The age of acquisition effect is the phenomenon in which the words acquired early in life are processed better than the words acquired later in life. Age of acquisition and word frequency are critical factors in lexical processing. In this study we examined the age of acquisition effects in Hangul word recognition. In Experiment 1, we examined the AoA effects in word naming and lexical decision tasks. The results showed that there was an interaction between task and age of acquisition. The AoA effects appeared only in the lexical decision task. In Experiment 2, we examined the relationship between age of acquisition and word frequency in the lexical decision task. The results showed that the two variables were significant. The early-acquired words were processed better than the words acquired later, and the words with high frequency were processed better than the words with low frequency. However, there was no interaction between the two variables. In Experiment 3, we examined how phonological changes in Hangul words influence the AoA effects. The results show that the AoA effects were similar whether phonological changes occur or not. Our results are discussed in terms of several theoretical hypotheses.

1. Today mass communication informs us of the unethical behaviors of business almost everyday and the social interest about them including individuals implicated in loss and gain grows larger. It is the real aspect that business manager and scholars do not cope with the situation. 2. Five business ethical scales as justice theory, relativism, egoism, utilitarianism, deontological theory and information ethics were applied to this thesis. 3. Hypothesis : There will he a difference in the response on five ethical scales and the recognition degree of information ethics with consumers. 4. The response on five ethical scales with the sex of consumers showed a significant difference but that with the age showed a little difference that with the academic career showed a significant difference in justice theory, relativism, utilitarianism and deontological theory 5. The recognition degree of information ethics with the age and academic career of consumers showed a significant difference and the hypothesis was accepted, but that with the sex showed a little difference.

The purpose of this study was to analyze the words of the songs in children's games in order to determine the traditional characteristics of their rhythm and subject matter and to investigate age and sex differences in recognition of the songs. 71 play songs were used for content analysis. After this, 840 subjects in 15 grades (preschool, first to 12th grades, and college students) were presented with the songs. Statistical analysis was done by one-way ANOVA and Scheffe. The songs exhibited traditional rhythms (3.3 or 4.4) and subject matter (nature, everyday life, and family). Some historical events such as the Korean war, and current phenomena such as TV, were also included. Sex but not age differences were found in recognition of the songs.

Purpose: The purpose of this study were to find out the degree of memory decline and to confirm its correlated factors in old adults. Method: The subjects consisted of 68 old adults over the age 65 who living in Busan. Data were collected by the interview method, using a structured questionnaire and the testing method on the memory performance. Results: The old adults' memory performances declined in tasks of immediately word recall, delayed word recall, and face recognition and increased slightly in word recognition over 2 years. However, there was only significant difference in delayed word recall task. The significant variables to predict memory decline were age, literacy, depression, locus, and strategy. Conclusion: The memory decline of old adults wasn't more serious problem than the perceived one. There needs to be some intervention programs to prevent memory decline for the elderly.

The purpose of this study was to extract accurate parameters of facial movement features using 3-D motion capture system in speech recognition technology through lip-reading. Instead of using the features obtained through traditional camera image, the 3-D motion system was used to obtain quantitative data for actual facial movements, and to analyze 11 variables that exhibit particular patterns such as nose, lip, jaw and cheek movements in monosyllable vocalizations. Fourteen subjects, all in 20s of age, were asked to vocalize 11 types of Korean vowel monosyllables for three times with 36 reflective markers on their faces. The obtained facial movement data were then calculated into 11 parameters and presented as patterns for each monosyllable vocalization. The parameter patterns were performed through learning and recognizing process for each monosyllable with speech recognition algorithms with Hidden Markov Model (HMM) and Viterbi algorithm. The accuracy rate of 11 monosyllables recognition was 97.2%, which suggests the possibility of voice recognition of Korean language through quantitative facial movement analysis.

Objectives: The purpose of this study was to provide basic data for suggesting the realistic plan for the prevention of induced abortion. We performed an analysis of a recognition and actual conditions of the induced abortion according to the marital status. Methods: Participants were 681 persons of 20 years of age or older who lived in 7 cities and provinces. The data was collected with a structured questionnaire. For data analysis, Chi-square test, t-test and stepwise discriminant analysis were utilized. Results: The results were as follows. When degrees of recognition were analyzed according to the marital status, married were found to have higher levels of recognition of induced abortion than unmarried. From comparison of the recognition, there were significant differences between married and unmarried in terms of the recognition of the law, premarital sex, sex consciousness, intention of induced abortion, knowledge of contraception. Conclusion: The above results showed that marital status was strongly related to the recognition of induced abortion. And measures for preventing the induced abortion, specially about 20 percents of risky unmarried, should be focused.

The computer programs based upon graphic user interface(GUI) became commonplace with the advance of computer technology. Nevertheless, programs for the visually-handicapped have still remained at the level of TTS(text to speech) programs and this prevents many visually-handicapped from enjoying the pleasure and convenience of the information age. This paper is, paying attention to the importance of character recognition in images, about the configuration of the system that converts text in the image selected by a user to the speech by extracting the character part, and carrying out character recognition.

In modern society, speech recognition technology is emerging as an important technology for identification in electronic commerce, forensics, law enforcement, and other systems. In this study, we aim to develop an age classification algorithm for extracting only MFCC(Mel Frequency Cepstral Coefficient) expressing the characteristics of speech in Korean and applying it to deep learning technology. The algorithm for extracting the 13th order MFCC from Korean data and constructing a data set, and using the artificial intelligence algorithm, deep artificial neural network, to classify males in their 20s, 30s, and 50s, and females in their 20s, 40s, and 50s. finally, our model confirmed the classification accuracy of 78.6% and 71.9% for males and females, respectively.

The purpose of the present research was to investigate cross-modal transfer, especially tactual-to-visual transfer in infancy and to study the relation between failure of cross-modal transfer performance and length of familiarization period. The subjects of this study were 60 infants, 10 boys and 10 girls at each level: six, nine, and twelve months of age. All were normal, healthy, full-term babies. The mothers' educational achievement was controlled at more than 12 years of schooling. There were two separate experimental conditions, one 30-sec and one 60-sec familiarization period. Each experimental condition consisted of a tactual familiarization and a visual recognition memory test. Each child was presented with these 2 sets of cross-modal stimuli in one of the 2 experimental conditions. Infants' visual responses in the visual recognition memory test were videotaped for 20 seconds. Visual fixation time to novel and familiar stimuli was observed throughout the test. The data was analyzed with t-test, percentage of total fixation time to novel stimuli, and ANOVA. The results showed that: 1) Significant differences were found in the cross-modal transfer performance from touch to vision between the 3 age groups. This is, 6 and 9 month old infants didn't show cross-modal transfer in the 30-sec condition, but 12 month old infants did show cross-modal transfer in the 30-second. 2) In all 3 age groups, no significant differences were found in cross-modal transfer performance between the two conditions.

Purpose: This study was to identify the state of recognition and experience of love, sex knowledge and self-esteem targeting girls who attended middle and high schools. Method: Data was collected from 391 girls of middle and high schools from Aug. 2004 to Nov. 2004. The collected data was analysed through t-test, and ANOVA. Result: The average age of the girls of this study was 16.9 years, and 31.6% of them discussed sex with their parents. The girls' experiences with love were hand-holding(80.8%) the most, and shoulder to shoulder(68.5%), arm in arm(67.8%), hugging(57.0%) and kissing(37.9%) in sequence, while coitus and pregnancy appeared in 0.8% of the cases. The score of sex knowledge was 68.8 and self-esteem was 74.4. Self-esteem was related to age and discussing sex with their parents. Conclusion: As the results above show, the majority of girl-students were mostly knowledgable about friendship and love expressions. At school and home, society's support and encouragement are required so that sex education at a young age and a positive self-concept may be formed.
