The purpose of this study was to investigate the effect of use motivation type for mobile phones and the degree of loss perception related to mobile phone consumption consciousness in adolescents. The subjects of this study were 503 students in middle and high school in Daegu. A questionnaire was used for the survey. Factor analysis, cluster analysis, and MANOVA were employed for the data analysis and the $Scheff\acute{e}$ test was used for post-hoc analysis. The results are as follows: First, there are significant differences in mobile phone consumption consciousness in all sub-dimension areas according to use motivation type for mobile phone. Second, adolescents with high economic loss perception for mobile phones show high consumption consciousness in sub-dimension area, and adolescents with high academic loss perception show high relation-oriented consumption consciousness. Adolescents with high physical loss perception show high health-oriented, relation-oriented, and function-oriented consumption consciousness. Adolescents with high psychological loss perception, on the other hand, show high relation-oriented consumption consciousness. Third, there are significant differences in mobile phone consumption consciousness according to use motivation type for mobile phones and the degree of overall loss perception. However, there are no significant differences in the mobile phone consumption consciousness according to use motivation type for mobile phones and the degree of overall loss perception.

Background: Body image is associated with the perception of people on themselves. Influencing factors are generated internally and/or externally. The most common issue pertaining to body image is body weight and weight loss. This study aimed to determine the association between body weight perception and weight loss practices among college students. Methods: A cross-sectional study was conducted involving 297 college students from private nursing colleges in the state of Kelantan, Malaysia. A self-administered questionnaire was used to assess sociodemographic characteristics, body weight perception, and weight loss methods. Weight and height were measured, and body mass index (BMI) was calculated based on weight and height measurement. The World Health Organization BMI cutoffs were applied in the study. Results: More than half (54.2%) of college students perceived their weight correctly as per actual measured BMI. A total of 51.5% of participants had tried various methods to reduce their weight. Body weight perception is associated with weight loss practices (odds ratio, 0.31; 95% confidence interval, 0.19-0.50; P<0.001) adjusted for sex, marital status, and status of having obese family members. Those who had correct body weight perception were less likely to engage in weight loss practice. Food intake restriction (42.4%) is the most popular weight reduction method among students in nursing colleges. Over a quarter of the participants chose physical exercise (25.3%) to reduce their weight, and a small number engaged in unhealthy weight loss practices. Conclusion: Body weight perception is an important factor that influences the practice to reduce weight especially among young adult group and college students.

Background and Objectives: Non-linear frequency compression (NLFC) technology compresses and shifts higher frequencies into a lower frequency area that has better residual hearing. Because consonants are uttered in the high-frequency area, NLFC could provide better speech understanding. The aim of this study was to investigate the clinical effectiveness of NLFC technology on the perception of speech and music in patients with high-frequency hearing loss. Subjects and Methods: Twelve participants with high-frequency hearing loss were tested in a counter-balanced order, and had two weeks of daily experience with NLFC set on/off prior to testing. Performance was repeatedly evaluated with consonant tests in quiet and noise environments, speech perception in noise, music perception and acceptableness of sound quality rating tasks. Additionally, two questionnaires (the Abbreviated Profile of Hearing Aid Benefit and the Korean version of the International Outcome Inventory-Hearing Aids) were administered. Results: Consonant and speech perception improved with hearing aids (NLFC on/off conditions), but there was no significant difference between NLFC on and off states. Music perception performances revealed no notable difference among unaided and NLFC on and off states. The benefits and satisfaction ratings between NLFC on and off conditions were also not significantly different, based on questionnaires, however great individual variability preferences were noted. Conclusions: Speech perception as well as music perception both in quiet and noise environments was similar between NLFC on and off states, indicating that real world benefits from NLFC technology may be limited in Korean adult hearing aid users.

Price discount is one of the commonly used promotion strategies to increase sales and revenue. If a discount is perceived before the purchase (i.e., pre-purchase discount), consumers are likely to perceive it as a potential gain. If it is noticed after making a regular-priced purchase (i.e., post-purchase discount), consumers may develop negative emotions and attitudes. Based on the rising transparency and omnipresence of price and discount information through web and mobile platforms, we attempt to tackle an understudied topic on the negative effect of post-purchase price discount. Specifically, post-purchase discount information may increase consumers' perception of monetary loss, which may affect consumers' decision to return the product, potentially increasing the operating costs borne by retailers. Based on a close scrutinization of the current market environment and previous academic literature, we suggest a novel conceptual framework to understand consumers' perception, attitude, and behavior (perception of loss, willingness to return) upon perceiving various formats of discount promotion (absolute value vs. percentage discount) posterior to the purchase of a product. We also look at the effect of price level (low-priced vs. high-priced). For marketing practitioners, we intend to suggest optimal promotion formats that can alleviate consumers' negative perceptions and prevent additional operation costs.

This study was designed to examine the phoneme recognition errors of hearing-impaired (HI) listeners on a consonant-by-consonant basis, to show (1) how each HI ear perceives individual consonants differently and (2) how standard clinical measurements (i.e., using a tone and word) fail to predict these differences. Sixteen English consonant-vowel (CV) syllables of six signal-to-noise ratios in speech-weighted noise were presented at the most comfortable level for ears with mild-to-moderate sensorineural hearing loss. The findings were as follows: (1) individual HI listeners with a symmetrical pure-tone threshold showed different consonant-loss profiles (CLPs) (i.e., over a set of the 16 English consonants, the likelihood of misperceiving each consonant) in right and left ears. (2) A similar result was found across subjects. Paired ears of different HI individuals with identical pure-tone threshold presented different CLPs in one ear to the other. (3) Paired HI ears having the same averaged consonant score demonstrated completely different CLPs. We conclude that the standard clinical measurements are limited in their ability to predict the extent to which speech perception is degraded in HI ears, and thus they are a necessary, but not a sufficient measurement for HI speech perception. This suggests that the CV measurement would be a useful clinical tool.

본 연구는 소비자가 판촉을 인식할 때 판촉이 제시하는 혜택을 소비자가 지불해야 하는 현금손실을 감소시켜주는 것으로 보는지 혹은 정상적인 거래이후에 추가적으로 받게 되는 이득으로 인식하는지에 따라서 판매촉진에 대한 가치평가가 달라지게 된다는 것을 검증하기 위한 것이다. 구체적으로 판촉도구의 특성차원 세 가지, 혜택의 실현시점이 즉각적일수록, 판촉물의 현가계산의 용이할수록, 판촉물과 본래제품이 유사시점에 구매할수록 소비자가 지불해야 하는 현금손실을 줄여주는 것으로 인식할 것이며, 이와 같이 감소된 손실로 인식되는 판촉이 추가된 이득으로 인식되는 판촉보다 판촉의 가치평가가 더욱 클 것으로 가정하였다. 대학생을 대상으로 집단간/내 설계를 통하여 자료를 얻고 ANOVA와 구조방정식 모형으로 가설을 검증하였다. 결과적으로 현가계산과 유사시점구매는 검증되었으나 혜택실현시점가설은 통계적으로 유의하지 않았다. 감소된 손실은 추가된 이득보다 판촉가치평가에 더 효과적이었고, 나아가서 구매의도를 더 높혀주었다.

The purposes of study were to investigate the prenatal psychological adaptation and the perception of birth experience, and to identify the relationship between them. The subjects consisted of 162 women who visited the obstetrical outpatient clinic for prenatal examinations and who delivered the in babies at SNUH during the period from June 20 to August 10, 1990. The tools used for measurement were Lederman's Prenatal Self Evaluation Questionnaire and Marut & Mercer's scale of the Perception of Birth. The results are summarized as follows : 1. The orders and item means of psychosocial adaptation in pregnancy were the Acceptance of pregnancy(1.58). Identification of motherhood role(1.63). Relationship with husband(1.65) and Relationship with mother(1.67). The preparation for labor, concern for wellbeing of self and baby, and fear of pain, helplessness and loss of control were found to be less adaptive. 2. The level of the perception of the birth experience was mid-range(item mean : 3.22). The score of the perception of birth experience for primiparas was higher than for multiparas. However there was not a significant difference the groups. There were significant differences in the perception of the birth experience between certain general characteristics, namely, sex of the baby(p＜0.05), type of delivery(p＜0.005), and type of anesthesia(p＜0.005). 3. There were significant differences in the perception of the birth experience between the groups below the mean and above the mean of concerti for wellbeing of self and baby, Fear of pain, Helplessness and loss of control, Relationship with husband and Identification of motherhood role (p＜0.05). The perception of the birth experience was predicted by Fear of pain, Helplessness and loss of control (11%), Type of Delivery(6%), Concern for wellbeing of self and baby(3%), Preparation for labor(1%), sex of baby(1%), Relationship with mother(1%), Parity(1%) and Identification of motherhood role(1%). The Childbirth education should be revised to improve the psychosocial adaptation in pregnancy.

This paper examined the risks perceived by consumers in apparel buying situation by 1) measuring the contents and perception level of risk, 2) categorizing each risk into meaningful factors (risk types), 3) analyzing the relationships between risk types and consumers' demo-graphic variables. 224 respondents deliberately selected to include each level of S demographic variables were contacted with 37-item question3.ire. Factor analysis showed that 32-item perceived risk could be categorized into 6 risk types: psychological. social, economic, time/convenience loss, fashionability loss, performance risk. Psychological risk were perceived highest in terms of perception level while social and performance risk showed relatively low perception level. 4 of 5 demographic variables including sex, education level, income, occupa-tion showed partial relationship with each risk type after ANOVA and Duncan test. Sex had the greatest influence on risk perception level and each age level (20's, 30's, 40's) showed different risk structure.
