  • The firing noise produced at artillery test range or military training ground is impulsive burst noise which energy is generated within tens of milliseconds and distributed an isolated burst of sound energy separated to one by one noise. The long range propagation of this noise is affected by a caliber of gun, amount of propellant, distance between source and receiver, ground and meteorological condition. In this paper, main influence parameters have been described based on experimental analysis of measured data. It is considered that this analysis result can be used as useful materials for study of effective firing noise management and development of propagation model.

  • Purpose - This study focuses on an empirical analysis of the factors affecting the behaviors of consumers who are extremely attached to branded products, and who commit themselves to renting them. Research design, data, methodology - The survey was conducted on college students enrolled in marketing classes. In total, 240 questionnaires were distributed. A total of 226 were returned. Questionnaires, excluding those that were void, were used for empirical analysis. We confirmed that the research model is sound by using a covariance structural analysis, and estimated its parameters. To estimate these parameters, a maximum likelihood method was used. Results - This study confirms that prominence and self-expressiveness positively affect brand attachment. Further, positive beliefs about, and the practicality of renting branded goods, influence attitudes toward their rental. In addition, commitment to renting branded goods is positively affected by attachment to the brand and attitude towards goods rental. Conclusions - Marketers should manage positive beliefs in and the practicability of renting branded goods, as well as the self-expressiveness and prominence of such products.

  • This study is to find out how much elementary school members have their consciousness against safety in their school. Simple questionnaire 1206 sheets have been distributed to the members and additional interview with teachers to take care of them. Statistically, frequency, and correlation analysis have been made and chi-test has also been made for data reliability. The results of these have been summarized as running on corridor with 53.4% in school safety, warming up exercise 45.2% in leisure safety, evacuation form classroom with 2.4% in fire safety, crossing around just in fromt or rear of vehicle with 61.2% in transportation safety. It is thought that safety training should be provided to more for man than for girl pupils and also, safety consciousness should be improved than all the other area.

  • The purpose of this study was to find out the effects of mother's parenting attitudes on children's clothing orientation and clothing purchase behaviors. The questionnaires for this study were distributed to 166 fifth and sixth graders of elementary schools and 166 their mothers in Seoul. The data were analyzed through chi-square test, factor analysis, cluster analysis, MANOVA, ANOVA, and LSD test. Responses were classified as 4 groups (Acceptance-Autonomy, Acceptance-Control, Rejection-Autonomy, and Rejection- Control groups) based on mother's parenting attitude. The four groups showed significant differences both in clothing orientation and clothing purchase behaviors. Especially, the Rejection-Control group, which is easily influenced by peer students, placed much emphasis on fashionability of clothing and showed strong complaining behaviors toward unsatisfactory clothing selected by their mothers. Study results suggest the importance of mother's parenting attitude on analysis of target market for children's wear.

  • The purpose of this study was to provide the guidance in more objective and proper clothing design reflecting today's consumers' modes in value consumption by identifying the meaning structure and relationship between fashion sensibility and emotion. The stimulus was 54 photos of contemporary costume which represented the Izard' DES. The questionnaire consisted of hi-polar 25 pairs adjective scale of fashion sensibility and the 18 noun scale of emotion was distributed to 970 male and female living in Pusan area. The data were analyzed by Factor analysis, Correlation analysis and Regression analysis using the statistical SPSS package. The major finding of this research were as follows.1. Fashion sensibilities consist of estheticism, maturity, character and feminity to represent 57.17% total varlarlce. 2. Emotions consist of negative emotion, distress afraid, arousal, shame and enjoyment to represent 70.84% total variance. 3. For the relation between fashion sensibility and emotion, they showed significant relationship in most of factors.

  • The aims of this study were to identify benefits sought for herbal cosmetics and its significance in influencing consumers' attitude and brand choice. A questionnaire was distributed to 900 women between 20 and 50 years old who had purchased herbal cosmetics from Nov. 6, 2006 to Dec. 15, 2006. SPSS 12.0 package was used for data analysis. Factor analysis, $X^2$-test, frequency, percentage, multiple regression analysis were utilized. The results were as follows: 1. The benefits that consumer was seeking from herbal cosmetics could be classified into 9 dimensions; special function, brand, nutritional reinforcement, economy, scarcity, feeling, fragrance, fashion and skin fitness. 2. All of the above benefits sought except economy and fashion had positive impact on consumers' attitude of herbal cosmetics. 3. There was a correlation between types of benefits sought by consumers and their brand selection.

  • This paper presents the solution scheme of using the continuous formulation of 1-D linear member for the dynamic analysis of structures consisting of axially loaded members. The context describes specific applications of such scheme to the verification of experimental data obtained from field test of bridges carried out by a microwave interferometer system and velocimeters. Attention is focused on analysis outlines that may be applicable to in-situ assessment for cable-stayed bridges. The derivation of the dynamic stiffness matrix of a prismatic member with distributed properties is briefly reviewed. A back calculation formula using frequencies of two arbitrary modes of vibration is next proposed to compute the tension force in cables. Derivation of the proposed formula is based on the formulation of an axially loaded flexural member. The applications of the formulation and the proposed formula are illustrated with a series of realistic examples.

  • To predict efficiency of Interior Permanent Magnet Synchronous Motors(IPMSM) and to cope with the demagnetization risk of permanent magnets used in the IPMSM, accurate iron analysis of the IPMSM is very important at the motor design stage. In the analysis, we developed a new iron loss model of electrical machines for high-speed operation. The calculated iron loss was compared with the experimental data. It was clarified that the proposed method can estimate iron loss effectively at high-speed operation.
