인터넷의 급속한 확산에 따라 사회 전반의 디지털화와 지식정보화가 급속도로 진행되고 있다. 특히 많은 사용자들은 웹상에서 다양한 작업을 하고 서비스를 이용하고 있다. 이러한 작업들의 대부분은 XML을 이용한다. XML은 개발자가 필요시 문서의 논리구조를 정의할 수 있으며, 내용과 스타일이 분리가 되어 있어서 문서의 재사용성이 뛰어나다. 하지만 XML은 기본적으로 문서의 내용을 단순히 텍스트 형태로 다루고 문서의 구조를 표현하기 위해 많은 태그들이 추가되기 때문에 문서의 크기가 커질 수밖에 없다. 팜탑, PDA 등의 제한된 용량을 보다 잘 활용하기 위해서는 문서를 효율적으로 압축해서 사용할 필요가 있다. 이를 해결하기 위해 최근 XML문서를 효과적으로 압축하고 다루기 위한 XML 압축 기법에 대한 연구가 일부 이루어지고 있지만, 기존 연구들의 대부분은 압축된 XML 문서에 대한 질의 처리를 고려하지 않았다. 이에 본 연구에서는 기존의 방법들보다 효과적으로 압축을 하여 저장 공간의 효율성을 높이고, 압축된 XML 문서에 대해 질의 처리를 가능하게 하여 보다 빠른 질의 처리를 할 수 있는 XML 압축 알고리즘을 설계 및 구현하고자한다. With the spread of internet, the digitalization and knowledge-based information are in progress. Specially, numerous users make the various works and use the services on the web. For the most part, these works make use of the XML. The XML shines the reusing of the Documents because it is separated from contents and styles. Also, it can re-define the logic structure of the Document for requirement of the developer. However, the XML document's size is much larger than common text document because it basically handles the document type and adds numerous tags for representing structure of the document. To utilize the limited storage of Palmtop, PDA and so on, it is necessary to compress and handle the documents efficiently. Recently, the compression techniques for efficiently handling and compressing the XML documents are in progress to solve this problem. But the existing research doesn't support the query processing for that. In this paper, we design and implement the XML compression algorithm that compresses the XML document and processes the query of compressed XML document faster and more efficiently than the previous techniques.

본 연구에서는 전기렌터카 이용자가 충전소 대기수요로 인해 다른 충전소를 찾은 경험이, 전기렌터카 이용 만족도와 전기차에 대한 인식 변화에 주는 영향을 분석하였다. 전기렌터카 이용실태 설문조사 자료를 이용하여 분석을 수행하였고, 이 자료의 유효표본수는 196명이다. 분석을 위해 전기렌터카 이용 만족도에 대한 최소제곱 모형과 전기차 인식 변화에 대한 평균처리효과 모형을 설계하였다. 분석결과, 최소제곱 모형에서는 충전소 회차 경험이 전기렌터카 이용 만족도에 부정적인 영향을 미치는 것으로 나타났다. 평균처리효과모형에서는 회차 경험자의 전기차에 대한 인식변화가 회차 비 경험자에 비해 부정적인 것으로 나타났고, 회차 경험자 자신이 회차를 경험하지 않았을 때를 가정하여 비교하면, 인식 변화가 더욱 부정적인 것으로 나타났다. 이러한 연구결과는 제주도 내 더 많은 개방형 충전기의 확충, 숙박업소 내 충전기 설치기준 마련과 충전기 보급지원, 전기렌터카 예약 단계에서 충전소 정보제공 시스템화 등의 필요성에 대한 시사점을 제공한다. This study analyzes user satisfaction and perception change toward electric rental cars if an electric rental car user has encountered queue in a charging station and navigated other available stations. An ordinary least squares model of electric rental car user satisfaction and an average treatment effect model of perception change toward electric vehicles are specified. Using behavioral data collected from a survey of 196 electric rental car users, the models are estimated. Results show that the experience of turning back in a charging station has negative effect on user satisfaction and perception change toward electric vehicles. These results provide policy implications as follows: more public chargers are needed in Jeju; the installation of chargers should cover hotels; and more information on chargers should be available, including the location of charging stations.

김기택 시 연구를 위한 시론 : 반(反) 속도의 미학

Kim Gi-Taik is a poet who actively writes poems after 1990's. Kim Gi-Taik poetry study has not been conducted seriously because literary-study is possible after securing objective distance. However, since a full-scale study of his poetry can be made abundantly on the basis of various sights and viewpoints, a new approach should be taken to the research of Kim Gi-Taik poetry. Kim Gi-Taik poetry study which has been carried out until now focuses on only the materialism of the flesh and the phenomenology of the body, and other approaches of the poetry do not exist. So, this article will access the poetry through another method and find the motive of the poetry. It is the resistance against the speed that this article finds the motive of his poetry. The motive is categorized into three types. The first type expresses the imagination of the stop, disintegration, and return in order for the narrator to have time for introspection and self-reflection. The second type shows the motive of 'slowness and traces' as the resistance against the speed. The last type reveals that the poetic narrator values the pre-language sounds rather than grammatical language in communication. In the most Kim Gi-Taik poetry, the poetic narrator chooses non-effective, non-quick, but vital pre-language which sounds better than the effective, quick, reasonable, and grammatical language. In conclusion, Kim Gi-Taik poetry actively materializes the motive of 'anti-speed' as the strategy of his poetry.

Collagen has been used as a functional material for foods and medicines, and has a function of enhancing the moisture retention of the skin. Now it is widely used in a variety of fields such as base materials for cosmetics. Therefore, it is expected that the demand for collagen and its application will be greatly expanded. This study was performed to investigate the physicochemical characteristics of glycoprotein extracted from cucumber. we manufactured glycoprotein using natural vegetable raw materials cucumber, and then analyzed physicochemical properties, analysis of the amino acid composition of cucumber collagen and compare with squid’s collagen. The content of aspartic acid was about 3 times as much as that of cucumber 18.57 wt% and squid 5.32 wt%. It was possible to check the fact that not only aspartic acid but also glutamic acid contains much more vegetable collagen than animal collagen. For example, cucumber contains 19.03 wt% glutamic acid. Otherwise, squid contains 7.5 wt% respectively. Moreover, the pH change was measured at a weekly rate of 25 °C and 37 °C for 8 weeks. At 25 °C, the cucumber collagen peptide remained very stable because of no pH change. After 8-week observation at a temperature of 37 °C, pH level is reduced by 0.5, suggesting that it have been demobilized by the amino acid component of the collagen. After analyzing the mass analysis, collagen had a molecular weight distribution below 281 Da. Considering that the molecular weight that can be absorbed into the skin is from 2000 Da, it is found that the vegetable collagen is a good biomaterial of absorbent material in the skin.

Purpose: The high mortality and morbidity rates associated with traumatic rupture of the small bowel have been attributed to the clinical difficulty of establishing an early diagnosis. CT scan is the most widely used tool for the diagnosis of blunt abdominal trauma, but its accuracy in diagnosing small bowel perforation is still controversial. This study was conducted to determine the overall and time-dependent diagnostic value of abdominal CT and the clinical findings of small bowel perforation. Methods: The clinical data and CT images of 21 patients with small bowel perforation after blunt trauma were retrospectively analyzed. The patients were divided into the early and late elapsed time groups based on the elapsed time of 8 hours from the initial trauma to the time of evaluation. Results: Any changes of the vital signs, including hypotension, tachycardia or fever, were observed in only half of the patients. Signs of peritonitis were evident in 7/11 of the early lapse group and in 10/10 of the late lapse group. The most common CT finding of small bowel perforation was free peritoneal air (17 of 21 patients), followed by segmental bowel wall thickening (15/21), high density ascites (14/21), an intermesentric fluid collection (13/21) and mesentic fat obliteration (11/21). Extraluminal air and segmental bowel wall thickening were detected more frequently in the late lapse group (P=0.03 and 0.01, respectively). In the one patient, bowel perforation was not evident at the initial evaluation according to the clinical findings and CT, but the follow-up CT exam showed specific findings for bowel perforation. Conclusion: CT scanning is a sensitive and effective modality for the evaluation of small bowel perforation, but this is less sensitive during the earlier post traumatic period. Therefore, careful clinical and radiological follow up is necessary for suspected cases, and even when an initial evaluation shows negative findings for bowel injury.

본 연구는 CFI 2030 추진에 따른 2024년부터 2030년까지의 제주지역 태양광과 풍력발전의 출력제어 규모를 단계별 가정을 통해 예측하고, 출력제어 전력을 활용하여 생산 가능한 그린수소의 양을 산출하였다. CFI 2030의 신재생에너지 발전설비 도입 목표가 2024년부터 계획대로 달성된다고 가정할 경우, 2030년 제주지역의 태양광과 풍력 발전의 출력제어량은 1,069GWh로, 출력제어 비율은 18.2%가 된다. 2023년 12월에 완공되는 제3연계선의 실시간 역송을 적용할 경우, 출력제어량은 474GWh, 출력제어비율은 8.1%로 감소한다. 제3연계선의 실시간 역송을 적용하지 않은 출력제어 전력으로 생산 가능한 그린수소의 생산량은 16,626톤이다. 이를 4,000원/kg으로 환산하면, 약 655억원의 가치를 갖는다. 그린수소의 생산은 제주지역 출력제어 문제를 해결할 수 있는 근본적인 대안이 될 수 있으며, 이를 위해서는 인센티브 제도 정비 등 정책적 장치 마련과 CFI 2030의 추가 보완계획 수립 검토가 필요하다. This study predicts the scale of output control of solar and wind power generation in Jeju from 2024 to 2030 under the CFI 2030 through step-by-step assumptions, and calculates the amount of green hydrogen that can be produced by utilizing output-controlled power. Assuming the CFI 2030s goal of introducing renewable energy generation facilities is achieved as planned from 2024, the power control amount for solar and wind power generation in Jeju in 2030 is projected to be 1,069GWh, with an output control ratio of 18.2%. If real-time reverse transmission is applied to the third interconnection line, scheduled for completion in December 2023, it is predicted that the output control amount will decrease to 474GWh, with an output control ratio of 8.1%. The amount of green hydrogen that can be produced with the output-controlled power without applying the real-time reverse transmission from the third connection line is 16,626 tons. When converted at 4,000 won/kg, this has an approximate value of 65.5 billion won. The production of green hydrogen can be a fundamental solution to Jejus output control challenges. To achieve this, it is necessary to establish policy devices such as the establishment of an incentive system and to consider establishing an additional complementary plan to CFI 2030.
