김성림,권준희 대한전자공학회 2006 電子工學會論文誌 IE (Industry electronics) Vol.43 No.1

According to the growth of wireless networks, and the spread of mobile devices, the provision of recommender services to help consumers find items to purchase with the use of the suited contexts is an important issue in mobile commerce. In this paper, we propose a proactive mobile commerce service that enables a consumer to obtain relevant information efficiently by using differentiated recommendation in context-aware environment. This paper describes the recommendation method and presents grocery shopping application prototype that implement the method. Several experiments are performed and the results verify that the proposed method's recommendation performance is better than other existing methods. 무선 기술의 빠른 발달과 이동통신 사용자의 급증으로 모바일 커머스에서 각 소비자들에게 컨텍스트에 맞게 효과적으로 정보를 권유하는 서비스의 필요성이 점차 부각되고 있다. 본 논문에서는 컨텍스트 인식환경에서 모바일 커머스 서비스를 위한 차별화된 프로액티브 권유 기법을 제안한다. 제안한 기법에서는 컨텍스트에 따라 한번에 모든 정보를 권유하지 않고 레벨별로 차별화하여 프로액티브하게 권유하고, 소비자의 패턴과 프리패칭 기법을 사용함으로써 효율적인 권유 서비스가 가능하다. 이를 위해 제안된 기법을 설명하고 이를 모바일 커머스 어플리케이션 프로토타입에 적용해본다. 또한, 실험을 통해 기존 기법보다 제안된 기법이 우수함을 보인다.

In ubiquitous environment, information retrieval using collaborative filtering is a popular technique for reducing information overload. Collaborative filtering systems can produce personal recommendations by computing the similarity between your preference and the one of other people. We integrate the collaboration filtering method and context-aware information retrieval method. The proposed method enables to find some relevant information to specific user’s contexts. It aims to makes more effective information retrieval to the users. The proposed method is conceptually comprised of two main tasks. The first task is to tag context tags by automatic tagging technique. The second task is to recommend items for each user’s contexts integrating collaborative filtering and information retrieval. We describe a new integration method algorithm and then present a u-commerce application prototype.

The context-aware environment focuses on recognizing the context and physical entities. For this reason, there has been an increasement in research of context-aware computing environment. Ontology-based context models are widely used in ubiquitous environment because of context sharing and reusing. In this paper, we propose a proactive retrieval method using ontology in context-aware environment. The method use a concept level of hierarchical concept tree in ontology for more efficient retrieval. This paper describes the proactive retrieval method and ontology model. Several experiments are performed and the results verify that the proposed method's efficiency is better than other existing methods. 상황 인식 환경에서는 물리적인 환경, 상황 등을 시스템이 인식하고 이를 기반으로 사용자와의 상호작용을 지원하는 상황 인식 기술이 중요한 요소로 자리잡고 있다. 온톨로지 기반의 상황 정보 모델은 상황정보의 공유와 재사용의 이점을 제공하기 때문에 최근 널리 사용되고 있다. 본 논문에서는 상황 인식 환경에서 온톨로지를 이용한 새로운 프로액티브 검색 기법을 제안한다. 제안된 기법은 온톨로지의 계층적 개념 트리를 이용하여 사용자의 상황에 맞는 정보의 개념 수준을 결정함으로써 보다 효율적인 검색이 가능하다. 이를 위해 제안된 기법을 설명하고, 실험을 통해 기존 기법보다 제안 기법이 우수함을 보인다.

The purpose of this study is to examine the structure of understanding in the classroom. This paper has the preknowledge on understanding of Gadamer's ontological hermeneutics. According to Gadamer. understanding is the mode of being. It has the linguistic charcarter and historicity of understanding that are fundamental aspects of understanding. While Gallaghar agrees with Gadamer's position. he reasserts the essential connections of interpretation and education within the contemporary of hermeneutics. Especially, Gallagher notes the interchange of interpretation in teacher. pedagogical presentation. student and subject matter in the classroom. This paper accepts his analysis and critically reinterprets the structure of understanding in the classroom. The conclusion of this study are the followings. First, the educational understanding requires the presupposition that teachers and students participates in educational context. Second, it is able to create possibilities that goes beyond the intellectual genius on either teachers or students. Third, it makes the makes the students participate in the productive process of transformation. Finally, it is the structure of experience that the results of a dialectical interplay operating under the hermeneutical constrains of language and tradition.

Objective : DREZotomy is effective for the treatment of deafferentation pain as a consequence of root avulsion, postparaplegic pain, posttraumatic syrinx, postherpetic neuralgia, spinal cord injury, and peripheral nerve injury. We performed microsurgical DREZotomy to the patients with deafferentation pain and relieved pain without any serious complication. The purpose of this study is to evaluate the usefulness of the microsurgical DREZotomy for deafferentation pain. Methods : We evaluated 4 patients with deafferntation pain who were intractable to medical therapy. Two of them were brachial plexus injury with root avulsion owing to trauma, one was axillary metastasis of the squamous cell carcinoma of the left forearm, and the last was anesthesia dolorosa after surgical treatment(MVD and rhizotomy) of trigeminal neuralgia. Preoperative evaluation was based on the neurologic examination, radiologic imaging, and electrophysiological study. In the case of anesthesia dolorosa, we produced two parallel lesions in cephalocaudal direction, 2mm in distance, from the C2 dorsal rootlet to the 5mm superior to the obex including nucleus caudalis, after suboccipital craniectomy and C1-2 laminectomy, with use of microelectrode. In the others, we confirmed lesion site with identification of the nerve root after hemilaminectomy. We performed arachnoid dissection along the posterolateral sulcus and made lesion with microsurgical knife and microelectrocoagulation, 2mm in depth, 2mm in distance, to the direction of 30-45 degrees in the medial portion of the Lissauer's tract and the most dorsal layers of the posterior horn at the one root level above and below the lesion. Results : Compared with preoperative state, microsurgical DREZotomy significantly diminished dosage of the drugs and relieved pain meaningfully. One patient showed tansient ipsilateral ataxia, but recovered soon. There was not any serious complication. Conclusion : It may be concluded that microsurgical DREZotomy is very useful and safe therapeutic modality for deafferentation pain, especially segmentally distributed intermittent or evoke pain. Complete preoperative evaluation and proper selection of the patients and lesion making device are needed to improve the result.

경막하 수종으로 오인된 중두개와 지주막 낭종을 동반한 대뇌궁륭부 지주막 낭종 - 증 례 보 고 -

Arachnoid cysts are defined as duplicated arachnoids and their splitting with congenital, intra-arachnoid, and leptomeningeal malformations. They are most commonly located in the middle cranial fossa followed by suprasellar and quadrigeminal cisterns, posterior fossa, and very rare in cerebral convexities. They are often ruptured by trauma or spontaneously and cause subdural hygroma or subdural hematoma. Authors report a case of a 32-year-old woman with a convexity arachnoid cyst mimicking subdural hygroma associated with a separate middle fossa arachnoid cyst. Preoperatively, the convexity arachnoid cyst was misinterpreted as subdural hygroma resulted from a ruptured middle fossa cyst. The patient underwent craniotomy and cyst fenestration into the basal cistern. Two separate arachnoid cysts were found in the cerebral convexity and middle cranial fossa during the operation. Finally, cysts were resolved and she was discharged without any complication.

XML documents, which are becoming new standard for expressing and exchanging data in the Internet, don't have defined schema. It is not adequate to directly apply XML documents to the existing SQL or OQL. Research on how to extract Schema for XML documents and query language is going on actively. For users' query, the results could be too tony or too less. It Is important to give the users adequate results. This paper suggests the way to extract many levelized schema according to the frequency of element occurrence in XML documents. The Schema can be reduced or extended to correspond to the users' query more flexibly. 인터넷상에서 데이터를 표현하고 교환하는 새로운 표준으로 등장하는 XML 문서는 정해진 스키마를 가지고 있지 않다. XML 문서를 기존의 SQL이나 OQL에 바로 적용하기에는 부적합하여 이러한 XML 문서에 대해 스키마를 추출하는 방법과 질의어에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 XML문서에 대해 엘리먼트 정보를 이용하여 스키마를 추출하고, 추출된 스키마를 바탕으로 데이터 빈도수에 따라 새로운 여러 단계의 스키마를 추출하는 방법을 제시하고 실험한다.

Teratoid Wilms’tumor is a rare renal tumor. Fourteen cases have been reported. A 14- month-old girl was presented to us. She had a right renal mass which was diagnosed as a Wilms’tumor in another hospital. She had been treated with chemotherapy but failed to respond to it. The nephrectomy specimen revealed an encapsulated mass of which the cut surface was solid, firm, gray to yellow tan. Microscopically, the stromal elements were predominant, especially comparing with few blastemal element, but the degree of heterologous differentiation was sufficient to warrant the diagnosis of teratoid Wilms’tumor.
