This paper proposes modeling of human behavior and a method of finding irregular human behavior. At first, human behavior model is proposed by paying attention to habitual human behavior at home. Generally, it is difficult to obtain the information of individual life pattern because of high cost for setting sensors such as cameras to observe human action. Therefore we capture turning on/off consumer electronic equipments as actual human behavior action, where some or many consumer electric equipments were used such as television, room light, video and so on in our daily life. Noting that are some relations between turning on/off those consumer electric equipments and our action, we proposes how to construct a human behavior knowledge by analyzing human behavior based on observation of human habitual life. Also an algorithm to identify on find irregular behavior different from habitual life behavior are described. Finally, the significance of the proposed method is shown by some experimental results.

Background: Stroke patients exhibit arm global synkinesis (GS), involuntary movement due to muscle weakness and irregular muscle tension. But currently there are few studies examined the effects of GS on activates of daily living in stroke patients. Objectives: To investigate the effects the effects of task-oriented bilateral movements, which promote brain plasticity and are based on neurological theory, using the unaffected arm and the affected arm. Design: Quasi-randomized trial. Methods: Twenty stroke patients were randomly assigned to experimental group I (n=10) and experimental group II (n=10). Before the intervention, arm GS was measured using surface electromyography, and the Motor Activity Log evaluated the quantitative and qualitative uses of the affected arm in daily life. The same items were measured four weeks later. Results: The changes in the GS of the arm of experimental group I showed statistically significant differences only in bending motions (P<.05). Both groups showed statistically significant differences in the amount of use (AOU) and the quality of movement (QOM) scores (P<.01). Comparing the groups, statistically significant differences in GS appeared during bending motions (P<.05), and in the AOU (P<.01) and the QOM scores (P<.05). Conclusion: The intervention in GS reduced the abnormal muscle tension of the affected side by increasing the use of the ipsilateral motor pathway, indicating its effectiveness in improving upper limb functions with smooth contraction and relaxation of the muscles.

Arrhythmia is basically diagnosed with the electrocardiogram (ECG) signal, however, ECG is difficult to measure and it requires expert help in analyzing the signal. On the other hand, the radial pulse can be measured with easy and uncomplicated way in daily life, and could be suitable bio-signal for the recent untact paradigm and extensible signal for diagnosis of Korean medicine based on pulse pattern. In this study, we developed an irregular radial pulse detection algorithm based on a learning model and considered its applicability as arrhythmia screening. A total of 1432 pulse waves including irregular pulse data were used in the experiment. Three data sets were prepared with minimal preprocessing to avoid the heuristic feature extraction. As classification algorithms, elastic net logistic regression, random forest, and extreme gradient boosting were applied to each data set and the irregular pulse detection performances were estimated using area under the receiver operating characteristic curve based on a 10-fold cross-validation. The extreme gradient boosting method showed the superior performance than others and found that the classification accuracy reached 99.7%. The results confirmed that the proposed algorithm could be used for arrhythmia screening. To make a fusion technology integrating western and Korean medicine, arrhythmia subtype classification from the perspective of Korean medicine will be needed for future research.

To improve wellness and quality of life by recognizing the health efforts of stress, the author estimated the relationships between stress, subjective symptoms and clinical diagnosis through a questionnaire and a battery of specified laboratory tests; electrocardiography, blood pressure, cholesterol, aspartate aminotransferase(AST), alanine aminotransferase(ALT), gamma glutamyl transferase$(\gamma-GTP)$, fasting blood sugar, gastro-endoscopy or UGI, abdominal sonography, etc. The data was gathered from 337 clients who were undergoing multiphasic screening program at a University Hospital from January to March 1998. The mean age of subjects was $46.5{\pm}11.2$ years and the mean of body mass index was $24.0{\pm}3.7kg/m^2$. The mean vol of stress was $18.5{\pm}6.0$ expressed as the score out of 40. By general characteristics and lift style among male, mean level of stress was significantly higher in case of lower socioeconomic status, habitual drug use, longer daily working time(>10 hours), no regular exercise, drinkers, irregular meal, skip-ping breakfast(p<0.05). In case of female, that was significantly higher in case of lower education, lowe. socioeconomic status, longer daily working time(>10 hours), no regular exercise, drinkers, smokers, irregular meal, skipping breakfast(p<0.05). Significant correlations were observed between stress and subjective symptoms in all kinds of organ system (p<0.01). Correlation coefficients of stress among male were relatively high with neuro-psychiatric symptom$(\gamma=0.476)$ and cardio-vascular symptom$(\gamma=0.361)$ in order, and correlation coefficients of stress among female was highest with neuro-psychiatric symptom$(\gamma=0.371)$. The prevalence of the diagnosis through the battery of laboratory tests was high in upper gastrointestinal disorders and hypercholesterolemia in order in both sex group. Among male the mean score of stress was significantly high in ulcerative peptic disorder of upper gastrointestine and hepatopathy in order (p<0.05) . Among female that was significantly high in diabetes mellitus. In summary, it is likely that there are associations between stress, subjective symptoms and clinical diagnosis. To promote wellness and quality of life it would be of value that periodic stress evaluation program and stress management including apropriate control of smoking and drinking, regular exercise and meal.

The purpose of this study was to investigate the dietary behaviors, eating habits, and nutrient intakes of elementary students with atopic dermatitis. Dietary conditions during infancy, dietary regularity, dietary behaviors, eating habits, and daily nutrient intakes were surveyed and compared between children with (WAD) and without (WOAD) atopic dermatitis using the 24-hr recall method. The ratio of children who responded 'I eat regular meals' was significantly lower in the WAD compared to WOAD group (76.4% vs. 81.7%, p<0.05). The ratio of children who answered 'I eat processed foods or fast foods more than once a week' (p<0.01) and 'I take nutritional supplements' (p<0.001) was significantly higher in the WAD compared to WOAD group. The scores for 'I eat milk and its products everyday' (1.4 vs. 1.5, p<0.05), 'I eat dishes fried or stirred with oil more than twice a week' (2.0 vs. 2.1, p<0.05), and 'I eat snacks such as ice cream, cake, snacks, carbonated beverages more than twice a week' (1.9 vs. 2.0, p<0.05) were significantly lower in the WAD group than in the WOAD group. Daily energy intakes were 1,859.1 kcal and 1,829.5 kcal in WAD and WOAD children, respectively, with no significant difference. However, daily intakes of fat (p<0.05), phosphorus (p<0.05), and vitamin $B_2$ (p<0.05) in WAD children were significantly higher than in WOAD children. To sum up, elementary students with atopic dermatitis had irregular eating habits and higher intake frequency of processed or fast foods, milk and its products, dishes fried or stirred with oil, and snacks compared to normal children. Dietary guidance and nutritional education are required to improve irregular eating habits and induce adequate nutrient intakes in children with atopic dermatitis.

The ultrastructure of damaged hair shaft from blow-drying at typical temperature $40{\sim}170^{\circ}C$ for daily beautiful face have been investigated by using transmission electron microscope and scanning electron microscope. When we used to hair dryer for a long time in our everyday life, the following morphological alternations were found in hair. First, the partial of scales in outer cuticle were detached simultaneously with separation of intercellular membrane complex of cuticle cells. Then hair broke cuticle off and exposed to cortex. Secondly, the cortical cell in the cortex was fissured into its macrofibril. The melanin granules were scattered between macrofibrils. As a result, I confirmed that blow-drying removed the hair's bonded water and made hard on hair which lost elasticity. After all, hair showed irregular, rough surface and vanished its luster.

Middle and high school girl students' menstruation characteristics, appearance of menstruation dysmenorrhea, and coping with the menstruation dysmenorrhea were examined in order to give information in instructing girl students about menstruation dysmenorrhea, in delivering health education in the school, and establishing health policy. 970 girl students in middle and high schools in Cheju-do were selected and surveyed using the questionnaire the author developed based on the previous studies. The findings are as follows. First, the age of first menstruation was average $12.9{\pm}1.22$ years. The younger they were, the earlier their first menstruation came. The most common menstrual cycle was such one that continuously irregular from the beginning or that regular and irregular cycle run together. The first irregular menstrual cycle changed regular one within 1 or 2 years. Most of the respondents had normal menstrual cycle of $21{\sim}35$ days and menstruation period of $3{\sim}8$ days. Second, symptom of menstruation dysmenorrhea was orderly; hurt in the underbelly, tired, hurt in the waist, and headache. It was higher with high school students than middle school students. For the most part, time of heavy menstruation dysmenorrhea was the 2nd day after menstruation starts and period of menstruation dysmenorrhea was 2 days. More than the half of the respondents felt that the present menstruation dysmenorrhea was similar with the first one and they felt not comport in daily life due to menstruation dysmenorrhea, and 'hard to live a normal life' was higher with the high school girl students than with the middle school students. Third, how to cope with menstruation dysmenorrhea was enough sleep, relax and rest, taking a hot water shower, listening to music or watching a movie, taking medicine, and doing excercise. Few of the respondents have ever visited a doctor due to menstruation dysmenorrhea, and the reason was mostly irregular menstruation and heavy dysmenorrhea. Forth, when they took medicine due to menstruation dysmenorrhea, they gathered information on the medicine from family members and friends, while extremely low from a pharmacist or a doctor. The most of them have ever took medicine during menstruation once and took standard dose. While excess dosage was higher with high school students than with middle school students. From these findings, a good many girls are experiencing menstruation dysmenorrhea since their first menstruation. To discover early the severely abnormal findings and to treat, more interest from home and school, counseling and sexual education on time, and expert's diagnosis are necessary. Rather than unconditionally taking pain-relievers which can plainly solve the pain, continuous health education at home and in the school should be carried on for the girls to practice proper measures one think effective or an expert recommends.

The purpose of this study is to improve the method of evaluating groundwater recharge by using grid-based soil moisture routing technique. A model which predicts temporal variation and spatial distribution of soil moisture on a daily time step was developed. The model uses ASCII-formatted map data supported by the irregular gridded map of the GRASS(Geographic Resources Analysis Support System)-GIS and can generate daily and monthly spatial distribution map of surface runoff, soil moisture content, evapotranspiration within the watershed. The model was applied to Ipyunggyo watershed($75.6\;\textrm{km}^2$) located in the upstream of Bocheongchun watershed. Seven maps; DEM(Digital Elevation Mode]), stream, flow path, soil, land use, Thiessen network and free groundwater level, were used for input data. Predicted streamflows resulting from two years (l995, 1996) daily data were compared with the observed values at the watershed outlet. The results of temporal variations and spatial distributions of soil moisture are presented by using GRASS GIS. As a final result, the monthly predicted groundwater recharge was presented.sented.

Purpose: This research is performed through the analysis of the dental technology students' life-style factors of their daily lives that have a close relation with health, and the self-reported symptoms which are related to psychosomatic diseases, for the production of basic data for the change of life-styles and the development of educational programmes. Methods: This research has been performed through questionnaires from the beginning of October of 2014 till the end of November through the Dental Technology students of G-do, chosen by random sampling method after informed consent, where out of the 270 papers, 258 results were used for the analysis. Results: Firstly, the results of the research was as follows: Non-smokers accounted for 61.2%, student who did not do regular physical activities accounted for 50.4%, students who had sleeping hours of 6 to 7 hours accounted for 35.7%, students who eat snacks accounted for 63.2%, students who eat breakfast once to twice a week accounted for 30.6%, students who had an average number of drinks of once to twice a week accounted for 39.9%, and students with BMI of '$18.5^{\circ}{{\neq}}22.9$' accounted for 56.2%, being the highest. Secondly, in gender, smoking (p<.001), regular physical activity (p<.001), BMI (p<.001), eat snacks (p<.05), average number of drinks (p<.05), and of the health check-up, eat breakfast (p<.05), of the year level, eat snack (p<.01), BMI (p<.01), hours of sleep (p<.05), of major satisfaction, regular physical activity (p<.01), and BMI (p<.05), and there was a significant statistical difference, but there were no significant statistical difference in religion. Thirdly, of the bodily self-reported symptoms of the correlation analysis within the life-style variables and the self-reported symptoms, multiple subjective symptoms (I), respiratory (A), eye and skin (B), and digestive organs (C) were the highest in the correlation analysis with regular physical activity (p<.01), and of mental health, impulsiveness (H), mental instability (J), and depression (K) showed highest results in correlation analysis with regular physical activity (p<.01, p<.05), lie scale (L) and irregular and life (G) with eat breakfast (p<.01), and aggressiveness (F) with BMI (p<.01), showed highest results in correlation analysis. Fourthly of the Dental technology students' bodily self-reported symptoms, life-style factors which had a statistically significant effect appeared to be regular physical activity (p<.001) and BMI (p<.05), and of the mental self-reported symptoms, causes that did not have statistically significant effect appeared to be regular physical activity (p<.05) and eat breakfast (p<.05). Conclusion: This research concludes that in order to develop correct life-style habits for health promotion and reduce self-reported symptoms related to the Dental Technology students' diseases, education for the recognition of the necessity of self health promotion must be conducted, and a education programme scheme for the Dental technology curriculum for practicing the correct life-style habits in daily life is required.
