The purpose of this study was analyze how korean adult women\`s swimming suit buying behavior varied according to consumer characteristics. Especially, it was intended to provide basic materials for swimming suit product development and quality improvement appropriate to consumer characteristics with a focus on product evaluation criteria. Questionnaire research was conducted for 850 adult women resident in Seoul, to whom questionnaire were distributed and who were asked to complete their questionnaires. 1. As for buying motive, of swimming suit buying behavior, it was shown that the highest proportion of adult women bought their new swimming suit because their old swimming suit was wornout and most adult women tended to buy their new swimming suit or their own will rather than at others\` suggestion. 2. As for the source of information at a time. of swimming suit purchase, adult women collected information from the product on display most and bought their swimming suit in a planned way in relation to the degree of purchase planning. 3. As for product evaluation criteria, adult women showed the high scores in order of the type and quality of material, activity and functionalism, dimensions and fitness. 4. In many cases actual swimming suit purchasers were the adult women who bought their swimming suit, and they used the department store or the large shopping center as the place of purchasing the swimming suit. Its reason was that the department store or the large shopping center had a diverse assortment of products. As for the degree of their travelling companion\`s influence, it was found that most adult women were influenced by their travelling companions when purchasing their swimming suits. 5. As for the level of satisfaction with swimming suit purchase, it was shown that adult women were generally satisfied with their swimming suit purchase. It was found that their level of satisfaction was higher in order of activity and functionalism, the type and quality of swimming suit materials, and ease in washing management while they showed the low level of satisfaction with price, the fastness of color to washing, light and detergents and durability.

The purpose of this study was to search and analyze the realities and needs of life long education, the necessity and perception of life competencies and the difference of competencies on experiences of education to support life long education system for adult learners in Busan and Ulsan. In this study, we conducted a questionnaire survey of 234 adult learners living in Busan and Ulsan. The results of this study were summarized as follows. First, adult learners perceived that life long education was very important to adults and appreciated an educational institution being managed by government. Second, adult learners thought that basic literacy competency and basic work competency were important and late fifties perceived that professional job is in important. Third, adult learners perceived that self directed learning and capacity of management are poor competencies. And they perceived that the government support adult learners who has economical difficulty. Forth, adult learners perceived that it was normal that 'professional job' and 'job transition abilities', 'women', 'the middle aged and old','the unemployed' and' low incomers' perceived that they have poor level. Fifth, according to the results of ${\chi}^2$ test for determining the statistical significance of differences in experience in lifelong learning among adult learner groups divided by their individual background, significant differences were observed in a few competencies(p<.05, p<.01).

This study was performed to examine the emotion expectations and explanations of four participants(an actor, a recipient, a child observer, and an adult observer) in moral, social-conventional, and personal rule transgression situations. Six vignettes describing the rule transgressions were presented to 200 children who were either five or seven years old. The children were asked to predict and explain each participant's emotions. The children's emotion expectations were different depending on the domain of the rule transgressions and on the type of the participant. The actors were predicted to feel happy during all transgressions, while the recipients and two observers(a child and an adult) were predicted to feel unhappy. The seven-year-old children attributed more happiness to the actors, and more negative affect to the recipients compared to the five-year-olds. This result was inconsistent with the previous findings that older children attributed more happiness to actors. This finding was discussed in relation to the 'happy victimizer'. Some categories of emotion explanations were differentiated according to the domain of rule transgressions. The personal rule transgressions, newly defined and examined in this study, were judged to be less serious than the moral rule transgressions in terms of the intensity of the negative affect.

The present study was conducted to investigate the structural changes in rat cornea. Sixty eyes from one-day-old uneyed rats, fourty eyes from 4-weeks-old rats, and foully eyes from 10-weeks-old adult rats were used. With the increase of age, the epithelial layer was thickened by the addition of new successive cellular layers. Then, the new-born rat's epithelial cells formed a pentagonal shape, and the quality of decidual cells showed a high electron-density, although the boundary between cells was distinctive. The newly produced cells showed a low electron-density so that there was the distinctive difference between light and darkness. In Bowman's layer, collagen fibrils demonstrate a regularly arranged structure along with the age. In stroma's layer, the density of keratocytes was decreased and thereby Progressively flattened during the development. The collagenous layer of the adult rats was more distinctive than that of the new-born rats in a form of parallel alignment running vertically and horizontally.

Objectives: The purpose of this study was to investigate whether the age factor would be related with stability of mandibular setback surgery for patients with mandibular prognathism. Materials and Methods: We compared the relapse patterns of 47 patients divided into three age groups (termed younger, adult, and older). The younger group consisted of patients between 15 and 17 years old; the adult group was made up of patients between 21 and 23 years old, and the older group was made up of patients more than 40 years old. The positional change of B point was evaluated at preoperative, postoperative, and follow-up states. Results: The horizontal relapse ratio was 21.7% in the younger group, 15.3% in the adult group, and 15.7% in the older group. Although relatively higher degrees of relapse were found in the younger group, this increase was not statistically significant. Spearman's correlation analysis was performed to explore other factors contributing to relapse. We subsequently found that the amount of relapse was related to horizontal setback. Conclusion: Although the degree of relapse in younger patients is not significant;y higher compared to other groups. The major contributing factor to relapse after sagittal split ramus osteotomy is amount of setback rather than age when the surgery was performed to patients over than 15 years of age.

Background: In recent events of the coronavirus disease 2019 (COVID-19) pandemic, computed tomography (CT) scans are being globally used as a complement to the reverse-transcription polymerase chain reaction (RT-PCR) tests. It will be important to be aware of major organ dose levels, which are more relevant quantity to derive potential long-term adverse effect, for Korean pediatric and adult patients undergoing CT for COVID-19. Materials and Methods: We calculated organ dose conversion coefficients for Korean pediatric and adult CT patients directly from Korean pediatric and adult computational phantoms combined with Monte Carlo radiation transport techniques. We then estimated major organ doses delivered to the Korean child and adult patients undergoing CT for COVID-19 combining the dose conversion coefficients and the international survey data. We also compared our Korean dose conversion coefficients with those from Caucasian reference pediatric and adult phantoms. Results and Discussion: Based on the dose conversion coefficients we established in this study and the international survey data of COVID-19-related CT scans, we found that Korean 7-year-old child and adult males may receive about 4-32 mGy and 3-21 mGy of lung dose, respectively. We learned that the lung dose conversion coefficient for the Korean child phantom was up to 1.5-fold greater than that for the Korean adult phantom. We also found no substantial difference in dose conversion coefficients between Korean and Caucasian phantoms. Conclusion: We estimated radiation dose delivered to the Korean child and adult phantoms undergoing COVID-19-related CT examinations. The dose conversion coefficients derived for different CT scan types can be also used universally for other dosimetry studies concerning Korean CT scans. We also confirmed that the Caucasian-based CT organ dose calculation tools may be used for the Korean population with reasonable accuracy.

A difference in ethanol metabolism between premature and young adult rats was examined. Female SD rats, either 4wk or 12wk old, were injected with a single dose of ethanol (1.5g /kg) through jugular vein and the blood ethanol level was monitored for 300 min using a gas chromatographic method. Reduction of blood ethanol level per unit of time was less and the area under the blood concentration-time curve (AUC) was significantly greater in young adults compared to premature rats. Activity of hepatic alcohol dehydrogenase was not influenced by the age increase. Total cytochrome P-450, cytochrome $b_5$. or aminopyrine N-demethylation was not different between premature rats and young adult rats. However, p-nitrophenol hydroxylation and p-nitroanisole O-demethylation activities were significantly higher in premature rats. The relative liver weight was 45% greater in premature rats leading to an overall increase in ethanol metabolizing activity in these animals. The results indicate that the reduction in ethanol elimination in young adult rats appears to be mostly associated with the decrease in relative liver weight as the age of animals increases.
