Objectives: In Japan, there are many disasters such as earthquakes and tsunamis, and because of the high temperature and humid climate, health education for food poisoning may be particularly important. In addition, sexual problems caused by precociousness of adolescents, smoking and drinking are already serious socially important problems, and addiction problems are also emerging. Methods: Various publications from Japanese governments, interest groups such as government officers, health center workers, and people from health educators. For the information of Korean health education conditions, a current health educator and people from middle and high schools. Results: In 2012, based on the "Investigation Report on the Mind Care of Children in Emergency Disasters" from the Ministry of Education, Culture, Sports, Science and Technology, the Post-traumatic stress disorder (PTSD) situation of children in East Japan affected areas was discovered, and health education became important. In 2014, the "School Health and Safety Act Enforcement Rule" was amended, and health checkups are emphasized as part of school health. Conclusions: School health education in Japan differs from other health care systems in many ways with the system of Korea in the context of non-existence of official health education curriculum. Therefore, the purpose of this study is to develope how the curriculum of school health education in Korea.

Recently, increased caffeine intake has led to an increase in caffeine addiction and withdrawal symptoms. Coffee is surreptitiously consumed in as an additive to milk and caramel. There are few studies on how coffee affects the health of modern people. The purpose of this study is to determine the efficacy and side effects of coffee by awareness of coffee consumption patterns among college students, who are the principal consumers. A survey was conducted from May 11 to 17, 2015 and 302 questionnaires were analyzed. The respondents were 140 men (46.4%) and 162 women (53.6%). In terms of coffee additives, 151 (50.0%) respondents chose 'americano' and 111 (36.8%) 'variation'. The frequency of coffee intake and sleep time for college students was negatively correlated, with the correlation coefficient of -0.145 and significance probability of 0.019. The group that was 'positively' aware of the principal ingredients of coffee had a higher level of academic training than those with 'negative' awareness (p=0.000). Women recognized a larger number of side effects than men: 1.99 and 1.36, respectively, on average (p=0.001). 'Time for consumption' had statistically significant effects on the side effects of coffee consumption: consumption before/after lunch, before/after supper and before going to bed led to 0.4 times (p=0.048) and 0.3 times (p=0.023) more side effects, respectively, than consuming coffee after getting up and before/ after breakfast. Excessive caffeine intake through coffee led to limited sleep time and poorer learning concentration. The guidelines for proper coffee consumption should be created to help students consume coffee properly so that it will not affect sleep, learning concentration or adversely affect health.

Recently, as education on the use of smart devices increases, there are many side effects such as dependence on smart devices, addiction, and decline of learning effects. This study analyzed the structural relationship between stress and stress coping to understand why dependence on smart devices occurs. Structural equation modeling using Amos was performed to verify the hypothesis. First, it was found that the higher the perceived stress of university students, the higher the stress coping. Second, the higher the active coping, the lower the dependence on smart devices, and the higher the passive coping, the higher the dependence. Third, it was found that there was a difference in the structural relationship according to mindfulness.

Purpose: The purpose of this study was to assess influences of psychological factors on sleep disturbances in young adults through the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Methods: Two hundred and ninety nine college students in Gyeonggi-do completed the MMPI-2 and a questionnaire related to sleep disturbances and collected data were analyzed by logistic regression. Results: The odds of tooth grinding increased significantly with the increase of T-score of hysteria (Hy) scale. The increase of T-score of hypomania (Ma) and social introversion (Si) scale significantly contributed to the risk of insomnia. The occurrence of insomnia increased significantly as T-score of somatic complaints (RC1) and psychoticism (PSYC) scale increased. The odds of tooth grinding increased significantly as T-score of anxiety (ANX) and family problems (FAM) scale increased. The occurrence of insomnia decreased significantly with the increase of T-score of type A behavior (TPA) scale. The increase of T-score of dominance (Do) scale significantly contributed to the risk of tooth clenching. The odds of tooth grinding decreased significantly as T-score of MacAndrew alcoholism-revised (MAC-R) scale increased, whereas it increased significantly as T-score of addiction potential scale (APS) increased. No scale of MMPI-2 significantly affected the occurrence of snoring. Conclusions: T-scores of Hy, ANX, FAM, Do, MAC-R, and APS scales on MMPI-2 affected the risk of bruxism. T-scores of Ma, Si, RC1, PSYC, and TPA scales on MMPI-2 influenced the occurrence of insomnia. The psychometric instrument such as MMPI-2 is helpful in understanding and managing bruxism and insomnia.

With the development of Information Technology in recent years, the image has been an important means to store or express information. Generally, during the process of acquiring and storing images, the images can be corrupted by noise of which typical types are Impulse(Impulse Noise) and AWGN(Addiction White Gaussian Noise). Impulse noise shows irregularly in black and white over the length and breadth of the image by sharp and sudden disturbance of the image signal. In the Impulse noise environment, SM(Standard Median) filter would be used because of its good noise removal performance and simple algorithm. However, when SM filter removes noise, it also produces error at the edge of image and causes whole image quality deterioration. In this paper, we propose a method based on modified nonlinear filter operation scheme which enhances the features of noise removal and detail image preservation when restoring image in Impulse noise environment. And, we compared it with existing methods and the performances through simulation.

Former times Information Technology generally has only depended on text or sound, while nowadays information is being moved through a variety of image media. Cell phone, TV and computer have been major elements of modem society as mediators using image signal. Therefore, image signal processing also has been treated importantly and done actively. The processing has been developed in many fields of digital image processing technologies as image data compression, recognition, restoration, etc. Noises are inevitably generated by using the signals during the processing, and typical types of the noise are Impulse(salt & pepper) and AWGN(Addiction White Gaussian Noise). To reduce the noise, various kinds of filters have been developed, and according to each noise, it is being used different filter each. However, the noise is not generated by one signal but by a complex. In this paper, I suggested an image filter to remove the complex noise, and compared with existing filters' methods for verification.

While the development of digital media has positive aspects of knowledge enlargement and a new communication channel, it also demonstrates a lot of unexpected defects, such as personal isolation, addiction, obsession or Attention Deficit Hyperactivity. Thus, the author considers it is urgent to develop the contents specifically designed for children in this new digital environment and would like to propose the combined Children's device and contents using the new concept of Mixed Reality. The Mixed Reality that mixes real world and virtual world provides the opportunity that can experience the new concept of play education by using touchable interface of children's real life toy cars together with the virtual world in the smart phones. This Mixed Reality that is extended from sole senses will lead the children to develop the concentration, sense of reality and imagination and also to experience the enlarged play and education concept.
