The purpose of this study was to identify the effect of three clothing cues(neutral tone, skirt width, and skirt length of dress) on the impressions of females. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 20 color pictures manipulated with three clothing cues by drawing. The 7-point scale designed for visual evaluation of impression formation about females included 29 bipolar adjectives. The subjects were 240 undergraduate female students in Chinju city. The results of this study were as follows: By analyzing the impression of female figures by neutral tone, skirt width, and length, five factors including ability.activity, elegance, attractiveness, concentration of attention, and tenderness were identified. Among these factors, ability.activity and elegance were proved to be more important. Each impression of neutral tone with skirt width. length have significant effects on tenderness. Each impression of skirt width.length with neutral tone have significant effects on ability.activity.

The purpose of this study is to analyze the process of creative science problem solving (CSPS) in elementary school students. To do this, 6 graders (n=9) at a elementary school in Seoul were participated. In this study, fixed eye-tracker with 250 Hz sampling and observation camera were used. The results of this study, the students with higher ability to solve creative science problems had a slower saccade, and had more visual attention on core clues and a greater number of eye changes. Therefore, students with higher ability to solve creative science problems showed more effective eye movement and faster information processing to solve problems. The CSPS types of elementary students were classified as 'declarative knowledge type', 'procedural knowledge type', 'conditional knowledge type', 'knowledge lack type'. Because each type appears to be complementary, CSPS process for elementary students who have integrated the four types was devised. The results of this study can be used as basic data for understanding elementary school students' CSPS and will help to develop and guide creative science teaching and learning programs useful to elementary school students and science gifted students.

Orthogonal Frequency Division Multiplexing (OFDM), which employs orthogonal overlapping subcarriers to modulate the signals, has been attracted much attention in recent time as a favorable option for future generation wireless networks due to its ability to overcome many impairments in wireless channels. Since OFDM is a multi-carrier system adaptive modulation techniques can be effectively and efficiently used to enhance the system performance in terms of both BER and overall system capacity. This paper discusses a COFDM-CDMA system with adaptive modulation schemes for future generation wireless networks.

The inverse relationship between dietary flavonoids consumption and cardiovascular diseases may be associated with the ability of flavonoids to attenuate LDL oxidation. Although flavonoids have been employed to prevent against LDL oxidation, their pro-oxidant effect also deserves an attention in respect to untoward property. (omitted)

Deoxyribonucelic acid (DNA) molecules have a huge molecular weight so that DNA was reported to be a promising natural polymer to give durable films. Among many applications of DNA, the authors focused their attention on separation membranes derived from DNA because membranes will play an important role in environmental and energy related processes. DNA-polyion complex membranes were prepared from DNA and corresponding polycations. The DNA-polyion complex membranes showed chiral separation ability toward racemic amino acid mixtures.

Digit recognition based on backpropagation neural networks, as an important application of pattern recognition, was attracted much attention. Although it has the advantages of parallel calculation, high error-tolerance, and learning capability, better recognition effects can only be achieved with some specific fixed format input of the digit image. Therefore, digit image preprocessing ability directly affects the accuracy of recognition. Here using Matlab software, the digit image was enhanced by resizing and neutral-rotating the extracted digit image, which improved the digit recognition capability of the backpropagation neural network under practical conditions. This method may also be helpful for recognition of other patterns with backpropagation neural networks.

Non-viral vectors, including lipid- or polymer-based systems, have attracted much attention to date as a gene delivery vehicle, due to safety issues with viral vectors. Chitosan, a naturally existing cationic polymer, has shown great potential as a gene delivery carrier, as it has low immunogenicity and toxicity, excellent transcellular transport ability, and is relatively easy to chemically modify. This review summarizes and discusses the general features of chitosan and its applications as a delivery carrier of DNA and RNA.

Objective : The purpose of this study was to identify the effect of Interactive Metronome (IM) training on postural control and hand writing performance of children with Attention Deficit Hyperactivity Disorder (ADHD). Methods : Participant was a third grade elementary school student diagnosed with ADHD. ABA design was used and a total of 30 sessions were held for 3 sessions every week for a total of 10 weeks. In the intervention period, IM training was conducted for 40~50 minutes before intervention for writing, and the writing task was carried out. We evaluated the handwriting legibility and speed. Before baseline A and within a month after A' phase, Clinical Observation of Motor and Postural Skills (COMPS) was evaluated to examine the changes in postural control of the student. Results : After the IM intervention, the postural control of the student improved in the score of slow movement, finger-nose touching, and asymmetrical tonic neck reflex. The handwriting legibility and speed has also tended to increase during the intervention period, but it has not significantly changed. Conclusion : This study could be used as an evidence that the IM training aimed at postural control and handwriting ability could enhance the ability to improve postural control and thereby provide fundamental knowledge for future studies.

The purpose of the study is to test structural relationship of subjective health, ability to work, participation on economic activity, and life satisfaction among the elderly. Recently, societies have tried to lessen a social burden and alleviate negative perceptions of the elderly through some perspectives such as productive aging and active aging. In these perspectives pay attention to health and social participation to improve quality of life. Subjects were 3,392 elderly people over the age of 65 from 10th Korea Welfare Panel Study. The main results of the study are as follows. First, subjective health, ability to work, and participation on economic activity had a direct effect on life satisfaction among the elderly. Second, subjective health had a statistically significant effect on ability to work and participation on economic activity. Finally, avility to work had a positive effect on participation on economic activity. Based on the results of the analysis, this study suggested that health and work related factors should be considered as the important factors to improve the life satisfaction among the elderly.

The early stage of Korean language education was to understand grammar. However, recent Korean language education aims to improve expressive ability for smooth communication. Hence, educational drama for education has gained attention as one of the effective ways of improving communication skills. Educational drama provides an actual conversational situation in which one can use appropriate words and grammar depending on the situation. Non-verbal expression such as body language and facial expression could be picked up so one also improves one's communicative abilities naturally. This means that educational drama shares Korean language education's goal of improving communicative ability. Moreover, the student becomes the core of the activity and finds solutions through cooperation with others, and this also helps improve social skills and self-esteem. This thesis covers methods of having interviews, re-writing texts to scripts, writing up post-script by imagining the following text, role-playing, and improving expressive ability by debating educational theatrical techniques. To make these activities successful, good quality VOD and learning materials shall be developed and used. Also, efficient training programs shall be created so that teachers make use of what they learn and improve their teaching skills.
