In this study, science teachers' and students' perceptions were searched on lectures and experiment of law of definite proportion in middle school science classes. For this study, the three teachers' lessons were observed and recorded, following interviews related to teachers' perceptions on the lessons and experiments. Also, We analyzed students' science scores, cognitive levels, science attitude, experimental reports, etc. According to the results, the three teachers had different focuses in the lectures. Chemistry teachers accentuated calculation of proportions and application rather than basic conceptions. But the students could not understand basic conceptions properly. The teachers spend long time to explain experimental procedures by assuming a low performance level of students in experimental classes. And the teachers had negative perceptions about error of results. The students could not understand the experiment results well, tried to manipulate data artificially, and had negative perceptions about error of results like the teachers. We suggested that these problems might be solved by changing teachers' perceptions on school science lectures and experiments.

This study shows the result of the security assessment of the nationwide key energy facilities and suggests the ways of improving the security level. According to the study, most of the energy facilities are adequately equipped with physical security factors such as security personnel, security systems, fences, and guard posts, but lack of awareness is pervasive among those concerned, so the security operation is inefficient. In other words, inefficient deployment of security personnel, lack of the fundamental knowledge of the security systems, excessive dependence on surveillance cameras' functions such as Pan/Tilt/Zoom, misplaced cameras, low efficiency of monitoring, and irrelevant security plans. To solve these problems, above all, the authority concerned need to develop professional training programs to secure certified security mangers, and need to standardize security process to ensure consistency and to harness the standardization as a source of self assessment to improve security level.

This paper introduces a new qualitative measurement indicator, Relatively Rank-normalized Impact Factor ($R^2nIF$) that can overcome drawbacks of the existing research performance measures. With the help of this innovative indicator, this study analyzes and compares the quality of research papers across countries and National Science Indicators (NSI) standard academic fields. The development of an improved bibliometric indicator for evaluating the quality of research papers and disentangling the "international" dimension of research performance will be of interest to academics and practitioners alike.

In order to investigate the factors influencing QOL and life satisfaction of the physically disabled, the author interviewed, by using structuralized questionnaire, 440 individuals among the physically disabled who were participated in Health Examination from April to July, 1997. The questionnaire consisted of the general characteristics(sex, age, marital status, family number, etc), the Reintegration to Normal Living Index(RNLI) to assess QOL, and the single item of five-likert scale to evaluate life satifaction. The means of RNLI were $16.2{\pm}4.8$ in total score, $12.2{\pm}3.4$ in daily functioning and $4.0{\pm}2.1$ in perception of self. The respondents were less reintegrated toward social activities and relationships than impairments or disabilities. While the satisfied group was 47.3%, the dissatisfied group was 52.7%. As the results of multiple regression and logistic regression analysis, the significant predictors of QOL were age, education, job, grade of disability and subjective health status. The life satisfaction were related to economic status, job and subjective health status. To improve QOL and life satisfaction of the physically disabled, it is important that we improve their basic socioeconomic status by getting a job through rehabilitation education and induce them to have positive self-assessment by extending the opportunity of social participation.

In the present study, we analyze four seventh grade students' recognition of geometric properties and the following justification processes while their adopting different construction approaches in GSP(Geometer's Sketchpad). As the students recognized dependency and level-1 invariants by dragging activities, they determined their own construction approaches. Two students, who preferred robust construction, immediately recognized the path of a draggable point and provided step-1 justification. The other students attempted soft construction followed by their recognition of level-2 invariants and the path, and came to step-2 justification.

This paper examined the educational objectives of selected colleges of engineering in Korea and other countries such as the USA, Canada, Australia, New Zealand, Japan, and Hong Kong. Among the common educational objectives of the colleges of engineering in Korea are the supply of manpower with professional abilities, an education to enhance the basic competence of engineers, and the equipment of high-level educational environments for quality engineering education. These emphases are in line with the global trends shown in the cases of various countries, where "leadership" and "innovation" are given much weight, and qualities such as "creativity", "specialty", and "service" are stressed. The analysis on the educational objectives of the selected colleges of engineering listed in this study may serve as a substantial basis for setting future goals and making decisions for quality engineering education in the colleges of engineering.

Although many certification works have been carried out since Green Building Certification was enforced in 2002, analyses of the effects and efforts to improve this system are still poor. In the certification system, the energy performance was usually assessed by Energy Performance Index(EPI) of the Energy Saving Design Standards for Buildings. However, due to the inadequacy of analyses on current situation of the Index, there are difficulties to reform it. In this research of green-certified apartments, the author examined correlations between energy performance indexes and aimed to improve the Index by analyzing the scores based on point distribution of respective fields. The average EPI score of green-certified apartments was 74.68, and there was wide variations in min 63.4 and max 90. Furthermore, the average score of energy consumption, which was allotted the most points, was 7.04 out of 12. Therefore, betterments in the Index such as reinforcement in grade ranges and adjustment of the calculation method are necessary.

도시주민들은 경제, 문화생활 및 의식수준이 향상됨에 따라 보다 다양하고 양질의 공공서비스를 요구하게 되었다. 주민들의 이러한 요구는 공공서비스 시설의 입지문제와 직결되는 것으로 도시의 입지결정 시 가장 중요한 고려사항 중의 하나는 공공서비스를 보다 저렴하고 편리하게 시민들이 이용할 수 있게 제공함으로써 이용주민들의 복지를 극대화 시켜야한다는 점이다. 이러한 기본 목적을 충족시키기 위해서는 공공시설의 위치결정이 중요한 문제가 된다. 본 논문에서는 접근성 이론과 GIS 공간분석 기법을 접목하여 입지분석을 시행하였으며 연도별 최적입지를 산출하고, 각 구청의 연도별 최적 입지점의 지도화를 통해 그들의 이동 추이를 추적하며 각 구청의 연도별 최적값의 변화 추이를 살펴보았다. 또한 비교분석을 통하여 연도별 현구청의 입지 혹은 이전할 입지의 적합성을 평가하였다. 이를 위해서 입지분석을 위한 이론적 검토로서 공공서비스 시설의 입지이론에 대해 살펴보고 구청사의 입지 적정성을 객관적인 기준에 따라 평가할 수 있는 계량적인 입지분석 방법을 검토 정립하였다. 본 연구에서는 이론적인 근거를 실제 공공시설적용을 위하여 금천구를 선정하였고, 구청의 도시현황을 분석하고, 도로망, 인구추정을 통하여 관련자료를 수집하였다. 이를 토대로 정성적, 정량적 분석 및 효율성과 형평성을 고려하여 구청사 위치의 적정성에 대한 결론을 도출하였다.

TIMSS (Trends in International Mathematics and Science Study) aims to produce reliable and internationally comparable indicators of student achievement. The TIMSS science achievement scale summarizes student performance on test items designed to measure a wide range of student knowledge and proficiency. This study analyzed Korean middle school students' science achievement at the advanced and high international benchmarks of the four benchmark levels of the benchmarks classified in TIMSS 2003 in light of science content areas (physics, chemistry, biology, earth science, and environmental science) and item characteristics. The average percent correct on items at the advanced benchmark by Korean students was highest in physics followed by earth science, biology, chemistry, and environmental science, whereas internationally the order was earth science, chemistry, biology, physics and lastly environmental science. Korean students performed relatively better in physics yet somewhat worse in chemistry than other top-performing countries. According to item analysis, Korean students reaching the advanced international benchmark understood some fundamentals of scientific investigation, but demonstrated weakness in written explanations of scientific principles, abstract science concept comprehension, and application of scientific concepts to solve quantitative problems. In addition, Korean students reaching the high international benchmark demonstrated relative weak conceptual understanding of ecology compared with other countries.

게임에서의 텍스트를 추출하고 이를 분석하고자 하였다. 기본적으로 그레마스의 구조생성기호학을 활용하여 텍스트를 분석하고자 하였는데, 연구방법론에서는 현상학, 해석에서는 정신분석학의 이론에서도 도움을 받았다. 구체적인 분석대상으로는 온라인게임인 스타크래프트, 리니지, 스페셜포스를 선택하였다. 연구문제는 이들 세 게임의 의미생성방식에 대한 탐구로 구성되었다. 각 게임의 의미생성방식은 구조생성기호학의 세 가지 층위에서 구분되어 연구되었다. 즉, 심층구조, 기호-설화구조, 담화구조의 세층위로 전환, 발화되면서 점진적으로 의미가 풍성해지는 과정이 탐구되었다. 각 게임의 차이, 나아가 게임 장르간의 차이는 주로 심층 수준의 차이에서 기인한다고 보인다. 이들 게임의 주요 공통점이자, 다른 매체와의 차이점은 행동자 모델에서 두드러지는데, 바로 이용자가 스스로 주체의 위치를 점하게 되는 것이다. 상호작용성으로 대변되는 게임의 특성은 이용자의 텍스트로의 적극적인 개입을 할 수 있게끔 한다. 이러한 적극적인 개입은 이용자가 스스로 텍스트의 주체가 되도록 허용하는데, 주체가 된다고 함은 곧 스스로의 욕망을 직접 대상에 투사하면서 텍스트를 창출함을 의미한다. 바로 이러한 점이 게임의 의미생성방식의 큰 특징이며 다른 매체들과의 주요한 차이점이기도 하다. 더불어 게임이 우리 문화와 사회에 커다란 영향을 미칠 수 있는 기제임이 입증되는 것이기도 하다.
