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.

서현정 ( Seo Hyun-jung ) 한국공공언어학회 2021 공공언어학 Vol.6 No.0

이 연구의 목적은 공공언어에 사용되는 이해하기 어려운 외래어 외국어의 특성을 분석하고, 이를 진단하는 실효성 높은 기준을 제안하는 것이다. 이를 위해 기존 외래어 외국어 사용 관련 진단 기준을 검토하여 실효성을 살펴보고, 공공언어 생산 주체인 공무원들이 공공언어 생산 과정에서 참고할 수 있는 지침으로서의 진단 기준이 보완될 필요가 있다고 보았다. 또한 2020년 서울시 공공언어 실태조사 결과를 검토하여 부서명, 정책명 등의 공공언어에서 사용되는 외래어 외국어의 특징을 분석하였다. 공공언어의 외래어 외국어 사용의 주된 특성은 사용자 편의성에 따른 의미적 포괄성(다의성), 추상성, 모호성이라 할 수 있으며, 수용자 편의성으로 전환하기 위해서는 구체성과 명확성을 확보해야 함을 강조하였다. 그리고 공공 언어에서 사용되는 외래어 외국어에 대한 공무원들의 인식을 살펴 보기 위해 공무원 6명을 대상으로 서면 인터뷰를 실시하였다. 그 결과 외래어 외국어 남용을 개선할 필요성에 대한 공감대를 확인하였으며, 인터뷰에 참가한 공무원들은 공공언어 생산 과정에서 참고할 수 있는 지침으로서의 진단 기준의 필요성에도 깊이 공감하였다. 본고에서는 수용자 중심의 공공언어를 위해 외래어 외국어 진단 기준에 포함해야 할 항목으로 포괄적/다의적/불명확한 외래어 외국어 사용 여부, 다듬은 말(순화어) 사용 여부, 로마자 표기 여부, 표준국어대사전 등재 여부 등을 제시하고, 다듬은 말 목록에 대한 대대적인 정비가 선행되어야 함을 강조하였다. 또한 공문서 생산자들이 문서 작성 과정에서 참고할 수 있는 점검표의 예를 제시하였다. 공공언어의 외래어 외국어 사용에 대한 진단 기준은 공공언어 평가를 위한 기준이면서도 공공언어 생산 과정에서 참고할 수 있는 점검 사항으로서의 진단 기준이 되어야 하며, 무엇보다 수용자가 쉽고 명확하게 이해할 수 있도록 ‘용이성’ 범주에 의미의 명확성을 중요한 세부 기준으로 포함해야 한다. The purpose of this study is to analyze the characteristics of foreign languages, which are difficult to understand, used in public languages, and to propose a highly effective standard for diagnosing them. To this end, the effectiveness of the existing foreign language use-related diagnostic criteria was reviewed, and the diagnostic criteria as a guideline for public officials, who are the main actors of public language production, need to be supplemented. Also, by reviewing the results of the 2020 Seoul Public Language Survey, the characteristics of foreign languages used in public languages such as department names and policy names were analyzed. The main characteristics of foreign language use in public languages are semantic inclusiveness (multiple words), abstraction, and ambiguity according to user convenience. In addition, in order to examine public officials' perceptions of foreign languages used in public languages, written interviews were conducted with six public officials. As a result, a high consensus was confirmed on the abuse of foreign languages in foreign languages, and the public officials who participated in the interview deeply sympathized with the need for diagnostic standards as guidelines that can be referenced in the public language production process. In this paper, as items to be included in the foreign language diagnosis criteria for a prisoner-centered public language, it is suggested whether a foreign language is used in a comprehensive/multiple/ambiguous foreign language, whether to use refined words (purified words), whether to use Roman characters, and whether to be listed in the standard Korean dictionary. and emphasized that a major overhaul of the trimmed horse list should be preceded. In addition, an example of a checklist that producers of public documents can refer to in the process of preparing documents is presented. The diagnostic criteria for foreign language use of foreign languages in public languages should be the criteria for public language evaluation and as a checklist that can be referenced in the public language production process. More than anything, clarity of meaning should be included as an important detail criterion.

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.

한국 전통사회의 유아교육에 관한 일 연구

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.
