본 연구에서는 고영양 건강식품으로 주목받는 퀴노아를 섭취하는데 있어 다양한 활용방안을 모색하고자 발아와 열처리 가공을 통한 퀴노아의 이화학적 특성과 in vitro 생리활성을 조사하였다. 페루산 퀴노아를 사용하여 48시간 발아시켰을 때, 퀴노아의 일반성분(조단백, 조지방, 조회분 함량)은 발아에 따라 감소하였고 전분과 아밀로오즈 함량은 약간 증가하였다. 발아 후 α-amylase 활성은 48시간 동안 발아하는 동안 지속적으로 증가하였으며, 최종 48시간에서의 활성은 비발아한 원곡보다 약 2배가량 높은 활성을 나타냈다. 발아에 따라 퀴노아 분말의 색도는 L값이 증가하여 밝기가 밝아지며, 녹색도와 황색도가 감소하여 점차 색상이 옅어짐을 알 수 있었다. 발아한 퀴노아 분말을 신속점도측정계(RVA)로 그 특성을 분석한 결과 RVA 점도는 발아가 진행됨에 따라 점도가 감소하였는데 이는 발아에 따라 효소 활성도가 증가함에 의한 결과로 도출되었으며 in vitro 전분 가수분해율 역시 발아의 진행이 가수분해율의 향상을 초래하였다. 퀴노아의 총 페놀함량은 증류수로 추출할 때 수침시와 발아 24시간 까지는 미미하게 감소하였으나 발아 48시간 경과에서 증가하였고, 80% EtOH 추출시에는 일정하게 증가하였다. 퀴노아의 총 플라보노이드 함량은 추출용매와 상관없이 발아과정에 따라 일정하게 감소하였다. 항산화능 평가로써 DPPH 소거능은 두 용매에서 모두 발아하면서 감소하였으나, 아질산염 소거능에서는 80% EtOH 추출시에 점차 증가하는 것으로 나타났다. 퀴노아의 가열처리로 열탕(boiling)처리와 증자 후 배소(steaming/roasting)처리하는 두 가지 방법을 이용하였다. 퀴노아의 일반성분은 퀴노아를 boiling처리 하였을 때 조단백, 조지방이 약간 감소하였으나 steaming/roasting의 경우 함량에 차이가 없었다. 전분과 아밀로오즈 함량에서도 약간의 감소가 있었으나 전반적으로 유사하였다. 열처리 퀴노아 분말은 L값이 감소하여 밝기가 어두워지는 것과 녹색도와 황색도가 증가하여 색상이 짙어지는 것으로 나타났다. 열처리한 퀴노아의 WSI는 원곡에 비하여 증가한 반면, WAI는 열처리로 인하여 감소하였다. 열처리 퀴노아의 신속점도계(RVA) 점도가 매우 낮은 특성을 보였으며 in vitro 전분 가수분해율은 원곡에 비해 크게 증가하였다. 퀴노아의 총 페놀 함량은 증류수와 EtOH 용매 두 가지 모두 원곡에 비하여 가열처리에 의해 감소하는 것으로 나타났는데 원곡에서 각각 1.37, 1.08 mg/g에서 boiling은 0.93, 1.02 mg/g이었으며 steaming/roasting은 0.85, 0.89 mg/g으로 나타나 boiling 처리하였을 때 보다 steaming/roasting의 감소가 더욱 큰 편이었다. 또한 플라보노이드 함량에서도 역시 두 가지 용매 모두 열처리 가공시 감소하였고 원곡, boiling, steaming/roasting이 각각 0.76, 0.52, 0.42 mg/g 및 0.35, 0.18, 0.13 mg/g으로 나타나 가열처리 하였을 때 플라보노이드 함량의 감소를 확인할 수 있었다. DPPH 소거능은 에탄올 추출시 원곡 20.02%에 비하여 boiling은 15.25%, steaming/roasting은 12.35%로 나타나 열처리에 의하여 감소하는 것을 확인하였다. 그리고 아질산염 소거능에서는 증류수를 용매로 추출하였을 때 원곡 41.88%였지만 boiling은 34.55%, steaming/roasting은 31.75%로 나타나 열처리에 의하여 감소하는 것을 확인하였다.

The purpose of this study is to verify the effects of the post traumatic growth group counseling program carried out on the female sexual victims; if it effects on their emotional regulation, sexual violence attribution and post traumatic growth. In order to achieve such goal, this study carried out to investigate the effects of sexual violence victimization on the experiences of 20‘s sexual violence victims who expressed their willingness to participate in the research by publicizing offline and online in the university counseling center and gender equality center in Busan. Finally, the selected 12 women were divided into two groups. The 6 groups assigned to an experimental and 6 groups to a control group. The Posttraumatic Growth group counseling program was carried out for the experimental group for 10 times each 120 mins, where as not a single treatment was applied to the control group. In order to verify the effectiveness of the program, pre-post test for the emotional regulation, sexual violence attribution and posttraumatic growth. were carried out for both control group and experimental group. And by using SPSS / WIN 24 statistical programs, the mean and standard deviation for each scale were calculated. To verify the difference between the experimental and the control group, the analysis of covariance (ANCOVA) was performed putting the pre-test scores as a covariate. The results of this study are as follows. First, the emotional regulation for the experimental group after participating the Post traumatic Growth group counselling program was much increased than the control group not participated in the program. Second, the self-attribution for the experimental group after participating the Posttraumatic Growth group counselling program was much reduced than the control group not participated in the program and the other-attribution for the experimental group was much increased than the control group. Third, the post traumatic growth for the experimental group after participating in the Post traumatic Growth group counseling program was much increased than the control group not participated in the program. Considering to the results of the study, it was clear that the program is effective in lowering of emotional regulation, sexual violence attribution and post traumatic growth. Finally, limitation to the current study and recommendations for future research are discussed.

On the Performance of Secure XML Broadcasting

고혜경 고려대학교 대학원 2008 국내박사

XML (eXtensible Markup Language) has emerged as a prevalent standard for document representation and exchange on the Web. XML is moving toward the center of the database applications and Web services. Many companies and academic researchers are actively searching for the firm standards while preserving its flexibility. The most important issue arisen through these processes is XML security. Web-based environments require revisiting the traditional way of performing access control. Although traditional access control mechanisms have been used to filter returned documents in the context of a user-demand information dissemination mode, secure broadcasting of web documents is becoming increasingly important. Secure broadcasting of web documents is becoming a crucial requirement for many web-based applications. Under the broadcast document dissemination strategy, a web document source periodically broadcasts (portions of) its documents to a potentially large community of subjects, without the need for explicit request. By secure broadcasting, we mean that the delivery of information to subjects must obey the access control policies of the document source. Since different subjects may have the right to access different portions of the same document, enforcing secure broadcasting requires to efficiently manage a large number of different physical views of the requested document and sending them to the proper subjects. Traditional access control mechanisms that have been adapted for XML documents, however, do not address the performance issues inherent in access control. In this thesis, we present an approach to secure broadcasting of web documents, based on the use of encryption techniques. Two labeling schemes are proposed to support rapid reconstruction of decrypted XML document in the context of a well-known method, called XML pool encryption. In order to search for the proper location of encrypted nodes in an XML document, the effective and efficient identification of the relationship among nodes in presented. The first labeling scheme called IPL (Improved Prefix Labeling), which supports the speedy inference of structure information in all locations of the document. In the IPL, labels of nodes in an XML document contain information regarding their parent and ancestor nodes as succeeding portions of the parent node label. The binary representation of IPL is also investigated to reduce the overhead, i.e., by transforming the string into an integer for label comparison. However, when it comes to encrypting (portions of) and XML tree, the IPL cannot label a partial tree, thus information leakage exists. When the encrypted nodes remove from the tree, an adversary can guess the location of encrypted node in terms of the labeling information. Because the difference between the right and left value of labeling is 1. In order to solve this problem, we propose an enhanced labeling scheme, named IBSL (Improved Binary String Labeling) which takes advantages of lexicographic order of binary strings. The labeling separates the public node and the secure node in IBSL. Consequently, IBSL can hide the label values which are assigned to secure nodes. In the experimental results, the proposed labeling schemes are efficient in searching for the location of decrypted information.

Traditionally virtual reality system has been modeled and rendered using 3D computer graphics technique. But, as scenes are getting complicated, it takes more time to render. Thus navigating in virtual environment gets slower. As a result, because quality and complexity of rendered images is limited, constructing realistic virtual environment is hard to achieve. Or, expensive and special purpose rendering hardware for real-time navigation is requested. To solve those problems, visibility culling is processed, or LOD technique, which uses real geometic model for objects that are near and represents objects far away simply, is used. Or faster algorithm for dealing complex scenes can be used. Or image-based representation is used. Among those, image-based representation, which is actively studied nowadays, is a method that make things faster using images rather than geometric models, which requires much more times. This paper deals with realtime virtual environment navigation using environmental map among many image-based methods. Because environmental map contains information for all direction from a view point, no image generation procedure is required for every scene. It enables high-quality, simple, and low-price realtime navigation in virtual environment, because it uses photographs. However, environmental map has a problem, navigation in a static view point. Exsiting systems, like QuickTime VR, incorporate many environmental maps, and jumping from and to those maps is used for emulating navigation. But there was no visional continuity. In this paper, connected images are matched in preprocessing step, natural and continuous navigation in virtual environment is successfully done by interpolating the environmental maps. However the suggested method has a few things to be solved. First, interpolation is processed on the assumption that there is no objects in the front. If there is an object in front of a view point, additional process for detaching the objects would be necessary. Second, only cube mesh is used. So more mesh type would be needed for various scenes. Third, only movement in front is possible when you move between cylinders. More study for seeing left and right side while you are moving between cylinders are necessary.

본 연구는 ‘전설의 지리적 요소를 활용한 스토리텔링 수업 기법’을 지리 교육에 활용할 수 있는 방안과 자료를 개발해 제시하고 실제 지리수업에 활용해 봄으로써 지리교육에서 ‘전설’과 ‘스토리텔링’ 활용 교육의 효과를 알아보는데 있다. 이를 위해 본 연구에서는 수업 과정을 3단계로 구분하여 진행하였다. 첫 번째 단계는 ‘전설과 지리교과는 연관성이 없다는 인식 전환하기’ 단계로 지리적 요소를 포함하고 있는 전설은 단순 스토리가 아니라 실제로 증명할 수 있음을 밝혀 학습 자료로 재구성하였다. 이 자료를 토대로 두 번째 단계인 ‘지리적 요소를 찾는 도구로 전설 활용하기’의 주제 수업을 진행하였다. 세 번째 단계는 ‘지형을 활용해 스토리 창작하기’ 단계로 지리적 요소를 포함한 스토리를 학생이 스스로 창작하게 하였다. 세 단계의 수업을 진행한 후 수업에 참여한 100명의 학생을 대상으로 심층 면담 및 설문조사를 통해 수업의 효과에 대해 알아보았다. 그 결과 ‘전설의 지리적 요소를 활용한 스토리텔링’ 지리 수업은 학생들로 하여금 ‘창의성’을 발휘하게 하며 과정이 ‘참신하다’는 인식을 심어주고, 과제 완성을 통하여 ‘성취감’을 주는 수업임을 확인하였다. 이를 통해 ‘전설의 지리적 요소를 활용한 스토리텔링’ 지리 수업은 학생의 지리 과목에 대한 흥미를 유발함과 동시에 사고를 확장하는 데 긍정적인 수업이라는 결론을 얻었다. The purpose of this study was to investigate the effectiveness of storytelling techniques and geographical contents found in legends in geography education by developing ways to utilize such techniques and related teaching/learning materials and implementing them in actual classes. To this end, class procedures were divided in three stages in this study. The first stage was for changing the recognition that legends have nothing to do with geography. Students were shown that geographical contents in legends, often regarded as mere imaginary stories, could be verified as facts, which were reconstructed as teaching-learning materials. In the second stage, the focus of class activities fell on utilizing legends as tools for finding geographical contents. In the following stage, namely ‘Story Creating Stage Using Geographical Features’, students were encouraged to make their own stories containing geographical contents. After the three-staged classes, an in-depth interview and survey was conducted with one hundred students who took part in the project as to the effectiveness of the process. The results showed that the storytelling classes were effective in stimulating students’ creativity, making them feel sense of task-accomplishment as well as becoming interested in the class process itself. Therefore, it can be said that storytelling lessons using geographical contents found in legends are positive in arousing students’ interest in geography and enlarging their thinking.
