An attempt was made to study the subdivision of Korea by the annual amount and the annual change pattern of monthly precipitation days(that is one of the important elements of the precipitation characteristics), using the mean values for the years 1961-1990 at the 68 stations. The amplitudes of annual change were normalized and using these values, the principal component analysis was applied to determine the annual change patterns. The results show that they are expressed by the combinations of the three change patterns in almost whole regions of Korea. As a result,the annual change pattern of precipitation days in Korea is classified into 8 types from A to e,in detail, 36 types from A0 to e$\circled2$.And regional division of precipitation days in Korea is divided into 13 regions from I a to IIIC,into detail, 41 regions from I no to IIICl.

This study analyzed the "research trends and the design processes" of the traditional patterns by examining the previous researches on the application of the traditional patterns. For this purpose, 96 studies which include master's and doctoral theses and research papers published in 8 Korean academic journals on Clothing from 2000 to 2010 were chosen. The findings of this study are as follows: First, when the previous researches on the application of the traditional patterns were classified according to their subject matter, they were classified into: research on clothing design, research on textile design, research on the design of cultural commodities, and research on mixed design. Second, the researches that were classified according to their subject matter were re-classified according to their year of publication. It was shown that the most active research was on the clothing design. The research on textile design, when compared with clothing design, alternated an increase and an decrease in every other year. Also, research on the design of cultural commodities were fewer than the research on clothing design or textile design although it is on the increase from 2008. Third, when classified according to the types of design, it was found that the designs based on a flora were most common. Fourth, in most cases, in the process of the designs, the designswere dispensed with the original form or were simplified. The choice of the tone of color, in most cases, were based on the concept selected by the designer. The most common method for the expression of the designs was based on the printing. Also, when it came to the presentation of the designs, the original work greatly outnumbered an imaginary work. Based on this study, it is hoped that there will be more active research on the application of the traditional designs which, in turn, can popularize the aesthetic beauty of Korea.

Background : Osteoporosis and atrophic cell pattern in Pap smear are frequent findings In postmenopausal women due to loss of ovarian function, The present study attempted to find out possible correlation between morphologic characteristics of Pap smear and osteoporosis. Material & methods: The subjects were 825 women(age from 35 to 80) who had undergone Pap smear and bone mineral density(BMD) at The Korea Association of Health Promotion, Seoul Branch, from March 8 to May 10, 2005. Pap smears from 825 women were reviewed and classified either mature cell pattern or atrophic cell pattern by their cytologic patterns, BMD were measured using LUNAR DPX MdIQ(Minster, Ohio, USA). BMD value of lumbar spine(Ll, L2,L3 and L4) were measured from 825 women and BMD value of proximal region off emur(neck NK, Wards triangle WT, and trochanter TR) were measured from 818 women and their bone status were classified as normal( T-sore:>-1.0), osteopenia (T-score: -l~<-2,5) and osteoporosis(T-score: ≤ -2.5). And age distribution of Pap smear, average T-value andfrequency ofsteoporo-sis of each region of the bone, percentage of osteoporosis of each boneregion by age group and changing pattern of percentage of osteopenia and osteoporosis in certain postmenopausal period were compared between mature and atrophic cell pattern. Results: Pap smears revealed total mature cell pattern 53,9%(445/825) and total atrophic cell pattern 46.1%(380/825), Percentage of mature cell pattern decreased from 98.2%(168/171)under 44 age group to 13,3%(17/128) over 65 age group and mature cell pattern increased from 1.8%(3/171) under 44 age group to 86.7%(111/128) oyer 65 age group. Mean T-value of each region of lumbar spine and femur of mature cell pattern were lower than that of atrophic cell pattern about -1,5. And osteoporosis has noted in atrophic cell pattern showing odds ratio Ll 13.9, L2 15.3, L3 12.0, L4 10,4, UK 6.7, WT 10.9 and TR 4.1.Atrophic cell pattern started to increase after 45 years of age and osteoporosis of a trophic cell pattern started after 55 years of age. During 50 to 64 years of age period, L3, L4 and WT revealed parallel increased of osteopenia and osteoporosis and Ll, L2 revealed decreased of osteopenia and increased of osteoporosis. nia Conclusion: Above findings suggest that atrophic cell pattern of Pap smear precedes osteoporosis about 10 years and one of predictor of osteoporosis.

This article is a study on to which categories of modern diseases qi deficiency pattern types are assigned by reference to modern clinical papers to analyze and understand modern diseases with the perspective of Korean Medicine. Clinical papers were searched in China Academic Journals(CAJ) of China National Knowledge Infrastructure(CNKI) from 1994 to 2013. Conclusions are as follows. First, qi deficiency pattern types are roughly classified as qi deficiency pattern, qi-yin dual deficiency pattern and qi deficiency pattern related with viscera and bowels. Second, there are many patterns combined with static blood, qi stagnation, phlegm, dampness, heat, toxin, water or fluid deficiency and the level of pattern designation is more specific than pattern types in Korean Standard Classification of Diseases(KCD), which makes the pattern types more useful to clinical application. Third, static blood due to qi deficiency is the most frequent combined pattern and diseases related with blood circulation such as angina, atherosclerosis, hyperlipidemia and chronic obstructive pulmonary disease(COPD) were reported on that pattern. The detailed relation between modern diseases and pattern types can be an another topic.

Objectives : We performed a clinical study to investigate autonomic conditions in persistent allergic rhinitis depending on various pattern identifications and the availability of heart rate variability (HRV) as a pattern identification diagnostic tool. Methods : 32 patients with persistent allergic rhinitis were asked to interview with doctor of Korean Medicine and perform the four pattern questionnaires (Cold-Heat Pattern, Phlegm Pattern, Yin Deficiency pattern, bloodstasis pattern). Then, they were examined their autonomic conditions with heart rate variability test. Results : Patients were classified as three pattern groups (Lung-stomach heat, Lung qi deficiency cold, Lung-spleen qi deficiency) by doctor. In the Lung qi deficiency cold group, Total power of the HRV (TP) and the power of the low frequency component (LF) significantly higher than in the Lung-stomach heat or Lung-spleen qi deficiency group (P < 0.05). Also, Patients were classified as 8 pattern groups (Cold/Heat, Phlegm/Non-phlegm, Yin deficiency/Non-yin deficiency, Bloodstasis/Non-bloodstasis) by four pattern questionnaires. Only in the Yin deficiency group, the power of the low frequency component (LF) significantly lower than in the Non-yin deficiency group (P < 0.05). There were not any significant differences in the rest groups. Conclusions : The result may provide that HRV doesn't reflect well the differences in the various pattern groups, and the HRV's availability is low. Continuous studies are needed to develop the objective and standardized pattern identification diagnostic tool for allergic rhinitis.

In this paper, pattern recognition scheme for EMG signal using artificial neural network is proposed. For manipulating ability, the movements of human arm are classified into several categories EMG signals of appropriate muscles are collected during arm movement. Patterns of EMG signals of each movement are recognized as follows: 1) The features of each EMG signal are extracted. 2) With these features, the neural network is trained by using feedforward error back-propagation (FFEBP) algorithm. The results show that the arm movements can be classified with EMG signals at high accuracy.

Preserving image features, edges and details in the process of impulsive noise filtering is an important problem. To avoid image blurring, only corrupted pixels must be filtered. In this paper, we propose an effective impulse noise detection method using Self-Organizing Neural Network(SONN) which applies median filter selectively for removing random-valued impulse noises while preserving image features, edges and details. Using a $3\times3$ window, we obtain useful local features with which impulse noise patterns are classified. SONN is trained with sample image patterns and each pixel pattern is classified by its local information in the image. The results of the experiments with various images which are the noise range of $5-15\%$ show that our method performs better than other methods which use multiple threshold values for impulse noise detection.

This study analyzed the shot pattern through the tempo of segmented shot duration and studied the relationship with the unique emotion of the story. The structure of the story was classified into 3 chapters, 17 sequences, 83 scenes, 287 beats, and 1636 shots. Shot density is a method of visualizing tension in visual storytelling, and since it is a result obtained by mathematically calculating the density of divided shots, it can be helpful in designing tension delivered to the audience. Nine shot density patterns were extracted. The ascending(+) type was classified as A, B, C, D, 4, the descending(-) type, E, F, G, H, 4, and the maintenance(/) type, I, 1 type. Based on the spatiality of the 17 stages of Campbell's heroic narrative and McGee's story structure, the narrative level of the tree structure was proposed, and the symbolic meaning of the shot rhythm in the practical aspect of the story function was proposed to present a systematic methodology in the direction of production.
