An investigation into the relationships between faculty members` perception of WBI attributes and environmental support to the adoption of WBI

( Soon Shik Suh ) 한국교육공학회 2001 Educational Technology International Vol.3 No.1

Although Web-based instruction (WBn is believed to have great potential for providing an avenue to change the structure of higher education institutions and the integration of WBI is regarded as natural and inevitable. t here is no guarantee that faculty members would use WBI enough to justify the efforls and the cost of developing it. The intent of this study was to identify the current extent of Web-based instruction (WB!) use among faculty- members of the higher education, and to investigate the relationships between the identified four predictor variables (relative advantage, compatibility, subjective norm, and environmental sup· port) and their current extent of WBI use after initial adoption of WBI. The res ults showed that the percentage of faculty members at the utilization level of WBJ use was more than that of faculty members at the integration leveL In other words, the findings of the study showed that WB] has still been underutilized in teaching and learning in higher education and that there is a dis· crepancy between the actual and the potential extents of WBI integration. Two variables of perceived relative advantage and subjective nonn emerged as being significantly correlated with and as predictors of WBI use. The results of the study generally concurred with Rogers`` diffusion of innovation theory revealing that perceived relative advantage of WBl is a significant predictor of levels of use. This result is also congruent with Theory of Reasoned Action of which su bjective n rm is an important component.

캐즘이론과 정보기술수용모형을 적용한 디지털 교과서 수용 연구

서순식 ( Soon Shik Suh ),윤한기 ( Han Gi Yun ) 한국컴퓨터교육학회 2011 컴퓨터교육학회 논문지 Vol.14 No.4

본 연구는 디지털 교과서를 수용하는데 영향을 미치는 변인들과 그 구조를 규명하고자 수행되었다. 교사들의 혁신성에 근거하여 디지털 교과서의 수용 전략을 수립하기위해서 캐즘 이론을 검토하고, 디지털 교과서 등 교수매체 수용의 의사결정을 설명하는 정보기술수용모형을 본 연구에 적용하였다. 캐즘이론과 정보기술수용 모형을 토대로 조사도구를 제작하였으며, 신뢰도 및 타당도 검증을 거쳐 혁신성, 지각된 유용성, 지각된 사용용이성, 사용의도 간의 인과적 관계 검증을 수행하였다. 구조방정식(SEM)을 사용하여 본 연구의 구조모형을 검증한 결과 지각된 사용용이성은 지각된 유용성에 직접적인 영향을 미쳤고, 사용의도에는 간접적인 영향을 미쳤으며, 지각된 유용성은 사용의도에 직접적인 영향을 미친 것으로 나타났다. 이러한 연구결과는 디지털 교과서 수용을 위한 전략 수립에 구체적인 시사점을 준다. 즉, 디지털 교과서의 일반학교 도입은 보다 신중하게 검토되어야 하며, 인터페이스의 개선과 같은 사용 용이성보다는 디지털교과서의 유용성에 초점을 맞추는 정책적 노력이 필요하다는 것이다. This study was conducted to identify factors that influenced teachers` adoption of digital textbooks and causal relationships among the factors identified. Chasm theory was used in developing strategies for adoption of digital textbooks that consider teachers` innovativeness. This study also employed the information technology adoption model of Davis (1989) that illustrates decision making processes for the adoption of instructional media such as digital textbooks. Based on these two theories, a measurement instrument measuring teachers` innovativeness, perceived usefulness, perceived ease of use, and intention of use was developed and validated through a series of reliability and validity tests. Causal relationships among the factors were examined using structural equation modeling. The result indicated that: a) perceived ease of use had a directional effect on perceived usefulness and an indirect effect on intention of use; and b) perceived usefulness had a direct effect on intention of use. Implications of this finding are discussed especially for the efforts in developing strategies for teachers` adoption of digital textbook. For example, when digital textbooks are introduced into public schools, teachers` perception of the usefulness of digital textbooks, beyond just ease of use, should be considered.

서순식(Soon-Shik Suh),김성완(Sung-Wan Kim) 한국컴퓨터정보학회 2011 韓國컴퓨터情報學會論文誌 Vol.16 No.10

이 연구는 교원 정보화 역량강화 연수과정 내용 및 운영에 대한 현황조사 및 연수과정에 대한 온라인 설문조사, 연수과정 운영자 심층면담 등을 토대로 기존 교원 정보화 역량강화 연수의 운영 성과를 분석한 것이다. 이 연구를 바탕으로 차세대 교원 정보화 연수개발을 위한 현 연수과정의 개선방안을 제시하였다. 온라인 설문조사 결과에 따르면, 현행 교원 정보화 역량강화 연수과정은 전체적으로 바람직하게 운영되고 있다고 볼 수 있다. 다만, '사고력 신장을 위한 ICT활용 교육 과정', '미래로 가는 교육 과정', 'ICT활용 문제중심학습 과정'과 같이 보통수준이라고 응답한 비율이 비교적 높은 과정에 대해서는 운영과정의 효과성과 효율성 제고를 위한 노력이 요구된다. 특히 목표의 실천가능성, 수준별 고려여부, 연수 장소 및 교통편 등의 접근성, 맞춤형 수준별 전략 등의 하위평가영역은 타 영역에 비해 낮게 평가되었다. 또한 교원 정보화 역량강화 연수운영자에 대한 심층면담 결과, 이들은 교육현장 요구반영에의 필요성, 강사 재훈련 및 자기계발기회 제공, 지역 전달 연수의 질 관리, 해외 연수사례 국내화 과정에서 특성화, 연수기간의 확대, 연수 후 후속지원의 필요성 등을 제안하였다. The purpose of this study is to analyze the results of training programs for strengthening teachers' ICT competency and to suggest the ways to improve the existing ones. To do this, we conducted literature review, web survey with teachers, and in-depth interview with training program operators. The results of the online survey indicated that generally speaking, the programs had been operated desirably, although three programs(Thinking with Technology Course, Essential Course, e-PBL Instructional Design Course) needed to take additional efforts for their effectiveness and efficiency. According to the results of in-depth interview with training operators, they demanded re-training for lecturers, self career development, quality control of regional delivery training, expansion of training periods, and post-supports after training etc.

서환조,신완식,강문원,이정희,정희영,이학중,박성수,이홍순 대한감염학회 1984 감염 Vol.16 No.1

Cefoperazone is a new piperazine cephalosporin derivative which has a broad antibacterial activity against aerobic & anaerobic gram-negative cocci and bacilli, including P. aeruginosa. A total of 75 patients with a variety of respiratory tract infections were treated with Cefoperazone. The drug was administered intravenously in dose of 4∼6g per day for 7 to 14 days. The clinical response was satisfactory in 46 (70.0%) of 65 patients with pneumonia,5 (70.1%) of 7 with bronchiectasis complicated by infections, 2 (50%) of 4 with infections secondary to chronic respiratory disease, 1 with pyothorax, 1 with severe chronic bronchitis. Overall, Cefoperazone was effective in 54 (72.0%) of all patients treated. Adverse effects-mainly fever, rash-occurred in only 4.0%, and abnormal results of laboratory test-mainly elevation of hepatic enzyme levels-occurred in 4.0% of all patients treated. But it is doubtful whether these adverse effects are related to Cefoperazone or not.

전자학습(e-러닝)에서 학생들의 학습 촉진을 위한 메시지 제시 전략 탐구

서순식 연세대학교 교육연구소 2006 미래교육학연구 Vol.19 No.2

전자학습(e-러닝)은 정보통신네트워킹에 의해 창조되는 전자공간을 기반으로 교수학습이 진행되는 교육체제이며, 면대면 교수학습 상황과는 구별되는 고유한 상징체계(symbol system)를 갖는다. 전자학습체제의 화면설계를 위해서는 학습 목표 달성을 위한 필수적인 학습내용을 선정하고, 학습자ㆍ교수자간에 개별화된 상호작용을 위한 전략을 고안해야 한다. 이를 위해서 정보처리이론에 근간을 둔 전자학습 콘텐츠 설계 및 개발 전략을 살펴볼 필요가 있다. 이 연구의 목적은 전자학습 환경에서 학습자의 적극적인 인지활동을 촉진하고 깊은 수준의 이해 촉진을 위해서 어떻게 학습콘텐츠를 설계하여야 하는가에 대한 실천적 시사점을 규명하고자 하는 것이다. e-Learning delivered through the cyber space is a new educational system and has different characteristics from offline education. In order to overcome the weaknesses of the offline education, such as lack of individualized interaction, and to offer effective learning contexts, this paper introduce the six strategies for designing the interface of e-Learning program. The strategies are below: 1. Applying the multimedia principle: use words and graphics rather than words alone; 2. Applying the contiguity principle: place corresponding words and graphics near each other; 3. Applying the modality principles: present words as audio narration rather than on-screen text; 4. Applying the redundancy principles: presenting words in both text and audio narration can hurt learning; 5. Applying the coherence principle: adding interesting material can hurt learning; 6. Applying the personalization principles: use Conversational Style. In this paper, research results regarding the best use of media elements, such as sound, graphics, and text are summarized. Also, the discussion of the specific implications to design and develop e-Learning contents based on information-processing theory are described.

한국과 싱가포르의 개발부담금제 비교연구

서순탁(Suh Soon-Tak),최명식(Choi Myung-Shik) 한국공간환경학회 2010 공간과 사회 Vol.33 No.-

토지개발을 통한 우발이익은 불로소득적 성격이 강하여 사회적으로 많은 문제를 야기시킨다. 이에 따라 세계 각국에서는 이의 환수를 위한 다양한 정책들을시행하고 있다. 우리나라에서는 개발부담금 제도가 개발이익 환수를 위한 직접적 이고 대표적인 수단으로 시행되고 있다. 그러나, 현재 개발부담금 제도는 개발이익환수수단으로서의 역할이 부족하다고 판단되며, 운영상 많은 어려움에 부딪히고 있다.따라서, 본 연구에서는 해외 선진사례로 널리 인식되고 있는 싱가포르 사례를구체적으로 분석하여, 한국의 개발부담금제와 비교를 통해 개발부담금제도 개선을 위한 정책적 시사점을 도출했다. 이를 위해 먼저 개발이익환수체계 전체적인관점에서 개발이익 환수의 배경, 개발이익 환수 방법, 개발부담금제의 위상, 개발부담금 산정방법, 개발이익환수체계를 비교?분석했다.연구 결과 향후 한국의 개발부담금제가 싱가포르와 같이 성공적으로 정착하기위해서는 쉽고 간단?명료한 개발부담금제의 시행으로 납부의무자의 개발비용 예측이 가능하도록 하고 징수주체인 공무원의 업무부담을 해소하며, 부담금의 객관성을 확보하여 효율적으로 제도운영을 해야 가능할 것으로 기대된다. Since the windfall gain from land development is regarded as an unearned income, it causes a lot of problems in our society. Therefore, a variety of policies to recapturea wind fall gain are being implemented in many countries, and Korea also has the development charge system as a direct and typical way of it. However, the development charge system of Korea has a bunch of limitations on recapturing windfall gains, and is confronted with several operational problems. In this sense, the aim of this paper is to get policy implications about the development charge system of Korea by comparing with the case of Singapore, which is commonly considered as one of the best cases in the world. In order to achieve this goal, first of all, a comparative analysis about the background and methods of recapturing a windfall gain, and the institutional position of the development charge system is implemented in terms of the comprehensive windfall gain recapturing system. After this, we analyze the development charge system itself according to some specific criteria, and finally, we compare the methods of estimating development charge of two countries. The result of this paper indicates that the development charge system needs to be simplified and be easier in order to let the system embed successfully in Korea like Singapore. To put it more concretely, the system can be managed effectively by making taxpayers be able to predict the exact cost of development, reducing the burden of collectors, and ensuring the objectivity of the charge. Therefore, it is expected that this paper has a role as a fundamental data for amendment of a relevant law and rearrangement of the development charge system in Korea.

무우에 함유된 Peroxidase의 효소학적 특성

朴仁植,徐慶順 東亞大學校 大學院 1988 大學院論文集 Vol.13 No.-

Peroxidase(EC1.11.1.7) was partially purified from Korean radish by CM-Sepharose CL-6B, gel filteration on Sephacryl S-200 and DEAE-Sephacel column chromatography. The molecular weight of the enzyme was estimated to be about 34,000 by gel filtration on Sephacryl S-200. The optimal conditions for the enzyme reaction were pH6.5 and temperature of 65℃.The enzyme was very stable by heating at 60℃ for 30 munutes, while almost 91.2% of enzyme zctivity was lost by heating at 75℃ for 30 minutes. Kivetic studies indicated a K?? of 0.40mM for hydrogen peroxide at fixed phenol concentration, and a K?? of 67mM for phenol at a fixed hydrogen peroxide concentration . The peroxidase activity was enhanced by addition of pb???? and Mg????, respectively, meanwhile Mn??, Ca??,Fe??, K??, and Ag?? inhibited the enzyme significantly.
