Scoliosis is defined as a condition in which the spine curves more than 10 degrees in frontal plane. However, it is complicated because it involves transverse and sagittal components as well as the frontal plane. Curvature can progress to growing children and cause serious problems. Treatments of Scoliosis, including observation, are casting, braces, physical therapy, exercise, and surgery. The goal of scoliosis management is to achieve minimal asymmetry by maintaining low angle values. However, it is difficult for adolescents to receive continuous treatment due to study and lack of time. We report cases of scoliosis that have experienced improvement of Cobb's angle through spinal thermal massage management at home.

The CAI has not been developed with the non-structural form of interactive courseware under classroom network. This study suggests the direction of enhancement for students' achievement through interaction between learner and learner. and teacher and learner applied the effective multi-presentation and 4he introduction of the concept of chatting client/server to class with the use of multimedia package. For the continuous development of courseware and the effectiveness of keeping and repairing materials. this study consists of development of the teaching materials by Powerpoint which is one of the multimedia package presentation tools, and teaching method through discussion by chatting client/server under the classroom network. This new CAI showed the possibility of the open education through discussion and the enhancement of learners' effective achievement in the result of the data got from the classrooms of elementary, middle and high schools.

This study examined the factors affecting the underweight of Korean adolescents using data from Korea youth risk behavior web-based survey, which are national health statistics. This is a second data analysis study using the 13th Korea youth risk behavior web-based survey. The subjects were 48,242 adolescents who range from the first-year middle school students to the third-year high school students. The measurement variables were classified into demographic, physical activity, dietary, and mental health characteristics. The collected data were analyzed by logistic regression analysis. The factors affecting the underweight of Korean adolescents were sex, school type, academic performance, economic level, physical activities, weight control efforts, ramen intake, confectionary intake, stress, and subjective sleep fulfillment rate. Based on the results of this study, we need to search for the measures to help underweight adolescents recover their proper weight.

The purpose of this study was to analyze the smart phone usage experience structure for college students. The phenomenology approach was used by conducting 4 times in-depth interviews with the 7 college students age between 20~23. Collected Data was analyzed by Giorgi's phenomenological method. There were 4 general structure descriptions and 28 themes. General structure descriptions were 'Dependence on smart phone', 'Phenomenon of smart phone usage', 'Results of smart phone usage' and 'Relationship between stress and smart phone'. Themes consisted of 'Ambivalence', 'Positive feelings for smart phones', 'Separation anxiety', 'Negative feelings for smart phones'. 'Dependent feelings for smart phones', 'A sense of unity with smart phones', 'Helpful for my life', 'Deeply involved with my life', 'Useful tool in my life', 'Study, communication, relaxation and health care', 'Maintain personal relationship', 'The most important thing in my life', 'Shallow relationship stress', 'Interference with personal relationship', 'Forming a negative relationship', 'Invasion of privacy', 'Forming a Incorrect relationship', 'Unwanted participation', 'No effort to improve relationship', 'Poor concentration', 'Interference with academic study', 'Study assistance', 'Limited help for study in depth', 'Shelter from the stress', 'Amplification of the stress', 'Obsessive focus', 'Feel separation for the reality' and 'Waste of time'. Smart phone usage make college students dependent on smart phones and had negative influence on both personal relationship and academic results. Usage of smart phone also amplified stress. Therefore we need fundamental principles on usage of smart phone and propose to build cultural etiquette that provides reasonable way to use smartphone.

The purpose of this study was to develop understanding-oriented materials based on backward course design model and analyze their effects on 'biology and environment' unit of elementary school science. Backward Design starts from a specification of learning outcomes and decisions on methodology and syllabus are developed from the learning outcomes. This method has a strength maintaining consistency between educational contents-evaluation-learning activities and also promoting student's authentic understanding. The 78 students 6th graders participated in this experiments. Data was collected using project activities, the science academic emotion scale and academic achievement. The collected data was analyzed by t-test and ANCOVA analysis using the SPSS 23 statistical program. The following major conclusions were drawn on the basis of data analysis. First, the experimental group showed a relatively accurate understanding of the contents of science but they could not produce creative output in two project activities. Second, the interaction effect of the instruction based on backward curriculum design and science academic emotion was not significant statistically. Third, the experimental group showed a significant improvement in the academic achievement of 'biology and environment' unit.

The purpose of this study was to identify the correlations between disease related factors and disturbance of daily living in patients with fibromyalgia. A descriptive survey study design was used. Data were collected from 45 out patients diagnosed of fibromyalgia according to the conditions by American College of Rheumatology in I-city. The mean score of tender points were 15.00, fatigue was 8.67, quality of sleep was 12.94 and depression was 23.70. They have struggled with fibromyalgia for 6 years on an average. Among patients, 42.2% had to discontinue their job/learning due to their disease, and experienced a disturbance of daily living for 41.79 days during last 3 months. There were significant positive correlations between disturbance of daily living and tender points, depression, between fatigue and depression, quality of sleep, between quality of sleep and depression. As a result, fibromyalgia patients suffered from various disease related factors and disturbance of daily living. Therefore, it can be suggested that the consideration of these related factors is important to develope intervention program for the better qualified life of the patients.

In this Paper, we Propose an efficient web-based video learning evaluation system that is tailored to individual student's characteristics through the use of user profile-based information filtering. As a means of giving video-based questions, keyframes are extracted based on the location, size, and color information, and question-making intervals are extracted by means of differences in gray-level histograms as well as time windows. In addition, through a combination of the category-based system and the keyword-based system, questions for examination are given in order to ensure efficient evaluation. Therefore, students can enhance school achievement by making up for weak areas while continuing to identify their areas of interest.

This paper proposes an efficient remote video evaluation system that is matched well with personalized characteristics of students using information filtering based on user profile. For making a question in forms of video, a key frame extraction method based on coordinate, size and color information is proposed. And Question-mating intervals are extracted using gray-level histogram difference and time window. Also, question-making method that combined category-based system with keyword-based system is used for efficient evaluation. Therefore, students can enhance their study achievement through both supplementing their inferior area and preserving their interest area.
