The purpose of this study aimed to know the association between seven health practices and self rated health by Sasang constitution. We recruited 367 subjects aged from 30 to 59. KS 15 questionnaire was used to classify Sasang constitution and visual analogue scale was used to estimate self rated health. Chi-square test was used to know the difference of occupation distribution by Sasang constitution. Anova test, T-test and Chi-square test also used to analyze the difference of self rated health between the health practice group and non-health group in individual Sasang constitution. SPSS 21.0K was used and significant p was <.05. Regular morning meal, non-snaking, good sleeping and sufficient exercise had higher self rated health score (p<.05). Regular morning meal, good sleeping and sufficient exercise had higher score in Tae-eumin (p<.05). Good sleeping had higher self rated health score in Soeumin and Soyangin (p<.05). These results suggest there is possibility that health practices for health promotion could be different according to Sasang constitution.

Self-controlled permanent magnet synchronous motor (PMSM) has similar operating characteristics as seperately excited dc motor. It is favored in servo applications due to its improvement of efficiency and maintenance. This paper presents completely digitalized controller using microprocessor and voltage fed inverter. The speed control system for PMSM is implemented. To control the motor speed, the control system regulates the magnitude of Inverter output voltage by regular-sampled PWM method to generate sinusoidal PWM wave with microprocessor. And to keep the range of inverter switching frequency, it varies the number of pulse train according to the speed.

The purpose of this study is to analyze the affecting factors on breast self-examination of middle-aged women in Korea. The subjects were 141 women on Jeju Island, and materials were collected through an organized questionnaire from March to August 2002. The data were analyzed by using descriptive statistics, $x^2$-test. A-nova and Discriminant analysis by the SAS program. The major results are as follows: 1. 53% of the subjects performed the breast self-examination. The practice of breast self-examination was correlated with the education level, income, low salt diet, more than 30 minutes of regular exercise. 2. Attitudes towards breast self-examination were not a significant practice regarding breast self-examination. However, the cognition about difficulty of breast self-examination partly showed an important barrier factor to the positive attitude. 3. The average self-efficacy concerning breast self-examination was 3.03. The stages of change related to the subjects showed that a contemplation stage was high. 4. With a stepwise multiple regression, the most significant factor on self-efficacy related with breast self-examination was the contemplation stage, 30-40 aged women. high income, regular exercise, low salt diet, family cancer history, etc. 5. With the discriminant analysis, the most important factors related with the practice of the breast self-examination were income and self-efficacy. The power of discriminant was 59%. The results of this study suggests that programs should be developed to promote practice and the self-efficacy related with breast self-examination.

The purpose of this study was to determine the extent of tooth structure crazing when pinhole were drilled in dentin at various distances from the dentionenamel junction, and when pins were inserted by hand wrench and Auto-klutch handpiece. Sixty freshly extracted teeth were embedded in blocks of cold-curing acrylic resin to a level 1mm apical to the cementoenamel junction, the crown of the teeth were removed to a level 1.5mm coronal to the cementoenamel junction. After being sectioned, the cut surface of the teeth were smoothed, and they were divided into 4 groups. Group I : 4 pinholes were drilled with self-threading Minim spiral drill and pins were inserted with hand wrench in fifteen teeth. Group II : 4 pinholes were drilled with self-threading Minim spiral drill and pins were inserted with Auto-klutch handpiece in fifteen teeth. Group III : 4 pinholes were drilled with self-threading Regular spiral drill and pins were inserted with hand wrench in fifteen teeth. Group IV : 4 pinholes were drilled with self-threading Regular spiral drill and pins were inserted with Auto-klutch handpiece in fifteen teeth. The cut surface were then examined microscopically for the presence or absence of craze line. The results were as follows: 1. The self-threading Minim pin groups (Group I & II) produced less craze lines than did the self-threading Regular pin groups (Group III & IV). 2. In the self-threading Minim pin groups, there was more craze lines with hand wrench (Group I) than with Auto-klutch handpiece (Group 11). 3. In the self-threading Regular pin groups, there was more craze lines with hand wrench (Group III) than with Auto-klutch handpiece (Group IV). 4. Placement of the pinhole at 0.0mm from the dentionenamel junction produced more craze lines than placed at 0.5mm, 1.0mm (p<0.05), however there was no statistically significant between the 0.5mm and 1.0mm distance.

The purpose of this study was to assess the perceived exercise self-efficacy and exercise benefits/barriers of Korean adults with chronic diseases, and the relationship between the two variables. For the study, 249 Korean adults with chronic diseases with ages ranging from 18 to 79 years were recruited from hospitals or health centers in five Korean cities and surrounding rural areas. The research instruments were the scales that researchers psychometrically verified the Exercise Self-Efficacy Scale, developed by Bandura (1997), and the Exercise Benefits/ Barriers Scale, developed by Sechrist, Walker, and Pender(1987). Results of descriptive analysis showed that Korean adults with chronic diseases perceived relatively low exercise self-efficacy and relatively high exercise benefits/ barriers. Exercise self-efficacy was significantly correlated with gender, education, regular exercise, and exercise benefits/barriers was significantly correlated with gender, regular exercise. Pearson correlation coefficient showed the significant relationship between the two variables. Further researches, which are a study to evaluate a causal structure for Pender's Health Promotion Model and an intervention study to increase physical activity of chronic patients, are recommended.

A series of model testes on a container ship in regular were executed. This paper presents the results of resistance, self-propulsion, and ship motion tests. The experimental results of ship motion measured on a towed model and a self-propelled model were compared with those of Japanese's model test showing fairly good agreements. The results of added resistance tests were compared with those of Japanese' model test and also compared with the calculation results by Gerritsma's method showing somewhat large discrepancies at higher speeds. Also the results of added resistance tests measured on a fixed model were compared with the calculation results by Gerritsma's method. Finally the results of self-propulsion tests were presented.

The purpose of this study was to investigate health promoting life-style(HPLS) and its predictors by menstrual status among middle-aged women. The HPLS was conceptualized to have six domains such as self-actualization, responsibility for health, nutrition, exercise, interpersonal relationships, and stress control. Those predictors included three sociodemographic factors and five cognitive factors. Menstrual status was classified into three stages : regular menstrual(premenopausal), menopausal, and postmenopausal stages. Data were collected from 240 women between 30 and 59 years through self-reported questionnaires. Chi-square test, ANOVA, and stepwise multiple regression techniques were used to analyze the data. The results are summarized as follows : 1. The HPLS activities, when aggregated, were not statistically different across the three groups. The activities of the domains of interpersonal relationships and self-actualization were higher then those of other domains. On the other hand, the activities of the domains of exercise and responsibility for health were lower than those of the other domains. 2. The predictors explained 27.2%, 43.8%, and 41.6% of the variance of HPLS in the regular menstrual, the menopausal, and the postmenopausal groups, respectively. 3. In the regular menstrual group, total HPLS was significantly predicted by monthly income, family support, number of family members and education level at the .05 level in the HPLS. 4. In the menopausal group was significantly predicted by self efficacy. 5. The HPLS activities of the postmenopausal group were significantly predicted by family support, self efficacy, and monthly income at the .05 level in the HPLS.

Background: Skin self-examination (SSE) may facilitate early diagnosis of melanoma at a potentially curable stage. Little data are available concerning the SSE frequency and knowledge about the symptoms of melanoma in non-patient populations. The aim of our study was to assess the performance of skin self-examination, recognition of potential melanoma symptoms as well as behavior related to sun exposure among web users in Poland. Materials and Methods: A cross-sectional study was conducted among readers of a scientific portal. Invited respondents were asked to complete an online questionnaire. Finally, statistical analysis was conducted on 4,919 surveys towards potential clinical signs of melanoma and SSE performance. Results: Approximately 60% of respondents had ever performed SSE in their life. Only 18.4 % declared performance on a regular, monthly, basis. Factors promoting this activity were established to be bigger place of residence, higher education and sensitive skin phototype, higher level of knowledge concerning melanoma, safe tanning rules and, especially, past surgical excision of naevi. Declared longer use of tanning beds was linked to understanding better the importance of clinical features of melanoma. Awareness of hazardous behavior during sunbathing is associated with the attempts to change them. Conclusions: Regular SSE is not a common practice, whilst the knowledge about the clinical features of melanoma is varied. Therefore, constant pressure should be put on promotion of regular skin self-examination and teaching its proper techniques, including familiarity with the ABCD (asymmetry; border; color; diameter) rule and its extension of "EFG" (elevated, firm, progressive growth) criteria.
