Middle age is the time of the most important meaning in life and also the time of physical and mental change, which offers new social activities for self-development. Middle-aged women form the major consumer class in current clothing industry, but few have been performed on this so far. The researcher studied in many aspect on the clothes which middle-aged women need to wear during this period of change. Thus this study is executed to examine what benefits middle-aged women pursue in clothing attitudes and the relationship among clothing pursuit benefit and their somatotype compensation and image orientation. The research performed the theoretical study and practical study simultaneously. The subjects are 238 middle-aged women between 35 and 49 years old in September, 2004. The results of this study are as follows: 1. The attitude of women's clothing patterns in relation with image consist of two factor structures. One is the body image and the other is the appearance image. 2. As a result of researching the attitude for choosing clothes of each body group by Rohrer index, the women with gross body group take a top priority for the lower-body compensation, while the women with slim body group take a top priority for volume compensation. 3. As a result of researching the cognitive somatotype group's attitude for choosing clothes, gross body group takes a top priority for lower-body compensation and upper-body compensation. 4. As a result of researching the relationship between real somatotype and cognitive somatotype by Rohrer index, middle-aged women think of themselves as being fatter than present state. And choosing the clothes, the body misunderstanding group of women usually show that they consider more compensation than the normally body understanding group. 5. The evaluation on real somatotype, cognitive somatotype, ideal somatotype influences on the body cathexis.

For spacecraft attitude control, reaction wheel (RW) steering laws with more than three wheels for three-axis attitude control can be derived by using a control allocation (CA) approach.1-2 The CA technique deals with a problem of distributing a given control demand to available sets of actuators.3-4 There are many references for CA with applications to aerospace systems. For spacecraft, the control torque command for three body-fixed reference frames can be constructed by a combination of multiple wheels, usually four-wheel pyramid sets. Multi-wheel configurations can be exploited to satisfy a body-axis control torque requirement while satisfying objectives such as minimum control energy.1-2 In general, the reaction wheel steering laws determine required torque command for each wheel in the form of matrix pseudo-inverse. In general, the attitude control command is generated in the form of a feedback control. The spacecraft body angular rate measured by gyros is used to estimate angular displacement also.⁵ Combination of the body angular rate and attitude parameters such as quaternion and MRPs(Modified Rodrigues Parameters) is typically used in synthesizing the control command which should be produced by RWs.¹ The attitude sensor signals are usually corrupted by noise; gyros tend to contain errors such as drift and random noise. The attitude determination system can estimate such errors, and provide best true signals for feedback control.⁶ Even if the attitude determination system, for instance, sophisticated algorithm such as the EKF(Extended Kalman Filter) algorithm⁶, can eliminate the errors efficiently, it is quite probable that the control command still contains noise sources. The noise and/or other high frequency components in the control command would cause the wheel speed to change in an undesirable manner. The closed-loop system, governed by the feedback control law, is also directly affected by the noise due to imperfect sensor characteristics. The noise components in the sensor signal should be mitigated so that the control command is isolated from the noise effect. This can be done by adding a filter to the sensor output or preventing rapid change in the control command. Dynamic control allocation(DCA), recently studied by Härkegård, is to distribute the control command in the sense of dynamics⁴: the allocation is made over a certain time interval, not a fixed time instant. The dynamic behavior of the control command is taken into account in the course of distributing the control command. Not only the control command requirement, but also variation of the control command over a sampling interval is included in the performance criterion to be optimized. The result is a control command in the form of a finite difference equation over the given time interval.⁴ It results in a filter dynamics by taking the previous control command into account for the synthesis of current control command. Stability of the proposed dynamic control allocation (CA) approach was proved to ensure the control command is bounded at the steady-state. In this study, we extended the results presented in Ref. 4 by adding a two-step dynamic CA term in deriving the control allocation law. Also, the strict equality constraint, between the virtual and actual control inputs, is relaxed in order to construct control command with a smooth profile. The proposed DCA technique is applied to a spacecraft attitude control problem. The sensor noise and/or irregular signals, which are existent in most of spacecraft attitude sensors, can be handled effectively by the proposed approach.

The purpose of this study is to examine the effect of media on plastic surgery experiment. Firstly this study try to find the relationship between exposure to media and other intervening factors(e.g., body image, self-esteem, fashion attitude). The data collected for this study was gathered through questionnaire survey with 443 female students in Seoul. The results are as follows: Using ANOVA, we found that those prefer the magazine over TV or Internet had positive body image, higher self-esteem, and positive fashion attitude(e.g., personality/self-expression, fashion leadership, sexual attraction). Using regression analysis, we found that the we found that the factors influence plastic surgery behavior are the exposure to magazine and the factors influence plastic surgery planning are the clothing attitude (especially fashion leading power, sexual attraction).

The purpose of this study is to classify the appearance concern into groups and analyze the differences of the attitude toward plastic surgery and clothing behavior by groups. Questionnaires are administered to 206 female adults in their 20's-50's living in Deagu and Kyungbook areas from $10^{th}$ July to $19^{th}$ July, 2013. Frequency, factor analysis, reliability analysis, correlation analysis, cluster analysis, ANOVA, Duncan-test and ${\chi}^2$-test were used for data analysis. The appearance concern is categorized as follows: appearance harmony focus and body focus. The attitude toward plastic surgery was found as risk tolerance, image improvement/surgery desire and keeping the secret of surgery. Clothing behaviors are found as individuality focus, other focus, convenience and luxury ostentation. The appearance concern shows a significant correlation with the sub-variable attitude toward plastic surgery and clothing behavior. One test in the groups is determined by demographic variables like occupancy and monthly income. Appearance concerns are classified into three groups as follows: appearance concern group, low appearance concern group and body concern group. The groups show a significant difference in the attitude toward plastic surgery and clothing behavior. This difference indicates that the 20's show a high body focus on their appearance concern, an attitude of image improvement/surgery desire toward plastic surgery and another individuality focus on clothing behavior while 50's care more about convenience in their clothing behavior.

In this paper, the performance of a new alternative form of three-axis attitude estimation algorithm for a rigid body is evaluated via simulation for the situation where the observed vectors are the estimated baselines of a GPS antenna array. This method is derived based on a simple iterative nonlinear least-squares with four elements of quaternion parameter. The representation of quaternion parameters for three-axis attitude of a rigid body is free from singularity problem. The performance of the proposed algorithm is compared with other eight existing methods, such as, Transformation Method (TM), Vector Observation Method (VOM), TRIAD algorithm, two versions of QUaternion ESTimator (QUEST), Singular Value Decomposition (SVD) method, Fast Optimal Attitude Matrix (FOAM), Slower Optimal Matrix Algorithm (SOMA).

The conventional closed-loop guidance commands are generated from a simplified point mass model for real time operations. In real situations, the generated guidance commands are applied to the original rigid body. This can cause attitude instability of the vehicle. In this paper, in order to solve the attitude instability problem in the guidance system sense, the influence of the guidance commands on a launch vehicle attitude is derived quantitatively. The checking method of the attitude stability conditions that uses Liapunov theorem is proposed, and the attitude stabilizing method is also proposed. The attitude stability is accomplished by subtracting the influence of the guidance commands that destabilize the vehicle attitude. The closed-loop guidance commands generated from the simplified point mass model may destabilize the vehicle attitude, which is verified through simulations. In this case, the vehicle attitude can be always stabilized with the proposed attitude stabilizing method without additive fuel consumption.

Purpose: This study was done to identify psychosocial factors that might be predictive of sexual desire, arousal, lubrication, orgasm, satisfaction, and pain in women with gynecologic cancer. Methods: Two hundred and twelve women with cervical, ovarian, or endometrial cancer completed questionnaires on the Female Sexual Function Index including sexual desire, arousal, lubrication, orgasm, satisfaction, and pain, and data on their psychosocial factors including body image, sexual attitude, sexual information, depression, and marital intimacy. Stepwise multivariable regression analysis was performed to explore psychosocial predictors of women’s sexual function domains. Results: Predictors were identified as sexual attitude, depression, sexual information, and body image for sexual desire; sexual information, depression, and sexual attitude for sexual arousal; sexual information, marital intimacy, and depression for lubrication; sexual information, marital intimacy, depression, and body image for orgasm; marital intimacy, sexual information, sexual attitude, and depression for satisfaction; sexual information, depression, and marital intimacy for pain. Conclusion: The results indicate that women’s sexual function needs to be approached to domains of female sexual function psychosocially as well as to general sexual function. These factors should be considered in future interventions to positively promote sexual function in women with gynecologic cancer.

Purpose: This study was conducted to define factors influencing health-related quality of life (HRQOL) in women undergraduates. Independent variables of physical activity, attitude to eating, satisfaction with body shape, stress and self-esteem were used to predict HRQOL. Method: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. Participants were 245 women undergraduates who were recruited from July to September 2012. Result: The mean for the physical component summary (PCS) of HRQOL was 73.89, and for the mental component summary (MCS) was 68.45. There were significant correlations between attitude to eating, satisfaction with body shape, stress, self-esteem and the two components of HRQOL. The groups with minimal or health enhancing activity were significantly higher in PCS and MCS than the inactivity group. Stepwise multiple regression analysis indicated that 35% of the variance in PCS was significantly accounted for by self-esteem, perceived stress, attitude to eating, and physical activity, and 45% of the variance in MCS was significantly accounted for by perceived stress, self-esteem, attitude to eating, and satisfaction with body shape. Conclusion: The results indicate that these factors influencing HRQOL should be considered when developing programs to improve HRQOL for women undergraduates.

The purpose of this study was to identify the factor structure of sociocultural attitude toward Appearance, pursuit of clothing benefits, ambivalent consumption of fashion product and the effects of sociocultural attitude toward appearance and pursuit of clothing benefits on ambivalent consumption of fashion product. Questionnaires were administered to 425 women living in Deagu Metropolitan City and Kyungbook province. The data collected were analyzed by using frequency, factor analysis, multiple regression, ANOVA, and Duncan-test. The findings are as follows. Sociocultural attitude toward appearance was composed of two factors such as internalization, and awareness. Pursuit of clothing benefits was composed of four factors such as individuality oriented, social oriented, fashion leadership oriented, and body oriented. Ambivalent consumption of fashion product was composed of three factors such as style/price ambivalence, place of purchase ambivalence, and brand ambivalence. The effects of sociocultural attitude toward Appearance and pursuit of clothing benefits on each of ambivalent consumption of fashion product variables like style/price ambivalence, place of purchase ambivalence, and brand ambivalence were explained by the factors such as internalization, and awareness, and individuality oriented, social oriented, fashion leadership oriented, and body oriented.
