In this study, we designed a device for consecutively observing position, utilizing 3-axises acceleration sensor. This method offer to check his or her wrong position and developed could to help derived a position appliance. And, we developed a Cobb's angle value in three dimensional using 3-axises acceleration sensor. A proposed device with integrated accelerometers, which can detect postural changes in terms of curvature variation of the spine in the sagittal and coronal planes, has been developed with intention to facilitate posture training. The proposed device was evaluated with 3 normal subjects daily activities. We evaluated the performance of our designed device as calculating the correlation coefficients and mean errors between the angle measured by an electro-goniometer and that estimated by a gravity accelerometer and verified the accuracy and sensitivity. The results showed that the angle obtained from the proposed device revealed a linear characteristic at the range of $\pm60^{\circ}$(correlation coefficient 0.99, error range $\pm2^{\circ}$). We demonstrated that our device could detect the changes of the motion in upper trunk accurately. Also, our device showed good potential for treatment of the patients with scoliosis and prevention of the unbalance position during a daily life.

The study examined the effects of fathers' parenting involvement and parenting behaviors on child happiness. A total of 270 elementary school students in 4th, 5th, and 6th grades (139 boys and 131 girls) participated in the study and completed the questionnaires. The collected data were analyzed using descriptive statistics, analyses of variances, correlation coefficients, and multiple regression. Fathers' parenting involvement and parenting behaviors did not differ by gender and grades, but child happiness partially differed in response to those factors. Additionally, child happiness was significantly positively correlated with fathers' parenting involvement and parenting behaviors. Moreover, fathers involvement in leisure activities, daily-life guidance, and study guidance, as well as their being warm receptive and rejective restrictive parenting behaviors were found to be significant variables influencing child happiness. Overall, the results of this study suggest fathers' play important roles in child happiness and that development of an education program for fathers is warranted.

The purpose of this study was to find the effects of parenting behavior, parenting involvement and father-child communicationon on children's multiple intelligence. For this purpose, 182 children selected from three elementary schools and their fathers participated in the study. The findings of this study are as follows : First, there were some significant differences in children's multiple intelligence according to the children's grade, gender, father's educational background and income. Second, there were some significant differences in children's multiple intelligence according to the parenting behavior, warmth acceptance, rejection restriction and permissiveness nonintervention behaviors, and to leisure activity, life guidance, study guidance of parenting involvement and to father-child open communication, problematic communication. Third, It was also found that children's grade, gender, father's educational background, warmth acceptance behavior, permissiveness nonintervention behaviors and open communication, problematic communication were all significant predictors of the children's multiple intelligence. In order to increase the children's multiple intelligence, parents should be warmer and more accepting and have open commnication with their children.

The purpose of this study is to develop and evaluate a parent-child reading interaction program. Based on the importance of the parent-child relationship and the home literacy environment vis-a-vis the extent to which reading is encouraged, and with regard to the existing empirical research in this field, a five-session parent-child reading interaction program has been developed, targeting 18 parents with children enrolled in th lower grades of elementary school. The effectiveness of this program has been evaluated by a pretest and post test and then analyzed by a paired t-test. The findings are as follows: 1) Following the implementation of this program, there were improvements in scores related to the home literacy environment, the encouragement of reading, and the attitude of the child toward reading. 2) In addition, there was an increase in the level of the mother's "rational guidance" parenting while tendencies toward overprotective and hostile parenting traits declined. The importance of the parent-child relationship and home literacy environment concerning reading guidance was discussed.

Last year's Goseong-Sokcho forest fires have highlighted the limitations of extinguishing work for night-time forest fire and the importance of quick identification for information on the spread of forest fire. However, it is not easy to find services that take into account the characteristics of forest fires, as most existing disaster-related mobile applications and research assume various disaster situations rather than just forest fire situations. Therefore, a system that can provide information quickly is needed, taking into account the characteristics of forest fires and the limitations of extinguishing work. In this paper, we propose evacuation route guidance services that bypass areas where fire has already spread, supplement existing methods of extinguishing work, and provide general information on forest fire situations in real time, by putting drones into forest fire situations. It has been implemented to automate image analysis using the Rekognition service of Amazon Web Service (AWS), and the results of fire detection and the T Map API guide the evacuation path. It is expected that the results of this paper will allow efficient and rapid rescue and extinguishing work to be carried out, and further reduce the damage of human life caused by forest fires.

In this study, 45 pre-service mathematics teachers were surveyed about how the perception of knowledge through teaching practicum have changed and how the knowledge learned in college and teaching practicum helped to format teachers' knowledge and analyzed survey's result. Pre-service mathematics teachers felt the knowledge for understanding students were needed the most and considered the experiences from teaching practicum were more useful than the knowledge learned from college classes. However, they had low appreciations on connecting knowledge on learned contents with real-life or other subjects and on necessity of knowledge of using various learning tools or mathematical materials in class. Also, they have answered the knowledges from college classes and teaching practicum were useless in those areas. Especially, they pointed out that guidance teachers during teaching practicum were insufficient in instructing. Therefore, we suggest the following two to improve the teaching ability of pre-service mathematics teachers through teaching practicum. First, college and secondary school cooperating programs such as class-observation and student-mentor system connected with local society should be developed. Second, the special re-training program for guidance teachers of teaching practicum is needed.

The Korean government enacted the National Health Promotion Act in January, 1995 and proclaimed its regulations and rules in September 1995, which became the basis of the national health policy. The health promotion programs consist of education for health, prevention of diseases, improvement of nutrition, and practice of healthy life style as defined in that Act. The Community Health Act was amended in 1995, which included implementing nutrition services in community health centers. The purpose of this report is to summerize the nutrition services conducted in 32 community health centers. the main nutritional activities were as follows : 1) nutritional guidance by counseling and education for pregnant or lactating women, infants, preschool children, and those with chronic diseases, 2) collection, analysis, and interpretation of data collected from the community, on background conditions and target population for the assessment of community needs, 3) evaluation of nutritional status of population in the community 4) nutritional guidance for mass feeding in different institution including schools and welfare institutions. In order to meet the government's expectations and desires, the community health centers have made continuous efforts to put nutritional activities into practice in the community. However, there are constraints, such as relative staff shortages, lack of funds, and information which hampers the nutritional activities.
