lack of readymade patterns despite the increased need for protective coveralls at various jobs. Patterns are decomposed by unsewing 18 products in the domestic market to provide the fundamental information on developing patterns for protective coveralls. The characteristics and differences of pattern types are compared after grouping patterns with information taken from the analysis of the shapes and measurements of patterns from the acquired patterns. The results of the analysis showed that on-market protective coveralls were less curved but much linear when compared to ordinary clothing patterns; however, the breasts and crotch circumferences were very loose and bulky, which is quite different from the other all-in one style working clothes. For the pattern shapes, patterns are classified into waistline-seamed and bustline-seamed types. The result of the hierarchical cluster analysis with 27 measurement variables were classified into four groups. Types by shape and measurements were related to each other; therefore, we expect the information of each type to be used in developing protective clothing patterns.

Purpose: Oral lichen planus (OLP) is relatively common mucosal disease in clinical dentistry. OLP is intractable and regarded having malignant potential. Until now, there is some debate on how far OLP can be malignant, and which characteristics can be a risk factor for malignant transformation. Clinician need to know some differences between OLP and lesions similar to OLP to manage properly and suppose prognosis correctly. Therefore, the aim of this study was to divide clinical OLP into two groups and to compare the results of direct immunofluorescence (DIF) between two groups. Methods: This study was conducted on outpatients who visited at the department of Oral Medicine in Chonbuk National University Hospital from January 2007 to November 2015. Patients with DIF result were retrospectively reviewed. The selected patients were classified 'clinical typical of OLP' (CTO) or 'clinical compatible with OLP' (CCW) by modified World Health Organization diagnostic criteria of OLP and oral lichenoid lesion. Results: DIF were classified by deposition intensity or pattern of anti-human antibody and fibrinogen. The classification of fluorescence pattern in each specimen was graded as positive, possibly positive or negative. Conclusions: Both CTO and CCW had positive and possibly positive pattern. Prevalence of positive pattern was 68.8% in CTO and 52.6% in CCW and that of possibly positive pattern was 9.4% in CTO and 5.3% in CCW. Prevalence of negative was 21.8% in CTO and 42.1% in CCW.

In this research, I classified adult women's back types through anthropometric measurement and photographic measurement to present a judging individual body size according to the type. Also, Ⅰ calculated regression fomula by types and presented the basic bodice pattern. The results were as follows: 1. The result of factor analysis indicated that 5 factors were extracted and those factors comprised 75.89% of total variance. 2. According to the cluster analysis, Ⅰclassified the back types into 6 types. Type 1 was passive posture in the upper and the lower parts of the back. Type 2 was active posture in the upper and the lower parts of the back. Type 3 had the lowest protrusion of the back. Type 4 had the upper part of the back which is mostly bent downward. Type 5 was the most suitable shape. Type 6 had the lower part of the back which was turned over the most. 3. Ⅰconducted a discriminant analysis to judge the body types of individuals. 4. For the calculation of measurements necessary for the basic bodice pattern, Ⅰpresented regression formulas by each type. 5. By conducting the wearing experiments, Ⅰsuccessfully made the final basic bodice patterns by types. As a result of comparative experiments between the basic bodice patterns and comparison bodice pattern, the suitability of basic bodice patterns were more highly assessed.

Objectives : This study was performed to investigate characteristic indice of heart rate variability (HRV) according to presence of metabolic syndrome (MS), pattern identification. Methods : We analyzed 167 subjects who participated in a stroke check-up. We classified the subjects into two groups as MS (n=48) and non-MS (n=119) based on NCEP ATP III. First, we investigated pattern identification of all subjects based on Korean Standard Pattern Identifications for Stroke-III. Second, we surveyed significance of HRV indices between MS and non-MS groups. Third, we investigated significance of HRV indices between classified DP of MS and classified DP of non-MS. Fourth, we investigated significance of HRV indices between classified DP of MS and non-MS. Fifth, we investigated significance between components of MS and HRV indices. Results : 1. SDNN, RMS-SD, HF, Ln(HF), and HF (NORM) were significantly lower in the MS than non-MS group. LN (TP), LF/HF were significantly higher in the MS than non-MS. 2. Ln (HF), Ln (TP), and LF/HF were statistically significant in the classified DP of MS group. 3. RMS-SD, and Ln (HF) were significantly lower in the abdominal obesity group than in the non-abdominal obesity group. SDNN, RMS-SD, TP, Ln (TP), VLF, Ln (VLF), and Ln (LF) were significantly lower in the hypertension group than in the non-hypertension group. RMS-SD was significantly lower in the diabetes group than in the non-diabetes group. Mean HRT,LF/HF were significantly higher in the hypertriglyceridemia than non-hypertriglyceridemia group, but Ln (HF), RMS-SD, and HF (NORM) were significantly lower in the hypertriglyceridemia than non-hypertriglyceridemia group. Conclusions : We found a few significant relationships between classified DP of MS and HRV indices. The resluts demonstrate that MS has potentially negative effects on the cardiovascular system, and these effects could be detected by HRV.

The purpose of this study was to develope a pattern drafting method for various somatotype which contribute largely to increase the fitness and comfort of garments. This study had 8 subjects who were college girls who had prominent somatic characteristics. The study was carried out by the following procedures. 1. The 8 subjects who had prominent somatic characteristics were cheesed by photograph- ing. The somatotypes of 8 subjects were classified into Standard somatotype, Turning over somatotype, Bending somatotype and Turning over-Bending somatotype. 2. Under the criterion of the body surface development, the comparative investigation on the pattern and the sensory evaluation were accomplished in the flat pattern method and the draping pattern method. 3. The body surface development of them were made by the draping pattern method. 4. In the result of the comparative investigation and the sensory evaluation, it was found that the flat pattern had better appearance and comfort than the draping pattern, and the draping pattern included more somatic characteristics than the flat pattern. 5. On the basis of those result, the pattern drafting method according to the somatotype was indicated and it was examinated by the clothing experiment. 6. The sensory evaluation for appearance and comfort was applied to evaluate the new basic pattern for four somatotype by comparing it with the conventional basic pattern (Rim, won ja' 5). The result of the sensory evaluation, it was found that the new basic pattern was more suitable for each somatotype than the conventional basic pattern.

We propose a new content-based image retrieval using a block color co-occurrence matrix (BCCM) and pattern correlogram. In the proposed method, the color feature vectors are extracted by using BCCM that represents the probability of the co-occurrence of two mean colors within blocks. Also the pattern feature vectors are extracted by using pattern correlogram which is combined with spatial correlation of pattern. In the proposed pattern correlogram method. after block-divided image is classified into 48 patterns with respect to the change of the RGB color of the image, joint probability between the same pattern from the surrounding blocks existing at the fixed distance and the center pattern is calculated. Experimental results show that the proposed method can outperform the conventional methods as regards the precision and the size of the feature vector dimension.

Texture is one of the important characteristics that has been used to identify objects or regions of interest in an image. Tire tread patterns can be considered as a kind of texture, and these are classified with a texture analysis method. In this sense, this paper proposes a new algorithm for the classification of tire tread pattern. For the classification, cooccurrence matrix for the binary image is used. The performances are tested by experimentally 8 different tire tread pattern and the robustness is examined by including some kinds on noise.
