LAMS(learning activity management system)[1] is one of the useful tools for designing and managing effectively the learning activities such as web search, chat, forum, grouping, and board. Even if LAMS has been upgraded to support the methods for making e-Learning contents conveniently, it does not have a method to communicate with external educational contents (EEC) made by external tools like Flash, Java, Visual C++, and so on. LAMS, which has been operated on Web environment, should manage all EECs like video and dynamic educational contents as educational contents in LAMS database. However, the current LAMS does not support the functionalities which can provide information of EECs to LAMS database and can also access any information about EECs from the database yet. In this paper, we propose the communication mechanism between the LAMS and EECs for solving the problem. In special, the mechanism makes many statistical data by using the information, and provides them for reflecting in education, and can control various learning management that was impossible under the original LAMS. Based on the proposed mechanism, teachers using LAMS can make more various educational contents and can manage them in the system.

The development of communication technology and the spread of computers and internet have affected to the field of education. In this paper, we design a learning process with LAMS to make the new education environment which is required in an information age. We made the learning environment with LAMS which develops the learner's algorithmic thinking faculty on some sorting algorithm, especially such as selection sort, bubble sort and insertion sort algorithm. In addition, we analyse the effectiveness of the learning environment. The designed contents were applied to elementary school students' learning and a questionnaire survey was conducted after a learning course. The research of the questionnaire shows that the learning system using LAMS motivates a learner for learning and provides a convenient learning environment.

Even after Hwang Woo Suk's research ethics scandal in Korean research fields, there are still research ethic problems that are present in the Korean society. In order to spread research ethics education around Korea, there needs to be sufficient amount of research ethics contents prepared, which then can be used to educate and put into action. Through the usages of the scope of research ethics, comparing and contrasting several examples from domestic illegal research acts and American research ethics education, and the Learning Activity Management Systems (LAMS), we would be able to develop a way to manage the research ethics education. Also, in order to fully use and apply the necessary contents and material for the research ethics education program in several universities, we would not only need to use the LAMS system to establish the training system, but also to spread the awareness of research ethics.

In this paper, we propose a new Two-factor Authentication and Key Exchange(TAKE) protocol that can be applied to low-power PDAs in Public Wireless LAMs using two factor authentication and precomputation. This protocol provides mutual authentication session key establishment, identity privacy, and practical half forward-secrecy. The only computational complexity that the client must perform is one symmetric key encryption and five hash functions during the runtime of the protocol.

The aim of this paper is to help learners develop algorithmic thinking skill to solve a problem using LAMS and to draw their interest in learning through various learning activities to solve it. LAMS has the advantages of easy teaching contents' design and implementation and of an offer of sequential learning under various learning environments. The designed contents were applied to elementary school students' learning and a questionnaire survey was conducted. They showed positive responses, on the one hand, they hoped that various kinds of learning would be provided including not only data sorting but also technical contents related to computer. For further study, it is necessary to revise and supplement conceptual principals or contents of computer education in elementary and junior high schools.

컴퓨터와 인터넷이 발달과 함께 웹을 이용하여 다양한 학습 방법들이 개발되고 있다. 학습 활동 관리 시스템 LAMS는 효과적으로 학습 활동을 설계하고 관리할 수 있는 유용한 도구 중 하나이다. 하지만 LAMS가 우리가 플래시나 자바와 같은 외부 도구로 만든 외부의 사용자 콘텐츠들과 아무런 통신이 이루어지지 않기 때문에 완벽하게 학습 활동을 관리하지는 못한다. 본 논문의 목적은 이러한 문제를 해결하기 위해 LAMS와 외부의 사용자 콘텐츠가 서로 통신을 할 수 있는 통신 메커니즘을 설계하고 구현하는 것이다. 이를 위해 웹 기반 교육과 LAMS의 구조와 기능 및 개발 환경에 대해 분석 하였다. 이러한 분석을 기반으로 LAMS와 외부 교육용 콘텐츠 사이의 통신 메커니즘을 설계하고 구현하였다. 이러한 메커니즘을 플래시나 자바 또는 비주얼 C++로 만든 콘텐츠에 적용할 수 있으며, 이 콘텐츠들은 LAMS의 정보를 가지고 오거나 LAMS에 정보를 전달할 수 있다. 그리고 이러한 정보를 모아 각종 통계 자료를 만들고, 이를 교육에 반영할 수 있다. 이 메커니즘은 다양한 개발 환경에서 동작하며, 이것을 이용하여 기존의 LAMS에서는 불가능했던 다양한 학습 관리가 가능하도록 하였다. 우리는 이메커니즘을 이용하여 좀 더 혁신적인 콘텐츠를 개발하고 우수한 학습 활동 관리 시스템을 구축할 수 있을 것이다.

The convergence of libraries, archives, and museums (LAMs) has garnered attention in recent years. Extending the tendency further, National Taiwan Normal University (NTNU) fuses the library, archive, museum, and publisher (LAMP) functionality together in its library. This article elaborates on the LAMP practices of the NTNU Library, which indicates that without creating new units in a university, its library can play a good role of curating invaluable university assets.

With the reformation of organization and function of local office of education in 2010, consulting-supervision is introduced to schools as a system for education reform to improve the quality of school education. However, a dedicated on-line portal system that can provide integrated management on the functionalities of consulting-supervision has not been implemented yet. To successfully operate consulting-supervision in schools, it is also needed to provide an on-line consultant education system, that can support teachers to train themselves as a supervision-consultant. In this paper, we introduce an on-line consultant training system that provides various learning activity tools for consultant training based on Learning Activity Management System(LAMS) and Action Learning. The system consists of Management stage, Analysis stage, Solution stage, and Action stage for the empowerment of consultants' expertises, and is named as MASA. Brain-writing, SWOT(Strengths, Weaknesses, Opportunities, and Threads) analysis, 5Whys, decision grid, PMI(Plus, Minus, Interesting), and black chart techniques were developed in MASA as learning activity tools for consultant training.

We propose a new resource management scheme, Distributed Channel Allocation Protocol (DCAP), for multimedia Ad Hoc Wireless LANs (AWLANS). This scheme implements a Qualify-of-Service (QoS) providing distributed resource management on the Orthogonal Frequency Division Multiplexing-Code Division Multiple Access (OFDM-CDMA) channel architecture. According to the performance evaluation results for MPEG traffic sources, DCAP can be a good choice of resource management scheme for AWLANs supporting multimedia services on the Broadband Wireless Access(BWA)-type physical layer.

It is well known that there is an inverse relationship between the strength of Indian summer monsoon Rainfall (ISMR) and extent of Eurasian snow cover/depth in the preceding season. Tibetan snow cover/depth also affects the Asian monsoon rainy season largely. The positive correlation between Tibetan sensible heat flux and southeast Asian rainfall suggest an inverse relationship between Tibetan snow cover and southeast Asian rainfall. Developments in Regional Climate Models suggest that the effect of Tibetan snow on the ISMR can be well studied by Limited Area Models (LAMs). LAMs are used for regional climate studies and operational weather forecast of several hours to 3 days in future. The Eta model developed by the National Center for Environmental Prediction (NCEP), the Fifth-Generation NCAR/Penn State Mesoscale Model (MM5) and Regional Climate Model (RegCM) have been used for weather prediction as well as for the study of present-day climate and variability over different parts of the world. Regional Climate Model (RegCM3) has been widely . used for various mesoscale studies. However, it has not been tested to study the characteristics of circulation features and associated rainfall over India so far. In the present study, Regional Climate Model (RegCM-3) has been integrated from 1 st April to 30th September for the years 1993-1996 and monthly mean monsoon circulation features and rainfall simulated by the model at 55km resolution have been studied for the Indian summer monsoon season. Characteristics of wind at 850hPa and 200hPa, temperature at 500hPa, surface pressure and rainfall simulated by the model have been examined for two convective schemes such as Kuo and Grell with Arakawa-Schubert as the closure scheme, Model simulated monsoon circulation features have been compared with those of NCEP/NCAR reanalyzed fields and the rainfall with those of India Meteorological Department (IMD) observational rainfall datasets, Comparisons of wind and temperature fields show that Grell scheme is closer to the NCEP/NCAR reanalysis, The influence of Tibetan snowdepth in spring season on the summer monsoon circulation features and subsequent rainfall over India have been examined. For such sensitivity experiment, NIMBUS-7 SMMR snowdepth data have been used as a boundary condition in the RegCM3, Model simulation indicates that ISMR is reduced by 30% when 10cm of snow has been introduced over Tibetan region in the month of previous April. The existence of Tibetan snow in RegCM3 also indicates weak lower level monsoon westerlies and upper level easterlies.
