For this study, in order to understand the perception level of foot reflex therapy and clarify its related factors among customers using foot care service centers, a survey was conducted based on structured self-administered questionnaire with 181 users of three foot care service centers located in Daejeon between September 1 and October 30, 2011. The results showed that the average score in perception level of the subjects regarding foot reflex therapy was $32.19{\pm}5.32$(Score scale of the 11 items 0-44) and people with higher level of education had a significantly higher perception level(p=0.020).The perception level based on attitude and practice of foot reflex therapy was significantly higher in the group who do it "to heal illness"(p=0.034); and who "had illness" at the time when they started the therapy (p=0.030); when they used the foot massage for a longer period (p=0.000); and those in the group who would "recommend it"(p=0.004). In multiple regression analysis, among the factors that affect perception level of foot reflex massage, reason for using foot reflex therapy, health state when starting foot reflex massage, period of using foot reflex massage, and experience of recommendation to other people were selected as significant variables, with the explanatory power of 26.1%. The results suggest that perception level of foot care service users regarding foot reflex therapy are more correlated to variables that explain their attitude and practice than general characteristic variables.

This study was conducted to identify the relationship between knowledge, attitude, and compliance regarding infection preventive behaviors among long-term care hospital staff during a Middle East Respiratory Syndrome (MERS) epidemic. The subjects were 211 staff members of a long-term care hospital in J province evaluated using a structured survey. Data were collected between June 15 and July 15, 2015 and analyzed using SPSS/WIN 24.0 based on an independent t-test, ANOVA, and Welch test, while post-hoc tests were conducted using the Scheffe test and the Grames-Hawell test. The MERS knowledge score of the staff at the long-term care hospital was high for nurses and nurse aids, who had experienced infection management when they received influenza vaccine in the previous year and were provided with easy access to hand sanitizers. Attitude towards MERS was more positive for nurses than nurse aids and caregivers. The degree of execution of infection preventive behaviors in terms of daily activity was high when influenza shots were received in the prior year; in terms of caring for patients, it was high when influenza shots were received in the previous year and they had easy access to hand sanitizers. The relationship between knowledge, attitude, and infection preventive behavior regarding MERS was such that high knowledge and positive attitude led to a higher degree of execution of infection preventive behavior. Therefore, during periods of high prevalence of newly infectious diseases such as MERS, it is important for the long-term care hospitals to conduct infection management education including the characteristics of the MERS disease, its transmission, and its prevention to enhance knowledge regarding MERS and induce positive change in attitude to improve the level of infection preventive behaviors.

In this paper, we present a method to extract the text lines in poorly structured documents. The text lines may have different orientations, considerably curved shapes, and there are possibly a few wide inter-word gaps in a text line. Those text lines can be found in posters, blocks of addresses, artistic documents. Our method based on the traditional perceptual grouping but we develop novel solutions to overcome the problems of insufficient seed points and vaned orientations un a single line. In this paper, we assume that text lines contained tone connected components, in which each connected components is a set of black pixels within a letter, or some touched letters. In our scheme, the connected components closer than an iteratively incremented threshold will make together a chain. Elongate chains are identified as the seed chains of lines. Then the seed chains are extended to the left and the right regarding the local orientations. The local orientations will be reevaluated at each side of the chains when it is extended. By this process, all text lines are finally constructed. The proposed method is good for extraction of the considerably curved text lines from logos and slogans in our experiment; 98% and 94% for the straight-line extraction and the curved-line extraction, respectively.

Routing protocol in ad hoc mobile networking has been an active research area in recent years. However, the environments of ad hoc network tend to have vulnerable points from attacks, because ad hoc mobile network is a kind of wireless network without centralized authentication or fixed network infrastructure such as base stations. Also, existing routing protocols that are effective in a wired network become inapplicable in ad hoc mobile networks. To address these issues, several secure routing protocols have been proposed: SAODV and SRPTES. Even though our protocols are intensified security of networks than existing protocols, they can not deal fluidly with frequent changing of wireless environment. Moreover, demerits in energy efficiency are detected because they concentrated only safety routing. In this paper, we propose an energy efficient secure routing protocol for various ad hoc mobile environment. First of all, we provide that the nodes distribute security information to reliable nodes for secure routing. The nodes constitute tree-structured with around nodes for token escrow, this action will protect invasion of malicious node through hiding security information. Next, we propose multi-path routing based security level for protection from dropping attack of malicious node, then networks will prevent data from unexpected packet loss. As a result, this algorithm enhances packet delivery ratio in network environment which has some malicious nodes, and a life time of entire network is extended through consuming energy evenly.

The purpose of this study is to provide the necessary data for the effective performance of school nurse's work by comparing with the recognition and expectation on school nurse's work by the students and their teachers in school settings. The sample of this study was consisted of the 441 students and 535 teachers in Suwon. The data were collected by means of a structured questionnaire from 24th, Sept, to 29th, Sept. 1990. The collected data were analyzed utilizing SAS/PC program for percentage, frequency, mean, standard deviation and chisquare test. The major findings of this study were as follows: 1. The result of analysis in recognition on school nurse's work. There is no statistically significant difference 'depending on teachers' school level, sex, age and career with school nurse(P>0.05). The students show significant difference on their school level and sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest recognition and school environment management has the lowest recognition. 2. The result of analysis in expectation on school nurse's work. There is statistically significant difference depending on teachers' and students' school level: the order of expectation is elementary, middle, and high school(P<0.05). In the result of comparison with students' and teachers' expectation in the same school level, there is significant difference only in elementary school(P<0.05). However, there is no statistically significant difference depending on teachers' sex, age, career with school nurse and students' sex(P>0.05). Also, in the areas of school nurse's work, school clinic management has the highest expectation and school environment management has the lowest expectation. Synthesizing the result of the study, we can have the conclusion like following. First, students' recognition on school nurse's work is lower than teachers' because most of school nurse's work is performed through their homeroom teachers or other teachers. That can be the limitation for students to recognize school nurse's work. So, there must be a chance of regular meeting between school nurse and students to perform school nurse's work effectively. For this. we must change our educational system and make school nurse charge regular lesson. Second, in each area of school nurse's work, both students' and teachers' recognition and expectation about the area of school environment management has much lower score than the other areas. This indirectly shows the school nurse don't do the work of the area actively. So, school nurses must make an effort to do the work of the area actively. And we must enforce the education of this area in education for new school nurses or re-education for school nurses.
