The 7th Science Curriculum of Korea is applied in elementary schools from 2000, and the New Science Curriculum of Japan is applied in schools from 2002. In this study, we made a comparison between the 7th Science Curriculum of Korea and the New Science Curriculum of Japan in relation to Elementary school in aspects of construction, aim, and contents. The major findings of this study are as follows. 1. The New Science Curriculum of Japan presents a specific aim, treatment of content, and process skills according to grade, but the 7th Science Curriculum of Korea does not classify them according to grade. Hence the 7th Science Curriculum of Korea emphasize on the sequence between grades. 2. In aim of Science Curriculum, the 7th Science Curriculum of Korea show more emphasis on the practical application than the New Science Curriculum of Japan. 3. In construction of content, a area of science content is handled with gradual advance in several grades and several areas of content are treated in a grade in the 7th Science Curriculum of Korea. On the contrary, a area of content is treated intensively in a grade in the New Science Curriculum of Japan. Therefore, the 7th Science Curriculum of Korea shows more reflection of connection and hierarchy between grades. 4. The statements of the 7th Science Curriculum of Korea are centering around specific matters and include specific activities, but the New Science Curriculum of Japan focuses on concepts to learn and does not state specific activities.

The purpose of this study is to investigate the possibility of induction and the effect of cognitive conflict through dyadic debate with peer who had different conception about the action and reaction in the middle school. In this study, 108 eighth grade students were participated, who already had learned the action and reaction concept. The students` preconceptions about the action and reaction were examined. And two students who had different conceptions were paired randomly according to students` preconceptions. The students listened to and described idea of their partners`. Then, there was a chance to debate freely each other. The levels of cognitive conflict and conceptual change to the partner`s conception were examined accordingly. In result, first, debating with peer who had different conception raised cognitive conflict in students` mind. This result indicates that the debate with peer is a kind of anomalous situation to students, and cognitive conflict can be raised by debate with peer. The levels of cognitive conflicts were different according to one`s own and partner`s conception. Second, some students changed their conceptions to partners` conceptions through debate with peer. The levels of conceptual change of students were also different according to one`s own and partner`s conception. These results lead to the conclusion that peer dyadic debate could be used to produce cognitive conflict situation in science teaching.

This research is a foundational study for developing a cognitive conflict learning strategy model considering characteristics of physics concepts and students` affective variables. The purpose of this study is to investigate the science teachers` understanding of the cognitive conflict learning strategy and the practice of the learning strategy in science classes. The total of 40 science teachers who had taken the lectures of `science pedagogy` and `science learning and instruction: theory into practice` in graduate school were selected for this study. The participants were asked to answer a questionnaire and participated interviews. Data have been collected by the questionnaire and the interviews. The conclusion can be summarized as follows. First, Most science teachers recognized that the cognitive conflict learning strategy is important and has a good effect on students` conceptual changes when learning science. However, there are many kinds of difficulties in their applying it to classroom context. Among them, to solve the teacher`s factor and the lack of teaching/learning materials, we need to develop not only the science pedagogical curriculum composed of practice and application related to concrete conceptual change learning strategy, but the systems to spread the developed materials. Second, qualitative approach seemed to be necessary to get further developing the cognitive conflict learning strategy model based the characteristics of physics concepts and student`s affective variables.

혈액투석 환자에서 Bioelectrical Impedance Analysis를 활용하여 측정한 과수분량과 근육량 감소와 사망률의 상관관계

목적: 혈액투석 환자에서 체수분 상태는 중요한데 혈액투석 이후의 과수분 상태는 고혈압, 부종, 심혈관계 합병증을 유발할 수 있다. 혈액투석 환자의 근육량 평가 및 체수분 상태를 측정할 수 있는 BIA 검사를 이용하여 혈액투석 환자에서 이환율, 생존율과 관련된 인자를 알아보고자 하였다. 방법: 본 연구는 후향적 연구로 2010년 1월부터 2015년 5월 30일까지 BIA를 측정한 말기 신부전으로 진단받고 투석을 3개월 이상 시행한 환자를 대상으로 하였으며, 2017년 6월 30일까지 추적 관찰하였다. 혈액투석 환자에서 시행하는 기본 혈액 검사와 BIA data (ECW, ICW, TBW, SLM, FFM, SMM 등)를 참조하여 환자의 이환율, 생존율 등을 분석하였다. 결과: 사망군과 생존군에서 SLM, SMM, FFM의 차이는 없었다. 생존군에서 사망군보다 나이, C-반응단백 수치가 낮았고, 혈청 알부민, 부갑상샘호르몬, 인이 높았으며, 총 체액량(TBW) 중 세포외액량(ECW)의 비율은 사망군에서 좀 더 높은 결과를 보였다(0.39 ± 0.01 vs. 0.40 ± 0.01; p < 0.05). 과수분군을 ECW/TBW ratio > 0.4로 정의하였을 때 Kaplan-Meier 생존분석에서 과수분군에서 통계적으로 유의하게 사망률이 높았다. 결론: 혈액투석 환자에서 BIA로 측정한 근육량 감소과 과수분 상태는 환자의 사망률과 이환율과 관련된 중요한 인자로 생각되며, 근육량 감소보다는 과수분 상태가 사망률과 좀 더 밀접한 관련이 있을 것으로 생각된다. Background/Aims: Assessment of fluid status in hemodialysis patents is very important. Overhydration in hemodialysis is associated with generalized edema, cardiovascular complications, and hypertension. The aim of this study was to determine the factors correlated with mortality of hemodialysis patients, assessing body muscle mass and fluid status using bioelectrical impedance analysis (BIA). Methods: This study enrolled 93 patients who underwent hemodialysis between January 2010 and May 2015 at CHA Bundang Medical Center. Medical records of enrollees up to June 2017 were reviewed retrospectively. These included laboratory results (serum albumin, C-reactive protein [CRP], lipid profile, etc.) and BIA data (extracellular water, intracellular water, total body water, soft lean mass, fat free mass, skeletal muscle mass, etc.). Results: Eleven of 93 patients had expired by May 2017. Among the surviving subjects, mean age was younger, CRP levels were lower, albumin levels were higher, and extracellular water/total body water (ECW/TBW) ratios were lower than in the expired patient group. Kaplan-Meier survival analysis revealed that overhydration (ECW/TBW > 0.4) was associated with higher mortality. Conclusions: In hemodialysis patients, overhydration is an important factor in mortality, and BIA could be a reliable modality in its assessment. We suggest that, for hemodialysis patients, overhydration is more of a risk factor for mortality than is muscle wasting. (Korean J Med 2018;93:548-555)

Jaundice is a rare symptom of the paraneoplastic syndrome associated with prostate cancer. We report a case of metastatic prostate cancer that presented as jaundice. There was an absence of biliary obstruction and hepatic metastasis; therefore, the paraneoplastic syndrome was suggested as the etiology of cholestasis. Jaundice improved with the treatment of prostate cancer. In the literature, interleukin-6 has been suggested to be associated with paraneoplastic syndrome. (Korean J Gastroenterol 2021;78:59-64)

In this study, we have investigate the concept of the 5th and 6th grade elementary school students on the pressure of the gas using the network analysis. The instrument was developed for estimating students's understanding of the concepts relating to the origin, direction and some properties of the gas. It consist of 7 items including 2 multiple choice items and 5 two-tier mutiple choice items. We can summarize our results as follows: 1. A large portion of the 5th and 6th grade students appeared to have understood the origin of the pressure of the gas in terms of the weight of the air (5th:83.2%, 6th:58.3%), and a relatively large portion of the 6th grade students also had understood it in terms of the molecular motion comparing with the 5th grade students (5th:26.5%, 6th:41.7%). 2. Both the 5th and 6th grade students appeared to have correct concept on the direction of the pressure of the gas (5th:67.3%, 6th:72.5%), but, relatively large portion of the 5th grade students showed not to have understood it such that the pressure of the gas acted only on the outside of the inflated ball. 3. The 5th grade students seemed to explain the properties of the gas more intuitively than the 6th grade students, who explained the same phenomena with more scientific ideas.
