The purpose of this study is to investigate discrepant Earth Science terms in high school curriculums and to explore the alternative to those terms. In this study, we defined discrepant terms as different terms which had the same meaning in Earth Science textbooks. Discrepant terms were compared with terms in references and precedent studies, and the preference by 284 of teachers and students was investigated. The results of this study are as follows: A number of discrepant terms were found in references as well as high school textbooks. Participants preferred terms that are more understandable, were learned previously, and were correct to loanword orthography. As for the cases of discrepant terms caused by different notation of proper nouns or different references and background knowledge, the alternative could be explored by the rule of loanword orthography or the journal publications. In conclusion, confusion may be reduced by utilizing common terms that are both based on authorized theory and easy to convey the meaning. 본 연구의 목적은 고등학교 교육과정에서 사용되고 있는 지구과학 불일치 용어를 조사하고 그 대안을 탐색하는데 있다. 고등학교 지구과학 교과서에서 같은 의미를 지니면서 다른 용어를 사용하는 경우 이를 불일치 용어로 정의하였다. 불일치 용어를 참고문헌과 선행 연구의 용어와 비교한 후, 284명의 교사와 학생을 대상으로 선호도를 조사하였다. 연구 결과 불일치 용어는 고등학교 교과서는 물론 참고문헌에서도 다수 조사되었다. 선호도 조사 결과 의미가 쉽게전달될 수 있는 용어, 이전에 학습한 용어, 외래어 표기법에 맞는 용어에 대한 선호도가 높았다. 그리고 고유명의 표기가 다르거나 서로 다른 문헌과 배경 지식에 기반하고 있는 불일치 용어는 외래어 표기법과 학회 발간물에 근거하여 대안을 모색할 수 있다. 따라서 공인된 이론에 근거하고 의미 전달이 쉬운 지구과학 용어를 공유하여 사용함으로써 혼란을 해소할 수 있을 것이다.

본 연구에서는 달의 위상 변화에 대한 과학적 모형 구성 수업에서 나타나는 영재 학생들의 모형 생성 및 발달 과정의 특징과 학생과 교사의 활동이 이 과정에 미치는 영향에 대해 알아 보고자 하였다. 이를 위해 과학영재 학생을 대상으로 과학적 모형 구성 수업을 실시하였다. 수업 전체 및 모둠별 활동을 영상 촬영, 음성 녹음하였으며 선택한 모둠에 대한 면담을 실시 하고 학생들의 활동지를 분석 자료로 활용하여 모둠별 · 개인별 학생들의 모형 생성 및 발달 과정을 재구성하였으며, 학생들의 활동 양상과 교사의 역할이 여기에 미치는 영향을 도출하 였다. 모둠 내에서의 토론이 모둠의 모형 생성 및 발달과정에 기여하며, 표적 모형과 초기모 형의 유사성 정도에 따라 개인 모형의 발달 과정이 달라졌다. 모둠활동에 적극적으로 참여하 는 학생이 많을수록 초기 모형은 다양해지고 최종 모형도 더욱 정교하게 나타났으며, 교사는 모형의 생성 및 발달과정에 큰 영향을 미치는 것으로 나타났다. This study try to analyze feature of model creation and model developing process for gifted students and the activity of students and teachers affected those processes in scientific model constructing class for phase change of moon. For this, I teach scientific model constructing class for science gifted students. I shoot video and record the voice for whole class and each group activity, have a face-to-face talk for selected group members, analyze the paper of activities. I reconstruct model creation and model developing process for each groups and each students, draw a influence that activity aspects of the students and role of the teacher affected modelling process based on those data. After analyzing, I find that discussion in the group contribute model creation and model developing process and developing process of each model changed according to the similarity between target model and first model. The more the students actively participate group activities, the more first model is diversified and final model is more elaborated. Also, the teacher influence model creation and developing process.

The purpose of this study was to provide the baseline data for tourist attraction as a comparison and analysis of two regions which are located near each other and brings tourists with similar local food. The results of the analysis show that the visiting demand or expense demand between the two regions is different, and show that the tourists`` consumption behavior are different depending on the variables. Above this, as a result of correlation analysis between demand and demographic characteristics, we can know that age, marriage, and income are in correlation with demand.

The purpose of this study is to understand the influence of servicescape, which is physical environment, among various elements of theme park. In other words, this study tried to grasp the relationship between servicescape and customer satisfaction, word-ofmouth and revisit. Factor analysis revealed seven factors. The effect of servicescape factors on customer satisfaction differed according to the main factor and the ancillary factors of theme park visitors. It has a high impact on direct elements such as space utilization and comfort, but convenience and accessibility partsare not considered. Customer satisfaction has a statistically significant effect on the word of mouth and revisit, which means that the high satisfaction level of the theme park visitors is that they share experience with others and consider revisit to confirm their experiences. Therefore, the results of this study will be useful in enhancing customer satisfaction and improving revisits through management of servicescape factors.

N/A Backgound/Aims: It has become clear that Helicobacter pylori(H. pylori) is the major etiologic agent of active chronic gastritis and that it plays an important role in the pathogenesis of duodenal ulcer. Although H. pylori is not generally regarded as an invasive organism, there is an increasing recognition that it can be occasionally observed within cells and that infection may result in inflarnmation due to transport of H. pylori products into the gastric rnucosal tissue. But it is not clear at present whether intracellular invasion occurs in certain or all patients. The aims of this study were to assess the usefulness of DNA in situ hybridization in the detection of H. pylori in the gastric tissue and to observe the pathobiological distribution of H. pylori DNA in the gastric tissue. Methods: Rapid urease test(CLO test), hetnatoxylin-eosin stain, Warthin-Starry silver stain, polymerase chain reaction(PCR), and DNA in situ hybridization were performed with endoscopic biopsy specimens from the gastric antrum in the 27 patients with upper gastrointestinal symptoms including 11 patients with non-ulcer dyspepsia, 10 patients with duodenal ulcer, 2 patients with gastric ulcer, 2 patients with gastric and duodenal ulcer, and 2 patients with gastric cancer. Results: The positive rates of H, pylori infection in 27 patients were 59.3% in CLO test, 59.3% in Warthin-Starry silver stain, 66.7% in PCR, 70.47o in DNA in situ hybridization. Out of 27 patients, 15 patients revealed a11 positive results in all the tests, 8 patients revealed all negative results in a11 the tests, 1 patient revealed positive resu)ts in the tests except CLO test, 1 patient revealed positive results in the tests except Warthin-Starry silver stain, l patient revealed positive results only in the PCR and DNA in situ hybridization, and 1 patient revealed positive results only in DNA in situ hybridization. The grade of H. pylori infection in Warthin-Starry silver stain had a positive correlation with the grade of active gastritis in hematoxylin-eosin stain(p0.01). The grade of H. pylori infection in Warthin-Starry silver stain had a positive correlation with the grade of DNA in situ hybridizalion(p0.01). In DNA in situ hybridization, H. pylori DNA was seen in the mucus layer overlaying the epithe- lium in all of the patients who revealed positive results, and occasionally inside the epithelial cell in 6 patients and the lamina propria of the gastric tissue in 2 patients. The grade of H. pylori infection in Warthin-Starry silver stain was not statistically different between the patients with and without H. pylori inside the gastric tissue(P>0.05). The grade of DNA in situ hybridi- zation was also not statistically different between the patients with and without H. pylori inside the gastric tissue(PO.OS). Conclusions: DNA in situ hybridization was an useful metbod in tbe detection of H. pylori in the gastric tissue and H. pylori was occasionally observed inside the epithelial cell and the lamina propria of the gastric tissue as well as in mucus layer.
