In this paper, fabricated is a motion capture and attitude detection system for Head Mounted Display HMD composed of three low-price and low-grade micro gyroscopes and a micro-controller, To calculate attitude of a body, modified INS algorithm is used. Because the micro gyroscope has much bias drift error, scale factor error, and run-to-run bias error, the motion of a body can not be measured exactly if the general INS algorithm and micro gyroscopes are used. To reduce the errors, three accelerometers can be used. In this case, however, the size and power consumption become too large to use in HMD system. The modified INS algorithm use the grid map and the characteristics of the human motions.

This study was designed to investigate the role of weight control in the formation of underlying pathology in eating disorder or eating related problems. The subjects were 304 college athletes(Male : 187. Female: 121) and they were divided into two groups according to need for weight control(Weght control group: 110, Weght non control group: 194). The authors used self report questionnaire which was composed of epidemiologic data, food habit scale, eating attitude test, scale for locus of control for weight, scale for food preference and eating behavior. And we also used Eysenck Personality Questionnaire of Korean standardized edition for assessment of personality characteristics, Beck depression inventory, and the scale of hypochondriasis. The results were as follows: 1) Body mass index and the amount of cigarrette smoking and alcohol drinking showed significant differences by sex but not by need for weight control. 2) Eating habit of female athletes was the worst in all athletes. The score of eating attitude test of female athletes was higher than that of male athletes but there was no significant difference by need for weight control. Food preference and eating related behavior was also different by sex. 3) There were no significant differences in all subscales of Eysenck Personality Questionnaire, Beck depression inventory, and the scale of hypochondriasis between two groups which were divided by need for weight control. Neuroticism score was higher in female atheletes and psychoticism score was the highest in weight control male atheletes. 4) There was no significant difference in number of population with abnormal EAT score(to-tal score$\geq$26) between two groups which were divided by need for weight control. 5) The score of eating attitude test had positive correlation with the score of psychoticism and the tendency of depression in weight control male athletes but not in non-weight control male athletes. In non-weight control male athletes, the score of eating attitude test had positive correlation with the score of lie scale. so its correlation is different from those of weight control male athletes. But in female athletes, the score of eating attitude test had significant positive correlation with the score of psychoticism in both groups. In conclusion, these results suggest that the differences of eating traits in athletes are depend upon the sex difference, not upon the need for weight control. and that the role of weight control in eating disorder or abnormal eating attitude differs according to sex.

This study was conducted to investigate the degree of nurses' knowledge, attitudes, and compliance with hospital infection standard precautions. The study subjects were nurses in a university hospital in Daegu, South Korea, and a self-administered survey was carried out using a standardized questionnaire from 1st to 15th August, 2012. A total of 187 questionnaires were used for analysis. Those who were injured by a syringe needle for the last year accounted for 29.96%, and those exposed to patients' blood or body fluid on their damaged skin/mucous membranes accounted for 26.2%. There were statistically significant differences in attitude and compliance according to safety environment for hospital infection standard precautions. The knowledge score of the subjects about standard precautions was $15.30{\pm}1.51$ on a 19 point scale and had significant difference according to the subjects' education level. The attitude score was $2.86{\pm}0.49$ on a 4 point scale and had significant difference depending on how experienced they were on the career. The compliance score was $3.41{\pm}0.38$ on a 4 point scale and had significant difference depending on their age and their experience on the career. In conclusion, it can be said that systematic and continuous practical training is required to improve compliance with standard precautions. Particularly, it is needed to provide less experienced nurses with educational opportunities along with their supervisors' ongoing attention and position personnel appropriately.

This study was designed to investigate the elderly people's attitude toward death for the purpose of identifying the issues needed in the planning of health management and care activities for the aged. The total number of subjects in this study was 354 elderly people who were accommodated in house for elderly people (185) and school for elderly people (169). The scale for the attitude toward death of aged persons as an instrument of this study was mainly constructed with reference to Schneidman's attitude questioners toward death modified of adjust the Korean cultural characteristics and attitudes concerning death. Theresultsofthisstudywereasfollows: - 1. Out of total 45.8% of the respondents consider that death is a natural phenomena and ending of life. The responses on the meaning of death appeared differently : non-religions (48.1%) and oriental religions (50.3%) consider death as a natural phenomena however western religions (47.4%) consider that death is God's call. This difference was statistically significant. (x$^2$= 56.6419. df = 10. p<0.01). Respondents with a spouses (52.4%) think death is a natural phenomena opposed to respondent without spouses (33.3%). This was statistically significant. (x$^2$= 14.7134. df= 5 p<0.05). 2. Respondents in the house for aged persons (51.9%) replied. They do not wanted death because it meant a separation from their family as compared to those from school for aged persons (26.0%). 57.9% responded that they want to be told when death is confronted. 3. 51.2% of the respondents replied that the main factor to influence their attitude toward concept of death was the dying of their friends & relatives. 79.9% of respondents expressed that wished to die. The main reason for dying was economic shortage (28.3%). 4. 70.1% of the respondents want their body to be hurried while only 1.1% of the respondents want to donate their body to a medical research. 5. Over two thirds of the respondents replied that they do not believe in a life in heaven or that they will be rebirth. 6. The questioners of this study stimulated 56.8% of the respondents to feel that they should spend the leu of their life more effectively and 15.5% of the respondents felt it gave them the opportunity to think about their death seriously.

This study was designed and undertaken to analyse the factors associated with sexual satisfaction in diabetic patients. The data were collected from September to November, 1997. The subjects in this study were 77 diabetic patients who visited to check their blood glucose level to the outpatient department of internal medicine in one of hospitals located in Taejon city, The questionnaires developed by Derogatis L. R. were used. Data were analysed using percentages, means, 1-test, ANOVA and Peason-correlation coefficients, done with the SAS program. The results of this study were as follows ; 1. The mean score of sexual satisfaction in diabetic patients was higher than the mid level as 3.14 points in the 5 points scale and male patients' score was a little higher than female's. 2. The mean score of factors associated with sexual life was 3.54 points in spouses' support, 3.44 points in sexual attitude and 2.60 points in body image in the 5 points scale, and 2.76 points in the sexual act in the 6 points scale. The score of above all factors were higher in male patients than female patients. 3. The significant factors associated with sexual satisfaction were spouses' support, body image and sexual act. That is, the higher spouses' support, the more positive body image and the more frequent sexual act, the higher patients' sexual satisfaction. 4. In the relationships between the sexual satisfaction and the general characteristics of the diabetic patients, only religion and the period of disease were statistically significant differents, but the relationships between the sexual satisfaction and the period of disease showed a significant inverse correlation. This results showed that the degree of sexual satisfaction in diabetic patients was relatively high. The major factors associated with sexual satisfaction were spouses' support, body image and sexual act, religion and the period of disease. So, the above factors have to be considered during the nursing intervention on diabetic patients' sexual life.

Objects : This study was attempted to evaluate the body image and the self concept in high risk adolescents for eating disorders. Methods 589 middle school students were investigated with EAT(Eating Attitude Test) and BITE(Bulimic Investigatory Test Edinburgh) and Schematic Figures(Child/Adolescent Version) and Piers-Harris Self-Concept Scale. According to the score of EAT and BITE, three high risk groups(high EAT group, high BITE group, high EAT & BITE group) were identified. Three groups were examined in terms of sex, weight, self concept and body image. Each group was EAT group, BITE group, EAT & BITE group Results: The results of the study were as follows : 1) EAT & BITE group showed greatest body image distortion. 2) BITE group and EAT & BITE group showed lower score in self concept scale. 3) The majority of EAT group were boys, BITE group and EAT & BITE group were mostly girls. 4) All three high risk groups, especially Bin group, revealed overweight compared with normal control group. Conclusions : High BITE group and high EAT & BITE group could be considered as significantly high risk groups for eating disorders, showing overweight, severe body image distortion, and poor self concept. EAT score alone seemed not to discriminate high risk adolescents for eating disorders.

This paper presents a new attitude stabilization and control of an unmanned helicopter based on neural network compensation. A systematic derivation on the dynamics of an unmanned small-scale helicopter is performed. Combined rotor-fuselage-tail dynamics is derived in body-fixed reference frame with its origin at the C.G. of the helicopter. And the resulting nonlinear equation of motion consists of 6-DOF air vehicle dynamics as well as the rotor flapping and engine torque equations. A simulation model was modified using the existing simulator for an unmanned helicopter dynamic model, which reflects the unmanned test helicopter(CNUHELI). The dynamic response of the refined model was compared with the flight test data. It can be shown that a good coincidence was accomplished between the real unmanned helicopter system and the mathematical model. This dynamic model was linearized for classical controller design using small perturbation method. A Neuro-PD control system was designed for both longitudinal and lateral flight modes, and the results were compared with the PD-only control response. Simulation results show that the proposed Neuro-PD control system demonstrates better performance.
