In this paper, we describe the approaches of shopping agents and directory services for online comparison shopping on the web, and propose an information indexing and retrieval system, named InfoEye, with a new method for automatic extraction of product information. The developed method is based on the knowledge about presentation of the product information on the Web. The method from the knowledge about presentation of the product information is derived from both the point that online stores display their products to customers in easy-to-browse ways and heuristics made of analyses of product information look-and-feel of domestic online stores. In indexing process, the method is applied to product information extraction from Hypertext Markup Language (HTML) documents collected by a mirroring robot from online stores. We have made InfoEye to a readily usable stage and transferred the technology to Webnara commercial shopping engine. The proposed system is a cutting-edge solution to help customers as a shopping expert by providing information about the reasonable price of a product from dozens of online stores, saving customers shopping time, giving information about new products, and comparing quality factors of products in a same category.

Intestinal duplication is a rare congenital anomaly. The diagnostic approach is difficult because of the differences in its location and clinical presentation. To evaluate the diagnostic as well as the therapeutic approaches in children, the medical records of 20 patients with intestinal duplications which had been operated upon from July 1980 to October 2002 were analyzed, retrospectively. The range of age was from 1 day to 11 years. The variables, such as age, sex, clinical presentation, diagnostic method, localization, anatomic type, treatment, complication, and combined anomalies were analyzed. Most of the cases were presented as incidental finding. The majority of the duplications except hindgut were cystic type. Treatment included segmental intestinal resection, excision of the lesion without intestinal resection, and septotomy. Seventy-five percent of the patients were detected before 1 year of age. The anatomic type of the lesion was closely related with its location. The cases of hindgut were almost always tubular type except 1 case. Clinical presentation was related to age, location, and anatomic type. There were no specific diagnostic methods. Perfect localization and application of appropriate operation are the most important requirements for successful treatment.

지금까지 질의 결과에 대한 프리젠테이션은 일반적으로 외부 툴이나 리포트 작성기를 통해 이루어지고 있는데, 프리젠테이션을 작성하는 방법이나 저장 방법 등이 표준화되어 있지 않기 때문에 다른 응용에서 질의 결과를 사용하는 데 많은 어려움이 따른다. 따라서 멀티미디어 데이터를 질의하는 질의어에서 표준화된 방법으로 프리젠테이션을 정의할 수 있는 방법이 필요하다. 본 논문에서는 W3C (World Wide Web Consortium) 의 멀티미디어 프리젠테이션 표준인 SMIL (Synchronized Multimedia Integration Language) 2.0을 기반으로 SQL을 확장하여 멀티미디어 데이터에 대한 사용자가 질의와 질의결과에 대한 프리젠테이션 작성를 원활히 할 수 있도록 한다.

Purpose: This study was to investigate adequate strategies of PBL in community health nursing for learning in the real community situation. Method: Data were collected in a PBL class of 14 third-year students who solved problems and assessed PBL in community health nursing related to visiting nursing and chronic diseases. Results: The students guessed situations diversely, chose learning issues widely and mapped the learning concepts specifically. In the assessment of the presentation, the peers of the same group gave the highest score $29.00{\pm}3.36$, the tutor lowest score $22.83{\pm}5.15$. In 5-point Likerts scale, the group dynamic was highest ($4.18{\pm}.61$) and the presentation was lowest ($3.59{\pm}.84$). Conclusion: The group needs to include students who have experiences in the practice at the health centers. The PBL class should be managed by the block system along with the conventional learning. Students needs to practice the self-directed learning and the presentation in a first semester and then PBL. The introduction of community health nursing begins with the conventional lecture and the programs on life circle and health centers through PBL in the comprehensive curriculums.

The purpose of this study was to examine how environmental education teachers think about environmental teaching materials of their use in primary and secondary schools. For this purpose, six primary and secondary school teachers were selected for focus group discussion on October 17th, 2005. The discussion of focus group was recorded both on video and audio tapes. Teachers' discussion could be analyzed in the perspectives of two big ideas, 'content selection' and 'content organization and presentation'. The big ideas were categorized into several areas: 1) The idea of 'content selection' was classified into 4 areas such as integration, difficulty level, locality, and timeliness, 2) The idea of 'content organization and presentation' was classified into 4 areas such as learning motivation, teaching and teaming strategy, evaluation method, application of teaching materials. This study provided meaningful ideas, which can be used in developing environmental education materials as well as effective teaching and teaming strategies for school environmental educators.

Background: 6-year College of Pharmacy curriculum had started in Korea, and the students in college of pharmacy are supposed to have student practice in the hospital pharmacy, community pharmacy, pharmaceutical company and administration to experience the role of pharmacists in advance. However, despite Korean Association of Pharmacy Education provided its own teaching plan, most Pharmacy Schools and the hospital pharmacy have difficulty in performing the desirable student practice program because they seldom experienced it. So, we reported the student practice program in the hospital pharmacy conducted by Yonsei University College of Pharmacy prior to the other numerous universities and the evaluation of survey on the student pharmacy practice program. Method: Severance Hospital, Gangnam Severance Hospital and National Health Insurance Service Ilsan Hospital took part in the student pharmacy practice program of Yonsei University. Students took 8-week pharmacy practice in Severance Hospital or Gangnam Severance Hospital plus 4-week pharmacy practice in National Health Insurance Service Ilsan Hospital. Also, students had once-a-week presentation class at school. A survey was conducted to evaluate the student practice program. Results: The presentation class was considerably helpful to share their own experiences at different practice sites in different hospitals, but there were some disadvantages that students could not experience the specific pharmacy practice site on the day of once-a-week presentation at school and so on. The results of the survey on the student practice program reported that students were satisfied with the overall practice program and presentation class at school. Also, they answered that the student practice program in the hospital pharmacy was significantly helpful for planning of the future career. Conclusion: Through the performance of the student practice program in Yonsei University, the adjustment of the student practice program in the hospital is planned to provide better experience of practice to the students and the results will be helpful for the student practice in the hospital of the other colleges of pharmacy.
