Recently, Peer-to-Peer (P2P) live streaming assisted by the cloud computing has attracted considerable attention to improve the reliability of the P2P such as the resilience to peer churn and the shortage of upload capacity. The cost of cloud-assistance is comprised of the number of requests issued to the cloud and the amount of data fetched from the cloud. In this paper, we propose three techniques to reduce the cost of such a cloud-assistance.More concretely, in the proposed method, 1) each peer which lost its parent in the overlay can find a new parent by referring to the information registered in the cloud, 2) several peers which proactively fetch chunks from the cloud are dynamically invested, and 3) the number of requests issued to the cloud is reduced by allowing peers to fetch a collection of chunks using a single request. The performance of the proposed method is evaluated by simulation. The simulation results indicate that it reduces the cost of conventional scheme by 46% while guaranteeing the quality of live streaming service.

The purpose of this study was to investigate the situation of occurrence of disease and accidence of child care center. The subjects of this study were 17 public district child care centers, but only one center kept their health diary. Therefore, it became finally the only subject for this study. The data were collected through the analysis it's health diary and case reports for emergency. The collected data were analyzed by the number of cases, age and sex, types of case, and the emergency case were analyzed by age, background, types of accidents and follow up. The number of cases of disease and accident in 2002 were 572. In sexual difference, boys more have accident than girls. The teachers and the outsiders also frequently use the health care service. Smallpox and epidemic conjunctivitis were spreaded during winter and summer. In causes of accidents, 'accident by other child' were 98%. In emergency cases, 1 pierced wound, 1 dislocation, 2 dental emergencies, 4 eyeball contusion and bleedings and 2 burns were occurred. all the cases of emergency were performed follow up education. On the basis of above data, there will be needed to intensify health and safety subjects in curriculum for the teacher of child care, and health and safety education for child. Each child care centers must have health care manager and the network for emergency. To enhance the quality of child care service, government have to offer financial and systematical support.

In order to detection of the intestinal parasites, fecal samples were taken from broiler (n=262), laying hen(n=244), parent stock(n=207) and native stock(n=287) in Chonbuk province. The prevalence and identification of intestinal parasites were determined by the fecal examination using the floatation and /or sedimentation methods and microscopical examination, respectively. The results were obtained as follows : 1. The detection rate of parasite-eggs from 4 flocks(total=1,000) was 65.7%. 2. In the breed and type of breeding, infection rate of parasite-eggs was detected 84.0％ as native stock (floor breeding, 241 chicken), 79.7％ as parent stock (floor breeding, 165 chickens), 73.3% as broiler(floor breeding, 192 chicken) and 24.2% as laying hen(cage breeding, 59 chicken), in order. 3. In the concern of mixed infection such as single, double and triple, the rate was 55.1%, 8.7% and 1.9%, respectively. 4. Ten kinds of infective eggs were isolated from 657 fecal sample of 4 flock. They were classified 51.l% as Eimeria spp., 12.7% as Ascaridia galli, 5.1% as Capillaria spp., 4.1% as Strongyloides avium, 2.3% as Heterakis gallinarum, 0.5% as Hymenolepis spp., 0.3% as Railleina spp. and 0.2% as Syngamus spp., Trichostrongilus spp., or Choanoteania spp., single or in combination.

This study intended to provide information which gives a way for students and their parents to be satisfied with student costume purchase by showing differences between their satisfactions and repurchasing intention according to school uniform purchase type. Total 280 questionnaires were distributed to the first year students at a private middle school in Seoul and 133 of copurchase cases and 120 individual purchase cases were collected and analyzed. The comparing results between parent satisfaction and repurchasing intention were summarized as follows. First, parent satisfaction of individual purchase and of co-purchase had been evaluated. As a result of the analysis of satisfaction by the five factors, individual parent buyers had higher satisfaction in brand, quality, design, and service except price. The largest different factor between both customers was quality satisfaction. Secondly, the individual buyers showed higher repurchasing intention than co-purchasing buyers. This result meant that individual purchasing group showed higher satisfaction. Lastly, when the relationship between satisfaction and repurchasing intention of each buyer group was examined, the level of satisfaction was positively associated with the repurchase intention of co-purchase.

In this paper, we propose a distributed parent peer selection method to construct an efficient peer-to-peer(P2P) network topology by considering the capacity of a peer and the hop distance from a data source to the peer. To achieve this goal, we propose a method to combine the two performance metrics to calculate the probability that a peer becomes a parent peer. Using the probability, we propose a method to select a parent peer stochastically by making use of the state information of the neighboring peers that each peer maintains. Through simulation studies, we show that the proposed method drives high capacity peers to support more children peers and makes the diameter of the P2P network shorter than the other methods.

We development the service that teacher and parent can control the smart phone of student in school and home, the name is I_smart_keeper. The service is composed of server system, teacher's application, parent's application and student's application. The control of student's phone in school is operated by school timetable and GPS(Global Positioning System) in smart phone. The student's phone is operating one of six policy. The six policy is 'emergency call only', 'specific application only', 'call only', 'call and text only', 'all allowed' and 'all lock'. The teacher can change the current policy with his or her phone, That is a the temporary policy can be applied on a day. In school hours, teacher is able to instruct student using application appropriate to the teaching. If student is leaving school early and located outside school, the service do free the student's phone by GPS of her or his phone. We show the Smart Health Indicator (SHI)that analyse the pattern of student's phone habit and SHI will guide a desirable student's phone habit. In home, parent can control child's phone. The service will help the risk reduction of a robbery case due to keeping student's phone by teacher in class. Currently one elementary school's all student use I_smart_keeper and three elementary school is testing to some class. The teacher's impression was very good and they usually use I_smart_keeper for class in positive light. Survey results for students with higher satisfaction.
