Purpose: This study is intended to provide easy explanations needed to ensure correct understanding of the notification of health education curriculum revised in 2008, health education curriculum at middle and high schools as well as their effective application at schools. Teachers of health lessons can provide better guidance for their classes only when they are well informed of intent and direction of health lessons sought after by the nation, objective and systematic content of health lessons, teaching methods, characteristics of teachinglearning materials and their evaluation. The contents of the guide have been sufficiently detailed and clarified in such a way that can increase understanding of school health education as pursued by the nation. Methods: This is reported research as its contents have been finalized through analysis of documentary records concerned with health education available at both home and abroad, a council of health education experts and public hearings organized for extensive collection of opinions from professor and teachers. Results: The guidebook has been prepared in 5 areas covering respectively "background of revision to health education curriculum", "how health education curriculum has been changed over time", " focus on health education curriculum", "explanations on health education curriculum" and "comparison of new and previous curriculum". Also developed were key initiatives on 6 health related subjects. Conclusion: The greatest significance of this research lies in the fact that it has come up with the first guide book for health education ever prepared in our history. It is also meaningful for the guide book to enable teachers to teach their classes better by providing them with easy interpretation of the contents notified by the government and to have set guidelines for directions in which health of our youths should be promoted. Since this is the first work, continuous research and development should further be carried out in the future.

Good snack consumption behaviors are important among elementary students because snack provides additional energy and nutrients and because good dietary behaviors should be formed during early stages of life. This study investigated, among elementary school students, 1) snack consumption behaviors, 2) snack-related nutrition knowledge level, and 3) relationships between snack behaviors and snack-related nutrition knowledge. A convenience sample (N = 372), drawn from 5th and 6th graders of an elementary schools in Siheung-si, Gyeonggi-do, completed a pre-tested questionnaire. More than 85% of the participants snacked more than once per week. Most (77%) had their snacks at home. Fruit and fruit juice were the most frequently consumed and the most liked snack items. Taste was the most important in choosing a snack item closely followed by health/nutrition. Snack-related knowledge level was relatively high and the participants obtained their nutrition knowledge through mass media (30.4%) and family/friends (29.0%). Snack-related nutrition knowledge level and snack consumption behaviors showed positive relationships in various areas such as choosing more nutritious snack items and checking nutrition labels. Although this study was limited by its cross-sectional study design, these positive relationships suggest that better nutrition knowledge could result in better behaviors. Results of this study indicated that factual nutritional knowledge has been well transmitted to students. Therefore, future nutrition education on snacking could focus more on providing problem-solving and operational knowledge.

The purpose of this study was to examine the sensory processing of adults with intellectual disabilities by Adolescent/Adult Sensory Profile(AASP). AASP was executed for 98 adults with intellectual disabilities residing in nursing home. The score of sensory processing ability expressed the conditions of being 'Less Than Most People' and 'Much Less Than Most People' in the all sensory processing areas of Low Registration, Sensory Sensitivity, Sensory Seeking, Sensory Avoiding. There was not significant difference in the sex. The score of sensory processing ability between teenagers(11 years to 17 years) and adult(above 18 years), teenagers statistically showed lower scores in the three sensory processing areas of Low Registration, Sensory Seeking, and Sensory Sensitivity. In addition, there was significant difference in the sensory processing areas of Low Registration and Sensory Avoiding according to the disability grading. In the future research, it is suggested to examine the sensory processing within residual setting and it need a study comparing sensory processing skills according to the disability grading by increasing subjects.

Stroke is the second most significant disease leading to death in Korea. The conventional therapeutic approach is mainly based on physical training, however, it usually provides the limited degree of recovery of the normal brain function. The electric stimulation therapy is a novel and candidate approach with high potential for stroke recovery. The feasibility was validated by preliminary rat experiments in which the motor function was recovered up to 80% of the normal performance level. It is thought to improve the neural plasticity of the nerve tissues around the diseased area in the stroked brain. However, there are not so much research achievements in the electric stimulation for stroke recovery as for the Parkinson's disease or Epilepsy. This study aims at the developments of a wireless variable pulse generator using ZigBee communication for future implantation into human brain. ZigBee is widely used in wireless personal area network (WPAN) and home network applications due to its low power consumption and simplicity. The developed wireless pulse generator controlled by ZigBee can generate various electric stimulations without any distortion. The electric stimulation includes monophasic and biphasic pulse with the variation of shape parameters, which can affect the level of recovery. The developed system can be used for the telerehabilitation of stroke patient by remote control of brain stimulation via ZigBee and internet. Furthermore, the ZigBee connection used in this study provides the potential neural signal transmission method for the Brain-Machine Interface (BMI).

Due to poor linguistic communication skills of sucklings and infants, crying mostly is only means of communication to express their body conditions and desires. We, therefore, developed an infant auscultation system which detects which part of the body has a pathological problem, by analysing infant's crying sound patterns. Specifically, in this paper, we accomplished an auscultation system for congenital heart diseases detection by performing pitch, intensity and spectrum analysis of the crying sounds between the normal infants group and the congenital heart diseases group. With this system, we can diagnose congenital heart diseases of infants with poor communication capacity, and, in the near future, can build a home care diagnosis system based on crying sound analysis technologies through additional experiments on medical data.

Recently, the character image processing technology using portable device camera image at home and abroad are actively conducted, but Practical use are lower rate because of accuracy and time-consuming process problems. In this paper, we propose the license plate recognition method based on geometric information from portable device camera image. In the extracted license plate region we recognize characters using the chain code and the Thickness information through the cumulative projected edge after performing the pre-processing work considering the angle difference, the contrast enhancement and the low resolution from portable device camera image. The proposed algorithm is effective and accurate recognition by light and reducing the processing time. And, the results from the character recognition success rate was 95%. In the future, we will research about license plate recognition algorithm using long distance image or added motion blur image.

There are a variety of methods to model game results and many methods exist for the case of paired comparison data. Among them, the Bradley-Terry model is the most widely used to derive a latent preference scale from paired comparison data. It has been applied in a variety of fields in psychology and related disciplines. We applied this model to the data of Korean Baseball League. It shows that the loglinear Bradley-Terry model of defensive rate and save is optimal in terms of AIC. Also some categorical characteristics, such as east team and west team, existence of golden glove winning players, team(s) with seasonal pitching leader, and team(s) with home advantage, influenced the game result significantly. As a result, the suggested models can be further utilized to predict future game results.

Magneto-rheological elastomer (MR elastomer) is a smart material, because it has mechanical properties that change under a magnetic field. An MR elastomer changes its stiffness characteristics when the inner particles (iron particles) align along the direction of a magnetic field. There has been much research to make use of this characteristic to control vibration issues in various mechanical systems, such as for mounting systems in the automotive field, home appliances, etc. Furthermore, the friction and wear properties of MR elastomer have been studied, as these relate to the durability of the material needed to meet engineering requirements. Rolling friction (or rolling resistance) is one of these friction properties, but has not yet been studied in the context of MR elastomers. In this study, an MR elastomer is fabricated in the shape of a hollow cylinder to evaluate the rolling friction characteristic under a magnetic field. The test apparatus is setup and a strain gauge is used to calculate the rolling resistance under test conditions. Permanent magnets are used to supply the magnetic field during tests. The load and rolling speed conditions are also considered for the tests. The test results show that rolling friction characteristic has a different trend under different magnetic field, load, and rolling speed conditions. It is assumed that the stiffness change of an MR elastomer under a magnetic field has an effect on the rolling friction characteristic of the MR elastomer. For the future work, the rolling friction characteristics of MR elastomers will be controlled by adjusting the strength of the magnetic field using electromagnets.

The world of today faces a radical change, a new revolution, by the spread of the Internet. It is used not only for advertising but also for the exclusive rights in the field of information and communication, in add to the way of developing everyday our lives with world news, home-shopping, on-line education and so on. Actually, since the Internet Domain's Name(IDN) is unique over the world, the individual and the companies which provide information through the Internet have a keen competition to make a good IDN to memorize and organize all available information provided them. As a result, there are an increasing number of the cases where one company files suit against another for the validity of it's IDN so the policy to arbitrate and solute the cases is required. This paper is going to introduce the structure and the system of management for IDN. It will also discuss the efficient management of IDN, various case analysis of the dispute restraint and solutions, and the movement of improving the management procedure of IDN in WIPO. So we suggest to examine common disputes among IDN uses and solution methods for future problem at EC times. Therefore we have to establish the dispute solution system. Here are the two methods : one is that to establish a dispute solution organization. This organization which can conduct the new dispute solution procedure differs from the existing legislation system. The other is that to establish a dispute solution procedure i.e. the various dispute solution procedure for efficient dispute solution : council, inspection, mediation and arbitration. This procedure is conducted on-line due to features of the IDN disputes, also along with the current legislation system and the International dispute solution procedure. Because there is possibility the IDN disputes usually are connected with other countries. As there is no specific disputes solution procedure so far, we have to wait while development occurs that also striving to be coherent with and between the domestic and International solution procedure by helping to establish the International dispute solution procedure.
