This study developed teaching-learning materials for 10 class periods that applies design thinking process for the units of 'sustainable consumption' of home economic subject, and examined the learning experience of students in the class. After the classes, reflection journals and in-depth interviews from 276 male and female students in ten classes were analyzed. The main results are as follows: The five steps of the design thinking process of the Stanford University d-School were applied to develop teaching-learning materials for the 'Sustainable Consumption Practice Book Creation Project'. Students' positive learning experience was evidenced through sustainable consumption classes that applied design thinking. The students were able to reflect through the experience of sympathizing with the real problem, and experienced an improvement in problem-solving ability through the process of idea construction and prototyping. Students expressed difficulties in reaching consensus among the members, and in devising ideas and implementing prototypes. Based on the learning experience of students this study, it is suggested that home economic teachers further develop and implement classes of various topics to which design thinking process is applied. A future study may need to verify the effectiveness of home economic classes to which design thinking is applied.

Regarding countless network disorders or invasions happening nowadays from 2014 until 2015, illegal access intended to attack through the communication line provided by ISP (Internet Service Provider) appears to be the source of the problem. As a defensive way to prevent such network-based attacks, not only stabilization structures for network communication but various policies as well as physical security devices and solutions corresponding to those have been realized and established. Therefore, now is the time to gain foundational research data to secure network security sections by producing logical area on communication bandwidth or such, suggest tasks to expand the communication line which is another research topic in the network security market, and recognize the fact that the active communication bandwidth linkage paradigm using network communication bandwidth is needed as one of the areas that can realize physical security. Additionally, it is necessary to limit the data in the forms of organizing visible security structures into a certain range of physical information by re-dividing communication capacity being currently provided by telecommunicators into subdivided organizational areas and applying the logical virtualization of communication capacity in each of the areas divided. By proposing a network security section based on a logical field application in place of the existing physical structure, basic data that designs a stable physical network communication structure will be provided.

Nowadays, recognizing human activities is an important subject; it is exploited widely and applied to many fields in real-life, especially in health care and context aware application. Research achievements are mainly focused on activities of daily living which are useful for suggesting advises to health care applications. Falling event is one of the biggest risks to the health and well-being of the elderly especially in independent living because falling accidents may be caused from heart attack. Recognizing this activity still remains in difficult research area. Many systems equipped wearable sensors have been proposed but they are not useful if users forget to wear the clothes or lack ability to adapt themselves to mobile systems without specific wearable sensors. In this paper, we develop a novel method based on analyzing the change of acceleration, orientation when the fall occurs and measure their similarity to featured fall patterns. In this study, we recruit five volunteers in our experiment including various fall categories. The results are effective for recognizing fall activity. Our system is implemented on G1 smart phone which are already plugged accelerometer and orientation sensors. The popular phone is used to get data from accelerometer and results showthe feasibility of our method and significant contribution to fall detection.

사람은 누구나 잭이나 문서를 읽을 때 중요한 부분에 강조, 해설, 설명을 하기 위해서 표시를 하거나 글을 입력한다. 이와 같이 원본문서에 추가되는 부가 정보를 Annotation이라고 한다[6][7]. Annotation을 이용하면 차후에 원본문서를 재창조하거나 다른 사람이 원본문서를 참조할 경우 과중한 정보의 양을 극복할 수 있으므로[4], 원본문서의 이해도를 향상시킬 수 있다. 따라서, Annotation은 한번 사용하고 그치는 정보가 아닌 재사용할 수 있는 점보임을 의미한다[1,2,3]. 이러한 Annotation 기능을 웹 문서에 적용하게 되면 종이문서에서 얻을 수 있는 장점뿐만 아니라 웹 환경의 특징인 공유[5], 검색[4], 재편집 등의 기능이 가능하다. 이와 관련한 많은 연구가 진행중에 있다. 그러나, 기존의 Annotation 연구는 Anchor 입력된 다수의 Annotation이 무의미한 출력 순서로 제공되고 있으며, 또한 Anchor에 입력된 Annotation의 출력으로 인해 문서 구조가 변경되거나, 가려지는 등의 문제점으로 사용자들이 쉽게 사용 및 이해할 수 있는 Annotation 출력 인터페이스에 대한 연구가 부족한 실정이다. 따라서, 본 논문에서는 Anchor에 입력된 다수의 Annotation들 간의 의미적 순서를 부여하여 보다 적절한 Annotation에 대한 우선 접근이 가능하도록 계층적인 Annotation 우선처리 기법을 제안하고, Annotation 출력으로 인한 문서 변경 문제를 해결하기 위한 유동적인 Annotation 표현 기법을 제안한다. 또한 Annotation이 문서에 부가된 부가정보의 역할을 뿐만 아니라, 다양한 활용이 가능하도록 XML 표준에 기반한 저장 구조를 지원하며, 원본문서와 분리하여 저장한다.속도를 개선시켰고, 국소적인 변형이 있는 패턴과 특징의 수가 다른 패턴의 경우에도 좋은 인식률을 얻었다.r interferon alfa concentrated solution can be established according to the monograph of EP suggesting the revision of Minimum requirements for biological productss of e-procurement, e-placement, e-payment are also investigated.. monocytogenes, E. coli 및 S. enteritidis에 대한 키토산의 최소저해농도는 각각 0.1461 mg/mL, 0.2419 mg/mL, 0.0980 mg/mL 및 0.0490 mg/mL로 측정되었다. 또한 2%(v/v) 초산 자체의 최소저해농도를 측정한 결과, B. cereus, L. mosocytogenes, E. eoli에 대해서는 control과 비교시 유의적인 항균효과는 나타나지 않았다. 반면에 S. enteritidis의 경우는 배양시간 4시간까지는 항균활성을 나타내었지만, 8시간 이후부터는 S. enteritidis의 성장이 control 보다 높아져 배양시간 20시간에서는 control 보다 약 2배 이상 균주의 성장을 촉진시켰다.차에 따른 개별화 학습을 가능하게 할 뿐만 아니라 능동적인 참여를 유도하여 학습효율을 높일 수 있을 것으로 기대된다.향은 패션마케팅의 정의와 적용범위를 축소시킬 수 있는 위험을 내재한 것으로 보여진다. 그런가 하면, 많이 다루어진 주제라 할지라도 개념이나 용어가 통일되지 않고 사용되며 검증되어 통용되는 측정도구의 부재로 인하여 연구결과의 축적이 미비한 상태이다. 따라서, 이에 대한 재고와 새로운 방향

This study focuses on Ko woo-young (1939-2005), a Korean representative cartoonist. I analyzed his work Nolbudyeon (1988), which is a retelling of Heungbu and Nolbu, a traditional Korean story. I consider Ko woo-young a creative observer who has popularized his perspective in modern society. His work is a good example of how a traditional folktale can be made relevant in modern society. I used three methods of adaptation to differentiate Nolbudyeon from Heungbu story: construction of events, characterizing, and space-time background. First, to aid character development, Nolbudyeon includes a prologue that focuses on conflicts between brothers with different personalities. At the same time, the ambiguous ending could be a response to Heungbu story, which has a didactic theme. Second, I found that the new characters, Nolsun and Yeonsaengwon, enhanced the differences between Heungbu and Nolbu by playing the role of mediators. Also, in Nolbudyeon, both Heungbu and Nolbu had positive as well as negative elements, in contrast with the original story's traditional point of view on good and evil. Finally, by exploring the space-time of Nolbudyeon, we can see that its world is combined with the contemporary world. In other words, Nolbu and Heungbu, though outwardly traditional, have a modern outlook. Therefore, readers can recognize that Nolbudyeon is a metaphor for modern life rather than just an old story.

We face problems from excessive information served with websites in this rapidly changing information era. We find little information useful and much useless and spend a lot of time to select information needed. Many websites including search engines use web crawling in order to make data updated. Web crawling is usually used to generate copies of all the pages of visited sites. Search engines index the pages for faster searching. With regard to data collection for wholesale and order information changing in realtime, the keyword-oriented web data collection is not adequate. The alternative for selective collection of web information in realtime has not been suggested. In this paper, we propose a method of collecting information of restricted web sites by using Web crawling distributed monitoring system (R-WCMS) and estimating collection time through detailed analysis of data and storing them in parallel system. Experimental results show that web site information retrieval is applied to the proposed model, reducing the time of 15-17%.
