Cupric sulfate powder of average diameter 2㎛ was reacted with hydrogen at the temperature range of 240-350℃ in a fixed bed reactor and concentration of effluent sulfur dioxide was measured. Experimental results showed that sulfur dioxide regeneration efficiency of 93.6% was maximum at 300℃. The reaction of cupric sulfate with hydrogen was able to be interpreted by the shrinking unreacted core model with chemical reaction as rate controlling step. The reaction was found to be first order for the hydrogen concentration and the reaction rate constant was k=0.0165 exp (-2047/RT).

Background : Through many researches, microsatellite is expected to be a good diagnositic and prognostic factor in colorectal cancer, endometrial cancer, gastric cancer, and the others. The prevalence of microsatellite instability (MSI) in gastric carcinoma has reported variously, 13~44%. Purpose : We aimed to determine the prevalence of MSI-high and the relationship between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma of stomach. Material and Methods : We analyzed 106 sporadic intestinal type adenocarcinoma specimens excised from patients who were over thirty-five years old to determine the statue of microsatellite by DNA sequencing. The tissues were formalin-fixed and paraffin embedded. DNA were extracted and amplified by polymerase chain reaction (PCR). MSI was determined using five markers recommended by National Cancer Institute (NCI). Specimens were also studied with five patholical factors-differenciation of tumor cells, depth of invasion, lymph node metastasis, vessel invasion, and perineural invasion- to determine pathological state. Result : The microsatellite statue was determined as MSI-High in 5 cases (4.7%), no MSI-low, and MSS (microsatellite stable) in 101 cases (95.3%). Within the frequency, there was no large gap in the distinction of gender in MSI cases, but in MSS cases, there was three-times more cases in male. MSI cases had moderate-to-poor differenciation and trend to invade toward serosa. All MSI cases showed no perineural invasion. But we could not find any statistical significance between MSI and pathological characteristics of sporadic intestinal type adenocarcinoma. Conclusion : Results suggest that MSI can not make any certain pathological significance in sporadic intestinal type adenocarcinoma. Even though less than 5% of sporadic intestinal type adenocarcinoma patients showed MSI, it can be used as a influential prediagnostic factor of gastric cancer. Further study with large scale of cases will be followed to verify these results.

Myeong-Hee Shin,Eunpyo Lee 한국영어어문교육학회 2012 영어어문교육 Vol.18 No.3

This study examines the importance of learning language and cultural integration in general English class focused on TOEIC reading comprehension. The understanding of cultural learning and learners’ cultural awareness has long been a subject of debate. This study was not only to analyze the improvement of students’ interest and reading comprehension ability of TOEIC through cultural learning, but also to ensure students who learn American culture overcome crosscultural miscommunication and improve their English reading comprehension skills. Pre-post surveys and the pre-post TOEIC tests were used to measure language proficiency and American cultural knowledge to two groups: the experimental and control group. The results from the study were as follows: First, students had better TOEIC scores with improved motivation after understanding American culture relevant to the lessons. Second, reading comprehension skills with regards to TOEIC also improved, compared with the students who were not exposed to American culture due to lack of opportunity.

본 연구의 목적은 서비스러닝을 통한 교실 안의 학습이 지역사회에 실용적으로 전이될 수 있는 자기주도 학습과의 관계를 탐구하는 것이다. 본 연구의 대상은 2019년 9월 1일부터 2019년 12월28일까지 교양 과목 수강 학생을 대상으로 하였다. 본 논문의 연구 문제는 서비스러닝 기반 교양수업과 자기주도 학습과의 관계는 어떠한가? 즉, 서비스러닝기반 교양수업이 자기주도 학습의 하위 요소인 개방성, 자율성, 문제해결력, 자기평가에 어떠한 영향을 미치는가이다. 그렇다면 학습자 개인의 변인은 자기주도 학습 능력에 어떻게 영향을 미칠 수 있는지를 알아보고자했다. 연구결과, 자율성과 문제해결능력 r=.66으로 높은 상관관계를 보여주었고, 개방성과 자기평가(r=.60) 자율성과 자기평가(r=.55)가 통계적으로 유의미한 상관관계의 결과를 가져왔다. 서비스러닝에 있어서의 학습자 자율성은 서비스러닝 활동의 학습 촉진 및 협력과 유의미한 상관관계를 보였다(<SUP>**</SUP>p<.01) 이 연구의 결과를 통해, 향후 학생들은 자기가 학습한 내용을 심화하여 지역사회기관 봉사를 통해 실천하고 경험하며 학교에서의 배움이 강의실에 머물러 있지 않고 사회로 환원이 가능한 개방성, 자율성, 봉사의 실천을 통해 실질적 세계에서 부딪칠 수 있는 문제해결 그리고 성찰을 통한 자기평가가 가능하다. 또한 학습자들은 사회 구성원으로서의 책임감과 민주시민으로서의 자존감을 고취 시킬 수 있었다. This study examined the effect service learning combined with self-directed study had on transferring skills from the university classroom to their practical application in local community centers. The subjects of this study were students who took service learning classes from September 1, 2019 to December 28, 2019. The research question in this paper is "What is the relationship between service learning-based general classes and self-directed learning?". That is, how do service learning-based general classes affect sub-elements of self-directed learning? We then tried to determine how the variables of individual learners can affect self-directed learning ability. The results showed that autonomy and problem solving were the greatest at r=.66. Openness and self-assessment (r=.60), autonomy and self-assessment (r=.55) had significant correlation. Learner autonomy had a significant correlation with facilitation and collaboration of service learning (<SUP>**</SUP>p<.01). According to this result of the study, it is possible for learners to deepen what they have learned at school and to practice and gain experience through community service. Further, practical problem solving and self-assessment through reflection are possible. Learners were able to inspire responsibility as members of society and increase self-esteem as democratic citizens.
