  • Currently, the global atmosphere around the world is altering at a very rapid pace. Among those changes, some are beneficial, but most of the changes are lead to destruction to our planet. The area of environmental science is a significant resource for learning more about these changes. Due to the urbanization, the human population is increasing, natural resources becoming very limited. To solve the limited resources issues, recycling is absolutely an alternative source for the new demands and limitations. Recycling education is very important to raise awareness among students and their communities about the need for recycling and what materials are recyclable locally. In this paper, we reported the role of sustainability science and technology and the impact of recycling research education in the middle schools, both in developing countries and Asian countries and also we included the brief data of global recycling of waste.

  • Formation of a steep plasma density gradient in the middle-latitude ionosphere during geomagnetic storms and the latitudinal migration of its location depending on the storm phase are suggested to be associated with the ionospheric signature of the plasmapause. We test this idea by using the satellite and ground observation data during the 11 April 2001 storm. The locations of the steep plasma density gradient identified by TOPEX/Poseidon (2001 LT) and DMSP (1800 and 2130 LT) satellites coincide with the ionospheric footprints of the plasmapause identified by the IMAGE satellite. This observation may support the dependence of the middle-latitude plasma density gradient location on the plasmapause motion, but does not explain why the steep density gradient whose morphology is largely different from the morphology of the middle-latitude ionization trough during quiet period is formed in association with the plasmapause. The ionospheric disturbances in the total electron content (TEC) maps shows that the steep TEC gradient is formed at the boundary of the positive ionospheric storm in low-middle latitudes and the negative ionospheric storm in middle-high latitudes. We interpret that the thermospheric neutral composition disturbance in the dayside is confined within the middle-high latitude ionospheric convection zone. The neutral composition latitudes and, therefore, the locations of the steep plasma density gradient coincide with the footprints of the plasmapause. The TEC maps show that the appearance of the steep plasma density gradient in the pre-midnight sector during the recovery phase is related to the co-rotation of the gradient that is created during the main phase.

  • Implantable middle ear hearing devices (IMEHDs) have been widely studied as an alternative hearing aids to solve the problems of conventional hearing aids. Vibration transducer of middle ear hearing aids is a key component because vibration characteristics of transducer is directly involved performance of hearing aids. So, the study about middle ear hearing aids concentrate on the transducers. A floating mass type transducer is most efficient. In this paper, we suggest a lumped mechanical model of electromagnetic floating mass transducer implanted on human middle ear. The proposed model enables analysis of the vibration characteristics of a floating mass transducer and prediction of the variation after implant on ossicle that offers a simple and easy to analyze. The parameters was drawn based on the components and the structures of transducer. The Lumped mechanical model was converted by the electrical-mechanical equivalent model, and simulated using PSpice. So, we investigated vibration characteristics of transducer influenced it's components. And we predict vibration characteristics of stapes footplate due to implanted transducer's vibration using combining model of transducer and human ear. To prove the feasibility of the suggested model, we fabricated a differential floating mass transducer (DFMT) as one of floating mass transducers and performed experiments using the human temporal bones.

  • The purpose of this study was to investigate a motivation system about science learning and interest in science among elementary, middle & high school students and analyze on the their relations. For this, the questionnaires on interest in science that developed by Kind et al., (2007) were selected and translated. After that, second-grade 80 students, fourth-grade 87 students, sixth-grade 107 students, eighth-grade 123 students and eleventh-grade 128 students were required to accomplish a questionnaire on behavioral inhibition system/behavioral activation system about science learning (SL-BIS/BAS), interest in science. Based on these materials, SL-BIS/BAS by student's variables and relations of between the system to interest in science have been analyzed. The result of this study shows the followings. First, the sensitivity about SL-BIS was no significant difference in School levels. But sensitivity about SL-BAS and interest in science in elementary and high school was higher than it in middle school. Second, there were low negative correlation with SL-BIS and interest in science, and relatively high positive correlation with SL-BAS and interest in science. Through the results of this study, relations of motivation to related variables, and the motivation by student's variables are identified. These results would be helpful for teachers to understand the difference about motivation by students' variables and to make a plan for the appropriate strategies for learners.

  • Purpose: This study was to investigate middle school students' stress levels and the relation between their stress factors and self-esteem. Methods: Data were collected from 316 students, and analyzed using SPSS 11.5 for Windows. Results: Students satisfied with their school life were more likely to have less stress from 'study', 'school life' and 'family', and those satisfied with their relationship with the teacher had less stress from 'teacher', 'recreation' and 'school life'. Higher self-esteem was observed in those from a family of high economic state, those highly satisfied with school life, and those with good relationship with the teacher. The higher the self-esteem was, the lower stress was. Conclusion: It is necessary to provide more supportive environment in school, and to find out ways to reduce students' stress by enhancing self-esteem. In addition, students and their teachers need to be encouraged to build a warm relationship based on trust.

  • 본 연구에서는 2009개정 교육과정의 중학교 과학교과서에 포함된 탐구 활동이 기존 과학교육에서 강조되어왔던 탐구 기능과 구체적 학생 활동이 강조되는 NGSS의 8가지 과학 실천 측면에서 상호 분석되었을 때 어떤 특성을 나타내는지 생명과학 단원을 중심으로 분석하였다. 분석 결과 학년 구분 없이 탐구 기능에서는 '추리', 관찰', '분류' 순으로 많이 치중되었고, 과학 실천에서는 '자료 분석하고 해석하기'와 '설명구성하고 문제해결 고안하기'에 치우쳐 있었다. 이를 통해 중학교 교과서 내 생명과학 탐구 활동이 탐구 기능뿐만 아니라 과학 실천 요소에서도 다양성이 부족하며 제시하는 활동의 목표가 한정적이라는 것을 보여주었다. 또한 과학탐구 기능과 과학 실천 요소 각 상호 매칭작업을 통해 탐구 기능 중심에서 과학 실천으로의 이행 시 내용 관련성을 검토하고 교과서의 탐구 활동에서 보이는 결과와 비교 분석한 결과 사전 매칭분석에 비해 교과서 내 탐구 활동의 결과가 대체적으로 기초탐구-자료해석/기초탐구-설명고안에 치우쳐 있어서 단조롭게 매칭 되었다. 이는 교과서에 제시된 활동내용의 다양성이 부족함을 보여주는 결과라고 할 수 있다. 본 연구에서는 2009개정 교육과정의 교과서 분석을 통해 단순하고 다양성이 부족한 탐구 활동에서 벗어나 2015개정 교육과정을 구현해나가는 과정에 다양한 과학 실천 요소를 포함시키도록 하는 노력이 절실하게 요구됨을 제언한다.

  • Purpose: This study aims to investigate the effects of a peer gatekeeper training program on existential spiritual well-being, interpersonal relationship with friends, and suicide probability for middle school students. Methods: The participants were fifty students who were at a vocational middle school in D city from october 13, 2012 to november 10, 2012. To test the effects of the peer gatekeeper training program, the participants were divided into two groups in the way of matching distribution, an experimental group(24) and a control group(26). Data were analyzed by Chi-square test, t-test, and Fisher exact probability test using the SPSS/WIN 12.0 program. Results: After attending the peer gatekeeper training program, significant differences between the experimental group and the control group were found in existential spiritual well-being(t=2.80, p=.007) and interpersonal relationship with friends scores(t=2.67, p=.010). However, there was no statistically significant difference in suicide probability between the two groups. Conclusion: The results indicate that the peer gatekeeper training program enhance existential spiritual well-being and interpersonal relationship with friends of middle school students. Therefore, this program could be a good strategy that teachers and community mental health nurses can use for suicide prevention of middle school students.

  • From the onset of puberty or during its progress, eating and health behaviors are important in establishing optimum growth and healthy fitness in middle school students. This study investigated the dietary and health behavior of first grade middle school students(male 260, female 255) selected from 3 middle schools in Suwon. Results were analyzed using the statistical program(SAS ver. 8.1). Usual dietary habits were scored by the Likert scale of 5 points and obtained the mean and standard deviation. Obtaining significant gender difference, chi-square and student t-test were also done. Daily breakfast intake was 70% of all students but some of them ate alone(27.3%). The amount of food intake was slightly less(34.8%) but sufficient food for dinner(53.2%). The purpose of each meal was solving hunger(57.4%). However, they want to change their current eating habits because of an unbalanced diet. Usual dietary habits were similar in gender, but 'apply nutrition knowledge' and 'consider food combination' were better in female students (p<0.01), 'regular meals' were higher in males(p<0.01). With respect to health behavior, the subjects went for daily walks for less than an hour(39.9%) and got 7-8 hours of sleep per day(33.8%). The amount of sleep was sufficient(22.6%) in males but in insufficient (33.8%) in female students(p<0.01). Weight control efforts for reducing(female 27.5% male 20.8%) and for increasing(male 10.6%) differed according to gender(p<0.01). As the result of the above analyses, the direction of nutrition education would be oriented to the nutrition knowledge and food combination applying to the diets of male students and regular meals for females. And also sleep dissatisfaction needs to be altered with taking care weight control trials.
