This paper presents an implementation result and performance evaluation of pavilion management services that does not only provide real-time status of the pavilion in the forest but also prediction services through machine learning. The developed hardware prototype detects whether the pavilion is occupied using a motion detection sensor and then sends it to a cloud database along with location information, date and time, temperature, and humidity data. The real-time usage status of the collected data is provided to the user's mobile application. The performance evaluation confirms that the average response time from the hardware module to the applications was 1.9 seconds. The accuracy was 99%. In addition, we implemented a pavilion availability prediction service that applied a machine learning-based SVM (Support Vector Model) model to collected data and provided it through mobile and web applications.

To effectively manage lamp facilities on a remote place, it is required to identify a status of the places where the lamp facilities are placed. however, since there is no methods to notify the status of sensors to the central management system based on the non-networked sensor environments, it is difficult to manage the lamp facilities remotely. In this paper, we propose the lamp facility management system to acquire the various status informations of lamp facilities using more than two sensors. To get the status remotely, the system exploits a wireless network based on the ZigBee. The benefit of this system is to help the efficient dicision makings of administrators.

This study was conducted with 20 female gymnasts to examine the relationship between eating patterns, diet menstrual function and hematological status. According to the baseline data a nutrition counseling and education program was developed and evaluated improved the nutritional status and health of female gymnasts. Mean body weight at the onset of the study was 42.1$\pm$7.0kg and was reduced to 41.8$\pm$6.1kg after the nutrition counseling and education program. The percent of body fat was significantly reduced from 13.9$\pm$3.7% to 13.1$\pm$3.1%(p<0.01) skinfold thickness of subscapular and thighs was reduced significantly(p<0.01, p<0.05) Mean daily intake levels of energy, protein calcium iron thiamin riboflavin and niacin were significantly elevated after the nutrition counseling and education program but were lower than the Recommenced Dietary Allowances. For the nutrition knowledge and food habits, the posttest mean scores showed a significant increase. The hematological status(hematocrit, serum ferritin) and the early follicle level of estradiol were elevated to a mild degree although it was not significant,. The follicular stimulating hormone level was elevated significantly(p<0.01) Gymnastica has been one of the sports implicated by the medical profession as having probable detrimental effects. The implications of such training to childs growth and maturation have yet to be determined . Most female athletes, however, experience poor nutritional status and delayed puberty The priorities were to prepared a more effective nutrition program and education material status and delayed puberty. The priorities were prepared a more effective nutrition program and educational material for athletes coaches and adminstrators to prepare guidelines for the team physicians and coaches to follow for the physical and physiological examinations of female athletes.

Purpose: This study was conducted to explore the degree of depression, perceived health status, chronic disease and quality of life(QOL) among rural elderly and to determine the factors related to their QOL. Method: The design of this study was a correlational study. The subjects were 423 elderly consisted of 157(37.1%) men and 266(62.9%) women dwelling in a rural area of N City. Data were collected from May to December, 2003 using a structured questionnaire. A stepwise multiple regression analysis was performed to identify the factors related to the QOL. Result: It was found that the mean score of QOL was in total with 2.15 out of 5.00 and women elderly's score was significantly lower than men(t=2.20, p=.028). Perceived health status showed statistically significant positive relationship with QOL(r=.608, p<.05), while depression(r=-.751, p<.01) and chronic illness(r=-.336, p<.01) showed statistically significant negative relationship. Depression was found to have the highest correlation with QOL among the subjects. Depression score explained QOL at the most, accounting for 36.8% of the variability, followed by perceived health(8.2%) and the number of chronic illness(.7%). Other factors related to the QOL were economic status and absence of spouse. Conclusion: In order to increase the QOL of rural elderly, it is necessary to decrease the depression, to increase their perceived health status and to decrease the number of chronic illness. We suggest the implementation of a program not only to promote physical health status and self-care ability but to take care of mental health for the rural elderly.

Objectives : The purpose of this study was to provide some information on down-to-earth oral health policy to improve the systemic health involving oral health and the quality of life in Korean adults. Methods : The third-year data of the 4th National Health and Nutrition Survey in 2009 were analyzed, and $x^2$(Chi-square) test was carried out to see whether there would be any gaps in subjective oral health status according to demographic characteristics, systemic health state, frequency of eating between meals and oral health behavior. In terms of the DMFT index, one-way ANOVA was utilized, and then Scheffe post-hoc analysis was conducted. Besides, multiple regression analysis was made to grasp the relationship of oral health behavior to subjective oral health state and the DMFT index. Results : The demographic characteristics, systemic health status and oral health behavior had a significant relationship to both of subjective oral health status and the DMFT index. As a result of analyzing the relationship of oral health behavior to subjective oral health state and the DMFT index, the subfactors of oral health behavior exerted a significant independent influence on subjective oral health status and the DMFT index. Conclusions : The findings of the study suggest that in order to promote the oral health of adults, preventive measures should be taken, and systematic oral health education should be provided. As there is an increase in the elderly population in Korea, the successful implementation of senior oral health plans and the development of oral health programs geared toward adults are both required.
