<P>Reactive oxygen species (ROS), generated by ionizing radiation, has been implicated in its effect on living tissues. We confirmed the changes in the oxidative stress markers upon irradiation. We characterized the changes in the proteome profile in rat liver after administering irradiation, and the affected proteins were identified by MALDI-TOF-MS and ESI-MS/MS. The identified proteins represent diverse sets of proteins participating in the cellular metabolism. Our results demonstrated that proteomics analysis is a useful method for characterization of a global proteome change caused by ionizing radiation to unravel the molecular mechanisms involved in the cellular responses to ionizing radiation.</P>

TALP-35 purified from human term placenta is known to increase microtubule polymerization and stabilize the polymerized microtubule. To examine the effect of TALP-35 on immune system this study was performed. MTT assay was performed to investigate the effect of TALP-35 on the proliferation of RAW264.7 cells. TALP-35 dose dependently suppress the proliferation of RAW264.7 cells at high concentration (above 1 μM) in unstimulated cells, in case of 10 μM TALP-35 treated cells the suppression was 25% but in stimulated cells it was only 15%. Cosedimentation assay was carried out to investigate whether TALP-35 can bind to tubulin of RAW264.7, monocyte/macrophage lineage of mouse, and polymerize it. TALP-35 polymerize the tubulin of RAW264.7 cells and sedimented in dose-dependent manner. To investigate the effect of TALP-35 on the expression of iNOS protein western blotting was performed. The expression level of iNOS was decreased dose dependently in high concentration of TALP-35 treatment. To examine the activity of iNOS, secreted NO was determined by method based on Griess reaction. Interferon-γ and LPS-stimulated production of NO from RAW264.7 cells was decreased dose dependently above 0.1 μM concentration of TALP-35 and 50% is decreased at 10μM of it. This study shows TALP-35 can control cytokine induced-iNOS expression therefore it might control inflammatory diseases.

Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

The purpose of this study was to examine the effect of two different intensity of continuous exercise on magnitude of excess post-exercise oxygen consumption(EPOC), energy consumption following a 20min treadmill exercise. The subjects of this study were eight super-obesity in middle school students who were above 13 years old. subjects participated in two different exercise intensity to measure respiratory gas, blood lactate concentration and eardrum temperature. The results of this study were as follows: 1. The Energy consumption of the high intensity (80% VO₂ max) exercise group (264.68 35.60cal) was greater than that of the low intensity (50%) exercise group(172.01 20.39 Cal)(p<.001). 2. The EPOC of the high intensity exercise group (22.36+ 6.82Cal ) was greater than that of the low intensity exercise group(15.39+5.27 Cal)(p<.001). 3. The EPOC duration of th high intensity exercise group(28.36=3.56min) was longer than that of the low intensity exercise group(17.23+1.25min)(p<.001) 4. The blood lactate concentration, respiratory exchange ratio and temperature of the high intensity exercise group were greater than those of the low intensity exercise group(p<.05,p<.01). EPOC and duration were increase with 80%VO₂max, 80% VO₂max as intensity exercise got higher this also showed that it had something to do with lactate concentration in blood and increase of body temperature in the conclusion. We considered that there was a difference in using methods of energy, as there was a similar difference in RER. We though this following with oxygen consumption after exercise, we could clarify that high intensity exercise was better than lower intensity exercise in sametime for those who are obese especially adolescents to maintain their weights on the aspect of effect.

2007년 국내 고등교육기관에서 수학하고 있는 외국인 유학생의 수는 4만 9천여명을 넘어섰다. 이러한 분위기에서 외국인 유학생들에 관한 논의들이 몇 가지 측면에서 진행되고 있다. 그러나 대체로 유학생의 유치를 위한 전략 또는 유학생의 학업적 적응, 문화적 적응과 같은 단편적인 측면에서의 적응만을 조사한 연구들이 대부분이었다. 이러한 분위기에서 외국인 유학생들에 관한 논의들이 몇 가지 측면에서 진행되고 있다. 그러나 대체로 유학생의 유치를 위한 전략 또는 유학생의 학업적 적응, 문화적 적응과 같은 단편적인 측면에서의 적응만을 조사한 연구들이 대부분이었다. 이를 바탕으로 진행한 연구의 결과를 요약하면 다음과 같다. 첫째, 외국인 유학생의 국내 공간적 분포 특성은 유학생 유입 초기단계에는 수도권에 압도적으로 많이 이루였으나, 그 후 수도권의 집중현상은 점차 완화되고 있다. 둘째, 설문조사 에서는 외국인 유학생의 국제이주 원인으로 거시적 차원의 배출-흡인 요소 보다는 미시적 차원의 배출-흡인요소가 더 많은 영향을 주는 것으로 나타났다. 셋째, 외국인 유학생의 지역사회 적응에 필요한 각 요소별 적응은 개인별로 상이하게 나타난 다. 특히 한국어 구사능력이 높고 한국인 친구의 수가 많을 수록 대학 및 지역사회에서 적응하기가 용이한 것으로 조사되었다. 또한 유학생활과 지역사회에서의 적응정도가 높을수록 지역사회에서 느끼는 정체성도 높게 나타났다. 이를 통해 지역사 회 주민으로서 정체성이 높게 형성된 외국인 유학생에게 지역사회의 발전에 기여하는 역할을 기대해 볼 수 있다. The number of foreign students studying in domestic higher educational institutes in South Korea exceeded 49,000 in 2007. One reason to pay attention to the rapid expansion of foreign students is that the impact of them on local community also becomes greater as their proportion increases. Under this circumstance, considerable discussions concerning them from several aspects have been undertaken. However, most of researches are limited to partial aspects of either strategy to attract foreign students or their academic and cultural adaptation. Therefore, this study selects universities in Daegu and Gyeongbuk area and intends to analyze the migration causes, to figure out the characteristics of their spatial distribution, to examine their adaptational patterns and finally to suggest some measures for them. The study results based on these are summarized as follows: Firstly, as for foreign students’ spatial distribution, Seoul and its surrounding area was where foreign students are most frequently located at the early stage of their migration. Secondly, the questionnaire survey results show that the macro level of push-out/pull-in factors has a greater impact on foreign students’ migration than the micro level of them. Thirdly, the adaptation patterns across each dimension show individual differences. In particular, the foreign students who have a higher Korean language ability and more Korean friends show a better adaptation to university and local community. In addition, the results show that those with higher adaptation level to the life of study abroad and local community have a higher level of perceived identity as a member of their local community, through which a contribution of those foreign students with higher identity as a community member to the development of the local community may be anticipated.

최대/최소 경계 스키마 추출 기법을 이용한 XML 문서의 DTD 추출

박경현,최은선,이종연,박정석,류근호 충북대학교 컴퓨터정보통신 연구소 2000 컴퓨터정보통신연구 Vol.8 No.2

XML이 인터넷상의 데이터 교환의 표준으로 대두되면서 데이터 모델이나 플랫폼에 관계없이 데이터의 전송이 가능하게 되었다. 특히 데이터 중심의 XML 문서의 경우 전송시의 부하를 줄이기 위해 DTD없이 전송되는 경우가 일반적이다. 그러한 이유로 전송받은 XML 데이터의 저장 효율을 높이고 질의를 최적화하며 사용자에게 편의성을 제공해주기 위해서는 XML 데이터로부터 DTD 추출이 필수적으로 요구된다. 이 논문에서는 이러한 DTD를 추출하기 위해 반구조적 데이터의 스키마 추출 기법을 적용한다. 특히, 반구조적 데이터의 최소 경계 스키마를 추출하는데 데이터로그를 이용하는 기존의 방법보다 효율적인 방법인 시뮬레이션을 적용함으로써 보다 향상된 DTD 추출 기법을 제시한다. XML makes it possible for data to be exchanged regardless of the data model in which it is represented or the platform on which it is stored, serving as a standard for data exchange format on the internet. Especially, It is natural to send XML data without DTD on the internet when XML is data-centric XML. Therefore it is needed to extract DTD to store XML data efficiently, to optimize queries, and to help users browse XML data. In this paper, Techniques for upper/lower bound schema extraction are applied to extract DTD from XML data. Especially we propose an efficient technique for extracting DTD by using simulation which is better than datalog as a lower bound schema extraction method.
