The objective of this study is to induce the primary characteristics of phenylketonuria in infant rats during the first 2 weeks after birth. The critical biochemical parameter in the development of phenylketonuria is the elevation of plasma phenylalanine while tyrosine is maintained at a relatively low level. A PKU-like condition was induced in infant rats during the first 2 weeks after birth using a modification of our previously published procedure for the development of a temporary (1 to 3 days) PKU-like condition. Phenylalanine was administered by stomach intubation every 6 hours (starting at 6:00 a.m.) at a dose level of 400mg per kg body weight (after birth-day 2 thru 5) and 500mg per kg body weight (day 6 thru 14). Amethopterin was given at 0.00625 or 0.0125mg per kg body weight (day 3 thru 14) and p-chlorophenylalanine at 50 mg per kg body weight (day 5 thru 14) at 9:00 a.m. and 9:00 p.m. At the times measured (6,10 and 14 days) plasma phenylalanine/tyrosine (P/T) ratios were elevated from a normal value of the or less to values ranging from 6 to 15. During the second week after birth a staggering gait, abnormal stance and decreased social behavior were also observed. None of these PKU-like characteristics were apparent in the three control groups receiving (a) no phenylalanine or inhibitors, (b) phenylalanine alone, or (c) inhibitors alone. The establishment of these primary biochemical characteristics of phenylketonuria by stomach intubation of phenylalanine and a combination of low dose levels of enzyme inhibitors to infant rats provides an experimental system which should he valuable for extensive biochemical, histological and behavioral studies in phenylketonuria.

The present study was to investigate the teacher's and the mother's beliefs about literacy acquisition and to analyse differences between them The subjects for this study were 134 teachers and 174 mothers of the kindergarten and daycare centers. The 25-item questionnaire constructed by Westwood, Knight and Redden(1997) was used in this study with a slight modification. Collected data were analyzed by one-way ANOVA to verify the differences of the teacher's beliefs according to an academic background and a career, and mother's according to an academic background and an occupation, and compared by t-test to verify the differences of the teacher's and mother's beliefs. The major findings were the most teachers and mothers showed balanced approach: more skill-based about reading than writing. The university graduated teachers took more meaning-based, child-centered approach than finisher of caregiver training center. According to career, more the experienced kept more skilled-based approach. In case of the mother, the university and graduated school graduates took more meaning-based, child-centered approach than finisher of college and High school. According to occupation, more the professional kept more meaning-based approach. Finally there were no meaningful difference in an income and mothers' age. And teachers took more meaning-based, child-centered approach than mothers. Especially about writing, teachers kept much more meaning-based approach than mothers.

The purpose of this study was to analyze the types and meanings of calligraphy presented in modern fashion design. Calligraphy refers to beautiful handwriting or fine penmanship in the West, and handwriting with brushstrokes in the East. The expression patterns being used at present can be divided into three categories. Legible calligraphy is focused on readability more than embellishment. Decorative calligraphy places its importance on decoration at the expense of practicality. The third type, harmonious calligraphy, pursues decorativeness and legibility at the same time. Each of these types of calligraphy is expressed in modern fashion with its own purpose: calligraphy for conveying emotional messages, calligraphy as a special brand image, and calligraphy as an expression of formativeness. The first, calligraphy for conveying emotional messages, is used with characters that are familiar to the public. Calligraphy of this type delivers messages confined emotionally to the conscious world, harmonizing calligraphy with words, or expressing readability filled with purity and delight. Second, calligraphy as a special brand image refers to transmitting a distinctive brand image from other companies through employment of a design motive or pattern by expressing the brand logos or names of designers. Third, calligraphy as a expression of formativeness has the function of shaping expressions as motives or patterns, avoiding meanings of words or phrases. It can be represented by the abbreviation or modification of words, or arranging words in different shapes, harmonizing the words with the clothing construction and atmosphere of the other images.

GPS is widely used for positioning applications and attitude of a vehicle can be found also with multiple antennas. However, extremely weak signal level prevents GPS from indoor operation. DR with accelerometers and gyros and landmark based localization method used for indoor applications increase complexity and cost. In this paper, a simple but very efficient ultrasound based attitude determination system which determines both position and attitude in WSN is given. The range between transmitter and receivers are measured using the arrival time difference between ultrasound and RF signal. The 3 dimensional positions can be found using more than 3 range measurements. Furthermore, if more than 2 transmitters are used, the attitude can be determined using the baseline vectors obtained by differencing transmitter and receiver positions. The prototype system is implemented to evaluate the performance of the proposed method. In addition, an error analysis shows the relation between the attitude error and basel me length, quality of measurement and orientation of a vehicle. The static and dynamic experiments performed by micro mobile robot shows accurate position with less than 1.5cm error and attitude with less than 1 degree error can be obtained continuously with 20cm baseline. It is expected that these results can be adapted without modification to indoor applications such as home cleaning robot and autonomous wheelchair maneuvering.

Teenagers are fast in growth and very sensitive. They are more interested in appearance and clothing and they use it as a method of expressing themselves. Thus they show different attitudes toward clothing. This study is to survey teenagers' attitudes toward clothing, especially school uniform and to understand their psychological characteristics about clothing. The purpose of this study is to provide useful data in designing teenagers' school uniform which can serve to fulfill their clothing desire and beautiful school life. The results of this study can be summarized as follows. As of paradigm in clothing, they value individuality, economical efficiency, practicality, fashion, and conformity of clothes in the order of importance. They considered individuality value the most important. Students' preference of school uniform is not positive over all. About 60% of students support wearing uniform, and 50% like wearing uniform on the way to school. The reasons for wearing school uniform are psychological stability and economical efficiency. They think school uniform is well fitted for the student position and don't have to care about clothing if they wear school uniform. 63% of them prefer wearing famous brand but they think the price is too high. Comparing with male student, female students place more value on latest fashion and are more likely to purchase brand object than male students do. Female students have more experience in modification of school uniform than male students do. Based on the result of this study, we need to understand the students' attitudes toward school uniform and to accept demand of teenagers' idea in production of school uniform.

Sleep is an essential component for health and the quality of life of individuals, and is affected by multiple factors. Thereby, sleep impairment is known to be frequent even in healthy subjects. The purpose of the study is to compare sleep patterns and related factors between healthy young and old adults and to identify aging effects upon sleep in a cross-sectional way. The survey questionnaire was developed by translation and modification of two well-known sleep questionnaires which were originally developed by Monroe(1967) and Ellis, et al. (1982). Discussion with experts and pilot study were completed to finalize the contents of the questionnaire that was used in this study. Results are as follows : 1. Sleep complaints were lower in older adults. 2. The most frequent variables that explain sleep satisfaction were feeling rested in the morning in the older adults and feeling rested and failing asleep within five minutes in the young adults. 3. Regarding sleep-disturbing factors, physical factors were more frequently reported in the older adults and environmental factors are reported more frequently in the young adults, and there was no difference related to the emotional factors between the two groups. 4. Young adults were practiced strategies for better sleep more often than the older adults, and they were mainly in-home activities just before sleep. 5. Sleep patterns which change with aging were as follows : going to bed and waking up earlier : not staying in the bed long after waking up ; getting harder to fall asleep ; frequent arousal after sleep onset ; getting harder to go back to sleep after arousal during night sleep. From the results of this study, it can be concluded that sleep and related factors of the young and the older adults are different. Also, sleep patterns change with aging and those changes seem to be negative for sleep in the elderly. Repeated studies are needed to establish more concrete information regarding sleep patterns. In addition, further research is needed to develop more reliable, valid, and feasible sleep measure tools, and to develop and evaluate nursing interventions.

Purpose: The prescription drug list for primary treatment by community health practitioners has been maintained for 30 years without any modification. Thus, this study will suggest an improvement scheme of prescription drug list for primary health care posts through an analysis of drug use in those posts. Methods: A questionnaire survey was implemented with community health practitioners from April to June in 2012. A total of 1,249 copies were analyzed. As for the databases of drug use in the integrated information, a total of 154,229 diagnoses selected in the method of stratified cluster sampling from 39 primary health care posts' data were analyzed. We consulted some experts about the prescription medication list, and referred to the medication information on-line home page for up-to-date drug information. Results: This study ultimately suggests 77 prescription drug items for primary health care posts by eliminating 35 items and replacing 1 item from the original list, and adding 4 items to it. Conclusion: This study will provide basic data for revising the prescription drug list in primary health care posts by periodically reflecting adverse effects in the existing drugs, demographic and environmental changes, and development of new drugs.

This study is carried out to develope parent education methodology by analysing "${\acute{E}}cole$ des Parents" of France. To study this subject we approach by following three methodes. Firstly, we examined bibliographes to find out motivation of initiative caused from hystological and sociological circumstance. Secondly, to analyse chronological developement and modification of "${\acute{E}}cole$ des Parents" we interviewed with three periods of persons : founder, developer and actually working animators. In addition, we riviewed three hundred eighty volumes of $\underline{{\acute{E}}cole\;des\;Parents}$, from first jurnals to october, 1993. Thirdly, this study were approached by participant observation in actual activities, and by analyse statstical records and subject of articals. In results, we noticed following caractors working in french parent education system. All the regional "${\acute{E}}cole$ des Parents" are alined with "$F{\acute{E}}d{\acute{E}}ration$ Nationale des ${\acute{E}}cole$ des Parents et des ${\acute{E}}ducateurs$"(F.N.E.PE.) in educational polish but activities and methodes of education are independant with F.N.E.P.E., and in most different regional "${\acute{E}}cole$ des Parents" focussed the educational programes to the middle class families in economic point of view. these programes adjust very rapidly systematicaly to social requirment due to successed intensive research. Mordern programs tend to contain all members of family in stead of targeting only maternal members. Methodes of education by lectures and speechs only to deliver information also replaced by discussion, forum and groop animation to induce self-correction. We propose that the systems of FNEPE can be ideal models to solve many actual problems facing in Korean parent education systemes.

Purpose- The purpose of this study was to compare the fit of two prototype liquid cooled vests using a 3D body scanner and accompanying software. The objectives of this study were to obtain quantitative measurements of ease values, and to use these data to evaluate the fit of two cooling vests in active positions and to develop methodological protocol to resolve alignment issues between the scans using software designed for the alignment of 3D objects. Design/methodology/approach- Garment treatments and body positions were two independent variables with three levels each. Quantitative dataset were dependent variables, and were manipulated in 3x3 factorial designs with repeated measures. Scan images from eight subjects were used and ease values were obtained to compare the fit. Two different types of analyses were conducted in order to compare the fit using t-test; those were radial mean distance value analysis and radial distance distribution rate analysis. Findings- Overall prototype II achieved a closer fit than prototype I with both analyses. These were consistent results with findings from a previous study that used a different approach for evaluation. Research limitations/implications- The main findings can be used as practical feedback for prototype modification/selection in the design process, making use of 3D body scanner as an evaluation tool. Originality/value- Methodological protocols that were devised to eliminate potential sources of errors can contribute to application of data from 3D body scanners.
