정보통신기술(ICT: Information & Communication Technology) 활용 학교 교육을 활성화하기 위해 ICT 활용 교수-학습 모형과 과정안을 개발, 적용하고 ICT를 활용한 자기주도적 학습 능력을 신장할 수 있는 수업 방안의 연구가 필요하다. 그러나 이와 같은 필요성이 있는데도 ICT가 교육헌장에서 효과적으로 활용되고 있다고는 보기 어렵다. 기존의 강의와 학습자료를 단순히 인터넷으로 제공하는 형식의 기능적 ICT 활용교육이 어느 정도의 학습 효과를 창출할 것인지 문제는 결국 ICT를 효과적으로 활용할 수 있는 교수-학습을 설계해야 한다는 과제를 제시하고 있다 본 연구는 이와 같은 문제의식에 따라 먼저 ICT 활용 교육에 대하여 고찰한 결과를 학생 중심 학습환경을 제공하는 프로젝트 학습에 적용하여 ICT를 활용한 프로젝트 학습 모형을 설계하고 학습을 지원해 줄 학습 시스템은 상호작용 기능과 피드백에 중점을 두어 설계하였다

Recently, the research on ICT (Information and Communication Technology), which cognizes and communicates human's emotion through information technology, is increasing. For instance, there are researches on phones and services that perceive users' emotions through detecting people's voices, facial emotions, and biometric data. In short, emotions which were used to be predicted only by humans are, now, predicted by digital equipment instead. Among many ICT researches, research on emotion recognition from face is fully expected as the most effective and natural human interface. This paper studies about sensitivity ICT and examines mechanism of facial expression recognition system as an example of sensitivity ICT.

Utilization of IS is increasing in businesses: many organizations have established information systems(IS) and are using it as a means to innovate and communicate their businesses. But the expansion of IS utilization lead to the negative influence of ICT-induced stress on information system users. This study suggests IS utilization ability, IS self-efficacy, and pace of change as precedence factors of ICT-induced stress, and explains that ICT-induced stress influences Employee Productivity. The result shows self-efficacy and Pace of Change had significant effects on ICT-induced Stress. Also it had negative effects on Employee Productivity. In conclusion the study proposed that information system users' Performance decreases by ICT-induced stress.

Background: Fish and fishery products (FFPs) unintentionally contaminated with various environmental pollutants are major exposure pathways for humans. To protect human health from the consumption of contaminated FFPs, it is essential to develop a systematic tool for evaluating exposure and risks. Objectives: To regularly, accurately, and quickly evaluate adverse health outcomes due to FFPs contamination, we developed an automated dietary exposure and risk assessment system called HERA (the Human Exposure and Risk Assessment system for chemicals in FFPs). The aim of this study was to develop an overall architecture design and demonstrate the major features of the HERA system. Methods: For the HERA system, the architecture framework consisted of multi-layer stacks from infrastructure to fish exposure and risk assessment layers. To compile different contamination levels and types of seafood consumption datasets, the data models were designed for the classification codes of FFP items, contaminants, and health-based guidance values (HBGVs). A systematic data pipeline for summarizing exposure factors was constructed through down-scaling and preprocessing the 24-hour dietary recalls raw dataset from the Korea National Health and Nutrition Examination Survey (KNAHES). Results: According to the designed data models for the classification codes, we standardized 167 seafood items and 2,741 contaminants. Subsequently, we implemented two major functional workflows: 1) preparation and 2) main process. The HERA system was developed to enable risk assessors to accumulate the concentration databases sustainably and estimate exposure levels for several populations linked to seafood consumption data in KNAHES in a user-friendly manner and in a local PC environment. Conclusions: The HERA system will support policy-makers in making risk management decisions based on a nation-wide risk assessment for FFPs.

It is difficult to prevent and solve the contrary function of informationized society by a coercive or physical way. It is believed that a systematic education, teachers, experts, parents and students of schools are to be united as one to put every effort on preventing the contrary function of informationized society. In this study, ICT ethics behaviour test system has been designed and implemented with the aim of setting up an appropriate sense of values and cultivating ICT ethics index of juveniles. ICT ethics behaviour test system developed is to meet the contrary function of informationized society actively so the system should prevent the negative phenomenon derived from it. And it is expected to help the system build up the ability of keeping and developing the primary function of informationized society.

Even though Korea is No.1 shipbuilding country around the world, there have been a lot of accident and man-made calamity incurring in shipyards these days. Therefore most of Korea major shipyard and mid-small size shipyard deeply agonize about safety management countermeasure. As a result of it, many shipyards pour their effort on developing man watching system, PF wireless communication system, portable measuring system to prevent from accident such as fire, suffocation incurring. In this paper, analyze conventional accident & man-made calamity preventing system adopted by most of shipyard and enable the user to watch accident for 24 hours and notify it to user when it is incurring through state of the art ICT technology. And as a result of it the user can prevent the accident and man-made calamity at the beginning.
