  • This study has investigated the way to improve the communication skills emphasized in mathematics education, and analyzed the effects of Communication Oriented Mathematics Lessons on the mathematical disposition and the academic achievements. For this research, two groups of first grade students from D elementary school in Daegu city were selected which had been proved homogeneous in mathematical disposition and academic achievements via a preliminary test. The experimental group was given Communication Oriented Mathematics Lessons (COML) while the control group was given Traditional Classroom-based Instruction (TCI). COML were given along with first grade, first level mathematics for eight weeks, to improve communication skills of the students who were unfamiliar with mathematical communications. The schemes for the education include revising, summarizing, asking questions, and participating. The results of the study were summarized for mathematical disposition and academic achievements. First, COML is effective to evaluate the will to solve problems in the mathematical disposition of the students, and to make it useful for them to live their lives and to learn other subjects. Second, previous studies have shown contrary interpretations on the effects of COML. This study has found that it does not improve the students' scores on the original form of academic achievement test.

  • Purpose: The purpose of this study was to examine the relationship between the toothpaste squeezing methods and the amount of toothpaste that the daycare teachers apply for the children in order to prevent the overuse of fluoride-containing toothpaste among children, and to understand their educational experiences on oral health and their awareness of the right amount of toothpaste used. Methods: The subjects in this study were 87 teachers at 16 different daycare centers in the city of Sokcho, Gangwon Province. They were interviewed to find out whether they had ever received oral health education and whether they were cognizant of the right amount of toothpaste to be used. And a transverse technique and a pea-sized squeezing technique were selected to look for connections between their toothpaste squeezing methods and the amount of toothpaste used by them. Results: 89.7 percent of the daycare teachers investigated taught to preschoolers how to do toothbrushing after they took meals and had a snack. 36.8 percent of the daycare teachers had children squeeze toothpaste on their own. The amount of toothpaste applied by the daycare teachers at a time was 0.58g. When they utilized two other squeezing methods, transverse technique and pea-sized squeezing technique, they used each 0.38 g (p<0.005) and 0.38 g (p=0.405) of toothpaste. Conclusion: To prevent children from being overly exposed to fluoride-containing toothpaste, daycare teachers should learn about the right amount of toothpaste to be used when oral health education is provided, and the transverse technique should be recommended to ensure the use of the proper amount of toothpaste.

  • The requirements for powerful computing capability, high capacity, low latency and low energy consumption of emerging services, pose severe challenges to the fifth-generation (5G) network. As a promising paradigm, mobile edge networks can provide services in proximity to users by deploying computing components and cache at the edge, which can effectively decrease service delay. However, the coexistence of heterogeneous services and the sharing of limited resources lead to the competition between various services for multiple resources. This paper considers two typical heterogeneous services: computing services and content delivery services, in order to properly configure resources, it is crucial to develop an effective offloading and caching strategies. Considering the high energy consumption of 5G base stations, this paper considers the hybrid energy supply model of traditional power grid and green energy. Therefore, it is necessary to design a reasonable association mechanism which can allocate more service load to base stations rich in green energy to improve the utilization of green energy. This paper formed the joint optimization problem of computing offloading, caching and resource allocation for heterogeneous services with the objective of minimizing the on-grid power consumption under the constraints of limited resources and QoS guarantee. Since the joint optimization problem is a mixed integer nonlinear programming problem that is impossible to solve, this paper uses deep reinforcement learning method to learn the optimal strategy through a lot of training. Extensive simulation experiments show that compared with other schemes, the proposed scheme can allocate resources to heterogeneous service according to the green energy distribution which can effectively reduce the traditional energy consumption.

  • Through the use and development of underground spaces, subways have become a representative means of transportation in the city center. Due to the extension of subway lines and the increase in the number of subway users, there is a risk that safety for evacuating human lives in case of fire will not be secured. Therefore, this study tried to identify citizens' perceptions of evacuation facilities through questionnaires and find alternatives. An online survey of 115 subway passengers was conducted to learn about citizens' awareness of subway evacuation facilities. As a result of the survey, awareness of evacuation facilities was high in the order of guidance lights, life-saving devices, emergency lights and portable lights, special evacuation stairs, and evacuation stairs. In addition, the majority of the respondents said they were not well aware of evacuation facilities, and people's indifference was the most common cause. As a solution to the lack of awareness, responses to active advertising and promotion, education and experience activities were the highest.

  • The purpose of this study is to provide basic data for practical and concrete program development, which can give students satisfaction in sex education. To achieve this purpose, an actual status of sex education for high school student and their sexual experience were investigated. And then tried to find out if there is difference of satisfaction in sex education and contents that they want to learn based on having sexual experience or not. For this study, a questionnaire of sexual awareness was conducted on 562 students among first graders and second graders of high school located in Kongju city, from on October 4th, 2004 to on October 15th. But only 550 answer sheets among 562 were analyzed, for 12 answer sheets were not proper enough to apply to this study. The collected data was computerized using SPSS WIN in frequency and percentage for actual condition of sex education and sexual experience and for satisfaction at the result of sex education based on having sexual experience or not. And then the $x^2$-test was verify the difference. The requirement for sex education, based on having sexual experience or not, was analyzed using t-test by computerizing the average and standard deviation. The conclusion of this study are as followings; 1. 93.8% students have ever been taught for sex education by teachers, but nursing teacher among them was the higher percentage than any other teachers. They took courses for sex education in discretion class, and the teaching method was a kind of lecture. 2. After taking sex education, 37.6% students said that it was boring, for they had already known the contents of the courses, and 43.8% students said that they acquired sex knowledge through the Internet and mass media. 3. It was highest percentage that 36.9% students had no agony about sex. The most serious worry was a sexual impulse and the sexual psychology of the opposite sex. To solve these worries, 61.6% students said that they consulted with their friends. 4. It showed that 89.9% male students and 71.6% female students had experiences various lascivious materials, 81.4% male students, 7.2 female students experienced masturbation, 52.7% female student and 44.8% male students experienced kissing or hugging, and 13.7% male students and 9.9% female students experienced sexual intercourse. 5. The satisfaction for sex education based on having sexual experience or not was different. In short, it showed that the students who experienced sexual experiences such as accessing to lascivious materials, kissing, hugging, and sexual intercourse except masturbation thought that sex education was important than the students who didn't experience sexual experiences. On the other hand, the students who didn't experience sexual experiences were more satisfied with the contents and level of sex education than the students who experienced sexual experiences. 6. The requirement for sex education based on having sexual experience or not was also different. The students who experienced sexual experiences wanted to learn an acquaintance with the other sex than the others. On the other hand, the students who didn't experience sexual experience wanted to learn friendship and love. The students who experienced sexual experience except masturbation was more desirable for taking sex education than the other students. In conclusion, it is fully required that sex education should be regular subject in school and teachers who are charge of sex education should be experts in this field, for only expert can teach systematic and adequate sex knowledge to students. In addition, it is also essential to understand contents of sex education which can be satisfactory for students' requirement. So we should develop concrete and practical programs for sex education.

  • Location branding is a very important income making activity, by giving special meanings to a specific location while producing identity and communal value which are based around the understanding of a place's location branding concept methodology. Many other areas, such as marketing, architecture, and city construction, exert an influence creating an impressive brand image. A place brand which shows great recognition to both native people of S. Korea and foreigners creates significant economic effects. There has been research on creating a strategically and detailed place brand image, and the representative research has been carried out by Anholt who surveyed two million people from 50 different countries. However, the investigation, including survey research, required a great deal of effort from the workforce and required significant expense. As a result, there is a need to make more affordable, objective and effective research methods. The purpose of this paper is to find a way to measure the intensity of the image of the brand objective and at a low cost through text mining purposes. The proposed method extracts the keyword and the factors constructing the location brand image from the related web documents. In this way, we can measure the brand image intensity of the specific location. The performance of the proposed methodology was verified through comparison with Anholt's 50 city image consistency index ranking around the world. Four methods are applied to the test. First, RNADOM method artificially ranks the cities included in the experiment. HUMAN method firstly makes a questionnaire and selects 9 volunteers who are well acquainted with brand management and at the same time cities to evaluate. Then they are requested to rank the cities and compared with the Anholt's evaluation results. TM method applies the proposed method to evaluate the cities with all evaluation criteria. TM-LEARN, which is the extended method of TM, selects significant evaluation items from the items in every criterion. Then the method evaluates the cities with all selected evaluation criteria. RMSE is used to as a metric to compare the evaluation results. Experimental results suggested by this paper's methodology are as follows: Firstly, compared to the evaluation method that targets ordinary people, this method appeared to be more accurate. Secondly, compared to the traditional survey method, the time and the cost are much less because in this research we used automated means. Thirdly, this proposed methodology is very timely because it can be evaluated from time to time. Fourthly, compared to Anholt's method which evaluated only for an already specified city, this proposed methodology is applicable to any location. Finally, this proposed methodology has a relatively high objectivity because our research was conducted based on open source data. As a result, our city image evaluation text mining approach has found validity in terms of accuracy, cost-effectiveness, timeliness, scalability, and reliability. The proposed method provides managers with clear guidelines regarding brand management in public and private sectors. As public sectors such as local officers, the proposed method could be used to formulate strategies and enhance the image of their places in an efficient manner. Rather than conducting heavy questionnaires, the local officers could monitor the current place image very shortly a priori, than may make decisions to go over the formal place image test only if the evaluation results from the proposed method are not ordinary no matter what the results indicate opportunity or threat to the place. Moreover, with co-using the morphological analysis, extracting meaningful facets of place brand from text, sentiment analysis and more with the proposed method, marketing strategy planners or civil engineering professionals may obtain deeper and more abundant insights for better place rand images. In the future, a prototype system will be implemented to show the feasibility of the idea proposed in this paper.
