The purpose of this study is to analyze the effects of the degree of preparation for old age and perception of successful aging on the life satisfaction of middle-aged women. The participants in this study were 300 women ranging in age from 35 years to 65years who reside in Seoul, Gyeonggi-do, and other cities. Two hundred eight self-reported questionnaires were used for final analysis by SPSS WIN14. The major results of this study were as follows: First, there were differences in the degree of preparation for old age of middle-aged women by age, academic career, income, area, and religion. Second, there were differences in self-efficacy in the perception of successful aging by academic career, an income, and area. Third, there were differences in the degree of life satisfaction of middle-aged women by academic career and income. Finally, the most effective variables on the degree of life satisfaction were the degree of preparation for old age, perception of successful aging, and income. Consequently, to improve the life satisfaction of middle-aged women, social groups, local self-governments, and the government have to educate women on economic management for preparation for old age and human relationship progress programs, as well as promote healthy leisure cultures.

Surveying perception of majors to students of Department of dental technology 433(48.3%) and Department of dental hygiene 463(51.7%), and their sex rates 272 (30.4%) for males and 624 (69.6%) for females, 896 examines in total, have let us to know the level of student's perception of their majors and now able to adjust the level of major's lectures and maximize the ability to study has brought these conclusions. 1. Although the hometowns of students had similar rates between large and small cities disregarding their departments, the type of highschool had differences for the academic highschool graduators were the most. Also, CSAT was the highest than other specialized types when entering. 2. Self selection considering employment percentage was the highest for the student's choice of selecting department of dental hygiene and dental technology. 3. For the satisfaction of school and education systems, "satisfied" and "normal" were as high as 74% in both department of dental hygiene and dental technology for school satisfaction, and 75%, 74% for satisfaction of environment from the two departments. 4. As for the satisfaction of department and environment, department of dental hygiene and dental technology both answered "satisfied" and "normal" the most, but in satisfaction of companions, they have shown relatively high satisfaction by answering "very satisfied" and "satisfied". 5. Difficulties of majors relating to the perception of learning, department of dental technology and dental hygiene both answered too much to memorize and hard to understand. 6. Department of dental technology's try for majors relating to the level of perception of learning have shown that they have high understandings in proportion to how much they try but for department of dental hygiene has shown not much differences. 7. Department of dental hygiene had higher stress than department of dental technology in studying majors and there were both some differences statistically.

The purpose of this study is to observe the age differences in safety perception among babyboomer, pre-elderly, and the elderly and to seek for countermeasures to overcome the risk. The data used for this study were from the 2008 Social Survey conducted by Administration on Statistics, Korea. The data were divided into three different age groups such as babyboomer, pre-elderly, and the elderly. Results showed that overall safety level of the society, safety perception of others and oneself, current social safety level compared to 10 years ago, social safety level after 10years, awareness of safety among different social fields, and the rank among the list of factors that lead to social insecurity appeared to differ according to the three different age groups. The awareness of safety for the elderly group was not higher than babyboomer and pre-elderly groups. Age differences in safety perception reflected the times and experiences the same age cohort went through. Countermeasures for security should be developed by considering the characteristics of the generations and different age groups.

Background and Purpose: Episodic memory is a system that receives and stores information about temporally dated episodes and their interrelations. Our study aimed to investigate the relevance of episodic memory to time perception, with a specific focus on simultaneity/order judgment. Methods: Experiment 1 employed the simultaneity judgment task to discern differences in time perception between patients with mild cognitive impairment or dementia, and age-matched normals. A mathematical analysis capable of estimating subjects' time processing was utilized to identify the sensory and decisional components of temporal order and simultaneity judgment. Experiment 2 examined how differences in temporal perception relate to performance in temporal order memory, in which time delays play a critical role. Results: The temporal decision windows for both temporal order and simultaneity judgments exhibited marginal differences between patients with episodic memory impairment, and their healthy counterparts (p = 0.15, t(22) = 1.34). These temporal decision windows may be linked to the temporal separation of events in episodic memory (Pearson's ρ = -0.53, p = 0.05). Conclusions: Based on our findings, the frequency of visual events accumulated and encoded in the working memory system in the patients' and normal group appears to be approximately (5.7 and 11.2) Hz, respectively. According to the internal clock model, a lower frequency of event pulses tends to result in underestimation of event duration, which phenomenon might be linked to the observed time distortions in patients with dementia.

The purpose of this study was to investigate if there were any differences between fashion models and female college students' body cathexis and to examine the perception of their body form and satisfaction of clothing fit according to height, weight and body type. For this study 378 people, including 113 fashion models and 265 female college students were analyzed. Means, t-test and ${\chi}^2$-test were used in data analyses. Significant differences were found between fashion models and female college students' body cathexis. For instance fashion models were more positive about their bodies especially concerning height. Fashion Models and female college students differed significantly in perception of their body form according to weight and body type. Perhaps they have another criteria. Fashion Models and female college students differed significantly in satisfaction of clothing fit according to weight and body type. The taller and Thinner, The higher satisfaction of Clothing fit.

This paper tests whether the VOT (Voice Onset Time) contributes to the perception of tense and plain stops in Korean in the initial position. Previous studies have yielded opposite results regarding the role of the VOT in the distinction of these two stop categories. One the one hand, Lisker and Abramson (1964), Kim (1965), and Han and Weitzman (1970) suggest that the Korean plain and tense stops exhibit overlapping values of VOT and thus that, unlike many other languages, the VOT fails to serve as a cue to separate these stop categories. On the other hand, Silva (1991, 1992), and Lee (1991, 1994) use similar methods, but find that the VOT serve as the cue. In this study, the differences in the acoustic measurement with respect to the VOT of Korean plain and tense stops in initial prevocalic position will be tested preceptually, in seeking to determine whether these acoustic differences are used by listeners to distinguish these two stop types.

The main purpose of this study is to investigate whether Korean learners can use the vowel duration cue to distinguish voicing contrasts in word-final consonants in English. Given that the Korean group's performance on the auditory task was much better than their performance on the identification task or on the production task, we conclude that the AX discrimination task makes contact with a different layer of perception. In particular, the AX discrimination task can be done at the auditory or phonetic level, where differences in vowel length are still encoded in the representation. In contrast, the identification and production tasks are probing the mental representation of vowel length and voicing. It was also founded that Korean speakers stored neither vowel length nor voicing in memorized representations and did not internalize the lengthening of the preceding vowel as a rule to differentiate the voicing contrasts of final consonants, even though they were able to detect the acoustic differences in vowel duration provided that they were tested in an appropriate task.

This paper examines the categorical labeling of lexical pitch accent contrasts in North Kyungsang and South Cholla Korean listeners. It focuses specifically on investigating whether the pitch accent perception of adults and children has a dialect-specific effect. To evaluate the development of perceptual identification, slopes, intercepts, and positions at categorical boundaries were computed using a logistic regression function. The results showed that differences in slopes and intercepts were significant between North Kyungsang child and adult listeners, but the same was not the case for the positions at boundaries. As far as South Cholla child and adult listeners were concerned, there was a significant difference in slopes, but not intercepts and positions at boundaries. In the present study, the comparison of intercepts and slopes at the boundaries indicated developmental differences between North Kyungsang adult and child listeners. This improvement in categorical proportion seems to be a result of developmental changes in categorical perception. For South Cholla adult and child listeners, however, perception of the non-native contrast becomes less categorical.
