최근 국내 교육계의 최대 관심인 ICT 활용 교육은 활용 측면이 지나치게 강조되고 있고, ICT 활용 교육에 대한 연구도 실용적인 측면만이 부각됨에 따라 기능적인 활용으로 치우칠 수 있다는 우려를 낳고 있다. 본 연구는 이에 대한 대안으로서 ICT 활용을 이론적 차원에서 모색하여 효율적인 ICT 활용을 위한 구체적인 전략을 마련하고자 하였다. 먼저, 효율적 ICT 활용의 개념을 정의하였고, 전략 도출을 위한 기초 준거로 인간의 고등 사고를 설정하여 비판적 사고를 포함한 Iowa 교육부의 통합 사고 모형을 분석하였다. 이를 통해 효율적 ICT 활용을 위한 종합적 사고를 범주화하였다. 또한, 효율적 활용을 위한 ICT를 소프트웨어, 하드웨어, 활용 기술 영역으로 분류하여 각각의 개념과 상호 관계를 살펴보았다. 이렇게 분류한 ICT의 각 영역과 종합적 사고 범주와의 관련성을 규명하기 위해 '사고 영역과 ICT 영역간의 관련성 결정 준거'를 논의하였고, 이를 구체화한 'ICT-EUS 도출을 위한 분석 매트릭스'를 설정하여, 도출 과정의 타당성과 도출 결과의 명확성을 확보하고자 하였다. 이와 같은 과정을 통해 최종적으로 ICT의 영역 중 학습 자원, 학습 도구, 학습자, 탐색, 의사소통, 생산, 표현에 대한 ICT-EUS(Efficient-Use Strategy of ICT; 효율적 ICT 활용 전략)를 도출하였다. ICT-EUS는 ICT의 단순한 활용을 넘어서 학습 자원, 도구, 활용 기술 등에 대한 인지적 해석을 통해 학습 목표 달성의 효율성과 효과성을 제고할 수 있는 가능성을 제공할 수 있을 것으로 기대한다.

주문형 교육 시스템(EOD)에서 스케쥴링 기법은 시스템의 효율을 높이고, 한번의 디스크 검색으로 여러 학습자들의 요구를 만족시키도록 설계되어야 한다. 이에 본 논문에서는 학습자 시스템의 자원을 활용함으로 서버의 디스크 입출력과 버퍼 소비를 줄이는 스케쥴링 기법을 제안하였다. 본 논문에서 제안한 스케쥴링 기법은 모든 서비스를 서버가 제공하는 것이 아니라 해당 자료를 저장하고 있는 학습자 시스템으로 하여금 서비스하도록 한다. 그럼으로써 학습자들의 초기지연시간 단축을 가져오고 서버의 처리량이 증가하게 된다. 본 논문에서 제안한 기법과 기존의 기법의 성능을 시뮬레이션으로 비교한 결과 제안한 기법이 효율적인 성능을 나타냈다.

Glucoamylase is an important industrial enzyme. Glucoamylase production by industrial Aspergillus niger strain featured with two major problems: (i) empirical substrate feeding methods deteriorating the fermentation performance; and (ii) the high raw materials cost limiting the economics of the glucoamylase product with delegated specification. In this study, we first proposed a novel three-stage varied-rate substrate feeding strategy for efficient glucoamylase production in a 5 L bioreactor using the standard feeding medium, by comparing the changing patterns of the important physiological parameters such as DO, OUR, RQ, etc., when using different substrate feeding strategies. With this strategy, the glucoamylase activity and productivity reached higher levels of 11,000 U/ml and 84.6 U/ml/h, respectively. The performance enhancement in this case was beneficial from the following results: DO and OUR could be controlled at the higher levels (30%, 43.83 mmol/l/h), while RQ was maintained at a stable/lower level of 0.60 simultaneously throughout the fed-batch phase. Based on this three-stage varied-rate substrate feeding strategy, we further evaluated the economics of using alternative carbon sources, attempting to reduce the raw materials cost. The results revealed that cornstarch hydrolysate could be considered as the best carbon source to replace the standard and expensive feeding medium. In this case, the production cost of the glucoamylase with delegated specification (5,000 U/ml) could be saved by more than 61% while the product quality be ensured simultaneously. The proposed strategy showed application potential in improving the economics of industrial glucoamylase production.

Even though the distance education via web has a great advantage to overcome time and space, its problem is that the management of trainees is not efficient compared with classroom and group education. This problem is a great obstacle to the objects and achievement standards of distance education, giving controversial arguments to the advocators of distance education. Distance educators need to monitor the trainees'participation and responses continuously and offer appropriate feedback to the trainees. However, the existing distance education system only focuses on teaching and learning activities, and as a result, the efficient management function of distance education is not available. Accordingly, the study attempts to find out the appropriate managing elements of distance teacher training in order to effectively achieve the goals of teacher training and the efficient management of distance education. Also, it proposes distance teacher training management system that offers appropriate feedback to trainees, applying the derived elements of distance teacher training to the training processes. To verify the efficiency of the system, hypotheses on related items of distance teacher education and learning types are suggested, and the achievement degree of learning and its relations are investigated through questionnaire of learning types. In addition, a system using UML which is the standard of object-oriented modeling language is devised, so. that mutual management, language independence and convenient development environment as well as reusability can be offered, and so the design standardization and efficient system realization could be achieved, while flexible change of system according to education process and computing environment is possible.

The aim of this study is to apply lesson design of high school home economics to model which consists of six steps of instructional procedure among various models for instructional design, Through thesis, central content of each step was written as follows; 1) At the step of establishment of terminal instructional objectives, educational objectives, terminal instructional objectives was analyzed and specific instructional objectives was extracted. 3) At the step of diagnosis of entering behavior, ability of prior learning and ability of preliminary learning were evaluated, which was used as establishing instructional strategy and doing individual guidance. 4)At the step of determining instructional strategy, instructional strategy should be extracted by considering instructional event which is adequate to content of instruction. Instructional strategy consists of five main factor, factors, those are, activity of introduction of instruction, presentation of content of instruction and information, participation of learner and learning activity, identification of learning result, and subsequent treatment after evaluation. 5)Specific activity at the step of selection and development of instructional media consists of reidentification of instructional objectives determination of learning type, drawing up instructional media analysis sheet, synthesis of selected media, and explanatory note of selected media. In order to increase efficiency of instruction at the step of determining instructional strategy, this step should be considered simultaneously. 6)The step of try-out and evaluation of instructional design should be efficient when designed instruction was inputted at class after evaluation of each step of instructional design.

The study was to explore the housework time management strategies and time spent in housework of employed wives and to understand the variables influenced on them. The samples were composed of 271 employed wives living in Chunlabuk-Do. The results were as follows: 1) The employed wives spends average 4.5 hours a day on the housework. The significant differences were ground in the housework time related to all demo-graphic variables. 2) The level of the housework time management strategies of employed wives was lower than the average. The most influential variable on the housework time management strategies of employed wives was the level of education the monthly income and employment types. A employed wives with the higher work status education level and income level utilized more efficient time strategies. 3) The major strategy which influences the housework time is that of simplification. Especially occupation of housewives and type of house interact with the strategy of sim lification. That is as the housewives with the jobs of blue-collar production-technology and clergycal technology use the simplification strategy much their amount of housework time was reduced.

According to the double-phase cluster-head election method (DCE), the final cluster heads (CHs) sometimes are located at the edge of cluster. They have a long distance from the base station (BS). Sensor data is directly transmitted to BS by CHs. This makes some nodes consume much energy for transmitting data and die earlier. To address this problem, energy efficient multi-hop cluster-head election strategy (EEMCE) is proposed in this paper. To avoid taking these nodes far from BS as CH, this strategy first introduces the distance from the sensor nodes to the BS into the tentative CH election. Subsequently, in the same cluster, the energy of tentative CH is compared with those of other nodes, and then the node that has more energy than the tentative CH and being nearest the tentative CH are taken as the final CH. Lastly, if the CH is located at the periphery of the network, the multi-hop method will be employed to reduce the energy that is consumed by CHs. The simulation results suggest that the proposed method exhibits higher energy efficiency, longer stability period and better scalability than other protocols.
