The purpose was to examine the association between healthy weight and physical activity, screen time, and nutrition based on community characteristics in mountainous region. The sample consisted 1,620 middle school students in West Virginia, the United States. A logistic regression and in-depth interview were conducted. Moderate to Vigorous Physical Activity and consumption of vegetables and fruits were associated with healthy weight, while screen time was not associated with healthy weight. Regional limitations may cause that students had too much exposure to screen time and should be minimized by using school facilities during weekend. In particular, schools need to provide regular health seminars and parents education to overcome regional isolation and slow internet speed. Therefore, it suggests the cooperation between schools and parents may be required in order for students to be healthy in mountainous region.

In this study, an attempt was made to prepare an effective human rights sensitivity education plan for nursing students. This study was before and after a non-equal control group that identified human rights sensitivity and patient rights awareness. As a result of the study, the human rights sensitivity of the subjects averaged 40.22 out of 90 points. The effect on human rights sensitivity through case-based human rights sensitivity education showed that students who received training to improve case-based human rights sensitivity improved human rights sensitivity and patient rights awareness than those who did not(t=2.765,p=.006, t=-5.768,p=.000). As a result of this study, it is considered that the foundation of the curriculum to improve the human rights sensitivity of nursing students should be prepared. We propose a later study on the relationship between clinical practice and human rights sensitivity.

The speed of change on information technology is very fast, so it demands a continuous competency development in IT human resource management. If the competency development for IT personnel can not keep up with the change of Technology, IT personnel cannot accomplish their IT job under new IT environment. For this reason, many companies have tried to manage IT organization separately and IT job system on the technology basis. Although the training of IT is different from that of other field in feature, few studies about IT human resources system have been conduced. Therefore this study focuses on the training system of IT personnel and suggests the framework for institutionalizing the operation policy and the individual process through a case study methodology. This paper chose one company as a case study which implemented the training system of IT personnel recently, and the proposed framework based on the literature review from this study applied to a company. The study shows that IT job system needs to be reasonably established, job descriptions should be appropriate to IT job, and there exist two training paths according to two career path - Specialist and Generalist. For the purpose of high performance in IT division, the training manager should understand IT job system, the people who need training, and keep an eye on the IT trends and new IT skills.

This article made overtures of the relationship between interactive mathematics texts nd the prototype design of computer application with Computer Algebra System Math. Engine, linking together in the school mathematics. School teachers and researchers would try to construct mathematical materials with computers in educating students in the middle and high school grades. As the individual users come to manage hyper-media materials, so they meet with the problem of 'Who does control?'A mass user would be concerned with interactive mathematics materials directly or off-line at realtime and manipulate the process of problem-solving symbolically with MathView/sup 11)/ and ON-Math/sup 12)/. Discussion was made in developing the factor in the domestic situation and reaching out their hands for it. In conclusion, a user may reform the information of math-curriculum limitedly.

Many researchers in the 21st century has found that robot education is effective to develop the learners' creativity and problem-solving ability. However, the robot education can only be applied to the students whose computer skills are high. Also it can be taught in the well-prepared computer classroom. Students have to learn machine language to control their robots, and robots are controlled by different types of software. Therefore this study has constructed command-based programming blocks to do a robot programming without computers. It also presents a prototype of the programming process and a technological method to combine the command and the programming blocks. We used the blocks which are similar with something in flow chart: to support intuition, and to help students transfer what they learned. And types of blocks and details are described for the Robot Programing Education. Combination of command blocks is made by RS-485 connection method and, it is designed to intercommunicate with connected blocks. It also presents a prototypes: of the programming process using designed command blocks, and of the possibility of Unplugged Robot Education System.

This paper propose to use a new educational programming language, Scratch, to help students' programming study. For this purpose, a course has been developed which consists of (1) strategies to motivate students and (2) Creative Problem Solving (CPS) teaching model to improve their problem solving abilities. We experimented the course with sixth-grade elementary students for 4 weeks and we could observe that the Scratch programming learning helps motivating students and improving their problem solving abilities. Based on this observation, we believe that Scratch programming can be an alternative for current programming education in elementary schools.

Women engineering education programs in the United States, Europe and Australia were analyzed. From 1970s, these countries focused on the low representation of women in engineering, and carried out extensive research and programs. Numerous studies identified the causes of low representation as low interests in mathematics and science during K-12 years, classroom environments which treat women differently (often referred as chilly climate), and the masculine culture in engineering. Comprehensive approaches were taken in the development of the programs: the programs utilized the schools and universities as well as various local institutes, and the programs were designed not only for female students from elementary to graduate levels, but also for parents, teachers, professors, and school administrators. In order to adopt these programs in Korea, the problems that Korean female engineering students are facing in the education environment must be investigated first. Then, unified efforts to change the educational system, environments and culture are needed by all in engineering fields, along with nation-wide policies and funding.

The purpose of this research is to confirm that how the support type of the assistant teacher changes the students' creativity and self-efficacy in the Robot Education, particularly Robot Edu-Camp. The study objects are 72 elementary students for 8 groups; each group has 9 students, and 4 groups of them have the assistant teachers and others are supported by giving some feedbacks for their questions or some information if they need. The assumption of this study sets up as in the following; there are no differences for the students' creativity and self-efficacy between the supporting of the assistant teachers with making robots and programing together and the giving feedbacks and information if students need. To verify this assumption, we use the nonequivalent control group in the pretest-posttest designs. The result is as in the following. There's no meaningful differences of the students' creativity by the support type of the assistant teachers. But in the self-efficacy, the groups which are giving feedbacks and information if they need have more higher level of achievement than others. The result shows that if the assistant teachers help the students directly, the students' levels of the self-direction, and control are low because they lean on the teachers. This will give you some implications to the follow-up studies about the support type of the assistant teachers in the Robot Education.

This study is to search the problems of schoolyard teaching material developed by pre-service earth science teachers and the critical factors affecting material making. The 258 schoolyard teaching materials was collected from 54 pre-service earth science teachers (male: 18, female: 36) major in Earth Science Education in Jeonju, Korea. The schoolyard teaching materials was greatly influenced by making process type of it and the prior knowledge of pre-service earth science teachers. As schoolyard preference exploratory type rely on their prior knowledge to develop the schoolyard teaching materials, they made use of the limited concepts like fault in material making. But the concept preference exploratory type made use of concepts not accessible to majority of pre-service earth science teachers because they selected a concept from the earth science textbook first of all. The pre-service earth science teachers having wrong prior knowledge selected inappropriate resources, as well as fell into the error of concept connecting. The pre-service earth science teachers having right prior knowledge partly considered only shape of resources, but had a disregard for formation process of it in material making. Accordingly, we need to reflect richly Geological Field Trip and Solid Earth Science to curriculum for earth science teacher education. And we have to educate pre-service earth science teachers to create holistic concept on the geological subject matter knowledge, field based teaching and learning strategy, material making process.
