목적: PEG 용액은 안전하고 정결 효과가 우수하여 현재 임상 에서 대장내시경 전처치제로 가장 널리 사용되고 있지만, 특 유의 짠맛으로 환자의 순응도가 낮다는 제한점이 있다. 이번 연구는 이러한 단점을 보완하기 위해 표준 PEG 용액에 설탕 을 첨가하여 복용하도록 한 후 대장 정결 효과 및 환자 순응도 를 표준 PEG 용액을 복용한 군과 비교 분석하고자 하였다. 대상 및 방법: 2012년 1월부터 6월까지 강릉아산병원 소화기 내과에서 대장내시경을 시행받은 총 100명의 환자들에 대해 무작위 전향적 대조 연구를 진행하였다. 대장 정결은 표준 PEG 용액 4L 또는 설탕을 첨가한 PEG 용액 4 L 중 한 가지 로 무작위 배정하였다. 시술자 설문지를 통해 대장 정결도와 내시경의의 검사만족도를 조사하였고, 환자 설문지를 통해 순 응도를 조사하였다. 결과: 두 군 사이에 대장 정결도(4.2±2.0 vs. 4.1±1.5, p=0.783)와 내시경의의 검사만족도(8.2±1.8 vs. 8.5±1.3, p=0.253)는 유의한 차이가 없었으나 환자의 역겨움의 정도 는 설탕첨가 PEG군이 3.9±2.9로 표준 PEG군 6.4±2.3과 비교하여 볼 때 역겨움의 정도가 낮았으며(p<0.05), 같은 방 법으로 재검사하겠다는 응답도 설탕첨가 PEG군이 2.3±0.7 로 표준 PEG군 2.0±0.6보다 높았다(p<0.05). 전처치제를 복용하면서 느낀 주관적 불편감은 두 군 사이에 유의한 차이 가 없었다. 결론: 설탕을 첨가한 PEG 용액은 효과적인 대장내시경 전처 치 방법이며 표준 PEG 용액을 복용할 때 짠맛으로 인해 복용 의 어려움을 호소하는 환자에게 좋은 대안이 될 수 있을 것으 로 기대된다. Background/Aims: Although polyethylene glycol (PEG) solution is commonly used for colonoscopic bowel preparation because of its safety and effectiveness, its salty taste decreases patient`s compliance. The aim of this study was to compare the sugared PEG solution with the standard PEG solution in regard to the quality of bowel preparation and patient`s compliance. Methods: From January through June in 2012, 100 patients who underwent colonoscopy in Gangneung Asan Hospital were prospectively enrolled. They were randomly assigned to receive either standard PEG solution or sugared PEG solution. The quality of bowel preparation was assessed by a doctor`s questionnaire and the patient`s compliance was assessed by a patient`s questionnaire. Results: There was no significant difference in the quality of bowel preparation (4.2±2.0 vs. 4.1±1.5, p=0.783), and endoscopist`s satisfaction score (8.2±1.8 vs. 8.5±1.3, p=0.253) between two groups. However, The degree of disgust was lower in the sugared PEG group than the standard PEG group (6.4±2.3 vs. 3.9±2.9, p=0.000). The willingness to repeat same regimen was higher in the sugared PEG group than the standard PEG group (2.0±0.6 vs. 2.3±0.7, p=0.004). There was no difference in side effects between two groups. Conclusions: The sugared PEG solution as a bowel preparation method revealed a higher patient`s compliance and was effective as the standard PEG solution. When the patient dislike the taste and saltness of the standard PEG solution, the sugared PEG solution will be good alternative method.

DualModel에 기반한 전자세금계산서 발행시스템 수용에 관한 연구

서현식(Hyun Sik Seo),송인국(In Kuk Song) 한국경영학회 2011 經營學硏究 Vol.40 No.5

With rapid advances in IT and the Internet technologies, the scope of business-to-business electronic commerces has been dramatically increasing. This led the needs of electronic delivery for the various tax invoices and finally brought into being many ASP(Applicaiton Service Provider) agents that provided ETIS (Electronic Tax Invoice Systems) via the web as a service. Since early 2011, Korean Government has obliged the corporations to use ETIS, in order to reduce the compliance cost in the corporation tax, improve the business processes, and increase the productivity. However many researchers point out that researches analyzing the potential risks and benefits of ETIS rarely exist. The purpose of the study is to examine the acceptance of the ASP services for ETIS and to propose the improvement plans of the services. The study presents the results of a rigorous research efforts to investigate the benefits and costs for ETIS from agents` standpoints. A dual model was applied to the ASP services for ETIS because the expectation and risk of ETIS tended to simultaneously occur. The study proposes a set of hypotheses, inducting the relationships with the intention to use ETIS and comparing the benefits and risks of ETIS. To test the research model and hypotheses, the study targeted ASP users requesting electronic tax invoice services via the web. All dimensions of the dedications and constraints factors were generally or operationally defined and measured using the 7-point Likert scale. To ensure the content validity and reliability of the survey questionnaire, the pre-tests and test-retests were performed. The survey data was collected to capture the respondents` subjective perception for the identified variables. The study utilized a structured equation model to structure data collection and establish the various paths to the intention to use ETIS. After collecting the survey data, the proposed model and paths were analyzed using the smart PLS package. Findings indicate that the increased productivity through business process innovation using ETIS satisfies the expectation of the agents and sequentially leads to the dependancy for the ASP agents and continuous use of ETIS systems. In addition, the significant implication of findings is that although the scramble for poor ASP agents leads to switching costs, the corporations using ETIS are willing to pay switching costs in the short view. This implication illustrate how the corporations sequentially accept the ETIS. On the other hand, it could not be confirmed by the results that the dependence for ASP agents leads to the trust for the agents and that the trust results in the intention to use ETIS. The study stresses the significance of switching costs and willing to pay in the short view to make the corporation enhance the intention to use ETIS. Despite of a couple of limitations to which the study confronts, the study would contribute especially when the Korean government is willing to refer in vitalizing the electronic tax invoice policy. Since the ASP for ETIS is still in the early stage, and studies researching the acceptance of ETIS rarely exists, the study may provide both practical and theoretical framework for future research.

순화어 확산을 위한 카드뉴스 제작 전략과 댓글에 나타난 독자 반응 양상

서현정 ( Seo Hyun-jung ) 한국공공언어학회 2021 공공언어학 Vol.5 No.0

본고의 목적은 순화어 인식 확산을 위한 카드뉴스의 사용 전략을 분석하고, 댓글을 분석하여 온라인 매체 독자들의 반응 양상을 살펴보기 위한 것이다. 최근 공공언어 사용 실태 조사 결과를 보면 여전히 정책 용어, 행정 용어에 지나치게 어려운 한자, 외국어, 외국 문자를 사용하는 문제가 지적되고 있다. 공공언어의 실질적인 개선을 위해서는 국어 순화 정책의 방향과 목적을 보다 구체화하고 순화어 사용에 대한 공감대를 확대해야 한다. 본고는 순화어 사용의 필요성과 의미에 대한 인식을 제고하기 위한 방안으로 '카드 뉴스'를 제안하고, 카드 뉴스 사용 전략으로 다양한 관점을 고려한 카드뉴스의 대상어 선정, 정보 전달과 설득의 균형, 연관성이 있는 구체적인 상황 제시, 명확하고 간결한 표현과 구성, 시각적 이미지의 적절한 활용 등을 제시하였다. 또, 카드뉴스에 대한 독자의 댓글을 분석한 결과, 대체로 독자 반응에서 긍정적인 수용 양상을 나타내는 댓글이 48개(60%)로 많았다. 부정적 인식을 드러내는 댓글 내용은 순화어 인식을 위해 선행되어야 할 점이 무엇인지, 순화어 사용 확대를 위해 고려해야 할 사항이 무엇인지를 시사하였다. 단순히 ‘외국어이기 때문에 사용해서는 안 된다’와 같은 근거가 아니라 순화 대상어가 소통에 어떤 영향을 미치는지 적극적으로 밝혀야 하며, 다양한 사용 맥락을 고려하고 단순 번역식의 순화어가 아니라 포괄적 쓰임과 목적을 고려하여 순화어를 마련할 필요가 있다. This paper is a study to examine the reaction patterns of readers of online media by analyzing the strategy of using card news to disseminate refined words, and analyzing comments. Looking at the results of the recent survey on the use of public languages, the problem of using Chinese characters, foreign languages, and foreign characters, which are still too difficult in policy terms and administrative terms, continues to be pointed out. In order to substantially improve the public language, the direction and purpose of the Korean language refining policy should be more specific and a consensus on the use of refined words should be expanded. This paper proposed ‘Card News’ as a way to raise awareness of the necessity and meaning of the use of refined words and suggested strategies for using card news. In this paper, in order to spread the positive perception of refined words, strategies such as selection of refining target words for card news considering various perspectives, balance of information delivery and persuasion, presentation of specific situations that can relate to, clear and concise expression and composition, and use of appropriate visual images. It has been suggested that card news can be used. Readers' comments on card news were analyzed to see their responses, and in general, there were 48 comments (60%) that showed positive acceptance patterns in reader responses. The content of comments revealing negative perception suggested what should be preceded for the recognition of refined words and what should be considered for expanding the use of refined words. It is not simply the basis of 'it should not be used because it is a foreign language', but actively discloses how the target language has an effect on communication, considers a wider range of usage contexts, and considers the comprehensive use and purpose of the purified language rather than a simple translation. It needs to be prepared.

Korean traditional society is defined as the period from the Three-country period to 1897 before kojong declared the change in country name to Daehan Empire. Prior to Three-country period the outline of existing education consisted of life training, religious education, military training, and production training. After the Three-country period, through buddhism, advanced religion and philosophical thought began to form. Furthermore, school education began through confucianism an therefore buddhism and confucianism have had an absolute influence on the formation of the korean values. This study will focus on investigating the reality of the educational insight of Koreans by observing early childhood educational thinking at different time periods in traditional Korean society and presenting contemporary educational tasks. The conclusion based on reference studies regarding the focus described above is as follows: From the Three-country period to the koryo dynasty, it is believed that care and education were based solely on the teachings confucianism and/or buddhism. Also during the chosun dynasty education was informal in nature and was considered to begin with prenatal influence. It was also observed that prenatal influence of the father was emphasized as strongly as that of the mother. Through the view of child and view of child education of traditional korean society based on the view of human being of confucianism, although there was evidence of the respect for children it was not fully practiced and it was observed that the respect for children did not continue into education as child centric thinking. The focus of education during the chosun dynasty was in moral education. Therefore the ultimate focus was on cultivating well-behaved, educated individuals and moral education was defined as the unity of thought and behavior. Korea is a country rooted in deep traditions dating back thousands of years and the child was viewed ad a precious member of traditional society. Even so the value system of our ancestors has been largely ignored while we rushed to assimilate to western culture. Now it is time to put effect into utilizing traditional value systems and thoughts as the foundation of education in research education facilities. It is necessary to foster understanding and pride in our traditional culture beginning from early childhood in order to rise as a leading nation in the world and prepare for globalization. This is the time to adopt our forefathers beliefs of respecting the child and recognizing prenatal influence and even the fetus as a precious being for the well-rounded development of our children. The early childhood education of traditional society as discussed above is based on the basic principles recognized today as important in the stages of development such as early education, life training, education by example, and education for specialized development. Therefore even in respect to contemporary education its application and appropriateness must be recognized. Although child-care methods carried down from traditional societies have diminished, this generation needs to find those methods helpful to the well-rounded development of children in and effort to raise the future leaders of this country.

Facing the knowledge development, information expansion and increase in educational population along with the modern, information-oriented society, we are required to improve the quality and method of teaching and learning. In other words, we should develop and utilize various media for effective teaching and learning which lead to the maximization of educational effects and promotion of learning interests and motives. Children usually have undeveloped attention and concentration. For them, therefore, suitable audio-visual media are needed to foster their interests in learning. Very importantly, such audio-visual media could attract children to learn positively and effectively because the media are arranged according to children's developmental difference. There have been studies about teachers' recognition and utilization of audio-visual teaching media, often at the levels of primary, middle and high schools. The studies showed that most of the teachers were positive about the media and effects of such media for learning objectives, but little capable of manufacturing the educational materials. Few similar studies have been so far made to kindergarten teachers. So, this researcher surveyed the current use of audio-visual teaching media at each activity of pre-school education. As a result, it was found that kindergarten teachers had little use of the media. Fully considering findings from all of the studies as above mentioned, the researcher could reach the following conclusions and suggestion. First, teachers recognize audio-visual teaching media very clearly, but use few of the media in the actual situation of teaching. Second, there are differences among teachers about the extent to which they use audio-visual teaching media, in accordance with the teachers' professional career. Third, teacher are little excellent in the operation and preparation of such teaching media. Regarding the operation and preparation, longer service teachers are relatively better than the others. Fourth, audio-visual teaching media vary In patterns and learning effects according to the capacity of relevant school. Fifth, the application of the media requires training program development and training opportunity increase. Sixth, audio-visual teaching media are little used In actual education because they are not still easily available. Seventh, administrative and financial supports should be given to help the development of very effective, up-to-date and practical materials of education.
