필자들은 제37회 교육자료전시회(1997)와 제38회 교육자료전시회(1998)에 작품을 출품하였다. 이들 교육자료전시회에 참가하게 된 동기는 다음과 같다. 입문기 아동의 수학교육은 학습내용에 대한 흥미를 가지도록 해야 하며 구체적인 조작활동을 통하여 수량에 대한 기초적인 개념과 원리, 그리고 법칙을 바르게 이해시켜 논리적 사고력을 기르도록 해야 한다. 그러나 대부분의 아동들을 목표수준에서 보면 만족스럽지 못하고, 시간이 지날수록 학습결손아가 늘고 있는 현실이다. 특히 오름길 학습지를 해결할 때는 우수한 아동에게도 조작활동을 시켜보면 뜻밖에 조작 활동을 제대로 못하고 당황하는 경우를 흔히 볼 수 있다. 이것은 개념 형성과 개인간의 차에 관심을 둔 지도가 이루어지지 않은 상태에서, 자기능력과 수준에 맞는 학습을 하지 못하고 다음 단계로 넘어가기 때문이라 판단하였다. 이에 필자들은 교과서에 예시한 활동이나 그림 자료들을 실제로 관찰하고 조작해 볼 수 있도록 구체적인 자료로 대체하여, 수학에서 요구하는 학습지도 원리에 적합하도록 하였다. 또 교실 수업에서 야기되는 개인차에 대한 학습지도상의 문제점을 해결하는 한편, 급우간 인간관계에 바탕을 둔 소그룹 협동 학습을 위한 자료로 수와 가감산의 원리를 쉽게 체득 시킬 수 있도록 하였다.

The purpose of this study was to investigate the relationship between physical activity participation habits, physical fitness level, and academic performance among the Reserve Military Training Corps (ROTC). Participants in the current study were 71 ROTCs from J University. Physical activity participation was investigated using the Global Physical Activity Questionnaire (GPAQ), and the level of physical fitness was measured by health-related physical fitness evaluation. For academic performance, university grade data (GPA) was approved by the head of the relevant school district, and the data were collected with the consent of the participants, and each data was analyzed. The correlation between physical activity participation habits, physical fitness level, and GPA was analyzed, and GPA by physical fitness level were compared. This study found that there was no statistically significant correlation between physical activity participation and academic performance. Otherwise, there was a statistically significant correlation between major subjects and total physical fitness score, cardiorespiratory fitness, muscular endurance, flexibility, and body composition. By the level of physical fitness, the ROTCs in the high-physical fitness group showed statistically significantly higher academic performance than the ROTCs in the low-physical fitness group. In addition, low level of physical fitness ROTC group was lower than the other. In conclusion, ROTCs with a high physical fitness level had a positive effect on improving learning ability compared to those who did not. By recommending an autonomous but systematic exercise training program, it is suggested to improve the physical strength of ROTCs and to cultivate excellent future military officers.

In this paper, care-giving teachers' recognition of their activities to increase infants and children's rights respect were studied, and teachers' required actions to enhance infants and children's rights respect were analogized. To conduct this survey, focus group interviews were done for 2 groups' care-giving teachers: each group was constructed with 6 teachers. In care-giving teachers' daily work, respected or non-respected various cases on their infants and children's rights respect were intensively reviewed. From this result, total 12 sub categories and detail 40 items were extracted as care-giving teachers' required activities to activate infants and children's rights respect. The aforementioned teachers' activities must be conducted as top priority at their care-giving activities for infants and children's rights respect.

This study analyzed the reporting activities of journalists who covered MERS-CoV in 2015. Twenty-one reporters were interviewed to investigate their differences in reporting. They were categorized into four small groups based on their specialism and professionalism. Some specialist reporters answered that they acknowledged the first MERS patient through an external source. A few special reporters contacted foreign experts for further information and one of them answered that she read academic articles on MERS to verify governmental announcements. Specialist reporter groups and the other groups showed difference when they were asked the situation they felt something was going wrong in governmental communication: Many specialist reporters pointed out the outbreak of a patient from out of the monitoring people, but many general reporters emphasized the policy of the government not to reveal the name of hospitals that the outbreaks happened.

The purpose of this convergence study is to understand the knowledge of cervical cancer and its prevention of cervical cancer in unmarried women. 216 women were collected through self-report questionnaires and analyzed by SPSS program. In result, human papilomavirus vaccination was performed in 33.9%, pap test was performed in 7.9%. The human papilomavirus vaccination and pap test group were 6.7% and human papilomavirus vaccination or pap test group were 28.5%. According to the cervical cancer prevention activities, several differences were detected in the family history of cervical cancer, subjective norms of cervical cancer prevention, perceived behavioral control, and behavioral intention. Therefore, it is important to increase susceptibility of the prevention of cervical cancer in unmarried women, and it is important for the health professionals to perform the most meaningful support system preventing cervical cancer in unmarried women. In addition, various policies should be actively promoted that unmarried women participate in the prevention of cervical cancer actively.

Achieving a certain degree of objectivity is one of main assessment priniciples to meet and self-assessment has been under-used as a formal instrument for assessing students' achievement due to lack of objectivity. Now, this research attempted to look into how students perceived self-assessment and how they engaged in the assessment process. Self-assessments and in-depth interviews with students were collected as main data sources. The results of data analysis are as follows. First, a student' perceptions of self-assessment have been observed to change over a course of a semester. Furthermore, changes in perceptions might have led students to get ownership of their learning. Conclusively, this research proposes that the research of self-assessment be accommodated into the socio-cultural context to demonstrate its desirable influence on students' learning.

The purpose of this study was to investigate how the argumentations were affected by the students' characteristics in the small groups. The level of self-concept and science related attitude were examined to the eleventh grade high school students in Daejeon city, and the twelve students were participated for this study. The participants were divided into homogeneous groups and heterogeneous groups. The argumentations under the condition of the interpretations about the experimental results in each small group were recorded by VCR. The recorded data were transcribed, then argumentation levels from transcripts in each small group were analyzed through Mitchell's parameters of argumentation. The results of this study were that the group which had higher level of both self-concept and science related attitudes achieved higher level of argumentation. Therefore, it is necessary for teachers to induce students to ask questions and present activities appropriately in order for those who have low self concept and science related attitudes to participate in argumentation.

Any errors that are generated in the channels and networks distort the video quality and are propagated in both the spatial and temporal domains. In particular, header errors ran result in serious visual degradation of the output video encoding/decoding schemes that can make an error resilient compressed bit-stream in error prone environments, such as mobile networks. In this paper, we proposes an header error resilience method that consider the activity of macroblock in video bitstream syntex. The extract of header error repaetedly embeds the header parameters into the least significant bits(LSB) of the quantized DCT coefficients prior to VLC. Experimental results show that the proposed error resilience method restores good image quality despite the detected error on header parameters.

This study was to analyze the inquiry characteristics of preservice teachers as they classify trilobites. For the study, 70 preservice teachers attending teacher training university participated. The classification tasks used in the study were 9 photos of trilobite fossils. The preservice teachers' inquiry activity was to classify the evolutionary processes of trilobites after observing trilobite fossils by group and then to construct a phylogenetic tree. The results of the study are as follows. First, preservice teachers observed the external features of the trilobites and constructed systematic classification results based on their observed contents. Second, preservice teachers classified trilobites using various classification criteria. Third, the phylogenetic tree of preservice teachers and the phylogenetic tree of scientists were very similar. The preservice teachers constructed a sphylogenetic tree based on the observation and inference of the change from a simple form to a complex form, which is a general evolution process of the trilobite fossil claimed by scientists. These results suggest that group-based inquiry activities with sufficient time are very effective and that the experience of inquiry activities is very important for preservice teachers.
