Background: It is thought that drug use of parents is related to that of young children. The status of drug among young children's parents and a correlation of with parents and their children on drug use was surveyed by questionnaire. Method: The questionnaire is composed of 34 items, and the data was collected by 108 parents of young children from March to April of 2012. Results: On the basis of the analysis results, the following conclusions were drawn. About half of parents thought the minimum use of drug was better for health, and 44% parents thought drug is essential for cure. When parents had queries on prescription, they mostly consult with doctors and pharmacists. Most parents had a household medicine. A fever reducer was the most common household medicine (92.5%). They pick the household medicine by consulting with pharmacist. Parents usually checked the expiration date of drug before they use and they dumped the drugs when the expiration date was due (82.4%). Over half of young children and their parents took a dietary supplements. They got an information about a dietary supplement by associates (30.5%) and internet (19.4%). Most parents tried to follow the directions as prescribed. However, more than half of the parents stopped taking the drug when the symptoms disappeared. Conclusion: Drug use of parents and that of young children had a very strong positive correlation, suggesting that correct drug use of parents have an impact on their young children's drug use.

This study investigates the far-field noise from three Falcon 9 vehicle launches from Vandenberg Air Force Base, CA, USA, as measured from the same location within the nearby community of Lompoc. The overall sound pressure levels for the three launches are shown to be similar, but some differences in the early launch period are thought to be weather-related. The peak directivity angle in overall level is approximately 65 deg, which is consistent with horizontally-fired, static rocket data. For the third launch, waveforms and spectra are analyzed for different events during the launch sequence. The measured spectral bandwidth decreases with time, but spectral levels remain above the ambient noise throughout the main-engine firing. Additionally, late-launch phenomena observed in the data appear to be correlated with main-engine cutoff and second-stage engine start.

This study was conducted to find out how young black-tailed gulls (Larus crassirostris) recognize adult voice signals after hatching. For the experiment, adult voice recorded in the natural environment was played back at controlled intervals and intensity (dB) to 15 young gulls that were artificially hatched in the laboratory. The chirirah call frequency of young gulls increased as the intensity of the mew call increased. The chirirah response of the control group was highest to the mew call at intervals of 1.8s. The adult long ca11 and alarm call also showed similar results to the mew call when the interval and intensity were manipulated similar to the mew call. Based on the results of this experiment, it is assumed that the young black-tailed gulls recognize adult voice signals based on the simple structure of adult voice signals, that is, the interval and intensity of the voice.

Several aspects of the conscious about somatotype were analized for the young females and the middle-aged womenhood of Korea. the questionaires were sent to sample of students of university and the middle-age womenhood in Kwangju. the data from 233 respondants were analysed in using frequency, crosstabs and t-test. The results were as follows: 1. Korean young females tend to have shorter and slimmer in trunk, taller in height and lighter in weight than somatotype of the middle-aged women. 2. Of the trouble of somatotype, young females tend to have much the trouble about the thickness of thigh and the middle-aged women tend to have much the trouble about the thickness of waist, hip. 3. Korean young females tend to have much the trouble of somatotype than that of the middle-aged women. 4. And then, most young female had strong aspiration to be slim about somatotype than that of middle-aged women.

The study aims to analyze Thomas Young's problem solving processes of analogical reasoning during the formation of the interference theory of light, and to draw its implications for secondary science education, particularly for enhancing creativity in science. The research method employed in the study was literature review of the papers which Young himself had written about sound wave and property of light. His thinking processes and specific features in his thought that were obtained through analysis of his papers about light are as follows: Young reconsidered Newton's experiments and observations, and reinterpreted Newton's results in the new viewpoints. Through this analysis, Young discovered that Newton's interpretation about his own experiments and observations was faulty in a certain point of view and new interpretation is necessary. Based on the data, it is hypothesized that colors observed on thin plates and colors appeared repeatedly on Newton's ring are appeared because of the effect of light interference. Young used analogical reasoning during the process of inference of similarity between sound and light. And he formulated an hypothesis on the interference of light through using abductive reasoning from interference of water wave, and proved the hypothesis by constructing an creative experimental device, which is called a critical experiment. It is implicated that the analogical reasoning and experimental devices for explaining the light interference which Young created and used can be utilized for school science education enhancing creativity in science.

This study was conducted to examine the status of food consumption and nutrition intake of young adults according to food security using data from the Korea National Health and Nutrition Examination Survey (KNHANES) (2008~2018). A total of 10,655 young adults aged 19~34 years participated in the study. The subjects in the moderately/severely food insecure group consumed less fruits, vegetables, meat, nuts and seeds than those in food secure/mildly food insecure group after adjusting for confounding factors. The moderately/severely food insecure group significantly decreased mean adequacy ratio (MAR) and nutrient adequacy ratio (NAR) for protein, vitamin A, riboflavin, niacin, vitamin C, calcium, phosphorus and iron compared to the food secure/ mildly food insecure group. The percentages of the participants consuming a daily diet with carbohydrate, protein, vitamin A, thiamin, riboflavin, niacin, vitamin C, phosphorus and iron less than the estimated average requirement (EAR) increased in the moderately/severely food insecure group compared with the food secure group. This study suggested that the nutrition intake of young adults was related to food security status. These findings can be used as basic data for developing nutritional policies for young adults.

The purpose of this study was to examine Korean young children's acquisition of honorific expressions. The participants of the present study were 297 young children (ages 3-5 years) from Kyunggi province. The results of the study showed that young children acquire honorific markers in the order of hearer-honorific expressions, subject-honorific expressions, and then object-honorific expressions. Five-year old children acquired at least 75% of the hearer-honorific expressions. The result can be explained by the fact that most of them were used in greetings. Even though more than 90% of five-year old children acquired the subject-honorific marker si, the acquisition rates of subjecthonorific nouns and subject-honorific verbs were less than 10%. Finally, the acquisition rates of objecthonorific expressions were less than 20%, with the exception of the object-honorific noun ce. The results of the study suggest that educational programs should be developed in order to facilitate the acquisition of honorific markers in young children.

This study examines the motivation, opportunity, and ability in the use of the internet by comparing young and aging consumers in the essential infrastructure of an information oriented society. Previous studies have conducted surveys about using computers and the internet instead of measuring the digital divide by using multilateral approaches; however, this study examines digital divide in terms of motivation, opportunity, and ability. Results suggested age, gender, and education level influenced motivation, opportunity, and ability in the use of the internet by consumers; in addition, the motivation and ability were different depending on occupation. The results show that the digital divide was mainly influenced by motivation and ability in offering a difference between the two groups of young and aging consumers, This study contributes to illuminate the differences between young and aging consumers to use the internet and to suggest implications in the perspectives of motivation, opportunity, and ability.

The complex Young's modulus of a viscoelastic material can be obtained as a function of frequency from the measurements of relative motion between the two ends of a bar-type specimen. Non-resonance method is usually used to obtain the complex Young's modulus over wide range of frequency including resonance points, while in resonance method information at resonance frequencies only is used. However, the complex Young's modulus obtained by the non-resonance method is often unreliable in the anti-resonance frequency regions because of the measurement noise problems. In this study, the effects of the random measurement errors on estimating the complex Young's modulus are studied in the aspect of sensitivity, and how to obtain the reliable frequency region for a given measurement error level is shown. The usable frequency regions in determining the complex Young's modulus are represented by a non-dimensional parameter formed with the wave length and specimen length.
