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.

In this study, we progressed flame retardant performance evaluation of wood-based materials, which were applied with carbon materials. We analyzed using a cone calorimeter according to ISO 5660-1 standard. Also, we proceed to the TGA experiment for confirming the thermal property of graphite and exfolied graphite nano pletelets (xGnP) applied as flame retardants. The value of the heat release rate of all specimen applied with xGnP were not exceed 200 kW/㎡ during the total testing time of 5 minutes corresponding to the flame-retardant Level 3. The value of the heat release rate of all specimen applied with xGnP were not exceed 200kW/㎡ during the total testing time of 5 minutes corresponding to the flame-retardant Level 3. And in this experiment, the value of heat release rate of the specimen, which was applied to 4 wt% of xGnP, showed a relatively low value. The case of the value of total heat release, the value of the specimens, which were applied with xGnP, showed lower than the non-treated specimens’. Also, it was confirmed that the slopes of the graph of the specimens were applied with xGnP, were lowering after 300 seconds. Through the results of TGA measurements, we confirmed the thermal properties of graphite and xGnP, and determined that the materials had the thermal stability through the results of the mass loss rate in fact less likely. Based on these results we were confirmed xGnP was contributed to improved flame retardant performance of woodbased materials.

As one of the Korean traditional foods, rice cake, which is called "tteok" in Korean, has a variety of tastes, flavors and colors and is regarded as a macrobiotic diet since it is cooked with ingredients in season. Recently, as people"s dietary life environments change due to westernization and nuclear families, it is true that the manufacture and use of rice cake are actually on the decline. Accordingly, this study aims to investigate the actual conditions of adults" awareness and preference for rice cake as well as perception and intake of rice cake by age, with a total of 289 survey participants from the Daegu region, further seeking a relevant plan to develop and inherit rice cake, a Korean traditional food. As for the preference for rice cake, adults in their 20"s showed the highest preference for songpyeon and adults between their 30s and 40s and between their 50s and 60s for injeolmi, but there was a significant difference (p<0.05) found between songpyeon and gyeongdan. As for the intake of rice cake , adults in their 20s showed the highest frequency in "about once every 3 to 6 months", and adults between their 30s and 40s and between their 50s and 60s showed the highest frequency in "about once or twice every month", so that there was a significant difference (p<.0001) between them. As for the kinds of rice cake, their 20s showed the highest preference for songpyeon and adults between their 30s and 40s and between 50s and 60s showed the highest preference for injeolmi. 97.6% of the research subjects responded that it is needed to inherit and develop rice cake, but the frequency of taking in rice cake was relatively low, such as adults in their 20s responded "about once every 3 to 6 months" and adults between their 30s and 40s and between their 50s and 60s responded "once or twice every month". As a result, it seems necessary to seek for various developmental plans, such as developing more kinds of rice cake by reflecting different age groups" preference for rice cake and to carry out constant promotion and research on rice cake in order to increase adults" frequency of taking in rice cake and to inherit and develop rice cake.
