Acoustic behavior in gas turbine combustor with acoustic resonator is investigated numerically by adopting linear acoustic analysis. Helmholtz-type resonator is employed as acoustic resonator to suppress acoustic instability passively. The tuning frequency of acoustic resonator is adjusted by varying its length. Through harmonic analysis, acoustic-pressure responses of chamber to acoustic excitation are obtained and the resonant acoustic modes are identified. Acoustic damping effect of acoustic resonator is quantified by damping factor. As the tuning frequency of acoustic resonator approaches the target frequency of the resonant mode to be suppressed, mode split from the original resonant mode to lower and upper modes appears and thereby complex patterns of acoustic responses show up. Considering mode split and damping effect as a function of tuning frequency, it is desirable to make acoustic resonator tuned to broad-band frequencies near the maximum frequency of those of the possible upper modes.

This study is a review of the clothing behavior of kidult group that is a new minority group in 21st century. Kidult is the compound word of kid and adult and refers the persons who have become adults but with the inclination to focus on childlike culture and consumption. As the background of the appearance of the kidult group these days, the prevalence of throwback fashions, high valuation of appearance, the phenomenon to prefer light things caused by economic depression, the individualism that does not care about others and the ageless phenomenon that the consumptions are mind age oriented, may be pointed out. The most prominent cloth behavioral characters of the kidult group are that they enjoy bounding color combinations such as candy color and. that cute t-shirts, crop pants and volume skirts of girlish look are easily found. Also, they enjoy toy-like ornaments and illustrated clothes or accessories and the school uniform fashion implying nostalgia for girl-hood and lovely make-up indicate the kidult inclination.

As the life style of modern people is gradually being more scientific, up-to-date, and specialized, food habit and food cut lure are a measure of cultural level of a country. Studies on consumer behavioral model show that food habit is closely related to consumer preference, changing life pattern and increasing family income. The purpose of this study was, accordingly, to define the impact of menu characteristics on customer menu selection. For that purpose, some at tempts were made: First, discuss the theories on family restaurant and customer purchasing behavior as a standard of analysis. Second, find out if there are any differences in customer menu- selection factors in family restaurant Third, make an empirical analysis of menu-selection factors in family restaurant to suggest in which direction it should move forward Fourth, analyze the relationship of demographic characteristics to menu-select ion factors.

The purpose of this study was to investigate the differences of lifestyle and clothing behavior of high school girls according to their residential area. The focus group interview was executed with 29 high school students and picture analysis was carried with 400 pictures of their outfits on weekends. The results show that they borrow their clothing one another taking turns, and there has lesibean dress code in common regardless of residential area. Students residing in Seoul wear brand products, and buy at department store, discount store and the stores in Myongdong or Sinchon, while students residing in Inchon wear Bose products, and buy at the stores in subway. Most of adolescents wear easy casual, and those of Inchon sometimes wear formal with high heel and young character casual, and often wear make up and get hair permanant/dyeing.

This study investigated the relationships among cognitive age, sociocultural attitudes towards appearance, and appearance management behaviors. This study gave a questionnaire survey to adults between the ages of 17 and 76 who lived in the Daegu and Gyeongbuk regions of South Korea. Data collected from the 296 respondents were analyzed using descriptive statistics, correlation analyses, and ANOVA. The sociocultural attitudes towards appearance (awareness and internalization) were significantly correlated with appearance management behaviors (weight training, skin care, hair care, make-up, and clothing selection). The cognitive age was significantly correlated with the sociocultural attitudes towards appearance and appearance management behaviors such as weight training and clothing selection.

This paper studies the response of seismic behavior of reinforced concrete exterior beam-column joints under reversal loading with different anchorages and joint core details. The joint core was detailed without much confinement (group-I) and/or with proposed X-cross bars in the core (group-II). The beam longitudinal reinforcement's anchorages were designed as per ACI 352 (headed bars), ACI 318 (conventional $90^{\circ}$ bent hooks) and IS 456 ($90^{\circ}$ bent hooks with extended tails). The nonlinear finite element analysis response of the beam-column joints was studied, along with initial and progressive cracks up to failure. The experimental and analytical results were compared and presented in this paper to make more scientific conclusions.

This study examines the effects of fashion and beauty consumption behavior on self-satisfaction. A questionnaire method was used for the study method and the subjects of the study were females in their 20s- 50s. A total of 580 sets of questionnaires were distributed and 554 sets were used for the final analysis; in addition, SPSS 12.0 statistics program was utilized for factor analysis, reliability analysis, correlation analysis, one-way ANOVA, Duncan test and multiple regression analysis. The results of this study were: First, the factors of fashion consumption behavior are composed of physical supplementation, social symbolism, appearance styling, sexuality and conformity and those of beauty involvement consisted of hair styling, skin management, make-up and body shaping. Self-satisfaction was divided into living satisfaction, appearance satisfaction, economic satisfaction and interpersonal relations satisfaction. Second, (because of the examination of the effects of fashion consumption behavior on self-satisfaction) fashion physical supplementation and appearance styling of fashion consumption behavior influenced living satisfaction and interpersonal relations satisfaction for females in their 20s. However, fashion consumption behavior did not influence satisfaction for those in their 30s. It was shown that the social conformity factor of fashion consumption behavior influenced appearance satisfaction of self- satisfaction for those in their 40s and the conformity factor of fashion consumption behavior gave a negative influence on life satisfaction and economic satisfaction of self-satisfaction for those in their 50s. It was found (for beauty consumption behavior) that the body-shaping factor influenced economic satisfaction and interpersonal relations satisfaction of self-satisfaction for all age levels.

Chinese economic growth and Chinese adoption of foreign cultures have changed varied phenomena, consumption patterns and consumer life-styles, in particular. In order to understand behavior of Chinese consumers, it is critical to explore their lifestyles and its effects on their purchase behavior. For attaining this goal, our research classifies Chinese consumer lifestyles related to cosmetics, into four types: brand oriented, price sensitive, rational consumption, and impulse buying. The research further analyzes the effects of consumer lifestyles on perceived value, satisfaction, and purchase intention in each case of skin care cosmetics and make-up cosmetics. Significant difference are found in perceived value, satisfaction, and purchase intention of skin care cosmetics exists between brand-oriented type and rational consumption type. This is also the case between rational consumption type and impulse buying type. Purchase intention is only found to be different between rational consumption type and price sensitive type. In case of make-up cosmetics, significant differences in perceived value, satisfaction, and purchase intention in the pairs of brand-oriented type and rational consumption type, rational consumption type and impulse buying type, and rational consumption type and price sensitive type. This implies rational consumption type should be more appropriate target consumers in the Chinese cosmetics market.
