In various sensor network applications, such as climate observation organizations, sensor nodes need to collect information from time to time and pass it on to the recipient of information through multiple bounces. According to field tests, this information corresponds to most of the energy use of the sensor hub. Decreasing the measurement of information transmission in sensor networks becomes an important issue.Compression sensing (CS) can reduce the amount of information delivered to the network and reduce traffic load. However, the total number of classification of information delivered using pure CS is still enormous. The hybrid technique for utilizing CS was proposed to diminish the quantity of transmissions in sensor networks.Further the energy productivity is a test task for the sensor nodes. However, in previous studies, a clustering approach using hybrid CS for a sensor network and an explanatory model was used to investigate the relationship between beam size and number of transmissions of hybrid CS technology. It uses efficient data integration techniques for large networks, but leads to clone attacks or attacks. Here, a new algorithm called SBEA (Snowball Endurance Algorithm) was proposed and tested with a bow. Thus, you can extend the battery life of your WSN by running effective copy detection. Often, multiple nodes, called observers, are selected to verify the reliability of the nodes within the network. Personal data from the source centre (e.g. personality and geographical data) is provided to the observer at the optional witness stage. The trust and reputation system is used to find the reliability of data aggregation across the cluster head and cluster nodes. It is also possible to obtain a mechanism to perform sleep and standby procedures to improve the life of the sensor node. The sniffers have been implemented to monitor the energy of the sensor nodes periodically in the sink. The proposed algorithm SBEA (Snowball Endurance Algorithm) is a combination of ERCD protocol and a combined mobility and routing algorithm that can identify the cluster head and adjacent cluster head nodes.This algorithm is used to yield the network life time and the performance of the sensor nodes can be increased.

Objectives: The purpose of this study was to identify the stages of change distributions for nine major health behaviors among poor children in underserved area, and to provide basic information for developing specific objectives and strategies for health education program. Methods: The health behavior data were obtained with a self-administered questionnaire and analysed for 3,081 poor children in 106 local children's centers nationwide. Stages of change classification were based on self-reported responses to five statements. The health behaviors included were balanced diet, safety behavior (helmet and protective device use while riding), regular exercise, smoking, alcohol use, drug use, sleep pattern, weight management and stress management. Results: Poor children were more likely in precontemplation and less frequently in action and maintenance stages for a safety behavior. 33.1% of respondents were precontemplators, 29.9% contemplators, and 6.5% in preparation stage. Only 4.3% and 9.6% were in action and maintenance stages, respectively. Gender differences were apparent. Boys were more likely to be precontemplators for nine health behaviors. Children from the lowest socioeconomic status and disrupted family were more likely to be in precontemplation for weight management and exercise behaviors. Children living with both parents were more likely to be in the action and maintenance stages for nine health behaviors. Stages of change for balanced diet and smoking were significantly related with those for other eight health behaviors. And the stage of exercise adoption was found to be significantly related with those for other seven health behaviors. Conclusion: Safety education must receive high priority in health education program for low income children. Balanced diet smoking cessation and regular exercise could be a possible gateway behavior toward healthier lifestyle practices.

Objectives : The aim of this study was to provide basic background information on stroke by evaluating various etiological factors on the basis that the onset time of cerebral infarction varies according to its cause. Methods : We studied hospitalized patients within 4 weeks after their ictus who were admitted at Kyunghee OMC, Kyungwon OMC, or Donguk Ilsan OMC from [month] $1^{st}$, 2005 to June $30^{th}$, 2007. We compared the general characteristics of acute stroke patients according to onset time. Results : Regardless of the onset time, the distribution of cerebral infarction patterns showed high SVO. The onset time did not show significant difference for average age, height, weight, BMI, waist measurement, hip measurement, or waist/hip ratio between onset during sleep and awakening. Patients whose stroke occurred while awake were more likely to have a past history of HTN, DM, ischemic heart disease, or atrial fibrillation but did not show significant difference according to their onset time. Conclusions : The above results show that the overall tendency of acute stage cerebral infarction patients varies according to their onset time. This study was carried out on the basis of previous findings that cerebral infarctions that occurred during sleep were more likely to have been caused by cerebral thrombosis, and strokes that occurred while awake were more likely to have been caused by cerebral embolism. However, there were no statistically relevant results, so a larger study group is needed to research the tendency of stroke patients.

In order to evaluate menopausal syndrome objectively, examinations were performed as follows: 1) Simplified Menopausal Index (SMI Koyama) and QOL questionnaire (Nagata) were examined subjectively. 2) Urine 17-KS-5 (S Nishikaze), 17-OHCS (OH) were examined objectively. 3) A mobile telemedical device with EKG and KSG was lent to Patients. The subjects were 48 menopausal patients who visited our university hospital as outpatients. According to the results of 5, OH, the subjects were divided into 4 Groups; Group I is high S & high OH, Group ll low S & low OH, Group 111 is low S & high OH, Group tl is high S & low OH. Group IH was the largest (64.6%), Group of was none. The subjects showed significantly lower QOL condition and higher score of SMI. In the QOL, questionnaire items of fixation to physical status (psychogenic reaction), sleep (insomnia), pain(chronic pain) were in common. In SMI, functional vascular symptoms were the largest number. On treatment, Group I was considered to have no need for supplementary agents, but anti-Oketsu agents was prescribed. For Group ll and in some supplementary agents such as red ginseng were prescribed, because they showed low 5. In conclusion, all the groups showed a sign- nificant improvement of QOL and SMI. Group I showed a decrease of OH, Group ll showed an increase of 5, Group In showed an increase of S and SIOH and a decrease of OH. These phenomena were considered prohomeostatic. In QOL, the items of chronic pain, insomnia and appetite were improved. In SMI, chillness, dyspnea, palpitation, pain and fatigability were improved. In mobile tole-medical device, abnormal findings were found in 88.2% of patients. General sdaptation syndrome (Selye, H.) is considered to adjust human life. Menopause is the transit period to exhausted stage in it. So its symptoms vary from person to person. In conclusion, 5 and OH are useful both for classification of menopausal syndrome and for determining treatments according to the classification
