The purpose of this research was to investigate the relationship between the change of beginning teachers` beliefs about a lesson and that of teaching practice and argument-based inquiry using science writing. Participants were three science teachers (A, B, and C) from different middle schools. Classroom observation and interview data were collected and transcribed for analysis. A Summary Writing test was also administered to examine whether there was an improvement in students` learning. The results indicated that the interaction between the teachers and their students developed, which is concluded as an improvement in the teaching practice. Teacher A and B also reported that teacher-student interaction had improved. Teacher A and C came to understand that argumentbased inquiry using science writing classes constituted learner-centered instruction. The result from the Summary Writing Test showed the impact of the changes in teaching practice and in teachers` awareness of students` learning as well as produced meaningfully higher scores than compared groups on the rhetorical structure of all the specific areas in teacher A`s school and on the scientific concept at B and C`s schools.

This study examined the effect of the Collaborative Problem-Solving for Character Competence (CoProC) instruction model within the context of secondary science education. The participants of this study were comprised of 143 Korean students, each of whom was in the 10th grade spread across four class cohorts. These cohorts were further divided into an experimental group (comprised of 73 students from two different classes), which received the CoProC program; and a control group (70 students from two other classes), which did not. In order to assess the effect of CoProC instruction model upon participants’ character competence, we designed and administered a Character Competence Test for participants. The CoProC instruction model consists of 3 fundamental steps: Preparation, Problem-solving, and Evaluation. Key character competence targeted in the CoProC program include caring, collaboration, communication, responsibility, respect, honesty, self-regulation, and the development of positive self-image. Thus, these same qualities were targeted and analyzed in the Character Competence Test, which was administered before and after the CoProC activities. The results show a significant increase in the experimental group’s competency for caring, collaboration, responsibility, respect, and self-regulation when compared to the control group. Based on these results, we have found that CoProC instruction model to be an effective teaching intervention toward cultivating character competence in a secondary science education setting.

Purpose: Acute aerobic exercise has been shown to attenuate brachial blood pressure (BP) reactivity to sympathetic activation, though whether it also attenuates central BP reactivity remains unclear. We tested the hypothesis that an acute bout of aerobic exercise would attenuate central BP reactivity to sympathetic activation. Methods: In a randomized crossover design, 15 healthy adults (23±0 years and 23±1 kg/m2) completed two trials; (1) acute aerobic exercise (30 minutes at 60% of heart rate reserve) and (2) sitting as a time control prior to the cold pressor test (CPT) in a randomized order. During the CPT, a hand was submerged up to the wrist in an iced water bath (4°C) for 3 minutes. Heart rate and brachial and central BP were measured at baseline, during and after the CPT. Results: Heart rate, and brachial and central BPs increased similarly during the CPT in both trials and returned to baseline after CPT (time effect, p< 0.05). However, brachial systolic BP reactivity to the CPT was attenuated in the acute aerobic exercise trial compared to control trial (interaction effect, p< 0.05). In addition, the magnitude of central systolic BP reactivity during the CPT was less increased in the acute aerobic exercise trial (Δ19.8 mmHg) versus in the control trial (Δ24.6 mmHg) (p=0.017). Conclusion: These findings demonstrated that acute aerobic exercise attenuated both brachial and central BP reactivity to the sympathetic activation, suggesting that aerobic exercise may have a favorable effect on central BP reactivity to the sympathetic activation in young adults.

논의-기반 탐구 과학수업에서 역할분담에 따른 고등학생들의 인성 역량 변화 분석

The purpose of this study is to investigate the impact of Argument-Based Inquiry (ABI) strategy on student's character competency. For this study, 51 grade 11 students (two classes) were selected to the role assignment (ABI-R group) and 46 students (two classes) were assigned to the non-role assignment group (ABI group). In the result, the role assignment group (ABI-R group) showed a statistically higher change in character competency than the group without role assignment (ABI group). Particularly, the ABI-R group has significantly higher grade than ABI group in empathy, responsibility, and respect among the sub-factors of character competency. However, in the case of the cooperation factor of character competency, the ABI group showed statistically significant higher grade than ABI-R group. The results of this study showed that Argument-Based Inquiry (ABI) as teaching and learning strategies in science can contribute to the enhancement of human character competency. In addition, we suggest that students should be actively involved in the class through role assignment, but it is necessary to present the class situation so that they can be actively engaged according to the problem situation rather than being fixed in a given role.

Object : The purpose of this study was to measure the natural changes of cognitive function over 6 month and to determine which cognitive tests were valuable for early detection of dementia in community dwelling elderly. Method : Cognitive function were measured in 94 elderly registered at the Public Welfare Center in Gwacheon, the urban community of Kyunggido. After 6 months, same cognitive functions were re-measured in 54 elderly. The measures were Korean version of Mini-Mental State Examination (MMSE-K), Subtests of Korea Version of Memory Assessment Scales (K-MAS), Verbal Fluency Test, Clock Drawing Task, Wechsler Digit Substitution Test and Wechsler Similarity Test. Results : The mean age was 73.61±5.97 year. Most part of the tests were influenced by education, but not by age and sex. Of the MMSE-K subtests, the score of memory registration and memory recall declined after 6 months. The score of delayed recall of K-MAS declined, too. Decreased score was also observed in 'country' of the category verbal fluency test and 'n' of phonemic verbal fluency test, Wechsler digit substitution test and Wechsler similarity test. But, score decline was not statistically significant. Three persons were diagnosed as dementia after 6 months. And, they acquired low scores in above cognitive function tests in first cognitive function tests. Conclusion : Memory registration and memory recall of MMSE-K, delayed recall of K-MAS, verbal fluency test, Wechsler digit substitution test and Wechsler similarity test were sensitive to cognitive decline. The results suggest that cognitive function tests could be applied to detect minimal changes of cognitive function in community dwelling elderly.

BACKGROUND: Recently in Korea, the import of agricultural products is rising due to the increasing amount of trade. Unregistered pesticides, allidochlor, propachlor, propham, cycloate, diallate and pebulate are widely used as pesticides for rice cultivation in foreign countries, while they are not registered in Korea. Therefore, the residue amount of imported agri-foods should be verified using the proper official analytical method for each of them that has not registered in Korea. METHODS AND RESULTS: This work was conducted to apply the official method of Korea Food & Drug Administration (KFDA) for determining multi class pesticide multiresidues in agricultural commodities. Brown rice and orange which have different characteristics as a matrix were selected as representative samples for residue analysis. The recoveries of cycloate, diallate and pebulate by GC/MS in fortified brown rice and orange with levels of 0.04~0.4 mg/kg were ranged from 82.8% to 110.3%. The quantification limits of three pesticides in brown rice and orange were 0.04 mg/kg. CONCLUSION: As a result, this method can surely be used as an official method for routine analysis of unregistered pesticides in Korea for imported agri-food.
