The objectives of the thesis are to propose a pattern classification method for remote sensing data using artificial neural network. First, we apply the error back propagation algorithm to classify the remote sensing data. In this case, the classification performance depends on a training data set. Using the training data set and the error back propagation algorithm, a layered neural network is trained such that the training pattern are classified with a specified accuracy. After training the neural network, some pixels are deleted from the original training data set if they are incorrectly classified and a new training data set is built up. Once training is complete, a testing data set is classified by using the trained neural network. The classification results of Landsat TM data show that this approach produces excellent results which are more realistic and noiseless compared with a conventional Bayesian method.
Objective : This study aimed to report the improvement of two patients with headache not otherwise classified treated using Saengkangsasim-tang based on the disease pattern identification diagnostic system (DPIDS) based on the Shanghanlun provisions. Methods : Two patients with headache not otherwise classified were treated using Saengkangsasim-tang according to Shanghanlun provisions, and the effect was also compared with Soshiho-tang. The results were evaluated using a numerical rating scale (NRS) and the Korea Headache Impact Test-6 (KHIT-6). In addition, new clinical implications for the interpretation of Shanghanlun provision 157 were reviewed. Results : As a result of analyzing the results of the two cases, treatment with Sosiho-tang was ineffective but improved when using Saengkangsasim-tang. After administration of Saengkangsasim-tang, all headaches decreased to the point where they were not uncomfortable in everyday life. Conclusions : The administration of Saengkangsasim-tang to patients with headache diagnosed according to Shanghanlun provision 157, suggesting that it is clinically effective when applied according to the definitions provided by the Shanghanlun provisions.
The purposes of this study were to investigate used patterns in Hanbok and to find out a classification and a characteristic of motifs. The data made use of 111 pictures constituted Gegory(a Korean jacket) and Chima(a skirt) in photographs collected in wedding magazine(Wedding 21'). The data was analyzed by frequency, contents analysis. Pattern's use or not in Hanbok and a sort, a arrangement, a way of expression of patterns using frequency Classified and characteristics of motifs were analyzed contents analysis. The results of this study were as follows. First, a sort of patterns was lots of flower motifs of the plant pattern. An arrangement of and expression of patterns used mainly a partial arrangement and embroidery expression. Second, the subjects classified using criterion of classification of a external feature, forms of expression, and simplicity/complexity of line. Third, the motifs classified into plants, an animal, geometry, abstraction, and a natural object. The plant motifs were perceived the focus of flower, a combination of a flower and a stem in the plant motifs. The subjects perceived as a simplicity/complexity of flower and a drawing line of a flower and a stem.
This study emphasizes on the characteristics of the excavated fabrics from the tomb of Kimwhoak in the late 16th and early 17th centuries. All of 118 kinds of fabrics are used in excavated costume from the tomb of Kimwhoak. Classified by its materials, it is divided into small groups as follows: 63 pieces of spun silk tabby(53.6%), 14 of spun yarn silk(11.9%), 13 of thin filament silk tabby(11.0%), 8 of thin silk tabby(6.8%), 4 of satin without pattern(3.4%), 3 of filament silk tabby(2.5%), 3 of twill without pattern(2.5%), 2 of satin damask(1.7%), 2 of mixture fabric with silk and cotton(1.7%), and 2 of ramie fabric(1.7%), 1 of simple gauze without pattern(0.8%), 1 of damask with supplementary gold thread(0.8), 1 of cotton(0.8%), 1 of etc(0.8%). Classified by ways of weaving: 106 pieces of plain weave(89%), 6 of satin weave(5%), 3 of twill weave (3%), 1 of gauze weave(1%), 1 of compound weave(1%) and etc(1%). In point of patterns, the most of textiles are without pattern, there are only two of them are patterned textile. such as lotus patterns with vine, peony patterns with vine. Their patterns are very similar to those of other tombs in the same age.
The color overlay pattern of thyroid shear wave elastography applied in this study distinguishes benign and malignant nodules based on the optimal cut-off value of 74.2 kPa. From august 2021 to september 2021, thyroid ultrasound and elastography were performed on 57 patients with thyroid lesions using an ultrasound device RS85 prestige (Samsung Medison, Korea) and a 2-14 MHz linear transducer. In addition, the results of classification by K-TIRADS for each thyroid nodule and the results of classification by color overlay pattern according to the kPa value of acoustic ultrasound were compared and analyzed. In the color overlay pattern, the results classified as 40 people from dark blue to light blue and 17 people from green to red were similar to the K-TIRADS category results, which were classified as 42 benign and 15 malignant. Between blue and light blue, benign, and between green and red, malignant. If the shear wave elastography method is applied before the fine-needle aspiration cytology of the thyroid nodule is performed, the differential diagnosis of thyroid tissue from benign and malignant can be predicted in advance, and it will help to reduce unnecessary invasive tests.
In this paper we introduce a new prototype based classifiers for overlapping data, where training pattern can be overlap on the feature space. The proposed classifier is based on the prototype from neural network classifier (NNC)[1] for overlap data. The method automatically chooses the initial center and two radiuses for each class. The center is used as a mean representative of training data for each class. The unclassified pattern is classified by measure distance from the class center. If the distance is in the lower (shorter radius) the unknown pattern has the high percentage of being in this class. If the distance is between the lower and upper (further radius), the pattern has the probability of being in this class or others. But if the distance is outside the upper, the pattern is not in this class. We borrow the words upper and lower from the rough set to represent the region of certainty [3]. The training algorithm to find number of cluster and their parameters (center, lower, upper) is presented. The clustering result is tested using patterns from Thai handwritten letter and the clustering result is very similar to human eyes clustering.
The purpose of this study was to fad the specific character of menu patterns by sex, age and health risk of subjects for the basic data of a nutrition education program. The dietary intake of the subjects was investigated by the 24-hour recall method. Subjects consisted of male 94, female 394, total 488. To analyze patterns, dishes were classified into major staple foods ; kimchi, soup and side dishes and also classified into 24 categories by the cooking method. For the men, a frequently served pattern was cooked rice + soup + kimchi. For the women, the pattern was also cooked rice + soup + kimchi. For the 20-49 year olds and the 50-64 year olds, frequently served patterns were cooked rice + soup + kimchi > noodle + kimchi. For the 65-74 year olds, those patterns were cooked rice + stew > cooked rice + kimchi. For the normal group and the risk group, the frequently served pattern was cooked rice + soup + kimchi. The most used menu pattern by the number of dishes was cooked rice + soup + kimchi in the male, female, normal group and risk group. For the 20-49 year olds, the pattern was cooked rice + soup + kimchi and noodle + kimchi. For the 50-64 year olds, it was cooked rice + soup + kimchi. For the 65-74 years old, it was cooked rice + stew. The result of analyzing patterns for the most used main staple food was cooked rice in all groups. The results of analyzing patterns, with those considered basic food, cooked rice, soup and stew, showed that frequently served patterns were cooked rice + soup > cooked rice > cooked rice + stew in all groups. With these results, we can summarize that the menu patterns of people in Kangbukgu was the younger, the more non-traditional. Also, the normal group had more various patterns than those of the risk group. Thus, we need further research about menu patterns to provide adequate nutrition education.
Objectives This research was proposed to present Clinical Practice Guideline (CPG) for Prevention of Sasangin disease pattern of Sasang Constitutional Medicine (SCM) and diseases closely related with Sasang constitution. Each CPG was developed by the national-wide experts committee consisting of SCM professors. Methods At first, we searched the literatures related to SCM such as "Dongeuisusebowon", Textbook of SCM and Clinical Guidebook of SCM. Also we searched the articles related to the studies about risk factors for Sasangin disease pattern of both at home and abroad. Finally, we selected leading risk factors of Sasangin disease pattern and developed CPG for prevention of Sasangin disease pattern of SCM. And then, we searched the literatures related SCM such as "Dongeuisusebowon" and the articles on the correlation between disease and Sasang constitution using case-control studies, observational studies or cross sectional studies of both at home and abroad. Next, we selected diseases closely related with Sasang constitution on the basis of articles including prevalence rate and odds ratio between disease and Sasang constitution and finally developed CPG for these diseases. Results and Conclusions We categorized risk factors of Sasang disease pattern into 2 types: non-modifiable and potentially modifiable. 3 items (age, sex and genetic factors) were classified as non-modifiable risk factors of Sasang disease pattern. 6 items (original symptom, stress, diet and nutrition, physical activity, alcohol and drug misuse) were classified as less well-documented or potentially modifiable risk factors of Sasangin disease pattern. We found out Sasang constitution is more likely to develop some diseases. It was proven that Sasang constitution increase the risk of hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. And there is high probability of Sasang constitution being potential risk factor for obesity, hyperlipidemia, allergy and cancer. Also, we found out Taeeumin is independent risk factor for hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. Therefore we recommend that Taeeumin need to prevent these disease by regular checkups and aggressive management.
The purpose of this study was to examine patterns ofmoney management and control of family finances. The data for this study were collected from 311 wives who were currently employed in professional, managerial, and clerical occupation living or employed in Seoul. Frequency, percentage and cross-tab analysis were used to analyze the data. The results were as follows: 1) money management patterns were classified into six types; wife-management pattern, wife-management/husband-alienation pattern, wife-management/husband-involvement patter, joint management pattern, joint/separate mixed pattern, and multi management pattern. Among them wife-mannagement pattern was used most frequencly by the couples. 2) Four family finance control patterns were found and named by joint control, wife control, husband control, and self control. The joint control pattern was found to be the most prevalent one. 3) Money management patterns influenced how family finances were controled.
The purpose of this study was to determine pattern of the stress perceived by stroke patients over time. The ultimate goal of the research is to provide data to help nurses to design the plan of nursing care of the stroke patients both in the hospital and at home. A total of 57 admitted stroke patients were collected from one general hospital in Seoul from June, 12 to September, la, 1993. The data were collected for three phases(within one week after leaving the hospital). The tools for this study, three scales were used ; Stress scale developed by the investigator. Constitution classifing scale designed by Kho(1984), and Self-care measuring scale by Kang(1984). Data were analyzed in four steps using statistical analysis. First, demographic data were determined by descriptive statistics. Second. the pattern of stress perceived by stroke patients across three phases was measured using repeated measures ANOVA. Third, stress of stroke patients classified by constitution, paralyzed area. and attack frequency were measured using ANOVA or t-test, and the pattern of stress by group over time was determined using paired t-test in post hoc test. Fourth. Pearson correlation coefficients were calculated to determine the relationship between the stress and self-care activities. The results of this study are ; 1. The pattern of stress across three phases ; There was a decrease of the stress across three phases. In general. psychological stress as the highest among three phases(F=36.92. P=.000). There was a statistically significant difference of the physical stress(F=34.55, p=.000), the psychological stress (F=15.49, p=.0005) and the social stress (F=24.71. p=.000) among three phases. There was a statistically significant difference of the stress between the first phase (on admission) and the second phase(before leaving the hospital) and was a decrease of the stress (t =6.36. p=.000). 2. The pattern of stress of stroke patients classified by constitution across three phases ; Stroke patients classified as So-Eum perceived the highest stress among three groups(Tae-Eum, So-Eum. So-Yang). There was no statistically significant difference of stress according to the constitution of stroke patients among three phases. Hence. stress was not influenced by the constitution of stroke patients, but there was a statistically significant difference of stress over time. 3. The pattern of stress of stroke patients classified by the paralyzed area across three phases ; Right paralyzed stroke patients perceived higher stress than left paralyzed stroke patients. There was, however, no statistically significant difference of stress between two groups except 2nd phase. There was no statistically significant difference of the perception of stress bet ween the right and left paralyzed stroke patients. 4. The pattern of stress of stroke patients classified by the frequency of the relapse of the disease across three phases ; Stress was higher in stroke patients who had the relapse of the disease twice more than the first time. There was, however, no statistically significant difference of stress between two groups. There was no statistically significant difference of stress of stroke patients according to the relapse of the disease among three phases. Hence, stress was no influenced by the relapse of the disease. 5. The relationship between the stress and self-care activities ; There was a negative relationship between the stress and self-care activities each phase(on admission, r= -.1563 ; before leaving the hospital, r= -.4030 ; after leaving the hospital, r= -.5291). Hence, the higher the self-care activities, the lower the stress. This study has three important findings. First finding was that psychological stress perceived by stroke patients was the highest among three phases. The second finding was that factors such as the constitution, the paralyzed area, and the relapse of the disease did not have an influence on the stress perceived by stroke patients across three phases(on admission, before leaving the hospital, after leaving the hospital). There was a statistically significant decrease of the stress perceived by stroke patients across three phases. The third finding was that there was a negative relationship between the self-care ability and stress. In this study, these findings have implications for nursing care for the rehabilitation of stroke patients and suggest the need of nursing intervention to promote the self-care ability and to support the psychological self-esteem of stroke patients.
