Frozen orbit is an attractive option for orbital design owing to its characteristics (its argument of pericenter and eccentricity are kept constant on an average). Solar sails are attractive solutions for massive and expensive missions. However, the solar radiation pressure effect represents an additional force on the solar sail that may greatly affect its orbital behavior in the long run. Thus, this force must be included as a perturbation force in the dynamical model for more accuracy. This study shows the calculations of initial conditions for a lunar solar sail frozen orbit. The disturbing function of the problem was developed to include the lunar gravitational field that is characterized by uneven mass distribution, third body perturbation, and the effect of solar radiation. An averaging technique was used to reduce the dynamical problem to a long period system. Lagrange planetary equations were utilized to formulate the rate of change of the argument of pericenter and eccentricity. Using the reduced system, frozen orbits for the Moon sail orbiter were constructed. The resulting frozen orbits are shown by two 3Dsurface (semi-major, eccentricity, inclination) figures. To simplify the analysis, we showed inclination-eccentricity contours for different values of semi-major axis, argument of pericenter, and values of sail lightness number.

The purpose of this study was to investigate the effect of information of appearance, peer preference, and personality traits on children's attraction to unacquainted same sex peers, and to determine the relative importance of the three types of information for the selection of a friend. The subjects of this study were 160 (80 boys and 80 girls) second grade children in Seoul. A Preference Questionnaire was administered in Session I to determine the likes of each subjects. The modified Preference Questionnaire (Reaves, 1981) was used. The subjects were then randomly assigned to one of eight experimental conditions. In Session II, subjects were shown pictures of attractive and unacttractive children, described as having a positive or negative character, with preference similar Of dissimilar to their own. Then they were administered the Interpersonal Attraction Scale (Reaves, 1981). The data were analyzed by three-way ANOVA, $Scheff\acute{e}$ test, and $X^2$. The results of this study were as a follows: The physically attractive stimulus child was preferred to the physically unattractive stimulus child. The stimulus child with preferences similar to the subjects' was preferred to the stimulus with dissimilar preferences. The stimulus with positive personality traits was preferred to the stimulus ehild with a negative personality. A difference in order of importance among the variables with regard to their influence on attraction ratings was found. Personality had stronger influence on attraction ratings than appearance or preference.

Exposure and Concealment have been continued as important way to express fashion and theme as well, especially in women fashion. Exposure can make themselves attractive, and concealment emphasizes this way of being attractive by exposure. Besides the temptable effect of exposure, the ideology which put women next men in society has made a prominence on the fact exposure is significant theme in women fashion. It means that women's image of 'Being seen as Object' (this can be explained by relation passive between active) in society has driven female emphasize in using and focusing on exposure to be attractive. Also the other important thing in women fashion has been considered is concealment. The fact that society has demand women more chaste duty in detail may have meaningful thing in the condition that instigates women take off being attractive to the subject, considering ideology, men. Therefore attractive femininity has to be suggested by virtue and temptation, it is common sense that looking just shallow or too strict are far from criteria of ideal beauty. Namely, the concept for exposure coexists with concealment not only constructively but also naturally in fashion. Technique that can be accentuate for effective exposure differently from method to show unilaterally is needed, and this technique can promote new fashion. And according to the theory of Freud, women means' Absence (lacking penis)', this female's Lack Image induces male castration complex therefore 'Fetishistic Look' which transfers something phallic into specific things or parts of body is adopted, sort of object cathexis. This is revealed as some parts of women body are diverted into object for sexual love, symbolic equivalent. For example, women's parts like legs or breast are remarked as erotogenic zone and as time goes, when no more the zone are felt sexual by exposure, other somewhere felt mysterious (felt something sexual) used to be stressed by exposing. As it were, it can be possible that exposing part on women body (sexual part) moved as time passed because of what previously stated. Especially, the concept of exposure and concealment in women fashion should explain not only from a point of view of style for the beautifulness but also from wearer's immanent intention, further more relationship with ideology. About the present situation becoming bolder in women fashion, it is said that women express confidence as the position of women is elevated higher socially, the more women get freedom. But if we consider this psychoanalysis opinion mentioned ahead, the possibility can not be excluded that the exposure can get emphasizing according as the need of feminine modesty gets decreasing from ideal femininity society, men want. This study about exposure and concealment was made progressed through the theory of Freud who originated psychoanalysis, presented many theories. But nowadays contradictions are being brought up against Freud's theory including conventional philosophy like male chauvinism and adjust studies get suggested. Hereupon, there may be limitation in making no allowance of contradiction and following his theory.

The purpose of this study was to identify images of saleswomen by uniform and body type and to determine if the images have an effect on customer satisfaction and revisiting intention. This study was conducted between February 10th and February 23rd 2015, using a questionnaire to collect data from 608 adults from Seoul, Deajeon, and Chungnam Province. A $2{\times}2$ (body $type{\times}clothes$) factorial experimental design was used. Frequency, factor, and reliability analysis, analysis of variance, one-way ANOVA, Tukey test, and multiple regression analysis methods were used to analyze data. The study results were as follows: First, images of saleswomen with different uniform and body types were classified based on the following three factors: professionalism, kindness and attractiveness. Second, the saleswomen's uniforms had significant impact on perceived attractiveness, with women who wore skirt suits being identified as more attractive than women with pant suits. The saleswomen's body types had significant effect on professionalism, kindness and attractiveness. Women with average body types were perceived positively in terms of professionalism and attractiveness, whilst women with large body types were perceived positively in terms of kindness. Third, the combination of uniform and body type had a significant effect on perceived professionalism. Women with average body types wearing pant suits were perceived to have high degree of professionalism and women with large body types wearing skirt suits were evaluated to have high professionalism. Fourth, the images described as attractive and kind for both uniform and body type had a positive influences on customer satisfaction and revisiting intention.

The purposes of the study were 1) to evaluate the visual image of colored Korean traditional dress for woman 2) to analyze the colors and, color combinations effect on the image perception using gestalt theory. The research method was a quasi-experimental with a between subjects design. The experimental materials developed for the study were a set of stimuli and a response scale. The stimuli was consisted of 17 drawings of females wearing Korean tradinational dress, by using CAD simulation. A response scale consisted of semantic differential scales. The subjects were 1138 undergraduate students of Taejon city, Chungnam province and Chungbuk province. Their responses to the semantic differential scales were analyzed using factor analysis, one-way ANOVA, Duncan's multiple range test, 1-test. Results were as follows; 1) The image of the stimulus was consisted of the 4 different dimensions.(sociability, evaluation, visibility, attractiveness) 2) Clothing colors had significant effects on image perception of the evaluation dimension, visibility dimension and attractiveness dimension in the mono-color set. The blue showed the most positive image on the evaluation dimension, and the yellow and the gray showed negative image on the same dimension. The yellow showed the most salient image and the gray showed the least salient image on the visibility dimension. The red showed the most attractive image and the green showed the least attractive image on the attractiveness dimension. 3) In hi-color set stimulus, the perceived image was influenced by color combinations. The yellow blouse-the red skirt set showed the most sociable image on the sociability dimension. The blue blouse-the green skirt set showed the most positive image on the evaluation dimension. The yellow blouse-the red skirt set showed the most salient image and the blue blouse-the green skirt set showed the least salient image on the visibility dimension. And the red blouse-the yellow skirt set showed the most attractive image on the attractiveness dimension. On conclusion the visual image of Korean traditional dress wearer was affected by dress colors and color combinations.

The purpose of this study is to examine how the characteristics of virtual influencer, which are rapidly emerging in recent years, affect consumers. To this end, the change in information accecptance intention was examined using the perceived attractiveness and social distance of consumers toward virtual influencers as independent variables. I found the more attractive consumers feel about virtual influencer and the closer they perceive social distance, the higher the intention to accept information. However, when virtual influencer was perceived as attractive, there was no difference in information acceptance intention according to social distance. On the other side, even if the virtual influencer was perceived as less attractive, the information acceptance intention was higher when the social distance was perceived as close than when it was not. Based on these results, I provided implications for the marketing strategy of virtual influencers.

A circular tube undergoes bucking behavior when it is subjected to axial loading. An upper bound analysis can be an attractive approach to predict the buckling load and energy absorption efficiently. The upper bound analysis obtains the load or energy absorption by means of assumption of the kinematically admissible velocity fields. In order to obtain an accurate solution, kinematically admissible velocity fields should be defined by considering many factors such as geometrical parameters, dynamic effect, etc. In this study, experiments and finite element analyses are carried out for circular tubes with various dimensions and loading conditions. As a result, the kinematically admissible velocity field is newly proposed in order to consider various dimensions and the strain rate effect of material. The upper bound analysis with the suggested velocity field accurately estimates the mean load and energy absorption obtained from results of experiment and finite element analysis.

The purpose of this study was to find out the effect of color, tone, perceiver's gender on image perception of natural dyeing of cotton and mosi. The experimental materials developed for this study were a set of stimuli and response scale(The 7-point semantic). The stimuli was 20 fabrics manipulated with two kinds of fabrics(cotton, mosi), five colors(red, yellow, blue, green, purple) and two tone variations. The subjects were 412 adults in Daejeon and Kongju. The results were as follows: The perceived image of the stimulus material consisted of 4 dimensions (attractive, conspicuous, hand, weight) colors, tons, materials as well as perceiver's gender affected on some selected image dimensions color affected on the four image dimensions, tone affected on the conspicuous, hand and weight images, materials affected on the attractive and hand image and perceiver's gender affected on the weight image. Interaction effects existed among colors, tons and materials on the conspicuous image. In conclusion the results support gestalt theory in which the sum of the parts is bigger than the whole and design strategies for the Mosi fabrics should be developed on the basis of persuited design image as well as target consumers.

Controlled source audio-frequency magnetotelluric (CSAMT) has the great advantage of efficient mapping resistivity distribution and relatively deep depth of investigation. Moreover, CSAMT may be regarded more attractive than audio-frequency magnetotelluric in the sense of the strong and controllable signal. However, it has the problem such as undershoot and/or near-field effect that is hard to be interpreted if the interpretation method of MT is directly applied. The problem arises from the existance of controlled source which makes CSAMT attractive. So the characteristics of CSAMT response should be thoroughly understood prior to interpretation stage. In this study, numerical modeling program for horizontally layered earth was developped for the interpretation of CSAMT field data. CSAMT field survey was run as a follow-up to resistivity dipole-dipole study over the same survey line at Bongmyung coal mine. The survey used a grounded dipole source 2 Km in length and located 7.5Km south in this study. A good agreement between field CSAMT data and calculated data was demonstrated even in geologically complex earth situations.
