Purpose: This study was to test the effectiveness of Web-based multimedia contents for Physical Examination and Health Assessment on learning achievement. Method: Multimedia contents based on Jung's teaching and learning structure model were used to enhance learning achievement. Learning achievement was measured by the knowledge of Physical Examination and Health Assessment. The participants of this study were students in a BSN and RN-BSN program in a university located in Seoul. 59 students in the experimental group received lectures using web-based multimedia contents and 75 students in the control group received regular lectures. Results: The mean score of the degree of educational achievement in the experimental group(mean=31.09) was significantly higher than in the control group(mean=25.55)(t=-3.883, p=.000). Conclusion: These web-based multimedia contents were found to maximizethe effectiveness of the teaching process when used as a teaching aid, and yet kept the strength of a face to face teaching learning method. This program is recommended as part of a main text, vital teaching aid or cyber lecture materials in nursing schools and in health care educational institutions.

This study proposes a collaboration system framework on the web service in a supply chain to implement an efficient virtual supply chain and improve an ability to fulfill received orders over a supply chain. The system based on the framework proposed in this paper plays an important role for automatic order negotiation and placing/receiving an order noticed in web service by the main system. Furthermore, it can evaluate the fulfillment of received orders over a supply chain by using the transaction results from hierarchically related vendors and establish efficient manufacturing plans. In a word, this system is the automated system for creating manufacturing plans, placing and receiving orders. A little more important main function of this system is that it has a dynamic evaluation capability about fulfillment with received orders over a supply chain, and improves the evaluation method of fulfillment ability with received orders with related to direct dealing vendors, which is a main problem in existing system. As a result, this system is able to reduce the work load of the sales and purchasing materials, production control division, to manage accurate inventory promptly, to maintain the optimal inventory level by analyzing the information of fulfillment ability with received orders, and to enhance the level of service for customers.

In this paper, we propose an authoring methodology of differentiated instruction-learning materials in mathematics course using MathML and XSLT, and give utilizing suggestions of these materials as differentiated textbook and individual learning. Incorporating MathML into instruction-learning materials, there are many advantages such that view of the materials in web browser is improved since mathematical expressions are compatible with text, and an expression can be modified in more convenient way since the expression is represented in text format not an image. In authoring of differentiated materials, the author provides one document for various levels of students. Then, each level of materials is generated from the document via XSLT transformation. This enables author-driven progress control rather than student-driven which does in previous approaches, since students don't need to select components of the material.

Purpose: The first web space of the foot has a similar thickness and skin texture of the pulp of the fingers. Moreover, it has a reliable blood vessel and sensory nerve. The purpose of this study was to evaluate the clinical results of the first web space free flap to reconstruct the pulp of fingers. Materials and Methods: Authors have performed 23 cases of first web space free flap to reconstruct the pulp defect of the fingers between June 2004 and May 2009. The age of the patients ranged from 20 years old to 55 years old. The size of the flap ranged from $1{\times}1.5cm$ to $8.5{\times}2.5cm$. The mean flap area was 5.4 cm2. In 4 cases, we elevated the flap including lateral aspect of the big toe and medial aspect of the second toe. And then we made an artificial syndactyly to reconstruct the pulps on two fingers at the same time. In all cases, we performed 1 digital artery and 1 dorsal vein anastomosis. Every donor site that had a small defect healed spontaneously without any additional operations to cover it. Results: Of this type of surgery 21 flaps (91.3%) survived, 2 flaps (8.7%) failed. There was no severe complication in the donor sites. There was no walking disturbance due to the skin defect of the donor site. The static 2 point discrimination in 11 cases that we could check ranged from 3 mm to 15 mm. Conclusion: The authors believe that the first web space free flap of the foot is a good option for the reconstruction of the pulp of the fingers and it has a minimal donor site morbidity.

21세기 정보시대에는 학생들이 자유로운 정보 탐색이나 수집과 같은 활동을 통하여 자신의 학습 활동을 진행시켜 나갈 수 있는 능력을 길러주는 교육이 필요하다. 이러한 자기 주도적 학습 능력을 갖는 인재를 양 성하기 위한 방법의 하나로 웹은 다양한 형태의 자료를 학습자 주도적으로 검색할 수 있고 상호작용을 촉진시킬 수 있는 많은 장점을 가지고 있다. 한편, 실과 교육의 특성상 가장 효과적인 교수 방법은 직접 체험 학습을 하는 것이나 비용, 환경 여건, 안전도, 시간을 고려해 볼 때 항상 직접 체험학습 환경을 제공해 주기는 어렵다. 이러한 제한점이 많은 실과 단원에 대하여 직접 체험 환경과 가깝고 자가 주도적 학습을 지원하는 형태의 웹 코스웨어를 개발하여 이러한 제한점을 보완한다면 실과교육의 학습 효과를 높일 수 있을 것이다. 따라서 본 연구는 시간 장소 공간의 제약으로 많은 어려움이 있는 7차 교육과정 초등학교 실과 6학 년 '동물 기르기' 단원 중심으로 웹 코스웨어를 설계 개발하고 수업에 간단히 적용해보았다. 프로그램 적용 및 평가에 대한 심도 있는 연구는 후속연구에서 진행하기로 한다.

인터넷 기술의 발달은 학교 현장에서 웹기반학습을 가능하게 하였고 새로운 교육 방법의 하나로 자리잡아가고 있다. 웹기반 학습에 대한 관심이 증가되면서 웹 활용에 대한 많은 자료와 방법들이 쏟아져 나오고 있어 교수-학습방법에 있어서는 활발하게 논의되고 있으나 상대적으로 학습자의 인격 형성에 중요한 요소인 사회적 상호작용을 통한 사회성의 발달과 같은 생활지도 측면은 소홀한 면이 있다. 본 논문은 웹기반학습에서 사회적 상호작용이 아동의 사회성 발달에 미치는 영향을 검증하고, 아동의 성격과 참여도에 따른 사회성의 변화를 분석하여 웹기반학습에서 아동의 사회성 발달을 적극적으로 유도할 수 있는 방안들을 함께 모색하는데 있다.

Prestressed hollow-core slabs (HCS) are widely used for modern lightweight precast floor structures because they are cost-efficient by reducing materials, and have excellent flexural strength and stiffness by using prestressing tendons, compared to reinforced concrete (RC) floor system. According to the recently revised ACI318-08, the web-shear capacity of HCS members exceeding 315 mm in depth without the minimum shear reinforcement should be reduced by half. It is, however, difficult to provide shear reinforcement in HCS members produced by the extrusion method due to their unique concrete casting methods, and thus, their shear design is significantly affected by the minimum shear reinforcement provision in ACI318-08. In this study, a large number of shear test data on HCS members has been collected and analyzed to examine their web-shear capacity with consideration on the minimum shear reinforcement requirement in ACI318-08. The analysis results indicates that the minimum shear reinforcement requirement for deep HCS members are too severe, and that the web-shear strength equation in ACI318-08 does not provide good estimation of shear strengths for HCS members. Thus, in this paper, a rational web-shear strength equation for HCS members was derived in a simple manner, which provides a consistent margin of safety on shear strength for the HCS members up to 500 mm deep. More shear test data would be required to apply the proposed shear strength equation for the HCS members over 500 mm in depth though.

Rapid Prototyping (RP) technologies provide the ability to fabricate initial prototypes from various model materials. Stratasys' Fused Deposition Modeling (FDM) is a typical RP process that can fabricate prototypes out of plastic materials, and the parts made from FDM were often used as load-carrying elements. Because FDM deposits materials in about $300\mutextrm{m}$ thin filament with designated orientation, parts made from FDM show anisotropic material properties. This paper proposes an analytic model to predict the tensile strength of FDM parts. Applying the Classical Lamination Theory, which was developed for laminated composite materials, a computer code was implemented. Tsai-Wu failure criterion was added to the code to predict the failure of the FDM parts. The tensile strengths predicted by the analytic model were compared with experimental data. The data and prediction agreed reasonably well to prove the validity of the model. In addition, a web-based advisory service was developed to provide to strength prediction and design rules for FDM parts.
