Accountability for computer technology expenditures is a hot issue at the national educational level. Justification for this expenditures is being question by many people, as well as the effects of technology have a positive impact on student achievement. Despite the availability of technology, individual classroom teachers tend to avoid the use of computer-based technologies(Rogers, 2000). Knezek, Christensen, Hancock, and Shoho (2000) tried to find out if technology investment can contribute to student achievement using a model for integrating technology into the classroom. The model contains three indicators of teacher attributes in the areas of will, skill, and technology. Two teacher self-report measures of technology integration are used as outcome measures for the level of technology infusion into the classroom. The model was started from the hypothesis for technology integration to have a positive impact on student achievement. In the model Knezek, et al.(2000) focused on only the teacher without thinking of the relation of student and learning environment for technology integration into the classroom. According to Rogers(2000), Krysa(1998), Duttweiler(1983), and Maddux(1998), there are many barriers from external and internal sources to technology adoption. Then Knezek et al(2000) do not consider these obstacle's elements to integrate technology into the classroom. The purpose of this article is to examine a synthesized model for integrating technology into the classroom through previous research from Knezek et al.(2000) and Rogers(2000). The model started from the research of Knezek et al. (2000) has formulated a model with three key elements to be necessary components for effective integration of technology into the teaching/learning environment of the classroom. The model also is based on research studies on barriers to technology adoption(Rogers, 2000; Krysa, 1998; Duttweiler, 1983; Maddux, 1998). There are four characteristics in the new model. First, the model is presented along with considering that not only the teacher, but also the student and educational environment of a computer technology classroom can contribute to student achievement. Second, the model includes three basic elements of relation with integration of technology: teacher and student attitude(will), skills of technology competency, and access hours to technology. Third, the model can be a way to overcome the barriers of computer technology into the classroom. Finally, the model also showed the assessment possibility of stages of adoption of computer technology into the classroom. However, the model has to be warranted further testing in additional studies. One important aspect contentiously identified is the predictability of student achievement based on the level of technology integration. Other important aspects to be tested are the predictability of classroom technology integration based on teacher and student measures of will, skill, and access to technology. The other important aspect is how to measure five key elements of technology in the learning environment: social and political views, technical support, education, budget, and quality/quantity of hardware and software. The three components operating as equal integral parts will result in a better overall student achievement.

전반적으로 일반산업체의 주문생산에 의존하고 있는 독일의 장애인직업재활시설은 일반사업체의 작업공 정과정의 자동화, 아시아·동유럽국가간의 가격경쟁으로 지속적인 일거리를 유지하는데 어려움을 겪게 되 었다. 이에 직업재활시설은 컴퓨터 자동화된 기계 특히, CNC(Computerized Numerical Control) 기계를 도입하여 부가가치가 높은 작업을 장애인근로자에게 제공하여 뚜렷한 수익성과를 보았다. 그러나 직업재활시설의 궁극적 목적인 장애인의 인성발달 및 촉진에 대한 성과는 불투명하였고, 지금까지 이에 대한 조사·연구도 거의 이루어지지 않았다. 본 연구는 이러한 이론적인 배경과 문제를 바탕으로, CNC 기계를 통해 자동화된 작업이 일반 수동기계로 수행되는 작업에 비해 직업재활시설의 핵심과제인 장애인의 인성 촉진에 미치는 영향을 알아보고자 하였다. 제기된 연구문제에 따라 직업재활시설 금속작업영역에 CNC 기계로 작업하는 지적장애인 35명(실험집단)과 일반 수동기계를 다루는 지적장애인 28명(비교집단)을 대상으로 이들의 주관적·객관적 작업환경과 인성을 조사하였고 두 집단간에 비교하였다. 이 밖에도 CNC 기계사용 유무에 따른 주관적·객관적 직무환경과 인성지표간의 연관성을 분석하였다. 연구결과에 의하면, 작업 수행 시 CNC 기계사용 유무에 따른 주관적 작업환경과 인성과 관련하여 미미한 차이를 보였으나 객관적 작업환경에는 뚜렷한 차이를 나타냈다. 그리고 CNC 기계사용 유무에 따른 주·객관적 작업환경의 차이는 두 집단간에 차이를 나타내는 인성에 영향을 미치지는 않았다. 본 연구결과는 컴퓨터공학 작업기계 사용만으로는 직업재활시설 장애인들의 인성촉진을 기대할 수 없음을 제시하였다. 따라서 이들의 전인성 발달을 위해서는 직업재활시설 상황에 적합하고 근로장애인 개인의 직업적 능력과 적성, 흥미를 고려한 직무설계가 개발되어야 한다.

In increasingly competitive markets the introduction of new technologies in the production process, especially CNC (Computerized Numerical Control) technologies have become indispensable for sheltered workshops. These applications offer job opportunities for persons with mental retardation, but also change the conditions of work. This article deals with the contribution of CNC technology, compared to conventional machines, on the personality development of the mentally disabled. An empirical study has been carried out at 6 sheltered workshops with 35 mentally retarded employees (quasi experimental group) who worked with CNC machines, and 28 employees (control group) with conventional machines. Both groups have been compared according to their perceived and objective conditions of work and their attributes of personalit. The results suggest that IT-based working equipment does not necessarily help to enhance the personality development of mentally retarded employees. These technologies must be accompanied by individual measures at the working place that comply with the needs, wishes and capabilities of the mentally retarded.

본 연구는 콰욜라 작품에서 컴퓨터 알고리즘 기술이 주체로서, 인간이 재현한 이미지를디지털 이미지로 재창조하는 데서 발생한 숭고적 의미와 특성을 고찰한다. 그리고 이를 통해콰욜라 작품이 인간중심성을 비판적으로 성찰한다는 점을 살펴본다. 숭고에서 주체는 변형되고 비결정화되어 이전과 다른 창조적 자아로 거듭난다. 숭고에서 주체의 이런 양상은 주체로서 알고리즘 기술이 대상에 야기하는 현상과 유사하다. 알고리즘 기술은 대상을 데이터화함으로써 대상에 창조적 잠재력을 준다. 데이터로서 비결정화 된 대상은 다른 존재들로 다시변형되어 이전과 불일치할 가능성을 갖기 때문이다. ≪포로들 #B06 Captives #B06≫ (2014)과 ≪유적: 프로방스 Remains: Provance≫(2016)에서 알고리즘 기술은 대상을 변형, 비결정화 하고 이전과 불일치하게 만들어 대상에 창조적 잠재력과 숭고적 특성을 준다. 그래서 인간 시각에 대한 차이를 발생시켜 인간 시각과 근본적으로 같지만 다른 형태를 지니는 기계의 시각을 제시한다. 그리하여 알고리즘 기술은 인간이 기계의 시각을 통해 자신에대한 메타적 보기를 가능케 한다.

This study explores the meaning and characteristics of the sublimeness brought forth by computer algorithm technology while it transforms human-created images into digital images. In the process, this paper will examine Davide Quayola’s works and show that they are indeed an attempt to critically reflect on anthropocentrism. In the sublime theory, the subject is metamorphosed into an indeterminate entity, and thus creatively reborn. This parallels the phenomenon that algorithm technology, as subject, induces to objects. Algorithm technology affords creative potential to objects by turning them into digital data. In Captive #B06 and Remains: Provence, algorithm technology metamorphoses objects and makes them indeterminate and disagreeing with their previous status, giving them creative potential and the characteristics of the sublimeness. The mechanical view that algorithm technology creates is fundamentally the same as the human view, but has a different form. Therefore, algorithm technology enables humans to meta-view themselves through the mechanical views.
