Reducing the logistic cost may be accomplished by numbers of logistic management methods, but the most fundamental and essential one is the accomplishment of the consistent reverse logistics system that is the core of worker performance system, and the purpose of consistent reverse system is the treatment of logistic functions such as transportation, storage and unloading with consistent logistics, and increasing the turnover ratio is required for the improvement of the system. As the turnover ratios is increased, this paper make reverse worker performance evaluation system with lifetime value include of weight variables.

2002학년도부터 시행되고 잇는 제 7차 교육과정은 수준별 학습을 요구하고 있으나 교사가 실제 사용할 교수학습과정은 제시되어 있지 않다, 따라서 이 연구는 고등학교 과학수업에 적용할 수준별 교수학습과정을 개발하고 이를 학습에 적용하고 그 효과를 과학관련 태도와 학습 성취도 및 수준별 교육과정에 대한 인식의 변화를 통하여 알아보는데 있다. 그 결과는 다음과 같다. 1) 고등학교의 수준별 학습의 운용형태에 따라 두 가지 형태의 교과학습 과정안을 개발하였다. 하나는 수준별 학습이 동시에 이루어질 때 사용하는 것이고 또 하나는 수준별로 학생들을 분반하여 학습하는 형태이다. 이들 중 동시에 학습하는 형태를 실제 수업에 적용하고 그 효과를 조사하였다. 2) 수준별 학습에 대한 인식에서 학생들은 이 교육과정의 중요성을 인식하면서도 동시에 수행되는 수준별 학습에 대해서는 좋은 인식을 주지 못했으며 과학과 관련된 태도에서는 우의미한 변화가 나타났다.

Facing the 7th National Curriculum revision, this study aims to suggest the ideas for the curriculum design for the second foreign languages education. For this purpose, the theoretical analysis of curriculum theory and examination into commentaries, guidebooks, training materials and curriculum documents related to the foreign languages education are carried out. The theoretical analyses carried in the study are as follows: The analysis of curriculum objectives and contents for foreign languages education in terms of the findings and implications the existing researches suggested is carried and so the current issues and major ideas are identified. The contents analysis for the foreign languages education implemented in foreign countries is carried and so the future directions for curriculum objectives and contents of the second foreign languages education in Korea are suggested. The major suggestions are made through above analysis as follows: The differentiation of the subjects for the second foreign languages education by the curriculum objectives and contents is required. Whether the oral language communicative competence focused or the written language communicative competence focused should be considered in establishing the curriculum objectives and contents. The curriculum objectives and contents are required to state clearly and effectively. The directions for culture education are required to change and the contents for culture education are required to be reorganized systematically.

This paper analyzes the high school textbooks for German which were developed according to the guidelines of the 7th National Curriculum. The study focuses on communicative features of texts/dialogues and the lessons in general. According to 7th National Curriculum, students have to practice all four communicative activities in German I, namely listening, speaking, reading and writing. This analysis aims at identifying and analyzing the elements which are relevant for communicative exercises. For that purpose, the author analyzes the proportion of texts in relation to dialogues, and the therein contained distribution of communicative situations or themes; another aspect of analysis deals with the question, how systematically the lessons are structured in order to enhance the four communicative activities and skills.

When the importance of various cu1tures is emphasized more and more, 1earning various languages can a1so keep off the cultural standardization. But today the second foreign 1anguage education is facíng a serious crisis. The balance of foreign 1anguage learners is not proper. The environment for learning the second foreign languages is getting worse. In the seventh curricu1um the credit hour will be reduced. Moreover, students staπ to 1eam the second foreign language only when they are in the e1eventh grade. Many German- or French teachers have to change their own subjects into another subject. The quality of education wiU go down. Changes should be taken place gradually in order t。 prevent side effects.

생태학적 관점에 입각한 환경 교육 과정 개발 연구의 일환으로, 초, 중, 고등학교의 과학 교과서에 실려있는 환경 관련 내용을 1)환경 오염의 원인, 2)환경 오염의 실태, 3)생태계 원리, 4)환경 위기극복을 위한 노력 등 4분야로 구분하여 분석하였다. 본 연구 결과, 초, 중, 고등학교 과학 교과서에 실려있는 환경 관련 내용은 생태주의적 관점보다는 환경주의적 관점에서 저술된 것으로 파악되었고, 또한 환경 관련 내용들은 서로 교과목간 또는 교과목 내에서

This paper was made for the purpose of research for direction on earth science subject matter of high school in Korea. For this purpose, we 1) reviewed the essence of science and goals and contents of science education, 2) reviewed the change of education of earth science subject matter, 3) investigated earth science teacher's opinion by questionnaire. The results were as follows: 1. Earth science subject matter must provide to students scientific process and knowledge - Process : to promote student's concerns for an interest in nature surrounding them, to help students develop and method in solving problems and its application for problem solving, recognition of variables of scientific method, to promote fundamental experiment and skills for scientific inquiry, etc. - Knowledge : provide systematic knowledge than simple rote, to help students understand concepts of recent scientific knowledge, contains STS, etc. 2. Earth science education must consider educational philosophy and educational psychology education of scientific literacy, partial professional education, conformity of development stage, sequence between school levels, attitudes to adaptation of scientific knowledge, method, skills and problem solving toward future positive attitudes to science, moral sense of science, minimum essense and difference of lines, open of upper limit, understanding the specific character of earth science, scientific knowledge development continuously, relationships of other subject matter, etc.

In recent years, there has been a great change in the earth science. Introducing new theories such as sea floor spreading and plate tectonics theories, sophisticated geological phenomena including continental drift, earthquakes and volcanic activities can be scientificaly explained. According to the great change of the concept of earth tectonics, earth science curriculum of domestic and foreign secondary school are now adapting this new concept such as new global tectonics. The aim of this study is to improve curriculum and develope a new efficient teaching-learning method by analyzing the contents of the chapter connected with plate tectonics in the elementary, middle and high school curriculum. For this purpose, American ESCP, CEEP and Korean earth science textbooks were analyzed in terms of general concept, system and construction. As the results, newly setting up the plate tectonics chapter include the contents of the concept of the plate, plate movement and historical back ground of the new global tectonics.

The earth science was set down as a regular subject of high-school curricilum in 1956 and has been constantly transited since then. This study is to discover the theoretical basic of science education by analyzing the background of formation of the curriculum and the process of transition. The aim of this study is to give an important suggestions for the future Earth Science Education. The summary of the study and suggestions for the sixth amendment of Earth Science curriculum are as follows 1. To promote the development of Science Education, Science subjects should be decided to be a compulsory subject by authority and supported financially. 2. It is necessary that the Earth Science be selected as a required subject in both human and natural course ; at least 4 unit for the human study course, and 8 unit for the natural course. 3. In the sixth amendment of curriculum the Earth Science should be fixed as a regular compulsory subject and both experiment and practice should be reinforced.

1. The aim of this study is to find the theoretical foundation of science education and to offer a basic materials and efficient suggestions for the 2000s Earth Science by analyzing and comparing the new curriculum amended in 1988 and the old one amended in 1981. 2. The main contents of this study is to find the problems in curriculum and to suggest the way to improve the curriculum by analyzing and comparing the new and old curriculum. 3. The problems that may appear in the new curriculum are as follows. (1) It's hard to expect the normal Earth Science Education in high school because Earth Science is designated as an optional subject in natural course. (2) It is contradictory to relation in learning to unify the Earth Science I and Biology I into Science I in new curriculum. (3) If the new curriculum goes in effect it is natural that Earth Science teachers quality should be lowered because able students will avoid entering the Department of Earth Science Education in university. 4. The suggestions to help improve the Earth Science curriculum in 2000s are as follows. (1) For the normal Earth Science Education, Earth Science should be designated as a required subject in civic science course as well as in natural course in high school. (2) The aim of Earth Science Education should be amended not to be dicipline centered curriculum but to satisfy the future society or individual's desire (3) The intergrated science should be researched profoundly and it is necessary to name Earth Science Geophysics, which is unified with physics. (4) Natural science curriculum should be amended by the committee constituted with the specialist in science education, scientists, and science teachers ; it is not proper that science curriculum be reached and discussed by an reorganization in which a few specialists in science education join.

The papers of earth science examinations given during the first semester of 1981 academic year were collected from the seventy five high schools randomly chosen all over the country. The examination questions were analyzed and evaluated in order to grasp the current state and issues of earth science education. Some critical remarks and suggestions are made for improvement of the earth science education at the secondary school level.
